| Scientific fields of study such as astrobiology, nanotechnology, and cave and karst science involve the study of images and associated biological, physiochemical, and geological data. In order to ensure interdisciplinary analysis, it is important to make these kinds of datasets available for analysis and curation by the scientific community. The goal of this project is to design and develop an online workspace that enables scientists to collaboratively view, analyze, and annotate such datasets. The prototype contains scanning electron micrographs of karst and cave samples. The target users are the interdisciplinary community of scientists who study karst samples to learn more about critical biological and geological processes and the microbial communities often found in karst terrain. The prototype can inform the design and development of collaborative workspaces in other interdisciplinary fields. | |||
| Using Social Metadata in Email Triage: Lessons from the Field | | BIBAK | Full-Text | 13-22 | |
| Danyel Fisher; A. J. Bernheim Brush; Bernie Hogan; Marc A. Smith; Andy Jacobs | |||
| Email archives are full of social information, including how messages are
addressed and frequency of contact between senders and receivers. To study the
use of this rich metadata for email management, particularly email triage, we
deployed SNARF, a prototype tool which uses social metadata to organize
received email by correspondent, sort received email by past interactions, and
filter email into multiple views. We discuss the lessons from a seven month
deployment, including the value of organizing by personally addressed mail, the
unexpected value of SNARF for email awareness, challenges with handling
workflow, and ways to use social metadata in applications. Keywords: Email overflow; email triage; social metadata; social sorting | |||
| Fond Memory Management System by Using Information About Communities | | BIBAK | Full-Text | 23-29 | |
| Katsuya Hashimoto; Yoshio Nakatani | |||
| In this paper, we propose "yourStory" as an effective reminder management
system to construct a life story from the viewpoint of communities to which the
user has belonged. Our framework helps the user manage his/her personal history
and tell his/her life stories to other users through sharing communities and
episodes. This system provides four kinds of functions: building up a life
story in accordance with community information, output of the "communityTree"
and "lifeChart" data based on the life story, registration of an episode in
relation to a community, and display of various kinds of data, including
"communityTree," "lifeChart," photos and episodes. Keywords: Fond memory; community; life story; episodic memory | |||
| Spatial Electronic Mnemonics: A Virtual Memory Interface | | BIBAK | Full-Text | 30-37 | |
| Yasushi Ikei; Hirofumi Ota; Takuro Kayahara | |||
| This paper proposes a novel idea of the Spatial Electronic Mnemonics (SROM)
that augments human memory by using electronically annotated and/or converted
materials based on places, objects and people in the real world. The SROM
provides effective recall cues for information to be memorized with visual
materials such as digital images captured and modified for easy association. A
basic function as well as structure of SROM and some plans to construct the
SROM is presented. The initial implementation and a preliminary registration
experiment of spatial virtual memory peg are demonstrated. Keywords: Memory augmentation; Pegs; Images; Locations; Wearable computer | |||
| An Assistant Tool for Concealing Personal Information in Text | | BIBA | Full-Text | 38-46 | |
| Tomoya Iwakura; Seishi Okamoto | |||
| This paper presents an assistant tool for concealing personal information in text. Concealing personal information is one of the important roles for protecting privacy in disclosure of public documents, protection of accidental personal information leakages, and so on. However, concealing personal information is very time-consuming, because it is strongly depending on manpower. In order to alleviate tasks of concealing personal information, we have developed a graphical user interface (GUI) tool that has the following three characteristics: 1) Extracting candidates of personal information in text. 2) Presenting the candidates with colors indicating types of personal information. 3) Creating extraction rules for personal information from text including annotations of personal information. The experimental results on tasks of concealing person names in Japanese text showed that processing times of concealing personal names with candidates of person names were about 1.5 to 3.9 times faster than without candidates of person names. | |||
| Effect of Providing a Web-Based Collaboration Medium for Remote Customer Troubleshooting Tasks | | BIBAK | Full-Text | 47-53 | |
| Chulwoo Kim; Pilsung Choe; Mark R. Lehto; Jan P. Allebach | |||
| This study investigates the effect of providing a Web-based diagnostic tool
as a collaboration medium on remote customer troubleshooting tasks with and
without the assistance of a customer call center agent. The study tested three
troubleshooting modes (Web tool alone, call center agent alone, and Web tool +
call center agent). The hypothesis that the Web tool + call center agent mode
would be faster than the other two modes was not supported. However, the
results of the experiment showed that the Web-based self-help diagnostic tool
can be a potentially cost-effective way of providing customer support. The
performance using the Web tool alone was comparable to the call center agent. Keywords: collaborative troubleshooting; communication mode; web-based diagnostic tool | |||
| Natural Language Based Heavy Personal Assistant Architecture for Information Retrieval and Presentation | | BIBAK | Full-Text | 54-63 | |
| Algirdas Laukaitis; Olegas Vasilecas; Vilnius Gediminas | |||
| In this paper we present the progress of the natural language usage as the
paradigm for information extraction and presentation in the enterprise
environment. Distributed heavy personal assistant architecture and its
implementation is presented as the solution to overcome difficulties related of
the natural language use in the information systems development. A new
methodology based on connectionist and symbol processing techniques for a
knowledge worker to process his documents and utterance is suggested. Then we
suggest the results from those processes to reuse for new documents
classification and generation of small atomic applications. Finally the
experiment is presented. We compare Microsoft EQ, IBM WebSphere Voice Server
NLU toolbox and our solution for concepts identification accuracy. Keywords: Information extraction; Natural language understanding; Ontology; Personal

| "Seeing Is Not Believing But Interpreting", Inducing Trust Through Institutional Symbolism: A Conceptual Framework for Online Trust Building in a Web Mediated Information Environment | | BIBAK | Full-Text | 64-73 | |
| Emma Nuraihan Mior Ibrahim; Nor Laila Md. Noor; Shafie Mehad | |||
| Trust has become an essential prerequisite for customer relationship
building. Implementing institutional mechanisms seems to be an obvious outcome
in inducing trust, rather than the result of independently motivated decisions
of the user's interpretation on the institutional design features to be
trustworthy. Proponents of this idea argued by understanding the concept of a
sign and its related properties, it is possible to improve the analysis and
design of interface design elements within web environment to induce trust.
Drawn from established theoretical work on institutional based trust and
semiotic, the concept of Institutional Symbolism and its four underlying
dimensions are proposed to facilitate thinking and perception as to how trust
can be built through signs comprehension. Conceptualized in the context of web
mediated information environment, the implications of these dimensions on web
site design and future work is further discussed. Keywords: Web Mediated Information Environment; Institutional based Trust;
Institutional Symbolism; Semiotic | |||
| Exchanging Graphical Emails Among Elderly People and Kindergarten Children | | BIBA | Full-Text | 74-83 | |
| Megumi Mitsumoto; Sanae H. Wake | |||
| Email is a convenient tool, however, it is still difficult for elderly people and kindergarten children. If they can learn to use it, their ability to communicate may be remarkably increased. Therefore we developed two kinds of email software 'Gin-Mail' for elderly people and 'Ocha-Mail' for kindergarten children. They adopt a pen-based interface with a tablet PC. Users write email using Ink function, and software sends it as an attached image file. There are two modes in it, User mode and Maintenance mode. User mode offers only minimal functions to prevent misoperation. We devised each user interface in accordance with the user's characteristics. 'Ocha-Mail' and 'Gin-Mail' are accessible to kindergarten children and elderly people respectively. Our goal is to encourage interactions among different generations by through the use of email. | |||
| Shadow Arts-Communication: System Supporting Communicability for Encounter Among Remote Groups | | BIBA | Full-Text | 84-94 | |
| Yoshiyuki Miwa; Shiroh Itai; Shoichi Hasegawa; Daichi Sakurai | |||
| The present authors have developed a communication system WSCS (Waseda Shadow Communication System), with which your remote communicating partner (or you) can be positioned and appeared 3-dimensionally in your (or your partner's) real space, by exchanging body shadows each other. With this WSCS, we have reported previously that cooperative work and conversation can be achieved with your remote partner while taking the spatial distance ("Maai" in Japanese) between you and his shadow appeared in your space. For further development of the WSCS as Arts Communication System being supportive to a generation of co-creative "Encounter Ba", a creative expression technique has been investigated in the present study. With this technique, a relationship between you and your remote partner at the encounter occasion can be strengthened from the following two points of view. The first point is related to a supportive method to a self-organization of "Ba" at the encountering "Now, we are here", by enriching the co-existing feeling between remote participants. For this specific aim, the application software was developed with which remote participants can perform embodied interaction between remote groups using a virtual shadow ball. The second point relates to a method by which scene of the past time was reproduced across the time scale and the bodily expression of the concerned person can be trace-experienced. For this point, a co-experiencing type archive software was developed with which one can put himself at the past scene by processing of shadow images of recorded person(s), so that one can share experiences with concerned person(s) while entering the past scene across the time scale. After installing these software programs into WSCS, several communication experiments were conducted. It was found that (i), with the first software, a similar effect as an ice-breaking activities occurred at a workshop was recognized, and the software was found effective to develop a workshop which shares a mutual context among groups, and (ii), with the second program, since participants and the concerned person can be present at the same scene, changes in feeling/emotion of the concerned person can be conveyed directly via the embodiment. | |||
| Visual Feedback to Reduce the Negative Effects of Message Transfer Delay on Voice Chatting | | BIBAK | Full-Text | 95-101 | |
| Kazuyoshi Murata; Megumi Nakamura; Yu Shibuya; Itaru Kuramoto; Yoshihiro Tsujino | |||
| Voice chat system is one of the most popular communication systems using
computer networks. There is considerable delay to transfer the sender's voice
to the receiver on usual voice chat system. The message transfer delay often
causes unintentional interruptions and makes participants of the system feel
confused. It is considered that such negative effects occur because
participants can't know the status of their voice playback in remote site. In
this paper, two types of remote status monitoring systems are introduced to
reduce unintentional interruptions and confused feeling. Then, it is confirmed
experimentally that these systems were effective to reduce these problems. Keywords: Voice Chatting; Message Transfer Delay; Unintentional Interruption; Status

| Friendly Process of Human-Computer Interaction -- A Prototype System in Nostalgic World | | BIBAK | Full-Text | 102-109 | |
| Seiko Myojin; Mie Nakatani; Hirokazu Kato; Shogo Nishida | |||
| In the interactive model considered herein, a user can be made to feel that
the virtual world exists as tangibly as the real world does. Once "Friendly
Process of Human-Computer Interaction" launches, a user can wait to see what
happens before he or she takes action. Even if a user does nothing, the program
still runs. A PC user is an audience. The computer program performs for its
user audience. If the user is interested in the computer program's behavior,
that user interacts with the PC as its audience. The purpose of our work was to
examine the potentiality and significance of our interactive model. We
integrated our concepts into our interactive design. In order to evaluate our
concepts, we prepared three interactive movie system prototypes. The creation
of our prototypes is well underway toward effectuating our concepts. After we
improve our prototypes, we will then need to evaluate them. Keywords: entertainment; emergent relationships; nostalgia; image recognition | |||
| Communication Environment for Sharing Fond Memories | | BIBAK | Full-Text | 110-117 | |
| Mie Nakatani; Seiko Myojin; Masumi Shimizu; Hirokazu Kato; Shogo Nishida | |||
| Fond memories provide not only warm feeling to those who possess them, but
also bonds that tie people who share them together. Utilizing this property, we
propose to develop an environment where people can share their feelings for
fond memories, as well as empathize and communication with each other. We
consider this environment like a park, where you drop in and take a rest on a
bench, look at the fountain and feel comfortable atmosphere away from your
daily life. Instead of benches or fountains, we provide some triggers for fond
memories. We named this environment "Reminiscence Park". An example of the
triggers for remembering in Reminiscence Park is the old popular song common to
the users' younger days. We developed a prototype system modeling a music box.
Opened by one or more people, the box starts to play a common song from their
youth. Keywords: fond memories; reminiscence; park; popular song; music box | |||
| Experimental Comparison of Multimodal Meeting Browsers | | BIBA | Full-Text | 118-127 | |
| Wilfried Post; Erwin Elling; Anita H. M. Cremers; Wessel Kraaij | |||
| This paper describes an experimental comparison of three variants of a meeting browser. This browser incorporates innovative, multimodal technologies to enable storage and smart retrieval of captured meeting. Over a hundred subjects had to work in a design team in which they had to prepare and carry out a final meeting, while supported by one of the browser variants. In one condition, teams worked without such support. Measures on individual characteristics, the team, the process and outcome of the project, and the usability of the browsers were taken. The results indicate that a multimodal meeting browser can indeed improve meetings. Further analysis of the now available data will provide additional insight into how browsers can contribute to more efficient and satisfactory meetings, improved team performance and higher quality project outcomes. | |||
| How Participation at Different Hierarchical Levels Can Have an Impact on the Design and Implementation of Health Information Systems at the Grass Root Level -- A Case Study from India | | BIBAK | Full-Text | 128-136 | |
| Zubeeda Banu Quraishy | |||
| To build the effective information systems Scandinavian tradition emphasizes
and encourages the participatory design methods which involves both designers
and users equally in building the systems. While the main intention of
Scandinavian tradition is to refocus the dominant orientation of systems
developers by involving users but one really wonders whether it can be applied
in the context of developing countries particularly in a country like India
where the structures are rigid, hierarchical and strongly bureaucratic in
nature. In spite of the fact that health sector being a key social area in
India's developmental administration it is highly fragmented and receives low
priority. In India, while the general administration is mostly concentrated at
the district level, health and family welfare administration has been
centralized at state and central levels. This coupled with the excessive
concentration of powers in the secretariat system of governance, has
considerably centralized planning and monitoring. Keeping in view the above
complexities and challenging conditions this paper tries to understand using
case study as a method how participation at different levels affects the design
and implementation of Health Information Systems in primary health care sector
in India. Keywords: Participatory Design; Health Information Systems Programme; Primary Health

| Media Sharing and Collaboration Within Mobile Community: Self Expression and Socialization | | BIBAK | Full-Text | 137-146 | |
| Youngho Rhee; Kiran Pal Sagoo; Jayoun Lee; Juyoun Lee; Doekwon Kim; Youngwan Seo | |||
| The importance of social relation has never been as vital as of now, in an
age of sound bites, aging population and busy work schedule, contemplating
social behavior has become a rarity. The 'Structuration' theory [2] elaborates
the fact that how much social relation's are important in human life. Here we
re-define basic concept and category (types) of mobile community. A realization
of mobile communities through unified UI for mobile devices is believed to
provide users efficient communication ways while satisfying properties of
various communities. Such unified UI led to drive an adaptive and intuitive
user interfaces that depict real-time interaction involving multiple parties,
contents and activities. Many different scenarios emerge with the proposed UI
to give a deeper thought and understanding about the role of mobile community
in everyday life and help promoting user's communication experience. Keywords: Mobile Community; Visualizing Social Interaction; Community Architecture and

| Disseminating and Sharing Information Through Time-Aware Public Displays | | BIBAK | Full-Text | 156-165 | |
| Marcela D. Rodríguez; Ángel G. Andrade; Maria Luisa González; Alberto L. Morán | |||
| Organizations use several methods to communicate formal and informal
information. Currently, message boards or corkboards are used as a means for
sharing information, coordinating activities and communicating with others.
Using our organization as a case study, we observed that there are many message
boards around the physical environment and most of them are covered with
documents announcing upcoming meetings, seminars, conferences and other events.
Besides that, some of the documents were out-of-date which makes it more
difficult for users to find information that is relevant for their activities.
To support the dissemination of information in organizations, we are proposing
a Time-aware Public Display System that enables organization personnel to
become aware of relevant information in a timely fashion. We used the
Perspective Wall visualization to enable the categorization of the information
into topics and dates. We evaluated the system design which shows that users
considered appropriate and useful the presentation of information on the
Time-aware Public Display. Keywords: Information presentation; Workplace Study; Software Agents | |||
| A Tactile Emotional Interface for Instant Messenger Chat | | BIBAK | Full-Text | 166-175 | |
| Heesook Shin; Junyoung Lee; Junseok Park; Youngjae Kim; Hyunjoo Oh; Taehwa Lee | |||
| Instant Messaging (IM) is becoming as the dominant means of communication
over the Internet. The popularity of IM has led to significant developments in
the sophistication of the software. There have been a number of attempts to
deliver emotional content through IM. The sense of touch has been a focus in a
number of these research projects [1], [2], but there have been no
implementations of tactile IM that have successfully bridged the gap to public,
widely deployed use. In this paper, we describe a tactile interface designed to
convey emotional content and focused on intuitive input and sensorial output
methods to be applied in a public IM client. The initial stage of this research
involved a fundamental investigation into IM usage patterns. We distributed a
questionnaire to gain insight into user's requirements, and received completed
results from 79 people in their twenties (32 male and 47 female). Regarding how
the tactile stimulus should be integrated into the environment, 50% felt a
mouse (26%), a glove (14%), or a keyboard (10%) based display would be
appropriate and afford easy physical contact during IM. Furthermore, they
expressed a desire for tools to enable them to easily author their own tactile
sensations. From the data gathered in this survey we developed a design concept
for the physical interface. And we selected a set of emoticons most used in IM
and defined both tactile and visual information to help emotional expression
for each emoticon. We named these enhanced emoticons TCONs (TouchCON, Touch
Emoticon). We defined 6 TCONs and 3 intuitive tangible input methods. We played
our TCONs on a physical interface device, called the TCON Display, during
public IM. The TCON Display consisted of three components, two devices shaped
like cartoon hands, the other like a pair of lips. These devices included
various output and input systems: vibrating motors, pin actuators, Heat coil,
pressure sensors, buttons and LEDs. We also implemented a TCON Editor to allow
users to create TCONs and for testing our research. The TCON was applied to a
public IM system, NateOn, just like graphical emoticons. We tested the TCONs
and tactile emotional interface system with 12 users test in their twenties (6
male and 6 female) and received a positive response. Keywords: Instant Messaging (IM); Emotional Interface; Sensorial Interface; Intuitive

| A Theoretical Framework of Co-purposing in Systems Design | | BIBAK | Full-Text | 176-184 | |
| Modestos Stavrakis; Nikos Viorres; Panayiotis Koutsabasis; John Darzentas | |||
| The paper outlines a theoretical framework for the conceptualisation and
design of collaborative systems for design organisations. The intent is to
examine and support the idea of 'co-purposing' as an influential design
metaphor for the analysis of design teams and the development of design support
collaborative systems in contexts where systems' designers collaborate with
their clients. By offering associations to the work activities and the social
interaction of designers in actual design workspaces, we propose that the
metaphor of 'co-purposing' can stand as an alternative perspective in the
analysis and design of potentially new realisations of computer supported
cooperative work systems for supporting teamwork. Keywords: co-purposing; collaborative systems; e-collaboration; postmodern systems

| Toward Adaptive Interaction -- The Effect of Ambient Sounds in an Ultra-Realistic Communication System | | BIBAK | Full-Text | 185-194 | |
| Noriko Suzuki; Ichiro Umata; Tatsuya Kitamura; Hiroshi Ando; Naomi Inoue | |||
| Our research focuses on ambient sounds as a key to implementing an ambient
atmosphere of people, that is, the feeling of another's proximity or presence.
Such knowledge is sought for constructing an ultra-realistic communication
system with shared reality. This study examines whether people's impressions
and behaviors are affected by (a) the existence or (b) non-existence of ambient
sounds. A pilot study is conducted by using the ambient sounds of a newspaper's
pages being turned and a glass being placed on a table in an adjacent room. No
difference in the subjects' surface behavior between the two ambient-sound
conditions is observed explicitly. However, the preliminary results suggest
that participants feel an ambient atmosphere of people in the next room when
the ambient sounds are output. They also suggest that the participants become
nervous as they feel the presence of other people. This study demonstrates the
importance of investigating the fundamentals of an ambient atmosphere in
interaction via an ultra-realistic communication system. Keywords: Ultra-realistic communication system; Ambient atmosphere; Ambient sound;

| The high penetration of mobile devices implies that we are closing up to the
vision of ubiquitous media environments. This paper reports from a broad survey
about barriers, use patterns, and motivations for using mobile media services.
The aim is to contribute to the understanding of mobile service adoption
process by studying users in different phases of the adoption process. The
findings imply that mobile services are still not adopted and ubiquitously
ingrained in use patterns. There is still a long way to go. Keywords: ubiquitous media services; mobile service adoption | |||

| A New Method for Teachers and Students to Record Daily Progress in a Class | | BIBAK | Full-Text | 245-251 | |
| Akinobu Ando; Kazunari Morimoto | |||
| The purpose of this study is to help to improve teachers' instructions by
using information and communication technology. We developed a new method with
the LAPP (Linux, Apache, PostgreSQL, and PHP) system. We adopted a mobile-phone
as a terminal device. Using this system, a teacher could record easily and
quickly students' learning situations also with taking pictures and evaluation
data. A teacher could understand how well a particular student and whole
students during a lecture -- numerical evaluation values, average and the
standard deviations of classroom average. We used this system actually for
improving a lecture of programming and checking students' wood works. In both
using, our system could work without any trouble. Understanding trends in
students' learning, we found that this system could help teachers' instructions
for students and reduce teachers' load. Keywords: mobile-phone; interaction; learning situation; taking picture; improving a

| In e-Learning study, the materials are the only environment. Therefore, the influence which these have on a students' emotion has big influence on progress of study. The purpose of this study, from a standpoint of making easy-to-follow e-Learning materials, is to construct the foundation for a methodology to evaluate the materials from emotional aspect. At first we re-corded the basic EEG during mental calculation. Second, we tested two different levels of materials which had 3 important learning points. We recorded subjects' EEG, then analyzed and compared with the basic EEGs. The result suggested us that at the learning point, where the α-wave power was greater than the basic one and the β-wave was less than it, the content was not able to understand. | |||

| Privacy and the Public Educator | | BIBAK | Full-Text | 289-298 | |
| Melissa Dark; Clewin McPherson | |||
| As of 2003, 99% of K-12 schools in the United States use the Internet. With
the increased use of databases and other technologies to manage data in K-12
institutions, an inherent threat to the privacy and confidentiality of that
information has also increased. Over the last decade, with the increased use of
these technologies, there has also been an increase in the number of
privacy-related violations that have occurred, both in industry and in the K-12
environment. There are a plethora of security technologies that can be used to
improve privacy; however, organizations such as K-12 schools often cannot
afford to hire IT staff versed in the state of the art. Furthermore, technology
alone will not address security and privacy problems; policy is an essential
ingredient for any organization. This study is a gap analysis investigating
privacy practices of public educators in the Midwestern portion of the United
States. The significance of the work is that we cannot improve the practices
unless we understand deficiencies in current privacy practices and perceptions. Keywords: Privacy practices; privacy perceptions; privacy risk; public education | |||

gardening metaphor. Nonetheless, there is a research gap in the metaphor
application, where there is yet a formal elicitation undertaken towards it.
This paper intends to answer three questions: How does knowledge gardening
metaphor supports knowledge sharing within a user interface? What properties
should the overall user interface have to support user-oriented environment?
How can the knowledge gardening metaphor be elicited? Henceforth, a description
on the user interface design incorporating knowledge gardening metaphor is
discussed. Steps undertaken in a metaphor elicitation are also provided. Keywords: Knowledge Sharing; User Interface Design; Metaphor; Metaphor Elicitation | |||

imposed in the number and types words used. Keywords: e-learning; rehearsal; Cognitive psychology; Dispersion-analysis; summarize | |||
| Function Interfaces Assessment of Online Game Websites in Great China Area Using Content Analysis | | BIBA | Full-Text | 337-346 | |
| Chi-I Hsu; Chaochang Chiu; Chich Hua Su; Ping-Ju Wu; Yuan Jie Yang | |||
| Online game websites can not only provide players with a hyperspace for enjoying game playing, but also with a service platform for diverse community interactions, information sharing, and online transactions. Based on the four virtual spaces proposed in Angehrn's (1997) ICDT model: virtual information space (VIS), virtual communication space (VCS), virtual distribution space (VDS) and virtual transaction space (VTS), this research developed a content architecture for analyzing the function interface of online game websites. 26 online game websites are chosen as sample sites. This research found that most of the websites investigated provide good service functions in both VIS, but require further improvement of their VTS functions. Certain suggestions are proposed to the online game websites in Great China area. | |||
| Impact of Interactive Learning on Knowledge Retention | | BIBAK | Full-Text | 347-355 | |
| Mohamed Ibrahim; Osama Al-Shara | |||
| There is amble evidence that supports true interactivity, both in the
interface and in the presentation methodology, will further enhance learning
and knowledge retention among students. The real challenge is how to implement
it, measure and evaluate this outcome. This paper presents findings that look
into the efficacy of the combination of virtual environments and interactive
teaching techniques in enhancing learning and increasing the knowledge
retention level of students. It is now widely accepted that the conventional
way of lecturing students has certain limitations. E-learning and the use of
ICT, interactive tools in the education field has proven to be effective in
assisting the teaching and learning experience. It has been observed that the
one way communication method of lecturing with limited or no opportunity for
feedback from students and audiences in general has a major impact on their
attention span and the retention level. There are issues related to the
establishment and implementation of interactive learning tools as an aid for
teaching and especially in continuous evaluation of students' achievements. We
point out that it is not only the 'teaching' tasks that are impacted by the use
of ICT but also current methods of evaluation including written examinations
which have proven to be time consuming and inaccurate reflection of students'
achievements. The introduction of interactive learning and evaluation has
several advantages and this paper will give a convincing support to the fact
that the advantages are more than the fact that it makes the teaching and
evaluation process easy, simple and rapid. Educators should not fail to adapt
and respond to the needs of 21st century bust and multi-tasking students for
innovative learning methods, i.e. interactive learning. The role of education
institutions and educators in the future will become demand-driven; to satisfy
technically sophisticated student clients. The paper recommends that we should
not ignore the use of interactive technology used as it should be, as a tool,
to enhance sound pedagogical methods, however, we should also be able to
measure its contribution in enhancing teaching and learning. It is pertinent to
synthesize a framework that encompasses ways to compliment existing methods of
teaching with interactive learning. Keywords: interactivity; simulation; elearning; pedagogy | |||

| Context Aware Human Computer Interaction for Ubiquitous Learning | | BIBA | Full-Text | 364-373 | |
| Chulho Jeong; Eunseok Lee | |||
| In the past year, the majority of conventional learning schemes have been transformed offline, gradually adapting E-Learning and M-Learning through the evolution of IT technology. In order to achieve effective learning, existing static schemes of learning must be transformed in all domains, to deliver true personalized learning depending on various user characteristics. Offering a conceptual background that supports this environment is the foundation of ubiquitous learning. Ubiquitous learning exists in the physical space of everyday life. It is possible to compose learning components existing in the activity space of an intelligent network. Adaptive learning in such ubiquitous environments is a significant learning step. In a general sense, our aim regard Ubiquitous computing is pursuit in the same light with Human Computer Interaction is pursuit by related works. However, in order to achieve sufficient improvement, ubiquitous learning requires 1) learning system has to provide learner centered learning contents what learner wants, 2) and through consideration of learner's learning device and learning environment, it has to offer learning contents. In this paper, a system supporting the dynamic configuration of user optimized learning objects, and the transmission of learning content irrespective of the learner device used, is designed and implemented. In addition, through the development of an effective learning model, the effect on learning is maximized. | |||

| Elahe Kani-Zabihi; Gheorghita Ghinea | |||
| The purpose of this study was to determine user suggestions for a typical OPAC (Online Public Library Catalogue) application's functionality and features. An experiment was undertaken to find out the type of interactions features that users prefer to have in an OPAC. The study revealed that regardless of users' Information Technology (IT) backgrounds, their functionality expectations of OPACs are the same. However, based on users' previous experiences with OPACs, their requirements with respect to specific features may change. Users should be involved early in the OPAC development cycle process in order to ensure usable and functional interface. | |||
| The Effectiveness of Educational Technology: A Preliminary Study of Learners from Small and Large Power Distance Cultures | | BIBAK | Full-Text | 384-393 | |
| Elizabeth Koh; John Lim | |||
| The cultural background of learners has been highlighted as crucial in
determining the effectiveness of educational technology. This paper focuses on
the influence of power distance in determining the effectiveness of educational
technology. Utilizing a multiple case study, we examined the perception of
learners from small and large power distance societies in terms of satisfaction
with learning, self-efficacy with educational technology and perceived
learning. Our findings show that the availability of educational technology
enhances the learning outcomes of both cultures. The study suggests the notion
that learning outcomes differ for learners from small and large power distance
cultures. Keywords: Educational Technology; Culture; Power Distance; Effectiveness | |||
| Human-Mediated Visual Ontology Alignment | | BIBAK | Full-Text | 394-403 | |
| Monika Lanzenberger; Jennifer Sampson | |||
| We develop a multiple-view tool called AlViz, which aims at supporting the
ontology alignment process visually. Combing views on several levels of
abstraction, the tool tries to make the 'relatedness' between entities
accessible. Based on a literature study we identified relevant phases emerging
in ontology alignment. We extended a general alignment framework in order to
reflect the adoption of visualization techniques. This framework builds the
background for our user study. We evaluate visual ontology alignment with AlViz
in three stages: (1) Participative software development, (2) usability
evaluation, and (3) utility study. The evaluation methods proved viable even
though our study design is challenging. Keywords: Ontology Alignment; Information Visualization; Evaluation | |||

| Context Modeling and Inference System for Heterogeneous Context Aware Service | | BIBAK | Full-Text | 413-422 | |
| Seungkeun Lee | |||
| Context can be utilized as an effective source of information for supporting
the user system interface under the ubiquitous environments. The context
awareness function forms the basis of the studies regarding the ubiquitous
computing environment for creating numerous smart spaces, and a context
awareness service is usually based on the context awareness system or
middleware. However, conventional context modeling approaches based on ontology
bear several problems. First, a context awareness service must share the
context information with other context awareness services in the designing
phase. Second problem is a context uncertainty, which can arise in the process
of deducing the data acquired from the sensor into the context information
based on the dynamic modification of the context ontology, must be resolved.
This study proposes the context management system based on the dynamic context
ontology management method, which involves the hierarchical context management
method using common context and the paper proposes a method for resolving the
context uncertainty problem of interpreting the data acquired from the sensors
as two or more types of context information. Keywords: Context Aware; Context Modeling; Ubiquitous Computing | |||
| Skill Transfer from Expert to Novice -- Instruction Manuals Made by Means of Groupware | | BIBA | Full-Text | 423-429 | |
| Chung-Yong Liu; Yasufumi Kume | |||
| Modern manufacturing industry changes dramatically following the fast progress of mechanical improvement and informatics development. Young people focus on learning new techniques in order to catch up the fast progress. Traditional industrial skills are missing step by step that will be a problem for modern industrial manufactures. The technological generation gap also causes damage in manufacturing industry. Elder experts who accumulated many traditional industrial skills faced the problems of retirement and strict competition. Young novices receive modern industry technique trainings, but still require traditional skill to maintain the industrial manufacture. The skill transmission from elder expert to young novice is known as an important course. In Japan, industry pays a lot of concern at the decline in mastery of skills technology. Based on the importance and difficulties of skill transmissions, an idea model was searched and established in this study. We choice screw manufacture as a representative industry in this study because screw manufacture required traditional skills and modern techniques. A manual introducing traditional skill and integrating computer science could transmit technologies smoothly from elder expert to young novice. Computer science here is used to link generation gap, to introduce traditional skill delicately in order to keep all the detail tricks and lively in order to be accepted by novice. The transmission efficiency and efficacy both will be considered. | |||

| The number of experts in various fields such as manufactures, traditional
arts/crafts decreases because of their retirement in Japan. In the field of
nuclear power generation, it also becomes problem especially in maintenance.
The goal of this study was to develop an advanced instruction video system to
support skill acquisition. We proposed to use eye movement as one of the
expert's skill information, and developed the system for supporting recording
skill (scene video and the point of regard of an expert), making teaching
materials in XML format and learning skills with the special user interface.
Evaluation will be necessary by experiment to confirm the effectiveness of the
training method. Keywords: Eye tracking; Skill; Training; Expert; XML | |||
| MOCET: A MObile Collaborative Examination Tool | | BIBAK | Full-Text | 440-449 | |
| Sergio F. Ochoa; H. Andrés Neyem; Gabriel Bravo; Emilio G. Ormeño | |||
| This paper presents a mobile collaborative application to support the
Collaborative Examination Technique (CET). This software tool, named MOCET,
keeps the metaphor of the student's paper notebook used to support CET
processes. In addition, it provides solutions to overcome the two main
limitations identified on CET: (a) the inefficiency to support the building and
sharing knowledge processes carried out by students during the pre and
post-test activities, and (b) the high cost in time spent by instructors to
carry out the examination process. Although MOCET is able to run on several
computing devices, it has been specially designed to be used on Tablet PCs and
PDAs and interact with the users using a pen device. This tool replaces the
student's paper notebook during exams and supports students and instructors in
every phase of the examination process. MOCET has been tested in two computer
science courses and interesting results were obtained. Keywords: Student Examination Process; Mobile Collaborative Tool; On-Line Tests | |||
| Requirement Analysis of the Portal Site Serving Distributed Climate Data for e-Science | | BIBAK | Full-Text | 450-456 | |
| Taezoon Park; Lan Zhao | |||
| The growth of grid computing facilitates the discovery of scientifically
meaningful findings from the result of computational simulations by providing
enormous amount of computing power and huge volume of storage area. As the
computer technology advances, the relative portion of the time required for
preparing and analyzing the result of the calculation increases because the
complexity of the problem to be solved by grid computing also increases. In
order to provide transparent and flexible interface to various groups of users
who have different objectives, multi-layer design is applied for developing
data portal for climate data. This paper presents three-layer model with four
user groups which represents student, teacher, researcher, and administrator.
The functionalities for job submission, post-processing, data management,
content management are distributed into three different layers of complexity
which is categorized as basic, intermediate, and advanced. Keywords: grid computing; portal; distributed data system; user requirements | |||

| Simulation-Based Automated Intelligent Tutoring | | BIBAK | Full-Text | 466-474 | |
| Barbara Sorensen; Sowmya Ramachandran | |||
| Simulation-based training has traditionally relied on live simulations for
the specification of training scenarios. However, both the logistics and cost
of live simulation constrain how often that form of training can be accessible.
As the healthcare community begins to invest significantly in simulation-based
training, it is running against the limitation of requiring expensive hands-on
instructor-led facilitation to make it effective. New technological advances
applied to simulation-based training provide automated coaching and feedback
which reduce the need for instructor facilitation, thus making simulation-based
training cost-effective and feasible. The design and development of SimCore
(Simulate, Coach, Review), a simulation based framework that adds intelligent
performance assessment and coaching facilities to training simulations, is
discussed. Through the use of SimCore, simulation developers are able to
convert their simulations into automated, intelligent tutors. SimCore is a
unique application that includes a scenario authoring tool tailored to the
medical domain that can be used to rapidly customize existing scenarios or to
create new ones. Keywords: Simulation-based training; Intelligent Tutoring; Scenario Authoring Tool | |||

| In this paper, we introduce a virtual pop-up book system using Augmented
Reality technology. This system displays 3D virtual objects on the real book
based on pose and position estimation of the camera. Although many marker-based
methods have been proposed, a picture book with markers looks unattractive. Our
system does not use any markers. We describe four advantages for the virtual
pop-up book. Firstly, 3D rendering helps readers understand scenes. Secondly,
characters look lively by using motions. Thirdly, author of the picture book
can use the new representation, which mixes 2D and 3D rendering. Lastly, it can
express time changes using animation. Keywords: pop-up book; Augmented Reality; texture tracking | |||
| A Mobile Environment for Chinese Language Learning | | BIBAK | Full-Text | 485-489 | |
| Chang-Chih Tseng; Chun-Hung Lu; Wen-Lian Hsu | |||
| Due to the diversity of mobile device and wireless network's progress,
mobile learning has become a possible and convenient way to support learning
activity, whether it was in or out of classroom. There have been some
researches showed that using such devices in the course can improve learners'
performance and arouse their motivation, cases like bird watching, plant
observing, museum navigation and tourist guidance. Chinese language was
considered difficult to learn all the time, because of its complicated shape,
different pronunciations and multiple meanings. In this paper, we propose a
system that works on PDA for foreigners to learn Chinese. The design concept
derived from geographic information sharing, people will use PDA to explore the
city they live, and gradually find virtual messages around them, thus enhance
their Chinese communication skill. Keywords: Mobile learning; Chinese learning; GIS; Geotagging | |||

| Recently, various ways are being explored for enhancing the fun of computer games and lengthening the life cycle of them. Some games, add realistic graphic effect and excellent acoustic effect, and make the tendencies of game players reflected. This paper suggests the method to collect and analyze the action patterns of game players. The game players' patterns are modeled using FSM (Finite State Machine). The result obtained by analyzing the data on game players is used for creating NPCs (Non-Player Characters) which show new action patterns by altering the FSM defined previously. This characters are adaptable NPCs which is learnable the action patterns of game players. The proposal method can be applied to create characters which play the role of partners with game players or the role of enemies against game players. | |||

| A Navigation System Using Ultrasonic Directional Speaker with Rotating Base | | BIBAK | Full-Text | 526-535 | |
| Kentaro Ishii; Yukiko Yamamoto; Michita Imai; Kazuhiro Nakadai | |||
| This paper proposes new method for object reference which enables a person
to find surrounding objects and develops a navigation system named CoCo. CoCo
employs an ultrasonic directional speaker with a rotating base. Ultrasonic wave
transmitted by an ultrasonic directional speaker is converted to audible sound
when it reflects on floor, wall, or object. Based on this property, CoCo can
emit audible sound from arbitrary place using a rotating base. When CoCo
navigates a person to an object, CoCo transmits ultrasonic wave so as to hear
audible sound continuously from the line between the ultrasonic directional
speaker and the object. We designed and implemented an object management system
as an application using 3D position sensors and a navigation system CoCo. This
paper shows how CoCo navigates a person to an object using position data from
an object management system. Keywords: object reference; ultrasonic directional speaker; ultrasonic wave; position

| Power Saving Medium Access for Beacon-Enabled IEEE 802.15.4 LR-WPANs | | BIBA | Full-Text | 555-562 | |
| Joongheon Kim; Wonjun Lee | |||
| To construct constraint-free human-computer interaction (HCI) environments, the wireless communication is one of the most essential research issues. Among the numerous wireless communication technologies, IEEE 802.15.4 low-rate wireless personal area networks (LR-WPANs) is the most suitable for ubiquitous and pervasive HCI environments, such as home networking applications, monitoring systems, and so on. In LR-WPANs, the power-efficiency is one of the most attractive issues. Therefore, this paper proposes a power saving medium access scheme for star topology beacon-enabled LR-WPANs. To achieve power efficiency, we turn off communication modules when the time slots are not used for data communications. On the other hand, we turn on the modules. The proposed scheme predict the time for data communications in a given superframe structure. Our simulation result shows that our algorithm achieves desired properties. | |||
| Dynamic Cell Phone UI Generation for Mobile Agents | | BIBAK | Full-Text | 563-571 | |
| Gu Su Kim; Hyun-jin Cho; Young Ik Eom | |||
| A MA (Mobile Agent) is a computer program which autonomously migrates within
the network and works on behalf of a user. With the progress of ubiquitous
computing environments, MA paradigm becomes more useful paradigm because MA
paradigm makes it possible for various user-centric services, such as follow-me
service, private secretary service, and etc. Also, in ubiquitous environments,
the cell phone has very important role, but the cell phone cannot support the
MA technology because J2ME (Java2 Micro Edition) CLDC (Connected Limited Device
Configuration), which is the java platform for cell phone, does not support the
essential facilities for the mobility of the mobile agents such as reflection,
dynamic class loading, and object serialization due to security problem of the
cell phone. So, in this paper, we propose the scheme that the MAP (Mobile Agent
Platform) dynamically generates the UI (User Interface) according to the user's
device. Also, we show the experimental results of our proposed scheme. By using
our proposed scheme, the user gets the service of MA by the cell phone. Keywords: UI generation; cell phone; mobile agent; mobile agent platform | |||
| TCP NJ+ for Wireless HCI | | BIBAK | Full-Text | 572-581 | |
| Jungrae Kim; Jahwan Koo; Hyunseung Choo | |||
| TCP application in wireless HCI environments communicates to each other
frequently through wireless networks. Therefore, it is important that
significant TCP performance is guaranteed in wireless network. TCP New Jersey,
known as the best existing scheme in terms of goodput in wireless networks,
improves wireless TCP performance using the available bandwidth estimation at
the sender and the congestion warning at intermediate routers. Although TCP New
Jersey achieves 17% and 85% improvements in goodput over TCP Westwood and TCP
Reno, respectively, we further improve TCP New Jersey by exploring enhanced
available bandwidth estimation and suitable error recovery mechanism. Hence, we
propose TCP NJ+. It outperforms other TCP variants by 19% to 104% in terms of
goodput even when the network is in bi-directional congestion. Hence TCP NJ+
can provide the best services to user in wireless HCI environments. Keywords: TCP; wireless HCI; Congestion Control; TCP New Jersey | |||

| Integrated Multi-view Compensation for Real Sense Video Interfaces | | BIBAK | Full-Text | 608-617 | |
| Jongbin Park; Byeungwoo Jeon | |||
| Multi-view video is a new multimedia service which provides immersion and
realism using the multiple view channels. However, as the number of cameras
increases, the enormous data volume generated by them inevitably calls for
better video compression and processing algorithms. However, the multiple
images taken at any certain time instants always have inconsistency among the
views in their intensity, color, sharpness, and so on. It not only degrades the
compression efficiency greatly but also causes subjective quality loss such as
dizziness and unnaturalness in random view access. To solve this problem, in
this paper, we propose a new multi-view compensation method which uses the
Kalman filter. It estimates the illumination discrepancy parameters
autonomously both in encoder and decoder. Therefore, our method needs not
transmit any additional data for illumination discrepancy information. Keywords: Multi-view video coding; Illumination compensation; Inter-view prediction | |||
| Analysis of Naturalistic Driving Behavior While Approaching an Intersection and Implications for Route Guidance Presentation | | BIBAK | Full-Text | 618-627 | |
| Toshihisa Sato; Motoyuki Akamatsu | |||
| This study focuses on an analysis of the naturalistic driving behavior
before making a right turn at an intersection. We conducted experiments on a
public road and measured driver behavior, vehicle state, and headway and rear
distances. The results suggest that the positions of the front and rear
vehicles and the vehicle velocity have an influence on the onset location of
covering the brake pedal. Structural equation modeling (SEM) was applied to
estimate these relationships quantitatively. The results imply that the SEM
with latent variables can represent the hypotheses obtained from the analysis
of the measured data. We propose a detection method of unusual driver behavior
by predicting the driver's preparatory behavior using the SEM, and possible new
application of in-vehicle navigation systems is discussed. Keywords: Mobile interactions; Route guidance information; Driver behavior;

| Energy Efficient Route Discovery for Mobile HCI in Ad-Hoc Networks | | BIBAK | Full-Text | 635-644 | |
| Kwonseung Shin; KwangJin Park; Min Young Chung; Hyunseung Choo | |||
| A mobile ad-hoc network [1] is a set of mobile nodes acting as routers in
infrastructureless networking situations. In ad-hoc environments, to extend the
lifetime of wireless mobile hosts, energy-efficient ad-hoc routing protocols
must be designed. However, in conventional reactive ad-hoc routing, the route
discovery operation is triggered whenever a source node has packets to send to
a certain destination, but has no route information for the destination.
Intermediate nodes, then, repeatedly broadcast the message until it is received
by all nodes. This route discovery process could result in excessive drain of
limited battery power and increase collisions in wireless transmission. In this
paper, we propose an energy efficient route discovery scheme using the K-hop
Pre Route Request (PRREQ) message which is only flooded within K hops from the
source node. This reduces the number of nodes that participate in the route
discovery process. Our empirical performance evaluation, which compares our
proposed scheme to the conventional reactive adhoc routing schemes,
demonstrates that proposed enhancement reduces energy consumed in the route
discovery procedure by about 27% when each node initiates a new route at a rate
of 0.05/sec. Keywords: DSR; AODV; RREQ; RREP | |||
| Interaction Design and Implementation for Multimodal Mobile Semantic Web Interfaces | | BIBAK | Full-Text | 645-654 | |
| Daniel Sonntag | |||
| Multimodal mobile interfaces to the Semantic Web offer access to complex
knowledge and information structures. In SmartWeb we try to build multimodal
interfaces to answer very specific closed and open domain questions by natural
language dialogue and multimedia presentations. Advanced user interactions such
as pointing gestures are also supported. We present the interaction design and
its implementation for Semantic Web related knowledge structures, i.e.,
ontology instances and relations, and follow the principle of no presentation
without representation for information content, its presentation, and
interaction possibilities. In particular, we address the challenge to display
interactive text and image results obtained from multiple homogeneous and
heterogeneous information sources. Keywords: Multimodal Dialogue Systems; Interaction Design | |||

| In this paper we propose an optimal information architecture model for
mobile multimedia devices. In our study we first reviewed the information
architecture models of four currently popular mobile multimedia devices, Apple
iPod Video, Nokia N80, Sony Ericsson W800i and Sony PlayStation Portable (PSP).
Then we used Open card sorting method to find out what kind of mental models
does people have for optimal information architecture model. Finally we
compared these two study results together and created a design proposal. Keywords: information architecture model; card sorting; cluster analysis; mobile

| Mach: A Content Generating Engine for Adaptive Multimedia Applications in the Mobile Environment | | BIBAK | Full-Text | 674-681 | |
| Chian Wang | |||
| For adaptive content generation, it means that the application can recognize
a user's preference and consequently retrieve and present the appropriate media
objects stored in the databases. That is, the application presents only the
media objects with the conditions evaluated to be true according to the user's
demand or preference. The feature of adapting presentation contents can
significantly improve browsing results through providing materials that are
more suitable for each individual user. In the mobile environment, some more
changing factors can affect a user's access to the contents generated by the
presentation engine. These factors include location, available bandwidth, past
visits, the currently closest media source, etc. In this paper, we propose an
adaptive content generating engine called Mach for mobility-aware multimedia
applications. Mach's goal is that a single content description file can be
applied to compose various multimedia presentations. By following the
statements of the description file and the user's preference, Mach can
dynamically generate adaptive contents for each class of users. In this way,
the content designer does not need to compose several description files for
each class of users. Mach is based on the XML (eXtensible Markup Language)
standard and thus its platform independence makes our work well-suited to the
mobile environment. Keywords: multimedia; adaptive presentations; content generation; XML; mobile

| e-Sports Live: e-Sports Relay Broadcasting on Demand | | BIBA | Full-Text | 685-693 | |
| Woonhyuk Baek; Anjin Park; Jongin Kim; Keechul Jung | |||
| Electronic Sports (e-Sports) is computer and video games played as competitive sports over the Internet and a local area network, and are provided to users through a TV relay broadcasting system and the Internet due to tremendous popularity of the e-Sports recently. The main drawback of the previous e-Sports relay is to broadcast the e-Sports selected by the provider without viewers' intention, and thus the viewers can not watch desired information. Accordingly, this paper proposes a message-based semi-interactive relay broadcasting system called e-Sports Live over the Internet. The proposed system captures all regions of playing a game, and transfers the regions to a client's viewer. The client can watch desired information by selecting a slice of all regions. However, transferring continually all regions to the client over the Internet leads to a high-traffic due to high-capacity of data. To reduce the traffic, the system transfers all messages occurred in the game such as movements of characters instead of transferring continually all areas, based on resources repetitively used in game such as the whole map and game characters, and the resources are repetitively transferred to the client's viewer in an initial stage. Consequently, the proposed system can reduce the traffic over the Internet by transferring only message, and can perform a semi-interaction by watching desire information, as the client's viewer receives all areas occurred in the game based on resources repetitively used in the game and messages. Now, our system can not apply to TV relay broadcasting, as it does not have buffers for resources, but may be utilized for a variety of fields of interactive TV. | |||
| Privacy Requirements in Identity Management Solutions | | BIBAK | Full-Text | 694-702 | |
| Abhilasha Bhargav-Spantzel; Anna Cinzia Squicciarini; Matthew Young; Elisa Bertino | |||
| In this paper we highlight the need for privacy of user data used in digital
identity management systems. We investigate the issues from the individual,
business, and government perspectives. We provide surveys related to the
growing problem of identity theft and the sociological concerns of individuals
with respect to the privacy of their identity data. We show the privacy
concerns, especially with respect to health and biometric data, where the loss
of privacy of that data may have serious consequences. Moreover, we also
discuss how privacy concerns change according to the individual's disposition
to provide the data. Voluntary disclosure of personal information is more
acceptable to users than if information disclosure is involuntary, like in the
case of surveillance. Finally, we highlight the shortcomings of current
identity management systems with respect to the current privacy needs and
motivate the need of hardened importance of privacy enabling functionalities in
such systems. Keywords: Identity Management; Security; Privacy; Social and Legal Concerns | |||
| Collaboration Between People for Sustainability in the ICT Society | | BIBA | Full-Text | 703-712 | |
| Gunilla Bradley | |||
| At the present Net Work Period of the IT history deep changes are taken place in collaboration between people and human communication, its structure, quantity, and quality. A dominating steering factor for the design and structure of work life as well as private life is the convergence of three technologies, computer technology, tele technology and media technology (ICT). Telecommunication technology has come to play a more a more dominant role in this convergence, especially internet and web technology. Embedded (ubiquitous) computer technology is making the process invisible, and media technology converges within itself (multimedia or cross media). Well functioning organizational and psychosocial communication are an important prerequisite for successful industrial and social change in the ICT society. Managing and working in an organization organized as a network, involves communication between people, groups, units, other organisations, and various combinations of these entities. ICT applications together with deep knowledge and insights in organisational design and management (ODAM) are the keys to social change. The author describes her convergence theory on ICT and Psychosocial Life Environment with special emphasis on psychosocial communication and sustainability in the Net Era of the ICT society. | |||
| The Impact of Verbal Stimuli in Motivating Consumer Response at the Point of Purchase Situation Online | | BIBAK | Full-Text | 713-719 | |
| Asle Fagerstrøm | |||
| This paper is a response to the lack of knowledge regarding actual online
purchase behavior, and introduces behavior analysis as an alternative framework
in studying consumers' purchase behavior. Motivation to confirm an order online
can from the concept of motivating operation (MO) be analyzed as those
antecedents in the environmental setting (included verbal stimuli) that; (1)
have an effect on the consequences of responding, and (2) influence the
responses (including purchase) related to those consequences. Using the
functional analytic framework from behavior analysis, MO is identified as a
likely predictor of consumer tendency to confirm their online orders. Keywords: Online shopping; point of purchase; motivating operation; augmenting;

| Measuring the Screen Complexity of Web Pages | | BIBAK | Full-Text | 720-729 | |
| Fong-Ling Fu; Shao-Yuan Chiu; Chiu Hung Su | |||
| An increasing, degree of rich and dynamic content and abundant links are
making Web pages visually cluttered. This paper presents a numerical tool to
evaluate the screen complexity of a Web page using four critical measurements:
size complexity, local density, grouping, and alignment. In the empirical
study, we first translate the real screens from four first pages on Ebay
auction web sites to serve as model screens that contain the structure of
complexity without content. We subsequently compare the complexity values
calculated from the model screens with the viewers' judgment from the real
screens. The resemblance between the results indicates that the tool is useful. Keywords: Screen complexity measurements; Web page design; Complexity on screen

| How well the privacy policy follows a regulation is one of the current
concerns of the user. Such a task can be accomplished by directly querying the
policy statement with the regulation text. Automation of the process requires
an expressive meaning-based framework for Natural Language Processing (NLP).
This paper discusses the Ontological Semantics approach to the issue of
verifying compliance and illustrates the potential of utilizing the framework
in the domain of Privacy management for NLP-related tasks. As an example a
section from BCBS and corresponding HIPAA regulations are used. Keywords: Ontological Semantics approach; ontology; inference; Text-Meaning

| Evaluating Measurement Models for Web Purchasing Intention | | BIBA | Full-Text | 740-748 | |
| Bing-Yi Lin; Ping-Ju Wu; Chi-I Hsu | |||
| This study is mainly to evaluate measurement models for web purchasing intention, which reflects to a tendency of attitudes and behaviors toward the online purchasing behaviors. Four dimensions of web purchasing intention are proposed based on a literature review, including (1) Information Provision: product-related information that e-retailing users receive from the Internet; (2) Alternative Evaluation: issues that affect an individual's decision making when purchasing online; (3) Customer Service: services that e-retailing websites offer for customers in the e-transactions and post-sale process; (4) Price: the final dealing prices of products on e-retailing websites. This study developed a questionnaire and delivered to consumers with web purchasing experience. The method of Structural Equation Modeling (SEM) is adopted to verify the internal quality of the proposed measurement. | |||

| This paper describes web application for data analysis by means of
evidential dominance. Red Hat Linux 9, Apache, Tomcat, Java 2 Platform, and
Eclipse are used to this system as tools. In conventional system, Java for
Evidential Dominance is applied as Java servlet. Client accesses to the Web
Server to analyse data. Java for evidential dominance is started and
implemented on Web Server. The server processes and responses the result of
analysis to the client. The information of data is not remained in server. This
system not only responses the result of analysis to the client, but also save
the information of data in server. Evidential dominance is applied to decide
the priority relation of data which varies widely and have little amount of
data. Evidential dominance not only is effective to focus on one phase a lot of
alternatives, but also applies to decision making problem. Keywords: evidential dominance; data analysis; eclipse web tools platform; decision

| Usability of Electronic Medical Record System: An Application in Its Infancy with a Crying Need | | BIBAK | Full-Text | 759-765 | |
| Hal Miller-Jacobs; John B. Smelcer | |||
| There is almost universal agreement on the benefits of an Electronic Medical
Records (EMR) System, yet successful implementations are few. While EMR systems
focus on the important areas of functionality, interoperability and security,
the area of usability has been overlooked. No electronic medical records system
can be viable unless it addresses usability. We have had the opportunity to
work with several systems and have employed field data gathering, expert
reviews, usability testing and ScoreCarding to enhance the usability of EMR
systems. Unless usability becomes more widespread and is given a higher
priority, the benefits of an EMR system will remain elusive. Keywords: Usability; Electronic Medical Records; Electronic Health Records; field data

| Usability of User Agents for Privacy-Preference Specification | | BIBAK | Full-Text | 766-776 | |
| Robert W. Proctor; Kim-Phuong L. Vu; M. Athar Ali | |||
| The goal of this study was to determine (a) users' privacy concerns; (b)
whether these privacy concerns can be checked by an existing Web-based privacy
agent; and (c) whether users are able to easily specify their privacy
preferences using this agent. Users were able to configure the agent correctly
for about half of the desired privacy goals that could be checked by the agent.
Of more significance, users thought that they had configured the agent
successfully to achieve many privacy goals that cannot be accomplished with the
version tested. We also examined alternative interface layouts to ascertain
whether any of them allowed users to specify their preferences at a higher
success rate than the current interface. We discuss implications of our
findings for user agents designed to aid users' assessments as to whether a Web
site's stated privacy practices are consistent with the users' preferences. Keywords: privacy preferences; privacy policies; usability | |||
| Achieving Usability Within E-Government Web Sites Illustrated by a Case Study Evaluation | | BIBAK | Full-Text | 777-784 | |
| Basil Soufi; Martin Maguire | |||
| Local government in the UK has made progress towards the delivery of
services online. However individual local authorities do not necessarily have
the experience or infrastructure to develop web sites that are usable and that
can be maintained as content changes. This study used a three level model as a
heuristic tool to evaluate a case study e-government web site. While the
results were useful in proposing changes, barriers exist which slow down the
process of making the changes. The paper proposes strategies that may be
adopted to ease this process of web site development and change within local
government environments and elsewhere. Keywords: Web sites; heuristic evaluation; e-government; local government | |||
| A Conceptual Design for Children's WebOPAC Interface: Graphic Design Issues | | BIBAK | Full-Text | 785-791 | |
| Tengku Siti Meriam Tengku Wook; Siti Salwah Salim | |||
| Usability testing on Ilmu (i.e. WebOPAC for children) showed that poor
graphic design contributed the most to the usability problem. Three main issues
of graphic design are layout, use of colors and human visual perception. A
design approach is formulated in an effort to develop a conceptual design that
specifies children's requirements and preferences on graphic issues. This
involves two main activities which are identifying children's preferences on
graphic design and generating design ideas using participatory design method.
Four categories of requirements and preferences on graphic design are derived
from children. Each category is demonstrated by design ideas. All these
constitute towards the formulation of a conceptual design for children's
WebOPAC interface and become the basis for redesigning Ilmu's interface. Keywords: Graphic design; children's interface; conceptual design; participatory

| Examining User Privacy Practices While Shopping Online: What Are Users Looking for? | | BIBAK | Full-Text | 792-801 | |
| Kim-Phuong L. Vu; Fredrick P. Garcia; Deborah Nelson; John Sulaitis; Beth Creekmur; Vanessa Chambers; Robert W. Proctor | |||
| This study evaluated users' behaviors when performing inexpensive or
expensive e-commerce purchases on familiar and unfamiliar Web sites. Users were
more comfortable with making inexpensive than expensive purchases. They also
felt more secure and that their privacy was better protected when shopping with
a familiar Web site than an unfamiliar one, especially for expensive purchases.
For inexpensive purchases, if the price was "right", participants were willing
to purchase the product on unfamiliar Web sites. For expensive purchases,
though, the reputation of the organization hosting the Web site was the most
important factor. In both cases, privacy was a minor determinant for deciding
whether to make a purchase from a Web site. Only 20% of the users regularly
accessed the sites' privacy policies during their interactions with the sites.
Moreover, less than half of the participants even looked at privacy-policy
links during their interactions with the Web sites. Keywords: e-commerce; privacy policies; usability; eye-tracking | |||

| Kim-Phuong L. Vu; Vanessa Chambers; Fredrick P. Garcia; Beth Creekmur; John Sulaitis; Deborah Nelson; Russell Pierce; Robert W. Proctor | |||
| This study examined participants' comprehension of Web privacy policies when
the information from the policy had to be recalled from memory or when
participants were able to view the policy while searching for the answers to
specific questions. Eye-gaze data were analyzed to examine where users focus
their attention when reading privacy policies and searching for information in
them. Overall, participants showed poor comprehension of the information
conveyed in the privacy policies even though they were written at the
participants' level of education. When searching for information in the privacy
policies, participants relied on the listing of individual sections provided at
the beginning of a privacy policy, when available. When the listing of sections
was not available, participants skimmed the entire policy, examining the
headings and first few words of each paragraph to determine whether the
sections or paragraphs were likely to contain the information for which they
were searching. Keywords: reading comprehension; privacy policies; usability; eye-tracking | |||
| Using Long Term Memory for Bookmark Management | | BIBAK | Full-Text | 812-820 | |
| Ming-Jen Wang; Kuen-Meau Chen; Tee Koon Hau | |||
| When using the bookmark or "Favorites" function included with most web
browsers, it is difficult to retrieve a target bookmark if it is not properly
categorized or tagged with meaningful keywords. For this project, we propose
using a method of human-like long term memory (LTM) rather than directories or
keywords for searching and managing bookmark data. This experimental model
takes into account the user's browsing experience (i.e. the bookmark's added
date, number of visits, and last date visited) to create and manage bookmarks.
A pilot study of the model shows that the new system is significantly more
efficient at retrieving information from large collections of bookmark data. Keywords: Bookmark Management; Information Filtering; User Interface Design | |||
| Business Integration Using the Interdisciplinary Project Based Learning Model (IPBL) | | BIBAK | Full-Text | 823-833 | |
| Osama K. Alshara; Mohamed Ibrahim | |||
| This paper recognizes the need for new approaches in IT based education. Our
proposed model depends on two major concepts. The first is to believe in the
learning approach not the teaching approach that is widely used. Learning
delivery requires providers to alter their in-class approach and demands
students to be more independent learners. The second concept is the
interdisciplinary learning approach rather than the silo teaching model used
currently. For Example, software engineers will not be allowed to work in
isolation from the business people, the users, the client, etc. in the real
world. Therefore, their college education must qualify them, as much as
possible, to deal with the real world. This paper proposes an interdisciplinary
project based learning model focusing on collaborative learning (CL) and
Business Integration (BI) using the SEE [1] portal. This integral solution is
designed to overcome the teaching and silo models used currently. Keywords: Project based learning; integrated learning; interdisciplinary teams;

| Today's businesses increasingly rely on vast amount of information. Yet
effective use of information is becoming more and more difficult. This paper
describes a general purpose analytics solution, "Business Insights Workbench"
(BIW), which embeds two major classes of information analytics techniques and a
unique set of visualizations to mine the available information and uncover
critical business insights and enhance business performance. The two major
classes of analytics technologies include the "taxonomy" analysis and the
"relationship" analysis to facilitate understanding and detection of hidden
concepts and patterns buried in the information respectively. The BIW
technologies have been successfully applied in many application domains, e.g.,
Customer Relationship Management (CRM) for customer satisfaction analysis,
Intellectual Property (IP) for patent portfolio analysis and licensee
identification, and Healthcare Life-sciences (HCLS) for facilitating drug
discovery by identifying the relationships among chemicals, DNA, proteins,
drugs, and diseases. We show some BIW sample applications in this paper. Keywords: Information Mining; Human Interaction; Visualization | |||
| A Decision Making Model for the Taiwanese Shipping Logistics Company in China to Select the Container Distribution Center Location | | BIBA | Full-Text | 844-854 | |
| Chien-Chang Chou | |||
| The purpose of this paper is to propose a decision making model for the Taiwanese shipping logistics company in China to select the best container distribution center location. The representation of multiplication operation on fuzzy numbers is useful for the decision makers to solve the fuzzy multiple criteria decision making problems of container distribution center location selection. In the past, few papers discussed the representation of multiplication operation on multiple fuzzy numbers. Thus this paper first compute and obtain the representation of multiplication operation on multiple fuzzy numbers. Based on this representation, the decision maker can rank quickly the ordering of each alternative location and then select easily the best one. Finally, the representation of multiplication operation on multiple fuzzy numbers is applied to solve the fuzzy multiple criteria decision making problem of container distribution center location selection in China. | |||

| Daisuke Doyo; Katsuhiro Sakamoto; Katsuya Aoki | |||
| In recent years, needs for wide-ranging kaizen / improvements have arisen in relationships with suppliers and other transaction partners in response to rising demands including increases in profit and reductions in time. One of the technologies leading to kaizen / improvements is the application of servo-mechanism control to manage inventory ordering. It is thought that if this theory is applied to the overall supply chain, it may enable an optimization of the supply chain that fits the needs of modern society. This research proposes the prototype model of the supply chain model of the contemporary society applying the control theory, and the validity of that model is evaluated. | |||
| Understanding a Sense of Place in Collaborative Environments | | BIBAK | Full-Text | 863-872 | |
| Simon Foley | |||
| The article explores how mobile, nomadic and distributed workers develop a
sense of place to counter the lack of spatial determinants which increasingly
characterize contemporary work and lifestyles. When developing collaborative
technologies, designing for a sense of place becomes especially problematic
when spatial realities and empirical coordinates are absent or no longer take
precedence. What is lacking in the current knowledge is a coherent workplace
approach that can offer an overview of placeness, delineating not only the core
understandings of place but more importantly where these overlap and at times
conflict. The intention of this article, therefore, is to present an approach
that captures how key features of place as opposed to space, can be used as a
motivation for the design of collaborative technologies. Most importantly, this
approach must explain how the concept of place and its distinction from space
can provide new understandings of the public, private and permanent places of
work that help us to sustain productivity in the workplace. These at once
discrete and overlapping concepts help to frame the key research questions:
where is work? What constitutes a place of work? Who works there? Keywords: place; space; affordance; knowledge work; collaborative technologies;

| Hidenori Fujino; Hirotake Ishii; Hiroshi Shimoda | |||
| A routine work requires few skills, so employees can be skilled easily. Therefore, the productivity and the quality of work greatly depend on employees' work motivation. However, as a routine work is often not interesting to almost all employees originally, a method for promoting and keeping employees' work motivation is required for keeping or increasing the productivity and the quality of work. Therefore, the objective of this study is to develop the method for promoting employees' work motivation in a routine work especially with an affective interface and applying the persuasion technique. | |||

| This paper presents a case study on developing a smart user interface for
supporting the adjustment works on automated weighing machines of
computer-controlled multihead weighers. Based upon the theoretical and
practical framework of Vicente and Rasmussen's Ecological Interface Design
(EID), we clarified the functional structure of the work domain in terms of the
means-end relations, and visualized it on the screen displays to encourage the
human operator's "direct perception" of the meanings or values of his
practicable actions to those automated processes. Comparative experiments using
test subjects with a variety of skill levels confirmed the effectiveness of the
redesigned user interface that can facilitate unskilled operators appropriately
evaluating and effectively responding to their immediate work situations, and
that will take the place of the experts' knowledge and insights on the works as
one of the distributed resources for cognition. Keywords: Ecological Interface Design; Work Domain Analysis; factory automation;

| Case-Based Snow Clearance Directive Support System for Novice Directors | | BIBAK | Full-Text | 893-902 | |
| Yoshinori Ikeda; Yoshio Nakatani | |||
| Experts have issued directives for snow clearance in snowy regions. These
directives are implemented in accordance with the experience of the director in
charge, and snowplow drivers are reliant on directors to carry out their tasks
efficiently. However, many experienced directors will be retiring when they
reach retirement age in the next few years and their successors will be faced
with difficult circumstances because of a lack of training and experience. In
order to provide support to such neophyte directors, we propose a case-based
directive support system, which reuses past directive cases. Each such case
stores data on weather, snow, number of snowplows available, the time taken to
complete a snow clearance task and an evaluation of the tasks carried out by
the director. When a neophyte director specifies current task conditions, the
system searches and presents cases similar to the current conditions. When the
director selects the most similar case, the system estimates the time required
to complete the snow clearance task, based on the snow and road conditions. The
director can also manage the progress of snow clearance tasks with the system. Keywords: case-based reasoning; artificial intelligence; snow clearance | |||

| This research investigates the relationship between working conditions and
musculoskeletal disorders in an assembly facility. I believe that the physical
and psychosocial aspects of work have a significant influence on the individual
worker's health and well-being. The work organization at which I evaluated the
employee's health and well-being was at a large manufacturing assembly
facility. This research is based upon the Balance Theory Model of Smith &
Carayon-Sainfort [5, 6]. The overall aim of this research is to improve the
long term health and well being of worker's in a manufacturing assembly
facility. The overall purpose of this research is to try to identify the
stressful working condition and attempt to control it. By trying to control the
various musculoskeletal disorders in the work environment, you should also
attempt to reduce or eliminate the level of stress, and to try to reduce or
eliminate the level of strain. Keywords: Human Factors; Ergonomics; Musculoskeletal Disorders; Psychosocial; Balance

of customers. If a retail store is to sustain itself and continue developing,
it must search for the latent demands of customers and adapt itself to
accommodate those demands. A support system for store improvement capable of
viewing specific improvement plans will prove useful as a tool for improving
stores on a sustainable basis. In this research we develop a method for
generating effective store-improvement plans to accommodate actual customer
demands. The method employs both Text Mining and Conjoint Analysis techniques.
We also demonstrate a sequence and a test run of a prototype. Keywords: Customer-satisfaction measurement; Text Mining; Definition Method; Conjoint
Analysis; Store-improvement plan | |||
| Coping with Information Input Overload: User Interface Concepts for Industrial Process Control | | BIBA | Full-Text | 918-928 | |
| Tobias Komischke; Luis E. Herrera | |||
| Process control in control rooms is currently in a state of technological flux driven by recent developments in information technology. The continual integration of new control devices carries with it the risk of overburdening the human operators, with a major source of danger here being information input overload. This article addresses this phenomenon and the implications for user-centered process control. | |||
| Impact of E-Commerce Environment on Selection of Sales Methods Considering Delivery Lead Time of Goods | | BIBAK | Full-Text | 929-938 | |
| Etsuko Kusukawa; Shinji Masui; Ikuo Arizono | |||
| In this study, we discuss a brick-and-mortar sales (the existing sales
method through the sales channel 1) and an online sales under an e-commerce
environment (the sales channel 2). We focus on each differences of goods return
ratios and delivery lead-times to a customer through both sales channels for a
selling period. Concretely, we consider a parallel sales method that the sales
channel 2 is newly incorporated into the sales channel 1. In the parallel sales
method, a manufacturer incurs returns processing costs and fixed system
operational costs for both the sales channels. For an appropriate selection
ratio to the sales channel 2, the additional system operational costs in the
parallel sale method could be retrieved, and it could lead to improving the
profit to the manufacturer. Utility of the parallel sales method is
investigated from each difference of goods return rates and delivery lead-times
between both the sales channels by comparing the expected profit of the
manufacturer adopting the existing sales method with that adopting the parallel
sales method. Keywords: Sales method; e-commerce; inventory control; business model | |||

| Fumiaki Obayashi; Misa Kawauchi; Masaaki Terano; Kazuhiro Tomita; Yoko Hattori; Hiroshi Shimoda; Hirotake Ishii; Hidekazu Yoshikawa | |||
| A lighting control method has been proposed which adjusts the circadian rhythms of office workers and eliminates a decrease in the arousal level in the afternoon by exposing a high intensity of light in the morning in order to improve their productivity. As a result, it was found that the task performance of the CPTOP test under 2,100 lx was significantly higher than that under 700 lx and more than a 9% improvement of task performance was achieved. Furthermore, a demonstration experiment has been conducted in order to confirm the effectiveness of the proposed lighting control method in actual office rooms. As a result, it was confirmed that the performance of their accounting work was over 10% higher than under normal conditions. | |||
| The Inspiring Store: Decision Support System for Shopping Based on Individual Interests | | BIBA | Full-Text | 948-954 | |
| Akihiro Ogino; Sae-ueng Somkiat; Toshikazu Kato | |||
| This paper proposes a ubiquitous environment store, which is composed of cameras, sensors and displays, for supporting decision concerning commodities based on each customer's shopping interest. This store suggests that three analyzing views can be utilized to analyse relations between customers' interests and their behaviours towards commodities. This store collects data on the behaviour of each customer, who has agreed to be observed, and makes individual models, by analyzing collected data. This store also provides commodity information, which is decided by the individual's model, to each customer through a display, which is in front of this customer. Comparing this system to a non-system through a purchase experiment of clothes shows this effectiveness of this system. | |||
| A More Comprehensive Approach to Enhancing Business Process Efficiency | | BIBAK | Full-Text | 955-964 | |
| Seung-Hyun Rhee; Nam Wook Cho; Hyerim Bae | |||
| Whereas Business Process Management (BPM) systematically guides employee
participation in business processes, there has been little support, use or
development of user-friendly functions to improve the efficiency of those
processes. To enhance business process efficiency, it is necessary to provide
automatic rational task allocation and work-item importance prioritization, so
that task performers no longer need to be concerned with process performance.
In the context of BPM, two different perspectives, the Process Engine
Perspective (PEP) and the Task Performer Perspective (TPP), are considered.
Accordingly, we developed a comprehensive method that considers those two
perspectives, in combination rather than separately. We carried out simulation
experiments to show the combinational effect of the two phases. Keywords: Business Process Management; User-Oriented Support; Process Efficiency;

| Hiroshi Shimoda; Kyoko Ito; Yoko Hattori; Hirotake Ishii; Hidekazu Yoshikawa; Fumiaki Obayashi; Masaaki Terano | |||
| The authors have developed a performance test, CPTOP (Cognitive Performance Test of Productivity), which combines 11 basic task tests to evaluate intelligent abilities of office workers in order to quantitatively and objectively evaluate their productivity by controlling office environment. However, in the previous experiment, it was found that the results of CPTOP contain influences of learning effect and variation of difficulties depending on each problem set. In this study, therefore, subjective experiments have been conducted in order to compensate these influences and a correction method has been proposed. | |||
| Information on the Causal Relationship Between Store kaizen and Store Features That Attract Customers by Covariance Structural Analysis | | BIBAK | Full-Text | 973-982 | |
| Yumiko Taguchi; Yasushi Akiyama; Tsutomu Tabe | |||
| This research has two objectives: first, to develop a method to
quantitatively clarify the causal relationship between store improvements
(store kaizen) and store features that attract customers; second, to verify the
effectiveness of the method developed. The results of this research confirm two
points. (1) The causal relationship was quantitatively clarified through the
use of a covariance structural analysis, and the degree of the relationship
between the store features that attract customers and store kaizen could be
understood. (2) The proposed methodology has proven to be useful in an actual
store improvement activity. The owner of the store studied in the investigation
commented, "It is very important to set up a hypothesis when seeking an
improvement. This research provides a helpful framework for doing so." Keywords: store features that attract customers; store kaizen; causal relationship;

| Methodology for Constructing a Prototype Site for Finding Employment SPI Measures Using Mobile Phones | | BIBAK | Full-Text | 983-993 | |
| Shinsuke Wakita; Michiko Anse; Tsutomu Tabe | |||
| The written examination for job hunters in Japan is an important examination
that cannot be skirted as the first step in the hunt for employment. However,
there is no environment that can be studied using easy methods (mobile phones,
etc.). In this research we clarify a methodology for constructing a prototype
system for finding employment SPI measures. After constructing a prototype, we
examine the effectiveness of the methodology. We use answer formats to achieve
two purposes. (1) We clarified an answer format that can be efficiently studied
through an experiment in 'no space' in order to produce a measure site that can
be efficiently studied in little time. (2) We constructed a prototype for
selecting answer formats in order to examine whether the prototype can be used
to select the following two formats on a mobile phone: first, "the word, the
meaning of the word, and an example of the word in use"; second, "the word, an
explanation of the word, an example of the word in use, and the meaning of the
word." (3) The test-takers studied the constructed prototype on mobile phones,
then our group examined the effectiveness of the prototype based on the
questionnaire results. The results indicate that the form can be efficiently
studied. Thus, we can conclude that the prototype constructed can be used to
select the following two answer formats: "the word, the meaning of the word,
and an example of the word in use" and "the word, an explanation of the word,
an example of the word in use, and the meaning of the word". Keywords: e-learning; mobile phone; answer presentation form; problem display form | |||
| Production Information Management Interface for Operators in Production Process | | BIBAK | Full-Text | 994-1003 | |
| Tomonori Yuasa; Yoshihisa Aizu | |||
| The AMPAC 1, 2, 3 proposes a simple and unified format to describe
parameters of the printing production process such as design, press and
bookbinding. The database described by the format can be used commonly in any
processes connected by the network production system, since the description
accepts any parameters in any processes. A print production system assisted by
computers should be very helpful to boot it after altering a parameter of the
process, since preparation for starting up a printing machine requires abundant
knowledge and wisdom. This paper gives details of the knowledge and wisdom
stored in the AMPAC database used for booting the printing machine. Parameter
data stored in the AMPAC database can easily be searched and found all of
resetting targets in the printing machine when a parameter in the process is
changed. This advantage comes from the fact that each parameter of the machine
setting can be connected with the related parameters in this database. Keywords: AMPAC; Database; Standard; Network; Printing; Workflow | |||

| The overall objective of this research project is the development and evaluation of a flexible and cooperative management system within SME based production networks for the ramp-up process. Inter-organizational processes of six previous ramp ups were analyzed and documented in flow charts. High-level executives and domain-experts of the production nets developed in moderated focus-groups standardized steps and phases of the ramp-up processes and agreed on one common reference workflow. The reference workflow is the basis for the further development of the inter-organizational management of virtual project teams supported by an IT-assisted workflow management system. | |||

| The object of this research is to build supporting systems for disaster
victims, especially for the elderly. These systems are considering as follows:
support the people who belong to the specific area, work on the initial stage
of disasters. By using these systems, the people in the area can be easy to
refuge and to communicate each other. Therefore we suggest several ideas to
build systems. And we focus on the system which concerns the elder's action to
refuge and demands of the elderly in such situations. Then we aim at designing
concrete functions based on these ideas. Keywords: earthquakes; systems; the elderly; the initial stage; the characteristics of

| Dementia occurs in every country of the world, especially in developed
nations. Since such spatially and cognitive impaired people lack the ability to
grasp positional relationship between landmarks, we have developed a walk
navigation system using photographs of landmarks to benefit them and their
families. Our system provides a photograph of the next target landmark to the
mobile devices of cognitive impaired people. It can also identify points where
cognitive impaired are likely to get lost. Our system can also support such
tasks as taking tickets by photographs and animations. Keywords: photograph; spatial cognitive ability; landmark; mobile device | |||

| Rainer Koch; Rüdiger Harnasch; Bo-Sik Lee; Jens Pottebaum | |||
| The range of tasks for Search And Rescue (SAR) services is very comprehensive and requires extensive experience in addition to detailed knowledge. Actual and extended incident data, tactical information and technical knowledge are significant issues in this field. Within research projects information systems are designed to provide relevant information with the required/desired detail depth to the individual user groups. Mobile information processing instruments in combination with an internet based access to a modular knowledge database are predestined to improve the handling of emergencies as well as the data management for operation controls and fire-fighting forces. Emerging data transfer technologies like UMTS as well as WLAN are applied in order to access the database independent of the location. Semantic methods provide new possibilities to interlink information which accelerates the data preparation and retrieval. This paper describes the information and knowledge availability and adaptation. | |||
| Health Risk Estimation of Dichlorobenzene Exposure Workers by Using Computer Models | | BIBAK | Full-Text | 1060-1066 | |
| Pei-Shan Liu; Ren-Ming Yang; Yin-Mei Chiung; Chung-Yong Liu | |||
| 1,4-Dichlorobenzene (DCB), widely used as a moth repellent and a space
deodorant, is one kind of chlorobenzene that is classified by the International
Agency for Research on Cancer among chemicals possibly carcinogenic to humans
on the basis of a sufficient evidence for carcinogenicity to rodents. DCB has
been found to cause renal tubular-cell adenocarcinomas in rats and
hepatocellular carcinomas in mice but without their clastogenic and genotoxic
effects. In this study, we investigated the health risk of DCB workers from
three steps. Firstly, we investigated the cytotoxicity of 1,4-dichlorobenzene
and its metabolite 2,5-dichlorophenol in human lymphoma Jurkat cells, human
colon adenocarcinoma cells and human hepatocellular carcinoma cells. The LD50
of DCB were 1.34 mM, 5 mM and 2 mM in Human lymphoma Jurkat cells, human colon
adenocarcinoma cells and human hepatocellular carcinoma cells respectively. DCB
was found to cause apoptosis itself and reduced the staurosporine-induced
apoptosis in all three cells. Secondly, works in four factories were
investigated to examine their blood cells. Two items, their apoptosis rate and
their anti-apoptosis rate, were investigated on the work's blood. In an
investigation on Dec, 2004, we found a significant higher apoptosis rate of
exposure workers comparing with non-exposure workers. The blood cells of
workers were significantly resistant to the staurosporine-induced apoptosis. In
the other three investigations in 2005, we found similar phenomenon that the
blood cells of exposure workers had higher apoptosis rate and higher resistant
rate to staurosporine-induced apoptosis. Thirdly, the DCB content in the urine
and blood of workers were analyzed. Based on the low to high level of DCB
content, the workers were grouped into 10 degrees. The correlation of the level
of DCB and apoptosis rate and anti apoptosis rate was analyzed by Pearson
Correlation Program. The apoptosis rate and anti-apoptosis rate of worker's
blood were both significant negatively correlated with the DCB content in their
urine and air. Based on this computer program analysis, we suggest that the
exposure of DCB induced significant changes of the blood cell of exposure
workers and need to be concerned. Keywords: 1 and 4-dichlorobenzene; apoptosis; anti-apoptosis; staurosporine; Pearson

| Economic Assessment of Industrial Accidents Caused by Abnormal Behaviors | | BIBAK | Full-Text | 1067-1071 | |
| Hunszu Liu | |||
| The economic assessment of industrial accidents caused by abnormal behaviors
can not only improve the risk assessment results but also serve as a crucial
criterion for prioritizing the correction plans. Three stages of works are
designed to derive the loss figures from assessing the standard operation
procedure. The objective of stage one is to identify potential abnormal
behaviors through analysis of activities. The objective of stage 2 is to
identify cost types initiated by different accident losses. The objective of
stage 3 is to establish the accident cost bank through analyzing the historical
accident data. Two industrial cases, including one semiconductor and one steel
company, were studies to demonstrate the feasibility of this approach in both
high-tech and traditional industry. This study proposes a framework to develop
abnormal behavior identification and cost estimation model. Keywords: abnormal behaviors; risk assessment; safety economics | |||
| A Real-Time GPU-Based Wall Detection Algorithm for Mapping and Navigation in Indoor Environments | | BIBA | Full-Text | 1072-1077 | |
| Hadi Moradi; Eun Kwon; Dae Neung Sohn; JungHyun Han | |||
| In robotic applications, there is a growing trend for developing human-like real-time interaction capabilities. A good example can be found in Simultaneous localization and mapping technique, where a robot or an autonomous vehicle builds up a map within an unknown environment while at the same time keeping track of its current position. Especially in indoor environments, wall detection is often a critical part of SLAM: it plays a key role in scene interpretation and 3D workspace modeling. Further, it also reduces the size of the map. This paper presents an effective and real-time approach for detecting walls in indoor environment using GPU (graphics processing unit). The experimental results show the feasibility of using GPU as a coprocessor in robotic applications. | |||
| Development of Cooperative Building Controller for Energy Saving and Comfortable Environment | | BIBAK | Full-Text | 1078-1087 | |
| Yoshifumi Murakami; Masaaki Terano; Fumiaki Obayashi; Mutuo Honma | |||
| The purpose of automatic controllers for building services (air conditioning
system, lighting and blinds system) is to save energy in the whole building
while keeping occupants' comfort. Nevertheless, most of automatic controllers
don't optimally operate from the viewpoint of total energy efficiency and
occupants' satisfactions. The main reason is that each controller operates,
neglecting states of other controllers and therefore, control point of each
controller always doesn't correspond to best control point in the whole
building system. In this study, we propose an innovative controller that
communicates with other controllers to control building equipments optimally
from the viewpoint of total energy efficiency and occupants' satisfactions. The
developed controller functions as an agent in the control system, which can
voluntarily collect available information from other controllers and decide set
points to enhance total efficiency in cooperation with one another. Therefore,
this controller is called as "cooperative controller". Several types of
cooperative controllers have been developed and experimentally applied to an
actual building located in Japan (Sogo et. al. 2002, Honma et. al. 2002, Terano
et. al. 2002). In this paper, cooperative control using daylight, major example
in series of cooperative control system, is reported. Daylight is useful to
reduce energy consumption of lighting, however, it has not been widely used.
The main reason is that as incoming daylight has complex effects on thermal and
visual environment, it is difficult to optimally control amount of daylight. To
solve this problem, we propose cooperative control system that can control
amount of daylight effectively to optimize total energy efficiency and
occupants' comfort. A series of numerical experiments was conducted to confirm
effect of cooperative control system on improvement of total energy efficiency
and indoor environment. The results showed that this cooperative control system
could save energy use rate of almost 10% compared with no cooperative control
system. In addition, in order to use in practice, cooperative controller is
designed to apply an actual building easily and keep stability even in the
other controllers' troubles. Keywords: Energy saving; Cooperative control; Venetian blind | |||

| A methodological approach is presented for the human-centered development of
Advanced Driver Assistance Systems (ADAS). A procedure has been developed for
the objective evaluation of potential impacts of ADAS usage on traffic safety.
The procedure is based on the observation and analysis of the emergence resp.
avoidance of driving errors (inadequate speed, insufficient safe distance,
etc.) in conjunction with the usage of ADAS. Driving errors are assumed to
occur by the coaction of functional ADAS features, the situational context and
(psychological) behavioral backgrounds. The applicability of the approach is
examplified with a simulated ADAS. Keywords: Advanced driver assistance systems; traffic safety; driving errors; risk

| As Augmented Reality Navigation systems receive increasing attention as the
next generation navigation systems, the importance of the layout of the
elements and searching for the appropriate level of information cannot be
overstated. Due to this, a series of experiments of usability tests had been
designed. According to the experiments, the results for the screen arrangement
showed that the MBN screen displayed on the left and the ARN screen on the
right was preferred the most while the results for changing lanes showed that
displaying information directly on the road and highlighting the path was the
best method. As for switching direction, using the upper icons and displaying
information directly on the road was preferred. The adequate amount of
information was found out to be an average of 3 POI with 20pt font sizes for
ARN displays and 10 POI with 18pt font sizes for MBN displays. Lastly, the
Eye-tracking experiments showed that the ARN screen was viewed more often with
a ratio of 7:3. Keywords: Augmented Reality; vehicle navigation; disposition of information; adequate

| Validation of Critical Parameters for Predictive Evaluation of Notification System in Avionics Interfaces | | BIBAK | Full-Text | 1109-1118 | |
| Miguel A. Sánchez-Puebla; Ignacio Aedo; Paloma Díaz | |||
| The evaluation of notification systems is rare in critical systems. The only
available experiences are based on empirical data on costly simulated
environments and the subjective follow-up of some guidebooks probed by the
experience. In case of absence of performance requirements, critical parameters
can provide quantitative measures that may be used to determine the overall
usability of interfaces that continuously present precious information (id est.
Notification Systems) in Avionics (NSA) and should be validated before use to
improve the confidence level in the measurement unit. In this paper, we
introduce a set of critical parameters that could be used for usability
evaluation of NSA's interfaces. A process for a formal validation is described
and results of the applicability of these parameters to the real NSA interface
of A400M's power plant are presented. Keywords: Human Factors; Critical Parameters; Notification Systems; Predictive

| TDARS, a Fusion Based AR System for Machine Readable Travel Documents | | BIBAK | Full-Text | 1129-1138 | |
| Yu Wu; Ling Xue; Chao Li; Zhang Xiong | |||
| A fuzzy set-based AR (Automatic Recognition) system named TDARS for machine
readable travel documents (MRTDs) is designed and implemented for speeding up
customs clearance. The system consists of three parts: text feature extraction,
facial feature extraction and identity matching. Text feature extraction takes
charge of locating machine readable zone (MRZ) and extracts text features
automatically. Facial feature extraction focuses on locating the front face
photo (FFP) in the MRTD and extracting the facial features of the MRTD
possessor. Identity matching compares text and facial features with feature
data in the Terrorist Database (TDB) respectively and fuses the matching
results of text and facial features in the decision-making level using a fuzzy
set based algorithm. Experimental results show that both the correct acceptance
and refusal rates of the TDARS are over 90%, which evidently exceed those of
the existing recognition systems that extract text features solely. Keywords: information fusion; fuzzy integration; character recognition; face
