The purpose of our study is to develop a prototype groupware environment that addresses the different phases of meetings as well as to provide for customizable meetings. We describe several components that can be used to support the entire life-cycle of a distributed meeting. Our design is based on the premise that meetings are comprised of three stages: pre-meeting setup, during meeting activities, and post-meeting teardown. Additionally, meetings are individual, each requiring a different set of tools and applications. Our protype contains six components to support these stages. These components are electronic mail, bulletin board, organizer, agendas, virtual meeting room, and storyboard viewer.

2000 년대 초반부터 글로벌화에 따라 화상회의 시스템이 정부와 기업에 중요한 업무지원도구로 확산이 되고 있다. 그 동안은 화상회의는 기업이라는 제한된 울타리에서 1:1 또는 다자간의 회의를 위한 도구로 만족을 하였지만 점차 화상회의를 상업용, 가정용으로 적극적인 활용을 모색하는 추세이다. 또한 기존의 인터넷, 모바일 등을 이용한 비즈니스 모델은 발전의 한계점에 도달하였으며, 고객들의 새로운 요구에 부응하기 위하여는 화상회의를 이용한 비즈니스 모델의 출현이 요구되는 시점이다. 본 연구에서는 화상회의를 이용한 비즈니스의 확산을 위하여, 화상회의 비즈니스 모델의 구조를 설계하였다. 또한 설계를 적용할 수 있는 환경연구로서, e-커머스에 대응한 화상회의 상거래, 즉 v-커머스를 지향한 기술 및 서비스 구성, 비즈니스 모델의 유형과 고객가치속성, 모델의 구성요소, 적용사례 등을 제시하였다.

Since wide display devices have recently become popular for communication activity, it is desirable for effective communication to share those displays in an efficient way. VNC(Virtual Network Computing) is a desktop sharing software, which transmits the desktop screen and the related events to other computers on different places. So, through VNC, it is possible for more than two users to share the same desktop screen at the same time. But it is very cumbersome to share wide display devices through the functions currently supported by VNC. In this paper, we describe the development of CoDisplay which is a VNC-based conference tool for efficient sharing of a wide display device. Conference participants connect to the wide display device through the associated network address, and transmit their desktop screen to the device. The control functions for the participants support the division of the display screen for multiple desktop screens and the switchover of desktop screens.

A video conferencing system provides sharing the conference environment for geographically dispersed computer users who use the audio and video information. But the conventional video conferencing systems have some problems which are dependent on specific software and/or hardware and bound the certain platform and network environment. Furthermore the participants must know the information about other participants before joining the conference session and they have to use the same video conferencing system. This paper describes design and implementation of the video conferencing system on the WWW to solve the mentioned problems. The conference applications are transmitted from a WWW server and executed in the participants Web browsers. The participant can carry out conference services by using only the web browser. The WWW server takes charge of conferencing management including the information related to the participants and provides supported conference tools such as whiteboard, chatting and multimedia controls. Therefore the participants can easily join the conference sessions and perform conference working regardless of network connection situations. We used the Java to implement the seamless session connections and interaction between the conference participants which are the most important when implementing the video conferencing system on the WWW and used the ActiveX technology about the audio and video controls to make it easy the hardware control.

The purpose of the study is to develop a questionnaire that examines unskeptical attitudes in scientific inquiry context. The questionnaire items were developed through literature research, expert review, and statistical analyses for validity and the differences in scores were identified by gender and tracks. A total of 363 high school students participated in the study. To explore the validity evidence of items, the Rasch analysis and the reliability of internal consistency were performed, and the two-way ANOVA was performed to compare the scores of the unskeptical attitudes between gender and academic track. Self-reporting and Likert-scaling 23 items were developed to measure unskeptical attitudes in scientific inquiry context. The items were developed in the sub-domain of scientific inquiry: 'questioning and hypothesis generating,' 'experiment designing,' and 'explaining and interpreting.' Second, the validity and reliability of the unskeptical were identified in a rigorous method. The validity of items were identified by multi-dimensional partial score model analysis through the Rasch model, and all 23 items were found to be fit to model. Various reliability evidences were also found to be appropriate. It was found that there were no significant differences of unskeptical attitude score between the gender and academic track except one comparison. The developed questionnaire could be used to check an unskeptical attitude in the course of scientific inquiry and to compare the effects of scientific inquiry classes.

In the paper, we describe the IPv6-based multicast videoconferencing tool and it's experimental results by using TEM (TransEurasia Information Network) which is connected between Korea and Europe recently. And we explain the efficient configuration method of IPv6 multicast as well as IPv6 configured tunneling in between Korea and Europe.

현대 사회에서는 의사 결정을 위해 다양한 도구가 사용되고 있다. 대규모로 진행되는 토의나 토론에서는 데이터를 분석하는데 많은 비용과 시간이 소모되고 있다. 회의록 요약시스템은 기존 문서처리방법을 자동화하여 인건비 절감과 처리시간을 단축하는 긍정적 효과를 기대하고 있다. 본 논문은 기존에 수작업으로 진행되었던 과정을 보다 효과적으로 운영할 수 있도록 회의록 요약시스템을 설계하고 구현한다. 대규모 토론이나 토의에서도 요약시스템 통해 대표의견을 제시받아 정확한 의사결정을 하여 시간절약과 비용절감 효과를 기대한다.
