본 연구에서는 웹 기반 멀티미디어 공동 작업 환경에서의 다중 세션을 잘 유지하기 위하여 웹 노트 오류 제어를 위한 관리기에 대해서 기술한다. 웹 기반 멀티미디어 공동 작업 환경은 멀티미디어 협력 작업에 웹의 동기화 기술을 확장한 웹 노트, 즉 복제형 구조에 기반을 둔 응용 공유의 동작 원리를 이용하여 동기화를 수행할 수 있는 환경을 의미한다. 각 세션의 생성에 따라 서비스 제공자는 생성된 서비스 제공자 인스턴스를 생성하게 되고 이 인스턴스는 부모인 서비스 제공자의 자원을 이용하여 다수 세션을 지원한다. 이러한 환경에서의 웹 노트 오류 제어 시스템을 기술한다.

Web 2.0 is changing the paradigm of using the Internet which is affecting the e-learning paradigm. E-learning 2.0 based on the Web 2.0 has a bottom-up approach which learners work on content with social networking and collaboration in their own cyberspace. Second Life is presented as a new e-learning environment. - Flexibility, - Strong social networking, - Residents’ creative activities of Second Life ⇨ Unlimited potential to educators Second Life is a classroom built in 3D cyber space.

The purpose of this study is to compare the characteristics of research collaborations in the field of LIS. While there are several studies under the unit of analysis of country, there are only a few studies under the unit of analysis of institution in LIS field. For this analysis, we selected eight journals in the KCI (Korea Citation Index) web site, which correspond to the field of LIS through subject classification. The collaborative indices, Collaborative Coefficient, Co-Authorship Index, Local Collaborative Index (LCI), Domestic Collaborative Index (DCI) allowed us to comparatively analyze institutional collaboration patterns in LIS field. In the case of Chung-Ang University, Yonsei University, and Ewha Womans University, collaborative research among professors, graduate students, and professors reflected the fact that collaborations among universities are often performed with professors. In the case of KISTI, which showed a very high index value, the characteristics of project-based research are reflected in the research collaboration pattern.

Recently, the advent of World-Wide-Web(WWW) and the explosive popularity of the Internet gave birth to collaborative applications which were enabled by computers and networks as their primary media. The progress of 3D computer graphics enabled collaborative application with 3D virtual environments or distributed virtual environments. In this paper, we explain our implementation of the Share collaboration engine which is for collaboration applications based on a distributed virtual environment. We introduce Virtual Architectural Engineering 2000 (VAE2000) that is our pilot application implemented with the Share collaboration engine. The Share collaboration engine proposes a new Share network architecture for management of participants, and it provides some synchronization methods for 3D objects in virtual collaboration. VAE2000 is an experimental application that tries to prevent wastes of human, material and time resources in networked virtual collaboration.

In this study, national web archiving cases were reviewed and interface types and characteristics were examined. Five interface categories and fourteen evaluation criteria were selected. As for the OASIS, Korean national web archiving project, functions of retrieval interface and user support interface were insufficient and need to be reinforced. Other recommended improvement plans were; diversifications of the subject area of web contents, sharing the web acquisition, make up the special collection, visualization of archiving time and trends, systematic performance of the archiving strategy, and active collaboration with international organization.

With rapid development of information and communication technologies, open collaboration can be eased through the Internet. Open source software, as a representative area of open collaboration, is developed and adopted to various fields. In this research, based on organizational learning theory, we examine the impacts of exploration and exploitation on innovation performance in open source software development projects. We define knowledge exploration as a number of developers from outside organization and knowledge exploitation as the ratio of member of an organization who participated in an open source software project managed by the organization. For analysis, we collect data of 4794 projects from github which is a representative open source software development platform using Web crawler developed by Python. As a result, we find that excessive exploration has curvilinear (invers U-shape) relationship on project performance. On the other hand, exploitation with enough external developers will positively impact on project performance.

Multimedia systems design generally requires a collaborative effort from a group of designers with a variety of backgrounds and tasks, such as content experts, instructional designers, media specialists, users, and so forth. The fact that the designers have totally different backgrounds and tasks may hinder their collaboration. This research develops a collaborative design tool for multimedia systems design, called the Designer's Cafe, with which multimedia designers can share their design knowledge on the Web freely. Designer's Cafe consists of three intelligent agents that are designed for supporting collaboration activities of multimedia designers. The intelligent agents are implemented by using JAVA SCRIPT and COLD FUSION. By using the tool, designers create, revise, and share their knowledge/ideas in very structured ways. The structured design process might enhance the collaboration activities of designers while designing a multimedia system within a virtual working space.

For joint value creation, collaboration among different interested parties is vital and should be supported by information technology. Currently, both government and private companies have launched websites to collect ideas. However, the information poor, including the visually disabled, have difficulty in gaining access to those websites. Therefore, the aim of this paper is to evaluate the level of web accessibility to websites, operated by companies or the government, for idea proposals. According to the automatic assessments, regarding proposal specific websites, 77%, 69% of the websites operated by the government and 41%, 44% of those operated by private companies were extremely inadequate. According to the expert's assessments, regarding proposal specific websites, 67%, 52% of the websites operated by the government and 39%, 26% of those operated by private companies were extremely inadequate in their level of accessibility. A range of policies should be prepared to improve web accessibility.

The rapid progress of the Internet and network is affecting the engineering design environment as well as business that use Web technologies to enhance their competitive edge. In product development, experts and organization who take part in the design process are often geographically dispersed. Furthermore, different divisions and business often have heterogeneous CAD/CAE systems and methods for expressing product data, and addressing this heterogeneity creates additional costs and increases development time. Managing distributed CAD, CAE and other related systems in an organic and holistic manner from the initial stages of product development is imperative to ensure successful collaboration in the design process. Therefore, this study suggests a Web-based MDO framework to support interfacing and collective use of design and analysis tools.

This paper introduces a Web-based vibration analysis system for rotary-type refrigerator compressors. Concern for vibration reduction in compressors has been growing for many years. What is important in vibration reduction is to easily predict the vibration without using a physical compressor. The dynamic model of the compressor is represented as a multi-body dynamic system. Solving the dynamic model is run on a high-performance server. The interfaces of the system are accessible via Web browsers, such as Netscape or Explorer. Anyone who wants to analyze the vibration of the rotary compressor or share the results data can access the system over the Internet regardless of their OS, platform. or location.
