This paper explains the design and implementation of the EC_NH. EC_NH is a system that is suitable for detecting, sharing and recovering software error based on multimedia CSCW(Computer Supportes Cooperated Work). With error sharing system, a group cooperating users can share error applications. From the perspective of multimedia collaborative environment, an error application becomes another interactive presentation error is shared with participants engaged in a cooperative work. Our Digital Carousel enables user to share media objects through media synchronization mechanism. We implemented the Digital Carousel so that the users participated in collaborative work may refer shared media or error objects as the same view to others.

This paper suggested a web based error manager for societal security service. This is a system that is suitable for detecting, sharing and recovering software error based on multimedia CSCW(Computer Supportes Cooperated Work). With error sharing system, a group cooperating users can share error applications. Our a web based error manager for societal security service enables user to share error objects through interaction awareness. This method has a file sharing, a window copy, a window overlay, or a window sharing. We implemented the web based error manager for societal security service so that the users participated in collaborative work may refer shared error objects as the same view to others.

As computer systems and communication technologies develop rapidly, CSCW(Computer Supported Collaborative Work) system appears nowadays, through which it is available to work on virtual space without any restriction of time and place. Most of CWCS systems depend on a special network and groupware. The systems of graphics and CAD are not so many because they are specified by hardware and application software. We propose a Web-based collaborative CAD system which is independent from any platforms, and develop a 3D solid modeler in the system. This system can be worked in the environment of Client/Server architecture. Clients connect to the design server through Java applet on WWW. The server is implemented by Java application.

In distributed office, the pairs can program together using a distributed pair programming system. Many CSCW tools featuring remote screen sharing function have insufficient usability, accessibility to introduce many developers to distributed pair programming. In this paper, we suggest a distributed pair programming system based on IDE, which many developers will accept and use easily. We have do#eloped a user scenario and GUI of the system, making distributed pair programming easier and designed with high extensibility by adapting design patterns and implemented in Java language. Our findings will be of significant help to developers dealing with implementation of distributed pair programming function into some commercial IDE.

CSCW 시스템은 효율적인 공동작업의 인지를 위해 텔리포인팅, 스냅샷, 문서/프로젝트 추적등과 같은 기능들을 제공한다. 이 중 텔리포인팅은 지역 시스템의 공유윈도우에서 텔리포인터를 통해 발생한 이벤트를 원격지 시스템의 공유윈도우에 동기적으로 표현하는 기법이다. 텔리포인팅은 여러 연구들에서 응용된 바 있으나, 텔리포인팅의 프로토콜에 관한 연구는 미흡하다. 본 논문은 RTP(Real-Time Transport Protocol) 기반의 텔리포인팅을 위한 RTP 페이로드 형식을 정의한다.

The current network environment is composed of heterogeneous H/W and S/W resources. Integrating CSCW applications in such heterogeneous environments is highly complex. This paper describes the design and implementation of ASS (application sharing server) which supprot sharing of a single application between different operating systems. The ASS supports cooperative work among user group using its own window system (X-windwo or MS-windwos). We adopted improved managing heavy-weight data. ASS also provides development environment for vaious groupware application.

3차원 공간에서 항행기법을 이용한 사용자 인터페이스는 정보의 시각화를 통한 편리성과 연속적인 제어를 통한 자연스런 대화가 가능하다는 장점이 있다. 또한, 응용범위와 표현력의 증가, 사용자의 이해를 증진시킬수 있는 점등 잇점이 많다. 하지만 개념의 미확립. 구현상의 복잡성 등의 문제점으로 인해 아직까지는 개발이 부진한 상태에 있다. 본 논문에서는 이런 3차원 항행기법을 그룹웨어 응용프로그램이 요구하는 사용자관리, 도메인 관리 및 세션관리에 적용해 봄으로써 공간상에 시각정보를 나타내는 방법에 관한 구체적인 면을 설명한다.

To support cooperative work in various scenes by computer systems, functions of sharing personalization, observation and control are needed. Especially, in advanced cooperative work, people have various position so that sometimes one person needs to restrict behavior of another. In this paper, we describe representation of access restriction of hypermedia system, which is framework of CSCW(Computer-Supported Cooperative Works) system we developed and propose a way to go on working cooperatively with people, restricting others.
