본 논문에서는 웹 기반의 멀티미디어 공동 작업 환경에서의 오류 공유 시스템에 대하여 제안한다. 오류 공유 시스템은 윈도우 방식을 사용하고 응용 및 오류 공유 구조로는 분산 복제형 구조(CARV)이다. 분산 복제형 구조는 중앙 집중형 구조와 복제형 구조 두개의 장점을 취합한 형태이지만 복제형 구조처럼 완전한 대칭적인 구조를 가지고 있지는 않다. 감지된 오류는 웹 상의 오류 공유 시스템을 이용하여 신속히 전달하여서 오류를 공동으로 공유할 수 있게 하고 신속히 복구할 수 있도록 한다.

본 연구에서는 산업 안전 서비스를 위한 IP-USN 기반의 멀티미디어 공동작업 환경에서 응용 소프트웨어와 미디어 등의 프로세스(process) 요소들에 대한 오류를 미리 감지하여 오류 공유 시스템을 이용하여 신속하고 정확하게 전달하여서 복구하는데 빠르게 대처할 수 있는 시스템을 제안한다. 감지된 오류는 오류 공유 시스템을 이용하여 공동 작업을 하는 다른 사용자들에게 신속히 전달하여서 오류 발생 인식을 공동으로 대처할 수 있도록 한다. 본 논문에서 제안한 오류 공유 시스템은 산업 안전 서비스를 위한 IPUSN 기반의 LAN 및 WAN 환경에서 응용 프로그램에서의 오류를 다수의 사용자가 공유하도록 지원한다. 특히 기존의 방법과는 달리 참여자의 수에 관계없이 일정한 전송률과 동일한 응답 시간을 보장함으로써 동시에 모든 참여자들이 같은 결과의 오류를 인식하게 되며 사용자의 수의 증가에 따른 영향을 적게 받는다.

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.

This paper describes the design overview of shared file system $SANique^{TM}$ and proposes the method for detection of failure node and recovery management algorithm. We also illustrate the characteristics and system architecture of shared file system based on SAN. In order to provide uninterrupted service, the detection and recovery methods are proposed under the all possible system failures and natural disasters. The various kinds of system failures and disasters are characterized and then the detection and recovery method are proposed in each disconnected computing node group.

This paper explains the design and implementation of the ESA(Error Sharing Agent). ESA is a system that is suitable for detecting, sharing and recovering software error based on multimedia CSCW(Computer Supportes Cooperated Work). This system consists of an ED, ES, and ER. ED detects an error by hooking techniques. ES is an agent which is an error sharing system for distributed multimedia collaboration environment 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. We propose how an error application can be treated as 'media' in a multimedia collaborative environment.

We propose ESS_WMCE. This paper explains the design and implementation of the EDSS running on ESS_WMCE. EDSS is a synchronization error control system for web based multimedia collaboration environment. We have an error detection approach by using hooking method. The technique of an error transmission is a mended model of utilizing an application sharing system. DOORAE is a good framework model for supporting development on application for computer supported cooperated works. It has primitive service functions. Service functions are implemented with an object oriented concept. It is a system that is suitable for detecting and sharing a software error rapidly occurring on web based multimedia collaboration environment by using software techniques. It is able to share an error as well as providing URL synchronization to access shared objects. When an error occurs, this system detects an error by using hooking methods in MS-Windows API(Application Program Interface) function. If an error is found, it is able to provide an error sharing to access shared objects.

For effective information sharing, data provenance semantics need to be managed effectively. Based on a scheme to represent data provenance semantics, we propose a model to calculate information sharing costs. Information sharing costs are derived from probabilities of type I and type II errors that occur in organizational information sharing, costs related to these errors, and information sharing distances between organizational units which are determined by information sharing workflows. We apply the model to various types of information sharing workflows including departmental information systems, hierarchical information systems, a hub and a stand-alone system. The calculated information sharing costs show that the hub with data standardization is best in information sharing; however without standardization its information sharing cost deteriorates to that of a departmental information system. And, any information sharing workflow is better than a stand-alone system. It is proved that the model is useful in analyzing effectiveness of information sharing workflows and their characteristics.

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 explains the design and implementation of the EC_DXS(Error Control in Digital Carousel System). EC_DCS 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 me. applications. From the perspective of multimedia collaborative environment, an error application becomes another interactive presentation error is shared with participant engaged in a cooperative work.
