The web-based group collaborative systems are emerging as enterprise-wide information systems. Since data in group collaborative systems are apt to be shared among multiple concurrent users and modified simutaneously by them, the web-based group collaborative systems must support synchronous collaboration in order to provide users with synchronized and consistent views of shared data. This Paper proposes an active web server which can facilitate synchronous collaboration in web-based group collaborative systems. To accomplish such a goal, the active web server manages dependency relationships between shared data and web browsers referencing them and actively propagates changing details of the shared data to all web browsers referencing them. And, this paper examines usefullness and effectiveness of the active web server to apply it to the ball-bearing design example of concurrent engineering design systems. The prototype system of the active web server is developed on a commercial Object-oriented Database Management System (ODBMS) called OBJECTSTORE using the C＋＋ programming language.

The web-based groupware systems hold many possibilities for system developers and users. Especially, web-based group collaborative systems are emerging as enterprise-wide information systems. Since data in group collaborative systems are apt to be shared among multiple concurrent users and modified simutaneously by them, the web-based group collaborative systems must support synchronous collaboration in order to provide users with synchronized and consistent views of shared data. However, current web technologies have limitations in supporting this, largely because the existing Hypertext Transfer Protocol(HTTP) is unidirectional and does not allow web servers to send messages to their web browsers without first receiving requests from them. This paper proposes an active web server that can overcome such limitations and facilitate synchronous collaboration in web-based group collaborative systems. To accomplish such goals, the active web server manages dependency relationships beween shared data and web browsers referencing them and actively propagates changing details of the shared data to all web browsers referencing them. And, this paper examines usefulness and effectiveness of the active web server to apply it to the ball-bearing design example of concurrent engineering design systems. The prototype system of the active web server is developed on a commercial Object-oriented Database Management System(0DBMS) called OBJECTSTERE using the C++ programming language.

Recently firms which have been using traditional VAN-EDI are adapting Web-EDI at very rapid pace. Based on the Internet, Web-EDI is easier to install, is cheaper and more accessible than VAN-EDI. Web-EDI establishes an electronic hierarchy as a type of Inter-Organization Information System. An electronic hierarchy connects two legally separate firms in an electronically mediated relationship. The primary reasons for establishing an electronic hierarchy is to improve the flow of materials and information between firms. This paper suggests two hypotheses that describe the possible impact of Web-EDI on firms in the Web-EDI network, and empirically tests them using data from a case study based on a discount store. The result is as follows. First, the more a firm utilizes information shared through Web-EDI, the higher the inventory turns. Second, a higher level of information sharing does not necessarily increase the inventory turns of Web-EDI adopters who are coerced to implement the electronic networks by the champion. These findings imply that the operational performance of Web-EDI adopters can be improved only when the firms intensively utilize the information shared through Web-EDI for their business processes.

Since most of CSCW(Computer-Supported Cooperative Work) systems have been developed for particular computing platforms, they are usable only within the specific organizations supporting those particular platforms. Recently, according to the rapid growth and continuing success of the World-Wide Web(WWW or Web) which offers a globally accessible platform-independent infrastructure, many CSCW systems has been constructed and is being developed on the basis of the Web. As one of such CSCW systems, in this paper, we describe the design and implementation of the CoSpace system. The CoSpace system provides shared workspaces, which enable members of a work group easily share information for collaborative work through their Web Browsers. The shared workspaces support information sharing and management between users, and also support event monitoring and synchronization between collaborative works.

공유 저작물 플랫폼은 공유 저작물 활성화를 위해 만들어 졌다. 이용 허락 절차를 간소화 하고 저작자 스스로 이용 범위를 표기해 배포함으로써 저작물 이용을 활성화 한다. 본 연구는 한국 공유저작물 플랫폼의 인터페이스 유형 및 특성을 분석하기 위해 다섯 개의 인터페이스 영역과 열다섯 개의 평가 항목을 선정하였으며, 국가 운영 플랫폼을 중심으로 분석하였다. 국가 운영 공공저작물 플랫폼인 공유마당, 공공누리와 민간 주도인 유로피아나의 웹 인터페이스 유형 및 특성을 분석함으로서 한국 공유저작물 웹 인터페이스의 상황을 비교 분석하고 개선 방안을 제언하고자 한다.

오늘날 우리는 인터넷에 연결된 PC뿐만 아니라, 이동형 기기인 휴대전화, 무선 인터넷을 이용하는 PDA, 노트북, 그리고 D-TV 등을 통해서도 웹서버에 접근하여 콘텐츠 형태의 정보를 얻고 있다. 본 연구에서는 이러한 환경을 지원하기 위하여 각각의 적응화된 컨텐츠를 저장하는 것을 기반으로 하며, 이를 다양한 기기를 지닌 사용자에게 활용하기 위해 페이지 정보를 지니는 메타 데이터를 적용하는 웹 캐싱 기법(SOP)를 제안한다.

본 연구의 목적은 웹기반 협력학습에서 상호작용의 패턴인 중심화가 공유정신모형, 만족도, 성취도에 미치는 영향을 분석하는 것이다. 총 68명의 학습자들이 7개의 팀에 무선할당 되어 4주간 웹기반 협력학습을 진행하였으며, 사회연결망 분석을 통해 중심화가 높은 그룹 3팀과 낮은 그룹 3팀이 선별되었다. 중심화가 높은 집단과 낮은 집단 간 공유정신모형, 만족도, 성취도의 차이를 검증한 결과, 두 집단 간 공유정신모형에는 차이가 없는 것으로 밝혀졌으나 만족도와 성취도의 경우 중심화가 높은 집단이 낮은 집단에 비해 더 높은 만족도와 학업성취도를 보였다. 이는 웹기반 협력학습에서 주도적인 역할을 수행하는 학습자가 있을 때 만족도와 성취도가 높아진다는 의미이며, 협력학습의 설계에 대한 시사점을 제공한다.

본 논문은 SNS와 Web에서 실시간으로 공유되는 정보를 추출하고, 추출한 데이터를 신속하게 분석하여 고객이 무엇을 원하는 지를 분석해서 온라인 마케팅 전략을 효율적으로 만드는 SNS와 Web기반 BDAS(Big data Data Analysis Scheme)을 제안한다. 제안하는 BDAS는 첫째, SNS와 Web에서 공유되는 데이터를 수집하고, 둘째, 수집된 데이터의 의미를 긍정과 부정으로 분석하여 그 결과를 시각화하여 제공한다. 그 결과, BDAS는 공유되는 SNS와 Web 데이터에 대한 의미를 판단하는데 있어서 평균 90%의 정확성을 보장한다. 따라서 본 논문에서 제안하는 BDAS를 이용하여 소비자의 성향을 정확하게 판단할 수 있으므로 온라인 마케팅에 보다 효율적으로 활용할 수 있을 것이다.

One of the important performance metrics of the World Wide Web is how fast and precise a request from users will be serviced successfully. Shared Web Caching (SWC) is one of the techniques to improve the performance of the network system. In Shared Web Caching Systems, the key issue is on deciding when and where an item is cached, and also how to transfer the correct and reliable information to the users quickly. Such SWC distributes the items to the proxies which have sufficient capacity such as the processing time and the cache sizes. In this study, the Hot Spot Prediction Algorithm (HSPA) has been suggested to improve the consistent hashing algorithm in the point of the load balancing, hit rate with a shorter response time. This method predicts the popular hot spots using a prediction model. The hot spots have been patched to the proper proxies according to the load-balancing algorithm. Also a simulator is developed to utilize the suggested algorithm using PERL language. The computer simulation result proves the performance of the suggested algorithm. The suggested algorithm is tested using the consistent hashing in the point of the load balancing and the hit rate.
