A fundamental issue to consider when searching Web information is the quality of information itself and of service. If a Quality Information System (QIS) of Digital Library is sought, new measurement criteria and evaluation index for Web information service are required. Reliance on the existing evaluation criteria is not acceptable if data retrieved are not information and the service is only noise to end-user. Applying existing evaluation criteria of online database to Environmental & Energy Engineering Web DB revealed the limitations and provided a practical and case-based information for improvement. No attempt was made to survey comprehensively all of the evaluation methods that could possibly be relevant. Instead, this discussion concentrates on the information service evaluation index being developed in the KDPC Project. The research found that domestic Web-DB service are still woefully insufficient to conduct comprehensive investigations on environmental topics. More qualified and specialized R&D Web information service and the development of new evaluation criteria based on this investigation(research I.) will be discussed in follow-up research II.

In the era of Web 2.0, users create a number of their own Web contents. So, multimedia search becomes much more important than ever. A tag is a simple keyword which describes the Web contents including URL, pictures, and videos. Tags perform a role of descriptors of Web contents and Web metadata properly. If the number of tagged Web data increases, users are more likely to find the desired search result because the system includes the Web contents which have richer Web metadata. However, the number of users who use tags as Web metadata is relatively small. Because of the cumbersome process of adding tags, or users do not know what to add for the better accessibility from the public. Given situation, tag recommendation, which helps the process of adding tags, has been studied to solve these problems. When a user adds some Web contents, the tag recommendation system recommends relevant tags for the Web contents to the use, and the user selects recommended tags. We analyze and categorize various tag recommendation algorithms in tagging system.

Deep web collection means entering a query in a search form and collecting response results. It is estimated that the information possessed by the deep web has about 450 to 550 times more information than the statically constructed surface web. The static method does not show the changed information until the web page is refreshed, but the dynamic web page method updates the necessary information in real time and provides real-time information without reloading the web page, but crawler has difficulty accessing the updated information. Therefore, there is a need for a way to automatically collect information on these deep webs using a crawler. Therefore, this paper proposes a method of utilizing scripts as general links, and for this purpose, an algorithm that can utilize client scripts like regular URLs is proposed and experimented. The proposed algorithm focused on collecting web information by menu navigation and script execution instead of the usual method of entering data into search forms.

In this paper, web based monitoring systems are implemented for multi-axis force control systems of an intelligent robot. Linux operating systems are ported to an embedded system which Include a Xscale processor to implement a web based monitoring system. A device driver is developed to receive data from multi-axis force sensors of intelligent robots. To control this device driver, a socket program for Labview is also developed.

In this paper, we implemented a web-based communication system using Motion JPEG and RTP. MJPEG compression method is used for compression of the image in order to film and transmit the moving image information in the real time, and the RTP(Real-Time Transport Protocol) which differs from the existing TCP and UDP is used for the data transmission.

지역의 DATA를 수집하여 이를 DB로 구축하고, 이를 유통시스템화하여 WEB 환경에서 활용하고자 하는 지역정보화 사업에 대하여 객관적인 입장에서 새롭게 분석하고 연구하여야 할 필요서이 제기되고 있다. 이 연구에서는 그 동안 진행되어온 전라남도의 지역정보화 사업과 인천 광역시에서 추진하였던 WEB 시스템하에서 HTML을 활용한 지역정보화사업을 비교하고 검토하는 과정에서 지역 정보화 사업의 방향을 재설정하고, 이에 따른 활성화 방안을 도출해 보고자한다.

This paper explores ways to develop efficient methods to construct the web-based interior design database based on hypermedia technology. First the role of hypermedia in design was investigated. We propose the structure of knowledge representation for interior design works. Also, we discuss how a design case can be retrieved from the design database. This paper also identified further research issues such as design case retrieval from numerous design cases and components of the virtual design studio.

This paper presents a design and implementation of cyber-school system using object modeling technique and web groupware. The system design method based on object modeling techniques reduce cyber-school construction effort and cost with reusing of modules. The system is a kind of web group application based on WWW that allow members who located on remote computer to do cooperative learning and to communicate with other students and teachers independent of time and location. In this system we use Linux operating system for efficient development on real education field. and we can reduce cyber-school development effort arid cost With this system.

This paper presents a solid modeling system that enables real time co-operative modeling and discussion on m between geographically separated designers. The modeling system is implemented using CORBA architecture and integrated in WWW with Java technology. The server objects use a commercial solid modeling kernel to provide modeling features and access database including product model data. The client is implemented using Java2 platform so that enables end-users access the system with web-browsers.

대기오염의 현황을 인지하고 현실적인 관리를 하기 위해서는 대기오염 물질의 배출량을 산정하는 것이 매우 중요하다. 이를 통해 대기오염 모델의 입력자료, 주요 배출원의 파악 및 기여정도를 평가할 수 있으며, 대기관리정책의 수립 및 평가의 기초자료로 사용될 수 있다. 미국 Aerometric Information Retrieval System(AIRS)과 유럽 CORINAIR(EU 내에서 data 호환을 위한 규약)의 경우에는 대기오염물질 배출량 정보를 WWW(World Wide Web：이하 WWW) 상에서 공개함으로써 배출량 연구의 공유와 표준화가 이루어져 있다.
