The project of advanced urban transit system (AUTS)development is developing the advanced vehicle and the core technologies for the cost down by system change, the transport safety and the environmental friendliness and the improvement of passenger service. The product data management(PDM) system is installed for management of each project. Various data and informations producted from each project are made for database. We developed the product data management system for advanced urban transit system. In past, it was AUTS-PDM of C/S version. Now, we develop AUTS-PDM of Web version.

본 논문에서는 UML 편집기에서 생성된 mdl 형태의 파일을 웹 상에서 공유하기 적합한 XML 형태로 변환하여 관계형 데이터베이스에 저장하고, 각종 설계 정보들을 웹 환경에서 팀들간 공동 작업을 위해서 웹 브라우저를 통해 참조하고, 파악되도록 하기 위한 방안을 기술한다. 또한 웹 기반의 소프트웨어 공동 개발 환경에서 얻어진 많은 소스코드와 실행파일 그리고 오브젝트파일들을 프로젝트 팀들간에 공유할 수 있는 환경을 지원하는 웹 기반의 시소러스를 이용한 검색 시스템을 지원하며, 이들 설계정보들 간의 관계를 웹 상에서 유기적으로 항해할 수 있는 항해 도구 시스템에 관한 연구이다.

National Agricultural Pesticide Risk Analysis (NAPRA) World Wide Web (WWW) 시스템 (http://danpatch.ecn.purdue.edu/${\sim}napra$)은 다양한 영농방법에 따른 농약과 영양물질의 지표수/지하수 유실량을 웹에서 모의하고자 개발되었다. 단일 토양에 대해서 모의할 수 있는 Single Field 버전의 많은 기능이 개선되었고, 행정구역/수계 경계에 대해서 모의할 수 있는 County/Watershed 버전을 확장시켜, Web Geographic Information Systems (GIS) 버전의 NAPRA 시스템을 개발하였다. Web GIS 툴을 이용하면, 모의하고자 하는 지역을 마우스로 디지타이징 한 후, 그 지역에 대해서 영농방법에 따른 영향을 모의할 수 있다. 모의결과를 웹브라우저를 통해서 지도로 보여줄 뿐만 아니라, 그 결과를 데스크탑용 GIS에서 사용할 수 있는 포맷으로 제공한다. 모델을 운영하기 위하여 방대한 양의 입력자료가 필요하고, 일반 사용자가 준비하기 힘든, 데이터들이 있는데, NAPRA WWW 시스템은 이러한 입력자료를 서버측 GIS 데이터 베이스, NAPRA 데이터 베이스, 강우 및 온도 모델 예측치 에서 추출하여 모델을 운영한다. 또한, 모의결과를 방대한 양의 텍스트 파일이 아닌, 차트나, 테이블, 또는 지도형태로 보여주기 때문에, 농부와 같이 전문지식이 없는 사람이 이 시스템을 이용하여 여러 가지 영농 방법 중에서 환경 친화적이면서 경제성을 유지 할 수 있는 최적관리기법을 찾아낼 수 있다.

It is well known that the web design is composed of several factors which are interacting with each other. However, the current approach to web design had been focused on modifying specific factors without considering its impact on other factors. In this sense, we propose more holistic approach to the web design by using fuzzy cognitive map. For this purpose, we form an illustrative fuzzy cognitive map for the web design which is based on the literature, and analyzed and impact of change in a specific factor on other factors. Especially, to improve the output analyzability, we suggested an advanced version of fuzzy cognitive map called stratified fuzzy cognitive map. After simulating the fuzzy cognitive map for web design, we could conclude that our approach is robust and effective compared to the traditional web design approach.

The popularity of web services within the IT industry continues to grow as the next generation web technologies. Web services are self·contained, self-describing, modular applications that can be published, located, and invoked across the Web. Web services will be core technology for e-business in the Web. IPv6 is sometimes also called the Next Generation Internet Protocol and is a new version of IP which is designed to be an evolutionary step from IPv4. In this paper, we define problems for adapting web services to IPv6 Environment. This paper survey and explain consideration issues that include standards, components, coexistence of IPv6 and IPv4, etc.

Recently Web Services choreography working group of W3C has published the working draft on WSCDL (Web Services Choreography Description Language) version 1.0 which defines reusable common rules to govern the ordering of exchanged messages between Web Services participants. This paper considers a computing environment where mobile clients are interacting with Web Services providers based on a WSCDL specification. In order to effectively cope with the user and device mobility of such an environment, in this paper we present an ongoing work to develop a framework through which a mobile client can specify its preference on how conversation should take place. The proposed framework provides a flexible means for mobile clients to minimize the number of message exchanges while allowing them to adhere to the required choreography.

The purpose of this study was to develop game style courseware in oral health instruction for elementary school children. The manufacturing equipment and languages which were used to develop the courseware were： Photoshop version 7.0, Illustrator version 10.0, HTML, Dream Weaver MX, Editplus, CSS and Java - script. The data base was built up by using PHP and mySQL over Internet Explorer version 4.0. The contents of courseware for oral health education were based on the list of oral health affaires of the Department of Health and Welfare, 2002. The story of the game ‘Saving Hayani locked down in a castle of a cavity man’ was developed for the learners to learn oral health by inducing learning motivation. A character named ‘Chan i’ was introduced to the learners to be more friendly with the program while they were learning. As the game was made of three step education levels, the learner most pass the prepared test given at each step to advance to a higher level. A database connected to web was constructed to store the scores the learners earned at each step. In conclusion, the courseware will help the elementary school children learn oral health care efficiently through the internet regardless of time and space.

We have designed embedded web sewer system and ported Linux operating system version 2.4.5 at our system. And then We implemented to control and monitor widely separated hardware and implemented to monitor widely separated image using CMOS image sensor HV7131B. Web server is the Boa web server with General Public License. We designed for this system using of Intel's SA1110 ARM core base processor and connecting input and output device at GPIO port of SA1110. Device driver of General purpose I/O for Embedded Linux OS is designed. And then the application program controlling driver is implemented to use of common gate interface C language. User is available to control and monitor at client PC. This method have benefit to reduce the Expenditure of hardware design and development time against PC base system and have various and capacious application against firmware base system.

This paper introduces a new web based method to remotely upgrade firmwares of Cable Modems (CM) which are integral part in providing high-speed Internet access through Hybrid Fiber Coaxial (HFC) networks. Also, it discusses various practical problems arising in the upgrading process. Traditional upgrade has been performed by modifying the CM configuration fie. This paper shows a new web based CM firmware upgrade method using SNMP and MIB which greatly reduces upgrading time, cost and man-hour than traditional firmware upgrade methods. This method has been shown to be very efficient and practical. This method will make significant impact especially because tens of million cable modems are currently waiting to be upgraded soon to the next version from the current version.

SNMP is a standard protocol for management of networking devices. Nowadays, most computer systems have capability to act as SNMP agents. In this paper, we describe our system monitoring software based on SNMP. It consists of a monitoring server, SNMP agents, and client programs. The monitoring server collects status information from the SNMP agents running on the monitoring target graphical display. We developed two version of clients, Java based standalone program and Web based program. Since most known SNMP packages are too big and heavy, we developed an efficient version of SNMP library for out system monitoring.
