다양한 응용분야에서 사용되고 있는 웹은 최근 전자상거래 둥에서의 이용에 대한 기대가 한층 고조되고 있다. 그러나 이러한 웹은 전자상거래 행위에서 특히 중요한 부인봉쇄 서비스가 제공되고 있지 않으며 64비트 이하의 비도로 기밀성 서비스를 제공하고 있다. 이 논문에서는 WWW의 보안 요구사항 및 이를 위한 WWW 프로토콜로 IETF(Internet Engieering Task force)에서 제안한 S-HTTP(Secure HTTP, Secure HyperText Transfer Protocol)를 기반으로 하는 안전한 WWW시스템 개발, Apache-Shttp를 위한 기능 설계, 개발 환경 및 개발된 시스템의 시연을 기술한다.

In this paper, we develope a intelligent monitoring system of Coastal Ocean Environment based on WWW(World Wide Web) and PCS(Personal Communication System). This system have capability of real time processing of enviromental variable from various sensors. The system is composed of three part. The first part is mathematical modeling of real ocean. The second is construction server for real time web page. And the third is developing the measurement system which has wireless(PCS) interface to server.

WWW 의 발전과 함께 발생한 역기능으로 사용자의 계정 도용을 통해 사용자의 프라이대시를 침해하거나 도용한 계정의 권한을 남용하는 등의 문제가 발생하고 있다. HTTP는 기초적인 사용자 인증 기법을 지원하고 있으나 취약성이 존재하고. 이를 위해 소개된 메시지 축약을 응용한 새로운 인증기법 역시 구현의 불편함이나 브라우저의 지원 부족으로 거의 사용되지 않고 있다. 이러한 인증 과정을 단순화하고 대부분 웹 브라우저가 지원하는 애플릿을 통해 구현함으로써 수정으로 현재 서비스 중인 사이트에 적용할 수 있다. 이러한 안전한 인증 과정을 통해 사용자 도용 문제를 줄일 수 있다.

Realty Trade Information Hanagement System(RTIMS) is intended to provide the services relat¬ed to realty business activity such as registration, search, negotiation, and information analysis. Introduction of the geographic information processing concept into the system has a great effect on the overall service processes of the realty business. This system is designed and implemented for remote users to easily get the informations about the target realty and to achieve a proper negotiation, by offering the various kinds of geographic informations including map, moving picture, photo, and so on. Futher, users can access RTIMS through WWW(World Wide Web) without additional client emulator.

An analytical of throughput and delay on reverse link in a cellular slotted CDMA system with integrated voice and World Wide Web (WWW) traffic is presented in this paper. Our results show that the Gaussian approximation it was found that the voice traffic can have a significant impact on the WWW traffic. It was also found that the different mobiles velocity and number of resolvable paths is impact each other the system performance.

Korea Aerospace Research Institute(KARl) has been receiving Terra and Aqua MODIS data at ground station of Daejeon since July 2002. MODIS data can cover whole East Asia including the Korean Peninsula, Japan and The East China each almost scene and is monitoring ocean, atmosphere and land. By this time, over two thousand scenes have been archived including Terra and Aqua in the storage system and they occupied about over 10TB of disk space. In this study, Web-Downloading system of MODIS data developed on WWW is including following main functions: spectral subset (250m, 500m, 1000m chnnels) Level 1B data of HDF format, result display, ftp download and statistic viewer etc. Users using this system can directly download MODIS data on WWW with a few input parameters. This system is available via the Internet URL after October 2005 on the following, 'http://webmodis.kari.re.kr/'

In recent years, Internet/Intranet represents the next generation of computing environment. Therefore, it is necessary to integrate WWW((World Wide Web) over internet/intranet and DBMS(Database Management System) in proportion to the increase of various users' request and an amount of data variety. Also, also full variety of service over WWW need to accomplish rapidly modification of bug and make a betterment of system according to a feature of rapid change of information and an importance of interaction with users. The typical CGI method commonly used to connect with database has a disadvantage in time and resources in system due to frequent connection with database. Therefore, this paper provides the conceptual structure and implementation of information management system over WWW with applying a recent information technology called ASP(Active Server Pages) that controls and arranges client logic dynamically in server-side and introducing a concept of working group and folder to database design.

The purpose of this study is to investigate how and which meta tags are used, which meta tags are used frequently, and what relationships there are between retrieval of WWW documents and meta tags. For the study, 1,000 WWW documents were selected and examined from OCLC NetFirst. The total of 92 meta tags was discovered and "description" and "keywords"meta tags were analyzed intensively. In addition, analysis of WWW documents showed that there are no significant relationships in meta tag usages between documents retrieved at the beginning and documents retrieved at the end. Comparative study between general internet search engines and commercial DBs such as NetFirst is suggested as a further study.

n this paper, we propose a WBI(Web Based Instruction) for individualized learning using push and pull technologies with WWW(World Wide Web). As well as push End pull technologies, the proposing system is implemented with JSP(Java Server Page) and JDBC(Java Database Connectivity) of java technologies based on the client/server envirionments for the purpose of providing practical lectures to students.

As the lifecycle of a product becomes shorter, the communication between a contractor and a supplier in product information has got more importance. The CITIS(Contractor Integrated Technical Information Service) is required to provide authorized users with access to both data and applications they need to complete a task for contract. With the growth of WWW, there has been much study for the use of WWW for the implementation of CALS. The WWW has been proved as an efficient tool for CALS implementation due to its of publicity, openness, and free accessibility. In this study, we suggest using WWW tools, here, an intranet tool, as a basis for the implementation of CITIS
