The Internet has become widely used in many countries. In particular, a new emerging technology, the WWW (World Wide Web), which has become a major application of the Internet, has been rapidly developed. As a result, there are hundreds of millions of URLs (Uniform Resource Locators) on the WWW, and the total number of URLs is still explosively increasing. To get information from the WWW, we generally use Internet search engines. However, we cannot always get the actual information we want. Accordingly, we have solved this problem by constructing a prototype system based on agents by programming language Java for constructing a more effective search engine. This so-called “intelligent agent system on WWW” deletes redundant HTML (Hyper Text Markup Language) files and exchanges information about the existence of URLs. And we found that our prototype system is more powerful and effective than conventional search engines.

This paper supposes the SNMP network management system based upon Mobile Agent using the Naming and Directory Service, which is JNDI(Java Naming Directory Interface) technology. The Mobile Agent network system is expected to provide a solution for the conventional centralized network system. So, We have designed and implemented the network management system based upon Mobile Agent using JNDI

Information-oriented society will be developed more rapidly with internet. In this trend, many foreign countries support research on mathematics education using information technology that is also needed in this country. This article shows a mathematical puzzle database related to mathematics education using Java script to be activated on internet service.

U-Eco City is promoted nation-wide by development of recent IT technology, method of effective countermeasure disasters, which real-time wire/wireless communication network, and 3D-Web GIS shall be connected that massive database, intelligent service be perceived. U&V-City is the four-dimensional future city that actualizes an intelligent daily ubiquitous computing service by embodying 3D-Virtual City, the reproduction of real world U-City while using Digital map, satellite image, VRML(Virtual Reality Modeling Language), which are presentation tool to describe city components and by efficiently catch and cope about nature and human disasters while employing EAI(External Authoring Interface) that provides HTML&JAVA, and interface for efficient removal/process of massive information/service and also by employing GPS/LBS/Navigation in support of the world-wide orientation concept, and RTLS(Real Time Location System).

A medical image management system was implemented using WWW(world wide web) technology. The Httpd server was designed using PC with Linux operating system. The client used Netscape as its network browser. The image processing module of the client part was programmed in Java. The database was constructed with Bicom3 format images and programmed using Perl. The present technique can be used to standardize the network and user environment of PACS and teleradiology.

오늘날 많은 웹 페이지들이 제한적인 정보의 제공에서 벗어나 ActiveX Control이나 Java Applet과 같은 응용프로그램을 사용자 컴퓨터에 다운로드 하게 하여 다양한 서비스를 제공하고 있다. 이러한 과정에서 인터넷을 통해 다운로드 되는 소프트웨어에 대한 무결성과 배포자에 대한 신원 확인을 해주는 코드 서명 기술이 필요하게 되었다. 본 논문에서는 Microsoft사의 Authenticode와 Netscape의 Object Signing기술에 대하여 분석하고 이러한 코드 서명 기술을 국내 공개키 기반구조(PKI)에 적용하기 위한 인증서 프로파일을 제안한다.

In this paper, we designed a new type of X-internet framework by using Flash component and server service API and analyzed its performance. Proposed X-internet framework uses Flash MX Professional 2004, Java, and software which opened middleware and database. Since proposed framework use the server service API that we developed in this paper and Flash player, this framework does not need server module. Proposed framework enables to obtain design with dynamic user interface compare to Web application and enables to reduce development time. In analytical results, it has been shown that proposed x-internet framework have efficient characteristics such as network traffic, low development cost and dynamic user interface implementation. Since proposed X-internet framework can operate in environment of current developer friendly, it is useful for development of various new application programs and we confirm it through Flash web mail implementation by using proposed x-internet framework.

다수에 의한 다수에 대한 P2P 전자경매 시스템에 대한 모델과 Java 의 Jini 기술을 기반으로 하는 구축방안에 대하여 기술한다. Jini Service 형태로 네트웍에 공개되는 모든 전자경매 진행관련 정보에 대한 검색과 입찰 처리과정을 자동화 할 수 있을 뿐만 아니라, 네트웍 문제 발생에 대한 자동복원, 참가 이후 신규 공개되는 정보에 대한 비동기 자동 확인, 그리고 ACID 개념을 보장하는 트랜잭션 관리 등이 가능하다. 다양한 MIME 타입을 지원하는 컨텐츠와 EJB 를 활용할 경우 유선 및 무선 정보화장치를 통하여 모델에 참여할 수 있으며, 수동 접속된 특정 서버의 제공 정보 및 절차에 제한 받지 않는다.
