지금까지의 국내외 연구들에서 다루어 왔던 TAM 연구들의 대부분은 사용 용이성과 유용성이 정보기술의 사용에 어떤 관련성이 있는가에 연구의 초점을 맞추어 왔다. 하지만, TAM의 구성요소중 하나인 외부변수에 대한 구체적인 정의가 동반되지 못했다 이에 본 논문에서는 TAM의 외부변수들을 선행된 연구들에서 찾아 정리하고, 개인적 변수와 조직적 변수로 크게 분류하여 이들 변수들이 사용 용이성과 유용성에 어떠한 영향을 주는 지를 연구함으로써, 사회나 조직 구성원들이 정보기술을 습득하고 수용하는 일련의 과정을 연구하는 것을 그 목적으로 하고 있다.

A categorical data analysis system in the World Wide Web is proposed with an easy- to-use environment . This system is composed of four components. First, this system presents several graphical displays for Exploratory Data Analysis for categorical data. Second, it provides some measures of association Including dynamic graphics for mosaic plots of Hartigan and Kleiner (1981) and Friendly (1994). Dynamic graphics for mosaic plots give some useful informations. Third, this system can analyze categorical data with loglinear models. So we can select the best fitted loglinear model interactively.

정보기술(Information Technology ; IT)의 발전을 대표하는 상징 중에 하나는 것은 각 가정에 설치된 개인용 컴퓨터(Personal Computer)를 들 수 있다. 즉, PC의 보급이 광범위해지면서 PC가 생산, 보유한 정보를 서로 공유하고 교환할 필요성을 느끼게 되어 특정 개인의 PC에만 국한되지 않고 networked PC가 필요하게 되었고, PC간의 데이터통신을 위한 다양한 기술들이 개발되기 시작하였다. 그 첫 번째 시도가 지리적으로 가까이 있는 컴퓨터간의 통신네트워크를 구성하려는 시도였는데, 이것이 근거리 통신망(LAN)과 1990년대 중반에 탄생한 웹(WWW; world wide web)의 출현이다.

World Wide Web(WWW) 데이터가 폭발적으로 증가하고 있는 시점에서, WWW의 데이터로부터 유용한 정보를 찾아내고 분석하는 일이 필요해졌다. 또한 WWW의 데이터만으로는 얻을 수 없는 기업의 의사결정을 위한 정보를 얻기 위해, 웹 페이지 접근 기록에서 얻어진 웹 로그기록들과 기업의 판매 트랜잭션 데이터베이스, 광고 데이터베이스 그리고 고객 정보를 통합하여 데이터 웨어하우스를 구축한다. 이러한 과정은 기업활동의 결과로 축적된 데이터 자원과 WWW의 데이터를 통합하여 체계적인 정보기반을 구축하고, 이러한 자원을 전략적으로 재활용하는 것이 목적이다. 본 논문에서는 WWW의 데이터와 기업의 데이터베이스를 통합하여 웨어하우스를 설계하고 여기에 데이터마이닝, OLAP을 적용하여 CRM에 활용하는 방안을 제안하고자 한다.

XML은 1996년 W3C(World Wide Web Consortium)에서 제안한 것으로서, 웹 상에서 구조화된 문서를 전송 가능하도록 설계된 표준이며, 기존 HTML의 한계를 극복하고 SGML의 복잡함을 해결하는 방안으로 등장하게 되었다. 최근 다양한 형태의 문서들을 XML로 전자 문서화하여 관리하려는 시도가 전자상거래, 전자도서관, 전자 정부, 기술 문서 관리 등의 다양한 응용분야에서 급격히 증대되고 있다. 본 논문에서는 이러한 인터넷/인트라넷 환경에서 급격히 늘어나고 있는 대용량의 XML 문서를 구조정보와 함께 저장 관리하고. 고성능 구조검색을 지원하는 시스템을 설계하고 구현한다.

Nowdays the need of modeling a real world using computers leads to increase the importance of GIS. Moreover, the wide spread of the Internet service has brought about Web GIS Development. Especially, the tuning of Web GIS system has a crucial role in improving the performance of high resolution image Web GIS system. Thus, this study provides a variety of ways to improve the performance of high resolution image Web GIS system. We have tuned IBM AIX operation system, Oracle, ArcSDE in the database level and Tomcat, ArcIMS in the application level. What is more, we propose ways of coding which can have a positive impact on performance. As a result, the proposed methods guarantee high resolution image Web GIS system to improve performance.

In this paper, the aims are to develop convenient and safe system-solutions, looking for missing-child, which is one of the increasing social problems, on the basis of World Wide Web. Finger-print cognition has been researching from long time before, as well as Bio-cognition technology, which is adapted for private-cognition in the field of human-cognition. By the fingerprint cognition, which discern finger print, which is generally used in Bio-cognition and is characterized each by using image-processing, missing-child protection system on the basis of Word Wide Web is designed and implemented in this paper. Additionally, indicates plans for revitalization method of this system.

This study is aimed at the development of comprehensive environmental management system, which can be operated on the basis of world wide web, as a topic of G7 project. Even though there should be lots of works remaining to achieve this goal, preliminary products can be summarized as follows : 1) integrated environmental information management system, 2) web based control engine, 3) surface water environment management system, 4) subsurface water environment management system, 5) sewer and waterworks management system. The core methodology of the engine is the generalized multidimensional finite element matrices to depict the terms in the analysis of various partial differential equations. Spatial information management system (ArcView) and Visual Basic were extensively employed to construct GUI oriented web based engine. The developed systems were composed of very intense computer codes due to the necessity of combinatory management of environmental problems. The web based engine could be served as a decision tool for the integrated management of environmental projects in Korea.

Recently, many web-enabled personal devices are becoming available for connecting to the internet, and there are many use]-s who access the internet from hand-held devices such as PDAs, cell phones. Most pages on the world wide web are designed for displaying on desktop computers with color monitor having at least 640$\times$480 resolution. But these devices do not have the same rendering capabilities as desktop computer, so the same web content needs to be rendered differently on hand-held devices. Therefore, there have been a variety of web transcoding techniques proposed to solve the problem between the web contents and hand-held devices. In this paper, we propose a web transcoding system(WebPrism) for real-time information providing using the semi-automatic transcoding method. The semi-automatic web transcoding method is a good solution when if mobile users access the limited number of web pages which layout is not changed frequently, also WebPrism is implemented as a desktop PC and experimental result shows that the proposed system generates the best looking document for a given display size of PDA.

Recent days, the global warming problem due to excessive use of fossil fuels has been the world wide issue so that Korea government and developed countries make an alternative plan for eco-friendly and transportations by utilizing bicycles for health promotion. Existing Public Bicycle Rental Service Systems provide simple service such as bicycle rental management and tracking the location. However there is no user-side service for the information of the measure of carbon reduction, or use of bicycles. The proposed system in this paper provides users' health information, environmental information, personal information, counseling services and the measures of carbon reduction. The new system has been developed to carry out reducing carbon and growing green in terms of using bicycles by adopting Web 2.0 technology.
