There are many kinds of research on web graph, most of them are focus on the hyperlinked structure of the web graph. Well known results on the web graph are rich-get-richer phenomenon, small-world phenomenon, scale-free network, etc. In this paper, we define 3 new directed web graph, so called the Web Usage Pattern Graph (WUPG), that nodes represent web sites arid arcs between nodes represent a movement between two sites by users' browsing behavior. The data to constructing the WUPG, approximately 56,000 records, are gathered from some users' PCs. The results analysing the data summarized as follows : (i) extremely rich-get-richer phenomenon (ii) average path length between sites is significantly less than the previous one (iii) less external hyperlinks, more internal hyperlinks.

최근 GIS의 보급이 증가하고 공간 데이터 사용자의 요구수준이 높아짐에 따라 웹기반 GIS에서는 단순히 공간 데이터를 지도화하는 것뿐만 아니라 다양한 공간분석과 프로세싱을 통해 공간 정보 및 지식을 효율적으로 제공할 필요성이 제기되고 있다. 또한 공개 GIS 소프트웨어의 발전은 이러한 웹 GIS의 요구를 실현하기 위한 기술적 토대가 되어가고 있다. 본 연구는 공개 GIS 소프트웨어인 GRASS를 이용하여 래스터 데이터의 지도대수 연산을 수행하는 웹 분석 시스템을 구축하는 것을 목적으로 한다. 웹에서의 데이터 분석 방법은 래스터 데이터 처리 시 널리 사용되는 지도대수로 하였으며, 중첩분석에 필요한 가중치는 AHP로 계산하였다. GRASS 기반의 웹 분석 시스템을 구축한 후, 강수량, 표고, 경사각, 경사방향, 토양의 래스터 레이어를 이용하여 산사태 위험도 분석을 시범적으로 구현하였다. 웹과 GRASS의 연동을 통해 지도대수뿐만 아니라 다른 공간분석도 가능할 것으로 기대된다.

To propose the construction of architectural interior design and communication using graphic, web3D, it was studied the kind and character of various representation methods that can be embodied in an architectural interior design on the web, and looks into whether these ways can be adapted to an architectural interior design process. Especially, the use of the current techniques on graphic and CAD data give the most suitable effect by using the integrated data such as vector animation, an interaction of object VR(Virtual Reality), a high quality of panorama VR, and data treatment and its interaction of drawing of cad data. As a result, the single data format shows not only one image representation but also a stream of continuous operation through a change into another format. But this desired study expects that another next studies will go on interaction and integration of digital format with increase of transmission speed expected in the future, and a digital model and its practical methods.

Recently as users' requests for geographic information systems are being more various, several new functions are being added to existing geographic information systems. One of them is linkage of spatial geographic data and video / image data to offer more realistic information of geographic objects to users. Geographic information systems implementing this function are called video geographic information system. In this paper, we design and implement a video geographic information system for providing map data, video data and link information of them to web applications. We 1) design system architecture of a video geographic information system, 2) analyze some processes to construct link information of map data and video data, 3) design database schema to store map data, video data, and link information, and 4) design some XML/GML schema used to query and retrieve these data for web applications.

본 연구는 국내 지하수 자료의 효율적 이용 관리를 위한 수량수질 정보의 통합관리 시스템인 "국가지하수정보지도" 구축을 위한 업무분석과 세부 설계를 실시하고 천안 및 대구지역에 시범 적용함으로써 그 효용성을 검토하고자 하였다. 본 시스템에는 지하수와 관련된 관측, 조사, 지구화학(이온분석 결과), 시설, 수질검사 및 도면 자료 등을 데이터베이스로 포함하고 있으며, 전국의 약 130만개 관정에 대한 상세정보를 기본 데이터로 활용한다. Web 환경의 GIS 시스템인 "국가지하수 정보지도"에서는 자료의 검색뿐 아니라 시계열분석, 공간분석, 지층단면작성 등의 분석 기능이 포함되어 있어 지방자치단체 공무원뿐 아니라 현장 기술자에게도 유용하게 활용될 수 있다. 앞으로 본 시스템을 지하수에 대한 표준 모델로 발전시키고 단계적으로 확장해 나감으로써 전국의 지하수 관리를 보다 체계적으로 수행 가능하게 될 것이다.

The purpose of this study is to develop Web database for healthy city that contains healthy city indicators for making city health plans, setting project priorities, monitoring projects, and evaluating healthy city projects, effectively. Using Delphi survey method for identifying indicator domains and indicators, we extracted nine domains with thirty-four healthy city indicators. Based on the appraisals of DB users about the contents of DB, a web database for healthy city Wonju was constructed. We developed a web database system for the purposes of sharing high quality health related data for managing and evaluating healthy city projects. The web database currently provides variety data in the web address, http://healthycity.wonju.go.kr/index.html. The web DB comprised with major healthy city indicators that are the most important indicators, healthy city indicator data that have a variety data set for encompassing all domain areas such as city infrastructure, health medicine, economies, and all other related areas and qualitative data that contains policy reports, research results, healthy city information and all other tips. A database of healthy city is very essential and important because it makes healthy city projects alive by managing and sharing healthy city related data effectively. But we need to fill out some blank cells in DB because there are currently unavailable data for some indicators. In conclusion, we expect the web DB contributes information sharing of healthy city project teams and improving healthy city project quality at Wonju city in Korea.

Recently as the power system has been becoming massive and complicated, most of the faults bring on severe proliferation effects. Because of the complexity of the power system it is not easy to analyze faults-the calculation of current flows under fault conditions. Therefore many researches have been performed in this area. As a result of those efforts, the protective equipments for a power system have been designed to operate properly and without damage when the highest possible fault current is flowing in the power system. Most of the fault data can be also acquired from intelligent protection equipments. The fault data saved in them don't always include the fault type information. n you don't have knowledge about the fault analysis, it becomes useless. So this paper presents 3 topics to increase a reusability of them as followings. First, describes a fault data using the XML(extensible Markup Language). It would be a well-formed and valid document complied with suggested XML DTD(Document Type Definition). In this paper I suggest a standard DTD to describe the power system fault. If the XML document describes any power system faults is validated against suggested DTD, it is possible to be used in any applications. Second, sends them through the web using the XML web service. Last, presents the rapid and accurate algorithm for a fault type determination of the fault data received from the web. In the ultimate the client to request the server to analyze a fault data is provided the correct information what kind of fault is occurred.

The Semantic Web is an evolving extension of the WWW in which the semantics of information and services on the web is defined, making it possible for the web to understand and satisfy the requests of people and machines to use the web content. The sementic web relied on the ontologies that structure underling data for the purpose of comprehensive and transportable machine understanding. The Semantic Web relies on the ontologies that structure underlying data for the purpose of comprehensive and transportable machine understanding. And recommendation systems have been developed as a solution to the abundance of choice people face in many situations. This paper shows that the new recommendation method is suitable for effective recommendation on the semantic web. We present a new procedure for improving the effective recommendation by using the levelized context ontology. Our experimental results also confirm that our method has good recommendation time. Our proposed method can be generalized to fit other application domains.

Visitors to a Web site leave access logs documenting their activity in the site. These access logs provide a valuable source of information about the visitors' access patterns in the Web site. In addition to the pages that the user visited, it is generally possible to discover the geographical locations of the visitors. Web servers also records other information such as the entry into the site, the URL, the used operating system and the browser, etc. There are several Web mining techniques to extract useful information from such information and visualization of a Web log is one of those techniques. This paper presents a technique as well as a case a study of visualizing a Web log.
