The purpose of this study is to identify important web pages in a particular area The basic premise is that citation analysis can show a similar relationship among different web pages. Web pages about‘weather’were found using a search engine Each web page was examined by hyperlink from other web pases and/or to other web pages. After this process, seven web pases are linked by many web pages. Seven web pages were analyzed by co-citation analysis. The result shows that selected web pages are linked by characteristics of information provided.

In this study, sub domain of flow was investigated on literature survey, and suggested of the measuring method of web-site flow and its simulation analysis. Constructing of measuring method of flow, and using this method what-if analysis was simulated when several condition changed. Using causal map approach to extract knowledge from web-site domain experts and to derives a causal relationship of knowledge. Specially, in our study, describes method of developing and building causal map, and suggests guide line of this method on practical application. This research results show that web-site flow starts "direct searching" or "interesting of special issue(domain)", and when challenges of web-site were accorded with user's skills web-site flow grows. Further, in the web-site, information searching intention results in increase of user's duration time and experience flow to discovery new interesting issues in this process. If user's web-site of interaction is increased, awareness of environment conditions decreased, finally, user's telepresense results in increased web-site flow. This paper contained thai this method make used of measuring flow in the web-site and developing of practical strategy.

Because of the proliferation of web services through web site, web hacking attempts are increasing using vulnerabilities of the web application. In order to improve the security of web applications, we have to find vulnerabilities in web applications and then have to remove. This paper addresses a vulnerability in a web application on existing problems and analyze and propose solutions to the vulnerability. This paper have checked the stability of existing web security solutions and evaluated its suitability through analysis of vulnerability. Also, we have implemented the vulnerability analysis tools for web Proxy system and proposed methods to optimize for resolution of web vulnerabilities.

Plastic strength analysis using plastic failure mode as a limit state is adopted instead of a conventional elastic structural analysis to predict the ultimate strength of Web frame idealized by a plane frame. Linear programming arid Compact procedure are developed for determining the collapse load factor. It is found that the final results are good agreement with the results of Elasto-plastic analysis. Besides, the redundant structures like Web frame is known to have multiple failure modes. Web frame may collapse under any of the possible failure modes. Thus, the identification of these possible failure modes is necessary and very important in the reliability analysis of Web frame. In order to deal with multiple failure modes, automatic generation method of all failure modes and basic failure modes is used for selecting the dominant failure modes. The probability of failure pastic collapse of Web frame is calculated using these dominant failure modes. The safety of Web frame is asscssed and compared by performing the deterministic and probabilistic analysis.

Web applications typically interact with databases. Therefore, it is very crucial to understand which web components access which database resources when maintaining web apps. Existing research identifies interactions between Java web components, such as JavaServer Pages and servlets but does not extract dependencies between the web components and database resources, such as tables and attributes. This paper proposes a dynamic analysis of Java web apps, which extracts such dependencies from a Java web app and represents them as a graph. The key responsibility of our analysis method is to identify when web components access database resources. To fulfill this responsibility, our method dynamically observes the database-related objects provided in the Java standard library using the proxy pattern, which can be applied to control access to a desired object. This study also experiments with open source web apps to verify the feasibility of the proposed method.

The purpose of this study is to analyze systematically the characteristics and types of contemporary houses and to offer information concerning houses based on web database. This study deals with single-unit Korean houses designed by modern architects, which appeared in architectural periodicals and books published since 1990. This study sets three analysis criteria : general characteristics, morphological characteristics and functional characteristics of houses. Also, the web database including analysis contents is constructed to attain various information of the houses and results. The process of constructing the web database and the search method for house information retrieval are described. It is concluded that contemporary houses show various aspects of their plans in certain specific types. By using web database we obtained various analysis on house plan. This study investigated practicality of web database in architecture, interior design and house studies, and the types of contemporary house plans are revealed as well.

웹 서비스와 웹 프로세스(Web Processes)는 다양한 시스템 상에서 이종의 소프트웨어 컴포넌트들을 효과적으로 통합할 수 있는 기술이다. 웹 서비스의 활용이 증대함에 따라 성능(performance), 비용(cost) 등 005(Quality of Service)는 서비스 제공자들 간의 차별화를 위한 요건으로 그 중요성이 증가하고 있다. 본 논문에서는 웹 서비스 성능 분석 도구인 sPAC(Web Service Performance Analysis Center)을 소개하여, 웹 서비스 조합시 성능의 만족 여부를 미리 고려할 수 있음을 보인다. sPAC은 1) 그래픽 기반 웹 프로세스 구성 환경을 제공, 2) 경부하(light load) 조건에서의 성능 테스트를 위해 웹 서비스를 호출, 3) 웹 프로세스에 대한 시뮬레이션 모델을 자동 생성 하여, 과부하(heavy load) 조건에서 시뮬레이션 기반의 성능 분석 수행, 4) 웹 서비스의 성능 분석 결과와 평가 데이터의 보고서 생성을 제공한다.

IT and e-business is a hot issue of the world business and economic communities. The web site is the portal through which most of electronic transactions are conducted today. The main purpose of this paper is to investigate on factors influencing the web site development at the firms in Korea. Survey questionnaires were distributed via email & post to 281 firms that have implemented web site. Out of 44 responded questionnaires, 39 data sets were available for statistical analysis with SPPSSWin 10.1. Factor analysis identified five dimensions of web site development : (1) support of top management, (2) information technologies maturity, (3) strategic utilization of web site, (4) strength of rivalry among competing firm, (5) support policy of the government. Results of this study show that information technologies maturity and strategic utilization of web site positively influence on web site development. But support of top management, strength of rivalry among competing firm and support policy of the government don't influence on web site development. This study may provide a guideline to improve the quality of web site development.

Since web has been used as the front-end of database, many web database connectivity tools have been developed and being developed now. For web developers and educators, it has been a difficult problem to select one tool out of so many alternatives. This paper compares web database connectivity tools available on PC Windows environment in the viewpoint of developers and educators. This comparative analysis focuses on the functions and programming techniques provided by these tools through implementing a simple case study using these software solutions. The performance analysis of these tools was not done in this reason.

In this paper we investigate a trend analysis service using Semantic Web technology in a news domain. The trend analysis service can provide more intelligent answers rather than the answer given In current news search engines since it can analyze the passage of time and the relation among news. In order to provide the trend analysis service, the capability of temporal reasoning is required, but the Semantic Web language such as OWL does not support the reasoning capability. Therefore, we propose a language TL-OWL(Temporal Web Ontology Language) extending OWL with the temporal reasoning.
