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.

We evaluated structured web site contents construct method. The method for construction web contents was considered. The construction procedure is as follows. Elicit "user requirement" and the web management side needs. Mark a check where each line and row corresponds to clarify the relation between both in the matrix by which user requirements and the purposes are arranged in lines and rows. To understand the systematic feature of the web site itself, "grasping information" and "structuring" are necessary. We actually constructed web site contents of a theatrical company using this method. and we got the construction of existing web site contents of another theatrical company. We compared our constructed web site contents with the existing web site contents. Finally, we evaluated this method and testified that this method is useful.

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.

그 동안 이루어진 웹 캐싱에 대한 연구주제는 캐시에 대한 구조적인 접근을 통한 성능의 향상과, 캐싱 기법 자체에 대한 연구, 이들 기법을 혼합적으로 결합한 기법에 대한 연구가 주로 이루어져 왔다. 또한 기존의 웹 객체 참조특성 분석은 웹 로그를 통한 히스토리 분석, 사용자선호도, 데이터마이닝 관점에서의 사용자 특성을 위주로 이루어져왔다. 본 연구에서는 웹 객체참조특성을 확률분포적인 특성 관점에서 분석하며, 이를 통해 객체의 평균수명을 분석하고 이를 웹 캐싱 성능 향상에 도입하는 새로운 연구 방법을 제시한다. 본 연구는 다양한 연구로 발전할 수 있으며, 전자상거래시스템의 성능향상, 지연시간 계산을 통한 고객 만족도의 향상, 웹 로그분석을 통한 데이터마이닝 분야 등 다양한 분야에 대해 연구의 파급 효과가 기대된다.

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.

본 논문에서는 웹 페이지 운영자가 웹 서버에 패스워드로 보호된 웹 영역을 배치시키는데 편리함을 제공하는 목적으로 새로운 패스워드 인증 방안을 제안한다. 이 방법에 따라 웹 영역은 접근 제한된 웹 페이지가 저장된 웹서버의 보안 디렉토리에 연결된다. 패스워드는 보안 디렉토리의 이름을 생성하는데 사용되며, 자바스크립트 코드는 보안 디렉토리영역 외부의 인증 웹 페이지에 포함된다. 이 스크립트 코드는 사용자가 입력한 패스워드를디렉토리 이름으로 변환시키고, 보안 디렉토리 내부의 접근 제한된 웹 페이지를 지시하는 완전한 URL을 형성한다. 따라서, 패스워드를 아는 사용자만이 유효한 URL을 구성할 수 있고, 접근 제한된 웹 페이지를 검색할 수 있다. 이 방법에 따라, 웹 페이지 운영자는 서버 독립적인 방식으로 패스워드로 보호된 웹 영역을 배치할 수 있다.

Recently, the quantity of information that is accessible from the Internet is being dramatically increased. Searching the Web for useful information has therefore become increasingly difficult. Thus, much research has been done on web robots which perform internet information filtering based on user interest. If a web site which users want to visit is found, its content is searched by following the searching list or Web sites links in order. This search process takes a long time according as the number of page or site increases so that its performance need to be improved. In order to minimize unnecessary search with web robots, this paper proposes an efficient information collection system based on compare and merge method. In the proposed system, a web robot initially collects information from web sites which users register. From the next visit to the web sites, the web robot compares what it collected with what the web sites have currently. If they are different, the web robot updates what it collected. Only updated web page information is classified according to subject and provided to users so that users can access the updated information quickly.

그 동안 활자인쇄매체의 타이포그래피의 적용에 관한 연구는 활발하였고 또 그 연구를 바탕으로 디자인에 적용되어 왔다. 그러나 지면출력을 위한 편집디자인이 아닌 Web환경에서의 가상공간의 편집디자인을 활자인쇄매체에 적용되는 방법을 그대로 이용하고 있는 것이 현실 이였다. 그래서 본 논문에서는 Web상황에 타이포그래피을 적절히 적용시키기 위한 방법으로 리서치를 통한 Web상황에서의 바람직한 타이포그래피의 적용방법과 타이포그래피의 적용 한계점을 알아보고 그 것에 대한 대체방안을 논하고자 한다.

In this paper, we propose to new dispatcher method, which doesn't depend on an operating system of the server, and the direct routing method, by which a server answers a client's request at first hand. And, propose new web clustering scheme based on the contents on the web where web servers composed of cluster, with each different contents, answer client's request. The other purposes are to reduce overhead of the dispatcher through load balance, and to minimize the time to take in responding to a client's request. The performance of new web cluster scheme was improved by about 39% than that of the existing RR method. It was identified that the performance of the proposed web cluster method was extraordinary improved comparing with that of the existing RR method as a whole.
