The people information is distributed in various forms such as database, web page, text, and so on, where the world wide web is one of the main sources of publicly-available people information. It has a characteristic that the information on people is intrinsically temporal. Therefore, the reconstruction of the information is needed for an individual or a company to use it efficiently. In order to maintain or manage the temporal people information, it must distinguish the variable information from invariable information of people. In this paper, we propose a method that constructs an ontology based on events to manage the variable people information efficiently. In addition, we present a system which reconstructs people information that satisfies the users' demand with the ontology.

In this paper, we highlight the development of a web application system. Its main objective is to provide pathway visualization functionalities for inter-cytokine relationships, as well as for other types of relationships, with a specific cytokine(s) of interest. A natural language processor is first used to extract information from a certain web page that concerns the cytokine(s) of interest. The results obtained are then further processed and then displayed graphically to the user. The system displays how the cytokine(s) of interest interacts with other cytokines and cells. Useful information such as the type of reaction and catalyst involved, if any, are also displayed. In addition, the system also offers functionalities for graphical manipulations of the visualized pathways. The system has been shown to provide better overview, and hence, improved learning to readers who are new to this field by virtue of accurate inputs obtained from the natural language processing module.

At present, more than 300 races of the Silkworm are conserved and used as valuable genetic resources. But because of the uneffectiveness of manual data management, faster and systematic data base construction is needed. So, development of silkworm genetic resources management program has been begun and the result can be practically used. When developing the program, Visual basic was used for data input system construction, and MS Access for database. IIS(Internet Information System) and ASP(Active Server Page) was also used for searching data and information with Internet Web Server and Web Browser which is comfortable for constructing database and providing information. Data input item consists of 46 practical characteristics such as race name, moltinism, larval period and pupation percentage etc.. And these characteristics are classified with qualitative and quantitative character. Photographs of silkworm, cocoon and other related items were scanned and the image data was recorded on the database.

본 논문에서는 다중 쓰레드 환경에서 동작하는 웹 크롤러를 구현하고 성능을 분석한다. 이 웹 크롤러의 특징은 검색시간을 단축하기 위하여 크롤링, 파싱 및 페이지랭킹, DB 저장 모듈을 서로 독립적으로 다른 작업을 수행하도록 구현한 것이다. 크롤링 모듈은 웹상의 데이터를 수집하는 기능을 제공한다. 그리고 파싱 및 페이지랭크 모듈은 수집한 데이터를 파싱하고, 웹 페이지의 상대적인 중요도를 수치로 계산하여 페이지랭크를 지정한다. DB 연동 모듈은 페이지랭크 모듈에서 구한 페이지랭크를 데이터베이스에 저장한다. 성능평가에서는 다중 쓰레드 환경에서 쓰레드 수와 웹 페이지의 수에 따른 검색 시간을 측정하여 그 결과를 비교 평가한다.

In this work, we compared several feature selection methods in the field of spam mail filtering. The proposed fuzzy inference method outperforms information gain and chi squared test methods as a feature selection method in terms of error rate. In the case of junk mails, since the mail body has little text information, it provides insufficient hints to distinguish spam mails from legitimate ones. To address this problem, we follow hyperlinks contained in the email body, fetch contents of a remote web page, and extract hints from both original email body and fetched web pages. A two-phase approach is applied to filter spam mails in which definite hint is used first, and then less definite textual information is used. In our experiment, the proposed two-phase method achieved an improvement of recall by 32.4% on the average over the $1^{st}$ phase or the $2^{nd}$ phase only works.

In the past several years there has been increasing the studies using ubiquitous technology as the base technology of IT-convergence. The cooltown, one of the ubiquitous projects, is based on the web technology and the mobile environment. However, in the cooltown system, users only get a pre-made web-page. In this paper, we propose the algorithm improved usability applying the context-awareness based on the sensor network. In this paper, we can provide a custom tailored service overlooked in the existing system from this.

In recent years, Internet/Intranet represents the next generation of computing environment. Therefore, it is necessary to integrate WWW((World Wide Web) over internet/intranet and DBMS(Database Management System) in proportion to the increase of various users' request and an amount of data variety. Also, also full variety of service over WWW need to accomplish rapidly modification of bug and make a betterment of system according to a feature of rapid change of information and an importance of interaction with users. The typical CGI method commonly used to connect with database has a disadvantage in time and resources in system due to frequent connection with database. Therefore, this paper provides the conceptual structure and implementation of information management system over WWW with applying a recent information technology called ASP(Active Server Pages) that controls and arranges client logic dynamically in server-side and introducing a concept of working group and folder to database design.

TCP/IP 프로토콜을 기반으로 한 웹은 컴퓨터 기술과 통신 기술의 발달과 더불어 양적으로나 복잡도에 있어서 놀라운 속도로 성장하고 있다. 이에 따라 웹 사이트를 이용한 홍보나 기업의 이익을 목적으로 하는 웹 사이트들이 급속히 증가하면서 웹 페이지들의 추가, 삭제, 갱신 등 끊임없이 일어나고 있다. 이렇게 끊임없는 웹 페이지의 수정으로 인하여 링크가 끊어지는 등의 문제가 발생한 수 있는데, 이런 끊어진 링크의 발견은 쉽지 않고, 때에 따라서는 기업에 큰 손실을 가져올 수 있다. 본 논문에서는 웹 페이지 문서들 사이에 존재하는 관계성(Relationship)과 제약 조건(Constraint Condition)을 확장 UML을 통해 정의하여, 웹 페이지의 DLP(Dangling Link Problem)를 해결하기 위한 WPMS(Web Page Integrity Management System) 시스템을 제안하였다.

When considering the use of rapid prototyping (RP), there are many issues a designer has to address for handling an STL model, the de facto standard fur RP. Today designers can skip all these issues by visiting web-based service bureaus that readily supply needed information for the RP services. Since orders are taken for RP parts through the web page of service providers designers are now asked to upload their STL files to the company server either by direct upload, ftp file transfer, or as an e-mail attachment. If the service bureau, however, fixes or edits an STL filceto optimize the RP process but neglects to tell its customer about the rework in detail, it may cause problems down the line in processing of the original CAD data for other applications. In this paper, we propose a framework for a collaborative virtual environment between CAD designers and RP processes on the internet which directly provides designers with an advanced preprocessor functionality, design visualization, as well as model display, repair, and slicing over the network. This can help smooth data transfer from CAD to RP process with minimum inconsistency in CAD.
