본 연구는 현 Inner-Wear매장에서 판매되어지는 제품을 소비자가 선택할 수 있는 한계 즉, 시각적인 연에 국한된다는 것에 착안하여 현실이 아닌 가상공간에서의 구매. 즉 물리적 현실적 제약으로부터 현재 존재하지 않는 미래의 상황을 연출, 미리 볼 수 있도록 가상의 상황을 입체적으로 연출하여 Inner-Wear를 쉽게 착용하고 그 모습을 자유롭게 검색하여 볼 수 있도록 하고자 한다. 자신의 신체를 만들어 보고 자신이 구매하고자 하는 제품을 골라 가상공간에서 자신의 신체에 직접 입혀보며 자신의 신체에 얼마나 잘 맞는지 직접 확인해 보고 구매 할 수 있도록 하는데 있다. 이 시스템은 Web상에서 구동 할 수 있도록 구현되어 일반 소비자들이 어디서나 사이트에 접속하여 구매 할 수 있도록 할 것이다.

본 고에서는 소재분야의 기술수준을 정확히 파악하고, 앞으로 나아갈 R&D 정책방향을 설정하는 데 도움이 되도록 하기 위해 NS(National Science Indicators) DB와 Web of Science DB의 재료과학(Materials Science) 분야를 토대로 논문분석을 수행하였다. 최근 10년간(1999-2008년) 소재 분야에 대한 분석결과 양적 지표인 논문수는 연평균 12%로 지속적으로 증가하였으며, 세계순위는 1999년 9위에서 2008년 4위까지 상승하였다. 질적지표인 논문1편당 피인용횟수는 세계 평균 대비 1999년 94.7%(한국 9.35건, 세계 9.87건)에서 2008년 88.4%(한국 0.23건, 세계 0.26건)로 낮아진 것으로 나타났다. 최근 10년간 연구주체간 협력 논문수를 살펴보면 대학-대학간 이 4,337편(39.8%)으로 가장 많으며, 대학-공공연구기관간은 3,135건(28.8%), 대학-기업은 2,295건(21.1%)으로 전체의 약 90%를 차지하고 있다. 또한 해외 협력논문수는 전체 논문에서 약 26%를 차지하고 있다. 결과적으로 기초연구성과의 실용화 연계 지원책 마련, 질중심 논문평가의 강화, 국내외 협력주체간 협력 연수의 강화, 주기적 논문분석을 통한 소재 R&D 정책 수립 및 연구사업기획에의 활용강화 필요하다.

전국의 궁도인구는 만 여명에 이른다. 매년 1~2주를 주기로 개최되는 이 대회는 참가접수부터 운영까지 오로지 오프라인으로만 진행되어 경기외적인 비용과 시간이 상당히 낭비된다. 이에 본 연구에서는 이용자의 접근성이 향상되고, 플랫폼에 독립적인 웹기반의 경기지원시스템을 구현하고자 한다. 시스템에 접근하는 이용자는 접수와 결과를 확인하는 대회 전/후에 집중되므로 이 때의 효율적인 DB Access 기술이 필요하다. 따라서 본 논문에서는 DBCP 기술을 이용하여 DB Connection부분에서 보다 효율적인 시스템으로 개발하고자 한다.

In this paper, an objective of this research is to add convenience to the intranet operating within an educational institution, by setting up a messenger function to enable the faculties and teachers to make better use of the university database via Intranet. With this messenger services, the users can view the information about the members in a group they belong to, and register as friends a group of members they selected from the work group they are in. This function will reduce the cumbersome chores of adding one individual as a friend at a time. This research will enhance the Intranet within an educational institution by integrating new functions. Speciallly, In this paper, it is stored student data by the input form by the JDBC of XML standard data. Also, it is able to search of stored database to web sever from web client by the SQL quary.

We collected eleven large astronomical catalogues, which include 2MASS, USNO B1.0, GSC 2 catalogues and so on. Most of these catalogues are the frequently used by astronomers for all sorts of applications. But the researches are faced with the problem of accessing these databases because these catalogues contain from tens millions up to thousands of millions of records. So we developed a web application system to manage these large catalogues, the main purpose of the web application is to allow a powerful and efficient querying activity on these catalogues through internet by using a simple web interface. User could retrieve the query result in variety of formats including plain text, HTML, Microsoft Excel format (XLS), and VOTable. Furthermore, user also could display and analyze result graphically by using a powerful interactive visualization tools named VOPlot which was developed by the Virtual Observatory-India (VOI) project.

The coast has been known as very vulnerable area. This area has nature disasters such as typhoon, tidal wave, flood and storm almost every year. In this study, coast vulnerable area information management system was developed to manage the coastal facilities and vulnerable area through Web GIS. This system is able to visualize the damage area and support the official work related to coast as efficient DSS(Decision Supporting System). Moreover, the foundation for domestic coast information management is expected by acquiring less cost and time. For this, GIS DB was first constructed by acquiring damage factor data such as typhoon, tidal wave, flood and storm. Then GIS analysis methods and high resolution satellite images are used to possibly present the results of retrieve as table, map, graph, inundation simulation in real time.

Major corporations and portals have implemented a link server that connects Content Management Systems (CMS) to the physical address of content in a database (DB) to support efficient content use in web-based environments. In particular, a link server automatically connects the physical address of content in a DB to the content URL shown through a web browser screen, and re-connects the URL and the physical address when either is modified. In recent years, the number of users of digital content over the web has increased significantly because of the advent of the Big Data environment, which has also increased the number of link validity checks that should be performed in a CMS and a link server. If the link validity check is performed through an existing URL-based sequential method instead of petabyte or even etabyte environments, the identification rate of dead links decreases because of the degradation of validity check performance; moreover, frequent link checks add a large amount of workload to the DB. Hence, this study is aimed at providing a link server that can recognize URL link deletion or addition through analysis on the B-tree-based Information Identifier count per interval based on a large amount of URLs in order to resolve the existing problems. Through this study, the dead link check that is faster and adds lower loads than the existing method can be performed.

A web page was developed to enhance students' learning experience in studying meteorological phenomena. After collecting the meteorological elements observed with automatic weather observation system (AWS), it serve real-time meteorological information on demand. Past meteorological information as well as real-time current information can be retrieved because the web page can save and accumulate observed information in its data base. The completed web page was successfully applied in school settings in teaching students meteorology research sections of earth science. The results show that students experienced authentic and meaningful learning through the real-time meteorological information from the web page. In addition, large scale of time was required to observe meteorological phenomena and it hindered practical meteorological research in earth science classes. However, it is expected that the time limitation can be overcome by utilizing accumulated meteorological information of the web page.

This research is a case study that describes the NUCLIS21(Nuclear Information System 21), an integrated web-based information management system of KAERI(Korea Atomic Energy Research Institute), implemented to carry out the role of a national nuclear information center with government support as an information infra implementation programme. Through its user-centered single interface, the system aims at building an infrastructure for the national nuclear information center, as well as improving the information management system of the TID(Technical Information Department) within the institute. The system consists of two major parts which are an integrated module of the MIS and six different kinds of system. These include the Integral search system with OPAC, My Library, the Acquisition system, the Catalogue system, the Information Supply system, and the Serial Publication system. The DB is composed of Bibliographical DB, Original text DB and Abstract DB. A special feature of this system was designed as a unified network system through connection to MIS(Management Integration System) of the institute, so users can get research information for projects. Therefore, they have access to available information easily and access to the ongoing service of this system. Furthermore, users can share information by using our system. The survey has it that 75.7%(200 persons), 62.1%(164 persons) and 78.4%(207 persons) of the respondents are satisfied with the fidelity, speediness, and convenience of the system respectively, and the overall satisfaction of the respondents is comparably high.
