  • 데이터베이스에 저장되어 있는 데이터를 그리드 시스템에서 사용하기 위해서는 먼저 시스템에 필요한 데이터를 수집하여 데이터베이스나 파일 시스템에 저장한 후, 데이터베이스의 데이터 및 그 인덱스를 관리하는 전용의 모듈을 별도로 구현하고, 그리드 시스템에 연동시켜야 한다. 웹 기반의 데이터 검색 시스템을 구현하여 데이터베이스에 있는 데이터들을 그리드 시스템에서 바로 사용할 수 있다면, 전용의 데이터 모듈 없이 그리드 시스템에서 바로 데이터를 처리할 수 있으므로, 보다 효율적이고 사용하기 쉬우며, 데이터베이스의 변경에 유연하게 대처한 수 있을 것이다. 본 논문에서는 웹 기반 데이터베이스의 데이터를 바로 그리드 시스템과 연계시켜 사용한 수 있는 검색 시스템을 제안한다. 이 검색 시스템을 이용하여 버추얼 스크리닝 작업을 수행하는 바이오 그리드 시스템에 적용하여 UB Grid (Universal Bio Grid)를 구축하였다. 개발자는 웹에서 제공되는 데이터론 그리드 시스템에 통합시키기 위한 시간과 노력을 줄일 수 있었으며, 사용자는 보다 쉽게 효율적으로 UB Grid 시스템을 사용한 수 있었다.

  • Recently XML (eXtensible Markup Language) is becoming the standard for exchanging the documents on the web. And as the amount of information is increasing because of the development of the technique in the Internet, semantic web is becoming to appear for more exact result of information retrieval than the existing one on the web. Ontology which is the basis of the semantic web provides the basic knowledge system to express a particular knowledge. So it can show the exact result of the information retrieval. Ontology defines the particular concepts and the relationships between the concepts about specific domain and it has the hierarchy similar to the taxonomy. In this paper, we propose the generation of semi-automatic ontology based on XML documents that are interesting to many researchers as the means of knowledge expression. To construct the ontology in a particular domain, we suggest the algorithm to determine the domain. So we determined that the domain of ontology is to extract the information of movie on the web. And we used the generalized association rules, one of data mining methods, to generate the ontology, using the tag and contents of XML documents. And XTM (XML Topic Maps), ISO Standard, is used to construct the ontology as an ontology language. The advantage of this method is that because we construct the ontology based on the terms frequently used documents related in the domain, it is useful to query and retrieve the related domain.

  • 최근 인터넷에서 사용되고 있는 하이퍼텍스트 생성 언어(HTML : Hyper Text Markup Language)는 제한된 태그(Tag)들을 사용하기 때문에 문서를 구조화시키지 못해 정보 축적과 정의추출 방법이 비효율적이고 추출한 정보의 가공이 어렵다. 그러나 확장성 생성 언어 (XML ; eXtensible Markup Language)는 사용자가 문서상에 사용될 태그를 자유롭게 정의할 수 있고 다른 사람들도 그 태그를 사용할 수 있기 때문에 HTML에 비해 정보 축적과 정보추출 방법이 용이하다. 서로 다른 데이터베이스를 사용하고 있는 항만 관련 업체들간의 물류에 관한 정보를 공유하거나 교환하기 위해서는 HTML이 아닌 XML이 더 적합하다. 본 논문에서는 항만업체들의 요구를 수용하기 위해 XML을 이용하여 웹에서 이기종 데이터베이스 관리 시스템(DBMS ; Database Management System)간의 데이터 복제 및 정보를 교환할 수 있는 웹 에이전트 시스템을 설계하고 구현하였다.

  • Material selection is one of the important activities in design and manufacturing. A selected material at the conceptual design stage affects functionality of the designed part as well as manufacturability and cost of the final product. Unfortunately there are not many accessible material databases that can be used for design. In this research, a web-based material database was constructed. In order to assist designers to compare different materials, two-dimensional and three-dimensional graphs were provided via the web browser Using these graphical tools, multi-dimensional comparison was available in more intuitive manner. As a case study, this system was applied for material selection of an automotive engine pulley.

  • Our society becomes complex because technology is developing quickly. Especially, building services field deals with the important information that produces a drawing and manages the planning information and manpower. Therefore, the efficient management that connected with the construction information plays the important roles. The study develops a database by organizing systematically the various types of information using hypermedia. And, this study is to build the management system that can serve the various information that operated by DBMS on the web according to the DB structure. The information database was developed using internet web technology for building services field.

  • Understanding the consumer changed life styles are integrated, mutual complement for user's worth and consciousness, the life of consumption, etc. Recently, Apartment Model House has built for distribute to Apartment house When they enter the units after 2 or 3 years. So, Interior designer make an inference from the changed life styles. But, We don't have enough information to trace the design trend about residential space design. Design database is correspond with interior space and structured entity relationship. There are three parts in this Database, Type, Elements and Relation information. Type are composed size, ages, style, and space, Elements are materials and space elements. Relation information are publishing, designer, exhibition, construction company, remodeling, Intoner design and User favorite styles are the development in web environment. This research supplies interior design information for Web environment and trend analysis supports collaboration with development of interior design information database.

  • Materials property data are necessary to secure the reliability of failure prevention techniques such as inspection and remaining life assessment of civil infrastructure and industrial facilities. However, there is no properly collected data in Korea, and those foreign data are hard to use because of the scattering of the sources, the difference of standards, etc. In this paper, materials property database system which has been constructed at Korea Research Institute of Standards and Science is introduced. Constructed database contains 145,000 numeric data of materials property for 600 kinds of metals and can be retrieved on the internet. The database system provides graphical user interface-based information searching functions necessary for the life evaluation and safety analysis.

  • Satellite images are utilized for various purposes and many people are concerned about them. But it is necessary to process geometric correction for using of satellite images. However, common user regards geometric correction, which is basic preprocessing for satellite image, as laborious job. Therefore we should provide an automatic geometric correction method for Landsat image using GCP chip database. The GCP chip database is the collection of pieces of images with geoinformation and is provided by XML web service. More specifically, XML web service enables common users to easily use our GCP chip database for their own geometric correcting applications.
