Domestic information service authority and company provide database services to introduce the newest scientific and technological information, trend, and research data. Among many databases, FSTA((Food Science and Technology Abstracts)) is a bibliographic database providing worldwide coverage of all scientific and technological aspects of the processing and manufacturing of human food products. To service FSTA database through KRISTAL search engine developed by KISTI(Korea Institute of Science and Technology Information) need many process such as data obtainment, building, search, modification, rebuilding, and statistics. In this paper, we present implementation of management tool used to build FSTA database effectively. The management tool provides graphical user interface and controls all process from data obtainment to building of KRISTAL information searching system. By building FSTA database fast and accurately, user can get information that they want to find from the newest FSTA database.

일반적으로 Oracle과 같은 RDBMS에서 클라이언트가 데이터베이스를 접근하거나 관리하기 위해서는 RDBMS 서버에 리스너가 실행되어야 한다. 리스너는 네트워크를 이용해 클라이언트에서 서버로 연결하기 위한 네트워크 관리자로서, 수행정보의 전송 및 관리 기능을 수행한다. 이에 반해, 정보검색시스템에서의 시스템 기동 및 폐쇄, 데이터의 관리는 온라인이 아닌 오프라인 작업으로 이루어지는 것이 보통이다. 이는 각 시스템이 추구하는 것이 관리와 검색으로 각각 다르기 때문에 구조적인 차이가 존재한다. 정보검색관리시스템 KRISTAL은 기본적으로 정보검색엔진기반의 DBMS를 적용하였기 때문에 데이터베이스 관리도구 자체가 엔진과 밀결합된 형태가 아닌, 별도의 API로 제공되기 때문에 클라이언트가 온라인상으로 서버에게 관리 기능을 요청할 수 없는 단점이 있다. 이에 본 논문에서는 KRISTAL기반 데이터베이스 관리를 위한 KRISTAL 리스너를 제안한다. KRISTAL 리스너는 RDBMS 리스너의 일반적인 기능뿐만 아니라 KRISTAL 데이터베이스 검색 데몬 프로세스 관리, 스키마 및 테이블 관리, 백업관리, 분산검색 데몬 등 온라인으로 KRISTAL 서버를 제어할 수 있는 관리 기능을 제공한다.

Many institutes and organizations carrying out the national R&D projects have and use the expert pool database at each need. But there is lack of human resources information about expert in science and technology part for many policy planning and committee activity, also most of the expert pools are scattered on several database systems. So it is necessary to manage systematically the human resources informations about scientific expert. As the committeeman assignment and committee findings management are conducted by the off-line method, there are wastes of time and labor in committeeman assignment process and committee history management. Therefore we need to provide an effective and automatic process for committeeman assignment and management. In this paper, we construct a database for expert pool who can be used in committee activity or policy planning, and implement a system that services committee management and committeeman assignment process. The human information retrieval service of this system is based on the KRISTAL-2002, an information retrieval and management system developed by KISTI.

한국과학기술정보연구원은 국가 과학기술 지식정보인프라의 중심기관이자 과학기술종합정보센터로서 논문, 특허, 연구보고서, 사실정보, 생물다양성정보 등을 비롯한 다양한 종류의 과학기술관련 데이터베이스를 구축, 수집 및 서비스 하고 있다. 그러나 이러한 정보들은 약 40여개의 웹사이트에 분산되어 서비스되고 있어, 하나의 서비스 접점에서 다양한 정보를 쉽고 편리하게 얻고자 하는 이용자들의 요구를 만족시키지 못하고 있다. 따라서 본 논문에서는 분산 서비스되고 있는 대용량의 이기종 과학기술관련 데이터베이스를 각 데이터베이스의 특성을 고려하여 효과적으로 통합검색 될 수 있도록 하는 통합검색 데이터베이스 구축시스템을 설계한다. 본 논문의 통합검색시스템은 KISTI에서 자체 개발한 정보검색관리시스템인 KRISTAL-2002를 사용한다.

A late-comer in the marine affairs, development of ways for efficient access and utilization of information on marine environmental conservation and pollution prevention is important. The properties and removal methods of toxic chemicals have been entered into the database for 1,000 substances. The database of toxic chemicals for pollution and spills has also been fortified for the following terms: general characteristics, health hazard and response, fire hazard and response, chemical reactivity, physico-chemical properties, and other properties. The information and data running in this database are easily accessible via Internet and Korean telecommunications companies; it is also available KRISTAL databases.

In this paper, we propose an integrated information retrieval system for distributed multiple KRISTAL-2002 systems by using the metadata information. This system integrates current systems for different areas or systems for the same area with the different schemas so that the users can get the answers by once from the whole systems. The proposed system composes of the Source Server Manager(SSM) supporting the mapping between the integrated metadata database and source server, the Integrated Metadata Manager(ISM) for registering and managing the metadata and schema mapping, the Distributed Query Processor (DQP) for processing the user query into the source server query, the Distributed Data Set Integrated Manager(DDSIM) for transforming the total retrieval results by merging to the HTML format, and the integrated retrieval engine for managing the query results. It is assumed that the integrated metadata follows ISO/IEC 11179 metadata registration procedure with the metadata registry system which is a subsystem of the proposed system. There are two kinds of queries for users; the basic query and the detailed query. The users may select the databases or organizations for results by their own choices before giving the queries. The proposed system has been developed over KRISTAL-2002 systems with $Visual C^{++}\;and\;C^{++}-CGI$ and tested and verified with the six database systems.

Among biological information, GenBank, provided by the National Center for Biotechnology Information (NCBI)of the United States, is a representative database on genetic information and is the most widely used by researchers around the world. Korea Institute of Science and Technology Information (KISTI) visits NCBI on a regular basis and downloads the latest version of GenBank to reorganize the information gathered there into a database. This database is provided for Korean researchers of science and technology through the Bio-KRISTAL search engine, developed by KISTI. This study aims to design a service model that links information on papers, patents, and biodiversity and other contents of NDSL, an integrated service on scientific and technological information run by KISTI, with GenBank's reference and organism fields and to develop a prototype system. For this purpose, this paper explores the possibility of a linkage and convergence service between heterogeneous content by: (a) collecting GenBank data from NCBI's FTP site; (b) dividing GenBank text files into basic and reference genetic information and restructuring them into a database; (c) extracting article and patent information from the GenBank reference fields to generate new tables; and (d) leveraging data mapping technology to implement a prototype system where GenBank and NDSL data are interlinked and provided.

It constructs a database generally and service it does, to use a commercial business DBMS that manages information and to use a retrieval system that supports a search, it adopts the gearing method of the DBMS and information retrieval system. But like this method is inconvenient must operate the DBMS and information retrieval system with duplication to be, there is a weak point where the data management and processing become accomplished with duplication. It presents the DB construction and information search and the management model of the KRISTAL-2002 information retrieval and management system base for the scientific and technical information data management and processing from the dissertation which it sees.

Today information is important for man and total fields. Science field is not exception. Currently information age things of information is only useful for man and total industry. So bioinformation is necessary of biodiversity in broadly wide and detailed information. Among information, bioinformation of biodiversity is important and utilization of living things. Among them, the mushroom(higher fungi) are an important part in ecosystem as a decomposer responsible for recycling materials. Many living things today, however, have endangered by environmental pollution and ecological destruction. The higher fungi also are not exception. Mushroom has been used for food sources, pharmacy and forests resources from ancient times. Among biodiversity, database of mushroom is very necessary for university, institute and industry. This DB contains four items of native mushroom(higher fungi) from Korea. first item contain species, genus, family, order class, ad division according to the classification. Second item contain pharmaceutical purpose, food source, culture, toxic, anti-cancer of the application. Third item contain symbiosis, rotten trees of the ecological resources. Fourth item contain geographical distribution and illustrated literature. Information system is also available using KRISTAL II for searches on the WEB in URL http://ruby. kisti. re. kr/∼mushroom.
