NGIS사업의 일환으로 1995년이래 수행중인 지하시설물전산화 사업의 확대시범도시에 포함된 19개 지자체는 2003년 과업종료에 따라 상하수도 중심의 지하시설물 DB를 활용한 지하시설물 유지관리시스템의 실질적인 운용에 대비하고 있다. 그러나, 각 지자체의 상하수도 유지관리업무를 담당하는 부서는 전산화 환경에서 지하시설물 DB의 유지관리를 담당할 수 있는 전문인력 및 관련 기술과 경험부재로 인해 기존의 현장 수작업 방식으로 지하시설물 DB를 유지관리할 경우 자료누락, 오기 및 이기오류, DB의 최근성 확보 등의 문제로 인하여 지하시설물 DB의 품질저하가 우려되고 있는 실정이다. 따라서 본 연구에서는 지하시설물 DB 유지관리 방법론 개발의 선행 연구로 지자체 상하수도 유지관리업무를 담당하는 현장 작업자의 업무환경을 전산화 환경으로 전환하기 위하여 현장업무용 모바일장비 활용성 실험과 국내 무선통신 환경분석 및 모바일장비용 GPS수신기 활용성 실험을 수행하여 현장 업무용 모바일 작업 환경을 구축하였다. 지하시설물 DB의 효율적인 유지관리 방법론 개발에서는 국내 무선통신환경의 제약에 의해 편의상 업무빈도가 높고 정기적으로 수행되는 정상업무에 대해서는 OFF-LINE방식의 DB 수정/갱신 방법론을 개발, 적용하고, 부정기적이나 처리에 시급성이 요망되는 긴급업무에 대해서는 ON-LINE 방식의 DB 수정/갱신 방법론을 개발, 적용하였다.

The work environment of locomotive cabs has long been an important issue in the design of railload systems since it is quite critical in terms of system's operational safety. It is getting more attention as the running speed of the trains goes up these days. To this end, this paper describes how to systematically construct a DB for the requirements set in the course of the improvement process for the aforementioned cab work environment. As a solution approach, we have adopted the requirement architecture concept to cover the whole activities required to do such as in requirements generation, DB construction, change management, and traceability management. Specifically, based on the requirement architecture framework a requirement process to collect requirements for improvement is discussed, and the guide lines are suggested for verification and validation of the developed requirements. In addition, a base schema and requirements templates are developed, which will be used in generating requirements and constructing a DB. Finally, it is demonstrated how the requirements DB for locomotive cabs can be constructed using a computer-aided tool in an integrated fashion.

본 연구는 GIS와 지리정보 DB가 지역계획이나 도시계획을 위한 단순한 기능적 도구가 아니라, 지역발전을 촉진하는 지역정보기반으로서 구축되어야 함을 전제로 하였다. 이를 위하여 국내외의 지리정보 DB 구축사례를 분석하고, 정보사회에서 GIS가 수행해야 할 역할을 분석하였다. 이를 바탕으로 지역개발과 연계되는 지리정보 DB가 구축되기 위해서는 지리정보의 내용적 기술적 제도적 변화가 이루어져야 함을 서술하였다. 즉, 향후의 지역 지리정보는 내용적으로는 다양화, 충실화, 기능화되고, 기술적으로는 메타자료의 구축, 사용자 중심의 인터페이스, DB구조의 유연성을 갖추어야 하며, 제도적으로는 유통체계 확립 민관 정보공유, 지리정보 공개 등이 보장되어야 한다.

WPS/PQR is the essential documents for shipbuilding welding. WPS is the document containing the information related to welding procedure and PQR is the record of approval for welding procedure. Both documents should be approved by the ship owners and the classification societies. It is very important to manage these documents because the welding procedure using these documents could not be carried out before they are approved. Database is an useful tool to manage these documents. It can manage a number of documents and show the processing status of WPS/PQR documents. In this study, all documents related to WPS/PQR documents were investigated and analyzed in the viewpoint of DB. An appropriate DB system was designed for WPS/PQR and the related documents on the basis of CBD methodology. The DB system could make WPS/PQR documents easily and shortly. The grasp of the processing status of WPS/ PQR could help the good management of fabrication schedule in shipbuilding.

본 연구의 목적은 1) 소설 속 지명 데이터베이스(DB)를 구축하고, 2) 확장 가능한 지명 DB를 위해 자동으로 지명을 추출하여 데이터베이스를 갱신하며, 3) 데이터베이스 내의 소설지명과 용례를 검색하고 시각화하는 파일럿시스템을 구현하는 데 있다. 특히, 학습자료(training)에 해당하는 말뭉치(corpus)를 확보하기 어려운, 소설지명과 같이 현재 잘 쓰이지 않는 개체명을 자동으로 추출하는 것은 매우 어려운 문제이다. 효과적인 지명 정보 추출용 학습자료 말뭉치 확보 문제를 해결하기 위해 본 논문에서는 이미 수작업으로 구축된 웹 지식(어휘사전)을 활용하여 학습에 필요한 충분한 양의 학습말뭉치를 확보하는 방안을 적용하였다. 이렇게 확보된 학습용 코퍼스와 학습된 자동추출 모듈을 가지고, 새로운 지명 용례를 찾아 추가하는 지명 데이터베이스 확장 도구를 만들었으며, 소설지명을 지도 위에 시각화하는 시스템을 설계하였다. 또한, 시범시스템을 구현함으로써 실험적으로 그 타당성을 입증하였다. 끝으로, 현재 시스템의 보완점을 제시하였다.

Recently, amount of High-Rise Mixed-use Building is Increasing based on Preference of comfortable residence and good view. Government policies were turned to prefer about High-Rise Mixed-use Building because of decreased real estate Condition. But these changes have revealed that it has many maintenance problems for example- efficiency, economic, environmental problems. This paper suggests that the Database System based on various alternatives and real case. And it will be a tool in the scientific decision and value analysis from the facility management to make optimized decision.

City Train Technology that is large and complex system and consists of mechanical, electronic, electric, materials, computer, communication, civil/track etc. is very important area of railway industry, national fundamental industry. The standardization of city train system as a public transportation method and foundation of national economy is very important in order to do effective operation and to get fundamental technology, and the information system of the standards is required to operate the city train system effectively. By building data base of city train system design knowledge using computer-aided system engineering tool-Cradle, the system development issues and the design solutions are used by all engaged persons, and are managed by modeling and documentation. And this system will support architecture design consistently and effectively by applying this system to formalize early development process, to system requirements and configuration management, to system interface analysis and management and to system behavior analysis etc.. This study is for construction of data base of system design knowledge through making data base of many kinds of standards using CASE tool based on System Engineering Process, and introduces a model to support concurrent engineering for all engineers involved in system development allowing access to standard DB through Web from anywhere and at anytime.
