  • For the safe management of nuclear facilities, including a radioactive waste repository, data about the facility site and the surrounding environment must be collected and managed systematically. This is particularly true for a radwaste repository, which has to be institutionally controlled for a long period after closure. The objectives of this study are (1) to establish a systematical management plan for information about a radwaste repository site and its environment, and (2) to design a database management program for this information, based on the Relative Database Management System (RDBMS). The spatial data are designed by the geodatabase, which is a new object, based on the RDBMS, to manage spatial information related to the database. To meet this requirement, a new program called 'Site Information and Total Environmental data management System (SITES)' is being developed. The scope that produced from the first step of the present study for development of the SITES is introduced. The database is designed to combine spatial and attribute data, and is designed for the establishment of the Geographic Information System (GIS). The hardware and software systems are designed with consideration given to the total data management of the items within the radioactive environment.

  • Purpose : To implement the database system of oral and maxillofacial radiological images using a commercial medical image management software with personally developed classification code. Materials and methods : The image database was built using a slightly modified commercial medical image management software, Dr. Image v.2.1 (Bit Computer Co., Korea). The function of wild card '*' was added to the search function of this program. Diagnosis classification codes were written as the number at the first three digits, and radiographic technique classification codes as the alphabet right after the diagnosis code. 449 radiological films of 218 cases from January, 2000 to December, 2000, which had been specially stored for the demonstration and education at Dept. of OMF Radiology of Dankook University Dental Hospital, were scanned with each patient information. Results: Cases could be efficiently accessed and analyzed by using the classification code. Search and statistics results were easily obtained according to sex, age, disease diagnosis and radiographic technique. Conclusion : Efficient image management was possible with this image database system. Application of this system to other departments or personal image management can be made possible by utilizing the appropriate classification code system.

  • 건설 프로젝트의 초기단계에 타당성을 검토함에 있어서 공통가설공사의 경우 설계도서상에 표시가 되지 않거나, 시방서상에 간략하게 서술되어 있기 때문에 담당자의 경험 의존율이 다른 공종에 비해 높다. 이런 초기단계의 결전은 프로젝트의 진행과 더불어 많은 문제점들을 야기 시킬 가능성이 있다. 따라서 최근 활발히 논의가 되고 있는 기존 공사정보에 대한 실적 데이터베이스와 공통가설공사의 분류체계를 포함한 시스템을 개발하여 자료들을 분석, 활용함으로써 시공전(Pre-Construction) 단계의 공통가설공사에 대한 작업 및 원가 예측을 용이하게 하고, 후에 Feed Back 됨으로써 정확한 건설 프로젝트 타당성 분석을 가능케 하고자 한다.

  • With the advance of internet and computer processing technique, users can easily access and use the multimedia contents involving the various pictures, videos and audios information. And users request more convenient and accurate multimedia services. In these environments, it is difficulties to integrate and manage metadata standards because there are various standards in multimedia applications according to types of services and data formats individually. In this paper, we design and implement the multimedia metadata management system for integrating from heterogeneous sources. In our system, we managed heterogeneous metadata by integrating to unified schema using mapping table. Through proposed system, users can search multimedia data easily without considering variety of application services.

  • One of the most difficult tasks in pavement management information systems is establishing the links between performance measures of a structure and the design and construction inputs. In-situ pavement performance can be considered a response variable to many project input variables, such as design, construction, and traffic loading effects. If we are to fully understand the component of pavement performance and specify the inputs through design and construction specifications to achieve that performance we must develop quantitative relationship between input and response variables through a scientific, fully integrated Pavement Performance Analysis System (PPAS). Hence, the objective of this study is to design a database model required for developing an effective database template that will allow analysis of pavement performance measures based on design and construction information linked by location. In order to select the most appropriate database model, a conceptual database model (Entity Relationship Model) and dimensional model, which is believed to be the most effective modeling technique for data warehouse project, are designed and compared. It is believed that other state highway agencies could adopt the proposed design strategy for implementing a PPAS at the discretion of the state highway agencies.

  • 최근 기후변화로 인해 전 세계적인 지구온난화 피해가 심각해지면서 주요원인인 온실가스에 대한 배출 규제가 확대되고 있다. 그 중 온실가스 배출량의 약 25%를 차지하는 건물분야에 대해 정부에서는 2020년까지 BAU 대비 26.9%까지 감축하겠다는 목표를 발표하였다. 이를 달성하기 위해 건물부문의 에너지 수요를 원천적으로 저감하는 녹색건축물 활성화 방안을 추진하고 있다. 하지만 녹색건축물 활성화의 상세 이행계획 수립 및 관리, 그리고 시행에 따른 효과를 분석하기 위해서는 건물 에너지 사용량에 대한 데이터 및 관련 통계 자료가 필수적이다. 이를 위해 정부는 전국 680만동의 건물에서 사용되는 에너지 정보를 통합 관리할 수 있는 국가 건물에너지 통합관리시스템을 구축하였다. 하지만 현재 구축된 국가 건물에너지 통합관리시스템의 Database는 건축물대장 정보와 공급기관의 에너지정보를 매칭해서 사용하기 때문에 수동으로 작업이 이루어지고 있으며, 이로 인해 많은 문제들이 발생한다. 따라서 Database의 신뢰성을 확보하기 위해서는 지속적인 고도화 작업이 이루어져야 한다. 본 과제는 현재 가동 중인 국가 건물에너지 통합관리시스템의 Database를 분석하여, 시스템의 한계 및 개선방안 도출하고, 이를 통해 데이터의 신뢰성 확보 및 활용성을 증대 시키고자 하였다. 구축된 Database 분석 결과 건축물 정보와 에너지정보가 매칭된 유효데이터는 평균 85.6%이고, 미매칭된 데이터는 평균 14.4%로 나타났다. 미매칭된 데이터는 다시 건물 특성에 따른 미매칭 유형을 분석하였으며, 그 결과 건축물 정보가 없는 경우가 전체의 58.2%에 달했다. 따라서 향후 신규 구축 data의 매칭 작업 용이성 및 현재 Database에 대한 정확성 확보하기 위해서는 건축물 정보와 에너지정보 간의 주소 표준화 및 속성정보 체계를 마련할 필요가 있다. 또한 비도시지역 및 영세한 주거지역에서 사용비중이 높은 석유류 에너지원 및 향후 발전 가능성 및 활용 가능성이 높은 신재생 에너지와 같이 다른 에너지원에 대한 정보를 포함시킬 수 있도록 시스템 구축이 필요할 것으로 사료된다.

  • The objective of this research was to develop a relational database management system(RDBMS) to collect, manage and analyze data on agricultural non-point source(NPS) pollution. The system consists of the relational database for agricultural NPS data and data process modules. The data process modules were composed of four sub-modules for data input, management, analysis, and output. The data collected from the watershed of the upper Cheongmi stream and Geunsam-Ri were used in this study. The database was constructed using Apache Derby with meteorological, hydrological, water quality, and soil characteristics. Agricultural NPS-Data Management System(ANPS-DMS) was developed using Oracle Java. The system developed in this study can deal with a variety of agricultural NPS data and is expected to provide an appropriate data management tool for agricultural NPS studies.

  • As construction projects become larger, higher and more complex, efficient use of information is increasingly more important. As a result, there is a growing demand to apply BIM data obtained in the design stage to the construction stage. In this study, we propose a BIM-based construction schedule management system in order to promote introduction and application of BIM in the construction stage. Specifically, we provided how to build BIM database to be used for construction schedule management, and proposed how to obtain progress information and enter information based on analysis of progress schedule. We also provided a system of classifying construction works for more systematic use of BIM database, a process of using BIM database in construction projects, and a step-by-step guideline on how to establish the system. The proposed construction schedule management system provides information on particular construction schedule, as well as information and progress chart on delayed parts of the work so that a change in schedule can be managed. Additionally, by linking system database with the BIM model, construction progress can be checked in 3D simulation and a delay in construction schedule can be managed. As a result, using BIM at construction sites contributes to improving project productivity.
