Because of the development of advanced construction technology, the inner environments of building become more and more complicated, which may result in many problems. The administer may forget where they put up the certain picture, and search for it all over the building, or they underestimate the number of the visitors, and find the situation is out of control, while the pedestrian may get lost, and after making their efforts, they found they turned back to the origin point again. So it is very necessary to establish an indoor spatial database. On one hand, it is able to assist administrator to manage the property and human flow inside the building, on the other hand it could help the pedestrian find the way easily especially when they are not familiar with the building or there is an emergency. This paper focused on how to create the indoor spatial database including both static database and moving objects database. The static database is built on the basis of 3D building models, and the moving objects database gets information from many kinds of cameras and sensors installed in the building. And at the same time the paper discussed the practical use of indoor spatial database mainly in three aspects including consistency management, building restructure, and pedestrian navigation.

Building materials have a great impact on the health of a building's occupants. Thus, it is imperative that their health-related properties be taken into during the course of construction project. Unfortunately, no current database system exists that can provide information on the health performance of building materials at each stage of construction project management, from planning and design to building and maintenance. therefore, an inordinate amount of time and effort is required to choose the right health-friendly materials(DBHM). To solve this problem, this study aims at building a database management system for health-friendly building materials. It analyzes the health-related properties and performance of various materials, and proposes a database structure and operation algorithm. The system proposed in this study is expected to contribute to the objective evaluation of health-friendly building materials through the accumulation of relevant data.

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.

Geographic Information has been used widely for landuse and management, city plan, and environment and disaster management, etc., But geographic information has been built for individual cases using various methods. Therefore, the discordancy in data, double investment, confusion of use and difficulty of decision supporting system have been occurred. In order to solve these problems, national government is need to framework database. This framework database was enacted for building and use of National Geographic Information System and focused on basic plan of the second national geographic information system. Also, the framework database was selected of eight fields by NGIS laws and 19 detailed items through meeting of framework committee since 2002. In this research, The 19 detailed items( road, railroad, coastline, surveying control point etc.,) of framework database consider a Priority order, In the result of this research, the framework database is obtain to a priority order for building and the national government will carry effectively out a budget for the framework database building. Each of 19 detailed items is grouping into using the priority order of the framework database by AHP analysis method and verified items by decision tree analysis method. The one of the highest priority order items is a road, which is important for building, continuous renovation, and maintain management for use.

This study is aimed at utilizing LCA processor with BIM LOD, eliciting the problems of the existing environmental assessment by constructing the database for environmental values of green buildings. For these objects, environmental load database of BIM construction material and evaluation process are presented, after matching BIM family based environmental load database which is available during evaluation stage, input-output tables and Korea LCI database to standard item code of public procurement service. It is a important factor in environmental assessment of building to develop database unit of standard item code for BIM and construction material. Thus, the results of this study are expected to provide basic data for improving effectiveness of construction through BIM based environmental load evaluation database. Furthermore, the provided environmental load database unit for construction material is considered to be available as basic information for BIM study by suggesting a processor connecting BIM with LCA and along with this, continuous examination on the connection process is needed.

건축물은 건축자재의 선택과 사용에 따라서 전혀 다른 이미지로 보여 질 수 있다. 건축물을 설계하는 과정에서 건축물을 검증하거나 가시화된 이미지를 얻어내기 위해서 여러 가지 시뮬레이션 프로그램들을 사용하고 있다. 하지만 대부분의 시뮬레이션 프로그램은 국외에서 생산되는 건축자재정보에 대한 데이터들로 이루어져 있기 때문에 국내의 환경에 맞게 적용하는데는 많은 어려움이 따른다. 본 논문에서는 국내에서 생산되고 사용되어지는 많은 건축자재를 바탕으로 데이터를 수집하고, 건축자재가 가진 광학적 특성을 측정하여 데이터베이스 구축을 위한 방안을 제시하였다. 최종적으로 RADIANCE 엔진을 이용하여 개발된 인터넷 웹기반 가시화 시스템에 구축된 국내 건축자재의 데이터베이스를 적용하였다.

From this year, KIGAM, one of Korean government-supported research institutes, has started new national program for digital geologic/natural resources infrastructure building. The goal of this program is to prepare digitally oriented infrastructure for practical digital database building, management, and public services of numerous types of paper maps related to geo-scientific resources or geologic thematic map sets: hydro-geologic map, applied geologic map, geo-chemical map, airborne radiometric/magnetic map, coal geologic map and off-shelf bathymetry map and so forth. As for digital infrastructure, several research issues in this topic are composed of: ISP (Information Strategy Planning), geo-framework modeling of each map set, pilot database building, cyber geo-mineral directory service system, and web based geologic information retrieval system upgrade which services Korean digital geologic maps scaled 1:50K. In this study, UML (Unified Modeling Language)-based data modeling of geo-data sets by and in KIGAM, among them, is mainly discussed, and its results are also presented in the viewpoint of digital geo-modeling ISP. It is expected this model is further progressed with the purpose of being a guidance or framework modeling for geologic thematic mapping and practical database building, as well as other types of national thematic map database building.

In this study, we analyzed applicability of object database, designed the concept model based on object-oriented idea for measurement data management, and applied the design model to object database. The concept model composes three sub models Infrastructure managing information model, Infrastructure measurement data model, and Measurement unit model. The process to expand measurement data of new type was executed easily without changing database schema in object database. The process to expand measurement data of new type was executed easily without changing database schema in object database. Therefore, applicability of new technology to infrastructures for building a safety management network of road bridges could be increased with object database system.
