The purpose of this study is to analyze the reference data of the National R&D Report database built by the Korea Institute of Science and Technology Information(KISTI) to derive problems and to find complementary points for the construction technical items in the system. To this end, we investigated the descriptions of references in the National R&D Report constructed in the KISTI DB and analyzed the construction process, guidelines, types, items, etc. Based on this, the appropriateness and accuracy of the classification results of the reference types constructed with the DB were checked. As a result, the problems of the items built into the system and corrections to the construction guidelines were derived. Through this, database construction can proceed efficiently and data quality is expected to improve. In addition, a follow-up study was proposed on the convergence service plan that can be provided in the future through standardization of technical regulations.

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.

National Geotechnical Information Database Project based on GIS has begun as public works and continued until now, the whole of country has been target on since the 2003. Today, the 60,581 number of geotechnical data(counted by bering number) have been constructed as GIS-DB and they are being serviced at the National Geotechnical Information Integration Management System(NGIIMS)(http://www.geoinfo.or.kr). In this study, we considered operation status of NGIIMS, GIS-DB distribution of Geotechnical Information and utilization in order to investgate applicability of National Geotechnical Information Database. The results appeared that Geotechnical Information DB was along road-center, and in the case of complex, was only to some area. But after the 2007 when the law of computerization responsibility would be institutionalized, the more geotechnical data will be constructed and be able to use at a construction site.

The purpose of this study was to investigate housing DB construction for elderly people. Document research and content analysis methods were used in this study. The major results of this study are as follows. The number of elderly household is increasing very rapidly. In particular, they consist of a single person or a couple. These households prefer to live and age in a detached house. However, the social welfare system does not satisfy their needs. Therefore a systematic social support or welfare system is required to reflect their needs. For example, related works of housing welfare need to be prepared so that their data base system correctly reflects the socio-demographic characteristics and living conditions of the elderly.

The purpose of this study was to investigate the way of housing DB construction about the elderly people. Documentary research and content analysis methods were used in this study. The major results of this study are as follows. The number of elderly household is increasing very rapidly. Especially they consist of single or coupled family. They want to live in detached house and aging in place. But social welfare system is not enough to satisfy their needs. So, it is need that systematic social support or welfare system to reflect their needs. For example, related works of housing welfare for them are prepared that their data base system as socio-demographic characteristics and living conditions.

Numerous reports show that alternative project delivery systems (PDSs) such as design-build (DB), construction management at risk (CMR), and design-build-maintain (DBM) are increasingly used in many countries. This study compared characteristics of each PDS (design-bid-build (DBB), DB, CMR, or DBM) by analyzing quantitative data from 9 research articles. In order to compare characteristics between DBB and alternative PDSs, the study is based on principal 3 factors - Time, Cost, and Quality. DB shows the best performance in the time part and also the cost performance depending on facility type and project size. The performance of quality has minor difference among different PDSs. These results support the fact that using an appropriate PDS by the characteristic of a project makes high value of efficiency and productivity.

The repetitive occurrence of similar accident is one of the biggest feature in construction disasters. Similar accident cases provide direct information for finding risk of scheduled activities and planning safety countermeasure. Many systems are developed to retrieve and use past accident cases by researchers. However, these researches have some limitations for performing too much retrieval to obtain results considering construction site conditions or not reflecting characteristics of safety planning steps or both. To overcome these limitations, this study proposes accident case retrieval system that can search similar accident cases. It also helps safety planning using information retrieval and building information modeling. The retrieval system extracts BIM objects and composes a query set combining BIM objects with site information DB. With past accident cases DB compares a query set, it seeks the most similar case. And results are provided to safety managers. Based on results of this study, safety managers can reduce excessive query generation. Furthermore, they can be easy to recognize risk of a construction site by obtaining coordinations of objects where similar accidents occurred.

Information of construction material is served through internet to user but it is poor to use information of construction material because of lack of information which is accumulated and insufficience of standardization. So informationization of civil materials are closely connected with works and then it is promoted to be used through works like design, construction etc. Informationization for management of information of construction material which reflects questionnaires about opinion of workers presents promotion by stage considering first, continuous renewal of information of construction material and increase in quantity, second classification system and standardization of terms in order to share and connect information of construction material third, developing inquiry method of material information needed in construction stage fourth, connecting material information DB and application through design and construction.
