  • The importance of LCC analysis has been enlarged. Also, it would be necessary to computerize LCC analysis for accurate and logical analysis of LCC. In other papers, they showed LCC analysis model but the study of database development which could be applied in LCC analysis have been undeveloped. As a result, the final goal of this study is to develope LCC database. And this progress is devided 4 steps as design, construction, maintenance and disposal and derived the detailed cost item in the progresses. Futhermore, it would be possible to develope cost DB, fluent DB, general DB, building section DB, material DB and to propose database which would be applied in accurate and logical analysis of LCC.

  • 국내 건설공사의 기획 설계 시공 유지관리 전 단계에서 발생하는 방대한 정보를 제공 중인 건설CALS시스템은 국토해양부 뿐만 아니라 건설사 및 1,400여 곳 이상의 건설현장에서 사용 중인 시스템이다. 그러나 건설CALS를 구성하고 있는 단위 시스템들의 개발 시기 및 주체가 달라 통합 기능개선 운영 단계에서 DB의 논리적 구조가 복잡하게 변경되어 데이터 누락, 처리속도 저하 등의 문제가 발생하고 있다. 이에 본 논문에서는 건설CALS를 구성하고 있는 4개 시스템의 DB를 분석하여 개선이 필요한 항목을 도출하고 취약한 부분의 개선방안을 제시하였다. 제시된 방안은 DB시스템을 운영하는데 있어 가장 기본적인 방법으로써 쿼리문의 처리속도 및 DB장애 발생 시 복구능력 향상 등을 통해 시스템의 안정적이고 효율적인 운영이 가능하다.

  • People use various information for searching POI in the navigation system such as name, category, address, phone number. Most of users use name and category to search their POT. They don't know exact name in POI DB provided by Maker. They use abbreviated or generalized name as key word for searching POI. Because of these reasons, the hit ratio has been very low. In this paper, We suggest a extra DB_construction system for raising the hit ratio. It generates allomorphes DB link to the POI name in original DB. We classified the POI names in original DB into seven types of allomorph by analyzing the gathered patterns from the POI DB which has over 650,000 entries. For auto_generating the allomorphes, we made 577 rules based on the classified types. And we generated the allomorphes manually for the entries which are difficult to make the rule and has low frequency The generated allomorphes account for 35.8% of all original DB. The hit ratio is 89% under suggested system.

  • For a successful construction project not only construction engineering and project management technology but also economic evaluation technique is required. Design and construction technologies are necessary to receive a project order. However, construction management technology which can be apply from the project initial phase to the project operation and management phase is required to create a benefit from the project. Construction management technology is one of the effective factors for project success. Economical and efficient cost management from the planning phase influences the project success. This study investigated cost flow and cost factors of domestic Sewage Treatment Plant project for systematic analysis of cost items following the entire project phase. Particularly, data modeling based on domestic Sewage Treatment Equipment maintenance cost DB was performed, and maintenance cost estimation trend line is suggested using Monte carlo Simulation Method to decrease uncertainty of actual results DB and for feasibility study.

  • Recent construction projects have been complex, larger and therefore BIM-based simulation has become more important. Through BIM simulation prior to the project improves the reliability and safety. Temporary plan is very important and all projects are an important foundation. However, a temporary plan to apply the BIM simulations are not going well. The reason for the building of a library well enough and the DB is not made. Therefore, a temporary plan of the library database is the correct formulation needed.

  • The schedule management in construction project have been performed independently by two method, WBS base management and CBS based management, However, the integrated management model is needed according to efficiency of construction project management and introduction of new EVMS system of KOREA government. For this purpose, interworking database system is designed through efficient modeling of WBS based management data and CBS based management data and relation establishment between entities in this paper. WBS based management DB consists of 4 entities and CBS based management DB consists of 3 entity and one of the 4 WBS DB entities is used to play interworking role between WBS and CBS, Also, attributes of all entities are well defined so that data consistency, integrity and newest are guaranteed. The designed interworking database model was realized using Nex-Pert Pro and the efficiency of data interworking was proved.

  • According to computer-based life style and computer networking system is generalized, the construction of information system based on the construction of database is one of the major jobs in the design field. The construction of standard database system is one of the major factors to build the information infra and develop design field as knowledge-base industry. However, the construction of user-based dassification of database is prior to that of standard design database system. This study presents the possibility of the construction of user-friendly and standard database system by studying the dassification system of database.

  • The Ministry of Land, Transport and Maritime Affairs(MLTM) project for the DB construction of national geotechnical information was automatically computerized the geotechnical investigation results on the construction site in 2007. So 'the rule for computerizing of geotechnical investigation results and its application' were promoted the establishment and applicable project. It was promoted in earnest that all organization and affiliation of MLTM, local governments included the project because of stabilization of the law from 2008. We have analyzed a application-ratio of geotechnical information about users of geotechnical information system and distribution data and established a plan of applying enhancement for the DB construction and DB utilization in 2008. In this paper, we propose the result for application-ratio analysis and application plan through the application-case study of national geotechnical information DB. In the application-ratio analysis, the analysis in the field shows the most high as 39% in construction planning and preliminary investigation, the analysis in the effect of capabilities shows the most high as 25% in the increased efficiency of business. Also the analysis in the field of application shows the most high as 95% a application-ratio of geotechnical information in architecture and civil.

  • Looking at the changes in the earthquake of 33 years of South Korea, earthquake in the magnitude of 3.0 or stronger have been conducted about nine times a year on average, and the epicenter of the earthquake is moving towards the inland from the coast. As the possibility of earthquakes increase, it is time to require utilization of underground space integrated information for earthquake disaster prevention. But, now the data related to the characterization of the ground and geology in the areas weak against earthquakes is insufficient, so we need to collect new geology and the ground survey data on nationwide scale and have to establish earthquake disaster prevention plans through the joint use of the existing underground space information. In this study, we determined the scope of construction of underground space DB information that is needed for earthquake disaster prevention, presented the construction plan of DB static and dynamic information of underground space. It also suggested the utilization of underground space scheme information for built earthquake disaster prevention. The underground space information for earthquake disaster prevention that was built through determining the scope and constructing, planning the utilization of underground space information is supposed to used as DB of the integrated management system of underground space and steep slopes information for steep slopes and earthquake prevention by Emergency Management Agency.
