GIS was introduced to spatial information of complex and various facility systematically and scientifically. And, recently, new trend has been spread by Mobile GIS owing to its fast development of information and communication technology However, these Mobile GIS techniques were introduced in maintenances of various facilities. Due to its mismanagement, the use became insufficient in facilities causing database creation to require realism and mobility. Therefore, in this research, to road facility of various facilities, it deduced improving the work process by using a Mobile GIS to analyze work process of the road facility database creation. And, through an experiment, by comparing and analyzing road facilities database creation process by existing method and improving method, could improvement of road facility database creation using a Mobile GIS.

A lot of nursing facility expansions are needed by rapidly growing elder population and operating long-term nursing act for the elderly from July, 2008. To supply facilities in a short period, government is considering a method which is converting usage of existed building to nursing facility. Therefore, we took actual state analysis by interviewing manager, surveying actual measurement and using draft among the converted facilities. To improve and encourage those living environments of nursing facilities, we need to establish design standard of adaptable facility.

North Korean market created by reunification of the Korean Peninsula is expected to serve as a new growth engine to the already-developed construction industry of South Korea. Improvement on deteriorated construction facility of North Korea is a project in urgent need at the initial stage of reunification. Prior to market entry of the Korean peninsula under these circumstances, economic feasibility analysis on construction technology application must be preceded by considering reunification period. Therefore, this study conducts an economic feasibility analysis on construction facility improvement project of North Korea considering application period of technology developed by South Korea. Results of this study are expected to be utilized in future reunification process as the basis for establishing relevant guidelines for construction facility improvement project of North Korea.

Despite the rise of importance of Facility Management(FM), relatively little attention was paid to evaluate FM efficiency and drive for greater FM efficiency. The purpose of the present paper is to offer a quantitative analysis of 14 Key Success Factors(KSF) and 22 detailed maintenance practices in order to develop FM evaluation system. In addition, from survey with Owner/Property Manager group and Facility Manager group, the present paper measures both importance of detailed maintenance practices and performance satisfaction. It is expected that by using the result of this survey, this paper helps increase efficiency in FM. Moreover, It is expected that this paper will be used as base line data in developing FM practice evaluation system.

In this paper, RETScreen program model has been investigated to predict the economic analysis for greenhouse and livestock facility. Load calculation result was 35.2[kW] of greenhouse and the calculation result of livestock facility was 35.5[kW]. Also, a case study of the RETScreen program indicated that the equity payback is 6.9 years for a greenhouse facility and the equity payback is 9.5 years for a livestock facility.

Cryogenic pump test facility (CPTF) is designed and developed in KARI. Hydraulic and cavitation performance of pump and inducer in cryogenic environment can be measured. Working fluid is liquid nitrogen and operating temperature is $-197^{\circ}C$. Run tank, catch tank of liquid nitrogen and their pressurizing tank has been built and remote tank pressure control system are installed. Maximum power of driving motor is 320 kW and its maximum speed is 32000rpm. Cryogenic fluids and lubricating systems are effectively separated that long test times are acquired. Therefore hydraulic and cavitation performance can be measured accurately and effectively. Pre-cooling test of the facility was successfully accomplished. This facility will contribute greatly to the development of turbopump for KSLV.

This paper describes basic plans for the development of a radioactive waste disposal facility with the introduction of Nuclear Power Plants (NPPs) for Kenya. The specific objective of this study was to estimate the total projected waste volumes of low- and intermediate-level radioactive waste (LILW) expected to be generated from the Kenyan nuclear power programme. The facility is expected to accommodate LILW to be generated from operation and decommissioning of nuclear power plants for a period of 50 years. An on-site storage capacity of 700 $m^3$ at nuclear power plant sites and a final disposal repository facility of more than 7,000 $m^3$ capacity were derived by considering Korean nuclear power programme radioactive waste generation data, including Kori, Hanbit, and APR 1400 nuclear reactor data. The repository program is best suited to be introduced roughly 10 years after reactor operation. This study is important as an initial implementation of a national LILW disposal program for Kenya and other newcomer countries interested in nuclear power technology.

The railroad station building is a public facility that many people use. The disabled persons cannot move as freely as the ordinary persons do, so the facility shall be considered on this matter. We reviewed on the features of the retarded, visually handicapped and mentally retarded persons upon moving, and calculated the minimum space required in their move, access and use of the reachable space, and we also analyzed the design factors so that the prior guidance can be considered for the visually handicapped such as installation of guidance facility, change of finishing material and Braille points block handrail to avoid obstacles for the use of senses of touch, hearing and remained eyesight of the visually handicapped. In addition, we also analyzed the requests of general design totally to analyze and arrange the design factors with the thought that the facility for the handicapped shall be useful for the ordinary people as well as the handicapped.

A cryogenic test facility has been developed to perform inducer and pump tests using liquid nitrogen. Performance tests of a turbopump in the maximum 50ton-thrust class can be performed with cryogenic fluid in the facility which operates at a temperature around -196oC with the rotational speed up to 30,000rpm To verify the reliability of the cryogenic pump test facility, hydraulic performance tests of an inducer were accomplished, and their results were compared with the result from a water test. The results confirm the reliability of the cryogenic test facility, and it is expected to contribute for on-going development of a turbopump for liquid rocket engines.

In this paper, for deriving core function requirements of facility maintenance using BIM(Building Information Modeling) customized surveys were conducted with 30 facility managers during 6 momths from July 2014. As a result, 19 core function requirements for efficient facility maintenance are drawn. The core of Building facility management function is that opinions of facilities maintenance managers should be fully reflected than that of BIM experts. In the future, the development of maintenance programs based on BIM should be made fully by reflecting the opinions of building facility managers on the basis of this questionnaire survey results.
