The purposes of fire investigation are to identify and analyze the causes of fire and, using the results in promoting fire fighting policies, ultimately to prevent fires caused by similar causes and to protect people's life and properties from fire. However, although the patterns of fire are getting more diverse and complicated with the rapid development of industry, complicated with the rapid development of industry, fire fighting organizations are continuing traditional superficial fire investigation without operating a fire investigation department for the reason of insufficient manpower, equipment and budget, losing public confidence. Thus, the present study purposed to propose plans to improve the technicality of fire investigation and win public confidence in fire investigation. First, the technicality of fire investigation should be improved by operating a department and personnel exclusively for fire investigation. Second, fire investigation should be more scientific and precise using high tech fire investigation equipment. Lastly, responsible fire fighting administration should be realized through statistical analysis of the causes of fire and computerization. The results of this study are expected to contribute to the safety and security of our society.

필댐에서의 침투수량 관리는 댐 운영 및 유지관리에 있어서 매우 중요한 사항으로 댐체 내 침투수에 따른 안정성 검토 등 판단 근거로 활용할 수 있다. 본 장에서는 침투수량 관리 개선 조치를 완료한 댐시설을 대상으로 최근 정밀안전진단 시 개선 조치 적정 여부 판단을 위한 침투수량의 물리적 변화 정도를 분석하여 과거 자료와 비교하고 그 결과를 토대로 기초지반 보강공사에 따른 침투수 집수기능 회복 효과를 판단한 결과를 정리하였다.

Interior permanent magnet synchronous motor [IPMSM] which has high power density is applied to motor for Hybrid electric vehicle[HEV], Electric vehicle[EV], Fuel cell electric vehicle[FCEV] and electric home appliances. In order to improve efficiency performance of IPMSM, this paper presented a study by making a hole around air barrier. Because concentrated rib stress is distributed by suitable hole, the hole can reduce rib thickness of IPM rotor. And it can help decrease PM[Permanent Magnet] leakage flux. Saliency ratio(L<SUB>q</SUB>/L<SUB>d</SUB>) is also increased by magnetic circuit change. For this study, structure analysis of rotor is performed by Ansys program.

Load test is performed to obtain the data to evaluate load carrying capacity and check static & dynamic characteristics of a structure by estimating the real behavior of bridge due to loading the load. The subject facility in this paper is a bridge located on the spiilway of dam and traffic is relatively less than most brige. Considering the age and operation rules of a dam, however, load test and structure programming analysis were performed to check current conditions for structure under in-depth inspection and the results of that analysis are shown.
