  • 대용량 기기의 효율적인 전력 공급을 위해 부스닥트의 수요가 급증하고 있으며, 특히 컴팩트형 부스닥트는 케이블에 비해 무게와 부피가 가볍고 전력 효율도 25% 이상 우수하며, 기술의 핵심은 에폭시분체도료의 절연 특성 향상과 제작공정의 최적화와 안정화이다. 따라서 본 연구에서는 유동침적방식(Fluidized Bed Process)에 대한 최적화와 에폭시 분체도료의 절연설계 및 열화특성에 대해 실험 검토 하였다. 또한 전기화재의 주된 원인인 아크방전특성과 절연파괴 특성에 대한 분석과 더불어 다양한 상용제품들의 특성을 비교하였다.

  • As use of tunnels and subways increase there also are accidents proportionate to it. Daegu Subway Station fire, Hongjimoon tunnel fire led people to be conscious of disaster protection and as a result, there is a trend to adopt standards for fire protection. Accordingly, this thesis is focused on investigating various fire and water protection related issues for subaqueous tunnel under Ran river. The thesis developed evacuation and disaster prevention plan as fire level increases and have identified the suitability of disaster prevention through evacuation and fire simulation, countermeasure of a water leakage during construction and operation considering the subaqueous tunnel. And we selected EPB shield TBM equipment considering the ground condition and effect of boring hole, and accomplished reasonable water protection design through setting goals using event-tree method, as well as examining model test of boring hole and flooding in heavy rain. Also included structured total system consist of water leakage sensing system, water protection gate, pumping system and fire protection system to respond systematically in emergency.

  • The automatic fire detection system is an important facility installed with focusing on minimizing the damage from a fire. This paper presents in the followings as the methods to reduce the false alarm of the automatic fire detection system; first, to prepare for legal standard so that revised legal standard can be applied to the fire fighting property prior to revision; second, to introduce the performance based fire detection protection design in the law based fire protection design; third, to maintain the wiring of worn-out detector; forth, to introduce an evaluation system to the education for the fire warden; fifth, to extend the standard of MTBF(meantime between failure) of the detector; sixth, to extend of installing the analog type detector; seventh, to improve the structure of reset switch.

  • There are many institutes which manage the disaster protection resources in their system. The system of the institutes is not mutually compatible, because there is no standard framework of the classification and identification for the disaster management resources. NIMS of FEMA defines the classification and identification framework for the incident resources. All incidents management system of USA including IRIS and webEOC follows the standard resources framework. The aim of the classification and identification of the resources provides the resources list for the disaster and supports to find the resources information efficiently. In this study, we defined the classification and identification of the resources considering the compatibility with the international standard and the field requirements.

  • The resident's understanding of subway fire disaster broken out in Daegu city, February 2002, was analyzed using netizen's opinion on Internet Web Site. Based on the data of the resident's understanding, fluctuation curve for disaster prevention was modeled to assess quantitative consciousness. Our research will be useful to maintain continuous understanding for disaster protection.

  • 최근 국내의 대규모 건축물은 기존의 사양적인 피난안전계획은 미흡한 실정이다. 실질적인 방재대책 및 구체적인 피난안전계획에 관한 연구가 필요하다. 하지만 국내의 경우 성능설계 등이 현재 법제화가 이루어 졌으나 구체적인 방법론이 미비한 실정이다. 특히 재해약자의 피난특성을 고려한 피난안전계획은 이루어지지 않고 일반적인 피난성능만을 고려한 설계가 계획되고 있다. 따라서 재해약자 중 고령자를 중심으로 국외의 피난대책을 고찰하고, 이에 대한 한국의 개선방안을 도출하였다.

  • It is important to establish a strong system of agencies for protection against disasters. Also, the system of protection against disasters by the residents is necessary to be strengthen the system. We examined the roles of the protection agencies and the administrational institutions against disasters. The results are: 1) The mutual assistance agency relies on the administrational institution on a hardware surface., 2) On the software surface some systems of protection from disasters are under the control of the agencies, and some are under the control of the administrational institution., 3) The shelters are unable to meet the needs of people in any disaster. Thus, we should use of the existing institutions as evacuation areas., 4) The people working in the city in which they live tend to know the protocols of the disaster measures and to recognize the disaster maps well.
