In the case of the fire to the exterior of the building through openings, the openings of the adjacent building are exposed to the risk of combustion expanding and factors that affect the combustion in the radiant heat and direct flame. Recent five years, fire of the adjacent building indicated that incidence of the 5,134(2.27%) among total 225,934 cases occurred The damage scale of fire expanded was lower than in a single building but casualties(5.46%) and property(25.0%) damage were higher. Therefore, this study provides to analyze the operating status for fire protection equipment of fire-preventing area in the Seoul and to apply measures to improve fire protection equipment according to narrow the distance between the building openings studied.

We simulated a forest fire which was occurred in Yangyang area on 2005 and compared a results between two different weather conditions(real weather condition and mean weather condition since 1968) using FARSITE, which is a forest fire spread simulator for preventing and predicting fire in USDA. And, we researched a problem in the transition for introducing, so we serve the basic method for prevention and attacking fire. In the result, severe weather condition on 2005 effected a forest fire behavior. The rate of spread under real weather condition was about 4 times faster than mean weather condition. Damaged area was about 10 time than mean weather condition. Therefore, Climate change will make a more sever fire season. As we will encounter to need for accurate prediction in near future, it will be necessary to predict a forest fire linked with future wether and fuel condition.

Recently, the buildings have gradually become higher, more massive and more complex with high growth of economy and varieties of the patterns of people's living. Therefore we study a performance and Improving Methods of the fire compartment as a measure to minimize the damage of the people and property from the fire. Currently, under the economic crisis situation, we do not consider about prevention of disaster safety enough; safety investment evasion, safety carelessness, and management relaxation etc. Also in the aspect of regulation system, industrial technology and plan engineering, Korean techniques of preventing fire disasters are far behind of other advanced nations. At this point, we are in need of improving about it. When considering like this situation, we need more studies on the practical improvement in order to assure fire prevention for buildings. The fire compartment prevent from magnifying the fire to the wide area by compartment into specific area. From this, it is possible to minimize fire damage and property and secure emergency exit for life safety. This fire compartment has primary function to extinguish fire easily, and the openings and penetrations are important passage which makes the smoke and fire go away from the fire area to the contiguous space. This study suggests improving methods of domestic fire compartment efficiency standard through comparative analysis of overseas advanced provision and domestic provision about base element of the building fire prevention.

The offshore installations and ships are the structures most likely to be exposed to hazards such as hydrocarbon fire and/or explosion. Developing proactive measures to prevent the escalation of such events thus requires detailed knowledge of the related phenomena and their consequences. $CO_2$ extinguishing systems are extensively used for fire accidents of on-and offshore installations because of outstanding performance and low cost. There is, however, the risk of carbon dioxide system which enumerates many of the fatalities by suffocation associated with industrial fire protection requirements. Therefore, the aim of this study is to perform the prediction of fire suppression characteristics of the carbon dioxide system in realistic enclosed compartment area of ships and propose $CO_2$ extinguish fire fighting system for preventing suffocation accidents during fire fighting. According to CFD calculations, it can be observed and assessed that various fire profiles with $CO_2$ and $O_2$ mole fraction in the target enclosed compartment area are applicable within the proposed system. Additionally, the design of fire safety system of ships and offshore installations can utilize ventilation system and/or layout arrangement through the proposed system.

We studied a basic concept and application about FARSITE, which is a forest fire spread simulator for preventing and predicting fire in United States Department of Agriculture(USDA). And, we researched a problem in the transition for introducing, so we serve the basic method for prevention and attacking fire. For this transition, we compared the behavior of the 2005 Yangyang forest fire with the result of a simulation. The spread direction is similar to real data. But, while mean spread of rate was 0.65km/hr on real data, it was 0.3km/hr on simulation. As Damaged area is 1,387ha on real, it was 5,368ha on simulation. Therefore, it is necessary to establish a fuel concept for more accurate simulation.

산업단지내 위험물 저장탱크 기초의 결함으로 인한 위험물질의 유출사고는 인근 지역의 대형 인명사고 및 대형화재를 일으킬 수 있으므로 기초의 설계 및 시공단계에서 세심한 주의를 기울여야 한다. 본 연구에서는 기존 위험물탱크 단지가 건설된 대표지반을 선정하여 3차원 모델링에 의한 유한요소 수치해석을 수행하였으며, 위험물 저장탱크 기초의 안정성 평가를 위하여, 대표적인 탱크 기초 유형을 4종류로 분류하고 각 유형에 대한 해석을 수행하였다. 결과적으로, 탱크기초의 응력 및 침하량 크기와 분포 특성은 링월기초의 경우 옆판 직하부분이 탱크 중심부에 비해 40배 이상의 응력이 집중되는 경향을 보였으며, 침하영향범위는 수평방향으로 탱크 반경만큼, 수직방향으로 탱크 직경만큼으로 나타났다. 본 분석결과를 활용하여 각 기초 유형별로 위험물 저장탱크의 설계 및 품질관리 가이드라인을 제시하였다.

It can be meaningful that this study attempted to analyze the use cases and forms based on the literature on the painting walls of the J oseon Dynasty, and attempted basic research to prevent disaster damage using traditional elements. This study summarizes the use of the Hwabangbyeok wall of J oseon Dynasty as follows. First, Hwabangbyeok wall was used from the early J oseon Dynasty and was adopted by palaces and other major state facilities to cope with fire and theft. Second, the Hwabangbyeok Wall was also referred to as the wall below the lower part of the wall, and was constructed with the purpose of preventing disasters from outside. Third, in an analysis of the Daeseongjeon shrine of Hyanggyo, many construction cases were identified mainly in the Gyeonggi area, which is assumed to be based on production and construction conditions along with local climatic factors. Fourth, it can be said that the Hwabangbyeok wall was basically adopted to prevent comprehensive disaster risk reduction in case of external intrusion and fire.

최근 도시화 및 인구의 밀집화는 전 세계적인 기후변화의 영향과 더불어 재난의 대형화 및 복합화를 유발하고 있다. 그러나 국내의 경우, 재난발생에 대하여 예방, 구조, 복구에 중점을 두고 있으며, 재난 시 생명유지에 절대적으로 필요한 재난의료는 외면되고 있는 실정이다. 따라서, 본 연구에서는 침수피해가 빈번하며, 지하주택이 밀집되어 피해가능성이 크다고 판단되는 서울시를 대상으로, 침수이력지역의 지하주택을 응급환자 발생지로 가정하고 이송거리 및 이송시간을 분석하였다. 본 연구는 응급의료시설과 재난발생지로의 접근성과, 구급대로부터 재난발생지로의 접근성을 함께 고려하여 응급의료서비스 개선의 기초자료로써 의의가 있다고 판단된다.

피난방화문이란 기존에 성능을 인정받은 방화문의 전면에 축광도료를 바르고 손잡이 부근에는 시온도료를 발라 제작한 방화문으로 기존에 방화설비로만 사용되었던 방화문에 피난 및 안전 기능을 추가, 방화문 자체가 피난설비로서의 기능을 겸용하는 설비이다. 피난안전방화문의 휘도는 기존의 유도표지 휘도(60분후 7mcd)이상의 성능으로 한국소방산업기술원의 휘도시험을 통과한 설비로, 화재 시 가시성의 면적이 피난구유도등에 비해 크며 연기의 하강에도 방화문 아랫부분의 방광상태가 관찰되어 피난자들의 피난유효 시간을 연장시켜 줄 것으로 사료된다. 손잡이 부근에 발라져 있는 시온도료는 일정온도에 도달하면($70^{\circ}C$) 색상이 변화 위험경고가 방화문 바탕에 나타나게 되어 화재 시 피난자들이 방화문 손잡이에 입을 수 있는 1차 재해를 예방할 수 있으며, 화재공간에 진입을 하여야 하는 소방관들에게는 역화 가능성을 사전에 인지 안전 사고를 예방하는데 도움을 줄 것으로 판단된다.
