  • This study is about determination of fire origin by using analysis of shadow that was recorded CCTV data at the fire scene. This analysis is based on straight and radiate nature of light. At fire experiment with about 1m flame, we conformed that 2-dimensional extension line is focused at the bottom of the fire. If the fire is burning at the same level with shadow, it indicate the point of origin exactly. In 3-dimensional analysis that connect extensional line between distinctive points the shadow and the objet, the line focused in the ${\emptyset}$ 50cm-circle. We estimate the reason of that is because of the character of combustion of gases. The line indicate not the point of origin but the flame that is over the point of origin. thus, you have to consider the line indicate the flame when you do 3-dimensional analysis.

  • Because recently(July 14, 2011) fire occurred in the engine room of a moving taxi under Namsan Tunnel 1, 51 vehicles' driver and more than 250 passengers in the road tunnel were urgently evacuated with abandoned vehicles. Vehicle fires in Namsan Tunnel that day, Sufferers struggled to escape quickly difficult to escape the two-way by abandoned vehicles on the road and to fear many casualties by using vehicle fuel and combustible interior and the driver who is ignorant of vehicle accident continuous entered in the road tunnel had accessibility the site of fire department was more difficult. In this study, It is to investigate structure and basic materials, such as fire extinguish equipment and facilities for damage prevention and to analyze the problems and to plan improvement method of fire extinguish equipment, facilities for damage prevention and transportation facilities(Large traffic signs, Breaker, etc.) on the Namsan Tunnel that in the long-term plan is prepared to strengthen for accessibility of the site of fire department in case of Vehicle's fire.

  • In this study, the height of the flame required to estimate the heat flow path and flame spread in pool fire has been applied by the empirical formula, but it is calculated without applying the pressure and temperature parameters of the fire room. Until now, the height of the flame applied to pool fire was $l_F=0.235Q^{2/5}-1.02D$ in the Heskestad empirical formula, but accurate temperature calculation was not possible due to the temperature and pressure which are not influenced by the flame height. Therefore, applying the temperature and pressure around it can calculate the exact flame height, which can be applied to fire investigation and fire dynamics. The structure of the flame is divided into a continuous flame, an intermittent flame, and a buoyancy flame, but it is assumed that the flame height is calculated from the visual aspect to the intermittent flame region, and the temperature of the buoyancy flame is very low. The effect of heat of vaporization on the height of flame was investigated. The results showed that flame height was different according to the pressure and temperature around the fire room.

  • Recently, the number of cases of fire spreading due to exterior materials of buildings is increasing. Due to the nature of modern architecture, which emphasizes the aesthetics of buildings, because buildings pursue a splendid appearance, they are inexpensive and have relatively good insulation performance, but an increasing number of buildings are adopting insulation materials that have poor fire safety performance. The risk of spread is also greatly increased. Since the exterior wall of a building is made of a variety of materials and structures, it is composed of a combination of several elements, including materials such as insulation and finishing materials. Therefore, it was determined that it was necessary to introduce a more systematic evaluation method for building exterior materials, and to improve the system reflecting this, away from the existing evaluation method that only checked the fire safety performance of finishing materials.

  • In this paper, as there are many cases of fires occurring due to the failure or inoperability of the thermostat of electronic products, the purpose is to test and analyze the risks and probabilities through fire cases and reproduction experiments, and suggest countermeasures. Among electronic products, water purifiers are composed of a refrigerant system with a compressor to make cold water, a heating device to make hot water, and an electric device used as an energy source. Due to the nature of the water purifier manufacturing, these devices are subject to a lot of moisture and dust. etc. exist in large quantities and use electrical energy, so there is a possibility of fire due to short circuit in the wire, electrical abnormal overheating (tracking phenomenon) in the thermostat, electronic board, starting relay, etc., and overheating of the heating device (Band Heater). there is. Therefore, in order to prevent fires from these devices, a system to remove foreign substances inside the water purifier is necessary, the use of heat-resistant (fire-resistant) wires for electrical devices is essential, and the use of non-combustible materials (semi-combustible materials) for each part is necessary to prevent fire. The risk must be eliminated through prevention and combustion expansion prevention devices.

  • 본 연구에서는 다중이용업소의 안전관리에 대한 법적 운영실태 분석과 다중이용업소에서 발생한 대형화재 사례분석 등을 통하여 다중이용업소 화재 및 안전관리에 대한 문제점을 도출하고 재발 방지를 위한 개선책을 제시하고자 한다. 연구를 위하여 먼저 다중이용업의 이론적 고찰을 통하여 업종의 현황과 화재 발생 현황 등을 조사한 후 다중이용업에 대한 선행연구 분석을 하였다. 그리고 법적·제도적 현황을 분석하여 충청북도 제천 화재, 인천 인현동 화재, 서울 송파구 화재 등의 사례를 통하여 문제점을 도출하였다. 그 결과, 첫째, 화재 초기대응 능력 강화의 필요성. 둘째, 비상구 유지·관리의 철저. 셋째, 실내 장식물의 합리적인 규제의 필요성. 넷째, 소방안전 교육·훈련의 강화. 다섯째, 소방 및 안전시설 등의 설치 기준 강화. 여섯째, 안전관리에 대한 경각심의 고취가 필요하다는 결과를 도출하고 법·제도적 내용과 비교·분석하여 이에 따른 해결방안을 제시한다. 다중이용업소 화재의 원인을 보면 건물주, 영업주, 종사자들이 자기 영업장에서 화재가 발생할 리가 없다는 생각을 가져 경각심이 부족하다. 소방관서와 관련 행정기관의 교육과 홍보를 통하여 경각심을 고취시켜야 할 것이다.

  • In this study the artillery fire system is investigated in consideration of the characteristics of the troop and the target. Two kinds of decision are to be made on the target allocation with fire ammunition and the fire sequencing for the target with duties in charge. The objective is to minimize the completion time for all troops. Each target has the specified amount of load of fire, which can be accomplished by a single troop or the combination of the troops having different capabilities. Mathematical model is suggested, and the heuristic algorithm which yields a solution within a reasonable computation time is developed. The algorithm consists of iterative three steps : the initial solution generation, the division improvement, and the exchange improvement. The performance of the heuristic is evaluated through the computational experiment

  • Recently, in circumstantial situation it is recommended positively to utilize of EIFS(Exterior Insulating and Finishing System) as energy policy for economizing energy. But internal EPS insulators of EIFS are exterior panel of high fire risk, because of constituting of flammable materials to be fragile in fire. In this study, fire risk is assessed by experiment Con Calorimeter test and SBI(Single Burning Item) test. As the result of experiment, Con Calorimeter tests do not reach to capability standard of internal incombustible grade, and are assessed as low grade in SBI incombustible grade. Because EIPS is exterior material in buildings with high fire risk in spite of good efficiency, it is required rapidly to take measures to meet situation through various studies(for instance, adjusting law regulation, etc.) in the future.

  • In this study, we propose a new Fire Flame Region Extraction using Block Homogeneity Segmentation method of the Fire Image with irregular texture and various colors. It is generally assumed that fire flame extraction plays a very important role. The Color Image with fire flame is divided into blocks and edge strength for each block is computed by using modified color histogram intersection method that has been developed to differentiate object boundaries from irregular texture boundaries effectively. The block homogeneity is designed to have the higher value in the center of region with the homeogenous colors or texture while to have lower value near region boundaries. The image represented by the block homogeneity is gray scale image and watershed transformation technique is used to generate closed boundary for each region. As the watershed transform generally results in over-segmentation, region merging based on common boundary strength is followed. The proposed method can be applied quickly and effectively to the initial response of fire.
