  • Purpose: The purpose of this study is to present the direction of improvement of safety management by reviewing the current status of forest fire accidents that are becoming larger throughout the year and the problems of the response system. Method: Domestic and foreign literature survey and statistics of recent forest fire accidents by Statistics Korea investigated and analyzed the cause, number of damage, and suggested ways to improve forest fire safety management through domestic and foreign forest fire response systems. Result: Through the analysis of the causes of recent wildfires and overseas response cases, measures to improve the safety management of wildfires in terms of hardware, software, and humanware were derived. Conclusion: The plan to improve forest fire safety management was classified into three main categories and presented, and it should be embodied through further related research.

  • The purpose of this study was to verify the change in temperature humidity perspiration of fire suit when applying phased intensive exercises to fire fighter wearing fire suit. For this study, three male fire fighters took basic physical test and performed 10 minute phased intensive exercises -exercise intensity I (30%VO2max), exercise intensity II (45%VO2max), exercise intensity III (60%VO2max) based on maximum oxygen consumption (VO2max)- wearing fire suit (helmet, boots, air respirator) in treadmill and took a rest. The result of study shows that the temperature in the suit elevated during stabilization period after each exercise intensity, humidity elevated as exercise intensity increased, perspiration elevated as exercise intensity increased. This study indirectly ascertained the fire suit's physiological change in fire fighters during field activities.

  • In this study, the algorithm for priority area of forest fire surveillance was developed to enhance the effectiveness of fire detection. The high priority surveillance area for forest fire detection was defined as the area with not only low value of viewshed analysis of the lookouts and detection cameras but also high fire occurrence probability. To build the priority map, fuzzy function and map algebra were used. The analysis results of Bonghwa-gun, Gyeongbuk Province, showed that the surveillance priority of central and southern area is higher than north area. This algorithm could be used in the allocation of fire prevention resources and selection of suitable point for new fire detection system.

  • In order to investigate the strength recovery of fire-damaged concrete after post-fire curing, concrete specimens were heating at $2^{\circ}C/min$ or $5^{\circ}C/min$ to 400, 600 and $800^{\circ}C$, and these exposed specimens were soaked in the water for 24 hours and following by 29-day post-fire curing. The compressive strength and split tensile strength of the high-temperature-exposed specimens before and after post-fire curing were tested. The proportion of split aggregate in the split surfaces was analyzed to evaluate the mortar-aggregate interfacial strength. After the post-fire curing process, the split tensile strength of specimens exposed to all temperatures was recovered significantly, while the recovery of compressive strength was only obvious within the specimens exposed to $600^{\circ}C$. The tensile strength is more sensitive to the mortar-aggregate interfacial cracks, which caused that the split tensile strength decreased more after high-temperature exposure and recovery more after post-fire curing than the compressive strength. The mortar-aggregate interfacial strength also showed remarkable recovery after post-fire curing, and it contributed to the recovery of split tensile strength.

  • Purpose: The purpose of the study is to investigate the actual state of activity on domestic and foreign civil anti-disaster organizations, related suggestions, and development plans. Methods: This study used the documentary survey research method and the technical approach method. Civil anti-disaster organizations' information was derived from detailed scholarly monographs, specialty publications, and previous studies of master doctorate dissertation. Results: Volunteer Fire Department and voluntary crime prevention groups show problems related to budgetary deficits and volunteer deficiency. In order to resolve these issues, laws must be enacted to guarantee interest and support. In addition, the Citizen Corps Active in Disaster (CAIND) organization requires a dedicated salary system to address the investment of its workforce and the cost of heavy equipment. Moreover, deficiencies were revealed regarding the lack of systems in support of occupational education and training. In conclusion, several weak points require close attention. Conclusion: The results of this comparative analysis study about the domestic and foreign civil anti-disaster organizations provide insight into identity materialization and concept establishment.

  • As recent Jecheon and Milyang fire cases show, the need for fire disaster training to prepare for a fire disaster continues to grow. In the event of a disaster, people become mentally confused and are called disaster personalities. In order to survive in a disaster, it is necessary to develop the power to overcome the disaster personality by experiencing the disaster situation in advance. Therefore, training to overcome disaster personality is needed, and virtual reality can be a good training means in that it can experience without physical space. In addition, periodic actual disaster evacuation drills should be carried out to compensate for the shortcomings of virtual reality. In order to introduce fire disaster drill using virtual reality and to spread it to the public, the Korea National VR project should be introduced which benchmarked national PC project which succeeded in the past informatization project. Besides, the Korea National Safety Point system should be integrated to cover disaster preparedness training and building reinforcement. If the national VR project and the national safety point system are introduced successfully, Korea will be the basis for escaping the disgraceful nickname of 'disaster republic'.

  • 본 연구에서는 재실자의 밀도가 높은 지하상가는 공간의 특성상 화재가 발생할 경우 다량의 유독가스의 발생 및 연기의 이동경로와 인간의 피난경로 일치로 인하여 피난안전에 큰 위험성이 있다고 사료된다. 이에 지하철 역사와 연결되어 있는 지하상가를 선정 후, 일본 피난안전성평가수법과 FDS(Fire Dynamic Simulator) 및 SIMULEX를 이용하여 비교 분석을 하였으며, 그 결과, 화재발생 후 6분이 경과 시 위험한 것으로 판단되었다. 그에 대한 대책으로 자연 배연구를 설치하여 시뮬레이션 수행을 한 결과 가시도확보 및 각 출구에서의 온도가 하강하는 것을 확인할 수 있었다.

  • 우리나라는 최근 건축물 화재 및 시장화재가 지속적으로 증가해 왔다. 이 중 시장화재는 일반적인 화재와 달리 대형화재로 확대될 위험성이 높다. 본 연구에서는 종로구 신진시장 화재사례를 중심으로 시장화재 전파과정을 분석한 결과 지붕을 통한 화염전파가 주된 확대원인인 것으로 나타났다. 따라서 향후 이러한 전파과정을 고려한 화재위험성평가수법의 개발이 필요하다고 판단된다.
