This paper aimed to statistically analyze the impact of fire needs not considered in previous reports based on preventive and preparedness strategies of fire administration and fire budget.. The panel data came from 16 metropolitan councils from 2008 to 2018 and was statistically analyzed based on the preventive measures of the fire administration (agreement for building permission, specific target for fire-fighting, public use facilities, and special fire inspection [SFI]), preparedness of the fire administration (fire safety education [FSE]), response of the fire administration (mobilization for fire suppression [MFS] and mobilization for ambulance service [MAS]), and fire budget. In the results, SFI, FSE, and MFS had a significant negative influence on the fire budget. Meanwhile, MAS had a significant positive effect on the fire budget (p < 0.01). These results reflect public policy in Korea; there has been a paradigm shift in fire administration: from disaster acceptance (focusing on recovery) to disaster response (focusing on field response) to disaster preparedness (focusing on preparedness).

This study is a preparation for the application of FSA (Formal Safety Assessment) to the fire safety of ships. FSA is the new-fashioned methodology proposed to prevent ships from the accidents. To make a base of the fire safety assessment about ship's fire protection design and Classification Society rule, statistical informations for the fire safety engineering are investigated. From results, the necessity of new criterion for ship's fire safety design, the need to study the human behavior in the evacuation from fire, and the development of new fire progress model considering special situations in ships are acknowledged.

This article is a study on the activity of rescue workers for designing simulation training scenarios assuming chemical accidents. On the basis of the complexity of the indoor scene in the case of chemical accidents and terrorism, we designed a 12-step simulation training scenario for two teams to analyze the improvement in firefighters' capabilities. On the basis of activity measurement in the simulation scenario, step 2 of training had the most drops in the maximum heart rate, as follow: N1, from 163 bpm to 153 bpm; N2, from 186 bpm to 151 bpm; N3, from 168 bpm to 162 bpm; and N4, from 166 bpm to 152 bpm. In terms of intensity level in the allowable activity time, it was found that in step 2 both N1 and N2 reduced from Level 5 to Level 3, N3 remained at Level 4, N4 reduced from Level 4 to Level 3, and the maximum allowable activity time increased.

최근 국내 고층건물에서 비상훈련이 실시되었고, 이 훈련은 사전 예고한 상태로 화재발생 사이렌과 함께 정해진 시간에 대피를 완료한 사람은 약 20%에 머물렀다는 소식은 우리나라의 안전 불감증의 여전함을 절실히 보여주고 있다. 한편 해상에서는 지속적인 지진 발생 및 지진 발생 회수 증가, 지진 강도도 높아지고 있는 등 지진재해 발생가능성이 높아지고 있지만, 이에 대한 선박 피난에 대한 구체적 대응책 마련은 거의 없다고 할 수 있다. 이러한 해상 상황에서 가장 중요한 역할을 하여야 하는 VTS(Vessel Traffic Service, 해상교통관제)의 의미의 재정립이 필요한 시기이다. 2011년 3월 발생한 동일본 대지진 재해사례의 교훈을 중심으로 한 지진 재난시 우리나라 VTS 대응방안에 대한 제언을 통하여 재난 안전 확보의 가반을 마련하고자 한다.

Purpose: We would like to confirm that the false positive rate of flames/smoke is high when detecting fires. Propose a method and dataset to recognize and classify fire situations to reduce the false detection rate. Method: Using the video as learning data, the characteristics of the fire situation were extracted and applied to the classification model. For evaluation, the model performance of Yolov8 and Slowfast were compared and analyzed using the fire dataset conducted by the National Information Society Agency (NIA). Result: YOLO's detection performance varies sensitively depending on the influence of the background, and it was unable to properly detect fires even when the fire scale was too large or too small. Since SlowFast learns the time axis of the video, we confirmed that detects fire excellently even in situations where the shape of an atypical object cannot be clearly inferred because the surrounding area is blurry or bright. Conclusion: It was confirmed that the fire detection rate was more appropriate when using a video-based artificial intelligence detection model rather than using image data.

Fire monitoring system detects a fire based on the values of various sensors, such as smoke, CO, temperature, or change of temperature. It detects a fire by comparing sensed values with predefined threshold values for each sensor. However, to prevent a fire it is required to predict a situation which has a possibility of fire occurrence. In this work, we propose a fire recognition system using a fuzzy inference method. The rule base is constructed as a combination of fuzzy variables derived from various sensed values. In addition, in order to solve generalization and formalization problems of rule base construction from expert knowledge, we analyze features of fire patterns. The constructed rule base results in an improvement of the recognition accuracy. A fire possibility is predicted as one of 3 levels(normal, caution, danger). The training data of each level is converted to fuzzy rules by FCM(fuzzy C-means clustering) and those rules are used in the inference engine. The performance of the proposed approach is evaluated by using forest fire data from the UCI repository.

소방공무원은 가장 위험한 직업중 하나로 과로사부터 훈련이나 화재진압 현장에서의 사망에 이르기까지 생명의 위험에 노출되어 있다. 이러한 위험성은 소방공무원을 기타 다른 분야의 공무원들과 근본적으로 차이를 가지게 하는 특성으로 작용한다. 소방공무원을 둘러싼 위험을 유발하는 요소들은 치명적 사고로 이어질 수 있을 뿐만 아니라, 스트레스를 증가시키고 있다. 위험 유발 요소들은 제도적 요인, 문화적 요인, 그리고 개인적 경험으로 분류될 수 있고 다시 하위 항목으로 나뉠 수 있다. 본 연구에서는 소방공무원과 관련한 위험유발요인들이 스트레스라는 매개변수를 통해 소방공무원들의 조직몰입에 주는 영향을 고찰하였다.

박물관은 예술과 과학 분야에서 귀중한 문화유산적 가치가 있는 소장품을 보관 전시하는 등 교양, 조사연구, 예술활동 등에 이바지하고 있다. 이러한 박물관의 소장품을 위협하는 요소 중 화재로 인한 피해는 소장품을 순식간에 파괴하여 복구 불능 상태가 될 수도 있어 가장 위험이 큰 재해라고 해도 과언이 아니다. 재난 및 안전관리 기본법 제34조의 6에서는('15년 12월 31일 시행), 다중이용시설 등의 소유자 관리자 또는 점유자는 대통령령으로 정하는 바에 따라 위기상황에 대비한 매뉴얼을 작성 관리토록 되어있다. 하지만 연면적 $3,000m^2$ 이상의 대규모 사립박물관만 해당되며 대다수 사립박물관은 재정적으로 취약하고 소규모 시설로 인해 화재를 비롯한 각종 재난안전관리에 매우 취약하여 소중한 문화적 가치를 지닌 유물들이 소실될 수 있는 높은 위험성을 지니고 있다. 이에 따라 본 연구에서는 중 소규모의 사립박물관 50개소를 선정하여 화재안전에 대비한 소방분야의 관리실태를 점검하고 향후 안전관리 교육 훈련 프로그램 또는 안전관리 매뉴얼 개발에 기초 자료로서 활용 될 수 있는 연구를 수행하였다.

This study analyzes the Required Safe Egress Time (RSET), in the event of a fire at a welfare center for the disabled, using the emergency passage according to the floor arrangement of users to evaluate the safety and the difference in RSET for each emergency passage using the Pathfinder simulation program to suggest an efficient evacuation method. As a result of RSET, it was found that there is no problem in evacuation safety for the current state of the facility's personnel allocation by satisfying the standard RSET in case of fire, and evacuation can be completed safely by evacuating through stairs rather than using elevators if possible. It is necessary for employees to be provided sufficient education and training in advance so that they can evacuate effectively with the disabled in case of fire. This study gives significance in saving many precious lives and safely evacuate in case of fire as evacuation routes were secured through the design, construction and operation of facilities for the disabled and the RSET was shortened through regular evacuation practices. It is necessary to discuss the further RSET studies based on the automatic fire shutters open or not when a fire occurs at a specific location following the installation of automatic fire shutter at the entrance of each floor of the facilities.
