Aircraft fires due to accident at an airport may be under a special situation. An outstanding characteristic of aircraft fires is their tendency to reach lethal intensity within a very short time. In domestic aviation act, there are regulations related to services coping with the aircraft accidents within an airport. To cope aircraft fires, it is necessary to define clearly the regulations and standards about the services and related activities of rescue and fire fighting, and to keep the regulations and standards. The study has been performed on the basis of International Civil Aviation Organization (ICAO) Airport Services Manual of rescue and fire fighting. The objective of study is to suggest improvement methods for standards applicable to actual service practices of rescue and fire fighting by analyzing through the comparison of domestic and international regulations and standards.

In our country, a number of fire outbreaking had been increased suddenly for 20 years from beginning of 1980's to 2001. That was related with the focus of economic policy, the rapid increasing of fire fighting objects, the change of life environment, and the increasement of usage of energy. Accordingly, we tried to enforce the function of feedback effect of fire prevention policies with analysing the trends of fire occurring from 1950's to 2006 and the correct statistical analysis.

Water mist fire suppression system utilizes the fire suppression features such as cooling of fire source, dilution of ambient oxygen, and shielding of radiation heat with the evaporation of microscopic water droplets. The momentum of water mist is relatively low and the infiltration of water mist to the fire source is not effective. In addition to lower penetration force, the evaporated water vapor is liable to decline to limited portion of fire source due to its light weight and sparse density. On the other hand, the cycling water mist system is expected to improve the penetration force of water mist as well as the dilution coverage capability with the stratified spray characteristics. At this paper we present the analyzed fire suppression capability of intermittent water spray pattern by use of FDS which is computational fire dynamics fire model. We expect this analysis shall be supportive to the development of the prototype of water mist nozzle.

가스계 소화설비의 배관이 장거리 배관인 경우 소화약제 저장탱크의 선택밸브가 개방된 다음 소화약제가 화재지역에 방출될 때 까지 일정시간이 소요된다. 또한 소화약제 배관 내부의 공기와 소화약제가 함께 화재지역에 방출되어 소화약제 농도가 희석되므로 소화효과가 감소한다. 이러한 문제점을 해결하기 위하여 소화약제 배관이 방화지역으로 연결되는 지점에서 대기로 연결되는 공기 방출배관과 방출장치를 설치하여 가스계 소화설비의 소화효과를 높일 수 있는 설비 개선방안을 마련하였다.

기존 국내원전의 화재 PSA는 기존 EPRI가 개발한 방법론을 이용하여 화재 PSA를 수행하여 오고 있다. 미국 NRC는 EPRI와의 공동연구를 통하여 새로운 PSA 방법론(NUREG/CR-6850)을 개발하였고, NFPA-805 코드를 적용하는 미국 원자력발전소들에 대해서 이 방법론을 적용한 PSA를 수행하는 것을 권고하고 있다. 본 논문에서는 국내 원전의 참조 주제어실을 대상으로 신규 방법론을 적용하여 노심손상빈도 영향을 평가하였고, 국내원전에 신규 방법론 적용시 논의되어야 할 사항들을 포함하였다.

Purpose: The purpose of this study was to investigate job stress, coping type, and job satisfaction in firefighters. Methods: It was a descriptive study, and 114 subjects were recruited during July to August, 2014. The data were analyzed by t-test, ANOVA (Sheffe's test), and Pearson's correlation coefficient using SPSS/WIN 22.0. Results: The job stress level of subjects was 47.45, coping type was 2.38 and the level of subjects' job satisfaction was 2.97. The job satisfaction was very closely negatively correlated with the job stress (r=-.66, p<.001). Conclusion: These results may contribute to better understanding of stress degree, coping type, and job satisfaction in firefighters. Further follow-up study on firefighters is necessary to relieve their job stress and increase active coping type.

원자력발전소의 방화지역에서 화재가 발생할 경우 케이블의 화재리스크는 온도, 열속, 화염 등 열적 특성에 의해 평가된다. 원전의 안전정지 기능에 사용되는 각종 케이블은 설계관리 및 성능분석을 위해 화재실증실험으로 열적 특성을 실측하여야 하지만 다양한 화재시나리오에 대한 실험 조건 확보와 실험 비용 등 제약이 따른다. 이에 따라 화재모델 FDS (Fire Dynamics Simulator)의 최신버전에 포함된 THIEF (Thermally-Induced Electrical Failure) 모델을 이용하여 국내 원전의 안전정지 케이블에 대한 화재모델링 분석을 수행하였다. 이 연구에서는 케이블이 설치된 형태에 따라 일정 열속에 대한 자켓 온도와 경계조건에 대한 온도분포를 분석하였다. 본 연구 결과 THIEF 모델은 원전 방화지역의 화재에서 안전정지 케이블의 내부온도를 예측할 수 있는 화재모델로 사용가능한 것으로 확인되었다.

Purpose: The purpose of this study was to investigate the mediating effect of perceived appraisal support between neuroticism and occupational stress in firefighters. Methods: The subjects of this study were 156 firefighters who worked at three fire stations in G province in Korea. The collected data were analyzed by t-test, ANOVA, and multiple regression analysis using Baron and Kenny's method for mediation. Results: There were significant relationships between neuroticism and perceived appraisal support (r=.30, p<.001), neuroticism and occupational stress (r=.42, p<.001), and perceived appraisal support and occupational stress (r=.36, p<.001). Perceived appraisal support showed partial mediating effects in the relationship between neuroticism and occupational stress. Conclusion: The impact of neuroticism in firefighters was mediated by perceived appraisal support for occupational stress. This suggests that strategies for enhancing perceived appraisal support in fire fighters should be considered when developing neuroticism management interventions for decreasing their occupational stress.

Purpose: The study aimed to explore experiences of the posttraumatic growth (PTG) in firefighters with repeated exposure to traumatic events. Methods: Participants were 11 firefighters from two fire departments, who had experienced more than one critical trauma events. Data were collected through personal interviews from August to October 2020 and analyzed by Colaizzi's phenomenological methods. Results: The PTG experiences were derived into four categories: 'growth in self-perception', 'rediscovery of the meaning of life', 'deep interpersonal relationships', and 'discovery of the meaning of work'. Conclusion: These findings could be used as basic information for developing PTG program for firefighters such as logo-therapy, semantic therapy, and self-disclosure intervention using expressive writing and speaking.

Purpose: This study conducted a systematic literature review to analyze the factors related to suicidal ideation among firefighters. Methods: A systematic literature review was conducted to identify factors influencing suicidal ideation among firefighters, using Korean academic information search services from January to June 2022. A total of 238 articles were searched using keywords such as "firefighter," "depression," "post-traumatic stress disorder (PTSD)," "cognitive emotion regulation," "suicide," and "suicidal ideation." Among them, nine articles were selected for analysis using descriptive correlation studies. Results: It was found that the relationship between firefighter stress (PTSD) and suicidal thoughts was mediated by depression. Even if the stress level (PTSD) was high, suicidal thoughts decreased when the emotional coping level was high. Conclusion: To prevent firefighters from committing suicide, intervention programs with effective approaches to quickly identify high at-risk people and improve their emotional coping skills, should be implemented.
