  • 지하에 건설되는 터널은 구조상 반 밀폐적인 특성을 가지고 외부와 차단되어 있기 때문에 화재발생시 연기에 의한 질식의 위험성이 크고 다수의 이용자들이 쉽게 패닉현상에 빠지게 되고 많은 연기와 유독가스에 노출되어 생명의 위협을 받게 된다. 또한 연기와 유독가스 호흡에 의한 체내유입은 인체상의 여러 가지 부작용을 초래하는 등 피해를 가져올 수 있다. 이러한 피해를 예방하고 최소화하기 위해 방재설비를 시설하고 운영하는데 국내의 방재시설에 대한 규정은 지하공간을 관리 관장하는 기관과 용도에 따라 각각 다르게 적용하고 있어 터널관련 방재시설의 변천에 대하여 알아보고 현재의 설치 기준과 문제점을 살펴보았다.

  • Since subway fire disaster at Daegu, Korea smoke control system and passengers evacuation distance has been focused to reform. Existing smoke control facilities need to expand volume of ventilation capacity however, the complicate subway station structure can hardly react dispersion of smokes from massive subway cabin fire. Smoke flow at platform level move upward thought vertical stairway and passengers evacuation goes with same direction. The victims of evacuees from subway station fire mainly due to exposure of heat radiation and smoke. The study demonstration the effect of downward evacuates stairway system by separating evacuation route to smoke movement pass way including saving times of evacuation.

  • Exposure of nonsmokers to environmental tobacco smoke (ETS) has been claimed to be associated with an increased risk for lung cancer e. g., in the US, Europe, Japan and several Asian countries. The present paper reports on and discusses the scientific evidence available to date that can be used in order to assess this potential risk for Korea. Evidence related to three key steps in risk assessment, i.e., the characterization of a potential risk, data associating a response to a dose, and data characterizing actual exposures of people to ETS will be reviewed. The final assessment of the potential risk will be left to those qualified and commissioned with the task of risk assessment as a basis for public health policy in Korea.

  • 최근의 건축물은 다양한 소재의 마감재를 사용함으로서 화재 발생시 다양한 연소가스를 배출한다. 이때 건축물 내부의 화재에 노출된 재실자는 열 및 화상의 위험성과 함께 연기 및 독성가스의 피해를 받기 쉽다. 본 연구에서는 건축물 화재시 발생될 수 있는 HCl에 대한 표준가스를 제작하여 가스유해성시험을 수행하고, HCl 표준가스에 노출된 실험용 쥐의 표적장기적출실험을 수행하였다. 이를 통해서 유독가스에 노출된 실험용 쥐의 해부를 통한 표적장기-심장(Heart), 간(Liver), 폐(Lung), 비장(Spleen), 신장(Kidney), 흉선(Thymus)-의 손상여부와 KS F 2271에 의한 평균행동정지시간과의 관계를 분석하였다.

  • The aim of the research is to estimate the effect of smoke and combustion gases on humane body indirectly through measuring the toxicity of those. For this purpose, the toxic index of smoke and combustion gases was investigated by smoke hazard test and analysis of smoke which were conducted by KS F 2271 and NES 713 method respectively. It i s proved by KS F 2271 method that PASCON trough is suitable to the testing standard of interior material and construction of building. In addition, it is identified by NES 713 method that combustion gases occurring in PASCON product were only carbon dioxide and carbon monoxide, and the smoke index of those was 0.944. This value means that the hazard effect of smoke gases on humane ! body can possibly happens when exposed to the smoke gases for more than 30 min. In aspect of the domestic situation that have not regulated the hazard estimation and the emissions of smoke when the flame retarding ability of the products have been requested, the toxic indexes of PASCON products are comparatively low.

  • In this paper, we propose a model for detecting efficient fire identification to prevent fires that can lead to various industrial accidents, farmland and large forest fires, with the widespread use of various chemicals and flammable substances as modern technology advances. This paper presents an algorithm that can detect fire smoke in a high-efficiency and short time using images, and an algorithm based on SVM(Support Vector Machine) and K fold cross-verification technologies. By analyzing images, fire and smoke detection algorithms have relatively superior detection performance compared to existing algorithms, and the analysis of fire and smoke characteristics detected in this paper is analyzed stably and efficiently and is expected to be used in various fields that may be exposed to fire risks in the future.

  • The onset of fire on the International Space Station (ISS) is a critical problem that can threaten the life of crew members onboard and thus instantaneous fire detection and extinguishment technology has been considered as one of the most important aspects in the ISS operation. In the present study, a numerical analysis was performed to better understanding of the characteristics of smoke behaviors and detection in a pressurized module of the ISS using the NIST Fire Dynamic Simulator (FDS). Numerical results indicate that the smoke flow patterns under zero-gravity condition are clearly different from those under normal gravity condition. In addition, the results obtained from numerical simulations coupled with the PM internal flows are expected to provide basic and useful information in designing the microgravity fire detection devices and establishing in fire response protocol for astronauts or the crew members.

  • 최근에는 직접 흡연 뿐만 아니라, 간접 흡연에 의한 인체 유해 영향에 대한 가능성이 공중 보건 문제의 하나로 그 중요성이 증가하고 있다. Brownson등은 1997년 간접 흡연이 폐암의 위험을 증가시킨다는 보고를 하였으며, 간접 흡연은 아동들의 호흡기 질환을 증가시켜 흡연자 가정에 가는 아이들은 비흡연자 가정에 사는 아이들보다 호흡기 감염(기관지염, 폐렴)에 더욱 민감하다고 보고되고 있다(Greenberg, 1988; Zmirou D 등, 1990; Tredaniel J 등, 1989). 따라서 최근에는 간접흡연자들의 환경중 담배연기(ETS) 노출의 잠재적인 건강 영향에 대한 관심이 증가하고 있는 추세이다.

  • 소방 장비의 개선은 구조 활동의 효율성을 높여서 인명 구조율을 높일 수 있다. 또한 고온에 노출되는 시간, 사고 위험에 노출되는 시간을 줄이기 때문에 소방관의 사망 확률도 줄일 수 있다. 그래서 기존 장비의 열악했던 사항들을 개선한 디바이스를 개발했다. 화재 현장에서 인명 구조 시 소방관이 연기속에서의 시야 확보, 원활한 무전 통신, 각 대원들의 위치 파악과 실시간 산소통 잔량 확인 기능을 갖춘 장치를 개발했다. 이에 따라 구조작업의 효율성이 크게 증대 될 것이다.
