  • Since 1992, conventional fire fighting businesses have been converted into a metropolitan autonomous fire fighting system to be ready for a variety of disasters. However, the corresponding investment has been overlapped due to the non-integration of businesses to prevent any potential disasters, and a series of collaborative systems have been not functioning so well. In the meantime, our fire fighting sector has been trying to set up its own clean and faithful position by abolishing any inconvenient system or outsourcing private sectors, and expanded its work scope from conventional fire fighting even to rescue and emergency works. While focusing on handling disaster, the fire fighting sector has been widely trusted and reliable throughtout our nation. Moreover, our fire fighting sector has secured nation wide mobile organizations, technical personnel by field, special equipments and independent communication network. In addition, the fire fighting sector has knowledges, expertise and capabilities required for managing disasters, while in charge of almost every disaster management works including fire, explosion, collapse, disaster and flood. It becomes an organization for comprehensive disaster management under an absolute national trust, which is based on the system for prevention, preparation and countermeasure against a variety of disasters. Thus, our fire fighting sector must make many efforts and try to modernize conventional education and training. The ways to facilitate rescue and emergency works may include the nurture of technical fire fighting personnel along with modernized equipments, the reinforcement of rescue and emergency education, the facilitation of operating civil defense corps, the facilitation of operating volunteer fire fighting corps, the better arrangement of 119 briefing room for public healthcare in provincial offices, the sterilization of rescue instruments and equipments the better repair education for emergency rescue member, the establishment of regional emergency assistant system and the expansion of fire fighting personnel and equipments. In terms of reinforcing the functions and services of rescue 119 and emergency corps, we must review the following considerations: Building up security system along with operational expansion, building up a system for emergency medical treatment, building up a comprehensive information management system for rescue and emergency, constructing a provincial safety museum and so forth. For the ways to better the works of rescue 119 we can review the following considerations : Improving the education for fire fighting training corps under Jeju Provincial Fire and Disaster Management Department, providing rescue members with more opportunities for clinical practices, enhancing the morale of rescue members, installing a comprehensive briefing room for emergency rescue members, building up medical networks along with reasonable policies for information service, operating the consulting system for rescue 119 and so on. If these requirements are met, it is expected that the fire fighting departments in Jeju province can cope with every accident and disaster a little more rapidly and quickly in compliance with local needs, so that they can keep their own position as a public fire fighting organization which may be trusted by the public.

  • Instruction and prevention of the safety for a fire have been performed continuously by nation. However, the accident due to a fire is not decreasing and causes a serious calamity to people. It is at the initial stage of fire burning that the most effective way to reduce damage is to evacuate and fight a fire. When a fire burns, the equipments reporting to other person or organization concerned are called 'acoustic reporting equipment'. Among those equipments reporting to person, 'a fire bell' is the easiest equipment to approach. Observing the behaviors of people when a fire burning, some are in a quiet indoor, some in a room with other people, some in a square with many people and some in indoor filled with smoke etc. This study aims to find out an acoustic reporting signal appropriate for visual information. For the experiments, visual-auditory experiments were performed through reporting signals and visual informations with several situations that is able to be faced at when a fire burns.

  • 강화플라스틱(FRP) 선박은 화재 시 화염확산을 막기 위하여 관련 구조 기준에 따라 기관실 주위 벽 내부를 난연성 수지로 3회 이상 적층하거나, 이와 동등한 방열재로 둘러싸야한다. 관련 난연성 적층용 수지 및 일부 난연재료(연질폴리우레탄복합체)의 경우 선박용 물건의 형식승인 시험기준에 따라 그 성능을 평가할 수 있으나, 방열재로 빈번하게 사용되고 있는 '겔코트'에 대한 성능기준은 명확하지 않은 실정으로 난연성 수지와 화재안전성능이 비교 평가된 바 없다. 본 연구에서는 FRP 선박을 건조하는 조선소를 대상으로 설문조사를 실시하여 사용 중인 난연성 수지 3종, 겔코트 4종, 방염도료 1종 및 폴리우레탄 복합재 1종에 대해 화염전파시험과 방염성능시험을 적용하여 그 성능을 비교하였다. 화염전파시험 결과 임계열유속(CFE) 기준으로 각 종별 평균값을 비교하면 폴리우레탄 복합재, 난연성 수지, 방염도료, 겔코트 순으로 양호한 것으로 나왔고, 겔코트는 3회 도포한 것이 6회 도포한 것보다 양호한 결과를 보였다. 방염성능시험 결과 탄화면적 기준으로 각 종별 평균값을 비교하면 방염도료가 가장 좋게 나왔고 난연성 수지와 겔코트는 유사한 수준으로 나타났다.

  • 비정상(unsteady) 화재성장이 발생되는 반밀폐된 구획에서 환기부족화재의 열 및 화학적 특성에 관한 FDS(Fire Dynamics Simulator)의 예측성능 평가가 수행되었다. 이를 위해 실규모 ISO 9705 표준 화재실의 출입구 폭이 0.1 m로 축소되었으며, spray 노즐을 통해 Heptane 연료유량은 선형적으로 증가되었다. 수치계산에 대한 신뢰도 확보를 위하여 동일 조건에서 수행된 실험결과와의 상세한 비교가 이루어졌다. 적절한 격자계를 이용한 FDS의 결과는 구획 내부의 온도 및 열유속(heat flux)은 비교적 잘 예측하지만, 비정상 CO 및 $CO_2$ 생성특성은 적절히 예측하지 못함을 확인하였다. 이러한 결과는 최근 수행된 유사조건의 정상상태 환기부족 구획화재에 대한 FDS 예측결과와 상반된 것으로서, 반밀폐된 구획화재 모델링에서 FDS를 이용한 비정상 CO 생성특성 예측에 상당한 주위가 요구됨을 확인하였다.

  • 본 연구는 두 가지 유형의 아트리움 공간에 대해서 Zone모델과 Field모델을 비교하였으며 특히 천장에 열 유속을 갖는 아트리움 화재에 대해서 SMEP화재 모델을 적용하여 연기거동을 수치해석 하였다. Zone 모델로는 NIST에서 개발된 CFAST 그리고 CSIRO에서 개발된 NBTC 1-room 모델을 사용하여 SMEP Field모델을 검증하였다. PISO 알고리즘과 부력항을 포함한 수정 k-e epsilon 난류모델을 사용한 SMEP은 연속, 운동, 에너지 그리고 농도 방정식을 풀었으며, 상용 Zone 모델들과의 비교는 서로 유사한 결과를 보였다. 천장이 유리로 만들어진 아트리움의 경우, 태양열에 의한 천장 열 유속을 고려함으로써 좀더 실제적인 화재현상을 규명할 수 있다. 수치해석결과 천장 열 유속 조건은 연층의 온도 분포에는 영향을 미치지만 연기의 하강과 거동에는 커다란 영향을 미치지 않고 있음을 확인 할 수 있었다. 따라서 화재 감지기나 배연 설비 시스템의 설치시 이러한 점들이 고려되어야만 한다.

  • As a result of analyzing problems in field practice and its effects, the following conclusions can be obtained. Man students were more satisfied with their choice of this department than woman students and woman students recognized the importance of hospital practice although they felt the need of fire fighting station practice and man students felt the necessity of hospital practice, but they answered the fire fighting station practice was important. Departments of field practice are emergency and nurse departments in hospitals and emergency aid section in fire fighting stations. And it is found that field practice was performed well in relation to major subject. Areas of practice included emergency room, operation room and extensive cure unit and the experience of ambulance was more in fire fighting station than in hospital. Clinical guidance of professor was preferred to once a week and the students answered they felt satisfaction with practice through conference. Answer that field practice was helpful in understanding class was very high as 96.8% and its connection with employment was low as 12.8%. It is found that a proper timing of field practice was winter vacation for hospital practice after completing the second semester of the first year and summer vacation for fire fighting station practice after the first semester of the second year. The most difficult department in field practice was nurse department in hospital because 'respondents were practice students' and administrative department in fire fighting stations because 'they lacked recognition of paramedic'. In making practice diary, 'describing measure results' was difficult most and the respondents wanted to keep the diary in their custody.
