The absence of fire fighters' connection to communication can bring about increased loss of life due to errors and delays in rescue and actions and danger to their own safety. Therefore, when communication infrastructure has been destroyed in an enclosed space, it is necessary to set up an emergency wire or wireless telecommunication environment to fire fighting and to secure safer environment to deal with the disaster by checking the location of fire fighters. In this research, for the establishment communication environment in an enclosed inside using Ultra-Wide Band (UWB) wireless communication network, the performance of communication position determination of a single UWB communication module was evaluated regarding 6 kinds of indoor surroundings. When the communication distance in an indoor environment of each 6 channels bandwidth of UWB communication frequency was measured, the results were as follows: the open space (Ave. 15.5 m, Max. 20 m), the corridor (Ave. 17.33 m, Max 20 m), inside retaining home furnishings (Ave. 15.3 m, Max. 20 m), vertical stairs (Ave. 4.33 m, Max. 6 m), horizontal space with a closed fire door (Ave. 6.5 m, Max. 17 m). It was also found out that the communication function and the distance function were best in the frequency range from 6489.6 to 1081.6 MHz by 7 Ch. Accordingly, the establishment of communication environment in an enclosed space is judged to be possible when UWB communication module is set up at 20 m apart and multiple channels are used.

In case of plant accident, the most important measures that field operators, control-room operators and fire fighters must take are the escape from and going into the accident sites. These two different actions are reverse directional moving actions. By training operators and fire fighters with counter-accident path taking measurements, we can prevent the small accidents from becoming large-scale accidents, and can take efficient measurements in case of actual plant accidents. Out of necessities of path-taking training, in this research, we developed the escape and rescue path-taking method for plant accident response training. We can calculate the escape and rescue routes from a operator or fire fighter's current location as of accident happening and provide route data which in turn can be used as the safety training scenario. We expect this path-taking method can enhance the effectiveness and reality of escape and rescue training scenarios.

In Seoul, there are lots of skyscrapers that have above 60 stories and buildings that have more than 8 basement levels, as well as massive distribution complex region which is connected to subways, departments, malls, hotels, and exhibition halls. When an accident, such as fire and explosion, happens in these areas or structures, if we can't find where fire-fighters are, who go into the building to suppress the fire, we couldn't be sure of their safety as well as effective command. Actually, it may cause much more damage itself and restrict either fire suppression or lifesaving. To protect people's life and properties as much as possible, this study will show the method to construct system of disaster-management supports with effective operation of fire force and scientific fire strategy in the scene by using Ubiquitous technique to enormous disasters.

In recent years, the surroundings of Fire have rapidly changed and citizens need for Fire have been demanding very high. Under these situations, in order for satisfaction to all these demands, Seoul Metropolitan Government Fire Academy(SFA) have only to improve its educational training program as the fire educational training center in Korea. The purpose of this study is to scrutinize current educational training program of SFA and measure the relative weight among the hierarchy of disaster management(prevention and mitigation-prepare dness-response-recovery) by using the Analytic Hierarchy Process(AHP). The result of this study presents that how many hours must be allocated and set the educational training program with scientific and systematic way of AHP compared the current program of SFA in 2013. And This study is applied to increase access and comprehension about the AHP and will be able to present guideline for the selection of optimal the educational training of SFA to serve Seoul citizens the best Fire services.

소방보호복은 화재진압현장에서 소방관들을 화상 위험으로부터 보호하기 위해 가장 많이 착용하는 장비이다. 소방보호복의 열보호 특성을 정확히 파악하고 있어야 소방관들의 화재진압작업시 위험요소를 적절히 판단하여 화상 사고 등을 예방할 수 있다. 따라서 본 연구는 복사열 노출에 따른 소방보호복의 열보호 성능을 정확히 측정 및 분석하기 위해 실험 장비를 제작하고 실험을 수행하였다. 소방 보호복의 구성 재료 각각에 대해 복사열 노출을 시켜 시간에 따른 피복 전후면의 온도차와 통과 열유속을 측정하여 소방 보호복의 열보호 성능 특성을 살펴보았다.

화재 현장에 투입된 소방대원들은 각종 위험한 환경에 장시간 노출된 상태로 활동을 하고 있으며 또한 열과 연기 등으로 인하여 시야 확보가 매우 어렵고 장시간 화재 진압 및 구조 활동으로 인하여 급격한 체력 저하로 야기되는 소방대원의 인명 피해가 발생되고 있다. 그러므로 본 논문에서는 이러한 인명 피해를 막기 위하여 투입된 소방대원의 위치 추적 및 상태 등을 확인하여 만약에 고립된 소방대원이 있을 경우 안전하게 탈출 할 수 있는 실내 측위 및 추적 기술에 대하여 연구한다.

Because the average span of human life is expanded by developing economy growth and medicine science elder population increases rapidly. According to that A first aid patient of demands grow, too so in a fire station. We have to prepare following these. First that the silver ambulance is in process of service is widely. second, medical teams and fire fighters construct unity Third, New curni culum makes under modern operating course. Forth, the problem that wireless paging system sets up and rums already. advances more effective. Fifth furthermore, we organize a private volunteer for an old age To connect that we enlarge total service for silver age. Through this fire fighting service. we are neloom to get more confidence and love.

The use of special gas masks such as PAPR is strongly required for the safe and efficient work of fire-fighters in removing fire residue and rescue activity. Special gas masks commonly use canisters with carbon activated particles. This paper analyzed the pressure distribution, velocity distribution and pressure loss characteristics in canisters using CFD simulation, and showed pressure drops are affected by inlet air velocity, canister geometry and increase dramatically especially with the decrease of particle diameters and volume fractions.

Among the firefighting facilities, the fire department connection during firefighting is more important than any other facilities at the firefighting site to supply fire water. This study examined the water supply port of a fire department connection installed at an apartment building based on the Standard for Fire Safety (NFSC 502). The time of discovery was measured by fire fighters who knew or did not know of the water supply port installed in the apartment building, and by separating day and night. To maximize the use of the fire department connection which is the full fire extinguisher facility used by the fire brigade based on the results of the experiment, the author suggests improvement proposals that can clarify the installation location and install the location sign of the fire department connection for the Standard for Fire Safety (NFSC 502).

Till now disaster management is limited to be performed usually by the government. However, government has its limits to carry out disaster management effectively. Thus, diverse organizations and groups such as related agencies, citizens, NGOs, companies, are required to be formed as a multi-organizational cooperation system that is governance of disaster management. This research deals with concepts of disaster management, governance. Therefore, this study presents that effective disaster management plans such as citizens' support and cooperation with related agencies, forming professionalism and active cooperation with disaster management between volunteering and volunteer fire department and well-organizing NGO network, by minutely understanding the concepts of disaster management, governance and others and also positively analyzing influence factors of efficiency of disaster management.
