This paper analyzes the relation between fire shutters and fire spread by conducting fire simulation on inner space with fire shutters. Using Fire Dynamics Simulator (FDS), a commercial fire simulation software, the simulation is done on an ideal inner robby, where fire size and the open/close of fire shutters are varied. Our simulation environment can derive significant fire parameters such as temperature variation of fire room walls and entrances of refuge stairs, variation of carbon dioxide, and soot spread. According to the simulation results, temperature and carbon dioxide distribution in refuge stairs have little dependence on vent open or close, but the part close of fire shutters blocks soot inflow to refuge stairs.

Today, with the development of technology and industry, fire accidents in special buildings are increasing as special buildings increase. However, despite the rapid development of information and communication technology, human casualties are steadily occurring due to the underdeveloped and ineffective indoor fire alarm system. In this study, we confirmed that the existing indoor fire alarm system using acoustic alarm could not deliver a sufficiently large alarm to the in-room personnel. To improve this, we designed and implemented a fire alarm system using edge computing and beacons. The proposed improved fire alarm system consists of terminal sensor nodes, edge nodes, a user application, and a server. The terminal sensor nodes collect indoor environment data and send it to the edge node, and the edge node monitors whether a fire occurs through the transmitted sensor value. In addition, the edge node continuously generate beacon signals to collect information of smart devices with user applications installed within the signal range, store them in a server database, and send application push-type fire alarms to all in-room personnel based on the collected user information. As a result of conducting a signal valid range measurement experiment in a university building with dense lecture rooms, it was confirmed that device information was normally collected within the beacon signal range of the edge node and a fire alarm was quickly sent to specific users. Through this, it was confirmed that the "blind spot problem of the alarm" was solved by flexibly collecting information of visitors that changes time to time and sending the alarm to a smart device very adjacent to the people. In addition, through the analysis of the experimental results, a plan to effectively apply the proposed fire alarm system according to the characteristics of the indoor space was proposed.

화재는 여러 가지 요인들에 의해 복합적으로 작용하는 현상이다. 특히 건물화재는 다분히 3차원적이고 무수히 많은 변수들에 의해 그 피해 규모가 급속히 커져가고 있는 추세에 있다. 건물화재는 각 국가의 고유한 사회 문화적 수준과 환경에 따라 큰 차이가 있으므로 선진국의 연구결과를 그대로 국내의 상황에 적용하는 데는 다소 무리가 있다 따라서 좀 더 많은 실험을 통한 우리의 환경에 좀 더 가까운 실험 데이터 및 결과가 필요하다(중략)

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.

It is very dongerous for ship‘s fire which occurs from navigating because of it will not be able to expect fire fighting from land so that handle with the oneself to control. Additionally, in the case of passenger ship is more serious for the reason of not only the property damage but also large life accident can be occurred continuously. When the fire occurs, the many smoke to occur simultaneously as well as the heat from combustion process and the poisonous smoke is brought the life damage as the death from suffocation The purpose of this study is to examine the smoke movement characteristics in the ship's indoor spaces with fire size and location An experimental study was carried out with two sized of fires and three typed of fire source locations. As the results, the smoke and heat diffusion characteristics Ms been showed the most quick rise curve in the case of comer type fire.

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.

본 논문에서는 승용자동차에 대한 소화기 비치 필요성 및 소화기의 효용성 및 적정성에 대해 평가하고자 한다. 이를 위해 소방청 국가화재정보센터에 입력된 차량화재를 분석하였으며, 국외 자동차용 소화기 비치기준을 조사하였다. 또한, 자동차를 대상으로 한 시뮬레이션 선행연구 결과를 분석하여 다른 차종에 비해 승용자동차의 위험도가 가장 높다. 한편, 기존의 시뮬레이션 연구결과를 분석해보면 소화기를 이용한 초기진화가 가능한 황금시간은 실내화재 시 2분, 엔진룸화재 시 약 7분 정도임을 알 수 있다. 이는 승용자동차 화재 시 소화기를 이용한 초기소화가 절실하다고 할 수 있다. 따라서 승용자동차 화재로부터 국민의 안전과 재산을 보호하고 국내 자동차 안전환경 및 자동차 안전기준을 국제기준에 맞춰 국제 경쟁력을 확보하기 위해서는 승용자동차에 소화기 비치를 의무화할 필요성이 있다.
