최근 우리나라는 고밀화, 대형화, (초)고층 도시공간에 살고 있으며, 방재도시가 확보되지 않은 곳에서 위험을 느끼며 살고 있다. 이에 따라 대규모 도시공간에서 화재리스크는 점차 높아지고 있으며, 화재 발생시 도시공간내 사람은 생명의 위협감과 더불어 치명적 피해를 입게 된다. 또한 화재발생시 도시화재의 매커니즘으로 인한 대형화재가 발생할 수 있다. 하지만 우리나라는 방재도시 구축에 대한 연구와 도시화재 매커니즘을 고려한 평가시스템이 미흡한 실정이다. 반면 가까운 나라 일본의 경우 이미 대규모 도시화재를 겪어본 바, 이에 대한 실험 및 연구를 토대로 이미 시뮬레이션과 방재도시 구축에 진행중이다. 이에 대해 본 연구는 일본의 대규모 도시화재에 대한 사례 분석을 하고, 우리나라 방재도시 구축을 위한 기초자료를 제시하고자 한다.

최근 건축물은 초고층화 대형화 지하심층화 등으로 변모하고, 더나아가 복합화가 진행되고 있다. 이러한 건축물은 화재 발생 시 기존의 건축물보다 큰 인재로서 다가오며, 특히 연기로 인한 피해가 주를 이루고 있다. 하지만 국내에서는 화재시 피난과 연기의 상관성에 대한 연구 중 이론적 연구는 미흡한 편이다. 따라서 본 연구에서는 화재시 피난과 연기의 상관성에 대한 연구에 기초자료를 제시하고 향후 피난과 연기의 상관성 연구에 대한 하나의 방안을 제시하고자 한다.

최근 주거시설의 내장재는 다양화 되어 가고 있지만 안정성 보다는 디자인, 기능성에 치중되어 그에 따른 화재 위험성도 커져가고 있다. 또한 여러 가지 합성수지로 예상치 못한 화재성상을 보이고 있으나 이에 따른 법규는 미비한 실정이다. 따라서 본 연구는 고정가연물중 주거시설에서 많이 사용되어지는 시료를 선정하여 Cone Calorimeter를 이용해 그 연소특성을 알아보았다. 그에 따른 결과로 바닥재는 국내산이 높은 발열량을 보였고 벽지는 국외산이 높은 발열량을 보였다.

When a fire breaks out, it is difficult to find out the causes of the fire, because combustible things around fire scene are usually burnt away. Among many causes of fires are electronic wires, this thesis deal with the destroyed sheath of electronic wires caused by fire. It was studied with the use of measurement devices focusing on the distinctions of wires and conductors. This study especially emphasized the process of deterioration, burning pattern, and composition of electronic wire conductor. It also has a phenomenological approach to the distinctive cause of fire by some partial force. The fire prevention methods have been suggested through the analysing results of fire patterns. This study is expected to be a useful material for analyzing various electrical fires.

A solar power generation system uses a solar module that collects solar radiation energy, a connecting board that collects DC power generated from the solar module, and a diode to prevent reverse current from flowing from an inverter to the solar module. The existing photovoltaic connection module consists of only fuses and diodes for reverse polarity and overcurrent blocking, and does not have fire diagnosis, prevention, and suppression functions in the event of a fire. To solve this problem, this paper presents a method to monitor the internal state of the photovoltaic connection module using several sensors and to prevent and extinguish a fire using solenoid valves and fire extinguishing agents when a fire is detected. Through the experiment, it was confirmed that the proposed method normally suppresses the fire in event of a fire.

USN Fire Prevention System is an intelligent system that detects the fire through the value which has got from a sensor such as temperature, humidity, intensity of illumination, acceleration, carbon dioxide(CO2) and so on. And then send it to the operator also use the algorithmic fire detection to operate fire extinguish system on. It is among U-Disaster Prevention System which has prevented fire lately. Configuration of the packet was designed to make the most of lightweight and fast processing for low power consumption. Recently listed in the encryption algorithm is applied each DES, 3DES, AES and HIGHT. So objective was to faster encryption than encryption of high-performance finally domestic standard encryption algorithm HIGHT were suitable for the fire prevention system needed frequent sensing time.

A forest fire occurs mainly as natural factor such as wind, temperature or human factor such as light. Recently, the most of forest fire prevention is prediction or prevision against forest fire by using remote sensing technology. However in order to forest fire prevention, the remote sensing has many limitations such as high cost and advanced technologies and so on. Therefore, we need to multisensor integration system that utilize not only remote sensing but also in-situ sensing in order to reduce large damage of forest fire though analysis of happen cause and prediction routing of occurred forest fire. In this paper we propose a multisensor integration system that offers prediction information of factors and route of forest fire by integrates collected data from remote sensor and in-situ sensor for forest fire prevention. The proposed system is based on wireless sensor network for collect observed data from various sensors. The proposed system not only offers great quality information because firstly, raw data level fuse different format of collected data from remote and in-situ sensor but also accomplish information level fusion based on result of first stage. Offered information from our system can help early prevention of factor and early prevision against occurred forest fire which transfer to SMS service or alert service into monitoring interface of administrator.

When a fire occurs in a road tunnel, it is likely to develop into a major disaster because of its sealed structural characteristics. Because of this, a range of disaster prevention facilities should be installed, and they should show their appropriate functions in fire prevention and response. In addition, the installation of essential disaster prevention facilities is missing due to the lack of considering an extension of continuous tunnels and soundproof tunnels. For these reasons, it was judged that an amendment to the law would be necessary. Therefore, this paper reviewed the changes in domestic laws related to the disaster prevention facilities of road tunnels, and the results of the study on the parts that need to be revised in the fire-related laws through a comparative analysis between laws are as follows. First, consecutive tunnels should consider the sum of the extensions of the individual tunnels and ensure that the soundproof tunnels are included in the category of tunnels in the law. In this way, the necessary disaster prevention facilities should be installed. Second, it is necessary to secure a legal justification for installing disaster prevention facilities in tunnels. Therefore, it is essential that water mist fire extinguishing system facilities, emergency broadcasting facilities, and leading lights, which are excluded from installation in tunnels, are specified in the Fire-related laws. Third, to specify in the law that air respirators must be provided in the tunnel is necessary from the viewpoint of the field response. Accordingly, it will make a great contribution to the fire-fighting activities and the life-saving efforts by fire-fighters.
