This study is based on the principle of solar power system and fire breakout. The result of the survey indicates that a solar power system is vulnerable to fire due to lack of maintenance after the installation. Currently the national fire safety agency does not have standards and legal provisions for the installation and maintenance of solar power facilities. Therefore, it increases the risk of fire breakouts as well as possibility of electric shock for the firefighters during fire fighting. This results possible damages to the human and equipments. In this study is proposing an automatic fire extinguishing system to reduce the power generation of solar panels during fire breakouts. Also, propose an over load current alarm system and fire prevention measures for fire fighters. The results of this study will be used as basic data for further fire testing of solar power systems.

Many severe earthquakes have occurred along the main fault lines in the world. In recent years, there has been a high incidence of small- and large-scale earthquakes in our country. These occurrences of earthquakes have become increasingly serious, owing to a degrading earth environment. An earthquake, in general, causes far more serious damages like disruptions in electricity or gas facilities, and fire disasters from its annexed effects than by its vibrations or the shock itself. In this paper, we present a countermeasure and its necessity in safeguarding against fire disasters in regional heritage villages such as "Asan Oeam," "Jeonju Hanok," and "Andong Hahoe." A more systematic and effective strategy for prevention systems against severe fire disasters is proposed after performing various related investigations and analyses of existing domestic and international systems. We investigated the existing fire security systems and their historical records with the tendency of earthquake occurrences in these three folk villages. In this proposal, we present a strategic approach for safeguarding against fire damages in our regional heritage villages derived from ICT (information communication technology)-based DPD (disaster prevention design), after examining the laws and regulations of fire-prevention strategies in Japan, America, and Europe.

The objectives of this study is analysis of the characteristics of fire risk and survey of narrow dwelling space(the Karaoke, Gosiwon etc). The narrow dwelling space has special structure characteristics; the narrow and the complex escape rote. Gosiwon have very separate and exclusive space room, so have the problem a suppression of fire. Furthermore almost Karaokes located in basement have a complex and limitary escape rote. Therefore we should research and development the exploration equipment that search a source of the fire and a emergency rescuer in the scene of the fire.

This study examines the physical characteristics of self-regulating heating cables caused by increased temperature and fire risk due to local degradation. A thermo hygrostat system, a convection dryer, a digital multimeter (Agilent 34465 A), NI DAQ, and the LabVIEW program were used to assess the physical properties in response to temperature fluctuations. As the temperature increases, the resistance of the self-regulating heating cable increases; however, when the critical point is exceeded, the resistance sharply decreases. A problem arises when the resistance value cannot return to its original state even though the temperature is lowered to the initial state. Moreover, when the ambient temperature rises while power is applied, the resistance value initially increases, and the flowing current decreases, maintaining a constant state. However, when the critical temperature is exceeded, the flowing current increases because of a rapid decrease in the resistance value, progressing to ignition. When the resistance value decreases because of the deterioration of one local area, the total resistance value becomes less than the initial resistance value. Therefore, the flowing current increases and an ignition problem occurs at one location where deterioration occurs. Despite the sustained flames and arcs resulting from the changes in the overall physical properties of the self-regulating heating cable and resistance variations due to local decline, the fire continued as the flowing current was lower than the operating current of the circuit breaker, failing to cut the power. In the case of self-regulating heating cables and heating wires, which are the leading causes of fires in winter, efforts are needed to ensure the need for periodic maintenance and the use of KS-certified products.

In the area of disaster management, we have more focused on the rapid response and recovery, but preventive approach for disaster is becoming more and more important. For mitigation of disasters, we need to analyze the vulnerable area according to each disaster, and need to manage those area systematically. In this research, we selected the fire as a type of disaster, developed guideline of construction of vulnerability map of fire, and built the vulnerability map of fire in Changshin-Dong, Jongro-Gu, Seoul as a case study area. The vulnerability map of fire can be applied to grasp the vulnerable area in advance and manage it systematically. In addition, it can also be applied in the landuse planning and the rearrangement of infrastructure for the mitigation of disaster when we build detail city planning.

This study examined the role of volunteer fire fighters in coping with great disasters in terms of community-based disaster management to provide some implications from a qualitative comparative case study between Korea and Japan. Kobe, which suffered from the Great Hanshin-Awaji earthquake in 1995, was the study area. The city experienced an inadequate institutional system and lack of disaster management infrastructure at the time before the disaster. The study indicates that Korea volunteer fire fighters are not prepared sufficiently to tackle great disasters in terms of the supporting system, capacity and role by analyzing improvement plans of Japanese Volunteer Fire Fighters after Great East Japan earthquake in 2011. The results of the case study suggests improvements in the disaster management system to provide cooperation between the central government and local government, core task distribution, and community-based disaster management.

According to the analysis of the patient transport in the fire disaster occuring at Taegu Subway Jungangro Station February 18th, 2003, authors concluded as follows. Patients were transported mainly to medical institutes which were larger and that had shorter distance. Because of non-emergenct patient's transport to larger and nearer institutes, some critical patients should be transported to more distant institutes. Dead patients before arrival were transported relatively evenly. An adequate transport according to adequate triage should be performed in the future. Early mitigation and response, correlation with the method of transport, regional guide line of disaster transport and correlation between disaster information and emergency medical information should be corrected and need research in the future.
