  • According to the statistical analysis on the electrical fire of 2005 years, most of electrical fire is generated from short circuit(4,985 cases), overcurrent(755 cases) leakage current(391 cases), poor contact(378 cases), disconnection(36 cases) on the electrical wiring device. The researches for the fire hazard about normal electric wiring have already been progressing in the advanced country such as USA and Japan, but Comparative study of the disconnection has not been conducted. Therefore, in this paper, we have simulated the thermal analysis for electrical wire according to deteriorating time in a normal state and disconnection with electrical wire using the electrical-thermal finite element method(Flux 3D). This paper acquire basis data of electricity fire signal by disconnection and wish to help for electrical fire cause diagnosis business.

  • Because of not accepted on escape using elevators in fire emergency has some background. In the background elevator hoistway has turn into smoke spread route in fire. The escape that used an elevator was not able to make ends meet; of the big confusion is expected that cannot control the escape adequately, and do that elevator facilities breakdown possibility by the fire water, the escaper shut in car. Therefore ban on elevator service in fire time as a general rule. Recently, a few company promote super high-rise architecture in the country, a fire disaster prevention and human life safety measures preparation for PBD(A Performance Based Fire Protection Design) are studied concretely. And there is the escape example in fire time that used an elevator in the foreign country. You must promote it so that the escape measures that used enclosed stairway and an elevator in charge of a function of the mutual supplement. The result of this research can be used for establishing the standard and regulation for using elevators in fire emergency.

  • In Japan, there are over the 100's fires in the social welfare organs every years. People are interested in fire protection who live in an institution for the aged or weak person's places and worried about it. I surveyed the social welfare organs were safety from fire to firewarden who worked at an institution for the aged in Tokyo. In the paper, I asked how do you think about the fire safety problems and condition of the facilities. And base on firewarden's view, I reviewed(examined) the fire prevention measures, each facility's problems and how to improve the fire protection.

  • There is a need to analyze various factors in evacuation safety assessment of building in fire. In the current performance based design, evacuation safety assessment in case of fire is being conducted through the simulation as FDS and Pathfinder. However, the location and size of the door, the location of evacuation in the event of a fire are not considered when design. Accordingly, it is difficult to determine the worst case scenario considering the actual fire. Therefore in this study, in this study, we will propose an appropriate evaluation plan through simulation considering the worst-case scenario that may occur in case of fire.

  • The aim of this study was to reduce the number of negligent accidents by improving the fire safety consciousness of infant and child teachers working in a day care center. For this purpose, 242 early childhood teachers working in the national nursery school in Daejeon and Chungcheongnam-do were surveyed. For the survey, the questionnaire consisted of job satisfaction, teacher's efficacy, and fire safety consciousness. The survey data were analyzed using the SPSS 20.0 win program. The factor of job satisfaction and teacher's efficacy had a significant positive influence on the fire safety consciousness of the early childhood teachers (<.05). The teacher's efficacy was found to mediate the relationship between the job satisfaction and fire safety consciousness. In conclusion, this study suggests that teacher's fire safety consciousness is high when the teacher's job satisfaction and efficacy are high. This study is expected to contribute to basic research to increase the teachers' consciousness of fire safety.

  • Recently, the fire risk of architectural structures is increasing due to the super high - rise and super - size of the buildings. Therefore, the direction of fire safety design tends to change from the existing design to the performance - based design. In particular, domestic fire safety policies are divided into building law and fire fighting law. In case of fire fighting law, performance design is already carried out. Therefore, this study summarizes the prediction formula for fire characteristics among the structural fireproofing design field as shown in Fig. 1 according to this situation, and compares it with the standard method of each country in particular.

  • One of the most serious national problems is the shortage of houses, especially in great cities. Housing shortage resulted from an overpopulated city brought the high-rise apartment buildings. While these buildings provide city-dwellers with much more houses, they have the basic fire safety problem in proportion to their heights. In these respect, this study aims to present the basic data for the fire safety design of high-rise apartment buildings. In this study, national fire damage statistics of past eleven years were investigated and the problem of the fire safety design of high-rise apartment buildings was studied through the methods of questions, observations and records on the representative six high-rise apartment buildings in seoul.

  • Performance based design is a recent evolutionary step in the process of designing fire protection systems. In essence, it is a logical design process resulting in a solution that achieves a specified performance. Sometimes the prescriptive solutions presented in various codes and standards are too expensive or inflexible. Often the solutions do not and enables optimization of a solution for cost and function. In this study, performance based design was carried out to determine the extent of passive fire protection for oil terminal facilities. The results of performance based design were compared with those of prescriptive code based design. Performance based design is not always more economic than prescriptive code based design but provides more reliable and effective design that is fit for the purpose.
