This Study is to analyze the characteristics of arson fire under fire dynamics to protect people and property from arson fire which has been radically increased with the development of the Korean economy. Assembly and merchandise purposes such as theater, retail, and exhibition has been performed as the arson fire study. The experiment for this study is based on the analysis of the characteristic for its own combustion process and smoke spread when arson fire occurs. This study presents the analysis through comparing the condition of setting fire using liquid fuel such as thinner on purpose to the condition of setting fire naturally depending on each occupancy.

Fire industry has been an important role in from the fire and disaster to protect life and property of citizens. In recent years the national fire industry in Japan and the United States Fire industrialized countries with respect to the fire industry in quality and technology challenges facing the competition, and fire Industry for China and other poor countries and vulnerable to the price competition in the fire industry's difficulties with this study is necessary. The purpose of this study was to analyze the characteristics of the fire industry, the development is aimed to provide direction. The proposed development direction for the future industrial development of the fire, setting goals, fostering the promotion of industrial development direction, running through the fire in the actual application will be available.

The aim of this study is to provide the basic data of spray setting method for the fireproof covering. For this purpose, the purpose, the behavior of different three kinds method which is the number of thimes, interval, finishing for a required performance. The result of the data analysis shows that it is better to spray setting method at a time and to finish by natural becomes to reduce a period and labor cost for works.

For life safety design of shopping mall, we selected a shopping mall, and calculated the evacuation time of means of egress. It is calculated by two kind of evacuation method. One is the computer simulation model, EXODUS. The other is Japan's method. Study way is a model structure study, selecting real shopping mall and setting scenario, calculating the evacuating time. result of study, evaluation time is very high. Therefore we confirmed that the building of means of egress is not fit to evacuation more the capacity of setting population.

The purpose of this study is to analyse the characteristics and spreading laws of parameters such as fire smoke, concentration of CO, visibility, and temperature at fire scene in high-rise residential buildings under the different conditions of fire doors and automatic fire extinguishing systems. Using Pyrosim to simulate diverse fire scenes in a high-rise apartment with corridors, to analyze the changes in those parameters. The results show that when a fire occurs, closing the fire-fighting corridor will increase the smoke temperature and concentration of CO in the stairwell, and reduce the height and visibility of the smoke layer; the automatic fire extinguishing system effectively suppresses the increase in the temperature of the fire smoke and the sedimentation of the smoke layer. Reasonable setting and operation of the automatic fire extinguishing system could effectively inhibit the spread of fire. Although closing fire corridor can slow down the direct upward spread of smoke through the corridor, it will force the fire smoke into the stairwell, which will seriously affect evacuation through the stairs. Therefore, in order to reduce risks, it is forbidden to close the fire doors of the firefighting corridor and stacking combustible materials in the corridor, Also, intensifying inspections and ensuring the normal operation of the automatic fire extinguishing system are indispensable. Based on the research results, the significance of installing fire-fighting facilities in the construction of high-rise apartments was discussed and proved.

Normally, the degradation of concrete member exposed to fire is largely dependent on the fire scale and fire condition. With all ensuring the fire resistance structure as a method of setting the required cover thickness to fire, the RC is significantly affected from the standpoint of its structural stability that the compressive strength and elastic modulus is reduced by fire. Thus, this study is concerned with experimentally investigating fire resistance of high strength-light weight concrete. From the test result, high strength-light weight concrete is happened explosive spalling. The decrease of cross section caused by explosive spalling made sharp increasing gradient of inner temperature.

This study was intended to conduct a Real-scale fire test to predict the fire behavior by unit space at the apartment building where a huge casualties and injuries are likely. After setting the inflammables inside the house, the test aimed to identify the fire characteristics to each unit item was carried out. The house was divided into 4 unit space such as kitchen, living room, bedroom and a study for a real scale fire test. As a result, bedroom reached to flashover state in 5minutes after setting the fire, indicating a rapid fire growth such as 7433.3kW of maximum thermal emissivity, 578.6ppm of carbon monoxide, 1.25ppm of carbon dioxide and $1,350^{\circ}C$ of maximum indoor temperature. Particularly, the fire growth was made up to critical temperature which might cause a severe damage to the people within 3minutes, if the fire were not extinguished at inflammable space at the early stage of fire, which stressed the need of early response. The result of a real scale fire test could be compared with the outcome of expanded simulation test and used in predicting the fire spread at the space for different use.

This paper present the way the fire detector determines whether a fire has broken out or not using the fuzzy measure. This method is based on Dempster's combination rule using the belief measure. The detector indicate a 'Fire'(F) or 'Nonfire'(N) when it determines whether a fire has broken out or not. To determine this, the fuzzy rule is applied in the setting value for the heat and smoke detector which is used. As a result, It is proved that the final decision can be determined more exactly whether a fire has broken out or not in proportion to the frequency of the fuzzy measure and the value of Bel (F).

In this study, a fire cause of setting fire to one's own car to collect the insurance is analyzed. Through a close examination of causes of this car fire, it is suggested to improve current practices and institutions: (1) A collection system of fallen vehicle parts or fire debris in the fire site should be established; (2) A system of providing fire site information in detail should be established when a police station requests National Institute of Scientific Investigation (NISI) to examine causes of vehicle fires; (3) When a burned car is suspected of arson, a fire station and a police station should maintain a mutual cooperation system; (4) Procedures of examining the causes of vehicle arson in National Institute of Scientific Investigation (NISI) should be improved; and (5) Recognition of the examination of fire causes and correlation with analysis equipment should be changed.

Fire patterns have been used to determine the origin and cause of fires in every setting imaginable. However, it is very difficult to identify fire patterns from the fire-damaged remains of a devastated structure. If someone was killed by the fire, it is possible to identify fire patterns by analyzing the concentration of carbon monoxide-hemoglobin in the body of deceased as well as the pace of the fire. For example, a low level of carbon monoxide-hemoglobin in the body of the dead indicates a rapid fire with accelerants and the death was caused by severe heat and thick toxic fumes. However, a high level of carbon monoxide-hemoglobin in the body of the dead demonstrates that the fire was slow and/or there was a flameless form of combustion. Thus, this study identifies fire patterns through analyzing the level of carbon monoxide-hemoglobin concentration on the dead from the fire.
