Recently, damage scale of human-induced disaster is sharply increased but its occurrences and damages are so uncertain that it is hard to construct a resonable response & mitigation plan for infrastructures. Therefore, the needs for a advanced risk management technique based on a probabilistic and stochastic risk evaluation theory is increased. In this study, these evaluation methods were investigated and a advanced disaster risk evaluation method, which is based on the probabilistic or stochastic risk assessment theory and also is a quantitative evaluation technique, was suggested. With this method, the safety changes as the result of fire damage management for recent 40 years was analyzed. And the result was compared with that of Japan. Through the consilience of the traditional risk assessment method and this method, a stochastical estimation technique for the uncertainty of future disaster's damage could support a cost-effective information for a resonable decision making on disaster mitigation.

Critical infrastructures (energy, information technology and communications, banking, transportation, public government services, etc.) are now more vital to modern society. Citizens, businesses and governments all rely on an array of interlinked physical and information infrastructures to satisfy their needs and perform their daily operations. At the same time, these infrastructures are becoming increasingly interdependent, such that failure of one of them can often propagate and result in domino effects. Recent dramatic episodes, from 9/11 to the Madrid train bombings, the April 2010 ash cloud the power cuts in Korea in 2011, and the cyber-attacks have highlighted the need for a comprehensive, internationally coordinated policy for the protection of critical infrastructures. For the purposes of this report, we define critical infrastructure as infrastructure whose failure would result in substantial damage to society and/or the economy.

In this study, we have investigated the combustibility of five shrubs growing in Youngdong area such as Lindera obtusiloba, Lespedeza maximowiczii, Zanthoxylum piperitum, Zanthoxylum schinifolium, and Corylus heterophylla var. thunbergii using the ignition temperature tester, the cone calorimeter and the smoke density chamber in order to estimate the danger of a forest fire. The results showed that Lespedeza maximowiczii has the lowest ignition temperature, the fastest ignition time and the highest average release concentrations of CO and $CO_2$. Zanthoxylum piperitum and Zanthoxylum schinifolium showed the highest level in heat release and smoke release, respectively. Therefore, we have concluded that Lespedeza maximowiczii has the highest ignitibility, Zanthoxylum piperitum the most intensive fire spread and fire intensity, and Zanthoxylum schinifolium and Lespedeza maximowiczii most difficult to escape from a forest fire.

To improve fire-resistance of a high strength concrete against spalling under elevated temperature, fibers can be mixed to provide flow paths of evaporated water to the surface of concrete when heated. In this study, the experiment of a column under fire and mechanical loads is conducted and the material model for predicting temperature of reinforcement steel bar and mechanical behavior of fiber-mixed high strength concrete is suggested. The material model in previous studies is modified by incorporating physical behavior of internal concrete and thermal characteristics of concrete at the elevated temperature. Thermo-mechanical analysis of the fiber-mixed high strength concrete column is conducted using the calibrated material model. The performance of the proposed material model is confirmed by comparing thermo-mechanical analysis results with the experiment of a column under fire and mechanical loads.

Based on major safety-related statistics of cities, provinces, counties, and districts across the country, social disasters manage regional safety index ratings in six areas(traffic accidents, fires, crime, life safety, suicide, and infectious diseases), and natural disasters operate a management system. The current application of the regional safety assessment of natural disasters is very insufficient to evaluate the local risk of natural disasters up to the Eup, Myeon, and Dong level, and it is marked too engineering and difficult for the general public to use. The purpose of this study is to present Korea's natural disaster local risk assessment as an improvement model that extends to the sub-unit of Eup, Myeon, and Dong, using the local risk assessment model mixed with natural and social disasters.

It is natural that The government should be responsibility for the fulfillment of obligation to prevent a notional life, accurate rescue and first-aid from various calamities. Although, The government policy is established a foundation that is reventing a national life and a property from the calamity with deciding of the fire line, that is not satisfied with taking precautions against a calamity. In case of the calamity there is always pointed the confrontation procedures, especially, In case of crisis The government is lacking to come to an developed country on account of system of the emergency rescue and first-aid. The prevention and provision are the most important thing with reference to a confrontation of the calamity. But calamity is happened without warning, so We should establish line of prompt rescue and first-aid lately that is very important thing. The First, We should get the single line of the rescue and first-aid through a integration and elimination in terms of a law of the emergency rescue and first-aid, but also we strengthen a line of a scene confrontation ability and speciality. To raise awareness of improving a rescue and ability of first-aid, through reinforcing the human and material equipment of The 119 rescue party to charge of emergency rescue and first-aid in effect.

The major aim of this study was to provide information on the chemical accidents that occurred involving chemical substance transporting accidents from 2013 to July - 2016. The total incidence of chemical transporting accidents was 77 cases; 74 cases occurred by the spill & leakage type. The main cause of the accidents analyzed was traffic accidents (41 cases). Forty-six accidents were related to hazardous chemical substances. Among the 46 hazardous chemical substances involved in transporting chemical accidents, 46% of the accident substances were hydrogen chloride. For the prevention and response to accidents occurring during the transportation of chemicals, it is necessary to complement the precautions for chemical accidents caused by transportation accidents and chemical spills and leaks of chemicals. In addition, when the chemical transport of an accident occurs, it is necessary to apply a chemical transport safety system for chemical transfer.

In order to analyze causes and results of job stress among fire fighters, the structural model was developed and reviewed by a survey asking questions about job stress, job commitment role confusion and relationships with co-workers to 961 fire fighters working in Seoul, Korea. Results of research are correspond with previous research results done in different working environment although fire lighters experienced much higher job stress than average public officers. According to research results, both' job character' and 'relationships with co-worker' influenced 'job stress' and 'job commitment' directly at a statistically significant level. 'Role confusion' influenced 'job stress' directly but influenced 'job commitment' indirectly through 'job stress'. Results of this research could be utilized for expressing necessity of building a job stress management system for fire fighters in Korea.

This study is to investigate the problems of procurement circumstance of the current fire service funds and to suggest the alternatives for procuring the fire service funds for dealing with increasing demand on the fire service in the local autonomous era. The results are as the followings. First, most fire service officers see the procurement circumstances as premature stage and perceive the necessity of the improvement of this condition. In particular, the officers at the fire center recognize this problem as an urgent question than the officers at the front fire branches. In addition, as for the alternatives of the procurement of fire service funds, both groups prefer the long term plan to the short term plan, and show positive responses to the National Emergency Management Agency and central government as the entity to raise fire funds. As for the alternatives to improve financial system, both groups show the most positive responses on the way to increase the current common facilities tax. As for the specific procurement alternatives of fire funds, both groups agree the alternative to increase common facilities tax mostly, and to the next they agree the alternative to insecure fire funds by restructuring current financial system and by establishing fire service hospital and fire equipment maintenance center.
