A Study for the Necessity of Restructuring Korea's Emergency Management Organization - Focused on Disaster.Emergency Preparation and Civil Defence Affairs -
Kim, Kook-Rae ;
Fire Science and Engineering, volume 22, issue 2, 2008, Pages 1~8
With a purpose to set up an efficient national security system for both at war-time and peace-time, President Lee's government transferred the emergency management function from the Office of Prime Minister to Ministry of Public Administration and Security (MOPAS). As a result national emergency management system has been changed into diversified management system ; the function of comprehensive disaster control, emergency preparation to MOPAS, fire, civil defense and disaster management to NEMA and anti-terrorism to NIS, which produce another inefficiency. For this reason, this research presents desirable improvement alternatives through scrutinizing current governmental function and structure.

Kim, Jin-Dong ;
Fire Science and Engineering, volume 22, issue 2, 2008, Pages 9~19
Recently the systematic change in the fire and disaster prevention administration, which was less studied than other administrative systems, has been in progress. In particular, the fire service demands are increasing and forms are diversified. The first thing you must do is to make up the fire service power according to the fire service demands. Such an allocation results in social welfare satisfaction. The purpose of this study is to investigate the determinants of fire service force. And this study investigates that fire service demand is affected by socioeconomic factor. To do this, this study reviews fire service force, the fire service demand, socioeconomic factor and financial factor. And this study sets up four hypotheses based on the theoretical backgrounds and the past research. The statistical method used for the verification of hypotheses are multiple regression analysis and structural equitation analysis. The analysis showed that fire service demand and financial factor were positive significant variable for fire service power. But socioeconomic factor was a negative significant variable. Also the analysis showed that social factor was a positive significant variable and economic factor was a negative significant variable for fire service demand.
The Special Plan of the Traffic Accident Treatment in the Emergency Car Concerning Fire Fighting
Jeng, Gi-Sung ;
Fire Science and Engineering, volume 22, issue 2, 2008, Pages 20~29
The traffic accident of Fire engine takes place very much, compared with that of the past. The reason is that there is a lot of the increase of the demand in the fire, rescue, first aid, and the public request. Also, because the Fire engine should go out at the place of the accident very quickly, it should inevitably violate the traffic regulations. Therefore, this is due to the traffic accident. Despite the urgent situation in the infringement motive of traffic regulations, the outbreak of the traffic accident does not vary largely from the degree of the disadvantage. Accordingly, a fire officer should take charge of his social and economic disadvantage by himself. In this situation, a fire officer has no choice but to start moving passively not to be afflicted with his own disadvantage. Most of the situations concerning the fire fighting are the ones to be controlled urgently. Nevertheless, because of the disadvantage of the traffic accident, passive mobilization of the fire fighting equipment is the heavy burden of all the people of the nation. Therefore, Special institutional safety device should be ready for the protection of the life and property of all people. The special law concerning the processing in the accident of the emergency car needs to be revised. By establishing this special law, the government should not provide the officer who drives the fire engine with the disadvantage caused by traffic accident.

We have performed the inflammability test for various flooring materials through a radiant heat panel tester by using the specification KSISO 9239-1 (an examination method of flooring materials) that has been set as an international standard for the fire prevention means of interior flooring materials. We have measured the flame spread distance, critical heat flux and smoke density generated by the fire of various flooring materials while using the radiant heat panel tester. The measurement result has shown the burning characteristics different from each other by the respective flooring materials and we could see that the surface materials and construction elements influence greatly on the heat release and smoke generation. We could see that the evaluation method above is an important test method in evaluating the critical heat flux, smoke generation and flame spread distance that are Important factors in studying for fire risks and it is judged that setting and applying a fire evaluation method of flooring materials suitable for the domestic construction use would be relevant.

Fire Science and Engineering, volume 22, issue 2, 2008, Pages 38~43
Recently, the application of transverse ventilation system in accordance with oversized exhaust ports has been increased in bidirectional road tunnel in order to improving smoke exhaust ability. In this study, numerical simulations were carried out by using FDS (ver. 4.0) which includes variations of exhaust flow rates and heat release rate of fire to obtain the optimal smoke exhaust rate in case of fire in the transversely ventilation system. As a result, smoke exhaust amount tends to increase when the inner velocity is existing in the tunnel. In case of internal longitudinal air velocity 2.5m/s face to the fire, smoke moving distance should be restricted within 250m when the smoke exhaust rate which exceeds

Lim, Kyung-Bum ; Nam, Ki-Dong ; Kim, Ki-Hwan ; Park, Su-Hong ; Hwang, Myung-Hwan ;
Fire Science and Engineering, volume 22, issue 2, 2008, Pages 44~48
In this paper, we measured a contact angle, surface resistivity and XPS to study the thermal aging characteristics of the epoxy resin for cast resin transformer. As a result of this experiment, we found that the contact angle increases up to
as it causes a re-crosslinking on the surface, but starts decreasing at
as it causes heat condensation. As a result of examining the oxygen/carbon peaks through the XPS analysis, we obtained a higher oxygen peak vs. carbon in the first untreated sample, but it showed the opposite trend after heat treatment. That rise in the carbon peak continued up to
, but decreased again at the temperatures above. That's because it kept forming a stable surface structure up to
but its carbon combination got destroyed due to a rapid oxidization at
. And a conduction path was formed easily with the hydrophile property caused by rapid surface activation.

Kim, Myung-Bae ; Choi, Byung-Il ;
Fire Science and Engineering, volume 22, issue 2, 2008, Pages 49~56
Smoke propagation for the Daegu Metro fire is reproduced by a reduced-scale model experiment. The three-story station building was modeled with 1/20-scale, and the tunnel connected to the platform was not completely modeled because of its length. To include the flow resistance the tunnel provides the mesh screens were used in the model. The fire scenario was selected based on the fire growth rate of the metro car seat where the fire initiated. The time when smoke arrived at each compartment in the station building was measured by thermocouples and visualization. Regarding fire ventilation, the air supply that has been accepted as conventional design in a subway metro building intensifies smoke spread. The results show that the whole building was filled with smoke in about 10 minutes in case of no ventilation.

The characteristics of the spread of a forest fire are generally related to the attributes of combustibles, geographical features, and meteorological conditions, such as wind conditions. The most common methodology used to create a prediction model for the spread of forest fires, based on the numerical analysis of the development stages of a forest fire, is an analysis of heat energy transmission by the stage of heat transmission. When a forest fire breaks out, the analysis of the transmission velocity of heat energy is quantifiable by the spread velocity of flame movement through a physical and chemical analysis at every stage of the fire development from flame production and heat transmission to its termination. In this study, the formula used for the 1-D surface forest fire behavior prediction model, derived from a numerical analysis of the surface flame spread rate of solid combustibles, is introduced. The formula for the 1-D surface forest fire behavior prediction model is the estimated equation of the flame spread velocity, depending on the condition of wind velocity on the ground. Experimental and theoretical equations on flame duration, flame height, flame temperature, ignition temperature of surface fuels, etc., has been applied to the device of this formula. As a result of a comparison between the ROS(rate of spread) from this formula and ROSs from various equations of other models or experimental values, a trend suggesting an increasing curved line of the exponent function under 3m/s or less wind velocity condition was identified. As a result of a comparison between experimental values and numerically analyzed values for fallen pine tree leaves, the flame spread velocity reveals a prediction of an approximately 10% upward tendency under wind velocity conditions of 1 to 2m/s, and of an approximately 20% downward tendency under those of 3m/s.

Park, Jae-Sung ; Yoon, Myong-O ; Park, Jong-Tae ;
Fire Science and Engineering, volume 22, issue 2, 2008, Pages 97~103
As multiplex available premises become more complex and diversified due to increasing social and individual demands, the evacuation safety gradually deteriorates exhibiting functional difficulties even in ordinary fires. Considering the limitations of passive evacuation systems such as evacuation stairs and corridors, an evacuation facility must be designed, installed, and maintained the way that it remains fully functional and efficient when fire breaks out. This study tries to identify the issues of evacuation facilities and devise how to improve them by investigating the evacuation facility efficiencies of multiplex available premises and conducting a survey on fire safety attitude.

According to the Fire Services Act revised in 2005, it has been required to set up sprinkler systems to all floors to the newly builded apartments having above 11 floors. But, according to the Fire Services Act before 2005, it had been required to set up sprinkler systems from 16 floors to the top floors to the apartments having above 16 floors. This case is the accident that a victim was dead by the fire which is inferred as an accidental fire by a cigarette butt in a 17th floor apartment unit in an apartment having 17th floors and that the bereaved family called in question why the sprinklers non worked at the fire. Through the field investigation, we checked that the sprinklers worked well when the fire detectors at the 16th floor of the apartment were operated and that the sprinklers non worked when the fire detectors at the 17th floor of the apartment were operated. We made clear that the cause of the sprinkler non-working at the 17th floor is the programming error of the sprinkler controller.
Development of Packed Bed Lung Model for the Deposition Studies of Fire Smoke
Goo, Jae-Hark ;
Fire Science and Engineering, volume 22, issue 2, 2008, Pages 121~128
Adverse health effects of inhaled smokes are associated with the amount of the particles deposited in human lung. Lung model is needed to simulate smoke deposition because of the hardness of the in vivo deposition experiment. However, it is hard to realize the successively decreasing bifurcations in the model. In this work, an experimental lung model was developed to simulate the smoke deposition in the lung. Instead of bifurcating airways, the lung model was made of packed beds of which size decreased downwards. The experimental results using this model showed good agreements with existing results for real lung in the deposition characteristics. The model could be applied to the studies of health risk assessment of the inhaled smoke particles generated by fire.
