  • Heat release characteristics of live fire load are an important parameter for performance oriented fire safety design of a building. While investigations have been carried out on the fire load and its burning behavior in office, residential and commercial buildings and so on, little effort has been paid for the rational treatment of fire load in post office buildings in Japan. In this report, burning behavior of typical combustible objects in post office buildings are studied by measuring heat release rates of plastic palettes with and without postal envelopes or packages and special containers loading numbers of palettes. The test results suggest that dynamic heat release rate is highly dependent on the condition of palettes especially if they load appropriate amount of postal envelopes or not.

  • The effects of changes in area and location of fire source, fire growth rate, and volume of compartment on the major fire characteristics, including heat release rate, in closed compartment fires were examined. To this end, a fire simulation using Fire Dynamics Simulator (FDS) was performed for ISO 9705 room with a closed opening. As main result, it was found that the changes in the area and location of fire source did not significantly affect the thermal and chemical characteristics inside the compartment, such as maximum heat release rate, total heat release, maximum temperature at upper layeras well as species concentrations. However, increasinthe fire growth rate and volume of compartment resulted in increase of the maximum heat release rate and total heat release, decrease in the limiting oxygen concentration and increase in the maximum CO concentration. Finally, a methodology for the application of fire growth curves to closed compartment fires was proposed by deriving the correlation of the maximum heat release rate expressed as a function of the fire growth rate and the volume ratio of compartment based on the ISO 9705 room.

  • Objectives : The aim of this study was to examine if there is a significant correlation between the changes of Fire- and Heat- related symptoms and motor function recovery in acute cerebral infarction patients. Methods : We studied inpatients within a month after the onset of cerebral infarction who were admitted at Kyunghee University Medical Center from May 2011 to January 2013. We executed correlation analysis between Fire-heat pattern score and motricity index score at visit 1 and visit 2, and checked if there was a significant correlation between the changes of Fire-heat pattern score and changes of motricity index score. Also, we compared the changes of both scores in patients taking Fire-heat and non Fire-heat pattern prescriptions. Results : There was a significant correlation between the Fire-heat pattern score and Motricity index score at visit 1 and visit 2, and changes of Fire-heat pattern score showed significant correlation with changes of motricity index score. Patients taking Fire-heat pattern prescriptions showed significant change in Fire-heat pattern score after herb-medication treatment while patients taking non-Fire-heat prescriptions showed insignificant change in Fire-heat pattern score. Conclusions : This study provides evidence that taking a Fire-heat pattern prescription could be considered as a first line herb-medication treatment in acute cerebral infarction patients.

  • This study aims to examine the risk of electrical fire in places where electric heat wires are used. In general, the use of electric heating wires is becoming more common and prevalent in a bid to prevent increasing damage caused by freezing and bursting in residential water pipes, factory pipes and irrigation pipes in vinyl greenhouse and a variety of heat wire products are available in market with legal safety requirements imposed on them. However, the widespread use of anti-freezing burst heat wire products has caused increasing incidents of fire, which often fail to be incorporated into statistics due to quick onsite extinguishing and insignificant damage although damage is gradually on the rise. Against this backdrop, this study aims to look into the possibility of ignition caused by electric heat wires and the mechanism of how it turns into catching fire through overheat and short circuit tests for anti-freezing burst electrical heat wires (hereinafter called the 'heat wire') and expects to serve as the basis for further observations and analyses on the cause of fire and the process of ignition in a scientific manner.

  • Although fires caused by heat generation due to Cu2O breeding in wire connections are well-known among fire investigators, there are few papers on the analysis and introduction of fire cases by heat generation due to Cu2O breeding. This study analyzed fire statistics caused by heat generation in electrical connections and the phenomena and features of heat generation due to Cu2O breeding. Then, a fire which occurred in the wire connection in a university lab by heat generation due to Cu2O breeding was analyzed in more detail. This fire case could reach a conclusion that heat generation due to Cu2O breeding caused a fire in the wire connection through the fire pattern investigation of fire origin, the visual investigation of wire connection, 3D CT, power-on-test, and stereoscopic microscopy, SEM and EDS analysis.

  • The present study performs a series of 40 % reduced scale of ISO-9705 fire test to investigate the characteristics of heat flux on the floor level in terms of fire characteristics and location in the compartment. The heat flux was measured with Schmidt-Boelter type heat flux gauge at two locations on the floor level of inside and doorway side of the compartment. Different types of fuel - methane, heptane, toluene, ethanol, polystyrene - were burned in this test series. The measured heat flux inside of the compartment was relatively higher than that of front side as the heat release rate of fire and upper layer temperature increased. The difference of measured heat flux at inside and doorway side increased for high sooty fire. The present study shows that the heat flux distribution at lower layer greatly depend on the thermal radiation from fire and upper layer, not only the upper layer temperature but also various fire characteristics such as composition of combustion gases, soot concentration, ventilation condition and so on.

  • The purpose of this study was to evaluate the diagnostic indicators which are used for the identification of fire-heat pattern in stroke patients. For evaluation of diagnostic indicator, we analyzed the indicators which are composed of symptoms and signs collected from stroke patients based on the clinical records using case report form (CRF). Patients had a first-ever stroke within 1 month after the onset of stroke. Pattern identification was performed and decided by two independent physicians. Two patient groups that consist of fire-heat pattern and the other patterns were compared to isolate important indicators affecting the fire-heat pattern identification of stroke patients. The 8 indicators among 16 fire-heat pattern indicators were significantly more frequent compared with non fire-heat pattern group. Logistic regression analysis revealed that 5 indicators among fire-heat indicators were significantly sensitive indicators being capable of identification of fire-heat pattern. But two of them was from the indicators of dampness-phlegm pattern and yin deficiency pattern. Therefore, further studies are required for the development of Korean standard indicators of Fire-heat pattern identification.

  • In this study, experiment and numerical analysis were conducted to identify the heat transfer characteristics and behavior of high-strength concrete upon a fire. The numerical analysis was employed to forecast the characteristics and properties of the high-strength concrete upon a fire, which can not be accomplished through a fire test due to the specific conditions and restrictions associated with the test. The result of the numerical analysis was compared with that of the test to verify the reliability of the analysis. In the numerical analysis of the heat transfer characteristics and behavior of 80 and 100 MPa high-strength concrete upon a fire, the commercial software of ABAQUS(V.6.8) was used. It was observed from the experiment that the contraction of the concrete with fiber-cocktail was mitigated by 25~55 % compared with that without fiber-cocktail because the fiber controlled the heat transfer of the concrete and thus improved the fire-resistance performance of the column.
