This study is a descriptive study which was done to examine the circumstances surrounding burn accidents in children in order to develop a burn prevention program. The subjects for the study were the mothers of 107 children admitted to two burn specialty hospitals in seoul and the mothers of 172 healthy children attending day care or kindergarten. The tool used in the study was developed by the researchers, pretested and refined. Cronbach's alpha was 0.72. Data collection was done between November 1995 and April 1996. Statistically analysis was done using SAS Version 6.04 and the data was analyzed using test, chi square, regression and logistic analysis. A suumary of the results shows the following : Eighty percent of the children in both groups lived in nuclear families but comparatively more of the children with burn accidents lived in apartments. More of the parents in the group of healthy children had university education and held white collar or professional jobs, while the parents of the children with burn accidents were slightly younger than the parents of the healthy children. but not significantly younger. A significantly greater number of families of children with burn accidents had more than one child and the characteristics of the children with burn accidents that they were more frequently boys, either first or last born and very active. Most of the burn accidents occurred in fall or winter. sometime between noon and midnight and the majority occurred in the home and were caused by hot liquid. In 86% of the cases emergency care was not given at home but the child was brought to the hospital emergency unit. Most of the burns were second degree or greater. involved the arms or legs. required admission, and 41.5% occurred when the parents were preparing or eating meals. In a test of knowledge of preventive measures, the mothers of children who had suffered burn accidents scored slightly higher than the mothers who had no experience with burn accidents, but this was not statistically significant. As to what to do in the case of a fire, the mothers of the healthy children had more knowledge about who to notify. but 70% of the mothers in both groups did not know how to escape from the house if it was of fire. 80 to 96% did not know what do to in case of a fire, such as rolling if clothes were on fire. 80% did not know what emergency care to give for a burn, and 74 to 87% did not know when it is appropriate to try to put out a fire. It can be concluded from this study that. since the results show that the most frequent situation which resulted in burn accidents was when the parents were not aware of the danger of burns or were not paying attention to the child. and when there were no protective devices to prevent burns. and that accidents most frequently occurred at home. the most effective way of preventing accidents is to develop in the parents a "safety mind", Since burn accidents in children are usually more severe than in adults. the physical. emotional. psychological and social damage is greater. In order to develop and awareness of this in the general public. the use of mass media. books and pamphlets and other educational media that provide education on prevention of burn accidents need to be utilized.

The research investigates the identification of necessary geographic information needed by forest fire suppression helicopter pilots, and the ways to acquire the required information from public institutions. Firefighting helicopter pilots demand 7 physical geographic and 13 human geographic data. Applying the geographical information acquired from Korean public institutions, the following 15 characteristics (3 physical geographic, 12 human geographic) can be found: altitude and highlands, river, high population and urban areas, roads, national park and state boundaries, fuel re-supply facilities, freshwater areas, cultural assets, (LPG)gas charging stations, gas stations, ammunition storage areas, ground power cables, and steel towers. Within the database of physical geography, there is a need for improvement on bird habitat details. Also, the availability of visibility, wind directions, and wind velocity data is limited and therefore requires refining. The location of refueling areas can be obtained by applying information received from institutions to the GIS spatial analysis.

This paper introduces a numerical model which can evaluate the fire-resistant capacity of reinforced concrete members. On the basis of the transient heat transfer considering the heat conduction, convection and radiation, time-dependent temperature distribution across a section is determined. A layered fiber section method is adopted to consider non-linear material properties depending on the temperature and varying with the position of a fiber. Furthermore, effects of non-mechanical strains of each fiber like thermal expansion, transient strain and creep strain are reflected on the non-linear structural analysis to take into account the extreme temperature variation induced by the fire. Analysis results by the numerical model are compared with experimental data from the standard fire tests to validate an exactness of the introduced numerical model. Also, time-dependent changes in the resisting capacities of reinforced concrete members exposed to fire are investigated through the analyses and, the resisting capacities evaluated are compared with those determined by the design code.

Satellite data play a major role in supporting knowledge about forest fire by delivering rapid information to map areas damaged. This study, we used 7 Sentinel-2A images to detect change area in forests of Sokcho on April 4, 2019. The process of classify forest fire severity used 7 levels from Sentinel-2A dNBR(differenced Normalized Burn Ratio). In the process of classifying forest fire damage areas, the study selected three areas with high regrowth of vegetation level and conducted a detailed spatial analysis of the areas concerned. The results of dNBR analysis, regrowth of coniferous forest was greater than broad-leaf forest, but NDVI showed the lowest level of vegetation. This is the error of dNBR classification of dNBR. The results of dNBR time series, an area of forest fire damage decreased to a large extent between April 20th and May 3rd. This is an example of the regrowth by developing rare-plants and recovering broad-leaf plants vegetation. The results showed that change area was detected through the change detection of danage area by forest category and the classification errors of the coniferous forest were reached through the comparison of NDVI and dNBR. Therefore, the need to improve the precision Korean forest fire damage rating table accompanied by field investigations was suggested during the image classification process through dNBR.

This research is designed for Disaster Mangement Information System(DMIS) which is essential to management of disaster. Management of disaster is not only social problem but also official policy. To perform the research, we examined the necessities, characteristics, and problems of DMIS, analyzed the actual conditions of DMIS in operation, and reviewed relevant documents. To investigate the actual conditions of using DMIS, we analyzed degrees of cognition, channels of cognition, ratio of application, the reason why people do not use DMIS, and the fields suitable for applications of DMIS. And, to evaluate DMIS, we performed regression analysis. In that analysis, we set utility, accessibility, quickness, compatibility, and public ownership of information as independent variabls, and we set overall estimation as dependent variable. Objectives of this research are to understand the actual conditions of DMIS in operation, to evaluate the DMIS from the viewpoint of fire officers, to reveal the problems of DMIS, and to present better ways for using DMIS from its own problems. For analysis of data, we used frequency analysis, T-test, correlation analysis, and regression analysis. From the results of the research, we advised that better application of DIMS requires Standardization and compatibility of DIMS, public ownership of information, use of IT(Information Technology) like mobile information system, management and analysis of disaster information, maintainment of personnel specialized in information part, and necessities for education and training.

Purpose: Firefighters were subjected to be exposed to 24-hour shiftwork and high level of job stress, but there is little study of fire fighters about between Job Stress and Psychological stress in Korea. This study was performed to evaluate job stress of fire fighters grouped by different job types and analyze the health effect of job stress by using a PWI-SF(Psycho-social Well-being Index, Short Form). Methods : This study was to measure the degree of job stress and socio-psychological stress of firefighters working at 119 safety center and analyze the relationship between job stress and mental health, through self-administered questionnaire survey on 918 fire fighters working at fire department located in Korea, during October in 2008. Question items of the questionnaire consist of general characteristics, job stress, and socio-psychological stress. Job Stress Measurement Scale for Koreans was used to measure job stress, while PWI-SF used for socio-psychological stress. Collected data was analyzed through frequency analysis, ${\chi}^2$ test, one-way ANOVA, correlation analysis, multi-regression analysis using a statistic program, SPSS/10.0 Ver for Windows, and statistical significance level was 0.05. Result : Accordingly, this paper is written for the purpose of scrutinizing the reason of 119 rescuers' job stress and Socio-Psychological stress. This thesis tries to analyze a problem and provide contents through many variables concerned and theoretical investigation with the actual research of questionnaire. The results of the study are summarized as follows : Fire fighters feel relatively high stressful in their performance. Job stress, organizational commitment and burnout did not have been influence upon by individual cases such as economic condition, regular exercise etc. Finally, as a result of step by step regression analysis, the variable that can explain Socio-Psychological stress the best was negative emotion scale(NE). Conclusions : It is necessary to conduct repeated studies in the future, since the study implied that there was a contrary relationship between job stress and socio-psychological stress. In order to reduce job stress and maintain better mental health, it is more important than anything else to help firefighters have willingness and efforts to sustain a healthy life, so the development of various programs and education to raise their awareness should be implemented.

A fire risk assessment in rack-type warehouse is typically determined based on the following factors: 1. flammability and fire loads for storage of goods, packing materials, and pallet, 2. a ceiling height of warehouse indoor spaces, and 3. height, arrangement, and spacing for storage racks. For appropriately extinguishing and protecting the fire in warehouses, therefore, it is necessary to classify combustibles considering the previously mentioned factors and to develop design Standards for sprinkler system. As the first step to apply automatic sprinkler system to domestic warehouses, this study investigated characteristics for commodity distribution and warehouse configuration using 28 warehouses in five distribution complexes located in Gyeonggi-do, South Korea. In addition, this study analyzed Standards for commodity distribution adopted in USA, Europe, and Japan. Using the field survey analysis, this study was aimed to provide baseline data to prepare for Commodity Classification Standard for warehouses in South Korea.

These days, the research of a sensor data management system for USN based real-time monitoring application is active thanks to the development and diffusion of sensor technology. The sensor data is rapidly changeable, continuous and massive row level data. However, end user is only interested in high level data. So, it is essential to effectively process the row level data which is changeable, continuous and massive. In this paper, we propose a sensor data management system with multi-analytical query function using OLAP and anomaly detection function using learning based classifier. In the experimental section, we show that our system is valid through the some experimental scenarios. For the this, we use a sensor data generator implemented by ourselves.

Buried pipe system is subject to leak or rupture due to internal and external defects with age. Especially, if the pipeline is designed for pressurized gas, the leak can wreak a devastating on its surrounding area. The current method of setting up underground gas pipeline is based on OGP criteria of applying one tenth of the inner pipe pressure. The criteria is applied irrespective of their burial depth or pipe's properties. At times, even the whole safety measures are totally ignored. Considering the magnitude of possible damage from a gas leakage, a precise analytical tool for the risk assessment is urgently needed. The study was conducted to assess possible scenarios of gas accidents and to develop a computer model to minimize the damage. The data from ETA was analyzed intensively, and the model was developed. The model is capable of predicting jet fire influence area with comprehensive input parameters, such as burial depth. The model was calibrated and verified by the historic accident data from Edison Township, New Jersey, the United States. The statistical model was also developed to compare the results of the model in this study and the existing OGP model. They were in good agreement with respect to damage predictions, such as radiation heat coming from 10 meters away from the heat source of gas flame.
