  • For the effective management of forest fire, understanding of regional forest fire patterns is needed. In this paper, forest fire ignition and spread characteristics were analyzed based on forest fire statistics. Fire occurrences, burned area, rate of spread, and burned area per fire between 1991 and 2007 were parameterized for the cluster analysis, which results were displayed using GIS to detect spatial patterns of forest fire. Administrative districts such as cities and counties were classified into 5 clusters by fire susceptibility. Metropolitan areas had fire characteristics that were infrequent, slow rate of spread, and small burned area. However, 4 cities and counties showing fast rate of spread, and large burned area, in the eastern regions of Taeback Mountain range, were the most susceptible areas to forest fire. The next vulnerable cities and counties were located in the West and South Coast area.

  • 본 연구에서는 초고층 건축물에서 피난을 할 때 피난자에게 작용하는 신체 조건과 수직적 이동방향에 따른 피난시간을 분석하였다. 초고층 건축물에서의 피난은 특성상 많은 계단을 통해 이동해야 하므로 피난자는 심리적 행동보다 주로 신체적 능력에 의존하는데, 이 때 피난자의 피로도는 계단수가 올라갈수록 급격히 상승하게 된다. 즉, 총 피난시간은 단순히 피난자의 평지 보행속도에 비례하여 증감할 뿐만 아니라 체력 등의 다른 신체적 영향 또한 받게 된다. 따라서 본 연구에서는 피난자의 신체조건을 고려한 피난예상시간을 산정하기 위해 필요한 조건들을 연구하고자 실물 실험에서의 상 하향의 보행방향과 참가자들의 신체조건에 따른 피난시간을 통계적으로 분석하였다.

  • This paper proposes improvement measures of a school safety education program by analyzing the factors affecting the cognition of school safety on the school safety transfer intention and their mediating effects. In summary, the satisfaction with the contents was represented as a variable with the greatest influence on the transfer intention followed in order by satisfaction with the instructor and satisfaction with the environment. On the other hand, satisfaction with the teaching method was not significant. In addition, the general cognition on school safety education showed that it has mediating effects on the relationship between the satisfaction with the school administrator safety education and the school safety transfer intention.

  • The purpose of this study is to recognize the necessity for the management of the available materials in cases of arsons and to prevent arson gaining an understanding of the combustion characteristics of the flammable materials and combustion accelerants in arson cases. We investigated and analyzed the statistical data on arsons and selected flammable materials (wood, paper, synthetic textiles, synthetic resins), and combustion accelerants (gasoline, diesel, solvent) that are frequently used in cases of arson. We conducted a thermogravimetric analysis to assess the thermal properties of the flammable materials. Also, we conducted burning and flame spread rate tests for the purpose of comparing and analyzing the combustion characteristics of the flammable materials and combustion accelerants.

  • In order to establish an evaluation method that can quantitatively evaluate the fire safety of existing buildings in Korea, a stochastic approach is needed to consider the extent of damage in the event of actual fire, along with the operation and installation of facilities. Accordingly, as a basic study for the establishment of fire safety assessment methods for buildings, this study aims to analyze the results of safety inspection and the degree of damage caused by the operation of fire doors and fire shutters in order to derive the reliability of fire doors and fire shutters. As a result, the results of inspection of fire shutters and fire doors and the results of operation using fire statisticians are as follows. As a result of the inspection, the positive rate of fire doors was about 82% and 98% of normal operation was derived from the fire investigation.

  • Most railroad accidents are due to human errors. In particular, most of the causes of these accidents are faults of an engine driver, such as lack of signal confirmation, insecure braking, driving by guess or force of habit. This paper identifies a problem(s) by analyzing accidents for the past 10 years and also seeks a solution to train good engine drivers in order to prevent railroad accidents. In summary, what is needed are: 1) proper placement of various manpower, 2) proper training of engine drivers, 3) proper legislation for a 2-man on board system, and 4) proper reformation of personnel management.

  • This research focuses on finding the way of improving creativity in fire stations by scrutinizing the factors influencing and enhancing creativity in organizations. As environmental changes including the needs of citizens as well as the climate change are moving culminated today, fire stations should be changed appropriately to get the legitimacy of existence not to mention their own mission accomplishments. In this respect, the creativity can be expected as the main factor for fire stations' going concern. This research provided 5 hypotheses to find whether the chosen factors such as vision, learning/unlearning and positive feedback affect the creativity in fire stations. To prove hypotheses are valid, we employed survey as a method in which 155 firemen in Seoul responded, ending up with getting the result that the vision formulation and sharing, unlearning activities and positive feedback improve organizational creativity. In conclusion, this paper suggests that fire stations establish useful policies for the creativity based on these research findings.

  • Among the various cases of fire accident, gas accident which is roost essential have a lot of forms and causes. The quantity consumed of gas is increasing because of increment of gas-using families and variations of gas machinery. The quantity consumed of gas in 2007 was 35078 tons and the average rate of increasement was 9.4%. The amount of gas accident was on the peak at 1995 when 557 accidents occurred in a year. In 2007, 123 gas accidents was occurred and the average rate of diminution was 11.5%. Accidents by LP gas took 80% of the whole accident and city gas and high pressure gas took 20%. In case of LP gas, accidents were usually occurred because of lack of blocking after the removal of gas machinery and moveable butane burner. Especially, the accidents cause by carelessness of a provider is increasing. Gas accidents which generate damage of human life and property, are caused by users' carelessness, providers' carelessness, inferiority of structure and old products. In this thesis, We will classify the gas accidents. Furthermore through the classification of accidents by forms, causes and regions, this thesis going to be a reference to understand and prevent the accidents.

  • The purpose of this study was to determine if a geriatric injury would have a statistically significant relationship with the spatial safety within a specific region. To achieve the objectives of this study, an independent sample t-test and One-way ANOVA were performed to verify difference in mean value of regional safety grade, depending on the injury intentionality, injury location, activities at the time of injury, and injury mechanism, in 6,572 geriatric injury patients by combining the National Hospital Discharge Patients Injury Survey data and regional safety index data. The results of statistical validation suggested that there was no difference in the mean value of regional safety grade by sub-group with respect to the injury intentionality. However, a statistically significant difference was observed in terms of the mean value of regional safety grade in each sub-group with regard to the injury location, activities at the time of injury, and injury mechanism in connection with some areas of the regional safety index. Based on the results of such analysis, we derived and presented 3 implications related to policies and practice for the prevention of geriatric injury and a reduction of its occurrence rate in light of spatial safety after a discussion of the results through a comparison with previous studies that examined individual areas.
