  • Cause of Bucheon LPG refueling station accident could not be clearly verified because of opposite talking of men reponsible for the accident the accident, damaged by BLEVE and fire, and no systematic fire investigation. After two and half years, recently first judgement has been carried out. But competitive arguement is going on and first leak point of massive LPG will not be clearly identified with evidences acquired by now. This accident gave us many instructions and advices. Specially, massive LPG leak can result in pool fire and safety of underground-installed storage tank is proved by no damage in the strong BLEVE.

  • 우리나라에서 발생한 화재 원인조사 대부분은 소방관서에서 초기조사, 경찰관서에서 수사가 진행되고 있으며, 보다 난해하거나 이해관계가 복잡한 경우인 일부만이 경찰에서 심도 있게 조사하고 경찰조사 시 감정이 필요한 경우 감정기관에 감정의뢰 후 경찰관서 자체조사만으로 끝나며, 점차 전문기관에 의뢰되고 있는 건수가 증가하고 있는 실정이나 많은 문제점을 안고 있어 이에 대안을 제시한다. 국내 화재사고 발생 건수는 소방방재청 통계 연간 약 30만 건으로 추산되나, 전국 경찰화재감식 전문 요원(국립과학수사연구소 전문화 교육 이수자)은 80여명에 지나지 않으며, 국립과학수사연구소 화재감정 관련 연구원은 전국에 15명인 것에 비추어 사건화 된 화재에 대한 감식 감정 인력은 턱없이 모자라 과중한 업무를 수행하고 있는 실정이다. 가연성 액체에 의한 방 실화 시 바닥재의 연소형태를 비교 연구함으로써 연소에 사용된 연소촉매제에 대하여 추론 할 수 있는 연구를 실시하여 모델을 제시하였다. 화재사건 관련 감식 감정 업무를 담당하고 있는 경찰 및 국립과학수사연구소의 과중한 업무의 부담인 의뢰 건수의 폭주로, 경찰 화재 감식의 대상 중 범죄혐의(방화, 실화 등)가 있는 사건은 전체 조사 건수의 20% 미만이고, 나머지 80%에 달하는 사건이 범죄혐의 없는 제조물 관련 또는 이재 관계의 민사 소송 사건에 지나지 않는 것이 현실이다. 본 연구는 경찰화재조사 및 소방화재조사에 대한 검토와 문제점 대안 등을 제시하여 화재사건과 관련하여 경찰 소방 양 기관에서 합동으로 사건을 처리하는 것이 과오를 범하지 않는 효율적이고 과학적인 수사가 될 수 있다는 제도개선이 필요함이 요구된다.

  • It is often thought that when a fire is found in parked motor vehicles, the fire may occur after an engine stops. Also, it is easy to judge that when motor vehicle fires occur during engine stopping, it may be caused by arson or electrical causes irrespective of a fuel system. This study analyzed motor vehicle fires which occurred in operation but were found after parking and revealed that these fires were caused by the defect of a fuel system and the same motor vehicle types had fires by the same causes. Moreover, this study provided judgement process of major fire causes and periods for fire investigators to apply when investigating fires of parked motor vehicles. And this fire is related to automotive products liability.

  • In this paper, we intend to establish the judgement of electrical fire through analysis of PT(Potential Transformer) using the power installation. The columnar structure and the void generated by abrupt heat grew at the tenter of boundary-face on the metallurgical microscope analysis. The detection of OK lines was confirmed by EDX(Energy Dispersive X-ray spectroscopy) as melting and recombination due to the layer-short of the wiring. We found that the thermal-weight decrease occurred at 300$^{\circ}C$ in case of being the thermal-deterioration on the base of the result that analyzed the insulated-materials by using TGA, and the thermal reaction limited-value of PT insulator was about 300$^{\circ}C$ on the DSC curve. As this analysis, we confirmed what the layer-short appeared in the wiring of PT.

  • 우리나라 의용소방대 조직의 기능과 역할에 대하여 효율적인 주민방재 조직이라는 평가와 더불어 소방업무를 보조하는 본연의 기능을 수행하지 못한다는 상반된 의견을 제시하고 있다. 이러한 의견 차이에 대하여 한국의용소방대의 특성을 고려할 때 무엇보다도 의용소방대장이 누구이며, 그가 어떠한 리더십유형을 보이는가가 중요한 이유라 할 수 있다. 따라서 본 연구는 대원의 조직몰입을 높일 수 있는 의용소방대장의 리더십유형과 리더에 대한 신뢰를 중심으로 연구를 진행하였다. 분석결과 의용소방대원들의 조직몰입을 증대시켜 의용소방대 조직의 활성화를 통한 지역재난 및 봉사 Network의 효율성 증대를 위해서는 의용소방대장은 전통적인 거래적 리더십 행태보다는 변혁적 리더십을 적극 활용해야 하며, 의사결정방식에 있어서는 민주적 리더십 또는 가부장적 온정형 리더십을 발휘해야 할 것이다. 특히 가부장적 온정형리더십을 적극 활용해 한국적 의용소방대 조직문화의 창출을 이루어야 할 것이다. 또한 리더에 대한 신뢰는 리더십 유형에 관계없이 조직의 성공과 성과 그리고 구성원 간의 이해와 협력을 높여 기대이상의 성과창출을 가능하게 하는 기본적 요소로 인식하여야 할 것이다.

  • For a fire cause judgement this paper describes the short circuit characteristics of a electric wire through the cross section analysis under ac condition. The cower wires prepared for the experiment were 1.2mm, 1.6mm, and 2.0mm in diameter. Through the cross section analysis(CSA), it was confirmed that the dendrite structure grew at the angle of about $40^{\circ}\;or\;60^{\circ}$ when the fusing current was applied to the wires. The larger the fusing current is, the more decreased the growth angle of the dendrite structure is. It was confirmed that the dendrite structure was arranged like the columnar structure. In this paper, the characteristics analysis of short circuit was carried out in the range of transient duration and the correlation constant k was investigated by measuring the short circuit duration and the fusing current.

  • The Russo-Japanese War(1904-1905) in the early 20th century greatly influenced the international politics in Northeast Asia and the destiny of both countries. There are many studies on the cause of the outbreak and its effect on the Korean peninsula. The victory and defeat of the battle of Tsushima also the subject of research by renowned scholars and navy officers. Many previous studies have analyzed the process of engagement. However, There was a lack of research that analyzed at the tactical level of naval commanders. Therefore, this study tries to review the battle of Tsushima in terms of tactical level, that is formation, maneuvering, damage control. Naval operations at sea with many variables are not always done as planned. The intuitive judgement and readiness have had a decisive impact on victory and defeat. The analysis of the naval warfare on the basis of formation, maneuvering, and damage control makes the cause of the win more clearly. The conclusion of the this study can be summarized in five ways. First, victory would be achieved through the suppression of the beginning. The destiny of the Tsushima battle was determined by an 1 hour after first firing. The Japanese fleet caught fire by paralyzing the command and control capabilities of the Russian fleet. Second, the Japanese fleet's power was superior to the Russian fleet. In general, Japan and Russia had similar powers, and Admiral Togo's "T crossing tactics" decisively contributed the victory. However, when compared to the weapon system level, formation and maneuvering, Japan was much more dominant. Third, people realized that one side to be annihilated in the battle between similar powers after the Tsushima battle. The common perception before the Battle of Tsushima was that the battle ship would not sunken, and that the result of wiping out was difficult. However, there is s time for one sided victory and defeat depending on the early suppression nad the destruction of the command and control ability. Fourth, it is the importance of damage control ability. The main cause of the Russian fleet's loss of command and control ability was thick smoke from fire, and maneuverability was greatly deteriorated due to coal overload. In this way, importance is still valid after more than 100 tears. Fifth, the area of uncertainty. In the navy battles, one or two shots of clear firing in the beginning and small misconception and minor mistakes decide win or loss. Ultimately, this area of fortune can be linked to mindset of the commander. I hope this research will be help to naval researchers and naval commanders at the sea.

  • This thesis, deduced from studying eastern and western medical records, deals with geriatric demedtia in modern society. The result were obtained as follows : 1. Dementia is a kind of chronic, progressive, degenerative disease. The chief expression and pathogenic change of the disease is organic: e.g., extensive change such as cerebrum - atrophy, and denaturalization result. in such a situation intellectual capacities and the ability to enjoy daily life deteriorate trenendously. 2. A basic internal cause of the disease is Defficiencies of the heart, liver and kidneys. An exterior cause is an Excessiveness of the 'Dam'(痰), 'Blood Stasis', 'Fung'(風) and 'Fire'. In a Western Medical view, the reason for dementia is due to the onset of Alzheimer's disease and Brain anemia resulting from Multi - infarction or some other reason. If the white - matter of the brain is injured, then dementia easily to results. 3. Disease symptoms result in troubles in intellectual functions : e.g., memory, orientation, intelligence, judgement, common sence and calculating abilities. 4. The proper therapeutic treatment depends on the causes. When the Deficiency is serious, Fortification (heart, liver. and kidney deficiency) is applied and Decrease is follow. When Excessiveness of wrong is serious, the Decrease is tried before the supplement measure is used depending on the deficiency, which generally is used together with 'Fortify Right - Decreace Wrong'. 5. If the disease wasn't caused by some mental reason, it's difficult to be cured of the disease. When the degree of the disease is light and it doesn't continue for a long time, the therapeutic treatment can block the disease's progress and improve the patient's symptoms.
