석유류를 비롯한 가연성 액체는 물체간의 마찰작용에 의해 발생한 정전기 방전과 같은 작은 에너지에 의해서도 착화하는 일이 있다. 이러한 종류의 재해 사고에선 착화성이 높은 액체나 가스, 분진 등의 물적 피해뿐만 아니라 다수의 인명 피해를 부르는 일이 있다. 이 때문에 가연성액체의 충진 등에 있어서는 정전기에 의한 화재·폭발 등 사고발생의 위험성을 배려해서 대책을 세우는 것이 필요하다/sup (1)/.(중략)

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.

This study focused on estimating influential factors of traffic accidents and analyzing traffic accident severity of elderly and non elderly using traffic accident data. In order to reclassify elderly and non elderly traffic accident by a statistical method from entire traffic accident data, multiple discriminant analysis was applied. Also ordered logit model was applied for analyzing traffic accident severities using traffic accident severities as an independent variable and transportation facilities, road conditions and human characteristics as dependent variables. As results of the comparison between elderly and non elderly traffic accident, the traffic accident severity was affected by the age, types of traffic accidents, human characteristics and road conditions as well. Also, transportation facilities and road conditions affected to more elderly traffic accident than non elderly. Therefore, traffic accident severity would be decreased with the improvement of transportation facilities and road conditions for the elderly.

Purpose: This study aims to investigate and analyze the status, form and the cause of accidents that occur in theme parks. Method: For the study, we investigated safety accidents of overseas theme parks that were reported to the media using newspaper search program. It also analyzed 710 safety accidents that were collected by the Korea Consumer Agency (KCA), Korea Association of Amusement Parks & Attraction (KAAPA) etc. Results: Overseas theme parks reported by the media have been occurred 40 to 60 times every year. According to the survey data alone, there are 87 safety accidents annually in domestic theme parks, and there are certain patterns in the types of accidents and injuries. Conclusion: This study intends to identify the types and causes of various safety accidents that occur in theme parks, and establish and implement effective safety accident prevention measures.

원전을 가동함에 따라 전열관에서는 SCC(stress corrosion cracking), 프레팅(fretting) 등과 같은 다양한 종류의 결함이 발생된다. 이러한 결함이 발생된 전열관에 대해서는 건정성 평가를 수행하여 계속 가동을 수행하던가, 전열관 막음(plugging) 또는 재생보수(sleeve) 등의 보수 작업을 수행하게 된다. 현행 전열관의 구조 건정성 확보를 위한 방안 중의 하나로 결함의 종류, 위치 등에 관계없이 모든 결함에 대하여 40% 관두께 기준을 적용하고 있다［1］. 그러나 현재 적용되고 있는 40% 관두께 보수기준은 전열관의 파열사고 가능성을 완벽하게 차단하지 못하면서도 과도하게 보수적인 측면이 있다.(중략)

아동에게 적합한 고구려 장기 게임 개발을 위해 Bruner의 EIS 이론을 근거로, 역사상 가장 강력한 힘의 나라였던 고구려 문화를 담은 캐릭터 8종을 개발하였다. 장기 게임은 아동의 집중력과 사고 발달에 유용하며 두뇌발달과 학습향상에 효과적이지만, 본격적인 장기 게임을 하기까지 장기말 종류, 장기말 움직이는 방법, 장기말 배치, 기본 전술 등 익혀야 할 요소가 많고 이것을 배우는 과정이 지루하며 어렵다. 따라서 말의 종류와 이동 방법을 흥미롭게 익힐 수 있도록 3D카드와 플래시 게임을 개발하였고, 캐릭터를 적용한 보드게임을 제작해 보았다.

생활수준의 향상으로 일반가정에서 사용하는 전기용품의 종류도 무척 다양해졌으며 사용량도 급격히 증가되어 이로 인한 전기재해(화재, 감전)가 끊이지 않고 있다. 행정자치부 화재통계 연보에 따르면 ''99년도 총 화재발생건수 33,856건 중 전기로 인한 화재가 11,204건으로 33.1$\%$의 높은 점유율을 보이고 있어 일반가정에서의 전기안전 생활화가 절실히 요구되고 있는 실정이다. 일반 가정생활에서 편리하게 사용하고 있는 전기를 보다 더 안전하게 사용하기 위해서 우리 모두가 꼭 알아두어야 할 전기설비에 관한 기초상식, 전기사고의 종류와 예방대책, 정전 시 대처요령 등을 알아본다.

As a result of investment in railway safety since 2004, railway accidents have been reduced by half and we reached a high level of safety compared to other countries. But people are still worries about railway accident, and want safer railway. It is difficult to determine which level of safety must be achieved due to lack of comparative studies on railway safety among different countries and other transportation modes. In this study, a comparative study on railway accident statistics and various transportation modes is performed. The results of this research can be used for the determination of weak areas of railway safety and the level of safety to be achieved.

HNS, including crude oil and products, shipments have increased. The risk analysis of HNS has assumed the importance, especially in maritime transportation area. There are various forms and kinds of HNS and the consequences of an accident are serious. In order to provide practical measures for preventing accidents, this study analyses the potential risks of HNS on maritime transportation accidents at domestic sea by using Event Tree Analysis. This study carries out risk assessment with F-N curve and risk matrix focusing on liquid cargo carriers (Oil and Products Tanker, Chemical Tanker, LPG/LNG Tanker, etc.). Explosion and sinking, suffocation indicate high consequence when on collision represent high probability. Improving human errors should be the main factor to mitigate risk on human lives.

The loss of life and property due to accidents in the research facilities or the laboratories of the university occurs steadily and the necessity of laboratory accident prevention is proposed. Above all, the main work to laboratory accident prevention is a systematic analysis of laboratories accidents. Analyzing reports or researches on industrial accidents in Korea had been carried out but these researches or reports did not based on laboratory accidents analysis. To the establishment of the accident prevention countermeasure in laboratory, a questionnaire sheet has been developed in this study. The questionnaires to survey the accident cases were gathered by electronic mail and visit survey from the laboratories and universities. The data of accident cases from the questionnaires was analyzed and discussed on accident distribution by season, the type of accident classification, the type of occurrence, the objects that caused the accident and laboratory accident by the damage incurred etc.. These results of this study can be used as basic data to the safety security and laboratory accident prevention of the laboratory worker.
