Growth of minors learning space that the school is a place where many students live. Students, but in the living space of these minors values of change and chaos that occurs in addition to school safety incidents typically occur many accidents and potential for accidents to occur. Tinking of these potential events. Indifferent about the safety of schools and teachers with the much more conscious of the safety of the students lean due to being generated. Body and life, and damage to property due to these events. Accidents due to wear and sometimes liability and indemnity issues surrounding tarnished with the image of the school and teachers look forward to hearing from parents about the school deterioration, resulting in an unfavorable impact. Therefor in this essay, we are presenting case analysis may occur or re-occur. Prevent accidents that can identify and Countermeasures against accidents that occur within the school.

전 세계가 하나의 Global 시대로 전환되면서 국적에 관계없이 기업의 생존이 소비자들의 욕구 를 충족시키는 능력에 따라 결정되는 시대가 되었다. 우리나라의 경우에도 경제협력개발기구(OECD)에 가입한 상황에서앞으로 21C는 외국기업 및 제품들이 자유경쟁적으로 우리시장에 선 보이게 될 전망이 며 우리기업의 제품도 외국에서 다른나라 제품과 치열한 경쟁을 하여야 할 전망이다. 따라서 우리나라 에서도 질이 나쁜 수입품으로부터 국내제품과 소비자를 보호하고 외국으로 수출된 국내제품이 그 나라 에서 이미 시행되고 있는 규제들에 의해 피해를 입지 않ㄷ록 하는 방안이나 정부규제가필요하게 되었는데, 그 중에 대표적인 것이 제조물 책임법(Product Liability)인 것이다. 본 연구에서는 첫째, 외국의 제조물 책임법 시행 현황 및 우리나라 제조물 책임법 시행안에 대해 조사하였으며 둘째, 국내외 제조물 책임 사고 사례를 수집하여 제조물책임법 시행이 소비자와 기업에 미치는 영향등에 대해 분석하였다. 연구결과, 이미 제조물책임법이 시행되어 정착화 되어있는 선진 여러나라의 경우 각국의 제조물책임법 내용은 그 나라의 국가경제, 사회적여건, 자국민을 보호한다는 관점에서 조금씩 차이점을 보이고 있었으며 제조물책임법의 영향 또한 각국의 상황에따라 긍정적 혹은 부정적 영향을 끼치고 있었다. 우리나라의 경우 제품의 안전성을 향상시키기 위해서는 정부의 체계적 정책수립 뿐만 아니라 기업의 제조물책임에 관한 인식 전환 및 대책이 필요한 것으로 조사되었다.

In this study, we discuss a fatal accident severity model obtained from the analysis of 112 crash sites collected since 2000, and the resulting relationship between fatal accidents and roadway geometry design. From the 720 times computer simulations for improving driving safety, we then reached the following conclusions:. First, the result of cross and frequency-analyses on the car accident sites showed that 43.7% of the accidents occurred on the curved roads, 60.7% on the vertical curve section, 57.2% on the roadways with radius of curvature of 0 to 24m, 83.9% on the roads with superelevation of 0.1 to 2.0% and 49.1% on the one-way 2-lane roads; vehicle types involved are passenger vehicles (33.0%), trucks (20.5%) and buses (14.3%) in order of frequency. The results also show that the superelevation is the most influencing factor for the fatal accidents. Second, employing the Ordered Probit Model (OPM), we developed a severity model for fatal accidents being a function of on various road conditions so as to the damages can be predicted. The proposed model possibly assists the practitioners to predict dangerous roadway segments, and to take appropriate measures in advance. Third, computer simulation runs show that providing adequate superelevation on the segment where a fatal accident occurred could reduce similar fatal accidents by at least 85%. This result indicates that the regulations specified in the Rule for Road Structure and Facility Standard (description and guidelines) should be enhanced to include more specific requirement for providing the superelevation.

As the industries become more developed, the amounts of hazardous materials have been increased. Because of that, the possibility of accidents in plants is expected to increase. Especially, the dispersions of toxic materials cause serious effect to human life and environment, So it is very important to confirm safety distance of discharge accident. For this paper, we proposed new algorithms for toxic liquid, such as benzene and acrylonitrile. and using this argorithm, we are going to predict safety distance. The scenario of accidental release was assumed to be the release of entire quantity in 10 minutes is defined as worst-case scenario and Instantaneous release. Also the release from a partial rupture of line is used as an alternative case scenarios as NICS(National Institute of Chemical Safety) guidelines. Using ALOHA program and the algorithm for liquid toxic materials and suggested the graph, as well as correlated equations which can utilize emergency responders.

For traffic safety, it is imperative for motorists to secure their clear view and to maintain a similar speed with others while driving in a lane. Large-sized vehicles at lower speeds, however, are likely to increase the risk of accident when they share a lane with cars. Although to overcome this complication the Korean Road Traffic Act established rules for the safe use of roads, the reality is that the rules are seldom observed strictly. In this light, this study was designed to analyze the severity of truck-involved accidents, thereby providing justification for the need of truck-designated lanes and thus contributing to measuring road safety more precisely. A binomial logistic regression model was applied to analyze the severity of truck-involved accidents. The analysis showed that several variables affect the severity of truck-involved accidents on freeways; i.e., violation against the rule of truck-designated lanes, weather, difference between daytime and nighttime, and parking on road shoulder. Moreover, the strong enforcement will be needed to make motorists observe the rule, because a Wald statistical test showed that the violation against the rule of truck-designated lanes has the largest influence on the severity.

Since the OPRC-HNS Protocol entered into forced in the June of 2007, the potential effects on industrial circles are encouraged to be analyzed according to the obligatory regulations listed in the Protocols. This study was conducted on the quantitative analysis of the possible effect on the industrial circles if Korea accedes to OPRC-HNS Protocol. In spite of any burdens caused by keeping "accident emergency program memorandum" and performing "education and any training program for the crews", potential decrease of insurance fee is in possibility provided it follows. In addition, the oil refinery and petrochemical industries may also have burdens for potential costs for acquiring any materials including equipments and fees for education and training related to HNS. However, minimizing any costs by swift response against accidents would be big advantage that comes with paying of small amounts of expense by international convention related to HNS.

A lot of hazardous materials have been used for product processing and utility plant. Many accidents including toxic release, fire and explosions occur in the ammonia related facility and plant. Various safety and environment management program including PSM, SMS, ORA etc. are being implemented for risk management and accident prevention in the production industry. Also much study and research have been carried about risk assessment of accident scenario in the academic and research area. In this paper, firstly risk level was assessed by using a typically used KORA program and LOPA PFD method for the selected ammonia unloading and storage facility. And then risk reduction measures for the risk assessed facility were studied in 3 aspects and some measures were proposed. Those Risk Reduction measures are including a leak detection and emergency isolation, water spray, dilution tank, dike and trench, scattering protection in hardware impovement aspect, and a applicable risk criteria, conditional modifier for existing LOPA PFD, alternative supporting modeling program in risk estimation methodology aspect, and last RBPS(Risk Based Process Safety) program, re-doing of process hazard analysis, management system compliance audit in managerial activity aspect.

This study was intended to recognize whether speed desire frustration influences in driving stress. Stress desire frustration is the difference between prefer speed and normal speed. As a result, driver's the prefer speed is higher than the normal speed on 4 road condition(high-way, urban-way, residential-way, rural-way). Also, driver's speed desire frustration caused statistical effect in driving stress on 4 road condition. speed desire frustration effect Driving Stress Scale(DSS) 5 sub-scale factors(progress obstacle, traffic circumstance, accident & regulation, regulation obedience, time pressure). This is that driver who experience much speed desire frustration creates high driving stress. Speed desire frustration analyzed high driver and low driver's Driving Stress Scale(DSS) score and overspeed regulation and traffic accident experience difference. As analysis result, speed desire frustration high driver driving stress high appear. However, difference of overspeed regulation experience or traffic accident experience by speed desire frustration did not appear.

In the Chemicals Control Act, a system was implemented to unify off-site risk assessment and risk management plan into the prevention and management system for chemical accidents. Among the hazardous chemicals which have been covered in system, the accident preparation substances are designated as chemical substances that are likely to occur and of which damage scale are likely to be large in the event of chemical accidents. In this study, risks were compared by selecting accident preparation substances with similar regulated quantities. In addition, risk assessment studies were conducted applying the accident scenarios. Four types of materials such as ammonia, hydrogen chloride, carbon disulfide and benzene were selected for the study, and risks were finally analyzed using Safeti 8.0, a quantitative risk assessment program by DNV. As a result, some materials are identified to have high risks comparing to other substances having similar regulated quantities.
