충전소에서 일어난 사고를 1987부터 1998년까지 사고자료를 근거로 하여 사고 시나리오와 사고발생 초기의 피해거리를 살펴보고, 이를 바탕으로 국내$\cdot$외 안전거리를 비교$\cdot$검토하여 적절한 안전거리에 대하여 살펴보았다. 안전거리는 시설과의 최소한 이격거리를 두어 사고 발생시 점화가능성을 줄이고 원활한 방재활동과 피해확산을 방지하기 위한 것으로서 가스누출시 제트화재의 길이 또는 누출가스의 연소하한농도의 도달거리와 관계가 있으며, 안전장치 설치현황, 안전관리자의 의식수준, 그리고 경제성을 검토하여 안전거리를 결정할 수 있도록 저장량에 따른 안전거리의 범위를 제시하였다.

According to the Marine Traffic Safety Law, revised in 2009, Marine Traffic Safety Audit is introduced to secure the safe navigation, to prevent the marine accident and to maximize the efficiency of the port. In this audit system, marine traffic safety assessment is the most important scheme because the primary purpose of the audit system is to identify potential risk elements affecting safe navigation. Even though the reliability of audit result depends on the selection of assessment models, there are no independent assessment models for Korean coastal waters and most of models used in Korea currently are developed by foreign countries. Therefore, the development of the independent assessment model for Korean coastal water is required. This study, prior to the development of independent assessment model, aims to provide a basic data by comparing two foreign assessment models in Ulsan port area with marine accident statistics data.

The school is the educational and living space for students and teachers. And, the safety of the school facilities is very important element on the school activities. For this safety of school facilities, there is a need to prevent of safety-accident by the reinforcement of the systematic and the removal of risk factors. In order to minimize the damages from school facilities this study tried to suggest the solution for the prevention of safety accidents according to research about actual conditions of safety accidents from school facilities.

This study was carried out to obtain baseline data on the causes of industrial accidents and their prevention by investigating structural models between the Shipyard workers' egogram ego-states (CP: Critical Parent, NP: Nurturing Parent, A: Adult, FC: Free Child, AC: Adapted Child), safe and unsafe behaviors, and industrial accidents (frequency/severity). In order to achieve this goal, 378 workers from 3 locations of major corporations in Geojedo Island and Ulsan took a questionnaire, which was then analyzed with a structural equation model using the SPSS 23.0 and AMOS 24 statistics package, and the main results of the study are as follows. First, NP and A's ego-states had a positive influence on safe behavior, AC's ego-state had a negative influence on safe behavior, and A's ego-state had the largest influence on safe behavior. Second, CP and AC's ego-states had a positive influence on unsafe behavior, and A's ego-state had a negative influence on unsafe behavior. AC's ego-state had the largest influence on unsafe behavior. Third, safe behavior did not have a significant influence on industrial accidents. However, unsafe behavior had a positive influence on industrial accident frequency and industrial accident severity, both sub-factors of industrial accidents. This study, despite its limitations, such as sampling limitations, has the following significance. First, this study verified that ego-state, a psychological characteristic, is an important factor for predicting unsafe behavior that induces industrial accidents. Second, in order to reduce industrial accidents, there is a need to stimulate the A ego-states, and promote continuous safety management and safety education to neutralize the AC ego-state. Third, previous studies were limited in the area of practical methods for reducing unsafe behaviors, but this study presents practical methods for reducing unsafe behaviors by verifying the structural relationship between safe/unsafe behaviors and industrial accidents by selecting ego-gram ego-states, variable personality theory, as an independent variable.

유독물 취급업체수가 증가하고 취급업체들이 다루는 물질의 종류가 다양해지고, 그 양도 증가함에 따라 국내 화학 사업장 사고의 심각성을 보여준 대표적인 사례로 2012년 구미 불산 사고를 들 수 있다. 화학사고 발생 시 화학물질 특성과 주변 환경에 따라 효과적으로 대응책을 마련하기 위해서는 예측모델의 활용이 반드시 필요하다. 현재 존재하는 다양한 예측모델들은 실험을 통해 그 정확도를 검증된 적은 있지만, 예측모델들간의 계산 결과 비교를 통해 어떠한 경우에 어떤 모델이 가장 적합한지에 대한 활용성 부분이 부족한 실정이다. 본 연구에서는 구미 불산 사고를 사례연구로 선정하고 불화수소의 누출과 확산에 가장 정확하다고 알려진 HGSYSTEM을 이용하여 농도를 계산하였다. ERPG-2 기준농도 기준으로 사고 지점으로 부터 1 km 이상 확산됨을 확인하였다. 이 결과를 바탕으로 ALOHA와 CARIS의 결과를 비교하여, 가장 대표적인 예측 모델들의 활용성을 분석하였다.

본 연구는 1997년부터 현재에 이르기까지 전국에서 발생한 스쿠버다이빙 사고 자료를 수집 및 분석하고 일본 및 미국에서 발생한 다이빙 사고와 비교분석하여 우리나라 스쿠버다이빙 사고의 특성 및 문제점을 밝혀내 개선책을 제안하였다. 연구 결과는 잠수 사고 예방에 큰 기여를 할 수 있을 것으로 기대된다. 사고 자료는 대한수중협회의 기술위원회에 보고된 자료와 해양경찰청의 자료, 스쿠버 다이빙 전문점에 전화 통화 및 방문조사를 실시하여 얻은, DAN(Diver Alert Net-work)에서 발행한 다이빙 사고보고 자료집, 월간잡지에 수록된 잠수사고 보고 자료, 그리고 세미나 발표 자료 등을 참조하였다.

There are insufficient models that find problems and solutions for accident prevention through risk assessment and suggest safe work process and work instruction from foundation works to finish work for accident decrease. This paper presents a quantitative risk assessment model by analysis of risk factors in each process such as foundation, erection, structure, equipment finish and etc based on accident examples and investigation on actual condition in building. In addition, the safety management system was developed to perform risk assessment of construction and use it for effective safety training for labor.

The number of big traffic accident cases of pedestrian death appeared to be minor, however compared to death rate in car to car accidents is very high and quite a few of the pedestrian death rates among all traffic accidents are counted to be almost 40%. Previous pedestrian safety studies were mostly aimed at reducing the degree of pedestrian injuries from a vehicle to pedestrian collision, and less at preventing a collision itself. This research was conducted with a method of using road facilities to prevent vehicles from rushing into the sidewalk. This research used one of the collision analyzing programs, called PC-Crash to simulate the vehicle rushing into the sidewalk. Based on the program, it could derive an optimal safe zone location where the pedestrian can wait for the pedestrian light safely. Also, changing road facilities such as pedestrian light pillars or signal controllers can widen 440% compared to the present safe zone. Accordingly, researchers have to consider a method to analyze and apply pedestrian safe zones along with road facilities location when designing a road.

Even though cars have a good effect on modern society, traffic accidents do not. There are traffic laws that define the regulations and aim to reduce accidents from happening; nevertheless, it is hard to determine all accident causes such as road and traffic conditions, and human related factors. If a traffic accident occurs, the traffic law classifies it as 'Negligence of Safe Driving' for cases that are not defined by specific regulations. Meanwhile, as Korea is already growing rapidly elderly population with more than 65 years, so are the number of traffic accidents caused by this group. Therefore, we studied predictive and comparative analysis of the number of traffic accidents caused by 'Negligence of Safe Driving' by dividing it into two groups : All-ages and Elderly. In this paper, we used empirical monthly data from 2007 to 2015 collected by TAAS (Traffic Accident Analysis System), identified the most suitable ARIMA forecasting model by using the four steps of the Box-Jenkins method : Identification, Estimation, Diagnostics, Forecasting. The results of this study indicate that ARIMA $(1, 1, 0)(0, 1, 1)_{12}$ is the most suitable forecasting model in the group of All-ages; and ARIMA $(0, 1, 1)(0, 1, 1)_{12}$ is the most suitable in the group of Elderly. Then, with this fitted model, we forecasted the number of traffic accidents for 2 years of both groups. There is no large fluctuation in the group of All-ages, but the group of Elderly shows a gradual increase trend. Finally, we compared two groups in terms of the forecast, suggested a countermeasure plan to reduce traffic accidents for both groups.
