일반도로구간에서의 사고발생건수는 2000년부터 2006년까지 감소추세를 보이는 반면 교차로에서의 교통사고건수는 현재까지 꾸준하게 증가하고 있기 때문에 교차로에서의 안전성을 증대시키기 위한 노력이 절실히 필요한 실정이다. 본 연구에서는 신호교차로에서의 도로조건, 교통조건, 교통운영상의 조건 등을 분석하여 교차로의 설계 안전성을 저해시키는 요인들을 찾아내고, 그 요인들과 사고와의 상관관계를 이용하여 지방부 4지 신호교차로의 안전성 판단을 위한 사고예측모형을 개발하고자 한다. 또한 사전에 위험요소를 제거하여 교차로에서의 안전성 평가를 위한 가이드라인을 제시함으로써, 교차로에서의 안전성을 높이는데 그 목적이 있다. 본 연구는 교차로에서의 사고분석을 위하여 비선형 회귀분석을 통해 사고모형을 개발하였고, 이러한 모형들을 이용하여 차대차 사고에 영향을 미치는 주요 설명변수들에 대한 분석을 시도하였다. 모형분석결과, 포아송회귀분석(Poisson Regression)이 모형개발에 가장 적합한 것으로 나타났으며, 사고에 영향을 미치는 변수로는 좌회전 전용차로, 횡단보도, 제한속도, 조명시설, 교차각, ADT 등으로 분석되었다.

High temperatures and humidity in summer strongly affect conditions of construction workers. These could lead to safety accidents and results in fatal accidents. This study, based on 3 years of weather and fatal accident data, explains the association between fatal accidents in summer and discomfort index and proposes management directions.

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.

Low birthrate is causing a reduction in the number of students at kindergartens, elementary schools, middle schools and high schools nationwide and yet, school safety accidents are on a constant rise, which was reported to be 237 accidents a day on average in 2011. Such phenomenon is proving how the school safety policy is not doing what it was supposed to do. In order to decrease the school safety accidents, first, causes of the accidents should be analyzed and then, prevention measures should be designed. For that reason, the study looked into the present condition of the school safety accidents and safety accident theories and based on the results, "School Safety Accident Analysis Matrix Model" was proposed. With a matrix method of the accident types (17 of them) and hazard factors (9 of them) applied, the concerned model analyzed a total of 153 accident causes. In consideration of the results from the analysis, the study suggested that the education authority should open a safety organization and design a school safety policy that would systematically deal with safety education, prevention measures practice, accident investigation and analysis, and countermeasures practice as well.

Two studies were conducted to examine the relationship between self-efficacy beliefs and industrial accidents. In the preliminary study, focus group interviews were conducted with employees working in manufacturing and construction sector, safety managers, and government officials to understand factors that were associated with industrial accidents. Based on interviews, a questionnaire survey was constructed to assess individual factors (such as self-efficacy beliefs, following safety procedures, life-satisfaction, and stress) that were identified as affecting industrial accidents (such as minor and major accident rates). The questionnaire were administered to a total of 917 respondents (542 employees working in the manufacturing and construction sector, 210 safety managers, and 165 government employee officials overseeing government regulations). The result indicated that three subscales of self-efficacy for employees (self-regulation, enlisting social support, and controlling the environment) were negatively correlated with the company's industrial accident rates. Moreover, those employees with higher self-efficacy were more likely to follow safety procedures and had higher life-satisfaction and lower stress levels. For safety managers, the self-efficacy beliefs were positively correlated with better implementation and higher effectiveness of the educational programs and negatively correlated with their company's accident rates.

Compared with past, helicopters have remarkably high level of safety and accidents due to mechanical defects are decreased about 15%. Most of their duties, however, are to commit at duty area which is hard to access. Because of them, collision probability is high and also has relatively higher accident rates than other aircraft with special mission. A result of analysis is that accident rate is relative high with prevention of disasters, putting out a fire and crop-dusting missions under 500ft. In addition, most of accidents are related with human factors. According to this, it is required to pilots who carry these mission that safety education and detailed analysis about their mission.

In this paper, we investigated the relationship between the variables of the industrial accident factors and the manufacturing performances such as production quantity, quality, cost, and delivery. For this investigation, we collected the real data from 30 small/medium-sized manufacturing industries by performing a questionnaire survey and a on-site inter-view with the workers. Thirty industries were made up of 10 from each of the following three industries: metal processing, machinery manufacturing, and chemical products manufacturing. The data analysis was made using SPSS PC+. Based on the result of the analysis, we came to the tentative conclusion that only two variables such as work skill and load affected all four manufacturing performances and the rest of them two or three performances.

The more the lift environment eastern idea, culture, factory automation system and information technology complicates, the more the various human error brings about. It brings about all kind of accidents and occupational diseases. Also the death and sickness or injury by psychological stress among the human error has increased every year. Therefore this paper describes the Korean lift change unit model through statistical testing with the proposed life change unit factors on the married workers living the middle area. The proposed model can be simply used in order to minimize the industrial accident and human error in real fields. Finally, the result will be helpful for the better safety management.

Generally a road vehicle's wrong entry into level crossing gives rise to hazardous events, the eventual collision with a approaching train depends on the effective operation of safety barriers such a abnormal condition detecting or emergency braking. In this paper, the risk assessment models developed for the level-crossing accidents will be introduced. The definition of hazardous events and the related hazardous factors are identified by the review of the accident history and engineering interpretation of the accident behavior. A probability of the hazardous events will be evaluated by the FTA, which is based on the accident scenario. For the severity estimation, the critical factors which can effect on the consequence will be reviewed during the ETA. Finally, the number of casualty for the public(vehicle drivers) and the train passengers are converted into an equivalent fatality.

With Zohar(1980)'s research on safety climate and industrial safety, occupational safety and health literatures begin to emphasize the influence of organizational context. Based on this research trend, this paper tried to review the relationship between individual/ organizational factors and occupational accidents. Based on the responses from 294 manufacturing workers, this paper reviewed the relationships among safety climates, safety performance, and age. The results of statistical analysis showed that all safety climate factors have affirmative effects on safety participation and safety attitudes negative effect on accident number, and job load affirmative effect on accident number. Job load and management commitment showed interactive effects on accident number with age.
