In the inspection of workplace hazards/risk factors by specialized institutions dedicated to safety management, inspection reports vary based on the inspectors, who lack the authority to enforce improvement of workplace hazards/risk factors. Thus, improvement and accident rates remain steady without decreasing. This study performed a regression analysis on the relationship between improvement and accident rates of categorized inspection items by classifying hazards/risk factors from inspection reports submitted by a specialized safety management institution in Chungbuk after inspecting 10 food and beverage manufacturers over the past three years. The hazards/risk factors were classified into five categories: mechanical, electrical, chemical, human, and environmental. The regression analysis revealed that the improvement rate of hazards/risk factors inspected by the specialized safety management institution influenced accident rates. To enhance improvement rates based on these findings, this study prioritized the correction of the five most frequently cited inspection items with the lowest improvement rates in each area. Based on these inspection items, this study suggested a checklist for use in workplace safety inspections of food manufacturers. This proposed checklist is expected to reduce accident rates in food manufacturing facilities. Currently, guidance and inspection of workplaces are mainly focused on accident rates rather than correcting hazards/risks. Thus, accident rates remain unchanged as workplace risks are inadequately improved according to the unique characteristics of each workplace. When conducting workplace guidance and inspection, policy measures and inspection methods are warranted to increase the improvement rate of hazards/risks.

Recently, a massive loss of life and property is occurring in Korea due to traffic accidents, with the rapid increase in cars. For improvement of traffic safety, the Korea Transportation Safety Authority intensively analyzes accident data in local governments with low traffic safety index, performs a field investigation to extract problems and offers local governments improvements for problems, by conducting the 'Special Survey of Actual Conditions of Traffic Safety' each year, starting 2008. But local governments cannot strongly push forward the improvement projects due to the limited budget and the uncertainty of the improvement plan effects. Therefore, this study suggested a model which applied the Utility concept to the AHP theory, in order to efficiently decide a priority of the improvement plans in accident black spots in consideration of the limited budget of local governments. The number of accidents in each spot for improvement and accident severity, traffic volume, pedestrian volume, the improvement project cost and the accident reduction effect were chosen as evaluation factors for deciding a priority, and data about the improvement plan costs and the accident reduction effects, traffic accidents and traffic volume in the spots to undergo the special research on the real condition of traffic accident in the past were collected from the existing studies. Then, regression analysis was carried out and the Utility Curve of each evaluation factor was computed. Based on the AHP analysis findings, this study devised a priority decision method which calculated the weight and the utility function of each evaluation factor and compared the total utility values. The AHP analysis findings showed that among the evaluation factors, accident severity had the biggest importance and it was followed by the improvement plan cost, the number of accidents, the improvement effect, traffic volume and pedestrian volume. The calculated utility function shows a rise in utility, as the variables of the 5 evaluation factors; the number of accidents, accident severity, the improvement plan effect, traffic volume and pedestrian volume increase and a fall in utility, as the variables of the improvement plan cost increase, since the improvement plan cost is included in the budget spent by a local government.

신호교차로 교통사고는 도시가 발달하고 산업이 고도화됨에 따라 교통혼잡 문제와 함께 심각한 사회문제로 대두되고 있다. 특히 이와 같은 교통사고는 대부분 인적 요인, 차량적 요인, 환경적 요인 등이 상호 복합적으로 작용하여 발생한다. 이전 교통사고와 교통량과의 관계는 운전자 과실과 함께 교통사고 발생에 주요요인으로 작용하고 있다. 본 연구에서는 교통사고 예측모형을 개발하기 위해 1996년부터 1998년까지 3년 동안에 실제 광주광역시 4-지 신호교차로 73개소에서 발생한 교통사고자료를 기초로 하였다. 또한 4-지 신호교차로 교통사고 분석에 단순통계분석과 교차분석 및 다중회귀분석을 사용하였다. 특히 다중회귀분석에는 교차로 사고분석을 위해 사고유형을 종속변수로, 방향별 접근 교통량을 독립변수로 각각 적용하여 교통사고 예측모형을 도출하였다. 그리고 본 연구에서 도출된 예측모형을 이용하여 전라남도 4-지 신호교차로에 대한 교통사고 잦은 지점으로 선정된 30개소를 선택, 사고유형을 분석한 후 교통사고 예측모형에 적용하여 사고모형을 검증하였다. 결론적으로 본 연구에서는 사고유형과 방향별 접근 교통량과의 관계를 이용하여 광주광역시 4-지 신호교차로 교통사고 예측모형을 개발하였고, 향후 연구과제로 타 지역 신호교차로 교통사고 예측모형 연구와 교차로 교통사고에 대한 안전대책 및 안전한 교차로 설계에 대한 지속적인 연구가 수행되어 져야 할 것이다.

2006년 9월 국무조정실이 수립한 교통사고 잦은 곳 개선 종합대책에 의하면 전방신호기 설치가 교차로 교통사고에 괄목할만한 효과라고 판단하여, 교통사고 잦은 곳 개선사업에 우선적으로 전방신호등을 설치를 권장하고 있다. 하지만 전방 신호등의 효과에 대한 검증 없이 국무조정실이 수립한 종합대책을 토대로 전방신호등 개선사업을 시행한다면 오히려 교통안전측면에서 더 큰 시행착오를 범할 수 있다. 이에 본 연구는 전방신호등의 설치가 과연 얼마만큼의 효과가 있는지, 또한 전방신호기의 설치에 따른 교통사고 유형의 변화 및 전방신호기의 설치가 적합한 교차로 유형에 대한 분석결과를 제시하고자한다. 이를 위해 Hauer가 개발한 비교그룹방법(Comparison-Group, C.G Method)을 활용하여 분석한 결과, 전방신호등 설치로 인한 전체 교통사고 감소효과에는 긍정적인 결과로 나타났으나 교차로의 규모별, 교통사고 유형별 효과분석에서는 각기 상이한 결과를 나타내기도 하였다. 소규모 교차로에서는 교통사고 유형별로 모두 전방신호등 설치로 인한 감소효과가 나타났지만, 대규모 교차로의 경우 정면충돌 및 측면직각 교통사고 유형에서는 오히려 전방신호등 설치로 인하여 교통사고가 증가하여 교통안전측면에서는 부정적인 결과를 초래하였다. 따라서 대규모 교차로에 전방신호기를 설치 할 경우에는 교통운영 및 교통시설, Human Factor 등 다각적인 측면에 대한 개선안을 신중하게 고려하여 시행 할 것을 권장하는 바이다.

Background: Safety climate and occupational stress are related with occupational accident. The present study tried to identify the differences in safety climate and occupational stress according to occupational accidents experience and employment type (e.g., direct workers and subcontract workers). Methods: In this study, we conducted a survey using safety climate scale and Korean Occupational Stress Scale and classified the participants into four groups: direct workers working for accident-free departments, direct workers working for accident departments, subcontract workers working for accident-free departments, and subcontract workers working for accident departments for 2 years within the same workplace in the shipbuilding industry. Results: The direct workers and subcontract workers showed diverse results in subscales of safety climate and occupational stress. This result is supported by existing studies; however, further study is necessary for more supporting evidence and elaborative methodological approach. Conclusion: The necessity of management for safety climate and psychosocial factor such as occupational stress for both direct workers and subcontract workers as a whole is suggested by this study.

There are many accident causes related to even an accident. As well four(4) stepped causes of one accident at construction sites are analyzed in the study. First, eleven(11) cause factors are set up at each step such as policy level, management, indirect, direct level which are discussed and determined by field experts with 15year experience or more. Therefore, one direct cause occurred in construction site can be connected to the previous cause than in direct and management, and policy problem of previous management. These questionnaires results are analyzed with three different methods such as weighing level by Delphi technique, correlation analysis, critical pass method. Three different methods show their characteristic to see which subcontract work is more dangerous or not. Subcontract or at a construction site can be use the above three different cases as they need at their site in order to make more effective countermeasures.
