Accident rate in domestic construction industry has been increased rapidly in every year. In particular, the rate of death has been shown very high compared with other industries. It means that safety activities performed by government is not effective in reducing the rate of accident. To solve these problems, the risk factors should be predicted in advance, controlled, monitored and managed from start of project to end of project. However, most studies have been conducted by using frequency of occurrence of accident and only listed the importance of risk. Therefore, the objective of this study is to provide basic material to develop risk quantifying model for human accidents on construction site in South Korea. In the future, it is expected to be used as a reference of study on developing safety mangement checklist in construction industry and model for forecasting accident.

In this study, the effect of damping and elastic nature on the control performance of a safety budget-industrial accident rate model in Korea is examined first. The effectiveness of such dynamic model in establishing safety policies is shown with a simple proportional-integral(PI) feedback control mechanism. Control performance of the safety system model is explained in view of maximizing the effect of IAPF and minimizing the absolute amount of IAFP. Control performance is then evaluated and proved to be effective to prevent and reduce the industrial accidents. Implications in feedback control of a safety system model suggested to optimization of safety policies are also explored. Without proper restructuring of the safety system, it would not be possible to hit the target industrial accident rate. Even if the control objective is met, the amount of industrial accident prevention fund required to reduce the industrial accident rate from the current level to the target level would be far beyond the social consensus.

This study focuses on the issue of control performance of safety budget for preventing and reducing industrial accidents in Korea. The effect of safety budget such as industrial accident prevention fund on the safety performance is statistically examined first. The role and control performance of industrial accident prevention fund is particularly addressed to reduce the related accidents. The effectiveness of the industrial accident prevention fund-industrial accident relationship is then explained with a simple PI control mechanism.

용량의 산정이 적합하지 못하다면 고속도로의 분석 및 예측에 잘못된 결론을 도출하게 된다. 도로의 용량을 일시적으로 크게 감소시키는 교통사고는 예측 불가능한 비반복정체를 발생시켜 혼잡관리가 어렵다. 따라서 본 연구는 사고발생시 속도에 따른 도로용량 파악을 목적으로 한다. 본 연구에서는 사고발생구간의 차량의 행태를 파악하여 교통류 속도에 따른 임계차두간격 산출모형과 최대통과교통량 산출모형을 구축하였다. 구축된 모형을 토대로 사고발생시의 고속도로용량감소율을 산정하였다. 그 결과 교통류의 속도가 40km/h일 때, 도로용량이 37%감소할 것으로 예측되었고, 다른 결과값은 본문에 수록하였다. 구축된 모형에 대한 검증은 제대로 수행할 수 없었지만 속도에 따른 도로용량감소율을 파악하고자 했다는데 본 연구의 의의를 두고 싶다.

2022년 1월 27일부터 시행된 중대재해처벌법은 안전조치를 소홀히 한 사업주나 관리자를 중대재해 발생 시 1년 이상의 징역형에 처하도록 하고 있다. 이 중대재해의 처벌에 관한 법률이 올해부터 시행되면서 사회의 많은 관심을 받고 있다. 전문가들에 따르면 안전사고율을 낮추는 법안의 당초 취지와 달리 기업에 대한 처벌을 높이는 데 초점을 맞춰 법안을 만들었다는 의견이 대부분이다. 본 연구는 사례연구를 통해 이러한 내용이 사실인지를 확인하였으며, 이를 지속할 경우 기업과 근로자 간의 갈등이 심화되어 안전사고율이 감소하지 않을 것이다. 따라서 본 연구는 기업의 처벌을 무조건 늘리는 것이 아니라 설문조사를 통해 많은 상황을 비교하고 기업과 근로자가 안전사고율을 낮추기 위해 중대재해처벌법에 협력할 수 있는 방안을 제시하였다. 본 연구는 안전한 사회 건설을 위한 발전된 중대재해 처벌 법의 제정을 위한 기초자료로 활용될 것으로 사료된다.

Due to the increasing of the number of cars and bad road conditions, car accidens are increasing every you in Korea. When a person meets a car accident, it is necessary for him to analyze and determine whether applying insurance or not, because standard discount rate and special increasing rate change with accident types and the amount of accident expenditure. When we consider insurance rate that includes more then ten elements, we need a decision making, In this paper, S insurance company investigated previous car causers in 1988, 1989, 1990 to 1996 with 600,000 real data. We investigate probability density functions and cumulative distribution functions for each year using ARENA software. We can apply the results of this study to various accidents that occur under uncertainty in our life. I hope that this paper contribute to strengthening competitive power of companies and developing new insurance rate systems in future.

Background: From only frequency rate of industrial accidents, it is difficult to define the industry composition of accident statistics in a nation. This study aims to propose and develop a new index for measuring the degree of concentration of industrial accidents using the concept of the Herfindahl-Hirschman Index in the case of European countries. Methods: Using the concept of the Herfindahl-Hirschman Index, the concentration index of accidents in the country is developed, and the conditions of European countries are compared using indexes of frequency rate and concentration ratio. Results: The frequency rate and concentration ratio of fatal and nonfatal accidents in European countries are compared. According to the economic condition and geographical position, different patterns of accidents concentration are presented in terms of frequency rate and concentration ratio. Conclusion: We develop the concentration index of industrial and occupational accidents that identifies the industrial ratio of accident occurrence, and the differentiated strategy can be formulated such as approaches to reducing frequency and prioritizing target industries.

The workers of limestone industry have relatively higher rate of accident and injury than other industry workers. This survey was conducted to provide the informations for the planning of safety and health educations to prevent the accident and injury. The purpose of this study is to identify the morbidity rate per month and to determine the related health factors, and to find accident experiences of the limestone workers and to analyze the reasons and types of that accidents. The study design was a descriptive survey. Self reporting questionnaires developed by researcher were used for data collection. The subjects of this study were 225 workers in limestone industries in Jecheon city. The statistical methods utilized for data analysis were frequency analysis, $x^2$-test with SPSS-pc(ver.9.0). The results are as follows, 1. The workers morbidity rate per month was 22%, and morbid factors were Flu., G-I trouble, hypertension, orthopedic trauma, external wound, burn, etc., and the related health factors are self-assessment for health, exercise, accessability for medical facilities. 2. 40% of the subjects have experienced the accidents during last 6 months. The types of the accidents were safety violations, traffic accidents and fire accidents. Injury types were external wounds, fracture/amputation and burn. The workers of limestone industry have higher morbidity rate and experiences of accidents. Therefore the more increased safety and health educations than now for both the workers and the managers are needed. And this study could be helpful to increase the quality and the quantity of the educations needed.

현재 우리나라 간선도로의 서비스수준(LOS)은 차량의 평균통행속도를 기준으로 평가되어지고 있다. 이는 도로의 혼잡도 만을 기준으로 적용한 것으로 교통안전측면이 고려되지 않은 것이 현실이다. 합리적인 도로 설계와 운영을 위한 평가 지표라면 도로 이용자에게 영향을 미치는 제반 인자들을 보다 포괄적으로 포함할 수 있어야 한다. 교통안전과 소통측면을 총괄할 수 있는 변수로 사용자비용 개념을 적용하여 간선도로 평가방법을 모색하고자 한다. 사용자 비용을 효과척도로 하는 간선도로 평가도 가능하다는 것을 본 연구를 통해 알 수 있었다. 또한, 본 연구의 사용자 비용에 의해 평가된 간선도로 서비스 수준과 도로용량편람의 평균통행속도에 의해 평가된 간선도로 서비스 수준을 비교 분석하여 종합적인 서비스 수준 분석방법 여부를 가릴 수 있을 것이다. 이로서, 안전과 소통 측면을 모두 고려한 간선도로 평가가 가능함을 알 수 있었다.

Background: Truck driving is known as one of the occupations with the highest accident rate. This study investigates the characteristics of traffic collisions according to road types (expressway and rural road). Methods: Classifying 267 accidents into expressway and rural road, we analyzed them based on driver characteristics (age, working experience, size of employment), time characteristics (day of accident, time, weather), and accident characteristics (accident causes, accident locations, accident types, driving conditions). Results: When we compared the accidents by road conditions, no differences were found between the driver characteristics. However, from the accident characteristics, the injured person distributions were different by the road conditions. In particular, driving while drowsy is shown to be highly related with the accident characteristics. Conclusion: This study can be used as a guideline and a base line to develop a plan of action to prevent traffic accidents. It can also help to prepare formal regulations about a truck driver's vehicle maintenance and driving attitude for a precaution on road accidents.
