최근 선박건조기술이 발전했음에도 불구하고 교통량의 증가와 해양레저의 활성화로 사고위험은 더욱 증가하고 있다. 이 논문에서는 그동안 발생했던 해양사고를 분석하여 사고발생을 최소화할 수 있는 여러 가지 방안과 사고발생시 신속하고 구조할 수 있는 체계적인 구조시스템에 대하여 논의한다. 선박이 해상에서 안전하게 항행하기 위해서는 선박기술, 항해관련 장비, 우수한 인적자원, 교통관제 등과 같은 구성요소들이 제도적으로는 구축되어야 하고, 각각의 항행요소들이 유기적으로 작동되어야 한다. 또한 사고발생시 사고수습이 신속하게 진행될 수 있도록 체계적으로 정부조직이 구성되어야 하고 그 조직들이 긴밀한 협력관계를 유지해야 한다. 민간부분에서의 협력지원도 현재보다 더욱 강화되어 국가의 관리영역에서 벗어난 해역에서는 민간부분에서 구조할 수 있도록 민간 구조대가 활성화되어야 한다.

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.

We construct the procedure to predict safety accidents following Bayesian approach. We make a model that can utilize the data to predict other levels of accidents. An event tree model which is a frequently used graphical tool in describing accident initiation and escalation to more severe accident is transformed into an influence diagram model. Prior distributions for accident occurrence rate and probabilities to escalating to more severe accidents are assumed and likelihood of number of accidents in a given period of time is assessed. And then posterior distributions are obtained based on observed data. We also points out the advantages of the bayesian approach that estimates the whole distribution of accident rate over the classical point estimation.

The purpose of this study is to collect and analyze their opinions to found solutions for reducing safety accidents since it is important to educate the students to recognize the importance of safety. We surveyed 350 students from mechanical and metal engineering departments of an engineering high school located in Seoul, and divided them in two categories and asked them about prevention of safety accidents in laboratories. It is found that further directions and educations are needed for the students as to emergency measures in case of safety accidents. Safety education before laboratory classes is crucial, helpful and effective for prevention of safety accidents. Facility factors that further education is needed for students who don't experiments in orderly manner.

Marine casualties of fishing vessels were analyzed to reduce the sacrifice of human life using data of the Korean Maritime Safety Tribunal from 1995 to 2004 in Korea. The occurred number of fishing vessel casualties were likely to be higher portion than non-fishing vessels, but the occurring ratio of fishing vessel casualties were marked 2.96 times lower than that of non-fishing vessel casualties. The occurring ratios of bigger fishing vessel casualties were higher than smaller ones. Most marine casualties were resulted from the human factors such as poor watchkeeping, negligent action for engine and etc. The trend of marine casualties showed that the machinery damage hold the first and collision accidents took the second, but on a point of cause of them, operating errors took first and poor handling or inspection of machinery held the second place. Because those two casualties took major portion, and very important problems for safety of fishing vessels, so we ought to try to reduce the factors before everything else. In addition, since collision, sinking and capsizing in marine casualties have led to death, missing and injury of lives, it is necessary for navigation operators to take more educations and training intended to reduce the marine casualties systematically and continuously.

Since Zohar(1980) emphasized the influence of social, organizational, and psychological context in occupational safety and health study, the research in this area tends to be emphasizing the influences of personal and physical interaction. With this research trend, this paper is to examine the relationship between safety climate model and safety accident, and the interactional or moderating effect of personal and physical factor on the above relationship. Author conducted a survey to 292 manufacturing workers in construction industry, and the chief results of statistical analysis are as follows 1) management involvement, safety education, precaution activities, and safety system have negative effects on safety accident, 2) a-type personality has interactional effect on safety accident with communication, precaution activities, and safety system. 3) physical job load has interactional effect on safety accident with precaution activities, and safety system.

Reducing the logistic cost may be accomplished by numbers of logistic management methods, but the most fundamental and essential one is the accomplishment of the consistent reverse logistics system that is the core of worker performance system, and the purpose of consistent reverse system is the treatment of logistic functions such as transportation, storage and unloading with consistent logistics, and increasing the turnover ratio is required for the improvement of the system. As the turnover ratios is increased, this paper make reverse worker performance evaluation system with lifetime value include of weight variables.

건설업계는 제조업과 특성이 달라 여러 가지 문제점이 엿보인다. 특히, 건설업 근골격계 질환에 대한 연구 및 지원은 별로 찾아볼 수가 없다. 근골격계 질환의 제조업과 건설업의 비율을 보았을 때 "2004 산업재해분석" 요양자 업종별 분포를 보면 제조업이 3,281명(79.79%)로 건설업의 63명(1.53%)보다 월등히 많은 것으로 조사되었다. 이는 미국의 사례를 보았을 때, 2007년 업종별 분포를 보면 건설업이 42,867명(26.20%), 제조업이 101,437명(36.23%)로 우리나라에 비해 건설업 근골격계 질환자가 상대적으로 많은 것으로 조사되었다. 이는 건설업에서의 근골격계 부담 작업 실태조사 등을 통하면 제도적 문제점이나, 근로자가 몰라서 질병에 이환되는 경우가 아닌가 한다. 건설업 근로자들은 건설업 특성상 근골격계 질환예방을 위한 도구를 거의 사용하지 못하고, 작업의 연속성, 지속성이 떨어지므로 부자연스럽고, 불편한 자세를 작업을 위해 수시로 반복하여 취할 수 밖에 없다. 따라서 건설업체에 중대재해를 줄이기 위한 노력 뿐 만 아니라, 열악한 건설업체의 근로자의 근골격계 질환 예방에 대한 제도적인 지원과 안전담당자 교육, 근로자에 대한 근골격계 질환 예방교육(스트레칭, 작업 자세, 동작, 근력강화, 적절한 휴식시간 부여) 등 대책이 절실히 필요하고 하겠다.

안전사고 원인에 대하여 Near-Miss Report 분석을 근거로 하여, 재해원인에 대하여 접근해 보고, 이 Data를 참고로 첨단산업에서의 재해 유형을 분석해보고, 유형에 따른 기여인자를 기존 Human-ware, Hard-ware, System-ware를 구성요소로 해서 첨단산업에서의 각각의 수행인자의 비율 분석을 통한 판단한 결과는 Human-ware와 Hard-ware 비율은 4:1로 나타났고, 첨단사업장에서의 5년간의 사고건수를 근거로 원인에 대한 수행인자의 ANOVA로 분석하여 4개인자에 대한 분산 분석을 도출하였고 이에따른 Loss와 Time과 Accident 관계와 Effect of Intervention관계와 Reason's Accident Causation Model과 Perrow's Normal Accident Theory Model를 연관시켜서 첨단산업에서의 사고이론 Model를 추출해서 첨단산업에서의 안전사고에 대한 유형을 분석해서 사고를 사전에 제거키 위한 새로운 모델을 제시하고자 한다.

The purpose of this study is to attempt a Analysis of a pointed-end Equipment Arm Safety-Accident for Fault Tree Analysis. Three major techniques were used first problem is Z-Model by which accident Analysis & prevention of a pointed-end Industry can be made, Fault Tree Analysis(FTA) bywhich quantification of a pointed-end Equipment accident Analysis can be made it 5 years in past and the third, manual-written by which minimal cut set to accident can be Identified. A example has been made of issue point a pointed-end Equipment that the Arm in loader happen to Injuries. According to the Analysis lack of safety knowledge, unsafety-behavior seem to be the primal cause of accident. Comparision of the accident cause to actual report demonstratesthat the FTA a efficient tool for Industrial Accident prevention.

It is difficult to put it into practice in that it requires bearing too much burden to draw out the planning itself in a case of large construction work. Consequently in this paper we select evaluation criteria by construction progress, classify into several categories, and regard potential danger which often occurs, as a evaluation criterion. Further step is to allow workers or collaborated companies to express their expert opinions or experiences and to encourage quality and process control and autonomous safety control by applying PSM(Process Safety Management) method using AHP(Analytic Hierarchy Process) and to development of PSIM(Process Safety Information Management) evaluation method in the construction. The reason why PSIM method should be quantitative and substantial progress is because it contributes Korean constructing companies to enhancing their safety control ability and to taking an equal stance just like developed countries, thereby strengthening their competitive edges.
