예부선의 운항은 일반적으로 자항능력을 갖추고 있지 못한 부선과 예인선을 결합하여 운항하는 해상운송의 한 형태로 해양안 전심판원이 해마다 발행하는 재결사례집에 실린 재결을 분석하여보면 지난 5년간의 해양사고 6백여 건 중 예인선은 65척, 부선은 총 69척 에서 사고가 발생한 것으로 나타났다. 본 논문은 예부선 사고의 저감 대책을 제안하기 위하여, 예부선의 운항 형태와 운항현황을 알아보 고, 재결에 나타난 주요 사고 형태별 사고방지 교훈 내용을 분석하였다. 이를 통하여 인적요소가 해양사고의 원인으로서 차지하는 비율이 크다는 것을 확인할 수 있었다. 또한 본 연구는 사고방지를 위하여 예부선 운항자들에 대한 관련 내용의 효율적인 홍보와 교육을 위한 방 안으로서 예부선 협회를 통해 홍보하는 방안과 한국해양수산연수원의 예인선직무교육에 교육자료 형태로 제공하는 방안, 한국해운조합 을 통해 홍보물을 배포하는 방법 등을 제안하였다. 이러한 연구 결과는 예부선 사고에서 나타난 사고방지 교훈을 본 연구에서 제안한 홍 보방식을 통하여 효과적인 교육을 실현하여 예부선 사고의 저감에 활용될 것으로 기대된다.
PURPOSES : The objective was to develop the advanced method which could not explain each observation’s specific characteristic in the present negative binomial method that results in under-estimation of the standard error(t-value inflation) and affects the confidence of whole derived results. METHODS : This study dealt with traffic accidents occurring within interchange segment on highway main line with RPNB(Random Parameter Negative Binomial) method that enables to take account of heterogeneity. RESULTS : As a result, AADT and lighting installation type on the road were revealed to have random parameter and in terms of other geometric variables, all were derived as fixed parameter(same effect on every segment). Also, marginal effects were adapted to analyze the relative effects on traffic accidents. CONCLUSIONS : This study proves that RPNB method which considers each observation’s specific characteristics is better fitted to the accident data with geometrics. Thus, it is recommended that RPNB model or other methods which could consider the heterogeneity needs to be adapted in accident analysis.
The purpose of this study was to reduce safety accidents among food employees in contracted foodservice management companies, and to help provide high-quality foodservice and assistance. For this, a survey on the different opinions of workplace safety and education by employment type and employee perceptions of environment and safety at foodservice operations was carried out. The analysis showed that among the workers many women were irregular employees. For average age, between 40 and 49 was the most frequent, and for work duration, under one year was highest. Both regular employees and irregular employees deemed "enough staff" as the most major factor for good foodservice. The regular employees and irregular employees thought "high indoor temperatures and poor ventilation in the kitchen area" and "bad work cooperation between employees" as the main problems of foodservice operations, respectively. For satisfaction with the efficiency of foodservice production system, irregular employees had higher satisfaction than regular employees. Both regular employees and irregular employees thought "the number of foodservice employees" as the foremost improvement for safety-accident prevention and work-stress improvements. Regular employees, more than irregular employees, thought improvements in foodservice production systems would have a large affect on safety-accident prevention and work-stress improvements of food workers. Both regular employees and irregular employees thought "foodservice employees` safety consciousness" was an important part of safety-accident prevention. Likewise, they responded that "lectures by the person in charge of safety education" was a good methods of safety education, and "once a month" was the best period for safety education. For the difference in perceptions of environment and safety in foodservice systems, regular employees had a higher perception of safety than irregular employees.
The studies on semiconductor industrial accident in korea have been focused on the frequencies of each type of safety management employee, characteristics, cause and unsafe conditions, acts and so on Those attributes of semiconductor industrial accidents
The modem industrial society is developing while growing more diverse and gigantic. Accordingly, occupational injuries or accidents can be caused in various situations, not just in the limited range of workplaces but also in the surroundings, and interest has increased in the prevention of occupational accidents with respect to occupational health and safety, and environment. Thus, this thesis will consider 4MlE (Man, Machine, Method, Material, Environment) as the fundamental causes of accidents and introduce a model of system in which the output of the process control system is replaced by accidents with its input by 4M1E. Furthermore, it will demonstrate how occupational hazardousness can be measured, whereby it can also be rated, by examining the relationship between 4M1E and types of accident in terms of the categories of severity, frequency, and detectability, based on the application of the model to the framework of FMEA.
