  • Concerns related to the safety of bulk carriers we, most of all, the increasing number of bulk carrier accidents which amount to 425 during last 20 years; half of them are totally lost. A number of bulk tarriers are still missing. Bulk carrier safety has become an international issue since 1995. The International Maritime Organization (IMO) embarked on the legislation as a countermeasure to the increasing number of the bulk carrier accidents. The IMO discussed in the safety of bulk carriers including the strength of transverse watertight bulkheads, especially when the ship carries high density cargoes and the damage stability of bulk carriers in the flooded condition. In this study, statistics and causes of accidents of bulk carriers are analyzed in order to identify special features of bulk carrier accident and causes of the casualty. This study examines certain cases of hull collapses and severence which resulted in sinking to infer possible causes of missing ships.

  • 교통사고는 다양한 요인으로 인해 발생한다. 그 중에는 교통사고가 발생할 당시의 기상상태가 있다. 기상상태에 따라 교통사고로 인해 발생하는 사망자의 비율은 차이가 있다. 교통사고로 인한 사망자의 수를 줄이려면 기상 상태에 따라 발생될 교통사고 발생 수를 예측 하는 것이 필요하다. 본 논문은 기상 상태에 따른 교통사고 발생 빈도수를 예측하는 모델링을 제안한다. 예측 모델링의 이론으로는 마코프 프로세스를 적용하였다. 제안된 모델링에 실제 데이터를 적용하여 교통사고 발생 수를 예측 하였고, 실제 발생 수와 비교하였다. 본 논문은 기상 변화에 따른 교통사고 정책수립에 도움을 줄 것이다.

  • PURPOSES : There are many recently constructed roundabouts in Jeollabuk-do province. This study analyzed how roundabouts reduce the risk of accidents and improve safety in the province. METHODS : This study analyzed safety improvement at roundabouts by using an accident prediction model that uses an Empirical Bayes method based on negative binomial distribution. RESULTS : The results of our analysis model showed that the total number of accidents decreased from 130 to 51. Roundabouts also decreased casualties; the number of casualties decreased from 7 to 0 and the seriously wounded from 87 to 16. The effectiveness of accident reduction as analyzed by the accident prediction model with the Empirical Bayes method was 60%. CONCLUSIONS : The construction of roundabouts can bring about a reduction in the number of accidents and casualties, and make intersections safer.

  • As people make efforts on accident prevention, the number of accidents has decreased over the years, however the number of fatal major industry accidents has rather increased, which resulted in the increase of the number of deaths in total. Under these conditions, there is an attempt to introduce and perform the safety vocational education system as a means for preventing major industry accidents. Therefore, in this paper, we analyse vocational education of manufacturing industry from the safety's point of view and suggest the efficient techniques measuring and managing each safety management. Proposed techniques show that the specification on safety determines weight through the managers of firms and each process is suggested by using SN ratio.

  • PURPOSES : This study deals with the pedestrian accidents in case of Cheongju. The goals are to develop the pedestrian accident model. METHODS : To analyze the accident, count data models, truncated count data models and Tobit regression models are utilized in this study. The dependent variable is the number of accident. Independent variables are traffic volume, intersection geometric structure and the transportation facility. RESULTS : The main results are as follows. First, Tobit model was judged to be more appropriate model than other models. Also, these models were analyzed to be statistically significant. Second, such the main variables related to accidents as traffic volume, pedestrian volume, number of Entry/exit, number of crosswalk and bus stop were adopted in the above model. CONCLUSIONS : The optimal model for pedestrian accidents is evaluated to be Tobit model.

  • The nation is turning into aging society, and safety accidents among elderly people are on the rise. When death roll caused by safety accidents was investigated, senior citizens who died from safety accidents outnumbered the other age groups who died for the same reason. The most common cause of death was traffic accidents, followed by suicide and a hurt from a fall, and Korea rated first among OECD member nations in death roll by traffic accidents. Aging brings a lot of physical changes to elderly people, and they are often likely to be involved in accidents such as a hurt from a fall due to degenerated sensory organs like hearing and eyesight and deteriorated motor skills. Unsafe social facilities also have them face a lot of accidents, including fracture and death, and such accidents take place even at home that is usually considered safe, or are triggered by things of daily use. As a result of comparing every age group's death roll by safety accidents, the number of senior citizens who died from safety accidents was far higher than that of the other age groups who died for the same reason in every accident field. In aging society, a sharp increase in the elderly population and ensuing safety accidents are expected to pose a serious threat to national economy, and diverse efforts should be put into tacking this problem. For instance, safety education should be provided to people in general including senior citizens on a regular basis, and more safety facilities should be prepared. Besides, safety equipment should be developed.

  • Background: The death rate of workers due to industrial accidents in South Korea (3.61 persons in 2017) is higher than the Organization for Economic Cooperation and Development average (2.43) and the fifth highest among Organization for Economic Cooperation and Development member countries. Although the pandemic of novel coronavirus (COVID-19) has changed, the socioeconomic aspects of Korean society, the number of Koreans suffering accidents and the number of deaths in 2020 have increased. It is necessary to take measures to prevent accidents and make comprehensive efforts to return to work. This study proposes research questions about the effect of workers' positive perception on whether to work after accidents and the impact of the experience of rehabilitation services on the return to work. Methods: This research performed a panel logistic regression analysis using data on workers' compensation insurance in Korea for two years (2018-2019). Results: This research finds that workers' positive perceptions of workability and life satisfaction contributed affirmatively to their re-employment. Several factors related to employment (e.g., work period, the number of job qualifications) also positively affect their return to work. However, the experience of rehabilitation services did not have a significant effect on re-employment. The variables of their health conditions (e.g., disability grade, feelings of health problems, age) negatively influenced their return to jobs. Conclusion: These results suggest the importance of workers' mental recovery and the need to innovate rehabilitation services for their employment. Positive thinking and self-rehabilitation could be critical for workers, parallel with social welfare policies.

  • Despite the accident rate for fishing vessels accounts for 70% of all maritime accidents, few studies on such accidents have been done and most of the them mainly focus on causes and mitigation policies to reduce that accident rate. Thus, this risk analysis on sea accidents is the first to be performed for the successful and efficient implementation of accident reducing measures. In risk analysis, risk is calculated based on the combination of frequency and the consequence of an accident, and is usually expressed as a single number. However, there exists uncertainty in the risk calculation process if one uses a limited number of data for analysis. Therefore, in the study we propose a probabilistic simulation method to forecast risk not as a single number, but in a range of possible risk values. For the capability of the proposed method, using the criteria with the ALARP region, we show the possible risk values spanning across the different risk regions, whereas the single risk value calculated from the existing method lies in one of the risk regions. Therefore, a decision maker could employ appropriate risk mitigation options to handle the risks lying in different regions. For this study, we used fishing vessel accident data from 1988 to 2016.

  • 본 연구는 경북도내에서 발생한 4년간의 교통사고 자료를 대상으로 Empirical Bayes (EB) 방법을 이용하여 예상사고건수를 예측하였다. 경북도내 각 군과 시 지역의 교통사고는 대물피해환산법을 적용하여 심각도를 반영하였으며, EB 방법을 적용하기 위해 군집분석을 통해 유사한 지역을 선정하였고, 선정된 유사지역을 대상으로각 지역별 안전성능함수(SPF)를 도출하였다. 실제 사고건수와의 근원적인 확률분포를 일치시키기 위해 과분산 파라메타를 산출하였으며, 지역별 교통특성을 반영하기 위해 가중치를 적용하여 예상 사고건수를 예측하였다. 분석 결과 김천시, 영천시, 칠곡군 순으로 가장 높은 사고건수가 예상되는 반면, 군위군이 가장 낮은 사고건수가 발생할 것으로 예측되었다.
