According to the increase of the requirement for the safety and environmental protection at sea, safety is a core design factor of maritime systems. Safety is defined as a perceived quality that determines to what extent the management, engineering and operation of a system is free of danger to life, property and the environment. There are many possible approaches in dealing with the safety of ships. The risk-based approach is one of the most systematic and reasonable way currently in design, operation and regulatory works for ship safety. This paper proposes a concept of total risk management for ship safety, and introduces a prototype system implemented based on this concept as a framework of design and operation of ships.

The purpose of this study is to examine the prevalence of musculoskeletal disorders and ergonomic risk factors for workers of printing business. A self-reporting survey and task analysis using video camera were performed to identify ergonomic risk factors associated with musculoskeletal disorders. We used the OWAS, RULA, and REBA methods to quantify the risk factors, and the results show that the printing business have high risk of work-related musculoskeletal disorders.

This study applied risk indexes to the disaster flow event occurred at Mt. Umyeon region in 2011. A 2D hydrodynamic model was employed to calculate flow characteristics, and the model was validated against two dam break flow problems conducted by Bellos and EU CADAM project. The model performance was shown to be satisfactory. In order to determine which index is more appropriate to assess the vulnerability of debris flow, 3 risk indexes (FII, FHR and VDI) were considered. It was found that VDI, which determines the risk level only by the velocity factor, consistently predicted the risk level corresponding to 6 because the velocity range was widely organized. However, in the case of FII and FHR, the risk was reasonably quantified due to combined consideration of significant factors of flow velocity and debris thickness. Therefore, FII and FHR are expected to be more accurate than VDI. However, two indexes still need to be improved to include major factors such as debris density or material properties.

Risk information may be one of the most important factor for worker's safe behavior because that safe behavior can be oriented by attitude based on risk information. Traditionally KAP(knowledge, attitude and practice) model was useful frame for the change of human behavior. Knowledge is formed by information through experience and education. Worker's health may be prevented by his or her own active safe behavior based on risk information. This paper is to investigate the effect of labor union on the provirion of risk information by labor union. Data for analysis is the third Korean Working Conditions Survey done by Occupational Safety and Health Research Institute in 2011. The sample size is 50,032 economic active person surveyed by household interview survey with structure questionnaire by trained interviewer. The difference of risk information provision among employees was tested by mean difference test. The level of risk information of employees of companies with labor union is higher than that with non labour union. This paper has some implication for the promotion of safe behavior of employees through risk information provision mediated by labor union. Some limitation of this study may be considered because of using the cross sectional survey data.

기존의 강우에 의한 사면붕괴 기준들은 지형학적 특성, 임상특성, 불포화 지반 조건 등을 반영하지 않아 사면 파괴 예측 지표로 활용하기에는 많은 문제점을 가지고 있다. 본 연구에서는 강우패턴, 지형학적 특성(경사, 토심), 공학적 특성(불포화 지반 특성), 임상특성(식생 뿌리에 의한 영향, 수목하중) 등을 반영할 수 있는 불포화 사면 안정성 해석 방법을 제안하였다. 뿌리보강과 수목하중을 고려하지 않는 사면의 안전율 평가는 안전율을 과다 평가하는 것으로 나타났다. 제안된 안정성 해석 방법에 의하여 강우에 의한 불포화사면의 안전율에 대한 데이터베이스를 구축하고, 이를 GIS와 연계하여 울주군 산사태위험 지정지역에 적용하여 강우에 대한 사면 위험성을 정량적으로 분석하였다. 산사태위험지역은 강우에 의한 사면의 안전율이 낮거나, 대부분 안전율 감소가 급격하게 발생한 지점의 하류에 위치하고 있음을 알 수 있다.

교통시설물의 위험요소는 안전피해의 규모 및 종류 등 복잡한 제반요소에 영향을 받기 때문에 안전개념에 기초한 분석이 요구된다. 이를 위해 본 연구에서는 교통안전시설에 대한 정성적 및 정량적 위험도분석 방법을 제시하고 이를 가치평가에 도입할 수 있는 절차를 제안하였다. 또한 정량적 분석을 위해 교통사고 데이터 및 이를 분석한 EPDO(Equivalent Property Damage Only)를 이용하여 사고빈도와 피해정도 및 사고요인별로 Event Tree를 작성하여 제시하였으며 이를 이용하여 중앙분리대 비교 1안(140cm) 및 비교 2안(127cm)에 대한 위험지수를 산정하였다.

In Korea, the occurrence and risk of similar fires are high, so setting up fire prevention measures through fire case investigation is considered the most basic measure in securing human safety. In particular, calculation of evacuation capacity in evacuation safety design of buildings is the most important factor that directly affects evacuation safety performance. However domestic standards is not consider about occupant characteristics. also the case of domestic, it has the problem that the law is partially applied when the fire safety design of buildings. Therefore, the purpose of this study is to study the current status and related regulations of the life safety code for the application of high fire risk buildings, and to analyze the difference in evacuation time through Case Study.

Job hazard analyses were conducted to assess exposure to musculoskeletal disorder (MSD) risk factors in seven workers of three dry-cleaning establishments. In accordance with the Washington State Ergonomics Rule, the analyses were performed in two separate steps: (1) observation and checklist approaches were made to identify a "caution zone job" in the seven workers' pressing operations across the three shops; and (2) detailed posture and motion analyses were undertaken to determine a "MSD hazard" in one worker's operation using a video technique. One "caution zone job" was identified and it was the pressing operation job in which five physical risk factors were found in the pressing operations. The detailed analyses confirmed that one "MSD hazard", i.e., awkward posture in shoulders, was prevalent in the pressing operations of the three dry-cleaning facilities. It would be desirable to reduce MSD risk factors including awkward shoulder posture in the dry-cleaning industry.

For various historical and technical reasons, the safety of dams has been controlled by an engineering standards-based approach, which has been developed over many years, initially for the design of new dams, but increasingly applied over the past few decades to assess the safety of existing dams. And some countries were asked for risk assessment on existing dam, which included structural, hydraulic safety of dam and social risk. Whereas other countries have developed and adapted as an additional tool to assist in decision-making for dam safety management. Dam risk analysis should need the reliability data of dam failures, the past constructed history and management records of existing dam. It is thought with risk analysis method of dams for structural safety management in domestic that suitable to use consider an event tree, fault tree and conditioning indexes method.

Objectives: This study is aimed at inquiring into the grasp of real condition of working environment and improvements by calculating the hypertension distribution consequent on job stress risk and exposure level of alleviating factors. In addition, this study is intending to estimate the hypertension distribution through socio-demographic factors and level of stressors occurring at working environment, such as high workload, low control, low support, job insecurity, long working hours, low income. Methods: This study estimated the hypertension distribution using the tertiary Korean Working Conditions Survey data, and conducted comparative analysis according to the category of individual questionnaire items using odds ratio. Result: As a result of study, it was found that in the event that working environment satisfaction is low and business & an immediate superior's attitudes are negative, the hypertension distribution was high. Particularly, it was found that physical risk factor musculoskeletal risk factor, and mental risk factor in a workplace were all increasing the hypertension distribution. Conclusions: With the aged workers' labor market participation ratio increasing, hypertension could be a major issue in the field of Occupational Safety and Health. Thus, it's necessary that the relevant employer should lower the hypertension distribution through creation of pleasant working environment and inducement of workers to improve in the relations with their superiors. As for the uppermost limit of this study, there is a limit to clarifying the mechanism of hypertension through multivariate statistics analysis because it's difficult to establish causal relationship by individual questionnaire item as the working conditions survey is made by cross-sectional study. In the follow-up research, this study is going to do research on the mechanism of hypertension through questionnaire supplementation and in-depth analysis.
