The powered purse seine fishery is an important fishery accounting for 19.4% of adjacent water fishery production in Korea, and the commercial fishing is associated with high rate of fatal and non-fatal occupational injury. The hazard analysis for the fishermen’s safety of offshore large powered purse seiner was conducted to serve as a basic data for improving the healthy and safe working environment of fishermen using fishermen’s occupational accidents of the national federation of fisheries cooperatives (NFFC) in 2013 (n=583). As a result, the occupational accident occurrence rate of this fishery was 182.6‰ in all industries 30.9 times the rate of that. In addition, death and missing rate was found to have a very serious level management to 25.1‱ in all industries of death of 17.5 times. The accident occurred in 72.3 to 85.8% was happened at sea. The others, slipping and struck by object etc occurred more frequently in order in the frequency of accident occurrence pattern. However, the occurrence rate of death and missing did not match the frequency of accident pattern. In other words, slipping occurred frequently higher while death and missing risk was not high. And the contact with fishing gear and fall in the waters was low while death and missing risk was high. The results are expected to contribute for identification and assessment of safety hazard occurred in offshore large powered purse seiners.

In the safety assessment of the geological disposal system of the radioactive wastes, the abnormal scenarios, in which the system is impacted by the abnormal events, need to be considered in addition to the reference scenario. In this study, characterization and prediction of well intrusion as one of the abnormal events which will impact the disposal system were conducted probabilistically and statistically for the safety assessment. The domestic well development data were analyzed, and the prediction methodologies of the well intrusion were suggested with a computation example. From the results, the annual well development rate per unit area in Korea was about 0.8 well/yr/km2 in the conservative point of view. Considering the area of the overall disposal system which is about 1.5 km2, the annual well development rate within the disposal system could be 1.2 well/yr. That is, it could be expected that more than one well would be installed within the disposal system every year after the institutional management period. From the statistical analysis, the probabilistic distribution of the well depth followed the log-normal distribution with 3.0363 m of mean value and 1.1467 m of standard deviation. This study will be followed by the study about the impacts of the well intrusion on the geological disposal system, and the both studies will contribute to the increased reliability of safety assessment.

New e-navigation strains require new technologies, new infrastructures and new organizational structures on bridge, on shore as well as in the cloud. Suitable engineering and safety/risk assessment methods facilitate these efforts. Understanding maritime transportation as a sociotechnical system allows the application of system-engineering methods. Formal, simulation based and in situ verification and validation of e-navigation technologies are important methods to obtain system safety and reliability. The modelling and simulation toolset HAGGIS provides methods for system specification and formal risk analysis. It provides a modelling framework for processes, fault trees and generic hazard specification and a physical world and maritime traffic simulation system. HAGGIS is accompanied by the physical test bed LABSKAUS which implements a physical test bed. The test bed provides reference ports and waterways in combination with an experimental Vessel Traffic Services (VTS) system and a mobile integrated bridge: This enables in situ experiments for technological evaluation, testing, ground research and demonstration. This paper describes an integrated seamless approach for developing new e-navigation technologies starting with simulation based assessment and ending in physical real world demonstrations.

Hydrogen energy is expanding in range for civil use together with development of pollution-free power sources recently, and it is judged that the use of hydrogen will increase more as a part of carbon dioxide reduction measures according to the Climatic Change Convention. Especially, it is thought that the securement of safety of the used dispenser will be the biggest obstacle in the use of high-pressure hydrogen because the hydrogen station is operated in a high pressure. This study found risks in the process and problems on operation by making use of HAZOP(6 kinds), a qualitative safety evaluation technique, and FMEA(5 kinds), a fault mode effect analysis, for the hydrogen charging system at a hydrogen gas station, derived 6 risk factors from HAZOP and 5 risk factors from FMEA, and prepared measures for it.

The occupational health and safety accidents were continuously increased during handling, usage and manufacturing the chemical materials according to increase of small and medium sized enterprises in domestic industries. These accidents mainly resulted from insufficient occupational health and safety management and deteriorative facilities and focused on corresponding operation to minimize the damage of accidents after occurrence. But, it was required that we grasped the occurrence causes of occupational health and safety risk in handling, usage and manufacturing the chemical materials and develop the adequate corresponding operation and system according to the possible occurrence of occupational health and safety risk. This study deals with the development of risk assessment model to derive the risk and important risk of occupational health and safety and then help to construct the self-controlled occupational health and safety system for small and medium sized enterprises handling the chemical materials.

Seismic intensity deduced from instrumental data has been evaluated using the empirical relationship between intensity and peak ground acceleration (PGA) during an earthquake. The Japan Meteorological Agency (JMA) developed a seismic intensity meter, which can estimate the real-time seismic intensity from seismic motions observed at a local site to evaluate the damage during the earthquake more correctly. This paper proposes a practical application of the JMA intensity to dams during the 2013 earthquake in Yeongcheon, Korea. In the present paper, seismic intensity was estimated from the relationships between accelerations observed at Yeongcheon Dam. Estimated seismic intensities were in the range of 0 to 3, which was verified from the displacements of dams and the variation of the ground water level observed at Yeongcheon dam during the earthquake. The JMA intensity, which is determined by considering the frequency, duration of cyclic loading, etc., was 0 (zero) and there was no damage to Yeoncheon dam during the earthquake.

본 연구의 목적은 가정 내 안전성 평가도구에 대해 알아보고 노인에게 적용해봄으로써 노인의 가정환경 평가를 소개하고, 향후 국내에서의 적극적인 사용을 제안하기 위한 것이다. 가정 내 안정성 평가도구 중 Safety Assessment Scale(SAS)는 다른 평가도구에 비해 비교적 문항수가 적고, 실시 방법이 간단한 장점을 가지고 있다. 본 연구에서는 강원도 원주시에 거주하는 노인 두 명의 가정을 방문하여 SAS 평가를 하였다. 두 대상자 모두 독거노인으로 연령, 인지기능, 한국판 간이 정신 상태 검사(Mini Mental State Examination – Korea; MMSE-K)점수는 유사하였다. SAS 평가결과는 비슷한 인지 수준 의 대상자라고 하더라도, SAS의 점수에는 10점의 차이가 있었다. 대상자 1의 경우 대상자 2에 비해 점수가 더 높았고, 즉 이것은 위험이 크다고 해석할 수 있었다. 특히 낙상 및 안전사고, 영양 상태의 위험이 컸고 이러한 항목의 중재 및 교육이 필요하였다. 앞으로 작업치료 영역에서 노인을 대상으로 한 가정 내 환경에서의 안전성 평가의 중요성은 점점 더 부각될 것으로 보인다. 대상자의 안전한 가정 내 생활을 위한 중재 수립, 대상자 교육, 나아가 대상자의 가정환경 수정을 하기 위한 평가도구의 하나로서 SAS의 적용을 고려해 볼 수 있을 것이다.

본 연구에서는 대정해상풍력단지 설치 해역과 인근수역을 이용하는 선박교통량과 해상교통흐름의 패턴을 분석하고 단지 조성 후 합리적인 대체통항로 지정에 따른 교통량을 예측하였다. 또한 예측된 교통량을 근거하여 통항로별 통항안전성을 평가하고 검토함으로써 선박의 안전운항에 필요한 제반조건 및 대책을 제시하였다. 풍력단지 설치 해역과 인근수역의 해상교통흐름 패턴을 분석한 결과 총 8가지의 교통흐름으로 분류되었고, 연간 교통량은 8,975 척으로 예측되었다. 이를 근거로 단지 조성 후 4가지의 대체 통항로 지정에 따른 교통량을 예측하였다. 예측된 교통량과 SSPA의 동력선충돌모델을 이용하여 통항안전성을 평가한 결과 충돌 및 침로이탈확률에 관한 국내 안전기준 10-4 이하를 만족하므로 계획된 대체통항로가 유용함을 확인하였다.

본 연구에서는 울산항 E 집단정박지를 이용하는 대표적인 8척의 선박에 대한 단묘박 상태에서의 묘박안전성을 앵커와 앵커체인의 파주력과 바람, 파랑 및 조류에 따른 외력으로 상호 비교하여 평가하고, 주묘 발생이 가능한 최소 한계 외력을 분석하고자 한다. 파주력은 해저저질과 실제 앵커 의장수를 반영했고, 선체에 작용하는 외력은 만재와 경하상태별로 풍압면적과 수면하부 침하면적을 조사하여 각 상태별로 선체에 작용하는 풍압력, 유압력 및 파랑 표류력을 산출하였다. 단묘박 상태에서의 주묘 한계 외력에 대한 분석 결과 선박의 종류, 규모 및 적재 상태별로 다소 차이는 있으나 조류 2 knots 조건 하에서 일반화물선은 풍속 15 m/s 이상, 유류운반선은 풍속 13 m/s 이상이면 주묘가 발생할 수 있음이 확인되었다.

본 연구에서는 선박항행이 허용되어 선박이 다니는 공유수면의 일정부분을 바다골재채취구역으로 하는 골재채취업에 대한 법적근거, 해상교통안전진단제도와 해역이용 협의 및 평가제도의 평가에 대한 중복성 및 양 제도간 적용 우선순위 등의 문제점으로 사업자에게 시간적·경제적 부담을 가중시키고 있으므로, 문제점 해결을 위한 개선방안을 제시하였다. 해양수산부에서 해사안전법과 해양환경관리법을 담당하고 있으므로 업무 협조체계를 유지하여 각각의 제도 평가위원회에 상호 전문가를 포함하는 방안과, 법률을 개정하여 근본적으로 해결하는 방안이 있다. 이를 통하여 해양에서 발생하는 사고의 개연성을 감소시키고 해양환경을 보호하는 방법이 될 것이다.

Prevention of the disasters is the best welfare to workers and it brings the growth and stability of an enterprise, finally uplifts the national competitiveness. Because small-scale businesses do not have safety and health managers, the government provides a wide range of safety and health management supports to small-scale businesses. However despite of this government's effort, the industrial accident rate of small-scale businesses does not decline, which is mainly because the projects are not differentiated according to the risk level of individual business. Therefore, this paper aims to obtain implications concerning a plan to conduct a reliable assessment of education through a safety job assessment, and to build a framework which may improve a technical area through the AHP analysis.
