선원의 직무상 재해율은 일반 산업 재해율 보다 12.6배(2018년 기준)높게 유지되고 있다. 이는 일반 산업재해와 선원의 재해 예방을 위한 근거법이 산업안전보건법과 선원법으로 이원화 되어 있고, 이에 따라 재해예방을 위한 제도가 달리 이행되고 있음이 하나의 요인으로 작용한다. 이에 선원법에 명시된 선내안전보건 관련 규정과 산업안전보건법 및 해사노동협약에서 요구하는 재해예방을 위한 규정을 비교분석하여 선원의 재해예방 방안으로 선내안전보건 관련 인명사고 통계 구축 방안에 필요한 시사점을 도출하고자 한다.

This study estimates the demands for safety training courses with reference to research on safety training records, seafarer statistics, target groups for safety training, expiry dates of existing safety courses, seafarer employment rates, the retirement age, etc. These results are compared with the seating capacity of the maritime training institute to analyze the anticipated increase in and convergence of demand can be accommodated. The average annual safety training needs for the next five years according to the Seafarers Act include approximately 10,444 people, and the proper annual seating capacity of the maritime training institute is approximately 7,280 people at present. Thus, in order to respond to an increasing demand for safety training, it is necessary to expand the capacity of the safety training facility.

Seafarers are exposed to various unpredictable maritime risks due to the spatial specificity of the working environment of the sea; thus, sufficient compensation for injured crewmembers is needed. However, Korea does not provide such compensation. Therefore, this study attempted to examine the Maritime Labor Act and the Industrial Accident Insurance Act of Germany, an advanced European social insurance country, and derive implications compared to Korea. First, we investigated how compensations are managed by a public institution in Germany and by shipowners in Korea. Second, regarding the contents of accident compensation, Germany does not only provide continuous treatment and care through various support systems, but also operates various programs to enable a return to ship work. In contrast, Korea has a temporary compensation system that allows shipowners to avoid liability for accident compensation, which is disadvantageous to shipwrecked seafarers. Finally, in Germany, workers' compensation insurance is public, judged considering the origin of work, whereas in Korea, it is determined by shipowners or insurance companies. Therefore, it is necessary to establish a public institution in charge of crew accident compensation to ensure proper compensation for crewmembers in Korea and to improve the Seafarers Act or system to provide compensation for additional medical care, disability pension, and rehabilitation benefits.

Currently, the dose distribution calculation used by commercial treatment planning systems (TPSs) for high-dose rate (HDR) brachytherapy is derived from point and line source approximation method recommended by AAPM Task Group 43 (TG-43). However, the study of Monte Carlo (MC) simulation is required in order to assess the accuracy of dose calculation around three-dimensional Ir-192 source. In this study, geometry factor was calculated using segmented sources integration method by dividing microSelectron HDR Ir-192 source into smaller parts. The Monte Carlo code (MCNPX 2.5.0) was used to calculate the dose rate $\dot{D}(r,\theta)$ at a point ($r,\theta$) away from a HDR Ir-192 source in spherical water phantom with 30 cm diameter. Finally, anisotropy function and radial dose function were calculated from obtained results. The obtained geometry factor was compared with that calculated from line source approximation. Similarly, obtained anisotropy function and radial dose function were compared with those derived from MCPT results by Williamson. The geometry factor calculated from segmented sources integration method and line source approximation was within 0.2% for $r{\geq}0.5$ cm and 1.33% for r=0.1 cm, respectively. The relative-root mean square error (R-RMSE) of anisotropy function obtained by this study and Williamson was 2.33% for r=0.25 cm and within 1% for r>0.5 cm, respectively. The R-RMSE of radial dose function was 0.46% at radial distance from 0.1 to 14.0 cm. The geometry factor acquired from segmented sources integration method and line source approximation was in good agreement for $r{\geq}0.1$ cm. However, application of segmented sources integration method seems to be valid, since this method using three-dimensional Ir-192 source provides more realistic geometry factor. The anisotropy function and radial dose function estimated from MCNPX in this study and MCPT by Williamson are in good agreement within uncertainty of Monte Carlo codes except at radial distance of r=0.25 cm. It is expected that Monte Carlo code used in this study could be applied to other sources utilized for brachytherapy.

330MWt 출력의 신형 원자로인 SMART(System integrated Mod씰w Advanced ReacTor)가 전기 생산뿐만 아니라 해수의 담수화를 위한 에너지 공급을 위해 한국원자력연구소에 의해 개발되고 있다. SMART의 원자로 압력용기에서의 중성자 조사량을 기존의 각분할법 코드 대신에 몬데칼로 수송 코드인 MCNP-4A를 이용하여 평가하였다. MCNP-4A에 의한 몬데 칼로 모사는 각분할법에 비해 핵 단면적 자료, 선원항, 그리고 기하학적 모델링의 문제로부터 야기되는 불확실성을 감소시킬 수 있을 뿐만 아니라 초기 개념 설계 단계에서 상세 노심 출력 분포 자료에 의존하지 않고 선원항을 평가할 수 있는 장점이 있다. 본 연구에서는 원자로 압력 용기 내부의 원자로 노심 및 다른 구조물을 포함하는 전체 원자로 구조에 대하여 몬테 칼로 모사를 적용하였다. 1단계에서는 임계도 계산에 의해 선원항으로 이용되는 원자로 노심내의 열 출력 분포를 평가하고, 2단계에서는 노심내의 열 출력 분포를 고정 선원으로 이용하여 압력 용기에서의 중성자 조사량을평가하였다. 그 결과 SMART 압력용기의 중성자 조사량은 규제 요건을 만족하는 것으로 나타났다.

In Korea a crew employment right is only allowed to shipowners and cooperative business between ship management and crew management company is not allowed. It is anticipated that overseas ship management companies' entry into Korean ship management markets will weaken Korean ship management companies' competitiveness. Therefore, it is necessary to amend crew management regulation. The purpose of this study is to investigate the situation of Korean ship management industry and to suggest the scheme for strengthening its competitiveness. The result of this study will contribute to the growth of the Korean ship management industry and enhance their business scope internationally.
