This paper is a follow-up research of 'A study on the development of Safety Management Evaluation Index for Shipping Company'. It aims to develop the evaluation items of Safety Management Index(hereafter called as 'SMI') applicable to 'Safety Advantage Point', which is suggested as the sub-index of 'Safety Management Evaluation Index' function in the preceding research and also verify their adequacy. For that purpose, firstly, the 11 evaluation items were developed after collecting the practical opinions from safety management personnels in Korean shipping companies. Secondly, the survey was carried out for the verification of the adequacy of the 11 evaluation items. And lastly, its results was analysed, whether it has statistical meanings of differences in adequacy awareness amongst safety managers grouped depending on business type(coastal, ocean-going) and business capacity(number of owned-operating ships). As a result, there was no relevance between their adequacy awareness and business type of their companies. However, a difference in their adequacy awareness existed depending on their companies' business capacity(small, medium and large sized). In conclusion, when the safety management level of shipping companies is evaluated by SMI, the same indices can be applicable to both coastal and ocean-going shipping companies by a grouping of companies' business capacity.

This paper considered the concept and characteristic OSV operation business for support the offshore plant and suggested amendment Maritime Transportation Laws, legislative proposals to solve the legal absence and to develop offshore service industry. Because Maritime Transportation Laws specialized for the carriage of passenger and goods by sea is not perfectly covered with Offshore support business in Korea. So it is necessary to make an explicit amendments for the article of Maritime Transportation Laws that founds absence of the law with the definition of terms to correspond related existed regulation reflected on the characteristic offshore support business by using OSV to develop offshore plant industry including support, service, supply, transportation etc. I expect that this paper will be a basic study to make a government policy, law, regulation to activate Offshore Service Industry in the future.

As the Korean navy's capabilities increase, it becomes increasingly necessary to develop sufficient navigational capabilities and train proficient seafarers. However, in terms of securing personnel resources, seafarers will need to be utilized more effectively due to the population decline of recent years. This paper reviews the use of civilian maritime personnel to research potential resources and uses the U.S. military sealift command as a benchmark. As a result, it has been found that it is possible to increase naval combat capability through the establishment of like a military sealift command organization to operate defense civilian support vessels. In addition, it is possible to train civilian seafarers by utilizing the current national education system through existing maritime universities. Furthermore, taking these actions will allow the ROK navy to operate its onboard ship reserve service and designated international ship system more efficiently.

해양사고의 주요 원인으로 언급되고 있는 피로요인은 장시간 소요되는 선박의 운항과정에서 발생할 수 있는 사고발생의 주된 요인이다. 이러한 피로의 유발 요인 중 하나인 음주운항으로, 이로 인한 해양사고는 대형 인명피해 뿐만 아니라 해양환경오염이라는 국가적 대재난으로 이어질 수 있다. 다행히 「해사안전법」 시행령 개정에 따라 주취운항 단속 기준 (혈중알콜농도 기준)이 기존 0.08%에서 2011년 0.05%, 2014년 0.03%로 강화됨에 따라 주취 운항의 위험성에 대한 인식은 개선되고 있으나, 최근 5년 동안 선박 음주 운항 단속 건수는 총 556건으로 나타났으며, 음주운항으로 인한 충돌, 좌초 등의 사고가 지속적으로 발생하고 있다. 본 발표에서는 음주운항이 선박운항에 미치는 영향을 알아보기 위해 선박운항 시뮬레이터 데이터 분석을 통한 음주운항 패턴 분석 결과를 소개하고자 한다.

In this study we collected various substance codes, physical and chemical properties, and hazard level of the 545 HNS which was determined earlier, and constructed the Korean HNS database including International Maritime Dangerous Goods (IMDG) codes,, informations of explosive and corrosive characteristics of HNS after reviewing of US, Japan and European Database. And also problems of present HNS Database which focused mainly on land-based environment and an absence of information for chemical and physical properties of mixed substance HNS are reported. For the efficient implementation of comprehensive HNS management system, we constructed the basic model for the HNS database in marine environment and made suggestions for improvement for the future development of HNS Database to be prepared for the marine spill accidents.

최근의 화물자동차파업사태 등으로 우리나라 물류체계의 경쟁력제고를 위한 여러 가지 논의가 진행되고 있다. 그 중에서도 환경친화적이며, 사회적 비용이 저렴한 철도화물의 수송분담율을 높여야 한다는 의견이 많이 나오고 있다. 우리나라 물류체계의 근본적인 문제점은 도로운송량의 증가보다 트럭의 공급과잉으로 트럭운송사업자의 수익은 매우 낮고, 철도, 해운 등 대량운송수단의 분담율이 낮아 전체적인 수송효율성이 낮은 것을 들 수 있다. 이러한 문제점의 해결은 트럭의 과잉공급을 억제하고, 제조업 물류비 중 46.5%를 점하고 있는 운송비용을 절감하는 것이 핵심적인 방안이라고 하겠다. 이에 본 논문에서는 철도화물의 활성화와 우리나라의 철도구조개혁의 성공적인 추진을 위해서 우리와 지형조건이 비슷하고, 1987년에 철도민영화를 시행하여 현재 16년이 경과한 일본철도화물의 현황을 분석하여, 현재까지의 문제점을 밝히고 또한 우리나라의 철도화물수송정책에 시사하는 바를 정리해 보았다. 1987년 민영화 이후 일본철도화물수송현황을 보면 영업거리, 화차대수를 포함한 수송능력 감소로 수송량은 감소하였으나, 화물수송의 장거리와 추세와 컨테이너수송량의 증가, 인력감축으로 영업성적은 전반적으로 향상되고 있다. 문제점으로는 경영면에서는 낮은 생산성 그리고 노후장비 등으로 인한 높은 설비투자비지출, 선로사용료 등의 부담 등이 지적되었다. 운영상에서는 현재 선로를 소유하지 못하여 네트워크가 부족하여 자유로운 열차편성이 어렵고, 포워더 기능이 없어 현재 전체물량의 85%를 점하는 소운송구간에서 다른 운송주체간의 수송으로 일관수송서비스에 어려움이 있으며, 직접적인 영업을 하지 못하여, 새로운 수요창출에 어려움이 있다. 이러한 문제점의 해결책으로는 먼저 정부의 인프라에 명확한 책임분담과 이에 따른 지원이 필요하다. 이와 같은 철도화물활성화의 정책수립필요성의 배경에는 철도화물수송이 효율성과 환경친화성, 높은 안전성 등 사회적 비용을 감소시키는 장점을 가지고 때문이다. 철도화물운송회사도 현재의 수송기능과 함께 포워더로서의 기능을 가져야 할 것이며, 운임인하노력과 속도향상을 위한 노력을 계속하여야 할 것이다.

The cabotage rule has been protecting the domestic industry from foreign competitions as a kind of trade barrier. In the United States, the shipbuilding industry has been maintained with the help of to the strict cabotage operations by reinforcing advantages for domestic crews and ships which are built in the U.S. For most countries, cabotage has been granted legitimacy in their coastal shipping by Low Carbon Transport in terms of economic and emergency reasons. The cabotage rule is required in the stable supply of the seafarers which rely on the legitimate maritime education. This study analyzes Korean cabotage system and the problems with regard to seafarers education. It is found that the resolution is set up the cabotage act such as Jones Act, U.S.

Vehicles transporting hazardous materials can make huge damage to people, properties and environment by traffic accidents. Therefore, transporting hazardous materials is a big issue with the cutting edge technology of communications in these days. However, despite this situation, Korean government gives limited efforts for systematic management, research and investment about hazardous materials. Accordingly, this research suggests the key path finding algorithm about management of real-time schedule and routes for vehicles transporting hazardous materials. Besides, the case study is progressed in transportation networks of Seoul in order to evaluate the reality of algorithm. Specifically, time-space network transformation is performed for time window attributes. In addition, this study proposes the techniques searching for non-dominated paths considering schedule by the multiobjective shortest path algorithm based on dynamic programming in dynamic transportation networks including multiobjective attributes.
