This paper is to analyse the necessity and development direction of the ROK's maritime security strategy white paper. To this end the paper is composed of 5 chapters titled introduction; the necessity of the ROK's maritime security strategy white paper; the ROK's actual situation in relation to maritime security strategy and cases of major advanced oceanic countries; the vision, goals, strategic tasks, and implementation system of the ROK's 'national maritime security strategy'; and conclusion. The achievement of the national marine strategic vision, such as the 'Ocean G5,' is of course possible when Korea can maintain and strengthen the maritime safety and maritime security of the people. The Sewol Ferry incident reminds us that we need a 'national maritime security strategy white paper' like the advanced marine countries. In order for the national maritime security strategy to be carried our efficiently, as in advanced oceanic countries, mere should be a dedicated department with sufficient authority and status to mobilize the cooperation of related organizations including naval-coastal cooperation. It would be good to set up a tentatively named Maritime Security Council, an organization of minister-level officials involved under the National Security Council, and an executive body composed of working-level officials from related ministries. In order to successfully carry out the national maritime security strategy for the maritime safety and maritime security of the people like the United States and the United Kingdom, we need to further strengthen our domestic cooperation and cooperation system, international cooperation, and maritime security. We have to promote the establishment and promotion of maritime security strategies by the Navy; strengthening the operational link between the Navy and the Coast Guard; strengthening the maritime surveillance capability at the national level, and promoting sharing with the private sector, etc.

해양공학에 관련된 문제를 접근하는 방법은 이론해석, 수치해석, 수리모형실험으로 정리될 수 있다. 최근 컴퓨터의 발달로 수치실험기법이 급격한 발전을 보이고 있으나, 실해역의 복잡한 환경 특성을 모두 고려한 수치모델은 아직 개발되지 못한 상태이므로 수리모형실험은 해양환경 특성을 규명하는데 있어 여전히 중요한 기법의 하나로 남아있다. (중략)

해사산업분야에서 양성평등 정책과 여성참여확대는 국제적으로 중요성을 인정받고 있다. 전세계 다양한 국가에서 선박운항, 해운 및 해양 보안등의 분야에서 여성역할을 강조하고 있으며 이를 위한 정책 및 프로그램은 확대되고 있다. UN의 지속가능한발전 목표(SDG) 5번은 양성평등으로써 UN 산하 국제기구인 (IMO)에서도 이를 구현하기 위한 활발한 여성참여 국제정책을 확대하고 장려하고 있다. 이 연구에서는 국제적으로 인정을 받고 있는 여성단체(WIMA, WISTA)의 활동과 IMO에서 운영하는 해사분야 여성 참여 정책에 대한 동향을 제시한다.

Ocean thermal energy conversion is an organic Rankine cycle that generates power using the temperature difference between surface water and deep water. This study analyzes the thermodynamic efficiency of the cycle, which strongly depends on the working fluid and the cycle configuration. Cycles studied included the classical simple Rankine cycle, Rankine cycles with an open feedwater heater and an integrated regenerator, as well as the Kalina cycle. Nine kinds of simple refrigerants and three kinds of mixed refrigerants were investigated as the working fluids in this study. Pinch-point analysis that set a constant pinch-point temperature difference was applied in the performance analysis of the cycle. Results showed that thermodynamic efficiency was best when RE245fa2 was used as the working fluid with the simple Rankine cycle, the Rankine cycles with an open feedwater heater and an integrated regenerator, and when the mixing ratio of $NH_3/H_2O$ was 0.9:0.1 in the Kalina cycle. If the Rankine cycles with an open feedwater heater, an integrated regenerator, and the Kalina cycle were used for ocean thermal energy conversion, efficiency increases could be expected to be approximately 2.0%, 1.0%, and 10.0%, respectively, compared to the simple Rankine cycle.
