  • 최근 경제자유구역에 관한 법률이 통과되면서 인천, 부산, 광양항이 그 첫 번째 대상지로 지정될 예정이다. 그러나 경제자유구역 제도는 동북아 비즈니스 중심국가 상업의 일환으로 매우 중요한 사업이지만 수도권과 대도시 중심의 지역간 불균형발전 초래, 유사한 제도인 자유무역지역이나 관세 자유지역, 국제자유도시, 외국인투자유치지역 등과의 중복성으로 자칫 비효율적인 투자가 우려되고 있다. 본 연구는 군산항 인근을 경제자유구역으로 지정할 필요성과 잠재력을 제시하고, 경제자유구역제도의 발전방향과 유사지역과의 통합정보 관리시스템 도입방안을 제시하고자 한다.

  • This paper is intended to suggest benchmarking ascension for the Gwangyang Port as a hub for international logistics. Most countries that seek to join. and lead, the global trading system as they work to develop production and logistics systems that establish a reputation for leadership in international logistics. Our focus in this research is on the Gwangyang Port and whether Gwangyang Port is capable of carving out a competitive niche as a hub of international logistics. Our analysis is based on comparison and analysis with benchmark port developments around the world. As proposals to promote and activate Gwangyang Port as a hub for international logistics, we recommended in this paper several benchmarks. First, Gwangyang Port FTZ must strengthen the incentive system for tenant companies and providing an inducement for new global companies. Second, Gwangyang Port needs to moderation of regulation on the investment tenant companies and strengthening one-stop service. Third, it is required to stabilize labor and management relationship and securing of flexibility of labor market. Lastly, Gwangyang Port must strengthen mutual interaction of Free Economic Zone (FEZ), Customs Free Zone(CFZ) and Free trade Zone(FTZ) in Korea.

  • 항로추종성능은 자율운항선박(MASS)의 중요한 자율제어기능 중 하나이다. 이는 선박의 안전성을 보장하기 위해 중요하며, 자율운항선박의 설계 단계에서 사전 평가가 필수적이다. 본 연구는 자율운항선박의 항로추종성능 평가를 위한 전산유체역학(CFD) 모델과 LOS 알고리즘 연계 방안을 제안한다. 먼저, 자율운항선박의 정수 중 거리 이탈 편차를 이용한 항로 추종 성능 평가 모델 개발에 관하여 기술했다. 먼저, 항로 추종을 수행하는 선박 주변의 난류 흐름은 비압축성 뉴턴 유체의 가정하에 비정상 RANS(Reynolds Averaged Navier-Stokes) 법을 이용하여 수치적으로 계산되었다. 중첩격자계법을 CFD 모델에 적용함으로써 거리 이탈 편차를 이용하는 LOS(Line-of-Sight) 가이던스 알고리즘에 의한 타의 회전 및 이에 따른 선체의 6 자유도 움직임을 CFD 환경에서 구현하였다. 개발된 자유 항주 선박 CFD 모델을 이용하여 항로 추종 시뮬레이션 평가 결과, 설정된 항로에서 선박의 정수 중 항로 추종 제어는 파도, 조류, 및 바람과 같은 외부 교란의 부재로 LOS 알고리즘에 의한 우현/좌현 측 변침뿐만 아니라 직진 경로의 추종도 성공적으로 수행됨을 확인하였다. 선체, 프로펠러, 타의 복잡한 상호작용을 정도 높게 해석할 수 있는 자유 항주 선박 CFD 모델과 LOS 알고리즘의 결합은 자율운항선박의 항로 추종 성능 평가를 정량적으로 평가하는 데 기여할 것으로 기대된다.

  • The Russian government enacted the 'Federal Law on the Free Port of Vladivostok' to improve the medical industry in the Far East in 2015. As a result, Korean medical institutions are increasingly interested in advancing into Free Port of Vladivostok. Increased demand for high-quality Korean medical services from Russian patients and the active government policy direction of the Russian government serve as strengths and opportunities for advancing into Free Port of Vladivostok. On the other hand, the legal imperfections caused by the delay in the establishment of sub-regulations for Federal Law on the Free Port of Vladivostok and the low reliability of the Russian government are both weaknesses and threats. Therefore, Korean medical institutions will need to carefully consider the timing of advancing into Free Port of Vladivostok by closely monitoring the process of establishing the sub-regulations of Federal Law on the Free Port of Vladivostok. And it is the most realistic model for Korean medical institutions to establish 'Professional clinic model linked with health screenings(1st stage model)'. The Korean government needs to conclude a 'MOU for Cooperation on Health and Medical Care between Korea and Russia' with the Russian government and should also carry out the 'Korean Minnesota Project'.

  • Currently, the adoption of FTZ(Free Trade Zone) has been recognized as one of the most important strategies for becoming hub port in the world. For this reason, various policies for successful implementation and adoption of FTZ have been presented, and a special law related this FTZ was actually built in 1999. In the mean time, a port logistics industry is deeply related to the successful implementation of FTZ. However, although many research about FTZ have been conducted, there have been little previous studies about port logistics firms and FTZ. Thus, the aim of this study is to investigate a market structure of firms related to Port Logistics effectively and to analyze the perception of these firms about FTZ in Busan.

  • The purpose of this study is to suggest the new port development concepts in relation to the Mokpo port development. To analysis, we examine the relationship between the trade volumes which the port have and the capacities of the port facilities with 8 Korean seaport data. As a result of analysis, the trade volumes of port were found to be the major factors positively influencing the capacities of the port facilities in Korean ports. This findings shows that Mokpo port which trying to increase the trade volumes should have the new alternatives for Mokpo regional development. The new alternatives on the Mokpo Port's development are the model which constructing the Free Trade Zone(FTZ) and port city.

  • A numerical method for simulations of inviscid incompressible flow fields around a ship advancing on the free surface is developed. A body fitted coordinate system, generated by numerically solving elliptic type partial differential equations is used to conform the ship and free surface configurations. Three dimensional Euler equations transformed to the non-staggered body fitted coordinate system are discretised by finite difference method. Time and spatial derivatives are discretised by forward and centered differencings, respectively, and artificial dissipations are added to discretised convection terms for improvements of numerical stability. At each time steps, free surface elevations are recomputed to satisfy nonlinear free surface conditions. Poisson equations for pressure field are solved iteratively and the velocity field for next time step is extrapolated. To verify the developed numerical method, flow fields around a Wigley model are simulated(Fn=0.250-0.408) and compared with experimental data to show good agreements.

  • For the calculation of the free-surface elevation, a new finite difference scheme is studied where the third derivative term for the wave elevation is artificially added in the Eulerian expression of the free-surface boundary condition. The paper presents a comparative analysis with simulations performed by the classical MAC method. More schematic computations are carried out by changing the submergence-depth and angle-of-attack. The present study shows that this new method is very efficient for the simulation of free-surface elevation around the trailing edge.

  • Incheon Port urgently requires designation of a free trade zone to pursue development linked with the port hinterland while promoting continuous growth of the port. This study aims to evaluate the optimal location and derive policy implications for the designation of a free trade zone and analyzed factors property divided by groups. This study used the Consistent Fuzzy Preference Relation (CFPR) analysis technique to derive a practical construction direction by quantifying and evaluating linguistic measures. As a result, the Incheon New Port hinterland showed the highest location competitiveness among the four candidate areas of Incheon New Port hinterland, Aam Logistics Complex 2, North Port hinterland, and Gyeongin Port hinterland. Among the eight evaluation factors consisting of qualitative and quantitative factors, the Incheon New Port hinterland ranked no. 1 in all the four qualitative factors and one quantitative factor and received the highest total score. Also, Group 1 presented 'possibility to attract tenant companies' as first. Group 2 was 'complex size' and Group 3 was also 'possibility to attract tenant companies'. This study has the implication for suggesting the factors and evaluation structure of Free Trade Zone. Future research requires detailed empirical studies, such as expanding the subject of study or selecting factors that reflect the interests of each group.
