우리나라에서는 최근 인천대교를 비롯하여 북항대교, 광양대교, 울산대교 등과 같이 항행로 상에 해상교량을 건설 중이거나 계획하고 있다. 그러나 이러한 해상교량 건설시에 정형화된 기준 및 법령이 미흡하여 해상교량 건설을 위한 사전 평가에 이해 관계자들이 합의를 하지 못하는 중 많은 시간과 경비를 낭비하고 있는 실정이다. 이 연구는 해운선진국 증 해상교량을 많이 건설하였고 건설 전 평가를 해 본 경험이 있는 일본의 관련 기준과 법령을 조사 분석하여 우리나라에 적절한 해상교량 건설 관련 기준 및 법령 작성에 도움을 주고자 한다.

The Korean Government is planning to build commercial districts and amenities for the major port such as Busan, Gwangyang, and Incheon in order to activate the hinterland in each port. The foreign ports in Germany, Japan and China is competing with Korean ports are developing the commercial districts and amenities of seaport hinterland in order to support urban functions. The purpose of this study is to predict the demand for the facility of commercial districts and amenities planned in the Gwangyang seaport hinterland, then to propose its utilization plans. By the demand forecasting, the districts and amenities need to be full of office, accommodation and commercial facilities, etc. In addition, the districts need to be developed gradually for the target of 2035, considering the demand growth. Leasing out the property to secular tenants, it needs to charge rent for profits of port authority. Therefore, it is required to revise the National Ports Act for the private agency to take part in building the facilities of the commercial districts and amenities.

최근, 자유수면을 갖는 비압축성 유체의 해석을 위해 Hirt and Nichols(1981)가 제안한 VOF법이 자유수면을 취급하는 많은 학문분야에서 활발히 활용되고 있다. 특히, 일본에서 잠제에 의한 쇄파해석에 암전 등(1994)이 처음으로 VOF법을 적용한 이래 많은 연구자에 의한 공동연구의 결과로 개발된 CADMAS-SURF(해안개발기술연구 Center, 2001)는 사용자가 직접 입·출력을 제어할 수 있는 효과적인 2차원파동장의 해석프로그램으로 알려져 있다. 국내에서는 김 등(2001, 2002)이 최초로 VOF-SOLA법을 이용한 수치파동수로를 제안하고 잠제주변의 파동장해석을 수행하고 있다.

The economic appraisal of a port remodeling project must be transparent and persuasive to the public over the entire stage of the project. A project evaluator need to be familiar with the guidelines on evaluation, and to do his best to follow the guidelines to evaluate the given project. To make the right decision on investment, the evaluator must take into consideration not only economic efficiency, but also equity issues such as income redistribution and balanced development between regions. Port remodeling projects tend to produce externalities to the environment. However, these externalities are of qualitative nature, and hard to measure in monetary terms, so these are liable to be ignored in the process of project evaluation. Two different approaches - RP(revealed preference) and SP(stated preference) have been tried to assess the value of these non-market goods. Government authorities need to set minimum guidelines which project evaluators must follow in order to make the evaluation more reliable.

This study aims to analyse the actual conditions of Korean fishing boat being seized in Japan's EEZ and to provide the countermeasures against that problem. According to the analysis of that actual conditions, Korean fishermen are trespassing Japan's EEZ in which fishery resources are abundant because of exhaustion of fishery resources and polluted water in Korean coastal sean. In the past, That behavior was not illegal. Now, however, it became illegal with the effectuation of the United National Conventions on the Law of the Sea(1994) and the Korean-Japanese Fisheries Agreement(1999). In order to resolve that problem on a long-term basis, it is necessary to turn over national fishery policy, to provide fishing people with other means of living, and to establish the Korean-Japanese cooperation system of fishery management. Most of all, it is urgent to mitigate and remit a penalty which was executed in Japan, to amplify personal and material resources need to guide and control fishery, and to construct a close cooperation system between the National Maritime Policy Agency and the Ministry of Maritime and Fisheries Affairs.

Technical design codes of slope stability for port structures were studied by comparing local Korean code with international codes; Japanese, EC and China codes. Three international design codes are based on limit state design method. Although Chinese code was based on the modified Fellenius method in slope stability analyses, it is currently changing to the simplified Bishop method. In Eurocode, the Morgenstern & Price method or the Bishop method is recommended. In Japanese code, however, the modified Fellenius method is preferentially recommended, but the simplified Bishop method could be alternatively used in case of thick sandy ground conditions. As for design parameter determination, Eurocode has stipulated comprehensive partial factors and partial material factors, however Japanese code has clarified empirical partial material factors for each port structure. Chinese code, the minimum ranges of the comprehensive partial factors are stipulated, and the use of the strength index by specific tests is concretely clarified with the safety condition. Case study of slope stability analyses showed the safety factors were higher in order of Chinese, Japanese and Eurocode, respectively.

The 1995 Kobe earthquake caused a massive damage to the Port of Kobe. Therefore, it was pointed out that it was impossible to design port structures for Level II (Mw 6.5) earthquakes with quasi-static analysis and Allowable Stress Design methods. In Japan and the United States, where earthquakes are frequent, the most advanced design standards for port facilities are introduced and applied, and the existing seismic design standards have been converted to performance-based design. Since 1999, the Korean Port Seismic Design Act has established a definition of necessary facilities and seismic grades through research on facilities that require seismic design and their seismic grades. It has also established a performance-based seismic design method based on experimental verification. In the performance-based seismic design method of the breakwater proposed in this study, the acceleration time history on the surface of the original ground was subjected to a fast Fourier transform, followed by a filter processing that corrected the frequency characteristics corresponding to the maximum allowable displacement with respect to performance level of the breakwater and the filtered spectrum. The horizontal seismic coefficient for the equivalent static analysis considering the displacement was calculated by inversely transforming (i.e., subjected to an inverse fast Fourier transform) into the acceleration time history and obtaining the maximum acceleration value. In addition, experiments and numerical analysis were performed to verify the performance-based seismic design method of breakwaters suitable for domestic earthquake levels.

This study is enabled our country to compare and analyze Korea's and Japan's marina development related fishing villages in the sea ports, sea port law's systematical research, approved permissions, and operation related ordinance enactments. Henceforth, the results of the research regarding the fisherina development model appropriate for domestic circumstances are as follows. First, the fisherina must be developed in a way to create a new source of income in the fishing villages. The initial steps must be taken in improving the fishing industry and revitalizing the marine leisure sports. Second, there must be a development of a system to reduce its development costs. Third, the existing sea port's unused equipments must be developed in a remodeled form.

전 세계적으로 자율운항선박 및 유관 기술개발이 현재 진행되고 있으며, 기술개발과 상용화를 위해서는 법·제도적 규정 마련이 함께 진행되어야 한다. 국제해사기구(IMO)에서는 2017년부터 자율운항선박의 운용에 관한 규정 검토 작업에 착수하였으며 일본, 중국, 노르웨이 등의 국가에서는 자율운항선박의 운항 및 기술개발을 위해 자율운항선박의 운항에 대한 가이드라인을 제정하고 기존 법률의 정비방안을 발표하는 등 자율운항선박 기술개발과 함께 법·제도 규정마련에 박차를 가하고 있다. 현재 국내에서는 자율운항선박과 관련하여 자율운항선박기술의 개발 및 실증을 하기 위한 법적 근거가 없다.
