해상교총관제는 해상운송에서의 운영적 ${\cdot}$ 환경적 위험을 강소시키기 위한 수단으로써 전 세계 여러 주요 항만과 수역에서 이용되고 있다. 현재 각 국에서는 자국연안에서의 선박통제제도를 적극적으로 실시하고 있으며, 해운의 활성화와 더불어 항만의 안전성 확보를 위하여 각국은 VTS에 관한 국내법을 제정하여 이를 시행하고 있다. 우리나라도 VTS와 관련하여 여러 규정들을 두고 있으나 각 개별입법 내에 산재해 있는 실정이며, VTS를 운영하는 관제요원의 책임과 권한을 명확하게 규정하고 있지 아니하다. 이에 향후 VTS 운영과 관련한 법제의 정비에 관한 논의를 촉진시키는 선행연구로써 현행 VTS 운영과 관련한 법적 문제점을 지적하고 개선방향을 제시한다. 우선 VTS 관제범위에 관한 논의는 국제법적 측면의 법리 정토가 필요하리라 생각되며, VTS 관제요원의 권한과 책임에 있어 적극적 관제에 대한 개념의 정립과 더불어 관제요원의 재인책임과 중과실 경과실에 대한 해상고유의 특성을 반영한 해석이 되어야 할 것으로 생각된다.

This paper presents a mathematical formulation for container slot chartering model through strategic alliance between liner shipping companies. This paper develops a solution procedure to apply the model to real world problems and its applicability is demonstrated by a numerical example. The model presented in this paper has some important features which have never been considered in the previous researches. The model is linear model and pursuits profit maximization. And also it considers slot chartering capacity selection. This paper attempts to perform sensitivity analysis and compares slot chartering model with basic non-collaborating model in which there is no alliance and collaboration. As a result of sensitivity analysis, some interesting findings are obtained; Even though freight rate is more and more decreasing, the profit by slot chartering model is always higher than the basic model but the profit gaps become smaller. But The ratio of the profit gap to the profit of basic model is more increasing.

This paper aims at drawing policy schemes to establish marine clusters so as to enhance Korea's global port competitiveness and applying them to its national management for the advancement of national economy through policy suggestions. The research method is an integrated approach(IA) that comprises SWOT Method with strategic approaches, HFP Model enhanced by KJ Method and descriptive deductions. Strategic schemes established for the SPLC are followed by the group of geographical proximity, integration of ICT, expansion of the interchange of ICT & opportunities of ET, integration of ICT services with marine technologies, supply of integrated services in the SPLC and implementation of organizational policies. In order to make a specific implementation of strategic establishment schemes of the SPLC, we need to select a promotion entity. It is advised to establish the joint organization of the public sector and the private sector, which is considered most desirable. In practice, it is to be followed by promoting support schemes of the organizational policy on the level of national management. In order to reinforce this study, further compensative and proactive researches on the offshore sector with marine clusters are required in terms of the development of the high value added 'blue' ocean.

The increased threat to commercial shipping by Somalia-based pirates has triggered an increased use of PMSC(Private Maritime Security Contractors). The use of PMSC to protect merchant ships against Somali-based piracy threat seems to have been most effective counter-piracy measures. However, there are various legal and practical questions around using PMSC and PCASP(Privately Contracted Armed Security Personnel) on board at sea. This paper aims to study the regulation and its problems of PMSC and PCASP on board to protect merchant ships against Somali-based piracy in the Indian Ocean and Gulf of Aden. In particular, this paper focuses on the legal issues including jurisdictional issues of PCASP on board merchant vessels, use of force by PCASP in self-defense, and authority for using PMSC. Currently, the legal framework relating to use of PMSC and PCASP on board protecting ships from Somali-based piracy is complex, sometimes ambiguous or inconsistent, and currently in a state of flux. Thus, this paper concludes that at this juncture an effort to coordinate this legal framework is necessary, as regards both the interpretation of existing rules related to PCASP on board merchant ships under UNCLOS(United Nations Convention on the Law of the Sea) and the creation of new rules. Also, this paper suggested that there is an urgent need to establish the PMSC-specific laws in Korea.

A thorough inventory of ship emissions, particularly ship's emission of in-port area is necessary to identify significant sources of exhaust gases such as NOx, SOx, PM, and CO₂ and trends in emission levels over time, and reduce their serious effects on the environment and human health. Therefore, the goal of this study is to assess the volume of emissions from ships in Mokpo port, which serves as a gateway to the southwest coast of Korea, using a bottom-up methodology and data from the automatic identification system (AIS) and the Korean Port Management Information System (Port-MIS). In this work, an analysis of ship movement utilizing AIS data and an actual set of data on ship specification were gathered. By examining ship movement using AIS data, We also proposed a new approach for identifying cruising/maneuvering mode. Finally, the results were classified by ship operating mode, by exhaust gas, by ship type, and by berth, which provides a thorough and in-depth analysis of the air pollution caused by ships in Mokpo port.

The purpose of this paper is to estimate the social costs induced by various transport modes such as truck, rail and sea vessel. For this purpose, we introduce the damage function of each transport modes, and estimate social costs for 10 items using Meta Analysis. As a results, this study can find that shipping is the most efficient transport mode because it gives the lowest social costs among them. This study also find that the iso-cost transport distance that gives the equal social costs between the transport modes. Our methodology can be thought somewhat inferior to the Contingent Valuation Methods, however the advantage of this methodology is that we can decomposite the total social costs into item by item and can apply it to other researches.

The coastline of semi-enclosed Hampyung Bay, southwestern coast of Korea, consists largely of erosional sea-cliffs characterized by steep face slope, low in height (less than 3m), and composition of soft reddish soil. Recession rates of the sea-cliffs in the Haeuri coast of Hampyung Bay, which were Quantified by photogrammetry using single aerial photographs taken 1976 and 1990, respectively, were approximately 1${\sim}2m/yr. This value is in good agreement with the field measurement conducted by Chang et al. (1999). Subsequently, the photogrammetry seems to be a very useful method to measure easily long-term coastline change. This severe erosion of sea-cliff in the semi-enclosed bay environment, furthemore, is probably due to combined effects of typhoon or/and storm surges and weak resistance of soil cliff itself.

The flag State is primarily responsible for implementing international maritime conventions(IMO conventions) and national laws and other standards as far as its own vessels are concerned, on the other hand the port State exercise its rights for the safety and marine environment under international law especially UNCLOS within port and territorial sea. In particular, the port State may take appropriate measures including detention of ships identified as sub-standard vessels which are considered as port State's supplementary role aiming for implementing international and national and regulations. But in the course of implementing port state control, international disputes may happen between port state, coastal state and flag state in spite of making all possible efforts to avoid these disputes. This paper aims to consider legal grounds on port state control(PSC) in international conventions and national laws concerned and deals with contradictions between international and national law arising from exercising PSC by port state control officers(PSCOs).

A framework of using and integrating GIS and OR tools for determining the best site selection has been provided. In this research, we demonstrated that both the P-Median heuristic method and MIP method can be successfully applied to the optimum site selection problem of oil tank location selection. Furthermore, the results identified by both approaches are identical. To accomplish this, both GIS road and maritime networks have been constructed and combined to calculated the minimum distance matrix, which is required by both approaches. After the application to the Korean peninsula, the facility locations chosen are Kunsan, Yosu, Busan, and Okgye for each district. As has been shown, the power of GIS and both algorithm have been demonstrated throughout the research and further similar research can also be conducted using the power of GIS and Operations Research tools.
