The Korean government has introduced and enforced maritime traffic safety assessment to secure traffic safety since 2010. The maritime traffic safety assessment is needed by law to design a new port or modify an existing one. According to Korea Maritime Safety Act, in the assessment the propriety of marine traffic system consists of the safety of channel transit and berthing/unberthing maneuver, safety of mooring, and safety of marine traffic flow. The safety of channel transit and berthing/unberthing maneuver can be evaluated only by ship-handling simulation. The ship-handling simulation is carried out by sea pilots working with the port concerned. The vessel's proximity measure is an important factor to evaluate traffic safety. The proximity measure is composed of vessel's closest distance to channel boundary and probability of grounding/collision. What is more, the probability of grounding becomes important. According to central limit theorem, a sample has a normal distribution on condition that its size is more than 30. However, more than 30 simulation runs bring about the increase of assessment period and difficulty of employing sea pilots. Therefore this paper is to find out minimum sample size for evaluating vessel's proximity. First sample sets of size of 3, 5, 7, 9 etc. are selected randomly on the basis of normal distribution. And then KS test for goodness of fit and t-test for confidence interval are applied to each sample set. Finally this paper decides the minimum sample size. As a result this paper suggests the minimum sample size of 5, that is, the simulation of more than five times.

Since many RFMOs have been established, various measures to protect small island developing States have been enacted. WCPFC CMM 2017-01 also enacted various measures for that purpose. However, it is notable that CMM 2017-01 has enacted a measure in a manner to reduce benefits of the small island developing States in relation to the vessel charter scheme, although it has made another exception. This study aims to draw implications in establishing Korea's fisheries policy and making an appropriate strategy of the fisheries industries in Korea, through analyses of the charter issue in the WCPFC CMM 2017-01. This paper examines an issue of the vessel charter scheme in the WCPFC CMM 2017-01 comparing with the flag of convenience issue. It concludes that it is recommended to further restrict the application of the vessel charter scheme in the WCPFC CMM 2017-01 and to repeal it ultimately. Finally, this paper draws implications for the Korean government to participate in the WCPFC in a manner to reflect its positions and to harmonize interests of the fishing States and the small island developing States, considering various joint venture business with such States. It further draws implications for the fisheries industries in Korea to actively participate in the WCPFC to maximize their interests.

이 연구의 목적은 해양안전을 위해 해양수산부와 KCG 등에 분산되어 있는 해양안전 집행업무를 효율적으로 운영하는 방안을 살펴보는 것이다. 일반적으로 해양사고는 세월호 사고, 서해훼리호 사고, 태안 허베이 스피리트 오염사고 등에서 알 수 있듯이 인명, 재산, 해양환경 등에 막대한 피해는 물론 재난으로 확대되는 경향이 있어 사고를 예방하는 근본적인 대책이 필요하다. 그런데 우리나라는 대형사고가 발생하면 단편적인 땜질식 처방만 해 왔으며, 세월호 사고 이후에도 관계자 처벌을 위한 후속조치에만 치중하고, 주요 해양선진국에서는 당연시 되고 있는 '해양안전 집행업무 일원화' 같은 근본적인 대책은 거론조차 제대로 되지 않고 있다. 이에 크고 작은 후진성 사고는 끊이지 않고 있으며, 선박의 대형화·고속화·노후화, 선원의 자질저하, 선박통항량의 증가, 해양레저의 발달, 해양안전업무의 이원화로 인한 비효율성 등으로 대형 해양사고, 후진성 사고의 개연성은 더욱 높아지고 있는 것이다. 따라서 해양안전 관련 선행연구 검토, 주요 해양선진국의 사례 및 VTS의 일원화 사례 등을 토대로 해양안전과 직결되는 내항선 안전관리·PSC·항로표지관리 등의 해양안전 집행업무의 효율적인 운영방안을 제시한다.

Almost of all the impediments to enchancing ship safety and preventing vessel-source marine pollution arise from the interaction between direct and indirect factors. The direct factors come from human errores and failure in complince with the international convention standards for the operation of vessels. The indirect factors derive from the will and attitudes of the countries taking little responsibilities with appropriate seriousness for policing their fleets. By focusing in these aspects, this paper intends to propose a new international regime to improve the implementation capability of national maritime administration of each member government of IMO(International Maritime Organization).

Due to global climate change, Korea is experiencing flooding and drought severely. It is hard to manage water resources because intensive precipitation during short periods and drought are commonly occurred in Korea, recently. Severe drought occurred in 2015 and 2017 in the islands, and coastal and inland areas in Korea, and the citizens experienced decreased water supply and emergency water service by using bottled water. Therefore, the Korean government provided additional governmental funds such as the grant of drought disaster. In this study, we tried to calculate the cost of water for drought response based on the cost of tap water for the regional local governments in Korea and the grant of drought disaster by the Ministry of the Interior and Safety in Korea, etc. The estimated costs of water for drought responses in coastal and inland areas which have a chance to apply alternative water sources such as brackish or seawater desalination and water reuse in Korea were higher than in other areas in Korea. Additionally, as the novel approach of drought response, the 300 ㎥/day-scale desalination vessel was suggested to provide desalinated water for the islands in Korea. The estimated expenses of water supply for the target island areas (Sinan-gun and Jindo-gun) by the desalination vessel was lower than those by emergency water service by using bottled water.

우리나라 연안 해역은 빈번한 선박조우로 인한 해양사고 발생 잠재 위험이 높은 해역이며 현재 각 항만의 VTS 관제실에서 VHF통달거리를 넘어서 통항하는 선박에 대하여는 정보 파악 자체가 불가능하고, VTS 관제범위 바깥해역에서는 효율적인 교통관리가 어려워 관련사고 예방이 어려운 실정이다. 최근 우리나라는 항만의 확장 및 신항만 개발에 따른 해상교통안전성 평가는 있지만 실시간으로 변화하는 해상교통환경 변화에 따른 위험도 정보를 제공할 수 있는 시스템은 없는 실정이다. 따라서 대상해역에서의 해상교통환경과 관련된 일반적인 정보 및 위험도 정보를 제공하고, 해상교통환경 평가를 통한 해역 위험도 여부를 평가할 수 있는 평가지표 개발이 필요하다. 본 연구에서는 선박운항자의 위험의식을 바탕으로 선박의 전장별, 선박의 조우 형태 중 횡단(Crossing situation) 상황에 따른 마주치는 각도($045^{\circ}$, $090^{\circ}$, $135^{\circ}$), 추월(Overtaking) 및 정면으로 마주치는 경우(Head-on situation)와 좌현, 우현에서 선박을 조우하였을 경우와 항계 내 및 항계 밖에서의 경우, 타선과의 속력 중 비슷하거나 또는 느리거나 빠를 경우, 타선과의 속력차에 따른 경우, 타선과의 거리에 따른 선박운항자의 주관적 위험도를 조사 분석하여 해상교통안전성 평가모델 개발을 위한 기초 식을 제안하였다. 제안한 기초 식은 국내 해상교통환경 평가에 적합한 것임을 확인하였다.

The purpose of this study is to examine the determinants of management performance in the remaining offshore fishing industry after the resource management-oriented fisheries structure improvement policy by the fisheries vessel buy-back program and Total Allowable Catch (TAC). The results of the analysis of the determinants of management performance of offshore fishing can be summarized as follows. First, based on the management performance determinant model of offshore fishing, it is confirmed that the government's resource-managed fishing structure improvement policy, such as the fishing boat reduction project and the TAC policy, is improving the management performance of the resource-managed remaining fishing boat. Second, looking at the specific management performance determinants based on the management performance model of offshore fishing, the leverage ratio (TLTA), which is the total debt ratio, shows a statistically significant positive (+) relationship with management performance, which increases management performance directly proportional to the leverage ratio. The increase in the leverage ratio (total debt ratio) was expected to lead to a high interest cost burden, resulting in a reverse (-) financial leverage effect; however, rather a positive (+) financial leverage effect occurred with a high profit covering interest costs. The total catch (TCATCH) has a positive (+) relationship with management performance at a statistical significance level of less than 1%, indicating that an increase in catch is improving or increasing the management performance of fishing companies. The selling price (UPRICE) shows a positive (+) relationship with management performance at a very high statistical significance level of less than 1%, and it can be seen that high fishing prices are a major factor in improving or increasing the management performance of offshore fishing. On the other hand, fishing vessel tonnage (TON), fishing vessel horsepower (RHP), and operating days (WDAYS), which indicate have a statistically significant negative (-) relationship with management performance, which deviates from the existing fisheries common sense that the size of fishing vessel tonnage and fishing vessel horsepower and the increase in the number of operating days is proportional to management performance. As a result of the increase in fishing vessel tonnage, horsepower, and the number of operating days, it was confirmed that the higher the fishing cost, such as oil costs, is worsening the management performance of fishing companies. Participation in TAC has a statistically significant positive (+) value with management performance, indicating that the remaining offshore fishing companies participating in TAC are improving or increasing management performance compared to offshore fishing companies that do not. Third, there are conflicting results depending on the industry as a result of estimating the management performance determinants of offshore fishing by TAC participation, and TAC participation had a negative impact on management performance in anchovy boat seine and southern west sea bottom trawl in fishing industry while TAC participation had a positive impact on management performance in large stow nets on anchor in fishing industry.

The maritime industry is important for Korean international trade, as more than 99 percent of its imports and exports are moved by maritime transportation. However, if maritime transportation is stopped in the event of an emergency, such as war or natural disaster, there is a danger that imports and exports may cease abruptly. Coping with this risk is why the Ministry of Oceans and Fisheries, manages the 'National Necessary Shipping System.' This system requires that the government estimates the size of ships necessary in the case of an emergency, and the ships designated as National Necessary Vessels should transport goods in the case of actual emergencies. This study seeks to estimate the appropriate size of ships required in an emergency using the latest data and applying a quantitative methodology. This study provides useful reference materials for policy authorities. In particular, it is meaningful that this study estimates the required number of ships of each vessel type, reflecting the recent trend of large-scale ships and expanding global trade.

Nowadays LNG has been beginning to take the place of petroleum as fuel all over the world and VLCC of LNG will take the same sea routes that had been used by VLCC tankers of petroleum in the last part of the 20th century. The transportation of LNG by a VLCC include more dangerous nature of sea peril than that of petroleum. We already know the dimensions of a disaster a LNG tanker could bring about in the case of the LNG tanker, Yuyo-Maru No. 10 in the Tokyo Bay of Japan in 1974. From the point of safety when we construct a LNG base or LNG pier in the base, the appropriate government authority and constructing company had better take sea pilots or some ships handling experts to participate in a prior consultation of the design of the project. A G/T 100,000 ton LNG base and pier were completed in November of 1996 in Inchon harbour in Korea and VLCC of LNG of G/T 100,000 ton class have been entering into the base ever since. This study was started and completed In comply with the requisition of the Sea Pilot Association of Inchon harbour in advance of the opening of the LNG base. As the entrance and exit channels leading to Inchon harbour were constructed in the years of 1930s, it was one of the most pressing works for Inchon sea pilots in 1996 to certify the method of safe passing maneuvering of a G/T 100,000 ton of LNG tanker through the Pudo narrow channel prior to commencing actual piloting of the VLCC of LNG. The authors made some mathematical models computing maneuvering of a vessel changing her course with her control surface through a narrow channel and computed maneuvering of a G/T 100,000 ton of LNG tanker and also made maneuvering simulations of the vessel by a desk-top simulator. The results of computations and simulations are well coincided with each other in qualitative aspects to assure safe passing of the VLCC of LNG.
