  • In this study it will be discussed how to solve the problem of discomfort from rolling motion on the fishing boats. Most discomfort is caused by the short cycle of rolling due to the light weight of the boats. The light weight is due to the FRP material which dries a boat. A way to improve the feeling of boarding by using fish hold was researched. The experiment was done on experimental fishing boat made by FRP in Jeju. An existing fish hold was designed and manufactured through the rolling test and that was used for a marine experiment. The rolling condition of the U-tank boat ideally designed was compared to that of an existing fishing boat using the same conditions. The experiments were carried out two times on the stop engine in the outward Sehwa fishing port, which the experimental data had analysed for effects of rolling reduction to compare the U - tank with the of exiting fish hold. The results were confirmed that the U-boat tank in the roll period and GoM were more safe than the existing fish hold and the average amplitude and significant of rolling angles were decreased relatively.

  • The Fishing Communities (so-called Uchongae) in Korea was legally established in 1962. It has been gradually expanded by quantity, and we have total 1,969 communities in 2006. The major establishment purpose of Uchongae was put 2 functions. The first function is to make up the double industry structure in coastal region, and second function is to make economical condition for Uchongae. Nevertheless the Fishing Communities System in Korea was not successfully developed after first beginning. The Income gap have become heavily between fishing area and non - fishing area, including agricultural area. The income gap has been due to rapid industrialization and urbanization in Korea. And the income gap even have become heavily among Uchongaes. In this paper, It have been researched the degree of Income inequality among Uchongaes in Korea during 1986-2006. The income inequality degree was analyzed by Gini coefficient and Mean Log Deviation (MLD) using Lorenz Curve. According to analysis result, the Gini coefficient of Uchongaes in Korea has been about 2-times high from 0.0847 to 0.1770 during 20 years. And the MLD has been 5.4 times from 0.0125 to 0.0679 during same periods. This means to more wide the general Income Inequality among the Uchongaes in Korea. Especially, It means to more wide the gap of high ranking Uchongaes and low ranking Uchongaes that MLD index multiplier has been more high.

  • Since the coastal countries, such as Unite States and other Latin America countries, proclaimed their 200 nautical mile Exclusive Economic Zone, these countries have attention to the need to develop effective coastal management and resource conservation But these countries often perceive themselves as being in competition with each other for profitable for the expansion of the vested EEZ. In such a situation, Exclusive Economic Zone expansion can appear as attractive policy tools in a coastal fishing firms in a noncooperative rivalries with pelagic countries, enable them to expand their fishing share and earn more profits. In reality, the coastal countries strategic Exclusive Economic Zone expansion change the initial condition of the game that both countries' fishing firms play. In this case, the coastal countries' fishing, such as South Korea, Japan and others, act as a followers. As result, the coastal countries' welfare is improved because of pelagic countries profit share shifts to the coastal countries profit share. In this paper, we find that coastal countries strategic EEZ expansion policy may not improve the coastal contries welfare if the shifting profits are dominated by the direct lobbying costs and related resource depletion.

  • We tried to find the optimal growth conditions of sea cucumber and to analyze the economic effectiveness of the sea cucumber seedling release project in Korea. We first examined the optimal growth conditions of sea cucumber in the relating literatures. Then, we analyzed the economic effectiveness of the sea cucumber seedling release project of the Woncheon fishing village union of Gyeongnam Province in 2016-2018 by using the cost benefit analysis method. The net income of the release project of the Woncheon fishing village union was 69,850 Korean won. The benefit to cost ratio of the sea cucumber seedling release project of the Woncheon fishing village union was estimated to be 1.7, indicating that the project was economically feasible. In order to improve the economic feasibility of the sea cucumber release project, as we see in the case of the Woncheon fishing village union, it is necessary to manage the purchase of the sea cucumber seedling, to improve the recapture rate of sea cucumber, and to manage marketing of sea cucumber.

  • A squid gill-net fishing vessel Jayueoroho which was being insured ITC-Hulls and was laid up long period illegally under the condition of unmanned in the Pert of Kamcheon. On 30, March, 1993, the fishing vessel moved out toward the high sea by assistance of two tugboats, 12 miles southeast from Teajongdae, to discharge sewage. At that time the shipowner, the skipper, chief engineer and two labourers were boarding, and a fire was broken out by electric leakage at sea. For all their efforts of fire-fighting operation the fishing vessel foundered with explosion. In this case, she had been breached the warranties of legality, especially Korean maritime acts concerned, and the warranties of seaworthiness(MIA 39(5)) as attributable cause because of unmanned on board by wilful misconduct of the insured. Therefore it is prima facie evidence that the insurer is not liable for any loss attributable to the wilful misconduct and breach of warranties of the insured in MIA 1906.

  • 제주도 어촌의 관광기능 분포는 어촌 외부와의 접근성 보다는 어촌 내부의 관광자원의 영향을 많이 받고 있다. 어촌 관광자원의 영향을 받아 입지하는 관광기능의 어촌공간상 위치는 낚시와 수산물 채취 채포의 바다, 수산물 조리점과 민박의 해안으로 구분되므로, 관광기능의 어촌공간상 위치의 기본 유형은 바다지향 어촌, 해안지향 어촌, 바다 해안 지향 어촌 등으로 구성된다. 이 밖에도 관광기능 위치가 중심어촌 외부인 해수욕장 인접 어촌과 어촌으로의 접근성에서 큰 차이를 보이는 도서 어촌이 관광기능 위치의 유형에 포함될 수 있다. 그리고 이러한 관광기능의 어촌공간상 위치에 따른 관광어촌 유형에 있어 관광기능의 위치가 바다일 때 해안인 경우보다 어업활동과의 관련성과 어촌공간과의 통합도가 높고, 해수욕장 인접 관광어촌과 도서 관광어촌은 각각 시간적 제약과 공간적 제약을 지님으로써 다른 유형과는 차이를 보인다. 따라서 관광기능의 어촌공간상 위치에 따른 관광어촌 유형화는 각 유형간 어촌과의 관련성에서 차이가 드러나므로 관광어촌의 유형화로 볼 수 있다.

  • In order to reduce the risk of death from hypothermia for the fishing vessel's crew at sea, this paper suggests that the criteria of equipment of fishing vessels should be revised for fishing vessels engaged in coastal and inshore fisheries to be equipped with the immersion suit. The criteria of equipment of fishing vessels for immersion suits was amended to reflect the sinking of No.501 Oryongho but it was only reflected in ocean fisheries at Bering sea and Antarctic ocean that immersion suits must be provided with the same number of the total number of crew on board. Therefore, this paper analyses the relationship between maritime accident of fishing vessels and weather condition based on sea water temperature to find out the risk of hypothermia and also compares the international conventions(SFV Protocol 1993, Cape Town Agreement 2012, STCW-F 1995 and SOLAS 1974) and domestic law concerning criteria of equipment of fishing vessels. As a result, fishing vessels engaged in coastal and inshore fisheries are exposed to the risk of hypothermia when they are in distress and the criteria of equipment of fishing vessels should be amended to provide the immersion suits in accordance with the revision trend of international conventions.

  • The purposes of this study were to identify the living environment in rural fishing area and to suggest checking methods for implementation performance. Rural service standard is the key factor of rural development in Korea. In 2012. The first Implementations of performance was announced. The results were presented to the unit by the City and the County. Because of Fishing villages exists as a unit by the haengjeongri. It is difficult to know the status of the fishing villages by the Rural service standard. In order to look for the actual conditions in rural fishing village it was investigated in the 100 Eochongye. The data used in the analysis is 577 questionnaires. Analysis showed that rural fishing areas were superior to general state of rural in the 8 items of rural service standard. Especially housing, transportation and health care sector in rural fishing area wes better than general state of rural. But Public safety and order is relatively poor. This is because Fishing village contains islands. Presenting to improve rural service standard based on the results of research. The items of rural service standard should be measured the actual residents' accessibility than opportunity of the public service, and after setting the rural service standard clearly related to the quality of life of residents in each sector. Accessibility aspects of the customer for the public services should be considered. Checking the performance for the unit by the City and the County should be replaced as a living zone in order to consider the facilities using nearby.

  • The offshore trawl fishery is seeking its survival way to overcome current management conditions in red, resulted from the bilateral agreement with China and Japan. However, this movement magnifies conflicts between fisheries on the contrary and it is thought to be impossible to get over current situations. For all that, this study is aimed at investigating how this current situations have occurred. The management freedom as response to the change in fishing conditions of a certain fishery, in case of Korea, is affected by institutional regulations. The example of this is controls on fishing gears, fishing vessels, and fishing grounds. The most exposure of this control is a segmentation of institutional fisheries. The initial segmentation of the offshore trawl fishery in Korea was occurred in the period of Japan's colonization when the degree of use of fishing grounds was limited geographically. At that time, fisheries were divided by fishing areas, but it did not divide the fishery itself. The large - sized fishing vessels were developed politically to be more competative to Japanese fishing vessels since 1950s. During this time, the trawl fishery was merged into current Eastern trawl fishery and South - Western trawl fishery. It was also inevitable to divide into the pair trawl and single trawl fishery as a result of the physical mergency between Western trawl and Southern trawl fishery. In order to develop the trawl fishery, new licenses were issued on the shrimp trawl fishery, through which it was expected to boost the trawl fishery. As opposed, the shrimp trawl fishery was changed into the mid - sized trawl fishery, targeting on the eastern fishing areas and the large - sized trawl fishery was developed since the late of 1970s with the development of filefish processing industry. The large trawl fishery that led in development of offshore trawl fishery since the late of 1950s was started to divide into a pair trawl and single trawl according to the fishing method and capital power. It finally became an institutionally independent fishery in 1980s, respectively. Looking into these historical process, the segmentation of the trawl fishery is thought as a result of the lack of long - term perspective and as a production of trial and error resulted by unprepared policy. As a result, these segmentation of fisheries roles as critical obstacles in harmonization of fisheries and in overcoming of current situations. Therefore, the review of this institutional segmentation of the offshore trawl fishery should be taken for an optimal redistribution of fishing grounds suits with business and fishing technology. For this, the fishery must be divided into large capitalized fishery and small - mid fishery with consideration of capital, fishing method, and the condition of use of fishing grounds. In addition to this, by limiting outline of fishing ground that the large fishery can harvest, it must allow for the small - mid fishery to catch with its own boundary. Furthermore, by launching buyback programs on the trawl, eastern trawl, pair trawl, it can provide broader fishing grounds where the fishery can harvest with management freedom.

  • 농어촌도로는 농어촌지역의 생활환경개선과 주민의 소득증대를 위한 도로의 정비계획은 물론 농수산물의 원활한 유통을 위한 군도이상의 도로와의 연결을 위한 중요한 지역 기반이다. 이에 대한 기본계획은 농어촌 도로를 기간으로 관할구역안의 도로에 대한 장기개발방향의 지침이 된다. 그러나 기존의 농어촌도로 기본계획은 노선이 위치한 지역상황의 다양한 지표에 대한 종합적이며 합리적인 분석과 평가가 되지 못한 상황에서 진행되어졌다. 그래서 이 연구에서는 농어촌도로의 개발 우선순위 결정을 위해 도로의 노선별 자료를 GIS DB로 구축하였으며, 자료의 종합적 평가를 위해 AHP와 통계분석기법을 활용하여 인자의 가중치를 결정하였으며, 이 과정에서 노선의 개발 우선순위 계산식을 도출 및 적용하여 연구지역 내의 개발 우선순위를 선정하여 제시하였다.
