  • This study attempted to investigate the demands of fishing village people and the actual status of their living, to diagnose the problems in fishing villages and to present some basic data for fishing village development. The major findings of this study were as follows ; 1) The problems in fishing village of Korea included fishing village, household debt, big fluctuation of fish prices, children's education, cultural and welfare facilities need to investment for equipment, marriage and health. 2) The respondents said that fishing village household debt was mainly caused by lack of income from fishery(37%), educational expenses(28.5%), excessive fishery expenses(20%), excessive fishery equipment(15%), and government policy(12%). 3) The outlook of fishery development is considered bright by the respondents. They said that fishery would be a prospective industry if the appropriate conditions are given. Considerable research efforts for government policies will be needed to develop the fishery industry.

  • PURPOSES : To evaluate the feasibility of cut waste fishing net as a reinforced fiber for concrete. METHODS : Strength characteristics of fiber reinforced concrete using waste fishing net were investigated. The cut waste fishing nets with 4~5cm length were putted into the soil-cement and cement concrete for pavement slab. RESULTS : Compression and tensile strength of fiber reinforced concrete using waste fishing net were increased. CONCLUSIONS : It was concluded that cut waste fishing net can be used as a reinforced fiber for cement concrete. However, sometimes using cut waste fishing net leads to decrease the strength; therefore, further researches are needed for real project.

  • Schooling behavier to a fishing gear and estimation of the volume of fish school in set net have ~ been studied by making use of such techniques as visual observations, underwater cameras, under- water televison. However, all of these observation techniques are subject to restrictions caused by illumination, underwater visibility, underwater transparent and sea conditions. For the above mentioned reasoa, one of the most effective method by this time become generally known a method using fish finder. In this paper, in order to control the fishing ground of set net effectively and to develope the telemetric fish finder, the experiments for the target strength, underwater shape of fishing gear, schooling behavier and volume of fish school with fish finder were performed at Galgott fishing ground of set net located Keouje Island, 15th-24th July and 18th-20th October in 1985. The results of these experiment showed that a method using fish finder in fishing grOlllld of set net is available for estimating distribution and school size, fish behavier in relation to a fishing gear and underwater shape of fishing gears.

  • In order to offer data about fisheries resources management and prediction of catch on large purse seine fisheries, the fluctuation of the fisheries condition and distributions of fishing ground for mackerel were analysed with monthly catch data for 1990.2009. The overall catch has decreased to about 70% since 1997, with approximately 70% of the mackerel (Scomber japonicus) catch and monthly fluctuations showing a similar pattern. Monthly distribution of fishing ground is like distribution of mackerel in large purse seine fishery. The main fishing grounds are near Jeju Island and the Yellow sea with the main fishing season existing between October to December. The catches fluctuations and distribution of fishing ground were related to the effect of regime shifts. Therefore, in order to prediction of catch on large purse seine fisheries should be studied these relationships.

  • The purpose of this study is to estimate the economic value of boat fishing experience marine tourism activity in Jeju Island's Chagwido. The economic value is estimated as consumer surplus using count data models including the truncated Poisson model and the truncated negative binominal distribution model. This study collects the effective 504 questionnaires from boat fishing experience tourists in Jeju Island's Chagwido. The truncated negative binominal distribution model was statistically more suitable and valid than other models. The truncated negative binominal distribution model was applied to estimate consumer surplus as economic value from boat fishing experience tourism activity in Jeju Island's Chagwido. A consumer surplus value per trip was estimated as about 209,900 won. The annual economic value from boat fishing experience tourism activity was estimated as 273,700 won in Jeju Island's Chagwido. Consequently, boat fishing experience marine tourism activity has a very large economic value in Jeju Island.

  • The computer programs of effective horsepower estimation of small fishing boat were developed, which was based on the statistical analysis of model test results. From the EHP estimation by these program and experimental model tests of practical fishing boats, the estimation accuracy was verified with maximum deviation of about 10 percent. Also, the EHP estimation accuracy was practically applied to initial design of four small fishing boats, and after the tank tests, the EHP reduction of the order of 15 to 25 percent was confirmed, as compared with existing ships. Moreover, a computer aided design procedure of fishing boat's hull form has been proposed in this study. The practical use of this procedure of fishing boat's hull form has been proposed in this study. The practical use of this procedure was demonstrated with the hull form design results of several fishing boats.

  • The fishermen around fishing villages have organized the Eo Chon Gae, a co-operative organization based on the Fisheries Co-operative Law. The Eo chon Gae plays a vital role in the fishing village community, and the common economic, administrative and social profits are expected by members. The members of the Eo Chon Gae must work together in a common coastal fishing ground, this fishing ground is jointly owned by the community, and the members have to conduct the Eo chon Gae jointly for their common profit. This system, as mentioned above, is called the Eo Chon Gae, which is generally called a fishing village community, or a fishing administrative community. The purpose of these theses is to consider what kind of character and principles the Eo Chon Gae has. The contents of these theses are divided into six parts: 1. The various concepts of the fishing administrative community 2. The progress of the Eo Chon Gae. 3. The organization of the Eo chon Gae. 4. The purpose of the Eo chon Gae. 5. The work of the Eo Chon Gae. 6. Types of the Eo Chon Gae.

  • On this paper, the methods of optimization research of the fishing navigation using the graph theory are substantiated on the basis of the proposed probable model of the fishing vessel navigator's activity. The graph theory is concered about the transitionform the top graph to the rib one. And the definition of the additional system elements (quasi elements) necessary to provide the effectiveness during the fishing navigation are also substantiated herein. This approach helps to optimize the structure of any fishing vessel monitoring system.

  • Ghost fishing이란 유실되거나 버려진 어구가 바다 속에 방치된 채로 어획을 계속하고 있는 상태를 의미하며, 이것이 주목받게 된 것은 1960년 FAO가 Ghost fishing의 심각성을 지적한 이후이다. 1950년대까지는 어구에 쓰이는 그물이 천연 재료였기 때문에 유실 어구는 일정 기간 후에 바다 속에서 부패되어, 어구로서의 기능을 상실하게 되므로서 Ghost fishing이 크게 문제시되지 않았다. (중략)

  • 외국인 선원은 1990년대 선원 수급이 어려웠던 어선에 산업연수생으로 승선하기 시작하여 2013년말 현재 상선 및 어선에 총 21,327명이 승선하고 있다. 특히 원양어선 및 연근해어선의 경우에는 최근 5년간 어선 척수가 감소하고 있음에도 불구하고 외국인 선원의 수는 거의 2배 증가하였다. 최근 어선 해양사고를 살펴보면, 어선에 다국적의 선원이 승선한 후 선원 상호간의 의사소통이 어려워진 것이 주요 문제가 되었다. 그리고 외국인 선원이 이해할 수 있는 안전수칙 등이 제공되지 아니하고 교육 훈련이 제대로 이루어지지 않고 있다. 그 결과 어선은 조업 중 해양사고의 발생 위험이 높아졌고, 비상상황에서 선장의 통제 하에 적절한 비상대응이 이루어지지 않았다. 또한 한국인 선원의 외국인 선원에 대한 폭언 및 구타로 인한 몇 건의 노동문제가 발생했다. 따라서 본 논문은 먼저 외국인 선원이 승선한 어선에서 발생한 해양사고 사례와 어선원의 고용 및 교육문제에 대해 살펴보고, 해양사고 예방을 위하여 외국인 선원에 대한 안전수칙교육과 정기적인 비상대비 교육 훈련의 필요성을 제시하고자 한다.
