The purpose of the study is to analyze the status and trend of less favored condition of fishing village in Korean island regions using the census of agriculture, forestry and fisheries. The less favored condition was measured as the difference in accessibility to major services and in fishery sales and resident infrastructure, applying the difference-in-difference method and propensity score matching method respectively. The result shows that access to major services has improved in island area between 2010 and 2015, implying that related policies such as the island comprehensive development project have been successful to some extent. However, some educational facilities, cultural facilities, and health facilities still have low inaccessibility and fishery sales are also significantly lower than in general area. This suggests that it is necessary to maintain related policies like the direct payment of fisheries.

From now on, the direction of fishery products circulation measure should be improved the system to give just the right of free choice of sale route like retail, direct sale, direct dealings and direct shipping only for fishermen to produce them diversifing the function and the role of current fish market in the production to prepare the fishery internationalization, to improve the competitiveness of coastal and off-shore fishery. Practically wholesale market in land and fish market in the production have the different function and role, the organization of wholesale market in land can't substitute the essential function and role which fish market in the production should perform. So far, fisheries cooperatives as a managing subject of fish market in the production have depended on the consignment sales and purchases of fishery products but, from now on, it should be explore the widespread supply way of fishery products by producing value - added fishery products that should bring higher demand from the consumers, producer - consumer direct marketing system through not only consignment sales but also direct sales that common processing and manufacturing system of fishery products under the management of FC has been established. The direction of the idealest structural improvement of fishery production circulation organization is to establish the the position of the fishery retail price leader based on the standard of market in the fisheries production due to existing characteristics of fisheries, accordingly, to harmony the market organization of direct transportation, direct sales and direct dealings form by producer and group of producers with market organization in the fisheries production, and to make the condition to do the appropriate distributive function.

This study was carried out for the hull form development of G/T 340ton class high speed fishery patrol ship by Chosun University at the Circulating Water Channel cooperatively with Korea Maritime Service. Same size of 15knots class fishery patrol ship was selected as a parent form (Model number : CU-015), and modified fore and after body to be suitable for the operation at 20 knots. To minimize the breaking wave in the vicinity of fore body at high speed zone, high bulb nose and slender fore body hull form was chosen as an initial condition. Meanwhile, to ensure the engine room space keeping high resistance-propulsion performance, U-type stern hull form was developed.

It's about time we had to think an alternative to recover out insufficient fishery market caused by IMF locally as well as the fishery agreement on Japan and China. The Ministry of Maritime Affairs ＆ Fisheries have planning the advancing fishery information integrated system for the fishing present condition, marine resource administration and applicability consideration. The fishery information communication system is build up to the raw data ＆ process-network-content. The communication system must be small size, low cost and adapted SSB transceiver, that is using fishery shipping. In this paper We present digital data communication network to exchange information for fishery and safety between fishing ship and coast station in cheeper communication fee using SSB(single Side Band) in HF(High Frequency) band.

The Korean government is in the establishment process of plan for managing fishing effort by setting up the maximum fishing gear usage per fishery type for the recovery of fishery resources, for the settlement of disputes between fishery sectors over fishing gears, and for the stability of fishing business condition. Especially in the setting up of the maximum fishing gear usage, economic standards as well as biological standards are being considered as a significant factor to promote the sustainable and economically viable development of fisheries. This study is, thus, to analyze the optimal economic fishing gear usage ($E_{MEY}$) as the most economically efficient one for the coastal snow crab gillnet fishery, one of the most controversial sectors in establishing the maximum fishing gear usage. The data of logbooks per trip were used for concentrating on the estimation of $E_{MEY}$ per trip because it was considered there were limitations of data available for analyses. As a finding drawn from the analyses, the optimal economic trap usage ($E_{MEY}$) of coastal snow crab gillnet vessels per trip has to be decreased by about 13%. That is, reducing the trip gillnet usage up to the level of $E_{MEY}$ can lead to the reduction of trip fishing costs, thereby resulting in the increased trip profits.

This study identified application range of SPS Code(Special Purpose Ship Code) applied to fishery training ship in Korea, and proposed counterplan for port state control. The latest contents of relevant convention was verified, used APCIS of Tokyo MOU and EQASIS provided by EU to analyze the current condition and deficiencies of port state control of fishery training ship. As the result, the SPS code equal to passenger ship and cargo ship of SOLAS convention should be satisfied with fishery training ship, and must follow ISPS Code. As for the result of record of port state control, it was confirmed that 8 fishery training ships were inspected 76 times and pointed out with 411 deficiencies in Tokyo MOU nation. 75% of deficiencies were related to SOLAS convention, and 71 times of inspections were conducted in Japan. Because it is not free from the fishery training ship, there is a need for active corresponding and preparation by enhancing local cooperative system and sharing the Internet inspection background, and need to develop and implement in-depth internship program to improve port state control counter plan for the trainees.

The aim of this research was to enhance the flavor of visceral extracts from skipjack tuna. Flavor precursors and the optimum condition for the Maillard reaction were determined. The flavor extract was prepared from the tuna viscera using Endo/Exo Protease controlled in 3 factors; temperature, enzyme amounts and incubation time. The optimal condition for producing tuna viscera protein hydrolysate (TVPH) was 60℃, 0.5% enzyme (w/w) and 4-hour incubation time. TVPH were further processed to tuna viscera flavor enhancer (TVFE) with Maillard reaction. The Maillard reactions of TVFE were conducted with or without supplements such as xylose, yeast extract and methionine. The Maillard volatile components were analyzed with gas chromatography-mass spectrometry. Sixteen volatiles such as 2-methylpropanal, methylpyrazine, 2,5-dimethylpyrazine, dimethyl disulfide and 2-acetylthaizone were newly formed via Maillard reaction and the similarity of volatile contents from TVPH and TVFE were virtualized using Pearson's correlation integrated with heat-map and principal component analysis. To virtualize aromagram of TVPH and TVFE, odor activity value and odor impact spectrum (OIS) techniques were applied. According to OIS results, 3-methylbutanal, 2-methylbutanal, 1-octen-3-ol 2,5-dimethylpyrazine, methional and dimethyl trisulfide were the potent odorants contributed to the meaty, creamy, and toasted aroma in TVFE.

The traditional Korean fermented fish products are classified into mainly three groups; Jeot-gal, Aek-jeot, and Sik-hae. Jeot-gal is a salt-fermented fish. Aek-jeot (Eoganjang) is actually a liquid part of Jeot-gal. Sik-hae is a salt-fermented whole or part fisheries with adjuncts. The production of jeot-gal products has been increased constantly. However, there is not enough fishery for raw materials. Recently, consumers have been preferred low-salted foods because they have become aware that high levels of salt cause adult diseases such as hypertension or gastric cancers. The main consumers of jeot-gal are adults above 40~50 years old. Young generation and school nutrition teachers dislike fishery products because of distinct fish smell, small bone, as well as food safety. Therefore, in order to increase the consumption of jeot-gal and extend its industry, jeot-gal should be developed to match the preference of new generation with good safety, health-oriented, and new concept.
