Agro-fishing villages of agriculture and fishery are suffering deepening gap with urban areas due to depreciation from their products market opening pressure. They are facing problems of decreasing and aging population, poor settlement environment, etc. and losing their vitality for their low productivity and lack of young labor force. These issues of agro-fishing villages of agriculture and fishery are divided in so various items and classes that it is plausible to approach in a way to connect each issue in a small frame of each by selecting sub topics according to each item and each class rather than to solve the issues in a large frame. Chungchungnam-do is approaching the issues through 3 agro innovations(agro fishery, agro fishing villages, agro fishing people) in local government level and Durae enterprises are solving local problems through the self supporting residents' community business by utilizing local resources. This study is to draw clues and solutions to vitalize agro fishery villages through community businesses by detailed reviews and research on cases of Durae enterprises' characteristics and their vitalizations and provide a new alternative plan to agro fishery villages losing their vitality and demolishing their communities.

A product consists of some parts. The integrity of a product might not be explained from individual parts. The fishery processed goods can be used as a model. The characteristics which derives from a product as a whole is more important than right or wrong of individual parts. All commodities to appeal for consumers have much in common. I explain the process of producing a new tasteful commodity by observing the fishery processing goods business. This is a part of data acquired from a research at a fishery port in Japan. (1) A project manager should be a person in charge of marketing, which makes success easier. (2) A product and process design should be done concurrently. (3) As for a synthetic architectural commodity, a strong leader is a must. (4) To understand material and sensibility information, we can use the above-mentioned.

Changing concepts in fishery science increasingly are recognizing depletion of traditional stocks, utilization of alternate(non-traditional) species, demand for high quality products, and a total resource utilization approach. Innovative practices are occurring in fisheries processing wherein solid and liquid discharges are no longer treated as 'waste,' but rather as valuable feedstocks for recovery of a variety of value-added ('value enhanced') by-products. Among these are protein hydrolysates, soluble proteins and amino acids, proteolytic enzymes, flavor and flavor extracts, pigments, and biopolymers such as chitosan. Properties and applications of this deacetylated derivative of chitin are noted. Crustacean processing by-products are discussed in terms of their serving as materials for generation of natural flavors and flavor extracts, and products such as fish sauces using contemporary enzymatic techniques. Various food and feed applications of fisheries processing by-products are illustrated with increased usage seen in formulated diets for an expanding aquaculture market. Examples are given of aquaculture becoming increasingly significant in global fisheries resource projections. Critical issues in the international seafood industry Include those of seafood quality, processing quality assurance (HACCP), and recognition of the nutritional and health-related properties of fisheries products. A variety of current seafood processing research is discussed, including that of alternate fish species for surimi manufacture and formulation of value-added seafood products from crawfish and blue crab processing operations. Increasing emphasis is being placed on international aspects of global fisheries and the role of aquaculture in such considerations. Coupled with the need for the aquatic food industry to develop innovative seafood products for the 21st century is that of total resource utilization. Contemporary approaches in seafood processing recognize the need to discard the traditional concept of processing 'waste' and adapt a more realistic, and economically sound, approach of usable by-products for food and feed application. For example, in a period of declining natural fishery resources it is no longer feasible to discard fish frames following fillet removal when a significant amount of residual valuable flesh is present that can be readily recovered and properly utilized in a variety of mince-based formulated seafood products.

This paper deals with the development of the high frequency thawing machine. The fishery products caught over the world are kept frozen to maintain freshness. These fishery products require thawing before they are sold to customers as food. However, the thawing process can cause freshness reduction, drip coming out, quality deterioration, discharging polluted water, as well as a lot of space and time. The high frequency thawing machine developed to solve this problem has a narrow space, a short thawing time and a small drip. The developed high frequency thawing machine can be used in many fields such as fish processing plant, livestock processing plant. This paper describes the design of the high frequency thawing machine by developing the high frequency generator, development of the controller, and the design of mechanism, and shows the superiority of the high frequency thawing machine by the performance evaluation.

This paper tries to apply the asymmetrical price transmission(APT) behavior observed in the agricultural industry to supply chains of the domestic fishery industry by a statistical manner. The fore mentioned asymmetrical price transmission refers to when price movements in the later stage of the supply chain do not move in a normal or symmetrical manner corresponding to price movements in the earlier stage of the supply chain. Therefore, when the earlier stage price increase and the later stage price increases to a larger degree, it is called positive(+) asymmetry and the opposite behavior is called negative(-) asymmetry. The study examines the data from domestic producers of three fresh fish types, hairtail, mackerel, and cuttlefish, and tries to examine the price asymmetry between the producer or farm, wholesaler, and retail prices via an APT test utilizing unit root, cointegration, and error correction model. The study found, hairtail wholesale and retail pricing bas a negative asymmetric relationship while mackerel has a negative asymmetric pricing relationship at the producer and retail levels of the supply chain. In the case of cuttlefish, all levels of the supply chain showed negative asymmetrical behavior in the supply chain price transmission, meaning the earlier stage price changes are more rapidly and greatly inputted in the later stage of the supply chain pricing. We believe that the reason why the analysis results show negative price asymmetry is due to the uniqueness of fishery products having an important variable such as freshness. If price increases are greater and quicker than price decreases, then consumer demand, which is sensitive to price increases will decrease and subsequently result in the increase of inventory levels, reducing profits for retailers. Also, frozen hairtail, mackerel, and cuttlefish will act as substitute goods to fresh fishery products. Therefore, fresh fishery products have a high demand of price elasticity. When prices increase, demand quickly decreases. Therefore the profit of wholesalers and retailers to decrease, I think this is the main reason of APT in the supply chain of Korea' s fisheries industry.

By analysing the benzo(a)pyrene concentration using HPLC-FLD and LC-MS/MS, pollution levels of herbal medicines without permitted benzo(a)pyrene specification were investigated. Average benzo(a)pyrene concentrations were 38.30, 37.46 and 21.22 ㎍/kg for Amomi Tsao-ko Fructus, Mume Fructus and Coptidis Rhizoma, respectively, which are 4 to 7 times higher than maximum permitted benzo(a)pyrene concentration of Rehmanniae Radix Preparata and Rehmanniae Radix, i.e. 5.0 ㎍/kg. Proportion of detected samples exceeding 5.0 ㎍/kg benzo(a)pyrene concentration was 22% for Cimicifugae Rhizoma and Scrophulariae Radix, 44% for Forsythiae Fructus, 67% for Mume Fructus, 100% for Amomi Tsao-ko Fructus and Coptidis Rhizoma, and collectively 29% (36 out of 125 samples) in average. In terms of risk characterization results, human exposure of benzo(a)pyrene were 7.96, 3.49 and 1.61 ng/kg b.w./day and the margin of exposure(MOE) were 1.25 × 10⁴, 2.86 × 10⁴ and 6.20 × 10⁴ for Mume Fructus, Amomi Tsao-ko Fructus and Coptidis Rhizoma, respectively. MOE banding of those herbal medicines was categorized to 'low concern'. However, considering that human exposure of benzo(a)pyrene for food is legislated to 1.4~2.5 ng/kg b.w./day, it was urgent to set up the guideline of benzo(a)pyrene in herbal medicines.

Fermented foods available in Korea may be classified into four groups, namely, fermented soybean products, fermented cereal products, fermented vegetable products, and fermented fishery products based on raw materials used. The representative fermented foods based on soybean are Kanjang(soysauce), Doenjang(fermented soybean pastes), and Kochujang(red pepper added-fermented soybean paste). Such fermented products are made using Meju(functioning as a starter and prepared by fermentation of steamed soybean mash) as an essential ingredient, and used widely as a soup base and/or in seasoning side-dishes for everyday meals year around. Excepting Sikhae, all fermented products based on rice and other cereal grains are of alcoholic nature. Takju (Makgeolli) used to be made using rice as the major raw material, however, mainly due to the shortage of rice in recent years, other cereals, such as, barely, corn, and wheat flours are also used to replace rice today. Owing to such changes in the raw materials. the popularity of Takju has been somewhat reduced, yet it is still widely consumed in rural areas. Although Chungju is a popular rice wine with superior qualify over Takju, the amount consumed is considerably limited. The highest qualify rice wine, Bupju, in particular, is made by a low temperature fermentation using glutinous rice. Kimchi is an unique fermented vegetable product of long tradition in Korea. Although it was for consumption mainly in winter season serving as a source of vitamins, today it is widely used throughout the year. Except Kkakdugi and Dongchimi, all of the fermented vegetable products contain salted Korean cabbage as an essential item, while they abound in varieties depending on material composition and methods of processing, and also on seasons and localities Next to Kimchi in this category is Kkakdugi made of raddish in popularity and quantity consumed. The four groups of fermented food products described above are reviewed in some detail and evaluated in terms of their nutritional significances, processes and microorganisms involved. and their commercial potentials. Jeotkal (or Jeot) is a name given to all fermented products of fishery origin. A number of Jeot can be prepared by adding salt and allowing fermentation to the raw materials such as shrimp, anchovy octopus, clam, oyster, etc.

This study aims to examine the change of fish market(魚物市場) and inland brokers(客主, kaegju) on Gunsan(群山), (1899-1919). The increasement of productive capacity in the agriculture and the development of exchange economy in the late period of Chosun Dynasty activated the distribution of fishery products. As a result, the inland brokers who participated in the production and distribution of fishes grew largely. They made the basement of fishery modernization by providing the funds for the fisheries and making the national distribution network. But Japanese fishermen began to hold the domestic market as the Japan government supported legislatively and economically after the opening ports of Korea. On the contrary, the distribution of fishery products had the characteristics different from the production of some. The case of Gunsan which opened in 1899 showed these characteristics as Gunsan is a short distance from Kangkyung(江景), one of three biggest markets and was a base of fishery, That is to say, though the fishery merchants from Japan set up 'a fish market'(魚市場), they didn't hold the sales network on Gunsan, Because the inland brokers on Gunsan had a sales network and began the socio-economic movement. It goes without saying that the instability of price, the difficulties of charge and the racial taste difference in fish made the fish sales from Japan confronted with the difficulties. After Japanese Imperialism enforced the Company Law, the Market Regulation, the Chamber of Commerce Law before or after 1910, Korean inland brokers were disprited and Japanese 'fish market' began to grow largely. These phenomena appeared on Gunsan, too. Especially, the opening of a railway was the main factor which strengthened Japanese 'fish market'. After 1915, Japanese 'fish market' on Gunsan defeated the distribution network of inland brokers.

본 연구는 식약공용 오미자를 메탄올 추출해 schizandrin, gomisin A, gomisin N 함량을 확인한 후 schizandrin, gomisin A, gomisin N 함량이 높게 나온 시료 중 하나를 선정해 오미자를 차로 음용 시 물 추출방법에 따른 생리활성 물질의 함량을 확인하였다. 추출방법은 열수 추출과 상온 침출로 추출상태, 추출온도, 추출시간을 달리하여 schizandrin, gomisin A, gomisin N 함량을 비교하여 적절한 음용법을 제시하고자 하였다. 오미자를 원산지별 메탄올 추출물 시 schizandrin, gomisin A, gomisin N 총 합 평균 함량은 10.57 mg/g이었다. 국산 오미자 11.42 mg/g, 수입산 오미자 10.12 mg/g으로 국산 오미자의 메탄올 추출물의 schizandrin, gomisin A, gomisin N 총 합 함량이 더 높았다(p < 0.05). 메탄올 추출에서 높게 나온 오미자를 이용해 물 추출 방법에 따라 추출방법, 추출형태, 추출온도, 추출시간을 달리해 생리활성 schizandrin, gomisin A, gomisin N의 함량을 확인한 결과 오미자 물 추출방법에서 생리활성 물질의 함량에 가장 큰 영향을 준 조건은 추출형태였다. 원형보다 분말형태로 오미자를 물 추출 시 생리활성 물질의 함량이 높게 나왔다(p < 0.05). schizandrin, gomisin A, gomisin N의 총 합 함량이 높게 나온 추출방법은 오미자를 분말형태로 $26^{\circ}C$에서 24시간 침출하거나 $100^{\circ}C$에서 5분 이상 열수 추출했을 때 유의적 차이가 없이 높게 나왔으나(p > 0.05) 오미자를 고온 열수 추출 시 떫은맛과 신맛이 강해지므로 따라서 오미자의 물 추출의 경우 분말상태로 24시간 이상 침출하는 것이 오미자의 생리활성 물질인 schizandrin, gomisin A, gomisin N을 좀 더 효율적으로 추출하고 기호적인 면도 고려할 수 있는 음용법 이었다. 차를 마시는 기능성을 고려하여 향후 오미자 뿐 아니라 가정에서 차로 많이 사용하고 있는 다양한 약용식물의 생리활성 물질에 특성에 따른 물 추출물에 대한 효율적인 추출법등의 연구가 이루어져 할 것이다.
