In this study, the Inter-Korea Fisheries Cooperation Project was divided into four categories: North Korea's Fisheries Infrastructure Development Project, Fisheries Cooperation Project, Human Exchange Project, and North Korea Fisheries Investment Project. First, North Korea's fisheries infrastructure development projects include North Korea's fisheries resource research project, it's fisheries resource development project, and joint enforcement on illegal operation of Chinese ships. Second, fisheries cooperation projects include the operation of the North-South common fish area in the West Sea, the fishing project in North Korea's East sea, and the import of North Korean seafood. Third, human exchange projects include training of aquaculture technicians in North Korea, technology transfer and training of fishing vessels, and boarding of North Korea's fisherman in Korean fishing vessels. Fourth, North Korea's fisheries investment projects include aquaculture facilities and aquaculture feed support, aquatic product processing facilities and technology transfer, and fishery equipment support. However, as international sanctions are maintained in the international community to North Korea, Inter-Korea Fisheries cooperation, however, should be promoted according to the level of easing of international sanctions as international sanctions are maintained in the international community to North Korea. First, North Korea's fisheries resource research project, North Korea's fisheries resource creation project, joint enforcement on illegal operation of Chinese ships, and operation of the common fish area in the West Sea can be promoted if international sanctions are maintained at present, promote North Korea's fisheries resource research project. Second, boarding of North Korean's fisherman in Korean fishing vessels, conducting the fishing project in North Korea's East sea, and importing North Korean seafood can be aided if commercial transactions are possible with North Korea. Third, South Korea will support aquaculture facilities and aquatic feed, fisheries processing facilities and technology transfer, fishery equipment support, training of fisheries and aquaculture technicians, fishery fishing technology transfer, and training of fisherman when a comprehensive economic cooperation project is possible with North Korea.

The purpose of this study is to test the effects of electrolyzed water treatment on dried-laver Pyropia sp. processing facilities to control microbial contamination. Following the progression of the process to the next step, as well as during the lapse between process operating hours, the contamination level of total viable cell counts (TVC) and total coliform (TC) of laver increased. The TVC increased during the aging step, and after the molding-drying steps were completed, it increased by approximately 2.0 log CFU (colony forming unit)/g. Freshwater used for processing in April had a TVC of 4.31 log CFU/mL, which was more polluted than 2.61 log CFU/mL of seawater. Electrolyzed water was used to treat the sponge used in the laver-molding process, which resulted in a 2 log CFU/mL decrease.The TVC of dried-laver decreased by 1 to 2 log CFU/g when electrolyzed water was applied to the process. In conclusion, application of electrolyzed water in dried-laver processing was shown to be effective in reducing the microbiological contamination of the final product.

There is a limitation to estimate vitamin $B_{12}$ intake due to a lack of data on vitamin $B_{12}$ content in many Korean foods. In this study, vitamin $B_{12}$ content was determined in some seaweeds, fish, and shellfish and their product that are consumed in Korea using a modified microbioassay with Lactobacillus delbruecki ATCC 7830. Dried laver and dried seasoned and toasted laver contained very high levels of vitamin $B_{12}$ (66.8 and $55.2-71.3\;{\mu}g$/100 g, respectively. Sea lettuce and seaweed fulvescene also contained high vitamin $B_{12}$ content of 5.47-9.41 and $6.46-7.20\;{\mu}g$/100 g, respectively, whereas sea mustard and sea tangle contained low levels of vitamin $B_{12}$; vitamin $B_{12}$ was not detected in seaweed fusifome. Pacific saury, trout, sea-bass, or squid contained 12.01, 2.00, 0.49 and $2.33\;{\mu}g$ vitamin $B_{12}$/100 g, respectively. Ochellatus octopus, and naked sand lance contained 0.72-1.43 and $3.68\;{\mu}g$ vitamin $B_{12}$/100 g, respectively. Dried Alaska pollack con-tained $0.19-2.64\;{\mu}g$ vitamin $B_{12}$/100 g. Shellfish such as little neck clam and small ark shellfish contained high levels of vitamin $B_{12}$ of $30.5-40.5\;{\mu}g$/100 g, and mussel and abalone contained 17.71 and $7.82\;{\mu}g$/100 g, respectively. Of unique Korean traditional fermented seafood products, salt-fermented products of squid ($2.91\;{\mu}g$/100 g), clams ($34.31\;{\mu}g$/100 g), Ala-ska pollack roe ($9.98-12.02\;{\mu}g$/100 g), hairtail guts ($4.58\;{\mu}g$/100 g) or small shrimp ($0.58-1.55\;{\mu}g$/100 g), and fish sauce from anchovies ($1.52-1.78\;{\mu}g$/100 mL), sand eel ($0.22-0.24\;{\mu}g$/100 mL) or small shrimp ($0.19-0.78\;{\mu}g$/100 mL) were analyzed. A few commercial brands of flying fish roe ($0.73-1.73\;{\mu}g$/100 g), canned tuna ($0.40\;{\mu}g$/100 g), and fried fish paste ($0.25-0.69\;{\mu}g$/100 g) were also analyzed. In conclusion, vitamin $B_{12}$ content in these foods, chosen considering the Korean food culture, should contribute to improve the present vitamin $B_{12}$ food database. It may be helpful to estimate vitamin $B_{12}$ intake more correctly than before, and provide additional information for dietary education related to vitamin $B_{12}$ and meal management.

Import refusals can be considered a new method of non-tariff barriers. This study aims to analyze reputation spillover effects on fish and fishery products imported from ASEAN countries to the U.S. FDA. The supply of aquatic products is not stable due to various factors such as reduction of fish stocks and climate change. Fish is a basic food ingested directly, but there are many ways to control the safety of aquatic products. ASEAN countries account for about 20% of U.S.imports in fish and fishery products. For Southeast Asian countries, fish and fishery products comprise a high proportion of exports revenue. Despite the large share of exports to the U.S., Southeast Asia countries have been receiving many import refusals from the United States. In this study, a theoretical model for examining import refusals is suggested using the negative binomial counting process. The reputation spillover effect, was divided into two spillover effects of 'neighbor reputation' and 'sector reputation'. Results show that there exists a neighbor reputation spillover effect. It can be said if there was a import refusal of the same product from neighboring countries in the preceding year, the home country have a possibility to experience import refusals of the same product. Therefore, it is interpreted that neighboring countries have good standard compliance can help home countries to effectively reach the target markets. Our findings have a important policy implication for ASEAN exporters of fish and fishery products.

This study presents a comparative analysis on mackerel distribution process and price formation process, and investigation of price and margin between traditional markets and Large-scale discount store distribution channel. Through this, the study investigated distribution efficiency of each channel, and examined whether a difference of distribution efficiency leads to a difference of performance through the investigation of a difference of function and role between members of a wholesale market and vendor of Large scale discount store. The following are the results of this study. As a consequence of investigating supply and sum by distribution channel of mackerel, it appeared that mackerels shipped from port market are distributed into 9 consumption sites(Wholesale market, Large scale discount store, Institutional Food Service, etc.). In the comparison of distribution efficiency between traditional retail store and Large scale discount store 52.0% margin is formed in traditional retail store distribution channel and 43.1% margin is formed in Large scale discount store, and a distribution cost rate consists of 19.4% cost in a traditional retail store for fishery products and 18.1% cost in a Large-scale discount store. To analyze a difference of performance, the study examine a difference of role and function between vendor and Wholesale market company, wholesaler and middleman. Wholesale market company and middleman of wholesale market for consumer have slightly high or similar score in collection function, sorting function, evaluation function and financial function which are traditional and original. However, it was confirmed that vendor has a better score in other functions, that is, newly-demanded functions(ex : market frontier function, product development function, Integral Distribution Function, etc.).

Instant noodle is one of the most popular foods in Korea. The objective of this study was to examine the association of instant noodle consumption and food and nutrient intake among children and teenagers in Korea. We used dietary data from 24-h recall of 1,748 subjects aged 7-19 years who participated in the 2005 Korea National Health and Nutrition Examination Survey. Those who consumed instant noodle once or more during the survey period were categorized as "instant noodle consumer (INC)" and were compared for food and nutrient intakes with the others (non-INC). The average age of the INC was 13.4 and that of the non-INC was 12.4; girls consumed more instant noodles than boys (p < 0.05). There was no significant difference in BMI between the two groups. With the exception of grains, as compared to the non-INC, the INC consumed significantly less amounts of potatoes, vegetables, mush-rooms, fruits, spices, seafood, and milk and dairy products. With respect to nutrient intakes, the INC-group showed significantly higher nutrient intakes of energy, fat, carbohydrate, sodium, thiamine, and riboflavin; however, as compared to the non-INC-group, the INC-group showed significantly less intakes of calcium, niacin, and vitamin C. The overall result suggests that consuming instant noodles may lead to excessive intake of fat and sodium, but it may cause an increased intake of thiamine and riboflavin. Therefore, nutrition education that helps children and teenagers choose a balanced meal while consuming instant noodle should be carried out. In addition, manufactures of instant noodles should consider nutritional aspects in product development processes.

This study examined the development of a low-salt fermented seafood product using an ascidian (Halocynthia roretzi), and the optimum processing conditions and quality characteristics of the low-salt fermented ascidian (LSA). The optimum processing conditions for the LSA were as follows. The ascidian was shelled and its muscle sliced into 5 mm widths. This was soaked in a 10% salt and 1% sodium erythorbate solution for 20 min. The solution was drained and then the muscle was soaked in 0.1% sodium bisulfite solution for 1 min. To this was added a 1:1 mixture of anchovy sauce and rice gruel, and it was fermented at $5^{\circ}C$ for 15 days. The moisture content and salinity of the LSA were 75.0-75.4% and 8.0-8.5%, respectively. During salt-fermentation at $5^{\circ}C$ for 20 days, the amino-N content of the LSA increased, and the texture softened gradually. The viable cell counts in early salt-fermentation were $4.2-4.5{\times}10^4CFU/g$, and this decreased gradually. The ratio of saturated fatty acids tended to increase in early salt-fermentation, while that of polyunsaturated fatty acids decreased slightly. Chemical experiments and sensory evaluation showed that the dipping treatment in 1% sodium erythorbate solution and 0.1% sodium bisulfite solution resulted in a good color and prevented browning of the salt-fermented ascidian meat. Moreover, adding anchovy sauce and rice gruel mixture improved the flavor of the LSA.

This study was conducted to prepare salmon patty using muscle separated from salmon frame (SPFM) and to investigate the food component characterization. When compared to salmon patty with fillet muscle (SPM), SPFM was lower in the moisture content, while it was higher in crude lipid content. However, no differences in the ash and protein contents between SPFM and SPM were found. Compared to SPM, the Hunter color value in cross section of cooked SPFM was higher in a and $\Delta$E values, while the color was lower in Land b values. Trichloroacetic acid soluble-N content of SPFM was 279 mg/100 g, which was insignificantly different (P>0.05) compared to those of SPM and commercial patty. The hardness of SPFM was 0.44 kg/$cm^2$, which was insignificantly different (P>0.05) compared to that of SPM, while was higher than that of commercial patty. The major fatty acids of SPFM were 16:0 (16.5%), 18:1n-9 (29.2%) and 18:2n-6 (26.1%). The 20:5n-3 and 22:6n-3 were also detected in high composition. The total amino acid content of SPFM was 16.6 g/100 g, which was similar to that of SPM. However, the total amino acid of SPFM was 14% higher than that of commercial patty. From the results of the mineral content, SPFM was higher than that of SPM in Fe and Ca, while the K in SPFM was lower. According to the result of sensory evaluation on the color, flavor and taste, no significant differences in all sensory items between SPFM and SPM were found.
