Background: The monitoring of pathogens of fishery auction markets is important to obtain safe fishery products regarding hygiene and sanitation. In this study, aerobic, coliform, Escherichia coli, and Vibrio cholerae were monitored in the fishery products and environmental samples obtained from fishery auction markets. Methods: The fishery products (flounder, octopus, skate, rock cod, sea bass, snail, monkfish, flatfish, comb pen shell, corb shell, conger eel, hairtail, croaker, and pilchard) were placed in filter bags, and the environmental samples (samples from the water tanks at the fishery auction markets, seawater from the fishery distribution vehicles, ice from wooden or plastic boxes, and surface samples from wooden and plastic boxes used for fish storage) were collected. Aerobic bacteria, E. coli, and coliform in the samples were enumerated on aerobic count plates and E. coli/coliform count plates, respectively. For V. cholerae O1 and V. cholerae non-O1 quantification, most probable number (MPN)-PCR analysis was performed. Results: Aerobic and coliform bacteria were detected in most samples, but E. coli was not detected. Wooden boxes were contaminated with high levels of aerobic and coliform bacteria in all seasons (spring, summer, and fall). During fall, V. cholerae non-O1 were detected in snails, hairtails, croakers, flatfishes, pilchards, plastic boxes, and water samples. Conclusions: These results indicate an increased prevalence of V. cholerae contamination in fishery products in fall, including food contact samples, which can be vehicles for cross-contamination.

This study was intended to develop traditional Korean soup recipe which can be used for food service and meet consumers' taste with a focus on clear soup such as clear radish soup, sea mustard soup, dried pollack soup, croaker soup, and backbone soup. The developed sample(S1) showed the highest level of overall preference among consumers. There were significant differences in sensory characteristics of the samples especially between S1 and others. The sensory characteristics of each soup showed a slight difference depending on the kind of soup, however, all items had an effect on overall preference. One of the standardized recipe to make broth was presented as follows: The ingredients for broth consists of the shank or brisket of beef(100 g), water(10 cup), spring onion(20 g), onion(30 g), garlic(10 g), salt(1 teaspoonful), and black pepper power(1/10 teaspoonful). 1) The meat part of shank or brisket is prepared. 2) The unfrozen meat is immersed in cold water for 20 min, whereby blood is extracted from the meat. 3) 10 cups of water are poured into the pan and boiled enough. 4) After water has boiled enough, the lump of meat with blood extracted is cut into 2 or 3 pieces and is boiled in the boiling water by high-intensity heat with the pan lid uncovered, and dirty foam is scooped out while boiling. 5) If the broth begins to be extracted, the intensity of heat is lowered for boiling for one hour or so, and then again boiled for 30 min with spring onion, garlic, onion and the like. If the broth is extracted enough, spring onion, garlic, onion, and others are removed from the pan. the broth is seasoned with salt and black pepper powder, and foam is removed by using fine mesh sieve or gauze. Then, 6 cups of clear broth is obtained finally.

This study examined the difference of dietary intake behavior between groups of adults aged >20 years with or without dyslipidemia, and comparing the various types of dyslipidemia, based on the Seventh (2016) KNHANES. Men showed higher rate for triglyceridemia and LDL-cholesterolemia than women and subjects in the age group 50-59 years exhibited the highest incidence of triglyceridemia, total cholesterolemia and HDL-cholesterolemia. The ratio of obese people was higher in most types of dyslipidemias. The top five foods in each group of cereal & grain, meat, vegetable, and fruit were selected for analysis, based on the food frequency. The dyslipidemia group showed higher intake frequencies for mixed grains, cabbage kimchi and leafy vegetable than the no-dyslipidemia group, and the group with high blood total cholesterol for mixed grains, apple, and cutlassfish-croaker. Group with high blood triglyceride showed higher intake frequencies of rice and mackerel-mackerel pike than the other groups of high blood triglyceride. No food showed significant difference in the frequencies between groups of LDL-cholesterol. Group with high blood HDL-cholesterol showed higher intake frequency of bibim-fried rice, deep fried chicken, stir fried chicken, apple, tangerine, banana and butter-margarine. These results indicate that people with high levels of blood total cholesterol are more concerned with food having health benefits than those with abnormal levels of other blood lipid. More information on dietary benefits need to be provided to patients having high levels of triglyceride, LDL-cholesterol and HDL-cholesterol.

백색육어를 배소한 경우와 배소한 시료를 저온에 저장 후, 단계적으로 가열처리했을 때 일어나는 산화에 의한 heme 화합물의 변화를 조사하였다. Heme 화합물 중 myoglobin 함량은 각시가자미나 조기 모두 180$^{\circ}C$에서 20분간 어피 제거육의 상태로 배소한 것이 상대적으로 감소폭이 컸으며 가열, 재가열에 의해서도 감소하는 경향이었다. Myoglobin의 감소 추세에 따라 metmyoglobin 함량은 역으로 점차 증가하는 경향이었으며, 배소온도가 낮을수록 또한 어피를 제거함으로써 생성된 metmyoglobin의 함량이 높았다. 총철 함량은 배소온도와 시간을 달리하여 처리하여도 두 어종 모두 생시료와는 함량 차이가 거의 없었다. 비 heme 철은 각시가자미의 경우 생시료에는 총철함량에 대해 약 $20\%$ 정도 함유되어 있었으나, 180$^{\circ}C$에서 20분간 어피 제거육의 상태로 배소했을 경우 생시료에 비해 약 2배 정도 증가하였다. 조기는 생시료에는 건물당으로 약 0.8mg/100g 함유되어 있었으나 배소, 가열 및 재가열과 같은 반복되는 가열과정에 의해 증가하였다. Heme 철 함량은 각시가자미와 조기 모두 비 heme 철의 증가에 반비례해서 감소하였으며 또한 배소시간이 길수록 그리고 어피 잔존육보다는 어피 제거육의 감소폭이 더 컸다.

This study was carried out to investigate correlation with food preference of subjects in three constitution groups on the view point of constitutional medicine. The constitutions of 124 college students(male 80, female 44) was classified by QSCC II method. Food preference of the subjects was surveyed in accordance with suggested foods for each constitution and was analyzed using Hedonic scale. The distribution of the constitutional revealed that Soeum individuals accounts 53%, followed by ; Soyang 19%, Taeum 28%. For men, sorghum, potatoes, beef, scombroid, oyster, saury, octopus, codfish, walleye pollack, shrimp, croaker, pineapple, eggplant, leek, pumpkin, toenjang, draft beer, diluted liquor, coffee, cocoa were statistically different in food preference score by sasang constitution(p<0.05). For woman, chicken, pollack roe, a walleye pollack, persimmon, jujube, melon, citron, celery, burdock, vinegar, bean-paste soup, draft beer, ginseng, honey were statistically different in food preference score by sasang constitution(p<0.05). Association of sasang constitutions and food thought to be harmful or healthy to each constitution was analyzed. But Food preference score of food thought to be harmful or healthy were not statistically different in score among sasang constitutions. This results suggested that food intake patterns of subjects were associated with sasang constitutional food in parts.

To investigate the materials in the preparation of kimchi for Koreans in the Commonwealth of Independent States(CIS) a survey was completed by 199 Koreans living in Moscow, Sahalin, Uzbekistan and Jazahstan, In the way to purvey the materials of Kimchi, the frequency to get all the materials of Kimchi in the markets is 74.7% on the whole and by regional groups the frequency is relatively high in Moscow and Kazahstan, For the main ingredients most respondents use Chinese cabbage, cabbage, or turnips. In general Chinese cabbage is used most, But the respondents who live in Moxcow and Kazahstan. For the main ingredients most respondents use Chinese cabbage, cabbage, or turnips. In general Chinese cabbage is used most, But the respondents who live in Moscow and Kazahstan. 쫴 are younger, or belong to higher emigrant generation, prefer cabbage kimchi. For the additional vegetables many respondents use carrots. For the seasonings, garlic, red pepper powder, and salt are added to Kimchi, but the use of ginger, whole seasame seed, and waxy rice paste is relatively low. The coriander, which is not added to kimchi in Korea, is used in Kimchi By above 80% of the respondents living in the three regions except Sahalin. It is considered to be due to the effect of the western dining cultural area. For the animal materials, 74.4% of the respondents add lightly salted fish to Kimchi and all toe respondents in Sahalin add salt-fermented sea food, the kind of which is mainly salt-fermented croaker. The reasons given for not adding salt-fermented seafood to Kimchi in the three regions except Sahalin, 59.9% of the respondents said it was because of the difficulty to purvey, 21.1% because of the fishy taste, and 16.8% because of not considering the addition of self-fermented sea food in Kimchi. The higher the emigrant generation of respondents, the less seasonings of strong flavor like garlic, red pepper powder, and salt-fermented sea food are used, and the more coriander is used. In the salting of Kimchi preparation, 97.8% of the respondents salt the main vegetables by soaking in brine and its concentration is controlled by experience.

Elderly with dementia in geriatric hospitals (EDGH) are highly dependent on hospital meals. This study evaluated the foodservices satisfaction and food preference of the EDGH. The survey was conducted on 104 elderly with dementia (21 males and 83 females) in 4 geriatric hospitals in Seoul and Incheon in November, 2016. Data were collected from interviews using a questionnaire that consisted of 6 questions for foodservice satisfaction and 24 questions (10 categories) for food preference. The data were analyzed using SPSS ver. 20.0. The satisfaction with taste, saltiness, texture, and variety in foodservices was good, but the satisfaction with the amount was not, and the reason for leaving food was its large serving size. The subjects preferred soft boiled rice, noodles, porridges, meats, fish, seafood, vegetables, and fruits. Among them, they preferred more janchiguksu, red bean porridge, beef, croaker, oyster, spinach, and banana. Regarding the cooking methods, they preferred soup, grill, and boiling, but not frying. The also preferred Chinese cabbage kimchi, but they did not prefer hard kkakdugi. They did not prefer milk because of diarrhea, but they preferred yogurt. Therefore, to provide a satisfying meal for EDGH, it is necessary to develop a friendly diet considering their food preferences.

I have studied historical transition process of fisheries industries, fisheries Institute in abreast of developing fisheries industries of west coast of Korea since 1910 year with regard to the Gogunsan Is. The results were summarized as follows. In 1910 year, fishery industry has been carried out shifting fishing gear e.g set-net in shallow waters, small stow net, small seine net adapting to the tophorgrapical feature, shape of coast, oceanic condition, however, the fishing gear and fishing method were undeveloped, so that, Japanese fishermen had been exploited fisheries resources penetrating the fishing ground. Most important species were lot of captured croaker, cod, spanish mackeral, sea abream, herring in coastal sea. nowaday, squid, anchovy, shrimp, crab, pompret were much captured. The species were captured in 18 century were not captured. It is rarely than that period. Fishereis aquatic culture had been not farmed till 1960 year, but sea laver, shrimp, crab, had been breeded 1970 year also, the fresh water fish e.g. eel, cat-fish had been breeded activately. The fisheries processing industry were composed of salt. icing, dry, method. the salted fish industry had been prevailed at Gangyng, Kwangchon, Kunsan, Julpo comparatively. The fisheries institute had been established at Kunsan at first, but institute established in other region had been abolished in a short time. This phenomenon was related with development of fisheries resources. The western coast fisheries industries had been wasted of decreasing of fisheries resources, variation of environment. Accordingly, the study of preserving the marine resources. educated man power who engaged in fisheries field have to accomplish. Sea was dying with reason of loss of mud in west coast factory waste, waste of life the increase of accident of sea polluted, each illegal fishing industry physical and chemical reason etc. in this respect, Kusan maritime college, fisheries developing agency, institute have to take important role for developing fishing industry.

Although scientist have been reporting recently that changes in ocean environment influence the species composition, movements, and growth of fish in Korea waters. Previous studies on fish vulnerability owing to climate changes are insufficient to explain the effect of fluctuating ocean environments on fisheries ground. In this study, we suggested a method for the assessment of fisheries sensitivity to various factors in ocean environments in Korean waters. To evaluate the fisheries sensitivity, catch data (Chub mackerel, Hairtail, Common squid, small yellow croaker) from National federation of fisheries cooperatives in Korea (1991-2017) and oceanographic data from Korea Ocean Data Center (KODC; 1960-2017) were normalized using the z-score method. Thereafter, the fisheries sensitivity was calculated using the difference between the catch data and the oceanographic data. Finally, the fisheries sensitivity was evaluated based on evaluation grade ratings. Result revealed that in the south sea, variability in catch data was obviously higher than environmental fluctuation (evaluation grade 1), indicating that catch variability in response to environmental change is most sensitive in the south sea among Korean waters in 2017. These results would be helpful for fishery management and policy for sustainable yield in Korean waters.
