This study was investigated seafoods provided by school food service and students' preferences for and perceptions of seafoods. The subjects were 275 second grade(age 14-16) students of 4 middle schools in Gyeongnam. The results were as follows. The most main seafoods intake place was 'home'(65.8%). 'School food service' took meaningful ratio(20.7%) of students' seafoods intakes. In the intake amount of seafoods provided by school food service, 'all' took 22.5%(male 31.6%, female 14.1%), 'more than provided' took 1.5%(male 3.0%, female 0%). Male students ate seafoods more than female students did(p<.001). In seafoods providing frequency, '2~3 times a week' took 74.5%, '4~5 times a week' took higher ratio in males' schools, while '0~1 times a week' took higher ratio in females'(p<.05). In perceptions of seafoods, most subjects had positive perceptions as 'good for health'(3.95), 'various kinds'(3.75) except 'good peculiar smell' got smallest point(2.85). In means of learning about seafoods names, 'by looking at everyday menu' took 64.6%. In taking nutrition education, 'no nutrition education' took 69.5%. In preferences for seafoods using 5-point scale, males' preferences were higher than females'(p<.001). 48.1% of males got higher than 4 point, while 14.1% of females did. In improvement measures of seafoods, 'provide various kinds'(47.3%) took highest ratio. In preferences for seafoods by seafoods kinds, preference for 'crustacean' was highest while preferences for 'shell fish' and 'fish' were relatively low. Both male and female students highly preferred laver, shrimp, swimming crab, small octopus, fish cake and tuna canned goods. Male students' preferences were higher than female students' for most kinds of seafoods. In preferences for seafoods by cooking methods, preferences for 'grilled', 'stir fried', 'pan fried' were relatively high, 'braised', 'deep fried', 'steamed' were relatively low. Males' preferences were higher than females' for every cooking method except 'steamed'.

This study was conducted to figure out the nutritional nature of seafoods categorized according to the medicinal effects and the usages introduced in Lim-Won-Sib-Rheuk.-Ji, one of the well-known encyclopedias published during the Chosun Dynasty. They were compared with those introduced in other cooking books in order to find out how they were used in the diet of real-life. The seafoods of the book were first categorized into the fish 20, the mollusk 5, the crustacea 4, and the shellfish 7, and reptile according to the biological taxonomy, and then each one was reviewed in terms of the taste and the food-nature. Generally, the fishes had the sweet taste; the crustacea and the shellfish the salty or sour in addition to the sweet taste; none of them were bitter or hot. Most of them had the mild nature; seven of them were regarded as warm; four as cool; one as cold from the standpoint of the traditional medicine. The food-nature of seafoods was closely related with the medicinal effects on the human body. These seafoods were characteristically used in daily dietary life as well as the medical applications; used as the side-dishes rather than the main-dishes. The cooking methods of boiling, steaming, and baking were preferred to drying and stewing. The preservation methods favored were the fermentation, drying and salting. These cooking and preservation methods were believed to reflect the nature of the seafoods to manifest the medicinal effects.

Thirty-six environmental isolates of Vibrio vulnificus obtained from seawater, sediments, and raw seafoods, and 18 clinical isolates from Vibrio septicemia patients were typed by restriction endonuclease digestion profiles (REDP) of genomic DNA with SfiI. The results revealed a high-level of variation in REDPs, indicating a vast genomic diversity among V. vulnificus strains. Genetic relatedness of the strains showed similarities ranging from 10％ to 100％. Different REDPs for isolates from various raw seafoods were obtained, and clustering of strains according to type of seafoods was not observed. In contrast, clinical isolates of V. vulnificus showed higher similarity to one another, and could be subdivided into one separate group. The difference in REDPs of the V. vulnificus isolates from clinical origin and from raw seafoods substantiates the previous observation that only a single type of pathogenic strain was involved in each human infection, despite the numerous genetically polymorphic strains found from implicated oysters.

Pyropia, economic red algae species, have been cultivated in Korea (referred to as 'gim'), Japan ('nori'), and China ('zicai') for over 300 years. Vegetable seaweed Pyropia species are sold in the public markets in various forms as commercial seafoods. In Korea, two kinds of Pyropia seafood made with species of Pyropia and Ulva (sea lettuce, referred to as 'parae') are also sold. These are referred to as 'parae-gim' (with Pyropia spp. and U. linza) and 'gamtaegim' (with Pyropia spp. and U. prolifera). There is currently no method for identifying the seaweed species that comprise Pyropia seafood products. Therefore, we developed novel molecular markers to identify Ulva species in commercial Pyropia seafoods. Based on rbcL molecular markers, we identified informative characteristics to discriminate U. linza and U. prolifera as seafood ingredients. Moreover, PCR with 3'-end mismatch primers successfully isolated the specific rbcL sequences of U. linza and U. prolifera from Pyropia seafoods. Therefore, our novel molecular markers will be useful for identifying the ingredient species of commercial seafoods.

The purpose of this study was to investigate utilization and storage management practice of the frozen and refrigerated foods in school foodservice. 222 dietitians employed in school foodservice were surveyed. In school foodservice, the refrigerated stock farm products and seafoods (78.3%) were more used rather than frozen products (47.5%). According to school foodservice characteristics, the refrigerated meats including dairy products were more frequently used in elementary and middle schools than high school foodservice. On the other hand, the foodservice in high school used more frozen seafoods and processed foods than elementary school did. The data also showed a tendency for the contracted foodservice using more frozen meats and seafoods rather than refrigerated products when comparing with the self-operated foodservice. In terms of receiving conditions, storage methods and storage time, the result indicated that frozen or refrigerated products were often delivered at inappropriate temperature. Especially some products which were needed to be shipped and stored at refrigerated temperature such as mollusks, were delivered and kept at room temperature. The most frequently used thawing method were running water (56.9%), however, the frozen products were often sitted at room temperature for the purpose of thawing. According to the results, several inappropriate handling processes for frozen and refrigerated products were found in school foodservice. In order to improve handling process for frozen and refrigerated products, recognition of food handlers' weakness about storage and distribution, development of radical standards for receiving conditions, storage and thawing methods should be debated.

This study is aimed at examining the status of seafoods intake and preference to actively use the seafoods with high nutritional values and preference. For this purpose, this study conducted a questionnaire survey. The demographic features of the respondents are as follows: male and female high school students were 50%, respectively; first graders were 33.3%, second graders were 35.0% and third graders are 31.7%; the primary dietary-care giver was mother in 80% of the respondents. The survey results on seafood intake at home showed that the most frequently responses to the question of the degree of liking seafood were 'on average' and 'like it', respectively in order. The reason for preferring seafood is 'because it tastes good' in 43.7% of the respondents. Both male and female respondents answered they like seafood for its good taste. With respect to the degree of preference for the seafood provided from the school meals, there were more students who like it than those who do not like it. The most frequent reason to ingest seafood in the school meals is because 'I want to eat it' followed by 'because parents push', 'because friends eat it', 'because health-related TV programs recommend it', respectively in order. The most preferred seafood in the school meals was fried shrimp and the most disliked one is the boiled warty sea squirt. The above results collectively suggest that the preference level for seafood is low and the most preferred one is fried seafood. It is suggested that the nutritionists need to actively develop menu for the students to ingest more various seafoods.
