Clam, Tapes japonica, has been widely used and occupies an important position in the markets. More than thirty kinds of fermented fish and shellfish are presently available in the markets in korea. This study was attempted to establish the basic data for evaluating the taste compounds of the clam. The free amino acids as taste compounds during the fermentation of the clam, Tapes japonica, were analyzed by an amino acid autoanalyzer. Alanine (17.0%), glycine (15.5%), taurine (13.9%) were high in amount in the fresh clam and then glutamic acid, arginine, tyrosine, asparagine, lysine, threonine, serine and leucine were the next in order. Such amino acids as methionine, phenylalanine, histidine and cystine were low in amounts. The total free amino acid nitrogen in the fresh clam was 45.5% of its extract nitrogen. During the fermentation of the clam, the kinds of the free amino acids were the same with the fresh samples although the amounts were changed. It is believed that glutamic acid, aspartic acid, glycine, alanine, lysine, and leucine may play an important role as the taste compounds in the fermented clam.

The pharmacological effects of hydrocooked(110oC, 5 hours) extracts of Bastard halibut have been investigated. All of the hydrocooked extracts showed the measurable contractile effect on the isolated rat duodenum and decreased the normal blood pressure in anesthetized rat. The hydrocooked extracts also exhibited a dose dependent relaxation on the isolated rat aorta precontracted with phenylephrine. Only RM 60 fraction of these extracts had the cytotoxic effect against MCF7 cell(human breast adenocarcinoma cell line), but the other fractions showed neither antibacterial activity nor antitumor activity. Although fish extracts fed group of rat maintained their original body weight, there were no notable changes in the hematological parameters, except that the levels of high density lipoprotein was significantly increased. These results suggest that the hydrocooked extracts of bastard halibut may contain a variety of bioactive materials.

Foreign body (FB) ingestion is a common health problem that affects children more than adults. According to gastroenterologists' guidelines, the management of FB ingestion differs slightly between adult and children. This review aimed to compile adult and children guidelines and establish an understandable association to reveal the requirements and timing of the endoscopic procedure, which is the most effective and least complicated technique for gastrointestinal FBs. Coins, pins, and chicken and fish bones have been the most commonly ingested FBs. However, with their increasing use in recent years, large batteries with lithiumion conversion, stronger magnets composed of rare earth metals, such as neodymium, and superabsorbent objects have become the most morbid and mortal, necessitating new management strategies. Although the approach to gastrointestinal FBs is controversial, with different treatment options available in different disciplines, many studies have demonstrated the efficacy and safety of endoscopic procedures. Many factors influence the timing of endoscopy, including the nature, size, and location of the ingested object and the patient's clinical condition.

The increased number of elderly in Korea presents great challenges for community nutrition programs. Strategies to enhance elderly nutrition are needed, as well as dietary advice that are reality-based and tailored to the need of the elderly. The purpose of this study was to evaluate the overall effectiveness of an elderly nutrition improvement program(ENIP), by assessing changes in nutrition knowledge, attitudes, and behavior after program completion. ENIP was conducted in Suwon for 4 months in 1998 at 5 centers for the elderly. The program provided individual nutrition counseling and brief biweekly group education sessions. To stimulate participation and motivation, the elderly in two centers were served free milk packs(200ml) three time a week during the program(milk＋education group), and the elderly in 3 other centers were served yoghurt on the program day(education group). Altogether, 102 subjects finished the program(milk＋education group 67 ; education group 35). Data about nutrition knowledge, dietary attitudes, diet records(24 hour recall) and dietary habit was collected before(baseline) and after the program(follow-up). The Drop-out rate for the milk＋education group(2.9%) was significantly lower than that for the education group(30.0%)(p<.001). The Nutrition Knowledge fo females milk＋education group increased significantly after the program, but no significant differences were observed in other groups. Over 60% of all the elderly showed positive responses to the healthy eating attitudes. Energy, protein, vitamin A, riboflavin, Calcium and Potassium intakes improved in the male milk＋education group. The Vitamin C intake improved in the male education group. Energy and vitamin A intakes improved in the female milk＋education group and energy, vitamin A, thiamin, riboflavin, niacin, Ca nad P in the female education group. A stepwise multiple regression analysis was performed to examine the effects of food intake changes on overall nutrient quality. For all elderly, the fish intake explained 12.6% of the variance, followed by candy intake and vegetable intake(model $R^2$=19.6%). Dietary habits such as meal time regularity and salty food reduction were markedly improved in both groups. Sixty-one percent of the milk＋education subjects stated their participation was voluntary and active, while 51% of education subjects did. Sixty four percent of the subjects stated their interest on diet increased remarkably through program participation. Considering the results, it is conjectured that ENIP had a great impact on nutrient intake, dietary attitudes and habits. Milk supplement showed no direct effects on elderly nutrition improvement, but it encouraged the program by reducing drop-out rates and inducing voluntary participation. Therefore milk supplement could enhance the community nutrition education program. Moreover it is strongly suggested that the ENIP be expanded to other communities.

The purpose of this study was to evaluate the preference trend of children in the child-care centers in relation to certain environmental factors such as size of the residing town. This evaluation was conducted using questionnaire survey where the mother of each child was required to complete a preference questionnaire including 83 food items. Statistical data analysis was completed using SAS package program. The results of this survey showed the followings : 1. Generally, the preference level of the children living in large cities were higher than of medium cities except in case of vegetables, while the preference level of the children living in large cities were higher than those of rural area except in case of hard-boiling(jorim) and vegetables. The subjects showed high preferences to bulgogi(4.53), pork-cutlet(4.52), fried chicken(4.51), jajangmyone(4.45), kimgui(4.43), roasted fish(4.31), roasted ham(4.13). 2. There was a tendency that a la carte, bread and noodles received higher preference scores. Items of Korean style soup attained higher preference scores than stew(ggigae). The preference scores of fired, broiled or pan-fried items(jun) were higher than those of other items such as seasoned vegetables(namool). 3. The preference scores of children (routinely or occasionally) skipping breakfast or supper were generally low. There was no significant difference according to the existence of mother's job except in case of steamed or pan-fried items, provided that the preference scores of the size of the monthly income of the household except stew, provide that the preference scores of the children whose household had lower income were slightly higher in general.
