The purpose of this study was to estimate the preference, intake frequency and eating behavior for kimchi as well as analyze the differences by gender among fourth to sixth grade students (n=410) in a Chungnam region. Approximately 64% of the students liked the spicy taste of kimchi, 75.9% liked the saltiness, and 48.5% liked well-fermented kimchi. The disliking factors of kimchi were its sour taste (38.5%), strong scent (20.1%), and salty taste (15.4%). The most preferred type of kimchi was Baechukimchi, followed by Kkakduki, Yeolmukimchi, and Chonggakkimchi. Further, the most frequently consumed type of kimchi was Baechukimchi, followed by Kkakduki, Chonggakkimchi and Yeolmukimchi. Oisobaki, welsh onion kimchi, sesame leaf kimchi, Gatkimchi, Nabakkimchi and Baekkimchi were rarely consumed. About 34% of the students consumed 5 to 7 pieces of kimchi per meal, and 84.1% enjoyed eating kimchi, mostly because of its good taste (61.3%). The reason for not eating kimchi was because other side dishes are more delicious (30.2%). About 80% of the students responded that they prepared kimchi at home. Moreover, 74.3% of the students eat kimchi much more at home than at school. Improvements to be made for kimchi at school were as follows: less salty (34.9%), less spicy (27.6%), and sweet (22.5%). In conclusion, students enjoyed eating kimchi because of its good taste. Further, they showed preference for Baechukimchi, Kkakduki, and Yeolmukimchi and consumed them frequently. Because kimchi appears to be more preferred and more frequently consumed, it is necessary to develop a menu using kimchi along with the proper eating guidance for helping students consume various types of kimchi at school or at home.

The kimchi refrigerator is the electric home appliance which is used for the maturing and preserving of the kimchi in domestic and foreign market. The kimchi refrigerator is composed in 3 main parts as insulation. kimchi container, machinery room. The heat exchanger of kimchi refrigerator is made of aluminum and the other parts are made of steel and polymer. Also, kimchi refrigerator is expensive and heavy as compared with same class of refrigerator until now. In the present study, the possibility to replace heat exchanger from aluminum to thermal conductive plastic was analyzed and experimented. The thermal conductive plastic has $10{\sim}100$ times heat conductivity than that of normal plastic. It is known that heat transfer process is dependent not only conduction but convection or radiation. Thermal conductivity of the applied material in this research is over than 2 W/mK, thermal conductivity doesn't play a vital role on heat transfer. In this study, temperature is the most important parameter on the kimchi refrigerator and the temperature of kimchi refrigerator's heat exchanger was measured and compared with the temperature calibrated by CFD analysis on the inside wall of the kimchi refrigerator. It is important to keep constantly the inside temperature of the Kimchi refrigerator. Besides numerical analyses for the new thermal conductive plastic for heat exchanger were executed with the various height of evaporation tube. A series of experiments were conducted to compare the performance of the two heat exchanger made of aluminum and thermal conductive plastic at the same condition and certified the possibility of the thermal conductive plastic. According to these results, it was confirmed that the conventional aluminium heat exchanger can be replaced by thermal conductive plastic successfully.

To estimate the amount of daily salt intake by source of food and urinary sodium excretion, a dietary survey was conducted from August 27th to September 3, 1980. The salt concentration of six kinds of food was measured. The families of 25 womens' club leaders and 25 families of hypertensive patients were studied after they had been given a short course of education on lowsalt diet. The results were as follows: 1. The average amount of high-salt foods eaten daily by the study group were as follows: 4.5 Gm. in the form of table salt 16.8 ml of home-made soy sauce 6.20 ml of commercial soy sauce 11.9 Gm. of home-made red-pepper bean paste 12.0 Gm. of home-made soy-bean paste 120.7 Gm. of Kimchi 2. The average NaCl concentration of each food was as follows: 99.5% in table salt, 22.5% in home made soy sauce, 11.9% in Commercial soy sauce, 6.8 Gm% in home made red pepper bean paste, 9.2 Gm% in home-made soy-bean paste and the average concentration of various kinds of Kimchi was 2.7 Gm%. 3. The total amount of daily salt intake per adult was calculated as 14.3 Gm. By sources of food 4.5 Gm from table salt, 3.9 Gm from home-made soy sauce and 3. 3 Gm from Kimchi were taken daily Three other kinds of food were also minor sources of salt intake.4. The average amounts of individual daily salt intake were not significantly different between the hypertensive group and the normotensive group: the median of the normotensive group (11.7Gm.) was significantly lower than that of the hypertensive group (14.9Gm.). Therefore the womens' club leaders appeared to respond more quickly than the hypertensive group after low-salt diet education. 5. The average amount of sodium excretion in the 24 hour urine specimen was 234.7 mEq. From this finding the daily NaCl intake was estimated to be 15.8Gm.

In the present study, an attempt was made to observe the effect of calcium-sources and preservatives on Kimchi fermentation. After pre-fermentation at room temperature for 16 hours, each Kimchi was stored at 4$^{\circ}C$. Changes of vitamin contents(vitamin C, thiamin, riboflavin and $\beta$-carotene) during the fermentation of Kimchi were determined. It was also attempt to relate the fermentation of Kimchi with the changes in chemical and organoleptic characteristics, such as pH, total acidity and reducing sugar. The findings were summarized as follows; 1. During Kimchi fermentation, the pH decreased steady and total acidity increased slowly in the follow order: K-Sorbate+acetic acid, k-Sorbate, Ca-Lactate and Control. the lower of pH and the higher of total acidity, the less of reducing sugar was remained. 2. changes of total vitamin C and reduced ascorbic acid contents during the Kimchi fermentation did not differ significantly from each other. At the begining of fermentation, Kimchi samples contained 20~25mg/100g of total vitamin C and 5~14 mg/100g of reduced ascorbic acid. In the final stage, however, 15~19 mg/100g of total vitamin C and 1~3 mg/100g of reduced ascorbic acid were remained. 3. The contents of thiam in and riboflavin were 30 to 42 meg/100g and 50 to 67 meg/100g at the initial stage, respectively. They increased with the degree of maturity (approximately 2 times of the content of the initial stage) and then gradually decreased. The content of $\beta$-carotene was found to be decreased with the degree of maturity. 4. The results of sensory evaluation indicated that Kimchi added with Ca-Carbonate, Ca-Carbonate+acetic acid and Ca-lactate were better than Control.

The purpose of this research is to get basic information needed for the development of special kimchi for the elementary school students. A questionnaire was used to investigate the consumption and attitude of the students when they having kimchi in the school meal service. The subjects consisted of 426 elementary school students(212 boys and 214 girls) in Seongnam. The collected data were analyzed by SAS package. The frequency of having kimchi was as follows. 52.1% of the students eat kimchi in every meal time, and 97.4% eat more than once a day. However, 54.0% of the students consume more than 5 pieces($2.5\times3.0 cm$) of kimchi per meal while 17.6% 1~2 pieces. They eat more kimchi at home than at school, and the main reason is that kimchi at home is 'more tasty'(79.1%), 'more safety'(29.1%) and 'less hot and salty'(19.2%). Baechu kimchi was found to be the most favorite one in the school meal service, followed by kkakdugi, yoelmu kimchi, chonggak kimchi, oi kimchi and nabak kimchi in order. Students wanted to added apples, pineapples, pears, oranges, shrimps, cucumbers and crab flavored fish paste to kimchi. Students' most favorite foods made with kimchi in the school meal service were Kimchi bokgumbab, Kimchi mandu, Kimchi jjigae, Kimchi jumukbab, Kimchi gimbab, Kimchi bokgum, Kimchi bibimbab, Kimchi hamburger and Kimchi dongas in order. Higher grade students and boys showed higher preference for the variation foods than lower grade students and girls.

This study was performed with 482 subjects(278 boys and 204 girls in Seoul and Kyunggido area) to find out the attitude and eating behaviors about Kimchi on Korean young generation. General characteristics about subject and attitude and eating behavior were surveyed by self-developed questionnaires. 85.9% of the subjects were nuclear family type and 49.9% of respondent's mother had full-time job and 96.1% of subjects were middle or upper economic status. The preference for Kimchi, 60.4% of respondents answered that they liked Kimchi. According to grade, the rate of preference about Kimchi was significantly different, higher grade students were found higher preference on Kimchi : 64.4% of middle and 70.4% of high school students liked Kimchi. The eating patterns of Kimchi, up to 60% of respondents answered they ate Kimchi in every meal time, which suggested that it was still an important side dish in Korean meal among teenagers. The eating behaviors on Kimchi, $85{\sim}90%$ of respondents answered that they preferred Kimchi in meal time. Baechu Kimchi(chinese cabbage Kimchi) and Gakdugi(radish cube Kimchi) was highly preferred. And their preference of food which made from Kimchi (such as Kimchi fried rice, Kimchi stew, Kimchi pancake) was highly evaluated. 65.6% of residents pointed out that 'Kimchi is very nutritious food'. The respondent's structure of value on Kimchi were not significantly difference between sex and age. But it was significantly difference(p<0.01) between the groups with preference and familiarity on Kimchi. The group had higher preference and familiarity on Kimchi agreed to the positive values about Kimchi. These result suggested that various kinds of Kimchi should be developed for young generation to meet their taste and also continuous nutrition education about traditional food especially Kimchi should be promoted at home and school.

The purpose of this study is to investigate the management of Indigenous fermented foods during the period of economic development starting from 1960 until now, and to specify their correlation, while paying special concern to the variables of social change such as the increase of people's income, ceaseless migration of population, change in the family structure, heightening up of the educational level of women and the resulting increase of chances for getting employment, all of which may affect the management of Indigenous fermerted foods in korean families. The result is as follows. Basic seasonings and dishes such as soy bean sauce, red pepper paste, pickled seafoods, and Kimchi, are inclined to be bought as readymade products or provided by relatives in case of many nuclear families rather than made at home, which is a traditional way of home life. However, Kimchi and basic sauces or redpepper paste still show high rate of being made at home. Social variables which affect such tendency are the number of family members, the age and educational level of housewife, and the type of residence.
