The purpose of this study was to investigate the dietary life about Kimchi of the housewives. Self-administrated questionnaires were completed by 322 housewives in Wonju area. The results were as follows: In the point of housewives' domestic duties, over 50% of housewives took care of their domestic duties alone, and the rate who learned how to manage domestic duties from their mothers before marriage decreased as the age got younger. 77.6% of housewives responded that both man and woman could manage a dietary life at home in the future, and the rate of such response was higher as their educational careers were higher and they were younger. In the point of housewives' basic situation about Kimchi, the rate of housewives who knew how to prepare kimchi was high as they were older, and the holding rate of a refrigerator for Kimchi was high as much as 72.4%. In the point of preparation for Kimchi, the rate who made Kimchi by themselves was high, but the rate of preparing Kimchi by their parents for them was higher in the twenties. Frequency of making Kimchi, an amount or a kind of Kimchi were notably different according to housewives' age, a type of their family, the number of their family, and their having a job or not. Housewives' opinion of a market kimchi was that it was expensive, and not sanitary, and rate of purchasing Kimchi was also low. In the point of the prepartion method of Kimchi for the winter, the rate who gained Kimchi from their parents was higher as they lived in an apartment, and had a nuclear family, and had the lesser family members. In an amount of Kimchi prepared for the winter, 11∼22 heads were 23.9% and 21∼30 heads were 21.9%. In the point of the method preparing Kimchi in the future, 53.8% of housewives responded that they would make by themselves, and 28.0% answered they would prepare or purchase. 77.4% of housewives answered that they would teach how to make Kimchi to their children. In conclusion, in housewives of Wonju area, wanted to make Kimchi by themselves and wanted their children to learn how to make Kimchi.

This study were comparison the quality characteristics of winter Chinese cabbage and investigation the physicochemical properties during Kimchi fermentation. External characteristics of three cultivars winter Chinese cabbage were compared, total weight of "Manpung" cultivar showed the heaviest in Chinese cabbages, but edible portion weight of "Seolwang" cultivar showed the heaviest in Chinese cabbages. Kimchi made of winter Chinese cabbage were fermented at 5$^{\circ}C$ for 40 days, of which pH, acidity, free sugar and organic acid were measured. The hardness of "Manpung" cultivar continued highly during the Kimchi fermentation at 5$^{\circ}C$. The pH and total acid in Kimchi fermentation, of the "Manpung" cultivar changed more than those of others. At the initial stage of Kimchi fermentation the major organic acid was citric acid, but lactic acid and acetic acid were increased rapidly during fermentation of Kimchi. The major organic acid of Kimchi fermented for 30 days was lactic acid, and the lactic acid contents of Kimchi prepared with "Manpung" cultivar was 6,796.6$\mu\textrm{g}$/g account for 69.6% of total organic acid.

In order to establish the basic scientific data on the fermentation characteristics of chonggak kimchi (CGK), we studied with CGKs prepared at different seasons and stored at various temperatures ($5{\sim}23^{\circ}C$). Changes in pH and acidity of CGK fermented at different temperatures were typical. However, acidity of summer CGK stored under $15^{\circ}C$ did not reach 1.0% since the amount of reducing sugar in the summer radish was lower by over 1% than the ones from the other seasons. Growths for Leuconostoc and Lactobacillus spp. over 8.0 logCFU/mL were observed in CGKs fermented above $10^{\circ}C$. Changes in Max G, cutting force, of CGK from different seasons were apparent. Max Gs for spring and summer CGK were decreased immediately right after storage while Max Gs for winter CGKs were increased slowly during storage. According to the results of sensory evaluation, CGKs revealed the highest overall acceptability when acidity of kimchi reached $0.7{\pm}0.1%$ under the given fermentation condition. However, CGK prepared with radish from winter or summer season tasted better than the one made in the spring. But the edible periods for winter CGKs were longer, compared with summer CGKs fermented at the same temperature. In conclusion, CGK fermented at $10^{\circ}C$ in the winter season gives a better taste with longer edible duration than the other CGKs.

1) In Seoul, it was known that the season for preparing Kimchies (fermented vegetables) for the winter was from the middle of November to early in December, in which the preparing rates of Kimchies in the middle of November, the end of November and early in December were 32.7%, 41.3% and 12.5%, respectively. The time that the largest quantity of them was prepared was about the end of November. 2) The average cost of Kimchies prepared for the winter for a family of four, five, six and seven was $10,000{\sim}15,000$ Won, $15,100{\sim}20,000$ Won, $10,100{\sim}20,000$ Won and $10,100{\sim}20,000$ Won, respectively, and the cost did not increase in proportion to members of a family. In case of the family of $6{\sim}7$, the cost for Kimchies showed a wide range compared with those for the family of $4{\sim}5$ 3) The main raw materials of kimchi for one person for the winter required $12{\sim}20$ heads of Chinese cabbages, $14{\sim}20$ roots of radishes, $4{\sim}7$ cloves of garlics and $300{\sim}500g$ of powdered red pepper. 4) The residents living in Seoul had prepared the several kinds of the pickles for the winter as follows; (1) Chinese cabbage Kimchi (98.9%), (2) Whole Chinese cabbage Kimchi (74.7%), (3) Kkakdugi (68.6%), (4) Dongchimi (66.4%) and (5) Chong-kak Kimchi (63.3%). It has, therefore. been considered that the five kinds of Kimchies mentioned above may be industrialized. 5) Uniqueness of the raw materials used for the most popular Chinese cabbage Kimchi was to use leeks, garlics, red peppers and gingers as spices, and it was also known that proper amounts of salted shrimp pickles and oysters was mixed to the Kimchies. Therefore, it had been considered that the characteristics of Chinese cabbage Kimchies for the winter had the hot taste with freshness. 6) For keeping the Kimchies during the winter about the half of the pickle jars was buried in the ground, and another half of them were wrapped in the straw bags or styropol and they were placed on the ground or kept in the basement, 7) In most case (80.9%), the salt concentration of pickling was adjusted by one's experiences, and only 19% of them was measured with the instruments. 8) Most of remaining kimchies were usually used for other cooks, but some of them were thrown away. 9) The ratio of the people who had ever bought the market Kimchies for their own edibility was 17.8% and most of them got it only in the spring and summer season. 10) About 18% of the residents living in the general houses in Seoul had ever bought the market Kimchies. It was also known that about 48% of the residents living in the general houses and about 79% of the residents living in the apartments wanted to purchase the market Kimchies if the production of the delicious Kimchies were industrialized. The season that the people wanted to get the market Kimchies was a little different each other among the residents. About 13.4% of the residents living in the general houses wanted to purchase the Kimchies during the summer, and 11.9% of them wanted to get it throughout the year. On the other hand, in case of the apartments, 25.2% of the residents wanted to get it during the summer and 24.4% of them wanted it throughout the year (4 seasons) and 19.9% of them wanted it during two seasons. The data mentioned above have shown that many residents hope strongly an industrial production of the Kimchies. It is also true that many residents living in both the general houses and apartments want to get the market kimchies throughout the year, and particulary during the summer season that most foods are very apt to be spoiled.

The material ratio for preparation of Kimchi in Seoul and Chung Cheong area and the pH, total acidity and NaCl concentration of properly fermented Kimchi were investigated. The kinds of Kimch prepared for the Winter were cabbage Kimchi, Kakdugi, Chonggak Kimchi, Nabak Kimchi, Dongchimi, Bossam Kimchi, and Paek Kimchi. The materials used for chbbage Kimchi were 20 to 25 of ingredients including salted fish and dhellfish. The material ratio of Kimchi was 71.9% of cabbage, 11％ of radish, 2.3-2.6% of green onion, 1.3-1.6% of garlic, 2.7-3.2% of powdered red pepper and 3.9-4.2% of salted fish. The kinds of Kimchi for Spring were cabbage Kimchi, Kakdugi, Chonggak Kimchi, Yulmu Kimchi and cucumber Kimchi. The amount of salted fish and shellfish used were decreased in Spring while vegetables of the season increased. The properly fermented cabbage Kimchi were measured of pH 4.2-4.5 and total acidity of 0.5-0.8%. The favorite concentrations of NaCl were found to be 2.3-2.7% in Winter Kimchi and 1.8-2.4% in Spring Kimchi and in watering Kimchi was shown low as 1.3-1.7%.

Fermented foods available in Korea may be classified into four groups, namely, fermented soybean products, fermented cereal products, fermented vegetable products, and fermented fishery products based on raw materials used. The representative fermented foods based on soybean are Kanjang(soysauce), Doenjang(fermented soybean pastes), and Kochujang(red pepper added-fermented soybean paste). Such fermented products are made using Meju(functioning as a starter and prepared by fermentation of steamed soybean mash) as an essential ingredient, and used widely as a soup base and/or in seasoning side-dishes for everyday meals year around. Excepting Sikhae, all fermented products based on rice and other cereal grains are of alcoholic nature. Takju (Makgeolli) used to be made using rice as the major raw material, however, mainly due to the shortage of rice in recent years, other cereals, such as, barely, corn, and wheat flours are also used to replace rice today. Owing to such changes in the raw materials. the popularity of Takju has been somewhat reduced, yet it is still widely consumed in rural areas. Although Chungju is a popular rice wine with superior qualify over Takju, the amount consumed is considerably limited. The highest qualify rice wine, Bupju, in particular, is made by a low temperature fermentation using glutinous rice. Kimchi is an unique fermented vegetable product of long tradition in Korea. Although it was for consumption mainly in winter season serving as a source of vitamins, today it is widely used throughout the year. Except Kkakdugi and Dongchimi, all of the fermented vegetable products contain salted Korean cabbage as an essential item, while they abound in varieties depending on material composition and methods of processing, and also on seasons and localities Next to Kimchi in this category is Kkakdugi made of raddish in popularity and quantity consumed. The four groups of fermented food products described above are reviewed in some detail and evaluated in terms of their nutritional significances, processes and microorganisms involved. and their commercial potentials. Jeotkal (or Jeot) is a name given to all fermented products of fishery origin. A number of Jeot can be prepared by adding salt and allowing fermentation to the raw materials such as shrimp, anchovy octopus, clam, oyster, etc.

Recently the rural Korea has been remarkedly changed of family and social value in accordance with the development of industry. The lower economic class made by social economic growth is widespread with increasing aged, specially odd pair family in rural. The purpose of this study was to investigate to help and keep improve health of rural lower economic class, family system by comparing and analyzing the dietary management, between pair and odd pair family, and to get the data helpful the right guidance for rural. The subjects 1870 collected in 9 provinces by sampling with probability proportional to size (PPS). Questionnaire about dietary habit, food cultivation, production and preservation survey was conducted by trained interviewers. The main results were as follows : 1) The characteristics of odd pair families, head of household was female(77%), over 65 years(84.9%), small family(1.76 persons) and lower education(male 7.5 years, female 3.1 years) status. 2) As the states of diets of odd pair family, having breakfast(87.1 %) but one or two kinds of side dishes(31.3 %) only possible to guess lower status of food intake balance. Nutritional supplements(21. 7 %) was lower than that of paired family. 3) The aspects of dietary habit of odd pair family, no instant foods(70.7%), no snack(38.4%) no dine out(69.2%) were common. 4) Dietary habit scores were 7.78 points of odd pair family compared 8.34 points of paired family. 5) Food purchase place of odd pair family was market(44.2%) but super-market(42.7%) of paired family. 6)In odd pair family, seldom traditional dish preparation(62.0%) but prepared winter kimchi(81.9%), comparing seldom traditional dish(38.6%) and winter kimchi(96.4%) in paired family. 7)The food cultivation state was surveyed, pepper( 42.2 %) and chinese cabbage( 43.9 %) were consumed after cultivation, but sesame(59.4%), bean sprout(90.2%), tofu(92.8%) and egg(93.3%) were consumed by purchase in odd pair family.8) Food cultivation score of odd pair family was 2.98/12points significantly lower than 4.50/12 points of paired family(p<0.01). 9) At the status of fermentation food production in odd pair family, Duenjang(72.1 %) and Gochujang(69.7%) Kanjang(68.3%) Kimchi(82.1 %) and Meju(68.3%) were high rate of production, but more frequently producted in pair family. 10) The score of fermentation food production of odd pair family was 8.57/12points but significantly lower than 10.24/12 points of pair family(p<0.0001). 11) Food preservation score 0.48/6 points in odd pair family was not significantly different than that of pair family(1.07/6points).

The purpose of this study was to develop functional lotus root bugak with plasma lipid reduction capacity by controlling the color of batter used for bugak preparation. Lotus root, nearly colorless, was selected to observe color effects. Gardeniae fructus (GF), Opuntia ficus-indica var. saboten (OF), and green tea (GT), which are colored yellow, red, and green, respectively, were used as coloring agents. Fermented glutinous rice was prepared naturally during winter season by placing glutinous rice and water (1:2, w/w) together in a crock pot for 7 days. Coloring materials (10%, w/w) were blended with glue made from fermented glutinous rice flour to prepare the batter. Cooked lotus root was then mixed with a 1.1-fold amount of batter (w/w) and dried at room temperature. Lotus root bugak (LRB) is pan-fried with un-roasted sesame oil, which is traditionally used as frying oil in Korea. Low-density lipoprotein receptor knockout ($LDLr^{-/-}$) mice (n=36) were fed an atherogenic diet (AD) containing various types of LRB (10 g%) for 10 weeks. Plasma triglyceride, total cholesterol, and LDL-C concentrations decreased significantly in mice fed LRB prepared with OF batter (OFB) and GT batter (GTB) (P<0.05). Protein expression levels of fatty acid synthase (FAS) and 3-hydroxyl-3-methylglutaryl coenzyme A reductase (HMGCR) in the OFB and GTB groups were suppressed compared with the LRB group (P<0.05). In accordance with the results on FAS and HMGCR expression, sterol regulatory element binding protein-I and II (SREBP-I and II), which are responsible for the regulation of FAS and HMGCR gene expression, respectively, were down-regulated compared to the LRB group (P<0.05). In conclusion, the plasma lipid reduction activities of OFB and GTB could be mediated through down-regulation of FAS and HMGCR mRNA expression via suppression of regulatory molecules, SREBP-I and II, in $LDLr^{-/-}$ mice.
