This study examine the relationship between the intake of food conformable to each Sasang constitution and the recognition of irregular symptoms of health condition. The study subjects were 362 university students nationwide, classified by heir Sasang constitution. In terms of the intakes of conformable food and the symptom recognition, the number of multiple subjective symptoms tended to rise as the Soeum type digested the conformable food. As for the kinds of food, the Soyang type showed a significant positive correlation between the intake of cucumber namul and the symptoms of eyes and skin, but a negative correlation between the intake of Chongak Kimchi and the symptoms of the digestive system The Soeum type showed a significant positive correlation between multiple subjective symptoms and the intake of Gatkimchi, fernbrake namul, naeng-i soup, naeng-i namul, Korean leek Kimchi, crown daisy namul, and curled mallow soup, a significant positive correlation between the symptom recognition of the respiratory system and the intake of fried flatfish, and chicken gomtang but a negative correlation between the symptom recognition of the eye and skin and the intake of boiled eel. The Taeum type presented the a sigmificant positive correlation between multiple subjective symptoms and the intake of spaghetti, a positive correlation between the symptoms of the respiratory system and the intake of tuna salad, a positive correlation between the symptoms of the eye and skin and the intake of mafa tofu, spaghetti, and tuna salad, a negative correlation between the symptoms of the mouth and anus and the intake of codfish jiri, and a negative correlation between the symptoms of the respiratory system and the intake of tuna salad.

"Gyuhapchongseo" was published in 1809, and introduced the cooking method of the noble class in the late Joseon dynasty. The characteristics of the side dishes in "Gyuhapchongseo" are as follows. Firstly, red pepper was used as whole red pepper, shredded red pepper, powdered red pepper, or Korean hot pepper paste. Secondly, salt-fermented fish was used in some forms of Kimchi, including Sukbakgi, Dong A Sukbakgi, and Gyochimhae. Thirdly, to retain the juiciness of meat during roasting, meat was spread cold water on the surface, dipped into the washing water of rice or wrapped with wet paper. Fourth, to improve the visual effect of a dish, cooked foods were displayed with various color schemes, panfried foods with two tones (egg white and yellow) of color on each side and the use of radish pigmented with deep red color. On examination of the characteristics of food in "Gyuhapchongseo", I would suggest applicable practices for the present cuisine. The use of gravy produced from the boiling down of fish flesh could raise the nutritive value of Kimchi. In "Gyuhapchongseo", Yak po (semi-dried minced beef) is noted as being good for elderly people with bad teeth. A steamed dish with dog meat in Dong A in "Gyuhapchongseo" is made by hollowing out Dong A and putting a dog in it to cook the dog meat to well done in a fire made with the hulls of rice. This technique could be used to present cuisine for steamed and roasted dishes using food ingredients such as pumpkin, sweet pumpkin, and overripe cucumber.

Koryo(918-1352) made a certain progress in her culture and agriculture except the latter part of the era when the development in social economy were retarded due to military dictatorship and Mongol invasion. Despite of these external conditions, cultivations and kinds of horticulture foods were expanded With the help Of many king's agriculture first policy and the advancement in cultivating method . Among the horticulture foods, fruits such as peach, plum, Japanese apricot, apricot, cherry, pear, persimmon, pomegranate, crab apple, Jujube, grape, Chinese quince, walnut, orange, yuzu, chestnut, ginkgo nut(silvernut), pine nut, nutmeg nut, and fiat were crowed, and vegetables such as Chinese cabbage, turnip, radish, garlic, welsh onion, gynmigit, scallion, taro, malva, cucumber, white gourd, bottle gourd, water melon, eggplant, Japanese ginger, ginger and litchi were cultivated, while semi, water shieled and bamboo sprouts were taken in natural. Fruits were taken in natural or through dry, and particularly grapes were used to make wine, Flowers of Japanese apricots, some fruit trees, and chrysanthemum were also made into wine. Certain fruits were used as medicine owing to its medicinal nature. Vegetables were used to make Kimchi or to boil soup, sometimes they were dried to be kept in storage to be used in rare season and also used as medicine Increase in kinds of horticulture foods does not have any direct relation with the reform of social economy, but the fact that so many kinds of horticulture foods were cultivated and used in Koryo era shows that they elevated people's life and dietary culture.

The purpose of this study is to analyze the differences of food habits and food preferences between lower and higher grade students through the survey of elementary school students in Daejeon four elementary schools located in Jung-Gu and Seo-Gu in Daejeon are selected for this survey randomly and the completion of the questionnaires are according to grade. 1. Practical Analysis of Food Habits: For regular meals, the highest number of subjects skipped breakfast. It is being found that the girl students (81.61%) consumed more cooked rice than the boys (78.85%) and more boys (13.10%) ate bread or milk more than the girls (9.20%). The most important thing for the lower grades students (34.20%) when consuming is the nutritious foods, while the higher grades students (49.67%) consumed the set meals. During consumption, the highest number of the subjects watched TV or read books from time to time. More higher grades students (38.98%) preferred spicy and salty foods than the lower grades (22.09%). 2. Food Preferences: Between rice and noodles, most subjects preferred cooked rice (81.38%), Jajangmyeon (80.80%), Ramyeon (79.43%), and disliked bean-mixed rice (28.39%). For soups, Most students enjoy the Deokkguk. Majority of the subjects prefer meat and fried or steamed foods, and also grilled and pan-fried dishes. For the pan-roasted and fried dishes, most subjects did not enjoy the rhizome fry and sweet-pumpkin fry methods, and for vegetables, they did not like wild vegetable and seasoned cucumber (40.57%) The higher grades students enjoy the vegetables and salads more than the lower grades students. For Kimchi varieties, it is found that subjects like the cabbage Kimchi (69.66%) the most. There is little difference in food preference between the lower and higher grade students, but the rankings of food preferences are different according to various grades.

This study was conducted to investigate the side dishes preference of Korean food with 403 college students (197 males and 206 females) in Seoul using questionnaires. Regarding preference of soups, it was shown that male students liked $s{\breve{o}}ll{\breve{o}}ngt'$ang and beef soup and female students liked soybean paste soup. Male students had higher preferences for $s{\breve{o}}ll{\breve{o}}ngt'$ang, beef soup, dried pollack soup, and kimchi soup than female students (p<0.05). Both male and female students had the highest preferences for kimchi pot stew and soft-tofu pot stew, but the lowest preferences for fermented soybeans pot stew and frozen pollack pot stew (p<0.05). Stewed beef with soy sauce was preferred the most by both of them but female students had lower preferences for stewed bean with soy sauce and stewed pepper with soy sauce than male students (p<0.05). For the preference of panbroiled foods, stir-fried with marinated anchovy was disliked by both of them but stir-fried with marinated pork was shown to have high preference in male students and stir-fried with marinated kimchi was high in female students (p<0.05). Besides, roasted ribs, cucumber salad, and korean cabbage kimchi were preferred the most by both of them. But male students had higher preferences for roasted eel, grilled todok, roots of broad bellflower salad, mustard leaf kimchi, and white cabbage kimchi than female students (p<0.05).

In order to investigate the level of pesticide residues in the vegetables for Kimchi materials (Chinese cabbage, radish, red pepper, garlic and cucumber), which were produced in Andong district, organochlorine and organophosphur pesticide residues were analyzed using gas chromatography. The results were as follows; 1) In chinese cabbage, radish and some other vegetables harvested in early summer (June), organochlorine and organophosphur pesticide residues were detected in almost all of the samples tested, and a few of them showed a level higher than the organochlor APR(allowable pesticide residues). 2) Heptachlor, the soil insecticide was the most abundantly detected pesticide among the four organochlorine pesticides tested (Dieldrin, Endrin, BHC, Heptachlor) in this study. 3) Somewhat higher concentrations of organochlorine pesticides were detected in all kinds of sample vegetables harvested in late summer than in those harvested in early summer. And the frequency of organochlorine pesticide contamination was also increased, but the frequency of organophosphur pesticide contamination was decreased. 4) In the vegetable harvested in late autumn, level of organochlorine pesticide residues and frequency of contamination were markedly decreased and organophosphur pesticide residues (Diaginon, Malathion, Thiometon, EPN) were rarely detected. 5) The results of this study indicates that to take a lot of vegitables grown in summer was somewhat uncomfortable than those grown in autumn.

The bacteria B1-9 that was isolated from the rhizosphere of the green onion could promote growth of pepper, cucumber, tomato, and melon plants. In particular, pepper yield after B1-9 treatment on the seedling was increased about 3 times higher than that of control plants in a field experiment. Partial 16S rDNA sequences revealed that B1-9 belongs to the genus Pantoea ananatis. Pathogenecity tests showed non-pathogenic on kimchi cabbage, carrot, and onion. The functional characterization study demonstrated B1-9's ability to function in phosphate solubilization, sulfur oxidation, nitrogen fixation, and indole-3-acetic acid production. To trace colonization patterns of B1-9 in pepper plant tissues, we used $DRAQ5^{TM}$ fluorescent dye, which stains the DNAs of bacteria and plant cells. A large number of B1-9 cells were found on the surfaces of roots and stems as well as in guard cells. Furthermore, several colonized B1-9 cells resided in inner cortical plant cells. Treatment of rhizosphere regions with strain B1-9 can result in efficient colonization of plants and promote plant growth from the seedling to mature plant stage. In summary, strain B1-9 can be successfully applied in the pepper plantation because of its high colonization capacity in plant tissues, as well as properties that promote efficient plant growth.

Differences in dietary intake of Korean Americans (KA) by the length of residence in the U.S. were studied in relation to health and disease patterns in Michigan. Of 1860 questionnaires mailed, 637 (34.3%) responded with demographics, anthropometrics, self-reported disease patterns, lifestyle, and dietary patterns (93-item FFQ developed for KA). Complete responses were available for 498 people (263 men,253 women, aged 30-87 yr), who were then divided into three groups based on the number of years lived in the U.S.: 15y, 16-25y, 26y. Age-adjusted weight, height, BMI, and waist to hip ratio were within the normal ranges and did not differ among the three groups. Chronic diseases frequently reported in men and women (age-adjusted) included hypertension (14.4%, 14.1%), digestive diseases (5.4%, 8.5%), diabetes (3.6%,4.9%), and arthritis(3.3%, 12.5%), respectively. The length of residence in the U.S. was inversely associated with the age-adjusted prevalence of digestive diseases (12.4%, 6.5%, 0.4% in men, 13.0%, 11.7%, 0% in women). The length of residence was positively associated with health consciousness, receiving regular health care, taking supplements regularly, and exercising, while inversely related to smoking. The majority favored American foods for breakfast and Korean foods for dinner. Foods frequently consumed included cooked rice (w/other grains). kimchi, coffee (w/cream and sugar),bread (white and dark), citrus juice, milk (low fat and skim), lettuce and cucumber, apple, seaweed, and soda. Intake frequency of the Korean starch food group was inversely associated with the length of residence for both men and women (p<0.001), but not with the American starch food group. Fat intake did not differ by the length of residence in the U.S. The dietary changes were associated with the length of residence and chronic disease patterns for the first generation of KA, which should be further examined 'for the subsequent generation of KA.

Lactic acid bacteria (LAB) play an important role in dairy fermentations, notably as cheese starter cultures. During the cheese production and ripening period, various enzymes from milk, rennet, starter cultures, and non-starter LABs are involved in flavor formation pathways, including glycolysis, proteolysis, and lipolysis. Among these three pathways, starter LABs are particularly related to amino acid degradation, presumably as the origins of major flavor compounds. Therefore, we used several enzymes as major criteria for the selection of starter bacteria with flavor-forming ability. Lactococcus lactis subsp. lactis LDTM6802 and Lactococcus lactis subsp. cremoris LDTM6803, isolated from Korean raw milk and cucumber kimchi, were confirmed by using multiplex PCR and characterized as starter bacteria. The combinations of starter bacteria were validated in a miniature Gouda-type cheese model. The flavor compounds of the tested miniature cheeses were analyzed and profiled by using an electronic nose. Compared to commercial industrial cheese starters, selected starter bacteria showed lower pH, and more variety in their flavor profile. These results demonstrated that LDTM6802 and LDTM6803 as starter bacteria have potent starter properties with a characteristic flavor-forming ability in cheese.

This study was conducted to investigate the vegetable eating behaviors and preferences of elementary school students by stage of change for vegetable intake. The subjects consisted of 191 fourth and fifth grade elementary school students from Gyeonggi province. The stage of change for vegetable intake was categorized into three groups: precontemplation (PC, 18.4%), preparation (P, 43.5%), and action/maintenance (A&M, 48.2%). The trend to eat a variety of foods was more distinctive as the students went from the PC to the A&M stage. The stage of change for vegetable intake was closely related with the kimchi-eating pattern of the students. The A&M group ate more vegetables than the PC group because they liked vegetables and/or wanted to prevent disease. The PC group had a lower tendency to follow recommendations for vegetable eating than the P and A&M groups. The PC group also had an incorrect notion that low vegetable consumption over an extended time would not have a big impact on their health. The vegetables of high preference for the elementary school students were potato, sweet potato, lettuce, radish, perilla leaf, cucumber, and cabbage. The vegetables of low preference were spinach, onion, balloon flower, and green pepper. The PC group had lower preferences for most vegetables than the P and A&M groups. Therefore, careful nutrition education is necessary especially for students in the PC group in order to explain the positive effects of vegetable intake and negative effects of an unbalanced diet. It is also necessary to survey students' tastes consistently and to develop recipes that encourage them to consume more vegetables agreeably.
