The purpose of this study was to investigate the effects of the nutrition therapy and drug(simvastatin) treatment on the levels of blood lipids for the hyperlipidemic patients according to genetic polymorphism of apo CIII. Subjects of the study consisted of 43(male: 9, female: 34 )hyperlipidemic patients registered to Kyung Hee Medical Center, Intakes of nutrients for the subjects were determined by 24-hr recall method through a personal interviews. The subjects were instructed to take the hypolipidemic and hypocholesterolemic diets. Compliance was monitored through food records, personal interview, and body-weight measurements. The patients changed their basal diet containing 40. 1g fat(182.7mg cholesterol./day) to a diet containing 30.7g fat(139.2mg cholesterol/day) after 12 weeks of nutrition therapy. The distribution of genotypes for apo CIII by Msp I was 32.5% of TT, 50.0% of TC, and 17.5% of CC. aT the beginning of the study, the level of blood triglyceride was the highest for patients with TT and TC. Following the nutrition therapy, patients with CC exhibited the largest drop of blood triglyceride. Following simvastatin treatment with nutrition therapy, blood LDL-cholesterol decreased in most of the patiens with TT. Meanwhile the distribution of genotypes for apo CII by the Fok I was 10.0% of TT, 47.5% of TC, and 42.5% of CC. The level of blood triglyceride was the highest for patients with CC. Following the nutrition therapy, patients with TC exhibited a significant drop for the blood triglyceride. Following simvastatin treatment with nutrition therapy the level of blood LDL-cholesterol decreased in most of the patients with CC. We concluded that dietary habits and food have been changed by nutrition therapy. And blood lipid levels have been decreased by the restriction of intakes of energy, fat and cholesterol. There was variation in the levels of blood lipids according to apo CII polymorphisms. The level of blood lipids responded to nutrition therapy and drug treatment in different was according to genetic polymorphisms. Accordingly, the choice of individualized therapy based on the patient\\`s genetic polymorphism is very important for effective therapy(Korean J Nutrition 33(8) : 813-823, 2000)

The purpose of this study is to provide the information of the aged olds for which basic data are almost no available. The subjects were divided on the base of age 75. The elderly under 75 were named 'the young olds' and over 75 were 'the aged olds'. The aim of this research is to promote health and to improve nutrition, and the survey was made for health promotion behaviors, habits against health risk, dietary management status and diet intake. And it was conducted by 24 hr-recall method and analyzed by nutrients intake. 242 subjects were collected in 12 cities or counties in Gyeonggi Province and 20 elderly people (10 male and 10 female) were selected out of 1 village in each district. Questionnaire about health behavior and dietary management was carried out by interview method through regional home extension workers. Statistical analyses were made by SAS (version 8.1) and Chi-square tests and General Linear Models were used. Out of the subjects the aged olds over 75 was 31.9%, elementary school educated (93.5%), with spouse (40.3%), with adult children(28.6%), monthly living cost of 500-1,000 thousand won(40.3%). Mean age was 78.82 years compared with 69.75 years of the young olds. 46.8% of the aged olds used monthly pocket money over 1000 won and it was lower than 63.3% of the young olds. Only half of the aged olds had regular exercise of walking (77.8%) or with athletic equipment (17.8%). However, the young olds did more frequent walking (82.1 %) and less exercise with athletic equipment (4.8 %), which was significantly different. Kinds of disease were different with the young or the aged olds, as more proportion of cardiovascular disease(37.9%) for the young olds and joint lumbago neuralgia(41.6%) for the aged olds. Dietary management was good (3 meals per day: 93.4%, fixed mealtime: 72.4%, and regular amount: 79.9%). But there was significant difference in side dish varieties and kinds of snacks; for the aged olds only 8% had over 5 sorts (compared with 18.8% of the young olds) and the kinds of snacks were cookie, candy, juice, carbonated beverage for the aged olds (compared with noodle, milk, soybean-milk for young olds). The ratio of nutrients intake (energy, riboflavin and niacin) with RDA was significantly higher for the aged olds than that of the young olds. The surveyed subjects had no difficulties in Activities of Daily Living (ADL), but some of the aged olds had difficulties in Instrumental Activities of Daily Living (IADL) like housekeeping, using transportation, going shopping and making phone calls. These results suggest that low quality of life is linked with low economic status of the rural elderly and congregate meal at village hall would be required because of the lack of side dishes variety for the aged olds. And nutrition education program about good snacks and exercise practice would be needed for the aged olds. By operating nutrition education program the aged olds would enjoy better quality life maintaining or ameliorating IADL abilities.

This study was conducted to investigate the effect of a 3 week low calorie diet (LCD) and a 9 week of behavior modification (BM) program on the weight loss, mineral and vitamin status in 22 obese women. The subject were healthy, obese (PIBW> $120\%$) women aged 20 - 50 Yr and not taking any medications known to influence body composition, mineral or vitamin metabolism During the LCD program, subjects were provided commercial liquid formulas with 125 kcal per pack and were instructed to have a formula for replacement of one meal and at least one regular meal per day within the range of daily 800 - 1200 kcal intake. During the BM program the subjects weekly attended the group nutrition counseling session to encourage themselves to modify their eating behavior and spontaneously restrict their energy intakes. The BM program focused on stimulus control, control of portion sizes and modification of binge eating and other adverse habits. The initial mean energy intake of subjects was 2016.9 $\pm$ 129.8 kcal ($100.8\%$ of RDA) and dropped to 1276.5 $\pm$ 435.7 kcal at the end of a 3 week of LCD program and elevated to 1762 $\pm$ 329.3 kcal at the end of a 9 week of BM program. Carbohydrate, protein and fat intakes were significantly decreased at the end of the LCD but carbohydrate was the only macro nutrient that showed significant decrease (p < 0.05) at the end of the BM program compared to baseline. Calcium and iron intakes decreased significantly (p < 0.01, respectively) with no significant changes in other micronutrients at the end of the LCD. The mean weight of the subjects decreased from 73.8 $\pm$ 8.0 kg to 69.2 $\pm$ 7.7 kg with LCD and ended up with 67.7 $\pm$ 7.1 kg after 9 weeks of BM. The 3 weeks of LCD reduced most of the anthropometric indices such as BMI, PIBW, fat weight, wast-to-hip ratio and subscapular and suprailiac skinfold thickness. The 9 weeks of behavior modification showed slight change or maintenance of each anthropometric measurements. Weight loss and decreased WHR with the diet program induced significantly decreased systolic blood pressure. SGOT, SGPT and serum insulin levels with improved serum lipid profiles. Biochemical parameters related to iron status such as hemoglobin, hematocrit were significantly decreased (p < 0.01) at the end of the LCD. But their mean values were within normal range. The mean serum 25 (OH) vitamin $D_3$ level significantly increased after whole diet program. Serum folate level significantly decreased after 12 weeks of diet program. In conclusion 3 weeks of LCD brought 4.6 kg reduction in body weight without risk of iron, zinc or vitamin D deficiency and 9 weeks of the BM was effective to maintain nutritional status with slightly more weight reduction (1.5 kg). However calcium intake and serum folate should be monitored during the LCD and BM because of increased risk of deficiencies.

Jeon refers to a type of Korean cuisine used as a side dish, made with various ingredients such as meat, vegetables, or fish, mixed with flour batter and coated with egg batter and then pan-fried on both sides with oil so that heat spreads through them well. The aim of this study was to provide a cornerstone of further research on Korean dietary life, by reviewing types, recipes and names of Jeon recorded in ancient cookbooks (Korean literatures) and by analyzing changes in recipes to make Jeon, which our ancestors used wisely as one type of side dish. Considering developments and changes recorded in old documents, the Jeon recipe appeared relatively later than the recipes for grilling, steaming et al, which had been developed much earlier, and it had not been recorded until the 1600s. Changes of Jeon recipes by time period are as follows. In the 1600s, there were three recipes: frying only with grain batter after preparation of ingredients, frying right after preparation of ingredients, and putting ingredients on already fried watery batter. These three recipes were still used in the 1700s, in addition to a new recipe, in which ingredients were oil-fried to be skewered. Today's recipe in which prepared ingredients are fried after getting coated with flour and egg only appeared in 1800s. This has been the main recipe for Jeon ever since. In that time period, there was more variety of recipes and ingredients than before. For instance, Jeon was used for soup or steamed dishes instead of being served as a dish itself. Buchimgae with mixed ingredients was also considered Jeon. In the 1900s, there appeared more names for Jeon as more sorts of ingredients got used, even though there were no new recipes for Jeon. The above-mentioned historical records show that traditional recipes for Jeon have been applied to various dishes, using diverse ingredients, and it might be a smart solution to today's problematic dietary habits involving excessive intake of nutrients, in that it provides a healthy way to add fat. In the same sense, the recipe for Jeon can play an active role in internationalization of Korean foods, in which healthiness is a main feature. According to ancient documents, the recipes for Jeon were used even for meals that were not side dishes, such as Jun-Gwa (Jung-Gwa), Jun-Yak and fried rice-cake. Also, there were dishes using the same recipes even without carrying the name of Jeon, like Buchim or Jijim. This might be worthy of further examination in culinary science.

Atopic dennatitis (AD) is one of the major public health problem. It has been reported that the prevalence of AD in children and adults are 10-20% and 1-3%, respectively. Westernization of food habits, urbanization, and environmental pollution are contributing factors toward the recent rise in prevalence. Excessive dietary restriction leads to chronic malnutrition in atopic dermatitis patients. The purpose of this study was to investigate the effects of medical nutrition therapy (MNT) on quality of diet and blood immune parameters in atopic dermatitis patients. The 19 atopic dermatitis patients (7 men and 12 women) admitted to K University Medical Center were studied. During the 12 weeks of intervention, the subjects were given MNT by a dietitian for 30-45 minutes every other week. MNT was comprised with general dietary therapy, intake of balanced meals, emphasis on n-3 fatty acid contents in foods, and food allergies. Anthropometric and dietary assessment and blood analysis were taken at baseline and after 12 weeks of MNT. After 12 weeks of MNT, the subjects' dietary qualities, including dietary diversity score (DDS), meal balance score (MBS) and dietary variety score (DVS) were significantly increased (p < 0.05). According to significantly increased intake of EPA and DHA, dietary n-6/n-3 fatty acid ratio decreased to the recommended level for the atopic dermatitis patients (p < 0.05). These changes of dietary fatty acid consumption were reflected erythrocyte fatty acid composition. After 12 weeks of MNT, serum levels of IgE and IL-4 levels were significantly decreased, however, the levers of INF-$\{gamma}$, WBC, lymphocyte and TLC were not changed. As a conclusion, the individualized MNT improved the quality of diet in atopic dermatitis patients thereby influenced RBC fatty acid composition and IgE and IL-4 levels.

Changes in food preferences and dietary habits of Korean prone to decrease consumption of the traditional energy source, rice. The exceeding condition of rice production in Korea is now not only impacting on the profit structure of farmers but also threatening food security. Although there have been several efforts to increase rice consumption rate, by developing various processed foods using rice flour, grain hardness of rice has been the most significant limiting factor. In this study, we addressed the suitability of the Namil(SA)-flo1, a mutant rice line has floury endosperm, in terms of producing rice flour by using dry-milling method, which is lower cost and more eco-friendly than other available methods such as wet-milling. Rice flour of the Namil(SA)-flo1 exhibited superior physico-chemical characteristics to any other check varieties including the wild type, Namil, in terms of distribution of granule sizes and content of damaged starch.

The prevalence rate of metabolic syndrome has increased rapidly among the middle-aged and seems to be affected by socioeconomic factors, lifestyles and dietary habits. This research tries to find out the difference in dietary intake between middle-aged with and without metabolic syndrome. Using Korean National Health and Nutrition Survey (KNHANES) in 2005 and 2007, this study investigated 2,382 people (normal: 1,575, disease: 807) in 2005 and 1152 people (normal: 747, disease: 405) in 2007 (between the age of 40 and 64). Analysis was performed to discover the difference in nutrient intakes between people with and without metabolic syndrome. Also differences among people with various socioeconomic factors (such as age, education level, and income level), which can affect nutrient intake, were analyzed. In the nutrient intake people with metabolic syndrome has lower intake in most of nutrients than those of normal group, except carbohydrate. In 2007, normal group had higher intake in most nutrients, except for carbohydrate, sodium, potassium and vitamin A. Carbohydrate: protein: fat (C: P: F) ratio for metabolic syndrome group showed higher rate for carbohydrate, than normal group, in 2005, and 2007. Overall, the higher age and income level, the more carbohydrate intake rate is increase in metabolic syndrome group. The Quality of each nutrient intake was assessed using NAR (Nutrient adequacy ratio) and MAR (Mean adequacy ratio). According to the MAR, there was significant difference in 2005, 0.83 for normal group and 0.81 for metabolic syndrome group but there wasn't any in 2007 (0.81 for normal group, 0.82 for metabolic syndrome group). By NAR, in 2005, all nutrient except phosphorus, iron, vitamin A for Normal group higher then those of metabolic syndrome group (p < 0.05). In 2007 intake of metabolic syndrome group were higher then those normal group in most of nutrient by NAR. For age, education and income, MAR for normal group is higher then that of metabolic syndrome. In conclusion, Quality of nutrient intake in normal group is better then in metabolic syndrome group. Therefore, it is necessary to monitor dietary of intake people with metabolic syndrome, and necessary measures should be taken.

To get a basic information for improving Korean's pattern of comsuming red pepper and the possibility of its industrial production, consumer's ways of red pepper processing and his present dietary habits were surveyed and the results are follows; (1) Korean's daily consumption of red pepper was on the average 9.2 g on the basis of the whole dried red pepper. (2) The tendency of evading the home drying method was increased; 72.22% in urban community and 50.4% in rural community purchased the dried red pepper in the lump yearly. The household purchasing the fresh red pepper and using the home drying was 27.8% in urban community and 49.6% in rural community, so one third of urban household was still using the home drying method. The case of dependence on tine drying factory was no more than 2.6%. (3) Drying method was mainly sun drying which done on the poor circumstance like as the street side without the proper equipment of drying. Home process of red pepper by housewife was 70.8%, and the old, housekeeper were only 7.3% respectively. (4) The hygienic sense in the drying was rare; 68.8% was not washed and 51.9% of decayed red pepper was eaten. (5) Koreans prefered the strong pungency, deep red color and fine powder form. (6) While the 45.5% of seed was collected by second hand dealer and made use of as resources of edible oil, it was not used effectively due to complexity of its collection system. (7) While 40.1% desired the improvement of red pepper dietary life, 41.1% distrusted the present commercial red pepper powder on the market. From the results above, we conclude the fact many households have still hygienically poor red pepper processed at home, in spite of the red pepper is one of the most important spices in Korea. Considering the growing urban population, reduction of unemployed labor due to the increasing nuclear family and hygienic problems caused by the serious pollution, the improvement of red pepper processing method is urgently required. And it is believed that red pepper has a good prospect to be processed on the industrial scale in Korea.

1. This report is on the outcome of observation made up the breeding process of Narcissus flycatcher, Muscicapa narcissina zanthopygia, using 15 ness-boxes at Seoul and Kwang Nung Experimental forest in 1964, and the relevant feeding habit was studied by the collar method of wrapping the necks of thenestlings for 50-60 minutes or more in some cases from 1963 to 1964. 2. The Narcissus flycatcheris a common summer resident throughout Korea arriving at the end of April. The earliest data of arrival of this species in Seoul, is April 26, 1964. They migrate southward from the later part of September to early part of October. 3. In a week after their arrival , they start to build nest after a brief courtship. Male and female prepare their nest ina nestboxes in 4 or 5 days. Nests are usually found in the moss, which provide definite frame-work. The inner side of the nest is usually composed of roots of Gramineae or leaves of pine, oak or other broad leave tree. 4. The laying period is generally from the later part of April to the middle of June : and the number of eggs laid is from 3 to 8 , therefore 5 in average : eggs are pink with traces of milky yellow blending of light auburn and orange red spots and chicken-egg-like in shape. 5.The incubation takes place for 7-12 days from the middle part of May to the middle of June, in the order of male and female . The hatching rate tends to increase in proportion to clutch size. 6. The feeding period usually lasts 15 days in average from the early part of June to the middle of July and the feeding urge tends to increase in proportion to brood size. 7. The animals invading into their nest-boxes are red ants, chipmunks, bees , barkbeetles and philippine red-tailed shirkes, etc. 8. On the basis of analysis covering 714 birds in 31 nests, the food they consumed during the nesting period of nestlings were mostly of animal matters composing of : insect larvae form-39. 88% insect adult form 36.26%, insect pupae-0.19%, spider-17.75% and other animal matters 5.92% , Besides a small amount of plant pieces were found . As to the insect larvae, Lepidoptera was the largest in the content followed by Hymenoptera , Orthoptera and Coleoptera. As to the insect adult, Diptera was the largest in the content followed by Coleoptera, and Hymenoptera. In view of forest protection, noxious insect was of 69.38%, useful insect 4.39%, and spider 17.75%. 9. The rich assortment of its food, the ability of acquiring various insect (adults as well as larvae), its destruction of great numbers of harmful insects , and its quick assimilation artificial nesting with the nest-boxes of 2.5-3cm entrance hole employed, allow us to conclude that the flycatcher may be successfully employed in the elimination of fores pests. The above results are only that part obtained near Seoul in the middle of Korea, however, if we would extend the scheme to other broad areas using similar techniques, the nest-boxes could not only be well used by the birds, but also it would help to prevent the increase of harmful. insects.

The current study was conducted to identify technology for the production of high quality pork, based on the meat consumption habits of consumers. Macsumsuk, a type of kaolinite (a clay mineral), and/or a mixture of herbs (Mori Folium, Sophorae Radix, Glycyrrhizae Radix, Citri Leiocarpae Exocarpium, and Pogostemi Herba) were added to the diets of fattening pigs. Sixty barrow pigs (4 kinds of treatment ${\times}5$ pigs/treatment ${\times}3$ replicates) were randomly assigned to either the Control (no additives), T1 (3% Macsumsuk), T2 (3% Herb mixtures), or T3 (3% Macsumsuk + 3% Herb mixtures) groups, and were fed the diets for 60 d. Dressed weights were in the order of T1 ($93.40{\pm}4.68kg$) > T2 ($91.40{\pm}6.52kg$) > Control ($88.80{\pm}1.57kg$) > T3 ($86.80{\pm}2.01kg$). Back-fat thickness of the Control animals ($23.2{\pm}1.03mm$) was significantly greater than that of the various treatment groups (p<0.01). Numeric values representing the carcass yield and quality grade were higher for all the treated groups than the Control group, thought the difference was not statistically significant. Crude fat content was significantly higher in the Control group ($2.23{\pm}0.34%$) than in the treated groups (p<0.05). The addition of both Macsumsuk and herb mixtures into the diets of the pigs significantly reduced cooking loss of the pork compared to the Control (p<0.05). No statistically significant changes were observed in the shear force (average $5.87{\pm}0.54kg/cm^2$), water holding capacity (average $54.59{\pm}3.16%$), or CIE values of the pork, whereas cholesterol levels significantly decreased (p<0.01) in those fed Macsumsuk and/or the herb mixtures. No significant changes in fatty acid composition, total saturated fatty acid (SFA), total unsaturated fatty acid (UFA), or UFA/SFA ratios were observed by any of the treatments. In conclusion, the results obtained from this study suggest that the addition of Macsumsuk and/or herb mixtures into the diets of growing and fattening pigs improves the pork quality by reducing cooking loss, decreasing cholesterol content, and enhancing sensory characteristics.
