Korea's aging population has been remarkably increased. They want to have not only extension of life expectancy but also improving quality of life. To maintain the quality of life, it is essential to have good nutrition. However, nutritional status of elderly in Korea has problems qualitatively and quantitatively. Risk factors for poor nutrition are advanced age, woman, living alone and low economic status. Another risk factor in rural area is season because seasonal changes can affect food intake of elderly. Thus this study surveyed the health status and dietary intakes of elderly by season in rural area. In this study, the elderly were grouped as group 1 {elderly who have one risk factor for chronic diseases (obesity, hypertension, dyslipidemia, diabetes)} and group 2 (elderly who have more than 2 risk factors). Can-Pro 3.0 was used for dietary data analysis and SPSS 12.0 program was used for statistical analysis. Obesity had the highest percentage 62%, followed by hypertension 59.5%, dyslipidemia 21.5% and diabetes 11.6%. Obesity, hypertension, and dyslipidemia were high in winter and WHR, diabetes and anemia were high in summer. Mean intakes of energy and nutrients were less than RI. Nutrients which were changed most by season were vitamin A and Vitamin C. Intakes of calcium and folic acid were less than recommended in summer. The ratio of CPF for carbohydrate was higher and fat was lower than recommended. In conclusion, the nutrient intake of Group 2 was better in quality but Group 1 was better in quantity. Nutrient intakes were poor in summer. In rural area, more careful nutritional assesment and management are needed for aged population, especially in summer.

Evaluation of nutritional status of the elderly imposes different problem from the other age groups. It is essential to use right instrument to assess food consumption. In Korea, the food frequency questionnaire has not been applied widely to elderly people. The purpose of this study is to assess the possibility of employing a semi-quantitative food frequency questionnaire(FFQ) for the Korean elderly to estimate nutrient and/or food intakes. In this study the FFQ for the elderly was developed and validated. The subjects were 144 free-living old women aged from 65 to 90. The FFQ was designed with 4 items for cereals and 86 items for other foods and with frequency of 12 intervals. Three portion sizes were given to select : 1/2 of standard amount, standard amount, and 11/2 of standard amount. ach subject was interviewed with newly developed FFQ form and same subjects were also involved to complete 3-day diet record. Nutrient intake was calculated using software program developed by our group. The nutrient intakes by the FFQ was validated by comparing the results with 3-day diet record. The FFQ estimated significantly higher mean intakes of energy, carbohydrate, protein, fats and vitamin C than did the diet reconrds(p<0.05). Pearson's correlation coefficients between two methods ranged from 0.21 for vitamin Q to 0.69 for alcohol(mean r=0.53). From 32% to 42% of the subjects were classified in the same quintile of nutrient intake by two methods, and 63% to 84% were classified in the same or adjacent quintile. On average, only 4% of the subjects were misclassified into extreme quitiles. The results indicate that the FFQ developed for the elderly in this study is useful for classifying individuals by rank and identifying groups at extremes of nutrient intakes.

The purpose of this study was to identify dietitians' perception and purchasing pattern of fruits in elementary school lunch program. This study was conducted using mail survey from September 15 to October 30, 2006. Survey questionnaire was developed based on in-depth interview with three school food service dietitians. A total of 100 school food service dietitians in Seoul were participated. Based on the frequency analysis results, over half of respondents(69%) provides fruits every week, and 23% of respondents provides them twice a week. Strawberry, watermelon, apple, and mandarin were identified as the most frequently served fruits in Spring, Summer, Fall, and Winter, respectively. Sixty two percent of respondents indicated they offered imported fruits, such as banana and pineapple, less than 10% of total fruits. Ninety three percent of respondents selected private contract when they purchase fruits, and forty four percent of dietitians decided fruits purchasing procedure by themselves. Respondents addressed "Apples and Pears were appropriate for a dessert." and "Apples and Pears supply nutrition such as calorie and vitamin." as the advantages of offering apples and pears in school lunch menu. They also indicated difficulty in preparation work and many leftovers as the disadvantages of offering apples and pears. When purchasing apples and pears, dietitians considered taste as the first criteria and price as the second. Respondents perceived that elementary school students preferred apples and pears in a neutral level. Respondents also had higher preference for an-sim apples which can be eaten without peeling for school lunch menu and higher intentions to provide in school lunch menu. The survey results also found that respondents' intention to offer apples in school lunch menu was higher than intentions to offer pears. The implications to increase the chance of fruits offering in school lunch menu were discussed.

The purpose of this research are to forecast the demand and supply of milk in Korea, and to obtain information for attitudes affecting milk consumption, which is necessary to make a plan for increasing milk consumption in Korea. The estimation of the milk demand and production was made by the multiplicative decomposition method and the statistical function. Data on consumer were collected from 737 students who were attending primary school, middle school and university in Daejeon during the period of July 11 to July 21, 1988. The results obtained are as follows; 1. The prediction results showed that the production for milk will over supply 21,900 tons in 1,990, 70,800 tons in 1,995 by the multiplicative decomposition method and 45,400 tons in 1990, -51,500 tons in 1995 by the statistical function. 2. It was found that almost all the students awared milk as essential food-stuff of common food stuff for the Koreans. 3. Quite a few students were apt to believe that milk processors added water into fluid milk. 4. Most students showed obtaining information about the nutritional value of milk by school education and advertising of TV, Radio, and Printed media. 5. However, it was found that the advertising by TV, Radio, and Printed media did hardly give to consumers influences on the choice of a particular milk brand. Accordingly, the conclusions are as follows; 1. Need to provide consumers with well planned education programs on the nutritional value of milk. 2. Heavy brand advertising for fluid milk may mislead the understanding of consumer, since city milk is not much differentiated in Korea. Therefore the milk processors should put more efforts in generic milk promotion by reducing brand advertizement. 3. The milk processors should provide major portion of financing for generic milk promotion program.

Two experiments were conducted to evaluate the nutritional value of common fodder tree leaves with goats fed at 50% of total ration. In experiment 1, leaves from six fodder tree species i.e., Ailanthus aitissima, Elaeagnus angustifolic, Morus alba (Mulberry), Populus spp, Robina pseudoacacia and Salix babylonia were harvested in spring and winter from northern areas of Pakistan. Chemical composition and apparent in situ dry matter digestibility (DMD) of fodder tree leaves were measured. Results showed that crude protein (CP) values were higher (p<0.05) in all the species during spring compared to winter (17.9% vs 12.0%). The concentration of NDF in Elaeagnus and Robinia was higher in spring, whereas no seasonal difference was found in other species. In situ DMD was higher (p<0.05) in Ailanthus and Populus at spring while it was higher (p<0.05) in Elaeagnus, Mulberry and Robinia at winter. There was no (p<0.05) seasonal effect on in situ DMD of Salix. In experiment II, four iso-nitrogenous and iso-caloric rations viz., A, B, C and D were prepared containing 50% (winter harvested) sun dried leaves of Salix, Robinia, Mulberry and Elaeagnus, respectively and 50% concentrate. Dry matter and crude protein intakes were higher (p<0.05) given ration A (Salix) whereas DM and CP digestibility was lowest (p<0.05) given ration B. Nitrogen retention was higher (p<0.05) given ration A. Goats fed on fodder tree leaves and concentrate showed moderate intake and digestibility.

Health could be maintained and promoted by pursuing an active healthy lifestyle. Life-style include health habits and behavior pattern such as exercise, diatry change, weight control, stress management et al. The objectives of this studies are (1) to analyze recognition and practice of lifestyle between nurses and non-nurses, (2) to analyze health status of clients which presented healthy lifestyle, (3) to analyze factors that affected healthy lifestyle. The lifestyle assessment questionnaire is divided into ten sections: competence in selfcare, nutritional practices, physical activity, sleep patterns, stress management, self-actualization, sense of purpose, relation with others, environmental control, and use of health care system. The major results are as follows : (1) The level of recognition and practice of lifestyle was not high. Nurses showed more higher score than non nurses in lifestyle area such as competence in selfcare, stress management, environmental control, and use of health care system. (2) Good health status and lifestyle presented positive relation. (3) In mutiple classifiction analysis, competence in selfcare, nutritional practices, physical activity, sleep patterns, stress management, environmental control, and use of health care system had significant relation to independent variables. (4) Change of concept for healthy lifestyle after this survey was higher in nurses group and the most concern area was stress management. To sum up, lifestyle pattern of nurses as health professional was not desirably high. Therefore nurses ownself should effort to practice healthy lifestyle prior to others, and then educate importance of lifestyle for health promotion and disease prevention. In conclusion, it will be useful to consider significant lifestyle factors that was be identified in this study to develop health promotion program.

Tea derived from the leaves and buds of Camellia sinensis (Theaceae) is consumed worldwide. Green tea contains various components with specific health-promoting effects, and is believed to exert protective effects against diseases including cancer, diabetes and hepatitis, as well as obesity. Of the various tea components, the polyphenol catechins have been the subject of extensive investigation and among the catechins, (-)-epigallocatechin gallate has the strongest bioactivity in most cases. Our research group has postulated that hepatocyte nuclear factor-$4{\alpha}$, sterol regulatory element-binding proteins, and tumor necrosis factor-${\alpha}$ are targets of green tea constituents including (-)-epigallocatechin gallate for their anti-diabetes, anti-obesity, and anti-hepatitis effects, respectively. Published papers were reviewed to determine whether the observed changes in these factors can be correlated with anti-cancer effects of green tea. Two major action mechanisms of (-)-epigallocatechin gallate have been proposed; one associated with its anti-oxidative properties and the other with its pro-oxidative activity. When reactive oxygen species are assumed to be involved, our findings that (-)-epigallocatechin gallate downregulated hepatocyte nuclear factor-$4{\alpha}$, sterol regulatory element-binding proteins, and tumor necrosis factor-${\alpha}$ may explain the anti-cancer effect of green tea as well. However, further studies are required to elucidate which determinant directs (-)-epigallocatechin gallate action as an anti-oxidant or a pro-oxidant for favorable activity.

This study was conducted to prepare basic materials and offer advice regarding dietary habits to prevent and cure childhood obesity by comparing and analyzing dietary habit, nutritional status, blood factors, and mineral contents of hair. All subjects were stratified by their weight-length index (WLI). According to the standard WLI values, 64.9% of children were within the normal value, 13.5% of children were underweight, and 21.6% of children were overweight and obese (WLI ${\geq}$ 110%). Overall, the score assessed dietary habit for all children was $21.32{\pm}2.55$ point (921 subjects), with 5.1% of children having excellent dietary habits and 3.1% having poor dietary habits. Additionally, 37.9% of underweight children, 37.6% of normal weight children, and 43.2% of overweight and obese children consumed higher amounts of protein than underweight children did (meat, fish, eggs, and soy products) (P < 0.05). Overweight and obese children consumed more fried foods than underweight or normal weight children (P < 0.05). Moreover, 38.0% of the children had hemoglobin levels of 12 g/dl, while 7.6% were anemic (11.1 g/dl). When a hematocrit level of 33% was taken as the standard, 11.0% of children were anemic. The plasma transferrin content was $263.76{\pm}54.52$ mg/dl in overweight and obese children. The mean values of Fe, Cu, Ca, Cr, Mn, Se, Na, K, Li, V, Co, and Mo were within the reference values, but the Zn concentrations of underweight, normal weight, and overweight and obese children were $67.97{\pm}28.51$ ppm, $70.09{\pm}30.81$ ppm, and $73.99{\pm}30.36$ ppm, respectively. The Zn concentration of overweight and obese children ($73.99{\pm}30.36$ ppm) was lower than that of the standard value (180~220 ppm). Therefore, a nutritional education program and new guidance for dietary pattern should be developed to reduce the number of underweight and overweight and obese children.

According to the dietary surveys and national food balance sheets, the dietary state of person living in Korea is ingesting a high level of grain and vegetable diet and very low animal sources. The daily calory intake is about 2,300-2,600 Cal. per head in which a total protein intake is 69-86 gm respectively. These data indicate no shortage of calory and total protein intake. However, the intake of animal protein is only 4-11 gm and the fat is 8-18 gm, both of which are far below the requirment. The low fat intake brings about a low level of fat soluble vitamins, and that V-A intake is as short as the half amount of the allowance. Riboflavine is also about a half of dietary requirment. Both thiamin and ascorbic acid intake are sufficient. The calcium intake is 0.26-0.5 gm per day which is inadequate. In fact, biochemical findings through field survey show; serum protein 6.7 gm, hemoglobin 13.1 gm and hematocrite 41.5% all of which are lower than the Kwon's report. The serum V-A and uunrinary riboflavin value are also lower than the Williams'es report. Clinically, inflamation of the eyes, cheilosis, pathological signs of tangue, xerosis of the hand and arm, or the like are frequently seen. On the other hand, there is no suitable diet available for the weaning infant and delayed weaning is a common practice. A school lunch program is still in an early stage of development. Another example can be cited that the Korean infant grows faster than the Japanese until one year of age, and no difference is noted between the Korean and the American infants up to six monthes of age, thereafter the former lags in the growth rate. This might be mainly due to the nutritional reasons as mentioned above, and in part due to the high inidence of intestinal parasitism and others.

Nutritional evaluation of the proposed supplementary foods (high nutrition-low cost foods) for children were conducted for the ‘Wonseong County Comprehensive Nutrition Program’ in Korea. Proximate composition, mineral, vitamin and amino acid composition were determined and also protein efficiency ratio(PER) was evaluated for the propsed formulas which were recommended as CSS (corn-soybean-sesame blend)-3, CSS-4 and BSS (barley-soybean-sesame blend)-4 in previous study. Protein and caloric contents of the formulas were around 18% and 400 Kcal/100 g respectively, and they have reasonable contents of mineral and vitamin. Amino acid score (83-89) and PER (2.33-2.36) of the proposed formulas were considered to be in adequate range of protein quality for feeding the target group in Wonseong County area.
