A nutritional survey was made in 45 healthy Buddhist nuns (age : 20-34 yr) who have been vegetarians for more than 5 years and 20 female college students (aga : 20-22 yr) as a control group in Kyungpook province. Daily calorie intake of the Buddhist nuns and students were 1947 and 1815 kcal, respectively. The ratio of percent calorie of carbohydrate : fat : protein from total calories in the Buddhist nuns was 84 : 11 : 5 and that of the students was 70 : 15 : 15, respecting. The Buddhist nuns had significatly higher carbohydrate intake but markedly lower lipid intake than the students. Daily intakes of thiamin, niacin and ascorbic acid in the Buddhist nuns were higher, but those of iron, calcium and vitamin A were lower than the recommended daily allowances. Compared with the students, the Buddhist nuns had greater intakes of ascorbic acid, vitamin A, thiamin, niacin, and calcium. Anthropometric measurement showed that the Buddhist nuns had significantly higher values than the students in body weight, skinfold thickness, body surface area, and obesity index. There were highly significant correlations between anthropometric measurements and obesity index(0.55< r <0.99). On the other hands, correlation coefficients between nutrients intakes and skinfold thickness and obesity were very low(0.01< r <0.37). The Buddhist nuns and students showed similar normal values of hemoglobin concentration, hematocrit, and blood pressure.

This study was conducted to evaluate the effectiveness and preferences of supplementary drinks for very old subjects who are likely to be malnourished. Twenty- five elderly subjects were divided into two groups. The supplemented group(N=15) received 500mls of nutrient supplement(New Care) two times daily for 4 weeks. This resulted in a significant increase in the total calories, protein, minerals and vitamins. Nutritional status was assessed both anthropometrically and biochemically, before and after the study period. A significant improvement in mid arm circumference, triceps skinfold thickness and serum albumin were observed in the supplemented group but not in the control group. There is a possibility that most of the elderly were in an anemic state at the beginning of the study since their mean hematologic parameters were within the lower normal range while their mean serum osmolarities was slightly higher than normal, . Although mean serum hemoglobin and hematocrit were not increased significantly, th percentage of the recovery rate from anemia in the supplemented group was higher than in the control group. Total lymphocyte count also showed similar tendency. Sensory evaluation of nutritional supplementary drinks were relatively good and the elderly showed great interest in nutrient supplements. This study suggests that a nutritional status of poorly nourished elderly subjects can be improved by providing them with nutritional supplementations.

This study was accomplished to investigate the prevalence of obesity and the factors related to obesity of high school girls in the large cities from May 20 to July 10 1990. In this study, three hundred eighty nine high school girls were chosen from high schools located in Seoul and Inchon. Anthropometry including weight, height, and skinfold thickness (triceps) were measured, and dietary intakes were calculated according to food composition tables. Means of the obesity index, food pattern, nutrients intakes were compared by Pearson's correlation coefficient. Nutrient intakes of the groups categorized by tricep skinfold thickness were compared by means of Duncan's multiple range test. Prevalence of obesity was 16.7%, 3.6%, and 20.8% by criteria of skinflod thickness, BMI, and Rohrer Index, respectively. Most of the subjects had three meals and took snacks two times per day 23.9% of the subjects were taking nutrient supplements of which vitamin supplement was the most popular. Food habit of subjects such as frequency of snack and bedtime meal were positively related to fatness. Nutrient intakes of the obese groups classified by tricep skinfold thickness, tended to consume more calories than another tricep category groups. Therefore, it could be concluded that prevalence of obesity in this subject was higher than the one for the past years, and it was more profound in girls who had a poor food habits and high calorie intakes. Thus, these results suggested that a good food habits and adequate nutrient intakes are essential to prevent the obesity of high school girls.

The purpose of this study was to evaluate weight control program provided by university health care center for female college students. The program was 8-week long and composed of diet, exercise, and behavioral modification. Evaluation was made on the completion of 8-week program and a follow-up survey was done at 3-24 months after the end of program by telephone or bye-mail. Total of 76 women completed the 8-week program and 51 for follow-up survey. On the completion of 8-week program, significant decreases in body weight, BMI, body fat (kg), ％ body fat, and WHR were resulted, however, no change in muscle mass was found. Even the subjects without weight change showed significant reduction in body fat (kg) and ％ body fat. Total food intake was decreased resulting in reduced intakes of most nutrients. Meal distribution of energy was changed; ％energy from snack decreased from 22％ to 14％, and proportion for breakfast increased. Blood values of hemoglobin, hematocrit, total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride were within normal range, and no changes were observed by this program. The follow-up survey revealed that 88.3％ of the subjects continued to lose weight after completion of the program, while only 7.8％ gained weight. And 78.4％ of the subjects considered the program effective. In conclusion, the weight reducing regime with education is effective for long lasting weight control and health conscious behavior for female college student. Since the subjects reduced the size of meal, instead of cutting only calories down, food selection to meet all the nutrient requirements except energy should be emphasized.

The purpose of this study was to investigate the effects of wax gourd on weight, triglyceride, leptin and fat cell size in rats fed a high-fat diet. Male Sprague Dawley rats were fed an experimental diet containing total dietary fat at 40% of calories with wax gourd 0%, 5%, 10% and 15% (w/w) for 4 weeks. Weight gain and triglyceride level fell significantly in the 15% wax gourd group compared to the control group. Epididymal fat pad, abdominal fat and perirenal fat tended to decrease in the 15% wax gourd group. Leptin and free fatty acid level were not significantly different among the groups. Fat cell size significantly decreased in the 10% and 15% wax gourd groups compared to the control group. Weight gain correlated positively with visceral fat masses and the levels of leptin and triglyceride. Fat cell size significantly correlated with visceral fat and leptin level. Therefore, the 15% wax gourd diet substantially reduced weight, triglyceride and fat cell size. (Korean J Nutrition 36(5): 446∼451, 2003)

This study was conducted to evaluate the consumers' preferences and perceptions on the salad and its dressings, via a total of 401 subjects in the Taegu area on the basis of 5-point Likert scale. Anthropometric data included the total subjects consisted of 66 females and 335 males: categorized by age, 20's (103), 30's (135). 40's (83), over 50's (80), The average size of family was 4.2 persons. According to BMI, 64.8% of the subjects belonged to the normal group. The age group that liked salad most was the 20's group, which was also the group that ate salad most frequently. The salad was perceived as food item which is convenient to eat(3.83), healthy(3.63), easy to prepare(3.73) and delicious(3.61) but rarely as a expensive item(2.44). The ingredients, used for salad preparation included fruits and vegetables(3.19) such as tomato and cucumber. Among the salad dressings, the fruit dressing was preferred the most(4.59), while the mayonnaise the least(3.59). The mayonnaise was perceived as an item with highest calories(4.1), and hardly perceived as a luxury item(2.78). The preference for the fruits dressing was highly correlated with the degree of education(p<0.05), age(p<0.001) and BMI(p<0.001). The higher the degree of education, the lower the level of age group, and the lower the BMI, the higher preference for the fruit salad dressing was demonstrated.

Various personalized services are provided based on user context these days, and IoT(Internet of Things) devices provides effective ways to collect user context. For example, user's activity such as walking steps, calories, and sleeping hours can be collected using smart activity tracker. Smart scale can sense change of user's weight or body fat percentage. However, these services are independent to each other and not easy to make them collaborate. Many standard bodies are working on the documents for this issue, but due to diversity of IoT use case scenarios, it seems that multiple IoT technologies co-exist for the time being. This paper propose a framework to collaborate heterogeneous IoT services. The proposed framework provides methods to build application for heterogeneous IoT devices and user context management in more intuitive way using HTTP. To improve compatibility and usability, gathered user contexts are based on MPEG-UD. Implementation of framework and service with real-world devices are also presented.

Purpose: The purpose of this study was to identify the relationship between energy intake and fatigue in cancer patients receiving chemotherapy. Methods: A total of 106 subjects had participated in this study. Data were collected at a university hospital in D city from September 1st to November 10th, 2010. Energy intake including carbohydrates, protein and fat was measured by scale and analyzed using Can Pro 3.0 program. Fatigue level was measured by the Revised Piper Fatigue Scale. Data were analyzed using descriptive analysis, t-test, ANOVA and Pearson correlation coefficient with SPSS/WIN 15.0. Results: The mean calorie intake during chemotherapy was $906.53{\pm}201.28Kcal/day$ which was 45.3% of the recommended daily calorie intake. The mean of protein intake level was $43.62{\pm}11.13g/day$, and it was low compared to the recommended daily protein intake. Calories, carbohydrates, and protein levels on 3rd day after chemotherapy were significantly lower than those of 2nd day after chemotherapy (p<.001). The fatigue level during chemotherapy was $5.77{\pm}0.77$ which was moderate level of fatigue. There was a significant negative interrelation between energy intake and fatigue. Conclusion: Theses results suggested that nursing approaches to encourage dietary intake may be helpful to reduce fatigue for cancer patients receiving chemotherapy.

The nutritional status and chronic disease occurrence of the elderly living in local areas is affected by certain factors, including low energy intakes, low food diversity, poor nutritional quality and living alone. Moreover, elderly people who live alone may have low incomes and be socially isolated. Thus, we have provided them adjustable and balanced menus using standard recipes. In this study, we investigated aspects of nutritional status and living conditions in the elderly status, in relation to food, activities of daily living(ADL), nutrition risk index, average intake of calories and nutrients, the mini dietary assessment index score, depression score, menu satisfaction, menu demand, satisfaction with menu offerings. The result indicated significant nutritional improvements by providing menus to the elders and suggest that by providing adjustable and balanced menus using standard recipes, the nutritional status of isolated elders can be changed and improved.
