The calcium intake of elementary school students residing in Gyeongsangbukdo province from their school foodservice and milk program was evaluated. A total of 252 subjects (50.4% boys and 49.6% girls) were examined. A significant percentage of the total subjects (32.9%) reported skipping breakfast once or more per week, with the major reasons for skipping breakfast being a lack of time and appetite. A majority of the to-tal subjects (78.2%) participated in the school milk program. The type of milk consumed by the subjects was mainly white milk, with a milk intake mostly between one and two cups. Participants in the school milk program consumed over the recommended nutrient intake (RNI) of calcium, but non-participants consumed only 48.1% of the RNI (P<0.001). The calcium intake rate according to food cooking methods, from highest to lowest was in the order bap, twigim, jeon, jjim, and gui. Although the food intake rate of guk was low, the calcium intake rate by RNI was the highest for guk. On the other hand, the food intake rate of bap and kimchi was high, but their calcium intake rate by RNI was relatively low. These results show that non-participants in the school milk program are significantly deficient in calcium. Therefore, to improve the calcium nutrition for children, school lunch menus containing high calcium need to be developed and children should be encouraged to enter a school milk program.

My prior questionnaire has applied to 12 male and 29 female adults over 30-69 years old suffering from lumbago fer 6 months at least or having diagnosis of lumbago. I had the following conclusions from physical characteristics and cardiopulmonary capacity of lumbago Patients caused by obesity 1) The rate of lipids in the body was rotated to the maximum heart rate in the male group of lumbago patients (P<0.01). 2) The rate of lipids in the body was related to the maximum intake of oxygen(O2) in the male group of lumbago patients(P<0.01). 3) The maximum heart rae was related to the maximum intake of oxygen in the male group of lumbago patients(P<0.01). 4) The rate of lipids in the body was related to the maximum intake of oxygen in the female group of lumbago patients(P<0.05). 5) The rate of lipids in the body showed no relation to the maximum heart rate in the female group of lumbago patients(P>0.05). 6) The maximum heart rate was related to the maximum intake of oxygen in the female group of lumbago patients(P<0.01). 7) The cardiovascular system showed no relation te the function of the lungs in the male and female groups of lumbago patients(P>0.05) 8) The lung capacity per second of lumbago patients(FEV $1.0\%$) measured less than normal adults. 9) The maximum intake of oxygen(V02max) and heart rate was less than normal adults. Thus I summarized the conclusion so follows: the cardiovascular system of lumbago patients showed no relation to their pulmonary function, and the rate of lipids in the body Showed a correlation with the maximum intake of oxygen but the rate of lipids in the body showed no relation to their pulmonary function.

Under a typical Mediterranean environment in southern Australia, the evaporation rate increases significantly in hot summers, resulting in highly saline drinking water for grazing animals. Also in the cropping areas, dryland salinity is a problem. Grazing animals under these environments can ingest excessive amount of salt from feed, drinking water and soil, which can lead to a reduction in growth rate. To understand the impact of high salt intake on grazing deer, two experiments were conducted to assess the effect of salt levels in drinking water on feed intake and growth rate of red and fallow weaner deer. The results revealed that fallow deer did not show any abnormal behaviour or sickness when salt level in drinking water was increased from 0% to 2.5%. Feed intake was not affected until the salt content in water exceeded 1.5%. Body weight gain was not affected by 1.2% salt in drinking water, but was reduced as salt content in water increased. Compared with deer on fresh water, the feed intake of red deer on saline water was 11-13% lower when salt level in drinking water was 0.4-0.8%. An increase in salt level in water up to 1% resulted in about a 30% reduction in feed intake (p<0.01). Body weight gain was significantly (p=0.004) reduced when salt level reached 1.2%. The deer on 1% salt tended to have a higher (p=0.052) osmotic pressure in serum. The concentration of P, K, Mg and S in serum was affected when salt level in water was over 1.0%. The results suggested that the salt level in drinking water should be lower than 1.2% for fallow weaner deer and 0.8% for red weaner deer to avoid any reduction in feed intake. Deer farmers need to regularly test the salt levels in drinking water on their farms to ensure that the salt intake of grazing deer is not over the levels that deer can tolerate.

The purpose of this study was to investigate eating behavior, nutritional status and health condition of obese adult attending a weight control exercise. The subjects of this study consisted of 81 adult in some areas of Daegu. Their weight, height, triceps, midarm circumference were measured and their dietary intake and eating behavior were obtained by using questionnaires. Anthropometry was conducted to determine obesity. Average age of men and women were 38.1 and 35.2 years old respectively. Their intake of energy and protein were 69.5% and 97.4% of RDA respectively. Energy intake of normal and obese group was 74.4% and 64.9% of RDA respectively. Protein intake of normal and obese group was 99.7% and 95.3% of RDA respectively There was a negative correlation between PIBW and energy intake, PIBW and carbohydrate intake, BMI and energy intake, and BMI and carbohydrate intake. A relative magnitude of factors affecting weight decrease rate was analyzed by Stepwise multiple regression analysis. Overall results about relative influence of independent variables to dependent variable(weight decrease rate) indicated that the BMI(p<0.01) was the most significantly correlated with weight decrease rate in all subjects. The results of this study suggest that the extensive nutrition education in weight control program should be emphasized to prevent obesity early.

The study suggests the possibility of using internet of things for a dietary intake survey. The development scenario of the dietary intake survey was composed of a weighing sensor for measuring food weight, bluetooth module for communicating through smart-phones, and smart-phone application. The weighing sensor attached to the bottom of utensils was designed to measure the weight of initial food & food eaten, and the results were transmitted to the smart-phone through the bluetooth module. The exclusive application in the smart-phone displayed the results of the amount of food intake, calorie intake, and eating rate. Through this system, subjects could continuously monitor their dietary intake & eating rate and recognize their actual eating environment, which leads to prevent overconsumption of food intake & form balanced eating habits. Based on this system, we need to consolidate and develop a weight control program.

A study was conducted to determine the effect of environmental temperature and level of food intake on plasma concentration of thyroid hormones. Three dairy heifers were used in an experiment which consisted of three levels of chamber temperature (10, 20 and $30^{\circ}C$) and three levels of food intake (100, 75 and 50% of recommended requirements). The analysis showed significant effects of environmental temperature on plasma triiodothyronine concentration, rectal temperature, respiration rate and heart rate but not on heat production. The range of plasma triiodothyronine was 2.51~1.79 ng/ml when the environmental temperature varied from 10 to $30^{\circ}C$. Effects of feed intake level were significant for heart rate and heal production. Heat production decreased from 25.9 to $20.0kJ/kg^{0.75}{\cdot}h$ when the TDN intake decreased from 66.3 to $35.1g/kg^{0.75}{\cdot}d$. There was no interactive effect of environmental temperature and feed intake level. Plasma triiodothyronine concentration decreased under high environmental temperature without any changes in heat production. The effects of environmental temperature and feed intake level on the physiological function of thyroid gland, as indicated by the relative circulating rate of thyroid hormones, were found to be clear.

This study was designed to investigate calcium intake, the ratio of Ca intake versus R.D.A. (Recommended Dietary Allowance) for Ca, apparent Ca absorption rate, and Ca sources of food among school children in Korea. One hundred school children aged from 6 to 12 years were engaged in this study; 33 subjects were from farming village neal Seoul, and 67 children from big cities. Two days of food consumption records and feces collections of the subjects had been done from April 1978 to June 1978. The following observations were made in the present study; 1) Average Ca intake of total subjects was $457{\pm}214mg$ which is only 76% of R.D.A. for Ca. Calcium intakes for farming village children was higher than that of the subjects from big cities (p<0.05). 2) Survey on the food sources of Ca revealed that the amount of Ca taken from cereals averaged 120 mg (22.3% of total Ca intake), 111 mg (24.3%) from fruits and vegetables, 176 mg (38.5%) from meats, poultry, fishes and eggs, and only 68 mg (14.9%) was supplied by milk and milk products. From the data collected, following observations were made; a) No significant difference in Ca intake from cereals was found between village children and the ones from big cities. b) Average Ca intake from fruits and vegetables of city children was significantly higher than that of village children (p<0.005) with the values for 133 mg for the former and 64 mg for the latter. c) For the group of meats, poultry, fishes and eggs, significantly higher intake was found in village subjects than city children (p<0.0005) with the values of 340 mg and 95 mg, respectively. d) Contrarily, Ca intake from milk and milk products was significantly (p<0.0005) much higher in the city children (98 mg) than village ones (7 mg). 3) Apparent Ca absorption rate of total subjects was 51%; 44% for village children and 54% for city children. Ca absorption rate tends to be higher in the city subjects but no significant difference was noted.

This paper has studied the nutritional iron status of adults in the city of Taegu. The subjects of the experiment were twenty six men and women living in the city of Taegu. The iron intake was 26.1mg for men and 17.1mg for women, which were respectively 217.5% and 95% of RDA. For men heme iron was 5% and nonheme iron, 95% for women heme iron was 5.8% and nonheme iron, 94.2%. The absorption rate of dietary iron was 6.2% for men and 9.1% for women. The hemoglobin was 14.5g/dl for men and 11.9g/dl for women, and the rate of developing anemia was 8.3% in men and 57.1% in women. The serum ferritin was 57.8ng/ml with men, which was found to be normal, and 14.7ng/ml with women, which showed that 57.1% of women were in the condition of iron depletion or iron deficiency anemia. The rate of developing anemia resulting from the deficiency of serum ferritin was as high as that from the deficiency of hemoglobin. The correlation between iron intake based on the dietary record, and energy intake, vegetable protein intake and dietary fiber intake was found to be positive. So was the correlation between the iron intake, and hemoglobin, serum ferritin and urinary iron excretion. There was also a positive correlation between hemoglobin, and hematocrit and serum ferritin. The correlation between fecal iron excretion and serum ferritin was positive. Fecal iron excretion and urinary iron excretion can be complemented by iron intake but the fact should be considered that 95% of iron intake is nonheme iron, which is difficult to absorb. Based on the above-mentioned things, serum ferritin and hemoglobin can be used as the standards of measuring anemia. As women in their child bearing years show the high rate of 57.1% of developing anemia, the more thorough nutritional education of iron is required.

The purpose of this study was to compare nutrient intake, health-related factors, and risk factors for metabolic syndrome and to investigate the prevalence odds ratio according to fruit and vegetable intake among middle-aged Korean men. Subjects included 1,677 men aged 40 - 64 years. The average intake of fruits and vegetables was $578.48{\pm}5.90g/day$. Forty-nine percent of the subjects were categorized into the deficient group based on the intake of fruits and vegetables, and the other subjects were categorized into the adequate group. There was a significant difference in the nutrient density per 1,000 kcal of energy, minerals, vitamins, and dietary fiber between the fruit and vegetable intake groups (p<0.001). In terms of health-related factors, only the current smoking rate in the deficient group (57.9%) was higher than that in the adequate group (45.4%) (p<0.001). There was no significant difference in the risk factors for metabolic syndrome between the fruit and vegetable intake groups. Proportion of serum triglycerides (42.6%) was the highest at a rate that exceeded the criteria for risk factors for metabolic syndrome, but systolic blood pressure (21.7%) showed a very low rate. The fasting blood glucose, serum triglycerides, and diastolic blood pressure were significantly higher in the deficient group than in the adequate group (p<0.05). Prevalence of metabolic syndrome was 31.2%. OR for prevalence of metabolic syndrome related to fruit and vegetable intake was 1.270 times higher in the deficient group than in the adequate group (p<0.05). Also, when the daily fruit intake was increased by 100 g, the prevalence of metabolic syndrome was reduced by 0.948 times but it was not related to the vegetable intake. The results of this study can be used as the basic data to establish the guidelines for fruit and vegetable intake for prevention of metabolic syndrome in middle-aged men.
