The purpose of this study is to computerize all the necessary information on the daily food value and nutritional status for individuals and groups. In this research, a FOCUS-16jXT (16 bit personal computer ) compatible with IBM-PCjXT was used, and the database files and programs were created by using the dBASEIII package. The food life evaluation system consists of 3 subsystems of Reference, Nutrition Status Assessment and Food Source. The findings are summerized a8 follows: 1. Reference: This subsystem enables users to proceed to the next step, if necessary, by describing each subsystem. 2. Nutrition Status Assessment. 1) Food Habit Assessment: This subsystem determines whether the user has a good food habit or not, based on the answers for ten questions about daily food life. 2) Obesity Assessment: This subsystem calculates Broca index, which is used as a indicator of obesity. 3) Nutrient Intakes: When personal data such as age, sex, weight, height and food consumptions are input, it is possible to calculate the followings. i) Comparison between the amounts intaked and the recommended dietary daily allowances of various nutrients ii) Nutrient intakes from each food group and their composition rates for the nutrients iii) Nutrient intakes per unit body surface area iv) Composition of lipid intake 3. Food Sources: The appropriate food sources for the lacking nutrients will be recommended to the subjects.

Objective: An experiment was conducted to examine the effect of dietary supplementation of dried and ground foliage of black gram (Vigna mungo L.) on feed intake and utilization, and production performance of crossbred lactating cows. Methods: Eighteen lactating crossbred (Bos taurus${\times}$Bos indicus) cows (body weight $330.93{\pm}10.82kg$) at their second and mid lactation (milk yield $6.77{\pm}0.54kg/d$) were randomly divided into three groups of six each in a completely randomized block design. Three supplements were formulated by quantitatively replacing 0, 50, and 100 per cent of dietary wheat bran of concentrate mixture with dried and ground foliage of black gram. The designated supplement was fed to each group with basal diet of rice straw (ad libitum) to meet the requirements for maintenance and milk production. Daily feed intake and milk yield was recorded. A digestion trial was conducted to determine the total tract digestibility of various nutrients. Results: The daily feed intake was increased (p<0.05) with the supplementation of black gram foliage. Although the digestibility of dry matter, organic matter, crude protein, and ether extract did not vary (p>0.05), the fibre digestibility was increased (p<0.05), which ultimately improved (p<0.05) the total digestible nutrients content of composite diet. Although, the average milk yield (kg/animal/d) and composition did not differ (p>0.05) among the groups, milk yield was increased by 10 per cent with total replacement of wheat bran in concentrate mixture with of black gram foliage. The economics of milk production calculated as feed cost per kg milk yield (INR 10.61 vs 7.98) was reduced by complete replacement of wheat bran with black gram foliage. Conclusion: Black gram foliage could be used as complete replacement for wheat bran in concentrate mixture of dairy cows in formulating least cost ration for economic milk production in small holders' animal production.

This study was designed to investigate the effects of calcium supplementation on calcium metabolism in seven healthy college women, aged from 19 to 21 years old. For this purpose, metabolic studies were conducted for two weeks. During the first week, the subjects ate experimental diet which nutrients composition was similar to their usual intake. And during the consecutive second week, they ate the same experimental diet supplemented with 500mg of calcium daily. The results were summarized as follows ; 1) Fecal excretion of calcium increased significantly (P<0.05), but urinary excretion of that did not show any change after supplementary intake of calcium. 2) Mean apparent calcium absorption was 28.5% and retention was 182mg/day when subjects ate the experimental diet without calcium supplementation. Calcium retention was significantly ate the experimental diet without calcium supplementation. Calcium retention was decreased to 24.1% by additional intake of calcium. 3) Phosphorus balance did not show any change after additional intake of calcium. 4) Serum calcium level was also not changed by additional intake of calcium. 5) Serum calcium level increased significantly(P<0.05) but serum phosphorus level did not show any change after additional intake of calcium. The above results showed that supplementation of 500mg calcium daily can be helpful to increase calcium retention as well as the peak bone mass in young women eating usual Korean diets.

This study was carried out to develop nutrition education materials for nutrient intake and the prevention of disease for the elderly and to test their effects on the health-related matters and nutrition intakes after nutrition education. The mean age of the subjects was 71.6 years old. Diet adjustment for health increased a little bit from 2.2% to 11.1% after education but with no significance. The highest reported chronic illness was hypertension. The drinking of the subjects decreased a little bit after their education but wasn't significant. There were no significant changes to the frequency of food consumption across all the items after education, but there was a small increase to the daily intake of milk and dairy products and fruits and to a balanced diet three times per day. There was a significant increase in the intake of such nutrients as energy(p<0.05), protein(p<0.01), lipid(p<0.05), phosphorus(p<0.05), sodium (p<0.05), vitamin $B_2$(p<0.05), vitamin $B_6$(p<0.05), and niacin(p<0.001) after education. Those findings show that nutrition education provided to the elderly had no clear effects on the items that required memorization such as nutrition knowledge but did have some effects on dietary life. If the nutrition education requiring memorization is provided repeatedly with data supplemented, more effective nutrition management will be possible.

As the severity of environmental pollution increases, the foodstuffs are contaminated more the ever. There are 40 kinds of heavy metals that we are able to consume through the heavy metal contaminated-foodstuffs. Arsenic, lead, cadmium, and chromium out or them have been know to be a potential cause for a alzheimers disease, kidney diseases, and cancer. However, research data on the daily intakes of such heavy metals are limited. This study was performed to evaluate the daily intakes of nutrients and the dietary heavy metals of the college women living in Choongchung-NamDo Area, where had been reported to have high contents of heavy metals for the seafoods. We also investigated the blood levels of the heavy metals. The mean age, height, weight, BMI and percent ideal body weight(PIBW) of the subjects were 20$\pm$1.0yr, 158.4$\pm$0.7cm, 55.1$\pm$1.4kg, 22.4$\pm$.04, and 103.3$\pm$2.5 %, resp-ectivly. The mean of daily energy intake was 1,717.03$\pm$55.99kacl/day(86% of RDA for women). The ratio to energy from carbohydrate, fat and protein was 60: 24: 16. Daily intakes of Vit A, Vit B$_2$, CA, and Fe were under the RDA for those nutrients. The mean adequate ratio of the subjects was 0.92 . The daily intakes of heavy metal, such as As, Pb, Co, Cr and Mn , were 1.80$\pm$0.27mg, 75.21$\pm$4.12$\mu\textrm{g}$, 21.12$\pm$12.34$\mu\textrm{g}$, 60.07$\pm$6.24$\mu\textrm{g}$ and 6.23 $\pm$0.12mg respectively. the blood levels of As, Pb, Co, Cr and Mn were 16.10$\pm$2.10$\mu\textrm{g}$/dl, 4.32$\pm$0.58$\mu\textrm{g}$/dl, 0.02$\pm$0.01$\mu\textrm{g}$/dl, 4.23$\pm$0.41$\mu\textrm{g}$/dl, and 4.40$\pm$0.21$\mu\textrm{g}$/dl, respectively. In conclusion, daily intake of heavy metals for the college women living in Choongchung-NamDo area was lower than that of WHOs re-commendation, however, the blood levels of each heavy metals were higher than those of Japanese, american, and italian, There were no correlations between the dietary intakes and blood levels of each heavy metals.

The survey was conducted for the period from 25 th to 29 th July, 1990. The survey area were selected the mountain area in Kang Won Province. Intake of foods and nutrients of all members in the households surveyed by means of questionnaire was computed based on number of meals a day. On the other hand, daily intake of nutrients by an individual was calculated by sex, age and type of work based on the conversion rate of RDA (Korean Recommended Dietary Allowances for Adult). 1. Status of food intake. The average food intake per person per day in surveyed area was 1103.49 g. The total intake of food was consisted of 44.17% grains, 23.31% vegetables, 10.66% fruits, respectively. These findings led us to the conclusion that people in the surveyed area depended heavily on plant foods. 2. Status of nutrient intake, 1) The average intake of Calorie was 2567.54 Cal Per day, which was slightly higher than 2500 Cal of RDA. 2) The average Intake of protein was 82.92g per day, which was higher than 70g of RDA. Though the quantity was above the RDA, it was largely from plant foods 3) The average intake of calcium was 383.93 mg per day, which was much lower than 500 mg of RDA. 4) The average intake of iron was 11.88 me per day, which was nearly the same quantity as 10 mg of RDA. 5) Intake of vitamin group were high among the inhabitants than recommended by RDA 3. The Kinds of food intake The kinds of food intake in surveyed area were totally 66 different kinds. 4. Economic status. As for the education level, almost of the food handlers finished the primary school and the average monthly income was 364,600 in surveyed area. Households used gas(100%) for fuel.

The present study was conducted to evaluate the food and nutrients intakes of stomach cancer patients in the Daegu and Gyeongbuk areas in order to find out the dietary risk factors for stomach cancer. The subjects of the study were 102 patients who had recently been diagnosed with stomach cancer at the Gyeongbuk National University Hospital. The control subjects were 105 people including patients from the Department of Orthopedic Surgery and healthy volunteers who did not have any gastrointestinal diseases. Estimates of nutrients intakes were determined from the food intake frequency data obtained by individual interviews using questionnaires. The mean daily calorie intakes of the control and the case groups were not significantly different. However the energy intake from protein was significantly higher in the case group as compared to the control group. With regard to the nutrients intakes, the case subjects consumed significantly higher amounts of nutrients such as protein, calcium, sodium, phosphorus and niacin than the control group. The case group showed a tendency to consume higher amount of protein, fat, calcium and iron from animal food sources. In the present study dietary factors which were suspected as being risk factors for stomach cancer included high consumption of animal foods, specific nutrients such as protein, sodium and niacin, specific food groups such as meat, spices, and low consumption of fruits and mushrooms. Therefore, it is recommended that more extensive and systematic surveys be conducted to confirm the risk factors for stomach cancer, taking into consideration the dietary cultural characteristics of this region.

This study was performed to investigate the effect of family type on the nutrient intake and nutritional status in elderly women. Blood samples and anthropometric data of elderly women aged from 60 to 78 years were collected in 1996, who visited a health examination center in Seoul to screen their health status. They were divided into two groups by their family type, one was extended family(extended family elderly, n=37) and the other was independently living(independently living, n=29). Nutrients intake was measured by interview using a simplified questionaire. Albumin, cholesterol, triglyceride(TG), hemoglobin (Hb), hematocrit, Ca, Mg, and alkaline phosphatase activity of serum were analyzed. Intakes of energy, protein, carbohydrate, Fe, vitamin A, niacin, thiamin, riboflavin, and vitamin C were not different between the two groups. However, fat and Ca intakes were higher(p<0.05) in extended family elderly than indepen dently living elderly. There are no significant difference in hematocrit value and serum concentrations of Hb, TG, and Ca. Serum Mg and cholesterol levels tended to be higher in extended family elderly. However, serum albumin level was lower(p<0.05) in extended family elderly. These results show that the indepen dently living elderly women had intakes of daily energy, fat and Ca compared to the extended family elderly. Therefore, the nutritional education for the independently living elderly will be focused on the health risk resulted from less intakes of Ca and total energy.
