The purpose of this survey was to investigate the nutritional status of special working persons related to health status, nutrient intake and living environment. The survey was conducted on workers in 9 general hospitals and 2 factories from Nov. 24 in 1979 to Jan. 20 in 1980. Nurses, medical doctors on intership or residency, and factory workers were chosen as subjects because of their irregular working hours, i.e., they sometimes work during the day and. sometimes at night. The total number of subjects was 417 for nurses, for medical doctors was 91, and was 216 for factory workers, all together 724 subjects were investigated. The results obtained are summarized as follows: 1) Average nutrient intake of subjects per day. For nurses the caloric intake was 1743 Kcal. This was composed of carbohydrate 251g(57.6%), protein 81g (18.5%), and fat 46g (23.9%). Other nutrient intake, such as iron (16mg), thiamin (0.98mg), riboflavin (1mg) was lower than the recommended dietary allowance. For male medical doctors, the caloric intake was 2064 Kcal, This was composed of carbohydrate 288g (55.8%), protein 102g (19.8%) and fat 56g (24.4%). Other nutrient consumption, such as riboflavin (1.31mg) was lower than the recommended dietary allowance. For female medical doctors, the caloric intake was 1909 Kcal. This was composed of carbohydrate 156g(53.7%), protein 90g (18.9%) and fat 58g (27.4%). For male factory workers, caloric intake was 1699 Kcal. This was composed of carbohydrate 317g(74.5%), protein 64g (15.0%) and fat 20g(10.5%). Other nutrient intake, such as vitamin A (4765IU), ascorbic acid (46mg) and riboflavin (1.11mg) were lower than the recommended dietary allowance. For female factory workers, the caloric intake was 1630 Kcal. This was composed of carbohydrate 287g (70.5%), protein 65g (15.8%) and fat 25g (13.7%). Other nutrient consumption, such as iron (15mg), riboflavin (1.04mg), ascorbic acid (42mg), and vitamin A (4334IU) was lower than the recommended dietary allowance.

Objectives: The aim of this study was to assess an association between nutrient intake and prevalence risk of deciduous dental caries among preschool children. Methods: A total of 922 children aged 3 to 5 years was selected from the database of Fourth Korean National Health and Nutrition Examination Survey(KNHAINS). Data were included socio-demographic characteristics, oral health related behaviour, nutrient intake(carbohydrate, protein, fat, calcium, phosphate, iron, sodium and potassium), and oral health status(dft index). To assess the crude and adjusted associations, logistic regression analysis were applied considering a complex sampling design. Results: Children who were more consumed protein, calcium, phosphate, iron and sodium had slightly lower prevalence risk of deciduous dental caries after adjusting for socio-demographic characteristics and oral health related behaviour. Moreover, prevalence risk of the highest intake of phosphate and sodium(3rd tertiles) was significant lower than that of the lowest intake(1st tertiles). Conclusion: The nutrient intake was slightly associated with the prevalence risk of deciduous dental caries.

The purpose of this study was to examine nutrient intakes, food and daily habits, and serum lipids for female college students. The subjects consisted of 70 female college students aged 20 to 29 years old. Their dietary intakes were assessed by means of 24 hour dietary recall method. Food models and other measuring tools were also used. Concentrations of serum lipids were measured. The energy intake of the subjects averaged 1837Kcal, whereas the expended energy was 1871Kcal. The subjects consumed 310g of carbohydrates, 66g protien, 37g lipid, 14mg iron, 586mg calcium, 513R.E. vitamin A, 1.0mg vitamin B1, 1.3mg vitamin B2 1.5mg niacin, and 69mg vitamin C, respectively. Vitamin A and iron intakes were lower than the RDA. The percentages of total calorie from carbohydrate, fat, and protein were 67%, 18%, 14%, showing desirable calorie construction. The mean serum triglyceride(TG), cholesterol (Chol), HDL-Chol and LDC-Chol concentrations were 72.4mg/dl, 161.3mg/dl, 44.5mg/dl, and 102.3mg/dl, respectively. All of these values seem to fall in the desirable range. There were positive correlations between serum Chol and HDL-Chol or LDL-Chol or TG ; negative correlations between serum Chol and HDL-Chol/LDL-Chol ratio, between serum TG and HDL-Chol or HDL-Chol/LDC-Chol ratio.

This study was conducted to evaluate the trace elemental nutritive values of soil and forages collected from southwestern part of the province of Punjab, Pakistan. Soil and forage samples were collected fortnightly for two seasons. The concentrations of some trace minerals varied greatly among seasons and sampling periods. Seasonal effects were found in all soil micro-minerals except zinc, while forage iron, zinc, and selenium were affected by seasonal changes. Sampling periods effects were observed in all soil minerals and in forage copper, iron, zinc, and manganese only. All soil mineral levels except cobalt and selenium were sufficiently high to meet the requirements of plants for normal growth during both seasons. In contrast, soil Co and Se levels were severely deficient during both seasons and considered inadequate for plant growth. Soil Fe, Zn, Co, and Se levels were higher, and Cu and Mn lower during winter than those during summer. Forage Zn levels during summer were at marginal deficient levels, and in contrast, all other forage micro-minerals were within the required range for ruminants during both seasons. Although forage mico-minerals were within the range required by the ruminants, they were not sufficiently high to prevent the predisposition to various diseases caused by nutrient deficiency. Consequently, grazing animals at this location need continued mineral supplementation of these elements with a mixtures of high bio-availability rather than of high micro-mineral contents to support optimum ruminant productivity.

타이타늄은 구조용 금속 중 알루미늄, 철, 마그네슘에 이어서 네 번째로 풍부한 금속이지만, 금속으로의 제련이 어려워 희소금속으로 분류되고 있다. 특히 타이타늄의 제련공정은 에너지 다소비형 공정이다. 타이타늄 스크랩으로 잉곳을 제조하면 에너지 소비량과 CO2 발생량을 약 95 %까지 절감할 수 있다. 그러나 스크랩 중의 철분과 산소 등의 불순물을 제거하기 어려워 리사이클링 되는 양은 한정되어 있다. 일반적으로 고품위 타이타늄 스크랩은 순타이타늄 스펀지의 재용해 공정에 투입하여 희석하고, 저품위 스크랩은 페로타이타늄 제조용 원료로 사용되고 있다. 본 논문에서는 이러한 타이타늄의 리사이클링 기술을 이해하기 위해 타아타늄의 제련기술과 리사이클링 기술에 대하여 고찰하였다.

This study was designed to assess the effect of a meal service for home-staying urban elderly people with low-income on their protein nutrition status and serum lipids. One hundred and eighty three subjects, who had already completed the first nutritional survey were assigned to two groups : meal served(served) and non-meal served (non-served). A meal approximately containing one half of the RDA for energy, protein, calcium and iron was served as lunch everyday to served group. After 6 months of meal service, the second nutritional survey was done and changes of parameters were analyzed with paired t-test. Served females showed significantly increased intake of energy while non-served females showed significantly decreased intakes of energy, protein and fat after 6 months. Served males were observed with significantly higher intake of energy, fat, vitamin A, niacin and ascorbic acid, whereas intake of vitamin A was lower in non-served males. Arm circumference of both served and non-served females were significantly lowered after 6 months. Mean DBP of served males was significantly lower, while SBP of served females was significantly higher after 6 months of meal service. Serum total protein, serum albumin, serum cholesterol and LDL-cholesterol were significantly increased within normal range regardless of gender and meal service. But HDL-cholesterol was significantly higher in only served elderly subjects after 6 months. (Korean J Community Nutrition 1(2) : 228-238, 1996)

The nutritional status of 362 elderly men and women in Chung-bud area was evaluated in terms of their nutrient intakes, biochemical and anthrophometric measurements by interviews with questionnaires from August to October 1996. Mean intake of all nutrients except ascorbic acid did not meet the RDA for this sample. Protein, vit A, reboflavin, calcium were the most likely to be deficient on the basis of propotions of elderly consuming less than 75% of the RDA. The subjects nutrient intake was significantly affected by gender, marital status, number of family, family composition, educational level, pocket money, and region. Men in rural areas and women over 75 in urban areas were the most vulnerable groups with nutritional deficiency. According to serum biochemical indices, mean level of cholesterol, triglycerides, LDL, total protein, albumin and iron belonged to normal range but mean level of HDL showed below the normal range. More elderly men and women in urban areas showed a higher percentage of abormal level of cholesterol, triglycerides, LDL and HDL than those in rural areas. More elderly men and women in rural areas had abnormal levels of RBC, Hematocrit and hemoglobin compared to those in urban areas. Mean height and weight of elderly men was 161.4cm and 56.2Kg, respectively and 149.1cm and 50.5kg for women. The elderly in rural areas were taller than those in urban areas but had less weight, MAC, TSF, MAMC. Mean BMI of this sample belonged to normal range. However, the elderly in rural areas had a higher rate of underweight and lower for overweight than those in urban areas. The elderly in urban areas had higher blood pressure than those in rural areas.

The purpose of this study was to compare the consciousness of health status and nutrient intake of farmers in Korea. Eight hundred were surveyed by rural leaders of Rural Development Administration(RDA), composed of 35.1 % male and 64.9% female. Data collection included personal & family situation by Interview method for influencial factors of health status. Food intake was determined by semiquantitative food frequency method with 65 kinds of foods. 32.5% of the subjects were elementary school graduates, younger age groups and males had higher levels of education. Mean family numbers was 4.2 persons. In the concept of disease prevalence, gender difference existed. Liver and heart ailments were frequent in males and waist pain and urinary complaints in females, and schoulder pain and nervesness were frequently prevalent to all farmers. The energy intake of farmers was 2000Kca1/day, 19:16:65 of PFC(protein, fat, and carbohydrate) ratio was approached at recommended composition of energy. But calcium and iron were lower than Korean Recommended Dietary Allowences(KRDA), Vitamin A, thiamin, niacin, and vitamin C were over of KRDA, but riboflavin, pyridoxin, and vitamin I were lower than KRDA. The nutrient intakes of poor health groups were significantly lower than those of healthy. In fatty acid composition, monounsaturated fatty acids(FA) intake was higher than that of saturated FA. The CMI (Cornell Medical Index) and Farmers' syndrome were significantly correlated with personal factors, such as height, number in family, education level, and working level. But the correlation of health status with nutrient intakes were only weakly significant. Depending on the regression analysis, Farmers' syndrome explanation about nutrient intake was low(R2 was only 0.01 more or less), but some nutrients (energy, niacin, pyridoxine, vitamin E, and lipids) could explain this significantly. It was concluded that body complaints of farmers could ameliorate with good nutrition.

Nutrition is one of the factors influencing cognitive functions. But, the role of nutrition on cognitive functions within the elderly is recognized to a lesser degree. The aim of this academic endeavor was to analyze the affiliation between nutritional status and cognitive functions of the elderly in Korea. 316 subjects, of 114 male and 201 female aged above 65 years, were gathered from university hospital clinics, Elderly Welfare Centers, and Health Welfare Centers located in the district of Seoul, Gyeonggi province, and Incheon in Korea. The cognitive function was tested by the Korean-Mini Mental State Examination (K-MMSE) questionnaire. Nutrition intake was assessed by a 24-hour recall, a food frequency questionnaire (FFQ). Nutrition adequacy and quality were assessed by the Nutrition Screening Initiative (NSI) checklist, the nutritional adequacy ratio (NAR), and the mean adequacy ratio (MAR). The elderly with normal cognitive function status displayed significantly higher levels of calcium, riboflavin, thiamin, folate, vitamin C, vitamin E, vitamin B6, phosphorous, potassium, iron, niacin, zinc, animal fat, animal protein, polyunsaturated fatty acids, total protein, vegetable oil, vegetable protein, fiber than levels of the elderly with moderate cognitive impairment. The K-MMSE score positively correlated with of high consumption of pork, white radish, sea mustard, tomato, tangerine, grape, apple, and ice cream, and K-MMSE was negatively associated with high intake of potato, anchovy, fish cake, and mushroom. The findings suggest that nutritional status is affiliated with cognitive function within the elderly of Korea. The consumption of variety of foods and nutrients ensures adequate cognitive function in the Korean elderly.

In order to provide basic data for the means to improve food situation and nutritional status of those supported by the National Basic Livelihood Security System (NBLSS), we examined household food insecurity and nutritional status of children under the support of NBLSS. This study included 209 children aged 3-12 years (99 boys and 110 girls) and their caretakers. We measured house food insecurity using Radimer/cornell Scale, children's body sizes and nutrient intake by semi-quantitative food frequency questionnaire, and caretakers' nutritional management skills. Only 9.6％ of the households were in food secured (FS) while 8.1％ were in household food insecured, but without hunger (HFI), 42.1％ were in adult food insecured with hunger (AFI), and 40.2％ were in child hungry (CH). Important predictors of food security were nutritional management skills of the caretakers as well as their education, but neither income nor food expenditure of the households. Mean energy intake of the children was 86.0％ of the Korean Recommended Dietary Allowance (RDA). Intakes of protein, phosphorous, vitamin A and B$_1$ were relatively high ranging from 112.3％ to 124.4％ of the RDAs while those of calcium, iron, niacin, vitamin C were low showing 74.8-83.3％ of the RDAs. Height, weight and weight/height ratio were close to the reference levels. Lower nutrient intakes of children were observed as the households were more food insecured. However, nutrient intakes and body sizes of children did not differ as a function of household socioeconomic status representing by income, food expenditure and caretakers' education. Results of this study suggest the importance of food security and nutritional management skills for the children's nutrient intakes. Concerning this matter, a need for nutrition education in the program for NBLSS was discussed.
