The study was conducted to investigate the factors associated with bone mineral content (BMC) changes among early pubertal aged girls. Two hundred and thirty girls between 9 to 11 years of age participated in (our surveys over 2 year period. During each survey, dietary intakes were collected with 3-day food records, BMC of left leg's calcaneus were measured by PIXI (Lunar Ltd.) and body composition was measured by bioimpedance method (Inbody 3.0 Biospace Co. Ltd, Seoul, Korea). Mean values of BMC increased in consecutive measurements -1.48 g, 1.54 g, 1.61 g and 1.66 g. The change of BMC between the first and last measurements was significantly positively correlated with % body fat, negatively correlated with BMC at the baseline (p < 0.05). Change of BMC was also significantly positively correlated with % change of lean mass and mineral mass between the first and last measurements. Nutrient intakes during the study period were calculated as mean daily intakes from all surveys. Mean daily intakes of Vit. C and Vit. $B_6$ were positively and isoflavone intake was negatively correlated with changes of BMC (p < 0.05). In stepwise regression of BMC change with body composition and nutrient intakes, baseline values of BMC, weight, BMI and age, % change of mineral mass during the study period, mean intakes of isoflavone, Vit. $B_6$, protein, carotene and zinc were significant explanatory variables ($R^2=0.38$, p <.001, F = 32.39). The results imply that the change of BMC among early pubertal aged girls are associated with some body composition and intakes of certain nutrients.

Effects of alchohol and fat content in a balanced diet on chemical composition and morphology of liver were investigated in growing rats. Fourth eight male rats of Sprague-Dawley strain weighing about 160g were divided into 4 groups ; high fat diet group, alcohol-administered high fat diet group, low fat diet group and alcohol-administered high fat diet group, low fat diet group and alcohol-administered low fat diet group. High and low fat diets supplied 30% and 12%, respectively, of total calorie intake from fat, and alcohol was given by adding ethanol in drinking waster at 10%. Diets contained adequate amounts of all nutrients required for rats, including lipotrpoic agents(choline and methionine) to minimize effects of factors other than alcohol on liver damage. Ratios of liver weight to body weight were statistically different among groups. Liver/dody weight ratios alcohol-administered rats were significantly higher than those of non-alcohol groups after 6 weeks treatment. Although total lipid and triglyceride per gram liver were increased in alcohol-administered rats, especially low fat diet fed rats, the values were not significantly different. Opticmicroscopical observation revealed increase in cell size and no change in morphology of liver. Examination of hepatocytes by electron microscopy showed that fat droplets were observed in all groups but enlarged in the alcohol-administered low fat diet fed rat. Contents of protein, cholesterol and phospholipid were not affected by alcohol consumption. The level of lipid peroxide was significantly lower in the livers of alcohol-administered rats than in the livers of non-alcohol groups. The results of this study indicate that even moderate alcohol drinking and dietary fat content did not affect any significant change in composition and morphology of liver until 6 week treatment but that even moderate alcohol drinking caused some signs of steatosis of liver.

This nutritional survey was conducted from January 20 to February 8, 1994, in order to investigate the nutritional knowledge, food habits, nutritional attitude, food preferences and nutrient intakes of housewives living in Andong district, rural area of Korea. The subjects of this survey were 181 rural housewives living in Andong area. The completely answered questionnaires were analyzed for nutritional knowledge, food habit, nutritional attitude, food preferences and nutrient intakes of rural housewives. The results obtained are summarized as follows: The subjects had a high level of perceived knowledge (79.9%), that is the knowledge that each subject believed she had, but the accuracy of the knowledge was only 66.6%. The average nutritional knowledge score was 7.93 out of possible 15 points, and food habit score was 5.08 out of 10 points. Most of the subjects belonged to "Fair" or "Poor" food habit group, which is considered to be relatively bad. With increasing age, the percentage of perceived knowledge, accuracy, and nutritional knowledge score were getting lower. Food habit score and nutritional attitude score were getting lower with increasing age, too. The correlation between nutritional knowledge score and food habit score was low(r=0.01). The correlation between nutritional attitude score and food habit was low, too(r=0.15). Food preferences for kimchi, cooked rice, potato, milk, beef, chicken, and carrot were high. Average calorie and protein intakes of the subjects were 1915.7㎉ and 77.0g respectively. The ratio of caloric nutrients intake was carbohydrate 65.9%, protein 14.9%, and fat 19.2%.

This study was conducted to investigate the risk of chronic disease as predicted by abdominal obesity in Korean adult females. Data on 2,738 adult females aged 40~64 yrs was obtained from the 2013~2014 Korean National Health Nutrition Examination Survey. The subjects were divided into normal (n=1,835), abdominal obesity (AO, n=73), and BMI-diagnosed abdominal obesity (BMI-AO, n=505) groups based on the NCEP-ATP III guidelines and by applying the KSSO definition regarding waist circumference. Triglyceride blood levels, fasting blood sugar levels, systolic blood pressure, and diastolic blood pressure were higher in the AO and BMI-AO groups than in the normal group. The HDL-cholesterol levels of subjects in the two abdominal groups were lower as compared to those of subjects in the normal group. The mean adequacy ratio was lower among subjects in the AO and BMI-AO groups than among those in the normal group. Moreover, the NAR and INQ scores of some micro-nutrients in both of the abdominal obesity groups were lower than those in the normal group. Both the AO and BMI-AO groups showed significantly higher risks of hypertriglycemia, hyperglycemia, hypertension, hypoHDL-cholesterolemia, and metabolic syndrome than were shown by the normal group. Notably, as compared to the normal group, the AO group showed higher risk of hypercholesterolemia, hyperLDL-cholesterolemia, hypertriglycemia, and metabolic syndrome than did the BMI-AO group. This finding suggests that it is essential to develop prevention programs including programs for those with abdominal obesity despite their having a BMI within the normal range.

The objective of this work was to evaluate the growth performance, feed intake, slaughter characteristics, meat quantity and quality characteristics of Hanwoo steers fed with Italian ryegrass (IRG) silage (TRT). IRG silage consisted 11.70% protein, 2.84% ether extract, 53.50% dry matter digestibility and 63.34% total digestible nutrients. The daily weight gain and feed conversion ratio of TRT were significantly (p<0.01) higher than that of control diet (CON; fed rice straw) in the whole periods. However, the slaughter weight, dressing percentage, quantity grade and quantity traits (marbling score, meat color, fat color, and quality grade) of either TRT or CON were similar. Meat fed TRT diet showed higher crude fat and lightness (L*) value and lower moisture content and pH value compared with the CON diet (p<0.05). Overall the carcass yield was 12.5% higher than CON diet.

Current status of nutrient fortification in processed food in Korea were presented by analyzing the information shown on food labels. The obtained information was assessed by the regulations on food fortification in both Korea and other countries including Codex. The most current regulations were gathered from internet. The results are summarized as follows. 1. Major nutrients fortified were calcium, Vit C, Vit B complex, iron and fiber. The forfified foods were not limitted to certain food group with more frequent fortification in snackfoods, cereal, ramyun, retort pouch foods, milk, and youguart. The descriptive terms of nutrition label for the fortification were various including high, supplemented, added, source, fortified, and abundance though the difference among these terms were not distinct. 2. Current regulation on nutrition label requires to give the content of the fortified nutrient and % RDA. However not all of food items carry above information. Also some ingredients such as chitosan, DHA, taurine, $\omega$-3 fatty acid, chondrichin, bifidus were supplemented mainly to the snack foods which FDA(USA) does not allow to be fortified. 3. The nutrient most frequently fortified was calcium and general practice of fortification appears to follow the regulation in Korea. Presently the regulation itself is not well described, this nutient fortification can cause toxic effect. Since calcium was supplemented to wide range of food group consumers who are not conscious of the safe upper limit may intake the fortified food up to the level of 2g/day. 4. For the effective fortification in Korea, the regulation on fortification should be reformed in accordance with the international guideline Codex and the regulations in other countries especially in America and Japan.

In this study, the food cost for the urban worker's living expenses was estimated for the Korea Labor Union. The urban workers living expenses are minimum of healthy and decency level expenses with allowances for minimum quality of life. Thus, the food cost should be enough for purchasing proper kinds and amount of foods which can supply sufficient nutrient to maintain health and which should reflect current food consumption patterns. To estimate the food cost, the Korean Recommended Dietary Allowances was used to calculate the amount of nutrients which should be supplied. The National nutrition survey and the Food balance sheet, were used to estimate the current consumption patterns for the kind and amount of food. To estimate price for each food item, the market survey was executed in six large cities. Also, to verify the estimated food cost, actual food costs were surveyed. For 5 kinds of model household, dietary allowances were calculated for the each nutrient. Using the Korean food guides, the number of serving for each food group were decided for the model households. In each food group, the amount and kind of foods were decided by the current food consumption pattern. The kind and amount of food were adjusted by the amount of calculated nutrient. When the amount of nutrient was between 90% and 110% of the recommended dietary intake, it was accepted. With these amount and kinds of foods, the food cost were calculated using the market survey. Considering extra expenses for the eating-out and processed foods, extra expenses are added. As a results, for single person family, the estimated food cost was 149,210won per month. For two, three, four and five person family, the estimated food costs were 245,179won, 381,182won, 501,669won and 687,980won per month, respectively. The estimated food cost were lower in the single and two person family than the actual food cost by the survey. The cost for eating-out gave major differences. In the future, to estimate food cost, the food consumption patterns for the different kind of household, sex and age should be studied carefully. Also, the pattern of eating-out should by analyzed.

Menstrual problem (premenstrual syndrome (PMS) and dysmenorrhea) is a common gynecological complaints among women in reproductive age. The aim of this study was to compare the effects of isoflavone and Cynanchum wilfordii for improvement of premenstrual syndrome, dysmenorrhea. Subjects were 30 college women in Busan, divided into three groups (CG; control group, n=10; IS group; isoflavone supplement group, n=10; CS group; Cynanchum wilfordii supplement group, n=10). They showed 5.0 or higher for menstrual pain when tested by the VAS. IS group was allocated a isoflavone pill (500 mg/day) for 8 weeks, and CS group was allocated a Cynanchum wilfordii pill (6 g/day) for 8 weeks. We administered a menstrual distress questionnaire (MDQ), and visual analogue scale(VAS). There were no differences among the three groups in general characteristics, nutrients intake, MDQ, or VAS. In the CG group, there were no differences in MDQ, or VAS after 8 weeks. In the IS group, negative emotions, behavioral changes, concentration, pain, autonomic nervous system response, water retention, and skin changes significantly improved (P<0.05). In the CS group, negative emotions, pain, autonomic nervous system response, and water retention significantly decreased after 8 weeks (P<0.05). Changes in negative emotion, pain, autonomic nervous system response, water retention, skin changes significantly improved in the CS group compared to the control group (P<0.05). VAS significantly decreased in the IS and CS groups (P<0.05). The decrease in VAS differed among three groups, with the CS group showing a larger decrease than the control group and IS group (P<0.001).

With increases in senior citizens and changes in family structure, the need for long-term care system for elderly is increasing, however, the capacity and environment of Korean facilities are very limited. Health and nutritional status of long-term care residents are worse than free-living elderly. In this study, general food service management and health care practices in long-term care systems were investigated. Questionnaire were sent to the directors of all 162 long-term care facilities in Korea and 81 returned the complete answers. The results showed 1) There are slow but steady increase in long-term care systems in Korea, however, the capacity is far from adequate. Less than 10,000 elderly were resided in the facilities. Most of the systems were free-nursing homes and supported by the goverment. Staffing structure revealed that most of the facilities had a director, a secretary, nurses, but only 21% of the systerm hired a dietitian. It showed the shortage of nurses, physical therapists, and dietitians. Therefore, food purchasing, menu planning, food delivery, and the other food service management processes are handled by non-professionals, such as director, secretary, or cooks. Modified fool frequency questionnaire were used to get the frequencies of each food items used in menu and a menu-analysis was made on the one-day menu provided by the facilities. The results showed relatively satisfactory in nutrients content and food frequencies., however, this was about what was used in menu, not what was eaten by the residents. Therefore this results did not tell that the food intake status of individuals. In most facilities general health checkup was done on a regular basis, and had residents with various chronic degenerative diseases, such as hypertension, neuralgia, stroke, arthritis, diabetes. But the items checked on health checkup included weight, height, blood and urine tests, X-ray test, which suggested that the checkup lists should be revised to accomodate the health problem of the aged today.

The purpose of this study was to evaluate the effectiveness of an intervention program using dietary consult and physical exercise conducted by public health center in Chuncheon city for obese adults. This study used a pretest-posttest design. The subjects were 58 out of 90 obese adults with body mass index (BMI) greater than $25kg/m^2$ who completed all education sessions for 8 weeks. Data on dietary habits, dietary behaviors, nutritional knowledge, anthropometric parameters and biochemical indices and daily nutrient intakes assessed by a 24-hour recall were collected before and after the intervention program., in order to evaluate program effectiveness. After the intervention, there were positive changes in exercise status and dietary habits and nutrition knowledge accuracy. Especially, the answer of 'I drink a cup of milk every day' were significantly improved (p<0.001), and the answer of 'I don't overeat', which is a dietary attitude question was significantly improved (p<0.05). Dietary intakes of most of nutrients were not significantly different between pre-test and post-test. But calcium (p<0.05), potassium (p<0.05), vitamin A (p<0.01), vitamin E (p<0.05), and folic acid (p<0.05) were significantly increased in the female group after the intervention. Weight (p<0.05), BMI (p<0.01), blood pressure (p<0.001), were significantly decreased after program, but changes of skeletal muscle mass, body fat mass were not significant. Resting heart rate (p<0.01), flexibility (p<0.001), whole body reaction (p<0.05), grip strength (p<0.01) and balance (p<0.01) showed positive changes after the intervention. Blood glucose level in serum was significantly decreased (p<0.001). These results indicated that dietary education and exercise program was effective not only for weight reduction but also for the improvement of physical fitness in obese adults.
