The purpose of this study was to investigate the dietary behaviors, eating habits, and nutrient intakes of elementary students with atopic dermatitis. Dietary conditions during infancy, dietary regularity, dietary behaviors, eating habits, and daily nutrient intakes were surveyed and compared between children with (WAD) and without (WOAD) atopic dermatitis using the 24-hr recall method. The ratio of children who responded 'I eat regular meals' was significantly lower in the WAD compared to WOAD group (76.4% vs. 81.7%, p<0.05). The ratio of children who answered 'I eat processed foods or fast foods more than once a week' (p<0.01) and 'I take nutritional supplements' (p<0.001) was significantly higher in the WAD compared to WOAD group. The scores for 'I eat milk and its products everyday' (1.4 vs. 1.5, p<0.05), 'I eat dishes fried or stirred with oil more than twice a week' (2.0 vs. 2.1, p<0.05), and 'I eat snacks such as ice cream, cake, snacks, carbonated beverages more than twice a week' (1.9 vs. 2.0, p<0.05) were significantly lower in the WAD group than in the WOAD group. Daily energy intakes were 1,859.1 kcal and 1,829.5 kcal in WAD and WOAD children, respectively, with no significant difference. However, daily intakes of fat (p<0.05), phosphorus (p<0.05), and vitamin $B_2$ (p<0.05) in WAD children were significantly higher than in WOAD children. To sum up, elementary students with atopic dermatitis had irregular eating habits and higher intake frequency of processed or fast foods, milk and its products, dishes fried or stirred with oil, and snacks compared to normal children. Dietary guidance and nutritional education are required to improve irregular eating habits and induce adequate nutrient intakes in children with atopic dermatitis.

The effects of feeding a mannan oligosaccharide (Bio-Mos) from 0 to 3 g/kg diet and vaccination program on 1- to 35-day performance (growth and feed efficiency), metabolizable energy, nitrogen utilization and carcass composition of meat chickens were investigated. A general vaccination program was used against IB, IBD and ND with half of the birds per diet receiving a booster dose of IB and ND vaccines at 12 days of age. Dietary supplementation of Bio-Mos (BM) did not influence body weight gain, feed efficiency and nutrient utilization. The highest dietary BM (3 versus 1.5 or 0 g/kg) increased carcass abdominal fat and reduced the proportion of drumstick in the carcass of meat chickens. The booster dose reduced the performance of birds. It was concluded that the addition of BM to the diet of chickens did not significantly influence the performance and nutrient utilization of meat chickens.

This study was designed to investigate and evaluate the dietary intake of 30 housewives, aged 35 to 59. The subjects kept daily diet records lot a period of one year. Their mean daily nutrient intakes met or exceeded the RDA (recommended dietary allowance) for all categories except energy, calcium, iron, vitamin A, and vitamin B$_2$. Mean daily calorie intakes were 81.2% of the RDA. The subjects received about 19% of their energy from fat and 15% from protein. Nutrient adequacy ratios (NAR) were 0.60 for calcium, 0.62 for iron, 0.71 for vitamin A, and 0.76 for vitamin B$_2$. The mean adequacy ratio (MAR) was 0.79. Subjects received various nutrients from rice, pork, eggs, and Kimchi. Rice was a major contribute. to many subjects' nutrient intake due to the high amount of consumption. Pork, rice, and vegetable oil greatly contributed to fat intakes while eggs, pork, and beef supplied a high level of cholesterol compared to other foods. Kimchi, anchovies, and milk were the major contributors of calcium, while rice, pork, and Kimchi were the major contributors of iron. These results indicate that the major nutritional problem of middle-aged housewives is an overall inadequate intake of energy, calcium, and iron.

An experiment was conducted to examine the effect of a high environmental temperature on the performance, conformation, and carcass characteristics of pigs and the influence of diet. Thirty-six three-way crossed castrated male pigs with average initial body weight of 50.4 kg were used in the experiment. The pig were allocated to the following treatments: two environmental temperatures (20 and $30^{\circ}C$)${\times}$three dietary energy levels (2,980, 3,300 and 3,600 kcal/kg)${\times}$three protein levels (12.8, 15.2 and 17.2%). Daily weight gain was lighter (p<0.01) and feed: gain ratio lower (p<0.05) in pigs at $30^{\circ}C$ than for pigs at $20^{\circ}C$ The pigs at $30^{\circ}C$ were significantly taller with deeper bodies (p<0.05) and significantly longer (p<0.05) both vertically horizontally in the planum nasal when kept at $30^{\circ}C$. The width of body and the circumference of the neck were greater (p<0.05) at $20^{\circ}C$. The lean meat of the loin, middle section, ham, and hind section were significantly greater (p<0.05) in pigs kept at $30^{\circ}C$ and the belly was significantly heavier. The total unsaturated free fatty acids were significantly higher (p<0.05) in the body fat of pigs kept at $20^{\circ}C$ than in that of pigs at $30^{\circ}C$. The results indicated that when pigs are given very restricted same amounts of feed, they may need less energy to maintain their body temperature under moderately high environmental temperature ($30^{\circ}C$); consequently, their performance is better than that of pigs under optimum environmental temperature. The results showed very clearly that weight gain of pigs increased with increasing of dietary protein and energy content. The increasing of dietary protein content seemed more significant when content increasing to 17.2% compared with the 12.8 and 15.2% protein content treatments. The increasing of dietary energy content was more significant when content increasing to 3,600 compared with the other low energy content treatments.

Dietary Variety Score (DVS) or Nutrient Adequacy Ratio (NAR) offers a way of comparing eating habits across populations and across countries. This study compared nutrients intakes, food intakes, DVS, and NAR between Korean and US adults using the large national survey data. 4662 Korean adults (men: 2201, women: 2461) aged 20-49 years were selected from the 'Korean National Health and Nutrition Survey,2001' and 4199 US adults (men: 2127, women: 2072) aged 20-49 years were selected from the 'US National Health and Nutrition Examination Survey (NHANES IV,1999-2002)'. The total plant food intakes were high in Korean adults, but the total animal food intakes were high in US adults. Intakes of legumes and nuts, vegetables and mushrooms were higher in Korean than in US adults. On the other hand, intakes of meats, milk and dairy products of US adults were higher than Korean. Beverage intakes were 8 - 10 times higher in US adults than in Korean. The mean DVS of Korean men and women were higher than US men and women. Intakes of fat, calcium and vitamin $B\_{2}$ of US adults were 1.5 - 2 times higher than those of Korean, which could probably related to larger consumption by US adults on milk and dairy product. While the intakes of carbohydrate and vitamin C of the Korean were higher than the US adults, which could presumably related to higher grain and vegetable consumption. Percent energy intakes from carbohydrate, protein, and fat were $64.1\%$, $15.8\%$, and $20.1\%$ for Korean men, $52.4\%$, $15.0\%$, and $32.6\%$ for US men, $65.9\%$, $14.9\%$, $19.2\%$ for Korean women, and $52.1\%$, $14.7\%$, $33.2\%$ for US women respectively, which showed higher $\%$energy from carbohydrate in Korean and higher $\%$energy from fat in US adults. Most nutrient intakes except energy and vitamin C expressed as $\%$RDA were higher in US than in Korean adults. Mean Adequacy Ratio (MAR) of US men and Korean men were both 0.85, while the MAR was 0.81 for Korean women,0.79 for US women. The Korean women's diet showed more diverse and adequate than the US women's diet.

This study was conducted to determine if supplementation with a compound composed of caffeine (50 mg), capsaicin (75 mg), sesamine (30 mg), L-carnitine (300 mg), banaba (50 mg) and lotus (10 mg) enhanced human autonomic nervous activities (ANS) associated with thermogenic sympathetic activity and fat utilization. Ten healthy college males (21.2$\pm$1.0 yr) volunteered for this experiment. Autonomic nervous activities associated with energy metabolism were examined at 30 min intervals for a total of 120-min while at rest and every 5-min during exercise at 50% of the ventilation threshold before and after intake of the compound or placebo with 100 ml of water for 10 days. In addition, heart rate variability power spectral analysis was used to assess human autonomic nervous activities. The results indicated that there were no significant differences in heart rate during rest and exercise among trials. Furthermore, the autonomic nervous activity tended to increase after 10-days of consumption of the test compounds during the experimental period, but the differences did not reach statistical significance. However, before and after the compound test trial there was a significantly higher respiratory gas exchange ratio (rest 0: 0.83$\pm$0.01 vs. rest 3: 0.89$\pm$0.02, p<0.05), carbohydrate oxidation (CHO) rate (rest 0: 44.57$\pm$5.83 vs. rest 2: 63.86$\pm$5.91%, p<0.05) and a lower fat oxidation rate (rest 0: 55.43$\pm$5.83 vs. rest 2: 36.14$\pm$5.91%, p<0.05. In conclusion, the results of the present study suggested that the compound composed of caffeine, capsaicin, sesamine, L-carnitine, banaba and lotus components that was evaluated in this study did not induce a significant increase in human autonomic nervous activities or lipolysis, even though the individual components have been reported to induce increased fat oxidation.

Two experiments were conducted to evaluate the use of various levels of full-fat sunflower seeds (FFSS) on broiler performance and carcass characteristics. In the first experiment, FFSS was included in a basal diet at 70, 140, and 210 g/kg and the $AME_n$ values of the experimental diets were determined. The linear regression equation of $AME_n$ values on rate of inclusion was calculated. Extrapolation value for the $AME_n$ of FFSS at 100% inclusion was 14.22 MJ/kg. In the second experiment, diets containing various levels (0, 70, 140, and 210 g/kg) of FFSS were given to broilers (Ross strain) from 0 to 49 d. At 28 days of age, blood parameters and digestive enzyme activities were determined and carcass parameters were evaluated at 49 days of age. Weight gain, feed intake and feed conversion ratio (FCR) were improved (p<0.05) when broilers were fed various levels of FFSS in the starter and finisher diets. Breast, thigh, gastrointestinal tract and gizzard weight percentages were not affected by dietary treatments; however, liver weight percentage was decreased significantly (p<0.05) and weight of abdominal fat decreased but this effect was not significant. The activities of digestive enzyme (protease and ${\alpha}$-amylase) were not influenced by the treatments. Activity of alkaline phosphatase, concentrations of calcium, phosphorus, glucose, triglyceride, protein, high density lipoprotein (HDL) and low density lipoprotein (LDL) were not affected by incorporation of FFSS in the broiler diet. Although concentration of HDL increased and LDL decreased, these effects were not significant. The results of this study indicate that FFSS can be used at up to 21% in broiler diets without adverse effects on performance or other parameters of chickens.

Purpose: The aim of this study was to analyze the association between sodium excretion and obesity for healthy adults in the Gwangju area. Methods: The participants included 80 healthy adults aged 19 to 69 years in Gwangju. The dietary intake and sodium excretion were obtained using the 24-hour recall method and 24 hour urine collection. The participants were classified into two groups according to the amount of urinary sodium excretion: (${\leq}141.75mmol/dL$, > 141.75 mmol/dL). Results: After adjusting for sex, age, smoking history, and income, the high excretion of sodium group was significantly higher for weight, body mass index, body fat mass, percent body fat, visceral fat area (VFA), waist circumference, hip circumference, and WHR. The energy and nutrients intake were significant after adjusting for sex, age, smoking history, and income. The LSE group had a significantly higher fat intake and Na/K intake ratio. The HSE group had significantly higher fiber intake, and K intake. As the amount of urinary sodium excretion increased, the risk of obesity before correction was 3.57 (95% CI: 1.13-11.25) times greater, and the risk of obesity of T3 increased significantly by 3.33 times (95% CI: 1.05-10.59). After correcting for sex and age, the obesity risk of T2 increased significantly by 4.23 times (95% CI: 1.11-16.06), and after correcting for sex, age, smoking history, and income, the obesity risk of T2 increased significantly by 6.81 times (95% CI: 1.44-32.19) the risk of obesity. Conclusions: An association exists between sodium excretion and obesity in Korean adults. In this study, the high excretion of sodium group was obese and the risk of obesity was higher than the low excretion of sodium group.

The present study was performed to evaluate energy and nutrients intakes of stroke patients in Daegu Gyeongbuk region, and to analyze the relative risk of stroke related to the intake levels of energy and nutrients. The case subjects (n=100) were selected from newly diagnosed stroke patients at Kyungpook National University Hospital. The control subjects (n=150) were selected from community residents who did not have stroke history and were sex and age-matched with the case subjects. The survey was conducted by individual interviews by trained dietitians using semiquantitative food frequency questionnaires. The odds ratios were calculated by using unconditional logistic regression. In male subjects, patient group had significantly higher consumption than the control group in mean daily intakes of energy, all energy yielding nutrients, vitamin $B_1$, $B_6$, niacin, folic acid, vitamin E, phosphorus, potassium, zinc and dietary fiber, and also in the ratio of energy intake from protein and fat. In women subjects, the patient group consumed significantly lower intakes than the control group in fat, vitamin C, folic acid, vitamin E, iron, but vice versa in carbohydrate energy ratio. As for men, the increased intakes of energy, protein, carbohydrate vitamin $B_1$, E and niacin, zinc, total fatty acids, monoand poly-unsaturated, n-6 fatty acids significantly raised the relative risk of stroke. As for women, the increased intakes of fat, vitamin A, $B_2$, $B_6$, niacin, vitamin C and E, iron, sodium, potassium, selenium, mono-, poly-unsaturated, n-6 fatty acids, cholesterol, taurine and dietary fiber significantly lowered the relative risk of stroke. The results of the study demonstrated that the effect of several nutrient intake levels, such as niacin, vitamin E and fatty acids, on the relative risk of stroke was inconsistent between sex. The reason for this sex difference needs to be elucidated in a larger scale study.

This study examined the effects of mulberry-leaf powder Tofu(MPT) on the anthropometric measurements, bone mineral density(BMD), biochemical markers of bone turnover, serum lipid levels of and macrominerals status in 30 female university students living in Choongnam with low dietary Ca intake was low(mean daily $intake=524.66{\pm}21.47$ mg/day). The subjects received the MPT supplemented(100 g/day) for 4 weeks. The nutrient content per 100 g MPT was 84.10 kcal(energy), 8.98 g(protein), 0.53 mg(fiber), 211.33 mg(Ca) and 1.59 g(fat). Anthropometric measurements, 24-hour dietary recall, carpus BMD using DEXA, select BMD biomarckers(serum alkaline phophatase activity, osteocalcin, urinary deoxypyridinoline), serum protein levels, albumin, and glucose levels, lipid profiles(cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol) and serum macrominerals(Ca, Ca/P ratio, Mg) were analyzed before and after MPT supplementation. Following MPT supplementation, there was no significant differences in anthropometric measurements, nutrient intakes, carpus BMD, serum alkaline phosphatase activity, osteocalcin, and urinary deoxypyridinoline, serum levels of protein, albumin, and glucose or lipid profiles with AI, HTR, LHR and CRF. However, there were significant increases in dietary calcium as well as decreases in serum triglycerides with MPT supplementation. Although further research is needed, these results that regular intake MPT could prevent bone and cardiovascular diseases.
