The purpose of this study was to investigate the dietary related factors and blood parameters of moderately or severely obese children residing in Samcheok. Anthropometric measurement, 24-hour recall for dietary intake, blood analysis and questionnaire response including nutritional knowledge, nutritional attitude, body image recognition and eating habits were conducted in 23 obese children(16 boys and 7 girls) and their mother. The mean age of subjects are 10.0 years. The average body weight, BMI, obesity index and percent body fat were 57.5㎏, 27.0㎏/$m^2$, 47.3 and 38.1% in boys and 51.0㎏, 24.8㎏/$m^2$, 40.3 and 43.9% in girls. The average nutritional attitude, the self-satisfaction and the nutritional knowledge scores in subjects were 29.9/40, 32.7/50 and 7.3/10, respectively. 34.8% of the subjects were unsatisfied with their body image, whereas, 81.8% of their mothers were unsatisfied with children’s body image. 60.9% of subjects had one or both obese parents. Average intake of energy were 90.6% of RDA in boys and 84.3% of RDA in girls. The ratio of energy from carbohydrate/protein/fat were 66/16/18 in boys and 66/17/17 in girls. The mean serum cholesterol concentration of the subjects was 191.8mg/dl and 78.3% of the subjects were above the normal serum cholesterol rage of children. In the results of correlation analysis, obesity index was negatively correlated with self and mother’s nutritional attitude scores. Body weight and BMI were positively correlated with vitamin C(p<0.05) and fruits(p<0.05) intakes. And there was a positive correlation between obesity index and BMI, and serum cholesterol(p<0.05).

The purpose of this study was to examine the convergence correlation between physical characteristics and functional movement screen(FMS). Overall, 193 adults with normal single measurement values participated in the study. For data analysis, we used the SPSS Ver. 26.0 statistical program to perform t-tests and to determine Pearson's correlation coefficients for variables. Data analysis revealed significant sex differences in the active straight-leg raise and trunk stability push up tests (P<.05). In addition, our data analysis also revealed a negatively correlation between body fat percentage and FMS tests, except in the shoulder mobility and active straight leg raise test. In the active straight leg raise, the quality of functional movement was higher in women than in men; while in the trunk stability push ups, the quality of functional movement was higher in men than in women. Therefore, we conclude that men should reinforce the flexibility of the lower extremities, and females should apply upper body muscular strength for better trunk stability movement.

24-hour recall is the dietary assessment method most frequently used to evaluate dietary intake; however, accuracy is an issue when using this method, especially in large-scale studies. The purpose of this study was to assess the validity of dietary intake estimation using one serving size. Estimates of energy and nutrients taken in over a 24-hr period based on actual intake amount (24HRAI) and based on estimates of one serving size (24HRSS) were compared. Data were analyzed using a paired t-test, Pearson's correlation coefficients, and a cross-classification method. In male subjects, intake levels of energy, fat, vitamin C, vitamin $B_1$, Zn, and total food measured using 24HRAI were significantly higher than those measured using 24HRSS. In female subjects, intake of carbohydrates, fiber, fat, vitamin A, vitamin C, vitamin B complexes, various minerals, and total food measured using 24HRAI were significantly lower than those measured using 24HRSS. Energy-adjusted Pearson's correlation coefficients revealed that intake of all nutrients showed a significant positive relationship between the two measurement methods in both males and females. Cross-classification analysis revealed that 50.5~67.6% of women and 40.3~71% of men were classified in the same quartile of intake of each nutrient when comparing data from 24HRAI and 24HRSS. We conclude that using one serving size in 24-hr recall analysis was valid and therefore may be used in studies to assess food consumption in the general adult population. Also, this method can be used to classify energy and nutrient intake into quartile, which is useful in examining the association between diet and chronic diseases.

A 4-week energy balance study was conducted to estimate the energy expenditure (EE) of 7 high school age girl, 15 to 16 year age, by measurement of energy intakes and changes in body energy (BE) content (intake/balance technique), keeping their normal living pattern and eating behavior. Gross energy intake (GE) and fecal energy (FE) loss was measured by bomb calorimetry. Urinary energy (UE) loss was calculated from nitrogen excreted. Fat mass (FM) was determined from body density estimated from skinfold thickness. Mean constitutional ratio of carbohydrate, protein and fat for the total energy intake was 70.1$\pm$1.8%, 12.2$\pm$0.7% and 17.7$\pm$2.0%, respectively, Fecal energy loss was 2.8% proportion of the gross energy intake. Mean daily metabolizable energy estimated by subtract fecal and urinary energy loss was 2022 $\pm$ 50㎉. Total body energy change estimated from body composition change over 28days was increased 2400 $\pm$ 950㎉ . Mean daily energy expenditure was 1958$\pm$87㎉ (39$\pm$2㎉ /kg of body weight).

The purpose of this study was to investigate the effect of nutritional status on the cell-mediated and humoral immunity in female college students. The nutritional status of twenty subjects was determined by six-days food records, anthropometric measurements, and biochemical assessments of serum nutrients. Cell-mediated and humoral immunity of the subjects was analyzed by in vivo and in vitro assessments. The results were summerized as follows : First, The average daily energy intake was 1437Kcal(CHO : PRO : FAT = 61:13:26), which corresponds to 71.9% of RDA. Anthropometric measurements showed that 50% of the subjects was under-weight(BMI<20), only 5% was over-weight(25

This study was aimed at evaluating the nutritional status of Korean lactating women, who were attending peripheral community clinics in low-income areas, by anthropometric measurement, estimating dietary intakes and analyzing the contents of breast milk components, serum lipid content and fatty acid composition. Regarding anghropometric measurements, maternal circumferences decreased significantly at the trunk but not at the limbs. The skinfold thickness on all regions had the tendency to decrease during lactation. It was found that intakes of energy, protein, lipid and carbohydrates were desirable while calcium, zinc, copper and vitamin A were low and sodium was excessive. The energy $\%$of fat was 22.41$\%$of the total energy which is higher than the RDA for adults but it is proper for lactating women, but energy $\%$ from each fatty acid was usually low and an intake ratio of $\omega$6/$\omega$3 fatty acids was desirable. Accordingly, it is thought that dietary fat intake was balanced in quality. Concentrations of the nutrients in matured human milk showed the same range as that reported form different regions with the exception of calcium and magnesium which were relatively low. Serum lipid contents were decreased with the time postpartum and the average serum lipid content of lactating women were similar to the normal range of adults. Serum polyunsaturated fatty acids. especially $\omega$6 fatty acids have gradually increased with the time postpartum, but the composition were not greatly influenced by dietary intakes.

This study was carried out to make early prediction of carcass yield grade. Sixty six Hanwoo steers were measured for back fat thickness, longissimus muscle area and body weight at 18, 21 and 24 months of age by ultrasound. Carcass evaluation was done after ultrasound measurement at 24 month of age. Ultrasonic yield grade at 18, 21 and 24 month of age were predicted by regression and decision tree methods. Classifying by carcass yield grade, ultrasonic back fat thickness at 18, 21 and 24 months of age was significantly different in each carcass yield grade (p<0.05). The prediction accuracy of carcass yield grade by regression method was 78.8% at 18 months, 86.4% at 21 months and 90.9% at 24 months of age. By using the decision tree method for carcass yield grade, 78.8%, 89.4% and 89.4% of prediction accuracy were obtained at 18, 21 and 24 months of age, respectively.

The effects of feeding of diets based on roughage supplemented with concentrate on the carcass and meat quality attributes of Korean black goats were investigated. The 40 male goats at 5 mon age were divided into four treatment groups; T1 (1.5%), T2 (2.0%), T3 (2.5%) and T4 (ad libitum) feeding of concentrate with ad libitum rice straw. Forty bucks at the end of the feeding were fasted for 12 h before slaughter and were then slaughtered. For carcass measurement, cold buck carcasses were examined after 24 h of chilling at $5^{\circ}C$. The carcasses were chilled in refrigerator at $2{\pm}2^{\circ}C$ for 24 h, then the longissimus dorsi muscle was removed from the carcasses. The samples were separately vacuum packaged, frozen and stored at $-20^{\circ}C$ for up to 1 mon, prior to physicochemical evaluations. Carcass yields were greatly affected by rate of concentrate feeding. T4 showed the heaviest live and carcass weights and the highest dressing and fat percentages (p<0.05). The moisture contents were lower in T4 compared with other treatments, while the crude protein and fat contents were higher (p<0.05). mono-unsaturated fatty acid in T4 was significantly higher than others, which showed the highest percentages of oleic acid (C18:1). For the sensory test, T4 was tenderer and produced better flavor scores than others. Increasing the level of concentrate in the diet resulted in an improvement in growth performance, and carcass and physicochemical characteristics of goat meats.

Background: The relationship between obesity and prostate cancer aggressiveness is controversial in recent studies, partly because BMI is the only generally applied marker of obesity. Our study aimed at evaluating the correlation of periprostatic fat (PF) on magnatic resonance imaging (MRI) and adipocytokines with prostate cancer aggressiveness. Patients and method: A total of 184 patients who underwent radical retropubic prostatectomy (RRP) were analyzed retrospectively; different fat measurements on MRI slices and levels of adipocytokines were compared with the clinical and pathologic factors using SSPS ver.13.0. Result: The PF rates showed a statistically significant variation (p=0.019, 0.025) among groups, that is to say, more adipose tissue was distributed in periprostatic areas of high risk patients. Logistic regression analysis adjusted for age revealed a statistically association between the PF, the ratio and the risk of having high-risk disease (p=0.031, 0.024). The levels of IL-6, leptin and c-reactive protein (CRP) significantly increased with the aggressiveness of prostate cancer, and also with PF and its ratio. The strongest correlation was seen between IL-6 and PF (Pearson r coefficient=0.67, P<0.001). No association was observed between adipocytokines and BMI. Conclusion: Periprostatic adiposity not only affects prostate cancer aggressiveness, but also influences the secretion of adipocytokines. IL-6, PF and CRP have promoting effects on progression of prostate cancer.
