Adiponectin (AdipoN), brain-derived nerotrophic factor (BDNF) and leptin (LeP) are mainly secreted from adipose tissue and are known to be involved in regulation of the development of obese. However, there are not many studies on the association between abdominal fat and neuropeptides such as AdipoN, BDNF and LeP. The aim of this study was undertaken to investigate the association between abdominal fat thickness, neuropeptides and cardiovascular disease (CVD) risk factors. The participants in the study were 138 male employees without CVD. This study was approved by the Institutional Review Board of Occupational Safety and Health Research Institute. Written informed consent for the participants in this study was obtained from all individuals. We obtained subcutaneous fat thickness (SFT) and visceral fat thickness (VFT) by using ultrasonography and neuropeptides levels were measured with ELISA kit according to the method suggested by kit manufacturer. The mean SFT and VFT were $1.58{\pm}0.51$ and $4.52{\pm}1.44$ cm. The mean concentrations of AdipoN, BDNF and LeP were $3.14{\pm}3.52$ ng/ml, $24.11{\pm}8.52$ pg/ml and $4.27{\pm}2.38$ ng/ml, respectively. VFT were positively correlated with total cholesterol (r=0.217, p<0.05), LDL-cholesterol (r=0.271, p<0.01), triglyceride (r=0.233, p<0.05) and insulin (r=0.338, p<0.01), but was inversely correlated with HDL-cholesterol (r=-420, p<0.01). AdipoN levels were positively correlated with HDL-cholesterol (r=0.220, p<0.05) and were inversely correlated with total cholesterol (r=-0.196, p<0.05), LDL-cholesterol (r=-0.190, p<0.05), triglyceride (r=-0.199, p<0.05), SFT (r=-0.195, p<0.05) and VFT (r=-0.412, p<0.01). However, LeP levels showed a reverse trend to AdipoN. AdipoN level was significantly higher in non-obese participants (BMI<25 kg/m), but LeP concentration was significantly higher in obese participants (BMI>25 kg/m) than in non-obese. On multiple logistic regression analysis, obese were significantly associated with AdipoN (odds ratio=0.784) and LeP (odds ratio=1.494). These results suggested that AdipoN and LeP concentrations are affected abdominal fat and that dysfunction and/or declination in the production and secretion of neuropeptides might induced ultimately obese and CVD.

Thirty-six Naeimi ram lambs were equally and randomly allotted to four treatment groups with three replications per treatment to determine the simple and additive effects of monensin and zeranol on growth performance, carcass characteristics and nutrient digestibility. The treatment groups were: basal diet-fed lambs (C), monensin-fed lambs (M) where the basal diet was supplemented with 33 mg monensin per kilogram DM, lambs implanted with 12 mg zeranol (Z), and monensin-fed lambs implanted with zeranol (MZ). Lambs fed monensin-containing diet consumed 10.5% less (p<0.05) DM/100 kg weight and were 8.3% more (p<0.05) efficient in converting feed than lambs fed control diet. Zeranol implanted lambs tended to grow 35.2% (p<0.05) faster, consumed 5.1% more (p<0.05) feed and were (p<0.05) 21.9% more efficient in their feed conversion than control lambs. Responses of lambs to monensin and zeranol implants were not additive. Except for Z treatment, there were no marked differences in all carcass characteristics among the various treatment groups. Z-lambs produced 12.7% heavier (p<0.05) carcasses compared with those from C treatment. Also fat parameters, namely, kidney and pelvic fat (KP), body wall thickness and fat thickness, indicated trends for higher finish in Z treatment lambs (p<0.05) than for those lambs from other treatments. Except for CF and ADF, no significant differences in nutrients digestibility were noticed between various treatments; feeding monensin resulted in 24.5% and 8.5% depressions (p<0.05) in CF and ADF digestibility, respectively in comparison to C treatment. Nitrogen retention as percentage of total N-intakes was averaging 7.5 and 20.2% higher (p<0.05) in lambs implanted with zeranol than those fed the M and C diets, respectively.

Purpose: This study aimed to identify the effects of myofascial pain syndrome on shoulder pain, range of motion, and body composition around the shoulder in middle-aged women. Methods: A total of 72 women participated in the randomized controlled trial. The subjects were grouped into an experimental group (n=39) and a control group (n=33). The experimental group received a resistance exercise program using an elastic band for 8 weeks, 3 days a week. The control group followed a normal daily for 8 weeks. Measurements were conducted three times; before the experimental treatment (pre-test), the 2nd and 8th weeks after treatment. Results: Regarding the general characteristics and homogeneity of the dependent variables, there were no significant differences between the two groups, except for the thickness of the left and right muscles and the left fat. After treatment, shoulder pain was significantly different between the two groups (F=18.54, p<.001) and the range of shoulder motion was significantly different (left, F=86.70, p<.001; right, F=98.66, p<.001). Furthermore, there were a significant differences in the thickness of muscles between the two groups (left, F=40.20, p<.001; right, F=29.57, p<.001); however, the thickness of fat was not significantly different. Conclusion: The resistance exercise program reduces shoulder pain and improves the range of motion of the shoulder joint and increases muscle mass on around the shoulder. It suggests to conduct a study to confirm the long-term exercise effect.

To investigate the effects of exercise-training on serum lipids, fat distribution and several parameters of body fatness(percent body fat, skinfolds thickness, body circumference) were assessed in 24 healthy male subjects submitted to an 8-wk high intensive exercise-training. Blood sample was taken twice, per and post exercise-training, Exercise-training took place 5 days a week and daily energy intake and expenditure were observed. The results obtained are summarized as follows: 1) Through exercise-training body weight (changes : 1.1$\pm$1.1kg ; p=0.000) and percent body fat (changes : 2.4$\pm$1.3% ; p=0.000) decreased significantly . 2) Suprailiac was the most reduced site by exercise-training among eight site skinfolds. Central skinfolds were changed more by exercise-training than peripheral skinfolds with reduction of 1.7$\pm$1.7mm and 0.2$\pm$1.9mm. Central site circumferences were reduced more by exercise-training than peripheral site circumferences. 3) Total cholesterol, HDL-cholesterol and LDL-cholesterol were not significantly changed by exercise-training while only triglyceride decreased (changes : 20.7$\pm$44.8mg/dl ; p<0.05). Changes in body weight were grately related to changes in total cholesterol. Changes in deep abdominal adipose tissue were related to changes in triglyceride.

This study was designed to investigate the effects of 8-week resistance exercise by using dumbell on the body com-position, serum hormone profiles and feeding patterns in young and healthy female students with over 30% of body fat, aged 22 years in Masan, Korea. The subjects were all six, performed successfully the entire exercise-program. Anthropometry, serum lipid and neurohormone profiles of subjects were analyzed at 0, 4 and 8 weeks after exercise. And also their food and nutrient intakes were self-reported by 3-day record and food frequency questionnaire. Triceps skinfold-thickness of the subject students significantly reduced after the exercise to 46% less than before (p < 0.002) . The serum concentrations of leptin, insulin and catecholamine appeared to decrease steadily, but not significantly. Total protein in serum increased significantly (p<0.05), and Na (p<0.005), K (p<0.001) and Fe (p<0.058) concentrations increased remarkably within the normal range. The 8-week resistance exercise tended to induce fiber consumption (p<0.089) of subject students and changed the P/M/S ratio changed into the desirable way from 0.8 : 1 : 1 to 1 : 1 : 1, and that of n-6/n-3 PUPA from 11 : 1 to 6 : 1. After taking exercise, the intake frequency of cookies (p<0.058) and raymeun (p<0.085) decreased, but finally this feeding pattern returned to the way as before even though at marginal significance. Consequently the resistance exercise may induce the desirable changes of body fat and improve serum lipid profiles and feeding patterns in young obese females.

Objective: This study was conducted to evaluate the correlation between body size traits, carcass traits, and primal cuts in Hanwoo steers. Methods: Sixty-one beef carcasses were classified for conformation and primal cut weight. Additionally, carcass weight, fat thickness, carcass dimensions, and longissimus muscle area were determined to complement the grading. Results: The average live weight and cold carcass weight were 759 and 469 kg, respectively. The mean carcass meat, fat, and bone proportions were 551, 298, and 151 g/kg, respectively. Primal cuts weights showed significant positive correlations (p<0.001) of 0.42 to 0.82 with live weight, carcass weight, and longissimus muscle area and a significant negative correlation with carcass fat (without shank, -0.38 to -0.10). Primal cut weights were positively correlated (p<0.01) with carcass length (0.41 to 0.77), forequarter length (0.33 to 0.57), 6th lumbar vertebrae-heel length (0.33 to 0.59), 7th cervical vertebrae carcass breadth (0.35 to 0.58), 5th to 6th thoracic vertebrae breadth (0.36 to 0.65), 7th to 8th thoracic vertebrae girth (0.38 to 0.63), and coxae girth (0.34 to 0.56) and non-significantly related to cervical vertebrae length and coxae thickness. Conclusion: There was a high correlation among live weight, carcass weight, longissimus muscle area, carcass length, 7th cervical vertebrae carcass breadth, 5th to 6th thoracic vertebrae breadth, and 7th to 8th thoracic vertebrae girth of the primal cuts yield. The correlation between fat and primal cut yields was highly significant and negative. Carcass length and 7th to 8th thoracic vertebrae girth, appear to be the most important traits affecting primal cut yields.

The current study was conducted to evaluate carcass characteristics, objectives and sensory meat qualities of Hanwoo longissimus muscle as affected by ultimate pH. Twenty-four steers and bulls ($556{\pm}53$ kg and $0.63{\pm}0.32$cm for live weight and backfat thickness, respectively) were used. As there was a linear relationship (r = 0.77) between lean meat color and ultimate pH, cattles were thus segregated into normal $pH{\leq}5.8$, Normal, n = 13) and DFD (pH>5.8, n = 11) groups. Normal pH group had significantly (p<0.05) higher carcass weight, marbling score and backfat thickness than those for high pH group, while fat color and lean meat color were inverse. In principle component analysis for co-ordinates of DFD and normal meats, fat color, lean meat color, texture, time to pH 6.2 and pH at 24 h postmortem were associated with the positive range of the first factor (67.5%) while backfat thickness marbling score and temperature at 24 h were placed in negative values. The rate constant of decline in pH (pH k) did not differ between the two groups, implying that initial pH (i.e., pH at slaughtering) differed between two groups. Contour mapping of pH k between pH at 1 and 24 h postmortem indicated that high pH k was related to lower pHs at 1 and 24 h postmortem. This suggested that the high pH cattles (i.e., DFD cattle) resulted from their own potential. Although the time to reach pH 6.2 was significantly (p<0.05) shorter for normal meat (i.e., 3.2 h) than that for DFD one (i.e., 19.8 h), there were no significantly differences in both WB-shear force and sensory attributes. Given that the experimental animals were sampled from a similar group, which implies a similar myoglobin pigment content, the current data suggested that pre- and post-slaughter animal handling likely had a significant effect on ultimate pH and consequently meat color of Hanwoo longissimus muscle, and also small animals with lower marbling score and backfat thickness had a higher risk for DFD meat.

Anthropometric and body compositional changes and the outcomes of the pregnancies of 90 healthy Korean women were investigated in a longitudinal study. Their weight increased from 51.3$\pm$5.9kg to 65.1$\pm$7.8kg during their pregnancies. The total weight gain was 13.8$\pm$4.5kg, and therefore, weekly weight gain was 340$\pm$110g during the entire period of the pregnancy. The weight gain was composed of approximately 50-60% fat mass and 40-50% fat-free mass. Skinfold thicknesses, both of triceps and subscapular, increased during the pregnancies. The fat mass calculated from skinfold thickness and that measured with bioelectrical impedance analysis went on increasing during the pregnancies. Although there was a considerable difference with respect to the fat mass observed using the three methods, fat mass gain was 5.0-6.1kg and fat-free mass gain was 4.0-5.3kg from the first trimester to the third trimester of pregnancies. There were significant correlations between maternal anthropometric parameters and indices of pregnancy outcomes. Especially, the infant's birth weight was associated with maternal pre-pregnancy weight and weight gains during the pregnancies. The infant's birth length was related to the maternal weight observed at term(p<0.05) and weight gain during the entire pregnancies (p<0.05) . Neither increase of fat mass nor fat-free mass affected the outcomes of pregnancy. These results show that maternal weight gain during pregnancy is led by increments of approximately above 50% fat mass. The fat mass increase seems to be larger in central areas than in subcutaneous areas. Maternal weight gain during pregnancy, especially during late pregnancy, is a factor affecting the birth weight and length of infant. On the basis of the body compositional changes, it can be predicted that the additional energy requirement for pregnancy in Korean women is more than 200-230 MJ (64,500-76,250kca1).

This study analyzed the effects of pH, sex, backfat thickness, ribeye area, cold carcass weight, shipping month, muscle internal temperature, average daily temperature, and average relative humidity for slaughtered Hanwoo to meat color by season. The analyses focused on interaction and each effect to meat color of the factors. For the result for analysis of multiple linear regressions, meat color values were decreased as pH increased in all meat color, and the meat color values increased as the backfat thickness was increased. As the results of the decision tree analysis by each factor, cow and steer slaughtered in spring and autumn were the highest in the lightness(L*). The redness(a*) was the cases that pH was less than 5.63 and average relative humidity was over than 71.5% for Hanwoo slaughtered in autumn. The chroma(C*) value was the highest for Hanwoo that was slaughtered in summer and autumn, the pH was less than 5.60, and the back fat thickness was over than 8 mm. The hue angle($h^0$) was shown that the muscle internal temperature was less than 4.7$^{\circ}C$ among Hanwoo which was slaughtered in spring, summer, and autumn, the pH was less than 5.66, and the back fat thickness was over than 8 mm.

The purpose of this paper it to investigate the differences in prevalence of obesity and body fat distribution on the variances of age. Height, weight, skinfold thickness and girth circumference on about 422 women residing in Cheju, Korea were surveyed. The results of analysis of the survey are as follows : 1) All the antropometric measurements except height were shown to increase with age. Weight is at its highest level between the age of 50-59. The measurement of skinfold thickness and girth circumference between the ages of 20-39 of the female subjects are significantly higher than the above 40's. However, there is no significant difference among the middle aged women. 2) Physical indices tend to increase according to age. Both BMI and RBW of women in their 50's are at their highest values, however, the index values of the women in their 60's decreased slightly (p<0.05). On the contrary, there is no significant difference in the percentage of body fat and total body fat content among the middle aged women surveyed. 3) According to this survey, 15.6% of the 422 subjects are assessed as being obese ; more specifically 4.4% of women in their 20's, 12.6% in 30's, 25.6% in 40's, 22.5% in 50's and 17.3% in 60's. 4) 39.4% among obese women proved to be upper body type women. Because the frequency of upper body type women became higher as the obese women aged, there is possibility that the pattern of fat distribution can change. 5) Weight is the most highly correlated with BMI(r=0.91), whereas weight as correlated with RBW, percentage of BF and WHR are 0.8, 0.66 and 0.44 respectfully. The conclusion of this survey is that it is better to estimate the value of total body fat and percentage of body fat than the value of BMI in the analysis of prevalence of obesity and its related factors of middle aged women.
