The purposes of this study were to investigate the effects of acute exercise on blood vaspin, glucose level, and inflammatory cytokines in middle-aged women with pre-diabetes. Nineteen middle-aged women (normal women, n = 11) and women with pre-diabetes(n = 8), who were apparently healthy and not taking any medications affecting their blood pressure or blood glucose, participated. Body fatness parameters including body mass index, body fat percentage, and waist circumference were measured using a bio-impedance analyzer. Resting blood pressure was measured in duplicate, and mean values were used for the data analysis. Regardless of group assignments, all subjects participated in a 3-day consecutive walking exercise at an intensity of 65% VO_2max targeting an energy expenditure of 1200 kcal (400 kcal per day). The major outcome variables included total cholesterol, triglycerides, high-density lipoprotein cholesterol, glucose, vaspin, interleukin-6, and adiponectin levels. Unlike normal women, women with pre-diabetes had a significant improvement in the homeostatic model assessment of insulin resistance (p < 0.025) with no significant group difference in response to acute exercise. The findings suggest that acute exercise results in a significant improvement in insulin sensitivity without any change in serum vaspin levels in women with pre-diabetes.

The UCPs are members of the mitochondrial inner membrane transporter family, present in the mitochondrial inner membrane. Their main function is increasing the energy expenditure via diminishing the resulting production of ATP from mitochondrial oxidative phosphorylation instead of yielding dissipative heat. They are associated with the metabolism of fat and regulation of energy expenditure. The UCP gene can be viewed as the candidate gene for chicken fatness. In the present study, RT-PCR and Northern Blot methods were developed to investigate the expression of the UCP gene in ten tissues including heart, liver, spleen, lung, kidney, gizzard, intestine, brain, breast muscle and abdominal fat of chicken. The results of both RT-PCR and Northern Blot methods showed that the UCP gene expressed specific in breast muscle. The expression levels of UCP gene in breast muscles from egg-type and meat-type chickens of hatching, 2, 4, 6 and 8 wk of age were detected by RT-PCR assay and results showed that the expression levels of UCP gene were related to breeds. Expression level of UCP gene in layers was higher than that in broilers at various weeks of age except at 6 wk. The UCP gene's expression was higher at 6 wk and had no significant difference among other weeks of age in broilers; in layers the expression level of UCP gene had no significant difference among weeks of age. The experiment results also showed that insulin could increase the expression level of UCP gene by 40% compared with control group.

Steers (n=335) of known genetic backgrounds from four fundamentally different growth types were subjected to two production systems to study differences in carcass traits. Growth types were animals with genetic potential for large mature weight-late maturing, intermediate mature weight-late maturing, intermediate mature weight-early maturing and small mature weight-early maturing. Each year, in a nine-year study, calves of each growth type were weaned and five steers of each growth type were developed on pasture or feedlot and slaughtered at approximately 20 and 14 months of age, respectively. Data collected were pre-slaughter shrunk body weight (SBW); hot carcass weight (HCW); dressing percentage (DRESS); fat thickness at the $12^{th}$ and $13^{th}$ rib interface (FAT); percentage kidney, pelvic, and heart fat (KPH); longissimus muscle area (LMA); marbling score (MARB); quality grade (QG); and yield grade (YG). Year and growth type were significant for all carcass traits. The growth type${\times}$production system interaction was an important source of variation in SBW, HCW; FAT, YG and MARB. The same interaction was non-significant for DRESS, KPH, LMA and QG. Carcass differences in measures of fatness were greater in the feedlot system than in the pasture system. These data could aid producers in matching beef growth type to the production system most suitable for efficient use of resources.

This study was performed to provide the dress form for high school girls' clothing construction which can reflect the characteristics of their body. Two hundred and forty seven high school girls aged from 15 In 17 were directly measured. The results obtained from this study were as follows ; 1. High school girls' somatotype was similar to that of young adult women. They had the features of well developed upper trunk and well developed breadth, but less developed depth. 2. The correlation between length item and the other items was small enough to interpret that each item was independent. There was a Positive correlation between depth item and girth item. And, Observed correlation between weight and Rohrer's index and breadth, depth and girth item was much larger than expected, which showed that weight and Rohrer's index influenced on fatness factor. 3. Through factor analysis, six factors were extracted from anthropometric measurements. The first factor was representing upper body volumn which expressed the characteristics of somatotype better than any other factors, the second factor was breadth, the third factor was size, the fourth factor was length, the fifth was back shape and the sixth factor was shoulder shape. 4. For development of dress form for high school girls, directly anthoropometric measurements were used. The dress form constructed through this study represented the characteristics of high school girls, therefore this would be very useful to manufacture clothing for them in the future.

Reproduction of the goby fish Periophthalmus magnuspinnatus was examined using 298 specimens collected from April to October 2005 in a mud flat of Suncheon Bay, Korea. Specimens ranged in body length(BL) from 1.3 to 9.1 cm. The gonadosomatic index(GSI) of females was highest in June and decreased until August. The hepatosomatic index(HSI) and fatness index of females were high in April and then decreased to nadirs in July. Spawning season lated from April to August and the ratio of females to males did not significantly differ($x^2$-test, p>0.05). The first spawning length was 4.5 cm BL, and the size of 50% maturity was estimated at 4.98 cm BL. Fecundity(F) ranged from 1,316 to 4,768 eggs, and the relationship between F and BL was estimated as $F=0.1562BL^{1.4068}(R^2=0.59)$.

This study helps out-size consumers purchase swimsuits and improves fitness by classifying the torso of middle-aged obese women; in addition, it creates a size system based on each size interval for obese types. The criteria for subjects in this study were over 25kg/$m^2$ of the BMI, over 85cm of waist, and over 95cm of bust; 199 females were surveyed. Three torso types were categorized by a cluster analysis into X type (the vertical size of hip girth was the biggest of the three and the waist was slender), H-O type (larger than other groups in bust girth with more fat above the circumstance of the abdomen), and Y type (the upper half of body development type and lower body fatness were between those of type X and those of type H-O). As a consequence of size system establishment according to obesity types, the basic body sizes and reference body sizes were different according to types even in commonly-appeared size names at sections of respective types. The research findings show the necessity to understand obesity types according to bust girth and hip girth sizes that represent basic sizes as well as to design patterns in consideration of the characteristics of obese body shapes when swimsuits are designed for obese groups. The findings can be used as basic data to decide the desirable output of production according to respective body types.

One hundred and twenty-eight finishing pigs (51.3 kg average initial body weight) were used to determine the effects of adding cellulase enzymes and lactobacillus acidophilus to sorghum-based diets on growth performance, carcass merit, and nutrient digestibility in finishing pigs. Treatments were: 1) corn-soybean meal-based positive control; 2) sorghum-soybean meal-based negative control; 3) Diet 2 with celluloytic enzymes; and 4) Diet 2 with a bacterial feed additive (lactobacillus acidophilus). There was a trend for greater average daily gain (ADG) in pigs fed com versus the sorghum treatments for day 0 to 28 (p < .09), but there was no effect of treatment (p > .15) on overall ADG (i.e., day 0 to 63). Feed consumption was not affected by treatment during the experiment (p > .19). Pigs fed the corn-soybean meal-based diet had 3.5% greater overall gain/feed than pigs fed the other diets (p < .009). Dressing percentage was not affected by treatment (p > .22), but there was a trend for backfat thickness at the last rib to be greater for pigs fed com versus the sorghum treatments (p < .09). Pigs fed the sorghum treatments had 1 % greater fat free lean index (p < .10) compared to pigs fed the corn-soybean meal-based positive control. Pigs fed com had greater apparent digestibilities of DM, N, and GE than pigs fed the sorghum treatments (p < .03), and greater DE intake (p < .07) suggesting that the increased carcass fatness for pigs fed the corn-based control diet resulted from greater energy status of those pigs. In conclusion, pigs fed the corn-soybean meal-based control diet had no improved growth performance but tended to be fatter than pigs fed sorghum. Adding cellulolytic enzymes or a bacterial feed additive to diets for finishing pigs did not affect growth performance, carcass merit, or nutrient utilization.

The effects of different rumen protected forms, oleamide, Ca oleate, of dietary oleic acid on the carcass quality and fatty acid composition in intramuscular and subcutaneous fat tissues of Hanwoo steer were examined. Sixty, 25 month old Hanwoo steers divided into three groups were fed no supplement (Control), 2% of oleamide (Oleamide) or Ca-oleate (Ca-Oleate) in their diet for 45 or 90 days. Disappearance rates of oleic acid supplements in digestive tracts (Rumen bypass, abomasal and intestinal disappearance rate) were 48.5, 68.4 for oleamide and Ca oleate, respectively. Both oleic acid supplements affected feed intake, growth rate, cold carcass weight and carcass fatness. Live weight gain, carcass weight, backfat thickness and marbling score were higher in the oleic acid supplemented steers compared with those from the control. Oleic acid supplements increased marbling score and ether extract in Hanwoo steer m. logissi thoracicmus. Rumen protected oleic acid increased not only the level of oleic acid but also polyunsaturated fatty acids in intramuscular and subcutaneous fat tissue. Total saturated fatty acid contents in both fat tissues were decreased whereas total unsaturated fatty acid content was increased compared with those from control. Linoleic acid, linolenic acid and polyunsaturated fatty acid contents were significantly higher in Ca oleate than any other steers. Lipid metabolites in blood were increased in rumen protected oleic acid treatments. HDL content in blood was increased in Ca-oleate supplemented steers whereas LDL was decreased compared with control. The changes of fatty acid compositions in the rumen protected oleic acid supplemented steers suggest that the oleic acid and unsaturated fatty acid were protected from rumen biohydrogenation and can be deposited in the fat tissues.

This study was intended to collect the baseline information on dietary behavior of adults to develop nutrition education program in the context of healthy weights at community level. Nutrient intakes of 128 housewives were assessed by 24 hour recall method. Also food habits, nutrition knowledge and attitude were investigated by self-administered questionnaires. Subjects were divided to under-weight, normal-weight, over-weight groups by body mass index (BMI). Most under-weight groups evaluated as their current body images were normal. $41\%$ of normal-weight groups judged as their current body images were obese. Energy and fat intakes of over-weight group were significantly higher than that of under-weight and normal weight groups (p<0.05). However, carbohydrate and protein intakes showed no significant differences among the three groups. It appeared that active attitude toward change in nutrition attitude of normal weight group was significantly higher than that of under-weight group (p<0.05). There were no significant differences of food habit score, nutrition knowledge, and obesity habit scores among the three groups. The frequency of eating-out showed significant difference among three groups (p<0.05). Food habit scores were positively related to health-concerned attitude (r=0.174), convenience-concerned attitude (r=0.229) and food enjoyed attitude (0.213) and negatively related to obesity habit score (r=-0.206). Also, positive correlation of body fat mass with frequency of eatingout (r=0.213), instant food (r=0.227) and amount of meal (r=0.187) existed (p<0.05). We concluded that nutrition education programs for housewives should include specific strategies to modify unsound food behaviors and inappropriate perception of body image for a healthy weight.

The effects of genetic, physiological, and environmental factors(temperature, and type of watering system) on growth factors, accumulation of abdominal fat(AF), and the association between growth factors and AF of broilers and Athens-Canadian Randombred (ACRB) were studied in a series of nine trials. The final BW(6 or 7 wk) and 4-6 or 5-7 wk gain (G) were greater in groups raised at 21.1˚C than 26.7˚C. There was no consistent effects of environmental temperature on feed conversion ratio (FCR) although the FCR was significantly (P$\leq$.o5) reduced in 21. 1˚C group compared with the 26.7˚C group in two of six trials. The overall mean weight of AF relative to BW at 43 or 50 days of age were not significantly different between temperature groups: the means of AF of 21.1˚C and 26.7˚C groups were 1.81 and 1.78%, respectively. Environmental temperature had no consistent effect on the relationship between 4-6 or 5-7 wk C and 43 or 50 days AF, and 4-6 wk FCR and 43-days AF ; however, the association of 50 days AF with 5-7 wk FCR was highly significant in both temperature groups. The overall mean of correlation coefficient between FCR and AF was very low (r=.107). The waterer types did not significantly affect the AF. Generally, the effect of sex on the relationship between G and AF was not consistent in both sex groups. However, the association of AF with G was much greater in ACRB group compared with broiler group. The initial body weights (4 or S wk) was significantly (P$\leq$.001) correlated with AF in ACRB group, but not in the broiler groups. The effect of sire on AF was very high(P$\leq$.0001) in five of six trials.
