Only the power is converted from AC to DC, in accordance with IEC 60587 based test method, in order to develop the LSR(Liquid Silicone Rubber) insulator material for HVDC, the experiment of Inclined Plate Tracking and Erosion Resistance was conducted. A contaminant (2.5 mS/cm: ammonium chloride) was applied at a rate of 0.3 ml/min and a voltage of ${\pm}3.5kV$, and was evaluated on the basis of 60 mA/2s. The samples were prepared by dispersing LSR/Nano silica_25wt% Composites in LSR. The erosion phenomena of surface discharge and tracking due to DC polarity and negative polarity were measured by image, leakage current maximum and thermal camera. The thermal imaging camera measured the surface temperature generated by the joule heat of the leakage current due to the drying discharge and the conductive current. After the measurement, the tracking and erosion mechanisms were evaluated for erosion weight, erosion depth and erosion length. Positive and negative polarity of LSR/Nano Silica_25wt% composite Tracking and erosion results show that positive polarity is more severe than negative polarity.

This study was performed to investigate the effectiveness of nutrition education and exercise intervention in a weight management program. The subjects were 24 obese women whose body mass index (BMI) was over $25kg/m^2$. Nutrition education was given once a week, and subjects did swimming three times a week. The program lasted for 12 weeks. Nutrient intakes were assessed by 24 hour recall method. Also food habits, dietary behavior and nutrition knowledge were examined by self-administered questionnaires before and after the weight control program. Height, weight, body composition and blood composition were measured before and after the weight control program. Over the 12 weeks in the weight control program, body weight significantly decreased from 69.7kg to 65.8kg(p<0.001). Body fat and BMI also significantly decreased(p<0.001). Cholesterol level significantly decreased at p<0.001 and blood sugar also significantly decreased (p<0.05). After taking nutrition education, dietary behavior and nutritional knowledge scores increased, energy intakes decreased from 1426.5kcal to 1408.5kcal and calcium from animal products significantly increased(p<0.05). A negative correlation between nutrition knowledge and BMI(r=-0.42) existed(p<0.05). A negative correlation of eating behavior with EER(r=-0.48) showed(p<0.05). We concluded that combined nutrition education and exercise was an optimal method for reducing weight.

Background: Little IS known about predictors of lifestyle modification in overweight or obese patients with acute myocardial infarctions. Methods: Between October 2005 and May 2007, 311 overweight or obese patients with an AMI visited Kyungpook National University Hospital. Among them, 216 patients ($63{\pm}11$ years old, 144 males) with ${\geq}1$ year of follow-up were included. Results: Body weight of all patients showed a significant decrease and 20% showed a >3% weight reduction at 1 year of follow-up. Ninety-six (44%) patients were smoking at baseline, and 52% of them had quit by 1 year of follow-up. Only six smokers were successful with both a >3% weight reduction and smoking cessation. In multivariate analysis, age (OR 1.084, 95% CI 1.028-1.144, p=0.003) and smoking cessation (OR 0.167, 95% CI 0.048-0.575, p=0.005) were independent predictors of weight reduction. Abdominal circumference was a negative predictor of smoking cessation (OR 0.903, 95% CI 0.820-0.994, p=0.037). Conclusions: Mean body weight of all patients showed a significant decrease at follow-up. Smoking cessation and age were independent predictors of weight reduction, and abdominal circumference was a negative predictor of smoking cessation.

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.

Herbal medicinal mushroom Cordyceps militaris has been traditionally used as tonic medicine for metabolic syndrome. Cordycepin, main extract of C. militaris, has been reported with immunomodulatory, anticancer, and hepatoprotective effects. This study was conducted to evaluate the potential hepatoprotective effect of cordycepin-enriched Cordyceps militaris, against high fat diet (HFD)-induced hepatic steatosis (HS) in male obese (ob/ob) mice. HFD was provided to ob/ob mice ad libitum (except negative control). Cordycepin-enriched C. militaris extract powder (CM) was orally administered once daily at dose levels of 0, 125, 250, and 500 mg·kg^-1 for 4 weeks. During the study, body weight gain was statistically increased in all HFD fed groups compared to negative control, but body weight gain in CM 500 mg·kg^-1 treated group shows a low tendency compared to HS model group. In organ weights, absolute and relative weights (to body weight) in liver and perirenal adipose tissue were increased in all HFD treated groups except CM 500 mg·kg^-1 treated group compared to the negative control. In clinical chemistry, serum glucose and total cholesterol levels in CM 250 and/or 500 mg·kg^-1 treated groups were lower than HS model group. In microscopical examination, hepatocyte vacuolation with macrovesicles in HS model group was increased compared to negative control, but this finding was decreased in CM 500 mg·kg^-1 treated group compared to HS model group. In this study, CM exhibited hepatoprotective effects against hepatic steatosis at mg·kg^-1 in ob/ob mice.

A 1-year-old, female Bengal tiger (Panthera tigris tigris) presented signs of weight loss and dark browncolored diarrhea. On fecal examination, numerous intact and broken red blood cells were found, but both parasites and inflammatory signs were absent. No significant findings were seen in serum biochemistry profiles, including electrolytes, with negative feline pancreatic lipase immunoreactivity (fPLI). Diagnostic kits using feces or peripheral blood were negative for feline parvovirus, feline coronavirus, feline immunodeficiency virus, and feline leukemia virus. Based on the result of feline trypsin-like immunoreactivity (fTLI) concentration ($4.6{\mu}g/L$), the tiger was provisionally diagnosed to have exocrine pancreatic insufficiency (EPI). After this diagnosis, pancreatic enzymes were prescribed. The feces of the tiger returned to normal form and her weight was increasing. EPI is uncommon and not described extensively in Felidae, including domestic cats. Feline EPI is associated with a variety of non-specific signs and it should be considered in the differential diagnosis of cases presenting with weight loss, diarrhea, and other gastrointestinal signs. In this case, the patient was strongly suspected to have EPI based on the very low fTLI concentration, though the concentration of fTLI in tigers has not yet been determined. This is the first report to present a suspected EPI case in Bengal tigers.

The purposes of this study were to investigate the relationships between appearance interest, appearance satisfaction, and life satisfaction of adolescent, to disclose the differences of these variables according to demographic characteristics, and to examine the determinants of life satisfaction. The subjects were 322 teenaged girls (167 middle school students and 155 high school students) living in Seoul. The variables of appearance interest were plastic surgery, weight control, clothing interest, and hairstyle interest. Life satisfaction included school life satisfaction and daily life satisfaction. Appearance satisfaction had negative relationships with plastic surgery interest and weight control interest, while appearance satisfaction had no relationships with clothing interest and hairstyle interest. School life satisfaction and daily life satisfaction had negative relationships with plastic surgery interest. The upper class adolescents had high level of clothing interest and life satisfaction, and lower class adolescents had high level of plastic surgery interest and had low appearance satisfaction as compared to other classes. The adolescent group with high school grade had high level of appearance satisfaction, and the group with low school grade had high level of weight control interest. The life satisfaction was influenced by appearance satisfaction the most, and the next in the order by school grade, residence area, and weight control interest. The explanatory power of the four variables was 30.8%. Social stratification and whether mothers had an occupation or not had an indirect effect on the life satisfaction.
