Two experiments were conducted to investigate the effect of feeding cyanidin 3-glucoside (C3G) high black rice bran on nutrient digestibility, blood measurements, growth performance and pork quality of pigs. In Exp. I, a total of fifteen pigs (19.91${\pm}$1.80 kg, average initial body weight) were used in assay of nutrient digestibility and blood measurements. All pigs were allotted to 5 treatments with 3 replicates according to a completely randomized design (CRD) in an individual metabolic crate. Treatments included 1) CON: basal diet, 2) BRB-2: basal+brown rice bran 2%, 3) BRB-4: basal+brown rice bran 4%, 4) CRB-2: basal+C3G high black rice bran 2% and 5) CRB-4: basal+C3G high black rice bran 4%. The digestibility of dry matter (DM), crude protein (CP), crude fat (CF), crude ash (CA) and crude fiber (CF) was not affected by dietary treatments. Serum triglyceride (TG) and high density lipoprotein (HDL) cholesterol concentrations were not affected by addition of C3G high black rice bran. However, at the end of experiment, pigs fed rice bran showed decreased tendency in total cholesterol concentration. Especially pigs fed C3G high black rice bran showed significantly lower total cholesterol concentration compared to pigs fed brown rice bran (p<0.03). There was numerically lower total cholesterol concentration with increasing levels of black rice bran in the diet. In terms of serum glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT), there were no significant differences among treatments, even though pigs fed CRB-4 showed the lowest GOT concentration compared to other pigs. In Exp. II, sixteen finishing pigs (average initial body weight 89.96${\pm}$0.35 kg) were divided into 4 treatments to investigate the effect of feeding C3G high black rice bran on growth performance and pork quality. There were no significant differences in average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) among the treatments. Pigs fed C3G high black rice bran showed numerical decrease in ADG and increase in FCR while not effecting feed intake. There was no significant difference in live weight, carcass weight, carcass rate, backfat thickness and carcass grade. However, pigs fed C3G high black rice bran tended to show lower backfat thickness than pigs fed basal diet. Pigs fed C3G high black rice bran showed a tendency of decreased TBA value than pigs fed basal diet, although there was no overall significant difference among treatments. In conclusion, nutrient digestibility, blood measurements, growth performance and pork quality were not significantly affected by feeding C3G high black rice bran to pigs. However, C3G high black rice bran might have an effect on lowering serum total cholesterol and decrease the TBA value in pork compared to control group and these effects might be due to high concentration of antioxidative compounds in C3G high black rice bran.

This experiment was carried out to investigate the effects of Zeolite levels on the performance of broilers. 360 starting chicken of Arbor Acre were selected for this study. Chickens were fed 4 levels (0.2.4 and 6％) of Zeolite in the basal ration for 7 weeks. The results obtained were as follows: 1. The body weight gain was highest in the 2％ supplement of Zeolite, but more than 4％ supplement resulted in lower body weight gain (P<0.05). 2. No significant differences were found in the feed intake among the treatments. 3. Feed conversion had no significant differences, among treatments but 6％ Zeolite group was slightly higher than the others. 4. The viabilities were not significantly differences among the experimental groups. 5. Moisture in excreta was tend to be decreased significantly as Zeolite levels were increased (p<0.01) 6. Carcass yield and abdominal fat deposition were not different significantly over all experimental groups. 7. Highest income was attained by 2％ supplement of Zeolite, but 6％ group was reduced significantly (P<0.05).

The purpose of this study was to determine the health behaviors and nutritional status related to dyslipidemia in Korean middle-aged adults (between 50 and 64 years old) from the Korean National Health and Nutrition Examinations Survey data (2007~2010). A total of 4,721 subjects were analyzed in this study. The subjects were divided into three groups (normal, borderline, and dyslipidemia) according to serum lipid levels. Parameters included in this study were drinking and smoking, anthropometric parameters, blood and nutritional parameters. The latter parameter included food/nutrients intake. All data was adjusted by sex, region, education level, and age. General linear model and logistic regression model were used for statistical analysis. The dyslipidemia group was comprised of more men than women. By contrast, the borderline group was comprised of more women than men (p<0.001). No significant differences were observed for other general characteristics. There were more smokers and drinkers(drinking per time) in the dyslipidemia group (p<0.05). Anthropometric data showed significant difference, ie, height (p<0.05), weight, body mass index, waist circumference, percent body fat, and blood pressure were higher in the dyslipidemia group (p<0.001). Only blood urea nitrogen showed no significant difference among groups. The HbA1c (p<0.01), fasting blood glucose, GOT, GPT, creatinine levels were higher in the dyslipidemia group (p<0.001). So it is required for the management of obesity in dyslipidemia group. The dyslipidemia group ate less sea food (p<0.05). The nutrients intake of energy and protein, thiamin, riboflavin, niacin, calcium, phosphorus were lower in the dyslipidemia group (p<0.05). Therefore, to lower dyslipidemia prevalence rates, it is necessary to increase the intake of foods containing ${\omega}-3$ fatty acids. We also suggest a meal management program and nutritional education to recognize the risk of dyslipidemia, especially for people such as the individual in the borderline and dyslipidemia study groups.

We investigated the effects of dietary supplements of probiotics, illite, active carbon and hardwood vinegar on growth performance, carcass characteristics and fatty acid composition in finishing pigs. One hundred fifty pigs ($Landrace{\times}Yorkshire{\times}Duroc$; $32.3{\pm}1.3 kg$ average initial body weight) were used in a 100 day experiment. Pigs were randomly placed into five experimental feeding groups (control, 0.2% probiotics, 1.0% illite, 1.0% active carbon and 1.0% hardwood vinegar) and were slaughtered at approximately 110 kg live weight. There was a slight, but insignificant increase in average daily body weight gain and feed intake among all treatment groups. Feed conversion was reduced when probiotics were added (p<0.05). There were no significant differences in the carcass rate and back fat thickness among the all treatment groups including controls. However, the frequency rate of grade A increased in the groups fed 1.0% active carbon and hard- wood vinegar compared to controls. Stearic acid content was lower in the groups fed probiotics illite active carbon and hardwood vinegar (p<0.05). Oleic acid contents were higher only in the groups fed 1.0% active carbon and hardwood vinegar (p<0.05).

The human adipose and milk samples analyzed in this study were collected at hospitals in Seoul, Masan and Jinju. The mean values of International Dioxin Toxic Equivalents (I-TEQ) of PCDDs and PCDFs in human adipose samples from the three regions were calculated as 9 pg I-TEQ/g(0.2 ~ 30 pg TEQ/g, lipid weight basis) and 8 pg I-TEQ/g (0.8 ~ 25 pg TEQ/g), respectively. The residue levels of PCDDs-TEQ and PCDFs-TEQ in human milk collected from Masan were 13 pg I-TEQ/g (lipid wt.) and 4.8 pg I-TEQ/g, respectively. On the whole, the contamination levels of these compounds in the Korean population were lower than those in the other countries. Based on the analytical data and assuming a daily intake consumption of 800 mL milk with 3% fat, the average daily intake of PCDDs/DFs via human milk for a baby weighing 5 Kg could be calculated. The daily intake of PCDDs/DFs via breast-feeding was estimated to be 39 pg/kg body weight/day for 2,3,7,8-TeCDD and 86 pg/kg/day for TEQ. These levels are far above all virtually safe dose(VSD) or tolerable daily intake(TDI) values proposed by health authorities in various countries, ranging from 0.001(US EPA) to 4 pg/kag/day (WHO).

The purpose of this study was to investigate the changes of long term ECG response in a company with middle-aged male employees. Subjects were 60 men who were 40~55 years old. We enrolled 30 exercise group subjects into a 3-year exercise program. In measurement index, body composition was measured by % body fat and BMI. Exercise stress test analyses were measured using ST/HR slope and QRS vector. Statistical analysis was performed using analysis of repeated ANOVA. Results of this study were as follows: In ST/HR slope, the control group showed symptoms of ischemia after nine minutes of exercise. In the rest frontal axis of the QRS vector, the control group had a tendency towards right axis deviation. In the rest horizontal amplitude of the QRS vector, the control group had a tendency to show a significant decrease, but it was increased significantly in the exercise group. These findings suggest that inactive company workers was showed a decrease of exercise capacity, early diagnosis exercise-induced ST depression, and prolonged deviation of QRS vector, but that cardiac function could be elevated in active middle aged men through regular exercise program participation.

The effect of stocking density on the growth and meat quality of native Korean chickens was investigated. A total of 364 one-day-old native Korean chickens were randomly assigned to one of 5 treatments, each of which was replicated 4 times. Five distinct stocking densities-14, 15, 16, 18, and 22 birds/㎡-were compared. The diet was fed ad libitum for 10 weeks. Results indicated that the final body weight, body weight gain, and feed intake were lower (P<0.05) for the 22 birds/㎡ stock density as compared to the other stock densities. There was no significant difference in the feed conversion ratio, proximate analysis (DM, crude protein, crude fat, and crude ash), water-holding capacity, and cooking loss among the different stock densities. These results indicate that increasing the stock density to 22 birds/㎡ elicits some negative effects on the growth performance and meat quality of Korean-native chickens.

The aim of this study was to evaluation the association between obesity and periodontitis according to the characteristics of subjects. The subjects of this study was 429 subjects aged 19 years or older from March to May, 2010. Data were analyzed with chi-square test, Multivariable logistic regression and Statistics were analyzed linear regression analysis using SPSS 18.0. WHR had dose-effect relationship with the number of sextants with periodontitis. With regard to relationships between obesity type and periodontitis depending on characteristics of objects, the WHR obesity group showed results higher than the normal group, for twice(OR: 2.24; 95% CI: 1.17-4.28) and three times or more(OR: 3.34; 95% CI: 1.53-7.27) in frequency of daily teeth brushing, 0-3 points(OR: 2.47; 95% CI: 1.09-5.59) and 4-6 points(OR: 3.99; 95% CI: 1.75-9.08) in the self-perception of stress level, and the group with 8 hours or more(OR: 4.20; 95% CI: 2.11-8.34) in the sleeping time. If anyone is judged to have obesity by WHR, we can say that the risk to have periodontitis together with it is 2.56 times more likely(95% CI: 1.58-4.13).
