The characteristics of concentrations and loads of Total Nitrogen(T-N), Total Phosphorus(T-P), and Chemical Oxygen Demand (COD) in mountain stream water were examined from September 2000 through August 2001. The 92.5-ha study watershed in Chungbuk Province consists of 59% mixed forest and 30% coniferous forest. Streamflow was measured and water samples were collected at about 10 day intervals for dry days and at 2-6 hour intervals for a storm event at the study watershed outlet. The mean concentration of COD in streamflow for rainy days was significantly (p < 0.05) higher than for dry days. The mean concentrations of T-N and T-P in vegetation growing season (May to October) were lower than those in vegetation dormant season (November to April). Low concentrations of pollutants during vegetation growing season are likely due to the heavy demand for nutrients by the vegetation and biological activity associated with a warming of soil. The ratios of pollutants loads during storm periods to annual pollutants loads were 87% for T-N, 83% for T-p, and 87% for COD. The unit loads of pollutants for study area were estimated at 5.9 kg/ha $\cdot$ yr for T-N, 0.15 kg/ha $\cdot$ yr for T-p, and 23.9 kg/ha $\cdot$ yr for COD. The removal efficiency of pollutants in study area were 24% for T-N, 58% for T-P and 66% for COD, indicating that a study area shows water purification function.

Purpose To investigate the added value of right down decubitus (RDD) CT when determining adjacent organ invasion in cases of advanced gastric cancer (AGC). Materials and Methods A total of 728 patients with pathologically confirmed T4a (pT4a), surgically confirmed T4b (sT4b), or pathologically confirmed T4b (pT4b) AGCs who underwent dedicated stomach-protocol CT, including imaging of the left posterior oblique (LPO) and RDD positions, were included in this study. Two radiologists scored the T stage of AGCs using a 5-point scale on LPO CT with and without RDD CT at 2-week intervals and recorded the presence of "sliding sign" in the tumors and adjacent organs and compared its incidence of appearance. Results A total of 564 patients (77.4%) were diagnosed with pT4a, whereas 65 (8.9%) and 99 (13.6%) patients were diagnosed with pT4b and sT4b, respectively. When RDD CT was performed additionally, both reviewers deemed that the area under the curve (AUC) for differentiating T4b from T4a increased (p < 0.001). According to both reviewers, the AUC for differentiating T4b with pancreatic invasion from T4a increased in the subgroup analysis (p < 0.050). Interobserver agreement improved from fair to moderate (weighted kappa value, 0.296-0.444). Conclusion RDD CT provides additional value compared to LPO CT images alone for determining adjacent organ invasion in patients with AGC due to their increased AUC values and improved interobserver agreement.

This study investigated the effect of belly fat on the plasma lipid concentrations in rats. The results were obtained from the rats that had been fed the experimental purified diets containing 5％ corn oil (C) as the control, 5％ commercial lard (Tl), 5％ belly fat (T2), 10％ belly fat(T3), and those given diet(T4) by feeding either C or T3 alternately every 3 days for 30 days. The food intake and food efficiency were not show any significant difference among the treatments. The body weight gain tended to significantly increased when the feeding of added-belly fat in diets (p＜0.05). The plasma triacylglycerides of T3 was higher than the other treatments, and significantly elevated as the number of feeding days of the diets with the belly fat passed when compared to diet C (p＜0.05). The plasma total cholesterol of T3 showed the highest levels in the treatment groups, and was high in the order of T1, T2, T4, and there was a significant difference between the rats given the diet with belly fat and C (p＜0.05). The plasma HDL-C of T2 and T3 was showed the lowest levels in the treatment groups. The plasma HDL-C of T1, T2, T3 and T4 groups were significantly decreased as the number of feeding days of the diets with the belly fat increased when compared to diet C (p＜0.05). The plasma LDL-C and Al of T3 showed the highest levels in the treatment groups, and the levels were in order of T1, T2, T4. There was a significant difference between the groups of rats given the belly fat and C (p＜0.05). The bleeding times significantly decreased as the number of feeding days of the belly fat diets increased, and T3 showed the lowest levels, there was a significant difference among the treatment groups (p＜0.05). The whole blood clotting times of T3 showed the lowest values, and significantly decreased according to the number of days of the rats were fed the belly fat diet (p＜0.05). These results showed that frequent consumption and high intake of pork belly can elevate the plasma triacylglyceride and cholesterol levels, and also accelerate red thrombus formation because belly fat contains high levels of saturated fatty acids and cholesterol.

This study was conducted to assess the effects of organic and inorganic copper on performance in growing pigs. A total of 100 pigs, average age 63 d and initial body weight 21.46${\pm}$1.13 kg, were assigned to five treatment groups. Dietary treatments included i) CON (basal diet, 0 ppm Cu), ii) T1 (basal diet with 67 ppm Cu as cupric sulfate, $CuSO_4$), iii) T2 (basal diet with 134 ppm Cu as $CuSO_4$), iv) T3 (basal diet with 67 ppm Cu as cupric methionate, CuMet) and v) T4 (basal diet with 134 ppm Cu as CuMet). Throughout the entire experimental period, ADG (average daily gain), ADFI (average daily feed intake) and G/F (gain: feed) ratios showed no significant differences. The dry matter digestibility was improved in the T1, T2, T3, and T4 treatments (p<0.05), as compared with CON. Nitrogen digestibility was improved in the T3 treatment group as compared with CON (p<0.05). As compared with the T1 treatment group, fecal pH values were improved in the CON, T3, and T4 treatment groups (p<0.05). Fecal Cu concentrations were significantly lower in the CON, T3, and T4 treatment groups than in T1 and T2 (p<0.05). The incidence of diarrhea was reduced when the pigs were fed on the T2, T3, and T4 diets as compared with CON. In conclusion, diets supplemented with 67 or 134 ppm Cu as CuMet may prove effective in improving nutrient digestibility and fecal pH value in growing pigs, and fecal Cu concentrations may be reduced by CuMet supplementation.

This study was carried out to investigate the growth characteristics, yield and chemical compositions of corn hybrids for silage according to ridging times in the paddy field cultivation. The experimental design was arranged in a randomized block design with five treatments and three replication. The ridging times of five treatments were untreated (C), 7 leaves (T1: 31 days), 8 leaves (T2: 37 days), 9 leaves (T3: 42 days) and 10 leaves stage (T4: 48 days after sowing) of silage corn. The ridging treatments (T1, T2, T3, T4) were higher (p<0.01) dry matter yield and TDN yield than the unridging treatment (C). However, there were no significant differences among T1, T2, T3 and T4 treatments. The Crude protein content of unridging treatment was decreased (p<0.01), while NDF content was increased (p<0.01) compared to ridging treatments. The contents of mineral and amino acid in ridging treatments were higher than unridging treatment (p<0.05, p<0.01). In particular, mineral and amino acid contents were the highest in T4 and T1, respectively (p<0.01). Based on the above results, ridging work is to be increased the yield quantity and nutritional value of silage corn. And the best result was obtained in T4 treatment of ridging treatments.
