This study was carried out to investigate the growth characteristics, yield, and chemical compositions of corn hybrids for silage according to the drainage depths in a lowland paddy field. The experimental design was arranged in a randomized block design with four treatments and three replications. The drainage depths of the four treatments were 0 cm, 20 cm, 30 cm and 50 cm. Tip-filling degree, ear length, and ear circle were higher in the 30 cm and 50 cm treatments compared with the other treatments (p < 0.05); but the plant length, leaf length, leaf width, ear height, stem diameter, and stem hardness were not significantly different (p < 0.05). The brix was higher in the order of 20 cm > 0 cm > 50 cm > 30 cm treatment. The fresh yield, dry matter yield, and TDN yield increased as the drainage depth increased (p < 0.05). The crude-protein and crude-ash content were highest in the 50 cm treatment (p < 0.05), but the crude-fat, NDF, ADF, and crude-fiber levels were not significantly different (p < 0.05). The total mineral content was higher in the order of 0 cm > 30 cm > 20 cm > 50 cm treatment (p < 0.05). Fructose, glucose, and sucrose were highest in the 20 cm treatment. The total amino-acid (EAA + NEAA) content was the highest in the 50 cm treatment. Based on these results, greater drainage depths increased the yield and feed value of silage corn.

This study was carried out to investigate the growth characteristics, yield, and chemical compositions of winter forage crops cultivated after rice harvest in the central inland region. The experimental design was arranged in a randomized block design with three replications. The treatments consisted of 4 species (Rye, Oat, Triticale and Italian ryegrass), and varieties were "Marton", "Donghan", "Shinyoung" and "Kowinnearly", respectively. As a result, dry matter yield and TDN yield were higher in rye than in the other winter forage crops, and lowest in Oat(p<0.05). Crude protein and crude fat content were significantly higher in Italian ryegrass(p<0.05). However, Crude ash and ADF content did not show significant difference among winter forage crops. NDF content was higher in order of Rye > Triticale > Oat > Italian ryegrass(p<0.05). TDN and total amino acid content (EAA+NEAA) were higher in order of winter forage crop with high crude protein content (Italian ryegrass > Oat > Triticale > Rye). Total mineral content was higher in order of Rye > Triticale > Oat > Italian ryegrass(p<0.05), and total free sugar content was higher in order of Oat > Italian Ryegrass > Triticale > Rye(p<0.05). Compared with the results above, Italian ryegrass and Oat are high in crude protein, TDN, amino acid and free sugar content. Rye and Triticale have the merit that feed value is decreased but high yield(dry matter and TDN yield) can be maintained. Therefore, it is advantageous to grow Rye and Triticale as winter forage crops after rice harvest in the central inland region.

이상무,박웅렬,김영직,Lee, Sang-Moo,Park, Woong-Yeoul,Kim, Young-Jik 한국축산식품학회 2010 한국축산식품학회지 Vol.30 No.3

The effects of rosemary and $\alpha$-tocopherol, added individually or in combination, on broiler performance, thiobarbituric acid reactive substance (TBARS), total plate count (TPC) and meat color of chicken thigh meat were investigated. Three hundred broiler chicks divided into five groups were fed a basal diet (control) or basal diet supplemented with 5 g rosemary/kg (T1), 10 g rosemary/kg (T2), 200 mg $\alpha$-tocopherol/kg (T3), or 5 g rosemary/kg + 200 mg $\alpha$-tocopherol/kg (T4) for 5 weeks. Following slaughter, chicken meat was stored at $4^{\circ}C$ for 10 days. All treatments did not influence the performance. Rosemary supplementation delayed lipid oxidation in thigh meat during refrigerated storage. T2 was significantly (p<0.05) more effective in delayed lipid oxidation compared to T1, but was inferior to T3. Samples containing a combination of antioxidant had lower TBARS values than those containing the individual antioxidants, indicating a synergistic effect. TPC was significantly increased (p<0.05) in thigh meat of all groups throughout the refrigerated storage. The T3 and control groups showed TPC counts that did not differ from each other during the entire storage period. However, rosemary supplementation was associated with bacterial counts that were significantly lower (p<0.05) than the control and $\alpha$-tocopherol groups at day 3 of storage and thereafter. For this period, T1 presented TPC counts that were significantly higher than the T2 group (p<0.05). At all storage times, the thigh meat of rosemary-fed chickens was redder than control (higher $a^*$), while no differences in $L^*$ and $b^*$ values were found. A synergistic effect was obtained from the combination of rosemary with $\alpha$-tocopherol, whereas individual use of the antioxidants significantly improved color stability compared to the control.

This study was carried out to investigate the growth characteristics, yield and feed value of Sorghum${\times}$Sudangrass hybrid for silage according to the drainage depths in the paddy field of lowland. The experimental design was arranged in a randomized block design with four treatments and three replication. The drainage depths of four treatments were 0cm, 20cm, 40cm and 60cm, respectively. Plant length, leaf length and leaf number were not significantly different, but leaf width increased as the higher the drainage depth(p<0.05). The number of dead leaf was higher in the order of $60cm>0cm{\geq}40cm{\geq}20cm$ treatment(p<0.05). Green degree was higher in the order of 20cm > 40cm > 0cm > 60cm treatment(p<0.05). Stem diameter and stem hardness increased significantly as drainage depth increased from 0cm to 60cm(p<0.05). Also, fresh yield, dry matter yield and TDN yield increased as the higher the drainage depth(p<0.05). Crude protein and TDN content were the highest in 40cm treatment(p<0.05). Crude ash was higher in the order of 20cm > 40cm > 0cm > 60cm treatment(p<0.05). ADF and NDF content were the highest in 0cm treatment(p<0.05). Total mineral content was higher in the order of 20cm > 0cm > 40cm > 60cm(p<0.05). Free sugar content(fructose, glucose and sucrose) was the highest in 0cm treatment(p<0.05). Total amino acid(EAA+NEAA) was higher in 40cm than the other treatments(p<0.05). There is a difference in the content of ingredients(crude protein, TDN, mineral, free sugar and amino acid) according to the treatments. But considering dry matter yield and TDN yield, Sorghum${\times}$Sudangrass hybrid cultivation is advantageous to set the drainage depth of about 60cm in the paddy field of lowland.

The magnetic field profiles near the surface of a $Sm_1Ba_2Cu_3O_{7-\delta}$ coated conductor(CC-tape) under magnetic field and current that were applied simultaneously with phase differences ${\phi}s$ were measured using scanning Hall probe method. Measurements were carried out along the elliptic load lines with $\phi=90^{\circ}\;and\;45^{\circ}$ for some $B_{peak},\;I_{peak}$ values. From the measured field profiles, sheet current density J(x, $B_a,\;I_a$) and magnetic flux density $B_0(x,\;B_a,\;I_a)$ profiles in the CC-tape were calculated. Using these J(x, $B_a,\;I_a$) and $B_0(x,\;B_a,\;I_a)$ profiles, we estimated the hysteresis energy loss Q in the CC-tape. The estimated Qs, together with our previous results for $\phi=0^{\circ}$ from [9], were compared with theoretical values based on Brandt's calculation.

Purpose ; Iension-type headache is the most common headache. The effect of acupuncture for headache is already known, but the methods and technique of acupuncture is varied. Choice of acupuncture points is mostly relied on experience. Moreover, objective evaluation of acupuncture effects is lacking. Objective ; The objective of this study is to assess the difference of effects between dry needling on trigger point and dry needling on remote acupuncture point. The patients who were diagnosed as tension-type headache and administrated herb-medication were divided into two groups: Trigger point dry needling group and remote acupuncture point dry needling group, matching in sex, age. The degree of pain was measured by visual analogue scale(VAS) two times, before and after dry needling. Conclusion ; VAS showed significant decrement after dry needling on tension-type headache in both groups, but there was no statistically significant difference between two groups according to sex, age and duration. In addition, it is not statistically approved that there exists the difference of VAS between two groups about the treatment effects.

The effects of dietary supplementation with Kalopanax pictus branch, leaves, and extracts on performance, proximate composition, pH, total phenol and 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity, cholesterol and fatty acid composition of chicken meat. Broiler chicks were fed for 5 weeks with a diet containing 5% Kalopanax pictus branch (T1), 2% Kalopanax pictus leaves (T2), and 5% Kalopanax pictus extracts (60% leaves + 40% branch) (T3). T1 and T3 resulted in much better feed conversion than T2. In proximate composition, crude fat of chicken meat was increased, but not signi-ficantly (p>0.05) in Kalopanax pictus-supplemented diets than control diet. Total phenol contents and DPPH radical scavenging activity were significantly increased (p<0.05) by the dietary-supplementation with Kalopanax pictus branch and leaves compared to the control diet. Total and high density lipoprotein cholesterols of treatment groups were higher than the control group, and control group low density lipoprotein cholesterolwas higher than treatment groups (p<0.05). Especially, T3 was significantly (p<0.05) more effective in improving cholesterol compared to other treatment groups. The treatment groups (especially T3) showed significantly higher total fatty acid and unsaturated fatty acid compositions compare to the control group.
