본 연구는 고급육 생산을 위하여 3원교잡종(LY×D) 90kg 전후의 비육용 돼지를 이용 하여 동일한 환경조건에서 비육후기 30일간 대조구(농후사료)와 한약재 급여구 (한약 찌꺼기 3% 농후사료 대체)로 나누어 각 구당 20두(암컷 10, 수컷 10)씩 혼합 사양하여 비육능력 및 도체품질에 미치는 효과를 조사한 결과는 다음과 같다. 사료요구율은 한약재 급여구가 대조구보다 낮았으며(p<0.05), 지육율, 정육율 및 등지방두께는 한약재 급여에 의한 유의적인 차이는 없었다. 최종등급에 있어 B등급이상 출현율은 한약재 급여구(50%)가 대조구(25%) 보다 25% 높게 나타났으며, 부위별 비율은 한약재 급여에 의한 유의적인 차이는 없었다. pH는 한약재 급여구가 대조구보다 낮았으며(p<0.05), WHC과 Colormeter에 의한 육색 및 지방색은 차이가 없었다. 지방산은 한약재 급여에 의한 유의적인 차이는 없었으나, 총콜레스테롤 함량은 한약재 급여구가 대조구보다 낮았다(p<0.05). Instron을 이용한 신선육 전단가, 가열육의 조직감은 한약재 급여에 의한 차이는 없었으나, 관능검사에 의한 신선육의 육색, 지방색, 향 및 상강도는 한약재 급여구가 대조구 보다 높았으며, 가열육의 육색, 지방색, 맛도 높게 나타났다. 이상 본 시험에서 얻어진 결과를 보면 돼지에 한약재 찌꺼기를 급여함으로써 비육능력 및 도체품질을 향상시키는 것으로 나타났다. This study was conducted to investigate the effct of feeding used medicinal herbs on growth performance and carcass quality of finishing pigs. Ten LY×D boars and 10 gilts weighing approximately 90kg were randomly assigned to each of control and treatment groups. Control group animals received a regular fattening type diet ad libitum for 30 days' the other group(treatment) had the same diet 3% of which was substituted by a mixture of used medicinal herbs on a as fed basis. The partial substitution of the diet with used medicinal herbs did not affect average daily gain, but resulted in an increased feed conversion efficiency(P<0.05). The dietary treatment decreased the lean meat weight and the frequency of the A and B grade carcass by 25%, with no effect on the lean meat percentage, backfat thickness, or retail cut percentage. Physical properties, fatty acid composition and mechanical and sensory evaluations were performed on the loin eye area; pH was lower in the treatment group, but WHC, meat and fat color were not different between the two groups. The dietary treatment resulted in an decreased cholesterol content, with no effect on fatty acid composition or shear force. Sensory evaluation revealed an improvement in meat and fat color, aroma and marbling scores of fresh meat and also the meat and fat color and flavor of cooked meat. Tenderness, juiciness, springiness and overall acceptability, however, did not change following the treatment. Results indicate that used medicinal herbs can be added into the diet with no disadvantageous effect in finishing pigs. The advantageous effects of the herb observed in this study, namely increased feed conversion efficiency and improved carcass quality, warrant further investigation.

Conjugated linoleic acid (CLA), when incorporated into mouse liver microsomal membranes, selectively inhibits the mutagenesis of 2-amino-3-methylimidazo[4,5-f] quinoline (IQ). Nine-week old female ICR mice were given (p.o.) 0.1 mL olive oil alone (control), 0.1 mL olive oil plus 0.1 mL linoleic acid, or 0.1 mL olive oil plus 0.1 mL CLA, twice weekly for four weeks. The animals were then sacrificed and liver S-9 fractions were prepared. Activation of IQ for mutagenesis by the liver S-9 from CLA-treated mice was significantly reduced in comparison wit liver S-9 from control or linolic acid-treated mice. By contrast, the activation of 7,12-dimethylbenz[a] anthracene (DMBA) and benzo[a] pyrene (BP) was unaffected. Hence, CLA incorporated into phospholipids may selectively affect cytochrome P450 isozymes responsible for activating IQ, but not those which activate BP or DMBA. The addition of free CLA or the methyl esters of CLA, linoleic acid, or oleic acid, to control S-9 inhibited the activation of all three mutagens (IQ, BP, and DMBA).

Osteoarthritis is a disease that affects the articular cartilage and osseous tissue, and can be worsened by aging, overweight status, and post-traumatic arthritis. The present study aimed to evaluate the effect of ID-CBT5101 (tyndallized Clostridium butyricum) on bone metabolism and the inflammatory response in a monosodium iodoacetate-induced rat model of osteoarthritis. ID-CBT5101 was administered orally at doses of 10<sup>8</sup> or 10<sup>10</sup> CFU/day for 2 weeks before direct injection of monosodium iodoacetate (3 mg/50 μl of 0.9% saline) into the intra-articular space of the rats’ right knees. The rats subsequently received the same doses of oral ID-CBT5101 for another 4 weeks. We evaluated the treatment effects based on serum biomarkers, mRNA expression, morphological and histopathological analyses of the knee joints, and weight-bearing distribution analysis. Compared with those in control rats, the IDCBT5101 treatments significantly reduced the serum concentration of inflammation and bone metabolism markers (i.e., COX-2, IL-6, LTB<sub>4</sub>, and COMP), and significantly increased the concentration of IFN-γ and glycosaminoglycans. In addition, the ID-CBT5101 treatments inhibited the mRNA expression of matrix metalloproteinases and tissue inhibitors of metalloproteinases (i.e., MMP-2, MMP-3, MMP-9, MMP-13, TIMP-1, and TIMP-2). Furthermore, the ID-CBT5101 treatments effectively preserved the knee cartilage and synovial membrane, and significantly decreased the amount of fibrous tissue. Moreover, compared with that of the negative control group, the ID-CBT5101 treatments increased the weight-bearing distribution by ≥20%. The results indicate that ID-CBT5101 prevented and alleviated osteoarthritis symptoms. Thus, ID-CBT5101 may be a novel therapeutic option for the management of osteoarthritis.

The DPPH (1,1-diphenyl-2-picryl hydrazyl radical scavenging activity, % of control at maximum plants extract concentrations of 2500mg/L) in the thirteen natural plant pigments (black rice, purple sweet potato, yellow bitter melon, yellow paprika, red cabbage, yellow gardenia, blue gardenia, Chinese foxglove, mulberry leave, onion peel, grape peel, mulberry and red beet) ranged from 88.9% for red cabbage to 18.0% for blue gardenia. The highest total polyphenol content (404.2μg/ml) was measured in the onion peel pigment, and the lowest was in Chinese foxglove pigment (11.4μg/ml). The red cabbage had the highest total flavonoid amount which was 95.5μg/ml. The antimicrobial activities of the natural plant pigments were evaluated using the agar diffusion method. Most of the natural pigments for <I>Bacillus subtilis, Micrococcus luteus, Escherichia coli</I>, and <I>Vibrio parahaemolyticus</I> showed the clear zone formation of growth inhibition. Purple sweet potato, mulberry, mulberry leaf, grape peel, and blue gardenia showed high antimicrobial activities. These findings suggest that the pigments derived from natural plants had high biological activities, and exhibited different properties depending on each kind of pigments. Therefore these plant resources, having active functional components, can be used as excellent materials for natural cosmetics and food supplements.</P>

Phosphorus is known to pile-up at the silicon surface when it is thermally oxidized. A thin layer, about 40nm thick from the silicon surface, is created containing more phosphorus than the bulk of the emitter. This layer has a gaussian profile with the peak at the surface of the silicon. In this study the pile-up effect was studied if this layer can act as a front surface field for solar cells. The effect was also tested if its high dose of phosphorus at the silicon surface can lower the contact resistance with the front metal contact. P-type wafers were first doped with phosphorus to create an n-type emitter. The doping was done using either a furnace or ion implantation. The wafers were then oxidized using dry thermal oxidation. The effect of the pile-up as a front surface field was checked by measuring the minority carrier lifetime using a QSSPC. The contact resistance of the wafers were also measured to see if the pile-up effect can lower the series resistance.

The corrosion failure of electronic devices has been a major reliability concern lately. This failure is an ongoing concern because of miniaturization of integrated circuits(IC) and the increased use of polymers in electronic packaging. In this paper plasma-polymerized thiophene films were considered as a possible candidate for an interlayer dielectric for multilever metallization of ultra large scale integrated (ULSI) semiconductor devices. The protective ability of above films as a function RF power in an 3.5 wt.% NaCl solution was examined by electrochemical methods and contact angle measurement. The protective efficiency of the film increased with increasing RF power, which induced the higher degree of cross-linking and hydrophobicity of the films.

질산 용액을 이용한 처리를 통해서 실리콘 웨이퍼 위에 누설 전류가 thermal oxidation 방법과 비슷한 수준의 얇은 실리콘 산화막을 형성할 수 있다. 이러한 처리 방법은 thermal oxidation에 비해서 낮은 온도에서 공정이 가능하다는 장점을 가진다. 이 때 질산 용액으로 68 wt% HNO₃을 쓰는데, 이 용액에만 넣었을 때에는 실리콘 산화막이 어느 정도 두께 이상은 성장하지 않는 단점이 있다. 그렇기 때문에 실리콘 웨이퍼를 68 wt% HNO₃에 넣기 전에 seed layer 산화막을 형성 시킨다. 본 연구에서는 p-type 웨이퍼를 phosphorus로 도핑해서 에미터를 형성 시킨 후에 seed layer를 형성 시키고 68 wt% HNO₃를 이용해서 에미터 위의 실리콘 산화막을 성장 시켰다. 이 때 보다 더 효과적인 seed layer를 형성 시키는 용액을 찾아서 실험하였다. 40 wt% HNO₃, H₂SO₄-H₂O₂, HCl-H₂O₂ 용액에 웨이퍼를 10분 동안 담그는 것을 통해서 seed layer를 형성하고, 이를 121?C인 68 wt% HNO₃에 넣어서 실리콘 산화막을 성장시켰다. 이렇게 형성된 실리콘 산화막의 특성은 엘립소미터, I-V 측정 장치, QSSPC를 통해서 알아보았다.
