This experiment was conducted to determine the effects of yeast culture (CYC-100) and antibiotics (Enduracidin, Nicarbazin and Bacfeed) on the performance and small intestinal microbiota of broiler chickens. Arbor Acres strain broilers were used to measure body weight gain, feed intake, feed conversion ratio, and the colony counts of microbes (Lactobacillus, Coliforms and yeast) in the small intestinal contents of broilers. Two hundred forty hatched broiler chickens were divided into 20 birds per each replicate and three replicates birds were given each of the four dietary treatments:Control, 23% crude protein; Treatment Ⅰ (T- 1 ), 20% crude protein;Treatment Ⅱ (T- H ), 20% crude protein (0.2% yeast culture); Treatment Ⅲ (T-Ⅲ), 20 crude protein (0.2% antibiotics). The results of this experiment were summarized as follows: 1. Liveability of broilers was higher in supplementation groups of antibiotics and probiotics(yeast culture) compared with non-supplemental group. 2. Average daily weight gain of broilers was 42.68g for control, 38.40g for T-Ⅰ, 40.38g for T-Ⅱ and 40.32g for T-Ⅲ. 3. Daily feed intake was signigicantly higher in control group than other three groups. Yeast culture and antibiotics supplementation did not increase feed intake compared with non-suppelemental group. 4. Broilers fed diets supplemented yeast culture (T-Ⅱ) and antibiotics (T-Ⅲ) out-weighed those of the basal group (T-Ⅰ) by 82.9g (5.1%) and 80.5g (5%), and required 80g (3.92%) and 60g (2.94%) less feed per kg of gain, respectively, at the end of six weeks. 5. The number of Lactobacillus counts was increased tenfold and Coliforms counts was decreased tenfold with supplementation of yeast culture, but the number of Lactobacillus and Coliforms counts was decreased tenfold with supplemention of antibiotics in small intestinal contents of broilers. Yeast culture supplemented group tended to have greater number of yeast than other two groups.

This experiment was carried out to compare biological availability of phosphorus(P) in locally produced dicalcium phosphate(DCP), tricalcium phosphate(TCP) and sodium acid phosphate (SAP) with 210 broiler-type chicks(Arbor Acres). Chicks were divided into 7 treatments consisted of DCP_1(low), DCP_2(high), TCP_1(low), TCP_2(high), SAP_1(low), SAP_2(high) and Control group for a period of 4 weeks. The results obtained are summarized as follows: 1. Liveability of Control, DCP_1, DCP_2, TCP_1, TCP_2, SAP_1 and SAP_2 were 90.0%, 96.7%, 96.7%, 93.3%, 93.3% 96.7% and 96.7%, respectively. 2. Body weight gain, feed intake and feed efficiency for 4 weeks feeding period were not significantly affected by the source of phosphorus supplements. However, it was found that chicks received DCP gained more body weight than the birds fed TCP or Control diet. 3. The relative biological availability of P in DCP, TCP and SAP fed broiler chicks were 98.1%, 94.23% and 100%, respectively. The results obtained from the present experiment indicated that the availability of P in DCP were better than that in TCP.

Obesity is growing problem in Korea. We had a case of bariatric surgery during gastric cancer operation. Patient was 29 year old Korean lady with early gastric cancer located in the lesser curvature side of the middle 1/3 of the stomach. Her body weight was 89 kg, height 163 cm, and thus body mass index was 33.5 kg/m2. Preoperative blood pressure was 130/90 mmHg, hemoglobin 12.9 g/dL, total lymphocyte count 3,280/mL, serum albumin 4.3 g/dL, CEA 1.1 ng/mL, CA 19-9 9.1 ng/mL, and alpha fetoprotein 2 ng/mL. Another associated disease was right thyroid follicular neoplasm. The chest X-ray was normal. After IM injection of 2,500 units of heparin 30 minutes before the induction of general anesthesia, she received curative subtotal gastrectomy and Roux en Y gastrojejunostomy when a malabsorption loop of 120 cm jejunum was incorporated between the Treitz ligament and the end to side jejuno-jejunostmy site at May 29th 2006. Her postoperative course was uneventful except a minor wound seroma and the elevations of serum amylase(up to 4 folds) and lipase(up to 2 folds). She lost her body weight 9 kg in 5th, 21 kg in 7th, and 27 kg in 10th postoperative months to became 61.5 kg. On follow up exams in July 2008, she gained 4 kg to overcome her weakness and fatigue. From the above result, the incorporation of a malabsorption loop during reconstruction phase of gastric cancer operation was a good option for obese gastric cancer patients especially in cases of early gastric cancer.

The proliferation of bone marrow stem cell compartment is thought to be under both positive and negative controls by cytokines and colony stimulation factors. Macrophage inflammatory protein-1α(MIP-1α) has been assessed for its potential to protect hematopoietic stem cells from cytotoxic effects of a cycle-specific antineoplastic agents. We have tested the ability of MIP-1α to suppress the proliferation of stem cell line Du.528.101 in variety of active status by using [³H]-thymidine incorporation test. The results were as follows. 1. The effect of MIP-1α on steady-state Du.528.101 cell represented the cell growth suppression at the concentration of 10, 50, 100nM of MIP-1α(P<0.001). 2. MIP-α stimulated the proliferation of Du.528.101 cells previously treated with IL-1 at the concentration of 5, 50nM of MIP-1α(P<0.01) 3. The suppression effect of MIP-1 on Du.528.101 cells at the concentration of 5, 50nM was shown when cells were treated with MIP-1α before activation with IL-1β(P<0.01). 4. The growth rate of synchronized cells were slower than that of non-synchronized ones, and MIP-1α represented the similar suppression effect on both synchronized and non-synchronized cells.

Using conventional textile techniques such as weaving, braiding, knitting and stitching it is possible to produce a wide range two and three dimensional fiber preforms. However, so far only a limited attention has been given to knitted fabrics in composite industry. This is mainly due to the opinion that knitted fabric reinforced composites posses low mechanical properties owing to their looped fiber architecture. But it is possible to obtain desired mechanical properties by selecting proper knitted fabric structure. In this paper, tensile failure load and displacement of one yarn, four yarns and knitted fabrics of ten yarns of kevlar fiber were determined experimentally in the unidirection. Mechanical properties of plain weft knitted fabrics reinforced composite intrusion beam for car side door application were investigated experimentally, which compared with desire value of American Fedral Motor vehicles Safety Standard (FMVSS) and presented the results.

Purpose: To understand the relationship between tibial bone defect and extent of medial release in total knee arthroplasty. Materials and Methods: We evaluated 32 knees in 22 patients with variable degrees of tibial bone defect on medial plateau has undergone total knee arthroplasty. In this study, 31 cases had been diagnosed as degenerative osteoarthritis and 1 case was osteonecrosis. We excluded cases with infection, traumatic arthritis, or neuropathic joints. With regard to gender, 29 cases were female and 3 cases were male. The following relationships were analyzed: preoperative degrees of tibial bone defect and varus deformity; the femorotibial angle of both weight-bearing whole extremity radiogram, distractive stress radiogram, and the extent of medial release. Results: Average tibial bone defect was 9.8±4.1 mm. Average femorotibial angle on weight-bearing whole extremity radiograph was varus 10.0o±6.2o. Average femorotibial angle on distractive stress radiograph was varus 0.7o±4.6o. Statistically the extent of medial release showed no significant relationship with the degree of tibial bone defect and femoro-tibial angle of whole extremity radiogram. However, it revealed a statistically significant relationship with the femorotibial angle on distractive radiogram (r=0.465, p=0.007). Conclusions: Preoperative distractive stress radiograph might be a useful method to predict the extent of intraoperative medial release during total knee arthroplasty.

The main purpose of this research was to investigate and compare the factors affecting the impact characteristics of body height and head height roundhouse kick of Taekwondo (TKD) players. In this study, 5 highly skilled TKD players participated. To measure the impact force, two accelerometers were fixed to a PVC pipe in a sandbag while the Viconⓒmotion analysis system captures the motion. Each subject performed 10 turning kicks trunk and face height in random order. Only the trial with the most accurate (most central impact) measurement was used in the statistical analysis (α<0.05). For impact force, there was a significant difference according to the height approximately 6400±898N for the mid section and 5419±F659N for the high section of TKD. With this reliable method of measuring high impact forces, due to the roundhouse kick, it is possible to investigate the differences of impacts due to various techniques i.e. punching power, kicking power, etc. Through this impact estimation from roundhouse kicking, different expected impact forces according to a players’weight division may be established. Thus, the safety provided by current martial arts suppliers may be investigated in the future.
