In the method of obesity treatment, Dietary method, Exercise method, Behavior method, and Drug method, Dietary method is the most important control method of obesity. The aim of this study is that evaluate the weight reduction effect of the specific low calorie diet products (KSD I and 2) in obese women. Twenty five women who were volunteer participated in this study. They have no heart diseases and metabolic diseases. we classified two groups : obese group and standard group. Anthropometric indices were measured in all subject for four times. Venous blood sample were taken to determine the lipid profiles, glucose level, and liver function test. In obese group, body weight were reduced 2.85±1.46kg, but showed statistically non-signicicant. Body mass index were gradually reduced, 1.09±0.93kg/m^2(p<0.05).In blood analyses, total cholesterol were reduced 10.61 ±33.4mg/dℓ ( p<0.05). KSD 2 significantly inhibited maltase, sucrase and α-glucosidase from rat intestine, and porcine pancreatic lipase, although KSD I inhibited only the sucrase.

Le-Fort Ⅰ Osteotomy is considered by many surgeons to be a safe and predictable method for correcting various dentofacial deformities. However, there are controversial options concerning the stability of two-jaw surgery (Le-Fort Ⅰ osteotomy and sagittal split ramus osteotomy) compared to single mandibular surgery (sagittal split ramus osteotomy). The purpose of this study was to evaluate the post-operative stability of mandible in two-jaw surgery and single mandibular surgery, to help the establishment of accurate treatment planning in patients with a skeletal class Ⅲ malocclusion. There were 15 patients who had been undergone two-jaw surgery and 20 patients who had been undergone single mandibular surgery. Lateral cephalograms of these 2groups ; Preoperation and immediate postoperation, postoperatively 1month, postoperatively 3months, at the latest follow up(>6months) ; were analyzed by linear measurement to evaluate changes in position (hard tissue B, Pogonion point) and compare relapse both group. The results obtained were as follows ; In view of B-point, the horizontal relapse rate of single mandibular surgery was 10.17% at post-op 1months, 12.52% at post-op 3months, 13.01% at post-op 6months and two-jaw surgery was 10.23% at post-op 1month, 11.84% at post-op 3months, 12.97% at post-op 6months. the horizontal relapse rates of Pogonion point were 10.78 at post-op 1month, 12.21% at post-op 3months, 12.98% at post-op 6months in single mandibular surgery and those were 10.27% at post-op 1month, 11.33% at post-op 3months, 12.01% at post-op 6months in two-jaw surgery. In terms of vertical relapse rate, rates of B point were 22.96% at post-op 1month, 28.30% at post-op 3months, 29.56% at post-op 6months in single mandibular surgery and 21.14% at post-op 1month, 25.45% at post-op 3months, 28.86% at post-op 6months in two-jaw surgery. Those of Pogonion point were 26.63% at post-op 1month, 28.40% at post-op 3months, 29.29% at post-op 6months in single mandibular surgery and 20.20% at post-op 1month, 25.44 at post-op 3months, 27.68% at post-op 6months in two-jaw surgery. There were no statistical difference between single mandibular surgery and two-jaw surgery in mandibular stability.

For the endurance test, it is necessary to test the portable electric tools under the same condition as the actual operation condition. It is also essential that the test equipment is convenient to fix the tool. Those are necessary to control the loaded torque and to acquire and analyze the test data with a computer. In this study, we have developed an endurance test equipment for portable electric tools, where a hydraulic control system with a proportional relief valve was applied to control the load for the test. The developed test equipment used an industrial hydraulic pump as a load supplier to ensure a firm endurance of the test equipment itself. The data acquisition system has been automated by composing with a personal computer and RS-232C communication nets. This test equipment reduced the manhour for the test and also improved the reliability of the tested data which were measured and graphed.

The objectives of food waste composting are to treat the wastes and to reclaim valuable substances present in the wastes for possible reuse. In the process of food waste composting, however, the salt in the compost can be retained within the soil for extended periods of time. In this study, therefore, a series of experiments were carried out to investigate the leaching characteristics of the salts in the compost of food waste. The resalts obtained from this study can be concluded as follows: 1. The composting process reduced the amount of waste to management because the 80% of water content in the food waste was lowered to 10% of that in the compost, and organics substances in the food waste were decomposed into CO₂, NH₃, water, and various inorganic substances. 2. It was found that the amount of toxic substances such as heavy metals in the food waste were very little, therefore, the metal concentration might not cause any adverse effect on the growth of the corps. 3. The concentrations of leachable cations in the compost were 10∼20% higher than those in the food waste of around 1000 meq/kg. And, SAR of the leachates of the food waste and compost was around 3. 4. The leaching rate of the salts in the compost was decreased with increasing the composting period. Also, the electric conductivities of initial leachate were increased with increassing the mixing ratio of the compost to the soil used. 5. The threshold dose of the compost per day per unit area of the soil was estimated with the following equation: mmho 12.0meq·cm kg 1.65L Threshold dose= 5______ × ___________ × _______ × _____ cm L·mmho 1200meq d·㎡ = 0.08kg/㎡/d

Objectives: Posterior cervical microscopic laminoforaminotomy has been a preferred procedure for a posterolateral cervical disc or foraminal stenosis. However, neckpain from wide skin incision and muscle injury are some of disadvantages. The authors performed cervical microscopic laminoforaminotomy with METRx™ tubular dilator system and were compared the results with classical cervical microscopic foraminotomy. Methods: Six patients underwent posterior cervical microscopic laminoforaminotomy using the METRx™ during 6 months. We have selected 10 patients from our institution as a comparison group. Preoperative and postoperative pain score composed of the radicular and neck component was examined and disability score also recorded. Diameters and lengths of laminoforaminotomy on the postoperative CT also were compared with two methods Results: Postoperative pain scores to the radiculopathies were not different but postoperative pain scores to the neckpain on the follow up periods were significantly different. The average vertical and transverse diameters of the laminoforaminotomy defect on the postoperative CT scans were not different between two groups. Average hospital stay of the classical methods was 8.8±7.5 days comparison with 4.5±0.54days of new procedure. Conclusions: Posterior cervical microscopic laminoforaminotomy with METRx™ systems seems to provide similar decompression and clinical results as classical methods compared to classical methods and shows superior results for postoperative neckpain and hospital stays.

後期飼料를 3주령부터 조기에 급여한 9주령 Hubbad鷄肉의 3부위 근육을 공시육으로 하여 4℃에서 저장하면서 경시적(도살직후 저장후 2일 4일 7일)으로 지질의 함량을 추출하고 지방산의 조성을 GLC로 분석한 결과 다음과 같은 결과를 얻었다. 1. 지질함량은 도살직후 대퇴부위가 2.67%로 가장 높고 흉심부가 2.38%, 근위 1.28% 가장 낮았으며, 저장기간에 따른 지질함량의 변화는 3부위 모두 저장기간의 경과에 따라 지질함량이 감소하였다. 2. GLC로 분석한 지방산은 3부위 모두 myristic acid(14:0)로 부터 arachidonic acid(20:4)까지 10種을 분리 동정하였다. 3. 함량이 제일 높은 지방산은 세부위 모두 불포화 지방산인 Oleic acid로 40.7~45.5%였고 다음 Palmitic acid로 20.5~27.9%였으며 linoleic acid는 6.9~18.3%로 타육류에 비해 필수지방산인 linoleic acid의 함량이 높았다. 4. 3部位 모두 저장시간이 경과함에 따라 포화지방산의 함량이 증가되고 불포화지방산의 함량은 상대적으로 감소되었다. The meat cut 3 parts of leg, breast and gizzard of broiler-Hubbard at 9 weeks fed early finisher diet from 3 weeks were stored at 4℃ for four levels, immediately after slaughtering, 2 days, 4 days and 7 days after storing in order to extract lipid contents and fatty acid compositions was analyzed by the GLC method. The results obtained in this experiment were summarized as follows: 1. Lipid contents were the highest with 2.67% in the leg immediately after slaughtering and the lowest, with 1.28% in the gizzard. Fatty acid compositions were decreased in all the three parts as the storage time passed. 2. Ten fatty acids from myristic acid(14:0) to arachidonic acid(20:4) in all the there parts were identified by GLC. 3. The highest fatty acid was oleic acid with 40.7 to 45.5% and the next, palmitic acid with 20.5 to 27.9%. Linoleic acid was higher with 6.9 to 18.3% in broiler-Hubbard then in the other broiler. 4. As the storage time passed, saturation fatty acid increased and unsaturation fatty acid decreased relatively.
