The analysis of soft tissue profile is an important paramenter in the esthetic aspect of facial deformity correction. The authors have studied on the soft tissue changes after the orthognathic surgery. We grouped the 30 patients according to the operation methods ; group 1 S.S.R.O. only, group 2 S.S.R.O.+Genioplasly, group 3 LeFortⅠ+S.S.R.O. The results were obtained as follows ; 1. In Group 1, the ratio of horizontal changes of hard tissue to soft tissue at 1 to Stmi, B to Si, Pog/SPog is 1.09, 0.96, 1.12 with postop. immediately, 0.98, 0.89, 0.98 with postop. 6 months. 2.

This study was conducted to analyze genetic characteristics and to detect the specific marker for HANWOO (Korean Cattle) using RAPD (Random Amplified polymorphic DNAs). We collected blood samples from HANWOO, Angus, Charolais, Hereford and Holstein and obtained genomic DNA from the blood of 10 individuals randomly selected within the breeds. One hundred fifty primers were chosen randomly and were examined for polymorphism and 10 kinds of primer showed polymorphic RAPD band pattern between and among the breeds. Arbitrary primer #4 showed dimorphic band pattern. HANWOO specific bands were observed from the primer #5, #8, #9 and #18 analysis. Primer #14 showed the Charolais specific band pattern in the genetic analysis between Charolais and Holstein. Primer #13 created many bands from RAPD products and showed wide range of polymorphism within brew, resulting that RAPD amplification using primer #13 was suitable for paternity test of family having pedigree and unrelated binds different from those of parent might be a evidence for exclusion from pedigree of family. A total of 66 polymorphic RAPD bands from ten different primers were used to analyze the genetic relationship of HANWOO with other 4 breeds. Genetic similarities among breeds were estimated using these 66 RAPD markers. The genetic similarity coefficient between HANWOO and Holstein was 0.737 and was higher than those of any other pair of breeds.

The results of implant therapy for the functional rehabilitation of tumor-patients are presented and discussed. It can be shown, that mandibular implants without osteoplasty show a similar low failure rate of about five percent as implants used in a control group of edentulous patients. Implants used in conjunction with osteoplasty and maxillary implants show a less favourable prognosis. Because of special problems and possible complications, especially in irradiated patients, we suggest a restrictive indication for implantations and a close follow-up of the patients.

This study was conducted to established method of culture for Paecilomyces japonica using an egg. Mycelia grew favorably at the temperature of 22~26℃ on eggs. 5.1g of dry matter basis(average 7.2㎝ of longer and 199.6 of numbers) of artificial fruiting bodies were harvested at 60 days after inoculation from one of egg. Commercial fruiting bodies of Paecilomyces japonica from silkworms was used for comparative nutriental contents. Cordycepin contents of fruit bodies of Paecilomyces japonica cultivated on eggs and silkworms were not significantly different. Crude fat contents of fruiting bodies of Paeilomyces japonica cultivated from eggs was significantly higher than from silkworms(P<0.05). Mn and Cu contents of fruiting bodies of Paecilomyces japonica cultivated from silkworms were significantly higher than from eggs(P<0.05),but Na, Mg, Fe and Zn contents were significantly higher from eggs(P<0.05). Glycine, Arginine and Proline contents in the fruiting bodies of Paecibmyces japonica cultivated from silkworms were tend to higher than from eggs, but Serine, cystein, methionine, isoleucine and phenylalanin were tend to higher from eggs. These results were made possible that possible mass production of artificial fruiting bodies of Paecilomyces Japonica cultivated on eggs.

PVC membrane, which has been used for membrane of electrolyte sensors, shortened sensor lifetime due to poor adhesion to sensor surface and exhibited difficulty in standardization and mass-production. To overcome these problems, the membrane solution was prepared with neutral carrier, matrix(TEOS:DEDMS=1:3), solvent(ethanol), and a catalyzer(HCl). The fabricated electrolyte sensors showed typical electrical characteristics of MISFET (metal-insulator-semiconductor field-effect transistor). The K-, Ca- and Na-ISFETs showed sensitivity of 53, 2b and 50 mV/decade in wide concentration range, respectively. The response time was about 90 seconds and the drift was 0.05mV/hour. These results suggest that the sol-gel method and the lift-off technique can be applied to formation of membranes and expected to improve mass-productivity, standardzation of the sensors.

본 연구는 Spent Bleaching Clay(SBC)를 육계사료의 에너지 공급원으로 활용 가능성을 구명하기 위하여 실시하였다. 부화 직후의 120수의 병아리(한협 3호)를4처리 3반복, 반복당 10수(암수 각각 5수씩)를 Control(T1) 사료에 SBC를 $2.0\%(T2),\;4.0\%(T3)$ 및 $6.0\%(T4)$ 첨가한 4처리로 배치하였다. 시험사료 급여전 1주일은 시판사료를 급여하였다. 4주간의 시험 기간동안 증체중 및 사료 섭취량은 T3 및 T4 처리구에서 증가하는 경향이 인정되었다. 사료효율은 T3구에서 개선되는 경향이 인정되었다. 가슴살 및 다리살에서 치방산 조성을 사료의 처리에 따른 효과는 인정되지 않았다. 육계 초기 및 후기 사료 급여시 모두, 사료중의 건물, 조단백질 및 조지방 이용율은 T4 처리구가 다른 처리구에 비해서 유의하게 감소하였으며(p<0.05), 대사에너지가도 T4 처리구가 다른 3구에 비해서 유의하게 저하하였다(p<0.05). 사료중의 조회분의 이용율은 사료의 처리에 따른 차이는 인정되지 않았다. 결론적으로 본 시험의 결과 육계사료에 $2\~4\%$의 SBC첨가는 육계의 성장 및 사료효율 개선의 가능성이 있음이 사료된다. This study was conducted to evaluate the feasibility of spent bleaching clay(SBC) as an energy resource for meat type chicks. A total of one hundred twenty 1-d old broiler chicks(Han-hyop, No. 3) were divided into four groups and each group was assigned to one of the following diets: 0(T1), 2.0(T2), 4.0(T3) and $6.0\%$ SBC(T4). Each treatment had 3 replications of 10 birds. Before feeding experimental diets, they were fed a commercial diet for a week Body weight gain and feed intake tended to increase in T3 and T4, respectively. Feed efficiency(feed intake/ gain) tended to decrease in T3 compared to other groups. Fatty acid composition of breast and thigh meat was not significantly affected by feeding SBC. Utilization of dry matter, energy, crude protein and crude fat was lower in T4 than in the other groups during both starter and finisher periods(p<0.05). Crude ash utilization was not significantly affected by feeding dietary SBC. These results indicate that broiler diets may be supplemented with 2 to $4\%$ SBC without adverse effect on growth.

This study was conducted to estimate the effects of genotype for chicken major histocompatibility complex (MHC) B-LB genes on economic traits. To detect polymorphism, 400 bp fragments of MHC B-LB genes were obtained and sequenced. After digestions using restriction enzyme Hea III, two restriction enzyme sites were observed. There were two mutations at position 427 and 651 those were decided as Type I and Type II, respectively. Using RFLP analyses, type I were genotyped to TT, TC and CC, and type II to MM, Mm and mm. The relatively higher TC genotype frequencies (0.8) of Type I and Mm genotype frequencies (0.88) of Type II were observed in Korean native chickens. The effects of the genotype on 150 days body weight trait were investigated by the associations of CC and Mm genotypes (P<0.05) in Korean native chickens. This result suggests that a significant association exists between the SNP and 150 days body weight. 본 연구는 한국 재래 닭의 유전적 특성을 분자표지를 이용하여 그 차이를 규명하고 초기성장에 미치는 영향을 분석하여 이를 이용한 재래닭의 개량을 목적으로 실시하였다. MHC class II B-LB 유전자 내의 염기변이체가 경제형질에 미치는 영향에 대하여 연구하였다. MHC class II B-LB유전자 내 400 bp 크기의 유전자를 증폭하여 염기서열 분석과 제한효소 처리를 이용한 다형성 분석을 실시하였다. 연구결과 두 개의 제한효소 절단지역이 발견되었으며 427 지역을 Type I 으로 651 지역은 Type II로 정하여 RFLP 분석을 실시하였다. Type I지역의 유전자형은 TT, TC, CC로 나타났으며, TypeII 지역의 유전자형은 MM, Mm, mm으로 나타났다. TC와 Mm 유전자형이 다른 유전자형과 비교하였을 때 한국재래 닭에서 높은 출현빈도를 보였다(0.8, 0.88). 유전자형이 한국 재래 닭의 150일령 체중에 미치는 영향을 분석한 결과 CC와 Mm 유전자형에서 통계적 유의성이 도출되었다 (P<0.05). 따라서 본 연구의 결과를 이용하여 한국 재래 닭의 유전적 특성을 규명할 수 있으며 초기 성장이 높은 성적을 나타내는 CC, Mm 유전자형을 개량에 이용하게 된다면 큰 효과를 얻을 수 있을 것으로 사료되어진다. 본 연구의 결과는 차후 한국 재래 닭의 과학적이고 지속적인 유전자원의 보존과 육종 전략에 있어 매우 유용하게 활용될 것으로 기대된다.
