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. In Group 2, the ratio of horizontal changes of hard tissue to soft tissue at 1/t Stmi, B/Si, Pog/SPog is 1.09, 1.11, 1.12 with postop. immediately, 0.92, 0.88, 0.99 with postop. 6 months. 3. In Group 3, the ratio of horizontal changes of hard tissue to soft tissue at A to Sn, 1 to Stms, B to Si, Pog to SPog is 1.15, 1.09, 1.15, 0.89, 1.05 with postop. immediately, 0.98, 0.94, 0.99, 0.90, 0.93 with pstop. 6 months.

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.

Milk protein genes and growth hormone gene have been targeted as modulator genes in growth and carcass traits. With the objectives to detect some correlation or genotypic effect of three known functional genes on economic performance, 19 sires and their 139 progenies of Hanwoo population were genotyped for κ-casein, β-lactoglobulin and growth hormone(GH) loci by polymerase chain reaction(PCR)-restriction fragment length polymorphism(RFLP) analysis. The growth traits, such as Body Weight and Average Daily Gain, and carcass traits of this population were analysed for possible association with three genetic loci. The frequency of B allele for κ-casein was 0.37 in Hanwoo and 0.23 for β-lactoglobulin. Among the analysed loci, κ-casein gene was found most significantly associated with the growth traits of economic importance. However, the ,β-lactoglobulin and GH did not show significant effects in Hanwoo. For carcass traits, effects of κ-casein were significant in EMA. Therefore, genotyping the candidate animals for κ-casein in Hanwoo can be of great benefit in selection programs.

This study was carried out to establish the optimal RAPD condition using, short oligonucleotide primers and then to compare the genetic characteristics of Korean Native Ogol Chicken with other breed of chicken, including WL, RIR, CN and KNBC. Each 5 individuals per breed were bled and DNA was extracted from collected blood. The primers used in this study were composed of 10 oligonucleotides of 50∼80% G+C content. The optimization on the primer annealing temperature, concentration of Mg ion, amount of template DNA was conducted. From initial 400 primers, 50 polymorphic primers between individuals of same or different breeds were selected. And finally, 10 primers showing highly polymorphic and reproducible pattern were selected and 49 polymorphic markers were counted for Band Sharing Coefficient estimation. Both KNOC and KNBC showed a high genetic homogeneity (0.862, 0.858) and RIR showed most homogeneous genetic composition {0.891). In the case of interbreed comparisons, both KNOC and KNBC showed the highest genetic similarity with CN (0.810, 0.835) and the least with WL (0.772, 0.782) than any other breeds. Therefore, the RAPD technique using short oligonucleotide sequences was useful for genetic analysis in chicken

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.

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.

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.
