융비술시 실리콘 고무는 다루기 쉽고 조직 반응이 적어 현대 많이 돌출의 합병증이 생길 수 있다. 저자등은 이러한 실리콘의 단점을 보완할 수 있는 goretex를 사용하여 융비술을 시행하고 비첨에 대해서 자가연골을 이식하여 만족할 만한 결과를 얻었기에 goretex가 안면부 연조직의 증강을 위한 이식재료로 적합하다고 생각되어 문헌고찰과 함께 보고하는 바이다. Many different materials have been used to provide augmentation of the nasal dorsum. this include both autogenous and homogenous materials,as well as allografts. Silicone among the artificial materials has been most widely used. The silicone has some advantages and disadvantages. Goretex(expanded polytetra-fluoroethylene) which has widely used in vascular surgery and abdominal surgery can be used for facial soft tissue augmentation. The author presemts 2 cases of nasal augmentaion using goretex with literature review.

Chromium occurs naturally in the earth's crust as well as in air, surface, and ground water. However, chromium is released to the environment in much larger amounts as a result of human activities. Hexavalent chromium, Cr(Ⅵ), is very soluble in water in natural environment and very toxic, carcinogenic, and mutagenic in animal and man. On the other hand trivalent chromium, Cr(Ⅲ), is less toxic and less soluble and thus is a lesser problem. This study has been carried out in order to reduce toxicity of Cr(Ⅵ) by an Escherichia coli strain. After adding E. Coli., the results were obtained from concentration of total Cr, Cr(Ⅵ). Cr(Ⅲ), pH, turbidity, and VSS in aerobic condition was summarized as follows : After 48hr aerobic condition in experiment of synthetic wastewater, the reduction rate of Cr(Ⅵ) was 20%. Also, the reduction rate of Cr(Ⅵ) was 60% in experiment of raw wastewater.

멜라닌 색소의 생합성 과정에 관여하는 것으로 알려져 있는 효소 및 관련 인자와의 상관성을 검토하기 위하여 자연산 정상넙치와 양식산 백화넙치의 肉質과 表皮, 미립자 사료와 생물먹이인 Artemia 및 Rotifer에 대하여 단백질의 함량, 멜라닌 색소생성에 고나여하는 효소의 활성, 아미노산 조성 및 비타민A와 C의 함량을 비교하였다. 정상넙치表皮는 肉質에 비하여 단백질의 함량이 높았으나, 백화넙치인 경우는 대체로 비슷한 값이었다. 사료중의 단백질 함량은 미립자 사료 중 C1이 가장 높았다. catechal oxidase의 활성은 기질과 조효소 농도의 증가와 더불러 증가하였으며, 백화 유무에 관계없이 거의유사한 값으로 나타났다. 그리고 L-dopa oxidase활성도 동일한 결과였다. 정상넙치의 유리아미노산 함량은 백화개체에 비하여 높았으며, 表皮의 경우는 정상넙치가 백화너치에 비하여 7.5배 가량 높은 값을 나타내었다. 필수아미노산의 조성으로 비교했을 때, 미립자 사료는 Artemia와 Rotifer보다 우수한 단백질원이었다. 그리고 정상넙치의 함활아미노산의 함유량은 백화넙치의 6.3배에 달하였다. 비타민A는 정상 및 백화넙치의 肉質과 表皮에서 검출되지 않았으나 비타민C는 정상인 접치表皮가 백화넙치 表皮에 비해 약 7.8배였으며, 미립자 사료는 100.83mg/100ㅎ으로서 사료 중 가장 높았다. 따라서 넙치表皮의 멜라닌색소의 생성에는 기질인 방향족 아미노산과 함황아미노산이 큰 영향을 미치는 것으로 판단되었다. The albinic phenomenon of flat-fish (Paralichthys olivaceus) was investigated by measuring protein content, tyrosinase activity, amino acid composition, and contents of vitamin A and C. These materials in the flat-fish feed-stuff were also tested. The amount of skin protein was higher than that of muscle in normal flat-fish. Catechol and L-dopa oxidase activity did not differ between normal and albinic flat-fish. The free amino acid of skin in normal flat-fish was 7.5 times that in albinic one. Sulfur-containing amino acid in normal flat-fish was also 6.3 times that in albinic ones. Vitamin A was not detected in both of flat-fish. The content of vitamin C in normal flat-fish was 7.8 times that in albinic one. The contents of protein, sulfur-containing amino acid and Vitamin C in micro-encapsulated feed (one commercial feed in Japan) were the highest among the feed-stuff used in this experiment. The melanin formation of flat-fish skin was affected by substrates such as aromatic amino acid and cofactor such as sulfur amino acid.

The results of radiographic study of healing of fractured mandible are often inconsistent with clinical evaluation of bone healing pattern of it. In addition, there is inconsistency between radiographic studies. We think if such inconsistency is resolved, clinical assessment combined with radiologic evidence can be used to guide to more accurate clinical management. The purpose of this study is to evaluate radiological healing pattern of mandible, and to apply its result to clinical use. Panoramic view was used to analyze the change of radiographic finding in 35 patients (27 male, 8 female, ranging 17 to 53 years old) treated for mandibular fracture at the department of oral & maxillofacial surgery, SNUH in the period 1991 to 1998, Patients are all treated by rigid internal fixation using monocortical miniplate. Within 9 weeks, no change is observed at fracture site. Osteogenic change is observed at various time interval (3 to 21 weeks). We have found radiographic change of healing is observed 4 to 6 weeks later to clinical healing, According to this result, we recommend radiographic follow-up at 4 week, 10 week, 10 month.

This paper has been studied to eliminate the wear of tire on the solid axle type of an automotive. The heavy tracks, different from passenger cars, have a front axle which consists of a solid axle in a shape of I-beam. Therefore, it is difficult to change the fixed angle of camber and king pin once they are assembled. This study has introduced a suitable method to remove the uneven wear of tire by combination of camber and king pin angle at the stage of design. Parametric optimization has been carried out by setting the optimum characteristics for static and dynamic analysis. The static characteristics represents a condition where the tire and ground makes a perpendicular angle, which makes the ground camber to be zero. The optimal dynamic condition is to minimize the lateral force between the tire and ground in dynamic simulations.
