尹衡植,申大休,崔載春,權重浩 慶北大學校 1982 論文集 Vol.33 No.-
This experiment was carried cut to investigate the relationship between nitrite and ascorbic acid contents in two kinds of tomato fruits namely, Bokwang, Suekwang, which were different distinguished in growth periods during culture. The results obtained were as follows. The nitrate content in two kinds of tomato fruits was relatively higher in Bokwang than Suekwang. It indicated high content as 5.8-12.5 ppm in flesh and 0.3-2.5 ppm in gelatinous pulp. In the beginning of growth period, nitrate content in flesh was 50-62.5ppm, and in the latter period was 21.3-38.4ppm. In the case of gelatinous pulp, it was decreased from 14.0-16.2ppm in the beginnig period to 9.3-10.7ppm in the latter period. In the case of nitite, there was no difference between two varieties. Nitrite content during growth increased from 0.15ppm to 0.21ppm in flesh and from 0.06ppm to 0.1ppm in gelatinous pulp. There was no difference between two varieties during growth in total ascorbic acid content and its concentration was 24.2-27.5mg in gelatinous pulp and was 13.8-18.6mg in flesh. The difference between two parts was about 10mg. In the changes of nitrate and nitrite content in tomato fruits, nitrate was decreased, whereas nitrite content was increased. In the changes of nitrate and ascorbic acid content in tomato fruits, nitrate content was decreased but that of ascorbic acid was increased slightly. In the changes of nitrite and ascorbic acid content in tomato fruits, nitrite content was increased and that of ascorbic acid was slightly increased too.

Thermal characteristics and the related physical properties of various domestic fibrous inorganic products were investigated and the results are as follows: 1) Quality of the domestic fiber glass and the products meet the standards designated under KS, JIS and ASTM, and the products showed the fiber diameter of 4-15μ, the density of 0,004-0.07g/㎤ and the thermal conductivity of 0.027-0.049kcal/m hr℃. 2) Insulating characteristics of the glass fiber products are closely related with the diameter of the glass fiber and the density of the products, are increased with smaller fiber diameter and higher density of the products, and showed the thermal conductivity mostly lower than 0.035kcal/m hr℃ at 20℃ (Mean temp.) 3) Domestic mineral fiber showed its fiber diameter of 5-11μ and the thermal conductivity of 0.025-0.37kcal/m hr ℃ at 20℃ (Mean temp.)

In sagittal split osteotomy as well as in vertical osteotomy for reduction of mandible, wire and bone screw osteosynthesis has been used. Relapse after sagittal split ramus osteotomy was well documented in many studies. Most of these studies, however, associated with cases which were fixed by transosseous wiring technique. For that reason, relapse rates after sagittal split osteotomy were reported to be reasonably high. Author studied of 20 patients who treated with bilateral · sagittal split ramus osteotomies. For reuction of mandible, stable osteosynthesis with tandem-screw was accompanied with IMF for 3 to 5 days. Author took the serial radiograph before and immediate post operative, postoperative 6 months. Author analysis 5 angular measurement and 4 linear measurement that was used to find out the amount of change in condyle position. According to the final analysis, minimal change was found in condylar position using thandem-screw fixation at postoperative 6 months. Resultly autuor s study indicates resistance against relapse with using tandem-screw fixation after sagittal split ramus osteotomy.

목적: 본 연구는 임신 제 1삼분기에 혈청 내 CA 125 수치가 갑자기 증가하는 경우 자연유산의 가능성이 높았다는 이전의 연구를 바탕으로 시작되었다. 이를 위하여 계류유산, 절박유산, 정상 임신부의 혈청 CA 125를 측정하였고 예후 인자로 가능한가를 분석하였다. 이 연구의 목적은 CA 125수치를 임신초기에 전향적으로 비교 분석하여 자연유산을 예측할 수 있는 검사법으로 가능한지를 판단하고 기초 자료로 이용하고자 시도 되었다. 연구 방법: 2001년 3월부터 2001년 9월까지 강남 차병원 산부인과 외래를 방문한 133명의 초기 임신부를 대상으로 하였으며 이 중 58명은 계류유산, 45명은 절박유산, 나머지 30명은 이전에 자궁내막증이나 난소의 종양이 없었던 정상 임신부였다. 이들의 임신 주수는 모두 6주에서 12주 사이였으며 모든 대상은 초음파로 확인하였고 각각의 대상에서 혈청내 CA 125를 검사 하였다. 결과: 각 연구군의 CA 125 평균은 계류유산이 72.9±102.0IU/ml였고, 절박유산은 46.6±37.9IU/ml였으며 정상임신부는 63.4±61.2IU/ml였다. 각 연구군 간에는 통계학적으로 큰 의미가 없었다. 결론: 본 연구 결과 혈청 CA 125 수치는 임신 초기에 자연 유산을 예측하는 예후인자로써 큰 의미가 없었으며 계류유산, 절박유산, 정상임신을 구별하는데도 큰 역할을 하지 못 하였다. Objective: The study was carried out to assess whether a sudden rise in the serum CA 125 level might predict spontaneous abortion in the first trimester. In the process, we assessed the clinical value of maternal CA 125 in patients with missed abortion and evaluate the prognostic significance of CA 125 in early normal pregnancies, threatened abortions. The purpose of this study was to prospectively compare serum CA 125 levels among women who abort in the first trimester, who experience threateneda bortion and who go through normal pregnancy. Methods: Between March 2001 and September 2001, a total of 133 patients were observed in the Department of Obstetrics and Gynecology at CHA Hospital. Fifty-eight with missed abortions, forty-five with threatened abortions and thirty normal pregnancies (no history of endometriosis or ovarian mass) were evaluated during gestational age 6 to 12 weeks and maternal serum samples were collected. All patients were sonographically assessed and CA 125 values were compared. Results: There was no statistically significant difference in the CA 125 levels between the spontaneous aborted patients and the patients without abortion: missed abortion, 72.9±102.0IU/ml (range 7.3-487.6); threatened abortion, 46.6±37.9IU/ml (range 13.9-206.1); normal pregnancy, 63.4±61.2IU/ml (range 13.8-62.8). Conclusion: Our study shows that serum CA 125 levels are not predictive of spontaneous abortion in the first trimester and failed to discriminate among missed abortions, threatened abortions, and normal pregnancies.
