金炯九,崔虎容,李顯式 최신의학사 1968 最新醫學 Vol.11 No.12
Leiomyosarcoma of the uterus is far less common lesion. The diagnosis of, this lesion is rarely made preoperatively, because the symptoms and physical findings are attributed to the myomata. A case of Leiomyosarco ma combined with bilateral ovarian cysts found postoperatively is presented with a brief review of literature available.

ObjectivesThis study was designed to investigate the effects of fermented soybean upon anti‐inflammation, cytotoxicity, antioxidant and intestinal mucousmembrane permeability by measuring the cell viability, NO (nitric oxide) production, DPPH, Polyphenol, HRP and TEER in cells like Raw 264.7and HCT 116 using fermented soybean. MethodsRaw 264.7 cell and HCT 166 cell were used in this study. And fermented soybean powders were used for the experimental group and soybeanpowders for the control group. There was inflammation response upon using lipopolysaccharide(LPS). Fermented soybean powders and soybeanpowders were in a respectively different dose added to the cells with LPS. MTT assay, NO, DPPH and Polyphenol measurement, TEER, HRPwere conducted for each cell. The results of this study were presented in mean and standard deviation. Results1. In Raw 254.7 cells added with 100μl/ml unfermented soybean powders, 104.95% higher than 62.59% was measured. In Raw 254.7 cells addedwith 100μl/ml fermented soybean powders, there was 74.90% measured higher than 62.59%, which was a significant result. 2. By a gradual increase of unfermented soybean powders like 0.1μl/ml, 1.0μl/ml, 10μl/ml, 100μl/ml, the measured NO were also graduallydecreased 53.12μM, 47.57μM, 37.02μM, 28.16μM. In case of cells added with fermented soybean powders, 43.95μM NO was measuredin 0.1μl/ml which is significant, and in other cases, mostly measured over 56.72μM. 3. It was inferred that fermented soybean powders have anti‐inflammatory effects of maintaining intestinal mucous membrane permeability becausethe measured values of cells in both groups were all higher than 133.62Ω measured of cells added with only LPS. And measured valuesof cells in both groups were all lower than 2.26 measured of cells added with only LPS. 4. In case of experiment DPPH and polyphenol measurement, fermented group was all higher than unfermented group. ConclusionFrom the results of conducting MTT assay, NO measurement, and TEER, HRP by using cells Raw 264.7 and HCT‐116, even though there wasno significance in the correlation between cytotoxicity, anti‐inflammatory effects, both unfermented soybean powders and fermented soybean powderswere shown to have intestinal mucous membrane permeability improvement effects. This effects could be applicable for autoimmune diseases,chronic inflammatory diseases and so additional studies are expected in the future. From the results of conducting DPPH, Polyphenol measurement,Fermented soybean may be useful as potential antioxidant.

기하학적. 재료적 비선형성을 갖는 중첩된 판 스프링의 특성해석에 관한 연구
김형구,임정식,김일곤,손동성 대한기계학회 1990 대한기계학회논문집 Vol.14 No.1
본 연구에서는 일반적인 셸 요소에 대해 von Mises의 항복조건에 입각한 탄소 성 구성방정식과 total Lagrangian식을 바탕으로한 비선형 해석이론에 Lagrange Mult- iplier식을 이용한 구속조건(constraints)을 도입하여, 중첩된 비선형 구조물이 갖고 있는 제반 비선형성을 고려할 수 있도록 수식화하였으며, 이를 엄밀해를 구할 수 있는 두개의 외팔보가 중첩된 경우에 적용하여 엄밀해와 비교하였으며, 또한 실제적으로 국 산 핵연료 집합체에 사용되는 각 홀드다운 스프링 집합체에 대한 특성 해석을 수행하 여 그 결과를 실험치와 비교하여 그 비교치가 근사함을 보임으로써 본 방법의 신뢰성 과 효용성을 보였다. A general analysis method is proposed for analysis of the superposed structures with geometric and material nonlinearities. It is presumed that no friction occurs between structures. It utilizes a shell element for the geometric and material nonlinearities and imposes various deformation constraints for the contact and interaction between structures. To show the reliability and effectiveness of this method, superposed cantilevers for which exact solutions can be obtained and holddown spring assemblies which are now used in PWR reactors are chosen as analysis models. The results of analyses were compared with exact solution in the case of cantilevers and with test results in the case of holddown spring assemblies. The analysis results obtained by this method showed good agreement with the reference values.
