Clinicopathological study was made on 21 testis tumors that were obtained during a period of 12 years, from 1960 to 1971, at the Department of Pathology and Urology, Yonsei University. The 21 cases of testis tumor are consisted of 18 malignant and 3 benign tumors and are classified histologically into 7 seminomas, 8 embryonal carcinomas, 3 teratomas, 1 reticulum cell sarcoma, 1 rhabdomyosarcoma, and I gonadoblastoma. The mean age is 24.7 years, and 36.4 years in seminoma, 15 years in embryonal carcinoma, 17.7 years in teratoma, and 33 years in miscellaneous. The tumors occurred more frequently in the right than the left. There's no bilateral occurrence. The most frequent clinical complaint was painful palpable mass which were present in 6 cases out of 10 cases. One case of seminoma is arisen from intraabdominal testis which seems frequently to precipitate tumor occurrence. The other notable case is gonadoblastoma arisen in dysgenetic testis of true hermaphroditism.

Purpose: This study aimed to explore the relationship among score of theory course, score of practicum course and clinical practice ability by the course, Adult Health Nursing. Methods: A descriptive research was conducted using questionaries. Data were collected from September 25 to October 2, 2019. Participants were 67 nursing students at one university in Seoul on their junior year who have experienced clinical settings. The collected data were analyzed by t-test, ANOVA, Cohen’s Kappa, and Scheffe’s test using SPSS 25.0 version program. Results: Participants were given a quartile number from 1 to 4 respectively according to their scores of theory course those of practicum course. The total mean score of clinical practice ability was 3.61, with a perfect score of 5. The scores of theory course and practicum course showed slight correlation(Cohen’s Kappa=.168). However, significant correlation did not existed among score of theory course, score of practicum course and clinical practice ability. Conclusion: The result showed that score of theory course, score of practicum course and clinical practice ability have no significant correlation. However, its finding suggests the necessity of further research about various approach and new evaluation methods needed in order to improve nursing students’ competency.

A theoretical note on mode-I crack branching and kinking

Xie, Y.J.,Hu, X.Z.,Wang, X.H.,Chen, J.,Lee, K.Y. Pergamon Press ; Elsevier Science Ltd 2011 Engineering fracture mechanics Vol.78 No.6

An energy-based fracture mode has been derived for the mode-I crack branching and kinking. The classic J<SUB>i</SUB>-integral has been further explored by a new partial integral path and the analytical solution of the energy release rate for crack branching and kinking from a mode-I crack tip has been established. The crack branching/kinking angle has also been analytically derived. It shows that the Griffith's theorem and conservation law can be applied to both mode-I crack extension and mode-I crack branching and kinking. The branching mechanism for quasi-static mode-I crack has been theoretically investigated. The branching toughness and the K-based criterion for crack branching have been defined. The crack branching phenomena predicted by the present model are in well agreement with the experimental observations reported in the literatures.

Purpose: The purpose of this study is to verify the relationship between sociocultural attitudes towards appearance, appearance stress and eating disorders. Method: Sociocultural Attitudes Towards Appearance Questionnaire-4 revised which was translated to Korean measured sociocultural attitudes towards appearance and appearance stress measurement examined appearance stress. Korean Version of Eating Attitude Test-26 was used to measure eating disorders. 120 university students in a city took surveys from September 20 to October 8, 2019. Of the 120 questionnaires, 4 has insincere or incomplete responses and 116 questionnaires resulted in data. The questionnaires were investigated using statistical process of t-test, ANOVA, and Pearson's correlation coefficients using SPSS/Win 25.0 software package. Results: The average of KEAT-26 scores was 7.45 and the prevalence of eating disorders was 6.89% in the study. In eating disorders, there were significant differences according to subjective body image and diet experience. Eating disorders were positively correlated to sociocultural attitudes towards appearance (r=.21, p=.018) and appearance stress (r=.23, p=.006). Conclusion: This study verified the relationship between sociocultural attitudes towards appearance, appearance stress and eating disorders of university students, and expected to be supporting documents to develop programs for helping university students with eating disorders.

Effect of Si interlayer thickness and post-metallization annealing on Ge MOS capacitor on Ge-on-Si substrate

Yoo, O.S.,Oh, J.,Kang, C.Y.,Lee, B.H.,Han, I.S.,Choi, W.H.,Kwon, H.M.,Na, M.K.,Majhi, P.,Tseng, H.H.,Jammy, R.,Wang, J.S.,Lee, H.D. Elsevier Sequoia 2008 Materials science & engineering. B, Advanced funct Vol.154 No.-

We demonstrated the effect of post-metallization annealing and Si interlayer thickness on Ge MOS capacitor on Ge-on-Si substrate with HfO<SUB>2</SUB>/TaN. Ge outdiffusion and oxygen interdiffusion were completely suppressed by thick Si interfacial layer. As a result, formation of insufficient low-k Ge oxides was effectively inhibited. It is confirmed that gate current of Si passivated Ge MOS was decreased by Si IL and decrease of gate current, J<SUB>g</SUB> is saturated after Si IL of 2nm. It was also observed that when Si IL is thick enough to restrict Ge outdiffusion, increase of J<SUB>g</SUB> is not due to the temperature-induced Ge outdiffusion but due to the partial crystallization of HfO<SUB>2</SUB> at higher annealing temperature.

알루미늄 기지에 30% 탄화규소(SiC)가 보강된 금속수지 복합재료에 대한 방전가공 실험을 가공조건들의 변화에 따라 진행하였다. 드릴가공시 높은 탄화규소의 보강 때문에 밑면에서 취성파괴가 발생하였다. 특성 평가로 전류와 듀티팩터의 변화에 따른 공막물제거 속도를 측정하였으면, 표면형상을 표면거칠기와 전자현미경 사진으로 평가하였다. 전류가 증가될수록 공박물제거속도는 증가하는 경향을 나타내나, 듀티팩터의 변화에 따라 0.45까지는 증가하난 그 이상에서는 휴지시간의 상대적인 감소로 칩방출 시간이 충분하지 못하여 큰 면화가 없었다. 최대 표면 거칠기는 전류 및 듀티팩터의 변화에 따라 다소 증가하는 경향을 나타내었으며, 방전가공은 전자 현미경 사진들로 관찰하여 보면 용융 후 재융착 과정이 있는 것으로 나타났다. Electrical Discharge Machining (EDM) of Metal Matrix Composite(MMC) material with 30% Sic particulate based on A1 matrix was conducted for various conditions. When drilling process was executed for small holes, brittle fracture was found near the bottom surface due to the higher Sic percentage. Material Removal Rate(MRR) was examined for different conditions and the surface morphology was evaluated by surface roughness parameters and Scanning Electron Microscopy (SEM) photographs. The higher the current is, the more MRR was obtained but the MRR was increased up to 0.45 of duty factor and decreased after that. The maximum surface roughness of EDMed surface was slightly changed with increased pulse current and increased with duty factor. The SEM photographs of EDMed surface showed recast region after melting.

Amoxicillin의 요로감염증에대한 임상효과

이무상,권성원,이진무,왕종순 中央醫學社 1976 中央醫學 Vol.31 No.4

Amoxicillin (a-amino-p-hydroxybenzylpenicillin) is a new orally administered,semisynthetic penicillin structurally related to ampicillin. Also, it has been known that amoxicillin has an antibacterial spectrum similar to that of ampicillin with more increased gastrointestinal absorption and easy urinary excretion. Authors evaluated the in-vitro antibacterial activity of amoxocillin and ampicillin against several micro-organisms and used amoxicillin in the urinary tract infection clinically. In vitro the level of activity of amoxicillin is generally similar to that of ampicillin. With 1.5gm of amoxicillin a day in divided doses for 7-10 days 30 cases of acute urinary infection were treated, and then 85% was cured clinically and bacteriologically. In uncomplicated, gonorrheal infections amoxicillin 3.0gm and ampicillin 3.5gm plus probenecid 1.0gm in a single dose are effective similarly with over than 90% of cure rate. We consider this drug to be one of the most effective antibiotics in the urinary tract infections, especially in uncomplicated gonorrheal infections.
