沈相喆,閔庚隱,嚴在國,洪錫 경북대학교 1978 논문집 Vol.10 No.-

The reduction of nitro and nitroso compounds using tetracarbonylhydridoferrate-formaldehyde under mild conditions (at room temperature and then 60℃ under CO) gives the corresponding N, N-dimethylation via N-methylation in good to excellent yields. The reaction mechanism via immonium salt is assumed.

This study aimed at exploring what influence the trainers' leadership has on volley bell members' satisfaction, and in order to figure it out, the experiment of stratified random sampling was proceeded to 20 high schools teams, 7 university teams, and 5 industrial teams as objects for this study after selecting the population in the whole high schools, universities, and industrial players. Results was collected as follows. 1) Volley ball members' satisfaction according to the statistical characteristics of population It was shown that Members' satisfaction was estimated most high in male players for gender, industrial teams for team type, players under 3 years for playing experience and main players for playing position, However there is no significant difference among them. 2) Influence of leadership types on members' satisfaction Leadership classified as Training, Directing, Social Supporting, Democratic Behavior, Authoritative Behavior has positive correlation with the factors of satisfaction of members, such as task performance, social interaction, and coaching behavior, and has negative correlation with positive rewarding behaviors, Social Supporting among leadership types has much influence on players' task performance, and Training and Directing in social interaction and coaching behavior.

Bioequivalence of two flouxetine capsule, ProzacR (Lilly kora Ltd.) and LanclicR (Samsung Pharm. IND. Co.), was evalated according to the guideline of KFDA. Twenty four healthy male volunteers (21-26 years old) were divided into two groups and a randomized 2×2 cross-over study was employed. After 60mg of fluoxetine was orally administered, blood was taken at 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 24, 32, 48 and 72 hours after administration and just before administration. Plasma was analyzed for fluoxetine and internal standard (clomipramine) by a sensitive and validated HPLC assay. The pharmaco kinetic parameters (AUCt, Cmax and Tmax) wre calculated and ANOVA test was used for the statistical analysis of parameters. Differences in (AUCt, Cmax and Tmax between two capsules were -0.90, 3.46 and -14.08% respectively. All powers (1-β) for AUGt, Cmax and Tmax were more than 0.9. Detectable differences (Δ) and confidence interval were all less than ±20%. All the parameters above met the criteria of KFDA for bioequivalence and indicated that LanclicR capsules are bioequivalent to ProzacR capsules.

The present study investigated the relationship between the social problem solving ability of children and the language patterns of their mothers. The subjects included 193 nine year­olds (185 girls, 108 boys), and 230 twelve year­olds (115 girls, 115 boys). The instruments used were a language patterns test for the mother and IPA (Interpersonal Problem Solving Ability Test) for children. Major finding from this study were: ⑴ the correlation between the social problem solving ability of children and the language patterns of their mothers was not statistically significant, ⑵ the language patterns of the mothers were significantly different by child's sex; for boys, mother used more ordered language patterns and for girls, mothers used more ordered language patterns and for girls, mothers used more human­oriented language patterns, ⑶ the social problem solving ability of children were significantly different by child's age; 12­year­olds exhibited higher ability than 9­year­olds.

고려대학교 흉부외과에서는 심실보조장치 이식에서 흉골 재절개(re-sternotomy)에 따른 합병증과 사망률을 감소시키기 위하여 우측 개흉을 이용한 독자적인 수술법을 개발하였다 (KU technique). 다양한 동물모델과 사체실험 및 임상적용을 통해 안정성과 유용성을 확인하였으며, 향후 좌심 및 양심보조장치 이식에서 표준기법의 하나로 제안하고자 한다. We have developed a new surgical technique (KU technique) of right thoracotomy for cannulation of ventricular assist devices, which can lessen potential morbidity and morta1ity from re-sternotomy. The technique has been proved to be safe and efficient in various animal models, preclinical cadaver fitting test, and human application. We would like suggest KU technique as a part of standard in implantation of left ventricular or hi-ventricular assist devices.

저자들은 비호지킨씨 림프종 환자에서 항암 치료 후 질환의 진행성 병변과 감별을 요했던 우폐 중엽의 단발성 종괴를 흉강경하 생검으로 폐 효모균증을 확진하고 amphotericin B와 fluconazole로 치료한 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Non-Hodgkin's lymphoma is monoclonal expansion of malignant B or T cells. The immunocompromised status in this disease is accompanied by many infections. The cryptococcosis, caused by Cryptococcus neoformans, frequently occurs in leukemia, Hodgkin's disease, sarcoidosis, diabetes mellitus, tuberculosis, and long-term steroid-using patients. Recent increasing incidence of fungal infection could be due to the spread of AIDS and transplantation. We experienced one patient with lung mass in Non-Hodgkin's lymphoma after three cycles of chemotherapy, which could not be discriminated from the newly developed lymphoma mass. Cryptococcus neoformans was isolated from the lung tissue obtained by thoracoscopic biopsy. Herein we report this case with brief review of pertinent literature.

The authors investigated thoroughly the flotation characteristics of stibnite. The flotation behavior of this mineral was carried out by using modified hallimond tube with various xanthates as a collector and modifying agents such as copper sulphate, lead acetate, sodium sulfide, zinc sulphate, sodium cyanide, sodium sulfite and potassium dichromate. The main results obtained in this experiments are summarized as follows; (1) Stibnite shows that it has maximum floatability in pH range 4.0 to 8.0. (2) Stibnite is activated by copper sulphate and lead acetate. (3) Potassium dichromate is an effective depressing agents in stibnite-xanthate system in pH range 4.0 to 6.0. (4) In the pH range in which the zinc sulphate is preciptated by hydroxide, stibnite is depressed effectively (5) Stibnite is depressed by sodium sulfide in alkaline solution.

A half bridge type double resonant high frequency resonant inverter using PFM is described. This proposed inverter can reduce distribution of the switching current because of using the current of the serial resonant circuit to the input current of the parallel one. In the case of variable capacitance of the DC voltage source capacitor, the analysis of inverter circuit has generally described by using normalized parameter and operating characteristics has been evaluated in terms of switching frequency and parameters. Based on the characteristics value, a method of the circuit design is proposed. The theoretical results are in good agreement with the experimental ones. In the future, this proposed circuit is considerated to be useful for induction heating and discharge lamp.
