일제하ㆍ미군정기 韓昇寅의 政治活動과 經濟認識

吳鎭錫 연세대학교 경제연구소 2001 延世經濟硏究 Vol.8 No.1

본고는 1920년대부터 1930년대 초반에 걸쳐 일본의 明治大學과 미국의 풀러톤, 미주리, 콜롬비아 대학 등에서 修學하였고, 미국유학중에는 興士團에서 그리고 귀국해서는 同友會에서 활약하였으며, 協成實業學校 敎師, 和信百貨店 社員을 거쳐, 解放後에는 美軍政의 商務部 商務局長에 발탁되어 남한의 資本主義 國家建設에 일조했던 韓昇寅 의 정치활동과 경제의식의 형성과정, 내용 등을 검토한 글이다. 그동안 이 시기의 經濟學者, 經濟評論家들을 대상으로 한 경제사상사연구가 활발히 진행되어 왔지만, 社會主義 經濟學者들과 이른바 中間派 진영 논자들의 경제사상해명에는 일정한 성과를 거두었음에도 불구하고 정작 구미유학을 통해 근대 자본주의 경제학을 체득하고 귀국하여 민족ㆍ자본주의 진영에서 활동하면서 해방후 남한 자본주의 사회의 주역이 되었던 지식인들을 사례연구로서 검토한 작업은 드물었다. 그러한 점에서 본고는 그간의 연구사적 공백을 일부이나마 메울 수 있으리라고 생각한다.

The most important factor in the beauty of the face is the harmony of the facial skeleton and soft tissue. The postoperative result is not always satisfying after only classic soft tissue surgery. The reason for dissatisfaction is disharmony of the facial skeleton. Recently, the development of maxillofacial surgical techniques enable disharmony of the facial skeleton to be successfully corrected. The authors have had experience with 33 cases of congenital and acquired facial deformities, from March of 1986 to February of 1989, and have followed them from 6 months to 2 years. We used an intraoral approach in most cases and got good results. There were four wound disruptions which were treated conservatively and resolved without sequelae.

신경회로망을 이용한 SRM의 토오크맥동 저감제어

안진우,오석규 慶星大學校 1998 論文集 Vol.19 No.1

This paper proposes a control scheme reducing the torque ripple of SRM using ANN(Artificial Neural Network). The torque of SRM depends on phase current and the rate of inductance variation. But the latter is nonlinearly changed according to phase current, which makes a difficulty to control the instantaneous torque. Therefore learned inductance of SRM using ANN that is known to treat nonlinear system recently, is used to predict instantaneous torque and to reduce torque ripple in SR drives.

Myelodysplastic syndrome(MDS) is a group of acquired conditions characterized by progressive bone marrow failure associated with normocellular or hypercellular bone marrow that cannot be attributed to nutritional deficiency, chronic infection, or other chronic systemic illness, and cannot be reversed by the successful treatment of those conditions. Whereas the cases of secondary MDS occur at all ages, primary MDS is essentially a disease of elderly, though no age group is exempt and predomonant in men. The MDS is fundamentally clonal disorders at the level of the haemopoietic totipotent stem cell. Clinically, they are characterized by varing degrees of peripheral cytopenia(s) with morphological and functional abnormalities of blood elements. We have experienced two unrelated pediatric cases, who showed pancytopenia on admission and the characteristic marrow findings of MDS. The first case, a 12 months-old girl, showed increased reticulin with abnormal localization of immature precursor cells(ALIP) in her bone marrow, in addition to dysplastic features such as bi-and multi-nucleation of late normoblasts and internuclear bridging. She also showed 22% of blasts in her bone marrow cells thus classified in the category of RAEB-t after FAB classification. Also found were a chromosomal abnormality namely 46 XX t(14q21q), which was an unusual one. Her family brought her home and, 4 month later, she deceased. The second case, a 12 year-old boy, showed pancytopenia with Pseudo-Pelger-Huet anomaly in neutrophils but no blasts in the peripheral blood. Bone marrow of this case also showed the picture of dyserythropoiesis with binuclearity, internuclear bridging, nuclear fragments, multinuclearity of late normoblasts, in addition to megaloblastoid change in the normoblasts and increased mitosis in granulocytic series. No chromosomal abnormality was found. Classified as RA after FAB classification of MDS. Showed good response to conservative management for anemia for more than one year.

The Purpose of this study was to investigate the effect of exercise intensity on blood glucose and insulin levels in diabetic rats with alloxan. Twenty sprague-dawley male rats were assigned to power training groups(n=10) and endurance training groups(n=10). Diabetes was induced by single injection of alloxan(50 mg/kg B.W) Blood glucose and insulin were determined every week for 4-weeks. The conclusion of this study follows as below: 1) There was significantly different on blood glucose levels in two groups. 2) There was significantly different on insulin levels in two groups These results suggest that proper exercise intensity in diabetic rats can significantly decrease blood glucose and insulin level and make good glycemic control. In conclusion, it has been found that regular prolonged endurance training with diabetic rats, improves insulin and blood glucose.
