이재덕,김성도 東亞大學校附設基礎科學硏究所 2002 基礎科學硏究論文集 Vol.19 No.1

Impedance methode를 이용하여 빠른 산화-환원 속도를 가지는 [(NH_3)_4Ru(dpp)]^2+의 전극반응속도를 측정하고 검토하였다. 이 방법으로 구한 이 착이온의 확산계수, D 는 6.11×10^-7 cm^2/sec 이고 표준전극환원 반응속도 상수, k_s는 0.015 cm/sec 이었다. 이는 전형적인 빠른 전극반응 속도를 가지는 ferrocene에 대한 값, 0.154cm/sec의 1/10에 해당되며, 이 결과는 광 에너지 이용의 기초자료로 이용될 것이다. The electrochemical reaction rate constant of [(NH_3)_4Ru(dpp)]^2+ was examined and discussed by the impedance spectroscopic method (dpp=2,3-bis(2-pyridyl)pyrazine). The diffusion coefficient, D of the [(NH_3)_4Ru(dpp)]^2+ was determined as 6.11×10^-7 cm^2/sec and the electrochemical reaction rate constant, k_s was determined as 0.015 cm/sec. The k_s value was 1/10 of that ferrocene which has typically rapid electrode rate constant, and the result could be used as a basic reference for the reservation and application of light energy.

윌라 캐더 작품에 나타난 에코페미니즘 : O Pioneers!와 My Antonia O Pioneers!, My Antonia

장재덕 경운대학교 산업기술연구소 2001 産業技術硏究論文誌 Vol.3 No.2(A)

Willa Cather's works have been studied in various ways for pas decades. Some say her works are the frontier's novels and others say lesbian and feminism novels. In this thesis, however, I have dealt Cather's works, O Pioneers! and My A′ntonia in an ecofeministic point of view. Nowadays, of course, the ecofeminism is different from the authors. They usually described the rights of the women and the equation of the man and woman and how to struggle to get their natural rights. In this paper, I mainly followed point of view of Vandana Shiva, and Maria Mies. They think of the earth as Mother. They insisted that we have to take good care of the natural order and environment problems when we develop the earth. The mother is the resource of all the activities in human life. We can get all the energy from the fully understanding of the natural order an rules. The friendlier we treat the earth, the better life we can get. In O Pioneers! and My A′ntonia, I can analyse the facts that two main characters in both works perform their lives keeping the rules and orders of the nature. If they ignored the natural order and the rules, they usually had hard time and difficulties in their live. We can recognize that Alexandra in O Pioneers! and Antonia in My A′ntonia lived very difficult lives but their effort for the earning their livings was very hard and desperate. In case of their forgetting the nature and the earth for the time being or staying away from the country, their lives with their family were even worse than ever. If they kept the natural law and energetic powerful will came from the earth in their minds, their lives would be changed. In that point, we can understand the relationships between human beings and the earth. Also we perceived how the earth in our life, effects us.

『방황하는 부인』에 나타난 에코페미니즘의 거부와 파멸 : A Lost Lady

장재덕 경운대학교 산업기술연구소 2002 産業技術硏究論文誌 Vol.4 No.2

The works of willa Cather have been studied from many points of view by critics and researchers. Cather's descriptions of the land and of the Great Plains are especially well-known to researchers and her readers. Most, of course, never fail to acknowledge Cather's vivid portrayal of the frontier and pioneer spirit in her masterpieces O Pioneers! and My A´ntonia. The stories and characters she wrote about were fundamentally connected with natural factors and matters. Nowadays, there is a highly significant tendency in our daily lives: ecology is applied to every place and every moment in order to provide better environments for human lives and human beings. Thus in this thesis, I examine Cather's novels from a specified point of view, ecofeminism. I try to show the bad effects from the betrayals of ecofeminism principles in A Lost Lady. I discuss how Cather treats characters who go against ecofeminist principles. I present this notion with examples from A Lost Lady. Captain Forrester in A Lost Lady lived tragic lives. The lives of Forrester underwent rapid changes. When he of his wife pursued money, their lives lost value. The pursuits for gold and moral corruptions of his wife accelerated the degradation of captain Forrester. Money, the idol of the modern world, changed their lives. The ultimate significance of this thesis is to point out that Cather's writings give us a chance to find ourselves, to think about the way we conduct our lives in relation to others and to the natural world. All of us must find ways to enhance our lives in harmony with the natural environment in which we live. We can then positively alter the course of human history.

남덕현,이한경,박재우,김명준 龍仁大學校 2000 용인대학교 논문집 Vol.18 No.-

The purpose of this study was to evaluate the improvement of the cervical extensor muscles strength in a 103 patients with laser discectomy using Medex program. 103 Patients was divide into 3 Groups, Study group of 40 patients (M=17, F=23), Control Group of 32 patients (M=17, F=15), Normal Group of 31 patients(M= 19, F= 12) Study and Control group was the patient of Laser discectomy on the cervical disc. Study Group was trained with Medx exercise program for the cervical muscles for 12 weeks after 1 month from cervical Laser discectomy. Control Group was rest at home for 12 weeks after the therapeutic exercise program. Normal group was good condition normal persons in cervical and Lumber spine without lesion, 31 persons was tested cervical extension muscle strength before and after 12 weeks. The results of this study were as follows ; 1. In initial muscle strength. The male was found 34275.95 8546.55(n=20) in study croup, 32279.66 3965.43(n=18) in control group, 54297.42 721,39(n=19) in Normal group. The female was found 24445.25 7360.80(n=20) in study group, 25125.64 4463.65(n=14) in control group, 42829 9649.62(n=12) in normal group. Therefore in a study and control group, It was found that the subjects have similar muscle strength after the 12 weeks with no difference. 2. Between three group, after 12 weeks, improvement of male muscle strength was found 50142.29 13017.37(n= 17, study group), 38973.44 7424.36 (n=18, control group), 55774.41 9268.05 (n=17, Normal group) in male. And improvement of female muscle strength was found 40227.80 6062.89(n= 15, study group), 29777.78 10647.34 (n=14, control group). As a result, muscle strength after 12weeks, it was found a little difference cervical extension muscle strength in control group without therapeutic Exercise program. But study group there was a much difference. 3. Study group was statistically significant difference(P<.05, n=40) after 12weeks. And control group was statistically significant difference, too(P<.05, n=32). But in real value, improvement of muscle strength was 50% improvement in study group more than 19% in control group. 4. After 12weeks in a study and control group, Pain scale shows statistically significant difference in study group than control group(P<.05). 5. After 12Wks, Cervical ROM was increased in a study and control group, each other. In a Study group it was found that there was an increase ROM more than control group(Flexion position; study/control G. =124.6 /118.8, Extension position: =1.68 /8.4, ROM; full Extension=0, full Flexion= 126). In conclusion, After 1 month laser discectomy in cervical HNP, The study group with procedure of Medx therapeutic exercise program was statistically significant increased cervical extension muscle strength more than control group with no therapeutic exercise program. And compared with control group, Study group shows decrease in a pain scale as well as the ROM of cervical mobility. Therefore, during 12 weeks Medx therapeutic Exercise in the cervical spine was effective in cervical muscle strength and for the pain, limited ROM, and dysfunction. And the early recurrent and prevention is positively necessary scientific controlled therapeutic exercise program.
