Objective: The purpose of this study is to compare the effects of Dong-si acupuncture therapy and General acupuncture therapy for the patients with acute ankle sprain. Methods : This study has been carried out for 60 cases of ankle sprain patients who have visited Dong-Seo Oriental medical Hospital from May 1, 2002 to September 30, 2002. We have treated 30 cases of them by Dong-si acupuncture therapy and the other 30 cases by General acupuncture therapy. And we have compared those two group. Results : 1. There was no significant difference at the treatment period and the number of treatment times in comparing two groups. 2. The number of treatment times for good effect is that : Dong-si took $1.57{\pm}0.85$ times and General acupuncture therapy took $2.15{\pm}0.96$ times. And we have found that the effect of Dong-si acupuncture therapy is faster than the other.

A study on the indirect fluorescent antibody test(IFAT) using the sectioned egg antigen in the liver of white rats was performed. The antigen used was prepared in 6~8㎛ thickness by frozen section at -20℃ of nonembryonated C. hepatica eggs deposited in the liver tissue after 6 weeks of infection. Fluorescein isothiocyanate (FITC) conjugated anti-rat IgG (Goat) was diluted by 64 fold in phosphate buffered saline (PBS, pH 7.2) and counterstaining with a 1/10,000 solution of Evans blue was effected while the fluorescent conjugate is acting by diluting the labelled antiglobulin in the Evans blue solution instead of in the PBS. A total of 22 white rats (B.W. 150g) was divided into 2 groups (A, B) and 200 and 2,000 embryonated eggs were infected orally. All rats were bled by retro-orbital puncture prior to infection and weeks of 1, 3, 5, 7, 9 and 13 after infection. As negative control sera, 60 normal rats were used. Eggs for infection were cultured at room temparature for 4~5 weeks in 0.5% formalin. IFAT was processed by the modified method of Wilson et al. (1974). The results obtained were summarized as follows; 1. The localization of antigens in frozen section of non-embryonated eggs of C. hepatica detected by IFAT was seen on the inner membrane of egg shell. 2. IgG titers detected by IFAT rapidly increased in 3 weeks after infection, thereafter the titers were kept until 5 weeks and gradually decreased in 7 weeks to 9 weeks, then converted into normal by 13 weeks. 3. IgG titers distributed from 16 to 1,024 and showed highest titers in 3 and 5 weeks. 4. Mean titers of 3, 5, 7, 9 weeks after infection were higher in group B than in group A.

펄스 SiH₄플라즈마 화학기상증착 공정에서 입자 성장에 대한 펄스 변조의 영향
김동주,김교선 강원대학교 산업기술연구소 2006 産業技術硏究 Vol.26 No.B
We analyzed systematically particle growth in the pulsed SiH_4 plasmas by a numerical method and investigated the effects of pulse modulations (pulse frequencics, duty ratios) on the particle growth. We considered effects of particle charging on the particle growth by coagulation during plasma-on. During plasma-on (t_(on)), the particle size distribution in plasma reactor becomes bimodal (small sized and large sized particles groups). During plasma-off (t_(off)), there is a single mode of large sized particles which is widely dispersed in the particle size distribution. During plasma on, the large sized particles grows more quickly by fast coagulation between small and large sized particles than during plasma-off. As the pulse frequency decreases, or as the duty ratio increases, t_(on) increases and the large sized particles grow taster. On the basis of these results, the pulsed plasma process can be a good method to suppress efficiently the generation and growth of particles in SiH_(4) PCVD process. This systematical analysis can be applied to design a pulsed plasma process for the preparation of high quality thin films.
辯證法劇 考察 : Max Frisch의 변증법극을 중심으로
김동선 건국대학교 중원인문연구소 1997 중원인문논총 Vol.16 No.-
Frisch und Durrenmatt Werden im allgemeinen als Nachfolger des Brechtschen Parabeltheaters bezeichnet. Doch der Einfluβ, den Bert Brecht auf das dramatische Werk von Max Frisch ausgeubt hat, laβt sich nicht so eindeutig als Brecht Nachfolge definieren, wie es bei Versuchen, Frisch literahitorisch einzuordnen, immer wieder getan worden ist. Max Frisch hat im zahlreichen. Aufsatzen uber seine Begegnungen mit dem Dichter keinen Zwiefel daruber gelassen, daβ er von Brecht sehr viel gelemt hat und sich in der formlaen Entwichlung seiner Dramen an ihm orientiert, doch seine Dichtung bedeutet nicht Nachfolge Brechts, sondern eine kritische Auseinandersetzung mit dessen Werk. Brecht und Frisch sind Stuckschreiber des dialektischen Theaters, das einen lehrhaftigen zwech behalt, der auf die Veranderung des Menschen und die Reform der Gesellschaft zielt. In ihren Stucken gibt es Gleichheiten und auch Unterschieheiten. Die kritische Darstellung des epischen Theaters entspricht im Grunde einer soziapolitischen Analyse. Es wendet die Methode der Dialektik auf das Drama an. Die Buhne selbst darf also theoretisch nur der Spannung von These und Antithese und Ausdruck verleihen, denn die letzte Erkenntnis und Verwirklichung der Synthese bleibt ja dem Zuschauer vorgehalten. Dadurch mussen Brecht und Frisch das soziale Bewuβtsein des Betrachters ert wecken. Hiermit sei es auch betrachtenswert, daβ die beiden Dichter von der Belehrbarkeit des dialektischen Theaters keiner gleichen Meinung sind, d. h. Brecht ist darauf ziemlich optimistisch, daβ der Mensch durch diese Buhnentechnik uberzeugt wird. Frisch ist doch dagegen. Er hat einmal wie folgt erwahnt, man ist geschlagen, aber nicht uberzeugt wird. Frisch ist doch dagegen. Er hat einmal wie folgt erwahnt, man ist geschlagen, aber nicht uberzeugt. Also ist er auf die Wirkung des Parabelstuckes sehr" pessimistisch. Es sei erachtenswert, daβ die Meinungsverschiedenheit der beiden Dichter darauf deruht, daβ Frisch eigentlich ein Suchender der Asthelik ist und Brecht Marxist ist, der die Reform der Wirklichkeit heftig behauptet.
최소자승법을 이용한 다수 베타 방출 핵종 혼합물의 방사능 분석

베타선 스펙트럼의 최대 에너지가 확실하게 구별되는 2개의 핵종만을 포함하는 혼합시료의 경우에는 최대 에너지가 다르다는 점을 이용하여 손쉽게 각 핵종의 방사능값을 측정할 수 있다. 그러나 3개 이상의 베타 방출 핵종이 포함된 혼합물에 대해서는 각 핵종의 스펙트럼이 서로 겹치기 때문에 이러한 방법으로 구해진 방사능값은 신뢰도가 떨어지게 된다. 따라서, 본 연구에서는 최소자승법을 이용하여 혼합물의 중첩된 베타선 스펙트럼을 각각 분리 정량분석할 수 있는 밥법을 제시하였다. 또한, 실제로 4개의 베타 방출 핵종 ^3H, ^14C, ^16Cl, 90Sr)이 혼합된 사료를 조제하여 본 분석법을 검증한 결과 최고치 Reference value)와 분석치가 7% 이내에서 잘 일치함을 보였다. It is possible to count and perform quench correction on two β-label samples so long as the maximum β-energies are sufficiently different. However, when the coventional technique is applied to the radioassay of a mixture of more than three nuclides, the reliability of the activiteis determined is considerably reduced, resulting from the large overlapping of liquid scintillation pulse height distributions of ezch nuclide. A technique that allows the activities of multiple β-labeled samples to be radioassayed was proposed by using the least square method. The technique was applied to mixture samples of ^3H, ^14C, ^16Cl, and ^90Sr. The analytical values were in good agreement with the reference values within 7% relstive error.
