이상엽,주영은,이만기 啓明大學校 醫科大學 1983 계명의대학술지 Vol.2 No.1

마우스 비임신적출자궁 5예와 임신전기적출자궁 6예에 자궁수축제 oxytocin, PGF, ergonovine maleate를 투여하여 다음 결과를 얻었다. 비임신자궁에서 oxytocin과 PGF는 ergonovine maleate보다 가가 23배, 26배의 효능을 가졌고, oxytocin은 PGF와 ergonovine maleate보다 약 126배, 145배의 효력을 가졌다. 임신전기자궁에서 oxytocin과 PGF는 ergonovine maleate보다 각각 1.6배, 1.8배의 효능을 가졌고, oxytocin은 PGF보다 약 9배, ergonovine maleate보다 약 5배의 효력을 가졌다. Oxytocin은 임신자궁보다 비임신자궁에 효력이 강하나, PGF와 ergonovine maleate는 비임신자궁보다 임신자궁에 효력이 강하게 나타났다. The response of the isolated uterus from pregnant (gestational period less than 10 days) and nonpregnant mouse to uterine stimulants, oxytocin, prostaglandin F₂α (PGF₂α )and ergonovine, was observed in low calcium Tyrode's solution. Potency was represented by the value of pD₂ which is defined as the negative logarithm of the concentration producting half- maximal response to each drug. In the non-pregnant uterus, the pD₂ values of oxytocin, PGF₂α, and ergonovine were 8.86, 6.76, and 6.70, respectively. In the pregnant uterus, the values were 8.45, 7.50, and 7.75, respectively. A maximal response produced by oxytocin was similar to that by PGF₂α in both pregnant and nonpregnant uterus. However, the maximal response to ergonovine in the nonpregnant uterus was one-twenty fifth the response to oxytocin and PGF₂α, and in the pregnant uterus it was a half the response to them.

Chronic eosinophilic pneumonia(CEP) is a rare disease of unknown etiology characterized by chronic infiltration of the lung with eosinophils. It presents with profound systemic symptoms comprising fever, night sweats, weight loss, dyspnea and blood eosinophilia with nonsegmental air-space consolidation confined to the outer third of the lung, the "photographic negative of pulmonary edema". Histopathologic features of chronic eosinophilic pneumonia are intraalveolar and interstitial infiltrations with eosinophils, histiocytes, giant cells, scattered lymphocytes and plasma cells. Glucocorticoid therapy cause prompt resolution of symptoms as well as disappearans of blood eosinophils, elevated serum Ig E levels and the roentgenographic lesions. Infrequent radiographic findings include nodular infiltrates, consolidations, cavitations, atelectasis and pleural effusions. Deaths from CEP although rare, have been reported, but the majorities of CEP have benign courses and do not need a therapy with ventilator. We report a case of chronic eosinophilic pneumonia, which had a sudden course associated with diffuse pneumonic consolidations on the both lung and bilateral pleural effusion.

李箱의 <烏瞰圖> 中 「詩第一號」의 한 硏究

金相培,柳在燁 단국대학교 1993 論文集 Vol.27 No.-

In this work, I approached Lee, Sang's "Sijeilho(The First Poem)" in a psychoanalytical view. of course, there might be various opinions from different views on the critique of the literary work as well as the writers' original views. The theme of "Ogamdo" and "Sijeilho" can be explained as the fear complex of self-crisis in his childhood. This fear complex was caused by the experience from three to six years old, the crucial period for establishment of self-concept(identity). That is, the fixation on apprehension of separation, caused by parting form his parents, and of psychosexual identity under conditions which he could not solve the Oedipus Complex. The poet's age was inferred from the word '13' of the poem. For Lee, Sang, the age '13' means the time when he was troubled with the fixation, which he could not expect further development of self-consciousness because of the unsolved self-development in his childhood. In the beginning of the youth, he met again his parents and it threw him in extreme unconscious fear again because of the manifestation of the latent inner conflicts with the age of puberty. Lee, Sang's retrogression as an experiment was interpreted for a solution of the fixation, the settlement of fear. To conclude, his abnormal life was expected by his choice of the structure of life. Also, the disease which led him to death when young might be the result of the unconscious wish for death in order to be free himself from fear.

Two-dimensional natural convection in a partially divided inclined square enclosure is investigated experimentally. Two opposite walls of the enclosure are adiabatic while the other two isothermal walls are maintained at different temperatures, and a partition is situated perpendicularly at the mid-height of one adiabatic wall. The flow visualization experiments are carried out with water, Pr=4.95, for two Rayleigh numbers, Ra=1.968x10?? and 3.936x10??. The inclination of enclosure is varied from -30°to 90°, and the length of a partition is varied from L=0 to L=11/13W. The length of a partition and the inclination of an enclosure are to significantly effect on the flow patterns within the enclosure. The transition to the primary circulating flow is occured at the inclination of 30°∼40°, and the strongest wall-boundary flow and the wide core-stagnation region are presented at the inclination of 50°∼60°regardless the partition length. An oscillatory motion of natural convection is also found to occur in certain lengths of a partition at θ=0°, such as an enclosure heated from below with a horizontal partition.

돈분 폐수의 효율적인 처리를 위해 6 W/㎡, 12 W/㎡와 24 W/㎡의 조도 하에서 온도를 15℃에서 40℃까지 각각 변화시켜, 광합성 미세 조류인 Spirulina platensis의 생육에 관한 최적 생육 조건 결정에 관한 실험을 하였다. 균체의 비생육속도는 30℃까지는 온도 증가에 따라 증가하였다. 균체의 생육에 있어서 온도의 영향을 설명하기 위해서 Arrhenius 식을 이용하여서 얻은 활성화 에너지 값은 13.5kal/mol이었다. 순수 배지에서 배양된 균체의 비생육속도가 0.31(1/day)인 반면 30% 돈분 첨가 배양시 얻은 균체의 비생육속도는 0.24(1/day)였다. 폐수내의 총 질소량과 이의 제거속도로 균체의 폐수 처리 능력을 평가할 수 있었다. 돈분 농도를 달리 첨가한 회분배양에 있어서 70~93%(PO_4^3- -P), 67~93%(inorganic nitrogen), 80~90% (COD) 그리고 37~56%(organic nitrogen)의 감소율을 보였다. 총-질소와 총-인의 1차반응 감소 속도 상수는 각각 0.17(1/day)와 0.14(1/day)로 계산되었다. 20% 돈분을 첨가하는 연속배양에 있어서 회석률이 0.20(1/day)일 때 최대 균체농도가 1.52(g/L)를 유지했다. 돈분처리 후 얻은 균체의 성분은 단백질이 58.7%, 지방 11.0% 그리고 회분이 15.6%였다. The kinetics of growing microalga, Spirulina platensis was investigated to treat swine wastes with optimum growth conditions. Temperature was varied from 15 to 40℃ at three different light intensities, 6 W/㎡, 12 W/㎡ and 24 W/㎡. The specific growth rate was increased as temperature increased up to 30℃. The activation energy was estimated as 13.5 kcal/mol by an Arrhenius relationship. 0.24(1/day) of specific growth rate was obtained from batch cultivation with 30% swine wastes, compared to 0.31 (1/day) from clean culture. It was found that Spirulina platensis was able to reduce 70~93% of PO_4^3- -P, 67~93% of inorganic nitrogen, 80~90% of COD and 37~56% organic nitrogen by adding various concentrations of swine wastes for 12 days of batch cultivation. Rate constants for removing nitrates and phosphates in treating swine wastes were estimated as 0.17 (1/day) and 0.14 (1/day) in the first order reaction, respectively. 1.52(g/L) of maximum cell density was maintained at 0.20(1/day) of dilution rate in continuous culture, adding 20% swine wastes for 30 days. The chemical composition of the biomass obtained from the process showed 58.7% of protein, 11.0% of lipid and 15.6% of ash.
