無對象繪畵의 根據와 限界

表丞鉉 誠信女子大學校 1976 硏究論文集 Vol.9 No.-

Among the pros and cons for non-objective art, the analogy of the pure music is very important. But what is possible to the music is not always possible to the painting. There is a serious difference between spacial art and music-time-expression. One of the critics suggests that the thinness of non-objective painting is due to the relative shallowness of the space within which the painting is composed of. This may not be true. The shallowness is not of the space but of time. As the time is the essence of life, a tendency of retreat of humanty results in that sort of art. We can not underetand it without the knawlege of the back-round; the artist himself, his opinion, ism etc., separhtely from of art.

The object of this study was to identify source categories of Busan area through FA/MA methodology which contribute to the concentration of suspended particles at receptor. According to the purpose of this study, twenty-seven chemical species such as elements, anions, and total carbon of chirty-six PM10 and TSP data sets sampled at Bumchun receptor site for a 24hr period from May to Aug. 1992, were analyzed and applied to FA/MA model. From this study, the following conclusions were obtained. From the factor analysis for measured data, steel, mill-related, transportation, soil dust resuspension, marine, fuel oil, secondary aerosol source, and etc., of which total variance explained by the identified factors was calculated as 84 ∼ 91%, were identified. And the trend was shown that the more the number of input trace materials was, the more difficult the identifications of factors were, relatively. Selecting the representive tracers for identified factors based on the factor loadings, the following equations were obtained by use of stepwise method in multiple linear regression for the cases. TSP(㎍/㎥) = 27.996+0.033Mg +0.016Cl-+0.O05SO42 Case 1 TSP(㎍/㎥) = 11.779 + 2.013Ti + 0.034Na + 0.026Mg + 0.006ca Case 2 PM10(㎍/㎥) = 3.130+0.O04 SO42 +0.010 Cl- + 1.812Ti Case 1 PM10(㎍/㎥) = -14.028+1.515Ti +0.D38Na + 0.O09 Cl- + 0.003 SO42- Case 2 In comparison with the results of FA/MR model with the change of the newly added input tracers, the case with TSP showed relatively unstable results of factor analysis for the case studies because of insufficient number of data available to complete a factor analysis for the tracers used.

This experiment was performed to clarify the role of brainstem for rhythm generation of mastication induced by stimulation of cerebral cortex. Rabbits were anesthetized with urethane and a pair of wire electrode was inserted into anterior digastric and masseter muscles, respectively. Experimental animal was placed to stereotaxic apparatus and occipital craniotomy and cervical laminectomy was performed to expose caudal brainstem. Cortically-induced mastication was evoked by electrical stimulation of cerebral masticatory area with concentric bipolar electrode and neural activity of brainstem and EMGs of masseter and anterior digastric muscle were recorded. The results obtained were as follows: 1. The neural activity of bulbar reticular formation was recorded at rostral 2-4㎜, lateral 0.5-1.5㎜ to obex and 1.5-2.5㎜ below the bulbar surfafce. 2. The site that neural activity corresponding with EMGs of masticatory muscles was recorded was medial bulbar reticular formation(MBRF) 3. The neural activity of medial bulbar reticular formation(MBRF) was corresponded with anterior digastric or masseteric EMG, respectively. 4. The neural activity of medial bulbar reticular formation(MBRF) and anterior digastric EMG was simultaneously recorded by twin pulse stimulation of contralateral cerebral masticatory area, and stimulation of ipsilateral medial bulbar reticular formation(MBRF) evoked anterior digastric EMG.

대기 건식침적 측정을 위한 물표면 매체 포집기의 성능평가

이승묵,정장표 이화여자대학교 환경문제연구소 1998 이화환경연구 Vol.2 No.-

원형 모양의 물 표면 매체 포집 기기가 대기중의 가스와 입자들의 건식 침적 유동량을 측정하기 위하여 개발되었다. 포집 기기는 날카로운 모서리와 아크릴로 만들어진 판(지름 37cm, 깊이 0.5cm)에 순환시스템을 통하여 계속해서 물이 공급되어지는 구조로 설계되어 있다. 물 표면 매체 포집 기기의 성능을 평가하기 위하여 황산염, 칼슘 그리고 납의 유동량(flux)을 일리노이주(Illinois) 시카고(Chicago)에서 측정하였다. 대기중 입자상의 건식 침적 유동량을 측정하기 위하여 날카로운 모서리를 지닌 침적판 위에 놓여진 그리스 표면 매체를 물 표면 매체와 동시에 대기중에 노출하였다. 통계학적 분석 결과에 의하면 칼슘과 납의 유동량(flux)은 두표면 매체에서의 침적량이 동일한 것으로 분석 평가되어져 물과 그리스 표면 매체는 입자상의 침적에 대해서는 동일한 특성을 지니는 것으로 판명될 수 있었다. 황산염의 건식 침적의 경우, 가스상(SO₂) 과 입자상(SO₄())의 물질이 동시에 물로 침적될 수 있기 때문에 황산염을 시험대상 화합물로 선택하였다. (이산화황은 물 속에서 빠르게 가수 분해되고 황산염으로 산화된다). 이산화황(SO₂ )의 유동량을 물 표면 매체와 그리스 표면 매체사이의 황산염 유동량의 차이에 의하여 결정하였다. 저항모델(resistance model)을 사용하여 계산한 개별 이산화황 기체상 질량전달계수(individual SO₂gas phase mass transfer coefficient)와 대기중의 이산화황 농도를 곱하여 황산염 유동량을 예측하였다. 저항 모델은 질량 전달을 일련의 저항들을 통과하는 전기 및 열적 흐름과의 유사성과 연관지어서 개발한 모델이다. 물 표면 매체 포집기기를 사용하여 직접 측정한 이산화황 유동량을 저항 모델을 사용하여 예측된 유동량들과 잘 일치하였다. 이 결과는 물 표면 매체 포집기기가 대기중에서 가스상과 입자상의 물질로 동시에 존재하는 질소 화합물, PCBs, PAHs 및 수은과 같은 화합물질들의 침적을 측정하는데도 유용하게 쓰일 수 있는 가능성을 시사하고 있다. A circular water surface sampler was developed to measure the dry deposition flux of atmospheric gases and particle. The sampler consists of a sharp edged, acrylic plate, filled with water(37cm in diameter and 0.5cm deep) that is continuously replenished from a reservoir by a pump that maintains a constant water depth. To evaluate the water surface sampler, the flux of sulfate, calcium and lead were measured in Chicago. IL. A sharp edged greased surface was exposed to the atmosphere simultaneously with the water surface to measure the dry deposition flux of atmospheric particles. Calcium and lead fluxes were found to be statistically the same indicating that the water and greased surfaces had the same particulate phase deposition characteristics. Sulfate was also selected as the test compound because it can be deposited to water as both a gas(SO₂) and particulate(SO₄()) from the atmosphere(SO₂is quickly hydrolized and oxidized to SO₄() in water). The flux of SO₂was determined from the difference in the sulfate flux between the water surface and the greased surface. For each sample the calculated SO₂ flux was calculated as the product of the individual SO₂ gas phase mass transfer coefficient calculated using a resistance model multiplied by the ambient SO₂ concentration. A resistance model was developed by analogy to electrical or heat flow through a series of resistances. The SO₂ fluxes measured directly with the water surface sampler agreed well with those predicted with the resistance model. These findings indicate this sampler will be useful for measuring the deposition of other compounds which exist in both the gas and particulate phases like nitrogen, PCBs, PAHs and Hg.

3,4-Dihydroxyphenyl-L-alanine의 효소적 생산에 대한 반응첨가물의 영향

재조합 대장균에서 과발현된 Citrobacter freundii KCTC 2006 유래의 tyrosine phenol-lyase(E.C.4.1.99.2) 이용 3,4-dihydroxyphenyl-L-alanine (L-DOPA)의 생산에 대한 반응첨가물의 영향을 조사하였다. 반응액 중 효소 및 조효소 농도의 영향을 조사한 결과, 효소농도는 약 2 units/ml이 적합하였으며, 조효소인 pyridoxal -5-phosphate 는 0.1 mM 이상이 필요하였다. Pyrocatechol과 결합하여 안정한 복합체를 형성하는 sodium borate는 pyrocatechol에 의한 효소의 불활성화를 감소시키는 효과가 있었으나, 효소의 반응성을 현저히 저하시켜 L-DOPA 생산의 관점에서는 불리한 단점도 있었다. 한편, 알콜류 등의 유기용매가 L-DOPA 합성반응에 미치는 영향을 조사한 결과 methanol을 5% 농도로 반응액에 첨가하였을 때, 효소의 반응과 안정성이 크게 증가하여 L-DOPA 합성반응이 지속적으로 수행됨으로써 고농도의 L-DOPA를 효율적으로 생산할 수 있게 되었다. 생산된 L-DOPA의 약 77%가 불용성 상태로 침전되어 쉽게 회수할 수 있었으며, 침전된 L-DOPA를 1N HCI에 용해한 후 재결정화 함으로써 최종적으로 99.96%의 고순도 L-DOPA를 생산할 수 있었다. The enzymatic synthesis of 3,4-dihydroxyphenyl-L-alanine (L-DOPA) was examined for the effects of the reaction additives such as sodium borate, alcohol, and organic solvents. The enzyme used was tyrosine phenol-lyase of Citrobacter freundii KCTC 2006 produced in Escherichia coli. The amounts of tyrosine phenol-lyase and pyridoxal -5-phosphate were optimized to 2.0 units/ml and 0.1 mM, respectively, for the synthetic reaction. Sodium borate, a substance that forms a complex with pyrocatechol, reduced the enzyme deactivation by pyrocatechol although it seriously inhibited the enzyme activity. Among the organic solvents tested, dimethylsulfoxide, dimethylformamide, and alcohol increased the productivity of the L-DOPA synthesis. In a reaction system with 5% methanol, L-DOPA concentration increased up to 210 mM after 24 hours, and 77.1% of which was separated as precipitates. The L-DOPA was purified to 99.96%

깨달음의 교육의 탈현대적 의미

홍승표 계명대학교 사회과학연구소 2000 한국사회과학연구 Vol.19 No.2

The purpose of this article is to reveal the post-modern implications of the Buddha's education. The modern education falls in a crisis in the sense that it is for the industrial society. Its main purpose is to cultivate a worker. As the automation of production proceeds, the social needs for workers are being dramatically reduced. Modern education can not meet the needs of the future society. Therefore, we should look for a new type of education based on the new world views. The buddha's education can be one of the new types. It is based on a view of the world as unity(統一體的 世界觀). A view of the world as unity assumes that everything in the world is united. In other words, an individual involves the whole. Therefore, by the realization of oneself(an individual), we can realize the whole cosmos(the whole). Buddha tried to lead his disciples to awake the oneness of the world. He taught to throw away the small self. When we do it, the great and cosmic self emerges. We can live hamonic life with our friends and nature. It is the change of the dimension of our life. By following the Buddha's teaching, we can be very beautiful being. By changing our existential level, we can change the world. The buddha's education based on a view of the world as unity is very old but it has new meanings in building post-modern civilization. The modern education becomes outmoded. It does not fit to imfomation society. In future society, we do not need so many workers. The fundamental goal of the education should be changed. To who produces only a little and wastes only a little, and to build a man who pursue the awakening the Tao and does not pusue the more possessions and consumtions should be the fundamental goals of the education in future society. The buddha's education can provide us with fluent ideas for that purpose.
