EPDM을 이용하여 제작된 바이오센서의 전기화학적 특성

유근배 청주대학교 2012 産業科學硏究 Vol.29 No.2

A biosensor bound by EPDM solved in toluene has been newly designed and a study of its electrochemical characteristics was carried out. Enzyme source was ground tissue of cabbage root. Volatilization of the solvent made the electrode material possess a mechanical robustness and a speedy signal appearance. And it showed electrochemically irreversible behaviors and a powerful catalytic power(detection limit = 5.0 x 10-5 M, S/N=2). The double reciprocal plot of signal current and substrate concentration was ideally linear and the symmetry factor and exchange current density of the electrode used in this work were 0.16 and 3.61 x 10-5 Acm-2 respectively.

류마티스성 심장판막질환, 우심방혈전 및 대동맥 협착증과 합병된 만성 혈전색전성 폐동맥고혈압 1예

유근배,심준,임양희,이진화,신길자 梨花女子大學校 醫科大學 醫科學硏究所 1998 EMJ (Ewha medical journal) Vol.21 No.4

폐동맥 혈전색전증은 비교적 드문 질환으로 주로 심부 정맥혈전에서 발생하는 것으로 알려져 있으며 류마티스성 심장판막질환을 가진 경우 합병되는 우심방 혈전이 드물게 폐혈전색전증의 원인이 될 수 있는데, 저자들은 대동맥의 동맥경화성 협착증을 동반한 류마티스성 심판막질환 환자에서 우심부전 및 우심방혈전에서 발생한 만성 혈전색전성 폐동맥고혈압1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Most pulmonary thromboemboli arise from the deep vein thrombosis, which have complete clinical and at least near complete roentgenographic and angiographic resolution within four to six week of the acute event. But chronic pulmonary hypertension and cor pulmonale from unresolved pulmonary embo-lism complicate acute embolic episode with a frequency of less than 1 percent. Rarely pulmo-nary thromboemboli can result from right atrial thrombi. We experienced a case of chronic thromoboembolic pulmonary hypertension, which wrose from right atrial thrombi in the patient with rheumatic valvaular heart disease and thoracic aorta atherosclerotics stenosis.

4,6-diaryl-1,2,3,5-oxathiodiazine-2-oxide와 amidine간의 반응에 관한 이론적인 연구

유근배 청주대학교 2009 産業科學硏究 Vol.26 No.2

DFT calculations were performed to investigate the cycloaddition reactions of 4,6-diaryl -1,2,3,5-oxathiodiazine-2-oxide with amidines. These relative reactivities were determined by FMO energy gap of Dod(LUMO)-amidine(HOMO) interaction and were then partially in accord with experimental trend(yield). Most reactions were occured with inverse electron demand type and thus Dod(LUMO)-amidine(HOMO) interaction preferentially played an important role in determining its reactivity, but the reaction between Dod and amidine(X=CCl3, Y=Cl) was neutal electron demand type, and thus both Dod(LUMO)-amidine(HOMO) interaction and Dod(HOMO)-amidine(LUMO) interaction had to be used to determine the relative reactivity in the cycloaddition reactions.

We can eat fresh Cucumber at the table all through the year by promotion of growth, and the cultivators more benefitial managerial production through harvesting an selling Cucumbers in short day. I make an experiment on the effect of P.V.C. and Poly in quantity and quality of Cucumbers in order to know the difference between Poly and P.V.C. which are used for this effective promotion of growth. I report it in this thesis. First... In the warm power of P.V.C. and Poly; the lower temperature of P.V.C. had more 0.5℃ to 1.5℃ than that of Poly, and the soil temperature of P.V.C. had more 1℃ to ℃ than that of Poly. Second... The effect of P.V.C. and Poly on the of Cucumber; In the vegetative-weight had 44.26g per a plant and dry-weight had 4.98g per a plant under the P.V.C. In the vegetative-weight had 39.06g per a plant and dry-weight had 4.90g per a plant there fore it is excellent more P.V.C. than Poly Third... The effect of P.V.C. an Poly mulching on the volume of Cucumber; The P.V.C. is very excellenter not only early volume but also total volume than the poly.

N-thioaroylformamidine과 ketene간의 고리화반응에 관한 이론적인 연구

유근배 청주대학교 산업과학연구소 2007 産業科學硏究 Vol.24 No.2

PM3 semiempirical MO calculations were performed to investigate the mechanism and relative reactivety for cycloaddition reactions of N-thioaroylformamidine(TFA) well kettle. Reactions of TFA with H-substeluted kettle were occurred with neutral electron demand, but those of TFA with Ph-substitutes kettle were - occurred with inverse electron demand. These relative reactivelies - were determined by FMO energy gap of TFA(LUMO)-ketene(HOMO)interaction and were then partially accord with experimental trens(yield). However theoretical activation barriers, which were determined from transition states, were in accord well experimental trend in all reactions. Electron witlsrawing group substituted on 4-memberes ring faciwelated the formation of all 4-membered-ring(TS) and thus decreased activation barriers in TS. But Ph-lublteluent interferes with the formation of 4-memberes ring sue to ell lteric hindrance.

무우 主要品種에 있어서 催芽種子의 低溫處理期間 및 播種時期의 差異가 地上部 및 地下部의 生長 및 花芽分化에 미치는 影響에 關하여 硏究하고저 1980年 4月∼11月까지 걸쳐 "晋州大坪무우" "40日무우" "서울봄무우" "赤丸20日무우" "太白무우" 및 "宮重總太무우"의 6品種을 供試하여 「實驗하고 또 寒冷絲로 2겹遮光, 1겹遮光, 無遮光하여 生育에 미치는 影響을 硏究하고 花芽分化의 程度 및 花芽分化와 生育과의 關係를 遮光의 程度와 聯關시켜 比較硏究함으로서 花芽分化에 미치는 程度의 影響을 複合的으로 比較分析코저 晋州大坪무우와 宮重무우의 2品種을 供試하여」 京畿道 安城農業專門大學 實習圃場에서 實驗을 行하였는데 그 主要結果를 物約하면 다음과 같다. 實驗Ⅰ 1. 日本무우 "40日무우"는 高溫期의 播種에는 잘 適應하여 地上部 및 根部의 發育이 他品種에 費하여 좋았으나 抽播時 播種時期가 지나치게 늦어지면 生育이 顯著히 지연되는 特性을 보였다. 2. 播種後의 經過日數를 基準으로 播種期 및 品種에 따른 生育을 比較할때 秋播適期에 屬하는 8月23日의 播種에서 가장 地下部의 肥大가 빠르게 進行되었으며 또한 地上部 根部의 比率이 가장 높았다. 3. 品種에 따른 花芽分化까지의 所要日數를 比較하면 東洋무우에서는 "晋州大坪무우"가 가장 빨랐으며 다음이 "40日무우" "太白무우" "宮重總太무우"의 順이었다. 特히 "晋州大坪무우"에서는 根部의 肥大가 전혀 이루어 지지 않는 경우는 많았다. 4. 西洋系무우인 "赤丸20日무우"는 早期春播時 花芽分化 및 抽苔가 一部 進行되였으나 東洋系무우에서는 달리 根部의 肥大가 大部分 正常的으로 進行되었다. 實驗Ⅱ 5. 催芽種子의 低溫處理期間의 長短은 低溫에 敏感하게 反應하는 "晋州大坪무우" "40日무우"等의 品種에서는 花芽分化까지의 所要日數를 뚜렷이 短縮시키지 못하였다. 6. 自然低溫에 感應하여 花芽分化하는 品種特有의 習性은 大體的으로 種子低溫處理에 感應하는 習性과 類似하였다. 7. 低溫處理效果가 比較的 적게 나타나는 "赤丸20日무우" "서울봄무우"에 있어서는 10日間의 種子低溫處理가 5日間의 低溫處理보다 花芽分化에 이르는 槪體數를 顯著히 增加시켰다. 8. 種子低溫處理期間의 長短은 東洋무우와 西洋무우의 花芽分化 習性의 差異點을 確實하게 보여주었다. 卽 東洋系인 "서울봄무우"의 花芽分化까지의 所要日數는 西洋系인 "赤丸20日무우"에 比하여 低溫處理期間이 길어질수록 短縮되었다. 實驗Ⅲ 9. 무우裁培時, 寒冷絲 被覆은 自然光線을 各各 20% 및 35%減少시켰으며 植物體의 生體重 및 乾物重은 遮光에 의해 顯著히 減少되었다. 10. 植物體의 乾物重/生體重 比率은 遮光處理에 依해 顯著히 減少되었으며 조선무우인 晋州大坪에서 더욱 그 減少 程度가 높았다. 11. 遮光에 依한 生育減少에도 不拘하고 花芽分化 및 抽苔는 거의 影響을 받지 않았다. Studies were conducted to investigate the effect of seed vernalization period and sowing dates on the growth of top and root of radishes (Raphanus sativus L.) Seeds of the leading radish cultivars, 'Jinzudaepyung', '40-day', '20-day', 'taebaek', 'Goongzung Chongtae', and 'Seoul Bommu', were either sown directly in the field at 6 defferent dates in 1980 or Seeds vernalized for 3 different period were sown on the same day in 1980. The experimental results, conducted and obtained at Ansung, Kyunggi-province, can be summarized as follows. 1. The Japanese radish cultivar, '40-day' exhibited some resistance to high temperatures by showing better top and root growth during the summer. However, when sown late in the fall, the growth was apparently in ibited as compared to that of other cultivars. 2. Comparing the growth of 60 days after seeding, better foot growth as well as the low top/root ratio was obtained from the plantings which supposed to be the optimum sowing date. 3. The time required from planting to visible flower bud development varied considerably depending upon the cultivar. 'Jinzudaepyung' showed the earliest flower bud development followed by '40-day', 'Taebaek', and 'Goongzung Chontae: When flower buds were formed early in the developmental stages, 'Jinzudaepyung' showed little or no root developement. 4. Unlike the oriental radish cultivars, the European cv. '20-day' showed considerable root growth even if the flower buds were formed and bolting proceeded. 5. The duration of seed vernalization, 5 and 10 days respectively, ahd little or no effect on the days required for the first inflorescence development in 'Jinzedaepyung' and '40-day' which were sensitive to low temperature. 6. The varietal characteristics of flower bud formation were similar between the plants received natural low temperature exposure and those received seed vernalization. 7. The longer the vernalization period, the higher the flower bud formation in 'Seoul Bommu' and '20-day' which were less sensitive to low temperatures. 8. The duration of vernalization clearly showed the differential response of flower bud formation between European and oriental radish cultivars. More plants of 'Seoul Bommu' showed flower buds as the duration of vernalization increased, as compared to '20-day'. 9. Shading with plastic net cut off the natural sunlight intensity 20% (1 layer) and 35%(2 layers), respectively, shading reduced both fresh and dry weight of 2 cultivars. 10. The radio dry weight to fresh weight was reduced significantly by shading especially in 'Jinzudaepyung' cutivar. 11. The percentage of flower bud differentiated an bolted plant was not influenced by shading treatment.
