粗飼料와 濃厚飼料를 混合한 飼料의 營養價를 Cellulase와 Amyloglucosidase, 酵母를 利用한 가스 生成法에 의하여 消化率과 TDN을 測定할 수 있는 方法을 確立하고자 本 硏究를 實施한 實驗 結果는 다음과 같다. 1. Cellulose 加水分解 酵素인 Trichoderma viride cellulase의 最適 活性 pH는 4.5-4.8이었으며 pH가 5.0보다 높을 때에는 活性이 急激히 저하하였다. 2. Cellulose 加水分解시 Trichoderma viride celulase의 溫度의 의한 影響은 50℃에서 最大 活性을 나타내었으며, 40℃에서는 活性이 92%정도로 나타났다. 3. Trichoderma viride-aspergillus niger 混合, cellulase 使用時의 가스 生成量은 Trichoderma viride cellulase 使用時 가스 生成量 보다 20-30% 높게 나타났으므로 cellulose 加水分解時 Trichoderma viride-aspergillus niger 混合 cellulase를 使用하는 것이 더욱 效果的일 것으로 思料된다. 4. 포도당(X)과 가스 生成量(Y)과의 關係는 Y=6.82+165X의 回歸式과 相關係數는 0.92로서 高度의 有意性(P<0.01)이 있었다. 5. Trichoderma viride cellulase 使用時 가스 生成量(X)과 乾物 消化率(Y)과의 關係는 Y=29.9+1.13X(r=78**)의 回歸式을 나타내었고, Trichoderma viride-aspergillus niger 混合 vellulase 使用時 가스 生成量(X)과 乾物 消化率(Y)과의 關係는 Y=28.9+0.88X(r=0.82**)의 回歸式을 나타내었다. Trichoderma viride cellulase 使用時 보다 Trichoderma viride-aspergillus niger 혼합 cellulase 사용시 相關係數가 더 높았다. 6. 가스 生成量(X)과 TDN(Y)과의 關係는 Y=35.8+0.585X의 回歸式과 相關係數 0.93으로서 高度의 有意性을 나타내었고, TDN(X)과 가스 生成量(Y)과의 關係는 Y=1.68X-59.6의 回歸式을 나타내었다. The experiment was conducted to establish the gas production method by cellulase, amyloglucosidase and yeast to determine the digestibility and energy value(TDN) of feedstuffs. The results obtained were summarized as follows; 1. The highest activity of Trichoderma viride cellulase was shown at pH 4.8 and the activity of the cellulase decreased rapidly at higher pH than 5.0. 2. The highest activity of Trichoderma virie cellulase was shown at 50℃ and the activity at 40℃ was approximately 92% compared with that at 50℃. 3. The mixed celllulases of Trichoderma viride and Aspergillus nigher produced more gas than Trichoderma viride cellulase when incubated with feedstuffs and were identified to be more effectively used for gas production method. 4. The regression equation of gas production(Y) on glucose production (X) was Y=6.82+165X with significant correlation coefficient of 0.92. 5. The regression equation of DMD(Y) on gas production(X) was Y=29.9+1.13X(r=0.78) with Trichoderma viride cellulase and Y=28.9+0.88X (r=0.82) with both Trichoderma viride and Aspergillus niger cellulase. 6. The regression equation of TDN(Y) on gas production(X) was Y=35.8+0.58X with significant correlation coefficients of 0.93 and in conclusion energy value of feedstuffs can be estimated by gas production method.

고지윤,손아현,신현수 대한한방내과학회 2018 大韓韓方內科學會誌 Vol.39 No.6

Objectives: The aim of this review is to investigate clinical studies on Oriental medicine treatment for aphasia after cerebrovascular disease. Methods: Using the keywords ‘Aphasia', ‘Oriental medicine', ‘Stroke' ‘Cerebral infarction', ‘Cerebral hemorrhage', and ‘Clinic', we searched domestic databases, including “NDSL (National Discovery for Science Leaders)", “Korean Traditional Knowledge Portal", “OASIS (Oriental Medicine Advanced Searching Integrated System)", and “RISS (Research Information Sharing Service)". Each keyword was not searched individually, but combined in various ways. To investigate recent trends, we limited our search to papers published after 2000. Papers that did not include a specific treatment method or did not match the subject “Aphasia after stroke" were excluded. Results: Using the searching method, 13 studies were found. Of these, 12 studies were in the form of case reports, while one was in the form of a non-randomized controlled trial. These studies showed positive results for the use of Oriental medicine in terms of the Korean version of the Western Aphasia Battery (K-WAB), the evaluation form on functional performance capability and accuracy of articulatory organs developed by Lee, aphasia screening test refered in ‘Assessment in Speech-Language Pathology' and adapted properly to Korean, the Communicative Ability in Daily Living Test (CADLT), the Korean Version-Boston Naming Test (K-BNT), and language assessment items included in CNS, and NIHSS. Conclusions: Of the 12 case reports, 11 studies showed positive results of the use of Oriental medicine for treatment of aphasia after cerebrovascular disease. However, more sophisticated and large-scale clinical research on aphasia should be conducted.

Aerosol optical properties derived from the DRAGON-NE Asia campaign, and implications for a single-channel algorithm to retrieve aerosol optical depth in spring from Meteorological Imager (MI) on-board the Communication, Ocean, and Meteorological Satelli

Kim, M.,Kim, J.,Jeong, U.,Kim, W.,Hong, H.,Holben, B.,Eck, T. F.,Lim, J. H.,Song, C. K.,Lee, S.,Chung, C.-Y. Copernicus GmbH 2016 Atmospheric Chemistry and Physics Vol.16 No.3

<P>Abstract. An aerosol model optimized for northeast Asia is updated with the inversion data from the Distributed Regional Aerosol Gridded Observation Networks (DRAGON)-northeast (NE) Asia campaign which was conducted during spring from March to May 2012. This updated aerosol model was then applied to a single visible channel algorithm to retrieve aerosol optical depth (AOD) from a Meteorological Imager (MI) on-board the geostationary meteorological satellite, Communication, Ocean, and Meteorological Satellite (COMS). This model plays an important role in retrieving accurate AOD from a single visible channel measurement. For the single-channel retrieval, sensitivity tests showed that perturbations by 4 % (0.926 ± 0.04) in the assumed single scattering albedo (SSA) can result in the retrieval error in AOD by over 20 %. Since the measured reflectance at the top of the atmosphere depends on both AOD and SSA, the overestimation of assumed SSA in the aerosol model leads to an underestimation of AOD. Based on the AErosol RObotic NETwork (AERONET) inversion data sets obtained over East Asia before 2011, seasonally analyzed aerosol optical properties (AOPs) were categorized by SSAs at 675 nm of 0.92 ± 0.035 for spring (March, April, and May). After the DRAGON-NE Asia campaign in 2012, the SSA during spring showed a slight increase to 0.93 ± 0.035. In terms of the volume size distribution, the mode radius of coarse particles was increased from 2.08 ± 0.40 to 2.14 ± 0.40. While the original aerosol model consists of volume size distribution and refractive indices obtained before 2011, the new model is constructed by using a total data set after the DRAGON-NE Asia campaign. The large volume of data in high spatial resolution from this intensive campaign can be used to improve the representative aerosol model for East Asia. Accordingly, the new AOD data sets retrieved from a single-channel algorithm, which uses a precalculated look-up table (LUT) with the new aerosol model, show an improved correlation with the measured AOD during the DRAGON-NE Asia campaign. The correlation between the new AOD and AERONET value shows a regression slope of 1.00, while the comparison of the original AOD data retrieved using the original aerosol model shows a slope of 1.08. The change of y-offset is not significant, and the correlation coefficients for the comparisons of the original and new AOD are 0.87 and 0.85, respectively. The tendency of the original aerosol model to overestimate the retrieved AOD is significantly improved by using the SSA values in addition to size distribution and refractive index obtained using the new model. </P>
