Claudin-1, -2, -4, and -5: comparison of expression levels and distribution in equine tissues
Bonn Lee,Hee Young Kang,Dong Oh Lee,안창환,Eui-Bae Jeung 대한수의학회 2016 Journal of Veterinary Science Vol.17 No.4
Claudins, which are known as transmembrane proteins play an essential role in tight junctions (TJs) to form physical barriers and regulateparacellular transportation. To understand equine diseases, it is helpful to measure the tissue-specific expression of TJs in horses. Major equinediseases such as colic and West Nile cause damage to TJs. In this study, the expression level and distribution of claudin-1, -2, -4, and -5 ineight tissues were assessed by Western blotting and immunohistochemistry methods. Claudin-1 was primarily identified in the lung,duodenum, and uterus, claudin-2 was evenly observed in equine tissues, claudin-4 was abundantly detected in the liver, kidney and uterus,and claudin-5 was strongly expressed in the lung, duodenum, ovary, and uterus, as determined by Western blotting method. The localizationof equine claudins was observed by immunohistochemistry methods. These findings provide knowledge regarding the expression patternsand localization of equine claudins, as well as valuable information to understand tight junction-related diseases according to tissue specificityand function of claudins in horses.

Climate Change Signal Analysis for Northeast Asian Surface Temperature
Jeong-Hyeong, LEE,Byungsoo, KIM,Keon-Tae, SOHN,Won-Tae, KOWN,Seung-Ki, MIN,Meteorological, Institute of the University of Bonn) China Ocean Press ; Springer-Verlag 2005 Advances in atmospheric sciences Vol.22 No.2
<P>Climate change detection, attribution, and prediction were studied for the surface temperature in the Northeast Asian region using NCEP/NCAR reanalysis data and three coupled-model simulations from ECHAM4/OPYC3, HadCM3, and CCCma GCMs (Canadian Centre for Climate Modeling and Analysis general circulation model). The Bayesian fingerprint approach was used to perform the detection and attribution test for the anthropogenic climate change signal associated with changes in anthropogenic carbon dioxide (CO2) and sulfate aerosol (SO42-) concentrations for the Northeast Asian temperature. It was shown that there was a weak anthropogenic climate change signal in the Northeast Asian temperature change. The relative contribution of CO2 and SOl- effects to total temperature change in Northeast Asia was quantified from ECHAM4/OPYC3 and CCCma GCM simulations using analysis of variance. For the observed temperature change for the period of 1959-1998, the CO2 effect contributed 10%-21% of the total variance and the direct cooling effect of SO42- played a less important role (0% 7%) than the CO2effect. The prediction of surface temperature change was estimated from the second CO2+SO24- scenario run of ECHAM4/OPYC3 which has the least error in the simulation of the present-day temperature field near the Korean Peninsula. The result shows that the area-mean surface temperature near the Korean Peninsula will increase by about 1.1° by the 2040s relative to the 1990s.</P>

실험적으로 당뇨병을 유발시킨 개에 있어서 혈당량과 Hemoglobin A<sub>1</sub> 농도의 변화의 시간적인 상관관계
이창우,김본원,Lee, Chang-woo,Kim, Bonn-won 대한수의학회 1998 大韓獸醫學會誌 Vol.38 No.4
Fifteen mongrel dogs (14 male and 1 female) were injected intravenously with 30mg of streptozotocin and 50mg of alloxan monohydrate per kilogram of body weight to induce diabetes mellitus. Before treatment with streptozotocin and alloxan fasting serum glucose concentration was determined every other day or thrice a week (Monday, Wednesday, Friday) for 3 months. Among 15 dogs 4 dogs developed diabetes mellitus and survived more than 9 weeks without injection of insulin. After treatment fasting serum glucose and hemoglobin $A_1$ concentrations of the 4 dogs were determined every other day or thrice a week. Fasting serum glucose concentration increased acutely from 24 hours after treatment and then showed severe fluctuation. Hemoglobin $A_1$ concentration increased gradually until 7~9 weeks after treatment and then showed very slow increase afterwards. Correlation of hemoglobin $A_1$ to fasting glucose concentration was relatively weak(r = 0.10~0.80). Hemoglobin $A_1$ and fasting glucose concentration of preceding 7 week showed very high correlation (r = 0.98~0.99). It was indicated that hemoglobin $A_1$ concentration in chemically induced diabetic dogs reflects mean glucose concentration of preceding 7~9 weeks.

Robust Output Voltage Tracking Control for Uncertain AC/DC Converter
Hyo Chan Lee,Yeon Ji,Sangwoo Park,Bonn Koo,Seok-Kyoon Kim 제어로봇시스템학회 2021 제어로봇시스템학회 국제학술대회 논문집 Vol.2021 No.10
In this study, a cascade voltage control strategy is proposed for a three-phase AC/DC converter in the presence of parametric uncertainties. The contributions of this article are comprised of two parts. The first one is to devise the inner-loop controller through a simple feedback-linearizing method employing the optimal control gain maximizing the decay ratio of the current tracking error, using the lower and upper bounds of the true parameter value. Moreover, it is shown that the resulting closed-loop system including the first-order internal dynamics is stable. The second one is to investigate that the outer-loop proportional-integral (PI) controller renders the output voltage tracking error dynamics to be asymptotically stable despite the parameter uncertainties, provided that its control gains are chosen to be positive. Simulation results using powerSIM (PSIM) software show that the proposed control scheme provides satisfactory voltage-tracking performance for a wide output voltage operation range.

Although a majority of seniors continue to express interest in using mobile social network sites (MSNSs), research has yet to provide sufficient understanding of this very large market's motivations related to MSNS usage. As a viable consumer business segment, seniors are attractive enough to warrant potential MSNSs to invest necessary capital for developing tourism related MSNS designed to assist with this market's decision making and ultimately with their purchasing behavior. To address this gap, a research model was developed for this study using seniors having used MSNSs for purposes directly related to tourism and travel. Findings revealed intrinsic motivations had stronger effects on flow experience than did extrinsic motivations. Flow experience was found to have the greatest effect on subjective well-being, which in turn highly influenced purchase intention. Results documented that senior MSNS users differed significantly according to levels of anxiety attachment. Findings provide theoretical and practical contributions for tourism research, products, and services regarding senior MSNS consumers.

소의 호흡기 감염증에 대한 Danofloxacin과 Oxytetracycline의 효과 비교
이창우,김본원,김철규,조영웅,Lee Ghang-Woo,Kim Bonn-Won,Kim Cheol-Kyu,Jo Yong-Woong 한국임상수의학회 1993 한국임상수의학회지 Vol.10 No.1
A total of 108 Holstein calves with an average body weight of l19kg was studied in 4 farms in middle region of South Korea in late Autumn from November 8 to 27, 1991. Individuals were selected for treatment when they exhibited acute signs of pneumonia and had a rectal temperature of$\geq$4$0^{\circ}C$. Each animal received intramuscularly either danofloxacin at 1.25mg/kg once daily or oxytetracycline at 10mg/kg once daily for three consecutive days. The individuals which had a rectal temperature of$\geq$39.5$^{\circ}C$ at 24 hours after the third treatment received two further treatments. Treatment for three or five days with danofloxacin was very efficacious and superior to oxytetracycline in the treatment of calve pneumonia. Eighty-six per cent of 58 danofloxacin treated calves and sixty-six per cent of 50 oxytetracycline teated calves responded successfully to treatment for three days and the difference between treatment groups was highly significant. Danofloxacin was more efficacious than oxytetracycline in rapid and complete control of pyrexia and in resolution of clinical signs. The minimum inhibitory concentration of danofloxacin for Pasteurella hemolytica and Pasteurella multocida was equally 0.12~0.50 mcg/$m\ell$ while that of oxytetracycline for Pasteurella hemolytica and Pasteurella multocida was 2.0~4.0 and 4.0~16mcg/$m\ell$, respectively. During the treatment period side effect was not found in all animals of both treatment groups except some animals receiving oxytetracycline showed pain at the site of injection.

This study examined metabolic profiles of 1349 Holstein cows from 91 commercial herds. Thirteen parameters which are consisted of twelve blood components and body condition score were examined and their mean values. standard deviations and standard limits, which are 80% confidential limits, in each lactational stage were reported. The variations of each parameter affected by season, individual milk yield, adjusted corrected milk yield of herd. and lactation number were also reported. A model of metabolic profile test applicable to this country where the average number of cows in a herd is small as to be fifteen is designed. Metabolic profiles as reflected in each parameter were discussed in relation to adequacy of dietary intake for production, milk production, reproductive performance, and diseases, and the possible measure to improve productivity of dairy cows were proposed. Much of the variation in parameters was due to differences between herds, and less to differences between seasons, differences between individual milk yield, and differences between lactational stages. As the average herd size in this country is small, it is believed that all the cows in a herd must be sampled, and the individual result of each parameter was compared with the standard limit for each lactational stage, and the percentage of cows which are outside the standard limits in a herd was calculated to use as a criteria for evaluation of the herd. Data outside the 99% confidential limits were to be deleted at first, but when the trends of the data outside the 99% confidential limits are same as the trends of the data within 99% confidential limits, the deleted data must be reviewed again, otherwise some important informations would be missed. The mean concentration of blood urea nitrogen in this study was much higher than that was reported in England, U.S.A. and Japan, and it was similar to the upper limits reported in England, U.S.A. and Japan. So it was thought that the concentration of blood urea nitrogen is improper as a criteria for protein intake. The increase of serum total protein cocentration beyond standard limits was due to increase of serum globulin concentration in most of the cows. The correlation coefficient between serum and protein and serum globulin concentration was 0.83. Serum globulin concentration was negatively related to adjusted corrected milk of herd. Serum albumin, calcium and magnessium concentrations were negatively related to adjusted corrected milk of herd, which indicate that high-producing individual or high-producing herd have not taken sufficient protein/amino acids, calcium and magnessium. Packed cell volume was negatively related to adjusted corrected milk of the herd, and the trend was same In each lactational stage. The correlation coefficient between serum and packed cell volume was 0.16 and the correlation was very weak. Blood glucose concentration was lowest in early lactational stage, which indicates negative energy balance in early lactational stage. Blood glucose concentration was negatively related to adjusted corrected milk of herd from peak to late lactational stage, which indicates negative energy balance during the period in high-producing individuals or high-producing herds. Correlation coefficient between serum aspartate aminotransferase activity and serum ${\gamma}$-glutamyltransferase activity was 0.41, and this indicates that serum ${\gamma}$-glutamyltransferase should be included as a parameter of metabolic profile test to evaluate liver function. Body condition score of dairy cows in this country was lower than that of Japan in every lactational stages, and the magnitude of increase in body condition score during middle and late lactational stages was small. Metabolic profile can not be evaluated with solely nutritional intake. When an individual or large percentage of cows in a herd have adnormal values In parameters of metabolic profile tes
