A ten months old, female Yorkshire terrier weighing 2.88 kg referred to veterinary teaching hospital of college of veterinary medicine, Konkuk University because of syncope, cough and dyspnea. First hematological and serum chemical test revealed thrombocytopenia, mild anemia, and increase of concentration of ALP (195 U/L). On 57 days later, second hematological and serum chemical test revealed polycythemia, increase of concentration of ALP (211 U/L), and Tchol (387 mg/dl). Right atrium enlargement, main pulmonary artery bulge and cardiomegaly (VHS = 11.5) were observed in radiographic findings. Ultrasonographic images showed both right and left ventricular dilation and turbulent flow between the descending aorta and the main pulmonary artery in color Doppler imaging. ECG showed left ventricular enlargement, SA block, and electrical alternant. Thoracotomy was performed through left fourth intercostal incision under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. Cough and dyspnea disappeared on 5 days after operation. Turbulent flow was not found in color doppler imaging of ultrasonography on 10 days after operation. Ten months later after the operation, syncope could not exist any more.

The wind resistant design of building generally used up to data has been based on the value of an extreme speed. The extreme speed is normally estimated from wind data observed for the return periods of last 50 years or 100 years on the basis of the importance of building to be constructed. However, it is essential to consider the time variance of wind action because strong winds originated by Typhoon or others are occationally coming for attack. This study is to examine the origin of occurence and the action time of strong wind, and to understand the time variance characteristics. Strong winds are divided into 3 parts such as the regional condition of Korea, namely Typhoon, Frontal system storm, and Monsoon. The areas reflecting the origin of 3 kinds of the strong winds are also devided are selected as such as Seoul-Kyongki, Jungbu, and South-seashore. The representative cities are selected as Seoul fro, Uljin and Kunsan for, and Busan and Yeosu for. Observed wind data of past 20 years will be employed to estimate duration and propability of wind velocity. The observed wind data are recorded with duration of 96 hours at the center that annual extreme wind speed takes place, and with the mean value of wind velocity during 10 minutes at 1 hour interval. Based on these investigations, the duration and probability of wind velocity should be estimated. Generalized probability distribution function of wind velocity will be proposed. Duration of strong winds presented as a function of its maximum wind velocity. From these results, multipling generalized distribution function by generalized number of (wind velocity) samples, approximate equation of wind-duration will be derived. Approximate equation of wind-duration proposed in this study should be useful for analysing fatigue damage of structures and time dependent analysis of structure under strong wind in Korea.

Chrysanthemums (Asteraceae) are important ornamental crops in worldwide that are well known as commercial valuable cultivars for cut flowers, potted plants, and garden flowering plants. Genus chrysanthemum consisted of 41 species that are mostly distributed in East Asia. Chrysanthemum has diverse ploidy levels with the basic chromosome number of x=9 from 2n=2x=18 (diploid) to 2n=10x=90 (decaploid). Fluorescence in situ hybridization (FISH) is a useful tool for studying the distribution of ribosomal DNAs. In this study, we have confirmed ploidy level by chromosome counting method. The somatic metaphase chromosome numbers were observed 2n=2x=18 in Chrysanthemum boreale, and 2n=6x=54 in C. indicum and C. zawadskii. More detailed Karyotype was constructed based on FISH method using 5S and 45S rDNA probes. Two (2) loci of 5S rDNA signals were detected in interstitial region of long arm chromosome in C. boreale and six (6) loci were in C. indicum and C. zawadskii. All of 45S rDNAs were located in terminal region of short arm chromosome which were visualize in six (6) loci in C. boreale and C. indicum and twelve(12) loci in C. zawadskii. In this study, it was the main topic to perform physical mapping of the location of 5S and 45S rDNA. Three of wild chrysanthemum showed variations in number of ribosomal DNAs. In the present investigation will help to further study of genome sequencing project in chrysanthemum.

Purpose: Atopic dermatitis is often accompanied by food allergies which occur through skin barrier defects. Especially Staphylococcus aureus colonization can exacerbate skin barrier defects that cause sensitization and increase specific IgE (sIgE) to food. We investigated the association between skin colonization and food sIgE changes in children with atopic dermatitis. Methods: Atopic dermatitis was diagnosed by a pediatric allergist in patients between 3 months and 3 years of age. Total IgE and sIgE to egg white, cow`s milk, wheat, and peanuts were taken. Eosinophil count and eosinophil cationic protein were also taken. Comparisons were done between the groups with and without S. aureus colonization. Results: It was found that 50.3% of the 294 enrolled patients had S. aureus colonization on lesional skin. Statistically significant sensitization to wheat and peanut were increased with S. aureus colonization. Statistically significant increases in sIgE (above cutoff level) were also found in egg white, milk, wheat and peanut. Higher S. aureus colony counts also increased sIgE of all foods. Methicillin-resistant S. aureus showed no statistical difference compared to methicillin-susceptible S. aureus in severity and sIgE levels. Conclusion: S. aureus colonization increases the risk of food sensitization in children with atopic dermatitis. (Allergy Asthma Respir Dis 2017;5:193-199)
