A 11-year-old Yorkshire terrier anesthetized for computed tomography. The dog showed cyanosis and syncope during postanesthetic recovery, therefore drug administrated parenterally. Goose-honking was noticed after full recovery. As a result of survey radiography and fluoroscopy, grade 4 tracheal collapse was diagnosed. Prescription for the dog was oral administration of hydrocodone 0.22 mg/kg. theophylline 20 mg/kg, prednisone 0.5 mg/kg, amoxicillin 22 mg/kg and chlorpheniramine 2 mg/kg twice a day for 3 days. A 10-year-old Pomeranian was diagnosed as grade 2 traceal collapse at the local animal hospital 2 years before being referred to the veterinary teaching hospital of Chungnam National University. On physical examination, goose-honking, coughing and intermittent open-mouth breathing. Tracheal narrowing was observed on survey einradiography and fluoroscopy. Oral administration of theophylline 13 mg/kg, enrofloxacin 5 mg/kg, chlropheniramine 0.5 mg/kg twice a day was prescribed for 2 weeks.

Aluminizing-treated structural steel is excellent in high temperature oxidation resistance, wear resistance and corrosion resistance. So, it has been widely used for the machine parts which have required such properties. However it is difficult to find out any study result of the notched influence on the aluminizing-treated materials and the second diffusion materials. In this investigation the low carbon steel plates with with V-notches were coated with aluminum and made into second diffusion. With these specimcns the bending fatigue strength and fatigue life were observed and also crack propagation of alloy layer was investigated. The results obtained are as follows: 1) On the smoothed specimens a fatigue limit of aluminizing material was lower than the one of raw material, but it was more increased than the one of heat treatment material, and the fatigue limit of second diffusion material was lowest. 2) On the V-notched specimens a fatigue limit of aluminizing material was higher with 44% increase ratio than the one of raw material and with 63% increase ratio than the one of heat treatment material, and the rate of increase became lower increase ratio in a fatigue limit comparing to aluminzing material, with no influence of notch radius. 3) According as the notch radius became smaller, the fatigue limit became. higher on the raw material, it was same on th aluminizing material and lowest on the second diffusion material. 4) Crack initiation period was 0.04% below of fatigue crack life and the full growth period of crack propagation at alloy layer was 0.1%. The crack propagation from alloy layer to matrix was 16% of the fatigue crack life. This means that the crack propagation rate at alloy layer was very fast but the crack delay at the boundary of both was so long. 5) Crack propagation grows through defects, inclusion, peeling and previous boundary.

Quantitative determination of diarylheptanoids (oregonin and hirsutanonol), which were characteristic components of Alnus spp. has been conducted by High Performance Liquid Chromatography. The HPLC analysis was carried out using an YMC J'sphere ODS-H80 column [150×4.6mm, S-4μm. 80A(particle)] and a combination of acetonitrile and H2O was used as mobile phase in gradient solvent system. The results showed differnce in the species (Alnus japonica, A hirsuta and A. hirsuta var. sibirica)

This study is to analyze location conditions for erosion control dams to be constructed in Chungcheongnam-do, Daejeon Metropolitan City, Chungcheongbuk-do and Gyeongsangbuk-do in order to establish proper conditions for erosion control dams in the future. 199 sites where erosion control dams are expected to be built in 2010 were chosen and investigated in terms of 12 factors including basin area, basin slope, and landslide risk. The results showed that erosion control dams for Chungcheongnam-do and Daejeon Metropolitan City are mostly impermeable gravity dams mainly composed of concrete. In contrast, Chungcheongbuk-do and Gyeongsangbuk-do are increasing the number of permeable or compound erosion control dams. Basin analysis at planned erosion control dam sites showed that at least 44.5% of the total area has high landslide risk. Gyeongsangbuk-do had the largest basin area for erosion control dam sites at 157.3ha, followed by Chungcheongbuk-do at 64.4ha and Chungcheongnam-do at 54.8ha. Analysis of sand deposits in the Chungcheongnam-do erosion control dam built in 2010 confirmed an average deposit of 971.8m3. The sand deposit capacity and amount of sediment control for erosion control dams have a very low correlation with basin area or flow path slope, and this needs to be addressed in future sand deposit capacity designs.

N/A To determine the prevalence and risk factor of anti-HCV in ESBD patients under chronic maitenance hemodialysis, the prevalence of serum antibodies to hepatitis C Virus (Anti-HCV) was assessed by an enzyme immunoassay (Abbott HCV EIA) in 253 patients with long-term Hemodialysis in Daegu & Kyoungbuk. 15 patients (5.9%) were anti-HCV positive. All dialysis patients had the history of transfusion. The number of transfusion units was not significant in anti-HCV positive patients (mean 17±20 pints) in comparison with the number in anti-HCV negative patients (mean 16±17 pints). The frequency of hemodialysis was also not significant in anti-HCV positive patients (mean 477±618 ) compared with anti-HCV negative patients (mean 462±616). The mean duration of hemodialysis was significantly higher (p<0.001) in the anti-HCV positive patients (74±42 months) in comparison with anti-HCV negative patients (45±41 months). We concluded that the prevalence of anti-HCV in hemodialysis patients is 5.9% and that HCV infection is significantly mlated with the duration of hemodialysis rather than the number of transfusion units and the frequency of hemodialysis
