Optimal scan delay depending on contrast material injection duration in abdominal multi-phase computed tomography of pancreas and liver in normal Beagle dogs
Soo-Young Choi, In Lee, Ji-Won Seo, Hyun-Young Park, Ho-Jung Choi, Young-Won Lee 대한수의학회 Journal of Veterinary Science 7 Pages
대한수의학회 Journal of Veterinary Science 2016, 제 17권 제 4호 15 555-561 (7 pages)
This study was conducted to establish the values for optimal fixed scan delays and diagnostic scan delays associated with the bolus-tracking technique using various contrast material injection durations in canine abdominal multi-phase computed tomography (CT). This study consisted of two experiments employing the crossover method. In experiment 1, three dynamic scans at the porta hepatis were performed using 5, 10 and 15 sec injection durations. In experiment 2, two CT scans consisting of five... -

OFDM(Orthogonal Frequency Division Multiplexing) 및 SC-CP(Single Carrier with Cyclic Prefix) 방식은 문선 분야에서 각기 각광받고 있으며, 두 방식 모두 주파수 영역에서 효율적인 등화를 수행할 수 있는 장점을 지니고 있다. 무선 채널의 도플러 쉬프트 현상이 수반되는 경우 등화기만으로 온전히 왜곡 보상이 여의치 않을 수 있으며, 이에 따라 위상에러 추적회로와 등화기를 연동시켜 성능 향상을 도모할 수 있다. 본 논문에서는 평균위상에러의 효과를 기술하였고, 결정지향 방식의 평균위상 에러 추적회로와 proportional... -
The use of laser Doppler blood flow to assess the effect of acute administration of vitamin D on micro vascular endothelial function in people with diabetes

Objective: To assess the effect of vitamin D administration on the skin blood flow response to occlusion and heat. Design: Cross-sectional study. Methods: Twenty age matched subjects; 10 who had diabetes and 10 who were controls were administered 4,000 IU of vitamin D3 for 3 weeks at breakfast. The function of the endothelial cells was evaluated in 2 ways; first, the response to 4 minutes of vascular occlusion of the skin was measured with a laser Doppler flow meter. Second, the skin blood flow... -
Retrospective study of degenerative mitral valve disease in small-breed dogs: survival and prognostic variables

대한수의학회 Journal of Veterinary Science 2017, 제 18권 제 3호 14 369-376 (8 pages)
Small-breed dogs (n = 168; weight ＜ 15 kg) diagnosed with myxomatous mitral valve degeneration based on a routine clinical examination, radiology, electrocardiography, and echocardiography at the Seoul National University Veterinary Medical Teaching Hospital were included in this study. Survival periods were determined, and there were significant differences in survival rates among the three International Small Animal Cardiac Health Council classes. The mean follow-up period was 14.3 ± 12.1... -
Transrectal Doppler sonography of uterine blood flow during the first two weeks after parturition in Simmenthal heifers
Maike Heppelmann, Lars Krüger, Stephanie Leidl, Heinrich Bollwein 대한수의학회 Journal of Veterinary Science 5 Pages
대한수의학회 Journal of Veterinary Science 2013, 제 14권 제 3호 12 323-327 (5 pages)
Transrectal Doppler sonography was used to evaluate uterine blood flow during the first two weeks after parturition in six primiparous Simmental cows. The uterine blood flow was evaluated on the day of parturition (Day 0), once daily from Days 1 to 8 and then every other day until Day 14. Blood flow was quantified by determining the diameter (D), the time-averaged maximum velocity (TAMV), the pulsatility index (PI) and the blood flow volume (BFV) of the uterine arteries ipsilateral and...
