Hot carrier 현상으로 인한 0.8㎛ RF NMOSFET의 성능저하 현상을 일반적인 소자 열화 메커니즘을 이용하여 분석하였다. 게이트 finger가 하나인 기존의 소자 열화 모델을 게이트가 multi finger인 RF NMOSFET에 적용할 수 있었다. Hot carrier 스트레스 후의 차단 주파수와 최대 주파수 감소 현상은 transconductance 감소와 출력 드레인 전도도의 증가로 해석할 수 있었다. Hot carrier로 인한 DC 특성 열화와 RF 특성 열화의 상관관계를 구하였으며 이를 이용하여 DC 특성 열화를 측정하므로 RF 특성 열화를 예측할 수 있게 되었다. -

Objective: To investigate the effect of long-term water exercise on gait parameters in the elderly post stroke patients. Design: One group pretest-posttest design. Methods: Twenty elderly post stroke patients (age: 56.5±10.1 years, height: 168.6±5.8 cm, body mass: 69.3±6.9 kg, handicapped level: 2.5±0.8) participated in this study. Participants took part in gait training of 1 hour per day, three days per week, for three months. Participants’ gaits were analyzed to find the effect of 3... -

Bronchoalveolar lavage (BAL) and thoracic radiography are routinely performed diagnostic procedures. We hypothesized that BAL increases the interstitial opacity of caudoventral and caudodorsal thoracic radiographs. Fifty-three horses, including 8 clinic owned and 45 from a referral hospital population, were classified as healthy controls (n = 12), severe equine asthma (recurrent airway obstruction, n = 12) or mild-to-moderate equine asthma (inflammatory airway disease, n = 21) based on the... -

Appropriate hoof preparation and symmetry are linked to the well-being of the horse. Previous studies have shown the efficacy of pressure plates (PPs) in delivering objective biomechanical analysis. We aimed to assess the effect of hoof trimming on hoof biomechanics using a PP. Nine clinically sound Arabian horses were walked across a PP while foot strike was recorded by a digital camera. Kinetic and kinematic parameters were recorded before and after trimming. Changes were considered... -

The objective of this study was to compare ovulation rate, number of large ovarian follicles, and concentrations of plasma progesterone (P4) and non-esterified fatty acids (NEFA) between lame (n = 10) and non-lame (n = 10) lactating Holstein cows. The study was conducted in an organic dairy farm, and cows were evaluated by undertaking ultrasonography and blood sampling every 3 days from 30 days postpartum for a period of 34 days. Cows which became lame during the first 30 days postpartum... -

The objective of the present study was to monitor and characterize morphological alterations in ovaries of agouti (Dasyprocta prymnolopha), reared in captivity, by using abdominal ultrasonography. All animals underwent daily vaginal cytological examination to identify the current cycle phase. For each phase of the estrous cycle, ultrasound examinations were carried out to identify and describe the morphology of both ovaries. Topographic parameters in an ultrasound window were established to...
