OBJECTIVES Acceleration plethysmograms (APGs) are obtained by taking the second derivative of photoplethysmograms (PPGs) and are noninvasive circulatory signals related to risk factors for atherosclerosis with age. There has been growing interest in the development of mobile devices to collect and analyze PPG single features for ambulatory health monitoring. The present study aimed to extract a...

This study was conducted to assess adult female performance on the Southern California Visual Figure-Ground Perception Test (FGP) and to obtain an estimate of the test's reliability. Data were obtained for two scoring formats. The first format was the score for all items on the test (TOTAL), and the second format was the score through the fifth error (FIRST-FIVE). The mean scores were 38.24 (SD...

AIM To investigate the overall experiences of clinical pharmacy students during their clinical attachments and to understand the breadth and depth of clinical skills provided by their preceptors. METHODS A cross-sectional study using a self-administered questionnaire containing 34 items to obtain feedback from the clerkship students from June to July 2015. Data analysis was performed to calcu...

BACKGROUND Usually the researchers performing meta-analysis of continuous outcomes from clinical trials need their mean value and the variance (or standard deviation) in order to pool data. However, sometimes the published reports of clinical trials only report the median, range and the size of the trial. METHODS In this article we use simple and elementary inequalities and approximations in ...

The use of heart rate variability (HRV) parameters during exercise is not supported by appropriate reliability studies. In 80 healthy adults, ECG was recorded during three 6 min bouts of exercise, separated by 6 min of unloaded cycling. Two bouts were at a moderate intensity while the final bout was at a heavy exercise intensity. This protocol was repeated under the same conditions on three occ...

a watershed management program is usually based on the results of watershed modeling. accurate modeling results are decided by the appropriate parameters and input data. precipitation is the most important input for watershed modeling. precipitation characteristics usually exhibit significant spatial variation, even within small watersheds. therefore, properly describing the spatial variation o...
