Problem statement: Electronic learning (e-learning) System is an ideal example of these modern learning options. It provides reliable, convenient and easily accessible environment of learning. Since the e-learning is now growing in King Saud University, this new learning approach has to be evaluated and monitored to measure the efficiency and ultimately improves its productivity. The monitoring...

BACKGROUND AND AIMS The influence of sociobiological variables and aging on the variability of the Trail Making Tests (TMT), the Symbol Digit Substituting Test (SDT), and the Line Trait Test (LTT) in the general healthy populations are not well known. Even less is known about the reliability at re-testing. This study aimed at determining the reference range of these tests, taking into account s...

Weaning from mechanical ventilation remains a major challenge for critical care physicians. Because subjective criteria are inaccurate, objective measurements consisting of clinical criteria and physiologic tests (weaning predictors) have been used to facilitate decision-making. An integrated weaning index calculated as the product of static compliance and arterial oxygen saturation divided by ...

OBJECTIVE To determine the intention to use hearing aids (HAs) by applying the theory of planned behavior (TPB). DESIGN The TPB is a widely used decision-making model based on three constructs hypothesized to influence the intention to perform a specific behavior; namely, "attitude toward the behavior", "subjective norm", and "behavioral control". The survey was based on a TPB-specific questi...

Optimal timing [1;2] has long been recognized as an important criterion for decision-making in the absense of uncertainty. Since the late Seventies, competition in the aviation industry in an effort to secure landing rights, nonscheduled flights and new gateways opens up a new chapter on the techniques of selling activities. Firms whose selling activities confront with unexpected difficulties m...

Background and study aims: Colonoscopy with portal inhaled methoxyflurane (Penthrox) is highly feasible with low sedation risk and allows earlier discharge. It is unclear if subjects can return to highly skilled psychomotor skill task shortly after Penthrox assisted colonoscopy. We evaluated the psychomotor and cognitive effects of 15-minute inhalation of Penthrox in adults. Patients and method...

The aim of the study was to assess the group 24-h pattern of lag time (LT) in response by regular and volunteer firemen (RFM and VFM) to calls for medical help (CFMH), specifically calls for out-of-hospital cardiac arrest (OHCA). LT, duration in min between a CFMH and departure of service vehicle equipped with a semiautomated defibrillator and generally staffed with four well-trained and ready-...

Selective attention and efficacy are important components of scholastic performance in school children. While attempts are being made to introduce new methods to improve academic performance either as part of curricular or extracurricular activities in schools, the success rates are minimal. Hence, this study assessed the effect of yoga-based intervention on psychomotor performance and self-eff...

Johnson describes the lack of reproducibility of scientific studies, attributed, according to the author, to the low level of significance (1). We appreciate the quality of this work and its importance for the interpretation of statistical evidence. These results should be considered in statistical guidelines. Nevertheless, we would like to point out some important points not thoroughly discuss...

BACKGROUND Although measures of knowledge translation and exchange (KTE) effectiveness based on the theory of planned behavior (TPB) have been used among patients and providers, no measure has been developed for use among health system policymakers and stakeholders. A tool that measures the intention to use research evidence in policymaking could assist researchers in evaluating the effectivene...
