METHOD A survey of adolescents and parents (n = 72 adolescents, 72 parents) was performed assessing daily time spent on the Internet, television, console video games, and Internet video games, a...

We sought to develop and deploy a video-based smartphone-delivered mobile HIV Risk Reduction (mHIVRR) intervention to individuals in an addiction treatment clinic. We developed 3 video modules that consisted of a 10-minute HIVRR video, 11 acceptability questions, and 3 knowledge questions and deployed them as a secondary study within a larger study of ecological momentary and geographical momen...

BACKGROUND/AIMS Large clinical trials including patients with uncommon diseases involve assessors in different geographical locations, resulting in considerable inter-rater variability in assessment scores. As video recordings of examinations, which can be individually rated, may eliminate such variability, we measured the agreement between a single video rater and multiple examining physicians...

Different proposals have been made in recent years to exploit Social Web tagging data to improve recommender systems. The tagging data was used for example to identify similar users or viewed as additional information about the recommendable items. In this work we propose to use tags as a means to express which features of an item users particularly like or dislike. Users would therefore not on...

The video quality assessment must be adapted to the human visual system, which is why researchers have performed subjective viewing experiments in order to obtain the conditions of encoding of video systems to provide the best quality to the user. The objective of this study is to assess the video quality using image features extraction without using reference video. RMSE values and processing ...

Surgical simulation has the potential to enhance orthopaedic resident education. In this paper and associated video, we describe a module developed use teach trainees how perform pediatric proximal femoral osteotomies. Two module-specific evaluation tools, an Objective Structured Assessment of Technical Skills (OSATS) Checklist A Global Rating Scale Performance, are included. Detailed instructi...

this study involved 154 anesthetized patients requiring endotracheal intubation, in whom the epiglottis was visible but not lifted, which restricted the view of the glottis. a simple stylet was used to lift the epiglottis, thus improving the view of the glottis with the glide scope®, allowing tracheal tubes to be inserted into the patients. the stylet easily resolved the difficulty of lifting t...

Direct behavior rating (DBR) has been described as a hybrid of systematic direct observation and behavior rating scales. Although single-item (DBR-SIS) and multi-item (DBR-MIS) methods have been advocated, the overwhelming majority of research attention has focused on DBR-SIS. This study employed generalizability theory to compare the dependability of the two DBR methods for two behaviors (Acad...
