The efficacy of video recording in transmitting clinical knowledge and skills to medical students was tested by recording on videotape demonstrations of physical examinations given by five clinicians to a randomly selected group of 12 students (personal group) from the first clinical year and then showing these recordings, under identical conditions, to 13 students from the same year (video gro...

PURPOSE The quality of problem representation is critical for developing students' problem-solving abilities in problem-based learning (PBL). This study investigates preclinical students' experience with standardized patients (SPs) as a problem representation method compared to using video cases in PBL. METHODS A cohort of 99 second-year preclinical students from Inje University College of Me...

This paper define a spatiotemporal mutual information on the pixels of a given video image on the basis of information theory (Shannon’s communication theory), which can be interpreted as the theoretical estimation of interested spots for human being. As an application of this spatiotemporal mutual information, we propose a method of producing a vivid video image of the distance learning by usi...

A vioient virtuai-reaiity (VR) video game's short-term impact on telepresence and hostility was studied. Five weeks before a lab experiment, participants completed a questionnaire measuring prior vioient video game use and trait aggression. Participants were randomly assigned to play a VR vioient video game, play a standard vioient video game, observe a vioient video game, or observe a non-vioi...

In this paper, we propose a new full-fuzzy video ratecontrol algorithm (RCA) for variable bit rate (VBR) videoapplications. The proposed RCA provides high qualitycompressed video with a low degree computational complexity.By controlling the quantization parameter (QP) on a picturebasis, it produces VBR video bit streams. The proposed RCAhas been implemented on the JM H.264/AVC video codec andth...

BACKGROUND Two trials were conducted to compare emergency department patient comprehension of rapid HIV pre-test information using different methods to deliver this information. METHODS Patients were enrolled for these two trials at a US emergency department between February 2005 and January 2006. In Trial One, patients were randomized to a no pre-test information or an in-person discussion a...
