Introduction: Video games affect the stress system and cognitive abilities in different ways. Here, we evaluated electrophysiological and biochemical indicators of stress and assessed their effects on cognition and behavioral indexes after playing a scary video game. Methods: Thirty volunteers were recruited into two groups as control and experimental. The saliva and blood samples were collect...

OBJECTIVE This pilot study investigated whether a home exercise video programme could improve exercise tolerance and breathlessness in patients with moderate to severe chronic obstructive pulmonary disease. METHODS Twenty subjects completed the study after being randomized to intervention or control. The intervention group (n=10), watched a 19-min video on the benefits of exercise for patient...

There has been increased research interest in the use of active video games (in which players physically interact with images onscreen) as a means to promote physical activity in children. The aim of this review was to assess active video games as a means of increasing energy expenditure and physical activity behavior in children. Studies were obtained from computerized searches of multiple ele...

The ubiquity of video games in today's society has led to significant interest in their impact on the brain and behavior and in the possibility of harnessing games for good. The present meta-analyses focus on one specific game genre that has been of particular interest to the scientific community-action video games, and cover the period 2000-2015. To assess the long-lasting impact of action vid...

BACKGROUND This study examined whether mobile phone-based, one-way video messages about diabetes self-care improve hemoglobin A1c (A1C) and self-monitoring of blood glucose (SMBG). METHODS This was a 1-year prospective randomized trial with two groups. The active intervention lasted 6 months. The study enrolled 65 people with A1C >8.0% who were established (>6 months) patients in the endocrin...

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 ...

BACKGROUND There is a need for effective population-based physical activity interventions. The internet provides a good platform to deliver physical activity interventions and reach large numbers of people at low cost. Personalised advice in web-based physical activity interventions has shown to improve engagement and behavioural outcomes, though it is unclear if the effectiveness of such inter...

In this paper, we explore the technique of colorization for video compression. The chrominance of the intermediate frames is discarded during encoding. At the time of decoding, chrominance values, which are dropped, are approximated from colorizing grayscale frames by transferring color from a source color frame to a targeted grayscale frame. So far human intervention is an integral part of col...

BACKGROUND As infant disorganized attachment is a serious risk factor for later child psychopathology, it is important to examine whether attachment disorganization can be prevented or reduced. METHOD In a randomized intervention study involving 130 families with 6-month-old adopted infants, two attachment-based intervention programs were tested. In the first program, mothers were provided a ...

OBJECTIVE A group dissonance-based eating disorder prevention program, in which young women critique the thin ideal, reduces eating disorder risk factors and symptoms, but it can be difficult to identify school clinicians with the time and expertise to deliver the intervention. Thus, we developed a prototype Internet version of this program and evaluated it in a preliminary trial. METHOD Fema...
