This paper presents a VR-based ILE, which integrates virtual reality (VR) technology into interactive learning environment (ILE). It is said that ILE is composed of Intelligent Tutoring System (ITS) and micro world. ILE supports a student's discovery learning activity and fosters his/her creativity and adaptability. Moreover, we integrate VR technology into ILE and build discovery learning envi...

Virtual Reality (VR) has emerged as one of the important and effective tools for education and training. Most VR-based training systems are situation-based, where the trainees are trained for discrete decision-making in special situations presented by the VR environments. In contrast, this paper discusses the application of VR to a different class of training, for learning motions, often requir...

The current serological typing scheme for Neisseria meningitidis is not comprehensive; a proportion of isolates are not serotypeable. DNA sequence analysis and predicted amino acid sequences were used to characterize the structures of variable-region (VR) epitopes on N. meningitidis PorB proteins (PorB VR typing). Twenty-six porB gene sequences were obtained from GenBank and aligned with 41 new...

BACKGROUND/AIMS Decay of hepatitis B surface antigen (HBsAg) titers has previously been shown to be predictive of a virologic response (VR), especially during peginterferon-alpha therapy. However, the role of HBsAg levels in predicting a VR to nucleos(t)ide analog therapy has not yet been established. In this study we sought to determine whether the VR can be predicted from HBsAg titers in nucl...

The feeling of presence in a virtual reality (VR) is a concept without a standardized objective measurement. In the present study, we used event-related brain potentials (ERP) of the electroencephalogram (EEG) elicited by tones, which are not related to VR, as an objective indicator for the presence experience within a virtual environment. Forty participants navigated through a virtual city and...

People tend to respond realistically to situations and events in immersive Virtual Reality (VR). Our research exploits this finding to test the hypothesis that the psychology underlying moral judgement is distinct from the psychology that drives moral action. We have conducted an online survey study with 80 respondents on people’s judgments of moral dilemmas. Additionally, we have carried out a...

Presentation of social situations via immersive virtual reality (VR) has the potential to be an ecologically valid way of assessing psychiatric symptoms. In this study we assess the occurrence of paranoid thinking and of symptoms of posttraumatic stress disorder (PTSD) in response to a single neutral VR social environment as predictors of later psychiatric symptoms assessed by standard methods....

Since the late 1990s the use of virtual reality (VR) has expanded in the field of mental disorders. During this time, several VR-based applications have been developed for the treatment of eating disorders (ED) and obesity. Both these pathologies involve disturbances related to eating behavior, weight, and body image. Although effective and well-established protocols are now available for the t...

Virtual reality VR is emerging as an important approach to the mod eling and simulation of complex systems But software technology for scientists to build VR based applications fosters development of closed applications each built from scratch A scientist s ability to merge models and systems once developed is solely dependent upon their ability to hack software since the principles of VR syste...

PURPOSE/OBJECTIVES To explore virtual reality (VR) as a distraction intervention to relieve symptom distress in adults receiving chemotherapy treatments for breast, colon, and lung cancer. DESIGN Crossover design in which participants served as their own control. SETTING Outpatient clinic at a comprehensive cancer center in the southeastern United States. SAMPLE 123 adults receiving initi...
