(1) Purpose: In modern society, augmented reality (AR)-based training using a smart device has emerged as a means of resolving problems with training. Thus, this feasibility study aimed to identify the effects of tooth-brushing training, based on AR using a smart toothbrush, on oral hygiene care among people with an intellectual disability in Korea. (2) Methods: Thirty people with an intellectual disability, residing in a residential care facility, were selected. Tooth-brushing training based on AR, using a smart toothbrush, was applied in the experimental group (n = 15), and training using visual material was applied in the control group (n = 15). As an assessment of oral hygiene care, the changes in tooth-brushing performance and oral hygiene were measured. (3) Results: There were significant differences in all results after training between the two groups, (4) Conclusions: Tooth-brushing training based on AR using a smart toothbrush is more effective than training using visual material on oral hygiene care among the subjects of this feasibility study. Thus, training based on AR using a smart toothbrush could be applied to people with intellectual disabilities residing in residential care facilities as an individual tool for tooth-brushing training.
Purpose:The purpose of this study was to provide basic information about the analysis of the correlation between online friendship network and internet game disorder among university students.Methods: Study subjects were 77 university students. For analysis of online friendship among them, social network analysis was performed and the analysis of degree, closeness, and betweenness centrality was measured. Assessment of internet game disorder was done using the Korean version of Internet Gaming Disorder Scale.Results: As per the results, the positive correlation showed between in-closeness centrality and internet gaming disorder (IGD) and the negative correlation showed between out-closeness centrality and internet gaming disorder.
Conclusions:Online friendship is considered to contribute to the changes of internet game disorder level. Thus, in the relationship between online friendship and internet game disorder, closeness centrality should be considered, and causal relation analysis should be performed in further studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
