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.
This study analyzes the effects of smartphone overdependence and the quality of friendship on depression among high school students in Korea. The study subjects were 121 high school students. Smartphone overdependence was assessed using the smartphone overdependence scale for adolescents, depression was assessed using the Korean version of the patient health questionnaire-9, and the quality of friendship was assessed using the friendship quality questionnaire. The results of the correlation analysis showed statistically significant differences among all the variables. The results of the multiple linear regression analysis showed that smartphone overdependence increases the depression level, whereas the quality of friendship lowers it. To decrease depression among high school students, smartphone overdependence and the quality of friendship should be managed appropriately. Moreover, the causal relationships and mediating effects between smartphone overdependence and the quality of friendship should be analyzed.
Objective. This study is aimed at providing baseline data for improving the social participation of persons with visual impairment by verifying the impacts of daily life satisfaction and job satisfaction on their social participation. Methods. This study utilized data from the 5th survey of the 2nd wave of the Panel Survey of Employment for the Disabled (PSED) provided by the Korea Employment Agency for Persons with Disabilities (KEAD). Of the 511 persons with visual impairment who participated in the panel survey, 151 people who met the inclusion criteria were selected as the research subjects. This study compared social participation, job satisfaction, and daily life satisfaction, which were validated by experts’ review, consulting, and research at the KEAD. Results. Daily life satisfaction and job satisfaction of persons with visual impairment had positive correlations with social participation. Job satisfaction had a statistically significant impact on social participation. Additionally, the stability of employment and monthly income were the variables affecting social participation. Conclusion. The result drawn in this study can be applied as basic data related to the social participation of people with visual impairment.
