  • This study aimed to examine the effect of the depression on fatigue among university students by mediating smartphone overuse, which would be expected to help to lead healthy school life. Participants were composed of the 193 university students and performed a self-report questionnaire including depression, fatigue, smartphone overdependence, and demographic characteristics. Data was analyzed using SPSS 25.0 along with the PROCESS macro program. The main findings were as follows. Depression had a significant effect on fatigue among university students (F=8.180, p<.001), and smartphone overdependence was significantly mediated between depression and fatigue (B=.120, p<.001). These findings suggest that psychological aspects should be considered when developing intervention programs aimed at reducing fatigue levels of university students. Furthermore, the efforts to appropriate use of smartphones are needed.

  • The purpose of this study was to investigate the standardization of daily average smartphone use time among adolescents. The data were analyzed using the data from Korea youth risk behavior web-based survey of 2017, and the total number of students analyzed was 54,603. Frequency analysis, independent t test, Pearson correlation analysis, and one-way ANOVA were used for statistical analysis. As a result, the correlation coefficient between smartphone use time, age, and grade was very low (r =.025~.039). There was no significant difference in the usage of smartphone between middle and high school students(p>.05). Time of smartphone use was significantly higher in middle school students as the grade increased(p<.05). In high school students, second-year students had significantly more smartphone usage than first and third grade students(p<.05). The researchers described 54603 adolescents' average(minute) daily smartphone usage about sex(male, female), period of use(weekday, weekend), school(middle school, high school), and grade(first, second, third) as a 7th quartile. We suggest that the standard value of smartphone use time can be used as a basis for the physical and mental health management in adolescents. It is necessary to present a standard value that can prove the future overuse of smartphone.

  • Objective: This study examined the mediating roles of preschoolers' self-regulation in the relationship between maternal parenting behaviors and preschoolers' excessive immersion in smartphones. Methods: A total of 268 mothers of preschoolers responded to questionnaires on three research variables. Data were analyzed by correlation analyses and regression analyses. Results: First, maternal warmth/encouragement was negatively related to preschoolers' excessive immersion in smartphones, while maternal overprotectiveness/permission and rejection/neglect were positively related to preschoolers' excessive immersion in smartphones. Second, maternal warmth/encouragement and limit setting were positively linked to preschoolers' self-regulation, but maternal overprotectiveness/permission and rejection/neglect were negatively linked to preschoolers' self-regulation. Third, preschoolers' self-regulation was negatively associated with their excessive immersion in smartphones. Finally, preschoolers' self-regulation fully mediated the relationship between maternal warmth/encouragement and preschoolers' excessive immersion in smartphones, and preschoolers' self-regulation partially mediated the relationship between maternal overprotectiveness/permission, rejection/neglect and preschoolers' excessive immersion in smartphones. Conclusion/Implications: The results of this study suggest that positive maternal parenting behaviors and preschoolers' effective self-regulation are important in order to decrease preschoolers' smartphone overuse. These findings provide empirical evidence to develop programs for prevention and intervention of preschoolers' smartphone addiction.

  • The aim of this study was to identify the relationship between smartphone usage time and oral health among Korean adolescents using data from the 13th (2017) Korea Youth Health Behavior Survey, which included 62,276 subjects. The daily smartphone usage time was categorized as not used, less than 2 hours, more than 2 hours, less than 4 hours, and more than 4 hours. Our results reveal that 60.1% of participants and 61.7% of smartphone users experienced oral disease symptoms annually, 27.4% of total adolescents used smartphone more than 4 hours daily during weekdays, and 53.8% more than 4 hours daily on weekends. The results from multivariate logistic regression analysis adjusting general characteristics show that the adjusted odds ratio (aOR) for risk of oral disease experience was 1.78 (95% confidence interval, CI 1.67-1.91) times higher in the group that used smartphones more than 4 hours a day on weekdays and 1.81 (95% CI 1.70-1.93) times higher in the group that used smartphones more than 4 hours a day on weekends compared to the group that did not use smartphones. The results indicate that smartphone overuse among Korean adolescents has a harmful effect on oral health. Education programs for reducing excessive use of smartphones among adolescents will help promote oral health.
