This study aimed to investigate the mediating effect of the screen media time of young children on the relationship between mothers' reasons for allowing young children to use screen media and their children's ability to regulate screen media. The participants consisted of 614 children aged 5-6 (312 boys and 302 girls), and all the survey questions were answered by their mothers. Descriptive statistics, Pearson's correlation, structural equation modeling, and bootstrapping analysis were employed to analyze the data using SPSS 25.0 and Mplus 8.6. The results were as follows. First, mothers' educational and ritualized reasons for allowing young children to use screen media and children's screen media time directly affected young children's ability to regulate screen media. Second, children's screen media time mediated the relationship between mothers' educational and ritualized reasons for allowing their children to use screen media and children's ability to regulate screen media. When mothers permitted their children to use screen media for educational purposes, their children were likely to spend less time on screen media usage which, in turn, increased their ability to regulate screen media. Conversely, the more mothers allowed their children to use screen media for ceremonial purposes, the more time their children spent on screen media and the less ability they had to regulate screen media usage. These outcomes suggest that, to improve children's screen media regulation ability, mothers must not routinely allow their children to use screen media and should manage their children's screen media time.

Smartphones are representative multimedia devices capable of various functions that have emerged due to the development of information communication technologies (ICTs). The popularization of smartphones has changed the way ICTs media is used; consequnetly, it is expected that smartphones will influence family life by changing family communications and time use. However, there is a gap between the empirical research on ICTs media and family. This study explores any correlations in the amount of time spent on smartphones between a husband and wife. We marged 1,444 married couples' media diaries from the 8th Korean Media Panel Survey (2017) to analyze the average amount of time spent on communications and leisure shopping using smartphones. The results show that husbands' time use for communication has increased similarly to wives' time use. In addition, husbands' time use for leisure and shopping was positively related to wives' time spent on communications and leisure shopping. The findings show that the use of smartphones is interrelated within the family and suggested that a family systems approach is needed in ICTs media research. Future studies will provide a deeper understanding of the impact of ICTs media and how families are using a variety of ICTs media devices such as smartphones.

Purpose: The purpose of this study was to identify the influence of parental media use, parents' educational needs regarding media use, and parents' media guidance for children on the children's media use. Methods: The participants were 161 parents of elementary school children in the 1st and 4th grades. Data were collected through self-report questionnaires, and analyzed using the SPSS/WIN 19.0 IBM program. Results: The average times for watching television and using the internet in the children were 11.44 hours and 5.89 hours per week, respectively. Children's time watching television was influenced by parents' time watching television, children's gender (girl), and parents' educational needs. Children's television dependency was influenced by parents' educational needs, parents' time watching television, and parents' age (under 36 years). Time using the internet and internet dependency in the children were influenced by parents' educational needs, family monthly income (under 3 million won), and parents' guidance for children on watching television. Conclusion: The findings indicate that elementary school children's media use is influenced by parental media use, parents' educational needs, and parents' media guidance for children. Therefore parental factors should be considered in developing approaches to provide education programs to prevent media overuse in children.

Objectives: Screen time refers to the time spent using screen media, such as televisions, smartphones, computers, or tablets. Excessive exposure to screen media has been reported to negatively impact young children's health and development, including overweight, short sleep duration, and language delays. This study examined the association of screen time and mealtime media use with dietary behaviors among preschool children. Methods: A cross-sectional survey was conducted on parents of children aged three to five years using the online questionnaires of the Nutrition Quotient for Preschoolers (NQ-P) and the Dietary Screening Test (DST). Data from 261 children's parents were analyzed. Results: Of the 261 children, 96.9% used screen media, 55.6% used screen media for two hours or more daily, and 30.7% were exposed to screen media during meals. The NQ-P scores were significantly lower in the children with longer screen time and mealtime media use. Children who used screen media for two hours or more and those exposed to screen media during meals consumed kimchi less frequently and confectionery and sugar-sweetened beverages more frequently than children who used less than two hours and were not exposed to screen media during meals. In addition, they were more likely to be picky about food, refuse to eat, and less likely to feed themselves than children with shorter screen time and no mealtime media use. Conclusions: This study reported an association between unhealthy dietary behaviors, feeding difficulties, and screen time and mealtime media use among preschool children. Further research should explore effective strategies for reducing children's screen time.

This research observes how an adolescent's usage of social network services is related with media use time, and also tries to verify how a parent's participation in acting to limit usage time serves as a mediating effect. For this analysis, data from The Korean Information Society Development Institute [Korea Media Panel Research] was used, being a survey conducted on 1,572 students from primary to secondary and high schools nationwide. The subjects' gender in the final analysis was 818 male students and 754 female students. In addition, primary school students consisted of 672 individuals, 416 were from secondary and 484 from high schools. To verify the appropriateness of the model proposed in this research, analyzed through the structural equation, using social network services(SNS) was not shown to have an effect on media usage time. However, there was an indirect effect from the use of alternative activities. In addition, the parent's limitation of usage showed no effect on media use time. This research attempts to identify the reasons why parents' limiting the usage time, along with alternative activities, do not have any significant effect in reducing media usage time in this era of smart media evolution. Further, this research hopes to suggest meaningful and political implications for the nation and society to understand and resolve media addiction.

This study investigated the relationship between preschoolers' smart media usage in regards to cognitive and language development, especially the mediating effect of preschoolers' smart media addiction tendency and the moderated mediating effect of maternal guidance on smart media usage. The study surveyed 273 preschoolers' mothers who lived in Daegu City and Kyungpook Province. The findings of this study were as follows. First, preschoolers' smart media addiction tendency mediated the relationship between smart media usage time in regards to cognitive and language development. Second, maternal active mediation and monitoring moderated the relationship between preschoolers' smart media usage time and smart media addiction tendency. Third, there was a maternal co-use moderated the mediating effect of preschoolers' smart media addiction tendency on language development. In conclusion, preschoolers' smart media addition tendency mediated the effect of smart media usage time on cognitive and language development. Among the mediation pathways, the influence of preschoolers' smart media addiction tendency on language development was moderated by maternal co-use. The findings of this study suggest that maternal guidance should be applied differently depending on preschoolers' smart media addiction tendency. This study examined preschoolers' and maternal smart media-related variables on preschoolers' cognitive and language development in order to provide preliminary data that can be used to explore the maternal guidance on how to use smart media for their preschool children.

Objective: The present study examined long-term effects of media use during early childhood on grit in middle childhood, focusing on the mediating role of attention problems. Methods: For statistical analysis, the 6th, 7th, and 11th data sets from the Panel Study on Korean Children were used. A total of 1,352 cases were finally selected. Descriptive statistics analysis, correlation analysis, path analysis, and bootstrapping were conducted. Results: The results showed that the use of media for educational purposes in early childhood did not have a significant effect on attention problems and grit. However, when the media use time for play in early childhood was longer, levels of attention problems in early childhood were higher and levels of grit in middle childhood were lower. The mediating effect of attention problems on the relationship between media use time for play of young children and grit of middle childhood was significant. Conclusion/Implications: Findings of the present study suggest that the use of media for play during early childhood needs to be carefully monitored because it can have a negative effect on attention and grit development.

Purpose: The purpose of this study was to identify the correlation between the motivations to use social media and self-control among female middle school students. Methods: This study is a cross-sectional descriptive study. To collect the data, 300 female students of S and E middle school in S city responded to a self-administered questionnaire asking about their motivation for social media use and self-control. The data were analyzed through descriptive statistics, independent t-test, one way ANOVA, Scheffétest, Pearson's correlation, and stepwise multiple regression, using the SPSS/WIN 21.0 program. Results: The average time spent on social media was 3.70 hours. The mean scores of social media usage motivation and self-control were 48.15 and 58.47, respectively. The more average time spent on social media, the higher was the motivation to use social media. The scores of motivation to use social media were higher in students with low satisfaction of their school and family life. Students with low satisfaction of their school life had higher scores in some subcategories of self-control; preference to simple task, egocentrism, and stroppiness. Motivations to use social media showed a significant positive correlation with self-control. Self-control was affected by motivations to use social media and this variable explained 11.6% of self-control among female middle school students. Conclusion: The results of this study suggest that we should develop programs which help improve students' self-control and prevent the side effects of social media use among female middle school students.

This study tries to test time reallocation hypothesis proposed by Lee(2005) that claims the time use pattern as a whole has changed as new media is introduced-in this case, internet-in our daily lift. It has been pointed out that researches, confined to study whether time use for traditional media is displaced by a new media, have such a limitation as 'media isolationism' and resulted in incoherent conclusions. In order to verify time reallocation hypothesis, which explains the influence of internet use on daily activities with broad perspectives, this research employed two different methods. First, this study analyzed the differences of time use patterns of daily activities and media use behaviors between internet users and non-users by using t-test. Second, logistic regression was used to confirm that the difference of time use pattern between internet users and non-users in many daily activities. The results show that time use pattern for daily activities has reorganized In the most of the age groups. Especially, in the young age groups, time reallocation by internet appeared more obvious than the equivalent old age groups.
