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: This study aimed to examine the effects of maternal monitoring, shared activities with children, maternal education-oriented behavior, and allowing children to own smart-phones on smart media usage patterns based on smart-phone usage time and purposes among elementary school children. Methods: The participants were 1,315 second-grade elementary school children from the 9th wave of PSKC. Latent profile analysis and the three-step estimation approach were used to examine the determinants of the latent profile and the effects of maternal parenting on the profile. Results: Four latent profiles were identified: 'High-level usage & Entertaining oriented,' 'Moderate-level usage & Social/entertaining oriented,' 'Moderate-level usage & Learning oriented,' and 'Low-level usage.' Additionally, results showed that each profile can be predicted by maternal monitoring, education-oriented behavior, and permitting children to own smart-phones. Conclusion/Implications: Our outcomes suggested that it would be necessary to understand the smart media usage patterns of elementary school children, considering both the amount of time spent with smart media and purposes of uses. Further, it is helpful for mothers to monitor children's daily activities, support their educational activities, and take the role of gatekeeper for smart media as a way of appropriate guidance for their children's use of smart media.

This study examined the longitudinal effects of media usage by early school-age children and of maternal parenting stress on children's school adjustment. The study focused on the mediating effect of executive function difficulty. Longitudinal data to examine the hypothetical model were drawn from the eighth (2015) through tenth (2017) waves of the Panel Study of Korean Children (PSKC) collected by the Korea Institute of Child Care and Education (KICCE). A total of 581 children (293 boys and 288 girls) and their mothers were included. Confirmatory factor analysis, structural equation model, and bootstrapping analysis were applied using SPSS 25.0 and Amos 26.0. The results are as follows. First, no significant correlation was found between early school-age children's media usage and maternal parenting stress. Second, neither media usage by early school-age children nor maternal parenting stress were found to directly affect children's school adjustment. Third, media usage by early school-age children and maternal parenting stress were shown to indirectly affect children's school adjustment via executive function difficulties. In other words, higher levels of media usage by early school-age children and maternal parenting stress during the first grade lead to greater executive function difficulties after a year, which, in turn, lead to a lower level of school adjustment in the third grade. This study indicates the need to develop practical support for the psychological wellbeing of mothers while they are performing their role as a parent and for children in maintaining suitable levels of media usage during early childhood.

Social communications using information and communication technologies (ICT) for social interactions have been making a significant impact on task performance in organizations. However, most of the existing studies on ICT (e.g., telephone and email) have only focused on technical improvement of communication efficiencies (e.g., information exchange and storage). In this paper, we claim that ICT may be another alternative source of knowledge creation that enables employees to work, find solutions, and achieve their goals faster and better. We investigate the impact of ICT in terms of both tasks and social aspects with knowledge creation as task performance. Also, we investigate the moderating effect of media synchronicity on these relationships. This study contributes to the understanding of contemporary communications media usage and its performance in organizations. We collected and analyzed survey data of 248 company employees, using PLS. The results indicate that task urgency and social influence directly affect ICT usage, and even knowledge creation. Also the media synchronicity moderates the relationship between the characteristics of a given task and ICT usage and the relationship between ICT usage and knowledge creation. Theoretical and practical implications of these findings are also discussed in the paper.

Purpose - The purpose of this study is to investigate the relationship among narcissism, usage motives, usage behaviors, satisfaction with and continuance intention to use fashion social media. Research design, data, methodology - A questionnaire survey was used to collect data after conducting a pilot test. Based on the reliability test of the preliminary questionnaire used for the pilot test, the questionnaire was revised. The final questionnaires were administered to 238 fashion social media users and 216 were used for the data analysis. To assess the validity of these measures, exploratory factor analysis and the confirmatory factor analysis were performed. Structural equation modeling analysis were employed for data analysis. Results - Five factors of the usage motivation of fashion social media were extracted: information-seeking, relationship-seeking, practicality-seeking, enjoyment-seeking and self-expression motives. The statistical analysis confirmed the influence of the narcissism tendency on all of the usage motives of fashion social media, three of the fashion social media usage motives influencing information diffusion behavior, and the influence of the information diffusion behavior on users' satisfaction and continuance intention to use fashion social media. Narcissism exerted the highest influences on self-expression motive followed by information-seeking, enjoyment-seeking, relationship-seeking and practicality-seeking motives in order. Factors affecting fashion information diffusion behaviors are practicality-seeking motive, self-expression motive, and relationship-seeking motive. The greater the diffusion of information, the higher the satisfaction with using fashion social media. The consumers with higher satisfaction intended to use fashion social media and share information more frequently. Conclusions - The results indicate that narcissism is an important factor in fashion social media usage motivation. The main motives for narcissistic people to spread information is for the practical purpose at the most, and then to express their personality and style, and to build relationship with others. The satisfaction through active information sharing behaviors seems to play a key role to lead high continuance intention of fashion social media. These implies that marketing strategies to satisfy consumers' narcissism and motives to use social media, and to stimulate the information diffusion behaviors can be used to meet their needs for higher satisfaction with fashion social media.

미디어 융합 시대에 청소년들의 미디어 중독은 심각한 사회문제가 되기 시작하였고, 부모들은 올바른 자녀 양육을 위해 자녀들의 TV나 인터넷 사용을 제한하거나, 국가차원에서 다양한 정책 및 법률 등이 추진되어 왔다. 그러나 스마트폰이나 태블릿 PC 등 개인화된 미디어 장비가 보편화된 최근의 미디어 환경은 심화되는 중독 현상을 기존의 방법으로 과연 해결할 수 있는지에 대해 의문을 제기한다. 이에 본 연구에서는 가정 내 미디어에 통제가 청소년들의 미디어 이용 행태와 청소년들의 정서에 어떠한 영향을 미치고 있는지를 탐색적으로 살펴보았다. 884명의 10대 청소년들을 대상으로 분석을 수행한 결과 가정 내 미디어에 대한 통제 유무는 청소년들의 미디어 이용 시간에 유의한 영향을 미치지 않고 오히려 과도한 통제는 청소년들의 부정 정서 형성에 영향을 미치는 것으로 나타났다. 이러한 연구 결과는 최근 미디어 환경에서는 가정 내의 개별 미디어 이용 통제가 더 이상 효과적이지 않고 청소년들의 미디어 중독 예방을 위해 가정이나 국가 차원에서 새로운 노력이 필요함을 시사한다.

Adolescent media addiction has emerged as an important social agenda in Korea. However, there has not been enough discussion on the causal structure of media addiction and policy interventions. The objective of this study is to identify and assess the mechanism of the existing and the revised Shutdown policy based on the systems thinking approach. To achieve this purpose, we establish the relationship between media usage, flow, and addiction, and develop a causal loop diagram. Based on the causal loop diagram, we explore the causal structure of two policy scenarios: shutdown policy and deregulation. Our study suggests that policy interventions inducing direct parental control on children's media usage time are ineffective since the time control reduces children's autonomy, which helps alleviate media addiction. Therefore, this study suggests that policy intervention should focus on alleviating addiction itself rather than on controlling media usage time.
