Smart devices have a variety of affordances to foster meaningful learning in elementary school. For the design of smart learning environments, more research is needed to understand students' smart device usage and their perception of learning with smart devices. In order to capture smart device usage profiles among elementary school students in South Korea, this study carried out Latent Profile Analysis with three constructs: information search, communication, and study. Participants (n=253), who ranged from the fourth to the sixth grade students, were classified into three profiles of smart device usage: low-activity, communication, and high-activity groups. The smart device usage profiles varied depending on smartphone usage experience, and the profiles were significantly related with smart device addiction, not with smart device usage ability. Perceptions of smart education were also significantly associated with the profiles. The high-activity group showed more positive attitudes toward smart education than the others, but no significant difference was found in regard to negative attitudes. Based on the findings, this study discussed implications for the use of smart devices in elementary school.

As digital content services, especially OTT(over-the-top) video services, diffuse rapidly, so do smartTVs. Based on the indirect network effect theory and the complementarity theory, this study explores the relationship between digital content services and smartTV. Using the Media panel dataset, this study analyzes how the usage of digital content service (OTT usage, OTT usage volume, the usage of various OTT service types, and online game/music/education/news service) affects smartTV usage. This study shows that OTT usage and its usage volume is positively associated with smartTV usage, and that the usage of various OTT service types is positively associated with smartTV usage compared with non-OTT users. As for online content services, the usage of online education service is positively associated with smartTV usage while the usage of online news service is associated negatively. These results support the indirect network effect theory and the complementarity theory.

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.

This paper aims to analyse the factors influencing the implementation of smart factories and their performance after implementation, using the grounded theory analysis method based on interview data. The research subjects were 21 companies that were selected by the Smart Manufacturing Innovation Promotion Group under the SME Technology Information Promotion Agency in 2020-2021 as the best case smart factory implementation companies, and introduced the intermediate stage 1 or above. A total of 87 concepts were generated as a result of the analysis. We were able to classify them into 16 detailed categories, and finally derived six broad categories. These six categories are "motivation for adoption", "adoption context", "adoption level", "technology adoption", "usage effect" and "management effect". As a result of the overall structure analysis, it was found that the adoption level of smart factory is determined by the adoption motivation, the IT technology experience affects the adoption level, the adoption level determines the usage and usage satisfaction, internal and external training affects the usage and usage satisfaction, and the performance or results obtained by the usage and usage are reduced defect rate, improved delivery rate and improved productivity. This study was able to derive detailed variables of environmental factors and technical characteristics that affect the adoption of smart factories, and explore the effects on the usage effects and management effects according to the level of adoption. Through this study, it is possible to suggest the direction of adoption according to the characteristics of SMEs that want to adopt smart factories.

Smart TV is rapidly growing with the provision of OTT services, and has become an alternative to pay-TV services. Yet smart TV in Korea has been diffused slowly, and thus few research has paid attention to smart TV. With the global growth trend of smart TV, research on smartTV, focusing on users' characteristic and their behaviors, is critical to explain smart TV's usage. To employ the Mediapanel dataset, this study explores the impact of smart TV users' demographic factors and their pay-tv usage on smart TV usage. The results suggested that age, the type of household, household income, and market size are associated with smart TV usage. Pay-TV usage, specifically IPTV subscription and VOD expenses, have impacts on smart TV usage. Lastly the interaction effect between IPTV subscription and movie VOD expenses, has negatively associated with smart TV usage. This study may bring to re-attention to smart TV and to give insights into the industry field.

The purpose of this study is to investigate the user's attitude and usage of smart banking application in terms of user's benefits and personalization. While the prior researches on mobile banking adoption focus on the characteristics of service itself, this paper intends to investigate the smart banking application in terms of user's benefits, which are personal value consumers attach to the product or service attributes. Based on prior studies functional benefits, social benefits, experiential benefits, and personalization are identified as affecting factors of the user's attitude and usage of smart banking application. According to the results of multiple regression analysis, all benefit factors(functional benefit, experimental benefit, social benefit) and personalization were found to be significantly related to the user's attitude. Users' attitude on smart banking was found to be significantly related to the real usage as well. This paper has value in that it investigates the attitude and usage of smart banking in terms of benefits.

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.

The purpose of this study was to examine the pathways between mothers' inappropriate smart device usage habits, preschoolers' immersion tendency and self-regulation, and children's cognitive ability. The subjects of the study were 308 preschoolers aged 4 and 5 years and their mothers in Seoul, Gyeonggi-do, Incheon, Gangwon-do, Daejeon, Busan, and Mokpo. Data were analyzed with descriptive statistics, t-test, one-way ANOVA, and Pearson correlation using the SPSS 25 program. A sequential mediation model was analyzed using the AMOS 22 program. Mothers' inappropriate smart device usage habits were found to have a negative effect on the preschoolers' self-regulation, and this association was mediated by the preschoolers' smart device immersion tendency. These findings show the mechanisms through which mothers' inappropriate smart device usage habits negatively affect preschoolers' smart device immersion and self-regulation which, in turn, has a negative impact on cognitive ability
