This study analyzes the previous literature on the online safety of children and youth under “the 4Cs risk framework” concerning contact, content, conduct, and contract risks. It then conducts a comparative study of Australia, Canada, and the UK, comparing their institutions, governance, and government-led programs. Relevant research in Childhood Education Studies is insufficient both in quantity and quality. To minimize the four major online risks for children and youth in cyberspace, it is necessary to maintain a regulatory approach to the online exposure of children under the age of 13. Moreover, the global society should respond together to these online risks with “multi-level” policymaking under a “multi-stakeholder approach”. At the international level, multilateral discussion within the OECD and under UN subsidiaries should continue to lead international cooperation. At the domestic level, a special agency in charge of online safety for children and youth should be established in each country, encompassing all relevant stakeholders, including educators and digital firms. At the school and family levels, both parents and teachers need to work together in facilitating digital literacy education, providing proper guidelines for the online activities of children and youth, and helping them to become more satisfied and productive users in the digital era.

This study examined two subfactors of fundamental movement skills: locomotion skills and object-control skills. The direct and indirect effects of children’s temperament on fundamental movement skills and the mediating effects of autonomy and self-regulation were examined. Participants included 278 pairs of 3- to 5-year-old children and their mothers from 4 day care centres. High levels of emotionality and sociability were positively associated with a high level of children’s autonomy, self-regulation and fundamental movement skills. There was a mediating effect of children’s autonomy and self-regulation on the effect of temperament on locomotion skills, but there was no mediating effect on object-control skills. The results provide empirical evidence of holistic development by confirming that temperament is a variable that affects gross motor development and that children’s psychological development is related to motor development.

This study addresses the novel concept of two types of parental academic support (PAS), namely, as a companion and as a manager, and identifies the effect of children’s perceived PAS on their psychological attributes and academic achievements. The data include a nationally representative sample of 6836 students from the Korean Education Longitudinal Study 2013. A correlation analysis showed that the two types of PAS had a positive relation with adolescents’ development; however, a structural equation model showed a negative effect of PAS as a manager. Children’s perceived PAS as managers had no effect on their self-regulation or academic achievement after 3 years, surprisingly, was found to increase their amotivation. Children’s perceived PAS as companions had a long-term, positive effect on adolescents’ development and academic achievements. The results suggest that parents should recognize their children’s autonomy and provide academic support on an equal level. Further multidimensional PAS studies should be conducted with more detailed questions.

This study was conducted to identify the relation between children’s autonomy and motor development mediated by teacher–child relationships. Are there differences between teacher–child relationships and motor development according to the gender of the child? To answer this question, the fundamental movement skills of 292 children were measured, and teacher–child relationship and children’s autonomy data were collected from the teachers. There was a gender difference in locomotion skills; however, there was no difference in object control skills. In the case of girls, a conflict teacher–child relationship mediates the association between autonomy and object control skills. This study highlights the importance of teacher–child relationships, which are mainly discussed in relation to conventional social-emotional development, and provides examples of whole-child development.

This review paper addresses the growing and increasingly sophisticated issue of cyber sexual crimes targeting children and adolescents. It explores specific examples of various sexual offenses, analyzes the limitations of current legal frameworks, and offers practical recommendations for prevention. As one of the world’s most advanced digital societies, South Korea has witnessed a significant rise in such crimes. These incidents are classified into clear criminal acts, tactics used to lure minors, and occurrences within virtual environments, all of which should be integral to educational programs for children and parents. This study also examines the UK’s Online Safety Act, recognized as a leading model in combating online sexual offenses, and highlights the deficiencies in South Korean law. Given that these crimes often extend into the offline world, exploit vulnerable groups with increasing subtlety, and are challenging for individuals to counteract alone, there is a critical need for specialized education for minors, metaverse training for parents, and the enhancement of both legal measures and international cooperation in this area.
