Objective: The purpose of this study is to identify and prioritize sub-goals for infants and young children among the Korean Sustainable Development Goals (K-SDGs). Methods: The expert panel of this study consisted of 15 faculty members from the department of early childhood education or children's studies at 12 universities and was put together in order to conduct a Delphi survey. Results: As a result of the study, first, a total of 16 sub-goals were developed in order to target infants and young children. Second, the 16 sub-goals were then ranked according to their importance and urgency, and the most important goal were 'the improvement of mental health and prevention of drug abuse (K-SDG 3-2)'. And 'the elimination of violence and discrimination against girls (K-SDG 5-1, 5-2)', 'the safe and inclusive learning environment (K-SDG 4-8)' and 'end of abuse, trafficking, exploitation and all forms of violence against children (K-SDG 16-2)' were the next important and urgent goals. These priority objectives reflect the inviolable rights that infants and young children in Korea should be guaranteed by default. Conclusion/Implications: This study provided a basis for its effective implementation by identifying goals and priorities for infants and young children in comprehensive and interdependent K-SDGs.

Objective: The purpose of this study was to examine how job stress, coping style, and social support were associated with quality of life among child care teachers. Methods: The participants were comprised of 281 child care teachers in the metropolitan area of Seoul. Job stress, problem-focused coping style, social support, and quality of life were assessed by a teacher-reported questionnaire. Results: Correlation and regression analyses revealed that while job stress predicted lower quality of life, having problem-focused coping style and family support enhanced quality of life among child care teachers. Furthermore, results showed significant moderation effects of support from directors at child care centers on the relationship between job stress and quality of life among child care teachers. Conclusion/Implications: The findings suggest the important role of problem-focused coping styles and family support in enhancing quality of life. Moreover, support from directors at child care centers appeared to buffer the effects of job stress on quality of life among child care teachers. Results were discussed in terms of their implications for educational and counseling programs for child care teachers.

Objective: The purpose of this study is to investigate the effects of parents' perception of infant's use of digital devices on language development. Methods: For this study, a survey was conducted on 285 parents of 1-2year old infants attending childcare centers in Jeollanam-do. Results: First, the digital devices that infants were exposed to the most was the television, and their first exposure to digital devices was at 13~17 months. The most time spent using digital devices was 30 minutes and they most frequently used them at home. Second, parents perceived the educational value of digital devices as low. Third, language development was high when the initial use of digital devices for infants was late, when the daily use time of digital devices was less than 30 minutes, when digital devices were used with parents, and when parents always managed digital devices and usage time. Fourth, Parents' perception of the use of digital devices has a significant influence on their infants' language development. Conclusion/Implications: Language development due to the use of digital devices and parents' perception of the use of digital devices has a significant impact on infants language development.

Objective: The purpose of this study was to investigate the effect of mothers'play belief and their children's playtime on self-determination of young children. Methods: Participants of this study were 239 mothers of 6-year-old children attending childcare centers. An online self-report survey method was implemented to investigate whether mothers appreciate the contribution of play on their children's development, if mothers allow their children's playtime, and to examine the level of self-determination of their children. SPSS 22.0 was conducted for descriptive statistics and AMOS 21.0 was used for the path analysis to investigate the hypothetical relationship among variables. Results: Mothers' play support belief had a direct influence on their children's self-determination, while young children's playtime that was also affected by their mothers' play support belief had an indirect effect on their self-determination. Conclusion/Implications: The research shows that children's self-determination can be fostered by providing time to play when they can make decisions and demonstrate goal directed behaviors, and by providing an atmosphere that emphasizes the importance of playing in one's childhood.

Objective: The purpose of this study was to examine children's disclosure to parents in different domains of their daily activities. Methods: The participants were 340 children(100 kindergarteners, 120 3rd graders and 120 6th graders in elementary school) and their mothers in Seoul and Gangwon-do, Korea. The data was analyzed with one-way ANOVA, paired t-test, and MANOVA. Results: First, 3rd graders and 6th graders experienced more daily activities than kindergarteners in most domains. Second, 3rd graders disclosed more than kindergarteners and 6th graders in most domains. The response of mothers with 3rd graders was most similar to their children's response about children's disclosure to parents. Third, the reasons for nondisclosure of children were different according to domains. The reasons for nondisclosure of children that mothers perceived were different from those of their children, especially in the school(institute)-related domain. Conclusion/Implications: The results of this study indicated that the aspects of children's disclosure to parents were different according to domains of their daily activities based on developmental stages. Mothers perceived their children's disclosure differently compared to their children. The results suggest that it is necessary to approach children's disclosure to parents based on domains of daily activities and developmental stages.

Objective: Studies have revealed that parenting is a crucial factor for children's effortful control and externalizing behaviors, however, less is known about the underlying mechanism that may be moderated by maternal depression. Therefore, the present study is aimed to testify the mediating effect of children's effortful control and moderating effect of maternal depression in the association between parenting(i.e. limit setting, overprotective/permissive parenting) and children's externalizing behaviors. Methods: Three hundred and one mothers with 4 to 6 years old children reported their parenting behaviors, depression, their children's effortful control and externalizing behaviors. Data were analyzed using SPSS and Process Macro. Results: Results showed that children's effortful control mediated the association between parenting and children's externalizing behaviors and maternal depression moderated the association between parenting behaviors and children's effortful control as well as between parenting behaviors and children's externalizing behaviors. The moderated mediation effects were stronger among mothers with lower levels of depression. Conclusion/Implications: These findings could contribute to a better understanding of how and when maternal limit setting and overprotective/permissive parenting impact children's externalizing behaviors. It is suggested that future efforts to provide the parenting intervention take a target specific approach (e.g. considering mother's depression symptom), on order to maximize the effectiveness of program to ultimately facilitate children's positive adjustment.
