Objective: In this study, a department accreditation system was introduced as a specific way to improve the professionalism of childcare teachers, and evaluation indicators for department accreditation and the implementation system were derived to find a practical direction. Methods: According to the purpose of this study, related laws and websites were reviewed. In addition, in order to investigate opinions on the composition and implementation system of qualification indicators, a meeting was conducted with professors of the department of childcare teacher education and other qualification experts. Results: In order to introduce a department accreditation system for childcare teacher education, it is necessary to specify the relevant laws, and that the operation of an organization affiliated with a public institution is appropriate for the practical implementation of the system. In addition, an evaluation index plan composed of three indicators of educational conditions, curriculum, and performance areas was derived. Conclusion/Implications: In this study, a practical preparation plan, such as evaluation indicators and an implementation system, was presented for the introduction of a department accreditation childcare teacher education system. It is expected that this study will contribute to the successful establishment of the accreditation system of childcare teacher education.

Objective: The purpose of this study was to analyze the effect of a director's support for coding education perceived by childcare teachers on the participation of teachers in the learning community and the intention to implement coding education. Methods: The participants of this study were 312 early childhood teachers working at daycare centers in Seoul, Gyeong-gi, and In-cheon area. The data were collected through the survey questionnaires and analyzed using a structural model to explore the relationship between variables. Results: Verifying the mediating effect of infant teacher participation in the learning community between a director's support and infant teacher's intention to implement coding education positively mediates the director's support and infant teacher's intention to implement coding education. In particular, it was discovered that the intention to participate in coding-related learning communities had the greatest impact on infant teachers' intentions to implement coding education based on total effectiveness. Conclusion/Implications: The above analysis results suggest that in order to enhance the intention of infant teachers to implement coding education, it is necessary to support the learning community related to coding education and encourage participation from infant teachers.

Objective: This study aimed to examine the sequential mediating effects of children's perceived maternal acceptance and peer acceptance in the relationship between maternal warmth and first grade children's school adjustment. Methods: Participants in this study were 979 seven-year-old children(498 boys, 481 girls) recruited for the Korea Child Panel Study. Data were analyzed by analyzing descriptive statistics, correlations, and significance of serial mediation pathways using SPSS 18.0 and PROCESS Macro 3.4. Results: Maternal warmth at age five effected perception of maternal acceptance at age six. Perceived maternal acceptance at age six effected perceived peer acceptance at age six. Perceived peer acceptance at age six effected school adjustment at age seven. Lastly, perceived maternal acceptance and peer acceptance at age six had a serial mediation effect between maternal warmth at age five and school adjustment at age seven. Conclusion/Implications: Perceived social acceptance during preschool years should be emphasized in order to promote school adjustment for first grade children. Parent education for promoting better parent child relationships should be considered and teachers should encourage peer play interaction to help children perceive acceptance from their peers.

Objective: The purpose of this study was to examine the impact of children's age and their fathers' childrearing involvement on the social morality of young children. Methods: The data were gathered from parents who had 3-5 year old children enrolled in daycare centers and from their daycare teachers. The parents answered questions about their children's socio-demographic background and the father's childrearing involvement. And the teachers rated children's social morality. The data from a total of 245 questionnaires were analyzed by SPSS 25.0. Results: First, there was a statistically significant difference between young children's morality score and convention score. Young children's morality scores were higher than their convention scores. Second, children's age was a significant influential factor on both their moral and conventional social morality. Third, father's care-discipline had the only impact on children's conventional social morality. That is, children's social morality was higher when their fathers gave them more care and guidance. Forth, an interaction effect between children's age and father's development-support on children's conventional social morality was found. Conclusion/Implications: The results from this study suggest that a differentiated approach is needed according to the types of childrearing involvement of fathers in order to improve children's social morality.

Objective: This study aimed to develop a longitudinal predictive model that identifies first-grade children who are at risk for ADHD and to investigate the factors that predict the probability of belonging to the at-risk group for ADHD by using machine learning. Methods: The data of 1,445 first-grade children from the 1st, 3rd, 6th, 7th, and 8th waves of the Korean Children's Panel were analyzed. The output factors were the at-risk and non-risk group for ADHD divided by the CBCL DSM-ADHD scale. Prenatal as well as developmental factors during infancy and early childhood were used as input factors. Results: The model that best classifies the at-risk and the non-risk group for ADHD was the LASSO model. The input factors which increased the probability of being in the at-risk group for ADHD were temperament of negative emotionality, communication abilities, gross motor skills, social competences, and academic readiness. Conclusion/Implications: The outcomes indicate that children who showed specific risk indicators during infancy and early childhood are likely to be classified as being at risk for ADHD when entering elementary schools. The results may enable parents and clinicians to identify children with ADHD early by observing early signs and thus provide interventions as early as possible.

Objective: This study aimed to explore the experience and meaning of pre-service early childhood teachers who practiced health promoting activities for themselves. Methods: Research participants were 115 pre-service early childhood teachers enrolled in the health education for children course at one college in G region. The reports of activity records of their eight-week long health promotion activities were collected as qualitative data followed by content analysis being implemented. Results: First, the experience of the health promoting activities the participants took part in was categorized into 'Early phase of experience: A mix of worries and anticipation, and success and failure', 'Mid phase of experience: Being motivated by physical changes and records', and 'Late phase of experience: Continuous execution through habituation.' Second, the meaning of health promotion activities the participants took part in was categorized into 'A great opportunity for introspection', 'A meaningful start of college life', and 'A valuable chance to consider desirable roles of a teacher for early childhood health education.' Conclusion/Implications: The results of this study suggest that pre-service early childhood teachers should pay close attention to their health management, and that contents that emphasize the importance of teachers' health should be included in health education.
