Rhabdomyoma has been reported to be the most common type of cardiac tumors in fetuses and children, and multiple cardiac rhabdomyomas almost certainly signify the association with tuberous sclerosis. We report here on a case of Tetralogy of Fallot (ToF) that was associated with multiple rhabdomyomas and tuberous sclerosis. A two-year-old boy, who had undergone systemic-pulmonary shunt during the neonatal period, received total correction of his ToF after the complete regression of the cardiac tumor. The postoperative course was uneventful, and he has been follow-up for 2 months. The boy is currently in an excellent condition.

Objective: The purpose of this study was two-fold: first to explore the effects of mother-child attachment and effortful control at age 1 on preschoolers' school readiness at age 6, and second, to determine the mediating effect of a child's effortful control on the relationship between mother-child attachment at age 1 in relation to school readiness at age 6. Methods: Participants in this study were 205 five-year-old toddlers(106 boys, 99 girls) recruited for the Korea Child Panel Study. Mother-child attachment was assessed using the Attachment Q-sort(Waters, 1989). Preschooler's effortful control was measured by the Early Childhood Behavior Questionnaire: ECBQ(Putnam, Gartstein & Rothbart, 2006). Preschooler's school readness was measured by the School Readiness Scale Murphey & Burns, 2002). Data were analyzed using descriptive statistics, correlations, and the structural equation modeling analysis. Results: First, mother-child attachment at age 1 effected school readiness at age 6. Effortful control at age 1 effected school readiness at age 6. Second, effortful control at age 1 mediated the effect of mother-child attachment at age 1 in relation to school readiness at age 6. Conclusion/Implications: Mother-child attachment at age 1 affects school readiness at age 6, and toddlers' effortful control at age 1 mediates the relationship between mother-child attachment in relation to school readiness at age 6.

Objective: The purpose of this study was to investigate the effects of fathers' playfulness and play participation on preschoolers' peer competence. Methods: The participants in the study were 325 preschoolers and their fathers. The survey method was used to investigate fathers' playfulness, fathers' average level of play participation as well as playtime with their children and preschoolers' peer competence. In order to analyze the data, one-way ANOVA and regression analysis were utilized. Results: The results showed that fathers' playfulness and play participation were different according to the fathers' weekly working hours. It was found that the higher the cheerfulness of the sub-factors of fathers' playfulness was, the higher the sociability of sub-factors of preschoolers' peer competence was. The amount of fathers' play time with children as well as the average level of play participation, which is the qualitative aspect of fathers' play participation, was found to affect preschoolers' peer competence and the three sub-factors of competence. Conclusion/Implications: The findings implied that fathers' active play participation with children is important and that there is a need to improve working conditions in order for fathers to have time to play with their children.

Objective: The objective of this study is to investigate the tendency of research in relation to childcare curriculum for 0 to 2 year-olds, and then to analyze and understand the results of precedent research about the status of the operation of Childcare Curriculum. Methods: The analytic data utilized in this research contains a total of 45 research results about childcare curriculum for 0 to 2 year-olds. Results: First, the research methods were focused on quantitative research. Regarding research topics, the status of the operation of Childcare Curriculum, and contents and programs of Childcare Curriculum received high attention. Second, while, childcare teachers showed an awareness of the Childcare Curriculum, they made few efforts to investigate and understand it in depth. It was reported that a lack of multiple support systems would serve as an obstacle to the operation of Childcare Curriculum. Conclusion/Implications: There is a need for childcare centers, academic circles and the government to pay an even greater deal of attention to the childcare curriculum for 0 to 2 year-olds. In addition, structural and policy support is required, such as revitalizing case-based teacher training, lowering the ratio of teachers to children, and improving working conditions for infant teachers.

Objective: This study aims to explore the intra-action between infants and picture book reading in a daycare setting, aiming to gain new insight into infants' reading experiences. Methods: The participants in the study were 12 infants from the Bluebird Class (1-year-old) at A Daycare Center. To comprehensively examine the context and flow of the infants' experiences, participant observation was conducted during free play sessions, held three to five times a week, in the morning, from December 19, 2022, to February 17, 2023. Results: Firstly, infants engaged in the intra-action with symbols such as text, images, lines, colors, and latent narratives in picture books, spontaneously encountering meaning-making. Secondly, they explored the potential of materials such as their own bodies, the dacare classroom environment, and blocks, creating narratives through the process of 'becoming'. Thirdly, infants generated shared experiences by creating interactions within their relationships with others in the daycare class. Conclusion/Implications: This study highlights a shift in perspective, recognizing infants as active readers who construct their own understanding. Additionally, it underscores the significance of cultivating an infant-centered environment and the meaningful role of teachers in supporting and facilitating such an environment.
