Objective: The purpose of this study is to examine the effect of childcare teachers' active motivation for choosing a profession on the quality of their interaction with infants and toddlers, and to investigate the moderating effect of their emotional dysregulation. Methods: The subjects of this study were childcare teachers working with infants and toddlers. A mobile survey was conducted and a total of 282 sets of results have been collected. Moderating effects have been explored with the use of PROCESS Macro (version 3.5) Model 1. Results: The main findings showed that childcare teachers' emotional dysregulation played a moderating role in the effect of childcare teachers' active motivation on the quality of interaction with infants and toddlers. Conclusion/Implications: The results of this study imply that the ability of childcare teachers working with infants and toddlers to regulate their emotions can simultaneously play a role as a protective factor as well as a risk factor for the quality of interaction. Also, it was revealed that is necessary to give pre-service teachers an opportunity to deliberate on their motivations for a childcare teacher position.

Objective: The purpose of this study is to examine the difference between teachers' traumatic experience and teachers' organizational commitment while considering individual differences of the childcare teachers and to investigate the effect of childcare teachers' traumatic experience on organizational commitment. Methods: This study used an online survey and collected data from 235 respondents. Then the data were analyzed by using a one-way ANOVA test, Scheffe post-hoc analysis, and hierarchical regression analysis. Results: First, this study found that there was a statistically significant difference between the traumatic experience of childcare teachers and teachers' organizational commitment depending on the age and career stage of the childcare teachers. Second, the childcare experience of childcare teachers showed a positive correlation with experience, and the traumatic experience showed a negative correlation with the organizational commitment. Third, childcare teachers' traumatic experience had a negative effect on normative and continuous immersion, respectively. Conclusion/Implications: This study contributes to the literature by recognizing the events that occurred in the process of childcare and identified the cause of the decrease in childcare teachers' motivation to work. It also suggests the need for continuous research on traumatic events that childcare teachers' experience during work in order to protect the rights and interests of childcare teachers.

Objective: The purpose of this study was to analyze the causal relationship between parenting knowledge, parenting stress, and parenting behavior of mothers with infants and to confirm the longitudinal mediating effect of parenting stress in the relationship between parenting knowledge and parenting behavior. Methods: This study used data collected through the Panel Study on Korean Children from 2008 to 2010 and the participants were 1,444 mothers with infants. The data were analyzed through technical statistics, correlations and multivariate potential growth models using SPSS 28.0 and AMOS 26.0. Results: Parenting knowledge and parenting stress of mothers gradually increased, and positive parenting behavior gradually decreased. Having a lot of parenting knowledge reduced mother's parenting stress. Mother's parenting stress reduced positive parenting behavior, and as parenting stress increased, positive parenting behavior decreased significantly. However, the relationship between parenting knowledge and parenting behavior was not significant. In addition, the mediating effect of parenting stress was confirmed in the relationship between parenting knowledge and parenting behavior of mothers. Conclusion/Implications: The results of this study suggest the need to reduce parenting stress and promote positive parenting behavior along with the systematization of parent education programs in order for mothers with infants to acquire parenting knowledge.

Objective: This study was conducted to examine the significant factors affecting media device addiction using the data mining technique for large-scale data from the Panel Study on Korean Children Survey (PSKC). The PSKC data of this study were gathered from the elementary school students in their 10th survey (1,286 3rd grade students). Methods: The SPSS 21.0 program was used for data mining decision tree analysis, and the results are as follows. Results: First, the most important predictor of media device addiction was planning-organization which was among the sub-factors of executive function. Second, as a result of the decision tree analysis, the children with the highest probability of addiction to media devices were ones that had difficulties in planning and organizing, had mothers with a permissive parenting attitude felt difficulties in controlling behavior, and were alone at home for more than two hours a day without any adult supervision. Conclusion/Implications: The results of this study can help guide the direction of future research related to children's addiction to media devices by exploring and analyzing factors that significantly affect children's addiction to media devices.
