The purpose of this study was to investigate the perception and need for the revised child care practicum (January, 2017) in Korea. The participants were in three groups: 32 directors, 143 child care teachers and 130 pre-service teachers. Questionnaire were used ot collect the data and t-test, x-test and ANOVA were done for analysis. All three groups responded positively for the revised edition (extending the period of practicum from 4 weeks to 6 weeks). And perceived the extending the period is necessary for the quality of child care centers. Directors with the higher level of education perceived the revision clearly than others. Most of teachers perceived the change through teacher retraining program. All groups pointed out for the implementing the revised edition successfully, supporting and cooperative system is in need for three groups.

The purpose of this study was to examine practice of strategies childcare teachers use in order to promote peer interaction among young children and difficulties in implementing strategies by using mixed methodology. The participants of current study were 155 inservice childcare teachers and they completed SIPPY questionnaire. To investigate strategy practice with difficulties, 44 teachers participated in theme writing and 3 teachers were interviewed. SIPPY data were analyzed by SPSS 20.0 and theme writing and interview transcripts were coded by qualitative analysis procedure. Results are as follows; First, teachers in this study use more environmental and naturalistic activity strategies than intensive strategies. Depending on educational experience and education level, there was a statistically significant difference. Second, participants reported various natural activity strategies that they use in the classroom such as compliments, modeling, suggestion, cooperative activity plan. Based on the analysis of qualitative data, four categories of difficulties were presented such as environmental component, disconnection with families, child individual characteristics, and teacher component. Implications were discussed in terms of teacher education and teacher driven professional development program.

Ecological predictors of imaginative playfulness were researched to test relationships among preschoolers' individual characteristics, socioeconomic status, their visual media use, and their imaginative playfulness. Data were collected from 202 primary caregivers and head teachers in childcare centers in Michigan, U. S. A. Use of visual media was coded by the program categorization of Anderson et al. (2001) and the Television and Movie Violence Rating Scale (Huesmann et al. 2003). Imaginative playfulness was rated by the adapted Playfulness Scale (Barnett 1990). Results of hierarchical regression showed that child characteristics of age and gender predictors contributed to their imaginative playfulness. On the other hand, children's visual media use and socioeconomic status of their families did not predict their imaginative playfulness.

Objective: This study is to examine the associations between fathers' values and future expectations on children and their self-evaluated equivalence to their spouses in child rearing practices. Methods: The data were from 997 fathers with young children who participated in the Panel Study of Korean Children (2013). The associations between variables were analyzed with frequency, correlations and hierarchical analysis using SPSS 20 Program. Results: Fathers with emotional values on children or future expectations focused on their children's happiness and altruism are more willing to share child raring practices with their partners. In contrast, fathers with expectation focused on future financial success of their children are less willing to share parenting with their partners. Conclusion/Implications: Fathers' values and future expectations for their children are meaningful predictors of shared parenting in married couples with young children. However, the directions of associations differ based on which types of values and future exportations fathers have regarding their children.

Objective: The purpose of this study is to investigate the moderating role of Ego-Resilience between Peer Attachment and Mobile Phone Dependency in late adolescence. Methods: The participants were 2056 third year high school adolescents (1,041 boys and 1,015 girls) from the Korea Youth Panel Study (KYPS), a national representative of Korean Children and adolescence. Hierarchical Regression was used for data analysis. Results: First, the correlation between peer attachment, ego-resilience and mobile phone dependency were all significant. Second, ego-resilience takes the role of moderator for mobile phone dependency. In detail, ego-resilience relieves the mobile phone dependency caused by 'peer relationships' or 'conflict in peer relationships. Conclusion/Implications: Ego-resilience was found to control the relationship between peer attachment and mobile phone dependency. Therefore, in order to lower the dependence of mobile phones in adolescents with low peer attachment, a program that can enhance ego-resilience is needed.

Subjects were 88 two-year-old-toddlers(25-36 months of age) and 32 teachers in 13 childcare centers; they were randomly assigned to experimental or control groups. The researcher observed teacher-toddler interaction in the picturebook reading situation. Analysis of patterns of teachers' verbal behavior and coding of toddlers' verbal and nonverbal behaviors were based on Senechal, et al.(1995) and Whitehurst, et al.(1988), respectively. In comparison with the control group, toddlers of the experimental group showed significant differences in verbal behavior; they acquired nouns occurring in the picturebooks and more expressive and comprehensive language. After training intervention, teachers of the experimental group showed changes in quality and quantity of verbal behavior.

Objective: The purpose of this study is to analyze the structural relations between infant teachers' career, efficacy, sensitivity, and the development of their professionalism. Methods: Data were collected from 320 infant teachers working at day care centers in Gyeonggi-do and Seoul. The collected data were applied to SPSS 22.0 program. With the data, correlation analysis and structural equation model analysis were conducted. Results: Firstly, infant teachers' career didn't influence the development of their professionalism directly, but indirectly affected their efficacy and sensitivity. Secondly, the variables that directly affected the development of their professionalism were teacher efficacy and sensitivity. Thirdly, teacher efficacy and sensitivity had full mediation between their career and the development of professionalism. Conclusion/Implications: Infant teachers' career affected the development of their professionalism through teacher efficacy and sensitivity. Based on the result, a plan for developing infant teachers' professionalism was proposed, and suggestions of follow-up research were discussed.

The study aimed to determine the effects of Early Childhood STEP on parenting stress and child's behavior. The study subjects were 29 Korean mothers and their child. The researcher translated the Parent's guide of the Early Childhood STEP into Korean, along with the video tapes for parents. The experimental group was educated with the Early Childhood STEP program (lecture, reading educational material, discussion, watching video). To determine the pre- and post-test differences of parenting stress and infant behavior, t-test was used. The results are presented below. First, Early Childhood STEP exhibited a decreasing effect on the parenting stress of mothers. Second, STEP exhibited a decreasing effect on the infant behavior, particularly the behaviors in the areas of incapability, revenge, and power reactions.

Support vector quantile regression (SVQR) can be obtained by applying support vector machine with a check function instead of an e-insensitive loss function into the quantile regression, which still requires to solve a quadratic program (QP) problem which is time and memory expensive. In this paper we propose an SVQR whose objective function is composed of an asymmetric quadratic loss function. The proposed method overcomes the weak point of the SVQR with the check function. We use the iterative procedure to solve the objective problem. Furthermore, we introduce the generalized cross validation function to select the hyper-parameters which affect the performance of SVQR. Experimental results are then presented, which illustrate the performance of proposed SVQR.

Teacher's practical knowledge is potentially relevant to the teaching practice in his/her classroom. The research explored early childhood teachers' practical knowledge of 'curriculum' via conceptual metaphors. The participants (N=348) completed a prompt, "Curriculum is like A because B" and then the metaphors were analyzed according to the procedure proposed by Moser (2000). The analysis found that 8 themes (i.e. 'educational basis', 'learning opportunity', 'educational material', 'difficulty', 'change', 'pre-determination', 'discordance', and 'reconstruction') were the underlying conceptions signified in those metaphors. The implications regarding early childhood teachers' practical knowledge were discussed on the perspective of post-modern curriculum. Moreover, it recommended the practical knowledge based approach for early childhood teacher education, and transformation of current policy for program evaluation relevant to curriculum conceptualization.
