This research investigated young children's social interaction and task performance in dyadic collaboration. The independent variables were gender and social skill level(high/low groups). Twenty-four pairs each 4-year-old boys and 4-year-old girls(total 96 subjects) worked at a block reconstruction. Two researchers judged degree of dyadic collaboration. Data were processed by 2 way ANOVA and Pearson's product correlation. While no main effect for gender was found, the effect for social skill level(high/low groups)was significant for social interaction. There was positive correlation between social interaction and task performance.

This study investigated relationships among infant development, teacher's sensitivity, home literacy environment, and infant-teacher interaction in the child care setting. Verbal and behavioral interactions between 30 2-year-old infant-teacher pairs were video-recorded during free play activities; teachers' sensitivity was observed by trained observers; infant development was assessed by teachers; data on the early home literacy environment were gathered through maternal self-reported questionnaires. Data were analyzed by descriptive statistics, t-tests, and correlation analyses. Results indicated that boys showed more naming; girls showed more physical contact with teachers. Infants high in overall developmental level showed more behavioral interaction with teachers. Teacher's sensitivity correlated positively with behavioral imitating and negatively with questioning and nodding. Verbal interaction in the home correlated positively with nodding.

This study was designed to assess the developmental sequence of children's understanding of social interaction and to test the effects of support conditions and behavioral domains on the understanding of social interaction. The subjects were one hundred 4- to 8-year-old children. The method was a doll play situation, composed of three different support conditions. Scalogram analysis was used to test the developmental sequence, and ANOVA and paired t-test were used to test the significance of differences in stages. The results of this study evidenced a sequential pattern in the 4- to 8-year-old children's understanding of social interaction. There were also significant differences between stages in the understanding of social interaction according to support conditions and behavioral domains. Higher levels of support produced higher stages of understanding and the understanding of positive social interactions were higher than those of negative social interactions at ages 4 and 5.

Poly(A) polymerase (PAP) play an essential role for maturation of mRNA by adding the adenylate residues at the 3' end. PAP functions are regulated through protein-protein interaction at its C-terminal region. In this study, cyclophilin A (CypA), a member of the peptidyl-prolyl cis-trans isomerase family, was identified as a partner protein interacting with the C-terminal region PAP. The interaction between PAP and CypA was inhibited by the immunosuppressive drug cyclosporine A. Deletion analysis revealed that the N-terminal 56 residues of CypA are sufficient for the interaction with PAP. Interestingly, we observed that PAP and CypA colocalize in the nucleus during SDF-1-induced chemotaxis, implying that CypA could be involved in the regulation of polyadenylation by PAP in the chemotactic cells.

The purpose of this study is to investigate the moderating effects of language abilities associated with between emotionality, attention deficit hyperactivity disorder (ADHD) and peer play interactions. Two hundred fifty-two participants were 3 year olds, with 136 boys and 116 girls. They were recruited from day care centers and preschools in Gyunggi province and Incheon city. Peer play interaction was assessed by the Penn Interactive Peer Play Scale (PIPPS). Emotionality was measured by Child Behavior Questionnaire (CBQ). ADHD was assessed by teacher ratings of ADHD syndrome. Language abilities were measured by Korean Wechsler Preschool and Primary Scale of Intelligence (K-WPPSI). Teachers completed questionnaires to assess peer play interactions, emotionality, ADHD. The results revealed that language abilities moderated relationships between emotionality and play in isolation. The magnitude of associations between emotionality and play in isolation was greater for high levels of language abilities. Moreover, there were moderating effects of language abilities associated between ADHD and play disruptions. Although ADHD was significantly associated with play disruptions, the association was stronger at the higher levels than the low levels of language abilities. It can be deduced that language abilities of 3 year old children affects the protection factor between emotionality and peer play isolation; whilst, it affects the risk factor on peer play disruptions and ADHD propensity.

This study investigated talk about mental states in pretend play, to whom mental states were attributed, and function of mental-state terms. Also, frequency of mental-state terms of pretend versus non-pretend turns was examined. Thirty 4 year old preschoolers, each paired with a self-chosen peer, were observed and videotaped during a 20-minute play session. The observations presented the following conclusions: Knowing and pretending were the most frequently expressed. Children attributed a large proportion of mental state to themselves. The mental-state terms were used to refer his or another's thoughts and beliefs, to direct interaction, and to attract the other child's attention. Mental-state talk occurred within pretend more often than within non-pretend turns.

The purpose of this study was to analyze the effects of toddler's temperament and toddler-teacher relationship on their peer interaction, focusing on gender differences. A total of 221 toddlers(122 boys and 99 girls) attending 16 child care centers in South Korea participated in this study. Each toddler was observed during a free-play period in the classroom over 4 sessions of 5 minutes, so a total of 20 minutes was measured. Two observers scored recorded observation scenes with two peer interaction criteria, including interaction initiation and interaction participation level. The main results of this study are as follows: First, there was a signigicant gender difference in peer interaction and toddler's temperament and toddler-teacher relationship. Second, the factor of toddler-teacher relationship significantly predicted the boys' peer interaction, while for the girls, the significant predictor was intentional control of temperamental factors. Further, implications for different approaches according to the gender difference of the affecting factor on toddlers' peer interaction have been discussed.

The purpose of this study is to analyze manifestation examples and effects of group creativity in mathematical modeling and to discuss teaching and learning methods for group creativity. The following two points were examined from the theoretical background. First, we examined the possibility of group activity in mathematical modeling. Second, we examined the meaning and characteristics of group creativity. Six students in the second grade of high school participated in this study in two groups of three each. Mathematical modeling task was "What are your own strategies to prevent or cope with blackouts?". Unit of analysis was the observed types of interaction at each stage of mathematical modeling. Especially, it was confirmed that group creativity can be developed through repetitive occurrences of mutually complementary, conflict-based, metacognitive interactions. The conclusion is as follows. First, examples of mutually complementary interaction, conflict-based interaction, and metacognitive interaction were observed in the real-world inquiry and the factor-finding stage, the simplification stage, and the mathematical model derivation stage, respectively. And the positive effect of group creativity on mathematical modeling were confirmed. Second, example of non interaction was observed, and it was confirmed that there were limitations on students' interaction object and interaction participation, and teacher's failure on appropriate intervention. Third, as teaching learning methods for group creativity, we proposed students' role play and teachers' questioning in the direction of promoting interaction.

This study examines the father involvement during the infancy period. In order to explore the influence of the father's characteristics, the infant's characteristics and the contextual sources of stress and support on reports of father-infant interaction and paternal responsibility 500 fathers are studied. Results show that fathers in this sample are not regularly involved in the caretaking and the play tasks. The caretaking tasks are most significantly associated with fathers' emotional reaction while indirectly with the first baby, the difficult baby, and the marital satisfaction. The play tasks differ somewhat by their work hours and the marital satisfaction.
