This study investigated differences in toddlers' language development depending on their teachers' types of interaction during reading of picture books. A pilot study identified teachers' types of interaction as instructional, non-immediate, and passive. Fifteen teachers recruited from 10 child-care centers located in Seoul and their 90 2-year-old toddlers participated in this study. Teachers read two picture books to a small group of toddlers each week for eight weeks. Data on the toddlers' receptive and expressive language, vocabulary, reading behavior, and book handling were collected and compared by their teachers' interaction type before and after teachers' 8-week reading of picture books. Results showed that teachers using the non-immediate interaction type had the most positive effects on toddlers' language development.

The mechanism of interaction of four coumarin derivatives (CDS) with bovine serum albumin (BSA) was studied using spectrofluorometric technique. It was found that the coumarin ring common to all CDS makes major contribution to interaction. Binding affinities could be related to parachor values of CDS. Stem-Volmer plots indicated the presence of static component in the quenching mechanism. Results also showed that both tryptophan residues of protein are accessible to CDS. The high magnitude of rate constant of quenching indicated that the process of energy transfer occurs by intermolecular interaction forces and thus CDS binding site is in close proximity to tryptophan residues of BSA. Binding studies in the presence of the hydrophobic probe, 8-anilino-l-naphthalein-sulfonic acid showed that there is hydrophobic interaction between CDS and the probe and they do not share common sites in BSA. Thermodynamic parameters obtained from data at different temperatures showed that the binding of CDS to BSA involve hydrophobic bonds predominantly. The effects of various metal ions on the binding of CDS with BSA were also investigated.

The purpose of the this study was to examine the relationship between mother-child interaction play assessment of children with Attention Deficit Hyperactivity Disorder(ADHD) and delinquency through observational method. The subjects were 30children(normal: 15, ADHD: 15) between 4-6 elementary school grade. Instruments used Parent-Child Interaction Assessment(P-CIPA), Inventory of Delinquency-Oriented Behavior and Korea Children Behavior Check List(K-CBCL). Results showed that following : 1) ADHD affect the delinquency-oriented behavior; 2) there were significant differences in mother-child interaction play assessment between normal children group and ADHD children group; and 3) there was a significant relationship between parent-child interaction play assessment and delinquency.

Gene-environment interactions are important in pathogenesis of suicide or suicidal behavior. Twin and adoption studies and family studies show that genetic factors play a critical role in suicide or suicidal behavior. Given the strong association between serotonergic neurotransmission and suicide, recent molecular genetic studies have focused on polymorphisms of serotonin genes, especially on serotonin transporter and tryptophan hydroxylase genes. Some studies have revealed a significant interaction between s allele of the serotonin transporter gene and the risk of suicide attempt associated with childhood trauma. In addition, the polymorphism of brain-derived neurotrophic factor gene also may influence the effect of childhood trauma in relation to the risk of attempting suicide. Future studies should explore genetic and environmental factors in suicide or suicidal behavior and examine for gene and environment interaction.

This study was to find out children's Negotiation Levels(NLs) according to their age and gender. The subjects for this study were 143 children of 7, 9, 12 years. Two children dyads participated in the experimental play situation with Rokenbok Electronic Toy Systems. The NLs in children's interactive dialogue & actions were scored with Stone, Robinson & Taylor(1980)'s 'Negotiation of Task Completion Coding Manual'. They were coded into Level 0(no interaction), Level l(one way interaction), Level 2(reciprocally interaction), Level 3(mutual or cooperative interaction). The results were as follows; 1) 12-year-old children negotiated with higher level than 7-and 9-year old children 2) Boys' NLs average were higher than girls'. These results imply that 1) the fluctuation of NLs in childhood, especially around 10 years, should be interpreted carefully, 2) various measuring kits for negotiation should be developed considering children's characteristics, such as age, gender etc.

The purpose of this study was to investigate whether attachment to primary caregivers and family interaction affect rural children's social competence through self-regulation ability. To achieve this, a survey was conducted with 345 students aged 11-13 attending elementary schools in a rural area of Gyeongsang Province. Data were analyzed using descriptive statistics, Pearson correlation analysis, and path analysis using the AMOS 23.0 program. The main result was that rural children's self-regulation had an indirect effect on attachment with primary caregivers and family interaction through social competence. The findings of this study will contribute to designing a variety of programs that can promote the positive development of social competence among rural children.

Objective: The purpose of this study was to investigate trajectories of child peer interaction and to compare the causal effects of their predictors, including child individual variables (i.e., gender, language ability, and cognitive ability) and teacher variables (i.e., teacher efficacy and teacher-child interaction). Methods: The participants of this study were 263 children and their teachers from the forth to sixth waves of longitudinal data from the Korean Children and Youth Panel Survey by the Korea Institute of Child Care and Education. The data was analyzed using Pearson's correlation and latent growth modeling. Results and Conclusion: The findings of this study are as follows: First, there was a linear decrease in child negative peer interaction over the course of 3 years, and significant individual differences were found in the trajectories (intercept and slope). Second, the predictors had significant casual effects on the trajectories of child negative peer interaction. The trajectories of child negative peer interaction involving girls, higher cognitive ability, and greater teacher-child interaction showed lower degree of intercept and a quicker decrease. Finally, the implications of findings are discussed.
