The attachment representation of 40 36- to 52-month-old upper-middle class children was analyzed in relation to their attachment security and mother-child interaction behaviors. Instruments were the Attachment Story Completion Task(Bretherton, Ridgeway, & Cassidy, 1990), the Attachment Q-set, and the Vocabulary test of the K-WIPPSI. Mother-child interaction behaviors were observed at home during semi-structured problem-solving situations. The Attachment Story Completion Task classified Korean preshoolers from these upper-middle class families as securely attached to their mothers. Girls' representation of their attachment relationship was more secure than boys. Preschoolers' attachment representation was significantly related to vocabulary ability. Attachment security correlated positively with preschool children's attachment representation. Mother-child interaction behaviors related significantly to preschool children's attachment representation.

The purpose of this study was to investigate the effects of the home literacy environment, mother's literacy belief and parenting efficacy in terms of the interaction which occurs during reading picture books between mothers and preschoolers. Questionnaires from 378 5-year-olds' mothers in Seoul and Kyunggi province were analysed. The findings from the validated structural equation model constructed with these variables were as follows. First, the home literacy environment, the mother's literacy beliefs and the mother's general parenting efficacy affected the quantity, and the quality of interaction whilst reading books with preschoolers. Second, the mother's efficacy in education and communication had a direct impact on the quantity of the interaction during reading books through the mediation of the home literacy environment, and had an indirect effect on the quality of the interaction whilst reading books, respectively. Third, the mother's efficacy in communication directly accounted for the quality of the interaction which occurs whilst reading books with children.

This study investigated the effectiveness of teachers inquiry-discovery verbal interaction which was compared with expository-directive verbal interaction. Two teachers from two different kindergarten groups were trained and observed during conversation and science corner activities. Sixty children were observed during science corner activities and tested with a scientific achievement instrument. Teacher's inquiry-discovery verbal interaction had a more positive effect on children's scientific attitudes than teacher's expository-directive verbal interaction. Teacher's inquiry-discovery verbal interaction had a more positive effect on children's scientific achievement than teacher's expository-directive verbal interaction. Children's scientific attitudes and children's scientific achievement had a positive correlation.

The mechanism of interaction of cyanocobalamin (CB) with bovine serum albumin (BSA) has been investigated by spectrofluorometric and circular dichroism methods. Association constant for the CB-BSA system showed that the interaction is non-covalent in nature. Binding studies in the presence of an hydrophobic probe, 8-anilino-l-naphthalene sulphonic acid, sodium salt (ANS) showed that there is hydrophobic interaction between CB and ANS and they do not share common sites in BSA. Stern-Volmer analysis of fluorescence quenching data showed that the fraction of fluorophore (protein) accessible to the quencher (CB) was close to unity indicating thereby that both tryptophan residues of BSA are involved in drug-protein interaction. The rate constant for quenching, greater than $10^{10}$ $M^{-1}$ $s^{-1}$, indicated that the drug binding site is in close proximity to tryptophan residue of BSA. Thermodynamic parameters obtained from data at different temperatures showed that the binding of CB to BSA involves hydrophobic bonds predominantly. Significant increase in concentration of free drug was observed for CB in presence of paracetamol. Circular dichroism studies revealed the change in helicity of BSA due to binding of CB to BSA.

This study developed and validated a 'Parent-child Lexical Interaction Scale for Preschoolers (PLIS-P)'. First, we developed the preliminary scale with 7 factors after reviewing previous literature related to vocabulary and literacy instruction for young children and reflected on feedback from child studies experts and mothers with young children. Subsequently, to validate the scale, the online survey was conducted on mothers with 5-to 6-year-old children who live in Seoul, Gyeonggi, Incheon, Gyeongsang, Chungcheong, Jeolla, Gangwon, and Jeju. Responses from 309 mothers were used to conduct exploratory and confirmatory factor analysis and correlation analysis. The results were as follows. First, the result of exploratory analysis showed that the model with 7 factors was satisfactory: (1) vocabulary exposure, (2) word elaboration, (3) scaffolding, (4) play activity, (5) conventional instruction, (6) word type awareness instruction, (7) word morphology instruction. Second, confirmatory factor analysis confirmed the good fit of the model. Third, the concurrent validity was confirmed by correlation analysis using EC-HOME. Last, the internal consistency reliability of each factor of PLIS-P was also confirmed. This study developed both a theoretical framework of parent-child lexical interaction and a Parent-child Lexical Interaction Scale for Preschoolers. This scale can be used by parents, practitioners, and researchers to acquire knowledge about interaction related to words between Korean parents and young children.

This study investigated parenting knowledge, interactions between mother and infant, and relationship between mother's parenting knowledge and mother-infant interaction by mothers' demographic variables. Subjects were 311 mothers. Instruments were the Knowledge of Child Development Inventory (Larsen & Juhasz, 1986) and the Assessment Profile for Early Childhood programs (Abbott-Shim & Sibely, 1987). Data were analyzed by t-test and ANOVA. Results showed (1) differences about parenting knowledge by mothers' employment status, age and education level, (2) differences in mother-infant interaction by mothers' age and education level, (3) parenting knowledge about physical development correlated positively with positive interaction, linguistic modeling, and sensitive response knowledge about linguistic and cognitive development had a large effect on positive mother-infant interaction and linguistic modeling.
