The dissociation constants(K) of m-chloroanilinium ion in water-ethanol mixture, where the volume percentage of water is 89.5%, were evaluated by UV-spectroscopic method at $20{\sim}50^{\circ}C$, up to 1500 bars with changing ionic strength from 0.04 to 0.10 mol $kg^{-1}$ by use of acetate buffer. K values enhance with increasing ionic strength and temperature, but decrease with elevating pressure. From K values, we obtained the partial molar volume change and some other thermodynamic parameters. From the values of enthalpy, entropy and isoequilibrium temperature (649 K), we concluded that the dissociation of m-chloroanilinium ion mentioned above is controlled by enthalpy.

In present study, using 1572 low-income families and 266 Head Start teachers from Family and Child Experiences Survey (FACES) in the U.S., we examined the effects of mothers' reading and the characteristics of interaction between teacher-child interaction on 4-and 5-year-olds' cognitive development represented by their verbal and numerical abilities. Frequencies of mothers' reading at home consistently predicted higher scores of children's Peabody Picture Vocabulary Test and Woodcock Johnson Applied Problems. Teachers' sensitivity and permissiveness in their interactions with children in classroom were positively related to children's verbal abilities and teachers' sensitivity predicted better numerical abilities of children after controlling for mothers' reading and the characteristics of family and teacher. The findings shed light on the contributions of teacher behaviors and familial factors to children's cognitive development calling for attention to the need for parent education on cognitively stimulating family environments and continuing education for early childhood teachers focusing on quality interactions with young children.

Objective: This study analyzed the compliance situation of class rules for 3-year olds in the Wisdom class at Sarang kindergarten. Methods: Research participants were composed of 17 young children and two teachers in the wisdom class for 3-year-olds and data collection and analysis were conducted by participant observation using the qualitative method. Results: Research results were as follows. The compliance situation of class rules included compliance, violation, and among compliance and violation. First, compliance was divided into compliance with assistance and self compliance. Compliance with assistance is for young children to follow the rules under the guidance, help, and instructions of teachers. Self compliance is for children to understand and follow the rules themselves. Second, Between compliance and violation is conflict of the rules created by different standards of class rules. Third, depending on who found the violation, violation was classified into teacher discovery, peer discovery, and acquiescence. The teacher discovery led to teacher guidance and teacher acquiescence, The peer discovery led to peer notification, peer resistance, peer punishment, and peer acquiescence. Conclusion/Implications: By looking at the compliance situation of class rules for three-year-olds, the educational implications of how to guide class rules were obtained for children.

The effects of conflicted teacher-child relation on conflicted or passive peer interaction and a moderation effect of mothers' interpersonal relation satisfaction on the associations were assessed. Children from 2- to 6-year-olds (184 girls, 185 boys) mostly from middle socioeconomic-status urban community in Korea and their teachers and mothers participated. Conflicted teacher-child relation predicted conflicted peer interaction but not passive peer interaction. Children, whose relationship with teachers were conflicted, engaged in conflicted play with peers more often than children who were in less conflicted relationship with the teachers. Teachers who were in conflicted relationship with the children, perceived the children having conflicted interaction with peers more often, if mothers of the children were less satisfying in relationship with significant others, especially boys. Children, whose mothers are in less satisfying interpersonal relation with others, were more passive in peer interaction than children whose mothers are in more satisfying interpersonal relationship.
