The purpose of this study was to analyse 3, 4, 5-year-old children's private speech according to their age and task characteristics (structured task vs. unstructured task). In order to achieve the goal, the main effect of age, characteristic of tasks and interaction effect were considered among age and characteristic of tasks on preschool children's private speech. The subjects were each 30 3, 4, 5-year-olds from preschool in Busan, South Korea. The structured task was puzzle task and the unstructured task was drawing task from TCT-DP. The data was analyzed by repeated measurement two way ANOVA: 3(age) ${\times}$ 2((characteristic of task). As a result, firstly, total private speech of 4-year-old was higher than 3-year-old, 5-year-old in both tasks, and total private speech of 5-year-old was higher than 3-year-old in both tasks. Secondly, the task-irrelevant private speech was not affected by main effect of age and characteristic of task and interaction effect between age and characteristic of task. Thirdly, the task-relevant private speech was received both main effects and interaction effects between age and characteristic of task. Finally, the external manifestation of inner speech were not received effect of age but received effect of characteristic of task, and received interaction effect between age and characteristic of task. The results of this study imply that characteristic of task is an important factor inducing children's private speech.

This study examines the mediation effect of teacher-child interactions in the process of the impact of teacher's teaching-efficacy on childhood education institutions and classroom environment on peer-play interactions. We used data from 970 children aged between 49 and 55 months and 970 homeroom teachers from the fifth Korean Child Panel (2012) of the Korea Institute of Child Care and Education. The model fitness was excellent after data were statistically analyzed with model of structure to testify the relationship and effect among teaching efficacy, classroom environment, teacher-child interactions, and peer-play interactions. First, the analysis also showed that the teacher's teaching efficacy did not influence peer-play interactions directly, but gave an indirect effect on the peer-play interactions with the mediation of the teacher-child interactions. Second, the classroom environment directly and indirectly influenced the peer-play interactions with the mediation of the teacher-child interactions. Third, the variable of teacher-child interactions was fully effective as a mediating variable in the process of the teaching efficacy and classroom environment influence on teacher-child interactions. Teaching efficacy and classroom environment influenced the peer-play interactions through the mediation of the teacher-child interactions. The significance of mediation effect of the teacher-child interactions was verified through a bootstrapping method.

The effect of anionic polyelectrolytes, poly(styrenesulfonate) (PSS) and poly(vinylsulfonate) (PVS), on the charge transfer complexing between indole derivatives and methyl viologen($MV^{++}$) cation was investigated. The results were compared with effect of NaCl and an anionic surfactant, sodium dodecylsulfate (SDS). Both PSS and PVS enhanced the complex formation of neutral species (indole and indole acetate at low pH), zwitter ionic tryptophan, and positively charged tryptamine and tryptophan at low pH with $MV^{++}$. This result was attributed to the contribution of hydrophobic interaction, in addition to electrostatic interaction. The enhancing effect of PSS was much higher than that of PVS reflecting the higher hydrophobicity of PSS. The interaction between indole acetate anion and $MV^{++}$ was greatly reduced by addition of PVS and PSS. The higher charge density of PVS was appeared as greater reducing effect indicating the importance of electrostatic force in this case. In all cases, the effect of polyelectrolytes showed maxima, and further addition of PVS and PSS decreased the effect. This behavior was explained in terms of distribution of indole derivatives and $MV^{++}$ in domain of polyanions. The complex formation constants and molar absorptivities of complexes were determined, and the values were compared with those in water and SDS solutions.

The principal objective of this study was to assess the effects of food involvement moderating the relationship between food choice motives, including health concerns, weight control and ethical concern, and fruit consumption. A total of 290 questionnaires were completed. Moderated regression analysis was utilized to assess the relationships among variables. The results of the study showed that the results of data analysis also indicated good model fit. The direct effects of health concerns on fruit consumption were statistically significant in Models 1 and 2. However, the direct effects of ethical concern on fruit consumption were statistically significant in Model 3. As had been expected, the interaction of ethical concerns and food involvement exerted a significant effect on fruit consumption in Model 3. However, the interaction of health concern and food involvement, as well as weight control and food involvement exerted no significant effects on fruit consumption. Moreover, ethical concerns about fruit consumption exerted a significant negative effect at the low level and a positive effect at the high level of food involvement, except in cases in which the level of food involvement was medium. The results of this study revealed that fruit marketers should attach importance to the interaction effect of food involvement in order to better understand the elements of market demand and customer loyalty.

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.

The theoretical framework of the interaction fields for multiple scales based on field theory is applied to one-dimensional problem mimicking dislocation substructure sensitive intra-granular inhomogeneity evolution under fatigue of Cu-added steels. Three distinct scale levels corresponding respectively to the orders of (A)dislocation substructures, (B)grain size and (C)grain aggregates are set-up based on FE-RKPM (reproducing kernel particle method) based interpolated strain distribution to obtain the incompatibility term in the interaction field. Comparisons between analytical conditions with and without the interaction, and that among different cell size in the scale A are simulated. The effect of interaction field on the B-scale field evolution is extensively examined. Finer and larger fluctuation is demonstrated to be obtained by taking account of the field interactions. Finer cell size exhibits larger field fluctuation whereas the coarse cell size yields negligible interaction effects.

The most important features of linear soil-foundation-structure interaction are reviewed, using stochastic modeling and considering kinematic interaction, inertial interaction, and structural distortion as three separate stages of the dynamic response to the free-field motion. The way in which each of the three dynamic stages modifies the spectral density of the motion is studied, with the emphasis being on interpretation of these results, rather than on the development of new analysis techniques. Structural distortion and inertial interaction analysis are shown to be precisely modeled as linear filtering operations. Kinematic interaction, though, is more complicated, even though it has a filter-like effect on the frequency content of the motion.
