The purpose of this study was to investigate the effects of mothers' parental intelligence on children's peer play interaction and peer acceptance. The participants were 197 fiveyear- old children and their mothers of six kindergartens and child care centers in Seoul and Gyeonggi province. The Penn Interactive Peer Play Scale(Choi & Shin, 2008), the Peer Rating Scale(Asher et al., 1979), and the Parental Intelligence Scale(Hyon, 2004) were used as measurements. The results of this study were as follows. Firstly, the higher scores in mothers' parental intelligence of encouragement, enhancement, rational authoritativeness, acceptance, control, and avoiding rejection roles, the more the children's positive behaviors were exhibited during the peer play. Secondly, children whose mothers provided higher levels in parental intelligence of empathy, encouragement, rational authoritativeness and enhancement roles were rated as displaying higher levels of children's peer acceptance. On the other hand, children whose mothers expressed higher parental intelligence level of the rejection role tended to have lower levels of peer acceptance.

The purpose of this case study is to analyze the characteristics of social interaction according to gender-grouping in the application of LTTS program. For this study, mixed-gender group A (one boy and three girls or one girl and three boys), mixed-gender group B (two boys and two girls) and same-gender group (4 boys or 4 girls) were formed. Social interactions during group discussions were audio-/video-taped. Social interactions between one boy and one girl in each group were analyzed. The type of social interactions were classified as cognitive and affective interactions. The boy and the girl in the same gender group tended to make suggestion actively, but sometimes they ordered peers to participate or prevented peers from participating. On the other hand, they didn't tend to make suggestion about problem-solving in mixed-gender group A, but made suggestion against peer's opinion using appropriate reasons. The frequency of affective interactions in the mixed gender group B were higher.

This study investigated the effects of preschool teachers' ethical awareness and teaching flow on the teacher-preschooler interaction based on the participation of 345 preschool teachers in Chungcheongnam-do and Gyeonggi-do. The collected data were analyzed by correlation analysis and hierarchical regression analysis. The results of the study were as follows: First, both teachers' ethical awareness and teaching flow were strongly correlated with the teacher-preschooler interaction, and the correlation between sub-variables was also significant. Second, analysis of the relative strength of teachers' ethical awareness and teaching flow in the explanation of the teacher-preschooler interaction revealed that intrinsic motivation as a sub-variable among teaching flow was the most prominent predictor of the teacher-preschooler interaction, followed by ethics for preschoolers among teachers' ethical awareness as well as specific plans among teaching flow. The findings of this study suggest future directions for teacher education based on newly identified factors affecting teacher-preschooler interactions, desirable teacher-preschooler interactions, and implications for improving childcare quality.

This paper examines an augmented technology acceptance model, which includes perceived interaction as a mediator in the relationships between the technology acceptance model (perceived ease of use, perceived usefulness) and student satisfaction in online classes, and its impact on student satisfaction. Data has been collected from 842 undergraduate students in online universities. The data is analyzed by using factor analysis and structural equation modeling techniques. The results demonstrate that perceived ease of use, perceived usefulness, and perceived interaction serve as predictors for student satisfaction in online classes. Perceived usefulness has a positive relationship with perceived interaction while perceived ease of use has no effect on interaction.

암을 억제시키는 기능을 하는 단백질로 잘 알려진 p53은, 주로 종양세포에서 과도하게 발현되는 단백질인 HDM2와 복합체를 형성하여 비활성화되고 항암기능을 상실하게 됩니다. 때문에 종양세포에서의 p53-HDM2의 상호작용을 억제하기 위해 현재까지 많은 연구가 진행되어왔으며, 다양한 p53-HDM2 억제제가 개발된 바 있습니다. 최근 연구들에 따르면, HDM2와 결합친화도를 높이고 소수성 작용(hydrophobic interaction)에 기여하여 보다 안정한 구조를 만드는 탄화수소체인(staple)을 연결시킨 펩타이드 설계에 대한 관심이 높아지고 있는 추세입니다. 이에, 본 연구에서는 분자동역학 모의실험을 통해서 얻은 탄화수소체인-p53과 비탄화수소체인-p53 및 각각의 HDM2와 결합한 복합체를 기반으로 EDISON의 용매화 자유에너지(Solvation Free Energy) 프로그램을 이용하여 탄화수소체인의 특징 및 역할을 구조적인 측면과 열역학적인 측면으로 분석하여 비교하고자 합니다. 우리 연구에서 비탄화수소체인-p53의 구조는 분자동역학 시뮬레이션을 수행하는 동안 나선구조형태로 풀려 HDM2와 결합 유도 시에 주요결합 아미노산 잔기가 올바른 결합부위와 상호작용하지 못한 결과를 확인한 반면, 탄화수소체인이 형성된 구조는 시뮬레이션 동안에도 펩타이드의 나선구조를 유지시켜 HDM2와 주요 결합을 형성하는 아미노산 잔기들을 올바른 방향으로 배치시켜 HDM2와의 결합친화도를 높였습니다. 이 연구 결과는 탄화수소체인이 펩타이드의 나선성을 유지시키고, HDM2와의 상호작용을 통한 구조적인 안정성 유도 및 용매화 자유에너지에 큰 기여를 통해 p53-HDM2상호작용 억제제에서 긍정적인 역할을 할 가능성을 보여줍니다.

Exploring microRNA (miRNA) and mRNA regulatory interactions may give new insights into diverse biological phenomena. Recently, miRNAs have been discovered as important regulators that play a major role in various cellular processes. Therefore, it is essential to identify functional interactions between miRNAs and mRNAs for understanding the context- dependent activities of miRNAs in complex biological systems. While elucidating complex miRNA-mRNA interactions has been studied with experimental and computational approaches, it is still difficult to infer miRNA-mRNA regulatory modules. Here we present a novel method, termed layered hypernetworks (LHNs), for identifying functional miRNA-mRNA interactions from heterogeneous expression data. In experiments, we apply the LHN model to miRNA and mRNA expression profiles on multiple cancers. The proposed method identifies cancer-specific miRNA-mRNA interactions. We show the biological significance of the discovered miRNA- mRNA interactions.

The purpose of this study was to examine the relations between the quality of teacher-child relationship, child temperament, and teacher-child interaction. The subjects were 51 3-4 years old children who were attending a preschool in Seoul and their mothers. The mothers of the young children rated child temperament and the head teachers of the children evaluated the quality of teacher-child relationship. The frequency of teacher-child interactions in the classroom was collected through observation during self-selected activities in the classrooms. Observational data included frequency of teacher-initiated interactions and number of child-initiated interactions. The results showed that boys were more likely to have conflictual relationships with teachers and girls were likely to have close relationships with teachers. And lower levels of effortful control were associated with teacher-child conflict. More child-initiated interactions were related to the conflict relationships with teachers. Results suggest that child characteristics and teacher-child interactions contribute to children's relationships with teachers.

In this study, the influences of magnetization reversal and magnetic interaction on the coercivity of Sr-ferrite particles with different sizes were investigated through various magnetic measurements. The shape of the initial magnetization curve and the magnetic field dependence of the coercive force indicate that the magnetization reversal changes from domain nucleation to wall pinning as the particle size decreases. On the other hand, the Henkel plot, interaction field factor and ${\Delta}M(H)$ obtained from the DCD and IRM curves show that the strength of the dipolar interaction is increased with increasing the particle size. Therefore, it can be concluded that coercivity is closely related to magnetic interaction as well as magnetization reversal mechanism.

This study analyzed the effect of perceived interactivity in health information websites on users. First, this study analyzed the effect of users' individual characteristics on the perceived interactivity. As a result, hypochondriasis had a negative relationship with perceived interactivity, and health literacy had a positive relationship with it. On the other hand, although the perceived interactivity had a positive effect on users' attitudes toward health information websites and expected outcomes, it did not have an effect on continuous usage intention. However, their attitudes and perceived outcomes had a positive influence on continuous usage intention and at the same time mediated the perceived interactivity. Eventually, the perceived interactivity had an effect on continuous usage intention of health information websites by the medium of other positively related variables.
