Objective: This study examines the relationships among four-year-olds' counting skills, their use of number words, and their mothers' use of number words during mother-child free play. Specifically, we assess whether children's use of number words mediates the relationship between their counting skills and their mothers' use of number words during play. Methods: Forty-two 4-year-old children and their mothers were asked to play freely with a given set of toys at their home for 10 minutes. Children also completed a counting skill test. Frequencies of number word use were calculated for mothers and children from transcriptions of the free play. Results: Children's counting skills, the frequency of their number word use, and their mothers' frequency of number word use were positively correlated with each other. Additionally, the frequency of children's number-word use completely mediated the relationship between their counting skills and their mothers' frequency of number-word use. Conclusion/Implications: The results suggest that children's use of number language may play a crucial role in the provision of number-related language input by parents, based on their children's math skills. Practical implications of the findings are discussed.

The main objective of this study is to investigate the perception, recognition and response of innovative/ self-initiated play and its correlation to play space and play environment understood by children in their middle childhood years. Play, play theory, and the acceptance of play have an important role in child development. In recent years, play and the importance of innovative/ self-initiated play have been associated with a number of important societal issues. The impact of play and/or lack of play during the developmental stages of childhood directly influence a child's ability to mature and adapt into society. In order to investigate the overall perceptions of play and play space among the average child in their middle childhood, a questionnaire survey was distributed and analyzed using SSPS 15.0. This survey was conducted within the site specific context of South Korea. Interestingly enough, the differences in the responses can be organized into three main categories: age, gender and housing type. In result different directions for further study and research for future play spaces and play environments that support innovated/ self-initiated play have been suggested.

Remorins, a family of plant-specific proteins containing a variable N-terminal region and conserved C-terminal domain, play a role in various biotic and abiotic stresses, including host-microbe interactions. However, their functions remain to be completely elucidated, especially for the Arabidopsis thaliana remorin group 4 (AtREM4). To elucidate the role of remorins in Arabidopsis, we first showed that AtREM4s have typical molecular characteristics of the remorins, such as induction by various types of biotic and abiotic stresses, localization in plasma membrane and homo- and hetero-oligomeric interaction. Next, we showed that their loss-of-function mutants displayed reduced susceptibility to geminiviruses, Beet Curly Top Virus and Beet Severe Curly Top Virus, while overexpressors enhanced susceptibility. Moreover, we found that they interacted with SnRK1, which phosphorylated AtREM4.1, and were degraded by the 26S proteasome pathway. These results suggest that AtREM4s may be involved in the SnRK1-mediated signaling pathway and play a role as positive regulators of the cell cycle during geminivirus infection.

The B cell translocation gene 1 (BTG1) and BTG2 play a key role in a wide range of cellular activities including proliferation, apoptosis, and cell growth via modulating a variety of central biological steps such as transcription, post-transcriptional, and translation. BTG1 and BTG2 have been identified by genomic profiling of B-cell leukemia and diverse lymphoma types where both genes are commonly mutated, implying that they serve as tumor suppressors. Furthermore, a low expression level of BTG1 or BTG2 in solid tumors is frequently associated with malignant progression and poor treatment outcomes. As physiological aspects, BTG1 and BTG2 have been discovered to play a critical function in regulating quiescence in hematopoietic lineage such as Hematopoietic stem cells (HSCs) and naive and memory T cells, highlighting their novel role in maintaining the quiescent state. Taken together, emerging evidence from the recent studies suggests that BTG1 and BTG2 play a central anti-proliferative role in various tissues and cells, indicating their potential as targets for innovative therapeutics.

This research suggests science inquiry play of analogy as a teaming method to help the students in concrete operational stage to develop scientific thinking skills and to understand abstract science conceptions. The research focuses on/considers the characteristics and merits of the science inquiry plays, and the learning method by analogical reasoning. This learning through the science inquiry play of analogy can be considered as a meta-model for scientific thinking skill. The learning has the following processes: 1) Students analogize the abstract science conceptions and facts into play-type activities including the concrete contents such as students themselves, their physical-sensory motions, concrete objects, play methods, and play rules. 2) Students as analogized objects play a role physically and sensuously according to the methods and rules analogized in the play. 3) Students find out the concrete contents included in the science inquiry play of analogy, draw the results, and deduce the new conceptions from the results by reflective thinking and analogical reasoning.

The two major theoretical frameworks that have informed research on symbolic play and cognitive development were reviewed. Piaget and Vygotsky had different views of the role of symbolic play in children's development. For Piaget, play is primarily an assimilative activity; that is, in play, children modify reality to fit their existent cognitive schema and desires. In his view, play does not facilitate development, but it is used to consolidate existent concepts. For Vygotsky, play is a precursor to symbolization and is a leading factor in development. Particularly the lack of a sociocultural dimension in Piaget's theory brought about the influence of Vygotsky, for whom this dimension is central. However, the research yielded so far has not fully investigated the wider sociocultural elements that define and inform the play context. This article concludes by suggesting an approach to children's play that is directed by a proper estimation of the interaction between its cognitive, emotional, and sociocultural dimensions.

The purpose of this study was to firstly, investigate the relationship between infants' communicative gestures, play and maternal responsiveness and secondly, to examine the role of maternal responsiveness in the associations between infants' communicative gestures and play. The subjects comprised 42 infants (21 boys and 21 girls) and their mothers. The infants' communicative gestures, the infants' play and maternal responsiveness were observed during free play sessions lasting 20 minutes. The results are as follows. Mothers of girls showed higher levels of responsiveness than the mothers of boys. In addition, here were positive correlations between infants' communicative gestures, play and maternal responsiveness. Maternal responsiveness was observed to moderate the effects of infants' communicative gestures on the infants' average level of play. These results indicate that it is important for caregivers to interpret infants' communicative intentions appropriately and respond promptly and adequately in play situations.
