The purpose of this study was to investigate young children's play preferences through observation at their classrooms and to examine the relationship between children's play preferences and their peer competence and peer acceptance. The subjects were 55 four-year-old children from a kindergarten in C city of Chungnam province. The data was analyzed by MANOVA, t-test, and Pearson's correlation. The results were as follows: first, boys and girls showed different play preferences except for language play and science play. Boys were better liked by same-sex peers while girls were better liked by other-sex peers. Second, there were significant correlations among certain play preferences. Block play preferences were negatively correlated with other play preferences. Third, some play preferences were significantly associated with some sub-dimensions of peer competence. Language play displayed a positive relationship to pro-social behavior, but art play showed a negative relationship to leadership. Finally, peer acceptance was positively correlated only with number/manipulation play preferences. Other-sex peer acceptance was positively correlated with number/manipulation play preferences and art play preferences but negatively with block play preferences.

This study examined short-term longitudinal reciprocal relationships between maternal parenting behavior and preschoolers' compliance/noncompliance, as well as stability in both maternal parenting behavior and preschoolers' compliance/noncompliance over time. The sample which was used for this study was taken from a two-wave (one year apart) longitudinal study of preschool-aged children and their mothers (N = 53 dyads). At both times, mothers and their children were invited to a laboratory and engaged in 25 minutes of play involving three episodes of mother-child interaction. Maternal parenting behavior and preschoolers' compliance/noncompliance during play were coded using the Dyadic Parent-Child Interaction Coding System-III (DPICS-III). Maternal codes included positive, neutral, and negative parenting behaviors and child codes were comprised of compliance and noncompliance. The results revealed that during the play session, maternal neutral and negative parenting behavior and preschoolers' compliance were stable over time. In addition, T1 maternal negative parenting behavior was significantly related to T2 child compliance/noncompliance. However, T1 child compliance/noncompliance were not significantly associated with T2 maternal parenting behavior. These findings suggest that during the preschool period, there are unidirectional effects from mothers to children.

The purpose of this study is to develop an evaluation model to measure the core competences of actual play workers by exploring what competences are necessary for them to provide quality play. Based on literature review, we selected five core competences : knowledge of play, program development, understanding play culture, creativity, and information sharing & applying. In order to achieve the research purpose end, a two-round Delphi survey was conducted on 10 play and education experts. The findings drew scholarly consensus on the competences of play workers to have and proposed basic data by developing competences evaluation model to measure them. Each of the key competences has three sub-conpetences, each of which included two behavior elements. Furthermore, this study presented future research directions so that play can be voluntarily planned and supported in a social and cultural context.

Interfaces, both grain boundaries and phase boundaries, play a very important role in the mechanical behavior of structural materials. The problemis particularly intense in composite materials where interfaces play a primary role in the meehanical response of the composites. This paper will concentrate on the approaches to perform nondestructive evaluation of the interfaces in a man nor in which some measure of the mechanical behavior of the interface can be established. Some of the possible approaches that may have potential for the nondestructive evaluation of interfaces are optical, electronic/ electrical, and acoustic approaches.

The study examines the play theory based internet rumor process by using simulating tools, Vensim, which offer a new theoretical basis from which to explore complex adaptive social system. Internet rumor is not a simple linear diffusion process, but a complex interaction behavior between the actors of production and diffusion. Rumor actors consist of two type of diffusion, which is rumor mongers and playful mongers. These two type of mongers make the internet rumor as collective system. Playful mongers play strategically to maximize playfulness. Internet rumor as play is consequence of collective framing constituted by dynamic interaction and playfulness. The networking space spreading internet rumor function as a playground which mobilize play rule, ignoring fact based framing. Rumor as paly, even though it turns out to be a false and loses the public attentions rumor sustains the game play function which makes the rumor without natural extinction. The study proves that playful mongers is a main actors in rumor play ground.

This study investigated the relationship between pretend play and comprehension of pretense by type of stipulated transformation among 2-and 4-year-olds children. Each child participated in pretend play with its mother for 10 minutes and in a stipulated task for comprehension of pretense. There was a significant difference in 2- and 4-year-olds in frequency and level of pretend play, and pretend play behavior was related to comprehension of pretense. Level of pretend play was positively related to comprehension of 'complexity' of stipulated transformations. This showed that there was significant relationship between development of pretend play and ability to comprehend pretense based on physical transformation.

The purpose of this study was to explore the characteristics of the children's rough-and-tumble play, and investigate the differences in rough-and-tumble play according to children's gender and social competence. The subjects were 80 five to six year-old children. The children's behaviors during the outdoor play were observed by a modified version based on the Rough-and-Tumble Play Categories(Humphreys & Smith, 1987). Children's social competence was measured by using the Scale for the Social Competence of Kindergarten(Doh, 1994). The data were analyzed by descriptive statistics, t-test, and ANCOVA. The results were as follows: Firstly, about 25.6% of outdoor play types was rough-and-tumble play behaviors. Specifically, children's rough-and-tumble play was more 'chasing' behaviors than 'mock-fighting' behaviors. Secondly, boys involved in rough-and-tumble play more often than girls did. In general, boys participated more frequently in various rough-and-tumble play categories, whereas girls involved only in chasing behavior more often. Finally, controlled by sex, children with higher social competence participated more frequently in rough-and-tumble play, which showed statistical significance. In conclusion, children's rough-and-tumble play behaviors were related to the gender and the social competence.

Google Play is one of the largest Android phone app markets and it contains both free and paid apps. It provides a variety of categories for every target user who has different needs and purposes. The customer's rate every product based on their experience of apps and based on the average rating the position of an app in these arch varies. Fraudulent behaviors emerge in those apps which incorporate search rank maltreatment and malware proliferation. To distinguish the fraudulent behavior, a novel framework is structured that finds and uses follows left behind by fraudsters, to identify both malware and applications exposed to the search rank fraud method. This strategy correlates survey exercises and remarkably joins identified review relations with semantic and behavioral signals produced from Google Play application information, to distinguish dubious applications. The proposed model accomplishes 90% precision in grouping gathered informational indexes of malware, fakes, and authentic apps. It finds many fraudulent applications that right now avoid Google Bouncers recognition technology. It also helped the discovery of fake reviews using the reviewer relationship amount of reviews which are forced as positive reviews for each reviewed Google play the android app.

Purpose: This study was to develop and evaluate a folk play program as a nursing intervention for the elderly with dementia. Method: First, a folk play program was developed through a careful study of literature review and field-work. Second, a nonequivalent control group pre-post test was designed. The subjects of the study were the elderly with dementia staying in nursing homes; 15 were in an experimental group adopting a folk play program developed through this study, 18 in the control group on a gymnastics and walking program which is generally used. The 40 min. intervention was conducted 5 times a week for 4 weeks. Result: The folk play program improved the cognition(t=6.12, p<.001) and ADL(t=2.92, p=.014) and diminished the frequency of problematic behaviors significantly(t=-6.39, p<.001). There was a significant difference of cognition, ADL, and problematic behaviors between the control and the experimental group before and after the experiment(t=3.38, p=.002; t=2.05, p=.046; t=-7.74, p<.001). Conclusion: Compared with the gymnastics and walking program, the folk play program proved to be much more effective in the elderly with dementia in improving their cognition and ADL, as well as in diminishing their problematic behaviors. Therefore, a folk play program should be appliedas an effective and practical Korean nursing intervention for the elderly with dementia.

This study examined whether sequential transition patterns of social play differed by children's social competence. The social competence of sixty 5-year-old children was rated by their teachers using the Social Competence Scale(NICHD Early Child Research Network, 1996). Children's social play was observed during free play and coded by criteria developed by Robinson et al(2003). Results showed differences in children's social play behaviors by social competence and differences in the transition patterns of children's social play level by social competence. Children with higher social competence showed a transition pattern moving toward cooperative-social interaction, whereas children with lower social competence showed a transition pattern moving backward to solitary or onlooker behavior.
