The purpose of the this study was to examine the relationship between mother-child interaction play assessment of children with Attention Deficit Hyperactivity Disorder(ADHD) and delinquency through observational method. The subjects were 30children(normal: 15, ADHD: 15) between 4-6 elementary school grade. Instruments used Parent-Child Interaction Assessment(P-CIPA), Inventory of Delinquency-Oriented Behavior and Korea Children Behavior Check List(K-CBCL). Results showed that following : 1) ADHD affect the delinquency-oriented behavior; 2) there were significant differences in mother-child interaction play assessment between normal children group and ADHD children group; and 3) there was a significant relationship between parent-child interaction play assessment and delinquency.

The purpose of this study is to investigate the learning achievement of students who has taken the play-based and activity-oriented programs in the class. These new science class programs and instrument to measure student learning achievement were developed for the "Constellation Favorite" lesson of 4th grade students and Those are verified by science education experts, teachers in serve. The subjects of this study consist of 121 students in four classes who were selected on the basis of midterm examination result before teaching treatment. They were divided into two categories with two classes per each category, one class for experimental group and the other class for control group. The experimental groups were given five classes including five play-based class programs. The control groups were given five conventional instruction-type classes. The students were given questionnaires to test their interest ratings. The results show about 17% increase of their learning achievement with (p<0.005) by independent sample T-test method and 40% increase of interest rating in play-based class sample compared to normal class sample. In conclusion, the play-based science class program is found to enhance the students' learning achievement and to interest the students more effectively.

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.

Objective : This paper is a report on the PLAY inSIde camp which connects sensory integration and play; the camp was designed for celebrating the KASI's 20th anniversary. Subjective : The camp was consisted of group play activity programs based on sensory integration for children aged 5~6 years with developmental disorder. The programs consisted of the Opening Program, Group Activity Program, Post Group Activity Program, and the Closing Activity Program. During the children's programs, their parents participated in parent education. The therapists participating in the camp planned and envisioned activity programs through pre-meetings and rehearsal sessions, where there were discussions among therapists and supporters. Conclusion : Through the camp, children experienced play activities involving sensory integration with other children, therapists shared their expertise in interaction with other therapists, and the KASI could share the accumulated resources with the society. After the events designed by the KASI, social participation through the occupation based on sensory integration could be facilitated and promoted in the future.

The objective of this research is to find out the relationship among resilience of young children, their interactive peer play, and mothers' overprotective parenting attitudes. The research was conducted for 455 children aged 3~5 and their mothers of day care centers in the cities of Kimje and Iksan. To measure resilience of young children, the rating scale for parents and teachers(Koo, 2010) adapting DECA(1999) was used. And the interactive peer play scale of Choi and Shin(2008) adapting PIPPS(1998) and the Parental Protectiveness of Do and Falbo(1999) was used. The results from this research are as follows. First, there is a generally significant positive correlation between resilience and interactive peer play of young children. Resilience of young children gets higher as interactive peer play of young children gets higher. Second, there is low negative correlation between resilience and mothers' overprotective parenting attitudes. Resilience of young children gets higher as mothers' overprotective parenting attitudes get low.

Users quite often experience volatile channel conditions which negatively influence multimedia transmission. HTTP adaptive streaming has emerged as a new promising technology where the video quality can be adjusted to variable network conditions. Nevertheless, the new technology does not remain without drawbacks. As it has been observed, multiple video players sharing the same network link have often problems with achieving good efficiency and stability of play-out due to a mutual interference and competition among video players. Our investigation indicates that there may be another cause for under-performance of the streamed video. In an emulated environment, we implemented three algorithms of adaptive video play-out based on bandwidth or buffer assessment. As we show, traffic generated by players employing the same or similar play-out strategies is positively correlated and synchronised (clustered), whereas traffic originated from different play-out strategies shows negative or no correlations. However, when some of the parameters of the play-out strategies are randomised, the correlation and synchronisation diminish what has a positive impact on the smoothness of the traffic and on the video quality perceived by end users. Our research shows that non-correlated traffic flows generated by play-out strategies improve efficiency and stability of streamed adaptive video.

In this paper, we use the interface, which many countries concentrates research of Brain - Computer Interface with the device and MyndPlay based on the IoT intelligent Arduino. Finally we will make the Brain - Computer Connection environment, the purpose of Brain - Computer Interface. Recognizes the EEG of a person who wearing the equipment, analyze, classify, and we did a research to design an intelligent thing to suit user's condition. In addition, we use the XBee, and Bluetooth to communicate to other devices, such as smart phone. In conclusion, this paper check users current status via brain waves, and it allows to control the power and other objects by using the EEG(Electroencephalography).

The purpose of this paper is to exhibit existing replacement models and to develop new replacement models for managing equipments in large organizations, private or public. Some of the models in this paper are well known and in use, and some are not. All these models are classified, depending on main factors which play key roles on the models. One group is the models in which the economic factor plays a key role, and the other is those in which both the economic factor and the effectiveness factor play key roles.
