Objectives: This study examined the changes in anxiety and depressive symptoms in the parents of Korean adults with autism spectrum disorder (ASD) after participating in the Korean version of the Program for the Education and Enrichment of Relational Skills for Young Adults (PEERS^® -YA-K). Methods: Forty-six parents were enrolled (mean age 54.7 years; 22 fathers and 24 mothers), of whom 27 participated in the PEERS^® - YA-K as social coaches. Participants completed self-report scales, including the Test of Young Adult Social Skills Knowledge (TYASSK), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and Symptom Check-List-90-R (SCL-90-R). The scales were administered three times: before and after the 16-week program and 4 months after the program ended. Differences between participant variables at pretreatment, post-treatment, and follow-up were analyzed using paired-sample t-tests. Results: Participants showed a significant improvement in their social skills knowledge (TYASSK) (p<0.01). There was a significant improvement in the BAI and BDI scores of parents with severe depressive and anxiety symptoms at the baseline (p<0.05). Paternal paranoia and maternal hostility results also significantly improved on the SCL-90-R. Conclusion: This study suggests that PEERS^® -YA-K can reduce parental anxiety and depressive symptoms. To the best of our knowledge, this is the first to compare the degree of depression and anxiety after PEERS^® -YA-K in parents of adults with ASD.

Purpose: This study examined the levels of and the associations between middle school students' attachments to parents, peers, and teachers, truancy, and school bullying. Methods: Data on middle school student were obtained from the Korea National Children and Youth Survey 2010 (N=2,968). The independent t-test and Kruskal-Wallis test were conducted to examine the differences in truancy and school bullying according to the characteristics of students. Multiple stepwise regression analysis was conducted to identify the factors influencing school bullying. Results: The magnitude of the correlation between truancy and bullying was r=.34 (p<.001). Two types of attachment(to parents and to teachers) were associated with school bullying, with the magnitude of r=-.06 (p=.003) and r=-.09 (p<.001), respectively. Truancy and all three types of attachment (to parents, peers, and teachers) predicted school bullying significantly (F=27.84, p<.001). Conclusion: In this study, truancy had more influence on bullying behavior than attachments to parents, teachers and peers among middle school students. These results suggest there is need to develop and provide programs to prevent or early intervene in truancy, an important predictor of school bullying, to reduce school bullying among middle school students.

Objective : The purpose of this study was to investigate effects of depression and anxiety on treatment response of social skills training in adolescents with autism spectrum disorders (ASD). Methods : A total of 107 teenagers that participated in the Program for the Education and Enrichment of Relational Skills (PEERS$^{(R)}$) between 2011 and 2015 were analyzed using linear regression. Outcome measures used were the Korean version of Social Responsiveness Scale (SRS), the Test of Adolescent Social Skills Knowledge-Revised (TASSK-R), and the Korean version of Autism Diagnostic Observation Schedule (K-ADOS). Depression and anxiety were assessed by the Korean version of Child Depression Inventory (CDI), the Korean version of State and Trait Anxiety Inventory for Children (STAIC), and the Korean version of Child Behavior Checklist (K-CBCL). Results : As a result, depressive symptoms measured by CDI (p<0.05) and anxiety symptoms measured by STAIC (p<0.05) had significant influence on score change of social interaction domain of ADOS. It remained significant even after the baseline score was adjusted as covariates (p<0.05). Conclusion : We observed that pre-treatment anxiety and depressive symptoms of teenagers had significant effects on the treatment outcome of PEERS$^{(R)}$, especially in terms of face-to-face social interaction.

To meet the increased demand of video-on-demand (VoD) services, peer-to-peer (P2P) mesh-based multiple video approaches have been recently proposed, where each peer is able to find a video segment interested without resort to the video server. However, they have not considered the constraint of the server's upload bandwidth and the fairness between upload and download amounts at each peer. In this paper, we propose a novel P2P VoD streaming system, named peer cache adaptation (PECAN) where each peer adjusts its cache capacity adaptively to meet the server's upload bandwidth constraint and achieve the fairness. For doing so, we first propose a new cache replacement algorithm that designs the number of caches for a segment to be proportional to its popularity. Second, we mathematically prove that if the cache capacity of a peer is proportional to its segment request rate, the fairness between upload and download amounts at each peer can be achieved. Third, we propose a method that determines each peer's cache capacity adaptively according to the constraint of the server's upload bandwidth. Against the proposed design objective, some selfish peers may not follow our protocol to increase their payoff. To detect such peers, we design a simple distributed reputation and monitoring system. Through simulations, we show that PECAN meets the server upload bandwidth constraint, and achieves the fairness well at each peer. We finally verify that the control overhead in PECAN caused by the search, reputation, and monitoring systems is very small, which is an important factor for real deployment.

MPEG-21 has identified the need fur Event Reporting in its vision for an interoperable multimedia framework. Event Reporting is required within the MPEG-21 multimedia framework in order to provide a standardized means for sharing information about Events amongst Peers and Users. Such Events relate to Digital Items and/or Peers that interact with them. Arising from an each Event, there is the opportunity to describe what occurred. However, there are a number of difficulties in providing an accurate report about an Event. Different observers of the Event may have vastly different perspectives, needs, and focuses. They may emphasize certain elements to the detriment of others, or they may describe an Event in a way that others may find confusing. In this paper, we design how to express Event Reporting message structure and system architecture in compliance with ISO/IEC 21000-15. And we implement the system for MPEG-21 Event Reporting service.

In this paper, we propose a FDR(False Data Reduction) strategy for P2P environment that reduces false data. The key idea of our strategy is that we use FDR algorithm to stop transmitting of false data and to delete that. If a user recognizes false data in downloaded-data and the user's peer requests the others to stop the transmission of the false data immediately. Also, the FDR algorithm notifies the other peers to prohibit spreading of the false data in the environment. All this procedure is possible to be executed in each peer without any lookup server. The FDR algorithm needs only a little data exchange among peers. Through simulation, we show that it is more effective to reduce the network traffic than the previous P2P strategy. We also show that the proposed strategy improves the performance of network compared to previous P2P strategy. As a result, The FDR strategy is decreased 9.78 ~ 16.84% of mean true data transmission time.
