다자간 분산형 협업 시스템인 Access Grid(AG)는 IP 멀티캐스트 네트워크상에서 여러 사용자들 간에 영상, 음성 및 다양한 데이터의 공유를 통해 상호 의사소통이 가능한 공동 작업환경을 제공하기 위해 개발되었다. 멀티캐스트를 사용함으로써 AG는 대역폭 효율적으로 다수 사용자 사이의 의사소통 환경을 제공하고 있다. 그러나 IP 멀티캐스트의 설정 및 관리상 복잡성으로 인해 이를 지원하지 않는 네트워크가 다수 존재한다. 이는 AG를 이용한 협업 서비스를 이용하는 데에 큰 장애물이 되고 있다, 본 논문에서는 이러한 멀티캐스트 연결성 문제에 대한 해결책으로 응용 계층의 멀티캐스트 터널링 프로토콜인 UMTP (UDP multicast tunneling protocol) 를 확장한 멀티캐스트 연결성 솔루션인 AG Connector를 제안한다.

BioPlace 시스템은 유전체 관련 연구자들의 효과적인 정보교환과 연구 활동을 지원하기 위한 웹기반 협업지원 시스템이다. 현재 BioPlace 시스템은 정보를 교환하는 방법이 대부분 비동기적 이어서 실제 공동작업의 과정에서 발생할 수 있는 여러 가지 전달사항이나 수시로 변하는 정보를 실시간으로 전달할 수 있는 방법을 제공하고 있지 않다. Jabber 메시징 시스템은 XML 기반의 개방형 메시징 시스템으로서 실시간 의사소통을 지원하기 위한 다양한 기능과 타 메시징 시스템과의 연동을 제공하고 있어서 능률적인 메시징 서비스의 개발을 지원한다. 따라서, BioPlace 협업지원 시스템에서 Jabber 메시징 서비스를 제공함으로써 이러한 문제를 해결할 수 있다. 본 논문에서는 BioPlace 협업지원 시스템에서 실시간 의사소통 수단으로 사용될 수 있도록 Jabber 실시간 메시징 시스템을 확장하여 BioPlace 메신저 시스템을 설계하고, 실제 구동 가능한 서버와 클라이언트 시스템을 개발하였다.

The purpose of this study is to research the reason of higher tendencies toward game addiction in the group of adolescents with highly educated parents than the group of adolescents with non-highly educated parents. The results show that the variables affecting adolescents' game addiction in the group of adolescents with highly educated parents are very different with those in the group of adolescents with non-highly educated parents. In the group of adolescents with highly educated parents, most of variables related to family function and communication types are not significantly affecting game addiction, while they are affecting in the group of adolescents with non-highly educated parents. This indicates that highly educated families might have particular family system related to stratification culture.

The purpose of this study was to examine the relationship between failure mindset of the mother and adolescent, along with the mediating effects of mother's happiness and mother-adolescents (first and second-year middle school students in Seoul) open communication. For this study, self-reported data of 270 mother-adolescent dyads were analyzed using SPSS and Process macro Model 6. The results revealed that the mother's failure mindset directly predicted their adolescent's failure mindset. The mediating effect of the mother-adolescent open communication was significant, but the mediating effect of the mother's happiness was not significant. However, the mediation effect of the mother's failure mindset on the adolescent's failure mindset through mother's happiness and mother-adolescent open communication was significant. These results suggest that "failure-is-enhancing" mindset of mothers improve their positive affect and parenting skills, which contributes to developing adolescent's belief system about failure. Putting the results together, this study is significant in that it identified the intergenerational relationship of the failure mindset. Besides, the study results serve as a foundation for intervening on the adolescent's failure mindset by verifying the developmental mechanism of the failure mindset.

This study examined the effects of STEAM program on preservice science teachers' communication competency and further explored their experiences of and reflection on STEAM program. The study design is one group pretest-posttest with mixed methodology using both quantitative and qualitative data. The STEAM program consists of three stages: introduction of STEAM, participation in STEAM activities, and reflection on the STEAM program. The preservice science teachers improved their communication competency after the STEAM program (p < .01). The preservice science teachers represented statistically higher scores on the three subscales of communication competency: Interpretation ability, self-presenting ability, and understanding others' viewpoints. In addition, the preservice science teachers reflected on their STEAM experiences. During the first stage of 'Presentation of the Problem Situation,' the preservice science teachers mentioned that they roused their curiosity due to everyday experience-related, social issues or present issues. In the stage of 'Creative Design,' the preservice science teachers mentioned that they selected the final idea through mutual consent of the members, the practical possibility of everyday life, the previous experience-based decisions, or persuasive power. Further, about 87.5% of preservice science teachers mentioned that they were fully engaged in the 'Emotional Learning' stages due to the application of integrated thinking, everyday related issues, and communication among group members. About 85% of the preservice science teachers mentioned that they could challenge new problems in future situations.

Objectives：One of the most common developmental problems is communication disorder in which a child appears normal in every way but who has failed to begin speaking or speaks very little. A few studies have examined the temperamental characteristics of children with communication disorders. This study was to investigate the temperamental characteristics of Korean children with communication disorders. Methods：The parents of 20 Korean children with communication disorders and the parents of 50 normal control children, the age of both groups ranges from 3 to 7, completed Korean version of Parental Temperamental Questionnaire developed by Thomas and Chess. Children with a pervasive developmental disorder, mental retardation, or speech-motor or sensory deficit were excluded. The scores of each temperamental scale of two groups and the diagnostic clusters of two groups were compared. Results：The children with communication disorders were characterized by lower mood scores and higher intensity of reaction scores than normal controls. The two groups showed no significant correlation in terms of the temperamental diagnostic clusters. Conclusion：This findings suggest the existence of a distinct temperamental profile of the children with communication disorders. Early detection of the profile may be of great value for parents in understanding the developmental characteristics of the children with communication disorders and in providing appropriate parenting approaches.

The purpose of this study is to verify the effect of SNS addiction on cyber-bullying among adolescents, considering the adjustment effect of friendship on this relationship. This study involved 811 middle/high school students with a gender distribution of 391 males and 420 females. According to the analysis, the higher the level of SNS addiction, the higher the level of cyber-bullying. A hierarchical regression analysis was conducted to verify the moderating effect of friendship. The result shows that better peer communication and reliance lowers the impact of cyber-bullying from SNS addiction. Based on research results suggesting the popularization of proactive pre-diagnosis programs to solve SNS addiction, practical intervention plans and the limitations of research on SNS addiction and cyber-bullying in youth are suggested.

The advance of information technology has changed the business environment, and the business process between the trading partners has been evolved with these changes. However, the business process between trading partners requires human interface for interchanging information or making a decision even though they collaborate each other or are coupled tightly, and this interrupts seamless business processes between them. To overcome this limitations, a new concept of self-integration has been emerged. The self-integration means a true integration among enterprise applications without human interface, and it might be the future direction of integrations. In this study, we introduced the concept of self-integration environment and business process model for supply chain planning. And, we analyzed the negotiation processes and classified the negotiation patterns for integrated supply chain planning in self-integration environment, and then we proposed a generic business process model for negotiation of extended and integrated supply chain planning by integrating the suggested negotiation pattern with business scenarios.
