In this paper, we propose Teloemedicine system on CBM(Computer Based Multimedia) based collaborative multimedia which supports special medicine and collaborative medicine with DB, face-to-face dffedt.This system is an application developed by SDK (Software Development Kit) of DooRae(Distributed Objected Oriented Multimedia Application Crafting Environment for Collaborative)framework.And this system is devel-Oriented Multimedia Applecation Crafting Environment for Collaborative) framework, And this system is devel-oped on windows 95 and windows NT.The scenario of this system is limited within only hospital(LAN), but it is possibloe to support many applications development in various nerwork(MAN, PSYN, WAN)on DooRae.This system has a smoth interaction by video and audio, multiple session, multiple participation, application sharing, toolbox including ICON and whiteboard.Also this system supports realo or non-real type without con-straint of the and space.

Existing multipath routing mechanism has much overhead to maintain the state of nodes on the multipath route and does not guarantees completely disjoint multipath construction from source to destination. In this paper, we propose an Explicit Disjoint Multipath (EDM) routing algorithm to enhance energy efficiency through removing the flooding mechanism for route discovery process, minimizing the number of nodes participating in route update and balancing the traffic load for entire network. EDM constructs logical pipelines which can create disjoint multipaths in logical way. Then it physically performs anchor node based geographic routing along the logical pipeline in order to build multipath to the destination. EDM can provide the distribution effect of traffic load over the network, help to balance the energy consumption and therefore extend the network lifetime.

PECOLE (Peer-to-Peer Collaborative Environment) is a P2P-based multimedia distributed collaborative environment supporting a collaborative workspace which is composed of a variety of collaborative applications such as multi-chat, video conferencing, screen sharing and etc. Unfortunately, due to the PECOLE's simple group management, it is impossible to perform collaboration activities while joining multiple groups. In this paper, we present the design and implementation of PECOLE+ which is an extension of PECOLE. PECOLE+ resolves the drawback of PECOLE by providing the Group Management Service and the Workspace Management Service. The Group Management Service provides functionalities such as creating groups, joining multiple groups, and searching groups, and etc. The Workspace Management Service provides each group with an associated workspace, supporting the execution of collaborative applications over the workspace. In addition, any collaborative applications with the provided plug-in interfaces can be executed over the workspace as a PECOLE+ collaborative application.

The present study intends to understand how multimodality can be implemented in a content course curriculum and how students perceive multimodal tasks. Twenty-eight students majoring in English were engaged in a digital storytelling assignment as a part of the content curriculum. Findings from the questionnaire and reflective essays that investigated students perceptions of digital storytelling showed that students felt that the assignment helped them engage in the task and felt motivated. In comparison to traditional writing tasks, students perceived digital storytelling to be more engaging and motivating, but felt that the assignment required more mental effort and caused more anxiety. By supporting students to explore technology and implement multimodal aspects in the learning process, digital storytelling can encourage engagement and autonomous learning to create meaningful works that are purposeful and enjoyable.

Co-creation is an important approach to innovation that uses internal and external sources for value creation. This study identified the effects of intrinsic motivation, extrinsic motivation, and the moderating effects of activation factors using multiple regression and moderated multiple regression. To this end, 181 usable questionnaires were collected and analyzed. The result of analysis showed that intrinsic motivation had the significant meaning and the moderating effects of activation factors on the relationship between extrinsic motivation and co-creation participation exist. Companies may use this result to activate the co-creation participation of the customer. The future study analyzed by survey responses in multiple layers will improve the generalization of the study.

This study was to find out relations among sports values of participants in sport for all, satisfaction of participation and intention to adhere to exercise. Objects of study were participants in sport for all and data had been collected by convenience sampling method. Among 250 copies of data, 233 copies had been used for final analysis. Collected data had been analyzed with frequency analysis, correlation analysis, multiple regression analysis by using of SPSS 21.0. The results from those processes are as below. First, value of personality, physical value, psychological value, and social value have positive effects on satisfaction of participation. Second, value of personality, psychological value, value of entertainment and physical value have positive effects on intention to adhere to exercise.

The purpose of this study was to examine the impact of Science Writing Heuristic (SWH) on multiple representations in students' writing and to survey experimental group students' recognition about the use of multiple representations. For this study, Participants of this study were 158 students in 7th grade. 94 students were assigned to the experimental group and 64 students were assigned to the comparative group. The experimental group showed significantly higher mean score than comparative group at utilizing multiple representation in summary writing. Interview analysis indicated that all students who participated in interviews, regardless of solid multi-modal competency, recognized that use of multiple representations with appropriate explanations enable to communicate science information persuasively.

This paper investigated the hypotheses about how the degree of IT mentoring program satisfaction can be affected by mentors' competence, college students' participation, and professors' interests in the field of information technology. First, empirical results showed that IT mentoring program satisfaction could be improved when mentors' competence and authenticity exposed to college students. Second, another finding is that IT Mentoring Program satisfaction is significantly positive in the field of both SW and HW. Finally, the role of IT mentor is very essential to university-industry collaboration irregardless of government support. However, college students' participation and professors' interests was low when they didn't get government support.

This study is to investigate the effect of the limitation factor in women's marine sports on negotiation strategy and participation decision. we selected out 278 in total by cluster random sampling that are women in their twenties living in Seoul and Gyeonggi areas in 2009. 2009 years 1 July to 30 July were surveyed. There are the following results performed by a frequency analysis, a factor analysis, a reliability analysis, and multiple regression analysis using SPSS Windows 15.0 Version. First, the limitation factor in women's marine sports partially influences on negotiation strategy. Second, the participation limitation factor in women's marine sports partially influences on participation decision. Third, the participation negotiation strategy in women's marine sports partially influences participation decision.
