  • Because of development of information communication and multimedia technology, the focus of M2M(Machine to Machine) intelligent network, multimedia collaboration environment, and transportation safety service is increased. This paper describes a multimedia replicated architecture based on Shepherd environment for transportation safety service. The relationship of information collection and utility is relationship of man to man, but is developed object to object by information communication and control system. This paper suggests a design of multimedia cyber collaboration environment based on M2M. This structure can make multimedia collaboration environment and fault tolerance, so on easily. Because M2M system does not affected to all system in spite of occurring to fault to a node or resource, it has a good condition for design of transportation safety service running on M2M.

  • This study aims to identify the structural relationship between mastery-approach goal orientation, instructor support, problem solving, collaborative skills, and course satisfaction among students who participated in project-based learning. To achieve the purpose of this research, researchers have conducted surveys between June and December in 2019. A total of 283 cases were selected for analysis. According to the study, mastery-approach goal orientation and instructor support have positive effects on problem solving and course satisfaction. Instructor support has positive effects on collaboration skills, and problem solving has positive effects on collaboration skills and course satisfaction. Also, the mediating effect of problem solving in the relationship among mastery-approach goal orientation, instructor support, collaboration skills, and course satisfaction was found to be statistically significant. However, the path between mastery-approach goal orientation and collaboration skills was not statistically significant. Based on these findings, academic and practical implications were suggested.

  • As an IETF standard protocol, WebDAV provides infrastructure for managing and authoring resources and supports asynchronous collaborative authoring on the Web. The CoSlide server is an extension of the Jakarta Slide WebDAV server, providing various workspaces and collaborative services through the WebDAV protocol. The CoSlide server supports workspaces for storing and sharing information of various users, and provides environment for effective collaborative authoring. Actual collaboration activities are performed through a collaboration client software which provides collaboration services along with the CoSlide server. In this paper, we describe the development of the CoSpace client which operates in association with the CoSlide server, presenting effective collaborative environment. The CoSpace client provides user interfaces for accessing and controlling the resources of each workspace on the CoSlide server. In particular, CoSpace provides the facility to launch an authoring application from its workspace view, automatic locking, and downloading the content to be edited, and resource movement using mouse drag & drop.

  • Lam Dong Province of Vietnam has an exceptional diversity of orchids and herbs. At least 920 herb species are widely mentioned in Vietnamese traditional medicinal literature and over 239 Lam Dong wild orchid species are used for attention under the Conservation Vietnamese wild orchids projects. In collaboration with Department of Plant Biotechnology, Dongguk University - South Korea working under supported ODA funds from Korea government (MIFAFF), we will consider how to collecting and preserving these plants in situ or conservating in vitro as a genetic resource.

  • This paper studies the distributed energy efficient resource management in the Internet of Things (IoT). Wireless communication networks support the IoT without limitation of distance and location, which significantly impels its development. We study the communication channel and energy management in the wireless communication network supported IoT to improve the ability of connection, communication, share and collaboration, by using the game theory and distributed learning algorithm. First, we formulate an energy efficient neighbor collaborative game model and prove that the proposed game is an exact potential game. Second, we design a distributed energy efficient channel selection learning algorithm to obtain the global optimum in a distributed manner. We prove that the proposed algorithm will asymptotically converge to the global optimum with geometric speed. Finally, we make the simulations to verify the theoretic analysis and the performance of proposed algorithm.

  • Autonomous and intelligent resource model (AIR-model) defines a building-block of complex systems to pursue value creation by means of diverse resources, referred to as an AIR-unit, and presents a collaboration model with the AIR-units. An AIR-unit represents a piece of resources, such as machines, labor, raw materials, and other assets, considered individually by a complex system as means to accomplish given tasks. It is defined with its own service capability and a goal, and pursues achieving the goal by means of the capability. Moreover, an Air-unit is equipped with autonomy and intelligence, whereby it makes a decision on its course of action on its own initiative. Air-units collaborate on system operations with each other through goal-oriented negotiations. In this research, distinctive features of the AIR-model are addressed and described in detail. Principal components of the AIR-model are also designed via object-oriented modeling techniques. A prototype system based on the AIR-model is finally presented as an embodiment tool of a fractal manufacturing system (FrMS).

  • A system for providing a distributed device resource-object-connection service based on a service delivery platform (SDP) is described. The system includes an SDP and proxy. The SDP configures to define distributed service functions as enablers, generates a convergence service by combining the enablers, and provides the generated convergence service. The proxy configures to connect a distributed device and an SDP to allow the SDP to use the distributed device as a resource, and define and use the distributed device as an enabler. The system are capable of defining distributed service functions as well as distributed sensors as enablers, and thereby allowing the distributed sensors to be used in the same sense as service-function enablers.

  • Previous researches on scalability problem of distributed virtual environment (DVE) have been mainly focused on spatial partitioning of area of interest (AOI). Congestion phenomena by avatar groups in AOI have been neglected relatively However, AOI congestion is highly related to scalability of DVE because it exhausts system resources such as network bandwidth and rendering time, and could be a bar to perform collaboration among participants. In this paper, this will be defined as the problem that must be solved for the realization of the scalable DVE, and a model will be proposed to measure and control congestion situation in AOI. The purposes of the proposed model are to prevent high density of participants in AOI, and to protect stable collaboration in DVE. For evaluation of the performance it is compared with a previous method by defining the resource cost model which is dynamically activated to AOI congestion.
