For temporal relations of interactive media such as MPEG-4, it is necessary for a temporal model that can update dynamically presentation time and temporal relations among objects by user events occurring during playback. Also, 811hough the temporal attributes are changed by user events, the validity of scene must be maintained. In this paper, we propose a temporal model that supports user interaction and developed an MPES-4 contents authoring system applying this model. We define the temporal relations of MPEG-4 that tan be authored and user interactions that can change the temporal properties. This authoring system defines the constraints on temporal relations and events and can generate the scene without error by checking the constraints. Also it provides the authoring environment to author visual]y temporal relations and events in MPEG-4 scene and generates the MPEG-4 stream by encoding the authored scene.

This paper is concerned with development of a communication module of POFS(Parallel Operating File System), which is the parallel file system to be operated on SPAX computer. SPAX is multiprocessor computer with clustering SMP architecture and being developed by ETRI. The operating system for SPAX is MISIX based on the Chorus microkernel. POFS has client/server architecture basically so that it is important to design a communication module. The communication module is so easily affected by network environment that bad design is the major reason that decreases the portability and performance of the parallel file system. This paper describes the structure and performance of the communication of the POFS. the theme is issued in the course of designing and developing POFS. The communication module of POFS was designed to support the portability and the architecture of parallel file system.

Recently, one of the most challenging problems is to compose web services dynamically, that is, on demand. A number of researchers have been considerably interested in the dynamic web services composition. However, while most of them focused on the semi-automatic web services composition with a human controller, very little attention was devoted to the full automation of this process. This paper primarily focuses on the automatic web services composition techniques. The main idea is to implement an automatic web services composition system using web ontologies to realize the semantic web and workflow technologies to play a major role in E-businesses. In this paper, we propose a matching algorithm for web service discovery and present an approach based on the use of ontologies to facilitate the interoperability of web services. Finally, we describe a workflow execution plan to support the automatic web services composition, and an experimental study that shows the high performance of our system.

Studies on Appreciative Leadership have recently started in Korea as well. A leader in Appreciative Leadership is defined as a person who can effectively handle a mixture of various styles of leadership and suggest advice and future directions (Withney and Trosten-Bloom, 2010). Also, Appreciative Leadership can be explained as one way of appreciative leadership behavior which enables constructive accomplishment of mutually creative tasks for future through growth based on individuals' strengths, as well as a shared value system with organizational goals for all (Withney and Trosten-Bloom, 2010). Appreciative Leadership leads members of an organization toward positive inquiries and open discussions so that they become fully engaged in the organization while Appreciative Leader motivates and inspires his/her members and enables them to feel that they are of value to the organization. Study results show that Inspiration among sub factors of Appreciative Leadership has a positive impact on employees' engagement in the organization and their tasks while Inquiry positively influences in employees' organizational engagement.

Linear interpolation is a basic sampling method for volume visualization. This method generates good images but sometimes it is inferior to our high expectation because it is encouraged to produce high quality images in the medical applications. In this paper, B spline based tri-cubic interpolation is used for the re-sampling step. The conventional B spline is an approximation method which does not cross control points so that we moved the control points and the curve crosses the original control points. In the rendering step, the empty space leaping is applicable to increase rendering speed. We have to calculate the maximum and minimum values for each block to detect empty space. The convex hull property of B spline enables the values of control points to be used as the maximum and minimum values. As a result, tri-cubic interpolated volume rendering is possible in interactive speed.

New systems and management strategies have been successfully settled in order to be linked to enhancing organizational performance internalization process. The most successful methods for internalization are training and communication strategies. However, the organization must be supported by trust and cooperation cultures for successful education and communication. In this study, we measured the degree of internalization of organized vision, and core values. And then, a successful convergence business strategy internalization plan was presented. Strengthening training plan, communication strategies and management strategies must be internalized in parallel with seeking a change of organizational culture. First, iterative learning is very effective in order to strengthen education and management strategies through talking frequently. Second, chief executive officer should pay attention to communication with employees for the internalization. Finally, in order to change the organizational culture, organizational leaders will establish strategic plan to build open and collaborative culture among colleagues and quantitative and qualitative expansion of the human network.
