To efficiently manage the supply chain of an industry, the structure and characteristics of a supply chain have to be predefined and it is strongly required to get a framework to analyze a supply chain. We have developed a framework to analyze a supply chain from the viewpoint of chain relationship. It is possible to evaluate the degree of supply chain of each entity by using the framework. We have applied the framework to the port & logistics industry. From this research, we have identified tile current status of supply chain of port & logistics industry in the Korea and extracted some considerations for the healthy supply chain of Korean port & logistics industry.

The main purpose of this paper is to propose a sophistication framework for a global manufacturing network (GMN) driven by a mother company to autonomously propagate and coordinate transaction data that are exchanged among manufacturing partners. The framework is based on conceptual fundamentals of previous research that provide a step toward ultimate successful collaboration in the supply chain and employs mobile agents for the coordination and propagation of transaction data. Maintaining the integrity of transaction data linked to a huge information web is difficult. With the sophistication functionalities of this framework, it becomes easy to effectively control the overall GMN operations and to accomplish the intended goals. The current level of sophistication focuses on the transaction data propagation. The sophistication level may be expanded up to business intelligence in the future.

Innovation Cosystems are Conceptualized as Organizational Networks of Economic Actors, Technologies and Social Contexts that Interact for Knowledge Production, use, and Adaptation. This Paper Proposed a Conceptual Framework to Describe Value Co-creation of Organizational Networks Engaged in Technology Innovation. We Adopted Theory-Based Approach by Integrating the Perspective of Service-Dominant (S-D) Logic Into the Evolutionary Model of the Triple Helix. The Framework Gives a Plausible Explanation on how Actors Collaborate to Create Value in Dynamic Contexts of an Innovation Ecosystem. The Innovation Ecosystem can be Considered as a Composite of Sub-Ecosystems, Including Knowledge, Sectoral, and Business Ecosystems. When these Sub-Ecosystems are Recursively Transformed by Coordination of Functional Mechanisms that Serve Value Co-creation in the Innovation Process, the Innovation Ecosystem will be Re-Organized and Evolve. The case of the Digital Living Network Alliance (DLNA) was Examined to Demonstrate the Fundamental Mechanisms for Value Co-creation that was Described in the Framework. The case Study Indicates Features of Value Co-creation when Implementing Innovation in Organizational Networks.

Recently, collaborations through MCS use in team projects are frequently conducted. This study developed a research model to examine the impact of collaboration through MCS on project performance. Team commitment and team trust regarded as the key drivers of enhancing project performance. Moreover, we also investigated the effect of usefulness of MCS on project performance. We posit ubiquity, polychronic use, and ease of use as the key antecedents of usefulness of MCS. The proposed theoretical framework was tested by using survey data collected from 116 university students who have rich experience with collaboration through MCS. PLS was employed for the analysis of the data. The analysis results showed that team trust significantly influences team commitment and project performance, respectively. However, usefulness of MCS is not significantly related to team commitment, while it play a prominent role in enhancing project performance. The results reveals that ease of use has a significant effect on usefulness of MCS, whereas ubiquity and polychronic use are not significantly related to it. From theoretical and practical perspective, this paper can provide in-depth knowledge of the effects of collaboration via MCS on project performance.

We propose ESS_WMCE. This paper explains the design and implementation of the EDSS running on ESS_WMCE. EDSS is a synchronization error control system for web based multimedia collaboration environment. We have an error detection approach by using hooking method. The technique of an error transmission is a mended model of utilizing an application sharing system. DOORAE is a good framework model for supporting development on application for computer supported cooperated works. It has primitive service functions. Service functions are implemented with an object oriented concept. It is a system that is suitable for detecting and sharing a software error rapidly occurring on web based multimedia collaboration environment by using software techniques. It is able to share an error as well as providing URL synchronization to access shared objects. When an error occurs, this system detects an error by using hooking methods in MS-Windows API(Application Program Interface) function. If an error is found, it is able to provide an error sharing to access shared objects.

Construction Projects have mutual collaborative structures among various participants for common objectives. Most of all the design project which is the initial phase in the project is crucial for determining project overall quality and requires intimate and continuous relations between project participants. Thus, this study suggests Design Collaboration Management System for successful performing projects through cooperation among participants in the initial stage of projects. First, expert interviews were performed to figure out present conditions of design collaboration management and problems. The factor analysis was applied to draw owner's collaboration factors and engineer's collaboration factors. Based on those factors, this study suggests design cooperation management process which gives a framework for systematic management method. Through the process the design collaboration management system was developed which helps owner/designers/engineer's co-work. The System suggested from this study realizes systematic information management tool and through that it is expected to improve design product;'s quality, and further contribute the advancement of project.

European Material Test Reactors (MTRs) have provided essential support for nuclear power programs over the last 40 years. MTRs are now ageing in Europe and they cannot ensure the securing of experimental capability for the next decades. In this context, a new Material Testing Reactor, named Jules Horowitz Reactor -JHR-, operated as an international user-facility, is under development in Europe. The European MTRs context and the JHR objectives and status will be presented. Emphasis will be put on experiments in the field of nuclear fuels and materials irradiation which are developed in the framework of European and international collaboration.

This paper gives a brief overview of the COMS CPS development process from start to finish. The manufacturing techniques used for CPS were founded on established generic processes that have been developed and proven on previous satellite programs, and have used the expertise and facilities in the framework of international collaboration. Manufacture and testing of the CPS were successfully accomplished, and COMS CPS demonstrated good performance in the launch phase.
