Most of the current mobility management protocols such as MIPv4/6 and its variants standardized by the IETF do not support global seamless handover. This is because they require comprehensive changes of the existing network infrastructure. In this article, we propose a simple mobility management protocol (SMMP) which can support global seamless handover between homogeneous or heterogeneous wireless networks. The idea is that the SMMP employs separate location management function as done in SIP to support global user and service mobility. In addition, the bidirectional tunnels are dynamically constructed to support seamless IP mobility by extending the IEEE 802.21 MIH standards. The detailed architecture and functions of the SMMP have been designed. Finally, the simulation results, using NS-2, show that the proposed SMMP outperforms the existing MIPv6 and HMIPv6 in terms of handover latency, packet loss, pear signal noise ratio (PSNR).

This study proposes the O P E N Triad framework as a future set of tools and perspectives for individual members and institutes to further their professional and academic potential as well as prospect and vitalize the future of the Korean Clothing and Textiles discipline through a global perspective. The millennial generation desires On-demand, Personal, Engaging, and Networked (O P E N) experiences effecting cultural change for creative and influential interaction in transactions, communication, and education. O P E N Individuals offers a WebSphere model as a holistic learning system that has a synergizing value of education across academic courses, industries, and cultures. Through a digitalized and virtualized class, it complements relevant technologies already familiar to the student population. By employing environmental scanning approaches, the most influential and viable future global issues related to the clothing and textiles discipline are identified and dialogued within O P E N Institutes. For future clothing and textiles institutes, this scanning allows them to be open to new ideas, to focus on inter-engagements, to collaborate among individuals, to associate as a part of web of people, organizations, and ideas, to personalize an institutes curricula, and to dialogue generative knowledge. O P E N Industries reveals three dominant future issues that cross academia and industry, sustainability, supply chain management, and social networking. In-depth interviews with U.S. industry experts identified interdependent gaps in global consumer experience practices and suggested the following gaps as future research areas: a standardized business model to the entrepreneurial model, strategic management to a sustainable competitive advantage, standardized to differentiated products, services and operations, market segmentation to global consumer clusters, business-driven marketplaces to consumer-engaged marketspaces, and excellent services to optimal experience. This O P E N Triad framework empowers millennial students, universities, and industries to anticipate and prepare for a radically changing world.

Global e-SCM (electronic Supply Chain Management) has become an important business strategy in a rapidly changing global competition environment. It encompasses both domestic business and overseas business. Overseas business, including B2B and B2G, involves the complex trade procedures across countries. So, the standardization of electronic documents (messages) and business processes is one of critical factors for the successful implementation of global e-SCM. Without standardized messages and streamlined business processes, the benefits of global e-SCM would not be guaranteed because of human intervention like re-keying business data, which may create errors, delay processes, cause additional data or procedures, etc. Thus, this paper is to review the implementation challenges of Global e-SCM, to address the needs for electronic information flows through the standardization in electronic documents and business processes for fast and accurate trade transactions in the global supply chain activities, and to assert the importance of adoption of international standards.

The impact of industry characteristics on born global firms'internationalization process is widely acknowledged. Even though there are studies focusing on other industries, the franchise industry's internationalization patterns have not been generally analyzed. Through a multiple case-study research focusing on a comparison between franchise and other industries, we are able to define "born-global franchise" in the internationalization pattern and specific influential factors. Our findings show that (1) leadership and creativity of executive, (2) learning orientation and technology orientation, (3) differentiated proprietary technology (4) observation of the surrounding environment.

Environmental problems like global warming have now become important issues that should be considered in all industries, including construction. In South Korea, many studies have been conducted to achieve the government's goals of reduction in environmental impacts. However, the research on buildings has only focused on CO₂ emission as a research target despite the fact that other environmental impacts resulting from ozone depletion and acidification should also be considered, in addition to global warming. In this regard, this study attempted to propose assessment criteria and methods to evaluate the environmental performance of the structures from various aspects. The environmental impact category can be divided into global impacts, regional impacts, and local impacts. First, global impacts include global warming, ozone layer depletion, and abiotic resource depletion, while regional impacts include acidification, eutrophication, and photochemical oxidation. In addition, noise and vibration occurring in the building construction phase are defined as local impacts. The evaluation methods on the eight environmental impacts will be proposed after analyzing existing studies, and the methods representing each environmental load as monetary value will be presented. The methods presented in this study will present benefits that can be obtained through green buildings with a clear quantitative assessment on structures. Ultimately, it is expected that if the effects of green buildings are clearly presented through the findings of this study, the greening of structures will be actively expanded.

Since the commercial operation of Kori Unit 1 in 1978, South Korea has been at the forefront of nuclear power plant construction for nearly 40 years. South Korea have constructed 27 nuclear power plants domestically and an additional 4 plants in the UAE. Leveraging this extensive experience, the country has developed and operated a nuclear power plant construction management system with a focuse on procedures and processes development, along with a user-friendly approach. The initial nuclear power plant construction management system operated was NPCS (Nuclear Power Plant Construction System), which was based on drawing inquiries. Subsequently, a system centered on construction project management, known as NPCMS (Nuclear Power Plant Construction Management System), was established and operated. In 2009, through the export of nuclear power plant construction to the UAE, research on advancing construction management led to the implementation of INPCMS(Integrated Nuclear Power Construction Management System), which is functionally enhanced. Over time, in response to changes in the construction environment, demands from international operators, and alignment with global standards, South Korea is in the process of redeveloping its INPCMS. This aims to establish a global nuclear power plant construction management system, outlining key features and future directions.

This study empirically analyze efficiency and productivity changes of public hospitals of Korea using data envelopment analysis/Window model and global Malmquist indices model. We use the ten-year data from 2001 to 2010 of 30 regional public hospitals listed database from the Association of Korean Regional Public Hospitals. The main focuses are to reveal whether the technical inefficiency are improved as time goes by, and efficiency and productivity are affected by environmental factors. The results can be summarized as follows. First, the efficiencies of public hospitals rise in trend as time passes. Second, regional public hospitals show the different average efficiencies according to their regional type, hospital type, operational type, medicaid type, and demand and supply conditions by Mann-Whitney U-tests. Third, technical efficiency changes mainly contribute to 4.4% annual average growth rate of productivity of regional public hospitals during that period. Our findings have some policy implications. It is confirmed that there exist some environmental inefficiencies, and those inefficiencies can not be overcome through just improving the inner management system. Thus, policy and institutional changes are necessary for regional public hospitals to improve efficiency and productivity overall.

Global companies are building global production network for the demand of the global market. However, the establishment and operation of overseas plants make the unexpected case like theft, low will to produce and salary issue of local workers. Thus in this paper, we propose the raw materials loss prevention model based on IP Camera and RFID Box for raw materials management of overseas plants. This model can prevent the theft or loss of raw materials write inventory up in real-time. This model can be allows us to realize the cost-effective production management because it enables remote inventory management. And this model can prevent brand image danage and profit loss due to reject product.
