A study on the structural change in the U.S. textile industry. The U.S. textile industry has undergone significant changes over the last fifty years, including a steady decline in the relative scale of domestic production, employment reduction, and increased competition from imported products. In order to weather a crisis, the responses of the U.S. textile industry have been made such as investment in technology, specalization in the textile and apparel industries. The textile and apparel industries have taken steps to increase labor productivity through automations to speed management to create and introduce new products and new methods, and have lowered indirect overhead costs. Regarding these response of the U.S. and other situation of world textile and apparel trade market, much of the sense of crisis that pervades korean textile and apparel industries has to do with the problem of adjusting corporate policy.

It is generally known that electrochemical impedance spectroscopy is a powerful technique and its real-time application has been demanded for prompt observations on instantaneous electrochemical changes. Nevertheless, long measurement time and laborious analysis procedures have hindered development of it. Solving the problems, here I report of a new algorithm design for development of a real-time electrochemical impedance monitoring system, which potentially provides a guideline in developing monitoring systems of electric vehicles batteries and other electrochemical power plants. The significant progress in this report is employment of the parallel processing protocol which connects independent sub functions to successfully operate with avoiding mutual interruptions. Therefore, all the processes required to monitor electrochemical impedance changes in realtime are properly operated. To realize the conceptual scheme, a Labview program was coded with sub functions units which conduct their processes individually and only data are transferred between them through the parallel pipelines. Finally, measured impedance spectra and analysis results are displayed, which are synchronized according to the time of change.

Because of new requirements related to the employment of SMT(Surface Mounting Technology) manufacturing and the diversity of components on high density PCB(printed circuit boards), Thermal control of the reflow process is required in oder to achieve acceptable yields and reliability of SMT assemblies. Accurate control of the temperature distribution during the reflow process is one of the major requirements, especially in lead-free assembly. This study has been performed for reflow process using the commercial CFD tool(Fluent) for predicting flow and temperature distributions. There was flow recirculation region that had a weak point in the temperature uniformity. Porous plate was installed to prevent and minimize flow recirculation region for acquiring uniform temperature in oven. This paper provided design concept from CFD results of the steady state temperature distribution and flow field inside a reflow oven.

Traditional housing must be conserved simultaneously with not only the building itself, but the circumstances of the surroundings. Hence, traditional housing should be developed as a product of a culture environment. However, most cultural properties have recently been treated as only a piece of property by irresponsible maintenance practices and damage placed on private traditional housing. Apparently, it has not always been a result of dweller's negligence. Thus, various policies must be needed to effectively preserve traditional housing. To do so, this study will indicate a new direction for the circumstance of preservation through cultural employment of traditional high-class housing as well as reduce maintenance and damage for dweller's convenience. Furthermore, this study will propose a renovation for popularization of Korean cultural assets through the gradual implementation of both economic value and public worth.

In the present study, we propose the framework which directly links shell finite element to the surface geometric modeling. For the development of a robust shell element, partial mixed variational functional is provided. The NURBS is used to generate the general free form of parameterized shell surfaces. Employment of NURBS makes shell finite element handle the arbitrary geometry of the smooth shell surfaces. The proposed shell finite element model linked with NURBS surface representation provides efficiency for design and analysis and can be directly extended to surface shape optimization problems in future work.

In the present study, we visualize the linkage framework between geometric modeling and shell finite element based on B-spline representation. For the development of a consistent shell element, geometrically exact shell elements based on general curvilinear coordinates is provided. The NUBS(Non Uniform B-Spline) is used to generate the general free form shell surfaces. Employment of NUBS makes shell finite element handle the arbitrary geometry of the smooth shell surfaces. The proposed shell finite element .model linked with NUBS surface representation provides efficiency for the integrated design and analysis of shell surface structures. The linkage framework can potentially provide efficient integrated approach to the shape topological design optimizations for shell structures.

Purpose - This paper attempts to provide an understanding of practice of franchising in eight countries - USA, UK, Australia, Brazil, China, Malaysia, South Africa and Nigeria. The bases of the review are: number of systems and outlets, employment generation, annual turnover, GDP contribution, legal and regulatory frameworks and country-specific franchise business practice nuances. Research design, data and methodology - the paper is descriptive, highlighting elements of the business practice that distinguish one country from another. Documentary data - mainly industry publications supplemented by empirical literature - was used for the review. Result - Although there are commonalities in the technical design and implementation of franchise business practice - especially the business model type - differences exist in terms of legal and regulatory frameworks guiding the industry across the eight countries studied. Conclusion - There are no two countries that have the same franchise practices. Franchise markets in the developed, and to some extent, the emerging economies have saturated. Franchise markets in African countries are at infant stage and thus, these countries are strategizing to attract foreign brands into their domains.

This study aims to propose the concept design of oil spill protection robot which can rapidly intervene to control the oil spillage situation at the sea. Taking into account the fact that a huge amount of oil is transported trans-continentally by oil tanker, none of industrialized countries are completely safe from the marine oil spill which results in social, economical and ecological damages to their communities. The employment of double hull-oil tanker, pipe line transporting can be most safe way. Yet complete prevention of oil spill is probably not realistic. Accordingly the alternative solution to control marine oil spill and minimize the damages caused by the incident using intelligent robot technology based on swarm control method is proposed. The main features of oil spill protection(OSP) robot is explained via following three perspectives. Firstly, from functional point of view, OSP robot system safely and efficiently replaces oil boom installation manually conducted by human workers with intelligent robot technology based on swarm control theory. For second, its modular architecture brings efficient storage of main components including oil boom and facilitates maintenance. For the last, its geometric form and shape enables whole system to be installed to helicopter, boat or oil tanker itself with ease and to rapidly deploy the units to the oil spill area.
