Conventional current transformers possess many qualities due their simplicity. However, the technological innovations now underway in the field of switchgear and substation control systems tends to underline their drawbacks. New technologies must be developed to provide users with better service quality in terms of precision, operating safety and interoperability. The current transformer presented combines simplicity and the high degree of precision offered by Rogowski coils with the processing possibilities of digital electronics.

The field of lightweight cryptography has developed significantly over recent years and many impressive implementation results have been published. However these results are often concerned with a core computation and when it comes to a real implementation there can be significant hidden overheads. In this paper we consider the case of cryptoGPS and we outline a full implementation that has been fabricated in ASIC. Interestingly, the implementation requirements still remain within the typically-cited limits for on-the-tag cryptography.

The concepts of flexible displays and plastic electronics have become some of the most talked about new product opportunities for direct view flat panel displays in recent years. The potential advantages are frequently cited, but the achievement of commercially viable products will require many significant technological innovations in new materials and manufacturing technology. This paper will provide a very broad overview of the rationale for developing flexible displays, the market drivers, the applicable display technologies, the major hurdles that must be overcome and the required evolution of new manufacturing technologies that are essential for successful commercialization. This is intended to provide the outline and context for the series of presentations on specific aspects in each of these topics that will be delivered and discussed at the Plastic Electronics Special Session of the 2005 IMID conference.

While technological development being rapid, competition among companies have been very intensive over the world. To hold their competitive power or make sustainable development, it is very imperative for them to attempt innovation. But almost of all innovations were followed by people's resistance to change, and many innovation appeared to be not successful. The objective of this paper is to review the topic of resistance to change in the related literature, and look at the relationship between innovation resistance and many variables like CEO's personality, employee's personality, organizational culture, and defensive behavior.

The use and development of nuclear energy has a long history more than 5o years and is facing a rapid changing environment in technological innovations in order to meet the requirements of energy supply, environmental conservation and social and political demands. The innovation of nuclear technologies are also necessary continuously in order to contribute for the progress of national economy and industry development, improvement of public health, progress of nation science and technology and furthermore is very important for the survival of nuclear industry and strengthening of competition of nuclear technologies. Major directions of the innovation of nuclear technologies would be the enhance ment of safety and economy of the use of nuclear energy, securing od nuclear proliferation-resistance, safe management of radioactive wastes, technology development for newly emerging markets and improvement of public health.

Modern warfare has developed into a network based simultaneous and integrated warfare where operations elements are interconnected. Following such change in modern warfare, ROK Army has been making an effort to transform personnel-based military structure into technology-based advanced structure. Considering technological innovations and changes in characteristics of officers and men, ROK Army is developing scientific education and training system to provide demand-focused customized education. To support such transformation in education and training, ROK Army is constantly developing Army training system using advanced M&S technology. This paper describes ROK Army's education and training policy, and elaborates the current status of M&S training system using advanced M&S technology. This paper further discusses the future directions of M&S training system.

A 3D CAD is one of latest innovations in apparel industry. Despite a rapid progress of related technologies and an emergence of several commercial products in markets, an adoption of 3D CAD tools in apparel industry is much slower than originally expected. In an effort to diffuse such a technological advance in apparel industry, more behavioral studies of why and how apparel designers adopt and use a 3D CAD are needed. Toward that goal, this study aims to identify more about whether such an adoption decision would be more associated with organizations or individuals. Using TAM and TOE framework, the study findings show that the intention to adopt 3D garment CAD is more explained by individual attitudes rather than organizational characteristics.

This paper presents an elastic/plastic model that neglects strain hardening during loading, but accounts for the Bauschinger effect. These mathematical features of the model represent reasonably well the actual behavior of several materials such as high strength steels. Previous attempts to describe the behavior of this kind of materials have been restricted to a class of boundary value problems in which the state of stress in the plastic region is completely controlled by the yield stress in tension or torsion. In particular, the yield stress is supposed to be constant during loading and the forward plastic strain reduces the yield stress to be used to describe reversed yielding. The new model generalizes this approach on plane stress problems assuming that the material obeys the von Mises yield criterion during loading. Then, the model is adopted to describe reversed yielding in thin hollow discs subject to external pressure.

In the advent of the fourth industrial revolution, which was to become an innovative society, we now face the forefront of a technological revolution, and in response to these changes, the world is actively developing the maker movement to nurture new innovations. Accordingly, it is necessary to change the functions of the library in order to play a leading role in a changing life environment. In addition, it is necessary to present certain directions in policies in order to help expand the library's capabilities to utilize a cultural technology. In this study, we have conducted a survey on public library librarians' perceptions towards makerspaces, and based on this, we have proposed directions and support policies for public library's makerspaces and a dissemination structure of makerspaces for the public library.

This paper is concerned with the deployment of core technologies for automotive steel sheets, based on the structural change of global market. The main tasks of automotive industry are to ensure the energy consumption, environmental regulations, and driving safety. With social and legal requirements, this study analyzes the market creation processes with technological innovations for hot rolled, cold rolled and galvanized steel sheets during the 20th century. It has been proven that the leading country in the steel industry was also that in the automotive. The purchaser-supplier relations of sheet materials are then patternized in the regional markets of the United States and Japan, who share nearly 50% of market in the world. According to the paradigm shift of globalization, the balance of power in Porter's 5 forces has been moved to the buyers', and both industries pursue Win-Win strategies such as the PNGV(Partnership for a New Generation of Vehicles ) and design-in system with the competition.
