A better knowledge of emission inventories can serve several important functions such as provision of public information, identification of primary sources, assessment of temporal and spatial trend, and analysis for national modelling studies. The purpose of this paper is to propose the new air emission source categories on the basis of the Korea Standard Industrial Classification. Hence, the paper focuses on reviewing and comparing the air emission sources categories of USEPA, and EU. The new emission source categories compose Tiers 1, 2, and 3. For Tier 1, there are 14 categories; fuel combustion-utilities, industries, and heating and others, chemical and allied product manufacturing, metals processing, and petroleum and related industries, etc. Tier 2 consists of small categories classified minutely in Tier 1. Tier 3 connects the categories of Tier 2 with the Korea Standard Industrial Classification.

In this paper, we propose Neuro-Fuzzy discrimination method of the new and old bill using bill money acoustic data. The concept of the histogram is introduced to improve the processing time into the proposal system. The adaptative filter is used in order to remove the motor sound from an observed bill money acoustic data. The output signal of this adaptive digital filter is converted into not only a spectrum but also a histogram. It became easy that features of the paper money sound were extracted from the bill money acoustic data. The spectral data and the histogram is obtained like this, and it become an input pattern of the neural network(NN). Then, the discrimination result of the NN is finally judged by the fuzzy inferece in the new bill or the exhaustion bill.

Information technology is a useful strategic weapon that can create competitive advantage and new business opportunity by applying it in the organization' value chain. IT convergence can be understood as an attempt of industrial level IT adoption to facilitate the innovation of the industry and the birth of a new industry. This study provides the comprehensive review of the Korean government' three IT assimilation programs, ubiquitous technology diffusion program of the Ministry of Knowledge Economy, u-service program of the Ministry of Public Administration and Security, and u-Defence cooperation program of the Department of Defense. The analysis is done through the interpretation of the existing literature and the logic model. The result proposes inter-agency cooperation and building of new technology road-map in the planning stage, flexible management in the execution phase, and failure tolerant evaluation system. The proposal for developing competencies and institutional foundations for IT convergence also presented.

Design structure of a mobile phone has been changed to a converged style, which has so many functions. However, the converged mobile phone could not satisfy the users who want to use only specific functions, so with Axiomatic Design, we have studied for making a proposal to set up the new concept. The goal of this study is to derive a general solution with Axiomatic Design to verify the Independence. By enhancing the existing design model and differentiating the function of mobile phone, user will be able to choose desirable products, which have only specific functions and/or specific parts. First of all, we checked the Independence about the existing design model. Then, we developed the new design model with the idea that base mobile phone should have basic functions and additional functions can be separated, surely be connected when users want.

Advanced nuclear power plants are generally large complex systems automated by computers. Whenever a rare plant emergency occurs the plant operators must cope with the emergency under severe mental stress without committing any fatal errors. Furthermore, The operators must train to improve and maintain their ability to cope with every conceivable situation, though it is almost impossible to be fully prepared for an infinite variety of situations. In view of the limited capability of operators in emergency situations, there has been a new approach to preventing the human error caused by improper human-machine interaction. The new approach has been triggered by the introduction of advanced information systems that help operators recognize and counteract plant emergencies. In this paper, the adverse effect of automation in human-machine systems is explained. The discussion then focuses on how to configure a joint human-machine system for ideal human-machine interaction. Finally, there is a new proposal on how to organize technologies that recognize the different states of such a joint human-machine system.

In this appear, we proposed the new current mirror has large output resistance and excellent current matching characteristics. If supply voltage were lowered under the conventional CMOS operational amplifier, the wing of out put power could be restricted. So, the paper suggests a new way of differential operational amplifier circuit to solve the problem. The paper proposes that a new current mirror increases output swing and has a stable operation. We compare and verify characteristics of the proposed current mirror with the cascoded current mirror and the regulated current mirror through simulation.

The parameters such as Richardson numbers or stability parameters are widely used to account for the extra straining effects due to three-dimensionality, curvature, rotation, swirl and others arising in paractical complex flows. Existing expressions for the extra strain in turbulence models such as $k-{\epsilon}$ models, however, do not satisfy the tensor invariant condition representing the coordinate indifference. In the present paper, considering the characteristics of both the mean strain rate and the mean vorticity, a new parameter to deal with the extra straining effects is proposed. The new parameter has a simple form and satisfies the tensor invariant condition. A semi-quantitative analysis between the present and previous parameters for several typical complex flows suggests that the newly proposed parameter is more general and adequate in representing the extra straining effects than the previous ad-hoc parameters.

As a seedbed for American Public Administration, Traditional Reform Perspective (TRP) produced Wilsonian formulation of administrative science in modern academic setting. From the beginning of the second half of the twentieth century, ideas were transported into Public Administration scholarship. New Reform Perspective (NRP) entails a belief that these reasonings are largely based on assumptions of Economics. Looking into this belief is a necessary condition, if not a sufficient one, for answering the question: Does NRP hold in the study of administration? This initial reading, though somewhat primitive, tries to set up a proposal for identifying a meaningful context for understanding the situation. As a representative version, Wilson's original perspective must be reconsidered in order to articulate the field of study within traditional reform context. According to NRP, new administrative theories are the results of the influence of economic reasoning into the field of Public Administration. Therefore, rereading of Tiebout's 'Pure Theory' and Ostrom, Tiebout and Warrens's 'Theoretical Inquiry' is a prerequisite to satisfy this particular condition.

The purpose of this study is to examine interventions and supporting systems by dementia stage, take a look at dementia insurance policies in Korea and the United States, and present Korean private insurance programs for dementia patients. According to the study, our suggestions of a design of private insurance products for Korean dementia patients are as follows. First, the products should support people aged 80 and older. Second, new products should include the mild stage dementia in the insurance coverage. Third, non-pharmacological treatments, such as the cognitive stimulation, the cognitive training, and exercises need to be covered through the new private insurance. Fourth, the private insurance should be contained home health care services in its coverage. These suggestions can reduce the dependence of the public insurance, help people choose appropriate treatments for themselves, and give people a good opportunity to improve the effect of dementia treatment and to increase the satisfaction of patients and their families.
