The purpose of this study is to analyze the difference of productivity according to environmental factors among 25 Regional base public hospitals. Also this study is to propose a method to improve the productivity of Regional base public hospitals in the future by improving the public performance and stable management performance by studying the productivity variables affecting profitability. The survey period was based on the last three years, and 25 Regional base public hospitals were selected for the survey. The dependent variable is the total capital medical marginal profitability and the medical profit marginal profitability which are the indicators of profitability. The independent variable, productivity, is classified into three indicators: capital productivity, labor productivity, and value added productivity. The ANOVA analysis method was used to analyze the productivity difference according to the frequency factor and the environmental factors of the Regional base public hospitals. Finally, we conducted a hierarchical regression analysis to examine the productivity variables affecting profitability. The results of this study showed that there were differences in productivity due to environmental factors such as hospital size, competition in the local medical market, and differences in management performance. The difference in productivity and profitability depending on the environmental factors suggests that it is difficult for Regional base public hospitals in each regional base to perform a balanced public service. In order to overcome this, it is necessary to provide balanced medical services such as government financial support expansion, regional medical demand forecasting and facility infrastructure construction.

In this article, we propose a typology of industry convergences which encourages to invent new types of products and services through combining technologies across industries and identifying success factors of convergence industries which were resulted by industry convergences. In detail, the proposed typology of industry convergences is analyzed based on three viewpoints such as academic areas that provide the knowledge of convergence technologies, industry structures for the existing markets, and user experiences used for improving user friendliness. Such viewpoints can not only be considered as the sources for convergence industries but also be closely related with success factors of convergence industries. Based on the typology and the success factors of convergence industries, we suggest the implications about policies for the domestic industry convergence. It is expected that the results of this article can be widely applied to further activate industry convergences to overcome the recent global economic downturn.

The purpose of this study was to investigate the influence of physical self-efficacy by a participation of sport leisure activity on general self-efficacy and life satisfaction for women based on the survey data from 174 women participating in swimming program in indoor pools at the area of Daegu and Gyongbuk. With the empirical analysis of the data, this study found the following conclusion. First, physical self-efficacy were significant on all general self-efficacy factors. Thus physical self-efficacy were influenced on pride, interpersonal relations, overcome difficulties, endurance. Second, physical self-efficacy was significant on life satisfaction. thirdly, general self-efficacy was partly significant on life satisfaction. Thus pride, interpersonal relations were not influenced on life satisfaction but influenced on overcome difficulties, endurance. Fourth, in case of the women over 40 years of age, physical self-efficacy was not significant on life satisfaction, and only endurance of general self-efficacy factors was influenced on life satisfaction. Whereas in case of the women under 40 years of age, physical self-efficacy was significant on life satisfaction, and overcome difficulties, endurance general self-efficacy factors were influenced on life satisfaction.

Grounded in the prior literatures on acceptance and diffusion of IT and innovation in the level of organization research, 3 major constructional factors such as Motivation, IT resistance, and IT change management were investigated to suggest propositions from 15 multi-cases of PLM from 6 different companies in Automotive OEMs and suppliers, and we posited that the diffusion is continued only when motivation is stronger enough to overcome IT resistance as a fundamental finding and basis of this research on PLM acceptance and diffusion. The Motivation was found to be initiated and categorized from three different factors such as environmental factors, organizational factors, and technological factors, providing key propositions for further research: (1)The Automotive suppliers, contrary to OEM, are affected more by the demand of inter-connectivity as an environmental factor, while the other factors are similarly influencing to them, (2)The big organizations are influenced more by the champion, while the small organizations get influenced more by leader. (3)When the trend, inter-connectivity and complexity get stronger, the motivation gets more strongly influenced by the perceived benefit in the technological context. Regarding Change management we suggests IT change management is supportive to overcome IT resistance and also to enforce Motivation, and the critical mass exists differently according to the market maturity adopted, and more market matured technology has lower critical mass, implies less requirement of IT change management than less market matured technology.

In this work, we consider the flexible manipulator system. Generally, the manipulator system may often be made on the base of the imperfect modeling, joint friction, payload change, and external disturbances. These elements are uncertain factors. These uncertainties and flexibility make difficult to control the system. To overcome these defects, a class of robust control law is proposed for the flexible manipulator system and the singular perturbation approach is applied. To show the effectiveness of this control law, simulation is presented for one degree of freedom flexible joint and flexible link system.

This paper aims to develope a new algorithm to overcome the disadvantages of the conventional E.L.D system based on the B-Constants and Penalty-Factors scheme. The main features of this paper are that the Variabiable Decoupled Method usually employed in the Load-Flow studies is introduced to the E.L.D. algorithm developed by Sasson, using the Powell's Nonlinear Programming Scheme. Besides this, other minor refinements are made to reduce memory spaces and computing time. Case studies show that the method suggested here has the remarkable advantages of computing efficiency and memory requirements over Sasson's.

Transgenic animal technology has provided new opportunities in many aspects of biotechnology and medicine during two decades. Several gene delivery systems including pronuclear injection, retroviral vectors, sperm vectors, and somatic cell cloning have been tried to generate new functional animals. In the future somatic cell cloning technology will be a major method in the transgenic animal production. Many factors enhancing overall transgenic efficiency should be overcome to facilitate the industrial applications of transgenic technology. Transgenic animal technology has settled down in some areas of the medicine, especially the mass production of pharmaceutical proteins and xenotransplantation. Thus, animal biotechnology will contribute to welfare of human being.
