This study examined the mediating effects of perceived organizational support (POS) on the relationship between the person-job fit and job satisfaction of service workers. POS is divided into socioemotional POS and instrumental POS. To achieve the research purpose, a questionnaire survey was conducted on workers in charge of service jobs in domestic companies through an on-line survey system and finally, the results of 281 respondents were analyzed to verify the hypothesized research model with an 80.3% effective recovery rate. The findings are as follows. First, the person-job fit has positive effects on job satisfaction and POS. Second, among the sub-constructs of POS, socioemotional support has mediating effects, but instrumental support has no mediating effects on the relationship between person-job fit and job satisfaction. Based on the results of this study, this study suggests theoretical and practical implications for the human resource development and management of service workers. Overall, changes in the recruitment system, which can judge the person-job fit of employees who perform emotional labor facing customers, organizational culture and personnel system for establishing socioemotional support system, and compensation and workforce development system, are needed to enhance the job satisfaction of service workers.

Understanding the cultures of other countries is not as fast as the speed of internationalization. As globalization advances, interest and research on the characteristics of national culture differences have been increasing. One of the important challenges for business leaders is the ability to understand and deal with cross-cultural management. But there is a lack of research on cross-cultural management and suitable type of leadership. In order to achieve this objective, this study, adopts Hofstede cultural dimensions, and finds the impact of these kinds of leadership on organizational performance. Feminism, collectivism, power distance, and uncertainty avoidance were classified into four factors of cultural orientation that affect the selection of initiating structure and consideration leadership. In this research, among virtue factors of leadership, structure initiation and leadership consideration are focused on how to affect organizational effectiveness of the result factor by national culture. This research has concentrated on how leadership-styles among national-cultures have influence on organizational-effectiveness.

Information system, organization structure, and business strategy have been major variables in MIS research. Most of research about these variables interested in the relationship of two variables. There were very few efforts to connect three variables. But relationship or fitness of these factors plays an important role to improve performance. Nowadays managers face new challenge. That is 'globalization' To cope with this turbulent environment, they have to know how to fit these Important factors(information system, organization structure, business strategy). It is the main purpose of this article to find out the fitness of these variables under global business environment. Based on literature review, I made research model which tells whether fitness of three variables affects performance under the control of headquarter. And I propose hypothesis. I define strategy as global innovator, integrated player, implementers role, local innovator and organization structure as multinational, global, international, trans-national and information system as independent IT operation, headquarter driven configuration, intellectual synergy configuration, global integrated IT configuration.

It is required for enterprises to construct the proper information management system in order to cope with the volatile business situations. The mobile office system is introduced from the needs to provide organization members smart information and mobility. By setting the model, hence, we intend to scrutinize the impact of the task-technology fit model and organizational characteristics of the mobile office system on the job performance. As a result, system quality, information quality and mobility are revealed to affect positively the task-technology fitness and the fitness also affects the job performance positively. Organization characteristics affects the job performance positively through the task-technology fitness, too. Therefore the organization which plans to introduce the mobile office system should consider the task-technology fitness and exert organizational-level efforts to adopt and use the mobile office system in the workplace.

The intelligent trajectory control method that controls moving direction and average velocity for a prosthetic arm is proposed by pattern recognition and force estimations using EMG signals. Also, we propose the real time trajectory planning method which generates continuous accelleration paths using 3 stage linear filters to minimize the impact to human body induced by arm motions and to reduce the muscle fatigue. We use combination of MLP and fuzzy filter for pattern recognition to estimate the direction of a muscle and Hogan`s method for the force estimation. EMG signals are acquired by using a amputation simulator and 2 dimensional joystick motion. The simulation results of proposed prosthetic arm control system using the EMf signals show that the arm is effectively followed the desired trajectory depended on estimated force and direction of muscle movements.

As information security(IS) is recognized as a critical success factor for organizational growth, organizations are increasing their investment in adopting and operating strict IS policies and technologies. However, when strict IS technology is adopted, IS-related techno-stress may occur in the employees who apply IS technology to their tasks. This study proposes the effect of IS-related techno-stress formed in individuals on IS policy resistance through IS strain and proves that task-technology fit mitigates the negative effect of techno-stress. Research models and hypotheses were presented through previous studies, and the secured samples were used, and structural equation modeling was applied to verify hypothesis. As a result of the study, it was confirmed that IS-related techno-stress (overload, complexity) affected IS policy resistance through IS strain (anxiety, fatigue), and that task-technology fit moderated the relationship between techno-stress and strain. This study suggests a strategic direction for improving the level of internal IS from the viewpoint of suggesting ways to mitigate the stress of employees that may occur when IS policies and technologies are adopted.
