This study is to comparate on impact factors and moderator of incentives of knowledge transfer between Nonprofit and Profit organization. In nonprofit organization, the results founded that individual information capability, quality of knowledge, and quality of construct were statistically significant in knowledge acquisition, informal communication and quality of construct were statistically significant knowledge sharing, and individual information capability, informal communication, quality of knowledge and quality of construct were statistically significant knowledge use. Also interactive effect of knowledge sharing and Psychological Physical incentive was statistically significant knowledge use. In profit organization, the results founded that individual information capability, informal communication, quality of knowledge, and quality of construct were statistically significant in knowledge acquisition, quality of knowledge and quality of construct were statistically significant knowledge sharing, and individual information capability, informal communication, and formal communication were statistically significant knowledge use. Also interactive effect of knowledge acquisition and Psychological Physical incentive was statistically significant knowledge use.

'Interactivity' is considered as a key factor of user-centered interactive instructional systems design in Web environments. To provide an optimal level of interactivity for learners is an ideal goal in instructional systems design(ISD) process. Based on the primary concern of interactive systems design which pursues how the power of interactivity can be utilized and put to work, several interactive design strategies in Web-based systems are recommended through this research.

This paper proposes the physical human-robot interaction method that controls the robot arms using ITO touch panel sensor as the skin of robot. To implement physical human-robot interaction, the method of using the force/torque sensor and the method of using tactile sensor created by arranging small element type of sensor have been studied. However, these sensors have the pros and cons in terms of price and performance. This study aims to demonstrate the economy of element type sensor and the accuracy of force/torque sensor through experiment by proposing the method of physical interaction using the touch panel as the skin of robot, and by constructing overall system. The experiment was carried out for the method of controlling the robot arm by installing end-effecter and the method of controlling robot arm by creating the gesture with reference point on the touch panel. Through this experiment, the possibility of teaching control using the touch panel was confirmed.

This study was designed to empirically analyze the effect of control activities(physical, managerial and technical securities) of information protection on organizational effectiveness and the mediating effects of information application. The result was summarized as follows. First, the effect of control activities(physical, technical and managerial securities) of information protection on organizational effectiveness showed that the physical, technical and managerial security factors have a significant positive effect on the organizational effectiveness(p < .01). Second, the effect of control activities(physical, technical and managerial securities) of information protection on information application showed that the technical and managerial security factors have a significant positive effect on the information application(p < .01). Third, the explanatory power of models, which additionally put the information protection control activities(physical, technical and managerial securities) and the interaction variables of information application to verify how the information protection control activities( physical, technical and managerial security controls) affecting the organizational effectiveness are mediated by the information application, was 50.6%~4.1% additional increase. And the interaction factor(${\beta}$ = .148, p < .01) of physical security and information application, and interaction factor(${\beta}$ = .196, p < .01) of physical security and information application among additionally-put interaction variables, were statistically significant(p < .01), indicating the information application has mediated the relationship between physical security and managerial security factors of control activities, and organizational effectiveness. As for results stated above, it was proven that physical, technical and managerial factors as internal control activities for information protection are main mechanisms affecting the organizational effectiveness very significantly by information application. In information protection control activities, the more all physical, technical and managerial security factors were efficiently well performed, the higher information application, and the more information application was efficiently controlled and mediated, which it was proven that all these three factors are variables for useful information application. It suggested that they have acted as promotion mechanisms showing a very significant result on the internal customer satisfaction of employees, the efficiency of information management and the reduction of risk in the organizational effectiveness for information protection by the mediating or difficulty of proved information application.

In this paper, we attempt to explore consumers' willingness to continuously watch stage performances on virtual reality technology platforms and the mediating role of the psychological contract in it through the integration of service quality theory, thus constructing a continuous viewing model and conducting an empirical analysis through SPSS and AMOS. Through the analysis, we came to the following conclusions: 1. Interaction quality, physical environment quality, and outcome quality have a positive impact on psychological contract; 2. The psychological contract has a positive impact on the willingness to continuously watch; 3. Interaction quality, physical environment quality, and outcome quality positively influence the willingness to continuously watch through psychological contract. Therefore, this model can be used by companies to grasp consumers' perceptions of their own service quality and to formulate specific strategies, and it provides new directions and insights for stage performance companies.

에어로졸의 물리적, 화학적 특성은 주로 입자의 크기 분포와 밀접한 관련이 있다. 따라서 시간에 따른 입자의 크기분포의 변화를 아는 것은 중요한 문제로서, 입자에 작용하는 중력이나, 전기적인 힘, 입자간의 상대속도 등에 의해 입자의 크기분포는 달라질 수가 있다. 이러한 입자간의 상호작용으로 인해 서로 충돌하여 합쳐지는 것으로 이를 응집(Coagulation)이라 한다. (M.M.R. Williams, 1988) (중략)

This study intends to provide strategic implication for enhancing trade show's competitiveness by analyzing its structural relationships among service quality, customer satisfaction and customer loyalty. In order to measure service quality factors influencing customer satisfaction and customer loyalty, the empirical analysis was conducted on three kinds of service quality (physical environment quality, interaction quality, outcome quality). The study results indicated that all of the physical environment quality, interaction quality and outcome quality had positive impacts on customer satisfaction. In relationship between service quality factors and customer loyalty, interaction quality and outcome quality showed positive impacts on customer loyalty, whereas physical environment quality did not. The customer satisfaction turned out to have positive impact on customer loyalty.
