Our society has long been talking about necessity for innovation. Since companies in particular need to carry out business innovation in their overall processes, they have attempted to apply many innovation factors on sites and become to pay more attention to their innovation. In order to achieve this goal, companies has applied various information technologies (IT) on sites as a means of innovation, and consequently IT have been greatly developed. It is natural for the field of IT to have faced another revolution which is called cloud computing, which is expected to result in innovative changes in software application via the Internet, data storing, the use of devices, and their operations. As a vehicle of innovation, cloud computing is expected to lead the changes and advancement of our society and the business world. Although many scholars have researched on a variety of topics regarding the innovation via IT, few studies have dealt with the issue of could computing as IT. Thus, the purpose of this paper is to set the variables of innovation attributes based on the previous articles as the characteristic variables and clarify how these variables affect "Performance Expectancy" of companies and the intention of using cloud computing. The result from the analysis of data collected in this study is as follows. The study utilized a research model developed on the innovation diffusion theory to identify influences on the adaptation and spreading IT for cloud computing services. Second, this study summarized the characteristics of cloud computing services as a new concept that introduces innovation at its early stage of adaptation for companies. Third, a theoretical model is provided that relates to the future innovation by suggesting variables for innovation characteristics to adopt cloud computing services. Finally, this study identified the factors affecting expectation and the intention to use the cloud computing service for the companies that consider adopting the cloud computing service. As the parameter and dependent variable respectively, the study deploys the independent variables that are aligned with the characteristics of the cloud computing services based on the innovation diffusion model, and utilizes the expectation for performance and Intention to Use based on the UTAUT theory. Independent variables for the research model include Relative Advantage, Complexity, Compatibility, Cost Saving, Trialability, and Observability. In addition, 'Acceptance for Adaptation' is applied as an adjustment variable to verify the influences on the expected performances from the cloud computing service. The validity of the research model was secured by performing factor analysis and reliability analysis. After confirmatory factor analysis is conducted using AMOS 7.0, the 20 hypotheses are verified through the analysis of the structural equation model, accepting 12 hypotheses among 20. For example, Relative Advantage turned out to have the positive effect both on Individual Performance and on Strategic Performance from the verification of hypothesis, while it showed meaningful correlation to affect Intention to Use directly. This indicates that many articles on the diffusion related Relative Advantage as the most important factor to predict the rate to accept innovation. From the viewpoint of the influence on Performance Expectancy among Compatibility and Cost Saving, Compatibility has the positive effect on both Individual Performance and on Strategic Performance, while it showed meaningful correlation with Intention to Use. However, the topic of the cloud computing service has become a strategic issue for adoption in companies, Cost Saving turns out to affect Individual Performance without a significant influence on Intention to Use. This indicates that companies expect practical performances such as time and cost saving and financial improvements through the adoption of the cloud computing service in the environment of the budget squeezing from the global economic crisis from 2008. Likewise, this positively affects the strategic performance in companies. In terms of effects, Trialability is proved to give no effects on Performance Expectancy. This indicates that the participants of the survey are willing to afford the risk from the high uncertainty caused by innovation, because they positively pursue information about new ideas as innovators and early adopter. In addition, they believe it is unnecessary to test the cloud computing service before the adoption, because there are various types of the cloud computing service. However, Observability positively affected both Individual Performance and Strategic Performance. It also showed meaningful correlation with Intention to Use. From the analysis of the direct effects on Intention to Use by innovative characteristics for the cloud computing service except the parameters, the innovative characteristics for the cloud computing service showed the positive influence on Relative Advantage, Compatibility and Observability while Complexity, Cost saving and the likelihood for the attempt did not affect Intention to Use. While the practical verification that was believed to be the most important factor on Performance Expectancy by characteristics for cloud computing service, Relative Advantage, Compatibility and Observability showed significant correlation with the various causes and effect analysis. Cost Saving showed a significant relation with Strategic Performance in companies, which indicates that the cost to build and operate IT is the burden of the management. Thus, the cloud computing service reflected the expectation as an alternative to reduce the investment and operational cost for IT infrastructure due to the recent economic crisis. The cloud computing service is not pervasive in the business world, but it is rapidly spreading all over the world, because of its inherited merits and benefits. Moreover, results of this research regarding the diffusion innovation are more or less different from those of the existing articles. This seems to be caused by the fact that the cloud computing service has a strong innovative factor that results in a new paradigm shift while most IT that are based on the theory of innovation diffusion are limited to companies and organizations. In addition, the participants in this study are believed to play an important role as innovators and early adapters to introduce the cloud computing service and to have competency to afford higher uncertainty for innovation. In conclusion, the introduction of the cloud computing service is a critical issue in the business world.

Performance assessment has been introduced to school education as an alternative measure of the former educational assessment which put much emphasis on the result rather than the process of learning, memorization than pursuit of knowledge, and passive than active study. As for the subject of mathematics, the change of the assessment came to replace multiple choice tests with descriptive- and statement-type tests. This means animprovement on the testing system, focusing on the process of finding out the answer. The main focus, however, is still on the intellectual domain without paying due attention to the emotional domain of mathematics education. The previous studies on the assessment of emotional domain In mathematics have shown that there are stumbling blocks in the application of the assessment, such as the disputes on the reliability, objectivity, and fairness as well as the complicated procedure of applying the results to school records. The lack of the development and supply of the appropriate assessment tools have also been pointed out. Therefore, this study has been carried out with the intention of establishing an applicable standard of assessment on the emotional domain of high school matematics. As a result, detailed standards of performance assessment, which adopt oral examination, discussion, observation, and report have been developed. The problems which are likely to emerge In the course of the application of the newly developed assessment are under study as a continuing research project.

Kung fu films stand out among many types of films and are sought after by a large number of loyal audiences. In order to explore the mystery, we use the theory of uses and gratifications theory to study kung fu films in order to explore the audience's viewing needs of kung fu films In the existing research, most scholars adopt qualitative research and Chinese culture contained in kung fu movies. Few people use quantitative research, and this area of research is almost blank. Therefore, we conducted a quantitative research on kung fu films based on the methodology of uses and gratifications. The questions revolve around: Can kung fu movies meet audiences' needs? What is the purpose of watching a kung fu movie? After analysis with SPSS, interesting results emerged. In the regression analysis, we found that the psychological need for compensation has a positive impact on Viewing satisfaction, while the social need has a significant negative impact on viewing intention. At the end of the article, we also put forward my own solutions. We also hope to provide better suggestions for the development of Chinese kung fu films through my research, so as to make kung fu films more perfect.

Outbreaks of health risks such as the Influenza A virus (H1N1) are continuing, which highlights the immediacy of risk control strategies to reduce public's fear and protect the safety of the society. Evidence suggests that success for risk management is basically dependent on the public's willingness to adopt health behaviors recommended by experts, and the behavioral intention relies on their risk perception. Understanding of how individuals think of and feel about health risks is thereby important. This article aims to provide insights for future study on health-risk perception. The main streams and recent developments of theorizing and research on health risk perception are reviewed. The issues, such as (1) health risk perception is an important component for shaping relevant health policies as it reflects public trust of the institutions managing health risks, (2) despite this significance, however, few attempts have been made to address the meaning of 'perceiving health risks' in health services research, are shed light on. On the basis on the critical discussion of the contributions and the limitations of the literature, this article finishes with a few of research agendas by three levels of analysis in risk perception research.

The rapid change of consumer expectations in shopping environments has required retailers to actively adopt omni-channel services, however, limited research exists on the topic. We identify the effect of consumer's utilitarian shopping value on expectations for omni-channel services. An online survey was conducted on 176 subjects who had experience using omni-channel services. We employed Unified Theory of Acceptance and Use of Technology (UTAUT) as our theoretical model to explore the mechanisms of consumers' acceptance of omni-channel services in fashion. We used SPSS ver. 22.0 and AMOS ver. 22.0 programs to analyze data. The results indicate that utilitarian shopping value has a positive effect on performance expectancy, effort expectancy, and social influence for omni-channel services. Performance expectancy for omni-channel services also has a positive effect on the purchase intentions of fashion products. Effort expectancy for omni-channel services also positively increases the purchase intentions of fashion products. Last, the social effect of omni-channel services has a significant positive effect on purchase intention. All the hypotheses were supported. The research findings can provide the fashion distribution industry with useful basic data to understand the needs of consumers who use multi-channels when establishing a new channel or marketing strategy.

Radio Frequency Identification(RFID) is rapidly growing the attention of many firms as a care technology for their businesses. As RFID moves into the mainstream, it replaces the standard barcodes that is used to identify and track products for a long time. With the intention of gaining competitive advantages, some firms have started the changeover to RFID technology while others have been disinclined to adopt it. Thus, this study examines firms as an attempt to identify key organizational characteristics driving the ear1y adoption and successful implementation of RFID. Results from 228 adopting organizations show Organizational Needs(Ubiquity and Performance Gaps), Technological Factors(Perceived Benefits and Perceived Cost Savings) and RFID Reduced Risk have a significant influence on RFID initiation. In addition, Trust Factors(Institutional Trusts and Inter-organizational Trusts) have a significant impact on RFID Reduced Risk. Finally, Organizational Readiness(Financial Resources and Technological Knowledge) have a significant influence as moderating effects between RFID initiation and adoption. The implications of the findings propose a new theoretical framework for the future IT/IS adoption study and offer suggestions for RFID researchers and practitioners in the development of the technology.

Generally, higher brand equity ends up with higher market share and higher profitability. However, superior brand equity does not guarantee the success in the market. That is, consumer choice is closely related to brand equity but we need more than brand equity to explain this complex phenomenon. We adopt the customer equity concepts: value equity, brand equity, and retention equity. By incorporating value equity and retention equity into customer equity, it is possible to avoid the problems of using the brand equity only. In the paper, we apply this customer equity concepts to cellular phone and investigate the effects of antecedent variables such as exposure, knowledge, positive experience and negative experience on the components of customer equity. In addition, as surrogate measure of customer lifetime value, the weighted measure of purchase intention, consideration set inclusion, and next purchase is used as dependent variable. We estimate the effects of components of customer equity at the brand level and aggregate level using SURE model. Estimation results show that Apple has currently low market share but has high future potentials and Korean firms have currently high market share but has rather low future potentials.

This study proposes a new conceptual Hybrid Electric Brake System (HEBS) which overcomes problems of a conventional hydraulic brake system. HEBS adopt a contactless type bake system when a vehicle speed is high, to obtain superior braking performances by eddy current. On the contrary, when a vehicle speed is low, HEBS employs a contact type brake system such as conventional hydraulic brake system to generate higher brake force. Therefore, HEBS transfers faster the braking intention of drivers and guarantees the safety of drivers. Braking torque analysis is performed by using a mathematical model which is proposed to investigate the characteristic of a vehicle dynamics when the brake torque is applied. Optimal torque control is achieved by maintaining a desired slip corresponding to the road condition. The results show that HEBS reduces the stopping distance, saves the electric energy, and increases the stability.
