The purposes of this paper are to investigate the impact of managers' agency problem on asymmetrical behavior of SG&C and to examines whether or not the corporate governance mechanisms can have any moderating effects on Asymmetrical behavior of SG&C. To test empirically the above mentioned purposes, we gathered firm-year data of manufacturing firms from 2007 to 2012 and the sample firms are listed on the Korean Stock Exchange. The findings of this research are summarized as follows: Firstly, for those firms whose agency problems are high, the stickiness of SG&A increases as sales variation. The results imply that managers are not willing to reduce their perquisite consumption in proportion with sales reduction. Secondly, we investigate how corporate governance mechanisms influence the cost stickiness behaviors of SG&A for those firms whose agency problem are high(above the median value of free cash flow used as a proxy of agency problem). The results are that as the effectiveness of corporate governance mechanisms improve the cost stickiness of SG&A mitigation except for the insider ownership. These results show that agency problem has impact on the asymmetrical behavior of SG&A. And effective governance mechanisms have moderate effects on the reducing stickiness behavior of SG&A caused by agency problem.

This research focuses on the perceived marketplace influence(PMI: A belief that recognizes the effect that an individual's actions will have on the behavior of other consumers in the market and thus drives them to act on fair trade consumption) of consumers who may act as a more fundamental explanatory alternative to the gap in attitudes and behaviors of fair trade products. The purpose of this study is to investigate the relationship between consumer's self - determination psychological needs (autonomy, competence, relevance), influence (personal influence, market influence), and the assets of fair trade products. As a result of the empirical analysis, it was found that among the major psychological needs related to self-determination, the variables other than competence and the perceived influence relations of consumers can be directly formed, and the perceived consumer effectiveness(PCE) has a positive influence on perceived marketplace influence(PMI). It is also found that the perceived influence of consumers(PCE, PMI) has an influence on the consumers' perceived equity of Fair Trade products. The results of this study will provide an opportunity to theoretically explain the gap between consumers' attitudes and behaviors of Fair Trade products, which is a part of ethical consumption, and provide important implications for the establishment of marketing strategies.

Customers are not merely responders but rather active value creators. As a result most researches related to customer value creation behavior focus on customer participation behavior and interaction between service provider and customer. This study set the research model to examine the correlation between customer to customer interaction, brand attachment and customer value creation behavior. For this study, the relationship among social support, C-to-C social interaction, similarity, brand attachment, and customer value creation behavior were modelled and used to validate our hypotheses. A path model was verified with structural equation modeling using dataset from survey. Results of this study are summarized as follows. First, this study show the C-to-C social interaction, such as social support, C-to-C social interaction, similarity have effects on brand attachment. Thus, this was statistically significant although dismissed from hypothesis verification. Second, the structural correlation shows brand attachment has positive effect on customer value creation behavior The findings suggest that managers need to identify and pay attention to positive customer to customer interaction in the service encounter so that it influence customer brand attachment and customer value creation behavior which is the competitive advantages of service brand.

Cloud Computing has drawn attention as one of 10 IT strategic technology trends and has various advantages such as cost reduction and enhancing business flexibility. However, corporations hesitate to adopt the service because of unexpected risks. Especially compared to large firm, medium and small ones use public cloud that security risk is high. Meanwhile, real option strategy has drawn attention as the method to hedge uncertainty in IT projects. Therefore, in this study causal relationships among technical, security, relational, and economic risks of cloud service will be investigated. Eventually, this study investigates how those risks influence the intention to choose the real option about the cloud service. For this study, five hypotheses is drawn, and a survey is conducted about the medium and small firms which are currently using cloud service to examine hypotheses. Since the study is at organizational level, 287 questionnaire replies are recalculated to 120 firms. For statistical analysis, Smart PLS and SPSS Statistics18 are used. As a result, technical risk of cloud service has significantly positive influence on security risk. Second, security risk and relational risk of cloud service has significantly positive influence on economic risk. Third, economic risk of cloud service has significantly positive influence on the intention to purchase the delay option or abandon option. Based on this result, this research discussed practical and academic implications and the limitations.

IT project is a knowledge-based project with high uncertainty in role assignment and task allocationamong team members. This study empirically investigate steam members' interactive behavior in IT projects based on the framework of social interdependence theory. The goal and task interdependencebetween team members were posited as antecedents of project performance with communication effectiveness and knowledge sharing as mediating variables. To test the research model, a dataset was collected form IT and business professional pairs of 123 IT project teams. The results indicated that the theory of social interdependence is applicable to explaining the promotive interaction in IT project teams. In detail, task interdependence appears to have influence on both promotive interactions (communication effectiveness and knowledge sharing), and goal interdependence influences only on communication effectiveness. Knowledge sharing is found to be a significant mediator between social interdependence and project performance. However, communication effectiveness only indirectly influences project performance via knowledge sharing. Academic and practical implications are discussed.

This research uses the Analytical Hiararchy Process (AHP) to scientifically and systematically calculate the weightings of attributes as well as dimensions considered for assessing an informational website. The present paper aims at observing and using the computed weightings to comparatively examine the perceptions of customer users and business users. We use the 3C-D-T (i.e., Content, Community, Commerce, Design, and Technology) framework to conduct a case study where we review and assess restaurant websites and calculate attribute weightings on these websites. Data used for website review was collected in two phases. Data in the first phase was collected from customer users, and data in the second phase was from business users who had registered in the same websites. Users were instructed to perform a pairwise comparison of the relative importance of website attributes. Our data analysis revealed that the customer users and business users demonstrated different views on the relative importance of the individual attributes. Based on the findings, we suggested that business users of restaurants should adapt their views to the customers' views to minimize perceptional differences, thereby increasing customer satisfaction and accomplishing successful business outcomes.

Purpose: The purpose of this study is to prepare a more efficient operation alternative for both systems by comparing and analyzing the recently introduced COOP(Continutiry of Operation Plan) and existing NIPP(National Infrastructure Protection Plan). Method: The basic data of the two systems were collected for research and compared and analyzed by dividing them into the content and procedural aspects. In addition, The efficient operation alternative were derived for experts in the disaster area by utilizing AHP. Result: The National Infrastructure Protection Plan(NIPP) and the Continuity of Operation Plan(COOP) were found to be very similar in terms of content and procedures, and the AHP survey also found that integrating the two schemes was a more efficient and effective operation method. Conclusion: As the recently introduced the Continuity of Operation Plan(COOP) has a wider area of activity than the National Infrastructure Protection Plan(NIPP), and has a continuous management system structure with a more precise workframe, A more efficient national safety net will be realized by reorganizing and integrating it into a more enhanced the Continuity of Operation Plan(COOP) through readjustment of relevant laws and regulations.

With the widespread adoption of mobile devices, such as smart phones and smart pads, as well as the rapid growth of mobile technologies, consumer shopping patterns are changing. This study investigates key factors of consumer purchasing intention in a mobile shopping mall context by incorporating trust belief into the theory of planned behavior. We posit perceived usefulness, perceived enjoyment, perceived ease of use, and trust belief as antecedents of behavioral attitude toward mobile shopping malls. Moreover, social influence and security are identified as key enablers of trust belief on mobile shopping malls. Data collected from 154 consumers with purchasing experience in mobile shopping malls are empirically tested against a research model using partial least squares. Analysis results show that behavioral attitude and perceived behavioral control significantly influence purchasing intention. Moreover, this study reveals the significant effects of perceived usefulness and perceived enjoyment on behavioral attitude. Trust belief indirectly influences purchasing intention through behavioral attitude and is significantly affected by social influence. Understanding consumer purchasing decision-making processes in mobile shopping malls can help service providers to develop effective marketing and operation strategies and campaigns.

Large-scale distributed applications based on Internet and client/server applications have to deal with series of problems. Load balancing, unpredictable communication delays, and networking failures can be the example of the series of problems. Therefore. sophisticated applications such as teleconferencing, video-on-demand, and concurrent software engineering require an abstracted group communication, CORBA does not address these paradigms adequately. It mainly deals with point-to-point communication and does not support the development of reliable applications that include predictable behavior in distributed systems. In this paper, we present our design, implementation and performance analysis of the group communication using the CORBA-ORB. JAVA-RML and Socket based on distributed computing Performance analysis will be estimated latency-lime according to object increment, in case of group communication using ORB of CORBA the average is 14.5172msec, in case of group communication using RMI of Java the average is 21.4085msec, in case of group communication using socket the average is becoming 18.0714msec. Each group communication using multicast and UDP can be estimated 0.2735msec and 0.2157msec. The performance of the CORBA-ORB group communication is increased because of the increased object by the result of this research. This study can be applied to the fault-tolerant client/server system, group-ware. text retrieval system, and financial information systems.
