The purpose of this study is to provide empirical and quantitative analysis on user's perceived privacy, security, and user satisfaction when providing visualization information about objects and service provider behaviors that users can not perceive in internet service process. Through previous research, we have examined the importance of privacy and security factors as a key factor to be considered for the characteristics of the Internet of things and the Internet of things. In addition, service blueprint, which is one of the service design methodologies to examine the flow of service usage in providing Internet service of things, was examined. In the flow of things internet service utilization, it is found that the things that are out of the user's cognitive area and the behavior of the service provider take up a large part. Therefore, the hypothesis that the trust of the Internet service security and the satisfaction of the user experience can be improved by providing the security visualization information about the behavior of the object and the invisible service provider in the non-contact aspect of the user and the object. In order to verify the hypothesis, we conducted experiments and questionnaires on the use of virtual objects' internet environment and conducted statistical analysis based on them. As a result, it was analyzed that visual information feedback on non - contact and invisible objects and service provider's behaviors had a positive effect on user's perceived privacy, security, and satisfaction. In addition, we conclude that it can be used as a service design evaluation tool to eliminate psychological anxiety about security and to improve satisfaction in internet service design. We hope that this research will be a great help for the research on application method of service design method in Internet environment of objects.

In order to provide theoretical guidance to research in platform strategy, we build the conceptual framework based on the organizational ecology and analyze symbiotic/competitive relationship between platform entities. Platform owner and service provider (i.e. complementors) make symbiotic relationship, where platform owner provide service provider user-base and platform resources such as marketing tools and platform technology, and service provider provide platform owner services which users utilize. In addition to symbiotic relationships, platform owner has competitive relationship with other platform owners, and service provider builds competitive relationship with other service providers. In these relationships, the strategy of platform owner affects service provider and service provider builds a strategy for their own survival and success. This type of interaction makes competitive dynamics in platform. However, previous platform literature focuses on strategies to enhance network effect from the perspective of platform owner. Thus, there is little attention on interaction among the service providers. Using the framework based on community ecology of organizational ecology, we analyze interaction and strategy between platform owner and service provider in the viewpoint of platform openness strategy and platform pricing strategy. This research contributes to the literature of platform strategy by providing a theoretical framework based on organizational ecology to deeply understand the dynamics of platform.

The QoS management is an agreement of service user and service provider in B3G networks, and service provider must support proper the network service to service users by the agreement facts. The service provider must provide the QoS method to maintain the agreed service, which manages the detail method of system level from policy level. By the agreement of service policy, the service provider can give the QoS to the service customer with the service agreement. Hence, in this paper we propose a QoS mapping method of heterogeneous networks to provide the customer service through the service agreement based on the SLA of B3G networks.

The issue of using information system to ensure competitive power in the market is rising. The outsourcing methods that entrust activities of information system of companies to other expert agencies are increasing as the enterprises make a lot of efforts to put their resources to their heart of business in the process of adopting information system. Recently, ASP (Application Service Provider) as new information technology outsourcing method appears due to development of network technology and spreading of peculating software. ASP defines as a software leasing service which is supplied through networks instead of purchasing application software with high price. For successful implementation of ASP, it is necessary to develop a certification program to ensure safety and reliability of ASP. This paper provides the safe and reliable certification program for ASP. In order to develop it, the critical issues related to service quality and certification of ASP are identified and then evaluation methodology for ASP certification program is proposed. This paper presents application certification as the part of ASP certification program.

In this paper, we propose 'a self - conformance system of convergence security provider' to provide basic data for security and reliability of convergence industrial technology, system and service. It is difficult to evaluate convergence security systems, limited to information and communication service providers, unable to check convergence security items, burden of submission documents, difficulty in measuring convergence security service level and we will summarize product and service-based requirements that can be integrated and systematically measure the level of convergence security and define renewed life cycle-based convergence security information and content security and assurance requirements. On the basis of this, each convergence security company declares conformity with the standard itself without the certification of the certification body, and introduces the provider conformity certification system which can manufacture and sell. This will enable the company to strengthen its competitiveness through timely launch and implementation of products and services and cost reduction.

This study was intended to examine the effect that the quality of service delivered by social commercial companies and service providers and perception towards seriousness of service failure would have on the intention of repurchase and revisit. 10 hypotheses were derived from literature review. excluding the questionnaires that contained many missing values or inconsistent or insincere answers. The results of this study can be summarized from 3 aspects. First, it was found that the quality of service delivered by social commerce companies had a statistically significant effect on social commerce companies' service failure(Hypothesis 1) and social commerce company repurchase intention(Hypothesis 3) in connection with the effect that the quality of service delivered by social commerce companies and service providers would have. The quality of service delivered by service providers was found to have a statistically significant effect on service providers' service failure(Hypothesis 2) and service provider revisit intention(Hypothesis 4). Second, the perception towards seriousness of service failure by social commerce companies and service providers was found to have the following effect: The service failure by social commerce companies(Hypothesis 5) was found to have a statistically significant effect on service provider revisit intention(Hypothesis 8), but did not have a statistically significant effect on social commerce company repurchase intention (Hypothesis 6). The service failure by service providers was found to be statistically significant for service provider revisit intention(Hypothesis 7) and social commerce companies purchase intention(Hypothesis 9). Finally, service provider revisit intention was found to be statistically significant for social commerce company repurchase intention(Hypothesis 10).

We deal with a resource allocation problem for multimedia service discrimination in wireless networks. We assume that a service provider allocates network resources to users who can choose and access one of the discriminated services. To express the rational service selection of users, the utility function of users is devised to reflect both service quality and cost. Regarding the utility function of a service provider, total profit and efficiency of resource usage have been considered. The proposed service discrimination framework is composed of two game models. An outer model is a repeated Stackelberg game between a service provider and a user group, while an inner model is a service selection game among users, which is solved by adopting the Kalai-Smorodinsky bargaining solution. Through simulation experiments, we compare the proposed framework with existing resource allocation methods according to user cost sensitivity. The proposed framework performed better than existing frameworks in terms of total profit and fairness.

As this study aimed to examine which influence the nonverbal communication of service provider has upon service performance in terms of service industry, the specific objectives are as follows. First, it tried to examine into the relationship between the nonverbal communication in the service provider, and the emotional attachment. Nonverbal communication is divided into 4 kinds such as physical language, proxemics, paralanguage, and physical appearance. Second, it aimed to examine the relationship between the customer's attachment to the service provider, and the social competence and trust in the service provider. Third, it tried to examine into the relationship of service provider's social competence and trust with the customer satisfaction and with the switching costs. Additionally, it examined the moderating effect in the service type and the service usage period in terms of the model that was presented in this study. Given examining the verified results in these research hypotheses, those are as follows. First, given seeing the relationship between the nonverbal communication and the emotional attachment, it was represented that the physical language, proxemics, and physical appearance, except paralanguage, have significantly positive(+) influence upon emotional attachment. Second, it was indicated that emotional attachment has significantly positive(+) influence upon the social competence and trust in the service provider. Third, the social competence in the service provider had no positive effect(+) on customer satisfaction, and was having significantly positive(+) influence upon the customer's perceived switching barrier. Fourth, it was represented that the customer satisfaction toward the service provider have significantly positive(+) influence upon the switching barrier. Finally, as a result of having verified whether or not the moderating effect in the service type and the service usage period, it was indicated to be produced the difference depending on the service type in the relationships between the physical language and the emotional attachment, between the paralanguage and the emotional attachment, between the emotional attachment and the trust, and between the trust and the switching barrier. Depending on the service usage period, the difference was represented, respectively, in the relationships between the physical language and the emotional attachment and between the physical appearance and the emotional attachment.

The USIM(universal subscriber identity module)-unlock introducing in July 1, 2008 might be led to a significant change that mobile service provider's dominance is considerably dispersed to the handset manufacturer and distributor. Under USIM-unlock environment, mobile service provider, handset manufacturer, and distributor have to make their decisions on their handset distribution channel strategies: the closed distribution channel strategy or the open distribution channel strategy. The change of distribution channel strategy between members in distribution channel can be understood as a matter of strategy choice, and we have developed a theoretical model and analyzed how to make a decision for the member's optimal distribution strategy based on 3-person game model between members of mobile phone distribution channel, under both of '1 subscriber-1 handset' and '1 subscriber-multiple handset' assumptions. Under '1 subscriber-1 handset' assumption, the closed strategy controlled by mobile service provider is all players' optimal solution because the maximum size of the mobile phone market is limited by subscribers. But, as total expected profit by the handset and distribution subsides is a deficit, mobile service provider have to choose the open strategy and consider the conversion to MNO(mobile network operator). Under '1 subscriber-multiple handset' assumption, mobile service provider is trying to find the way how to lock-in its service and mobile phone and how to maximize ARPU(average revenue per unit), while handset manufacturer and distributor have to look for the way how to maximize the mobile phone market using their own marketing efforts, because it is expected that total mobile handset demand for the open market is bigger than demand for the closed market under '1 subscriber-multiple handset' assumption.
