Internet Protocol Television (IPTV) provides an interactive and personalized service for realizing integrated broadcasting and telecommunication services. Set-top box (SIB) connected to TV is an essential component required for IPTV and has a unique hardware identifier used in identification and authentication. It means that subscriber authentication based on box-level identification is inconsistent with IPTV's main intention of providing personalized services. The proposed solution is to provide an opportunity to use the flexible user-centric authentication mechanism through Java Card applets in IPTV application server and 3G networks. This paper suggests personalized services by moving the user's private data and authentication management beyond the STB to a truly personalized device, the ubiquitous mobile phone. In addition, this paper presents effectiveness and security analysis for verifying the proposal.

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.

Since 2008, large-scale personal information breach incidents have occurred frequently. Even though national education, policy, and laws have been enacted and implemented to resolve the issue, personal information breaches still occur. Currently, individuals cannot confirm detailed information about what personal information has been affected, and they cannot respond to the breaches. Therefore, it is desirable to develop various methods for preventing and responding to personal information infringement caused by breach and leakage incidents and move to privacy protection behaviors. The purpose of this study is to create understanding of personal information security and information breach, to present services that can prevent breaches of personal information, to investigate the necessity of and analyze the potential public demand for such services, and to provide direction for future privacy-related information services.

Conventional studies on technology acceptance have focused on information technology for utilitarian value and hence based on 'theory of reasoned action'. Correspondingly, the studies depend on perceived usefulness and perceived ease of use as rational decision making elements. However, in ubiquitous society, innovative technologies are applied to non-task area, as well as task-oriented area. Therefore, users are more influenced by affective factors than cognitive factors in causing their usage intention. In line with those discussions, we cannot make sure that the conventional technology acceptance model could fully explain the current u-service acceptance phenomenon. Hence, to overcome the limitations of the prior technology acceptance studies, we propose an amended TAM which includes one hedonic factor and two factors on ubiquitous computing technology : ubiquity and intelligence.

As the growth rate of IPTV VOD usage increases it is necessary to analyze VOD usage patterns systematically. This study divides VOD users into free VOD and paid VOD users, then explores how VOD usage motivations, usage patterns, and demographic factors affect the differences between two groups. The results show that social motivation, VOD satisfaction, using content after the holdback expiration, an intention to pay for ad-skip, the proportion of VOD usage, a VOD give-up experience, TV usage time, and SVOD usage time, are statistically significant. Except the VOD satisfaction factor, all of the factors analyzed are more likely to expect paid VOD users. Additionally this study found paid VOD users are more likely to use a SVOD service as an alternative one compared with free VOD users.

Objectives The aim of this study is to identify the satisfaction of Korean medicine treatment by traffic accident. Methods This study was carried out 103 cases of traffic accident patients which had been treatment in Dongshin university Korean medicine hospital and Chung-Yeon Korean medicine hospital from June, 2014 to September, 2014. The survey used by preceding articles was accepted for assessment of the satisfaction degree of patients in this study. All data were coded by SPSS v18.0 and analyzed by descriptive maneuver, x2-test, T-test and correlation. Results According to the survey, 93.2% of patients included this study were hospitalized in the Korean medical hospital within 2 weeks from TA and 90.3% were satisfied with the current medical service. The answer that Korean medicine is superior to western medicine for TA treatment was the main reason for selecting Korean medical hospital. 46.6% of patients satisfied Acupuncture treatment and 29.1% of patients satisfied Korean physical treatment. There were no differences in the satisfaction degree with sex, age, education and occupation. The satisfaction degree of the current Korean medical service was significantly correlated with doctor's service, use the procedure and reuse intention. Conclusions We could see that the satisfaction of Korean medicine treatment is relatively high. The continuous and repetitive research is needed in order to improve the quality of Korean medicine hospital service and the satisfaction of patients by traffic accident.

The South Korean Ministry of Land, Infrastructure, and Transport designated seven automated driving test beds required to evaluate vehicle performance every year for the expansion of mobility services based on automated driving. As a fundamental study, we suggested a necessary example of evaluating the performance with a satisfaction survey for the services before the evaluation. First, we surveyed the perception of automated driving services of users and the public in Sejong-si, South Korea. The survey showed that the users had a higher level of awareness of automated driving technology and intention to use it than the public. Second, the satisfaction survey was conducted on demand-responsive public transportation and automated driving service users. Notably, using the Wilcoxon Rank Sum Test, among the non-parametric statistical analysis methods, we found that safety-related factors affected the overall satisfaction of users of automated driving services. On the other hand, in the case of the demand-responsive public transportation service users, factors related to service convenience affected overall satisfaction. Hence, the results of these surveys are expected to be used as basic data and guidelines to improve the quality of automated driving services and policy establishment.

The purpose was to contribute substantially in terms of marketing strategic planning and implementation of coffee shops. Additionally, the target was set as the favorite coffee shops on the basis of the young people. Through the IPA Matrix, subdividion variable was derived and by using the variables in each quadrant, tested the variables that have significant effect on satisfaction, reuse, and recommendation intentions. The study results showed that there was a significant difference in the importance performance (IPA) difference analysis of coffee shop service quality elements and this proved that empirically, the expectations were different. Additionally, it was evident that there were statistically significant and not statistically significant elements in the relationship between service quality element and the overall satisfaction rate in each elements shown in the IPA. Through this, it was possible to provide the information on what service quality elements to focus and distribute. It was possible to understand that the ultimate goal should be satisfaction since the overall satisfaction positively affects the reuse and intention of recommendation and it was possible to re-confirm the previous studies which stated that overall satisfaction, reuse, and recommendation intentions have a positive influence.

Virtual communities have been suggested to play important roles such as attracting customers, building customer loyalty, and leading to commercial transactions. Little research in marketing has focused on virtual communities in spite of its importance indicated by many practitioners and conceptual studies. More specifically, little research has empirically examined factors of customer participation and its consequences. This research investigate if customers' participation motives in virtual communities affect their sense of community and if sense of community affects customers' loyalty towards and purchase intentions from the website offering the community service. One hundred ninety six questionnaires were collected from individuals who have participated in and have been involved in online activities in various virtual communities. Major results of this research can be summarized as follows. First, participation motives employed significantly affected customers' sense of community and more specifically, perceived ease of use and perceived playfulness had a large influence on the customers' sense of community. Second, customers' sense of community positively affected their loyalty toward the community and more specifically, membership and emotional connection had a large influence on loyalty. Third, customers' sense of community did not affect directly their purchase intentions. Fourth, customers' loyalty toward virtual communities had a significant, positive, although marginal, influence on their purchase intentions.
