The purpose of this study was to find about personal information security of internet and social networks by focusing on end users. User competence and subjective criterion, which are the antecedents, are affecting security behaviors For these security behaviors, the study examined the relationship between security behavior intention on internet use and security behavior intention about social network that is actively achieved in many fields. Behaviors of internet and social network were classified into an action of executing security and an action of using a security technology. In addition, this study investigated a theory about motivational factors of personal intention on a certain behavior based on theory of reasoned action in order to achieve the purpose of this study. A survey was conducted on 224 general individual users through online and offline, and the collected data was analyzed with SPSS 12.0 and SmartPLS 2.0 to verify demographic characteristics of respondents, exploratory factor analysis, and suitability of a study model. Interesting results were shown that security behavior intention of social network is not significant in all security behavior execution, which is security performance behavior, and security technology use. Internet security behavior is significant to security technology use but it does not have an effect on behavior execution.

LBS(Location-Based Service) is one of the smartphone application services which has been receiving great attention recently. Various applications of smartphone use LBS to provide innovative services. However, use of LBS raises privacy concerns because the location information of users is constantly exposed. Privacy calculus perspective attempts to understand the characteristics of the user's privacy. It is based on the risk-benefit analysis in the economics' perspective. That is, when the benefit expected through personal information disclosure is higher than risk, we are willing to provide personal information. This research suggested a research model based on the privacy calculus perspective to clarify the effect of information disclosure intention of smartphone LBS application users. Based on the main factors of privacy calculus, perception of privacy risk and privacy benefit, the relationship of the perceived value and the information disclosure intention was empirically analyzed by utilizing structural equation modeling(SEM) methodology. According to the results of the empirical analysis, it was found that all relations have statistically significant explanatory power except the relation between privacy concern and information disclosure intention. This study showed a strong evidence of antecedent factors based on privacy calculus of personal information disclosure in smartphone LBS applications.

This study explores the factors influencing user satisfaction of mobile IPTV and their relationship. We formulate the research model based on characteristics of mobile device and IPTV. Responsiveness, contents satisfaction, price satisfaction, aesthetic simplicity, network quality are proposed as essential antecedents of mobile IPTV satisfaction. We also suggest network quality and gender as moderators. Our data analysis with 297 mobile IPTV users shows contents and price have significant positive effect on mobile IPTV satisfaction. Network quality shows positive moderation effect on the relationship between responsiveness and satisfaction.
A Comparison on the Factors Influencing Customer Values in Electronic Commerce between Korea and China
Lee, Hyun-Kyu ; Han, Jae-Ho ;

Means-Ends Network model was used to identify factors of means objective(means supplied by vendor) and fundamental objectives(purchasing motivations) for purchasing decision-making structure and dimensions of customer values on purchasers of internet shopping mall in Korea and China. In Means-Ends Network 6 factors(shopping travel, shipping assurance, vendor trust, online payment, product choice, and recommender systems) were found as a means objectives and 3 factors(shopping convenience, internet environment, customer support) as a fundamental objectives of shopping. However the results of hypotheses test for Means-Ends Network show some important differences between two countries. Something important to notice here is that Chinese customers shopping in China recognize shipping assurance factor and vendor trust factor as important factors satisfying all fundamental objectives unlike as in the case of our country. As these two factors are attribution factors responsible to the sellers, it is identified that customers do not trust the sellers and sellers have not met the expectations of customers. Therefore, these results show that the seller efforts assuring the reliability of the seller themselves, such as conducting its own compensation scheme are more important rather than the establishment of the guarantee institution to guarantee reliability and delivery assurance of sellers and implementation of legal and institutional apparatus such as the settlement of e-commerce licence system. Though this study presents such an important marketing implications, it can be pointed out that the limits are this research was done on the general Internet shopping malls without considering the Internet shopping mall types of diversity, the survey was designed around the student samples for convenience of the investigation because it was an international survey and the collected data has been limited to the western coast cities, such as China's Beijing, Shanghai, and Dalian.

The most of international shipping cargoes are transported by ship and the shipping market has been continuously increasing. However, due to the recent global recession, the volume of trade decreased accordingly, and the competition between shippers to gain a competitive advantage in the shipping market continues deepening. To do this, researches on transportation costs savings as well as ways to improve customer service are needed and recently related researches are being pursued. Car carriers which transport more than 80% of car import and export volume in the world also make a lot of effort in order to reduce transportation costs, but in contrast related researches are seldom fulfilled. In this study, we developed an agent system that supports the efficient transportation of car carriers plan so that the car carriers can increase competitiveness through reduction of the logistics costs. To make this, we researched an algorithm for maritime transportation planning, and also developed a prototype of an agent system which can collect the necessary information in real time and establish a dynamic plan.
