PKI(Public Key Infrastructure)-based information certification technology has some limitations to be universally applied to mobile banking services, using smart phones, since PKI is dependent on the specific kind of web browser, Internet Explorer. OTP(One Time Password) is considered to be a substitute or complementary service of PKI, but it still shows low acceptance rate. Therefore, in this research, we analyze why OTP has not been very popular, and provide useful implications of making OTP more extensively and frequently used in the mobile environment. Perceived security of OTP was set as a higher-order construct of integrity, confidentiality, authentication, and non-repudiation. Research findings show that security awareness and perceived security of OTP is positively associated, and the relationship between perceived security and trust on OTP is statistically significant. Also, trust is positively related to intention to use OTP continuously.

The purpose of this study is to analyze the regionality of RCR Arquitectes's architectural characteristics and to figure out how these characteristics were applied to each project. The reason why they become world-class architects, who recently awarded Pritzker Architecture Prize, is because they deal with universality as their most previous inspiration which is harmonized with their own experience of hometown, Olot. They pursue "Equilibrium" is their fundamental aspect which is inspired by their experiences in Olot. The concept "Equilibrium" is classified into three main points. First, the close relationship between the landscape and architecture is priority in this concept, which is the potential of the place through architecture to form a new landscape and to pursue a balance with nature. In order to keep the relationship closer, they captured the intuitive idea through the watercolor sketch in the beginning of the project. And they also promoted the involvement of surrounding nature through horizontality, frame and void, etc. Secondly, they used cor-ten steel as the main material for most projects, and the symbiotic relationship with nature that allow people to have a different sensory experience. And the last feature is that their buildings are easily applied to different usage through users intend and behave so their buildings have transformed with various values. It is because they design buildings with strategy to harmonize between landscape and environment so they have various expansion as buildings or objects. The present era of globalization, architecture with regional identity plays an important role in conveying the values of each region. The purpose of this study is to investigate about RCR Arquitectes, who informed about the Olot and Spain's regionality, and to consider the development of architecture that implies our country's identity.

This study empirically examines the effects of regulation on online gaming. Going beyond ad hoc heuristic approaches on individual behavior, we investigate the effects of regulation on dynamic changes of games or service providers. In particular, we propose three theoretical perspectives: social influence to investigate the regulation effect, the role of prior experience to determine the difference in the regulation effect size through users' prior experience, and network externalities to discover the difference in the regulation effect size according to the number of users on an online gaming platform. We use the vector autoregression methodology to model patterns of the co-movement of online games and to forecast game usage. We find that online gamers are heterogeneous. Therefore, policy makers should make suitable regulations for each heterogeneous group to effectively avoid generating gaming addicts without interrupting the economic growth of the online gaming industry.

The aim of this study was to identify the relationship between smartphone usage time and oral health among Korean adolescents using data from the 13th (2017) Korea Youth Health Behavior Survey, which included 62,276 subjects. The daily smartphone usage time was categorized as not used, less than 2 hours, more than 2 hours, less than 4 hours, and more than 4 hours. Our results reveal that 60.1% of participants and 61.7% of smartphone users experienced oral disease symptoms annually, 27.4% of total adolescents used smartphone more than 4 hours daily during weekdays, and 53.8% more than 4 hours daily on weekends. The results from multivariate logistic regression analysis adjusting general characteristics show that the adjusted odds ratio (aOR) for risk of oral disease experience was 1.78 (95% confidence interval, CI 1.67-1.91) times higher in the group that used smartphones more than 4 hours a day on weekdays and 1.81 (95% CI 1.70-1.93) times higher in the group that used smartphones more than 4 hours a day on weekends compared to the group that did not use smartphones. The results indicate that smartphone overuse among Korean adolescents has a harmful effect on oral health. Education programs for reducing excessive use of smartphones among adolescents will help promote oral health.
