The purpose of this study is to investigate the research model attempting to explain factors influencing consumers' attitude towards Smartphone adoption and behavioral intention to use a Smartphone. The 357 sets of data are tested against the model using SEM (structural equation model). The research results reveal that organizational and social influences, consumers' self-actualization, and trust affect consumers' attitude towards Smartphone adoption, and behavioral control influences behavioral intention. Implications of the findings suggest that Smartphone should be approached with a holistic view, suggesting that Smartphone research should emphasize Smartphone as a convergent device including both hardware and software with services and applications. Research results are discussed, and limitations of the current study and future research are presented.

Purpose This study reviews technology acceptance research in the information system area and consumer behavior research in the marketing area, sets characteristics of convergence products, personality of consumers and communication channels as main concepts and demonstrates their effects on 'relative level of attraction' and 'intent to adoption. Design/methodology/approach The survey was conducted against potential consumers who have the intent to purchase electric communication media products that provides a variety of functions and service, such as a smart TV, a tablet PC and a smart watch. All items were adapted from previous literature and revised as appropriate the purpose of this study and measured on a 7-point Likert scale with answer choices ranging from "strongly disagree" (1) to (7) "strongly agree." Totally, 300 respondents participated in the survey. Out of the 276 respondents, incomplete or invalid 24 were discarded. With them, SPSS 18.0 and AMOS 20.0 for structural equation modeling were used for the analysis. Findings Main findings are as followed;- First, it is found that 'interrelationship of technology' and 'functional diversification' of convergence products has positive effects on relative level of attraction. Second, perceived behavior control has significant effects on the intent to adoption convergence products. Third, communication through mass media has positive effects on making potential consumers feel attraction about products while there is no relationship with the intent to a. On the other hands, it is demonstrated that there is no relationship influential relationship between communication through interpersonal channels and relative level of attraction while communication through interpersonal channels has significant effects on the intent to adoption.

Background: It has been proven that an individuals health behavior is determined through a series of processes. This study aimed to assess the stages of adoption of breast cancer screening, and to identify the factors relating to progress through these stages. Materials and Methods: There were 202 female participants aged 20-59 years who were living in Chungbuk, South Korea. They were informed of the study purpose and agreed to participate. Data were collected from October 2010 to January 2011 by assessing the breast cancer screening stage, health beliefs, socio-demographic factors, and other facilitating factors. The participant current stage of adoption of breast cancer screening was classified using the Precaution Adoption Process Model (PAPM), and the various PAPM stages were compared with each other to identify factors likely to determine progress between stages. The data were analyzed using the ${\chi}^2$-test, ANOVA, Duncan test, and multiple logistic regression. Results: Approximately half of all participants were not on-schedule for breast self-examination and mammography (unaware, 9.4% and 11.4%, unengaged, 8.4% and 5.0%, undecided, 20.3% and 17.8%, decided not to act, 1.5% and 1.0%, decided to act, 13.4% and 15.3%, respectively). The factors likely to determine the progress from one stage to another were age, marital status, exposure to media information about breast cancer, self-efficacy, and perceived severity. Conclusions: These results suggest that it is necessary to develop a tailored message for breast cancer screening behavior.

Objectives: The aim of this study was to determine the distribution of stages of adoption in stomach cancer screening and elucidate differences among stages. Methods: A randomly selected sample of 712 Korean males and females aged 40 years or over were interviewed. Stomach cancer screening intention and behavior, sociodemographic characteristics, beliefs, self-efficacy and reinforcing characteristics were assessed. Results: The majority of participants were not on-schedule screening(unaware 3.2%, unengaged 20.8%, deciding about acting 24.0%, decided not to act 9.6%, decided to act 14.5%, acting 9.7%, maintenance 18.3%). Perceived susceptibility, perceived barriers, self-efficacy, other cancer screening experiences were significantly associated with higher compared to lower Precaution Adoption Process Model(PAPM) stages. Conclusions: This study appears to be applicable of the Precaution Adoption Process Model to understanding stomach cancer screening behavior. Our results suggest that it is needed to develop the tailored message for adherence of stomach cancer screening.

The global recession circumstances, cloud computing has emerged as a new paradigm in the business IT sector. This paper focuses on Software as a Service (SaaS) among cloud services. The Technology Acceptance Model (TAM) has been popularly utilized for examining how users come to accept a new technology, but have not yet been employed to handle issues regarding SaaS adoption. This paper aims at developing an exploratory model that examines important factors affecting SaaS adoption of small and medium sized companies. The proposed exploratory model tests a number of hypotheses which integrate TAM related theories with additional imperative constructs such as marketing effort. Thus, the findings of this study can not only help company users gain insights into SaaS adoption, but also help SaaS providers obtain inspiration in their efforts to discover more effective courses of action for developing their service and improving marketing strategy.

This study examines the effect of the liability limitation provision (LLP) adoption on firm's cost behavior. In April 2011, Korea introduced the LLP with the purpose of improving the management efficiency by mitigating the risks caused by the manager's failure to make decisions related to business operation. However, there are concerns that the adoption of LLP may lead the manager's moral hazard, so the need for empirical research to verify the effect of the LLP adoption is emphasized. In this study, we analyze the effect of the LLP adoption empirically, focusing on the cost behavior that is affected by the manager's decision making. From the empirical result, we find that LLP adopted companies have strengthened the cost stickiness of selling, general, and administrative costs rather than non-adopted companies. This suggests that the manager of LLP adopted company makes a more active decision to consider adjusting costs in order to prepare for future recovery in sales when sales is reduced. This study presents empirical evidence to prove the policy validity of the adoption of LLP, and we expect that our results can contribute to the capital market and academia.

Contemporary smartphone competition is generally described as the battle between Apple's proprietary platform and Google's open platform. However, this competition is not limited within smartphone adoption itself. User's pre-adoption of one mobile platform via smartphone can be connected to the post-adoption of the same mobile platform based on the other smart devices (e.g. smart pad). In this study, we investigate whether user's preference to a certain platform is persistent over mobile ecology, from the pre-adoption of one smart device to the post-adoption of following devices. For this investigation, we adopt the dual-model as the ground theory, where post-adoption of IT product is explained by both dedication and constraint factors. The empirical testing first evidences that dual model works well as our research model for identifying the reasons of post-adoption. Next, we group our data into two parts in order to compare the switching behavior of iPhone users and Android phone users. iPhone users show much lower switching rate to Android based smart pads, while Android phone users show higher churn rate to iPad (49.3% : 96.3%). Especially, satisfaction showed much stronger effect than switching cost on the continuing intention of existing platform, when the analysis is given to the iPhone user's group. From this result, we can conjecture the relatively stronger loyalty of iPhone users. More managerial implications on the mobile platform strategy are driven.

As sustainability has grown into a key global issue, more and more information technology (IT) products have adopted these concepts to attract consumers. However, these products potentially require consumers' physical or economic sacrifice at least for a short period of time. Therefore, the reason of consumers' adoption of sustainable IT products cannot be fully explained by the two traditional values: hedonic and utility values. However, expectancy-value theory, which has been used to explain the relationship between value and behavior, still takes hedonic value and utility value into consideration. The purpose of this study is to suggest an amended expectancy-value theory to better explain the adoption of IT products that consider sustainability. For this purpose, two social values-the normative value based on the Schwartz's model of moral norm and the eudemonic value of the Stoic philosophy-were added to the individual values to examine which value particularly influences the adoption of sustainable IT products. In addition, the moderating effect of perceived sustainability between four values and adoption of sustainable IT products was verified.

Despite their various similarities, Seoul's' Gangnam and Seocho districts showed different patterns in the adoption of the RFID household-based waste charging system. Gangnam, one of the 25 wealthiest districts in Seoul, first adopted the RFID system in 2012, but decided abandon it a year later due to inconvenience, sanitation, budget limitations, and management related issues. Unlike Gangnam, Seocho, a largely similar district to Gangnam, started to implement the RFID system in 2015 and successfully adopted this innovation. In this paper, we explain the adoption behaviors of these two districts using a Technology Hype Curve Model with 5 stages. Unlike traditional technology adoption theory, the Hype Curve Model concentrates on the big chasm between early majorities and late majorities, which is a core reason for discontinuity in innovation diffusion. Based on our case study result, the early majority easily gave up adoption due to immature technological and institutional infrastructure. However, Seocho district, who waited until the deficiencies had been sufficiently fixed since late majorities, succeeded at incremental diffusion. Since its invention by Gartner cooperation, the Hype Curve Model has not received enough attention in academia. This paper demonstrates its explanatory power for innovation diffusion. Similarly, this paper focuses on the importance of institutional framework in the diffusion of innovation. Lastly, we compare the behavior of two local governments in supporting and diffusing RFID systems to draw relevant policy implications for innovation diffusion.

Despite the growing amount of mobile peer-to-peer (P2P) payment applications available on mobile app stores, these applications are still in their infancy and have yet to see mass adoption. This study aims to explore the factors that influence the adoption of such mobile P2P payment applications by using a large-scale data set based on the tracking of users' actual mobile application usage behavior. Our main findings reveal that the duration of each session that users use of traditional bank application has a significant relationship with their adoption of mobile P2P payment applications. In addition, we explore the social aspect of such mobile P2P payment applications by analyzing their social network applications usage and found that the amount of social network service applications used and usage duration positively impacted one's adoption of mobile P2P payment applications. These findings have important theoretical and practical implications for stakeholders of mobile P2P payment solution providers as well as intermediaries/banks who provide their own payment applications to their customers.
