The Determinants of the Repurchase in the Social Commerce
Son, Dal-Ho ;
The Journal of Information Systems, volume 24, issue 2, 2015, Pages 1~22
DOI : 10.5859/KAIS.2015.24.2.1
Purpose This study identified the factors influencing on the continuous purchase of social commerce and analyzed the proposed model empirically using structural model. Design/methodology/approach Five independent factors such as economic benefit, social pressure, personal innovativeness, security and reputation and two mediating factors such as value perception and trust were extracted and relationships were explored. This study was carried out through customer survey and statistical analysis on the survey. Findings The result showed that three independent variables such as economic benefit, social pressure and security significantly affected on value perception and trust. Moreover, personal innovativeness and reputation did not have significant influence on customer purchase intention showing different result from the cases of traditional electronic commerce. The results of this study are meaningful in that factors affecting customer purchase intention in social commerce were identified from comprehensive perspective and the importance of customer profit and social influence was verified through empirical study in social commerce.

Yoo, Hosun ; Lee, Namyeon ; Kwon, Ohbyung ;
The Journal of Information Systems, volume 24, issue 2, 2015, Pages 23~52
DOI : 10.5859/KAIS.2015.24.2.23
Purpose This study aims to understand the role of digital knowledge in accepting the green technology. This study combined digital option theory with the second version of the Unified Theory of Acceptance and Use of Technology (UTAUT2). Contrary to other studies in which the UTAUT2 is used to explain IT adoption behavior, we look at the relationship between IT and the UTAUT2 from a new angle, incorporating an important aspect of IT, that is, digitized knowledge richness, as a determinant of the UTAUT2. Design/methodology/approach Grounded in the UTAUT2, a content analysis was conducted to investigate novel constructs dedicated to explaining green technology adoption. In this study, an amended version of the UTAUT2 specific to green technology is offered that better explains the green technology adoption behavior of consumers. Using the items identified by content analysis, we developed a questionnaire with 36 survey items. We measured all the items on a seven-point Likert-type scale. We randomly selected 402 survey respondents from a set of panel data. After a pilot study, we analyzed the main survey data by using PLS 2.0M3 and SPSS 20.0, and employed structural equation modeling to test the hypotheses. Findings The results suggest that the UTAUT2 was found to be extendable to technologies other than conventional IT. Social influence is more significant than conventional utilitarian and hedonic-based constructs such as those utilized in the UTAUT and UTAUT2 in explaining adoption behavior in the context of green technologies. The hypothesized connection between digitized knowledge richness and adoption intention was supported by the results of studies on the role of IT in formation of attitudes toward eco-friendly production. The results also indicate that digital knowledge can also encourage people to try green technology when they learn that their peers are already using the technology successfully.

Park, Hyun-Sun ; Kim, Sang-Hyun ;
The Journal of Information Systems, volume 24, issue 2, 2015, Pages 53~72
DOI : 10.5859/KAIS.2015.24.2.53
Purpose The purpose of this study was to investigate the factors affecting the users' stress and using reluctant intention to use social network service(SNS). This study especially focused on stress of SNSs' user. Because SNS has led to negative effects such as invasion of privacy, addiction and social overload recently. In addition, adverse effects of SNS had caused SNSs' user to feel stress and fatigue. Design/methodology/approach This study developed hypotheses to empirically examine the factors that affect SNS users' stress and using reluctant intention. In order to verify research hypotheses, this study collected data from 362 users who currently use the SNS in Korea. Further, we used the smartPLS analysis. Findings The results of this study are as follows; First, reputation perception, unwanted relation burden, privacy concern, information overload and interaction overload had a significant positive effect on SNS users' stress. But international influence had no significant positive effect on SNS users' stress. Second, SNS users' stress had a significant positive effect on using reluctant intention. The results of this study provides theoretical foundations on the research for dark side of SNS and implies that SNS providers are in need of exerting an effort to minimize the negative aspects.

Purpose Information security industry is rapidly growing, but has been confronted with many challenges in a business environment. One of them is the imbalance between supply and demand of information security manpower, which has caused an insecure market situation. Therefore, this study has derived factors of promoting and hindering information security manpower from governance, academics, corporations, and workforce perspectives, and has analyzed a sequence of cause and effect of each factor. Design/methodology/approach This study is an exploratory research based on the interviews. The causal loop diagram (CLD) was developed to deduce key issues and propose alternatives. Findings The result of this study is expected to help the development of information security manpower in Korea, by minimizing the potential negative effects as well as maximizing the positive effects. This study found out the dynamic causes and effects of the security manpower system in each stakeholder's perspective. The cause-and-effect relationships between the stakeholders will be able to contribute to solve the imbalance of supply and demand in security manpower system.

Choe, Jong-Min ;
The Journal of Information Systems, volume 24, issue 2, 2015, Pages 97~116
DOI : 10.5859/KAIS.2015.24.2.97
Purpose This study suggested the four forms of inter-organizational relationships(IORs): partnerships, inter-dependence relationship, trust relationship, and market relationship. The purposes of this study include the demonstration of four forms of IORs and the investigation of the relationships among forms of IORs, inter-organizational information flow(IOIF), kinds of e-commerce strategies, and the supply-chain performance of a firm. Design/methodology/approach The empirical data were collected through post-survey. 92 survey data were collected. With a cluster analysis, we confirmed four types of IORs, and the relationships among critical variables. Findings The results of cluster analysis showed that according to the types of IORs, the frequency and quality of IOIF are different. Appropriate kinds of e-commerce strategies were examined under the each types of IORs, which cause specific patterns of IOIF. It was found that the adoption of e-procurement strategy can improve the supply-chain performance of a firm in trust relationship. It was also observed that under partnerships, the use of e-partnerships strategy can contribute to the improvement of supply-chain performance.

Purpose The number of Tablet PC users has recently increased in steep, which started to offer media companies more opportunities to enter into a new business field. Based on Information System Success model, this study finds that tablet magazine's quality factors influence perceived usefulness, user satisfaction and intention of continuous use. Design/methodology/approach We conducted a survey for 20-40's Tablet PC users. After pilot study, we analyzed the main survey data by using SPSS 18.0 and AMOS 18.0, and employed structural equation modeling to test the hypotheses. Findings Our research results are summarized as follows : First, information quality has a positive impact on user satisfaction, but not on perceived usefulness. Second, service quality has a positive impact on perceived usefulness, but not on user satisfaction. Third, perceived usefulness positively influences user satisfaction. Fourth, user satisfaction positively influences the intention of continuous use. In particular we found that Tablet PC usage experience had a moderating effect on the relationship between perceived usefulness and user satisfaction.

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.

Jeong, Sung-Wook ; Kim, Jun-Woo ;
The Journal of Information Systems, volume 24, issue 2, 2015, Pages 163~188
DOI : 10.5859/KAIS.2015.24.2.163
Purpose The healthcare services have drawn so much public attention, and many organizations such as schools and companies require the individuals to undergo the periodic health examination. In general, however, the mass health examination services are not managed in systematic way, and both examinees and medical staffs often experience much inconvenience while preparing, undergoing and managing the services. To address such problems, this paper aims to design the Health Examination Management System (HEMS), an integrated management system for mass health examination operations management, and implement its prototype. Design/methodology/approach First of all, HEMS enables the medical staffs to efficiently collect and manage the examination result data by supporting examination service management. Second, the users can efficiently analyze the cause-and-effect relationships among the examination items by using the visualization tool of HEMS based on the cluster heat map. Finally, the HEMS provides the operational supports for evaluating and managing the service performances. Findings The HEMS indicates that the conventional operations management approaches can be incorporated into the mass health examination services, and it is expected that the proposed system enables the examinees and the medical staffs to participate in such services in more efficient way.
Users' Status Quo Bias in the Mobile Application Context : From the Myopic Loss Aversion Perspective
Park, Sang-Cheol ;
The Journal of Information Systems, volume 24, issue 2, 2015, Pages 189~208
DOI : 10.5859/KAIS.2015.24.2.189
Purpose While individuals have unique abilities for planned behavior, they also often act irrationally. In this study, we draw on myopic loss aversion perspective as a meta-theoretical lens to explain why mobile applications users have inertia from updating their applications, ultimately leading them to use current version of applications. Design/methodology/approach Based on a survey of 219 users, this study conducts its research model using partial least square analysis and also demonstrates that both subconscious triggers (habit and anxiety) of system 1 thinking and conscious triggers (sunk cost and transition cost) of system 2 thinking promotes user's inertia, thus leading to the willness to continue use current versions. Findings By grounding the research model in the combination of both status quo bias and dual information processing theory from the behavioral economics, this study provide an alternative theoretical lens to describe why mobile users hesitate to update their applications. The results of this research show that all triggers have significant impacts on inertia. This study also found that the relationship between inertia and willingness to continue to use current version was positively significant.

DOI : 10.5859/KAIS.2015.24.2.209
Purpose This study investigates the relationships between various attributes of smart banking (convenience, security, convergence, and economy), user features (familiarity and innovativeness), perceived usefulness, trust, satisfaction, and continuance intentions and provides a comparison of Google's Android OS and Apple's iOS. Design/methodology/approach We considered a sample of 245 respondents and used structural equation modeling to analyze the data. Findings The results indicate that convergence and familiarity significantly affected perceived usefulness and that security and economy significantly affected perceived trust in smart banking services. The relationships of security, economy, and innovativeness to perceived usefulness and those of convenience and familiarity to perceived trust were stronger for the Android OS than for iOS. The study contributes by proposing an integrated framework and providing a comparison between the Android OS and iOS in the context of smart banking.
