스마트폰 기기 내에 저장되는 사용자 정보가 다양화되어 개인정보에 대한 위협도 함께 증가하고 있다. 패턴 잠금, 지문 인식 등 다양한 사용자 인증 기술이 스마트폰에 적용되어 있으나 사용자 의존적, 거부감 유발 등의 한계점을 보이고 있다. 최근 주목받고 있는 행위 기반 인증은 기기 사용과 동시에 인증이 가능하여 사용자에게 높은 편의성을 제공하나 타 인증 기술에 비해 정확도가 낮아 이를 개선하기 위한 연구가 꾸준히 수행되고 있다. 본 연구에서는 이전 연구에서 고려되지 않았던 앱 사용 정보를 새로운 인증 요소로 활용하는 방법을 제안한다. 또한 실제 앱 사용 상황을 고려한 데이터 수집 및 분석을 통해 제안 기술의 성능을 상세하게 분석한다.

With the competitive pressure and the development of information and communication technology, many organizations have introduced various kinds of enterprise-wide systems like enterprise resource planning (ERP) systems as strategic tools for the purpose of improving organizational performance. Despite their promised strategic benefits, however, their implementation has suffered from a high failure rate and difficulty in realizing the anticipated benefits. Previous studies have indicated that one of the most critical failure reasons is the lack of knowledge sharing and utilization across organizations. As a consequence, many information systems (IS) researchers have paid attention to examining the effect of absorptive capacity closely associated with knowledge sharing and transferring on IS usage performance. ERP systems implementation involves changes not only in systems but also in processes and other social dimensions, which can be related to organizational citizenship behavior (OCB) requiring appropriate communications and interactions among organizational members. A lack of communications and interactions due to a lack of OCB might lead to weak absorptive capacity and thus negatively influence knowledge sharing across organizations, because OCB facilitates a successful collaboration among functional units and positively impacts individual's attitude toward radical organizational change. With this motivation, this study has two research objectives. First, it introduces and tests a theoretical model accounting for the relationships among performance of ERP system usage, absorptive capacity, and OCB. Second, it examines a mediating role of absorptive capacity between OCB and performance of EPR system usage. Theoretical and practical implications of the study ware discussed, along with its limitations.

The purpose of this study was to examine the effects of the time spent on violent internet games and game overindulgence on aggressive behavior exhibited by elementary school-aged boys and to investigate the mediating effects of self-control on the relationship between children's game overindulgence and their aggressive behavior. The subjects of this study were 118 fourth to sixth grade boys from five elementary schools. The instruments used were the aggression subscale of the Korean-Youth Self Report (Oh, Ha, Lee, & Hong, 2001), a questionnaire of the time spent playing violent internet games developed by the authors, the Internet Game Addiction Scale for Children (Kim, Lee, Kim, Kim, & Kim, 2006) and the Self-Control Scale (Nam, 1999). The data were analyzed by means of a Structural Equation Model (SEM). The results were as follows. First, children's self-control mediated the relationship between game overindulgence and aggressive behavior. Second, the amount of time spent playing violent internet games had no effect on children's aggressive behavior.

The growth of mobile commerce (m-commerce) has been accelerated around the world. Why do e-retailers have to put a great deal of effort for the distribution of their mobile apps? The literature has paid little attention to the influence of the introduction of an e-commerce app on shopping behaviors of consumers. By analyzing the dataset of 2,342 users in Korea, this study aims to broaden our understanding of mobile shopping app usage across competing e-retailers and different channels. We found that a user's prior usage of a specific e-commerce mobile app increases her subsequent usage of its website through a mobile web browser. Thus, mobile apps do not cannibalize the mobile web channel, and there could be a complementary relationship. We also found that a user's usage of competitors' apps is positively associated with her subsequent usage of a specific e-commerce app. Because many consumers search products and compare prices across multiple e-retailers, having a mobile app helps an e-retailer be exposed to more potential consumers. This study is among the first to study the role of mobile apps in e-commerce by showing the dynamics of cross-channel and cross-vendor usage by a user.

Purpose: The study aimed to investigate the factors associated with long hours of smartphone usage and to identify the characteristics of the high-risk group among female middle school students in South Korea. Methods: The study analyzed the data of 13,648 female middle school students using their own smartphone extracted from the 13th Youth Health Behavior Online Survey (2017). The factors related to using smartphones for a long time was analyzed by binomial logistic regression. The characteristics of the high-risk group was defined by a decision tree analysis. Results: The average hours spent on smartphone usage was 269.54 minutes per day. The significant factors associated with the long hours of smartphone usage were grade, living with parents, perceived household economic status, perceived academic achievement, stress, sadness and hopelessness, the main purpose of smartphone usage, drinking, body mass index, breakfast, and satisfaction with sleep quality. The subjects showing low academic performance and having breakfast four times a week or less were more likely to use their smartphone for a long time. Conclusion: Based on the results of the research, we need to establish intervention strategies focusing on the factors influencing long-time usage of smartphone. Particularly, the subjects who show poor academic performance and skip breakfast frequently should be considered as the high-risk group for spending long hours on smartphone usage.
