While innovative information technologies have been adopted quickly into our daily life, we often experience the discontinuance after being temporarily adopted. This paper aims to study the factors influencing discontinuance on Microblog to Chinese users who already temporarily adopted it. According to empirical analysis, complexity and security show up their influences into all perceived risks, and inconvenience innovation and subjective norm just effect social risks. And perceived risk shows influences in every reasons for discontinuance, especially lots influences come from complexity. So according to these results, it is needed that the complexity of Microblog should be reduced.

In the entire process of disaster management, it is very significant to construct related information as well as perform quantitative assessment of damage losses with respect to minimizing the effect of disasters. Many countries have paid much attention not only to studying risk assessment methodologies including constructing inventories, hazard mapping, vulnerability assessment and direct/indirect damage loss estimation, but also to developing risk analysis tools investigated in this paper. We conducted comparison studies of representative earthquake damage risk analysis tools, and the result of this study is able to provide useful information to decision makers and researchers who can contribute to development of effective disaster management.

Information security has been a major concern in organizations. The longstanding question of how to improve employees security behaviors and reduce human errors remains unanswered and requires further exploration in the information security domain. To do this, we propose a risk compensation theory-based model and examine the model. Research results shows that the relationships between information security countermeasures and information security compliance intention of employees are moderated by system vulnerability. However, the finding is contrary to the previously held risk compensation assumption and deserve further study. In addition, system quality does not play a moderator role in the relationship. Conclusions and implications are discussed.

As the issue of selling wine online has been raised in an attempt to implement FTA programs in a more effective way, wine will be available online in the near future in Korea. Thus, this study aimed at identifying key factors which will contribute to reduce various kinds of risks perceived by online customers, and investigating the structural relationships between those factors and perceived risks. Site quality of online wine shop(information quality, system quality), trust in online wine shop were selected as key predictors of perceived risks and research model was established using those factors. Data were collected from those who have experienced in using online wine store, and the research model was tested using valid data. Results of testing research hypotheses using data from survey respondents showed that information and system quality exerted an impact on trust in online wine shop. It was proven that information and system quality posited an impact on time risk whereas they was not related to performance and psychological risk. In addition, trust in online wine shop was shown to be related to time risk, performance risk, and psychological risk.

This study, for the reinvigoration domestic LCCs (Low Cost Carriers) in Asian air market which is in developing stage now, aims to analyze the management risk through the operation cases of domestic and foreign areas and then to derive a risk management plan to reinforce the competency of domestic LCCs. As for the major potential risk factors for LCCs in Asia-pacific market, the first is the absence of growth strategy. Then, the second is the problems in airline route, the typical problem of subsidiary companies of major air lines. The third is the lack of specialists and professional manpowers. In order to cope with such risk factors, rapid growth should be controlled and competition with parent company by entering to parent company's airline route should also be avoided. At the same time, there should be a comprehensive supporting system to foster specialists and professionals in this industry.

This study investigates to investigate the factors that influence user resistance of mobile payment services. We suggested individual and technical characteristics of mobile payment services as factors influencing perceived risk and user resistance. In addition, we suggested negative security recognition as moderating variable. To test the proposed hypotheses, we collected 349 survey responses from the users of mobile payment services and conducted structural equation modeling with SmartPLS2.0. The results show that, first, negative social influence, risk aversion and distrust in existing services had an effect on the perceived risk. Second, the pace of change and vulnerability had an effect on the perceived risk. Third, perceived risk affected the user resistance while negative security recognition is related to the relationship between perceived risk and user resistance.

This study was conducted to detect metabolic syndrome risk factors and gender difference in adults. 18,616 cases of adults are collected by Korea Health and Nutrition Examination Study from 2016 to 2019. Using 4 types of machine Learning(Logistic Regression, Decision Tree, Naïve Bayes, Random Forest) to predict Metabolic Syndrome. The results showed that the Random Forest was superior to other methods in men and women. In both of participants, BMI, diet(fat, vitamin C, vitamin A, protein, energy intake), number of underlying chronic disease and age were the upper importance. In women, education level, menarche age, menopause was additional upper importance and age, number of underlying chronic disease were more powerful importance than men. Future study have to verify various strategy to prevent metabolic syndrome.

The current study examined the moderating effect of visual cues in eWOM on the relationship between perceived risk and purchase intention. Specifically, the study tested the different directions of the moderating effect in positive and negative eWOM. Two studies from a 2 (perceived risk: high vs. low) by 2 (visual cue: presence vs. absence) experimental design were used with online subjects. Findings from study 1 (n=123) supported that visual cues in positive eWOM help to reduce the negative effect of perceived risk on purchase intention. However, study 2 (n=122) showed that visual cues in negative eWOM intensify the negative effect of perceived risk on purchase intention. The findings demonstrated that visual cues in eWOM influence consumers' decision under high risk conditions. We discussed findings of this study how visual cues in positive and negative eWOM can be strategically managed for new online sellers.

오늘날 독자들을 매료시키고 있는 디지털 문학이란 과연 19세기 소설처럼 온화하고 책임감 있는 것일까, 아니면 환각 작용을 일으키는 마약처럼 위험스럽고 치명적인 것일까, 현재 우리는 뉴미디어 혁명의 한가운데에서 있다. 14세기의 인쇄 활자나 19세기의 사진 기술이 당대의 사회와 문화에 혁명적인 충격을 주었던것처럼, 이제는 모든 문화가 컴퓨터를 매체로 생산 ㆍ배포ㆍ의사소통하고 있다. 본고에서는 헐리우드 공식을 기반으로 한ㆍ미ㆍ일 애니메이션 시나리오 구성 방식으 비교했다.
