Recently, the breakdown of online banking servers and the leakage of customer information give rise to much concern about the security of information systems in financial and banking companies in Korea. The enforcement of security for information system becomes much more important issue than earlier. However, the security reinforcement of information system is restricted by a budget. In addition, the activities' cost to secure information system from threatening are under uncertain circumstances and should be established by a human decision maker who is basically uncertain and vague. Thus, making the budget for information system is exposed to any extent of the risk for these reasons. First, we introduce brief fuzzy set theory and fuzzy AHP (Analytic Hierarchy Process) methodology. Then, the cost elements that comprise yearly budget are presented and the priorities among the cost elements are calculated by fuzzy AHP. The cost elements that are exposed to risk are evaluated from the both perspectives of the risk impact and risk occurrence possibility which are expressed as linguistic terms. To get information on the risk profiles-pessimistic, most likely, and optimistic-for each cost element, the evaluation is accomplished and the result is presented. At last, the budget ranges-minimum, mode, maximum-for each cost element are estimated with the consideration of the risk profiles.

Consumers purchase bakery products and evaluate them with various wants and needs when they need them. It shows that there are changes and improvements in quality factors like nutritional consideration rather than simply eating for survival. The purpose of this study was to research how well the consumers perceive necessary nutritional information, how nutritional information on bakery products affects the consumers' perceived risk and evaluation, and how consumers' perceived risk on bakery products affects their evaluation on them. The research was done through surveys for the people in the Busan Metropolitan area. 200 out of 250 answers were used in analyzing frequency, factor, and simple regression through SPSS Win 10. The findings were as follows; first, the more nutritional information consumers have, the less perceived risk they feel, i.e., positive nutritional information affects reducing the consumers' perceived risk. Second, as perceived risk gets reduced, consumers' evaluation on bakery products has meaningful influence on their perceived risk level. Third, these consumers' perceived risk affects their evaluation on bakery products meaningfully. The results of this study can be the meaningful base of information sources in establishing marketing strategies in bakery industry.

In the aftermath of the COVID-19 pandemic, the importance of collective efforts in promoting health preventive behaviors is accentuated, bringing sociopolitical factors into focus. To fully capture psychological drivers of health preventive behaviors in risk situations, anchored on the Model of Risk Information Seeking and Processing (RISP; Griffin, Dunwoody, and Neuwirth 1999), in retrospect of the recent COVID-19 pandemic, we explored whether and how individuals' vaccination behaviors are predicted by RISP-related variables (information insufficiency, affective responses, perceived information gathering capacity, subjective norms) and one's political identity. Findings from a survey of 705 adult participants in the U.S. showed that the effects of one's risk information insufficiency on his or her information seeking and affective response regarding the pandemic, which is also related to their risk susceptibility perceptions. More importantly, the impact of political identity on one's perceived risk susceptibility, and its association with vaccination behaviors are also identified. The findings of this study provide valuable insights for the development of effective health communication strategies for preventive health behaviors.

In information systems, "trust" and "risk" have been explored by a few trust-related research studies before, but as two separate issues. The way in which these studies have been designed, however, does not help clarify the relationship between trust and risk since they are studied as unconnected determinants of trusting behavior in electronic commerce. As such, this research attempts to examine and specify the relationships among the core constructs surrounding the issue of trust such as risk and trusting behavior. The context of Internet banking adoption is used to develop a conceptual model that incorporates the direct effects of trust and perceived risk on trusting behavior as well as the mediation of the relationship between trust and trusting behavior by perceived risk. The findings show that perceived risk mediates the relationship between trust and trusting behavior. Specifically, trust in the Internet as a banking medium significantly influences the adoption of Internet banking both directly and indirectly through perceived risk of Internet banking. Trust that the bank will not take advantage of consumers significantly influences the trusting behavior through perceived risk of Internet banking. This study, thus, extends research on trust in e-commerce by simultaneously examining the influence of trust and perceived risk on e-commerce adoption.

Risk management is recognized as a significant element in Information Security Management while the failure mode and effects analysis (FMEA) is widely used in risk analysis in manufacturing industry. This paper aims to present the development work of the Information Security FMEA Circle (InfoSec FMEA Circle) which is used to support the risk management framework by modifying traditional FMEA methodologies. In order to demonstrate the "appropriateness" of the InfoSec FMEA Circle for the purposes of assessing information security, a case study at Hong Kong Science and Technology Parks Corporation (HKSTP) is employed. The "InfoSec FMEA Circle" is found to be an effective risk assessment methodology that has a significant contribution to providing a stepwise risk management implementation model for information security management.

본 연구는 2015년 메르스 위기 중 두 차례에 걸쳐 동일한 응답자들을 대상으로 수집한 온라인 패널 서베이 자료를 이용해 개인의 위기관련 정보탐색 처리에 미치는 요인과 위험정보 탐색처리가 위험 방지행동에 긍정적 영향을 미치는지를 검증하였다. 또한 메르스 위기 상황에서 SNS를 통해 가족, 친구, 지인과 활발한 소통이 메르스 위기관련 정보의 탐색, 처리 그리고 방지행동에 어떤 조절 영향을 미치는지도 살펴보았다. 연구 결과 위기정보 탐색처리 모델은 한국의 메르스 위기상황에서 그 타당성이 검증되었으며, 특히 메르스 관련 정보의 적극적 탐색과 체계적 처리가 이후 메르스 방지 행동에 긍정적 영향을 미쳤다는 것을 알 수 있었다. 이와 함께, SNS 이용량에 따라 나뉜 두 집단에서 메르스 관련 정보의 탐색과 처리에 미치는 요인과 그 결과에 유의미한 차이가 있음을 알 수 있었다. SNS 이용에 따른 조절효과는 주로 부정적 감정과 사회적 동기요인을 중심으로 드러났고, 연구결과는 메르스 위기 중 SNS의 이용이 불필요한 공포를 조장한다는 우려와는 달리 위기의 지각이 부정적 감정으로 이어지는 관계를 완화시켜주고, 나아가 사회적 동기요인을 자극하고 메르스에 대한 체계적 정보처리를 강화시키는 영향을 미쳤다는 것을 보여주었다.

Purpose: This study reexamines the test on the pricing of accruals quality. Theory suggests that information risk is a priced risk factor. Using accruals quality as the proxy for information risk, researchers have tested the pricing of information risk. The results are inconsistent potentially because of the information shock in the realized returns that are used as the proxy for expected returns. Based on this argument, this study revisits this issue excluding information-shock-free measure of expected returns. Research design, data and methodology: This study estimates expected returns using the vector autoregression model. This method extracts information shocks more thoroughly than the methods in prior studies; therefore, the concern regarding information shock is minimized. As risk premiums are larger in recession periods than in expansion periods, recession and expansion subsamples were used to confirm the robustness of the main findings. For the pricing test, this study uses two-stage cross-sectional regression. Results: Empirical results find evidence that accruals quality is a priced risk factor. Furthermore, this study finds that the pricing of accruals quality is observed only in recession periods. Conclusions: This study supports the argument that accruals quality, as well as the pricing of information risk, is a priced risk factor.

The study examines the relationship between credit risk and operational risk (understanding of risk management, risk identification, risk assessment and control, and risk monitoring) on risk management practices followed by private and public sector commercial banks. The cross-sectional data method was used to check the impact of risk management practices. Data was collected from the bank employees and a total of 284 respondents were finally selected for further analysis. Measurement Invariance of Composite Models analysis is used to test the quality of the measurement model for sub-samples, and multi-group analysis is used for path analysis in sub-sample through PLS-SEM. The findings of the study as the total sample show that both types of banks are managing adequate and significant risk management practices. On the other hand, sub-groups' results show private sector banks are more momentous than public sector banks. Risk identification is significantly different at the sub-group level, which shows public sector banks are more concentrating on this type of risk. Understanding of risk management has no significant effect on both types of banks and risk assessment & control for public sector banks, and there is a difference in the risk management practices among private and public sector commercial banks.

Based on the IS literature on software project risk management, we developed an integrated model to investigate the risk factors and risk management factors in project development. We also analyzed the interrelation between project risk and project risk management. The questionaries are collected from 83 project leaders. We tested reliability and validity of the measure and analyzed the obtained data. The results support our risk-based hypothesis that shows the importance of risk management in reducing project risks and improving performance of project and process.
