This study investigated the relationship between consumers' knowledge and risk perception towards purchase intention of organic food. The data were collected from a sample of 311 housewives in Seoul and Ulsan. A structural equation modelling technique was used to test the causal model. The results indicated that subjective knowledge was significantly associated with purchasing organic food. Objective knowledge, in contrast, was only indirectly associated with purchasing organic food, through increased subjective knowledge and risk perception towards purchasing organic food. Risk perception towards organic food had a direct positive and relatively strong relationship with purchasing organic food. Implications of the results and limitations of the study were discussed.

We tried to do research on main views(risk and knowledge-based) and propose user knowledge as a factor to be managed in order to strengthen the performance. This study empirically analyzed the user-related and project management risk that affect the IT project performance, and verified user knowledge as a moderating variable. The survey was conducted for respondents who have experience on IT Project of public sector and data were analyzed by Smart PLS 3.0. The results show that low user-related and project management risks have a positive effect on performance. In addition, user knowledge has been shown to enhance the impact of two risks on performance. These findings are meaningful in that they emphasize the importance of user knowledge in public-sector IT projects, as well as the repeated verification of integrated research results.

The purpose of this study is to investigate the user's perception of security risk and examine its impact on the usage of Knowledge Management Systems(KMS). The findings of this study are three-fold. First, the overall user's perception of security risk is not high. However, there is a considerably big difference in the perception of security risk among users. This finding means that user's perception of a security risk is not based on the actual security effects but one's individual perception. Another finding is that user's perception of a security risk has a negative impact on the usage of KMS through "trust", which is a mediating variable in our study. This finding corresponds with the existing theory that security risk is oneof the critical sources of trust, and trust is a critical factor of user's acceptance of KMS. Finally, the result of this study reveals that activities devoted to security do not decrease the effectiveness and productivity of KMS. Our long-held cognition that security activity hinders the effectiveness and productivity of an information system is not particularly applied to the KMS.

The purpose of this study is to investigate the relationship between risk perception, knowledge, risk attitude, and health promoting behaviors of nursing college students. The data were collected from 168 university students of four-year nursing college in the city of D, C. The collected data were analyzed by independent t-test, one way ANOVA and Pearson correlation coefficient using SPSS WIN 20.0 program. As a result this study knowledge of fine dust was statistically significant in respiratory disease(t=1.92, p<.001). The risk attitude toward fine dust was statistically significant in respiratory diseases(t=2.05 p=.042), subjective health status(F=3.79, p = .012). There was a significant positive correlation between risk perception of fine dust and knowledge(r=.340, p<.001), risk attitude(r=.492, p<.001), and health promoting behaviors(r=.354, p<.001). Knowledge of fine dust and risk attitude(r=.401, p<.001), health promoting behavior(r=.296, p<.001), risk attitude toward fine dust and health care behaviors(r=.550, p<.001) also showed a statistically significant positive correlation. Based on these results, it will be necessary to develop a program to improve awareness and knowledge of fine dusts in nursing college students and to improve health promoting behaviors.

The objective of this empirical study is to examine the mediating and moderating effects of perceived risks on the relationship between knowledge, feelings and acceptance intention towards AI. Subjects in their teens to forties were surveyed and the final sample comprised 1,969 subjects. Data were analyzed using Mediation using Multiple Regression and Moderated Multiple Regression. Results showed that people's knowledge and feelings towards AI affected their acceptance intention of AI. Results also showed that the perceived risks of AI partially mediated and moderated the relationship between feelings and acceptance intention towards AI and moderated but not mediated the relationship between knowledge and acceptance intention towards AI. Overall, these results suggest that people's perceived risks of AI are associated more strongly with their feelings towards AI than their knowledge towards AI. Implications and directions for future research were discussed in relation to increasing general population's acceptance intention towards AI.

Within any income approach, a discount rate is used to convert some projected free cash flow to its presented value. In case of valuing companies, the most frequently used discount rate is the weighted average cost of capital(WACC) at the aggregate level. But technology valuation is different to discounting aggregate corporate cash flow since it is concerned about individual Intellectual property. Therefore, blindly applying standard discount rate such as WACC in technology valuation is unlikely to lead to the right result. The primary focus of this paper is to establish the structure of discount rate for technology valuation and to suggest the method of estimation. To determine an appropriate discount rate for technology valuation, the level of technology risk, market risk and competitive risk should be included in the structure of discount rate. This paper suggests the build-up model which consists of three components as a expansion of the CAPM. It includes (1) a risk-free rate of return, (2) general market risk premium and beta and (3) intellectual property risk premium related to technology risk and specific target market risk. However, there is no specific check list for examining the intellectual property risk until now and no specific method for quantifying its risk into risk premium. This paper developed the 10 element to determine the level of the intellectual property risk and applied estimation function such as linear function, natural log function and exponential function to transform the level of risk into risk premium. The limitation of this paper is that the range of intellectual property risk premium is inferred based on the information of foreign and domestic valuation agency. Finally, this paper explored the development of an intellectual property discount rate for technology valuation and presented the method in order to quantify the intellectual property risk premium.

This study was conducted to describe the attitude toward pressure ulcer prevention, knowledge and non-compliance risk for pressure ulcer prevention practice and degrees of nursing performance, as well as to examine the relationship among these variables. To accomplish this, we invited 397 nurses from four hospitals to complete surveys of attitude toward pressure ulcer prevention, knowledge and certainty for pressure ulcer prevention practice, and degrees of nursing performance. Non-compliance risk for pressure ulcer prevention practice was derived from the difference between knowledge and certainty for pressure ulcer prevention. The data were collected from March to June 2017 and analyzed by descriptive statistics, independent t-tests, ANOVA, and partial Pearson's correlation coefficient testing. The correct answer rate regarding the knowledge of pressure ulcer prevention practice was 79%, and the degree of pressure ulcer prevention nursing performance was $2.46{\pm}0.31$. The highest item of the non-compliance risk for pressure ulcer prevention practice was incontinence diapers prevent incontinence-associated dermatitis. There were significant negative correlations between non-compliance risk for pressure ulcer prevention practice and knowledge (r=-0.25, p<0.001), and degree of pressure ulcer prevention nursing performance (r=-0.13, p=0.009). Continuous education and furnishing practical guidelines for pressure ulcer prevention should be implemented to improve knowledge and certainty of pressure ulcer prevention practice.

This study aimed to investigate the effects of social disaster risk perception levels of Koreans on government trust. To this end, differences in disaster risk perception levels based on social disaster types and the effects of social disaster risk perception levels on government trust were analyzed. In the preliminary survey, three types of social disasters with high risk levels (bird flu, fine dust, and nuclear power plants) were selected. The survey was conducted on 1,109 Korean men and women aged 20 years and older. First, the analysis results demonstrated that social disaster perception levels differed based on social disaster types. Second, the results showed that, in terms of social disasters, proactivity, personal knowledge, familiarity, severity, fear, and risk associated with chances of recovery did not affect government trust. Third, the perception of delayed social disaster risk had a positive effect on government trust. Fourth, scientific knowledge about social disasters, control capabilities, lethality, and risk perception at the onset time had a negative effect on government trust. In conclusion, the implications and limitations of this study were discussed.
