CAPM explains the rate of return for the risk asset by $\beta$, systematic risk. There are some assumption in CAPM. But CAPM can not explain the movement of stock price sufficiently due to limitation of the assumptions. Therefore many scholars study which variables with the exception of $\beta$ effect on the rate of return of risk asset for supplementing this limitation by using PER, size of firm etc.. But it will be natural that PER, size of firm etc. to be determinant factors of $\beta$ also effect on the abnormal rate of return, because PER, size of firm etc. used in their studies already effect on determination of $\beta$, . That is, the determinant factors of $\beta$ effect on determination of abnormal rate of return according as $\beta$, effects on abnormal rate of return. Therefore, this study tests empirically how the determinant factors of $\beta$, effect on determination of$\beta$, ,and how $\beta$ and the determinant factor of $\beta$ effect on the abnormal rate of return in CAPM.

Purpose: The aim of this study was to determine the related factors for psychological crises in Korean middle aged adults. Methods: RISS, KISS, National Assembly Digital Library, CINAHL, and PubMed were searched for relevant articles published until October 3, 2016. Finally, a total of 23 studies were included. Meta-analysis of the studies was conducted using Comprehensive Meta-Analysis 3.0 software to calculate the effect size. Results: The related variables of psychological crisis were categorized into 23 variables and 5 factor groups. The effects size (ES) of the overall defensive variables was -0.28. In the defensive factors, the psychological factor (ES=-0.67), followed by cognitive and behavioral factor (ES=-0.34), physical factor (ES=-0.31), and social relational factor (ES=-0.29) had the greatest effect on psychological crises. The effects size of the overall risk variables was 0.48. In the risk factors, the physical factor (ES=0.61) had the greatest effect on psychological crises, followed by the psychological factor (ES=0.53), and cognitive and behavioral factor (ES=0.10). Conclusion: An intervention program is needed to strengthen the defensive factors and reduce the risk factors for psychological crises of Korean middle aged adults.

This paper presents the traffic speed limit of heavy vehicles at each wind velocity region, which is based on their accident risk analysis under cross-wind. The variables for the accident risk analysis are overall height, overall length, intake weight, and friction coefficient of the road surface. It was confirmed from analysis results that the risk of overturning increased with higher overall height and length, and the risk of sliding decreased with higher intake weight. The risk of sliding was largest at the friction coefficient of 0.1, and the risk of overturning was lagest at friction coefficient more than 0.25. Finally, traffic speed limit was proposed by using the accident risk analysis.

Purpose: The aim of this study was to investigate the relationships among gender, information-seeking styles, and high risk behavior in Korean adults. Methods: A survey utilizing a structured questionnaire was used to examine the relationships of the study variables. Eight hundred fifty six adults were recruited and this group consisted of 403 females and 453 males. Information seeking style and high risk behavior were measured by Miller Behavioral Style Scale revised by Zurren and Wolfs, and High Risk Behaviors checklist developed by Lee, respectively. Results: Differences between gender were significant in information-seeking styles and high risk behavior. Monitoring and blunting scores were both higher in female than male, and high risk behavior was higher in males than females. The blunting style was positively related to high-risk behavior and the monitoring style was negatively related to high risk behavior. Conclusion: To intervene with high risk behavior effectively, individual differences such as gender and information seeking style should be considered. In addition, the research about well-designed health information support is needed in the future.

The purpose of this study is to be aware of the relationship between the perceived risk and purchasing intention after investing the impacts by 3 factors-consumer, media, and product characteristics on the perceived risk. The influence on perceived risk is categorized based on the 3 factors' combinations. The result of this study shows that the each characteristics of media, consumer, and product affect consumer's perceived risk and also this risk is affected by the relationship among these 3 independent variables. These results mean that the consumer's perceived risk about buying goods at the internet shopping mall or TV home shopping cannot be measured by a single dimension. Finally, it has a negative relationship between the perceived risk and purchasing intention. Implications for managers' use of shopping media are discussed in terms of the product and media characteristics fit.

This study examined the insolvency of debtors using multiple-indicator approaches and compared the outcomes across income levels with the 2016 'Household Financial and Welfare Survey'. This study used (1) the total debt to total assets ratio (DTA), (2) the total debt service ratio (DSR), and (3) the Household Default Risk Index (HDRI) recently developed by the Bank of Korea. Households in the lowest income quintile were more likely to be insolvent than any other income group. Demographics, such as age and gender of the household head, and most of the financial variables significantly increased the likelihood of insolvency based on the DTA. The number of household members and job status increased the likelihood of insolvency based on the DSR. Also, age, gender of the household head, and most of the financial variables increased the likelihood of household insolvency based on the HDRI after controlling for other demographics and financial variables.

The purpose of the present study was to identify variables for predicting types of outsiders and possible mitigating factors in bullying situations. Participants were 344 $5^{th}$, $6^{th}$ and $7^{th}$ grade students(159 boys and 185 girls). Involvement of outsiders in bullying was examined by proportion. Major findings were that; (1) Over half of the sample(65.4%) were involved in bullying by either actively reinforcing(bully-followers; 6.4%) or passively observing(bystanders; 59.0%); 34.6% were defenders of victims. (2) Multiple discriminant analysis yielded a function of 3 variables(empathy, risk burden, and prosocial moral reasoning) that was effective in classifying bully-followers, bystanders, and victim-defenders. Empathy and prosocial moral reasoning predicted victim-defenders and risk burden predicted bully-followers and bystanders.
