본 연구는 개인투자자의 비합리적 투자의사결정 및 투자행동에 영향을 미치는 중요한 심리적 요인 중 하나가 개인투자자의 과신이라는 많은 행동재무론적 연구결과들을 중심으로, 개인투자자의 투자에 대한 확신(투자확신)에 영향을 미치는 자기고양적 지각 요인들을 탐색적으로 알아보았다. 또한, 개인투자자의 주식투자와 관련된 자기고양적 지각 요인이나 투자확신과 같은 심리적 요인이 개인의 잘못된 위험투자행동에 영향을 미치는지를 알아보았다. 연구결과, 개인투자자의 투자확신에 영향을 미치는 자기고양적 지각 요인과 투자확신에 있어 남녀 간의 차이가 발견되었다. 즉, 남성 투자자의 경우에는 '자신의 투자능력에 대한 긍정적 평가' 요인이, 여성 투자자의 경우에는 '수익률에 대한 낙관적 기대' 요인이 투자확신에 영향을 미치는 것으로 나타났으며, 남성 투자자가 여성 투자자에 비해 투자에 대해 더 확신하는 것으로 나타났다. 또한, 개인투자자의 '자신의 투자능력에 대한 긍정적 평가', '자신의 통제가능성에 대한 확신', 그리고 '수익률에 대한 낙관적 기대'와 같은 자기고양적 지각 요인이나 투자확신과 같은 심리적 요인들이 개인의 잘못된 위험투자행동에 영향을 미칠 수 있음을 부분적으로 증명하였다. 그러나 그 영향은 크지 않아, 개인투자자의 심리적 요인과 잘못된 위험투자행동 간을 매개해 줄 수 있는 여러 다른 변수들에 대한 연구가 필요함을 시사해준다.

Objectives: This study examined the trend of alcohol-related research, with a specific focus on adolescent problem drinking, to provide evidence for prevention and intervention for adolescent alcohol problems and alcohol policy in Korea. Methods: A total of 17 studies examining adolescent problem drinking were included for meta-analysis. Using CMA (Comprehensive Meta-Analysis) 2.0, the effect sizes of correlation coefficients of variables related to adolescent problem drinking were analyzed. Results: 176 variables were extracted under 4 higher categories and 20 sub-categories. Variables were extracted using the four higher categories, namely individual, family, environmental, and demographics, as the theoretical framework. Results showed that most studies on adolescent problem drinking focused mostly on individual factors followed by family factors. Variables including drinking motivation, drinking expectancy, and peer relations showed relatively higher effect size. Conclusions: Study findings suggest the importance of balance between individual and environmental factors in examining problem drinking among adolescents. In order to provide evidence for alcohol policy, more attention should be given to macro environment that are known to influence adolescent drinking.

The purpose of this study is to provide a brief overview of the helicopter pilot training system applied to the Army, and to examine what factors positively affect the successful flight training of helicopter pilots. For this purpose, we analyzed the correlations between various factors such as individual characteristics, selection factors, flight aptitude evaluation, theoretical subjects test, and self-life evaluation. As a result, it was found that only the flight experience was influential on the individual characteristics at the beginning of the training course, and the learning achievement represented by the test of theoretical subjects was positively influenced throughout the flight training course. This reaffirms the fact that an individual's high level of motivation or effort influences his flight training performance. These results are expected to be useful indicators for future development of pilot selection system and pilot training system.

Objectives: This study divided the factors that affect participation in health screenings into individual, household, and regional levels and conducted a multi-level analysis to identify the factors related to participation in health screenings. Methods: Participants from the 2017 Community Health Survey were classified into 2 groups (under 40 and 40 or older). A multi-level logistic regression analysis was conducted to identify the factors that affected participation in health screenings. Results: The screening rate of the participants was 69.7%, and it was higher among participants aged 40 and older (80.3%) than it was among participants younger than 40 (49.8%). At the individual level, the factors that influenced participation in health screenings included age, economic activity, smoking status, physician-diagnosed hypertension, and a moderate or high physical activity level. At the household level, the odds ratio of participation in health screenings was high for participants who lived in single-person households, lived with a spouse, earned a high monthly household income, and were not beneficiaries of national basic livelihood security. At the regional level, the odds ratio at the 95% confidence interval level of participation in health screenings was high for participants who had trust in the local community and lived in an area with a proportionally high social welfare budget. Conclusions: This study analyzed nationalwide data and confirmed that individual, household, and regional characteristics affected participation in health screenings. Therefore, policies that prioritize the improvement of regional level factors and especially household level factors are likely to be the most effective for improving the screening rate.

This study examined different individual and parental factors that affect children's achievement motivation. For an analysis, perceived competence, intrinsic locus of control were included in individual variables. For parental variables, parental support and achievement pressure and marital conflict were examined. The sample consisted of 561 fifth and sixth grade children. Statistics and methods used for the data analysis were Cronbach's alpha, Factor analysis, frequency, percentage, Pearson's correlation, and Hierarchical Regression. Several major results were found from the analysis. First, girl's achievement motivation was higher than boys. No age difference was found between fifth and sixth grade. Second, boy's and girl's achievement motivation had a positive correlation with perceived competence, intrinsic locus of control, parental support and achievement pressure but a negative correlation with parental marital conflict. Third, important variables predicting boy's and girl's achievement motivation were perceived academic competence, parental achievement pressure and perceived social competence. Important variables predicting boy's individual and social oriented achievement motivation were perceived academic competence and parental achievement pressure. On the other hand, important variables predicting girl's individual oriented achievement motivation were perceived social competence, perceived academic competence, intrinsic locus of control and parental achievement pressure. Important variables predicting girl's social oriented achievement motivation were parental achievement pressure, perceived academic competence and mother's support.
