The aim of this study was to analyze the impacts of perceived economic instability on drinking frequency in the mist of exercising the strong social distancing in the early phase of COVID19 pandemic. The data were collected from 1,117 adults aged between 19 and 70 across the nation from May 13 to May 19 in 2020 by Embrain, an on-line research company. We used only 820(73.4%) out of 1,117 who answered that they had a drinking in 2020. Bi-variate analysis and multivariate multinomial logistic regression were performed using STATA16. Multinomial logistic regression results showed that the increase of employment instability was related to the increase of drinking frequency, whereas the increase of income instability was related to the decrease of drinking frequency. In sum, the impact of perceived economic instability during the early phase of pandemic may be presented as an increase or decrease of drinking frequency depending on the effect of employment instability and income instability.

This study examines gender differentials in depression among Korean older adults. Using logistic regression and decomposition methods, this study analyzes factors that predict depression of a full sample and separate male/female samples, respectively. Further, this study decomposes factors that affect gender differentials in depression into two components: the distributions of individual variables and the returns to risk. This study finds the variables that separately predict depression by gender. For male, having a smaller social network is associated with depression; however for female, the number of falls is associated with depression. This study also finds that being married, having greater satisfaction with current financial situation, and having good physical health increases the gap between males' and females'depression. Married male have greater returns from marriage than females. If females had the same returns as male, then the gap would have decreased by about 40%.

This study aimed at developing a model for estimating fertility rates for Korea under some conditions. The model is expected to provide the basic information for establishing and evaluating the polices in prompt and adequate response to low fertility and population ageing. The model was established on the basis of experiences by some OECD countries in Europe, having experienced the fertility increase trend and being economically well-developed, because Korea has never experienced the steady increase in fertility rate since 1960. This study collected about 20 years' time series data for each of selected countries and applied to the regression model, which is called a 'panel analysis' to take into considerations both cross-sectional and longitudinal aspects of fertility change simultaneously. Simulation of the model for Korea and some panel countries showed a very small difference, less than 0.1, between the estimated rate and the observed rate for each year during 2006~2010. Thus, the model, as established in this study, is evaluated as accurate or well-fitted to a considerable extent.

This study was conducted to explore the factors that affect youth life satisfaction in order to find ways to increase their life satisfaction. For this purpose, we utilized data from the National Youth Policy Institute's '2021 Youth Socio-Economic Survey' to study 2,041 youth aged 18-34 as of 2021. The randomForest method was applied to explore various variables that affect youth life satisfaction. A total of 21 variables were analyzed, including demographic and socio-demographic factors and psychological and emotional factors.The results of exploring the variables affecting youth life satisfaction using randomForest are as follows. First, all 21 predictors were found to have an impact on young adults' life satisfaction. Second, the most significant impact on youth life satisfaction was found to be 'work values'. Third, it can be seen that young people's perceptions of society, such as 'political effectiveness' and 'perception of older generation', are also variables that affect youth life satisfaction. Based on these findings, the variables affecting youth life satisfaction are explained and discussion points are presented.

Questionnaires and blood pressure measurements were administered to 279 medical school undergraduates in 1987 to investigate the relationship between psychosocial factors and blood pressure as well as reliability and validity of the Framingham Type A Behavior Scale(FTA). The reliability coefficients of SCL-90-R and nh measured by Spearman-Brown haves split test were $0.57{\sim}0.91$. The factors of FTA extracted by principal component analysis were hard-driving competitiveness factor and impatience factor(2-factor solution) . The total score of nh was positively correlated with relative weight and place raised but the correlations were insignificant, and had significantly positive but weak correlations with depression, anxiety, hostility, paranoid, and psychoticism subscales of SCL-90-R. In the univariate analysis of blood pressures, relative weight and family history were significant in systolic pressure in males and economic status was significant in blood pressures in both sexes. For diastolic pressure, relative weight and frequency of alcohol intake were significant in males and relative weight was in females. After controlling relative weight, the frequency of alcohol intake for diastolic pressure and economic status for systolic pressure were significant in males. The important variables selected by stepwise regression analysis were relative weight and economic status for systolic pressure of males and relative weight and the frequency of alcohol intake for diastolic pressure. At the level of alpha 0.1, depression subscale was added to the model, changing coefficient of determination 0.206 to 0.217. In females, economic status and relative weight were selected for systolic pressure and for diastolic pressure body mass index alone, but the model of blood pressure for females was considered to be unstable due to small sample size(56). FTA was unrelated to the blood pressures in both sexes.

This paper measures and analyzes the performance of insurance companies in Korea in respect to sustainable development and suggest strategic implications based on the analysis. The correlation, regression, ANOVA, and t-test are employed. The results of this study are summarized as follows. First, it shows tat social index is important in the life insurance industry; however, the environmental index, is important in the non-life insurance industry. Second, the result gained by regressing the size and financial soundness on the performance of sustainable development demonstrates that the size variable is statistically significant. It suggests that size is a necessary condition for sustainable development. Finally, ANOVA shows that the small and medium sized companies have a significantly poor performance compared to the large companies concerning the social index and reputation index in the life insurance industry. The small and medium sized companies in the non-life insurance industry exhibit a significantly poor performance compared to the large companies in respect to all the indexes, except for the social index. Therefore, the small and medium sized companies make every endeavor in the poor indexes to improve performance.

Objectives: As suicide among the elderly population has been a critical issue in Korea, this study aimed to evaluate correlations of suicidal ideation with protective and risk factors among elderly who reside in a rural community. Methods: A total of 157 elders from Gyeongju city, who had attended senior centers in, were enrolled to answer questionnaires including the Geriatric Depression Scale Short Form-Korea and the Scale for Suicidal Ideation. Data were analyzed using SPSS 18.0K for Windows, and included t-test, Pearson correlation, and a three-step hierarchical multiple regression analyses. Results: Using the hierarchical regression analyses for predicting the elderly's suicidal ideation, male gender and social group variables were entered as predictors in the first step(adjusted $R^2$=0.107, P<0.05). Pain, ADLs, family support variables were not entered in the second step. Depression variable was the only predictor in the third step(adjusted $R^2$=0.384, P<0.001). Conclusions: Although this study confirmed the impact of depression on the suicidal ideation, elderly with risk factors including male gender and social isolation should receive a special attention from community health care professionals.
