The purpose of this study was to evaluate the usefulness of variables which were known to be related to blood pressure for discriminating between hypertensive and normotensive groups. Variables were obesity, serum lipids, life style-related variables such as smoking, alcohol, exercise, and stress, and demographic variables such as age, economical status, and education. The data were collected from 400 male clients who visited one university hospital located in Incheon, Republic of Korea, from May 1996 to December 1996 for a regular physical examination. Variables which showed significance for discriminating systolic blood pressure in this study were age, serum lipids, education, HDL, exercise, total cholesterol, body fat percent, alcohol, stress, and smoking(in order of significance). By using the combination of these variables, the possibility of proper prediction for a high-systolic pressure group was 2%, predicting a normal-systolic pressure group was 70.3%, and total Hit Ratio was 70%. Variables which showed significance for discriminating diastolic blood pressure were exercise, triglyceride, alcohol, smoking, economical status, age, and BMI (in order of significance). By using the combination of these variables, the possibility of proper prediction for a high-diastolic pressure group was 71.2%, predicting a normal-diastolic pressure group was 71.3%, and total Hit Ratio was 71.3%. Multiple regression analysis was performed to examine the association of systolic blood pressure with life style-related variables after adjustment for obesity, serum lipids, and demographic variables. First, the effect of demographic variable alone on the systolic blood pressure was statistically significant (p=.000) and adjusted $R^2$was 0.09. Adding the variable obesity on demographic variables resulted in raising adjusted $R^2$to 0.11 (p=.000) : therefore, the contribution rate of obesity on the systolic blood pressure was 2.0%. On the next step, adding the variable serum lipids on the obesity and demographic variables resulted in raising adjusted R2 to 0.12(P=.000) : therefore, the contribution rate of serum lipid on the systolic pressure was 1.0%. Finally, adding life style-related variables on all other variables resulted in raising the adjusted $R^2$to 0.18(p=.000) ; therefore, the contribution rate of life style-related variables on the systolic blood pressure after adjustment for obesity, serum lipids, and demographic variables was 6.0%. Multiple regression analysis was also performed to examine the association of diastolic blood pressure with life style-related variables after adjustment for obesity, serum lipids, and demographic variables. First, the effect of demographic variable alone on the diastolic blood pressure was statistically significant (p=.01) and adjusted $R^2$was 0.03. Adding the variable obesity on demographic variables resulted in raising adjusted $R^2$to 0.06 (p=.000) ; therefore, the contribution rate of obesity on the diastolic blood pressure was 3.0%. On the next step, adding the variable serum lipids on the obesity and demographic variables resulted in raising the adjusted $R^2$ to 0.09(p=.000) ; therefore, the contribution rate of serum lipid on the diastolic pressure was 3.0%. Finally, adding life style-related variables on all other variables resulted in raising the adjusted $R^2$ to 0.12 (p=.000) : therefore, the contribution rate of life style-related variables on the systolic blood pressure after adjustment for obesity, serum lipids, and demographic variables was 3.0%.

This study aims to examine how much Korean's family value orientations and gender role attitudes are different from those of U.S.A., Sweden, and Japan, and how demographic variables influence family value orientations and gender role attitudes across the countries. By using 2004 Korea General Social Survey data and 2002 International Social Survey Program family module, multiple regression analyses showed that Korean's family value orientations and gender role attitudes were much more traditional than those of U.S.A., Sweden, and Japan, even after controlling demographic variables. Furthermore, each country showed a distinct pattern in the impact of demographic variables on family value orientations and gender role attitudes. Among the demographic variables, age and marital status were statistically significant indicators of family value orientations for all the countries. However, gender, the year of education, and employment status effected on family value orientations only in some countries. The findings of this study showed that Korea was still traditional in terms of family value orientations and gender role attitudes, compared with U.S.A, Sweden, and Japan. Although family value orientations were more traditional in Korea than in the other countries, all the countries showed similar patterns of explaining mechanism in the effect of demographic variables on family value orientations. People who were men and married were likely to be more traditional than those who were women and unmarried. However, gender role attitudes showed interesting results. All the demographic variables were significant predictors of gender role attitudes for Korea, whereas only some of demographic variables were statistically significant indicators of gender role attitudes for other countries. That is, Korean society showed strong attitudinal differences on the basis of demographic variables. The implication of these differences was discussed.

This study examined the characteristics of the relationship of HOME, socio-demographic variables and children's intellectual and social abilities. The subjects of this study were 80 children at age four and their mothers. Instruments included inventory of home stimulation (HOME) and the inventory of socio-demographic variables and K-Binet scale, social naturation scale, and the social-emotional developmental rating scale. The results obtained from this study were as follows: 1. HOME, socio-demographic variables had a significant positive correlation (.37∼..66) with children's intellectual ability. 2. HOME, Socio-demographic variables had a significant positive correlation(.26∼..67) with children's social ability. 3. The variables that significantly predicted children's intellectual ability were play materials, breadth of experience and quality of langage environment. 4. The variables that significantly predicted children's social ability were play materials, economic status of the home and parent education. 5. The results of the causal model showed that the kind of variables that affected children's intellectual ability directly were direct stimulation, parent's education, indirect stimulation, and the emotional climate of the home. 6. The results of the analysis of the causal model showed that the kind of variables that affected children's social ability directly were direct stimulation, parent's education, economic status of the home.

Purpose: Despite the numerous studies on factors impacting pro-environmental behavior, actual studies analyzing a relationship between pro-environmental behavior and eco-friendly channels (e.g., local food market and farmers' market channel) usage behavior (visit and purchasing frequency) are rare. This study investigated the relationship between consumers with positive pro-environmental behavior and eco-friendly channels usage behavior. Research design, data and methodology: The study investigated the relationship between pro-environmental behavior and eco-friendly channels (local food markets and farmers market) visit behavior by analyzing data from the Korea Consumer Agency's 2021 Korea Consumption Life Index, with a focus on the pro-environmental index. Relationship between pro-environmental behavior and whether eco-friendly channels visit or not were analyzed. Demographic variables also influence eco-friendly oriented channels visit. Data analysis used hierarchical regression, firstly inputted pro-environmental behavior, and then demographic variables inputted, and finally pro-environmental behavior and demographics interactions as moderating variables inputted. Results: Consumer's with positive behavior towards pro-environment were indeed more likely to choose local food market and farmers' market compared to other consumers. Demographic variables also effect local food market visit. Some demographic variables moderate this relationship. The results, however, differed by channel type. Conclusions: Pro-environmental behavior is closely related to eco-friendly channels (local food market and farmers; market) visit.

The purpose of this study was to investigate family-demographic variables (sibling status, maternal attitude and demographic variables) affecting sibling sociability and peer sociability. Mothers and teachers of 291 kindergarten children were sampled. Specifically, 206 children of two-child families were studied by sibling status to investigate differences in sociability among siblings. Factor analysis, F-test, Pearson correlation, and multiple-analysis of variance were conducted. Sibling sociability and peer sociability were affected by sibling status. Maternal attitude and sibling sociability were positively correlated. The important family-demographic variables for both sibling sociability and peer sociability were maternal affective attitudes and sex of child.

This study investigated the relationship of demographic and psychological variables with job and family-related stress among 293 employed wives. We found that age, job types, working in weekend, and family cohesion significantly contributed to the explanation of job-related stress. We also found that job types, working in weekend, family adaptation, family cohesion, and employment motivation significantly contributed to explaining the variation of family-related stress. Job-related stress was more explained by demographic variables than psychological ones, whereas family-related stress was more explained by psychological variables than demographic ones. Practical implications of the current findings were discussed.

Ongoing demographic changes have brought about a substantial shift in the size and age composition of the population, which are having a significant impact on the global economy. Despite potentially grave consequences, demographic changes usually do not take center stage in many macroeconomic policy discussions or debates. This paper illustrates how demographic variables move over time and analyzes how they influence macroeconomic variables such as economic growth, inflation, savings and investment, and fiscal balances, from an empirical perspective. Based on empirical findings-particularly regarding inflation-we discuss their implications on macroeconomic policies, including monetary policy. We also highlight the need to consider the interactions between population dynamics and macroeconomic variables in macroeconomic policy decisions.

This study examined the characteristics of the relationship of HOME, sociodemographic variables and children's verbal ability at age four, five, six, Expecially this study investigated causal relationships amoong the variables which are supposed to affect children's verbal ability by children's age and sex. The subject of this study were 180 children and their mothers. Instruments included inventory of home stimulation(HOME), inventory of socio-demographic variables, inventory of the children's verbla ability. The results obtained from this study were as follows : 1. For the most part, HOME and socio-demographic variables had a significant positive correlation with children's verbal ability. 2. The variables that significantly predicted children's verbal ability differed according to children's age and sex. That is, play materials, breadth of experience and economic status of the home were predictive of boy's verbal ability at age four, while aspects of physical environment, breadth of experience were predictive at age five, fostering maturity and independence, parent's education were predictive at age six. And developmental stimulation and breadth of experience were predictive of girl's verbal ability at age four, while developmental stimulation, economic status of the home were predictive at age five, developmental stimulation and play materials were predictive at age six. 3. the results of the analysis of the causal model showed that the kind of variables that affected children's verbal ability directly differed according to children's age and sex. That is, indirect stimulation and direct stimulation affected boy's verbal ability directly at age four and five, while indirect stimulation and parent's education affected boy's verbal ability at age six. And indirect stimulation, direct stimulation, emotional climate of the home affected girl's verbal ability directly at age four, while direct stimulation, economic status of the home, indirect stimulation affected directly at age five, parent's education, indirect stimulation and direct stimulation affected girl's verbal ability at age six. 4. Another causal model of the HOME, socio-demographic variables affecting children's verbal ability showed that total HOME scores more significantly affected boys and girl's verbal ability directly than socio-demographic variables at all ages.
