Loan amount of housing mortgage is composed of various factors. This study paper studies focuses on estimating the determinants of a loan amount of housing mortgage. The region for analysis consist of seven groups, that is, metropolitan city (such as Busan, Daegu, Incheon, Gwangiu, Daejeon, Ulsan.) and Seoul. Analyzing period be formed over a 45 time points(2007. 01.~ 2010. 09). In this paper the dependent variable setting up loan amount of housing mortgage, explanatory(independent) variables are composed of the consumer price index, unemployment rate, average monthly household income per household, expenditure rate of health care, composite stock price index and overdue rate of household loans for commercial bank. In looking at the factors which determine loan amount of housing mortgage, evidence was produced supporting the hypothesis that there is a significant positive relationship between the consumer price index and unemployment rate. The study also produced evidence supporting the view that there is a significant negative relationship between expenditure rate of health care. The study found that average monthly household income per household, expenditure, composite stock price index and overdue rate of household loans for commercial bank were not significant variables. The implications of these findings are discussed for further research.

Objectives: The aim of this study was to examine factors influencing depressive symptoms among married working women using the dataset of the Korean Longitudinal Survey of Women and Family (KLoWF 7th). There were 1,030 subjects. Methods: A multiple regression model was used to study the factors influencing depressive symptoms among married working women. Results: The authors found a negative relationship between satisfaction with spouse household-labor (b=-0.606, p=0.022) and depressive symptoms among married working women, a negative relationship with spouse (b=-0.237, p<0.001) and a negative spousal perception of working (b=-0.709, p=0.045), a positive relationship with excessive working hours (b=0.397, p=0.027), a positive relationship with temporal oppression on workload (b=0.422, p=0.002), and a positive relationship between workplace discrimination (b=0.053, p=0.046) and depressive symptoms among married working women. Conclusions: This study suggests that family life and working environments are important factors for depressive symptoms in married women workers. The findings of this study will be helpful to policymakers to design plans to decrease depressive symptoms among married working women.

This study used data from the 3rd and 11th year of the Korean Welfare Panel to evaluate the effects of the Long-Term Care Insurance(LTCI) system on the consumption and expenditure of LTCI users' households. The study consisted of program group using LTCI and control group not using. Chi-square and t-test were used for the characteristic differences among the groups, and the difference of consumption expenditure was identified by multiple regression analysis. As a result, LTCI had a statistically significant effect on the health care costs of LTCI users' households, resulting in an increase in health care costs(${\beta}=3.06$). However, there was no statistically significant effect on the total cost of living, basic cost, education cost, and recreation/entertainment cost. Therefore, in order to show the effect of LTC system, we should try to reduce of self-pay and improve the contents and quality of the service of the LTC system.

Anti-glare (AG) coating films are applied to various display fields such as liquid crystal displays, LED lighting, and touch panels. In this study, micrometer-sized silica particles were added as fillers in the UV-curable coating solutions to provide anti-glare effect. During this process, the effects of the particle size, content, stirring time, and mixing ratio of silica particles of different sizes were investigated on the haze values and visible light transmittance of the coating films. As a result, as the size of the silica particles increased and the content of the silica particles increased, the haze values increased, but the visible light transmittance decreased. On the other hand, the stirring time did not significantly affect the haze value and transmittance of coating films. In addition, as the mixing ratio of large-sized silica particles increased, the haze value increased, but on the contrary, the visible light transmittance decreased.

This study was attempted to identify factors for managing hyperlipidemia in middle-aged adults. The research method is a secondary analysis study analyzing the 2018 data from the Korean Medical Panel Survey. The subjects of the study were 622 adults aged between 40 and 65 who were diagnosed with hyperlipidemia. As a result of the study, it was found that there was a correlation between the level of education and the presence or absence of hyperlipidemia management (𝒳²= 7.285, p = .026), and that there was a correlation between the subject's subjective health status and the presence or absence of hyperlipidemia management (𝒳²= 7.295, p =.026). Middle age is a time when the physical aging process begins in earnest, and there is a high possibility of developing chronic diseases, and hyperlipidemia is an early disease that causes chronic diseases. Accordingly, active health management is necessary, and in particular, the development of differentiated programs for hyperlipidemia management tailored to the subject's education level and health status is required.

Purpose: Establishment of an appropriate protocol for breast magnetic resonance imaging (MRI) in the study of image quality standards to enhance the effectiveness of medical image information exchange, which is part of the construction and activation of clinical information exchange for healthcare informatization. Materials and Methods: The recommended protocols of breast and MRI scans were reviewed and the questionnaire was prepared by a responsible researcher. Then, a panel of 9 breast dedicated radiologists was set up in Korea. The expert panel conducted a total of three Delphi agreements to draw up a consensus on the breast MRI protocol. Results: The agreed breast MRI recommendation protocol is a 1.5 Tesla or higher device that acquires images with prone position using a breast dedicated coil and includes T2-weighted and pre-contrast T1-weighted images. Contrast enhancement images are acquired at least two times, and include 60-120 seconds between images and after 4 minutes. The contrast enhancement T1-weighted image should be less than 3 mm in thickness, less than 120 seconds in temporal resolution, and less than $1.5mm^2$ in-plane pixel resolution. Conclusion: The Delphi agreement of the domestic breast imaging specialist group has established the recommendation protocol of the effective breast MRI.

This study aimed to analyze characteristics and factors affecting of depression by households type of elderly with disabilities. Data were analyzed using chi-square test, logistic regression analyses according to the PSED. Data were 608 individuals. First, The one-person households group showed significantly female, non-capital, severe disorder, lower health status, lower economic level, higher help for daily life, higher experience of discrimination, lower satisfaction with relationship, lower participation in social activities. Second, Factors affecting depression included experience of discrimination, participation in social activities. Multi-person group included gender, occupied area, health status, economic level and one-person group were help for daily life. In order to reduce depression, it is necessary to reduce experience of discrimination, improve awareness of disability, health care, economic supports and so on. This study is meaningful in that it classifies households types. In the future, there is a need to longitudinal studies.

Purpose: This study was to identify health-related quality of life of Korean young adults and elderly with multimorbidity and to examine factors influencing their health-related quality of life. Methods: Health-related quality of life was measured by the Korean version of the EQ-5D. Using a descriptive study, the study incorporated a secondary analysis of the Korean version of the EQ-5D data from the 8th wave of the Korea Health Panel Survey in 2013. Selected demographic data and the Korean version of the EQ-5D were analyzed using ${\chi}^2$-test, t-test, ANOVA and multiple regression analysis. Results: Education, drinking, type of health insurance, and number of chronic disease significantly affected the health-related quality of life in the young adults with multimorbidity. Educational level, occupational type, drinking, physical activity, number of chronic disease, unmet healthcare need and the type of multimorbidity significantly affected the health-related quality of life in the elderly with multimorbidity. Conclusion: The factors influencing health-related quality of life were different for young adults versus elderly with multimorbidity. Therefore, there is a need for age-specific health care programs that may improve health-related quality of life of adults with multimorbidity.

The health-related quality of life data are commonly skewed and bounded with spike at the perfect health status, and the variance tended to be heteroscedastic. In this study, we have developed a prediction model for EQ-5D using linear regression model, beta regression model, and extended beta regression model with mean and precision submodel, and also compared the predictive accuracy. The extended beta regression model allows to model skewness and differences in dispersion related to covariates. Although the extended beta regression model has higher prediction accuracy than the linear regression model, the overlapped confidence intervals suggested that the extended beta regression model was superior to the linear regression model. However, the expended beta regression model could explain the heteroscedasticity and predict within the bounded range. Therefore, the expended beta regression model are appropriate for fitting the health-related quality of life data such as EQ-5D.

This study investigated the patterns of transition of consumption patterns in Korean households in 2010 and 2017, and the impact of the life cycle on the transition of consumption patterns between the two time points. Using information on 4,717 households from the 2010 and 2017 data of the Korean Labor Panel Survey, we examined the effect of the family life cycle on changes in consumption patterns. The results of the latent transition analysis on the change in consumption type showed that the change in consumption type between the two points of time at the household level was relatively active. The logistic regression models reported that the transition of consumption type varies depending on the life cycle, such as changes in marital status, birth and independence of children. These results provide the implication that it is necessary to consider from the perspective of the family life course how the transition between their consumption types occurs when the government establishes consumption policies and companies set marketing target groups.
