In this study, I analyzed determinant factors of mutual fund return. The samples was distributed into three types according to the ratio of included stocks in funds. The proxies of mutual funds were set up three ways(returns of fund). As a result of the analysis, I found that growth positively affect to fund return, abnormal return and adjusted abnormal return in all samples. While, according to three types of sample, expected and unexpected fund cash flows had differently effect on fund return. Inferentially, it seemed that the ratio of included stocks in fund was the cause of that. But price pressure hypothesis are not supported. In conclusion, it was not found the possibility of stock market disturbance in this analysis.

Slope failures are one of the significant disasters which causes lots of human casualties and huge financial losses every year. Previous researches on the slope failure have indicated that most accidents are closely related to the pore water pressure in the slope due to rainfall during the rainy seasons or stormy weather conditions. It would be therefore appropriate to consider the effect of pore water pressure in the design of slopes. As the existing slopes are generally reinforced by plants and other slope protecting measures, their boundary conditions are highly complicated. In this paper an attempt to develop a new modeling and analysis technique of slopes is proposed by including pore water pressure and adopting the coupled finite element method. Non-reinforced and reinforced slope models are considered. Representative analysis showed that the numerical modeling considering pore water pressure is appropriate in slope stability analysis. Flow behavior in the slopes is identified for various hydraulic boundary conditions. It is also shown that the effect of pore water pressure on slope stability is significant.

Nowadays heat exchangers that have been applied for freon refrigerating systems, a shell and tube type condenser, but because of their large size, large space for installation and more amount of refrigerants are needed. Therefore, in this study, we will find the most suitable operating condition through the comparison of performance between the shell & tube type and shell & disk type heat exchanger with R22. The experiments are carried out for the condensing pressure of refrigeration system from 1500kPa to 1600kPa and for the degree of superheat from 0 to $1^{\circ}C$ at each condensing pressure. As a result of experiment, if the shell & disk type heat exchanger is applied for R22 refrigerating systems, minimized input of refrigerants and space required for installation will be secured, which will have a great contribute to financial improvement for industry.

Objectives : The aim of this study was to analyze the influence of foreign and institutional investors in the pharmaceutical industry on R&D investments. Methods : The empirical analysis was done for the years 2009 to 2013 which examined the period after the influence of the financial crisis. Financial statements and comments in general and internal transactions were extracted from the TS-2000 of the Korea Listed Company Association. STATA 12.0 was used as the statistical package for the panel analysis. Results : The results show that the shareholding ratio of foreigner investors turned out to have a statistically significant influence on R&D investment. No statistical significance was found in the shareholding ratio of institutional investors. Conclusions : The findings of this study, which indicate that a higher shareholding ratio of foreigner investors leads to greater R&D investment, indicate that foreign investors directly or indirectly impose pressure on a manager to make R&D investments for the long-term.

The purpose of this study was to examine the career-interrupted lives of highly educated career-interrupted women. The participants were 11 women in their thirties who had graduated from university graduated and had a child. We collected the qualitative data using a focused group interview. The results of this study can be summarized as follows. First, in personal histories of the career-interrupted women, there were marriages and births, difficulties with child care, priority placed on the family, pressure to retire, and an absence of a layoff system related to births and child care. Second, with regard to their interrupted lives, while there was comfort and an absence of work-stress, there was child care stress, financial stress, anxiety due to career uncertainty, a loss of the social self, depression, emptiness, low self-esteem, dependence on husbands, regret, conflict in career choices, and envy of childcare support. Third, their reasons for seeking reemployment included the financial benefits, increased independence, self-realization in their job, hope for a stable job, self-management, and hope for a social network.

This research analyzes factors of family life adjustment in mixed-culture families through a focus group and individual interviews with nine mixed-culture couples eighteen people who live in city C. First, the reason that women of other cultures wants to marry Korean men is because they find it a good opportunity, as they expect that Korean husbands will take responsibility of their family. On the other hand, Korean men also expect that they would have some similarities to each other. Also, in southeastern Asian men have more freedom than women to choose an international marriage in Southeastern Asia. Second, mixed-culture couples in everyday life are affected by communication problems, cultural differences, natural environment, financial situation, male -dominant attitude, self-adjustment pressure, house-work role and financial support from their own country. Third, wives from other cultures ask for social support to adjust in Korea and make a healthy family. These women can be important, as they have their own role in the family even though they may be far from their mother in law's strong expectation in how well she can adopt Korean culture.

The term "catastrophic health expenditure" means assessing the extent to which medical costs cause financial hardship for households. The aim of this research is to analyze the percentage of households that faced severe financial strain due to medical expenses from 2006 to 2021. This was achieved by utilizing data obtained from the National Survey of Tax and Benefit (NaSTaB), Korea Health Panel (KHP), and Households Income and Expenditure Survey (HIES). A trend analysis was conducted to examine the percentage of households that experienced catastrophic healthcare expenses. The households that experienced the catastrophic health expenditure was 2.49% in 2021 using the NaSTaB data. The trend analysis yielded a statistically significant result, indicating a decreasing trend (annual percent change [APC], -4.79; p<0.0001) in the proportion of households facing catastrophic health expenditures. Also, the results of the 2019 KHP and the 2021 HIES showed 1.09% and 2.44% for the households that experienced catastrophic health expenditure. The trend was increased according to the KHP (APC, 0.55; p=0.0004) and the HIES (APC, 7.04; p<0.0001). As a result, this study proposes that sustained attention and further interventions are necessary to ease the economic pressure caused by catastrophic health expenses, particularly for low-income households.

The purpose of this study was to explore the effects of family life stress and family values on marital stability among middle-aged couples. The subjects included a total of 302 men and women aged 45-64 who had been married for more than 20 years and were living in Seoul. The collected data were statistically analyzed with the SPSS 21.0 Package. First, Cronbach's alpha was calculated to measure the reliability of the scale that assessed the variables of the research model. Then, mean and standard deviation were calculated to determine the degrees of family life stress, family values, and marital stability among the subjects. Finally, a hierarchical multiple regression analysis was performed to identify factors that affected the subjects' marital stability. The results revealed that the level of family life stress in middle-aged married men and women was slightly higher than the mean value. Of all the sub-scales of family life stress, the subjects were found to experience the most stress from factors related to financial pressure, followed by family relationships, a sense of loss within a family, and work-family compatibility. Therefore, financial problems were one of the critical stressors for middle-aged married couples. Also, for this demographic, the levels of family values and marital stability were higher than the medians. The factors affecting marital stability in middle-aged couples were identified to be family relationship stress, financial stress, subjective economic status, family values, stress related to work-familycompatibility,religion,andage.Thedegreeofmaritalstabilitywashigherinmiddle-agedcouplesa stheirstresslevelsfromfamilyrelationshipsandfinancialproblemswerelower.Moreover,thehigherthes ubjectiveeconomicstatusandthemoretraditionalthefamilyvalues,thehigherthedegreeofmaritalstabili ty.Finally,marriedcoupleswhowerereligioushadalowerlevelofstressfromwork-family compatibility, and the younger the couples, the higher the degree of marital stability.

This study explores the trends of social security expenditures after financial crisis in welfare states. For the purpose, this study analyzes changes in social expenditures during 1980~2003 in 22 OECD countries. The results show that average total social security expenditure(as a percentage of GDP) among the 22 countries increased from 18.0% in 1980 to 22.3% in 2003. Compared to sharp increases during the great expansion period of the welfare state before 1980s, the increase in social expenditures after 1980s is substantially weakened. The slowdown in the increases of social expenditures is remarkable in the social democratic welfare states where social expenditures have already reached a high level. On the other hand, social expenditures are considerably increased in the lagged welfare states such as South European countries and Japan. As a result, the cross-national difference in social expenditures has continuously decreased. These findings suggest that financial crisis is a key factor of welfare-state reorganization. Countries where social expenditures are in high level need more reforms under the pressure of financial deficits. Since 1980s, they have tried various reforms especially in pensions and unemployment benefits. Facing new and increasing demands for social security as well as financial limitations, the welfare state needs major reforms in the social security system to increase effectiveness/efficiency of existing programs and to iron out priorities among programs.
