This study focused on self-effects and spouse-effects that impact marital satisfaction in sex role stereotypes, work-family conflict and work-family enrichment. 95 double-income couples participated in this study, and the paired T-Test and multiple regression analysis were conducted. The result of the study showed that sex role stereotypes, work-family conflict, and work-family enrichment are not significant differences in husband and wife, but a husbands was significantly higher than wife in marital satisfaction. In the next step, we considered variables affecting marital satisfaction, and found a significant difference between husband and wife. Work-family enrichment positively affected the husband's marital satisfaction, while the wife's satisfaction was positively affected by the husband's sex role stereotype and negatively affected by her work-family conflict. This study suggests that marriage enrichment programs, the education of husband and wife, and couple counseling should consider individual effects and spouse effects.

Mirror symmetry for del Pezzo surfaces was studied in [3] where they suggested that the mirror should take the form of a Landau-Ginzburg model with a particular type of elliptic fibration. This argument came from symplectic considerations of the derived categories involved. This problem was then considered again but from an algebro-geometric perspective by Gross, Hacking and Keel in [8]. Their construction allows one to construct a formal mirror family to a pair (S, D) where S is a smooth rational projective surface and D a certain type of Weil divisor supporting an ample or anti-ample class. In the case where the self intersection matrix for D is not negative semi-definite it was shown in [8] that this family may be lifted to an algebraic family over an affine base. In this paper we perform this construction for all smooth del Pezzo surfaces of degree at least two and obtain explicit equations for the mirror families and present the mirror to dP₂ as a double cover of ℙ².

The aim of this study is to a study on the effects of fertile women on the low fertility in Korea. It is designed to research a model and established hypothesis with emphasis on major variables based on theoretical discussions. However, the result of the study is as follows. Firstly, this brought in delivery avoid phenomenon thus resulting in lower delivery phenomenon. The government should propose reasonable solutions to persuade female personal value and important elements of delivery rate at the same time. Secondly, Patriarchal stereotypes weighting household labor to female traditionally pressures working female with double burden as dual stance of work and family worsen the delivery will. Such atmosphere within a family generates female with an ability to get pregnancy to avoid marriage and delivery. Lastly, the research has pointed out the delivery support policy as most ineffective policy among government policies. To solve this problem, the government policy to recover delivery rate must be reviewed continuously and to be exercised immediately.

This study was undertaken to test to fit forms of the Engel curves to data. The comparisons were confined to the linear, semi-logarithmic and double-logarithmic forms. Data from the 1970-1987 Urban Household Economy Survey were used to estimate the Engel curves. The twelve categories of consumption expenditure were considered for investigation. Parameters of the Engel curves were derived from OLS and TSLS. In this paper the size of the family was used as the deflater. The results could be summarized as follows: 1. Comparing with the R2 of three foms, it could be concluded that, the linear form generally gave a better fit to data than the other forms did. Only for housing and clothing and foot wear, did the semi-logarithmic form give a better fit. Only for meals outside the home, fuel, light and water charges, and miscellaneous, did the double-logarithmic form give a better fit. 2. Comping with the income elasticities based on the alternative forms, it could be concluded that the differences between the estimates were since each form made different assumption as to the way in which elasticity varied. In general, the semi-logarithmic form gave the highest estimate and double-logarithmic form did the lowest estimate. The difference between semi-logarithmic and the other forms were greater than the those of linear and double-logarithmic form. 3. It was found that the income elasticity varied with the difinition of income used as an explanatory variable in Engel curves.

This study is focused on the amount of time spent on child care by mothers with preschool children with developmental disabilities. It is designed to find out how much time mothers spend taking care of their children and to identify related factors. The subjects of this study are 162 mothers of children with developmental disabilities residing in Seoul. The findings are as follows: First, mothers with preschool children with developmental disabilities spent 6 hours and 50 minutes per day caring for their children during weekdays and 6 hours and 10 minutes on weekend days. This is double the amount of time spent by the average mother with preschool children. Second, mothers spent much more time caring for their disabled children than they do for their children without disabilities. Third, determinants of a mother's time for caring their disabled child during weekdays were mother's employment, the number of children, and gender of the disabled child. On weekend days, determinants of mother's care time were the number of children and husband's help for childrearing.

Purpose: This study aimed to understand the essence of experiences of patients and family members during flexible visiting in an intensive care unit (ICU). Methods: This is a qualitative study using interviews with open ended questions. We used Colaizzi's method of phenomenological interpretation. Results: Flexible visiting in the ICU impacted the patients and their families in various ways. The following categories were extracted from the patients' experiences with flexible visiting: 1) the opportunity to feel the presence of the family and 2) the burden of unrestricted visiting. The following categories were extracted from the families' experiences with flexible visiting: 1) psychological comfort by convenience 2) being aware of health care professionals and critical care nursing in the intensive care unit, and 3) double trouble. Conclusions: These results showed that flexible visiting in the ICU affected the patients and their families positively and negatively. Therefore, nursing staff need to design psychological and social interventions that address the needs of patients and their families.

DNA-dependent protein kinase catalytic subunit (DNA-PKcs), a member of the phosphatidylinositol 3-kinase-related kinase family is a well-known player in repairing DNA double-strand break through non-homologous end joining pathway. This mechanism has allowed us to understand its critical role in T and B cell development through V(D)J recombination and class switch recombination, respectively. We have also learned that the defects in these mechanisms lead to the severely combined immunodeficiency (SCID). Here we highlight some of the latest evidence where DNA-PKcs has been shown to localize not only in the nucleus but also in the cytoplasm, phosphorylating various proteins involved in cellular metabolism and cytokine production. While it is an exciting time to unveil novel functions of DNA-PKcs, one should carefully choose experimental models to study DNA-PKcs as the experimental evidence has been shown to differ between cells of defective DNA-PKcs and those of DNA-PKcs knockout. Moreover, while there are several DNA-PK inhibitors currently being evaluated in the clinical trials in an attempt to increase the efficacy of radiotherapy or chemotherapy, multiple functions and subcellular localization of DNA-PKcs in various types of cells may further complicate the effects at the cellular and organismal level.
