Purpose: This study was to find out the correlations amongst family function. social support. and the perceived mother's love in the adolescents. Method: The study subjects were 171 adolescents of whom 43 were middle school students and 128 were high school students. The data consisted of general characteristics. family function. social support and perceived mother's love. The data were analyzed by frequency. mean. percentage. t-test. ANOVA and the Pearson's correlation using the SPSS statistical program. Result: 1. The mean score of the family function in the adolescents was 3.09 (maximum score: 5) and the mean score of cohesion was 3.23 and the mean score of adaptability was 2.94. There were significant differences in the family function according to grade and family type. 2. The mean score of the social support in the adolescents was 2.86 (maximum score: 5) and there was significant difference in the social support according to the fathers occupation. 3. The mean score of the perceived mother's love in the adolescents was 3.57 (maximum score: 5) and there were significant differences in the perceived mother's love according to grade. existence of the mother, the mother's occupation and adolescent's health state. 4. There were positive correlations between the family function, social support and the perceived mother's love. Conclusion: The above results suggest that there is a need to develop social support program for the adolescents in the low economic status. Further, a comprehensive program should be developed to relieve the problems of the adolescents considering the family function. social support and perceived mother's love.

Objective: This study examined the role of siblings with respect to living arrangements between married children and their parents. Previous studies have rarely considered the possibility that family context such as siblings may be associated with intergenerational residential proximity. Method: Using data from first wave of the Korean Longitudinal Study of Ageing (2006), I investigated if, among married children, their sibling characteristics may be associated with the probability of their coresiding with the parent(s), living nearby (within a 30-minute distance from parent(s) by public transportation), or living further away. Specifically, the total numbers of sisters and brothers, the numbers of siblings coresiding with the parent(s) and living nearby, their relative position in the sibling network (first-born son, later-born son, first-born daughter, later-born daughter), and sibship existence and gender configurations (only child, son with brother(s) only, son with sister(s) only, son with both brother(s) and sister(s), daughter with brother(s) only, daughter with sister(s) only, daughter with both brother(s) and sister(s)) were evaluated in the study. For data analysis, multinomial logit models with robust standard errors were estimated using the Stata mlogit procedure. Results: Results suggest that the probability of a married child living together with the parent(s), relative to living close by, was significantly higher the more sisters he or she has. Being a son, especially first-born son, was associated with a higher probability of intergenerational coresidence compared to near residence, respectively. Also, the numbers of siblings coresiding with the parent(s) and living in close proximity were linked to a higher risk of intergenerational coresidence and near residence. Supplementary analyses revealed that the last finding was held over and above the total number of siblings, their relative position in the sibling network, as well as sibling existence and gender configurations. Conclusion: Overall, the study findings indicate that sibling characteristics have significant impacts on intergenerational living arrangement. The influence of traditional patrilineal norm of intergenerational coresidence and a trend towards modified extended family have emerged when siblings characteristics are taken into consideration as determinants of intergenerational living arrangement.

In insurance, the surrender rate is an important variable that threatens the sustainability of insurers and determines the profitability of the contract. Unlike other actuarial assumptions that determine the cash flow of an insurance contract, however, it is characterized by endogenous variables such as people's economic, social, and subjective decisions. Therefore, a microscopic approach is required to identify and analyze the factors that determine the lapse rate. Specifically, micro-level characteristics including the individual, demographic, microeconomic, and household characteristics of policyholders are necessary for the analysis. In this study, we select panel survey data of Korean Retirement Income Study (KReIS) with many diverse dimensions to determine which variables have a decisive effect on the lapse and apply the lasso regularized regression model to analyze it empirically. As the data contain many missing values, they are imputed using the random forest method. Among the household variables, we find that the non-existence of old dependents, the existence of young dependents, and employed family members increase the surrender rate. Among the individual variables, divorce, non-urban residential areas, apartment type of housing, non-ownership of homes, and bad relationship with siblings increase the lapse rate. Finally, among the financial variables, low income, low expenditure, the existence of children that incur child care expenditure, not expecting to bequest from spouse, not holding public health insurance, and expecting to benefit from a retirement pension increase the lapse rate. Some of these findings are consistent with those in the literature.

This study aims to determine the factors that affect dividends initiation by initial public offering firms in Malaysia. The ownership structure is examined from a corporate governance theoretical perspective in order to evaluate the impacts of managerial, institutional, and family ownership on the dividend's initiation decision of IPO firms. This study employs a quantitative pooled cross-section of 372 Malaysian IPO companies active during the period of 2002-2013. The number of firms that went public each year varies, thus the pooled cross-section data takes place in this case rather than the panel data. The logistic model was employed to test the proposed hypotheses. The results revealed that the presence of institutional investors in the ownership structure make it more likely for IPO firms to initiate dividends. On the contrary, the presence of a family ownership structure in IPO companies as the controlling shareholder makes these companies less probable to initiate dividends. Managerial ownership was found to have no effect on the decision of initiating dividends by IPO firms. The findings of this study suggest that the existence of institutional and family ownerships are agency cost mitigators, as these ownership types could prompt IPOs firms to initiate dividends to overcome the agency conflicts.

The aim of this paper is to present theorems on the exitence of zeros for mappings defined on convex subsets of topological vector spaces with values in a vector space. In addition to natural assumptions of continuity, convexity, and compactness, the mappings are subject to some geometric conditions. In the first theorem, the mapping satisfies a "Darboux-type" property expressed in terms of an auxiliary numerical function. Typically, this functions is, in this case, related to an order structure on the target space. We derive an existence theorem for "obtuse" quasiconvex mappings with values in an ordered vector space. In the second theorem, we prove the existence of a "common zero" for an arbitrary (not necessarily countable) family of mappings satisfying a general "inwardness" condition againg expressed in terms of numerical functions (these numerical functions could be duality pairings (more generally, bilinear forms)). Our inwardness condition encompasses classical inwardness conditions of Leray-Schauder, Altman, or Bergman-Halpern types.

A special class of exponential dispersion models is the class of Tweedie distributions. This class is very significant in statistical modeling as it includes a number of familiar distributions such as Gaussian, Gamma and compound Poisson. A Tweedie distribution has a power parameter p, a mean m and a dispersion parameter 𝜙. The value of the power parameter lies in identifying the corresponding distribution of the Tweedie family. The basic objective of this research work resides in investigating the existence of the implicit estimator of the power parameter of the Tweedie distribution. A necessary and sufficient condition on the mean parameter m, suggesting that the implicit estimator of the power parameter p exists, was established and we provided some asymptotic properties of this estimator.

The purpose of this study is to understand a ChoSun-jok female domesic worker's experience in a Korean home. This study adopted hermeneutic phenomenological method which was developed by van Manen. The participant for this study was a ChoSun-jok woman who had worked as a care-giver and housekeeper in Korean home for more than 2 years. She missed the time when she was raising her own daughter and son and expected the time that her family would be together. So, her present time wears away for her stable future in Korea which give an opportunity to make a good money. Also, she realized that she was a marginal existence : it meant she was neither a family member nor truly worker. She nursed the Korean children and did for the Korean family for money but wanted to be treated as a family member like a grandmother who could be honored about what she had done for the family. She felt that she was disregarded from the family when she miscommunicated with them because of the difference between cultures. She anticipated that she was appreciated for being here in the Korean home.

The purpose of this study was to investigate the distribution and correlation of stroke risk factor according to age with stroke patients. This study was based on clinical data registered in Daejeon Oriental Medical Hospital from November 2006 to December 2010. Study subjects consisted of 779 patients with stroke within 1 month and they were classified according to age and existence of past history such as hypertension, diabetes mellitus, ischemic heart diseaseand stroke family history. Stroke family history was distributed differently according to age unlike past history and in their 50's showed a particularly high rate. There was not statistically significant correlation between stroke family history and past history except for only between stroke family history and diabetes mellitus in the patients in their 80's and more. There was statistically significant correlation between hypertension and diabetes mellitus and especially in the patients in their 60's and 70's. There was statistically significant correlation between hypertension and ischemic heart disease and especially in the patients in their 80's and more. There was statistically significant correlation between diabetes mellitus and ischemic heart disease in the patients in their 60's. There was statistically significant correlation among hypertension, diabetes mellitus and ischemic heart disease, but stroke family history and past history had independence, so management and research for this subject should be required further and further.

Since 1998 when economic assistance from IMF started, the empirical research on the effects of unemployment and drastic income loss on psychological functioning among the unemployed as well as their family members has increased. These studies have found that unemployment and drastic income loss following unemployment have significant negative influence on the psychological outcomes such as anxiety and depression of the unemployed and their family members. Studies have also focused on the role of social support in this process, and reported that depending on the levels of received social support, unemployment and income loss have differential effects on the psychological aspects of the unemployed. However, these studies have several weaknesses. First, most of the related studies employed the data which were collected from limited regions of the country, which imposes limitations on the scope of the generalizability of research findings. Second, the main independent variables used in these studies were mainly unemployment or income loss, which ignore the psychological evaluation by the employed of their family financial situations. Third, in analyzing the moderating effects of social support, most studies have focused mainly on showing the existence of moderating effects by social support. Consequently, the nature and role of social support remained unanalyzed and left to speculations. The purpose, of this study is to examine the effects of economic pressure experienced by family heads who were unemployed and to analyze the moderating role of social support based on a nationally representative sample. The findings showed that economic pressure has negative influence on anxiety and depressive feelings among the unemployed, and that the effect of economic pressure on depressive feelings were substantially higher among those who have received lower levels of social support from family members than that among those with higher levels of family support.

Let X be a closed convex subset of a Banach space B and T:X.rarw.X a lipschitzian rotative map, i.e., such that ∥Tx-Ty∥.leq.k∥x-y∥ and ∥T$^{n}$ x-x∥.leq.a∥Tx-x∥ for some real k, a and an integer n>a. We denote by .PHI. (n, a, k, X) the family of all such maps. In [3], [4], K. Goebel and M. Koter obtained results concerning the existence of fixed points of T depending on k, a and n. In the present paper, the main results of [3], [4] are so strengthened that some information concerning the geometric estimations of fixed points are given.
