Every one hopes for the strong or healthy families and happy society, The Healthy Families Act legislated on February 9, 2004, and three centers were appointed to perform as a model, before the law has been in force from January 1, 2005. The major services or programs at the Center performed last year were as follows; educational programs, counseling for prevention of family problems, and cultural events for strengthening the family functions. This study presented the general situations of Seoul Yongsan-gu Sookmyung Women's University Center for Healthy Families last year, evaluated the product of cultural events or programs, and proposed better ideas for managing cultural services or programs. In 'the division of Home Culture', the community networks were established, and diverse events or programs provided drew high satisfaction among attendants. In the future, some services or programs at Seoul Yongsan-gu Sookmyung Women's University Center for Healthy Families hoped to be helpful and made a basis for activating services or programs for other centers.

Convergence of an implicit iterative process is investigated for nonexpansive mappings. Strong and weak convergence theorems of common fixed points of two finite families of nonexpansive mappings are established in the framework of Banach spaces.

In this paper, we introduce a new three-step iterative scheme for three finite families of nonexpansive mappings in hyperbolic spaces. And, we establish a strong convergence and a ∆-convergence of a given iterative scheme to a common fixed point for three finite families of nonexpansive mappings in hyperbolic spaces. Our results generalize and unify the several main results of [1, 4, 5, 9].

본 논문에서는 강력한 의사난수 함수 관점에서 안전한 tweakable 전단사 함수 패밀리를 이용하여 연관키에 안전한 전단사 함수 패밀리를 설계할 수 있음을 보인다. 이를 이용하여 현재까지 알려진 것 중에 가장 빠르면서 연관키 공격에 안전한 전단사 함수 패밀리를 구성한다. 또한, 의사난수 함수 관점에서 안전한 적당한 유형의 함수 패밀리를 이용하여 연관키 공격에 안전한 전단사 함수 패밀리를 구성할 수 있음을 보인다. 이는 기존의 안전성이 증명된 MAC 알고리즘을 이용하면 연관키 공격에 안전한 스킴을 구성할 수 있음을 나타낸다. 끝으로, 본 논문에서는 연관키 공격에 대한 여러 안전성 개념(indistinguishability, non-malleability)을 정의하구 그들 사이의 관계를 살펴본다.

The purpose of this research was to assess gender differences in the processes of intergenerational transmission of marital instability. This study revealed gender differences in the intergenerational transmission of marital instability. The fit indices suggest that the hypothesized model fit better for the female sample. Parental divorce marital quality and marital commitment were significant predictors of marital instability for both genders. Parental divorce was a strong predictor of marital quality for women only. While the path between age difference and marital quality for females was strong the same association disappeared for their male counterparts.

Boente and Fraiman [2] studied robust nonparametric estimators for regression or autoregression problems when the observations exhibit serial dependence. They established strong consistency of two families of M-type robust equivariant estimators for $\phi$-mixing processes. In this paper we extend their results to weaker $\alpha$$alpha$-mixing processes.

Since 1990, South Korean children living in relative poverty have increased whereas those living in absolute poverty have decreased until 2002 and then the decrease remained somewhat stagnant. A substantial body of research proposed a strong relations between child poverty and low quality well-being of the child. Poor children, in comparison to those of more affluent families, are more likely to have health, behavioral, social, and emotional problems. They are also more likely to grow up in families that provide less cognitive stimulations which, in turn, can negatively affect their cognitive and academic attainments. The present paper highlights the trends and the consequences of child poverty and suggests policy approaches based on the premise of decreasing poverty of low-income children and their families.

Using survey data collected from 275 adolescent children of widowed or divorced single mother families, this study investigated the characteristics of family coping resources, including individual, financial, social, and mother-child relational resources and their effects on the psychological wellbeing of these adolescents. After controlling background variables of the family, higher depression among adolescents was associated with low grade point average, mother's high exposure to negative experiences after loss of father, low attachment to mother, and low sense of self-control. Furthermore, higher grade point average, strong attachment to mother, and high self-control in problem solving were factors predicting higher self-esteem of adolescents. Social network resources were not related to the psychological well-being of the adolescents. Discussion included recommendations for future research. Implications for policy and parent-child relations were discussed with a view to enhancing family functioning of adolescents in single-mother families.

The purpose of this study is to examine the regional differences of 0-12 aged children's environment based on their parents' socioeconomic class and on the character of the settlement. One thousand and two hundred households were investigated and the results are as follows. It is revealed that families in low socio-economic class are more likely to be exposed to noise and home crowdedness. Families living in spontaneous settlement are deprived of natural light and the roads to their homes are steep and narrow. Low income families face a housing affordability crisis. Most of them pay housing rent on monthly basis. The basic infrastructure of low income neighborhood is lacking convenient facilities like shopping centers, public transportation systems, banks, public parks, and libraries. This lack of facilities is more severe in spontaneous settlement. Instead, bars and taverns are located in their neighborhood. Accessibility to parks and resource centers is an important factor that makes both middle and low income families consider their neighborhood to be positive and this condition is counted better in social housing area than in spontaneous settlement. On the contrary, social networks like friends and relatives are strong in spontaneous settlement and families in poverty value these relationships. Such networks are weak in social housing area and this difference is not related to their residential period. Low income families living in social housing area are more pessimistic about their future and this view might result from their counterpart middle class neighbors and the weak social networks.

Urben wage workers' education expenditure among different social classes from 1979 to 1993 has been compared. Eduction expenditure has increased much more than that of income resulting from income increase and government policy. Education expenditure gaps among social classes have showed to be an increasing trend although the ratio of education expense to the income has increased among low class families. Average income elasticity was 1.1 and this result showed that education expense was luxury good. Income elasticity of education expense among low class families have fluctuated more than any other classes resulting from construction business cycle and housing rent increase. Average Gini coefficient was 0.38 and turned out to be highest among 9 household expenditures, however it was in the trend of improvement from 81. But from 91 Gini Coefficient went up high again. Main reason for this increase was due to high social class families' eucation expenditure increase. Government's strong policies to enhance equality level of education opportunity and to support low class families are urged.
