The purpose of this study was to examine the effects of the environmental factors and the family structure on the academic achievements of their children. Among various environmental factors, the family income, the affective relationship between mother and child, and the mother's educational involvement are considered. Total of 164 mothers with children attending elementary school completed the structured questionnaires. The degree of educational involvement of single mothers was lower than that of mothers of both parents families. In order to analyze factors that affect children's academic achievement, the path regression was performed. The family income and the mother-child affective relationship were found to have indirect effects on the academic achievements of elementary school students through maternal involvement in their children's education.

This study invesitgated the mediation effect of self-resilience on the relationship between perceived family strength and adolescents' level of adjustment at school. Participants were 479 elementary and middle school students from Daejeon. Data were analysed by SPSS 12.0 and Structural Equation Modeling with AMOS 5.0. Results were as follows: Firstly, family strength gives a direct effect on adolescent's school adjustment. Secondly, family strength is mediated by self-resilience on adolescent's school adjustment. Thirdly, significant differences in the path coefficients of the two groups were not found. These results indicate that we should expand the subjects of family and juvenile welfare, including general adolescents and general families, in order to improve family strength. In addition, programs such as the personal relationship and confidence elevation programs should be enacted to support elementary students' self-resilience.

The purposes of this study are to define the family life events as a input factor of system model and to understand structural characteristics of the family life events in the modern multilateral society have and orientation of the management system leads a satisfactory life. This study attempted through the relation of cause and effect among the components of management system by Deacon & Firebaugh systems theory. The findings of this study are as follows: 1) As for the influence of family life events on the orientation of home management behavior the influential family life event on overall the orientation of home management behavior was social problem of family members($\beta$= -128). 2)Family life events which have influence on the family life satisfaction were financial problem and trouble with husband members problems demand for housework and everyday affairs. 3) The subdivison of home management behavior which influenced on the overall family life satisfaction were communication and decision originality the use of resources and the flexibility of plan. 4) Results of path analysis revealed that relation of cause and effect out of family life events resources the patterns of home management behavior and family life satisfaction the family life events made the family life satisfaction higher because they had negative effect on the family life satisfaction directly but changed total effect into positive one by family management behavior.

We present a statistical model for the path loss of ultrawideband (UWB) channels in indoor environments. In contrast to our previously reported measurements, the data reported here are for a bandwidth of 6GHz rather than 1.25GHz; they encompass commercial buildings in addition to single-family homes (20 of each); and local spatial averaging is included. As before, the center frequency is 5.0GHz. Separate models are given for commercial and residential environments and, within each category, for lineof sight (LOS) and non-line-of-sight (NLS) paths. All four models have the same mathematical structure, differing only in their numerical parameters. The two new models (LOS and NLS) for residences closely match those derived from the previous measurements, thus affirming the stability of our path loss modeling. We find, also, that the path loss statistics for the two categories of buildings are quite similar.

Dubins showed that any shortest path of a car-like robot consists of exactly three path segment which are either arcs of circles of radius r(denoted C), or straight line segments(denoted S). Possible six types classified into two families, i.e. CSC and CCC. CSC includes 2 types(LRL and RLR) and CSC includes 4 types(LSL, RSR, LSR, RSL). This paper proposes new formulae for CSC family to find the shortest smooth path between the initial and final configurations of a car-like robot. The formulae is used for finding connection points explicitly between C\longrightarrowS and S\longrightarrowC which are necessary for real applications. The formulae have simple forms mainly because they are transformed into origin of their original coordinates of initial and target configuration, and derived from a standard forms which are a representative configuration of LSL and LSR type respectively. The proposed formulae, which are derived from the standard forms, are simple and new method.

Purpose: This study was to test a theoretical model examining the relationships among social support, illness demands, marital adjustment, family coping and family functioning in couples more than three years after breast cancer diagnosis. Methods: A causal modeling methodology was used to test the specified relationships in the recursive theoretical model. A total of 60 couples with breast cancer were recruited from January to April 2005. Five standardized questionnaires were used to measure the theoretical concepts: social support (ISSB), illness demands (DOII), marital adjustment (DAS), family coping (F-COPES), and family functioning (FACESII). Results: Path analysis results from the wives and the husbands revealed different patterns. Three hypotheses were supported in the wife model as predicted: social support and family coping, family coping and family functioning, and social support and marital adjustment (trend). Five hypotheses were supported in the husband model as predicted: social support and illness demands, also social support and marital adjustment, illness demands and marital adjustment, marital adjustment and family coping, and family coping and family functioning. Conclusion: This study provides valuable information for developing various interventions with social support for improving family functioning of breast cancer couples in the middle adaption stage (more than three years after diagnosis).

Purpose: This study aimed to understand the mechanisms of decision regret and stress of family surrogates' end-of-life decision making using an exploratory path model. In particular, the research identified the direct effects of perceptions of uncertainty and effective decisions on decision regret and stress, and examined the indirect effects of being informed, having clear values, and being supported for decision regret and the stress of end-of-life decision making through the mediating variables of perceptions of uncertainty and effective decisions. Methods: Data were collected from 102 family surrogates who had participated in end-of-life decision making for patients with terminal cancer in a tertiary hospital. Results: Perception of effective decisions was a significant direct predictor of decision regret, and uncertainty was a significant predictor of stress among the participants. Being informed, having clear values, and being supported had a significant indirect influence on decision regret through the perception of effective decisions among family surrogates. However, only having clear values had a significant indirect influence on stress through the perception of uncertainty. The model explained 63.0% of decision regret and 20.0% of stress among the participants and showed a good fit with the data, ${\chi}^2=12.40$ (df=8, p=.134), TLI=.97, and RMSEA=.07. Conclusion: Nurses can support family surrogates in end-of-life decision-making processes to decrease their decision regret by providing information about end-of-life care choices, clarifying personal values, and supporting the decision-making process, and to relieve their stress by facilitating the clarification of personal values.

The study explored the work-life balance of three dual-earning couples using the household economics approach according to the hermeneutics paradigm. Three families were analysed. The couples were interviewed individually with a non-structural interview guide about their work history and life history, and with a semi-structured interview and structured questionnaire about their work hours, childcare practice, husband-wife relation, household income and expenditure, and daily and weekly schedule. The results revealed the different paths and various strategies to adjust work-life balance among the cases. Strategies were discussed to facilitate changes in labor market policy, childcare policy, working place culture and family's daily life planning.

The purpose of this study was to investigate whether attachment to primary caregivers and family interaction affect rural children's social competence through self-regulation ability. To achieve this, a survey was conducted with 345 students aged 11-13 attending elementary schools in a rural area of Gyeongsang Province. Data were analyzed using descriptive statistics, Pearson correlation analysis, and path analysis using the AMOS 23.0 program. The main result was that rural children's self-regulation had an indirect effect on attachment with primary caregivers and family interaction through social competence. The findings of this study will contribute to designing a variety of programs that can promote the positive development of social competence among rural children.
