The present research work is on the effect of sawdust ash (SDA) on the mechanical strengths of self compacting concrete (SCC) using naphthalene sulfonate (NS) as a plasticizer. Experiments on compressive, flexural and splitting tensile strengths are conducted and the data analyzed using the Minitab 15 software. The results showed that SDA can defer the reaction of cement hydration and prolong the setting times of cement paste. This was very much pronounced on the flexural and splitting tensile strengths at 90 days of curing which are 36 % and 33 % higher than the control strengths, respectively. The study has proposed strength relations of mortar compressive strength with the flexural and splitting tensile strengths and these are, 5 and 7 times respectively. The flexural strength is 1.5 times that of the splitting tensile. Finally, linear models were developed on these relationships.

The purpose of this study was to analyze the effective variables which influence family strengths. In particular, influencing variables were analyzed according to sex, generation, and family pattern. There were 703 participants aged over 20 years in Gwangju and Seoul. All participants completed a questionnaire and the data were analyzed using SPSS. The results were as follows: 1. The average scores of family strengths were higher than the median. Regarding subdimensions, 'value system sharing' had the lowest score. 2. Family strengths were related to its subdimension and some variables. 3. Family strengths were influenced by living condition, self-esteem, depression, the cognition of family function, and family value orientations. However, the influencing variables were different according to sex, generation, and family patterns. In conclusion, in order to improve family strengths, it is necessary to develop 'value system sharing', enhance self-esteem, and reduce depression. Further, when we deal with family strengths, it is necessary to vary methodology.

This study is for examining the differences of perceived stresses and family strengths between the parents according to socio-demographic backgrounds(age, educational level, income and the degree of disorder) of the parents having mentally retarded children. The results were as follows. First, in the overall perceived stress level, there was no difference between fathers and mothers, but when compared in stress areas, fathers experience more distresses in general interpersonal areas than mothers. Fathers also shows differences according to the degrees of their income and their perception about disorder compared with mothers showing differences according to the degree of income. Second, there were no differences in family strengths perceived by both fathers and mothers, but were significant differences according to the level of education and income. Another words, higher the education and income level, higher is their family strengths level. Third, there were positive correlations between the perceived stresses and family strengths, and significant differences in family strengths according to the stress level(higher/lower part of the group). In other words, when the perceived stress level is high, the level of perceived family strengths is low.

The purpose of this study was to analyze relationships between mother's psychological controls, family strengths, and psychological well-beings as perceived by children. In total, 529 6th graders from Seoul and Buchon participated in the study, Results were as follows: Firstly, gender differences were observed in the awareness of psychological well-beings but not in perception of mother's psychological controls and family strengths. Secondly, the children's awareness of mother's psychological controls and family strengths were correlated with their psychological well-beings the more children were aware of their mother's psychological controls, the less likely they were to be aware of their family strengths and psychological well beings. Finally, children's awareness of family strengths had remarkable influence on their psychological well-being.

This study was conducted to examine how family strengths are affected by parenting stress, socio-demographic factors and communication strategy, with a specific focus on mothers with young children. In total, 418 mothers of 4-5 years old children were included in this study. Higher education achievement was significantly related to higher communication strategy and better family strengths. However educational background had no effect on degree of parenting stress. Lower household income was related to higher parenting stress while higher income resulted in stronger family strengths. However family income showed no correlation with communication strategy. Lower parenting stress and higher communication strategy contributed to better family strengths, The most influential factor of family strengths was parenting stress.

Purpose: The family is a primary environment and has pivotal role for child health and development. This study was conducted to identify the relations of family strengths to body image and self-esteem in late school aged children. Methods: Data were collected from 455 children at 5th and 6th grades in four provinces of South Korea using self-report questionnaires for measuring body image, self-esteem, and family strengths. Pearson's correlation analysis and t-test, ANOVA were used to identify the relationships among variables, and compare body image, self-esteem, and family strengths according to general characteristics. Results: Body image, self-esteem and family strengths were significantly different according to economic status and academic performance. Family strengths were also affected by the presence of both parents. Body image, self-esteem and family strengths showed significant positive correlations. Conclusion: The family relations of school aged children are important for child's body image and self-esteem. We recommend that psycho-emotional interventions should be developed for both the children and their parents with low family strengths to improve body image and self-esteem.

Objective: The purpose of this study was to examine cluster types according to the playfulness factors of young children and to predict the character strengths of young children which have an influence on the types of children's playfulness. Methods: Playfulness and character strength tests were administered to 237 young children. The playfulness groups were classified by cluster analysis and the logistic regression analysis. It was used to find the character strengths of young children that have a effect on the types of children's playfulness. Results: First, the children's playfulness groups were divided into a high playfulness group and a low playfulness group. Second, there was a significant difference in all character strengths according to the children's playfulness cluster, and the high playfulness group was statistically significantly high in all character strengths. Third, the children's character strengths influencing the high playfulness group were vitality and positivity, self-regulation, self-esteem, and sensibility. Conclusion/Implications: Based on these results, the necessity of supporting these character strengths was discussed in order to improve the playfulness of children in the education field.

The purpose of this study was to investigate the strengths of single-parent families and the related variables based on the family strength approach. The major findings were as follows. First, good communication, family bond, children's adjustment and coping ability were characteristics of single-parent family strengths. Secondly, strengths of single-parent family were related to income and period of becoming a single-parent family. Thirdly, single parents who had a higher level of personal resources such as high self-esteem and economic stability perceived a higher level of family strengths. Fourth, single parents who had a higher level of social support perceived a higher level of family strength. Fifth, there was no interaction effect between personal resource and social resource on single-parent family strengths. Last, both personal and social resources had effects on the strength of single- parent family. Especially personal resource and self-esteem were the most important variables and had a strong influence on single-parent family strengths. The results of this study have important implications for theory, research and practice. Research on the strengths of the Korean single-parent family is new and more extensive investigation is required.
