In recent years, geopolymer cements, have gained significant attention as an environmental-friendly type of cement. In this experimental research, effects of different alkaline activator solutions and variations of associated parameters, including time of addition, concentration, and weight ratio, on the mechanical strengths of Granulated Ground Blast Furnace Slag (GGBFS)-based Geopolymer Concrete (GPC) were investigated. Investigation of the effects of simultaneous usage of KOH and NaOH solutions on the tensile and flexural strengths of GGBFS-based GPC, and the influence of NaOH solution addition time delay on the mechanical strengths is among the novel aspects investigated in this research. four series of mix designs and corresponding specimen testing is conducted to study different parameters of the active alkali solutions on GPC mechanical strengths. The results showed that addition of NaOH to the mix after 3 min of mixing KOH and Na2SiO3 with dry components (1/3 of the total mixing duration) resulted in the highest compressive, tensile and flexural strengths amongst other cases. Moreover, increasing the KOH concentration up to 12 M resulted in the highest compressive strength, while weight ratio of 1.5 for Na2SiO3/KOH was the optimum value to achieve highest compressive strengths.

This study examined the mediating effects of strengths use on the relation of strengths knowledge and career decision level among 393 college students. To analyze the data, the structural equation modeling were used. Finally, the mediating model examined the differences between goal orientation(validation-seeking orientation, growth-seeking orientation) of Dykman by carrying out of multi-group analysis. The results were as followed. First, strengths use partially mediated the relationship between strengths knowledge and career decision level. Second, the mediating model showed variation in different goal orientation type group. In other words, strengths knowledge occurs more severely and distinctively impact on career decision level in growth-seeking group than validation-seeking group. Based on the findings, implications for counseling practice, limitations of this study and recommendations for future study were discussed.

Purpose: This study was undertaken to identify the mediating effect of family strengths in the relationship between e-learning readiness and learning management system-based online education learning outcomes. Our results provide basic data for proposing strategies to increase online education learning outcomes of nursing students. Methods: A self-report questionnaire was surveyed by 133 nursing students who took online education using a learning management system at three nursing colleges in Daejeon, Jeonbuk, and Gyeongbuk. The mediating effect of family strengths in the relationship between the e-learning readiness of the subject and online education learning outcomes, were analyzed by hierarchical multiple regression. Sobel test was performed to verify effectiveness of the pathway. Results: In the relationship between e-learning readiness and online education learning outcomes of nursing students, family strengths were determined to exert absolute mediating effect. Conclusions: Our results indicate that in order to improve e-learning readiness, the basic curriculum for nursing students should include web-based communication, cooperation, and the use of information technology, including interaction for online education. Improvements in family strengths can be achieved through home study activities, such as frequent conversations with members, monitoring achievements of the students, and sharing family leisure activities.

This study attempted to: (1) operate a Strengths-based case management program; (2) determine the effectiveness of strengths-based case management for the elderly; (3) evaluate the effect of the coordinating program on the capabilities of ADL, IADL, and life-satisfaction of the elderly. The subject of this study was 8 home-bound elderly in lowest income class in Gwang-ju City. The program was practiced from November 2008 to April 2009 for 6 months period. The outcome of study has shown that strengths-based case management has determined a fair of amount of effectiveness in carrying out their short-term tasks. The program tried to assess the strengths of the elderly, and evaluate the outcomes of the program using ADL, IADl items and life-satisfaction developed for the study. The data collected by pre-test and post-test of the program showed that the scores of life-satisfaction were improved statistically significantly. But capabilities of ADL, IADL items were slightly improved, but not statistically significant. Successive effort to operate strengths-based case management must be required for the improvement of capabilities of ADL, IADL, and quality of life of the elderly.

The primary objective of the research is to develop a mathematical method to incorporate the variability of anthropometric body dimensions and joint strengths of individuals in a biomechanical analysis. A multivariate normal simulation model estimated anthropometric body dimensions and joint strengths of the random link-person, based on the assumptions that the vari- ables of body dimensions and joint strengths are correlated and follow normal distributions. Statistical comparative analysis demonstrated that the random link-person represented a more realistic human-like form in an anthropometric sense than the proportional link-person whose body dimensions were estimated proportionally. Estimated joint strengths for the random link-person, however, did not match the measured joint strengths as closely as the estimated body dimensions. The random link-person will allow biomechanical analysis of manual materials handling tasks to be individualized with respect to the anthropometry and a static strength.

This study analyzed the pattern of preschool children's abilities based on Project Spectrum and compared the relationship between intelligence domains with working styles of children. Generally, children showed both strengths and weaknesses in specific Spectrum domains, but some children had only strengths and others had only weaknesses without strengths. It appeared that working style does not relate to children's strong domains, but individual disposition was reflected by characteristics of the task. During both individual and group spectrum activities, children with strengths were more "easily engaged in activity", "confident", and "focused" than those without strong intelligence domains. During individual activities, the "reflective" domain showed children with strengths in intelligence domains are more reflective than those without strengths.

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.

The purpose of this study was to develop and validate the Korea Family Strengths Scale II (KFSS-II) which was modified and developed by Yoo(2004). For this purpose, the preliminary scale of family strengths which was based on Yoo(2004)'s sample survey that targeted 494 adults who live in Korea consisted of 30 items. Exploratory factor analysis of 29 items extracted 5 factors. It included the 5 dimensional constructs of family resilience, valuing each other & acceptance, qualitative bonding, economic stability and cooperation and caring about community. Confirmatory factor analysis confirmed the stepwise 5-factor model of 22 items considering family strengths. These results indicated that the simple template of Family Strengths Scale would be a concise and reliable tool for assessing and evaluating a family's strengths.

This study aimed to investigate the effects a strengths-based group counselling program had on self-esteem and career maturity of adolescents under probation. The subjects of the study were female adolescents under probation in Gwangju and were categorized into two groups: experiment group and control group consisting of 15 respectively. As a result, it was discovered that the strengths-based group counselling program had positive effects on enhancement of general and social self-esteem in the subjects while it did not have statistically significant effects on enhancement of family self-esteem. It indicates that positive relationship with parents and recovery of family functions should be encouraged to enhance the family self-esteem. Also, the strengths-based group counselling program had positive effects on planning, self-understanding, career knowledge and career preparation areas relating to career maturity while it did not have statistically significant effects on independence. It shows that to encourage the subjects to be independently prepared for career, family and society should provide more specific support for career guidance. Based on the results above, it was suggested that the strengths-based group counselling program had significant effects on self-esteem and career maturity of the subjects under probation. In conclusion, to encourage adolescents under probation to respect themselves and others, specifically plan their career and grow to be reliable and mature adults, further research on the strengths-based group counselling program is needed and diverse strategies including specific support through mentor service of college students should be developed.
