This study aims to examine the effects of high school students' time management behaviors on their satisfaction with educational consumption and school life. Three hundred seventy-six high school students in Seoul participated in this investigation. The SPSS ver. 19.0 program was adopted for the descriptive analysis, factor analysis, Cronbach's ${\alpha}$, and multiple regression analysis. The results of the present study can be summarized as follows: first, the levels of time management behavior, satisfaction with educational consumption at school, and satisfaction with school life were relatively high. Second, an analysis of the relative influence on satisfaction with educational consumption revealed that the students' time management behavior was the most influential factor, followed by academic achievement. As the levels of time management behavior and academic achievement were high, the level of satisfaction with educational consumption was high. Finally, an analysis of the relative influence of satisfaction with school life also revealed that the students' time management behavior was the most influential factor, followed by academic achievement. Based on the findings, that is, the effects of high school students' time management behavior and other involved variables on their satisfaction with educational consumption and school life, a future study can present specific ways to enhance the level of satisfaction with educational consumption and school life.

The purpose of this study was to examine the effects of parenting efficacy, parenting behavior, and parenting stress on children's problematic behavior in Korea and China. The subjects were 292 children and their mothers who are caring for their 3-5 years old children in Korea and China. Data was collected using a parenting efficacy index, parenting behavior index, parenting stress index and child behavior check list. The data were statistically analyzed using t-test, one-way ANOVA (Scheff$\acute{e}$ test), correlation analysis and multiple regression analysis. The study showed that there were no significant differences in parenting efficacy, parenting behavior, parenting stress and children's problematic behavior in Korea and China. There were some significant differences in children's problematic behavior according to the socio-demographic variables, that is the gender of the child, the mother's education, the father's education, in Korea and China. Correlation analysis indicated that the parenting efficacy, parenting behavior, parenting stress and children's problematic behavior in Korea and China had significant correlations in some sub-variables. It was also found that the gender of the child, the mother's education, the father's education, the frustration and uneasiness of the parents, the control behavior, and the stress of parent-child dysfunctional interaction, were all significant predictors of the preschool children's problematic behavior in Korea, and the mother's education, the family income, the affection behavior, the rejection behavior, and the control behavior, were all significant predictors of the preschool children's problematic behavior in China.

Theoretical mechanics analysis and finite element simulation were performed to investigate creep deformation behavior at the crack tip of transversely isotropic materials under small scale creep (SCC) conditions. Mechanical behavior of material was assumed as an elastic-$2^{nd}$ creep, which elastic modulus ( E ), Poisson's ratio ( ${\nu}$ ) and creep stress exponent ( n ) were isotropic and creep coefficient was only transversely isotropic. Based on the mechanics analysis for material behavior, a constitutive equation for transversely isotropic creep behavior was formulated and an equivalent creep coefficient was proposed under plain strain conditions. Creep deformation behavior at the crack tip was investigated through the finite element analysis. The results of the finite element analysis showed that creep deformation in transversely isotropic materials is dominant at the rear of the crack-tip. This result was more obvious when a load was applied to principal axis of anisotropy. Based on the results of the mechanics analysis and the finite element simulation, a corrected estimation scheme of the creep zone size was proposed in order to evaluate the creep deformation behavior at the crack tip of transversely isotropic creeping materials.

The purpose of this study was to examine the relation of elementary school children's stress and coping behavior in urban and rural areas. The subject included 286 children selected from 4 elementary schools in urban and rural areas. The instruments included the children's stress index and coping behavior questionnaire of the elementary school children. The statistics used from this data were t-test, one-way ANOVA(Duncan test), correlation analysis and multiple regression analysis. This study showed significant differences between urban and rural children's stress in school attainment domain, teacher-school domain, home environment domain and surroundings domain. And urban and rural children was different in active, passive/avoidant and aggressive coping behavior. The stress of urban's children was influenced significantly by the grade and school attainment variales, and the rural children's stress was influenced significantly by the gender variable. The coping behavior of urban's children was influenced by the gender, grade and school attainment variables, and also the rural children's coping behavior was influenced by the above variables. Correlation analysis indicated that children's stress and aggressive coping behavior were relative positive high correlation in urban areas, and children's stress and passive/avoidant coping behavior were positive high correlation in rural areas. It was also found that school attainment, aggressive coping behavior and passive/avoidant coping behavior were significant predictors of urban children's stress, and gender, passive/avoidant coping behavior and aggressive coping behavior were significant predictors of rural children's stress.

Since human decision making behavior is likely to follow nonlinear strategy, it is conjectured that the human decision making behavior can be modeled better by nonlinear models than by linear models. All that linear models can do is to approximate rather than model the decision behavior. This study attempts to test this conjecture by analyzing human decision making behavior and combining the results of the analysis with predictive performance of both linear models and nonlinear models. In this way, this study can examine the relationship between the predictive performance of models and the existence of valid nonlinear strategy in decision making behavior. This study finds that the existence of nonlinear strategy in decision making behavior is highly correlated with the validity of the decision (or the human experts). The second finding concerns the significant correlations between the model performance and the existence of valid nonlinear strategy which is detected by Lens Model. The third finding is that as stronger the valid nonlinear strategy becomes, the better nonlinear models predict significantly than linear models. The results of this study bring an important concept, validity of nonlinear strategy, to modeling human experts. The inclusion of the concept indicates that the prior analysis of human judgement may lead to the selection of proper modeling algorithm. In addition, lens Model Analysis is proved to be useful in examining the valid nonlinearity in human decision behavior.

Purpose: This study aimed to identify the social responsibility, self-leadership, and career-preparation behavior of fourth-year students graduating from the 4-year program of the department of dental technology and provide basic data for developing specific methods and related programs to help graduates adopt positive and active career preparation behavior. Methods: The final analysis was performed using 143 questionnaires from fourth-year students of the 4-year department of dental technology at Gyeonggi-do, Gangwon-do, and Busan Metropolitan City. T-tests, analysis of variance, correlation analysis, and linear regression analysis were performed in IBM SPSS Statistics ver. 21.0 (IBM). Results: A significant positive correlation was found (p<0.01) between social responsibility, self-leadership, and career preparation behavior factors, and the detailed factors of self-leadership that influence career preparation behavior, "attitude" (p<0.05), "natural reward strategies" (p<0.001), "behavior-focused strategies" (p<0.01), and "constructive thought pattern strategies" (p<0.01) demonstrated significant relationships. The explanatory power values of the models were 50.7% and 52.9%, respectively. Conclusion: This study concluded that to improve career preparation behaviour, social participation through various major volunteer activities is needed to ensure students feel professional responsibility and guide and encourage participation in various self-development programs during their time in university. In addition, universities and departments need to develop step-by-step and various career-preparation behavior programs for each year level.
