The purpose of this study is to confirm whether the parenting stress of mothers with preschool children mediated the parent-child interaction and parenting attitude on children's learning readiness. Data was used from the 5th (2012) to 7th (2014) Korean Children's Panel, and a total of 1,480 data sets were used for the analysis. The age of study participants was five years old. The Amos 23.0 program was used as an analytical tool, and the structural equation model analysis was applied to estimate the path coefficient corresponding to the research question. First, it was expected that mothers' parenting stress negatively affected the parent-child interaction, mother's parenting attitude, and children's readiness. Second, it was assumed that parent-child interaction and the mother's warm parenting attitude were positively significant to children's readiness. Third, the relationship between the parenting stress of mothers and children's learning readiness was partially mediated by a positive parenting attitude. The current study supplies valuable data to establish the educational support and efficiency strategy for domestic children. This study is meaningful in that it provides basic data in preparing a plan to more effectively provide educational support for domestic children.

SNS has been emerged as an effective educational tool in college and many studies on various teaching models and methodologies have been made in order to utilize SNS in education. The purpose of this paper is to empirically investigate the effect of affecting factors of SNS on learner's attitude, intention to re-use and performance in converging college educational environment. Self-efficacy on media usage, educational expectancy, subjective norm, habit, and enjoyment were identified as affecting factors based on prior researches. An empirical analysis was attempted by survey targeting college students. The results of structural equation model using Smart PLS shows that educational expectancy, subjective norm, and enjoyment are significantly related to the learner's attitude on use of SNS in college education, but Self-efficacy on media usage and habit are not. Learner's attitude on SNS in college education was found to be significantly related to the intention to continuous use and performance. This study implicates that using SNS in university class makes learner's attitude positively and finally lead to good performance. The analysis results can provide a guideline of effective strategy for SNS utilization in college education.

In this paper, experimental program and associated numerical study were carried out to evaluate the fire resistance of unprotected concrete-filled rectangular steel tubular (CFT) columns subjected to the standard fire. The key testing parameters included the length effect, the load ratio, and the sectional dimensions of the CFT columns. Temperature distribution and axial deformation of the CFT column specimens were measured and analyzed. Rather early local buckling of steel tubes was observed in all the specimens. This caused subsequent load transfer from steel tube to concrete, and eventually triggered concrete crushing, or complete loss of the load bearing capacity of the column. This implies that the limit state of local buckling as well as overall flexural buckling should be incorporated in fire design procedure. As expected, the fire resistance time of specimen with higher load ratio consistently lessened. The prediction of fire resistance time of unprotected CFT columns based on the limiting steel temperature in current design codes or the formula proposed by previous studies is slightly conservative compared to the fire test results available. To establish the finite element analysis model that can be used to predict the thermal and structural behaviour of unprotected CFT columns in fire, the fully coupled thermal-stress analysis was also tried by using the commercial code ABAQUS. The numerical results showed a reasonable global correlation with the experimental results.

This study compares and analyzes the characteristics and effects of various educational contextual variables according to students' achievement level and gender groups based on the results of PISA 2015 science domain. PISA 2015 included additional variables about teaching-learning and affective characteristics in the field of science, because science was the main domain of PISA 2015. The results of the mediation analysis using a multiple group structural equation model showed that the environment and strategy for the teaching and learning had a positive effect on the affective characteristics, and also positively affected science achievement through the mediator of the affective characteristics. Particularly, the environment and strategy for the teaching and learning was the most effective in improving the affective characteristics for the low achievement group. It was found that the difference of the mediated effect between achievement level groups was statistically significant, but that between male and female students was not. Therefore, the appropriate the environment and strategy for the teaching and learning will need to be emphasized consistently to improve students' cognitive and affective achievement. The implications and suggestions of these results were discussed.

The public perceptions about the cause of the poverty are generally considered as the important subject because they are assumed to have profound influences on the anti-poverty strategies, the features of the welfare system, and the welfare politics. Yet, there have been few studies on the public perceptions about attributions for poverty in Korea. In this article, we explore the popular perceptions about the causes of the poverty and investigate the determinants of the various beliefs about the causes of the poverty in Korea. The data derive from the Welfare Attitudes data of the 8th Korea Welfare Panel Survey. The results indicates that Koreans are more likely to support the individualistic explanations on the causes of the poverty than the structural and the fatalistic explanations. The results of regression model analysis show that there are differences in the determinants of the three types of poverty explanations, but subjective variables have the strong effects on all of the poverty explanations in Korea. In this study we find that Koreans are more likely than the western european welfare states to endorse individualistic explanations. These findings suggest that the underdevelopment of the welfare system in Korea is assumed to have the connection with the popular individualistic explanations. And, they suggest that there are needed to have notices to changing the public perceptions of the poverty and the cultural context of the social welfare in order to advance the welfare state in Korea.

This study examines the degrees of criminal investigators' job satisfaction and organizational commitment and investigates which factors determine the variations in them. In the first step of analysis, independent variables of criminal investigators' job satisfaction consist of work itself, achievement, responsibility, safety, stability, interpersonal relations, recognition, supervision, and opportunity of growth. In the second step, job satisfaction is a mediating variable and organizational commitment is a defendant variable. Organizational commitment is classified into three types - "affective", "continuance" and "normative". According to the structural equation model analysis, responsibility has a great influence on job satisfaction, and job satisfaction affects affective commitment and continuance commitment. This study suggests that job satisfaction should be increased to improve criminal investigators' organizational commitment. And responsibility is necessary for the improvement of job satisfaction. Despite the professional detective system operating in Korea since January 1, 2005, the level of criminal investigators' recognitions of safety, stability and opportunity of growth turn out to be low. Based on these findings, this study presents four ways to reform measures which are listed below. First, to improve a! n economical circumstance of criminal investigators, any expense associated with criminal investigation should be paid by organizations. Second, to improve safety of criminal investigators, it is necessary to develop and supply enough police equipments. Third, criminal investigators' working hours should be shorten. Fourth, to improve criminal investigators' responsibilities, criminal investigators should be allowed to conduct criminal investigation independently from the prosecution.

The purpose of this study was to examine the mediating effects of mattering and unconditional self-acceptance in the relationship between college student socially-prescribed perfectionism and social anxiety. For this purpose, a questionnaire was conducted for students in college and a total of 408 copies were used for analysis. The instruments used in the measurement were socially prescribed perfectionism scale(HFMPS), social anxiety scale, mattering scale, and unconditional self-acceptance. The collected data were analyzed by descriptive statistics and correlation analysis using SPSS 21.0, and the structural equation model and mediating effects were verified using Mplus 7.0. The results of the study are as follows. First socially-prescribed perfectionism showed a positive correlation with social anxiety but negative correlation with mattering and unconditional self-acceptance. And there was a positive correlation between mattering and unconditional self-acceptance but negative correlation with social anxiety. Second, the mediating effect of mattering was confirmed in the relationship between socially-prescribed perfectionism and social anxiety. Third, the mediating effect of unconditional self-acceptance was confirmed in the relationship between socially-prescribed perfectionism and social anxiety. Fourth, the effect of double mediation of mattering and unconditional self-acceptance was confirmed in relation to socially-prescribed perfectionism and social anxiety in college students. Based on these findings, the implications of the study were presented and the limitations of the study and suggestions for further research were discussed.

Purpose - Previous studies have not paid attention to global self-corporate brand congruity and affective approach from the viewpoint of global self. This study explored an inducement of gratitude that, under the circumstance of corporate association, consumers feel toward corporate's responsible activities, pride related to corporate's ability, and global self congruity. Current researches also have examined positive behavior effects of global self-corporate brand congruity and the feelings on corporate products. Research design, data, and methodology - This research theoretically reviewed that corporate ability and social responsibility association would influence global self-corporate brand congruity, that corporate ability association could induce consumers' sense of pride, and that social responsibility association might induce gratitude. This study, furthermore, examined theoretically whether global self-corporate brand congruity, pride and gratitude could make consumers behave positively toward corporate products, and developed hypotheses. For the empirical analysis with the questionnaires, 231 employees and common people completed the questionnaires, and structural equation model of AMOS 18.0 was used. Results - From the empirical analysis, the outcomes are as followings. First, corporate ability association makes consumers feel proud. Second, corporate social responsible association makes consumers feel grateful. Third, both corporate ability association and social responsibility association let consumers be aware of global self-corporate brand congruity. Fourth, being conscious of each of pride, gratitude and global self-corporate brand congruity prompts consumers to behave positively toward corporate products. Fifth, mediation effects of pride and the congruity in the roles of corporate ability association on the positive behavior, and those of gratitude and the congruity in the roles of corporate social responsible association on the positive behavior are identified. Conclusions - Based on the results, it can be said that a marketing manager should endeavor to make consumers associate the corporate ability and social responsibility. However, the degree of consumers' feelings such as pride and gratitude can differ according to their cultural backgrounds. It is, therefore, needed to be explored by the types of feelings that can be caused more from the difference in cultural backgrounds by corporate association, and to be investigated differently and positively with behavioral effects on the corporate's products between the types.

This paper attempted to find the convergence factors related to the organizational citizenship behavior of hospital administration staff(HAS). The survey was conducted on 274 administrative staff at 22 hospitals in J regions randomly selected using self-administered questionnaires. The survey period took about a month from July 1 to July 31, 2019. The hierarchical multiple regression analysis shows the following results. The organizational citizenship behavior of respondents turned out to be significantly higher in following groups: The higher the procedure justice, sub-areas of organization justice, the higher the intragroup trust, and the higher the organizational commitment. Their explanatory power was 41.9%. The results of the study indicate that the efforts, to increase organization justice, intragroup trust and organizational commitment, are required to improve organizational citizenship behavior among HAS. The above results are expected to be utilized in human resource management and industrial health education of medical institutions that enhance organizational citizenship behavior of HAS. Later research requires the establishment of a structural equation model that affects organizational citizenship behavior of HAS.
