This study examined the effect of preschooler's emotional intelligence, child-teacher relationships (intimacy, conflict and dependency) on children's social competence. A sample of 269 children (142 boys and 127 girls) aged 3 to 6 in Seoul or Gyeonggi-do participated in the Emotional Intelligence Scale, the Child-Teacher Relationships Scale and Social Competence Scale by teachers. Descriptive statistics, t -test, Pearson's correlation analysis and regression analysis analyzed data via SPSS ver. 20.0. This study followed a mediated effect model. The results showed that: (1) The emotional intelligence of girls was significantly higher than boys. However, the child-teacher relationship and children's social competence had no significant difference relationship to gender. (2) There was a mediating effect of child-teacher relationships between preschooler's emotional intelligence and social competence. The effect of emotional intelligence on social competence was partially mediated by intimate relationship, conflict relationship and dependency relationship. The degree of mediating effect was investigated in regards to conflict relationship, dependency relationship and intimate relationship. This study demonstrated that child-teacher relationships mediate the relationship between emotional intelligence and social competence of preschoolers.

This study proposes a multi-level data analysis approach to identify both superficial and latent relationships among variables in the data set obtained from a vocational rehabilitation (VR) services program of people with significant disabilities. At the first layer, data mining and statistical predictive models are used to extract the superficial relationships between dependent and independent variables. To supplement the findings and relationships from the analysis at the first layer, association rule mining algorithms at the second layer are employed to extract additional sets of interesting associative relationships among variables. Finally, nonlinear nonparametric canonical correlation analysis (NLCCA) along with clustering algorithm is employed to identify latent nonlinear relationships. Experimental outputs validate the usefulness of the proposed approach. In particular, the identified latent relationship indicates that disability types (i.e., physical and mental) and severity (i.e., severe, most severe, not severe) have a significant impact on the levels of self-esteem and self-confidence of people with disabilities. The identified superficial and latent relationships can be used to train education program designers and policy developers to maximize the outcomes of VR training programs.

For the purpose of encouraging healthy eating habits, this study surveyed 282 male and female university students in Busan to investigate the relationships between dining-out activities, eating habits, and the frequency of fast food intake and obesity. To confirm this, SPSS statistical programme 14.0 has been used to carry out the frequency analysis, fact and reliability analysis, $x^2$-test, t-test and the correlation analysis. As a result, it has been found that there is a correlation under p<0.01 between obesity and the habit of frequently eating unhealthy food, and there is a correlation under p<0.01 between obesity and the habit of frequently fast foods. Meanwhile, there is a correlation under p<0.05 between obesity and regular eating habits. Therefore, it has been concluded that there is a correlation between the obesity and eating habits as well as the frequency of fast food intake among the university students.

Line graphs are frequently used to communicate data and basic concepts in classroom activities, Science teachers often assume that students are able to interpret the symbolic meaning of the graphs, but such an assumption is not based on sufficient evidence, The purpose of this study was to investigate the relationships of graphing ability to science-process skills and academic achievement of high school students: With regard to science-process skills, graphing ability was found to have a slight correlation with science-process skills (.41). Among the sub-skills of the science-process, graphing ability was seen to have a relatively high correlation with basic science-process skills such as 'measuring', 'inferring', 'predicting', while having relatively low correlation with integrated science-process skills such as 'formulating hypothesis' and 'generalization', With regard to academic achievement, graphing ability appeared to have no correlation with academic achievement (.06). Hence, a correlation between graphing ability and science-process skills was proved. It can also be concluded that improving graphing ability will greatly support students with their science study and, therefore, organized efforts and efficient educational methods should be developed in order to overcome the insufficient graphing ability among high school students.

This article is concerned with the importance of organisation management and its characteristics in business performance in SMEs, and tested by four main aspects: managerial strategies, organisational structure, leader behaviour, and R&D activities. These relationships were tested with questionnaire data from a random sample of 87 firms. Results from simple statistics on each issue showed that SMEs have focused on the corporate growth and management goals, the democratic leadership, decentralisation in organisational structure, and the technology development plans. Results from correlation analyses not only found significant relationships between managerial strategy and R&D activities but also showed differences in R&D activities according to structural status or leadership style, respectively.

We have re-examined the linear solvation energy relationships in reversed phase liquid chromatography by considering various solutes including quite a number of compounds of strong hydrogen bond capability. We observed that solutes of strong hydrogen bond ability should be excluded in order to obtain resonable correlations between In k' and solute polarity parameters and that inclusion of one or two such solutes causes severe distortions of correlation results. This anomaly may be due to existence of residual silanol groups in the stationary phase, that is, their specific interactions with solutes.

In this paper, we address the derivation of joint distributions and correlation coefficients for three pairs of statistics used commonly in a number of signal detection schemes. The upper and lower bounds of the correlation coefficients for the three pairs are obtained, and interesting relationships between the correlation coefficients are derived. Explicit values of the correlation coefficients evaluated for some meaningful distributions are given in the form of tables and figures for easy reference. The results in this paper should be useful in comparing various detection statistics.

This research was conducted to explore relationships among situation awareness, presence, and performance on a handheld game console. Situation Awareness was measured by SAGAT (Situation Awareness Global Assessment Technique) while presence was measured by PQ (Presence Questionnaire) version 3.0. The performance was measured by the number of aircraft shot down during the flight simulator game. The results show that both situation awareness and presence were positively significantly correlated with performance. In order to investigate the effect of performance level, subjects were divided into two significantly different groups: low and high performance groups. In the low performance group, both situation awareness and presence showed a significantly positive correlation with performance. The correlation between presence and situation awareness also showed a positively significant correlation. However, in the high performance group, there were no significant correlations among them. In conclusion, different performance levels could be said to be an important factor in the study of situation awareness and presence. Furthermore, this study also proved that the domain of research on situation awareness and presence was extended to small displays such as the handheld game console.

This study examined the relationships between clothing values, wearing behaviors and the attitudes toward underwear for female students. A survey of female middle and high school students was conducted. 584 questionnaires, collected from April to May, 2009, were analyzed using descriptive statistics, cross tabulation analysis, t-test, factor analysis, and Pearson's correlation coefficient. Economic and aesthetic value were found to be significantly higher than other clothing values amongst older students while students in coeducational schools regarded aesthetic properties of clothing as being more important (p<.05). Girl students' most pursued attitudes toward underwear was modesty. According to age of students and the type of school they attended there were significant differences in students' underwear wearing behaviors. A high level of correlation between clothing values and attitudes toward underwear was found. Aesthetic value out of the clothing values showed a high correlation with esthetics/sexual attractiveness out of the attitudes toward underwear. Aesthetics/sexual attractiveness out of the attitudes toward underwear was shown to be most influential on underwear wearing behaviors. There would be a necessity for emphasizing the wearing of girdle and slip.

Objective: The purpose of this study was to examine the relationships among teachers' resilience, difficulty in emotional regulation, and teaching strategies for behavior problems of children. Methods: A total of 200 day care and kindergarten teachers were surveyed. The collected data were analyzed by Pearson's correlation and multiple regression. Results: First, teachers' resilience, difficulty in emotional regulation and teaching strategies for children with behavior problems were significantly related. Teachers' resilience showed a positive correlation with teachers' positive prevention and reaction strategies but showed a negative correlation with teachers' negative reaction strategies. Among the teachers' difficulty in emotional regulation, the factor of difficulty for impulsive control and lack of attention showed negative correlations with teachers' prevention and positive reaction strategies. Second, teachers' resilience and difficulty in emotional regulation significantly explained the teaching strategies for children with behavior problems. Teachers' resilience was found to be the most important variable explaining teaching strategies for children with behavior problems. Conclusion/Implications: This study revealed that teachers' resilience and difficulties in emotional regulation were important psychological and emotional characteristics for teachers when teaching children with behavior problems.
