This study examined the influence of mothers' reading and scaffolding behaviors on children's emotional experiences and memory recall during picture book reading. Sixty children, aged 6 and their mothers participated in this study. Each child-mother dyad was observed in a lab setting which was designed to evaluate child-mother interactions during a picture book reading. The data were analyzed using correlation and multiple regression techniques. Our results indicated that mothers' task-oriented reading behavior affected the children's lack of positive emotions, whereas mothers' fun-oriented reading behavior was associated with the children's positive emotions. The task-oriented reading behavior also accounted for children's poor memory performance in relation to the book. These results were discussed in terms of the relationship between emotion and cognition through book reading experiences.

The aim of this study was to investigate the factors affecting earth science problem-solving performances of elementary school pre-service teachers. The participants of the study were 81 students attending an elementary school teacher education university. The instruments of the study were paper-and-pencil tests, questionnaires, and interviews. The tests mainly measured the participants' problem solving abilities in the motions of the moon and the planets. Correlation and multiple regression techniques were used for data analysis. The results demonstrated that the pre-service teachers' problem solving abilities were low. Problem-solving performances were affected by the procedural knowledge, the participants' perception of the past earth science performance, self-efficacy, and the prerequisite declarative knowledge. Contrary to our expectation, the spatial visualization ability was not found to be related to the problem-solving performances. Implications of the study are drawn, and suggestions are made for further research.

The purpose of this study is to analyze the relationship between decision making abilities young children and their self-directed learning abilities. A survey was carried out using 160 young children in the J region. The collected data were analyzed by Pearson correlation and multiple regression techniques using the SPSS statistics program. The conclusions are as follows : First, decision making abilities in young children exhibited a positive correlation with their self-directed learning abilities. Second, decision making abilities in young children were an influential variable in terms of their self-directed learning abilities. As a result, decision making abilities in young children were an important variable in predicting their self-directed learning abilities.

A linear quantitative structure-property relationship (QSPR) model is presented for the prediction of rejection in permeation through membrane. The model was produced by using the multiple linear regression (MLR) technique on the database consisting of retention data of 25 pesticides in 4 different membrane separation experiments. Among the 3224 different physicochemical, topological and structural descriptors that were considered as inputs to the model only 50 were selected using several criteria of elimination. The physical meaning of chosen descriptor is discussed in detail. The accuracy of the proposed MLR models is illustrated using the following evaluation techniques: leave-one-out cross validation procedure, leave-many-out cross validation procedure and Y-randomization.

Employees of sales departments of apparel makers play an important role in the success of a fashion-related business because they provide service through the direct contact with customers. This research tests several hypothesized relationships between its determinants, such as job satisfaction and customer orientation, along with service delivery level. The subjects in this study were salespeople who worked at fashion stores in Yeosu and Sunchon. To measure the hypotheses, 200 questionnaires were handed out and 185 were collected. 163 questionnaires were used for the analysis, as 22 were found to be invalid. Frequency analysis, factor analysis, reliability analysis, and multiple regression techniques were used after coding and cleaning the data with the software SPSS 18.0. The result of this study are as follow. First, job satisfaction have a positive influence on employee's customer orientation. Second, job satisfaction have an effect on procedural and hospitable service delivery level. Third, it was found that the customer orientation have a significant impact on their procedural and hospitable service delivery level.

Foundry techniquews for large steel casting depends on the skills of foundrymen considerably. Especially, the problem of reducing casring surface defects is difficult to clear numerically. Statistical analysis by using wuantification theory for hot tear and sand inclusion, and multiple regression analysis for dimensional defects have been shown to be examples of solving this difficulty. Many causes of surface defects can be evaluated by these analyses. These evaluations serve as the base data of defect reduction and contribute to the constant improvement of casting quality and quality enhancement activity. The system to perform quality enhancement activity was developed and it proved very useful for transfering foundry techniques and skills from the old to young generations.

Bankruptcy prediction has drawn a lot of research interests in previous literature, and recent studies have shown that machine learning techniques achieved better performance than traditional statistical ones. This paper employs a relatively new machine learning technique, support vector machines (SVMs). to bankruptcy prediction problem in an attempt to suggest a new model with better explanatory power and stability. To serve this purpose, we use grid search technique using 5-fold cross-validation to find out the optimal values of the parameters of kernel function of SVM. In addition, to evaluate the prediction accuracy of SVM. we compare its performance with multiple discriminant analysis (MDA), logistic regression analysis (Logit), and three-layer fully connected back-propagation neural networks (BPNs). The experiment results show that SVM outperforms the other methods.

The purpose of this study is two fold: 1) To find out if perceived parental child-rearing attitudes have any relationship with sex of children and education of the parents. 2) To investigate how and what extent perceived parental child-rearing attitudes affect the sex-role traits of children. In order to pursue the above purposes, the Bem Sex Role Inventory (BSRI) and perceived parental child-rearing attitudes questionnaire were administerd to 127 6th elementary school children in Gwang Ju. For data analysis, such techniques as multiple regression and pearson correlation were applied. The results of this study are summarized as follows: 1) Both boys and girls perceived more positive attitudes by mothers than by fathers 2) Some effects of sex differences and education of parents were found in the perceived parental child-rearing attitudes and sex-role traits of children. 3) Perceived parental attitudes had significant effects on children's sex-role traits.

As a methodology for this study, questionnaire survey were used. The number of 228 cases were analyzed through SPSS PC+. For the analysis of the data, such techniques were used as reliability analysis, frequence analysis, factor analysis, correlation analysis, and multiple regression analysis.The major findings of this study were as followings: 1. Housing life styles of apartment dwellers by alteration in Ulsan identified five factors.

Subjects were 279 parents of 4- and 5-year-old day care children. Statistical techniques were factor analysis, t-test, ANOVA, Pearson's correlation, and multiple regression. Major findings were that parents with higher levels of education and income showed a higher level of attitudes and coping behavior toward preschoolers' exposure to secondhand smoke. Parents who were smokers had a higher level than non-smokers of knowledge and coping with preschoolers' secondhand smoke. Parents with higher levels of knowledge and more negative attitudes about secondhand smoke were more active in dealing with secondhand smoke. Parents' knowledge and attitudes were significant predictors of their coping behavior with preschoolers' secondhand smoke. Parents' knowledge was more predictive of parents' coping behavior than their attitudes.
