The purpose of this study is to determine the relationship among the hypermedia structure(hierarchical and network), learner's cognitive style(field-independent and field-dependent), and learning performance in the elementary school. 128 students(4th graders) having field-independent and field-dependent cognitive style were randomly allocated into hierarchical and network structures of hypermedia learning program. There was not significant interaction between hypermedia structure and cognitive style in learning performance. The students in the hierarchical hypermedia structure showed higher learning performance than ones in the network hypermedia structure. Field-independent students significantly got higher results than field-dependent ones. It is concluded that instructional designers should consider hypermedia structure, learner's cognitive style, and learning outcomes when they plan and design hypermedia learning program.

The purpose of this study was to investigate the moderating effect of parent's neglectful behavior on children's irrational beliefs and their style of expressing anger. The subjects consisted of 354 5th and 6th grade elementary school children. The instruments used were the Multidimensional Neglectful Behavior Scale (Straus et al., 1995), the Irrational Belief Scales (Lee, 2004), and the Anger Expression Scale (Spielberger, Krasner, & Solomon, 1988). Data were analyzed by means of both descriptive statistics and hierarchical regression analysis using the SPSS 18.0. The result of this study indicated that there were significant correlations between parent's neglectful behavior and the irrational beliefs and style of anger expression exhibited by the children concerned. Hierarchical regression analysis indicated that, the effects of children's irrational beliefs on their anger was moderated by parent's neglectful behavior. The effects of children's irrational beliefs on their anger control was also moderated by parent's neglectful behavior. In conclusion, parent's neglectful behavior has a moderating effect upon a child's irrational beliefs as it relates to the style of anger expression as exhibited by their children.

This study analyzed the spatial hierarchy of Hyangkyo architecture. Hyangkyo was built on the basis of Confucianism. The results are as follows; 1) The spatial hierarchical construction responding to the site. The arrangement style of hierarchical construction changed according to the site. This is the reason that the hierarchy of Confucianism has the relationship of the upper class and the lower class, high and low of position, high of right and low of left, and the theory of division based on topography. 2) The hierarchical construction responding to the arrangement style. Buildings were hierarchically constructed according to the site of the architecture. This is the result of hierarchy. In conclusion, the spatial hierarchy means that Hyangkyo architecture had been built according to an order on the basis of Confucianism.

The purpose of this study was to investigate the effects of socio-demographic variables, adult attachment and emotion regulation style on psychological well-being of university students. We conducted a survey on 318 university students in Cheongju-si and Hongseong gun. T-test, Pearson' productive correlation, hierarchical regression analysis were used. The results were as follows: First, there was a significant difference in emotion regulation style according to university student's sex. In other words, females used more support-seeking style than males did. Second, male university students' psychological well-being was high at more active style, less anxiety attachment and avoidant/distractive style, older students, less avoidance attachment, and higher economic status. Third, female university students' psychological well-being was high at less avoidant/distractive style and more active style, older students, less anxiety attachment, and more support-seeking style. In conclusion, emotion regulation style was the strongest factor to increase university student's psychological well-being among other variables. The implications and limitations of this study were discussed.

Objective: The purpose of this study was to examine the relationship among perceived mothers'psychological control, affectionate-rational parenting and children's attributional style. The main and interaction effects of psychological control, affectionate-rational parenting on children's attributional style were also explored. Methods: The participants of this study were 253 children from elementary schools located in Seoul and Incheon. Data were analyzed through Pearson's correlation, and hierarchical regression using SPSS 22.0. Results: The major findings of this study were as follows. First, children's attributional style for negative events was positively associated with psychological control but negatively associated with affectionate-rational parenting. Moreover, attributional style for positive events was positively associated with only affectionate-rational parenting. Second, affectionate-rational parenting significantly influenced children's attributional style for both negative events and positive events. Finally, significant interaction effects of psychological control and affectionate-rational parenting on children's attributional style for negative events were observed. Conclusion/Implications: This study revealed that mothers' psychological control and affectionate-rational parenting are important factors in explaining children's attributional style. Such results could be used as an effective resource in developing parent education programs or intervention programs for attributional style.

This research aims to explore the relationships between 'teamwork skills' (often called team activity competence) and 'thinking styles' of engineering students in Korea, and to provide an explanation for the application of team-based environment as well as for the increase of teamwork skills. Teams and team activity are pervasive in today's organization and there has been relatively much research on teamwork skills and its related factors. However, to date, little attention has been paid to the teamwork skills, essential factor in team-based environment and its relationships with thinking styles. This study was conducted with 383 engineering students at P University, and students' teamwork skills as well as thinking styles have been measured before and after team-based learning class (hereafter TBL). Our findings show that firstly, there was a significant increase of teamwork skills between before and after TBL class. Second, team activity competence was found to have a higher correlation with most of creativity generating styles (i.e. legislative, judicial, hierarchical and global styles). Third, hierarchical style was found to influence team activity more than other components, and also legislative, external, global and judicial styles contributed to team-based activity. These findings are expected to provide an explanation for the application of thinking styles in team-based environment and will be useful for the improvement of related courses in engineering school.

We have investigated the Intelligent Shift-map Module(ISM) to improve some problems in the conventional Automatic Transmission(AT) for automobiles. The typical AT lacks flexibility regarding the shift point because it does not consider the driver's habits and inclinations. Also it often is occurred phenomenon like kick-down. Therefore, we designed a decision module which considers the driving style of the individual driver. The driving style was determined by the inclination of the driver and the driving technique using actual automobile data. The Hierarchical Neural Network(HNN) was applied in generating an intelligent shift map with Multilayer Neural Network(MNN). It was found that the proposed ISM provided a suitable shift point and time because the necessary toque and velocity of the automobile was considered along with the driving style of each driver when designing the ISM.

This study examined the thinking styles of scientifically gifted students on the basis of Sternberg's theory of mental self-government, and the relationship between thinking styles and self-regulated learning ability of the students and their scientific inquiry ability by the different types of thinking styles. 110 middle school students who belonging to the university science-gifted education center participated in this study. 13 thinking styles were postulated that fall along 5 dimensions which are functions, forms, levels, scopes and leanings of the mental self-government. Scientifically gifted students responded to the Thinking Style Inventory (TSI) that standardized Korean version, Self-regulated Ability Inventory and Test of Science Inquiry Skills Inventory (TSIS). The results indicated that scientifically gifted students prefer legislative, liberal, external, hierarchical and judical thinking styles, rather than conservative style. This result also showed that subscales of thinking styles were significantly correlated with self-regulated learning ability and scientific inquiry ability. The legislative style, hierarchical style, local style and liberal style were significant predictors of self-regulation learning ability. The legislative style was significant predictor, whereas oligarchic style was negative predictor of scientific inquiry ability. The results of k-means clustering analysis and MANOVA showed that the self-regulated learning ability and scientific inquiry ability were significantly correlated with the pattern and level of thinking style.
