  • Purpose: The purpose of this study was to investigate the influence of breakfast characteristics of university students on their self-regulated learning, attentional control, and fatigue in order to provide-basic data for establishing desirable eating habits, self-regulated learning skills using attentional control, and advisable learning habits of university students. Method: The level of fatigue was estimated using the Visual analogue scale (VAS) and Critical flicker frequency (CFF). Attentional control was measured using the Attentional Control Questionnaire (ACQ) adapted by Yoon. Self-regulated learning was surveyed by the Self-Regulated Learning Test developed by Chung. Data from atotal of 142 university students were collected from November 30 to December 9, 2011. Result: 69% of the subjects skipped their breakfast. Attentional control has a negative correlation with fatigue (r=-.179, p=.033) and a positive correlation with self-regulated learning (r=.352, p<.001). The multiple regression model of self-regulated learning consists of attentional control (t=3.218, p=.002), commuting time (t=-3.076, p=.003), understanding the importance of breakfast (t=-2.413, p=.008), and skipping breakfast(t=-2.195, p=.030) and its R-square was 21.8%. Conclusion: Learning efficiency of university students should be improved by means of attentional control, which is related to self-regulated learning. Also, it is essential for university students to establish healthy lifestyles including regular eating habits and attentional control, in order to improve their self-regulated learning.

  • This study examined the moderated effects of self-control on the relationship between elementary school children's excessive use of the Internet and their stress levels. The participants were 403 elementary school children from Chungnam-do. The instruments used were the 'Internet Addiction Autodiagnosis Scale (K-Scale)', the 'Stress Scale' and the 'Self-control Rating Scale'. The collected data were analyzed by t test, F test and the Scheffe test for a post hoc test, Pearson's partial correlation and stepwise multiple regression, and Cronbach's ${\alpha}$ for reliability by SPSS program (17.0 version). The results were as follows : First, it was found that there were significant differences in terms of excessive use of the Internet, stress levels, and self-control by gender, grade, academic achievement, the beginning year of first Internet access and the number of hours of Internet usage hours per day. Second, there were significant positive correlations between excessive use of the Internet (r = .40, p < .001) and stress levels (r = .44, p < .001) and the immediate satisfaction of self-control. Finally, the immediate satisfaction of self control was seen to moderate the relationships between the total scores for the excessive use of the Internet and stress levels and between withdrawal of excessive use of the Internet and the accompanying stress levels.

  • A fuzzy dynamic learning controller is proposed and applied to control of time delayed, non-linear and unstable chemical processes. The proposed fuzzy dynamic learning controller can self-adjust its fuzzy control rules using the external dynamic information from the process during on-line control and it can create th,, new fuzzy control rules autonomously using its learning capability from past control trends. The proposed controller shows better performance than the conventional fuzzy logic controller and the fuzzy self organizing controller.

First, self-concept point of experiment group students who execute self-growth program will be improved is meaning than self-concept point of control group students. Second, peer-relationship point of experiment group students who execute self-growth program will be improved is meaning than peer-relationship point of control group students. Third, effect that self-growth program gets to self-concept may be meaning difference according to sex. Fourth, difference that impact that self-growth program gets in peer- relationship is meaning according to sex may join. Chose fifth-year student 2 class 68 people (experiment group n=34, control group n=34) in I primary school locating to Jeonrabuk-do Iksan-si to verify above construction for study target. Disposal about experiment group executed over 10th for 60-80 minute 2 times in a week because investigator uses reconstructing self-growth program with virtue research paper such as learning program for own growth of Lee-Hyeong-Deuk (1998). In order to verify the effect after experiment, 1 collected materials for estimation by providing the subject children with questionaires about self-concept and peer-relationship before and after the experiment, and then analyzed the average differences in number of marks between the experiment group and the control group before and after the experiment through and by using One-Way ANOVA, and SPSS 11.0 program. The following is the result what I obtained from the above study. First, there was significant difference is between average difference before and after of experiment group and control group which execute self-growth program in self-concept elevation ($F_{(1,66)} =28.734$, p <.001). From the sub-variable, there was significant difference in academic self ($F_{(1,66)}=6.423$, p<.05), Social Self ($F_{(1,66)}=48.331$, p<.001), Physical Self ($F_{(1,66)}=11.074$, p <.01), sentimental self ($F_{(1,66)}=9.402$, p <.01) Second, there was significant difference is average difference before and after of experiment group and control group which execute self-growth program in peer-relationship promotion ($F_{(1,66)}=24.109$, p <.001). From the sub-variable there W3S Significant difference in trust ($F_{(1,66)}=14.507$, p<.001), respect ($F_{(1,66)}=15.271$, p <.001). Third, there was expose that significant difference does not exist in average self-concept before and after by sex of experiment group which executes self-growth program, and was not shown significant difference in sub-vairable. Fourth, there was expose that significant difference of whole peer- relationship and in respect of sub-variable in average peer-relationship before-after by sex of experiment group which execute self-growth program, but significant difference did not appear in trust. Could get conclusion that self-growth program is effect in elementary school student self-concept elevation and peer-relationship promotion according to these study finding, and confirmed possibility that self-growth program may contribute to change emotional special quality of children positively in education spot.

  • The purpose of this study was to investigate self-esteem, body image, body cathexis and body attitude of female middle school students. A total of 298 subjects were included in this study. Subjects were classified into weight control group and a non weight control group. As a result of analyzing body shapes satisfaction was higher in the non weight control group 2.83 than in the weight control group 2.28 (p<0.001). The weight control group revealed lower body satisfaction than the non weight control group. The result of the reason for weight control was the ratio of 'weight loss' 84.6%, respectively (p<0.001). Factors impacting physical image of female middle school students were analyzed as friends (3.46), internet (3.22), and TV (3.13). Results suggest that educational program should be combined with a positive emphasis on physical image and self-esteem for female middle school students. Also, there was a high correlation between body weight and self-esteem. Results indicate that female middle school students are interested in weight loss with the wrong body image. Therefore, female middle school students should be provided with an educational approach to such issues so that they have a realistic perception of their body and form realistic values about self-esteem and body.
