The inactive student rate is becoming a major problem in most open universities worldwide. In Indonesia, roughly 36% of students were found to be inactive, in 2005. Data mining had been successfully employed to solve problems in many domains, such as for educational purposes. We are proposing a method for preventing inactive students by mining knowledge from student record systems with several state of the art ensemble methods, such as Bagging, AdaBoost, Random Subspace, Random Forest, and Rotation Forest. The most influential attributes, as well as demographic attributes (marital status and employment), were successfully obtained which were affecting student of being inactive. The complexity and accuracy of classification techniques were also compared and the experimental results show that Rotation Forest, with decision tree as the base-classifier, denotes the best performance compared to other classifiers.

In order to investigate school libraries' educational impact, two different surveys were conducted. One examined students' school library use in general, including the frequency, purpose, and effect of their library use, and the relative importance of the library in their campus life. The other examined and analyzed their perception of the benefit of the school library to determine if any differences exist among the following three levels: 1) libraries staffed with a dedicated teacher librarian, 2) libraries without a dedicated teacher librarian but active, and 3) libraries without a dedicated teacher librarian and inactive. The questionnaire to survey student's perception had 38 statements, The surveys on student's library use and their perceptions indicated that school libraries benefit the students' reading activities the most. The overall mean of the perception was 3.24(in 5 scales), There were distinct differences among the three levels of school library conditions: the mean for libraries with a teacher librarian scored highest at 3.37, libraries without a teacher librarian but active scored second highest at 3.20, and libraries without a teacher librarian and inactive scored lowest at 3.16. The levels of school library condition suggested direct links to the educational effect on students' achievements.

Purpose: The purpose of this study is to survey on the influence of the laughing program on elementary school students' self-esteem and stress coping behaviors. Methods: In total, 43 children (grade 4~6 students) were recruited for self administered questionnaire. Questionnaire was composed of general characteristics, self-esteem, and stress coping behaviors. Ten week course of laughing program was scheduled to the Experimental group, meanwhile no program was given to the control group. Results: The median self-esteem scores in the experimental group was increased from 30.05 to 34 (Z=-2.375, p<.05). Meanwhile control group did not show significant change. The median inactive/avoidant coping scores in the experimental group was decreased from 10 to 9 (Z=-2.028, p<.05). Meanwhile control group did not show significant change in any items of stress coping behaviors. Conclusion: Laughing program may be helpful to improve stress coping behaviors through reducing inactive/avoidance coping as well as to strengthen self-esteem, especially among participants who had low self-esteem before the intervention.

This study has been conducted on the nonequivalent control group pretest-posttest design in quasi experimental basis and newly born premature infants from intensive care unit of G Medical University Hospital in Inchon Metropolitan were selected in two groups of 21 infants each. The first group for experimental and the other for control. Data has been collected form October 30, 1997 to August 29, 1998. For the experimental group tactile and kinesthetic stimulation was applied 2 times a day for 10 days(10 : 00~11 : 00 hours in the morning and 17 : 00~18 : 00 in the afternoon). As a weight weighing instrument. electronic indicator scale(Cas Co. korea) was used. To determine urine cortisol concentration level in stress hormone, radio immune assay method was used. And high performance liquid chlomatography was used to determine urine norepinephrine, concentration level To determine behavior status, tools developed by Anderson et at(1990) and remodeled by Kim Hee-Sook(1996) were used. Collected data were analyzed with the SAS program using x$^2$-test, student t-test, repeated measures ANOVA and paired t -test. The result were as follow. 1. As for the daily weight gain. the experimental group showed first change in weight and this group also showed higher weight in the average weight than the control group. Statistically, however, there was no significant factor between the two group. 2. The cortisol concentration in urine showed decrease in the experimental group norepinephrine concentration in urine showed increase in both experimental and control groups. No statistical significance was shown between the two groups. 3. In the aspect of behavior status. the experimental group showed statistical significance by showing inactive in the state of alert and conversion to a positive state than the control group. In conclusion, the sensory stimulation in this study showed a positive aspect through there was no statistical significance in the weight gain and urine stress hormone concentration. In the behavior status, there was statistical significance in the frequency of staying inactive in the state of alert and conversion to a positive state.

This study explores aspects of Vietnamese students' acculturation and acceptance behavior of K-fashion, based on the theory of planned behavior (TPB). In-depth interviews were conducted with 8 Vietnamese international students in Korea. The results of the study firstly indicate that K-fashion acceptance behavior of Vietnamese students reflected eight values of K-fashion, two motives of behavior, and two types of K-fashion acceptance behavior. Vietnamese students generally displayed a favorable attitude toward K-fashion. They all switched to K-fashion styles and actively showed their styles through SNS. Second, there was a difference in K-fashion behavior depending on whether the motivation for acculturation was of an active or inactive nature. The distinction between these two groups was determined by applying behavioral reasoning theory (BRT). Students whose motivation for learning Korean was an interest in Korean culture were characterized by active behavior in adapting to Korean culture, while those whose motivation for learning Korean was for strategic reasons, such as finding a good job, exhibited inactive K-fashion acceptance. This study has academic significance in that it enhances the understanding of Vietnamese consumers through the K-fashion acceptance behavior of Vietnamese students in Korea. Vietnamese students who actively embrace K-fashion play an important role in spreading K-fashion, so it could be beneficial to establish a strategy for promoting K-fashion in collaboration with them.

Purpose: The purpose of this study was to examine the effects of sensory stimulation on premature infants. Method: Thirty three premature infants admitted to NICU of D University Hospital in C city were randomly assigned in two groups (Experimental group: 16, Control group:17). For the experimental group, tactile and kinesthetic stimulation developed by Dr. Field was applied 2 times a day for 10 days. Behavioral state was measured using the Anderson Behavioral State Scale (ABSS). Heart rate, respiration, and oxygen saturation were obtained for each infant before and after sensory stimulation. Hypothesis testing was done using the $\chi$$^2$- test, student t-test, and repeated measures of ANOVA. Result: Hypothesis 1: There was a significant difference in the daily body weight gain between experimental and control group (F= 40.77, p= .0001). Hypothesis 2: There was a significant difference in the frequency of 'inactive awake state' between two groups ($\chi$$^2$= 39.778, p= .001). Hypothesis 3: There were significant differences in the mean of heart rate and $O_2$saturation between two groups (t= -2.174, p= .037; t= 3.080, p= .005). However, there was no significant difference in the mean of respiration rate between two groups (t= -1.966, p= .581). Conclusion: The effectiveness of a sensory stimulation on weight gain and behavioral state in premature infants was supported. Further study is recommended to develop a sensory stimulation method as an independent nursing intervention for premature infant.

This study investigated 15 science teachers' perception and practice on free semester and science assessment. We analyzed frequencies of teacher choice for closed questions and used constant comparative method for teacher description and individual interview. Most teachers determined a low ranking for changes in assessment methods and mentioned a lack of objectivity on free semester assessment, unsystematic free semester assessment, and more importance on student activity and interest in science instruction. Most teachers understood process-based assessment as a direction of free semester assessment and teachers mentioned positive aspects for students or teacher difficulties dependent on their perception on process-based assessment. Half of the teachers failed to implement student self-assessment and student peer-assessment due to subjectivity and complexity. Some teachers did not provide feedbacks to students due to a lack of time and did not use certain assessment methods due to a lack of knowledge of the assessment. Teachers who did not have an experience of discussions in a teacher learning community mentioned reasons regarding a small number of the same grade teachers and inactive attitude of colleagues. Teachers who did not participate in professional development programs mentioned a lack of teacher understanding of free semester, participation of the teacher in charge, and teacher choice of participation as reasons.
