The purpose of this study was to investigate the middle school students' perception and their learning satisfaction in SMART learning based science instruction. Three types of modules on the solar system and lunar phases unit at the middle school level were developed and lessons on each module were taught to 207 student participants. All participants were provided with tabletPC(iPad2) with iOS5 installed, and using astronomy app Solar Walk, mirroring function, QR code, and Google Presentation, the lessons were carried out both in classroom and at home. The instrument for assessing students' perception on the SMART learning-based instruction was developed based on 4 factors including Self-directed, Motivation, Adaptiveness, and Technology Embedded, with a Likert scale from 1-5 on 20 items. The learning satisfaction survey instrument was originally from Keller's work (1987), and its test items were adapted and modified. To reveal the perception and learning satisfaction about SMART learning-based science lessons, the participants were comparatively analyzed by gender and science achievement levels. Results indicated that male students showed positive perception for the SMART learning-based instruction. Group with higher science achievement scores showed more positive perception of the SMART learning-based instruction in terms of Self-directed and Motivation factor. Also, the learning satisfaction of male students was higher than female students and group with higher academic ability more satisfied with the SMART learning-based instruction than the low group. The results provide implications for future development of programs and help set a direction of increasing the use of a SMART learning-based science in school.
Objectives: The main purpose of this study was to investigate the possible differences in sleepiness, performance, and body temperature during the night between morning(M) and evening(E) type subjects. Methods: After a survey study, to verify the validity and reliability of the Korean translation of the Home' and $\ddot{O}stberg's$ Morningness-Eveningness Questionnaire(1976), 8 extreme M-type subjects(3males, 5 females) and 8 extreme E-type subjects(3 males, 5 females) were selected from the university student population who had participated in the survey study. All subjects underwent sleep latency test and a battery of performance tests at intervals of 2 hours through the night, from 23:00 to 07:00. Oral temperature of each subject was taken every hour from 21 : 00 to 8 : 00. Between the testing times, the experimenters ensured that subjects remained awake. Results: More profound sleepiness was found in the M-type compared to the E-type throughout the night, with significant differences in sleepiness occuring at 23:00 and 01:00 hours. Overall performance efficiency tended to be lower through, the night in the M-type than in the E-type on all tests. A difference in time of temperature minimum between the two types was not noteworthy. Rather, there appeared to be a substantial difference in temperature level during the declining phase, with the temperature of the M-type being lower than that of the E-type. Conclusions: These results indicate the existance of a temporal relationship between sleepiness, perfonnance and body temperature during night work. Since the M-type exhibited greater sleepiness and lower performance efficiency overnight than the E-type, it may be assumed that the E-type is more suitable for and tolerable to night work. There was some discussion of the limitations in generalizing these results together with some suggestions for future studies.
The purpose of this study was to develop and validate Korean version of Deaf Acculturation Scales(DAS). Pilot items were made a faithful translation of the Acculturation Scales of Maxwell-McCaw and Zea (2011) and were modified for Korean Deaf people. The Scale involves two dimensions, in order to measure the acculturation of Deaf people; Deaf acculturation and hearing acculturation. Using factor analysis, we developed a Korean version of DAS consisted of twenty-five items for Deaf acculturation dimension and twenty-five items for hearing acculturation dimension. These analysis supported the four factors of Deaf acculturation dimension and the five factors of hearing acculturation dimension. Reliability, assessed by Cronbach's ${\alpha}$, was .93 for Deaf acculturation and .93 for hearing acculturation, respectively, which confirm the Koran version of DAS. Construct validity was demonstrated through correlation with Deaf acculturation-related variables: age, age of Deafness, Degree of hearing loss, American Sign Language ability, and lip-reading ability. Criterion validity was supported by correlation with Collective Self-Esteem Scale. Limitation and implication of this study and direction for future research were discussed.

Objectives : This study was done to develop Korean form of Reynolds' SIQ-JR(Suicidal Ideational Questionnaire-Junior). Through this study we evaluated reliability and validity of Korean form SIQ-JR. Methods : Subjects were 1,160 middle and high school students and 114 adolescent psychiatric patients. SIQ-JR and 8 self-reporting scales highly related with suicidal ideation and suicide behaviors were applied to them. Results : In reliability aspect of Korean form of SIQ-JR, internal consistency, test-retest reliability and item-total correlation were statistically significant results. In factor analysis, concerning about other person was extracted as a indepenedent factor. This results reflect our cultural characteristics. There were statistical differences of SIQ-JR scores in groups by sex and age. Clinical group showed significantly(P<0.01) higher scores than general population. Among the 8 suicidal relating scales, depression(r=0.42), aggression(r=0.36), trait anxiety(r=0.35), and anger-in(r=0.31) were highly related with suicidal ideation but impulsivity and hopelessness were not significantly related with suicidal ideation. Conclusion : Korean form of SIQ-JR was useful instrument in reliability and validity. We hope that this instrument widely used in school mental health, community psychiatry and clinical setting for screening tool.

This study aimed to evaluate the relationship between parenting styles and childhood dental caries using a sample of 3 to 6 years old children in Korea. The subjects were 158 children aged 3 to 6 years old and their parents in Korea. The parenting styles were divided into three groups (authoritative, authoritarian, and permissive) using a translated version of the Parenting Styles and Dimensions Questionnaire (PSDQ). Among the 353 parents/child dyads, 158 questionnaires were returned. Authoritative parenting style was the majority (95.6%), followed by authoritarian (3.8%), and permissive (0.6%). There were no statistically significant differences between dental caries and parenting styles. The mean of dft index in authoritative group was lower than others. In the authoritative domain, the higher the authoritative tendency, the lower the dft index. Overall, authoritative parenting styles resulted in low rates of dental caries for the children. The stronger the authoritative tendency of the parents, the lower the experience of dental caries in the children. Therefore, parenting styles were likely to affect the oral health of a child, but it seemed necessary to supplement the evaluation tool to evaluate the parenting styles.
The purpose of this study was to develop a group bibliotherapy program for improvement of elementary school students' self-esteem and to examine its effects. The subjects in this study were 20 children who were selected from 120 sixth graders at H elementary school in Gwangju Metropolitan city. They are randomly allocated at experiment group(n=10) and control group(n=10). Twelve sessions were administrated to experiment group for group bilbiotherapy and each session had run 40 minutes. Data were collected through the self-esteem inventory which was originated from Coopersmith's Self-Esteem Inventory(1967) and Chang(2001) translated and modified and the researcher remodified for this study. The collected data were analysed through ANCOVA. Research results were as followings. First, the experimental group showed a significant increase in the level as compared with the control group. Second, the experimental group showed significant increase in the level of general Self-Esteem, social Self-Esteem, homely Self-Esteem, but showed no significant increase in the level of schoolwork Self-Esteem as compared with the control group. The results showed that the group bibliotherapy has significant effect on the improvement of elementary school students self-esteem.
This study was to develop new psychological capital scale for high school students attending a technical high school specialized in invention and patent education, and to examine validity and reliability of the new psychological capital scale. Of the 400 high school students attending a technical a technical high school specialized in invention and patent education in a Province, Korea, 388 completed and returned the questionnaires. PCQ (Psychological Capital Questionnaire)-24 items version was modified to measure psychological capital of them. By conducting confirmatory factor analysis, the final 19 items were selected. The Cronbach's alphas of the final version were ranged from .723 to .871. Convergent validity was supported through correlations among the sub-scales of the final version of PCQ, creative intelligence, creativity, and academic efficacy. Criterion-related validity was supported by mean differences on 4 sub-scales of psychological capital (i.e., self-efficacy, hope, resilience, and optimism) between two groups (i.e., prize-winning experiences for invention or academic achievement).
This study investigated the effects of the extension activity with fifty famous paintings on the improvement of young children's creativity and emotional intelligence. A total of thirty-one preschoolers participated in the study. There were a total of 15 preschoolers in the experimental group and 16 preschoolers in the comparison group. The measuring device of creativity was the Figural Tests of Torrance Tests of Creative Thinking (TTCT:Firural). And the measuring tool of emotional intelligence was the 'Emotional Intelligence Evaluation Tool for a Child by Teacher's Composer' developed by Younja Lee, Jongsook Lee, and Eunsu Shin (2000). To improve the accuracy of the experimental results from the post-test, a covariance analysis (ANCOVA) was conducted with the pre-test scores as covariate and the post-test scores as dependent variables. The statistical work with collected data was carried out by using PASW 18.0. The experimental group which participated in the extension activity with famous paintings showed improvement in the subordinate elements of creativity such as fluency, originality and abstraction of titles. Between the experimental group and comparison group, there was a meaningful difference statistically. The experimental group was also positively affected on all the subordinate elements of emotional intelligence such as awareness and expression of emotions, improvement of thinking by emotions, using ability of emotional knowledge, and control ability as the reflection of emotions. Through the activity, children became to respect the opinions of other friends.
Objectives: Narcolepsy is characterized by excessive sleepiness, cataplexy, sleep paralysis and hypnagogic hallucination. As there have been few researches on narcolepsy symptomatology in adolescents, we examined gender differences and prevalence of narcolepsy tetrad among students attending high school. Methods: Total 20,407 subjects, ages 14-19 years filled out Ullanlinna Narcolepsy Scale (UNS). Subjects whose UNS scores were equal to or more than 14 were interviewed by telephone using semi-structured questionnaire. Variables included questions to evaluate tetrad of narcolepsy. Results: UNS scores were higher in female than male ($11.1{\pm}5.2$ vs. $9.6{\pm}4.5$, p<0.001). Subjects scoring the UNS equal to or more than 14 were 4,535 (22.2% of all the participants), more frequently observed in female than in male (p<0.001). Excessive daytime sleepiness, cataplexy-like symptoms, sleep paralysis and hypnagogic hallucination in subjects of UNS ${\geq}14$ were significantly higher in female subjects than male ones. However, no significant gender difference was observed in the frequencies of severe sleep attack and cataplexy-like symptoms. Sleep paralysis was most frequently reported during sleep. There was significant correlation between sleep paralysis and hypnagogic hallucination (r=0.235, p<0.01). Conclusions: Our findings were that female adolescents complained more frequently narcolepsy symptoms than male subjects. Female adolescents might be more sensitive than male ones to physical complaints such as sleepiness or muscle weakness.
The purpose of this study was to investigate the effect of education of natural disaster on eco-friendly attitude of children in integrated class in the lower grades in elementary school. For the above mentioned purpose, 2 children with developmental delay and 45 general children enrolled in two integrated classes in the first grade in C Elementary School located in G City. The class that wanted to participate in this program was designated as an experimental group and the other class as a comparative group. Total 18 times of session of experimental treatment were performed during the second semester of the first grade. The effect of education of natural disaster was measured by using the tool revised and adapted by Heoh, Yun Jeong on the basis of CATES-PV designed by Musser and Diamond. As results, it was appeared that education of natural disaster was effective to increase eco-friendly attitude of children in integrated class in the lower grades in elementary school. The results that ability and attitude which were goals of the current education related to environment such as love and concern for animals and plants, life respect consciousness, preference for natural environment rather than artificial environment, conservation of nature and resources saving etc of children who received education of natural disaster suggest necessity to rethink the meaning and scope about education of natural disaster for Korean children in the preset.
