  • The purpose of this research is to know what factors have impacts on their risk perception and attitude in risk communications. This research shows the research findings that the determinant factors of risk perception are the possibility to control the risk, benefits of recognition, the specialty of risk management, and the usefulness of information about the risk. And also the results have shown that the determinant factors of risk attitudes are the possibility to control the risk, the understanding of science and technology, the familiarity with the risk, the usefulness information about the risk, the accuracy of information, and the initiative in the protection of citizens from the risk. As the results have indicated, common determinant factors are the usefulness of information about the risk and the possibility to control the risk. Both of them that affect risk perception and attitudes on electromagnetic waves are important factors in risk communication research. Therefore this study shows that what factors suppose to be considered important in risk communication process about risk of electromagnetic waves.

  • This study aims to identify the effect of music psychotherapy on motivation for learning in the underachieving student. The study divided nine children into two groups and placed four children in a test group and five children in a control group. After conducting a pre-test, the researcher performed music psychotherapy with the four children in the test group for about 12 weeks, twice a week, totaling 18 sessions. Quantitative data were measured in pre-and-post tests using Mann-Whitney's U-test, and the effects of the therapy were analyzed using Wilcoxon. The findings of this study were as follows. Music psychotherapy was shown to be effective for improving all types of motivation for learning in underachieving students (p < .001). This was shown by assessing improvements in the experimental group across four sub-areas of motivation for learning (p < .1), and directly measured by examining the subjects' lingual responses related to motivation for learning. These results demonstrate that music psychotherapy is effective for enhancing motivation for learning in underachieving students.

  • The purpose of this study was to investigate the effect of computer based cognitive rehabilitation program on the generative naming. Twenty - one patients were assigned to the CoTras program and eight were treated with traditional face - to - face language rehabilitation such as paper and table activities. The experimental group and the control group performed sequential language recall memory training, association memory recall training, language categorization memory training, and language integrated memory training for 12 weeks. The Welch's robust ANCOVA showed significant differences in mean fluency and MMSE-K changes (p<0.05). On the other hand, phonemic fluency increased significantly after 12 weeks of treatment compared to baseline in both experimental and control groups, but there was no statistically significant difference between treatment groups. The results of this study suggest that the computer based cognitive rehabilitation program may be more effective in improving the semantic fluency than the conventional cognitive-linguistic rehabilitation.

  • Problem-based Learning (PBL) has been known as an effective strategy for dealing with various aspects of education such as the enhancement of students' motivation, interest in subjects, academic achievement, and cooperative abilities. However, PBL has not been widely implemented in secondary schools. The purpose of this study is to investigate secondary school teachers' perception of problem-based learning and their way of applying it. Data was collected through semi-structured interviews with nine secondary school teachers. Five of them had experience in implementing PBL, while four of them had interest in using PBL but had not yet had the experience. Different concepts were extracted and categorized. Nvivo 2.0 was used for analysis. The results were as follows: Changes in student attitude toward class, improvement on cooperation with others, self-regulated learning skills, and satisfaction from students' positive comments on PBL enabled teachers to become more enthusiastic and positive toward PBL. The stress of developing proper problems and the enormous amounts of time and efforts required in using PBL were shown as barriers for teachers in implementing PBL. However, some negative perspectives about PBL changed into positive after teachers experience PBL. By examining each teacher's way of implementing PBL, several teaching strategies suitable to their school systems were suggested.

  • The purpose of this meta-analysis was to address two questions: (1) To what extent are types of child abuse related to psycho-social maladjustment of the abused? (2) Do relations found in this study vary by the gender, sample size, year of publication, types of publication, and respondents' age? The materials of this study were based on 14 variables obtained from 104 published and unpublished (doctoral disserations and master's theses) research papers over a span of 26 years(1990-2016). Child abuse related variables were categorized into physical abuse, emotional abuse, neglect, and abuse while psycho-social maladjustment grouped as internal (anxiety, depression, withdrawal, and anxiety/depression) and external problem behaviors(aggression, problem behavior, and delinquency). Major findings were: Medium effect size of emotional abuse, abuse, physical abuse, neglect on psycho-social maladjustment among the abused were calculated. Emotional abuse was highly related to every internal and external problem behaviors. Neglect was found to have higher effect size in external problem behaviors than internal problem behaviors. Publication types moderated the association between types of child abuse and internalization while year of publication, number of samples and publication types showed moderation effects on the relation between types of child abuse and externalization. Finding suggest that future studies on child sexual abuse and those on intervention outcome are required and use of well validated instruments are essential.

  • The current study analyzed the relationship between expression type of humor ads and their advertising effects and the differences in advertising effects by expression type according to temperament as categorized by the Myers-Briggs Type Indicator (MBTI). Expression type of humor was classified into arousal-, incongruity-, and superiority-type humor ads. Advertising effects were measured by consumers' cognitive, affective, and conative responses. Three ads were created based on expression type of humor. A personality type, as measured by the MBTI, was categorized into four types of temperament, namely SP, SJ, NF, NT and used as moderating variables. As a result, the advertising effects varied according to the expression type of humor advertising. Interaction effects between ad expression type and temperament on ad feeling and ad preference were also found.
