This research aims to analyze the changes in participants' capacity (problem-solving ability and self-leadership), humanity (self-efficacy), and global network (intercultural sensitivity) as performance indicators and the 'effectiveness of personal characteristics' of the World Friends IT Volunteers program. To do this, the study conducted a pre-test and a post-test on 364 participants of the World Friends IT Volunteers program. The collected data is investigated through ANCOVA using covariates, driven from the prerest results. The results of this study represent that meaningful improvements have been identified in problem-solving ability, self-leadership and intercultural sensitivity since the operation of the program. Regarding the personal characteristics, performance in the female group improved more than the male group in terms of intercultural sensitivity, whereas the male group showed better performance on self-efficacy than the female group. In addition, the group with a high level of English proficiency showed more progress on intercultural sensitivity and self-leadership than the English-beginner group. Besides, the group who had an experience of short-term stay overseas showed moderate improvement on problem-solving ability and intercultural sensitivity when compared to other groups. The group who had lived overseas for a long-term showed better indicators on intercultural sensitivity. Also, self-efficacy of the leader group was more noticeable than that of the member group.

The purpose of this study was to examine the effects of formative assessment with detailed feedback on students' science achievement, attitude, and interactions between the teacher and the students. For the study, 133 seventh graders were selected from a girl's middle school in Seoul, and assigned to the experimental and the control groups. The duration of the treatment was over a period of nine weeks. In the experimental group, detailed feedbacks on the solution, teacher's comments on the results, and relevant references were provided after each formative assessment. However, only the answers were presented in the control group. Prior to instructions, a achievement and a attitude tests were administered. After the instructions, follow-up tests which were similar to the pretests were also administered. The results showed significant difference between the two groups in science achievement. It was found that the usage of formative assessments with detailed and supportive feedbacks was more effective in stimulating students' interest, raising their confidence in the subject, increasing their participation, as well as reducing their anxiety. The results also strongly indicated that detailed feedbacks were more effective in improving the interactions of the teacher and the students. The results strongly suggest that formative assessment utilizing detailed and supportive feedback is a necessary component of effective science teaching and learning.
Students with learning disability have difficulty with attention and academic achievement Music can be an effective tool to enhance level of participation. The purpose of this study is to examine how much can be structured to enhance the attention span and related academic skills needed to achieve educational goals. The study has implemented structured music therapy sessions for three middle school students with learning disability. They participated in 20 sessions which were 30 minutes in length for ten weeks. The implemented music therapy sessions were designed using songs, playing, and listening to music. In order to test their level of attention, Frankfurter Aufmerksamkeits-Inventar(FAIR) Attention Test is implemented and Conners' Comprehensive Teacher's Rating Scale(CTRS-10) are used on the week before and after music activities. Also videotaping is used so as to analyze how correctly they do their task and how the correctness is changed period by period and to evaluate how often for ten minutes they make an eye contact with their teacher. The conclusions of this study are as follows: Firstly, the organized music activities have a positive affection on improving the attention of three middle school students who have learning disabilities. Fair Attention Test shows that they can do their task with more accuracy than in the previous period. Secondly, three students of this study improved their attention and made an eye contact more often than before this study, which is revealed through the analysis of the pre and post test results evaluated by CTRS-10. The results of the study indicate that structured use of music in various level of activities can help students to enhance attention span and the related academic skills.
Mentally disable children feel as failure because they have difficulty in restricted and undifferentiated communications with others. It also makes the counter-partner feel frustrated. Therefore, in the aspects of language acquirement and communication activities, it is essential to let the disable children learn and communicate voluntarily. Music provides the unthreatening and interesting stimulus as non-language communication vehicle. Musical experiences for mentally disable children's are multi-stimulating experiences that make a positive influence in speech and language development and development of variety of talents. There are many communication intervention and method to treat the mentally disable children. One of the most effective treatments for mentally disable children to acquire communication techniques by expressing the language more naturally and joyfully is the musical therapy. This study analyzes children's communication technique referring to response action and attempt action through video tape observation. Also, this study measured the receptive and expressive language by PRES(Preschool Receptive-Expressive Language Scale) as a test tool in order to examine the pre-post language ability for respective children as pre-post period of therapy activity. First result of this study showed that music therapy with song was effective for mentally disable children in enhancing the communication techniques centered with communication response and in attempt action by increasing the communication action incidence. Secondly, pre-post comparison test with PRES showed that the music therapy with song was effective on improvement the receptive and expressive language ability of 4 children.
The purpose of this study was to examine the effect that preferred music listening had on police officers' occupational stress and fatigue. The musical intervention took place over a total of six sessions from October 11 to October 19, 2016. At each session, the experimental group (n = 19) received 20 minutes of music listening with individually customized playlists that were compiled based on their preferred music list. The control group (n = 21) simply took a break from work for 20 minutes. Every participant checked his or her occupational stress and fatigue level before and after the experiment using the Occupational Stress Inventory and Subjective Symptoms of Fatigue Test. The data were then analyzed by the SPSS 22.0 statistics program. To examine the homogeneity and pretest-posttest results between groups, an independent t test was conducted, and a paired t test was used to examine the pretest-posttest results within groups. The results confirmed all hypotheses. Findings support that the use of preferred music listening is an effective way to help police officers to control their occupational stress and fatigue. This study used a convenience sample and has limited generalizability. Future research should explore interactive approaches in music therapy as well as receptive music listening for alleviating police officers' occupational stress and fatigue.
Positive attitude toward mathematics is gaining bigger recognition as an important contributing factor to mathematical ability. As a strategy for strengthening affective domain and betterment of mathematics teaching and loaming, classifying students by their causes for liking or disliking mathematics can be an effective way In this study the author tried to devise methods to classify students by their types of math disliking and investigate correlations between mathematical achievements and these math-disliking types from a sample group of 8th graders. To identify the types of reasons why 8th graders dislike mathematics, a questionnaire with 30 items was made firstly. Then by applying the 'Factor analysis' of SPSS, the 30 items were divided into five partitions. Through abstraction of each partition, five math-disliking types, 'Competences', 'Basics', 'Confidences', 'Usefulness', and 'Teachers' were defined. They are expected to help teachers for describing each student's tendency of math-disliking. Further, correlation coefficients between mathematical achievements and each of the five math-disliking type were investigated against 4 groups which were made from sample group by the discrimination of gender and two levels (high and low) of mathematical achievements in cognitive area. As results, the following facts were found. (i) The trends of correlations between cognitive achievement and the five math disliking types were different across the 4 groups at statistically meaningful degrees. (ii) Most of the male students who had math-disliking types were proved to be in the low achievement level. But for the female students, only 50% of students who had math-disliking types were in the low achievement level. (iii) Compared to male students, higher portion of female students had math-disliking types despite their high achievement in cognitive area.
During early pregnancy, before the development of a functioning thyroid gland, thyroid stimulating hormone (TSH) is a very sensitive marker of thyroid dysfunction during pregnancy. Normal values have been modified during gestation with a downward shift. The fetus is influenced by the TSH supplied by the mother. TSH and free thyroxine (FT4) concentrations vary during pregnancy and conventional units can vary between laboratories. A downward shift of the TSH reference range occurs during pregnancy, with a decrease in both the lower and upper limits of maternal TSH, relative to the typical non-pregnant TSH reference range. Each laboratory produces its own reference TSH and FT4 concentrations because there are many different assays that yield different results in pregnancy. Therefore, automated immunoassays used for serum FT4 analysis are still used widely, but the important considerations discussed above must be noted. The use of population-based, trimester-specific reference ranges remains the best way to handle this issue The slight downward shift in the upper reference range of TSH occurring in the latter first trimester (7~12 weeks) of pregnancy, typically not observed prior to 7 weeks. Their use indicates high or low levels in a quantitative manner independent of the reference ranges. These data highlight the importance of calculating population-based pregnancy-specific thyroid parameter reference intervals. A precision medicine initiative in this area will require the collection and analysis of a large number of genetic, biological, psychosocial, and environmental variables in large cohorts of individuals. Large prospective randomized controlled trials will be needed to resolve these controversies.
Objectives: REM sleep behavior disorder (RBD) has received little attention in epidemiologic studies. This study aimed to determine the prevalence of probable REM sleep behavior disorder (pRBD) in the elderly population and its clinical features. Methods: A random sample of 1,588 was selected from a roster of 14,050 elderly population living in Osan city. The subjects were asked to fill out the REM sleep behavior disorder screening questionnaire (RBDSQ). Subjects whose score were 5 or higher on RBDSQ underwent a diagnostic phase of person-to-person assessment by experts in RBD. Results: Among 1,588 subjects, 886 elderly subjects participated in the screening phase and 123 subjects were assessed in the diagnostic phase. Eleven subjects were diagnosed as having pRBD, so prevalence was 1.5% (95% CI=0.70-2.30%). The frequency of depression and cognitive decline was significantly increased in patients with pRBD compared to subjects without pRBD, and there was no difference in sleep disturbances between two groups. Conclusions: Probable REM sleep behavior disorder is not rare in the elderly but frequently under-recognized. More attention should be paid to evaluation and treatment of RBD.
The purpose of this study was to examine the effect of GI-STEAM program on leadership, creative personality, and learning flow of elementary Gifted Students. GI-STEAM program was the convergence model of Group Investigation that belongs to Co-learning and STEAM framework of learning criterion. The participants were 16 gifted students in a Korean elementary school located in Gyeong-gi province. The experimental design was one group pretest-posttest design. After a pretest on leadership, creative personality, and learning flow was conducted, classes were carried out as GI-STEAM program for the gifted student and a post-test was conducted. The study results of the class that was conducted twelve times for two weeks are as follows. First, Individual area of leadership is meaningfully developed in statistics after GI-STEAM program. The sub-domains of leadership, such as the communication, organization management, society commitment and teamwork showed a statistically significant improvement. Second, the domain of creative personality didn't show meaningful difference after GI-STEAM program. However, the aesthetic in the sub-domains of the creative personality showed a statistically significant improvement. Third, learning flow was meaningfully developed in statistics after GI-STEAM program. The sub-domains of the leadership, such as the balance between challenge and ability, integration with behavior and consciousness, concrete feedback and Autotelic experience showed a statistically significant improvement. In conclusion, GI-STEAM is an effective program for improving ability of communication, aesthetic sensibility, which are core competency of 'creative-convergence' gifted students. For this reason, it is highly considered that various programs applying GI-STEAM should be developed.
