  • Misconceptions are one of the most important and long-lasting studied themes on science education. It is because their nature is obstinate and settled as well as they corrupt students' understanding of science concepts. This study examines whether preservice elementary school teachers enrolled in biology teaching material research course changed positively on science teaching efficacy and correcting life science misconceptions when they used the handbook developed for this study. The handbook comprises 203 life science concepts surveyed among preservice teachers holding from advanced researches and arranged by 2007 Revised Science Curriculum. 107 preservice elementary school teachers participated in the study. Forty-six (46) of them were assigned to the experimental group and the other 61 to the control group. ANOVA was conducted for analyzing data. Science Teaching Efficacy Belief Instrument (STEBI) and the life science misconception test which was developed for this study, were administrated as assessing instruments for pretest and posttest. The experimental group, using the handbook, acquired higher scores in both tests on statistical significance level than the control group who were not using the handbook. The results indicate the handbook developed for correcting life science misconceptions for this study is effective in enhancing science teaching efficacy and correcting life science misconceptions.

  • The purpose of the present study was to determine the effect of 4 weeks course of motorized spinal decompression delivered via SpineMT(mobilization & traction) combined with therapeutic modalities on the treatment of patients with lumbar radiculopathy(LRP). A total of 15 patients with LRP (mean age, 36.63 years; age range 20-50years) participated in this study. 4 weeks course of spinal decompression delivered via SpineMT combined with therapeutic modalities was delivered to the patients for 6 days per week for the first two weeks, and four times per week for two additional weeks. The entire treatment consisted of 20 visits over 4 week period. Comparisons of changes in the muscle strengthening (MS), straight leg raise (SLR), and Oswestry disability index (ODI) at pre-intervention, after 10 treatment sessions, and at discharge (after 20 treatment sessions) were analyzed. There were significant improvements in the outcome measures of MS test, SLR test, and ODI score after 10 and 20 sessions of spinal decompression treatment combined with therapeutic modalities as compared with the pre-intervention(p<0.05). Spinal decompression treatment combined with therapeutic modalities appears to be a safe and efficacious, noninvasive treatment modality for patients with LRP.

  • Background: This study aims to examine changes in fraudulent claim counts and total reimbursements before and after enhancements in counterfeit claim controls and monitoring of provider claim patterns under the "Proactive self-audit pilot program of fraudulent claims." Methods: This study used the claims data and hospital information (July 2021-February 2022) of the Health Insurance Review and Assessment Service. The data was collected from 1,129 hospitals assigned to the pilot program, selected from the providers who filed a claim for reimbursement for intravenous injections. Paired and independent t-tests, along with regression analysis, were utilized to analyze changing patterns and factors influencing claim behaviors. Results: This program led to a reduction in the number of fraudulent claims and the total amount of reimbursements across all levels of hospitals in the experimental groups (except for physicians below 40 years old). In the control group, general hospitals and hospitals demonstrated some significant decreases based on the duration since opening, while clinics showed significant reductions in specified subjects. Additionally, a notable increase was observed among male physicians over the age of 50 years. Overall, claims and reimbursements significantly declined after the intervention. Furthermore, a positive correlation was found between hospital opening duration and claim numbers, suggesting longer-established hospitals were more likely to file claims. Conclusion: The results indicate that the pilot program successfully encouraged providers to autonomously minimize fraudulent claims. Therefore, it is advised to extend further support, including promotional activities, training, seminars, and continuous monitoring, to nonparticipating hospitals to facilitate independent improvements in their claim practices.

  • The aim of this study was to enhancing the panoramic radiograph's clinical use for assessing mandibular measurements and formulating a function of those measurements from panoramic radiographs and lateral cephalograms in children. The panoramic radiographs and lateral cephalograms of 99 former orthodontic patients with skeletal class III malocclusion were selected. In each radiograph, gonial angles, ramus heights, and distance between lower incisors and symphysis were measured. The values of the studied parameters were compared by paired t-test, Pearson's correlation test and regression analysis. The mean value of the gonial angle in panoramic radiographs was $125.49^{\circ}$, and the value in lateral cephalograms was $127.50^{\circ}$. The Pearson's correlation coefficient (${\rho}$) between mean values of gonial angle in each radiograph was 0.945 (p < 0.001). The relationship between the gonial angle measurements obtained from each radiographs was represented as 'Gonial angle (Lateral cephalograms) = 0.920 ${\times}$ Average gonial angle (Panoramic radiographs) + 12.072' in the linear function. The coefficients of ramus heights, and distance between lower incisors and symphysis portrayed weaker correlations than gonial angles. A panoramic radiograph could be used to determine the gonial angle as accurately as a lateral cephalogram, and each gonial angle showed a strong positive relation. A panoramic radiograph is a useful tool for examining vertical growth pattern of patients, as well as a lateral cephalogram.

To this end, the effectiveness study was conducted based on the researchers' prior study of 'Development of Music learning program Using Applications Based on Design Thinking'. Under the study, two first graders who are attending P Middle School in Gyeonggi Province were selected as experimental(29) and control groups(29). The experimental group conducted the class using this program and the control group conducted a general music class. The pre-post-examination was conducted to find out the effects of this class on students' creativity, empathy, teamwork, and problem-solving skills. The course of the study was developed for seven weeks, a program pre-post-survey, and a response sample t-test was used to analyze the results. The study found that experimental groups show significant differences in creativity, empathy, cooperative spirit and problem-solving skills, while control groups that conducted general music classes had similar results in advance-postmortem. The group's students found that their ability to empathize with others in the problem situation was enhanced, their sense of rapid problem solving and achievement was high, and their ability to create creative ideas and enhance creativity in the process of solving the problem was improved. In the future, we look forward to using this music class activity in the field where new, creative, and diverse classroom models are needed.

  • Objective : The purpose of this study is to consider the change of hand function according to the quality of sleep and to find out a correlation among the quality of sleep and hand function, and sleep disturbing factors. Method : 23 patients who were hospitalized more than 6 months from Nov. 2017 to Jan. 2018 were tested for the quality of sleep used by sleep quality scale, for the grip strength used by a dynamometer, and for the coordination used by BBT and 9-Hole Peg test. The collected data were analyzed to implement the paired t-test and Pearson correlation coefficient. Result : In the high grade group of sleep score, the quality of sleep & BBT, and the grip strength & BBT have correlated each other; and in the medium group, only the latter has shown a correlation. In both groups, the quality of sleep and the sleep pattern have showed significant high correlation. Conclusion : When the elderly in geriatric hospitals show qualitative differences, BBT and the combination of treatment for the improvement of grip strength can improve the quality of sleep. And the sleep pattern intervention is considered to be effective to improve the quality of sleep.
