Purpose: This study examined the needs for asthma education programs as perceived by school-age children, parents, and teachers and investigated parents' and teachers' expectations for incorporating augmented reality (AR) in asthma education. Methods: This descriptive, cross-sectional study included 339 participants: 125 school-age children, 132 parents, and 82 teachers. Data were collected from children, parents, and teachers on the need for asthma education, the requirements for asthma education, and the expectations of parents and teachers for incorporating AR in asthma education. Data were analyzed using descriptive statistics, the t-test, analysis of variance, and the Scheffé test. Results: Asthmatic children and their peers, parents, and teachers all felt there was a significant need for education about asthma, with education on how to deal with an asthma attack being needed the most. The incorporation of AR programs in asthma education was viewed positively by both parents and teachers. Conclusion: An AR children's asthma education program should be developed in which children with asthma and their peers, parents, and teachers can participate together. Furthermore, it is expected that children with asthma will independently undertake more effective disease management after attending an AR asthma education program.

Purpose: This study examined the effects of plank exercise combined with breathing and arm exercises on the external oblique, internal oblique, and transverse abdominal muscle thickness. Methods: Thirty healthy adults consisting of 12 males and 18 females from K area were divided into a plank exercise combined with breathing and arm exercises group (n = 15) and a plank exercise only group (n=15). The changes in muscle thickness before the exercise and four and eight weeks after the exercise were analyzed using a two-way repeated analysis of variance (ANOVA). The significance level was set to ${\alpha}=0.05$. Post-hoc t-tests were conducted to detect the interactions between the time and groups, and the significance level was set to ${\alpha}=0.01$. Results: According to the experimental results, the external oblique abdominal muscle showed significant differences over time (p<0.05). The internal oblique abdominal muscle also showed significant differences over time and in the interactions between the time and groups (p<0.05). The transverse abdominal muscle showed significant differences over time, in the interactions between time and groups, and in the changes between the groups (p<0.05). Conclusion: The results indicated that plank exercise combined with breathing and arm movement exercises led to increases in the abdominal muscle thickness. These types of exercises may be useful in lumbar stabilization rehabilitation treatment.

Objective: This study aimed to evaluate the volume, amount, and localization of root resorption in the maxillary first premolars using micro-computed tomography (micro-CT) after expansion with four different rapid maxillary expansion (RME) appliances. Methods: In total, 20 patients who required RME and extraction of the maxillary first premolars were recruited for this study. The patients were divided into four groups according to the appliance used: mini-implant-supported hybrid RME appliance, hyrax RME appliance, acrylic-bonded RME appliance, and full-coverage RME appliance. The same activation protocol (one activation daily) was implemented in all groups. For each group, the left and right maxillary first premolars were scanned using micro-CT, and each root were divided into six regions. Resorption craters in the six regions were analyzed using special CTAn software for direct volumetric measurements. Data were statistically analyzed using Kruskal-Wallis one-way analysis of variance and Mann-Whitney U test with Bonferroni adjustment. Results: The hybrid expansion appliance resulted in the lowest volume of root resorption and the smallest number of craters (p < 0.001). In terms of overall root resorption, no significant difference was found among the other groups (p > 0.05). Resorption was greater on the buccal surface than on the lingual surface in all groups except the hybrid appliance group (p < 0.05). Conclusions: The findings of this study suggest that all expansion appliances cause root resorption, with resorption craters generally concentrated on the buccal surface. However, the mini-implant-supported hybrid RME appliance causes lesser root resorption than do other conventional appliances.

Quantitative high throughput screening (qHTS) assays are used to assess toxicity for many chemicals in a short period by collectively analyzing them at several concentrations. Data are routinely analyzed using nonlinear regression models; however, we propose a new method to analyze qHTS data using a nonlinear mixed effects model. qHTS data are generated by repeating the same experiment several times for each chemical; therefor, they can be viewed as if they are repeated measures data and hence analyzed using a nonlinear mixed effects model which accounts for both intra- and inter-individual variabilities. Furthermore, we apply a one-step approach incorporating robust estimation methods to estimate fixed effect parameters and the variance-covariance structure since outliers or influential observations are not uncommon in qHTS data. The toxicity of chemicals from a qHTS assay is classified based on the significance of a parameter related to the efficacy of the chemicals using the proposed method. We evaluate the performance of the proposed method in terms of power and false discovery rate using simulation studies comparing with one existing method. The proposed method is illustrated using a dataset obtained from the National Toxicology Program.
