This study aimed to compare the effects of sit-to-stand training, or training to stand up from sitting positions at various seat heights, on the balance recovery among stroke patients. This study included 20 stroke patients who were randomly divided into two groups. Each group was trained for six weeks, three times a week from March to June 2019. Static balance and dynamic balance were measured, and the variations were analyzed using the paired t-test and the independent t-test. There were significant changes observed in both static and dynamic balance (p<.05) before and after training. However, no significant changes were seen in the static balance in the standing posture with eyes closed (p>.05). This study confirmed that there was a significant effect of training on the balance of stroke patients, especially when progressively lower seat heights were used during the training. This suggests new directions for treatment during rehabilitation for balance recovery of stroke patients. Further studies will need to apply this training to a larger number of subjects, and use various training methods such as randomization of seat height to enable the generalization of the results of this study and application in clinical practice.

In this paper, a case study of basic data science practice education for field teachers and pre-service teachers was studied. In this paper, for basic data science education, spreadsheet software was used as a data collection and analysis tool. After that, we trained on statistics for data processing, predictive hypothesis, and predictive model verification. In addition, an educational case for collecting and processing thousands of public big data and verifying the population prediction hypothesis and prediction model was proposed. A 34-hour, 17-week curriculum using a spreadsheet tool was presented with the contents of such basic education in data science. As a tool for data collection, processing, and analysis, unlike Python, spreadsheets do not have the burden of learning program- ming languages and data structures, and have the advantage of visually learning theories of processing and anal- ysis of qualitative and quantitative data. As a result of this educational case study, three predictive hypothesis test cases were presented and analyzed. First, quantitative public data were collected to verify the hypothesis of predicting the difference in the mean value for each group of the population. Second, by collecting qualitative public data, the hypothesis of predicting the association within the qualitative data of the population was verified. Third, by collecting quantitative public data, the regression prediction model was verified according to the hypothesis of correlation prediction within the quantitative data of the population. And through the satisfaction analysis of pre-service and field teachers, the effectiveness of this education case in data science education was analyzed.

Background: To analyze the effect of self-regulation on the fear of dental treatment in order to use it as basic data for efficient oral health care among male adolescents. Methods: A survey was administered to 241 first graders of specialized high schools in Daegu using a self-entry method. Twenty questions about fear of dental treatment and fifteen questions about self-regulation were included. The higher the score, the higher the fear of dental treatment and the self-regulation ability, showing a high reliability of 0.972 and 0.750, respectively. Results: The mean score of the participants' self-regulation ability was 3.25±0.51 and that of the degree of fear for dental treatment was relatively low at 1.72±0.85. It was confirmed that the higher the academic performance (F=7.635, p<0.01), the better was the self-regulation based on self-diagnosis (F=3.142, p<0.05), and was associated with higher health awareness (F=5.894, p<0.01). The degree of fear for dental treatment was significantly higher in the self-diagnosis-induced poor health group (F=4.933, p<0.01) and associated with a lower awareness of health (F=3.093, p<0.05). The participants' self-regulation ability was significantly negatively correlated with the degree of fear regarding dental treatment (r=-0.269, p<0.01). Regression analysis was performed using the degree of fear as a dependent variable and including sub-area variables of self-diagnosis-based health status, perception of health, and self-regulation ability as independent variables (β=-0.163, p<0.05). Among the self-regulation abilities, controlled composition (β=-0.232, p<0.01) had a significant effect; the higher the composition, the lower the degree of fear. The total explanatory power of this variable was 8.5%. Conclusion: An appropriate customized education program that can encourage individuals to practice self-care and maintain oral hygiene along with a clear understanding of underlying individual oral health conditions during adolescence is essential for promoting oral health.

Objective : The aim of this study was to determine the priority competency by analyzing the importance, performance, and educational requirements of occupational therapists to develop a competency in performing sensory integration intervention. Methods : Occupational therapists were surveyed by gender, age, educational background, work location, occupational therapy experience, and sensory integration therapy experience. The difference was investigated through the importance-performance analysis of competency, and the priority of the competency was investigated using the Borich demand analysis method. Results : The therapists recognized professional competency as the most important, whereas performance was the least important. In all sub-competencies, the importance was high, but the performance was low. As a result, the education requirement was highest for professional competency. The importance-performance analysis revealed that professional competency was the area requiring the most urgent improvement. As a result of the Borich demand analysis, statistically significant differences between the importance of all competencies and the actual performance. The most significant difference was found in the professional competency group. Conclusion : The occupational therapists in this study who performed sensory integration interventions recognized professional competency as the most important but most lacking in actual clinical practice. The results of this study will be used as guidelines for developing competency-based sensory integrated intervention curricula.

This study aims to examine the effect of housing characteristics of older adults on the willingness to continue living in local communities in order to realize the Aging in place of the elderly in Korea. Considering that the health status of the elderly is important for aging in place, both healthy and unhealthy cases were analyzed in the analyses. Housing characteristics include home ownership, housing cost burden, housing convenience, housing satisfaction, and residential environment satisfaction. The study sample is 9,798 elderly people from the 2017 survey on the elderly. Key findings are as follows: First, while 6,704 older adults (68.4%) chose to continue living in the community, 3,094 (31.6%) of the elderly did not choose to live in the local community. Second, the elderly who chose to stay in the local community are likely to have more real estate assets and less burden of housing expenses than the elderly group who did not. Third, the results report that older adults with more real estate assets and lower the housing cost burden are likely to choose sustainable living in the local community. The findings suggest that the majority of the elderly actually preferred Aging in place. This study concludes with practice and policy implications for realizing aging in place considering the elderly's needs.

PURPOSE. This study aimed to evaluate the effect of incorporating zirconium oxide nanoparticles (nano-ZrO₂) in polymethylmethacrylate (PMMA) denture base resin on flexural properties at different material thicknesses. MATERIALS AND METHODS. Heat polymerized acrylic resin specimens (N = 120) were fabricated and divided into 4 groups according to denture base thickness (2.5 mm, 2.0 mm, 1.5 mm, 1.0 mm). Each group was subdivided into 3 subgroups (n = 10) according to nano-ZrO₂ concentration (0%, 2.5%, and 5%). Flexural strength and elastic modulus were evaluated using a three-point bending test. One-way ANOVA, Tukey's post hoc, and two-way ANOVA were used for data analysis (α = .05). Scanning electron microscopy (SEM) was used for fracture surface analysis and nanoparticles distributions. RESULTS. Groups with 0% nano-ZrO₂ showed no significant difference in the flexural strength as thickness decreased (P = .153). The addition of nano-zirconia significantly increased the flexural strength (P < .001). The highest value was with 5% nano-ZrO₂ and 2 mm-thickness (125.4 ± 18.3 MPa), followed by 5% nano-ZrO₂ and 1.5 mm-thickness (110.3 ± 8.5 MPa). Moreover, the effect of various concentration levels on elastic modulus was statistically significant for 2 mm thickness (P = .001), but the combined effect of thickness and concentration on elastic modulus was insignificant (P = .10). CONCLUSION. Reinforcement of denture base material with nano-ZrO₂ significantly increased flexural strength and modulus of elasticity. Reducing material thickness did not decrease flexural strength when nano-ZrO₂ was incorporated. In clinical practice, when low thickness of denture base material is indicated, PMMA/nano-ZrO₂ could be used with minimum acceptable thickness of 1.5 mm.

BACKGROUD/OBJECTIVES: Allomyrina dichotoma larva (ADL), one of the many edible insects recognized as future food resources, has a range of pharmacological activities. In a previous study, an ADL extract (ADLE) reduced the hepatic insulin resistance of high-fat diet (HFD)-induced diabetic mice. On the other hand, the associated molecular mechanisms underlying pancreatic beta-cell dysfunction remain unclear. This study examined the effects of ADLE on palmitate-induced lipotoxicity in a beta cell line of a rat origin, INS-1 cells. MATERIALS/METHODS: ADLE was administered to high-fat diet treated mice. The expression of apoptosis-related molecules was measured by Western blotting, and reactive oxidative stress generation and nitric oxide production were measured by DCH-DA fluorescence and a Griess assay, respectively. RESULTS: The administration of ADLE to HFD-induced diabetic mice reduced the hyperplasia, 4-hydroxynonenal levels, and the number of apoptotic cells while improving the insulin levels compared to the HFD group. Treatment of INS-1 cells with palmitate reduced insulin secretion, which was attenuated by the ADLE treatment. Furthermore, the ADLE treatment prevented palmitate-induced cell death in INS-1 cells and isolated islets by reducing the apoptotic signaling molecules, including cleaved caspase-3 and PARP, and the Bax/Bcl2 ratio. ADLE also reduced the levels of reactive oxygen species generation, lipid accumulation, and nitrite production in palmitate-treated INS-1 cells while increasing the ATP levels. This effect corresponded to the decreased expression of inducible nitric oxide synthase (iNOS) mRNA and protein. CONCLUSIONS: ADLE helps prevent lipotoxic beta-cell death in INS-1 cells and HFD-diabetic mice, suggesting that ADLE can be used to prevent or treat beta-cell damage in glucose intolerance during the development of diabetes.

The goal of this study is to investigate the current status of implementation of convergence education in elementary, middle, and high schools. A survey was conducted on 871 in-service teachers nationwide, and frequency analysis was conducted by school level. Key findings are as follows: first, 449 (51.5%) are found to practice convergence education. Second, the reason for implementing convergence education is the voluntary effort of teachers and the educational necessity for the future society. Third, it was found that convergence education is being implemented centered on science, arts, and social studies as a link between subjects in regular curriculum hours. Fourth, 270 (64%) of teachers who implemented convergence education in response to COVID-19 performed online convergence education, and experienced difficulties in creating class materials and communicating with students. Fifth, the excessive work of teachers, insufficient support for teacher training and research group activities, and lack of various convergence education programs are suggested as reasons for not implementing convergence education. This study hopes to provide implications for policy and implementation for revitalizing convergence education.
