Screen Golf provides a more realistic interface to users by implementing sophisticated sensors and 3D graphics so that they can play golf in an environment almost identical to the actual golf course, to provide a sense of reality that goes beyond simply enjoying golf indoors. In addition, users who experienced this interface environment showed a tendency to feel the fun of golf more and become more immersed in golf. Therefore, it is most important to provide an effective realistic interface in screen golf. In this study, the meaning of screen golf as a tangible sport and various interface elements embodied in screen golf were summarized. Also the factors that enable users to feel reality and fun of actual golf to make users more immersed in screen golf were identified. For this, interface elements based on sensory elements were arranged in terms of visual, auditory, and tactile sense, and improvement plans and directions for providing effective sensory interfaces for screen golf were suggested through user FGI, targeting regular customers of Golfzone and KakaoVX screen golf, and in-depth interviews with experts. As a result of the analysis, it was confirmed that the course information including the yardage and the play situation-directed graphic are elements that make immersion in the visual aspect. In terms of tactile aspect, the fact that users actually use golf equipment, as well as the sense of existence of a physical interface that embodies various course environments and course setting appeared to be an important factor. In particular, in the auditory aspect, it was confirmed that providing customized services for each user through AI caddy implemented to resemble a actual caddy is the most effective way to immerse users in screen golf with greater fun and realism.

Since the outbreak of Corona 19, Universities and Lifelong Education Center's arts and sports classes are mainly conducted online. Unfortunately, even in dance where practical practice through face-to-face classes is important, the satisfaction of students is falling because of the limitations of online education. Therefore, it is necessary to measure the quality of education service they feel. In addition, since their academic departure is increasing, we intend to comprehensively study user satisfaction, continuous use intention, and academic continuity intention related to online education. This study confirmed the causal relationship between these 4 variables through exploratory factor analysis, reliability analysis, model fit and validity verification, and path analysis. As a result of the study, 3 out of 6 hypotheses were adopted, and the of education service quality had a positive effect on satisfaction and use in online dance education. But there was also a limit that did not affect the intention to continue the study. In order to solve fundamental problems such as academic departure, follow-up studies taking into account more diverse social variables are needed.

The purpose of this study was to determine the effects of asthma, allergic rhinitis, atopic dermatitis, and high intensity exercise on depressive symptoms and suicidal ideation in adolescents. This is a secondary data analysis study using 15th Korean Children and Youth Panel Survey. Data analysis was performed by chi-square and logistic regression analysis using SPSS 22.0. As a result, there were differences in allergic diseases, high-intensity exercise, smoking experience, and drinking experience in both depressive symptoms and suicidal ideation. After adjusting for smoking experience and alcohol experience, asthma, allergic rhinitis, and atopic dermatitis were influencing factor for depression symptoms(OR:1.16, 95% CI:1.07-1.26; OR:1.16, 95% CI:1.11-1.21; OR:1.17, 95% CI:1.11-1.23) and for suicidal ideation(OR:1.32, 95% CI:1.20-1.47; OR:1.22, 95% CI:1.15-1.29; OR:1.21, 95% CI:1.14-1.29). However, high intensity exercise had decreased depressive symptoms and suicidal ideation(OR:0.90, 95% CI:0.86-0.94; OR:0.85, 95% CI:0.80-0.90). As a result of this study, it was found that allergic diseases and high-intensity exercise had a great effect on mental health in adolescents, and we may use it as basic data for prevention and research related to the mental health of adolescent.

Rapid changes in modern society after the COVID-19 have highlighted artificial intelligence talent as a major influencing factor in determining national competitiveness. Accordingly, the Ministry of Education planned a large-scale SW·AI camp education project to develop the digital capabilities of 4th to 6th grade elementary school students and middle and high school students who are in a vacuum in artificial intelligence education. Therefore, this study aims to develop a camp-type SW·AI education program for students in grades 4-6 of elementary school so that students in grades 4-6 of elementary school can acquire basic knowledge in artificial intelligence. For this, the meaning of SW·AI education in elementary school is defined and SW·AI contents to be dealt with in elementary school are: understanding of SW AI, 'principle and application of SW AI', and 'social impact of SW AI' was set. In addition, an attempt was made to link the set elements of elementary school SW AI education and learning with related subjects and units of textbooks currently used in elementary schools. As for the program used for education, entry, a software coding learning tool based on block coding, is designed to strengthen software programming basic competency, and all programs are designed to be operated centered on experience and experience-oriented participants in consideration of the developmental characteristics of elementary school students. In order for SW·AI education to be organized and operated as a member of the regular curriculum, it is suggested that research based on the analysis of regular curriculum contents and in-depth analysis of SW·AI education contents is necessary.

This study was to determine differences and relations in nursing students' clinical practice stress and clinical competence by gender role identity. The study made a questionnaire survey of 450 nursing students of 2 colleges in J city, Gyeongnam, from June 1st to 30th, 2020. Data from 417 sheets were finally analyzed with descriptive statistics, χ2test, t-test, ANOVA, Scheffe test, correlation and hierarchial regression analysis. The analysis found that most of the participants belonged to undifferentiated type(34.3%) in gender role identity. Clinical competence showed significantly different(F=20.98, p<.001), but clinical practice stress showed no significant difference depending on that identity(F=1.56, p=.199). Clinical competence had positive correlations with the index of masculinity(r=.397, p<.001) or the index of feminity(r=.325, p<.001), but had no with clinical practice stress(r=.061, p=.217). Gender role identity turned out to be a factor that would significantly influence clinical competence(F=6.67, p<.001). These findings suggest that gender role identity of nursing students should be confirmed prior to clinical practice education and, thereon, interventions for clinical competence improvement should be developed.

Purpose: Reflux esophagitis is a disease caused by the reflux of stomach contents and stomach acid etc. into the esophagus due to defect in the lower esophageal sphincter and is currently increasing worldwide. This study was conducted to evaluate the effect of a mixture of Citrus Reticulata and Scutellariae Radix (CS) extract on acute reflux esophagitis in rats. Methods: Rats were divided into five groups for examination: normal group (Normal, n = 8), water-treated acute reflux esophagitis rats (Control, n = 8), tocopherol 30 mg/kg body weight-treated acute reflux esophagitis rats (Toco, n = 8), CS 100 mg/kg body weight-treated acute reflux esophagitis rats (CS100, n = 8), CS 200 mg/kg body weight-treated acute reflux esophagitis rats (CS200, n = 8). The experimental groups were administrated of each treatment compounds and after 90 min, acute reflux esophagitis was induced through surgery. Rats were sacrificed 5 h after surgery. We measured the level of reactive oxygen species (ROS) in serum and analyzed the expression of nicotinamide adenine dinucleotide phosphate, inflammatory, and tight junction-related proteins by western blot in the esophageal tissues. Results: CS administration significantly protected the esophageal mucosal damage due to reflux esophagitis, and the level of ROS in the serum was significantly reduced with CS administration as compared to Control. In addition, CS administration significantly suppressed mitogen-activated protein kinase (MAPK or MAP kinase) and nuclear factor-kappa B (NF-κB) pathways and increased protein expressions of tight junction protein. Conclusion: These results suggest that the CS not only regulates the expression of inflammatory proteins by inhibiting oxidative stress, but also reduces damage to the esophageal mucosa by inhibiting the expression of tight junction proteins.
