8주간 주 2회, 1회 30분 16명의 남자 대학생을 대면 운동 그룹 8명, 실시간 비대면 운동 그룹 8명으로 나누어 운동을 실시하였다. 종속변인으로는 신체조성과 체력을 홈트레이닝 실시 전과 후 총 2번 측정하였다. 자료처리는 운동 방법의 차이와 측정 시기에 따른 신체조성과 체력에 미치는 영향을 알아보기 위해 반복측정 이원배치분산분석(two-way ANOVA with repeated measure)을 실시하였고, 사후분석으로 Bonferoni를 실시하였다. 그룹 간 변화량의 평균 차이를 비교하기 위해 사전-사후 차이의 변화량을 산출한 후 독립표본 t-검정(Independent t-test)을 실시하였다. 모든 통계적 유의수준은 p<.05로 설정했다. 8주간의 홈트레이닝은 대면 운동과 실시간 비대면 운동 방법에 상관없이 남자 대학생의 골격근을 증가시키고 근력, 근지구력, 심폐지구력을 증가시켰다. 또한, 대면·실시간 비대면 운동 방법간의 효과 차이는 나타나지 않았다. 따라서 실시간 비대면은 대면 운동과 마찬가지로 남자 대학생들의 골격근과 체력을 향상시키기에 효과적인 운동 방법이 될 수 있음을 시사한다. 또한, 이동이 불편한 환자들이나 노인들에게 적용될 수 있는 실시간 비대면 운동 프로그램이 검증된다면 대면 운동을 실시하기 어려운 대상에게도 효과적인 방법이 될 수 있을 것으로 사료된다.

Objective: This study is to investigate the effect of real-time feedback from the therapist on posture, muscle strength, pain of subjects with forward head posture based on a non-face-to-face complex exercise program. Design: Two-group pretest-posttest design. Methods: Thirty healthy men and women in their twenties with forward head posture with a Craniovertebral angle of 52° or less were targeted, the final selection was made as 15 experimental groups who performed the non-face-to-face intervention program while receiving real-time feedback and 15 control subjects who performed the non-face-to-face intervention program without providing feedback. Six of them were eliminated, and a total of 24 were conducted as subjects. All exercise groups performed an exercise program three times a week, 30 minutes each, for a total of two weeks. Before and after exercise, Craniovertebral angle (CVA), CranioRotation angle (CRA), muscle strength, and tenderness threshold were evaluated. Results: Significant differences were shown in both groups in CVA, and tenderness threshold before and after exercise (p<0.05), and CRA, the left middle trapezius muscle strength, only in the experimental group (p<0.05). In the comparison of theamount of change between exercise groups, the group that received feedback on CVA, CRA and tenderness threshold showed a significant change than the group without feedback (p<0.05). Conclusions: As a result of this study, it can be seen that the therapist's real-time feedback is more effective in improving the forward head posture. This requires feedback from the therapist on posture correction during non-face-to-face exercise intervention.

Purpose: Since coronavirus disease 2019 (COVID-19) spread around the world, non-face-to-face services have emerged as the new normal. The functioning of children with developmental disabilities and cerebral palsy improves when parents, therapists, and institutions cooperate. We aimed to investigate the difficult environment of pediatric physical therapy caused by COVID-19, and grasp parents' perceptions of home exercise programs. We intend to design home exercise programs for pediatric treatment in the future and create a non-face-to-face pediatric rehabilitation service system based on our findings. Methods: The first survey was conducted on 30 parents who had children with cerebral palsy and developmental disabilities. It was produced after consultation with relevant experts and discussion with the research team, based on a survey conducted in a previous study. The second survey was produced by revising and supplementing the opinions of parents who completed the first survey and consulting experts. Thereafter, an online survey was conducted on 118 parents who had children with cerebral palsy and developmental disabilities. Results: 61.01 % of the parents reported that they were anxious or afraid for their children to be treated for infectious diseases. 83.90 % of the parents reported that the role of parents had increased. 50.00 % of the parents complained of a lack of skill. 85.59 % of the parents reported that they needed a home exercise program provided by the organization. As a non-face-to-face exercise management method, 35.59 % of the parents wanted a real-time video recording electronically mailed to them, and 34.75 % wanted real-time education using video conferencing programs such as zoom. Conclusion: The threat of COVID-19 has further emphasized the importance of social cooperation and management, leading organizations to enter a new era of non-face-to-face rehabilitation services. It is necessary to collect and systematize related studies to reflect more diverse opinions and improve the perceptions of therapists and parents.

Purpose : This study was conducted to compare two non-face-to-face exercise interventions depending on whether mobile applications and wearable exercise aids are used to find out which interventions are more effective in improving senile sarcopenia. Ultimately, it was conducted to provide basic data for developing non-face-to-face intervention methods to improve sarcopenia. Method : In this study, 18 elderly sarcopenia and possible sarcopenia aged 65 or older were randomly assigned to the digital and self-exercise intervention groups. The digital exercise intervention group performed eight exercise programs with mobile applications and wearable exercise aids to record and manage the elderly performing the programs in real time. And the self-exercise intervention group performed the same program on its own as implemented in the digital exercise group. The intervention was applied for 8 weeks, and before and after the intervention, sarcopenia evaluation and physical function evaluation were performed. Results : In the digital exercise intervention group, arm muscle mass, skeletal muscle index, SPPB, 5TSTS, and BBS were improved, and in the self-exercise intervention group, grip strength, SPPB, 5TSTS, and BBS were improved. Conclusion : It was confirmed that both groups are effective in improving physical performance and physical function, the digital exercise intervention is effective in improving muscle mass and self-exercise intervention is effective in improving muscle strength. Therefore, this study proposes to apply intervention methods separately according to the indicators to improve and prevent sarcopenia, and also simplify the instructions of applications used to improve sarcopenia and to create an environment where users can be trained regularly on how to use it. And, In the future, studies for the development of devices to be designed to help non-face-to-face exercise interventions or studies on the differences between face-to-face and non-face-to-face exercise interventions should be conducted in terms of the effect of improving sarcopenia.

This research is a case study about "Critical Thinking and Debate Education" class which was done for freshmen at the engineering college of "S" Women's University. Real time remote classes through LMS and ZOOM were the most effective tools under on-line circumstances, considering the fact that video lectures only cannot cultivate students' capabilities of critical thinking and communication. Throughout the analysis on students' self-reflection journals and lecture evaluations, this paper examined considerable future points and the pros and cons of "Critical Thinking and Debate Education" under online presentation and discussion situation. As research outputs, students told they could feel less nervousness and anxiety when they exercise and have a presentation because they could choose familiar space for them. In addition, students also told that they feel comfortable about both self-feedback and peer evaluation, repeatedly seeing the recorded video clip. However, on the contrary, sometimes students felt uncomfortable due to unstable internet connection through the online classes, and they also were regretful about the missing chances of interaction between a teacher and students and of intimate exchanges among students. They also told they had felt a kind of limit of enhancing their presentation skills just in front of the monitor. Considering these outcomes, this research paper points out that online education needs to be proceeded by strengthening multi layered feedback to students with the build-up of a non-face-to-face stable educational infrastructure, application of online instructional strategy, and utilization of YouTube platform and video contents. Through this research paper, I hope the new system of encompassing on/off line "Critical Thinking and Debate Education" and effective teaching and learning method can be developed soon by strengthening the strength of online education.

As the elderly population increases, the number of patients with various joint diseases, including degenerative arthritis, is steadily increasing. CPM medical devices are needed to effectively treat degenerative arthritis that is common in the elderly population. Domestic CPM medical devices have limited functions and are highly dependent on imports for expensive imported medical devices. To solve this problem, we designed a ROM measurement function using a current sensor that is not present in existing composite joint CPM medical devices. The algorithm was designed using the fact that the force caused by joint stiffness greatly increases the current flowing through the DC motor. In addition, the need for digital healthcare in the medical field is gradually expanding as the proportion of chronically ill patients increases due to the spread of the non-face-to-face economy due to COVID-19 and the aging population. Therefore, this paper aims to improve the performance of CPM medical devices by allowing real-time confirmation of rehabilitation exercise information and operation range measurement results in accordance with digital healthcare trends through a Bluetooth application developed as an Android studio.

This study evaluated the effectiveness of an obesity program developed to solve 'obesity', which was selected as the top priority for urgent improvement among the dietary problems of elementary school students in Busan. The program aimed to practice four health rules every day (sleep early, eat two vegetables with each meal, reduce sugary snacks, and exercise for 30 minutes every day). The participants were trained to practice the four rules online in real time every day for three weeks, and their performance in nutrition education tasks was monitored using Padlet. The anthropometric measurements showed no change in the overall average weight before and after participating in the program, but all students grew in height (z=-6.978, P<0.001), and the number of obese students decreased significantly (z=-3.317, P<0.001). This obesity program was effective in improving height growth and obesity in elementary school students. In terms of dietary changes, after participating in the program, the frequency of vegetable consumption increased significantly (z=-4.849, P<0.001), the frequency of sweet snack consumption decreased significantly (z=-4.298, P<0.001), and the bedtime improved (z=-1.000). Therefore, the non-face-to-face, self-directed obesity program developed in this study is expected to reduce the workload of nutrition teachers carrying a heavy workload such as meal service and nutrition classes, and can be used as an efficient nutrition counseling program.
