In this study, a meta-analysis was conducted to find out the effects of convergent "untact" exercise programs on the balance, gait, and falls efficacy of Parkinson's patients. In this study, the PICO were Parkinson's disease, virtual reality program and an e-exercise program intervention, a comparative intervention with the contact interventions applied, and without any interventions applied, outcomes were balance, gait, and fall efficacy. The survey period was between January and February 2021, and five papers were selected and subjected to meta-analysis. Risk of bias, a tool commonly used for randomized control trial studies, was used. Furthermore, RevMan program was used to investigate effect size of untact exercise programs. The result of the meta-analysis showed that the effect size of balance of the untact exercise program group was 1.27 (SMD=1.27; 95% CI 0.72 to 1.83) (Z=4.51, p<0.001), the effect size of fall efficacy was 0.52 (SMD=0.52; 95% CI -0.000 to 1.03) (Z=1.96, p=0.05), and the effect size of gait was -0.40 (SMD=-0.40; 95% CI -1.00 to 0.10)(Z=1.32, p>0.05). A total of 5 literature analysis showed that untact exercise program is more effective in improving balance and falls efficacy than contact exercise program, but no difference in effectiveness was shown on gait.

In the era of 'Untact', virtual reality-based job training platforms are actively being used as part of non-face-to-face education for students with developmental disabilities. Because the people with developmental disabilities may lack sufficient cognitive abilities, it is difficult to conduct untact training seamlessly without the help of a third party. Therefore, it is necessary for training programs to identify the right timing to provide help so that the training can be continued. This research analyzed the visual attention of students with developmental disabilities in virtual reality-based job training program in order to determine the point of time when an intervention is required by the trainee. Results showed that students who completed the mission tended to have intense visual attention on a small number of objects for a certain period of time; the visual attention of the students who failed tended to shift erratically among multiple objects.

Many domestic construction companies are continuously trying to utilize weather information for construction management. The effect of the weather is greatly reflected in the construction industry because there are many outdoor work. Therefore, weather information is clearly needed to predict the exact construction period. And the calculation of the number of non-working days considering the weather information is very important. However, many construction companies have difficulty calculating the exact construction period because it is difficult to predict the exact long-term weather. In this study, it is analyzed the past long-term weather information. Then the weather information by region and season is applied to the construction management system. Finally, it is confirmed the workable date, the field information and the weather information.

Purpose: This study aimed to investigate whether distribution and service companies maintained their accounting information quality and provided reliable information despite the economic changes occurring after the outbreak of the COVID-19 pandemic in Korea. The distribution industry has enjoyed increased demand as many companies expanded their untact distribution channels, including to online sales. However, as the pandemic drags on, their future prospects remain uncertain. Research design, data, and methodology: In this study, we define 2018-2019 as the "pre COVID-19 period" and 2020 as the "post COVID-19 period." An empirical analysis was performed using a regression model that includes POST, the independent variable, indicating the post COVID-19 period, and discretionary accruals(DA), a proxy for earnings management, as a dependent variable. Results: The analysis shows that the coefficient of POST is significantly positive (+) for the dependent variable DA. This finding suggests that distribution and service companies engaged in more earnings management during the post COVID-19 period than during the pre COVID-19 period, indicating their awareness of the uncertainty of future business performance as the pandemic persists. An additional analysis confirmed that smaller companies with fewer stakeholders and higher information asymmetry tend to engage more in earnings management than larger companies.
