본 연구는 융합적 비대면 방식의 운동 프로그램이 파킨슨 환자의 균형, 보행, 낙상효능감에 미치는 효과크기를 알아보고자 메타분석을 실시하였다. PICO 방식에 의해 대상자는 파킨슨환자, 중재는 가상 현실과 e-운동 프로그램, 대조군은 대면 환경에서의 운동 프로그램 적용이나 중재를 적용하지 않은 그룹, 결과는 균형, 보행, 낙상효능감으로 하였다. 조사기간은 2021년 1월부터 2월사이로 2달간이었으며, 최종 5편을 선정하여 메타분석을 실시하였다. 질 평가 도구로 무작위 대조군 연구에 사용되는 ‘비뚤림 위험’ 도구를 사용하였다. RevMan프로그램을 사용하여 비대면 운동프 로그램에 대한 효과 크기를 알아보았다. 메타분석 결과, 균형에 대한 효과 크기는 1.27(SMD=1.27; 95% CI 0.72 to 1.83)(Z=4.51, p<0.001), 낙상감에 대한 효과 크기는 0.52 (SMD=0.52; 95% CI -0.000 to 1.03) (Z=1.96, p=0.05), 보행에 대한 효과크기는 -0.40 (SMD=0.40; 95% CI -1.00 to 0.10)(Z=1.32, p>0.05) 이었다. 5편의 분석 문헌에서 파킨슨 환자에게 비대면 운동프로그램을 적용시 대면 운동프로그램에서 보다 균형과 낙상효능감 향상에 효과 가 있었고 보행에는 효과의 차이가 나타나지 않았다. 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.

iO2 thin films were deposited on glass slides through PECVD with TTIP as a precursor and argon as a carrier gas; their photocatalytic characteristics were investigated. The films were amorphous when deposited at low temperatures, but crystalline with anatase structures at temperatures higher than 300 oC. The film deposited at 400 oC and 5 W exhibited excellent adhesion to the substrate and the best photocatalytic activity. The photocatalytic activity was evaluated based on the degradation efficiency of MB and the bactericidal effect against E. coli under UV-A light. The concentration of MB reduced from 5.0 to 3.5 ppm in 3 h; 99 % of E. coli (2 × 105 CFU/mL) was killed in 1 h.
