The purpose of this study was to investigate the effects of ten weeks table tennis training on dynamic visual acuity (DVA) on general population. Fourteen collegiate students were volunteered and ransom assigned equally as training group or control group. Training group underwent a ten weeks table tennis training program with 500 balls twice a week, but control group did not received any kind of exercise training during this period. DVA was measured with commercial software Athlevision to evaluate in four directions: right, left, up, and down, and calculated as horizontal (DVA-H), vertical, and total (DVA-T) abilities. Results reveal that training group showed significant improved DVA abilities in DVA-L (2.29±0.49 vs. 3.14±0.69, F = 7.09, p < .05), DVA-H (4.71±0.76 vs. 6.29±1.25, F = 9.64, p < .05), and DVA-T (9.57±0.98 vs. 11.29±1.60, F = 6.17, p < .05) after ten weeks table tennis training. The finding suggested that ten weeks regular table tennis training can improve the DVA ability on general population. It is possible that during this training, participants have to continual focusing/tracking the moving ball, and correctly predict the distance/space between the line, net, and the direction of coming ball, therefore, improved the rapid senses of fovea and the control of oculomotor system. 本研究目的在於探討十週規律桌球運動訓練對人體動體視力的影響。14位大學生自願參與並隨機分為桌球訓練組與一般組， 桌球訓練組需進行連續10週，每週2次，每次500球之桌球訓練，一般組則無接受任何運動訓練，兩組皆於訓練前後以Athlevision測試軟體評估其動體視力的變化。結果發現訓練後桌球組向左 (2.29±0.49 等級 vs.3.14±0.69 等級, F=7.09, p<.05)、水平 (4.71±0.76 等 級 vs.6.29±1.25 等級, F=9.64, p<.05) 與整體 (9.57±0.98等級 vs.11.29±1.60 等級, t=6.17, p<.05) 等動體視力表現有顯著改善。結論：規律桌球訓練可改善人體的動體視力表現，其機轉應與桌球訓練時需以視覺持續注視或追蹤高速旋轉移動的球體，且要正確判斷持拍與來球之間的距離、邊端線、網子與對方的位置，因而提升眼球中央小窩快速移動球體知覺與眼球控制能力。

Background: Pressure ulcers are the common conditions among patients hospitalized in acute and chronic care facilities and impose significant burden on patients, their relatives and caregivers. Now days, pressure ulcers are recognized worldwide as one of the five most common causes of harm to patients and preventable patient safety problem. It is also increasingly described as an indicator of the quality of care provided by health care organization. However, pressure ulcers are largely preventable. All patients who are identified as being at risk should have a management plan to prevent development of pressure ulcer, optimize healing, and prevent complications of existing pressure ulcer. Objectives: 1. To assess the level of practice regarding prevention of pressure ulcer in bedridden patients among nurses. 2. To determine the association between pre-test practice scores of nurses regarding prevention of pressure ulcer in bedridden patients with selected sample characteristics. Methodology: The research design used for this study was non – experimental descriptive design. The study was conducted at a tertiary hospital in Bengaluru, Karnataka, India. Population comprises of nurses (staff nurses and student nurses) working in a selected hospital. The sample size selected for this study consists of 60 nurses (staff nurses -24 and student nurses -36) who were working in medical, surgical wards and Intensive Care Units (ICUs). Nurses providing care to the patients who are bed ridden for more than 48 hours were included in the study. Non – probability purposive sampling technique was used to select the samples. The tool used in this study was socio-demographic profile of nurses (separate tool for staff nurses and student nurses) and observational checklist to assess the practice. Result: The overall practice scores of the 60 nurses revealed that 40(66.67%) had good practice, whereas 20(33.33%) samples had average practice and none of them had poor practice. Among of 24 staff nurses; 20(83.33%) had good practice, whereas 4(16.67%) had average practice and none of them had poor practice. Out of 36 student nurses; 20(55.56%) had good practice, whereas 16(44.44%) samples had average practice and none of them had poor practice. It was found that among socio-demographic variables none had association with the practice of staff nurses and student nurses too. Conclusion: The study concluded that continuing education programmes are needed to improve the practices of nurses. Nurses must be motivated to provide back care and position change every second hourly in bedridden patients.
