简介：瓷电的设备(小便)例如当前的变压器，是批评的在过去的地震期间驱动供应系统，而是它的地震表演一直不是令人满意的。这份报纸学习小便的二种典型类型的地震表演并且基于多重调节集体dampers(MTMD)为小便建议一个抑制方法。抑制包含三个集体单位的设备的MTMD，把一个三元组称为调节质量更潮湿(TTMD)，被设计并且生产。通过饮料桌子测试和有限元素分析，PEE的动态特征被学习，抑制方法的MTMD的有效性被验证。到抑制效率的MTMD冗余的质量的不利影响被学习，相关方程被导出。MTMD坚韧性通过调整TTMD控制频率被验证。当山峰地面加速远超过设计价值时，TTMD的抑制有效性被学习。两饮料桌子测试和有限元素分析显示MTMD在attenuating小便有效、柔韧地震回答。当PGA远超过设计价值时并且当控制偏差被考虑时，TTMD仍然保持有效。

简介：AbstractObjective:Health-care workers (HCWs) in Indonesia have been participating in the war against the coronavirus disease-2019 since March 2020. Ever since HCWs were exposed to the regular use of personal protective equipment (PPE) with varying levels and maintain hand hygiene more as recommended by the World Health Organization. Adverse skin reactions to PPE in Indonesia has yet to be acknowledged. This study aimed to study the prevalence and characteristics-, possible risk factors-, and suggest possible solutions towards adverse skin reactions to PPE among HCWs in a multi-center setting of Indonesia.Methods:A cross-sectional survey was conducted online among HCWs in the Siloam Hospitals Group of Banten province. HCWs of Banten Province were surveyed from June 1 to August 31, 2020. The data was obtained using avalidated online survey questionnaire including (1) demographic characteristics; (2) occupational-related characteristics; (3) adverse skin reactions.Results:A response rate of 40.2% was obtained and 200 valid respondents were yielded. The mean age of respondents was (26.94 ± 7.23) years old. Adverse skin reactions (66.5%) were reported primarily in female (73.7%) working as doctors (82.7%) of a non-referral center for coronavirus disease-2019 (60.2%) wearing level 2 and 3 PPE (43.6% and 37.6%, respectively). The cheeks and chin was the most common site involved (69.9%) with dryness/tightness (63.9%) and acne (77.4%) as the highest symptoms and signs reported. Sex, age group classification, level of PPE worn, hand hygiene frequency, and duration of PPE worn daily were factors considerably associated with adverse skin reactions to PPE (P < 0.05).Conclusions:Adverse skin reactions to PPE are common among HCWs in Indonesia. Comprehensive strengthening of the skin condition and awareness on adverse skin reactions should be advocated.
