A note on strong law of large numbers of random variables

In this paper, the Chung’s strong law of large numbers is generalized to the random variables which do not need the condition of independence, while the sequence of Borel functions verifies some conditions weaker than that in Chung’s theorem. Some convergence theorems for martingale difference sequence such as Lp martingale difference sequence are the particular cases of results achieved in this paper. Finally, the convergence theorem for A-summability of sequence of random variables is proved, where A is a suitable real infinite matrix.

In memory of Professor Chen Jiangong(Chen Kien Kwong) on the 120th anniversary of his birth

内镜中心麻醉风险管理方案构建及应用效果研究

目的 构建内镜中心麻醉护理风险管理方案,评估其应用效果。方法 选取2021年1月—2021年11月在医院内镜中心就诊的400位患者作为研究对象,其中干预组200位患者实施内镜中心麻醉护理风险管理方案,对照组200位患者实施常规护理干预。比较两组麻醉相关并发症(呛咳、恶心呕吐、麻醉中低氧、心律失常、低血压、跌倒)发生率,以及对护理工作的满意率。结果 内镜中心麻醉护理风险管理方案实施后,两组患者麻醉相关并发症中的呛咳和麻醉中低氧发生率差异有统计学意义(p<0.05),护理工作满意率差异有统计学意义(p<0.001)。结论 通过构建内镜中心麻醉护理风险管理方案,能够降低医院内镜中心麻醉相关并发症,提高护理工作满意率。
