简介：这篇文章在优秀通货膨胀的存在下面与消费者参考质量效果学习联合定价和动态产品质量投资的一个问题。最佳的控制模型被构造与一个有限优秀投资能力最大化全部的利润，在需求对历史的产品质量水平敏感的地方。为有限、无限的计划地平线的最佳的优秀投资策略被根据Pontryagins最大的原则解决这些最佳的控制模型分别地给，它随着时间的过去与引用质量效果使最佳的优秀投资的准确轨道能被描绘。另外，一个有效算法被设计为系统产生最佳的联合定价和动态优秀投资政策。有限计划地平线和无限的计划地平线的策略之间的主要差别是后者是一个常数。我们的学习显示公司在整个计划地平线一路上增加优秀投资从来不是最佳的。当考虑参考质量的影响时，优秀投资的水平更高。而且，数字例子被给说明理论结果的正当。另外，敏感分析被执行显示出系统参数怎么影响最佳的政策，并且一些经理的建议被介绍。

简介：AbstractBackground:We sought to explore an optimal clinical nursing mode following a hybrid surgery for cerebral arteriovenous malformation.Methods:Patients with complex cerebral arteriovenous malformations seen in our neurosurgery department from January 2016 to December 2017 were prospectively enrolled. The hybrid surgery protocol included "angiographic diagnosis, surgical resection, and intraoperative angiographic evaluation" and "angiographic diagnosis and embolization, surgical resection, and intraoperative angiographic evaluation" . The patients were randomly stratified into intensive care group and routine care group. After surgery, intensive or routine care was provided, and the prognosis of patients was evaluated, with a subsequent comparative analysis.Results:A total of 109 cases were divided into the routine nursing group (n = 54 cases) and intensive nursing group (n = 55 cases). There were no significant differences between the two groups in baseline data before surgery. Postoperative lung infection in the intensive nursing group was significantly less frequent than those in the routine nursing group (5.5% vs. 18.5%, P=0.039) with pulmonary infection and lower extremity venous thrombosis (5.5% vs. 24.1%, P=0.006). The average hospital stay in the intensive nursing group was 14.4 ± 5.78 days, which was significantly lower than that in the routine nursing group (19.3 ± 6.38 days, P=0.013). At 3 months’ follow-up after surgery, the Generic Quality of Life Inventory-74 (GQOLI-74) dimension score and GQOLI-74 total score in the enhanced group were significantly better than those in the routine nursing group (P=0.017 and 0.023, respectively).Conclusions:Intensive postoperative nursing can improve the safety of patients after hybrid surgery, reduce the postoperative complications and the average length of hospital stay, and improve the quality of life of patients.
