针对零部件依托印刷电路板(PCB)实现电气互联的不完全模块化产品,提出基于零件质量状态和处置选项的混合式组合再制造(HCR)策略,以处置成本最小化为目标构建再制造组合优化模型,实现个案处置和零件再利用的最优决策。为快速生成和求解优化模型,利用二进制编码逻辑运算提出精确计量处置成本的方法。通过大规模的数值实验,分析零件组合策略对于再制造的适用性和有效性,发现物料成本高但操作成本低的产品适合实施混合式组合再制造,这与现实中广泛存在的消费电子产品的官方翻新品实践一致。通过跨型号(Inter-SKU)组合再制造,相比同型号(Inner-SKU)组合与非组合可分别实现超过10%和30%的成本节约,其中高价值芯片的再利用是成本节约的来源。本文所提出的再制造策略和算法有利于企业的精益再制造,实现资源有效利用,助推我国“双碳”目标的实现。

2023年体外生命支持(ECLS)领域的临床研究关注了静脉-动脉体外膜肺氧合(ECMO)在急性心肌梗死合并心源性休克患者中的应用价值。此外,研究还探讨了静脉-静脉ECMO期间俯卧位的疗效,以及抗凝治疗、输血策略、肥胖对患者预后的影响。清醒状态下静脉-静脉ECMO展现出新的治疗潜力,但其最佳实践方法和管理策略仍需进一步研究。在院内心搏骤停患者中,体外心肺复苏相对于传统心肺复苏表现出更优的生存率和神经功能恢复。体外二氧化碳清除在不同类型的呼吸衰竭患者中疗效不同。未来的研究方向应聚焦如何优化ECLS技术的应用策略、过程管理,深入研究个体化治疗方法,并全面研究如何改善幸存者的远期康复和生活质量。

重症医学是一门对知识、技能以及团队合作和沟通能力要求极高,专门从事危重病症诊疗的学科。然而,重症患者病情复杂且变化快速,常规面授等教学方法存在一定的局限性。虚拟现实(VR)和增强现实(AR)作为新兴的教学方式,能提供一定的模拟教学环境,但无法实现与真实世界的深度交互,教学效果受限。混合现实(MR)是结合了VR和AR特性的一种新技术,能对虚拟世界与真实世界无缝对接,提供一种沉浸式、互动性强的学习体验。目前,MR在医学领域已有初步探索,但在重症医学领域的应用仍处于起步阶段。因此,本文旨在探讨MR的特性和形成,以及在重症医学教学中的应用和潜在价值。
