目的:家庭抗逆力能帮助早产儿家庭应对困难和逆境,可促进家庭成员之间的联系和支持以及个人心理健康的提升。本文调查新生儿重症监护病房(Neonatal Intensive Care Unit,NICU)出院早产儿家庭抗逆力的现状及影响因素,为日后干预方案的制订提供参考依据。方法:通过方便抽样的方法,选取2022年11月至2023年1月收治于同济大学附属妇产科医院NICU治愈出院的192例早产儿及192例早产儿父母中的主要照护者为研究对象,基于生态系统理论应用中文版家庭抗逆力量表简化版(shortened Chinese version of the Family Resilience Assessment Scale,FRAS-C)、简易应对行为问卷(SimplifiedCopingStyleQuestionnaire,SCSQ)、Zarit照顾负担量表(ZaritCaregiver Burden Interview,ZBI)、中文版育儿胜任感量表(Chinese Version of Parenting Sense of Competence Scales,CV-PSOC)、家庭关怀度测评量表(Family Concern Index Questionnaire,APGAR)和社会支持评定量表(the Social Support Rating Scale,SSRS)对其进行调查。结果:NICU出院早产儿家庭抗逆力总评分为96.87±6.20,应对方式、育儿效能、家庭关怀度和社会支持均是其主要的影响因素(均P<0.05),可解释其89.6%的变异度。结论:NICU出院早产儿家庭抗逆力尚需提高,受到生态系统中各系统层面因素的共同作用,微系统层面对家庭抗逆力的预测作用最强,其中应对方式是关键因素,提示医务工作者应在早产儿从NICU到家庭过渡阶段有意识地引导早产儿家庭采取积极的应对方式,以提高NICU出院早产儿家庭的抗逆力水平。

目的探讨新生儿重症监护室(NICU)出院早产儿家庭抗逆力(FRAS)的发展轨迹类别及预测因素,为后续精准护理干预方案的制定提供参考依据。方法选取2022年11月至2023年8月收治于同济大学附属第一妇婴保健院NICU治愈出院的161例早产儿及早产儿父母中的主要照护者为研究对象,分别于早产儿出院后1周(T0)、矫正1月龄(T1)、矫正3月龄(T2)及矫正6月龄(T3)四个时间节点其FRAS水平,使用混合增长模型(GMM)识别潜在轨迹类别,并采用多元Logistic回归分析其预测因素。结果本研究共识别出3条NICU出院早产儿FRAS轨迹,分别为“高家庭抗逆力稳定组”(6.2%)、“中等水平家庭抗逆力上升组”(6.8%)和“低家庭抗逆力持续组”(87.0%)。Logistic回归显示,育儿胜任感、社会支持及家庭关怀度是NICU出院早产儿FRAS发展轨迹类别的预测因素(P<0.05)。结论矫正6月龄内NICU出院早产儿家庭FRAS的发展轨迹存在异质性,存在3条不同的发展轨迹,大部分FRAS起始水平低的早产儿家庭出院后并未得以改善,是研究者应当重点关注和优先干预的人群,护理管理者基于其预测因素,在有限的医疗资源下给予精准而有针对性的护理干预方案,从而提高干预效果并优化资源利用。

2023中国汽车工程学会年会暨展览会

作者： zhao Qian zhao lijin Xing Jie Duan Zhihui China Automotive (Beijing) Technology Research Institute Co. Ltd. Xiamen Nevc Advanced Electric Powertrain Technology Innovation Center

Firstly,some hybrid powertrain system solutions of mainstream domestic and foreign car companies are introduced,and it is pointed out that a core reason for limited application of P2 parallel scheme in domestic car companies is that dual clutch assembly has always been in the hands of a few international component giants. Then a hybrid dedicated transmission scheme based on eTC is proposed,mainly consisting of an electric torque converter(eTC) and a dual input shaft gearbox. The eTC module includes a planetary mechanism,a motor,and two wet clutches,replacing the dual clutch module. Next,the modes of pure electric drive(EV),differential drive,hybrid drive(HEV),EV to HEV switching,engine & motor alternating drive and gear shifting that the system can achieve are analyzed. Finally,using MATLAB/SIMULINK software,a medium-sized bus is selected to conduct a simulation analysis of power and economy performance of the hybrid system. The results show that the hybrid vehicle has significantly improved power and economy performance compared to the basic one,with a fuel saving rate of over 24%, and has good market application prospects.

文艺领域网络暴力事件的发生,表现为施暴者以道德评判取代文艺批评,对文艺创作者进行个人攻击和侮辱,进而危害文艺批评。在更深层面上,这一现象反映出当下文艺批评的困境和问题,即传统文艺批评面对新文艺现象时的“失语”;网络文艺批评因资本操控和理性的缺失而导致潜在的“暴力”危机。建构有效的文艺批评话语,是摆脱道德话语压制、反击网络暴力的重要路径。

The effects of CEC passes, isothermal holding time and reheating temperature on the microstructure evolution and grain coarsening behaviour of AZ61 magnesium alloy produced by the recrystallisation and partialmelting （RAP） process were investigated. Before partial remelting, as-cast AZ61 alloy was deformed by cyclic extrusion compression （CEC） with one pass and two pass at 330 ℃. After CEC, the microstructure consisted of unrecrystallized grains and deformed eutectic compounds. Increasing isothermal holding time resulted in the formation of spheroidal grains surrounded by liquid films. With increasing the isothermal holding time, the solid grain size increased and the degree of spheroidization was improved. With increasing the reheating temperature, namely increasing liquid fraction, the solid grain size obviously decreased during the period from 560 ℃ to 570 ℃ and then slightly increased after 570 ℃, while the shape factor increased monotonously. During partial remelting, increasing reheating temperature can properly short the isothermal holding time to obtain fine structure. Moreover, increasing the numbers of CEC passes could produce finer semi-solid microstructure. The coarsening behavior of solid grains in the semi-solid state obeys Ostwald ripening and grain coalescence mechanisms. The coarsening rate constant, K, 595 ℃. After CEC plus partial remelting, the ideal and fine was suitable for thixoforming. was 80μm^3.s^-1 for samples partially remelted at semi-solid state structure can be obtained, which
