高等教育国际化已成为一个非常广泛多样的概念,它在机构、国家和区域层面有着不同定义,并且随时间的推移而演变,以应对不断变化的环境和挑战。文章阐述对“高等教育的国际化”和“高等教育中的国际化”的不同看法、理解,以及关键的范式转化,并得出批判性反思——未来十年,国际化作为一个概念和应对全球大变局的实践,需要从短期的新自由主义转向长期的社会利益,从仅造福于少数精英的国际教育转向全球全民学习,从西方范式转向全球平等概念。

近来的研究表明,由于围术期神经肌肉阻滞管理不当,肌肉松弛药(肌松药)残留阻滞及其术后并发症的发生率居高不下。需要重视神经肌肉功能监测仪、肌松药及其拮抗剂的合理应用,以利于改善神经肌肉阻滞管理。欧洲麻醉和重症监护学会(European Society of Anaesthesiology and Intensive Care,ESAIC)首次发布围术期神经肌肉阻滞管理临床指南,旨在为临床医生提供最佳医疗管理的循证建议,以提高围术期患者安全。本指南主要聚焦在3个临床问题:肌松药是否有助于成人气管插管?神经肌肉阻滞深度是否影响腹部手术患者的预后?肌松药残留阻滞的诊断和治疗策略有哪些?根据PICO原则(患者、干预、对照、结局;patient,intervention,comparator,outcome;PICO)构建临床问题并进行文献检索。初始纳入的临床研究为24 000篇,采用逐步筛选策略,最终临床研究88篇纳入指南分析。应用GRADE方法学(Grading of Recommendations,Assessment,Development and Evaluation,GRADE)对结局指标证据、质量等级进行评价。运用两轮德尔菲法收集专家组建议并形成统一推荐:R1推荐应用肌松药辅助气管插管(1A)。R2推荐应用肌松药以减少气管插管导致的咽部和(或)喉部损伤(1C)。R3推荐在快速顺序诱导插管(rapid sequence induction intubation,RSII)时使用短效肌松药,例如琥珀胆碱1 mg/kg或罗库溴铵0.9~1.2 mg/kg(1B)。R4推荐在需要改善外科手术条件时,加深神经肌肉阻滞深度(1B)。R5尚无足够的证据推荐深度神经肌肉阻滞可减轻术后疼痛或降低围术期并发症的发生率(2C)。R6推荐在拇内收肌处刺激尺神经,定量监测神经肌肉阻滞深度以排除肌松药残留阻滞(1B)。R7推荐应用舒更葡糖钠逆转甾体类肌松药(罗库溴铵、维库溴铵)诱导的深、中及浅度神经肌肉阻滞(1A)。R8推荐在使用新斯的明前,TOFr自行恢复至>0.2,并继续定量监测神经肌肉功能,直至TOFr超过0.9(1C)。

In minimally invasive surgery, one of the main objectives is to ensure safety and target reaching accuracy during needle steering inside the target organ. In this research work, the needle steering approach is determined using a robust control algorithm namely the integral sliding mode control(ISMC) strategy to eliminate the chattering problem associated with the general clinical scenario. In general, the discontinuity component of feedback control input is not appropriate for the needle steering methodology due to the practical limitations of the driving actuators. Thus in ISMC, we have incorporated the replacement of the discontinuous component using a super twisting control(STC)input due to its unique features of chattering elimination and disturbance observation characteristics. In our study, the kinematic model of an asymmetric flexible bevel-tip needle in a soft-tissue phantom is used to evaluate stability analysis. A comparative study based on the analysis of chattering elimination is executed to determine the performance of the proposed control strategy in real-time needle steering with conventional sliding mode control using vision feedback through simulation and experimental results. This validates the efficacy of the proposed control strategy for clinical needle steering.

we use a two-dimensional model of polygonal particles to investigate granular ratcheting. Ratcheting is a long-term response of granular materials under cyclic loading, where the same amount of permanent deformation is accumulated after each cycle. we report on ratcheting for low frequencies and extremely small loading amplitudes. The evolution of the sub-network of sliding contacts allows us to understand the micromechanics of ratcheting. we show that the contact network evolves almost periodically under cyclic loading as the sub-network of the sliding contacts reaches different stages of anisotropy in each cycle. Sliding contacts lead to a monotonic accumulation of permanent deformation per cycle in each particle. The distribution of these deformations appears to be correlated in form of vortices inside the granular assembly.

The anisotropic plastic deformation behavior of as-extruded ZK60 magnesium alloy at room tempera-ture (RT) was investigated by compressive and tensile testing in different directions, i.e. the loading axis oriented at 0°, 45° and 90° to the extrusion direction. The relationship between texture and plastic deformation behavior were examined. The results show that the extruded ZK60 alloy exhibits a strong ring fiber texture. The mechanical properties are strongly orientation dependent. In tension testing, the 0° specimen exhibited higher yield strength and lower elongation. In compression testing, however, ZK60 alloy exhibited almost the same yield strength in three directions. The anisotropic plastic defor-mation behavior is due to strong fiber texture and the lower symmetry of the hexagonal close packed (hcp) structure of ZK60 alloy. The correlation between texture and mechanical behaviour offers the possibility to improve the mechanical properties of magnesium alloy by optimization of the material production process.
