深度镇静麻醉胃镜检查术后不良反应的影响因素研究

目的探讨丙泊酚联合芬太尼深度静脉麻醉胃镜检查术后患者不适的影响因素。方法随机抽取2010年9月-2010年10月某院深度镇静麻醉胃镜检查术受检者270名,术前采用自制问卷调查,记录受检者术中术后多项指标,分析深度镇静麻醉胃镜检查术术后患者不适的主要影响因素。采用描述性统计分析、χ2检验、单因素非条件logistic回归分析。结果术后不适的影响因素有年龄、BMI、是否患有冠心病、是否曾经做过胃镜检查、术前心理是否紧张、术中是否出现呛咳和躁动、麻醉药物起效时间、术后清醒时间。结论对于年龄较大、肥胖、患有冠心病、以往从未做过胃镜检查、术前紧张、术中出现呛咳躁动、麻醉药物起效时间长的受检者应在术中密切观察其呼吸、循环受抑制情况,并在术后延长观察时间。

大学生弱势群体心理健康状况调查研究——以陕西理工学院贫困生为例

经济贫困大学生是大学生弱势群体的主体。本研究采用大学生心理健康量表（CCSMHS）对陕西理工学院建档贫困大学生进行测试分析,调查结果显示：非弱势群体总体心理健康水平优于弱势群体,尤其是在焦虑、抑郁、自卑、社交退缩、依赖等5方面存在显著性差异;大二学生的心理健康水平优于大三的水平,而性别和城乡之间的差异不显著。并对此分析了具体的原因,提出应完善经济资助与心理资助相结合的资助体系,加强心理咨询工作,对不同类别的大学生弱势群体给予有针对性的指导等对策建议。

How to get out of the prisoners�� dilemma: Educational resource allocation and private tutoring

This paper analyzes the behavior of families in China regarding private tutoring, applying game theory to its discussion of their actions. It finds that families will definitely give their children private tutoring after school in order to obtain better educational opportunities in situations where the distribution of educational resources is uneven. According to game theory, overuse of private tutoring after school will waste societal resources and negatively affect all the players in the game. It is argued that a key strategy to reduce private tutoring after school is to close the gaps in state provision of education.     

Lumped parameter model for resonant frequency estimation of a thermoacoustic engine with gas-liquid coupling oscillation

Gas-liquid coupling oscillation is a novel approach to reducing the resonant frequency and to elevating the pressure amplitude of a thermoacoustic engine. If a thermoacoustic engine is used to drive low-frequency pulse tube refrigerators, the frequency matching between the thermoacoustic engine and the refrigerator plays an important role. Based on an acoustic-electric analogy, a lumped parameter model is proposed to estimate the resonant frequency of a standing-wave thermoacoustic engine with gas-liquid coupling oscillation. Furthermore, a simplified lumped parameter model is also developed to reduce the computation complexity. The resonant frequency dependence on the mean pressure, the gas space volume, and the water column length is computed and analyzed. The impact of different working gases on the resonant frequency is also discussed. The effectiveness of the models is validated by comparing the computed results with the experimental data of the gas-liquid coupling oscillation system. An increase in the mean working pressure can lead to a rise in the resonant frequency, and a lower resonant frequency can be achieved by elongating the liquid column. In comparison with nitrogen and argon, carbon dioxide can realize a lower frequency due to a smaller specific heat ratio.

Screening study of transition metal oxide catalysts supported on ceria-modified titania for catalytic oxidation of toluene

Six transition metal oxides were added in ceria-modified titania using a sol-gel method for catalytic oxidation of toluene. An MnOx based catalyst was found to be the most active one, with which toluene could be decomposed completely at 200 °C. The greatest Mn/Ti and molar ratio of the mobile oxygen to the total oxygen concentration, together with a large surface area and a low reduction peak-starting temperature, would result in its best activity in toluene oxidation.
