肝内胆管结石采用腔镜肝切除术治疗的临床效果分析

目的分析对肝内胆管结石患者采用腹腔镜肝切除术治疗的临床效果。方法选择肝内胆管结石患者作为研究对象,随机分为腹腔镜治疗组和开腹治疗组,各41例。给予腹腔镜治疗组患者进行腹腔镜肝切除术治疗,给予开腹治疗组患者开腹肝切除术治疗,比较两组患者的手术指标、术后恢复情况、临床疗效和术后复发率等。结果腹腔镜治疗组患者术中出血量、止痛药使用情况、下床活动时间、恢复意识时间、术后住院时间、术后并发症发生率、术后复发率均显著低于开腹治疗组,差异均具有统计学意义(P<0.05)。结论对肝内胆管结石患者采用腹腔镜肝切除术治疗效果显著,创伤更小、恢复更快,并发症发生率更低,值得在临床上推广应用。

“专递课堂”辅助教师适应性问题研究

"专递课堂"是云南省开展范围较广、实施规模较大的同步网络在线课堂之一,在实践中涌现出大量有效案例。然而,研究发现,"专递课堂"存在辅班师生适应性差异等问题,导致某些"专递课堂"教学质量并不乐观。基于此,本研究聚焦辅班课堂辅助教师适应性,以红河州泸西县L镇教学点辅助教师为研究对象,运用访谈调查、课堂观察的方法总结现状及存在问题;通过与B镇教学质量较好的教学点进行对比,归纳不适的原因与症结;最后给出相应建议,以期为类似学区辅助教师不适应问题提供解决思路。

Stereo garage parking space allocation model and simulation analysis

Based on grey neural network and particle swarm optimization algorithm,an automated stereo garage decision model is proposed to solve the problems of long waiting queue and low efficiency of automated parking garage.The gray neural network is used to forecast the stay time of the vehicle and particle swarm optimization algorithm is used to allocate the parking spaces in the stereo garage.The proposed stereo garage mathematical model is established on condition that vehicle arrival interval obeys Poisson distribution.The performance of stereo garage is evaluated by the average waiting time,average waiting queue length,average service time and average energy consumption of the customers.By comparing the efficiency indexes of the existing model based on near-distribution principle and the proposed model based on gray neural network and particle swarm algorithm,it is proved that the proposed model based on gray neural network and particle swarm algorithm is effective in improving the efficiency of garage operation and reducing the energy consumption of garage.

释旧出新,融西立中——王宏印《中国传统译论经典诠释》新版述评

王宏印《中国传统译论经典诠释》新版对原版进行了大幅修订和扩充,观之幡然一新。本论部分完善了论述框架的内在逻辑,充实了中西译论的比较阐发和翻译学科建设思考等内容,主要变化是本论外的新增部分,代表了作者近年来利用传统文化资源进行新译学阐述的尝试的成果。余论部分重新认识佛经翻译传统及其理论成果,并论述中国当代译学建设的应对策略和发展趋势,既有宏阔的理论概括,也有精彩的细节描述,接续了余编对文学翻译笔法、表现手法和翻译标准构建系统的阐发。新版在翻译理论、翻译史编撰、译学方法论和学科建设诸方面都有新的开拓和贡献。全书释旧出新、融西立中,体现出独特的中国学术精神和风格气派。
