作者： m.Hatami d.d.Ganji Esfarayen University Department of Mechanical EngineeringEsfarayenNorth KhorasanIran mechanical Engineering Faculty Babol University of TechnologyBabolP.O.Box 484Iran

In this study, coupled equations of the motion of a particle in a fluid forced vortex were investigated using the differential transformation method （dTm） with the Pad6 approximation and the differential quadrature method （dO_m）. The significant contribution of the work is the introduction of two new, fast and efficient solutions for a spherical particle in a forced vortex that are improvements over the previous numerical results in the literature. These methods represent approximations with a high degree of accuracy and minimal computational effort for studying the particle motion in a fluid forced vortex. In addition, the velocity profiles （angular and radial） and the position trajectory of a particle in a fluid forced vortex are described in the current study.

背景中国正在完善分级诊疗和家庭医生制度,全科医生人才培养是实现这一制度的核心因素,目前我国全科医生缺口40万,全科住院医师规范化培训是培养高质量全科医生的主要途径。目的通过混合研究方法广而深地了解来自两个城市的两个医院全科住院医师对其接受的全科规范化培训看法的异同,探讨不同规范化培训模式下可能带来的益处。方法应用混合研究方法进行横断面研究。于2019年4月,采用整群抽样法抽取北京大学第一医院和北京大学深圳医院全科住院医师作为研究对象。两个医院均是"5+3"全科住院医师规范化培训基地,其中北京大学第一医院为"四证合一"的试点基地。结果北京大学第一医院共发放问卷39份,回收有效问卷35份,有效回收率89.7%;北京大学深圳医院共发放84份问卷,回收有效问卷70份,有效回收率为83.3%。总体上,全科住院医师感觉到由于选择了全科专业而受到歧视,感觉作为全科医师能力不足。许多住院医师提到教学医师的教学态度较差。北京的住院医师比深圳的住院医师对培训更满意(P=0.001),并觉得全科教学医师有足够的知识(P<0.001)和更合适的教学态度(P=0.004),并且北京大学第一医院住院医师5项工作愿景得分均低于北京大学深圳医院,差异具有统计学意义(P<0.05)。结论这些中国全科住院医师了解培训中需要改进的内容及培训的长项。北京全科住院医师对教学及工作满意度更高,其可以获得高水平教学医师的培训,并可以获得相关证明,提示教育改革可以增强培训力度并促进住院医师有更好的工作愿景。这些发现提示中国的住院医师面临着和国际相类似的情况,同时,也提示规范化培训教学课程的改革可能会带来益处。

第十四届全国泌尿外科学术会议暨第九届全球华人泌尿外科学术会议

作者： department of Urology,Changhai hospital,Shanghai,200433,P.R. China LIANG Jun-hao,m.d. SUN Ying-hao,m.d. XU Chuang-liang,m.d. WANG Lin-hui,m.d. HOU Jian-guo m.d. GAO Xiao-feng,m.d.

Backgrounds and Objectives To evaluate the de-smoke effects of irrigation on surgical smoke generated during laser laparoscopic surgery using ex vivo *** design/materials and methods A hand-piece was devised as both a irrigation tube and a laser fiber holder. The laser system used was a diode pumped continuous wave Thulium YAG laser(Lisa laser products OHG,Katlenburg-Lindau,Germany)emitting at 2.01-μm through a quartz fiber with a core diameter of 365μm. Using a transparent container as experimental m.d.l(approximately 3L in volume),six irrigation rates(0,20,40,60,80 and 100ml/min)were tested combining with four laser power settings(20,30,40 and 50 W). To evaluate the de-smoke efficiency of irrigation,lasing time with effective visibility under different combination of irrigation rates and laser powers were documented,and corresponding smoke generation rates were calculated(= 3L/ lasing time). ANOVA was used to compare difference and significance was indicated at Pmoke generation rate was increased with laser power while decreased with irrigation rate. At all 4 laser powers,smoke generation rates were high ( mean 91.4-306.6 ml/sec ) when no water presented but were significantly decreased(mean 12.6-55.0 ml/sec,Pml/min)and further decreased with higher rates. 40-60ml/min would be a proper range for future clinical practice. Conclusions Irrigation eliminates smoke formation accompanying laser tissue irradiation. It shows promise for future application in laser laparoscopic surgery.

基于物理学基本原理和能量守恒定律的精确检查,导出充满黏性流体多孔固体边界呈连续性要求的边界条件.当孔隙流体具有黏性时,多孔弹性固体就是一个耗散的充满黏性流体的多空固体.孔隙流体的黏性造成的耗散应力准确地表达了边界条件.边界上两种固体连接的不完全,导致孔隙流体的流出,多孔骨料两边微粒运动的不平衡.导出多孔-多孔固体界面孔隙局部连接时的数学模型.在该界面上,滑移的松-紧,以及孔隙开-合,能造成一部分应变能的耗散.数值结果表明,在水和饱和油砂岩之间的界面上,修正的边界条件将影响各向同性多孔介质中折射波的能量.
