 [PDF]

若林, 邓燕, 秦雪
Advances in Education (AE) , 2015, DOI: 10.12677/AE.2015.53007
Abstract:
当前,随着医学科技发展和本科教育体制的逐渐改革,如何对本科实习生人员进行合理的培养,使他们能够进入工作岗位或继续攻读研究生前,建立起良好的科研思维、科研积极性和科研作风,对加强临床科研素质的培养乃至提高我国的医疗科研水平具有重要意义。我院作为医科大学的第一附属医院,具有良好的科研资源与平台,作者结合自身及周围同事几年来在检验工作之余指导本科生实习生参与科研项目的经历,总结了一些体会,供检验同行借鉴与推广应用。
Nowadays, as the development of medical science and technology and the reformation of under-graduate education system, how to culture undergraduate interns better than before, and how to build up a good medical research thinking and style before working and going on postgraduate are very important to strengthen the cultivating quality of clinical research and even improve medical research in our country. As the first affiliated hospital of medical university, our hospital has a good resource and platform of medical research. Therefore, on the basis of the guidance for clinical laboratory undergraduate interns to participate in research activities during spare time of working by us, I and my colleagues have summarized some experience for application.
基于博弈理论的产权式酒店投资风险研究
若林
科技进步与对策 , 2010,
Abstract: 作为一种旅游与房地产相结合的物业,产权式酒店模式自引入之日起便开始风靡全国。在国内著名旅游城市及经济繁荣城市从星星之火已发展为燎原之势。然而,由于产权式酒店的各方利益者众多、信息不对称的情况严重,产权式酒店也成为了目前我国不动产投资市场上投资风险最大的产品之一。从博弈理论的角度出发,探讨了产权式酒店的各方利益主体之间的博弈策略和博弈行为,提出建立健全担保机制,使其成为开发商的信号传递机制,从而避免了产权式酒店投资领域的逆向选择和道德风险问题,以推动产权式酒店投资的和谐、健康发展。产权式酒店博弈理论信息不对称信号传递机制担保机制

Abstract: 工程款拖欠问题是影响我国建设领域投资效率和社会经济秩序的顽疾,而信息不对称导致的逆向选择正是这一问题的症结所在。通过分析不同担保费率条件下的均衡状况,探讨了业主支付担保作为信号传递机制的实现条件和作用机理;建立了业主支付担保机制模型,基于完善的信用信息披露和评级制度,担保机构根据申请人的信用等级实行差别费率,诱使或迫使不同类型的业主采取相异的决策,从而避免建设领域的逆向选择问题。工程款拖欠业主支付担保机制不对称信息逆向选择信号传递机制

Abstract: 动脉粥样硬化性心脏病是严重危害人类生命健康的心血管疾病。近年来其主要的治疗手段是将血管内支架植入到病变部位,支撑血管并重建血运。然而,大量研究表明,血管内支架植入的介入操作、抗增殖药物释放均会对血管内皮造成极大的损伤,大大增加了支架内再狭窄和晚期血栓形成的风险。维持血管内皮的完整和正常功能可明显降低支架植入带来的一系列风险。研究表明,干细胞动员、归巢、分化、增殖是血管内支架植入后血管内皮修复的主要机制,多种血管内因子、力学微环境变化等均参与此过程,进而影响植入部位的再内皮化。本文对支架植入造成血管内皮损伤的过程、损伤后的修复机制及其影响因素等进行详细阐述,并分析总结其修复策略,为深入理解支架内再狭窄、血管内皮化延迟和晚期血栓形成的机制以及新型药物洗脱支架和生物可降解支架的设计提供参考。
Coronary atherosclerotic heart disease is a serious threat to human life and health. In recent years, the main treatment for it is to implant the intravascular stent into the lesion to support blood vessels and reconstruct blood supply. However, a large number of experimental results showed that mechanical injury and anti-proliferative drugs caused great damage after stent implantation, and increased in-stent restenosis and late thrombosis risk. Thus, maintaining the integrity and normal function of the endothelium can significantly reduce the rate of thrombosis and restenosis. Stem cell mobilization, homing, differentiation and proliferation are the main mechanisms of endothelial repair after vascular stent implantation. Vascular factor and mechanical microenvironmental changes in implanted sites have a certain effect on re-endothelialization. In this paper, the process of injury caused by stent implantation, the repair mechanism after injury and its influencing factors are expounded in detail. And repairing strategies are analyzed and summarized. This review provides a reference for overcoming the in-stent restenosis, endothelialization delay and late thrombosis during the interventional treatment, as well as for designing drug-eluting and biodegradation stents.

Abstract: 运用多主体演化博弈分析方法,构建建筑市场信用链模型,通过剖析建筑市场多行为主体的自发博弈过程,探讨建筑市场信用链的演化机理和演进路径。在此基础上,提出信用链优化的目标和途径。分析结果表明:建筑市场信用链的优化取决于信用收益的合理分配和行为主体的互信度。因此,需构建建筑市场信用机制,通过信用链淘汰信用不良的行为主体。演化博弈;信用链;信息共享;激励约束
扁平钢箱梁U肋焊接残余应力数值模拟分析
Numerical simulation for the residual stress of U-rib welding onto the flat steel box girder

Abstract: 已建成的扁平钢箱梁桥在运营过程中发现一些与结构、构造和制造相关的病害,并且随着服役时间的增长越来越突出。其原因是扁平钢箱梁结构采用薄板组焊而成,因此,扁平钢箱梁在未受力之前,便已存在着由于焊接所产生的应力场和变形场, 导致扁平钢箱梁普遍出现裂纹等病害。运用热结构耦合法对扁平钢箱梁U肋与桥面板交接处焊接的温度场和应力场进行数值模拟计算分析,并得到焊接残余应力的分布规律,为进一步分析结构病害与加固设计提供依据。
The flat steel box girder is commonly used for long-span cable-stayed bridges. the structural complexity, construction details and manufactures cause damage to the bridge and the damages seriously grow overtime. The main reason for these damages is that welding technology of flat steel box girder with thin plates and rib elements produces residual stress and strain fields during the welding process, and further more welding cracks commonly appear. In this study, thermal-structural couple methods was adopted to numerically simulate the welding high temperature fields and the stress fields at the joint of U rid and decks of a flat steel box. The welding residual stress distribution was studied as well for further analyzing on the structural damage and strengthening design strategies.
