摘要：In this paper,we describe the design and surgical process of personalised pelvic prostheses fixation through 3D printing according to different Enneking pelvic tumour zones:the ilium(Zone I),acetabulum(Zone II),and pubis and ischium(Zone III).A 3D model of the pelvis was reconstructed using imaging data,and the parameters on the planes of the acetabulum and pelvic incisal margin were *** main body of the pelvic prosthesis was constructed,a porous structure was designed on the bone-prosthesis interface,and the movement paths,lengths,and diameters of screws were *** combining the pathological model and osteotomy guide,limb salvage reconstruction was performed in patients with pelvic *** and postoperative data were compared to verify the prosthesis *** investigation revealed that the long-term survival of pelvic reconstruction prostheses depends on accurate matching with the bone defect area,good initial stability,and a porous structure to allow bone ingrowth.

摘要：为了解决家政物品的收纳问题,提高空间利用率和住户的生活品质。通过问卷调查和用户访谈,分析当前住户在家庭生活中关于家政收纳的现状和存在的问题,提出了家政空间的收纳设计方法。基于家政物品的尺寸规格和人体工程学的要求,通过阳台家政空间的收纳设计实践,得出家政空间急需较为合理且人性化的方法、理论来指导收纳设计。可以从收纳功能合理分类、收纳需求分级和收纳配件等方面研究实践。探析出以人为本的家政空间收纳设计方法,为家政柜产品的设计开发提供了一定程度的设计理论和参考。

摘要：随着时代的发展,建筑作为一种历史符号记载着不同时期的,不同国家的文明与发展,艺术与生活。同时,作为城市中的重要组成部分,建筑在不同时期拥有着不同的艺术表现形式和文化的渗透,其创造出不同的社会价值和历史价值。本文通过对比东西方建筑设计的特点、形式、文化,对建筑发展的形式进行研究分析。通过比对东西方在建筑设计上的差异,进一步了解东西方建筑设计文化的发展、交融和延续。研究建筑文化的差异也对东西方文化交融起发展和推动性作用。

摘要：感染、炎症、肿瘤、先天畸形及严重创伤均可导致骨盆病损。因骨盆结构复杂,对于范围较大、形态复杂的骨盆病损,传统标准化内植物无法重建,或勉强重建但效果不佳。因此,精准设计、结构适配的个性化内植物重建理念成为了突破瓶颈的关键,而与之配套的术前规划、手术辅助设备与手术导航技术,成为决定手术质量与预后的关键。目前,针对3D打印辅助个性化骨盆病损重建的术前规划与手术导航技术的临床应用依然较少。面向未来,如何深入理解、把握3D打印技术的独特优势,推进3D打印精准重建骨盆病损治疗理念的临床转化,将成为骨科个性化治疗领域的重点。

摘要：为了探索定制衣柜购买行为的影响因素及其之间的关联属性,提供给市场加以应用,笔者以定制衣柜为研究对象,分析其市场购买行为现状和并以分析,通过调查分析选定定制衣柜购买行为中的影响最大的几个属性制作成数据样本集,将ID3决策树算法带入样本集中运算,根据数据结果以构建影响定制衣柜购买行为的属性关联的决策树。通过决策树发掘定制衣柜购买行为中“价格”为主要影响属性,同时不同的价格属性与不同的分支属性的紧密关联度也有所对应。企业和市场可以根据该关联性制定相应的策略,从各方面例如设计、营销策划、运营等方面制定贴合属性关联的计划,并加以实施以此提升产品与市场匹配度从而提高市场占有率,也给定制家具产业提供有效科学依据。

摘要：The key to managing fracture is to achieve stable internal fixation,and currently,biologically and mechanically appropriate internal fixation devices are urgently *** excellent biocompatibility and corrosion resistance,titanium–niobium alloys have the potential to become a new generation of internal fixation materials for ***,the role and mechanism of titanium–niobium alloys on promoting fracture healing are still ***,in this study,we systematically evaluated the bone-enabling properties of Ti45Nb via in vivo and in vitro *** vitro,we found that Ti45Nb has an excellent ability to promote MC3T3-E1 cell adhesion and proliferation without obvious *** phosphatase(ALP)activity and alizarin red staining and semiquantitative analysis showed that Ti45Nb enhanced the osteogenic differentiation of MC3T3-E1 cells compared to the Ti6Al4V *** the polymerase chain reaction experiment,the expression of osteogenic genes in the Ti45Nb group,such as ALP,osteopontin(OPN),osteocalcin(OCN),type 1 collagen(Col-1)and runt-related transcription factor-2(Runx2),was significantly higher than that in the control ***,in the western blot experiment,the expression of osteogenic-related proteins in the Ti45Nb group was significantly increased,and the expression of PI3K–Akt-related proteins was also higher,which indicated that Ti45Nb might promote fracture healing by activating the PI3K–Akt signaling *** vivo,we found that Ti45Nb implants accelerated fracture healing compared to Ti6Al4V,and the biosafety of Ti45Nb was confirmed by histological ***,immunohistochemical staining confirmed that Ti45Nb may promote osteogenesis by upregulating the PI3K/Akt signaling *** study demonstrated that Ti45Nb exerts an excellent ability to promote fracture healing as well as enhance osteoblast differentiation by activating the PI3K/Akt signaling pathway,and its good biosafety has been confirmed
