Apuleia leiocarpa is an environmentally and economically significant Atlantic Forest species threat-ened by ongoing exploitation. The vegetative propagation of the species could be a step forward to enable implanta-tion of clonal seed orchards and multiplication of selected trees but remains unknown to date. This study assessed the mini-cutting technique for propagation of A. leiocarpa and determined the time required for rooting and viable mini-cutting type and sizes. The results show that it is possible to propagate A. leiocarpa with mini-cuttings derived from mini-stumps produced with seeds; the mini-stumps pre-sented regrowth capacity and remained constantly produc-tive for 1 year; 10-cm A. leiocarpa mini-cuttings should remain under misting conditions for at least 40 days, and the vegetative propagation of A. leiocarpa with intermediate 7- to 10-cm mini-cuttings resulted in more vigorous clonal seedlings than smaller mini-cuttings.

自从“放管服”改革概念提出之后,全国各地政府都在推进“放管服”改革.要深化“放管服”改革,实现“数据跑路”代替“群众跑腿”,关键问题是要解决好政务大数据资源共享.广西把深化“放管服”改革作为推动高质量发展的有效抓手,不断提升政务服务效能,持续优化营商环境,于2019年11月出台了相关方案并提出“一池共享”,将政务的数据资源进行整合,构建政务大数据资源池并共享.本文针对广西政务大数据资源在共享过程中遇到的障碍进行分析,探讨在“放管服”改革过程中典型案例成功的原因,并提出相应的对策建议.

用户体验是产品设计专业研究用户需求的方法之一,用户需求影响产品形态、功能及结构.本文以用户体验为理论导向,针对牙科医生给牙科患者诊断、治疗、手术等存在的问题进行调研,结合患者和医生在使用牙科椅时出现的生理、心理问题,患者因身高因人而异出现不同的人机问题,以及医生在诊治时出现的物品摆放和操作问题进行探讨.结果表明,从人与牙科椅功能和造型之间关联性的角度进行牙科椅再设计,从用户的真实体验出发,提升医疗效率,满足患者需求,可以增加医生与患者之间的信任度.
