摘要：目的:评估金属手术定位片辅助半面短小畸形患者下颌骨截骨的可行性和精确性。方法:选择2018年5至11月间上海交通大学医学院附属第九人民医院整复外科就诊的PruzanskyⅡ型半面短小畸形患儿为研究对象。术前拍摄CT,通过Mimics 19.0设计截骨方案,制备金属手术定位片。术中在手术定位片的引导下,行半面短小畸形的截骨、牵引器置入术。待牵引达到术前设计的长度后结束牵引,拍摄CT。利用逆向工程软件Geomagic Control对术前和牵引完成后的2组下颌骨数据进行配准,随机选取截骨面上的6个点获得误差值,取其平均值记作截骨面之间的距离误差,同时计算截骨面之间的夹角,记作角度误差。距离误差采用2 mm作为参考值,角度误差采用5°作为参考值,在SPSS 25.0中进行单样本t检验,以P0.05)。结论:金属手术定位片辅助半面短小畸形下颌骨截骨具有可行性,精确性较高,有利于术前设计方案在术中实现,术后可获得良好的效果。

摘要：通过对于人类大脑活动的研究来分析消费者对广告和产品的反应的神经营销正在受到新的关注。针对基于脑电波(EEG)的神经营销,提出了一种基于深度学习神经网络的消费者对产品的偏好预测方法。首先,为了提取消费者EEG的特征,采用短时傅里叶变换(STFT)与双调和样条插值,从多通道脑电信号中得到了5个不同频带的EEG形图视频;然后,提出了一种结合5个三维卷积神经网络(3D CNN)与多层长短期记忆(LSTM)神经网络的预测模型,用于从脑电地形图视频预测到消费者的偏好。与卷积神经网络(CNN)模型和LSTM神经网络模型相比,消费者依赖模型的平均准确度分别提高了15.05个百分点和19.44个百分点,消费者独立模型的平均准确度分别提高了 16.34 个百分点和17.88个百分点。理论分析与实验结果表明,所提出的消费者偏好预测系统可以以低成本提供有效的营销策略开发和营销管理。

摘要：位于深圳罗湖区的原金威啤酒厂区被列入工业遗产更新计划,旨在成为深圳最具文化氛围的综合体之一,而园区北门户原易拉罐生产车间由黑家设计组完成建筑立面的更新设计。项目更新升级后将作为集展览、办公、营销功能为一体的商业文化建筑使用。藉由这个看似简单的立面改造项目,建筑师完成了对"遗产"和"立面"的再解读。存续时间的长度、保留的完整度"硬指标"都有可能是决定一座建筑能否被列入"遗产名录"的关键点。
