くるめサマートリートメントプログラムの効果―注意欠陥多動性障害のある超低出生体重児の事例― [PDF]

open access: yes, 2011
超低出生体重児でADHDがある児童のSTP参加の症例である。本児の生活上の問題は,超低出生体重児で生まれたことから親の養育態度が保護的であったが,幼稚園までは園の先生から落ち着きがないという指摘だけであった。しかし,小学校入学後は,学校の準備や日常生活の中での不注意が表 面化してきた。忘れ物が多く,友人関係も仲良しができない状況であった。STPに参加し注意の集中と自分で行動することが可能になった。また,保護者もペアレントトレーニングで本児の接し方を学ぶことで対応できるようになった ...

基于CFD分析的高超声速飞行器上表面优化 [PDF]

open access: yes, 2011
随着航空航天技术的迅猛发展,飞行器的速度和高度不断增加。当飞行器速度达到高超音速时,气动性能的要求就变得越来越显著。因此,对高超声速飞行器进行外形优化设计以达到工程要求的气动性能,就显得尤为重要。外形优化设计是发展高超声速飞行器的关键技术之一。本文以已有的乘波体构型为基础,为获得一个总体性能较优的布局构型,对乘波布局的简化高超声速飞行器进行了上表面的优化设计研究。在巡航条件下,对上表面型线使用B 样条曲线进行参数化,应用了增量参数化方法,优化迭代中应用局部网格重构技术,采用CFD ...
