应用原子吸收光谱法对襄阳地区112例妊娠妇女发样中Zn、Cu、Fe、Ca、Mg、Mn、Se、Pb八种微量元素含量进行测定,并进行统计学分析．结果表明：襄阳地区妊娠妇女发样中主要以缺乏Ca、Zn2种微量元素为主,妊娠妇女缺zn者高达82．89％,缺Ca者达66．07％,微量元素缺乏现象比较严重．部分妊娠妇女存在多种微量元素缺乏问题．妊娠期妇女应合理补充和平衡微量元素,,保证自身健康和胎儿的正常发育．  相似文献   

Gathering the views of children and young people with ASD: a systematic literature review     

Beverley Tyrrell  Kevin Woods 《British Journal of Special Education》2020,47(3):376-398

According to the United Nations Convention on the Rights of the Child, children have a right to have their views listened to, and studies have shown that doing so can improve their motivation and self‐esteem. Accordingly, this systematic literature review sought to investigate how the views of children with an autism spectrum disorder (ASD), who have difficulties with social communication, may be gathered. Searches of electronic databases yielded 20 studies which met the criteria for inclusion. Semi‐structured interviews (SSIs) were popular, but there is tentative evidence that these are better suited to older, or more academically able, participants. Some of the evidence suggests adaptations to make SSIs more accessible to young people with ASD. Initial evidence has also emerged regarding the suitability of focus groups and electronic diaries. More focused evaluation by researchers of the suitability of their chosen data‐gathering methods for participants with ASD would allow broader conclusions to be drawn.  相似文献   

Determination of peak cardiorespiratory fitness parameters in children: which averaging method should we use?     

Joel Blanchard  Samuel Blais  Philippe Chetaille  Michele Bisson  François P. Counil  Thelma H. Girard 《Journal of sports sciences》2019,37(11):1265-1269

The purpose of this study was to identify which averaging methods most accurately measures peak cardiorespiratory fitness (CRF) parameters [peak O₂ uptake (VO₂), peak O₂pulse and peak respiratory exchange ratio (RER)] in a sample of healthy children and adolescents. In this cross-sectional multicenter study, we recruited 278 healthy children aged 12–17 years. We compared the mean peak value of three CRF parameters using the recommended averaging methods (30-second block average) with alternative averaging methods such as moving averages or shorter smoothing periods. We also assessed averaging methods for accuracy by individually reviewing breath-by-breath scatter plots. The 30-second block average method resulted in a lower mean peak VO₂ and in an increased proportion of underestimated peak values. Using a 30-second moving average significantly increased mean peak values which increased accuracy. Similar results were found for peak RER and peak O₂pulse. In conclusion, the currently recommended averaging method (30-second block average) increased the risk of misinterpretation of peak CRF values in children. Using a moving average approach decreased misinterpretation and increased accuracy.  相似文献

传统的动力学:娃娃亲的现代化生存   总被引：5，自引：0，他引：5  

岳永逸 《北京师范大学学报(社会科学版)》2005,(6):69-78

在已经加入WTO,并步入21世纪的今天,“娃娃亲”在中国农村仍以不同的方式存在。显然,这并非仅仅是由于农民的保守、愚昧。在对传统等概念反思的基础上,根据实地调查材料,分析了在河北省梨区存在的换小帖这一现代农村“娃娃亲”的婚约形式与当地习俗、经济和村民心理等之间的密切关系,意在强调传统(民俗)在不同场景中的自我调适,传统的当下性、渐变性、有机性等特征,即传统的动力学。  相似文献
