Life style and home environment are associated with racial disparities of asthma and allergy in Northeast Texas children

A high prevalence and racial disparities in asthma and allergy have been observed in American children. This study aimed to identify risk factors for asthma and allergy among children, and their contribution to racial disparities in allergy prevalence. A population-based cross-sectional study was carried out among children aged 1-8 years in Northeast Texas 2008-2009. The health conditions, life style and home environment of 3766 children were surveyed by parental questionnaires through e.g. daycares, elementary school, and medical clinics. Among participants who indicated their ethnicity, 255 were Mexican-Americans, 178 Afro-Americans and 969 Caucasians. Afro-American children had a significantly higher prevalence of asthma and eczema. Caucasian had the highest prevalence of rhinitis. Compared to Mexican-American children, Afro-American and Caucasian children were breast fed shorter time, more often went to day care center, had pets and environmental tobacco smoke exposure at home more often. For all children, being at a day care center, being exposed to dampness and environmental tobacco smoke at home were strong risk factors for asthma and allergy. Central air conditioning system was associated with an increased prevalence of wheeze among Mexican-American children, while pets were associated with an increased risk of rhinitis among Afro-American and Caucasian children. Caucasian children were generally not healthier than relatively poor Mexican-American children. Differences in the prevalence of asthma and allergy between races cannot be explained by socioeconomic status only. Life style and home environmental exposures are important risk factors for asthma and allergy in Northeast Texas children.     

“娱乐性”——动画艺术本质解读

动画通过夸张、风趣幽默的表现手法打破现实世界的既定框架,契合了人们对精神解放、自由的追求,表达了人们对美好生活的向往。娱乐性是动画作品诞生的原动力,是动画片尤其是商业动画片存在、成功的本质因素。我们应该颠覆"寓教于乐"中"乐"为途径"教"为目的旧观念,卸下中国动画背负了多年的沉重的教化功能这个包袱,轻松上路,让"娱乐"带领中国动画走得更远更好。

虚拟家电技术研究

针对网络家电功能不易扩展的问题,提出了基于计算机(或嵌入式计算机)中间软件的虚拟家电技术方案。通过归纳白色家电(小家电)基本的功能建立网络家电功能向量表。分析网络家电功能向量表,使表中的功能和网络虚拟数字/模拟通向相对应。设计对家庭网络虚拟数字/模拟通道读写的应用层协议。通过建立虚拟家电的实例表明:虚拟家电对硬件资源要求少,更易于与人工智能方法结合,有利于在家电信息互联基础上的家庭能量和物质资源的整合。     

家用纺织品二次面料设计的魅力及开发研究

Self-regulated learning through writing on computers: Consequences for reading comprehension

The overall aim for the present study was to analyze the consequences for reading ability among the children of a computer supported self-regulated learning environment in grade two. By means of a quasi-experimental design in a natural setting, an experimental group (n = 39) was compared to a control group from a national sample (n = 3409) on reading comprehension. The statistical analyses showed that the experimental group achieved better on reading comprehension both as a group (p < .001) as well as girls (p < .001) and boys (p < .05) separately. The proportion of high achievers was higher, and the proportion of low achievers was lower in the experimental group. In order to explain the level of reading comprehension in the experimental group Structural Equation Modelling (SEM) was used. The main explanatory factor for reading comprehension was writing with β = .44. As a tentative conclusion it was suggested that the extended writing in combination with the self-regulated learning environment can promote reading comprehension in grade two, whereas home literacy had no impact on reading comprehension in this context.     

基于WLAN的域间认证和密钥协商协议

根据无线用户访问对象的不同,分别提出了无线用户和本地域及异地域之间的双向认证协议,包含了用于后续通信的会话密钥协商,具有较好的安全性.协议引入了别名机制,防止了用户信息的泄漏,算法主要涉及对称加密和散列函数计算,相比公钥体制具有更小的计算开销,较适合无线设备.
