In China, Type 2 diabetes mellitus (T2DM) is increasingly affecting people's health. Although many risk factors related to T2DM have been researched, the association between social relationships and risk management of T2DM in China has not been fully researched. Therefore, we obtained 2,969 valid cases from the National Chinese Medicine Clinical Research Base-Key Disease of Diabetes Mellitus Study to evaluate the role of social relationships in the risk management of T2DM. We first establish an indicators system of social relationship factors and then propose a comprehensive method that integrates subjective (analytical network process) and objective (entropy weight method) evaluations to rank the importance of the 17 social relationship factors that were the most important and commonly used. The results suggest that different social relationship factors have different effects on the risk management of T2DM. Patients and health workers should pay more attention to the high-benefit factors and thus improve the efficiency of the risk management of T2DM. These findings provided theoretical support for patients and health workers by developing the positive effects of social relationships in improving the risk management of T2DM to the fullest degree.  相似文献

Pressure sensors that can both directly visualize and record applied pressure/stress are essential for e‐skin and medical/health monitoring. Here, using a WO3‐film electrochromic device (ECD) array (10 × 10 pixels) and a ZnO‐nanowire‐matrix pressure sensor (ZPS), a pressure visualization and recording (PVR) system with a spatial resolution of 500 µm is developed. The distribution of external pressures can be recorded through the piezotronic effect from the ZPS and directly expressed by color changes in the ECD. Applying a local pressure can generate piezoelectric polarization charges at the two ends of the ZnO nanowires, which leads to the tuning of the current to be transported through the system and thus the color of the WO3 film. The coloration and bleaching process in the ECD component show good cyclic stability, and over 85% of the color contrast is maintained after 300 cycles. In this PVR system, the applied pressure can be recorded without the assistance of a computer because of the color memory effect of the WO3 material. Such systems are promising for applications in human‐electronic interfaces, military applications, and smart robots.  相似文献

The effects of the pubertal transition on behavior problems and its interaction with family and neighborhood circumstances were examined with a sample of 867 African American children 10-12 years of age. Pubertal development status, pubertal timing, and primary caregivers' parenting behaviors were significantly related to affiliation with deviant peers and externalizing behaviors. Externalizing behavior among early-maturing children was associated positively with primary caregivers' use of harsh-inconsistent discipline and negatively with nurturant-involved parenting practices. Disadvantaged neighborhood conditions were significantly associated with deviant peer affiliation. The effect of pubertal transition varied according to family and neighborhood conditions: Early-maturing children living in disadvantaged neighborhoods were significantly more likely to affiliate with deviant peers. Early-maturing children with harsh and inconsistent parents were significantly more likely to have externalizing problems. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

The occurrence and co-occurrence of depressive symptoms and conduct problems were examined in the context of parenting behaviors in a community-based sample of 897 African American children and their primary caregivers using a multi-informant, longitudinal design. Parenting behaviors and clinical symptoms were assessed in 2 waves, when the children averaged 10.5 and 12.3 years of age. Parenting behaviors differed significantly according to a child's symptomatology; (a) that is, when a child exhibited no depressive or conduct problems, (b) depressive problems only, (c) conduct problems only, or (d) co-occurring depressive and conduct problems. When parenting behaviors were examined according to changes in children's symptom levels, children whose symptoms increased over time reported increases in hostility and harsh-inconsistent parenting and decreases in warmth and nurturant-involved parenting.

Effects of early physical maturation and accelerated pubertal changes on symptoms of major depression were examined in 639 African American children. Three rival hypotheses, early timing, off-time, and stressful change, were tested using 2 waves of data (mean ages = 11 and 13 years). The pubertal effect operates differently according to children's gender and age. For girls, early maturation was consistently associated with elevated levels of depressive symptoms. For boys, early maturers manifested elevated levels of depression only at age 11, but these symptoms subsided by age 13. Boys who experienced accelerated pubertal growth over time displayed elevated symptom levels. Results support the early timing hypothesis for girls and the stressful change hypothesis for boys. Time at assessment is critical when examining boys' pubertal transition. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

为了得到垂直分层大地电导率和雷电回击通道倾斜角度对雷电电磁脉冲场(LEMP)的影响规律,该文利用时域有限差分法对倾斜通道雷电电磁场进行了建模计算。研究结果表明,当观测点位于倾斜回击通道下方时,地表雷电电磁场峰值会随着回击通道倾斜角度的增加而出现明显的上升,同时电磁场的上升沿变得更加陡峭。观测点与地表雷击点之间的水平距离越大,雷电电磁场的峰值时间也就越大。对地表电磁场而言,观测点同侧大地电导率主要影响雷电水平电场和角向磁场的初始峰值,而观测点另一侧大地电导率的变化则主要影响水平电场和角向磁场波尾幅值。对地下电磁场而言,增加埋地深度对垂直电场的衰减作用十分明显,而对水平电场和角向磁场来说影响极小。  相似文献

针对云闪反冲流光的电磁辐射问题,基于偶极子法建立了云闪反冲流光过程的三维电磁场计算模型,研究获得了观测方位角、反冲流光传播速度以及通道弯曲对其地面电磁场计算的影响规律.结果表明:除中间过渡场区以内的地面电场外,观测方位角越大,斜向云闪通道地面电磁场的幅值越小;反冲流光传播速度越大,相应地面电磁场的幅值越大、脉冲宽度越窄;云闪通道弯曲将导致地面电磁场波形出现不同程度的起伏波动,但沿斜向通道主干附近出现的随机弯曲,基本不会影响其地面电磁场波形的整体走势.  相似文献
