目的提高患儿剥夺睡眠脑电图检查的依从性。方法对214例接受剥夺睡眠脑电图检查的患儿(对照组)采用常规健康教育方法,于检查后采用自制问卷对其进行剥夺睡眠脑电图依从性影响因素调查。根据调查结果,制订相应的健康教育措施并实施于381例患儿(观察组)。比较两组患儿对剥夺睡眠的依从性。结果监护人或患儿对剥夺睡眠重要性的认识、对检查过程的理解程度、过去剥夺睡眠脑电图经验、病史长短、担心发作、患儿的适应性及智力是影响患儿对剥夺睡眠依从性的主要因素(P<0.05,P<0.01)。观察组剥夺睡眠依从性显著高于对照组(P<0.01)。结论探讨影响患儿剥夺睡眠脑电图依从性的因素并实施针对性的健康教育,能提高剥夺睡眠脑电图患儿的依从性。

As a result of the interaction between hydrodynamics and the effects of gravity,riverbank collapse is a common occurrence in the desert reach of the upper Yellow River(also called as Ningxia-Mongolia Inner reach),of which the riverbank may be divided into three types such as sandy riverbank in the widevalley desert reach,silt-deposition riverbank on the fluvial plain and silt-sandy *** characteristics of both typical riverbank collapse and the particle size distributions(PSDs) for collapsed riverbanks of sandy,silt-deposition,and silt-sandy types were determined from analysis of data obtained from the field *** was found that particles from the silt-deposition riverbank had the smallest median size and those from the sandy riverbank the largest,with those from the silt-sandy riverbank being intermediate in *** PSDs of the sandy and silt-deposition riverbanks exhibited double-peaked and single-peaked structures,respectively,while those of the silt-sandy riverbank exhibited multiple ***,the corresponding to three kinds of riverbank collapse mechanisms were revealed,These results are significant with regard both to the understanding of river dynamics and to the planning of river harnessing projects.

In this survey on extremum problems of Laplacian-Dirichlet eigenvalues of Euclidian domains, the author briefly presents some relevant classical results and recent progress. The main goal is to describe the well-known conjecture due to Polya, its connections to Weyl's asymptotic formula for eigenvalues and shape optimizations. Many related open problems and some preliminary results are also discussed.

In this paper,we study large m asymptotics of the l 1 minimal m-partition problem for the Dirichlet *** any smooth domainΩ⊂R^(n)such that|Ω|=1,we prove that the limit lim_(m→∞)l^(1)_(m)(Ω)=c 0 exists,and the constant c 0 is independent of the shape ofΩ.Here,l^(1)_(m)(Ω)denotes the minimal value of the normalized sum of the first Laplacian eigenvalues for any m-partition ofΩ.

This is in the sequel of authors’ paper [Lin, F. H., Pan, X. B. and Wang, C. Y.,Phase transition for potentials of high dimensional wells, Comm. Pure Appl. Math., 65(6),2012, 833–888] in which the authors had set up a program to verify rigorously some formal statements associated with the multiple component phase transitions with higher dimensional wells. The main goal here is to establish a regularity theory for minimizing maps with a rather non-standard boundary condition at the sharp interface of the *** authors also present a proof, under simplified geometric assumptions, of existence of local smooth gradient flows under such constraints on interfaces which are in the motion by the mean-curvature. In a forthcoming paper, a general theory for such gradient flows and its relation to Keller-Rubinstein-Sternberg’s work(in 1989) on the fast reaction, slow diffusion and motion by the mean curvature would be addressed.
