Many studies show that rural left-behind children and “un-left-children” have significant differences such as psychology, behaviors and learning. In some rural areas, left-behind children have high dropout rate. The article surveyed rural left-children present situation of alienation in Henan province and found out the alienation of left-behind children is stronger than un-left-behind children, mainly reflected in normlessness, powerlessness and isolation. According to the situation, selecting subject for group counsel and the effect is significant. The result shows group counseling is a successful way and favored by students. It is worth promoting. Finally, put forward suggestions. © Sila Science. All Rights Reserved.

In the present work, the structural and dynamical aspects of the solubilization process of pyrene within a sodium dodecyl sulfate micelle were studied using molecular dynamics simulations. Our results showed that free pyrene as the fluorescence probe can be spontaneously solubilized into the micelle and prefers to be located in the hydrophobic core region. As the local concentration of pyrene increased, two molecular probes could enter into the core hydrophobic region and the excited dimer of pyrene molecules was formed, showing a stacking mode of π-π conjugation. Since the π-π stacking interaction between the two pyrene molecules was very weak, formation of the excimer was a dynamic process with the two pyrene molecules alternately separating and associating with each other. In this case, the two pyrene molecules were found to be mainly distributed in the palisade layer of the micelle due to the balance between the weak π-π stacking interaction and the hydrophobic interaction of probe molecules with the surfactant tails. © 2012 American Chemical Society.

Firstly, the paper made a contrast between the current domestic and international research condition, and introduced the basic concept of fault injection and distributed system. secondly, it discussed the classification and requirements of fault injection. There are mainly three types of distributed fault, namely the memory fault, CPU fault and correspondence fault. Besides, it discussed the method of distributed software fault injection about DOCTOR and illustrated the comprehensive structure and its respective parts of DOCTOR in detail. Thirdly, it reached a conclusion about the fault model of distributed system of fault injection and its realization method. © 2010 IEEE.

With the wide application of geographic information system technology in water conservancy projects, many projects have established GIS database for digital watershed which enables to use the current information resources for pre-processing and to modeling of the finite element. In this paper, that pre-processing system of the finite element based on GIS is constructed in combination with the basic theory of the finite element, GIS technology, 3D graphics development technology and CAE technology, the methods and the key technologies of the implementation of the finite element, including the generation method, commonly used unit and shape function, load and boundary conditions of FE-Mesh are discussed in detail and the problems of achieving 3-D graphic and image design, interaction between the finite element model and the GIS data and communication interface of CAD and ABAQUS in the system were discussed. © 2014 CAFET-INNOVA TECHNICAL SOCIETY.

Cloud computer technology is one of current hot areas of the development of the information technology, and the data storage service based on the cloud is developing rapidly, which makes more and more enterprises and individuals enjoy the efficiency, convenience as well as low cost supplied by cloud storage. However, at the same time, the security problem of cloud storage arouses users' attention. This paper firstly expounds the basic information and system of cloud storage, then analyses the status quo of the development of cloud storage, and finally offers some preventive strategies based on cloud storage security. © (2014) Trans Tech Publications, Switzerland.
