Sharing, management and on- demand allocation of network resources are particularly important in Cloud computing. Ho- wever, nearly all-current available cloud com- puting platforms are either proprietary or their software infrastructure is invisible to the rese- arch community except for a few open-source platforms. For universities and research insti- tutes, more open and testable experimental plat- forms are needed in a lab-level with PCs. In this paper, a platform of infrastructure resou- rce sharing system （Platform as a Service （PaaS）） is developed in virtual Cloud comput- hug environment. Its architecture, core modules, main functions, design and operational envir- onment and applications are introduced in de- tail. It has good expandability and can impr- ove resource sharing and utilization and is app- lied to regular computer science teaching and research process.展开更多

Based on their study and field practice, CNIS proposes that different types of programs have different aspects of strategic value for the standardization of academic and standard development institutions.

By reviewing the literature of CALL in China and abroad, this article holds the view that in China where the educational resources are insufficient and unevenly distributed, the use of CALL should confirm and expand ESL/EFL theories to the utmost; the research of CALL should focus more on learning or learner, especially on learning strategy in CALL environment; to have a better understanding of the potential and functions of CALL in foreign language instruction, the research of CALL should cover all aspects of language learning.展开更多

To solve this task, special youth programs are developed, various discounts are provided for young researchers＇ participation in IFToMM congresses and conferences. A new progressive type of such an activity is organization of Student International Olympiads （SIO） on Mechanism and Machine Science （MMS） which can be considered a new advantageous form of MMS study. The paper describes experiences of organization and holding the first SIO MMS, which took place on April 19-21,2011 in Izhevsk （Russia） at Izhevsk State Technical University.展开更多

Combining with the practice of HRM construction in Langfang Teachers University, based on the introduction about the necessity of construction of practice teaching system, the construction content, guarantee measures, and implementation effect of practice teaching system for the cultivation of applied talents of HRM are out forward in this paper, which is in favor of the cultivation of applied talents of HRM.展开更多

Methods： The study was conducted fromAugust 2010 to December 2011 and cases were selected from the out- patient department of Postgraduate Institute of Medical Education and Research, India. The patients were in the age group of 30 to 50 years. All patients were operated via both anterior and posterior approaches. Results： During the immediate postoperative period, five （83.33%） patients had normal neurological status. One （16.67%） patient who had C5-C6 subluxation developed neu- rological deficit with sensory loss below C6 level and motor power of 2/5 in the lower limb and 3/5 in the upper limb below C6 level. Conclusion： There is no role of skull traction in ne- glected distractive flexion injuries to cervical spine delayed for more than 3 weeks. Posterior followed by anterior ap- proach saves much time. If both approaches are to be done in the same sitting, there is no need for instrumentation posteriorly. But if staged procedure is planed, posterior sta- bilization is recommended, as there is a risk of deterioration in neurological status.展开更多
