高校体育教学改革对终身体育的影响

终身体育是指一个人终身进行身体锻炼和接受体育指导及教育.高校体育是为实施终身体育打基础的最重要的阶段,因此高校的体育教学一定要围绕着“终身体育”和“健康第一”这一宗旨进行改革.本文以终身体育理论的提出、高校体育在终身体育中的地位为基础,着重探讨了高校体育教学改革的新举措对终身体育的影响：重视选项课程,取消基础课程;重视个体差异,学会以人为本;重视导向功能,培养积极分子;重视全程教育,加强课外环节.

指导发现式教学在篮球普修课教学中运用的实验研究

通过实验的方法,将"发现"式的学习理论应用于教学实践。实验表明:实验班的学生在篮球专项技术、操作思维能力、身体素质及运用篮球知识和技术解决问题的能力等方面明显高于对照班。"指导式发现教学"可使初学者尽快地掌握正确的技术动作,缩短技能形成所需要的时间;可使学生在学习技术动作的同时,深入系统地掌握理论知识;可培养学生运用知识进行观察、分析、判断能力,养成主动的学习习惯。     

基于真实IPv6地址的P2P邮件系统研究与实现

电子邮件一直是互联网最重要的应用之一, 但现有基于SMTP协议和客户/服务器模式的电子邮件系统采用类似路由器的转发机制,由于服务器无法验证最初发送者的身份或源地址的真实性,导致垃圾邮件泛滥,而现有基于内容分析的过滤机制误判率高,经常导致邮件丢失.本文研究基于真实IPv6地址访问的P2P电子邮件体系结构,提出了基于真实IPv6地址的发信人身份认证技术,设计实现了基于真实IPv6地址访问的P2P电子邮件系统,实现了对发信人源地址的认证与追踪,使得假冒源地址的垃圾邮件根本无法发出.

Simulating FAS-induced apoptosis by using P systems

In contrast to differential equations, P systems are an unconventional model of computation which takes into consideration the discrete character of the quantity of components and the inherent randomness that exists in biological phenomena. The key feature of P systems is their compartmentalised structure which represents the heterogeneity of the structural organisation of the cells, and where one can take into account the role played by membranes in the functioning of the system, for example signalling at the cell surface, selective uptake of substances from the media, diffusion across different compartments, etc. We show here that P systems can be a reliable tool for Systems Biology and could even outperform in some cases the current simulation techniques based on differential equations. We will also use a strategy based on the well known Gillespie algorithm but running on more than one compartment called Multi-compartmental Gillespie Algorithm.     

P systems with array objects and array rewriting rules

Array P systems were introduced by Paun Gh. which is linking the two areas of membrane computing and picture grammars. Puzzle grammars were introduced by us for generating connected picture arrays in the two-dimensional plane, motivated by the problem of tiling the plane. On the other hand, incorporating into arrays the developmental type of generation used in the well-known biologically motivated L systems, Siromoney and Siromoney proposed a very general rectangular array generating model, called extended controlled tabled L array system (ECTLAS). In this paper we introduce two variations of the array P system, called BPG array P system and parallel array P system. The former has in the regions array objects and basic puzzle grammar rules (BPG), which are a specific kind of puzzle grammar rules. In the latter, the regions have rectangular array objects and tables of context-free rules. We examine these two types of P systems for their array generative power.
