The History Change of Wushu Value Orientation and Modern Needs
以不同时期的社会需要对武术价值的影响为研究对象,分析武术价值变化的影响因素和规律,提出武术价值在不同历史时期发展中的变动不是杂乱无章的,而是有着内在的规律性,其主导因素在于社会价值观对武术发展的导向作用,当今社会核心价值观决定了武术发展的现代化需要。Taking the impact of different period of the society needs on Wushu value as the research object,this paper analyzes the influential factors and regularities of the variation of Wushu value.It puts forwards that the development of wushu value changes in different historical periods is not messy, but exists the inherent regularity.The dominant factor is the social values guiding role to the development of Wushu.Modern core values determine modern society needs of Wushu development

A Join and Aggregate Algorithm for Complex Multi-Dimensional Hierarchies
由于数据仓库中存储着不同粒度、容量巨大的数据记录 ,所以如何有效地执行联机分析处理 (OLAP)查询操作 ,特别是连接和聚集操作 ,便成为数据仓库领域的核心问题之一 为此 ,提出了一种降低连接和聚集操作的新算法 (joinandaggregationbasedonthecomplexmulti dimensionalhierarchies,JACMDH) 算法充分考虑了复杂多维层次的特点 ,在原有的位图连接索引 (bitmapjoinindex)的基础上 ,采用层次联合代理 (hierarchycombinedsurrogate)和预先分组排序的方法 ,使得复杂的多维层次上的连接和聚集操作转化成事实表上的区域查询 ,从而在处理多维层次聚集的同时 ,提高了连接和聚集的效率 算法性能分析和实验数据表明 ,JACMDH算法和目前流行的算法相比 ,其性能有显著的提高Enormous volume of data reside in data warehouse, so it is important to process efficiently expensive queries including join and aggregate operation. In this paper, a new method (JACMDH algorithm) is proposed for processing time-consuming join and aggregate operation. This algorithm takes into consideration the characteristics of the complex multi-dimensional hierarchies and adopts hierarchy combined surrogate/pre-grouping and pre-sorting on the basis of bitmap join index. It improves the join and aggregate efficiency by translating join and aggregate operation of complex multi-dimensional hierarchies into range queries of fact table. The performance analysis and the experimental result, show that the performance of JACMDH algorithm can be improved dramatically, compared with current method for aggregation query evaluation.福建省自然基金项目 (A0 3 10 0 0 8) ;; 福建省高新技术研究开放计划重点基金项目 ( 2 0 0 3H0 43
LSNCCP:A Clustering Algorithm Based on the Largest Set of Not-Covered Core Points
聚类在数据挖掘、模式识别等许多领域有着重要的应用 提出了一种新颖的聚类算法 :一种基于最大不相含核心点集的聚类算法LSNCCP(aclusteringalgorithmbasedonthelargestsetofnot coveredcorepoints) 在密度定义的基础上 ,考察核心点之间的距离关系 ,定义相含、相交、相离这 3种核心点之间的关系 ,最后找出一个最大不相含核心点集 ,在此基础上进行聚类 ,并且找到解决丢失点问题的快速方法 该最大不相含核心点集只是全部核心点集合的一个很小的子集 ,因此有效地缩减了同类算法中搜寻核心点的时间 理论和实验上证明了这种算法的可行性和优越性Clustering is an important application area for many fields including data mining, pattern recognition, etc. In this paper, a novel clustering algorithm LSNCCP(a clustering algorithm based on the largest set of not-covered core points) is proposed. On the basis of the definition of density, the distance between the core points is discussed. And then, the three essential distance relation: covered core points, intersectant core points, and separate core points. Finally, the largest set of not-covered core points is found and based on the set the data can cluster very well. Because the largest set of not-covered core points is a lesser subset of the all core points, the new algorithm cuts short the time of searching all core points in the similar algorithms. The feasibility and the advantage or the new algorithm are proved in theory and experiment.福建省自然科学基金项目 (A0 3 10 0 0 8) ;; 福建省高新技术研究开放计划重点项目 (2 0 0 3H0 43
