摘要：According to the holistic approach, factors relevant for the promotion of a desire of change should beaccommodated in a synchronized manner. Need to implement this approach is the topic of this paper. Putdifferently, the topic of research has to do with desired change through implementation of holistic approach.

摘要：Recently service orientation is becoming a mainstream approach for building large scale software systems. A key requirement in service-oriented design is the dependability of service. It stipulates that the behavior of services is controllable. Formal models can aid in constructing software in a dependable manner. They can describe ser- vices precisely and compose them together consistently. This paper presents a strategy for service realization based on a novel layered formal model. When a service is provided or required via internet, the semantic consistency becomes critical issue, Our architecture tackles the issue by proposing a novel scheme： defining contract of a service to keep semantic information. Although service-oriented design is our prime target, the contract models, to a large extent, are independent of the framework of design and therefore applicable to large scale software design in general.

摘要：This article, which utilizes the quantitative social-background approach, sets as its objective to empirically discern correlations between the behavior of the Jewish political elite, embodied in the Jewish Agency for Palestine in the period from 1921 to 1948, and the following social-background variables： age, foreign travel, occupation as a path to political power, regional affiliation, ideology, and political opportunity, of the JAE membership. Diversity of the social-background variables and, particularly, the multitude of languages they knew, explain, to a considerable extent, firstly, the wide variety of their social, political and economic views, and, secondly, the elite＇s resort to direct contact with Western governments and peoples in communicating and promoting their political ideology, thus facilitating the realization of the Zionist project.

摘要：For the users＇ convenience of accessing the AGRIS resources quickly and using them fully, the paper decomposes the structure of AGRIS Search net, analyzes the users＇ requirement met for conducting a bilingual （ZH/EN） retrieval, the system function extensions based on AGRIS English retrieval system and the key issues which the core function module should resolve. Derived by the application requirement, the paper also puts forward to a bilingual retrieval model on the basis of CAT/AGROVOC mapping, designs and realizes the ZH/EN bilingual retrieval prototype system.

摘要：　　钢铁是长期以来对社会和发展起主要作用的基础材料.基础结构、运输、集装箱、电力生产和输送、商品制作甚至金融系统都以不同形式在使用着钢铁产品.近数十年已有几个预言,指出钢铁作为社会的主要材料已快结束.替代材料,如合成材料、塑料、陶瓷和玻璃,已发展有新的性能,在许多应用方面可以取代钢铁.但同一时间,优秀的钢铁产品设计扩大了其应用范围,涉及钢铁产品应用开发的投资在继续扩大.因此,尽管有相反的预言,但在近期的将来,没有理由去期待钢铁应用会衰落下去.　　……

摘要：构造了层次化的SOA模型,并提出了将服务使用层与服务实现层分层处理的策略.建立了基于服务的构件模型来实现SOA中的服务,使用接口来描述服务的语法,契约来描述服务的语义,并用卫式设计来模服务的行为.将接口作为结合构件技术与面向服务架构的关键.用实例说明了如何使用这种方法来实现面向服务的设计.此工作为利用构件技术解决面向服务架构中的服务实现问题奠定了基础.
