衡阳市急救中心服务区域规划的模糊决策

文章针对衡阳市现存具有市级以上急救能力的大型医院现状,采用模糊评价评判的方法对衡阳市急救中心服务区域进行了地区规划;同时给出了一个合理优化的选址方案,该方案克服了传统选址方法的片面性、局限性和计算复杂性,不仅适应于急救模型的选择排序,也可应用于多种可选择方案的排序,使选址问题变得更加合理,科学全面,更加反映客观实际.     

GIS专业信息类课程设置的思考——以钦州学院为例

信息技术对GIS专业学习非常重要,其课程设置对GIS的学习效果产生着重要影响。钦州学院GIS专业现有信息类课程设置存在缺乏完整的课程体系、实践环节薄弱及缺乏系统、新鲜的GIS教材的问题,针对这些问题并结合GIS专业现状,提出了GIS专业信息类课程的设置方案,以提高钦州学院GIS专业信息类课程教育的教学质量和教学效果。     

从藏品到展品，从沉默者到讲述者——科学博物馆藏品向展品的转化模式与传播效果分析

现代科学博物馆与传统珍品收藏所的根本区别之一,即“藏品转化为展品”。对于科学博物馆来说,其展览品质和功能的实现,很大程度上取决于藏品转化为展品的深度和质量。通过理论研究和实践分析,笔者提出“图文转化”“多媒体转化”“机械与机电互动转化”和“叙事场景转化”四种藏品向展品的转化模式,旨在充分激活藏品功能,挖掘出其中的信息内涵并呈现给观众,最终实现展品展陈及博物馆教育的多重价值。     

A nonlinear dynamic macro-element for demand assessment of bridge substructures subjected to ship collision

For the dynamic demand assessment of bridge structures under ship impact loading, it may be prudent to adopt analytical models which permit rapid analysis with reasonable accuracy. Herein, a nonlinear dynamic macro-element is proposed and implemented to quantify the demand of bridge substructures subjected to ship collisions. In the proposed nonlinear macro-element, a combination of an elastic-plastic spring and a dashpot in parallel is employed to describe the mechanical behavior of ship-bows with strain rate effects. Based on the analytical model using the proposed macro-element, a typical substructure under 5000 deadweight tonnage (DWT) ship collision is discussed. Our analyses indicate that the responses of the structure using the nonlinear macro-element agree with the results from the high resolution model, but the efficiency and feasibility of the proposed method increase significantly in practical applications. Furthermore, comparisons between some current design codes (AASHTO, JTGD60-2004, and TB10002.1-2005) and the developed dynamic analysis method suggest that these design codes may be improved, at least to consider the effect of dynamic amplification on structural demand.

Buckling response of offshore pipelines under combined tension, bending, and external pressure

The buckle and collapse of offshore pipeline subjected to combined actions of tension, bending, and external pressure during deepwater installation has drawn a great deal of attention. Extended from the model initially proposed by Kyriakides and his co-workers, a 2D theoretical model which can successfully account for the case of simultaneous tension, bending, and external pressure is further developed. To confirm the accuracy of this theoretical method, numerical simulations are conducted using a 3D finite element model within the framework of ABAQUS. Excellent agreement between the results validates the effectiveness of this theoretical method. The model is then used to study the effects of several important factors such as load path, material properties, and diameter-to-thickness ratio, etc., on buckling behaviors of the pipes. Based upon parametric studies, a few significant conclusions are drawn, which aims to provide the design guidelines for deepwater pipeline with solid theoretical basis.     

长汀民俗舞蹈“高跷扑蝶”的传承与发展

"高跷扑蝶"是流传于长汀民间一项传统的民俗舞蹈。而今,无论在表演形式还是在艺术特征上都没有太大发展,并且受到的当代新兴文化的冲击。"高跷扑蝶"这个民俗舞蹈跟其他民俗文化一样,走向濒危。为了保护这一传统民俗舞蹈,文章将从长汀民俗舞蹈"高跷扑蝶"的历史由来、该民俗舞蹈的传承现状、发展的办法与措施的问题进行阐述。     

西部欠发达地区学前教育发展现状与对策——以贵州省为例

近年来,在政府的大力支持和全省人民的共同努力下,贵州省的学前教育事业得到了健康、快速的发展,社会各界开始重视学前教育,管理逐步规范,办学体制不断得到完善。但在发展过程中也存在一定的困难和问题,如管理制度不够健全、发展不平衡、没有稳定的经费保障、师资欠缺等。因此,结合国家中长期教育发展规划纲要关于学前教育的相关规定,探讨贵州省学前教育发展的目标与措施显得相当重要。
