医院电话号码管理系统的开发与应用

随着医院规模的不断扩大,科室越来越多,随之带来的问题是科室电话号码增多,电话簿更新滞后,查找科室电话号码困难。这里用PB与SQL Server2000开发了C/S架构的电话号码查询软件,为电话班开发了电话号码管理系统,这样不仅方便了电话班对于电话号码的管理,保证了医院其它科室迅速获得最新、准确的电话号码信息,也实现了无纸化办公。

Further issues in forecasting primary energy consumption

The series of papers by Marchetti [8, 9, 10] and Graham and Senge [4] (published in this journal between 1977 and 1980) represents a useful alternative approach to the problems of energy demand forecasting and primary energy substitution. The learning system approach seems a most appropriate investigative framework, given the aggregated treatment of the energy supply-demand system. It is also interesting for its attempt to establish a link between the structure of the primary energy markets and the 50–60 year cycles of basic innovations.This paper seeks to illustrate further conclusions from the reported research findings, by considering additional energetic criteria. These additional criteria—energy concentration (or quality) and energy accessibility—appear to reinforce the linkage between innovation waves and primary energy substitution patterns, though we modify the interpretation placed on this connection. Furthermore, the additional criteria lead to alternative conclusions about future energy supply, namely that previously discarded energy sources may be revisited and may retain some of their earlier market share.

Learning curves for new products

A recent article addressing the extrapolation of learning curves fails to point out that the resulting learning curve is not, in general, a straight line but sharply alters its shape at high cumulative outputs.

聚丁烯管材投资项目节能减排评价——以某聚丁烯管材投资项目为例

为加强固定资产投资项目节能管理,促进科学合理利用能源,从源头上杜绝能源浪费,提高能源利用效率、降低碳排放,根据节能法规、标准,选择评价模型,以我国某聚丁烯管材投资项目为例,评价该项目的能源利用是否科学合理,结果显示该项目的年单位产品产量综合能耗为0.44tce/t;项目年综合节能量为589.92tce/t;定比节能率为16%;减少CO2排放量1 474.8吨;与国内同行业单位产品能源消耗比较,该项目处于国内领先水平,但仍有拓展空间,进而提出具体的节能减排建议。     

Sources of Competitive Rivalry in Japan

The fact of the Japanese competitive success on a world scale is well established and we have been offered many reasons for that success. But we know much less about their competitiveness on their domestic markets. And we know even less of the underlying sources of their competitive behavior. Nigel Campbell has studied many facets of Japanese life—the history and culture, the geography and economic structure, the present-day patterns of thinking—and draws for us the structure of the rivalry that we see expressed in global competition. His article is a useful background for any manager seeking a competitive advantage.
