IP资源管理利器

基于TCP/IP的互联网规模在不断的发展中变得越来越庞大,这是ARPANET的发起者所始料不及的。虽然通过私有子网的划分和网络地址转换可以解决IP地址资源缺乏的问题,但是在节点增多,结构变得更加复杂以后,逐渐增多的IP资源的管理又成了一个问题。所以,我们仍然需要一个有效的方法去管理IP资源。     

浅谈电气二次及继电保护

随着电气设备在人们日常生活中使用次数的逐渐增多，电气设备所引发的事故次数也在逐渐的增多，在电气设备的使用中如果不进行相应的保护措施，就非常容易引起事故，威胁人们的生命财产安全，因此，电气设备在设计生产时，通常都会按照继电保护装置，以保证电气设备的正常运行，本文主要针对电气设备二次及继电保护进行简要的讨论，希望继电保护装置在电气设备的使用中发挥更大的作用。

IT in teacher training in France

Abstract To understand what is going on in France at the moment in the domain of computers and related communication technologies in teacher training, there are two major developments that have to be kept in mind. Firstly, the ways of becoming a teacher in France underwent major changes in 1991. It is therefore too early to come to general conclusions about the effects of this reform in the field of new information technologies. Secondly, French IT in schools policy has shifted from a large-scale centralized equipment operation, which provided microcomputers in each school from 1985 to 1987, to a more regional management of equipment funding, with less national piloting in the field. This paper describes what happened during the previous period and what is taking place now. With matters still evolving the paper represents a snapshot rather than an exhaustive survey; such a survey remains to be done.     

Teacher education in IT in Germany

Abstract In 1988 the eleven West-German Kultusminister , with responsibility for the school systems in their respective Bundeslaender , reached agreement with the Federal Ministry of Education and Science on the broad concept of 'Information and Communications Technology', ITG. After four years of discussion it was agreed that ITG should be introduced into the secondary level of the general schools. In spite of strong disagreements about the ways and speed of implementation, and after several years of experiments, important parts of the concept have become a reality in practically all of the old Bundeslaender. While acknowledging the complexity of the German educational system the paper attempts to outline the development of the concept of Information and Communications Technology and its consequences in teacher education. The development in the eastern part of Germany, the former GDR, has been completely different to that in the western part and this is also commented upon in the paper.     

IT in teacher education in Scotland

Abstract This paper outlines the consensual approach to the formulation of curriculum policy in general, and in relation to information technology (IT) in particular, in Scotland. It outlines the approaches to IT that have emerged as a result. These are founded on the premises that all children should develop knowledge and understanding about IT and skills in using IT; that IT should influence both content and delivery of the curriculum; and that IT (computing studies in Scotland) should be an elective for secondary school pupils. Against this background, the paper describes the evolution of policy and practice relating to IT in teacher education. It appraises the strategies which institutes are using for developing the professional skills necessary to deliver IT in the Scottish curriculum. It notes significant progress but highlights the need to develop strategies which integrate IT more deeply with other professional studies so that student teachers develop deeper, more reflective approaches to IT.

Recent developments in ergonomics in China

Ergonomic thought and practice were introduced in ancient China in relation to modern developments in Chinese ergonomics. Despite the ten-year interruption of the 'cultural revolution’ in the late 1960s and 1970s, ergonomics has made great progress in China in the last decade. In this paper some general developments in recent ergonomics’ teaching and in professional organizations are described. Four major areas of ergonomics research are illustrated: (1) Visual displays and signal design; (2) Human-computer interface with Chinese computers; (3) Cognitive strategies and decision support; (4) Mental workload and occupational stress. The main characteristics of Chinese ergonomics are discussed and new directions are highlighted, based on recent developments and progress.
