    Responses of 150 IEEE members to a telephone survey sponsored by Nihon Keizai Shimbun, a Japanese counterpart to The Wall Street Journal, are reported. The interviews were conducted by the Gallup Organization Incorporated. The respondents-50 each from government, industrial, and academic facilities-answered more than two dozen questions, some of which were suggested by the IEEE, regarding the rela...

    The ergonomic aspects of the engineering workstation environment are addressed. The controversy surrounding the effect of extremely low-frequency (ELF) magnetic fields is examined. Guidelines are given for positioning monitors to keep exposure levels below 0.2 mu T. Suggestions are also given for selecting and positioning the monitor to fend off eye, neck, or back strain and for proper chair and d... View full abstract»

    The process employed by a group of workstation designers in creating a prototype for a high-performance, low-cost workstation is described. The design team moved an existing architecture-the precision-architecture, reduced-instruction-set computer (PA-RISC) design-into the realm of a low-cost desktop computer. The goal was to make a PA-RISC implementation suitable for a high-performance single-use... View full abstract»

    Japan's plans to reprocess fuel and create a waste depository in Japan and to add two plants a year for 20 yr to meet future energy needs are discussed. A recent accident in which an aging pressurized-water reactor sprang a leak in its primary cooling system and its potential impact on these plans are examined. The status of Japan's nuclear industry and technology is discussed, focusing on safety ... View full abstract»
