Experimental studies conducted primarily on non-human primates have begun to address the anatomical and neurochemical correlates of working memory. There is an associated growing body of experimental literature investigating whether modulating key neurotransmitters can facilitate working memory in humans. This paper reviews evidence that acute modulation of dopamine in particular, but also nora...

Working memory is the memory system that allows us to briefly keep information active, often so we can operate on it. Studies with rhesus monkeys first established that this system is partly mediated by neural mechanisms in the prefrontal cortex. Recently, there has been a substantial effort to study the neural bases of working memory in humans, using neuroimaging techniques such as positron em...

Even in an advanced factory, human workers or craftsmen have been required to achieve highly flexible and skillful production. This paper introduces the management architecture for human oriented production systems. The proposed architecture includes two technologies; one is the communication network in the factory using the active database system, and the other is the dynamic scheduling method...

Cold protective clothing was studied in 2 European Union projects. The objectives were (a) to examine different insulation calculation methods as measured on a manikin (serial or parallel), for the prediction of cold stress (IREQ); (b) to consider the effects of cold protective clothing on metabolic rate; (c) to evaluate the movement and wind correction of clothing insulation values. Tests were...
