It has been estimated that consumers waste $500 million a year on medical quackery and another $500 million annually on some "health foods" which have no beneficial effect. Unnecessary deaths, injuries and financial loss can be expected to continue unti1 the law requires adequate testing for safety and efficacy of products and devices before they are made available to consumers.

In this paper an approach to design information systems for traceability is proposed. The paper applies gozinto graph modelling for traceability of the goods flow. A gozinto graph represents a graphical listing of raw materials, parts, intermediates and subassemblies, which a process transforms into an end product, through a sequence of operations. Next, the graphical listing has been translate...

The aim of this study was to assess to which extent the modernisation of an anode plant had reduced occupational chemical health hazards for jobs with the highest potential of exposure. Periodical measurements of dust and gases were performed at the same workplaces using the same methods, before and after modernisation. These measurements were compared with the recommended standards. Before mod...

Design for Manufacture and Assembly (DFMA) technique has been utilized extensively in industry field these days. This paper is a detailed review which will discuss the development history of DFMA, compare some other “DFMA-like” theories, and good stories about the successful implementations of DFMA in real-word product design. 1. DFMA and its development history 1.1 Traditional design paradigm ...

Nota.-El presente artículo fue enviado por el autor expresamente para el presente número de la Revista Virtual de REDESMA. Abstract Sustainability has become a key concept in development theory, yet a clear and well-organized central body of accepted theory supporting it does not exist. Sustainability goals and issues are being addressed with traditional sustainable development tools and strate...

This paper discusses the use of excimer lasers in the manufacture of microelectromechanical devices and systems. With emphasis on two application areas: laser micromachining of polymer masters for replication in metal by electroplating (Laser-LIGA), and laser-assisted manipulation of microparts for hybrid assembly. As a master fabrication method, laser micromachining offers advantages over conv...

The present journal recently stated in the call for a special issue on social sustainability, ―[t]hough sustainable development is said to rest on ̳three pillars‘, one of these—social sustainability—has received significantly less attention than its bio-physical environmental and economic counterparts‖. The current issue promises to engage the concepts of ―development sustainability‖, ―bridge s...
