In the last two decades (70 and 80) there took place an intensive controversy in the field of Industrial and Work Sociology. There the topic of the study object of this scientific discipline is again discussed. This controversy, however, has a relatively different sense in comparison with the one that existed in early 60ies. The more recent one followed the increasing number of possibilities of electronical equipment for data processing at the same time its price is decreasing. In this article we try to give knowledge of the main elements that take part in such debate. It is also important to present the international character of the research developed in association with this discussion. It evolves a plurality of research teams that present, compare and synthesize the results of empirical studies that are applied for a wide variety of countries.

The design of jobs is defined and its different implications. These aspects must be taken into consideration when applied to new automated systems, once it can occur workers in-adaptations to certain type of activity and tasks. Other concepts that emerge from this are the mental workload, stress, work accidents, shift work, or the physical environment that can reveal to become determinant in the process of job design. That means also the organizational design. In this sense, the manufacturing, organizational and individual dimensions, are the most meaningful in the mentioned process of organizational design. Are analyzed different application cases of robotized systems and their social effects, mostly those that are related to the dimensions of working conditions. Are particularly analyzed the new risk situations that occur with the use of robotic systems. One concludes on the need to take into consideration qualitative variables in the definition and design of robotic cells, jobs and production systems. This consideration influences directly in the labor productivity, in such way that the development of these methodologies of analysis can be considered as integrating the processes of technological innovation in manufacturing.

This paper deals with a new model and structure able to tailor defects in pin devices. The model assumes the usual density of states profile, including donor and acceptor like states inside the mobility gap and has the capability to simulate the transient and steady state device behavior. The new structure is based in two interfacial defectous layers, located at the junctions, acting as "gettering" centers to tailor the defects. The role of the interlayer and its thickness on device performances will be also discussed. © 1993.

A study using a primary Cs’ beam to carry out positive SIMS on conductive samples is presented. The energy distribution of positive secondary ions was measured and the sputter yield, S’ was calculated for several elements, The significantly different energetic behavior found between the secondary cesium ions and those ejected from the target will be discussed. Finally, the best conditions to perform positive SIMS with such a primary beam will be described.

Industrial rationalization represents a decisive moment of the strategic development of business activities in the last few years. In this sense, it is also a theoretical challenge to Industrial Sociology, since the dimensions, both technical and social, of that rationalization can be underlined. The analysis of the better-known different patterns of rationalization allows us a further knowledge of the main strategies for industrial modernization. Accordingly, this paper presents some results deriving from the application of those strategies. Finally, this paper gives a particular attention to the more recent tendencies of development of integrated systems of production, particularly of those focusing upon the social and organizational aspects of industrial rationalization.
