Regression (PLS-R) are the most applied methods in waste management. PCA was used to find hidden data structures, groupings and interrelationships of data. In most cases PLS-R was applied to predict parameters using new analytical instruments that allow faster and

In general it can be stated that multivariate data analysis was successfully applied in all experiments. Several authors compared different multivariate methods to determine which one provided the best results. Depending on the data set and the question to be answered

Humans has constantly changed the environment, requiring the design and the development of new technologies and these, in turn, eventually modify the man, his attitudes and society as a whole. This demand for innovations may be the result of well-intentioned ideas for a better life, or they may appear at the intention of ostentation of fetishes or even to perpetuate conditions of inequalities and hegemonic power [1-3]. Thus, different forms of relationship between society and technology are set out in pursuit of progress. A growing concern to integrate science and technology (S&T) for the welfare of society gets increasingly more space, especially since last century, when we felt a strong mixture of hope and fear on seeing the concretization of man's dream to conquer space at the same time in which the world feared for

In an attempt to discuss the results of progress, much has been said about the formation of citizens conscious and able to take decisions involving the welfare of the community, at the

To better understand the scene briefly discussed here, this work propose the creation and analysis of indicators of how society can influence people in their relationships with technology, reflecting their conceptions or their attitudes towards the technological development. The understanding of these relationships can generate foundations for many discussions, especially for the support of future questions of how public policies for science, technology and education will allow a more effective and active participation by the citizens
