This work, in synthesis, is about the exercise of good corporate management practice. The systematic nature of administration, alignment, strategy and skills in the metal mining sector in peru, influence of the Resource and Capacity development theory. We also deal with the value chain, competitive advantages, strategies and skills in the metal mining activity and mining strata. From the development of these points, we set up as conclusions that all formal, legal or illegal strata coexist somehow because the legal ones can export all production. On the other hand, it is required a strategy, promotion, planning and specialized professional leadership in this industry. At the same time, it is required that the government support all this effort and the centers of technical and vocational training in geology, mining, metallurgy, chemistry and related competences define and design formation ...

This article treats the following problem How can we reduce the noise emission in a room?; to answer to this question it has been considered to absorbent materials like Glass Wool and Nappe Textile by mean a construction of a board acoustic prototype they put under an experiment following the instructions of the UNE-EN 20354 norm and being obtained satisfactory results to both materials, but in especial to the Glass Wool.
