The atmospheric contamination caused by the emission of dust and gases represents the main environmental impact related to the plants that benefit aggregates for construction. During operation, there are several operations that lead to the greatest generation of dust, such as crushers (primary and secondary), screens for the classification of materials, transfer of material from or to conveyor belts (continuous transfer) and transfer of material from or to hoppers and trucks (discrete transfer). The objective of this paper was to show a procedure to quantitatively estimate the amounts of dust that are generated, taking as a basis for calculation then emission factors contained in document AP-42 of the US Environmental Protection Agency. As a result of the calculation, it was obtained that the total amount of sedimentable dust emitted per ton of material processed is about 51 g, of which 19 g correspond to the fraction with diameter less than 10 m. If it is taken into account that the volume of raw material processed in a day is equal to about 700 t, the total amount of dust produced would be equal to 35,7 kg, which would pass almost entirely to the outside, as this plant does not have devices and systems to protect against dust.

The process of professionalization of teachers is currently an issue of great national and international importance, which is debated and studied by researchers from various edges. This article aims to implement a strategy to develop the process of professionalization, in favor of performance modes competent, qualified teachers in Technical and Vocational Education, determining components and contradictions used as general method materialistic dialectic, allowing the study of the object as a process systematization of theoretical considerations on these concepts are discussed in the contemporary scientific community, from the document review, are elements in the construction of contextualized definitions of both terms is sustained, and can contribute to the design of new takes professionalization actions, in line with current educational and social requirements.

The present work developed in the Company of Attention to Teams located in the km 31/2 highway to Viñales, in the municipality Pinegrove of the River, county Pinar del Río of the River, Cuba; had as main objective to implement a guide I diagnose for the environmental administration; where they were analyzed the reduction of the negative environmental impacts, fundamentally those associated to the energy consumption, natural resources and generation of pollutants. The methodology used for the case study object, was through the empiric methods, everything it starting from the participant observation and the surveys; leaving for it of the methodology emitted by the (CITMA, 2011). as a result of the same one the existence of possibilities was demonstrated of reducing the residual pollutants and the decrease of the noise, with it is achieved it to increase the efficiency in the adoption of technician-organizational measures of character; also, the important paper was identified that plays in those purposes the direct participation of the operatives and intermediate bosses that work in the key positions. The carried out evaluation evidenced that the control and the administration of the Division, they derived in a strategy with premeditation directed to minimize the environmental impacts that are generated on the other hand. The investigation throws that all the impacts generated by the different areas of key results give a negative character; all are moderate except for the contamination of waters and floors for accidental shedding.

In order to evaluate the effectiveness of information security management and the risks associated with its use, in computer networks, at the Santa Elena Peninsula State University, the implementation of a model that establishes the goals to be achieved to advance was proposed, through the different levels that make up the rating scale. The model is formalized with the main standards, recommendations and existing regulations, both at an international and national level, on information security management and offers a comprehensive vision of information security controls, considering all the automated controls and not automatable and defines the actions to be carried out in each of the cases. The model does not constitute a new proposal of controls and management processes, but rather provides an automation, integration and synthesis approach to existing proposals, to reduce the complexity of management and increase the effectiveness of information security controls in computer networks.
