The present work prior to obtaining the title of Master in Occupational Health and Safety whose objective is to evaluate the level of academic stress of the Pre-graduate students of the Faculty of Chemical Sciences of the University of Cuenca to propose preventive measures for the students of this Faculty the study was conducted with a sample of 295 students, to whom the SISCO inventory of modified academic stress was applied and a small questionnaire to collect sociodemographic data. The data was collected during the academic period between the months of March and July 2019. The results showed a statistical significance between high levels of stress and sociodemographic factors such as: female sex, the existence of family burdens, the place of Provenance, marital status (different from single), occupation (people who study and work) and the career they study. Similarly, correlation levels were found between high levels of stress and stress factors such as: time overload, academic performance, types of work, a poor understanding of the subjects of studies, second enrollment, final exams, poor grades, Limited time for homework delivery. Furthermore, the study identified a statistical correlation between high levels of stress and symptoms such as chronic fatigue, feelings of sadness, anxiety, concentration problems, and negative emotions such as irritability. Based on these results, measures were proposed that prevent the appearance of the most common symptoms.

This paper aims to replace the lead glass, used in the process of glazed tiles in the areas of San José de Balzay and Racar in Cuenca, by a glass frit that does not release lead. In these sectors it recognizes two groups, one artisan and a semi-mechanized. In this process people are in direct contact with lead oxide, which is the cause of diseases at the level of the whole organism, affecting all members of the production process, including children, adults and seniors. Use a fritted glass decreases health risks and environmental pollution. To carry out this work, it was necessary to realize a baseline survey, analysis of raw materials used, search fritted glasses in the local market, realize previous tests paste-glass coupling. To optimize dosages, we apply a Design Extreme Vertices mixtures for semi-mechanized and another for small-scale proportions for artisans. Two fritted glasses had the best results with the new dosage, although they showed crazing defect in the glaze, whereby a new optimization was performed. The results, will help to reduce the public health problem produced for the use of lead oxide and improve the technical characteristics of the product, as flexural strength and water absorption, established by the Ecuadorian INEN 990 standard.
