This paper is a summary of a thesis to get the professional title of Geographical Engineer. The burning of sugar cane is the major source of pollution in the district of Laredo and surrounding areas. This burning is done before harvest where the leaves are burned, it is done to ensure control of pests and reduce harvesting costs, while the one made after the harvest which is burned in the bag of the cane and the remaining green leaves can eliminate waste and accelerate land preparation and replanting. When cane burning is taking place, pollution occurs in form of shower of particles and fly ash together with no visible smoke and gases. Those most affected are housewives, dirty as these fly ash floors, household goods and clothes placed on clotheslines.

Ecologically-sound management plans for high-altitude grasslands of the Andes depend on an understanding the responses of plants to fire, especially the dominant tussock grasses. This study considers physiognomic responses of tussock grass in 13 sites in northern Ecuador with a known fire history, with time since fire 0.5–10 y, and a control site which had not been burned for at least 40 y. At each site, we assessed vegetation height, basal cover of the tussocks, and the ratio of dead:live leaves in tussocks. We also measured light at ground level. As recovery time increased, tussock cover and number decreased, while tussock height increased. Light levels fell sharply below the tussock canopies as recovery took place, and dead leaves accumulated quickly, reaching 60 – 70% by just two years after fire. The modification of physical tussock structure is likely to influence a much wider ...

Severe burn damage the respiratory mucosa and destroy epithelial tissue, resulting in systemic, metabolic, and sometimes fatal consequences. For decision-making, it is necessary to have easy-to-access predictors of mortality. The study's objective was to evaluate and contrast the performance of the rBaux, ABSI, and APACHE II indices as indicators of mortality in patients with significant burns. 20 papers were chosen for a bibliographic analysis, which included information on mortality, accuracy, sensitivity, and specificity of the rBaux, ABSI, and APACHE II indexes. According to AUC, the accuracy of the rBaux, ABSI, and APACHE II indices was 0.84 to 0.99, 0.85 to 0.94, and 0.64 to 0.93 correspondingly. In terms of sensitivity, APACHE II scored the highest while ABSI scored the lowest, while in terms of specificity, ABSI scored the highest while APACHE II scored the lowest. The measuremen...

Over time, the manufacturing industry has evolved enormously, requiring increasingly efficient processes, with reduced repair times and fewer defects. In this sense, in the case study a low efficiency in the production process was identified, given that the percentage in the plastics sector is 73%. Therefore, a more detailed analysis was carried out and it was found that high repair time and reprocessing due to defects are the main causes. Consequently, an improvement model based on 5S, TPM and SMED tools is proposed with the objective of reducing the costs of the described problem, which are equivalent to 7.45% of revenues. In addition, it seeks to reduce reprocesses due to defects by 43%, while repair time is reduced by 77%. Applying the presented model, it was obtained a decrease of the presented 5S deficiencies by 11.50%, increase of efficiency to 73.65%, improvement of machine avail...

The objective of this article is to offer those responsible for the Peruvian health rectorship reflections on sectoral policy derived from the study of the country’s National Health Accounts (1995-2014). While it is true that the country has increased its spending on health from 4.4 to 5.2% of GDP, 33% of its total funding comes from household «out of pocket expense», which indicates that change is necessary. Problems in the responsiveness of the health system to greater funding and public expenditure, linked to issues of rectorship and service organization, are apparent.Although there has been an increase in numbers of people with insurance, the restrictions on what is covered prevent the great majority of these people accessing health services. The most important change in the public administration of expenditure has been decentralization, while in the private administration it has...

Background: The highly stressful events we are currently experiencing require great cognitive and emotional effort and affect the mental health of the population. In this sense, coping with stress provides evidence of how people use their resources to cope with or avoid stressful events, which requires validated and reliable instruments to measure accurately. Objective: To determine the psychometric properties of reliability and validity of the BRIEF COPE 28, Spanish version. Method: The design used was instrumental; 530 people participated, 60% men and 40% women, between 18 and 60 years old, from different regions of Peru, selected by non-probability convenience sampling. Results: It is evident that the alpha coefficient of coping styles ranges from α ordinal = 0.74 to 0.82; while in strategies it was between α ordinal = 0.59 to 0.90. In terms of internal structure, the four-factor mo...

El artículo tiene como objetivo ofrecer a los responsables de la rectoría en salud las reflexiones de política sectorial que se derivan del estudio de las Cuentas Nacionales de Salud (1995-2014) del país. Si bien el país ha incrementado el gasto en salud del 4,4 al 5,2% del PIB, el «gasto de bolsillo de los hogares» constituye el 33% del total del financiamiento, lo que requiere modificar sucomposición. Se advierten problemas en la capacidad de respuesta del sistema de salud al mayor financiamiento y gasto público, que se vinculan a temas de rectoría y organización de la prestación. Si bien el aseguramiento se ha incrementado, las restricciones en la oferta impiden que las personas afiliadas a algún tipo de seguro puedan, en su gran mayoría, acceder a los servicios de salud. El cambio más importante en la gestión pública del gasto es la descentralización, mientras que e...

In Peru, the COVID-19 pandemic has had an impact on various dimensions of human and national development. While it is true that children have not been affected in terms of mortality, there is evidence of a negative impact on their development in the short and long term. In this sense, in Peru, timely and quality care through access to the integrated package of services of the Ministry of Health was severely affected, reducing its coverage and generating risk scenarios for the physical, emotional and mental development of children in the future. In this context, the State promoted temporary interventions through Emergency Decree 095-2020, includin interventions aimed at early childhood development through the National Program of Direct Support to the Poorest “JUNTOS”. This article aims to examine the implementation of these interventions by “JUNTOS”, analyze the challenges and res...

The production of organic fertilizers is crucial for the reuse of organic waste, reducing pollution and avoiding harmful emissions. The Technical University of Cotopaxi, through its Linkage Project, sought to improve waste management through the production of compost. A study was carried out in the experimental center "La Playita" in the Canton of La Maná, using 5 treatments that combined vegetable waste and bovine manure. Each treatment was replicated 4 times, using a randomized, 95% Tukey complete block design. Variables such as temperature, pH, electrical conductivity, harvest volume and mineral fertility of the fertilizer were evaluated for 15 weeks. Temperature peaked in week 3, with values between 37.45 °C and 38.95 °C in all treatments, while pH showed a tendency to decrease with increasing temperature, becoming neutralized in week 15. The final electrical conductivity was with...
