2024-04-10T21:00:52+00:00

The present study was born from the "Bridges" chair, which, by taking advantage of the different typologies presented by these structures located on the Burgay river in the city of Azogues, was intended to study their geometry, typology and material, with field trips. But during the inspections carried out, several problems were identified, which led to the generation of a specific study of the pathologies of the bridges located in the urban area of the city. The absence of preventive maintenance of the same was evidenced. It is mainly observed humidity, vegetation, corrosion, carbonation, permanent deflection and lack of elements such as expansion joints and neoprenes. Seven bridges were evaluated, the first being the García Moreno bridge, located in front of the Homero Castanier Crespo Hospital, and the study was completed on the bridges built on Av. 16 de Abril. This analysis contemplates structures with materials such as reinforced concrete, steel, masonry. As typologies, there are various forms, bridges on beams, both in reinforced concrete, and mixed (steel - concrete), bridges in face and post-tensioned. It is concluded that corrective maintenance is necessary as soon as possible and later have a preventive maintenance plan, which guarantees the useful life and adequate structural behavior of these important structures.

La evaluación del comportamiento de la vía Panamericana Norte en Azogues, Ecuador, mediante el método PCI (Índice de Condición del Pavimento). Se examinan investigaciones anteriores que utilizaron este método para evaluar carreteras en distintas zonas de Ecuador, resaltando las variaciones en el estado de las vías debido al tráfico pesado y al transporte público. El propósito principal es analizar de manera precisa la condición del pavimento en la vía Panamericana Norte en Azogues a través del método PCI como herramienta de evaluación.

El PCI se destaca por su importancia al detectar áreas críticas de deterioro en pavimentos flexibles, como grietas, hundimientos y parches. Su estrecha correlación con la seguridad vial resalta la urgencia de adoptar medidas correctivas y realizar un mantenimiento adecuado.

El estudio presenta las fases esenciales del PCI, desde la revisión visual hasta el cálculo del índice de condición, subrayando su relevancia en la determinación de estrategias de mantenimiento, la óptima asignación de recursos y la planificación de futuras intervenciones.

Impact of the use of web applications on the MiPymes of the city of Azogues

2024-07-02T19:00:16+00:00

This research project aims to analyze the potential impact of web applications on Micro, Small, and Medium Enterprises (MSMEs) in the city of Azogues. The goal is to determine if the adoption of web-based technological tools can enhance the efficiency and productivity of these businesses, as well as their ability to compete in the local market. Through an experimental research approach with a quantitative focus and the application of surveys to MSMEs and their customers, the benefits and challenges associated with the implementation of web applications for business activities automation will be explored. This will determine if the adoption of web-based technological tools can improve the efficiency, productivity, and competitiveness of the studied businesses in the local market, through experimental research with a quantitative focus and the application of surveys to MSMEs and their customers. After conducting quota sampling of nearly 2,000 companies filtered from the SRI Catastros list of the Cañar province, a comprehensive survey was conducted covering 164 participants considering the urban area of Azogues, representative of an estimated population of 1,016 active SMEs. It is evident that 59.4% of them are traditional businesses, and there is a significant lack of knowledge and access to technological tools, highlighting the urgency of implementing solutions to enhance their development and competitiveness in the market as none currently use business management systems, preferring traditional methods. Additionally, 70% of respondents have access to mobile devices and the internet, suggesting the viability of implementing a system that improves SME management and contributes to economic growth.

USE OF CHEMICAL FERTILIZERS IN THE PROMOTION OF AGRICULTURAL PRODUCTION IN ECUADOR

2024-07-03T19:59:36+00:00

The present study evaluates the impact of the use of chemical fertilizers on agricultural development in Ecuador, a country where agriculture plays a crucial role in both economic development and food security. Through a statistical analysis of data from the 23 Ecuadorian provinces, it explores how the intensive use of fertilizers affects agricultural productivity and the environment. The research reveals that, although chemical fertilizers increase the productivity of key crops such as potatoes and naranjilla, their excessive use causes serious soil and water pollution problems, negatively affecting biodiversity and human health. The theoretical framework reviews previous studies that highlight both the benefits and limitations of using chemical fertilizers. The methodology used includes a linear regression to examine the relationship between the use of fertilizers and agricultural development, controlling variables such as agricultural development, associativity and rurality. The results show a significant negative effect of fertilizer use on agricultural development, suggesting that dependence on these inputs can lead to a "fertilizer trap", where farmers must continue investing in fertilizers to maintain productivity, resulting in a spiral. of debt and poverty. The study concludes that, to ensure long-term agricultural development, it is crucial to adopt more sustainable practices, such as the integration of organic and chemical fertilizers, and improve the training of farmers in the proper management of these inputs. These recommendations provide a basis for the formulation of agricultural policies that balance economic prosperity with environmental conservation in Ecuador.

Public intervention in the provision of drinking water services in the communities of the rural Nankais parish, Nangaritza canton, province of Zamora Chinchipe

2024-07-04T14:42:44+00:00

This research arises in response to the problem of access and quality of drinking water in specific rural communities such as Pachkius, Wankius, Los Diamantes, Los Hachos, San Manuel, San Andrés and Naichap. To this end, public intervention strategies were analyzed in the provision of drinking water services in the communities of the rural Nankias parish, Nangaritza canton, province of Zamora Chinchipe. Through surveys and focus groups, it was found that only 13% of respondents have direct access to a public drinking water distribution network, while 75% of the population receives raw, untreated water. Only 25% have water supply 24 hours a day. These conditions have generated widespread dissatisfaction with the quality of the water provided. In this context, building a drinking water treatment plant emerges as an essential and priority measure to address the crisis.

Effective management of academic networks in research

2024-07-04T15:02:13+00:00

The theme of this editorial is oriented towards an analysis of an activity that, as researchers, we must pray for every day, or at least once a week. That is, the management of the academic and scientific networks to which we are indebted. And the question will arise: why? Because it is essential to make our profile as active researchers visible in order to make visible and project the impact of the work we do.
