Sustainable Ergonomic Assessment in the Poultry Industry with Prevention of Musculoskeletal Injuries through Efficient Methods

2025 , Álvarez Sánchez, Ana , Suárez del Villar, Alexis

The research analyzed ergonomic issues and musculoskeletal risks related to manual load handling in an Ecuadorian poultry microenterprise, aiming to develop preventive measures. By examining the unloading processes, the study identified high-risk postures and movements using the Ovako Working Posture Analysis System (OWAS) and Snook and Ciriello methods, assessing both posture and load dynamics. Results pinpointed critical ergonomic risks requiring urgent intervention, particularly in positions involving heavy lifting, like feed sack transportation (Alvarez Sanchez A. Human interaction and emerging technologies (IHIET 2022), 2022). Data were gathered through direct observation and photography, analyzed with ERGOsoft PRO software to quantify the ergonomic risks effectively. High-risk postures (positions 9, 10, and 11) were identified, falling into risk category 4, necessitating immediate corrective actions. The analysis also highlighted secondary risks related to task frequency, duration, and inadequate breaks, emphasizing the negative impact of poor lifting techniques. The recommendations from this study stress restructuring tasks to minimize harmful postures, enhancing training on proper load handling, and integrating mechanical aids to alleviate physical strain. Additionally, it advocates for biannual health screenings and continuous ergonomic reassessment to maintain worker health and enhance productivity. The implications of this research underscore the necessity of proactive ergonomic risk management within the poultry industry. By implementing these targeted interventions, the microenterprise can significantly reduce the incidence of musculoskeletal disorders, promoting a healthier work environment and improving overall operational efficiency.

Strategies to Produce Environmentally Friendly Cleaning Supplies for Tourism in the Galapagos Archipelago

2024 , Álvarez Sánchez, Ana , Suárez del Villar, Alexis

The implementation of disinfectants in the Galapagos Islands requires a meticulous and thoughtful approach, given the ecological sensitivity of this protected area. Disinfectants must be biodegradable and non-toxic to preserve the unique terrestrial and marine biodiversity of the islands. Their effectiveness against a variety of pathogens is critical to protect public health, but this must not compromise the integrity of aquatic and terrestrial ecosystems. Adherence to strict environmental regulations and the provision of clear information on their use are imperative to ensure that their application is both safe and responsible. Maintaining this delicate balance between the protection of human health and the conservation of the unique ecosystem of the Galapagos Islands is crucial, and the disinfectants used play a key role in this effort. The microenterprise under study is dedicated to the manufacture of cleaning products such as disinfectants, liquid soap, and fabric softener for the hotel sector on Santa Cruz Island, Galapagos Archipelago; 8 years ago, due to external factors on the island, the company presented an increase in sales, resulting in inefficiency in the manufacturing process due to lack of capacity, the physical space where it processes was not designed for this business as it is located within the property of the owner of the company, for this reason the 30 m2 that are currently used do not have inventory areas of raw materials, material in process and finished products, which can meet the current demand for production. By using manual processes for the manufacture of the products, the transformation time varies between 1 and 2 days for each reference, which delays delivery times, creating failures that contribute to the non-fulfillment of orders. By diagnosing the mixing and packaging operations that directly influence the failure to deliver products to the final customer, an improvement proposal is made to take advantage of the capacity of the areas [1], reduce waste and minimize the ergonomic risks of the current production line to increase its productivity and satisfy the demand of its customers

2024 , Suárez del Villar, Alexis , Álvarez Sánchez, Ana

The implementation of an optimization strategy in a company dedicated to the sale of laboratory equipment and reagents is detailed. Initially, two routes were established with the objective of significantly reducing delivery times and related costs. These routes were designed using linear programming methods, considering elements such as vehicle carrying capacity, time constraints and customer requirements. After defining the routes, they were incorporated into the company’s operations, adjusting the delivery schedule, and allocating the appropriate resources for the execution of the new logistics plan. In addition, a system was implemented to regularly monitor and control the results, allowing necessary adjustments to be made. The implementation of these measures proved successful, reducing delivery time by 321 min, equivalent to 5.35 h, and saving USD 51.54 per kilometer. This led to a substantial improvement in the company’s logistical efficiency and customer satisfaction. It is recommended to maintain weekly monitoring and control of the implementation, evaluating the results periodically. It is also advisable to regularly check the vehicles used in transportation to ensure their optimal condition and guarantee efficiency and safety in deliveries. The possibility of applying this optimization proposal in other companies in the same sector is raised, given that the positive results obtained could be replicable in similar organizations. In conclusion, the application of this optimization proposal in the laboratory material and reagents company has proven to be extremely effective, reducing delivery times and associated costs, while improving operational efficiency and increasing customer satisfaction.

Ancestral Gastronomic Knowledge: A Key to Boost Tourism in Ecuador

2025 , Álvarez Sánchez, Ana , Alisson Doménica Espinosa-Rueda , Suárez del Villar, Alexis

Globalization has had a significant impact on local cultures around the world, especially evident in Ecuador, where the rich tapestry of traditional gastronomy plays a crucial role in defining the nation’s identity; as the world becomes more interconnected, Ecuador’s younger generation, like their counterparts in many developing countries, is increasingly leaning toward foreign cuisines, often perceived as more modern or trendy. This shift not only neglects the diverse culinary heritage specific to various Ecuadorian regions, but also undermines the potential of traditional foods to attract tourists seeking authentic experiences. Ecuadorian gastronomy, with its unique flavors and textures, offers a window into the country’s cultural practices and history, making it an integral part of the tourism industry, but the gradual loss of this culinary heritage as local preferences evolve poses a threat not only to cultural identity, but also to the economic benefits derived from gastronomic tourism. Using the literature review method, this study collected and analyzed data from various documents highlighting the importance of local cuisine to the tourism sector. The results underline the need to strategically focus on revitalizing and promoting traditional Ecuadorian dishes to counter the influence of global food trends; also, the research delved into the reasons for young people’s inclination toward foreign cultures, suggesting a disconnection with their own cultural roots. It critically examined how this distancing could be reversed by fostering a deeper appreciation and understanding of local traditions. By promoting a reconnection with their gastronomic past, Ecuadorians can leverage their rich culinary heritage as a key asset to boost tourism. This not only enhances the authenticity and attractiveness of the tourism experience, but also supports local economies. Ultimately, the study confirms that preserving and celebrating ancestral gastronomy can play a critical role in sustaining tourism and maintaining cultural identity in the face of globalization.

Software and Methods Applied in the Standardization of the Grinding Process for Automobile Engines as a Business Solution

2024 , Álvarez Sánchez, Ana , Suárez del Villar, Alexis

When the research addresses the problem of empirical engine rectification based exclusively on the experience of the workers, which results in nonconformities on the part of the customers due to delays in delivery times. To solve this, it was proposed to standardize the operation cycles using the Stop and Observe Method. Through techniques such as direct observation, time studies and process diagrams, the grinding process was analyzed in detail. The data collected were compared with the Crystal Ball program, demonstrating consistency with 95% confidence. It was determined that the time required to rectify an engine was 27.23 days, with supplements affecting 4.8 h of an 8-h workday. The investigation proposed improvements, including the implementation of a hydraulic scissor table to reduce the physical strain on the operators and the introduction of hearing protection. This resulted in a noise reduction from 30 dB to 15 dB, exceeding the regulations of Executive Decree 2393. With these measures, the total grinding time was reduced to 26 days, representing an efficiency gain of 639.15 min or 10.65 h. This standardization not only improves the efficiency of the process, but also allows for more accurate communication with the customer on delivery times, increasing customer satisfaction.

Exploring Challenges and Strategies for Measuring the Social Impact of Entrepreneurship in Ecuador

2025 , Álvarez Sánchez, Ana , Suárez del Villar, Alexis

Research conducted in Ecuador reveals that while 27% of entrepreneurs surveyed identified lack of liquidity as their main challenge, another 23% highlighted low sales as a significant obstacle, and 19% pointed to insecurity. These challenges vary markedly between regions such as Pichincha, Guayas, Manabí and Azuay, which complicates the standardization of methods for measuring the social impact of ventures. Through qualitative interviews and quantitative analysis of INEC data, it was observed that less than 40% of entrepreneurs in Pichincha are trained in impact assessment techniques, which contrasts with the need for training and tools adapted to local contexts. This lack of preparation underlines the urgency of developing customized methodologies that allow entrepreneurs and policy makers to better understand and support the sustainable growth of entrepreneurship in each province. The need for adaptation and customization of measurement tools is evident, particularly in provinces where economic and cultural characteristics vary significantly, e.g. in Azuay, where the artisanal sector is preponderant, it would be beneficial to implement measurement systems that consider cultural and community impacts in addition to economic ones, and collaboration between academia, government and non-governmental organizations can provide vital support in the creation of these methodologies, ensuring that they are robust and relevant. By fostering a stronger environment for social impact measurement, supportive policies could be improved, thus contributing to more equitable economic and social development in Ecuador. This study suggests a clear path towards creating a more effective framework for assessing and maximizing the social impact of ventures, opening up opportunities for future research that delves deeper into the interaction between public policies and entrepreneurial practices in different regional settings.

Navigating the Health Care Transition for Migrant Women in the Andean Diaspora with Challenges and Solutions

2025 , Álvarez Sánchez, Ana , Suárez del Villar, Alexis

The study focuses on the integration of migrant women in Andean public health systems, highlighting the persistent challenges despite recent legislative and programmatic advances; through a qualitative approach, using semi-structured interviews, content analysis and case studies, it addresses the cultural, linguistic and structural barriers that still limit the effective access of these women to essential health services. Communication and cultural barriers were identified as the main obstacles faced by these women, significantly affecting the quality of medical care received. The analysis reveals that approximately 85% of migrant women report difficulties in communicating with health personnel, which highlights the need to implement translation services and cultural competency training programs. In addition, it is noted that interventions that integrate cultural and linguistic considerations show a 40% improvement in the effectiveness of medical care. Seventy percent of health professionals recognize resource shortages as a critical constraint to effective service delivery, indicating a significant gap in the health infrastructure that needs to be addressed to improve accessibility and quality of health care. The researchers propose a more holistic and culturally adaptive approach to policy formulation could significantly improve the accessibility and quality of healthcare offered to migrant women. This would include improving coordination between mental and physical health services and implementing more inclusive policies that consider the specific needs of migrant women. The research emphasizes the importance of incorporating multidisciplinary perspectives that address both mental and physical health, as these aspects are deeply interconnected and significantly affect women’s ability to integrate into new social and economic environments. It is stressed that, to improve the health situation of migrant women, it is crucial that future public health programs and policies incorporate a targeted and specialized approach that is sensitive to the cultural and linguistic differences that characterize this population. This will not only facilitate better integration of migrants into health systems but will also contribute to their well-being and overall public health

AN ASSESSMENT OF CUBAN FOOD SECURITY BASED ON THE AGRICULTURAL AREA UNDER CULTIVATION AND AGRICULTURAL YIELDS

2022 , Cosío, E.C. , Suárez del Villar, Alexis , Álvarez Sánchez, Ana , Cruz, I.A.

The research was carried out with official data published in the country, collected from official information sources from 2007 to 2019. In the variables analyzed, the following were considered as having high explanatory power: land distribution, total area, agricultural area, cultivated area, yields of selected crops. For the calculation of the nutritional needs of the population, the nutritional recommendations for the Cuban population were taken into account and the productions were grouped ac-cording to the classification established for the food groups in Cuba. The country’s agricultural area is 6400.18 Mha in 2019, which its use decreases for all the items studied, except for banana, bell pepper, bean, lemon, guava and pump fruit. In addition, yields of the main crops are low, as is the productivity of the livestock sector analyzed. To contribute to the achieve-ment of food security for the Cuban population in correspondence with the standards of the National Institute of Nutrition, an area with technological package (irrigation and optimal yields) of 3942577.82 ha is needed, existing agricultural area in the country; and without technological package (without irrigation), an area of 6424285.82 ha, which are insufficient in 23485 ha. © 2022, University of Cienfuegos, Carlos Rafael Rodriguez.
