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.

Design of a Semi-automatic Dough Mixer for the Prevention of Occupational Diseases in Marzipan Artisans

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

Older people, due to the natural aging process, are particularly vulnerable to occupational tasks, as they experience a gradual loss of physical capacities, which increases the incidence of occupational diseases in this population. Despite these challenges, their experience and skills acquired over the years make them a valuable resource for society. This study focuses on designing a semi-automatic dough sheeter for the dough making process used by the artisans of Calderón in Ecuador, who currently carry out this work manually, this practice being an integral part of the local culture. The research began with a detailed analysis of modern manual molders, collecting data on shear force, bending moment, and tensile stress, which are fundamental to the design. Subsequently, a simulation of the design was carried out using SolidWorks software. The result was the creation of a prototype kneading machine equipped with AISI 1050 steel rollers, processed by HR. This device was able to significantly reduce repetitive hand movements, reducing the effort during the kneading process by 25,000 TMU, which translates into improved health and work performance for the artisans. The implementation of this technology reduced the risk of occupational diseases such as bursitis, which is caused by inflammation of the bursae in the joints, and carpal tunnel syndrome, which affects the functionality of the hands. In addition to the physical benefits, this project also addresses the psychological aspect, as many older craftsmen and women feel demotivated due to their diminished ability to perform tasks they used to do in their youth. The research aims to provide a better quality of life for these workers, protecting both their physical health and emotional well-being. In short, the semi-automatic laminator not only improves the working conditions of the Calderon artisans but also preserves and promotes an important cultural tradition, ensuring that these valuable knowledge and skills can continue to be practiced in a safe and sustainable manner.

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

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.

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.
