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

The Climate in Different Tourist Locations Affecting Children with Bronchial Asthma

2024 , Álvarez Sánchez, Ana , Córdova-Luspa L.E. , Pachacama-Freire M.A.

Tourist destinations are chosen by travelers according to the characteristic climate of each place. These climatic changes, allergen variations, and air pollution contribute to trigger allergens that affect bronchial asthma symptoms. In addition, the increase in temperature and carbon dioxide levels in the atmosphere could lead to a more pronounced production of pollen, which leads to the spread of allergens, increasing sensitization and aggravating allergic reactions in children, especially in those who travel to tourist places such as mountains, beaches, hills, moors, among others. Due to the increasing emission of CO2 and other greenhouse gases, both in developed and developing countries, the negative effects on respiratory health, especially asthma and allergies, are becoming increasingly important, especially in young children and the elderly. Both global climate change and air pollution have a detrimental impact on respiratory health, especially in relation to asthma and various allergic diseases. Importantly, increased emissions of CO2 and various greenhouse gases contribute to climate change, resulting in more extreme and damaging weather events, such as periods of extreme heat, prolonged droughts, severe and devastating thunderstorms, floods, and powerful tropical storms. All these extreme weather events have negative consequences for people with asthma. As a result of the research, it could be corroborated that droughts cause an increase in the concentration of various allergens in the environment, such as pollen and outdoor fungi, which can cause allergic symptoms in sensitive people. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

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.

This study examines the development and perception of sustainable tourism in Cotacachi, a region known for its rich biodiversity and indigenous culture in the province of Imbabura, Ecuador. Despite its potential for ecotourism, our survey results indicate that 66.7% of respondents are unaware of the concept of sustainable tourism and 63.3% have never participated in related activities, highlighting a notable lack of awareness and participation in sustainable practices. The research included a quantitative analysis using online surveys targeting 30 respondents, revealing that only 33.3% are familiar with sustainable tourism. Furthermore, although 50% of participants recognize the importance of these practices, there is a significant discrepancy in the perception of their relevance, suggesting a divide in the understanding and appreciation of sustainable tourism. The results highlight the need for intensive educational programs that not only promote awareness of sustainability but also integrate the community into the planning and benefits of tourism. The sustainable tourism plan proposed in this study seeks to improve the visibility and accessibility of Cotacachi’s natural landscapes, promote the inclusion of indigenous communities in tourism, and strengthen environmental conservation efforts. It is suggested that these efforts could enrich the tourism experience while stimulating local economic development, supporting biodiversity conservation, and reinforcing the region’s cultural identity. Through a holistic approach, the study proposes to transform Cotacachi into a model of sustainable tourism, ensuring long-term benefits for both the community and the environment. The study further revealed that 60% of respondents are aware of Cotacachi’s food fair that connects farmers with merchants, representing a sustainable practice. However, further dissemination and participation in these events is still lacking. For future research, it is recommended to continuously monitor perception and participation in sustainable tourism, in addition to assessing the economic, social, and environmental impact of the proposed interventions. With these measures, Cotacachi can move toward truly sustainable tourism that equitably benefits all stakeholders.

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.
