2023 , Bustán-Gaona D. , Ayala-Chauvin M. , Buele, Jorge , Jara-Garzón P. , Riba-Sanmartí G.

Vernacular architecture is an architectural style that reflects the traditions and cultural aspects of a particular region or community. It is characterized by the use of local materials and traditional construction techniques, adapting to the climatic, geographical, and cultural conditions of the place. Despite extensive research on the benefits of natural lighting in modern architecture, there is limited understanding of how vernacular architecture integrates natural lighting principles in various climatic conditions, mainly due to restrictions in intervention and concerns about structural integrity. In today's world, energy efficiency and conservation are crucial aspects of building design. Therefore, this study aims to analyze the effectiveness of natural lighting in the indoor spaces of vernacular architecture. The research includes measurements taken in traditional buildings in the parish of Pasa, Ambato, Ecuador, as well as simulations to evaluate the behavior of sunlight. The findings reveal that, with new construction technologies, lighting levels in the interior spaces of these buildings can be improved. To address this issue, a proposed solution is presented to optimize the use of natural light, resulting in an increase from 30 to 100 lx. This improvement could pave the way for the implementation of policies that enhance the quality of life for users. © 2023

The Robot Operating System (ROS) is a middleware that standardizes robot programming, both in simulation and with real equipment. Despite this open-source tool being available for several years, there's still a need to enhance its utilization in robotics education across all educational levels. In this study, a ROS class is assessed among university students using a commercial educational robot. The primary objective is to measure academic emotions in learning and student performance to determine the impact of the class using the open-access tool from a GitHub repository (https://github.com/joseVarelaAldas/ROS-Crowbot). This tool is based on the rosserial package, compatible with the ESP32 board. For class, CrowBot robots connected to the local wireless network via WiFi are used. TThe participants in this study were eight students from an electronics degree program at a higher education institution, who had no prior experience with ROS and received practical training using the educational mobile robot. For data collection on class performance, three parameters are assessed: execution time, functionality, and motivation, and to measure academic emotions, a validated self-report instrument is used. The results show an overall performance of 82.1%, and in the self-report on academic emotions, a high score in enjoyment (95%) and the lowest score in boredom (24.1 %) were obtained. In conclusion, the repository provides an interesting, practical, and accessible tool for an introduction into the world of robotics using ROS.

Analysis of Musculoskeletal Disorders in University Administrative Staff: A Necessary Ergonomic Assessment

2024 , Cruz-Salazar R. , Buele, Jorge

Musculoskeletal disorders in work environments with repetitive tasks and long-period forced postures are common. A university’s administrative staff presented a high incidence of musculoskeletal disorders in the neck, lower back, shoulder, and wrist. Preventive measures should be taken to improve ergonomic conditions and minimize the risk of chronic injuries. The evaluation using the RULA method, and the Nordic Questionnaire revealed a medium to a high incidence of musculoskeletal discomfort in administrative staff. The position adopted by users strongly influences this situation, and it is recommended to follow ergonomic recommendations to minimize ergonomic risks. Forced postures in specific body areas, such as the neck, shoulder, and wrist, should be corrected with changes in the task and study, even redesigning them. The Nordic Questionnaire found that 100% of the participants feel neck, lower back, and elbow discomfort and 87.5% in the shoulder and hand/wrist. The discomfort lasts over three months, forcing 87.5% of people to change jobs. The intensity of the discomfort is moderate, and its origin has been mainly forced postures in the neck and lower back and repetitive movements in the hand/wrist. This shows the need to take preventive measures to improve ergonomic conditions and reduce the risk of injuries and chronic discomfort in employees. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Psychological and sociodemographic factors associated with hypoactive sexual desire in Ecuadorian women

2024 , Pérez Vega, Doris , Subia Arellano, Andrés , Buele, Jorge

Introduction: Human sexuality is a multifaceted process, and sexual desire plays a central role in the triphasic model of the sexual response cycle, as proposed by Helen Singer Kaplan. Methods: In this cross-sectional correlational study, we examined the relationship between various sociodemographic factors, such as age and motherhood, and sexual variables, including erotophobia, erotophilia, homophobia, and unconventional sex, with hypoactive sexual desire in women from Quito, Ecuador. The study sample comprised 421 women between the ages of 18 and 50, who were administered the Revised Sexual Opinion Survey and the Inhibited Sexual Desire Scale to assess their sexual attitudes and levels of desire. Results: The findings revealed that age (F = 7.13, p < 0.001) and motherhood (F = 13.72, p < 0.001) had a significant impact on inhibited sexual desire. Furthermore, significant correlations were observed between inhibited sexual desire and age (r = 0.16, p < 0.001), motherhood (r = 0.18, p < 0.001), erotophobia (r = 0.19, p < 0.001), erotophilia (r = −0.21, p < 0.001), and homophobia (r = −0.18, p < 0.001). Discussion: These results suggest that women who are older, mothers, or have higher levels of erotophobia are more likely to experience hypoactive sexual desire. In contrast, higher levels of erotophilia and homophobia were inversely related to hypoactive sexual desire. This contributes to a deeper understanding of how different personal and sexual attitudes influence sexual desire in Ecuadorian women.

Mobile Manipulator for Hospital Care Using Firebase

2022 , Varela Aldas, José , Buele, Jorge , Guerrero-Núñez S , Andaluz V.H.

The COVID-19 pandemic has shown that the use of the technology in medicine is no longer a luxury, but a necessity. The use of the robotics in the treatment of diseases and physical therapies is limited in Latin America due to the high acquisition and maintenance costs. This document proposes the design, development, and evaluation of a robotic system for the guided monitoring of patients, through remote control using a mobile application. Within the methodology, four phases were proposed: planning, design, development, and evaluation. The 3D design is done using the Tinkercad software, which facilitates the construction of the pieces using 3D printing technology. The ESP32 board is the main element that receives the signals from the sensors and controls the actions of the actuators through the orders received from Firebase. For the development of the application, App inventor is used, building a friendly and easy-to-use interface. To validate this proposal, experimental tests were carried out with two patients in a medical center. In addition, a parameter compliance questionnaire was applied to the robot, obtaining a score of 92.6%, and the mobile application obtained 72.5% in the usability test. All this confirms an efficient care proposal, with a reduced investment. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Impact of different types of rennet on sustainability and safety in cheese production

2024 , Buele, Jorge , Michael Villafuerte , Steven Paucar , Lara Calle, Andrés

Cheese production, an ancient technique that has endured through the centuries, has evolved to incorporate a variety of coagulants, each with specific characteristics and applications. However, the industry now faces a sustainabilityrelated challenge: the need to find ethical and efficient alternatives to calf rennet, as its use raises significant environmental concerns, as well as ethical and occupational health issues due to exposure to contaminants in the production environment. This study explores how different types of rennets (animal, vegetable, microbial, and recombinant) can contribute to a more sustainable, productive, and safer cheese production, adapting to the growing market demands for environmentally respectful practices. Through a methodology that included a literature review, the characteristics of these rennets and their effect on the organoleptic, microbiological, and productivity aspects of cheese production were identified and compared. The results indicated that, although calf rennet remains preferred for its coagulating properties, vegetable and microbial alternatives are gaining ground due to their adaptability, efficiency, and lower environmental impact. This diversification of rennet sources not only meets ethical, commercial, and food security demands but also affects the income of small producers by enabling more sustainable practices. However, more empirical research is needed to optimize these processes across different production contexts and enhance both productivity and sustainability.
