Background: the respiratory system assessment has evolved substantially since the advent of X-rays. Tomography has been one of the primary tools for the diagnosis of atypical pneumonia, since it helps to better visualize the thoracic anatomy by providing excellent sharpness, resolution space, it is also an essential resource for delimiting the lung involvement caused by SARS-CoV-2. Objective: to determine the prevalence of radiological findings in atypical pneumonia caused by SARS-CoV-2, diagnosed by simple chest computed tomography in patients attended at the imaging center of the “Hospital Monte Sinaí” in May- November 2020. Methodology: a retrospective cross-sectional descriptive study was carried out. The universe was the radiological reports and patient record card of simple chest tomography studies performed in the imaging center of the “Hospital Monte Sinaí” in May- November 2020 period. Results: according to the data analysis, 413 patients (33.74%) presented SARS-CoV 2. The prevalent sex is male (55%), and the age group with the highest prevalence is in the age of 50-59 years range (25%), the prevailing radiological finding was ground glass (51.88%) and the zonal distribution of the lung parenchyma with the highest prevalence was mixed (55.69%). Conclusion: The percentages obtained from the study are very similar to others in terms of age prevalence, sex, and radiological SARS-Cov-2 findings.

(Universidad de Cuenca, 7-07-06) Cornejo Chacha, Edgar Dario; Billazhiñay Zhapán, Juan Andrés; Varela Solano, Ramiro Xavier
Physical activity is a fundamental axis for the welfare of people, accompanied by proper nutrition, favor the prevention of high-risk diseases, including the psychological aspect as it improves the self-concept of themselves, all this demonstrated by various studies, which show us countless benefits for all, and due to the situation through which the world went through because of the pandemic by COVID-19, we must emphasize the importance of physical activity and maintaining good eating habits in favor of our health, that is why this study aims to identify the effects generated by the confinement and social isolation due to the pandemic COVID-19, on the level of physical activity and eating habits in young school children between 14 and 17 years, through the application of questionnaires such as: Eating Behavior and the International Questionnaire of Physical Activity, questionnaires that consist of sections of a before and during the confinement because of Covid-19, the application of these questionnaires will be to students of the Unified General High School of the Alicia Loza Meneses Fiscomisional Educational Unit in the school year 2020 - 2021. Finally, it was found that there are not so significant statistical changes in the level of low physical activity (31.5%- 33.1%), moderate physical activity (24.6%-25.4%) and high physical activity (43.8%-41.3%), where it is evident that most students are physically active. With regard to eating habits, it was determined that both the consumption and preparation of food improved significantly during the Covid-19 pandemic.

Relación entre los niveles de la hormona Anti-mülleriana y la respuesta ovárica a los tratamientos superovulatorios en vacas mestizas Holstein
(Universidad Zulia, 0022-01-04) Dután Sanango, Jorge Bolívar; Hernández Fonseca, Hugo; Ayala Guanga, Luis Eduardo
This research was conducted in the south-central region of Ecuador. Anti- Müllerian hormone (AMH) concentration was determined and a reference value was established to predict the ability of donor cows (Holstein crossbreds) to produce follicles in response to superovulation protocols that provide numerous oocytes and embryos in vivo. In the first experiment 140 cows received a synchronization protocol to reinitiate the follicular wave. On day 11 of the protocol, AMH concentration was measured and antral follicle counts (AFC) ≤ 4mm were performed. It was observed that AMH concentrations correlated positively with AFC (r=0.783). The second experiment related AFC, AMH levels and response of 36 in vivo embryo donors to a superovulation protocol. The number of follicles observed on day 9 in the high AMH group (23.1 ± 1.28 follicles) was greater than cows in the low AMH group (13.1 ± 0.76 follicles). The ovulation percentage was greater in the high AMH concentration group (26.3%) versus the low concentration group (13.3 ± 0.97 vs. 9.8 ± 0.57 CL). In addition, more embryos were recovered in the high (8.2 ± 0.77) vs. low AMH group (3.2 ± 0.50). Finally, the third experiment related AMH concentration to the number and quality of cumulus-oocyte complexes (COC’s) recovered from heifers by ultrasound-guided aspiration (OPU). Sixty-one crossbred Holstein heifers with high, medium and low AMH concentration were evaluated. It was determined that plasma AMH levels were positively and significantly related to the total number of antral follicles <4mm at the time of restarting the follicular wave (r=0.93). In addition, animals with high AMH concentration presented twice the number of follicles on the day of OPU compared to animals with low AMH concentration (24,8 ± 0,52) versus (11,6 ± 0,36) respectively. Likewise, although a similar recovery percentage (57%) was obtained in both groups, the greater number of follicles in the high AMH group allowed obtaining twice the number of suitable COC's for in vitro embryo production.
El Clóset
(Universidad de Cuenca, 22-11-11) Castillo Flores, Hugo Patricio; Falconí Abad, María Monserrath
The closet, in its most basic meaning, is defined as a piece of furniture where we place everything we decide to keep or hide, but what happens when people use it to mask their sexual identity? In this case, "the closet" becomes a space that can be explained from heteronormativity and is used as a mechanism of biopolitical control through which families and society exercise power over the body and sexuality of its members, of those who subvert the norm in sexual matters. This research seeks to analyze the social factors that drive a person to assume or not, in the public eye, his or her homosexual identity within what is commonly referred as "coming out of the closet", as well as to expose the effects of the process of such coming out in the lives of the investigated subjects and their closest relationships. To achieve these objectives, the research work is expressed through the production of an ethnographic documentary video made with five homosexuals from the city of Cuenca-Ecuador, who, through an ethnographic method and a qualitative approach, expose their life experiences in relation to the so-called "closet". The study showed that "the closet" is a very complex symbolic space, both imaginary and real, that simultaneously represents subordination to the hetero-patriarchal system and submission to the norm in order to live and belong in our modern societies. Therefore, the "closet" is a space from which one never fully emerges; it is a threshold that is permanently crossed.

Sistema constructivo de viviendas con paneles BTC y Bambú
(Universidad de Cuenca, 31-03-03) Farfán Fajardo, Carlos Eduardo; López López, Carlos Andrés; Cárdenas Haro, Xavier Ricardo
In this degree work, a proposal for a scalar house with a bamboo construction system and prefabricated BTC panels was proposed, in order to develop a house with low-cost prefabricated materials, with a low environmental impact and easy construction, which allows the user to make the necessary extensions based on their needs. We started from the analysis of the main materials used, bamboo and earth, which are abundant in the environment and their cost is low compared to others, knowing their behavior, advantages and disadvantages, we developed an architectural proposal of modular and scalar housing, with bamboo structure and prefabricated BTC panels, this design should meet the needs of an average family, so we start from the modular and functional analysis of the kitchen, which is proposed as the most important area of the house and around which the whole house is developed, With the architectural proposal proposed, the construction system was developed, following the same principles of low cost, easy construction and scalability, which is why it is proposed bolted joints which allow changes and extensions in the structure, as final points, but equally important, through the use of digital tools the seismic behavior of the house is simulated and necessary reinforcements were proposed, the process culminated with the development of a budget in which it is analyzed whether the proposal is viable or not, economically.

Diseño de un plan de vigilancia de la salud para los trabajadores de la Función Judicial del cantón Cuenca
(Universidad de Cuenca, 200-10-15) Tuba Criollo, Ana Cecilia; Nivelo, Marco Antonio
Occupational health and safety as a fundamental part of industrial safety and hygiene, imposes a regulatory, moral and economic obligation on organizations, contributing to the well-being of employees and job performance. Therefore, aspects of safety are increasingly incorporated in institutions, as a fundamental element for the development of activities, from where all the different organizational levels play an important role in improving industrial safety and hygiene. The objective of this work was to design an occupational health surveillance program for workers in the Judicial Branch of the Cuenca canton, which is guaranteed by the Constitution of the Republic and national legislation. The study methodology is qualitative, since the information was qualified through the collection of data and information directly. It was concluded that, since there was no tool to help organize occupational health surveillance in the institution, the implementation of an operational guide for different jobs was proposed in order to carry out initial, periodic medical care, change of post, reinstatement and departure of the worker, as well as the development of healthy activities for workers that guarantee their physical, mental and social health in the workplace from a preventive medical approach, motivating the implementation of the surveillance program, its compliance and continuous improvement
