The research is framed in the design of didactic material, under the perspective of product design. As a discipline of study, it focuses on the needs and<br>particularities of the rural educational environment and attempts to support the integral development that Ecuadorian education has been pursued. In this context, with a qualitative approach, the characteristics of the environment are collected, as well as the perspectives of basic general education teachers, in<br>relation to the integral education and the existing materials in formal education. In a comparative analysis, we analyzed data obtained with similar training projects, which show the importance of working on social skills in children. The results determine parameters and requirements to develop didactic products that complement education, based on concepts of design, pedagogy, and didactics as knowledge-building tools.</p> <p><strong>Keywords:</strong> Product Design, Teaching Material, Comprehensive Training, Social Skills.</p> 2022-03-31T09:13:22+00:00 Copyright (c) 2022 Daniel Davila Leon, Karen Aigaje, Mario Caiza, Michelle Flores, Jhoel Vazquez Emotional dependence in university students in a period of confinement due to covid-19 2022-04-28T11:47:56+00:00 Maryori Peredo Nathaly Mamani Carmen Lazo Sheril Condori <p>An analysis of the level of emotional and dependency according to sociodemographic characteristic factors in university students in a period of confinement due to COVID-19. 689 female students of the city of Arequipa were included; we used a measurement instrument with 23 items that allowed us to understand the influence of the current situation on the psychological state of the university. The results indicate that there is a low level of emotional dependence, in relation to the variable of the emotional situation being one of the main reasons why single students are less likely to have this dependence as they do not have any type of romantic relationship, since they focus more on their personal goals through their university studies, which shows that they are more independent when taking on challenges and objectives consistent with their academic training, compared to those who maintain a relationship.</p> 2022-03-31T10:27:09+00:00 Copyright (c) 2022 Maryori Peredo, Nathaly Mamani, Carmen Lazo, Sheril Condori Pandemic Triage Criteria by COVID-19: Multiple approaches 2022-04-28T11:47:41+00:00 Veronica Luzuriaga Gabriela Rueda Josue Quiroga Gitti Montesdeoca Jose Calahorrano <p>This paper presents the most relevant criteria considered in the face of a lack of resources and medical infrastructure to prioritize the treatment of patients affected by the COVID-19 pandemic.

The data analyzed were obtained from surveys of 75 students of various educational levels in aspects such as quality in teaching, accessibility to virtual resources, teacher training, continuity of the curriculum, equal conditions, and the influence of policy on the quality of education in general. It was concluded that the educational process in its virtual modality is acceptable from the point of view of intrinsic advantages such as flexibility and yet there is also a change of focus in the educational institution that pays attention to providing a better virtual educational process diverting attention from equally important processes such as the communication of internal and external actions to the institution.</p> <p><strong>Keywords:</strong> Virtual education, challenges, pandemic, COVID-19.</p> 2022-03-31T00:00:00+00:00 Copyright (c) 2022 Omar Flor, Veronica Toaza, Marlene Barragan, David Lopez Academic stress according to sociodemographic factors in university students in a period of confinement due to COVID-19 2022-04-28T11:47:26+00:00 Yelina Quispe Milagros Huarcaya Karen Cruz Brithany Mamani Nicole Almeron <p>Stress is a health problem that affects today's society, it is reflected in the degree of reaction to events or academic situations faced by the university student. The level of academic stress was analyzed according to sociodemographic factors in university students in a period of confinement due to COVID-19. 525 randomly chosen students from private and licensed universities in the city of Arequipa participated, an instrument was used to assess academic stress consisting of 21 items that measure stressors, symptoms, and coping strategies. The results show that students have a moderate academic stress level with a tendency to be severe, it´s caused by the overload of academic work, the form of evaluation, and the type of work that teachers ask for, thus affecting their health due to the presence of somatic symptoms that affect students at the biopsychosocial level.</p> <p><strong>Keywords:</strong> Academic stress, university students, sociodemographic factors.</p> 2022-03-31T17:53:21+00:00 Copyright (c) 2022 Yelina Quispe, Milagros Huarcaya, Karen Cruz, Brithany Mamani, Nicole Almeron Capítulo 7: Diseño de canaleta Parshall 2022-04-28T11:47:10+00:00 Franyelit Suárez Cristian Milton Mendoza Flores Fernando Ricardo Arteaga Valdez Cristina Johanna Toledo Toledo Fernando Demetrio Llatas Villanueva Jose Luis Zumaran Irribarren <p>I. INTRODUCTION<br>The Parshall Flume, which was invented in 1920 by R. Parshall, is mostly used in wastewater and crop supply. Utilizing equations, Parshall established dimensions that fit the design, one of the advantages is the conversion of position energy to velocity energy since in other measurement structures there are minimum energy losses in this one it does not allow sedimentation.</p> <p>The structuring of the project is adhered to by different models that define its behavior and limit its use. This is the case of an approach length of the channel entrance, which is nothing more than a primary distance for the action of the flow within the channel. Throughout history, some studies were conducted in an attempt to establish an approximate and realistic value of the length at the time of measurements, but the theories put forward were lost. Some people link this length with the narrowing of the gorge, and others suggest flow conditions before entering the flume.</p> <p>For the development of the project established with its respective objectives, the respective structuring was carried out: For the measurement, the points already established in the field will be taken with the help of a total station, GPS, to verify the respective measurements of the Parshall flume. For the calculations and the design, the points will be introduced in the civil 3D to be able to verify if the points taken are the correct ones and what distances they have between them, through this, we can apply different methods to be able to verify the design that has this Parshall flume. For the evaluation and layout of the gutter, if it is the case, we will carry out a layout in plan with the data already calculated in the office and we will evaluate the situation in which it is so that we can apply a possible solution so that a defect does not occur.</p> <p>In this report, we focus on the design and redesign of a hydraulic irrigation channel where we find a Parshall section, which has the function of measuring the flow found in that section. The measurements found in the field can be verified in the office using formulas and software to verify if the data are correct, if so we can say that it is well designed, otherwise we will look for a possible solution by doing a field study.</p> 2022-03-31T19:01:58+00:00 Copyright (c) 2022 Franyelit Suárez, Cristian Milton Mendoza Flores, Fernando Ricardo Arteaga Valdez, Cristina Johanna Toledo Toledo, Fernando Demetrio Llatas Villanueva, Jose Luis Zumaran Irribarren Rock material particle size and its correlation with the point load test index 2022-04-28T11:41:01+00:00 Patricio Feijoo Adriana Peralta Andrea Tamayo Bernardo Feijoo <p>Abstract: This work proposes the methodology to obtain a correlation between the particle size of the rock material and the point load test index (Is 50), in order to characterize the materials, present in mining projects in terms of resistance. For a correct development of mining activities, both open pit (quarries) and underground (mines), it is important to determine the compressive strength of the rocks, since, through it, geomechanical classifications are obtained, and thus calculate safety factors to define stabilization and/or fortification systems for mining operations. This work was developed on the basis of samples from a geological formation and subsequent preparation of specimens, then they were subjected to physical tests, which can be carried out without problem in the field, and finally, the respective relationships were obtained. The results are encouraging and the equations are proposed to characterize the rock and achieve the proposed objective.</p> <p><strong>Keywords:</strong> Rock, Crushing, Classification, Compression.</p> 2022-03-31T20:01:53+00:00 Copyright (c) 2022 Patricio Feijoo, Adriana Peralta, Andrea Tamayo, Bernardo Feijoo
