There are innumerable advances that involve the intensive use of technology to correlate the data necessary for decision making. In this article, an estimate of the presence of diarrhea in children due to Rotavirus is carried out against climatic conditions through the Bayesian factor that includes a Pearson correlation, where the posterior distribution is characterized and the Bayes factor is estimated. For this purpose, a series of temporal climatic data and data series of sick patients with rotavirus diarrhea are analyzed. The study was carried out in the municipality of Pinar del Río, in the period from November 2018 to May 2019. The population susceptible to the disease is 516 patients, for a sample of 210 children, aged 1 month from birth to 5 years of age and who were hospitalized at the Pepe Portilla Pediatric Hospital in the province of Pinar del Río. The results obtained through a Pearson linear correlation is that there is a significant correlation well below the P value and it is argued in this regard that, as there is a greater number of precipitations, the greater the number of patients with rotavirus diarrhea. Subsequently, the Bayes Factor is calculated to corroborate what has been raised; obtaining a value equal to 0.124</p> Neilys González Benítez Carlos Alberto Miranda Sierra Elba Cruz Rodríguez Cristi Darelis Roig Contreras Misladys Rodríguez Ortega Copyright (c) 2021 Neilys González Benítez, Carlos Alberto Miranda Sierra, Elba Cruz Rodríguez, Cristi Darelis Roig Contreras, Misladys Rodríguez Ortega https://creativecommons.org/licenses/by-nc-nd/4.0 2021-09-30 2021-09-30 5 2 1 14 10.46480/esj.5.2.54 Management and monitoring of patients in their diet’s nutrition using a website https://journals.gdeon.org/index.php/esj/article/view/106 <p><span style="caret-color: #000000; color: #000000; font-family: -webkit-standard; font-size: medium; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;">Currently, most of the world's population have different pathologies that prevent them from being active in their daily activities, so nutrition professionals oversee advising a nutritious and healthy diet, but to be able to do so, they require enough resources such as time to carry out the different non-automated processes where the information of the patients is taken through a medical record, which contains anthropometric, biochemical, clinical and dietary data. This work aims to implement a web system that allows for managing and monitoring patients' nutritional diets. We applied the agile project management methodology Extreme Programming (XP) to maintain a proper organization in the implementation of the software product. Also, ISO/IEC25010 was used to measure usability and performance efficiency. Regarding the methods used, descriptive statistics were used, non-parametric statistics using the Tukey test. As a result of the performance efficiency, 86% of the performance was obtained in the processes carried out by the nutritionist, allowing them to reduce 53.86 minutes in patient care. On the other hand, the usability level was reached at 94%. It is concluded with a confidence level of 95% and a margin of error of 5%, there is equality of the sub-characteristics of usability since it has made it possible to speed up the process of nutritional assessment of patients.</span></p> Gina Quichimbo Pereira Klever Pardo Jiménez Gloria Arcos-Medina Miriam Avila Pesantez Copyright (c) 2021 Gina Verónica Quichimbo Pereira https://creativecommons.org/licenses/by-nc-nd/4.0 2021-09-30 2021-09-30 5 2 15 30 10.46480/esj.5.2.106 Predicting the Effectiveness of Rapid Tests Performed to Patients with COVID-19 through Linear Regression and Random Forest https://journals.gdeon.org/index.php/esj/article/view/108 <p>The rapid spread of SARS-CoV2 (COVID-19) has caused a collapse of health systems worldwide, so a strategy to control the spread is the timely detection of the virus through rapid tests, which allows acting and thus giving a timely treatment that reduces its spread. With the help of artificial intelligence techniques, within the subfield of machine learning or machine learning, there have been significant advances that allow speeding up the analysis of large volumes of data. This study aims to determine the effectiveness of rapid tests in detecting covid-19, using machine learning, applying a methodology that involves the creation of linear regression and Random Forest models with the Python programming language. In the methodology used, the models were created, which were then defined and trained, and after performing the tests and predictions, the validation metrics determined the precision and effectiveness of these models. From the results obtained, it is concluded that the random forest model is good since it provided a precision of 61%, but with the linear regression model, it was determined that it has a precision level of approximately 90%, so finally, with these results, health professionals will be able to make reliable predictions regarding the effectiveness of rapid tests as a mechanism that will help to quickly detect the presence of the virus and thus reduce the spread of the virus.</p> Darwin Patiño Pérez Celia Munive Mora Lorenzo Cevallos-Torres Miguel Botto-Tobar Copyright (c) 2021 DARWIN PATINO https://creativecommons.org/licenses/by-nc-nd/4.0 2021-09-30 2021-09-30 5 2 31 43 10.46480/esj.5.2.108 Family support to the teacher in the care of children with learning disabilities in mathematics https://journals.gdeon.org/index.php/esj/article/view/109 <p><span style="caret-color: #000000; color: #000000; font-family: -webkit-standard; font-size: medium; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;">Currently, learning problems have become a critical point in basic primary and high school education. Even though in developed countries this type of problem has been investigated since the 1960s, in Latin America this topic is relatively recent. Dyslexia is the best known, but there are also disorders in&nbsp;mathematics, specifically dyscalculia, which is not generally known. Research indicates that most people who suffer from it are not diagnosed. Many parents are unaware that their children suffer from some type of learning problem, since many do not present obvious signs. This hinders the development of the child since early intervention has a beneficial impact on cognitive development. This work is aimed at investigating how family support affects the attention to learning problems in&nbsp;mathematics in fifth-year basic general education students; for this, surveys were conducted for parents, tutors, and teachers, an interview for the institution's DECE staff, and observation guides for students. A significant sample of the groups was chosen, the collected data was tabulated and analyzed, finding that there is no knowledge among most of the parents about this problem, although tutors and teachers have medium knowledge about it, and the institution has tools to help students.</span></p> Haydeé Bajaña Salazar Copyright (c) 2021 Haydeé Bajaña Salazar https://creativecommons.org/licenses/by-nc-nd/4.0 2021-09-30 2021-09-30 5 2 44 59 10.46480/esj.5.2.109 Novel method for analysis of electrical faults in electronic boards us-ing the GASE matrix in the electronics industry of Mexicali https://journals.gdeon.org/index.php/esj/article/view/110 <p><span style="caret-color: #000000; color: #000000; font-family: -webkit-standard; font-size: medium; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;">The presence of electrical faults in electronic boards manufactured in the electronics industry causes great economic losses even with sophisticated equipment and machines in the manufacturing areas. The objective of this work was the application of the GASE matrix (Guide, Analysis, Solution and Evaluation), coupled with the automated detection system of electronic components that are used in cellular telephony. The study consisted of three phases: (1) evaluation of the main causes of the presence of electrical failures with the Ishikawa diagram, (2) design and application of the GASE matrix to detect defective electronic boards and (3) analysis of operability of electronics manufactured as new market products of the telecommunications industry. The investigation lasted from 2018 to 2019. With the Ishikawa diagram analysis, the main causes were determined, the most relevant being the lack of training of workers, either for manual or automated activities.</span></p> Ismael Mendoza Muñoz Mildrend Ivett Montoya Reyes Juan Ceballos Corral Olivia Yessenia Vargas Bernal Gustavo Lopez Padilla Copyright (c) 2021 Gustavo Lopez https://creativecommons.org/licenses/by-nc-nd/4.0 2021-09-30 2021-09-30 5 2 60 67 10.46480/esj.5.2.110 Vulnerability mitigation in an ISP core network: A case study https://journals.gdeon.org/index.php/esj/article/view/117 <p><span style="caret-color: #000000; color: #000000; font-family: -webkit-standard; font-size: medium; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;">Cybersecurity incidents in ISP (Internet Service Provider) infrastructure have grown significantly and it is necessary to identify vulnerabilities that need immediate protection. In this environment, the firewall can filter data packets, analyzing the headers and deciding about the routing of the packet based on the established rules. This device is very essential in an ISP network because it mitigates the vulnerabilities coming from the network, maintaining a higher degree of computer security for your internal network, thus guaranteeing the availability, integrity, and confidentiality of the information. In the case study, a Mikrotik brand infrastructure was selected with a proprietary operating system called RouterOS, which will function as a core router, where the security rules will be applied to your firewall for each type of attack that will be generated against the router. , whether they are internal or external attacks on the network, avoiding causing serious security failures such as being the victim of a DoS (Denial of Service) attack, brute force attacks, etc. As a result, a 50% decrease in CPU consumption was obtained in each attack generated, thus achieving the proper functioning of the network infrastructure and guaranteeing stability and availability of the communications network.</span></p> Byron Mauricio Palate Diego Avila-Pesantez Copyright (c) 2021 Diego Avila-Pesantez https://creativecommons.org/licenses/by-nc-nd/4.0 2021-09-30 2021-09-30 5 2 68 82 10.46480/esj.5.2.117 Proposal for improvement to reduce waiting times by means of a Mathematical-Computational Model of Waiting Lines https://journals.gdeon.org/index.php/esj/article/view/124 <p><span lang="EN-US">In this article, a solution is proposed through a mathematical model applied to the urban taxi service that goes to “Cantón Durán”, from the city of Guayaquil. Applying a queuing theory model. It is determined whether the way in which the taxi service is currently offered to users is the most indicated with respect to the time that passengers must wait from the moment they arrive at the place of boarding of the taxis until the moment of their departure. By using the mathematical model of queuing theory, which simulates the process that passengers have to go through to take a taxi, it is intended to reduce the waiting times to take the taxi service of each person. also determine the number of taxis that should provide the service depending on the time, day of the week, and traffic, which is a determining factor for the travel times of each unit.</span></p> Héctor R.

The objective of this research is to review the steps taken by the different countries, in order to minimize the impact they generate, through a descriptive analysis and a documentary compilation of the years 2015 - 2020; taking as a sample the different investigations through 29 scientific articles, 12 of these from the scientific base of Scopus and 17 from ScienceDirect, which date from supervisory political measures, processing plants, incentives to recycling companies, reuse of waste with different methodologies, etc., highlighting the ecological importance that includes reusing waste through these steps that are for the good of the environment. From the systematic review it is concluded that the use of processing plants with Advanced Dry Recovery (ADR) technologies and the Heating Air Classification System (HAS) is an effective way to crush concrete waste and convert it into recycled aggregates, turning them into reusable material for construction purposes.</span></p> Sócrates Pedro Muñoz Pérez Marco Junior Bayona Reyes Julio Ricardo Yovera Santisteban Copyright (c) 2021 Sócrates Muñoz, Marco Junior Bayona Reyes, Julio Ricardo Yovera Santisteban https://creativecommons.org/licenses/by-nc-nd/4.0 2021-09-30 2021-09-30 5 2 100 106 10.46480/esj.5.2.90 The Influence of RCD in replacement of aggregates for the elaboration of concrete: A literature review https://journals.gdeon.org/index.php/esj/article/view/111 <p>It is important to reduce the environmental impacts caused by making concrete. The use of recycled aggregates in place of natural aggregates is an option that can make concrete a less polluting material while also lowering costs and making the building cheaper. However, the production of concrete with construction and demolition residues (RCD) is faced with finding an optimal design to achieve the best mechanical performance. Therefore, this document aims to carry out a selection and systematic analysis of scientific articles to evaluate the current research scenario on the influence of RCD on the replacement of aggregates for concrete. For which 55 documents extracted from databases such as: Scopus, Science Direct, and Scielo were reviewed, considering the publications that were between the years 2015 and 2021. The results have shown that it is not convenient to totally replace the natural aggregates with RCD, because the higher the replacement rate of the aggregates, without any additional compound, the more affected the mechanical properties of the final concrete will be. In conclusion, it can be stated that the use of these residues is economically beneficial, taking into account that they should be used in replacement percentages not greater than 50% and preferably only for fine aggregates.</p> Sócrates Pedro Muñoz Pérez Diego Mauricio Díaz Sánchez Edinson Enrique Gamarra Capuñay Josef Alexander Chaname Bustamante Copyright (c) 2021 Sócrates Muñoz, Diego Mauricio Díaz Sánchez, Edinson Enrique Gamarra Capuñay, Josef Alexander Chaname Bustamante https://creativecommons.org/licenses/by-nc-nd/4.0 2021-09-30 2021-09-30 5 2 107 120 10.46480/esj.5.2.111
