Linguistic prejudice: Situations experienced within the school context
Authors: Araujo Marcilene de Assis Alves , Araújo Ilka da Graça Baía de , Costa Domingas Ferreira , Fontenele Eslaine Ferreira Teixeira
Published: June 2023

This study aimed to investigate how linguistic prejudice manifests in the learning process of 6th, 8th, and 9th grade students in a public school in the municipality of Gurupi, TO, Brazil. The interest in this subject matter arose from the studies and discussions in Linguistics classes during the undergraduate program in Bachelor’s Degree in Languages - Portuguese/English, supported by the internship experience, where it was observed that Portuguese language instruction in schools had a traditionalist approach, centered on normative grammar as the only acceptable language variation, disregarding other linguistic varieties. Consequently, this led to language prejudice against other varieties that were strongly ignored in the formal school setting. Based on these observations, the following research question guided the study: What learning situations can be implemented to mitigate linguistic prejudice experienced by students from the 6th grade onwards in elementary school? To answer this question, a research methodology combining literature review with a field study of qualitative approach was employed, involving observation, informal conversations, focus groups, and activities aimed at innovative practices related to the subject matter. The research results were promising, providing significant contributions to the main objective of the study. They demonstrated that working with active methodologies and strategies based on discourse genres and multiliteracies positively influences the reduction of linguistic prejudice in relation to the use of formal language. This, in turn, fosters students’ development and learning.

Published: June 2023

Introduction: Parasitic diseases, including helminth infections, are among the neglected tropical diseases and represent a serious public health issue in emerging countries such as Brazil. Several factors such as lack of basic sanitation, poor hygiene conditions, and lack of awareness about the subject can be the cause of the problem. Objectives: The purpose of this project was to carry out an extension action aimed at raising awareness about parasitic diseases, specifically targeting students in the lower secondary education level. Methodology: Due to the prevalence of parasitic infections among school-age children, the extension project on the theme of "parasitic diseases" was developed in a primary school in the municipality of Formiga, Minas Gerais. The project involved students from the 6th to 9th grades. The activity was carried out in two stages: in the first stage, Biomedicine students from UNIFOR gave an informative lecture using audiovisual resources about the main parasitic infections in the region. In the second stage, preserved specimens of worms and videos showing live parasites were presented. Results: The elementary school students remained attentive and curious throughout the entire presentation, and at the same time, they were also somewhat apprehensive when they had the opportunity to see the parasites beyond the screens. This experience provided them with valuable knowledge that they can share with their friends and family, especially regarding the prevention of intestinal parasitic infections. Conclusion: This project provided all participants with relevant scientific knowledge about parasitic infections, creating a network for spreading awareness about the subject to more people. In this way, the extension activity contributed to the development of more conscious and informed citizens regarding the topic at hand, potentially assisting in the reduction of local cases of parasitic infections. For the supervising undergraduate students, the activity offered scientific deepening about parasitic infections, as well as a greater understanding of the socioeconomic and sanitary issues that affect the community at large.

Authors: Leme Carolina Carvalho , Monteiro Leonardo M. , Gonçalves Joana C. S.
Published: June 2023

The compact apartments in the city of São Paulo have been growing significantly since 2013, driven by the economic, social, urban and demographic transformations of the recent decades. In 2021, the micro-apartments with less than 45m² accounted for 76% of the total residential launches in the city of São Paulo, with 58% between 45m² and 30m². The high representation of micro-apartments in the current real estate situation in São Paulo emphasizes the importance of studies focused on these new housing models. The objective of the article is to verify the thermal and luminous performance of open-plan micro-apartments produced between 2011 and 2017 in the city of São Paulo. The method is experimental based on empirical surveys of thermal and light variables from five case studies. The measurement results were comparatively analyzed from design and environmental assessments, allowing to investigate issues related to the thermal and luminous comfort of the user of the case studies. The results indicated the low environmental quality of the evaluated micro-apartments, with at least 45% of the time in cold discomfort during the winter and only 60% of IDU in the year (useful daylight illuminances: 300lux –3000lux).

Published: June 2023

Dysphagia is frequent in the elderly population, especially in individuals with COVID-19. The aim of this integrative review was to elucidate the connection between dysphagia and COVID-19 in the elderly, focusing on the implications arising from it and associated comorbidities. Methods: A comprehensive search using the PICO strategy was conducted in six databases: PubMed/Medline, Embase, LILACS, Scopus, Web of Science, and SpeechBITE. Articles published between 2019 and 2022, without language restrictions, involving participants aged 60 years or older diagnosed with COVID-19 and exhibiting signs/symptoms of dysphagia were included. Results: The analysis included 42 articles, with the majority being case reports. The sample involved 298 older adults, with a mean age of 70.5 years and a predominance of males. The implications of dysphagia included the need for alternative feeding, laryngotracheal penetration/aspiration, adjustment in diet consistency, aspiration pneumonia and dysfunction in the orofacial and pharyngeal muscles. Pre-existing comorbidities associated with COVID-19 were identified, such as Guillain-Barré Syndrome, Myasthenia Gravis, Hypertension and Diabetes Mellitus. Conclusion: This integrative review highlights several implications of dysphagia in the elderly with COVID-19, with alternative feeding being the most mentioned. However, less than half of the studies described the implications observed among patients. The findings highlight the need for future investigations and development of appropriate therapeutic strategies aimed at improving quality of life and preventing complications in this population. Identification of the implications and comorbidities associated with dysphagia may assist in the development of more effective and safer clinical management approaches.

Published: June 2023

Prader Willi Syndrome is a genetic disease caused by the lack of expression of genes on chromosome 15 (chromosomal region 15q11-q13). In 1956 it was described for the first time by Prader, Labhart and Willi. It is a complex neurodevelopmental disorder, regardless of ethnicity or sex. The main features of the syndrome in the neonate are hypotonia, hypogonadism, difficulty in sucking the breast and facial dysmorphisms. PWS has two different clinical nutritional phases. The first begins at birth, characterized by difficulties in latching on to the breast due to low suction. In the second phase, from the age of 2, the child has excessive hunger that leads to progressive obesity, if not controlled by the diet. The diagnosis of PWS is made by non-invasive genetic testing. DNA methylation analysis detects the condition more than 99% of the time and is therefore considered the first-line genetic test. This study aimed to analyze the importance of early diagnosis in the pediatric population, based on a case report that occurred in a maternity hospital in the Planalto Norte Catarinense. The study was qualitative in nature with a descriptive and retrospective orientation. Data collection was performed from the patient's chart. In the development of this analysis, the importance of early diagnosis for rapid intervention and improvement of prognosis and quality of life of these patients became evident. Early diagnosis and appropriate care are crucial for the baby's outcome, as it ensures comprehensive care to prevent obesity and stimulation of cognitive and adaptive skills.

Published: June 2023

El trabajo presenta una lectura general del posestructuralismo y lo describe como unconjunto heterogéneo de teorizaciones acerca de lo social, lo político y lo subjetivoque tuvieron al estructuralismo, al freudismo y al marxismo como referencias complejas.Proponemos caracterizar al posestructuralismo por sus operaciones de “atravesamiento” de estas referencias y distinguir en el desarrollo de sus investigaciones dos grandes etapas: una vinculada a la afirmación de la diferencia radical y la crítica a las concepciones totalizantes de sistema, y la otra ligada a la reconceptualización de los sistemas como multiplicidades o no-todos. En este trabajo, examinaremos principalmente la primera etapa, y solo esbozaremos algunos elementos claves para la comprensión de la segunda.

Published: June 2023

O estudo sobre a relação comércio e cidade constitui-se como base para explicar as configurações espaciais da cidade contemporânea, principalmente as cidades do Nordeste. Sendo assim, objetivamos com este artigo discutir como o surgimento e reprodução de formas comerciais de grande e pequeno capital explica a dinâmica das cidades nordestinas e a redefinição dos seus papeis no contexto urbano-regional. Para isso, serão realizados levantamentos teóricos e de dados primários e secundários que sirvam de embasamento para as reflexões construídas. Dessa forma, considera-se, com este estudo, que as metamorfoses e coexistências ocorridas no âmbito da atividade comercial dão base para compreensão da realidade das mais diversas cidades, sejam elas pequenas, médias e até mesmo das metrópoles nordestinas. Ao mesmo tempo, a multiplicação e expansão de novas formas comerciais e a ressignificação de formas comerciais tradicionais são responsáveis pela conformação de estruturas urbanas pautadas na lógica de múltiplas áreas centrais e centralidades, como ocorre em Campina Grande, cidade média localizada no interior do Nordeste brasileiro.

Neste contexto, tanto a modelagem matemática quanto a modelagem computacional necessitam de uma descrição acurada que permita que esses modelos sejam compartilhados, reutilizados e simulados tal como foram formulados por seus criadores. Neste artigo, apresentamos a Cell Component Ontology CelO, uma ontologia expressa em OWL-DL, que captura tanto a estrutura do modelo de uma célula quanto as propriedades dos seus componentes funcionais. A ontologia CelO é utilizada em uma arquitetura orientada a serviços para descrever, realizar inferências e consultar os modelos CellML. O objetivo principal da arquitetura é facilitar o reuso e a composição dos componentes existentes e permitir a validação semântica de novos modelos.
Recovering and checking software architectural properties based on execution tree analysis
Authors: Braga Thiago H. , Maia Marcelo de A. , Bigonha Roberto da S.
Published: June 2023

The specification of the software architecture is an important artifact produced during software design. However, traditional specification techniques do not provide support for guaranteeing that architectural properties of the specification are valid for the implemented software. We propose an approach to recover and specify architectural properties based on execution constraints. The proposed approach is based on specifying constraints as queries in execution trees of software systems. The constraints are generated as annotations and verified against the implementation with a dynamic verifier. We have implemented a tool for Java systems and we argue that our approach presents some benefits over similar ones.

An Empirical Investigation of Value at Risk (VaR) Forecasting Based on Range-Based Conditional Volatility Models
Authors: Padmakumari Lakshmi , Shaik Muneer
Published: June 2023

Value at Risk (VaR) is a widely used measure of market risk. Precision in the estimation of volatility leads to accurate VaR forecasts. As volatility is time-varying and has a clustering effect, GARCH class of volatility models is helpful in modeling volatility more precisely. Studies have also shown that range-based volatility estimates are more efficient than traditional models that use only closing prices. Therefore, this study uses the GARCH family of volatility models to model and forecast VaR. The study compares conventional models that use closing prices alone, like GARCH and TARCH, with range-based models like RGARCH and RTARCH models, where the range defined as daily high price minus low price is introduced as an exogenous variable, to explore if the latter provides better predictive accuracy. All the models are back-tested using the Kupiec (1995) unconditional coverage and Christoffersen (1998) conditional coverage tests. The data period in the study ranges from 2003-2021, and we consider five BRICS indices and three major developed economies, namely, the USA, the UK, and Germany. An empirical investigation shows that range-based models do a better job in VaR forecasting as it has more information content than daily closing prices, thereby giving more accurate VaR estimates. The study hopes this finding will greatly help stakeholders like financial institutions, regulators, and practitioners in more effective market risk management.

Adaptive integer arithmetic coding with RLE-transform
Authors: Barannik V. , Havrylov D. , Hurzhii P. , Kolesnyk V. , Tsimura Y.
Published: June 2023

The paper proposes a method of multilevel selective processing to increase the availability of information about critical infrastructure objects with a given level of reliability and confidentiality. This technology is based on the identification of key information at several stages of processing and adaptation of the RLE algorithm and integral arithmetic coding into a new input data structure.

Thus, the last stage of processing video data by the proposed approach is considered, which is aimed at reducing the volume with the following features: further development of the method of linearization of two-dimensional transforms based on zig-zag scanning is obtained.

The differences of the method lie in carrying out the vector intertransform zigzag linearization taking into account the selection of spectral components, which is defined as complementary. For the first time, a method of decomposition of a linearized transform based on the definition of a threshold has been developed.

Characteristic features of the method: the threshold is found taking into account the presence in the group of different types of transformants to determine the total uneven number of non-equilibrium complementary components; the integral arithmetic coding has been improved based on taking into account the frequencies of dictionary elements (two-dictionary integral arithmetic coding).

Distinctive features of the method: determination of the current code components by the decomposed working interval, depending on the capacity of the dictionaries of significant elements and the number of repetitions. This allows additionally taking into account the statistical features of the components of the RLE-structured linearized transform and reducing the length of the arithmetic code; For the first time, a transformant compression technology was created based on the reduction of various types of redundancy in groups of transformants.

Characteristic features of the technology: RLE-structuring of the non-uniform complementary part of the group of transforms after their vector linearization and decomposing; the formation of two arithmetic codes according to two dictionary principles of uneven division of the working interval, depending on the type of transformants in the group.
Tkachenko Methodology for building radio relay lines based on the use of geospatial information
Authors: Kovalenko І. , Masesov M. , Draglyuk O. , Tkachenko A.
Published: June 2023

When planning and organizing communication using modern military digital radios, a crucial and relevant task is to ensure the maximum possible communication range while providing the necessary speed and quality of information transmission. The main factors determining the possible communication range of modern military digital radios, in addition to their characteristics, are the terrain relief, buildings, and vegetation. Additionally, existing height objects in the area, such as communication operator towers, can be used to organize radio relay communication.

An analysis showed that existing methods and specialized software can be used for certain calculations of signal levels, but they do not always take into account all necessary technical parameters of radio equipment and additional geospatial information. Moreover, the existing software is not designed to construct multi-interval radio relay lines while considering additional geospatial data. In constructing radio relay lines, there is often a situation where one interval cannot provide communication with the required quality. This situation calls for planning a radio relay line using relay stations. The choice of the location of relay stations depends on many factors, including the possibility of establishing communication, minimizing the number of relays, geospatial information regarding the terrain relief, and the presence of the necessary infrastructure (buildings, power supply, anchor points, towers, etc.) in the area.

The article proposes a methodology for constructing radio relay communication lines based on calculations of signal levels while considering geospatial data. This methodology allows analyzing individual radio relay intervals for constructing multi-interval radio relay lines. The software implementation of the developed methodology allows creating software for calculating radio relay lines with the necessary input data and geospatial information regarding the terrain.
The method of calculating the design parameters of a collinear serial antenna using the dispersion characteristics of the retarding system
Authors: Radzivilov H. , Ilyinov M. , Khomenko P.
Published: June 2023

The paper presents a technique for analyzing the electrical characteristics of series-type collinear antennas made according to the Franklin scheme, which are intended for use in radio communication systems with moving objects as basic or subscriber antenna-feeder devices. Collinear antennas belong to omnidirectional type antennas and allow to significantly increase the amplification factor in comparison with already existing types of antennas of a similar type, which is what attracts antenna technology developers today.

The main element of a series-type collinear antenna is a phase-shifting device that determines both the performance of the antenna and its electrical characteristics. The most widely used phase-shifting devices were inductive chokes – a section of conductor of a certain length rolled into a spiral.

The proposed engineering method of calculating the parameters of the inductive choke allows you to quickly and accurately adjust its characteristics with the calculation of the necessary phase shift. This approach takes into account the physical parameters of the conductor material and the geometry of the spiral conductor, which greatly simplifies the engineering process of developing collinear antennas. The obtained results of simulation of electrical characteristics confirm the effectiveness of the proposed method.

A significant increase in the amplification factor compared to the existing types of antennas and compliance of the electrical characteristics with the specified parameters was revealed. The work has an important contribution to the development of antenna technology and has practical application in radio communication systems with moving objects. The proposed method of calculating the parameters of the inductive choke can be used by antenna developers to increase the productivity and efficiency of their radio communication system.
Model for calculating quantitative indicators for assessing the efficiency of protecting a critical infrastructure object from impacts of unmanned aviation complexes
Authors: Radchenko M. , Shapoval V. , Tereshchenko T. , Dykyi О.
Published: June 2023

The growing potential for the use of unmanned systems, which are designed to perform combat missions in the air, on the ground, on/under water than ever before, leads to an increase in threats to the defense landscape of defense forces. This is the reason for the rapid growth of interest in technologies that neutralize threats of this type. For the party that protects a critical object from an air attack by an unmanned aircraft complex (or group), the issue of guaranteed effectiveness or economic proportionality of methods of protection against low-cost attacks that can be carried out by such complexes is always relevant. The answer to this question begins with the availability of a device for calculating quantitative indicators for evaluating the effectiveness of protecting a critical infrastructure object from an air attack.

The process of functioning of a critical infrastructure object, which includes a deployed protection system, a control point and subsystems with critical equipment, through which the general purpose of this object is carried out, is proposed to be described by analogy with the model of the process of functioning of a renewable system with limited element reliability. In order to quantitatively assess the effectiveness of the protection of a critical infrastructure object from air attacks by unmanned aerial systems, it is proposed to take a comprehensive indicator of the reliability of the functioning of the renewable system, which consists of the following components: the readiness factor, the vulnerability factor and the protection from air attacks. Expressions of calculation formulas are given in accordance with the proposed process description model.

The obtained indicators for the quantitative assessment of the effectiveness of the protection of a critical infrastructure object from air attacks will be converted into specific proposals for persons who make decisions on the selection of the necessary types of countermeasures against unmanned aircraft systems for the expansion of the defense system, and which are required for the justification of financial and economic costs when overcoming this type of threat.

Published: June 2023

The article analyzes explosive objects of various types and provides their characteristics. Their unmasking feature is the material of the main part (casing), it is noted that high-explosive mines are characterized by the use of a plastic casing, for fragmentation mines – a metal casing, and the most difficult to detect are mines with a plastic casing. Methods of detecting explosive objects compared to those currently used in Ukraine are considered. Unfortunately, given the scale of mined areas, they are ineffective, so it is obviously necessary to develop more effective solutions for their detection and neutralization based on modern achievements of technical progress. Foreign countries have developed and use modern mobile robotic complexes for demining based on unmanned aerial vehicles with various types of sensors installed on them.

It is expedient to create a universal detection system that can be deployed on any helicopter-type unmanned aerial vehicle (quadcopter, multicopter), on which several detection sensors are installed at the same time for the purpose of reconnaissance of the mine situation, detection of mines and their remote destruction. The article proposes the synthesis of a system for detecting explosive objects based on an unmanned aerial vehicle with a thermal imager installed on it, in combination with a metal detector and a manipulator with explosives for remote demining. The parameters of detection of explosive objects, the type of sensor sensors and the main functions of the system are considered. The algorithm of actions of the operator of the system for detecting explosive objects is proposed.
Probabilistic Graphical Model for Sizing Assessment in Ultrasonic Testing in Dissimilar Metal Weld
Authors:   VTT Technical Research Centre of Finland, Siddig Mohammed
Published: June 2023

This work investigates an approach for evaluating the uncertainty associated with flaw sizing in Ultrasonic Testing in nuclear inspections using Bayesian Belief Networks (BBN). BBN graphically represents the probabilistic relationship between the sizing accuracy and some of the variables that cause its deviation.

The data for BBN training was collected from sizing information of Round-Robin trials reported in the literature and supplemented with sizing results obtained using the Ultrasonic Testing module of CIVA Non-Destructive Evaluation software. The test specimen used in the Round-Robin exercise and simulations was a dissimilar metal welded pipe. Given the available data, the variables considered causing sizing inaccuracy are the flaw’s actual depth, tilt angle, and position in relation to inner and outer surfaces.
Visualita e drammatizzazione
Authors: Spuntarelli Chiara ,   Instituto Patristico Augustinianum
Published: June 2023

This contribution aims to investigate how Chrysostom’s rhetoric, which is highly pedagogical, is built on the interweaving of visualization and dramatization in order to actualize and materialize what is invisible. The analysis is based in particular on his panegyrical production, which reveal how he constructs a rhetoric of images grounded in the synaesthetic relationship between sight, hearing, touch, and smell. It focuses on the notions of phantasia and enargeia, and insists on a parallelism between the cult of relics and devotion to images which makes it possible to read Chrysostom’s panegyrics, which were proclaimed on pilgrimage at local martyria, with others by him produced for use on the much longer pilgrimages to the Holy Land. The distinctive features of both are visual.

Maqāṣid Al-Zakāh and Poverty Alleviation: A Case Study on the Western Cape Muslims
Authors: Abdul-Jabaar M. Wahib
Published: June 2023

This article endeavours to explain how the Muslim practice of zakāh (almsgiving) is a viable model  for poverty alleviation in the Western Cape. This paper will briefly examine the origin and history  of zakāh, how it has developed over time, the relevant Sharī’ah aspects, its rulings, and the  spiritual rewards relating to the practice, including those liable to pay and who are eligible to  receive zakāh. A selection of the organisations in the Western Cape and their principal objectives  to alleviate poverty will also be discussed. A holistic view will be presented explaining the  epistemology of poverty. The consequences of poverty will be described, and then an assessment of  what the State is doing regarding the reduction or alleviation of poverty in South Africa will be  undertaken. This paper will also highlight both historical and contemporary views on the issue of  zakāh. The conclusion provides some solutions, recommendations, and alternatives that could improve  Muslim communities socially, economically, and spiritually.
Investigating the Experience of Muslim Widows in Cape Town: A Maqāṣid al-Sharīʿah Approach
Authors: Samodien Ibtesiam , Al-Sowaidi Belqes
Published: June 2023

Injustice and violence are rife in Cape Town, particularly against women who are disproportionately impacted by such issues. The present study investigates the experiences of Muslim widows living in Cape Town and highlights the unfair treatment this group often receives, indicating a critical need for social interventions. This study is qualitative in nature which involved face-to-face interviews with ten Muslim widows. It adopts the Maqāṣid al-Sharīʿah approach in navigating the experiences of these ten Capetonian widows and draws on the ideas of Al-Ghazālī (1998); Al-Shāțibī (1992) and Al-Qarāḍawi (2005) who offer an understanding of the maṣlaḥah as a fundamental organising principle of the Sharīʿah in all aspects of life. This study concludes that none of the participants received fair treatment, as outlined by the objectives of the Sharīʿah.

Principio de tutelaridad protección jurídica preferente ante el menoscabo al derecho del trabajo
Authors: López Herrera Josefa Eufemia
Published: June 2023

El menoscabo al derecho de trabajo ha sido un problema social en Guatemala, que ha afectado a trabajadores desde siglos pasados, fueron objeto de torturas y esclavitud, en el presente siglo la esclavitud ya no es muy notoria, gracias a la protección de derechos humanos; aun así existe abuso de patrono hacía el trabajador, no paga un salario justo, no pagar la indemnización es otro factor para demandar al patrono ante Juzgado de Trabajo, agotada la vía administrativa entra en conflicto laboral con el patrono ante un Juzgado jurisdiccional, que conoce y resuelve, basado en ley vigente, con la protección jurídica preferente, ello despierta el interés de analizar profundamente los derechos humanos, principios del derecho, que no se viole el debido proceso; las normas vigentes en materia laboral aportan elementos para el bien común de las partes, tomando el Principio de tutelaridad que asiste a todos los trabajadores basado en la C.P.R.G, 4, 44, 46, 101-117, leyes locales e internacionales, si no se aplica la justicia se ve afectada la esfera jurídica en el presente estudio se analizó al derecho comparado como instrumento legal que compara características de diferentes sistemas jurídicos que se aplican para solucionar de forma justa los problemas laborales, normas que favorecen a Guatemala: convención sobre derechos del niño, Pacto San José, convención de viena, la OIT, DUDH con similitud a derechos civiles en materia jurídica internacional para propiciar un trabajo digno, para el bien común, la armonía y la paz de la sociedad.
Sistemas de conocimiento ágil en la política pública desde la integración del estado y la sociedad civil a partir de la participación ciudadana
Authors: Hussein Dasuki Karim , Molinares Carmen Margarita
Published: June 2023

El siguiente texto, tiene como propósito presentar un análisis reflexivo sobre la conceptualización e implementación de la política pública como un mecanismo de participación ciudadana, la reflexión teórica práctica que se abordará, se ubica en el contexto de la revisión bibliográfica, la cual incorpora varios aspectos conceptuales y metodológicos novedosos relacionados con metodologías sistemáticas que han emergido en los últimos año. En esta revisión teórico/práctica se parte del concepto de interrelación de actores (públicos, privados y sociedad civil) como entes primordiales del sistema social, abordando la experiencia que ha tenido Colombia en la identificación y comprensión de los elementos sociales, que constituyen el diseño de la ruta de la política pública. Como resultado se generaron las herramientas de ejecución del agile mindset aplicado a la construcción de políticas públicas. En la actualidad, se han desarrollado metodologías sistemáticas que permiten un enfoque más ágil en la construcción de políticas públicas, lo que puede resultar en una mayor eficiencia y eficacia en la implementación de estas políticas. En este contexto, el agile mindset ha emergido como una herramienta valiosa en la construcción de políticas públicas. Esta metodología se basa en una mentalidad ágil y flexible que se enfoca en la entrega de valor al cliente o usuario final. La metodología agile mindset se centra en la colaboración, la iteración y el enfoque en el usuario final, lo que permite a los equipos de política pública adaptarse rápidamente a los cambios y necesidades del entorno.
