Published: May 2024

A diabetes mellitus (DM) é considerada uma doença crônica, mas não transmissível e vem caracterizando-se como uma epidemia mundial. A Diabetes Mellitus Gestacional (DMG) é uma doença associada ao aumento da resistência insulínica durante o período em que a mulher se encontra grávida. A presença do farmacêutico é relevante na adesão ao tratamento medicamentoso, principalmente por passar segurança à paciente e ao seu bebê. Trata-se de uma revisão integrativa da literatura (RIL). Foram encontrados 13 artigos que atenderam aos critérios de inclusão e exclusão. Conclui-se que, a presença do farmacêutico é relevante na adesão ao tratamento medicamentoso, principalmente por passar segurança à paciente e ao seu bebê; ele pode atuar na análise da prescrição médica e verificar se o medicamento prescrito não vão causar danos a ambos. Neste sentido, há necessidade de mais estudos que mostrem a presença deste profissional no acompanhamento a este tipo de paciente, monitorando os valores glicêmicos e o tratamento farmacológico.

Published: May 2024

Este estudo analisou a relação entre componentes ambientais e a transmissão de arboviroses no Território de Desenvolvimento dos Cocais - PI (2012-2019), utilizando Sistema de Informação Geográfica (SIG) para mapear variáveis, incluindo temperatura, pluviosidade, umidade relativa do ar, NDVI e NDWI. Os resultados revelaram que a variação nas médias de temperatura indicou tendências distintas, com 2016 registrando a temperatura mais alta, correlacionando-se com um aumento subsequente nas incidências de dengue, chikungunya e zika. A pluviosidade influenciou diretamente as arboviroses, sendo o aumento em 2016-2017 seguido por um aumento nas incidências. A umidade relativa do ar apresentou variações, com áreas específicas com médias mais elevadas na porção Noroeste do território. A análise de NDVI e NDWI destacou a predominância de vegetação de baixa densidade e a influência das condições climáticas. As análises de correlação Pearson revelaram relações significativas. A incidência de chikungunya correlacionou-se fortemente com a umidade relativa do ar (-0.9974, p-valor de 0.0025) enquanto a incidência cumulativa de zika associou-se muito fortemente com as médias de temperatura anual (0.9970, p-valor de 0.0029). Este estudo destaca a complexa interação entre fatores ambientais e a transmissão de arboviroses, enfatizando a importância de estratégias adaptativas de controle.

“Urban farm” – an important component in the processes of sustainable urbanization
Authors: Gil-Mastelarczyk Joanna , Kowalczyk Marta
Published: May 2024

An "urban farm", constituting an area of biologically active surface, most often intended for the cultivation of useful plants, is an important and increasingly emerging component in the creation of sustainable "new urbanization". The aim of this publication is to demonstrate that the introduction of farms into the urban fabric is a response to contemporary processes taking place in the city and has a positive impact on shaping the functional and spatial structure of cities in the context of sustainable urbanization. The intention is to systematize the types of currently emerging urban farms, in terms of functionality and structure, based on the adopted criteria for the division of forms of urban agriculture, and to present examples of the theoretical formation of urban farm facilities in relation to their type and location. The results indicate that the selection of the appropriate location, form and structure is crucial in shaping farms. The benefits demonstrated by the implementation of this type of facilities and spaces determine the quality of life in the city and the future of urban planning assumptions. As a result of the spatial concentration of cities and intensified urban and demographic processes, the establishment of urban farms is an alternative structure for the economic and ecological cultivation of plants or animal breeding. It is also one of the methods of revitalization and innovative activities using modern technological possibilities, in accordance with the principles of sustainable development
Practical use of drawing in research on the historical space of the city
Authors: Piotrowicz Dariusz
Published: May 2024

Various research methods and techniques are popularised in the literature on the theory of research on the historical space of cities. However, less attention is paid to their tools. The aim of the article is to use drawing as a tool showing the historical space of the city, which is the subject of further research. There are many drawing motives and they depend on research needs. These may be objects, streets, squares and city panoramas. By analysing historical iconographic and cartographic sources, it is possible to create an image of an unpreserved object or place using a drawing, by reconstructing their form, and present them in a wider frame by adding the surroundings. In the case of streets, these may be drawings of frontages or their perspectives seen from two directions, while for squares, they may be in the form of internal and external views. Depending on how you look at it, you can draw from a human level or from above. The article presents a documentary drawing drawn with a pen as a drawing tool to be used in the graphic method of researching the historical space of cities. Especially places that have not survived to the present day. Drawing can be an alternative to digital visualisation, which requires computer equipment and specialised software

Authors: Chinga-Caicedo Rubén Andrés , Mera-Zambrano Cinthya Jamileth , Guerra-Mera Juan Carlos
Published: May 2024

Los bloques de hormigón para la construcción de losas alivianadas es un elemento esencial en el campo de la ingeniería civil, por lo que el presente estudio busca analizar la resistencia a compresión de bloques tradicionales, los cuales están elaborados a base de chasqui, arena, cemento y agua, adicionándole cascarilla de arroz al peso de la arena, siendo este un subproducto generado del proceso de molienda de este grano cosechado en los amplios cultivos de la costa de Ecuador. La finalidad de esta investigación es determinar cómo la adición de la CA, en diferentes porcentajes, mejora la elaboración de bloques tradicionales para la construcción de losas aligeradas.
Teniendo en consideración que se cumpla con la resistencia neta mínima a la compresión simple establecida en la NTE INEN 3066, adicionando a la arena los residuos de CA en 5, 10 y 15%, para la elaboración de los bloques y proceder a la realización del respectivo ensayo, el cual debe de estar entre el rango de 1,4 – 2 MPa, (el primero normado, el segundo como resistencia estándar de la bloquera) y poder concluir si dicho elemento es apto.
De los resultados alcanzados, se observó que en cada una de las diferentes combinaciones de porcentajes adicionados, el 5 y 10% se encuentra dentro de los parámetros establecidos en la norma INEN 3066 y de la fábrica artesanal, sin embargo, el bloque con 15% de CA no muestra mayores ventajas, ubicándose fuera de los lineamientos básicos establecidos por dicha norma, concluyendo que entre mayor sea su reemplazo del material orgánico, menor será la resistencia del bloque para losas alivianadas.

Cuidados de enfermería para la prevención de úlceras por presión (UPP) en el paciente crítico según la teoría de Marjory Gordon, una revisión sistemática
Authors: Chacón-Sevillano Sonia Elizabeth , Romero-Romero Evelyn Alexandra , Rosales-Maldonado Tatiana Karina
Published: May 2024

Las úlceras por presión (UPP) son afectaciones cutáneas de la piel que representan un significativo inconveniente de salud en todo el país, ya que contribuyen a la prolongación de las estancias hospitalarias y al incremento de los precios en el régimen de salud. Su incidencia negativa en las instituciones se debe a que el 95 % de estas úlceras son evitables, lo que señala un déficit en la calidad asistencial (1). Se aborda la teoría de Marjory Gordon, como un referente para la valoración de enfermería basado en 11 patrones prácticos de salud (2). La investigación desarrollada se enfoca en realizar una revisión de la literatura científica referente a la aplicación de cuidados de enfermería basados en la teoría de Marjory Gordon en la prevención de UPP en pacientes críticos. La metodología abordó la revisión sistemática de datos en bases de información como Redalyc, Scielo, Búsqueda Libre, Dialnet y PubMed, con implementación de descriptores DECS y MESH, y parámetros de inclusión y exclusión, cuya aplicación arrojó un total de 21 investigaciones. Se destaca el trabajo de Villota porque plantea el uso de una nota de clase como herramienta pedagógica porque permite comprender cómo la teoría de Marjory Gordon sobre patrones funcionales influye en el desarrollo de actividades de enfermería tanto en la formación académica como en intervenciones de cuidado en el ámbito laboral, adicionalmente Delgado et al. mencionan que es necesario proporcionar cuidados holísticos que aborden de manera integral las necesidades del paciente para asegurar una atención de calidad en la prevención y tratamiento de las UPP. Cada resultado respalda la efectividad de esta teoría en la prevención UPP en pacientes críticos, y resaltan la importancia tanto de valoraciones exhaustivas como protocolos personalizados. Su aplicación mejora la calidad de la atención, minimiza el impacto de UPP e impulsa la salud en entornos críticos, como unidad de cuidados intensivos.
Vulneración del Principio de Proporcionalidad y la no Autoincriminación en el Procedimiento Abreviado en Ecuador
Authors: Martínez-Pérez Odette , Revelo-Ávila Esteban , Zumba-Cruz Ricardo
Published: May 2024

En Ecuador, la implementación del procedimiento abreviado estaría poniendo en duda los principios del debido proceso, específicamente el de la proporcionalidad de la pena y el de la no autoincriminación. Para ello se plantea como objetivo analizar los efectos jurídicos de la aplicación del procedimiento abreviado frente a los principios de proporcionalidad de la pena y a la no autoincriminación en el debido proceso en el sistema penal ecuatoriano. La metodología empleada fue de enfoque mixto, de modalidad documental, con un método analítico e inductivo-deductivo. Las técnicas de recopilación de datos fueron el fichaje y las encuestas. Se realizó el análisis de una sentencia de la Corte Constitucional y se consideró un análisis de caso. Se concluye que el procedimiento abreviado vulnera diversos derechos fundamentales del procesado al restringir la posibilidad de presentar pruebas que podrían desvirtuar la acusación en su contra, sin tomar en cuenta que éste debe ser considerado inocente hasta que se pruebe su culpabilidad más allá de toda duda razonable y se señalaron los diferentes cuerpos legales que avalan esta idea. Respecto al principio de proporcionalidad de la pena, genera serias preocupaciones porque la misma no se establece con base en la gravedad del delito, sino por la negociación entre fiscal y procesado. Y finalmente la autoincriminación dentro del procedimiento abreviado vulnera el debido proceso porque la confesión del acusado no es suficiente para condenarlo, ya que la Fiscalía tiene la carga de la prueba.

Published: May 2024

El presente artículo toma como eje de interés el incumplimiento de medidas de protección del derecho de las víctimas de violencia intrafamiliar en Tena-Ecuador, esto a razón de la necesidad de visibilizar la importancia de garantizar la seguridad de las personas vulneradas por el delito, y en atención al respeto de su derecho a la integridad personal y la garantía de no repetición de la infracción. Para ello, se toma como metodología el uso del enfoque cuantitativo dado el análisis de datos estadísticos proporcionados por Fiscalía del Tena sobre el incumplimiento de medidas de protección, así mismo, se empleó el método de análisis estadístico y el diseño no experimental. Los principales resultados evidenciaron que, en efecto, existe incumplimiento de las medidas de protección estipuladas en el artículo 558 del COIP, especialmente en las medidas 3 y 4 donde, incluso, ha existido solo una sentencia. De aquello, se concluye que en el Tena, las garantías de protección y prevención en materia de violencia intrafamiliar es una problemática que no ha sido resuelta por el incumplimiento de las medidas señaladas, situación que desde la realidad presentada, los miembros del núcleo familiar que se han visto afectados se hallan en indefensión

Published: May 2024

Este artículo, representa una primera fase de las acciones emprendidas por la Vicerrectoría de Docencia, de la Universidad Nacional de Costa Rica (UNA), para facilitar la integración de la Inteligencia Artificial en los procesos de enseñanza y aprendizaje. Se enfoca en promover una integración armoniosa y natural de la inteligencia artificial considerándola como parte de un proceso evolutivo, en lugar de una amenaza al quehacer docente. Las acciones emprendidas incluyen procesos de sensibilización, apertura de espacios de reflexión, formación de formadores, capacitación docente, la creación de una comunidad de aprendizaje y el establecimiento de las primeras líneas normativas. Las personas docentes participantes de las acciones formativas y de la comunidad de aprendizaje, consideran que existen oportunidades en la integración de la IA en la educación como lo son: la creación de material didáctico, personalización del aprendizaje y tutoría académica. También consideran como una amenaza la deshumanización de los procesos formativos. Este grupo de personas académicas visualiza una serie de desafíos curriculares importantes a considerar como lo es la flexibilidad curricular, la transformación del enfoque pedagógico orientado a proyectos o a investigación-acción y un elemento importante el acceso a las herramientas de IA. Además, se abordan procesos de modificación y creación de normativa institucional, junto con una estrategia para que la UNA comience a transitar una ruta en la que la inteligencia artificial se vuelva un actor más del proceso educativo. La implementación de estas medidas marca un gran paso hacia modernización y mejora continua de los procesos educativos en la universidad, evidenciando que aún hay un camino por recorrer, pero con mucha motivación y colaboración de toda la comunidad universitaria.

SARS CoV-2 PROTEINS AND HUMAN PROTEINS
Authors: Марьянович Александр Тимурович , Кормилец Дмитрий Юрьевич
Published: May 2024

Белки SARS CoV-2 представляют собой молекулы с массой от нескольких десятков до нескольких тысяч аминокислотных остатков. Существуют структурные и неструктурные белки. К первым относятся шиповый гликопротеин, или S-белок (S), малый мембранный оболочечный белок (E), мембранный белок (M) и нуклеопротеин или нуклеокапсид (N). Вторая группа состоит из 16 неструктурных белков (Nsp1-16, включая полипротеины репликазы RPP 1a и 1ab) и 10 вспомогательных факторов или белков открытой рамки считывания (ORF3a, 3b, 6, 7a, 7b, 8, 9b, 9c, 10 и 14). Белки S, E и M, расположенные снаружи и в мембране вириона, участвуют в контакте вириона с клеткой и проникновении в нее. Другие белки участвуют в захвате внутриклеточных механизмов и их использовании в собственных интересах вируса. Большинство этих белков содержат многочисленные мотивы, гомологичные человеческим белкам, в том числе таким важным, как интерлейкин-7. Возможно, эта гомология является важным фактором, позволяющим «обмануть» иммунную систему на начальных стадиях инфекции и спровоцировать аутоиммунный ответ впоследствии. Гомология белков SARS CoV-2, с одной стороны, и белков вкусовых и обонятельных рецепторов — с другой, возможно, объясняетпричины нарушения восприятия вкусовых и обонятельных раздражителей, характерного для COVID-инфекции.

SARS CoV-2 proteins are molecules with a mass of several tens to several thousand amino acid residues. There are structural and nonstructural proteins. The former include Spike glycoprotein (S), small membrane envelope protein (E), membrane protein (M), and nucleoprotein or nucleocapsid (N). The second group consists of 16 nonstructural proteins (Nsp1-16, including replicase  polyproteins RPP 1a and 1ab) and 10 accessory factors or open reading frame proteins (ORF3a, 3b, 6, 7a, 7b, 8, 9b, 9c, 10 and 14). Proteins S, E and M, located outside and in the membrane of a virion, are involved in the contact of the virion with a cell and penetration into it. Other proteins are involved in the hijacking of intracellular mechanisms and their use in the virus’s own interests. Most of these proteins contain numerous motifs that are homologous to human proteins including such important ones as Interleukin-7. Perhaps this homology is an important factor in deceiving the immune system at the initial stages of infection and provoking an autoimmune response later. The homology of SARS CoV-2 proteins on the one hand and taste and olfactory receptor proteins on the other hand may possibly explain the causes of the impaired perception of taste and olfactory stimuli characteristic of COVID infection.

Authors: LAOKULRACH Marisa , TAMPHAKDIPHANIT Jinnarat
Published: May 2024

This paper identifies the development of cryptocurrency’s regulations and influences of people’s intentions to use cryptocurrency in Thailand. The analysis of behavioral intentions to use cryptocurrency is conducted applying the unified theory of acceptance and use of technology (UTAUT) model. The study used the questionnaire survey, and applied the multiple regression analysis to analyze the influences of Thai people to use cryptocurrencies. This research categorizes the purposes of cryptocurrency into three groups including: the first purpose is investment, as people buy cryptocurrency for wealth increasing; second, it is a means of payment for goods and services; and the third purpose is collecting points and redeeming rewards, as people are able to simply compare cryptocurrency to credit card points and redeem them for rewards. Regarding the findings, social influence is the most important factor that persuades people to use cryptocurrency. The other determinants in the UTAUT model that encourage people intention to use cryptocurrency are facilitating conditions, effort expectancy, and performance expectancy.

However, there have been varying results of the predictive power of PE and PB Ratio to stock returns especially when different market conditions have been considered. This study was conducted to determine if PE and PB ratios can be used as predictors for stock market returns among financial institutions listed in Bahrain Stock Exchange. It utilized an analytical research design which made use of panel data analysis. Total samples of 19 financial institutions were included study with financial data covering the periods 2015 to 2018. The study found that both PE and PB ratio significantly predicts stock returns of financial institutions stocks in Bahrain at 0.05 level of significance. Both ratios have positive coefficients suggesting a positive association with stock returns. Finally, the study also concludes that loading PE and PB as predictor of stock returns would only generate estimate parameters that can only show cross and time fixed effects. Thus, individual time invariant variables or company and industry specific factors do not play a role in the ability of PE and PB ratios in predicting stock returns.© 2020 The Author(s).

Published: May 2024

This article examines the application of the four Ps marketing mix by micro and small-scale traders (MSTs) dealing in fresh (fruit and vegetable) produce in Kenya. The study was necessitated by the need to explain unimproved living standards of the traders despite thousands of Kenyans doing business in this sector. Survey research design was adopted, and stratified random sampling techniques were employed to draw 150 respondents from among the traders in the residential estates, and the main marketing the city of Nakuru, Kenya. Structured questionnaires were used in data collection. Descriptive statistics and regression modeling were applied in analyzing the data. The results indicate that MSTs in the produce industry in Kenya, pay attention to all the 4 Ps marketing mix, i.e., promotion, place, price and product, and, in that order of increasing importance. Yet among these strategies, price and product are the most important determinants of household income. Additionally, bigger MSTs are more likely to experience increase in household income than their smaller counter parts. Finally, the average MST in the produce industry perceives that their household income has increased because of the business. Copyright© 2020 The Author(s).

Recently, China has become the world’s second largest economy behind only the United States of America. Until 1994, China used the fixed exchange rate and dual pricing system. A sharp fall in global oil prices aggravates the global downturn. Our key data were gotten from Macrotrends expertise in economic development and exchange rates. GDP Growth rate was more fluctuating pattern (variance 0.014, standard deviation 0.122) than exchange rate (Variance 0.004, standard deviation 0.07). From 1990-2019 both variables were analyzed. That means these do not vary systematically over time. In other words, they are time invariant. Regressing two series that are non-stationary likewise, yields a spurious (or nonsense) regression. So, to check it lets check the rule of thumb. We found a Durbin Watson Statistic of 0.612 and R square of 0.117. If we look the calculated t statistic with critical values at 5% significance level only Domestic Demand shows a significant relationship (4.00 >2.756) with GDP of China. A variety of analytical studies suggest that Competitive Exchange Rate strategies are suitable for economic development. We also argued that, considering some constraints on usable policy alternatives, there are theoretical origins in a policy approach such as an ideal strategy. © 2020 The Author(s).

Authors: ADÁMEK Pavel , MEIXNEROVÁ Lucie
Published: May 2024

This paper analyses the impact of COVID-19 on selected economic indicators of the European Union to bridge these impacts "marked as triggers" of changes to business models. The logic of the focus lies in the interconnection and integration of external changes in the connection of the reaction of managerial decisions for change, adaptability, and adjustment of the business model in newly formed economic systems. Economies are affected by the effects of the ongoing pandemic as part of restrictive and health-related measures, where there is a direct link to the performance of businesses that need to adapt to ongoing changes in response to the COVID-19 pandemic. Our survey is mainly based on reviews in articles COVID-19 on business activities which enable businesses to share knowledge, decisions, and prospects including analysis of selected indicators as an industry, construction, wholesale and retail trade, and services when the Eurostat statistical data (2020b) are used. We combine the approach of mapping of literature review associated with the impact of a pandemic on business and impact analysis within the European Union on the economic indicators. Subsequently, we examine what and how businesses can do to respond quickly to the stimuli, our main focus is on business models that allow to quickly operationalise the current business situation and then take measures to create a basis for sustainability. The output is a discussion and proposals for the necessary business model shifts so that companies are resilient, flexible, capture value in the long term. For businesses looking to establish update business models during COVID-19, we recognise that hiring entirely new models maybe not feasible. We focus on viability updates business models over fully comprehensive functions after crises COVID-19. We develop managerial recommendations for the growing demand for innovation and flexibility for the resilience business model to adapt to the new changed “post COVID” business environment.Copyright© 2020 The Author(s).
