Abstract Textile sludge is a waste from the effluent treatment of textile laundries and its incorporation into alternative materials has been proposed as a possibility for its disposal. A systematic search was carried out in literature from this perspective, aiming to observe concentrations of waste material and its preparation, matrices used, technological performance and immobilization of textile waste. The matrices used were mortars, concretes and ceramic bricks, in general, deleterious effects were observed on mechanical characteristics of the materials produced. In concrete and mortars, the fineness had an impact on increase in water demand, which increased mixtures porosity; and organic matter and heavy metals, in cement hydration. Recent studies therefore proposed waste material pre-treatment as a favorable alternative. Increases in porosity also occurred in ceramic bricks, however, due to high organic matter content. Regarding waste immobilization, cementitious materials showed satisfactory performance; ceramic bricks, on the other hand, obtained some results outside the normative limits. Therefore, it is necessary to expand discussions regarding the pre-treatment carried out on textile sludge, as well as its impacts on mechanical and environmental performance.

Resumo Olodo têxtil é um resíduo do tratamento do efluente das lavanderias têxteis e sua incorporação em materiais alternativos tem sido proposta como possibilidade para sua destinação. Foi realizada uma busca sistemática na literatura nesta perspectiva, visando observar as concentrações de material residual e seu preparo, as matrizes utilizadas, o desempenho tecnológico e imobilização do resíduo têxtil. As matrizes empregadas foram argamassas, concretos e tijolos cerâmicos, sendo observados, de maneira geral, efeitos deletérios nas características mecânicas dos materiais produzidos. Em concretos e argamassas, a finura impactou no aumento da demanda de água, o que elevou a porosidade das misturas; e a matéria orgânica e metais pesados, na hidratação do cimento. Estudos recentes propuseram, então, o pré-tratamento do material residual como uma alternativa favorável. Incrementos na porosidade também ocorreram nos tijolos cerâmicos, porém, devido ao elevado teor de matéria orgânica. Quanto a imobilização do resíduo, os materiais cimentícios apresentaram desempenho satisfatório; já os tijolos cerâmicos, obtiveram alguns resultados fora dos limites normativos. Portanto, é necessário ampliar as discussões quanto ao pré-tratamento realizado no lodo têxtil, bem como seus impactos no desempenho mecânico e ambiental.

Abstract Given the environmental impacts associated with the production of conventional Portland cement, the study of special cements with reduced environmental impact has been a trend. In this context, cements containing ye'elimite (YCC) stand out due to their low CO 2 emissions. Despite the environmental advantages, the high demand for aluminum economically limits the production of these cements.An alternative to making its production feasible is using residual raw materials as a source of Al 2 O 3 , such as SFCC (spent fluidized catalytic cracking).In view of this, this work aims to evaluate hydration at the initial age of cements. For this, six clinkers were produced with different ye'elimite contents, with and without SFCC. These were characterized by XRD/Rietveld. The pastes were evaluated by TG/DTG and XRD/Rietveld to understand the hydration mechanism on the third day of these cements. It was possible to synthesize the main phases of YCC, in clinkers with and without SFCC. In addition, at the age evaluated, the pastes with and without SFCC presented comparable phase composition, indicating the potential for co-processing this residue.

Resumo Diante dos impactos ambientais associados à produção do cimento Portland convencional, o estudo de cimentos especiais de reduzido impacto ambiental tem sido uma tendência. Neste contexto, os cimentos contendo ye’elimita (YCC) se destacam devido à baixa emissão de CO2. Apesar das vantagens ambientais, a alta demanda por alumínio limita economicamente a produção destes cimentos. Uma alternativa para viabilizar a sua produção é o uso de matérias-primas residuais como fonte de Al2O3, a exemplo do SFCC (catalizador gasto do craqueamento catalítico de leito fluidizado). Diante disso, este trabalho tem como objetivo avaliar a hidratação na idade inicial de cimentos YCC produzidos a partir do coprocessamento do SFCC. Para isso, foram produzidos seis clínqueres com diferentes teores de ye’elimita, com e sem SFCC. Estes foram caracterizados por DRX/Rietveld. As pastas foram avaliadas por TG/DTG e DRX/Rietveld para compreender o mecanismo de hidratação em idade inicial destes cimentos. Foi possível sintetizar as principais fases dos YCC, nos clínqueres com e sem SFCC. Além disso, na idade avaliada, as pastas com e sem SFCC apresentaram composição de fases comparáveis indicando o potencial de coprocessamento do SFCC neste tipo de cimento.

Abstract Incorporating BIM in the education of professionals has become a demand and a topic of high importance for higher education. Several proposals for a curricular implementation of BIM exist. However, in most cases, they are specific to a single university or domain, do not consider academic policies or simplify practice by segmenting knowledge. This work proposes a protocol for the curricular implementation of BIM similar to the industry, considering aspects of process, technology, and policies aligned with the educational institution's mission and with existing competencies. Action research was the used method. Three actions were conducted: (1) proposition, (2) systematization and (3) application. The actions were executed in cycles incrementally, resulting in (1) guidelines, (2) supporting tools and (3) implementation plans. Two Brazilian universities participated in pilot studies of Project Construa Brasil. The pilot studies inspired a network of BIM cells that have synchronously applied curricular BIM implementation guidelines on a large scale. The guidelines proved to be generic and comprehensive, guiding the transformation with an empirical basis for the academics' decision-making. Leadership of a BIM specialist was confirmed as an essential factor of success. It is observed that even with a timid introduction of BIM competence in a limited scope of engineering solutions, the impact on the BIM maturity curriculum is significant.

Resumo Incorporar o BIM na formação de profissionais tornou-se uma demanda e um tema de grande importância para o ensino superior. Existem várias propostas de implementação curricular do BIM. No entanto, na maioria dos casos, são específicos de uma única universidade oudomínio, não contemplam políticas acadêmicas ou simplificam a prática segmentando o conhecimento. Este trabalho propõe um protocolo para a implementação curricular do BIM semelhante aoda indústria, considerando aspectos de processo, tecnologia e políticas alinhados com a missão da instituição de ensino e com as competências existentes. Pesquisa-ação foi o método utilizado. Três ações foram realizadas: (1) proposição, (2) sistematização e (3) aplicação. As ações foram realizadas em ciclos de forma incremental, resultando em (1) diretrizes, (2) ferramentas de apoio e (3) planos de implementação. Duas universidades brasileiras participaram de estudos-piloto do Projeto Construa Brasil. Os estudos-piloto inspiraram uma rede de células BIM que aplicaram as diretrizes curriculares de implementação BIM em larga escala. As diretrizes mostraram-se genéricas e abrangentes, orientando a transformação com base empírica para a tomada de decisão dos acadêmicos. A facilitação de um especialista BIM foi confirmada como fator essencial de sucesso. Observa-se que, mesmo com uma tímida introdução de competências BIM em um escopo limitado de soluções de engenharia, o impacto na maturidade BIM do currículo é significativo.

Lean six sigma (LSS) is 'n belangrike besigheidstrategie vir organisasies, insluitend klein en mediumgrootte ondernemings (KMO's). Oor die jare het KMO's 'n potensieel beduidende impak op verskeie lande se bruto binnelandse produk (BBP) gehad. Die hoofdoel van hierdie navorsing is om die kritieke suksesfaktore (CSF's) vir lean six sigma (LSS) implementering in die Koninkryk van Saoedi-Arabië se KMO's te ondersoek, en om by te dra tot die ontdekking van die faktore wat lei tot besigheidsukses, verhoogde inkomste en verbeterde mededingende voordele.

Abstract Objective: this study estimates a system of demand for food products in Mexico, incorporating territorial and income dimensions. The differentiated impact of shocks on prices on economic well-being and the poverty rate is evaluated, considering variations among households and across five major regions. Methodology: using Deaton’s (1988) unit values model and the 2018 National Income and Expenditure Survey (ENIGH), we calculate price and income elasticities, examining the impact of price variations on income and poverty. Results: our results reveal significant regional differences, emphasizing the need to consider socioeconomic and regional variations and to adopt a territorial approach in such analyses for effective policy formulation. Limitations: there are limitations to this study that may affect a complete understanding of poverty dynamics. We have focused our attention solely on food products, excluding a specific group of products, in this case, fishery products. We also assume that households are only consumers of goods, thus omitting the productive and self-consumption dimension. Originality: lies in the direct link between poverty estimates and territorial disaggregation, integrating consumption patterns and specific elasticities for each region. Conclusions: our study highlights the importance of considering socioeconomic and regional differences when analyzing the demand for food products and its impact on poverty. Despite the limitations, our findings underscore the need for a territorial approach in this type of analysis to formulate tailored and effective poverty reduction policies in different regions of the country.

Resumen Objetivo: este estudio estima un sistema de demanda de bienes alimenticios en México, incorporando dimensiones territoriales y de ingreso. Se evalúa el impacto diferenciado de choques en los precios en el bienestar económico y la tasa de pobreza, considerando variaciones entre hogares y entre cinco grandes regiones. Metodología: utilizando el modelo de valores unitarios de Deaton (1988) y la Encuesta Nacional de Ingresos y Gastos de los Hogares (ENIGH) de 2018, calculamos elasticidades-precios y elasticidades-ingreso y el impacto de las variaciones de precios en el ingreso y la pobreza. Resultados: revelan importantes diferencias regionales y se subraya la necesidad de considerar diferencias socioeconómicas y regionales y de adoptar un enfoque territorial en este tipo de análisis y para formular políticas efectivas. Limitaciones: existen limitaciones a este estudio que pueden afectar la comprensión completa de la dinámica de la pobreza. Hemos enfocado nuestra atención únicamente en los bienes alimenticios, excluyendo un grupo específico de productos, en este caso, los productos pesqueros. También, se considera que los hogares son únicamente consumidores de bienes, omitiendo así la dimensión productiva de autoconsumo. Originalidad: radica en la vinculación directa entre las estimaciones de pobreza y la desagregación territorial, integra patrones de consumo y elasticidades específicas a cada región. Conclusiones: se resalta la importancia de considerar las diferencias socioeconómicas y regionales al analizar la demanda de bienes alimenticios y su impacto en la pobreza. A pesar de las limitaciones, nuestros hallazgos subrayan la necesidad de un enfoque territorial en este tipo de análisis para formular políticas adaptadas y efectivas de reducción de la pobreza en diferentes regiones del país.

Resumen: El objetivo de este estudio es evaluar el efecto de la atmósfera, definida como el diseño consciente del ambiente de la tienda para crear ciertas respuestas en los compradores, en los valores de compra, la actitud hacia la compra y las emociones sobre la intención de recompra en una tienda online, basado en el modelo Estímulo-Organismo-Respuesta (S-O-R, por sus siglas en inglés). Aunque estos elementos han sido estudiados ampliamente en el contexto de tiendas físicas, artículos recientes que analizan la influencia de estos elementos en el ambiente online muestran la relevancia de estudios como este en investigaciones académicas actuales de mercadeo. Los resultados de una encuesta realizada a 306 usuarios de una tienda farmacéutica online, residentes de Venezuela y otros países de América Latina, se analizaron usando ecuaciones estructurales. Los hallazgos permiten concluir que el uso del modelo S-O-R es apropiado en la predicción del comportamiento de compra online, y confirman que el valor de compra hedónico tiene un impacto directo significativo tanto en la actitud hacia las compras como en la compra emocional. Por otra parte, el valor de compra utilitario afecta negativamente la compra emocional y el factor informático favorece la actitud hacia las compras. Por último, la actitud hacia las compras y la compra emocional predicen la intención de recompra. Se discuten las implicaciones para los especialistas en marketing.

Abstract: The objective of this study was to evaluate the effect of the online store atmosphere, shopping values, attitude toward online shopping and emotions on the repurchase intention in an online store, based on the Stimulus-Organism-Response model (S-O-R). Although these elements have been studied in the context of brick-and-mortar stores, recent articles that analyze the influence of these elements in the online environment demonstrate the relevance of this study in current marketing research. The results of an online survey conducted with 306 users of an online pharmaceutical store, which included residents of Venezuela and of other Latin American countries, were analyzed using structural equations, evaluating both the measurement model and the relationship model. The findings allow us to conclude that the use of the S-O-R model is appropriate in predicting online purchase behavior, having achieved an adequate fit, and confirm that the hedonic purchase value has a significant direct impact on both the attitude toward online shopping and the emotional purchase. On the other hand, the utilitarian purchase value negatively affects the emotional purchase and the computer factor favors the attitude toward online purchase. Finally, the attitude toward online shopping and the emotional purchase predicts the repurchase intention. Implications for marketers are discussed.

Resumen: Cuando las empresas comprenden las variables que impulsan la satisfacción de los clientes, pueden establecer mejores puntos de referencia y perfeccionar sus estrategias. En la actualidad, existe un crecimiento exponencial de las compras de ropa de moda a través de plataformas digitales. Esta investigación evalúa si la orientación a la moda rápida y a la moda lenta, la conciencia ambiental y las experiencias del producto, emocional y con el sitio web inciden sobre la satisfacción con la compra en línea. Además, se analiza la importancia y el rendimiento de las experiencias sobre la satisfacción. Las técnicas estadísticas utilizadas son un modelo de ecuaciones estructurales basados en mínimos cuadrados parciales y una matriz de importancia-desempeño. El diseño de investigación fue cuantitativo, explicativo y transversal, desarrollado en la frontera norte de México y aplicado a 539 compradores de ropa en plataformas web o aplicaciones digitales. Los resultados evidencian que solo la orientación a la moda lenta influye sobre la conciencia ambiental, a diferencia de la orientación a la moda rápida que no tiene efecto en ella, la conciencia ambiental tiene un impacto positivo sobre los tres tipos de experiencia y éstos inciden favorablemente sobre la satisfacción con la compra de ropa en línea. La matriz importancia-desempeño evidenció que la experiencia con el sitio web/app es el factor más relevante para la satisfacción en línea. En conclusión, la satisfacción con la compra en línea depende en gran medida de la experiencia con el sitio web.

Abstract: Companies that understand which variables drive customer satisfaction can establish stronger metrics and refine their strategies. Currently, there is an exponential growth in fashion shopping through digital platforms. Our research assesses if fast fashion and slow fashion orientation, environmental awareness, and product, emotional, and website experiences have an effect on satisfaction with online shopping. Moreover, the importance and performance of experiences on satisfaction is analyzed. Statistical techniques used are a structural equation model based on partial least squares and an importance-performance matrix. The research design was quantitative, explanatory, and cross-sectional, conducted in the northern border of Mexico and applied to 539 clothing shoppers on web platforms or digital applications. The results show that only the slow fashion orientation influences environmental awareness, unlike the fast fashion orientation that does not have an effect on it, environmental awareness has a positive impact on the three types of experience, and they favorably impact satisfaction with the purchase of clothing online. The importance-performance matrix revealed that the website/app experience is the most relevant factor for online satisfaction. In conclusion, satisfaction with online shopping is highly dependent on the website experience.

Resumen: La investigación, con enfoque epistemológico cuantitativo y el paradigma positivista, tiene como objetivo definir la relación entre el marco regulatorio del sector financiero ecuatoriano y las condiciones de financiamiento a las pymes. Esta fue de tipo descriptivo-correlacional, permitiendo realizar un análisis descriptivo y factorial de variables vinculadas al conocimiento y aplicación de leyes y códigos regulatorios de 54 oficiales de crédito del sector bancario de El Oro, Ecuador. Se identificaron dos dimensiones: una relacionada con el marco regulatorio monetario y otra con códigos orgánicos. Las encuestas señalan que las leyes más aplicadas son: Ley General de Instituciones del Sector Financiero y Ley de Compañías. La primera regula la creación, funcionamiento y cierre de instituciones financieras privadas para proteger a la población y asegurar la estabilidad financiera; su cumplimiento es supervisado por la Superintendencia de Bancos. La segunda simplifica el proceso de constitución de empresas, permitiendo diversos tipos de compañías y flexibilidad en su estructura. Las regulaciones bancarias ecuatorianas han experimentado reformas para fortalecer la solidez y transparencia del sistema, como la Ley de Mercado de Valores y la Ley de Instituciones del Sistema de Seguros Privados, que contribuyen a la estabilidad, regulación, protección al consumidor financiero y promoción de la competencia, generando condiciones de financiamiento favorables, que incluyen confianza, tasas de interés competitivas y amplias opciones financieras.

Abstract: The research, with a quantitative epistemological approach and the positivist paradigm, aims to define the relationship between the regulatory framework of the Ecuadorian financial sector and the financing conditions for SMEs. This was of a descriptive-correlational type, allowing a descriptive and factorial analysis of variables linked to the knowledge and application of laws and regulatory codes of 54 credit officers from the banking sector of El Oro, Ecuador. Two dimensions were identified: one related to the monetary regulatory framework and another with organic codes. Surveys indicate that the most applied laws are: General Law of Financial Sector Institutions and Companies Law. The first regulates the creation, operation and closure of private financial institutions to protect the population and ensure financial stability; Its compliance is supervised by the Superintendency of Banks. The second simplifies the business incorporation process, allowing various types of companies and flexibility in their structure. Ecuadorian banking regulations have undergone reforms to strengthen the soundness and transparency of the system, such as the Securities Market Law and the Law of Institutions of the Private Insurance System, which contribute to stability, regulation, financial consumer protection and promotion of competition, generating favorable financing conditions, which include confidence, competitive interest rates and broad financial options.

Abstract Sexual satisfaction is expressed as an evaluation to gauge the level of enjoyment in one’s sexual life. Studies of the sexuality of the LGBTIQ population have been limited, as this group grapples with taboos, repression, and social stigma, which impact various aspects of their lives, including health and sexual satisfaction. This study investigates the unidimensional scale of sexual satisfaction in the LGBTIQ population in Ecuador, We analyze how this scale is affected when compared to different sociodemographic variables. We utilized a quantitative, descriptive, correlational, and prospective methodology, applying a questionnaire to 625 residents of Ecuador to gather sociodemographic data and the Sexual Satisfaction Index (SSI). The results on the unidimensional scale of sexual satisfaction are as follows: 33% of respondents report sexual satisfaction, while 60.5% experience sexual dissatisfaction, and 6.6% undergo a severe stress experience. There is less sexual dissatisfaction among individuals living in Quito, males, homosexuals, those with a higher level of education, and Afro-Americans, with a P value < 0,005 that is statistically significant. A negative value of sexual satisfaction is observed in the studied population, emphasizing the need for further investigation into the causes and factors influencing sexual dissatisfaction. This will help us understand their needs and provide support in a safe and respectful environment due to ongoing discrimination.

Resumen La satisfacción sexual se expresa como una evaluación, para manifestar el nivel de agrado a la vida sexual. Los estudios en la sexualidad de la población LGBTIQ han sido poco profundizados, grupos rodeados de tabúes, víctimas de una represión y condenas sociales; afectando las diferentes dimensiones de la salud, como la satisfacción sexual. Este trabajo investiga la escala unidimensional de la satisfacción sexual en la población LGBTIQ Ecuador. Se analiza cómo esta escala es afectada al correlacionarse con las diferentes variables sociodemográficas. Se utiliza una metodología cuantitativa, correlacional descriptiva y prospectiva. Se aplica: cuestionario a 625 personas residentes en Ecuador con recogida de datos sociodemográficos, Índice de Satisfacción Sexual (ISS). Los resultados de la escala unidimensional de satisfacción sexual muestran que el 33 % de la población tiene satisfacción sexual, el 60,5 % experimenta insatisfacción sexual y un 6,6 % reporta una experiencia severa de estrés en esta área. Se observa una menor insatisfacción sexual en los residentes de la ciudad de Quito, en hombres, en personas homosexuales, en aquellos con un nivel educativo más alto y en individuos afrodescendientes, con un valor de p < 0,005, lo que indica una significancia estadística. Estos resultados reflejan un nivel negativo de satisfacción sexual en la población estudiada. Por lo tanto, se hace necesario continuar investigando la satisfacción sexual para comprender las causas y los factores que inciden en la insatisfacción sexual. Es crucial visibilizar las necesidades y los apoyos que requiere esta comunidad en un entorno seguro y respetuoso, especialmente considerando los constantes actos de discriminación que enfrentan.

Abstract Violence against women is a serious public health problem, with a marked social and economic impact. The objective of this article is to synthesize the theories that explain violence against women, contributing, from a theoretical perspective, to the understanding of risk factors. The research is basic and descriptive; the analytical-synthetic method was used to establish the essential elements of the information collected and formalize conclusions in this regard. The search for bibliographic sources was carried out in the Google Scholar database. Theories such as the cycle of violence, traumatic union, paradoxical punishment, battered women, among others, are presented. In addition, the importance of factors such as poverty, victimization, dysfunctional families, ineffective educational and judicial systems is recognized. Risk factors for gender violence were identified according to the different theoretical positions analyzed. The conclusions recognize the conduct of a significant amount of research on violence against women in the context of the pandemic. The proposal of theoretical foundations for each of the risk factors was made, which contributes to future research, especially in the Latin American space. It is considered that theories must be understood within the very dynamics that this phenomenon presents, focused on the variety of criteria, elements, variables, causes, consequences, conditions, etc.
