Published: November 2024

Resumo A gordofobia é uma opressão estrutural que configura grande fator de adoecimento para as pessoas gordas. Este trabalho teve por objetivo investigar alguns dos efeitos da gordofobia na saúde dessas pessoas. Trata-se de uma pesquisa qualitativa que utilizou um questionário on-line respondido por 515 pessoas gordas e ex-gordas de todas as regiões do Brasil, e para realizar a análise de dados utilizou-se a análise temática. Identificou-se que a gordofobia afeta a relação das pessoas gordas com a comida, com a atividade física e afeta sua saúde mental. Promove uma relação transtornada com a comida e também afeta a comensalidade da pessoa gorda. Retira o direito da pessoa gorda se exercitar com segurança e afasta as pessoas gordas da prática de atividades físicas. A gordofobia também compromete a saúde psíquica e social da pessoa gorda e a expõe à internalização do viés de peso. Logo, a gordofobia configura um fator de risco para a saúde das pessoas gordas, pois promove sua exclusão e intensifica sua vulnerabilidade. É preciso enfrentar a gordofobia como um problema de saúde pública e preveni-la, para promover a inclusão e a saúde das pessoas gordas.

Authors: Macêdo Talita Farias Correia , Bispo Júnior José Patrício
Published: November 2024

Resumo O objetivo do estudo foi analisar a atuação e a articulação do trabalho dos agentes comunitários de saúde (ACS) e agentes de combate às endemias (ACE) na prevenção e controle das arboviroses. Trata-se de uma pesquisa qualitativa desenvolvida no município de Vitória da Conquista, a partir de 22 entrevistas semiestruturadas, observação participante nos territórios e análise documental. O referencial teórico-metodológico fundamentou-se numa matriz analítica estruturada em quatro dimensões: Clareza das tarefas e atribuições; Governança e coordenação; Relações com a comunidade; Formação e educação permanente. Os resultados evidenciaram que ACS e ACE apresentam atuação fragmentada e desarticulada. Identificou-se clara distinção de atribuições entre os agentes. A atuação do ACE caracteriza-se pelo controle químico dos vetores. Os ACS não se sentem responsáveis pela vigilância ativa das arboviroses. Evidenciou-se frágil coordenação para o trabalho colaborativo. Não há mecanismos regulares para a atuação coordenada ou compartilhamento de informações e de tarefas. As relações dos agentes com a comunidade são marcadas por contextos de desconfiança e diminuta mobilização comunitária. Foram identificadas fragilidades no processo formativo e ausência de uma política de educação permanente. Sugere-se a necessidade de aprimoramento dos mecanismos de governança e do fortalecimento das estratégias de mobilização comunitária.
Evaluation of fly ash-based geopolymer concrete incorporating coarse and fine recycled aggregates
Authors: Singh Paramveer , Kapoor Kanish
Published: December 2024

Geopolymer concrete (GC) is emerging as a promising material as it has a lower carbon dioxide footprint than conventional Portland cement concrete. One of the ways to further enhance the sustainability of GC is by incorporating recycled aggregate (RA). The focus of this study was on evaluating the performance of GC made with coarse recycled aggregate (CRA) and fine recycled aggregate (FRA). The compressive strength and long-term durability properties of GC mixes made with different amounts of CRA and FRA were evaluated. All the GC mixes were also subjected to ultrasonic pulse velocity and electrical resistivity tests. The results showed that FRA content above 25% and 50% CRA had an adverse impact on the long-term durability properties of the GC. The GC mix with 50% CRA and 25% FRA showed compressive strength and electrical resistivity values similar to those of GC made with natural aggregate. The findings from this study are expected to provide valuable insights into the optimal use of RA in GC and contribute to the broader goal of developing sustainable construction materials.

Authors: Xue Bai
Published: December 2024

The brick–timber structure buildings built before 1950 in Shanghai were designed and supervised by European architects and engineers, and the actual construction work was implemented by Shanghai’s artisans. The structural construction combines Chinese and European techniques. They are a typical example of the integration of Chinese and European cultural and architectural styles. The durability, safety, and usability issues of brick–timber structure old buildings are prominent. Therefore, analysis of the structural characteristics of brick–timber structure buildings is necessary to protect these excellent cultural heritage sites. Statistics of the typical characteristics of modern brick–timber structure buildings in Shanghai were made based on 120 brick–timber structure building inspection reports and the design data. This paper has analysed the following four aspects: the building type and year of construction; materials; construction methods; damage situations. The contents above aim to provide a basis and theoretical foundation for the inspection, evaluation, reinforcement, and renovation of modern brick–timber structure buildings in Shanghai.

Published: December 2024

This paper presents experimental investigations on the joints of concrete frame beams and columns with 20% coal ash slag replacing cement. The failure mechanism of concrete frame joints with coal ash slag as a cement replacement is examined, focusing on the impacts of two scenarios – concrete with 20% coal ash slag and ordinary concrete – on the failure mode and seismic performance of beam–column joints, as well as the influence of varying concrete strength grade when the coal ash slag content is 20%. The main research variables are the presence of coal ash slag in the concrete and the concrete strength grade. Findings reveal typical failure modes at the beam-end flexural plastic hinge, progressing through stages of initial cracking, yielding, limit and failure. Joints without coal ash slag exhibit 10.3–16.2% higher ductility, while those with 20% coal ash slag show a 14% improvement in bearing capacity. The C50 joint with 20% coal ash slag outperformed the C40 joint in bearing and energy dissipation, with robust hysteretic curves meeting seismic requirements. Thus, replacing 20% of cement with coal ash slag enhances the durability and seismic performance of concrete components.

A könyv egy olyan eszköz, ami nélkül a tanítás és a tanulás elképzelhetetlen lenne. Az infokommunikációs eszközöknek köszönhetően ma már nem csak nyomtatott, kézzel megfogható, papíralapú könyvre gondolhatunk, hanem képernyősre is. Az utóbbit a kor adta újításoknak köszönhetjük, mivel már elektronikus formában hozzáférhetünk a néhány megabyte nagyságú, értékes szöveghez, akár ingyenesen is. Ezeket akár okostelefonokon, laptopokon, e-könyveken stb. nyithatjuk meg és olvashatjuk el. Azonban nem ugyanaz egy nyomtatott és egy elektronikus könyv olvasás. A kérdés az, hogy a könyv helyét átveheti a képernyő? A kutatás célja megvizsgálni a könyv és a képernyő közötti eltéréseket, az oktatásban betöltött szerepeiket, és választ kapni arra a kérdésre, hogy vajon melyik tárgyat használjuk leginkább a sikeres tanítás elérése érdekében. Vajon a tanuláshoz mennyire mindegy, hogy miből tanulunk és mit fogunk a kezünkben?

Identidades y enseñanza de las ciencias sociales. Estudio de casos desde tres lugares del mundo.
Authors: Tosello Julia
Published: December 2024

The construction of identities is of relevance for the teaching of democracy and social sciences (Santisteban y Pagés, 2007). With their imprint on action and anchoring in the future, identities are dynamic, narrative, historical, social, plural and permanent constructions, through which the world is interpreted and subjectivities are organized (Hall, 1996). From an interpretative and critical perspective, this paper aims to explore and analyze what the secondary curriculum of Social Sciences in Argentina, Catalonia and South Africa say about identities, and then, based on testimonies about the practice, establish some possible guidelines for potential proposals and curricular innovations on the subject. Through a mainly qualitative methodology (Eisner, 1990), the curriculums are approached through a document analysis (Rapley, 2014); the testimonies -corresponding to questionnaires and interviews made to some members of the professoriate of the three sites - are analyzed by emphasizing the perspectives on the practice by investigating and interpreting their meaning (Flick, 2015). Although in all three curriculums identities are assumed as social, historical and temporal constructions (Grossberg, 1996), in each case it occurs in a different way and with its own characteristics. A majority of teachers conceive identities as traits or characteristics of people and a minority thinks of them as constructions. Among the possible contributions for potential curricular innovations are emphasized in the identities as social constructions and in their relevance in the teaching of the social sciences.

Published: December 2024

The area of Social Sciences Teaching has been consolidated in our country as an autonomous area of knowledge, with its own entity, which continues to grow in the volume and quality of its research. The proof of this is the trajectory of more than three decades and the significant increase in the scientific works published in recent years. These research have been published in scientific journals, compilation books or conference proceedings, and have also been defended as theses that have investigated various problems of study. As a consequence of the increase in contributions, we consider it pertinent to elaborate a status of the issue which will resituate the research in the area and open up new perspectives for study. Starting from it, we analyze with a double methodological perspective, quantitative and qualitative, the contributions presented to the last Symposium of the University Association of Teaching of Social Sciences Teaching (AUPDCS), entitled: “Looking for ways to teach: research to innovate in Didactics of the Social Sciences”, which took place in March 2018 at the University of Valladolid. Our objective has been to know if these contributions give continuity to the usual lines of research that have been worked in the area, or if, on the contrary, they break with them, investigating new topics. The analysis carried out shows, among other aspects, the increase in novel research and studies that focus on educational stages unknown until now.

In this article we analyze the ideological perspective adopted by a group of normalist new students in relation to the current economic, political and social problems in Mexico, from this we verify the ability they have to relate the past, the present and the future. It constitutes an exercise to identify and categorize typologies of historical consciousness in them. The document represents the result of a qualitative diagnostic investigation developed at the Urban Normal School of the Isthmus located in Ixtepec city, Oaxaca, during the 2014-2015 school year. The research questions that were intended to be solved were the following: Is the cultural and ideological perspective that students show in their opinions in relation to current social problems? What type or level of ideological awareness do they adopt in relation to past events and social situations of the present? What relationship is established between the ideological characteristics of the subjects and their professional training (initial) as teachers? How can a historical - critical consciousness be developed in future teachers? In order to obtain field information in relation to this problem, a diagnostic-questionnaire was applied to the subjects under investigation. Based on the analysis of the information obtained, three types of historical awareness could be defined that characterize students' thinking, according to the approach of the students. Paulo Freire these are: magical awareness, naive awareness and critical consciousness, which is explained in greater detail in the body of this paper.
La olvidada geografía rural en el currículo y manuales de la educación secundaria
Authors: Armas Quintá Francisco Xosé , Rodríguez Lestegás Francisco , Macía Arce Xosé Carlos
Published: December 2024

The presence of rural geography in the curriculum and textbooks of Compulsory Secondary Education and Baccalaureate is scarce and references to rural areas imply an association with the primary sector in general and with agriculture in particular. The contents gathered in the curriculum for the different courses of secondary education include the study of the Spanish population, its distribution and dynamics, the migratory movements, and the process of urbanization. No reference is found to the aging and economic decline of many Spanish rural areas in the last decades of the twentieth century due intense migration towards cities. Nevertheless, contents do emphasize a complex issue: the elements of differentiation between urban and rural areas in Europe. Textbooks follow the guidelines set in the curriculum, thus ignoring anything related to the rural dynamics and transformations of the last decades. The intense process of urbanization that has taken place at the regional, national and European levels cannot be explained without taking into account the changes that have taken place in these areas. The study of rural areas should not to go unnoticed in secondary school, especially its new dynamics resulting from the dissemination of information and communication technologies.

Authors: Izquierdo Grau Albert
Published: December 2024

This dissertation analyzes the critical capacity of students when placed in front of a relevant social problem such as the hate speech, given that a great part of the information transmitted by the media or social networks is marked by the presence of hate speech. The research has been carried out among students in their third and fourth years of Secondary Education in three educational centers in the area of Barcelona. The results of the study have been obtained from different research activities: class activities with open and closed questions, for instance, the analysis of stories that appeared on social networks; discussion groups; interviews with Social Sciences teachers; and the analysis of the Catalan and Spanish Secondary Education curriculum. This article shows the results obtained from two questions from the dossier, answered by 159 students. The aim of this study is to verify the ability of students to analyze hate speech and build counter-narratives (of hate based) on the stories that appear on social networks and the media. The results obtained thus far, confirm that students do not seem to be capable of critical literacy in order to build counter-narratives of hate.

The utilization of precast wall panels has gained prominence due to its potential for enhancing construction speed, quality, and sustainability. One critical aspect of precast construction is the connection between wall panels, where it is one of the proven to be the weakest link in the system. Rigidity of the connection between panels was also a point of concern. This research aims to investigate the mechanical performance of the dapped wet connection model in the vertical wall-to-wall connection in application for precast wall panels, particularly focusing on shear load considerations. The investigation includes experimental testing that includes three pair of specimens subjected to shear loading to evaluate their shear strength capacity, strain, and connection flexibility behaviour as well as the resulting crack propagation throughout the test. The test was verified through Acoustic Emission (AE) technique using Energy (eu) parameter. The proposed sample tested shows a significant improvement compared to the control sample with respect to maximum shear strength, however it displays a brittle behaviour by developing multiple cracks along the connection interface and having a significant shear failure at the end of the test. The findings of this study will contribute to a better understanding of the behavior of dapped wet connection and provide preliminary guidance for their design in precast concrete wall panels.

The use of recycled concrete aggregate (RCA) in the production of concrete structures in Malaysia is minimal and does not match the amount of recycled concrete waste produced during a similar period. Moreover, there is a growing need to shorten the construction period, which necessitates the use of lighter concrete materials to produce lighter material with a minimal strength that able to act as part of the structures. Hence, this study aims to analyse the physical and mechanical properties of control strength lightweight mortar (CSLM) made from RCA and expanded perlite (EPA). The nominal size of crushed RCA and EPA was 4.75 mm, like the natural sand (NA) used. Several ratios of RCA, NFA, and EPA (fine aggregate) were employed to determine the optimal ratio of fine aggregate to cement. The CSLM underwent testing for its uniaxial compressive strength at 3, 7, and 28 days, while flexural strength was tested only at 28 days. It is found that the ideal proportion of RCA and EPA in CLSM is 40% and 20% of the total fine aggregate content, respectively. Meanwhile, the optimal mix ratio for CSLM consists of 40% RCA, 40% NFA, and 20% EPA. Hence, it can be concluded that the presence of residual mortar in RCA increased the water absorption rate, resulting in lower compressive and flexural strength when higher proportions of RCA and EPA were used. Studying CLSM using RCA and EPA offers the benefit of creating more sustainable construction materials by reducing waste and conserving natural resources.

Water footprint (WF) can be used as a comprehensive indicator of the use of freshwater resources and as a measurable metric to determine the amount of water used per unit of crop. Rice cultivation uses large amounts of water to increase crop yields. Since water is the most important component for rice cultivation, it is important to understand how much water is used during agriculture and the quantity of water in the rice crop per ton of product. The aim of this study is to evaluate the water footprint of rice crops in the Muda area regulated by the Muda Agricultural Development Board, for five consecutive years from 2018 to 2022. CROPWAT 8.0 computer programming, meteorological data such as (rainfall, temperature, speed wind, relative humidity, and solar radiation) and rice crop yield data are used to estimate water evapotranspiration (ET) for the blue and green water components, and continue the water footprint calculation. Methodological framework according to crop water requirements options based on the water footprint assessment manual. The water footprint calculation focuses on the blue, green, and grey water footprint components. The findings of the study show that the three components of the water footprint differ significantly from each other. In the Muda area, the average value of the green water footprint (WFgreen ) is 1102.3 m3/ton (56.6 %) higher than the blue water footprint (WFblue ) which is 506.4 m3/ton (26 %), and the value of the grey water footprint (WFgrey ) is 337.4 m3/ton (17.3 %). 57 % green water footprint indicates that there is enough rain to support rice growth. Water footprint assessment provides more comprehensive understanding of the environmental sustainability of rice crops. Data from the assessment can be used to formulate policies that promote sustainable rice cultivation and the best cultivation methods.

The increasing population and modern lifestyle demand have caused the increase in waste sludge production gradually at the same time causing environmental pollution. Thus, the idea of reusing this waste sludge emerges as an alternative way of reusing it to create a product instead of disposing it. The Naphthalene sludge, a by-product obtained from the production of superplasticizer, also known as concrete admixture, is used in this study as an additive in concrete. Concrete was produced with 0%, 1%, 2% and 3% additive of the naphthalene sludge and the workability and strength of mortar and concrete were studied to investigate the effect of the waste sludge on concrete. Samples for compressive strength test were prepared with fixed Water-cement (W/C) ratio of 0.50 and cured for 7 and 28 days. The results showed an increase of concrete and mortar strength when the waste sludge addition is increased. 3% of Naphthalene sludge additive shows the highest concrete strength based on the 28 days strength and obtained the best workability among the control sample and the other 1% and 2% of additive. By adopting sustainable practices in waste management and innovation can mitigate adverse impacts while supporting global sustainability development goals (SDG) 2030.

The current study aimed to enhance dye decolorization by integrating adsorption and enzymatic degradation processes using laccase immobilized in silica microparticles. In-situ immobilization of laccase was achieved via solgel technique through two-step (acid–base catalyst) methods, employing hydrolysis and condensation of tetraethyl orthosilicate (TEOS) as the precursor. Various parameters, including pH, temperature, dosage loading, and reaction time, were meticulously examined to optimize the process. The findings revealed that combination of immobilized laccase significantly improved the decolorization of malachite green dye by over 20% compared to single adsorption using silica alone. The highest decolorization efficiency of 94.21% was attained through the synergistic effect of adsorption and enzymatic degradation facilitated by immobilized laccase in silica. This immobilization not only enhanced the enzyme’s stability but also made the decolorization process more efficient. The study underscores the potential of silica-immobilized laccase as a powerful decolorizing agent, which could also be applied to the degradation of other contaminants in wastewater. This innovative approach highlights the advantages of combining adsorption with enzymatic degradation, offering a promising solution for treating dye-laden industrial effluents. The enhanced stability and efficiency of the immobilized enzyme demonstrates a significant advancement in the field of bioremediation, paving the way for more effective and eco-friendly methods to address water pollution.

The design of traditional Malay houses is influenced by Islamic values in aspects of privacy, user comfort, and environmental sustainability. The problem in the context of living space arrangements today is less adaptation to the local climate and culture of family and community that is emphasized in Islam. The objective of this study is to understand how Islamic principles of user comfort, privacy and sustainability are applied in the design of traditional Malay houses and to evaluate their effectiveness. This study was conducted on several traditional houses at Universiti Putra Malaysia - Rumah Penghulu Ismail bin Khatib Bakar, Rumah Haji Wan Muda Haji Wan Hassan, Rumah Perak Uda Noh B. Kandar Jaafar, and Rumah Datuk Raja Diwangsa Muhammad Yunus bin Jabar, as well as several other traditional houses. The houses were chosen to represent each different state as they have different regional cultural values and microclimates that make the architectural design different from each other. Through data analysis obtained from field observations, questionnaires, literature reviews, and expert interviews, the findings show that traditional Malay houses are designed to ensure privacy through separate entrances for men and women and the arrangement of sleeping areas.

Malaysia’s water supply has shifted from abundant to scarce, prompting a thorough examination of potential solutions, particularly using Tasik Biru Seri Kundang’s untapped resources. Assessing the reservoir’s capacity to provide clean water consistently amidst increasing demand is crucial. The objective was to analyze Tasik Biru Seri Kundang’s water characteristics to determine its suitability as a drinking water source, which was evaluated through the Water Quality Index (WQI) and heavy metal concentration measurements. The water quality analysis involved field and laboratory testing, assessing parameters such as pH, dissolved oxygen, turbidity, chemical oxygen demand (COD), biochemical oxygen demand (BOD), suspended solids (SS), and ammonia-nitrogen (AN). The findings of the study showed that the pH was 7.26 and 7.67, the dissolved oxygen (DO) was 9.77 and 7.15 mg/L, the chemical oxygen demand (COD) and biochemical oxygen demand (BOD) was 0 mg/L each, the suspended solids (SS) were 10 and 7 mg/L. The ammonia-nitrogen (AN) was 0.08 and 0.1 mg/L, separately. According to the results, all input points were categorized as Class I, indicating that no treatment was required for the water supply. Concentrations of heavy metals, including chromium (Cr), iron (Fe), copper (Cu), zinc (Zn), and manganese (Mn), were measured at levels such as 0.017 and 0.086 mg/L for chromium (Cr), 0.25 and 0.53 mg/L for iron (Fe), 0.21 and 0.26 mg/L for zinc (Zn), 0.09 and 0.08 mg/L for copper (Cu), and 0.021 and 0.044 mg/L for manganese (Mn). While most parameters met WHO standards, chromium levels at the outlet exceeded the permissible limit of 0.05 mg/L, indicating a high concentration of heavy metals. Tasik Biru Seri Kundang exhibits favourable water quality characteristics, primarily meeting drinking water standards. However, elevated chromium levels at the outlet point necessitate corrective measures to ensure compliance with regulatory guidelines and safeguard public health.

Bamboo has been identified as a future material for the primary, secondary, and tertiary sectors of the economy with reference to the Bamboo Industrial Development Action Plan in Malaysia 2021-2030 as bamboo is a natural material with high mechanical qualities and a quick reproduction rate. To support this vision, the construction industry needs structural design values. Currently the structural design values for structural bamboo for Malaysian species are not yet available as most of the R&D is focused on the upstream study and non-structural products. Therefore, this study investigates the physical and mechanical properties of a structural bamboo species namely Buluh semantan (Gigantochloa scortechinii) that is the prominent species being used in structural applications. The preparation of specimens and the physical and mechanical testing; bending, shear and compression in direction parallel to the fiber were conducted in accordance with ISO 22157. The properties obtained were used to derive the characteristic capacity of each property. The determination of allowable stresses is based on the characteristic capacity at 5th percentile in accordance with BS EN14358. These derived outputs provide new design data based on capacity grading for Malaysian bamboo and provide alternative environmental-friendly and sustainable construction materials. The results will be soon incorporated in the ISO Standard. This is aligned with the vision to foster green and sustainability building.

This study delves into the concepts of forgiveness, reconciliation, and nonviolence through the experiences of victims, social leaders, and academics involved in Colombia's peacebuilding initiatives. Using focus groups, audio/video recordings, and thematic analysis, the research developed comprehensive categories situated within Bronfenbrenner's bioecological framework. The results indicate that the journey towards forgiveness, reconciliation, nonviolence, and peace encompasses a gradient extending from individual subjective experiences to broader sociocultural contexts. These findings underscore the critical importance of addressing structural inequalities and upholding rights, with implications that resonate profoundly within Colombia's ongoing peacebuilding efforts. Victims provided narratives in a deeply personal and communitarian manner, while leaders and academics emphasized the pivotal role of the State in ensuring rights and addressing inequalities to facilitate forgiveness and reconciliation processes. Overall, the study underscores the complex interplay between personal, societal, and governmental factors in Colombia's peacebuilding efforts, offering valuable insights for future research and policy development.

BACKGROUND: Digital screening mammography is a key modality for early detection of breast cancer, reducing mortality by 20–40%. Many artificial intelligence (AI)-based services have been developed to automate the analysis of imaging data.
AIM: The aim of the study was to compare mammography assessments using three types of AI services in multiple versions with radiologists’ conclusions.
MATERIALS AND METHODS: Binary mammography scoring scales were compared with several types and versions of AI services regarding diagnostic accuracy, Matthews correlation coefficient, and maximum Youden’s index.
RESULTS: A comparative analysis showed that the use of a binary scale for evaluating digital mammography affects the number of detected abnormalities and accuracy of AI results. In addition, diagnostic accuracy was found to be threshold dependent. AI Service 1 in version 3 had the best performance, as confirmed by most diagnostic accuracy parameters.
CONCLUSIONS: Our results can be used to select AI services for interpreting mammography screening data. Using Youden’s index maximization to set up an AI service provides a balance of sensitivity and specificity that is not always clinically relevant.
