Numerical Analysis of the Effects of Ascending and Descending Corrosion on Steel Columns of Industrial Portal Frames
type: item
description: Objective - To numerically evaluate the impact of atmospheric corrosion on the mechanical behavior of steel columns in portal frames, considering different heights and directions of deterioration propagation. The study aims to understand how thickness loss influences the stiffness and stability of the structure, supporting design and preventive maintenance decisions. Methodology - The research was carried out through numerical modeling using the Abaqus® software, based on the theoretical model proposed by Vogel (1985). Simulations were performed with B21 beam elements, using a 200 mm mesh size. Corrosion scenarios with progressive thickness reductions were considered over exposure periods of 7, 15, 25, and 50 years, according to the guidelines of ABNT NBR ISO 9223 (2024). Originality/Relevance - The work proposes an approach that correlates the height and direction of corrosion with the loss of structural performance, highlighting critical regions and typical deterioration patterns in steel columns. Results - The results show that ascending corrosion exhibits gradual effects, becoming significant only when it reaches approximately 1.0 m in height, whereas descending corrosion causes noticeable deterioration with extensions as small as 0.4 m. A reduction in stiffness and an earlier onset of structural instability were observed, even with small displacement variations. Theoretical/Methodological Contributions - The study enhances the understanding of localized corrosion effects in structural steel members, presenting a replicable finite element–based simulation method. Social and Environmental Contributions - The research reinforces the importance of durability and sustainability in steel structures, promoting the rational use of resources through preventive maintenance strategies and extension of service life. The practical application of the results may reduce rehabilitation costs, minimize material waste, and contribute to more resilient and environmentally respons…

An analysis of the determinants of solid waste disposal in Brazil
type: item
description: Objective – To analyze the evolution of urban solid waste (MSW) management in Brazil between 2014 and 2022 and to identify the socioeconomic factors that determine access to household waste collection. Methodology – This quantitative study combines descriptive analysis of data from the National Sanitation Information System (SNIS) with an econometric model (logit) based on the 2015 Brazilian National Household Sample Survey (PNAD). Originality/Relevance – The research integrates sectoral analysis with empirical identification of the factors influencing access to waste collection services, highlighting critical inequalities within the context of non-compliance with the Brazilian National Solid Waste Policy (PNRS). Results – The sector shows stagnation in selective waste collection (available in only 32.2% of municipalities in 2022) and a 21.2% increase in the number of open dumps. The logit model indicates that residing in an urban area increases the odds of having waste collected by 125 times. Education, income, and being White also positively and significantly impact the probability of access to the service. Theoretical/Methodological Contributions – The study provides an integrated sectoral and econometric analysis, confirming the influence of social determinants on access to essential environmental services. Social and Environmental Contributions – It underscores the need for targeted public policies to reduce inequalities and promote environmental justice, aligning MSW management with the principles of the PNRS.

Sustainability and Health Promoting Universities
type: item
description: Objective: This study aimed to investigate, within the scientific literature, how sustainability principles and practices are being incorporated into the experiences of Health Promoting Universities (HPU). Methodology: An integrative literature review with a qualitative approach, conducted through searches in the CAPES Journals Portal, PubMed, and Google Scholar databases, using the descriptors "health promoting university” AND “sustainability” OR “sustainable development” OR “Agenda 2030,” covering the period from 2015 to 2025. The critical analysis of the 27 selected articles was guided by two main frameworks: the Okanagan Charter (2015), which provides normative reference, guidelines, and principles for the HPU movement; and Van den Hove’s (2007) science–policy–society interface model, which helps to understand the institutional challenges of sustainability in complex contexts. Originality/Relevance: The study addresses a theoretical and methodological gap that remains scarcely explored: the concrete articulation between health, sustainability, and higher education. It reinforces the role of universities as strategic spaces for promoting planetary health, social justice, and ecological transition, contributing to the advancement of the 2030 Agenda goals. The analysis highlights the low degree of institutionalization of the Okanagan Charter guidelines and the fragmentation of sustainable actions in universities, demonstrating the critical originality of the research. Results: A predominance of occasional and theoretical experiences; few empirical studies detail integrated practices of sustainability and health promotion. Significant participation of students and faculty; low involvement of technical staff, administrators, and surrounding communities. Progress in curricular mainstreaming and the emergence of institutional sustainability policies in some institutions. Lack of systematized analysis and evaluation indicators—quantitative or qualitative—and of monitori…

Socio-environmental REDD+ safeguards in Brazil
type: item
description: Objective – Discuss REDD+ safeguards in the Amazon Fund (AF), from 2008 to 2025. Methodology – Narrative literature review and documentary analysis. Four aspects were considered for safeguards analysis: objectives, beneficiaries, operationalization, and results. Originality/Relevance – The topic is little explored in the scientific literature. This article explores socio-environmental aspects of a globally relevant climate fund for climate change mitigation, allowing for important conclusions to be drawn for public policy that considers the challenges raised in the study and climate justice. Results – The positive aspects of the evolution of safeguards in the FA include: pioneering in the adoption of safeguards, the adoption of knowledge generated by civil society, the alignment with REDD+ and methodological advances such as conceptual frameworks for evaluation and guidelines. On the other hand, the following challenges were observed: limitations in transparency and disclosure, lack of clarity regarding sources and current mechanisms for safeguards, and vulnerability to the political context. Considering objectives, beneficiaries, operationalization, and results related to safeguards, the positive aspects include the expansion of priorities and a heterogeneous approach to projects beyond carbon results, the generation of co-benefits, and a broad scope of beneficiaries. Critical observations include the FA being viewed more as a "mechanism for economic innovation" than a "mechanism for social transformation," its effectiveness and ability to demonstrate social impacts are limited, and that there is a lack of incentives for local and multi-level action. Theoretical/Methodological Contributions – The analysis allowed us to systematize the main documents of the Amazon Fund on safeguards and raise the main debates in the scientific literature. Social and Environmental Contributions – Safeguards inherently address social and environmental issues, and we observed that in t…

The role of urban forests in regulating air quality in the face of the effects of climate change
type: item
description: This study aims to synthesize evidence on the contributions of the main component of urban infrastructure to air quality regulation in the face of climate change effects. It is an exploratory study with a qualitative approach, adopting a literature review, in which searches were carried out on the Web of Science, ScienceDirect, and Portal Capes databases. Urban forests are essential for climate regulation, carbon sequestration, and environmental quality improvement, reducing air pollution and contributing to population well-being. The review shows that their benefits are widely recognized, but challenges persist regarding species selection, ventilation conditions, and urban morphology, factors that directly influence pollutant dispersion. It is also highlighted that the concentration of studies in major centers of the Global North indicates the need to expand research in Latin American contexts. This study reveals that urban forests are recognized as a decisive component of green infrastructure or within the sociological systems of cities. Thus, it reinforces the relevance of urban forests for achieving SDGs 11, 13, and 15 for sustainable development.

Mapping of community urban gardens in the municipality of São Paulo, SP
type: item
description: Objective – Mapping community urban gardens in the city of São Paulo, focusing on areas of social vulnerability and Special Zones of Social Interest (ZEIS), and analyze them from the perspective of the integrated approach of the water-energy-food nexus and its relationship with food and nutritional (in)security. Methodology – This is a case study in the city of São Paulo. The methodology consisted of spatial mapping of community gardens and ZEIS using QGIS software (version 3.40.4), based on secondary data from the GeoSampa and Sampa+Rural platforms. The maps were analyzed interpretatively and critically, in conjunction with a literature review on food security and the Nexo approach. Originality/Relevance – This study addresses the theoretical gap in the application of the Water-Energy-Food Nexus Approach to urban agriculture in peripheral areas. Its originality lies in investigating whether community gardens, located in areas of high social vulnerability, can be analyzed as an integrated strategy for optimizing resources and addressing food insecurity, a topic of academic and social relevance for sustainable urban planning. Results – The mapping identified 152 urban gardens in public spaces, of which 114 were classified as community gardens. These gardens are predominantly distributed in peripheral regions (South, East, and North Urban Zones), coinciding with favela and ZEIS areas, i.e., areas with greater socio-environmental vulnerability and food insecurity. The analysis concludes that, despite their good geographic distribution, it is assumed that the productive volume of these gardens is insufficient to significantly impact access to fresh food in these communities. Theoretical/Methodological Contributions – The study contributes theoretically by highlighting the relevance of urban agriculture as a potentially efficient system integrated into urban dynamics. Methodologically, it demonstrates the usefulness of geoprocessing tools (QGIS) and spatial data overlay …

Public spaces and aging
type: item
description: Objective – This study aims to understand how elements of the urban structure support behaviors associated with the subjective well-being of the elderly population. Methodology – Based on behavioral cartographies combining the Static Snapshots and Movement Traces techniques, the behaviors of older adults were recorded along the five blocks of the Calçadão (Pedestrian Street) in Londrina-PR. Non-participant observations were carried out in different shifts (morning, afternoon, and evening) and on three weekdays (Tuesday, Thursday, and Saturday). Originality/Relevance – Given the demographic trend of population aging, the research reinforces the need to rethink urban space as support for the daily lives of a population more vulnerable to health and mobility issues. Understanding how urban configuration relates to the well-being of older adults provides input for interventions aimed at autonomy, safety, and social interaction. Results – The cartographies revealed a consistent sociability pattern: clusters of permanence in attractive points (such as fountains and planters) and in resting areas composed of benches or shaded steps. Headcounts indicated that the presence of older adults was more significant in the afternoon during weekdays, while on Saturdays it was predominantly concentrated in the morning. Theoretical/Methodological Contributions – The research expands the debate on how the built environment influences sociability, permanence, and, consequently, the well-being of older adults. The use of cartographies with a qualitative approach reinforces the importance of capturing social practices in the field and proves effective in identifying patterns of circulation, permanence, and sociability. Social and Environmental Contributions – The study encourages more inclusive and participatory urban policies.

Diagnostic Engineering Applied to Property Appraisal
type: item
description: Objective – To analyze the impact of building pathologies on the depreciation of urban properties and to propose the adaptation of the Ross-Heidecke method to the Brazilian context, aiming to reduce the subjectivity of traditional calculations and increase the reliability of appraisal reports. Methodology – A conceptual and comparative approach was adopted, including a review of depreciation methods used in Brazil and their practical application to a 22-year-old multifamily residential building. The inspection covered common areas and housing units, following the criteria of NBR 15575 and technical protocols for building inspection. Originality/Relevance – The study is original in integrating building diagnostics with property appraisal by incorporating the diagnosis of pathological manifestations as a criterion for defining the depreciation coefficient. This proposal addresses the gap in methods that consider only age and service life, providing greater accuracy in the calculation. Results – A significant variation among the methods analyzed was observed, with depreciation coefficients ranging from 9.88% to 35.02%. The adapted Ross-Heidecke model showed greater potential to represent the real conservation condition of the property, reducing the dispersion of results. Theoretical/Methodological Contributions – The study enhances the technical rigor of depreciation calculations, uses NBR 15575 as a performance benchmark, and suggests a checklist based on pathological anomalies applicable to building inspections. Social and Environmental Contributions – The research contributes to more accurate diagnoses, promotes the valorization of well-maintained buildings, stimulates a culture of preventive maintenance, and provides greater transparency in real estate transactions. Furthermore, it strengthens legal security and supports urban sustainability by encouraging conservation practices.

Walkability and the 15-Minute City
type: item
description: Contextualization: In the face of an increasingly urbanized world, efforts have been directed towards achieving sustainable forms of urban development. In this process, ensuring adequate walkability is essential. Walkability can be conceptualized as the spatial quality of a place that favors the presence of pedestrians in that public space. To measure it, a walkability index is generally used. Relevance: Since the origin of the first indexes in the 1990s, there has been no consensus on which would be the most appropriate tool to evaluate each context, which encourages the continuous emergence of new methodologies. Objective: This article aims to validate the content of the walkability index created by Silva and Silva (2025), formulated from the perspective of the 15-minute city. Methodology: The content validation methodology proposed by Hernández-Nieto (2002) was used, with the voluntary participation of experts in the field, who evaluated the practical relevance and clarity of the tool's language. Results: The walkability index, as well as all its constituent indicators, achieved a Content Validation Coefficient (CVC) above the minimum recommended in the literature (0.70). However, based on the experts' comments, it was possible to identify overlaps between the indicators, which resulted in the removal of four of the initial 31 indicators. Contributions: The results obtained can contribute to the advancement of the literature by providing greater reliability to the index and supporting more accurate diagnoses of walkability.
