Architectural heritage faces challenges due to material deterioration and limited technical documentation for structural analysis. This study applies the Scan-to-HBIM-to-FEM workflow, integrating photogrammetry (SfM), terrestrial laser scanning (TLS), HBIM modeling, and finite element simulation to the San Antonio de Padua Church in Riobamba, Ecuador. The results demonstrate a three-dimensional model with high geometric accuracy (deviations < 0.2%), suitable for structural analysis. FEM simulation allowed for the identification of critical stress zones and their relationship to geometric irregularities. It is concluded that the proposed workflow is effective for the documentation and structural evaluation of heritage sites. © (2026), (Rey Juan Carlos University). All rights reserved.

This study addresses the need to align the design and production of children’s footwear with the real expectations of its target users—children aged 8 to 12 and their parents. The primary objective was to develop a user-centered design management model grounded in co-creation and design thinking. A mixed-methods approach was employed, incorporating qualitative tools (expert interviews, podcast engagement, and user habit surveys), complemented by a thorough documentary analysis of ISO 9001:2015 and related guidelines. Findings reveal that ergonomic comfort, durability, appealing design, and affordability are key criteria for consumer satisfaction. Moreover, the research underscores the importance of systematically incorporating the user’s voice during early design and validation phases. Interdisciplinary collaboration and user-centered design methodologies emerged as critical for enhancing development processes, customer loyalty, and product competitiveness. This research presents a structured framework that integrates active user engagement, innovation, and quality assurance, offering a robust pathway to meet and exceed the expectations of the children’s footwear market. © 2026, Common Ground Research Networks.

The rapid urbanization worldwide, particularly in developing countries, has intensified the demand for community services, including spaces that foster social cohesion and physical activity. However, the limited state budget often results in the allocation of land without adequate infrastructure, termed as “stadiums,” which fails to meet the functional needs of both players and spectators, while also contributing to environmental degradation. To address these challenges, this study proposes the design of low-cost, multipurpose structures utilizing ephemeral architecture and sustainable practices, aimed at providing flexible and adaptable solutions for informal sports spaces. This research focuses on neighborhood stadiums in Ambato, Ecuador, employing a comprehensive mixed-methods approach, including quantitative surveys, qualitative interviews, and field observations, to thoroughly assess the specific needs and characteristics of these spaces. Through an in-depth analysis of existing references, a conceptual design framework was developed. The multipurpose objects were then designed using ArchiCad, OPENLCA, and Formit software, enabling comparison with conventional infrastructures. The environmental impact of primary materials was rigorously evaluated through a life cycle assessment (LCA) in OPENLCA, complemented by an energy efficiency analysis conducted with Formit, offering a holistic approach to sustainable design. The results indicate that the proposed multipurpose structures provide a demountable and adaptive solution, significantly reducing carbon emissions and optimizing solar radiation usage, primarily using wood, as opposed to conventional fixed structures that rely on concrete. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2026.

Despite growing interest in natural fibers for sustainable construction, few studies systematically integrate empirical mechanical testing of Andean biomaterials—such as totora (Schoenoplectus californicus)—with parametric design to enhance structural performance. Historically limited to non-structural applications, totora’s potential in load-bearing systems remains underexplored. This study addresses this gap by evaluating and optimizing totora-based modular units through a hybrid methodology that combines traditional weaving techniques, physical testing, and computational simulation. Cylindrical and conical modules, fabricated using cross-weaving and spiral braiding, were subjected to tensile and compressive load tests. Concurrently, ephemeral structures composed of these modules were developed in Rhinoceros using Grasshopper/Karamba3D to explore geometry optimization and load response, iteratively refining morphologies based on stress distribution patterns. Results demonstrate that conical forms and spiral configurations significantly improve stiffness and load dissipation, while all modules exhibited high ductility and full shape recovery after compression. The study confirms that parametric design can effectively compensate for totora’s inherently low strength by adapting form to material behavior. This approach offers a replicable framework for integrating vernacular knowledge with digital tools in sustainable, ephemeral architecture across Andean contexts. © 2026 ISEC Press.

Background/Objectives: Andrographolide (ADG) is a plant-derived compound with promising anticancer properties, but its medical use is limited due to poor water solubility and low bioavailability. This study proposes developing a gold-based nanocomposite drug delivery system, using a simplified synthesis method, to improve ADG’s hydrophilicity and enhance its delivery efficiency. Methods: A one-step method was used to synthesize gold nanocomposites with carbon quantum dots (CBQDs) and doped CBQDs acting as reducing and stabilizing agents. These nanocomposites were then conjugated with ADG and thoroughly characterized using multiple structural and spectroscopic techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), ultraviolet–visible spectroscopy (UV–Vis), transmission electron microscopy (TEM), Raman spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy. Hydrophilicity enhancement was evaluated using NMR-based log P measurements. Biological assessment involved cell viability assays and confocal microscopy studies in PC3 prostate cancer cells, along with the morphological evaluation of human red blood cells. Results: XRD confirmed the formation of crystalline, face-centered cubic gold nanoparticles, while spectroscopic analyses verified successful nanocomposite formation and ADG conjugation. NMR results showed enhanced hydrophilicity of ADG. Biological tests demonstrated that the nanocomposites were compatible with cells. Conclusions: This study presents a straightforward strategy for synthesizing gold-based nanocomposites that enhance the hydrophilicity and delivery potential of andrographolide, supporting their applicability as nanocarrier platforms for anticancer drug delivery. © 2026 by the authors.
