In recent years, the field of reality-based 3D model generation has undergone a profound transformation, impacting disciplines such as preservation, archaeology, anthropology, and virtual museums by introducing concepts like virtual heritage and extended reality (XR). The integration of digital models and 3D survey data has become pivotal, enabling immersive experiences and providing unprecedented access to previously inaccessible archaeological sites.In 2022, the Soprintendenza Archeologia, Belle Arti e Paesaggio - Città Metropolitana di Bari embarked on a groundbreaking project to explore Lamalunga cave. This cave, housing a 172,000-130,000-year-old Neanderthal skeleton and 500 faunal remnants, became the focus of an interdisciplinary effort aimed at comprehensively documenting its morphological and typological details alongside the Neanderthal remains. Over a meticulous two-year period, the project meticulously recorded 28 previously undiscovered faunal remains using precise scanning, topographic surveying, and close-range photogrammetry. Central to this endeavor is the Science of Representation, employing advanced 3D modelling techniques such as NURBS algorithms and mesh retopology. These methods facilitated the creation of highly detailed and accurate digital replicas, capturing not only the cave’s intricate physical features but also preserving the contextual integrity necessary for detailed analysis and interpretation of the archaeological findings. This study provides an overview of the digitisation process, examining both the capabilities and limitations of digital models for XR applications. By leveraging cutting-edge technology, this approach enhances preservation, accessibility, inclusivity, and global engagement with one of the world’s most significant Neanderthal sites.DOI: https://doi.org/ 10.20365/disegnarecon.32.2024.6

This research delves into the profound significance of the Science of Representation, demonstrating its pivotal role in crafting semantic and interoperable analysis. The adept application of these ‘mediums’ could represent a primary shift for future generations in how information is conceptualized, interpreted, represented, and communicated, ultimately fostering a deeper level of understanding and collaboration among professionals in the field. In this context, the convergence of digital representation, knowledge-driven semantic refinement, and techniques for intricate model conversion could assume a foundational role. Given these paramount considerations, the study emphasizes the urgency of establishing interoperable procedures and cultivating a comprehensive understanding of digital representation as a crucial informational medium.The results served as vessels for disseminating archaeological knowledge and as powerful tools for dissecting the structural intricacies of ancient environments. To achieve this, a highly specialized cognitive process was required to elucidate both the tangible and intangible elements within the ontological framework. The introduction of the interoperable approach at the archaeological site of Villa dei Quintili in Rome served as a prime example of the critical function of digital models able to interpret, disseminate, and preserve our cultural heritage accurately. It proved instrumental, both theoretically and practically, in transferring geometries and information for diverse analytical purposes, significantly enhancing their effectiveness through a thoughtfully selected range of exchange formats for preservation and structural analysis. Finally, the study introduces a methodology for translating digital models into advanced mediums, including extended reality (XR), pushing the boundaries of heritage preservation in the digital age.DOI: https://doi.org/10.20365/disegnarecon.30.2023.25

Durante la década de 1990 se implementaron en Argentina políticas neoliberales que incrementaron el desempleo y la pobreza. En ese contexto una parte de la población -que ya era pobre - se empobreció aún más y recurrió a la recolección informal de residuos como estrategia de supervivencia. En esa situación el espacio público se convirtió no sólo en un lugar de tránsito sino de reproducción de las condiciones de vida, y, dado que la actividad se realiza a la vista de todos, debieron implementar "fachadas" para acreditarse frente a los demás. Por ello el objetivo de este artículo es analizar las de interacciones que entablan con otros actores y cómo utilizan el espacio público los recolectores informales en la ciudad de Mar del Plata, una ciudad balnearia e intermedia de la Argentina. Las fuentes y la metodología usadas para realizar la investigación fueron la entrevista en profundidad y la observación, además de periódicos de la Ciudad. Los resultados más importantes versan sobre las técnicas que utilizan para acreditarse frente a sí mismos y frente a los demás.

Non-invasive mechanical ventilation (NIV) was originally used in patients with acute respiratory compromises or exacerbations of chronic respiratory diseases as an alternative to intubation. Over the last thirty years NIV has been used during the night in patients with stable chronic lung diseases such as obstructive sleep apnea, the overlap syndrome (COPD and obstructive sleep apnea), neuromuscular disorders, obesity-hypoventilation syndrome and in other conditions such as sleep disorders associated with congestive heart failure.In this review we discuss the different types of NIV, the specific conditions in which they can be used as well as the indications, recommendations, and evidence supporting the efficacy of NIV. Resumo: A ventilação mecânica não invasiva (VNI) foi originalmente usada em doentes com insuficiência respiratória aguda ou em exacerbações de doença respiratória crónica, como uma alternativa à intubação. Nos últimos trinta anos, a VNI tem sido usada durante a noite, em doentes com doenças pulmonares crónicas estáveis, como a apneia obstrutiva do sono, a síndrome de sobreposição (DPOC - doença pulmonar obstrutiva crónica - e apneia obstrutiva do sono), disfunções neuromusculares, síndrome de hipoventilação e obesidade, e em outras doenças como os distúrbios do sono associados a insuficiência cardíaca congestiva.Nesta análise discutimos os diferentes tipos de VNI, as condições específicas em que cada um deles pode ser usado, assim como as indicações, recomendações e a evidência que comprova a eficácia da VNI.
