Abstract Background: The purpose of this study was to characterize school-based adolescent sexuality interventions and to compare the outcomes assessed and the results obtained according to the approach used and the country’s income level. Method: A systematic review was conducted in accordance with PRISMA recommendations. The search considered SCOPUS, Web of Science, PubMed, ProQuest and Biblioteca Digital Uchile databases. We included studies between 2010 and 2022 that evaluated school-based sexual health interventions targeting adolescents and that were randomized controlled trials, quasi-experimental designs, or post-hoc studies. Results: 527 studies were identified, 24 were selected for this review. Eight belonged to the comprehensive approach, 15 to the risk approach and one to the abstinence approach. Of all interventions, 16 were conducted in high-income countries, four in upper-middle-income, two in lower-middle-income and two in low-income countries. Discussion: Outcome measures do not appear to be related to income levels. In addition, some interventions self-defined as comprehensive showed evaluated outcomes corresponding to measures studied by interventions based on a risk approach....

Wall polygon retrieval from architectural floor plan images using vectorización and Deep Learning methods

a que éstos se crean usando herramientas CAD, la distribución a clientes suele ser a través
de imágenes rasterizadas que pierden toda información geométrica y topológica de las intrincadas

Automatic plan analysis is an area within computer vision that has sustained significant growth in the last five years due to increasing industry interest in software development for the construction and design sector. Although these are created using CAD tools, the distribution to clients is usually through raster images that discard all geometric and topological information of the intricate configurations of walls, beams, slabs, elevations, or furniture. Conversely, even if a digital model exists, there is no certainty that the information and metadata are correct; both walls and beams may be drawn in the same way, in the same layer, and with the same labels. While multiple processing algorithms have been designed, object retrieval is particularly complex, as no industry design standard exists. Additionally, floor plans come in diverse styles, shapes, and with annotations that are specific to each architectural and engineering office. Consequently, retrieval methods reliant on a particular style lack broad applicability and adaptability. Instead, data-driven approaches have demonstrated superior performance by leveraging plan images to infer intricate rules for tasks like segmentation, vectorization, and classification, among others. For these reasons, this thesis examines the progression of methodologies employed in the analysis of such documents, transitioning from rule-based approaches to those bolstered by deep learning technology, distilling the typical tasks, techniques, and challenges. As an object of study, we developed a U-Net segmentation model to retrieve wall polygons from complex plans of Chilean residential buildings, contributing both a new dataset and an image processing method, as well as a comparison baseline for future work. The segmented output was vectorized by choosing a deep learning-based method retrieved from the state-of-the-art review, allowing us to obtain the wall polygons automatically from a raster plan. Our work is entirely open-source and publicly available to the community https://gith ub.com/MLSTRUCT/MLSTRUCT-FP. We believe that it will benefit researchers and developers within the construction and design industries, which have experienced a complex global scenario of productivity and growth, making evident the need for new tools to bridge the technology gap, mitigate losses, and reduce costs....
