Fotogrametría, modelamiento tridimensional y drones en arqueología. Segunda parte. Documentación, registro y modelamiento fotogramétrico de sitios arqueológicos
(Pontificia Universidad Católica del Perú, 2025-03-17) Castillo Butters, Luis Jaime; Barrera Yaranga, Héctor
The second part of this paper focuses on the process of 3-D photogrammetric modelling applied to archaeological sites. A discussion of the three phases—planning, recording and processing of drone and drone-less photogrammetric documentation, is followed by a review of six site-recording strategies as determined by the capacities of the equipment used, the characteristics of the sites that are being modelled, and their geographical and topographic setting. These strategies are based on the documentation of over a thousand sites in all Peru, as well as on the various recording requirements in terms of the desired outputs.
Diseño de lenguaje mejorado con IA -ChatGPT: análisis bibliométrico y usos potenciales en la conservación y restauración de ecosistemas tropicales
(Pontificia Universidad Católica del Perú, 2025-05-05) Reyes Palomino, Smith Ervin
ChatGPT, in line with other established artificial intelligence systems, emerges as an advanced tool based on OpenAI's GPT model. This study focuses on exploring its applicability in the conservation and restoration of tropical ecosystems. A bibliometric analysis dissects the main characteristics, learning systems, and potential applications of ChatGPT. Questioned about its groundbreaking potential in the conservation and restoration of tropical ecosystems, ChatGPT outlines applications in assessment and planning, education, monitoring and rapid response, interaction with field tools, and policy support. Although ChatGPT does not inherently provide scientific support, subsequent analysis confirms that its proposals align with current trends in conservation and restoration. When using tools like ChatGPT in scientific contexts, researchers should adopt a critical approach, verifying the provided responses. Additionally, we underscore the need for further research on the ethics of implementing artificial intelligence in conservation and restoration domains.
Saberes y actitudes ecológicas: entre la experiencia vivida, la escuela y las redes sociodigitales
(Pontificia Universidad Católica del Perú, 2025-05-05) Limachi Pérez, Vicente
The article describes the influences of family, school, and sociodigital networks on the construction of environmental awareness among secondary school students in urban and rural schools in the department of Cochabamba, Bolivia. Using a mixed-methods approach—combining surveys, observations, and interviews—data were collected on the environmental knowledge and attitudes of students in three schools. The results revealed that students' environmental concerns vary depending on their surroundings: air pollution in urban areas, water scarcity and contamination in rural Andean regions, and forest fires in the tropical region. Students prioritize the internet (especially Google, YouTube, and TikTok) as their main source of information on environmental issues at the local, national, and global levels. Their reliance on these sources is linked to the speed and multimodal formats they offer. Visual content such as photos, videos, and infographics shapes their perceptions and emotions regarding issues like animal abuse and species extinction. Despite isolated initiatives such as school gardens or orchards, schools do not effectively integrate environmental education into the curriculum, which limits its formative impact. In conclusion, the article highlights the need to strengthen the role of formal education, based on the interaction between family, school, and sociodigital networks, to enhance learning and awareness on ecological issues. It advocates leveraging the potential of sociodigital networks to foster critical awareness and bridge the gap between acquired knowledge and pro-environmental practices, in order to move toward a sustainable relationship with the environment.
Prácticas de la basura y consumismo ¿Un habitus?
(Pontificia Universidad Católica del Perú, 2025-04-25) Cirett Galan, Diana Blanca
The relentless generation of urban solid waste, driven by the population growth of the last century and current consumption-disposal practices, represents a global municipal challenge due to its harmful effects. Its consequences impact various dimensions: health, public space, the environment, and society, among others. A comprehensive study was conducted in Guaymas and San Carlos, Sonora, Mexico, from 2019 to 2022, with the general objective of understanding how the meanings and practices around waste are shaped by gender identity, social class, sense of belonging, and public management in both public and private spaces. This article focuses on how consumerism affects the everyday waste-related practices of men and women in public spaces. The methodology was qualitative and descriptive, using the ethnographic method over five and a half months, with techniques such as observation, casual conversation, and semi-structured interviews conducted with ten informants and four key subjects related to urban solid waste. The findings revealed gender, social class, and belonging-related components connected to waste practices, as well as a differentiation of habitus between the two populations. In one group, there is a tendency to dispose of waste in public spaces, driven by habitual consumerism. This interaction is shaped by cultural, attitudinal, and public management factors—the latter influenced by the lack of policies that encourage individuals to adopt more responsible waste practices.
