This research has three aspects in relation to Education Innovation for the Sustainable Development: (i) changes in the philosophical, epistemological and didactic framework of education, (ii) the questioning of the new functions of the higher education and (iii) the evaluation and inclusion of an Andean Amazonian Cosmo vision and rationality in the University environment. One of the transformer results of this experience was to put into practice complex, transdisciplinary, phenomenological and hermeneutical education researches that promote an intercultural dialogue. It was developed in the «Diplomado en Biodiversidad y Saberes interculturales» (Diploma course in Biodiversity and Intercultural Knowledge) that took place in the San Martin region in the Quechua Lamas communities. It was organized by the Instituto Peruano del Pensamiento Complejo Edgar Morin -IPCEM (Peruvian Institute fo...

Agriculture is one of the most important economic activities in Peru. Furthermore, the Peruvian mango is the most important fruit as an export product on the European market due to its good quality. Three varieties of mango are cultivated in Peru: Haden, Kent and Tommy Atkins, each of them presents different characteristics; however, the production of this fruit is affected because manual processes are still used for its production, which generates a delay in the process due to the inaccuracy of the labour. The present study aims to develop the simulation of an automated grading system for Peruvian mangoes based on computer vision. On the other hand, to establish the process development, the transfer learning principle was analysed and a flow diagram of the system was made. The simulation of the system environment was obtained through the Factory IO software, together with the image proc...

Lemon exports are of great influence in Peru, since there is a great demand from countries such as the USA, Belgium and Holland. For this reason, the agricultural sector is one of the essential factors for the economic development of the country, since it generates S/29,553 million annually throughout the national territory. On the other hand, Peru offers two types of lemons, for example: the Tahitian lemon and the subtle lemon; however, due to its characteristics, the Tahitian lemon is the one that is sent as an export product worldwide. Currently, the selection process of this fruit is done manually, since there are not enough industrial optimizations in its process. Therefore, the present study aims to carry out the simulation of an automated grading system for Tahitian lemon based on computer vision. The selection parameters for the image processing were established as the levels of ...

Fish larvae counting is a technique applied in aquaculture to determine the efficiency of the induction stage and to know the number of fertilized larvae. For this reason, the research aims to improve the count of larvae under 3 fundamental pillars: precision, error and time. For this, we carried out an experimental investigation under a completely randomized design with two counting systems: traditional and artificial vision; each one with 10 repetitions, with 2000 larvae; Later, we carried out the count by means of artificial vision using a camera that captured images of a fish tank with moving fish. The results show that the proposed method is feasible for counting larvae, with 92.65% accuracy, 7.41% error and an average time of 61 seconds per repetition in relation to the traditional counting system: accuracy 64.44%, error 35.61% and time 2009.3 s. The developed system can be replica...

Pokémon Double Battles present a complex decision-making environment that has traditionally relied on manual data analysis. This paper introduces an automated system leveraging computer vision and deep learning to extract structured gameplay data from battle footage. Our approach integrates You Only Look Once (YOLO) for Pokémon sprite recognition along with Tesseract-based optical character recognition (OCR) for extracting move and status text. The study introduces a custom-built image dataset generated through the augmentation of publicly available Pokémon sprites, which is then used to train a YOLO model for sprite recognition. The system was tested across multiple controlled and real-world gameplay scenarios, achieving high accuracy in Pokémon recognition and action tracking. Additionally, a JSON-based gameplay notation system is proposed to structure battle sequences, thus improv...

In Ecuador, the Andean highlands ecosystems, also known as páramos, are essential for producing water for human consumption and irrigation. Some páramos in the country are managed by indigenous communities that have contributed to their conservation through principles of reciprocity, territory and culture. However, these community-led initiatives are often marginalized by techno-scientific discourses and visions of water as promoted by public authorities as well as international experts working on these issues. Faced with these limitations, local water justice movements advocate for a more politicized approach that aims to shed light on the unequal distribution of benefits, access and control over water, as well as the tensions surrounding water rights, knowledge and cultural practices. This article draws on a case study in the communities of Cangahua, located in the northern highlands...

Este documento presenta un sistema de operación asistida de un brazo robótico para el posicionamiento cerca de un artefacto explosivo seleccionado por el usuario a través de la visualización de las cámaras en la pantalla. Dos cámaras no convergentes montadas en el brazo robótico en configuración cámara en mano proporcionan las coordenadas tridimensionales (3D) del objeto que se está siguiendo, utilizando una técnica de reconstrucción 3D con la ayuda del algoritmo de desplazamiento medio adaptativo continuo (CAMSHIFT) para el seguimiento de objetos y la coincidencia de características. La cinemática inversa del robot se implementa para situar el efector final cerca del explosivo, de forma que el operario pueda realizar la operación de agarrar la granada con mayor facilidad. La cinemática inversa se implementa en su forma geométrica, reduciendo así la carga computacional....

Objective: To evaluate the history of cataract and vision problems in people over 50 years of age in Peru. Methods: Secondary database analysis of the Demographic and Family Health Survey (ENDES) 2016. We included 7970 adults over 50 years of age. We evaluated the indicators of interest at the national and regional level. Likewise, we analyzed factors related to these events using a multivariate Poisson model. Results: 13.6% (95% CI: 12.8-14.3%) had a history of cataract, 20.4% (95%CI: 19.5-21.3%) had long-distance vision problems. (LDVP) and 29.4% (95%CI: 28.4-30.4%) of short-distance vision problems (SDVP). In the multivariate model, we observed that people with a history of high blood pressure, a history of diabetes, and older age groups were significantly more likely to report a history of cataracts and vision problems. We also observed that people with a better economic status had a...
