This article presents reflections on thinking and how it can be enhanced to generate projectual memory applied to the creative process. Thus, design situations, although challenging, will not represent an insurmountable peak of stress. The incorporation of Artificial Intelligence in the process provides feedback that encourages the enhancement of projectual thinking. Thanks to the fact that it makes it possible to visualize the process and ideas that allow the designer to manage, and/or create, tools to successfully approach any situation by returning to the thoughts and inputs used. The path to approach empowerment will be like this: review the faculty of thought; next, approach the projectual in the architectonic. Then, with the sections about conceptual and schematic inputs, communication and the creative process, the journey is consolidated.

A study was carried out that seeks to determine the impact of the development of group gymnastic activities by teachers to improve the institutional climate among the teachers of a state educational institution in the city of Lima, therefore, a research was considered based on group work strategies based on gymnastic activities; An investigation was carried out considering a control group and experimental group. Both groups were evaluated on the institutional climate as a pretest; after nine sessions, a posttest was taken fromthe participating teachers; The control and experimental groups were made up of 34 teachers each; The teachers belong to an educational institution in the Lima district of Los Olivos. The results showed that the experimental group had a significant development of the institutional climate; this when comparing the pretest and posttest; while in the control group the institutional climate was maintained; The parameter used to compare for the related groups was T-Student.

The design method is in no way separated from the constructive vision. Aristotle perceived the world as the here-and-now of the idea, which, in its hylomorphism was embodied in matter. The theory of the four causes certifies this. Every event comes from movement, the efficient cause in architecture is necessity; the purpose is to inhabit; the formal cause is the way of thinking and the material cause is the constructive system that supports it. The useful technique is the way of creating architecture in antiquity, and it meant at the same time a knowing-how to think and knowing-how to do, this is what this article discusses about the methods that produce materiality, applied to the Velarde house as an incarnation of Peruvian modernity.

Los modelos clásicos de sistemas de tanques acoplados suelen asumir un factor de fricción constante, lo cual limita su precisión en condiciones reales donde el régimen de flujo puede variar entre laminar, transicional y turbulento. Este estudio propone un modelo no lineal para dos tanques cilíndricos acoplados, en el que el factor de fricción se calcula dinámicamente en función del número de Reynolds y la rugosidad del material. El modelo integra las ecuaciones de energía y continuidad, y se resuelve mediante el método de Euler con paso de integración Δt = 0.01 s. Los resultados muestran que el sistema alcanza un punto de equilibrio (H1=0.2694, H2=0.1384) que coincide con la solución obtenida por Newton-Raphson. Además, el modelo no lineal captura con mayor precisión la dinámica transitoria, especialmente en condiciones de bajo caudal (Re < 4000), donde el factor de fricción presenta variaciones significativas. En flujo turbulento (Re > 4000), f se estabiliza, lo que explica la validez de modelos simplificados en regímenes de alto caudal. Se concluye que la inclusión del régimen de flujo en el cálculo de f mejora notablemente la capacidad predictiva del modelo, siendo fundamental para el diseño de controladores robustos en aplicaciones industriales.

In the district of Mamara, province of Grau, Apurímac, a critical problem was identified in the drinking water distribution network, characterized by obsolete infrastructure, deteriorated pipes, constant leaks, and irregular pressure. This situation limited the system's capacity to adequately meet the population's water demand and affected service quality. The study aimed to evaluate the condition of the hydraulic network and its operational capacity, also considering the state of water sources, such as springs and wells, which exhibited irregular flow rates and contamination levels. The research was developed under a hypothetical-deductive approach, using fieldwork, interviews with users, and analysis of consumption and supply records. The results revealed deficiencies in water catchment, conveyance, and storage; the presence of fecal coliforms in distributed water; insufficient pressure in homes located in higher areas; and the absence of treatment. It was concluded that it is necessary to implement a feasible technical proposal to optimize the system, considering the available resources, and to incorporate control, treatment, and maintenance measures.

: Cardiovascular diseases (CVDs) are the leading cause of mortality worldwide, which is why technologies such as machine learning are being used to improve early diagnosis and clinical decision-making. The objective of this study was to develop a predictive model using the ExtraTreesClassifier algorithm to estimate CVD risk from clinical data. A public Kaggle dataset with 3,652 records and 15 variables was used. Preprocessing included cleaning, normalization, and balancing using SMOTE. The model was trained in Python with scikit-learn, starting with 10 trees (n_estimators = 10), achieving an accuracy of 84%. The model was subsequently optimized to 310 trees to achieve a better accuracy of 88%. In addition, a web interface with an interactive form was developed, aimed at non-technical users. The results showed robust performance and balance between the "Yes heart attack" and "No heart attack" classes. In conclusion, the ExtraTreesClassifier model proves to be a useful tool for cardiovascular risk stratification, providing clinical value and facilitating more informed decisions for healthcare professionals and patients.

In Los Cedros, Chorrillos, sandy soils presented low cohesion and poor stability, which hindered their use in construction. This problem was exacerbated by rapid urban growth, increasing the demand for buildable land. In response, the following question arose: Is it possible to improve these soils using sustainable, effective, and accessible alternatives? This study aimed to address this question through viable solutions that promote urban development without significantly increasing costs. An experimental method was applied to evaluate how recycled polyethylene terephthalate (PET) and fly ash modified the geotechnical properties of the soil. Samples with different additive proportions were prepared and tested under controlled conditions. The design was quasi-experimental, quantitative, and multifactorial, keeping variables such as optimum moisture and compaction constant. The results showed improvements in load-bearing capacity (CBR), with an increase of 10.4%, as well as favorable changes in particle size distribution (changing from CH to ML), plasticity indices, and dry density, compared to natural soil. These variations demonstrated the potential of using a combination of recycled PET and fly ash as a technical, economic, and sustainable solution for improving poor-quality soils, thereby contributing to responsible urban development in vulnerable areas.

Concrete presented technical limitations, such as low tensile strength, shrinkage, and shear resistance, which reduced the service life of structures. Its limited workability hindered placement and compaction, further compromising its performance. In this context, the question was posed: How could the structural performance of concrete be improved in light of its mechanical limitations by applying graphene? Therefore, the main purpose was to evaluate the influence of graphene as an additive in concrete and to assess changes in its mechanical properties. A quasi-experimental design with a quantitative approach was applied. Flexural and compressive strength tests were conducted at 7, 14, and 28 days of curing, along with the slump test using the Abrams cone to analyze workability. The results showed that the addition of 3% graphite powder increased the compressive strength of the concrete, reaching 211.00, 274.00, and 302.00 kg/cm² at 7, 14, and 28 days, respectively, exceeding the design strength in the latter case. It was concluded that the correct determination of the graphene percentage for mix design was crucial, achieving significant improvements in the mechanical specifications of the concrete.

This article deals with the environmental/ecological Humanities in Peru and its relationship with complexity. For this purpose, a specialized bibliographic search was carried out. The review concludes that although environmental/ ecological humanities are not explicitly developed in Peru to date, there are contributions from the perspective of interdisciplinary and transdisciplinarystudies, especially from literature, the arts, environmental history and forestry philosophy. Some of the hybrid disciplines that are considered components of the environmental/ecological humanities are also developed, although they are not manifestly recognized as contributions towards this field of transdisciplinary studies. The complexity sciences with their orientation of indeterminacy, non-linearity, the study of undecidable and non-trivial problems enriches the understanding of life in general and therefore enriches the framework of contents and action of the environmental/ecological humanities. The environmental/ecological humanities have an important role to play in the face of the challenges of the civilizational crisis and specifically the ecological crisis through the emotional, spiritual, cultural, discursive and action support and mobilization of people and groups for the design and implementation of transitional and regeneration alternatives in terms of transmodernity and complexity.
