A cloud-native application is a software specifically designed to run in the cloud, focusing on distributed, elastic, horizontally scaled, and microservice-based architecture with autonomous deployment. These applications are designed with cloud-native web architectures, operate on an elastic self-service platform, and stand out because of their resilience and elasticity. Continuous software engineering integrates requirements engineering, development, and operations in a continuous loop with reciprocal feedback to produce quality software. The present work proposes to design and implement a cloud-native application applied to the SIGCON case study from a continuous software engineering perspective. It uses the CaaS cloud service model, applies the BFF pattern in software construction, containerizes the frontend, backend, and storage, and presents the results.

To adjust the parameters that influence the appearance of defects in the steel in the continuous casting mold, a particle swarm optimization algorithm (PSO) was developed using process models. The study considered multiple objectives with multiple restrictions and the results were compared with those reported by a teaching-learning-based optimization algorithm (TLBO). We conclude that the PSO has a good capacity to determine the parameters of the mold, and with it, it is possible to achieve an optimal solution without requiring great computational efforts.

En el ensayo se revisa cómo las ciencias sociales actuales hacen uso del concepto paisaje como categoría analítica en la investigación territorial. El estudio del paisaje implica un proceso de multidisciplinariedad importante, en el que la historia funge como eje fundamental al representar la dinámica de las estructuras y morfologías sociales y ambientales que van dejando huellas en los espacios. Los paisajes son ventanas a los diferentes modos de ser y hacer en la historia, por lo que son una herramienta con grandes posibilidades para comprender las súbitas transformaciones de las regiones contemporáneas. La discusión que se propone en este sentido, comienza por encontrar la posición teórico-metodológica de los estudios del paisaje en las ciencias sociales, en específico con el enfoque cultural en geografía.

Successful results of all types of professional activities largely depend on the quality of training. At present, however, the acquired knowledge does not guarantee a university graduate stability of success throughout his/her career. Thus, the concept of lifelong education was gradually formed. From the previously established stereotype “education for life”, society is moving to the “education throughout life”. The traditional division of a person’s active life into the period of professional activity and study is blurring. There is a need for a transition to continuing professional education throughout life. One of the most important tasks for the management is to ensure the continuous development and survival of the organizations. Such a task is also vital for the institutions of additional professional education. With the transition to the newly established market relations...

Las enfermedades cardiovasculares (ECV) se encuentran entre las que presentan las tasas de mortalidad más altas, y están surgiendo varios dispositivos portátiles para el monitoreo continuo como complemento a los procedimientos médicos. La monitorización de la presión arterial (PA) en dispositivos portátiles, para que sea continua, debe realizarse de forma no invasiva, por lo que involucra la fotopletismografía (PPG), una tecnología que ha sido ampliamente estudiada en los últimos años como una solución no invasiva para la estimación de la PA. Sin embargo, la adquisición continua de datos en un sistema portátil sigue siendo un desafío, una de las razones es el ruido causado por el movimiento, el uso correcto de la señal PPG y el método de estimación a utilizar. Este artículo revisa los avances en la estimación de la presión arterial basada en fotopletismografía, cen...

Influenza is a highly contagious disease. There are some historical descriptions of this condition by ancient Greek physicians, and the etiological agents have been known only for the last eight decades. The causative agent is the influenza virus, which has three main types: A, B, and C. Type A is capable of circulating within many different biological reservoirs, including humans, swine, and birds. It also has high genetic variability, which allows it to have minor antigenic drifts or mutations which are responsible of epidemics in humans. Sometimes changes are quite marked, leading to pandemics.In a globalized world, with more than 6 billion inhabitants, with many social inequities and evident climate changes, influenza viruses are a permanent risk for mankind.Clinical features for the different viral subtypes may vary from subtle infections to full blown and severe, life-threatening f...
