Urban planning is recognized as an interaction between the state and society, which aims to articulate public policies in the territory, facilitating their administration in favor of greater development and well-being of society. However, this interaction becomes complex because consumption demands increase, and the carrying capacity of the urban ecosystem to supply them is exceeded, hindering its sustainable functionality. With this overview, it becomes relevant to study urban planning from a sustainable environmental planning perspective, based on four topics: urban planning, sustainability, resilience, and smart cities, which are developed throughout the document by means of a chronological study. A bibliometric study was used through a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) adjustment to 87 articles, supported by VOSviewer®, which allowed for the construction and visualization of the co-occurrence networks of key words extracted from the selected articles. Likewise, 16 documents more were used for the co-occurrence analysis. The main result is to consider cities with a complex systems approach that works like a gear; the relationship between inter-urban and intra-urban processes is the key factor that allows for an understanding of their synchronization; therefore, deepening of each of these topics is crucial to the ideal of a territorial administration involving time scales and adaptive cycles, allowing for the provision of new tools for concepts such as carrying capacity and the measurement of the ecological footprint.

The Internet of Things (IoT) and its applications are growing simultaneously. These applications need new intelligent devices along heterogeneous networking. Which makes them costly to implement indeed. Platforms and open devices designed for open-source hardware are possible solutions. This research was conducted under an IoT design, implementation, and assessment model for the remote monitoring of pulse oximetry via oxygen partial saturation (SpO2) and heart rate (HR) with low-energy consumption. This study focused on the development of SpO2 and HR measurements that will allow the monitoring and estimation in real time of the user's state and health related to the established parameters. Measurements were acquired and recorded using a remote web server that recorded the acquired variables for further processing. The statistical analysis data allows comparison of the registered data measured with theoretical models. The IoT model was developed use Bluetooth low-energy devices, which comply with low-cost and open-hardware solutions operated via 'HTTP requests' for data transmission and reception from a cloud server to an edge device. Network performance assessment was conducted to guarantee the availability and integrity of the acquired values and signals. The system measured SpO2 and HR variables. The most significant result was to achieve energy consumption 20% lower than that of devices in the market. In summary, the acquired data validation based on the IoT model had a transmission error of 0.001% which proves its applicability in healthcare.

The management of large medical files poses a critical challenge in the health sector, with conventional systems facing deficiencies in security, scalability, and efficiency. Blockchain ensures the immutability and traceability of medical records, while the cloud allows scalable and efficient storage. Together, they can transform the data management of electronic health record applications. The method used was the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology to choose and select the relevant studies that contribute to this research, with special emphasis set on maintaining the integrity and security of the blockchain while tackling the potential and efficiency of cloud infrastructures. The study’s focus is to provide a comprehensive and insightful examination of the modern landscape concerning the integration of blockchain and cloud advances, highlighting the current challenges and building a solid foundation for future development. Furthermore, it is very important to increase the integration of blockchain security with the dynamic potential of cloud computing while guaranteeing information integrity and security remain uncompromised. In conclusion, this paper serves as an important resource for analysts, specialists, and partners looking to delve into and develop the integration of blockchain and cloud innovations.

Urban planning is recognized as an interaction between the state and society, which aims to articulate public policies in the territory, facilitating their administration in favor of greater development and well-being of society. However, this interaction becomes complex because consumption demands increase, and the needs of the community exceed the capacity of the urban ecosystem to supply them, hindering its sustainable functionality. With this panorama, it becomes relevant to study urban planning from a sustainable environmental planning perspective, based on four topics: urban planning, sustainability, resilience and smart cities. The methodology used is based on a bibliometric study through a PRISMA adjustment to 87 articles, supported by VOSviewer® to construct and visualize the co-occurrence networks of important terms extracted from a body of scientific literature. The main result is to consider cities with a complex systems approach that works like a gear, that is, there is a connective element between inter- and intra-urban processes. This relationship is the key factor that allows understanding their synchronization, stating that the deepening of each of these topics is crucial to the ideal of a territorial administration through time scales, by means of adaptive cycles, allowing to provide new tools to concepts such as carrying capacity and the measurement of the environmental footprint.

El presente artículo ofrece una reflexión sobre las posturas metodológicas del construccionismo que integran las tecnologías de la información y la comunicación (tic), entre ellas la WebQuest, objetos digitales de aprendizaje,plataformas e-Learning, entre otras, de gran auge actual, frente a nuevos objetivos y desafíos con visión futurista de la sociedad. Para abrir la reflexión sobre el proceso de enseñanza-aprendizaje se propone un caso de estudio quepermita evaluar cómo el metabolismo de la sala de clases ha cambiado, principalmente por el uso masivo de las tic que brinda al estudiante una metodología de información distribuida en diferentes y variadas fuentes de información, apartando la metodología centralizada que le prepara mediante el aprender haciendo e investigar reflexionando. En el ambiente universitario, la investigación forma parte del quehacer del estudiante convertido inicialmente en auxiliar de investigación y es ahí donde resulta necesario un análisis de los efectos que causan sus investigaciones en el medio sociocultural y productivo en el cual se desenvuelve.El caso de estudio se desarrolla con los grupos de investigación en telemedicina de la Universidad Militar Nueva Granada de Colombia (Tigum) y en Nuevas Tecnologías de la Universidad Santiago de Chile (gint), que durante 2012 y 2013 han realizado un estudio paralelo exploratorio aplicando la metodología “aprender haciendo-investigar reflexionando”, la cual permite evaluar los resultados de investigación y el desarrollo profesional de sus auxiliaresparticipantes. Así, se ha logrado que el 80% de los auxiliares continúen sus estudios de posgrado en maestrías o doctorados a nivel nacional o internacional.Palabras clave: metodología, aprender, hacer, investigar, reflexionar.
