Aquaponics, a practice that combines aquaculture and hydroponics, offers a sustainable alternative for food production in areas with limited water resources, such as some regions of Peru. However, properly managing water parameters, which are essential to maintain the system's balance, remains a significant challenge. In this context, the study aimed to design and implement a remote monitoring system based on IoT to measure and control critical water parameters in an aquaponic fish farm in Tacna, Peru. The methodology included the development of a hardware infrastructure with pH, turbidity, temperature, and water level sensors, connected to an ESP32 LilyGO microcontroller with MQTT communication and equipped with a GSM/3G modem (SIM7000G). Additionally, software was designed for data collection, transmission, and cloud storage, enabling real-time monitoring and automated actions. The res...

This article develops a robust platform for remote process management.JAVA language is used as a programming language at three levels of development: Control Servers, Web Server and Web Clients. The interaction with the control servers will be through the serial port and/or parallel port depending on the requirement. Thus we can interact with any specialized control device: A microcontroller, a PLC (Programmable Logic Controller), a DSP (Digital Signal Processor) or sophisticated sensors that send data through the aforementioned ports, theLocal network of Control servers ensure the reliability and proper functioning of our processes.The exit door to the Internet will be the "Web Servers", which serve clients; Such a client does not have direct access to the system, until it has verified its privileges. The information thatjourney through the Web is encrypted. Using a microcontroller we w...

This study aimed to evaluate an inventory policy for high-turnover medical supplies in tertiary healthcare centers located in areas with difficult access. The research was applied in nature, featuring a non-experimental design, descriptive scope, and quantitative approach. A clinic in the municipality of Leticia, a region in Colombia known for its challenging access, was selected as the case study. Stochastic scenarios were assessed in comparison with the clinic’s current context, utilizing the stochastic (S, T) method as it met the necessary characteristics for the healthcare center. The results concluded that this method significantly optimizes costs, primarily due to variations in policy parameters such as economic order quantity, order frequency, safety stock, and service satisfaction levels.

Objective: To assess glycemic control in patients with diabetes mellitus (DM) seen in live consultation or remote consultation, and to identify factors associated with variations in glycated hemoglobin (HbA1c) values. Materials and methods: We did a retrospective cohort study that included patients >18 years old who were seen in live consultation or remote consultation because of DM in Alberto Sabogal-Sologuren National Hospital, during June 2021. Clinical data from electronic clinical records were obtained, including baseline and at 11-month follow-up HbA1c values. We used Poisson regression with robust variance for calculating relative risk (RR) and 95% confidence intervals (CI), for identifying factors associated with ≥0.5 HbA1c variations during follow-up. Results: Four-hundred and sixteen patients were included, their mean age was 62 years, 57.2% were female, and 68.5% had remo...

In the present time the mine clearance by the security forces is considered a job with a high mortality rate. The purpose of this article was to develop and implement a robotic platform remote control for identification of antipersonnel landmines in various fields; starting from an obstacle avoidance system, for this propose we using the algorithm VFH (Vector Field Histogram) through the LabVIEW Robotics software. The results have showed that the caterpillar type traction system allows better movement, more grip in all fields compared to the type wheel drive system, plus 87.5% accuracy in identifying mines was obtained from a set of 8 different materials, compared with the currently used system MICRONTA 4003. The implemented system contributes to the detection of dangerous objects on different grounds, becoming an alternative to reduce mortality rates in demining.

Telemedicine describes the electronic delivery of medical data for diagnosis, treatment and medical education to the patient at home through the use of information and communication technologies. In just a few weeks, the current global situation related to COVID-19 has generated unprecedented pressures on the health system and transformed the practice of palliative care. The National Center for Pain Control and Palliative Care's home visiting program adopted the teleconsultation modality in March 2020 and a pilot plan for evaluating telemonitoring technology was established. During the initial evaluation period between March and July 2020, a physician specializing in Palliative Medicine reviewed the vital signs within 24 hours of transmission and conducted a teleconsultation of the patient allowing analysis of the data received. A total of 14 patients were monitored for an average of 10....

The implementation of remote working in Spain has been accelerated by the COVID-19 healthcare crisis. This situation, which has quickly become a reality, has given rise to significant legislative changes regarding post-pandemic remote working, which were undoubtably necessary given the few regulations that were in place. However, certain questions have arisen regarding interpretation which have yet to be fully resolved.This article analyzes the main benefits of working from home (such as flexibility and work-life balance), as well as its challenges for companies and workers. For example, the need to have timekeeping records, guarantee the right to digitally disconnect from work, ensure corporate control and occupational risk prevention. It also looks at some practical solutions that companies are applying.Finally, the article briefly examines the main features of international remote wor...

La detección de barcos usando imágenes satelitales ópticas es una tarea muy importante para el campo de la seguridad marítima, ya sea en la búsqueda de embarcaciones perdidas o en el control marítimo de tipo comercial o militar. A esto se suman los avances en el campo de visión por computador, especialmente en el uso de modelos basados en inteligencia artificial, los cuales, permiten construir sistemas de detección robustos y más precisos. Sin embargo, los escenarios geográficos, propios de una imagen satelital, limitan el desarrollo de este tipo de sistemas ya que requieren de la disponibilidad de un gran número de imágenes en diferentes escenarios. En el presente trabajo se propone un nuevo enfoque para la Detección de Barcos uti- lizando dos nuevos conjuntos de datos etiquetados con cuadros delimitadores horizontales. Así mismo, se presenta una nueva herramienta de etiqu...
