The research was aimed at implementing a permanent monitoring system of the parameters present in the water of fish ponds and sending alerts to managers when abnormal parameters that may affect fish farming are captured, all this developed with IoT technologies (Internet of Things). The system consists of a device and a web application that communicate with each other, the device developed with Arduino will capture the parameters (temperature and pH) present in the water of the ponds by sensors, this device will send and store the data remotely to the database connected to the web application, in this application you can view all the captured parameters and also you can modify the configuration of the device. It will also be notified via SMS and phone call (cell phone) to the administrator of the ponds, in case of capturing and/or detecting anomalous values present in the water, the phone call will not have any voice message, instead the SMS text message will have the captured values, seeking in this way that the administrator can make decisions regarding the state of the water and otherwise the crop.

Currently, with the constant demand growth of devices connected to the internet many times we see collapses in the network, hence surged the Software-Defined Networks (SDN), a new paradigm of nets and also a concept called load balance is added that in few words improves the response time of the servers which we are connected using different mechanisms according to need. This research addresses the topic of Load Balancing in Software-Defined Networks using Quality of Service algorithms to ensure and optimize the proper functioning of the network in terms of velocity and data traffic. The main objective is to perform and apply these algorithms in the SDN controller where the best route of all the links in the network is located to circulate the desired traffic between the desired hosts; it should be noted that the network is simulated in a virtual environment, with a tool called Mininet, within which all the network parameters are configured and can be attached to the SDN controller. In short, the algorithms were successfully applied and is appreciated the big difference between the before and after of the experiments, the improvements in the network is due to the delay time and the bandwidth according to the standards meets with Quality of Service; with the tabulation of all these data was created graphs where we see the trend of the values in the network states. As a conclusion we have that the quality of service algorithms are a good option for the realization of load balancers in this type of networks, whatever the type of data that manages the network, the improvements will always be noticed in the functioning of the network and the response times of the request made to the different servers.

Ahuyama cream (Cucurbita moschata) contains a large amount of nutrients, among which a high amount of minerals and carbohydrates stands out. The spray drying technology corresponds to a technique by which water is evaporated from a liquid or semi-liquid phase for its conversion to a solid phase (dry product) with a low moisture content, being universally used in the agri-food area in order to to improve the preservation, stability, storage, transportation, among other characteristics of this class of products. For the development of this research, we evaluated the acceptance of three formulations of ahuyama cream with 50 untrained panelists with an age range between 18 and 50 years, of different genres, through a sensory acceptance test, which provided the formulation selected for the development of this research. The objective of this work was to evaluate the drying conditions of the ahuyama cream by the Spray drying method, using Maltodextrine as an encapsulant at different concentrations (8, 12 and 16 %), at different inlet temperatures of the drying air (170°C, 185°C and 200°C). Determining the effect, they have on moisture, solubility, performance, and color of the ahuyama cream powder. The development of this grade work, as a result, shows that the variables of responses studied (humidity, solubility, yield and color), were affected by the variation of process conditions (temperatures and maltodextrine concentrations), evidenced in the results of samples 9 and 3. Concluding that the favourable conditions for obtaining a product with the best xiii conditions of the response variables evaluated (moisture, solubility, yield, color) were at an input temperature of 200°C and a maltodextrin concentration of 16%. However, it is recommended that the formulation (Table 7) used be equal to the one worked in this research. Because the acceptance of tasters for formulation 3.

The orientation of this project is focused on designing and developing a mobile application, which functions as a tool to strengthen brain skills in the face of Alzheimer's disease and cognitive impairment in older adults in the P-5 neighborhood of the city of Monteria. Through a survey conducted to the population, it was possible to identify different variables linked to cognitive impairment, as well as the knowledge about the disease and how adults are related to technology; thanks to this, the lack of a support tool to treat diseases and conditions of this type was evidenced. The methodology used for the design and implementation of the App, is the RUP methodology, this methodology allows an effective and structured development of the application, taking into account the realization of a series of phases during the development of the project. The application is called ActivaMente, and is developed in the Android operating system, using ReactNative. For data storage, the database was implemented in Firebase

In this investigation project, we wanted to reduce the anxiety of young people in their university stage, through an application prototype, which combined the therapies, considering the impact of the changes they present both at a social, economic and cultural level. According to the National Institutes of Health, between the ages of 13 and 18, about 1 in 3 adolescents may develop an anxiety disorder. To make it, The ISRA B instrument was used, Inventory of Anxiety Situations and Responses, which assesses the cognitive, physiological, and motor responses of anxiety, giving as reference certain situations. In addition, therapies such as cognitive behavioral therapy were implemented, mindfulness-based cognitive therapy, and theotherapy through an application prototype. It was used a sample of 68 students from the faculty of industrial engineering, first and ninth semester, from the University of Cordoba of the period 2020-2. In addition, pretended to make a contribution to the way in which non-pathological anxiety and be treated in a simple way, without so much time demand, and without the need for a high economic resource, through the combination of the therapies mentioned above, without pretending to replace the work of specialized personnel and the methods used in psychology

La piña (Ananas comosus) es una fruta tropical que pertenece a la familia Bromeliáceas, tuvo su origen en Sudamérica. Su composición nutricional la han convertido en una fruta completa, esta posee un gran contenido en vitaminas (A y C) y minerales que son importantes para una óptima nutrición. De este fruto el peso de la cáscara corresponde al 41% de su peso total, un 6% el corazón, un 20% la corona y solo el 33% es pulpa. La producción y el procesamiento en aumento de esta fruta, representa un aumento en la generación de la biomasa (cáscara de piña), lo cual favorecería a la reducción de la vida útil de sitios de disposición final, a la proliferación de vectores que causan enfermedades, y en general, a problemas en la salud pública, cuando estos no presentan un manejo adecuado puesto que el material vegetal suele ser propenso a la descomposición microbiana. El objetivo de este trabajo fue evaluar el efecto de la temperatura y velocidad del aire caliente en el secado de cáscara de piña por el método de bandeja para la obtención de harina rica en fibra. Se determinó la pérdida de humedad con respecto al tiempo, empleándose dos velocidades de flujo de aire (1 y 2 m/s) y tres temperaturas de proceso (50, 60 y 70°C), y se aplicó la segunda ley de Fick para determinar difusividad efectiva del agua (D_eff), igualmente se determinó la energía de activación ( Ea) aplicando la ecuación de Arrhenius. Como resultado de la caracterización bromatológica se encontró que las cáscaras de piña y la harina obtenida tienen buen contenido de fibra, la cual disminuyó conforme aumentaba la temperatura de proceso y fue mayor para el tratamiento 1 con un valor de 54,10 % en base seca, las temperaturas de proceso no afectaron los contenidos de ceniza, ni la capacidad antioxidante, así como tampoco influyeron en las propiedades tecnofuncionales, dado a que las harinas obtenidas no presentaron diferencias significativas en dichos parámetros. Se obtuvo que al aumentar la temperatura del proceso de secado disminuyó significativamente el tiempo de secado, necesitando menos tiempo para finalizar el secado a la temperatura de 70ºC que a temperatura de 60 y 50ºC.

La contaminación del aire no debe verse solo como una problemática ambiental, sino que está directamente relacionada con la calidad de vida de la población, por lo cual se evidencia entre otras situaciones, con el aumento en la frecuencia de aparición de enfermedades respiratorias y por consiguiente el incremento en el ausentismo laboral y escolar. De igual manera, además de la afectación en la salud humana, también afecta la vida vegetal y animal, así como algunos materiales, en el primer caso causando entre otros, afecciones al sistema respiratorio y obstrucciones que impiden procesos vitales como la fotosíntesis en el caso de las plantas (IDEAM, 2012).
