    The teaching of Chemistry often becomes automatic and not very dynamic. Chemical concepts require scientific thought processes, being abstract for students (men and women). Therefore, it is important to apply educational resources that promote motivation and interaction with them for meaningful learning. The main objective of this study is to analyze the degree of students' acceptance towards augmented reality technology. The sample was intentional non-probabilistic (N = 100), composed of students of the fifth grade of the pre-university secondary level, in the subject of Chemistry, from the cities of Santiago and Santo Domingo in the Dominican Republic. The instrument applied was the technology acceptance model (TAM), created by Davis in 1989. The results obtained reflect a high degree of acceptance of the augmented reality technology by the participating students to learn about the electronic distribution of the elements of the periodic table. Likewise, the students consider that it is useful and very user-friendly. In summary, augmented reality technology enhances the understanding of chemistry concepts, helps to make classes more dynamic and facilitates the teaching of abstract concepts in a chemistry class, through the enjoyment of interacting with the enriched object in augmented reality format.La enseñanza de la Química, muchas veces, se torna automática y poco dinámica. Los conceptos químicos necesitan de procesos de pensamiento científico y pueden resultar abstractos para los estudiantes (hombres y mujeres). Por esto, es importante aplicar recursos educativos que promuevan la motivación e interacción con los mismos para los aprendizajes significativos. El objetivo principal de este estudio es analizar el grado de aceptación que se produce en los estudiantes hacia la tecnología de realidad aumentada. La muestra fue no probabilística intencional (N = 100) y estuvo compuesta por estudiantes de quinto grado del nivel secundario preuniversitario de la asignatura de Química en las ciudades de Santiago y Santo Domingo de la República Dominicana. El instrumento aplicado fue el modelo de aceptación de la tecnología (technology acceptance model [TAM]), creado por Davis en 1989. Los resultados obtenidos reflejan un elevado grado de aceptación de la tecnología de realidad aumentada por parte de los estudiantes participantes para conocer la distribución electrónica de los elementos de la tabla periódica. Asimismo, los estudiantes consideran que su uso es útil y muy divertido. En síntesis, la tecnología de realidad aumentada potencia la comprensión de conceptos de Química, ayuda a dinamizar las clases y facilita la enseñanza de temas abstractos a través del disfrute en la interacción con el objeto enriquecido en formato realidad aumentada

    Currently, a high percentage of the world’s population lives in urban areas, and this proportion will increase in the coming decades. In this context, indoor positioning systems (IPSs) have been a topic of great interest for researchers. On the other hand, Visible Light Communication (VLC) systems have advantages over RF technologies; for instance, they do not need satellite signals or the absence of electromagnetic interference to achieve positioning. Nowadays, in the context of Indoor Positioning (IPS), Visible Light Positioning (VLP) systems have become a strong alternative to RF-based systems, allowing the reduction in costs and time to market. This paper shows a low cost VLP solution for indoor systems. This includes multiple programmable beacons and a receiver which can be plugged to a smartphone running a specific app. The position information will be quickly and securely available through the interchange between the receiver and any configurable LED-beacon which is strategically disposed in an area. The implementation is simple, inexpensive, and no direct communication with any data server is required.This research was funded by INDRA-Adecco Foundation Chair on Accessible Technology, Comunidad de Madrid and the FSE/FEDER Program under grant SINFOTON2-CM (S2018/NMT-4326) and the UNIVERSIDAD CARLOS III DE MADRID under grant 2020/00038/001

    Sporadic cloud-based mobile augmentation on the top of a virtualization layer: a case study of collaborative downloads in VANETs

    Get PDF
    Current approaches to Cloud-based Mobile Augmentation (CMA) leverage (cloud-based) resources to meet the requirements of rich mobile applications, so that a terminal (the so-called application node or AppN) can borrow resources lent by a set of collaborator nodes (CNs). In the most sophisticated approaches proposed for vehicular scenarios, the collaborators are nearby vehicles that must remain together near the application node because the augmentation service is interrupted when they move apart. This leads to disruption in the execution of the applications and consequently impoverishes the mobile users’ experience. This paper describes a CMA approach that is able to restore the augmentation service transparently when AppNs and CNs separate. The functioning is illustrated by a NaaS model where the AppNs access web contents that are collaboratively downloaded by a set of CNs, exploiting both roadside units and opportunistic networking. The performance of the resulting approach has been evaluated via simulations, achieving promising results in terms of number of downloads, average download times, and network overheadMinisterio de Educación y Ciencia | Ref.

    Background: The objective of this research was to evaluate the behavior of 3 risk indicators for peripheral arterial disease in patients under oral treatment with rivaroxaban 2.5 mg every 12 hours plus, acetylsalicylic acid 100 mg every 24 hours. It was hypothesized that the oral combination of rivaroxaban and acetylsalicylic acid presents a therapeutic advantage over other treatments.Methods: A prospective longitudinal and non-randomized study of a single center was performed. 59 patients with peripheral arterial disease were included and treated with acetylsalicylic acid + rivaroxaban. Peak systolic velocity, ankle-brachial index and C reactive protein index were evaluated.Results: Significant changes were found at month 1 and 3 of follow-up in maximum systolic velocity, ankle-arm index and C-reactive protein index. The baseline peak systolic velocity (PSV) in the anterior tibial artery had significant differences after one month of treatment (p=0.001) and after 3 months (p=0.001). The baseline PSV in the posterior tibial artery had significant differences compared to the values found at the month of treatment (p=0.001) and 3 months (p=0.001). In the ankle-brachial index a baseline median of 0.790 was found, one month after the treatment of 0.795 (p=0.147) and 3 months after 0.800 (p=0.019). The mean baseline C-reactive protein obtained was 73.142 mg/l, at one month 87.233 mg/l (p=0.001) and at 3 months at 79.009 mg/l (p=0.294) with a standard deviation of 67.18, 74.78 and 69.69 respectively.Conclusions: The combined use of acetylsalicylic acid and rivaroxaban allows a clinical improvement in patients with peripheral arterial disease

    Breast cancer is recognized worldwide as a major health problem among women due to its high incidence and high mortality and morbidity rates. Breast reconstruction is an approach of great value for those patients who underwent mastectomy, impacting their quality of life and psychological stress. The deep inferior epigastric artery perforator (DIEP) flap was described as the preferred graft for breast reconstruction with an autologous flap by surgeons because it represented a decrease in complications for the time and obtained better results. DIEP flap reconstruction requires microsurgical skills as well as continuous monitoring of the patient to identify and resolve possible associated complications.

    Intestinal adhesions are bands of fibrous tissue created by the intimate contact of two injured surface tissues; these appear in 93% of the patient undergoing intra-abdominal or gastrointestinal surgery. The comorbidities associated with the formation of adhesions have an impact on quality care offered to patients, leading to an increase in healthcare. Goals of this study was to perform a review that includes different therapeutic alternatives in basic and clinical research to prevent the formation of postoperative abdominal peritoneal adhesions. A bibliographic search was conducted in different databases including Pub med, Medline, Cochrane, science direct, from the years 2000 to 2018 using the keywords: gastrointestinal adhesions, small bowel obstruction, prophylaxis, treatment. Only experimental and clinical articles were selected. The development of peritoneal adhesions in most of the experimental studies occurred with cecal abrasion, studying the effect of biodegradable materials, drugs and gels such as mXG Hydrogel. Nanofiber membranes, agents created with recombinant technology such as periostin antisense oligonucleotide and aerosol applications such as polysaccharide 4DryField PH, are positioned to replace in the future the actual limited mechanical barriers application commonly used in abdominal surgery such as seprafilm and interceed. There are several anti-adhesion agents in experimental phase with different mechanism of action that could be used in the short term to prevent the formation of post-surgical intestinal adhesions. The inclusion of gastrointestinal surgeons in basic research is increasing and necessary with multidisciplinary collaboration. It is expected in short term the study and development of a greater number of materials to minimize tissue trauma and decrease the formation of post-surgical adhesions

    Background: The concept of angiosome explains the anatomical variations that exist between the vessels of different regions of the body and helps to understand the contributions of arterial blood supply to the skin and adjacent structures, dividing the human body into three-dimensional vascular blocks.Methods: This was an observational and descriptive study. In both lower extremities of 5 corpses with adequate tissue preservation in the operating room attached to the teaching area of the National Institute of Forensic Sciences in Mexico City. Angiosome study of the medial neurocutaneous flap of the second toe of both feet was performed.Results: The average, in centimeters, of the surface of the flaps was 1.57 cm x 2.47 cm, the average diameter of the inter-metatarsal digital artery was 1.1 millimeters and the average diameter of the veins draining the angiosome was 1.4 millimeters. The most constant anatomy was that of the nerve, which was present in all cases, with the digital nerve forming the neurosome of the flap.Conclusions: To obtain optimal results in microsurgery transfers, it is necessary to have a technique that is quick for harvesting the flap and with adequate systematization so as not to injure the neurovascular bundle, this is achieved through complete anatomical knowledge, without forgetting the main variants
