Desarrollo de un ambiente de aprendizaje para fortalecer las competencias básicas en matemáticas bajo el enfoque del diseño universal de aprendizaje

Resumen – La educación se enfrenta a nuevos retos día a día. A lo largo de la historia se han venido proponiendo diversos métodos o conceptos que apunta a solucionar dichos retos, uno de esto es el Diseño Universal del Aprendizaje, también conocido por sus siglas como DUA, el cual consiste en presentar contenidos de diferentes formas para garantizar que existan varios caminos en la obtención del conocimiento. En este documento se hizo una investigación en torno a distintas plataformas en las cuales se podría implementar el Diseño Universal del Aprendizaje con el fin de tener una base en la cual trabajar y desarrollar lo que se buscaba, pero al final se decidió hacer una propia dado a las necesidades, y finalmente se creo un prototipo destinado a apoyar a los profesores en sus clases, para poder ofrecer nuevas herramientas que se adapten a un grupo heterogéneo de alumnos y de esta manera poder ofrecer un instrumento que sea de gran ayuda en el aula de clases, tanto para estudiantes y para profesores.Abstract - Education faces new challenges every day. Throughout history, several methods or concepts have been proposed aiming to solve these challenges, one of this is the Universal Design of Learning, also known by its acronym as UDL, which consists of presenting content in different ways to guarantee that there are several ways to obtain knowledge. In this document, an investigation was carried out around different platforms in which the Universal Design of Learning could be implemented in order to have a base on which to work and to develop in order to keep of the requirements of the project, but in the end it was decided not to use a market solution, instead create one that fits to the needs of the Universal Design of Learning, and finally a prototype was created to support teachers in their classes, to be able to offer new tools that adapt to a heterogeneous group of students and in this way to be able to offer an instrument that is of great help in the classroom, both for students and teachers

The validity and responsiveness of three quality of life measures in the assessment of psoriasis patients: results of a phase II study

BACKGROUND: Patient-reported outcome (PROs) measures are being used more frequently in investigational studies of treatments for moderate to severe plaque psoriasis. The objective of this study was to examine the relationships among the Dermatology Life Quality Index (DLQI), the Short Form 36 (SF-36), and the EuroQOL 5D (EQ-5D) and to assess their validity, responsiveness, and estimates of minimum important differences. METHODS: A Phase II, randomized, double-blind, parallel group, placebo-controlled, multi-center clinical trial assessed the clinical efficacy and safety of two doses of subcutaneously administered adalimumab vs. placebo for 12 weeks in the treatment of 147 patients with moderate to severe plaque psoriasis. This study provided the opportunity to evaluate the validity and responsiveness to change in clinical status of PROs instruments. Patients completed the DLQI, SF-36, and EQ-5D questionnaires at baseline and at 12 weeks. Blinded investigators assessed the Psoriasis Area and Severity Index (PASI) scores and the Physician's Global Assessment (PGA) scores of enrolled patients. The responsiveness of the measures to changes in the clinical endpoints from baseline to Week 12 was assessed. Estimates of minimum important differences (MID) were derived. All analyses were performed with blinded data; findings and conclusions were not biased based on treatment condition. RESULTS: The dermatology-specific DLQI was highly correlated to clinical endpoints at baseline and at Week 12, and was the most responsive PRO to changes in endpoints. Compared with the SF-36, the EQ-5D index score and VAS scores were generally more highly correlated with clinical endpoints, but displayed about the same degree of responsiveness. The most responsive SF-36 scales were the Bodily Pain and Social Functioning scales. Estimates of the MID for the DLQI ranged from 2.3–5.7 and for the SF-36 Physical Component Summary (PCS) score ranged from 2.5–3.9. CONCLUSION: This study provides support for the continued use of the DLQI and SF-36 PCS in the assessment of treatments for psoriasis. On the basis of the results from this trial, the EQ-5D should be considered as a general PRO measure in future clinical trials of patients with moderate to severe plaque psoriasis

Robust Spiking Attractor Networks with a Hard Winner-Take-All Neuron Circuit

Attractor networks are widely understood to be a re-occurring primitive that underlies cognitive function. Stabilising activity in spiking attractor networks however remains a difficult task, especially when implemented in analog integrated circuits (aIC). We introduce here a novel circuit implementation of a hard Winner-Take-All (hWTA) mechanism, in which competing neurons' refractory circuits are coupled together, and thus their spiking is forced to be mutually exclusive. We demonstrate stable persistent-firing attractor dynamics in a small on-chip network consisting of hWTA-connected neurons and excitatory recurrent synapses. Its utility within larger networks is demonstrated in simulation, and shown to support overlapping attractors and be robust to synaptic weight mismatch. The realised hWTA mechanism is thus useful for stabilising activity in spiking networks composed of unreliable components, without the need for careful parameter tuning

Diseño de la planeación del talento humano en la empresa Abyfragancias de la ciudad de Pereira Risaralda

El presente proyecto de grado tiene como finalidad diseñar la planificación del talento humano en la empresa de fragancias Abyfragancias de Pereira para el año 2022, a partir de un análisis aplicando en dicha compañía donde se identificaron las condiciones del talento humano actualmente en la empresa, teniendo en cuenta la importancia y papel protagónico que el ser humano tiene en las compañías para lograr las metas proyectadas. De esta manera, lo que se busca al planificar el área del talento humano, es identificar la insuficiencia real de la compañía frente al hecho de efectuar y/o reformar el área de gestión de la planificación del talento humano, a fin de identificar los requerimientos laborales, puesto que este factor conlleva claramente a la producción, a la mejora continua y al rendimiento de la organización. La descripción de la compañía producto de estudio, igualmente que el marco teórico hacen preferencia a algunos conceptos asociados a la tara y a la planificación del talento humano, la selección, evaluación, capacitaciones, compensaciones e incentivos al trabajador, encaminados siempre a que la compañía nos brinde un resultado positivo; donde sobresale la importancia no solo de contar con área de gestión de talento humano sino también de su planificación de tal manera que las personas estén de acuerdo con las exigencias con cada departamento de la compañía. Así mismo, se entregan conceptos generales para la planificación del talento humano en la empresa Abyfragancias, donde se atienden las necesidades tanto de la empresa de los colaboradores, poniendo en práctica modelo de gestión y desarrollo de los recursos humanos para así mismo obtener lograr alcanzar las metas proyectadas además que los colaboradores se sientan cómodos y una buena satisfacción laboral.The purpose of this degree project is to design the planning of human talent in the fragrance company Abyfragancias de Pereira for the year 2022, based on an analysis applied in the company where the conditions of human talent currently in the company were identified, taking into account the importance and leading role that the human being has in the companies to achieve the projected goals. In this way, what is sought when planning the area of human talent, is to identify the real insufficiency of the company in the fact of carrying out and/or reforming the management area of human talent planning, in order to identify the labor requirements, since this factor clearly leads to production, continuous improvement and performance of the organization. The description of the company product of study, as well as the theoretical framework give preference to some concepts associated with the tare and the planning of human talent, selection, evaluation, training, compensation and incentives to the worker, always aimed at the company to provide a positive result, which highlights the importance of not only having an area of human talent management but also its planning so that people are in accordance with the requirements with each department of the company. Likewise, general concepts for the planning of human talent in the company Abyfragancias are delivered, where the needs of both the company and the collaborators are attended, putting into practice the model of management and development of human resources in order to achieve the projected goals as well as that the collaborators feel comfortable and a good job satisfaction
