Nuevas alternativas a la Educación Física escolar: la educación en valores
La educación el valores es uno de los contenidos primordiales a desarrollar del currículo de Educación Primaria. En el siguiente trabajo pretendemos diseñar una propuesta didáctica en forma de unidad Didáctica que ayude a transmitir a los alumnos los valores necesarios para un desarrollo físico y cognitivo óptimo.
La herramienta mediante la cual habremos de cumplir este objetivo será la Educación Física escolar utilizando las estrategias y modelos de enseñanza óptima.Grado en Educación Primari
MasterFinger: Multi-finger Haptic Interface for Collaborative Environments
This paper introduces the Master Finger development and application, a multi-finger haptic interface for virtual object manipulation. This haptic device, with a modular interface, is specially designed to perform collaborative tasks. Each module is in charge of managing the haptic interaction with a finger. The mechanical structure of the module is based on a serial-parallel structure linked to the finger thimble by a gimble with its own controller. Cooperative applications based onMasterFinger-2 (MF2) are also described in this study. Results from these applications show that multifinger interface is a significant leap in haptic devices since precise object grasping and collaborative manipulation by using two hands are successfully performed
Queilitis granulomatosa de Miescher
La queilitis granulomatosa es un raro proceso de etiología desconocida que se considera una forma oligosintomática del síndrome de Melkersson-Rosenthal. En este artículo presentamos un caso y hacemos una revisión de los procesos granulomatosos en la región oral, los procesos que cursan con hinchazón labial y del tratamiento de la queilitis granulomatosa
Efficient Transport Protocol for Networked Haptics Applications
The performance of haptic application is highly sensitive to communication delays and losses of data. It implies several constraints in developing networked haptic applications. This paper describes a new internet protocol called Efficient Transport Protocol (ETP), which aims at developing distributed interactive applications. TCP and UDP are transport protocols commonly used in any kind of networked communication, but they are not focused on real time application. This new protocol is focused on reducing roundtrip time (RTT) and inter packet gap (IPG). ETP is, therefore, optimized for interactive applications which are based on processes that are continuously exchanging data.ETP protocol is based on a state machine that decides the best strategies for optimizing RTT and IPG. Experiments have been carried out in order to compare this new protocol and UDP
Complicaciones orales de la quimioterapia antineoplásica
Las complicaciones orales debidas a la quimioterapia antineoplásica pueden disminuir de forma importante el éxito terapéutico, así como la calidad de vida y la supervivencia de los paciente. En el presente trabajo describimos las principales complicaciones (mucositis, xerostomía, infecciones y hemorragia), así como las medidas adecuadas para su prevención y tratamiento, haciendo referencia a las pautas que debe seguir el odontólogo para higienizar el medio oral, realizar un correcto manejo estomatológico de estos pacientes y prevenir secuelas como la caríes
Brachytherapy in lip cancer
Lip cancer is one of the most prevalent skin tumours of the head and neck. The characteristics of the tumour relate to their exophyitic growth in an area of easy visual acces which allows their diagnosis in early stages. As a result, there is a better prognosis with the present treatments. In early stages the treatment can be performed by surgery or by brachytherapy, and the results are similar on local control; nevertheless brachytherapy offers the best functional and esthetic results. We are reporting on a review of the literature in relation to indications, techniques and results of brachytherapy for lip cance
Amelogénesis imperfecta tipo IE. a propósito de una familia afectada
En este artículo se revisa el concepto de Amelogénesis imperfecta a propósito de una familia afectada de Amelogénesis imperfecta tipo lE, según la clasificación de WITKOP. En primer lugar se hace un breve repaso de la entidad y de las complejas clasificaciones que sobre ella se han realizado, para pasar posteriormente a detallar la clínica, etiopatogenia y modo de transmisión del subtipo lE (IIa según la clasificación tradicional). Después se detalla el caso clínico de la familia que nos ocupa y finalmente se comentan las posibilidades terapéuticas, así como la importancia de la prevención en este tipo de pacientes
Efficient Transport Protocol for Networked
The performance of haptic application is highly sensitive to
communication delays and losses of data. It implies several constraints
in developing networked haptic applications. This paper describes a new
internet protocol called Efficient Transport Protocol (ETP), which aims
at developing distributed interactive applications. TCP and UDP are
transport protocols commonly used in any kind of networked communication,
but they are not focused on real time application. This new
protocol is focused on reducing roundtrip time (RTT) and interpacket
gap (IPG). ETP is, therefore, optimized for interactive applications
which are based on processes that are continuously exchanging data.

New control architecturebased on PXI for a 3-finger haptic device applied to virtual manipulation
To perform advanced manipulation of remote environments such as grasping, more than one finger is required implying higher requirements for the control architecture. This paper presents the design and control of a modular 3-finger haptic device that can be used to interact with virtual scenarios or to teleoperate dexterous remote hands. In a modular haptic device, each module allows the interaction with a scenario by using a single finger; hence, multi-finger interaction can be achieved by adding more modules. Control requirements for a multifinger haptic device are analyzed and new hardware/software architecture for these kinds of devices is proposed. The software architecture described in this paper is distributed and the different modules communicate to allow the remote manipulation. Moreover, an application in which this haptic device is used to interact with a virtual scenario is shown
Design and evaluation of an educational platform for implementing and testing bilateral control algorithms
This paper describes the design and evaluation of a
new platform created in order to improve the learning experience of bilateral control algorithms in teleoperation. This experimental platform, developed at Universidad Politécnica de Madrid, is used by the students of the Master on Automation and Robotics in the practices of the subject called “Telerobotics and Teleoperation”. The main objective is to easily implement different control architectures in the developed platform and evaluate them under different conditions to better understand the main advantages and drawbacks of each control scheme. So, the student’s tasks are focused on adjusting the control parameters of the predefined controllers and designing new ones to analyze the changes in the behavior of the whole system. A description of the subject, main topics and the platform constructed are
detailed in the paper. Furthermore, the methodology followed in the practices and the bilateral control algorithms are presented. Finally, the results obtained in the experiments with students are also shown
