Evaluación del Proceso de Gestión del Conocimiento de la RED GESCON,Matagalpa, periodo 2014

La presente investigación tiene como objetivo la evaluación del proceso de gestión del conocimiento de la RED GESCON, Matagalpa, periodo 2014. El trabajo se estructuró basado en los objetivos específicos que fueron establecidos, de los cuales proceden las variables de estudio que han sido plasmadas en el marco teórico y que avalan la veracidad y cientificidad de la investigación. De igual manera se elaboró un diseño metodológico que guió la metodología de investigación aplicada,esta comprende el enfoque de investigación,población y muestra y las técnicas e instrumentos para la recopilación de la información. Se elaboraron instrumentos para recopilar información, estos basados en el marco teórico desarrollado. Los instrumentos consistieron en una guía de entrevista aplicada a miembros del comité directivo de la red GESCON, una encuesta realizada de manera electrónica a miembros de la red y por último una tabla de análisis comparativo de características para seleccionar la alternativa informática propuesta, esto basado en el juicio de experto de dos docentes del área de informática. Los resultados de esta investigación demuestran que el proceso de gestión del conocimiento que la red lleva a cabo no es del todo eficaz según sus objetivos, al mismo tiempo, se encontraron puntos favorables que apoyan el mismo. No obstante la principal dificultad encontrada es que no se tiene una herramienta o protocolo definido de comunicación. De esto se derivan otros problemas como la dificultad en la consulta y obtención de información, comunicación limitada entre los miembros, entre otras, que en menor medida dificultan la gestión del conocimiento. Para estas problemáticas se propone una plataforma web que permita la interacción entre sus miembros manteniéndolos así comunicados y al tanto del accionar de la red

El presente estudio, tuvo por objetivo determinar el escore de lesiones intestinales macroscópicas de coccidias en pollos de engorde desafiados con cepas de campo locales de E. acervulina, E. maxima y E. tenella y suplementados con un programa anticoccidial (Salinomicina / Nicarbazina). El estudio se realizó en el galpón experimental del Laboratorio de Patología Aviar de la Facultad de Medicina Veterinaria de la Universidad Nacional Mayor de San Marcos; donde se utilizaron 600 pollos de engorde de la línea Cobb Vantress 500. El diseño comprendió 4 tratamientos: T1 (n=150), T2 (n=150), T3 (n=150) y T4 (n=150) con 6 repeticiones por tratamiento. T3 y T4 recibieron diferentes dosis del programa Salinomicina / Nicarbazina, 40 o 50 ppm de cada principio activo respectivamente, y fueron desafiados a los 14 días de edad, vía oral, con 1 mL de un inóculo con ooquistes de Eimerias colectadas de campo. Se registró mortalidad, signos clínicos y lesiones intestinales compatibles con coccidias desde los 14 a 28 días de edad. Al 7° día post desafío se determinó el escore de lesiones macroscópicas para coccidias utilizando la escala de + 0 a + 4 descrita en 1970 por Johnson y Reid. Se confirmó la presencia de especies de Eimeria mediante el raspado de la mucosa intestinal. En pollos de engorde, frente a un desafío con especies patógenas locales de Eimerias, el tratamiento anticoccidial demostró una significativa reducción de la mortalidad y signos clínicos por coccidiosis, y una significativa reducción del escore de lesiones intestinales macroscópicas de Eimeria acervulina y Eimeria maxima (p<0.05), mas no de Eimeria tenella.

A tensor optimization algorithm for Bézier Shape Deformation

In this paper we propose a tensor based description of the Bézier Shape Deformation (BSD) algorithm, denoted as T-BSD. The BSD algorithm is a well-known technique, based on the deformation of a Bézier curve through a field of vectors. A critical point in the use of real-time applications is the cost in computational time. Recently, the use of tensors in numerical methods has been increasing because they drastically reduce computational costs. Our formulation based in tensors T-BSD provides an efficient reformulation of the BSD algorithm. More precisely, the evolution of the execution time with respect to the number of curves of the BSD algorithm is an exponentially increasing curve. As the numerical experiments show, the T-BSD algorithm transforms this evolution into a linear one. This fact allows to compute the deformation of a Bézier with a much lower computational cost

Numerical strategies for the Galerkin–proper generalized decomposition method

The Proper Generalized Decomposition or, for short, PGD is a tensor decomposition based technique to solve PDE problems. It reduces calculation and storage cost drastically and presents some similarities with the Proper Orthogonal Decomposition, for short POD. In this work, we propose an efficient implementation to improve the convergence of the PGD, toward the numerical solution of a discretized PDE problem, when the associated matrix is Laplacian-like.The first author was partially supported by PRCEU-UCH 30/10 by Universidad CEU Cardenal Herrer

Aportaciones al estudio arqueológico del mudéjar en la Alpujarra: las iglesias de planta de cajón

This study approaches the standing remains of several Mudejar churches in the Alpujarra region. By means of the archaeological analysis of its walls, the revision of those related written sources and the study of its urban and territorial context, the hall-like plan churches are characterized as a singular typology of this region. This work has made possible as well to improve the knowledge of the parish introduction in the rural area of the Nasrid kingdom in Granada in the Christian period and of those buildings in use during that period in the region.En este artículo se aborda el estudio de los restos emergentes de varias iglesias mudéjares en la comarca de la Alpujarra.

Service-Oriented Device Integration for Ubiquitous Ambient Assisted Living Environments

As a result of the increment of population in countries of Europe, a lot of efforts from European Authorities are coming from. In our research we want to bring forward a suite of developments related to build a ubiquitous AAL (Ambient Assisted Living) environment. We consider that recent approaches are based on ad-hoc technologies so its application is in this context isolated just in one domain of application. Our approach addresses to a reliable services platform for heterogeneous devices integration. On this basis we want to consider as well, the underlying benefits that a Service-oriented platform is giving to us in our Ambient Assisted Living Applications.Ministerio de Educación y Ciencia TSI2006-13390-C02-02Junta de Andalucía TIC-2141Ministerio de Industria, Turismo y Comercio TSI-020400-2008-11

Decent Work as a Necessary Condition for Sustainable Well-Being. A Tale of Pi(i)gs and Farmers

This article analyzes with a holistic and systematic approach the state of working conditions in the European labor market after the crisis, as well as their effects on worker well-being. For this, a distinction will be made between the southern countries most affected, namely Portugal, Italy, Ireland, Greece, and Spain (Piigs), and the northern countries that are, a priori, less damaged by the crisis (Farmers). The samples integrate 7867 workers from the five Piigs countries (36.2%) and 13,894 from the 10 Farmers countries (63.8%). The results have broadly confirmed the research purposes and they established that ensuring well-being is the key to sustainability, growth, and success for workers, groups, and organizations

On the Existence of a Progressive Variational Vademecum based on the Proper Generalized Decomposition for a Class of Elliptic Parameterized Problems

In this study, we present the mathematical analysis needed to explain the convergence of a progressive variational vademecum based on the proper generalized decomposition (PGD). The PGD is a novel technique that was developed recently for solving problems with high dimensions, and it also provides new approaches for obtaining the solutions of elliptic and parabolic problems via the abstract separation of variables method. This new scenario requires a mathematical framework in order to justify its application to the solution of numerical problems and the PGD can help in the change to this paradigm. The main aim of this study is to provide a mathematical environment for defining the notion of progressive variational vademecum. We prove the convergence of this iterative procedure and we also provide the first order optimality conditions in order to construct the numerical approximations of the parameterized solutions. In particular, we illustrate this methodology based on a robot path planning problem. This is one of the common tasks when designing the trajectory or path of a mobile robot. The construction of a progressive variational vademecum provides a novel methodology for computing all the possible paths from any start and goal positions derived from a harmonic potential field in a predefined map

An autonomic framework for enhancing the quality of data grid services

Data grid services have been used to deal with the increasing needs of applications in terms of data volume and throughput. The large scale, heterogeneity and dynamism of grid environments often make management and tuning of these data services very complex. Furthermore, current high-performance I/O approaches are characterized by their high complexity and specific features that usually require specialized administrator skills. Autonomic computing can help manage this complexity. The present paper describes an autonomic subsystem intended to provide self-management features aimed at efficiently reducing the I/O problem in a grid environment, thereby enhancing the quality of service (QoS) of data access and storage services in the grid. Our proposal takes into account that data produced in an I/O system is not usually immediately required. Therefore, performance improvements are related not only to current but also to any future I/O access, as the actual data access usually occurs later on. Nevertheless, the exact time of the next I/O operations is unknown. Thus, our approach proposes a long-term prediction designed to forecast the future workload of grid components. This enables the autonomic subsystem to determine the optimal data placement to improve both current and future I/O operations
