    Managing protected areas implies dealing with complex social-ecological systems where multiple dimensions (social, institutional, economic and ecological) interact over time for the delivery of ecosystem services. Uni-dimensional and top-down management approaches have been unable to capture this complexity. Instead, new integrated approaches that acknowledge the diversity of social actors in the decision making process are required. In this paper we put forward a novel participatory assessment approach which integrates multiple methodologies to reflect different value articulating institutions in the case of a Natura 2000 network site in the Basque Country. It integrates within a social multi-criteria evaluation framework, both the economic values of ecosystem services through a choice experiment model and ecological values by means of a spatial bio-geographic assessment. By capturing confronting social and institutional conflicts in protected areas the participatory integrated assessment approach presented here can help decision makers for better planning and managing Natura 2000 sites.Funding provided by IHOBE (Basque Environmental Agency) through the research project coded as OTRI 2008.0101 (UPV/EHU)

    This article shows a phase of a project whose main objective is the definition of a frame of reference for anapplication methodology of the Enterprise Actor Model - MADE, using as a similar basis the methodology for MultiagentSystems INGENIAS. MADE consists of entities whose relationships must be represented graphically, in such a waythat facilitates the design and implementation of software.The graphic representations required can be done with an existing graphic language through the definition of models.Five models represented in UML language class diagrams were defined: ADE Model, Task and Objective Model, InteractionModel, Environment Model and Organization Model. These models are a complete and robust representation of thesystem, which facilitates later software implementationEste artículo muestra una fase de un proyecto cuyo objetivo principal, es la definición de un marco dereferencia para una metodología de aplicación del Modelo Actor de Empresa- MADE, usando como base análoga lametodología para sistemas multiagentes INGENIAS. MADE consta de unas entidades cuyas relaciones deben poderrepresentarse gráficamente, de tal modo, que facilite el diseño e implementación software.Las representaciones gráficas requeridas, se pueden realizar con un lenguaje gráfico ya existente a través de la definición de modelos. Se definieron cinco modelos representados en diagramas de clase del lenguaje UML: Modelo de ADE, Modelo de tareas y objetivos, Modelo de interacción, Modelo de entorno y Modelo de Organización. Estos modelos son una representación completa y robusta del sistema, lo que facilita su posterior implementación software

    El presente trabajo tiene como finalidad describir la implementación de un sistema IPTV con protocolo Multicast, basados en un escenario planteado de una entidad educativa a nivel nacional, cuya sede principal se encuentra en la ciudad de Bogotá, está a su vez esta interconectada con unas subsedes en las ciudades de Medellín y Barranquilla, las cuales requiere de un sistema avanzado de datos que soporte una infraestructura de red de nueva generación tipo NGN. Se hace mención de cada uno de los pasos, requerimientos, comandos y conceptos involucrados para el desarrollo y configuración del servicio IPTV sobre una red MPLS; de igual manera, se describen los pasos para definir un plan QoS con los respectivos anchos de banda correspondientes, que permitan su aplicación, apoyados en máquinas virtuales que permiten la simulación y verificación del funcionamiento correcto del sistema en cada una de las sedes en tiempo real, garantizando la viabilidad de la implementación del sistema IPTV. Palabras clave: Direccionamiento IP, Redes LAN, WAN, GNS3, protocolo OSPF, Multicast, QoS, IPTV, trafico, ancho de banda, RTP, (S, G), (*, G).The purpose of this paper is to describe the implementation of an IPTV system with Multicast protocol, based on a scenario of an educational entity at the national level, whose main office is located in the city of Bogotá, Colombia. At the same time, it is interconnected with sub-offices in the cities of Medellín and Barranquilla which require an advanced data system that supports a new generation network infrastructure type NGN. Mention is made of each one of the steps, requirements, commands, and concepts involved in the development and configuration of the IPTV service over an MPLS network. In the same way, the steps are described to define a QoS plan with the respective corresponding bandwidths that will allow its application, supported by virtual machines that allow the simulation and verification of the correct operation of the system in each of the venues in real-time, guaranteeing the viability of the implementation of the IPTV system.

    Background: Management of health services implies challenges that must be addressed by skillful managers, flexible and capable of adapting to them. However, the skills required by health service managers are not clear. Objective: Identify managerial skills in the health sector and propose a tool that allows them to be evaluated in a standardized. Methods: Review of the topic of managerial skills in the health sector of studies available in Scielo, ScienceDirect and PubMed between 2011-2021. Manuscripts in English or Spanish were included, with quality according to critical evaluation criteria of the JBI for qualitative studies and that represented the most ponderable tendencies in the subject. A narrative synthesis was performed using Popay's four-item process and relevant details were extracted through standardized abstractions that included the main findings and observations. Finally, a tool with the potential to identify them was designed. Results: Thirteen manuscripts that met the inclusion criteria were analyzed. The managerial functions were defined and characterized according to the managerial profile in health applied to the Provider Institutions of Health Services in Colombia. Four fundamental managerial skills typical of the health sector were identified, which constitute independent variables; With this, a tool with the potential to identify them was designed. Conclusions: To manage health, skills in decision-making, leadership, communication skills, and time management are fundamentally required. The proposed tool has the potential to identify them, but future research must validate them.Antecedentes: La gestión de los servicios de salud entraña retos que deben ser abordados por gerentes hábiles, flexibles y capaces de adaptarse a ellos.

    Senescent cells occur in adults with cirrhotic livers independent of the etiology. Aim: Investigate the presence rate of cellular senescence and expression of cell cycle check points in livers from children with end stage disease. staining occurred in the areas of ductular transformation and in the interlobular bile ducts.Cellular senescence in livers of children with end stage disease is associated with damage rather than corresponding to an age dependent phenomenon. Further studies are needed to support the hypothesis that these senescence markers correlate with disease progression

    Masses, radii, and orbits of small Kepler planets : The transition from gaseous to rocky planets

    We report on the masses, sizes, and orbits of the planets orbiting 22 Kepler stars. There are 49 planet candidates around these stars, including 42 detected through transits and 7 revealed by precise Doppler measurements of the host stars. Based on an analysis of the Kepler brightness measurements, along with high-resolution imaging and spectroscopy, Doppler spectroscopy, and (for 11 stars) asteroseismology, we establish low false-positive probabilities (FPPs) for all of the transiting planets (41 of 42 have an FPP under 1%), and we constrain their sizes and masses. Most of the transiting planets are smaller than three times the size of Earth. For 16 planets, the Doppler signal was securely detected, providing a direct measurement of the planet's mass. For the other 26 planets we provide either marginal mass measurements or upper limits to their masses and densities; in many cases we can rule out a rocky composition. We identify six planets with densities above 5 g cm-3, suggesting a mostly rocky interior for them. Indeed, the only planets that are compatible with a purely rocky composition are smaller than 2 R ⊕. Larger planets evidently contain a larger fraction of low-density material (H, He, and H2O).Peer reviewedFinal Accepted Versio
