The future obligations of "project manager" as construction integral director (DIPE) in the law of buildings construction in spain (LOE)

In the year 1999 approves the Law of Construction Building (LOE, in Spanish) to regulate a sector such as construction, which contained some shortcomings from the legal point of view. Currently, the LOE has been in force 12 years, changing the spanish world of the construction, due to influenced by internationalization. Within the LOE, there regulating the different actors involved in the construction building, as the Projects design, the Director of Construction, the developer, The builder, Director of execution of the construction (actor only in Spain, similar as construcion engineer and abroad in), control entities and the users, but lacks figure Project manager will assume the delegation of the promoter helping and you organize, direct and management the process. This figure assumes that the market and contracts are not legally regulated in Spain, then should define and establish its regulation in the LOE. (Spain Construction Law) The translation in spanish of the words "Project Manager is owed to Professor Rafael de Heredia in his book Integrated Project Management, as agent acting on behalf of the organization and promoter assuming control of the project, ie Integraded Project Management . Already exist in Spain, AEDIP (Spanish Association Integrated of Project Construction management) which comprises the major companies in “Project Management” in Spain, and MeDIP (Master in Integrated Construction Project) the largest and most advanced studies at the Polytechnic University of Madrid, in "Construction Project Management" they teach which is also in Argentina. The Integrated Project ("Project Management") applied to the construction process is a methodological technique that helps to organize, control and manage the resources of the promoters in the building process. When resources are limited (which is usually most situations) to manage them efficiently becomes very important. Well, we find that in this situation, the resources are not only limited, but it is limited, so a comprehensive control and monitoring of them becomes not only important if not crucial. The alternative of starting from scratch with a team that specializes in developing these follow directly intervening to ensure that scarce resources are used in the best possible way requires the use of a specific methodology (Manual DIP, Matrix Foreign EDR breakdown structure EDP Project, Risk Management and Control, Design Management, et ..), that is the methodology used by "Projects managers" to ensure that the initial objectives of the promoters or investors are met and all actors in process, from design to construction company have the mind aim of the project will do, trying to get their interests do not prevail over the interests of the project. Among the agents listed in the building process, "Project Management" or DIPE (Director Comprehensive building process, a proposed name for possible incorporation into the LOE, ) currently not listed as such in the LOE (Act on Construction Planning ), one of the agents that exist within the building process is not regulated from the legal point of view, no obligations, ie, as is required by law to have a project, a builder, a construction management, etc. DIPE only one who wants to hire you as have been advanced knowledge of their services by the clients they have been hiring these agents, there being no legal obligation as mentioned above, then the market is dictating its ruling on this new figure, as if it were necessary, he was not hired and eventually disappeared from the building process. As the aim of this article is regular the process and implement the name of DIPE in the Spanish Law of buildings construction (LOE)

Selectivity of diacylhydrazine insecticides to the predatory bug Orius laevigatus: In vivo and modeling/docking experiments

BACKGROUND: Knowledge of pesticide selectivity to natural enemies is necessary for a successful implementation of biological and chemical control methods in integrated pest management (IPM) programs. Diacylhydrazine (DAH)-based ecdysone agonists also known as molting-accelerating compounds (MACs) are considered a selective group of insecticides, and their compatibility with predatory Heteroptera, which are used as biological control agents, is known. However, their molecular mode of action has not been explored in beneficial insects such as Orius laevigatus (Fieber) (Hemiptera: Anthocoridae). RESULTS: In this project in vivo toxicity assays demonstrated that the DAH-based RH-5849, tebufenozide and methoxyfenozide have no toxic effect against O. laevigatus. The ligand-binding domain (LBD) of the ecdysone receptor (EcR) of O. laevigatus was sequenced and a homology protein model was constructed which confirmed a cavity structure with 12 ?-helixes, harboring the natural insect molting hormone 20-hydroxyecdysone. However, docking studies showed that a steric clash occurred for the DAH-based insecticides due to a restricted extent of the ligand-binding cavity of the EcR of O. laevigatus. CONCLUSIONS: The insect toxicity assays demonstrated that MACs are selective for O. laevigatus. The modeling/docking experiments are indications that these pesticides do not bind with the LBD-EcR of O. laevigatus and support that they show no biological effects in the predatory bug. These data help in explaining the compatible use of MACs together with predatory bugs in IPM programs. Keywords: Orius laevigatus, selectivity, diacylhydrazine insecticides, ecdysone receptor, homology modelling, docking studies.

Estudio de la aplicabilidad de las aproximaciones uniformes al análisis de series históricas : aplicación al caso de los precios del cobre

El objetivo de este proyecto de investigación es comparar dos técnicas matemáticas de aproximación polinómica, las aproximaciones según el criterio de mínimos cuadrados y las aproximaciones uniformes (“minimax”). Se describen tanto el mercado actual del cobre, con sus fluctuaciones a lo largo del tiempo, como los distintos modelos matemáticos y programas informáticos disponibles. Como herramienta informática se ha seleccionado Matlab®, cuya biblioteca matemática es muy amplia y de uso muy extendido y cuyo lenguaje de programación es suficientemente potente para desarrollar los programas que se necesiten. Se han obtenido diferentes polinomios de aproximación sobre una muestra (serie histórica) que recoge la variación del precio del cobre en los últimos años. Se ha analizado la serie histórica completa y dos tramos significativos de ella. Los resultados obtenidos incluyen valores de interés para otros proyectos. Abstract The aim of this research project is to compare two mathematical models for estimating polynomial approximation, the approximations according to the criterion of least squares approximations uniform (“Minimax”). Describes both the copper current market, fluctuating over time as different computer programs and mathematical models available. As a modeling tool is selected main Matlab® which math library is the largest and most widely used programming language and which is powerful enough to allow you to develop programs that are needed. We have obtained different approximating polynomials, applying mathematical methods chosen, a sample (historical series) which indicates the fluctuation in copper prices in last years. We analyzed the complete historical series and two significant sections of it. The results include values that we consider relevant to other projects

Consultoría en el marco económico-financiero de la empresa

Muchas de las grandes iniciativas empresariales, se ven truncadas por falta de un adecuado análisis económico-financiero. Incluso, muchas grandes ideas no son implantadas correctamente en el primer intento por este motivo, y son otras personas las que consiguen posteriormente el éxito de esas brillantes ideas gracias a una correcta aproximación financiera. Las empresas necesitan definir sus objetivos, establecer las para lograrlos, identificar las personas responsables de su ejecución (sus roles y funciones) y elaborar un plan económico-financiero que recoja el estudio de inversiones necesarias, el análisis de costes, la previsión de ingresos, así como la estrategia financiera más adecuada para la captación de los fondos necesarios para llevar a cabo las acciones programadas. Una vez iniciado el proyecto empresarial, será imprescindible realizar un seguimiento y control de la evolución (integración), tomando las medidas que se estimen oportunas para mantener el rumbo adecuado durante todo el tiempo de actividad. En este trabajo, aplicaremos las metodologías y buenas prácticas de la gestión de proyectos, como marco estructurado que nos permita abordar las principales cuestiones económico-financieras a tener en cuenta a la hora de enfrentarnos a un proyecto empresarial, para contribuir, en la medida de lo posible, a que los emprendedores tengan en cuenta estas cuestiones, facilitando así el desarrollo de negocios, en un difícil entorno económico de crisis como el que actualmente estamos viviendo en España, y animando de esta manera a optar por la iniciativa emprendedora, tratando de minimizar el riesgo en base al contenido. ---ABSTRACT---Lack of adequate economic and financial analysis truncates many of the entrepreneurship and innovation programs. Because of that reason, many great ideas are not even correctly implemented on the first attempt, and the person who finds the proper financial approach, succeed. All the enterprises have to establish clear objectives, actions to accomplish those objectives, assign roles, responsibilities and executive functions to specific people. Elaborate funding plan that contains surveys on necessary investments, cost analysis, estimate the income, liquid assets and also financial strategy suitable for fundraising to finance programmed actions. Once the project has been executed it is essential to monitor and control the development and integration adopting measures accordingly to the needs. This thesis applies methodology and best practice of project management as structured framework for the principal economic and financial issues facing business project. It is necessary contribution to entrepreneurs understanding of business, therefore facilitates business development in such rough environment as Spain is at this moment, and at the same time encourages adopting entrepreneur’s solution as less risky one. This document aims to explore all the economic and financial issues from methodological point of view based on my own professional experience, resulting in helping to understand the importance that economy and finances have in developing adequate corporate strategy. Crisis has highlighted inadequate functionality of many companies. Most popular first symptom is lack of cash flow that deteriorates the company, and results in suspension of payments followed by closing. In other cases, difficulties appear due to poor financial management of committed resources; to be observed in lack of prevision and planning or incorrect basic functionality and operational matters on daily basis. What would be your advice to someone who have magnificent business idea however no knowledge on how to handle finances in order to succeed in initiating and executing the project? Despite of the fact that the central nucleus of this paper is at economics and finances area, all the other concepts and topics given during master will be revived; for example business strategy, consultants abilities, organization and standard processes, among others, are impregnated with knowledge of project management.

Evaluation of the competitiveness of agri-food sector in the región of the Alcarria Conquense(Spain)

The agrifood industry, like other sectors, faces the ongoing challenge of improving their competitiveness in order to strengthen its market presence and cater to the growing global population. This research measures the competitiveness of the agrifood industry in the region of La Alcarria Conquense (Spain), in the framework of the evaluation of programs in the territory that have aimed at improving and enhancing this sector. Through building the competitiveness profiles (Porter, 1990) and cluster analysis we have identified six competitive strategy patterns in food companies in the region. In addition, we have analyzed each of the areas of competitiveness and we can identify the strengths and weaknesses of the sector, and identify recommendations for increasing the responsiveness of the territory. Among the defining characteristics are the lack of association, the limitation on payment systems or virtual absence of training and innovation. However, programs to support the sector are highly valued and reverse in the long-term viability of these companies.

Resilence, rural development and suistainable management: a working with people model approach

Nowadays, it has become evident the need to seek sustainable development models that address challenges arising in a variety of contexts. The resilience concept appears connected to the ability of people to cope with adversities that inevitably arise due to context dynamics, at different spatial and temporal scales. This concept is related to the model known as Working With People (WWP), focused on rural development projects planning, management and evaluation, from the integration of three dimensions: technical-entrepreneurial, ethical-social and political-contextual. The research reported is part of the RETHINK European Project, whose overall aim is farm modernization and rural resilience. The resilience concept has been analyzed, in the scope of rural development projects management, and a relationship with the WWP model has been established. To this end, a thorough review of the scientific literature concerning this topic has been addressed, in order to develop the state of the art of the different concepts and models involved. A conceptual proposal for the integration of resilience in rural development projects sustainable management, through the three-dimensional WWP model is presented.

Communication Project for development: 25 years of experience in andean rural communities in Ecuador

IThis paper analyses communication for development from a new perspective: the project in its broader and most genuine sense, as an instrument for changing current reality. This is examined from both its theoretical and practical implementation side. Knowledge/action binomial as a two-way relationship is one of the basis of the project cycle. It allows for better knowing the reality that the project itself (what constitutes the action) is intended to improve. Besides that, this knowledge/action binomial also offers new knowledge that nourishes future actions (projects). From a project based communication perspective, the project nourishes the knowledge, which leads to a transformative action. Reflecting about the action is a new knowledge source whose adoption by the community is eased by the communication process. Radio Mensaje project among the indigenous Andean communities in Cayambe (Ecuador) was born and also developed within this approach, supporting the collaborative participation in project management. This leads to the development process which is described in this case study.

Best practices for school leaders: Implementation of a profesional competence model for school management in Chile

In Chile, during the last three decades there has been a strong decentralization process whose main objective has been to improve the management of schools through the transfer of responsibilities and resources of education and thus improve the outcome of learning, reducing equity gaps between schools and territories. This is how, there has been an evolution of school principals¿ professional profile from an administrative to a management approach, in which principals have become project managers of educational projects. From a competence model for school leaders, based on IPMA guidelines, the present article presents an analysis of best practices for school management, allowing to generate a link between competencies and school management, from the perspective of project management. Results showed that the different competence elements, have relative weights according to the different practice fields, and that this analysis can be considered as a strategic element in educational project planning and development.

Análisis del comportamiento de uniones metálicas viga-soporte mediante modelo de elementos finitos y comparación de resultados con el modelo de nudos y barras

Para el proyecto y cálculo de estructuras metálicas, fundamentalmente pórticos y celosías de cubierta, la herramienta más comúnmente utilizada son los programas informáticos de nudos y barras. En estos programas se define la geometría y sección de las barras, cuyas características mecánicas son perfectamente conocidas, y sobre las cuales obtenemos unos resultados de cálculo concretos en cuanto a estados tensionales y de deformación. Sin embargo el otro componente del modelo, los nudos, presenta mucha mayor complejidad a la hora de establecer sus propiedades mecánicas, fundamentalmente su rigidez al giro, así como de obtener unos resultados de estados tensionales y de deformación en los mismos. Esta “ignorancia” sobre el comportamiento real de los nudos, se salva generalmente asimilando a los nudos del modelo la condición de rígidos o articulados. Si bien los programas de cálculo ofrecen la posibilidad de introducir nudos con una rigidez intermedia (nudos semirrígidos), la rigidez de cada nudo dependerá de la geometría real de la unión, lo cual, dada la gran variedad de geometrías de uniones que en cualquier proyecto se nos presentan, hace prácticamente inviable introducir los coeficientes correspondientes a cada nudo en los modelos de nudos y barras. Tanto el Eurocódigo como el CTE, establecen que cada unión tendrá asociada una curva momento-rotación característica, que deberá ser determinada por los proyectistas mediante herramientas de cálculo o procedimientos experimentales. No obstante, este es un planteamiento difícil de llevar a cabo para cada proyecto. La consecuencia de esto es, que en la práctica, se realizan extensas comprobaciones y justificaciones de cálculo para las barras de las estructuras, dejando en manos de la práctica común la solución y puesta en obra de las uniones, quedando sin justificar ni comprobar la seguridad y el comportamiento real de estas. Otro aspecto que conlleva la falta de caracterización de las uniones, es que desconocemos como afecta el comportamiento real de éstas en los estados tensionales y de deformación de las barras que acometen a ellas, dudas que con frecuencia nos asaltan, no sólo en la fase de proyecto, sino también a la hora de resolver los problemas de ejecución que inevitablemente se nos presentan en el desarrollo de las obras. El cálculo mediante el método de los elementos finitos, es una herramienta que nos permite introducir la geometría real de perfiles y uniones, y nos permite por tanto abordar el comportamiento real de las uniones, y que está condicionado por su geometría. Por ejemplo, un caso típico es el de la unión de una viga a una placa o a un soporte soldando sólo el alma. Es habitual asimilar esta unión a una articulación. Sin embargo, el modelo por elementos finitos nos ofrece su comportamiento real, que es intermedio entre articulado y empotrado, ya que se transmite un momento y el giro es menor que el del apoyo simple. No obstante, la aplicación del modelo de elementos finitos, introduciendo la geometría de todos los elementos estructurales de un entramado metálico, tampoco resulta en general viable desde un punto de vista práctico, dado que requiere invertir mucho tiempo en comparación con el aumento de precisión que obtenemos respecto a los programas de nudos y barras, mucho más rápidos en la fase de modelización de la estructura. En esta tesis se ha abordado, mediante la modelización por elementos finitos, la resolución de una serie de casos tipo representativos de las uniones más comúnmente ejecutadas en obras de edificación, como son las uniones viga-pilar, estableciendo el comportamiento de estas uniones en función de las variables que comúnmente se presentan, y que son: •Ejecución de uniones viga-pilar soldando solo por el alma (unión por el alma), o bien soldando la viga al pilar por todo su perímetro (unión total). •Disposición o no de rigidizadores en los pilares •Uso de pilares de sección 2UPN en cajón o de tipo HEB, que son los tipos de soporte utilizados en casi el 100% de los casos en edificación. Para establecer la influencia de estas variables en el comportamiento de las uniones, y su repercusión en las vigas, se ha realizado un análisis comparativo entre las variables de resultado de los casos estudiados:•Estados tensionales en vigas y uniones. •Momentos en extremo de vigas •Giros totales y relativos en nudos. •Flechas. Otro de los aspectos que nos permite analizar la casuística planteada, es la valoración, desde un punto de vista de costos de ejecución, de la realización de uniones por todo el perímetro frente a las uniones por el alma, o de la disposición o no de rigidizadores en las uniones por todo el perímetro. Los resultados a este respecto, son estrictamente desde un punto de vista económico, sin perjuicio de que la seguridad o las preferencias de los proyectistas aconsejen una solución determinada. Finalmente, un tercer aspecto que nos ha permitido abordar el estudio planteado, es la comparación de resultados que se obtienen por el método de los elementos finitos, más próximos a la realidad, ya que se tiene en cuenta los giros relativos en las uniones, frente a los resultados obtenidos con programas de nudos y barras. De esta forma, podemos seguir usando el modelo de nudos y barras, más versátil y rápido, pero conociendo cuáles son sus limitaciones, y en qué aspectos y en qué medida, debemos ponderar sus resultados. En el último apartado de la tesis se apuntan una serie de temas sobre los que sería interesante profundizar en posteriores estudios, mediante modelos de elementos finitos, con el objeto de conocer mejor el comportamiento de las uniones estructurales metálicas, en aspectos que no se pueden abordar con los programas de nudos y barras. For the project and calculation of steel structures, mainly building frames and cover lattices, the tool more commonly used are the node and bars model computer programs. In these programs we define the geometry and section of the bars, whose mechanical characteristics are perfectly known, and from which we obtain the all calculation results of stresses and displacements. Nevertheless, the other component of the model, the nodes, are much more difficulty for establishing their mechanical properties, mainly the rotation fixity coefficients, as well as the stresses and displacements. This "ignorance" about the real performance of the nodes, is commonly saved by assimilating to them the condition of fixed or articulated. Though the calculation programs offer the possibility to introducing nodes with an intermediate fixity (half-fixed nodes), the fixity of every node will depend on the real connection’s geometry, which, given the great variety of connections geometries that in a project exist, makes practically unviable to introduce the coefficients corresponding to every node in the models of nodes and bars. Both Eurocode and the CTE, establish that every connection will have a typical moment-rotation associated curve, which will have to be determined for the designers by calculation tools or experimental procedures. Nevertheless, this one is an exposition difficult to carry out for each project. The consequence of this, is that in the practice, in projects are extensive checking and calculation reports about the bars of the structures, trusting in hands of the common practice the solution and execution of the connections, resulting without justification and verification their safety and their real behaviour. Another aspect that carries the lack of the connections characterization, is that we don´t know how affects the connections real behaviour in the stresses and displacements of the bars that attack them, doubts that often assault us, not only in the project phase, but also at the moment of solving the execution problems that inevitably happen in the development of the construction works. The calculation by finite element model is a tool that allows us to introduce the real profiles and connections geometry, and allows us to know about the real behaviour of the connections, which is determined by their geometry. Typical example is a beam-plate or beam-support connection welding only by the web. It is usual to assimilate this connection to an articulation or simple support. Nevertheless, the finite element model determines its real performance, which is between articulated and fixed, since a moment is transmitted and the relative rotation is less than the articulation’s rotation. Nevertheless, the application of the finite element model, introducing the geometry of all the structural elements of a metallic structure, does not also turn out to be viable from a practical point of view, provided that it needs to invest a lot of time in comparison with the precision increase that we obtain opposite the node and bars programs, which are much more faster in the structure modelling phase. In this thesis it has been approached, by finite element modelling, the resolution of a representative type cases of the connections commonly used in works of building, since are the beam-support connections, establishing the performance of these connections depending on the variables that commonly are present, which are: •Execution of beam-support connections welding only the web, or welding the beam to the support for the whole perimeter. •Disposition of stiffeners in the supports •Use 2UPN in box section or HEB section, which are the support types used in almost 100% building cases. To establish the influence of these variables in the connections performance, and the repercussion in the beams, a comparative analyse has been made with the resulting variables of the studied cases: •Stresses states in beams and connections. •Bending moments in beam ends. •Total and relative rotations in nodes. •Deflections in beams. Another aspect that the study allows us to analyze, is the valuation, from a costs point of view, of the execution of connections for the whole perimeter opposite to the web connections, or the execution of stiffeners. The results of this analyse, are strictly from an economic point of view, without prejudice that the safety or the preferences of the designers advise a certain solution. Finally, the third aspect that the study has allowed us to approach, is the comparison of the results that are obtained by the finite element model, nearer to the real behaviour, since the relative rotations in the connections are known, opposite to the results obtained with nodes and bars programs. So that, we can use the nodes and bars models, more versatile and quick, but knowing which are its limitations, and in which aspects and measures, we must weight the results. In the last part of the tesis, are relationated some of the topics on which it would be interesting to approach in later studies, with finite elements models, in order to know better the behaviour of the structural steel connections, in aspects that cannot be approached by the nodes and bars programs.

Modelado experimental de un sistema de e-Salud aplicado en cooperación al desarrollo

Los Objetivos de Desarrollo del Milenio comprometieron a los países con una nueva alianza mundial de alcanzar gradualmente una cobertura universal de los niveles mínimos de bienestar en los países en desarrollo (reducir la pobreza y el hambre y dar respuesta a problemas como la mala salud, las desigualdades de género, la falta de educación, el acceso a agua salubre y la degradación ambiental). Para dar continuidad a esta iniciativa, recientemente en septiembre de 2015, la ONU promulgó la declaración de los Objetivos de Desarrollo Sostenible. Los ODM sitúan la salud en el corazón del desarrollo y establecen un novedoso pacto mundial que vincula a los países desarrollados y los países en desarrollo por medio de obligaciones claras y recíprocas. En este sentido, diversos organismos de cooperación a través de sus programas de cooperación internacional, tratan de mejorar el acceso a la asistencia sanitaria, especialmente a la población vulnerable que vive en zonas rurales de países en desarrollo. Con el fin de ayudar a cumplir los ODM que apoyan los temas de salud en dicha población, estos organismos desarrollan proyectos que despliegan sistemas de e-salud. Las intervenciones se enfrentan a múltiples retos: condicionantes de los países en desarrollo, las necesidades y demandas de los sistemas sanitarios y la complejidad de implantar las TIC en entornos complejos y altamente dinámicos como son los países en desarrollo. Estos condicionantes ocasionan la mayoría de proyectos fallidos que terminan convirtiéndose en soluciones aisladas, que anteponen la tecnología a las necesidades de la población y no generan el impacto esperado en su desarrollo. En este contexto tuvo origen esta tesis doctoral, que persigue como objetivo analizar, planificar, diseñar, verificar y validar un marco arquitectónico de implantación de sistemas de e-salud en áreas rurales de países en desarrollo, que promueva el mejoramiento de la calidad de vida de la población vulnerable de estas regiones y la efectividad de las intervenciones de e-salud en el marco de proyectos de cooperación al desarrollo. Para lograrlo, tomé como punto de partida, diversas estrategias, modelos, metodologías de implantación de e-salud, modelos de gestión de proyectos propuestos por distintos organismos internacionales y propuse una instanciación de estos modelos a proyectos de implantación de sistemas de e-salud en países en desarrollo. Apliqué la metodología action research y los enfoques twin track, middle out y design thinking que me permitieron el refinamiento iterativo del modelo propuesto en la tesis doctoral mediante el trabajo de campo realizado en dos zonas rurales de países de Centroamérica: Jocotán (Guatemala) y San José de Cusmapa (Nicaragua). Como resultado obtuve un modelo experimental basado en cuatro componentes: un modelo de referencia tipo, un modelo conceptual de e-salud, los procesos de gestión y de implantación de sistemas de e-salud en países en desarrollo y una arquitectura de referencia. El modelo experimental resultante aporta herramientas importantes para el despliegue de sistemas de e-salud en países en desarrollo. Se ha propuesto un modelo de referencia que proporciona una visión holística del contexto del país en desarrollo donde se desarrollarán las intervenciones. Un modelo conceptual de e-salud que representa los principales conceptos involucrados en un sistema de e-salud. Los procesos ii- de gestión del proyecto y de implantación del sistema que proporcionan a los grupos de cooperación, herramientas para el análisis, diseño, desarrollo y despliegue de los sistemas de e-salud en áreas rurales de países en desarrollo. Y finalmente la arquitectura de referencia que sienta las bases para la aplicación de estos procesos a un contexto en particular. Las líneas futuras de trabajo sugieren extender el modelo a más casos de estudio que permitan su refinamiento y evaluar los futuros usos que pueden surgir de los sistemas de e-salud resultantes. ABSTRACT Millennium Development Goals (MDGs) committing the countries with a new global partnership to achieve universal coverage of minimum levels of well-being in Developing Countries (for addressing extreme poverty in its many dimensions-income poverty, hunger, disease, lack of adequate housing, and exclusion-while promoting gender equality, education, and environmental sustainability). From September 2015, these goals are replaces with Sustainable Development Goals (SDGs). The MDG place health at the heart of development and establish a novel global compact, linking developed and developing countries through clear, reciprocal obligations. Many public and private institutions promote international cooperation programs to support in achieving the MDGs. Some of these cooperation programs deal improving access to healthcare to poor people living in isolated areas from developing countries. In order to accomplish this goal organizations perform projects (interventions or cooperation projects) that deploy e-health systems in these zones. Nevertheless, this kind of projects face multiple challenges that dismiss the effectiveness of the projects results. In particular, cooperation teams face issues such as constraints in developing countries, lack of electrical and ICT infrastructure, scarce transport, extreme climate conditions, lack ICT capacity, lack of access to healthcare and inefficient delivery methods, etc. Hence, these issues increase the complexity of implementing e-health in developing countries and then causes the most projects fail. In other words, the solutions do not meet population needs and do not generate the expected impact on development. This context is the starting point of this doctoral thesis, which deals with analysing, planning, designing, testing and validating an architectural framework in order to implement e-health systems in rural areas from developing countries, promote development of the population in these regions, and thus improve the impact of interventions of development cooperation projects. To achieve this goal, I took as a starting point the strategies, models, e-health implementation methodologies and projects management models proposed by various international agencies. Then I proposed an instantiation of these models to manage the intervention and implement e-health systems in developing countries. I applied the action research methodology and the approaches twin track, middle out and design thinking which allowed me the iterative refinement of the model proposed in this doctoral thesis. The proposed framework was validated by running two cases studies in rural areas of Central America: Jocotán (Guatemala) and San José de Cusmapa (Nicaragua). As a result, I obtained an experimental model based on four components: a Type reference model, an e-health conceptual model, both process management and implementation e-health systems in developing countries and a reference architecture. The resulting experimental model provides important tools for the deployment of e-health systems in developing countries. The model become as reference model that provides a holistic view of the developing countries context where the interventions will be running. The conceptual model of e-health represents the main concepts involved into an e-health system. The project management and implementation processes of the iv- system provide to the cooperation teams with tools for analysing, designing, developing and deploying e-health systems in rural areas from developing countries. Finally, the reference architecture provides the basis for the implementation of these processes into a particular context. The future research suggest the extension the model to other cases studies in order to refine and evaluate the viability the model.
