In universities, in any type of faculty or research institute, it is possible to observe innumerable informatics applications: database management, organization of catalogues, expediting diagnoses and many other applications. Within this context, distance learning could facilitate the learning of various professions. Distance education is the process of teaching-learning and the professional has to be prepared to deal with the new tools that are made available, using them to his/her benefit, and consequently in his/her professional capacity, to guarantee greater productivity and interaction with the various spheres in the work field. Methods: The aim of this research is to develop a course on the use of the Dentistry software application EasyDental, using the teaching at a distance methodology by means of the Moodle platform. The proposed course was composed of 14 modules, in order to enable a progressive and a rational learning. Conclusion: It could be concluded that this platform allowed the preparation of the proposed distance course, in a practical and versatile manner, considering the resources and activities it has. However, to use this platform, one must have dominion of the basic concepts of informatics, and the tools of the Moodle platform.

Background The use of the knowledge produced by sciences to promote human health is the main goal of translational medicine. To make it feasible we need computational methods to handle the large amount of information that arises from bench to bedside and to deal with its heterogeneity. A computational challenge that must be faced is to promote the integration of clinical, socio-demographic and biological data. In this effort, ontologies play an essential role as a powerful artifact for knowledge representation. Chado is a modular ontology-oriented database model that gained popularity due to its robustness and flexibility as a generic platform to store biological data; however it lacks supporting representation of clinical and socio-demographic information. Results We have implemented an extension of Chado – the Clinical Module - to allow the representation of this kind of information. Our approach consists of a framework for data integration through the use of a common reference ontology. The design of this framework has four levels: data level, to store the data; semantic level, to integrate and standardize the data by the use of ontologies; application level, to manage clinical databases, ontologies and data integration process; and web interface level, to allow interaction between the user and the system. The clinical module was built based on the Entity-Attribute-Value (EAV) model. We also proposed a methodology to migrate data from legacy clinical databases to the integrative framework. A Chado instance was initialized using a relational database management system. The Clinical Module was implemented and the framework was loaded using data from a factual clinical research database. Clinical and demographic data as well as biomaterial data were obtained from patients with tumors of head and neck. We implemented the IPTrans tool that is a complete environment for data migration, which comprises: the construction of a model to describe the legacy clinical data, based on an ontology; the Extraction, Transformation and Load (ETL) process to extract the data from the source clinical database and load it in the Clinical Module of Chado; the development of a web tool and a Bridge Layer to adapt the web tool to Chado, as well as other applications. Conclusions Open-source computational solutions currently available for translational science does not have a model to represent biomolecular information and also are not integrated with the existing bioinformatics tools. On the other hand, existing genomic data models do not represent clinical patient data. A framework was developed to support translational research by integrating biomolecular information coming from different “omics” technologies with patient’s clinical and socio-demographic data. This framework should present some features: flexibility, compression and robustness. The experiments accomplished from a use case demonstrated that the proposed system meets requirements of flexibility and robustness, leading to the desired integration. The Clinical Module can be accessed in http://dcm.ffclrp.usp.br/caib/pg=iptrans webcite.

[ES]El objetivo de este Trabajo es el de actualizar un entorno de gestión de bases de datos existente a la versión 11.2 del software de bases de datos Oracle y a una plataforma hardware de última generación. Se migran con tiempo de parada cero varias bases de datos dispersas en distintos servidores a un entorno consolidado de dos nodos dispuestos en alta disponibilidad tipo "activo-activo" mediante Oracle RAC y respaldado por un entorno de contingencia totalmente independiente y sincronizado en tiempo real mediante Oracle GoldenGate. Se realiza un estudio del entorno actual y, realizando una estimación de crecimiento, se propone una configuración de hardware y software mínima para implementar con garantías de éxito los requerimientos del entorno de gestión de bases de datos a corto y medio plazo. Una vez adquirido el hardware, se lleva a cabo la instalación, actualización y configuración del Sistema Operativo y el acceso redundado de los servidores a la cabina de almacenamiento. Posteriormente se instala el software de clúster de Oracle, el software de la base de datos y se crea una instancia que albergará los esquemas requeridos de las bases de datos a consolidar. Seguidamente se migran los esquemas al entorno consolidado y se establece la replicación de éstos en tiempo real con la máquina de contingencia usando en ambos casos Oracle GoldenGate. Finalmente se crea y prueba un esquema de copias de seguridad que incluye copias lógicas y físicas de la propia base de datos y de archivos de configuración del clúster a partir de los cuales será posible restaurar el entorno completamente.

[ES] Un servicio de urgencias de una zona ofrece asistencia sanitaria y tiene como principal objetivo atender la patología urgente que acude al hospital y el nivel de compromiso que se asume consiste en diagnosticar, tratar y estabilizar, en la medida posible, dicha patología urgente. Otro objetivo es gestionar la demanda de atención urgente por parte del ciudadano a través de un sistema de selección prioritaria inicial (Triaje) que selecciona, prioriza, organiza y gestiona la demanda de atención. Para poder controlar y realizar el trabajo de la forma más eficaz se utilizan herramientas de gestión necesarias para el control de los pacientes, desde que se realiza su ingreso en el servicio de urgencias hasta el alta del mismo. Las aplicaciones desarrolladas son las siguientes: Gestión de Pacientes en Urgencias: Esta aplicación asignará un estado inicial al paciente y permitirá ir cambiando el estado del mismo usando el método del Triaje (valoración), el más difundido en la medicina de urgencias. Además, se podrán solicitar pruebas diagnósticas y la visualización de marcadores de analíticas para comprobar su evolución. Finalmente, se podrá desarrollar un informe de alta para el paciente. Informadores de Urgencias: La aplicación gestiona la localización física del paciente dentro del servicio de urgencias, permitiendo asimismo el cambio entre las distintas localizaciones y el control para la información a los familiares de los mismos, pudiendo almacenar los familiares y teléfonos de contactos para que estos puedan ser informados. El desarrollo se ha realizado utilizando el MVC (modelo - vista - controlador) que es patrón de arquitectura que separa los datos de una aplicación, la interfaz gráfica de usuario y la lógica de control de componentes. El software utilizado para el desarrollo de las aplicaciones es CACHÉ de Intersystems que permite la creación de una base de datos multidimensional. El modelo de objetos de Caché se basa en el estándar ODMG (Object Database Management Group, Grupo de gestión de bases de datos de objetos) y soporta muchas características avanzadas. CACHÉ dispone de Zen, una biblioteca completa de componentes de objetos preconstruidos y herramientas de desarrollo basadas en la tecnología CSP (Caché Server Pages) y de objetos de InterSystems. ZEN es especialmente apropiado para desarrollar una versión Web de las aplicaciones cliente/servidor creadas originalmente con herramientas como Visual Basic o PowerBuilder.

In recent years, learning analytics (LA) has attracted a great deal of attention in technology-enhanced learning (TEL) research as practitioners, institutions, and researchers are increasingly seeing the potential that LA has to shape the future TEL landscape. Generally, LA deals with the development of methods that harness educational data sets to support the learning process. This paper provides a foundation for future research in LA. It provides a systematic overview on this emerging field and its key concepts through a reference model for LA based on four dimensions, namely data, environments, context (what?), stakeholders (who?), objectives (why?), and methods (how?). It further identifies various challenges and research opportunities in the area of LA in relation to each dimension.

A process evaluation of the Houston Childhood Lead Poisoning Prevention Program, 1992-1995, was conducted. The Program's goal is to reduce lead poisoning prevalence. The study proposed to determine to what extent the Program was implemented as planned by measuring how well Program services were actually: (1) received by the intended target population; (2) delivered to children with elevated blood lead levels; (3) delivered in compliance with the Centers for Disease Control and Prevention and Program guidelines and timetables; and (4) able to reduce lead poisoning prevalence among those rescreened. Utilizing a program monitoring design, the Program's pre-collected computer records were reviewed. The study sample consisted of 820 children whose blood lead levels were above 15 micrograms per deciLiter, representing approximately 2.9% of the 28,406 screened over this period. Three blood lead levels from each participant were examined: the initial elevated result; the confirmatory result; and the next rescreen result, after the elevated confirmatory level. Results showed that the Program screened approximately 18% (28,406 of 161,569) of Houston's children under age 6 years for lead poisoning. Based on Chi-square tests of significance, results also showed that lead-poisoned participants were more likely to be younger than 3 years, male and Hispanic, compared to those not lead poisoned. The age, gender and ethnic differences observed were statistically significant (p =.01, p =.00, p =.00). Four of the six Program services: medical evaluations, rescreening, environmental inspections and confirmation, had satisfactory delivery completion rates of 71%-98%. Delivery timetable compliance rates for three of the six services examined: outreach contacts, home visits and environmental inspections were below 32%. However, dangerously elevated blood lead levels fell and lead poisoning prevalence dropped from 3.3% at initial screening to 1.2% among those rescreened, after intervention. From a public health perspective, reductions in lead poisoning prevalence are very meaningful. Based on these findings, the following are recommendations for future research: (1) integrate Program database files by utilizing a computer database management program; (2) target services at Hispanic male children under age 3 years living in the highest risk neighborhoods; (3) increase resources to: improve tracking and documentation of service delivery and provide more non-medical case management and environmental services; and (4) share the evaluation methodology/findings with the Centers for Disease Control and Prevention administrators; the implications may be relevant to other program managers conducting such assessments. ^
