Desde la unidad de tecnología Educativa del Departamento de Microbiología de la Universidad de Salamanca se ha hecho el esfuerzo de investigación para unir los avances tecnológicos con el mundo académico. El Web-Cd trata de ser un nuevo sistema de educación, un sistema en el que los alumnos tengan que aprender aprendiendo el uso de nuevas tecnologías, una forma activa y participativa en el que desarrollar las actividades, los ejercicios y los exámenes a través de la red.

Realizado en la Facultad de Psicología de Salamanca, por 3 profesores del centro para la asignatura de Metodología Experimental de la Licenciatura en Psicología. Se confeccionó un libro de texto para la asignatura mencionada y materiales escritos asociados a la existencia de la plataforma de enseñanza virtual. También, se desarrolló un curso de apoyo a la docencia de la citada asignatura basado en una plataforma interactiva y applets en lenguaje Java que permiten la realización de experiencias interactivas sobre temas psicológicos. El resultado del proyecto ha sido satisfactorio y puede ser de utilidad para otras titulaciones de Ciencias de la Educación las cuales aplican métodos experimentales.

La actividad se ha desarrollado en el Departamento de Informática del Instituto de Enseñanza Secundaria Ribera de Castilla. Las prácticas se han desarrollado en las aulas de informática, los objetivos han sido instalar un servidor web de ftp, news y chat, controlar el acceso a Internet. El sistema de trabajo ha sido el reparto de tareas y posteriormente la puesta en el grupo. Se elaboró un programa con los puntos a tratar, hubo reparto de tareas, se recopiló información y recursos, se hizo puesta en común en el grupo, hubo implementación y puesta en marcha de las tareas. Los resultados fueron la creación de una red segmentada en cinco subredes, distintos servidores (web, ftp, news, chat). Los materiales son: hardward PC Pentium II, y AMD con 32 o 64 MB, servidor PC a 500 MZ, placa dual 194 Mb, línea ADSL, software: distintos sistemas operativos Windows 98 SE, Windows 2000, Linux. Otras aplicaciones Sntpbeamer, Outlook Express.

Expone una práctica educativa, realizada en el colegio asturiano 'La Canal', que consiste en el uso de Internet por parte del alumnado de educación infantil. En este sentido, se proponen una serie de actividades que se localizan en la página web de este centro educativo. Estas actividades son: las rutas del aprendizaje que son guías para aprender el manejo de Internet como recurso básico; librolandia que permite divertirse y jugar a través de la lectura; y el taller de juguetes que muestra los resultados de una experiencia que pretendía enseñar al niño la idea de que los juguetes no sólo se pueden comprar sino que también se pueden realizar por uno mismo.

Medical universities and teaching hospitals in Iraq are facing a lack of professional staff due to the ongoing violence that forces them to flee the country. The professionals are now distributed outside the country which reduces the chances for the staff and students to be physically in one place to continue the teaching and limits the efficiency of the consultations in hospitals. A survey was done among students and professional staff in Iraq to find the problems in the learning and clinical systems and how Information and Communication Technology could improve it. The survey has shown that 86% of the participants use the Internet as a learning resource and 25% for clinical purposes while less than 11% of them uses it for collaboration between different institutions. A web-based collaborative tool is proposed to improve the teaching and clinical system. The tool helps the users to collaborate remotely to increase the quality of the learning system as well as it can be used for remote medical consultation in hospitals.

The construction industry has incurred a considerable amount of waste as a result of poor logistics supply chain network management. Therefore, managing logistics in the construction industry is critical. An effective logistic system ensures delivery of the right products and services to the right players at the right time while minimising costs and rewarding all sectors based on value added to the supply chain. This paper reports on an on-going research study on the concept of context-aware services delivery in the construction project supply chain logistics. As part of the emerging wireless technologies, an Intelligent Wireless Web (IWW) using context-aware computing capability represents the next generation ICT application to construction-logistics management. This intelligent system has the potential of serving and improving the construction logistics through access to context-specific data, information and services. Existing mobile communication deployments in the construction industry rely on static modes of information delivery and do not take into account the worker’s changing context and dynamic project conditions. The major problems in these applications are lack of context-specificity in the distribution of information, services and other project resources, and lack of cohesion with the existing desktop based ICT infrastructure. The research works focus on identifying the context dimension such as user context, environmental context and project context, selection of technologies to capture context-parameters such wireless sensors and RFID, selection of supporting technologies such as wireless communication, Semantic Web, Web Services, agents, etc. The process of integration of Context-Aware Computing and Web-Services to facilitate the creation of intelligent collaboration environment for managing construction logistics will take into account all the necessary critical parameters such as storage, transportation, distribution, assembly, etc. within off and on-site project.

Search has become a hot topic in Internet computing, with rival search engines battling to become the de facto Web portal, harnessing search algorithms to wade through information on a scale undreamed of by early information retrieval (IR) pioneers. This article examines how search has matured from its roots in specialized IR systems to become a key foundation of the Web. The authors describe new challenges posed by the Web's scale, and show how search is changing the nature of the Web as much as the Web has changed the nature of search

The service-oriented approach to performing distributed scientific research is potentially very powerful but is not yet widely used in many scientific fields. This is partly due to the technical difficulties involved in creating services and workflows and the inefficiency of many workflow systems with regard to handling large datasets. We present the Styx Grid Service, a simple system that wraps command-line programs and allows them to be run over the Internet exactly as if they were local programs. Styx Grid Services are very easy to create and use and can be composed into powerful workflows with simple shell scripts or more sophisticated graphical tools. An important feature of the system is that data can be streamed directly from service to service, significantly increasing the efficiency of workflows that use large data volumes. The status and progress of Styx Grid Services can be monitored asynchronously using a mechanism that places very few demands on firewalls. We show how Styx Grid Services can interoperate with with Web Services and WS-Resources using suitable adapters.
