Email is one of common communication methods between people on the Internet. However, the increase of email misuse/abuse has resulted in an increasing volume of spam emails over recent years. An experimental system has been designed and implemented with the hypothesis that this method would outperform existing techniques, and the experimental results showed that indeed the proposed ontology-based approach improves spam filtering accuracy significantly. In this paper, two levels of ontology spam filters were implemented: a first level global ontology filter and a second level user-customized ontology filter. The use of the global ontology filter showed about 91% of spam filtered, which is comparable with other methods. The user-customized ontology filter was created based on the specific user's background as well as the filtering mechanism used in the global ontology filter creation. The main contributions of the paper are (1) to introduce an ontology-based multilevel filtering technique that uses both a global ontology and an individual filter for each user to increase spam filtering accuracy and (2) to create a spam filter in the form of ontology, which is user-customized, scalable, and modularized, so that it can be embedded to many other systems for better performance.

La evolución de Internet es continua y parece no tener fin, aunque con la llegada de la Web 3.0 podría afirmarse que Internet es lo que sus creadores pretendían que fuera desde un primer momento: una extraordinaria e inmensa base de datos organizada, comprensible y de fácil acceso, características todavía no alcanzadas. Las novedades y los servicios incorporados por la Web 3.0 redundarán, en primer lugar, en un mejor acceso, más rápido y seguro a la información de calidad y, en segundo lugar, dotarán de una mayor personalización a los servicios sanitarios a los que acceden los usuarios de Internet, y evitarán información no relevante que contenga recomendaciones de salud equívocas, falsas o peligrosas. Sin embargo, estos cambios deberán acompañarse de los requerimientos legales propios de la sociedad de la información y de los aspectos éticos relacionados con la atención médica, lo que garantiza y contribuye a mejorar en cualquier caso la relación médico-paciente(AU)
The development of the Internet is continuous and appears to be never-ending, although with the arrival of Web 3.0 it could be said that the Internet is what its creators intended it to be from the first moment, an extraordinary and immense organised, understandable, and easy to access data base, characteristics still not achieved. The innovations and services included in Web 3.0 will result, in the first place, in better, faster and safer access to quality information. In the second place it should provide better personalisation of the health services that Internet users access, avoiding irrelevant information that may contain wrong, false and dangerous recommendations. However, these changes will have to be accompanied by the legal requirements common to the information society, by the ethical aspects associated with medical care, guaranteeing and contributing, in all cases, to improving the doctor-patient relationship(AU)

Recent developments in the area of micro-sensor devices have accelerated advances in the sensor networks field leading to many new protocols specifically designed for wireless sensor networks (WSNs). Wireless sensor networks with hundreds to thousands of sensor nodes can gather information from an unattended location and transmit the gathered data to a particular user, depending on the application. These sensor nodes have some constraints due to their limited energy, storage capacity and computing power. Data are routed from one node to other using different routing protocols. There are a number of routing protocols for wireless sensor networks. In this review article, we discuss the architecture of wireless sensor networks. Further, we categorize the routing protocols according to some key factors and summarize their mode of operation. Finally, we provide a comparative study on these various protocols.

Objetivo: En este artículo se expone el desarrollo de un modelo de aprendizaje electrónico realizado en la Escuela Nacional de Sanidad por especialistas de diferentes disciplinas (salud pública, pedagogía, informática, administración, gestión y calidad).Material y métodos: El proyecto se dividió en 4 fases: conceptualización, análisis de recursos y funciones, elaboración de contenidos y composición del curso. Resultados: La experiencia nos permitió identificar los procedimientos institucionales requeridos para la realización de cursos por Internet y obtener una serie de documentos (modelo pedagógico, guía de elaboración de materiales, pautas para elaborar la guía de estudio, pautas para los profesores y tutores y manual de uso de la plataforma) que constituyen la base de nuestro modelo de formación virtual. Asimismo, nos permitió constatar la complejidad de este tipo de formación, la cantidad de recursos que requiere y los enormes esfuerzos de coordinación y de trabajo en grupo que son necesarios para obtener un producto final de calidad. No obstante, a pesar de que los esfuerzos iniciales son muy grandes en relación con los resultados obtenidos, con el tiempo esa relación se invierte. Conclusiones: La formación a través de Internet es una apuesta de futuro que se rentabiliza y tiene sentido a largo plazo y que siempre debe ponerse en marcha con el objetivo de agregar valor a las posibilidades de formación ya existentes. No se trata de transformar una formación en otra, sino de crear nuevas posibilidades y oportunidades de aprendizaje mediante el uso de las nuevas tecnologías de la información y comunicación. (AU)

En el presente estudio, se analizan los patrones de uso de Internet y de sus recursos específicos como páginas web, correo electrónico y chats específicos. Para ello se ha contado con una muestra de 1301 estudiantes universitarios de ambos sexos y se analizaron las características sociodemográficas, los parámetros de uso de Internet de forma global y específica, los motivos y la interferencia del uso en la vida cotidiana de los sujetos. Los resultados muestran que el 33,9 por ciento de la muestra lleva conectándose a la red entre 1 y 2 años y el 23,1 por ciento afirma hacerlo en un intervalo de entre 2 y 5 años; el 43,3 por ciento de los universitarios del estudio prefiere conectarse por las tardes, el 39 por ciento por las noches y el 17,7 por ciento por las mañanas haciéndolo generalmente desde su domicilio. Un alto porcentaje de la muestra realiza un uso moderado de Internet al analizar el tiempo de conexión (invierten menos de 4 horas semanales) y tan sólo un 1 por ciento afirma invertir un mínimo de 5 horas diarias durante los siete días de la semana y sólo el 17 por ciento afirma percibir algún tipo de interferencia utilizando los recursos de Internet en su vida cotidiana. En cuanto a la variable sexo son los hombres los que dedican más tiempo a la semana en la utilización de cualquiera de los recursos de Internet. En general, los estudiantes encuestados realizan un uso muy moderado de Internet dedicando un promedio semanal que va de 11 a 20 horas lo que nos indicaría que no hay un uso abusivo o patológico cercano a la adicción, siendo un grupo reducido de jóvenes los que sí estarían próximos a este tipo de psicopatología (AU)
In this study, the Internet usage patterns and resources, such as websites, e-mail, and specific chats, were analysed in a sample of 1301 university students of both sexes. Their sociodemographic characteristics, global and specific Internet usage parameters, motives and the interference of such use in their daily lives were studied. The results show that 33.9% of the sample had been using the Internet between 1 and 3 years, and 23.1% reported using Internet for a period ranging between 2 and 5 years; 43.3% of the university students preferred connecting to Internet in the afternoon, 39% at night, and 17.7% in the morning, generally from home. On analyzing connection duration, a high percentage of the sample made moderate use of Internet (with less than 4 hours per week), and only 1% reported spending a minimum of 5 hours per day, seven days a week, and only 17% admitted perceiving some kind of interference in their daily lives from the use of Internet resources. By gender, men spend more time per week than women using any of the Internet resources. In general, the students surveyed use the Internet very moderately, devoting a average weekly period ranging from 11 to 20 hours, which would indicate that there is no abusive or pathological use, approaching addiction, of the Internet. Only a reduced group of young people came near to this kind of psychopathology (AU)

Las organizaciones sanitarias se basan en la gestión del conocimiento, por lo que la información constituye un valor clave, tanto por la cantidad que genera el acceso a otras fuentes de conocimiento como por su necesidad para la toma de decisiones. Esto lleva a diseñar una serie de sistemas de información interrelacionados, apoyados en el desarrollo de tecnologías de la información y de la comunicación, y adecuados para atender las necesidades de los distintos componentes de la organización, tanto de los profesionales sanitarios como de los distintos niveles de dirección y gestión o de la población atendida. Este desarrollo, en el Insalud, se basa en la puesta en marcha de una serie de proyectos que abarcan la identificación de la población atendida (a través de la tarjeta sanitaria individual), herramientas precisas para la asistencia sanitaria y su gestión (renovación tecnológica de hospitales, informatización de centros de salud), gestión de prestaciones, presupuestos, etc., así como la habilitación de las infraestructuras necesarias como la red corporativa de comunicaciones, telemedicina, acceso a Internet y otros servicios como correo electrónico. Todos estos proyectos, funcionantes y consolidados, están diseñados para dar respuesta a las necesidades actuales y, a la vez con una visión de futuro, ya que permiten su evolución y redimensionamiento según las nuevas necesidades (AU)

Prior to June 1997, military picture archiving and communications systems (PACS) were planned, procured, and installed with key decisions on the system, equipment, and even funding sources made through a research and development office called Medical Diagnostic Imaging Systems (MDIS). Beginning in June 1997, the Joint Imaging Technology Project Office (JITPO) initiated a collaborative and consultative process for planning and implementing PACS into military treatment facilities through a new Department of Defense (DoD) contract vehicle called digital imaging networks (DIN)-PACS. The JITPO reengineered this process incorporating multiple organizations and politics. The reengineered PACS process administered through the JITPO transformed the decision process and accountability from a single office to a consultative method that increased end-user knowledge, responsibility, and ownership in PACS. The JITPO continues to provide information and services that assist multiple groups and users in rendering PACS planning and implementation decisions. Local site project managers are involved from the outset and this end-user collaboration has made the sometimes difficult transition to PACS an easier and more acceptable process for all involved. Corporately, this process saved DoD sites millions by having PACS plans developed within the government and proposed to vendors second, and then having vendors respond specifically to those plans. The integrity and efficiency of the process have reduced the opportunity for implementing nonstandard systems while sharing resources and reducing wasted government dollars. This presentation will describe the chronology of changes, encountered obstacles, and lessons learned within the reengineering of the PACS process for DIN-PACS.
