Coaches' use of and impressions of computer-mediated communication (CMC) media /

The study examined coaches' usage of text-based computer-mediated communication (CMC) media (e.g., text-messaging, email) in the coach-player relationship. Data were collected by surveying Ontario-based male baseball coaches (n = 86) who coached players between 15 and 18 years old. Predictions were made regarding how demographic factors such as age and coaching experience affected coaches' CMC use and opinions. Results indicated that over 76% of respondents never used any CMC media other than email and team websites in their interactions with players. Results also revealed that coaches' usage rates contrasted with their opinion of the usefulness of the media, and their perception of players' use of the media. Coaches characterized most CMC media as limited, unnecessary, and sometimes inappropriate. Additional research should explore players' CMC usage rates and possible guidelines for use of the new media in authority relationships. Academia needs to keep pace with the developments in this area.

Adaptive intelligent agent approach to guide the web navigation on the PLAN-G distance learning platform

Hypermedia systems based on the Web for open distance education are becoming increasingly popular as tools for user-driven access learning information. Adaptive hypermedia is a new direction in research within the area of user-adaptive systems, to increase its functionality by making it personalized [Eklu 961. This paper sketches a general agents architecture to include navigational adaptability and user-friendly processes which would guide and accompany the student during hislher learning on the PLAN-G hypermedia system (New Generation Telematics Platform to Support Open and Distance Learning), with the aid of computer networks and specifically WWW technology [Marz 98-1] [Marz 98-2]. The PLAN-G actual prototype is successfully used with some informatics courses (the current version has no agents yet). The propased multi-agent system, contains two different types of adaptive autonomous software agents: Personal Digital Agents {Interface), to interacl directly with the student when necessary; and Information Agents (Intermediaries), to filtrate and discover information to learn and to adapt navigation space to a specific student

Evaluación del programa de vigilancia centinela de influenza y otros virus respiratorios 1997- 2007 Colombia

La influenza es una entidad clínica, que es causada por los virus de la influenza A, B y C del género Influenza. El virus de la influenza A se clasifica en subtipos, con base en 2 antígenos de superficie: la hemaglutinina y la neuraminidasa. La respuesta inmune frente a estos antígenos (especialmente frente a la hemaglutinina), disminuye la probabilidad de infección, así como la severidad del cuadro clínico. La intención de este trabajo es describir el funcionamiento del programa de vigilancia centinela de influenza y otros virus respiratorios en Colombia, que permite identificar en que medida se alcanza la finalidad de esta actividad y que dificultades en general afectan su funcionamiento.

Closely coupled behaviour in networked robot systems

Multiple cooperating robot systems may be required to take up a closely coupled configuration in order to perform a task. An example is extended baseline stereo (EBS), requiring that two robots must establish and maintain for a certain period of time a constrained kinematic relationship to each other. In this paper we report on the development of a networked robotics framework for modular, distributed robot systems that supports the creation of such configurations. The framework incorporates a query mechanism to locate modules distributed across the two robot systems. The work presented in this paper introduces special mechanisms to model the kinematic constraint and its instantiation. The EBS configuration is used as a case study and experimental implementation to demonstrate the approach.

O período do estudo se dá entre janeiro de 2010 e julho de 2011. O SisTEx é melhor caracterizado pelo Centro Integrado de Telemática do Exército (CITEx), pelos Centros de Telemática de Área (CTA) e pelos Centros de Telemática (CT), subordinados ao Departamento de Ciência e Tecnologia (DCT) e dispostos ao longo de todo o território nacional. O estudo trata do conceito de produtividade do trabalho e do processo de capacitação no SisTEx. Fala sobre as áreas do conhecimento de interesse sistêmico e das áreas estratégicas que devem ser atendidas com capacitações, mostrando os resultados que surgiram em função das capacitações realizadas. Propõe sugestões para alinhar as necessidades de capacitação com as áreas estratégicas, destacando a importância das capacitações no planejamento estratégico, passando pelos interesses individuais. Relaciona estratégias que representam um diferencial competitivo na agregação de valor aos usuários. Traz comentários sobre a utilização do ensino a distância(EAD) e presencial para realização das capacitações. Trata da interferência das capacitações na produtividade e na percepção sobre o retorno do investimento (ROI). Relaciona, ainda, as capacidades do SisTEx com os estudos de inovação tecnológica no setor de serviços. Destaca as capacitações realizadas na áreas da segurança da informação e defesa cibernética. Considera que é possível melhorar a produtividade do trabalho em função das capacitações que ocorrem no SisTEx, que contribuem como um vetor de modernidade e transformação que agem diretamente no processo produtivo, proporcionando assim uma aceleração no desenvolvimento da qualidade dos serviços de TI prestados. Traz recomendações de estudos futuros para verificar a velocidade de acumulação das capacidades tecnológicas, o uso do EAD para capacitações de maior complexidade técnica e a criação de métricas para cálculo efetivo do ROI. Para tal, foi feito um estudo bibliográfico sobre a produtividade do trabalho e o processo de capacitação do SisTEx. O método adotado foi o do estudo de caso. Foram feitos questionamentos (survey) e enquetes/votações (poll) que foram aplicados nos chefes, exchefes de CTA/CT e nos discentes do SisTEx, militares que realizaram capacitações no período considerado.

A clinical decision support system for cancer diseases

The second main cause of death in Brazil is cancer, and according to statistics disclosed by National Cancer Institute from Brazil (INCA) 466,730 new cases of cancer are forecast for 2008. The analysis of tumour tissues of various types and patients' clinical data, genetic profiles, characteristics of diseases and epidemiological data may lead to more precise diagnoses, providing more effective treatments. In this work we present a clinical decision support system for cancer diseases, which manages a relational database containing information relating to the tumour tissue and their location in freezers, patients and medical forms. Furthermore, it is also discussed some problems encountered, as database integration and the adoption of a standard to describe topography and morphology. It is also discussed the dynamic report generation functionality, that shows data in table and graph format, according to the user's configuration. © ACM 2008.

Design de Relações entre tecnologias amigáveis e sociabilidades virtuais: um novo campo de investigação para o Design

The Digital Age, with its new interactive and converging technologies, stimulates original forms of sociability, which are interconnected, intercommunicating and virtualized through hyperscreens. Another kind of interaction arises from the digitization and new speeds of contemporary communicative process. With the new order of knowledge, it is now possible to transgress the limits of physical space and linear time sequence, through the collective development of content through such telematics networks. Youth gives voice to a new type of user, or a social actor, whose thinking is connected to other communication habits, consolidating singular cultural standards, demanding new languages and skills. Here, we address the nature of this Design of new relations, interactions, behaviors and social systems that emerge in the so called Information Society.

Prüftechnik für RFID bei Hochgeschwindigkeitsanwendungen im Transportwesen

Im Rahmen des Forschungsprojektes TagDrive wird die Applikation von passiven Transpondern auf 13,56 MHz-Basis untersucht, die auf der Fahrbahn befestigt und zur Spurführung und Navigation von Fahrzeugen verwendet werden. Um den Einsatz von Folientranspondern (Smart Labels) bei hohen Fahrzeuggeschwindigkeiten in Zusammenhang mit Transponderlesegeräten am Fahrzeug zu testen, wurde ein Hochgeschwindigkeitsprüfstand für Relativgeschwindigkeiten zwischen Transponder und Lesegerät von bis zu 100 km/h entwickelt und Versuche bei variierenden Leseabständen durchgeführt. Für mechanische Prüfungen der applizierten Transponder inklusive Gehäuse wurden Druckprüfungen mit Hilfe einer servohydraulischen Prüfeinrichtung durchgeführt und ein neuer pneumatischer Prüfstand entwickelt, der den Überrollvorgang durch ein Rad nachbildet. Für klimatische Tests unter anderem nach DIN EN 60068-2-67 bzw. IEC 68-2-67 wurde ein Klimaschrank verwendet.

A simplified energy consumption model for fiber-based Next Generation Access Networks

ICTs account nowadays for 2% of total carbon emissions. However, in a time when strict measures to reduce energyconsumption in all the industrial and services sectors are required, the ICT sector faces an increase in services and bandwidth demand. The deployment of NextGenerationNetworks (NGN) will be the answer to this new demand and specifically, the NextGenerationAccessNetworks (NGANs) will provide higher bandwidth access to users. Several policy and cost analysis are being carried out to understand the risks and opportunities of new deployments, though the question of which is the role of energyconsumption in NGANs seems off the table. Thus, this paper proposes amodel to analyze the energyconsumption of the main fiber-based NGAN architectures, i.e. Fiber To The House (FTTH) in both Passive Optical Network (PON) and Point-to-Point (PtP) variations, and FTTx/VDSL. The aim of this analysis is to provide deeper insight on the impact of new deployments on the energyconsumption of the ICT sector and the effects of energyconsumption on the life-cycle cost of NGANs. The paper presents also an energyconsumption comparison of the presented architectures, particularized in the specific geographic and demographic distribution of users of Spain, but easily extendable to other countries.
