Modelo para la creación de un portal en internet que les facilite a los laboratorios farmaceúticos la promoción médica a través del uso de medios virtuales

La presente investigación se realizó con el propósito de desarrollar un modelo que fuera la base para que los laboratorios farmacéuticos puedan orientar su promoción médica hacia el uso de los recursos tecnológicos actuales como es el internet. Además de proveer un mapa conceptual de los pasos que deben seguir los laboratorios para pasar de los medios tradicionales de promoción médica (Brick) a los medios virtuales e interactivos (Click) a través de la red, es decir, actualmente la promociónmédica se hace a través de los canales tradicionales de comercialización; a esta forma la llamamos "Brick", pero nuestra propuesta permite crear una estrategia para que el laboratorio transforme la promoción médica a través de las tecnologías de comunicación, como el internet, creando un nuevo canal de comercialización, "Click", virtual, en línea. El modelo puede ser aplicado por cualquier laboratorio farmacéutico y no tiene ninguna exclusividad, puesto que es genérico; los principios aplicadosson de conocimiento público. Lo que haría la diferencia entre unportal y otro sería la forma como cada laboratorio enfrente el diseño y la implementación del mismo.

Efectos del terreno en la propagación electromagnética en entornos urbanos sobre la región andina, usando el modelo COST 231-Walfisch-Ikegami y herramientas de planificación basadas en GIS

El presente artículo hace parte del desarrollo de un algoritmo que considera la influencia del relieve en la propagación electromagnética para un entorno semi-urbano, trabajando en la banda de UHF (300MHz-3GHz) utilizada en los actuales y futuros sistemas de comunicación inalámbricos (i.e. 800-900MHz en sistemas DAMPS/US-TDMA/IS-136 y GSM). El modelo base, el COST231-Walfisch- Ikegami, empleado en la investigación,demostró beneficios, junto con los Sistemas de Información Geográfica (SIG) y las Herramientas de Planificación, para el desarrollo de los estudios de propagación, estimación de coberturas y análisis de los principales factores que afectan la planificación de un sistema móvil celular. Aquí se describen los conceptos básicos utilizados para el desarrollo del algoritmo aplicado, las consideraciones sobre las cuales se llevaron a cabolas campañas de medidas y el proceso de validación de resultados que comprueban la utilidad del algoritmo desarrollado para la predicción de Path Loss. El trabajo se basó en la fusión del modelo de propagación COST231-Walfisch-Ikegami con laHerramienta de Planificación Cell-View (fundamentada en el SIG ArcView) y la realización de mediciones en la ciudad de Bucaramanga con una unidad móvil de radiocomunicacióny control del espectro radioeléctrico de propiedad del Ministerio de Comunicaciones de Colombia, seccional Bucaramanga. El estudio llevado a cabo para la banda del sistema IS- 136, mostró resultados de simulación y validación que permiten corroborarlas aproximaciones empleadas.

An Analysis of the Implementation and Perceived Effectiveness of the SchoolMAX Family Portal

ABSTRACT Title of Document: AN ANALYSIS OF THE IMPLEMENTATION AND PERCEIVED EFFECTIVENESS OF THE SCHOOLMAX FAMILY PORTAL Warren Wesley Watts, Doctor of Education, 2015 Directed By: Margaret J. McLaughlin, Ph.D. Department of Counseling, Higher Education and Special Education School districts have spent millions of dollars implementing student information systems that offer family portals with web-based access to parents and students. One of the main purposes of these systems is to improve school-to-home communication. Research has shown that when school-to-home communication is implemented effectively, parent involvement improves and student achievement increases (Epstein, 2001). The purpose of the study was to (a) understand why parents used or refrained from using the family portal and (b) determine what barriers to use might exist. To this end, this descriptive study identified the information parent users accessed in the SchoolMAX family portal, determined how frequently parents accessed the portal, and ascertained whether parents perceived an increase in communication with their children about academic matters after they began accessing the portal. Finally, the study sought to identify whether barriers existed that prevented parents from using the family portal. The inquiry employed three data sources to answer the aforementioned queries. These sources included (a) a survey sent electronically to 19,108 parents who registered online for the SchoolMAX family portal; (b) SchoolMAX portal usage data from the student information system for system usage between January 1, 2015 and June 30, 2015; and (c) a paper survey sent to 691 parents of students that had never used the SchoolMAX family portal in one elementary school, one middle school and one high school that were representative of other schools in the district. Survey results indicated that parents at all grade levels used the family portal. Usage data also confirmed that approximately 19% of the students had parents who monitored their progress through the family portal. Usage data also showed that parents were monitoring approximately 25% of students in secondary schools (6th – 12th grade) and 16% of students in elementary schools. Of the wide menu of resources available through the SchoolMAX family portal, parents used three areas most frequently: attendance, daily grades, and report cards. Approximately 70% of parents responded that their communication had improved with their children about academic matters since they started using the SchoolMAX family portal, and 90% of parents responded that the SchoolMAX family portal was an effective or somewhat effective tool. Parents also expressed interest in the addition of additional information to the SchoolMAX family portal. Specifically, the top three additions parents wanted to see included homework assignments, high stakes test scores, and graduation requirements. Parents also reported that 92% of them spoke to their children at least 2 to 3 times per week about academics. Due to the low response rate of the parent non-user survey, potential barriers to using the SchoolMAX family portal could not be addressed in this study. However, this issue may be a useful research topic in a future study. Keywords: school to home communication, student information systems, family portal, parent portal

Effect of portal hypertension in the small bowel: an endoscopic approach

BACKGROUND AND AIM: The effects of portal hypertension in the small bowel are largely unknown. The aim of the study was to prospectively assess portal hypertension manifestations in the small bowel. METHODS: We compared, by performing enteroscopy with capsule endoscopy, the endoscopic findings of 36 patients with portal hypertension, 25 cirrhotic and 11 non-cirrhotic, with 30 controls. RESULTS: Varices, defined as distended, tortuous, or saccular veins, and areas of mucosa with a reticulate pattern were significantly more frequent in patients with PTH. These two findings were detected in 26 of the 66 patients (39%), 25 from the group with PTH (69%) and one from the control group (3%) (P < 0.0001). Among the 25 patients with PTH exhibiting these patterns, 17 were cirrhotic and 8 were non-cirrhotic (P = 0.551). The presence of these endoscopic changes was not related to age, gender, presence of cirrhosis, esophageal or gastric varices, portal hypertensive gastropathy, portal hypertensive colopathy, prior esophageal endoscopic treatment, current administration of beta-blockers, or Child-Pugh Class C. More patients with these endoscopic patterns had a previous history of acute digestive bleeding (72% vs. 36%) (P = 0.05). Active bleeding was found in two patients (5.5%). CONCLUSIONS: The presence of varices or areas of mucosa with a reticulate pattern are manifestations of portal hypertension in the small bowel, found in both cirrhotic and non-cirrhotic patients. The clinical implications of these findings, as regards digestive bleeding, are uncertain, although we documented acute bleeding from the small bowel in two patients (5.5%).

W-CDMA capacity analysis using GIS based planning tools and MATLAB simulation

The evolution of cellular systems towards third generation (3G) or IMT-2000 seems to have a tendency to use W-CDMA as the standard access method, as ETSI decisions have showed. However, there is a question about the improvements in capacity and the wellness of this access method. One of the aspects that worry developers and researchers planning the third generation is the extended use of the Internet and more and more bandwidth hungry applications. This work shows the performance of a W-CDMA system simulated in a PC using cover maps generated with DC-Cell, a GIS based planning tool developed by the Technical University of Valencia, Spain. The maps are exported to MATLAB and used in the model. The system used consists of several microcells in a downtown area. We analyse the interference from users in the same cell and in adjacent cells and the effect in the system, assuming perfect control for each cell. The traffic generated by the simulator is voice and data. This model allows us to work with coverage that is more accurate and is a good approach to analyse the multiple access interference (MAI) problem in microcellular systems with irregular coverage. Finally, we compare the results obtained, with the performance of a similar system using TDMA.

Capacity analysis in CDMA systems using GIS based planning tools

We show a simulation model for capacity analysis in mobile systems using a geographic information system (GIS) based tool, used for coverage calculations and frequency assignment, and MATLAB. The model was developed initially for “narrowband” CDMA and TDMA, but was modified for WCDMA. We show also some results for a specific case in “narrowband” CDMA

Some parameters that affect CDMA capacity analysis. Results using GIS based simulation

In previous papers we describe a model for capacity analysis in CDMA systems using DC-Cell, a GIS based planning tool developed at Universidad Politecnica de Valencia, and MATLAB. We show some initial results of that model, and now, we are exploring different parameters like cell size, proximity between cells, number of cells in the system and “clustering” CDMA in order to improve the planning process for third generation systems. In this paper we show the results for variations of some of these parameters, specifically the cell size and number of cells. In CDMA systems is quite common to suppose only one carrier frequency for capacity estimation, and it is intuitive to think that for more base stations, mean more users. However the multiple access interference problem in CDMA systems could establish a limit for that supposition in a similar way that occurs in FDMA and TDMA systems.

Up-Link/Down-Link capacity Unbalance analysis in UMTS using a GIS based Planning Tool and MATLAB simulation

Capacity analysis using simulation is not a new thing in literature. Most of the development process of UMTS standardization have used simulation tools; however, we thing that the use of GIS planning tools and matrix manipulation capacity of MATLAB can show us different scenarios and make a more realistic analysis. Some work is been doing in COST 273 in order to have more realistic scenarios for UMTS planning. Our work initially was centered in uplink analysis, but we are now working in downlink analysis, specifically in two areas: capacity in number of users for RT and NRT services, and Node B power. In this work we will show results for up-link capacity and some results for downlink capacity and BS power consumption.

Análisis de capacidad en sistemas CDMA y WCDMA, usando herramientas de planificación basadas en GIS y dinámica poliédrica

En este momento están entrando en operación los primeros sistemas UMTS en Europa, y están operando en varios países del mundo sistemas CDMA-2000 1xRTT, y aunque existen muchos trabajos publicados sobre la capacidad de estos sistemas, prácticamente todo lo existente se basa en el comportamiento de sistemas ideales que consideran celdas hexagonales o circulares y propagación basada en exponente inverso de la distancia y poco es lo que hay sobre el comportamiento real de dichos sistemas en entornos reales.

Sobre el exponente de pérdidas de propagación, es bien conocido que este afecta la capacidad de los sistemas CDMA; sin embargo hasta ahora no se ha considerado el efecto de los modelos de propagación que tienen en cuenta la difracción y otros fenómenos más cercanos a la realidad, y por lo tanto no se ha considerado el efecto del entorno urbano y el terreno sobre la capacidad real de los sistemas basados en CDMA.

A versão atual da TCA inclui 1094 alimentos (crus, cozinhados e processados). É uma iniciativa do Instituto Ricardo Jorge, através do seu Departamento de Alimentação e Nutrição, em colaboração com a Associação dos Armadores de Pesca Local e Artesanal do Centro Sul e a Docapesca. Nesta primeira edição da iniciativa será apresentado o grupo do pescado, alimento-chave no padrão de alimentação mediterrânico.

PORTAL DE PERIÓDICOS DA CAPES: UMA POLÍTICA PÚBLICA DE ACESSO À INFORMAÇÃO CIENTÍFICA E TECNOLÓGICA

Apresenta as políticas públicas de acesso à informação científica, destacando o insigne papel desempenhado pelo Portal de Periódicos da Coordenação Nacional de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). O estudo trata-se de uma pesquisa exploratória e bibliográfica. Aponta o Portal como redutor das desigualdades regionais relacionadas ao acesso à Informação em Ciência e Tecnologia, disponibilizando periódicos científicos veiculados aos avanços e discussões constituídas no contexto acadêmico nos diversos campos do conhecimento. Conclui que o Portal atua como importante instrumento no avanço da comunicação científica, subsidiando e promovendo o acesso à Informação em Ciência e Tecnologia em tempo real, disponibilizando aos pesquisadores grande fatia da produção científica internacional e nacional atualizada, propiciando o avanço da pós-graduação brasileira em nível stricto sensu. Contudo, por outro lado, deve existir um contínuo trabalho da CAPES de modernização da plataforma, mediante a aquisição de materiais informacionais atualizados com novos conteúdos e melhoria da interface.
