The development of preventive and control mechanisms to nosocomial microorganisms are important efforts to develop both human and veterinary hospitals. Among those strategies aimed to reduce both pathogenic microbial flora and multidrug resistance in hospitals are the reduction of microorganisms dissemination from staff to animals, avoiding acquisition of microorganisms from hospital equipment sand infrastructure, conducting permanent cleaning, disinfection and sterilization programs; and a rational use of antimicrobials. The present document describes the fundamental principles of in hospital microbiological control, fitted to the veterinary medical context in Colombia

Video semantic content analysis framework based on ontology combined MPEG-7

The rapid increase in the available amount of video data is creating a growing demand for efficient methods for understanding and managing it at the semantic level. New multimedia standard, MPEG-7, provides the rich functionalities to enable the generation of audiovisual descriptions and is expressed solely in XML Schema which provides little support for expressing semantic knowledge. In this paper, a video semantic content analysis framework based on ontology combined MPEG-7 is presented. Domain ontology is used to define high level semantic concepts and their relations in the context of the examined domain. MPEG-7 metadata terms of audiovisual descriptions and video content analysis algorithms are expressed in this ontology to enrich video semantic analysis. OWL is used for the ontology description. Rules in Description Logic are defined to describe how low-level features and algorithms for video analysis should be applied according to different perception content. Temporal Description Logic is used to describe the semantic events, and a reasoning algorithm is proposed for events detection. The proposed framework is demonstrated in sports video domain and shows promising results

A kinetic and Kinematic analysis in two assessment situation with bench press. Free Weight vs Smith Machine. Project pilot.

En este estudio piloto se analizan algunas de las variables cinéticas y cinemáticas que pueden afectar a la situación de ejecución/evaluación del Press de Banca, en máquina Smith (PMS) vs con barra y discos (PBL). Dos sujetos entrenados participaron en esta investigación habiendo sido informados previamente de la finalidad de la misma. En dos momentos se llevó a cabo un protocolo incremental de cargas hasta alcanzar su máximo peso a desplazar en una repetición (1-RM), uno para el PMS y otro para el PBL. El Sujeto 1 (S-1) manifestó valores de fuerza de 770 y 837 N, en PBL y PMS, alcanzando este pico máximo de fuerza (PMF) a los 28 y 12 ms, respectivamente. En el caso del Sujeto 2 (S-2), los valores de PMF fueron de 693 y 849 N, empleando un tiempo en alcanzar estos PMF fue de 60 y 66 ms, en PBL y PMS, respectivamente. Se realizó un análisis detallado de las curvas de “sticking period”, las distancias de agarre e inclinación de la barra. Como conclusión más relevante de nuestro trabajo y como base para futuras investigaciones, decir que a la hora de entrenar, el ejercicio en PBL puede ser más aconsejado. Mientras que para evaluar, el ejercicio en PMS aporta información más fiable en cuanto a las variables relevantes de la fuerza.This pilot study examines the most relevant kinetic and kinematics variables in two bench press exercises; Smith Machine (PMS) vs. free weights (PBL). Two trained subjects participated in the research following informed consent. To determine the maximum load (1- RM), two incremental protocols were used for PMS and PBL. Subject 1 (S-1) produced force values of 770N and 837N, peak force of 28ms and 12ms, in PBL and PMS respectively. Values for subject 2 (S-2) were 693N and 849N, PMF of 60ms and 66ms for PBL and PMS respectively. Detailed analyses of the following variables were performed; velocity curves for each load, the “sticking period”, the distances of grip width, and changes in bar inclination during the ascent phase of the lift were examined. The key findings of this research, and the basis for future research demonstrate that PBL is recommended as a training exercise, while more reliable information regarding force variables can be attained through using PMS in measurement sessions.peerReviewe

Smartphone-Enabled Personalized Diagnostics: Current Status and Future Prospects

Biosensors; Mètodes moleculars; Diagnòstics basat en telèfons intel·ligentsBiosensores; Métodos moleculares; Diagnósticos basados en teléfonos inteligentesBiosensors; Molecular methods; Smarthphone-based diagnosticsSmartphones are becoming increasingly versatile thanks to the wide variety of sensor and actuator systems packed in them. Mobile devices today go well beyond their original purpose as communication devices, and this enables important new applications, ranging from augmented reality to the Internet of Things. Personalized diagnostics is one of the areas where mobile devices can have the greatest impact. Hitherto, the camera and communication abilities of these devices have been barely exploited for point of care (POC) purposes. This short review covers the recent evolution of mobile devices in the area of POC diagnostics and puts forward some ideas that may facilitate the development of more advanced applications and devices in the area of personalized diagnostics. With this purpose, the potential exploitation of wireless power and actuation of sensors and biosensors using near field communication (NFC), the use of the screen as a light source for actuation and spectroscopic analysis, using the haptic module to enhance mass transport in micro volumes, and the use of magnetic sensors are discussed.Financial support from the Basque Government under the ELKARTEK program is also acknowledged.

ELVIS: Entertainment-led video summaries

© ACM, 2010. This is the author's version of the work. It is posted here by permission of ACM for your personal use. Not for redistribution. The definitive version was published in ACM Transactions on Multimedia Computing, Communications, and Applications, 6(3): Article no. 17 (2010) http://doi.acm.org/10.1145/1823746.1823751Video summaries present the user with a condensed and succinct representation of the content of a video stream. Usually this is achieved by attaching degrees of importance to low-level image, audio and text features. However, video content elicits strong and measurable physiological responses in the user, which are potentially rich indicators of what video content is memorable to or emotionally engaging for an individual user. This article proposes a technique that exploits such physiological responses to a given video stream by a given user to produce Entertainment-Led VIdeo Summaries (ELVIS). ELVIS is made up of five analysis phases which correspond to the analyses of five physiological response measures: electro-dermal response (EDR), heart rate (HR), blood volume pulse (BVP), respiration rate (RR), and respiration amplitude (RA). Through these analyses, the temporal locations of the most entertaining video subsegments, as they occur within the video stream as a whole, are automatically identified. The effectiveness of the ELVIS technique is verified through a statistical analysis of data collected during a set of user trials. Our results show that ELVIS is more consistent than RANDOM, EDR, HR, BVP, RR and RA selections in identifying the most entertaining video subsegments for content in the comedy, horror/comedy, and horror genres. Subjective user reports also reveal that ELVIS video summaries are comparatively easy to understand, enjoyable, and informative
