Distribución geográfica e influencia del turismo sobre las paradas cardiacas en Baleares. Estrategia de salud para introducir los desfibriladores

Introducción: Las paradas cardiorrespiratorias extrahospitalarias (PCREH) son un problema de salud pública. En nuestra Comunidad Autónoma el turismo contribuye a aumentar la población. Los planes de acceso público a la desfibrilación y la instalación de desfibriladores semiautomáticos (DESA) en lugares públicos pueden contribuir a disminuir la mortalidad. Objetivo: Evaluar la distribución geográfica y la influencia del turismo sobre las PCREH. Diseño: Estudio de cohortes prospectivo. Población y ámbito: PCREH de ≥ 14 años atendidos por el 061 durante el bienio 2009-2010, en el territorio de las Islas Baleares Principales variables de interés: Tiempo respuesta del SEM061, edad, sexo, lugar, municipio, presencia de testigo, utilización DESA, ritmo inicial, recuperación del pulso, sospecha etiológica y muerte. Resultados: Se estudiaron 542 PCR (34/100.000 habitantes), de los que 63 (11,6 %) fueron dados de alta hospitalaria. La edad media fue 60,48 años, 75,9% varones. En los meses de febrero, junio y agosto ocurrieron más PCR. Excluyendo Palma, Calviá e Ibiza, los municipios costeros representaron el 50% del total de PCREH. El 45,4% ocurrieron en domicilio, el 21,5% vía pública y el 17% lugares turísticos. La PCREH fue presenciada en 76,2%. La mediana del tiempo de respuesta del SEM-061 fue 12 minutos. La desfibrilación se realizó en 32%. El DESA se utilizó en 28,2% y desfibriló en el 50%. Fueron factores pronósticos independientes la edad (p=0,056), parada presenciada (p=0,024), duración RCP básica < 10 min. (p=0,057), duración RCP avanzada < 20 min. (p=0,001) y ritmos desfibrilables (p=0,021). Conclusión: Las PCREH ocurren con frecuencia en municipios costeros, en lugares y establecimientos turísticos y durante meses con más afluencia de población turística. En estos lugares debería plantearse la instalación de desfibriladores semiautomáticos.Introduction: Cardiac arrests (CA) are a public health problem. In our region, tourism is a factor that contributes to increase the population, all along the year, especially in summertime. Strategies of public access to defibrillation bystander and the installation of automated external defibrillators (AED) in public settings may contribute to decrease mortality. Objective: To assess the geographic distribution and the influence of tourism in CA Design: Prospective cohort study. Population and setting: CA in patients over 14 years old attended by emergency-medical-services (EMS) in the period 2009-2010 in the Balearic Islands. Primary variables of interest: Arrival time of the EMS, age, sex, location, town, witnessed AC, use of AED, initial rhythm, return of spontaneous circulation, suspected etiology and death. Results: We studied 542 AC (34/100.000 habitants). 63 of them (11.6%) were discharged Hospital. The mean age was 60.5 years (SD15.8). 75.9% were males. February, June and August were the months with more AC. Excluding the towns of Palma, Calviá and Ibiza, the 50% of all CA occurred in coast villages. 45,4% occurred at home, 21.5% street and 17% tourist location. Witnessed AC was present in 76.2%. The median arrival time of the EMS-061 was 12 minutes (SD20.12). Defibrillation was performed in 32%. AED was used in 28.2% and 50% defibrillated. The independent prognostic factors were: age (p =0.056), witnessed AC (p=0.024), bystander CPR <10 min (p =0.057), EMS_061 CPR <20 min (p =0.001) and shockable rhythm (p=0.021). Conclusion: The cardiac arrests occurred frequently in coast and in touristic sites and the months with more tourist population. In these places the installation of AED may contribute to decrease mortality

Real-time audio interaction in serious games for music learning

In this LBD, we present several Apps for playing while learning music or for learning music while playing. The core of all the games is based on the good performance of the real-time audio interaction algorithms developed by the ATIC group at Universidad de Ma ́laga (SPAIN).Universidad de Málaga.

Gating the charge state of a single molecule by local electric fields

The electron acceptor molecule TCNQ is found in either of two distinct integer charge states when embedded into a monolayer of a charge transfer-complex on a gold surface. Scanning tun- neling spectroscopy measurements identify these states through the presence/absence of a zero-bias Kondo resonance. Increasing the (tip-induced) electric field allows us to reversibly induce the ox- idation/reduction of TCNQ species from their anionic or neutral ground state, respectively. We show that the different ground states arise from slight variations in the underlying surface potential, pictured here as the gate of a three-terminal device.Comment: 5 pages, 4 figure

Modeling spectral changes in singing voice for pitch modification

We present an advanced method to achieve natural modifications when applying a pitch shifting process to singing voice by modifying the spectral envelope of the audio ex- cerpt. To this end, an all-pole spectral envelope model has been selected to describe the global variations of the spectral envelope with the changes of the pitch. We performed a pitch shifting process of some sustained vowels with the envelope processing and without it, and compared both by means of a survey open to volunteers in our website.Universidad de Málaga.

Android app for automatic music composition

In this contribution, we present an Android App that generates music automatically replicating a specific contemporary genre, specifically rock music. The composition system is based on the analysis of a set of songs of the desired genre. The analysis results the automatic composition algorithm requires are exported to a JSON file that can be readily imported and parsed. The Android App developed creates a symbolic representation of the music generated for drums, bass and rhythm guitar that can be exported to a MIDI file or audio waveform. The evaluation results show that the automatic compositions generated are not distinguished amongst other excerpts created by human composers.Universidad de Málaga.

Conducting a virtual ensemble with a kinect device

This paper presents a gesture-based interaction technique for the implementation of an orchestra conductor and a virtual ensemble, using a 3D camera-based sensor to capture user’s gestures. In particular, a human-computer interface has been developed to recognize conducting gestures using a Microsoft Kinect device. The system allows the conductor to control both the tempo in the piece played as well as the dynamics of each instrument set independently. In order to modify the tempo in the playback, a time-frequency processing-based algorithmis used. Finally, an experiment was conducted to assess user’s opinion of the system as well as experimentally confirm if the features in the system were effectively improving user experience or not.This work has been funded by the Ministerio de Economia y Competitividad of the Spanish Government under Project No. TIN2010-21089-C03-02 and Project No. IPT-2011-0885-430000 and by the Junta de Andalucia under Project No. P11-TIC-7154.

Percepción de niños de contextos rurales y urbanos sobre separación y divorcio

Este trabajo tiene dos objetivos: por un lado, analizar qué percepción y valoración hacen los niños y niñas de contextos rurales y urbanos sobre la separación y/o divorcio de los padres y sus efectos en los hijos y, por otro, conocer si existen diferencias en función del entorno al que se pertenezca. Para ello, se llevó a cabo una investigación con 460 niños y niñas de contextos rurales y urbanos con edades comprendidas entre los 7 y los 17 años que cursaban estudios en niveles de Primaria y Secundaria. Para este trabajo nos centraremos exclusivamente en el análisis de la variable residencia en contextos rurales o urbanos. Los resultados nos indican que de forma significativa, los que residen en contextos urbanos hacen una valoración más negativa del divorcio frente a los que residen en contextos rurales, mientras que los de los contextos rurales consideran que se producen más efectos negativos en los hijos.This paper has two objectives: first, to analyze what perception and assessment children in rural and urban settings have on the separation and / or divorce of parents and their effects on children; and, on the other side, determine whether there are differences depending on the environment to which it belongs. A research with 460 children from rural and urban contexts aged 7 to 17 who were studying in elementary and secondary levels was carried out. For this work we will focus exclusively on the analysis of the variable residence in rural or urban settings. The results indicate that significantly, those living in urban settings make a more negative assessment of divorce compared to those living in rural contexts, while those living in rural contexts consider that the effects on children are more negative.peerReviewe

Virtual Conductor for String Quartet Practice

This paper presents a system that emulates an ensemble conductor for string quartets. This application has been developed as a support tool for individual and group practice, so that users of any age range can use it to further hone their skills, both for regular musicians and students alike. The virtual conductor designed can offer similar indications to those given by a real ensemble conductor to potential users regarding beat times, dynamics, etc. The application developed allows the user to rehearse his/her performance without the need of having an actual conductor present, and also gives access to additional tools to further support the learning/practice process, such as a tuner or a melody evaluator. The system developed also allows for both solo practice and group practice. A set of tests were conducted to check the usefulness of the application as a practice support tool. A group of musicians from the Chamber Orchestra of Malaga including an ensemble conductor tested the system, and reported to have found it a very useful tool within an educational environment and that it helps to address the lack of this kind of educational tools in a self-learning environment.This work has been funded by the Ministerio de Economia y Competitividad of the Spanish Government under Project No. TIN2010-21089-C03- 02 and Project No. IPT-2011-0885-430000 and by the Ministerio de Industria, Turismo y Comercio under Project No. TSI-090100-2011-25
