Retribución en farmacia comunitaria. Visión en otros países
INTRODUCCIÓN La retribución, que según la RAE, es la recompensa o pago por algo, constituye un factor de máxima relevancia en la determinación de la eficiencia de una actividad. Como en cualquier actividad profesional, en la farmacia comunitaria es un determinante de la consecución de los objetivos de la misma. En base a ello, el objetivo del presente estudio es analizar la estructura de la retribución de la dispensación en la farmacia comunitaria en España, comparándola con la de otros países representativos a nivel internacional.MÉTODOS Se realizó una búsqueda en internet de las disposiciones oficiales sobre los diferentes sistemas retributivos actualmente en vigor para cada país seleccionado. Se seleccionaron las estructuras de remuneración de la farmacia comunitaria en diversos países de Europa (Alemania, Bélgica, Francia, Gran Bretaña, Holanda, Irlanda y Suiza), América (Canadá y Estados Unidos) y Australia (Australia).RESULTADOS En España, la retribución de la dispensación en la farmacia comunitaria se basa exclusivamente en un porcentaje sobre el precio de venta del medicamento. En los demás países analizados, dicha retribución ha ido evolucionando hacia el pago de honorarios por las intervenciones farmacéuticas desarrolladas, desligándose así del precio del medicamento y asimilando el trabajo del farmacéutico más a una actividad profesional que mercantil.CONCLUSIONES El sistema retributivo de la dispensación de la farmacia comunitaria en España debería evolucionar, al igual que ocurre en el resto de los países analizados, hacia un sistema basado en un honorario profesional por las actividades profesionales realizadas, desterrando definitivamente el actual sistema retributivo basado en un margen sobre el precio de venta del medicamento

Spike-based control monitoring and analysis with Address Event Representation
Neuromorphic engineering tries to mimic biological
information processing. Address-Event Representation (AER) is
a neuromorphic communication protocol for spiking neurons
between different chips. We present a new way to drive robotic
platforms using spiking neurons. We have simulated spiking
control models for DC motors, and developed a mobile robot
(Eddie) controlled only by spikes. We apply AER to the robot
control, monitoring and measuring the spike activity inside the
robot. The mobile robot is controlled by the AER-Robot tool,
and the AER information is sent to a PC using the
USBAERmini2 interface.Junta de Andalucía P06-TIC-01417Ministerio de Educación y Ciencia TEC2006-11730-C03-0
An AER-Based Actuator Interface for Controlling an Anthropomorphic Robotic Hand
Bio-Inspired and Neuro-Inspired systems or circuits are a
relatively novel approaches to solve real problems by mimicking the biology
in its efficient solutions. Robotic also tries to mimic the biology and
more particularly the human body structure and efficiency of the muscles,
bones, articulations, etc. Address-Event-Representation (AER) is
a communication protocol for transferring asynchronous events between
VLSI chips, originally developed for neuro-inspired processing systems
(for example, image processing). Such systems may consist of a complicated
hierarchical structure with many chips that transmit data among
them in real time, while performing some processing (for example, convolutions).
The information transmitted is a sequence of spikes coded using
high speed digital buses. These multi-layer and multi-chip AER systems
perform actually not only image processing, but also audio processing,
filtering, learning, locomotion, etc. This paper present an AER interface
for controlling an anthropomorphic robotic hand with a neuro-inspired
system.Unión Europea IST-2001-34124 (CAVIAR)Ministerio de Ciencia y Tecnología TIC-2003-08164-C03-0
Is Sustainable Performance Explained by Firm Effect in Small Business?
To what extent a firm’s resources (firm effect) and the structure of the sector (industry effect) are sources of a firm’s competitiveness has been debated for years in strategic management. Most of the empirical studies carried out have focused on large firms and have used static performance measures, and in them the firm effect generally outweighs the industry effect. This research contributes to this debate in trying to verify whether the competitive advantage that relies on the firm’s resources is sustainable, especially in small firms. We used a sample of almost 15,000 Spanish firms to test the impact that the firm and the industry effects have on sustainable performance, for both small and large firms, applying hierarchical linear modelling with a variable measured through time-varying parameters. Our results confirm the absolute importance of the firm effect on sustainable organizational performance, regardless the firm size, and show that, even though the industry effect has little weight in explaining sustainability, it is significantly higher in the case of small firms. This means that managers must concentrate efforts on providing their firm with the necessary resources to achieve a competitive advantage while choosing a good sector to position itselfS
A Protocol Generator Tool for Automatic In-Vitro HPV Robotic Analysis
Human Papilloma Virus (HPV) could develop precancerous
lesions and invasive cancer, as it is the main cause of nearly all cases
of cervical cancer. There are many strains of HPV and current vaccines
can only protect against some of them. This makes the detection and
genotyping of HPV a research area of utmost importance. Several biomedical
systems can detect HPV in DNA samples; however, most of
them do not have a procedure as fast, automatic or precise as it is actually
needed in this field. This manuscript presents a novel XML-based
hierarchical protocol architecture for biomedical robots to describe each
protocol step and execute it sequentially, along with a robust and automatic
robotic system for HPV DNA detection capable of processing from
1 to 24 samples simultaneously in a fast (from 45 to 162 min), efficient
(100% markers effectiveness) and precise (able to detect 36 different HPV
genotypes) way. It includes an efficient artificial vision process as the last
step of the diagnostic.FIDETIA P055-12/E03Ministerio de Economía y Competitivida TEC2016-77785-
Synthetic retina for AER systems development
Neuromorphic engineering tries to mimic biology in
information processing. Address-Event Representation (AER) is
a neuromorphic communication protocol for spiking neurons
between different layers. AER bio-inspired image sensor are
called “retina”. This kind of sensors measure visual information
not based on frames from real life and generates corresponding
events. In this paper we provide an alternative, based on cheap
FPGA, to this image sensors that takes images provided by an
analog video source (video composite signal), digitalizes it and
generates AER streams for testing purposes.Junta de Andalucía P06-TIC-01417Ministerio de Educación y Ciencia TEC2006-11730-C03-0
Building Blocks for Spikes Signals Processing
Neuromorphic engineers study models and
implementations of systems that mimic neurons behavior in the
brain. Neuro-inspired systems commonly use spikes to
represent information. This representation has several
advantages: its robustness to noise thanks to repetition, its
continuous and analog information representation using digital
pulses, its capacity of pre-processing during transmission time,
... , Furthermore, spikes is an efficient way, found by nature, to
codify, transmit and process information. In this paper we
propose, design, and analyze neuro-inspired building blocks
that can perform spike-based analog filters used in signal
processing. We present a VHDL implementation for FPGA.
Presented building blocks take advantages of the spike rate
coded representation to perform a massively parallel processing
without complex hardware units, like floating point arithmetic
units, or a large memory. Those low requirements of hardware
allow the integration of a high number of blocks inside a FPGA,
allowing to process fully in parallel several spikes coded signals.Junta de Andalucía P06-TIC-O1417Ministerio de Ciencia e Innovación TEC2009-10639-C04-02Ministerio de Ciencia e Innovación TEC2006-11730-C03-0
Automatic selection of the Groebner Basis' monomial order employed for the synthesis of the inverse kinematic model of non-redundant open-chain robotic systems
This is an Author's Accepted Manuscript of an article published in José Guzmán-Giménez, Ángel Valera Fernández, Vicente Mata Amela & Miguel Ángel Díaz-Rodríguez (2023) Automatic selection of the Groebner Basis¿ monomial order employed for the synthesis of the inverse kinematic model of non-redundant open-chain robotic systems, Mechanics Based Design of Structures and Machines, 51:5, 2458-2480, DOI: 10.1080/15397734.2021.1899829 [copyright Taylor & Francis], available online at: http://www.tandfonline.com/10.1080/15397734.2021.1899829[EN] The methods most commonly used to synthesize the Inverse Kinematic Model (IKM) of open-chain robotic systems strongly depend on the robot's geometry, which make them difficult to systematize. In a previous work we presented a systematic procedure that relies on Groebner Bases to synthesize the IKM of non-redundant open-chain robots. This study expands the developed procedure with a methodology for the automatic selection of the basis' monomial order. The procedure's inputs are the robot's Denavit-Hartenberg parameters and the movement range of its actuators, while the output is the synthesized IKM, ready to be used in the robot's control system or in a simulation of its behavior. This procedure can synthesize the IKM of a wide range of open-chain robotic systems, such as Cartesian robots, SCARA, non-redundant multi-legged robots, and all non-redundant manipulators that satisfy the in-line wrist condition. The procedure's performance is assessed through two study cases of open-chain robots: a walking hexapod and a PUMA manipulator. The optimal monomial order is successfully identified for all cases. Also the output errors of the synthesized IKMs are negligible when evaluated in their corresponding workspaces, while their computation times are comparable to those required by the kinematic models calculated by traditional methods.This research was partially funded by Plan Nacional de IthornDthorni, Agencia Estatal de Investigacion del Ministerio de Economia, Industria y Competitividad del Gobierno de Espana, in the project FEDER-CICYT DPI201784201-R.Guzmán-Giménez, J.; Valera Fernández, Á.; Mata Amela, V.; Díaz-Rodríguez, MÁ.
