Plan de prevención y atención a la parada cardiorrespiratoria en el Hospital Materno-Infantil de Málaga (Hospital Regional de Málaga)

Sección "Buenas prácticas en gestión clínica"

Plan de mejora para la gestión de los servicios informáticos: ITSM + ITIL v3

El objetivo del presente proyecto es la elaboración de un plan empresarial o conjunto de buenas prácticas, el cual pueda ser utilizado como guía para la mejora de servicios por una organización TIC. La implantación y puesta en valor de dicho conjunto de buenas prácticas nos va a permitir mejorar la calidad en aspectos relativos en cuanto a la gestión de servicios se refiere.

Study and implementation of some quantitative trading models

Quantitative or algorithmic trading is the automatization of investments decisions obeying a fixed or dynamic sets of rules to determine trading orders. It has increasingly made its way up to 70% of the trading volume of one of the biggest financial markets such as the New York Stock Exchange (NYSE). However, there is not a signi cant amount of academic literature devoted to it due to the private nature of investment banks and hedge funds. This projects aims to review the literature and discuss the models available in a subject that publications are scarce and infrequently. We review the basic and fundamental mathematical concepts needed for modeling financial markets such as: stochastic processes, stochastic integration and basic models for prices and spreads dynamics necessary for building quantitative strategies. We also contrast these models with real market data with minutely sampling frequency from the Dow Jones Industrial Average (DJIA). Quantitative strategies try to exploit two types of behavior: trend following or mean reversion. The former is grouped in the so-called technical models and the later in the so-called pairs trading. Technical models have been discarded by financial theoreticians but we show that they can be properly cast into a well defined scientific predictor if the signal generated by them pass the test of being a Markov time. That is, we can tell if the signal has occurred or not by examining the information up to the current time; or more technically, if the event is F_t-measurable. On the other hand the concept of pairs trading or market neutral strategy is fairly simple. However it can be cast in a variety of mathematical models ranging from a method based on a simple euclidean distance, in a co-integration framework or involving stochastic differential equations such as the well-known Ornstein-Uhlenbeck mean reversal ODE and its variations. A model for forecasting any economic or financial magnitude could be properly defined with scientific rigor but it could also lack of any economical value and be considered useless from a practical point of view. This is why this project could not be complete without a backtesting of the mentioned strategies. Conducting a useful and realistic backtesting is by no means a trivial exercise since the \laws" that govern financial markets are constantly evolving in time. This is the reason because we make emphasis in the calibration process of the strategies' parameters to adapt the given market conditions. We find out that the parameters from technical models are more volatile than their counterpart form market neutral strategies and calibration must be done in a high-frequency sampling manner to constantly track the currently market situation. As a whole, the goal of this project is to provide an overview of a quantitative approach to investment reviewing basic strategies and illustrating them by means of a back-testing with real financial market data. The sources of the data used in this project are Bloomberg for intraday time series and Yahoo! for daily prices. All numeric computations and graphics used and shown in this project were implemented in MATLAB^R scratch from scratch as a part of this thesis. No other mathematical or statistical software was used.

Participación social en salud: conceptos de usuarios, líderes comunitarios, gestores y formuladores de políticas en Colombia. Una mirada cualitativa.

BACKGROUND Health sector reforms taking place in Colombia during the Nineties included policies to promote social participation in the health system, which is considered essential to its functioning. The aim of this article is to analyse the meaning and the significance of participation in health for the different social actors involved in implementing policies in Colombia. METHODS A qualitative, descriptive, exploratory study was carried out using focal groups (FG) and semi-structured individual interviews (I) of the different social actors: 210 users (FG), 40 community leaders (FG), 3 policy makers (E) and 36 healthcare professionals (E). A carried out analysis was content up of the contents. The study area corresponded to the municipalities of Tulua and Palmira in Colombia. RESULTS The concept of participation was interpreted differently depending on the actor studied: for users and leaders the concept referred to contributing ideas, presence in social spaces, solidarity and frequently, and use of the health services. Healthcare professionals considered the activities carried out by institutions together with the community as social participation, the use of services and affiliation to the health system. Policy markers considered participation to concern evaluation and control of the health services by the community, to improve its quality. CONCLUSIONS The different concepts of participation reveal dif ferences between the content of the policy and how it is understood and interpreted by the different social actors in their interaction with the health services. These different perspectives must be taken into account to develop a link between society and the health services.

Implementation of zonal control algorithms in adaptive optical systems with sparse control matrices

Miralls deformables més i més grans, amb cada cop més actuadors estan sent utilitzats actualment en aplicacions d'òptica adaptativa. El control dels miralls amb centenars d'actuadors és un tema de gran interès, ja que les tècniques de control clàssiques basades en la seudoinversa de la matriu de control del sistema es tornen massa lentes quan es tracta de matrius de dimensions tan grans. En aquesta tesi doctoral es proposa un mètode per l'acceleració i la paral.lelitzacó dels algoritmes de control d'aquests miralls, a través de l'aplicació d'una tècnica de control basada en la reducció a zero del components més petits de la matriu de control (sparsification), seguida de l'optimització de l'ordenació dels accionadors de comandament atenent d'acord a la forma de la matriu, i finalment de la seva posterior divisió en petits blocs tridiagonals. Aquests blocs són molt més petits i més fàcils de fer servir en els càlculs, el que permet velocitats de càlcul molt superiors per l'eliminació dels components nuls en la matriu de control. A més, aquest enfocament permet la paral.lelització del càlcul, donant una com0onent de velocitat addicional al sistema. Fins i tot sense paral. lelització, s'ha obtingut un augment de gairebé un 40% de la velocitat de convergència dels miralls amb només 37 actuadors, mitjançant la tècnica proposada. Per validar això, s'ha implementat un muntatge experimental nou complet , que inclou un modulador de fase programable per a la generació de turbulència mitjançant pantalles de fase, i s'ha desenvolupat un model complert del bucle de control per investigar el rendiment de l'algorisme proposat. Els resultats, tant en la simulació com experimentalment, mostren l'equivalència total en els valors de desviació després de la compensació dels diferents tipus d'aberracions per als diferents algoritmes utilitzats, encara que el mètode proposat aquí permet una càrrega computacional molt menor. El procediment s'espera que sigui molt exitós quan s'aplica a miralls molt grans.
