Die emotionale Zufriedenheit von Patienten mit der anästhesiologischen Betreuung
2003
Objective The evaluation of services by patients is an integral part of continuous quality improvement in anaesthesia. Patient satisfaction is affected by various objective and subjective variables. Individual experiences, impressions and needs represent an important part of overall patient satisfaction. Methods Data of 519 patients were collected in a standardised anonymous questionnaire independent of the post-anaesthetic visit. Results Anaesthesia staff appeared to be friendly to 97 % of patients asked, 95 % of patients wanted to be treated by the same staff in case of another anaesthesia, nearly 87 % felt relaxed and satisfied after anaesthesia. Up to 26 % of patients felt tense after p…
Preliminary prediction model for identifying patients with the possibility of pharmacotherapy improvement
2010
Abstract Objective To develop a prediction model for identifying patients with the possibility of improving pharmacotherapy during the process of pharmaceutical validation of the prescription. Method Cross-sectional study over two months, performed in the Internal Medicine and Infectious Disease divisions. Detecting opportunities for improving quality of pharmacotherapy is done by means of a pharmacist's validation of the prescription. Based on the information we obtained through this process, we performed a multivariate logistic regression analysis using as prognostic factors the demographic, pharmacotherapy and clinical variables related to identifying any drug-related problems (DRPs) in …
Clinical retrospective study of dental implant removal : do patients who require implant removal desire implant prosthesis again?
2020
Background This study investigated the causes of dental implant removal due to complications, and examined whether patients who had dental implant removal desired re-implant prosthesis treatments. Material and Methods A retrospective case–control study was conducted on patients who had their dental implants removed. We investigated whether the removed dental implant was replaced with other implant prostheses. Age, sex, diabetes, smoking, implant site distribution, reason for implant removal, and blade and root-form implants were categorized as predictive variables. The outcome variable was desire for re-implantation or use of other prosthetic methods after implant removal. A logistic regres…
Uniformization of two-dimensional metric surfaces
2014
We establish uniformization results for metric spaces that are homeomorphic to the Euclidean plane or sphere and have locally finite Hausdorff 2-measure. Applying the geometric definition of quasiconformality, we give a necessary and sufficient condition for such spaces to be QC equivalent to the Euclidean plane, disk, or sphere. Moreover, we show that if such a QC parametrization exists, then the dilatation can be bounded by 2. As an application, we show that the Euclidean upper bound for measures of balls is a sufficient condition for the existence of a 2-QC parametrization. This result gives a new approach to the Bonk-Kleiner theorem on parametrizations of Ahlfors 2-regular spheres by qu…
Motivación y aprendizaje escolar en la Educación Secundaria Obligatoria: Un estudio empírico desde el Modelo de Calidad de Situación Educativa
2015
La desmotivación de los alumnos/as es uno de los principales problemas con los que se enfrenta actualmente el profesorado, sobre todo en los niveles de educación secundaria. Basándonos en el Modelo de Calidad de Situación Educativa (MCSE) (Doménech, 2006, 2007, 2011a, 2011b, 2012, 2013 y Doménech-Betoret, Gómez-Artiga y Lloret-Segura, 2014), este estudio, compuesto de cuatro investigaciones independientes, examina a) cómo se genera la motivación de los alumnos/as de secundaria y cómo ésta va evolucionando a lo largo del curso en función de sus variables personales y de la percepción que éstos se formen del contexto de la situación educativa. Además, b) examina de forma simultánea el efecto …
Interactions, spillovers de connaissance et croissance des économies modernes. Faut-il préférer la globalisation ou la proximité géographique ?
2009
Globalisation and metropolisation in modern economies induce some locational strategies of knowledge based activities towards cities and deeply increase trade and move of ideas across cities. In that context, we study the way knowledge spillovers have influenced the economic growth of 82 European Metropolises over the 1990-2005 period. We model knowledge spillovers across cities according to three specific interaction patterns depending either on geography or on global advanced services or thought a combination of these patterns. We show that the mixed pattern matters the best for economic growth of cities in Europe.
MULTICRITERIA ANALYSIS – INSTRUMENT FOR AN ACCURATE ANALYSIS OF THE IMPACT OF THE SERVICE SECTOR ON THE ECONOMY
2013
The current paper represents an attempt to introduce multicriteria analysis as an efficient instrument to prove that the development of services in Romania has a major impact on all aspects of our economy and represents the right path to pursue in terms of economic growth, on a medium and long term basis.The paper presents a general approach to multicriteria analysis as a means to successfully reveal the impact of the service sector on the economy of Romania. Several advantages as well as limits are presented, along with a brief presentation of the concept of composite synergy of services, corollary of the multicriteria analysis.
Explotación sinérgica de datos multiespectrales y radar para la estimación de variables biofísicas de la vegetación mediante tecnologías de sensorami…
2023
Las variables biofísicas de la vegetación (VBV) son indicadores directos del crecimiento y productividad de los cultivos. Los sistemas de observación de la Tierra (EO–Earth observation) presentan oportunidades sin precedentes para el monitoreo de las variables biofísicas del trigo. Sentinel–2 (S2) es una constelación de satélites que forma parte de las misiones Sentinel del programa Copernicus de EO. El período de revisita, así como su resolución espacial y espectral, han convertido a S2 en un sistema de EO trascendental para el monitoreo de VBV. Los sistemas ópticos de EO se ven limitados con frecuencia por las condiciones climáticas tales como nubosidad o precipitaciones. En este sentido,…
STUDIES OF VARIABILITY IN PROTO-PLANETARY NEBULAE. II. LIGHT AND VELOCITY CURVE ANALYSES OF IRAS 22272+5435 AND 22223+4327
2013
We have carried out a detailed observational study of the light, color, and velocity variations of two bright, carbon-rich proto-planetary nebulae, IRAS 22223+4327 and 22272+5435. The light curves are based upon our observations from 1994 to 2011, together with published data by Arkhipova and collaborators. They each display four significant periods, with primary periods for IRAS 22223+4327 and 22272+5435 being 90 and 132 days, respectively. For each of them, the ratio of secondary to primary period is 0.95, a value much different from that found in Cepheids, but which may be characteristic of post-asymptotic giant branch (AGB) stars. Fewer significant periods are found in the smaller radia…
Human capital and the intertemporal substitution for leisure: empirical evidence for Spain
2022
AbstractIn this paper we provide the first estimate of the intertemporal substitution for leisure in Spain, accounting for the impact of human capital accumulation. This would allow uncovering whether the intertemporal labour supply of Spanish workers is affected by human capital. Our empirical strategy consists of estimating the equation for the intertemporal substitution of leisure with and without accounting for human capital, what allows to detect hypothetical estimation biases associated to omitting the impact of human capital. To that end, we build a pseudo-panel data set combining the Spanish Family Expenditure Survey and the Labour Survey over the period 1987–1997. While the model t…
