Patient satisfaction′s level with the nursing activities timetable.
Laura Carretero Cortes,Silvia Vicente Orgaz,Elena Sofía Palacios Arribas
NURE Investigación , 2011,
Abstract: The assessment of patient satisfaction allows one the one hand to identify deficient areas from the point of view of the patient and on the other hand to evaluate the care outcomes.Patient′s opinion is an essential component in the assessment of the service. If patients are dissatisfied, care is far away from what it should be, no matter how high quality can be assesed through clinical indicators.The objective was to determine the patient satisfaction′s level with the schedule established in the hospital. Thus, a descriptive study that using simple random sampling the elements of the random sample were chosen directly in one step, assign each person hospitalized in a hospital in Toledo BZH a number and through a mechanical means (balls in a bag) we get random items that will be part of the sample (50 patients in the Hospital of Toledo BZH), so that each element in the population had an equal chance of being selected. The survey provides a closed, compilation, anonymous and voluntary.Results points to a certain degree of dissatisfaction among users, strict schedules and adapted to the "rotation" of health personnel, not patients.Analyzing the results in the development of activity schedules nursing activities: hygiene, feeding, etc ... we can see a big difference being a high percentage of patients who would prefer to change some schedules.
Densification and crystalization kinetics of mullite diphasic gels from non_isothermal dilatometry experiments
Orgaz, Felipe
Boletín de la Sociedad Espa?ola de Cerámica y Vidrio , 2008,
Abstract: Mullite (3 AI2O3_2 SiO2) was processed by mixing silica and alumina colloids at pH below 3 in a high shear blender. The gels were sieved to 125 microns and cold isostatically pressed to form rods. The various processes involved during the sintering process such as condensation-polymerization and the competition between mullite crystallization and densification were analysed from constant heating rate equations and rate controlled sintering dilatometer experiments. Changes in the slopes permitted the identification of such processes and the activation energy for mullitization was calculated. Fast firing (20-30 K/min) in the critical mullitization temperature range of 1230-1505oC and low heating rates (2-3 K/min) in the viscous flow densification intervals of below 1230oC and higher than 1505 gives rise to near full density and fine grain microstructures of sintered mullite. Fast firing and high (0.5 to 1 % /min) densification rate controlled processes seem to be the most suitable approaches to high density gel processed mullite. Amorphous silica is the rate controlling mechanism for the viscous flow densification process before alumina is solved and nucleation and crystallization of mullite appears. Deviations from the linear Frenkel model for viscous flow are also observed. Mullita de composición (3Al2O3 -2 SiO2) ha sido preparada mezclando coloides de sílice y alúmina en un mezclador de alta velocidad a pH inferior a 3. Los geles formados eran secados, tamizados por debajo de 125 micras y prensados isostáticamrente para formar varillas de unos 6 mm de diámetro. Los diferentes procesos que ocurren durante el proceso de sinterización, tales como polimerización- condensación y la competición entre cristalización y densificación, han sido analizados utilizando las ecuaciones de ecuaciones de velocidad de calentamiento constantte y experimentos de dilatometría utilizando un software que permite realizar ensayos a velocidad de contracción constante. Cambios en las pendientes han permitido la identificación de tales procesos y el calculo de la energia de activación para la formación de mullita. Calentamiento rápido (20-30 K/min) en el rango critico de formación de mullita entre 1230-1505oC y bajas velocidades de calentamiento (2-3 K/min) en las zonas de densificación por flujo viscoso daban lugar a mullitas sinterizadas con densidad cercana a la teórica y fina micro-estructura. Altas velocidades de densificación (o,5% a 1%/min) son las mas adecuadas para sinterizar mullita de alta densidad. Flujo viscoso de la sílice amorfa es el mecanismo que controla la v
Mercado de trabajo y formación entre inmigrantes latinoamericanos en la Comunidad de Madrid
Rodríguez, Vicente,Marcu, Silvia
Revista de Indias , 2009,
Abstract: This paper analyses the relation between training and employment in the Community of Madrid (CAM) of immigrants from Ecuador and Colombia. The first part of the paper deals with the imbalance between training and employment, stressing the immigrants’ level of training in their countries of origin, whereas the second part analyses the need and value of training in order to have access to labour market in Madrid. By analysing the discourse of immigrants and specialists in this field (via thorough interviews and focus groups), it is possible to go further into the discussion about the present situation and prospects of labour market and immigration, on the one hand, and, on the other hand, about the challenges and limitations of socio-labour intervention as a means to the integration of the Latin American community. El artículo estudia la relación existente entre la formación y el empleo inmigrante en la Comunidad de Madrid (CAM), de los inmigrantes procedentes de Ecuador y Colombia. La primera parte aborda los desajustes existentes entre la formación y el empleo haciendo hincapié en el nivel formativo de los inmigrantes en los países de origen, mientras que la segunda parte analiza la necesidad y el valor de la formación para el acceso laboral en el mercado de trabajo madrile o. A partir del análisis del discurso de los inmigrantes y de los técnicos especialistas en el ámbito (entrevistas en profundidad y grupos focales), es posible avanzar en el debate acerca del presente y de las perspectivas de futuro del mercado de trabajo y la inmigración, por una parte, y de los retos y limitaciones de la intervención sociolaboral como vía para la integración del colectivo latinoamericano, por la otra parte.

Psicología desde el Caribe , 2000,
Abstract: Los trastornos de personalidad representan hoy día una de las áreas de mayor desafío para la psicología científica. Aunque los principales sistemas de clasificación de la psicopatología (DSM-IV y CIE-10) les dedican un considerable espacio, son, quizás, unos de los grupos de síndromes más desconocidos a todos los niveles: epidemiología, etiología, evaluación, tratamiento, etc. En el breve trabajo que aquí presentamos intentamos describir brevemente diversos aspectos de uno de los trastornos de personalidad más representativos actualmente: el trastorno límite de la personalidad (TLP). A pesar de que este síndrome comparte con el resto de los trastornos de personalidad una escasez de conocimiento, es, probablemente, uno de los más investigados y sobre el que se han desarrollado una variedad de terapias cognitivo-conductuales. A lo largo de este trabajo planteamos también algunas de las controversias actuales más candentes y resaltamos la necesidad de una mayor y más sistematizada investigación sobre el TLP.
Achalasia: un trastorno de la motilidad esofágica, no tan raro
Orgaz Gallego,Ma Pilar;
Revista Clínica de Medicina de Familia , 2009, DOI: 10.4321/S1699-695X2009000100010
Abstract: achalasia is a rare motility disorder of the distal esophagus, of unknown etiology. the irreversible destruction of esophageal myenteric plexus neurons is causes aperistalsis and the failure of lower esophageal sphincter to relaxduring deglutition. consequently, the food bolus stops at the level of the cardia producing disphagia and others symptoms such as regurgitation, chest pain, heartburn and weight loss. with a thorough medical history, upper gi endoscopy and barium swallow x-ray a diagnosis of achalasia can be suspected and later confirmed by esophagueal manometry. others diseases, especially malignant diseases, can imitate the clinical symptoms. pneumatic balloon dilatation is the first choice treatment for achalasia, but heller myiotomy is now becoming the treatment of choice in many hospitals because it is significantly less invasive and costly. heller myotomy together with laparoscopic fundoplication in order to prevent reflux should be offered when dilatation therapy fails, especially in younger patients. i present two cases of achalasia, demonstrating that, although the incidence is approximately 1 per 100,.000 people per year, it is not so infrequent in clinical practice as one would think.
El uso de los tests genéticos por parte de las compa ías de seguros

Ciencia Ergo Sum , 2011,
Abstract: Se aborda la discusión en torno a la pertinencia del uso de tests genéticos por parte de las compa ías de seguros. La idea que se defiende es la siguiente: si decidimos regular el recurso a los tests genéticos fuera del ámbito sanitario, que sea para hacer justicia a los derechos de terceras personas y en ningún caso por miedo a posibles discriminaciones. Se trata de llamar la atención sobre los riesgos aparejados al uso irresponsable de los datos genéticos por parte de las compa ías de seguros, y se llega a la conclusión de que un uso tal compromete los derechos de terceras personas implicadas. Por último, plantearemos posibles escenarios para el futuro sobre el procesamiento de la información genética

Abstract: oral tradition is an important mechanism for transmission of knowledge and belief in prehistoric societies where memory has an outstanding role. different investigations carried out in the andean region have demonstrated that diverse cultural practices are maintained through social memory. we present and discusses the results from a neutron activation analysis of potsherds and clay deposits which demonstrate that clay raw material from la troya, located at the bolsón de fiambalá, was used for the manufacture of ceramic artifacts. these artifacts supplied puna instalations as well as others at the abaucán basin (tinogasta department, catamarca, argentina) from the formative epoch to the inka arrival in the region. based on these results, we think that exploitation and appropriation of the same clay for a long period of time is not fortuitous, but rather is the consequence of a long process of social memory reproduction

Abstract: La oralidad es el mecanismo principal de transmisión de conocimientos y creencias en las sociedades tradicionales donde la memoria cumple un papel destacado. Diferentes investigaciones llevadas a cabo en la región de los Andes demostraron que diversas prácticas culturales son mantenidas a través de la memoria social. En este trabajo se presentan y discuten los resultados del análisis por activación neutrónica realizados sobre tiestos y depósitos arcillosos, los que establecen que el alfar de La Troya, localizado en el Bolsón de Fiambalá, fue explotado para la manufactura de artefactos cerámicos que abastecieron a las instalaciones pune as y otras localizadas en la amplia cuenca del Abaucán (Departamento Tinogasta, Catamarca, Argentina) desde las sociedades Formativas hasta el arribo de los Inkas a la región. Con base en esos resultados pensamos que la explotación y apropiación en el tiempo de un mismo alfar no es casualidad sino que obedece a la memoria que reproduce la práctica social en el tiempo. Asimismo, evaluamos los datos arqueológicos y analíticos obtenidos para comprender el proceso propio de desarrollo cultural del valle de Abaucán y su relación con el área pune a meridional Oral tradition is an important mechanism for transmission of knowledge and belief in prehistoric societies where memory has an outstanding role.

Abstract: The unexpected tendency of amines and functionalized hydrazines to reduceethyl 3-phenylquinoxaline-2-carboxylate 1,4-di-N-oxide (1) to afford a quinoxaline 1c andmono-oxide quinoxalines 1a and 1b is described. The experimental conditions werestandardized to the use of two equivalents of amine in ethanol under reflux for two hours,with the aim of studying the distinct reductive profiles of the amines and thechemoselectivity of the process. With the exception of hydrazine hydrate, which reducedcompound 1 to a 3-phenyl-2-quinoxalinecarbohydrazide derivative, the amines only actedas reducing agents.
