El papel del modelo económico chaebol en la participación de Corea del Sur en la OCDE

La presente investigación busca dilucidar el papel del modelo económico del chaebol en la participación de Corea del Sur en la Organización para la Cooperación y el Desarrollo Económico OCDE. Las investigaciones en torno al modelo chaebol y sus privilegios en Corea del Sur no han sido enfocadas directamente hacia el ámbito internacional y la influencia que puede tener allí dicho modelo. La investigación busca demostrar que el éxito del modelo económico del chaebol sirvió como incentivo para su entrada y participación activa en la OCDE, consiguiendo de esta forma no solo el establecimiento de una cooperación económica con sus miembros, sino un prestigio y reconocimiento frente a la Comunidad Internacional. Para el desarrollo de esta investigación de tipo cualitativo, se utilizarán fuentes de segundo y tercer grado para llevar a cabo un análisis documental de textos, pertinente para su desarrollo.

Caracterización de las reacciones adversas a medicamentos como causa de ingreso a una unidad de cuidado intermedio en un hospital de tercer nivel de atención

Objetivo: Determinar la ocurrencia de reacciones adversas a medicamentos (RAM) como causa de ingreso a una unidad de cuidado intermedio de un hospital universitario. Materiales y Métodos: Se revisaron las historias clínicas de los pacientes admitidos a la Sala de Emergencias – Cuidado Intermedio (SALEM) entre septiembre y diciembre de 2012 que cumplieron los criterios de inclusión y se detectaron los casos sospechosos de reacción adversa a medicamento (RAM) que posteriormente fueron evaluados por cuatro investigadores respecto a la causalidad a través del Algoritmo de Naranjo, prevenibilidad usando los criterios de Shumock y Thornton y la clasificación clínica mediante el empleo del sistema DoTS. Resultados: Se encontraron 96 pacientes que presentaron 108 casos de RAM. Las RAM más frecuentes fueron las arritmias y la hemorragia de vías digestivas altas (12.04%), 20.3% de los casos correspondieron a fallos terapéuticos, y, los medicamentos mayormente asociados fueron el ácido acetil salicílico (15.74%) y el losartán (10.19%). 46 casos fueron catalogados como posibles y uno solo como definitivo. Usando la clasificación DoTS se estableció que en el 82.4% de los casos la dosis era colateral (dentro del rango de dosis terapéutica), 89.8% fueron independientes del tiempo, y entre los factores mayormente asociados a susceptibilidad a la RAM estuvieron las comorbilidades (41.7%) y la edad (49%). 44% de las RAM fueron prevenibles. Conclusión: Las RAM son una causa de ingreso no despreciable en una unidad de cuidado intermedio para las cuales existen diferentes sistemas de evaluación, y una cantidad significativa de ellas es prevenible. Se requieren más estudios a nivel nacional para evaluar la incidencia de estas y establecer estándares de clasificación y medidas para mitigar su efecto.

La familia del paciente en Unidad de Cuidado Intensivo (UCI)

Introducción: Ingresar a la UCI no es una experiencia exclusiva del paciente; implica e involucra directamente a la familia, en aspectos generadores de estrés, estrategias de afrontamiento, temores, actitudes y expectativas, la participación de la familia en el cuidado y el rol del psicólogo. Objetivo: Revisar de los antecedentes teóricos y empíricos sobre la experiencia de la familia en UCI. Metodología: Se revisaron 62 artículos indexados en bases de datos. Resultados: la UCI es algo desconocido tanto para el paciente como para la familia, por esto este entorno acentúa la aparición de síntomas ansiosos, depresivos y en algunos casos estrés post traumático. La muerte es uno de los principales temores que debe enfrentar la familia. Con el propósito de ajustarse a las demandas de la UCI, los familiares exhiben estrategias de afrontamiento enfocadas principalmente en la comunicación, el soporte espiritual y religioso y la toma de decisiones. El cuidado centrado en la familia permite una mejor comunicación, relación con el paciente y personal médico. El papel del psicólogo es poco explorado en el espacio de la UCI, pero este puede promover estrategias de prevención y de rehabilitación en el paciente y su grupo familiar. Discusión: es importante tener en cuenta que la muerte en UCI es una posibilidad, algunos síntomas como ansiedad, depresión pueden aparecer y mantenerse en el tiempo, centrar el cuidado en la familia permite tomar las decisiones basados en el diagnóstico y pronóstico y promueve expectativas realistas. Conclusiones: temores, expectativas, actitudes, estrategias de afrontamiento, factores generadores de estrés permiten explicar y comprender la experiencia de la familia del paciente en UCI.

A Homogeneous Set-Theoretical Frame for Clustering Fuzzy Relational Data

Our purpose is to provide a set-theoretical frame to clustering fuzzy relational data basically based on cardinality of the fuzzy subsets that represent objects and their complementaries, without applying any crisp property. From this perspective we define a family of fuzzy similarity indexes which includes a set of fuzzy indexes introduced by Tolias et al, and we analyze under which conditions it is defined a fuzzy proximity relation. Following an original idea due to S. Miyamoto we evaluate the similarity between objects and features by means the same mathematical procedure. Joining these concepts and methods we establish an algorithm to clustering fuzzy relational data. Finally, we present an example to make clear all the process

Evasão escolar no ensino fundamental : a concepção de egressos do projovem urbano em Carmópolis/SE : um estudo de caso

A presente pesquisa objetivou, a partir da percepção dos egressos do ProJovem Urbano, do Município de Carmópolis/Sergipe, compreender as razões que levam o aluno à evasão escolar, depois de aderir a um programa educacional. Tendo em atenção o objetivo desse trabalho, que era o de investigar a evasão em programas educacionais, a estratégia de pesquisa selecionada, foi o estudo de caso, exploratório e descritivo, com abordagem qualitativa. A coleta de dados constituiu-se de entrevistas semi estruturadas, realizadas com 20 egressos e 07 professores do programa educacional de governo, ProJovem Urbano, que teve início em abril de 2009 e encerramento em Outubro de 2010, realizado no Município de Carmópolis, Estado de Sergipe/Brasil. Os resultados obtidos permitiram apontar que fatores, enquadrados em três grandes categorias: contexto familiar, contexto social e contexto escolar concorreram para que o estudante interrompesse ou abandonasse sua vida acadêmica. Os dados coletados possibilitaram, também, considerações acerca do conceito de evasão e dos procedimentos utilizados para a investigação desse fenômeno. Buscou-se, em especial, oferecer subsídios para uma reflexão crítica, a respeito dos programas educacionais de governo, criados com o objetivo de facilitar e estimular o ingresso ou o retorno do indivíduo ao ambiente educacional, mas não são suficientes para amenizar as taxas de fracasso ou evasão escolar.

Inclusão no Jardim de Infância : porta para o sucesso da inclusão no 1º ciclo

Este trabalho desenvolve-se no âmbito do mestrado em educação especial, domí-nio cognitivo e motor. Trata-se de um projeto de intervenção emergente do trabalho diário como educadora de infância, num agrupamento vertical de escolas que segue um modelo inclusivo. O projeto centrou-se numa aluna do pré-escolar em vias de ingressar no 1º ciclo e nas estratégias e atividades envolvidas na preparação e sucesso desse ingresso. Nesse sentido tornou-se necessário pesquisar sobre a problemática específica da aluna, sobre práticas inclusivas e sobre métodos e metodologias de intervenção. Isto é, investigou-se sobre paralisia cerebral, escola inclusiva, no modo como se podem articular estas duas questões, sobre pedagogia diferenciada e diferenciação pedagógica e ainda sobre as linhas de orientação para o pré-escolar e sobre as metas a atingir no fim desse ciclo. Desenvolveu-se um processo em que se utilizaram os procedimentos da investiga-ção/ação através de vários instrumentos (pesquisa documental, entrevista, testes sociomé-tricos e observação naturalista) a partir dos quais se elaborou um projeto que foi posto em prática ao longo do ano letivo de 2010/2011. Pode constatar-se no fim da intervenção que os resultados foram positivos, pois permitiram à aluna alcançar os objetivos inicialmente previstos, atingindo as metas da edu-cação pré-escolar e ingressar no 1º ciclo. Foram surgindo novas questões, entre elas a necessidade de promover de forma mais intensa a participação da família e a continuidade do trabalho desenvolvido após uma mudança de ciclo, e portanto, do grupo e dos professores.

The Baltic Museology School : its role in the professional education system

Due to various reasons museum employees from the Baltic States rarely use the chance to study museology abroad. Therefore the State Authority on Museums of Latvia in collaboration with ICOM-Latvia decided to ―deliver‖ this knowledge, by inviting internationally acknowledged lectors from different countries to widen the scope of takers of this opportunity. Estonian and Lithuanian colleagues are also joining in the project, which is included in the cooperation programme of the Ministries of Culture of the Baltic States.

Geometrical isomers of [TEAH][Co(L-Se)(2)]center dot xH(2)O: synthesis, structural, spectroscopic and computational studies

Trans-1, [HNEt3][Co-III(L-Se)(2)]center dot H2O and cis-1, [HNEt3][Co-III(L-Se)(2)]center dot 3H(2)O have been synthesized and characterized by single-crystal X-ray studies. The counter ion Et3NH+ plays a crucial role in the crystal packing leading to the formation of two distinctly different supramolecular assemblies in the two complexes. In trans-1, Co-bisphenolate units and triethylamine molecules are arranged in a linear fashion leading to a supramolecular columnar assembly along the crystallographic a-axis. In this assembly, triethylammonium ions are sandwiched between successive Co-bisphenolate units and act as gluing agents joining Co-bisphenolate units on either side through C-H center dot center dot center dot pi interactions. In sharp contrast to trans-1, Co-bisphenolate units and triethylammonium ions in cis-1 are arranged in a helical supramolecular assembly through similar C-H center dot center dot center dot pi interactions along the crystallographic b-axis. The Se center dot center dot center dot Se van der Waals interactions may be responsible for the predominant occurrence of the cis-isomer. The cyclic voltammetric studies showed quasi-reversible waves for the cobalt(III) -> cobalt(II) reductions with E-1/2 = 0.635 and 0.628 V vs. Ag/AgCl for cis-1 (at similar to 5 degrees C) and trans-1 (at similar to 25 degrees C), respectively. DFT calculations show that the trans-form is the thermodynamic product with higher stability than the cis-one, which is consistent with the variable temperature H-1 NMR studies

Joint modelling of obstacle induced and mesoscale changes: current limits and challenges

Obstacles considerably influence boundary layer processes. Their influences have been included in mesoscale models (MeM) for a long time. Methods used to parameterise obstacle effects in a MeM are summarised in this paper using results of the mesoscale model METRAS as examples. Besides the parameterisation of obstacle influences it is also possible to use a joint modelling approach to describe obstacle induced and mesoscale changes. Three different methods may be used for joint modelling approaches: The first method is a time-slice approach, where steady basic state profiles are used in an obstacle resolving microscale model (MiM, example model MITRAS) and diurnal cycles are derived by joining steady-state MITRAS results. The second joint modelling approach is one-way nesting, where the MeM results are used to initialise the MiM and to drive the boundary values of the MiM dependent on time. The third joint modelling approach is to apply multi-scale models or two-way nesting approaches, which include feedbacks from the MiM to the MeM. The advantages and disadvantages of the different approaches and remaining problems with joint Reynolds-averaged Navier–Stokes modelling approaches are summarised in the paper.

Dielectric relaxation around the nematic-isotropic transition of liquid crystalline polymers

This study is concerned with a series of acrylate based side-chain liquid crystalline (LC) polymers. Previous studies have shown that these LC polymers have a preference for parallel or perpendicular alignment with respect to the polymer chain which depends on the length of the coupling chain joining the mesogenic unit to the polymer backbone. On the other hand, the dielectric relaxation of these side-chain LC polymers shows a strong relaxation associated to the mesogenic unit dynamics. For samples with parallel alignment, it was found that the dielectric relaxation of the nematic is weaker and broader than the relaxation of the isotropic. By contrast, for samples with perpendicular alignment, the isotropic to nematic transition reduces the broadening the relaxation and increases the relaxation strength. These two features are more evident for samples with short coupling units for which the dielectric relaxation observed appears to be strongly coupled with the backbone dynamics.

Symmetry-break in Voronoi tessellations

We analyse in a common framework the properties of the Voronoi tessellations resulting from regular 2D and 3D crystals and those of tessellations generated by Poisson distributions of points, thus joining on symmetry breaking processes and the approach to uniform random distributions of seeds. We perturb crystalline structures in 2D and 3D with a spatial Gaussian noise whose adimensional strength is α and analyse the statistical properties of the cells of the resulting Voronoi tessellations using an ensemble approach. In 2D we consider triangular, square and hexagonal regular lattices, resulting into hexagonal, square and triangular tessellations, respectively. In 3D we consider the simple cubic (SC), body-centred cubic (BCC), and face-centred cubic (FCC) crystals, whose corresponding Voronoi cells are the cube, the truncated octahedron, and the rhombic dodecahedron, respectively. In 2D, for all values α>0, hexagons constitute the most common class of cells. Noise destroys the triangular and square tessellations, which are structurally unstable, as their topological properties are discontinuous in α=0. On the contrary, the honeycomb hexagonal tessellation is topologically stable and, experimentally, all Voronoi cells are hexagonal for small but finite noise with α<0.12. Basically, the same happens in the 3D case, where only the tessellation of the BCC crystal is topologically stable even against noise of small but finite intensity. In both 2D and 3D cases, already for a moderate amount of Gaussian noise (α>0.5), memory of the specific initial unperturbed state is lost, because the statistical properties of the three perturbed regular tessellations are indistinguishable. When α>2, results converge to those of Poisson-Voronoi tessellations. In 2D, while the isoperimetric ratio increases with noise for the perturbed hexagonal tessellation, for the perturbed triangular and square tessellations it is optimised for specific value of noise intensity. The same applies in 3D, where noise degrades the isoperimetric ratio for perturbed FCC and BCC lattices, whereas the opposite holds for perturbed SCC lattices. This allows for formulating a weaker form of the Kelvin conjecture. By analysing jointly the statistical properties of the area and of the volume of the cells, we discover that also the cells shape heavily fluctuates when noise is introduced in the system. In 2D, the geometrical properties of n-sided cells change with α until the Poisson-Voronoi limit is reached for α>2; in this limit the Desch law for perimeters is shown to be not valid and a square root dependence on n is established, which agrees with exact asymptotic results. Anomalous scaling relations are observed between the perimeter and the area in the 2D and between the areas and the volumes of the cells in 3D: except for the hexagonal (2D) and FCC structure (3D), this applies also for infinitesimal noise. In the Poisson-Voronoi limit, the anomalous exponent is about 0.17 in both the 2D and 3D case. A positive anomaly in the scaling indicates that large cells preferentially feature large isoperimetric quotients. As the number of faces is strongly correlated with the sphericity (cells with more faces are bulkier), in 3D it is shown that the anomalous scaling is heavily reduced when we perform power law fits separately on cells with a specific number of faces.

The Climate-G testbed: towards large scale distributed data management for climate change

Climate-G is a large scale distributed testbed devoted to climate change research. It is an unfunded effort started in 2008 and involving a wide community both in Europe and US. The testbed is an interdisciplinary effort involving partners from several institutions and joining expertise in the field of climate change and computational science. Its main goal is to allow scientists carrying out geographical and cross-institutional data discovery, access, analysis, visualization and sharing of climate data. It represents an attempt to address, in a real environment, challenging data and metadata management issues. This paper presents a complete overview about the Climate-G testbed highlighting the most important results that have been achieved since the beginning of this project.

Synthesis, crystal structures and magnetic properties of a phenoxo-bridged dinuclear Cu(II) complex and a dicyanamide bridged novel molecular rectangle based on it

The phenoxo-bridged dinuclear Cu-II complex [Cu2L2-(NCNCN)(2)] (1) and the dicyanamide-bridged molecular rectangle [Cu4L4{mu(1,5)-(NCNCN)(2)}]center dot(ClO4)(2)(H2O)(2) (2) were synthesized using the tridentate reduced Schiff-base ligand HL {2-[(2-dimethylamino-ethylamino) methyl] phenol}. The complexes were characterized by X-ray structural analyses and variable-temperature magnetic susceptibility measurements. Complex 2 was formed through the joining of the phenoxo-bridged dinuclear Cu2O2 cores of 1 via the mu(1,5)-bridging mode of dicyanamide. The structural properties of the Cu2O2 cores in two complexes are significantly different. The geometry of the copper ions is distorted trigonal bipyramid in 1 but is nearly square-pyramidal in 2. These differences have a marked effect on the magnetic properties of two compounds. Although both are antiferromagnetically coupled, the coupling constants (J = -185.2 and -500.9 cm(-1) for 1 and 2, respectively) differ considerably.

Adobe Bickham Script Greek typeface

Design support for typeface design: collaborative work commissioned by Adobe, Inc. Published 2011. The original Bickham typeface was based on the hands of the 18th century writing master George Bickham. The ornate script represented the apogee of the art of formal writing with a steel nib, and defined the visual style for decorated, formal documents. In 2010 Adobe revised and extended the typeface, with the express purpose of making it a showcase for OpenType technology, demonstrating the visual importance of using different glyph forms in different contexts, employing contextual substitution rules. Although Bickham had published a single example of a Greek style, it was a standalone exercise, never intended to match the Latin. The key challenge was to identify historical records for appropriate Greek writing, preferably by writers familiar with the language, adapt them for digital typography and the particularities of contextual substitution, in a manner that would not make the Greek a ‘second-class citizen’. Research involved uncovering and analysing appropriate contemporary and later writing examples to identify both the range of writing styles of the period, and the manner of joining letters in written Greek with both pointed pens and broad nibs. This work was essential to make up for the comparative lack of relevant material by Bickham, as well as investigating the possible range of stylistic variants that were approved for the final typeface, which attempted to emulate a written texture through complex substitutions. This aspect of the work is highly original for implementing a substantial number of contextual alternates and ligatures. These were reviewed in the context of use, bringing together an analysis of occurring letter combinations and patterns, and the design of stylistic alternates to imitate natural handwriting.

The performance effects of composition changes on sector specific stock indices: The case of European listed real estate

This paper examines the impact of changes in the composition of real estate stock indices, considering companies both joining and leaving the indices. Stocks that are newly included not only see a short-term increase in their share price, but trading volumes increase in a permanent fashion following the event. This highlights the importance of indices in not only a benchmarking context but also in enhancing investor awareness and aiding liquidity. By contrast, as anticipated, the share prices of firms removed from indices fall around the time of the index change. The fact that the changes in share prices, either upwards for index inclusions or downwards for deletions, are generally not reversed, would indicate that the movements are not purely due to price pressure, but rather are more consistent with the information content hypothesis. There is no evidence, however, that index changes significantly affect the volatility of price changes or their operating performances as measured by their earnings per share.
