La integració conceptual o blending i l’arc de Sant Martí: vers una semàntica cognitiva diacrònica i cultural

Aquest article fa un estudi onomasiològic de les denominacions de l’arc de Sant Martí en una perspectiva diacrònica, de contacte de llengües (català, occità, aragonès, etc.) i segons la teoria de la integració conceptual o blending. Planteja la necessitat que la semàntica diacrònica cognitiva faça pròpia l’orientació cultural (fonamentalment, antropològica, històrica social i cultural) i semiòtica.

La aprehensión cognitiva en problemas de generalización de patrones lineales

El objetivo del estudio es examinar qué tipo de aprehensiones cognitivas utilizan alumnos de Educación Primaria cuando resuelven problemas de generalización lineal. 81 alumnos de 5º y 6º curso resolvieron dos problemas de generalización lineal que diferían en la configuración de la sucesión de figuras dadas (mesas cuadradas o mesas en forma de trapecio). Los resultados indican que la configuración de la sucesión de figuras condiciona el tipo de aprehensión utilizada por los alumnos; en algunos casos tienen dificultades para cambiar de aprehensión.

Promoção da saúde e funcionalidade em idosos com incapacidade cognitiva institucionalizados

A funcionalidade e a independência, factores preponderantes para o diagnóstico da saúde física e mental da pessoa idosa, são ameaçadas quando surge incapacidade física ou cognitiva que dificulte a realização das tarefas do dia-a-dia. Em situação de institucionalização, o auxílio ou a substituição na realização das AVDs geralmente potencia a imobilidade e a dependência do idoso. A actividade física, e concretamente o treino funcional, está associada a melhorias significativas no grau de dependência em idosos. Na promoção de programas de actividade física para indivíduos com distúrbios cognitivos, estratégias de comunicação verbal e não verbal, e de memorização provaram ser efectivas na facilitação da aprendizagem e na mudança de comportamentos. Assim, implementou-se um programa de actividade física em que participaram 13 utentes idosos com incapacidade cognitiva, institucionalizados numa valência de saúde mental, com o objectivo principal de maximizar a sua funcionalidade, através do treino funcional, e com recurso a estratégias comportamentais de comunicação e memorização. O estudo incluiu também um grupo de controlo constituído por 11 utentes. As sessões tiveram a duração de 30 minutos, e decorreram 2 vezes por semana, durante 12 semanas. Os resultados foram avaliados através dos seguintes indicadores: grau de dependência funcional (índice de Barthel), equilíbrio (teste Timed Up and Go), força de preensão (teste de força de preensão), velocidade da marcha (teste de marcha dos 10 metros). Foram efectuados três momentos de avaliação: antes do início da intervenção, ao final de 6 semanas e no final das 12 semanas de programa. Após a análise dos resultados, concluiu-se que este programa mostrou ser efectivo nos objectivos a que se propõe e exequível nesta população. No entanto, foram identificadas algumas limitações que deverão merecer atenção numa futura implementação.

UMA NOVA CARTOGRAFIA COGNITIVA PARA O ENSINO DA COMUNICAÇÃO

O trabalho proposto é a montar um projeto exploratório funcional que parta da cartografia cognitiva, que é definida como a arte, teoria e técnica de construir mapas do conhecimento, visando com esta cartografia a sua aplicabilidade na estruturação de um conjunto de cursos/saberes da área da Comunicação. Assemelhado ao conceito de mapas conceituais, ou cognitivos, representam o conhecimento organizado e são compostos por conceitos. Este mapas foram desenvolvido a partir da década de setenta por vários pesquisadores. A tese experimento foi montada tendo como base os softwares de relacionamento por temas e interesses dentro de um ambiente de interatividade tridimensional , montado no conceito de arvore do conhecimento relacional. Esta experiência é construída em ambiente tridimensional com uso de softwares 3D que rodam como aplicativos de engines de vídeo games, que são motores gráficos. A base de dados e a interatividade de textos e tarefas é realizada sob a plataforma do MediaWiki, que é o software aberto que roda a Wikipédia. A plataforma de mapas roda dentro de um software MindJet MindManager e do CMAPS. As vídeo conferências são administradas pelo FlashMeeting, de Web conferência. A maioria deles são softwares abertos. Todos operando em sistemas presenciais ou de modulação EAD. A base conceitual está estruturada dentro de uma visão de educação disruptiva, que lança um novo modelo educacional baseado em mapas, visto dentro de uma abordagem de um mundo de múltiplas telas, um mundo da era hiper, um mundo hipermoderno, que tem como base uma cultura da era tecnológica, numa renovação dos conceitos de Cultura, agora revigorados à luz das novas tecnologias e da nova sociedade interligada em rede.

A figuratividade nas histórias em quadrinhos: uma análise das construções metafóricas e metonímicas em V de vingança

The object of this study is the construction of metaphor and metonymy in comics. This work is inserted in the field of Embodied Cognitive Linguistics, specifically based on the Neural Theory of Language (FELDMAN, 2006) and, consistent with this theoretical and methodological framework, the notions of categorization (LAKOFF & JOHNSON, 1999), embodiment (GIBBS, 2005), figurativity (GIBBS, 1994; BERGEN, 2005), and mental simulation (BARSALOU, 1999; FELDMAN, 2006) have also been used. The hypothesis defended is that the construction of figurativity in texts consisting of verbal and nonverbal mechanisms is linked to the activation of neural structures related to our actions and perceptions. Thus, language is considered a cognitive faculty connected to the brain apparatus and to bodily experiences, in such a way that it provides samples of the continuous process of meaning (re)construction performed by the reader, whom (re)defines his or her views about the world as certain neural networks are (or stop being) activated during linguistic processing. The data obtained during the analysys shows that, as regards comics, the act of reading together the graphics and verbal language seems to have an important role in the construction of figurativity, including cases of metaphors which are metonymically motivated. These preliminary conclusions were drawn from the data analysis taken from V de Vingança (MOORE; LLOYD, 2006). The corpus study was guided by the methodology of introspection, i.e., the individual analysis of linguistic aspects as manifested in one's own cognition (TALMY, 2005).

Processos de construção do sentido por portadores da Síndrome de Asperger

Para la lingüística Cognitiva, la construcción del sentido darse a través del accionamiento de procesos mentales específicos que están directamente ligados a las experiencias socioculturales, sensorio motores y perceptuales. En portadores de la Síndrome de Asperger, el comprometimiento de estos procesos, debido a características específicas dela propia síndrome, puede estar directamente relacionado a problemas de construcción de sentido por estos individuos. En este sentido, el objetivo de esta investigación es investigar los procesos cognitivos que direccionan la construcción del sentido en estos portadores de trastornos neurales. La investigación es realizada con alumnos de la APPARN (Associação de país e amigos dos autistas do Rio Grande do Norte), teniendo como grupo de control alumnos neurotípicos de otras instituciones, siendo los portadores de la síndrome practicantes de la lengua materna o grupo experimental de la búsqueda. Para elucidar el proceso de construcción del sentido por estos alumno, fueron desarrollados testes contiendo rasgos linguisticos norteadores responsables por el accionamiento de algunos procesos cognitivos como los esquemas (JOHNSON, 1987), frames (MINSKY, 1974), affordances (GIBSON, 1979) y simulación mental (BARSALOU, 1999). Los testes fueron basados en los presupuestos teóricos de la Lingüística Cognitiva, más precisamente, de la Teoria Neural del Linguaje. Los resultados apuntan para una posible justificativa para el comprometimiento de la construcción del sentido en portadores de la Síndrome de Asperger, que comprende directamente la relevancia intersubjetiva de la infersencias recibidas y construidas socialmente por los participantes específicamente de este análisis.

A simulação realística como estratégica de ensino-aprendizagem em enfermagem

The study aims to examine the methodology of realistic simulation as facilitator of the teaching-learning process in nursing, and is justified by the possibility to propose conditions that envisage improvements in the training process with a view to assess the impacts attributed to new teaching strategies and learning in the formative areas of health and nursing. Descriptive study with quantitative and qualitative approach, as action research, and focus on teaching from the realistic simulation of Nursing in Primary Care in an institution of public higher education. . The research was developed in the Comprehensive Care Health discipline II, this is offered in the third year of the course in order to prepare the nursing student to the stage of Primary Health Care The study population comprised 40 subjects: 37 students and 3 teachers of that discipline. Data collection was held from February to May 2014 and was performed by using questionnaires and semi structured interviews. To do so, we followed the following sequence: identification of the use of simulation in the discipline target of intervention; consultation with professors about the possibility of implementing the survey; investigation of the syllabus of discipline, objectives, skills and abilities; preparing the plan for the execution of the intervention; preparing the checklist for skills training; construction and execution of simulation scenarios and evaluation of scenarios. Quantitative data were analyzed using simple descriptive statistics, percentage, and qualitative data through collective subject discourse. A high fidelity simulation was inserted in the curriculum of the course of the research object, based on the use of standard patient. Three cases were created and executed. In the students’ view, the simulation contributed to the synthesis of the contents worked at Integral Health Care II discipline (100%), scoring between 8 and 10 (100%) to executed scenarios. In addition, the simulation has generated a considerable percentage of high expectations for the activities of the discipline (70.27%) and is also shown as a strategy for generating student satisfaction (97.30%). Of the 97.30% that claimed to be quite satisfied with the activities proposed by the academic discipline of Integral Health Care II, 94.59% of the sample indicated the simulation as a determinant factor for the allocation of such gratification. Regarding the students' perception about the strategy of simulation, the most prominent category was the possibility of prior experience of practice (23.91%). The nervousness was one of the most cited negative aspects from the experience in simulated scenarios (50.0%). The most representative positive point (63.89%) pervades the idea of approximation with the reality of Primary Care. In addition, professors of the discipline, totaling 3, were trained in the methodology of the simulation. The study highlighted the contribution of realistic simulation in the context of teaching and learning in nursing and highlighted this strategy while mechanism to generate expectation and satisfaction among undergraduate nursing students

Estudo das forças capilar, viscosa e gravitacional através de grupos adimensionais na simulação da drenagem gravitacional assistida por gás (GAGD)

The distribution and mobilization of fluid in a porous medium depend on the capillary, gravity, and viscous forces. In oil field, the processes of enhanced oil recovery involve change and importance of these forces to increase the oil recovery factor. In the case of gas assisted gravity drainage (GAGD) process is important to understand the physical mechanisms to mobilize oil through the interaction of these forces. For this reason, several authors have developed physical models in laboratory and core floods of GAGD to study the performance of these forces through dimensionless groups. These models showed conclusive results. However, numerical simulation models have not been used for this type of study. Therefore, the objective of this work is to study the performance of capillary, viscous and gravity forces on GAGD process and its influence on the oil recovery factor through a 2D numerical simulation model. To analyze the interplay of these forces, dimensionless groups reported in the literature have been used such as Capillary Number (Nc), Bond number (Nb) and Gravity Number (Ng). This was done to determine the effectiveness of each force related to the other one. A comparison of the results obtained from the numerical simulation was also carried out with the results reported in the literature. The results showed that before breakthrough time, the lower is the injection flow rate, oil recovery is increased by capillary force, and after breakthrough time, the higher is the injection flow rate, oil recovery is increased by gravity force. A good relationship was found between the results obtained in this research with those published in the literature. The simulation results indicated that before the gas breakthrough, higher oil recoveries were obtained at lower Nc and Nb and, after the gas breakthrough, higher oil recoveries were obtained at lower Ng. The numerical models are consistent with the reported results in the literature

Modelagem e simulação da solubilidade de sais em sistemas aquosos com Monoetilenoglicol

Primary processing of natural gas platforms as Mexilhão Field (PMXL-1 ) in the Santos Basin, where monoethylene glycol (MEG) has been used to inhibit the formation of hydrates, present operational problems caused by salt scale in the recovery unit of MEG. Bibliographic search and data analysis of salt solubility in mixed solvents, namely water and MEG, indicate that experimental reports are available to a relatively restricted number of ionic species present in the produced water, such as NaCl and KCl. The aim of this study was to develop a method for calculating of salt solubilities in mixed solvent mixtures, in explantion, NaCl or KCl in aqueous mixtures of MEG. The method of calculating extend the Pitzer model, with the approach Lorimer, for aqueous systems containing a salt and another solvent (MEG). Python language in the Integrated Development Environment (IDE) Eclipse was used in the creation of the computational applications. The results indicate the feasibility of the proposed calculation method for a systematic series of salt (NaCl or KCl) solubility data in aqueous mixtures of MEG at various temperatures. Moreover, the application of the developed tool in Python has proven to be suitable for parameter estimation and simulation purposes

Integração da simulação termoenergética com o processo de projeto: a análise de 6 casos

This work consists of the integrated design process analyses with thermal energetic simulation during the early design stages, based on six practical cases. It aims to schematize the integration process, identifying the thermal energetic analyses contributions at each design phase and identifying the highest impact parameters on building performance. The simulations were run in the DesignBuilder energy tool, which has the same EnergyPlus engine, validated. This tool was chosen due to the flexible and user friendly graphic interface for modeling and output assessment, including the parametric simulation to compare design alternatives. The six case studies energy tools are three architectural and three retrofit projects, and the author the simulations as a consultant or as a designer. The case studies were selected based on the commitment of the designers in order to achieve performance goals, and their availability to share the process since the early pre-design analyses, allowing schematizing the whole process, and supporting the design decisions with quantifications, including energy targets. The thermoenergetic performance analyses integration is feasible since the early stages, except when only a short time is available to run the simulations. The simulation contributions are more important during the sketch and detail phases. The predesign phase can be assisted by means of reliable bioclimatic guidelines. It was verified that every case study had two dominant design variables on the general performance. These variables differ according the building characteristics and always coincide with the local bioclimatic strategies. The adaptation of alternatives to the design increases as earlier it occurs. The use of simulation is very useful: to prove and convince the architects; to quantify the cost benefits and payback period to the retrofit designer; and to the simulator confirm the desirable result and report the performance to the client
