O bóia-fria e a (de)formação do espaço agrário de Florestópolis-PR
No full textDissertação (Mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas.O presente trabalho discute o assalariado rural temporário, o bóia-fria, no processo de (de)formação do espaço agrário do Município de Florestópolis, que se localiza no norte do Paraná. As análises referentes ao Município em apreço foram realizadas através de reflexões sobre a estrutura fundiária, o uso da terra e a modernização da agricultura. Além disso, discutimos as relações de trabalho no campo, privilegiando a problemática dos bóias-frias. Enfatiza-se que os bóias-frias são trabalhadores desprovidos dos meios de produção e encontram oferta de serviços em períodos sazonais, sendo obrigados a vender sua força de trabalho para garantir sua sobrevivência. Em Florestópolis, a cultura agrícola que mais absorve mão-de-obra destes trabalhadores é a cana-de-açúcar. A colheita de cana-de-açúcar acontece, normalmente, no período de junho a dezembro. No decorrer do trabalho, buscamos diagnosticar algumas potencialidades do grupo em discussão, tais como questões relacionadas à reforma agrária e suas aspirações para o futuro. Assim, de maneira geral, procuramos entender a dinâmica desses trabalhadores no processo de transformação do espaço agrário do Município de Florestópolis
A poesia visual de Miguel de Frias: o universo da visualidade na poesia
No full textEsta pesquisa discute a trajetória da visualidade na poesia, tendo como foco principal as obras do artista Miguel de Frias. O trabalho buscou fontes de visualidade poética desde a Grécia Antiga, passando pelo movimento da Poesia Concreta, até a poesia visual da atualidade. Aborda com brevidade a história do design e como trabalha o profissional designer. Relaciona a construção do projeto de design gráfico e da poesia visual, mostrando até que ponto eles se aproximam e o que os distancia. Traz o conhecimento de um pouco da vida e trajetória profissional do artista Miguel de Frias, para chegar a suas poesias. Foram analisados seis poemas visuais do artista, com o olhar particular da autora. Justifica-se, assim, uma ampla pesquisa bibliográfica para a fundamentação teórica e uma entrevista realizada com FriasThis research discusses the history of visual poetry, focusing mainly on the works of artist Miguel de Frias. This work sought sources of visual poetry from Ancient Greece, throughout the movement of concrete poetry, until today’s visual poetry.

Modelling the effect of asparaginase in reducing acrylamide formation in biscuits
No full textThe influence of asparaginase on acrylamide formation, as well as colour development, in short dough
biscuits was studied. In particular, asparaginase concentration, incubation time and temperature were
changed according to an experimental design. As acrylamide formation was found to vary significantly
between biscuits obtained by using the same ingredients and process, a mixed effect model was used
to model variation of acrylamide concentration. By contrast a fixed effect model was used for colour polynomial
analysis. Within the range of study, the overall results allowed the best conditions for minimising
acrylamide formation to be found. It can be suggested that acrylamide development was at a minimum at
intermediate asparaginase concentrations, as well as at the lowest time and temperature of incubation.
Asparaginase addition did not significantly affect the colour of the final product, although the quadratic
term of the incubation temperature did slightly
Delgado-Frias, “Pipelined multipliers for reconfigurable hardware
No full textReconfigurable devices used in digital signal processing applications must handle large amounts of data in vector form. Most signal processing algorithms use multiplication extensively; thus, the hardware must support this operation to achieve high performance. However, mapping a multiplier on traditional fine-grain devices produces a complex structure whose performance is limited by the routing overhead. In this paper, we present a novel pipelined multiplier structure suitable for medium-grain and coarse-grain reconfigurable cell arrays. We first implement an unsigned n-bit multiplier using m-bit cells. Then, we show how the same structure can work with two’s-complement data with small changes to the configuration. The structure requires ⎡n/m ⎤ 2 cells, but can execute vector operations in a pipelined fashion. We also discuss the benefits of using a hierarchical design for large multipliers. 1
Evaluation of a personalized digital library based on cognitive styles: Adaptivity vs. adaptability
No full textPersonalization can be addressed by adaptability and adaptivity, which have different advantages and disadvantages. This study investigates how digital library users react to these two techniques. More specifically, we develop a
personalized digital library to suit the needs of different cognitive styles based on the findings of our previous work (Frias-Martinez, et al., in press). The personalized digital library includes two versions: adaptive version and
adaptable version. The results showed that users not only performed better in the adaptive version, but also they perceived more positively to the adaptive version. In addition, cognitive styles have great effects on users’ responses
to adaptability and adaptivity. These results provide guidance for designers to select suitable techniques to develop personalized digital libraries
Gastric cancer risk in patients with atrophic gastritis and intestinal metaplasia in OLGA and OLGIM stages III and IV: systematic review and meta-analysis
No full textilustraciones, diagramasIntroducción y objetivo: Estudios recientes han encontrado que pacientes con OLGA II, también pueden tener riesgo de cáncer gástrico (CG) a largo plazo y más aún si tienen familiares de primer grado con CG. El objetivo del presente metaanálisis es determinar si los estadios de OLGA II-IV tienen riesgo de CG y cuál es su magnitud, así como también estimar si el riesgo aumenta cuando hay familiares de primer grado con CG.
Metodología: Revisión sistemática y metaanálisis. Se buscarán en varias bases de datos, incluyendo PubMed, EMBASE, Medline y la biblioteca Cochrane, artículos publicados en los últimos 10 años hasta mayo de 2024 sobre la asociación entre los diferentes estadios OLGA/OLGIM y el riesgo de GC. Análisis estadístico con estimación del efecto en términos de Odds Ratio (OR), riesgo relativo (RR) e intervalo de confianza del 95%. La heterogeneidad se estimará con I2 y Chi2.
Resultados: De 273 artículos recuperados mediante nuestra búsqueda bibliográfica, se incluyeron un total 28 estudios que comprendían 23390 pacientes, se incluyeron 15 estudios de casos y controles, corte transversal, y 13 estudios de cohortes. El metaanálisis demostró una asociación significativa entre los estadios II-IV de OLGA/OLGIM y cáncer gástrico. El análisis de subgrupos en poblaciones con baja prevalencia de infección por H. pylori no encontró asociación del puntaje OLGIM en los estudios de cohorte.
Conclusiones: Se presenta una versión resumida de las asociaciones estimadas de los diferentes estadios de OLGA/OLGIM y riesgo de CG (Texto tomado de la fuente).Introduction and objective: Recent studies have found that patients with OLGA II
may also be at risk of gastric cancer (GC) in the long term and even more so if they
have first-degree relatives with GC. The aim of the present meta-analysis is to
determine whether OLGA stages II-IV are at risk of GC and what is its magnitude,
as well as to estimate whether the risk increases when there are first-degree
relatives with GC.
Methodology: Systematic review and meta-analysis. Several databases, including
PubMed, EMBASE, Medline and Cochrane library, will be searched for articles
published in the last 10 years until May 2024 on the association between different
OLGA/OLGIM stages and GC risk. Statistical analysis with estimation of effect in
terms of Odds Ratio (OR), relative risk (RR) and 95% confidence interval.
Heterogeneity will be estimated with I2 and Chi2.
Results: Of 273 articles retrieved through our literature search, a total of 28 studies
comprising 23390 patients were included, 15 case-control, cross-sectional, and 13
cohort studies. The meta-analysis demonstrated a significant association between
OLGA/OLGIM stages II-IV and gastric cancer. Subgroup analysis in populations with
low prevalence of H. pylori infection found no association of OLGIM score in cohort
studies.
Conclusions: A summarized version of the estimated associations of different
OLGA/OLGIM stages and GC risk is presented.Especialidades MédicasEspecialista en GastroenterologíaRevisión sistemática y metaanálisis.
