Comparação dos tempos de geração e digitação de laudos radiológicos entre um sistema eletrônico baseado em voz sobre IP (VoIP) e um sistema tradicional baseado em papel

OBJETIVO: Comparar os tempos de geração e digitação de laudos radiológicos entre um sistema eletrônico baseado na tecnologia de voz sobre o protocolo de internet (VoIP) e o sistema tradicional, em que o radiologista escreve o laudo à mão. MATERIAIS E MÉTODOS: Foi necessário modelar, construir e implantar o sistema eletrônico proposto, capaz de gravar o laudo em formato de áudio digital, e compará-lo com o tradicional já existente. Por meio de formulários, radiologistas e digitadores anotaram os tempos de geração e digitação dos laudos nos dois sistemas. RESULTADOS: Comparadas as médias dos tempos entre os sistemas, o eletrônico apresentou redução de 20% (p = 0,0410) do tempo médio de geração do laudo em comparação com o sistema tradicional. O tradicional foi mais eficiente em relação ao tempo de digitação, uma vez que a média de tempo do eletrônico foi três vezes maior (p < 0,0001). CONCLUSÃO: Os resultados mostraram diferença estatisticamente significante entre os sistemas comparados, sendo que o eletrônico foi mais eficiente do que o tradicional em relação ao tempo de geração dos laudos, porém, em relação ao tempo de digitação, o tradicional apresentou melhores resultados.

Os fios da trama: grandes temas da música popular tradicional brasileira

Nos cantos, danças e folguedos populares brasileiros, podemos encontrar um feixe de motivos entrelaçados, padrões multicores de um tecido de que conviria procurar e acompanhar cada um dos fios aí urdidos e tramados, agrupando-os segundo sua textura ou coloração. Essas diferentes linhas temáticas, os fios da trama das expressões artísticas e religiosas do povo brasileiro são o assunto deste artigo, que procura analisar formas culturais caracterizadas pela hibridação, as quais transitam muitas vezes na ambiguidade entre resistência e aceitação de um padrão cultural dominante. O dinamismo dos arranjos de um certo número de motivos condutores recorrentes no âmbito da cultura de tradição oral brasileira nos leva a especular sobre os processos de formação de suas práticas artísticas, bem como sobre sua circulação num país de dimensões continentais.

Dança, corpo e desenho: arte como sensação

Este trabalho busca refletir sobre o estatuto do corpo e do movimento nas artes a partir da noção de sensação, como empregada no pensamento do filósofo francês Gilles Deleuze. Tal propósito se fará a partir do singular encontro entre os trabalhos de um pintor/desenhista e um dos mais emblemáticos bailarinos clássicos. O corpo em movimento, quando atinge o estado de dança, não se reduz a uma forma, a uma representação, nem a uma mecânica. Antes, pelo contrário, sua leveza singular afeta-nos sobremaneira. Tal afecção será tomada como fio condutor de nossa análise, tendo em vista as diferentes sensações e expressões que pode suscitar. A sensação de um corpo que dança pode expressar-se na dança em si como também no desenho. Que relações esses diferentes meios de expressão do corpo dançarino podem estabelecer entre si? Que acontecimentos singulares podem emergir nesse encontro particular? Antes que forma, linhas de força e expressão. Corpo-vibração, torrente de afectos e perceptos, constituindo sensações que diferentes meios artísticos expressam diferentemente.

Relative growth of spider crab Acanthonyx scutiformis (Dana, 1851) (Crustacea, Decapoda, Majidae)

The dimensions of chelar propodus and abdomen were utilized for the morphometric analysis about the relative growth studies of Acanthonyx scutiformis (Dana, 1851). A total of 297 specimens (114 males and 183 females), was collected in Ubatuba, State of São Paulo, Brazil. The animals were sexed and soarted to maturation phase (immature and mature). The following measurements were made: carapace (length and width), abdomen width and chelar propodus (length and height). In this study was applicated the power function (y= a.x(b)), in which the growth was considered positive allometric with isometric with b=1, and negative allometric with b<1. The alometry becomes isometric, when the results concerning immature and mature females and males are analysed. In the Brachyura male chelipeds are utilized in territorial defense, fight, display and courtship and female abdomens are utilized as a chamber that protect and incubate the eggs.

Distribution of Neohelice granulata (Dana 1851) in its northernmost latitudinal occurrence in a tropical mangrove forest, Brazil (Crustacea, Decapoda, Brachyura, Grapsoidea, Varunidae).

Neohelice granulata ecological distribution was evaluated in its northernmost latitudinal occurrence in a Brazilian tropical mangrove (23[degree]13'4" S, 44[degree]42'47" W). Samples were collected in three sites along the main river in the mangrove. Crabs were manually captured by two people, 15 min each, at low tide periods. The sex of the animals was assessed and carapace width measured. The size-frequency distribution was determined in each site. Environmental factors (salinity, temperature, organic matter and sediment texture) were analyzed, compared among sites and related to crab abundance and size in each site. Crab abundance decreased with the distance from the sea. Juvenile crabs were more frequent next to the sea, whereas larger and ovigerous ones were mainly found in the most distant site. Crab size was proportional to the organic matter percentage in the sediment. N. granulata spatial distribution varies along the river course, which is probably related to the most productive areas that have more nutrients available; this may also occur in order to prevent intraspecific competition.

Size distribution and sex ratio in the spider crab Epialtus brasiliensis (Dana 1852) associated with seaweed on a rocky shore in southeastern Brazil (Crustacea, Decapoda, Brachyura, Majoidea, Epialtidae).

This study analyzed a population of the spider crab Epialtus brasiliensis, in regard to its size distribution, sex ratio and Sexual maturity. The study was conducted on a rocky shore in the Ubatuba region, state of Silo Paulo, Brazil, where a wide strip of algae covers the intertidal zone. A total of 378 specimens were obtained: 200 males (128 juvenile and 72 adult crabs) and 178 females (46 juveniles and 132 adults). Their Sizes ranged from 3.4 to 16.7 mm carapace length (CL). Taking into account that the pubertal and terminal molts are coincident in majid crabs, the maximum sizes attained by males and females are especially dependent on the factors that influence sexual maturity, mainly food resources, temperature and intraspecific competition. Males of E. brasiliensis occurred in all size classes, whereas females occurred only as far the 10th size class (12-13 min CL). file total sex ratio did not differ statistically from 1 : 1, but when the juvenile and adult specimens were analyzed separately the differences between sexes were significantly different, with higher proportions of immature males and mature females. The CL50 calculated for males and females was 10.4, and 6.9 min CL, respectively. Thus, males reach their sexual maturity at a larger size than females. This feature may be important for the reproductive strategy of this species, because larger males probably have greater reproductive Success.

A dança “en-cena” o outro: prerrogativas para uma educação estética através do processo criativo

The dance installs in the body another scene of senses that raises the creative performance and not that can be speculated about it. There, "who dance" is the Other one, making the body acting of another manner, beyond the systemic contour of Ego. Without the presence of this forged performance, the body would not pass of one ruled machine in function of something and not in favor of himself, as original movement of himself. This article intends to make a reflection about the corporal perception in the dance, trying to point out the creative performance. So, we opened a way to understand the process creative as field of corporal sensitization where the educative intervention is accomplished in the body.

Concepcoes estratigraficas em analise de Bacias: A) a estratigrafia tradicional

This article is the first part of an overall theme dealing with different stratigraphic approaches to basin analysis. The traditional stratigraphy, based on formal units, is discussed here with an attempt to analyse their principles, methods and purposes. Using the Permian carboniferous sequence of Parana Basin as a paradigm, some critical inferences concerning the limitations of such an approach in environmental reconstruction are attained. -English summary

Análise de crescimento e produtividade de cultivares de arroz de terras altas dos tipos tradicional, intermediário e moderno

The growth analysis allows the characterization and understanding of the upland rice cultivars development. This study aimed at characterizing, by using the growth analysis, the physiological components and agronomic performance, as well as the differences among traditional, intermediate and modern upland rice cultivars. The experiment was conducted under upland rice conditions, favored by the use of supplementary irrigation. The experimental design was randomized blocks, with three treatments consisting of traditional (Caiapó), modern (Maravilha) and intermediate (BRS Primavera) cultivars and eight replications. The leaf area index (LAI), instantaneous growth rate (IGR), relative growth rate (RGR), net assimilation rate (NAR) and specific leaf area (SLA), as well as grain yield and yield components, were evaluated. The intermediate and traditional cultivars presented the highest total dry matter accumulation rate, while the traditional and modern ones showed the highest LAI. The intermediate cultivar presented the highest IGR, RGR, NAR and SLA levels, as well as the highest grain yield, as a consequence of the higher spikelet fertility and 1,000 grain mass.

A influência da dança na percepção de estruturas rítmicas monotônicas em adolescentes surdos

Dance activities were administered to a group of deaf adolescents via visual and auditory stimuli in order to improve their perceptions of monotonic rhythmic structures. Status of psychomotor development was also assessed before and after participation in the program. Twenty deaf adolescents (ages between 12 and 13 years) were divided into two groups, experimental (EG) and control (CG). Before and after participating in the program for 26 weeks, participants were evaluated in rhythmical tasks adapted from the classical test of M. Stambak. The tasks included the perception of drum beats, actually viewed hit movements, or heard via a sound amplifier. Psychomotor tests were administered only to the EG. The period of practice with dance activities changed the individuals' performance in the monotonic rhythmic test. Also, the success rate improved in both, visual and auditory input tasks. Individuals in the CG showed no changes in performance. For the EG, in the post-test, the status of psychomotor development was six months below the target age of the tests (i.e., 11 years). Findings suggested that dance activities can change deaf individuals' auditory perception of rhythmic structures. Participation in such a program can also positively affect psychomotor development. © FTCD/FIP-MOC.
