Desenvolvimento de uma plataforma de software para a modelagem digital de terrenos baseada em TIN

Topographical surfaces can be represented with a good degree of accuracy by means of maps. However these are not always the best tools for the understanding of more complex reliefs. In this sense, the greatest contribution of this work is to specify and to implement the architecture of an opensource software system capable of representing TIN (Triangular Irregular Network) based digital terrain models. The system implementation follows the object oriented programming and generic paradigms enabling the integration of various opensource tools such as GDAL, OGR, OpenGL, OpenSceneGraph and Qt. Furthermore, the representation core of the system has the ability to work with multiple topological data structures from which can be extracted, in constant time, all the connectivity relations between the entities vertices, edges and faces existing in a planar triangulation what helps enormously the implementation for real time applications. This is an important capability, for example, in the use of laser survey data (Lidar, ALS, TLS), allowing for the generation of triangular mesh models in the order of millions of points.

Association between bone mass and functional capacity among elderly people aged 80 years and over

Objetivo:Analisar a associação entre a massa óssea e capacidade funcional de idosos com 80 anos ou mais.Métodos:A amostra foi composta por 93 idosos entre 80 e 91 anos (83,2 ± 2,5 anos), 61 mulheres (83,3 ± 2,7 anos) e 32 homens (83,1 ± 2,2 anos) da cidade de Presidente Prudente. A avaliação da massa óssea foi feita pela absorptiometria de dupla energia de raios X (DXA), na qual foram mensurados os valores de conteúdo mineral ósseo (BMC) e densidade mineral óssea (BMD) do fêmur e da coluna (L1-L4). A capacidade funcional foi avaliada por meio dos testes de velocidade para caminhar, equilíbrio estático e força de membros inferiores contidos no questionário Saúde, Bem-Estar e Envelhecimento (Sabe). As variáveis da massa óssea e capacidade funcional foram categorizadas de acordo com os valores de mediana e a pontuação obtida nos testes, respectivamente. Para tratamento estatístico fez-se o teste qui-quadrado, o software usado foi SPSS (13.0) e o nível de significância estabelecido foi de 5%.Resultados:Os idosos do sexo masculino com maior desempenho nos testes funcionais apresentaram maiores valores de BMC de fêmur comparados com os de menor desempenho, resultado não encontrado quando avaliadas as mulheres.Conclusão:Dessa forma, a massa óssea do fêmur para idosos longevos do sexo masculino está associada à capacidade funcional. A avaliação constante da massa mineral óssea e a prática de atividade física ao longo da vida seriam medidas para prevenção das quedas em idosos.

Accuracy in dictation after improvement of reading and copying skills in a student with learning difficulties

The aim of this study was to use systematic teaching in a clinical setting using software to teach reading and writing in one boy with learning difficulties and obtain accurate performance in dictation. In the pre-test, the student showed good performance in matching-to-sample tasks (96% in matching printed words to dictated words; 88% in matching pictures to dictated words), although he obtained a low percentage of correct answers in the dictation of constructed responses (52%) and manuscripts (24%). The teaching strengthened the selection of printed words matched to dictated words and copying words. The student obtained 100% correct answers in the teaching tasks. In post-tests of dictation, he obtained 100% correct answers in constructed response and 96% correct answers in manuscripts. The results indicate that carefully teaching copying may promote accuracy in the performance of responding to minimal units in dictation tasks.

Tratamento químico de sementes de milho e o teste de condutividade elétrica

In different crops, the seeds treatment with the use of fungicides and/or insecticides has been performed before the storage or in the seeding moment as a guarantee form of longer conservation period and adequate initial stand. However, it is not known if the various products used for the treatment interfere with test results of electrical conductivity of corn seeds. The experimental design was completely randomized and the analysis carried out in a factorial 5x5x2 with four replications. The treatments consisted of five cultivars of corn (DKB 390YG, DKB 185YG, 2B710, AGN-30A91HX and AL Bandeirante) treated with four insecticides (imidacloprid+thiodicarbe, thiamethoxam, fipronil, fipronil+piraclostrobin+thiophanate-methyl), and the control previously treated by the company with fungicides (fludioxonil+metalaxyl-M e captan) and insecticides (pirimiphos-methyl, deltamethrin e bifenthrin), analyzed in two different times (after treatment and at 35 days of storage). Seeds were subjected to tests of germination, electrical conductivity and water content. The results showed that the treatment of corn seeds with insecticides and fungicides doesn't interfere on the test results of electric conductivity, even if the analysis is made after 35 days of storage of seeds.

Influência do estímulo verbal no tempo do teste de escada

Introduction: The stair-climbing test (SCT) is considered a submaximal test of simple implementation and easy access, which assesses the individual’s functional capacity. Although widely used in surgical patients, there is no standardization regarding the height of the stair and verbal stimulus. Objectives: It was determine if verbal stimulus changes the stair-climbing time (SCt) in individuals over 50 years-old. We compared oxygenation, blood pressure, pulse, respiratory rate and Borg scale between SCT performed with and without stimulation. Methods: We evaluated individuals with ages greater than 50 years-old that performed two STC (with and without verbal stimulation), in the stair with 44 steps, achieving 7.04 m in height and recording the time to climb the stair. The systolic blood pressure (SBP) and the diastolic blood pressure (DBP), respiratory rate (RR), pulse, oxygen saturation (SpO2 ) and Borg scale were evaluated before and after the tests. The time in the SCT with and without stimulation were compared using the Student test-t and the other variables were compared using the ANOVA test (p<0.05). Results: The average age was 59.75±6,40 years old in the 21 evaluated individuals. The time in the SCT without stimulus was significantly higher than the one with stimulus. The SBP, pulse, RR and Borg scale were significantly increased when compared to the SCT with and without stimulus. Oxygenation and DBP didn´t have significant differences at any time of the study. Conclusions: The time in the SCT was lower when performed with verbal stimulus. The SBP, pulse, RR and Borg scale changed significantly after the SCT with and without stimulus, remarking that this change was greater in the SCT with stimulus.
