Information and communication technology (ICT) is a subject that is being discussed as a tool that is used within education around the world. Furthermore it can be seen as a tool for teachers to individualize students´ education. Students with literacy difficulties, such as dyslexia, are in constant need of new ways to learn, and new ways to be motivated to learn. The aim of this study is to see what research says in regard to how ICT can be used as a tool to help students with literacy difficulties. Literacy difficulties can be due to a number of things, such as the student has not been taught how to read, trouble within the family which can cause distress, or a neurological disorder such as dyslexia. Furthermore, the main research questions will focus on how ICT can be compared to traditional education forms, such as books and a more teacher centered education within the classroom, and whether ICT can be preferred. The results of this literature review indicates that ICT can be seen as a way for teachers to help students with literacy difficulties gain more self-esteem – something the literature tells us students with learning difficulties lack. The results also show how ICT can lead to a more individualized education. This is due to tools that increase reading comprehension and tools that give direct response when working with ICT, which helps students work more independently.

In the field of Information and Communication Technologies for Development (ICT4D) ICT use in education is well studied. Education is often seen as a pre-requisite for development and ICTs are believed to aid in education, e.g. to make it more accessible and to increase its quality. In this paper we study the access and use of ICT in a study circle (SC) education program in the south coast of Kenya. The study is qualitative reporting results based on interviews and observations with SC participants, government officers and SC coordinators and teachers. The study builds on the capability approach perspective of development where individuals’ opportunities and ability to live a life that they value are focused. The aim of the study is to investigate the capability outcomes enabled through the capability inputs access and use of ICT in education as well as the factors that enabled and/or restricted the outcomes. Findings show that many opportunities have been enabled such as an increase in the ability to generate an income, learning benefits, community development and basic human development (e.g. literacy and self-confidence). However, conversion factors such as a poorly developed infrastructure and poor IT literacy prevent many of the individuals from taking full advantage of the ICT and the opportunities it enables.

Information and communications technology (ICT) is a broad concept, which is often discussed in relation to the development of education. More specially, ICT can be seen as a tool to help teachers individualize students’ education. Students who have literacy difficulties, such as dyslexia, are in constant need of new techniques to help them learn and new tools to make their educational development easier. The aim of this thesis is to show what views teachers have regarding using ICT in English teaching at a sample of schools in the south of Sweden. A secondary part of the aim is to see what ICT tools, or other non ICT related methods, these teachers use to improve literacy skills for students with dyslexia.This empirical study is based on interviews with six participants. Previous research within the area is presented and different aspects of ICT within the National Agency for Education in Sweden, and the English syllabus, are also discussed. The results of this thesis show that ICT is seen as a helpful tool to make education easier for both students and teachers. Tools such as ViTal, Spell Right and Legimus are being used and the participants of the study also use iPads and Chromebooks in their teaching. According to the interviews, ICT can tribute to a fun way of learning and a more individualized education. Other non ICT related methods are also used to help students with dyslexia and these are often in terms of pictures in connection to words. These findings are based on a limited number of participants in a small area of south of Sweden. Therefore, further research is needed to see if the findings can be verified with more participants, in different parts of the country.

O presente trabalho de pesquisa refere-se à análise dos níveis de disponibilidade e implementação de programas de rastreabilidade, transparência e garantia ao longo da Cadeia Exportadora de Carne Suína Brasileira. Além disso, analisa o uso de práticas de ICT relacionadas à implementação desses programas e à valorização de atributos da carne suína. Os acontecimentos relativamente recentes envolvendo a falta de segurança alimentar levaram os consumidores a rever muitos hábitos de compra e consumo. Como conseqüência, aumentaram as exigências em relação às informações que permitem aos consumidores conhecer a origem e o processo produtivo dos alimentos. Os programas que permitem a rastreabilidade dos produtos, a transparência dos processos produtivos e a garantia da segurança alimentar e da qualidade, tornam-se fundamentais para atender as novas demandas do consumidor. Os objetivos dessa pesquisa são: caracterizar a Cadeia Exportadora de Carne Suína Brasileira; mensurar o nível de implementação de programas de rastreabilidade, transparência e garantia ao longo dessa cadeia; comparar a situação do Brasil em relação a outros países; e identificar as ICT relacionadas à implementação desses programas e os atributos da carne suína que são valorizados por elas. O método de pesquisa empregado é um levantamento associado à triangulação de dados obtidos por meio de outras fontes. O levantamento foi realizado com a aplicação de questionário estruturado enviado para todas as agroindústrias afiliadas a Associação Brasileira da Indústria Produtora e Exportadora de Carne Suína. Para mensuração do nível de implementação e comparação com outros países, é empregado o método de Liddell e Bailey (2001). Os resultados finais estão baseados nas respostas extraídas de 10 questionários recebidos devidamente respondidos. Os resultados revelam que a Cadeia Exportadora de Carne Suína Brasileira tem como ator principal a agroindústria. Com um sistema produtivo baseado na Integração Vertical, coordenado fundamentalmente pelas agroindústrias, estas determinam uma série de características produtivas da cadeia. Em termos de disponibilidade de programas de rastreabilidade, transparência e garantia, o Brasil figura em posição intermediária em relação a outros países importantes produtores e consumidores de carne suína. Como contribuição ao modelo de Liddell e Bailey (2001), faz uma análise comparativa entre a disponibilidade de programas de segurança alimentar e a efetiva implementação pelos atores da cadeia, mostrando que há uma defasagem significativa entre o que está disponível e aquilo que vem sendo utilizado na prática. Algumas práticas de ICT se sobressaem nas relações com a implementação desses programas e na valorização de atributos da carne suína. A Gestão da Cadeia de Suprimentos tem uso destacado entre as agroindústrias, bem como o Gerenciamento das Relações com Clientes, o Gerenciamento das Relações com Fornecedores, a Resposta Eficiente ao Consumidor, a Transferência Eletrônica de Fundos e a Troca Eletrônica de Dados.

O desafio de ofertar infraestrutura de serviços públicos nas regiões menos desenvolvidas do Brasil, geralmente mais afastadas dos grandes centros urbanos, mobiliza setores da sociedade na busca de abordagens novas e criativas que possam diminuir as grandes disparidades inter-regionais. Uma das carências vivenciadas por parte da população brasileira é a falta de acesso ao sistema financeiro, comprometendo a capacidade de plena participação dessas pessoas na economia, dificultando a geração e acúmulo de riqueza, situação essa presente na Ilha de Marajó, no estado do Pará, cuja maioria de seus dezesseis municípios apresenta Índice de Desenvolvimento Humano (IDH) baixo ou muito baixo. Para mudar essa realidade, uma iniciativa inovadora é a agência bancária itinerante instalada em barco, para atendimento a populações ribeirinhas de regiões com vasta extensão territorial, baixa densidade demográfica, dificuldades de transporte e limitações na oferta de tecnologia da informação e comunicação (TIC). Assim, essa pesquisa, com propósito exploratório e descritivo, tem como objetivo principal identificar, sob o ponto de vista das TIC, como os indicadores de inclusão financeira são influenciados pela atuação da Agência Barco na Ilha de Marajó. Além do estudo teórico, foi realizada investigação empírica, por meio de observação direta e entrevistas semiestruturadas com clientes e funcionários da Agência Barco, realizadas ao longo de quatro dias, em duas cidades da Ilha de Marajó. Para análise dos dados, foram aplicadas técnicas de análise de conteúdo às entrevistas, com objetivo de identificar a presença de elementos de inclusão financeira, transpondo os resultados para um modelo heurístico de infoinclusão dinâmica (2iD), o qual foi adaptado para contemplar constructos de inclusão financeira. O resultado da pesquisa demonstra que a Agência Barco consegue suprir as necessidades de acesso a serviços e produtos financeiros pela população da Ilha de Marajó, ao mesmo tempo em que se identifica oportunidades para ampliação de aspectos relacionados à educação financeira, possibilitando fortalecer os componentes dinâmicos do processo de inclusão financeira, com aumento da conscientização e consequente aumento da demanda por serviços e produtos financeiros.

Os efeitos da captura (perseguição, contenção em puçá e exposição aérea) no perfil sanguíneo do cortisol, glicose, cloreto, sódio, potássio, cálcio e na osmolaridade, hematócrito, hemoglobina, número de células vermelhas (CV) e volume corpuscular médio (VCM) foram investigados no pacu (Piaractus mesopotamicus). Um total de 132 peixes (49,7 ± 11,7 g) foi submetido à captura com 3 ou 5 minutos de exposição aérea. Nove peixes de cada tratamento foram amostrados 5, 15, 30, 60 minutos e 24 horas depois e outros nove peixes foram amostrados antes da captura e considerados controle. A captura resultou em aumento do cortisol e glicose no sangue 30 e 5 minutos depois da captura, respectivamente, independente do tempo de exposição aérea. Ambos os indicadores recuperaram os valores controle em 24 horas. Nos dois grupos de peixes, o cloreto plasmático diminuiu 60 minutos após captura e não recuperou os valores controle, enquanto o sódio sérico aumentou entre 15 e 30 minutos recuperando a condição controle em 24 horas. Não houve alteração significativa nos valores de potássio, cálcio, osmolaridade ou no hematócrito, hemoglobina, CV e VCM como consequência da captura. Os estressores sequenciais aplicados no pacu durante a captura ativaram o eixo cérebro-pituitária-interrenal (respostas do cortisol e glicose), mas a ativação do eixo cérebro-sistema simpático-células cromafins foi aparentemente moderada (respostas iônicas e hematológicas).

Performance and economic indicators of a large scale fish farm that produces round fish, located in Mato Grosso State, Brazil, were evaluated. The 130.8 ha-water surface area was distributed in 30 ponds. Average total production costs and the following economic indicators were calculated: gross income (GI), gross margin (GM), gross margin index (GMI), profitability index (PI) and profit (P) for the farm as a whole and for ten ponds individually. Production performance indicators were also obtained, such as: production cycle (PC), apparent feed conversion (FC), average biomass storage (ABS), survival index (SI) and final average weight (FAW). The average costs to produce an average 2.971 kg.ha-1 per year were: R$ 2.43, R$ 0.72 and R$ 3.15 as average variable, fixed and total costs, respectively. Gross margin and profit per year per hectare of water surface were R$ 2,316.91 and R$ 180.98, respectively. The individual evaluation of the ponds showed that the best pond performance was obtained for PI 38%, FC 1.7, ABS 0.980 kg.m-2, TS 56%, FAW 1.873 kg with PC of 12.3 months. The worst PI was obtained for the pond that displayed losses of 138%, FC 2.6, ABS 0.110 kg.m-2, SI 16% and FAW 1.811 kg. However, large scale production of round-fish in farms is economically feasible. The studied farm displays favorable conditions to improve performance and economic indicators, but it is necessary to reproduce the breeding techniques and performance indicators achieved in few ponds to the entire farm.

Hemograms and acute-phase proteins in adult male New Zealand White rabbits that had been experimentally infected orally with sporulated oocysts of Eimeria stiedai were evaluated over a 28-day period. Fifty animals were used, divided into two groups: group A infected with 1 x 10(4) sporulated oocysts of E. stiedai and group B inoculated with distilled water. on the seventh day after infection, the infected animals presented anemia and leukocytosis with neutrophilia and monocytosis. Protein fractionation by means of electrophoresis identified 19 acute-phase proteins with molecular weights ranging from 24 to 238 kD. Ceruloplasmin, transferrin and haptoglobin showed high levels on the seventh day after infection, with gradual increases in their concentrations until the end of the experimental period. Thus, from the data of the present study, E. stiedai is considered to be a pyogenic etiological agent for which the infection level can be monitored through the leukocyte count and serum concentrations of ceruloplasmin, transferrin and haptoglobin, and these can be recommended as complementary tests.

The indiscriminate management and use of soils without moisture control has changed the structure of it due to the increment of the traffic by agricultural machines through the years, causing in consequence, a soil compaction and yield reduction in the areas of intensive traffic. The purpose of this work was to estimate and to evaluate the performance of preconsolidation pressure of the soil and shear stress as indicators of changes on soil structure in fields cropped with sugarcane, as well as the impact of management processes in an Eutrorthox soil structure located in São Paulo State. The experimental field was located in Piracicaba's rural area (São Paulo State, Brazil) and has been cropped with sugarcane, in the second harvest cycle. The soil was classified by Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) [Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 1999. Centro Nacional de Pesquisa de Solos. Sistema Brasileiro de Classificao de Solos, Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), Brasilia, 412 pp.] as an Eutrorthox. Undisturbed samples were collected and georeferenced in a grid of 60 m x 60 m from two depths: 0-0.10 m (superficial layer - SL) and in the layer of greatest mechanical resistance (LGMR), previously identified by cone index (CI). The investigated variables were pressure preconsolidation (sigma(p)), apparent cohesion (c) and internal friction angle (phi). The conclusions from the results were that the SLSC was predicted satisfactorily from up as a function of soil moisture; thus, decisions about machinery size and loading (contact pressures) can be taken. Apparent cohesion (c), internal friction angle (phi) and the Coulomb equation were significantly altered by traffic intensity. The sigma(p), c and phi maps were shown to be important tools to localize and visualize soil compaction and mechanical resistance zones. They constitute a valuable resource to evaluate the traffic impact in areas cropped with sugarcane in State of São Paulo, Brazil. (C) 2008 Elsevier B.V. All rights reserved.

Different nutritional-state indicators of HIV-positive individuals undergoing antiretroviral therapy
Resumo:
This study aimed at learning about the nutritional profile of HIV-positive individuals undergoing antiretroviral therapy and at comparing the performance of nutritional-state indicators. A transversal study was performed on 94 patients attending the Tropical Diseases Outpatient Hospital of Botucatu Medical School (FMB)-UNESP. The body mass index (BMI) and the classification by Papini-Berto (PB) were used to evaluate nutritional state, aiming at detecting malnutrition and obesity. The waist-to-hips ratio (W/HR) and waist circumference (WC) were adopted for identification of abdominal obesity and lipodystrophy. According to BMI, most of the individuals were eutrophic, followed by 30.9% overweight and 6.4% malnourished. By using the PB classification, the frequency of malnourished increased (22.3%). The analysis of the PB classification in relation to BMI indicated that the former presented high sensitivity and good specificity for malnutrition diagnosis, namely 100% and 83%, respectively. The prevalence of abdominal obesity was 7.44% according to WC, and a higher prevalence (38.3%) was observed when taking W/HR into account. There was significant positive association between nutritional diagnosis according to PB and T CD4(+) lymphocyte. The results support the use of PB classification for malnutrition detection as well as that of BMI and W/HR for overweight and fat redistribution.

Background: Since human diets contain many components that may work synergistically to prevent or promote disease, assessing diet quality may be informative. The purpose of this study was to investigate the association between quality diet, by using Healthy Eating Index (HEI), and metabolic risk indicators in postmenopausal women.Methods: This cross-sectional study included a total of 173 Brazilian women, aged 45-75 years, seeking healthcare at a public outpatient center. Food consumption assessed by 24 h-recall food inquiry was used to calculate HEI scores: >80 implied diet good, 80-51 diet needed improvement, and <51 diet poor. Anthropometric data included: body mass index (BMI = weight/height(2)), waist-circumference (WC), body fat (%BF) and lean mass (%LM). Data on total cholesterol (TC), high density lipoprotein cholesterol (HDLC), low density lipoprotein cholesterol (LDLC), and triglycerides (TG) were also collected. Fisher's Exact test, and logistic regression method (to determine odds ratio, OR) were used in the statistical analysis.Results: Overweight and obesity were observed in 75.7% of the participants. Excessive %BF (> 35%) was observed in 56.1%, while %LM was reduced (<70%) in 78.1%. WC was elevated (= 88 cm) in 72.3%. Based on HEI values, diet quality was good in 3% (5/173), needed improvement in 48.5% (84/173), and was poor in 48.5% (84/173) of the cases. In this group, 75% of women had high intakes of lipids (> 35%), predominantly saturated and monounsaturated fat. on average, plasma TC, LDLC, and TG levels were higher than recommended in 57.2%, 79.2% and 45.1% of the women, respectively, while HDLC was low in 50.8%. There was association between HEI scores and the %BF that it was higher among women with HEI score < 80 (p = 0.021). There were not observed significant risk associations between HEI and lipid profile.Conclusion: Among the Brazilian postmenopausal women attending a public outpatient clinic, diet was considered to need improvement or to be of poor quality, attributed to high saturated fat ingestion, which probably caused a negative impact on metabolic risk indicators, namely body composition.

Objective. to evaluate anthropometric indicators of body fat and their association with metabolic risk markers in postmenopausal women.Methods. A cross-sectional study with 80 Brazilian women (40-70 years) was carried out. Body mass index (BMI = weight/height(2)), waist circumference (WC) and waist-to-hip ratio (WHR) were obtained for anthropometric evaluation. Trunk fat mass (TFM) was measured by dual-energy X-ray absorptiometry. The following metabolic variables were evaluated: total cholesterol (TC), HDL, LDL, triglycerides (TG), as well as glycemia and insulin to determine insulin resistance (HOMA-IR).Results. Overweight and obesity were observed in 81% of the women. Values of WC >88 cm were observed in 68.5% of the women. on average, TC, LDL and TG levels were above normal levels in 60, 50 and 42.5% of the women, respectively; and HDL was normal in 82.5%. IR was observed in 37.5% of the women. Positive correlations were found between anthropometric indicators and TFM (P < 0.05). WC was most correlated with TFM (r = 0.92), followed by BMI (r = 0.88) and by WHR (r = 0.48; P < 0.05). All anthropometric indicators and TFM showed significant negative correlations with HDL and significant positive correlations with HOMA-IR (P < 0.05). Only WHR was significantly associated with dysglycemia (R(2) = 12%), hypertriglyceridemia (R(2) = 17%) and decreased HDL (R(2) = 27%). WC was significantly associated with HOMA-IR (R(2) = 34%).Conclusion. WC and WHR are anthropometric measures that showed strong correlation with TFM and with metabolic risk markers in postmenopausal women.

We aim to investigate the effectiveness of a 10-week lifestyle intervention focusing on physical activity and high fiber intake for reducing indicators for metabolic syndrome in overweight-obese individuals. A prospective study of 50 overweight (OW) adults (22 in the general educational group - G1; 28 in the high fiber nutrition group - G2) was performed. Both groups were offered dietary counseling and supervised exercise. Clinical, anthropometric, dietary and plasma biochemical tests were performed at baseline - time 0 (T0) and after 10 weeks - time 1 (T1). Both groups improved their dietary quality, but only G2 presented higher intake of fruit and vegetables (servings/day), higher plasma beta-carotene levels and a 24% reduction of MetS incidence. Additionally G2 showed greater reductions in body fat (4%), and waist circumference (7%), obesity class III (2%) and obesity class II (14%) rate. Lifestyle intervention, including a high dietary fiber intake, improved healthy eating index and decreased body fat composition and plasma lipid concentrations leading to MetS incidence reduction.
