This research aimed to analyze the dynamics established between the activity of the teacher in Distance Education (DE) and professional gender of teaching, in terms of impact of DE in teacher s usual professional activity. Previous studies showed that one of the central discussions concerning DE refers to the role that the teacher is called to perform. The present research, based on theoretical and methodological assumptions issued from Clinic of Activity, analyzed the impact referred above. This central aim was operationally executed along three main stages: 1) survey study for description of socio-professional profile of teachers working in DE in two universities from Natal (RN-Brazil), 2) clinical analysis of professional activity of teachers working in DE, taking into account four simultaneous levels of psychological constitution and development of human activity: personal, interpersonal, transpersonal and impersonal; 3) analytical focus on transpersonal context in order to understand the influence of pedagogical practice in DE on professional gender of teaching. Documental research, audio recorded voice data and a multiple choice Likert scale questionnaire concerning socio-professional information were used as procedural tools. The qualitative-clinical procedural tool of instruction to the double , firstly proposed by Clinic of Activity research group, was used in order to obtain oral productions concerning professional activity. Data issued from stage 1 (n=70, 28 men and 41 women) was submitted to descriptive and inferential statistical analyzes. 65.7% of the sample worked in a public institution, 30% in a private institution, and 4.3% in public and private institutions. 31.4% of the sample of participants was formed by teachers having a master degree, 28.6% were doctors and 26.3% had degrees of specialists. 54.3% of participants acted as remote tutor, and 44.3% were regents teachers. After descriptive multidimensional cluster analysis, two groups emerged (remote tutors and regents teachers), the most important variables in terms of contributions to this distinction being: professional function, level of graduate formation, level of income, activities and forms of entry in DE. Clinical analysis of data produced by two participant-teachers of each group, issued from instruction to the double technique, was performed. This analysis indicated the existence of different models of distance education. A general concern referring to the need of both taking into account information technology and pedagogical attitudes was detected. On the other hand, participant-teachers considered that participation in DE activities could bring relevant contributions to general professional gender of teaching. . Finally, teachers warned against certain formats of organization of teachers professional activity, as found in the domain of DE, since these activities could promote the intensification and individualization of teachers` work activity, and even the worsening of relations, rather than exchanges and shares through collective bargaining. This process could compromise the renew of the professional gender, by losing its historical roots and diminishing activity possibilities of teachers in their labor context

This dissertation aims to analyze the causal relationship between the quality of tourist services, satisfaction with the attributes and globally, fidelity and image of tourist destinations. Therefore, it was conducted an exploratory, descriptive research with quantitative analytical approach. Data collection was performed by a questionnaire addressed to tourists at the Augusto Severo International Airport and Bus station of Natal, the main points of entry and exit of tourists. The composition was simple random sampling by reaching the final number of 400 tourists interviewed. Among the main results, is an assessment of the quality of the components of the destination. It was noted that nine are the dimensions of perceived quality of tourism products and services of ―Sun and Sand‖ segment, that is, Beaches and Facilities, Public Equipment, Catering Services, Transportation, Hotel Equipment, Hotel Services, Entertainment & Attractions, Access to the Hotel and Hospitality. Moreover, it was concluded that the Preview Tourism Destination Image has little direct influence in the Consumer Satisfaction, and only indirectly in the Post-Purchase Behavior. While the Complex Tourism Destination Image exerts strong and direct influence on both factors, in the Customer Satisfaction Process and Loyalty, the dimensions of quality also claimed to be strongly influences both factors

Na aplicação de produtos fitossanitários, a utilização de equipamentos que controlam automaticamente as seções da barra e a pulverização já é realidade; entretanto, ainda não há resultados que demonstrem a sua eficácia. Por esse motivo, este trabalho teve por finalidade desenvolver uma metodologia para a avaliação de um equipamento que controla automaticamente as seções e a pulverização. Avaliou-se um controlador automático de seções e pulverização de mercado, e, para tanto, foram utilizados três níveis de acurácia do sinal de GPS (algoritmo interno, SBAS e RTK), três ângulos para a simulação de entrada e saída da barra de pulverização em relação à borda do talhão (0; 45 e 60º ) e três velocidades de trabalho (1,66; 5,00 e 8,33 m s-1). A metodologia proposta possibilitou a determinação dos tempos e distâncias de abertura e fechamento das seções. Os coeficientes de variação para os tempos e distâncias de abertura e fechamento das seções indicaram uma variação considerável. Houve interações significativas em função do tipo de sinal de GPS. A configuração recomendada pelo fabricante e adotada para a avaliação do controlador automático de seções e pulverização não atende a todas as situações simuladas.

Paracoccidioidomycosis is caused by Paracoccidioides brasiliensis, a dimorphic fungus, prevalent in tropical and subtropical America. It is rare in the United States of America, Canada, Asia and Europe and in these countries it is related to immigrants from endemic areas. Paracoccidioidomycosis associated with immunosuppression runs a course with rapid progression and dissemination of the disease, with many cutaneous lesions. The mortality rate is up to 35% when associated with HIV infection or AIDS. The diagnosis depends on visualization of the agent through direct examination, histopathology, or culture. First choice treatment is done with Amphotericin B deoxycholate. Itraconazole is an option for long term treatment. Sporotrichosis is caused by Sporothrix schenckii, the species of reference. Other species have been considered such as: Sporothrix brasiliensis, S.globosa and S.mexicana and the S.schenckii var. lurei. It is a ubiquitous disease although more prevalent in tropical and subtropical areas. Currently, it has been reported as a zoonotic disease of cats and dogs, with transmission to their owners in the city of Rio de Janeiro (Brazil). Sporotrichosis associated to immunosuppression is uncommon or underreported. There were 34 cases in association with HIV infection or AIDS reported so far. Presenting with disseminated disease and non cutaneous lesions including joints, lungs and central nervous system. Amphotericin B deoxycholate is the first choice for treatment and itraconazol considered an alternative.

O objetivo desse estudo é de caracterizar o pescador e a frota pesqueira do Baixo Amazonas. Este estudo está baseado em entrevistas com operadores ou donos de barcos referentes a 3.144 desembarques nos quatro principais portos da cidade de Santarém. Uma análise econômica da atividade desses barcos está baseada em 52 entrevistas conduzidas especificamente para esse fim. Os resultados mostraram que tanto os barcos grandes como os pequenos utilizam, essencialmente, a mesma tecnologia, mas que existem diferenças significativas em termos de estratégias de pesca. Barcos pequenos abastecem o mercado local com captura de uma grande variedade de espécies de peixe. Barcos grandes tendem a se especializar na captura de peixes lisos e, geralmente, abastecem os frigoríficos. Os barcos pequenos são menos eficientes em termos de CPUE (KG/Pescador/Dia), mas eles são economicamente mais eficientes, ganhando mais para cada unidade de dinheiro investido. A maior parte dos barcos que operam em Santarém possui capacidade de gelo abaixo de 4t. Essa categoria de barco é de grande importância para fornecimento de proteína animal, renda e emprego para a região de Santarém.

A febre do dengue é uma das mais importantes arboviroses distribuída por todas as áreas tropicais do mundo. O vírus dengue (VDEN) é transmitido principalmente pela picada do mosquito Aedes aegypti infectado. A dispersão do vetor e o aumento do fluxo migratório entre países possibilitaram a ocorrência de grandes epidemias e manifestações clínicas severas, como febre hemorrágica do dengue (FHD) e Síndrome do choque do dengue (SCD). O objetivo deste trabalho foi realizar a caracterização molecular de isolados do VDEN sorotipo 1 (VDEN-1) no Brasil ao nível dos genes estruturais C/prM/M/E de 29 cepas isoladas durante epidemias ocorridas no Brasil no período de 1994 a 2008. A identidade nucleotídica entre as cepas de VDEN-1 do estudo em relação às outras isoladas no Brasil variou de 96,1% a 100%, enquanto o percentual de identidade de aminoácidos foi determinado entre 98,4% a 100%. As diferenças de aminoácidos entre as cepas do estudo, quando comparadas com a cepa FGA/89 (Guiana Francesa), mostraram a presença de importantes substituições não-sinônimas com mudança de caráter bioquímico, tais como os resíduos E297 (Met Tre) e E338 (Ser Leu), sendo necessário estudos para verificar se essas alterações podem ou não estar relacionadas à virulência. A análise filogenética para a proteína E, realizada por meio do método de máxima verossimilhança para as cepas do estudo e outras cepas selecionadas do banco de dados do Genbank, mostraram que as cepas de VDEN-1 isoladas no Brasil desde 1982 pertencem ao genótipo V, corroborando com os resultados publicados anteriormente. O tempo de divergência do VDEN-1, estimado através da hipótese de relógio molecular, mostrou que este vírus teve sua origem a partir de uma linhagem ancestral, há aproximadamente, 113 anos e observou-se ainda que as cepas de VDEN-1 circulantes no Brasil e as provenientes da África possuem um ancestral comum, sendo necessário estudos de filogeografia que mostrem as possíveis rotas de entrada do VDEN-1 no Brasil.

Forest cover has importance within the context of the water balance of a particular site and may alter the mechanism of entry of water and nutrients to the soil surface. The aim of this study was to quantify the net precipitation, interception, addition of nutrients in throughfall and stem flow in a forest in different stages of regeneration of Mata Atlantica: early-stage secondary forest (ESSF), intermediary stage secondary forest (ISSF) and advanced stage secondary forest (AESF). The study was conducted in Pinheiral, Rio de Janeiro state. The data collection was performed during the period of April 2009 to March 2010. The values of incident precipitation, effective precipitation and interception were similar among the three stages evaluated. The AESF area showed higher values of Mg and P in the addition of nutrients from throughfall compared with other areas assessed. The pH of the precipitation incident did not differ among areas, but was higher than the pH of rainfall. The three areas evaluated showed no difference in the addition of nutrients to flow through the trunk. The AESF area showed a trend of higher levels of addition of nutrients from throughfall precipitation and runoff from stemflow.
