Efeito residual de quatro aplicações anuais de lodo de esgoto e vinhaça na qualidade tecnológica da cana-de-açúcar

O principal objetivo deste trabalho foi avaliar os efeitos residuais, por quatro anos seguidos, de diferentes tipos de resíduos, aplicados de formas e em doses distintas, sobre a qualidade tecnológica da cana-de-açúcar de quinto corte (cultivar SP 81-3250). Os tratamentos testados são combinações de dois tipos de resíduos (lodo de esgoto; vinhaça; lodo de esgoto + vinhaça) com dois modos de aplicação (ao lado da linha de cultivo e em área total) e com duas doses (100 e 200%), e um tratamento-testemunha. O delineamento experimental foi em blocos casualizados, com três repetições, totalizando 39 parcelas. As variáveis analisadas foram: percentagem de sólidos solúveis no caldo extraído (Brix % C.E.), percentagem aparente de sacarose no caldo extraído (Pol % C.E.), percentagem da fibra na cana (Fibra % cana), pureza (%), percentagem aparente de sacarose na cana (Pol % cana), percentagem de açúcares redutores na cana (AR % cana), percentagem de açúcares redutores totais na cana (ART % cana) e açúcares totais recuperáveis (ATR). Os fatores de variação testados (tipo de resíduo, modo de aplicação e doses) não promoveram alterações na qualidade e não comprometeram a valorização da cana-de-açúcar.

Uma contribuição à definição de indicadores de desempenho de instituições federais de educação tecnológica do Brasil na abordagem do balanced scorecard

This Master of Science Thesis deals with a study on applying the BSC Balanced Scorecard to assess the performance of Federal Centers for Technological Education Institution in Brazil, the CEFET s (Centro Federal de Educação Tecnológica), government organizations non for profit. It s accomplished a literature review in order to understand the BSC and its application to non for profit organizations and as a main result it is proposed a BSC conceptual model with an inversion of the main BSC perspective from financial to customer/society. Taking the FORPLAN/CONCEFET performance indicators matrix it is developed a set of performance indicators for the two tops perspective in the conceptual model proposed five for customer/society perspective and three for financial/budget perspective. A field survey with ten CEFET s General Directors is conducted to validate the indicators and assess the perception of the Directors on the hierarchy of the conceptual model, and a hierarchy among the indicators as well. The main results suggests that the indicators are validated, that most of the Directors support the hierarchy presented in the conceptual model but 30% of them have a traditional model with financials coming first. In terms of indicator hierarchy, there s a slight priority for the student unitary cost among the financial perspective indicators, and a relative balance among the customer/society perspective indicators

Fatores de satisfação de empregados: um estudo com docentes de instituição de educação tecnológica

The results suggest an improvement in the model regarding the previous models used by Silva (2003) and Cruz Filho (2007) regarding model explicability of teacher satisfaction

Análise tecnológica sobre os aspectos ambientais de empreendimentos hoteleiros da Praia de Ponta Negra Natal/RN: um modelo de sistema de gestão ambiental

The present work aimed the elaboration of an environmental study focused on the hotel sector in order to present an analysis of the environmental aspects of Ponta Negra Beach, in Natal, RN, Brazil and also the aspects of the small and medium hotels existing in this area. By means of this work, it is possible to elaborate a model of a simplified System of Environmental Management which can attend to the exigencies required by NBR ISO 14001: 2004, as well as to present economical viability and possibility to be implemented in a way that hotels may converge to the sustainable environmental development of the tourism in Ponta Negra Beach. The research methodology presents itself divided into three items: execution of the environmental characterization of Ponta Negra Beach, by way of technical visits and interpretation of satellite images and cartograms of the main environmental characteristics of the region; execution of the work already made concerning the development, application and interpretation of the evaluation of the environmental aspects of each hotel, considering the hotels and the period of data collection, these used in evaluation, research instrument and a description of the procedure utilized for the analysis of the collected data and the utilized methodology for the elaboration of a model of a simplified System of Environmental Management. In a general way, it has been concluded that the practices executed by hotels in Ponta Negra Beach are impact-like and harmful to the environment. The simple implementation of analysis procedures and control of the environmental aspects could suggestively contribute to the reduction of environmental impacts promoted by the hotel section at this beach and in the nearby areas. It had been noticed that the study contributed to the sensitization of managers concerning the environmental problems since, in many other times, the detected problem was, in fact, the non-acquaintance about the environmental aspects and impacts from those hotels administrators, because of the lack of surveys and studies about the theme. It had also been noticed the arousing of a possible environmental attitude from some managers

Avaliação dos indicadores de desempenho de instituições federais de educação tecnológica doBrasil na abordagem do balanced scorecard

This Master of Science Thesis deals with a study on applying the BSC Balanced Scorecard to assess the performance of Federal Institution for Technological Education Institution in Brazil, a government organizations non for profit. It s accomplished a literature review in order to understand the BSC and its application to non for profit organizations and as a main result it is proposed a BSC conceptual model with an inversion of the main BSC perspective from financial to customer/society. It is used the annual management report of thirteen Institutions and applied a Pearson correlation analysis in order to verify a cause-effect situation between indicators. The main findings suggest that the model teachers qualification in terms of degree earned, quantity of teachers in full time job, and rate of students by teacher in full time job having good pearson correlation with the results expected of quality, throughput, social and demand response. However, the student unit cost use as the sole financial indicator did not get any reasonable correlation with the results, as so the quality and quantity of books in the libraries. Although it suggests a need for improvement in the model, the general model adopted appears to be satisfactory as a starting point to a BSC-like performance measuring system to this kind of Institutions

Efeitos do glyphosate e sulfometuron-methyl no crescimento e na qualidade tecnológica da cana-de-açúcar

Os herbicidas, mesmo quando usados em doses reduzidas ou utilizados como maturadores, podem alterar a morfofisiologia da planta, o que pode levar a modificações qualitativas e quantitativas na produção. O presente estudo objetivou avaliar a eficiência agronômica e os efeitos, durante o crescimento da cana-soca, da aplicação de glyphosate e sulfometuron-methyl em baixas doses. O delineamento experimental utilizado foi o de blocos casualizados, com quatro repetições. Os tratamentos foram constituídos pelos herbicidas sulfometuron-methyl e glyphosate em diferentes doses e misturas e por uma testemunha (sem aplicação dos produtos). Uma linha de plantas de cana-de-açúcar foi destinada à aferição da qualidade tecnológica, sendo estabelecido 1 m aleatório a cada época de amostragem. Os colmos coletados foram submetidos ao desponte na altura da gema apical e à desfolha; em seguida, foram encaminhados para processamento segundo a metodologia do Sistema de Pagamento de Cana pelo Teor de Sacarose (SPCTS), sendo considerados os parâmetros tecnológicos: pol cana (PCC), pureza do caldo (PUI), açúcar total recuperável (ATR) e Brix. Nas soqueiras de cana-de-açúcar, realizaram-se análises de crescimento (altura e perfilhos). As avaliações foram realizadas na pré-colheita (30 dias após aplicação dos maturadores) e 30, 60, 90, 120, 150 e 180 dias após a colheita. Os herbicidas glyphosate e sulfometuron-methyl propiciaram melhoria da qualidade tecnológica da matéria-prima,com incrementos significativos na pureza do caldo e no Brix. A aplicação dos produtos não interferiu na produtividade e no teor de açúcar. Houve efeito estimulante no perfilhamento quando se usou glyphosate na dose de 400 mL ha-1 e redução em crescimento (altura) no início do desenvolvimento da cana, porém, com o tempo, o efeito não se manteve.

Caracterização social e tecnológica da produção de uvas para mesa em pequenas propriedades rurais da região de Jales-SP

A viticultura é uma atividade relevante para os produtores rurais do Estado de São Paulo, sobretudo aqueles detentores de pequenas áreas. O presente trabalho teve como objetivo caracterizar os principais aspectos sociais e tecnológicos utilizados na produção de uvas para mesa na região de Jales (SP). Os dados foram levantados nos anos de 2009 e 2010, a partir da aplicação de questionários a 19 produtores de uva e do acompanhamento do ciclo de produção de 10 propriedades. Os produtores cultivam pelo menos três cultivares diferentes de uva, sendo as principais: 'Niagara Rosada', 'Itália' e 'Benitaka'. A área média das propriedades é de, aproximadamente, 21 ha, e a área média com parreiras de uva é de 2,4 ha. A maioria dos produtores não conta com assistência técnica regular, não segue recomendações de adubação e não emprega critérios técnicos para o manejo da irrigação. O controle de doenças é realizado de forma preventiva e intensa, chegando a superar 100 aplicações por ciclo, no caso das uvas finas para mesa. Os resultados devem subsidiar a realização de outras pesquisas, assim como programas de planejamento e transferência de tecnologia, proporcionando ao produtor um manejo mais adequado da cultura, bem como o desenvolvimento sustentável rural regional.

A representação social de educação tecnológica de docentes da Rede Federal de Educação Profissional e Tecnológica: CEFETs do Rio Grande do Norte

The aim of this study was to investigate the social representation of technological education teachers at the Federal Technological Education Network. The survey was conducted from 2007 to 2010, and the respondents were 275 teachers, 135 of the Federal Center for Technological Education (CEFET in portuguese) in the state of Amazonas, in Manaus unit headquarters; 140 of the CEFET in the state of Rio Grande do Norte, a unit based in Natal. We adopt the concept of technological education as the top level of professional education, that is to say, the undergraduate programs of short duration called technological courses. The Federal Technological Education Network gathers hundreds of related institutions, coordinated and supervised by the Office of Vocational and Technological Education of the Ministry of Education. Although many of these institutions offer courses in technology education, no research addressing this subject from the perspective of Social Representations Theory (SRT) was found in the literature. We seek to unravel the social representation of technological education of the teachers by adopting the procedural approach of SRT. This is a qualitative approach, focusing on significant aspects of the representative activity and the formation mechanisms of the representation. Therefore, we search the socio-genesis of the representation in the articulations between discourses, social institutions and practices. We initiated the research through applying critical reading and an analytical perspective on the historical and regulatory documents of technological education in Brazil, from the early twentieth century to the present day. We adopt the Procedure for Multiple Classifications (PMC) from the Free Words Association Technique (FWAT) to access the elements of representational content. For the analysis of the data obtained with FWAT and selection of major words / phrases pertinent to the semantic field of education technology, we used Hamlet II software. For the data analysis of PMC and Free Classification (FC) we used the SPSS ® (Statistical Package for the Social Sciences) version 17.0 and used the method of multidimensional scaling - Multidimensional scaling - (MDS). The output from the central MDS takes the form of a set of scatterplots - "perceptual maps" - of which the points are the elements of the representational content. For the FC data analysis we used the Scalogram Multidimensional Analysis (SMA) - which makes use of the original data in its raw form and allows categorical data to be interpreted in the map as measures of (di)similarity. In order to help with the understanding of the settings of the perceptual maps of FC, we used the Content Analysis of the discourse fragments of the teachers interviewed. The results confirm our initial hypothesis regarding the presence of a single plot among the socio-cognitive study subjects, which is the basis for a social representation of technological education in line with the historic assumption of the dichotomy between mental and manual labor. In spite of the three merging representational elements of the representational content, the perceptual maps compiled from the MSA statistics corroborates the dichotomy, with the exception of the map relating to the subgroup of teachers belonging to the humanities

Produtividade e característica tecnológica de grãos em feijoeiro adubado com nitrogênio e molibdênio

O objetivo deste trabalho foi avaliar o efeito da adubação com nitrogênio e molibdênio, na produtividade e nas características tecnológicas dos grãos de feijão. O delineamento utilizado foi o de blocos ao acaso, em esquema fatorial 4x2, constituído por doses de nitrogênio em cobertura (0, 30, 60 e 120 kg ha-1), aliado à aplicação ou não de molibdênio por via foliar (0 e 80 g ha-1), com quatro repetições. A semeadura do feijão, cultivar Pérola, foi realizada em condições de sequeiro e no sistema de plantio direto. A adubação nitrogenada em cobertura e a molíbdica via foliar não influenciam a produtividade, mas interferem na característica tecnológica dos grãos de feijão. O teor de proteína bruta, o tempo de cozimento e o tempo para a máxima hidratação dos grãos aumentam com as doses de nitrogênio em cobertura. O tempo de cozimento é maior, à medida que há incremento de nitrogênio aplicado em cobertura, com uso de molibdênio via foliar. O uso de molibdênio via foliar proporciona o menor tempo para a máxima hidratação de grãos.
