Caracterização fisio-molecular de cultivares de feijão (Phaseolus vulgaris L.) em resposta à deficiência hídrica

The identification of genotypes for drought tolerance has a great importance in breeding programs. The aim of this study was to characterize genotypes of beans in response to drought tolerance in different reproductive stages through physiologic, agronomic and molecular analysis. The experiment was conducted in greenhouse, using a randomized block design with four replicates; 10 cultivars: ANFC 9, ANFP 110, BRS Esplendor, BRSMG Realce, IPR Siriri, IPR Tangará, IPR Tuiuiu, IPR Uirapuru, IAC Imperador and IAC Milênio under two conditions of irrigation: plants irrigated during their entire life cycle, and plants under irrigation suppression in the reproductive stage (R7) until 16% of field capacity, when the irrigation was restored. In the last four days of stress, the gas exchanges were analyzed, and in the last day of stress was analyzed the percentage of closed stomata in the abaxial surface of the leaves, collected in different times of the day (9h, 12h, 15h and 18h). Additionally, plant samples were collected for the following analysis: fresh and dry mass of leaves, stems and legumes, and proline content in leaves and roots. The plants were harvested at the physiological maturity and the yield components and grain yield were determined. In addition, in order to identify polymorphisms in the sequences of promoters and genes related to drought, seven pairs of primers were tested on the group of genotypes. The drought susceptibility indexes (ISS) ranged from 0.65 to 1.10 in the group of genotypes, which the lowest values observed were for IAC Imperador (0.65) and BRS Esplendor (0.87), indicating the ability of these two genotypes to maintain grain yield under water stress condition. All genotypes showed reduction in yield components under water stress. IAC Imperador (43.4%) and BRS Esplendor (60.6%) had the lowest reductions in productivity and kept about 50% of the stomata closed during all the different times evaluated at last day of irrigation suppression. IAC Imperador showed greater water use efficiency and CO2 assimilation rate under drought stress. IPR Tuiuiú, IPR Tangará and IAC Imperador had the highest proline concentrations in the roots. Under water stress condition, there was a strong positive correlation (0.696) between the percentage of stomata closed with the number of grains per plant (0.696) and the fresh mass of leaves (0.731), the maximum percentage of stomata closed 73.71% in water stress. The accumulation of proline in the root was the character that most contributed to the divergence between the genotypes under water deficit, but not always the genotypes that have accumulated more proline were the most tolerant. The polymorphisms in DNA of coding and promoting sequences of transcription factors studied in this experiment did not discriminate tolerant genotypes from the sensitive ones to water stress.

Estatística das aplicações de métodos multicritério nas áreas da engenharia de produção

Currently, the decision analysis in production processes involves a level of detail, in which the problem is subdivided to analyze it in terms of different and conflicting points of view. The multi-criteria analysis has been an important tool that helps assertive decisions related to the production process. This process of analysis has been incorporated into various areas of production engineering, by applying multi-criteria methods in solving the problems of the productive sector. This research presents a statistical study on the use of multi-criteria methods in the areas of Production Engineering, where 935 papers were filtered from 20.663 publications in scientific journals, considering a level of the publication quality based on the impact factor published by the JCR between 2010 and 2015. In this work, the descriptive statistics is used to represent some information and statistical analysis on the volume of applications methods. Relevant results were found with respect to the "amount of advanced methods that are being applied and in which areas related to Production Engineering." This information may provide support to researchers when preparing a multi-criteria application, whereupon it will be possible to check in which issues and how often the other authors have used multi-criteria methods.

Proposta de um modelo de gestão de custos para pequenas propriedades rurais familiares com foco na tomada de decisão

This work was general-purpose, develop a proposal of a theoretical model of decisionmaking with a focus on management of small family farms costs, which enables support for decision making. And the following objectives: i) develop a structured methodology, which allows to form a literary basis to provide scientific support for the implementation of research; ii) develop based on the literature the dimensions and variables of the necessary models to propose an application and iii tooling) to implement the proposed model within the dimensions and variables, and validate every stage background and perform the necessary conclusions to verify the effectiveness of applied model. In terms of methodology, we used a structured methodology, which allowed forming a bibliographic portfolio of 29 articles, and through the research constructs developed, based on an existing model, an activity segmentation model for aid farmer of small family farms in the decision-making process with emphasis on cost management. The model was applied in six family farms in the South West region of Parana and Santa Catarina West. With regard to the search results, it was identified that the model can be applied to the specific context for which it was created. It was also possible to identify that the proposed model was valid and relevant to aid in the management of family farms by identifying, through the targeting of productive activities, investment priorities guided by the balance between managing costs and return activities. Moreover, possible to target the activities of six surveyed properties, demonstrating that the property 02, has the shape of more complex segmentation should be divided into three groups of activities, which can be conducted in parallel without any restrictions between activities. Other properties have the segmentation of the simplest activities, allowing viewing in this way that there are activities of groups that require prioritizing investments. Specifically the property 01 and 04 have the highest priority investment target groups, the most prominent activities of groups representing respectively 49.32% and 47.40%, which are represented by grain production activities on the property 01 and grain production, beef cattle and eggs on the property 04.

Arquitetura híbrida com DSP e FPGA para implementação de controladores de filtros ativos de potência

The presence of non-linear loads at a point in the distribution system may deform voltage waveform due to the consumption of non-sinusoidal currents. The use of active power filters allows significant reduction of the harmonic content in the supply current. However, the processing of digital control structures for these filters may require high performance hardware, particularly for reference currents calculation. This work describes the development of hardware structures with high processing capability for application in active power filters. In this sense, it considers an architecture that allows parallel processing using programmable logic devices. The developed structure uses a hybrid model using a DSP and an FPGA. The DSP is used for the acquisition of current and voltage signals, calculation of fundamental current related controllers and PWM generation. The FPGA is used for intensive signal processing, such as the harmonic compensators. In this way, from the experimental analysis, significant reductions of the processing time are achieved when compared to traditional approaches using only DSP. The experimental results validate the designed structure and these results are compared with other ones from architectures reported in the literature.

Formação docente continuada, desenvolvimento de práticas pedagógicas em sala de aula e promoção da saúde do professor: relações necessárias

This article presents an analysis of the results of an action of teacher continuing education in a public Brazilian university. It presents and discusses relations that proved to be necessary between the aforementioned action, the development of classroom pedagogical practices and the promotion of teachers’ health. Its theoretical and methodological foundations consist on a clinic, developmental and dialogic-argumentative character and employ the method of simple and crossed self-confrontation,in order to address professional teaching gestures. The results indicate the necessity of actions related to teachers’ continuing education, focused primarily on the concrete classroom work, which, in addition to allowing the development of pedagogical practices, makes the promotion of teachers’ health itself possible.

Do planejamento ao replanejamento do trabalho docente no ensino superior: o que fazer quando os alunos não leem os textos indicados pelo professor?

The objective of this paper is to present an analysis of the planning and replanning of the teacher´s work in response to difficulties that occur in teacher-student interaction in the process of teaching and learning in and outside the classroom. The data was produced by means of the selfconfrontation method and the analysis is based on theoretical foundations coming from the ergonomics of teaching activity and from the clinic of activity. The results reveal that lack of reading on students´ part leads the teacher to replan the class at the very moment it is taking place, which, in spite of revealing the teacher´s experience with this kind of situation, ends up contributing to diminish the quality of the teaching and learning process.

Elementos sobre o destinatário de emergência em situação de autoconfrontação

This text presents a linguistic, discursive and psychological analysis of modes of manifestation of the phenomenon of emergency addressee in a situation of use of the self-confrontation method in an action of university teacher continuing education. The aforementioned phenomenon consists in the subject seeking to justify and validate his professional individual actions by means of practices which would supposedly be common in his work collective. The self-confrontation method consists in the subject observing himself in a video in which he appears working, with the objective of describing and explaining his activity to a researcher, who acts as a mediator of his subjective development.

Aprendizagem de um gênero de discurso e de atividade de autoconfrontação em ações de formação docente continuada na educação superior

The objective of this text is to discuss a central question in a doctorate study, in progress, about the learning of the speech genre in self-confrontation situations. This consists of a procedure, which a worker observes your own images, video recorded at the time it performs activities related to their craft; It requests that he comment on what he was doing on the images in order to clarify matters for himself and another - be it a intervenant (simple self-confrontation) or a coworker (crossed self-confrotation). (CLOT, 2008/2010). In the context of this research, the confronted workers are university teachers and students who participate in an action of teacher continuing education. The object of the research is the process of speech genre of learning self-confrontation situation, having as subject a person who conducts self-confrontations training, which initially observed the conduct of dialogues and reflections, and will gradually participating in the self-confrontation activity and becoming also forming another. The theoretical foundations of the research seeks an articulation between sciences such as the Psychology of Labor, the Cultural-historical Psychology and Linguistics. The concepts that are employed come from Clot´s theory of the Psychology of Labor, that is, from the Clinic of Activity and from the activity genre studies (CLOT, 2008/2010); they also come from the Vygotskian theory of human development, with the concepts of thinking and speech (VIGOTSKI, 1934/1998); and from the Bakhtinian dialogic principle (BAKHTIN, 1979/2011). We believe that the formation of the person conducting self-confrontation occurs through learning a gender of speech and a genre of activity.

Proposta de avaliação de práticas sustentáveis nas operações de serviço em instituições de ensino superior da Rede Federal de Educação Profissional, Científica e Tecnológica

Higher Education Institutions (HEIs) have an extremely important social role, they are responsible for the place where they work and to form citizens who contribute to a fair and cooperative society. Universities can engage with sustainable development in planning, management, education, research, operations, community services, procurement of materials, transportation and infrastructure; this research seeks to analyze the sustainability practices in service operations in the Higher Education Institutions of the Federal Network of Professional, Scientific and Technological Education in Brazil through the development and application of a model called the Sustainability Assessment for Higher Technological Education (SAHTE). To achieve the proposed goal, a systematic survey of the scientific literature on sustainability assessment models in higher education institutions was conducted, making it possible to identify the characteristics and features of existing models. The model was applied through multiple case studies. The proposal compares the sustainability performance of service operations among individual institutions using a common methodology. It presents five areas to be evaluated in the HEI: Governance and Policies, People, Food, Water and Energy, and Waste and Environment, with a total of 134 questions. The need for greater support from the senior management of institutions to formulate and implement policies on sustainable development was identified when the lack of policies on sustainability in service operations was found; initiatives tend to be isolated. The participation of students and teachers in studies on the daily operations of the campus can be expanded and more widespread. The model seeks to evaluate sustainable practices in the service operations of the Brazilian Federal Network of Professional, Scientific and Technological Education; studies related to the evaluation of teaching sustainability are absent and the applicability of the model in private institutions and other countries is needed. The results obtained with the application of the SAHTE model are useful for the preparation and development of policies on sustainable development, especially in the service operations of the surveyed HEI. The results can sensitize staff and students, who can reflect on their roles in the HEI, as well as the community and suppliers.

Complexos de estudo: investigando um experimento de currículo em uma escola de assentamento do MST no Paraná

The Landless Rural Workers Movement (MST) from its educational process and the path taken in education, started in the year 2013, with an experimental curricular proposal by Complexes of study the School Base and the Itinerant Schools, the MST, in Paraná state. For the construction of this proposed curriculum, the movement takes the historical background and the experience of the original foundations of the single school of labor started by the working class in revolutionary Soviet period as a training proposal and school organization that comes close to the creation of collective subjects, fighters and builders of a new society and sociopolitical objectives to this social movement. The Soviet experiment reference required a work of a critical appropriation for the Brazilian context. The curriculum prescription, called Study Plan, in its introduction, includes elements of design fundamentals like: the Education Eesign and Training Matrix; Matrix detailing: School and Life, School and Labor Formative Matrix, School and Social Struggle Formative Matrix, School and Collective Organization Formative Matrix, School and Culture Formative Matrix and School and History Formative Matrix; general school guidelines: a pedagogical function of the environment, the school's political organization, school times, specific methodological aspects, sequencing and duration of Complexes of Study and the evaluation process. The Study Plan contemplates the complexes, the disciplines, the portions of reality / practice categories present in complexes, organized by semester and year, i. e., from 6th to 9th grade in elementary school. Given the the presented context, this research aims to analyze the process of testing the proposed curriculum for the Complexes of Study in Primary School of Iraci Salette Strozak State School, located in the Marcos Freire Settlement, in Rio Bonito do Iguaçu in Paraná state. As a methodological approach, we chose the qualitative approach and analysis were conducted under the Marxism perspective. Library research and field research, semi-structured interviews and analysis of documents generated in the process of construction of the proposal were made.Initially, in this paper, we discus about the path followed by the MST in the fight for schools and public education; highlighting elements of the process which led to the understanding, by the Movement, of which only the struggle for land is not enough for the realization of Agrarian Reform. Then discuss whether some elements of Pedagogy of the Movement, the concept of education and the goals for education that Social Movement, the training matrices and the potential to transform the school from a pedagogical proposal that has these elements as guiding. They present also the original foundations of Complexes Study in its historical origin and design. Is discussed about the changes and curriculum innovations, curriculum as schooling as social reproduction and presents the structure of Curriculum Proposal by Complex of Study. Forth, it is shown how the experiment occurred in basis School Iraci Salette Strozak. At this point, we propose a dialogue on the transformations in the organization of pedagogical work, discussing the elements of the proposal that are being experienced and the changes already perceived. Still, we address the issue of formation of educators and also elements relating to the challenges andadvancements encountered by the school in this area, and possible implications for the experiment.

Mapeamento projetivo, associação de palavras e escala hedônica como instrumentos de avaliação da percepção de produtos de pescado por crianças da rede pública de ensino

Brazil is a country that is characterized by its low consumption of fish. With consumption records of 10.6 kg/ inhabitant/ year, it is lower than the recommended by the UN, that is 12 kg/ inhabitant/ year. The regular consumption of fish provides health gain for people and their introduction into the school feeding is an important strategy for the insertion of this food consumption habits in a population. In this context, the objective of this study was to understand the perception of fish with children from the public school system through the technical Projective Mapping (MP) and Association of Words (AP); and evaluate the acceptability of fish derivative in school meals. In the first instance with the intention to better understand the perception of children from different ages about the fish-based products, Projective Mapping techniques were applied through the use of food figures and word association. A total of 149 children from three public schools from Pato Branco, Paraná State, Brazil, took part in this study. Three groups of children aged 5-6, 7-8 and 9-10 years old were interviewed individually by six monitors experienced in applied sensory methods. Ten figures with healthy foods drawings (sushi, salad, fruit, fish, chicken), and less healthy foods (pizza, pudding, cake, hamburger, fries) were distributed to the children, who were asked to paste the figures in A3 sheet, so that the products they considered similar stayed near each other, and the ones considered very different stayed apart. After this, the children described the images and the image groups (Ultra Flash Profile). The results revealed that the MP technique was easily operated and understood by all the children and the use of images made its implementation easier. The results analysis also revealed different perceptions came from children from different ages and hedonic perceptions regarding the fish-based products had a greater weight in the percentage from older children. AP technique proved to be an important tool to understand the perception of fish by children, and strengthened the results previously obtained by the MP. In a second step it was evaluated the acceptance of fish burger (tilapia) in school meals. For this task, the school cooks were trained to prepare the hamburgers. For the evaluation of acceptance, the hedonic scale was used with 5 facial ratings (1 = disliked very much to 5 = liked a lot). Students from both genders, between 5 to 10 years old (n = 142) proved the burgers at lunchtime, representing the protein portion of the meal. The tilapia derivative products shown to be foods with important nutritional value and low calorie value. For the application of the multinomial logistic regression analysis there was no significant effect from the age and gender variation in the acceptance by children. However, statistical significance was determined in the interaction between these two variables. With 87 % acceptance rate there was potential for consumption of fish burgers in school meals.

Imperfect indifference : the rhythm, structure and politics of neutrality

Cette thèse propose l’émergence d’une poésie de l’entre deux dans la littérature expérimentale, en suivant ses développements du milieu du vingtième siècle jusqu'au début du vingt-et-unième. Cette notion d’entre-deux poétique se fonde sur une théorie du neutre (Barthes, Blanchot) comme ce qui se situe au delà ou entre l'opposition et la médiation. Le premier chapitre retrace le concept de monotonie dans la théorie esthétique depuis la période romantique où il est vu comme l'antithèse de la variabilité ou tension poétique, jusqu’à l’émergence de l’art conceptuel au vingtième siècle où il se déploie sans interruption. Ce chapitre examine alors la relation de la monotonie à la mélancolie à travers l’analyse de « The Anatomy of Monotony », poème de Wallace Stevens tiré du recueil Harmonium et l’œuvre poétique alphabet de Inger Christensen. Le deuxième chapitre aborde la réalisation d’une poésie de l’entre-deux à travers une analyse de quatre œuvres poétiques qui revisitent l’usage de l’index du livre paratextuel: l’index au long poème “A” de Louis Zukofsky, « Index to Shelley's Death » d’Alan Halsey qui apparait à la fin de l’oeuvre The Text of Shelley's Death, Cinema of the Present de Lisa Robertson, et l’oeuvre multimédia Via de Carolyn Bergvall. Le troisième chapitre retrace la politique de neutralité dans la théorie de la traduction. Face à la logique oppositionnelle de l’original contre la traduction, il propose hypothétiquement la réalisation d’une troisième texte ou « l’entre-deux », qui sert aussi à perturber les récits familiers de l’appropriation, l’absorption et l’assimilation qui effacent la différence du sujet de l’écrit. Il examine l’oeuvre hybride Secession with Insecession de Chus Pato et Erin Moure comme un exemple de poésie de l’entre-deux. A la fois pour Maurice Blanchot et Roland Barthes, le neutre représente un troisième terme potentiel qui défie le paradigme de la pensée oppositionnelle. Pour Blanchot, le neutre est la différence amenée au point de l’indifférence et de l’opacité de la transparence tandis que le désire de Barthes pour le neutre est une utopie lyrique qui se situe au-delà des contraintes de but et de marquage. La conclusion examine comment le neutre correspond au conditions de liberté gouvernant le principe de créativité de la poésie comme l’acte de faire sans intention ni raison.
