Maize is one of the most cultivated cereal in the world for its wide range of use in food, feed and industrial use. The production of grain and maize silage in organic system is essencial for the production of organic meat, milk and eggs, because this cereal makes up most of the rations and roughages used in a animal feed The objective was to evaluate the agronomic performance and bromatological parameters of silage of five commercial varieties (AL Avaré, AL Bandeirante, Cativerde 02, AL Piratininga and UFVM 200 - Soberano) and two maize landraces (Santa Rita 1 and Santa Rita 2), in two locations with climatic conditions and different altitudes (Araras / SP, 665 m altitude and Muzambinho / MG, 1100 m altitude) in organic production system. The experiment was carried out in a randomized block design in a 2x7 factorial with four replications. For evaluating the agronomic performance, was measured stalk diameter, plants height, insertion height of the upper ear, leaf number above the upper ear, Falker index of total chlorophyll, leaf nitrogen content, number of rows per ear, number of grain by row and grains per ear, lodging, final stand, 1000 grain weight and productivity. For the evaluation of bromatological parameters of silages was evaluated the productivity of green (GM) and dry matter (DM) and percentage of total dry matter (TDM), acid detergent fiber (ADF), neutral detergent fiber (NDF), crude protein (CP), mineral matter (MM), ether extract (EE), total carbohydrates (CHOT), and non-fiber carbohydrates (NFC) in silage. By results obtained, it was concluded that the agronomic performance of corn grain and the production of green and dry matter silages were influenced by environmental conditions, especially temperature and solar radiation, with better results in Muzambinho. But the environmental conditions not affected the bromatological parameters of silages, which were suitable for all varieties, in both locations. Under the experimental conditions, the landraces showed agronomic performance and bromatological parameters of silage similar to that of commercial varieties in two locations evaluated, indicating that they can be used in commercial crops under organic management.

Hydrogen is considered the energy carrier of the future, due to its high energy content and the possibility of its sustainable production. However, its broader implementation depends on overcoming of several technological challenges, which includes the development of safe and effective storage solutions. In the recent decades, different hydrogen storage materials (HSM) have been investigated for hydrogen storage in the solid state, such as simple hydrides, borohydrides, metalorganic frameworks (MOFs), alanates, intermetallic alloys, ammonia borane, and carbon-based compounds. Technological advances in HSM can be monitored from the patent document analysis applying bibliometrics coupled with text mining. In this study, the stage of the technology life cycle was evaluated, as well as the most prominent HSM and the role of different countries on this subject. Patent data were recovered from the Derwent Innovations Index database (DII), processed in bibliometric software VantagePoint® and used for the preparation of technical indicators. Patents in HSM decreased after 2007, except in China. The territories with more expressive patenting activity were the US, Japan, China and the European Union. Simple hydrides and borohydrides were the main classes for triadic patents in the US and EU, while Japan had a high participation in solid solution alloys. Despite its high number of patent applications, China has no triadic patents on HSM, raising doubts about the technological value of its domestic patents. The life-cycle assessment seems to show that the current stage is between the first prototype experiments in the market and a more spread use of the technologies; however, continued monitoring on the subject is necessary for a more accurate analysis.

Accurate and robust forecasting methods for univariate time series are critical as the historical data can be used in the strategic planning of such future operations as buying and selling to ensure product inventory and meet market demands. In this context, several competitions for time series forecasting have been organized, with the M3-Competition as the largest. As the winner of M3-Competition, the Theta method has attracted attention from researchers for its predictive performance and simplicity. The Theta method is a combination of other methods, which proposes the decomposition of the deseasonalized time series into two other time series called "theta lines". The first completely removes the curvatures of the data, thus accurately estimating the long-term trend. The second doubles the curvatures to better approximate short-term behavior. Several issues have been raised about the Theta method, even by its originators. They include the number of theta lines, their parameters, weights to combine them, and construction of prediction intervals, among others. This doctorate thesis resolves part of these issues. We derive optimal weights for combine the theta lines, this result is used to derive statistical models which generalizes /approximate the standard Theta method. The statistical methodology is considering for parameter estimation and for compute the prediction intervals. The optimal weights are also used to propose new methods that hold two or more theta lines. Part of proposed methodology is implemented in a package for R-programming language. In an empirical investigation using the M3-Competition data set with more than 3000 time series, the proposed methods/models demonstrated significant accuracy. The study’s primary approach, the Dynamic Optimised Theta Model, outperformed all benchmarks methods, constituting, in all likelihood, the highest-performing method for this data set available in the literature.

The Brazilian international image is subject of debate for a long time. It is important to notice that both the official discourse and the way other actors represent a country are relevant for the construction of its image. Among these, the international media has been acquiring an increasingly important role. The purpose of this work is to understand how Brazil was represented and how its images are constructed and deconstructed. With this intent, the British magazine The Economist was chosen as a case study for its relevance in the international arena. Another goal is to inform the political and ideological profile of the magazine and to understand to what extent this influences their coverage. In order to establish a time frame we will analyse the coverage in four different moments: a) the military dictatorship (1964-1984), b) the first governments after democratization (1985-1994), c) Fernando Henrique Cardoso’s government (1995-2002) and d) Luiz Inácio Lula da Silva’s period (2003-2010). To achieve the proposed objectives, editorials, articles and special reports were analysed. The methodology used was content analysis. From the first reading the most significant issues and quotes were divided into themes and sub-themes. It was possible to ascertain that Brazil has always been present among The Economist relevant issues. We could identify that the magazine was more interested in some specific themes and these contributed to the construction of images of Brazil. The political and ideological profile of the magazine ca be identified with two basic ideas: the defence of economic liberalism combined with certain political conservatism. The manner that Brazil was reported and interpreted reflected this position and it can be seen repeatedly. For example: in the defence of the military intervention, the use of Brazil as an example of adherence to free market and the almost absence of criticism for the human rights abuses. On the other hand, debt and inflation appeared to be the elements that headed the criticism. After that, the economic stability and the country emergency were striking images. The Economist seems to maintain an editorial line that subordinates politics to economics and the magazine's profile contributed to construct a more positive or negative image of Brazil depending on domestic and international context.

This research analyzes the work of the operators of a converter substation of electricity from the interior, which can be considered exhausting due to the operating modes that are intrinsic in their daily lives. The objective seeks to identify the impacts caused by organizational changes on the work of people and the system performance due to reduced staff started in 2011. The methodology used was a case study outlined by the Activity Ergonomics of Work. The results indicated that before the staff reduction procedures were performed more safely and accompanied by aspects related to learning issues and recognition of operators. It was concluded that changes in work organization impacted in accelerating the scrapping of the equipment and the precariousness of the work of operators.

Forest inventory is an important tool used to estimate forest wood production. However, some methodologies used in forest inventory are based in Classical Statistics, which disregards any spatial continuity that may exist between sample unities. Some geostatistic interpolators such as ordinary kriging (OK) and external drift kriging (EDK) allow us to assess this spatial structure. Furthermore, besides spatial variability, interpolators as EDK use one or more auxiliary variables. Satellite images have different components that interrelate with dendrometric variables and that can be used as auxiliary variables in order to increase the degree of precision of estimates. The aim of this study was to assess EDK performance on the volume estimation of Eucalyptus sp. stands using satellite image components as secondary variables and to compare it with OK performance. With this purpose, a forest inventory of 210 circular plots of 500 m² was carried out in order to estimate the volume (m³ ha-1 ) in each plot. Images obtained of studied area had blue, green, red and near infrared band. From these bands, it were extracted: gray level in each band, the ratio between bands, vegetation index (NDVI, SAVI e ARVI), texture measures and index generated from textures related to plot area. Covariance model adjustement throughout Stepwise method and selection by AIC (Akaike Information Criterion) method were made to EDK geostatistic. EDK and OK semivariograms were adjusted by different theoretical models through Ordinary Least Squares (OLS) method and the choice of the best model was given by the lowest value of residual standard error. From statistic analysis of images and correlation matrix, it was observed a correlation of variables with volume and also autocorrelation between these variables. The best covariance model selected was composed by band 2, measure of COR texture of band 2, MULCOR texture index of band 1 and by age. In the two semivariograms, the best model adjusted was the exponential one. Analysing the results, volume estimates generated by EDK produced better results than OK estimates and had the lowest value of residual standard error and the best area under curve (AUC) in receiver operating characteristic (ROC) curve analysis.

In order to induce changes in the graduation in Healthcare and to improve the Unified Healthcare System – SUS, the Education Ministry – MEC instituted National Curricular Guidelines – DCN for the fourteen Healthcare related professions. This movement of construction of the DCN is the result of a defense process to educate citizens with a critical view and who agree with the principles and guidelines which SUS preconizes. Therefore, the present study has the goal of analyzing the DCN of the fourteen Healthcare related professions proposed between the period of 2001 and 2004. An exploratory descriptive study has been realized, according to the documental analysis of the DCN, regulated by the Resolution nº287/1998. The data acquiring was realized through the MEC/Portal Site consult, in which were found the resolutions for the fourteen Healthcare related courses. For the proper analysis of the data, an analytic matrix has been used. The matrix contained two axis: Curriculum and Professional Profile, containing the following categories: student evaluation process; teaching-learning process; curricular organization; Professional profile; healthcare; healthcare education and healthcare management. The results reveal gaps related to the articulation of the graduation with the real demands of SUS; there was few focus in innovative concepts, with healthcare perspectives of amplified care; a Professional profile with potent characteristics for SUS establishment; the teaching-learning process shows a initial advance referring to the construction of knowledge centered in the student; the student evaluation that points to a traditional approach. Also, contradictions were verified between conservative and innovative curricular principles; some DCN highlighted technicalist approaches and permissed ambiguous comprehension, showing the lack of clarity to explain the analyzed categories. Considering the DCN as a document that grounds the political pedagogic projects, by ethics, social responsability and commitment. It is expected the ampliation, better explaining and changing in the conservative procedures to seek the promotion, prevention and recuperation and/or rehabilitation, according to SUS statements, throught which the obstacle of integrating teaching, service and social demands will be overcome. Therefore this study proposes the catenation of reflections and possible reviews of the DCN, in the parameters of the Medicine course’s DCN, reviewed in 2014, which brought innovative and significant guiding for a formation directed to the demands of SUS and the needs of the population.

This dissertation comprises four studies that aimed at the establishment of equivalence classes and transfer of functions among stimuli with common class membership with specific reinforcers. In Study 1, seven undergraduates were given to identity MTS training in which movies and tones were applied as arbitrary specific reinforcers. All participants failed on tests for the formation of equivalence classes. Thus, they were not conducted to tests for transfer of functions. Their failures were due to a redundancy of the MTS task for individuals within this population, or to the lack of defined motivational functions of the specific consequences. The nature of the consequences was manipulated in Study 2. This manipulation aimed at guaranteeing that these stimuli would act as reinforcers for six undergraduates within session behavior. The outcomes in two experiments were positive for the establishment and reorganization of equivalence classes and for transfer of functions. These results showed that the failures in Study 1 were due to the arbitrariness of the specific consequences. In Study 3, 10 undergraduates were given to a training comprised by mixed trials of arbitrary and identity MTS with specific consequences. The results on the first experiment were positive for formation and expansion of equivalence classes. Evidences for transfer of functions were also observed. However, nine of these participants had failed in tests for reorganization of the original equivalence classes. Finally, performances by seven participants confirmed that specific consequences can act as nodes for merging stimuli from separate classes. Moreover, further tests were positive for transfer of functions through stimuli within merged classes with specific consequences as nodes. The findings by these four studies for the establishment of equivalence classes and transfer of functions in procedures with different levels of complexity are showing that once class specific consequences had become class members, they will act as nodes as the antecedent stimuli (conditional and discriminative).

In Brazil, there is a growing and promising market that explores the new cultivars of lettuce and crispy segment the Brunella and Crocantella cultivars are examples. The cv. Brunella is an innovative cultivar that combines crisp lettuce characteristics and lettuce being adapted to Brazilian culture conditions. A cv. Crocantella is also included in this segment. It is considered a vigorous lettuce with high numbers of leaves, heavy, thick and light green. The lettuce cultivation may be performed in different cropping systems they are different from each other in crop management and also in post-harvest handling. These differences often produce lettuces with physical, physico-chemical and sensory differentiated. In this way the objective of this study was to determine the effect of different cropping systems in physical, physicochemical and sensory parameters in lettuce cultivars. For cv. Brunella noted that the plant produced hydroponically provided with larger lettuce leaves. The organic plant increased loss of weight. It was not found statistically significant differences for turgor pressure loss analysis among the three cropping systems.The instrumental analysis color demonstrated that hydroponic lettuce presented lighter green that produced the organic system and higher acidity compared to the other two systems. Not found a statistically significant difference in the measurement of soluble solids and total phenolic compounds among the three cropping systems. The sensory analysis cv. Brunella organic was the one with lowest preference and intention to purchase by the consumer. For cv. Crocantella was found that for conventional lettuce leaf area showed higher, then the hydroponic and organic, with significant difference between them. The sample produced in the organic system had lower leaf area, lower ULA and lower initial fresh and even the loss of weight was significantly higher when compared to the other two cropping systems. There was no significant statistical difference in the turgidity initial values, final and loss of turgor pressure between the samples produced in the three cropping systems. In instrumental analysis of color it was also no statistically significant difference among the three cropping systems. The physicochemical analysis was not statistically significant differences in pH values between samples produced in the three cropping systems.The organic sample obtained highest soluble solids, with difference to the hydroponic system. In the determination titratable acidity and total phenolic compounds was obtained statistically significant differences between the three systems. For titratable acidity hydroponic sample had higher acidity, then the organic sample and the conventional sample, for the determination of total phenolic compounds, organic sample had a higher value, then the hydroponic and conventional. With respect to test preference for cv. Crocantela was no statistical difference between the samples produced in the three cropping systems and the purchase intention test, there was significant difference in purchase intent among the samples produced in hydroponic and organic system, that is, the first was most intent the second purchase. It is concluded cultivation system used for the production of lettuce influence on physical characteristics and physico-chemical plants. In this study it was possible to obtain the sensory characterization of Brunella and Crocantella lettuce cultivars. This manner, studies with these characteristics are crucial as they allow the diagnosis of these differences assisting in obtaining important information from production and post-harvest both for the active professional in the field and the consumer.

In technical visits to companies in Marilia and the region, the needs observed; on hiring a professional that would present previous knowledge of galvanization and its applications, it was proposed a reformulation of the menu of the Technological Chemistry discipline in the course of production engineering. This research was applied to the students of 2nd year/4th stage on studying Production Engineering at the Higher Education Institution. The research process involved: a) Utilizing galvanization as the main theme to motivate the learning process of the students; b) Increasing students’ prior knowledge of the galvanization theme; c) Bringing the labor market and the University together through technical visits to the companies of Marilia and the region; d) Proposing additional content to the menu of the Technical Engineering discipline. The exploratory research took a qualitative approach to assist in the collection and analysis of data. Data collection instruments were questionnaires that inquired on prior knowledge and then post-activities. The questionnaires consisted of two phases, one diagnostic and another one for evaluation. In the diagnostic phase, the students answered questions about previous knowledge of Electrochemistry and its applications. The second part of survey was administered after the instruction of new content. Based on the analysis of the answer categories and the correction of assessment tools applied to students, it was possible to observe the improvement in the learning process of the chemistry teaching. During the technical visits were observed the electroplating process for electrowinning and phosphating. The process of galvanizing phosphating is the most widely used in the industries of Marilia and region.

Among the political struggle strategies of the Black Social Movement, which has been characterized by their dynamism and elaboration of each historic moment, thedisputes in the brazilian juridical field can be pointed out, mainly those ones related to the construction of ananti-racism legislation, a set of rules which has a goal of the deconstructingracism, prejudice and social discrimination that cross the brazilian political and social institutions and the subjectivity of the subjects. In this way, according to Discourse Analysis, data analysis method used, and the reflections upon the methodological and theoretical approach of the subaltern studies, particularly the postcolonial studies, I seek to analyze in this reseach the process of construction of this anti-racism legislation/ anti-racial discrimination legislation/anti- discrimination legislation. The specific objectives of the research were, therefore, to analyse: a) which discourses were raised in the normative and juridical field about the racial and ethnic issue making possible the construction of anti-racism legislation from 1950 on; b) which events and debates, ocurred between 1940 and 1988, were outlining the three dimensions of the anti-racism legislation presentin the brazilian legal order, and, finally, c) the importance of Black Movement in this process. The disputes of the normative and juridical field to the construction of the anti- racism legislation and to the deconstruction (still unfinished) of the racial and ethnic relations in Brazil, underlined, on one hand, by an institucional racism and, on the other, by the myth of a racial democracy, represented, at the same time: the problem of brazilian law limits in relation to the racial and ethnic issue, ressignifying, therefore, the own notion of State and brazilian nation; and, a political process in which blacks, being political subjetcs/actors, became subjetcs of rigths, a denied status by brazilian law, during the colonization process and slavery, that marked our history until the 19th century, and still in dispute in the contemporary brazilian society.

The main aims of this work are to study the ways to model mathematically uncertainties using Fuzzy Sets Theory, and then propose a mathematical model to estimate the risk of an individual developing lung cancer through a system based rule fuzzy. Therefore, we consider risk factors, namely smoking, pollution, history of lung disease, family history and contact with chemical agents such as system input variables fuzzy. Lung cancer is a disease that has no symptoms in its early stages, making the diagnosis more difficult to be done and, therefore, most discovered when the cancer is already advanced. This type of cancer is highly lethal and frequent in the population, an increase of 2 % per year in its worldwide incidence.

In this study, hip hop is shown as a culture in permanent movement. The objective of the study is to identify constitutional factors of the hip hop culture. The study design includes field work focusing on female hip hoppers from São Paulo and São Carlos House of Hip Hop institution. Activities from these two groups were observed and the dynamics of the working functionality of the groups were described. There were also descriptions of interactions between different mobilization forms and their influences, performed by the active characters involved in this process. It was observed that the political awareness between the study groups is shaped throughout the characteristics of the speech of the hip hoppers and their practical actions. Therefore, this study concludes that there were two distinct mobilization manners on the way the two groups experience hip hop culture. However, this process is constantly renovated by the interactions and simultaneous affect from between the groups.

We consider the first contribution of an execution of a field work in a school is that students leave their classrooms to study geographical contents, this fact brings an approach between theory and practice. Thus, this teaching methodology allows us to analyze, to question and to problematize the world in spite of the school walls, understanding it like a result of socioeconomic dynamics, conflicts of interests and contradictions wich are part of our reality and influence our experiences and interpretation of what is real. Thus, the use of the field work’s methodology requires not only a teachers planning, but also work conditions that allow teachers remove their students of classrooms and offer them a singular activity that stimulate a meaningful learning. An obstacle to be confronted is the way how Education has been considered by the consumer society guided by neoliberal ideas that have influenced teachers preparing, curriculum materials and educational processes at schools, wich are focused on form technically competent people with specific skills. Although mentioned in Geography National Curricular Parameters like a possibility to build a critical reading about landscapes, the field work is not a priority yet to geography teaching in public schools of São Paulo state, supressing the curriculum. Thus, the general objective of this research was put into operation the execution of field works with students of a public school, thinking about its importance, possibilities, potentialities and limitations, order to establish an interconnected analysis between official documents that concerns the geography teaching in São Paulo state and teachers preparing and conditions. For this pourpose, this study was organized in three steps, as follows: 1) Bibliographic survey, wich in a first moment we could see the importance of a field work to research and geography teaching and, in a second moment we reflect upon the influence of neoliberalism in teachers preparing and in educational processes nowadays, intervening on the performance of field work’s activities at school. 2) Documental research, focused on analysis of PCNs and Oficial Curriculum of São Paulo state, allowing certify the mininal importance given to field investigations activities in geography teaching; and 3) Empirical research, with the establishment of three field work with students from a public school located in Tatuí/SP, making it possible to determine some difficulties for its execution, but a great students feedback as in relation to learning motivation as the way how they built new significances to contents, extending beyond memorization. For analysing the contribution of field work on students learning we consider the precepts of Theory of Meaningful Learning, proposed by David Paul Ausubel, with interpretation of Professor Marco Antônio Moreira.

The computational analysis of human mobility can aid in treatment and rehabilitation of people who have some kind of physical disability. Physiotherapeutic studies, called kinematics, aims to correct body’s dysfunction, caused by genetic malformations, degenerative diseases or posture problems. A computer system can be used to precisely describe motion, anatomical position and angular terms during gait. Therefore, the movements need to be captured and represented in three-dimensional space to be evaluated. This work is a study, development and evaluation of a system for capturing human movement based on recorded videos, using low cost computing resources and adapted to the reality of gait analysis. The automation of computing movements capture, as well as aid in neurological, motor or orthopedic rehabilitation will expand its application to community. In this context, a study was conducted about computing methods of human movements capture by passive markers, and defined the four main steps: calibration and synchronization of the cameras, detection and three-dimensional reconstruction. Computer experiments were made to facilitate the theoretical understanding of this work. Kinematic analyzes data were used as a study case for the implementati

Emotion is an important factor in Human-Computer Interaction (HCI) that influences users’ behavior and satisfaction. Empirical methods, i.e., when users are directly involved, are often applied to assess emotional responses evoked by the user interface, but the cost of data collection and analysis is generally high. The adoption of analytical methods is an alternative to the high cost. Although analytical methods are widely accepted in the HCI area, there is a lack of analytical evaluations for emotional responses. The proposed analytical method in this work adopts the semiotic framework and Peirce’s ten classes of signs for the analysis of the design proposal and by the Scherer’s Semantic Space of Emotions for the association of possible emotional responses evoked by the interface signs. The current version of the proposed method was applied to a case study and results were considered consistent when compared with those obtained through empirical methods.

The fungi of genus Trichoderma are found inhabiting the rhizosphere of plants acting as biological control agents and plant growth promoters. The homeopathic preparations have the potential to assist the vegetative development, promoting adaptation to climate conditions and absorption of nutrients. The interaction between techniques that aim the sustainability of the production system is one of the principles of agroecological view. This study aimed to evaluate the interaction of Trichoderma spp. and homeopathic preparations in vitro and initial development of cherry tomato. The isolates of Trichoderma spp., obtained in the laboratory from soil samples, were subjected to in vitro assays for evaluating the production of indoleacetic acid and phosphate solubilization. The selected isolates were analyzed in relation to mycelial growth, sporulation and germination of spores under the influence of homeopathic treatments (Carbo vegetabilis 6CH and Phosphorus 6CH). In the experiment with cherry tomato, were compared the plant height, stem diameter, fresh and dry shoot, root, leaves and stems, also was determined the leaf area, chemical composition found in the shoot using homeopathic treatments Carbo vegetabilis 6CH and Phosphorus 6CH, such as Trichoderma “F”, “R” and Trichodermil®. The in vitro tests showed that two isolates produced indoleacetic acid and four isolates were higher in phosphate solubilization. It was also observed that Phosphorus increased the speed of mycelial growth of Trichoderma, and positively influenced the sporulation of the isolates. The Carbo vegetabilis treatment provided an increased number of germinated conidia of Trichoderma “F” isolated. In the experiment with cherry tomato it was found that the use of treatments did not influenced on plant height, but it was observed interaction between Trichderma and homeophatic preparations in the increase of diameter stem. It has been found that the use of Trichoderma promoted an increased leaf area index, fresh and dry weight of leaves. The homeopathic treatment Carbo vegetabilis 6CH provided gains on the plant roots. The homeopathic treatments and Trichoderma isolades had influence on cherry tomato above the use of soil nutrients.

The comprehension of the phenomena related to magnetism allowed advances in various fields of knowledge and several modern applications that are now part of our daily lives. Specifically, the magnetic nanoparticles (NPs) has aroused a great interest among researchers in recent decades. This curiosity due to its unique properties is due to its small size and surface interactions. One of the main physical phenomena that appear when we reduce the size of a magnetic particle is called superparamagnetism. In this work, we have looked for a description and understanding of the mathematical formalism attached to magnetic phenomena at nanoscale through the application of the Langevin’s function to magnetic NPs in superparamagnetic regime and non-interacting model. Accordingly, we use theoretical simulations of magnetization curves as a function of applied field to study some parameters and verify its compatibility with magnetic characterization data obtained for samples of NPs magnetite and maghemite. In this way, we can get relevant information to the analysis of the magnetic behavior of nanoparticulate systems. Finally, we have lunched the potential of these magnetic NPs in biomedical applications both in diagnostic techniques and in disease treatments.

Civil construction is one of the activities that generates most jobs in the country, owning handmade construction methods and with few technological innovations. It notes that the number of workers in that area is significant because of the diversity of existing activities in a building. In the case of the reinforcing steel service, tasks are performed manually and request different degrees of effort, which when applied recursively, with tools and equipment unsuitable and inadequate workplace, may cause damage to the health and comfort of workers. In this context, this study aims to evaluate the ergonomic working conditions of the reinforcing steel service. Therefore, we used the methodology of the Ergonomic Assessment Method for Task Analysis (AET), aided by three ergonomic tools: Ergonomic Workplace Analysis (EWA), the Metabolic Equivalent of Task (MET) and the Occupational Repetitive Actions (OCRA). Considering these factors analyzed, with photographic records, interviews and site visiting to watch the worker during his tasks, the actual conditions of the job were studied, trying to analyze everyday work situations, health and safety of workers and featuring, thus, the workplace conditions during reinforcing steel service. The results corroborate the existence of working inadequate postures while performing the task. According to ergonomic tool EWA the most critical ergonomic factor detected was related to Working Postures and Movement, followed by Load Lifting factor. Among the activities analyzed using this ergonomic analysis instrument, the one which presented more critic was related to the assembly of reinforcement for beams. According to the ergonomic analysis instrument MET, tasks with higher energy expenditure and metabolic expenditure were related to Receiving and Storage of steel bars. Among the operation inherent to each task of reinforcement service, there is the tie bars with annealed wire. Finally, it is concluded that the index of exposure OCRA for the activity of tie bars with annealed wire presents imminent risk to all analyzed situations.
