This dissertation aims at analyzing some relations established between teachers‟ formative proposal for docent knowledge and pedagogical practices in the Special Program of Professional Formation to Basic Education (Proformação in Portuguese) with the objective of investigating how teachers evaluate knowledge acquired during their course formation to identify its improvement in their pedagogical practice. This is a Pedagogical Program of the State University of Rio Grande do Norte chosen to be analyzed. The objective is to investigate how teachers, Proformação/Pedagogy course students evaluate privileged knowledge in that university formation and how the relation between this knowledge and their pedagogical practice are experienced in classroom as teachers, defining in which way knowledge constructed and reconstructed during the course contributes for an improvement of their pedagogical practices. We have interviewed fourteen Proformação/Pedagogy last-term teachers, emphasizing the analysis of their point of view as social actors related to docent university formation in service. The principles for this investigation comprehend a qualitative approach, in a case study modality, with an exploratory tendency, presented in the introductory section and along four chapters. The research is theoretically guided by Andoino (1998), Bardin (2009); Laville e Dione (1999); Bogdan and Biklen (1994), Hernandez Sampieri, Hernandez Collado and Baptista Lúcio (2006), among others. We justify this thematic choice, considering docent formation and its interface with an improvement for students‟ leaning, taking into account the strict relations between those elements. We have discussed on docent formative paradigms, based on a multireferential perspective, whose main authors that developed research in this area are: Gómez (1998), Sacristán e Gómez (1998), Tardif (2002), Altet (2001) Paquay e Wagner (2001), Garcia (1999), Baldi (2008), La Torre e Barrios (2002). We interviewed fourteen teachers, all of them in the last term of the Program. In the second chapter, we justify the choice of the subject, approaching docent formation and its relation with basic teaching. We understand that there is a strong relation between those aspects. In the third chapter, we discuss on some docent formative paradigms, among them, Gomes (1998), Sacristán and Gomez (1998), Tardig (2002), Altet (2001) Paquay and Wagner (2001), Garcia (1999), Baldi (2008), La Torre and Barrios (2002). We introduce the Pedagogical Program structure and specify which formative paradigms characterize it and identifying that one of the most prominent paradigm is a practical perspective with emphasis on reflexivity about the practice based on the premise that docent formation is be based on from learning to practice theory. We present an data analysis obtained from thematic categorization extracted subjects‟ discourses and, at the end, we discuss on evaluation of the teachers involved in the research related to the course contributions to provide an improvement for pedagogical practices developed by them inside their classrooms. We consider, thus, that teachers evaluate the Program as a guideline for (re)construction of diversified knowledge, which, in turn, provides the development of abilities to analyze classroom situations based on pedagogical theories and to develop investigative practice based on everyday experience. The results point out that some implications are relevant, among them: the thematic-choice, discussed previously, needs other kinds of investigations. The relation between theory and practice proposed in formation programs requires more systematic studies considering others aspects that characterize teaching process, and mainly, to provide investigative proposals of and about such practices

Esse experimento foi realizado com o objetivo de avaliar a ação de produto de exclusão competitiva (EC) sobre os efeitos da ocratoxina A (OA). As aves alimentadas com 2 ppm de OA na dieta reduziram significativamente o consumo de ração e ganho de peso, além de apresentarem pior conversão alimentar quando comparadas às aves não expostas à OA na dieta. O emprego da EC no primeiro dia de vida não minimizou esses efeitos, bem como não afetou os parâmetros zootécnicos estudados. Aves alimentadas com OA apresentaram diminuição nos títulos vacinais contra o vírus da doença de Newcastle, evidenciando-se assim a interferência dessa micotoxina na resposta imune humoral de frangos de corte. de outra forma, a EC não interferiu na resposta imune humoral de frangos de corte vacinados contra a doença de Newcastle. Tanto a AO como a EC não alteraram os dados de altura de vilo, profundidade de cripta e relação vilo:cripta nas aves aos sete dias de idade quando comparados àqueles do grupo controle na mesma idade

In recent years, the Brazilian construction industry has gone by changes like currency stability, increasing competition, shortage of skilled labor and increasing quality importance required by the customer, who made the sector companies seek solutions through new management practices in order to become more efficient. A alternative to these management practices is known as Lean Construction which is derived from the Toyota System Production. Lean Construction main goals are to reduce parts of activities that do not add value, increase product value by considering customer needs, reduce variability and production cycle time, simplify process by reducing the number of parts or steps, increase the flexibility in the product execution and transparency process, focus the control on overall process, introduce continuous improvement process, maintain a balance between improvements in flows and conversions and seek to learn from practices adopted by competitors. However, the construction industry is characterized by having nomadic activity, which undertakes an unique product with high cost of production and big inertia for behavioral change, making it difficult to implement the philosophy of lean construction in companies. In this sense, the main objective of this study is to develop a methodology for implementation of the principles of Lean Construction. The method of implementing the proposed management system was designed with the aid of 5W2H tool, and the implementation process is divided into three phases. The first one aims to know in a macro way the current operation of construction, identify who is its target audience and what are the products and services offered to the Market. The second phase aims to describe what actions should be taken and which documents are needed to be created or modified; finally, the third step goal consists in how to control and monitor established processes, where through Strategic Planning the company goals would be set along with their respective targets and indicators in order to keep the system working, aiming for continuous improvement with focus on the customer. This methodology was conceived as a case study analyzing a medium size construction with more than 18 years of activity and certified for almost 10 years with ISO9001 and level A in PBQP-H. We also conclude that this implementation process can be used in any developer and / or builder

Telecommunication is one of the most dynamic and strategic areas in the world. Many technological innovations has modified the way information is exchanged. Information and knowledge are now shared in networks. Broadband Internet is the new way of sharing contents and information. This dissertation deals with performance indicators related to maintenance services of telecommunications networks and uses models of multivariate regression to estimate churn, which is the loss of customers to other companies. In a competitive environment, telecommunications companies have devised strategies to minimize the loss of customers. Loosing customers presents a higher cost than obtaining new ones. Corporations have plenty of data stored in a diversity of databases. Usually the data are not explored properly. This work uses the Knowledge Discovery in Databases (KDD) to establish rules and new models to explain how churn, as a dependent variable, are related to a diversity of service indicators, such as time to deploy the service (in hours), time to repair (in hours), and so on. Extraction of meaningful knowledge is, in many cases, a challenge. Models were tested and statistically analyzed. The work also shows results that allows the analysis and identification of which quality services indicators influence the churn. Actions are also proposed to solve, at least in part, this problem

This Master s Thesis proposes the application of Data Envelopment Analysis DEA to evaluate the performance of sales teams, based on a study of their coverage areas. Data was collected from the company contracted to distribute the products in the state of Ceará. Analyses of thirteen sales coverage areas were performed considering first the output-oriented constant return to scale method (CCR-O), then this method with assurance region (AR-O-C) and finally the method of variable returns to scale with assurance region (AR-O-V). The method used in the first approach is shown to be inappropriate for this study, since it inconveniently generates zero-valued weights, allowing that an area under evaluation obtain the maximal score by not producing. Using weight restrictions, through the assurance region methods AR-O-C and AR-O-V, decreasing returns to scale are identified, meaning that the improvement in performance is not proportional to the size of the areas being analyzed. Observing data generated by the analysis, a study is carried out, aiming to design improvement goals for the inefficient areas. Complementing this study, GDP data for each area was compared with scores obtained using AR-O-V analysis. The results presented in this work show that DEA is a useful methodology for assessing sales team performance and that it may contribute to improvements on the quality of the management process.

The Six Sigma methodology has received considerable attention in the last two decades. This is due to its great potencial to reduce processes variability, through the use of accurate data, facts and statistical techniques. The methodology seeks to improve the quality of products and services, maximizing the company s financial performance. Specifically, its implementation and results in medium-sized textile enterprises is unknow, although there are signs that the methodology can be applied with success. Considering this scenario, the goal of this research is to describe the application of the Six Sigma methodology in a médium-sized textile company specialized in the production of male shirts in the satate of Rio Grande do Norte, Brazil. First, we present a literature review, seeking to highlight the themes of quality, Six Sigma and its methodology for improvement. Then, we show the implementation of the project selected, depicting the steps and procedures that must be performed. The results confirm the efficiency of Six Sigma in providing significant gains to companies. It is observed substantial improvements in the speed of product development and the flexibility of the parts produced, reducing the process lead time from 12.5 to 6.2 days, which means a performance improvement of over 50%.

The decrease in crime is one of the core issues that cause concern in society today. This study aims to propose improvements to public safety from the choice of points to the location of police units, ie the points which support the car and the police. For this, three models were developed in order to assist decision making regarding the best placement of these bases. The Model of Police Units Routing has the intention to analyze the current configuration of a given region and develop optimal routes for round preventative. The Model of Allocation and Routing for New Police Units (MARNUP) used the model of facility location called p-median weighted and traveling salesman problem (TSP) combined aiming an ideal setting for regions that do not yet have support points or to assess how far the distribution is present in relation to that found in solution. The Model Redefinition and Routing Unit Police (MRRUP) seek to change the current positioning taking into account the budgetary constraints of the decision maker. To verify the applicability of these models we used data from 602 points to instances of police command that is responsible for the capital city of Natal. The city currently has 31 police units for 36 of these 19 districts and police have some assistance. This reality can lead to higher costs and higher response times for answering emergency calls. The results of the models showed that in an ideal situation it is possible to define a distance of 500 km/round, whereas in this 900 km are covered by approximately round. However, a change from three-point lead reduced to 700 km / round which represents a decrease of 22% in the route. This reduction should help improve response time to emergency care, improving the level of service provided by the increase of solved cases, reducing police shifts and routing preventive patrols

The present work has the objective of presenting an investigation about the quantification, classification and destination of the waste of construction and demolition (RCD) in the city of Natal - RN, focusing the aspects of the environmental impacts and the strategic importance of the environmental administration in the earnings of productivity of the companies. Of the environmental point of view the research intends to identify and to quantify the monthly and annual production of RCD in the city, as well as to know the places of deposition of those residues. To reach the objectives of the study, an exploratory and descriptive research was accomplished, using a questionnaire with closed subjects and an open one, applied in 25 entrepreneurs of the branch of the building site, being 21 builders and 4 entrepreneurs of collection companies and removal dumps. As form of analysis of the data, the descriptive analysis was used and of crossing. The production engineering considers important the insert of best production practices and administration of the product in the companies, with views to the increase of your competitiveness, productivity earnings and improvement of the environmental aspects with views to the consumer's satisfaction, in that case the buyer of immobile. The principal results of the investigation demonstrate that there was not great variability of answers with relationship to the interviewees opinion in what he refers to the environmental practices. In your majority the building site interviewees entrepreneurs evidenced the absence of the public power, particularly the city hall of Natal, in the control, fiscalization and creation of mechanisms for a correct destination of RCD, as well as for your reuse and recycle. On the other hand also it was evident that the recycle or the reuse of RCD on the part of the companies is a rare practice and a lot of times inexistent, although the entrepreneurs' of the building site section great majority recognizes that would have won of productivity with the correct and intensive use of such measures

The jangadas (brazilian fishing rafts) are rudimentary artisanal vessels intrinsic to the Northeast of Brazil. The fishery with jangadas is highly representative in the State of Rio Grande do Norte, and source of income for many families in addition to being a strong cultural icon. Is still alive despite the difficulties, bringing the history and customs of the fishermen and their people. However, is in process of extinction due to factors such as the low profitability of the activity, tourism and urbanization. From the understanding of activity involving their context and circumstances, based on identified problems regarding the conditions of use of jangadas as the unpredictability, the risk of accidents, poor working conditions, hygiene and housing, this dissertation aims to: analyzing the design of the jangada on the beach of Ponta Negra and its relationship with the activity in relation to health, safety, productivity and environment, and from such assessments, together with the results achieved during the workshops of the project, proposing a cart to move the raft, adapted to the local fisherman activity studied. To perform analysis of jangadeira activity, we used a methodology based on ergonomic work analysis - AET (WISNER, 1987; GUÈRIN, 2001; VIDAL, 2008, SALDANHA, 2004 and Carvalho, 2005). For data collection were used observational and interaction methods as a conversational action, verbalizations, photographs and video. It is emphasized that the search for solutions appropriate to the jangadeira activity was possible through the collaboration of several people, not just an informational level and understanding during the work activity, but effectively contributing to the making decisions

The fishing is an activity with rafts marked by unpredictability, poor tools, physical stress, awkward postures, risk of accidents and incidents, which contribute to insecurity in the context of activity. This study aimed to contribute to reducing of physical effort and the biomechanical impacts in jangadeiro activity of artisanal fishing using jangadas on the beach of Ponta Negra, Natal-RN. To achieve this purpose the methodology of the Work Ergonomic Analysis - WEA became a reference using techniques such as observational and interactional observation notes, photographs, videos, action conversational and listening verbalizations. The resulting activity in health jangadeiro, discussed in this research were: static postural assessment, flexibility of movement of shoulder flexion-extension, flexibility of the hamstrings and lower back, grip and musculoskeletal pain. It was found from observations, interactions and activity analysis, that in carrying out fishing rafts are frequent awkward postures associated with demand for power and many are already feeling the jangadeiros reflections of years of life dedicated to this work. These have already adopted some measures to manage the activity, such as job rotation during the expedition of capture. Therefore, there is a need to expand these measures of activity management, as well as design and capabilities of the raft, seeking positive changes in the activity and consequently the quality of life jangadeiro

We have been living in a world of packed products. The package and the labels support the companies to communicate with the customers in addition to give protection, storage and convenience in proportion to the products that move in the price list. The labels mainly add up a value which helps the companies differ their products and increase the value of the brands among the final customers. However, the information given in the label are not clear sometimes. It displays a verbal-visual defective language resulted from a poor visibility, legibleness and comprehensibleness of the verbal and visual marks. The aim of this research is to verify, according to the costumers‟ view, the level of the clarity in the informative texts, harmony and ergonomic conformity of the package labels in the chocolate powder of the Claralate brand, considering the linguistic aspects presented on the labels. The criteria to evaluate the chocolate package selected were based on the linguistic field: the organization and the structure of the text derided from the classification of the textual genre; the clarity and the comprehension of the language utilized on those labels. From the ergonomic view, the informative and ergonomic conformity, based on the following requirements: legibility, symbols, characters, reading fields and intermission of the written lines. Therefore, the research done july 2007 and added july 2011 had a structured questionnaire in the interview put to the 118 customers of the chocolate package that go shopping in one of the two supermarkets in Floriano, Piauí São Jorge and/or Super Quaresma. The main results of the investigation show that the linguistic aspects in the informative texts of the labels provide the customers‟ expectancy partially, while the consideration of the informative ergonomic analyzed can contribute to the improvement of the information and consequent visual progress of those, on the labels of chocolate package investigated. As recommendation towards the maker of the product, the outcome of the research indicates: harmonize the proportion of the letters and numbers; enlarge the letters size; make the visual information more comprehensive determined by the reading field; put the expiry date in a better visual place

The jangadeiros in the work activity are exposed to diverse and constant variability, which are extremely important to know in order to understand this activity and the risks they are exposed. The current study aims to analyze the work activity raftsmen of Ponta Negra beach in Natal, focusing on handling and quality of the fish sold by them to propose through the social construction recommendations for improving its product. To achieve this purpose was used a methodology inspired by the ergonomic work analysis using techniques observational and interactional. He was also made an assessment of fish sold by jangadeiros Ponta Negra, this evaluation was a sensory evaluation using the method "Torry Research" adapted by Vieira (2004) in order to assess the level of quality fish. In general it was observed that the fish originated from the fishing that rafts in Ponta Negra, have a good degree of freshness. But it was found that some ways of handling and storage can be improved
