This study has analyzed the high school and professional education policies (1998-2008) and their impacts on the Centro Federal de Educação Tecnológica do Rio Grande do Norte. It has presented an analysis and design of the productive restructuring process in the world of work and education, the technical, vocational education and high school policies in Brazil, referring to this period, as well as the changes in Cefet-RN for implementation of Political Guidelines of Vocational, Technical and High School Education. This study is guided by assumptions related to these policies, which are located in different historical moments. It is a study in which subjects are understood as historical and social beings, embedded in the economic, political and cultural rights which, by its actions, can be transformed. It was based on a theoretical framework consistent with the object of research to give it shape and meaning, serving as a parameter to address the problem outlined in research questions. It was used analysis of bibliographical material and specific documents from the Institution, semi-structured interviews with the subjects part of technical and high school. Results show that many of the recommendations in the present high school policies and vocational technical and high school education, implemented in Cefet-RN, for the period 1998-2002, show inconsistencies between what is said and what can be officially established in the pedagogical practice of teachers and professional practice of some graduates. Regarding the integration of vocational education with the high school (2005-2008) in this Institution, the study signaled that its prioritization failed to materialize in full, in Cefet-RN, although it was developed and implemented a Political-Pedagogical Project in 2005

Neste trabalho, a técnica de PCR (polymerase chain reaction) foi utilizada para a sexagem de 92 embriões bovinos fertilizados in vitro. Os embriões originaram-se de fertilização in vitro de oócitos aspirados de ovários de fêmeas bovinas, provenientes de abatedouros comerciais. Os oócitos foram maturados, fertilizados e cultivados até o estádio de blastocisto. Os embriões foram lavados em solução de PBS, transferidos para tubos de polipropileno contendo água ultrapura, e imediatamente congelados a -196ºC. Os embriões foram descongelados sobre isopor contendo gelo picado e tratados com proteinase K. Para a reação de PCR, utilizaram-se alíquotas de 34 µl de cada tudo, onde foram acrescidos dois pares de primers, seqüência BC1.2 e seqüência satélite 1.715, desoxinucleotídeos, MgCl2, tampão PCR 10X, TaqDNA polimerase e água, em um volume final de 50 µl. As amostras foram amplificadas e a eletroforese realizada em gel de poliacrilamida a 8%. Os géis foram corados com solução de brometo de etídio e analisados em transiluminador de luz ultravioleta. Um índice de 93,47% de amplificação foi atingido, com 41 embriões (47,67%) machos e 45 (52,32%) embriões fêmeas. O uso de gel de poliacrilamida a 8% foi eficaz na separação de fragmentos de DNA muito próximos.

Um estudo foi realizado com o objetivo de avaliar os efeitos do método de remoção da pele do filé (com alicate e com máquina) e da técnica de curtimento (com ou sem sais de cromo, bioleather) sobre a resistência da pele de tilápia-do-nilo (Oreochromis niloticus). Foram retiradas as peles de 40 tilápias (450 g), 20 com uso de alicates e 20 com auxílio de máquina. Após o curtimento e a retirada dos corpos-de-prova, as peles foram encaminhadas a um laboratório aclimatizado (23ºC e 50% de umidade relativa do ar) para realização dos testes de resistência em dinamômetro EMIC, com velocidade de afastamento entre cargas de 100 ± 20 mm/mm. O método de retirada da pele do filé não afetou os resultados dos testes de tração e rasgamento progressivo. A pele retirada com a máquina apresentou elongação superior (88,48%) à removida com alicate (71,09%). Peles curtidas com sais de cromo (25,54 N/mm; 12,18 N/mm²) foram mais resistentes que as curtidas sem sais de cromo (bioleather) (13,11 N/mm; 9,89 N/mm²). Peles curtidas por estas técnicas (com cromo e bioleather) podem ser utilizadas na confecção de vestuários, pois as médias dos testes de tração, alongamento e rasgamento progressivo foram superiores a 9,80 N/mm², 60% e 14,72 N/mm, respectivamente, valores mínimos recomendados para couros curtidos ao cromo.

Analyzes the factors that unleash violence by banalization of the problems and health questions of workers in a federal public institution, in Natal/RN. It analyzes transformations in the world of the work, with its politic, social and economic determinatives and its relation to the worker health. Boarding the violence in the work enviroment and its implications to the worker health, focusing on the banalization of problems faced by the workers as a kind of violence in and with the work. It was chosen an analitic methodology with qualitative approach, through the collection tecnic and information analyzes according to the thematic oral history, with recorders of authorized personal narratives, through individual interview with a semi-structured guide. In the analyzis of results it were made empiric cathegories: the daily work enviroment and its influence to the worker profession and life; the violence presents in the work enviroment and its consequences to the worker life and health; the banalization of the social injustice, due to violence against the worker that broked their dreams concerned to the nursing contribution. The results revealed the ordinary work of these workers showing enviromental and organizational unhealthy conditions, caracterized by physical and tecnical insecurity; absence and disqualification of instrumental and human supplies; overload and complexity service; bad distribution of the duties and pressure to the deadline and productivity, producing tension, conflict and anxiety related to the users, colleagues, superiors and to the duties. In the work enviroment, it were identified a external violence, caracterized by physical and verbal aggresion, psychic suffering, worker depreciation; and internal, caracterized by: moral and psychological molestations and accupational structural violence. These kinds of violence bring consequences to the life, that is, professional, economic and moral order of factors and to the health by biological, mental and emocional factors. The banalization of social injustice during the daily work was discussed in the aspects of banalization of problems and work conditions, the health, qualification banalizations and professional valorization. The workers expectatives pointed out to the necessity of: secure conditions of work; trainning and tecnical assistance; politics of attention to the physical, mental and social health to the workers and their family. We conclude the enviromental and organizational conditions of the workers interviewed do not offer physical and tecnical security that they need to the execution of their activities, neither offer comfort or physical and psychological satisfactions. The politic the instituition has used points out to the depreciation and inhumanization of them producing feelings as unsatisfaction, frustation and indignation related to the institution and the work, bringing suffering and physical and mental sicking. We noticed the most terrible violence found in the work enviroment is the banalization of social injustice related do the problems and health of these workers, producing a slowly debility and simbolic death of their lifes. Therefore, it is necessary the implementation of a politic that promotes assurance, health and integral education, valorization and humanization of these workers

With the trajectory that the problems related to child health are taking in our society, particularly with regard to infant mortality, beyond the process of decentralization of health and the implementation of the Family Health Strategy in the cities, where it has increased considerably performance of nursing staff in Primary Health Care, they can be considered essential factors for reflections on the care of nurse dispenses the health of these children. In order to check how it is organized the working process of the nurse in caring for these children in USFs as well as the difficulties found in the dynamics of this work, this research aimed to analyze the work processes of nurses in care Child Health in USFs, with emphasis on technologies used in producing care. This is a research exploratory and descriptive with qualitative approach, based on the theoretical reference in about Work Process and Composition Technique of Work. The data were collected through semi-structured interviews of 11 nurses who, at the moment, perform their functions for more than 01 year at USF. The guiding questions were based at theoretical reference. To analyze the results, was used the referential of content analysis, and was refer to thematic analysis. In situations that were involved closed questions of the interview, was used the aid of SPSS 15.0 program for Windows. The results indicated that the process of nurse work in health care of children, focuses on the preventive character, whose focus of the actions are healthy children, following the routines and protocols established by the Ministry of Health with a view to maintaining health them. When analyzing the data through theoretical references of Composition Technique of Work found that the core technologies of daily tasks of the nurse are directed for the use of technology soft-hard and hard, and the reason established between the Dead Working and Alive Working, there is prevalence of the first against the second in the production of this care. These situations contribute to the explanation of the emergence problems related to adhesion of mothers / caregivers to monitoring the CD, due to character prescriptive and normalizer of actions. The results also suggested the presence of "vanishing lines" in the make of nurses, confirming the self-governance of health professionals in daily work. These "vanishing lines" express the own execution of the Work Live in action, guided by the use of soft technologies, however, was not characterized as a process of technology transition. So, to get a better resolution to the problems related to child health, the nurse has reorganize your work process by focusing on the execution of work live in action.

The present study is an analysis of interpersonal relationships between the nursing staff and the patients under their care. Its objectives are to analyze ties/links that may possibly exist in such relationships and to describe, based on the experience of the patients, how they are received by the nursing staff, and what is the extent of their reliability on the nursing staff within the hospital. This investigation is analytical in nature and qualitative in approach, having as its leading thought Marcel Mauss s gift-exchange theory. The study involved eighteen in-patients, eight of them from government institutions, at a large hospital school and ten others from a private specialty hospital; both in the city of Natal, state of Rio Grande do Norte, Brazil. Data were collected between January and March 2006. Results point to ties being created between the nursing staff and patients irrespective of their social status, involving especially the development of friendship and reliability. We have noticed that in both services the interpersonal relationship is associated with the circulation of the symbolic goods mentioned in the patients discourse, such as attention, loving care and concern, among others, marking the formation of ties during hospital stay. Likewise, reliability is also present in close relationship with the technical competence of the professional. Patient hospitality is associated with the manner in which the patients were treated on being admitted to the hospital, although they also refer to hospitality at later moments, during the course of their treatment. Finally, we are in a position to say that there are ties/links between in-patients and nursing staff, irrespective of the patient s social status and class divide. It is thus evident that the antiutilitarian symbolism of gift to give, receive, give back -, which shapes the setting of social ties also takes place in today s utilitarian, individualistic and competitive societies. Thus, human beings whose existence is dependent on mutual relationships try to save their humanity, especially those who are fragile and dependent as is the case of the hospital in-patient

O consumo de matéria seca (CMS) de vacas mestiças Holandês-Zebu, fistuladas no rúmen, em lactação, foi medido pela diferença de peso do alimento oferecido e das sobras e estimado com auxílio do óxido crômico (Cr2O3) pela produção fecal (PF) e indigestibilidade do alimento. O delineamento experimental foi em três quadrados latinos (3x3) e os tratamentos consistiram de capim-elefante cortado nas idades de 30, 45 e 60 dias. A digestibilidade in vitro da matéria seca (DIVMS) foi determinada nas amostras do capim-elefante e estimada a partir do consumo medido diretamente e pela produção fecal obtida com o Cr2O3. A produção fecal foi também calculada (PFc) a partir dos valores do consumo (direto) e da DIVMS e foi estimada pela relação do indicador administrado/indicador excretado. Foram observadas diferenças entre os CMS obtidos nas três idades de corte do capim-elefante pelos dois métodos avaliados. Os CMS médios obtidos pelo método direto foram de 8,00; 10,00 e 11,02 kg/vaca/dia, respectivamente, para o capim cortado com 30, 45 e 60 dias. Os CMS estimados com auxílio do Cr2O3 foram de 9,00; 11,10 e 12,00 kg/vaca/dia, para os mesmos tratamentos. As estimativas de consumo utilizando o Cr2O3 foram superestimadas em 9,25% em relação aos resultados obtidos pelo método direto.

Este trabalho foi realizado com o objetivo de determinar a digestibilidade de componentes nutricionais não-degradados no rúmen por meio da técnica de três estádios. Foram avaliados oito alimentos concentrados: grão de girassol integral (GI), torta de girassol com uma (TG1x) e com duas passagens pela prensa (TG2x), grão de soja integral (SI) e parcialmente desengordurado (SD), farelo de soja (FS), farelo de gérmen de milho desengordurado (GM) e concentrado comercial (CC) com 36% de PB. Os alimentos foram incubados no rúmen de bovinos por 33, 20 e 12 horas, correspondendo a taxas de passagens de 3, 5 e 8%/h, respectivamente. Os resíduos não-degradados no rúmen foram submetidos à digestão com solução de pepsina com pH 1,9 durante 1 hora e, posteriormente, em solução de pancreatina com pH 7,8 durante 24 horas, ambas a 38ºC. Nos resíduos desta incubação, foram determinados a MS, MO e os teores de nitrogênio total. A digestibilidade intestinal in vitro da MS não degradada no rúmen, considerando taxa de passagem de 5%/h, variou de 7,88 a 37,72%, sendo que o CC e a SI apresentaram as maiores digestibilidades. A digestibilidade da PB não-degradada no rúmen variou de 13,67 a 81,76% para mesma taxa de passagem. O GI apresentou a menor e o CC e o FS as maiores digestibilidades da PB. A digestibilidade da MO variou de 7,93 a 37,14% para a mesma taxa de passagem, sendo que o GI foi o menos digestível e o CC e a SI, os mais digestíveis. Os menores valores para a proteína digestível não degradável no rúmen (PNDR D), em g/kgMS, foram obtidos nas tortas de girassol com uma ou duas passagens, sugerindo que estes alimentos não devem ser empregados quando se deseja maiores teores de PNDR D.

A modeling of criterias and alternatives is through and applied a questionnaire based on method AHP to proprietors of gas stations. The considered alternatives had been the maintenance of the current state with electric energy of the deliverer and the generation in small scale based on the natural gas. The used criteria had been Cost of the Investment, Final Cost of the Energy, Operational cost, Ambient Benefits, Risk and Variation of Costs. The study it was carried through in the city of Natal, RN in ranks that make use of the natural as for resale, where the generation alternative on the basis of the available gas is present. The main results evidence in a dimension the viability of use of method AHP with questionnaire by means of validation of the judgments with analysis of variance beyond proper the normal mechanisms of analysis of consistency to the method. The main results of the analysis help to show that in this in case that the profile of models of criteria and judgments of the actors is similar, with the final evidence of that it has a dominance of the maintenance of the energy of the deliverer. The main criterion to influence this decision was the risk

The objective of this dissertation is to propose a Multi Criteria Decision Aid Model to be used by the costumers of the travel agencies and help them to choose the best package travel. The main objective is to contribute for the simplification of the travel package decision choice from the identification of the models of values and preference of the customers and applying them to the existing package. It is used the Analytic Hierarchy Process (AHP) method to structuralize a decision hierarchic model composed by six criteria (package cost, hotel category, security of the city, travel time, direct flight and position in ranking of the 10 most visited destination) and five real alternatives of packages for a holiday of three days created from travel agency data. The decision analysis was realized for the choice of a travel package by a group composed by two couples that regularly travels together, to which was asked to do a pairwise judgment of the criteria and the alternatives. The mains results show that, although been a group that travels together, there are different models of values in the weights of the criteria and a certain convergence in the scales of preferences of the alternatives in the criteria. It was not pointed a dominant alternative for all the members of the group separately, but an analysis of a total utility of the group shows a classification and an order of the travel packages and an alternative clearly in front of the others. The sensitivity analysis revels that there are changes in the ranking, but the two alternatives best classified in the normal analysis are the same ones in the sensitivity analysis, although with the positions changed. The analysis also led to a simplification of the process with the exclusion of alternatives dominated for the others ones. As main conclusion, it is evaluated that the model and method suggested allow a simplification of the decision process in the choice of travel packages

This master thesis has the objective of investigating the strategic decision criteria of participants of Local Production Arrangements (LPA) in Brazil. The LPA s are an initiative of support agents to enterprises with the purpose of organizing joint actions for the development of groups (clusters) of enterprises. The choice of the actions is a decision of the participating enterprises and this paper aims at applying a Multi-criteria Analysis Method to analyze the criteria of entrepreneurs that are participating of a LPA. The used method is the Process of Analytical Hierarchy (PAH) and an application is presented along with questionnaires to participants of a ceramic LPA in the northeast of Brazil. The main results show that, in first place, from the implicit strategy of each enterprise there is only one objective for the LPA group and so, at the beginning, an action decided by all of them tends to favor some more than others. In second place, it was observed that there are general inconsistencies between the strategic objectives and the importance as to criteria, even though there have been cases of coherency. As the main conclusion it is pointed that the use of Methods of MCDA is useful to improve the decision making process and to bring more transparency to the logic of the found results

This study evaluates the level of accessibility for people with visual impairment (blindness and low vision) hotels in the city of Natal-RN, Brazil, and provides principles, guidelines and means of projective make hotels accessible, to promote comfort, autonomy and security of these people. We used a qualitative research methodology and quantitative trait descriptive, analytical and interpretive. Was taken as a base for field studies Ergonomic Analysis of Work, beginning with a study of the demands of accessibility of hotels and analyzing the modeling activity in these establishments through the application of interactional and observational techniques, such as film, photographic records, conversational actions and observation protocols. A protocol was developed and applied to evaluate the compliance of accessibility of hotels in the face of Brazilian technical standard NBR 9050 (2004). We used methods of Cognitive Task Analysis (CTA) associated with simulated activities to identify the processes of decision making and analyzing the observables of the activities performed by people with visual impairment (POS). Interviews were conducted with people who are blind and low vision in various cities in order to meet accessibility difficulties they faced in hotels and recommendations for improvement that they indicate. The mapping results showed that of 16 hotels 4 and 5 star studied in Natal-RN, reached only 7% of the 50 items of the protocol, while none of them reached 70% of the items. About the results obtained in simulated activities and analyzed from the ATC, we saw that the hotel where it was performed this step shows a need to adequately address the guests with visual impairments

Creativity is a skill found in all individuals and one of the strategies used to intensify it is through the application of creativity techniques. In order to propose a new technique for generating new crafts product ideas, this dissertation, which is part of a research project of the Federal University of Rio Grande do Norte, through action research, intervened in three state communities artisans - Lajes Pintada, Massaranduba and Vera Cruz - to develop the artisans creative potential. Based on the techniques studied in the literature, we selected three techniques for interventions, composing two dynamics - one to improve features and functionalities of existing products, with the technique of SCAMPER; and the other to generate ideas for creating new products, with techniques Listing and Random Words / Figures. These latter techniques were not satisfactory in its objective by presenting constraints, not covered in the description, for the participant group. Thus, it was necessary to propose a new technique for the same purpose, the technique CREATION Clarify technique, Realized creativity, Explain, Apply for word, Think fast, Interpret, Organize ideas, Now evaluate, composed of twelve steps. To use the new technique requires that it be used by a dynamic that takes into account three phases: Planning, Application and Analysis. In the new technique application were generated around 30 ideas, regarded as new, in six sessions, from test pilot to interventions in artisans communities

This thesis carries through an application of Analysis of Multicriterion Decision with use of the method of Analytical Hierarchy Process (AHP) in the problematic one of taking of decision of the adoption of electronic collecting in the system of urban transport in the country, a subject that has been controversial. A modeling of criteria and alternatives is carried through and applied a questionnaire based on method AHP the excellent actors in the system of urban transport - Leading of the Managing Agency Public Municipal theatre of Urban Transports, Controller of Company of Bus, Controller of Labor union, Controller of Union of Companies, Communitarian Leader. The considered alternatives were: the maintenance of the current state with collectors, the implementation of electronic collection without collectors, and the implementation of electronic collection with collectors. The used criteria were: job, impact in the fare, control of the system, easiness of use, information. The study was carried through in the city of Natal, RN, where if the adoption of electronic collection argues and where this implementation in some bus lines between Natal and Parnamirim exists, city that integrates the region of the great Natal. The main results of the method evidence in a dimension, the viability of use of method AHP with questionnaire by means of validation of the judgments with analysis of variance beyond proper the normal mechanisms of analysis of consistency to the method, and in another one, the contribution of the analysis boarding multicriterion to become the judgments more clearly. The main results of the analysis help to show that although to models of criteria and distinct judgments of the actors, the method evidenced that it has inclination the adoption of the electronic collection on the current situation, even so with divergences between the maintenance or not of the collector. The research points to the possibility of accomplishment of the application of the AHP in successive rounds of judgments
