[pt] A maioria das pesquisas científicas publicadas sobre sequenciamento da produção na indústria automobilística consideram os pedidos já alocados em um dia ou turno de trabalho, desconsiderando especificidades do planejamento da cadeia de suprimentos. Esta dissertação procura contribuir no campo do planejamento da produção, propondo um modelo matemático de programação inteira mista que aborda de maneira integrada dois problemas de otimização fundamentais da cadeia: o problema de seleção de pedidos e o problema de sequenciamento de carros em uma única linha de montagem. A fim de abordar questões bem próximas a realidade, incluindo apresentação de experimentos numéricos com o modelo proposto, utilizou-se como cenário o segmento de caminhões, dentro da indústria automotiva. Considerou-se, como objetivo no modelo, além das abordagens tradicionais (minimizar sobrecarga de trabalho, troca de cores e violação de restrições), a demanda dos clientes com relação a prazos de entrega do pedido – principal reforço para uma indústria que pretende cada vez mais migrar para um ambiente de produção orientado pela demanda. / [en] Most published scientific research on production sequencing in the automotive industry consider orders already allocated in a day or shift, disregarding specificities of supply chain planning. This paper aims to contribute in production planning field, proposing a mathematical model of mixed-integer programming that addresses in a integrated way two fundamental problems from chain: the problem of order selection and car sequencing problem on a single assembly line. In order to approach practical issues, including presentation of numerical experiments from proposed model, the truck segment within the automotive industry was used as scenario. It was considered as objective in the model, beyond traditional approaches (minimize work overload, color changing and violation of restrictions), customer demand with respect promised due dates, the main reinforcement for an industry that increasingly want migrate to a production environment driven by demand.

Abstract When we paint a nebulous future of tomorrow based on the research dictated by the available resources, we see a marathon run for the future that instigates new opportunities for the automotive industry with additive manufacturing. Cars of today are a product of subtractive manufacturing; but in future 3D printing would empower us to define a novel architecture that provokes the construction of the interior, exterior and the powertrain in one piece allowing us to celebrate the marriage between all three key components. Project UNO, meaning - ‘one’, exhibits this new architecture through a semi-autonomous concept that exaggerates the feeling of sportiness with a suspended cabin. In the autonomous mode the cabin moves around in the boundary of the exterior to enhance the g-forces by thrusting the cabin forward while accelerating, backward while braking and tilting while cornering. Therefore, the sporty nature of the design can be celebrated actively in both modes. Inspiration and Method The process was cut up into two palpable routes. The former dealt with a system level approach where the present cardinal building blocks of automotive manufacturing were rearranged with the new cues derived from additive manufacturing techniques to render a new system level solution. The later was aimed at advocating a tangible solution that best delineated this idea. Ten radical themes were generated that helped showcase the marriage between the three key components - exterior, interior and powertrain. The final theme was inspired by the analogy of an egg where the yolk moves freely within the egg white. This metaphor was then applied to the cabin experience in the autonomous mode. The occupant in the manual driven mode can cherish the full potential of the car to procure a sporty experience outside the city. While in the city, the autonomous mode seizes control and instigates the movement of the cabin within the perimeter of the exterior to amplify the g-forces by thrusting the cabin forward while accelerating, backwards while braking and tilting it while cornering. Result Concept UNO celebrates the marriage between the exterior, the interior and the powertrain that best encapsulates the process of additive manufacturing where cars would be grown and not assembled. The interior tub is reposed inside the exterior shell with the aid of six mechanical joints and is not adhered to the floor of the car. The gap around the cabin exaggerates the feel of a floating island that can shift freely. The cabin is composed of smart glass which renders opaque when an electric current is passed through it and turns transparent when the car is parked gravitating people to yield a glimpse of the interior. The bottom of the cabin is reflected by the gloss finish of the chassis unit that amplifies the floating feeling. A warm white was used to grant the concept a more puristic look while making it seem warm and friendly. The idea was then showcased through a 1:4 scale model printed in one piece using a Selective Laser Sintering (SLM) technique.

Student Number : 0215978H - MPh research report - School of Public Health - Faculty of Health Sciences / The study was conducted in the City of Mbabane and assessed Occupational Health and Safety in the informal car maintenance, welding and spray-painting industry. The objective of the study was to assess the risks workers are exposed to in the informal car maintenance, welding and spray-painting industry in Mbabane city in Swaziland. Data was collected by administration of a questionnaire to managers of the establishments and by personal observations of workers while on the job from walk through surveys that were conducted in the city. Seventy (70) workplaces were identified and sixty five (65) of them participated in the study, representing a response rate of 92.86%. There were twenty (20) workplaces doing car maintenance, twenty five (25) doing welding and twenty (20) doing spray painting. Fifty-three (53) The data was analysed using the EPI INFO software and results revealed that most workers in this sector were indeed at high risk of exposure to occupational health and safety problems. They worked under unfavourable conditions such as working in the open and subjected to adverse weather conditions, exposed to solvents, welding fumes and gases, strenuous work, improper postures, lifting heavy loads, exposed to spray painting aerosols and fumes and exposed to dust. The workers’ occupational health and safety was made worse by the fact that most of them did not have or use personal protective equipment. 90% of the workers were exposed to emissions while carrying out their jobs of spray painting and 10% of them were exposed to paint. All the workers that were doing spray painting were exposed to paint (95%) and solvents 5%). Although 75% of the workers, doing spray painting had some kind of personal protection provided however the usage rate was very low. In all the workplaces that were doing spray painting, there were no other existing control measures for protecting the workers from paint emissions 76% did not have any respiratory protection. However, only 33.3% of them were using the PPE provided and 66.7% were not using them. Therefore most of the workers were at risk of breathing in welding fumes and other welding related gases. This means 92 % of workers were at risk to welding fumes and gases. 68% of the workers did not have protection for the hands, only 32% had. Those workers that had hand protection (32%) had gloves with shorter cuffs and separate sleeves (12%). Others had leather gauntlet gloves with canvas or cuffs (20%). 75% of these workers who had PPE were not using them, only 25% did. Since most of the workers did not use hand protection, this means that their hands were not protected against heat, spatter, and radiation. Most of the workers (72%) did not wear eye protection when removing slag and that put them at risk of eye injuries. All welding operations were not done in a booth. This means that the workers and co-workers were at risk of exposure to welding gases and fumes. 48% of the workplaces had their surroundings with materials that could catch fire. 52% had their surroundings free from burnable material. Therefore almost half of the workplaces were at risk of catching fire. 76% of the working places had no fire extinguishers. Only 24% had fire extinguishers, but only two had been serviced accordingly. The workplaces were less prepared for outbreaks of fire. 68% of the workers took no precautions against burns; they had their sleeves rolled up and forearms without gloves or sleeves when carrying out their work. Only 32% of the workers took precautions against burns. 72% of the workers said that they did not know how to treat burns. Only 28% said they knew how to treat them. 72% of the workplaces did not have first aid kits. The means that they were not prepared for accident, only 28% had first aid kits. 71.4% of the work places had first aid kits without the necessary medicines, bandages, and equipment, only 28.6% had. This indicated a lack of preparedness for accidents on their part. A long-term strategy should be developed aimed at improving the occupational health and safety of the workers. Workers need to be empowered to perform their tasks safely. Workers and owners of informal industries should participate in the formulation of interventions aimed at improving occupational health and safety. The City Council should provide health and safety education and training to the Informal Sector.

The project is a vision from the author for future autonomous vehicles in 2030, designed for Volvo. Volvo is one of the pioneering automotive companies for autonomous driving, concerning safety as a priority and taking sustainable responsibility for a better living condition.  In the not too distant future, the author sees people’s perception of mobility will gradually change from traditional private ownership to the ability to move freely. What if a mobility service, coming along with the district you chose to live in, satisfies individual usage needs vary with daily commuting to outdoor trips or moving plans? This type of mobility solution will be ubiquitous, changing the nature of the way people choose to live and move. During the design exploration, the tools varied from ideation sketches, rough package test, photoshop rendering, clay sketching, 3D modelling and experimental display graphic illustrations. This project has been strongly inspired by Scandinavian design and Volvo design principle. Also, the author expressed her vision for Volvo and materials thoughts for components and interior functions. The project outcome is 2030 Volvo Compact Concept, an autonomous sharing and subscription service provided by the residential community.

Embora dietas de alto concentrado sejam comumente utilizadas para acabamento de cordeiros, informações sobre o efeito de teores mínimos de fibra em detergente neutro (FDN) sobre o desempenho de cordeiros são limitadas. O objetivo deste estudo foi avaliar os efeitos da inclusão de baixos teores de FDN em dieta de alto concentrado sobre desempenho, eficiência alimentar, características de carcaça, variáveis sanguíneas e ruminais de cordeiros em terminação. Vinte e quatro cordeiros machos, não castrados (peso vivo inicial de 24,55 ± 2,2 kg) foram distribuídos aleatoriamente em baias individuais, em delineamento inteiramente casualizado, com três tratamentos e oito repetições. Os tratamentos foram teores de FDN na dieta de 15, 20 e 25% com base na matéria seca. As dietas foram compostas de milho, farelo de soja, minerais e silagem de milho, e foram oferecidas duas vezes por dia, com controle diário do alimento ofertado e sobra para determinação da ingestão de matéria seca (IMS). Os animais foram pesados semanalmente e abatidos após 50 dias de confinamento, com peso vivo final de 40,48 ± 2,3 kg. Peso de carcaça quente e fria (PCQ e PCF), bem como o rendimento de carcaça quente e fria (RCQ e RCF) foram medidos. Após a evisceração, foram coletados fluido e conteúdo ruminal para determinação de ácidos graxos de cadeia curta e protozoários. Os dados foram submetidos à análise de regressão, utilizando o pacote estatístico SAS® (versão 9.0, 2002). Cordeiros alimentados com diferentes teores de FDN, apresentaram efeito linear crescente sobre a IMS e o consumo alimentar residual (CAR) conforme aumentou o teor de FDN na dieta. O ganho médio diário (GMD) e as demais variáveis de eficiência alimentar não diferiram estatisticamente entre os tratamentos. Os teores crescentes de FDN na dieta ocasionou diminuição do PCQ, RCQ e RCF, e não houve efeito significativo sobre as demais variáveis de carcaça. As variáveis sanguíneas e ruminais não foram alteradas pelos tratamentos, sugerindo que as dietas utilizadas com alto teor de concentrado e diferentes teores de FDN para cordeiros em terminação proporcionaram homeostase aos animais e ambiente adequado para fermentação ruminal. De modo geral, as dietas com teores baixos de FDN não alteraram o GMD, mas tiveram efeito sobre CAR, peso e rendimentos de carcaça aumentaram e não proporcionaram alterações fisiológicas e ruminais. / Although high concentrate diets are commonly used for finishing lambs, information about the effect of minimum levels of neutral detergent fiber (NDF) on performance is limited. The purpose of this study was to evaluate the effects of increasing dietary fiber levels on performance, feed efficiency and parameters of carcass, blood and rumen of finishing lambs fed high concentrate diet. Twenty four uncastrated male lambs (initial body weight of 24.55 ± 2.2 kg) were randomly assigned to 24 individual pens, in a complete randomized design with three treatments and eight replicates. Treatments were dietary NDF levels of 15, 20 and 25% based on dry matter. Diets were composed of corn, soybean meal, minerals and corn silage, and were offered twice a day with refusals daily measured to determine dry matter intake (DMI). Animals were weighed weekly and slaughtered after 50 d of feedlot, with body weight of 40.48 ± 2.3 kg. Hot and cold carcass weight (HCW and CCW) as well as hot and cold carcass yield (HCY and CCY) were measured. After evisceration, fluid and rumen contents were collected to determine fatty acid short chain and protozoa. Data were submitted to analysis of regression, using the statistical software SAS (version 9.0, 2002). Lambs fed with increasing levels of NDF had a linear efeect on IMS and residual feed intake (RFI). The average daily gain (ADG) and other food efficiency variables were not statistically different between treatments. Increasing levels of NDF in the diet caused a decrease in HCW, HCY and CCY, and there was no significant effect on other carcass variables. Blood and rumen variables were not affected by treatments, suggesting that the diets with high concentrate and different levels of NDF for finishing lambs provided homeostasis animals and adequate environment for rumen fermentation. In general, diets with low NDF did not alter the ADG, but had no effect on RFI, weight and carcass yield increased and did not provide physiological and ruminal changes.

The focus of the thesis is on the informal caregiver and family, who cares for a family member who has had a stroke. This topic is very relevant because CMP is one of the most common causes of disability and death, both in the Czech Republic and worldwide. The thesis consists of theoretical and practical part. The theoretical part is focused on the study of literature and is divided into 4 basic areas. The first area characterizes the concept of brain and stroke, describes the causes, distribution, symptoms, treatment and consequences of this health and life-threatening event. The second area is the division of coordinated rehabilitation, which is necessary after a stroke, whether it be medical, social, pedagogical, work rehabilitation or spa care. The third area focuses on poststroke therapies such as physiotherapy, speech therapy, occupational therapy and psychology. The next area focuses on forms of social assistance, without which home care for a close person would not be possible, and includes a care subsidy, a special aid subsidy, a mobility subsidy, a disability card and pension. Last but not least, terms such as formal and informal care are explained. The method of qualitative research using semi-structured interview technique was chosen for the elaboration of the practical part. The research group consisted of seven members of the South Bohemian Region who take care of a close member of their family for a long time at home. The interviews were recorded and then literally rewritten. In my research, I tried to answer the question: "What are the family's difficulties in caring for family members after having suffered from CMP and what are their most common problems?" In the discussion, I summarized the findings and hypothesised, based on research. The results of the diploma thesis can serve as a source of information for persons after the stroke and thein families and help to educate the public.

É esperado que o consumidor, no momento de decidir qual carro ele irá adquirir, leve em conta, entre diversos outros fatores, a eficiência energética do modelo. Contudo, diversos trabalhos apontam que o consumidor subvaloriza o gasto total que terá com combustível no momento que decide qual modelo de carro irá comprar. Como carros são grandes produtores de externalidades, e por isso, frequentemente são objetos de política pública, é necessário entender esse comportamento do consumidor para que os formuladores o possam levar em conta no momento de fazer as políticas públicas. O objetivo principal desse trabalho ´e estimar o peso relativo que o consumidor brasileiro dá à economia de combustível no momento da escolha da compra do carro, e verificar se, de fato, há uma subvalorização da importância do gasto com combustível no mercado de carros novos no Brasil. Para tentar responder a pergunta proposta serão utilizados duas metodologias distintas. A primeira será uma regressão de preços hedônicos, e a segunda um modelo de demanda aninhado. / It is expected that the consumer, in the moment when deciding which car he will buy, take in account the energetic efficiency of the model. However, many works show that the consumer undervalues the total spent that he will have with fuel in the moment he decides which model to buy. Cars are important externalities creators, and so, are frequently target of public policies, it is necessary to understand this behave of the consumer in order that the policies makers can design the most useful policy. The main objective of this work is to estimate the relative weight that the Brazilian consumer gives to the fuel economy in the moment of the car purchase choice, and verify if indeed, there is a undervaluation of the weight of the fuel spending in the Brazilian new car market. To try to answer this question will be used two different methodologies. The first one is a hedonic prices regression, and the second a nested demand model.

Therefore, the general objective of this dissertation was to explore ?hope? during adolescence. Thus, two studies, a theoretical and an empirical, were conducted in the form of articles. The theoretical article sought, from a systematic review of the literature, to contemplate a general panorama regarding the studies involving the construction of hope in adolescence, aiming to reflect about scientific productions in this area. The studies included in the review englobe the relationship of hope with others constructs, in different countries. The data found point to empirical proposals associating hope with essential virtues for good youth development, demonstrating that this is a promising area for the performance of psychology in Brazil. The empirical article aimed to identify characteristics of hope, religiosity and personality and its relation with drug use in a sample of 668 school adolescents, from 14 to 18 years old, attending to the 8th grade and 9th grade of elementary school and the 3 years of high school in Public schools in a metropolitan city in the southern region of the country. All participants answered a sociodemographic data questionnaire, the Dispositional Scale of Hope, the Duke-Durel Religious Accuracy Scale (P-DUREL), the Drug Use Screening Inventory (DUSI-R), and the Temperament and Character Inventory (TCI). It was found that higher levels of hope are associated with greater non-organizational religiosity and non-use of alcohol. Regarding personality, higher levels of hope was associated with the dimensions of the Self-directedness, Cooperativeness, and Self-Transcendence character. When assessing the final model, hope in adolescents who didn?t use alcohol was better explained by non-organizational religiosity and the personality dimentions Harm Avoidance, Novelty Seeking and Persistence. The findings reveal the importance of studies addressing protective factors for substance use during adolescence, since that period is characterized by exposure and vulnerability to offers and alcohol and other drugs use. / Pesquisas em Psicologia Positiva destacam que for?as humanas, como a esperan?a, operam como amortecedores contra doen?as mentais, sendo determinantes para o desenvolvimento juvenil positivo. Portanto, o objetivo geral desta disserta??o foi explorar o constructo ?esperan?a? no per?odo da adolesc?ncia. Para isso, foram realizados dois estudos, um te?rico e um emp?rico, apresentados na forma de artigos. O artigo te?rico buscou, a partir de uma revis?o sistem?tica da literatura, contemplar um panorama geral a respeito dos estudos envolvendo o constructo da esperan?a na adolesc?ncia, visando a refletir sobre as produ??es cient?ficas nesta ?rea. Os estudos inclu?dos na revis?o abarcaram a rela??o da esperan?a com outros diversos constructos, em diferentes pa?ses. Os dados encontrados apontam propostas emp?ricas associando a esperan?a a virtudes essenciais ao bom desenvolvimento juvenil, demonstrando que esta ? uma ?rea promissora para a atua??o da psicologia no Brasil. O artigo emp?rico teve como objetivo identificar caracter?sticas de esperan?a, religiosidade e personalidade e sua rela??o com uso de drogas em uma amostra de 668 adolescentes de escolas p?blicas de uma cidade metropolitana da regi?o sul do pa?s, com idades entre 14 e 18 anos, pertencentes ? 8? s?rie, ao 9? ano do ensino fundamental, e aos tr?s anos do ensino m?dio. Todos os participantes responderam a um question?rio de dados sociodemogr?ficos, a Escala de Esperan?a Disposicional, a Escala de Religiosidade Duke-Durel (P-DUREL), ao Invent?rio de Triagem do Uso de Drogas (DUSI-R) e ao Invent?rio de Temperamento e Car?ter (ITC-R). Verificou-se que n?veis mais altos de esperan?a se associaram a maior Religiosidade n?o Organizacional e ao n?o uso de ?lcool. Com rela??o ? personalidade, n?veis maiores de esperan?a foram associados ?s dimens?es do car?ter Autodirecionamento, Cooperatividade e Auto-transcend?ncia. A partir do modelo final, a esperan?a nos adolescentes que n?o haviam feito uso de ?lcool foi melhor explicada pela Religiosidade n?o Organizacional e pelas dimens?es da personalidade Evita??o de Danos, Busca por Novidade e Persist?ncia. A partir dos achados, detectou-se a import?ncia de estudos que tenham o objetivo de analisar os fatores protetivos ao uso de subst?ncia na adolesc?ncia, visto que neste per?odo os adolescentes encontram-se mais expostos e vulner?veis ?s ofertas e ao consumo de ?lcool e outras drogas.

Por alimentarem-se diretamente da seiva das plantas, esses cercop?deos causam fitotoxicidade e devido a isso diminuem a produ??o. A modelagem da distribui??o de esp?cies permite analisar a poss?vel occurencia das quatro esp?cies na Am?rica do Sul e Central. Para criar modelos de distribui??o de esp?cies foram utilizados em R, os algoritmos Bioclim, Domain, diferentes modelos lineares generalizados e Maxent.

By direct sap feeding on the plants they cause phytotoxicity and due to this they decrease the production of plantations. With species distribution modeling it is possible to analyze the possible occurence of the four species in South and Central America. To create species distribution models the algorithms Bioclim, Domain, different generalized linear models and Maxent were used in R. For those models current and future bioclimatic variables as well as elevation and other agricultural variables were used. The future climatic variables are for the years 2050 and 2070 with different repentant concentration pathways. The species show suitable habitats in different countries in South and Central America where sugarcane plantations are abundant. The results of the future climate analyzes do not show differences compared to the current climate analyzes. Overall the Maxent algorithm showed the highest AUC scores and Bioclim the lowest. The variables which contributed the most to the models are elevation, isothermality and different precipitation variables. Climate change and therefore additional insect lifecycles do not have an impact on the insect?s suitable habitats. Overall Maxent is the best algorithm to perform species distribution models with a low number of occurrence points and for climate change analyzes.

The theme is the praxis (VAZQUEZ, 1977) of Public Relationships, being delimited by the humanist reading and the educational character, on the assumption that the communication teaching can influence the actions practiced in the professional fiels. Besides this, the area can portray an union between the educational and communicational acts for the society. The main goal is to comprehend the possibilities of an educational character in the Public Relationships praxis, in the humanist perspective of the formation. The theoretical reference covers the praxiological dimension of the academic and professional field, through the Bourdieu Sociology (BOURDIEU, 1983, 1996, 1997, 2007), and considers the contributions of the humanist education, contemplated by the notions of human practice reproduction (BOURDIEU; PASSERON, 2014, the educative act (CABANAS, 1995) and the humanistic formation (FREIRE, 2013). In addition, it discusses different theoretical aspects of the Public Relationships practice: the excellence studies (GRUNIG, 2003, 2011, 2013), the political function (SIM?ES, 1995, 2001, 2009) and the critical and humanistic theory (PERUZZO, 1986, 1998, 2013). Teachers of the activity, that coordinate the Public Relationships graduation courses in Rio Grande do Sul, were consulted for being opinion leaders. The adopted methodological strategy is the hermeneutics in depth (THOMPSON, 1995) and, to achieve an interpretation and reinterpretation, contextualize the doxa by the legislation that regulates the Public Relationships. The socio-historical analysis of the communication teaching (MOURA, 2007; OLIVEIRA, 2007) is added to the Minimum Curricula from 1969 to 1984, in addition to the National Curricular Guidelines (BRASIL, 2002, 2013). For the formal discursive analysis of the statements of the course coordinators, uses the technique of Content Analysis (BARDIN, 1977). The results obtained show that the educational character of the Public Relationships praxis is directly related to its action ? the relationships can be educational acts ? and, potentialized by the humanistic reading, can promote the rethinking of the activity teaching in society. / O estudo apresenta a converg?ncia dos campos da comunica??o e da educa??o (MARTIN-BARBERO, 2014) para compreender a dimens?o de uma pr?tica profissional na sociedade. O tema ? a pr?xis (VAZQUEZ, 1977) de Rela??es P?blicas, sendo delimitado pela leitura humanista e pelo car?ter educativo, e parte do pressuposto de que o ensino da comunica??o pode configurar a atua??o profissional no campo. Al?m disso, a ?rea pode retratar um enlace entre os atos educativos e comunicacionais para a sociedade. O objetivo geral ? compreender as possibilidades de um car?ter educativo na pr?xis de Rela??es P?blicas, na perspectiva humanista da forma??o. O referencial te?rico abrange a dimens?o praxiol?gica do campo acad?mico e profissional, atrav?s da Sociologia de Bourdieu (1983, 1996, 1997, 2007), e reflete sobre as contribui??es da educa??o humanista, contemplado pelas no??es de reprodu??o da pr?tica humana (BOURDIEU; PASSERON, 2014), do ato educativo (CABANAS, 1995) e da forma??o human?stica (FREIRE, 2013). Al?m disso, discute diferentes vertentes te?ricas da pr?tica de Rela??es P?blicas: os estudos da excel?ncia (GRUNIG, 2003, 2011, 2013), a fun??o pol?tica (SIM?ES, 1995, 2001, 2009) e a teoria cr?tica e humanista (PERUZZO, 1986, 1998, 2013). Docentes da atividade, que exercem a coordena??o dos cursos de gradua??o em Rela??es P?blicas no Rio Grande do Sul, foram consultados por serem l?deres de opini?o. A estrat?gia metodol?gica adotada ? a hermen?utica em profundidade (THOMPSON, 1995) e, para atingir uma interpreta??o e reinterpreta??o, contextualiza a doxa pela legisla??o que regulamenta as Rela??es P?blicas. A an?lise s?cio-hist?rica do ensino de comunica??o (MOURA, 2007; OLIVEIRA, 2007) agrega-se aos Curr?culos M?nimos de 1969 a 1984, al?m das Diretrizes Curriculares Nacionais (BRASIL, 2002, 2013). Para a an?lise formal discursiva dos depoimentos dos coordenadores de curso ? utilizada a t?cnica de an?lise de conte?do (BARDIN, 1977). Os resultados obtidos demonstram que o car?ter educativo da pr?xis de Rela??es P?blicas est? diretamente relacionado com a sua atua??o ? os relacionamentos podem ser atos educativos ? e, potencializado pela leitura humanista, podem promover um repensar do ensino da atividade na sociedade.
