This dissertation deals with the conceptions of the relationship between science, technology, innovation, development and society. We aimed to analyze the ways to conceive these relations in documents of the Entrepreneurship and Innovation Programme (Proem) of the Federal Technological University of Paraná (UTFPR) and analyze the conceptions of these relations in view of managers and participants of the Program on Campus Cornélio Procópio, locus of research. It is recognized that the concepts of science, technology, innovation and development are polysemic, so varied are the definitions given by different theorists. For the research were characterized these conceptions into two streams, one called traditional or conservative current, which is supported by the classical theories, that is, those that were developed by authors recognized as classics, and the other current, referred to as critical concepts that sustains it are presented by authors recognized as critical, among which houses the Science studies, Technology and Society (CTS). This categorization buoyed analysis of Proem documents and analysis of the statements collected through interviews with three managers of Proem and eleven participants in the Program. As a result of the research, in general, although there is evidence in Proem documents of a social concern in relation to its role in society, it was observed that the program is based on the traditional and hegemonic view on the subject. In the documents analysis, it was noticed that the conceptions arranged CTS studies are present in relation to the multidimensional development concept. However, the texts analyzed, mostly were identified strong indications of thought supported by logical positivism, in propositions that refer to marketing issues, a proposal to generate an entrepreneurial culture guided by the development of technological innovations designed to meet and / or induce market demands, through production methods for popular goods. As for how managers and participants Proem in Campus Cornelius conceive the relationship between science, technology, innovation, development and society, also was identified closer to the classical view, although the respondents have pointed out many times in their speak apparent concern with social issues, like designing the development from a multidimensional view as cover critical studies CTS. The views of the participants, it was possible to link the strengthening of the concept connected to the linear model of development, in which the more it generates science, more is generated technology and more technology therefore produces more wealth, which in turn, the Schumpeterian view, is the basis of social welfare.

This study focuses on the representations of science and technology in the thinking of the Brazilian intellectual Gustavo Barroso in the period between 1909 and 1935. As one of the main leaders of the Brazilian Integralism, we will discuss,especially, his eugenic vision, prior to his participation in integralism and the influence of this science in building his authoritarian and anti-Semitic thinking. We seek to realize Gustavo Barroso dialogue, in a context of profound social and political changes, with the search for a nationalism "truly Brazilian." The methodology used was of a documentary and literature research , highlighting the analysis of Gustavo Barroso books, which were used as primary sources: Intelligencia das Coisas(1923), Aquém da Atlântida (1931), Brasil Colônia de Banqueiros (1934), O Integralismo de Norte a Sul (1934), O Quarto Império (1935) e A Palavra e o Pensamento Integralista (1935), and, also, some of his articles surveyed in the National History Museum collection. The survey results show that in this period Gustavo Barroso went on to develop in his writings an eugenic and authoritarian political vision, later, in his integralist phase, linked strongly to an anti-Semitic view.

The Brazilian agricultural research agency has, over the years, contributed to solve social problems and to promote new knowledge, incorporating new advances and seeking technological independence of the country, through the transfer of knowledge and technology generated. However, the process of transfering of knowledge and technology has represented a big challenge for public institutions. The Embrapa is the largest and main brazilian agricultural research company, with a staff of 9.790 employees, being 2.440 researchers and an annual budget of R$ 2.52 billion. Operates through 46 decentralized research units, and coordinate of the National Agricultural Research System - SNPA. Considering that technology transfer is the consecration of effort and resources spent for the generation of knowledge and the validity of the research, this work aims to conduct an assessment of the performance of Embrapa Swine and Poultry along the production chain of broilers and propose a technology transfer model for this chain, which can be used by the Public Institutions Research – IPPs. This study is justified by the importance of agricultural research for the country, and the importance of the institution addressed. The methodology used was the case study with a qualitative approach, documentary and bibliographic research and interviews with use of semi-structured questionnaires. The survey was conducted in three stages. In the first stage, there was a diagnosis of the Technology Transfer Process (TT), the contribution of the Embrapa Swine and poultry for the supply chain for broiler. At this stage it was used bibliographical and documentary research and semi- structured interviews with agroindustrial broiler agents, researchers at Embrapa Swine and Poultry, professionals of technology transfer, from the Embrapa and Embrapa Swine and Poultry, managers of technology transfer and researchers from the Agricultural Research Service - ARS. In the second step, a model was developed for the technology transferring poultry process of Embrapa. In this phase, there were made documentary and bibliographic research and analysis of information obtained in the interviews. The third phase was to validate the proposed model in the various sectors of the broilers productive chain. The data show that, although the Embrapa Swine and Poultry develops technologies for broiler production chain, the rate of adoption of these technologies by the chain is very low. It was also diagnosed that there is a gap between the institution and the various links of the chain. It was proposed an observatory mechanism to approximate Embrapa Swine and Poultry and the agents of the broiler chain for identifying and discussing research priorities. The proposed model seeks to improve the interaction between the institution and the chain, in order to identify the chain real research demands and the search and the joint development of solutions for these demands. The proposed TT model was approved by a large majority (96.77%) of the interviewed agents who work in the various links in the chain, as well as by representatives (92%) of the entities linked to this chain. The acceptance of the proposed model demonstrates the willingness of the chain to approach Embrapa Swine and Poultry, and to seek joint solutions to existing problems.

This research deals with the use of a participatory design methodology to develop a repository of open educational resources, the Arcaz. Discusses key aspects of neutrality and determinism of technology within the context of Social Studies of Science and Technology and presents some concepts of critical theory of technology related to the democratic construction of technological artifacts. Discusses the philosophical heritage of the movements that led to the emergence of free software, open education and open educational resources and argues that participatory design share similar ideals. It presents concepts of human-computer interaction, interaction design and user centered design, important to enhance the user experience in information systems. It addresses the participatory design as a methodology that allows the democratic participation of users in the technological construction, promoting mutual learning and active voice for the participants. Develops a participatory design methodology adapted to the Arcaz context of use and provides the procedures for the meetings conducted to apply participatory design techniques to the repository and the results obtained. It concludes with a study of some of the interventions suggested in the system and orientations for future applications of participatory practices in the development of the repository and a list of best practices, focusing on ethical principles that should guide the participatory design.

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