Concepções sobre as relações entre ciência, tecnologia, inovação e o desenvolvimento no Proem do Câmpus Cornélio Procópio da UTFPR

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.

Técnicas de manejo agropecuário sustentável

The competitiveness in the rural sector and the need to make viable and sustainable property, direct the farmer to seek new production strategies. In this sense, the book Techniques of sustainable agricultural management has as objective contributed information on concepts, management practices, technological innovations, which are applicable in the agricultural production. The same is composed of 13 chapters, topics covered in aquaculture production, management and dairy production, as general aspects of hematology fish; dynamics of decision-making and adaptive flow dairy production systems; importance of performance measures and body biometrics in small ruminants; milk production in beef cows; parasitism in beef cattle; performance of dairy cows in production; efficiency of cross beef cattle in finishing phase; development of Marchangus: five years; and, bovine growth efficiency. In vegetable production area are addressed matters relating on management and olive cultivation, species of great economic importance and diversification as alternative on the property; functional foods in fruit and vegetables; influence of environmental factors, harvesting and drying in the production and composition of essential oils of Mentha spp; and, implication of the contamination of corn grain by mycotoxins in livestock production. At the end of the book, the expectation of the authors is to have contributed with relevant themes of Brazilian agriculture, which could reflect positively on knowledge, values and quality of available material.

Metodologia participativa para repositórios de recursos educacionais abertos

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.

Características tecnológicas de espécies de pescado com potencial de criação na região sudoeste do Paraná

The fish meat has a particular chemical composition which gives its high nutritional value. However, this food is identified for being highly perishable and this aspect is often named as a barrier to fish consumption. The southwestern Paraná region, parallel to the country's reality, it is characterized by low fish consumption; and one of the strategies aimed at increasing the consumption of this important protein source is encouraging the production of other species besides tilapia. Within this context, it is necessary to know about the meat characteristics. In this sense, the objective of this study was to evaluate the technological potential of pacu, grass carp and catfish species. To do so, at first, it was discussed the chemical and biometric assessment under two distinct descriptive statistical methods, of the three species; and it was also evaluated the discriminating capacity of the study. In a second moment, an evaluation of effects done by two different processes of washing (acid and alkaline) regarding the removal of nitrogen compounds, pigments and the emulsifying ability of the proteins contained in the protein base obtained. Finally, in the third phase, it was aimed to realize the methodology optimization in GC-MS for the analysis geosmin and MIB (2-metilisoborneol) compounds that are responsible for taste/smell of soil and mold in freshwater fish. The results showed a high protein and low lipid content for the three species. The comparison between means and medians revealed symmetry only for protein values and biometric measurements. Lipids, when evaluated only by the means, overestimate the levels for all species. Correlations between body measurements and fillet yield had low correlation, regardless of the species analyzed, and the best prediction equation relates the total weight and fillet weight. The biometric variables were the best discriminating among the species. The evaluation of the washings, it was found that the acidic and basic processes were equally (p ≥ 0.05) efficient (p ≤ 0.05) for the removal of nitrogen compounds on the fish pulps. Regarding the extraction of pigments, a removal efficiency was recorded only for the pacu species, the data were assessed by the parameters L *, a *, b *. When evaluated by the total color difference (ΔE) before and after washing for both processes (acid/alkaline) the ΔE proved feasible perceived by naked eye for all species. The catfish was characterized as the fish that presents the clearest meat with the basic washing considered the most effective in removing pigments for this species. Protein bases obtained by alkaline washes have higher emulsifying capacity (p ≤ 0.05) when compared to unwashed and washed in acid process pulps. The methodology applied for the quantification of MIB and geosmin, allowed to establish that the method of extraction and purification of analytes had low recovery and future studies should be developed for identification and quantification of MIB and geosmin on fish samples.
