Soft tissue sarcoma (STS) patients with pulmonary metastases (PM) experience a significant decrease in 5-year survival rates, ranging from 15 % to 50 % compared to 81 % without metastases. Despite this clinical challenge, there is a lack of consensus regarding the optimal treatment approach for PM in STS. To address this, a convolutional neural network (CNN) was developed, utilising transfer learning from a MED3D base model with added custom layers. The CNN aimed to predict surgical treatment response and extract relevant radiological parameters via attribution maps from the CT images of PMs.  The CNN demonstrated promising performance with a balanced distribution of true positive and true negative predictions, giving precision, recall and F1-scores of 0.8. However, the limited size of the data set calls for caution in interpreting the statistical validity of these results.  The evaluation of the attribution maps revealed the classifier assigning significance to regions lacking anatomical relevance, except for one region – the dorsal lobe near a metastasis – showing lower blood vessel density. Nonetheless, no definitive pathological conclusions can be drawn from this observation currently.  In conclusion, this study presents a CNN-based approach for predicting surgical treatment response in STS patients with PMs. However, the small data set warrants further validation and exploration of clinical implications associated with the identified regions of significance.

Detta är en kvalitativ flerfallsstudie som undersökt hur distansarbetet påverkat organisationskulturen hos företag inom IT-branschen. Detta har gjorts på ett abduktivt arbetssätt där teorin har grundat sig Edgar H. Scheins tre nivåer av organisationskultur samt en samling av för- och nackdelar med distansarbete. Empirin har samlats in via sex stycken semistrukturerade intervjuer där intervjuobjekten arbetat på sex olika IT-fokuserade företag. Genom det abduktiva arbetssättet identifierades fem stycken begrepp som vardera beskrev en egenskap inom distansarbetet. Dessutom hittades samband mellan dessa fem begrepp och hur de påverkade de tre nivåerna av organisationskultur. Detta samband kom att illustreras i en egen analysmodell.

The growth of ornamental plant market in Brazil is remarkable nowadays with strong participation of Northeast region, particularly in Alagoas State on the commercialization of tropical flowers. Taking into account this economic aspect, it is of great importance for the productive chain of ornamental species the study of aspects of post harvest activities. Alpinia purpurata (Viell) K. Schum (Zingiberaceae) which occupies the second place in economic importance amongst tropical flowers. It is the main flower for growing and harvesting. The main objective of this research programme is to study the different aspects of Alpinia post-harvesting: (1) time of harvesting and cut of the basis of the stems, and (2) the use of solutions of pulsing ; and/or maintenance of the floral stem by using: (2.1.) biocide compounds and pH of the solution; (2.2) carbohydrates and carbohydrates plus biocides; (2.3) anti-ethylene compounds and antiethylene compounds plus carbohydrates; (2.4) elements as calcium and silicon; and (2.5) senescence retarding growth regulators. It was evaluated the influence of these factors in the water relations, quality and longevity of the stems. Six experiments were carried out in the laboratory (CECA) of the Federal University of Alagoas. In the first experiment, the stems were harvested in three different times and they were cut periodically on their basis. In the second experiment different biocide substances were tested (8- hydroxyquinoline sulphate, aluminum sulphate, salicilic acid and sodium hipocloride) associated to pH variation of the maintenance solution. In the third experiment the stems received sucrose solutions pulsing from 2 to 20% for 12, 24 and 48 hours, following by maintenance in distilled water or in solution of 8- hidroxikinolin (HQS). The fourth experiment comprised three times of exposition (30, 60 and 120 min) with STS 1mM following by the presence or absence of pulsing in sucrose 20% for 12 hours. In the fifth experiment it was evaluated the effect of the addition of Ca (calcium sulphate 50 and 100mM), Si (sodium silicate 1,25 and 2,50 mM) and Ca+Si in maintenance solution. In the sixth experiment the stems were submitted to gibberellins, solutions (GA3), 10, 30 and 60 μm and cytokinin (benzyladenine 6-BA), 10, 20 and 100μm in 24 hours pulsing under continuous light. In all experiments the fresh biomass and the quality (scale of values) of the stems were determined daily or every two days until the end of the experiment. The amount of water was also determined for the floral bracts and dry biomass. The experiments were analised by completely randomized design and the data submitted to the variance analysis, test of averages and , when necessary, to the regression analysis. It was observed that the stems harvested at the end of the afternoon had shown greater commercial value; however, the regular cuts of the basis of the stems reduced their longevity. The use of HQS provided greater durability and humidity of the stems. On the other hand the other biocides did not improve the quality when compared to the control. The reduction of the pH by using citric acid did not interfere with the studied parameters. The use of sucrose in pulsing was only effective when the stems had been kept in distilled water. In this case the concentration sucrose of 20% for 12 hours showed better results. Silver thiosulphate when in pulsing for 30 minutes produced an increase of water contents and for 60 minutes or plus, or when addition of sucrose, caused dehydration of the stems. The only use of calcium sulphate or in association with sodium silicate in maintenance solution caused high improvement of the quality of the stems in comparison to the control and sodium silicate treatment. The use of cytokinin and gibberellins even considering it improved the water contents of the stems did not affect the commercial durability of them. / É notável o crescimento do mercado de plantas ornamentais no Brasil. Com participação efetiva da região Nordeste, destacando-se as exportações de flores tropicais, onde o Estado de Alagoas vem se firmando, com Alpinia purpurata (Viell) K. Schum (Zingiberaceae) como a principal flor de corte, e que ocupa o segundo lugar em importância econômica dentre as flores tropicais. Levando-se em conta esse aspecto econômico, verifica-se ser de grande importância para a cadeia produtiva desses cultivos, o estudo de aspectos relativos à da pós-colheita. Assim sendo, a presente pesquisa, objetivou estudar diferentes aspectos do manejo pós-colheita dessas flores, testando: (1) hora de colheita e corte da base das hastes, e (2) o uso de soluções de pulsing ; e/ou manutenção das hastes florais - neste caso ainda associado (2.1) a substâncias biocidas com o pH na solução sob controle; (2.2) a carboidratos e carboidratos mais biocidas; (2.3) a substâncias anti-etileno e substâncias anti-etileno mais carboidratos; (2.4) a elementos como cálcio e silício; e (2.5) a fitorreguladores retardantes da senescência. Avaliou-se a influência destes fatores nas relações hídricas, qualidade e longevidade das hastes cortadas, através de seis experimentos em laboratório no Centro de Ciências Agrárias da Universidade Federal de Alagoas (CECA/UFAL). No primeiro experimento, as hastes foram colhidas em três diferentes horários, recebendo durante o período pós-colheita cortes periódicos na base da haste. No segundo experimento, foram testadas substâncias biocidas (Sulfato de 8- hidroxiquinolina, Sulfato de alumínio, Ácido salicílico, Hipoclorito de sódio) associadas à redução ou não do pH. No terceiro experimento as hastes receberam tratamento de pulsing com soluções de sacarose entre 2 e 20%, por períodos de 12, 24 e 48 h, seguidas de manutenção em água destilada ou em solução de 8-hidroxiquinolina (HQS) comparando-se com duas testemunhas (água destilada ou solução de HQS). No quarto experimento, foram testados três tempos de exposição (30, 60 e 120 minutos) a STS 1mM, seguido ou não de pulsing em sacarose a 20%, por 12 horas. No quinto experimento, foram verificados os efeitos da adição de Ca (sulfato de cálcio a 50 e 100mM), Si ( silicato de sódio a 1,25 e 2,50 mM) e Ca+Si em solução de manutenção. No sexto experimento, as hastes foram submetidas a soluções de SILVA, A.T.C. 2006 Manejo pós-colheita de alpinia purpurata (Vieill) K. Schum (zingiberaceae)... xv giberelina (GA3), a 10, 30 e 60 μM e citocinina (benziladenina 6-BA), a 10, 20 e 100 μM em pulsing por 24 horas, sob luz contínua. Em todos os experimentos, a massa fresca e a qualidade (com base em notas) das hastes foram determinadas diariamente, ou a cada 2 dias; no final de cada experimento foram também determinados o conteúdo relativo de água das brácteas florais e a massa seca das hastes. O delineamento utilizado foi o inteiramente casualizado sendo os dados submetidos à análise de variância, teste de médias e, quando necessário, à análise de regressão. As hastes cortadas ao final da tarde tiveram maior durabilidade comercial, porém o corte periódico da base das hastes reduziu sua longevidade. O uso de HQS proporcionou maior durabilidade e hidratação das hastes, sendo que os demais biocidas testados não melhoraram a qualidade. A redução do pH, pelo uso do ácido cítrico, não influenciou nas variáveis estudadas. O uso de sacarose em pulsing só foi efetivo quando as hastes foram mantidas em água destilada, sendo melhor o resultado para a concentração de 20% por 12 horas. O tiossulfato de prata em pulsing por 30 minutos, promoveu um aumento de hidratação, mas desidratou as hastes a 60 minutos ou mais ou quando adicionado à sacarose. O uso de sulfato de cálcio em solução de manutenção e quando associado ao silicato de sódio promoveu elevada melhoria de qualidade das hastes. O uso de citocininas e giberelinas embora tenha melhorado as relações hídricas das hastes não afetou a durabilidade comercial das mesmas.

Ce travail de thèse s’est inscrit dans un cadre fondamental d’étude de la formation contrôlée d’oxydes en couches ultra-minces. Un bâti ultra-vide dédié à la croissance contrôlée de ces oxydes et à leur analyse in-situ (STM-STS, AES et LEED) a été développé. Par une méthode originale de phases alternées de dépôt d’une monocouche atomique de Mg et oxydation à RT, les mécanismes impliqués dans la formation de deux systèmes à fort potentiel applicatif : MgO/Si(100) et MgO/Ag(111) ont été étudiés .Le système MgO/Si(100) a révélé la formation d’une couche ultra-mince de Mg2Si à l’interface entre le MgO et le substrat. En bon accord avec les calculs thermodynamiques réalisés, une cristallisation de cette couche interfaciale dans un processus de dissociation partielle du Mg2Si en MgO à température ambiante a été observée. Identifiée ex-situ par TEM, la relation d’épitaxie associée à cette cristallisation a permis de conclure à la formation d’une hétérostructure MgO / Mg2Si (11-1) / Si(001), témoignant d’une grande qualité d’interface avec le silicium et de la formation d’une couche ultra-mince et amorphe de MgO homogène et isolante (gap de 6 eV).Pour le système MgO/Ag(111), nos résultats expérimentaux couplés aux calculs ab initio de nos partenaires du LAAS ont révélé l’absence de formation d’un alliage de surface ainsi qu’une croissance « liquid-like » du magnésium à RT. Un double empilement O/Mg/O/Mg/Ag(111) suivi d’un recuit UHV à 430°C a ensuite permis la stabilisation d’une couche ultra-mince polaire de MgO(111) qui a été caractérisée par LEED et STM-STS. Les propriétés physico-chimiques et origines possibles de stabilité de cet oxyde polaire ont ensuite été discutées. / This PhD work was dedicated to studying the fundamental mechanisms driving the controlled growth of ultra-thin oxide films. An experimental set-up was designed to finely control the growth parameters under UHV conditions while allowing the study of such oxide layers in situ with STM-STS, AES and LEED. Using an original method based on alternate cycles of Mg monolayer adsorption and RT oxidation, we focused on the formation of systems exhibiting a wide range of potential applications: MgO/Si(100) and MgO/Ag(111). The MgO/Si(100) system revealed the growth of an ultra-thin Mg2Si layer at the interface between the MgO and the silicon. In agreement with thermodynamic calculations, a crystallization of this interlayer driven by a partial decomposition of the Mg2Si to a MgO oxide was shown to occur at RT. From ex situ TEM experiments, the involved epitaxial relationship highlighted the formation of an MgO / Mg2Si (11-1) / Si(001) heterostructure. A sharp interface with the silicon was formed, as much as an ultra-thin and amorphous MgO layer exhibiting both a good homogeneity and a high insulating character (bandgap of 6 eV).In the MgO/Ag(111) system, no interfacial alloy formation and a « liquid-like » growth for the Mg were evidenced at RT, using our experimental results coupled with the ab initio calculations performed by our co-workers at LAAS laboratory. Later, a double-layering O/Mg/O/Mg/Ag(111) grown at RT followed by UHV annealing at 430°C resulted in the stabilization of a polar MgO(111) ultra-thin film, which was characterized using LEED and STM-STS. The physicochemical properties of this polar oxide and the potential origin of its stability were discussed.

In der hier vorliegenden Promotionsschrift wird ein von der Akteur-Netzwerk-Theorie inspirierter ethnographischer Forschungsansatz angewandt, um, ausgehend von dem Setting des Studiokurses an einer spanischen Architekturschule, aufzuzeigen, wie Architekt:innen die disziplinären Logiken der Architekturausbildung und in weiterer Instanz die Schnittstelle zwischen Ausbildung und professioneller Praxis problematisieren und aus der Disziplin selbst heraus neu verhandeln. Hierbei wird beschrieben, (1) wie die Einheit von Architekturausbildung und der Bauwelt/Baupraxis aufgebrochen wird, (2) wie der Begriff des Grundproblems in der architektonischen Gestaltung selbst problematisiert wird und, (3) wie in der architektonischen Produktion, (lokale) sozio-politische Themen, die agency von nicht-menschlichen Akteur:innen und die ethische Verantwortlichkeit von Architekt:innen für die gebaute Umwelt, neue Relevanz gewinnen. Basierend auf einer ethnographischen Feldforschung (zwischen 2017-2019), wird in dieser Dissertation eine neue Konzeptualisierung von Architektur vorgestellt: die ‚Architektur als theoretische Praxis‘. Diese eröffnet neben der ‚Architektur als Form‘ und der ‚Architektur als Entwurfspraxis‘ eine weitere Betrachtungsebene von Architektur, welche es ermöglicht die architektonische Produktion jenseits des Entwurfs von Gebäuden und Bauelementen zu untersuchen und aufzuzeigen, wie Architekt:innen in Gestaltungsprozessen Konzepte und Diskurse selbst bauen und so als Teil ihrer sozio-materiellen Praktiken umsetzen. Dadurch werden Parallelen zwischen der Akteur-Netzwerk-Theorie und der ‚Architektur als theoretische Praxis‘ diskutiert und aufgezeigt, wie beide als (unterschiedliche) Formen einer „Anti-Theorie“ definiert werden können. / This dissertation explores from an actor-network theory inspired ethnographic research approach how architects do, challenge and problematize the disciplinary logics of architectural education and, in a further instance, the intersection between architectural training and the professional practice. Taking the studio courses at a Spanish architecture school as starting point, this ethnographic case study describes (1) how the unity of architectural education and building practices is suspended, (2) how the concept of the fundamental problem in architecture is problematized by architectural design practices, and (3) how (local) socio-political issues, the agency of non-humans and the ethical accountability of architects for the built environment gain new relevance in architectural production. Based in ethnography research (between 2017-2019), this dissertation presents a new conceptualization of architecture: the ‘architecture as theoretical practice’. In comparison to an ‘architecture as form’ and an ‘architecture as design practice’, this new conceptualization opens up the possibility to examine architectural production beyond the design and construction of buildings and reveals how architects build or materialize concepts and discourse as part of their socio-material practices. Consequently, parallels between actor-network theory and 'architecture as theoretical practice' are discussed by showing how both of them can be defined as (different) forms of ‘anti-theory’.

I föreliggande avhandling undersöker Hultman hur bränsleceller och vätgas underolika tidpunkter beskrivits som delar i ett framtida energisystem 1978 – 2005. Detempiriska materialet som analyseras är statliga utredningar, böcker, rapporter,tidningsartiklar och riksdagstryck. Syftet är att undersöka vilka aktörer sombeskrev tekniken, på vilket sätt tekniken konstruerades samt hur dessa förflyttadesoch förändrades under olika tidsperioder. Avhandlingens empiri undersökstillsammans med teorier om utopier och förväntningar på teknik samt tidigareforskning om svensk energi- och miljöpolitik. Avhandlingen är indelad i kronologiskt strukturerade kapitel vilka länkas sammanav analytiska platåer. I slutkapitlet diskuteras resultaten av den historiskaförändringen från visionerna om vätgassamhällen till en vätgasekonomi i treteman. Inom det första temat analyseras omdaningar över tid med fokus påaktörer, argument och teknik. I det andra temat fokuseras hur föreställningar omtekniken byggdes upp till nya höjder mellan 2000-2005. Bland annat diskuterashur tekniska, ekonomiska, miljörelaterade och säkerhetsmässiga förväntningarskapades med hjälp av starka metaforer som vatten, vägkartan och marknaden.Dessa förväntningar gjordes på olika platser och lånades mellan lokaliteter. I dettredje temat diskuteras vätgasekonomin som en ekologiskt modern utopi. I ensådan extrapoleras framtiden utifrån en ökning i takten av teknikförändringarna,men samtidigt ska samhällsstrukturerna konserveras. / At the turn of the millennium, high expectations were connected to a technologycalled fuel cells. It was said that it could contribute in a significant way to solvingthe problem of increasing greenhouse gas concentrations in the atmosphere andreverse the greenhouse effect. But this was not the first time fuel cells andhydrogen has been described as a technology for the future and connected todifferent kind of utopias. On the contrary, this technology has a history ofexpectations connected to it and in this dissertation the period 1978 – 2005 isanalysed with focus on reoccurring arguments, main actors and how descriptionsof expectations move between different locations and different periods of time.These questions are answered with an analysis of empirical material that containsgovernmental reports, mass media articles, scientific reports as well as field notesfrom an participatory study. In this dissertation the analysis is read together withprevious research regarding Swedish energy- and environmental politics as wellas international research about fuel cell and hydrogen. The investigation is alsoinformed by theories about utopia and sociology of expectations. The main conclusion to be drawn from the historical period 1978 – 2005 is thatthe utopia hydrogen and fuel cells are said to be parts of change, from differentpossible hydrogen societies to one hydrogen economy. This change can beexemplified with changing roles of science, technology and the state as well ashow former environmental activists and political parties change their values.

Trotz einer Vielzahl von Forschungsarbeiten auf dem Gebiet der Phthalocyanin-basierten organischen Verbindungen fehlt nach wie vor ein umfassendes Verständnis des Zusammenspiels zwischen strukturellen und elektronischen Eigenschaften, die sich bei der Abscheidung dieser Stoffe auf anorganische kristallinen Substraten ausbilden. Vor diesem Hintergrund wurden für die vorliegende Arbeit vier metallbasierte Phthalocyanine ausgewählt und mittels organischer Molekularstrahl-Abscheidung (OMBD) im Ultrahochvakuum (UHV) auf Ag (111) Einkristalle adsorbiert. Für die anschließende eingehende Untersuchung dieser Proben wurden insbesondere Rastertunnelmikroskopie (STM) und -spektroskopie (STS) angewandt. Ergänzend kamen Ultraviolett- und Röntgen-Photoelektronenspektroskopie (UPS und XPS) zum Einsatz, wodurch komplementäre Informationen gewonnen wurden. Die aus diesen Untersuchungen resultierenden Ergebnisse liefern einen wesentlichen Beitrag zum oben genannten Forschungsgebiet. Die in dieser Arbeit untersuchten Metall-Phthalocyanine (MePc) wurden so ausgewählt, dass eine möglichst große Vielfalt an geometrischen und elektronischen Eigenschaften abgedeckt wurde. Planare cobaltbasierte Phthalocyanin-Moleküle wurden in zwei Konfigurationen untersucht: einerseits das protonierte CoPc, das sich als organischer p-Halbleiter verhält, und andererseits das vollständig fluorinierte F16CoPc, das n-Halbleitereigenschaften besitzt. Bei beiden Systemen zeigte sich an der Position des Cobaltions eine Kopplung zwischen den Molkülorbitalen des Adsorbats und den Elektronenzuständen des Substrates. Das nichtplanare Zinn-Phthalocyanin ist von besonderem Interesse aufgrund seiner beiden möglichen Adsorptionskonformationen up und down, bei denen sich das Sn-Ion oberhalb beziehungsweise unterhalb des Phthalocyaninliganden befindet. Damit stellt dieses System einen möglichen Kandidaten für Anwendungen als molekularer Schalter oder als Speichereinheit dar. In der vorliegenden Studie werden lokalisierte Schaltvorgänge einzelner Moleküle zusammen mit der Möglichkeit einer kontrollierten molekularen Nanostrukturierung gezeigt. Lutetium (III) bisphthalocyanin wurde ausgewählt als Vertreter einer neuen Gruppe von MePc, die eine Sandwichstruktur ausbilden, bei der zwei π-konjugierte Phthalocyaninliganden über ein Seltenerd-Ion miteinander verbunden sind. Die Untersuchung dieses Systems liefert wichtige neue Erkenntnisse, wie zum Beispiel ein umfassendes Verständnis der Vorgänge bei der Selbstassemblierung innerhalb der ersten und zweiten organischen Monolage. Zudem wurde bei der Charakterisierung des Tunneltransports durch einzelne Moleküle mittels STS ein negativer differentieller Widerstand (NDR) gefunden, der von der Anzahl molekularer Lagen abhängt.

Fundação de Amparo a Pesquisa no Estado do Rio Grande do Sul / This research, predominantly qualitative and ethnographic in school life, has as its theme the curriculum and teacher training in teaching. This research is relevant for the importance and need for new curricular settings, based on the critical perspective and social context, have to trigger a process of profound transformation, shaking the linear style and curricular current thinking and for that a continuous and permanent training of teachers is required. The problem of investigation of this research is: What would be the possible progress made by the teachers of a public high school in the city of Restinga Sêca/RS when implementing curricular interventions from the perspective of thematic approach in regular and adult education groups of high school? Based on this question, the following objectives were outlined: to contribute through a formative and collective process with the teachers of Érico Veríssimo School for building curricular interventions guided by the thematic approach; to check with the teachers of this school if they adopt and how they adopt in their daily practice curricular interventions guided by the thematic approach; to analyze the opinions and perceptions of teachers at this school about the progress made when implementing curricular interventions guided by the thematic approach. The research was implemented in a public high school in the city of Restinga Sêca/RS during the year of 2012 and the sample consisted of teachers from the regular high school and adult education (EJA). The theoretical referential that guides the research is grounded in the assumptions of the educator Paulo Freire and in ideals of the educational implications of the movement Science-Technology-Society (STS). The instruments used for data collection were: questionnaire, participant observation (through notes and logbooks/field), document analysis and semistructured interview. Regarding the methodology of data analysis, it was used the Textual Discourse Analysis. The results were presented in the form of categories of advances achieved by teachers in implementing the thematic approach in the daily routine of that school entitled as: the importance of the training course, the theme worked from the reality, from the student(s)' context, the teachers' engagement in collective and interdisciplinary work, the change in concept of curriculum and the dialogue between teacher-student and student-student. By way of conclusion, it is important to emphasize that all these categories contribute to the change of the new style of curriculum thinking, since they are in agreement with the profound process of curricular reconfigurations buoyed in critical perspective and social context. It also highlights a new school space/time provided to the research by the new proposed restructuring of the polytechnic high school state system of Rio Grande do Sul, as well as their convergences and divergences in relation to the Reorientation Curriculum Movement in the city of São Paulo. / A presente pesquisa, de caráter predominantemente qualitativo e do tipo etnográfico no cotidiano escolar, tem como tema o currículo e a formação de professores no âmbito do ensino. Essa pesquisa torna-se relevante pela importância e necessidade que novas configurações curriculares, baseadas na perspectiva crítica e no contexto social, têm de deflagrar um processo de transformações profundas, abalando o estilo de pensamento curricular linear vigente e, para tal, é necessária uma formação contínua e permanente dos professores. O problema de investigação dessa pesquisa é: Quais seriam os possíveis avanços alcançados por professores de uma escola pública de ensino médio do município de Restinga Sêca/RS quando implementam intervenções curriculares na perspectiva da abordagem temática em turmas do ensino médio regular e EJA? A partir dessa questão, delinearam-se os objetivos da mesma: contribuir através de um processo formativo e coletivo com os professores da EEEM Érico Veríssimo para a construção de intervenções curriculares pautadas pela abordagem temática; verificar com os professores desta escola se adotam e como adotam, na sua prática cotidiana, intervenções curriculares pautadas pela abordagem temática; analisar as opiniões e percepções dos professores desta escola a respeito dos avanços alcançados quando se implementam intervenções curriculares pautadas pela abordagem temática. A pesquisa foi implementada em uma escola pública de ensino médio do município de Restinga Sêca/RS durante o ano de 2012 e a amostra foi constituída por professores do ensino médio regular e da EJA. O referencial teórico que baliza a pesquisa está alicerçado nos pressupostos do educador Paulo Freire e em ideais das repercussões educacionais do movimento Ciência-Tecnologia-Sociedade (CTS). Os instrumentos utilizados para a coleta dos dados foram: o questionário, a observação participante (através de registros e diários de bordo/campo), a análise documental e a entrevista semiestruturada. Quanto à metodologia de análise de dados, utilizou-se a Análise Textual Discursiva. Os resultados foram apresentados sob forma de categorias de avanços, alcançadas pelos professores na implementação da abordagem temática no cotidiano escolar da referida escola, intituladas de: a importância do curso de formação; o tema trabalhado a partir da realidade, do contexto do(s) aluno(s); o engajamento dos professores no trabalho coletivo e interdisciplinar; a mudança na concepção de currículo, e; o diálogo entre professor-aluno e aluno-aluno. À guisa de conclusões, é importante frisar que todas essas categorias contribuem para a mudança do novo estilo de pensamento curricular, uma vez que estão em comum acordo com o profundo processo de reconfigurações curriculares balizadas na perspectiva crítica e no contexto social. Também se destaca um novo espaço/tempo escolar proporcionado à pesquisa pela nova proposta de reestruturação do ensino médio politécnico da rede estadual gaúcha, bem como suas convergências e divergências em relação ao Movimento de Reorientação Curricular no município de São Paulo.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Curricular reorientation based on the Thematic Approach Freirean (TAF) articulated approach to Science, Technology and Society (STS) are possibilities, so that the linear curriculum, preparatory and fragmented schools is questioned and, for that to happen, it is essential to invest in the formation of educators. Thus, the research problem of this research is: What are the possibilities and challenges faced by educators Sciences (Biology, Physics and Chemistry), a public school in Santa Maria, to use the thematic approach in their classes, especially in structuring and implementing the theme "Arroio Cadena: Santa Postcard Maria? "?. In terms of research problem detailing, three objectives were assumed: Discuss how it came to Theme Generator to be developed from the study of Reality (SR); Develop a training collective and interdisciplinary process with educators, aimed at construction / reconstruction of the curriculum through the use of articulated TAF to focus STS; Investigate the possibilities and challenges encountered in the training process and in the development and implementation of educational design / learning. The survey was implemented in the State Preparatory High School Don Antonio Reis, in the city of Santa Maria / RS, during the year 2014. The theoretical reference used in the research is based on the TAF, following the steps of the Three Pedagogical Moments (3PM) as structuring the curriculum, assumptions of the educator Paulo Freire and ideals of focus STS and Latin American Thought in Science Technology and Society (LATSTS). The research was developed in different phases and in the first, It is made explicit the process for obtaining generator theme, from SR, and in the second, the formation process aiming at Thematic Approach (TA). With qualitative approach, the instruments used in the first phase were: document analysis of the school's pedagogical project; research in local newspapers; informal conversations with: Brazilian Institute of Geography and Statistics (BIGS), health post, prefecture, city planning institute and military brigade; interview with students, teachers, directive team and local community. In the second phase, the instruments used were: questionnaire on the first meeting of the formative process, daily researcher, recordings of the encounters of the formative process, teaching projects / elaborate learning, daily educators, interviews with educators and students. As a synthesis of research results initially is discussed as the generator theme emerged: Arroio Cadena: Postcard of Santa Maria? . Just after are discussed two emerging categories of analysis of the whole process using the Text Analysis Discourse (DTA) as methodology: Possibilities of an curricular reorientation the perspective of TA and Challenges of a curricular reorientation the perspective of TA In possibilities, are characteristics such as: interdisciplinary work and the extension of the collective work in school (school and local community), the contributions of the formative process in professional walk of educators, the shift in attitude and dialogue constructed between educator-students and awakening to a culture of participation. In the category of challenges, emerging problems related to the lack of time for interdisciplinary planning, the resistance of students in work developed and yet, the conceptual approach rooted in the concepts and practices. / Reorientações curriculares baseadas na Abordagem Temática Freireana (ATF) articulada ao enfoque Ciência- Tecnologia-Sociedade (CTS) são possibilidades, para que o currículo linear, propedêutico e fragmentado das escolas seja problematizado e, para que isso aconteça, é fundamental investir na formação dos educadores. Assim, o problema de investigação desta pesquisa é: Quais as possibilidades e desafios encontrados por educadores de Ciências (Biologia, Física e Química), de uma escola pública de Santa Maria, ao utilizarem a Abordagem Temática em suas aulas, especialmente na estruturação e implementação do tema Arroio Cadena: Cartão Postal de Santa Maria? . Em termos de detalhamento do problema de pesquisa, três objetivos foram assumidos: Discutir como se chegou ao Tema Gerador a ser desenvolvido, a partir do Estudo da Realidade (ER); Desenvolver um processo formativo coletivo e interdisciplinar com educadores, com vistas à construção/reconstrução do currículo, através da utilização da ATF articulada ao enfoque CTS; Investigar as possibilidades e desafios encontrados no processo formativo e na elaboração e implementação do projeto de ensino/aprendizagem. A pesquisa foi implementada na Escola Estadual de Ensino Médio Dom Antônio Reis, do município de Santa Maria/RS, durante o ano de 2014. O referencial teórico utilizado na pesquisa está fundamentado na ATF, que segue as etapas dos Três Momentos Pedagógicos (3MP) como estruturantes de currículos, pressupostos do educador Paulo Freire e nos ideais do enfoque CTS e do Pensamento Latino Americano em Ciência-Tecnologia-Sociedade (PLACTS). A pesquisa foi desenvolvida em diferentes fases, sendo que, na primeira, é explicitado o processo para obtenção do tema gerador, a partir do ER, e, na segunda, o processo formativo com vistas à Abordagem Temática (AT). Com cunho qualitativo, os instrumentos utilizados na primeira fase foram: análise documental do Projeto Pedagógico da escola; pesquisas em jornais locais; conversas informais com: Instituto Brasileiro de Geografia e Estatística (IBGE), posto de saúde, prefeitura, Instituto de planejamento da cidade e brigada militar; entrevista com educandos, educadores, equipe diretiva e comunidade local. Já na segunda fase, os instrumentos utilizados foram: questionário referente ao primeiro encontro do processo formativo, diários da pesquisadora, gravações dos encontros do processo formativo, projetos de Ensino/Aprendizagem elaborados, diários dos educadores, entrevista com os educadores e educandos. Como síntese dos resultados da investigação, inicialmente, é discutido como emergiu o tema gerador: Arroio Cadena: Cartão Postal de Santa Maria? . Logo após, são discutidas duas categorias emergentes da análise de todo o processo, utilizando a Análise Textual Discursiva (ATD) como metodologia: Possibilidades de uma reorientação curricular na perspectiva da AT e Desafios de uma reorientação curricular na perspectiva da AT. Nas possibilidades, encontram-se características como: o trabalho interdisciplinar e a ampliação do trabalho coletivo na escola (comunidade escolar e local), as contribuições do processo formativo na caminhada profissional dos educadores, a mudança de postura e o diálogo construído entre educador-educandos e o despertar para uma cultura de participação. Na categoria dos desafios, emergem problemas relacionados com a falta de tempo para o planejamento interdisciplinar, as resistências dos educandos no trabalho desenvolvido e, ainda, a abordagem conceitual enraizada nas concepções e práticas.
