Konzeption, Implementierung und Anwendung eines automatisierten aerothermodynamischen Vorentwurfsprozesses für Axialturbinen

In dieser Arbeit wird ein Prozess für den frühen aerothermodynamischen Entwurf von Axialturbinen konzipiert und durch Kopplung einzelner Computerprogramme im DLR Göttingen realisiert. Speziell für die Erstauslegung von Geometrien und die Vorhersage von globalen Leistungsdaten beliebiger Axialturbinen wurde ein neues Programm erzeugt. Dessen effiziente Anwendung wird mit einer zu diesem Zweck konzipierten grafischen Entwurfsumgebung ausgeführt. Kennzeichnend für den Vorentwurfsprozess in dieser Arbeit ist die Anwendung von ein- und zweidimensionaler Strömungssimulation sowie der hohe Grad an Verknüpfung der verwendeten Programme sowohl auf prozesstechnischer wie auch auf datentechnischer Ebene. Dabei soll dem sehr frühen Entwurf eine deutlich stärkere Rolle zukommen als bisher üblich und im Gegenzug die Entwurfszeit mit höher auflösenden Vorentwurfsprogrammen reduziert werden. Die Anwendung der einzelnen Programme im Rahmen von Subprozessen wird anhand von exemplarischen Turbinenkonfigurationen in der Arbeit ebenso dargestellt, wie die Validierung des gesamten Entwurfsprozesses anhand der Auslegung einer folgend realisierten und erfolgreich operierenden Axialturbine eines Triebwerkssimulators für Flugzeug-Windkanalmodelle (TPS). Neben der Erleichterung von manueller Entwurfstätigkeit durch grafische Benutzerinteraktion kommt in einzelnen Subprozessen eine automatisierte Mehrziel-Optimierung zum Einsatz.

O presente trabalho é de natureza quantitativa e qualitativa, tipo estudo de caso e o campo de aplicação foi Escola Municipal Amabílio Vieira dos Santos. Quanto à revisão teórica buscou-se conceituar o currículo e suas nuances para tomá-lo adequado à realidade. A pesquisa envolveu estudos sobre diferenças sociais do Bairro Santa Cruz. Tratou-se de uma pesquisa descritiva, quanto aos fins e meios, bem como, uma pesquisa-ação participativa, pois envolveu procedimentos que integram a comunidade escolar e demais parceiros, sendo um projeto de ação social e cultural. Na finalização do trabalho elaboraram-se as considerações e limitações quanto ao desenvolvimento do Projeto Oficina Escola. ABSTRACT; This study it analyses the importance of to implement School Workshop Project to provide the students the opportunity acquiring competences and abilities, performing an innovated management of learning observing the school flexibility inserting the practice of Art in a full time system, as an alternative curriculum. The present work composition is a quantity and qualitative one, kind case study e the field of its application was the Municipal School Amabílio Vieira Dos Santos. White the theory review, it searches to give the concept of the curriculum and its particularities to become it appropriated to the reality. The research involved studies about the social differences at the District Santa Cruz. It was a descriptive research, white the finals and insides, as well a participative research, because it involved procedures that integrated the school community partners, being a social and cultural project. The finalization of this work elaborates the considerations and limitations as the development of the School Work shop Project.

Contextual factors related to chronic condition in portuguese adolescents: Highlights from the HBSC/WHO study

Adolescence’s changes may become more pronounced when living with a chronic condition (CC). This study aims to examined the differences in satisfaction with family life, perception of school competence and “pressure with homework” of Portuguese adolescents’ 1) living with CC; 2) how living with CC affects school participation; taking into account age, gender and family socioeconomic status (SES). Five thousand fifty Portuguese adolescents (mean age 14 ± 1.85) of the Health Behaviour in School-aged Children (HBSC/WHO) were included. Results showed increased vulnerability in adolescents living with CC, presenting a lower satisfaction with family life and poor school outcomes. Younger boys, having a higher SES and not having CC are significantly associated with satisfaction with family life. Older girls, having a lower SES and living with CC were associated with more stress related to school work. Future interventions should include these features combined with ‘listening’ to adolescents and their needs, allowing their participation in the promotion of personal health.

School students and part-time work: Workplace problems and challenges.

This paper uses data from a large national project on student-working to examine problems and challenges for school students working in part-time jobs. While literature has identified some potential problems and challenges, and some potential difficulties can be extrapolated from the nature of a young teenage workforce and the nature of the workplaces, these were largely absent in the two companies researched because the companies already had policies in place that addressed the potential problems. Some suggestions are made about how problems and challenges could be avoided in a wider range of adolescent workplaces.

Part-time work of high school students and impact on educational outcomes

While increasing numbers of young high school students engage in part-time work, there is no consensus about its impact on educational outcomes. Indeed this field has had a dearth of research. The present paper presents a review of recent research, primarily from Australia and the US, although it is acknowledged that there are considerable contextual differences. Suggestions for school counsellors to harness the students’ experiences to assist in educational and career decision-making are presented.

A principal at work : a story of leadership for building sustainable capacity of a school

This study explores through a lifestream narrative how the life experiences of a female primary school principal are organised as practical knowledge, and are used to inform action that is directed towards creating a sustainable school culture. An alternative model of school leadership is presented which describes the thinking and activity of a leader as a process. The process demonstrates how a leader's practical knowledge is dynamic, broadly based in experiential life, and open to change. As such, it is described as a model of sustainable leadership-in-process. The research questions at the heart of this study are: How does a leader construct and organize knowledge in the enactment of the principal ship to deal with the dilemmas and opportunities that arise everyday in school life? And: What does this particular way of organising knowledge look like in the effort to build a sustainable school community? The sustainable leadership-in-process thesis encapsulates new ways of leading primary schools through the principalship. These new ways are described as developing and maintaining the following dimensions of leadership: quality relationships, a collective (shared vision), collaboration and partnerships, and high achieving learning environments. Such dimensions are enacted by the principal through the activities of conversations, performance development, research and data-driven action, promoting innovation, and anticipating and predicting the future. Sustainable leadership-in-process is shared, dynamic, visible and transparent and is conducted through the processes of positioning, defining, organising, experimenting and evaluating in a continuous and iterative way. A rich understanding of the specificity of the life of a female primary school principal was achieved using story telling, story listening and story creation in a collaborative relationship between the researcher and the researched participant. as a means of educational theorising. Analysis and interpretation were undertaken as a recursive process in which the immediate interpretations were shared with the researched participant. The view of theorising adopted in this research is that of theory as hermeneutic; that is, theory is generated out of the stories of experiential life, rather than discovered in the stories.
