Die Verwendung der Ultraschalltechnik als bildgebendes Verfahren geh?rt in den unterschiedlichsten Bereichen der Medizin
zur klinischen Routine. In den letzten Jahren sind sowohl bei der Weiterentwicklung der Echoscanner selbst als auch auf der
Softwareseite im Bereich der computer-gestützten Auswertung von Ultraschalldaten enorme Fortschritte erzielt worden. Die Ergebnisse
der T?tigkeiten im Sonderforschungsbereich 414 “Rechner- und sensorgestützte Chirurgie” sind bedeutsame Beispiele der Fortschritte
in der klinischen Anwendung in unterschiedlichen medizinischen Fachrichtungen. Wir zeigen ein Beispiel aus der 3D-Echographie
(Diagnose von Knochentumoren und ihren Auswirkungen auf das umgebende Weichgewebe) und zwei Beispiele aus der Echokardiographie
(Vermessung von Herzklappenringen und Diagnose von Herzklappeninsuffizienzen durch Volumetrie und Visualisierung). Die echokardiographischen
Anwendungen unterscheiden sich dabei hinsichtlich der verwendeten Ultraschallinformation. W?hrend für die Vermessung von Herzklappenringen
die morphologische Information aus den Backscatterdaten gewonnen wird, wird bei der Bestimmung von Flu?volumen auf die Dopplerdaten
zurückgegriffen. 相似文献
Various authors have stressed the need for an adequate archiving and preservation policy of audiovisual material, given its cultural, historical, juridical, social and economic value. In view of the sustainable preservation of audiovisual material, the opening up of the archive is seen as a real challenge. Various aspects, such as requirements concerning formats, metadata standards and legal implications, need to be taken into account. Furthermore, different types of users should be able to consult the archive in a user-friendly way, a factor which should not be neglected. This article studies and discusses the current situation in Flanders regarding the digitisation and disclosure of the Flemish audiovisual cultural heritage, comprising the audiovisual material in the archives of different Flemish institutions, including broadcasters, (post-) production companies, government institutions and cultural organizations. Based on 45 qualitative interviews, a SWOT analysis is created to assess the strengths, weaknesses, opportunities and threats concerning the digitisation and disclosure of the audiovisual archive. Moreover, this environmental analysis includes some recommendations concerning the future preservation of this audiovisual cultural heritage. 相似文献
Research and design activities are important focus points in international policies for secondary Science, Technology, Engineering and Mathematics (STEM) education. It is up to school teachers to implement and supervise these activities in the STEM classroom. However, not much is known about the attitudes teachers hold towards supervising research projects or design projects. In this study, a questionnaire to measure teacher attitudes towards supervising research activities and design activities in secondary school was completed by 130 Dutch teachers who taught the relatively new Dutch STEM subjects O&O (research and design) and NLT (nature, life, and technology). These integrated STEM subjects are project and context based and are taught in a limited number of schools. Important differences between these integrated STEM subjects are their student and teacher populations: NLT is taught in grades 10–12 by teachers with a qualification in a science subject, while O&O is taught in grades 7–12 and can be given by any teacher in secondary school. The results showed that on average, both O&O and NLT teachers had high self-efficacy scores on supervising research and design projects even when they had received no special education in doing so. Furthermore, the teachers in general viewed supervising research projects as a more relevant activity than supervising design. Since research and design activities are becoming more important in (inter)national curriculum standards, STEM teacher education and subsequent professional development should not only familiarize teachers with supervising research projects, but with design projects as well.
This article aims to analyse the disciplinary procedures brought against public schoolteachers in Galicia from 1859 until 1910. The article starts with the presentation of the legal basis for the government inquiries and the administrative framework in which they were implemented. Following is an examination of the evolution of the inquiries, the origin of the complaints, the charges filed against the teachers and the sanctions proposed. Lastly some examples are provided of the most widespread offences, consisting of abandonment of teaching as well as other charges of moral misconduct such as cohabitation and sexual abuse of the children. 相似文献
