Prüfungswesen an österreichischen medizinischen Universitäten – Überblick 2007

Seit 1995 war die „Grazer Konferenz - Qualität der Lehre" Diskussionsforum für Curriculum-Entwicklung der österreichischen medizinischen Universitäten. Ein Schwerpunkt der 11. Konferenz 2007, war Stand und Entwicklung des Prüfungswesens. Anhand von 10 Fragen erläuterten Vertreter der Universitäten das Vorgehen um gesetzlichen Auflagen sowie lokalen Notwendigkeiten Rechnung zu tragen. Obwohl die Überprüfung des Studienfortschritts sowie die Qualtitätskontrolle des Prüfungswesens unterschiedlich implementiert wurden, ist die Erfüllung internationaler Standards Ziel aller Universitäten. 15.11.2007 | Herbert Plass (Wien), L.

Methodological difficulties in the comparison of indicators of perinatal health across Europe

The main purpose of this article is to point out common pitfalls that can confuse comparative analyses of indicators of perinatal health and to discuss ways to overcome or minimize these difficulties. The challenge is to distinguish 'real' variations in the value of an indicator from variations due to differences in registration practices and definitions and from random variation. The first section presents the major properties that are desirable in indicators of perinatal health status and perinatal health care in Europe to be used for comparative purposes. The second section provides specific examples of the types of methodological difficulties encountered in European cross-country comparisons due to variations in the definition, measurement and construction of indicators. The conclusion discusses the PERISTAT project's responses to these difficulties and how these methodological constraints impact on the selection of an appropriate indicator set for Europe today. © 2003 Elsevier Ireland Ltd.

Evaluation of moisture sorption models and modified Mualem model for prediction of desorption isotherm for wood materials

Modeling of heat and moisture transport in wood based materials requires the knowledge of material properties such as sorption isotherms. Several water vapor sorption models available in literature are evaluated by fitting the sorption isotherm data of spruce (Picea abies) at 23°C. To take temperature effect into account, temperature dependent sorption models are adopted to fit the sorption data of Klinki pine at four temperatures. The results show that the Guggenheim-Anderson-de Boer (GAB) model, thermodynamic model and Dubinin-Astakhov (DA) function based on Polanyi moisture chemical potential have comparable excellent performances for fitting of sorption data. A modified Mualem model with a variable exponent, which is established based on similarity hypothesis, is used to generate desorption isotherm from measured adsorption isotherm. Only another intermediate point on desorption isotherm needs to be measured for the calibration of the exponent. If the sorption history of desorption isotherm is unknown, the measured desorption point will be preferred as the starting point for predicting desorption isotherm. Therefore, the experimental efforts to determine the main isotherm branches can be greatly reduced
