In dieser Arbeit wird ein Konzept für das betriebliche Gesundheitsmanagement an einem Fachkrankenhaus für Neurologie und Psychiatrie erstellt. Hierbei werden zunächst allgemeine Grundlagen sowie die Entwicklung und Teilbereiche des betrieblichen Gesundheitsmanagements dargestellt. Darauf basierend wird anschließend am praktischen Beispiel eines Fachkrankenhauses für Neurologie und Psychiatrie mit Hilfe einer Mitarbeiterbefragung sowie einer Literaturrecherche ein organisatorisches und inhaltliches Konzept für das betriebliche Gesundheitsmanagement entworfen. Inhaltlich umfasst dieses die alters- und berufsgruppenspezifisch bedarfsorientierte Entwicklung von Maßnahmen und Angeboten an zwei Gesundheitstagen jährlich, sowie die dauerhafte Etablierung verschiedener Angebote zur Förderung der Gesundheit und Prävention von Erkrankungen der Mitarbeiter. Weiterhin werden die notwendigen organisatorischen Determinanten erarbeitet, die zur Einführung, Weiterentwicklung und Überprüfung der Wirksamkeit des BGM erforderlich sind. Im abschließenden Fazit erfolgen eine aktuelle Bewertung der Konzeption und ein Ausblick in die Zukunft.

Background: Mathematical modelling of biological processes often requires a large variety of different data sets for parameter estimation and validation. It is common practice that clinical data are not available in raw formats but are provided as graphical representations. Hence, in order to include these data into environments used for model simulations and statistical analyses, it is necessary to extract them from their presentations in the literature. For this purpose, we developed the freely available open source tool ycasd. After establishing a coordinate system by simple axes definitions, it supports convenient retrieval of data points from arbitrary figures. Results: After describing the general functionality and providing an overview of the programme interface, we demonstrate on an example how to use ycasd. A major advantage of ycasd is that it does not require a certain input file format to open and process figures. All options of ycasd are accessible through a single window which eases handling and speeds up data extraction. For subsequent processing of extracted data points, results can be formatted as a Matlab or an R matrix. We extensively compare the functionality and other features of ycasd with other publically available tools. Finally, we provide a short summary of our experiences with ycasd in the context of modelling. Conclusions: We conclude that our tool is suitable for convenient and accurate data retrievals from graphical representations such as papers. Comparison of tools reveals that ycasd is a good compromise between easy and quick capturing of scientific data from publications and complexity. Our tool is routinely applied in the context of biological modelling, where numerous time series data are required to develop models. The software can also be useful for other kinds of analyses for which published data are required but are not available in raw formats such as systematic reviews and meta-analyses.

This article describes the Xtrieval framework - a flexible platform for testing and evaluating different aspects of retrieval systems. The background for the design of the framework is to develop an extensible platform for the combination of text and content-based multimedia retrieval. We describe the general composition of the framework and its main functionality. An evaluation of the framework capabilities is given with two exemplary retrieval evaluation tasks.

Die manuelle Auswertung von Laue-Aufnahmen mittels der stereographischen Projektion im Wulffschen Netz stößt bei hochindizierten Orientierungen auf erhebliche Schwierigkeiten. Es wird eine einfache Kugelmethode beschrieben, die es gestattet, mit Hilfe des Greeninger Netzes jedes beliebig orientierte Lauebeugungsdiagramm in kurzer Zeit auszuwerten.

Die Ereignisanalyse 2013 ist nach den Auswertungen der Hochwasser von 2002 und 2010/11 der dritte ausführliche Bericht über ein Extremhochwasser in Sachsen. Ursache des Hochwassers im Juni 2013 in Sachsen waren die starken Niederschläge in Verbindung mit einer außerordentlich hohen Bodenfeuchte. Besonders betroffen waren neben dem Elbestrom das Einzugsgebiet der Mulde und der Weißen Elster. In der Zwickauer Mulde wurden dabei zum Teil Wasserstände erreicht, die die Werte des Augusthochwassers 2002 übertrafen. In weiten Teilen des Einzugsgebietes der Weißen Elster kam es zu einer extremen und so in den bisherigen hydrologischen Beobachtungen seit 1954 nicht mehr aufgetretenen Hochwassersituation. Der Bericht beinhaltet eine umfassende Analyse des Hochwasserereignisses. Es werden die meteorologischen und hydrologischen Prozesse sowie die aufgetretenen Schadensprozesse und die Schadensbilanz dargestellt. Markante Ereignisse werden in Fallbeispielen detailliert beschrieben. Ein wichtiger Bestandteil der Ereignisanalyse sind die Auswertungen des Ereignismanagements, der sozialen Netzwerke und des Hochwassernachrichtendienstes.

This short contribution shows the relevance of audiovisual sources for the history of 20th century music. It traces the role played by the violinist Fritz Kreisler (1875–1962) in shaping the widespread cliché of the “Viennese sound” via an examination of audiovisual sources. The sources stored in different online archives or social media portals play a key role, but the traceability of a given agent is not guaranteed. For this reason, controlled vocabularies and a digital tool which enable the addition of new metadata to already existing sources should be developed in the near future. This would enable researchers to trace agents, such as institutions and artists, and to connect them with places, repertoires and cultural topoi.

We discuss explanations in Description Logics (DLs), a family of logics used for knowledge representation. Initial work on explaining consequences for DLs had focused on justifications, which are minimal subsets of axioms that entail the consequence. More recently, it was proposed that proofs can provide more detailed information about why a consequence follows. Moreover, several measures have been proposed to estimate the comprehensibility of justifications and proofs, for example, their size or the complexity of logical expressions. In this paper, we analyze the connection between these measures, e.g. whether small justifications necessarily give rise to small proofs. We use a dataset of DL proofs that was constructed last year based on the ontologies of the OWL Reasoner Evaluation 2015. We find that, in general, less complex justifications indeed correspond to less complex proofs, and discuss some exceptions to this rule.
