Method: We carried out this cross-sectional study of 50 stroke survivors (mean age=54.8 ± 8.8 years), at the physiotherapy Department of the University of Nigeria Teaching Hospital, Enugu. Data were collected using Becks Depression Inventory , it was analyzed using Z-scores, Chi-square test and univariate logistic regression. Results: PSD was more common in females (45.45%); middle-age(60%) adults(27-36/47-56 years respectively); living with spouse (45%); left cerebral lesions (40.74%). Self-employed and unemployed (66.67%), respectively. Age was significantly associated with depression (p=0.03), and was related to the risk ofOR3.7 (95% CI 1.1-12.0 ) Conclusion: Age could be a risk factor for PSD, which was more prevalent in the elderly than young/middle-age adults, female gender, left cerebral lesion, complications, cold case; those living with a spouse, self-employed and unemployed.

Diese Arbeit beschäftigt sich deshalb mit den Einsatzmöglichkeiten von AR in Öffentlichen Bibliotheken (ÖB). Betrachtet wird dabei die Realisierung von AR über eigenständig gestalteten Content mittels Anbietern im Internet und dazugehörigen Browser-Apps. Dies stellt eine kostengünstige und barrierefreie Alternative zur Programmierung von Apps dar. Dafür wird zunächst ein theoretischer Überblick gegeben, indem AR definiert wird und die technischen Grundlagen, wie Trackingverfahren und Interfaces, erläutert werden. Darauf folgen, zur Un-termauerung der Diskrepanz zwischen WB und ÖB, Beispiele für umgesetzte Projekte aus beiden Sparten. Anschließend wird auf die allgemeinen Einsatzgebiete und Potenziale von AR sowie die Aufgaben von ÖBs eingegangen. Die daraus abgeleiteten Einsatzmöglichkeiten von AR für Öffentliche Bibliotheken, Navigation und Orientierung, Bestandserweiterung, Veranstaltungen, Öffentlichkeitsarbeit/Marketing/Werbung sowie Informationskompetenz, werden erläutert. Zur Content-Gestaltung werden zunächst Grundvoraussetzungen genannt und die Funktionsweise der AR-Anbieter im Internet erklärt. Im Anschluss werden die Anbieter Blippar, HP Reveal, Layar, ROAR, Wikitude und Zappar, auf Grundlage eines zuvor erstellten Kriterienkatalogs, hinsichtlich ihres Funktionsumfangs verglichen. Im Ergebnis zeigt sich, dass sich die Anbieter zwar alle ähneln, bezüglich spezieller Funktionen und Kosten aber unterscheiden. Am besten schneidet dabei Zappar ab. Ergänzend werden danach die verschiedenen Arten von Content näher betrachtet. Zur Veranschaulichung der leichten Realisierbarkeit von AR werden zwei praktische Beispiele umgesetzt. Zum Abschluss werden Grenzen und Probleme, auch aus rechtlicher Perspektive, betrachtet. Diese schränken die Content-Gestaltung und die Einsatzmöglichkeiten nur wenig ein, womit die Content-Gestaltung von AR für den Einsatz in ÖBs sehr gut geeignet ist.

N2 - This article deals with the IT security of production plants from the operator‘s point of view. The focus is on the organizational aspects of IT security. The first step is to identify the problems that arise when an organization focuses essentially on technical aspects of IT security. Conclusions are drawn about the necessary organizational measures. An examination of regulations and standards that deal with the organizational aspects of IT security in production provides the basis for formulating an action plan. The 10-point plan for the implementation of IT security in production concludes the contribution.

It investigates the vacancies and requirements of these positions in the German-speaking countries by analyzing one hundred and fifty published job advertisements of OpenBiblioJobs between 2012-2016. In addition, the distribution of positions, institutional bearers, different job titles as well as time limits, scope of work and remuneration of the positions are evaluated. The analysis of the remuneration in the public sector in Germany also provides information on demands for a bachelor's or master's degree. The average annual increase in job vacancies between 2012 and 2016 is 14.19%, confirming the need and necessity of these professional library profiles. The higher remuneration of the positions in data management, in comparison to the systems librarian, proves the prerequisite of the master's degree and thus indicates a desideratum due to missing or few master's degree courses. Accordingly, the range of bachelor's degree courses (or IT-oriented major areas of study with optional compulsory modules in existing bachelor's degree courses) for systems and IT librarians must be further expanded. An alternative could also be modular education programs for librarians and information scientists with professional experience, as it is already the case for music librarians.

At the same time, companies in the mass tourism market have increasingly marketed themselves with a “green” image, although this market is not sustainable. In order to successfully market sustainability, targeted marketing tactics are needed. The aim of this research is to establish appropriate marketing tactics for sustainable tourism in the niche market and in the mass market. The purpose is to uncover current marketing tactics for both the mass tourism market and the sustainable tourism niche market. It also intends to explore how consumers who are more interested in sustainability differ from consumers with less interest in sustainability in terms of their perception of sustainability in tourism. Furthermore, this research paper will assess the trustworthiness of sustainable travel offers and the trustworthiness of quality seals in sustainable tourism. For this purpose, an online survey was conducted, which was addressed at German-speaking consumers. The survey showed, that consumers with more general interest in sustainability also consider sustainability to be more relevant in tourism. Offers for sustainable travel and quality seals were perceived as not very trustworthy. Moreover, no link could be found between the interest in sustainability and the perception of trustworthiness. On the basis of the above, it is advisable to directly advertise sustainability in the niche market and to mention sustainability in the mass market only as an accompaniment or not at all. Further research could be undertaken to identify which factors influence the trustworthiness of offers, and trustworthiness of quality seals in sustainable tourism.

T1 - The challenge of extra-intra craniometry: a computer-assisted three-dimensional approach on the equine skull JF - Folia Morphologica N2 - Background: The topographical correlations between certain extracranial and intracranial osseous points of interest (POIs), and their age-related changes, are indispensable to know for a diagnostical or surgical access to intracranial structures; however, they are difficult to assess with conventional devices. Materials and methods: In this pilot study, the 3-dimensional coordinates of extra-/intracranial POIs were determined, thus avoiding perspective distortions that used to be intrinsic problems in 2-dimensional morphometry. The data sets were then analysed by creating virtual triangles. The sizes, shapes, and positions of these triangles described the extent and the directions of the age-related shifts of the POIs. A selection of extracranial and intracranial POIs were marked on half skulls of four warmblood horses in two age groups (young: 6 weeks, n = 2; old: 14 and 17 years, n = 2). The x-, y-, and z-coordinates of these POIs were determined with a measurement arm (FaroArm Fusion, FARO Europe®). Direct distances between the POIs as well as their indirect distances on the x-, y-, and z-axis, and angles were calculated. Results: The analysed virtual triangles revealed that some parts of the skull grew in size, but did not change in shape/relative proportions (proportional type of growth, as displayed by POI A and POI B at the Arcus zygomaticus). The same POIs (A and B) remained in a very stable relationship to their closest intracranial POI at the Basis cranii on the longitudinal axis, however, shifted markedly in the dorso-lateral direction. In contrast, a disproportional growth of other parts of the cranium was, for example, related to POI C at the Crista nuchae, which shifted strongly in the caudal direction with age. A topographically stable reference point (so-called anchor point) at the Basis cranii was difficult to determine. Conclusions: Two candidates (one at the Synchondrosis intersphenoidalis, another one at the Synchondrosis sphenooccipitalis) were relatively stable in their positions. However, the epicentre of (neuro-)cranial growth could only be pinpointed to an area between them.

Although the imaging costs are steadily falling, capturing the accompanying label information is still predominantly done manually and develops into the principal cost factor. In order to streamline the process of capturing herbarium specimen metadata, we specified a formal extensible workflow integrating a wide range of automated specimen image analysis services. We implemented the workflow on the basis of OpenRefine together with a plugin for handling service calls and responses. The evolving system presently covers the generation of optical character recognition (OCR) from specimen images, the identification of regions of interest in images and the extraction of meaningful information items from OCR. These implementations were developed as part of the Deutsche Forschungsgemeinschaft funded a standardised and optimised process for data acquisition from digital images of herbarium specimens (StanDAP-Herb) Project.

T1 - Association between teat skin colonization and intramammary infection with Staphylococcus aureus and Streptococcus agalactiae in herds with automatic milking systems JF - Journal of Dairy Science N2 - The objective of this study was to investigate the association between teat skin colonization and intramammary infection (IMI) with Staphylococcus aureus or Streptococcus agalactiae at the quarter level in herds with automatic milking systems. Milk and teat skin samples from 1,142 quarters were collected from 300 cows with somatic cell count >200,000 cells/mL from 8 herds positive for Strep. agalactiae. All milk and teat skin samples were cultured on calf blood agar and selective media. A subset of samples from 287 quarters was further analyzed using a PCR assay (Mastit4 PCR; DNA Diagnostic A/S, Risskov, Denmark). Bacterial culture detected Staph. aureus in 93 (8.1%) of the milk samples and 75 (6.6%) of the teat skin samples. Of these, 15 (1.3%) quarters were positive in both the teat skin and milk samples. Streptococcus agalactiae was cultured in 84 (7.4%) of the milk samples and 4 (0.35%) of the teat skin samples. Of these, 3 (0.26%) quarters were positive in both the teat skin and milk samples. The PCR detected Staph. aureus in 29 (10%) of the milk samples and 45 (16%) of the teat skin samples. Of these, 2 (0.7%) quarters were positive in both the teat skin and milk samples. Streptococcus agalactiae was detected in 40 (14%) of the milk samples and 51 (18%) of the teat skin samples. Of these, 16 (5.6%) quarters were positive in both the teat skin and milk samples. Logistic regression was used to investigate the association between teat skin colonization and IMI at the quarter level. Based on bacterial culture results, teat skin colonization with Staph. aureus resulted in 7.8 (95% confidence interval: 2.9; 20.6) times higher odds of Staph. aureus IMI, whereas herd was observed as a major confounder. However, results from the PCR analyses did not support this association. Streptococcus agalactiae was isolated from the teat skin with both PCR and bacterial culture, but the number of positive teat skin samples detected by culture was too low to proceed with further analysis. Based on the PCR results, Strep. agalactiae on teat skin resulted in 3.8 (1.4; 10.1) times higher odds of Strep. agalactiae IMI. Our results suggest that Staph. aureus and Strep. agalactiae on teat skin may be a risk factor for IMI with the same pathogens. Focus on proper teat skin hygiene is therefore recommended also in AMS.

Aus Sicht eines Betreibers von Autobewerter-Systemen erfordert letzteres meist die Ausführung von fremdem Programmcode in der eigenen Server-Umgebung. Hierbei ist Vorsicht geboten, da fehlerhafter oder angriffslustiger Programmcode verbotene Aktionen ausführen könnte. An der Hochschule Hannover können Studierende Lösungen zu Programmieraufgaben verschiedener Programmiersprachen über das Lernmanagementsystem "moodle" einreichen. Die angeschlossene Middleware Grappa nimmt Lösungen anschließend entgegen und leitet diese an einen Autobewerter der zugehörigen Programmiersprache weiter. Diese Arbeit befasst sich damit, Sicherheitsrisiken bei der Ausführung von fremdem Programmcode durch Autobewerter zu identifizieren und zu vermeiden. Hierzu gilt es, mögliche Angriffe herauszustellen und aktuelle, angemessene Technologien zu finden, um diese zu verhindern. Anschließend findet mit einer Technologie die Entwicklung einer abgesicherten Ausführungsumgebung für beliebige an die Middleware Grappa angebundene Autobewerter statt. Die exemplarische Einbettung der beiden Autobewerter Graja und Praktomat in die entwickelte Ausführungsumgebung soll unter Beweis stellen, dass es sich um eine generische Lösung mit wenig Overhead handelt.
