However, these EAFs were not conceived for today’s rapidly digitalized enterprises and the associated IT complexity. A digitally-centric EAF is needed, freed from the past restrictive EAF paradigms and embracing the new potential in a data-centric world. This paper proposes an alternative EAF that is digital, holistic, and digitally sustainable - the Digital Diamond Framework. D2F is designed for responsive and agile enterprises, for aligning business plans and initiatives with the actual enterprise state, and addressing the needs of EA for digitized structure, order, modeling, and documentation. The feasibility of D2F is demonstrated with a prototype implementation of an EA tool that applies its principles, showing how the framework can be practically realized, while a case study based on ArchiSurance example and an initial performance and scalability characterization provide additional insights as to its viability.

Alternative database types such as NoSQL grow in popularity and allow data to be stored and accessed more simply or in new ways. Thus, software developers, not just database specialists, are more likely to encounter and need to deal with databases. Virtual Reality (VR) technology has grown in popularity, yet its integration in the software development tool chain has been limited. One potential application area for VR technology that has not been sufficiently explored is database-model visualization. This paper describes Virtual Reality Immersion in Data Models (VRiDaM), a generic database-model approach for visualizing, navigating, and conveying database-model information interactively. It describes and explores both native VR and WebVR solution concepts, with prototypes showing the viability of the approach.

Economic theory suggests that, nowadays, traditional location factors such as access to resources and a performant infrastructure are less important than in the industrial age. Recently, factors like a city’s potential to generate and retain human and creative capital have emerged. Accordingly, the economic and social role of cities has shifted – from a place where workers lived and manufactured goods towards a deeply interwoven ecosystem of knowledge-intense value creation. The question at the root of the present study is how Heidenheim’s rich industrial cultural heritage can be used as a future-pointing source of power for rebranding the town. This rebranding concept has to be developed according to the town’s role in past, present and future, thus creating actual economic and societal value. Industrial culture bears branding potential and is closely related to various aspects of modern life and work. The study examines possibilities to create awareness for these relations connecting past, present and future. Their relevance shall be emphasized in order to establish both points of orientation and authenticity of place in times when macroeconomic and societal trends are difficult to predict. Ideally, residents shall be given a sort of local identification to hold on to, and potential investors and entrepreneurs shall be encouraged to sustainably experience the innovation-based DNA of Heidenheim. Therefore, the study searches for a value proposition that takes into account the points mentioned above on terms of an innovative theoretic framework. As a result of this thesis, precise suggestions for the implementation of a new branding strategy based on the conceptual guidelines developed in this study will be proposed to the municipality of Heidenheim and, in addition, an interface using principles of virtual and augmented reality will be introduced.

Changed lifestyle and behavior are the main causes. For the pathogenesis of myopia, the amount of time spent outdoor and near activities play an important role. Various options for the treatment of myopia have been described as effective in the literature. Normal single vision glasses and contact lenses can only provide clear vision, but do not reduce myopia progression. Orthokeratology shows a slowing of axial growth, but has an increased risk of infectious keratitis. Low-dose atropine (0.01%) is currently the best pharmacological option. It proved safe, effective and showed the least rebound effect with negligible side effects. Other options for the treatment of myopia include special glasses, behavioral changes and prolonged outdoor exposure (to prevent the onset of myopia), as well as other methods. An increasingly important myopia management option is multifocal contact lenses, that provide a peripheral treatment zone producing myopic defocus. Such myopia control lenses are available as customized or as daily or monthly lenses. Children benefit from wearing contact lenses more than just having refractive error correction and myopia control, they have a better self-esteem and improved quality of life. The numerous findings on the safety and efficacy of soft multifocal distance center contact lenses in children to reduce the progression of myopia suggest that this modality should be considered as a main treatment option. Less, but similar to orthokeratology, when wearing soft lenses there is a risk of developing potentially serious complications such as microbial keratitis. The introduction of child-appropriate risk minimization strategies, and patient and parent education with regular monitoring is essential and leads to successful contact lens wear. This literature review summarized the actual knowledge about myopia management, prevalence, etiology and the visual and healthy consequences of myopia. The three currently most important strategies for slowing the progression of myopia are soft multifocal distance center contact lenses, Orthokeratology and low-dose atropine ophthalmic drops. N2 - Die zunehmende Verbreitung von Kurzsichtigkeit in der gesamten industrialisierten Welt in den letzten Jahrzehnten hat Kosten und Probleme für die Augengesundheit verursacht. Veränderungen im Lebensstil und Verhalten sind die Hauptursachen. Für die Pathogenese der Myopie spielt die Zeit, die im Freien und mit Aktivitäten in der Nähe verbracht wird, eine wichtige Rolle. Verschiedene Möglichkeiten zur Behandlung von Myopie wurden in der Literatur als wirksam beschrieben. Normale Einstärkenbrillen und Kontaktlinsen bieten nur eine klare Sicht, verringern jedoch nicht das Fortschreiten der Myopie. Die Orthokeratologie zeigt eine Verlangsamung des axialen Wachstums, hat jedoch ein erhöhtes Risiko für eine infektiöse Keratitis. Niedrig dosiertes Atropin (0,01%) ist derzeit die beste pharmakologische Option. Diese erwies sich als sicher, wirksam und zeigte den geringsten Reboundeffekt mit vernachlässigbaren Nebenwirkungen. Andere Optionen für die Behandlung von Myopie umfassen spezielle Brillen, Verhaltensänderungen und längerer Aufenthalt im Freien (um das Einsetzen von Myopie zu verhindern) sowie andere Methoden. Eine zunehmend wichtige Option für das Myopiemanagement sind multifokale Kontaktlinsen, die eine periphere Behandlungszone bieten, die einen peripheren myopischen Defokus hervorruft. Solche Myopiekontrolllinsen sind als kundenspezifische oder als Tages- oder Monatslinsen erhältlich. Kinder profitieren vom Tragen von Kontaktlinsen nicht nur von der Korrektur von Brechungsfehlern und der Kontrolle Ihrer Kurzsichtigkeit, sondern auch von einem besseren Selbstwertgefühl und einer verbesserten Lebensqualität. Die zahlreichen Ergebnisse zur Sicherheit und Wirksamkeit von weichen, multifokalen Kontaktlinsen mit Fernsicht im Zentrum bei Kindern zur Verringerung des Fortschreitens der Myopie legen nahe, dass diese Modalität als Hauptbehandlungsoption in Betracht gezogen werden sollte. Weniger, aber ähnlich wie in der Orthokeratologie, besteht beim Tragen weicher Linsen das Risiko, dass potenziell schwerwiegende Komplikationen wie mikrobielle Keratitis auftreten. Die Einführung kindgerechter Risikominimierungsstrategien sowie eine regelmäßige Überwachung und Patienten- und Elternaufklärung sind unerlässlich, und führen zu einem erfolgreichen Tragen von Kontaktlinsen. Diese Literaturübersicht fasst das aktuelle Wissen über Myopiemanagement, Prävalenz, Ätiologie und die visuellen und gesundheitlichen Konsequenzen von Myopie zusammen. Die drei derzeit wichtigsten Strategien zur Verlangsamung des Fortschreitens der Myopie sind weiche, multifokale Kontaktlinsen mit Fernsicht im Zentrum, Orthokeratologie und niedrig dosierte Atropin-Augentropfen.
