Keywords
The digitalization of schools not only affects students but also teachers, parents and school authorities. This raises various questions. Central question is the extent to which digitization is to be implemented. However, it is also important to understand what problems occur and what priorities need to be set for digitalization. A continuum between reality and virtuality, as Milgram described it, could be a helpful approach.
But it is not enough to just look at one perspective. Opinions and wishes of students, teachers and parents must be taken into account. In addition, decision-makers who have a direct influence on organizational and political decisions must also be included. The interests of these groups are embedded in strategies and laws that represent the political basis of digitalization.
The results of surveys, interviews and research show that the idea of a continuum between pure presence learning and pure e-learning is a good approach, but does not cover all aspects of school digitalization. The real problem is the different priorities of those involved and not the levels of digitalization. The purpose of digitalization often fades into the background. Content and pedagogical effectiveness and efficiency must be taken into account alongside technical best practice. The two-dimensional continuum must therefore be expanded into a “cube of school digitalization” whose edges describe the parameters of digitalization.
Next Generation Internet
(2024)
Die Entwicklung des Internets, insbesondere des WWW, stößt aktuell an ihre Grenzen – sowohl technisch als auch sozio-kulturell und ökonomisch. Als Lösung wird ein neues Internet versprochen, das die Grenzen der realen und der virtuellen Welt überwinden und Realität und Digitalität verschmelzen soll – das Metaversum. Technische, semantische und organisatorische Details greifen hierzu eng ineinander. Was aber bedeutet dies bei genauerer Betrachtung? Welche technisch-technologischen Herausforderungen müssen bewältigt werden, um ein solches Verschmelzen zu erreichen? Welche ökonomischen Möglichkeiten eröffnen sich– und welche verbieten sich möglicherweise? Wie kann erreicht werden, dass ein offenes und für jeden benutzbares Metaversum entsteht? Und wie kann vermieden werden, dass auch in diesem neuen Metaversum wenige große Anbieter ihre proprietären Ideen durchsetzen? Für diese Fragen soll dieses Buch Antworten aufzeigen.
In 2021, a prominent Austria dairy producer suffered from an IT attack and was completely paralysed. Without clearly defined mitigation measures in place, major disruptions were caused alongside the whole supply chain, including logistics service providers, governmental food safety bodies, as well as retailers (i.e., supermarkets and convenience stores). In this paper, we ask the question how digitisation and digital transformation impact IT security, especially when considering the complex company ecosystems of food production and food supply chains in Austria. The problem statement stems from a gap in knowledge of key differences in approaches towards IT security, resilience, risk management and especially business interfaces between food suppliers, supermarkets, distributors, logistics and other service providers. In order to answer related research questions, firstly, the authors conduct literature research, and highlight common guidelines and standardisation as well as look at state-based recommendations for critical infrastructure. In a second step, the paper describes a quantitative and qualitative survey with Austrian food companies (producers and retailers) which is described in detail in the paper. A description of recommended measures for the industry, further steps, as well as an outlook conclude the paper.
ROS 2 in Embedded Systemen
(2022)
Das Robot Operating System in seiner zweiten Version (ROS 2) findet zunehmend Verwendung und das nicht nur in Robotern. Dieser Beitrag gibt einen Überblick über den Aufbau und die Funktion von ROS 2. Die wesentlichen Elemente werden vorgestellt, das Publish-Subscribe-Konzept, das der Kommunikation zugrunde liegt, wird erläutert. Die Anforderungen von ROS 2 an Hardware und Betriebssystem werden beleuchtet und es werden Betrachtungen zu dessen Echtzeitverhalten gemacht.
A trend from centralized to decentralized production is emerging in the manufacturing domain leading to new and innovative approaches for long-established production methods. A technology supporting this trend is Cloud Manufacturing, which adapts technologies and concepts known from cloud computing to the manufacturing domain. A core aspect of Cloud Manufacturing is representing knowledge about manufacturing, e.g., machine capabilities, in a suitable form. This knowledge representation should be flexible and adaptable so that it fits across various manufacturing domains, but, at the same time, should also be specific and exhaustive. We identify three core capabilities that such a platform has to support, i.e., the product, the process and the production.We propose representing this knowledge in semantically specified knowledge graphs, essentially creating three through features interconnected ontologies each representing a facet of manufacturing. Finally, we present an exemplary implementation of a Cloud Manufacturing platform using this representation and its advantages.
