The Elephant in the Room - Educating Practitioners on Software Development for Sustainability
(2021)
In dem vorliegenden Beitrag wird der aktuelle Trend, Payas-you-live-Systeme (PAYL) in Verbindung mit Krankenversicherungen anzubieten, analysiert. PAYL-Systeme bedeutet konkret die kontinuierliche Erfassung von Gesundheitsdaten mithilfe technischer Geräte und Übermittlung dieser Daten an Versicherungen sowie die Auszahlung von Boni für erreichte Fitnessziele. Zunächst wird eine Definition von PAYL-Systemen dargelegt, dann werden die technischen Rahmenbedingungen erläutert, schließlich werden die Auswirkungen dieser soziotechnischen Systeme näher beleuchtet. Dies geschieht auf Grundlage unserer empirischen Untersuchung. Die drei identifizierten Hauptkonflikte betreffen die Genese von PAYL, seine Auswirkungen auf den Wert der Datensouveränität besonders für Versicherte und die Schwierigkeit, für den Anspruch auf Prävention und Kostenersparnis durch PAYL Evidenz zu erzeugen. Diese Konflikte werden diskutiert, um sowohl die direkten wie auch indirekten Auswirkungen der Digitalisierung und der Ökonomisierung des Sozialen durch PAYL zu beleuchten.
Sustainability is a major concern for our society today. Software acts as a catalyst to support different business activities which have an impact on sustainability. Research from software engineering and other academic disciplines have proposed various software sustainability guidelines, tools, and methods to support software sustainability design in industry. However, there are still challenges on how to design and engineer sustainability into software products by software development practitioners in industry using those proposed sustainability guidelines and tools. The goal of this research is to seek understanding on what software sustainability means for software development practitioners and identify how to properly support engineering of sustainability into software design and development through academic research. Data were gathered and analyzed using grounded theory from workshop with different software development practitioners to seek their understanding on what sustainability means in their software systems. The results show economic and technical sustainability dimensions are the most important to software development practitioners for software sustainability. While the social sustainability dimension was not considered for software sustainability. The findings from this study indicates contrast in academia where all sustainability dimensions are treated as an important element to achieve software sustainability. Therefore, there is need for better collaboration between industry and academia to improve understanding of software sustainability and support effective sustainability engineering in software systems.
Context: It is impossible to imagine our everyday and professional lives without software. Consequently, software products, especially socio-technical systems, have more or less obvious impacts on almost all areas of our society. For this purpose, a group of scientists worldwide has developed the Sustainability Awareness Framework (SusAF) which examines the impacts on five interrelated dimensions: social, individual, environmental, economic, and technical. According to this framework, we should design software to maintain or improve the Sustainability Impacts. Designing for sustainability is a major challenge that can profoundly change the field of activity – particular for Software Engineers. Objectives: The aim of the thesis work is to analyze the current role of Software Engineers and relate it to Sustainability Impacts of Software Products in order to contribute to this paradigm shift. This should provide a basis for follow-up works. The question in which direction exactly the Software Engineer should develop and how exactly this path can be followed is still owed by the scientific community. Perhaps universities will have to adapt the curriculum in the training of Software Engineers, politics could possibly initiate support programs in the field of sustainability for software companies, or maybe software sustainability certifications could emerge. In any case, Software Engineers must adapt to the times and acquire the necessary knowledge, the skills and the competencies. Results: The results of the dissertation are a better understanding of the needed paradigm shift of Software Engineers and comeplement the SusAF that to better support sustainability design. The extended SusAF is intended for both training and corporate use.
Digitale Pflegedokumentation, Robotik oder automatisierte Matratzensysteme zur Dekubitusprophylaxe: Pflegetechnologien stellen ein zunehmend relevanter werdendes Thema in der Pflegepraxis dar. Trotz großer Aufmerksamkeit hierfür kann eine nur langsam voranschreitende Durchdringung von Pflegetechnologien in der Praxis attestiert werden. In diesem Beitrag wird die Auswahl und Einführung von Pflegetechnologien in akut- und langzeitstationären Einrichtungen der pflegerischen Versorgung als kritische Phase betrachtet, die es bewusst zu gestalten gilt und deren Umsetzung über das Scheitern oder den Erfolg der Nutzung von Pflegetechnologie in der Praxis entscheidet. Die Erfahrungen der Autorinnen und Autoren, die als Forschende im BMBF-geförderten Cluster „Zukunft der Pflege" an der Einführung und Erprobung von Pflegetechnologien in kooperierenden Praxiseinrichtungen beteiligt sind, werden dazu aufgearbeitet und diskutiert.

In edge/fog computing infrastructures, the resources and services are offloaded to the edge and computations are distributed among different nodes instead of transmitting them to a centralized entity. Distributed Hash Table (DHT) systems provide a solution to organizing and distributing the computations and storage without involving a trusted third party. However, the physical locations of nodes are not considered during the creation of the overlay which causes some efficiency issues. In this paper, Locality aware Distributed Addressing (LADA) model is proposed that can be adopted in distributed infrastructures to create an overlay that considers the physical locations of participating nodes. LADA aims to address the efficiency issues during the store and lookup processes in DHT overlay. Additionally, it addresses the privacy issue in similar proposals and removes any possible set of fixed entities. Our studies showed that the proposed model is efficient, robust and is able to protect the privacy of the locations of the participating nodes.

Mobility management is a key feature of mobile edge
computing. We present an edge cloud infrastructure testbed to
explore various mobility scenarios. The design objection of this testbed has been a flexible open platform based on commodity hardware that can easily be scaled with more edge devices and compute resources to perform various edge cloud experiments. As first experiments on our testbed, we have investigated the feasibility of task migration among edge devices caused by edge device overload and unpredictable user movements. We describe the migration process and present some measurements to demonstrate the feasibility.

While the number of devices connected together as the Internet of Things (IoT) is growing, the demand for an efficient and secure model of resource discovery in IoT is increasing. An efficient resource discovery model distributes the registration and discovery workload among many nodes and allow the resources to be discovered based on their attributes. In most cases this discovery ability should be restricted to a number of clients based on their attributes, otherwise, any client in the system can discover any registered resource. In a binary discovery policy, any client with the shared secret key can discover and decrypt the address data of a registered resource regardless of the attributes of the client. In this paper we propose Attred, a decentralized resource discovery model using the Region-based Distributed Hash Table (RDHT) that allows secure and location-aware discovery of the resources in IoT network. Using Attribute Based Encryption (ABE) and based on predefined discovery policies by the resources, Attred allows clients only by their inherent attributes, to discover the resources in the network. Attred distributes the workload of key generations and resource registration and reduces the risk of central authority management. In addition, some of the heavy computations in our proposed model can be securely distributed using secret sharing that allows a more efficient resource registration, without affecting the required security properties. The performance analysis results showed that the distributed computation can significantly reduce the computation cost while maintaining the functionality. The performance and security analysis results also showed that our model can efficiently provide the required security properties of discovery correctness, soundness, resource privacy and client privacy.
