Objectives FHIR (Fast Healthcare Interoperability Resources) is an emerging Stan¬dard for improving interoperability in the domain of health care. Besides offering features for achieving syntactical, semantical and organizational interoperability, it also specifies a RESTful API for searching purposes. The main objective of the following thesis revolves around investigating open challenges and limitations of the so-called FHIR Search Framework.
Methods A variety of operations for searching in FHIR resources, including all search interactions, definitions of search parameters, search parameter types and advanced search concepts are described. Over the course of the thesis, a quality model based on ISO 25010 is established. It serves as the foundation for determining if the FHIR Search Framework is well-suited to cover the Information needs of its users. An analysis of completeness involving the measures defined in the quality model forms the main contribution. The primary discussion of the research questions is concluded by proposing a graph model for determining reachability between FHIR resources, essentially mirroring the chaining and reverse chaining functionality. Using well-known classes for expressiveness in graphs, the thesis assess to which degree a graph search can be formulated with the currently defined capabilities.
Results From a functional perspective the FHIR Search Framework can be considered well-suited. Practical limitations should be minimal, grounded on the fact that extensive coverage of the lowest expressiveness classes, RPQs and 2RPQs, can be achieved. Severe gaps where identified only in the support of C(2)RPQs and Data Path Queries. Additionally, ideas for improving non-functional aspects are introduced to support developers in learning the Standard and testing their implementations.
Conclusion The evaluation of the FHIR Search Framework showed promising re¬sults in terms of functional completeness. Yet, the Standard is still evolving, and certain parts of the Search API are neither well-known nor implemented widely. A discussion is to be held if the specification should cover more sophisticated aspects that result from the gaps which were identified.
Die Analyse von Log-Dateien als Spezialfall des Text Mining dient in der Regel dazu Laufzeitfehler oder Angriffe auf ein Systems nachzuvollziehen. Gegen erkannte Fehlerzustände können Maßnahmen ergriffen werden, um diese zu vermeiden. Muster in semi-strukturierten Log-Dateien aus dynamischen Umgebungen zu erkennen ist komplex und erfordert einen mehrstufigen Prozess. Zur Analyse werden die Log-Dateien in einen strukturierten Event-Log (event log) überführt. Diese Arbeit bietet dem Anwender ein Werkzeug, um häufige (frequent) oder seltene (rare) Ereignisse (events), sowie temporale Muster (temporal patterns) in den Daten zu erkennen. Dazu werden verschiedene Techniken des Data-Minig miteinander verbunden. Zentrales Element ist dieser Arbeit das Clustering. Es wird untersucht, ob durch Neuronale Netze mittels unüberwachtem Lernen (Autoencoder) geeignete Repräsentationen (embeddings) von Ereignissen erstellt werden können, um syntaktisch und semantisch ähnliche Instanzen zusammenzufassen. Dies dient zur Klassifikation von Ereignissen, Erkennung von Ausreißern (outlier detection), sowie zur Inferenz einer nachvollziehbaren visuellen Repräsentation (Regular Expressions; Pattern Expressions). Um verborgene Muster in den Daten zu finden werden diese mittels sequenzieller Mustererkennung (Sequential Pattern Mining) und dem auffinden von Episoden (Episode Mining) in einem zweiten Analyseschritt untersucht. Durch das Pattern Mining können alle enthaltenen Muster im einem Event-Log gefunden werden. Der enorme Suchraum erfordert effiziente Algorithmen, um in angemessener Zeit Ergebnisse zu erzielen. Das Clustering dient daher ebenfalls zur Reduktion (pruning) des Suchraums für das Pattern Mining. Um die Menge der Ergebnisse einzuschränken werden verschiedene Strategien auf ihre praktische Tauglichkeit hin untersucht, um neue Erkenntnisse zu erlangen. Zum einen die Mustererkennung mittels verschiedener Kriterien (Constrained Pattern Mining) und zum anderen durch die Nützlichkeit (High Utility Pattern Mining) von Mustern. Interessante temporale Muster können auf anderen Log-Dateien angewendet werden, um diese auf das Vorkommen dieser Muster zu untersuchen.
Das Internet of Things (IoT) ist aktuell eines der trendgebenden Themen der Infor-mationstechnik. Dem Thema werden dabei viele Versprechungen, aber auch Erwar-tungen auf staatlicher, wirtschaftlicher und alltäglicher Ebene zugeordnet. Dabei besteht die Frage, was ist Hype und was ist Realität? Motivation und Zielsetzung dieser Arbeit ist es, dieses Thema zu untersuchen und Aspekte daraus in einem Smart Home System umzusetzen. Klare Zielsetzung ist die lauffähige Ver-sion eines Prototyps zu produzieren. Dieser soll den technischen Durchstich ver-schiedener Werkzeuge, Technologien und Services, als integratives Ziel dieser Arbeit, durchführen. Eine Verknüpfung mit realen Anwendungsfällen ist zur besse-ren Veranschaulichung wünschenswert, aber für die Zielerreichung nicht zwangsläu-fig erforderlich. Gleichzeitig soll der Prototyp ein stabiles Fundament für weitere Entwicklungen auf dessen Basis bereitstellen. Der Einsatz von Technologien im Be-ta-Stadium ist dadurch aber nicht ausgeschlossen, wie der Einsatz des aktuell noch in der Entwicklervorschau befindlichen Android Things zeigt.
Since the development of eGovernment systems is gaining worldwide momentum, the European Union is constantly increasing its efforts to induce the development of eGovernment systems in its member states. The currently running strategy is the ’eGovernment Action Plan 2016-2020’, which understands itself as a catalyst for developments in the member states.
Despite these ongoing efforts by the European Union regarding eGovernment, stud- ies are repeatedly revealing that the quality and acceptance by the citizens of dig- ital public services are varying heavily within the EU. Being based on the same political guidelines provided by the EU, the national strategies implemented the core principles to different degrees. These different implementation rates, analyzed for Germany, the United Kingdom and Estonia, supplement the holistic analysis of the eGovernment policies, applications and usage in each member state. This gets proven by the connection of this indicator with related studies in the field of eGov- ernment applications and usage within the European Union.
The aim of this thesis is, on the one hand, to quantify differences in the implementa- tion of the ’eGovernment Action Plan 2016-2020’ into national policies in Germany, the UK and Estonia and, on the other hand, establish this indicator as a valuable asset for evaluating and monitoring the eGovernment efforts by the EU member states.
Food insecurity, poor nutrition and poverty are closely linked and entail adverse consequences for the health and well-being of children and adults. They constitute major constraints to development efforts as they can imply lifelong negative effects on human development with impairments on physical and mental capacities of a population, resulting in an overall lower productivity and economic growth potential.
Urban agriculture has been advocated as a strategy to improve food security. This paper exemplifies an urban gardening project that addresses food security and economic resilience of the Syrian refugees and vulnerable Lebanese host communities executed in the suburbs of Beirut. The hypothesis underpinning this study is that urban agriculture holds the potential to contribute to increased food security and reduced urban poverty, by increasing the availability and accessibility to a variety of fresh foods that are rich in vital nutrients and by functioning as a source of livelihoods and income.
The brutality of the Syrian Civil War, it’s massive damage and destruction of housing and persecutions for ethnic cleansing led more than a quarter of its originally 24 million inhabitants to seek safety in neighboring countries and Europe. The war has severely hampered the stability and development throughout the region as hundreds of thousands of refugees have fled to neighboring countries where they often compete with host communities over housing, labor, water, food and land. In relative numbers the biggest burden fell on the riparian country Lebanon, currently holding the highest ratio of refugees to nationals in the world. The small Arab country has already been suffering from many pre-existing challenges as food insecurity and widespread poverty.
The high dependence on food assistance, limited access to income and uncertainties on the amount of food aid provided in each upcoming year, all contribute to an unstable and low food security status of Syrian refugee households in Lebanon with spill overs to vulnerable host communities. In 2017, 91% of Syrian families residing in Lebanon remained food insecure to some degree and the share of household’s falling into severe food insecurity keeps increasing with every year.
These numbers provide clear evidence that current efforts of providing food assistance are not sufficient to combat the repercussions of the crisis and get the situation under control.
The paper displays the impact of the urban gardening project on the food security and economic resilience of participating household’s, as well as lessons learned on the project design during and after the implementation phase. The sampling frame is comprised of Syrian and Lebanese families participating in the project. Primary data were derived from a survey using a questionnaire with a sample size of 41 households. The findings aim to enable stakeholders to improve the performance of similar projects in the future and support relevant government authorities, international aid institutions, non-profits and the civic society towards creating sustainable long-term solutions to increase the self-reliance of refugees by providing insights of the suitability of UA for multiple objectives and by highlighting potential challenges and risks.
Domänenspezifische Sprachen gewinnen seit einigen Jahren zunehmend an Bedeutung. Xtext ist eine sogenannte \textit{Language Workbench}, mit der solche Sprachen schnell entwickelt werden können. Neben der Sprachinfrastruktur wird eine inzwischen weit fortgeschrittene Integration in die IDE Eclipse erzeugt und es können optional ein Plug-in für IntelliJ und ein Webeditor erstellt werden. Der Ansatz ist dabei, dass der oder die Codegeneratoren direkt mit dem Abstract Syntax Tree arbeiten. In dieser Arbeit wird gezeigt, wie ein Domänenmodell in eine Xtext-Sprache integriert werden kann und wie Test- und Wartbarkeit davon profitieren. Besondere Beachtung finden, gegeben durch das Projektumfeld, die Anforderungen durch Funktionale Sicherheit.
Urban settlements demand the highest levels of resource consumption and waste management.
It has been accepted that cities should be considered organisms. Through Urban Energy Metabolism the planning and management of energy that flows across cities achieves important developments towards sustainability. Energy Efficiency is one of the primary tools used to produce sustainable development. Cities worldwide are developing action plans that implement the teachings of holism and eco-friendly practices. Systems Theory is a field developed with the intention of managing systems based on interdisciplinarity and a holistic approach. Fundamental practices of systems thinking are applicable to the study of cities as sustainable organisms/complex systems. Planning for Energy Efficient Cities (PLEEC) is an European project that was executed by a group of participants from the public, private, and education sectors, with the purpose of designing energy efficiency action plans to meet the targets of 2020. This work introduces, based on a literature review, several systems theories. A critique of the characteristics of PLEEC’s framework is performed to assess the level of systemic consideration into holism and sustainability. The evaluation of the process or success of the energy efficiency plans elaborated is not in the scope of the research. Using a modified version of Michael C.
Jackson’s Total Systems Intervention and a table that summarizes the principles of systems thinking, it is concluded that the plan lacks systemic consideration of cities as complex systems. The framework includes several concepts attributed to the field, such as interconnection of elements exchanging information and resources, but fails in defining self-organizing feedback based structures and function-driven behavior. It is of paramount importance that system thinking basics be at the core of all planning.
Zijad Naddaf fragt danach, wie sich Grenzen und die darin eingelagerte Erzählung von Flucht und Migration durch Praktiken und Diskurse formieren. Vor dem Hintergrund der Flüchtlingszuwanderung und mit Bezug auf Foucault werden Gesamtstrategien der Europäischen Union zur ‚Verteidigung ihrer Gesellschaft‘ diskutiert, unter anderem am Beispiel der Grenzbearbeitungsagentur Frontex konkretisiert sowie das Konstrukt der Europäischen Union als Ordnung herstellendes Dispositiv vorgestellt. Mit Bezug auf solche Formierungen werden die Wege der Fliehenden zu einem Kampffeld, in dem sich sowohl die Autonomie von Migration als auch die beständigen und repressiven Weg- und Raummarkierungen zeigen, die sich bis auf das Meer ausdehnen.
Grundlegend wird in dieser Masterarbeit der Frage nachgegangen, welche Anspruchsvoraussetzungen Versicherte nach der Integration des Gesetzes zur Verbesserung der Hospiz- und Palliativversorgung (HPG) erfüllen müssen, um eine Palliativversorgung zu erhalten. Über die definitorische Unschärfe des Beginns und weiteren Verlaufs des Sterbens werden das Risiko der Ungleichbehandlung aufgezeigt und die Konsequenzen für die Soziale Arbeit abgeleitet.
With a rapidly growing population and urbanization, most modern slums (favelas) also proliferated in Brazil since the 1950s when many people left rural areas of Brazil and moved into the cities. Rio de Janeiro is one of those cities having a vast amount of favelas with poor living conditions. One of the main problems of electricity supply in favelas is illegal electricity use, called ‘Gato’ in Portuguese. Recent unexpected severe drought, economic crisis, and rapidly increased electricity price in Brazil affected the reliable supply of affordable electricity in favelas.
Considering abundant solar radiation of the country and the government’s willingness trying to shift the framework of energy supply from hydropower to renewable energy, this study analyzes the solar PV potentials to ensure a reliable supply of affordable electricity in favelas in Rio de Janeiro.
Literature reviews regarding solar PV development in Brazil, energy policy analysis in Brazil and electricity issues in favelas are revised. As a case study, the chosen favela ‘Babilônia’ is presented. The survey analysis about electricity consumption situation with social dimension targeting residences in Babilônia is implemented. Lastly, through economic analyses with cost-benefit calculation such as Internal Rate of Return (IRR), Net Present Value (NPV), Discounted Cash Flow, Payback period, Capital Asset Pricing Model (CAPM) and Weighted-Average Cost of Capital (WACC) models, this study develops the possible financing alternatives to implement a solar PV project with different scenario analyses in the current solar PV market and solar energy policy of Brazil.
The results of this study can be used as an aid to comprehend the electricity supply issue of the most vulnerable class in Brazil and the solar PV as a solution.
