Die Ergebnisse zeigen, dass die verschiedenen Methoden aus dem Feld der künstlichen Intelligenz geeignet sind, textbasierte Kommunikation zu analysieren und damit Erkenntnisse für die Evaluation bereitzustellen. Angesichts der riesigen Menge an bestehenden und zukünftigen textbasierten Beratungsinhalten können so die unterschiedlichsten Fragestellungen bearbeitet werden. Da die Datenbasis jedoch immer hochsensible personenbezogene Daten enthält, müssen die entsprechenden Risiken mit einer verantwortungsvollen Umsetzung des Datenschutzes minimiert werden.
Gaming Social Work History
(2021)
OBJECTIVES: The requirements regarding professional social work are constantly increasing. The development of a professional identity, which goes hand in hand with a comprehensive ability to reflect, is only one of the aspects mentioned in the international definition. To this end, the examination of the history of social work during the course of study appears to be meaningful and important for many reasons. THEORETICAL BASE: It is precisely this topic that proves to be particularly complex. Based on the increasing requirements on social work, another attempt is made through analyzing social work history in an overarching framework. METHODS: As important the topic seems to be for professional development, for students the analysis of the history of social work is yet often a necessary evil during undergraduate studies. OUTCOMES: Current study results clarify that students do not have a comprehensive professional identity. SOCIAL WORK IMPLICATIONS: Using the concept of gamification for the imparting of knowledge about the history of social work could be a “game changer”.
Many shift workers suffer from sleep issues, which negatively affect quality of life and performance. Scientifically evaluated, structured programs for prevention and treatment are scarce. We developed an anonymous online cognitive behavioral therapy for insomnia (CBT-I) program. After successful completion of a feasibility study, we now start this prospective, randomized, controlled superiority trial to compare outcomes of two parallel groups, namely an intervention group and a waiting-list control-group. Additionally, we will compare these outcomes to those of a face-to-face CBT-I outpatient sample.
Bone fracture healing is a complex process which is still under research. Computer-aided patient-specific prediction of bone development, fracture risk, prevention and treatment approaches promises a significant milestone in clinical practice. With this long-term goal in mind, a novel model is presented and examined in this work in the context of continuum bone remodelling. Therein, a clear distinction is made between external mechanical stimulation and the biological healing process of an injured bone tissue. The model is implemented within a finite element framework and investigated for the example of a fractured proximal femur head. The results show promising perspectives for further application. Besides, the model offers the possibility of easily integrating other factors like age-dependency and the availability of nutrition. For the future, further studies with large clinical datasets are essential for validation.
Modeling the evolution of bone density is relevant for understanding, simulation and possible prediction of bone response to external and internal influences. In this work we present a formulation for the bone density evolution process that takes into account not only the commonly considered mechanical stimulus, but, as novelty, also the influence of the availability of nutrients and hormones, with its implementation pursued within the finite element method. A simple uni-axial extension test is used to illustrate and compare our novel model against the classical approach. The results of the proposed modified model are promising for application to real-life problems.
The illumination of registration plates poses challenges for lighting technology. To achieve the wide and steep angles required for homogeneous illumination of the license plate, optics are needed to refract and reflect light. In this work, registration plate lamps with different components are designed. After the construction, the concepts are tested for their limits in terms of position and manufacturability. The
entire work is carried out at the company CREAT GmbH in Ingolstadt. All developments in the field of registration plate lighting are subject to the UNECE and country-specific regulations, which must be considered in the development of the lights.[1] Some vehicles currently available on the automotive market are measured to classify and compare the different lamp systems. From the average values, the lamps are designed. Adjustments are repeatedly made to the lighting device to achieve the most
homogeneous illumination of the registration plate. As soon as the lights meet the legal requirements, the geometric limits of the lighting device are defined in relation to the plate. As there are different polymers to produce optics, these are simulated with their refractive indices and tested for their effects on the light image.
Die Corona-Pandemie hat die Hochschulen in eine Krisensituation versetzt. Die damalige Entscheidung, das Sommersemester 2020 trotz Kontaktverboten durchzuführen, hat alle Hochschulen mobilisiert eine nahezu vollständige Online-Lösung aufzubauen. Diese ‹Zwangsdigitalisierung› hat Lehrende und Studierende in den folgenden Monaten in einen Experimentiermodus versetzt. Dass sich Lehrende und Lernende in dieser Breite mit digitalen Technologien auseinandersetzen und Erfahrungen machen, konnten bisherige Forderungen und Förderungen nicht erreichen. Es ist jedoch ungewiss, wie diese Dynamik in den Lehralltag einer Post-Pandemie-Zeit übertragen werden kann. Hier sind Hochschulen auf strategischer Ebene gefragt, den Krisenmodus für den Change-Prozess zu nutzen. Anhand einer Gruppendiskussion mit 14 Vizepräsidentinnen und Vizepräsidenten haben wir untersucht, welche langfristigen Veränderungspotenziale der Pandemie wahrgenommen werden. Durch eine strukturierte Inhaltsanalyse der Diskussion erweitern wir in diesem Beitrag die bisherigen zusammenfassenden Ergebnisse. Die Analyse zeigt, dass als entscheidende Variable für den Erfolg beim Krisenmanagement multiple agile Kooperationsformate zwischen den unterschiedlichen Ebenen und Akteuren wahrgenommen werden. Die Aufrechterhaltung und der Ausbau dieser Kooperationen kann die Grundlage für einen langfristigen Change-Prozess darstellen, der unabhängig von der CoViD-19-Pandemie notwendig ist.
Bone remodelling is a complex biomechanical process, which has been studied widely based on the restrictions of local continuum theory. To provide a nonlocal bone remodelling framework, we propose, for the first time, a peridynamic formulation on the macroscale. We illustrate our implementation with a common benchmark test as well as two load cases of the proximal femur. On the one hand, results of our peridynamic model with diminishing nonlocality measure converge to the results of a local finite element model. On the other hand, increasing the neighbourhood size shows to what extent the additional degree of freedom, the nonlocality, can influence the density evolution.
A number of previous studies have investigated the possibilities of modelling the change in density of bones. Remodeling can be formulated at the constitutive or the kinematic level. In this work we introduce a formulation for the density growth process which takes not only the mechanical stimulus into account but also the influence of age on the evolution of growth. We demonstrate the implementation in the context of the finite element method. This novel approach is illustrated for a simple uniaxial extension test and is verified against previous numerical results. Moreover, two further physiologically motivated examples are performed. The results of the proposed modified model show excellent agreement with comparable results from literature and are promising for the application to real-life problems.
