Orchestrating Heterogeneous Devices and AI Services as Virtual Sensors for Secure Cloud-Based IoT Applications.

The concept of the cloud-to-thing continuum addresses advancements made possible by the widespread adoption of cloud, edge, and IoT resources. It opens the possibility of combining classical symbolic AI with advanced machine learning approaches in a meaningful way. In this paper, we present a thing registry and an agent-based orchestration framework, which we combine to support semantic orchestration of IoT use cases across several federated cloud environments. We use the concept of virtual sensors based on machine learning (ML) services as abstraction, mediating between the instance level and the semantic level. We present examples of virtual sensors based on ML models for activity recognition and describe an approach to remedy the problem of missing or scarce training data. We illustrate the approach with a use case from an assisted living scenario.

[Assessment center--a suitable method for student selection in nursing schools]. / Assessment center--eine geeignete methode zur bewerberauswahl an krankenpflegeschulen?

For a valid selection of applicants it is necessary to identify the specific abilities and personal characteristic which are required by the profession or education program. Until now, the selection procedures used in nursing colleges are merely based on psychological knowledge regarding personnel selection and proved methods to diagnose the suitability for profession. To fill in this gap in choosing nursing students, the common selection procedures have been proved and a procedure using elements of Assessment Centers has been developed. Assessment Center methods offer several advantages both to the applicants and nursing colleges. Applicants can become aware of their strengths and weaknesses, and can use these results for their further development. On the other hand, the probability rises, that applicants chosen for the nursing training fulfil the professional requirements and will successfully pass the education program.

Fractura de segundo metacarpiano derecho con luxación corpometacarpiana de segundo, tercer, cuarto y quinto metacarpianos: comunicación de un caso / A metacarpal fracture together with carpometacarpal dislocation of 4 fingers is a rare event in the orthopaedic praxis

Se comunica un caso de fractura de un metacarpiano y luxación carpometacarpiana de cuatro articulaciones en una misma mano. Considerando lo infrecuente de estas lesiones en forma simultánea, se revisa la anatomía de la mano, el tratamiento quirúrgico y la importancia de la rehabilitación precoz
