Indirekte Steuerung und Stressbewältigung in der Arbeitswelt 4.0

Die Arbeitswelt 4.0 birgt Chancen wie mehr Selbstbestimmung und bessere Vereinbarkeit von Beruf und Familie, aber auch Risiken wie psychische Überlastung und interessierte Selbstgefährdung, besonders in Organisationen mit indirekter Steuerung. Digitale Lösungen können eine wichtige Rolle bei der Stressbewältigung spielen und klassische BGM-Maßnahmen ergänzen.

In particular, the increasing usage of (deep) neural nets and the resulting black-box algorithms has led to wide-spread demands for explainability. Apart from discussing how explainability might be achieved, the paper also looks at other approaches at building trust such as certification or controlling bias. Trust is a crucial prerequisite for the use and acceptance of AI systems in the medical domain.

Eine Verbesserung lässt sich erzielen, wenn Dokumentinhalte unter Verwendung einer Terminologie oder gar einer Ontologie explizit beschrieben sind, so dass Suchanfragen auf diesen inhaltsbeschreibenden Strukturen ausgewertet werden, anstatt (nur) auf der Textoberfläche. Der Beitrag stellt zwei unterschiedliche Anwendungen vor, wo die Beschreibung und das Auffinden von Informationen erst durch den Einsatz von Terminologien praktikabel wurden.

An online survey was conducted in Austria, Germany and Switzerland to find out managers' attitudes towards experience and if and how they capture, use and disseminate it. The results show that the majority consider experience an important asset, but do not actually support it in any systematic way. Company size and position rather than age or gender play a role when it comes to preferences, attitudes or practices. The survey shows great discrepancies between methods considered useful vs. those in regular use. Besides, there is a preference for classical people-oriented methods rather than modern IT-supported methods. Integrating experience management into project and process management practice may help overcome current barriers and reservations.

Furthermore, due to increasing competi-tion on the market there is a strong pressure to increase efficiency and quality of office task per-formance. The only way to meet these manifold requirements is to provide a computer-based guid-ance and interactive support for office workers. At Swiss Life, we have developed the EULE system which fulfills these requirements. EULE’s func-tionality is in the triangle of Knowledge Repre-sentation, Business Process Modeling, and Knowl-edge Management- the latter because EULE en-codes and stores knowledge which is crucial for the company. The system relies on a knowledge rep-resentation language which covers data and pro-cess aspects as well as the relevant legislation and company regulations.

A central contribution is the automatic calibration of measured HRV values to perceived stress levels during an initial learning phase where the user provides feedback when prompted by the system. This is crucial as HRV varies greatly among people. A data mining component identifies recurrent stress situations so that people can develop appropriate stress avoidance and coping strategies. A biofeedback component based on breathing exercises helps users relax. The solution is being tested by healthy volunteers before conducting a clinical study with patients after alcohol detoxification.

Earlier approaches to AI were primarily associated with the knowledge-based paradigm where systems include domain-specific knowledge bases that provide the required (background) knowledge. The construction and maintenance of such domain models has to be done largely manually and therefore requires a great deal of time and money, which is why these approaches scale up poorly.

A pair of downwardly concave shouldered portions on the base support a pair of downwardly depending legs on the lower mounting plate, so formed to permit limited relative pivotal movement between the base and plate in a vertical plane. The base and lower mounting plate are further formed to be both insertable through the mounting aperture in the support surface from the exterior thereof. The lower mounting plate and upper mounting means are adapted to be clamped to the support surface by a nut threaded on the upper portion of the base. The nut is formed with a hemispherical lower portion and the upper mounting means is formed with a co...

To this end, the paper gives concise introductions into the terminological logic FRM and the object data model COCOON. It then brieey outlines a mapping from FRM class descriptions to COCOON types and classes and shows how the terminological inference of classiication is mapped to a set of equivalent COCOON queries. Since these queries can (mostly) be submitted as a whole to the underlying database system we can take full advantage of all the results on query optimisation, on providing eecient physical access structures, as well as on parallelisation that are available in the database area to make terminological inferences more eecient. This can play a crucial role in realising knowledge base systems capable of dealing with very large knowledge bases.

This brings the demand to create or adapt domain-specific modeling languages (DSMLs) efficiently and in a timely manner, which, on the contrary, is a complex and timeconsuming engineering task. This is not just due to the required high expertise in both knowledge engineering and targeted domain. It is also due to the sequential approach that still characterizes the accommodation of new requirements in modeling language engineering. In this paper we present a DSML adaptation approach where agility is fostered by merging engineering phases in a single modeling environment. This is supported by ontology concepts, which are tightly coupled with DSML constructs. Hence, a modeling environment is being developed that enables a modeling language to be adapted on-the-fly. An initial set of operators is presented for the rapid and efficient adaptation of both syntax and semantics of modeling languages. The approach allows modeling languages to be quickly released for usage.
