Therefore an innovative educational project teaching fundamental concepts of AI at high school level will be presented in this paper. We developed an AI-course covering major topics (problem solving, search, planning, graphs, datastructures, automata, agent systems, machine learning) which comprises both theoretical and hands-on components. A pilot project was conducted and empirically evaluated. Results of the evaluation show that the participating pupils have become familiar with those concepts and the various topics addressed. Results and lessons learned from this project form the basis for further projects in different schools which intend to integrate AI in future secondary science education.

The digitalization of business processes of manufacturing companies offers enormous potentials in terms of productivity. Nevertheless, the digitalization level of SMEs is low compared to large enterprises, as SMEs lack in resources in terms of time, money, and personnel. Another reason is, that SMEs are lacking in qualified workforce for the digital transformation. Learning factories and makerspaces offer valuable learning environments to transfer competencies for the digital transformation and digitalization. In this paper the results of an interview study with SMEs are presented that included the investigation of required competencies of the workforce in this field. Moreover, the didactical transfer of one of the required competencies is shown and implications for trainings in learning factories and makerspaces are derived. In conclusion a structur...

Documents corresponding to the Clinical document architecture (CDA) R2 laboratory reports standard and a rapid prototyping framework called Groovy on Grails were used. This work shows, that it is possible to create a useful, standards based tool for patients and physicians with comparatively few resources - an application that could be in similar form a part of an electronic Health Record (EHR) system like the Austrian electronic Health Record (ELGA).

This is especially true in case of mass-casualty incidents. Therefore, the aim of this work was to investigate if and to what extent the dispatch operation of the Red Cross Salzburg can be optimized on such occasions with a computerized system. The basic problem of a dynamic multi-vehicle Dial-a-Ride Problem with time windows was enhanced according to the requirements of the Red Cross Salzburg. The general objective was to minimize the total mileage covered by ambulances and the waiting time of patients. Furthermore, in case of emergencies suitable adaptions to a plan should be carried out automatically. Consequently, the problem is solved by using the Adaptive Large Neighborhood Search. Evaluation results indicate that the system outperforms a human dispatcher by between 2.5% and 36% within 1 minute of runtime concerning total costs. Moreover, the system's response time in case that a plan has to be updat...

A smartwatch-based assistance system should be implemented that is capable of automatically detecting emergencies and helping elderly people to adhere to their medical therapy. Using the acceleration data of a widely available smartwatch, we implemented fall detection and inactivity recognition based on a smartphone connected via Bluetooth. The resulting system is capable of performing fall detection, inactivity recognition, issuing medication reminders and alerting relatives upon manual activation. Though some challenges, like the dependence on a smartphone remain, the resulting system is a promising approach to help elderly people as well as their relatives to live independently and with a feeling of safety.

To guarantee affordable health care, AAL (Ambient Assisted Living) is one possibility. Our objective is to show that it is possible to create remote support for caregivers by physicians even with widely available and versatile hardware. A single board computer currently only equipped with 6 different sensors to measure blood pressure, glucose level, pulse, oxygen saturation, temperature and ECG is used as a showcase for patients with e.g. coronary artery disease. We created a user-friendly local application that collects and stores all data and transmits them to a remote server as soon as an Internet connection becomes available. Additionally, a web-application gives access to remote physicians and nurses to support caregivers and patients. Patients keep the overview of their vital signs, caregivers, nurses and physici...

Clinical decisions require experience and continuous learning processes to consolidate personal values and opinions and studies suggest that lecturers can influence students positively. Recently, the study course of Physiotherapy at the University of Applied Science in Graz has offered a paper based finding document. This document supported decisions through the adaption of the clinical reasoning process. The document was the starting point for our learning application called "EasyAssess", a Java based web-application for a digital findings documentation. A central point of our work was to ensure efficiency, effectiveness and usability of the web-application through usability tests utilized by both students and lecturers. Results show that our application fulfills the previously defined requirements and can be effic...

This is due to the acute and serious, often life-threatening illness of the patients and the very complex and technical environment of an intensive care unit (ICU). Unmet needs for information can increase anxiety, sleep disorders, stress, and depressive symptoms in the relatives. The potential of the ICU families website in terms of usability and functionality during real-time testing were evaluated. The ICU families project created a dynamic online information platform in the form of a password-protected website. It contains pictures, written explanations, 5 movies, a forum and a diary function. The usability of the website was tested among 10 lay people and 10 experts (7 nurses and 3 physicians) according to the Think Aloud Method. The outcome is qualitative feedback based on video documentation by laypeople and suggestions by experts. Criticisms mentioned by the test subjects were insufficient image mate...

Especially visual examination of bone marrow cells takes a considerable amount of time and inter-observer variability can be remarkable. In this work, we propose a novel rotation-invariant learning scheme for multi-class Echo State Networks (ESNs), which achieves very high performance in automated bone marrow cell classification. Based on representing static images as temporal sequence of rotations, we show how ESNs robustly recognize cells of arbitrary rotations by taking advantage of their short-term memory capacity.

We used these characteristics to develop a framework with which it is possible to rapidly develop and deploy secure mobile applications in the Austrian eHealth context. We implemented mechanisms to be able to securely connect and process medical data according to current legal regulations via a secured communication server acting as a relay between mobile devices and the protected data storage. Additionally, the development of new applications is reduced to the writing of a single configuration file.

We evaluated whether exercises can also be telemonitored. To make this technology affordable, cheap sensors are necessary. Literature suggests the use of gaming console sensors, but no validation of sensor accuracy and a usage for real exercises could be found. With a study with patients we found out, that these sensors can indeed be used under certain restrictions about positioning, fixation and types of exercise. It can be detected remotely whether patients do exercises correctly or not.
