Course of studies
Introduction: The present study investigated the role of training intensity in the dose–response relationship between endurance training and cardiorespiratory fitness (CRF). The hypothesis was that beginners would benefit from an increase in training intensity after an initial training phase, even if the energy expenditure was not altered. For this purpose, 26 weeks of continuous moderate training (control group, CON) was compared to training with gradually increasing intensity (intervention group, INC) but constant energy expenditure.
Methods: Thirty-one healthy, untrained subjects (13 men, 18 women; 46±8 years; body mass index 25.4 ± 3.3 kg m−2; maximum oxygen uptake, VO2max −1 −1 34 ± 4 ml min kg ) trained for 10 weeks with moderate intensity [3 days/week for 50 min/session at 55% heart rate reserve (HRreserve)] before allocation to one of two groups. A minimization technique was used to ensure homogeneous groups. While group CON continued with moderate intensity for 16 weeks, the INC group trained at 70% HRreserve for 8weeks and thereafter participated in a 4 × 4 training program (high-intensity interval training, HIIT) for 8 weeks. Constant energy expenditure was ensured by indirect calorimetry and corresponding adjustment of the training volume. Treadmill tests were performed at baseline and after 10, 18, and 26 weeks.
Results: The INC group showed improved VO2max (3.4 ± 2.7 ml kg−1 min−1) to a significantly greater degree than the CON group (0.4 ± 2.9 ml kg−1 min−1) (P = 0.020). In addition, the INC group exhibited improved Vmax (1.7 ± 0.7 km h−1) to a significantly greater degree than the CON group (1.0 ± 0.5 km h−1) (P = 0.001). The reduction of resting HR was significantly larger in the INC group (7±4bpm) than in the CON group (2±6bpm) (P=0.001). The mean heart rate in the submaximal exercise test was reduced significantly in the CON group (5±6bpm; P=0.007) and in the INC group (8±7bpm; P=0.001), without a significant interaction between group and time point.

In this paper, we present a study on the utilization of smart medical wearables and the user manuals of such devices. A total of 342 individuals provided input for 18 questions that address user behavior in the investigated context and the connections between various assessments and preferences. The presented work clusters individuals based on their professional relation to user manuals and analyzes the obtained results separately for these groups.
Health informatics plays a crucial role in modern healthcare provision. Training and continuous education are essential to bolster the healthcare workforce on health informatics. In this work, we present the training events within EU-funded DigNest project. The aim of the training events, the subjects offered, and the overall evaluation of the results are described in this paper.
This poster presents a Montenegrin Digital Academic Innovation Hub aimed to support education, innovations, and academia-business cooperation in medical informatics (as one of four priority areas) at national level in Montenegro. The Hub topology and its organisation in the form of two main nodes, with services established within key pillars: Digital Education; Digital Business Support; Innovations and cooperation with industry; and Employment support.
Akademisch qualifizierte Pflegefachkräfte sind prädestiniert dafür, erweiterte Rollen, Aufgaben und Spezialisierungen im Versorgungsgeschehen zu übernehmen. Ziel einer solchen Neuausrichtung in der Pflege ist es, Patienten*innen, Bewohner*innen in Pflegeeinrichtungen und Bürger*innen eine medizinisch-pflegerische Versorgung auf qualitativ hohem Niveau zukommen zu lassen. Dazu gehört auch die Sicherung und Verbesserung der Versorgungsqualität. Die erweiterte und fortgeschrittene Pflegepraxis durch akademisch qualifizierte Pflegefachkräfte in spezifischen Versorgungsbereichen bewährt sich seit vielen Jahren z.B. in den angelsächsischen oder skandinavischen Ländern und wird auch in Deutschland bereits an bestimmten Standorten umgesetzt. Dennoch sind zukünftige Handlungsfelder, Aufgaben- und Verantwortungsbereiche von akademisch ausgebildeten Pflegefachkräften unzureichend erprobt und strukturell beschrieben.
Kriterien zukünftiger Aufgaben- und Verantwortungsbereiche akademisch ausgebildeter Pflegefachpersonen in der ambulanten, stationären Langzeitpflege und im Quartier sowie die Ableitung vertraglicher, leistungs- und ordnungsrechtlicher Rahmenbedingungen und Empfehlungen für deren Einsatz sind herausgearbeitet wurden. Konkrete Handlungsempfehlungen für den Einsatz von akademisch ausgebildeten Pflegefachkräften und für die dazu erforderlichen Rahmenbedingungen sind beschrieben und formuliert worden, um so das Verständnis einer erweiterten Pflegepraxis zu fördern.
The common corpus optimization method “stop words removal” is based on the assumption that text tokens with high occurrence frequency can be removed without affecting classification performance. Linguistic information regarding sentence structure is ignored as well as preferences of the classification technology. We propose the Weighted Unimportant Part-of-Speech Model (WUP-Model) for token removal in the pre-processing of text corpora. The weighted relevance of a token is determined using classification relevance and classification performance impact. The WUP-Model uses linguistic information (part of speech) as grouping criteria. Analogous to stop word removal, we provide a set of irrelevant part of speech (WUP-Instance) for word removal. In a proof-of-concept we created WUP-Instances for several classification algorithms. The evaluation showed significant advantages compared to classic stop word removal. The tree-based classifier increased runtime by 65% and 25% in performance. The performance of the other classifiers decreased between 0.2% and 2.4%, their runtime improved between −4.4% and −24.7%. These results prove beneficial effects of the proposed WUP-Model.
Feasibility of Parylene C for encapsulating piezoelectric actuators in active medical implants
(2023)
Parylene C is well-known as an encapsulation material for medical implants. Within the approach of miniaturization and automatization of a bone distractor, piezoelectric actuators were encapsulated with Parylene C. The stretchability of the polymer was investigated with respect to the encapsulation functionality of piezoelectric chips. We determined a linear yield strain of 1% of approximately 12-μm-thick Parylene C foil. Parylene C encapsulation withstands the mechanical stress of a minimum of 5×105 duty cycles by continuous actuation. The experiments demonstrate that elongation of the encapsulation on piezoelectric actuators and thus the elongation of Parylene C up to 0.8 mm are feasible.
Microstructure of Selective Laser Melted 316L under Non-Equilibrium Solidification Conditions

Seit 2021 läuft in Baden-Württemberg das Landesprojekt Hochschulweiterbildung@BW, in dessen Mittelpunkt die strukturelle Weiterentwicklung der wissenschaftlichen und künstlerischen Weiterbildung steht.
Im folgenden Beitrag wird die dritte Säule des Projektes, die Initiierung und Etablierung einer Struktur von Regional-und Fachvernetzungsstellen an den beteiligten Hochschulen, in den Blick genommen. Dieses neue Instrument wird zunächst in seiner Grundstruktur vorgestellt, eine Zwischenbilanz nach Ablauf der ersten Projekthälfte gezogen und dann der Frage nachgegangen, wie die Arbeit der Regional- und Fachvernetzungsstellen dazu beiträgt, die Bedarfe aus Wirtschaft und Gesellschaft und die Weiterbildungsangebote der Hochschulen noch besser in Passung zu bringen.
