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.
Biomedizinische Statistik
(2024)
Die klassische konfirmatorische Statistik, auch frequentistische Statistik genannt, setzt voraus, dass man theoretisch unendlich viele Stichproben ziehen kann, und dass dann die aus den Stichproben berechnete Prüf- oder Testgröße unter der Nullhypothese H0 eine bestimmte Verteilung annimmt. Meistens sind die Testgrößen so konstruiert, dass bei Ziehung der Stichproben aus immer derselben Grundgesamtheit (es gilt die Nullhypothese H0) eine Verteilung der Testgröße um den Wert null herum entsteht, z.B. in Form einer Glockenkurve, d.h., kleine Werte überwiegen. Große Werte der Prüf- oder Testgröße kommen mit geringer Wahrscheinlichkeit vor und signalisieren einen möglichen Ausnahmefall. Statt anzunehmen, dass einer der seltenen Fälle einer großen Prüfgröße eingetroffen ist, nimmt man lieber an, dass sich die Grundgesamtheiten unterscheiden (Alternativhypothese HA).

The Present and Future of a Digital Montenegro: Analysis of C-ITS, Agriculture, and Healthcare
(2023)
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.

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.
The impact of store atmosphere elements on the purchase behaviour and emotions of customers has an important significance in modern marketing. How to design and conceptualize a store atmosphere in such a way that it provides an unforgettable experience for the customer and entices him or her to arouse an interest in the store environment is one of the most fundamental concerns merchants and marketers must ask and think through these days – likewise, the role of culture in connection with store atmosphere is necessary to understand. The goal of this paper is to answer the question on how behavioural and emotional responses to store atmospheric elements such as visual, aural, olfactory, tactile, social, exterior design, interior design and layout & design differ across individualist and collectivist cultures. A cross-cultural analysis between Germans and non-Germans is made in respect to the posed question. A quantitative online survey was conducted, in which a total of 99 valid participants took part, of which 57 were Germans and 42 were non-Germans. This research extended the study of Barros et al. (2019) and added two more separate store atmospheric elements which are the general exterior design and the general interior design. The data was then analyzed, and the findings were ultimately presented. The findings showed that overall store atmosphere elements have similar emotional and behavioural effects on individualist and collectivist cultures with the exception of the general exterior design element, where a significant difference was found. This paper gives a comprehensive overview on the importance of store atmospheric elements in retail and the comparison between Germany which acts as a country that scored relatively high on the Individualism dimension of Hofstede’s national culture model and the countries Turkey, Russia, Portugal, Albania, Bosnia, Romania, Kazakhstan, Vietnam, Sri Lanka and Iraq which serve as a union of cultures that performed high on the Collectivism dimension. Additional research on the topic needs to be done on how culture affects shopper’s emotional and behavioural responses.
This study explores the complex dynamics influencing the establishment of secondary
vocational exchange programs, with an emphasis on identifying the barriers and
facilitators in this process. Adopting a qualitative research approach, the study seeks to
capture the rich, nuanced experiences of stakeholders and provide context-specific
insights. Semi-structured interviews were conducted with professionals, administrators,
and officials associated with German and United States Vocational Education. Employing
a two-tiered participant selection strategy, a range of perspectives were captured. The
data were analyzed using an inductive approach to thematic analysis, aiming to identify
underlying patterns and themes. Preliminary findings indicate that funding, policy and
governance challenges, educational structures, administrative elements, corporate
attitudes, and socio-cultural influences play significant roles in the establishment of these
exchange programs. The research also underscores the importance of participant
preparedness, program structure, stakeholder interest and engagement, diversity and
inclusion, and innovative program approaches as vital facilitators. These insights can
influence the development of policies and practices for future secondary vocational
exchange programs, thus contributing meaningfully to the larger conversation
surrounding vocational exchange programs and international educational partnerships.
Jährlich sterben etwa 3.000 Menschen bei Verkehrsunfällen in Deutschland. Trotz technischen Fortschrittes der Fahrzeuge und steigender Sicherheit im Straßenverkehr nimmt die Anzahl an Verkehrstoten nur minimal ab. Im Vergleich zu 1950 hat die Zahl an zugelassenen PKW in Deutschland deutlich zugenommen. Um die Anzahl der Todesfälle zu verringern, wurde durch die Europäische Union das 112-eCall Notrufsystem für alle PKW und leichten Nutzfahrzeugen mit einer vollen Typenzulassung ab dem 31.03.2018 verpflichtend eingeführt. Öffentliche Notrufleitstellen sowie der ADAC klagen über häufige Probleme mit dem eCall System. Fahrzeughersteller und andere Firmen dürfen auch ein eigenes eCall Angebot anbieten, wenn gewisse Bedingungen erfüllt sind. Bei Verkehrsunfällen ist eine schnelle Rettung und Transport in ein geeignetes Traumazentrum maßgeblich dafür verantwortlich, welche Überlebenschancen die verletzte Person hat. Ziel dieser Arbeit ist es, die verschiedenen eCall Arten anhand von Leitstellendaten zu untersuchen und zu ermitteln, wie viele dieser Einsätze in den Leitstellen eingegangen sind. Es sollen außerdem die Qualität und die Unterschiede der beiden Systeme in einer örtlichen Analyse ermittelt werden.
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.
