Experimental Evaluation of Open-Source-based VoNR and OTT Voice Services in 5G SA Network Deployments
No full textThe Fifth Generation (5G) mobile network was developed to provide greater capacity, lower latency, and higher throughput, thereby enhancing multimedia service delivery. In the context of private 5G networks, open-source software is a key enabler of innovation and widespread adoption. This study introduces the first open-source prototype implementation of Voice over New Radio (VoNR) and evaluates its performance in two 5G Standalone (SA) private network deployment models: distributed and all-in-one (”in-a-box”). Leveraging an experimental setup composed entirely of open-source tools, the paper offers a comparative analysis of VoNR and Over-the-Top (OTT) voice services, examining their respective advantages and limitations. The findings contribute to the optimization of voice and multimedia services in next-generation (6G) networks and underscore the role of open-source platforms in achieving scalable, high-quality voice integration
Odnos između kognitivne regulacije emocija i depresije, anksioznosti i stresa kod medicinskih sestara
No full textIntroduction. Numerous studies have shown that
there is significant relationship between nurses’
emotional states and their work performance. This
relationship is particularly significant when symptoms
of distress (depression, anxiety, and stress) are
elevated. Cognitive emotion regulation strategies
that support effective responses to environmental
challenges are termed adaptive, while those that impede
functioning are known as maladaptive.
Aim. To examine mental health of nurses, as measured
by depression, anxiety and stress and to investigate
the contribution of cognitive emotion regulation
strategies to the prediction of depression, anxiety
and stress.
Methods. Data were collected in February 2023 at
Osijek University Hospital. A total of 82 nurses participated
in the study. Data were collected using
sociodemographic questions, the Depression, Anxiety,
and Stress Scale (Lovibond & Lovibond, 1995),
and the Cognitive Emotion Regulation Questionnaire
(Garnefski & Kraaij, 2006).
Results. Although most nurses do not experience
depression, anxiety, and stress beyond the normal
level, there is a non-negligible proportion who exhibit
symptoms ranging from mild to extremely severe
levels of these negative emotional states.
The largest proportion of severe and extremely severe
results, that might be of clinical significance, was observed for anxiety (18.53%). The maladaptive
strategy of blaming others was found to be a
significant predictor of depression, anxiety, stress
and positive refocusing was significant predictor of
stress.
Conclusion. The results suggest that the use of specific
cognitive emotion regulation strategies plays an
important role in nurses’ mental health, measured as
rates of depression, anxiety and stress. This underscores
the need for and importance of implementing
education and training programmes on cognitive
emotion regulation strategies in the professional
education of nurses
Zagreb i poplave: 60. obljetnica velike poplave
No full textU listopadu 2024. godine obilježena je 60. obljetnica povijesne poplave rijeke Save iz 1964. godine, najveće zabilježene poplave u povijesti Zagreba, koja je prouzročila velike materijalne štete i ljudske žrtve. Ovaj katastrofalni događaj bio je ključan poticaj za razvoj sustava obrane od poplava, što je uključivalo izgradnju nasipa, preljeva Jankomir i kanala Sava-Odra. Istovremeno je započela regulacija korita i gradnja retencijskih brana na medvedničkim potocima, koji su kroz povijest često uzrokovali poplave na zagrebačkom području. Iako je sustav značajno smanjio rizik od velikih poplava Save, recentni ekstremni vremenski uvjeti i još uvijek prisutne bujične poplave naglašavaju potrebu za daljnjim unaprjeđenjem infrastrukture i prilagodbom obrambenih mjera. Budući da su tekućice dinamični sustavi podložni promjenama, kontinuirana istraživanja i prilagodba strategija ključni su za dugoročnu zaštitu Zagreba od budućih poplavnih prijetnji

Manipulation and Goal Setting Motivation: An Unexamined Ethical Relationship
Get PDFManipulation is well–studied in psychology and philosophy, and there is substantial
literature on organizational motivational theories. Yet, a thorough examination
of whether organizational motivational practices are manipulative is lacking.
This paper defines manipulation and applies the definition to Goal Setting
Theory. It addresses two questions: is Goal Setting Motivation manipulation and
is it wrong? We also explore how non–manipulative ideal motivational practices
could be altered to become manipulative

Get PDFOptimization of the Transmission Tube of a Ball Mill Based on the EDEM-Workbench Method
Get PDFThe structural design of the transmission tube significantly influences its mechanical behaviour under operating conditions, making structural optimization crucial for improving the performance and reliability of a ball mill. In this paper, the response surface method and multi-objective genetic algorithm are used to carry out optimization research on the existing BM4213 ball mill transmission tube structure to address the problem of its large size and size-related material costs. Firstly, the discrete element simulation of a transmission tube based on the Altair EDEM software is carried out to analyse the movement of the material in the transmission tube and determine the load acting on it. Thereafter, the load exerted on the transmission tube by the material is imported into the static analysis module in Workbench to obtain the stress and deformation of the transmission tube at full load start-up using the coupled EDEM-Workbench method. Subsequently, the part of the design to be optimized is determined based on the results of the static analysis. Finally, a mathematical model of the transmission tube optimization design is constructed; using the response surface optimization module in Workbench and a multi-objective genetic algorithm, a comprehensive optimization design of the transmission tube is carried out. The structural dimensions in the mathematical model of the transmission tube are adjusted to effectively reduce its stress and mass. The optimized transmission tube exhibited reductions of 6.735% in mass, 9.188% in maximum stress, and 16.721% in maximum deformation. This research provides an essential reference for the optimized design of the BM4213 ball mill transmission tube

Machiavelli’s New Prince Caught in Drag
No full textThis article offers a critical reconsideration of the gendered relation between virtù and fortune in Machiavelli’s principal political texts. In the current feminist studies on Machiavelli, this relation is perceived in either antagonistic or mimetic terms. In dialogue with both strands of feminist readings and with special attention to Pitkin’s interpretation of Machiavelli, this paper seeks to bridge the democratic and feminist face(s) of Machiavelli. From a feminist and gender-dissidence perspective, it then provides an alternative view of the new prince as a man in drag and examines his role in the regulation of social conflict
