A NÁCI ÁBRÁZOLÁSOK EMBERESZMÉNYE, IFJÚKÉPE ÉS GYERMEKREPREZENTÁCIÓS GYAKORLATA
Authors: TÁMBA Renátó
Published: December 2024

Dolgozatomban a náci képi és plasztikai ábrázolás embereszményét, ifjú- és gyermekképét kívánom vizsgálni a korszak ideológiai eredetű produktumain keresztül, az ikonográfiai- ikonológiai módszer segítségével. E korszak megjelenítésein direkt módon tükröződtek a náci ideológia szólamai, az egészséges, erős, árja férfi eszménye és az áldozatkész, családjáért odaadó nő képe, melyek propagandisztikus jelleggel jelentek meg a festményeken és a szobrokon, meglehetősen diszkriminatív, túlzóan esszencialista módon viszonyulva az emberlét alapkérdéseihez. A gyermek leginkább családi környezetben jelent meg vagy a Hitlerjugend tagjaként, korántsem önértékénél fogva; a formálódó, érő gyermek jelenvalósága nem foglalkoztatta a korszak propagandisztikus vizuális kultúráját, amely miután jövőorientált volt, a náci eszme célkitűzéseit, ideáljait, eszmei elvárásait vetítette a gyermek-, család- és ifjú- ábrázolásokra egyaránt. Írásomban azt vizsgálom, hogy milyen jellegzetes módokon érvényesültek az új eszmények a náci éra ideológiailag kártékony vizuális kultúrájában. A náci ábrázolás problematikus jellegénél fogva érdemes koncentrálni az ideológiailag kártékony vizuális kultúra destruktív hatásaira is.

Authors: Ramírez Brahiam , Estrella Soledad
Published: December 2024

This article presents the results of a survey that evaluated the perception of the effectiveness of the Lesson Study (LS) process in nine future mathematics teachers (FMT), who, organized in LS groups, planned lessons and elaborated final reports, worked into a LS model for the undergraduate training of future teachers. From a qualitative and interpretative analysis, the survey responses are analyzed with reflections on the teaching practice of LS research, and with the perceptions of two FPM who opted for this methodology in their Final Project. The results reveal that, after teaching practices based on LS, the FMT presents a high perception of the effectiveness of LS, even increasing in those who were followed up.
Evaluating ChatGPT’s efficacy in addressing common patient questions in plastic surgery consultations
Authors: Brochu Baylee M , Mirsky Nicholas A , Thaller Seth R
Published: December 2024

Aim: This study aims to investigate the ability of ChatGPT to answer common patient questions related to the five most common aesthetic procedures.

Methods: We asked three questions, two of which were the same across procedures, for each of the five most common plastic surgery procedures as determined by the 2022 American Society of Plastic Surgery (ASPS) Procedural Statistics Release. These were posed to ChatGPT on the same day, using the same account. Then, they were compared to the corresponding information on the ASPS website.

Results: We found that ChatGPT provides accurate, organized, and grammatically correct responses to common patient questions. It was comparable to the ASPS website in terms of comprehensiveness of the complications listed across procedures. However, its responses regarding recovery time were less detailed than the corresponding ASPS articles. It included accurate information on recovery time that was unavailable on the ASPS site. For procedure-specific questions, ChatGPT was more detailed 2/5 times, less detailed 1/5 times, and provided a completely different answer than the ASPS website 2/5 times.

Conclusion: This study provides support for ChatGPT’s utilization as a tool to improve the efficiency of consultations for aesthetic procedures. However, it is important to recognize ChatGPT’s limitations in answering questions in a patient/procedure-specific way. Therefore, it is not a substitute for an experienced surgeon consultation. Further research is needed to assess the reliability of ChatGPT before it can be fully recommended as an ultimate patient learning tool.
A Proof of the Riemann Hypothesis Based on a New Expression of the Completed Zeta Function
Authors: Zhang Weicun
Published: December 2024

The Riemann Hypothesis (RH) is proved based on a new expression of the completed zeta function ξ(s), which was obtained through paring the conjugate zeros ρi and ρ ¯ i in the Hadamard product, with consideration of the multiplicities of zeros, i.e. ξ ( s ) = ξ ( 0 ) ∏ ρ ( 1 − s ρ ) = ξ ( 0 ) ∏ i = 1 ∞ ( 1 − s ρ i ) ( 1 − s ρ ¯ i ) = ξ ( 0 ) ∏ i = 1 ∞ ( β i 2 α i 2 + β i 2 + ( s − α i ) 2 α i 2 + β i 2 ) m i where ξ ( 0 ) = 1 2 , ρ i = α i + j β i and ρ ¯ i = α i − j β i are the complex conjugate zeros of ξ(s), 0 < αi < 1 and βi ≠ 0 are real numbers, mi ≥ 1 is the multiplicity of ρi, finite and unique (see Lemma 9 and Lemma 10), 0 < |β1 | ≤ |β2| ≤ ⋯. Then, according to the functional equation ξ(s) = ξ(1 − s), we have ∏ i = 1 ∞ ( 1 + ( s − α i ) 2 β i 2 ) m i = ∏ i = 1 ∞ ( 1 + ( 1 − s − α i ) 2 β i 2 ) m i Owing to the divisibility of the infinite product of polynomial factors and the uniqueness of mi , the above equation is equivalent to (see Lemma 3 for details) ( 1 + ( s − α i ) 2 β i 2 ) m i = ( 1 + ( 1 − s − α i ) 2 β i 2 ) m i , i = 1 , 2 , 3 , … , ∞ which is further equivalent to α i = 1 2 , 0 < | β 1 | < | β 2 | < | β 3 | < ⋯ , i = 1 , 2 , 3 , … , ∞ Thus we conclude that the RH is true.

Application of Deep Learning to Identify Flutter Flight Testing Signals Parameters and Analysis of Real F-18 Flutter Flight Test Data
Authors: Abou-Kebeh LLano Sami , Gil-Pita Roberto , Rosa-Zurera Manuel
Published: December 2024

Aircraft envelope expansion during the installation of new underwing stores presents significant challenges, particularly due to the aeroelastic flutter phenomenon. Accurate modeling of aeroelastic behavior often necessitates flight testing, which poses risks due to the potential catastrophic consequences of reaching the flutter point. Traditional methods, like frequency sweeps, are effective but require prolonged exposure to flutter conditions, making them less suitable for transonic flight validations. This paper introduces a robust deep learning approach to process sine-dwell signals from aeroelastic Flutter Flight Tests, characterized by short data lengths (less than 5 seconds) and low frequencies (less than 10 Hz). We explore the preliminary viability of different deep learning networks and compare their performance to existing methods such as the PRESTO algorithm and Laplace Wavelet estimation. Deep learning algorithms demonstrate substantial accuracy and robustness, providing reliable parameter identification for flutter analysis while significantly reducing the time spent near flutter conditions. Although the results with the networks trained show less accuracy than the PRESTO algorithm but more than the Laplace Wavelet estimation, the results are promising enough to justify extended investigation on this area. This approach is validated using both synthetic data and real F-18 flight test signals, highlighting its potential for real-time analysis and broader applicability in aeroelastic testing.

Authors: Orlof Wiktor , Sołowiej-Chmiel Justyna , Waszkiewicz Napoleon
Published: December 2024

Introduction: Dissociative identity disorder (DID) is a condition characterized by the presence of at least two distinct identities. Each identity has unique patterns of perception, of making interactions, of thinking about oneself and one's surroundings. The experience of severe trauma, particularly in childhood, is considered the most common etiological source. Diagnosis of DID is difficult, requiring observation and understanding of complex mechanisms. In this paper, the authors used a holistic approach to the psychiatric and psychological diagnosis process. Case Presentation: A 33-year-old woman presented to the Department of Psychiatry, Medical University of Bialystok, due to frequent amnestic states accompanied by a lack of continuity of autobiographical memory. The patient had previously been treated at the Mental Health Outpatient Clinic with suspected schizophrenia. The patient's history was difficult to collect and switches between identities were observed, with a marked change in behavior. The stories she reported changed, depending on the dominant identity, each of which varied in terms of gender, name, sexual orientation, interests or pattern of behavior. Outcome: The patient underwent a thorough laboratory diagnosis, including toxicologic diagnosis, neuroimaging and psychological diagnosis. On the basis of the information collected, based on the ICD-10 Classification, the diagnosis was: F44.8 - dissociative identity disorder. Discussion: The clinical entity described by the authors still poses many diagnostic and therapeutic uncertainties. In the literature, we do not find a case description that holistically encompasses DID. Therefore, the following description represents a unique bibliographic item, useful to professionals in planning medical and therapeutic care.

The Unstable Lagrangian: Dynamics of Reality
Authors: Patra Rohit
Published: December 2024

This paper presents a novel hypothesis for understanding the dynamics of energy redistribution in systems characterized by pressure fluctuations and quantum uncertainty. The proposed model investigates the behavior of energy concentration within a system, conceptualized as a set of “cosmic nodes,” where energy peaks are continuously fluctuating due to pressure-driven dynamics and quantum effects. The system is described by a modified Euler-Lagrange equation, which governs the evolution of the energy field without stable equilibrium, instead exhibiting continuous fluctuations in energy concentration. We introduce a re-interpretation of mass in the model, where it is not a traditional mass parameter, but a term that encapsulates the effects of pressure and energy redistribution. The solutions to the derived equation describe oscillatory modes and fluctuating energy fields, governed by pressure variations and the inherent randomness of quantum fluctuations. This approach provides a fresh perspective on the stability of energy fields, suggesting that the system constantly evolves through energy redistribution driven by pressure, with no final stable state. The implications of these findings extend to understanding complex systems in physics, where pressure and fluctuations play a crucial role in the behavior of energy at fundamental scales.
Critical Failures in Aviation Components: The Role of Hydrogen Embrittlement
Authors: Karaveli Kadir Kaan , Kalaycıoğlu Mete , Bal Burak , Saracyakupoglu Tamer
Published: December 2024

Hydrogen embrittlement (HE) poses a critical safety risk in the aviation industry, causing unexpected failures in high-strength metals and alloys used in essential components. This study focuses on detailed analyses of multiple aviation incidents and accidents where HE played a significant role, particularly concerning failures in helicopter drive systems and fixed-wing aircraft crankshaft bolts. Investigations revealed that these failures were primarily caused by hydrogen introduced during manufacturing processes, such as electroplating and surface treatments, which were insufficiently mitigated by post-processing techniques like dehydrogenation. These incidents led to Airworthiness Directives (ADs), which mandated corrective actions to prevent similar occurrences, such as improved manufacturing protocols and enhanced material testing. By presenting concrete evidence from metallurgical analyses and documented aviation failures, this paper highlights the critical need for robust manufacturing controls, stringent post-treatment procedures, and continuous monitoring to address hydrogen embrittlement risks effectively and enhance aviation safety.

Authors: Sigit Sigit Dicky Mardianto , Untari N Dewi Handayani
Published: December 2024

ABSTRACT
Computer components are devices that are currently indispensable for almost all human needs. In its development, computer components have had a significant increase in data processing capabilities, which sometimes makes the period of use of computer components that comply with minimum specifications shorter. How could it not be, when a new computer component is launched by the company that makes it, then within one to two years the company that makes it has launched a new computer component product with higher specifications and higher efficiency. This can also cause an increase in electronic waste due to computer components that can no longer meet needs. Then, in terms of the software used, there was also a significant increase, forcing component users to replace the computer components used with computer components that have specifications that match the needs of the software used. Thus, I feel the need to help computer component users so that they can determine a good combination of computer components, so that they can achieve the computer component requirements required by the software used.

Gender differences in cyberbullying perpetration on Facebook: the role of empathy, callous unemotional traits, and moral disengagement
Authors: Baltzidis Eleftherios
Published: December 2024

Despite extensive research on cyberbullying, the interplay between gender, personality factors, and cyberbullying perpetration behaviours on social networking sites remains underexplored, particularly among young adults. This study aims to examine gender differences in cyberbullying perpetration on Facebook and, guided by the General Aggression Model as the theoretical framework, to explain how individual factors such as empathy, callous-unemotional traits, and moral disengagement, as moderated by the number of Facebook friends, contribute to cyberbullying perpetration on Facebook. This study investigates this complex association among a community sample of 171 participants aged 18 to 35 years (57.9% female), selected through convenience sampling and the snowball recruitment method. The findings revealed no significant interaction effects of the number of Facebook friends in the association between personality factors and cyberbullying perpetration on Facebook. More, results showed no significant gender differences in the frequency of cyberbullying perpetration. However, distinct gender patterns emerged in the association between personality traits and cyberbullying perpetration on Facebook. Males demonstrated stronger associations between moral disengagement, cognitive empathy, and cyberbullying perpetration on Facebook, while females exhibited significant associations between cognitive and affective empathy and cyberbullying perpetration on Facebook. The implications of these findings are thoroughly discussed in relation to existing literature.

Sepsis-associated acute kidney injury (SA-AKI) portends severe health burden due to significant morbidity and mortality, while early diagnosis remains challenging. In this study, proximity-dependent barcoding assay (PBA) was established to profile the surface proteome of single urinary extracellular vesicle (uEV). Principle uEV clusters with unique function and origination were profiled in SA-AKI. Reduction of complement receptor CD35 on single uEV (CD35-uEV) was revealed as a novel biomarker from one of the main EV clusters with significant proportional differences. CD35-uEV demonstrated high diagnostic accuracy for SA-AKI (receiver operating characteristic-area under the curve (ROC-AUC), 0.98 in screening cohort (n=16), and 0.89 in validation cohort (n=134)). Besides, CD35-uEV enables identification of subclinical AKI (ROC-AUC, 0.84 in prospective cohort (n=72)) which was independent of other clinical parameters as validated by multivariate analysis (p<0.001). Moreover, CD35-uEV correlated closely with AKI severity which also predicts persistent AKI (ROC-AUC, 0.77), progression to AKD (ROC-AUC, 0.66), and mortality risks (ROC-AUC, 0.70). Integrative single-cell and spatial transcriptomics analysis identified that CD35-uEV originated from injured podocyte characterized with diminished CD35 expression. The combination of CD35-uEV with tubular injury biomarkers (TIMP2*IGFBP7) showed improved accuracy in identifying subclinical SA-AKI and prediction of severe stages. Overall, this study identified a novel biomarker on single uEV related to injured podocyte for early diagnosis and risk stratification of SA-AKI.

Published: December 2024

Elucidating the characteristics of desorption and diffusion of coal seam gas is essential for the prevention of gas disasters in coal mines. In this study, constant-temperature gas dispersion tests were conducted on lignite, fiery coal, and anthracite to unveil the intricate dynamics of gas diffusion in coal samples under the influence of coal metamorphism. The primary focus was to determine their gas desorption and diffusion characteristics and analyze the mathematical expressions of gas dispersion for coal samples with varying levels of metamorphism during different periods. The findings revealed that coal samples with high metamorphism could attain the desorption limit relatively swiftly, while low-rank lignite required a longer duration to reach the limit. Notably, the gas desorption diffusion rate exhibited significant sensitivity to the coal's metamorphism level. The gas desorption rate within the first 10 minutes was observed to be stable for lignite and fiery coal, while anthracite displayed a faster desorption rate in the initial 4 minutes followed by stability in the subsequent 6 minutes. Furthermore, the effective gas diffusion coefficient demonstrated a robust negative linear correlation with the degree of metamorphism, signifying a decrease in gas diffusion ability with an increase in metamorphism level. Empirical formulas employed to fit anthracite yielded relatively stable correlation indices, with Formula 3 deemed more suitable for depicting the gas desorption processes of lignite and fiery coal.
Polysaccharide from Ganoderma sinense improves cognitive capacity in a mouse model of Alzheimer’s disease via reshaping the gut microbiota and short-chain fatty acid metabolism

Published: December 2024

Two types of polysaccharides from Ganoderma sinense termed GSP1 (Mw: 58.92 kDa, consisting of fourteen monosaccharides) and GSP2 (Mw: 3.27 kDa, consisting of fourteen monosaccharides) were purified, and their protective effects against Alzheimer's disease (AD) in a mouse model were investigated. An in vitro study suggested that GSPs protect SH-SY5Y cells from neurotoxicity and oxidative stress in response to glutamate. The effect of GSP1 on the cognitive and memory capacity of the AD mouse model was confirmed using the Morris Water Maze, Object Recognition, and Nestlet Shredding tests. Additionally, treatment with GSP1 could reduce the amyloid β plaques in the brains of AD mice. Multi-omics analysis of the gut microbiome, short-chain fatty acid (SCFAs) metabolomics, and behavioral tests were conducted to elucidate the therapeutic mechanisms of GSPs. The results revealed that GSP1 improved the diversity of the microbiome, restored the structure of the gut microflora, and regulated SCFA metabolism. Four genera (Turicibacter, Jeotgalicoccus, Staphylococcusa, and Odoribacter) were significantly associated with both behavioral tests and SCFAs metabolism in the GSP1-treated group. These findings provide a basis for the development of polysaccharide drugs against AD and for further development of GSP1.

Published: December 2024

Background
There are differences in the rates of short stature (WHO height-z score < -2SD) between the various sectors in Israeli children aged 6–7 years, with higher rates in the ultraorthodox Jewish population. We aimed to: (a) Compare the anthropometric data at 0–2 years of age and the obstetric and demographic data of children with short stature at 6–7 years of age with those of children with normal height. (b) Assess risk factors for short stature at the age of 6–7 years. (c) Evaluate the impact of clinical and socioeconomic factors on linear growth from birth to the age of 6–7 years.
Methods
This was a retrospective cohort study. Anonymized anthropometric data measured at the first grade of school during 2015–2019 were collected from the Ministry of Health records. The participants were stratified into sectors according to the affiliation of their school. Retrospective growth and sociodemographic data were extracted for each child from the national birth registry and Maternal Child Health Clinics files.
Results
The cohort included 368,088 children, with a median age of 6.7 years (IQR 6.3,7.0). Short stature was more prevalent in ultraorthodox Jewish boys (3.8%) and girls (3.2%), and least prevalent in Arab boys (0.8%) and girls (0.7%) compared with all other sectors (P < 0.001). The rate of stunting in Bedouin children was similar to that in the general population (1.6%). In a logistic regression model, the variables that predicted short stature at the age of 6–7 years were female sex, longer gestation, lower height-z score at 2 months of age, birth weight < 90th percentile, being in the ultraorthodox Jewish sector, and a smaller change in height-z score until 2 years of age.
Conclusions
Growth gaps between different sectors of school-aged Israeli children emerge during the first 2 years of life. The most vulnerable population for stunting is the ultraorthodox population. Public health services, including MCH clinics and primary caregivers, should prioritize this group and closely monitor for growth faltering during the first and second years of life.
The cardiovascular benefits of dark chocolate supplementation during high-intensity resistance exercise in the early follicular and mid-luteal phases of the menstrual cycle
Authors: Wang Chun Wei , Fang Shih-Hua , Yu Tse-An , Chen Liang-You , Wang Chung-Kai , Wang Soun-Cheng , He Cheng-Shiun
Published: December 2024

Background:
Dark chocolate, rich in flavanols, may support vascular health by reducing arterial stiffness and blood pressure across menstrual phases. This study examined the effects of 85% dark chocolate on nitric oxide (NO) levels and vascular function during high-intensity resistance exercise in healthy women across the early follicular and mid-luteal phases.
Methods:
Thirty-one healthy women (aged 20–30 years) with regular menstrual cycles completed a randomized, crossover study. Participants consumed either 85% dark chocolate or milk chocolate (1g/kg body weight) before high-intensity resistance exercise during the early follicular (days 2–5) and mid-luteal (days 18–24) phases of two menstrual cycles. Finger-toe pulse wave velocity (ftPWV), arterial stiffness, blood pressure, and plasma NO levels were measured at rest, 2 hours after chocolate consumption (baseline), immediately post-exercise (T0), and at 60 (T60) and 120 (T120) minutes post-exercise.
Results:
Dark chocolate supplementation significantly increased NO levels and reduced systolic blood pressure (SBP), ftPWV, and arterial pressure volume index (API) (p < 0.05) compared to milk chocolate across both menstrual phases. During the early follicular phase, dark chocolate also attenuated exercise-induced increases in arterial stiffness and blood pressure (p < 0.05).
Conclusion:
85% dark chocolate supplementation may reduce the negative vascular effects of high-intensity resistance exercise, particularly by lowering blood pressure, arterial stiffness, and API, especially in the early follicular phase. These findings suggest that dark chocolate could be a practical, non-pharmacological intervention for improving cardiovascular health in women.
Lateral Force Transfer Mechanism of Staggered Truss Structures Influenced by Floor Slab Stiffness
Authors: Wang Yumei , Yu Kejie
Published: December 2024

Staggered truss structures are gaining more attentions due to their double-span spaces and adaptability in the industrialized age. However, the role of floors on the force transfer still needs more parameter analysis. This paper used three structural units to study the floor actions: the first case focuses on the shear distribution among different trusses on floors with full rigidity, full-flexibility, openings and diaphragm constraints; the second case focuses on the shear distribution among truss members with different joint restrictions; the third case focuses on the plastic hinge development and failure mode for floors with different stiffness reduction factors. Results showed that, rigid floors with diaphragm constraints coordinate different plane trusses well, but put large demands in the open corridor sections; while flexible floors are unfavorable to non-truss columns; all-fixed-joint model causes large shear and bending in all truss members; all-hinged-joint model softens the whole structure and induces large shear in the 1st story; fixing the chords’ joints could decrease the member forces and improve the overall structural performance. Effective lateral force transfer measures, either continuous chords or appropriate rigidity of floors, are key to ensure the seismic performance and favorable failure modes of staggered truss structures.

Published: December 2024

Background Early identification of Schizophrenia Spectrum Disorder (SSD) is crucial for effective intervention and prognosis improvement. Previous neuroimaging-based classifications have primarily focused on chronic, medicated SSD cohorts. However, the question remains whether brain metrics identified in these populations can serve as trait biomarkers for early-stage SSD. This study investigates whether brain metrics identified in chronic, medicated SSD can function as trait biomarkers for early-stage SSD.Methods Data were collected from 502 SSD patients and 575 healthy controls (HCs) across four medical institutions. Resting-state functional connectivity (FC) features were used to train a Support Vector Machine (SVM) classifier on individuals with medicated chronic SSD and HCs from three sites. The remaining site, comprising both chronic medicated and first-episode unmedicated SSD patients, was used for independent validation. A univariable analysis examined the association between medication dosage or illness duration and FC.Results The classifier achieved 69% accuracy (P = 2.86e-13), 63% sensitivity, and 75% specificity when tested on an independent dataset. Subgroup analysis showed 71% sensitivity (P = 4.63e-05) for chronic medicated SSD, but poor generalization to first-episode unmedicated SSD (sensitivity = 48%, P = 0.68). Univariable analysis revealed a significant association between FC and medication usage, but not disease duration.Conclusions Classifiers developed on chronic medicated SSD may predominantly capture state features of chronicity and medication, overshadowing potential SSD traits. This partially explains the current classifiers' non-generalizability across SSD patients with different clinical states, underscoring the need for models that can enhance the early detection of schizophrenia neural pathology.

Published: December 2024

Background
Work-related musculoskeletal disorders (WMSDs) significantly affect bus drivers’ health and warrant adequate attention. This study aimed to explore the associations of occupational stress with WMSDs among bus drivers, and assess the potential mediating role of sleep quality and nighttime sleep duration.
Methods
A total of 1792 bus drivers with the available information from 5 subsidiaries of Shenzhen Bus Group by convenient sampling method were included. Logistic regression model was used to estimate the associations of occupational stress, sleep quality and nighttime sleep duration with WMSDs. Mediation analysis was performed to explore the role of sleep quality and nighttime sleep duration in the association between occupational stress and WMSDs.
Results
The prevalence rate of single-site, multiple-site, and overall WMSDs among bus drivers were 10.04%, 59.26%, and 69.31%, respectively. Compared to participants without occupational stress, those with occupational stress showed a 92% higher risk of multiple-site WMSDs and a 1.03-fold elevated risk of overall WMSDs [OR (95% confidence interval, CI) = 1.92 (1.56, 2.36) and 2.03 (1.63, 2.55), respectively]. Bus drivers with poor sleep quality had a 3.73-fold risk of multiple-site WMSDs and 4.82-fold risk of overall WMSDs than those in high sleep quality [OR (95% CI) = 3.73 (2.89, 4.84) and 4.82 (3.53, 6.71), respectively]. Each 1-hour increment in nighttime sleep duration was linked to a 36% declined risk of multiple-site WMSDs and a 37% reduced risk of overall WMSDs [OR (95% CI) = 0.64 (0.58, 0.71) and 0.63 (0.57, 0.70), respectively]. Further mediation analysis indicated that poor sleep quality and decreased nighttime sleep duration partly mediate the associations between occupational stress and risk of both multiple-site and overall WMSDs.
Conclusion
Occupational stress and poor sleep quality significantly elevated the risk of both multiple-site and overall WMSDs, while increased nighttime sleep duration was associated with a reduced risk of multiple-site and overall WMSDs. Sleep quality and nighttime sleep duration could partly mediate the relationship between occupational stress and both multiple-site and overall WMSDs. Highlighting the importance of reducing occupational stress, maintaining good sleep quality and sufficient nighttime sleep duration for WMSDs prevention.

Published: December 2024

Background: Single superior symphyseal plating is the most effective method for managing vertically unstable Tile C1-2 and C1-3 pelvic ring injuries.However, high rates of implant failure were more frequently observed in obese patients (body mass index< 30). The study aimed to determine the potential reduction in implant failure rates by adding an anterior symphyseal plate in obese patients (class I).
Methods: The study was designed as a prospective, randomized controlled trial with a single-blind methodology, conducted at a level 1 trauma center.The study involved 36 patients with Tile C1-2 and C1-3 injuries, and class I obesity between February 2022 and May 2023. All cases had posterior and anterior ring fixation, with 18 cases having superior symphyseal plating and 18 cases having additional anterior plating (Groups A and B). The primary outcomes were radiological, functional outcomes, and implant failure rates.
Results: Patients in group A were followed up for an average of 13.39 months, and those in group B for 13.7 months. Group A exhibited a significantly shorter operative time with a mean difference of 30 minutes (p < 0.001), as well as lower reoperation rates (p = 0.03). Both groups had similar final clinical and radiological outcomes (p = 0.44 and 0.78) and implant failure rates (p = 0.18) at the last follow-up.
Conclusion: The authors found that using a single high-quality symphyseal plate effectively addresses symphyseal diastasis in vertically unstable Tile C1-2 and C1-3 pelvic ring injuries among patients with class I obesity. This method lowers morbidity by reducing operation times and minimizing reoperation rates, while the inclusion of an additional anterior plate does not enhance the final radiological and clinical outcomes.
Level of Evidence: Therapeutic Level I study.

The global ICU patient survival rate has increased dramatically due to advancements in critical care practices and technology; yet, post-ICU survivors frequently struggle with post-ICU syndrome (PICS), significantly affecting their overall health and well-being (Needham et al., 2012). The lack of structured post-ICU care in Saudi Arabia, coupled with a growing aging population and the ambitious Saudi Vision 2030, highlights the urgency of establishing innovative healthcare solutions.
This protocol introduces a multidisciplinary virtual (tele) post-ICU follow-up clinic designed to address the unmet needs of ICU survivors. The clinic employs advancements in telemedicine, digital health, and multidisciplinary care to deliver comprehensive, accessible, and cost-effective support. Objectives include improving survivors' quality of life, reducing healthcare utilization, and enhancing care equity. Quantitative and qualitative methods will assess outcomes such as quality of life, cognitive and psychological recovery, and healthcare cost savings. This initiative not only addresses a critical gap in the healthcare system but also aligns with national goals to improve health outcomes and life expectancy.

Mobbing ist in aller Munde – gerade ‚Cybermobbing’ scheint aktuell ein regelrechtes Massenphänomen zu sein. Und doch ist Mobbing keineswegs neu, vielmehr bringen neue Formen ein neues Bewusstsein hervor. Die Autoren des Buches beleuchten die Thematik in den neun Kapiteln ihres Ratgebers nicht nur theoretisch, sondern auch praktisch. Das erste Kapitel bietet eine allgemeine Einführung in die Thematik Mobbing in Schule, Ausbildung, Arbeitswelt und Internet. Mit Hilfe von Definitionen, Abgrenzungen zu den Begriffen ‚Alltagskonflikt’ und ‚Stalking’ sowie statistischen Daten, Mobbingverläufen und -ursachen sollen die Leserinnen und Leser in die Thematik eingeführt werden.
In den folgenden Kapiteln werden Funktionen undVerarbeitungsstrategien des Gehirns sowie Definition, Wirkungen und Äußerungen von Stress näher beleuchtet. Aber auch die Frage nach Zivilcourage, Selbstbewusstseinsstärkung und den schwerwiegenden Folgen von Mobbing werden in den Mittelpunkt des Diskurses gerückt. Schließlich werden die Suche nach Opfern und Tätern sowie allgemeine Gründe für Mobbing beleuchtet.Obwohl der Hauptblickpunkt des Buches der Arbeitsplatz mit seinen Herausforderungen bleibt, werden auch Ursachen für Mobbing im Internet und in der Schule gegen Kinder und Lehrerinnen und Lehrer gesucht. Gerade die Schule ist der Ort, an dem Fähigkeiten zur Frustrations- und Konfliktbewältigung gelernt und Toleranz und Respekt gelebt werden sollen. Die Frage, welchen Einfluss Familie und Peers hierbei besitzen, bleibt jedoch weitgehend ungeklärt. Bei der Betrachtung von Cybermobbing werden zu Beginn allgemeine Begriffserklärungen in gängigem Fachjargon angeboten.
Die Artikel sind wissenschaftlich, aber gleichzeitig übersichtlich, anschaulich, verständlich und strukturiert geschrieben und beziehen sich aufeinander. So werden eine Vielzahl an Hilfsangeboten in ihrer Funktion und Wirkung genauer beschrieben. Internetlinks sollen Eltern, pädagogischen Fachkräften oder Betroffenen konkrete Hilfen anbieten, gleichzeitig sollen sie über mögliche Gefahren des Web 2.0 informiert werden um sich präventiv vor Mobbing schützen zu können. Abschließend der Appell der Autoren: Auch im Zeitalter von E-Mail und SMS sollte man nicht übereinander, sondern miteinander reden!

Kampagnen erreichen uns in unserem alltäglichen Leben auf unterschiedlichsten Wegen, über das Fernsehen, das Radio, auf Plakatwänden oder im Internet. Das Modellprojekt KAJUTO befasst sich mit KAmpagnen von JUgendlichen für TOleranz und verfolgt dabei zwei Ziele: Toleranzbereitschaft allgemein und Medienkompetenz der partizipierenden Jugendlichen sollen gefördert werden. Die kritische Auseinandersetzung mit Andersartigkeit und Vorurteilen soll nicht nur auf einer reflexiv-theoretischen, sondern auch auf einer aktiv-kreativen Ebene stattfinden, indem Jugendliche alle Produktionsschritte einer Kampagne selber durchlaufen und so zu einem fertigen Endprodukt gelangen.
Die im Rahmen des Projekts erschienene Publikation Kampagnen selbstgemacht versteht sich als Anleitung für eben solche Kampagnenprojekte. Das Autorenteam bezieht sich auf eigene Erfahrungen in der Arbeit mit Jugendlichen. Der zunächst theoretischen Herangehensweise folgt eine Beleuchtung der Kampagnenarbeit aus Sicht der Medienkompetenzförderung. Anschließend wird modellhaft der Projektablauf geschildert, bevor mehrere Vorschläge für verschiedene Kampagnenarten detailliert dargestellt werden. Vorgeschlagen werden Kampagnen, die sich mit Videoclips, Fotoaktionen oder Audiobeiträgen befassen. Kampagnen selbstgemacht dient damit als Grundlage, Ideenanstoß und Leitfaden für all diejenigen, die eine aktive und praktische Herangehensweise zur Förderung der Medienkompetenz anstreben.
Distributed Digital Leadership?

Published: December 2024

Im Zuge der wissenschaftlichen Auseinandersetzung mit digitalen Transformationsprozessen (in) der Schule rücken zunehmend auch Führungstheorien und deren Implikationen in den Fokus. Dabei scheinen Ansätze einer «Distributed Leadership» und «Technology Leadership» resp. «Digital Leadership» nicht nur besonders präsent, auch lassen sich in bisherigen Arbeiten Verweise auf Kombinationen dieser Konzepte finden. Trotz der gemeinsamen Erwähnung resp. Kombination dieser Ansätze mangelt es an einer systematischen Betrachtung, die die benannten Führungskonzepte in Bezug zueinander setzt. Das vorliegende Papier adressiert dieses Desiderat und geht mithilfe der Aufbereitung deutschsprachiger und internationaler Diskurse der Frage nach, was genau unter «Distributed Digital Leadership» verstanden werden kann. Dabei wird die Beziehung zwischen den genannten Führungskonzepten kritisch beleuchtet und existierende Gemeinsamkeiten und Unterschiede werden herausgestellt. Dies dient als Grundlage einer kritischen Diskussion des in der Literatur häufig als «neu» artikulierten Konzepts einer «Distributed Digital Leadership». Die Erkenntnisse zeigen deutlich, dass Führung im Kontext von Digitalisierung Formen von Distributed Leadership ermöglicht und erfordert; eine Verbindung resp. Integration beider Konzepte liegt daher nahe. Gleichwohl handelt es sich hierbei um keine «neue» Erkenntnis, wie wir anhand der benannten Diskurse aufzeigen werden.
