Understanding public awareness of fall epidemiology in the United States: A national cross-sectional study
Authors: Sheridan Elizabeth , Wiseman Jessica M. , Quatman Carmen E.
Published: February 2025

Background and objectives

Falls are a leading cause of death and disability for adults aged 65 and older, despite the availability of evidence-based interventions to decrease fall risk. We sought to assess public awareness of falls in the United States (US), including when falls are most likely to occur.

Methods

An online survey was distributed to US adults aged 18 or older.

Results

A total of 1,069 individuals agreed to be contacted for the study, and 966 (90.4%) of them participated in the study. The largest proportion of participants believed that falls are most likely to occur at night (41.2%). Most of the participants correctly identified falls as preventable (97.9%) and recognized homes as the primary location (94.8%). Participants understood the increased risk of subsequent falls after a single fall (97.4%) and the low rate of informing doctors after a fall (82.9%). However, many were unaware that falls are not a normal part of aging (58.8%), one in four older adults fall annually (58.0%), most falls do not cause injury (60.8%), or that $50 billion is the annual cost of falls (96.3%).

Conclusions

This study reveals gaps in public awareness of fall epidemiology and severity among older adults. Contrary to common belief, falls occur predominantly during morning and afternoon hours, not in the evening or at night. While most respondents correctly identified falls as preventable, many erroneously considered them an inevitable consequence of aging. Additionally, the actual medical costs of falls far exceed public estimates. These findings underscore the need for targeted public health interventions to address misconceptions and enhance the awareness of fall risks and prevention strategies.

Authors: Kilsbach Sebastian , Rezat Sara , Michel Nadine , Karabey Rabia , Stahl Maja , Wachsmuth Henning
Published: February 2025

This article presents a multi-level annotation approach for argumentative learner texts that was developed as part of an interdisciplinary DFG project. The project aims at the automated generation of individualized, development-promoting and learner-sensitive feedback on argumentative student texts and is situated in the field of AI-supported text production. To generate automated feedback, the first step was to manually annotate an extensive text corpus consisting of 1,320 argumentative texts written by fifth and ninth graders. This then formed the basis for the development of corresponding computational linguistic procedures. The article focuses on the special features as well as the challenges that arose in connection with the annotation of learner texts and the generation of learner-sensitive feedback. The article is structured as follows: First, the relevant computational linguistics and language didactics research findings and digital support systems for argumentative writing are outlined. In the main part, the procedure of multi-level annotation is explained in detail. Due to the methodological approach, above-average inter-annotator agreement was achieved resulting in the multi-level approach implemented being adaptable for further corpus-based studies. Finally, the results are interpreted and discussed.

Extraembryonic endoderm (XEN) cells can be derived from blastocyst primitive endoderm (PrE), becoming a useful tool for studying mammalian development, including early lineage segregation and embryo patterning. Establishment of stem cells representing the respective lineages in blastocysts has been robustly attempted in domestic animals, especially pigs, to reconstitute embryogenesis in vitro for comparative studies. Therefore, we developed a serum-free culture system for pig XEN cells by dissecting the signals governing the core gene network of the PrE lineage. The FGF, LIF, and WNT signaling pathways and B27 supplements are essential for maintaining rapid proliferation rate in pig XEN cells. These cells recapitulated the molecular features and differentiation capacity of PrE lineage. Especially, the XEN cells incorporated into normal development, retaining the cellular identity and contributing PrE lineage when injected into in vitro-produced porcine blastocysts. In addition, species-specific characteristics of pigs were observed, including the involvement of lipid metabolism and NANOG/GATA co-expression in XEN cells. Taken together, our findings can contribute to the expansion of the understanding of developmental biology and its biomedical applications by enabling reproducible and homogenous porcine XEN cell culture.

Published: February 2025

The objective of this work was to investigate the effect on cell viability of radiolabeled complexes of cisplatin and carboplatin in cancer cells of the 4T1 and MDA-MB-231 lines from mice with mammary carcinoma. The complexes were labeled in the CDTN's TRIGA Mark I nuclear research reactor after 3 hours of irradiation. The analyzes were carried out after decay times of 1h and 24h. The results showed a more effective action of cisplatin compared to carboplatin in both cell lines and greater resistance in MDA-MB-231 cells. The additional effect of radiation was more evident in conditions of low resistance. Increasing the final activity of labeled compounds can amplify this effect. Investigations in this regard are underway.

Authors: Zhang Yimeng , Desai Nimai , Connolly Derek
Published: February 2025

The use of apabetalone, a novel therapeutic agent targeting epigenetic regulation, has been the source of much interest in its ability to subvert major adverse cardiovascular events. Derived from BETonMACE, clinical trials have explored its potential benefits in improving cardiovascular health. Apabetalone operates through selective inhibition of bromodomain and extra-terminal domain proteins, influencing gene expression and cellular pathways implicated in cardiovascular disease progression to influence lipid metabolism, downplay oxidative burden and reduce inflammation. The BETonMACE trial recruited patients with type 2 diabetes and recent acute coronary syndrome events. The primary endpoint was the composite of cardiovascular death, MI and stroke. This article explores the various clinical research and outcomes related to apabetalone and its use in the context of its proposed mechanism.

The Resilience and Vulnerability of Hungarian Eldercare Workers Abroad in the Light of Covid
Authors: Turai Tünde
Published: February 2025

Resilience, adaptation, survival, endurance, change, transformation, imbalance – these are all responses to crisis situations and social and economic stresses that are increasingly becoming the focus of academic and public interest. The Carpathian Basin is constantly exposed to strong external influences, to which the local communities, households, and individuals must respond in order to regain their balance, or to transition to a new mode of functioning. In the last three to four decades labor migration became one of the most prominent responses to economic and social pressures and a coping strategy. The convertibility of inequalities and resources between different regions is an opportunity for stabilizing the state of insecurity at home. For the last few years, it has been a common preconception in resilience theories that only strong entities are capable of resilience. Recent research shows that resilience and vulnerability are not mutually exclusive; I offer case studies which illustrate this point. I draw on 15 years of fieldwork with Central and Eastern European migrant women working as care workers in Western countries and Israel. These cases show that the experience of vulnerability and the skills and knowledge gained from it contribute to increasing flexibility, adaptability, and learning capacity, and thus practically lay the foundation for resilient behavior. My research also explores the controversial issue in resilience theories of how responsibility is constituted; i.e., whether the idea of resilience is related to the shifting of responsibility from the social classes in power to the vulnerable groups more prone to disequilibrium. In examining foreign women integrated into the low-level segment of the occupational structure, eldercare, I find that if their physical or mental condition deteriorates, and they are on their own, their vulnerability increases, and the disequilibrium resulting from systemic problems can no longer be corrected through individual resourcefulness alone.

Published: February 2025

Two Muscat grapes, Zaoheibao and Xiahei, with strong aroma were selected, co-fermented with Cabernet Sauvignon grapes (CFZ and CFX) in different proportions, and dried (CZD and and CXD). The physicochemical characteristics, colour, and volatile compounds in wine samples were measured. Compared with Cabernet Sauvignon wine, drying reduced the aroma compounds and colour but increased phenols content, improving overall quality based on sensory evaluation, especially for Zaoheibao (CZD, 3:1), which obtained the highest sensory score accompanied by increased rose oxide and phenols contents. Regarding Xiahei wine, different treatments had different effects. CFX wines co-fermented in a ratio of 1:3 and 3:1 have prominent aroma compounds. After drying, CXD wines co-fermented in a ratio of 3:1 have a more prominent taste. This research puts forward new innovation points and makes an in-depth analysis and research on specific problems.

Authors: Pryimakov Oleksandr , Sawczuk Marek , Korobeynikov Georgiy , Mazurok Nataliya , Omelchuk Olena
Published: February 2025

Background and Study Aim. The objective of this work is to study intra- and intergroup interrelations of parameters of physical development (PD) structure and speed-strength fitness (SSF) of highly skilled combat athletes.
Material and Methods. The research was conducted on 44 highly skilled athletes aged 18–30 years, members of the national teams of Ukraine in Greco-Roman and freestyle wrestling, and judo. Most of them were students. In the course of studies, 39 PD and 11 physical fitness (PF) indices were recorded. Of the PD parameters, the circumferential (CBD) and transverse body dimensions, and skinfold (SF) thickness were registered, whereas of the PF parameters — indices of SSF and special work capacity of combat athletes. The methods of factor, correlation, regression, and canonical analysis were used to process and analyze the experimental material.
Results. Statistical analysis revealed three key factors determining the general structure of PD and PF of combat athletes: 1) the factor of CBD; 2) the factor of SSF; 3) the factor of SF thickness and the total level of the fat component. As a result of stepwise regression analysis, multiple regression models characterizing the influence of the key PD and SSF indices on the level of special work capacity of combat athletes were developed. Canonical analysis of interrelations between the parameters of SSF and CBD revealed a high interdependence, indicating that the increase in the CBD of combat athletes contributes to the increase in their SSF and vice versa—the increase in SSF contributes to the increase in CBD. A moderate interdependence was disclosed between the parameters of SF and SSF, explaining the variability of a relatively small part of one group’s parameters when changing the parameters of the other group. The results of the interaction between SF and CBD indicate that the SF thickness indices show a low dependence on the changes in CBD, whereas the latter demonstrates a strong dependence on SF thickness.
Conclusions. The key factors of the structure of PD and PF of combat athletes include CBD, SSF, and SF thickness. As a result of the canonical analysis: 1) the specificity of mutual influence and interrelations of the CBD, SSF, and SF indices was determined; 2) the key factors and indices determining the general variability (redundancy) of the parameters of each group under study were revealed; 3) strong, moderate, and weak intra- and intergroup paired interrelations of the CBD, SF thickness, and SSF indices were disclosed. The strongest intra-group interrelations are manifested between the CBD indices, whereas the strongest inter-group interrelations are between the CBD and SF thickness indices.
Białoruś i Polska – od historycznych korzeni matryc instytucjonalnych do instytucjonalnego planowania
Authors: Pieczewski Andrzej , Sidarava Aliaksandra
Published: February 2025

Matryce instytucjonalne współczesnej Białorusi i Polski są efektem procesu historycznego. Mimo bliskiego sąsiedztwa i wspólnej historii kraje te to obecnie dwa zupełnie różne systemy instytucjonalne. Celem artykułu jest określenie słabych i mocnych stron matryc instytucjonalnych Białorusi i Polski oraz wskazanie szans i zagrożeń wynikających ze specyfiki funkcjonujących w tych krajach dominujących instytucji. Na podstawie tej analizy próbujemy określić kierunki pożądanych zmian instytucjonalnych zwiększających efektywność systemu polityczno-ekonomiczno-społecznego. Nasze rekomendacje skupiają się na najtrudniejszym obszarze – płaszczyźnie ideologicznej, kształtowanej przez zestaw instytucji nieformalnych wyrastających z narodowej kultury w trakcie procesu historycznego. Stworzenie rekomendacji przemian instytucjonalnych dla tego obszaru to trudne wyzwanie, gdyż kierunki zmian zależne są w istocie od wartości, jakimi się kierujemy. Aksjologiczna polaryzacja systemów instytucjonalnych (szczególnie zaś politycznego) tych krajów jest bardzo rozległa. O ile jesteśmy w stanie wskazać pożądane kierunki zmian mentalności dla Polski (i wskazujemy je), o tyle z tzw. zachodniego punktu widzenia dla Białorusi należałoby całkowicie zmienić aksjologiczne podstawy systemu politycznego i gospodarczego. Potwierdza to tezę głoszącą, że kultura stanowi podstawę systemów polityczno-społeczno-gospodarczych, choć w przypadku obu krajów kontekst geopolityczny również ma niebagatelne znaczenie.

A DESQUALIFICAÇÃO DO AUTISTA PELO DISCURSO RELIGIOSO
Authors: Vieira de Freitas Rodrigo , Brito de Assis Freitas Janaína
Published: February 2025

Este artigo investiga o impacto de discursos religiosos que desqualificam o autismo, associando-o a influências malignas, e como essas narrativas contribuem para o estigma e a exclusão simbólica de crianças autistas no ambiente escolar. A análise crítica fundamenta-se em conceitos como o estigma e a identidade deteriorada (Goffman), o sofrimento ético-político (Sawaia) e a neurodiversidade (Singer), visando entender como o discurso religioso reforça uma “inclusão perversa” que tolera a presença física dos autistas sem aceitar plenamente sua identidade. O estudo revela a necessidade de práticas educacionais que respeitem a neurodiversidade e promovam uma inclusão genuína e sem imposições de normatividade, proporcionando um ambiente acolhedor e adaptado às especificidades dos indivíduos neurodiversos.
INVESTINDO NA ESCOLA
Authors: Couto Vinicius
Published: February 2025

O presente artigo investiga as posições de Martinho Lutero quanto à reforma na área da educação. O que precisava ser feito para que uma reforma educacional ocorresse efetivamente na Alemanha quinhentista? A hipótese que sustenta esse trabalho é que Lutero fez a leitura de mundo encontrando necessidades de investimento escolar, políticas públicas transeuntes, responsabilidade pela educação do Estado e não mais da Igreja e conscientização da população quanto à importância de se enviar os jovens para estudar. Nosso objetivo é investigar as principais propostas de Lutero para a reforma educacional na Alemanha dos Quinhentos e nossos objetivos específicos são três: (1) entender como a educação alemã funcionava no período predecessor à Reforma Protestante; (2) avaliar a amplitude do movimento de reforma para além da religião, a partir do recorte da educação; e (3) analisar os pensamentos de Lutero concernentes à educação a partir de suas principais fontes primárias. A justificativa dessa pesquisa vai na direção de que a Reforma Protestante alemã é majoritariamente estudada sob o prisma religioso e teológico, mas possui importantes narrativas educacionais que ainda se relacionam com a realidade brasileira do século XXI. A fundamentação teórica desta pesquisa se concentra nas obras de Lutero (1987, 1988 e 1995) e em estudiosos do recorte educacional da reforma luterana, como Arnold (2019), Jardilino (2009) e Zabilka (1969). Nossa metodologia é bibliográfica e documental, com método exploratório. O resultado esperado é que este artigo possa contribuir com os estudos historiográficos da educação na Reforma Protestante e que seja relevante para as interfaces com o presente século.

Published: February 2025

The purpose of this study is to fabricate composites based on poly(lactic acid) (PLA), thermoplastic starch (TPS) and TiO2 nanoparticles (n-TiO2), and to investigate the effects of TiO2 on the interface compatibility of TPS and PLA. The FTIR spectra confirmed that the interfacial interaction between the components is the formation of hydrogen bonding between TiO2 and PLA/TPS matrix (Ti-O-C bond). The results indicated that the tensile properties of PLA/TPS blends were strongly influenced by the PLA/TPS ratio which decreased with increasing TPS content. Besides, the tensile strength of the composites was improved in the presence of n-TiO2 particles due to the high crystallinity of the PLA/TPS/n-TiO2­ composites (with an n-TiO2 content of 1 wt.%) in comparison with the PLA/TPS blends as shown in DSC and XRD analysis. The TGA results also indicated that the thermal stability of the PLA/TPS/n-TiO2 composites was improved with the addition of TiO2 nanoparticles. Finally, SEM images indicated that TiO2 nanoparticles were well dispersed in the PLA/TPS matrix at low TiO2 content. At high TiO­2 content (2 wt.%) it caused agglomeration into clusters which reduced the properties of the composites.
Optimization of variable-direction long-range trajectory for the unpowered flight vehicle
Authors: Pham Tuan Hung , Nguyen Duc Cuong
Published: February 2025

The study presents a new problem of trajectory for unpowered flight vehicles. The research object includes fixed-wing unpowered flight vehicles operating in the range of transonic and subsonic speeds. The purpose is to find the maximum range when unpowered flight vehicles have to perform the trajectory with direction change. In this study, the flight direction angle at the initial point of the trajectory is a right angle to the target line and the angle at the final point is also a right angle but in an opposite direction. The research focuses on considering the trajectory optimization problem in the horizontal plane according to the criterion of maximum range. It is known that a maximum range of a hundred kilometers can be achieved by fixed-wing unpowered flight vehicles when dropped from an altitude of about ten kilometers at transonic speeds to the target directly. Based on a trajectory scheme and conditions of the trajectory in the vertical plane, this study has optimized the trajectory with direction changes in the horizontal plane. The result obtained is a maximum range of about eighty kilometers. Although this range may be shorter than the previous study by ten kilometers, it opens up new potential applications for fixed-wing unpowered flight vehicles such as their capability for long-range multiple trajectories.

Published: February 2025

In this study, titanium dioxide-reduced graphene oxide (TiO2-rGO(TGO)) nanocomposite was synthesized via hydrothermal pathway. The characterization of the fabricated material revealed an efficient incorporation of the two constituents, as well as a notable decrease in the band gap energy of TGO compared to that of pristine TiO2 (2.62 versus 3.15 eV, respectively), which can expand the absorption spectrum of the catalyst towards the visible region. Electrochemical studies also elucidated the contribution of the rGO substrate in prolonging the recombination rate of charge carriers, signifying a noticeable enhancement in the photocatalytic capability of the TGO composite. Meanwhile, the hydrogen peroxide evolution performance of the synthesized photocatalyst was relatively promising with a concentration of up to 158.34 μM after 180 min. Along with further examinations additionally showing the plausible formation and participation of reactive oxygen radicals during the photocatalytic scheme, the TGO material indicates a good potential for several practical applications, especially the generation of hydrogen peroxide under light irradiation.
Study on temperature field and residual stress in T welding joint of stainless steel
Authors: Nguyen Tien Duong
Published: February 2025

The stainless steel used more and more popularity in the construction and transport sector because they combine favorable aesthetic aspects, good mechanical properties and corrosion resistance. Hence, the stainless steel structures have a high long-life with low maintenance costs. The local heating and cooling during welding produce a non-uniform temperature distribution. Uneven shrinkage of the welded joint creates residual stress in welded structures. This paper studies the temperature field during welding and the residual stresses after welding in T welding joint of stainless steel by the imaginary force method and the finite element analysis. The thickness of SUS316L stainless steel plate in T-joint is 10 mm. Two welds on both sides of the T-joint are welded simultaneously by the MIG welding process. In this study, ESI SYSWELD finite element software is applied for thermo-mechanical analysis of stainless steel T welding joint. The residual stresses of this welding joint are calculated by the theory based on the imaginary force method. The results of temperature field and residual stresses in the T-joint are presented and discussed. The results of residual stresses by finite element method are compared with the results of residual stresses by the imaginary force method. The residual stress results that are determined by the finite element method are compared with the residual stress results that are calculated by the imaginary force method.
Levels, profiles, and distribution of perfluoroalkyl substances (PFASs) in groundwater in Bac Ninh province, Viet Nam
Authors: Thi Vi Phung , Thuy Ngoc Nguyen , Thanh Dam Nguyen , Hung Viet Pham , Hong Anh Duong
Published: February 2025

Paper-making is one of the potential sources of PFASs contamination in groundwater because the collection and treatment of sewage from paper-making activities have not been controlled effectively. For this reason, in this study, 12 PFASs in groundwater were analyzed during the dry season (n = 18) and the rainy season (n = 22) in Phong Khe (Bac Ninh), the largest paper-making village in Northern Vietnam. The results showed that the total PFAS concentrations ranged from non-detectable levels to 15.06 ng/L during the dry season and from non-detectable levels to 9.92 ng/L during the rainy season. Short-chain PFASs (C < 9) were more commonly detected in groundwater compared to long-chain PFASs. While perfluorohexane sulfonic acid (PFHxS) and perfluorooctanesulfonic acid (PFOS) were predominant in groundwater samples during the dry season, perfluorooctanoic acid (PFOA), perfluorohexanoic acid (PFHxA), and perfluoroheptanoic acid (PFHpA) contributed significantly to the composition of PFASs during the rainy season. Although these PFASs have not posed a health risk through groundwater consumption, future research is needed to investigate further the levels and distribution of these compounds in different environmental compartments within other potential craft villages.

Introduction: Patients in intensive care units often experience a decline in oral health. Systematic reports of oral findings in these patients are scarce. Objective: To document oral cavity lesions in patients in Intensive Care Units. Materials and Methods: A systematic review was conducted, with a literature search across five databases, focusing on publications from 2018 to 2023. The identified articles were imported into the Mendeley reference manager; titles and abstracts were reviewed in pairs and under blinded conditions. Pre-selected articles were exported to the Rayyan application for eligibility assessment. Quality of the studies was assessed using the Joanna Briggs Institute (JBI) tool. This research is classified as risk-free and complies with copyright regulations by exercising citation rights (Law 1915 of 2018 and Law 1032 of 2006). Results: A total of 1553 articles were identified. Using the PRISMA methodology, 11 studies were included, with 54% retrieved from PubMed and 91% published in English. Toothbrushing was the most frequently documented oral care procedure. Gingivitis and ulcers were the most frequent oral findings. Discussion: The literature confirms the presence of oral findings in these patients, which are related to their systemic health status, procedures, equipment, and oral health care protocols. Conclusion: Although oral care is provided at a high rate in critically ill patients, oral alterations and lesions are frequently observed. The involvement of a dentist is essential for the comprehensive care of these patients.

Published: February 2025

In the global production of sunflower, the share of large-seed and confectionary varieties is constantly increasing due to their high nutritional value. In many countries, the replacement of varieties with high-yield confectionery hybrids is being actively implemented to increase the cultivated area. In Ukraine, to satisfy the high demand for confectionery sunflower, large-sized fractions of oilseed varieties and hybrids are usually used, but such raw materials often do not meet the requirements due to their biochemical composition, therefore the use and cultivation of varieties and hybrids of the confectionery type is being actively developed. In the article, a comparative analysis of the indicators of seeds and kernels, which determine the taste qualities and usefulness for health when consumed as food, is carried out in different varieties and hybrids of sunflower. As a result of the study, it was established that among the six genotypes studied, the highest values of the weight of 1000 seeds and kernels were the ʻZaporizkyi kondyterskyi᾿ variety, 121.7 g and 82.5 g, respectively. High values according to these indicators, which correspond to the demands of the confectionery and food industries, were obtained by the confectionery variety `Kamelot᾿ and hybrids `Smak' and `Kosmos'. It was found that the oil hybrid `Rehion᾿ (51.3%) and the variety `Prometei' (49.7%) had the highest oil content in the seeds, the confectionery hybrids `Smak' (20.2%) and `Kosmos' (20.2%) were characterized by the highest protein content, and the total amount of oil and protein in the seeds of all studied genotypes exceeded 60%. The highest values of oil (52.2 g) and protein (19.1 g) per 1,000 kernels were found in the ʻZaporizkyi kondyterskyi᾿ variety. The highest yield of 3.02 t/ha was obtained in the `Kamelot' variety, which also provided the highest yield of kernels of 2.26 t/ha of large size and the highest yield of 1.658 t/ha of total oil and protein per unit area of cultivation.
Study on Vascular Aging and Pharmaceutical Interventions
Authors:   University of Pittsburgh, USA1, Alex Hannah
Published: February 2025

Vascular aging is an age-dependent decline in vascular structure and function. It is one of the most critical determinants
of age-related cardiovascular diseases, including hypertensive and atherosclerotic diseases, frank arteriosclerosis,
arterial stiffness, and endothelial dysfunction. New findings offer an understanding of the mechanisms controlling the
aging process of blood vessels and point to drug possibilities.
Objective
To identify molecular factors contributing to end vessel aging or test compounds modulating vascular
stiffness/senescence markers.
Methods
Moreover, through the study of molecular changes in the RSC, the main mechanisms of the disease, such as oxidative
stress, extracellular matrix alterations, and endothelial cell senescence, were reviewed. New targeted therapeutic
strategies, including senolytics, antioxidants, and NO-targeting drugs, were evaluated.
Results
Some underlying expositions warrant further research, including mitochondrial imperfection, telomere shortening, and
a rise in pro-inflammatory molecules. Specific agents, such as resveratrol, quercetin, and statins, can potentially reduce
vascular stiffness and aging. Their effectiveness in trials has been demonstrated in their impact on oxidative stress and
endothelium.
Conclusion
Knowledge of the molecular mechanisms of vascular aging allows the creation of a pharmacological approach. AIM(s) focused on both senescence and oxidative stress pathways should be considered a paradigm shift in preventing elderly vascular diseases.

escalated energy consumption in data centers. AI-driven applications, including deep learning, natural language
processing, and autonomous systems, require substantial computing power, primarily provided by Graphics Processing
Units. These GPUs, while enhancing computational efficiency, contribute to significant power consumption and heat
generation, necessitating advanced cooling strategies. This study provides a quantitative assessment of AI-specific
hardware power usage, focusing on the NVIDIA H100 GPU. The analysis compares AI data center energy
consumption to the average US household power usage, demonstrating that a single AI rack consumes approximately
39 times the energy of a typical household. Additionally, a scalability analysis estimates that approximately 87 new
hyper-scale data centers consume the electricity as much as consumed by New York City. This emphasizes that with
rapid growth of AI Data Centers, the large-scale deployment could lead to an unprecedented rise in global energy demand. Furthermore, the study evaluates the impact of heat dissipation on cooling requirements, highlighting the need for energy- efficient cooling solutions, including liquid and immersion cooling techniques. Future research directions include energy- efficient AI models, renewable energy integration, sustainable AI accelerator designs, and intelligent workload optimization to mitigate the environmental impact of large-scale AI adoption. This research provides critical insights for designing more sustainable AI-driven data centers while maintaining high-performance computing efficiency.

The automotive door system's weather-strip seals play a crucial role in determining the degree of door
closure, sealing the passenger cabin from water, and reducing wind noise inside the vehicle. Wrinkles often occur when
installing weather-strips on door surfaces with bent or twisted profiles, affecting both the closure tightness and the
noise insulation properties of the car door system. This study characterizes the wrinkling of Ethylene Propylene Diene
Monomer (EPDM) automotive weather-strip seals during bending and identifies critical conditions for wrinkle
formation. The hyper elastic behaviour of the seal's EPDM sponge and dense EPDM rubber was modeled using the
Foam and Mooney-Rivlin models, respectively. A Finite Element Analysis (FEA) model of the automotive weatherstrip seal was then developed and analysed using the linear FEA software Abaqus to determine the deformation and
thickness reduction in areas prone to wrinkling. Finally, the critical criteria for wrinkle formation were determined
through reaction force analysis in these areas. The proposed analytical method significantly reduces the product design
cycle and cuts down on design and prototype costs.

ABSTRACT Background: The study aimed to assess the effectiveness of restoration practices following the Fundão disaster in the Brazilian Atlantic Forest, a key region for global biodiversity. Focusing on affected areas in Mariana, MG, the study used seed bank analysis as a key indicator to understand environmental recovery progress. The study compared active and passive restoration areas with a reference ecosystem by collecting 168 soil samples, which were subjected to germination in a greenhouse. Results: The results revealed a high germination rate of herbaceous seeds, predominantly native species. Significant differences were found in floristic composition among the different restoration types studied. Areas undergoing active restoration showed greater similarity to the reference ecosystem, emphasizing the importance of Distance from Forest Fragment, Percentage of Forest Area in the Surroundings, and species diversity for restoration success. Conclusion: The results highlight the crucial importance of landscape connectivity for the success of ecological restoration. Active restoration strategies play a fundamental role in accelerating environmental recovery and bringing degraded areas closer to the floristic composition of reference ecosystems.
Os prazeres da carne masculinizada: a fabricação midiática do deleite homoerótico no Brasil durante a Ditadura Civil-Militar
Authors: Maior Paulo Souto , Martinelli Leonardo
Published: February 2025

Resumo O presente artigo consiste na análise da emergência de padrões de beleza do corpo masculino, sobretudo no que diz respeito à cor da pele, divulgados na revista Rose, pioneira publicação de nus masculinos a circular no Brasil, entre 1979-1983. Foram selecionadas 27 edições do periódico para a análise e percebeu-se que o tipo físico produzido como atrativo e desejável difere do fabricado no final do século XX e nos dias de hoje. Observou-se, ainda, que modelos de cor preta eram pouco visíveis na revista, o que mobilizou uma discussão sobre uma história da beleza. Essa análise fundamenta-se nos estudos sobre masculinidades e a metodologia foi construída a partir da imbricação entre História e Imprensa.
Evaluating the importance and feasibility of the Preferences for Everyday Living Inventory-Korean (PELI-K): A cross-sectional study using the nursing home stakeholder advisory panel
Authors: Kwon Jenny Hyosun , Shin So Young
Published: February 2025

Purpose: As a follow-up study for the translation and cultural adaptation of the Preferences for Everyday Living Inventory-Korean (PELI-K), this pilot study aims to identify the ranking of the PELI-K items selected as most important/feasible from the original 72 items in Korean nursing homes (NHs) and to lay the groundwork for developing a revised short version of the instrument based on these rankings. Methods: The NH stakeholder advisory panel (n=34) consisting of an experts group (n=22) and a family group (n=12) was asked to complete a self-administered, in-person survey. Results: The top 10 important and top 11 feasible items are reported. Most notably, items related to human basic needs such as sleeping, safety, and privacy were selected as important priorities. Having regular contact with family and using electronic devices to communicate with others were the most feasible preferences. Conclusion: The results from this study will contribute to refining the PELI-K and creating a short version of the tool for wider use. NH providers may plan and deliver care that is geared toward residents’ most salient preferences.

Authors: Shin Yujeong , Jung Dukyoo , Oh Hyunjoo
Published: February 2025

Purpose: This study aimed to explore the hospitalization experiences of elderly surgical patients and understand the meaning of these experiences. Methods: Data were collected through individual in-depth interviews with 10 elderly patients who underwent general anesthesia surgery at Ewha Womans University Seoul Hospital and were analyzed using Colaizzi’s phenomenological analysis method. Results: Four theme clusters and ten themes were identified. The theme clusters were “Limitations faced due to aging,” including themes of cognitive and physical decline. “Psychological retreat after undergoing surgery” encompassed role loss, feelings of guilt, and a sense of alienation, respectively. “Loss of freedom in inpatient life after surgery” highlighted dietary restrictions and physical dependence and “Concerns about life after discharge” reflected uncertainties, burdens, and negative thoughts about life. Conclusion: This study underscores the need for holistic nursing interventions that address not only the physical but also the psychological and social needs of elderly surgical patients. It also emphasizes the importance of effective communication strategies, emotional support, and post-discharge care. These findings provide foundational data for the development of tailored nursing practices and policies for elderly surgical patients.

Objective. To conduct a comparative analysis of the results of liver biopsy for focal lesions in a short-term hospital setting. Material and methods. A retrospective analysis of liver biopsy performed in a short-stay hospital was conducted at the S.P. Botkin Hospital from 2022 to 2023. Biopsy was performed in 121 patients, 53 males and 68 females. The average age was 63.4±8.9 years, the average ECOG score was 1.2±0.4. The selection of patients was based on the criteria developed at Botkin Hospital for liver biopsy in a short-stay hospital (checklist). Results. Biopsy was performed in 121 patients: 1 biopsy was taken in 68 patients and 2 biopsies were taken in 53 patients. Histologic report with diagnosis was obtained in 114 (94.2%) patients, 7 (5.8%) patients required repeat biopsy. The total number of early complications was 11 (9.1%), 8 of them minor and 3 clinically significant. Among minor complications, pain syndrome was diagnosed in 4 (50%) patients, bleeding from the skin wound in 3 (37.5%), and local reaction to anesthetic in 1 (12.5%). Clinically significant complications were: hemoperitoneum — 1 (33.3%), subcapsular hematoma of the liver — 1 (33.3%), sharply expressed pain syndrome — 1 (33.3%). No deaths were recorded. Conclusion. Performing a liver biopsy in a short-stay hospital is a safe procedure and can therefore be used in other specialized oncology facilities.

The article presents a rare clinical case of sigmoid-rectal intussusception caused by a giant villous adenoma of the rectum. Clinical symptoms of the disease were manifested by mild pain in the lower abdomen, pain in the anus, partial intestinal obstruction with frequent loose stools. A tumor in the rectum was discovered during a routine digital rectal examination. Subsequent colonoscopic examination confirmed the presence of a tumor in the rectal ampulla, but did not detect intussusception. Computed tomography revealed the presence of sigmoid-rectal intussusception. Intraoperatively, it was possible to perform disinvagination with subsequent removal of the tumor and preservation of the rectum. After histological examination, the tumor was recognized as a giant villous adenoma. The postoperative period proceeded without complications, the patient was discharged in satisfactory condition with a functioning sigmoid stoma. Observation and examination over the next three months did not reveal further spread of the tumor process. The patient refused to have her stoma removed.
