Distributed Consensus Control for Discrete-Time T–S Fuzzy Multiple-Agent Systems Based on an Unknown Input Observer
Authors: Ling Xufeng , Xu Haichuan , Weng Weijie , Zhu Fanglai
Published: December 2024

This paper investigates a consensus problem for a class of T–S fuzzy multiple-agent systems (MASs) with unknown input (UI). To begin with, an unknown input observer (UIO) is able to asymptotically estimate the system state and the UI is designed for each agent. In order to construct the UIO, the state interval estimation is obtained by first using zonotope theory. Next, using the interval estimation of the state, a correlation of the state and the UI is built. Subsequently, a UIO is constructed, which is proposed by building upon the algebraic relationship. Moreover, by using the estimations of the state and the UI, a distributed control protocol is developed based on the proposed UIO. And, with the proposed distributed control protocol, the T–S fuzzy MAS can achieve consensus, in that all the states of the agents can converge to the leader’s state asymptotically. Finally, the effectiveness of the proposed method is demonstrated through two simulation examples.

Authors: Dardanou Maria , Brito Rita
Published: December 2024

The significance of family involvement in Early Childhood Education and Care has gained considerable attention within national reforms and regulations across various countries. This study aims to examine the early childhood education curriculum frameworks pertaining to family participation in Portugal and Norway. By analysing the national curriculum frameworks of these two countries, this study explores the distinct approaches they adopt towards family involvement in Early Childhood Education and Care, considering their unique cultural and policy contexts. Through content analysis of the curriculum frameworks from both nations, two primary themes emerge through coding: active involvement in the educational process and collaborative partnerships. The findings highlight the importance of fostering relationships between families and educational institutions to enhance children’s learning experiences and emphasize the necessity of ongoing communication and shared decision-making. Through an ecological perspective, this paper provides insights into how varying levels of family participation can influence educational practices and experiences in early childhood settings, suggesting potential improvements to strengthen partnerships between families and educators.

Published: December 2024

Analysing the patterns and impacts of land-use changes in the production–living–ecological space (PLES) of the Fenhe River Basin (FRB 39,721 km2), China, is necessary to support sustainable development. Based on remote sensing images from 1990 to 2020, we aimed to analyse the PLES land-use changes. Industrial production and living spaces continuously encroached on the agricultural production and ecological spaces between 1990 and 2022 owing to industrialisation and urbanisation, and the ecological land area decreased by 699.21 km2, while the industrial production land area increased by 521.32 km2. We used the soil and water assessment tool (SWAT) model to quantitatively analyse the impact of PLES changes on runoff in the FRB. With the continuous expansion of production and living spaces, the extensive use of concrete in cities has led to ground hardening, making it difficult for precipitation to infiltrate, with surface runoff increasing by 0.3 mm annually. The reduction in ecological space has led to a reduction in forests and grasslands, weakening the water-holding capacity of the watershed and affecting groundwater storage. This study provides a scientific basis for watershed management and the integrated development of PLES.

3D/4D printing technologies are currently among the fastest growing cutting-edge fabrication technologies. The scale of their applications is vast and applicable to nearly all industries. Three-dimensional printing technologies are particularly popular in robotics and especially in advanced design innovative solutions for areas such as manufacturing, space technology, and medicine. The development of robotics, and, in particular, of the precision of manufactured components, such as actuators, pneumatic muscles, power transmission units, etc., means that new prototypes are still being made, and the use of 3D printers reduces the production time severalfold, allowing for the completion of necessary simulations and tests. In addition, the use of 3D printers allows for the production of thin-walled and cellular structures, which is a great advantage compared to conventional fabrication technologies. In the range of 3D printers available on the market, only a few selected technologies allow for actual use in the construction of advanced robot elements (muscles, vibration dampers, etc.). In an era of rapid growth in the precision of available 3D printers and modern materials, 3D printing may soon become a major tool in robotics. This article presents an overview of 3D printing technologies and materials in terms of their application in robotics and provides examples of the use of 3D and 4D printing in prototyping and fabricating robotic elements with particular emphasis on the current state of the art. The study considered the possibilities of using 3D/4D printing in robotics with the use of polymeric materials. Three-dimensional and 4D printing technologies can have a major impact on achieving sustainable development goals by providing appropriate strategies to minimise health risks and promote environmentally friendly production processes. The review of the literature and the research work currently being carried out in this area is very promising and it seems that 3D/4D printing in robotics is widely used and is still developing, which allows us to conclude that in the near future the number of research works in this field will increase rapidly.

Assessing Public Transport Quality Using AHP and SUTI Indicator 4: A Case Study of the Sustainable Mobility Plan in Wrocław, Poland
Authors: Dziaduch Izabela , Peternek Piotr
Published: December 2024

Wrocław is the most congestion-challenged city in Poland. Improving the appeal of public transport over private car use could be an effective remedy for the city’s notorious congestion problems. This article evaluates public transport service quality in Wrocław from the passengers’ perspective. The quality assessment focused on two key areas: the quality of service that passengers expect (preference evaluation) and the quality they perceive are delivered by the transport organiser and operator (satisfaction evaluation). Both passenger preferences and satisfaction were assessed based on 14 selected transport service attributes, referred to as quality attributes. To carry out this analysis, the Analytic Hierarchy Process (AHP) method and the SUTI Indicator 4 (Public Transport Quality and Reliability), which is part of the Sustainable Urban Transport Index (SUTI), were employed. Data were collected via a survey questionnaire with a sample of 500 bus and tram users in the city. Statistical analysis of the data were performed using functions and commands available in Microsoft Excel. The resulting SUTI Indicator 4 values (42.6% for bus services and 45.9% for tram services) suggest that Wrocław residents are moderately satisfied with the current public transport system. The study reveals that the transport organiser and operator should prioritise attributes related to travel time, as their fulfilment levels are shown to be either low or moderate. Therefore, in order to encourage more car users to switch to public transport in Wrocław, emphasis should be placed on solutions that ensure punctual departures and provide passengers with greater confidence in reaching their destinations on time.
Study on the Impact of Renewable Energy Technology Innovation on Urban Green Development: A Case Study of the Beijing-Tianjin-Hebei Region
Authors: Tong Linjie , Qi Qinghua , Mu Qian
Published: December 2024

Renewable energy technology innovation (RETI) plays a vital role in transforming economic growth models and promoting urban green development (GD). This paper examines 13 cities at the prefectural level and above in the Beijing-Tianjin-Hebei region from 2008 to 2022, assessing the GD levels of these cities using the entropy weight TOPSIS method. The study investigates the effects and mechanisms of RETI on urban GD through fixed effect models, mediation effect models, and threshold effect models. The results indicate that (1) RETI significantly promotes urban GD in the Beijing-Tianjin-Hebei region, a conclusion that remains valid after conducting several robustness tests. (2) The promoting effect of RETI on urban GD exhibits heterogeneity based on urban resource endowments and spatial layouts, with a more pronounced positive impact in non-resource-based cities and core cities. (3) Mechanism analyses demonstrate that RETI indirectly promotes urban GD in the Beijing-Tianjin-Hebei region by facilitating the low-carbon upgrading of industrial structures and the transition to cleaner energy systems. (4) When R&D investment (RD) is lower than 0.0097, RETI has a clear inhibitory effect on urban GD, meaning that for every unit increase in RETI, the level of urban GD decreases by 0.355 units; when RD is between 0.0097 and 0.0375, RETI exerts a clear positive effect on urban GD, meaning that for every unit increase in RETI, the level of urban GD rises by 0.606 units; however, once RD exceeds 0.0375, the positive effect of RETI on urban GD begins to diminish. In this range, for every unit increase in RETI, the level of urban GD increases by only 0.170 units. When the green policy support index (GPSI) is lower than 0.0427, RETI has a clear promotion effect on urban GD, meaning that for every unit increase in RETI, the level of urban GD rises by 0.171 units; when the GPSI exceeds 0.0427, the promotion effect of RETI on urban GD is further strengthened, meaning that for every unit increase in RETI, the level of urban GD rises by 0.221 units.

Published: December 2024

New York State (NYS) is actively promoting the transition to a bioeconomy to address climate change, reduce greenhouse gas (GHG) emissions, and foster sustainable development. This study aims to evaluate the potential of NYS’s bioeconomy, as outlined in the scoping plan guided by the Climate Leadership and Community Protection Act (CLCPA), in achieving net-zero emissions by 2050. The primary objectives are to assess the bioeconomy’s role in meeting climate targets by quantifying its contributions to GHG mitigation and renewable energy integration and to propose a robust monitoring framework for tracking progress. The study also examines the socioeconomic benefits of bioeconomy initiatives, particularly for disadvantaged communities (DACs), and identifies key dimensions and indicators for sustainability monitoring. The hypothesis tested posits that an integrated bioeconomy strategy can simultaneously address environmental, social, and economic goals. Findings reveal that while biomass resources offer significant opportunities for GHG mitigation and economic growth, challenges remain in feedstock estimation, deployment readiness, and stakeholder coordination. A comprehensive monitoring framework is proposed to guide policy decisions and ensure alignment with sustainability objectives. This research provides actionable insights to advance NYS’s bioeconomy, emphasizing inclusivity, environmental stewardship, and resilience.
The Impact of Carbon Trading Policy on the Green Innovation Efficiency of Enterprises: Evidence from China
Authors: Zhang Shuwen , Ding Chenhui , Liu Chao
Published: December 2024

Improving green innovation efficiency (GIE) is crucial for reducing enterprise carbon emissions and fostering enterprise sustainability. Meanwhile. most of the research has not considered the micro-level influence of carbon trading on GIE. Therefore, the research objective of this paper is to assess the impact of carbon trading policy (CTP) on the GIE of enterprises and its specific mechanism. This paper uses data from China’s listed enterprises from 2010 to 2019 and treats the 2013 CTP in seven regions as a quasi-natural experiment. The Super-SBM model is applied to calculate the GIE. The difference-in-difference-in-differences (DDD) method assesses policy impact by comparing pre- and post-policy efficiencies. The results reveal that CTP improves the GIE of enterprises in high-carbon emission sectors in pilot areas. It primarily boosts GIE by increasing the environmental attention and resource allocation efficiency of enterprises. CTP significantly promotes the GIE of non-state-owned enterprises (non-SOEs), large-scale enterprises, and enterprises in regions with strict environmental regulations. Finally, policy recommendations are made for more environmentally friendly and sustainable enterprise development.

Published: December 2024

This study examines the effects of oil contamination on three soil types—podzolic, sod-gley, and alluvial—in Western Siberia’s middle taiga, assessing key physical and chemical properties and the influence of the surfactant Modified Syntherol (MS) on oil degradation. In controlled laboratory experiments, oil was introduced at 50, 100, and 150 g/kg concentrations. Results indicate a substantial increase in soil pH, most notably in podzolic soils, alongside a significant decline in cation exchange capacity (CEC). For example, CEC in podzolic soils dropped five-fold at higher contamination levels, reflecting a reduced ability to retain essential nutrients. The water retention capacity decreased in all soil types, with the most pronounced decline observed in alluvial soils’ capillary moisture levels. MS application did not accelerate oil degradation; even after 35 days, natural decomposition rates in untreated soils remained low (0.02–0.4%), underscoring the persistence of oil contaminants. Notably, podzolic soils showed the highest susceptibility to oil contamination due to their acidic and low-organic nature, in contrast to sod-gley and alluvial soils, which demonstrated moderate resilience. These findings highlight the need for soil-specific remediation approaches, as general methods may be ineffective for soils with differing vulnerabilities and recovery capacities. This research provides essential insights for developing effective, tailored strategies to address the environmental challenges of oil pollution, advancing sustainable soil management practices for sensitive taiga ecosystems.

Authors: Nishioka Koki , Fujiu Makoto , Morisaki Yuma
Published: December 2024

The Hokuriku Shinkansen is among the five main Shinkansen lines in Japan. It starts from the capital, Tokyo, and passes through the Hokuriku region (Nagano City, Toyama City, and Kanazawa City) before reaching the Kansai region (Kyoto City and Osaka City). In Japan, the Hokuriku Shinkansen is being developed to increase the number of visitors in the area by shortening travel times and ensuring transportation networks in the event of a disaster; the Kanazawa–Tsuruga extension was opened on Saturday, 16 March 2024. The shortened travel times with this opening are expected to increase the number of visitors to the Hokuriku region and other regions, such as the Tokyo metropolitan area. The Tsuruga extension opening will connect the Hokuriku region with the Tokyo metropolitan area through direct service; however, travel between the Kansai and Chukyo regions will require transfers at Tsuruga Station, which would reduce convenience. Consequently, the flow of people in the Hokuriku region is expected to change significantly after spring 2024. Therefore, this study conducted a questionnaire survey of Kanazawa residents in Ishikawa Prefecture prior to the opening of the Tsuruga extension to analyze its effect on the choice of modes of transportation for travel to the Kansai region. The Hokuriku Shinkansen was found to be the most popular route for travel to the Kansai region after the opening of the Tsuruga extension, and the Hokuriku Shinkansen users prioritized comfort during travel and shorter travel times. Moreover, a high proportion of Hokuriku Shinkansen users were unemployed and received pensions, whereas a high proportion of private automobile users were students, housewives, or other people with no income.

Temporal and Spatial Analysis of Trace Metal Ecotoxicity in Sediments of Chaohu Lake, China
Authors: Luo Wenguang , Li Zongjun , Yi Ran , Han Lijuan , Zhu Senlin
Published: December 2024

The species sensitivity distribution (SSD) analysis for aquatic ecosystems has been increasingly used in risk assessment. However, existing analyses of the impact of trace metals in lake sediments on aquatic organisms often neglect the spatiotemporal variability of trace metal release. This oversight can result in ecological risk assessments that lack specificity. To address this gap, we collected 32 core sediment samples from Lake Chaohu to systematically investigate the ecological toxicological risks posed by the release of eight trace metal indicators into the overlying water column under four hydrological scenarios throughout the year. Results indicated that only Cu, Pb, and Zn exhibit persistent toxicological risks. The comprehensive ecological toxicological risk of sediment trace metals showed spatial differences, increasing from the western region to the eastern region, i.e., western region < central region < eastern region. Seasonally, the risk levels are ordered as follows: May < September < November to April of the following year < June to August. The eastern region in summer (June to August) was identified as the high-risk area and period for trace metal pollution in sediments. Based on these conclusions, it is recommended to implement pollution control and environmental monitoring measures in the eastern region during the summer to effectively control the pollution and ecological risks of trace metals.

Methanol is a widely used industrial and household alcohol that poses significant health risks upon exposure. Despite its extensive use, methanol poisoning remains a critical public health concern globally, often resulting from accidental or intentional ingestion and outbreaks linked to contaminated beverages. Methanol toxicity stems from its metabolic conversion to formaldehyde and formic acid, leading to severe metabolic acidosis and multiorgan damage, including profound CNS effects and visual impairments. Epidemiological data underscore the widespread impact of methanol poisoning, with alarming case fatality rates reported in various countries. Comprehensive prevention and effective management strategies are urgently needed to address the significant morbidity and mortality associated with methanol poisoning. The clinical manifestations of methanol toxicity vary between adult and pediatric populations and between acute and chronic exposure. Adults typically present with gastrointestinal and neurological symptoms, whereas pediatric patients often exhibit more severe outcomes due to differences in metabolism and body weight. The diagnosis of methanol poisoning involves a combination of clinical evaluation, laboratory testing, and advanced diagnostic techniques. The identification of metabolic acidosis, elevated anion and osmolal gaps, and confirmation through methanol and formate levels are critical for accurate diagnosis. Timely intervention is crucial, and the management of methanol poisoning includes securing the airway, breathing, and circulation; addressing metabolic acidosis with sodium bicarbonate; administering antidotes such as fomepizole or ethanol; and administering hemodialysis, which plays a pivotal role in eliminating methanol and its toxic metabolites, especially in severe cases. The complexity of methanol poisoning necessitates a comprehensive approach encompassing early recognition, prompt intervention, and coordinated care among healthcare providers. Increased awareness, effective prevention strategies, and timely treatment protocols are essential to mitigate severe health consequences and improve patient survival and recovery.
Long-Term Hydrological Impacts of Land Use Change and Evaluation of Best Management Practices from 2000 to 2020 in the Hulan River Basin, Northeast China

Published: December 2024

The alterations in runoff resulting from changes in land use and land cover (LULC) were the primary influencing factors contributing to non-point source pollution (NPS). In order to evaluate the long-term hydrological consequences of LULC for the purposes of land use optimization in the Hulan River Basin, Northeast China, the validated Long-term Hydrological Impact Assessment (L-THIA) model was employed to simulate the spatiotemporal distribution of total nitrogen (TN) and total phosphorus (TP) non-point source (NPS) loads from 2000 to 2020. Additionally, the load per unit area index (LPUAI) method was utilized to identify critical source areas. The findings indicated that the regions with elevated pollution levels were predominantly situated in areas designated for agricultural and construction activities. The greatest contributor to nitrogen and phosphorus loads was agricultural land. There were clear increases in both TN and TP during the study period, with increases of 51.73% and 55.56%, respectively. As a consequence of the process of urbanization in the basin, the area of land devoted to construction activities increased, reaching a coverage of 5.02%. Nevertheless, the contribution of construction land to the total basin NPS load exceeded 10% in 2020. This was the primary factor contributing to the observed increase in pollution loads despite a reduction in agricultural land area over the past two decades. TN and TP loads were markedly higher during the flood season than the non-flood season, accounting for over 80% of the NPS load. The sub-watersheds in the southwest and northeast have been identified as significant sources of nitrogen and phosphorus loss, contributing to the overall burden of NPS pollution. Implementing measures such as fertilizer reduction and conversion of farmlands to forests and grasslands can effectively mitigate NPS pollution, particularly TN pollution. This study proposes that the integration of L-THIA with GIS can serve as a valuable tool for local planners to consider potential pollution risks during future planning and development activities.

Published: December 2024

Wastewater accumulates debris as it moves through sewage systems and must undergo purification at treatment plants, where insoluble debris is screened at the inlet. Previous studies have focused on screening mechanisms using rotating or ascendible sub-screens with vertical bars, and the effects of horizontal bars on structural integrity and fluid flow have not yet been explored. The present study addresses this gap by proposing a novel screening mechanism with horizontal bars and providing insights into flow behaviour and structural performance. The proposed mechanism consists of a main screen, an ascendible sub-screen and a rake system, and its effects on the flow distribution inside the channel and the resulting deformations and stress affecting the mechanism are computationally analysed. The problem is modelled as a fluid–structure interaction and solved using the arbitrary Lagrangian–Eulerian approach. Velocity distribution, structural deformation and stress are analysed for the various inlet flow velocities and critical configurations of the screening mechanism. The sub-screen in the proposed mechanism exhibited reduced deformation (0.9 mm for vertical bars and 0.2 mm for horizontal bars versus 2.2 mm in previous vertical-only designs). The maximum von Mises stress values were well below the 250 MPa yield strength, with peak stresses of 3.8 MPa in the sub-screen and 0.23 MPa in the main screen. Key operating conditions causing flow separation and velocity fluctuations are identified, and design improvements are suggested. The study provides guidelines for manufacturing and operating wastewater-screening mechanisms whilst mitigating undesirable performance and minimising deformation and stress in the mechanism.

Published: December 2024

The spatial heterogeneity of soil nutrients is crucial for the water bird and whole floodplain wetland ecosystem in large lakes, and it is influenced by the dramatic water level changes and sedimentation progress in West Dongting Lake (WDL). Soil samples were collected at various soil depths along the Yuan River and Li River that feed into WDL. The concentrations of soil total organic carbon (TOC), total nitrogen (TN), total phosphorus (TP), and soil grain size were tested. The stoichiometric ratios of C, N, P, and the mean value of soil grain size (Mz) were calculated. The differences of soil TOC, TN, TP and the stoichiometric ratio at different sites and soil depths were compared. Linear regression was used to explore the relationships of Mz and nutrient concentrations, and relationships between TOC, TN, and TP. Redundancy analysis was used to explore the relationship between soil nutrients, heavy metal concentrations, and plant community diversity. The results showed that the distributions of soil TOC, TN, and TP concentrations differed across regions in west Dongting Lake along the Yuan and Li Rivers. Total organic carbon concentration differed at different sedimentation depths. Soil grain size showed negative effect with soil TOC, TN, and TP concentrations in this region. Plant community diversity correlated positively with soil TOC and negatively with Hg. West Dongting Lake was N limited despite the high wet deposition of N. It could potentially be attributed to the insufficient presence of aerobic environments for microbes during intermittent flooding of the floodplain, coupled with feeble mineralization. This study can provide valuable insights for the conservation of water bird habitats and wetland ecosystems.

Published: December 2024

The increasing presence of compostable bioplastics as substitutes for conventional fossil-based plastics necessitates a deeper understanding of their environmental impacts, particularly in marine ecosystems, where they often accumulate. This study examines the leaching potential of different phthalic acid esters (PAEs) from commercial biodegradable plastic bags into natural seawater over a three-month period. Degradation experiments were conducted to investigate the release of PAEs under direct solar radiation exposure and in shielded conditions. 1H-NMR analysis of the seawater confirmed the release of phthalates, with higher concentrations observed in the samples exposed to sunlight. The leaching rate ranged from 264–342 microgram/g plastic under light exposure to 20–167 microgram/g in dark conditions. These results indicate that the accumulation of compostable plastic waste in coastal marine environments leads to the release of phthalic acid esters, with potential implications for marine ecosystem health and human exposure to these emerging contaminants.

Published: December 2024

As the global shift from fossil fuels to the Paris Agreement has accelerated, wind energy has become a key alternative to hydroelectric power. However, existing research often needs to improve in integrating diverse environmental, economic, and climate-related variables when modeling wind energy potential, particularly under future climate change scenarios. Addressing these gaps, this study employs the maximum entropy (MaxEnt) method, a robust and innovative tool for spatial modeling, to identify optimal wind farm sites in Türkiye. This research advances site selection methodologies and enhances predictive accuracy by leveraging a comprehensive dataset and incorporating climate change scenarios. The results indicate that 89% of the current licensed projects will maintain compliance in the future, while 8% will see a decrease in compliance. Furthermore, the wind energy potential in Türkiye is expected to increase because of climate change. These results confirm the suitability of existing project locations and identify new high-potential areas for sustainable wind energy development. This study provides policymakers, investors, and developers actionable insights to optimize wind energy integration into the national energy portfolio, supporting global climate goals by accelerating the adoption of renewable energy sources.

Published: December 2024

The overuse of antibiotics in human society poses a global health challenge, necessitating effective treatment of antibiotic production wastewater. This study examines the microbial community within activated sludge in anaerobic digestion (AD) and biological nutrient removal (BNR) systems at a full-scale oxytetracycline production wastewater treatment plant. The AD system effectively degraded polysaccharides but accumulated refractory humic-like substances, as determined by excitation–emission matrix fluorescence spectroscopy. Metagenomic analysis revealed distinct microbial communities between the AD and BNR systems, with Bacteroides (13.9%) and Proteiniphilum (33.5%) as the most abundant genus in the AD and BNR systems, respectively. Functional gene analysis showed a high presence of carbohydrate binding and glycoside hydrolases. The low abundance of nitrite oxidizer and the nxr gene might explain nitrite accumulation in the BNR system via partial nitrification. The antibiotic resistance genes (ARGs) affiliated with tetracycline were dominant in both the AD and BNR systems, with 45% of tetracycline and 20% of total ARGs being efficiently removed during the anaerobic treatment. The findings of this study can provide insights into microbial response to oxytetracycline production wastewater, informing the optimization of biological treatment processes and mitigating the environmental impacts of antibiotic production.

Purpose: Diagnosing sarcopenia necessitates the measurement of skeletal muscle mass. However, guidelines lack a standardized imaging modality with thresholds validated among Asians. This systematic review compared ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI), and bioelectrical impedance analysis (BIA)/body composition monitoring in the detection of sarcopenia within Asian populations.Methods: PubMed and Embase were systematically searched for studies analyzing ultrasonography, CT, MRI, and BIA in diagnosing sarcopenia among Asians. Study quality was assessed using the Newcastle-Ottawa scale.Results: Pooled findings from 21,598 patients across 25 studies were examined. In receiver operating characteristic analysis, ultrasound displayed a pooled mean area under the curve (AUC) of 0.767 (95% confidence interval [CI], 0.709–0.806), with mean sensitivity of 81.1% (95% CI, 0.744–0.846) and specificity of 73.1% (95% CI, 0.648–0.774), for detecting sarcopenia in Asian populations. CT exhibited an AUC of 0.720 (sensitivity, 54.0%; specificity, 92.0%). MRI demonstrated an AUC of 0.839 (sensitivity, 67.0%; specificity, 66.0%). BIA displayed an AUC of 0.905 (95% CI, 0.842–0.968), 80.7% sensitivity (95% CI, 0.129–0.679), and 82.4% specificity (95% CI, 0.191–0.633).Conclusion: Various modalities aid in diagnosing sarcopenia, and selection should be individualized. Although only BIA and dual-energy x-ray absorptiometry are recommended by the Asian Working Group for Sarcopenia and the European Working Group on Sarcopenia in Older People, ultrasound imaging may hold diagnostic value for sarcopenia in the Asian population. In certain groups, diagnostic use of CT and MRI is warranted. Future research can standardize and validate modality-specific thresholds and protocols within Asian populations.

El texto se centra en la métrica del offshoring entre Estados Unidos y México durante 2013-2018, mediante el uso de tablas insumo producto inter-países. La medida es concebida como un proceso en el cual las actividades productivas –y no solo las empresas— se trasladan a ciertas economías del mundo, que gozan de mayores ventajas comparativas para explotarlas, y se retiran de aquellas otras que carecen de ellas (Gao, 2018). La medida distingue tres componentes impulsores: 1) por insumos intermedios; 2) por bienes finales; y 3) por existencia de vínculos indirectos con la industria intermedia de los bienes finales. Empíricamente, la magnitud monetaria del offshoring en los Estados Unidos asciende a 62 mmd y en México apenas supera 1 mmd en este periodo.
Da Revolução Gerencial de J. Burnham ao capitalismo gerencial de G. Duménil & D. Lévy: a persistência da apologia indireta ao capitalismo pela doutrina gerencialista como variante da ideologia da terceira via
Authors:   , Paiva Felipe Acácio de
Published: December 2024

O objetivo da presente dissertação foi analisar a continuidade da apologia indireta ao capitalismo na assim chamada “doutrina gerencialista” ou teoria dos gestores na qual estes seriam uma nova e dominante classe social na suposta transição do modo de produção capitalista para uma “sociedade gerencial”. Essa doutrina ou teoria não é nova. Surgida a partir de uma série de desenvolvimentos na transição entre os séculos XIX e XX, ganhou fôlego com Bruno Rizzi e James Burnham nas décadas de 1930 e 1940, sendo o segundo autor uma fonte primária de grande difusão a partir do livro A Revolução Gerencial. Um segundo desenvolvimento teve impulso com J.K. Galbraith a partir dos anos de 1960, obtendo considerável difusão, inclusive no Brasil, por mediação de intelectuais como Bresser Pereira. Nas últimas décadas, autores como Gérard Duménil e Dominique Lévy surgiram como portavozes internacionais de uma renovada abordagem, supostamente de matriz marxista, tomando tais gestores como classe social, culminando na obra mais recente denominada Capitalismo Gerencial. Ao delimitar a análise aos materiais e J. Burnham e G. Duménil e D. Lévy, o estudo realizado pode ser considerado como um exercício de determinação social do pensamento segundo a tradição marxista. O estudo se baseou, principalmente, nos fundamentos da ontologia do ser social de G. Lukács. Nessa direção, delimitou-se a gênese e a função dessa teoria dos gestores como classe social, operacionalizando também uma análise imanente baseada nos textos escolhidos. Assim, foi possível identificar, apesar das diferenças, uma linha de continuidade da apologia indireta ao capitalismo de A Revolução Gerencial de J. Burnham a Capitalismo Gerencial de G. Duménil e D. Lévy. Nesse estudo, a teoria dos gestores se mostrou como uma variante da ideologia da terceira via, isto é, de negação superficial e de afirmação essencial do modo de produção capitalista em que se sustenta haver uma transição para uma nova sociedade cujos pilares, entretanto, permanecem ancorados nos princípios da produção de mercadorias para o lucro privado. Como variante, a teoria em questão apresenta sua particularidade propositiva, cujo núcleo é o amplo convencimento de que o modo de produção capitalista e suas mais essenciais contradições podem ser infinitamente administrados.
O “dois pra lá, dois pra cá” dos trajes de folguedo da cunhã-poranga do Boi Caprichoso

O Brasil é um país culturalmente plural em termos étnicos e religiosos, o que fomentou manifestações folclóricas como o Boi-Bumbá, que é a celebração das identidades culturais das sociedades interioranas, ribeirinhas e pastoris brasileiras. Em Parintins, no Amazonas, tanto o Boi Caprichoso quanto o Boi Garantido são “bois de promessa”, que não apenas revivem a tradição festiva em percorrer as ruas da cidade em uma espécie de procissão a luz de velas e candeeiros, entoando antigas toadas e procurando o calor das fogueiras de São João; mas que saíram das vielas e tablados de madeira para a arena, espetacularizando a história e a vivência poética dos povos amazônicos. Ao partir do prisma do Boi enquanto espetáculo, meu objetivo é expor as escritas visuais, que carregam em si discursos, presentes nos trajes de folguedo da personagem Cunhã-Poranga do Boi-Bumbá Caprichoso, que foram apresentados durante o Festival Folclórico de Parintins de 2019. Pretendo revelar como esses trajes femininos movimentam-se no “dois pra lá, dois pra cá”, que é o passo tradicional do Boi-Bumbá. Em outras palavras, busco evidenciar que, mesmo diante de uma postura de iminente e eminente emancipação feminina perante o olhar estereotipado do homem, a Cunhã-Poranga carrega a herança de um passado colonial, opressor e patriarcal. Acredito que este trabalho possa propor um novo olhar sobre as indumentárias de Boi-Bumbá, acrescentando assim uma visão crítica pouco explorada acerca do vestir folclórico amazônico no que tange a sua importância cultural, estética, histórica e social.

O projeto modernista em Cataguases apresenta peculiaridades significativas na formação da paisagem cultural e na construção identitária da população. Reflexo do desenvolvimento econômico e cultural propiciado pela industrialização, o projeto seguiu as mesmas bases modernistas advindas do Rio de Janeiro. Ao encomendar o projeto de sua residência e de um colégio a Oscar Niemeyer, o industrial Francisco Inácio Peixoto tornou-se o principal mecenas e propositor da estética moderna, à frente de um grupo de intelectuais que viram no Modernismo a possibilidade de reconfigurar a paisagem local e o pensamento social cataguasense. O presente texto discorre: a) sobre o contexto sociocultural de Cataguases, referenciado a disputa política -e as reformas urbanas- entre as famílias Vieira Rezende e Peixoto; b) analisa a formação do mecenato de arquitetura moderna e sua influência na transformação do pensamento local, com base nas teorias de Howard Becker (1982), Maria Lucia Bueno (2005) e Pierre Bourdieu (1989); c) e por fim, apresenta um breve levantamento dos murais modernistas existentes na cidade, ressaltando suas características e seus elementos compositivos.

O objetivo foi estudar o perfil da população idosa com desenvolvimento de síndrome respiratória aguda grave devido à COVID-19 na Macrorregião de Saúde Leste de Minas Gerais. Pesquisa descritiva e retrospectiva com análise de dados acessados por meio do Sistema de Informação de Vigilância Epidemiológica da Gripe. Foram analisados os dados de 2419 notificações de síndrome respiratória aguda grave de indivíduos com idade igual ou superior a 60 anos, com diagnóstico de COVID-19, no período de abril/2020 a abril/2021. A população idosa foi caracterizada em relação à: características gerais; evolução clínica da COVID-19 e presença de condições clínicas preexistentes. Os dados foram analisados de forma descritiva e inferencial. A maioria dos idosos (73,1±0,2 anos) se declarou pardo (61,6%) e residente na zona urbana (88,7%). Em relação à evolução clínica, 98,8% foram internados, 33,7% necessitou de internação na unidade de terapia intensiva e 19,1% necessitou de suporte ventilatório invasivo. Em relação às condições clínicas preexistentes, 53,9% dos idosos apresentavam doenças cardiovasculares crônicas, 29,8% diabetes, 5,8% doenças respiratórias crônicas, 6,7% obesidade e 4,2% doença renal crônica. A evolução para óbito ocorreu para 46,5% e se associou de forma significante com a presença de diabetes (P=0,003) e com a maior faixa etária (P=0,000). Conclui-se que houve uma alta taxa de mortalidade dos idosos com desenvolvimento de síndrome respiratória aguda grave devido à COVID-19 e que a presença de diabetes e a maior faixa etária se associaram com esse desfecho.
Eficiência de retentores utilizados para restauração de dentes tratados endodonticamente e sua obtenção por meio do escaneamento intraoral. Uma revisão sistemática e de escopo

Os dentes que recebem tratamento endodôntico na maioria das vezes apresentam extensa destruição coronária, seja pelo acesso endodôntico, trauma, ou processo carioso entre outras, tornando um desafio sua reconstrução, devolvendo-lhe a função no sistema estomatognático. O objetivo dessa revisão sistemática e de escopo trabalho foi fornecer suporte a estudantes e profissionais da odontologia acerca da decisão de usar ou não retentores intrarradiculares em dentes com tratamento endodôntico (DTE) e em caso de indicação para o uso, como os novos sistemas CAD/CAM e scanners intra orais (IOS), podem fornecer retentores mais ajustados ao canal radicular, garantindo maior retenção longevidade a esses elementos. O uso de retentores intrarradiculares era visto como um reforço da estrutura dentária remanescente, com o passar do tempo e a publicação de ensaios clínicos randomizados, ficou provado que eles fornecem somente suporte e retenção ao material restaurador, mas não garantem reforço à estrutura dentária. Ao contrário, podem ser responsáveis por falhas, como deslocamento, descimentação e até mesmo fraturas irreparáveis com consequente perda do elemento dental. A opção pelo não uso de retentores intrarradiculares deve se basear em uma avaliação clínica criteriosa da estrutura coronal remanescente e a área de adesividade para o material restaurador. O uso dos IOSs para confecção de retentores intrarradiculares ainda não está consolidado, uma vez que os aparelhos disponíveis diferem muito em qualidade de digitalização, técnica de escaneamento, facilidade de manuseio, formato da ponteira entre outras. Essas características podem influenciar a precisão dos IOSs, e sua capacidade de leitura no ambiente intra oral. O primeiro estudo in vitro sobre digitalização de conduto radicular foi somente em 2019, antes disso eram utilizadas técnicas que combinavam scanner de laboratório para digitalização da moldagem com digitalização de um pino de fibra dentro do conduto, com IOS, para fabricação de núcleos de preenchimento fresados que garantiam uma melhor adaptação marginal e consequente menos risco de descimentação. Portanto é possível concluir que os IOSs ainda têm muito a evoluir na digitalização de condutos radiculares, o que poderá propiciar melhores possibilidades para reconstrução de DTE com extensa destruição. A tecnologia dos sistemas adesivos também tende a evoluir constantemente e quando a opção for de reabilitação de DTE sem o uso de retentores intrarradiculares, esses novos sistemas restauradores poderão garantir mais resistência à fratura dos DTE e possibilidades de redução de falhas irreparáveis ou irreparáveis.
