Introdução: A ultrassonografia à beira do leito realizada por não especialista em imagem tem mostrado ser uma ferramenta útil na avaliação diagnóstica e realização de procedimentos invasivos. Diversas situações clínicas favorecem manifestações de instabilidade hemodinâmica, principalmente, nas unidades de terapia intensiva. Neste sentido, unidades pediátricas têm utilizado ecocardiografia funcional, muitas vezes, antes do exame realizado por um ecocardiografista. Objetivo: Avaliar a acurácia da ecocardiografia realizada por pediatra comparativamente à realizada por ecocardiografista em pacientes de uma unidade neonatal e pediátrica de tratamento intensivo. Material e Métodos: Análise retrospectiva dos prontuários de pacientes pediátricos de zero dia a 14 anos, internados na unidade de terapia intensiva, com indicação clínica para avaliação da existência de alterações anatômicas por ecocardiografia compreensiva e que também foram avaliados através da ecocardiografia funcional por pediatra. Resultados: Um total de 89 casos foram analisados com admissão variando de zero dia a 14 anos, sendo 55 do sexo masculino e 34 do sexo feminino. A sensibilidade e especificidade, respectivamente, da ecocardiografia funcional pelo pediatra comparado à ecocardiografia compreensiva feita pelo cardiologista relativamente às alterações encontradas foram: 80% e 96,2% para persistência do canal arterial; 88,4% e 98,4% para cardiopatia congênita acianótica; 77,7% e 98,7% para cardiopatia congênita cianótica e/ou críticas; 83,3% e 98,8% para miocardiopatia hipertrófica; 100% e 100% para derrame pericárdico; e 76,2% e 96,2% para hipertensão pulmonar persistente neonatal. Conclusões:Os resultados demonstram boa acurácia do pediatra realizando a ecocardiografia funcional quando comparado com exame realizado pelo cardiologista (ecocardiografia compreensiva), o que não reduz a importância e obrigatoriedade da análise do especialista. A incorporação da ecocardiografia funcional na avaliação rotineira pediátrica permite expandir e melhorar o exame físico pelo pediatra.

Objetivo: Analisar a composição proximal de bolo de baunilha sem glúten, com a substituição parcial da farinha de arroz pela farinha da borra de açaí, com a finalidade de aproveitar o resíduo que foi gerado no processamento do fruto, além de observar as possíveis alterações no bolo. Métodos: Os bolos foram elaborados com variadas concentrações da farinha da borra de açaí (0%, 5% e 20%) e analisados quanto ao teor de umidade, cinzas, lipídios, proteínas e carboidratos totais, além do valor calórico de cada amostra. Resultados: Após avaliar a composição proximal, observou-se que a presença da farinha da borra de açaí no bolo de baunilha sem glúten, nas proporções de 0%, 5% e 20%, modificou os teores de lipídios (5,14%, 4,91% e 5,51%), proteínas (3,26%, 3,27% e 3,01%) e carboidratos totais (67,63%, 68,01% e 64,90%) respectivamente. Ao analisar o valor calórico foi possível perceber diferentes médias entre as concentrações nos bolos, sendo o controle, 5% e 20% com valores de 329,38 Kcal, 315,40 Kcal e 321,79 Kcal respectivamente. Esses resultados destacam a diversidade nos componentes nutricionais e como a incorporação de uma matéria prima fora dos padrões pode influenciar aspectos como textura (umidade) e valor calórico, sendo relevante considerar tais variações ao formular produtos, conforme as necessidades dietéticas e preferências dos consumidores. Conclusão: A utilização da borra do açaí processada e convertida em farinha, modificou as características químicas do bolo sem glúten e pode ser uma alternativa para contribuir para uma gestão ambiental responsável do resíduo da agroindústria do açaí.
PROCESSO ADMINISTRATIVO DISCIPLINAR, DISCRICIONARIEDADE E CONTROLE JUDICIAL DO MÉRITO: UMA ANÁLISE DE CASOS DO TRIBUNAL DE JUSTIÇA DO RIO GRANDE DO SUL
Authors: FILIPIN Vinícius , Moreira Guacira
Published: March 2024

O artigo visa analisar a discricionariedade inerente ao processo administrativo disciplinar, especialmente quando resulta em demissão e é posteriormente sujeito a controle judicial. Inicialmente, aborda-se a discricionariedade administrativa e o processo disciplinar, destacando a importância dos princípios que orientam o controle da Administração Pública. Examina-se então o alcance do princípio da inafastabilidade do controle jurisdicional, considerando que muitas decisões judiciais parecem estar limitadas em termos argumentativos devido ao respeito aos limites da separação dos poderes. No entanto, há divergências na doutrina e jurisprudência quanto à atuação do controle judicial, especialmente em relação aos atos discricionários, dada a sua subjetividade. Para elucidar o tema, recorre-se à revisão doutrinária e análise jurisprudencial. Conclui-se que não há critérios objetivos na abordagem do Poder Judiciário gaúcho ao controlar processos administrativos disciplinares, oscilando entre uma análise detalhada do mérito e um foco no devido processo legal, contraditório e ampla defesa, em consonância com a separação dos poderes. Destaca-se que, em decisões sobre abandono de cargo, que envolvem um processo administrativo especial, o Poder Judiciário, apesar de iniciar a fundamentação respeitando os limites do controle, acaba por adentrar no mérito ao investigar as razões desse abandono.

Authors: Moreira Carlos , Urbano Eduardo Stehling
Published: March 2024

A osteomielite é uma doença infecciosa que acomete o tecido ósseo, tendo grande relevância da pesquisa e ciência diante de sua alta taxa de morbimortalidade. Certos estudos vêm sugerindo que a via hematógena pode levar infecções distantes até os ossos maxilares, porém a principal origem microbiológica das osteomielites são advindas das infecções odontogênicas, principalmente as endodônticas, quando o processo de propagação das infecções alcança a região óssea. Nesse sentido, o complexo maxilomandibular se torna o principal alvo dessas inflamações infecciosas que podem corroborar para a perda da maxila e/ou mandíbula e, além disso, contribuir para propagação da infecção para áreas distantes do local de origem. Dessa forma, o objetivo deste trabalho é alcançar o diagnóstico e a terapêutica da osteomielite a fim de oferecer um melhor prognóstico e assertividade terapêutica. Foram realizadas buscas nas principais bases de dados: Pubmed e Scielo; selecionados 20 artigos que esclarecem dados e informações a respeito do diagnóstico e a terapêutica disponível para osteomielite. Concluiu-se que, os exames de imagem associados à história pregressa levam a um correto diagnóstico e, o conhecimento a respeito dos principais microrganismos envolvidos, coleta de espécime e realização de antibiograma, instituição de antibioticoterapia parenteral específica e a realização de debridamento, são etapas a serem consideradas durante o tratamento da osteomielite para alcance de melhores resultados.

The study of float wave formation for the usage as heavy-duty catamaran bulbs
Authors: Cheban Egor Yu. , Kozhevnikov Artur I.
Published: March 2024

The large cargo catamaran ferries can increase speed freight transportation on inland waterways. However, an increase of vessel's speed entails the growth in the heights of ship waves when the ship, which in turn adversely affects both the hydrodynamic characteristics of the ship itself, enhances wave impacts on the catamaran bridge and the ecological state of water bodies. According some scientific articles one way to reduce wave resistance of large catamarans may be deployment а a float-bulb between it hulls. Ship's wave and wave resistance depend on the shape of the float-bulb, so it is advisable to study the parameters of the waves formed first on the bulb in free flow, and then together with the catamaran. In this paper presents analytical equations for the resistance of the "float-catamaran complex", as well as formulas that also allow one to calculate the main parameters of the float-bulb. The results of numerical simulation are presented for the three ellipsoid's length: 29,2m (Fr=0,414-0,691), 14,6m (Fr=0,585-0,978) and 7,3m (Fr=0,827-1,383), ball d=1,76m (Fr=1,685-2,816). The characteristics of the generated ship waves is determined. Conclusions about the feasibility of modifying the float-bulb shape for heavy catamarans is given.

Published: March 2024

One of the problems of operational and economic feasibility is determining the economic efficiency of a new ships. The complexity of the problem increases for shipis od river and sea-river class due to the high variability of navigation conditions, which significantly affect efficiency indicators. The purpose of the article is to study the mutual influence of the technical indicators of sea-river cargo ship and the economic indicators of its operation, taking into account the navigation conditions on specific sections of waterways. Various technical indicators are considered and it is shown that the most comprehensive indicator is the specific fuel consumption per ton-kilometer. The influence of the error of forecast technical indicators on economic indicators was assessed. It is shown that the optimality of economic indicators depends on the characteristics of the waterway so that a vessel that is optimal on one waterway may not be optimal on another. It has also been established that optimal technical parameters do not always agree with optimal economic ones.
Application of Reliability Centred Maintenance in Improving Aircraft Availability with Preventive Maintenance Intervention
Authors: Om Prakash Bohrey  , Ashwin Sharadrao Chatpalliwar
Published: March 2024

Aircraft are intricate flying machines equipped with advanced technologies and state-of-the-art information and communication systems. Maintaining these aircraft to ensure maximum availability and minimal downtime is a critical and challenging task. Therefore, aircraft maintenance, repair, and servicing are of utmost importance. This research work aims to develop a methodology for reliability centred maintenance (RCM) to enhance aircraft availability. An RCM approach with the Multi attribute decision making (MADM) technique for assigning criticality of systems was implemented to improve aircraft availability. Failure mode and effects analysis (FMECA) was utilized for the failure investigation in the aircraft systems. However, instead of the Risk priority number (RPN) due to its inherent flaws, the Analytical hierarchy process (AHP) was utilized to evaluate the criticality of systems. The remedial measures to minimize the failure frequency and downtime were proposed. The improvement in availability, post implementation of proposed preventive maintenance was validated with positive results. An improvement of approximately 6.62% in availability and a reduction of about 15.71% in the total downtime was observed on the implementation of proposed preventive measures. The availability analysis was carried out for aircraft systems; however, the model could also be used for other repairable systems following a similar maintenance philosophy.

Intelligent routing protocols for IoV have also been made possible by the convergence of IoT and machine learning algorithm. In order to make informed routing decisions, these intelligent routing protocols examine data gathered from IoT devices like vehicle sensors and traffic monitoring systems using machine learning algorithms. Moreover, as the number of vehicles increases and road networks become more complex, traditional routing protocols for ad hoc networks are being replaced by more advanced and efficient protocols. The purpose of this study is to concentrate on these unique qualities of IoVs network scenario. A combined routing method has been developed to construct periodic connectivity and find routes on-demand in order to save route data as graphs. The simulation's findings show that GreedLea routing protocol outperforms GPSR and AODV routing protocols in terms of delay and packet delivery ratio (PDR). The results demonstrate that the average AODV latency is significantly higher when there are fewer vehicles on the network. This is due to the fact that connections are frequently lost at higher speeds and lower densities, and re-establishing new channels takes a lot of time. As the number of vehicles rises, efficiency improves and the wait gets shorter. The average latency, yet, keeps increasing as vehicle density increases due to the additional overheads related with routing.

This study aims to examine the improvement of interpersonal skills through the application of active learning in the teaching and learning of art education. The approach used is the theatre-play approach. Theatre games are used as a fresh and appropriate approach to learning art education subjects through various types of games that are applied with various theatre techniques, including improvisation, role playing, physical exercise, and voice acting. The subject of art education is a theoretical and practical one that requires high focus during learning. Therefore, theatre games are applied to encourage active learning and prevent students from getting bored when learning is conducted online. Students play, act, improvise, and sing while learning. This qualitative study involved eight Form 5 students at the Malaysian Art School using observation and interview methods. The study applies social learning theory and constructivist learning theory. The data was thematically analysed using Nvivo software. Findings found that active learning takes place in learning through the application of a theatre game approach and highlights the interpersonal skills of students. Two-way communication occurs in every activity because the activity is carried out in groups. Studies on the learning of art subjects that apply this active learning through theatre games are believed to promote confidence and stimulate students to improve their interpersonal skills without realising it.

Published: March 2024

With the growing number of gravitational wave (GW) detections and the advent of large galaxy redshift surveys, a new era in cosmology is emerging. This study explores the synergies between GWs and galaxy surveys to jointly constrain cosmological and GW population parameters. We introduce CHIMERA, a novel code for GW cosmology combining information from the population properties of compact binary mergers and galaxy catalogs. We study constraints for scenarios representative of the LIGO-Virgo-KAGRA O4 and O5 observing runs, assuming to have a complete catalog of potential host galaxies with either spectroscopic or photometric redshift measurements. We find that a percent-level measurement of H
0 could be achieved with the best 100 binary black holes (BBHs) in O5 using a spectroscopic galaxy catalog. In this case, the intrinsic correlation that exists between H
0 and the BBH population mass scales is broken. Instead, by using a photometric catalog the accuracy is degraded up to a factor of ∼9, leaving a significant correlation between H
0 and the mass scales that must be carefully modeled to avoid bias. Interestingly, we find that using spectroscopic redshift measurements in the O4 configuration yields a better constraint on H
0 compared to the O5 configuration with photometric measurements. In view of the wealth of GW data that will be available in the future, we argue the importance of obtaining spectroscopic galaxy catalogs to maximize the scientific return of GW cosmology.

Published: March 2024

PDS 70 hosts two massive, still-accreting planets and the inclined orientation of its protoplanetary disk presents a unique opportunity to directly probe the vertical gas structure of a planet-hosting disk. Here, we use high-spatial-resolution (≈0.″1; 10 au) observations in a set of CO isotopologue lines and HCO+
J = 4−3 to map the full 2D (r, z) disk structure from the disk atmosphere, as traced by 12CO, to closer to the midplane, as probed by less abundant isotopologues and HCO+. In the PDS 70 disk, 12CO traces a height of z/r ≈ 0.3, 13CO is found at z/r ≈ 0.1, and C18O originates at, or near, the midplane. The HCO+ surface arises from z/r ≈ 0.2 and is one of the few non-CO emission surfaces constrained with high-fidelity in disks to date. In the 12CO J = 3−2 line, we resolve a vertical dip and steep rise in height at the cavity wall, making PDS 70 the first transition disk where this effect is directly seen in line-emitting heights. In the outer disk, the CO emission heights of PDS 70 appear typical for its stellar mass and disk size and are not substantially altered by the two inner embedded planets. By combining CO isotopologue and HCO+ lines, we derive the 2D gas temperature structure and estimate a midplane CO snowline of ≈ 56–85 au. This implies that both PDS 70b and 70c are located interior to the CO snowline and are likely accreting gas with a high C/O ratio of ≈ 1.0, which provides context for future planetary atmospheric measurements from, e.g., JWST, and for properly modeling their formation histories.

The launches of Parker Solar Probe (Parker) and Solar Orbiter (SolO) are enabling a new era of solar wind studies that track the solar wind from its origin at the photosphere, through the corona, to multiple vantage points in the inner heliosphere. A key ingredient for these models is the input photospheric magnetic field map that provides the boundary condition for the coronal portion of many heliospheric models. In this paper, we perform steady-state, data-driven magnetohydrodynamic (MHD) simulations of the solar wind during Carrington rotation 2258 with the Grid GAMERA model. We use the ADAPT and AFT flux transport models and quantitatively assess how well each model matches in situ measurements from Parker, SolO, and Earth. We find that both models reproduce the magnetic field components at Parker quantitatively well. At SolO and Earth, the magnetic field is reproduced relatively well, though not as well as at Parker, and the density is reproduced extremely poorly. The velocity is overpredicted at Parker, but not at SolO or Earth, hinting that the Wang–Sheeley–Arge (WSA) relation, fine-tuned for Earth, misses the deceleration of the solar wind near the Sun. We conclude that AFT performs quantitatively similarly to ADAPT in all cases, and that both models are comparable to a purely WSA heliospheric treatment with no MHD component. Finally, we trace field lines from SolO back to an active region outflow that was observed by Hinode/EIS, and which shows evidence of elevated charge state ratios.

Contribution of γ-Ray Burst Afterglow Emissions to the Isotropic Diffuse γ-Ray Background

Published: March 2024

The isotropic diffuse γ-ray background (IGRB) serves as a fundamental probe of the evolution of the extreme Universe. Although various astrophysical sources have been proposed as potential contributors to the IGRB, the dominant population is still under debate. γ-ray bursts (GRBs) are among candidate contributors of IGRB, although they are not as frequently discussed as blazars or starburst galaxies. Recent observations of TeV emission from GRB afterglows have provided fresh insights into this subject. This work aims to investigate the potential contribution of GRB afterglows to the IGRB under the standard afterglow model. We carefully examine the influence of each microphysical parameter of the afterglow model on this contribution, with a particular emphasis on the significant role played by the initial kinematic energy. To determine the energy and quantify the contribution of GRB afterglow to IGRBs, we utilize the observed GRB afterglow energy emissions from the Swift X-ray Telescope and Fermi Large Area Telescope instruments. Our calculations, considering the synchrotron self-Compton emission, suggest that GRB afterglows make up less than 10% of the IGRBs. To enhance the precision of our findings, it is crucial to further constrain these parameters by conducting additional ground-based observations of GRB afterglows.

The millisecond pulsar J1713+0747 underwent a sudden and significant pulse shape change between 2021 April 16 and 17 (MJDs 59320 and 59321). Subsequently, the pulse shape gradually recovered over the course of several months. We report the results of continued multifrequency radio observations of the pulsar made using the Canadian Hydrogen Intensity Mapping Experiment and the 100 m Green Bank Telescope in a 3 yr period encompassing the shape change event, between 2020 February and 2023 February. As of 2023 February, the pulse shape had returned to a state similar to that seen before the event, but with measurable changes remaining. The amplitude of the shape change and the accompanying time-of-arrival residuals display a strong nonmonotonic dependence on radio frequency, demonstrating that the event is neither a glitch (the effects of which should be independent of radio frequency, ν) nor a change in dispersion measure alone (which would produce a delay proportional to ν
−2). However, it does bear some resemblance to the two previous “chromatic timing events” observed in J1713+0747, as well as to a similar event observed in PSR J1643−1224 in 2015.
Velocity Dispersions of Quiescent Galaxies in IllustrisTNG
Authors: Sohn Jubee , Geller Margaret J. , Borrow Josh , Vogelsberger Mark
Published: March 2024

We examine the central stellar velocity dispersion of subhalos based on IllustrisTNG cosmological hydrodynamic simulations. The central velocity dispersion is a fundamental observable that links galaxies with their dark matter subhalos. We carefully explore simulated stellar velocity dispersions derived with different definitions to assess possible systematics. We explore the impact of variation in the identification of member stellar particles, the viewing axes, the velocity dispersion computation technique, and simulation resolution. None of these issues impact the velocity dispersion significantly; any systematic uncertainties are smaller than the random error. We examine the stellar mass–velocity dispersion relation as an observational test of the simulations. At fixed stellar mass, the observed velocity dispersions significantly exceed the simulation results. This discrepancy is an interesting benchmark for the IllustrisTNG simulations because the simulations are not explicitly tuned to match this relation. We demonstrate that the stellar velocity dispersion provides measures of the dark matter velocity dispersion and the dark matter subhalo mass.
A Measurement of the Assembly of Milky Way Analogs at Redshifts 0.5 < z < 2 with Resolved Stellar Mass and Star Formation Rate Profiles

Published: March 2024

The resolved mass assembly of Milky Way–mass galaxies has been previously studied in simulations, the local Universe, and at higher redshifts using infrared (IR) light profiles. To better characterize the mass assembly of Milky Way analogs (MWAs), as well as their changes in star formation rate (SFR) and color gradients, we construct resolved stellar mass and SFR maps of MWA progenitors selected with abundance matching techniques up to z ∼2 using deep, multiwavelength imaging data from the Hubble Frontier Fields. Our results using stellar mass profiles agree well with previous studies that utilize IR light profiles, showing that the inner 2 kpc of the galaxies and the regions beyond 2 kpc exhibit similar rates of stellar mass growth. This indicates the progenitors of MWAs from z ∼ 2 to the present do not preferentially grow their bulges or their disks. The evolution of the SFR profiles indicates a greater decrease in SFR density in the inner regions versus the outer regions. Sérsic parameters indicate modest growth in the central regions at lower redshifts, perhaps indicating slight bulge growth. However, the Sérsic index does not rise above n ∼ 2 until z < 0.5, meaning these galaxies are still disk-dominated systems. We find that the half-mass radii of the MWA progenitors increase between 1.5 < z < 2, but remain constant at later epochs (z < 1.5). This implies mild bulge growth since z ∼ 2 in MWA progenitors, in line with previous MWA mass assembly studies.

We present the results of a spectral analysis using simultaneous multifrequency (22, 43, 86, and 129 GHz) very long baseline interferometry (VLBI) observations of the Korean VLBI Network on BL Lac object, Markarian 421. The data we used were obtained from 2013 January to 2018 June. The light curves showed several flux enhancements with global decreases. To separate the variable and quiescent components in the multifrequency light curves for milliarcsecond-scale emission regions, we assumed that the quiescent radiation comes from the emission regions radiating constant optically thin synchrotron emissions (i.e., a minimum flux density with an optically thin spectral index). The quiescent spectrum determined from the multifrequency light curves was subtracted from the total CLEAN flux density, yielding a variable component in the flux that produces the time-dependent spectrum. We found that the observed spectra were flat at 22–43 GHz, and relatively steep at 43–86 GHz, whereas the quiescent-corrected spectra are sometimes quite different from the observed spectra (e.g., sometimes inverted at 22–43 GHz). The quiescent-corrected spectral indices were much more variable than the observed spectral indices. This spectral investigation implies that the quiescent-spectrum correction can significantly affect the multifrequency spectral index of variable compact radio sources such as blazars. Therefore, the synchrotron self-absorption B-field strength (B
SSA) can be significantly affected because B
SSA is proportional to the fifth power of turnover frequency.

Extracting precise stellar labels is crucial for large spectroscopic surveys like the Sloan Digital Sky Survey (SDSS) and APOGEE. In this paper, we report the newest implementation of StellarGAN, a data-driven method based on generative adversarial networks (GANs). Using 1D operators like convolution, the 2D GAN is modified into StellarGAN. This allows it to learn the relevant features of 1D stellar spectra without needing labels for specific stellar types. We test the performance of StellarGAN on different stellar spectra trained on SDSS and APOGEE data sets. Our result reveals that StellarGAN attains the highest overall F1-score on SDSS data sets (F1-score = 0.82, 0.77, 0.74, 0.53, 0.51, 0.61, and 0.55, for O-type, B-type, A-type, F-type, G-type, K-type, and M-type stars) when the signal-to-noise ratio (S/N) is low (90% of the spectra have an S/N < 50), with 1% of labeled spectra used for training. Using 50% of the labeled spectral data for training, StellarGAN consistently demonstrates performance that surpasses or is comparable to that of other data-driven models, as evidenced by the F1-scores of 0.92, 0.77, 0.77, 0.84, 0.84, 0.80, and 0.67. In the case of APOGEE (90% of the spectra have an S/N < 500), our method is also superior regarding its comprehensive performance (F1-score = 0.53, 0.60, 0.56, 0.56, and 0.78 for A-type, F-type, G-type, K-type, and M-type stars) with 1% of labeled spectra for training, manifesting its learning ability out of a limited number of labeled spectra. Our proposed method is also applicable to other types of data that need to be classified (such as gravitational-wave signals, light curves, etc.).

Within the framework of “Proryv” project a radiation-equivalent approach to radioactive waste management is being envisioned with U and Pu recycling and MA transmutation. Successful industry-wide implementation of the design approaches should be planned in order to avoid considerable financial and radiological encumbrances caused by the NFC final stage for two-component nuclear power system (NPS) under formation on the basis of thermal and fast reactors. In order to ensure a successful industry-wide implementation of the approaches being developed, the back-end of the NFC should not constitute considerable a financial and radiological burden for the emerging two-component nuclear power system (NPS).

This article addresses the problems concerning justification of radiological and technical-and-economic feasibility of MA partitioning and subsequent transmutation in FNR. The extent of MA accumulation as a result of TNR SNF reprocessing confirms the need for the introduction of MA partitioning technologies not only at all reprocessing plants planned for commissioning, but also at the plants now in operation. Based on available data, the study has shown that the implementation of the closed NFC with FNR contributes to significant reduction in the cost of disposal of radwaste compared to the scenario based exclusively on the development of VVER and open fuel cycle technologies. Recycling plutonium in fast reactors should be implemented in conjunction with MA to address environmental, non-proliferation and economic concerns of the back-end of advanced NFC. Within the scale of the future nuclear power system in Russia, an option such as this can only be realized on the basis of developing a FNR fleet.
Self-rated health of the older population in Estonia and Russia: the impact of ethnic, cross-country differences and age at migration

Within the framework of the life trajectory paradigm, factors of poor health in older age may include ethnicity, as well as migration history of an individual. Estonia, with a large share of the Russian population, is a good example to analyze the impact of migration and changes in the ethnic environment on health throughout the life course. The purpose of the study is to assess differences in self–rated health of the older population (50+) living in Estonia and Russia, and identify reasons for these differences. The empirical basis of the study was data of the SHARE survey conducted in Estonia in 2010-2011 and the SAGE survey conducted in Russia in 2007-2010. The sample includes urban population aged 50+ in private households: 2,655 Estonians living in Estonia, 1,478 Russians living in Estonia, and 2,446 Russians living in Russia. The tested ordinal regression models show that the native-born in Estonia have a 39% higher chance of rating their health as good compared to Russians in Estonia, which is associated with differences in educational level in the population aged 50-64, while in the population aged 65+ it is associated with differences in living standards between the native-born and immigrants of the first and subsequent generations. At the same time, Russians from Russia are 70% (population aged 50-64) or 60% (population 65+) less likely to rate their health as good, which is related to the lifestyle and loneliness. Russians aged 65+ in Estonia who moved to the country at the age of 25+ have the same chances. The study negatives the healthy migrant effect identified in young immigrants, and also indicates health behavior and poor quality of social connections as possible reasons for poor health of the older Russian residents.
Sociodemographic and behavioral factors of pre-obesity and obesity among adult Russians
Authors: Churilova Elena , Rodina Olga
Published: March 2024

Based on data from the 2021 Sample Population Health Survey, the paper assesses the prevalence and socio-demographic and behavioral risk factors of pre-obesity and obesity among the adult population of Russia. A standard approach for epidemiological studies was used: body weight was assessed using the Body Mass Index (BMI). The influence of risk factors was determined by logistic regressions. It was revealed that the average BMI value among men is 26.9 kg/m2 and among women - 26.8 kg/m2. At the age of 18 and over, 67.2% of men and 57.9% of women are overweight, and 19.5% of men and 24.9% of women are obese. The prevalence of overweight and obesity increases with age but decreases after age 75. There is a relationship between pre-obesity and eating habits of men and women: frequent consumption of foods high in salt, sausage and meat products, and sweets. Obesity in men is associated with the same factors as pre-obesity. Among women, the consumption of sweets and smoked meat products ceases to have a significant effect on the likelihood of obesity. A comparison of our results with the results of previous studies makes it possible to conclude that there is no significant change in the prevalence of overweight and obesity among Russians. A sustainable influence of behavioral and eating habits allows us to conclude that it is necessary to conduct a state awareness campaign about components of a healthy lifestyle and develop measures to increase commitment to physical education, sports, and healthy eating among the population.
La répression du dopage
Authors: Thierry Jean-Baptiste
Published: March 2024

Le dopage est une pratique qui porte atteinte à la santé du sportif et à l'équité des compétitions sportives. Le retentissement de certains scandales a conduit les autorités à mettre en place un droit répressif, pénal et administratif, particulièrement sévère. L'ampleur de la répression du dopage pose toutefois des difficultés au regard des droits fondamentaux des sportifs et de son efficacité même.

Published: March 2024

Dans le cadre d'une formation à l'ENM de Bordeaux, les magistrats du pôle humanités judiciaires ont réalisé une enquête auprès des auditeurs de justice des promotions 2020 et 2021 afin de recueillir leurs perceptions à l'égard des « biais de jugement ». 549 auditeurs ont répondu au questionnaire diffusé. L'analyse de leurs réponses permet de voir comment ils définissent la notion de « biais », s'ils pensent avoir eux-mêmes déjà été confrontés à des décisions biaisées et les solutions qu'ils envisagent pour limiter cette influence. La réflexion interdisciplinaire menée sur les résultats obtenus offre de nouvelles pistes d'actions de formation pour l'ENM.
Enfants sourds avec troubles associés : intérêt de l’évaluation des fonctions de captation et de traitement de l’information visuelle
Authors: Lasserre Elisabeth , Voynet Anne
Published: March 2024

Parmi les troubles susceptibles d’être associés à la surdité, nous retrouvons fréquemment des troubles du regard et de la vision, du contrôle oculomoteur, de l’attention visuo-spatiale, de la reconnaissance visuelle des objets et des visages. Nos hypothèses concernant les répercussions de ces troubles sur le développement de la communication d’un enfant sourd et de sa relation à l’autre ainsi que sur son accès au langage seront évoquées à travers la présentation de plusieurs vignettes cliniques. Les remédiations proposées visent à apporter à l’enfant sourd présentant de tels troubles des repères visuels stables et permanents afin de faciliter son accès au sens.
Pédopsychiatrie et surdité
Authors: Delaroche Jean-Michel
Published: March 2024

Dans notre pays, les enfants sourds n’ont pas accès aux soins de santé mentale, notamment dans le dispositif de la psychiatrie de secteur. Les prises en charge nécessitent en effet une formation particulière (langue des signes française, notamment) et une connaissance approfondie des effets de la surdité que tous les services ne peuvent acquérir. La clinique des enfants sourds est riche et complexe, elle demande une approche plurilinguistique et transculturelle.

Expérience de la communication multimodale
Authors: Henry Sandra , Pleah Cécile
Published: March 2024

Parole, gestes, intonations, expressions… La communication s’articule autour de nombreux facteurs qui, ensemble, apportent une information précieuse à la compréhension du langage oral. Des craintes parentales relatives à la surdité, le profil de certains enfants, peuvent entraver cette communication. Il s’avère tout à fait profitable d’étayer les intentions langagières au moyen de divers modes alternatifs de communication, tout en tenant compte des spécificités et des possibilités propres à chaque famille.
L’enfant élevé dans des cubes. L’ivresse et le législateur royal de Platon à Roger Caillois
Authors: Douailler Stéphane
Published: March 2024

L’œuvre de Roger Caillois se présente comme la longue exploration d’un art des passages et des cohérences aventureuses entre phénomènes. Elle consonne particulièrement par ce trait avec une double orientation du présent, qui d’un côté pousse les arts, les sciences, la philosophie, dans une invention d’appareillages de l’hétérogène, et d’un autre la vie sociale et culturelle dans un lien poétique et moral avec les lointains. Comparant au plus près certains textes de Caillois avec les Lois de Platon, le texte montre que cette perspective doit faire l’épreuve de se confronter aux réflexions de Roger Caillois sur le pouvoir et la politique, et à sa compréhension de la modernité démocratique.
