Published: December 2024

The purpose of this study is to investigate the relationship between parental psychological control, fear of failure, and competitive anxiety perceived by middle and high school Taekwondo players. For this purpose, data from 375 people were used in the final analysis. Data processing was performed using SPSS WIN Ver. The hypothesis was verified and analyzed using the 21.0 statistical program. The conclusions drawn through the above process are as follows. First, the psychological control of parents perceived by middle and high school Taekwondo players was found to be significant in their fear of failure. Second, the psychological control of parents perceived by middle and high school Taekwondo players was found to be significant for competitive anxiety. Third, the fear of failure perceived by middle and high school Taekwondo players was found to be significantly related to competitive anxiety. There is a risk that parental psychological control may reduce the player's ability and value. It is believed that parents need to seek ways to improve self-management and self-efficacy with an attitude of acceptance.

Authors:   Korean Society for Leisure Scie, Yeo Kyoung-Ah , Kwon Yeon-Taek
Published: December 2024

The purpose of this study is to provide basic information for revitalizing surfing through analysis of social awareness of surfing. This study collected data using Textome and conducted analysis using Textome, UCINET 6, and Netdraw. As a result of the study, Yangyang-gun was at the center of the expansion of the surfing base, and the main issues were formed into four groups: overseas surfing experience, Yangyang surfing experience, surfing experience in areas other than Yangyang, and surfing lesson experience. Through the results of this study, first, it was confirmed that Yangyang is a famous surfing spot, and second, Yangyang-gun needs to maintain a bottom-up regional development paradigm in order to continue its reputation as a surfing spot. Third, local governments that use surfing as a tourism resource need to benchmark Yangyang-gun and develop new tourism products that take regional characteristics into account. Fourth, it is necessary to prepare measures to improve accessibility in areas with low accessibility for young people, who are the main participants in surfing.

Authors:   Korean Society for Leisure Scie, Hwang Su-young , Choi In-Sik
Published: December 2024

This study investigates the relationships between self-management strategies, mental toughness, and perceived performance among golf players. Data were collected through surveys from 131 registered student athletes, amateurs, and professional players from the Korea Golf Association. To measure self-management, mental toughness, and perceived performance, the survey tools used in previous studies were modified and refined to align with the goals of this research. Validity and reliability were confirmed through confirmatory factor analysis. The results revealed that self-management significantly positively influenced both mental toughness and perceived performance. Furthermore, mental toughness mediated the relationship between self-management and perceived performance, with the mediation effect being statistically significant. This study demonstrates the impact of self-management strategies on actual performance outcomes in sports psychology and highlights the need for their integration into training and coaching programs. Additionally, it shows that improving self-management skills can contribute to overall performance and psychological stability. Future research should further explore the specific effects of self-management strategies across different sports disciplines and competitive levels.

Published: December 2024

BACKGROUND

Esophageal stricture ranks among the most significant complications following endoscopic submucosal dissection (ESD). Excessive fibrotic repair is a typical pathological feature leading to stenosis after ESD.

AIM

To examine the effectiveness and underlying mechanism of Kangfuxin solution (KFX) in mitigating excessive fibrotic repair of the esophagus post-ESD.

METHODS

Pigs received KFX at 0.74 mL/kg/d for 21 days after esophageal full circumferential ESD. Endoscopic examinations occurred on days 7 and 21 post-ESD. In vitro , recombinant transforming growth factor (TGF)-β1 (5 ng/mL) induced a fibrotic microenvironment in primary esophageal fibroblasts (pEsF). After 24 hours of KFX treatment (at 1.5%, 1%, and 0.5%), expression of α-smooth muscle actin-2 (ACTA2), fibronectin (FN), and type collagen I was assessed. Profibrotic signaling was analyzed, including TGF-β1, Smad2/3, and phosphor-smad2/3 (p-Smad2/3).

RESULTS

Compared to the Control group, the groups treated with KFX and prednisolone exhibited reduced esophageal stenosis, lower weight loss rates, and improved food tolerance 21 d after ESD. After treatment, Masson staining revealed thinner and less dense collagen fibers in the submucosal layer. Additionally, the expression of fibrotic effector molecules was notably inhibited. Mechanistically, KFX downregulated the transduction levels of fibrotic functional molecules such as TGF-β1, Smad2/3, and p-Smad2/3. In vitro , pEsF exposed to TGF-β1-induced fibrotic microenvironment displayed increased fibrotic activity, which was reversed by KFX treatment, leading to reduced activation of ACTA2, FN, and collagen I. The 1.5% KFX treatment group showed decreased expression of p-Smad 2/3 in TGF-β1-activated pEsF.

CONCLUSION

KFX showed promise as a therapeutic option for post-full circumferential esophageal ESD strictures, potentially by suppressing fibroblast fibrotic activity through modulation of the TGF-β1/Smads signaling pathway.

Authors:   North-Caucasus Federal University, Ter-Grigor’yants A. A. , Shelukhina E. A. ,   North-Caucasus Federal University
Published: December 2024

Introduction. In the current conditions of functioning of individual branches of the economy, it is important to timely monitor their achievement of established social and economic indicators reflecting the effectiveness of the regional state policy. The sectoral structure of the region is its distinctive characteristic, forming the basic potential for creating mechanisms for the most efficient use of available resources in new economic conditions. Analysis of structural shifts over time allows us to identify the so-called specialization sectors that form the largest share of the gross regional product and provide employment for the population, thereby ensuring an increase in the level of well-being of the population of the region.

Goal. Quantitative analysis of social efficiency indicators of the regional sectoral structure, reflecting the level of impact of adopted economic measures on meeting the needs of society for increased well-being.

Materials and methods. The study was conducted using statistical and comparative analysis tools, classification, and grouping, which allowed us to form a basis for assessing structural industry shifts in the region based on the obtained values of social efficiency indicators of the regional policy. The information basis of the study was provided by reviews and reports of Russian (Rosstat) statistical institutions, as well as open access materials of analytical companies.

Results and discussion. To assess structural shifts in the regional economy, the sectoral structure of the region was analyzed by types of economic activity. It was revealed that the sectoral specialization changed during the study period, which affected the economic and social indicators of the development of the region. The identified indicators of social efficiency of the sectoral structure of the regional economy were considered in their interconnection and interdependence, as they form a single social criterion for the purposes of the regional economic policy of Stavropol Krai.

Conclusion. The conducted analysis of the social efficiency indicators of the sectoral structure of the regional economy allowed us to conclude that there are structural shifts that have affected the level of well-being of the population of the region. Effective adaptation to changing conditions of the functioning of industries, taking into account the new specialization, will ensure a comprehensive, interconnected and balanced development of regional industries.

Published: December 2024

Introduction. The reference to the history of forming an independent Caucasian and Black Sea diocese is due to the study of the problem of the incorporation of the North Caucasus into the Russian Empire. In the absence of an extensive system of administrative control bodies and a protracted military conflict in the first half of the 19th century, the process of searching for a platform of national identity was underway, which allowed not only to reduce the level of escalation of the conflict, but also to incorporate the North Caucasus into the socio-cultural space of the Russian Empire.
Materials and Methods. The study is based on the principles of an interdisciplinary approach, which allowed us to consider the problem in its entirety, combine data obtained from different fields, look at the problem of the influence of the clergy and the Orthodox cultural tradition from different positions, expand and deepen the existing body of scientific knowledge on this issue. The method used made it possible to conduct modern historical research from the standpoint of historical anthropology. In addition, the work uses narrative, historicalgenetic, historicaltypological, retrospective and anthropological research methods. The research is based on materials from archival collections and review articles of the Caucasian (Stavropol) Diocesan Gazette. The analysis of the problems raised is reflected in the works of researchers of the history of the Cossacks V.A. Potto, F.A. Shcherbina, and the nature of colonization of the region G.N. Prozritelev. The organization of church administration and the personality of the first bishop Jeremiah (Solovyov) was analyzed in the study by I.K. Smolich.
Results. According to the results of the study, it can be concluded that, being in the minority in relation to the ascetics of Islam, Old Believers, sectarians inhabiting the region, the Orthodox population managed to create the basis for the spiritual unity of the population of the region. The traditions of Orthodox culture in the North Caucasus have become the basis of ethnocultural identity, acting as a historical and cultural landmark for a certain part of the population.

Remediating the ‘Golden Age’ of Library Music in a Digital Context
Authors: JOHNSTON NESSA , ROY ELODIE A.
Published: December 2024

Drawing from the concept of remediation (Bolter & Grusin, 1999), this article maps out the proto-digital and digital history of library music with a focus on music of the 1960s and 1970s, a period known as its ‘Golden Age’. The authors interrogate how recorded music libraries materially reinvented themselves – or were re-mediated – through the decades. The first part of this article surveys prevailing industrial practices and discourses of the 1960s and 1970s, arguing that library music firms embraced possibilities offered by digitisation from the outset, contrary to prevalent industry practice. The second part engages with ‘Golden Age’ library music’s online life and reinventions. By paying broader attention to its reception and transformation by fans, collectors, and creative practitioners, we resituate library music practices within a longer techno-cultural continuum from proto-digital to digital. We argue that the remediation approach helps theorise these myriad lives of library music across extended spatiotemporal eras. Remediation is not a linear reading of musical and technological history; rather, it acknowledges the synchronicities and porosities that exist between old and new by emphasising the moments of return and repetition central to the genesis of library music and to our affective experience of it.

We present X-ray spectroscopy of the SU UMa–type dwarf nova Z Chamaeleontis using the European Photon Imaging Camera and reflection grating spectrometer (RGS) instruments on board the XMM-Newton observatory. The quiescent system can be modeled by collisional equilibrium (CIE) or nonequilibrium plasma models, yielding a kT of 8.2–13.0 keV at a luminosity of (5.0–6.0) × 1030 erg s−1. The spectra yield better

using partially covering absorbers of cold and/or photoionized nature. The ionized absorber has an equivalent N
H = (3.4–5.9) × 1022 cm−2 and a log(ξ) = 3.5–3.7 with a (50–60)% covering fraction when the VNEI model (XSPEC) is used. The line diagnosis in quiescence shows no resonance lines, with only the forbidden lines of Ne, Mg, and Si detected. The H-like C, O, Ne, and Mg are detected. The strongest line is O viii, with (2.7–4.6) × 10−14 erg s−1 cm−2. The quiescent X-ray-emitting plasma is not collisional and not in ionization equilibrium, which is consistent with hot ADAF-like accretion flows. The line diagnosis in the outburst shows He-like O and Ne, with intercombination lines being the strongest, along with weaker resonance lines. This indicates the plasma is more collisional and denser, but not yet in CIE, revealing ionization timescales of (0.97–1.4) × 1011 s cm−3. The R ratios in the outburst yield electron densities of (7–90) × 1011 cm−3 and the G ratios yield electron temperatures of (2–3) × 106 K. The outburst luminosity is (1.4–2.5) × 1030 erg s−1. The flow is inhomogeneous in density. All detected lines are narrow, with widths limited by the resolution of RGS, yielding Keplerian rotational velocities <1000 km s−1. This is too low for boundary layers, consistent with the nature of ADAF-like hot flows.
A Thorough Search for Short-timescale Periodicity in Four Active Repeating Fast Radio Bursts
Authors: Du Chen , Huang Yong-Feng , Zhang Zhi-Bin , Rodin Alexander , Fedorova Viktoriya , Kurban Abdusattar , Li Di
Published: December 2024

Fast radio bursts (FRBs) are bright radio transients with millisecond durations, which typically occur at extragalactic distances. The association of FRB 20200428 with the Galactic magnetar SGR J1935+2154 strongly indicates that they could originate from neutron stars, which naturally leads to the expectation that periodicity connected with the spinning of magnetars should exist in the activities of repeating FRBs. However, previous studies have failed to find any signatures supporting such a conjecture. Here we perform a thorough search for short-timescale periodicity in the four most active repeating sources, i.e., FRBs 20121102A, 20200120E, 20201124A, and 20220912A. Three different methods are employed, including a phase folding algorithm, the H-test, and Lomb–Scargle periodograms. For the three most active repeaters from which more than 1000 bursts have been detected, i.e., FRBs 20121102A, 20201124A, and 20220912A, more in-depth period searches are conducted by considering various burst properties such as the pulse width, peak flux, fluence, and the brightness temperature. No clear periodicity is found in a period range of 0.001–1000 s in all efforts. Implications of such a null result on the theoretical models of FRBs are discussed.

Published: December 2024

The Faraday rotation effect, quantified by the rotation measure (RM), is a powerful probe of the large-scale magnetization of the Universe—tracing magnetic fields not only on galaxy and galaxy cluster scales but also in the intergalactic medium (IGM; referred to as RMIGM). The redshift dependence of the latter has extensively been explored with observations. It has also been shown that this relation can help to distinguish between different large-scale magnetization scenarios. We study the evolution of this RMIGM for different primordial magnetogenesis scenarios to search for the imprints of primordial magnetic fields (PMFs; magnetic fields originating in the early Universe) on the redshift-dependence of RMIGM. We use cosmological magnetohydrodynamic simulations for evolving PMFs during large-scale structure formation, coupled with the light-cone analysis to produce a realistic statistical sample of mock RMIGM images. We study the predicted behavior for the cosmic evolution of RMIGM for different correlation lengths of PMFs, and provide fitting functions for their dependence on redshifts. We compare these mock RM trends with the recent analysis of the the LOw-Frequency ARray RM Grid and find that large-scale-correlated PMFs should have (comoving) strengths ≲0.75 nG, if they originated during inflation with the scale-invariant spectrum and (comoving) correlation length of ∼19 h
−1 cMpc or ≲30 nG if they originated during phase-transition epochs with the comoving correlation length of ∼1 h
−1 cMpc. Our findings agree with previous observations and confirm the results of semi-analytical studies, showing that upper limits on the PMF strength decrease as their coherence scales increase.
The Foundations of Multi-line Molecular Cloud Population Synthesis
Authors: Perry Marissa N. , Sheen Derek , Kauffmann Jens
Published: December 2024

While galactic molecular clouds have been studied in great detail, the spatial resolution of current single-dish radio telescopes inhibits our ability to resolve individual molecular clouds in external galaxies. In this case, the line luminosity signal received is an average over a ≥100 pc diameter beam containing several molecular clouds. This leads us to an interesting question: If we point the telescope beam at a region of molecular clouds in a nearby galaxy, can we meaningfully decompose the unresolved signal we receive? In this work, we formulate theoretical methods of decomposing a galaxy line luminosity signal into its cloud population line luminosity components.
Stable Stratification of the Helium Rain Layer Yields Vastly Different Interiors and Magnetic Fields for Jupiter and Saturn
Authors: Markham S. , Guillot T.
Published: December 2024

At sufficiently high pressures (∼Mbar) and low temperatures (∼103–104 K), hydrogen and helium become partly immiscible. Interpretations of Jupiter’s and Saturn’s magnetic fields favor the existence of a statically stable layer near the Mbar pressure level. From experimental and computational data for the hydrogen–helium phase diagram, we find that moist convection and diffusive convection are inhibited, implying a stable helium rain layer in both Jupiter and Saturn. However, we find a significant difference in terms of structure and evolution: in Jupiter, helium settling leads to a stable yet superadiabatic temperature gradient that is limited by conductive heat transport. The phase separation region should extend only a few tens of kilometers, instead of thousands in current-day models, and be characterized by a sharp increase of the temperature of about 500 K for standard phase separation diagrams. In Saturn, helium rains occur much deeper, implying a larger helium flux relative to planetary mass. We find that the significant latent heat associated with helium condensation implies that a large fraction, perhaps close to 100%, of the planet’s intrinsic heat flux may be locally transported by the sinking helium droplets. This implies that Saturn may possess a much more extended helium rain region. This also accounts, at least qualitatively, for the differences in strength and characteristics of the magnetic fields of the two planets. Dedicated models of magnetic field generation in both planets may offer observational constraints to further refine these findings.
Phase Equilibria of Sub-Neptunes and Super-Earths

Published: December 2024

We investigate the consequences of nonideal chemical interaction between silicate and overlying hydrogen-rich envelopes for rocky planets using basic tenets of phase equilibria. Based on our current understanding of the temperature and pressure conditions for complete miscibility of silicate and hydrogen, we find that the silicate-hydrogen binary solvus will dictate the nature of atmospheres and internal layering in rocky planets that garnered H2-rich primary atmospheres. The temperatures at the surfaces of supercritical magma oceans will correspond to the silicate-hydrogen solvus. As a result, the radial positions of supercritical magma ocean–atmosphere interfaces, rather than their temperatures and pressures, should reflect the thermal states of these planets. The conditions prescribed by the solvus influence the structure of the atmosphere, and thus the transit radii of sub-Neptunes. Separation of iron-rich metal to form metal cores in sub-Neptunes and super-Earths is not assured due to prospects for neutral buoyancy of metal in silicate melt induced by dissolution of H, Si, and O in the metal at high temperatures.

The individual approach in the treatment of heart failure (HF) and personalized medicine have been the main topic in recent years in all scientific forums. The combination of chronic obstructive pulmonary disease (COPD) and sleep apnea (SA) further complicates the clinical presentation in patients with HF. The overlap of all three diseases requires a team of specialists and additional therapeutic approach for better control and to improve the prognosis. A large number of the pathophysiological mechanisms of the three diseases also overlap. The novel therapies for HF have shown good results, both in COPD and CA subgroups. Noninvasive ventilation during hospitalization and at home is an established method in the individual groups. In a combination of the three diseases, definitive data from randomized trials are still lacking.
More than half of the alien plants naturalised in the arid southeast of the Iberian Peninsula could be invasive

Published: December 2024

Having a list of alien plant species naturalised in an area and knowing their invasive potential (i.e. a post-border species risk assessment framework) and the precise locations where they are found, are now a priority as a management strategy to curb their spread, avoiding damage to ecosystems and saving management costs. This is especially important in arid ecosystems, which are particularly vulnerable to impacts due to their limited resources. Weed Risk Assessment systems (WRAs) analyse plant traits that influence their invasive potential through a set of questions whose answers score taxa according to their invasive potential. In this work, we identify potentially invasive plants inhabiting the arid southeast of the Iberian Peninsula, the driest region in Europe, by compiling alien plant species recorded in the wild and applying the Australian and New Zealand Weed Risk Assessment (AWRA) system. The AWRA applies scores that evaluate species characteristics related to biography, undesirable attributes and biology/ecology for establishment elsewhere. We provide the dataset obtained in the application of the AWRA test: a list of the alien plant species naturalised in the study area and their geographical distribution; the answers, scores and results of the test, as well as the scientific sources that support the existence of such characteristics in these species. We found that 64.4% of the 177 taxa assessed can be considered potential invaders. This database represents a useful and transparent tool for environmental managers to deal with the problem of plant invasions effectively. It can also be confronted with data from other areas of the world where these species are naturalised.
Verification of two barracudina species Lestrolepis japonica (Tanaka, 1908) and L. philippina (Fowler, 1934) (Aulopiformes, Paralepididae)
Authors: Ho Hsuan-Ching , Kawai Toshio
Published: December 2024

Examination of the type series of Lestidium japonica Tanaka reveals that the generally accepted concept of this species does not accord with the type series. A historical review of the literature showed that the characterization of L. japonica changed over time, and what has been recognized as “L. japonica” for more than 70 years actually represents a distinct and different species. Among the junior synonyms of “L. japonica”, Paralepis philippinus Fowler, 1934 is resurrected as a valid species herein in a new combination, Lestrolepis philippina. Lestrolepis nigroventralis Ho, Tsai & Li is recognized as a junior synonym of L. japonica herein. Revised diagnostic characteristics for both L. japonica and L. philippina are provided, along with comments on related names to verify their nomenclatural status.
Adult education and The Legacy: recovering undiscovered public knowledge

I opened an antique chest inherited from my great-great uncle and unravelled the strands of his life as an evangelical minister in late 19th-century Italy, unpacking the cover-ups in Britain’s history of Empire and bringing to light the ingenious but ordinary ways in which a handful
of families, even today, shore up their wealth. At the heart of The Legacy is a narrative about suppressed or ‘forgotten’ facts surrounding slavery and Empire, which should be common knowledge, but which must be continually excavated. The ‘undiscovered public knowledge’
concerns land, wealth and inheritance, but primarily land, whose ownership remains resistant to public scrutiny, despite freedom of information (FOI) requests.
Strategic Policy Framework for Ensuring the Sustainability of Essential Healthcare in Korea
Authors: Jung Jaehun
Published: December 2024

South Korea’s rapid economic growth over the past 50 years has significantly improved healthcare outcomes, with life expectancy rising from 62.3 years in the 1970s to 82.7 years in 2022. However, the sustainability of its high-performing healthcare system is increasingly uncertain. Healthcare expenditure as a percentage of GDP reached 9.7% in 2022, surpassing the OECD average, while the fertility rate dropped to 0.72, undermining the system’s demographic foundation. Challenges include freezing health insurance premiums despite rising costs, short-term fiscal injections without thorough evaluation, and expanding the physician workforce without accounting for demographic changes. These policies risk overburdening future generations and escalating systemic financial pressures. To ensure sustainability, a shift in healthcare policy is necessary; from expanding services to managing limited resources and controlling demand. South Korea must adopt a strategic, long-term framework that balances current needs with future sustainability, ensuring its healthcare system remains equitable and resilient.

Drug Allergy Delabeling
Authors: Sim Da Woon
Published: December 2024

Drug allergy labels are critical for ensuring patient safety; however, unverified labels established without a rigorous diagnostic process can lead to suboptimal medication use, treatment failures, increased adverse drug reactions, and higher healthcare costs. In particular, unconfirmed penicillin allergy labels are strongly linked to the inappropriate use of broad-spectrum antibiotics, contributing to the rise of multidrug-resistant infections. The process of drug allergy delabeling enables many patients to safely use the medication in question, thereby facilitating the appropriate use of antibiotics and reducing unnecessary avoidance. Such delabeling is particularly vital as part of antimicrobial stewardship programs, as it enhances patient outcomes while decreasing healthcare expenses. Moving forward, the development of standardized procedures, enhanced awareness among patients and healthcare providers, and the implementation of validated risk-stratification methods is essential for more accurate and efficient drug allergy delabeling. These advancements will help mitigate the adverse effects of inaccurate labels and support optimal patient care.

Published: December 2024

Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated systemic disorder characterized by inflammatory, proliferative, and fibrotic lesions that can affect any body organ. The severity and extent of organ involvement vary significantly among individuals. Diagnosis of IgG4-RD necessitates a comprehensive assessment, including clinical presentation, radiological findings, laboratory tests, and histopathological examination. The 2019 American College of Rheumatology/European League Against Rheumatism classification criteria offer a valuable framework for diagnosing IgG4-RD. Although glucocorticoids and rituximab are the primary treatment options, the optimal long-term management strategy for IgG4-RD remains undetermined.
Bronchoalveolar Lavage and Its Interpretation
Authors: Lee Daegeun , Huh Jin-Young
Published: December 2024

Bronchoalveolar lavage (BAL) is performed via bronchoscopy, typically under conscious sedation. It plays a crucial role in the differential diagnosis of lung disease, because it provides valuable information about the lung parenchyma, including cellular composition, the presence of microorganisms, and cytological features. Furthermore, BAL has therapeutic applications and is widely used in medical research. However, careful patient selection is required, because the diagnostic yield may vary and the procedure has inherent risks.
Percutaneous Kidney Biopsy: A Valuable Diagnostic Tool
Authors: Lee Eu Jin , Choi Dae Eun
Published: December 2024

Percutaneous kidney biopsy is a valuable diagnostic tool for the pathological evaluation of renal diseases, particularly glomerular disorders. It is crucial for guiding treatment decisions when clinical and laboratory findings are uncertain. Since its introduction in the mid-20th century, percutaneous kidney biopsy has evolved from an initial blind approach, associated with higher complication rates, to advanced methods using real-time ultrasound or computed tomography guidance and spring-loaded biopsy needles. These advancements have significantly improved tissue sampling accuracy and minimized complications, establishing percutaneous kidney biopsy as a relatively safe diagnostic procedure. Despite these improvements, the invasive nature of the procedure emphasizes the importance of careful patient selection and operator expertise. Nephrologists, as the primary operators and performers of kidney biopsy, play a pivotal role in ensuring timely and appropriate patient care.

Backgrounds/Aims: The recent increase in medical school admissions has potentially altered the working conditions of hospitalists in South Korea. This study investigated how these changes have affected the work patterns and responsibilities of hospitalists, particularly in light of the ongoing exodus of medical trainees that began on February 22, 2024.Methods: We surveyed members of the Korean Society of Hospital Medicine and the Korean Society of Surgery Hospital Medicine Study Group working as hospitalists from April 2 to 30, 2024. The survey was conducted via email and excluded personally identifiable information. Respondents’ characteristics, work types, hours, patient loads, support staff availability, and changes in job scope post-policy were analyzed.Results: Sixty-three hospitalists responded, with an equitable gender distribution and a median age of 39 years. A significant shift in work patterns was noted, with full-day shifts increasing from 22.2% to 39.7%, and a corresponding decrease in weekday daytime shifts. Work hours also significantly increased from a median of 40 to 45 hours per week. Changes in patient distribution were observed, with fewer hospitalists managing mid-range patient numbers and more handling smaller or larger loads. Despite the increased demands in the latter case, more than 50% of hospitalists reported a lack of support staff and a significant portion did not receive overtime compensation.Conclusions: The increase in medical school admissions and subsequent shifts in hospitalist workloads and hours indicate a strained healthcare system. Hospitalists are taking on more intensive and extended roles. The absence of adequate support staff and adjustments in compensation suggest that further systemic changes are necessary to sustain the efforts of hospitalists, thereby ensuring patient safety and care quality.

La « Commission Agranat » et la guerre du Kippour
Authors: Sentenac Bruno
Published: December 2024

En octobre 1973, Israël est surpris par le déclenchement de la guerre du Kippour. Les services de renseignement de Tel Aviv n’avaient pas vu venir l’attaque qui faillit faire perdre Tsahal. Une Commission d’enquête présidée par le juge Agranat s’efforça d’établir les responsabilités et les lacunes qui provoquèrent cet échec. Une telle tâche est délicate et le parallèle avec le 7 octobre 2023 est tentant.
Les limites du « tapis rouge ». Le cas de l’accès aux soins des exilés issus d’Ukraine en France en 2022
Authors: Joxe Ludovic
Published: December 2024

Pour évaluer la part minimale des entraves aux soins auxquelles peuvent être confrontées les populations exilées, cet article s’appuie sur un cas contre-intuitif et presque idéal-typique de la migration internationale : celui de l’accueil « à bras ouverts » autant par les autorités que par les citoyens français des exilés issus d’Ukraine en 2022. Dans ces conditions, quelles ont été les limites résiduelles de ce « tapis rouge » ? Fondé sur dix-neuf entretiens avec des familles exilées ainsi qu’une trentaine avec des acteurs institutionnels et associatifs dans la métropole lyonnaise, cet article met en évidence la persistance, malgré les mesures d’exception mises en place, de difficultés d’accès aux soins. Certaines sont intrinsèquement associées à l’urgence d’une situation de crise migratoire (non-recours, freins linguistiques, manque d’informations ou restriction des critères d’admission), d’autres, plus structurelles, sont liées au système de santé français (contenu du « panier de soins », délais d’obtention d’un rendez-vous ou frilosité des praticiens), et d’autres enfin, interculturelles, sont à l’origine d’incompréhensions entre les exilés et les acteurs de l’accueil et du soin.
De l’inégalité d’usage des dispositifs de prévention ciblés du VIH entre exilés homosexuels
Authors: Bouchet-Mayer Cyriac
Published: December 2024

La découverte de la fonction préventive des traitements contre le VIH, il y a une quinzaine d’années, réactive peu à peu les stratégies de ciblage populationnel. Les personnes migrantes et les hommes ayant des relations sexuelles entre hommes (HSH) font partie des populations auprès desquelles le dépistage et l’accès aux traitements sont promus dans le but de maîtriser l’épidémie. Cet article repose sur l’ethnographie multisituée d’un dispositif destiné à « aller-vers » les hommes demandant l’asile au motif de l’orientation sexuelle. Il étudie, entre autres, les représentations d’un dispositif étiqueté « LGBT+ migrant » par les personnes à qui il s’adresse, ainsi que le poids des contextes et trajectoires de vie sur les usages du dispositif. Cette analyse montre que les usages dépendent en grande partie des dispositions économiques, scolaires, homosociales et préventives construites au pays et de la manière dont ces dernières agissent à la fois sur les parcours migratoires et les conditions de survie pendant la demande d’asile une fois en France.
Soigner le trauma des migrants dans les centres régionaux de psychotraumatisme : entre enjeu de santé publique et épreuves pratiques
Authors: Le Goff Gwen
Published: December 2024

Les centres régionaux de psychotraumatisme (CRP), créés suite à l’instruction du 19 juin 2018, s’adressent à tous types de victimes d’évènements traumatiques, notamment les personnes migrantes. Si le psychotraumatisme des migrants est aujourd’hui reconnu comme un problème public à part entière nécessitant d’être pris en compte par les services de l’État et les institutions sanitaires, cet article analyse les difficultés que posent l’accueil et la prise en charge des migrants dans les centres régionaux de psychotraumatisme. L’autrice démontre que, si la question de leur prise en charge est moins un enjeu de controverses théoriques qu’elle a pu l’être par le passé, elle reste un sujet de perplexité pratique à l’origine d’un trouble pour les professionnels, dans un contexte de saturation de la psychiatrie. Dans les faits, cet article relève que ce public est accueilli à la marge dans les CRP : en effet les thérapies proposées apparaissent peu adaptées aux personnes en situation de précarité sociale. Si des tentatives d’y remédier se développent, proposant une réponse clinique différenciée pour les personnes migrantes, celles-ci ne sont pas sans poser question : il s’agira ici d’en souligner les logiques, mais aussi les limites.
Performance evaluation metric for statistical learning trading strategies

Published: December 2024

We analyze how the sentiment of financial news can be used to predict stock returns and build profitable trading strategies. Combining the textual analysis of financial news headlines and statistical methods, we build multi-class classification models to predict the stock return. The main contribution of this paper is twofold. Firstly, we develop a performance evaluation metric to compare multi-class classification methods, taking into account the precision and accuracy of the models and methods. By maximizing the metric, we find optimal combinations of models and methods and select the best approach for prediction and decision-making. Secondly, this metric enables us to construct profitable option trading strategies, which can also be used as an assessment tool to analyze models' prediction power. We apply our methodology to historical data from Apple stock and financial news headlines from Reuters from January 1, 2012 to May 31, 2019. During validation (May 31, 2018, to May 31, 2019), our models consistently outperformed the market, with two-class one-stage models yielding returns between 30% and 45%, compared to the S & P500 index's 1.73% return over the same period.
