Kulturális eltérések értelmezése Dél-Koreában magyar szemmel
Authors: Milassin Anda Nóra 
Published: March 2021

Az új kultúrákkal való találkozás és az egyének beilleszkedésének folyamata önmagában is érdekes kutatási terület, de az különösen, hogy azonos kultúra tagjai más kultúrákat mi alapján találnak vonzónak, míg más kultúrák semleges vagy épp negatív érzéseket keltenek bennük. A „vonzó” kultúrák otthonos érzést adnak a magyar kultúra tagjának, míg a „taszító” kultúrákban az egyén szinte elképzelhetetlennek tartja a szoros viszonyt a két kultúra között. Azevedo (2011) kutatásai alapján tudjuk, hogy hatalmas kulturális különbségek ellenére is zökkenőmentes lehet az együttműködés két kultúra tagjai között, de két kultúra találkozása mindig hatással van az egyénekre. A kutatás ezeket a kulturális hatásokat és a vonzó/taszító kulturális jellegzetességeket vizsgálja. A tanulmány a dél-koreai kultúra magyar szempontból való mélyebb megértésére irányuló kutatás eredményeit mutatja be. A magyar kultúra tagjait kérdezte a koreai kultúrában megélt élményeikről, tapasztalataikról, gondolataikról. Földrajzilag két igen távoli kultúráról van szó, amelyek történelme, értékei, hagyományai merőben eltérőek. A kutatási előfeltevés szerint a markáns kulturális különbözőségeket a két kultúrában mélyen kódolt értékek adják, amelyek a kultúra tagjainak cselekedetein keresztül megismerhetők. A tanulmány a dél-koreai és a magyar kultúra találkozásakor megtapasztalt kulturális eltérések értelmezését mutatja be a kétkultúra együttműködési hatékonyságának a javítása érdekében.

Published: March 2021

Abstract
We present the analysis of the diffuse, low column density H i environment of 18 MHONGOOSE galaxies. We obtained deep observations with the Robert C. Byrd Green Bank Telescope and reached down to a 3σ column density detection limit of N
HI = 6.3 × 1017 cm−2 over a 20 km s−1 line width. We analyze the environment around these galaxies, with a focus on H i gas that reaches column densities below N
HI = 1019 cm−2. We calculate the total amount of H i gas in and around the galaxies, revealing that nearly all of these galaxies contained excess H i outside of their disks. We quantify the amount of diffuse gas in the maps of each galaxy, defined by H i gas with column densities below 1019 cm−2, and find a large spread in percentages of diffuse gas. However, by binning the percentage of diffuse H i into quarters, we find that the bin with the largest number of galaxies is the lowest quartile (0%–25% diffuse H i). We identified several galaxies that may be undergoing gas accretion onto the galaxy disk using multiple methods of analysis, including azimuthally averaging column densities beyond the disk, and identifying structure within our integrated intensity (moment 0) maps. We measured H i mass outside the disks of most of our galaxies, with rising cumulative flux even at large radii. We also find a strong correlation between the fraction of diffuse gas in a galaxy and its baryonic mass, and we test this correlation using both Spearman and Pearson correlation coefficients. We see evidence of a dark matter halo mass threshold of M
halo ∼ 1011.1
M
☉ in which galaxies with high fractions of diffuse H i all reside below. It is in this regime that cold-mode accretion should dominate. Finally, we suggest a rotation velocity of v
rot ∼ 80 km s−1 as an upper threshold to find diffuse-gas-dominated galaxies.
A Physical Model for a Radiative, Convective Dusty Disk in AGN
Authors: Dorodnitsyn A. , Kallman T. 
Published: March 2021

Abstract
An accretion disk in an Active Galactic Nucleus harbors and shields dust from external illumination. Our model shows that, at the midplane of the disk around an M
BH = 107
M
⊙ black hole, dust can exist at 0.1 pc from the black hole, compared to 0.5 pc outside of the disk where such self-shielding is constrained. We construct a physical model of a disk region approximately located between the radius of dust sublimation at the disk midplane and the radius at which dust sublimes at the disk surface. Our main conclusion is that, for a wide range of model parameters such as local accretion rate and/or opacity, the accretion disk’s own radiation pressure on dust significantly influences its vertical structure. In this region, convection plays important role in the vertical transport of energy. When the local accretion rate exceeds 2.5M
⊙ yr, the 10−2 pc scale disk is supercritical with respect to dust opacity. Such a disk puffs up and transforms from geometrically thin to slim. Our model fits into the narrative of a “failed wind” scenario of Czerny & Hryniewicz and the “compact torus” model of Baskin & Laor, incorporating them as variations of the radiative dusty disk model.
Source-dependent Properties of Two Slow Solar Wind States

Published: March 2021

Abstract
Two states of the slow solar wind are identified from in situ measurements by the Parker Solar Probe (PSP) inside 50 solar radii from the Sun. At such distances the wind measured by PSP has not yet undergone significant transformation related to the expansion and propagation of the wind. We focus in this study on the properties of the quiet solar wind with no magnetic switchbacks. The two states differ by their plasma beta, flux, and magnetic pressure. PSP’s magnetic connectivity established with potential field source surface reconstructions, tested against extreme ultraviolet and white-light imaging, reveals the two states correspond to a transition from a streamer to an equatorial coronal hole. The expansion factors of magnetic field lines in the streamer are 20 times greater than those rooted near the center of the coronal hole. The very different expansion rates of the magnetic field result in different magnetic pressures measured by PSP in the two plasma states. Solar wind simulations run along these differing flux tubes reproduce the slower and denser wind measured in the streamer and the more tenuous wind measured in the coronal hole. Plasma heating is more intense at the base of the streamer field lines rooted near the boundary of the equatorial hole than those rooted closer to the center of the hole. This results in a higher wind flux driven inside the streamer than deeper inside the equatorial hole.
SiO, 29SiO, and 30SiO Emission from 67 Oxygen-rich Stars: A Survey of 61 Maser Lines from 7 to 1 mm

Published: March 2021

Abstract
Circumstellar environments of oxygen-rich stars are among the strongest SiO maser emitters. Physical processes such as collisions, infrared pumping, and overlaps favor the inversion of level population and produce maser emission at different vibrational states. Despite numerous observational and theoretical efforts, we still do not have a unified picture including all of the physical processes involved in SiO maser emission. The aim of this work is to provide homogeneous data in a large sample of oxygen-rich stars. We present a survey of 67 oxygen-rich stars from 7 to 1 mm, in their rotational transitions from J = 1 → 0 to J = 5 → 4, for vibrational numbers v from 0 to 6 in the three main SiO isotopologs. We have used one of the 34 m NASA antennas at Robledo and the IRAM 30 m radio telescope. The first tentative detection of a v = 6 line is reported, as well as the detection of new maser lines. The highest vibrational levels seem confined to small volumes, presumably close to the stars. The J = 1 → 0, v = 2 line flux is greater than the corresponding v = 1 in almost half of the sample, which may confirm a predicted dependence on the pulsation cycle. This database is potentially useful in models which should consider most of the physical agents, time dependency, and mass-loss rates. As a by-product, we report detections of 27 thermal rotational lines from other molecules, including isotopologs of SiS, H2S, SO, SO2, and NaCl.

Published: March 2021

Abstract
We describe 238 mid-infrared detections of supernovae and 195 possible supernovae in co-added images of the NEOWISE mission. We find one type Ia supernova (SN 2015cp), which has a mid-infrared evolution that is similar to known type Ia with long-lived mid-infrared detections. We also find long-lived mid-infrared detections in one type Ic (SN 2017dio) and one type Ib (SN 2016ajo). Additionally we provide measured magnitudes for most of our detections. We also find two transients, which we suspect to be TDEs: ASASSN-18ap and ATLAS17jrp.
Quitter l’Aide sociale à l’enfance
Authors: Dietrich-Ragon Pascale 
Published: March 2021

En France, 138 000 enfants ou adolescents sont pris en charge par l’Aide sociale à l’enfance (ASE) au titre de l’enfance en danger, soit 1,6 % des mineurs. Si les jeunes entrent dans le dispositif à des âges très variés, tous doivent en revanche en sortir à 18 ans, âge de fin de la prise en charge légale, ou à 21 ans maximum s’ils obtiennent un contrat jeune majeur. Ils doivent alors subvenir eux-mêmes à leurs besoins et ne peuvent plus dépendre de l’ASE pour se loger. À partir des données de l’enquête Elap (Étude longitudinale sur l’accès à l’autonomie après le placement) et d’entretiens qualitatifs, cet article explore les modalités et le vécu de la sortie de placement sur le plan résidentiel. Alors que les jeunes ont souffert précocement de la précarité du logement, le départ programmé de l’institution est une nouvelle source d’insécurité résidentielle, qui génère stress et angoisse. Par ailleurs, l’intégration sur le marché immobilier s’effectue de façon inégale. Ceux qui ont accepté de jouer le jeu de l’institution et ne sont pas sortis du circuit institutionnel réussissent à intégrer les meilleurs hébergements, puis un logement autonome. Au contraire, les jeunes qui ne parviennent pas ou ne souhaitent pas se plier aux contraintes institutionnelles sont les plus exposés à la précarité résidentielle à l’issue de leur prise en charge.
Se mettre au football, arrêter le football. Quantifier les contraintes à la pratique des femmes
Authors: Martin Camille 
Published: March 2021

En suivant une tradition de travaux de démographie sportive, nous avons étudié les trajectoires sportives des licencié·es de la FFF. Celles-ci ont été reconstituées sur une période de 26 saisons consécutives (entre 1992 et 2018). La comparaison des carrières des femmes et des hommes permettra de quantifier la force des obstacles qui pèsent sur l’engagement durable des femmes dans le football. Nous montrons en effet que leurs trajectoires sont en moyenne plus précaires que celles de leurs homologues hommes, à l’exception de la période adolescente. Nous proposons des hypothèses d’interprétation de ce phénomène, mêlant différenciation des dispositions sportives et logiques de choix de pratiques culturelles juvéniles.
Análise de dados aplicada às Cidades Inteligentes: reflexões sobre a Região Nordeste do Brasil
Authors: Barbosa Jane Roberta de Assis , Sánchez-Gendriz Ignacio 
Published: March 2021

As cidades inteligentes, como aposta para a gestão urbana, têm despertado a atenção de pesquisadores e gestores públicos ao redor do mundo. Em 2020, na Região Nordeste do Brasil, 36 municípios estão categorizados como “cidades inteligentes”. Este artigo descreve os métodos usados para analisar, visualizar e discutir algumas informações sobre essas 36 cidades. A utilização de mapas temáticos permitiu demonstrar, numa perspectiva espacial, algumas características desses municípios, e sua associação ao uso de métodos de mineração de dados e a uma perspectiva teórica crítica mostrou-se útil para compreender as dinâmicas territoriais das cidades inteligentes. Ao combinar variáveis das cidades pesquisadas, a análise de componentes principais e o agrupamento hierárquico identificaram automaticamente similaridades e diferenças entre elas. Em comparação com as metrópoles e capitais incluídas neste estudo, e tomando-se como referência a REGIC 2007, os resultados mostram-se úteis para identificar as cidades com potencialidades para melhor promover e/ou abrigar dinâmicas territoriais características de cidades inteligentes, que são: Jaboatão dos Guararapes-PE, Olinda-PE, Igarassu-PE, São Lourenço da Mata-PE, Moreno-PE, Itapissuma-PE, que fazem parte da Região Metropolitana de Recife; e Parnamirim-RN, pertencente à Região Metropolitana de Natal.

Published: March 2021

Abstract
Dominant infiltration of neutrophils is a hallmark of many inflammatory diseases, especially in septic shock. IL-1β as one of the most early released proinflammatory cytokine in neutrophil, plays a pivotal role in the progress of sepsis. In this study, we built a high-throughput–compatible drug screen assay platform based on our newly constructed reporter C57BL/6 mice, pIL1-DsRed, expressing the DsRed gene under the control of the IL-1β promoter. After screening 1200 U.S. Food and Drug Administration–approved compounds, we found that pinaverium bromide (PVB) significantly suppressed the DsRed expression of primed neutrophil and improved the survival rate of mice given LPS in an endotoxin challenge analogous to sepsis, regardless of whether PVB was administered before or after LPS. PVB also protected the liver and lung from LPS-induced damage and reduced organ-specific inflammatory responses. PVB decreased the production of IL-1β, IL-6, and CXCL1 mRNA in the lungs of LPS-treated mice and decreased the serum levels of liver transaminases (alanine aminotransferase and aspartate aminotransferase) at multiple time points and doses tested. PVB can significantly suppress primed neutrophil-specific respiratory bursts and migration as well. Lastly, PVB affected neutrophils’ gene expression and phenotypic changes during neutrophil priming. PVB downregulated GM-CSF–induced expression of CD54 and dectin-2 (markers of fully primed neutrophils) at both mRNA and protein levels during late-phase neutrophil priming. In summary, we demonstrated that PVB can be used as a potential therapeutic agent for sepsis by inhibiting neutrophil priming.
Aortic size in children
Authors: Al-mousily Mohammad F. , Lopez Leo , Muniz Juan Carlos , Sasaki Nao , Seltzer Irwin , Gruber Joshua , Welch Elizabeth 
Published: March 2021

Background:
Current guidelines recommended aortic measurements during diastole in adults and during systole in children. Recent studies in adults have demonstrated noteworthy differences in aortic measurements during systole and diastole in the same subjects. In the present study, we aimed to characterize systolic and diastolic differences in aortic measurements in healthy children.

Materials and Methods :
This retrospective study included 272 children who had a complete echocardiogram and no heart disease. Aortic measurements at the annulus (ANN), aortic root (AOR), sinotubular junction (STJ), and ascending aorta (AAO) were performed. Systolic and diastolic values were compared by calculating the mean systolic to diastolic (SD) percent difference for each segment; if the SD difference was >5%, it was considered clinically important. Similar measurements were conducted by another observer in 18% of the subjects.

Results:
Systolic measurements were larger than diastolic measurements with mean SD percent differences >5% (P < 0.001) for the AOR (7.3% ± 5.5%), STJ (10.24% ± 7.1%), and AAO (9.8% ± 7.4%). There was no clinically significant SD difference for the ANN. There was an excellent intraclass correlation coefficient between observers (0.982–0.995).

Conclusions:
Systolic measurements for the AOR, STJ, and AAO were larger than diastolic measurements. Normal reference values are utilized to design treatment for patients with abnormal aortic sizes, and the timing in the cardiovascular cycle used to decide the reference values should be equivalent to the timing used to make measurements in clinical practice. This is particularly imperative as patients transition their care from a pediatric to an adult cardiologist.

Authors: Sharma Supriya , Garla Bharath K. , Dagli Rushabh J. , Khan Mohsin , Das Mayank , Dar Ajaz 
Published: March 2021

Introduction:
In the past three to four decades, improvements in dialysis and transplantation have reduced morbidity and mortality among patients with end-stage renal disease. The present study was conducted to establish the relationship of sociodemographic conditions, state of dental health, periodontal tissue, and soft tissue in patients with duration of hemodialysis.

Materials and Methods:
A cross-sectional study using a self-administrated structured questionnaire was conducted among hemodialysis patients in Jodhpur city from March 2019 to June 2019. The final sample was 133 hemodialysis patients. The questionnaire was pretested on a group of ten patients to check the feasibility of the study and to ensure the face validity of the questionnaire.

Results:
It was found that patients with more than 3 years on dialysis had a statistically significantly higher prevalence of decayed teeth. There was a strong correlation between length of time on Hemodialysis and decayed, probing pocket depth, clinical attachment level, periodontal indices, gingival index, bleeding on probing, and gingival recession.

Conclusion:
Awareness must be raised among dialysis patients, nephrologists, and dentists about the need for primary dental prevention.
Disordered Iron Homeostasis Among Nigerians with Chronic Heart Failure
Authors: Akintunde Adeseye Abiodun , Akinlade Mathias Olawale , Aworanti Oladapo Wale 
Published: March 2021

Background:
Iron deficiency (ID) often coexists with heart failure and has recently become a therapeutic option in its management. Multiple markers are often required to adequately estimate iron status. This study was aimed at describing the status of iron homeostasis among heart failure patients in Nigeria.

Materials and Methods:
This was a cross-sectional study done at two tertiary centers in Nigeria. One hundred and forty patients with a diagnosis of heart failure were recruited into the study. Full blood count, total serum iron, total iron-binding capacity, and serum ferritin were measured. Anemia was defined by standardized criteria. Data analysis was done with SPSS 20.0.

Results:
The mean age of the study patients was 62.96 ± 16.34 years. Disordered iron homeostasis was common, often characterized by predominantly low total serum iron and low transferrin saturation in the presence of normal or high serum ferritin. ID was reported in 60.0% of all patients including 61.3% of anemic and 51.9% of nonanemic patients, P = not significant. High ferritin level was documented in fifty (35.7%) patients (36.8% anemic vs. 32.4% nonanemic patients, P = 0.40). Pulmonary hypertension was more frequent among anemic patients found in 45 patients (including 42.5% of anemic vs. 8.8% of nonanemic patients). ID was associated with poor functional status including ejection fraction, deranged renal function, and advanced disease.

Conclusion:
Functional ID is very common among heart failure patients in Nigeria irrespective of their anemia status. It is associated with poor functional status and may be a potential therapeutic strategy in Africans with heart failure.
Whatsapp as an E-Learning Tool of Dental Radiograph Interpretation Among Dental Undergraduates - A Pilot Study
Authors: Bagewadi Anjana 
Published: March 2021

Background:
The number of smartphone users and social media has increased exponentially. The applications have been used for teaching, learning, and assessment. WhatsApp allows sharing of images with multiple users and is a great platform for discussions. Hence, it was decided to teach interpretation of intra-oral periapical radiographs (IOPA) for dental undergraduates.

Aim:
The study aimed to know the perception and acceptability for WhatsApp as an e-learning tool for learning IOPA radiograph interpretation.

Methodology:
Seventy-five third year students of Bachelor of Dental Surgery participated in the study. They were further grouped into smaller groups, containing 7-8 students in one batch. Every student made and posted five IOPAs images with interpretation in the WhatsApp group. The next day, the facilitator clarified the doubts. At the end of the posting, students answered a questionnaire with a 4-point Likert scale of 10 items. The analysis was done manually by calculating aggregate percentages of responses.

Results:
98.6% of students felt WhatsApp facilitates group discussion and provides the flexibility of time. 96% of students agreed that it encourages participation. 89% felt it helped them clear doubts.

Conclusion:
All the students participated enthusiastically. They could learn at their convenient time and without the fear of face-to-face interaction. Hence, WhatsApp can be an adjunct teaching methodology for interpretation of IOPA.
