Abstract

Objectives
Hemoglobin and creatinine levels are important factors for contrast induced nephropathy (CIN) development. Our aim in this study is to investigate the predictive value of hemoglobin to creatinine ratio for CIN development in patients with percutaneous coronary intervention (PCI).

Methods
A total of 500 patients who underwent PCI in our clinic were evaluated prospectively in terms of CIN. Hemoglobin to creatinine ratio is calculated as baseline hemoglobin/baseline serum creatinine value. glomerular filtration rate (GFR) was calculated with Cockcroft-Gault formula. The definition of CIN includes absolute (≥0.5 mg/dL) or relative increase (≥25%) in serum creatinine at 48–72 h after exposure to a contrast agent compared to baseline serum creatinine values.

Results
CIN was detected in 13.8% (69 patients) of 500 patients. In multivariate lineer regression analysis, hemoglobin to creatinine ratio (beta: −0.227, p=0.03) and ejection fraction (EF) (beta: −0.161, p<0.001), contrast amount used (beta: 0.231, p<0.001) were found to be significant predictors for the development of CIN. In receiver operating characteristics (ROC) analysis; AUC=0.730 (0.66–0.79) for hemoglobin to creatinine ratio, p<0.001, AUC=0.694 (0.62–0.76) for EF, p<0.001 and AUC=0.731 (0.67–0.78) for contrast amount used p<0.001.

Conclusions
Hemoglobin to creatinine ratio, EF and contrast amount used were independent predictors for CIN development in patients with PCI (NCT04703049).

Abstract
We present the findings of an extensive examination on newly designed CdO-rich and transparent glass shields for nuclear medicine facilities in lieu of traditional and unfavorable materials, such as lead and concrete. Gamma-ray transmission factors of newly designed glass shields are determined using a variety of diagnostic, therapeutic, and research radioisotopes, including 67Ga, 57Co, 111In, 201Tl, 99mTc, 51Cr, 131I, 58Co, 137Cs, 133Ba, and 60Co. A general-purpose Monte Carlo code MCNPX (version 2.7.0) is used to determine the attenuation parameters of different material thicknesses. Next, the findings are compared using a standard concrete shielding material. The results indicate that adding more CdO to the glass composition improves the overall gamma-ray attenuation properties. As a result, among the heavy and transparent glasses developed, the C40 sample containing 40% CdO exhibited the best gamma-ray absorption properties against all radioisotopes. Furthermore, the gamma-ray absorption characteristics of this created high-density glass were shown to be better to those of a standard and heavy concrete sample. It can be concluded that the newly developed CdO-rich and transparent glass sample may be used in medical radiation fields where the radioisotopes examined are used in daily clinical and research applications.
The effect of expanded polystyrene beads (EPS) on the physical and mechanical properties of aerated concrete

Published: June 2022

Abstract
There is a significant challenge to developing the strength and durability of the aerated concrete (AC) for structural applications, but to date, no researchers have focussed on the effect of expanded polystyrene beads (EPS) on the AC properties. EPS-AC consists of cement, sand, water and aluminium powder with commercially available spherical small, hollow and impermeable polystyrene beads. In this research, different contents of EPS from 0 to 4% by cement weight were added to create the AC with different densities. It is revealed that the greatest enhancements in the properties of EPS-AC were noticed when the EPS volume fraction was increased to 4%. The compressive, flexural strength and modulus of rupture were enhanced by 48, 37 and 125% respectively, whereas the density was raised slightly. Moreover, it was shown that all EPS-AC mixes could satisfy the requirements of structural lightweight concrete.
Two Sides of the Same Coin? Race, Racial Resentment, and Public Opinion Toward Financial Compensation of College Athletes
Authors: Wallsten Kevin J. , Nteta Tatishe M. , McCarthy Lauren A. 
Published: June 2022

Abstract
The last decade has seen a series of high-profile battles over the rights of college athletes take place in the nation’s courthouses and state legislatures, and on the floor of the U.S. Congress. How has the public responded to these changes and how do they formulate their views on policies that seek to provide additional financial compensation and employment protections to college athletes? Using six years of nationally representative polling data on NCAA reform, we find that public opinion on the financial rights of college athletes and the NCAA’s treatment of its athletes follows the same trajectory as so much else in American social, political and cultural life—massive racial differences in how people understand the issue and a growing polarization among whites based on ideology and racial attitudes. More specifically, we find that while support for NCAA reform among African Americans and white conservatives inched incrementally upwards between 2014 and 2020, support among white liberals increased exponentially. As we explain, this asymmetrical increase in support has much to do with the rapidly evolving racial attitudes of white liberals. Indeed, we show that racial attitudes are the largest and most important determinant of support for the three most commonly discussed reforms to the NCAA: “pay for play,” name, image and likeness rights (NIL), and unionization protections. In short, opinions about the future of college athletics have as much to do with race and racial attitudes as they do with sports and education.

Published: June 2022

Abstract
Strength loss caused by fungal degradation is an important factor to be considered during tree-stability assessment. Detailed information on the relationship between static mechanical properties in relation to the heterogeneity of density and dynamic mechanical parameters of wood degraded by the soft-rot fungus Kretzschmaria deusta can improve the understanding of its decay process and the interpretation of results obtained from stress-wave-based non-destructive methods used for tree-stability assessment. This research presents density profiles of artificially inoculated samples with K. deusta and static mechanical properties of green beech wood in relation to physical parameters (density, moisture content, vibroacoustic parameters). A statistically relevant difference (p < 0.01) in the variability of density distribution between degraded and intact samples was proved. Relevant correlations were proved among modulus of rupture (

Published: June 2022

Abstract
The microstructural evolution during natural ageing and artificial ageing treatment has been quantified in Al–Cu–Li alloys with Cu/Li ratios of 2.3 and 3.9. Methods including various ageing, hardness testing, transmission electron microscopy and differential scanning calorimetry were employed. The precipitation of T1 (Al2CuLi) phase was confirmed for the first time in the high Li content alloy under natural ageing treatment for 5 months, while the Li-lean alloy exhibits barely any precipitation at room temperature. Under artificial ageing, the Li-rich alloy exhibits a significant increase in hardness due to the formation of high density spherical δ′ phase. On the other hand, the increasing Cu/Li ratio promotes the precipitation of the Cu containing precipitates T1 and θ (Al2Cu), the high Cu/Li ratio (3.9) alloy shows a recovery of ductility, with a uniform elongation of ∼20 %, which is caused by the strong interactions between the dislocations and the nano-scale T1 and θ precipitates. Meanwhile, as the main strengthening precipitate changes from θ and T1 to T1 alone with prolonged ageing time, the alloy displays a double-peak age hardening behavior. This work sheds light on the design of high strength and ductile Al–Li alloys through the well-controlled T1 phase precipitation.
Megvenni vagy megélni? - Magyar Z generációs fiatalok luxus észlelése
Authors: Kucsera Melitta , Neulinger Ágnes 
Published: June 2022

A TANULMÁNY CÉLJA
Jelen tanulmány a Z generáció luxus észlelését térképezi fel kitérve a közösségi média szerepére a luxusról kialakult kép vonatkozásában. Kutatási kérdésünk az volt, hogy a Z generáció által is követett magyar véleményvezérek milyen módon mutatták be a luxust az Instagramon a pandémia előtt és alatt, valamint a Z generáció hogyan észleli és interpretálja a luxust, továbbá termék- vagy élményközpontúság jellemezi percepciójukat.
ALKALMAZOTT MÓDSZERTAN
Kétlépcsős kutatásunk során először magyar, 1995 és 2010 között született, népszerű Instagram influenszerek posztjainak kvalitatív tartalomelemzését végeztük el. A második szakaszban 4 darab 4 fős mini fókuszcsoportos interjú került lebonyolításra.
LEGFONTOSABB EREDMÉNYEK
A vizsgált fiatalok luxus percepciójában meghatározó - mind a tartalomelemzés, mind az interjúk alapján - az élményközpontúság. Az elemzésbe bekerült fiatal magyar influenszerek Instagram posztjaiban exkluzív szabadidős aktivitások jelentek meg, továbbá öltözködésükben kiegészítők formájában, valamint autók és műszaki cikkek megjelenítésével köszöntek vissza a luxusmárkák. A luxus közvetítésénél jelentős különbség nem volt a pandémia előtti és alatti időszak között. A fókuszcsoportokban feltárásra kerültek a luxus fő karakterisztikái a Z generáció luxus észlelése szerint. A résztvevők luxusfogyasztásának funkcióinál megjelent a hasznosság és a hedonizmus, továbbá a másokra irányuló, az egyénre irányuló és a költségalapú értékek. Kiderült, hogy a megkérdezett fiatalok a tapasztalati luxusra vágynak inkább a személyes luxuscikkekkel szemben.
GYAKORLATI JAVASLATOK
A Z generációs fiatalok részéről nyitottság mutatkozott az élményorientált luxus iránt. Eredményeink szerint a csoportot érdemes influenszer marketinggel megszólítani, de csak hiteles, valódi luxustartalommal. Erre ugyanis erős inspirációként tekintenek, a korai vágykeltés pedig segíthet a luxusiparnak a jövőbeni luxusfogyasztói bázis biztosításában. Kutatásunk alapján javasolható, hogy a Z nemzedéket célzó luxusmarketingben érdemes hangsúlyt helyezni arra, hogy a fiatalok a presztízstermékkel és luxusélményekkel saját sikerük megerősítését és identitásuk kifejezését élhetik meg.

Published: June 2022

Objetivo: Comprender las experiencias cotidianas que tienen las personas con discapacidad visual, las barreras o facilitadores para su inclusión social. Métodos: Estudio cualitativo exploratorio. Se realizaron entrevistas semi-estructuradas vía telefónica, dada la condición de pandemia por la covid-19, a personas con baja visión y ceguera de Bogotá, Arauca, Bucaramanga y Piedecuesta. Para el proceso de análisis, se utilizó el diseño metodológico desde Taylor y Bogdan. Resultados: Emerge una categoría central: La inclusión la hacemos todos: Visibilizar la diversidad y las capacidades en los escenarios de la vida cotidiana. La inclusión ha estado atravesada por una lucha constante que han tenido que asumir en los diferentes espacios donde desarrollan su cotidianidad; se identifican dos escenarios críticos: el educativo y el laboral, pues son aquellos en los cuales las personas se han visto enfrentadas a un mayor número de prejuicios, estereotipos y temores. Por su parte el arte y el deporte son espacios que les han permitido romper con los imaginarios negativos de imposibilidad y por otro afianzar su autoconcepto Conclusión: Los hallazgos dan cuenta de que aún persisten miradas limitantes que conviven simultáneamente, lo cual ha dificultado la superación de esquemas ligados a una historia de beneficencia y caridad, afectando la inclusión social de las personas con discapacidad visual.

Háttér és célkitűzések
A serdülők társas készségeinek fejlesztése és társadalmi tudatosságának növelése hozzásegítheti a diákokat ahhoz, hogy közösségük aktív és felelős tagjává váljanak. A Megtartó Közösségek Program kétnapos, intenzív tréning, mely a nem formális tanulás és az élménypedagógia eszközei segítségével kívánja támogatni a diákok szociális fejlődését. Célterületei közé tartozik a perspektívaváltás, az inkluzív szociális identifikáció, az énhatékonyság támogatása, az előítéletek csökkentése és a kollektív cselekvési szándék facilitálása. Jelen tanulmány a program hatékonyságvizsgálatát mutatja be.

Módszer
Az adatgyűjtés 2019 és 2021 zajlott 14–18 éves Baranya megyei diákok bevonásával (N = 296). Ismételt méréses vizsgálati és kontrollcsoportos elrendezésben a résztvevők 2–4 hét különbséggel töltötték ki a program célterületeire fókuszáló kérdőívcsomagot.

Eredmények
A vizsgálat eredményei alapján a Megtartó Közösségek Program eredményesen növeli a serdülők perspektívaváltási képességét, észlelt társas énhatékonyságát, a roma emberek elfogadását és a hátrányos megkülönböztetés csökkentésére irányuló kollektív cselekvési hajlandóságát.

Következtetések
Eredményeink rámutatnak arra, hogy a program alkalmas a társas-társadalmi készségek célzott fejlesztésére. A mérsékelt hatáserősségek mentén megfogalmazható, hogy a jelentős intervenciós hatás eléréséhez komplex, hosszabb időtartamú beavatkozások szükségesek.
Oktatási reform hatékonyságának vizsgálata – Tantárgyak nehézségi elemzése IRT-modell segítségével programtervező informatikus hallgatók körében

Published: June 2022

A felsőoktatási képzéseken megjelenő nagyarányú (általánosságban véve 30–40%-os) hallgatói lemorzsolódás súlyos problémákat okoz. Különösen érintett az informatikaoktatás, a legtöbb ország alapképzésének első két féléve a legkritikusabb: az intézmények elveszíthetik hallgatóik 60%-át. Vizsgálatunk célja annak feltárása, hogy a lemorzsolódás megelőzése érdekében bevezetett oktatási reform 2016 óta milyen mértékben befolyásolja a hallgatók egyetemen történő bennmaradását.
Programtervező informatikus hallgatók tanulmányi eredményeinek mintáját elemeztük 2010 és 2017 között az IRT-modell segítségével. A vizsgálatban 3673 egyetemi hallgató adatai szerepelnek.
Eredményeink szerint az oktatási reform után a legtöbb tantárgy teljesíthetőbbé vált, és az alacsonyabb képességű hallgatók is megpróbáltak vizsgát tenni. A matematikai témájú tantárgyak alacsonyabb nehézségi szinten is teljesíthetővé váltak, illetve alacsonyabb képességszintű hallgatók is vállalták a vizsgák megpróbálását, nem látták eleve kudarcnak a próbálkozást. A programozási/szakmai tárgyak nehezebbekké, komolyabb tárgyakká váltak, és megőrizték differenciálóképességüket. A hallgatók egyetemi előrehaladását segítő oktatási reform lehetővé tette a hallgatók tanulmányi teljesítményének javulását, ami arra enged következtetni, hogy érdemes beavatkozásokat eszközölni az egyes szakok képzési rendszerében.
Factors associated with seropositivity to Aino virus among sheep and goats in South Korea
Authors: Hwang Jeong-Min , Ga Yun Ji , Yeh Jung-Yong 
Published: June 2022

Abstract
Aino virus infection is responsible for epizootic and/or sporadic outbreaks of abortions, stillbirths and premature delivery among pregnant ruminants. The epizootiology of Aino virus infection is poorly defined in South Korea, therefore our aim was to assess its seroprevalence among sheep and goats. We also wanted to evaluate management and regional risk factors that might influence the frequency of infection. Between 2012 and 2013, 26 of 331 flocks (7.9%) and 139 of 915 heads (15.2%) were found serologically positive. In 2018, when samples were again collected in the same regions, 35 of 308 flocks (11.4%) and 89 of 735 heads (12.1%) showed serum-neutralising antibodies against Aino virus. Our results revealed that the age class and history of reproductive problems in the flocks are connected to an increased risk of being positive. The management risk factor attributes showed that preventive measures, such as the routine application of insecticide in farms, decreased the odds for seropositivity to Aino virus (OR = 0.453, P = 0.001). We observed a significant difference in the individual likelihood of being positive in the southern and western provinces with respect to that in the northern and eastern provinces, respectively (OR = 2.199, P < 0.001 and OR = 2.177, P < 0.001). The results of this study may serve as a basis for future epizootic studies on Aino virus infection in South Korea.
Socio-professional Reintegration Services in the Era of the Covid-19 Pandemic in the Małopolska Region
Authors: Rychły-Mierzwa Anna 
Published: June 2022

Background: The research issues concern the most important aspects of socio-vocational reintegration and rehabilitation services (e.g. instruments of support, barriers of service delivery, effects of activities), cooperation in local communities and the scope of institutional support.
Research objectives: The aim of this article is to present the most important implications of the coronavirus pandemic for socio-vocational reintegration services in reintegration units operating in the Małopolska Region.
Research design and methods: The material constituting the basis for analysis is mainly the results of a survey conducted by the Regional Centre for Social Policy in Kraków in the framework of cyclical monitoring of the social economy sector in the Małopolska Region. 73 Reintegration Units participated in this part of the study out of 122 active ones in the Małopolska voivodeship in 2020.
Results: The analysis makes it possible to conclude that the Covid-19 pandemic and related phenomena in the socio-economic sphere had a strong impact on the current functioning of reintegration units, reduced the scope of possible instruments for socio-occupational activation, which in turn had a negative impact on the results of support. The activities of the reintegration units, hampered by the pandemic, did not receive effective support from the public administration or local partners. The pandemic also limited the possibilities of cooperation between reintegration units in local communities.
Conclusions: The long-term effects of which will probably be felt for an unspecified period of time, in order to improve the quality and effectiveness of socio-occupational reintegration services provided by reintegration units.

O presente trabalho objetivou o desenvolvimento de um livro infantil para a aprendizagem sobre a imunização viral no ensino fundamental. Sendo assim, o objeto de ensino alternativo foi construído através de pesquisa bibliográfica, conteúdo do exemplar, produção do livro e ilustrações, divulgação e coleta de satisfação dos leitores. O desenvolvimento de metodologias lúdico-pedagógicas, como o livro “ Bem-Vindos ao Universo Microscópico” é uma alternativa para amenizar a falta de recursos lúdicos para os alunos, e, em contrapartida, os mesmos terem a oportunidade de assimilar de forma prazerosa, a respeito do seu corpo e de suas células de defesa contra os vírus. Neste intuito, ressalta-se que a literatura infantil é um universo aberto de possibilidades e conteúdos, que a cada dia, novos autores criam metodologias de ensino cada vez mais eficaz e tecnológicas, transformando a aprendizagem através dos livros uma interação de troca de informações entre o sujeito e o meio em que se vive.
