As a means of assisting the selection of promising soil classification systems, a set of criteria were presented and tested. Inside the studied slightly saline plot World Reference Base (WRB) and Hungarian soil classification (HU) were compared at all four levels in terms of class separability, correlation to biomass, parsimony and homogeneity of classes. WRB surpassed HU in terms of the very important homogeneity of classes only, but HU performed better in terms of class separability, correlation to biomass and parsimony of classes. With many possible classification units WRB categorized the soil into a large number of classes, but 67% and 78% of them were single-profile classes at levels 3 and 4, respectively inside the ca 0.9 km2 area.

The amelioration of saline-sodic soil and the rational utilization of irrigation water resources are important environmental problems worldwide, particularly in the arid and semi-arid regions. In o...

With the vocabulary and individual style of János Arany’s folk and historical verses and poems, the author contributed to the reform of the Hungarian literary language and style, and by doing so also to the codification of the Hungarian language. In the paper, the authors briefly describe archaisms, their typology, their function in the literary language, and take their examples from the works of János Arany. Within archaisms, the study also describes a group of archaic concepts, historisms, and their types. The authors also introduce a dictionary of the poetic language of Arany, which was published on the bicentenary of the poet’s birth, and also briefly allude to a few previous attempts to process Arany’s vocabulary. They use the AranySz. (Arany Dictionary) published in 2017 to study archaisms and expressions with important stylistic functions and the educational aspects thereof, mainly in the language of the ballads “A walesi bárdok” (‘The Bards of Wales’) and “Szondi két apródja” (‘The two varlets of Szondi’).

Introduction: COVID–19 significantly affects endoscopic labs’ workflow. Endoscopic examinations are considered high-risk for virus transmission. Objectives: To determine impact of COVID–19 pandemic on Hungarian endoscopic labs’ workflow and on infection risk of endoscopic staff. Method: A nation-wide, cross-sectional online questionnaire was sent to heads of endoscopic labs in Hungary. The average number (with 95% confidence intervals) of upper and lower gastrointestinal endoscopies performed in 2020 was compared to that in 2019. The number of SARS-CoV-2-infected endoscopic staff members and the source of infection was also investigated. Results: Completion rate was 30% (33/111). Neither the number of upper (1.593 [743–1.514] vs. 1.129 [1.020–2.166], p = 0.053), nor that of lower gastrointestinal endoscopies (1.181 [823–1.538] vs. 871 [591–1.150], p = 0.072) decreased in 2020, but both upper and lower gastrointestinal endoscopies’ number decreased by 80% during peak phases. Separate examination room was available in 12% of institutes. Appropriate quality personal protective equipment (PPE) was available during the first and second peak phase in 70% and 82%, respectively. Infection risk stratification by questionnaire and PCR testing was routinely performed in 85% and 42%, respectively. Employee number decreased by 33% and 26% for physicians, and by 19% and 21% for assistants during peak phases, mainly due to age restrictions and COVID care assignments. 32% of assistants and 41% of physicians were infected (associated with inappropriate PPE use in 16% and 18%, respectively). Conclusion: Peak phases’ restrictions increase endoscopic workload afterwards. Despite PPE availability, 15% of employees’ COVID infection resulted from inappropriate PPE use in pre-vaccination era.Bevezetés: A COVID–19-pandémia jelentősen befolyásolta az endoszkópos laboratóriumok működését. Az endoszkópos vizsgálatok nagy vírusátviteli rizikójúnak számítanak. Célkitűzés: A koronavírus-járványnak a magyarországi endoszkópos laborok működésére kifejtett hatásának és az endoszkópos személyzet SARS-CoV-2-fertőzésben való érintettségének felmérése a 2020-as évben. Módszerek: Országos szintű, keresztmetszeti, kérdőíves tanulmányunk során magyarországi endoszkópos laboratóriumok vezetőit kerestük meg online formában. Vizsgáltuk a 2020-ban elvégzett felső és alsó tápcsatornai endoszkópiák számát a 2019-es referenciaévhez viszonyítva (átlag [95%-os konfidenciaintervallum]), továbbá a SARS-CoV-2-fertőzéssel érintett dolgozók számát és fertőződésük potenciális forrását. Eredmények: A megkeresett intézmények 30%-ából érkeztek válaszok (33/111). A referenciaévhez képest sem a felső (1593 [743–1514] vs. 1129 [1020–2166], p = 0,053), sem az alsó tápcsatornai endoszkópos vizsgálatok száma (1181 [823–1538] vs. 871 [591–1150], p = 0,072) nem csökkent, bár a vírushullámoknak megfelelően mindkét vizsgálattípus esetén 80%-ot meghaladó vizsgálatszám-csökkenést tapasztaltunk. Dedikáltan fertőző betegek vizsgálatára kialakított helyiség az intézetek 12%-ában állt rendelkezésre. A védőfelszerelések az első és a második hullám alatt 70%-ban, illetve 82%-ban voltak mennyiségileg és minőségileg megfelelőek. A vizsgálat előtt fertőzöttségirizikó-stratifikáció az intézetek 85%-ában, míg PCR-vizsgálat csupán 42%-ukban történt minden esetben. Az első és második járványhullám alatt a dolgozói létszám az orvosoknál 33%-kal, illetve 26%-kal, az asszisztenseknél 19%-kal, illetve 21%-kal csökkent, elsősorban életkori korlátozás, COVID-ellátásba való áthelyezés miatt. Az asszisztensek 32%-a, az orvosok 41%-a esett át COVID-fertőzésen, 16%-ban, illetve 18%-ban nem megfelelő védőfelszerelés-használattal összefüggésben. Következtetés: A járványhullámok alatti restrikciók feloldását követően a vizsgálati terhelés emelkedik. A SARS-CoV-2-vakcinák elérhetősége előtt az endoszkópos laborok dolgozóit érintő COVID-fertőzések 15%-a nem megfelelő védőfelszerelés-használattal volt összefüggésbe hozható.

Összefoglaló. Bevezetés: A gyulladásos bélbetegségek kezelésében a tumornekrózisfaktor-alfa-ellenes (anti-TNFα) antitestek elsődleges választási lehetőséget jelentenek a kortikoszteroid- és immunmoduláns kezelésre refrakter páciensek kezelési stratégiájában. Ezek a hatóanyagok hatékonyak, ám hosszú távú hatásosságukkal kapcsolatban sok az ellentmondás. Célkitűzés: Vizsgálatunk célja megvizsgálni az anti-TNFα-terápia (infliximab [IFX], adalimumab [ADA]) hosszú távú hatékonyságát gyulladásos bélbetegek körében. Módszerek: Retrospektív, adatgyűjtéses vizsgálatunkba a Szegedi Tudományegyetem I. Sz. Belgyógyászati Klinikáján gondozott, 18–65 év közötti gyulladásos bélbetegeket vontunk be. Az adatgyűjtést a Klinika informatikai rendszeréből végeztük a betegek ambuláns megjelenéseinek kezelőlapjaiból, illetve a zárójelentésekből. Eredmények: 102 beteg adatait elemeztük (Crohn-beteg: 67 fő, colitis ulcerosás: 35 fő). A Crohn-betegség diagnózisát követően átlagosan 7,84 év, a colitis ulcerosa diagnózisát követően átlagosan 9,86 év telt el az első anti-TNFα-terápia elkezdéséig. Az első kezelési ciklus átlagosan 2,64 évig tartott, a ciklus végén az IFX-t kapó betegek 50%-ánál, az ADA-t kapó betegek 46%-ánál volt remisszióban a betegség. A második kezelési ciklus átlagosan 4,67 évig tartott, a ciklus végén az IFX-t kapó betegek 36%-a, az ADA-t kapó betegek 40%-a volt remisszióban. Az első, illetve a második kezelési ciklus alatt az allergiás reakciók gyakorisága IFX esetében 13% és 18%, ADA esetében 4% és 3% volt. A primer hatástalanság és a másodlagos hatásvesztés az első ciklusban IFX esetében 4% és 10,5%, ADA esetében 11,5% és 19% volt. A második kezelési ciklusban IFX esetében 9%-ban és 18%-ban, ADA esetében 23%-ban és 10%-ban jelentették a ciklus végét. Következtetés: Az anti-TNFα-terápiák eredményeink alapján hosszú távon is hatékonynak és biztonságosnak bizonyultak. Másodlagos hatásvesztés kisebb arányban fordult elő a vizsgált populációban az irodalmi adatokhoz képest. Orv Hetil. 2020; 161(47): 1989–1994. Summary. Introduction: Anti-tumor necrosis factor-alpha (anti-TNFα) treatment is reserved for steroid-dependent or steroid/immunomodulator-refractory inflammatory bowel diseases patients. These agents are effective, however, their long-term safety is still questionable. Objective: We aimed to assess the long-term efficacy and safety of two anti-TNFα therapies. Methods: In our retrospective study, we reviewed medical records via the administration system of the First Department of Medicine, University of Szeged. Female and male patients, aged between 18–65 years who received anti-TNFα therapy between 2010–2019 were enrolled. Results: 102 patients with inflammatory bowel disease were enrolled (Crohn’s disease: 67, ulcerative colitis: 35). The first anti-TNFα therapy was introduced after an average 7.84 and 9.86 years from diagnosis of Crohn’s disease and ulcerative colitis. The first treatment period lasted for 2.64 years; 50% of patients receiving IFX and 46% of patients receiving ADA were in remission at the end of the period. The second treatment period lasted for 4.67 years, 36% of IFX-treated patients and 40% of ADA-treated patients were in remission at the end of the period. 13% and 18% of patients treated by IFX and 4% and 3% of patients treated by ADA experienced infusion reaction during the first and the second treatment period. Primary non-response and loss of response rates were 4% and 10.5% (IFX) and 11.5% and 19% (ADA) during the first treatment period. These rates were 9% and 18% (IFX) and 23% and 10% (ADA) during the second treatment period. Conclusion: Our study confirmed the long-term efficacy and safety of the anti-TNFα therapies. Loss of response rate is lower in our population compared to the literature. Orv Hetil. 2020; 161(47): 1989–1994.

On 19.07.2020 died a geographer and terminologist, a graduate and lecturer at the University of Tartu and the founder of the Mari national cartography Yuri Vitalievich Gordeev (Estonian: Jüri Gordejev). Regional, national and linguistic aspects were main in his activities in geography and cartography. In his master’s thesis, Gordeev dealt with the problems of the national identity of the Eastern Mari. He worked as a lecturer at the Narva College of the University of Tartu and as a teacher of geography at the Narva Pähklimäe gymnasium. During the Narva period were completed his projects started in Tartu. The most important work of Yuri Gordeev is the map of the Republic of Mari El published in 2008, which consists only of Mari toponyms. A year later in 2009 Yuri Gordeev published a map of the Mari pagan groves. Gordeev took part in the projects of the Finnish Finno-Ugrist Seppo Lallukka. He was also involved in the compilation of terminological textbooks.

A series of bent-core liquid crystals possessing the azocinnamoyl unit in both elongating side arms was synthesized. The chain length was kept fixed for each molecule (C12H25), whereas the substituents at the central and outer rings were varied. The LC phases were assigned by polarizing optical microscopy, differential scanning calorimetry and X-ray diffraction. The investigated compounds are suitably diverse to reveal some aspects of the relationship between molecular structure and the mesomorphic properties. Namely, non-substituted parent compound is crystalline only and the methyl group in position 2 or the chlorine atom in position 4 of the central ring suppresses LC phase formation. Introduction of the strong electron-withdrawing nitro group between the side arms on the central ring leads to a B7 phase. Compounds possessing a bromine atom or two chlorine atoms in the neighbourhood of the ester groups form LC phases typical for rod-like molecules, namely a nematic – smectic phase sequence. The results are compared with those reported for the azobenzoyl analogues.

We provide experimental evidence that photoalignment at the nematic liquid crystal (NLC)-polymer interface cannot be simply considered as a two-dimensional process. Moreover, our experiments clearly indicate that the photoaligning process does not depend on the individual properties of the NLC material and those of the interfacing polymer exclusively. The polymer and the NLC layer interact, i.e., the polymer-liquid crystal interface should be regarded as a coupled system, where the two components mutually influence each other. Furthermore, we show that the temperature induced anchoring transition also has to be taken into account for the complete description of the photoalignment mechanism.

Optimal water supply of plants is key to high yields. However, irrigation in drier regions must be accompanied by soil conservation. Nationwide planning of irrigation needs spatially exhaustive, functional soil maps, which may support proper recommendations for the different areas. For supporting the Hungarian national irrigation strategy, a series of countrywide functional soil maps was created, which reveal the pedological constraints, conditions and circumstances of irrigation by the spatial modelling of the relevant functional features of the soil mantle. Irrigation can improve productivity, while its negative effects may lead to soil degradation. This paper focuses on threats, the spatial identification of potentially affected areas. The thematic maps spatially model the irrigability and vulnerability of soils. Estimation of salt accumulation hazard, and soil structure degradation risks were targeted. The salinization hazard assessment was carried out by two ways. We applied the steady state concept of critical water-table depth and a more dynamic, process-based method. To estimate soil structural degradation hazard, class-based relationships were developed based on soil profile data of MARTHA 1.0 (Hungarian Detailed Soil Hydraulic Database). Soil type, organic matter content, carbonate content, soil reaction and texture class (USDA) were taken into consideration to develop pedotransfer functions for modelling the correlations between primary soil properties and threats indicators. The new maps can help decision makers to improve land use management, and sustainable agronomy.

Az a meglátásom, hogy sajnos elég sok elfogult, valamely szempontból prekoncepciós „elemzés” létezik és születik a témában, melyek számításában jelentős hiányosságokra utaló eredmények is szerepelnek. Mindez alkalmas az arra fogékony érdeklődőket félrevezetni, gondolataiban összezavarni, esetleg irányítani. Mert könnyebb az érdemi kritikai értékelésnél egy hivatkozás alkalmazása. Célom nem a meggyőzés és az irány megjelölése, inkább ellenkezőleg, a szükséges mértékű elbizonytalanítás, az elmélkedésre ösztönzés, hogy próbáljuk meg több szempontból is megvizsgálni a címbeli, korunkban egyre inkább divat- és üzletijelleget öltő témakört.Ezt szolgálják a kérdések és a kérdésekben megfogalmazódó következtetések sora is. Több szem többet lát, ha kinyitják, talán a veszélyekből és a lehetőségekből egyaránt.

When choosing the topic, I tried to focus on dealing with such a current and ongoing event, we still don’t see the result, and I just find where it develops in three, five, or ten years. Digitization affects all segments and industries to varying degrees, and its impact can be widely demonstrated. Besides, the precarious economic situation resulting from the COVID-19 epidemic further complicates the situation. I found the topic relevant because I am dealing with a phenomenon, a dilemma that directly or indirectly affects everyone and can be useful to a wider audience. During the dissertation, I try to answer the following questions: How does COVID-19 affect the process of digital transformation in the Hungarian banking sector? And how does this affect the collaboration strategies of banks and FinTech companies? In my work, I rely mainly on previous publications and articles by international, prominent researchers. Also, I conducted interviews with Hungarian experts who are currently actively working for Hungarian banks. During the selection of the interviewees, I followed the concept of asking the employees of different financial institutions working at different levels for the most comprehensive picture. In terms of methodology, in addition to processing the interviews and evaluating the literature, I tried to collect and analyze surveys and public data from various commercial banks, regulatory bodies, and major consulting firms. In this article, I have collected trends that have influenced the current state of the banking sector and present the operating environment. In addition to the positive and negative factors influencing the relationship between domestic commercial banks and FinTech companies, I outline a possible scenario for a future digitization strategy for the banking sector. This exploratory research aims to examine the situation and to identify the most important variables and correlations.

Recently, FAO and Global Soil Partnership (GSP) launched the Global Map of Salt-affected Soils (GSSmap) international initiative, which pursued a country-driven approach and aimed to update the global and country-level information on salt-affected soils (SAS). The objective of our study is to present how Hungary contributed to this international initiative by preparing its own SAS maps according to the GSSmap specifications. For this purpose, we used not just a combination of advanced machine learning and multivariate geostatistical techniques for predicting the spatial distribution of the selected SAS indicators (i.e., pH, electrical conductivity and exchangeable sodium percentage) for the topsoil (0–30 cm) and for the subsoil (30–100 cm), but also a number of image indices exploiting a huge amount of relevant information contained in Sentinel-2 satellite images. The importance plots of random forests showed that in addition to climatic, geomorphometric parameters and legacy soil information, image indices were the most important covariates. The performance of spatial modelling of SAS indicators was checked by 10-fold cross validation showing that the accuracy of the SAS maps was acceptable. By this study and by the resulting maps of it, we not just contributed to GSSmap, but also renewed the SAS mapping methodology in Hungary, where we paid special attention to modelling and quantifying the prediction uncertainty that had not been quantified or even taken into consideration earlier. Acknowledgment: Our research was supported by the Hungarian National Research, Development and Innovation Office (NKFIH; K-131820 and K-124290) and by the Premium Postdoctoral Scholarship of the Hungarian Academy of Sciences (PREMIUM-2019-390) (Gábor Szatmári).

Little is known about the suite of ecological conditions under which characteristic species may continue to develop under the pressure of recent habitat deterioration. We aimed to determine the niche of three indicator species of the priority habitat Pannonic salt steppes and to find out how their vegetation composition, land use, and soil chemistry mirror the current condition of their typical habitat. A plot-based vegetation survey was conducted in degraded and in pristine (reference) inland salt steppes in East-Central Europe. We confirmed decreased habitat quality at their northern geographical limit. Most of the sites there showed a strong prevalence of generalists (e.g., Elytrigia repens) and lack of specialists, both resulting from lowered habitat extremity and inappropriate land use (abandonment). A small proportion of plots (19%) were in the same good condition as the reference vegetation in the central area. Soil analyses revealed that the studied halophytes are able to persist on desalinized soils if the land use is suitable. The occurrence of the annual Camphorosma annua (Amaranthaceae) was driven largely by abiotic stress, grazing alone is insufficient for its long-term persistence, while the perennial Artemisia santonicum (Asteraceae) and Tripolium pannonicum (Asteraceae) have higher survival chances as they are able to coexist with generalists. Overall habitat quality can be reliably determined from the analyzed ecological conditions of indicator species. The outcomes of the presented work are relevant for conservation practice and can serve as a quick tool for assessing the current stage of other grassland habitats.

Background Saline-sodic lands threaten the food supply and ecological security in the western Songnen Plain of northeast China, and the gypsum is commonly adopted for restoration. However, the dynamics of soil bacterial community and the correlation with crop yield during restoring processes remain poorly understood. Here, we elucidated the soil chemical properties and bacterial communities and their associations with rice yield under different flue gas desulphurization gypsum (FGDG) application rates combined with brackish ice leaching. Results The increased application rate of FGDG generally improved soil reclamation effects, as indicated by soil chemical properties, bacterial diversity, and rice yield. Compared with fresh ice irrigation, the rice yield in brackish ice treatment increased by 15.84%, and the soil alkalinity and sodium adsorption ratio (SAR) decreased by 35.19% and 10.30%, respectively. The bacterial alpha diversity significantly correlated and predicted rice yield as early as brackish ice melt, suggesting the bacterial diversity was a sensitive indicator in predicting rice yield. Meanwhile, the bacterial communities in the control possessed a high abundance of oligotrophic Firmicutes, while eutrophic bacterial taxa (e.g. Proteobacteria) were enriched after brackish water irrigation and FGDG application. Moreover, we also established a Random Forest model and identified a bacterial consortium that explained an 80.0% variance of rice yield. Conclusion Together, our results highlight the reclaiming effect of brackish ice in the saline-sodic field and demonstrate the sensitivity and importance of the soil bacterial community in predicting crop yield, which would provide essential knowledge on the soil quality indication and bio-fertilizer development for soil reclamation. © 2021 Society of Chemical Industry.

We demonstrate experimentally that the anchoring of a nematic liquid crystal on a solid substrate together with the anchoring of the liquid crystal on a nanoparticle surface induces orientational self-assembly of anisometric nanoparticles in liquid crystal droplets. The observed phenomenon opens a novel route for fabrication of thin colloidal films with tailored properties.

A new liquid crystal dimer, 1,12-bis(4-(2-(4-nitrophenyl)ethenyl)phenoxy)dodecane, was synthesized and structurally characterized. The compound exhibited enantiotropic nematic phase. The spectroscopic properties were analysed by UV–Vis and fluorescence techniques. Theoretical calculations were used to predict the UV–Vis spectral properties of three isomers and propose a mechanism of conversion between them. The obtained results present a solid basis for the future studies on the stilbene-based liquid crystal dimers, thus affording guidelines for development of a structure–property relationship of these compounds.
