Határmenti ifjúság gazdasági és társadalmi viszonyulása a térséghez
Authors: Ludescher Gabriella 
Published: December 2021

A tanulmány Kelet-közép Európa három országának – Lengyelország, Ukrajna és Magyarország – egy-egy határmenti megyéjének ifjúságát (17-19 éves) kutatja. A kutatás hipotézise, hogy az ifjúságnak a területi identitása szignifikáns összefüggésben van határontúli gazdasági, társadalmi tevékenységével. Kutatási feltételezésként fogalmazódott meg az is, hogy azok a fiatalok értékelik a viszonyulásukat a szomszédos nemzetekkel „nagyon pozitívan”, akik gyakrabban utaznak külföldre, vagy/és rokoni kapcsolat fűzi ahhoz a nemzethez. A tanulmány a hipotéziseit a következő kérdések mentén tárgyalja:

a határmenti fiataloknak mi a véleményük a saját régiójúkban lévő lehetőségekről,
mennyire érzik erősnek a kapcsolatukat, városukkal, megyéjükkel, régiójukkal, Európával, illetve saját etnikai csoportjukkal.
Továbbá a vizsgálat tárgya az is, hogy az adott határmenti térség, milyen hatással van a megkérdezettek életére, a szomszédos országokhoz milyen kapcsolat, illetve gazdasági tevékenység fűzi a célcsoportot, valamint milyen gyakran szoktak külföldön járni és azt milyen célból teszik.

Kutatás fontos eleme volt a határmenti terület gazdasági és társadalmi hatásának mérésén túl az is, hogy a szomszédos nemzetekhez, milyen a viszonyulásuk a megkérdezetteknek. A vizsgálatra kiválasztott régiók különleges földrajzi adottságokkal rendelkező régiók, de emellett komoly gazdasági és társadalmi nehézségekkel küszködő térségek is. Ezen területek versenyképessége és jóléte egyre inkább attól függ, hogy az ott élő emberek és az ott élő vállalkozások optimálisan ki tudják-e használni valamennyi területi előnyt, mint például szomszédos ország gazdaság- és munkaerő- piacát, szolgáltatásokat, infrastruktúrát, valamint a nemzetközi kapcsolatokat. A gazdaság versenyképességének fejlődése függ más területekkel való kapcsolatok kiépítésétől. Az eddigi kutatások (Hardi, 2001) azt bizonyítják, hogy a jelenlegi vállalkozások a keleti térségben nem tudtak élni a régió elhelyezkedéséből fakadó lehetőségekkel. Ez magyarázható e térségek posztszocialista mivoltával is. Az 1990-as évektől az észak-kelet európai régiókban határmenti együttműködések kezdenek megjelenni, de a 2004-es Európai Uniós csatlakozás lehetővé teszi a vizsgált országok közül Magyarország és Lengyelország számára az áruk, a szolgáltatások és a tőke szabad mozgását. E mozgás mellett a technológia és az ötletek áramlása, valamint a határmenti kooperáció a területi fejlődés egyre fontosabb elemévé válik, megjelennek a komparatív előnyök is. A vizsgálati célcsoportként többek között azért választottuk a 17-19 éves korosztályt, mivel ők az új lehetőségekbe beleszülettek és azok a mindennapi életük részévé váltak. Remélhetőleg az elkövetkezendő tíz évben e korosztály tagjai a területi elhelyezkedésük és kapcsolataikból adódóan a határon átívelő gazdasági és társadalmi kohézió motorává válnak.

A kutatás célja: Vizsgálatunk célpontjában a Sapientia Erdélyi Magyar Tudományegyetem Marosvásárhelyi Kar hallgatóinak jólléte, pszicho-szociális jellemzői, mentális állapota és egészségmagatartása áll.
Módszerek: Vizsgálatunk eszköze egy standardizált kérdőív, melyet a 2018-2019-es tanév őszi félévében alkalmaztunk. A kérdőív az következő standardizált kérdőíveket is magába foglalta: Önértékelési Kérdőív (RSESH), Életcél Kérdőív (Purpose in Life Test – PIL), Észlelt stressz-kérdőív (Perceived Stress Scale – PSS4), Lelki egészség (General Health Questionnaire, GHQ-12). A vizsgálatban 206 hallgató vett részt a Sapientia EMTE Marosvásárhelyi Karáról.
Eredmények: Az alacsony önértékelésű hallgatók gyakrabban fogyasztanak alkoholt, mint az egészséges önértékeléssel rendelkező társaik. Azok a hallgatók fogyasztanak több alkoholt, akik több pszichés problémával rendelkeznek, mint a társaik. Az alacsonyabb önértékelésű hallgatók gyakrabban fogyasztanak alkoholt a lerészegedésig, mint a normális önértékelést mutató társaik. A testedzés védő faktornak bizonyult az egészségmagatartás tekintetében, így akik aktívan sportolnak, jobb mentális állapotnak és alacsonyabb stressz-szintnek örvendenek, mint a keveset sportoló társaik. A pszichés állapot társadalmi meghatározottságát adataink is alátámasztják.

Published: December 2021

We describe the formalization of Brzozowski and Antimirov derivative based algorithms for regular expression parsing, in the dependently typed language Agda. The formalization produces a proof that either an input string matches a given regular expression or that no matching exists. A tool for regular expression based search in the style of the well known GNU grep has been developed with the certified algorithms. Practical experiments conducted with this tool are reported.
Defining diversity in groupwork: A relational exploration
Authors: Popiel Melissa , LaRoque Sarah , Nicholas David , Kilmer Christopher , Este David , Pelech William 
Published: December 2021

One of the basic assumptions underlying all traditional definitions is that diversity is a characteristic of an individual or a group, which is a problematic to groupwork. This paper explores Phases 1 and 2 of a multi-method research project exploring groupworkers’ understandings of diversity and how their perceptions impact their approach to group processes, with implications for group practice advancement. The project consists of sequential phases following a mixed-methods design. In the initial phase, in-depth semi-structured qualitative interviews were conducted individually with 24 groupworkers. While the second phase (phase two) consisted of 4 focus groups involving theoretical and criterion sampling strategies to interview experienced therapeutically-oriented groupworkers in Western and Eastern Canada. The analysis was guided by Glaser and Strauss’s (1967) constant comparative method involving open-coding, followed by axial coding, and concluded with selective coding.
Groupworkers reported feeling overwhelmed and, in some cases, “paralyzed” by the complex diversity present in their groups. These findings suggest attention to group diversity renders it potentially more relevant and salient. We also found the levels and complexity of diversity increased as the reflection by groupworkers deepened. In keeping with the traditional aims of groupwork, attending to diversity goes beyond the group to include responses to diversity in the organizational and community contexts. Dialogue and change in organizational responses to diversity is important in the areas of organizational climate, allocation of resources, and agency policy and procedures. Accordingly, offering groupworkers and members tools to attend and navigate diversity in situ is a first step towards recognizing its presence and importance. A critical step in moving forward is to examine the nuances of diversity and move beyond thinking of diversity in terms of demographic variables.
Investigation of Additively Manufactured PEEK Modified With Glass Microballons as a Function of Density and Volume Fraction

Published: December 2021

Abstract
Low density and strong mechanical characteristics make hollow glass microballons (HGM) filled polyehteretherketone (PEEK) composites excellent for aerospace, transportation and civil applications. In this study, PEEK was filled with different densities of HGMs (low, medium, and high) and varied volume fractions (Vf) of HGMs (10%, 15%, and 20%) and exposed to different strain rates to investigate thermal, physical, energy absorption, and other physico-mechanical responses. PEEK/HGMs composites demonstrated a substantial strain rate impact, with the strain rate sensitivity factor increasing as the strain rate increased while decreasing as the filler Vf increased. The density of the composites was also shown to be inversely related to their strength properties. Incorporating high-density HGMs into the PEEK resulted in the lowest composite density so far reported while ensuring mechanical properties. Scanning electron microscopy images revealed that the HGM dispersion is uniform inside the matrix. Thermal stability of the syntactic foam was investigated by using Thermo Gravity Analysis (TGA) under inert atmosphere and oxidative environment conditions. The infusion of microspheres enhances the thermal stability of LDPEs, MDPEs, and HDPEs samples in an inert environment, with HDPEs samples being the most thermally stable. This might lead to the formation of a strong bond between polymer chains and HGM particles.

Published: December 2021

Abstract
Hepatocellular carcinoma (HCC) is a common type of cancer—prevalent worldwide—and one of the causes of cancer-related deaths. In this study, ethanol extracts from Pholiota adiposa (EPA) were used to identify possible targets for HCC treatment and their effects on intestinal microflora were analyzed. Methods: Male mice were randomly assigned to groups—the model group, cyclophosphamide (25 mg/kg/d), and EPA groups, in which the mice were categorized based on the different concentrations of each compound (100, 200, and 300 mg/kg/day). Relevant biochemical indicators were detected using ELISA, H&E staining, and TUNEL assay. Four tumor apoptosis-related proteins and genes, Caspase3, BAX, Bcl-2, and VEGF, were detected by immunohistochemical staining, western blotting, and RT-PCR. The total genomic DNA was obtained from the contents of the small intestine and colon and was sequenced. The V3+V4 regions of bacterial 16s rDNA (from 341 to 806) were amplified. Results: The tests revealed that EPA exhibited antitumor activity in vivo by promoting apoptosis and inhibiting angiogenesis. Moreover, EPA treatment could increase beneficial and decrease harmful microflorae. These results demonstrate that EPA may be a potential therapy for HCC.

Abstract
Malaria continues to be a killer disease even in the modern world. Vaccines and drugs have a lot to learn from the malaria parasite before they can be successful. Here, using a filter for glideosomal anchor protein PfGAP50, we have explored a plethora of small molecules to shortlist eight GAP50 binders with promising antiplasmodial activity (IC50 < 3 µM) that are also highly selective. Of these, Hayatinin, Bedaquiline, MMV688271, Curine, and Brilacidin with PfINDO IC50 ≤ 1 µM were found to stall merozoites invasion by inhibiting IMC formation besides increasing ROS levels in trophozoites. Bedaquiline loaded healthy RBCs showed prophylactic ability to prevent intraerythrocytic development of malaria parasite. Synergistic activities with ΣFIC values as low as 0.22 (Curine and Artemisinin) or 0.37 (Bedaquiline and Artemisinin) augur well for the development of drug combinations to combat malaria effectively. Interestingly, orally delivered Bedaquiline (50 mg/Kg b. wt.) showed substantial suppression of parasitemia in the mouse model of malaria.

Between 2015 and 2019, this study in Metehara, South east, Ethiopia. set out to investigate the temporal dynamics of genetic diversity and multiplicity as a result of evolutionary change in the genes that contribute to Plasmodium falciparum infection elimination. Method: Between 2015 and 2019, a cross-sectional study was carried out. from eighty-three dry blood spots from malaria patients who were screened for P. falciparum mono-infection by QPCR. From this seventy confirmed P. falciparum were genotyping to merozoite surface protein 1,2 and glutamate-rich protein using nested PCR.Result: Between 2015 and 2019, seventy (84.3%) of the isolates were successfully genotyped for all three target genes in both years. In 2015 and 2019, the allelic distributions of the three genes differed significantly (P= 0.001). Overall, the most common allelic families for msp1 and msp2 were K1 and FC27 respectively. For glurp, eight distinct genotypes were identified. In 2015, the genotyping of msp1, msp2 and glurp was 25 (86.2%), 25 (86.2%) and 24 (82.2%) respectively. K1, MAD20 and RO33 all have 19(65.5%), 3(10.3%) and 3(10.3%) msp1 allelic families respectively. In 2019 the genes were 30 (73.2%), 39 (95.1%) and 30 (73.2%). K1, MAD20, and RO33 were genotyped for 6 (14.6 percent), 18 (43.9 percent) and 6 (14.6 percent) genotyping respectively. Over all the multiplicity of infection was 1.67 (95 percent CI 1.54-1.74) and the heterozygosity index for msp1, msp2, and glurp was 0.48, 0.70, and 0.55 respectively.Conclusion: This study provides current information on the genetic diversity of P. falciparum populations in Metehara over five-year intervals, The progression of the dominant K1 variant from 2015 to MAD20 variant in 2019 was observed in this study.

Abstract
Background: Post-operative pain management is one of the key responsibilities of health professionals. Failure to manage post-operative pain effectively will lead to increase morbidity and mortality, long hospital stay, increase health care costs, and patient dissatisfaction. Despite improved understanding of pain mechanisms, advances in pain management approach, and other focused initiatives large proportion of post-operative patient’s reports pain after surgery. Therefore the major aim of this study was to assess pain severity and associated factors among post-operative adult patients in public hospitals of Addis Ababa.Methods and materials: A facility-based cross-sectional study was conducted. A total of 414 study participants were involved. Simple random sampling was used to select study participants. The data was collected by the standard questioner and checklist. The collected data were entered, cleaned, and analyzed by SPSS version 24.0 statistical software. Bi-variable analysis was employed to select independent predictors of pain severity and multivariable regression used to measure the association between independent and dependent variables. On bi-variable analysis, those variables with a value less than 0.20 were entered on multi-variable analysis. Finally, variables with a p-value < 0.05 were declared as independent predictors of the outcome variables.Results: A total of 406 study participants have responded to the interview giving a response rate of 98%. The overall incidence of moderate to severe pain was 85.5%. Preoperative analgesia adjusted odds ratio (confidence interval), 0.236(0.065-0.863), preoperative anxiety, 5.468(1.341-22.303), general surgery 7.627(1.901-30.602), orthopedics surgery, 7.195(1.055-49.094), size of the incision, 5.086(1.352-19.135), and postoperative analgesia; non-steroidal anti-inflammatory drugs 5.611(2.000-15.737), and tramadol, 4.714(1.506-14.753) was independent predictors of postoperative moderate to severe pain.Conclusion: The study revealed that the overall incidence of postoperative pain was high in the study area. This reflects attention given to postoperative pain management is low. Preoperative analgesia, preoperative anxiety surgery type, incision length, and postoperative analgesia were independent predictors of postoperative pain.
Evergreen Abundance Drives Ground Beetle Diversity And Density In Eastern Temperate Forests

Published: December 2021

Abstract
Purpose: Soil insects mediate plant-soil interactions by fragmenting and decomposing litter that forms the base of soil food webs and through predator-prey interactions. Plant communities, in turn, shape soil insect communities via the quality, availability, and diversity of their litters. However, these drivers have rarely been examined in concert even though describing soil insect community patterns is critical for mitigating the effects of global environmental changes. Methods: Here, we evaluated the effects of tree diversity, density, and functional groups on ground beetle (Carabidae) diversity, density, and community composition in four eastern temperate forest sites in the National Ecological Observatory Network. Results Though we expected that higher tree diversity and density would, respectively, lead to higher diversity and density ground beetle communities, we found little evidence to support this hypothesis. Instead, evergreen tree abundance strongly shaped ground beetle diversity, density, and community composition. Specifically, evergreen plots as defined by National Land Cover Database hosted lower density ground beetle communities than deciduous plots. Similarly, ground beetle Shannon diversity and density decreased as the relative abundance of evergreen tree species increased. Conclusions: Although further study is needed to explicitly link litter quality with soil insect communities, the resource environments created by trees with varying leaf habits appear to be a dominant force driving ground beetle community diversity and density patterns.
Overexpression of Chorispora bungeana CbPLDγ enhances drought tolerance in Arabidopsis
Authors: nikang  , bang  
Published: December 2021

Abstract
Phospholipase D (PLD) is a crucial enzyme participated in membrane phospholipid catabolism. In this study, to explore the function of CbPLDγ in drought stress, a CbPLDγ gene, which is a part of CbPLD gene family and from Chorispora bungeana (C. bungeana) was cloned and encoded a protein of 859 amino acids with a calculated molecular weight of 96.3 kDa and with a PI(Isoionic Point) of 7.88. Real-time quantitative PCR (RT-qPCR) and Beta-glucuronidase (GUS) assay showed that CbPLDγ was accumulated dominantly in roots and hypocotyls. Compared with the control, CbPLDγ was positively responsed to the low temperature, salt, mannitol, and exogenous ABA. Subcellular localization analysis showed that the CbPLDγ was localized in the cell membrane. CbPLDγ-overexpression Arabidopsis under drought stress showed higher relative expression of superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD), as well as highe content of proline, soluble proteion and soluble sugar. However, H2O2, malonaldehyde (MDA) content and electrolyte leakage (EL) were lower than wild-type Arabidopsis. These indicated that CbPLDγ was involved in the drought tolerance, and overexpression of CbPLDγ enhanced the drought tolerance in Arabidopsis. This is the first report about cloning and characterizing the gene of CbPLDγ from C. bungeana. It laid a foundation for further research and improvement of the PLD gene family of C. bungeana.
Using Zeolite-Zirconia-Copper Nanocomposites as a New Asphaltene Inhibitor for Improving Permeability Reduction during CO 2 Flooding
Authors: Mansouri Mohsen , Ahmadi Yaser 
Published: December 2021

Abstract
Using nanoparticles for adsorbing asphaltene was known as an efficient method among researchers for crude oil upgrading and in this study, Zeolite-zirconia-copper nanocomposites (NCs) has been synthesized and characterized with SEM, XRD, BET, and EDX for asphaltene precipitation inhibition in the static phase and solving asphaltene deposition problems of dynamic CO2 flooding in low permeability carbonate reservoir. CO2-oil IFT tests, isotherm models, natural depletion tests at static phase were performed in the presence of NCs and the results were compared with zeolite nanoparticles. Then, CO2 core flooding tests at dynamic phase were designed in the presence of NCs at obtained static conditions for surveying permeability/porosity reduction in porous media. After adding NCs and zeolite nanoparticles, the 2nd to 1st slope ratio in CO2-oil IFT tests increased from 19.697 % to 20.895 % and 29.851 %, respectively which shows NCs adsorbed more asphaltene in comparison to zeolite nanoparticles which confirmed UV-Vis results. NCs was decreased asphaltene precipitation more than zeolite at same points during natural depletion tests and it was selected for dynamic CO2 tests. After adding NCs, asphaltene depositions which occurs after CO2 injection was decreased and permeability/porosity reduction parameters were improved.
Identifying the research advances on COVID-19, the economy and the environment: network- bibliometric analysis and statistical validation
Authors: Drago Carlo , Gatto Andrea 
Published: December 2021

Abstract
The COVID-19 outbreak dictates urgent research responses. The corpus of scientific publications on COVID- 19 is rapidly growing. Differently from health and technical sciences, social and environmental sciences risk to be neglected in this process. Similarly, Environmental Economics falls behind in terms of COVID-19 scholarship. The research note in hand examines and maps up-to-date research progress on the occurring Coronavirus disease, the economy and the environment. To this end, a bibliometric analysis of these three intertwined areas is performed. We constructed a database of the key publications and extracted the keywords co-occurrence network characterising each work. Thus, we studied the structural characteristics – i.e. the density and the centre – sorting from the co-occurrence network. This exercise identifies four communities of relevant keywords, including environmental health, economic impact and lifestyle, which present the maximal mutual interconnection. It is discovered that relevant possibilities and urgency to examine the relationship between the Coronavirus, the economy and the environment exist on the issues and, broadly, in the field of Environmental Economics. The study of environmental facets and environment-economy interplay within the current Coronavirus pandemic claims a larger academic production, resulting not yet relevant and scarcely explored and signals the need to boost public and environmental health scholarship response.JEL codes: C02, I15, I18, O13, Q56
