Published: May 2021

AimThe lockdown of sports infrastructure due to the COVID-19 pandemic has substantially shifted people’s physical activity towards public green spaces. With Germany’s lockdown as one of the more severe governmentally imposed epidemic-control-decisions, we tested to what extent the frequency of outdoor cycling activities changed from March to June 2020.MethodsUser behaviour and frequency in 15 urban and 7 rural German public green spaces was quantified using cycling data from the fitness application Strava. Changes in cycling activities were analysed with four different generalised linear models, correcting for factors like weather conditions and temporal changes in the user base of the fitness application.ResultsWe found a clear increase in outdoor cycling sport activities in urban public green spaces in response to epidemic-control decisions (e.g. increase by 81% in April relative to the expected value (95% CI [48%, 110%])). In contrast, biking in rural areas showed no significant change with epidemic-control-decisions in place.ConclusionFitness App data, e.g. from Strava, can be used to monitor visitor behaviour and frequency. The increase in outdoor cycling activities during epidemic control decisions likely reflects a shift of sport activities from indoor and team sports to outdoor and individual sports. This highlights the importance of accessible green space for maintaining physical fitness and health. Beyond this shift, it is likely that outdoor activities may be of particularly importance for stress relief in times of crisis such as the current COVID-19 pandemic.

Published: May 2021

Natural rubber (NR) is an important strategic material for national defense industry. It is also used in the food industry and medicine. However, due to the unsaturated double bond, its aging resistance, mechanical properties and solvent resistance are very poor. In order to improve these properties, carbon nanotubes (CNTs) and reduced graphene oxide (rGO) were used, added at 1 : 1 ratio. TheNR/CNTs/rGO nanocomposites were obtained by mechanical mixing after adding 1, 2, 3 and 4 phr offiller. The influence of the filler content on the structure (TEM), vulcanization properties, abrasion and solvent resistance, mechanical properties, dynamic mechanical properties (DMA) and thermal properties (TGA) of nanocomposites was investigated. Increasing the content of CNTs/rGO increased the crosslinking density of the composites. TEM studies showed that CNTs and graphene sheets were evenly dispersed throughout the NR matrix. They also had good compatibility with the rubber matrix. The addition of CNTs and graphene increased the abrasion and solvent resistance as well as improved the mechanical properties. TGA analysis showed that the nanocomposites had excellent thermal stability. The best properties were obtained with the CNTs/rGO content of 2 phr.

Published: May 2021

Abstract
Circular RNAs (circRNAs) have gained much attention for their crucial regulatory roles in human diseases and cancers. However, the role and the mechanism of circRNA ArfGAP with FG repeats 1 (circAGFG1) in non-small-cell lung cancer (NSCLC) are still largely unknown. circAGFG1 was highly expressed in NSCLC, and high expression of circAGFG1 was closely related to the low survival rate of NSCLC patients. circAGFG1 knockdown inhibited the proliferation, migration, and invasion and promoted the apoptosis of NSCLC cells. circAGFG1 bound to miR-28-5p in NSCLC cells, and circAGFG1 promoted NSCLC progression partly through sponging miR-28-5p in vitro. HIF-1α was a target of miR-28-5p, and miR-28-5p overexpression-mediated influences in NSCLC cells were partly overturned by the addition of HIF-1α overexpression plasmid. circAGFG1/miR-28-5p/HIF-1α axis regulated cellular glycolytic metabolism in NSCLC cells. circAGFG1 silencing restrained the xenograft tumor growth in vivo. circAGFG1 promoted the proliferation, migration, and invasion and suppressed the apoptosis of NSCLC cells through accelerating the glycolysis via miR-28-5p/HIF-1α axis.
Stavovi studenata pedagogije o autoritetu nastavnika
Authors: Krešić Marija , Zelenika Tanja , Vekić Tina 
Published: May 2021

Autoritet je ključno profesionalno i osobno obilježje nastavnika. Nastavnik treba znati upravljati i voditi razredne i školske aktivnosti, biti stručnjak iz nastavnoga predmeta koji poučava, koristiti primjerene metode poučavanja, iskazivati razumijevanje prema svakom učeniku, a pritom imati i pozitivan utjecaj na učenike. U suvremenoj se pedagoškoj literaturi taj pojam sve rjeđe koristi. Promjene u odgoju i obrazovanju koje naglašavaju autonomiju učenika i stvaranje pogodnoga ozračja za učenje dovele su do narušavanja autoriteta nastavnika u razredu.Cilj je rada razmotriti stavove studenata pedagogije o autoritetu nastavnika u suvremenom pristupu odgoju i obrazovanju, otkriti njegove karakteristike i eventualne promjene tradicionalnoga shvaćanja autoriteta. U istraživanju su sudjelovali studenti pedagogije, a provedeno je upitnikom otvorenoga tipa u kojemu su studenti iskazivali mišljenje o autoritetu nastavnika u učionici, obilježjima i značenju autoriteta. Rezultati su pokazali da studenti pedagogije autoritet nastavnika povezuju s tradicionalnim oblikom autoriteta, dajući mu obilježja relacijskoga autoriteta, tj. u velikoj ga mjeri povezuju s odnosom nastavnika i učenika.
Vrijednost aktivnosti kao element sudjelovanja u nastavnim aktivnostima Prirode i društva kod učenika razredne nastave
Authors: Beroš Ivan , Pongračić Luka 
Published: May 2021

Motivacija učenika za sudjelovanje u nastavnim aktivnostima predstavlja jedan od elemenata uspješne i kvalitetne nastave. Nastavnici su tijekom povijesti učenike nastojali motivirati na različite načine: strahom od kazne, prisilom ili razvijanjem interesa. Suvremeni pristupi naglasak stavljaju na intrinzičnu motivaciju, preciznije interes kao pokretač aktivnosti učenika na nastavi. U radu se prikazuju rezultati istraživanja kojim se nastojala utvrditi vrijednost aktivnosti kao element sudjelovanja na nastavi Prirode i društva kod učenika razredne nastave. Kao teorijska osnova korištena je teorija motivacije očekivane vrijednosti (EVT) koja analizira vrijednost aktivnosti pojedinca prema četirima komponentama: interes ili uživanje u aktivnosti, percipiranu važnost uspješnosti u aktivnosti, percipiranu korisnost te cijenu aktivnosti. Anketirano je 246 učenika drugih, trećih i četvrtih razreda dviju ruralnih osnovnih škola, a za prikupljanje podataka korišten je modificirani upitnik Motivated strategies for learning questionnaire (Pintrich i sur., 1991). Rezultati istraživanja navode na nekoliko zaključaka. Ispitanici sudjelovanju u aktivnostima na nastavi Prirode i društva pridaju visoku vrijednost bez obzira na spol i dob. Nisu utvrđene razlike u rezultatima uvjetovane dobi ili spolom ispitanika u ni jednoj od triju ispitivanih komponenata vrijednosti aktivnosti kao elementa sudjelovanja u nastavnim aktivnostima: interesu ili uživanju u aktivnosti, percipiranoj važnosti uspješnosti u aktivnosti te percipiranoj korisnosti aktivnosti za ostvarenje kratkoročnih i dugoročnih ciljeva učenika.
Kombinirani razredni odjel: socioekonomska nužnost ili pedagoški izbor?
Authors: Varga Rahela , Sabljak Matea 
Published: May 2021

Na globalnoj se razini povećava broj osnovnih škola u kojima se nastava odvija istovremeno s učenicima dvaju ili više razreda u tzv. kombiniranom razrednom odjelu. Glavni je razlog organiziranja takve forme odgoja i obrazovanja nedovoljan broj učenika za uspostavljanje klasičnoga razreda koji čine učenici istog godišta. Premda je uzrok njegova uvođenja nedostatak povoljnijih društvenih i gospodarskih uvjeta, moguće je u njemu prepoznati određene odgojne dobrobiti za učenike. Odgovor na pitanje je li formiranje kombiniranoga odjela socioekonomska nužnost, ili bi pak trebao postati namjeran odabir kompetentnoga učitelja zbog dobrobiti koje ima za učenike, ovisit će o tome stoje li u fokusu prednosti ili nedostatci kombiniranoga razrednog odjela. Cilj je bio ispitati spremnost prihvaćanja zaposlenja u kombiniranom razrednom odjelu u odnosu na razvijenost kompetencija. Rezultati su pokazali kako najveći broj sudionika istraživanja ne bi želio raditi u kombiniranom razrednom odjelu, posebice ne na početku svoje karijere jer rad u takvim uvjetima procjenjuju zahtjevnijim. Pozitivnije viđenje kvalitete nastave u kombiniranom razrednom odjelu imali su sudionici istraživanja koji su i sami bili učenici kombiniranoga razrednog odjela. Zaključuje se da je među sudionicima istraživanja kombinirani odjel dominantno procijenjen kaosocioekonomska nužnost, a ne kao pedagoški izbor.
Mogućnosti inkluzije slijepih i slabovidnih učenika u redovitu školu u Sloveniji - primjer dobre prakse
Authors: Marin Jelka 
Published: May 2021

Inkluzija je proces u kojem redovne osnovne škole i socijalno okruženje smanjuju prepreke za djecu s posebnim potrebama, što omogućava ravnopravno sudjelovanje sve djece u obrazovnom procesu. Područje obrazovanja djece i adolescenata s posebnim potrebama u Sloveniji pretrpjelo je velike promjene u posljednjih 20 godina. Zakonodavstvo usvojeno 2000. godine (Zakon o usmerjanju otrok s posebnimi potrebami, 2000) utvrdilo je uključivanje kao osnovno načelo u ovom području. Sukladno tome, povećava se broj djece i adolescenata s posebnim potrebama koji su uključeni u uobičajene oblike obrazovanja, također slijepih i slabovidnih. Osim toga, još uvijek postoje posebne obrazovne ustanove koje provode programe prilagođene djeci i adolescentima s posebnim potrebama. Inkluzija nije samo činjenica da je u učionicu ušao novi učenik koji je drugačiji i treba mu više pažnje. Umjesto toga, mora postojati pažljivo isplaniran projekt koji omogućava učenicima s posebnim potrebama da se integriraju u redovno obrazovanje. Uključivanje mora biti planirano i pripremljeno. Prije nekoliko godina učenica oštećenog vida bila je uključena u prvi razred naše škole. To je bio prvi primjer uključivanja djeteta s ovom vrstom deficita, prepreke ili poremećaja u našu školu. Za sve je stručne djelatnike u školi to bio značajan izazov, također prožet neizvjesnošću i strahom od nepoznatog. Inkluzija u Sloveniji osigurana je obrazovnim programom s prilagođenom provedbom i dodatnom stručnom pomoći, koji se provodi u svim osnovnim školama. Članak predstavlja praktični primjer uključivanja slabovidne učenice u redovnu osnovnu školu.

Objective
Hyponatremia is the most common electrolyte disorder in hospitalized patients and occurs in about 30% of patients with pneumonia. Hyponatremia has been associated with a worse outcome in several pathologic conditions The main objective of this study was to determine whether serum sodium alterations may be independent predictors of the outcome of hospitalized COVID-19 patients.

Design and methods
In this observational study, data from 441 laboratory-confirmed COVID-19 patients admitted to a University Hospital were collected. After excluding 61 patients (no serum sodium at admission available, saline solution infusion before sodium assessment, transfer from another hospital), data from 380 patients were analyzed.

Results
274 (72.1%) patients had normonatremia at admission, 87 (22.9%) patients had hyponatremia and 19 (5%) patients had hypernatremia. We found an inverse correlation between serum sodium and IL-6, whereas a direct correlation between serum sodium and PaO2/FiO2 ratio was observed. Patients with hyponatremia had a higher prevalence of non-invasive ventilation and ICU transfer than those with normonatremia or hypernatremia. Hyponatremia was an independent predictor of in-hospital mortality (2.7-fold increase vs normonatremia) and each mEq/L of serum sodium reduction was associated with a 14.4% increased risk of death.

Conclusions
These results suggest that serum sodium at admission may be considered as an early prognostic marker of disease severity in hospitalized COVID-19 patients.

Authors: Supardi Moh - , Irma Siska - 
Published: May 2021

Artikel ini bertujuan untuk menjelaskan program pengabdian kepada masyarakat yang dilakukan oleh 18 mahasiswa KKN kelompok 113 di Desa Rawa Rengas, Tangerang, Banten, pada tahun 2019. Sebelum pelaksanaan KKN, mahasiswa diwajibkan untuk melakukan survei terlebih dahulu agar program yang dilaksanakan nantinya sesuai dengan kebutuhan dan kondisi masyarakatnya. Hal ini menjadi penting mengingat kegiatan KKN yang tidak direncanakan dengan baik maka hasilnya juga akan kurang baik. Metode yang dilakukan oleh mahasiswa untuk mengumpulkan data adalah dengan menggunakan pengamatan langsung atau Particatory Rural Apraisal (PRA), wawancara, dan studi dokumen. Berdasarkan pengumpulan data dan hasil analisis data, dapat dilaporkan bahwa ada beberapa hal yang menjadi persoalan penting untuk dicarikan solusi secara bersama-sama, khususnya oleh pemerintah setempat atau aparat desa Rawa Rengas, seperti masalah lingkungan, kebersihan, pendidikan, keamanan, dan keagamaan. Masalah yang paling mudah diamati secara langsung (observasi) adalah masalah kebersihan lingkungan, seperti kali yang kotor serta sampah yang dibuang sembarangan. Sedangkan untuk masalah pendidikan, keamanan, dan keagamaan bisa diketahui melalui wawancara dengan masyarakat di desa tersebut. Kesimpulan dari penelitian ini adalah kesadaran masyarakat di Desa Rawa Rengas masih sangat rendah sehingga perlu adanya upaya dari pemerintah setempat untuk mengajak warganya agar menjaga lingkungan yang bersih dan sehat. Artikel ini diharapkan dapat memberikan gambaran umum dan menjadi inspirasi bagi para pembaca, khususnya pemerintah terkait, agar bisa bersama-sama mewujudkan lingkungan yang bersih, memiliki kesadaran dan kepedulian terhadap lingkungan sekitarnya
A review of the antimicrobial and immune-modulatory properties of the gut microbiota-derived short chain fatty acid propionate – What is new?
Authors: Langfeld Luis Q. , Du Ke , Bereswill Stefan , Heimesaat Markus M. 
Published: May 2021

AbstractAs antimicrobial resistance poses a globally rising health problem, the identification of alternative antimicrobial agents is urgently required. The short chain fatty acid propionate which is physiologically produced by the gut microbiota constitutes a promising molecule given that it has been widely used as a cosmetics and food preservative due to its antimicrobial effects. This literature survey aims to determine the most recent state of knowledge about the antimicrobial and immune-modulatory properties of propionate. Both in vitro and in vivo studies published between 2011 and 2020 confirmed the ability of propionate to inhibit the growth of several cellular pathogens, including Gram-positive and Gram-negative multi-drug resistant bacteria and fungi. In addition, heterogenous immune-modulatory and in particular, anti-inflammatory effects of propionate could be assessed involving a diverse signaling network that needs further comprehension. In conclusion, our literature survey provides evidence that propionate displays a plethora of health-beneficial including antimicrobial and immune-modulatory effects. Future research is required to further unravel the underlying molecular mechanisms and to set the basis for in vivo infection and clinical studies to broaden the path of propionate as a promising adjunct antibiotics-independent option in the combat of infections caused by multi-drug resistant bacteria.
