Authors: Velišek Otilia J 
Published: March 2022

U radu se istražuju profesionalna uverenja vaspitača i njihova povezanost i usklađenost sa osnovnim teorijskim postulatima koncepta novih Osnova programa prdškolskog vaspitanja i obrazovanja Godine uzleta (2018). Cilj istraživanja je da se utvrdi u kojoj meri su usklađena i povezana uverenja vaspitača i budućih vaspitača (studenata) sa postulatima novih Osnova programa, kao i na koji način oni razumeju određene postulate iznete u ovom zvaničnom dokumentu. Korišćen je metod deskriptivne analize, sa ciljem da se napravi precizan pregled stanja predmeta istraživanja. Kombinovane su tehnike skaliranja i fokus grupe. Uzorak je prigodan, te i rezultati imaju sve osobine i ograničenja karakteristična za ovako odabrani uzorak. Rezultati istraživanja pokazuju da kod vaspitača obuhvaćenih uzorkom istraživanja postoji veliki stepen slaganja sa tvrdnjama iz zvaničnog programskog dokumenta, ali takođe ukazuju na potrebu da se posveti više pažnje izgrađivanju slike o detetu i detinjstvu, koja će biti u većoj meri usklađena sa teorijsko vrednosnim postulatima Osnova programa, sa razumevanjem deteta kao kompetentnog i bogatog potencijalima i razvijajućim kapacitetima koji ga čine aktivnim učesnikom sopstvenog razvoja. Podaci dobijeni na prigodnom uzorku ipak mogu da ukažu na neke pravce za unapređivanje i osavremenjavanje inicijalnog obrazovanja vaspitača, kao i programa stručnog usavršavanja vaspitača.

Neverbalna komunikacija podrazumeva sve načine ponašanja bez upotrebe reči koji se dešavaju svesno ili nesvesno. Takođe, predstavlja jedan od vodećih aspekata kada je u pitanju proučavanje uspeha u učenju učenika i studenata. Cilj ovog rada bio je da se identifikuju neverbalni znaci korišćeni u učionici kao i da se utvrdi da li razlike u polu, godinama i proseku u toku studija utiču na vrednovanje značaja neverbalne komunikacije u učionici. Istraživanje je obuhvatilo 131. osobu, svi su bili studenti Zdravstvene nege Medicinskog fakulteta u Novom Sadu. Korišćen je Upitnik za procenu neverbalne komunikacije i sociodemografski upitnik konstruisan u svrhe ovog istraživanja. Rezultatima je utvrđeno da studenti visoko vrednuju značaj neverbalne komunikacije u edukaciji, kao i da ne postoje statistički značajne razlike u odnosu na pol, uzrast i ostvaren prosek u toku studija kada je u pitanju vrednovanje značaja neverbalne komunikacije u nastavi. Na osnovu istraživanja može se zaključiti da je neverbalna komunikacija od vrlo visokog značaja kako u edukaciji tako i u svakodnevnim interakcijama i kao takva trebalo bi da predstavlja jednu od najvažnijih stavki proučavanja kada je u pitanju edukacija studenata.

Published: March 2022

This paper discusses the application of a new nature-inspired optimization algorithm, called Whale Optimization Algorithm (WOA), to the resolution and optimization of single- and multi-objective problems in microelectronic design field. The performances of WOA are tested on one of the more interesting analog integrated circuits (ICs), for low supply voltage applications, the low-voltage amplifier (LVA). After identifying and determining the constraints of the LVA circuit, WOA is used to optimize MOS transistors sizes. This allows the best gain, the largest bandwidth and the highest slew rate. These main characteristics are optimized in two ways. In the first step, each function is optimized on its own, keeping the others fixed. In the second, the three characteristics are combined, with equal weights, to form a single main objective function. WOA is coded in MATLAB and the obtained results are confifirmed by Cadence Virtuoso simulations in CMOS 0.18µm technology. The simulation results are 88.8dB (88.73dB), 23.92V/µs (20.52V/µs) and 24.6MHz (25.5MHz) for DC gain, slew rate and gain bandwidth in the single (multi)-objective experiment, respectively, justifying that WOA is an effective method for the design of the above mentioned circuit.

Published: March 2022

Abstract
This work focused on the effects of chitosan (CS) and 9,10-dihydro-9-oxo-10-phosphaphenanthrene-10-oxide (DOPO) on the flammable properties of epoxy resin matrix. The EP composites were fabricated by direct mixing method following a general curing method. The influence of CS, DOPO and CS / DOPO on the resin was investigated through cone calorimetry tests (CC), UL-94 vertical burning, limiting oxygen index (LOI), thermal gravimetric analyzer (TGA), differential scanning calorimeter (DSC) and thermogravimetric analyzer-Fourier infrared combined system (TG-FTIR). The char residues of the modified EPs after CC tests were investigated by FTIR, EDX and XPS. Under the 10% addition of CS/DOPO with the mass ratio of CS and DOPO of 1 : 1, 1 : 2, 1 : 3, 2 : 1 and 3 : 1 in EP, the flame retardancy of the all EPs increased, but only EP/10% CS1/DOPO2 and EP/10% CS2/DOPO1 achieved a V-0 rating and their values of LOI were 33.7% and 32.5%, respectively. Compared with EP, the peak heat release rate, peak smoke produce rate and total heat release of EP/10% CS1/DOPO2 and EP/10% CS2/DOPO1 decreased, especially, total smoke release decreased by 61.9% and 71.0%, the char residuals amount increased by 84.3% and 41.6%, and the average CO2 yield decreased by 55.4% and 55.0%, respectively. It is worth nothing that the mechanical properties were improved, especially the flexural strength increased by 36.0% and 38.4%, respectively. The results indicated that DOPO and CS had important synergistic effects for simultaneous increase both the flame retardancy and mechanical properties of EP composites.

Published: March 2022

Abstract
Introduction: Current estimates of pandemic spread using infectious disease models in Germany for SARS-CoV-2 often do not use age-specific infection parameters and are not always based on known contact matrices of the population. They also do not usually include setting-based information of reported cases and do not account for age-specific underdetection of reported cases. Here, we report likely pandemic spread using an age-structured model to understand the age- and setting-specific contribution of contacts to transmission during all phases of the COVID-19 pandemic in Germany.Methods: We developed a deterministic SEIRS model using a pre-pandemic contact matrix. The model is optimized to fit reported age-specific SARS-CoV-2 incidences from the Robert Koch Institute, includes information on setting-specific reported cases in schools and integrates age and pandemic period-specific parameters for underdetection of reported cases deduced from a large population-based seroprevalence study. Results: We showed that taking underreporting into account, younger adults and teenagers are the main contributors to infections during the first three pandemic waves in Germany. Overall, the contribution of contacts in schools to the total cases in the population was below 10% during the third wave. Discussion: Accounting for the pandemic phase and age-specific underreporting seems important to correctly identify those parts of the population where quarantine, testing, vaccination, and contact-reduction measures are likely to be most effective and efficient. In the future, we will aim to compare current model estimates with currently emerging during-pandemic age-specific contact survey data.

Published: March 2022

Abstract
An isolate of Streptomyces decoyicus was identified by the sequencing of 16S rRNA gene. It was grown on solid media (250 ml) and secondary metabolites were extracted with n-butanol (100 ml). The extract was dried and run in a sodium dodecyl sulphate-polyacrylamide gel (SDS-PAGE, 10%). Two main bands obtained were sliced and the metabolites were regained in n-butanol (100µl). These two samples were then identified by gas-chromatography-mass spectrometry (GC-MS), and Fourier-transform infrared spectroscopy (FT-IR). The results demonstrated that tromethamine- and 1-dodecanol were the main constituents (band 1: 61% and 17.7%; band 2: 41% and 54%, respectively). This finding maintained that the isolate of Streptomyces decoyicus produced high amounts tromethamine- and 1-dodecanol-like compounds under the conditions investigated.

Abstract
SARS-CoV-2 variants with spike (S)-protein D614G mutations now predominate globally and increase infectivity by assembling more functional S protein into the virion. In this paper, I combine topology geometric methods for the generation of novel drug designs by using generalized k - nearest neighbors as a Tipping–Ogilvie and Machine Learning application within a quantum computing chemical context targeting in a atomistic level the S proteins with aspartic acid (SD614) and glycine (SG614) at residue 614 protein apparatus.

Published: March 2022

Abstract
Background and objectivesVisual impairment and dementia both increase with age, and it is likely that many older people will suffer from both conditions. This scoping review aims to investigate the prevalence and types of visual impairment among older people with dementia, and the impact of visual impairment on older people with dementia and their carers. MethodsThis scoping review used Arksey and O’Malley’s methodological framework. Studies in any setting involving people with dementia and some assessment of either visual impairment, eye diseases causing visual impairment or the impact of visual impairment were included.Results Thirty-one studies investigating the prevalence of visual impairment among older people with dementia were included with estimates ranging from 19.7% to 51.6%. Only ten studies reported on impacts of visual impairment on older people with dementia, including increased use of hospital services, increased disability and dependency, reduced social engagement, negative emotions, increased abnormal behaviours, loss of hobbies, difficulty in using visual aids or memory aids, and greater Neuropsychiatric Inventory symptoms. Only one study reported on impacts on carers and found increased conflict and physical exhaustion.Conclusion Visual impairment is common in older people with dementia and is associated with negative impacts on those with dementia and their carers. However, heterogeneity between studies in terms of setting and method for assessing VI make it difficult to compare findings between studies and further research is needed, particularly assessing the impact on carers.

Abstract
BACKGROUND
Some authors have reported that angiotensin converter enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARB) improve clinical outcomes in hypertensive COVID-19 patients, and others have proposed cross-protection for influenza vaccination. The impact of these variables on the evolution of hospitalized patients, focusing in the first wave and the Delta wave, is explored.
METHODS
COVID-19 hospitalizations (n = 1888) of the assigned population, from March 1, 2020, to July 31, 2021, in the Hospital of Terrassa, the referral center for the free access Terrassa Health Consortium in the North Metropolitan Barcelona Health Region (population = 167,386) were studied. The number of chronic treatments and conditions in a sample of patients from the first (n = 184) and Delta outbreak (n = 158) were recorded.
RESULTS
Of the non-survivors, 96.3% were aged > 60 years in the first wave and 100% were aged > 70 years in the Delta wave. In non-survival hospitalized patients aged > 60 years, the percentage treated with ACEI was similar to general population but was significantly different for ARB treatments or influenza vaccination, although associated to a higher comorbidity and age. In July 2021, the number of hospitalizations for patients aged < 50 years was higher than March 2020 and 22% of hospitalized patients without chronic treatments and conditions needed admission to the intensive care unit. Mortality was reduced in the groups with most comorbidities who received influenza and SARS-CoV2 vaccination.
CONCLUSIONS
In COVID-19 infection, age and comorbidity are related to survival, ACEI use is safe. A high proportion of patients without comorbidity require hospitalization and intensive care.

Abstract
Originating from Japan, the red macroalga Agarophyton vermiculophyllum colonizes saltmarshes from Europe and is invasive in mudflats from Brittany (France) where it creates a novel habitat with a high associated animal diversity. In Brittany, its particularity to bury in the mud, led us to wonder whether the buried fragments were still alive or just detritus. The seasonal phenology of buried fragments was monitored, together with the physiological state of fragments using Imaging-PAM fluorometry and respiration measurements. In parallel, metabolomic analyses allowed the analyses of the major intracellular metabolites. At depth in the mud, siltation is responsible for a fragmentation of the thallus and biochemical variations. A strong increase of antheraxanthin and zeaxanthin, chlorophyll-a and β-carotene was noticed while the R-Phycorythrine decreased. For osmolytes, we noted an alanine increase with siltation while floridoside decreased. No variation was noticed for isethionic acid and taurine. The C/N ratio was higher at the silt surface and decreased with siltation. Finally, The fragments are physiologically active; they present functional photosystems II and therefore do not consist of detrital material. Our study shows the ability of thalli to live in the mud to a depth of 12 cm. Fragmentation of the thallus is probably due to grazing intensity and bioturbation activity. Finally, the existence of small viable fragments deep in the mud, may represent a reserve biomass and considerably favors the propagation of Agarophyton vermiculophyllum, on the same site but may also allow a migration of the species through sediment transport.

Published: March 2022

Abstract
Recent work looks at the role of green faith in shifting green buying strategies, green perceived risk and green perceived efficiency. The role of moderator in the study is environmental awareness. The goal of the study is to detect how green trust, green perceived risk and green quality affect green buying intent. Interesting results have been reported through analyses of a sample of 306 consumers from many energy saver markets in Pakistan. Preacher and Hayes analysis of the study performed an experiment of analysis. The prediction of the green purchasing intention showed substantial green confidence, green perceived danger and green perceived price. In addition, environmental understanding greatly mitigated predictor-dependent variable relations. Product wise examination of current model adds new directions and findings to the future. Former studies on green purchase intentions have predominantly fixated on simple models at any given time. However, researchers increasingly claim that a complex demonstration may give better understanding of customers’ green purchase intention. To the best of authors’ knowledge, this study is one of the first studies to discourse a complex structure of proposed variables.

Published: March 2022

Abstract
Background
Immunotherapy has been proved its gigiantic influence in extensive-stage small cell lung cancer (ES-SCLC), however, the role of immunotherapy in limited-stage small cell lung cancer (LS-SCLC) is still unkonwn.
Methods
A retrospective study of 6 patients with LS-SCLC who were treated with neoadjuvant chemoimmunotherapy (durvalumab plus etoposide combined with cisplatin) was performed. Patients were evaluated by the safety, feasibility and pathologic responses of neoadjuvant chemoimmunotherapy.
Results
Neoadjuvant chemoimmunotherapy was associated with few immediate adverse events and did not delay planned surgery. All patients achieved partial pathologic response (pPR) instead of major pathologic response (mPR) or pathologic complete response (PCR). No association was observed between programmed death-ligand 1 (PD-L1) expression in tumor specimens and the pathologic response. However, tumors with high expression of FoxP3 + regulatory T cells (Tregs) had a better pathologic response than tumors with low expression of FoxP3 + Tregs (Pearson’s r = 0.7280; P = 0.04).
Conclusions
Neoadjuvant chemoimmunotherapy achieved pPR with few side effects in all resected tumors with LS-SCLC. The FoxP3 + Tregs in tumor microenvironment might play an important role in the chemoimmunotherapy in LS-SCLC.

Abstract
The objective of the work is to investigate the single slope solar still for the enhancement in productivity by the inclusion of optimum weight of palm flower powder of micro-sized in the absorber basin and optimum weight% of micro-Phase Change Material (mPCM) under the absorber basin. In this regard, the effect of different weights of palm flower powder such as 10, 30, 45, 50, 55, 70, 100, 120 and 150 g in the absorber was analysed. The solar still with 50 g of palm flower powder in the absorber increased the productivity by 37.25% whereas, for 10, 30, 45, 55, 70, 100, 120 and 150 g were 11.85, 24.78, 36.1, 36.8, 34.35, 33.05, 10.25 and -20.22% respectively. The effect of different weight% of micro-sized palm flower powder such as 5, 10, 15 and 20 wt%, in paraffin wax, was investigated. The paraffin wax with 20 wt% of micro-sized palm flower powder has a better thermal conductivity of 0.33 W/mK. The experimentation was carried out with 50 g of micro-sized palm flower powder in the absorber basin and 20 wt% mPCM under the absorber basin solar still (PCMPFP-SS) and Conventional Solar Still (CSS). The overall yield of PCMPFP-SS was 4670 ml/m2-day on day 1 and 4250 ml/m2-day on day 2, for CSS it was 3030 ml/m2-day on day 1 and 2800 ml/m2-day on day 2. It was evaluated that the Cost per Litre of PCMPFP-SS was $ 0.025 and $ 0.032 for CSS.

Published: March 2022

Abstract
Cellulose nanostructures and composite membranes incorporating nanoscale cellulose have gained attention due to their promising utility in various applications. Cellulose nanocomposites in the forms of aerogels, thin films, and nanopapers have been studied extensively. This review focuses on nanocomposite membranes of cellulose which find uses in desalination, sensing, electrical, and biomedical applications. The presence of abundant hydrogen bonds and easily functionalizable surfaces makes cellulose an appropriate material for the fabrication of membranes that can be leveraged for their adsorptive capabilities applicable to water treatment. Membranes of nanocellulose, their modifications by various reinforcements, augmentation of thermal stabilities, selectivity as sensors etc., are discussed in detail here along with pertinent physicochemical aspects. Regenerated cellulose which has different characteristics compared to natural cellulose, is also being discussed.
