Authors: Kaminsky Nikita S. , Gosteva Pavel R. , Mikhailova Olga G. , Ugai Sergey M. 
Published: December 2023

The lubricating properties of motor oils are of great importance for the normal operation of the crank and gas distribution mechanisms of the engine. In the cylinder-piston group, where the greatest friction forces and loads occur, as a result, the quality of engine oil directly affects the resource of the internal combustion engine (ICE). Of no less importance is the constant presence of a reliable oil film in the contact zone of the support and connecting rod necks of the crankshaft with sliding bearings. In addition to the operating time, the parameters are influenced by external environmental factors, operating conditions and the residual life of the engine at the time of oil filling. Factors affecting the operation are important for the study of oils in order to provide information about the quality of oil and the condition of the car in conjunction with these indicators. To derive oil indicators, it is required to conduct laboratory tests using special equipment in order to give more accurate information about the quality of the engine oil under study.
Purpose. Determination of the residual oil life and its effect on the mechanisms of the car engine during operation.
Method or methodology of work. The article used laboratory studies using existing instruments.
Results. The most informative parameters showing the residual resource of motor oils and their effect on the internal combustion engine are obtained.
The scope of the results. The obtained results should be used when working with vehicles that use engine oil and premature identification of cause-and-effect relationships during the repair of internal combustion engines.

EXPLORANDO SENTIDOS E CONHECIMENTOS EM VIDEOGAMES COM UMA ANÁLISE BASEADA NA GRAMÁTICA DA MULTIMODALIDADE
Authors: Silveira Silva Victor Ernesto 
Published: December 2023

Este trabalho tem como objetivo discutir a potencialidade dos videogames para o ensino e aprendizado por meio da expressão de sentidos em sua multimodalidade. Partindo de uma pesquisa qualitativa documental e utilizando um instrumento de análise de mídia fundamentado na concepção de Cope e Kalantzis (2020) sobre a gramática da multimodalidade. Esta pesquisa demonstrou por meio da investigação do jogo eletrônico Final Fantasy VII Remake, como conhecimentos sobre meio ambiente, geopolítica, organização urbana, exploração de recursos naturais e desigualdades sociais são expressos nas diversas formas e funções de sentido que constituem o jogo. A expressão destes sentidos e conhecimentos no jogo encontra respaldo nas ideias de Gee (2003) e Shaffer (2005) que defendem que os videogames são contextos que promovem o desenvolvimento de conhecimento e, portanto o aprendizado. Estas ideias também encontram eco em Bogost (2007) e Zacchi (2020) de modo que todos estes estudiosos apontam para uma revisitação o que se considera alfabetização/letramento levando-se em consideração todas as mudanças sociais promovidas pela popularização de mídias digitais e eletrônicas tal qual o videogame. Esta revisitação, portanto, se faz necessária para que haja a superação de modelos tradicionais e restritivos de espaços de ensino e aprendizado.
Unlocking Urban Insights: A Case Study on Impact of Urban Vegetation on Volatile Organic Compounds (VOCs) Variability Across Different Areas of Reggio Emilia, Italy
Authors: Marsili Vittoria , Forti Luca , Arru Laura 
Published: December 2023

The Po Valley is one of the European regions most severely affected by air pollution. Within the spectrum of airborne molecules, Volatile Organic Compounds (VOCs) represent a significant component, derived from both natural processes and anthropogenic sources. All VOCs influence air quality, as they are precursors to ozone (O3), secondary organic aerosol (SOA), and particulate matter (PM). While naturally occurring VOCs contribute to the formation of air pollutants, they also have beneficial effects on human health. Furthermore, vegetation plays a fundamental role in air purification and improvement of air quality both directly, through the metabolic processes of leaves, and indirectly, through physical mechanisms.
This study aims to evaluate the qualitative and quantitative fluctuations of VOCs in different zones within the city of Reggio Emilia (Italy), characterized by varying percentages of vegetation cover and proximity to high-traffic roads. The collected data suggest that air quality may be influenced by the spatial distribution and type of urban area, with urban parks and green zones showing lower concentrations of total VOCs compared to areas with less vegetation cover. These observations can contribute to formulating strategies to improve air quality in urban areas and emphasize the importance of vegetation in an urban context.

ObjectivesEvery organization operating in the 20s of the 21st century struggles with operating in a turbulent environment. The effects of the Covid-19 pandemic, which are still being felt today, cause some changes in customer behavior. This article focuses on the study of this phenomenon in relation to the risk perceived by customers in making online purchases. The article's purpose is to identify the broad management implications of online shopping risk perceptions among consumers during the Covid-19 pandemic.Material and methodsThe research conducted concerns customers' purchasing risk perceptions. An analysis is made of the countermeasures respondents use to minimize purchasing risks. The research used a diagnostic survey on a sample of 1,000 consumers.ResultsThe results of the conducted surveys indicate that consumers in general are aware of the risks associated with purchasing various goods via the Internet. In addition, it can be concluded that age is not significant when it comes to the perception of purchasing risks when shopping online, while concerns about buying online are dependent on the respondents' sex. There is also a statistically significant difference between the respondents' sex and sensitivity to purchase risk in various aspects.ConclusionsThis paper fulfils a gap in knowledge about shopping risk perceptions among consumers during the Covid-19 pandemic.

Cel pracyNiniejszy artykuł dotyczy reakcji konsumentów na działania z zakresu gospodarki cyrkularnej podejmowane na rynku odzieżowym. Celem autorów było zaproponowanie segmentacji klientów według kryterium ich podejścia do podejmowania decyzji zakupowych uwarunkowanego zasadami ekokonsumpcji.Materiał i metodyBadania przeprowadzono metodą sondażu diagnostycznego, przy wykorzystaniu kwestionariusza ankiety, w którym zapytano o wybrane postawy, zachowania związane z produktami oraz ochroną środowiska naturalnego oraz ocenę działań podejmowanych w tym zakresie przez przedsiębiorstwa. Próba badawcza wyniosła 1000 konsumentów.WynikiBadania pozwoliły autorom na przeprowadzenie klasyfikacji konsumentów w grupy o spójnej i charakterystycznej reakcji na działania ekonomii cyrkularnej podejmowane przez firmy. Wykazano, że istnieją istotne statystycznie różnice pomiędzy płciami w podejściu do ekokonsumcji. Nie ma znaczących różnic z punktu widzenia przedziału wiekowego, co być może wskazuje na to, że czynnikiem decydującym jest tutaj nie wiek, ale postawy proekologiczne, które nie muszą być z wiekiem powiązane – zależą od innych czynników.WnioskiWyniki badań pozwalają na znalezienie istotnych implikacji teoretycznych oraz praktycznych, a także na zaproponowanie dalszych kierunków eksploracji naukowej. Jako że gospodarka cyrkularna łączy w sobie zagadnienia zarówno z zakresu ekologii, jak i etyki, zarządzania oraz marketingu, dalsze badania powinny mieć charakter multidyscyplinarny.

Published: December 2023

ObjectivesPublic financial management is of the most global and complex nature. At this level, decisions are made that determine everything related to the collection and spending of public funds. However, we must be aware that at this level there are the greatest political entanglements, which are subject to transformation and are inextricably accompanied by changes in government teams and cooperating party coalitions. This causes general recommendations to be formulated on how to manage public funds. Discussions are held in the government or parliament forum focused on finding ways to reduce expenses. Another direction of political debates leads to a turn towards public revenues. This is expressed, for example, by striving to reduce the tax burden. The attention is therefore focused on two sides of the financial economy, i.e. on the processes of collecting and spending public funds.Material and methodsInduction was used as the main research method. It involves drawing general conclusions or establishing regularities based on the analysis of empirically identified phenomena and processes.ResultsMaintaining the stability of public finances may turn out to be one of the greatest challenges of Polish economic policy in the next few years.ConclusionsThe rate of fiscalism in Poland is lower than the average in the EU. Public revenues in Poland are characterized by a high share of social security contributions. The ratio of tax and contribution income to the potential tax base in Poland is relatively low in the case of consumption and comparable to other EU countries in the case of work. Between 2004 and 2014, the share of spending on social transfers in GDP in Poland decreased by 1.8 points. percent. which was the largest decline among all EU countries.
4-K-resolution minimalist optical system design based on deep learning
Authors: Meng Dexiao , Zhou Yan , Bai Jian 
Published: December 2023

In order to simplify optical systems,
we propose a high-resolution
minimalist optical design method based on deep learning. Unlike most
imaging system design work, we combine optical design more closely
with image processing algorithms. For optical design, we separately
study the impact of different aberrations on computational imaging and
then innovatively propose an aberration metric and a spatially
micro-variant design method that better meet the needs of image
recognition. For image processing, we construct a dataset based on the
point spread function (PSF) imaging simulation method. In addition, we
use a non-blind deblurring computational imaging method to repair
spatially variant aberrations. Finally, we achieve clear imaging at
4 K (5184×3888) using only two spherical lenses and
achieve image quality similar to that of complex lenses on the
market.

Izkušnje in doživljanje mater v zvezi z dojenjem in podpora diplomirane medicinske sestre v patronažnem varstvu
Authors: Berlec Valentina , Ramšak Pajk Jožica 
Published: December 2023

Uvod: Prva izkušnja z dojenjem je za mater soočanje s svojim telesom, občutki in učenje ob lastni izkušnji. V tem procesu mati potrebuje podporo in zdravstvenovzgojne nasvete zdravstvenih delavcev. Namen raziskave je bil raziskati doživljanja in izkušnje mater pri vzpostavljanju in vzdrževanju dojenja ter kako so ob tem doživljale podporo diplomirane medicinske sestre v patronažnem varstvu.Metode: Uporabljena je bila kvalitativna opisna raziskava. Na namenskem vzorcu osmih mater, ki so dojile in katerih otroci so bili stari vsaj štiri mesece, vendar ne več kot dve leti, z različnimi poteki dojenja, so bili opravljeni intervjuji z delno strukturiranim vprašalnikom. Intervjuvanke so bile v povprečju stare 30 let. Pridobljeni podatki so bili analizirani z vsebinsko analizo.Rezultati: Identificirane so bile tri kategorije: (1) doživljanje in izkušnje mater; (2) podpora pri dojenju in (3) vključevanje diplomiranih medicinskih sester v patronažnem varstvu. Ugotovljeno je bilo, da so predstave, ki jih imajo matere o dojenju, pogosto idealizirane, in da za vzpostavitev ter vzdrževanje dojenja potrebujejo strokovno podprte informacije in podporo.Diskusija in zaključek: Matere dojenje doživljajo zelo raznoliko in individualno, predvsem pa zelo čustveno in psihično stresno, ko ne poteka, kot bi si želele. Strokovna pomoč diplomirane medicinske sestre v patronažnem varstvu pri podpori dojenja se jim zdi zelo pomembna. Ključno je, da si ta vzame dovolj časa, da mater vodi in jo uči, kako postati samostojna pri dojenju.
