Today's cultural and artistic arena is a very heterogeneous phenomenon – the dominant artistic processes have shifted dramatically. Martial law, military actions of the state prompted the creative community to change the system of values – to readjust to a different plot, a figurative series. Agitation art dominates – daily reality dictates the need for creative personalities to find ways to psychologically support those who defend the borders of the state from the end of February 2022. The task of the research is the possibility of positioning art to accelerate the victory of Ukraine in the war with the Russian invaders, considering art as a method of raising the patriotic mood of the population, on agitation, moral support of Ukrainian soldiers, which is analyzed on the example of the works of the Kyiv painter Oleksandr Lyhosherst. Emphasis is placed on changes in the dominant forces in the cultural and artistic field of modern Ukraine, the cause of which is military aggression. Emphasis is placed on the war as the reason for a radical change in the storyline of the work of Ukrainian artists. The leading characteristics of Oleksandr Lyhosherst's work are highlighted, a brief overview of the formation of his creative path is given. Individual examples of the artist's work are presented, the influence of those phenomena that were important for the formation of his creative language is characterized.

THE RETURN OF UKRAINIAN CULTURAL TREASURES: A LONG ROAD HOME
Authors: SVERDLYK Zoriana
Published: March 2024

An analysis of various aspects of the return of Ukrainian cultural treasures has been conducted. The article examines the collaboration between the Borys Grinchenko Kyiv University and the Archive-Museum of the Ukrainian Free Academy of Sciences in the USA in 2009. It demonstrates that archival materials and personal belongings of the Kosach family were transferred from the Funds of the Archive-Museum of the Ukrainian Free Academy of Sciences to the Lesia Ukrainka Research Institute. It is indicated that in 2010, a concept was developed and the initial stage of the “Cultural Treasures of Ukraine” information system was implemented. This system comprised eight registers of cultural treasures: those lost during and as a result of World War II (libraries, museums); those returned to Ukraine; those related to the history of the Ukrainian people located outside Ukraine; those sought nationally; those sought upon requests from other countries; confiscated cultural treasures; objects with permits for temporary export from Ukraine. It is noted that during this period, exhibitions, cultural projects, presentations, and discussions related to the return of Ukrainian cultural treasures were organized. After the cessation of the State Service for Control over the Movement of Cultural Values across the State Border in 2011, the Department for the Control of the Movement of Cultural Values was established within the Ministry of Culture of Ukraine. Importantly, despite funding constraints due to an economic crisis, efforts were made to search for cultural treasures and maintain cooperation with the Ukrainian diaspora. Additionally, the article highlights initiatives concerning the return of Scythian gold and the intricate process of repatriating cultural artifacts to Ukraine. The protracted legal battle in this matter is analyzed. Methodological work was also carried out to establish specific norms for conducting expertise on cultural values, leading to the approval of Methodological Recommendations for the State Expertise of Cultural Values by the Ministry of Culture of Ukraine in 2019. Notably, contacts with the United States of America and Germany have been of particular importance in the realm of cultural treasures repatriation.
ENCAUSTIC AS AN ANCIENT PAINTING TECHNIQUE: A FAILING TRADITION
Authors: ZAITSEVA Veronika , BUIHASHEVA Alla , PROKHOROVA Nataliya
Published: March 2024

The article highlights the peculiarities of the encaustic painting technique and the main problems of preserving this unique technique in the modern art of Ukraine. The meaning of the concept of “encaustic” is revealed. Considerable attention is paid to the technological varieties of encaustic as an ancient pictorial art. Thus, ancient authors wrote about the expressiveness and beauty of the encaustic technique, but, at the same time, “wax painting of the ancients” turned out to be one of the mysterious techniques. First of all, this is due to the fact that very few encaustic works have survived, and the description of technologies was almost absent. Thus, after studying the “Fayum portraits” found in 1887 in Middle Egypt (the Fayum oasis), it was possible to determine that the funerary masks were made in the encaustic technique. Mentions of encaustic works date back to the ancient literature of the times of imperial Rome. During the Renaissance, even Leonardo da Vinci tried to unravel the mystery of encaustic painting, but even he had very little information about this technology. According to the descriptions, it was necessary to solve a complex technological process, so the masters collected information piece by piece and experimentally implemented this technique. These were the first stages of the revival of encaustic painting, which is also called wax painting, because the basis of encaustic paints was wax. The stability of this painting technique was ensured, in particular, by the presence of various resins, linseed oil and dyes of natural origin in the composition of encaustic paints. These paints were applied layer by layer on special soils under high temperature. The exceptional artistic value of the encaustic technique made it possible to preserve it and gave the prospect of revival thanks to the creative searches of artists of the 1970-1995 years of the 20th century. Painting with wax paints meets all the requirements of modern monumental art along with frescoes and mosaics. Modern construction technologies and materials provide ample opportunities for monumental artists to solve various artistic and plastic tasks related to the application of the encaustic technique. The article also considers the role of encaustic in modern easel and monumental art. The work of modern masters of Ukraine who worked in the encaustic technique is analyzed.

Published: March 2024

Proppant flowback is a problem in Xinjiang oilfield. It decreases production rate of a fractured oil well, corrodes surface and downhole facilities and increases production costs. Curable resin-coated sand is a common technique to control proppant flowback. This article presents an experimental investigation whether it is feasible to control proppant flowback by use of resin-coated sand and whether resin-coated sand has a negative effect on proppant pack conductivity. It included two kinds of experiments, Proppant flowback experiment measured critical flow rate while the Proppant pack conductivity one measured proppant conductivity. The experimental results of proppant flowback show that the critical flow rate of resin-coated sand is far greater than that of common sand which means proppant flowback would not happen by resin-coated sand tail-in. Compared to Xinjiang sand conductivity, resin-coated sand conductivity is far smaller though it declines slightly which means use of resin-coated sand would lead to conductivity loss and sequentially results in production impairment. Experimental results show that it is feasible to control proppant flowback by use of resin-coated sand and resin-coated sand would affect fracture conductivity of a fractured oil well. Based on the experimental results, resin-coated proppant conductivity can be improved by use of resin-coated ceramic or liquid-resin-coated proppant. The achievements can give a direction towards how to select a resin-coated proppant and how to improve resin-coated proppant.

Published: March 2024

Numerical literacy, the ability to interpret and apply numerical data, is crucial for success in various fields, including computer science. Traditionally, Pascal programming courses rely on passive learning methods, hindering students' development of numeracy skills. This study investigated the effectiveness of project-based learning (PjBL) in improving numeracy literacy among 46 Physics Education students enrolled in a Pascal programming course at Mataram University in Indonesia. The PjBL approach involved real-world projects requiring students to apply and analyze numerical data within their programming tasks. Findings revealed significant improvements in numeracy literacy, with success rates of 97% for short analysis, 87% for medium analysis, and 46% for long analysis. Overall, the average learning outcome was 84 out of 100, demonstrating the potential of PjBL as an effective learning model for enhancing numeracy skills in programming contexts. Further research is encouraged to refine PjBL implementation models and optimize its impact on numeracy literacy in STEM education.
Synthesis and Characterization of K2O/ACT Catalyst for Biodiesel Production from Beef Fat Waste
Authors: Putri Vani Dwi Hani , Samik
Published: March 2024

The increasing use of petroleum as fuel has depleted fuel, so alternative fuels such as biodiesel are needed because they are environmentally friendly and come from vegetable and animal sources. Therefore, this article presents biodiesel production from beef fat using a K2O/ACT heterogeneous base catalyst derived from egg shells. The Eggshell becomes a CaO catalyst after 3 hours of calcination at 900°C. The K2O/ACT catalyst was synthesized by impregnating CaO with KOH and characterized using XRD and BET. The K2O/ACT catalyst was compared to the CaO catalyst for transesterification activity under appropriate conditions (reaction temperature 65°C, catalyst loading 3% by weight, oil to methanol molar ratio 1:12, and reaction time 3 hours). The catalytic activity of the catalyst was determined to be 98.40% Fatty Acid Methyl Ester (FAME). The insertion of K2O into the CaO catalyst increases the basicity characteristics, thereby increasing the catalytic activity of transesterification.

O vírus da imunodeficiência humana (VIH) constitui uma das infeções sexualmente transmissíveis com maior impacto na vida do doente, sendo fundamental o diagnóstico precoce de forma a iniciar terapêutica antirretroviral atempadamente e evitar a evolução da doença.Apresentamos o caso de uma mulher de 60 anos com quadro de epigastralgia, ageusia e perda ponderal de 9% com 3 meses de evolução. Foi solicitado estudo analítico, endoscopia digestiva alta e baixa e radiografia do tórax, que revelaram hérnia do hiato volumosa e linfopenia ligeira. Um mês depois desenvolveu dispneia, confusão temporoespacial e alteração da fala, tendo recorrido ao serviço de urgência onde foi diagnosticada infeção por VIH. Durante o internamento objetivou-se infeção por Pneumocystis jirovecci e diagnóstico de linfoma primário do sistema nervoso central, ambas doenças definidoras da síndrome da imunodeficiência adquirida (SIDA).Com este caso pretendemos alertar para a exclusão do diagnóstico de VIH em doentes com sintomas constitucionais e para o seu rastreio não só em populações de risco como também, pelo menos uma vez durante a vida, em adultos dos 18 aos 64 anos sem fatores de risco.

Authors: SOFUOGLU Rıza Sercan , DİBEK BÜYÜKDİNÇ Melda , BAŞAK Okay
Published: March 2024

Introduction: There is currently a lack of primary care or community-based regional and national data concerning vaccination rates among older individuals in Turkey. Thus, the present study aimed to determine the pneumococcal, influenza, and herpes zoster vaccination rates associated factors among individuals aged 65 and over in Efeler, the central district of Aydın Province, Turkey. Materials and Method: An analytical, cross-sectional study was performed between September 2022 and November 2022 at 10 family health centers randomly selected from a total of 34 such centers in Efeler. The study’s calculated sample size was 321 participants. During the study period, a researcher administered data collection forms that had been developed via a literature review to older patients on a face-to-face basis. The data were analyzed using IBM SPSS 20.0 statistical software, while descriptive statistics as well as chi-square and logistic regression tests were employed to identify the factors associated with vaccination rates among this population. The statistical significance level was set as p <0.05. Results: Among the 321 participants, 51.4% were male, 70.7% were in the 65–74 age range, 77.0% were married, and 88.2% had at least one chronic disease. Moreover, 90.0% were aware of the vaccines recommended for their age group, while 81.3% stated that vaccines had been recommended to them after the age of 60. In the past year, 39.3% of participants had received an influenza vaccine, 6.2% had received at least two doses of pneumococcal vaccine, and 0.3% had received a herpes zoster vaccine. The influenza vaccine coverage in the past year was 2.1 times higher in those aged 75 years and over than in younger participants (p = 0.005), while it was 3.9 times higher in those with chronic diseases compared to those without (p = 0.004). The participants with active employment had received at least two doses of pneumococcal vaccine, indicating a vaccine rate 13.1 times higher than among those without employment (p < 0.001), while participants with chronic obstructive pulmonary disease (COPD) and/or asthma had a vaccination rate 7.8 times higher than participants without either condition (p < 0.001). Conclusion: The overall vaccination coverage among the participants was quite low. While the influenza vaccine was commonly received, the herpes zoster vaccine was only rarely administered. An older age and the presence of chronic diseases were associated with higher influenza vaccination rates, while being in active employment and having COPD and/or asthma were associated with higher pneumococcal vaccination rates. Further qualitative studies are required to elucidate the behaviors and attitudes of the younger members of the older adult age group who do not have chronic diseases when it comes to receiving vaccines included in the program.

Between July and November 2022, 49 intensive care patients were admitted to a training and research hospital in northeast Turkey. The data were collected using the Patient Information Form, Critical-Care Pain Observation Tool, Ramsay Sedation Scale, and Nursing-Delirium Screening Scale. Results: The patients’ mean age was 76.90±8.29 years. The longer the length of stay in the intensive care unit, the incidence of delirium increased. The incidence of delirium increased in patients aged 70–95 years (p=0.007). Patients with delirium experienced insomnia and agitation and used more sedative drugs (p<0.05). The predictors of early delirium were sedation (β=0.869), agitation (β=-0.582), and diastolic blood pressure (β=0.258). The predictors of delirium were pain (β=-0.599) and sedation (β=0.267). Conclusion: The study demonstrated that older age, agitation, sedation, pain, and diastolic blood pressure predicted delirium in elderly COVID-19 inpatients. It is necessary to identify and eliminate risk factors to reduce the risk of delirium in elderly patients. Nurses should play an active role in identifying and managing delirium in elderly COVID-19 patients. Keywords: COVID-19; Delirium; Aged; Intensive Care.

Federated Learning (FL) has emerged as a promising approach to collaborative machine learning without the need to share raw data. It enables decentralized model updates while preserving the privacy of each device and reducing the communication overhead. This experiment evaluates the effectiveness of the personalized FL algorithms, namely FedAvg, APPLE, FedBABU and FedProto, in a decentralized setting, with a particular focus on the Fashion MNIST dataset, which is characterized by a non-ideal data distribution. The objective is to identify which algorithm performs optimally in image classification tasks. The experimental results show that both FedProto and APPLE have nearly equivalent and better performance compared to FedBABU and FedAvg. Interestingly, increasing the number of uploads in FedBABU leads to similar results to APPLE and FedProto. However, under limited upload conditions, FedBABU performs similarly to FedAvg. These results provide valuable insights into the differential performance of personalized FL algorithms in non-id data scenarios and provide guidance for their application in distributed environments, especially in sensitive domains such as medical, military and confidential image analysis tasks where privacy and communication efficiency are paramount concerns.

Background: Resistance and side effects of antiepileptic drugs (AEDs) pose a challenge in epilepsy therapy due to the limited drug bioavailability in penetrating the Blood-Brain Barrier (BBB). Nanoparticles can be one solution by encapsulating AEDs to enhance drug distribution to target cells. This study systematically assesses 1) the characteristics of nanoparticles, and 2) the potential of nanoparticle AEDs in managing seizures in experimental animal models. Methods: This systematic literature review is limited to studies published between 2013 and July 2023 in the PubMed, ScienceDirect, ProQuest, MEDLINE, and Scopus databases. Inclusion criteria encompass studies involving animal models of epilepsy, that exploring nanoparticle-based of AEDs. These studies compare the characteristics of nanoparticles and their antiepileptic efficacy with non-nanoparticle groups. Review articles, publications in non-English languages, and ongoing studies without published results are excluded. Result and Discussion: Fourteen studies met the inclusion criteria for this research. All studies utilized nanoparticles (n = 14). Lipid nanoparticles have a more compact size than any other nanoparticle, while the combination preparation method has an optimal nanoparticle formation in both lipid and polymeric nanoparticles. In animal model results indicated that nanoparticle-based drugs were beneficial in reducing seizure scores, improving seizure onset latency, and providing neuroprotective effects. Conclusion: The characteristics of nanoparticle drug delivery varied, influenced by formulation factors and preparation methods. Nanoparticle-based AEDs exhibit higher efficacy compared to conventional AEDs. All studies included present an opportunity for the development of epilepsy therapies, although future studies are needed to confirm these findings.

Objective: This study aims to determine the effect of carbofuran exposure during the embryonic period on the histopathological images of the liver of one day old and two-week-old chicks after they hatch. Method: 60 embryonated chicken eggs from broiler parent stock with an average weight of 62.064 mg were divided into two observation groups: one day old chicks and two-week-old chicks after they hatched. Carbofuran was dissolved in aquabidest and then was injected into the egg yolk at a dose of 0.0106 mg/0.1 ml/egg (P1) and 0.0127 mg/0.1 ml/egg (P2). The control group (P0) was injected with 0.1 ml of aquabidest. All eggs were incubated in an electric incubator until they hatched. The livers of one day and two-week-old chicks were collected for HE staining. The variables observed were the level of liver cell necrosis in the central vein and Kiernan's triangle. Data were analyzed using Kruskal Wallis and it continued with multiple comparison tests. Results: The results showed that the carbofuran group of one day old chicks treated with at a dose of 0.0106 mg/0.1 ml/egg had a significant effect on necrosis of liver cells in the central vein and in Kiernan's triangle. Moreover,the carbofuran group of two week old chicks treated at a dose of 0.0127 mg/0.1 ml/egg (P2) and 0.0106 mg/0.1 ml/egg (P1) had a significant effect compared to the P0 group (p<0.05). Conclusion Carbofuran insecticide at a dose of 0.0127 mg/0.1 ml/egg was proven to cause the necrosis of liver cells in the central vein and in Kiernan triangle of one day and two-week-old chicks when they were exposed to carbofuran during the embryonic period.

Bronchopulmonary infections (BPIs) are a real public health problem, both in terms of frequency and treatment difficulties. They represent a pathogenic germs reservoir whose occurrence progresses over time, posing a serious therapeutic problem. The aim of this study was to estimate the pulmonary infections prevalence and to study the germs isolated epidemiology at Batna’s PHE. This work is a retrospective descriptive epidemiological study carried out over an extending period from January 2018 to December 2022, covering all pulmonary origin samples received at the central laboratory of the Batna’s Public Hospitalian Establishment (PHE Batna). 2,393 total samples were analyzed. The prevalence of IBPs was 10.44%. In our study, we found a women predominance (54.40%), the percentage of IBPs in adults was 88.80% and 11.20% in children. The greatest number of people infected was in autumn, 34.40% compared with 28% in winter and 21.20% in spring, while only 17.20 were found in summer. The majority isolated strains were Gram-negative bacilli, with BNF accounting for (40%) of isolates. Pseudomonas aeruginosa ranked first (22.69%), followed by Streptococcus D (12.69%), Escherichia coli (9.32%), Pseudomonas sp. (8.84%), Haemophilus sp. (5.38%), Klebsiella pneumoniae (5%), Branhamella sp. (5%) and Streptococcus sp. (4.61%). These results may help to better understand and manage PBI in this region, focusing on the most frequent strains for the appropriate therapeutic strategies development.

Alcohol dehydrogenases (ADHs) are zinc-containing enzymes that catalyze the oxidation of alcohols to aldehydes or ketones. The enzymes also play a critical role in the metabolism of a number of drugs and metabolites containing alcohol functional groups. Kinetic parameters of yeast alcohol dehydrogenase (ADH) was estimated using spectrophotometer, optimum temperature and pH for ethanol, as well as ADH specificity to other substrates was determined. Results from the assay showed value for the initial velocity of reaction of the enzyme estimated as 0.297. Change in concentration of NADH which correspond to ADH activity for ethanol was calculated as 48nanokatals (4.8 X 10-5 mol-1l), the results also showed average values of the Km and Vmax of ADH for ethanol as estimated from Michaelis-Menten and Line weaver-Burk double reciprocal plots, to be 21.5mM and 0.426 respectively. Optimum temperature and pH of ADH for ethanol were estimated to be 25 °C and 8 respectively. Although, reaction specificity of ADH to other substrates showed gradation between propan-2-ol and ethanol with ethanol showing highest activity and methanol least. 2-propene-1-ol also presented high enzyme activity relative to ethanol. In most of enzyme assays, enzyme activity is determined by measuring the rate of conversion of substrate or rate of production of products within a given period of time. In this experiment, the rate of oxidation of NADH was monitored since NADH has a known maximum light absorbance at 340nm.

The COVID-19 pandemic, caused by the SARS-COV-2 virus, has not only led to significant morbidity and mortality worldwide but has also profoundly impacted the quality of life of people post-recovery. This study aims to analyze the quality of life among post-COVID-19 people in Kolhapur, India, and to explore associations between their quality of life with their selected socio-demographic variables. A qualitative approach was considered. A non-experimental, exploratory research design was adopted, with data collected from 225 people through convenient sampling technique. Structured interview questionnaires and the Patient Reported Outcome Measurement Information System (PROMIS) scale were utilized. The majority of subjects reported good quality of life (69.33%), with a smaller proportion reporting average quality (30.22%), and only one subject (0.44%) indicating poor quality of life. Statistical analysis revealed a significant association between quality of life and type of diet and treatment, while no significant associations were found with other demographic variables. This study underscores the importance of addressing the psychological and physical well-being of post-COVID-19 people and suggests the need for tailored rehabilitation programs to improve their quality of life.
