Methodology for Evaluating the Performance of a New Pulse Oximeter Model and Pulse Oximetry Algorithm in Neonates in a Clinical Trial (Exploratory Study)
Authors: Adylov T. S. , Shestak E. V. , Starkov V. Yu.
Published: September 2024

While evaluating a new domestically produced pulse oximeter model in clinical practice, we discovered a lack of references in Russian-language publications on clinical trial methodologies to assess device reliability and performance.

The aim of the study is to create a methodology for conducting a multicenter, prospective, cohort, nonrandomized, controlled clinical trial evaluating a domestic pulse oximeter.

Methods. Measurements were performed on 20 preterm infants in the neonatal intensive care unit with a mean birth weight of 2340 [1250; 3125] g and a gestational age of 35 [30; 37] weeks using a new model pulse oximeter simultaneously with the reference monitor. Multiple oxygen saturation measurements of varying duration were taken alternately from the upper and lower limbs, and the number of false desaturation alarms was recorded. Pulse oximeter saturation data were evaluated for correlation with clinical ﬁndings.

Results. Attachment of sensors to the infant's feet was found to be optimal in terms of ease of use, minimal artifact generation, and minimal interference with routine medical procedures and neonatal care. To reduce motion-induced artifacts and false alarms, the optimal period of SpO₂ monitoring to detect desaturations and bradycardia was determined to be 120 min. Due to the high variability of pulse rate (PR) and saturation in neonates, two-second intervals were determined to be optimal for comparing records from the two monitors. Matching of ECG HR and pulse oximeter PR was required to eliminate artifacts. A mathematical software model required for accelerated analysis of data collected from all sensors during the study was approved.

Conclusion. The data analysis supported the proposed methodology for conducting a clinical trial to evaluate the performance and reliability of new pulse oximetry devices.
F. M. Dostoevsky in Iran: “Triple” Translation
Authors: Rasouli Zahra , Eidlak Khalida Siyami
Published: September 2024

The creative heritage of F. M. Dostoevsky has always aroused interest among Iranian researchers and lovers of Russian literature. The article is devoted to the study of Dostoevsky’s influence on the formation and development of Persian literature. This influence found expression in such a peculiar phenomenon as a triple translation: the translation of Dostoevsky’s novel into Persian, the translation of literary text into cinematic language, and the translation of Christian content into the language of Islamic culture. The article contains an analysis of the film adaptation of “White Nights,” which was released in 2002. The author of the script for the film is Saeed Aghighi, the author of the production is an outstanding Iranian film director Farzad Motamen. The feature film is a free adaptation of Dostoevsky’s novel “White Nights” to modern Persian spatial, temporal, cultural and religious features. It can be considered the only successful Iranian film adaptation of the works of Russian classics. The film was the result of a creative dialogue of the translator, screenwriter and director with the author, interaction and mutual enrichment of different types of arts, national cultures and confessions, literary, philosophical and religious codes of communication.
FUNCTIONS OF ETIQUETTE IN THE POETICS OF F. M. DOSTOEVSKY’S NOVEL “DEMONS”
Authors: Stepchenkova Valentina
Published: September 2024

The article clarifies the value function of etiquette in the novel “Demons,” identifies communicative situations in which observance of etiquette or, conversely, departure from generally accepted norms of behavior affects the characters and beliefs of the characters. Noble, folk and folk-poetic (epic, fairy-tale) etiquette are considered. Various forms of his expression are analyzed — through the character’s speech, gestures, facial expressions, actions. The importance of moral attitudes that determine the ethics and the inner world of a person is demonstrated, reflecting to a greater extent in the external way of acting and relationships than the knowledge of the secular manners and communication culture. Despite the decent manners noted by the chronicler, Pyotr Verkhovensky regularly wanted to offend and insult his interlocutors; Stepan Trofimovich’s external untidiness appears along with his bad habits and inclinations; Verkhovensky’s “five” created a special behavioral narrative demonstrating their views and immoral appearance; the degraded and slovenly Lebyadkin begins to jauntily observe the etiquette when he sees a personal benefit in it. The different styles of the characters’ etiquette behavior allowed to identify a peculiar typology of heroes, in which, on the one side are the characters with elegant manners, but without a moral core, occupy diametric positions, on the other hand — heroes who are far removed from refined education, but not devoid of moral principles and virtues. Dostoevsky shows various functions of etiquette, many of which turned out to be a manifestation of the lack of the characters’ spirituality and served as a means to achieve their selfish goals. In addition to secular etiquette, elements of national consciousness are introduced into the poetics of the work. At its core are the Orthodox faith and love for Christ, which was a genuine ethical guideline for Dostoevsky. The convergence of the noble world with the folk world formed new value concepts of the novel’s characters, which was implemented in external behavior. The inclusion of folk culture in the cultural context introduced into the work complementary religious and ethical meanings inseparable from goodness and truth, which were significant for Dostoevsky.
Validation of EncephalApp Stroop Test for Diagnosing Minimal Hepatic Encephalopathy in the Romanian Population
Authors: Lupescu Ioan Cristian , Iacob Speranța Maria , Pietrăreanu Corina , Gheorghe Liana
Published: September 2024

Background and Aims: Minimal hepatic encephalopathy (MHE) represents the mildest form of hepatic encephalopathy. MHE has been associated with impairment of quality of life and job performance, and is a major cause of premature retiring in cirrhotic patients. However, MHE is usually overlooked by most physicians, due to its asymptomatic nature. We aim to present our experience with the EncephalApp Stroop Test for diagnosing MHE in cirrhotic patients. We also want to establish if Stroop test performance correlates with age, educational level, liver disease severity (as assessed by the MELD and Child-Pugh scores), duration of disease, previous episodes of overt hepatic encephalopathy, and other relevant clinical or laboratory parameters.
Methods: A cross-sectional observational single-center study, in which 100 adult patients diagnosed with liver cirrhosis were evaluated for the presence of MHE by using the EncephalApp Stroop Test. In parallel, 45 healthy adult controls without liver cirrhosis were recruited and tested under the same conditions as the patients.
Results: There were no age-related differences between the two groups (p=0.6). Stroop test performance of the controls (143.1 ± 20.8 seconds) was significantly better than that of the patients (171.9 ± 33.3 seconds) (p<0.0001). Stroop test results correlated with the MELD (R=0.28, p=0.005) and Child-Pugh scores (R=0.2, p=0.04). There was a positive correlation between Stroop test results and age in patients (R=0.45, p<0.0001) and controls (R=0.75, p<0.0001). Stroop test performance was not influenced by the duration of liver disease (p=0.4) or prior episodes of overt hepatic encephalopathy (p=0.25). Gender and level of education did not have an impact on Stroop test results. Alcoholic liver disease, diabetes mellitus, hyperglycemia, anemia and hyponatremia were associated with poorer performances.
Conclusions: EncephalApp Stroop Test proved to be a quick and simple method for diagnosing minimal hepatic encephalopathy in the hospital setting. Test performance was influenced primarily by age, but also by liver disease severity, anemia, hyponatremia and hyperglycemia.

Published: September 2024

Background and Aims: The world healthcare systems are currently challenged by the accumulating burden of colorectal cancer (CRC), and cancer registries represent an important segment for prevention and developing management plans, being useful in providing data regarding incidence, mortality, survival, exposure to carcinogens, lifestyle. Retrospective data from CRC patients in Romania was used to assess survival impact, costs, and cost-effectiveness considering three crucial aspects: pharmacology, chemo-/radio-therapy, and hospitalization for care and management of these patients.
Methods: 423 CRC patients from the Institutional Cancer Registry of the Prof. Dr. Ion Chiricuta Institute of Oncology in Cluj-Napoca, Romania were included in the cost analysis. For the assessment of cost efficiency of the primary treatment strategy, we collected data regarding direct medical costs associated with surgery, radiotherapy and medication, as well as the afferent day or continuous hospitalization, for each patient. For the cost-effectiveness analysis we used the method of estimation of incremental cost-effectiveness ratio.
Results: No compelling differences regarding survival time were observed in different therapeutic options per CRC stage. Substantial differences in cost effectiveness among therapeutic options in the same stage of several thousand Euros in stages I-III, while for stage IV, the ICER was more than 100,000 Euros per life saved.
Conclusions: Systematic evaluation of costs, cost-effectiveness, and survival impact, helps healthcare systems can make informed decisions to improve the management of colorectal cancer patients, optimizing outcomes while minimizing financial burden.

Published: September 2024

Background: A study was conducted in New Delhi during peak winter to investigate the impact of open versus closed windows on indoor levels of PM2.5 and PM10, given the high ambient air pollution levels during this time. Purpose: The aim was to determine whether opening windows affected indoor concentrations of PM2.5 and PM10, despite the prevailing belief that outdoor air quality significantly influences indoor air quality. Method: A PM2.5 and PM10 air quality meter was used near a window at a single location for 10 days, with measurements taken nine times daily during working hours. The experiment involved alternating between open and closed window conditions to observe any significant changes. Result: Contrary to expectations, opening or closing windows did not substantially alter indoor PM2.5 and PM10 levels. The study indicated that outdoor air might not significantly contribute to indoor particulate matter, suggesting minimal diffusion through open windows. Conclusion: The findings suggest that isolation measures alone may not effectively reduce indoor PM2.5 and PM10 levels, as outdoor sources do not significantly influence indoor air quality even when windows are opened.

Published: September 2024

BACKGROUND AND OBJECTIVE

Few studies have explored the relationship between social drivers of health and pediatric low-value care (LVC). We assessed the relationship between Childhood Opportunity Index (COI) 2.0 and LVC in children’s hospitals.

METHODS

We applied the Pediatric Health Information System LVC Calculator to emergency and inpatient encounters from July 2021 through June 2022. Proportions with LVC in highest (greatest opportunity) and lowest COI quintiles were compared. Generalized estimating equation logistic regression models were used to analyze LVC trends across COI quintiles.

RESULTS

842 463 encounters were eligible for 20 LVC measures. Across all measures, odds of LVC increased across increasing COI quintiles (adjusted odds ratio [OR] 1.06, 95% confidence interval [CI] 1.03–1.08). For 12 measures, LVC was proportionally more common in highest versus lowest COI quintile, whereas the reverse was true for 4. Regression modeling revealed increasing LVC as COI increased across all quintiles for 10 measures; gastric acid suppression for infants had the strongest association (OR 1.22, 95% CI 1.17–1.27). Three measures revealed decreasing LVC across increasing COI quintiles; Group A streptococcal testing among children <3 years revealed the lowest OR (0.85, 95% CI 0.73–0.99). The absolute volume of LVC delivered was greatest among low COI quintiles for most measures.

CONCLUSIONS

Likelihood of LVC increased across COI quintiles for 10 of 20 measures, whereas 3 measures revealed reverse trends. High volumes of LVC across quintiles support a need for broad de-implementation efforts; measures with greater impact on children with lower opportunity warrant prioritized efforts.

Artykuł ukazuje wizerunek „obcego”/„innego” z perspektywy staropolskiego piśmiennictwa w różnych gatunkach tekstów. Wykorzystano zarówno klasyczne źródła historyczne (m.in. kronikę, pamiętnik, diariusz), jak i utwory literackie (np. fraszka, pieśń).Ich autorzy stykali się z przedstawicielami różnych wyznań, narodowości, kręgów kulturowych wewnątrz państwa polskiego w wyniku kontaktów przygranicznych z przedstawicielami innymi krajów, wojen lub podczas dalszych podróży podejmowanych w różnych celach. Artykuł ma na celu stworzenie pewnego rodzaju systematyki kategorii „obcego”/„innego”. Podejmuje próbę określenia kryteriów przynależności do tej kategorii, takich jak choćby cechy charakterystyczne, religia, korzenie etniczne, pochodzenie stanowe, wygląd zewnętrzny, model zachowania, obyczaje. „Obcy”/„inny” – protestant, prawosławny, Żyd, Tatar, Turek, Francuz, Włoch, Niemiec, Szwed, Hindus itd. ‒ mógł należeć do ludności Rzeczypospolitej, być jego bezpośrednim sąsiadem, przedstawicielem państw, narodów i stanów zamieszkujących Europę oraz Orient, a nawet Indie.W jego postrzeganiu bardzo dużą rolę odgrywała osoba autora. Ważne są także stereotypy i mity funkcjonujące w określonej grupie społecznej, jak również stopień emocjiz tym związanych. Postrzeganie „obcego”/„innego” stanowi ważny element staropolskiego światopoglądu oraz ówczesnej świadomości społecznej.
Wpływ wielkiego kryzysu gospodarczego lat trzydziestych XX wieku na dochody z pracy w rolnictwie i przemyśle (na przykładzie województwa kieleckiego)
Authors: Słabińska Elżbieta
Published: September 2024

Objawem wielkiego kryzysu był spadek płac nominalnych i realnych pracowników najemnych w niemal wszystkich sektorach gospodarki. W przypadku robotników rolnych nastąpił on od 1928/1929 r., a pracowników umysłowych od 1931 r. W przemyśle redukcje płac robotników rozpoczęto w 1929 r., a pracowników umysłowych w 1931 r.Spadek wynagrodzeń w rolnictwie i przemyśle był stopniowy i w niejednakowym stopniu dotknął różne kategorie pracowników. Obniżki dotyczyły głównie pieniężnej części zarobków. W wyniku zmniejszenia płac nominalnych nastąpiło „spłaszczenie wynagrodzeń”. W rolnictwie przybrało znaczne rozmiary.Częstym zjawiskiem podczas wielkiego kryzysu było niewypłacanie pracownikom wynagrodzeń, wbrew warunkom układów zbiorowych, oraz nieregularne płace. „Kosztownych” robotników zastąpiono „tanimi”. Pracodawcy przeprowadzali zwolnienia grupowe i indywidualne. W konsekwencji utraty zatrudnienia pracownicy tracili nie tylko pieniężną część zarobków, ale też niepieniężną, z której najdotkliwszą stratą było mieszkanie służbowe.
Źródła sztuki. O Sonacie Belzebuba Stanisława Ignacego Witkiewicza
Authors: Nowak Witold
Published: September 2024

W artykule dokonuję prezentacji i analizy poglądów na źródła sztuki, jakie Stanisław Ignacy Witkiewicz (1885‒1939) zawarł w jednym ze swych ostatnich dramatów ‒ Sonacie Belzebuba. Przedstawione tam filozoficzno-estetyczne poglądy Witkacego odnoszę do szerszego kontekstu jego poglądów na kulturę, a także do przemian myśli estetycznej i społecznego imaginarium XIX i XX w., co pozwala ukazać zarówno ich oryginalność, jak i punkty zbieżne z powszechniejszymi tendencjami myślowymi. Staram się pokazać, że utwór Witkiewicza opiera się upływowi czasu dzięki postawieniu problemów „metafizycznych” ‒ wykraczających poza zainteresowania konkretnej epoki ‒ jak też dzięki elementom komizmu i ironii czyniących zeń dzieło otwarte na wielość interpretacji.

Uprooted by a petrochemical company: The ethical dimension of open strategy
Authors: Zanoni Beatriz Lima , Capucho Pablo Henrique Paschoal , Martins Ingrid De Matos , Rese Natália
Published: September 2024

Abstract Purpose: This article debates the open strategy process, understanding the social pressure on companies as a highlighted dimension within the context of formulating strategy. Originality/value: Within corporate environmental and social crimes and negligence, companies can maintain their closed strategies and try to avoid institutional and social protests by responding ceremonially. To analyze this relationship, we use the theoretical framework of open strategy, assuming a practical perspective of this worldwide social phenomenon, and we also propose a discussion agenda for the ethical dimension of formulating strategy. Design/methodology/approach: We have conducted a documental case study of the Braskem “geological phenomenon” which occurred in Maceió, Alagoas, in 2018 using newspaper reports from Folha de S.Paulo and Estadão, as well as business reports. Based on these documents, we debate the corporate environmental crime that occurred (ecocide), which caused great losses on the part of the local residents. The documents were analyzed using content analysis and interpreted in light of the delineated theoretical framework. Findings: We emphasize the importance of including the ethical dimension in debates about open strategy and propose a reflection about taking this opening seriously. Openness is built from a dialogic perspective, and social practices are considered a social-historic and culturally situated framework.
Characterization of self-compacting concrete incorporating fly ash and rice husk ash at fresh and hardened state

Published: September 2024

Abstract This work studies the feasibility of using rice husk ash (RHA) as a partial replacement for Brazilian Portland cement in producing self-compacting concrete for structural purposes. The RHA used is produced under controlled burning conditions in a fluidized bed. The concrete mix design is presented in detail to show how to find the best combination of the regional material to produce self-compacting concretes with good fresh and hardened characteristics. Concretes produced in the proportions of 5%, 10%, 15%, 20%, and 25% of replacement of cement by RHA have been studied, with the addition of 15% of fly ash and w/b of 0.45. In the fresh state, flowability, viscosity, and passing ability tests have been conducted. Additionally, mechanical tests were performed to assess the axial compressive strength and splitting tensile strength in the hardened state. The fresh state properties are influenced by the RHA content, reducing its flowability and passing ability with the increase of this material. The hardened state properties of the mixtures with RHA have shown increased resistance when compared to plain concrete. The mixture with 15% replacement had the best results. Concretes of 20% and 25% had their strength increased to a lesser degree. However, they remain a good option when increasing the superplasticizer quantity to improve the fluid state's properties.
The Riemann's Hypothesis, the Prime Numbers Theorem (PNT), and the Error
Authors: Ing Mg Carlos A Correa
Published: September 2024

In this simple paper, a small refinement to the Prime Number Theorem (PNT) is proposed, which allows us to limit the error with which said theorem predicts the value of the Prime-counting function π(x); and, in this way, endorse the veracity of the Riemann Hypothesis. Many people know that the Riemann Hypothesis is a difficult mathematical problem - even to understand - without a certain background in mathematics. Many techniques have been used, for more than 150 years, to try to solve it. Among them is the one that establishes that, if the Riemann hypothesis is true, then the error term that appears in the prime number theorem can be bounded in the best possible way. Specifically, Helge von Koch demonstrated in 1901 that it should be:

Authors:   Research Scholar, Kavayitri Bahinabai Chaudhari North Maharashtra University, Jalgaon, Maharashtra, India, Patil Nandkishor Chhagan , Patil Nitin Jagannath
Published: September 2024

Objectives: Lung cancer is one of the most prevalent causes of carcinoma-related fatalities globally; precise and effective diagnostic instruments are desperately needed. Researchers and physicians continue to encounter difficulties when aiming to employ deep learning models in healthcare environments for recognizing lung cancer and to achieve higher sensitivity and accuracy on large data sets, despite several advancements in this field. Our study builds upon an extensive review of existing lung cancer detection methods, highlighting their strengths and weaknesses. The performance of this model deteriorates when there are variances in Lung CT image features such as rotation, tiling, and other aberrant image orientations. This study aims to address the issues associated with variations in lung CT images. Methods: A hybrid deep learning model that blends the potency of CNNs with the cutting-edge design of capsule networks is proposed. Inspired by recent advancements, our model integrates the VGG19 and Capsule Network architectures to address orientation-related challenges often encountered in traditional CNN-based approaches. The creation, training, and assessment of this hybrid model for lung nodule identification and categorization are our main research goals. Findings: We anticipate that our research has yielded several valuable outcomes, including improved nodule classification accuracy of 99.20%, reduced false positive rates, and minimized training times. Novelty: This research employing a hybrid deep learning model that combines the capabilities of the VGG-19 and capsule network could lead to more widespread utilization in cancer diagnosis by enhancing early lung cancer detection and developing the field of medical image analysis. The shortcomings of convolutional neural networks are addressed with Capsule Network. Leveraging the knowledge and insights gained from lung cancer detection, our research also investigates the potential applicability of our methodology to identify other types of medical image classification such as breast and ovarian cancer.

The Effect of Multicollinearity on Feature Selection
Authors:   Professor, Statistics, Bharathiar University, India, Muthukrishnan R , James C K
Published: September 2024

Objectives: To provide a new LASSO-based feature selection technique that aids in selecting important variables for predicting the response variables in case of multicollinearity. Methods: LASSO is a type of regression method employed to select important covariates for predicting a dependent variable. The traditional LASSO method uses the conventional Ordinary Least Square (OLS) method for this purpose. The Use of the OLS based LASSO approach gives unreliable results if the data deviates from normality. Thus, this study recommends using, a Redescending M-estimator-based LASSO approach. The efficacy of this new method is checked against the ordinary LASSO method using a real dataset and also a simulation study with various levels of sample size (N=100,200,1000), different numbers of predictors (p=10,15,20), and varying degrees of correlation (ρ = 0.96, 0.98, 0.999). Findings: The usual OLS-based LASSO finds it difficult to select important variables when the independent variables are correlated. The Redescending M-estimator-based LASSO addresses at tackling the pitfalls faced by Conventional LASSO methodology. Among other things, the proposed method is far better than the old-fashioned LASSO since it helps to pick out significant factors more effectively, particularly in the presence of multicollinearity. Novelty: The conventional OLS-based LASSO approach selects a greater number of non-significant variables in the presence of multicollinearity. The proposed Redescending M-estimator-based LASSO approach selects the important variables in the presence of multicollinearity. Keywords: Feature Selection, LASSO, MDAE, VIF, Variable Selection

Limestone is a sedimentary rock mainly composed of calcium carbonate mineral. Limestone is quarried abundantly in and around Piduguralla region, Andhra Pradesh, India. Good quality limestone is used to manufacture cement. Calcium oxide is used as white wash which is obtained by heating calcium carbonate. Limestone, as fine powder or as coarse grains is also used as base for paint. In this research, the calcium carbonate mineral in the form of limestone procured from Piduguralla region is used in concrete in two different forms i.e as powder form and as sand form. The cement was partially replaced with the calcium carbonate powder when the calcium carbonate is used as fine powder. The natural river sand was partially/fully replaced with calcium carbonate sand when the calcium carbonate is used as sand (coarser) form. Experiments on cube, cylinder and beam specimens are conducted using Universal Testing Machine to establish compression strength, split tensile strength and flexural strength of concrete having calcium carbonate. The test results support the usage of calcium carbonate in concrete to enhance the strength of concrete. Up to thirty percent cement can be replaced with calcium carbonate powder without adversely affecting the strength of concrete. Natural river sand can be partially/fully replaced with calcium carbonate sand which in turn increases the strength of concrete, but the optimum percentage of replacement is fifty percent of natural sand

The study investigated the grain size criteria, mechanical characteristics, and corrosion behavior of Cu-14Al-4.5Ni-0.7Mn shape memory alloy (SMA) with the micro-addition of 0.06 wt% Lanthanum (La). Using standard melting and casting procedures, the alloy compositions were melted at 1300 ℃ in an arc furnace with an argon atmosphere. The cast compositions without thermal treatment were machined and tested for physical properties including density and percentage porosity, corrosion behavior, and mechanical properties like hardness, ultimate tensile strength, yield strength, fracture strain, percentage elongation, specific strength, and fracture toughness. The average grain size, profile plot, and grain size distribution were all determined using ImageJ software. The microstructural observations revealed the presence of α-phase, β-phase, and intermetallic phases, including the coarse α+γ2 phase, which contributed to the improved characteristics. The inclusion of lanthanum resulted in a drop in the average grain size of the parent alloy from 9.25 μm to 6.08 μm, indicating a clear correlation between property improvement and microstructure refinement. The composition's tensile strength and yield strength increased with the La micro-addition by 22.14% and 20.31% respectively while the hardness value increased by 17.3%. The fracture strain of the modified composition increased by 20% compared to the unmodified composition while the percentage elongation increased by 7.7% and a 22.5% increase in fracture toughness was achieved. The modified CuAlNiMn SMA also showed a significant improvement in corrosion resistance to NaCl solutions which was so evident at 144 hours of the study for 0.5 M of NaCl solution and at 96 hours for 1.0 M of NaCl solution. The results showed that CuAlNiMn SMA with micro-addition of La had better physical, corrosion, and mechanical characteristics than unmodified CuAlNiMn alloys

A Sociedade Brasileira de Vácuo (SBV) prima por conectar tecnologia e ciência, e esse número afortunadamente não é diferente.
Assim, vários avanços tecnológicos, de diferentes áreas de pesquisa, são apresentados: óptica, eletrônica e mesmo qualidade. Esses trabalhos indicam soluções surpreendentes para uma série de questões.
Usando óptica, não eletrônica, Gonçalves et al. propõem superar limitações existentes nos atuais radares e também criar proteções, como, por exemplo, uma “isca”. Kiohara et al. apresentam o uso de fibra óptica nas conexões radar-aeronave, enquanto Carreira et al. se preocupam com a digitalização de tal comunicação.
Algoritmos são fundamentais em qualquer área da ciência. Portanto, enquanto Silvestre et al. utilizam Monte Carlo para indicar a posição de um objeto, Silva et al. fornecem uma proposta de encriptação em um processador.
Quanto a voar com menor estresse ou ser capaz de usar dispositivos com segurança mesmo se houver componentes com prazo de validade desatualizado? Essas são as soluções mostradas por Brandão et al., que criaram um método não destrutivo para validar componentes eletrônicos que não foram usados no prazo especificado, e por Souza et al., que estudaram o comportamento de passageiros em um aeroporto de grande porte.
Esse conjunto de estudos, amplo, de imediata aplicação e abordagem transversal, mostra como a criatividade une ciência e tecnologia para gerar novos caminhos e produtos.

B a c k g r o u n d . It was emphasized that due to the fact that in 2024 the planned change of power in Ukraine due to martial law will not take place, trust in the government will be the main source of ensuring its legitimacy. The study of the dynamics and structure of political trust, as well as the characteristics of people who are supporters of various scenarios of increasing the level of trust in the authorities, is an issue that is relevant not only of the theoretical side, but also from the position of ensuring a timely response to public requests to ensure the stability and support of the internal potential for the country's fight against the enemy. M e t h o d s . The methods of online survey of respondents using questionnaires and a panel of psychological methods were used to study the level of political participation, values, cognitive orientation (locus of control), and the level of paternalism in relation to government institutions. Content analysis was used to analyse the political discourse in social networks regarding the conditions for increasing trust in the authorities in wartime conditions. The scales selected on its basis were offered for evaluation by our subjects. R e s u l t s . Three groups of respondents with different levels of trust in the authorities were distinguished: complete distrust, partial distrust and unconditional trust. The political and psychological features of people with different levels of trust in the authorities were analysed, in particular differences in the level of political participation, orientation of the locus of control, political preferences of groups with partial and unconditional support of the authorities were revealed. The conditions put forward in the discourse on social networks as significant for maintaining / increasing trust in the current government were analyzed, as well as the analysis of differences in the importance of certain conditions in our subjects with different characteristics. C o n c l u s i o n s . A decrease in the level of trust in the authorities in the conditions of the prolongation of the war is demonstrated, a significant list of complaints against the actions of the current government is highlighted (increasing tendency to authoritarianism, lack of transparency in communication, insufficient actions to fight corruption, transfer of the economy to military rails, etc.) and a corresponding list of conditions that put forward various groups in order to return / increase trust in the authorities.

B a c k g r o u n d . The relevance of the study of the problems of psychological well-being of the individual is due to extreme circumstances in the development of human society, which are, for example, the COVID pandemic, local wars, as well as sufficiently high requirements for the professional achievements of the individual in society, which affect the current trends of changes in social interaction. The purpose of the study is to study personal predictors of achieving professional success as a component of psychological well-being. M e t h o d s . The research used theoretical methods (analysis, comparison, generalization, systematization, empirical, namely: 1) The scales of psychological well-being by K. Riff. 2) Optimism and Activity Scale (AOS) by N. Vodopyanova, M. Shtern; 3) SAMOAL questionnaire (A. V. Lazukin, adaptation by N. F. Kalinaya), as well as statistical: correlation analysis according to K. Pearson (r), statistical criterion of significance of difference (Mann – Whitney U-criterion). R e s u l t s . It was found that professionally successful subjects are highly active in combination with adaptability to new situations, internal locus of control and high sociability. A positive worldview is an important attribute of psychological health and well-being, characteristic of professionally successful people. Optimism as a positive life attitude combined with activity (energy) is a psychological resource of individual resistance to professional and life stresses. Reliably significant differences between the groups of professionally successful subjects and the control sample were determined on the scale "orientation in time" and "spontaneity". C o n c l u s i o n s . It is substantiated that the professionally successful researched feelings of subjective well-being are associated with reliable social ties, good health and satisfaction with the activities they perform. It is proved that for the subjects of the control sample, the subjective feeling of well-being is primarily associated with the absence of tension in life, and self-actualization is an important aspect of life creation for professionally successful people. It is argued that professionally successful subjects are satisfied with everyday activities, understand the importance of living here and now, are open to new ideas, opportunities and impressions.
