Published: April 2024

Backgrounds: Visceral leishmaniasis (VL) is a vector-borne disease posing increasing public health concerns. Although efforts to eliminate VL are underway, its global risk distribution remains unclear, because of changes in transmission risk.

Methods: Worldwide province-level data on VL incidence were obtained from multiple sources. We analyzed the global evolution features of VL and estimated its ecological niches with boosted regression tree models. A risk map was generated to analyze regions with high VL risk.

Results: A total of 558 articles and 2,694 records from 310 provinces were included. The model indicated that precipitation in the warmest quarter and poor socio-demographic index were the most significant risk factors affecting VL distribution. The risk map indicated that Brazil, Iran, Ethiopia, and India were the regions with the highest probability of infection. We estimated that 5.3 billion people live in regions at risk of VL.

Conclusions: VL is undergoing geographic expansion. Our study increases understanding of VL’s global-risk distribution and how risk factors influencing the disease transmission. Our findings may aid in promoting disease control in future surveillance activities.

This article deals with the optimization by simulation of a graded bandgap thin film solar cell based on antimony selenosulfide Sb2(Se1-ySy)3 having the following structure: Front contact/n-ZnO/i-ZnO/p-SbSSe/n-CdS/Back contact. The simulation is performed using SCAPS-1D software. The optimization process includes optimizing the bulk defect density, bandgap profile, material composition, thickness, and doping density of the absorber layer of thin film solar cell based on antimony selenosulfide Sb2(Se1-ySy)3. We found that for a bulk defect density below 1013 cm-3 , using an absorber material with a graded bandgap profile leads to an efficiency of 25.33 % (For a bulk defect density of 1010 cm-3 ) higher than that with a uniform bandgap profile. However, for a bulk defect density of 1013 cm-3 , both profiles provide almost the same maximum solar cell conversion efficiencies of about 13.6 %. Ultimately, for a bulk defect density above 1013 cm-3 , the graded bandgap profile is not useful, and a maximum solar cell conversion efficiency of 10.5 % (For a bulk defect density of 1014 cm-3 ) is achieved with a uniform bandgap profile. These optimization results help to improve the efficiency of low-cost fabricated thin-film solar cells.

In the last few years, there have been a great deal of discoveries and research made that has contributed to the development of Metal-based polymer nanocomposites. Electromagnetic shielding, energy storage devices, fuel cells, membranes, sensors, and actuators are just some of the many intriguing uses for Metal-based materials and their composites. Experiments using cyclic voltammetry investigated the super capacitive qualities of MnO2 nanoparticles, MnO2 nanoparticles that had been doped with nickel, and MnO2 nanoparticles that had been combined with Poly-vinyl-alcohol (PVA) and Polyvinyl-Pyrolidone (PVP). A method known as hydrothermal synthesis was used in the production of both the polymer nanocomposites and the nanoparticles. Analyses using Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) revealed the structural changes that occurred as a result of the interaction between MnO2/Ni and the PVA/PVP mix matrix. Examining the surface morphology of synthesized nanocomposite films was carried out with the assistance of scanning electron microscopy (SEM). Through the use of cyclic voltammetry, it was discovered that the values of capacitance for MnO2, nickel doped MnO2, and nickel doped Polymer capped MnO2 nanoparticles, respectively, were 164F/g, 293F/g, 304F/g, and 471.9F/g. In contrast to nickel doped MnO2 nanoparticles that were assisted by PVP, nickel doped MnO2 nanoparticles that were assisted by PVA were shown to be a more effective super capacitor.

Recent studies have produced stable inorganic perovskites that contain no lead, replacing lead-containing perovskites' risky and unstable properties. The present investigation thoroughly examined the electrical behavior, elastic characteristics, optical features, and transport properties of Li2CuTlZ6 (Z = Cl, Br, I) halides in order to discover potential applications. The Wien2k code was utilized to apply density functional theory (DFT) in order to clarify these physical properties. Using the generalized gradient approximation (PBEsol-GGA), we determined structural parameters through the energy optimization procedure that corresponded with the available data. Additionally, elastic parameters as well as formation energies ranging between -2.33 to -1.39 eV were used to validate cubic durability for the two halides. Moreover, the modified Becke-Johnson (mBJ) potential successfully provided precise direct bandgap values for all halides. According to this study, the shift in anions from Cl to Br is responsible for the reduction in band gap within the infrared spectrum. Our computed optical parameter findings show that Li2CuTlCl6 and Li2CuTlBr6 halides demonstrate excellent optoelectronic efficiency with low reflection, strong optical absorption, and conductivity. The investigation clarifies that the temperature-dependent character of the materials electrical transport properties is due to their very small bandgap. These materials may find use in thermoelectric applications, as evidenced by the almost unity of the obtained figure of merit, which points to their semiconducting behaviour.

Published: April 2024

New subgroups of patients with severe community-acquired pneumonia (SCAP) are hardly predicted by the use of clinical covariates; clusterization may signiﬁcantly improve diagnostic approaches and facilitate the adaptation of speciﬁc treatment modalities to patient’s individual characteristics.

The aim of the study. To identify linking the sepsis phenotype in patients with SCAP and preferable treatment option to forecasting the outcome and improve treatment results.

Materials and methods. Case histories of 664 of intensive care unit (ICU) patients with sepsis (2016–2023) from I. I. Mechnikov Northwestern State Medical University were analyzed. The study included 568 (85.5%) patients with viral SCAP (SCAPv group) and 96 (14.5%) patients with bacterial SCAP (SCAPb group). Sepsis phenotypes were identiﬁed using algorithm proposed by Seymour C.W. et al. In SCAP cases associated with COVID-19 infection (n=293, 51.6%) patients received genetically engineered biological therapy (GIBT). The study compared two cohorts of patients: those who received GIBT and did not receive GIBT. Data were statistically processed using the Statistica 10.0 and SPSS software packages.

Results. Analysis revealed 4 sepsis phenotypes: α- (N=323, 48.6%); β- (N=128, 19.3%); γ- (N=87, 13.1%); δ - (N=126, 19%). The majority of SCAPv group patients — 295 (51.9%) — had α-phenotype of sepsis, while δ -phenotype prevailed in the SCAPb group — 53 (55.2%). The proportion of patients receiving GIBT and exhibiting α- sepsis phenotype dominated over other sepsis phenotypes: 61.8% of patientspossesed α- phenotype, whereas β-, γ- and δ -phenotypes were determined in 16% , 12.6%, and 9.6% of GIBT patients, respectivelty (P<0.05). The best eﬀect of using monoclonal antibodies to interleukin-6 receptors as a GIBT was obtained in patients with the α-phenotype sepsis and COVID-19-associated SCAP: 87.5% favorable outcomes, P=0.0419. Rate of bacterial sepsis was signiﬁcantly lower in patients with α- and δ -phenotypes of sepsis receiving GIBT vs those who did not receive this therapy: 12.71% vs 23.2% of patients with α-phenotype, P=0.0131; 25.0% vs 70.41% of patients with δ -phenotype, P=0.0254, respectively.

Conclusion. Diﬀerences in sepsis phenotype between patients with viral or bacterial SCAP may stratify patients for diﬀerent therapeutic management and more accurately predict potential complications and unfavorable outcome.

The aim of the study was to compare the eﬀect of sevoﬂurane and chloral hydrate on the neurological status and volume of brain damage after trauma and ischemia in experimental models of traumatic brain injury (TBI) and focal ischemic stroke (IS) induced by photothrombosis (PT).

Materials and methods. The experiments were performed on mongrel Wistar rats weighing 250–300 g (N=43). There were 4 groups: the Ischemia + Sevoﬂurane group (ISSEV) (N=10), the Ischemia + Chloral hydrate group (ISCH) (N=10), TBI + Sevoﬂurane group (TBISEV) (N=13), and TBI+Chloral hydrate group (TBICH) (N=10). Ischemic brain damage was modelled using Rose Bengal (RB) dye-induced PT, and TBI was modelled using mechanical force-induced concussion.

Results. MRI findings indicate lower volumes of brain damage (mm³) in rats from TBISEV group compared with the TBICH group (19±5 vs. 60±5, P<0.0001), and in the ISSEV group compared with the ISCH group (9.8±1.5 vs. 21.5±2, P=0.0016). Moreover, there was a significant difference between ISSEV and ISCH groups based on the protocol assessment of neurological status on day 14 with higher scores in ISSEV (11.4±1.8 vs. 4.9±2.6, P<0.0001).

Conclusion. Taking into account the data obtained, we recommend a careful choice of anesthesia when modeling ischemic stroke and traumatic brain injury in animals. In particular, the neuroprotective eﬀect of sevoﬂurane should be taken into account in the PT and TBI models.

The paper proposes a framework for embedding logic programming and constraint programming methods in Scala by building a logical object-oriented language around the unification of typed logic based on monads. Two types of API are considered — high-level for language embeddings and low-level for organization of the bidirectional flow of data during the execution of logic programs. Differences in the capabilities of logical mechanisms can be expressed as subclasses of the class of unification monad types. This design makes it possible to share the implementation of custom unification between different frameworks and to use other languages’ embeddings in Scala from the declarative side. The monadic API provides the application developer with a simple and intuitive tool to implement custom logic within the unification. Our frameworks provide a clear representation of logical deduction: Scala code is only used for ad hoc unification. But the overall goal execution is an external interpretation that can implement different strategies. This design provides modularity and good integration with the rest of the ecosystem.

A large dataset (50 thousand comments) containing different reviews and sentiments was collected and annotated to successfully train and validate the model. It was also translated into Ukrainian language with the help of an automatic translator. The architecture of the neural network model underwent optimization to enhance classification outcomes. Furthermore, work was conducted on enhancing the user interface. The developed application was tested, and the results were demonstrated. The resulting model demonstrated accuracy 85% in determining sentiments. The implemented application has got basic design (which can be customized) and some settings for chatbot. Further improvement of the model’s classification quality can be achieved by collecting a larger and better organised dataset or by researching other RNN architectures.
Problems associated with creating special software for simulating of human physiological responses to dynamic accelerations
Authors:   Institute of Software Systems NAS of Ukraine, Grygoryan R.D.
Published: April 2024

Under extreme accelerations, human physiological mechanisms cannot provide adequate circulation. Special methods and devices protecting pilot’s brain and eye functionality have been proposed but their efficiency is individual and depends on pilot’s skills. Currently, the lonely technology to safely acquire and test the necessary skills is based on use of special centrifuges. However, lack of adequate data about physiological and biomechanical events are two main causes worsening the training results. Special computer simulators, capable to model and visualize the main mechanical and physiological effects occurring under dynamic accelerations, could increase the effectiveness of future pilot’s training process. This publication aims to define fundamental problems concerned with creating the required software. There exist two main groups of problems. The first group is concerned with the necessity to create basic mathematical models quantitatively describing both the physiological events and effects induced by protective maneuvers. Here special logical procedures, individualizing the basic physiological models, have to be proposed. The second group of problems is predominantly technical and associated with the necessity of special user interface (SUI) development. SUI must be subdivided into two functional sections – one for preparing a single computer experiment (simulation), and another – for analyzing the results of simulation. An experiment preparation includes the following events: i) a preliminary tuning of models according to biometrical data; ii) a setting of acceleration profile; iii) a choosing of protective algorithms and tools (or without protections); iv) a choosing of forms for results storage. Graphs presenting the dynamics of input and output variables are the main forms while the table forms are also included. The user (trainer or trainee) will be able to retrieve from the memory graphs of previous simulations to compare the effectiveness of additional protective elements. The software must be autonomic for the Windows platform.

Published: April 2024

The article considers the problem of low frequency signal classification, as sound or vibration pattern footprints may describe types of objects very well. In cases of a priori absence of object signal pattern information, the unsupervised learning methods based on clustering looks good enough for classification, and outperform neural net-based methods in case of limited power envelope. We have used big real-world sound and vibration data set to check several clustering methods (K-Means, OPTICS) for classification without any a priori data and have got good enough results. The article considers data set preparations including primary signal processing and the parameters to select appropriate clustering algorithms, which depends on input data shape. There are several examples of data classification, also cascaded methods for data set improvement are considered. Finally, we provide a good and practical guide for exploring low frequency signals using clustering methods, which can be used for real world observations and analysis for open space and inside buildings.

The paper describes the analysis of the problems of using microservice architecture in distributed systems. Emphasis is placed on flexibility in the choice of technologies, scalability and organization of teams working on given microservices, technical and domain problems of transaction implementation in comparison with a monolithic system. The main focus is on transactions, as they ensure atomicity, consistency, isolation, and persistence across multiple services. In the process of analyzing modern approaches and solutions for working with transactions in distributed systems, it was found that one of the effective solutions is the use of the Transactional Outbox pattern. Its implementation in the form of Spring starter is presented. The latter is added to the system, configured and facilitates the use of transactions and the publication of events that are part of a transaction in a microservice architecture. The developed methodology for implementing distributed transactions based on message queues, using the above-mentioned starter, is described in detail. The basic configurations and settings of message queues for the correct operation of transactions in distributed systems are defined

Indoor Air Quality (IAQ) is a significant health determinant in the building environment. Ventilation plays a significant role in providing comfortable working conditions and securing contaminant removal from indoor spaces. The heat and effluents generated by cooking activity need to be exhausted from the kitchen space to control the IAQ and provide thermal comfort. The study investigates the ventilation performance concerning IAQ of five institutional kitchens in an educational campus. This study evaluates the influence of building parameters on ventilation performance and IAQ using experimental research and Computational Fluid Dynamics (CFD). The empirical part includes field measurement of indoor airflow and IAQ indicators (particulate matter, CO2, temperature, and RH). The Integrated Environmental Solutions Virtual Environment (IESVE) software performs the CFD analysis. The 'Local Mean Age of air' (LMA) is used as a parameter to analyze IAQ. The findings reveal that the LMA reduces with increased cross-ventilation at the operational level and the presence of local exhaust ventilation, such as chimneys. Moreover, a higher slenderness ratio, lower aspect ratio, and lower building volume reduce the age of air.

Analysis of the separation process in a vortex chamber is based on the assumption of phase equilibrium existence in the system. Dynamic processes occurring while phases moving in a vortex chamber contribute to the separation of the liquid and gaseous phases of hydrocarbon mixtures. Thus, the transition of the fluid to a metastable state in the vortex chamber will occur in less time than using the traditional methods.Based on the developed model of a vortex chamber in ANSYS FLUENT a series of numerical experiments were carried out. The influence of various parameters on the amount of removal of liquid and gaseous phases of hydrocarbon mixtures was determined. Indicators of the properties of the liquid phase have the greatest impact on the dynamics of the removal of liquid with gas, while the characteristics of the gas phase can be neglected due to their statistical insignificance.When studying the design of a vortex chamber, the smallest removal is observedwhen the inlet pipe is installed further from the top of the chamber (more recessed into the flow). The H/D ratio has less influence, but the offset decreases monotonically as the H/D parameter increases. The influence of the flow rate and the ratio of phases formed in the nozzles on the amount of carryover indicates that with an increase in the gas phase in the incoming flow, the removal of liquid increases. The inlet rate has a less influence.Statistical processing and regression analysis of the results of numerical modeling were carried out. Empirical equations for calculating the amount of droplet liquid removal from the vortex chamber are obtained. The dispersion value was calculated and the significance of the regression coefficients was checked. Based on the results of assessing homogeneity, reproducibility, and adequacy, a conclusion was made about the suitability of the developed model for calculations.

Published: April 2024

The creation and development of technology for the production of highly effective environmentally friendly inhibitors is an important area for modern low-tonnage chemistry and the oil and gas industry. The application of the principles of «green chemistry» and circulation economics in this matter makes it possible to reduce the cost of production of inhibitory compositions by using waste or excess production of organic compounds as raw materials. One of these classes of compounds are ketones and their derivatives, the production of which is common in small- and large-tonnage chemical enterprises. Poorly studied ketone derivatives are ketoximes, a product of the interaction of ketones and amino compounds; an important advantage in the context of studying the inhibitory properties of ketoximes is the presence in their structure of the functional group C=N –OH with electronegative N, O atoms and a double bond at the same time, which have good solubility in water, are nontoxic and biodegradable. Selected compounds, in particular butanone oxime (methyl ethyl ketoxime), which is a fairly common organic compound used in industry to inhibit the polymerization process. The effect of a number of ketoximes (with a C4 chain length) on the corrosion resistance of carbon steel in an imitation of NACE formation water saturated with carbon dioxide and hydrogen sulfide has been studied. The influence of medium temperature and exposure time on inhibitory properties has been established. The influence of the «structure – property», kinetic and physico-chemical parameters of interaction, as well as the mechanism of adsorption on the metal surface are investigated.

Published: April 2024

The relevance of the work is based on the growing interest in popular science journalism. At the same time, there is a lack of research into the area of scientific history popularization of. This work is devoted to the study of hypermedia text dedicated to the invention of radio. The empirical base consists of publications on the dzen.ru platform, as well as comments from platform users. The category of objection creates polemic. The intentional-stylistic characteristics of objection in the fields of implication and involvement are determined. The following models of objection have been identified: for implication — an objection as a tool for searching for truth, as a means of confirming semantic position; for involvement — manifestation of a semantic position, frustration, refusal to argue. A system of linguistic means of objection marks the selected models. The most active and potentially effective means are particles and conjunctions. These means indicate the instrumental nature of the objection. In the field of implication, lexemes with the semantics of doubt and opposition were found. Emotionally expressive vocabulary was found in the field of involvement. If the vocabulary of an objection contains an ideological component, then the type of objection can be distinguished: frustration. It goes beyond traditional popular science communication. On the contrary, the use of ameliorative assessments allows us to speak about the desire of the participants to harmonize communication. However, the effectiveness of such aspiration in the hypermedia text under study turns out to be extremely low. The study will be useful to media theorists. It will expand the subject field of research in popular science journalism. The work will also be useful to practitioners who talk about conflict-prone scientific topics in the media space.
Thematic Diversity of Regional News on the TASS News Feed
Authors: Sinyakova Ekaterina
Published: April 2024

The article is devoted to the problem of thematic diversity of news content from the regions of the Russian Federation. Based on the agenda setting theory and its special direction “media diversity”, the author explores approaches to its measurement and operationalizes this concept in the context of the TASS regional editorial policy. The presented results of the content analysis allowed to draw conclusions about topics dominated the agency’s agenda for 10 years. Thematic priorities of news from various federal districts have been identified. Quantitative assessments examine the dynamics of the thematic spectrum, both for the country as a whole and at the level of macroregions. The conclusions are drawn that the concept of the agency's regional editorial policy, focused on the maximum variety of content and the disclosure of the information potential of the regions, is not fully implemented in practice, which, in particular, is expressed in an excess of news about emergency and criminal incidents. Nevertheless, the editors were able to introduce into routine practice active information support for topics chosen by the Russian government as strategic, which indicates the flexibility of the agency’s agenda and the potential for greater diversity. In interpreting the data, the author also relies on his own experience as a correspondent and editor of a news agency.

Published: April 2024

In the article, the authors continue to present the results of a study of the current state and possibilities for improving the editorial strategies of municipal newspapers. The crisis of (self) identification of local media is observed in many countries, but in Russia there is a possibility of closing a large number of local media, which, in fact, are not needed by the government and business, and citizens are not ready to participate in financing their activities. However, there is also a positive experience of some successful regional newspapers, which is possible for dissemination. The article presents the results of the analysis of interviews with the leaders of such media. Emphasis is placed on the role of local media in public processes in which other actors also participate. The authors draw attention to the uniqueness of the work of local editorial offices, which is associated with a long-term focus on solving the problems of citizens and communities and the desire to work together with readers, government officials and business to solve urgent problems. The authors of the article propose to open a discussion about the criteria for the effectiveness of local media and offer their own version of kpi: not newspaper circulation and social media coverage, but real changes that have occurred on the initiative and (or) with the participation of local media journalists.

Authors: Dolgova Yulia
Published: April 2024

In the context of global turbulence, the importance of journalists understanding their mission and motivation to implement the functions of the media as a social institution is growing. In this paper, attention is focused on the study of ideas about the functions of future television workers studying at the specialized department of the Faculty of Journalism of Lomonosov Moscow State University. The survey showed that students are primarily focused on the implementation of the traditional triad of functions: informational, entertainment and educational. The majority of respondents saw their major task as informing the audience, which they understood as the main and most important task of the media. The second most popular was the entertainment function, the importance of which the students have proved to be a feature of the modern media space, where news can be learned from digital media, while television is used for recreation and entertainment. As a priority, students also often referred to the cultural and educational function, which contributes to the development of both the individual and society. The study also demonstrated the growing attention of students to the function of public opinion management. The social value of investigative journalism and the importance of implementing the control function of the media were noted in several responses, but were not in demand. The respondents justified not only the importance of a managerial function, but also an entertainment, cultural and educational one, believing that journalists should help viewers distract from the agenda.
Spor Bilimleri Fakültesi Öğrencilerinin Elektronik Spor Tüketimine Yönelik Metaforik Yaklaşımları

Published: April 2024

Teknolojik gelişmeler, spor endüstrisinde önemli değişimlere yol açarak birçok yeni kavramın ortaya çıkmasına neden olmuştur. Özellikle son 20 yılda hayatımıza giren dijital oyunlar, sporla iç içe geçerek spor endüstrisine devrim niteliğinde bir yenilik getirmiştir. Bu dijital oyunlar, e-spor adı altında önemli bir endüstri haline gelerek büyük bir ekonomiyi sürüklemekte ve global çapta insanları bir araya getiren organizasyonlara ev sahipliği yapmaktadır. Ancak, literatürde e-spor için yapılmış metaforik araştırmaların eksikliği, bu alandaki zihinsel deneyimleri anlamak ve açıklamak konusunda bir boşluğu işaret etmektedir. Bu bağlamda, Spor Bilimleri Fakültesi öğrencilerinin e-sporu nasıl algıladıklarını inceleyen bu çalışma, nitel araştırma yöntemini benimsemiş ve metaforik bir araştırma yaklaşımını tercih etmiştir. Toplamda 423 öğrencinin katıldığı araştırmada, 333 öğrencinin verileri değerlendirmeye alınmıştır. Araştırma, katılımcılara yöneltilen demografik bilgiler içeren kişisel bilgi formu ve e-spor tüketimine dair metaforik yaklaşımları belirlemeye yönelik yarı yapılandırılmış görüşme formu kullanılarak gerçekleştirilmiştir. Sonuç olarak elde edilen veriler, e-sporun popülerliğinin artmasına rağmen, spor endüstrisi içinde hala e-sporun spor olarak nasıl kabul edildiği konusunda belirsizlikler bulunduğunu göstermektedir. Spor Bilimleri Fakültesi öğrencileri arasında e-sporun bir spor dalı olarak kabul edilip edilmediği konusunda şüpheler olduğu görülmüştür. E-spor tüketimi genellikle hedonik bir tüketim yaklaşımı olarak algılanmakta olup, müsabakaya dayalı metaforların eksikliği dikkat çekmektedir. Bu durum, ilerleyen süreçte e-sporun daha çok rekabet, kazanma, egzersiz gibi spor etkinlikleriyle ilişkilendirileceği düşüncesini ortaya koymaktadır.

We studied snowbed communities in place of long-lying snow in the typical and southern tundra subzones of the East European sector of the Arctic. Three new associations (Salicetum herbaceae-polaris Lavrinenko et Lavrinenko ass. nov., Salici polaris–Sibbaldietum procumbentis Lavrinenko et Lavrinenko ass. nov. and Myosotido asiaticae–Salicetum polaris Lavrinenko et Lavrinenko ass. nov.) on siliceous substrates united into a new alliance Veronico alpinae–Salicion polaris Lavrinenko et Lavrinenko all. nov. in order Salicetalia herbaceae and class Salicetea herbaceae. One new association (Pinguiculo alpinae–Salicetum reticulatae Lavrinenko, Lavrinenko et Neshataev ass. nov.) on stabilized calcareous soils is placed in a preliminary alliance Carici parallelae–Salicion reticulatae Lavrinenko, Lavrinenko et Neshataev prov. in order Arabidetalia caeruleae and class Thlaspietea rotundifolii. Table analysis, cluster analysis of relevés and syntaxa and analysis of association coenofloras from East European tundra, from mountainous areas of Northern Europe and from Arctic Siberia confirm the reliability of defining new alliances.
Session Quality in Psychotherapy and Counseling: A Narrative Review of Assessment Methods and Main Characteristics
Authors: Sukhorukov S.D. , Golovanova I.V. , Zhukova M.A.
Published: April 2024

Defining a high-quality psychotherapy or counseling session is important but challenging due to the lack of consensus in the scientific community. Presently, there is no clear definition or universally accepted criteria for determining session quality. This article presents a narrative review of contemporary literature on universal methods for evaluating the quality of individual psychotherapy and psychological counseling sessions. This review aims to identify prevalent and valid instruments for assessing session quality and to define the main characteristics of a high-quality session. The Session Evaluation Questionnaire, Session Evaluation Scale, Session Impacts Scale, and Individual Therapy Process Questionnaire encompass the predominant methods found. This study explores the structure, applications, psychometric properties, strengths, and weaknesses of each tool and provides recommendations for their utilization in examining session quality. The article also comprehensively examines the characteristics of high-quality sessions embedded within these methods. High-quality sessions are based on a trusting relationship in which the specialist respects the client's self-sufficiency and avoids imposing his/her beliefs or actions. To improve the quality of sessions, the therapist or counselor should emotionally support the client, encourage hope, actualize strengths, develop inner resources, help reframe and overcome difficulties, explore new perspectives and meanings, and increase overall awareness of motivations for behavior.
