Published: March 2024

The existing technical level analysis of the polymeric materials requirements determination for waterproofing of the bridge structure carriageway slab is carried out. Nowadays new durable sprayed materials based on isocyanate: polyurea, polyurethanes, polycarbonates find mass application in transport construction. The waterproofing layer is applied on the priming layer by hot spraying method using special equipment, with the formation of a strong, elastic, seamless, waterproof coating, which when applied reproduces the shape of the geometry of the insulated surface.

To ensure the service life, recommendations for improving the bridge structures sprayed polymer waterproofing technology at low temperatures are developed.

The technological solution providing the directed thermophysical regulation of bridge structures roadway slab sprayed polymer waterproofing based on the isocyanates at low temperatures on the basis of prevention and elimination defects (caverns) point is presented.

The technical and economic calculation confirming the sprayed waterproofing technology application efficiency in comparison with traditionally used roll materials have been carried out. Due to the new technology application, the number of current repairs is reduced from 24 to eight for a range of 49 years. By calculation means using the programme developed by the author, the discounted payback period for the sprayed polymer waterproofing technology was established at the beginning of the 17th year.
Application of fuzzy logic algorithms for predicting the pipe-culvert technical condition on railways
Authors: Ryumin Maksim
Published: March 2024

This article is part of the author’s dissertation research in the field of developing a methodology for predicting the pipe-culvert technical condition on railways using the mathematical apparatus of fuzzy logic.

One of the common methods for assessing engineering structures is the point rating method. During the examination, each identified defect is assigned a certain number of points. Then the number of points is summed up according to the developed methodology and, based on the obtained result, a conclusion is drawn about the condition of the object.

However, in conditions of significant subjectivity and limited input data, the issue of predicting the structure technical condition is quite labor-intensive.

As an addition to existing methods for predicting the structure technical condition, in particular pipe-culvert, it is proposed to apply a method based on the fuzzy logic principles, which is a generalization of fuzzy logic and set theory. In fuzzy logic, unlike classical logic, instead of the values true and false, the truth value degree is used, which takes any value from an infinite set from 0 to 1 inclusive.

To predict changes in condition and determine the deterioration rate of the technical characteristics of a pipe-culvert, it is necessary to create a model in which scoring methods are transformed into estimates presented in terms of fuzzy logic.

The article presents a methodology for using fuzzy logic algorithms to predict the pipe-culvert technical condition on railways.

As a result of the research, numerical gradations of the term «pipe-сulvert Age» were obtained. With limited and subjective input data, expressed numerically in terms of fuzzy logic — «pipe-culvert Age» and «pipe-culvert Condition», it is possible to calculate the values of the term «pipe-culvert Degradation Rate».

The author presents a method for predicting the technical condition of railway pipe-culverts, based on the principles of fuzzy logic, founded on fundamental set theory.

The developed mathematical model makes it possible to calculate the structure transition time from one technical state to another.

To implement fuzzy logical inference of the presented model, the Fuzzy Logic Toolbox package is used in the MATLAB software environment.
Stress-strain state analysis of the polymer insulator adhesive bonding of a railway overhead system with a metal insulation displacement contact under torsion
Authors: Zharinov Mikhail , Marasanov Alexander
Published: March 2024

Based on consideration of a simplified model, an analytical solution to the problem of adhesive bonding stress-strain state estimation of a polymer insulator of the railway overhead system with a metal insulation displacement contact under torsion is presented. The polymer insulator is made of unidirectional epoxy resin-based fibreglass with the ratio of binder and filler 0.3:0.7. The solution is obtained by considering the adhesive bonding incremental element equilibrium.

The influence of such parameters as the thickness of the adhesive layer, the adhesive bonding length, and the modulator of shearing of the metal insulation displacement contact on the adhesive bonding stress-strain state change has been investigated. It is shown that the greatest tangential stresses in the adhesive layer occur at the point of entry of the fibreglass rod into the steel termination, and the length of the zone of relatively large tangential stresses in the adhesive layer is a small value compared to the length of the adhesive bonding. During the research of influence of glue layer thickness on the greatest tangential stresses in a glue layer it is received, that at accepted parameters of a glue bonding increase of thickness of a glue layer in ten times leads to reduction of the greatest tangential stresses in a glue layer approximately in three times. An increase in the length of the adhesive bonding, all other things being equal, has little noticeable effect on the greatest tangential stresses in the adhesive layer. The same conclusion can be reached by varying the shear modulus of the metal termination. Thus, replacement of steel insulation displacement contact with copper or aluminium insulation displacement contact practically does not change the value of the greatest tangential stresses in the adhesive layer.

Published: March 2024

O objetivo desta pesquisa visa analisar o que caracteriza uma mulher em vulnerabilidade, quais tipos de vulnerabilidade podem existir no universo feminino e quais fatores levam as mulheres a permanecerem em vulnerabilidade. O estudo analisou a atuação da mulher no mercado de trabalho e o empreendedorismo feminino como ferramenta estratégica para mulheres em vulnerabilidade. O método utilizado foi uma pesquisa bibliográfica com abordagem qualitativa e de natureza exploratória, a partir de estudos científicos e dados sobre mulheres em vulnerabilidade que possuem dependência financeira, a atuação da mulher no mercado de trabalho e o papel do empreendedorismo como ferramenta para gerar renda e alcançar independência financeira. Os resultados apontam um encontro inédito sobre os doze tipos de vulnerabilidade feminina, o número expressivo de mulheres nessa realidade com consequências negativas, inclusive aumento da taxa de feminicídio, mesmo em um contexto em que a mulher busca mais conhecimento e desenvolvimento de habilidades e competências por meio do ensino superior, mas que não implica em compatibilidade com os homens tampouco contribui com a diminuição do número de mulheres em estado vulnerável. Descobriu-se ainda que o empreendedorismo, apesar de ser realizado em sua maioria por necessidade, é um caminho para gerar renda e independência financeira feminina.
TEMPERATURE CORRECTION METHOD OF RADIATION THERMOMETER BASED ON THE NONLINEAR MODEL FITTED FROM SPECTRAL EMISSIVITY MEASUREMENTS OF Ni-BASED ALLOY
Authors: Xu Yanfen , Zhang Kaihua , Yu Kun , Liu Yufang
Published: March 2024

Accurate temperature monitoring of heat transfer tube is crucial for safe and efficient operation of nuclear power
plants, and radiation thermometer is a common method used for this purpose. This paper thoroughly introduces the
measurement principle of the radiation thermometer with an operation wavelength range of 8-14 μm. The spectral
emissivity of Ni-based alloy DD6 under argon condition is measured using an emissivity measurement setup
equipped with a Fourier-transform infrared (FTIR) spectrometer. By integrating the spectral emissivity in the working wavelength range, the spectral band emissivity can be calculated to enhance the accuracy of calculation results obtained by radiation thermometer. And curve of the spectral band emissivity with temperature can be accurately described
by the nonlinear model. The radiation and corrected temperatures are compared with the temperatures obtained by a K-type thermocouple to verify the availability of the spectral band emissivity obtained by fitting the nonlinear model. The temperature comparison results demonstrate that the corrected temperatures are closer to the true temperature than the radiation temperature, with a maximum temperature deviation of only 4.38°C. The combined relative uncertainty of true temperature measurement by the radiation thermometer at temperatures of 200, 300, 400, and 500°C is less than 3.60%.

Published: March 2024

This study aimed to evaluate the contact activity of the essential oil derived from Mentha piperita L. (Lamiaceae) against two significant stored product pests, namely Tribolium castaneum (Herbst, 1797) (Coleoptera: Tenebrionidae) and Sitophilus granarius (Linnaeus, 1758) (Coleoptera: Dryophthoridae), in a controlled laboratory setting. For this purpose, concentrations of 0.05, 0.1, and 0.15 µl/insect of plant essential oil were applied to stored product pests using a microapplicator. Dead insects were counted at 24, 48, 72, and 96 hours after application. As a result of the study, the essential oil demonstrated contact activity at varying rates depending on the applied pest and dose. After 24 hours, the 0.15 µl/insect application dose was the most effective against T. castaneum, resulting in a 23.6% mortality rate; after 96 hours, this rate increased to 33.4%. The essential oil exhibited greater contact activity on S. granarius, resulting in a 93.4% mortality rate after 24 hours when administered at a concentration of 0.15 µl/insect. At the end of 96 hours, the mortality rate at the same dose was found for S. granarius to be 98.2%. In addition, the effect of essential oil on the germination power of wheat grain was examined at doses of 2, 5, 10 and 20 μl/Petri under laboratory conditions. 73.8% of the seeds germinated at the maximum dose of 20 µl/Petri, while 99.4% germinated at the minimum dose of 2 µl/Petri. The research findings indicate that the essential oil of M. piperita possesses the capacity to be employed for the management of S. granarius.
On the Multi-Polarity and Transformation of the International Payment System
Authors: Kubasova Tatiana , Chepinoga Oksana
Published: March 2024

In the modern world economy, a global transformation is taking place, a transition is being made from a unipolar world order to a multipolar one. An analysis of the economic literature indicates the absence of a unified approach to assessing the ongoing changes. The article summarizes the views of experts on this process. The transition to multipolarity, the formation of new centers of power, the hegemon's loss of its position lead to a gradual decrease in the role of the US dollar in the world monetary system as a reserve asset and a means of international settlements. The sanctions imposed on Russia contributed to the development of the process of moving away from the dollar and switching to other currencies in international payments. The authors analyzed the evolution of the de-dollarization process, which has been actively developing in recent years, and the factors influencing it. The article summarizes and analyzes scenarios for creating an international payment and settlement unit.
Relations as Immunity: Building Community Resilience
Authors: Kenney Martha , Müller Ruth
Published: March 2024

Resilience—a term that originated in mathematical ecology—now commonly refers to the ability to thrive in the face of trauma and adversity. This Position Piece reflects on both the charisma and political lability of resilience in the early 21st century. On the one hand, resilience is easily compatible with neoliberal discourses that demand that individuals protect themselves in the absence of state or community support. On the other hand, resilience can be an important corrective to narratives about the damage caused by trauma, focusing attention on our innate ability to heal. We argue that the ambivalence of resilience requires theoretical and empirical attention to both the wider appeal of the term and the situated definitions deployed by diverse actors. In particular, we look at the rise of the term ‘community resilience’ popularised by academics, community leaders, and activists, which seeks to avoid the pitfalls of the neoliberal definition of resilience and argues that strong interpersonal relationships can support health equity. Despite the ambivalence of resilience, we find “community resilience” to be promising in a time when collective visions of health and immunity are desperately needed.
How to Categorise Disease? Endometriosis, Inflammation, and ‘Self Out of Place’
Authors: Ford Andrea Lilly
Published: March 2024

Endometriosis is a condition where tissue similar to the uterine lining develops outside the uterus; it ‘bleeds’ during periods, forms lesions, and causes chronic pain. Despite affecting around 10% of menstruating people, its aetiology is poorly understood, and diagnostics and treatments are highly inadequate. Current efforts to reconceptualise the disease generally centre around inflammation. In this Field Note I describe my fieldwork during the pandemic, which was largely based on in-depth interviews with patients and clinicians in and around Edinburgh, Scotland. This research interrogates the socio-cultural context in which endometriosis is changing from a ‘gynaecological disorder’ to a ‘systemic disorder’ implicating the endocrine system (a ‘hormonally driven condition’), the neural system (‘neuropathic pain’) and/or the immune system (an ‘inflammatory condition’). It explores how the lived experience of endometriosis challenges ingrained ways of thinking about the body and bodily ‘systems,’ which are reflected in the design of healthcare systems. Considering endometriosis alongside changing conceptions of immune response invites thinking beyond self-versus-non-self (as in older concepts of immunity), and self-attacking-self (as in auto-immune conditions), to something like ‘self-out-of-place,’ simultaneously calling into question the suitability of our social and material relations.

Authors:   Khakass State University named after N.F. Katanov, Eremeeva Olga
Published: March 2024

The article is devoted to the problem of a lack of a comprehensive source of information about the territory for investors. The possibilities of the investment passport in informing businesses about the territory are evaluated. The information requests of investors about the territory are determined on the basis of research by scientists-economists and business experts. The experience of existing investment passports in ten regions of the Siberian Federal District and the complex investment project "Yenisei Siberia" was analyzed. The list of quantitative and non-quantitative indicators of investment passports is compiled. The opportunities and weaknesses of statistical accounting in informing investors about the territory are shown. It is noted that in the regional statistics there are no indicators for the sections: natural resources, energy infrastructure, foreign economic activity, and existing investment projects and proposals. The article defines the composition of indicators of information about the territory that are necessary for the business community to make managerial decisions regarding the activities in the territory. It is proposed to include these indicators in the system of integrated reporting of the territory as a comprehensive source of information for different categories of users. Information for investors is classified by the territory's capitals: human, socio-infrastructural, natural, production and financial. The allocation of the territory's capitals is based on the International Fundamentals of Integrated Reporting. Reliable multifaceted information about the territory as part of integrated reporting will allow for long-term relations with investors.

Published: March 2024

The objective of this research is to present a comparative analysis using various lengths of time windows (TW) during emotion recognition, employing machine learning techniques and the portable wireless sensing device EPOC+. In this study, entropy will be utilized as a feature to evaluate the performance of different classifier models across various TW lengths, based on a dataset of EEG signals extracted from individuals during emotional stimulation. Two types of analyses were conducted: between-subjects and within-subjects. Performance measures such as accuracy, area under the curve, and Cohen's Kappa coefficient were compared among five supervised classifier models: K-Nearest Neighbors (KNN), Support Vector Machine (SVM), Logistic Regression (LR), Random Forest (RF), and Decision Trees (DT). The results indicate that, in both analyses, all five models exhibit higher performance in TW ranging from 2 to 15 seconds, with the 10 seconds TW particularly standing out for between-subjects analysis and the 5-second TW for within-subjects; furthermore, TW exceeding 20 seconds are not recommended. These findings provide valuable guidance for selecting TW in EEG signal analysis when studying emotions.

Published: March 2024

Understanding the atmospheric properties and patterns is crucial in empowering Malaysia's national aerospace blueprint, national space, and legislation. While various policies have been enacted and implemented, there is a lack of information on the wind profile, specifically the upper air across Peninsular Malaysia. Realising the need to establish a standard guideline for national reference, future research, space-aerospace application, and legislation, this study was performed to develop the first wind profile analysis of upper air in Peninsular Malaysia. Relevant data from the Malaysian Meteorology Department was collected for analysis and evaluation. Specifically, a meteorology balloon attached with a sounding radiosonde was used to record data at 0000UTC (0800 h LT) and 1200UTC (2000 h LT) on the 15th day of each month for 7 years (from 2015 to 2021) at the KLIA and Kuantan Meteorology Stations for the wind profiling analysis. The daily overall data collection was recorded accurately once the balloon's rising rate stabilises from vertical air current (katabatic or anabatic winds). Subsequently, the collected data were evaluated in terms of the minimum, maximum, and average wind speeds for each year and time. Finally, the average wind speed of each year and time were combined to generate the Peninsular Malaysia wind profile. Based on the results, the projected wind profile for both stations identified three peaks of discrete sine wave flow type with low-speed wind profile in Peninsular Malaysia. The three peaks amplified the highest air velocity, whereby the 1st and 2nd peaks were located at the troposphere layer from 9,000 m to 12,000 m altitude (average wind speed of 10.8 ms-1) and 12,000 m to 18,000 m altitude (average wind speed of 13.7 ms-1). The 3rd peak was located at the stratosphere layer from 18,000 m to 32,000 m altitude (average wind speed of 15.2 ms-1). Since East Malaysia is located on the same equatorial line, the wind profile is hypothetically the same and exhibits only slight differences. In short, the established wind profile of upper air in Peninsular Malaysia in this study would facilitate other future studies and assist long-term planning of Malaysia's airspace legislation.

Published: March 2024

In an effort to address labor scarcity and enhance the cropping index in tidal swamp areas, farmers utilize direct seeding techniques. However, flooded conditions due to tides and ebb can hinder seed germination. This study aimed to obtain the best invigoration treatment for improving seedling establishment and growth in South Sumatra's tidal swamp hotspots. In the first part of the study, 19 different seed treatments were tested on the swamp rice variety, Inpara 9, in a greenhouse. These treatments included hardening, priming, thermal treatment, and controls. Soluble sugar content and α-amylase activities of treated seeds were analyzed in the lab. The results showed that the invigorated seeds outperformed the control group in terms of seedling growth and development when they were planted directly in the ground under both anaerobic germination (AG) and anaerobic germination with extra FeSO4 added to the soil (AG+Fe) conditions. All treated seeds also exhibited higher soluble sugar and α-amylase activities. A follow-up experiment in a hotspot area assessed the effectiveness of the top nine seed treatments from the first experiment under AG conditions. The flooded level was managed at around 10 cm during the experiment and Inpara-9 was the variety planted. All invigorated seeds exhibited superior seedling establishment and growth compared to the control on in-situ swampy land. Hardening using Trichoderma yielded the highest seedling establishment and performance, indicated by greater root and shoot dry weight than other treatments, followed by hardening with Methylobacterium td-J7 and Methylobacterium td-tpb3.

Lentiviruses are a highly robust gene delivery system capable of in vitro and in vivo gene transfer into multiple cell types. Recent fourth-generation lentiviral systems have been designed for enhanced safety, however, the increased recombination events required to produce infective lentiviral particles may reduce production efficiency. A set protocol for all types of target cells is not recommended and optimization of conditions for gene transfer into different target cells is required. In this study, we aim to evaluate the efficiency and reproducibility of lentiviral production using a fourth-generation lentiviral packaging system and identify optimal parameters for successful transduction in two different cell models, adherent and suspension cells. Lentiviral production, effect of viral volume, sustained gene expression and transduction adjuvants on adherent and suspension gene- cell models were evaluated. Transfection and transduction efficiency of lentiviruses was evaluated by fluorescence microscopy and flow cytometry. This study demonstrates that production of green fluorescent protein (GFP)- lentiviruses using the fourth-generation lentiviral packaging is consistent and reproducible. Optimal transduction of adherent cell types is achieved at lower multiplicity of infection (MOI) compared to suspension cells and produces GFP-expressing cells with higher intensity. Expression of GFP is sustained in all cell types over multiple passages. Polycation DEAE-dextran was determined to improve transduction in suspension cells, however, provides similar transduction efficiency as polybrene in adherent cells. In conclusion, fourth generation lentiviral system reproducibly generates high titre lentiviruses capable of infecting multiple cell types, however transduction protocols for different cell types require further optimization.
Proteomics Reveals the Role of Paederia scandens in ameliorating Non-alcoholic Fatty Liver Disease in a Rat Model

Published: March 2024

This study was conducted to evaluate the effect of Paederia scandens on high-fat diet­induced non-alcoholic fatty liver disease (NAFLD) in a rat model and further show the therapeutic mechanisms of Paederia scandens. Thirty rats weighing 180 ± 12 g (6 weeks old) were randomly divided into three groups: A control group (CG), a high-fat diet model group (HF), and a Paederia scandens intervention group (PS). After 45 days, the rats' serum lipid metabolism, liver injury parameters, and liver proteomics were detected. The results indicated that dietary Paederia scandens significantly reduced the levels of triglycerides, total cholesterol, glucose, and low-density lipoprotein cholesterol in the NAFLD rats compared with those in the HF group. Meanwhile, decreased levels of alanine aminotransferase and aspartate transaminase were observed in rats of the PS group. In addition, 382 differentially abundant proteins were identified between the HF and PS groups. Protein-protein interaction network analysis identified 14 keystone proteins that might play critical roles in ameliorating NAFLD. In particular, Paederia scandens treatment significantly upregulated the levels of Hadh, Hadhb, Acadl, Acox1, Acox3, Cyp3a2, and Cyp1a1, which are involved in fatty acid β‑oxidation, PPAR, and cytochrome P450 signaling pathways. Hence, the data demonstrated that Paederia scandens ameliorates hepatic lipid accumulation and impairment by enhancing fatty acid β-oxidation and activating PPAR and cytochrome P450 signaling pathways. These data provide new insights into the treatment of NAFLD and suggest the potential of Paederia scandens as an effective therapy.

Published: March 2024

The purpose of the publication is to highlight the activities of S. Kulzhynskyi in the process of gathering a collection of pysankas for the Lubny Museum of K. M. Skarzhynska, as well as to prepare for publication the famous album-catalogue «Description of the Collection of Folk Pysankas» (1899) through the prism of scientific and epistolary heritage. At the same time, the main task is to introduce it into scientific circulation; to replenish the source and historiographical base. The scientific novelty of the study is that it is the first to introduce the epistolary heritage of S. Kulzhynskyi related to the preparation for the publication of an album-catalogue of the collection of pysankas into scientific circulation. The late nineteenth and early twentieth centuries were marked by a significant rise in interest in Ukrainian folk art, including pysanka. Many researchers developed programmes for collecting information about pysankas, and private and museum collections began to form. In a short period of time, a number of publications by such well-known researchers as M. Sumtsov, V. Yastrebov, M. Korduba, and others were published. However, the most noteworthy is S. Kulzhynskyi's work on the formation of the collection of pysankas in the Lubny Museum of K. M. Skarzhynska and its processing with the subsequent publication of the catalogue. His work is still of interest to researchers today. The album-catalogue also became a source of knowledge and revival of pysankas in Ukraine in the late twentieth and early twenty-first centuries for many pysankas masters. The formation of S. Kulzhynskyi's views on pysankas and his desire to work on the collection's catalogue are revealed to some extent by his letters to M. Sumtsov, which are reproduced in the appendices. They provide information about the work on the catalogue, the problems faced by the author, etc. In the future, it is worthwhile (if possible) to find and publish M. Sumtsov's letters to S. Kulzhynskyi, which would reveal the famous ethnographer's comments to the author of the catalogue on its publication and the extent to which the latter listened to his advice and suggestions.

The purpose of the publication is to represent, through the prism of people's fate, the tragic history of the Meskhetian Turks, who were deported to the republics of Central Asia by the totalitarian communist government in 1944 from their historical homeland – Meskhetia in southern Georgia. In 1989, due to an inter-ethnic conflict artificially created by the soviet authorities, they were forced to flee and leave their homes for the second time. Having settled mainly in Donbas, they again became forced migrants, this time due to the beginning of the russian-Ukrainian war in 2014 and the large-scale invasion of the russian federation into Ukraine in 2022. It is emphasized that, despite everything, for many centuries Meskhetian Turks have preserved their customs and culture. It must be emphasized that the soviet past had a negative impact on the development of the community. The respondents provided important information about the deportation, the crimes of the soviet and russian authorities against the Meskhetian Turks, their life and daily life in the territories of Georgia, Central Asia (Uzbekistan, Kazakhstan, Kyrgyzstan), Ukraine (Donbas), the attitude of the local population, education, religion, peculiarities of preservation of customs, traditions and culture, quantity and many other things.

This study focused on the discovery of new drug candidates effective against the monkeypox virus. Virtual screening was performed to evaluate the potential of chili pepper natural products against homology-modeled DNA-directed RNA polymerase of the monkeypox virus using molecular docking. Our findings revealed that structurally similar triterpenes such as α-amyrin, β-amyrin, and β-sitosterol had strong binding affinities towards the DNA-directed RNA polymerase and can inhibit this pivotal viral enzyme. The stability of one of the drug candidate molecules, α-amyrin with the strongest binding affinity towards the binding cavity of the enzyme was also confirmed via molecular dynamics simulation. This study showed that α-amyrin is a promising DNA-directed RNA polymerase inhibitor to treat monkeypox disease. It also paves the way for the idea of the potential dietary supplement candidate for monkeypox patients.

BACKGROUND: There is a trend of increasing incidence and mortality from prostate cancer. Existing methods for early diagnosis and screening of prostate cancer did not demonstrate enough efficiency.
AIM: To improve the quality and efficiency of diagnostic measures for prostate cancer through a personalized approach to patients based on an analysis of a set of risk factors.
MATERIALS AND METHODS: The methodology was developed using the data from the population-based Cancer Registry of the Altai Territory, created at the Altai Regional Oncology Center in Barnaul, Russia. At the moment the Cancer Registry included information on 308 550 patients with malignant neoplasms, including 15 167 males with prostate cancer. On the basis of the method of prostate cancer risk assessment proposed by Lazarev AF an automated program for early diagnosis of prostate cancer has been developed. Testing of this technique included assessment of 532 patients (aged between 23 and 82).
RESULTS: 128 patients were determined to belong to the high risk pre-cancer group. A high-risk precancer registry was created, which included the patients having individual risk of developing prostate cancer either increased or high or absolute. Upon a set of in-depth examinations, 7 of 128 patients (9.3%) were diagnosed with prostate cancer, all at early stages (I or II). Thus, the incidence of prostate cancer among the patients from the high risk pre-cancer registry was significantly higher than the average observed during prophylactic examinations (0.01%).
CONCLUSION: The automated program for early diagnosis of prostate cancer could be implemented with the aim to assign in-depth examination in more targeted manner to patients at high risk of prostate cancer and to contribute to detection the cancer in the early stages.
Occupational Burnout among Special Educators
Authors: Strzelecki Dominik , Nieradka Filip
Published: March 2024

Occupational burnout is a phenomenon manifested through depersonalisation, emotional exhaustion and reduced job satisfaction. This syndrome is primarily associated with helping professions, which include the work of a special educator. Experiencing symptoms of burnout by special educators may reduce not only their quality of life, but also the effectiveness of their interventions with clients. Starting from the presentation of Maslach’s concept of occupational burnout, an attempt was made to briefly characterise the specificity of the special educator’s work and to indicate potential sources of the burnout syndrome, moving on to the presentation of selected sociodemographic variables that may differentiate its level. The aim of the research was an attempt to determine the level of occupational burnout and to check whether selected demographic and social factors, such as age, type of institution and its location, differentiate the level of occupational burnout of special educators. The research used a diagnostic survey method with the use of a questionnaire technique. The results showed that special educators do not experience strong occupational burnout and demonstrate relatively high personal commitment. The analyses also showed that the age of special educators differentiates two components of professional burnout: depersonalisation and personal commitment.
Perfectionism and Self-Acceptance vs. Quality of Interpersonal Relationships

People with increased perfectionism have greater interpersonal difficulties. It can also be concluded that low self-acceptance may be associated with difficulties in relationships with others. The aim of the study was to investigate how self-acceptance explains closeness in interpersonal relationships and the level of positive relationships with others. It also focused on how closeness in relationships and the quality of relationships with others is explained by self-acceptance and some sub-dimensions of perfectionism. The sample consisted of 219 adults aged 18–64 (M = 32.63; SD = 12.96) who completed the Perfectionism Scale (BTPS), the Psychological Well-Being Scale (PWBS) and the Unidimensional Relationship Closeness Scale (URCS). The statistical methods included correlation and regression analyses. Self-acceptance explains the intensity of positive relationships with others as opposed to closeness in relationships. In terms of perfectionism, positive relationships with others were explained by self-acceptance, self-esteem conditioning and action doubt. The results are a prelude to further research on the relationship between perfectionism, self-acceptance and interpersonal relationships.
Perfectionism and Attachment Styles vs. Types of Entering into Interpersonal Relationships
Authors: Gałązka Wiktoria , Gorczyca Martyna
Published: March 2024

The aim of the study was to answer the question whether different types of entering into interpersonal relationships are explained by different types of perfectionism and by attachment styles. The study included 169 adult people, consisting of 96 women and 73 men. The primary research tool was Wiggins’ Interpersonal Adjective Scales (IAS-R), which is a self-report method and consists of 64 items. Additionally, Plopa’s Attachment Styles Questionnaire was used to study attachment relationships and this tool consists of 24 items, as well as the Big Three Perfectionism Scale (BTSP) by Smith et al. consisting of 45 items, which is currently in the adaptation process to Polish conditions. It was assumed that different types of entering into relationships are explained by different types of perfectionism and attachment styles. The research results have shown that different types of entering into interpersonal relationships are determined by different dimensions of perfectionism. Perfectionism explains 18–30% of the variation in interpersonal relationships. It has also been proven that none of the non-secure attachment styles are associated with less adaptive ways of entering into relationships.
Three Ways to Read Dąbrowski’s Theory. It Is Not All Flat Here. Constructing a Neo-Dąbrowskian Approach
Authors: Chojnowski Dominik
Published: March 2024

This article analyzes Dąbrowski’s theory of positive disintegration referring to current debates in the USA which discussed certain parts of the theory (e.g. overexcitabilities) and neglected others (e.g. dynamisms). This approach caused simplification of the theoretical framework proposed by Dąbrowski and inscribed it into the narrow quantitative understanding of science. Lastly, Piechowski proposed to significantly modify Dąbrowski’s theory and to even discard the two lowest levels of development in theory. This caused a reaction by Tillier and Mendaglio who tried to defend the original concepts of the author of the theory. This article juxtaposed these two interpretations of the theory and shows a third possible interpretation based on English and Polish texts written by Dąbrowski. This interpretation solved problems present in the previously mentioned approaches to the theory and shows the way forward into more systematized theoretical research which is seriously needed if we want to further develop theory and its main notions.
Pedagogical Studies and Preparation for the Teaching Profession. Qualitative Research Report: Perspective of Male Preschool Teachers
Authors: Koperna Paulina
Published: March 2024

Working as a teacher requires obtaining appropriate qualifications and acquiring knowledge and competences during university studies. Although the importance of teacher education quality is emphasized, many problems related to this process are pointed out. The objectives of the qualitative research were to recognize and understand the male preschool teachers’ experiences during pedagogical studies and recognize their assessment of the quality of preparation for the teaching profession from the perspective of time, and thus to answer the questions: How do male preschool teachers perceive and evaluate studying in pedagogy? How do they evaluate their own situation during studies? What are their proposals of changes in teacher education? Research using narrative interviews was conducted in 2019 and 2020 among 18 male preschool teachers from Poland. Based on the analysis and interpretation of the research material, the categories describing male perception and evaluation of pedagogical studies as well as evaluation of male situation during studies and proposals of changes were distinguished. The research results indicate that male teachers severely evaluate pedagogical studies and make demands to improve their quality. The narratives were referred to the social constructivism and the interpretive paradigm. It was indicated that male teachers, by reflecting on the quality of pedagogical studies and proposing solutions, fit into the model of a reflective practitioner.
