EXPERIMENTAL STUDY ON FLASH BOILING SPRAY OF HIGH-PRESSURE LIQUID AMMONIA JET WITH ROUND AND ELLIPTICAL HOLE NOZZLES
Authors: Li Chen , He Zhixia , Yang Yizhou , Chen Jiafeng , Zhong Wenjun
Published: March 2024

Ammonia is an ideal alternative fuel for mitigating carbon emissions. High-pressure direct injection of liquid ammonia (LNH3) offers significant advantages in enhancing energy efficiency and minimizing emissions. Due to the high saturation vapor pressure, the injection of LNH3 is susceptible to flash boiling. In this study, we used high-speed micro-imaging technology with backlight lighting to establish a high-pressure common-rail LNH3 jet experimental platform and investigate the flash boiling spray characteristics of nozzles with round and elliptical holes. The results demonstrated that under non-flash boiling conditions, the residual LNH3 in the sac chamber and nozzle can rapidly corrode the acrylic material of the nozzle, leading to deformation and failure of the nozzle structure. Under flash
boiling conditions, LNH3 ejected from the hole will produce spherical macroscopic spray morphology. Then, the spray gradually transitions from an elliptical profile to a conical profile as the back pressure increases. Compared to nozzles with round holes, nozzles with elliptical holes exhibit higher flow velocity, which enhances oil-gas mixing and promotes more pronounced flash boiling phenomena. Flash boiling occurs at an earlier stage with an increase in the spray cone angle, thereby improving the atomization characteristics under both flash and non-flash boiling conditions. The tail jet of nozzles with elliptical holes terminates earlier while exhibiting a higher decrease rate in the average gray value, which improves the atomization quality in the tail spray stage and meets the requirements of timing, quantification, and precise control of the fuel injection system.

Authors: Hammouda Sihem , Naji Hassane , Dhahri Hacen
Published: March 2024

In this study, a numerical investigation of a magneto-hydrodynamic (MHD) and backward-facing nanofluidic flow was performed using the thermal lattice Boltzmann method (LBM) with multiple distribution functions to handle dynamic and thermal fields, including the magnetic force. The Cu-H2O based nanofluid is considered as the working fluid, and the Brinkman-Forchheimer model is adopted to mathematically formulate the porous medium. In addition, heat transfer, pumping power, thermal performance index, and entropy generation within a backward-facing step open-ended channel with adiabatic walls has been investigated. A preliminary comparison of the simulation outcome with available numerical results shows that the in-house built code aptly describes the nanofluid flow behavior and heat transfer process. Afterward, a parametric examination of the impact of Hartmann number (0.0 ≤ Ha ≤ 25), Darcy number (10-3 ≤ Da ≤ 1.0), Eckert number (0 ≤ Ec ≤ 10), nanoparticles volume fraction (0% ≤ φ ≤ 4%), and magnetic field tilt (0 ≤ γ ≤ π/2) on streamlines, isotherms, friction factor (Cf), pressure drop, pumping power, average Nusselt number (Nuav), thermal performance index (PI), and average entropy generation ratio (S*) has been conducted. Based on the findings obtained, it can be stated that increases in the nanoparticles' volume fraction and Ha rise Nuav, pressure drop (ΔP), and pumping power (Ppump) occur. On the other hand, PI and S* drop when φ and Ha rise. Bejan's number has also been shown to increase with Ha. It also turned out that increasing the magnetic field tilt involves a rise in heat transfer, pressure drop, and pumping power, except for PI and entropy generation.

Authors: Vidyashree C. S. , Malammanavar S. G.
Published: March 2024

The aim of the current research was to ascertain how the periphytic algae's species composition and diversity varied seasonally and how those changes related to the physico-chemical elements of two submerged macrophytes (Ceratophyllum demersum, Vallisneria spiralis) in the ponds of Kavaledurga Fort. Periphytic algal communities were highly diversified totalling 70 species, and limnological variables were measured in pond water samples over the three seasons of the study period from September 2020 to May 2021. Members of Zygnematophyceae (n = 57) were found in water bodies with a high diversity and covering of macrophytes. Ceratophyllum demersum (n = 64) was an algae rich macrophyte when compared to V. spiralis (n = 25). The main determining factors for this community variability were elevations in temperature, pH, DO, electrical conductivity and nutrients. The species richness and evenness of periphytic algae over the macrophytes were disclosed by diversity indices. From the similarity index, the results indicated a slight difference in populations of periphytic micro-algae between the studied ponds.
Effect of Tetranychus urticae and Polyphagotarsonemus latus (Acari: Tetranychidae, Tarsonemidae) at different infestation levels and feeding durations on chlorophyll content of bean plants
Authors: Akyazı Rana , Soysal Mete
Published: March 2024

The study investigated the effects of different initial infestation levels and feeding durations of Tetranychus urticae and Polyphagotarsonemus latus (Acari: Tetranychidae, Tarsonemidae) on the chlorophyll content of the pinto bean plants [Phaseolus vulgaris L. (Fabaceae)]. The experiment was carried out on 3 cm diameter leaf discs and potted plants. To determine the effects of mite feeding on the chlorophyll content of leaf disc, 0 (control), 5, 10, 15, 20, and 25 mated adult females (24-48 hours old) were separately placed on each disc. Chlorophyll measurements were made 5 and 10 days after the initial infestation. For the potted plant bioassay, young plants were infested separately with different densities of P. latus or T. urticae (5, 10, 15, 20, and 25 females per plant) while noninfested plants acted as the control. Data were obtained at intervals of 5 days for a total of 5 times. The chlorophyll contents at infestation levels of 15, 20, and 25 T. urticae per disc were statistically lower than the control discs after exposure for 5 days. The heavily infested discs with 10 or more T. urticae were destroyed until the second measurement. On the other hand, there was no significant difference between the chlorophyll contents of P. latus-infested and noninfested discs 5 days after infestation. However, the content was significantly lower in infested discs at all infestation levels than in noninfested discs 10 days after infestation. According to the potted plant experiment, the chlorophyll contents of T. urticae and P. latus-infested plants were significantly lower than the noninfested plants at all infestation levels from the 10th and 20th days of the infestation, respectively. A highly significant negative correlation was recorded between chlorophyll content and mite density, as well as exposure time indicating that the leaf chlorophyll content of infested bean plants decreased with increasing mite density and time. It was also determined that P. latus required a longer feeding time than T. urticae to affect the chlorophyll content of the bean plants.
Introducing agents by binding indices: Implications for subjectless presuppositions and agent entailments.
Authors: Smith Ryan Walter , Yu Jianrong , Yu Jianrong
Published: March 2024

(Bale 2007) argues, on the basis of the differential availability of subjectless repetitive presuppositions with again with certain verb classes, that the agent argument of eventive transitive verbs is introduced VP-externally (Kratzer 1996), but that the agent argument of intranstive and stative transitive verbs must be taken as a true argument by the verb. We challenge Bale’s claim from two directions. First, we observe that two classes of eventive transitive verbs, resist subjectless presuppositions with again. Second, we show that the unavailability of subjectless presuppositions with these and other verb classes is not an ironclad argument against severing agents from their verbs generally, and, develop a semantic analysis, inspired by an analysis of stative transitive verbs due to Hale & Keyser (2002), on which the relevant classes of verbs inherently make reference to the agent of their event argument in the form of an anaphoric index. This index is subsequently bound by a functional head that introduces the agent argument. The facts and analysis proposed here have wider theoretical implications for the way agents qua external arguments are introduced in general, suggesting that verbs of certain classes and VP-external functional heads may both play crucial roles in the syntactic introduction of the agent argument and its interaction with sublexical modifiers like again.
Might a Sense of Place Approach Help the Public Connect to Brayford Pool’s Medieval Heritage?
Authors: Hunt Abigail
Published: March 2024

It is challenging for people to perceive a particular aspect of an area’s rich history when it is not obvious, prominent, or interpreted (Hunt, 2021). This article draws on and develops this assertion by establishing the importance of the Brayford Pool in the Medieval Period (1066–1540) and explores the challenges people face when perceiving the influence of this time period within the current landscape. The article uses the perception aspect of Sense of Place as a framework to suggest that these challenges may be overcome through shared authority and public curation. The article argues that this approach could help to re-establish the importance of the area during the medieval period. The article then considers how the principal of shared authority might be applied to create a public history project on the medieval history of the area, owned by the different communities who live, work, study, and engage in leisure activities on and around Brayford Pool. Finally, it considers the way in which this might impact positively on the other aspects of a Sense of Place: how people value a place, how people describe and interact with it, and the importance of its sustainability.
Pandemic Life-lines: A Multimodal Autoethnography of COVID-19 Illness, Isolation, and Shared Immunities
Authors: Filipe Angela Marques
Published: March 2024

As a crosscutting concept in biology, anthropology, and philosophy, immunity has been a critical ‘site’ of debate on the relations between self and other, organism and environment, risk and responsibility, the corporeal and the political. In this Research Article, I trace how these relations and everyday life during the COVID-19 pandemic relied on a web of coordinated—and sometimes unexpected—lines of communication, restriction, and solidarity. Using an experimental approach that combines multimodal autoethnography and multiscalar relational analysis, I present a first-person account of travelling during, testing for, and falling ill and isolating with COVID-19 in late 2021. I explore how pandemic life-lines, including public health measures, vaccinations, devices, and helplines, as well as mundane gestures of care and ecologies of support, acted together as shared immunities. In this exploration, I propose to reconceptualise ‘immunity’ as a process network rather than a defence apparatus, shedding light on how these life-lines may influence differential trajectories of disease and healing. To conclude, I discuss how my conceptual and methodological approach contributes to a social ecological understanding of immunity, that goes beyond the biopolitical, in times of pandemic and in the future.

Generation of a substance with negative mass
Authors: BG Golovkin
Published: March 2024

An analysis of known experiments was carried out to determine the dependence of the mass of electrons on their speed. Errors were discovered in determining the sign of the electron mass. It is shown that at electron velocities above the critical ω = 235696.8871 km/s their masses are negative. The results obtained are explained on the basis of the Principle of Nonequivalence of inertial and gravitational masses since inertial mass can only be positive, and gravitational mass can only be positive or negative The purpose of this work is to show that since radioactive substances can emit electrons with negative mass at velocities above ω, they can be a source of their production.

Published: March 2024

Toluene exposure has been associated with detrimental effects on the central nervous system. Discovering natural products that can offer neuroprotection following toluene exposure is an essential alternative. Nigella sativa (NS), a popular natural supplement, is a good candidate due to its antioxidant and neuroprotective properties. The study aimed to investigate the protective potentials of NS against toluene, on recognition memory performance in the Novel Object Recognition (NOR) test and cellular morphometric measurements of hippocampal CA1 pyramidal neurons. Adult male ICR mice (n=30) were randomly divided into five groups: Group 1 (G1) - corn oil (CO), G2 – Toluene (TOL), G3 - Toluene and NS seed suspension (TOL-NSS), G4 - Toluene and NS oil (TOL-NSO), G5 - Toluene and thymoquinone (TOL-TQ). NS supplementations were administered orally once daily for 14 consecutive days while 500 mg/kg b.w. toluene was administered intraperitoneally from day 8 until day 14. Behavioural NOR test was conducted. Subsequently, mice were intracardially perfused and harvested brains were histologically processed. The somatic size and shape of hippocampal CA1 pyramidal neurons were quantified according to specific morphometric parameters. Toluene reduced recognition memory performance of mice and somatic size of hippocampal CA1 pyramidal neurons. Contradictorily, TQ, NSO, and NSS improved mice recognition memory and somatic size of hippocampal CA1 pyramidal neurons. Somatic shape of hippocampal CA1 pyramidal was unaffected by the various treatments. Although non-significant differences were observed, the results indicate the tendency for toluene to cause impairment, while NS supplementations to improve mice recognition memory performance and brain hippocampal neuronal structure.

Published: March 2024

Gestational Diabetes Mellitus (GDM) is a common but temporary type of diabetes that develops among 10-20% of all pregnant women. It is a major cause of several pre- and post-pregnancy diseases in both mother and offspring. The main causative is altered pregnancy hormones that lead to deficient glucose metabolism. Complications can be preeclampsia, caesarean sections and cardiovascular diseases. This study was designed to determine the phosphorylated and glycosylated proteins present in GDM and to investigate the role of their post-translational modifications (PTMs) in the pathogenesis of GDM. The study was performed on 30 blood samples from pregnant diabetic women (diseased), 30 pregnant non-diabetic women (control) and 30 women without pregnancy and gestational diabetes (normal). Protein extraction was done from blood plasma, and phosphorylated and glycosylated proteins were determined by Enzyme-Linked Immuno-Sorbent Assay (ELISA) by use of specific antibodies. This study showed that proteins found in GDM are highly phosphorylated and O-glycosylated (p<0.01). Furthermore, a bioinformatic investigation was done, which showed that blood coagulation proteins such as the Fibrinogen alpha chain and lipid metabolism-regulating proteins apolipoprotein E, L1 and C-III showed a high potential for phosphorylation, which suggests that phosphorylation can be used as a therapeutic marker in GDM.

Published: March 2024

With the advent of the internet, social media of Facebook and Twitter, as well as the communication technology of WhatsApp and Telegram, the speed and scope of the rumour dissemination has been expanded. Understanding the characterization of rumour dissemination and how it spreads can help in mitigation measures to avoid the spread of the rumour. Therefore, it is crucial to propose a mathematical model, and in particular this paper is concerned with the epidemic model to understand the dissemination of the rumour in social network. The mechanism of rumour propagation is behaving like infectious diseases spread; hence this research adopted the epidemiological model approach. In this network, the compartment is divided into susceptible, ignorant, propagation and stiflers. The basic influence number, the equilibrium points of rumour-free and the endemic equilibrium state were obtained and discussed. For the local stability, the Next Generation Matrix was used. Numerical simulation is performed to understand the dynamics of the spread of rumour in a population or social networks, its impact in a population, and adjusting mechanisms in curbing the spread of rumour.
Calibrating the Parallax View: Understanding the Critical Moments of the Yugoslav Post-Socialist Turn

Published: March 2024

In this article, we seek to provide a new line of sight referring to specificities of the neoliberal turn in post-socialist societies and corresponding transformations of space. By employing the methodological approach that side-by-side explores two mutually exclusive strategies of analytical and empirical survey, we intend to tackle the question of irreducible antinomies pertinent to architectural research methodologies. Block 23 of the Central Zone of New Belgrade, designed by Branislav Karadžić, Božidar Janković, and Aleksandar Stjepanović (1968), has been widely recognised and aptly studied as one of the highlights of modern urban planning and design, conceived and realised in the period of late socialism in Belgrade (Serbia, former Yugoslavia). Featuring a notion of a “parallax gap,” we presume that the reading of Block 23 through two close yet clearly distinctive perspectives can bring a new scope of knowledge and point to the gap inscribed in the buildings themselves. The first point of view is empirical, centred on the notion of everyday life, and concerns the interpretation and use of space by its inhabitants. The second one is analytical, determined by the work of the architect and architectural theoretician, Branislav Milenković. We start from their point of contact and seek to find a shift in the diverging discursive positions producing a parallax gap. By way of architectural drawing, we explore and theorise new possibilities opened up by the actual buildings: interstitial, intermediary, transitional spaces, and spatial in-betweens. We hope to demonstrate the pursuit of both meticulously planned and dynamically conceived spaces open for the unpredictable was not only a way to respond to specific Yugoslav socio-political realities, but that it fostered the capacity of architecture to accommodate the future population and socio-economic transformations.
The Lifestyles of Space Standards: Concepts and Design Problems
Authors: Arancibia Alvaro
Published: March 2024

Space standards are envisioned as a powerful means to regulate dwelling design, ensuring the quality, functionality, and safety of homes. Their ultimate objective is to guarantee a minimum level of design quality that can accommodate a wide range of domestic activities. While space standards primarily focus on isolated quantitative aspects such as overall size, room dimensions, and occupancy limits, they also make assumptions about activities to be performed by ideal “users” and specific lifestyles to be accommodated within a home. However, these assumptions are being challenged by the increasing demands and diverse activities taking place in the dwelling realm, which call into question the validity of existing space standards. In response to these challenges, this article conducts a critical review of the theoretical basis and various interpretations of space standards, particularly in the context of England. It explores their fundamental concepts and historical approaches, as well as examines specific examples of their application and their correlation with design strategies. By delving into the concepts of “the normal” and “the minimum dwelling,” the article discusses the three main dimensions of space standards: program, user, and size. Consequently, it argues for a more comprehensive understanding of the general application of space standards, which requires incorporating architectural design problems, particularly from the perspective of flexibility. This approach takes into account the evolving needs and diversity of households, as well as the creation of inclusive and adaptable living spaces.

Vaccination activities aim to prevent contagious diseases, deaths, and permanent sequels caused by these diseases. Due to the Covid-19 virus, which has affected the whole world, all people have been directly affected by the negative effects of this virüs. Especially since the elderly population is more affected by this virus, it has become the group most exposed to social isolation. Şanlıurfa is accepted as the lowest province in Turkey in terms of Covid-19 vaccination rate. This study was conducted among 507 elderly people, aged 60 and older who lived in Şanlıurfa, between 01.07.2022 and 30.07.2022. The average of the confidence perception sub-dimension was found as 3.14 and the average of conspiracy theories in the sub-dimension was found as 2.79 on the scale used for the study. 35.1% of the participants stated that they did not trust in Covid-19 vaccine, and 64.9% of them stated that they trust it. 23.9% of elderly people who participated in the study stated that they did not receive any vaccine and 43.6% of them stated that they received 2 doses. To the question, “would you get the covid-19 vaccine again?” only 18.7% of the participants (95) answered yes, and 81.3% of them (412) answered no. Informing elderly individuals and families by healthcare professionals about the dangers of the Covid-19 virus and the reliability of vaccines developed against this virus will increase the vaccination rate.

Published: March 2024

The importance of plastic materials continues to develop more and more every year from past to present. As important as the plastics used in almost every area of life are, it is equally important to keep these materials in the environmental cycle. Since 1970, the use and consumption of plastic has increased almost 10 times. A large share of the use of these plastics occurs in the flexible packaging sector. In the multi-layer films used on flexible packaging in the packaging industry, one of the most important issues of the future is the crisis of raw materials, and the other is recycling and sustainability. In this study, it is aimed to evaluate the low density polyethylene/ poly(ethylene-co-vinyl alcohol)/low polyethylene (LDPE/EVOH/LDPE) structured flexible packaging film waste produced by multilayer blown extrusion method within the same LDPE/EVOH/LDPE flexible packaging film and to examine the mechanical property changes of the material. Sustainable environment and economy, reducing the cost of raw materials, obtaining approximately similar mechanical properties are among the objectives of the study. The wastes released from the LDPE/EVOH/LDPE film were granulated in a single screw extruder. Then, the amount of these waste EVOH granules was 5%, 10%, 20% and 25% by weight in the total film, and their production was carried out with reference to the pure EVOH film in a 7-layer blown film extruder. Samples were taken from the films produced in 50µm thickness in accordance with the standards. Tensile test, tear test, puncture resistance test, sealing force test, shrinkage tests were performed. According to the results of the tests, analyzes on the use of scrap EVOH were concluded.
Deep Learning Approaches for Sunflower Disease Classification: A Study of Convolutional Neural Networks with Squeeze and Excitation Attention Blocks
Authors: Ünal Yavuz , Dudak Muhammet Nuri
Published: March 2024

Diseases in agricultural plants are one of the most important problems of agricultural production. These diseases cause decreases in production and this poses a serious problem for food safety. One of the agricultural products is sunflower. Helianthus annuus, generally known as sunflower, is an agricultural plant with high economic value grown due to its drought-resistant and oil seeds. In this study, it is aimed to classify the diseases seen in sunflower leaves and flowers by applying deep learning models. First of all, it was classified with ResNet101 and ResNext101, which are pre-trained CNN models, and then it was classified by adding squeeze and excitation blocks to these networks and the results were compared. In the study, a data set containing gray mold, downy mildew, and leaf scars diseases affecting the sunflower crop was used. In our study, original Resnet101, SE-Resnet101, ResNext101, and SE-ResNext101 deep-learning models were used to classify sunflower diseases. For the original images, the classification accuracy of 91.48% with Resnet101, 92.55% with SE-Resnet101, 92.55% with ResNext101, and 94.68% with SE-ResNext101 was achieved. The same models were also suitable for augmented images and classification accuracies of Resnet101 99.20%, SE-Resnet101 99.47%, ResNext101 98.94%, and SE-ResNext101 99.84% were achieved. The study revealed a comparative analysis of deep learning models for the classification of some diseases in the Sunflower plant. In the analysis, it was seen that SE blocks increased the classification performance for this dataset. Application of these models to real-world agricultural scenarios holds promise for early disease detection and response and may help reduce potential crop losses.
A Fuzzy Based Intelligent Traffic Light Control (ITLC) Method: An Implementation in Ankara City
Authors: İnağ Tuğçe , Arıkan Murat
Published: March 2024

The escalating global population and increased vehicle usage have worsened traffic congestion in metropolitan areas, a significant urban challenge. Addressing this, adaptive traffic light control methods, especially at intersections, are being developed to improve traffic flow and reduce waiting times. This study significantly contributes to this field by implementing Fuzzy Logic in intelligent traffic light systems, focusing on Ankara's Polatlı Refik Cesur intersection. Using the SUMO simulation platform and Python programming, it analyzed waiting times and queue lengths. The initial phase used queue length for each intersection arm as an input. Fuzzy logic rules then determined the output, prioritizing street or phase order for optimal flow. The study further proposed an Adaptive Neuro-Fuzzy Inference System (ANFIS)-based control plan. ANFIS merges neural network capabilities with fuzzy logic, using waiting time and queue length as inputs to regulate the green light duration. Compared to existing traffic systems, this model showed a substantial improvement. It achieved a 36.5% reduction in waiting times, underlining the efficiency of the Fuzzy Logic-based method. This approach not only enhances traffic management but also contributes significantly to the literature on intelligent traffic light control systems. By addressing key urban traffic issues, the study paves the way for future advancements in traffic management technologies.

Natural gas is an indispensable non-renewable energy source for many countries. It is used in many different areas such as heating and kitchen appliances in homes, and heat treatment and electricity generation in industry. Natural gas is an essential component of the transportation sector, providing a cleaner alternative to traditional fuels in vehicles and fleets. Moreover, natural gas plays a vital role in boosting energy efficiency through the development of combined heat and power systems. These systems produce electricity and useful heat concurrently. As nations move towards more sustainable energy solutions, natural gas has gained prominence as a transitional fuel. This is due to its lower carbon emissions when compared to coal and oil, thus making it an essential component of the global energy framework. In this study, monthly natural gas consumption data of 28 different European countries between 2014 and 2022 are used. Symbolic Aggregate Approximation method is used to analyse the data. Analyses are made with different numbers of segments and numbers of alphabet sizes, and alphabet vectors of each country are created. These letter vectors are used in hierarchical clustering and dendrogram graphs are created. Furthermore, the elbow method is used to determine the appropriate number of clusters. Clusters of countries are created according to the determined number of clusters. In addition, it is interpreted according to the consumption trends of the countries in the determined clusters.

Authors: Virolainen Pavel A. , Chekunova Elena M.
Published: March 2024

Microalgae are a rich source of biologically active substances of natural origin, which have potential for use in pharmaceutical, agricultural, food and industrial production. Genetic engineering of microalgae opens up great prospects for creating improved strains that produce various food additives, commercial enzymes, as well as proteins for therapeutic purposes — antibodies, hormones and vaccines. Chlamydomonas reinhardtii P.A. Dang. is a unicellular green alga, a reference organism for studying the genetics of photosynthesis and developing new genetic engineering approaches in microalgae. The advantages of C. reinhardtii include the ability to transform all three of its genomes (nuclear, mitochondrial and chloroplast), low cost and ease of cultivation, safety for humans and the presence of a system for post-translational modification of proteins, which makes this organism a potential platform for use in biotechnology. Over the past few years, significant advances have been made in transgenesis of C. reinhardtii, including the use of new techniques based on the CRISPR/Cas9 genome editing technology. In this review, we summarize the available information on current approaches to transgenesis of the unicellular green alga C. reinhardtii: 1) general principles of transgenic constructs design for transformation of the nuclear and chloroplast genome, 2) popular selection markers used, 3) methods of cell transformation, 4) methods of genome editing using the CRISPR/Cas9 system.

The article presents the importance of the family and its support from the perspective of a person diagnosed with a mental disorder. The given fragment of findings comes from a study whose primary subject was the socio-biographical experiences of people with a mental disorder who benefited from various forms of institutional support. The article focuses on the impact of an institution such as the family, in particular on the importance of its support for people experiencing a mental disorder. The study was conducted in an interpretative paradigm using qualitative methods – an autobiographical narrative interview. A total of 60 narratives were collected with narrators of both genders between 2019 and 2023; the youngest interviewee was 19 years old and the oldest was 65. The analysis of the material allowed us to generate the basic types of families and the type of support present in them.
School Health Education in the Face of 21st-Century Challenges
Authors: Dworak Alina
Published: March 2024

The post-transformation generation of 21st century is living in a world of rapid social, economic, cultural changes, the dynamics of which have an impact on their development and health. Rapid and accelerating transformation of everyday life extends to all institutions of social life, including the school. The consequences of the ongoing transformations are difficulties in adapting the young generation to the constantly changing, unstable reality. The changes taking place in every area of life indicate the need for educational and upbringing activities as part of the socialisation process of the young generation. The school, as an educational environment, is the place where both cultural and health-related patterns of behaviour are developed and perpetuated, with health promotion and health education being the overarching goal. This century has initiated “new” educational thinking, the aim of which is to change individual behaviour and social action. Achieving well-being in all areas of society requires conscious action to increase health potential and its perception – in the declarative and practical dimensions – as a priority value. The challenge for today’s education system is to develop the ability to make health-promoting choices. This is a task for health education, which should become an important task for the school and the teacher being at the centre of school health education.
The Concept of “Child Welfare”: A Review of Selected Theories
Authors: Pisarska Agnieszka
Published: March 2024

The concept of “child welfare” is a legal term, yet due to its nature and significance in the practices of judicial authorities, it falls within the sphere of interest for representatives of other academic disciplines as well, including psychology, pedagogy, and sociology. The legislation does not provide a definition of “child welfare”, which is a deliberate choice by legislators, emphasizing thereby the flexibility in shaping the legal situation of a child. However, this may pose practical challenges for courts of justice and psychologists collaborating with them in court proceedings. In the absence of a legal definition, there is a risk of excessive subjectivity in assessing the welfare of a child in a given factual situation. Hence, there is a need for specification by creating a definition or criteria for child welfare. This article undertakes a literature review to explore theoretical models and studies that explain the understanding of the aforementioned concept. The presentation of an answer to the question of what constitutes a child’s welfare and what serves their best interest began with an elaboration of three discourses about the concern of a child. Subsequently, selected models explaining child welfare are presented from a psychological perspective, accompanied by a description of the criteria based on the literature and law regulations. Drawing upon empirical studies cited in the final part of the article, a description and an explanation of the concept of “child welfare” were constructed within the broader context of related disciplines in the field of psychology and social sciences – namely, pedagogy and sociology.
Critical Disposition Towards the Uncertainty of Events – Aspirations, Endeavour and Plans of Future Teachers
Authors: Czaja-Chudyba Iwona , Kowalska Monika
Published: March 2024

Functioning in a situation of change and uncertainty has become an important determinant of contemporary teachers’ condition. The article assumes the essential role of critical dispositions (especially the so-called critical orientation): courage, reflectiveness, rationality, reality, scepticism, progressive engagement, intellectual submissiveness, principle, independence, flexibility and tolerance for ambiguity, mindfulness and openness, and curiosity as mediators in the purchase of critical rationality, as well as in coping with non-obviousness of events. The qualitative analysis of essays’ content for 66 future teachers of preschool and early school education was concentrated on decoding their aspirations and plans within the process of creating the status change and on revealing by narrators their critical dispositions. Adopting a qualitative text analysis strategy allowed for capturing an in-depth, contextual view of the examined problem. Analysis of the content and form of written statements indicate significant negligence of this development area for students, which may be a derivative of macro-social, educational and personal barriers. Within the light of elaborated research material, it seems to be a matter of great importance to promote the value of critical dispositions as well as to create and apply programmes developing them during the process of preparing future teachers for their professional careers in the situation of cultural and technological changes.

Perfectionism is understood as a personality trait manifested by excessive striving for perfection, high standards and personal criticism. Criticism may concern self-evaluation, behavior, but also one’s body image. The purpose of the study was to investigate how perfectionism is associated with body perception. A question was posed to verify which dimensions of perfectionism have the greatest potential to explain the assessment of representatives of both genders. A total of 213 people were tested, including 108 women (M = 21.76; SD = 2.35). The study used the Big Three Perfectionism Scale (BTPS) and Body Esteem Scale (SOC-BES), of which the former was used to research 10 dimensions of perfectionism, and the latter to analyze three dimensions of self-image for women and three dimensions for men. The results of the regression analysis showed that some dimensions of perfectionism significantly explain individual dimensions of body image for both genders. For women, the following were significant: Self-oriented perfectionism, Self-criticism, Doubts about actions, and Hypercriticism. For men, the following were significant: Self-oriented perfectionism, Concern over mistakes, and Doubts about actions. All regression models explained 17% to 28% of the variance in body image assessment, indicating their associations with perfectionism dimensions.
