HDPE/Fe3O4 composites with Fe3O4 nanofiller content ω = 1, 3 and 5 vol. %. The structure and thermophysical properties of HDPE/Fe3O4 nanocomposites were studied and it was found that with an increase in the concentration of Fe3O4 nanoparticles in the polymer matrix, cardinal morphological changes occur in the supramolecular structure of the HDPE matrix. It has been established that with an increase in the concentration of the nanofiller, the mobility of the macromolecular chains of the matrix and the thickness of the crystalline lamellae decrease. Nanoparticles disrupt the regularity of lamellae in the crystalline phase of the polymer matrix, and in the amorphous region they prevent the formation and growth of new crystalline domains.

Chemical stability of Nd0.33Zr2(PO4)3 fine-grained ceramics, which can be used for immobilization of REE that are part of the HLW was studied. Single-phase Nd0.33Zr2(PO4)3 submicron powders with the structure of the mineral kosnarite were obtained by colloid-chemical synthesis. Powders were obtained by successive annealing at 600, 800, and 900 °C for 6 h at each stage. Ceramics Nd0.33Zr2(PO4)3 has been obtained by Spark Plasma Sintering (SPS) method. The relative density of ceramics was 89.9 %; the average grain size was 5 – 20 μm. The chemical stability of the ceramics in the static mode at 90 °C in distilled water, mineral waters, as well as in acidic media (0.1 M HCl) and alkaline media (0.01 M NaOH) was studied. Ceramics have high hydrolytic stability. The influence of the contact medium on the rate leaching and mechanism of Nd leaching from the surface of Nd0.33Zr2(PO4)3 fine-grained ceramic samples has been studied. The de Groot-van der Sloot model was used to analyze the obtained time dependences of the leaching rate Ri. Nd leaching in acidic medium occurs due to dissociation of Nd from the ceramic surface, in alkaline medium and mineral water due to diffusion from the inner layers, in distilled water due to the dissolution of the ceramic surface layer.

Published: April 2024

Coral reefs are a type of marine organism that has beauty and benefits for other sea creatures’ ecosystems. However, despite its beauty and usefulness, coral reefs are vulnerable to damage such as coral bleaching, which can impact other coral reef ecosystems. This research aims to classify digital images of healthy, bleached, and dead coral reefs. This research method is DenseNet-121 and MobileNet is based on Convolutional Neural Networks. This research uses a dataset from 1582 coral reef image data with three main classes: 720 were bleached, 150 were dead, and 712 were healthy. The testing process is carried out using several forms of split datasets, namely 60:10:30, 50:10:40, and 70:10:20. The test results obtained with a data sharing percentage of 60:10:30 show that MobileNet architecture achieved 88.00% accuracy, and DenseNet-121 achieved 91.57% accuracy. Using a data split percentage of 50:10:40, MobileNet achieved 84.51% accuracy, and DenseNet- 121 achieved 90.52% accuracy. Meanwhile, with a data separation percentage of 70:10:20, MobileNet achieved 85.48% accuracy, and DenseNet-121 achieved 92.74% accuracy.

Constructing Schwartz Values Framework using the Rokeach Values Survey: Human Value Measurement in the Longitudinal Internet Survey for Social Sciences
Authors: Smallenbroek Oscar , Leijen Ingmar , Stanciu Adrian , Van Herk Hester , Bardi Anat
Published: April 2024

This paper proposes a method to measure basic human values using the Rokeach Value Survey (RVS, Rokeach, 1973) within the Longitudinal Internet Studies for Social Sciences (LISS; Scherpenzeel & Das, 2010). The LISS, running for over 12 years in the Netherlands, serves as a valuable source of data to study the development of values across the lifespan. We identify and assign RVS items to Schwartz (1992) value types based on theoretical overlap, and conduct a weak confirmatory multidimensional scaling analysis to assess the coverage of values. The selected items are then used to compute value scales, which are compared to an established value scale (Portrait Values Questionnaire) using rankings and Procrustes analysis. Lastly, the predictive validity of the value measurements is assessed through linear regression, comparing standardized regression coefficients of socio-demographic factors on each value type. By adapting the Rokeach Value Survey to align with the Schwartz (1992) value structure, researchers can establish a consistent framework for assessing human values longitudinally, enabling better comparisons and insights across different studies and time periods.

Published: April 2024

Present day submarine canyons are active conduits for large volumes of sediment, carbon, and pollutants from continents to oceans. However, the evolution of submarine canyons over geological timescales remains poorly understood due to their erosional nature and low preservation potential. The Late Cretaceous Punta Baja Formation represents a well-preserved submarine canyon-fill on a tectonically-active ocean-facing margin. Outcrops provide km-scale continuous strike and dip sections of the 120 m thick and 1.2 km wide feature. An inherited tectonic fabric influenced the location and orientation of canyon incision into fluvial bedrock. The stratigraphic evolution of the Punta Baja submarine canyon is reconstructed from incision to fill, and shows that it remained an active sediment conduit throughout the time period represented by the preserved fill. The depositional architecture of the north-south oriented erosionally confined canyon-fill is asymmetric, with sub-vertically stacked channel-fills to the west, and an overbank confined by the canyon margin in the east. Sedimentary process interactions led to depositional patterns that we consider distinct to submarine canyon fills. Dynamic topography created by mass wasting processes captured sediment and drove knickpoint development, an autogenic mechanism that modifies sediment delivery to the ocean floor. We interpret widespread upstream dipping surfaces in channel-fills as the stratigraphic expression of migrating supercritical-flow bedforms, playing an important role in sediment storage and transport in the canyon. The proximal location of canyons and unique confinement configuration impact transverse and lateral gravity flow filtering, causing depositional patterns in the intra-canyon overbank areas that are less well organised than in published examples of external levees and which were previously poorly characterised for submarine canyons. This study provides insight into how processes that are observed in modern canyons are selectively preserved through the lifetime of the canyon and construct or destroy stratigraphy on geological timescales.
The role of social deprivation and cannabis use in explaining variation in the incidence of psychotic disorders: findings from the EU-GEI study

Published: April 2024

Background and Hypothesis: Recent findings suggest the incidence of first episode psychotic disorders (FEP) varies according to setting-level deprivation and cannabis use, but these factors have not been investigated together. We hypothesized deprivation would be more strongly associated with variation in FEP incidence than prevalence of daily or high-potency cannabis use between settings.Study Design: We used incidence data in people aged 18-64 years from 14 settings of the EU-GEI study. We estimated prevalence of daily and high potency cannabis use in controls as a proxy for usage in the population at-risk; multiple imputation by chained equations and post-stratification weighting handled missing data and control representativeness, respectively. We modeled FEP incidence in random intercepts negative binomial regression models to investigate associations with the prevalence of cannabis use in controls, unemployment and owner-occupancy in each setting, controlling for population density, age, sex, and migrant/ethnic group. Study Results: Lower owner-occupancy was independently associated with increased FEP (adjusted incidence rate ratio (aIRR):0.76, 95% confidence interval (CI):0.61-0.95) and non-affective psychosis incidence (aIRR:0.68; 95%CI:0.55-0.83), after multivariable adjustment. Prevalence of daily cannabis use in controls was associated with incidence of affective psychoses (aIRR:1.53, 95%CI:1.02-2.31). We found no association between FEP incidence and unemployment or high-potency cannabis use prevalence. Sensitivity analyses supported these findings.Conclusions: Lower setting-level owner-occupancy and increased prevalence of daily cannabis use in controls independently contributed to setting-level variance in incidence of different psychotic disorders. Public health interventions that reduce exposure to these harmful environmental factors could lower the population-level burden of psychotic disorders.
This Paper is “Un-reject-able-ish”: Learning and Generalization of Novel Compositional Meanings
Authors: Zheng Xiaochen , Petukhova Anna , Roelofs Jonne , Garvert Mona , Ouden Hanneke den , Cools Roshan
Published: April 2024

The ability to generalize previously learned knowledge to novel situations is fundamental for adaptive behavior. When encountering the novel word “un-reject-able-ish” for the first time, one can swiftly infer its meaning by generalizing from the known elements and integrating them based on abstract structural rules, such as the sequential arrangement of word parts. How do we generate such novel, compositional meaning? To address this question, we developed a behavioral paradigm to quantify structural inference for the creation of word meaning. Participants were taught compositional pseudo-words from an artificial language and subsequently tested with a new set of pseudo-words from the same language. Across three behavioral experiments, we demonstrate that participants can efficiently learn and apply structural rules to infer novel, compositional meanings spontaneously. Moreover, our findings reveal two distinct behavioral patterns during this compositional generalization process. Some individuals employ a rule-based “building” strategy that takes into account sequential order rules, while others adopt a “mixing” strategy that combines individual elements’ meanings but places less emphasis on the structural rules. We further demonstrated that this individual variability in reliance on the rule-based building strategy for meaning composition is partially explained by individual differences in stable trait factors, including general nonverbal intelligence and vocabulary. By investigating the mechanisms of compositional generalization within the realm of language, our research bridges the gap between linguistic compositionality and other domain-general cognitive processes, such as structural inference, visual composition and decision making.

Authors: Pal Rahul
Published: April 2024

This study aimed to identify the association between the Big Five personality traits of the Three Darks. Triad Traits and Empathy. OBJECTIVE OF STUDY 1. To understand the relationship between the Big Five personality traits and empathy. 2. To understand the relationship between the Three Dark triads and their empathy. 3. To understand the relationship between demographic variables and empathy. SIGNIFICANCE: This study is essential for determining the nature of personality and the effects of different demographic variables on empathy in different social contexts. Using different psychological tools, this study highlights the different personalities necessary for healthy and empathetic relationships among human beings. Furthermore, this study attempted to determine how to measure individual differences in empathic processing optimally. This study was designed to establish a relationship between the Big Five personality traits, short dark triads, and empathy among random students from the Indian Subcontinent. I found that agreeableness and openness were the most important predictors of empathy, as measured by the Empathy Quotient (EQ). The results of this study supported the hypothesis that agreeableness, openness, extroversion, conscientiousness, and emotional stability are positively correlated with empathy, the dark triad traits are negatively correlated with empathy, and females are more empathetic than males.

Published: April 2024

Parents’ judgments about their children’s level of interest in different science topics may impact the science-learning opportunities they provide their children. However, little is known about how parents judge these interests. We used the Truth and Bias Model of Judgment (West & Kenny, 2011) to examine factors that may affect parents’ judgments of their children’s science interests, such as the truth (children’s self-reported interest) and potential sources of parental bias. We also investigated whether several individual difference measures moderated the effect of truth or bias on judgments. Children (N = 139, ages 7-11) rated their level of interest in 5 science and 5 non-science topics. Separately, parents (N = 139) judged their child's interest in the same topics. Overall, parents accurately judged their children’s science interests, but we also found evidence of some forms of bias: Parents generally underestimated their children’s science interests. Also, parents’ personal science attitudes were related to judgments of science interests, such that parents more favorable of science tended to rate their children’s interest in science topics higher than parents with a less favorable view. We did not find evidence that individual differences among parents moderated the effect of truth or bias on judgments; however, parents were more accurate at judging the non-science interests of older children than younger children. Parents should be aware that they may be underestimating their children’s interest in science topics and that their personal attitudes about science may be influencing their judgments of their children’s science interests.
Metacognitive monitoring in early elementary school-aged children: Task dependency in monitoring judgements, task consistency in monitoring behaviours.
Authors: Eberhart Janina , Murayama Kou , Sakaki Michiko , Bryce Donna
Published: April 2024

*This is a preprint and not yet published* Metacognitive monitoring is typically considered as a domain general skill that can be applied in different tasks and situations. However, this assumption lacks empirical evidence as few studies tested whether children’s accuracy of monitoring judgments as well as their monitoring behaviours are consistent across tasks. It is also not clear if children who provide more accurate monitoring judgments also show more frequent monitoring behaviours. In the current study 53 elementary school children’s metacognitive monitoring was assessed with four tasks: on the one hand, the accuracy of children’s monitoring judgments was assessed with two computer-based tasks (one task required monitoring of memory and the other task required monitoring of reaction times); on the other hand, the frequency with which they engaged in monitoring behaviours was assessed with two construction tasks. Correlational analysis showed that there was no significant association between children’s monitoring judgment accuracies. In turn, children’s monitoring behaviour on two construction tasks was significantly positively associated. Intercorrelations between children’s monitoring judgment accuracies and monitoring behaviours showed that children who more accurately monitored their reaction time showed significantly more monitoring behaviour when working on construction tasks. Conversely, children’s monitoring judgment accuracy on a memory task was not associated with their monitoring behaviour. These findings suggest that the processes underlying children’s monitoring judgments may be task specific, whereas their tendency to engage in monitoring behaviours may be domain general. Implications for promoting metacognitive monitoring are discussed.
Future and the composition of modal meaning: the view from Igbo
Authors: Mucha Anne , Amaechi Mary , Whibley Fred , Uegaki Wataru
Published: April 2024

In many languages, overt ‘future markers’ play a role in the expression of modal meaning, but their exact semantic contributions vary depending on the particular language and analysis. In some prominent existing accounts, future markers i) contribute prospective time shifting and combine with modal operators or ii) they are part of the functional modal paradigm of a language, on a par with must-type necessity modals. The Igbo future marker "ga" presents an interesting variation on ii). On its own, "ga" expresses necessity relative to a stereotypical conversational background (similar to other future modals). Interestingly, however, "ga" also contributes to the composition of other necessity meanings (≈ MUST) as well as circumstantial possibility (≈ ability CAN). We explore this empirical pattern in more detail, sketch an analysis of the relevant modal constructions involving "ga", and discuss potential theoretical implications from a cross-linguistic perspective.

Together and Apart. Metamorphoses of Images of Taras Shevchenko during the First World War and the Civil War
Authors: Tarasov Konstantin
Published: April 2024

The article delves into the exploration of the formation of the Ukrainian nation within the backdrop of competing ideologies: imperial and socialist. The theoretical framework adopted for this study is Miroslav Hroch’s concept of nation-building phases, which centers around the generational shift from a limited national intelligentsia to a broader educated class, and eventually to a mass movement. Among the myriad factors influencing the propagation of the notion of nationhood, a relatively unexamined one is selected for analysis — the utilization of literature, specifically the works and image of Taras Shevchenko, by various political and public actors. This study draws on sources such as speeches, articles, political symbols, and accounts of visitors to Shevchenko’s grave. During the early 20th century in the Russian Empire, multiple attempts were made to integrate the image of the Ukrainian poet into various discourses. Firstly, he was portrayed as the progenitor of the nation, a supporter of Ukrainian emancipation. Secondly, within the realm of social discourse, Shevchenko was depicted as a political fighter against the monarchical regime. Thirdly, his works were viewed as a component of broader imperial culture. Interestingly, these interpretations could coexist even within the dialogues of political adversaries. The battle for the “appropriation” of Shevchenko’s image came to the fore during the tumultuous period of the First World War and the 1917 Revolution, being transformed into integral elements of the political strife. This symbol was harnessed for political mobilization by advocates of a unified state, proponents of national autonomy, and separatists alike.
An Evaluation of the Curve of Spee in the Maxilla and Mandible of Human Permanent Healthy Dentitions: A Cross Sectional Analytical Study in a Group of Nepalese Population
Authors: Dhital S , Ghimire B , Basnet BB , Shrestha B
Published: April 2024

Introduction: Familiarity with the typical measurements of the maxillary and mandibular curves of Spee can assist clinicians in formulating sagittal plane occlusion and proves beneficial in delivering prosthetic rehabilitation for patients with occlusal derangement. The objective of this study is to evaluate and compare the radius and depth of the Spee curve in the maxillary and mandibular arches among both male and female individuals within young Nepalese population.
Materials and Methods: The study comprised 21 men and 21 women aged between 18 and 30 years. Alginate impressions were made for both the maxillary and mandibular arches and dental stone casts were subsequently created. Digital images of the right side of maxillary and mandibular dental casts were captured using a digital camera and subsequently transferred to a computer. The tips of the distal cusps of molars, premolars, and canines in both the maxillary and mandibular arches were identified. Utilizing the computer software (Corel DRAW), the radius and depth of the Spee curve were measured based on the digital photographs of the dental casts.
Results: The results indicated a substantial difference in the depth of the Spee curve between the mandibular and maxillary arches (p<0.001), with the mandibular arch displaying a significantly greater depth. Furthermore, the Spee curve was notably deeper in females (p=0.045) compared to males. However, there was no statistically significant difference in the depth of the Spee curve in the mandible between genders (p=0.171).
Conclusions: The radius of the Spee curve was unaffected by the gender or arch of the subjects under investigation. Nevertheless, the Spee curve was observed to be significantly flatter in the maxillary arch when contrasted with the mandibular arch. Additionally, a notable difference in the depth of the Spee curve was identified between females and males, with females displaying a greater depth.

Published: April 2024

To accelerate transformations towards just and sustainable future cities across Europe, local and regional projects need to scale up and share sustainability pathways and planning efforts. In this context, Living Labs, and innovation and experimentation spaces in general, have demonstrated great potential in serving as platforms for connecting universities with societal stakeholder, facilitating transdisciplinary collaboration in the innovation process but also as tools for cross-case learning and upscaling innovative solutions. At the same time there is an ever increasing emergence and diversification of these spaces, even within ECIU, that can often create a certain confusion and at the same time reluctance to engage and make use of them or explore their full potential. The ECIU-UTC seed project’s objective was to expand existing research and innovation initiatives of the ECIU by linking established living labs and citizen science projects run by partners and their regional ecosystems. This resulted in an initial Roadmap for the distributed network of a “Living Lab and experimentation and innovation spaces” within ECIU, an effort that will continue in the ULALABS project during the next three years where we will open up the process to the extended ECIU ecosystem. The SMART-ER Conference in Barcelona gave us an initial opportunity to share and reflect the Seed project results together with the broader community but also the objectives and scope of the new project. We envision that the ULALABS project will produce tools, methodologies and experiences that will help the community learn and understand how to make use of these innovative infrastructures to enhance their activity and its impact. At the same time aid with the effort towards the realization of the ECIU 2030 Vision1 by articulating a platform and mechanisms for integrating multi-disciplinary challenge-based research, innovation and learnings; and a distributed network of ECIU physical and virtual collaboration spaces operational and interconnected between the ECIU member universities. In this context, the ECIU consortium in its vision to establish an open, inclusive and collaborative ecosystem should seek to make the existence of the labs visible and promote their active use in teaching, research and innovation activities in future activities.
“Shitty Graphs”: Data Intimacy and the Feeling of Numbers in Type 1 Diabetes
Authors: Rentschler Carrie , Nothwehr Benjamin
Published: April 2024

Diabetes is a self-quantified chronic disease, where measuring blood sugars is the very grounds for understanding and surviving the condition. This article analyzes how people with type 1 diabetes who use continuous glucose monitors (CGMs) share their CGM data visualizations on social media platforms and develop data intimacies with other diabetics around the visual vernaculars of CGM graphs: the “flat line” ideal and the “shitty graph.” CGM graphs mediate relationships between people with type 1 diabetes and how they feel their numbers. Based on a review of posts on r/diabetes_t1 over a period of nine months (August 2022–April 2023), the authors identified and analyzed two recurring visual vernaculars in screenshots of CGM graphs and the talk that occurred around them. As “domains of affective practice,” these subreddit posts and talk around screenshots of CGM graphs mediate the “bad feelings” of diabetes and materialize the charged platform data intimacies between diabetics.
Eco-Activist Social Media Influencers (SMI) on Twitter: Does Credibility Matter?
Authors: Ahmad Mijar Maisarah , Mazinina Aini
Published: April 2024

The emergence of social media specially twitter plays a significant role in today’s era. The bond between people and their smartphones is also inseparable. The first thing that people would do when they wake up is to check their phones. This leads to the deprivation of people watching television. People have now turn to Twitter for any news or trends that are occurring and substitute the physical newspaper. With the vast number of users on social media, Social Media Influencers (SMI) have also been influencing others by their opinions or expertise. However, with all the technologies and changing that are going on, environment still suffers from these man-made developments. Therefore, this paper seeks to understand how the eco-activist SMI create awareness on environment on Twitter. Using Social Credibility Theory, a qualitative content analysis of eco activist SMI twitter accounts was conducted. The findings indicate that trustworthiness, expertise and active online presence are salient features of an eco-activist SMI when communicating environmental messages through twitter.

Published: April 2024

The results of a set of thermal calculations of the air-heating heat exchanger of the dusty waste gases of the thermal disposal of household waste are given. The initial data for the calculations were taken in the practical range when incinerating 1t/h of household waste from the experience of using the specified installations. The heat-recovery unit is designed to heat air for combustion by recovering the heat of the exhaust gases leaving after the turbine of this installation. Its design solution is characterized by the possibility of cleaning work surfaces from deposits of technological dust. The thermal indicators (temperatures of coolants and heat productivity) of the proposed heat-recovery unit under the conditions of its use for waste incineration plants were investigated. Calculations were performed in different modes of operation of the heat-recovery unit during the year, namely: at inlet temperatures of air and exhaust gases in the range from -20 to +20 ºС and from 200 to 300 ºС, respectively, the coefficient of excess air in waste gases from 1.5 to 2, 5 and different levels of dust on the heating surface. The influence of dustiness on the thermal parameters was characterized by the coefficient k, which determined the level of reduction in the thermal efficiency of the heat exchanger as a result of dust deposits on the specified surface and varied in the range from 1 to 0.5. Under the considered conditions was established, that use of the proposed air heater it provides heat output of 72 ÷ 263 kW, cooling of flue gases to a temperature of 107 ÷ 245 °С and heating of air to 96 ÷ 220 °С. At such levels of flue gas cooling, the efficiency of the thermal disposal of household waste increases by 2 ÷ 5%. In the case of a decrease in the heat-recovery capacity of the heat-recovery unit to technologically unacceptable levels, it is necessary to carry out its forced cleaning with compressed air, as provided for in the technical solution of such an air heater.

Consideration of the role of green spaces in urban landscaping is extremely important, as they not only decorate the urban landscape, but also effectively reduce air pollution, regulate the microclimate and play an important role in improving the ecology and quality of life of residents. The purpose of the study was to determine the influence of urban environmental factors on the development and secondary metabolism of plants of the genus Cercis L. Plants growing in Kyiv (Ukraine) under conditions with different air humidity, anthropogenic load, and excess or lack of insolation were selected for the study. Plant growth processes were studied by morphometric parameters of annual shoots of Cercis siliquastrum ‘Alba’ and Cercis canadensis L. growing under different conditions. Morphometric methods, fluorescence microscopy, high-performance thin-layer chromatography and regression analysis were used in the study. The research data show that insufficient sunlight has a negative impact on shoot growth. The specificity of the phenolic profiles that can be used to distinguish between the species Cercis canadensis L. and Cercis siliquastrum ‘Alba’ was established. The principal component analysis confirmed that phenolic profiles depend on habitat conditions and affect plant growth and development. The Gaussian model was used to analyse the growth dynamics of annual shoots during the growing season, which allowed us to describe the specifics of internode formation during the growing season quite accurately. This model allowed us to detect the phenomenon of the last internodes falling off at the end of the growing season, which caused the deviation of the morphometric parameters of metameres from the normal distribution along the time axis. Anatomical studies confirmed that the separation of one or more of the last internodes was due to active corking of the internal tissues of the stem, blocking of the xylem and formation of a separating layer, which led to the fall of the shoot tip. This phenomenon shows signs of plant adaptation to low temperatures in winter. The tops of the shoots often do not have time to lignify and accumulate the required amount of cryoprotectants. With the formation of a separating layer, the available energy resources are redistributed to the lateral buds, which receive the necessary resources to prepare for the winter period and provide new growth in the next growing season. The adaptive potential of the two species of the genus Cercis L. confirms the prospects of their use in urban ecosystems, which can positively affect the conservation of biodiversity in general

One of the key problems that arise in the reproduction of forests in the paradigm of sustainable development of the forest industry is the volume of reforestation, which requires its correlation. This problem requires attention, since effective afforestation and reforestation determine the stability of the ecosystem and the importance of forest resources for the conservation of biodiversity in the forest sector. The purpose of the study is to investigate the features of artificial forest reproduction in the conditions of the forest-steppe climatic and geographical zone. The methodological basis for organising observations included field survey of planting material plots, monitoring the state of crops on the area, conducting analytical substantiation of progressive experience, and evaluating the final results obtained. The study was conducted in the Korsun-Shevchenkivskyi forest enterprise branch of the state enterprise “Forests of Ukraine”. The dynamics of annual volumes of artificial forest reproduction, considering the predominant tree species during 2012-2021, is presented. Additionally, the advantages and disadvantages of transplanting of main and related species in the presented forest conditions were analysed. During this period, there is a fluctuation in the volume of artificial forest reproduction in the forest districts under study. With regard to the transplanting of main and related species, it is worth noting its advantages in ensuring biodiversity and rapid forest regeneration. However, there are disadvantages, such as the possibility of losing genetic diversity and considering local conditions for effective seating. As a result, the study helped to determine the trends and features of forest reproduction in these forest districts, and to note the advantages and disadvantages of transplanting of the main and related breeds in various forest-growing conditions. The enterprise is actively implementing measures for forest reproduction, focusing on intensive planting of forest crops. This is achieved by placing plantations in areas that have been subjected to continuous sanitary and reforestation logging. One of the key tasks of the enterprise is to ensure high productivity of forest crops in the region. For this purpose, significant amounts of reforestation work are carried out, including systematic soil preparation and careful selection of optimal species for specific conditions. Considering the recommendations of forest management, an integrated approach to reforestation is reflected, which ensures sustainable and productive ecosystems in the region. The developed strategies can serve as an important tool for introducing innovations in the field of forestry

The functional load of forests necessitates the activation of meliorative measures to optimize the functioning of agrolandscape complexes. These measures contribute to improving the environmental situation and advancing towards sustainable functioning of forest ecosystems. Therefore, the study of the structural and species formation of forest ecosystems is of significant scientific interest. The aim of the article was to analyse the impact of agroforestry measures on the process of forming the structure of forest ecosystems through a comprehensive examination of interrelationships. The research utilized general scientific methods, including specification, deduction, systemic analysis, synthesis, and abstraction, as well as formalization. During the study, vectors of organizing optimized systems of protective forest plantations were analysed, and environmental protection priorities for the development of agroforestry ecosystems were substantiated. Basic principles of managing the agroforestry complex based on sustainable land use were identified, including a comprehensive approach, ecologization of the process, and continuous monitoring. The study revealed current ecological consequences of irrational melioration for forest plantations, such as increased erosion processes and land resource degradation. Risks and challenges requiring preventive solutions were identified. It was proven that increasing the share of agroforestry plantations would allow optimizing the environmental situation in Ukraine, promoting the regeneration of the natural resource base, restoring landscapes, and minimizing land resource degradation processes. The article proposed key measures to optimize the environmental situation at the local level of forest ecosystems, as well as preventive measures to prevent destructive impacts, including the improvement of legal support and the implementation of strict measures of responsibility for irrational resource use. The value of the conclusions lies in their practical application for monitoring the state and the process of forming the structure of forest ecosystems under the influence of agroforestry measures. They also contribute to the effective development of preventive and regenerative protective measures and the formation of balanced forest ecosystems
