Published: December 2024

Introduction: Health policies aimed at improving public health have often focused exclusively on access to basic health services, sometimes at the expense of the quality of care. Assessing care quality in liver transplantation is essential to control and meet healthcare needs. The objective of this study is to examine patient satisfaction regarding care during post-liver transplant hospitalization phase.
Methodology: We conducted a prospective, descriptive, and observational study using a questionnaire to assess satisfaction of liver transplant patients. An individual, anonymous, semi-structured, and self-administered survey was employed, evaluating patient satisfaction across five areas: staff care, hospital organization, inpatient facilities, quality of services provided, and respect for privacy, confidentiality, and care continuity. The survey included affirmative statements with Likert-type responses.
Results: We analyzed 79 responses from 86 transplanted patients (response rate: 91.86%). Just over half of the sample were men (45; 56.96%), with an average age of 48.61 ± 11.61 years (range: 24-69). A total of 81.01% received care quality exceeding their expectations. Moreover, 72.15% reported better health than upon hospital admission, and nearly all participants (98.74%, 78) reported satisfaction with the care received during this period.
Conclusion: Our findings indicate a high level of satisfaction regarding care received post-liver transplantation.

Psychometric Properties of the Spanish Version of the Cannabis Refusal Self-Efficacy Questionnaire (S-CRSEQ) in Young Adults Who Use Cannabis
Authors: Ponce Bella M. González , Carmona José , Lozano Óscar M. , Fernández-Calderón Fermín
Published: December 2024

Cannabis refusal self-efficacy, or the ability to refuse cannabis, is key to understanding cannabis use, its consequences, and cannabis use disorders. Currently, the only instrument available to measure this construct is the Cannabis Refusal Self-Efficacy Questionnaire (CRSEQ), which exists only in its original English version. This study aimed to provide a Spanish version of the CRSEQ and evaluate its psychometric properties. A community sample of cannabis-using young adults (n = 612; Mage = 21.04, SD = 2.16; 38.4% female) was recruited using a targeted sampling procedure. Participants completed the Spanish CRSEQ at baseline and a three-month follow-up (n = 505), along with measures of cannabis use, cannabis-related consequences, and protective behavioral strategies. The study successfully replicated the three-factor structure of the original instrument, although one item was reallocated to a different factor. The Spanish CRSEQ showed adequate internal consistency, temporal invariance, and predictive validity, establishing it as a valuable tool for assessing cannabis refusal self-efficacy among Spanish-speaking young adults.
Delocalized entropy aging theorem
Authors: Aimbetov Rakhan
Published: December 2024

Age-related alteration of intracellular processes has been recognized as tipping of homeostatic balance towards increased entropy, reflected in, for instance, such hallmarks of aging as the loss of epigenetic information and disruption of proteostasis. Although the hallmarks of aging are useful for contextualizing geroscience research, the framework itself does not explain what fundamentally causes them to emerge in the first place. Herein, I propose a theorem that aims to explain the emergence of the hallmarks of aging as phenomena secondary to extracellular matrix chemical crosslinking, suggesting that the ensuant age-related extracellular matrix stiffening is a causative upstream agent in the aging process.

Recommendations emphasize optimizing model architectures, standardizing evaluation metrics, and fostering international collaborations to enhance model generalizability and clinical applicability. Future research opportunities include integrating multimodal data and addressing convergence dynamics in FL algorithms. By tackling these challenges, FL has the potential to revolutionize medical diagnostics, ensuring both innovation and ethical compliance.
Comparative Analysis of Rocket Engine Technologies for Long-Term Space Exploration
Authors: Abbas Aun
Published: December 2024

This paper offers a wide-ranging comparative assessment of several rocket engine technologies envisioned for long-term space exploration. The systems examined include Nuclear Thermal Propulsion (NTP), Chemical Rocket Engines, Ion Thrusters, Nuclear Electric Propulsion (NEP), and Plasma Propulsion Systems. The comparison centers on crucial metrics such as efficiency (specific impulse), thrust, energy requirements, safety, cost considerations, scalability, environmental implications, reliability and upkeep demands, as well as technological maturity. By weighing these propulsion methods against one another, the study aims to pinpoint the most viable candidates for expeditions to Mars, asteroid mining operations, and missions into deep space. Our findings suggest that although NTP achieves a high specific impulse combined with moderate thrust, Ion Thrusters and Plasma Propulsion Systems excel in efficiency for sustained, longer missions. Nevertheless, factors like safety, expense, and maturity of the technology hold significant weight in choosing the optimal propulsion system for future space projects.
A Comprehensive Approach to the Yang-Mills Existence and Mass Gap Problem Using Differential Geometry and Dynamical Systems
Authors: Chen Wen-Xiang
Published: December 2024

The Yang-Mills existence and mass gap problem is a fundamental challenge in mathematical physics, posing significant implications for our understanding of quantum field theories. This paper presents a comprehensive theoretical framework integrating differential geometry and dynamical systems to address this problem. By introducing curvature concepts and Lie derivatives, we explore the topological invariants associated with Yang-Mills fields, particularly focusing on winding numbers and their relation to the mass gap. The approach incorporates various methodologies, including Poincaré/Lorentz covariance, effective field theories with cut-offs, and the calculation of Wilson loops, to establish the existence of a mass gap. Detailed mathematical derivations and the construction of relevant theorems are provided to substantiate the proposed framework.
Computer-Aided Analyses and Optimisation of Fluid-Thermal Systems Using Excel
Authors: El-Awad Mohamed Musadag
Published: December 2024

With its wide availability on personal computers, Excel has been used as a graphical or computational tool in various engineering courses. Numerous papers on the use of Excel as a teaching aid have also been published in relevant journals or presented at specialised conferences over the past two decades. However, most of the previous experiences and efforts, if not all, focus on a particular type of analyses or a particular feature of Excel and do not utilise the full capability of Excel as an effective educational modelling platform. Moreover, the relevant papers are written in the form of short research articles and do not describe a general approach or provide sufficient information for using Excel as a modelling platform for the various types and levels of thermofluid analyses. This book complements the previous efforts in this regard by first describing an Excel-based modelling platform that is adequate for conducting various types of computer-aided thermofluid analyses and then showing how the platform can be used to deal with each type of these analyses.
Behavioral Effects of Acetaminophen During a Scary Experience
Authors: Yerman Savannah , Barclay Pat
Published: December 2024

Acetaminophen (paracetamol) can blunt various emotional states and evaluations, seemingly through the same mechanisms by which it dulls the affective component of physical pain. However, most of this work has used self-report or neural measures, with more limited investigations into behavioral effects of blunting emotions pharmacologically. As emotions influence behavior in ways that are adaptive on average, interfering with them might lead to unwanted behavioral changes. For example, disrupting the affective processing of a scary situation might lead individuals to react to it less cautiously. 260 participants were given either 1000 mg of acetaminophen or placebo capsules prior to a frightening virtual reality plank walk at extreme heights. Compared to the placebo group, those on acetaminophen stepped onto the plank sooner, walked across it faster, and had lower heart rates. These findings suggest that acetaminophen might reduce cautious behaviors in dangerous situations, but could also be potentially useful in clinical settings where overly cautious and avoidant behaviors are disproportionate to the danger posed.
Exploring the Structure of the School Curriculum with Graph Neural Networks
Authors: Garzon Benjamin , Perri Vincenzo , Qarkaxhija Lisi , Scholtes Ingo , Tomasik Martin J.
Published: December 2024

School curricula guide the daily learning activities of millions of students. They embody the understanding of the education experts who designed them of how to organize the knowledge that students should acquire in a way that is optimal for learning. This can be viewed as a learning 'theory' which is, nevertheless, rarely put to the test. Here, we model a data set obtained from a Computer-Based Formative Assessment system used by thousands of students. The student-item response matrix is highly sparse and admits a natural representation as a bipartite graph, in which nodes stand for students or items and an edge between a student and an item represents a response of the student to that item. To predict unobserved edge labels (correct/incorrect responses) we resort to a graph neural network (GNN), a machine learning method for graph-structured data. Nodes and edges are represented as multidimensional embeddings. After fitting the model, the learned item embeddings reflect properties of the curriculum, such as item difficulty and the structure of school subject domains and competences. Simulations show that the GNN is particularly advantageous over a classical model when group patterns are present in the connections between students and items, such that students from a particular group have a higher probability of successfully answering items from a specific set. In sum, important aspects of the structure of the school curriculum are reflected in response patterns from educational assessments and can be partially retrieved by our graph-based neural model.

Published: December 2024

Herbal products, many scientifically unsupported, are a popular means of improving health. Given the uncritical media coverage of herbal remedies that previous research documents, we aimed to develop an effective tool to promote their more critical consumption. We developed an inoculation-based intervention - a random news generator that reveals the persuasive strategies commonly used by the media: appeals to nature, tradition, availability, and pseudoscientific jargon. We tested the effectiveness of the intervention across three preregistered experimental studies. In a classical laboratory setting (N = 243), we demonstrated the effectiveness of active inoculation - a guided use of the random news generator which motivated participants to refute media strategies; the effects persisted ten days after the intervention. Based on these findings, we developed a self-standing online intervention and tested it with a sample of students (N = 439) and a community sample (N = 452). The intervention led to a more critical evaluation of a fictive herbal product, an unrelated alternative practice, as well as reduced intentions to use a broader range of herbs to improve health and general trust in traditional, complementary, and alternative medicine industry. The inoculation was more efficient in reducing trust among participants with an intuitive thinking style who endorse magical health and extra-sensory perception beliefs, thus, among participants whose profile is predictive of greater use of herbal remedies. The developed tool has a range of possible applications within different stakeholder groups.
Infant Geometry
Authors: Dillon Moira Rose
Published: December 2024

Geometry is at the foundation of many of humanity’s greatest cultural achievements, from art and architecture to science and technology. This chapter explores the origins of humans’ unique capacity for geometry by describing the early emerging geometric sensitivities of human infants. Initially, infants show limited sensitivities to the geometry of 2D visual forms, discriminating the relative lengths of a form’s parts but not the angles at which those parts meet, consistent with the hypothesis that infants differentiate forms by their shape skeletons. Nevertheless, infants’ sensitivities to the geometry of 2D visual forms may become increasingly abstract with their acquisition of natural language, paralleling the increased geometric abstraction that underlies toddlers’ developing 3D object recognition and categorization. Such development may ultimately support informal learning of the foundational geometric building blocks of formal geometry, like those found in Euclid’s Elements, with concepts like parallelism, perpendicularity, and angle, and may thus set the stage for formal learning of geometry in school.
Introduction to Evolutionary Period Theory（EPT）
Authors: 姚齐源  , 宋晓丽
Published: December 2024

The world is currently facing a major challenge: is there a terminal model or universal model that all countries can follow generally? Solving this difficult problem requires finding new problem-solving tools, and the Evolution Period Theory(EPT) proposed by the two authors is such an exploration.The Evolutionary Period Theory is a theory that reveals the evolution process of human economy, or two types of dissipation processes (i.e. the self dissipation and the mutual dissipation), based on improving of the theory of dissipative structure by the authors.Both of these processes need to be periodically promoted within the controliing by institutions and openness.At present, the most developed countries in the world have gone through four periods of agriculture, industry, service, and cultural, and are about to enter the network period. In this process of progress, institutions and openness themselves also undergo periodically changes. Therefore, there is no such thing as a universal model, only a universal period.As an application, this article compares and analyzes the Washington Consensus and the Beijing Consensus, reveals their common problem of attaching important that “development is the key principle“, and proposing a new approach that“ progress is the key principle” .

Published: December 2024

This study aims to evaluate the impact of Project-Based Learning (PjBL) assisted by Artificial Intelligence (AI)-based mind mapping on the digital literacy competency of biology education students at Sembilanbelas November University (USN) Kolaka. The sample used in this study was students of the 2021 batch of USN Kolaka. This study used a one-group pretest-posttest design. The research instrument was a digital literacy questionnaire compiled based on information, communication, content-creation, social-emotional, and problem-solving indicators. Data analysis was descriptive (average) and inferential (paired sample t-test). The findings indicated that biology education students' average posttest value for digital literacy competency was 77.96 > the average pretest value of 61.06. The significance value of digital literacy competency was 0.000 < the significance value of α of 0.05, so it can be inferred that the implementation of PjBL assisted by AI-based mind mapping can facilitate more innovative and interactive learning and encourage the development of students' digital skills.

Authors: Sara A. Al-Kenany  , Nada N. Al-Shawi
Published: December 2024

Doxorubicin is a wide-range antineoplastic agent; nonetheless, doxorubicin's related cardiotoxic adverse effect that is mediated via oxidative damage restricts clinical use. Dimethyl-Fumarate an agent to manage multiple sclerosis exhibited an anti-oxidant, and anti-inflammatory activity by stimulating Nrf-2-pathway. The current investigation was developed to examine how likely DMF protect against Dox-related cardiac injury in rats. Males and females Wistar rats treated by DMF-only (15 mg/kg /day)for 14 days orally or before DOX IP-inj. at (15mg\kg – single-dose on day 14) to prompt cardiac injury. Results revealed that DMF considerably alleviated DOX-related cardiotoxicity, by decreasing CK-MB and LDH serum concentrations & ameliorated histological alterations. Also, there was a significant inhibition in cardiac OS thru reducing MDA-level, increasing GSH, SOD, CAT and Gpx-1; upregulated Nrf2 protein and gene level, promoting HO_1 gene plus protein synthesis, reduced Keap1 and NF-kB genes expression; furthermore, DMF reduced TNF-a, IL-1b signiﬁcantly, and suppressed apoptotic cell death.
In conclusion, the current study established that DMF alleviated the cardiac injury stimulated by DOX via modulating apoptotic responses and reaction to oxidants by stimulating Nrf-2; suggesting that DMF might be used as a possible chemotherapeutic-adjuvant to improve anthracyclines-related cardiotoxicity.
THE IMPACT OF EXTERIOR CERAMIC CLADDING AND TRIPLE-GLAZING ON THE ENERGY AND THERMAL ASPECTS OF COLLECTIVE HOUSING IN SKIKDA
Authors: Imed Eddine Khelfa  , Fatma Khelifa
Published: December 2024

The interrelated issues of climate change and energy saving have become increasingly significant in the present era and are likely to remain so in the future. This is largely due to the complex and far-reaching impacts these topics have on our society and the environment. Furthermore, these issues align with the needs of people who seek comfort in the indoor spaces where they live or work. In this study, a climatic, energetical and thermal examinations were carried out on a multi-family housing structure in Skikda, basing on actual historical energy data from 2022 for calibration and validation of energy models, using principally CEA and METEONORM tools. This last-mentioned climate simulation tool was also used to generate future meteorological data for 2060 and 2100. Two scenarios were studied: the addition of a ceramic exterior cladding and the replacement of single-glazed windows with triple-glazed windows. The aim was to examine the impact of climate change across three time periods (2022, 2060 and 2100) and the influence of the two techniques on energy efficiency and interior comfort. The results showed that the ceramic cladding reduced electricity and natural gas consumption by 10% and 34% respectively, by insulating the interior from outside temperature variations. Triple-glazed windows reduced natural gas consumption by 27%, but did not reduce electricity consumption due to increased artificial lighting requirements. Analysis of thermal comfort showed that both two intervention scenarios resulted in enhanced conditions. These results are important for guiding energy renovation decisions for buildings in similar climatic zones.
Integrating Environmental Priority Concerns in Building Planning and Production in Niger Delta, Nigeria
Authors: Ujene Anthony Okwogume
Published: December 2024

This study aims at encouraging and supporting building developers to integrate environmental concerns more centrally in the planning and production management of buildings in Niger Delta, Nigeria. The objectives are to evaluate the integration level of environmental sustainability concerns, the barriers to effective integration of the concerns and design a decision framework for effective integration of the environmental concerns in the production process. A purposive survey of 148 stakeholders with structured questionnaire resulted in 136 valid responses from; Architect (30), Builders(14), Clients(35), Engineers(22), Town Planners(18) and Surveyors (17). Data were analysed using descriptive, mean score, and Kruskal Wallis tests. The study concludes that, the highest level of integration is given to concern for air quality, natural lighting, and landscape & historical sites protection, while only about 50% of the identified concerns attained moderate integration level.
The study found that higher final costs, lack of sustainability promotion strategy, lack of demand and lack of building codes and regulation are the most significant barrier to the integration of environmental concerns, with all the stakeholders having common views on the issues. Based on the findings it is recommended that Government and her agencies should provide the building codes and regulation as well as the enlightenment and supports which will enhance integration of environmental concerns in building planning and production. Stakeholders should endeavour to apply the designed decision framework to enhance the integration of the environmental concerns for sustainable development.
USING COAL FLOTATION WASTE AS A HEAT-INSULATING BILLING FOR THE HEAD PART OF A FORGING INGOT
Authors:   Karaganda State Industrial University, Ibraev I.K.
Published: December 2024

The experience of using coal flotation waste as a weakly exothermic insulating backfill for insulating the head part of forging dead-melted steel ingots is presented. It has been shown that when using weakly exothermic fills based on single-component fills in the form of coal flotation waste, it is possible to reduce the chemical heterogeneity of the ingot by producing a closed shrinkage cavity, which allows halving heat loss and depth of penetration of shrinkage looseness into the body of the ingot, reducing the segregation of impurities, compacting the head part of the ingot and increasing the yield; moreover, the profitable part of the ingot is more dense and less contaminated with nonmetallic inclusions. The studied patterns of the formation of a closed shrinkage cavity with a dense “bridge” in the head part of a dead-melted steel ingot made it possible to develop and implement a technology for casting large forging ingots of sufficiently high quality using weakly exothermic heat-insulating materials based on metallurgical waste (coke screenings, coal flotation waste)
Development of a simulation model of grain delivery in global supply chains
Authors: Khomenko Yurii , Matsiuk Viacheslav , Okorokov Andrii , Gorobchenko Oleksandr
Published: December 2024

The main export shipments of grain to Ukraine are carried out through commercial seaports of the Black Sea, while the complex and multiphase transportation process creates delays and leads to additional costs at the points of connection of various types of transport. The purpose of the study was the process of transporting grain cargo for export through commercial seaports. Ukraine is a developed agricultural country that produces a significant share of the world’s grain volume, most of which is exported. The optimisation simulation model of multimodal grain cargo transportation developed in the study, in contrast to the existing ones, is a multiphase process with many initial parameters, subsystems, and technological elements that adequately reflect all components of the technological process of organising transportation by road, rail, and sea, and helps to optimise these processes. The model consists of several transport and technological subsystems, each of which corresponds to the process of grain transportation by road, rail, or water. The minimum total duration of cargo transportation from the place of origin to the moment of sending grain cargo for export by sea was chosen as the optimal criterion. To establish the minimum required number of replications and the minimum required model time, a series of experiments were performed, where the key and systematic modelling measurement parameter is the total time of grain delivery by land, from the point of origin to the sea trade terminal. As a result of modelling, the optimal number of rolling stock of different types of transport and the transportation time for each phase of the process were determined. Logistics operators of the agro-industrial sector can apply the model to improve grain delivery routes and schemes, evaluate and improve technological parameters, and minimise transportation time and costs
Composition and sources of information and analytical support for agricultural land valuation
Authors: Dorosh Y. , Kuryltsiv R. , Bratinova М. , Myronov О.
Published: December 2024

It is determined that in order to form a model for agricultural land valuation, it is necessary to use modern methods and tools, in particular, remote sensing, machine learning and artificial intelligence, big data analysis, geographic information systems (GIS), and agroscouting. It is established that the composition and sources of information and analytical support for such a model are crucial. We have determined that among the factors affecting the price and value of agricultural land, we should consider such indicators as environmental sustainability, crop yields, infrastructure development, cultivation technologies, production organisation, logistics, etc. The analysis of these factors and the results of the studies conducted indicate the need to use a large amount of data to ensure an accurate valuation of agricultural land. Taking into account these factors and the indicators presented in the study will make the assessment more comprehensive and objective, which, in turn, will facilitate informed decision-making in the field of land relations. It is established that the data available in the state registers do not allow for an objective determination of the value of agricultural land plots. It is also noted that the sources of information for obtaining quantitative and qualitative indicators should ensure their relevance, completeness, reliability and timeliness. The author provides a dynamic list of geoportals that are recommended to be used to obtain such information.

Authors: Sanjo ADEWALE Peter , Konye OYIBO-UBIDO Rebecca
Published: December 2024

The traditional teaching methods employed in primary school Mathematics often overlook the importance of fostering creative thinking, resulting in poor academic performance. This study investigated the impact of Activity-Based Learning (ABL) on Mathematics performance among primary school learners in Eti-Osa Local Government Area of Lagos State, Nigeria. A descriptive survey research design was employed, involving 50 students divided into three groups: traditional method (control), ABL (experimental), and combined method (integrating ABL and traditional methods). Data collection was done using an achievement test administered to students and a questionnaire administered to 50 primary school teachers. Data collected were analyzed using means with percentages, t-tests, and analysis of variance (ANOVA). The results revealed a significant difference in Mathematics performance between the ABL group and the traditional method group, with the ABL group demonstrating improved performance (t-test). However, ANOVA results showed no significant difference between the control group, ABL group, and the combined method group. The study concludes that integrating ABL with traditional methods can positively influence primary school learners’ mathematics performance. Recommendations include incorporating ABL into Mathematics instruction, providing resources and training for teachers, and conducting further research to explore long-term effects and scalability.

Published: December 2024

Increasingly, undergraduates in Nigerian universities are required to undergo compulsory training in entrepreneurship education to develop skills that could lead to job creation, economic growth, and enhance their employability upon graduation. However, despite the significance attached to entrepreneurship education in Nigeria, little is known about the entrepreneurial competencies of Library and Information Science undergraduates in Kwara State. The sample included 412 Library and Information Science undergraduates from three purposively selected universities in Kwara State. The findings revealed that the respondents were aware of various entrepreneurial opportunities within the Library and Information Science discipline. Some identified entrepreneurial competencies of the respondents included initiative, creativity and innovation, integrity, and communication and networking skills, among others. The study recommends that university management should improve the infrastructural facilities available for entrepreneurship education in their respective institutions to enhance the training and practical experience that undergraduates receive. Additionally, university management needs to increase funding for entrepreneurship education. This improvement would significantly encourage and boost undergraduates’ participation in the programme.

Authors: Rahmadani Rahmadani , Supriningrum Risa , Sa'adah Hayatus
Published: December 2024

The solvent type plays a crucial role in influencing the extraction of active compounds from natural materials. The peel of kapul fruit (Baccaurea macrocarpa) is known to contain flavonoid compounds with notable antibacterial properties. This study aimed to quantify the total flavonoid content in kapul fruit peel extract by evaluating the effects of different solvent types using the UV-Vis spectrophotometric method. The analysis revealed the presence of secondary metabolites, including alkaloids, saponins, and flavonoids. The total flavonoid content of the kapul fruit peel extract varied significantly across different solvents: 4.7238 ± 0.5807 mgQE/g for ethanol, 2.9699 ± 0.1539 mgQE/g for ethyl acetate, and 2.0417 ± 0.4236 mgQE/g for n-hexane. Statistical analysis demonstrated a significant difference in flavonoid content among the three solvent extracts. These results highlight the importance of solvent selection in maximizing the extraction efficiency of flavonoids from kapul fruit peel, which may have implications for its potential therapeutic applications.

ФОНОВІ АНТРОПОГЕННІ ЛАНДШАФТИ ГЕОЕКОТОНУ ПЕРЕДГІР’Я КРИМСЬКИХ ГІР
Authors: Ситник Олексій Іванович
Published: December 2024

Передгір’я Кримських гір розглянуто як своєрідний ландшафтний екотон, якому ландшафтознавці приділяють мало уваги. Ландшафтний екотон передгір’я Кримських гір представлений передгірним лісостепом, що охоплює зовнішні і внутрішні куестові пасма. Тут різноманіття ландшафтної структури та відповідність лісостеповому висотному поясу Кримських гір ускладнюють чіткий поділ екотону на три складових: дві – пристепову і пригірську зовнішні та центральну – контактну. Детальніші дослідження ландшафтного екотону передгір’я Кримських гір  у майбутньому дадуть можливість це зробити. Активне, особливо упродовж двох минулих століть, господарське освоєння передгірного ладшафтного екотону призвело до формування фонових сільськогосподарських польових, садово-плантаційних та лучно-пасовищних фонових антропогенних ландшафтів у межах передгір’я Кримських гір.
ОБҐРУНТУВАННЯ МЕТОДИКИ ОЦІНЮВАННЯ РЕЛЬЄФУ В КОНТЕКСТІ ПРОСТОРОВОГО ПЛАНУВАННЯ ТЕРИТОРІЇ З МЕТОЮ ЇЇ ГОСПОДАРСЬКОГО ВИКОРИСТАННЯ
Authors: Байдіков Іван Анатолійович
Published: December 2024

У статті запропоновано варіант методики оцінювання придатності рельєфу для господарського використання території у процесі її просторового планування. Акцентовано увагу на визначенні і врахуванні властивостей рельєфу та геоморфологічних процесів з метою встановлення їх впливу на господарське використання території (будівництво, сільське господарство). Оцінку рельєфу пропонується здійснювати на основі бальної шкали (таб.4). Представлено алгоритм оцінювання рельєфу території. Основні етапи виконання алгоритму корелюють з етапами представленої методики оцінювання рельєфу: 1. Збір вихідних даних щодо рельєфу території. 2. Визначення геоморфологічних процесів та чинників і встановлення ступеня їх впливу. 3. Оцінювання рельєфу в контексті властивостей геоморфологічних процесів. 4. Обґрунтування придатності рельєфу для господарської діяльності. 5. Укладання результуючої карти рельєфу території.
ІНЖЕНЕРНЕ ЛАНДШАФТОЗНАВСТВО У РОЗБУДОВІ ЛАНДШАФТНО-ТЕХНІЧНИХ СИСТЕМ ПРИЧОРНОМОРСЬКОГО РЕГІОНУ УКРАЇНИ
Authors: Добровольська Вікторія Анатоліївна , Стефанков Леонід Леонідович

Мета – обґрунтувати значення інженерного ландшафтознавства у формуванні сучасних ландшафтно і екологічно збалансованих до прибережних умов Чорного моря ландшафтно-технічних систем. Запропоновано науковцям сучасного інженерного ландшафтознавства, що будуть брати участь у післявоєнній відбудові ландшафтно-технічних систем Причорномор’я, розробці регіональних проектів раціонального природокористування, звернути увагу на: ідентифікацію стадій розвитку прибережних ландшафтно-технічних систем; аналіз їх розвитку у просторово часових аспектах; пізнання сумісної динаміки прибережних ландшафтно-технічних систем з прилеглими наземними і водними ландшафтними комплексами. Дослідження, парагенетичних і парадинамічних взаємозв’язків особливо необхідне для запобігання екологічної дестабілізації ландшафтно-технічних систем, зокрема при їх розташуванні у лиманно-гирлових ландшафтах з їх часто унікальними природними умовами і ресурсами.
