Socio-economic and environmental consequences of the level raise of the Caspian sea in the Caspian sea region of Azerbaijan
Authors:   Azerbaijan Architecture and Construction University, Baku, Azerbaijan, Salimova Vafa Hamlet
Published: February 2025

Among other countries located near the Caspian Sea, the socio-economic life of the Republic of Azerbaijan is more closely connected with the Caspian Sea. The coast of Azerbaijan is the most densely populated territory of the country, 40% of the population lives here. The city of Baku, which is the capital, is also located on the coast, almost the entire industrial complex of the Republic is concentrated here. Land on the Caspian coast is fertile and used in agricultural production. On the coast of the Caspian Sea there are popular resort areas, zones of individual residential development, railways and highways of national and international importance, as well as many sources of communication and communications are laid here. In order to successfully manage agricultural production and increase the area of irrigated land, in addition to increasing subsidies, the study of the region's water resources is also of great importance.
Agrophysical assessment of eroded soils of the south-eastern part of the Lesser Caucasus and ways of their regulation
Authors:   Institute of Soil Science and Agrochemistry of the National Academy of Sciences of Azerbaijan, Baku, Azerbaijan, Suleymanov Alovsat Oruj ogly
Published: February 2025

Increasing soil fertility and crop yield through trimmed application of all agrotechnical, reclamation anti-erosion measures taking into account the agrophysical, chemical properties of soils is a key issue and a decisive factor facing agricultural workers to implement the whole food security program. Therefore, the organization of rational use of land largely depends on the accounting of land areas, their assessment. Based on the studies carried out, the author grouped the soils according to the indicators of bonite balls, which makes it possible to develop differentiated measures to regulate the agrophysical properties of eroded soils. The author compiled a cartogram of the agricultural-industrial grouping of soils on the basis of which the reasons that reduce the fertility of soils and the yield of cultivated crops can be identified, and also developed measures to regulate the agrophysical properties and productivity of soils. Studies have shown that in the southeastern part of the Lesser Caucasus, 64% of the total land area is subject to erosion processes to one degree or another, the main reason for which is the uneven distribution of atmospheric precipitation, the storm pattern of their fall in the spring period, as well as the large spread of the territory, the absence of erosion measures and unfavorable water-physical properties of soils.

Published: February 2025

La fragmentación y segregación urbana son fenómenos complejos que surgen como resultado de procesos de planificación urbana, dinámicas sociales, económicas y políticas. Estos conceptos se relacionan estrechamente, pero tienen características específicas que merecen ser analizadas desde la perspectiva de la planificación de las ciudades. El objetivo de este artículo es analizar las dinámicas de fragmentación y segregación urbana en América Latina, con la finalidad de determinar sus causas, consecuencias y el impacto de las políticas de planificación urbana en estos procesos. A través de una revisión de fuentes académicas y un análisis crítico de casos de estudios relacionados con metropolización y expansión urbana de ciudades representativas de la región, se analizó cómo la estratificación social y las barreras físicas y simbólicas moldean el uso del suelo y perpetúan las desigualdades urbanas. Los resultados de este estudio revelan que la planificación urbana, lejos de ser una solución, intensifica la exclusión social y territorial, consolidando patrones de segregación. Frente a ello, se proponen estrategias orientadas a fomentar la diversidad socioeconómica, garantizar la provisión equitativa de servicios básicos, crear espacios públicos accesibles y promover la movilidad social, con el fin de construir ciudades más inclusivas, sostenibles y equitativas.

Authors: Sadqi Rihab , Tebougou Prosper Nimpa- , Mezzine Samya , Arnould Myriam
Published: February 2025

Introduction: Cat Scratch Disease (CSD), caused by Bartonella henselae, is the most common Bartonella infection in humans, typically presenting as self-limiting regional lymphadenopathy following a cat scratch or bite. Case Presentation: A 10-year-old child developed an atypical form of CSD, characterized by significant elbow swelling and abscess formation. Diagnosis was confirmed through imaging and PCR testing. The case required surgical drainage and antibiotic therapy, highlighting the variability in CSD presentation. Discussion: CSD is primarily transmitted through household cats, with higher incidence in children and seasonal peaks in fall and winter. While most cases resolve without intervention, severe forms may involve systemic or visceral complications. Diagnosis relies on clinical evaluation, serology, and PCR. Imaging techniques such as ultrasound and MRI are essential for identifying atypical presentations. Conclusion: CSD can manifest beyond typical lymphadenopathy, necessitating early recognition and appropriate management. In pediatric patients with suspected hepatosplenic involvement, abdominal ultrasound is recommended. Though often self-limiting, severe cases may require prolonged antibiotic therapy and surgical intervention.

Published: February 2025

The increasing demand for sustainable aquaculture necessitates efficient water quality management to enhance fish health, reduce mortality rates, and improve overall productivity. However, conventional water quality monitoring relies on manual testing, which is labour-intensive, time-consuming, and ineffective in detecting rapid environmental fluctuations. To address these limitations, this study presents EcoGuard, an IoT-enabled smart aquaculture monitoring system that integrates edge computing and federated learning-based predictive analytics for real-time water quality assessment and management. EcoGuard continuously monitors the important water parameters, including pH, dissolved oxygen (DO), temperature, turbidity, and ammonia levels, through a wireless sensor network. The predictive analytics module, employing Random Forest and Long Short-Term Memory (LSTM) models, forecasts water quality trends, enabling early intervention and risk mitigation. A key feature of EcoGuard is its federated learning framework, which facilitates collaborative model training across multiple aquaculture farms while ensuring data privacy and security. The system utilizes the MQTT protocol for low-latency data transmission, while an integrated mobile application provides real-time alerts and decision support for optimized resource management. Experimental validation demonstrates that EcoGuard effectively reduces fish mortality, enhances operational efficiency, and supports sustainable aquaculture practices. By utilizing IoT, AI, and federated learning, the proposed system offers a scalable, cost-effective, and intelligent solution for modernizing aquaculture, contributing to food security, environmental conservation, and resilient fisheries management.

Published: February 2025

Introduction. Granting Ukraine the status of a candidate for membership in the European Union requires the formation of a national agricultural policy in accordance with the principles of the Common Agricultural Policy of the European Union (CAP). One of the priorities of the CAP for 2023-2027 is the promotion of knowledge and innovations, the use of which should ensure the sustainable development of agricultural production and rural areas. Scientific and educational materials for training agricultural advisory service workers should take into account the specifics of the agricultural sector of Ukraine and the requests of Ukrainian consumers of advisory services.
Methods. General scientific research methods, methods of analysis and synthesis, descriptive and analytical method, comparison method and other scientific methods were used to solve the tasks set. The online survey method was used to conduct a study of the activities of agricultural advisory services.
Results. It has been proven that only the system of the National Academy of Agrarian Sciences of Ukraine is capable of ensuring the transfer of innovations in the most demanded areas of advisory services, in particular in the field of economic, legal and financial support – the National Scientific Centre “Institute of Agrarian Economics” and the Institute of Accounting and Finance of the National Academy of Agrarian Sciences of Ukraine, which have already achieved significant results both in improving the qualifications of advisors and in their information, advisory and organizational and methodological support. The introduction of the agricultural knowledge and innovation transfer system (AKIS) in Ukraine, which operates in the EU countries, requires comprehensive support from the National Academy of Agrarian Sciences of Ukraine.
Discussion. The results will be used in further research and the preparation of scientific and educational materials for training agricultural advisors.

Authors: Cordeiro Carlos Felipe dos Santos , Galdi Leonardo Vesco , Echer Fábio Rafael
Published: February 2025

Modern runner-type peanut cultivars have high yield potential, but little is still known about the dynamics of nutrient uptake by these cultivars and whether nutrient uptake differs between maturity groups. This study evaluated the growth, nutrient uptake, and nutrient removal of runner-type peanut cultivars with early and late maturity. The study was conducted in the field in the 2021/2022 season, in a sandy soil environment in southeastern Brazil. Treatments consisted of runner-type peanut cultivars (early and late maturity) and the phenological stage of sampling (V4/V5, R2/R3, R4, R5, R6, R7, and R8). Average pod yields were 4.0 and 5.9 Mg ha
-1
for the early and late-maturity cultivars, respectively. Uptake of P, Cu, and Zn was linearly increased until stage R8. Nitrogen uptake continued until stage R7 for the early-maturity cultivars and stage R8 for the late-maturity cultivar. Potassium and B uptake did not increase after stages R5 and R6, respectively. For all other nutrients, maximum uptake occurred between stages R3 and R7. Leaf contents of all nutrients were within the sufficiency range, except Fe, which was higher than needed. Maximum macronutrient uptake (late-maturity cultivar) rates were 300, 28, 215, 76, 31, and 19 kg ha
-1
for N, P, K, Ca, Mg, and S, respectively, and the maximum micronutrient uptake rates were 2350, 95, 391, 659, and 414 g ha
-1
for Fe, Cu, Zn, Mn, and B, respectively. Maximum macronutrient removal rates were 210, 20, 48, 15, 7, and 12 kg ha
-1
for N, P, K, Ca, Mg, and S, respectively, and the maximum micronutrient removal rates were 967, 59, 236, 153, and 136 g ha
-1
for Fe, Cu, Zn, Mn, and B, respectively. Late-maturity cultivar had higher biomass production and greater uptake of all nutrients except K and Fe. The uptake of K and Fe was the same for both maturity groups.
A Hypergraph Analog of Dirac's Theorem for Long Cycles in 2-Connected Graphs, II: Large Uniformities
Authors: Kostochka Alexandr , Luo Ruth , McCourt Grace
Published: February 2025

Dirac proved that each $n$-vertex $2$-connected graph with minimum degree $k$ contains a cycle of length at least $\min\{2k, n\}$. We obtain analogous results for Berge cycles in hypergraphs. Recently, the authors proved an exact lower bound on the minimum degree ensuring a Berge cycle of length at least $\min\{2k, n\}$ in $n$-vertex $r$-uniform $2$-connected hypergraphs when $k \geq r+2$. In this paper we address the case $k \leq r+1$ in which the bounds have a different behavior. We prove that each $n$-vertex $r$-uniform $2$-connected hypergraph $H$ with minimum degree $k$ contains a Berge cycle of length at least $\min\{2k,n,|E(H)|\}$. If $|E(H)|\geq n$, this bound coincides with the bound of the Dirac's Theorem for 2-connected graphs.
The Minimum Spectral Radius of $tP_3$- or $K_5$-Saturated Graphs via the Number of $2$-Walks
Authors: Ai Jiangdong , Liu Pei , O Suil , Zhang Junxue
Published: February 2025

For a given graph $H$, a graph $G$ is $H$-saturated if $G$ does not contain $H$ as a subgraph, but for $e \in E(\overline{G})$, $G+e$ contains $H$ as a subgraph; the spectral saturation number of $H$, written $sat_{\rho}(n,H)$, is the minimum value of $\rho(G)$ in an $n$-vertex $H$-saturated graph $G$.
For a vertex $v \in V(G)$, let $l_2(v)$ be the number of $2$-walks starting from $v$. In this paper, when $G$ is an $n$-vertex $tP_3$- or $K_5$-saturated connected graph, for each vertex $v \in V(G)$, we prove the best lower bounds for $l_2(v)$ in terms of $n$ and $d(v)$, implying that $sat_{\rho}(n,tP_3)=\rho(F)$ and $sat_{\rho}(n,K_5)=\rho(S_{n,4})$, where $F$ is the $6$-vertex graph obtained from $K_3$ by attaching a pendant vertex to each vertex in $K_3$ and $S_{n,4}$ is the join of $K_3$ and $(n-3)K_1$.
Generalized Crowns in Linear $r$-Graphs
Authors: Zhang Lin-Peng , Broersma Hajo , Wang Ligong
Published: February 2025

An $r$-graph $H$ is a hypergraph consisting of a nonempty set of vertices $V$ and a collection of $r$-element subsets of $V$ we refer to as the edges of $H$. An $r$-graph $H$ is called linear if any two edges of $H$ intersect in at most one vertex. Let $F$ and $H$ be two linear $r$-graphs. If $H$ contains no copy of $F$, then $H$ is called$F$-free. The linear Turán number of $F$, denoted by $\mathrm{ex}_r^{\mathrm{lin}}(n,F)$, is the maximum number of edges in any $F$-free $n$-vertex linear $r$-graph. The crown $C_{1,3}$ (or $E_4$) is a linear 3-graph which is obtained from three pairwise disjoint edges by adding one edge that intersects all three of them in one vertex. In 2022, Gyárfás, Ruszinkó and Sárközy initiated the study of $\mathrm{ex}_3^{\mathrm{lin}}(n,F)$ for different choices of an acyclic 3-graph $F$. They determined the linear Turán numbers for all acyclic linear 3-graphs with at most 4 edges, except the crown. They established lower and upper bounds for $\mathrm{ex}_3^{\mathrm{lin}}(n,C_{1,3})$. In fact, their lower bound on $\mathrm{ex}_3^{\mathrm{lin}}(n,C_{1,3})$ is essentially tight, as was shown in a recent paper by Tang, Wu, Zhang and Zheng. In this paper, we generalize the notion of a crown to linear $r$-graphs for $r\ge 3$, and also generalize the above results to linear $r$-graphs.
Ökocímkék alkalmazása lehetőségei a közbeszerzési eljárásokban
Authors: Bajnóczi Gabriella
Published: February 2025

A fenntarthatósági szempontok a közbeszerzésben három módon tudnak megjelenni, a zöld, a szociális és az innovatív közbeszerzési eszközök alkalmazásával. Jelen cikk a zöld közbeszerzéseket vizsgálja, azon belül is az ökocímkéket, azok közbeszerzési eljárásokban betöltött szerepét. A zöld közbeszerzési eljárást az Európai Bizottság a "Környezetvédelmi szemléletű közbeszerzés" című közleményében olyan eljárásként határozza meg, „amelynek alkalmazásakor az ajánlatkérők azoknak az áruknak, szolgáltatásoknak és munkálatoknak a beszerzését részesítik előnyben, amelyek más, azonos rendeltetésű árukhoz, szolgáltatásokhoz és munkálatokhoz képest kisebb mértékben terhelik a környezetet”. A zöld közbeszerzés, ezen belül is az ökocímkék közbeszerzési eljárásokba való beépítése hozzájárulhat az Európai Unió körforgásos gazdaságra való átállásához, hiszen ez a környezeti fenntarthatósági célok elérése szempontjából is rendkívüli jelentőséggel bír. Nagyon fontos szempont lehet, hogy (1) a zöld szempontok alkalmazásával hozzájárulunk az adott termék, szolgáltatás elterjedéséhez, ez pedig ezen termékek és szolgáltatások árának csökkenéséhez is vezethet (nagyobb mennyiség – kedvezőbb ár); (2) ösztönözheti az innovációt és (3) mindenképp jó példát mutathat, amely hozzájárulhat a környezettudatos magatartás elterjedéséhez is.
“Geopolitical Geometry” in the Works of E.M. Primakov
Authors:   Astrakhan State University named after V.N. Tatishchev, Karabushenko P. L.
Published: February 2025

According to leading Russian analysts, the professional activity of E.M. Primakov in the most important government posts is a benchmark for subsequent generations of politicians and diplomats. But no less interesting is his experience of scientific description and analysis of current political events, in which he himself was a real participant. In this, he reveals himself to us not only as an outstanding politician of his time, but also as an independently thinking scientist who left behind a serious scientific legacy. And although we do not find a separate geopolitical theory in his works, Yevgeny Maksimovich constantly returns to the topic of geopolitics on the pages of his works, and from these fragments a very holistic vision of the geopolitical problem is formed, which later received the name "Primakov's doctrine". The present work is devoted to the disclosure of the main points of this doctrine. In the creative heritage of E.M. Primakov, two important topics of international relations are reflected - the role of political elites and their leaders in making responsible decisions and the practical implementation of geopolitical strategies of the leading powers of the world. He pays special attention to Russia and the problem of its return to the ranks of leading world powers. This work examines the issue of geopolitical structures reflected in the scientific works of E.M. Primakov. Such structures resemble geometric figures, which is why they received the corresponding name. Leaving aside the analysis of numerous scientific publications characterizing and evaluating Primakov's scientific legacy, we will focus our attention directly on the text of Yevgeny Maksimovich, which reflects his political worldview and professional thinking.

Development of a cryptographic protection system for information transmitted over open communication channels
Authors:   Pyatigorsk Institute (branch), North-Caucasus Federal University, Antonov V. F.
Published: February 2025

Introduction. The object of the study in this paper is the information security system. The purpose of this study is to develop a system of cryptographic protection of service information transmitted over open communication channels using the TCP/IP protocol between the TCP server and the client in the concept of an information security system. The paper provides examples of various algorithms for cryptographic protection of information when transmitting information over open communication channels. Materials and methods. This article discusses special encryption algorithms: DES, Triple DES, Rijndael, RC2 and RSA. The selection of the desired algorithm in a specific work session is carried out by selecting from the drop-down list. After specifying the type of algorithm, you should select the key length in the next drop-down list. The presence of several encryption algorithms and the presence of different key lengths will significantly improve the cryptographic strength of the system being developed, since when a sent message is intercepted, the algorithm and key length can be arbitrary, which will make it difficult for unauthorized decryption of messages. Results and discussions. World experience shows that success in the field of information security largely depends on the degree of use of the latest technologies that implement the majority of open cryptographic algorithms used. A huge number of organizations spend large amounts of money to ensure the security of information transmitted both outside and within the organization. Moreover, in the second case, as a rule, less attention is paid. But this is a pressing problem today and to solve it you need a software product. Of course, information security problems cannot be solved only by developing software products, because the human factor remains the weak point of any system. Conclusion. The solutions that are proposed based on the results of the work performed within the framework of this article will enable users to transmit and receive information through open communication channels, both within the organization and outside, thereby ensuring the protection of information from unauthorized access and modification.

BACKGROUND. According to the United Nations, by 2050, it is expected that every sixth inhabitant of our planet will have crossed the threshold of 65 years. This indicates an urgent need to identify the main barriers that arise when providing medical care in order to improve the process of organizing medical services for people over working age.

AIM. To study the characteristics of psychological and communication barriers (problems in defining the model of the doctor-patient relationship) in the Russian Federation when providing medical services to people over the working age, with the aim of developing recommendations based on these findings to eliminate these obstacles.

MATERIALS AND METHODS. In this study, a questionnaire was used, consisting of three blocks and 89 questions. The data were analyzed using Statistica 10, Stata, and R-Studio programs. The Pearson’s chi-square test was used to compare categorical variable distributions. A generalized linear model was used to test the impact of individual characteristics on the outcome variable. The Mann-Whitney U and Kruskal-Wallis tests were used to analyze differences between samples with abnormal distributions.

RESULTS. A total of 3,942 individuals participated in the survey. Among the study participants, the most prevalent psychological barrier to engaging with the healthcare system was fear of visiting a medical facility associated with the potential for detecting new illnesses or worse outcomes (66.6%). Approximately half of respondents indicated that this could serve as a reason for not seeking medical attention (52%). The most commonly reported communication barriers included the need for assistance in understanding doctor’s prescriptions (27.7%), difficulty understanding doctor’s speech due to hearing problems (18.5%), the frequent use of incomprehensible terminology by doctors (25.7%), and approaching problems in a formal manner or not delving deeply enough (24%)

CONCLUSION. The research conducted will allow us  to make managerial and organizational decisions in  a more purposeful and reasonable manner, in  order to  create a  trustworthy environment, improve the quality of  doctorpatient communication, and provide necessary psychological support during medical care for people over working age.

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder where there is a disruption in the fundamental processes of socialization, communication, and learning. A percentage of autistic individuals do not develop speech, and when it occurs, it is typically altered; however, there are reports of a predisposition to learning a second language to the detriment of the first. Objective: To evaluate the predisposition for acquiring English as a second language and motor development in Brazilian children with ASD. Materials and method: The cross-sectional study had a convenience sample composed of 16 children diagnosed with ASD, with chronological ages between 6 and 11 years old. After being approved by the Ethics and Research Committee of UniEVANGÉLICA and constituted by screening, the participants took a placement test where their level of confidence and fluency in the English language was assessed. For the motor assessment, the Revised Psychoeducational Profile (PEP-R) (Schopler, Reichler, Bashford, Lansing & Marcus, 1990) was applied, aiming to evaluate the developmental age in seven areas: imitation, fine motor coordination, gross motor coordination, visuomotor coordination, perception, cognitive performance, and verbal cognition. Results: The results will be statistically analyzed assuming a significance level of p≤0.05, with the aim of promoting communication and cognitive interventions and providing a better quality of life in the language development of the autistic child.
ENERGY EFFICIENCY AND SUSTAINABILITY: ANALYSIS OF GENERATION, ENERGY QUALITY, AND ENVIRONMENTAL MANAGEMENT INDICATORS OF THE UNIEVANGÉLICA PHOTOVOLTAIC PLANT IN ANÁPOLIS, GOIÁS (2019-2022)

Electricity is one of the most widely used forms of energy in the world, primarily generated by harnessing the energy potential of water in hydroelectric plants. However, it can also be generated in wind farms, thermal power plants, solar plants, nuclear plants, among others. Therefore, in Brazil, the generation of electricity through the photovoltaic process is extremely promising – solar generation in a clean, renewed, and sustainable way, as the country has an extensive territorial area with high levels of solar irradiation. In this sense, there are several research works involving the financial and technical reasons for the installation of photovoltaic plants. However, little is known or explored about the environmental, scientific, social, and architectural impacts/benefits, as well as the vision for studies and research on the installations of Photovoltaic Plants. Therefore, this work aims to analyze the energy efficiency and sustainability patterns of the UniEVANGÉLICA Photovoltaic Plant, and correlate them with the environmental benefits achieved through the generation of clean, renewable, and sustainable electricity. To this end, the following methodologies are being used: Theoretical Research – in order to understand the State of the Art and/or Scientometrics, the platforms Web Of Science, Science Direct, Scielo, Scopus, ACM, and others are being used; Practical Research - for conducting technical studies on the transmission of generated energy, quality of the generated energy, and efficiency of the system of this electric power generation system through the photovoltaic process, the Energy Efficiency Laboratory of UniEVANGÉLICA (LEEFoto) is being used. As expected results, it aims to generate knowledge in the area of management and energy efficiency of photovoltaic plants as well as validations of methodologies to assist in decision-making for the use of clean and sustainable electricity generation, with an emphasis on the generation indicators of the UniEVANGÉLICA Photovoltaic Plant and environmental indicators (solar radiation, wind speed, and climate changes) of the municipality of Anápolis-Goiás.
ENVIRONMENTAL EDUCATION AND CONSERVATION UNITS: A NECESSARY PARTNERSHIP
Authors: Santos André Sousa , Braz Vivian da Silva
Published: February 2025

The environmental crisis and social reproduction models do not prioritize the protection of biodiversity, causing a large portion of natural resources to reach a state of exhaustion. One of the alternatives to minimize the crisis is the creation of Conservation Units, which in turn are suitable places for the development of environmental education activities, a partnership that represents a two-way street that can benefit both parties.
THE ALTAMIRO DE MOURA PACHECO STATE PARK – PEAMP IN THE CONTEXT OF THE OCCUPATION OF MATO GROSSO GOIANO
Authors: Silva Hérica Ozana da , Boggione Giovanni de Araújo
Published: February 2025

The Cerrado occupies about 25% of Brazilian territory (CBC/ICMBio, 2022). It is the second largest biome in the country, surpassed in area only by the Amazon. It is home to important natural resources, as well as global economic interests, given the scale of agribusiness, an economic activity responsible for a large part of the economic development of the Brazilian Midwest, generating improvements in the infrastructure of the States and producing food on a large scale, even though the variety of products is limited. It is in this duality that the concern for the conservation of the Cerrado has been growing, both in the academic community and in society at large.
In the context of natural resource conservation, the development of public policies for this purpose is essential, as well as the enforcement of current environmental legislation. In this sense, among the public policy mechanisms related to the area of environmental conservation, we have Conservation Units – CUs, especially those with full protection.
This work (dissertation in progress at the PPGSTMA of UNIEVANGÉLICA) aims primarily to research the creation of the Altamiro de Moura Pacheco State Park - PEAMP, a Full Protection Conservation Unit managed by the State of Goiás, located along the BR-153, near the state capital, as well as to analyze its current landscape and discuss its importance for the environmental conservation of the Cerrado, especially in the context of the Environmental History of Goiás and the region of Mato Grosso de Goiás – MGG.
The PEAMP was created by State Law No. 11,878 on December 30, 1992. It is located in the watershed of the Ribeirão João Leite, adjacent to the Environmental Protection Area – APA, as well as the João Leite State Park.
It is an important remnant of the native vegetation of the MGG region, an extension of forest phytophysiognomy located in the central-southern part of Goiás (Barbosa et al. 2020) that includes, among other municipalities, parts of Goiânia and parts of Anápolis (Giustina et al. 2020).

Authors: Sobreira Patrícia de Albuquerque , Rosseto Lucimar Pinheiro , Braz Vivian da Silva
Published: February 2025

The theme of the study is the practice of scouting and its psychoeducational and socio-environmental benefits observed in children and adolescents. This investigation will encompass the historical relationships of the Scout Movement; a field study will be conducted at the Bernardo Sayão Scout Group and observations will be made regarding the scouts' concern with environmental issues and sustainability through the "Tribe of the Earth" activity. The psychosocial benefits of children participating in camping with outdoor activities in nature and the perception of their families will be verified. Through the obtained results, a data triangulation will be conducted to better understand its objectives. The theoretical framework will be based on the concepts of Scouting, Child and Adolescent Rights, Environmental Law, Education, Ecological Psychology, drawing on different theoretical contributions and engaging with various authors. The methodology will be a research with a qualitative-quantitative approach, hermeneutic method, data collection at the Juvenile Court, analysis/research of legislation, questionnaires, fieldwork, and content analysis technique. Diagnostic studies will be important to visualize the current scenarios that these initiatives face and to envision perspectives and strategies capable of enhancing them. Considering that scouting plays an important role in the construction of values and socio-environmental awareness among participants, this research aims to understand the psychosocial benefits arising from proximity to nature and to verify the restorative effect that natural environments provide to children and adolescents.
