Метою даного дослідження було визначення впливу рослинних інгредієнтів на подовження терміну зберіга-ння кров’яних ковбас та на їх сенсорні, фізико-хімічні, структурно-механічні властивості. Встановлено, що кров’яна ковбаса за розробленою технологією з додаванням зеленої гречки та порошку баклажанів (10 %) має кращі сенсорні властивості порівняно з контролем. За фізико-хімічними показниками розроблена ре-цептура кров’яної ковбаси не відрізняється від контрольного зразка. Встановлено, що ввведення до рецеп-тури рослинних інгредієнтів дозволяє збалансувати співвідношення білків до жирів (1 : 1.34), що наближено до вимог раціонального харчування (1 : 1) порівняно з контролем (1 : 2.02). Визначено, що розроблена технологія позитивно впливає на стабільність системи та здатність утримувати воду. рН збільшується з 6.35 (контроль) до 6.52 (дослід), знижується вміст слабоз’вязаної вологи з 13.74 % до 5.74 % в дослідному зразку. Мікробіологічні показники відповідали встановленим вимогам. Введення нетрадиційної сировини пригнічує розвиток мікроорганізмів, що дозволяє подовжити термін зберігання готового продукту в нату-ральній оболонці на 24 год порівняно з традиційними рецептурами, що підтверджується змінами кислот-ного і перекисного числа. Результати проведених досліджень підтверджують ефективність та технологічну доцільність додавання порошків з баклажану та крупи зеленої гречки до технології кровяних ковбас.

Short-term functional outcomes and treatment trends for branch atheromatous disease and lacunar infarction: a retrospective cohort study of a nationwide multicenter registry
Authors: Fujiwara Gaku , Oka Hideki , Fujii Akihiro
Published: July 2024

Objective: Branch atheromatous disease (BAD) is a form of ischemic stroke that presents with imaging findings similar to those of lacunar infarction, but has a different pathogenesis and is known to cause progressive paralysis. Due to regional variations, the epidemiology of BAD is not well understood, and its relationship with the functional prognosis remains unclear. Using a comprehensive Japanese stroke database, we investigated its epidemiological characteristics and associations with functional outcomes.Methods: In this multicenter cohort study, we retrospectively analyzed data from 27 hospitals that contributed to the Saiseikai Stroke Database (2013–2021). We used multivariable logistic regression to calculate adjusted odds ratios (aORs) with 95% confidence intervals (CIs) of BAD compared with lacunar infarction (LI) for functional outcomes at discharge. Ischemic stroke caused by BAD or LI was included, and demographic characteristics and clinical data were evaluated and contrasted between BAD and LI.Results: Of the 5,966 analyzed patients, 1,549 (25.9%) had BAD and 4,434 (74.1%) had LI. BAD was associated with worse functional outcomes (aOR, 2.77; 95% CI, 2.42–3.17; relative to LI) and extended hospital stays (median 19 days for BAD vs. 13 days for LI). Moreover, aggressive treatment strategies, including the use of argatroban and dual antiplatelet therapy, were more common in BAD patients.Conclusion: BAD presented worse functional outcomes and longer hospital stays than LI, necessitating treatment plans that take into account its progression and prognosis.

Chitin and Its Derivative Chitosan: Distribution in Nature, Applications, and Technology Research (A Review)
Authors: Perelygin Vladimir V. , Zharikov Mikhail V. , Zmitrovich Ivan V. , Nekrasova Tatyana A.
Published: July 2024

The present review highlights the chitin/chitosan as biopolymers that are promising for biomedical research development. Our goal was to assess the potential for practical use of these biopolymers and to summarize information on traditional and innovative technologies for their production and purification. The widespread occurrence of chitin and chitosan in nature as well as the unique chemical and biological properties of chitosan are reasons of growing interest in the use of the latter in several pharmaceutical fields. The main stages of chitin extraction and its further modification into chitosan are deproteinization, demineralization, deacetylation, and the main methods of chitosan purification are filtration, dialysis and reprecipitation. The profitability of the production of chitin/chitosan from crustaceans and edible mushrooms is approximately at the same level. The cost of mushroom products can be reduced by using agricultural or forestry waste as nutrient substrates. This makes the use of fungi as sources of chitin/chitosan in forested regions a rather promising issue.

Published: July 2024

The prevalent histological variant within differentiated thyroid carcinoma is papillary thyroid carcinoma, also known as PTC. The study investigated the clinical performance of serum hsa_circ_0001955 in predicting the prognosis of PTC treated with radical thyroidectomy and iodine 131 nail clearance. The relative expression of serum circ_0001955 of PTC patients was detected before and after accepting radical thyroidectomy combined with 131I thyroid remnant ablation by RT-qPCR. Serum thyroglobulin (Tg) and thyroglobulin antibody (TgAb) levels were quantified by an automatic chemiluminescence immunoassay analyzer. Multivariate logistic regression analysis was employed to investigate the risk factors associated with the prognosis of PTC patients with postoperative 131I therapy. The serum circ_0001955 levels in 127 PTC patients were higher than that in 96 multinodular goiter patients and 110 healthy controls before treatment and had diagnostic values for PTC patients. After 131I treatment, serum circ_0001955 levels and Tg value have a correlation with potential recurrence (WBS positive). Serum circ_0001955, Tg, and TgAb value, and their combination may have diagnostic value in predicting recurrence. Serum circ_0001955 levels in patients with PTC after radical thyroidectomy and iodine 131 thyroidectomy may help predict recurrence.

Community-acquired pneumonia is one of the most common acute infectious diseases, especially in organized groups. Community-acquired pneumonia in military personnel is a serious problem of the medical service and is diagnosed 2–3 times more often than among civilians. The purpose of the study. To study the clinical features of the action of “Immunovac-VP-4 ®” in the complex treatment of community-acquired pneumonia in new recruits. Materials and methods. The study group included 88 conscripted military personnel from among the new recruits who were hospitalized with a diagnosis of mild community-acquired pneumonia. The main group of the study included 35 patients receiving basic antibacterial therapy in combination with the therapeutic vaccine “Immunovak-VP-4 ®”. The control group included 53 patients who received only standard basic antibacterial therapy. Results. In the main study group, the frequency of repeated respiratory infections in all nosologies was lower than in the control group, statistically significant differences were noted in relation to pneumonia and acute rhinosinusitis. A decrease in the level of IL-1β in blood serum was revealed after 15 days (p = 0.05) and 6 months after discharge from the hospital (p = 0.002) in the main group compared with the control group. After 15 days, in the group of patients receiving “Immunovak-VP-4 ®”, there was a decrease in IL-6 levels relative to the baseline (p = 0.04) and it became lower than the control group (p = 0.04). Conclusion. The use of the “Immunovak-VP-4 ®” vaccine can be considered as a way to improve the treatment of community-acquired pneumonia: it can be a drug for treatment, prevention of complications, and an instrument in immunorehabilitation. The use of “Immunovak-VP-4 ®” in the complex treatment of community-acquired pneumonia of mild course is accompanied by a decrease in the activity of systemic inflammation: a decrease in serum levels of IL-1β, IL-6.

Published: July 2024

Recently, due to the increase in intestinal diseases, there has been a tendency to increase the number of stomatized patients. It has been statistically proven that the elimination of intestinal stomas is fraught with the development of inflammatory phenomena in the area of the removed stoma in the early postoperative period, leading to the development of parastomal abscesses and phlegmon, which in turn are risk factors for the formation of parastomal hernias in the long-term postoperative period. A parastomal hernia makes it difficult to care for the stoma, thereby reducing the quality of life. The presented work provides an overview of the literature data on various methods of preventing the formation of parastomal hernias. In addition, methods for closing a stomal wound during the elimination of intestinal stomas are presented in order to prevent the development of complications after reconstructive operations.

Incentivo aos deslocamentos sustentáveis: uma análise da caminhabilidade em Catalão (GO)
Authors: Duarte Milena Pereira , Metsavaht Yan de Pádua Castro
Published: July 2024

Como forma de ampliar a qualidade da mobilidade urbana e contribuir na redução dos impactos ligados aos efeitos das mudanças climáticas, a caminhabilidade é o meio de locomoção mais fundamental e energicamente eficiente a ser promovido, especialmente nas cidades médias, onde as populações têm crescido aceleradamente e o planejamento do sistema de transporte urbano muitas vezes é debilitado. Dessa forma, o objetivo do artigo é identificar as condições de infraestrutura que se encontram as calçadas da região central na cidade de Catalão (GO), compreendendo se há incentivos para que a caminhabilidade seja estimulada. Para isso, é utilizado o Guia “8 Princípios da Calçada: Construindo cidades mais ativas”, desenvolvido pela World Resources Institute, que qualifica categorias essenciais quanto às infraestruturas das áreas de passeio. A partir disso, é possível compreender se as cidades médias têm buscado incentivar uma mobilidade mais sustentável, valorizando a experiência dos pedestres. Nesse sentido, a pesquisa evidencia que, mesmo em regiões centrais, a maioria dos percursos não apresenta um dimensionamento adequado e não preza pela acessibilidade universal. A proposta metodológica aplicada se mostra eficaz, embora não contemple todas as ambiências e elementos envolvidos na perspectiva dos indivíduos durante a caminhada. Com isso, evidencia-se os principais princípios a serem aprimorados pela gestão municipal para que a vivência do pedestre seja priorizada, o que é capaz de tornar as cidades mais resilientes e adaptadas a um ambiente climático em constante transformação.

Published: July 2024

Muito se fala a respeito das “cidades inteligentes” que transmitem a ideia de tornar mais célere e eficiente a detecção e os apontamentos de eventuais problemas e suas possíveis soluções, estreitando a relação entre o cidadão e o tomador de decisões. A importância de um Plano de Drenagem para as cidades, de modo a controlar e diminuir os impactos naturais sobre os espaços urbanos e promover uma melhor gestão das águas pluviais é fundamental. Tornar as cidades mais resilientes quanto aos seus sistemas de drenagem tem a ver com soluções que levem as cidades a funcionarem como “esponjas”, ou seja, que elas se tornem capazes de absorver o fluxo de água superficial. Este artigo propõe um planejamento permacultural em um trecho do Parque do Povo, localizado na cidade de Presidente Prudente - SP, com a produção e o uso de cartografias temáticas socioambientais, pensando-se na busca de cidades mais resilientes. No local há recorrentes sinistros ambientais com alagamentos, provocando perdas sociais, ambientais e econômicas para a cidade. Após entender o contexto, levantar demandas e sinistros, e produzir cartografias socioambientais, elaborou-se um planejamento permacultural com tecnologias ambientais de infraestruturas verdes e azuis como modelo de proposta para a região. Utilizou-se da metodologia da permacultura que ocorre em 4 etapas: setorização, demandas, zoneamento e ambiências/usos. A hipótese aqui levantada: geotecnologias e cartografias temáticas (sociais, humanas e sensíveis), alinha-se com a metodologia clássica da permacultura e se aprofunda na direção de melhorar o entendimento dos contextos, das demandas e dos resultados das propostas.

La inteligencia social y sus implicaciones en la evolución de la mente
Authors: Chaves Castaño Liliana
Published: July 2024

Este artículo discute dos posturas teóricas sobre la evolución de la mente humana. La teoría de Calvin (1996, 2004) propone la organización mental como producto derivado de la adaptación a condiciones ambientales complejas y cambiantes. En contraste, la teoría de Humphrey (1998, 2002) argumenta que la mente humana y sus particulares características son el resultado de adaptaciones al entorno social. Estas dos posturas teóricas se acompañan de una fuerte evidencia empírica que amplía la investigación al estudio cada vez más fascinante de la mente, su organización, evolución y desarrollo.
A la sombra del otro: sobre los vínculos al final dela vida
Authors: Ruiz osorio Mario Alberto
Published: July 2024

En la experiencia de morir, el enfermo vivencia algunas situaciones que están determinadas por el sufrimiento producido por la enfermedad y la proximidad del final de su vida. Particularmente, los vínculos con el otro se transforman en razón de la dificultad de aceptar la condición de mortal que le impone la enfermedad avanzada. La mentira, la conspiración del silencio, la agresividad, son entre otras, las expresiones de un proceso que exige al psiquismo del enfermo una gran cuota de padecimiento.  Como producto de una investigación cualitativa con enfermos al final de la vida, y la lectura de textos literarios de apoyo, se ofrecen algunos hallazgos en el presente artículo con el fin de ilustrar, en algo, la fenomenología, de la experiencia de morir.

Pontocerebellar hypoplasia caused by the TSEN54 mutation: clinical and electroencephalographic characteristics based on 3 cases
Authors: Bobylova M. Yu. , Abramov M. O. , Mukhin K. Yu.
Published: July 2024

Pontocerebellar hypoplasia caused by the TSEN54 mutation is a severe hereditary disease with an autosomal recessive mode of inheritance, which is characterized by a combination of epileptic encephalopathy, motor disorders in the form of spasticity and hyperknesis, dysphagia and central respiratory failure. At birth there may be multiple joint contractures, muscle hypotonia, and central respiratory failure. Epilepsy occurs in 82 % of cases. Seizures may begin after birth, with an average age of onset of 2.5 years. Various types of seizures are noted (febrile seizures, bilateral tonic-clonic, atypical absence, myoclonic, tonic, focal and atonic seizures), usually resistant to antiepileptic drugs. Magnetic resonance imaging reveals hypoplasia of the pons and cerebellum, which makes it possible to distinguish this disease from cerebral palsy. In the literature there are few descriptions of the clinical picture and electroencephalogram of patients. In this regard, our description of 3 cases of epilepsy and electroencephalographic data in patients with TSEN54 mutation (all female) is of interest to child neurologists and epileptologists.

The etiology of cerebral palsy in children with intrauterine hypotrophy at birth and developmental delay is often explained by chronic intrauterine hypoxia. However, children with muscle hypotonia and developmental delay require genetic examination. The aim of this study is to report a case of mitochondrial disease caused by FBXL4 gene mutations and to identify main diagnostic criteria for mitochondrial DNA (mtDNA) depletion syndromes (MDS) in early childhood. Mitochondrial DNA depletion syndrome-13 is associated with FBXL4 gene mutations located in the 6q16.1–q16.27 locus. This disorder was first described in 2013 by P.E. Bonnen and X. Gai independently. MDS are a clinically and genetically heterogeneous group of diseases inherited by an autosomal recessive type and caused by mutations in genes that support the biogenesis and integrity of mtDNA. Encephalomyopathic mtDNA depletion syndrome-13 (MTDPS13) (OMIM: 615471) is an exceedingly rare autosomal recessive disease caused by biallelic mutations in the FBXL4 gene (MIM: 605654) with an estimated prevalence of 1 case per 100,000– 400,000 newborns. The disease onset is usually observed in the neonatal period; 75 % of patients develop symptoms by the age of 3 months. In the majority of cases, mtDNA depletion syndrome-13 manifests itself in the early neonatal period; however, in some patients, the disease onset was registered by the age of 24 months. The disease is characterized by encephalopathy, hypotension, lactic acidosis, severe developmental delay, and changes in the area of basal ganglia revealed by magnetic resonance imaging of the brain. FBXL4-related encephalomyopathy is a multisystem disease primarily affecting the central nervous system, heart, and liver. It is characterized by different clinical manifestations such as lactic acidosis, developmental delay, generalized hypotension, nutritional disorders, and growth retardation. Some patients demonstrate specific facial features, including prominent forehead, sinus-shaped folds, thick eyebrows, long eyelashes, epicanthus, short eye slits, hypertelorism, wide and depressed nose bridge, long and smooth labial groove, thin upper lip, and low-set ears. The disease prognosis is extremely poor; most children die before the age of 4 years. Approximately half of the patients suffer from microcephaly and hyperammonemia. The outcome varies; death was reported in 30 % of cases. Mean time to death was 3 years (median – 2 years). The diagnosis is crucial for medical and genetic counseling and possible prenatal diagnosis.
Methodological Foundations for the Formation of Universal Educational Actions in the Context of the Ideas of the V.S. Mukhina’s Concept “Phenomenology of Personality Development and Being”
Authors: Basyuk V.S. , Melkov S.V.
Published: July 2024

The article considers the methodological foundations for the formation of universal educational actions as the basis for the creation of metasubject results of general secondary education and it examines the key ideas of cultural-historical and system-activity approaches that are fundamental in achieving the main results of school education. The authors substantiate the importance of implementing these ideas at the level of federal state educational standards in order to systematize, standardize and regulate the activities of teachers in a modern school. The article also reveals the interrelation of the currently existing methodology for the formation of universal educational actions with the ideas of the concept of the V.S. Mukhina's scientific school «Phenomenology of personality development and being». Here’s also substantiated the productivity of considering V.S. Mukhina's scientific ideas on the mental mechanisms of identification-isolation and factors determining the development of the personality, including: 1 – genotypic prerequisites, as methodological foundations for the formation of cognitive, communicative and regulatory universal educational actions; 2 – external conditions (the reality of the objective world, the reality of figurative and symbolic systems, natural reality, the reality of the socio-normative space); 3 – the internal position of the personality. The authors consider the interrelation of personal educational outcomes with universal educational activities as well. They also defend the idea that the prior purpose of education is personal development.

Published: July 2024

The paper examines the development of the organic production sector in Bulgaria in recent years, particularly emphasizing the main challenges and problems and the need for close monitoring, support and re–energisation of the sector. Its potential, trends and multidimensional implications for the environment, society and local communities represent an important research subject and are the focus of the INVEST Regional Living Lab in Bulgaria, established by the University of Agribusiness and Rural Development. The Living Lab applies the quadruple helix approach to work on open innovations that fits very well the research task of identifying challenges and opportunities for the development of organic production in Bulgaria. Combining primary data, case studies and facticology from the terrain that highlight the most pressing issues for regulation and funding, the research provides a two–level view of trends on organics at EU level and the local photography. The results suggest that improving the capacity of chain operators, access to organic markets and research on fast–growing ones can expand the potential of opportunities, integrating this research with other research tasks in the INVEST Living Laboratory in Bulgaria, especially those related to alternative food networks and relationships between urban and rural territories, climate change, agriculture and tourism. Good practices, green innovations and expertise within the ecosystem to implement efficient solutions remain essential for the vision and expansion of the sector.
CIRCULAR ECONOMY AS A TOOL FOR SUSTAINABLE DEVELOPMENT: A THEORETICAL PERSPECTIVE
Authors: Deksne Juta
Published: July 2024

Climate change, depletion of natural resources, social inequality and poverty, a lack of food resources, etc. issues related to world sustainable development has become increasingly relevant in the last 50 years, negatively affecting people's opportunities, and living standards in various countries. Despite these problems, the average level of wealth of the population in the world is gradually increasing over time. Considering forecasts on population growth by the end of the 21st century, it must be admitted that the current world-dominant linear economic model is fully unsustainable in resource consumption, as there is a natural barrier to economic growth. The aim of the present research study is to explore the potential of the circular economy as a tool for achieving sustainable development, based on a theoretical framework. This paper was built based on a broad literature review to examine the limitations and conceptual gaps of the circular economy concept as a tool for achieving sustainable development. It has been concluded that the circular economy concept undeniably has huge potential to promote sustainability within planetary boundaries as well as it can be implemented to decouple economic growth from the utilization of finite resources. However, a broader analysis of the circular economy concept allows us to assert that to date, a clear and effective approach for the transition to this economic model, affecting all areas of sustainable development (i.e. environmental, economic, social) has not been developed. In addition, the circular economy concept is still evolving, there is a tendency to view the circular economy concept holistically, covering various sub-concepts of the circular economy under the common Sustainable Circular Economy concept's umbrella.

GREEN HUMAN RESOURCE MANAGEMENT AS A COMPONENT OF SUSTAINABLE ORGANIZATIONAL DEVELOPMENT IN ENVIRONMENTAL AND NATURAL ECONOMICS
Authors: Vasilev Valentin , Stefanova Dimitrina , Icheva Monika
Published: July 2024

A growing number of public personalities, politicians, non-profit organizations, and members of civil society are demonstrating their social duty and dedication by adopting a green philosophy that focuses on three key areas: the environment, human well-being, and the green economy.
The terms "green management", "green public procurement", "green marketing", "green human resource management" and "green PR" are becoming more and more popular to improve the environmental condition. Because of their mutual dependence, applying one idea promotes the growth and advancement of another.
This study attempts to present a research model, on the one hand, emphasizing the thesis that environmental management should be viewed as a moral concern rather than an adaptable procedure and that it can influence as a source of competitive advantage by providing strategic and economic advantages [1]. The idea that the application of green practices in human resource management extends beyond the implementation of environmental protection initiatives and includes the formulation of policies and practices that support sustainable development and people management is another popular hypothesis in the field. Taking into consideration the interaction between institutions and human resources, the concepts of meaning, value, and integrative communication are strengthened in this context to create ideal conditions for the implementation of "green ideas" with a sustainable outcome. The conceptual linking of these management fields is presented in a 'management waterfall for re-innovation' model for positive, integrative 'green' organizational behavior.
The aim of the study is to make a comparative analysis of the challenges facing the green management of human resources, summarizing and presenting some interesting ideas in this scientific field. Through comparative analysis, key characteristics are summarized and conclusions are drawn for the improvement of these processes.

Published: July 2024

The failure of providing reliable water supply with standard water quality to the households is seen as a specific aspect of the water crisis. In this study, the drinking water supply of the households in Northeastern region of Bulgaria (Varna, Shumen, Dobrich, and Targovishte districts) for the period 2010-2021 was studied and analysed. During the studied period, the relative share of population affected by lack of drinking water supply for over 180 days per year varies between 0.0% in 2011 to 0.7% in 2020 of the total percentage of affected population on national scale. For Varna and Dobrich districts, the share of the affected population from prolonged interruptions in the water supply does not exceed 1%. The most severely affected is the Targovishte district’s population, where between 8.8% in 2010 and 24.3% in 2020 experience water supply regime with long, regular interruptions of water supply. In the municipality of Omurtag, approximately 80% of the population does not receive continuous water supply. Households in some of the villages in this municipality receive regulated water supply once every 480 hours. Based on the analysis, settlements with a regime of water supply and poor drinking water quality were identified, as well as the time intervals of supply interruption for the period studied. The main reasons for the manifestations of this specific aspect of the water crisis in Northeastern region of Bulgaria were identified. The shortage of water and the inability to provide households with the necessary water quantities with the required quality confronts Bulgaria with an ever-growing problem, the solution of which requires a complex institutional response, including from the water supply and sewerage sector.

The process where pristine graphite is subjected to a solvent treatment seems simple and scalable and has attracted the attention of researchers over many years.  However, for successful exfoliation, overcoming the van der Waals attractions between the adjacent layers of graphite is necessary. Over time, several methods have been created to overcome the attraction between layers. Graphene’s liquid phase exfoliation (LPE) occurs due to the strong interactions between the solvent molecules and the basal planes of graphite, overcoming the energetic resistance to exfoliation and subsequent dispersion. Ultra sonication used for exfoliation can produce single or few layered graphene flakes. During sonication the sound waves propagate through liquid medium in alternating high- and low-pressure cycles, strong mechanical and thermal energy released by acoustic cavitation results in splitting up large particles into fine ones and dispersing them. Simultaneous insertion of solvent and/or intercalation molecules in between the graphite layers takes place supporting graphite separation into graphene layers. ; The dispersion capacity of graphene flakes depends on how appropriate the solvent properties are to the corresponding properties of graphene, such as surface tension, Hildebrand, and Hansen solubility parameters. Only certain solvents can disperse graphene well and form a dispersion appropriate for specific future applications. In addition, after exfoliation by ultra sonication graphene flakes aggregation due to the van der Waals attractions must be overcome to prepare in long-term stable dispersions of nanometres-size graphene sheets. ; The research has focused on the preparation of stable dispersion ready for transfer without intermediate processes to the Kevlar fabrics. An experimental comparison of the potentials of the 4 solvents for the application resulted in three corresponding to the intended use, two of them examined in detail, supplementing the composition of the LPE liquid medium with triethanolamine to obtain sufficient performance graphene coverage on Kevlar textile fibres.

Published: July 2024

Any success or failure of the manufacturing industry, according to scientists, indicates the processes that are going to occur in the entire national economy in the future as well as the overall current state of the national economy. In Latvia, small and medium enterprises engaged in the manufacturing industry make up the largest proportion of market sector economically active statistical units, and the value added generated by small and medium manufacturing enterprises represents the largest proportion of total value added generated by the manufacturing industry. The research aims to identify and assess factors in the performance and development of the manufacturing industry and small and medium manufacturing enterprises in Latvia. The research employed general scientific research methods: monographic, descriptive and graphic as well as analysis and synthesis. The Cobb-Douglas model was used to assess the situation in the manufacturing industry and identify the effects of factors on economic growth. The research identified and assessed the factors in the performance and development of the manufacturing industry and small and medium manufacturing enterprises in Latvia.

Authors: Dimitrova Vihra , Pavlov Plamen
Published: July 2024

The present scientific paper examines a new approach to sustainable management, related to the concept of social farming. The socio-ecological nature of the social farming makes it a valuable asset, contributing to the welfare, wellbeing, intercultural learning, labour integration and social inclusion of the most disadvantaged groups of society. The potential of the social farming for achieving sustainable development in the rural areas is enormous, including social entrepreneurship and social innovation, increased employment rates and incomes, social inclusion, training, recreation, innovation and environmental protection. Social farming, as a multifunctional model, contributes both, to the public welfare and the alternative entrepreneurial business model. The proposed systemic model represents a more comprehensive approach to the complex nature of the social faming. The results of the study encompass the theoretical review of the concept, an effective social farming model and the existing problem-solving opportunities.

The purpose of the study is to substantiate the theoretical and methodological provisions and develop practical recommendations for the development of green entrepreneurship for the post-war recovery of Ukraine based on the experience of Latvia. The scientific novelty of the study lies in solving an important scientific and applied task - further development of theoretical aspects of green entrepreneurship, substantiation of the relationship between eco-innovation, green growth strategies and environmental policy in the context of sustainable development. The study uses general scientific and special methods: scientific abstraction, deduction, analysis and synthesis, systemic and critical analysis, structural and logical, ascent from the abstract to the concrete, and statistical analysis. It is proved that the Latvian business ecosystem is adapted for highly efficient investments and innovations in the field of green technologies. The study identified guidelines for environmental policy that will promote the development of green entrepreneurship, increase the density of green infrastructure, extend the life cycle of high value-added products manufactured in the country, reduce waste and encourage recycling. The importance of studying the experience of Latvia in strengthening the strategic framework for sustainable development and green growth for the post-war recovery of Ukraine is substantiated. It is determined that improving the quality of environmental infrastructure and services, as well as investing in innovation potential, will ensure the decoupling of economic growth from resource use and environmental depletion and accelerate the transition to a closed-loop economy. The authors propose the components of a «green» post-war recovery of Ukraine in the context of its further European integration.
MULTIFUNCTIONAL ORCHARD MODEL FOR SYNERGISTIC PRODUCTION

Published: July 2024

The world's growing population requires increased crop yields for their feeding. In food consumption, fruit is relied upon as one of the sources of vitamins. This necessitates an increase in perennial fruit plantations. Another important product is the consumption of animal foods and products. On the other hand, a growing population is in dire need of electrical energy to meet its needs. This also requires an increase in the production of this type of energy. Worldwide, in order to protect the environment and reduce the consumption of raw materials, it is necessary to produce electricity from RES.
This article discusses a model of complex production of plant production from an orchard, animal production and energy from a photovoltaic plant in a unit of arable area.; In practice, these are three separate productions to meet the needs of the population, which, however, have the same area and are located in the same place. Using the specifics of the individual productions, an attempt was made for the joint use of the areas, in which case it is possible to eliminate part of the various technological operations or serve as a basis for the other type of production. Such can be the irrigation of the plantation, the presence of shade from photovoltaics, fertilization of the plum plantation by the animals, fresh food for the animals, etc. The interrelations and the main points in the symbiotic production are given. The model can also be used in other types of joint "green" proceedings, after clarifying their specifics.
