Authors: Iqbal Irfan , Zeb Nayyra
Published: November 2024

Grounded on the conservation of resource theory and deontic theory of justice this study anticipated a model that examines the Observer reactions to abusive supervision that links to feedback avoidance and silence towards the supervisor. A physical and online survey was conducted, collecting data from approximately five hundred healthcare professionals in South Punjab. Observed abusive supervision shows a positive association with feedback avoidance and silence towards supervisors the moderating effect of social support reflected in such conditions of facing abusive supervision employees are looking for social support so social support moderates the indirect effect of observed abusive supervision on silence towards supervisor via feedback avoidance such that the indirect effect will be weaker when a high level of social support. We conclude our findings for research on observed abusive supervision, feedback avoidance, silence towards the supervisor, and social support.

Authors: Shafi Shumaila , Akbar Waqas , Rafiq-uz-Zaman Muhammad
Published: November 2024

This study examines the impact of teaching strategies on prejudice and intergroup relations among secondary students in public high schools in Pakistan’s Lodhran district. Using a descriptive cross-sectional design, researchers administered a self-developed questionnaire on prejudiced attitudes and intergroup contact to 215 students from Kehroor Pakka, Lodhran, and Dunya Pur, achieving a Cronbach’s alpha of 0.834 for reliability. Findings from 213 valid responses reveal that while students are generally tolerant, biases persist regarding gender, caste, and religion. Cooperative learning and culturally responsive teaching (CRT) improved intergroup relations, especially when teachers demonstrated fairness and respect. However, challenges such as teacher bias, favoritism, and limited intergroup interaction were reported. SPSS analysis showed that group learning effectively reduced conflicts, and students favored cross-caste friendships and discussions of relevant issues. The study recommends professional development and curriculum adjustments for preservice teachers to foster inclusive, no prejudicial classroom environments.

Published: November 2024

This research aims to investigate the effect of the incorporation of sewage sludge as an activator in the formation of fly ash-based geopolymers. The geopolymer paste is made up of 15% sewage sludge by weight, with the remainder consisting of fly ash. The blended mix is activated using a hydroxide solution containing 10% Na2O relative to the total base material. To assess the mechanical and microstructural characteristics of the resulting geopolymer paste, it is necessary to conduct compressive strength tests as well as FESEM, SEM, XRD, and TG/DTA analyses. To evaluate the workability of the designed geopolymer paste, an area factor test can be used here. GPP4, using sodium silicate, achieved the highest 3-day compressive strength (38.0 MPa) with a dense, amorphous structure and minimal mass loss. In contrast, GPP3 with sludge showed a porous texture and moderate strength. TGA supports the observation of GPP4's amorphous nature, aligning with the findings from XRD and FESEM analyses. Further, sorptivity tests revealed changes in pore size and volume based on the activator and fly ash type. GPP4 also exhibited a thermal conductivity of 2.44×10⁻⁴ cal/cm/°C/s, demonstrating sludge's potential as an economical alternative for geopolymer binders.

Published: November 2024

This work is devoted to typification, study of the compositional features and properties of hydrothermal zeolites of the Yagodninskoe deposit (Kamchatka Krai), formed over volcanic rocks. To carry out the research, X-ray phase and X-ray fluorescence analyses, optical and scanning electron microscopy were used; the specific surface area, pore size distribution, and cation exchange capacity of zeolites were determined. As a result of the research, 4 main types of rocks found at the deposit were identified: original unaltered perlites, zeolites themselves, zeolitized tuffs, and weakly zeolitized tuff breccias. The content of zeolite group minerals reaches 70%, and are mainly represented by clinoptilolite and to a lesser extent mordenite, stilbite and heulandite. Zeolites are of the alkaline type, the cation exchange capacity of which is 205.9 mEq/100 g. It was established that the formation of zeolites occurred mainly in perlites and tuff breccias. It is noted that the zeolites of the Yagodninskoye deposit have high quality raw materials and are the promising object for further development.

Assessment of the degree of tectonic fragmentation of the upper part of the lithosphere, according to the method of Yu.V. Nechaev [2010] is based on calculations of the specific length of lineaments. On the example of three different regions – the Northwestern Caucasus, the Voronezh anteclise, and the Malko-Petropavlovskaya zone of Kamchatka – we have tested the possibility of using other morphometric parameters: the specific lengths of “weak” zones, elongation lines and streams, as well as the Gaussian curvature of the relief. Their anomalies are confined to seismically active areas and areas of manifestation of hydrothermal-magmatic activity. It is shown that the most informative are 3D models of tectonic fragmentation, built taking into account the specific length of “weak” zones and watercourses.

Authors: Sah Sagnik , Putatunda Shyarshree , Majumder Rajib , Das Arpita
Published: November 2024

Lactic acid bacteria (LAB)-mediated fermentation of cereals is a preservation technique that enhances food flavor, nutrition, and safety. LAB naturally exists in cereals and plays a significant role in fermentation converting sugars into lactic acid and lowering the pH levels to create a distinctive sour taste and aroma. This process increases nutritional value and produces compounds like ethanol, acetic acid, and carbon dioxide, contributing to texture and appearance. LAB fermentation breaks down complex carbohydrates and proteins, improving digestibility and nutrient absorption. Common LAB-fermented cereal-based foods include sourdough bread, fermented cereal porridges, yogurt and kefir. Effective monitoring of volatile flavor compounds during fermentation is crucial for ensuring the quality, safety, and consumer acceptance of these foods.

Published: November 2024

The work considers the problem of creating a comfortable and safe space in residential environments within the limits of residential buildings.The requirements for the design of residential buildings and the improvement of the residential environment were analyzed and classified, taking into account the needs of all population groups. The main means of a comfortable, safe and barrierfree space in residential environments are defined.The consequences of the Russian-Ukrainian war and other reasons led to an increase in the total number of people with disabilities, whose share in the total population is actively increasing compared to the world average.Summarizing the above and analyzing groups of people who, for one reason or another, fall into the category of low-mobility population groups and accordingly need to create an accessible environment, we can say that the issue of accessibility in urban spaces concerns 90% of spaces. Therefore, in the context of world trends and principles of universal design, it is wrong to create any special conditions of accessibility for certain groups of people. On the contrary, it is necessary to create general conditions in the urban space that are as comfortable and safe as possible for as many people as possible.Identified needs and basic principles for creating a barrier-free, safe and comfortable space in residential environments, taking into account the needs of people with disabilities, which should have the following order of priorities: accessibility, safety, informativeness, comfort, universal (inclusive) design. The main requirements for residential environments were analyzed and systematized, taking into account the needs of the less mobile population groups. The main elements of barrier-free and universal (inclusive) design were considered and analyzed in order to determine the main calculation parameters in further research and projects of living spaces.

Authors: Zyhun Alina , Leshchenko Maryna , Avramenko Yurii , Kliepko Anastasiia , Pleshynets Artem
Published: November 2024

The monetary valuation of land within settlements is conducted with the aim of creating conditions for economic regulation of land relations during the transfer of ownership, mortgage, inheritance, purchase and sale of land plots, gifting, pricing, leasing, and determination of land tax rates.Starting from November 10, 2021, the monetary valuation of land is carried out in accordance with the "Methodology for Normative Monetary Valuation of Land Plots" approved by the Resolution of the Cabinet of Ministers of Ukraine № 1147 dated November 3, 2021. It provides the methodological principles for the normative monetary valuation of land plots, which is applied in cases determined by the Law of Ukraine "On Land Valuation". However, with the new methodology being implemented, a number of questions and clarifications to it have arisen, especially during the period of martial law. Since then, land plots of all categories and forms of ownership within the territory of a territorial community have become the object of normative monetary valuation. They are no longer divided into agricultural, non-agricultural, and lands of settlements.Among the areas of regulatory monetary valuation, the valuation of land in settlements has a special place. Despite the comparatively small percentage of land in settlements, it is exactly here where the main production and social potential of our country is concentrated. Most land and property transactions take place on land plots located in settlements. Therefore, the study of the regularities of monetary valuation of land in settlements is of great theoretical and practical importance.The new Methodology contains the same approaches to land valuation as the three previous ones. However, it contains a single formula for calculating the NMV. This formula combines all indicators and coefficients from the three previous methods.That is why it is an important and urgent issue to improve methodological approaches to the system of organization of normative monetary valuation of land in settlements.

Published: November 2024

The aim of the article is to conduct a study of the primary real estate market of Ukraine using geographic information technologies. The authors conducted a study of the primary real estate market in all regions of Ukraine from 2021 to 2024. The article collects and processes large amounts of statistical data on the cost and rental of housing. The authors propose ways to solve the problems associated with the constant processing and updating of data. Without the use of geographic information systems, it is impossible to collect and process large amounts of information in a short period of time. The relevance of the article lies in the use of geographic information systems in the study of large amounts of statistical information and the construction of cartograms on real estate in Ukraine. The result of the study is a reasonable conclusion about promising regions for investment in the primary real estate market. The speed of decision-making without the use of the created cartograms would be much slower, which in turn would have a negative impact on the investor. The practical significance of the results obtained by the authors includes the use of geographic information technologies in solving real estate investment problems. The proposed approaches can significantly speed up the process of selecting the most suitable region and property for investment.
TRANSFORMATION OF THE SYSTEM OF LOCAL EXECUTIVE GOVERNMENT AUTHORITIES IN THE CONTEXT OF DECENTRALIZATION POLICY
Authors: Baieva Iuliia
Published: November 2024

One of the components of the decentralization policy is the reform of the system of local executive authorities. The Road map of decentralization envisages the adoption, after the lifting of martial law, of the relevant amendments to the Constitution and the adoption of the law on prefects. The purpose of the research is to clarify the "path dependence" that was formed in the matter of the reorganization of local executive authorities, and at the same time to articulate problems that were not solved earlier and will need to be solved when developing new draft laws. The examination of draft amendments to the Constitution in 2015-2021 and the discussions surrounding them show that the integral elements of the "path dependence" of reforming local executive bodies in the context of decentralization reform have become the ideas of: significant limitation of the system of delegated powers; liquidation of local state administrations with simultaneous restoration of executive committees of regional and district councils; introduction of prefecture-type management structures; limiting the system of prefects' control over local self-government authorities by controlling the legality of the latter's activities; limiting the measures of such control by suspending the acts of local self-government authorities that do not comply with the Constitution and laws, with a simultaneous appeal to the court; limiting the term of office of prefects in order to prevent "corrupt growth" with local elites. Close to consensus is the situation regarding the status of prefects as civil servants. But some other provisions cause sharp contradictions. This is a question about the subject of the appointment of prefects, vertical subordination, etc. There are also contradictions in the choice of legality control models. Part of the contradictions is based on different interpretations of the ratio of such types of political-management relations as interaction, control, subordination, etc. In addition, despite the determination regarding the impossibility of constitutionally enshrining changes in the territorial organization of power during the period of martial law, this factor can hold back the transformation. In preparation for the introduction of prefecture-type authorities, the government declares its intention without amending the Constitution, that is, without canceling the system of delegated powers, to amend the Law On local state administrations, giving the latter powers of control and supervision over the legality of the activities of local self-governance and creating a vertical of control authorities. But the parliamentary Main Legal Department believes that this cannot be done without changes to the Constitution. Moreover, it is currently unclear how this process correlates with the creation of the administrative justice system.
ETHNOPOLITICAL ASPECT OF LOCAL SELF-GOVERNMENT REFORM IN UKRAINE
Authors: Pereguda Yevhen
Published: November 2024

The study examines the ethno-national aspects of the implementation administrative-territorial reform and the decentralization process in Ukraine. The essence of ethno-national policy, its orientation and purpose are defined. The legal framework was analyzed in the context of the implementation of the state ethno-national policy in the process of forming united territorial communities in the places of compact residence of national minorities. When developing and implementing ethno-national policy not only at the state, but also at the regional and local levels, it is necessary to take into account historical, ethnic, geographical, economic, national-cultural, religious, demographic, migration features, and in some cases, international relations and connections with neighboring states. The latter can range from constructive transboundary cooperation to the threat of escalation of separatism and irredentism. All this significantly affects the practical activities of public authorities, creates a real opportunity for national minorities to realize their rights in the economic, educational, cultural space and take an active part in state-building processes, while avoiding destructive ethno-political processes and phenomena, which is a condition for the harmonization of inter-ethnic relations in the state. For a multinational state, the main task of ethno-national policy is to maintain a balance of the interests of national and ethnic groups with the interests of the state and every citizen. Ethno-national policy, as a component of internal policy, ensures the country's stability and prevents the emergence of manifestations of nationalism and separatism. In Ukraine, there are the main factors of the development of regionalism, which have their own ethno-political context. At the local and regional levels, there are ideas of uniqueness (community, district, region), the desire to preserve historical and cultural heritage. Among regional communities, self-awareness of regional belonging is clearly expressed. Against this background, the current ethno-political legislation contains problematic issues that need to be resolved. Yes, the rights of national minorities are not defined as individual or collective, and hence it is not clear whether a united territorial community can act as a subject of ethno-political relations? The term "indigenous peoples" is mentioned in the legislation. At the same time, it is only about the rights of "persons belonging to national minorities". Also, in the conditions of decentralization, the problem of training managerial and other personnel for regional local self-government bodies from the circle of national minorities emerges acutely.

Published: November 2024

Faced with technological change, which has accelerated since the early 2000s, and a world that is increasingly unstable, companies are looking for new ways of organizing their activities to make themselves more agile. At the same time, attitudes to work and career paths are changing: people are looking for a better work-life balance and meaningful work. However, their careers are increasingly fragmented. In addition, the fight against climate change imposes the transformation of production systems. These new trends are leading to the emergence of new ways of managing work activities, which will undoubtedly have an impact on OSH.

This paper summarizes the foresight study conducted by the Research Institute for Occupational Health and Safety in France (INRS) on the evolution of management methods and their possible consequences in terms of health and safety at work. With a multidisciplinary team, the Institute’s Watch and Foresight unit first explored the main factors of change underway in order to imagine during the second phase company profiles in 2040 based on the design fiction method. The profiles of these fictitious companies and their employees were then analysed by occupational health and safety experts to identify the main challenges and potential opportunities that could emerge in the domain of occupational risk prevention.

Published: November 2024

This article sets out to report our first-hand experience with using focus groups as a method of data collection in higher education research. We were interested in shedding light on how university lecturers coped with remote teaching during the Covid pandemic and how the unusual circumstances affected their teaching. The analysis of the resulting data is still ongoing. In this study, we summarise our experiences of using the focus group methodology in our research. By discussing and evaluating our research experiences, we aim to demonstrate the usability and the potential risks of the Focus Group Discussion (FGD) in a higher education context by identifying further areas of application, such as for supporting the development of the education system. We argue that the main characteristic of FGD is its interactive nature, and we back this claim by providing a detailed presentation of the focus group methodology, as well as by describing and analysing the experiences of group discussions conducted with the involvement of university lecturers. Due to their interactive nature, focus group discussions are particularly suitable for research on educational methodology, specifically within the training system for public officials operated by the Ludovika University of Public Service (LUPS) in Budapest, Hungary since 2013. The focus group research method can be used either as a tool for quality assurance or as a tool for assessing training needs. Our study is highly relevant for those who are planning to conduct focus group research in a higher education context or in related fields such as adult education programmes, by providing practical recommendations.
Coping strategies of tertiary athletes in Singapore : The influence of achievement goals, motivational climate and a brief relaxation intervention
Authors:   , Shermaine Shuqi Lou
Published: November 2024

As the sports industry thrives with local athletes gaining more international recognition, athletes face increasing pressure to perform. This pressure requires effective coping with stress or defeat. Moreover, effectiveness of coping strategies differs across unique individuals. Hence, examining disposition and situational factors could explain effective coping. Cluster analysis revealed in a mastery climate, athletes with high mastery and low performance goals used the most adaptive coping strategies whilst athletes with high mastery and performance goals used the least maladaptive coping strategies. Follow-up interviews found athletes to place high expectations on themselves and think negatively. Athletes largely responded with both positive and negative mental skills. The efficacy of a brief relaxation training session on reducing anxiety in a mastery and performance climate for golf-putting was determined through questionnaires, brainwave and qualitative date. There was no significant difference between both climates, but the intervention helped improve post-performance scores. Future studies could further explore how brief relaxation techniques can impact sport performance.

Hyperparameter Tuning of EfficientNet Method for Optimization of Malaria Detection System Based on Red Blood Cell Image
Authors: Pamungkas Yuri , Eljatin Dwinka Syafira
Published: November 2024

Nowadays, malaria has become an infectious disease with a high mortality rate. One way to detect malaria is through microscopic examination of blood preparations, which is done by experts and often takes a long time. With the development of deep learning technology, the observation of blood cell images infected with malaria can be more easily done. Therefore, this study proposes a red blood cell image-based malaria detection system using the EfficientNet method with hyperparameter tuning. There are three parameters which are learning rate, activation function, and optimiser. The learning rate used is 0.01 and 0.001, while the activation functions used are ReLU and Tanh. In addition, the optimisers used include Adam, SGD, and RMSProp. In the implementation, the cell image dataset from the NIH repository was pre-processed such as resizing, rotating, filtering, and data augmentation. Then the data is trained and tested on several EfficientNet models (B0, B1, B3, B5, and B7) and their performance values are compared. Based on the test results, EfficientNet-B5 and B7 models showed the best performance compared to other EfficientNet models. The most optimal system test results are when the EfficientNet B5 model is used with a learning rate of 0.001, ReLU activation function, and Adam optimiser, with values of 97.69% (accuracy), 98.36% (precision), and 97.03% (recall). This research has proven that proper model selection and hyperparameter tuning can maximise the performance of cell image-based malaria detection system. The development of this EfficientNet-based diagnostic method is more sensitive and specific in malaria detection using RBCs.

Potato production in Indonesia has grown very rapidly, making Indonesia the largest potato producer in Southeast Asia. However, there are challenges for farmers in growing potatoes. Such as treating potatoes for various diseases. 2 diseases will occur in potato plants if not treated quickly, namely early blight disease caused by the fungus Alternaria solani and late blight disease caused by the microorganism Phytophthora infestans. The project "Potato Plant Leaf Disease Detector (MR-PoLod)" aims to design an android application that can classify leaves on potato plants into 3 classifications, namely healthy, early, and late blight disease. This application uses the CNN (Convolutional Neural Network) Machine Learning Algorithm because currently, CNN is recognized as the most efficient and effective model in pattern and image recognition tasks. This application uses the Python programming language which is rich in library and framework availability so that it can meet the needs of machine learning and image classification tasks. The total data used for training data, data validation and data testing is 3165 images. With each division of the data process on the training data of 70%, validation of 15% testing of 15% to test the effectiveness of the model that has been created. The performance of MR-PoLod for each class, obtained a precision value, recall, and f1-score of 0.99. Likewise, the accuracy value achieved by the model is 0.99 or 99%. Thus, the expected application can facilitate farmers in classifying diseases on potato plant leaves.

The increasing prevalence of malware poses significant risks, including data loss and unauthorized access. These threats manifest in various forms, such as viruses, Trojans, worms, and ransomware. Each continually evolves to exploit system vulnerabilities. Ransomware has seen a particularly rapid increase, as evidenced by the devastating WannaCry attack of 2017 which crippled critical infrastructure and caused immense economic damage. Due to their heavy reliance on signature-based techniques, traditional anti-malware solutions struggle to keep pace with malware's evolving nature. However, these techniques face limitations, as even slight code modifications can allow malware to evade detection. Consequently, this highlights weaknesses in current cybersecurity defenses and underscores the need for more sophisticated detection methods. To address these challenges, this study proposes an enhanced malware detection approach utilizing Extreme Gradient Boosting (XGBoost) in conjunction with Chi-Squared Feature Selection. The research applied XGBoost to a malware dataset and implemented preprocessing steps such as class balancing and feature scaling. Furthermore, the incorporation of Chi-Squared Feature Selection improved the model's accuracy from 99.1% to 99.2% and reduced testing time by 89.28%, demonstrating its efficacy and efficiency. These results confirm that prioritizing relevant features enhances both the accuracy and computational speed of the model. Ultimately, combining feature selection with machine learning techniques proves effective in addressing modern malware detection challenges, not only enhancing accuracy but also expediting processing times.

В сучасних реаліях економіки України діяльність суб’єктів бізнесу супроводжується різного роду ризиками. Це може призвести до неотримання прибутку, втрати грошових коштів або навіть до збитку. У зв’язку з цим виникає потреба у прогнозуванні таких показників діяльності суб’єктів бізнесу, які покладено в основу вибору ефективних методів зниження рівня фінансового ризику. Володіння такою інформацією дозволить суб’єкту бізнесу вчасно вжити заходів, щоб покращити його фінансовий стан та запобігти банкрутству. Тому, щоб уникнути цього, актуальним завданням є визначення ринкової вартості суб’єкта бізнесу на даний момент, а також прогнозування величини на наступний період. Для цього використовують прогнозні значення чистого фінансового результату (збитку) та вартості чистих активів, що отримується як методами аналітичного, так і механічного вирівнювання (метод ковзної середньої). При прогнозуванні за допомогою рядів динаміки слід більше уваги приділяти кінцевим значенням рядів. Саме це досягається, застосовуючи метод ковзної середньої. Оскільки використання точкових прогнозів не позбавлене недоліків, то для отримання більш точних результатів у практичних застосуваннях поряд із точковою оцінкою слід вказати ще й інтервальну для наперед заданого рівня значущості, що те саме побудувати довірчий інтервал для індивідуальних значень прогнозу. Зокрема, нами побудовано довірчі інтервали як для вартості чистих активів, так і для чистого фінансового результату (збитку), використовуючи метод середніх (середній абсолютний приріст). Враховуючи значення як точкових прогнозів, так і значення меж довірчого інтервалу для прогнозних значень вартості чистих активів та чистого фінансового результату, розраховано дев’ять значень вартості суб’єкта бізнесу і вказано межі, в яких вони знаходяться.

Стаття присвячена актуальним питанням визначення сутності та особливостей формування конкурентних стратегій на підприємствах. Встановлено, що одним із ключових напрямків стратегічного планування є конкурентна стратегія підприємства, яка генерує конкурентні переваги та передбачає перспективу ефективного функціонування та розвитку. Досліджено критерії формування конкурентних переваг підприємства. В Україні поступово створюються нові умови для діяльності підприємств, за яких особливого значення набувають стратегічний підхід, концепція стратегічного управління та розробка стратегії розвитку. Однак більшість підприємств мають низький рівень розвитку цих складників, особливо в сфері маркетингових стратегій. Незважаючи на це, реалізація маркетингових стратегій є ефективним способом забезпечення належного рівня конкурентоспроможності та успішного функціонування підприємства в сучасних умовах бізнесу. Питання розробки маркетингових стратегій підвищення конкурентоспроможності підприємства є актуальними і відіграють важливу роль у виробничих процесах, формуванні збутової політики, організації збутової діяльності та розвитку системи маркетингового менеджменту. У статті доведено, що врахування та дотримання принципів розробки стратегії дає змогу створити ефективний засіб досягнення цілей підприємства, забезпечуючи високу конкурентоспроможність і гнучкість. Обґрунтовано особливості формування конкурентної стратегії підприємства, визначено концептуальні положення цього процесу. У статті також обґрунтовано теоретико-методологічні підходи до вибору конкурентних стратегій підприємств та представлено маркетинговий напрям їх удосконалення. Подано схему поетапного формування маркетингової стратегії підприємства на основі структурно-логічної схеми та оцінки конкурентних позицій підприємства.

Позитивна динаміка розвитку біоенергетики зумовлює необхідність у розробці структурованої теоретичної бази для відображення біоенергетичних активів в обліку та інтегрованій звітності аграрних підприємств. Комплексний підхід до формування концептуальних засад біоенергетичних активів, починаючи від вирощування енергетичних культур до виробництва біопалива, сприятиме створенню правильної методики обліку стратегічно важливих об’єктів енергетики. Метою дослідження є визначення складу і структури біоенергетичних активів для відображення в обліково-інформаційній системі аграрних підприємств. До складу біоенергетичних активів включено: енергетичні рослини, біомасу, біопаливо. Енергетичні рослини класифіковано за такими ознаками: видом (енергетичні та сільськогосподарські культури), терміном експлуатації (багаторічні та однорічні), походженням (наземні та водорості), складом (олійні, лігноцелюлозні та цукровмісні). Визначено, що перевагами енергетичних рослин є: альтернатива викопному паливу, позитивний вплив на грунт та клімат, невибагливість до природних умов. Біомасу для облікових потреб розділено на чотири складові: рослинного походження (деревна та трав’яна біомаса); тваринного походження; мікроводорості; промислові і побутові відходи. Біопаливо як біоенергетичний актив структуровано за агрегатним станом на: тверде (паливні дрова, деревні гранули, пелети, біовугілля), рідке (біодизель, біоетанол, біометанол, біопропанол, біобутанол, біомазут), газоподібне (біогаз, біометан, біоводень). Запропонована структура біоенергетичних активів дає можливість створити інформаційну базу для коректного відображення їх на рахунках обліку аграрних підприємств. Подальші дослідження будуть спрямовані на управління собівартістю біоенергетичних активів як важливого макроекономічного інструменту впливу на енергетику та клімат.
ОРГАНІЗАЦІЯ ІННОВАЦІЙНОЇ ДІЯЛЬНОСТІ ПІДПРИЄМСТВ В УМОВАХ ВОЄННОГО СТАНУ

Важливим вектором функціонування вітчизняних суб’єктів господарювання повинна стати активізація інноваційної діяльності як чинник досягнення успіху на ринку, а також як запорука виживання в умовах загострення конкурентної боротьби та за умов воєнного стану. Незадовільний стан інноваційної активності переважної більшості підприємств України пояснюється обмеженістю фінансових ресурсів, спрямованих до інноваційної сфери, підвищеним ризиком будь-якого інвестування, відсутністю у країні дієвої політики, що стимулює нововведення. Забезпечення розвитку промислових інновацій потребує створення та функціонування відповідних інституцій, які впливатимуть на інноваційну діяльність у промисловому секторі та сприятимуть впровадженню та поширенню інновацій. Тому формування та розвиток національної інноваційної системи є надзвичайно важливим аспектом промислово-інноваційного розвитку та неодмінною логікою реалізації національної інноваційної політики. Активізація інноваційної діяльності можлива тільки на основі розвиненої системи фінансування, що покликана забезпечувати вирішення таких найголовніших завдань: створення необхідних передумов для швидкого та ефективного впровадження нововведень у всіх ланках народно-господарського комплексу країни, забезпечення її структурно-технологічної перебудови; збереження і розвиток стратегічного науково-технологічного потенціалу в пріоритетних напрямах розвитку; створення необхідних матеріальних умов для збереження кадрового потенціалу науки і техніки, запобігання його відтоку за кордон. Для вдосконалення стимулювання інноваційної діяльності в Україні потрібен новий комплексний механізм стимулювання всього інноваційного процесу – від фундаментальних досліджень до впровадження розробок у виробництво. Створення такого механізму є доцільним не тільки на державному, а й на регіональному рівні. У перспективі основним джерелом фінансування інноваційної діяльності мають стати приватні фінансові ресурси вітчизняних та іноземних інвесторів за законодавчої підтримки інноваційної сфери з боку держави.
