The state and prospects of the development of the Mekong problem

The problem of water resources in international relations is one of the most discussed since the second half of the last century. Since the mid-1960s, water consumption in the world has more than doubled and continues to grow. This makes fresh water one of the most important factors influencing the international and domestic political situation. In the Greater Mekong subregion, this problem is already one of the main ones. The main reasons for this are rapid economic and demographic growth, as well as changing climatic conditions. The situation is complicated by the geopolitical significance of the region, which makes it a place of struggle for influence from global and regional players. The paper notes the role of the Mekong River in the economy of the countries of the subregion, because the contradictions between them are the main cause of international processes related to the river. The author also noted the influence on the situation from the leading world powers and the possibility of smoothing the problem from Russia.

Privacy-Preserving Federated Learning of Remote Sensing Image Classification With Dishonest Majority

The classification of remote sensing images can give valuable data for various practical applications for smart cities, including urban planning, construction, and water resource management. The federated learning (FL) solution is often adopted to resolve the problems of limited resources and the confidentiality of data in remote sensing image classification. Privacy-preserving federated learning (PPFL) is a state-of-art FL scheme tailored for the privacy-constrained situation. It is required to address safeguarding data privacy and optimizing model accuracy effectively. However, existing PPFL methods usually suffer from model poisoning attacks, especially in the case of dishonest-majority scenarios. To address this challenge, in this work, we propose a blockchain-empowered PPFL for remote sensing image classification framework with the poisonous dishonest majority, which is able to defend against encrypted model poisoning attacks without compromising users' privacy. Specifically, we first propose the method of proof of accuracy (PoA) aiming to evaluate the encrypted models in an authentic way. Then, we design the secure aggregation framework using PoA, which can achieve robustness in a majority proportion of adversary settings. The experimental results show that our scheme can reach 92.5%, 90.61%, 87.48%, and 81.84% accuracy when the attacker accounts for 20%, 40%, 60%, and 80%, respectively. This is consistent with the FedAvg accuracy when only benign clients own the corresponding proportion of data. The experiment results demonstrate the proposed scheme's superiority in defending against model poisoning attacks.

СОЦИАЛЬНЫЕ ФАКТОРЫ СМЕРТНОСТИ МУЖСКОГО НАСЕЛЕНИЯ: РОССИЯ НА МИРОВОМ ФОНЕ

The subject of the study is to assess the mortality rate of the male population in Russia. The purpose of the study is, based on current statistics, to identify the country’s global position in terms of male mortality and the nature of the impact of social fac- tors on it. The relevance of assessing the mortality rate of Russian men against a global background is determined by the urgent need to attract public attention to this issue, which has an impact on the problem of limited labor resources and conscription potential of the country, on the growth of social production, and provokes many social problems associated with the loss of a breadwinner. The scientific novelty is determined by an integrated approach to the study of the factors of high mortality among men while simultaneously identifying the country’s position in global rankings of the state of human potential. The paper used general logical, analytical, statistical and cartographic methods. An attempt has been made to comprehensively consider the causes of high male mortality in Russia. The authors focused on identifying the social factors of this phenomenon. Research results: it was found that the country has taken a leading position in the world in terms of the gap in life expectancy between men and women, and the specific values of male mortality (per 1000 men of all ages) raise the country to the ninth place in the world. Almost 9% of Russian men do not live to be 40, and 35% do not live to be 60. The high mortality rate of the male population of Russia is a consequence of the mutual influence of many factors. However gender differences in mortality from external causes are especially large (five times). The authors conclude that Russian men experience double pressure from social factors of early mortality - complex economic reality and traditional society with its idea of “post-Soviet masculinity”, in the construction of which alcohol, smoking, and neglect of one’s own health played a major role. One of the main tasks today is to turn our attention to the problems of adult men,and to begin to perceive them as a vulnerable social group that also requires support from the state.

The Role of Enterprises of Village (BUMG) In Improving The Economy of The Community of Keureusek Village

The village is the smallest area of ​​the State of Indonesia that is closest to the community and has territorial boundaries so that it can be prospered and empowered. Villages have a lot of potential not only in terms of population, but also the availability of abundant natural resources. If these two potentials can be managed optimally, it will provide welfare for the villagers. However, it is realized that so far development at the village level is caused, among others, not only because of the problem of poor-quality human resources but also due to financial problems. One of the efforts that can be done is to encourage the movement of the village economy through village entrepreneurship, where village entrepreneurship is a strategy in developing and empowering villages. This village income source is a source of village income received from efforts carried out by the village government together with the Village Consultative Body (BPD) and the existing village community cannot be maximized to increase village income, especially because the village government controls village assistance from the government.

ІНФОРМАЦІЙНЕ ПІДҐРУНТЯ ЗАБЕЗПЕЧЕННЯ ІНВЕСТИЦІЙНОЇ БЕЗПЕКИ МАШИНОБУДІВНИХ ПІДПРИЄМСТВ

In the conditions of the implementation of the fourth industrial revolution, the importance of effective engineering activities is growing, which should be aimed at creating high-tech means of labor, based on the need to more fully satisfy the needs of consumers in the face of growing limitations in natural resources. The purpose of the study was to carry out a thorough analysis of the main parameters of the investment activity of machine-building enterprises in order to form an information base for ensuring their investment security. In order to create an information basis for ensuring the investment security of machine-building enterprises, the following methods were used: induction and deduction, comparison and systematization – when studying the differences in the investment activity of machine-building enterprises according to the main types of economic activity; synthesis and analysis – to consider the dynamics of the main indicators characterizing the investment activity of enterprises and the structure of capital investment sources in 2010–2021; morphological analysis – to identify the impact of the main factors limiting the investment activity of machine-building enterprises; graphic – for visual representation of theoretical and methodical material; abstract-logical – for theoretical generalizations and research conclusions. The current conditions of the economic activity of Ukrainian enterprises are burdened not only by the results of previously implemented privatization processes and transformations of the national economy, but also by the modern influence of military actions and the latest pandemic, which in general both limits their competitive position on the domestic and foreign markets and actualizes the problem of ensuring investment security. Solving the complex problems of limited investment resources and effective investing in conditions of high investment risks requires, as a priority, the creation of an informational basis for the further development of adequate and effective measures on the part of security entities. It is proposed to create such a foundation not only in relation to the investment activity of a certain enterprise, but based on the general situation in mechanical engineering, that is, a holistic idea of the content of all related processes. The basis of the study is the consideration of the dynamics of capital investments in terms of the main types of economic activity of mechanical engineering, the scale of operation of enterprises, sources of investments and financial results. The result was a critical assessment with the identification of the level of influence of key factors as objects of attention of security subjects for the development of adequate and effective measures.

В УКРАЇНІ ВИДАНО ПЕРШИЙ НАВЧАЛЬНИЙ ПОСІБНИК З ГІДРОГРАФІЇ ТА ВОДНИХ РЕСУРСІВ ЄВРОПИ (2023 Р.)

The article presents and analyzes the training manual “Hydrography and Water Resources of Europe”, published by the professor Taras Shevchenko National University of Kyiv V.K. Khilchevskyi in 2023. The first training manual k published in Ukraine on this topic briefly outlines the basics of EU water policy, characterizes rivers, lakes and reservoirs on a regional basis (UN geoscheme – Northern, Western, Southern and Eastern Europe), as well as seas washing the shores of Europe. The problems of global water resources are considered, the ranking of European countries in terms of renewable water resources and the index of water resource exploitation is given. In the context of all directions, questions on Ukraine were considered. In Europe, hydrographic surveys are of great importance for water management. In particular, according to the European Union Water Framework Directive (WFD) adopted in 2000, the hydrographic zoning of countries’ territories is an important step for creating river basin management plans in the implementation of water policy. This approach is used by both EU member states and other European countries that have taken the provisions of the EU WFD as the basis for their activities. Water resources in a broad sense are all the waters of the hydrosphere, including the waters of the oceans and seas, rivers and lakes, groundwater, and glaciers. In practice, both in Europe and in many countries of the world, the concept of “water resources” is interpreted in a narrower sense – these are fresh surface and groundwater that are in water bodies and are used or can be used by humans. Water resources are managed according to the basin principle, but water resources are taken into account within individual countries. For. structuring the presentation of the material in this tutorial, the division of Europe into subregions according to the UN geoscheme was chosen, according to which 4 subregions are distinguished: Northern Europe; Western Europe; Southern Europe; Eastern Europe – a total of 44 countries whose capitals are located in this part of the world. But geopolitically, Europe includes 50 sovereign states. Their territory is within the framework of the general definition of Europe, they have membership in international European organizations. The content of the manual is structured into four parts: I – Physical-geographical and economic-geographical characteristics of Europe; II – EU Environmental and Water Policy; ІІІ – Hydrography; IV – Water resources. The training manual is intended for students enrolled in the educational program “Management and Ecology of Water Resources”, specialty 103 “Earth Sciences”. It can also be useful for students of other educational programs of specialties 103 “Earth Sciences” and 106 “Geography”, which study water resources.

SYSTEMIC RELATIONSHIPS OF DEBT SECURITY IN THE CONDITIONS OF FINANCIAL GLOBALIZATION

The process of globalization exerts a double influence on the world financial system, causing simultaneous development and emergence of potential threats to the financial security of the country. In the conditions of today's financial globalization and the spread of globalization imbalances, there was an aggravation of problems with servicing and repayment of accumulated debt, which caused significant deformation processes in the system of public finances of Ukraine. Therefore, it is necessary to study in more detail the factors influencing the level of debt security and its interdependence with other indicators of economic security. The purpose of the work is to investigate and analyze the interrelationships of debt security and evaluate its level using retrospective analysis and taking into account the impact of the process of financial globalization. After analyzing the values of economic security indicators, we can come to the conclusion that the highest rate of decline in the level of financial security occurred in 2015 for 14 years. p. to the level of 36% among other indicators of economic security. It was established that this situation is caused by a decrease in the level of income from the main budget-forming taxes due to increased fiscal pressure on the economy, a sharp devaluation of the national currency, a fairly significant increase in the amount of state and state-guaranteed debt with an increase in the probability of default, illiquidity and insolvency of financial institutions, a decrease in the amount of the resource base banks and problems with capitalization. All this is the basis for the critical state of almost all indicators of financial security. An analysis of the current state of debt security indicators was carried out. An assessment of correlations between the integral indicator of the level of debt security and other indicators of economic security is given. Factors and interrelationships influencing the level of debt security are determined. The linear dependence and the most significant influence on the critical level of debt security had the same critical levels of banking and budgetary security. The need for further improvement of methodological approaches to determining the level of debt security is argued, taking into account globalization processes and factors of endogenous and exogenous influence, which include the size of the shadow sector of the economy, banking and currency instability, inflationary processes and other factors that are the basis for the formation of sustainable debt security. The scientific novelty of the research is based on the results of the analytical assessment of the interdependence of the level of debt security, the levers, methods and tools of state regulation of threats and risks were formed, strategic monitoring, forecasting and implementation of preventive measures were carried out in order to ensure the appropriate level of economic and financial security. The practical significance of the obtained results is that the provisions on improving the methodological basis for assessing the level of debt security of the country, taking into account the interdependence of debt security and other indicators of economic security, have been confirmed. These results have an applied value for state administration bodies in the process of drafting programmatic and strategic documentation in order to ensure the appropriate level of economic security of the country.

Внедрение новых технологий в процесс хранения нефтепродуктов – объективная необходимость экономической эффективности их использования и охраны окружающей среды

In the article theoretical and practical aspects of implementation of new technologies in the field of the energy complex on the example of assessing the effect of reducing fuel vapor emissions on the basis of two specialized oil terminal in the Russian Far East are presented. Nowadays insufficient attention is paid to the problem of resource saving, recycling and use of petroleum products. Meanwhile, according to the scientific publications, the ratio of growth in production and consumption of petroleum products is predicted. In this connection, a significant expansion of the oil storage will be required and, as a result, solving the problems of increasing the economic efficiency and environmental safety of storing oil products in various ways, including the method of recovering. There are a diffusion of petroleum and atmosphere, so as a result we have petroleum losses and the negative impact on the environment. The Khabarovsk territory is a main region of the Russian Far East, where the industrial production of petroleum products is carried out. The main facilities for storage and transshipment of fuel are also located here. So, for our region, the issue of reducing the loss of oil products during transshipment and storage is particularly acute. The problem of reducing the loss of petroleum products during transshipment and storage for our region is particularly acute. The results of the research of modern methods to reduce the loss of petroleum products on the example of the introduction of fuel vapor recovery units in the production process of oil terminal can be applied in development and implementation of plans for the construction of new oil depots and modernization of existing not only in the Khabarovsk city but throughout the Russian Federation.

ДИНАМИКА СИСТЕМЫ МЕСТНОГО САМОУПРАВЛЕНИЯ В РЕГИОНАХ ЮГО-ЗАПАДНОЙ СИБИРИ: ТЕРРИТОРИАЛЬНО-ОРГАНИЗАЦИОННЫЙ АСПЕКТ

The development of the institution of self-government in Russia in previous decades faced numerous systemic problems of resource, organizational and social nature, which led to the dependence of it on the state power. Further integration into the unified system of power in the Russian Federation was secured by the constitutional amendments of 2020. However, at the regional level, particularly in the regions of Southwestern Siberia, the process of centralization began earlier, starting as early as the mid-2000s. Indicators of this trend were the abandonment of the election of the majority of local government officials, the merger of municipalities, and, more recently, the transition to municipal districts.

Smart structural control and analysis of edge computing power in AI aquaculture

Traditional aquaculture fish ponds are located outside people’s living areas. Collecting water environment data and uploading them to the cloud server for processing requires high network resources. Using edge computing power to process local data can solve network resource problems while achieving intelligent coordination between devices. Using the Raspberry Pi as an edge computing device in the local space, the system is explained from the three main aspects of the perception layer, the transmission layer and the application layer. The goal of real-time and refined resource management is achieved through intelligent algorithms, so that the data is respectable and credible. Further explore the feasibility of intelligent collaboration in aquaculture. Practice shows that the system runs stably on the physical model and has the characteristics of fast response in perception and control.

Prediction and Comparison of Rainfall-Runoff Using Mathematical Model

The Runoff assessment is a crucial parameter in understanding the urban flooding scenario. This estimation becomes the deciding factor because of the uneven distribution of rainfall. Physics-based models for simulation of Runoff from catchments are composite models based on learning algorithms. The application of models to water resource problems is complex due to the incredible spatial variability of the characteristics of watershed and precipitation forms — the pattern-learning algorithms. Fuzzy-based algorithms, Artificial Neural Networks (ANNs), etc., have gained wide recognition in simulating the Rainfall-Runoff (RR), producing a comparable accuracy. In the present study, RR modeling is carried out targeting the application and estimation of Runoff using mathematical modeling. The investigations were carried out for the Malkajgiri catchment adopting 16 years of daily data from 2005 to 2021. The statistical learning theory-based pattern-learning algorithm is further utilized to evaluate the value of Runoff for the year 2021. The results were found to have fair accordance with the analytical outcomes.

TENEURS EN NITRATES DANS LES AQUIFERES DISCONTINUS DU SOCLE DU DAMAGARAM MOUNIO (EST DU NIGER)

The basement of Damagaram Mounio, study area, outcrops in the eastern part of the Zinder region. It is a very populated area and where the problem of water resources is acute. In addition to the low availability of this water resource, its quality remains questionable in several areas. Thus, the contents of certain chemical parameters, including nitrates in particular, greatly exceed the drinking water standards for human consumption, hence the present study, which has as its main objective, the determination of the percentages of boreholes whose the waters have nitrate levels above the WHOstandard. The methodological approach based on the sampling of hydraulic structures capturing the aquifers of the basement, the analysis of the physicochemical and isotopic parameters of the waters of several boreholes, the determination of the characteristics of the nitrates, made it possible to lead to several interesting results.Thus, the nitrate contents of the waters of the Damagaram Mounio basement aquifers vary from 0.22 to 313.3 mg/L, with an average of 72.23 mg/L, and a standard deviation of 62.23. This study made it possible to show that 32% of the modern structures sampled have nitrate levels above the admissible limit value for drinking water, set at 50 mg/L, according to the standards of the World Health Organization (WHO) these waters are unfit for human consumption. The spatial distribution of nitrate levels in groundwater in the area showed that these are more accentuated between the towns of Damagaram Takaya and Birni Kazoe, which are characterized by values ​​above 100 mg/l. The relation between nitrate contents and water electrical conductivity values ​​showed that the mineralization of groundwater in the area is controlled by nitrate ions. Furthermore, the isotopic levels of Nitrogen 15 (15N), obtained in the waters of the area, vary from 0 to 7.2, thus showing that these nitrates could come from the nature of the soil (quagmire around water points) and chemical fertilizers (ureas and fertilizers used in the study area).

School as a learning organization through strengthened self-efficacy and empowered preschool teachers

A school as a learning organisation (LO) is indispensable today. However, the limitations of schools in human resources (teacher) problems, infrastructure facilities and funds become real obstacles. This research is carried out to find a LO model based on strengthening self-efficacy and empowering teachers. The research was conducted with a quantitative approach, a causal associative type with survey methods involving 237 pre-elementary teachers. Samples are determined by using a simple random sampling technique. Data analysis uses regression analysis to test aspects of relationships and direct influence between independent and dependent variables. The main result of this research is a positive causality relationship, and if the self-efficacy and empowerment of teachers are high, then the LO will be increased significantly. Strengthening the LO through self-efficacy and teacher empowerment is very important because it can improve the quality of graduates. Keywords: : Learning organization, strengthened self-efficacy, empowered teachers, pre-elementary school, school management

People and Talent-Based Circular Economy

Future organizations will need help addressing the shortage of skilled resources. While a progressive education system would bridge the gap for some of these resource challenges, other challenges that we could encounter would be associated with the liberalization of workforces in the Gig Economy. The overall objective is not for the race towards being the biggest or best but for working in a cohesive ecosystem that would meet the growing business needs. The circular economy is receiving worldwide increased attention to accelerate economic growth from the optimal consumption of resources. Cities and urban regions are a growing source of resource consumption and are increasingly recognized by national and regional governments as an arena to mitigate resource problems associated with urbanization. This research paper aims to prescribe the approaches that will help organizations adopt a Cyclic Economy to address the growing demand for skilled resources in the years ahead, thus capturing more value from resources.

Managing Cost and Schedule Evaluation of a Construction Project via BIM Technology and Experts’ Points of View

This research examines the beneficial contributions of project management to manage the cost and schedule of construction projects providing higher accuracy and reliability levels. The study depended on two main research approaches quantitative (online survey questionnaires) and qualitative (interviews) research techniques. The questionnaires and interviews aim to predict the importance of BIM technology in managing the cost and schedule of construction projects. Also, a third research method is employed, which represents a case study of a building, to make a comparison in terms of accuracy, effort, and budget of quantity take-off between manual (hand calculations) and numerical (REVIT Software estimations) approaches. The results revealed that adopting project management principles could significantly cut considerable budget, time, and effort to execute and complete construction projects. Also, project management is vital to prevent any financial losses or resource problems resulting from cost overruns or delays. Moreover, the results indicated that using modern project management techniques (including BIM technology and REVIT Software) could support engineers and project managers calculate the cost and schedule of their projects more accurately, avoiding errors. Besides, the results confirmed that using the REVIT software could aid project managers and civil engineers in evaluating the budget and time required to accomplish the construction project with less effort, time, and cost and provide a lower number of human errors compared with hand calculations. It was found that the manual and numerical results are greatly approximate to each other. Still, the results of the REVIT software offered more significant precision because of the accuracy in the modeling and the few engineers’ mistakes in calculating quantities manually.
