Borrowing and Historical Evolution of Tales and Fables about the Wonderful Hero in the Folklore Traditions of Vietnamese Peoples

The article is dedicated to the analysis of the fairy-tale plot about a wonderful child in the form of a theriomorphic or phytomorphic creature in the folklore of the Viet, Hmong, Cham, Sedang, Stieng, Thai ethnic groups inhabiting the territory of modern Vietnam, as well as in folklore of other peoples of the Far East. Through the study, the methods of structural, typological and comparative analysis of plots, motives and heroes of folklore narratives are used. Hopefully, this approach will help to make assumptions about the ways of borrowing and transforming significant elements of fairy tales in the region. The article examines three Vietnamese fairy-tale texts – “Man Round as a Coconut”, “Magic Turtle” and “Little Turtle”, each of which is compared with both geographically close and distant versions of the narratives.

An Adaptive Kriging-Based Fourth-Moment Reliability Analysis Method for Engineering Structures

The fourth-moment method can accurately perform a reliability analysis when it is challenging to determine the distribution of the random variable due to limited available samples. This method only utilizes the first four moments of the random variable and constructs the fourth-moment reliability index. However, it cannot be applied in engineering cases where the state function cannot be expressed explicitly, as it becomes difficult to establish a correlation between the first four moments of the random variable and the state function. Simplifying the state function forcefully may result in significant reliability prediction errors. To address this limitation, this study proposes an adaptive Kriging-based fourth-moment method for reliability analysis under complex state equations. The proposed method demonstrates better applicability and efficiency compared to existing methods. Several numerical examples are provided to validate the effectiveness and accuracy of the proposed method.

Institutional barriers to the development of small-scale power generation in Russia

The energy strategy of Russia involves a transition to a diversified energy generation characterised by a structural diversity of plant types, as well as the use of small-scale energy technologies. The purpose of the study is to identify the barriers that hinder the implementation of small-scale power generation in the Russian Federation and justify the avenues for its development. Methodologically, the paper relies on the systems approach. Methods of content and logical structural analysis, in-depth interviews are applied. The empirical evidence comes from analytical reports, normative and legal documents, as well as results of surveys of 96 specialists in the field and heads of power plants and power engineering enterprises conducted during 2021– 2023. The findings indicate there are four groups of problems in the Russian energy system: technological backwardness; difficulties with integration of small-scale power generation facilities into the energy market; absence of state support mechanisms; surplus of power generation capacity. Accordingly, the paper provides recommendations for overcoming them, in particular, it is necessary to introduce mechanisms for the support of small-scale power engineering and integration with engineering and consultancy companies, as well as make use of energy service agreements; second, to introduce standards for connecting small-scale power generation facilities, develop guidelines for designing and commissioning them; third, to amend tax regulations and learn from successful foreign experience; fourth, to replace retired power generation equipment with new small-scale power generation facilities located closer to load centres. The theoretical significance of the research is linked with detailing the concept “small-scale power generation” as a segment of energy sector as well as its structure in relation to the Russian Federation, specifying classification characteristics of low-capacity power units. The findings are practically valuable for government authorities, power generation enterprises and equipment manufacturers due to the developed organisational and methodological guidelines.

Adaptive management model of the higher education system in the context of the transition to the digital economy

   Purpose: of the study is to develop an adaptive model of higher education system management in the context of digital transformation of the economy.   Methods: the methods of interdisciplinary, structural and logical analysis, typologization of management models, rating and expert assessments were used in the work. The methodological basis of the research was: a three-sided model of higher education management assessment, a "management cube", including a model of new managerialism, a two-plane model of higher education system assessment, level-based, adaptive approaches to higher education management.   Results: based on the analysis of the higher education management system in the context of the digital transformation of the economy, the need for the formation of new adaptive mechanisms and management models of this system as an area where human capital is formed and developed, necessary for the breakthrough development of the country. Also, the trends of digitalization in the field of higher education have been identifi ed. Recommendations for its adaptation to the digital transformation of the economy have been developed and substantiated. As a key tool of the adaptive management model, an organizational model of adaptive management of the higher education system has been developed, which makes it possible to adapt the entire education system to the challenges of digital transformation of the economy.   Conclusions and Relevance: the developed organizational model will make it possible to build an eff ective work of the higher education system using adaptive management mechanisms, that allow it to optimally adapt to modern transformational processes, that occur according to cyclical crisis phenomena and the next industrial revolution. Digital transformation and the conditions of Industry 4.0, as well as the technological singularity, which is already the reality, do not allow us to strategically correctly build one specifi c model of management of the higher education system, since the above-mentioned processes become the trigger for constant transformations, including in the field of education. The organizational model of adaptive management proposed by the authors is innovative, allowing to adapt iteratively to the ongoing transformations of social and economic systems. Thus, this model is strategically relevant and promising for the both modern conditions of functioning and long-term development of the education sector.

Animalism in the Design of Clothes of the ХХ and Early XXI Centuries

The article presents an overview and systematisation of fashion design projects using animalistic motifs. The purpose of the study is to identify the manifestations of animalistic images in costume and the differences in their meanings in different historical periods. The research methodology is based on the application of methods of source, art, aesthetic, structural and compositional analysis. The scientific novelty lies in highlighting the stages of animalism development in the twentieth – early twenty-first centuries and identifying its main manifestations in costume. The results of the study are based on empirical material from designers and fashion houses that actively used and developed animalism in their work. Conclusions. As a result of the study, we conclude that there are various ways of manifesting animalism in fashion design, from copying animal images entirely to introducing their individual parts into the design or using photographs and artistic images. And while in the early twentieth century, costumes used mostly elements of animal skin, fur and feathers, and exotic animals and birds emphasised the status of the elite strata of society, with the development of technology and the spread of mass production of clothing, imitation gradually became popular. The destruction of the natural environment and the dominance of the artificial one led to the spread of fashion inspired by wildlife. Gradually, a style direction in fashion design was formed, which is now considered «fantasy classics». Over time, animalistic motifs have become visual carriers of «eco-fashion» and «eco-consciousness», reminding us of the need for significant transformations in the global consciousness of humanity. The flourishing of animalism in recent decades reflects the socio-cultural trends in society. The symbolism and interpretation of animalistic images in costume design reflects the care and desire to preserve the natural heritage in a world that is increasingly influenced by technological development.

Meta-model based sequential importance sampling method for structural reliability analysis under high dimensional small failure probability

Reliability analysis poses a significant challenge for complex structures with stringent reliability requirements. While Sequential Importance Sampling (SIS) and Subset Simulation (SUS) have proven highly effective in addressing high-dimensional problems with small failure probabilities, the computational burden of mechanical simulations remains substantial due to the time-consuming nature of numerical simulation processes. Consequently, this paper introduces a novel approach, denoted as AK-SIS, which combines SIS with Kriging metamodeling specifically designed to address computational challenges associated with small failure probabilities. The fundamental principle of this approach involves utilizing AK-MCS technology (Echard et al., 2011) [1] as a precursor to the SIS approach to initially generate metamodels. These metamodels are then employed in lieu of performance functions in subsequent steps, significantly reducing the number of function calls required to simulate complex engineering problems when applying SIS techniques directly. By inheriting the advantages of SIS, AK-SIS has demonstrated its suitability for reliability analysis in scenarios involving high-dimensional spaces and small fault probabilities. Furthermore, AK-SIS is not limited by the shape of the failure domain, eliminates the need to solve the design point, and is particularly well-suited for analyzing reliability in cases of discontinuous failure domains, multiple failure domains, as well as complex failure domains and rare events. The efficacy of AK-SIS is substantiated through rigorous evaluation encompassing nonlinear, high-dimensional examples, and an engineering application. These empirical validations collectively contribute to a robust methodological framework for reliability analysis of intricate structures characterized by stringent reliability requirements.

Object: Clusters are a relatively new form of organization, risk and profit sharing, and competitiveness enhance ment for both the global and Ukrainian economies. The potential of the cluster development model is significant, and, most importantly, it has been justified in developed countries worldwide. In particular, global practice confirms that the functioning of the most prosperous economies is supported by advantages in modern production technologies and man agement. Therefore, successful development of any level is possible through the comprehensive application of modern strategic management concepts. Thus, the object of the study is to reveal and substantiate the effectiveness of cluster model in establishing special economic zones in Ukraine. Methods: The paper uses general scientific and special methods, that are: the dialectical method of understanding cluster model for establishing special economic zones; comparative analysis methods; methods of empirical research, methods of statistical and structural analysis; methods of historical and logical analysis; identifying individual parts of an object, methods of system approach, identifying cause-and-effect relationships. Findings: Custers are established on the base of a unique internal environment and infrastructure specific to a par ticular region. This allows leveraging the competitive advantages of enterprises in a specific area through integration. A cluster serves as a stimulus for economic development, and regionalism forms the basis for its sustainable growth. Re gionalism is of great significance in selecting priority investment areas, as it can influence the level of uncertainty risk during the assessment of regional investment projects. Its effectiveness is confirmed by cluster development of the child nutrition project presented in the paper (Ivano-Frankivsk region, Ukraine). Conclusions: Cluster approach makes it possible to use available resources more efficiently. The cluster approach is connected with the policy of capacity-building as well as increasing competition profitability of national economies. There are also some cluster formations on the territory of Ukraine. Сluster is a convenient form of organizing a free economic zone. At the same time, each government develops its own approaches to the creation of clusters and regula tion of their activities, accordingly, organizes the activities of those responsible for the implementation of the national strategy of sustainable competitive development.

Methodological Approach to Comprehensive Assessment of Living Standards in Russian Regions

Introduction. Improving the living standards of the population is the most important task facing public authorities. However, its solution is impossible without a clear understanding of what is meant by this definition and how this indicator should be assessed. Despite the wide representation of studies on this issue, there is actually no unified position and, consequently, no generally accepted assessment. The use of private indicators gives contradictory results. In this regard, the aim of the study is to develop a methodology for the comprehensive assessment of living standards in Russian regions. Materials and Methods. The methods of grouping, dynamic and structural analysis, correlation analysis and others were applied in the framework of the task. The information base of the study was formed by the data of the Federal State Statistics Service of Russia, as well as the works of domestic and foreign scientists in the field under consideration. The research proposed an approach to the formation of an integral assessment of the standard of living of the population of Russian regions, based on a two-stage convolution of 22 private indicators divided into five groups, taking into account the weighting coefficients. Further the methodology was tested on the data on the regions of the Russian Federation. Results. According to the results of the approbation, the ratings of regions by standard of living for 2017‒2021 were formed, which allowed us to consider its dynamics. It was revealed that, in general, the positions of leaders and outsiders remain stable; the differentiation between regions does not decrease. At the same time, while outsiders have weak positions in the overwhelming number of indicators, leadership can be due to different components of the integral indicator. Discussion and Conclusion. The obtained results can be used by the authorities responsible for the development and implementation of state policy in the field of regional development, social security and other related areas. Forecast assessments allow us to identify threats to the realization of the task of improving living standards in Russian regions.

The article actualizes the problem of socio-cultural and ethnic identity of the Tatar people and the need to cherish and preserve the traditions of the Tatar family. The authors propose to discuss the practical aspects of the development of ethnic processes and the main directions of increasing the importance of ethnic characteristics in the humanization of social relations and the mission of ethnic positions in human life. Analysis of the literature on the problems of ethnic identity, detailing the characteristic desire of different peoples to support and preserve their own identity, determine both the possibility and the need to emphasize the inimitability and uniqueness of social and humanistic practices of their ethnoculture, taking into account the growth of understanding and comprehension of belonging to their ethnos, i.e. national consciousness and ethnic community. The aim of the research was to study and reveal the dialectical dynamic development of the main directions of the traditional national culture of the Tatar people. In modern conditions of active digital transformations of society, an attempt was made to show creative practices of educating children and adolescents on the basis of careful attitude to the national culture, to the national pedagogical experience, which are represented in family traditions and rituals, in holidays, games and folklore with the help of methods of structured analysis. Based on the interpretation of the research results, the experience of the ethnic system of education in the Tatar family is generalized and its features and socio-cultural humanistic functions are reflected; the essential characteristics of humanization of education in the Tatar ethnos, conveying the phenomenology of traditional pedagogical culture in the conditions of digitalization of socio-cultural processes, are shown; effective cultural and informational exchanges between the educational institution and the family in its ethno-pedagogical space are reflected.

A mixed uncertain structural reliability analysis method considering random and convex set variables with correlation

AbstractIn this paper, a mixed model reliability analysis method is put forward for the problem of assessing the reliability of complex engineering structures containing both random and convex aggregate variables. By integrating the ellipsoidal model with correlation and the interval model, the uncertainty region characterized by the ellipsoidal model with correlation is optimized with full consideration of the limited amount of engineering structure sample data, and the risk region represented by the reliability model is redefined, a new mixed reliability assessment criterion is established, and the minimum safe nonprobability reliability index of the structure is built. A key reference is offered by the safety limit diagram of constant reliability indexes set for the first time for the optimal design of engineering structure reliability. The proposed mixed reliability model is compared and analyzed with three classical models. The sensitivity of nonprobability reliability indexes, influenced by random variable parameters and correlation coefficients, is analyzed. This verification confirms that the new reliability model not only provides an accurate assessment of engineering structures' reliability but also lowers the computational demands of engineering design. In this paper, aero‐engine blades and wind turbine blades are taken as examples to expound the validity of the reliability model built using this method and its importance to the structural safety analysis of actual engineering.

A Structural Reliability Analysis Method Considering Multiple Correlation Features

The paper analyzes the correlation features between stress strength, multiple failure mechanisms, and multiple components. It investigates the effects of different correlation features on reliability and proposes a method for structural reliability analysis that considers the joint effects of multiple correlation features. To portray the stress–strength correlation structure, the Copula function is utilized and the influence of the correlation degree parameter on reliability is clarified. The text describes the introduction of time-varying characteristics of structural strength and correlation parameters. A time-varying Copula is then constructed to calculate the structural reliability under the stress–strength correlation characteristics. Additionally, a time-varying hybrid Copula is constructed to characterize the intricate and correlation features of multiple failure mechanisms and components. The article proposes the variational adaptive sparrow search algorithm (VASSA) to obtain optimal parameters for the time-varying hybrid Copula. The effectiveness and accuracy of the proposed method are verified through actual cases. The results indicate that multiple correlation features significantly influence structural reliability. Incorporating multiple correlation features into the solution of structural reliability yields safer results that align with engineering practice.

Theoretical substantiation of the definition "sports activities of highly qualified athletes"

The article provides a theoretical substantiation of the definition of "sports activities of highly qualified athletes". When forming a new concept, a logical-methodological technology of definition of concepts was used, which provides for the observance of certain principles. The following methods were used during the research: analysis of literary sources and documents; system analysis method; method of comparison and comparison; method of functional and structural analysis. It has been established that the result of sports activity is an effective combination of training of the organs that perform movement, training of the body's functional systems, and perfection of the neuropsychological mechanisms for regulating movements, states, and behavior. The specific features of sports activities of highly qualified athletes are singled out. Attention is drawn to the fact that when evaluating the success of competitive activities, the reliability of athletes' performances at prestigious international competitions becomes important, which indicates not only the level of mental preparation, but is an integral indicator of the evaluation of the athlete's physical, functional, mental, and mobilization qualities.
 The author's definition "Sports activities of highly qualified athletes" is formulated, which is interpreted as a physical and/or mental activity that involves active interaction with the surrounding reality through educational and training training, which includes technical, tactical, theoretical and psychological training and competitive activities to meet the needs and achieving the planned goal.

Hydro- and aero-elastic response of floating offshore wind turbines to combined waves and wind in frequency domain

AbstractAn analytical approach and numerical solution to determine coupled aeroelastic and hydroelastic response of floating offshore wind turbines of arbitrary shape to combined wind and wave loads is presented. The model considers simultaneously the aerodynamic and hydrodynamic loads on an FOWT and integrates these with finite element method for structural analysis due to the combined loads. The hydrodynamic and aerodynamic loads are determined based on the linear wave diffraction theory and steady blade element momentum method, respectively, and the solution is obtained in frequency domain. The structure may be fixed or floating, located in arbitrary water depth, and may host single or multiple wind towers. The model captures the complete translational and rotational motions of the body in three dimensions, and the elasticity of the blades, tower and the floating platform. To assess the performance of the model, rigid and elastic responses of a FOWT to combined wave and wind loads are computed and compared with available laboratory measurements and other theoretical approaches where possible, and overall very good agreement is observed. The model developed in this study addresses directly three shortcomings of existing approaches used for the analysis of FOWTs, namely (i) determination of the elastic responses of the entire structure including the floating platform, (ii) analysis of the motion and elastic response of FOWTs in frequency domain, and (iii) assessment of responses of FOWTs with single or multiple wind towers.

The Doctrine of the Living Instrument and Evolutionary Interpretation in the Case-Law of the European Court of Human Rights

Relevance. Having developed one of the most complex and advanced human rights protection practices in the world, the European Court of Human Rights has complicated its decision-making mechanism by introducing several doctrines, including the doctrine of the living instrument. The development of the doctrine of a living instrument and an evolutionary method of interpretation in the practice of the Court can be traced to some important cases and problems that have become key and determined the development of the future of the Court itself.The purpose of the article is to analyze the doctrine of the living instrument, the specifics of its application in the practice of the ECHR.Objectives: to analyze various approaches to the study of the nature of the doctrine of the living instrument, to identify trends in the development of evolutionary interpretation, as well as the opinions of various scientists on this issue.Methodology. In the process of working on the study, systematic, comparative legal, historical and legal methods, as well as methods of interpretation, logical and structural analysis were used.Results. It is noted that the concepts of «dynamic interpretation» and «evolutionary interpretation», «the doctrine of intertemporality» and the doctrine of a living instrument should be distinguished. At the same time, there is a risk that the doctrine of the living instrument may violate the sovereignty of Member States if it is used improperly. As a disadvantage, it is also highlighted that this doctrine may damage the legal certainty of the ECHR practice and create a situation where member States do not understand the scope of obligations to which they agree upon accession to the Convention. Based on the nature, it is proposed to divide the evolutionary rulings of the ECHR into 2 categories: rulings of an evolutionary nature and evolutionary rulings.Conclusion. The author concludes that in performing its functions, the Court cannot but apply an evolutionary interpretation, but it must do so reasonably and consistently. The doctrine of the living instrument and the evolutionary interpretation as an instrument of its implementation are a reflection of the generation and those moral values that prevail in society at one time or another.

Generalised scaled boundary isogeometric analysis – a method for structural analysis of naturally shaped timber structures

ABSTRACT Natural building materials, such as naturally shaped tree trunks, have been used in construction since ancient times. Wood is primarily processed as a long, thin product due to its growth and structure, leaving many parts unused. These neglected parts, like branches, can be used for load-bearing structures. However, they require a new parametric description due to material and geometric behaviour differences. It's crucial to transfer these geometries into the calculation model accurately. The surface is described using NURBS based on image data to realise this. Applying the Scaled Boundary Isogeometric Analysis (SBIGA) can directly use these geometries for structural analysis. This method combines the concepts from the scaled boundary finite element method (SBFEM) with the isogeometric analysis (IGA). In this technique, two-dimensional surfaces are scaled to a centre point. When used in the context of thin, long structures, obtuse-angled polyhedrons occur within a patch, leading to numerical condition problems. This motivates this contribution to modify the conventional SBIGA towards a generalised scheme. This work introduces a generalised SBIGA approach, employing a scaling centre line instead of a scaling centre point. This enables the analysis of slender, curved objects without additional structure partitioning, simplifying the preprocessing while improving the performance.

Efficient stochastic modal decomposition methods for structural stochastic static and dynamic analyses

AbstractThis article presents unified and efficient stochastic modal decomposition methods to solve stochastic structural static and dynamic problems. We extend the idea of deterministic modal decomposition method for structural dynamic analysis to stochastic cases. Standard/generalized stochastic eigenvalue equations are adopted to calculate the stochastic subspaces for stochastic static/dynamic problems and they are solved by an efficient reduced‐order method. The stochastic solutions of both static and dynamic equations are approximated by stochastic bases of the stochastic subspaces. Original stochastic static/dynamic equations are then transformed into a set of single‐degree‐of‐freedom (SDoF) stochastic static/dynamic equations, which are efficiently solved by the proposed non‐intrusive methods. Specifically, a non‐intrusive stochastic Newmark method is developed for the solution of SDoF stochastic dynamic equations, and the element‐wise division of sample vectors is used to solve the SDoF stochastic static equations. All of these methods have low computational effort and are weakly sensitive to the stochastic dimension, thus the proposed methods avoid the curse of dimensionality successfully. Two numerical examples, including two‐ and three‐dimensional spatial problems with low and high stochastic dimensions, are given to show the efficiency and accuracy of the proposed methods.

Factors affecting small and medium enterprises access to capital: Evidence from Vietnam

Purpose: The capacity of a business to operate and grow depends on its capital, particularly for small and medium-sized businesses (SMEs). However, access to capital sources depends on many factors such as collateral assets, business plans requiring loans, the social relations of business owners, etc. This study identifies factors affecting SMEs' access to capital in Vietnam.
 Design/Methodology/Approach: A typical survey was conducted on 450 SMEs in Vietnam, and structural model analysis methods were employed through PLS-SEM software to analyze the data.
 Findings: Research results show that there are nine groups of factors affecting the ability of SMEs in Vietnam to access capital  ranked from high to low level of influence, including (i) operational characteristics of the business, (ii) financial reporting, (iii) financial behaviour of enterprises, (iv) social relations of enterprises, (v) capability of the enterprise, (vi) production and business plan of the enterprise, (vii) ability to adapt to the risks of the enterprise, (viii) characteristics of the business owner and the lowest is institutional  environment.
 Conclusion:  Regression analysis proved to be useful in identifying nine groups of elements that impact SMEs' access to capital in Vietnam. The study has proposed management implications to improve access to capital for SMEs in Vietnam.
 Research Limitations and Implications: The study selected samples based on the principle of random convenience, so the study's sample does not represent all SMEs in Vietnam according to the distribution of regions and territories where the businesses are located.
 Practical Implications: This research has practical significance in supporting managers at SMEs to make decisions to improve access to capital for businesses contributing to sustainable business development.
 Contribution to the Literature: This research makes a significant contribution to the field of practical research on capital and capital access for SMEs in Vietnam.

Bayesian active learning line sampling with log-normal process for rare-event probability estimation

Line sampling (LS) stands as a powerful stochastic simulation method for structural reliability analysis, especially for assessing small failure probabilities. To further improve the performance of traditional LS, a Bayesian active learning idea has recently been pursued. This work presents another Bayesian active learning alternative, called ‘Bayesian active learning line sampling with log-normal process’ (BAL-LS-LP), to traditional LS. In this method, we assign an LP prior instead of a Gaussian process prior over the distance function so as to account for its non-negativity constraint. Besides, the approximation error between the logarithmic approximate distance function and the logarithmic true distance function is assumed to follow a zero-mean normal distribution. The approximate posterior mean and variance of the failure probability are derived accordingly. Based on the posterior statistics of the failure probability, a learning function and a stopping criterion are developed to enable Bayesian active learning. In the numerical implementation of the proposed BAL-LS-LP method, the important direction can be updated on the fly without re-evaluating the distance function. Four numerical examples are studied to demonstrate the proposed method. Numerical results show that the proposed method can estimate extremely small failure probabilities with desired efficiency and accuracy.
