Specific mechanical properties of superplastically formed components and resulting applications for vehicles
No full textThe technical requirements to produce parts as light as possible with more complex geometries are ever increasing in recent years in automotive industries, rail vehicle and aerospace. Manufacturing technologies such as super-plastic metal forming, which had been considered as a niche technology earlier, is now gaining greater technical relevance for industrial size production. The parts that have been generated through super-plastic forming in innovative vehicle for example Mercedes SLS AMG reflect the industrial activity in this area. Manufacturability of thin-walled structures enables lightweight design. Also the tool and manufacturing costs are lower in comparison. However, the main challenge could be found in maintaining exact process parameters. There is a large research potential in super-plastic forming; from the determination of optimal material data through process simulation to manufacturing of real parts and their characterization. In the framework of the project international Bureau of the Federal Ministry of Education and Research UKR005/08 “Manufacture of parts with special properties” a preliminary research work has been carried out.
The scientific challenge lies in the characterisation of forming properties of light metal alloys in super-plastic forming. In this preliminary research, the “full factorial experiment” methodology has been applied, regression equations have been developed and a mathematical model derived. This shows interrelationship between mechanical properties of the material and the variable process parameters, leading to material characterization. Hence advantages of cost and time have been achieved; the important parameters for the design of parts through super-plastic forming are determined. The analytical results are then verified with finite element method ─ simulations and through experiments with general parts

Abstract
The article conceptualizes the phenomenon of “ecological values”, which is the basis of educational and professional training of future teachers of natural sciences. The research focuses on identifying the system of values and their hierarchy in order to achieve at least two key results: 1) the formation of a higher level of a value sphere of future natural sciences teachers and improvement of the process of acquired values transfer; 2) improvement of learning outcomes (improvement in behavior, awareness, knowledge). Based on the extensive analysis of the scientific literature, the research suggests the meaningful characteristic of the formulated ecological values of the future natural sciences teachers. As a result, the research has considered the ecological values of future natural sciences teachers as an integrated value block in the system of their value orientations.

Complications of epidural adhesiolysis
Epidural adhesiolysis is a minimally invasive procedure used to treat neuro-compression pain of the lumbosacral part of spine with degenerative diseases. Thanks to being minimally invasive and to its high efficiency, the rate of this procedure in recent years has increased significantly. On a material of 760 patients we analyzed the mistakes and complications related to epidural adhesiolysis. The complications of varying severity were observed in our 297 (30.0%) patients. Of these, the complications which did not require any modifications of treatment strategies, or its minor correction occurred in 277 (36.4%) patients; complications requiring reinstallation of the catheter were observed in 15 (1.9%) patients; complications of moderate severity, as epidural hematoma, epiduritis we noted in 5 (0.6%) patients; threatening complication of spontaneous rupture of the dura mater followed by the catheter hypertonic solution of sodium chloride, we observed in one (0.1%) case.
Key words: epidural adhesiolysis, neuro-compression pain, complications
Інтегрований підхід ERP-BPMS для оптимізації управління житлово-комунального господарства: кваліфікація персоналу, витрати на обслуговування та вибір підрядника
No full textThe object of the study is the integrated ERP–BPMS framework designed to optimize housing and communal services (HCS). The most problematic area identified during audit was the fragmentation of personnel qualification assessments, maintenance cost forecasting, and outsourcing decisions, causing inconsistent performance metrics, increased diagnostic errors, and prolonged service-resolution times under budget constraints.
The research implemented three approaches: an Integral Evaluation Method (IEM) for quantifying staff competencies, a Maintenance Cost Assessment module for enhanced budget planning, and an IEM-based decision mechanism for comparing in-house versus outsourced work. These methods were integrated into the Business Operation System – Central Information System (BOS CIS) with an Information Administrator (IA) role that cross-validates digital logs against manual safety and compliance checklists.
Implementation increased the Integral Qualification Score from 9.8 to 64.0, reducing diagnostic errors by 66 % and issue-resolution times by 50 %. Cost prediction accuracy improved from 0.76 to 0.93, while outsourcing decisions shortened project durations by 25–28.6 % and enhanced financial efficiency by 6 %. Data retrieval times decreased by 75 %, and the Information Utilization Rate rose from 65 % to 88 %. These improvements stem from the framework's real-time processing of both positive and negative performance factors and its hybrid human-machine validation process.
This synergy enables accurate, data-driven decisions that optimize resource allocation under strict budget limitations. Unlike solutions focusing on isolated elements, this integrated platform simultaneously addresses personnel development, cost modeling, and strategic outsourcing, increasing operational transparency and adaptability.
The framework is recommended for large-scale service environments where uninterrupted operation, cost-effectiveness, and high service quality are essential. By combining automated analytics with oversight, it provides a scalable model for enhancing project performance and strategic decision-making in resource-constrained service sectors.Об'єктом дослідження є інтегрована ERP–BPMS-платформа для оптимізації управління житлово-комунальними послугами (ЖКП). Найбільш проблемним аспектом є розрізненість процесів оцінювання кваліфікації персоналу, прогнозування витрат на обслуговування та ухвалення рішень щодо аутсорсингу, що призводить до нерівномірних показників, підвищеного рівня діагностичних помилок і затримок при усуненні несправностей в умовах обмежених бюджетів.
У дослідженні застосовано три підходи: інтегральний метод оцінювання (ІМО) для кількісної оцінки компетенцій персоналу, модуль оцінки витрат на обслуговування для точнішого планування бюджету та механізм на базі ІМО для вибору між виконанням робіт власними силами або через аутсорсинг. Ці методи інтегровано в систему Business Operation System – Central Information System (BOS CIS) із роллю інформаційного адміністратора (ІА) для перевірки цифрових журналів з ручними контрольними списками.
Впровадження підвищило інтегральний показник кваліфікації з 9,8 до 64,0, зменшивши діагностичні помилки на 66 % і час усунення неполадок на 50 %. Точність прогнозування витрат зросла з 0,76 до 0,93, а аутсорсинг скоротив тривалість проєктів на 25–28,6 % і покращив фінансову ефективність на 6 %. Час пошуку даних скоротився на 75 %, а коефіцієнт використання інформації зріс з 65 % до 88 %. Ці покращення пов'язані з обробкою позитивних і негативних факторів у реальному часі та гібридною системою верифікації.
Завдяки такому поєднанню забезпечується оптимальний розподіл ресурсів та зменшення ризиків за умов обмежених коштів. На відміну від систем, що охоплюють окремі аспекти, інтегрований підхід одночасно впливає на формування кваліфікованого персоналу, прогнозування витрат і аутсорсингові стратегії, підвищуючи прозорість та гнучкість.
Платформу рекомендовано для масштабних сервісних середовищ, де критичними є безперервність роботи, оптимізація витрат та якість послуг. Поєднання автоматизованої аналітики з фаховим наглядом створює надійну модель для підвищення ефективності проєктів і стратегічного планування в умовах ресурсних обмежень

Abstract. The thesis that environmental problems are the most dangerous ones is widely recognized nowadays. In modern educational conditions, a teacher of natural sciences can be a promoter of ecological values. This makes relevant the need to develop new approaches to the training of teachers of this profile.
This study deals with the formation of eco-values of future natural sciences teachers and proposes a number of changes to the educational content of their training by involving the author’s educational and methodological developments – subject “Axiology”, special course “Axiological foundations of training future natural sciences teachers”, and axio-pedagogical training. The material presents an empirical part of the study that reflects the definition and analysis of the dynamics of formation and assimilation of environmental values due to the changes in the educational content.
The research used the following elements of the diagnostic system: method of diagnosing the intensity of subjective attitude to nature “Nature Lover” by V. Yasvin, S. Deryaba and determination of the peculiarities of the formation of ecological consciousness components, methodology of the questionnaire “Ecological concepts”, questionnaire “Determination of the level of assimilation of ecological concepts” by T. Yevdokimova, technique “Incomplete sentences” by O. Hrybanova, and technique “Test of the development level of the ecological consciousness components of the individual” by O. Asafova.
The empirical research established the psychological and pedagogical features of the ecological values development among students.

TUI tipų lyginamasis vertinimas ES-14 ir Vidurio bei Rytų Europos šalyse.
No full textThe main purpose of this master thesis is to determine types of foreign direct investments (FDI) in two distinct parts of the European Union (the EU): in 14 countries that were part of the union in 1995 (EU-14) and 8 new member states in Central and Eastern European (CEE) region that joined in 2004. Master thesis consists of three parts: the analysis of the literature, research and its results, a conclusion and recommendations. Literature analysis focused on review of the theories that led to the development of the FDI, application of them in this work, as well as overview of previous research on the FDI determinants in the CEE region. The author defined proxy variables such as GDP, inflation, wage rate, education and resource rents that acted as representatives of certain types of FDI. Following literature analysis, the author applied defined panel data model to carry out the research into FDI determinants in two regions. After calculations were done, the author found out that FDI in EU-14 countries is mainly positively influenced by GDP per capita, while for CEE region rising wages is negative factor and inflation rate has positive influence. Conclusions were made that the EU, although acting like joint economic union, is not homogenous in attracting FDI. The countries of EU-14 region have shown specialization in market-seeking FDI and CEE region in efficiency-seeking type. The natural resource seeking FDI does not have standing in either of regions and asset-seeking FDI requires further research. Author believes that results of the study can be useful for more precise definition of governmental investment-seeking policies. During this work several research gaps were found, mainly in relationship of education and FDI, which author recommends to explore further
Bilateral cooperation between Ukraine and EU member states on labor migration: current status and prospects for development
No full textThe article reveals the issues of modern bilateral legal regulation of labor migration between Ukraine and EU member states. Bilateral cooperation can be considered the most effective, because it takes into account the actual problems between the participants and is focused on specific subjects. The existing agreements are analyzed, their common and distinctive features are singled out, and the advantages and disadvantages of such agreements are revealed. The author substantiates the conclusion in the article that the Association Agreement does not grant Ukrainian citizens the right to free employment on the territory of EU member states and to free movement within the EU for this purpose. Nothing in the Association Agreement can be interpreted as such that acts as a basis for free employment of Ukrainian citizens. The author has analyzed the agreements that are currently in force with the member states of the European Union, and based on this analysis, he derived the author’s classification, which divides the agreements according to their key characteristics. According to the criterion, author distinguished four types of agreements: cooperation agreements (Belgium); migration flow management agreements (Spain); agreements on mutual employment of citizens and labor activity (Latvia, Lithuania, Poland, Czech Republic); temporary migration agreements (Portugal). The shortcomings of the relevant agreements and ways to improve the future content of such agreements have been identified. The author established interrelation between the agreements concluded in the same period and also allocated the questions which should be fixed in the future bilateral agreements. The article argues that international treaties governing the protection of the rights of migrant workers and employment regulate the basic procedural issues of employment of foreigners in their territory, the requirements for them, as well as the rights he is granted if such requirements are met. The author also identifi es ways to develop bilateral cooperation between Ukraine and EU member states, paying special attention to the following areas: development of the international legal framework with the member states of the Union; institutional cooperation; implementation of international and European norms and standards
Towards the Question of PR’s Social Role and Ethics
No full textThe article reviews pragmatic, conservative, radical, idealistic, neutral, critical, and vulgar-managerial worldview approaches to the interpretation of public relations’ social role in a society wide-familiar within the theory and practice of Western countries. Sharing the American scholar James Grunig’s and his colleagues’ point of view on the normative theory of ethical PR, the author shows that only in case of the practical application of symmetrical (ideal) model of communication between organizations and publics, the social institute of public relations may overcome an utilitarian approach to ethics and become more effective and socially responsible. The author comes to the conclusion that application of such a symmetrical model of public relations in Ukraine will promote the democratic development and creation of a civil society in this country
Pre-Election Campaign Communication and Publicity: Political Phenomenon, Structure, and Functions
No full textFrom political practitioners’ point of view the pre-election campaign publicity is a complicated political phenomenon and at the same time the process built upon the rules of political communication that fulfills a number of consistent functions during campaign. Among these functions are: political party, new election bloc or separate candidate’s name identification; election bloc and can didate’s im age building; election platform identification, issue development and exploitation; campaign messages symbolization and advertising as well as others. The author came to the conclusion that these types of factors in most cases motivate voter choices in elections in Ukraine
