MIGRATION IN THE SLOVAK REPUBLIC
Full text linkSlovakia is not one of the traditional destination countries for migrants. It is a culturally homogeneous country that was not affected by the dramatic increase in migration during the 20th century. Until recently, the Slovak Republic was almost exclusively a country of origin for migrants, i.e. a country from which citizens migrated abroad for various reasons. More significant changes were brought about only after Slovakia joined the European Union and the Schengen area. Foreigners today make up 5.13 percent of the population in the Slovak Republic and their number is slowly but continuously growing. The aim of the paper is to analyze the number of migrants in the Slovak Republic in terms of nationality, age and gender. The results of the survey showed that most immigrants to Slovakia come from Europe, from neighboring countries, such as the Czech Republic, Hungary, Austria and Poland. From countries outside the EU, in addition to Ukraine, they come from Serbia, for example. In terms of age, the most migrating people are in the age structure between 35 - 40 years old. In terms of gender, the representation of men and women is approximately at the same level. In conclusion, it can be stated that the reasons for migration from/to Slovakia are primarily economic and social factors

Full text linkThe paper analyzes some major aspects of the activities of the Central Bank of Bulgaria – the Bulgarian National Bank (BNB) on the eve of the country’s membership in the Euro area. The topic of the paper is undoubtedly relevant, as the country’s membership in the Eurozone has been a key strategic goal of Bulgarian economic policy since the country joined the EU as a full member on 1 January 2007. The main attention in the paper is paid to the key changes in the BNB activities in the following areas: regulatory framework of the BNB and its compliance with the European legal framework, primary objective and basic tasks of the BNB, functional structure and management structure of the BNB. The paper also presents the fulfilment of the Maastricht criteria by Bulgaria according to the latest convergence report published by the ECB in June 2025
MEDICAL EPONYMS AND DESCRIPTIVE TERMINOLOGY ACROSS SPECIALTIES: PATTERNS OF USE, TRANSLATION, AND REPRESENTATION ON MEDICAL PLATFORMS
Full text linkMedical eponyms have been an integral part of medical terminology, especially in clinical language across diverse medical specialties. However, their continued use in the medical field has sparked debate surrounding clarity, cultural relevance, and international consistency. This paper investigates the role and representation of eponyms in medical discourse, with a particular focus on Romanian clinical and public health contexts. This study explores the historical, mythological, and linguistic origins, analyzing their grammatical forms and classification patterns, as well as trends in their usage and decline within various medical disciplines. Particular attention is also given to their descriptive equivalents, as well as to their translation and adaptation within the Romanian medical context. By reviewing both international and national literature, along with Romanian medical websites, notably Regina Maria and MedLife, the study reveals that eponyms remain prevalent in professional and clinical settings despite a growing trend toward descriptive terminology
THE HASHTAG EFFECT: FROM LANGUAGE EVOLUTION TO LANGUAGE LOSS
Full text linkWhile English increasingly establishes itself as a world lingua franca, many local and minority languages are subject to a steady decline, often facing significant challenges to their survival. The current research considers the growing predominance of English on social media and its impact on the future of local languages. Focusing on cases of code-switching that are common among influencers and online communities, the research analyses how digital communication contributes to contemporary language change. While the use of foreign words and phrases may demonstrate linguistic creativity and wider accessibility, they may also accelerate language shift and even diminish the status of less popular languages. Through the observation of social media discourse, this research raises questions whether these trends represent a natural process of language evolution or a catalyst for language decay in the digital age. The findings suggest that while English helps to achieve specific communicative goals and expand global reach, it also subtly displaces native-language functions in certain semantic domains
MELODY IN SPEECH: THE ROLE OF HARMONY PRINCIPLES IN ASSESSING PERSONALITY TRAITS
Full text linkThis research investigates the connection between voice characteristics and personality traits, proposing that shared principles of harmony underlie both music and speech perception. Personality was assessed using both self-report and external ratings based on the NEO Five-Factor Inventory. The perceptual evaluation involved analysing three types of speech samples: a sustained vowel sound [a], a reading passage, and spontaneous speech. To deepen auditory insights, acoustic features of the recordings were examined using the software PRAAT, identifying specific vocal markers tied to individual personality dimensions. The speech signals were also transformed into musical notation via Neuratron AudioScore Professional to analyse pitch intervals and distinguish between harmonic and disharmonic transitions. Findings revealed strong correlations- particularly involving extraversion and neuroticism - between vocal parameters and personality. Key indicators included pitch (F0), pitch variability, jitter, shimmer, harmonics-to-noise ratio (HNR), energy distribution, articulation clarity, and consonance/dissonance in speech melody. Notably, introverted or emotionally unstable individuals tended to show higher values in F0, jitter, shimmer, and HNR, whereas emotionally stable and extroverted individuals displayed greater pitch variability and more energy in higher frequencies. Features like articulation precision and melodic pitch transitions also played vital roles in distinguishing personality profiles. The study enhances our understanding of vocal expression’s influence on perception and suggests applications in speech analysis technology, recruitment processes, psychological counselling, and career guidance
HEAT RECOVERY WITH TREATED WASTEWATER AS A LOWER HEAT SOURCE
Full text linkNew technical solutions in wastewater sector are being strongly analyzed due to the increase in energy costs in this field. The aim of the research is to optimize operational costs in wastewater treatment plants as well as their energy independence and neutrality. At first, the main objective in wastewater treatment processes was the adjustment of wastewater quality to the obligatory regulations with no consideration of energy intensity in the system. However, the present requirements in climate protection and energy consumption limitations involve the technological aspects investigations. Therefore, innovative methods are highly respectable. Their purpose is to decrease the energy consumption on one hand, with no negative impact on the environment on the other. One of the approaches involves the heat pump applications with the wastewater as the lower heat source. The energy recovered in the process may be effectively employed in other wastewater treatment processes. The design improves the wastewater treatment plant sustainability. The paper describes the analyzes of obtained thermal energy by means of heat pump supplied with wastewater heat recovery. The studies involve each month of the year for coefficient of performance (COP) calculations. Measurement data were obtained from wastewater treatment plant in Gorzyce, Podkarpackie voivodship in Poland. The research conducted temperature measurements for treated wastewater as well as its flow rates. The results indicate that the heat input ranged between 314.58 kW in January and 2,397.42 kW in August. It proves the seasonal variability in energy potential
EFFECTS OF DIFFERENT IRRIGATION LEVELS AND MYCORRHIZAL INOCULANT ON FRENCH MARIGOLD (TAGETES PATULA L.) GROWTH AND MORPHOLOGY
Full text linkThis research aimed to determine the effects of different irrigation levels, regarding drought stress, on the growth and morphology of French marigold (Tagetes patula L.). The effect of mycorrhizal inoculant on drought stress mitigation was also studied. Apart from growth and aesthetic characteristics, the following morphological traits were observed: plant height, number of branches, green and dry above ground mass, flower mass, flower and stem diameter and number of flowers. Plants were grown in the Faculty of Agrobiotechnical Sciences Osijek greenhouse, and the treatments started when the plants reached the appropriate vegetative growth, a three-leaf stage. The research was set as a randomized block arrangement with five replications and three irrigation treatments (a1 = 100%, a2 = 70%, a3 = 50% of the substrate water retention capacity, WRC). The mycorrhiza treatments (b1 = without mycorrhiza, b2 = with mycorrhiza) contained MycoApply® preparation added during the transplantation (2.5 mL of mycorrhiza per plant) and along with irrigation treatments (10 mL of mycorrhizal preparation was dissolved with 3.5 L of water). Research results indicate that drought stress had a negative effect on observed marigold traits. Still, the mycorrhizal inoculant had a positive effect on some observed traits, regarding marigold tolerance to drought
AUTOMATED PRICING FOR INDUSTRIAL GOODS USING FUZZY LOGIC
Full text linkPricing complex industrial products often involves manual assessment of dynamic factors such as factory load, regional purchasing power, and customer success rates. This paper proposes an automated solution for the final pricing stage, integrating manufacturer and customer-specific conditions using a Service-Oriented Architecture (SOA). Real-time data from ERP systems and MES is processed via web services, while fuzzy logic formalizes expert knowledge into pricing rules. Sales engineers input basic case characteristics, and the system dynamically computes the price factor. An open-source implementation of IEC 61131-7 for fuzzy control programs demonstrates feasibility, showing that automation enhances decision-making, supports knowledge transfer, and offers flexibility for future integrations

OPTIMIZATION OF FRICTION STIR WELDING PARAMETERS FOR SIMILAR AND DISSIMILAR ALUMINUM ALLOYS AA5083-H111 AND AA7075-T651
Full text linkIn recent years, the increasing demand in the industry for lightweight and durable materials has driven research into various aluminum alloys, which are relatively inexpensive and offer a high strength-to-weight ratio. Aluminum alloys are utilized across multiple sectors such as aerospace, automotive, and shipbuilding. Many applications require welding similar or dissimilar alloys, which, with conventional fusion methods, are often impossible or result in degraded weld quality. Friction Stir welding, a solid-state welding technique, is increasingly popular because it is eco-friendly, energy-efficient, and prevents common issues like solidification cracks. The goal of this work was to determine the optimal parameters for successful similar and dissimilar welds. Accordingly, three tools were designed and manufactured to perform butt welds on thin alloy plates of 5083-H111 and 7075- T651, both similar and dissimilar. The parameters were optimized, and the weld microstructure was examined using an optical microscope. Lastly, micro-hardness measurements were taken on the optimal welds
