When teachers collaborate, they can build on their competencies by learning from each other, feeling more confident, supported and meaningful. Using the possibilities of information technology for sharing resources and teamwork in a secure digital environment, pedagogical specialists and students create a school community based on trust, respect and mutual assistance. Coteaching is very suitable for classes and groups in which students work at different levels. This provides an opportunity for students with more knowledge and for students with low educational results to acquire as much knowledge, skills and competences as possible.<\/p>\n Keywords:<\/em> collaborative teaching; cloud technologies; innovative practices; training<\/p>\n SEE MORE<\/a><\/p>\n <\/p>\n <\/p>\n <\/p>\n Georgi Kostov<\/strong><\/p>\n Agricultural University \u2013 Plovdiv (Bulgaria)<\/em><\/p>\n https:\/\/doi.org\/10.53656\/voc25-3-4-03<\/a><\/p>\n Abstract. <\/strong>In recent years, there has been an increasing discussion about \u201egreen\u201c economy in vocational education. Climate change, the influence of environmental factors, problems, related to food quality and nutrition of the population, as well as economic and political problems on a global scale are the main reasons for the need for \u201egreen\u201c education starting from vocational high schools of agriculture. The \u201egreen\u201c skills are in high demand as many jobs increasingly require these competencies, and these skills are essential for preserving or restoring the environment, as well as for \u201egreening\u201c or \u201egreenifying\u201c the existing jobs. The article presents the essence of green skills, describes their conceptual framework and develops methods and pedagogical approaches for the successful formation of green skills in vocational education in agricultural disciplines.<\/p>\n Keywords: <\/em>\u201egreen\u201c economy, \u201egreen\u201c education, \u201egreen\u201c skills, vocational education, agricultural disciplines<\/p>\n SEE MORE<\/a><\/p>\n <\/p>\n <\/p>\n <\/p>\n Tatyana Georgieva<\/strong><\/p>\n Vocational High School of Forestry and Woodworking <\/em><\/p>\n \u201cNikolay Haitov\u201d (Bulgaria)<\/em><\/p>\n https:\/\/doio.rg\/10.53656\/voc25-3-4-04<\/a><\/p>\n Abstract.<\/strong> The aim of this publication is to present the application of innovative teaching methods aimed at overcoming excessive theorization and boredom in literature classes, and at increasing students\u2019 motivation to be active participants in the educational process.

Positive Energy Districts (PEDs) are a cornerstone of the European Union\u2019s strategy for climate neutrality by 2050. A PED is an urban area that annually produces more renewable energy than it consumes, while maintaining affordability, livability, and social acceptance. Designing such districts requires an integrated and multidisciplinary approach that goes beyond building-level optimization and addresses district-scale synergies.<\/p>\n This paper outlines the key design principles for PEDs:<\/p>\n \u2013 Energy efficiency first, through passive architectural strategies and high-performance building services<\/p>\n \u2013 Renewable energy integration, maximizing local solar, wind, geothermal, and bio-based resources<\/p>\n \u2013 Smart energy management, using digital platforms, storage technologies, and demand-side flexibility<\/p>\n \u2013 Multi-scale integration, connecting buildings, infrastructure, and mobility into a coherent energy ecosystem<\/p>\n \u2013 Stakeholder engagement and governance, ensuring participatory planning and long-term acceptance<\/p>\n The study emphasizes that PEDs represent not only a technological innovation but also a socio-economic transition, requiring strong collaboration across disciplines and sectors. By applying these principles, PEDs can significantly contribute to urban decarbonization, energy resilience, and the achievement of the EU\u2019s climate and energy objectives.<\/p>\n Keywords:<\/em> Positive Energy Districts, Energy efficiency, Renewable integration, Smart energy management, Urban decarbonization<\/p>\n SEE MORE<\/a><\/p>\n <\/p>\n <\/p>\n <\/p>\n Rumyana Komarska<\/strong><\/p>\n National Vocational High School of Precision Engineering and Optics<\/em><\/p>\n \"M.<\/em> V.<\/em> Lomonosov\"<\/em> (<\/em>Bulgaria<\/em>)<\/em><\/p>\n https:\/\/doi.org\/10.53656\/voc25-3-4-08<\/a><\/p>\n Abstract.<\/strong> This paper explores the key challenges that AI introduces to the Bulgarian school environment, focusing specifically on its impact on the roles of teachers and students.

This article proposes a structured internal conformity assessment methodology tailored to Personal Protective Equipment (PPE) and applied within TOOLSWORLD \u2013 Bulgaria. Building on a previously validated system for power equipment, the approach translates EU legal requirements into an operational workflow for documentation collection, expert verification, traceability, and risk-based categorization of products into five compliance categories (Cat.1 \u2013 Cat.5). The regulatory basis centers on Regulation (EU) 2016\/425 on PPE, complemented by the New Legislative Framework guidance (\u201cBlue Guide\u201d 2022) and the horizontal market-surveillance regime in Regulation (EU) 2019\/1020. The framework operationalizes presumption of conformity via harmonized standards (e.g., EN ISO 21420, EN ISO 13688, EN 166, EN 149, EN 388), while also accounting for chemical-safety obligations relevant to materials (e.g., REACH Annex XVII PAHs; POPs restrictions on SCCPs) where applicable. The study contributes a replicable model for companies managing diverse PPE portfolios, aligning regulatory compliance with practical risk management and audit readiness. It also situates the method within broader literature on conformity assessment and supply-chain assurance for protective equipment.<\/p>\n Keywords:<\/em> Conformity assessment, Personal protective equipment (PPE Regulation (EU) 2016\/425, Harmonized standards (EN ISO 21420, EN 388, EN 149)<\/p>\n SEE MORE<\/a><\/p>\n <\/p>\n <\/p>\n <\/p>\n Victor Arsov<\/strong><\/p>\n University of Chemical Technology and Metallurgy (Bulgaria)<\/em><\/p>\n Marieta Yancheva-Popova<\/strong><\/p>\n Technical University of Sofia (Bulgaria)<\/em><\/p>\n Desislava Koleva<\/strong><\/p>\n Technical University of Sofia (Bulgaria)<\/em><\/p>\n https:\/\/doi.org\/10.53656\/voc25-3-4-10<\/a><\/p>\n Abstract<\/strong>. This article presents a structured methodology for the internal conformity assessment of power equipment, developed and applied within TOOLSWORLD \u2013 Bulgaria. The study addresses the regulatory framework of the European Union, including the Machinery Directive, Low Voltage Directive, Electromagnetic Compatibility Directive, RoHS Directive, and Regulation (EU) 2019\/1020, and emphasizes the dual role of conformity assessment as both a legal requirement and a strategic tool for risk and quality management. A six-stage methodology is proposed, encompassing documentation collection, verification, cross-referencing with product lists, data extraction, classification into five conformity categories (Cat.1 \u2013 Cat.5), and visualization of results. Applied to a portfolio of 482 products, the methodology revealed that nearly half (47.1%) of the products were in partial conformity (Cat.2), while only 4.8% achieved full conformity (Cat.1). The results highlight critical compliance risks, particularly products with expired or missing documentation (Cat.4 and Cat.5), and underline the importance of systematic document management. The study contributes to both practice and academia by bridging regulatory requirements with practical implementation, offering a replicable model for internal conformity systems that can enhance risk management, audit readiness, and market surveillance.<\/p>\n Keywords:<\/em> Conformity assessment, European Union directives, risk management, product compliance, internal audit, quality management, market surveillance, certification, power equipment, technical regulation<\/p>\n SEE MORE<\/a><\/p>\n <\/p>\n <\/p>\n <\/p>\n Sofoklis Christoforidis<\/strong><\/p>\n Efstathios Titopoulos<\/strong><\/p>\n Democritus University of Thrace (Greece)<\/em><\/p>\n Boryana Mihaylova<\/strong><\/p>\n Technical University of Sofia <\/em>(Bulgaria)<\/em><\/p>\n Athanasios Thomopoulos<\/strong><\/p>\n Dimitrios Thomopoulos<\/strong><\/p>\n Eleni Kromitoglou<\/strong><\/p>\n Democritus University of Thrace (Greece)<\/em><\/p>\n https:\/\/doi.org\/10.53656\/voc25-3-4-11<\/a><\/p>\n Abstract. <\/strong>The advancement of Information and Communication Technologies (ICT) in the healthcare sector presents significant opportunities for the implementation of Electronic Health Record (EHR) systems. Such systems enable both healthcare professionals and patients to access medical histories directly, thereby enhancing transparency and continuity of care. However, the implementation of an EHR system is a complex undertaking. The chosen implementation strategy plays a critical role in integrating existing health information systems and ensuring their interoperability. This paper aims to design and model an integrated information system for Electronic Health Records in the context of occupational medicine. It examines best practices adopted globally during the deployment of EHR systems. We propose a distributed architecture in which employee health data is stored locally within each organization\u2019s database. A centralized reporting system is introduced to facilitate access to specific medical record data points as needed. Furthermore, we advocate for the integration of artificial intelligence into the system to monitor employee health. This monitoring would leverage both the medical examination data contained in the EHR and contextual information about the work environment.<\/p>\n \u00a0<\/em>Keywords:<\/em> Interoperability, Semi-distributed architecture, Data quality management, Artificial intelligence integration, Occupational environment monitoring<\/p>\n SEE MORE<\/a><\/p>\n <\/p>\n <\/p>\n <\/p>\n Sofoklis Christoforidis<\/strong><\/p>\n Efstathios Titopoulos<\/strong><\/p>\n Democritus University <\/em>of Thrace (Greece)<\/em><\/p>\n Boryana Mihaylova<\/strong><\/p>\n Technical University of Sofia (Bulgaria)<\/em><\/p>\n Eleni Kromitoglou<\/strong><\/p>\n Stergios Intzes<\/strong><\/p>\n Democritus University <\/em>of Thrace (Greece)<\/em><\/p>\n https:\/\/doi.org\/10.53656\/voc25-3-4-12<\/a><\/p>\n Abstract. <\/strong>The Job Shop Scheduling Problem (JSSP) is a long-standing combinatorial optimization problem studied since the 1960s.
