This article examines how this process is organized in a small specialized service center: from initial diagnostics and data backup to soldering operations and bench testing under real-world conditions. Shah et al. (2024) expect the number of embedded control units to rise from 200 to 700 million by 2030. High refurbishment costs make component-level repair increasingly important. The theoretical framework draws on IPC-7711D/7721D and ANSI/ESD S20.20-2021, as well as peer-reviewed publications from 2022–2025. To verify the theoretical propositions, materials from a structured interview with Y. Breusov, a practicing specialist, were utilized, based on a sample of 210 repaired circuit boards from 2023–2024, distributed by type as follows: 60% engine control units, 20% body control units, 10% airbag control units, 10% transmission control units. The analysis showed that the reliability of the result is determined by three conditions: backing up the unit's identification data prior to any soldering operations, testing under actual power load, and ensuring protection against static discharge in accordance with ANSI/ESD S20.20-2021.

A Repair-Modification Evaluation Framework (RMEF) is proposed that evaluates three criteria: lifecycle cost ratio, failure recurrence probability estimated from recorded intervals, and reliability improvement factor. A two-condition decision rule permits modification to be recommended when recurrence probability exceeds 0.80 and reliability improvement exceeds 3.0, even if repair remains less expensive. Verification on two industrial cases confirmed that RMEF identified the modification point earlier than cost-only analysis: a pipe support bracket with shortening crack intervals (recurrence probability 0.92) and a cooling pipe with persistent corrosion (five failures in six years, followed by 48 months corrosion-free after modification).

Each such replacement reduces the volume of hard tooth tissue. Despite constant improvements in materials, the frequency of this complication does not decrease; therefore, the restoration technique and the patient's behavior after treatment play a key role. Objective. To evaluate the structure of risk factors for secondary caries following restorative treatment based on five years of clinical observations and to describe Stoianov's Protocol for secondary caries. Methods. A retrospective analysis of 60–90 confirmed cases of secondary caries per year over a 5-year period in a private dental practice. For each case, the time of onset, type of material, isolation conditions, hygiene level, presence of bruxism, and nature of technical errors in the initial treatment were recorded. Results. Secondary caries was detected predominantly in the first 1–3 years after treatment (45–50% of cases). Among the causes: microleakage (25%), inadequate hygiene (25%), technical errors (20%), bruxism (20%), material properties (10%). Isolation of the working field increased the stability of restorations from 60–70% to 85–90%. After implementing the author's protocol, the incidence of secondary caries decreased from 25–30% to 15–20%. Conclusions. Secondary caries arises from a combination of clinical and behavioral factors; the isolated effect of a single factor is rare. On the part of the dentist, the greatest influence comes from isolation of the working field and adherence to the adhesive protocol. On the part of the patient, the decisive factors are the quality of hygiene and dietary habits. Stoianov's protocol for secondary caries combines these aspects into a single, reproducible clinical algorithm. Feliks Stoianov Copyright (c) 2026 Global Prosperity https://www.gprosperity.org/index.php/journal/article/view/317 Sat, 25 Jul 2026 00:00:00 +0300 https://www.gprosperity.org/index.php/journal/article/view/325 This study presents a systematic literature review of agentic commerce, with particular emphasis on autonomous shopping systems, machine-to-machine transaction protocols, and the governance conditions necessary for their large-scale adoption. Rapid advances in large language models, generative artificial intelligence, and autonomous agent architectures are transforming digital commerce by enabling intelligent agents to search for and assess products, compare suppliers, negotiate transaction terms, execute purchases, coordinate logistics, and manage post-purchase activities with limited human involvement. Despite increasing academic and industry interest, the relevant literature remains fragmented across e-commerce, information systems, artificial intelligence, cybersecurity, digital governance, and consumer behavior research. Following the PRISMA 2020 methodology, this review examines studies published between 2020 and 2026 and retrieved from Scopus, Web of Science, IEEE Xplore, ScienceDirect, SpringerLink, and the ACM Digital Library, supplemented by searches of Google Scholar and arXiv. Following identification, deduplication, screening, eligibility assessment, and quality appraisal, 42 studies were included in the qualitative synthesis. The evidence was analyzed using the AI-Commerce Integration Assessment Framework, which enabled systematic interpretation of the literature across the dimensions of readiness, feasibility, performance, and maturity. The findings indicate a clear transition from AI-assisted product discovery and recommendation systems toward increasingly autonomous purchasing environments in which AI agents operate as active economic actors. However, broader adoption remains limited by concerns related to trust, privacy, transparency, accountability, cybersecurity, user control, and legal responsibility. The review also identifies emerging infrastructures for digital identity, authentication, interoperability, automated negotiation, smart contracts, payment settlement, and dispute resolution. Nevertheless, these mechanisms remain weakly standardized and insufficiently interoperable across platforms and jurisdictions. Overall, agentic commerce is conceptualized as a transition from human-centered digital transactions toward AI-mediated economic ecosystems. Its sustainable development will depend on the coordinated evolution of technical standards, governance structures, explainable AI, consumer protection mechanisms, accountability frameworks, and secure transaction infrastructures. This review provides an integrated synthesis of the field and identifies priorities for future empirical research on real-world implementation, interoperability, regulation, market effects, and human–AI collaboration.

The purpose of the study is to identify psychological mechanisms that ensure the sustainability of youth handball teams and establish the role of the coach in the formation of an appropriate team psychological culture. In the course of the scientific study, general scientific methods of cognition were used: analysis, synthesis, systematization, comparison, as well as content analysis of scientific publications and structural-logical generalization of empirical data. The results of the study showed that teenage handball players who have developed resilience resources - in particular, self-acceptance and a sense of their own competence - cope much better with pre-competition excitement and prevent it from turning into destructive anxiety. It was found that somatic and cognitive anxiety decrease in proportion to the increase in resilience, and this effect increases with increasing sports experience. At the same time, it was found that the level of group cohesion during the season is a statistically significant predictor of the intention of players to continue playing for the same team - and this connection is relevant for both older and younger age groups. Six psychological characteristics that together form team spirit in youth handball are separately systematized: group cohesion, motivational climate, intra-team communication, psychological safety, team identity, and self-efficacy. Each of them is connected to the others through specific mechanisms: for example, the leadership of the coach, aimed at forming a common "we", increases the team identification of the players, which, in turn, creates an environment of psychological safety, where athletes can openly admit mistakes and seek help. It is through these chains of influence that coaching becomes a key factor in team resilience, and not just in the technical improvement of players. It is emphasized that the psychological literacy of the coach is a necessary condition for the conscious management of these processes. The practical significance of the study lies in the possibility of using the obtained results in the development of psychological training programs for youth handball teams and advanced training of coaching staff.

The purpose of the study is to substantiate the author's approach to building such a framework based on the integration of artificial intelligence-based cyber threat detection technologies and data leakage prevention mechanisms. The scientific research used general scientific methods of cognition, in particular analysis, synthesis, generalization, systematization and classification, as well as the Relative Importance Index to assess the priority of the author's development components. The results of the study show that cloud infrastructure protection covers at least six levels of architecture, each of which requires a separate set of control mechanisms, and the classes and models of cloud services form a different distribution of responsibility between the provider and the consumer. Modern security technologies are systematized, covering secure service networks, data categorization in transit, continuous integration pipeline certification, and AI-based vulnerability detection tools. Based on the analysis, a proprietary secure DevSecOps framework is proposed that combines behavioral anomaly assessment, automated SIEM event correlation, built-in secure development controls, project-based data leakage prevention, and cloud infrastructure hardening. An assessment of the framework components by the relative importance index showed that automated SIEM event correlation and behavioral anomaly assessment have the highest priority, while secure development controls, data leakage prevention, and infrastructure hardening play a supporting but necessary role. The practical significance of the research lies in the possibility of using the proposed framework by organizations implementing cloud services to build a holistic system for detecting and preventing cyber threats at all stages of the software development life cycle.

This article contributes in two parts. A comparative evaluation of plasma, oxy-fuel, and abrasive disc cutting methods is conducted using manufacturer data and independent technical sources, establishing the technological baseline for structural steel fabrication. An integrated production management model developed by the author at Kharkiv Stal LLC (Ukraine) over the period 2013–2025 is then presented. The model connects three components: ERP-based material reservation with three-status differentiation (available, reserved, committed), project-style order execution with stage-gated accountability, and a four-level quality inspection sequence embedded in the production cycle. Operational records from 2021–2025 document the following outcomes: order fulfillment cycle compressed from 10–14 days to 2–5 days, production delays reduced by approximately 70%, fabrication throughput increased by 30–40% without proportional workforce expansion, material preparation time shortened by 15–20%, and financial exposure to raw material price volatility decreased by 10–15%. Findings indicate that process integration methodology produces greater operational gains for resource-constrained fabricators than investment in advanced equipment without corresponding workflow coordination.

This paper expands our understanding of tattooing from the perspective of the Hlynska Tattoo Method, based on its expert concept to help us understand tattoo as a highly technical as well as a personalized and experience-driven practice. The research considers tattooing as a multidimensional practice in which individuals commemorate episodes of significance in life their own experiences as well as evoke emotions in their lives through physical form on the body. Drawing on interdisciplinary literature, the paper investigates five intersecting dimensions: life transitions; symbolic meaning; relational trust; environmental atmosphere; and emotional imprint. Although existing studies may treat these dimensions as independent; the Hlynska Tattoo Method provides a unified architecture that links technical execution in practice with psychological and emotional results. And it shows tattooing is not just a matter of putting in a bit of ink, but guided transformation, a process that depends more on the narrative the client is telling in their own head than on the artist's methodology. The relationship between the artist and client plays a role, as does the controlled environment in and around the tattoo session. This analysis helps to improve our conceptualization of tattooing as a strategically planned way of being (experiential mode of experience): namely, a process where aesthetic strategy underlies emotional transition and self-integration.

The purpose of the study is to determine the types of load on natural eyelashes during the extension procedure, to substantiate the standards for its safe implementation and to establish the risks that arise in the event of a mismatch between the parameters of artificial eyelashes and the physiological capabilities of the natural ciliary row. During the scientific study, general scientific methods of cognition were used, in particular, analysis, synthesis, generalization, systematization, comparison, classification and logical modeling. The results of the study show that during eyelash extensions a complex biomechanical load is formed, which is not limited only to the mass of artificial fiber. Gravitational, lever, aerodynamic, mechanical-contact and adhesive loads were studied, each of which affects the condition of the natural eyelash, follicle, eyelid margin and ocular surface. It is shown that exceeding the permissible length, diameter, curvature or mass of artificial eyelashes can lead to mechanical overload, traction alopecia, madarosis, irritation of the cornea and conjunctiva, as well as to the gradual depletion of the natural ciliary row. It is concluded that the safety of the procedure depends not only on the modeling technique, but also on compliance with professional, hygienic, microbiological, regulatory and clinical requirements. The author's methodology LRCA Method was separately studied, within which eyelash extension is considered as a controlled process of preserving and restoring the client's natural resource. It is shown that damage audit, determination of the initial state of the follicle, cuticle and natural row, decompression of weakened eyelashes, reconstruction and preventive safe design layer make it possible to select artificial fiber parameters in accordance with the bearing capacity of the natural eyelash. The practical significance of the study lies in the possibility of using its results to develop safe eyelash extension protocols, train masters and increase the level of consumer protection.

This paper examines how structured project management (PM) practices improve efficiency across the design–manufacture–assembly continuum of contemporary construction, with particular attention to prefabricated housing delivery. Building on a review of thirty peer-reviewed sources spanning agile and lean methodologies, Building Information Modeling (BIM), digital twins, the Internet of Things (IoT), and artificial intelligence (AI) in project controls, the paper proposes an original analytical instrument - the Modular Project Efficiency Index (MPEI) - that quantifies PM performance across three weighted dimensions: Schedule Compression, Cost Variance Control, and Coordination Density. Weights are derived through an Analytic Hierarchy Process (AHP) and stress-tested with a sensitivity analysis. Applied illustratively to a prefabricated Glulam housing delivery model, the MPEI demonstrates that integrated PM practices can compress schedules by up to 35–45% and reduce cost variance relative to conventional site-built construction. The paper concludes that PM is not a peripheral administrative function but the central mechanism through which prefabrication technologies translate into measurable efficiency gains, and it offers the MPEI as a transferable diagnostic tool for practitioners scaling modular housing delivery.

The purpose of the article is to substantiate the role of metamorphic testing and AI agents in ensuring the reliability, semantic consistency and security of corporate software based on artificial intelligence. The research process used methods of analysis and synthesis to generalize scientific approaches to testing AI systems; the comparative method was used to compare traditional QA, Metamorphic Testing and the agent approach. The results of the study showed that the reliability of corporate software based on AI cannot be ensured only by traditional QA approaches, since LLM, RAG systems, chat bots, recommendation services and AI agents operate in a non-deterministic mode and can change the answer depending on the formulation of the query. It has been established that Metamorphic Testing is an appropriate method for testing such systems, since it allows us to evaluate not a single result, but the constancy of the relationship between responses after a controlled transformation of the input data: paraphrasing, changing the format, rating scale, word order, or adding a small amount of noise. It has been proven that if the content of the query does not change, then the main fact, conclusion, class, recommendation, or logic of the response should remain stable, and their significant change indicates semantic inconsistency, the risk of hallucination, or weak robustness of the model. On this basis, the author's concept of AI-Agentic Testing is proposed, in which the AI-agent automates the generation of follow-up inputs, checking metamorphic relations, detecting unstable responses, hallucinations, logical contradictions, and potential security breaches in corporate AI systems. This approach moves QA from static test scenarios to dynamic control of semantic consistency, reliability, and security of AI solutions in a corporate environment. Its practical value lies in the fact that it can be used as a basis for testing LLM, RAG systems, AI agents and enterprise AI workflows before their integration into critical business processes.

Based on the experience of Denys Vakuliuk, owner of an automotive locksmith service, the article proposes a Five-Loop Operational Management Model that integrates five interconnected loops of his work: technological, institutional, dispatch, marketing-economic, and reputational. The technological loop covers access to the manufacturer's secure data, cloning and generating chips, and immobilizer diagnostics. The institutional loop involves legal access to dealer systems. The dispatch loop distributes service calls among technicians based on their location and workload. The marketing-economic loop manages the flow of service requests based on return on advertising investment. The reputational loop covers countering malicious attacks through customer reviews. It is shown that the competitiveness of an independent service depends on legal access to dealer systems and on the manager's ability to quickly identify weak points in the process from the initial inquiry to the completion of the job. The empirical basis is provided by this specialist's documented experience, which reveals the connections between the loops of work that are usually hidden by the division of labor among different people. The novelty of the study lies in integrating these separately-studied areas into a single decision-making framework for a small mobile service.

Most documented irrigation approaches rely on one or two measured variables to trigger events, leaving the remaining sensor data unused in the control decision. Purpose. To describe the Smart-Flow Matrix (SFM), an adaptive irrigation management framework that integrates five operational data streams within a unified decision engine, and to present resource-efficiency and yield metrics from its commercial deployment. Method. SFM was deployed in a commercial hydroponic strawberry operation (coconut coir substrate, drip fertigation, greenhouse area up to approximately 10 hectares) in Kyiv Oblast, Ukraine. SFM coordinates volumetric water content, pore-water electrical conductivity, cumulative photosynthetically active radiation, air temperature, and drainage analytics through coordinated threshold logic with seasonal parameter adjustment across three growth stages. Operational records from the SFM period were compared with records from the preceding timer-based management period in the same facility. Results. Water and fertilizer consumption decreased by approximately 45 to 50 percent relative to the timer-based baseline. Yield reached 1.7 to 1.87 kilograms per plant under commercial conditions. Drainage fraction converged to target ranges within three to four irrigation cycles following each parameter adjustment. Conclusion. SFM demonstrates that coordinated multi-parameter irrigation logic with seasonal adaptation can achieve measurable resource savings at commercial greenhouse scale without compromising yield stability.

This article describes how the director of a clinic network, without a legal background, developed and implemented the Integrated Compliance Operations Framework (ICOF), a system that integrates HIPAA and OSHA compliance checks into the facility's daily operational processes rather than isolating them in a separate audit cycle. The data used in this study came from the Zenoti medical information system covering three operational years, as well as consultation protocols from an external specialist who verified that the identified risk areas align with the current enforcement priorities of federal regulatory agencies. Key elements of the developed system include a three-tiered authorization process for patient photographic documentation, a daily checklist for regulatory compliance checks, a four-factor analytical procedure for assessing potential violations, and a staff training program featuring practical simulations of real-life scenarios. The system has been implemented in four network locations and six external facilities. The results show that integrating regulatory checks into the facility's operational rhythm reduces actual risk more effectively than the traditional model of an annual compliance audit.
