Annotation: This paper analyzes the phenomenon of clean beauty and its impact on the consumer behavior of women over 35 years of age. The relevance of the study is justified by the rapid growth of the clean cosmetics segment in the market and the shift of mature consumers’ value orientations toward conscious consumption and holistic healthcare. The aim of the research is to identify and analyze the main catalysts shaping the purchasing patterns of women aged 35+, and to substantiate a synergistic model that combines external cosmetic practices with internal nutraceutical interventions. The methodology includes a systematic analysis of specialized scientific publications on consumer behavior, dermatocosmetology, and functional nutrition science, as well as the processing of empirical data obtained in the course of practical nutritional work. The results indicate that for the target group clean beauty is not merely a marketing category but responds to the demand for safety, proven efficacy, and a harmonious unity of external appearance and health status. A conceptual model is described, demonstrating that maximum fulfillment of the audience’s needs is achieved by integrating clean cosmetics with personalized nutraceutical programs aimed at correcting metabolic and hormonal imbalances. The scientific novelty of the study lies in the conceptualization of the clean beauty trend as an entry point into a comprehensive health management system for women of mature age. The practical significance of the results lies in their applicability for cosmetic brand marketers, preventive medicine specialists, nutritionists, and cosmetologists.

Annotation: The study presents a comprehensive analysis of factors determining the seasonal fluctuations in demand for services of fishing tourist centers. The relevance of the work is defined by the growing role of domestic tourism and the necessity of strengthening the economic sustainability of enterprises in the recreational fishing sector, which face uneven workload throughout the calendar year. The objective of the study is to conduct a comprehensive analysis of factors defining seasonal attendance fluctuations at fishing tourist centers and to identify key determinants of demand in different periods of the year. The methodological framework includes a systematic review of specialized scientific publications, statistical analysis of consumer behavior data and content analysis of applied marketing strategies. According to the results, biological cycles (spawning events, migration processes) and climatic conditions are the primary drivers of peak attendance seasons. At the same time, the growing importance of service diversification and digital marketing contributes to attracting tourists in the off-season. As a result, an integrated model for managing seasonal demand is described, based on a combination of operational, pricing and communication tools. The obtained conclusions have practical significance for managers of fishing tourist centers, tourism development specialists and regional authorities responsible for planning and developing tourist infrastructure.

Annotation: This article presents a theoretical analysis of the parameters of friction discs used in high-performance automotive clutches, with a focus on the interrelation between chemical composition, geometric characteristics, and thermal load. The study is based on an interdisciplinary approach integrating tribology, materials science, and thermal mechanics. Particular attention is given to the interpretation and comparison of published empirical data reflecting the influence of key elements in friction composites on the coefficient of friction and thermal stability. The geometric and operational parameters of clutches under racing conditions are examined, including high-frequency engagement cycles, limited cooling capacity, and localized thermal gradients in multilayer stacks. A comparative analysis of the thermal behavior of carbon-ceramic and cast-steel discs is conducted, justifying the applicability of each type under specific loading and thermal saturation modes. The study establishes computational relationships between material composition, heat resistance, clutch configuration, and critical slip conditions, enabling the formulation of rational criteria for selecting materials and geometries suitable for clutches operating under extreme conditions. The proposed approach can be integrated into engineering procedures for component selection and evaluation using digital computer-aided design tools. This paper will be of interest to design engineers, powertrain specialists, tribology and thermal analysis researchers, and developers of CAD/CAE systems for frictional components.
