Annotation: Psychological barriers and compositional technical solutions – as an inevitable basic pushing basis for the creation of software products – equivalent to complex integrative inventions – become the main topic of brainstorming in the context of creating smart technologies; The emergence of information technologies and a sharp reduction in the time cycle intended for the development and transformation of an inventive idea into a truly necessary, marketable and marketable product, the complication of the technical and technological components of new products, causing a proportional increase in the cost of manufacturing prototypes of the invented product and their testing, force us to consider in a completely new way the possibility of creating technical solutions with auxiliary innovative functions. Now, if an inventor wants his innovative ideas to be used, he must be more versatile and must possess not only the technique of foresight, intuition and, to a certain extent, a developed imagination, but also be a practically multidisciplinary specialist, at least feeling and (better if) well understanding the commercial and consumer demands of the market, regardless of stereotypes and the psychological barriers associated with them.

Annotation: This paper studies the implementation of artificial intelligence (AI) in creating personalized nail services. The promotion presents an analysis of contemporary technologies-namely, machine learning and natural language processing in the development of an exclusive pattern of nail designs that will be based on the personal preferences of a particular client. An account is given of how data can be collected through social networks and survey platforms, the following analysis of which supports the establishment of a custom solution for the clientele. An overview of existing technological platforms in the beauty industry used to achieve similar goals is presented with an eye to prospects for this sector’s development, thereby including, among other things, 3D printing and augmented reality technologies. The paper also contains the major barriers of the proposed innovations' integration into practice. The study brings out the potential application of AI as a tool to improve service quality and customer satisfaction in the beauty sector. This publication will capture the attention of beauty industry professionals: manicurists and owners of salons incorporating innovative methodologies into their practice. It can also prove handy for researchers and developers within the realm of artificial intelligence and machine learning, explicitly for those working on applications in cosmetology. Moreover, this content may draw the interests of marketers and analysts - those who explore consumer trends and the influence of social networks on consumer behavior, now within the aesthetic services arena.

Annotation: This article investigates the role of executive leadership in transforming financial management practices in global organizations, with a specific focus on the United States and Europe. Drawing on recent academic literature and authoritative consulting reports from the past five years, the study examines how top executives—particularly Chief Financial Officers—drive change through clear vision setting, strategic alignment, technology adoption, process reengineering, and talent development. The comparative analysis highlights common trends, such as a shift toward digital and data-driven financial functions, as well as regional differences in the urgency and methods of transformation. The findings indicate that effective executive leadership is pivotal for overcoming resistance to change, ensuring regulatory compliance, and fostering a culture of continuous improvement. These insights provide both theoretical contributions and practical recommendations for organizations aiming to modernize their financial management in today’s complex business environment.

Annotation: As practice has shown, piezoelectric motors working on the basis of reverse piezoelectric effect principles can become the foundation for the latest automation and precision mechanics systems, as well as innovative lighting technology. The main interest of designers is focused on the possibility of building systems and configurations based on the reverse piezoelectric effect, related to precision and compact stepper motor systems. As the requirements for accuracy increase and the weight of such motors is reduced, including by decreasing their size, more solutions are proposed for the construction of elements and structures of these motors based on the complex use of special composite materials.
