. Comparison of the effectiveness of hardware methods in combating cellulite, improving skin tone and body contours//Science online: International Scientific e-zine - 2025. - №12. - https://nauka-online.com/en/publications/other/2025/12/06-33/

Annotation: This article reviews various hardware methods used to treat cellulite, improve skin tone and model body contours. The main goal of the work was to show how these approaches differ from each other and what clinical results can be expected when using them, based on the analysis of already published studies. Standard scientific approaches were used in the work - analysis and generalization of data, comparison of results and systematization of information from various sources. The results obtained indicate that hardware methods for correcting cellulite differ significantly both in terms of mechanisms of action and in the severity and duration of the effect. Radiofrequency therapy mainly affects the dermis, promoting collagen remodeling and increasing skin elasticity, but its ability to eliminate cellulite depressions is usually limited. Extracorporeal shock wave therapy demonstrates a noticeable reduction in the severity of cellulite, which is associated with improved microcirculation and activation of regenerative processes in tissues, although the optimal regimens for its use remain the subject of further research. Mechanical vacuum-assisted therapy provides rapid visual improvement by reducing swelling and congestion, but this effect is usually temporary and requires regular repetition of procedures. Laser techniques, in turn, have proven to be a heterogeneous group: low-intensity laser therapy gives conflicting results, while laser-assisted subcision demonstrates a more stable improvement in skin structure and a reduction in cellulite, especially in the thighs and buttocks. Vibration exercises mainly affect muscle activity and body composition, so it is advisable to consider them as an auxiliary element in complex programs, and not as an independent method of cellulite correction. Subcision, although it is the most invasive approach, shows the most pronounced effect in cases of deep cellulite indentations, since it directly eliminates the mechanical factors of their formation. The practical significance of the analysis is that it allows a more reasoned approach to the choice of hardware techniques, adapting the treatment tactics to the type of cellulite, skin condition and expected clinical result, which is key for individualized correction.

Comparative analysis of deterministic and probabilistic methods for verifying architectural constraints in microservice systems

. Comparative analysis of deterministic and probabilistic methods for verifying architectural constraints in microservice systems//Science online: International Scientific e-zine - 2025. - №12. - https://nauka-online.com/en/publications/technical-sciences/2025/12/05-37/

Annotation: The article addresses the challenge of automating architectural quality control in microservice systems designed using Domain-Driven Design methodology. A comparative analysis of the effectiveness of deterministic methods and probabilistic methods was conducted. Using a simulated e-commerce system with a controlled set of defects, a quantitative assessment of Precision and Recall metrics was performed for both approaches. The experiment confirmed that deterministic methods ensure absolute precision in detecting structural boundary violations but exhibit "semantic blindness" regarding complex DDD patterns. Conversely, probabilistic methods demonstrated high effectiveness in identifying semantic defects, such as anemic domain models and context leakage, with an acceptable level of false positives. Based on the results, the necessity of implementing a hybrid verification strategy is substantiated, where static analysis acts as a rigid gatekeeper in CI/CD pipelines, while AI tools serve as an intelligent architect's assistant.

Annotation: The relevance of the study is determined by the need to preserve Ukrainian cultural identity within the urban space, where floristics is viewed as a means of representing national symbols and cultural codes in the city’s visual environment. The purpose of the article is to define the theoretical foundations and practical possibilities of using floristics as a tool for expressing Ukrainian identity and integrating it into contemporary urban design concepts. The methodology is based on systemic, cultural, and semiotic approaches employing methods of analysis, synthesis, and case analysis of urban practices. The results demonstrated that floristics performs aesthetic, semiotic, sociocultural, ecological, and communicative functions, shaping a recognizable Ukrainian cultural landscape. The conclusions confirm that floristics can harmonize natural and social environments while strengthening cultural identity.

Аналіз токсикологічних ризиків хімічних компонентів у матеріалах для нарощування вій та фарбування брів

. Аналіз токсикологічних ризиків хімічних компонентів у матеріалах для нарощування вій та фарбування брів//Science online: International Scientific e-zine - 2021. - №9. - https://nauka-online.com/en/publications/chemistry/2021/9/18-11/

Annotation: (Українська) Мета дослідження полягає у визначенні токсикологічних характеристик хімічних компонентів, що входять до складу косметичних матеріалів для декоративного оформлення очей і брів, та оцінюванні ризиків для здоров’я споживачів і працівників індустрії краси. Методи. Проведено комплексний аналіз наукової літератури, систематизацію даних про хімічний склад косметичних продуктів, що використовуються в Україні, та оцінювання їхнього токсикологічного профілю. Досліджено дві групи клеїв для нарощування вій: гіпоалергенні продукти (Vivienne Paris, Vivienne Expert, Vivienne Miami, Lex Lux) та посилені клеї (Lamour Speed, Nagaraku Premium Extra Strong, Lamour Elegant, Nagaraku Clear Glue). Додатково проаналізовано барвники для брів та вій (Lash Secret, RefectoCil, ZOLA, Levissime, Elan), препарати для ламінування (Lash Secret, InLei, Elan) та пігменти для перманентного макіяжу (Leader by Druzhinina, Tinel, Perma Blend). Результати. Встановлено, що основними токсикологічно значущими сполуками у досліджуваних продуктах є цианоакрилати (здатні вивільняти формальдегід), парафенілендіамін, парабени та ароматичні речовини. Цианоакрилати, що становлять базовий компонент клеїв для нарощування вій, спричиняють алергічний контактний дерматит, токсичний кон’юнктивіт та респіраторні реакції. Парафенілендіамін у барвниках асоціюється з високою частотою сенсибілізації та розвитком контактної алергії. Ідентифіковано специфічні професійні ризики для косметологів, зумовлені систематичною експозицією до летких сполук під час виконання процедур. Висновки. Комплексний аналіз токсикологічних характеристик косметичних матеріалів для декоративного оформлення очей і брів виявив значні ризики для здоров’я, що потребує розроблення науково обґрунтованих рекомендацій щодо безпечного використання цих продуктів та удосконалення регуляторних норм у косметичній індустрії.
