. Project-based learning in secondary school humanities: pedagogical reflection, learner autonomy, and deep learning//Science online: International Scientific e-zine - 2023. - №4. - https://nauka-online.com/en/publications/pedagogy/2023/4/12-21/

Annotation: Contemporary secondary education increasingly emphasises the development of students' capacity for meaningful learning, critical information analysis, and independent knowledge construction. This article examines project-based learning (PBL) as a pedagogical approach with significant potential for fostering learner autonomy, analytical thinking, and metacognitive skills within humanities subjects at the secondary school level. Drawing on a review of research in project-based and problem-oriented learning, as well as reflective analysis of pedagogical practice, the paper describes a staged model for organising project work within classroom time. Particular attention is given to the teacher's role as facilitator and to the significance of formative assessment and structured reflection throughout the learning process. The findings indicate that PBL, when implemented as a sequential, supported, and reflective process, promotes the formation of durable learning strategies, the development of student independence, and deeper engagement with humanities content. The practical contribution of the article lies in a step-by-step pedagogical model grounded in teacher reflection and adaptable to standard school curricula.

. Протоколи регенерації нігтьової пластини після використання акрилових систем//Science online: International Scientific e-zine - 2025. - №6. - https://nauka-online.com/en/publications/other/2025/6/08-25/

Annotation: (Українська) Акрилові нігті захопили косметичний ринок два десятиліття тому, але питання про те, що вони роблять з природною нігтьовою пластиною, довго нікого особливо не цікавило. Ця робота розбирає механізми пошкодження нігтів після акрилового нарощування та збирає докупи протоколи відновлення на основі клінічних даних 2017-2024 років. Виявилося: основна біда йде від механічного спилювання під час підготовки та зняття, хімічного протравлювання кислотними праймерами, зневоднення через розчинники та руйнування ліпідного захисту. Клінічно це виглядає як витончення пластини на 20-35%, розшарування, поздовжні тріщини, підвищена ламкість. Відновлення базується на припиненні травмування, поверненні вологи та ліпідів, застосуванні кератинових засобів та стимуляції зони росту. Повна регенерація займає 4-6 місяців за умови повної відмови від акрилу. Профілактика включає низькокислотні праймери, м'яку обробку поверхні, делікатне зняття та обов'язкові перерви між процедурами.

. Investigation of optimal hardware parameters and needle configurations in order to minimize microtrauma to the skin during permanent makeup//Science online: International Scientific e-zine - 2026. - №1. - https://nauka-online.com/en/publications/other/2026/1/6377-2/

Annotation: Permanent makeup is one of the most sought-after cosmetic procedures. However, despite its popularity, there is a problem of skin microtrauma, which can occur due to incorrect choice of device and needle parameters. In this article, we will look at the key factors affecting the safety and effectiveness of permanent makeup. These factors include the diameter and configuration of the needles, the length of their tips, as well as the depth and rate of penetration of the pigment. Assessing the effect of these parameters on the skin and ways to optimize them will help minimize tissue damage and improve the safety of procedures. The article will provide recommendations for improving permanent makeup technologies, including the use of more accurate devices, optimizing needles, and developing better pigments.

Annotation: The article discusses the reasons why unwanted color changes may occur after the permanent eyebrow makeup procedure, and suggests measures to prevent such changes. The relevance of this topic is due to the high risk of changing the original shade of the pigment, which may negatively affect aesthetic perception and require additional procedures. The article discusses the main factors contributing to color shifts the chemical composition of the pigment, its interaction with the skin and external conditions, including ultraviolet radiation. To minimize the risks, recommendations are offered on the choice of pigment, the technique of its introduction, as well as correction and care methods that will help preserve the initial effect and prolong the beauty of your eyebrows.
