. Investigation of optimal hardware parameters and needle configurations in order to minimize microtrauma to the skin during permanent makeup//Наука онлайн: Міжнародний електронний науковий журнал - 2026. - №1. - https://nauka-online.com/publications/other/2026/1/6377-2/

Анотація: (English) 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.

. Methodological foundations of effective user research in product management//Наука онлайн: Міжнародний електронний науковий журнал - 2026. - №1. - https://nauka-online.com/publications/economy/2026/1/04-40/

Анотація: (English) Methodological approaches to user research in product management are examined in the context of early-stage startups. Drawing on practical cases and established frameworks, it is shown how the structure of interviews and question design influence the validity of insights. A significant gap is identified between users’ stated intentions and their actual behavior, often leading to false positives. It is substantiated that behavior-focused qualitative research and bias control function as decision-support mechanisms, and their application should align with the startup’s uncertainty level and resource constraints.

Creation of a global ai platform for international animal transport regulations: potential and challenges

. Creation of a global ai platform for international animal transport regulations: potential and challenges//Наука онлайн: Міжнародний електронний науковий журнал - 2026. - №1. - https://nauka-online.com/publications/information-technology/2026/1/03-45/

Анотація: (English) The study is aimed at establishing an architectural and methodological foundation for a unified global platform based on artificial intelligence technologies, intended to automate compliance in the international transportation of animals. The relevance is determined by a systemic mismatch between the rapid scaling of the Pet Travel market (expected volume — $5.3 billion by 2034) and the inertia of the regulatory infrastructure, which relies on fragmented national prescriptions and heterogeneous control procedures. The objective is to transition from the dominant document-centric paradigm to a data-centric ecosystem in which regulatory requirements and logistical events are represented as formalized entities and relationships governed by knowledge graphs and large language models (LLM). The methodological framework is constructed as a hybrid: a system analysis of regulatory requirements of more than 60 states was conducted, econometric modeling tools were applied to identify factors affecting the probability of refusal of transport, and a synthesis of practice-oriented cases reflecting real scenarios of veterinary and transport support was performed. The results obtained show that the implementation of semantic algorithms for data verification and reconciliation increases the completeness and consistency of compliance checks, which makes it possible to reduce the share of transport refusals by 40–50% and simultaneously decrease biosecurity risks through the early detection of regulatory inconsistencies and potentially dangerous deviations in the chain of supporting information. The presented conclusions are relevant for the design and implementation of LegalTech solutions, the activities of veterinary services and logistics operators, as well as for the professional community associated with ensuring animal protection.

. Clinical protocols for aesthetic rehabilitation of the nail apparatus in patients with diabetes mellitus: a comparative analysis of wet and dry hardware treatment technologies//Наука онлайн: Міжнародний електронний науковий журнал - 2026. - №1. - https://nauka-online.com/publications/medicine/2026/1/02-48/

Анотація: (English) In the context of the global increase in diabetes mellitus, which by 2024 has affected 589 million people, ensuring the safety of aesthetic procedures becomes a priority task in podology and dermatology. The present study is devoted to the substantiation of standards for safe manicure in patients with endocrinological disorders who have a high risk of injury due to diabetic neuropathy and angiopathy. The aim of the work is a comparative analysis of the effectiveness and safety of dry and wet hardware technologies for nail plate treatment. The research methodology is based on a systematic literature review, analysis of ADA and IWGDF clinical guidelines, as well as a retrospective case study of the author’s practice. The results demonstrate that the use of wet spray technologies makes it possible to maintain the temperature in the treatment area below the protein coagulation threshold (<40°C) and reduces the concentration of respirable bioaerosol by 90%, which is critically important for the prevention of infectious complications. In conclusion, it is stated that there is a need to introduce hydro-burring as the most appropriate option for diabetic patients, excluding aggressive cuticle removal. The information contained in this article will be of interest to practicing podologists, nail service specialists, dermatologists, and endocrinologists seeking to improve patients’ quality of life.

. Strategic model for integration of PV generation and hydro-storage in the Southern Nevada power system: an economic rational case for us energy security//Наука онлайн: Міжнародний електронний науковий журнал - 2026. - №1. - https://nauka-online.com/publications/technical-sciences/2026/1/01-50/

Анотація: (English) In today's energy system, where renewable energy is actively developing, Energy Storage Systems (ESS) are becoming particularly important. A promising direction for ensuring the reliable and uninterrupted operation of energy systems in the United States (US) is modern approaches to the integration of solar energy generation systems (PV generation) and pumped storage power plants. The study analyzed the technical characteristics of a strategic integration model, its advantages, and potential limitations using the example of Southern Nevada. The article presents key concepts of the economic rationale for integrating PV generation and pumped storage power plants for US energy security. It is argued that the combination of pumped storage and PV generation can effectively smooth out fluctuations in renewable energy generation and cover peak loads, increasing the flexibility and resilience of the power system.
