This thesis covers the pedagogical and psychological foundations of the formation of vocal performance skills in primary school students. The criteria for selecting age-appropriate vocal exercises for children, developing musical hearing, breathing techniques, and expressive singing skills are analyzed on a scientific basis. The main factors influencing the formation of vocal performance are also studied - teacher skills, musical environment, methodological approaches in the lesson process, and the role of individual approaches. According to the results of the study, a systematic, step-by-step approach is important for the development of vocal abilities in primary school students.

Chronic kidney disease (CKD) is a prevalent and life-threatening condition that significantly impacts the health of individuals. As CKD progresses to end-stage renal disease (ESRD), patients are often required to undergo renal replacement therapy (RRT), such as hemodialysis (HD), to sustain life. The advent of modern dialysis methods has led to a substantial increase in life expectancy for ESRD patients, extending it by an average of 10–12 years. However, despite the improvement in medical outcomes, the prospect of lifelong dialysis treatment presents various psychological and social challenges for patients. Dialysis is often perceived as the end of life by patients, leading to significant emotional distress.

A number of standards and recommendations have been adopted to regulate the “compliance-control” system in the field of combating corruption in the private sector from an international legal perspective. These standards focus primarily on the timely identification of corruption risks in the private sector, and then on the activities of state agencies and organizations, their prevention, ensuring openness and transparency, and timely elimination of corruption-related offenses by improving internal departmental control mechanisms.

Etymological research has long been the focus of particular attention among linguists. Such studies involve the analysis of a word’s linguistic affiliation, the language in which it first appeared during the period of its early usage, its original meaning, as well as the specific features of its semantic development. This article emphasizes the necessity of lexicographic research in the etymological analysis of the terms “irrigation” and “melioration”. Special importance is attached to explanatory and etymological dictionaries, language corpora, and thesauruses in this context.

Indoor radon exposure is a major environmental health issue, yet it often goes unnoticed due to the gas’s undetectable nature — it is invisible, odorless, and tasteless. Radon originates from the natural decay of uranium in soil and rocks and can enter buildings through foundations and construction materials. Prolonged inhalation of radon is a well-established risk factor for lung cancer and has been identified by the World Health Organization (WHO) as the second most common cause of the disease globally, after tobacco use.

This study investigates the role of advanced MRI techniques in optimizing surgical strategies for pediatric brain tumors located in functionally significant areas. A total of 80–120 children aged 0–18 years were included, with 40 patients undergoing MRI, MR-tractography, and functional MRI, while 40 patients formed the control group without advanced imaging. The research focuses on improving surgical planning, minimizing neurological damage, and enhancing quality of life. Clinical outcomes, surgical radicality, and neurological and neuropsychological statuses were evaluated. Results indicate that image-guided approaches significantly improve surgical precision and reduce postoperative complications, especially in complex tumor localizations near eloquent brain regions.

The process of globalization has brought unprecedented challenges to humanity's relationship with the natural environment.

Изучение особенностей клиники, диагностики и лечения различных соматических болезней при их сочетании остается одной из актуальных проблем клиники внутренних болезней. Наличие у большинства терапевтических больных нескольких заболеваний вызывает немалые трудности как в установлении диагноза, так и в определении тактики их лечения. В значительной степени это относится к ишемической болезни сердца (ИБС) и хронической обструктивной болезни легких (ХОБЛ), которые в настоящее время наряду с артериальной гипертензией и сахарным диабетом являются ведущими хроническими заболеваниями у больных старших возрастных групп и занимают лидирующее положение среди причин нетрудоспособности, инвалидности и преждевременной смертности [2, 12].

This study evaluates the effectiveness of an individualized approach to Nd:YAG laser capsulotomy in pediatric patients with secondary cataracts. A total of 135 children (270 eyes), aged 8 months to 13 years (mean age: 6.1 ± 2.3 years), were examined after previous cataract surgery. Laser parameters were selected based on posterior capsule fibrosis density, age, and intraocular lens (IOL) type. At the 12-month follow-up, 89.6% (242 eyes) retained a clear visual axis and 83.3% (225 eyes) showed improvement by at least 2 Snellen lines. Complication rate was reduced to 7.8%. The individualized method enhances safety and visual outcomes in pediatric laser treatment.
