Annotation: At most large domestic enterprises, the HR department and the payroll department report to different managers, which creates a gap between HR decisions and their reflection in payroll calculations and increases the risks during inspections by regulatory authorities. The article examines the organizational and technological conditions under which a personnel evaluation system becomes an effective tool for enterprise management. Based on the author's management experience at three large enterprises – SE “Pivdennyi Sea Port Administration,” OilGasChem Service (OGC Service), and Lukoil Technologies Services Ukraine – a comparative analysis of personnel evaluation methods is conducted, the role of personnel commissions is characterized, and the author's HR-ERP system, implemented from scratch at two enterprises (OilGasChem Service (OGC Service) and Lukoil Technologies Services Ukraine), is described. It was found that combining a competency model, KPI approach, and performance review provides better management results than using each method separately. It was shown that combining the functions of the HR manager and the head of the payroll department in one position significantly reduces the number of calculation errors and ensures end-to-end consistency of personnel documentation and reporting. The scientific novelty is the concept of “live calculation” – an architectural solution in which any change in personnel status automatically and without delay recalculates accruals, which fundamentally distinguishes the system from standard solutions based on the paradigm of closing the calculation month.

Annotation: This publication is dedicated to the quantitative evaluation and mathematical substantiation of the economic efficacy of the proprietary VFRP (Visual Finish-Result Planning) technology within the context of retail chain deployment. The study is grounded in a comprehensive analysis of a professional project portfolio spanning from 2007 to 2022, encompassing 108 completed fit-out projects (n = 108). The methodology demonstrates no statistically significant schedule deviation within the observed sample, while ensuring high operational stability during the simultaneous management of up to 17-20 assets. The author proposes an innovative management system predicated on backward scheduling mechanisms and the visualization of the target state as a “Single source of truth”. The study presents a mathematical model for the minimization of economic attrition, encompassing the formalization of empty rent expenditures, opportunity costs and rework expenses. Particular emphasis is placed on the variable frequency response mechanism, which ensures the exponential decay of temporal errors through non-linear control reinforcement at critical interaction nodes. Empirical verification across international chains confirms that the VFRP technology guarantees zero schedule variance in 95% of implementation cases. The research findings position VFRP as a fundamental investment risk hedging mechanism that ensures the stabilization of operational profit from the inaugural day of the lease.

Annotation: Massage therapy is widely used to relieve muscle tension and improve circulation, yet the physiological mechanisms responsible for these effects remain fragmented across disciplines. This study constructs a hierarchical model of how massage acts on muscle tissue, the vascular system, and the nervous system at different levels of biological organization. Through a systematic review of 20 peer-reviewed sources, including shear-wave elastography studies, Doppler ultrasound investigations, near-infrared spectroscopy measurements, and molecular-level biopsy analyses published between 1990 and 2024, the study identifies four distinct levels at which massage exerts its effects: the tissue level (viscoelastic deformation and fascial remodeling), the macrovascular level (venous return facilitation without significant arterial flow increase), the microcirculatory level (capillary perfusion enhancement and lymphatic drainage), and the neuroreflex level (spinal, brainstem, and cortical modulation of muscle tone). A notable finding is that massage does not increase arterial blood flow to muscles, as demonstrated by Shoemaker et al. [8] and confirmed by Wiltshire et al. [10], contradicting a widely held assumption. At the molecular level, Crane et al. [1] showed that massage attenuates NF-κB signaling and stimulates mitochondrial biogenesis via PGC-1α activation. The study proposes three original analytical frameworks: a three-stage temporal model of muscle relaxation based on shear-wave elastography data [4; 6; 7], a concept of differentiated vascular response synthesizing Doppler and near-infrared evidence [8–12], and a comparative effectiveness matrix evaluating six massage techniques across six physiological parameters.

Annotation: This study explores the psychosocial mechanisms within the athlete-mentor dyad, aiming to define how systemic martial arts training fosters discipline, reduces deviant behavior and cultivates leadership traits among youth. The research employs a qualitative interdisciplinary approach, integrating sports pedagogy, behavioral psychology and sociological analysis. A system-structural analysis was utilized to model the discipline internalization loop. The empirical base includes a retrospective review of longitudinal case studies of high-performance athletes in boxing and wrestling over a 5-year period, alongside a comparative analysis of global and regional (Ukrainian) youth sports participation trends from 2005 to 2025. The findings indicate that the mentor serves as the primary architect of a hidden curriculum, where the internalization of rigid ethical codes acts as a predictor of both elite competitive success and social adaptation. The application of stress inoculation training demonstrated a strong correlation between the regulation of acute physiological stress and the development of adaptive tactical intelligence. A significant paradigmatic shift was observed in the Ukrainian cohort, where motivation for athletic engagement has transitioned from aesthetic aspirations to functional fortitude as a mechanism of national resilience. The study validates the athlete-mentor as an architect framework, concluding that the integration of hierarchical mimesis and progressive psychosocial overload effectively transforms raw aggression into social responsibility. Martial arts training is thus positioned as a critical institution for developing socially integrated leaders capable of operating under conditions of chronic external stress.
