Development of a portable system for differentiated assessment of stress resistance of military personnel

Purpose of research . Professional activity of servicemen is directly related to high levels of mental and physical stress. Negative consequences of stress in servicemen are not only health problems, but also the risk of task failure. Therefore, the development of tools for assessing stress tolerance in military personnel, including in field conditions, becomes an urgent task. Existing complexes for assessing stress tolerance in servicemen, as a rule, have the following disad- vantages: large size, insufficient mobility, mandatory connection to a computer, installation of specialised software, relatively high cost, subjective nature of assessment, lack of differentiated assessment for fear and anxiety, having different morphofunctional basis. Therefore, the aim of the study is to develop a prototype of a portable system for differentiated assessment of the level of stress tolerance of military personnel. Methods . The stress tolerance assessment model is ‘predictable-unpredictable threat’. The development of the elec- tronic board was carried out using modern computer-aided design systems: NI Multisim v 14.3, Micro-Cap v 12.2.0.5, KiCad v 8.0.6, Compass-Graphic v 23, Mathcad v 15. The software component of the system is implemented using Python v 3.10 and libraries: PySide6 v 6.7.2, docx v 0.2.4, Docxcompose v 1.4.0, Cryptography v 43.0.0, SQLite v 3.47.0, Pyinstaller v 6.11.0. The housing of the portable system was modelled in Solidworks 2018 software. IDEA Maker software was used to convert the 3D model into 3D printer control commands. Results . A conceptual model of a portable system for assessing stress tolerance of military personnel based on the predictable-unpredictable threat assessment model is presented. A prototype of this system was implemented based on the conceptual model. Conclusion . The introduction of a portable system for differentiated assessment of stress tolerance into the daily prac- tice of medical and psychological service of the Armed Forces of the Russian Federation will contribute to the timely adoption of measures to preserve and improve the health of personnel, as well as to improve the efficiency of military- professional activity, and to preserve the professional health of servicemen.
