The article examines the peculiarities of nuclear blackmail as a tool of Russia’s foreign policy in the post-truth era and the threat this poses to Ukraine and the international community. It also analyzes the Russian Federation’s legal and regulatory framework in the nuclear sphere, in particular the latest official documents of 2024-2025, which significantly expanded the list of grounds for the use of tactical nuclear weapons – a move that directly contradicts the international obligations of the USSR/Russia under the Treaty on the Non-Proliferation of Nuclear Weapons.

In the design of modern mission-critical systems, the system engineering stage of design requires not only ensuring a high level of reliability through the use of various types of redundancy, but also taking into account the impact of maintenance during the operational stage on system safety indicators. It is important to take into account not only the availability of repairs and their parameters, but also the sequence of actions taken by the repair team to eliminate malfunctions, i.e., the type of maintenance strategy.

The article analyzes the legal principles and practical aspects of detecting, recording and investigating violations of legislative requirements in the field of public catering, and also determines the role of forensic research in ensuring the objectivity and completeness of the evidence base in proceedings related to violations in the work of public catering establishments.

The main principles of the system of team interaction of enterprise personnel in modern conditions are determined and recommendations for its improvement are provided.

The authors argue that the impact of globalisation on the transformation of traditional threats to the international community caused the emergence of new asymmetric threats. The newest asymmetric threats originate from "weak" states or groups, which, despite lacking military superiority, can cause significant damage to stronger international actors in various ways. The article analyses the main characteristics of asymmetric threats, including their intensity, probability, and timeframe, which allow weaker actors to inflict damage.

This article analyzes the possibilities for exercising the right to freedom of thought, conscience, and religion in Ukraine during martial law. It emphasizes that although Ukraine is a secular state with constitutionally enshrined separation of church and state, this does not negate its obligations to ensure this right. On the contrary, the secular nature of the state requires a set of legal and organizational measures to guarantee everyone’s right to freedom of belief.

The article clarifies that the modern educational environment is one of the main components on which the policy of an educational institution should be based in order to provide the necessary conditions, means, and technologies for teaching students, educators, and parents, both within and outside the educational institution.

This paper proposes an enhanced model of Host Intrusion Detection Systems (HIDS) adapted for Linux- based Network Operating Systems (NOS), specifically SONiC. The SONiC architecture has been analyzed to identify intrusion-sensitive components, including telemetry data, container logs, and inter-container communications. A machine learning-based HIDS profile has been introduced to detect anomalies within containerized services and network modules. Signature-based, anomaly-based, and hybrid-based detection approaches have been classified with consideration of NOS-specific traits.

Safety Critical Systems (SCS) play a key role in critical areas of activity where high safety, reliability and continuity of operations are required. Such systems include military, space, energy, aviation, medical and transportation complexes that operate in extreme conditions and must perform their functions regardless of external and internal influences.

The modern development of urban environments requires the creation of comfortable, safe, and architecturally thoughtful spaces for children. Children's amusement parks play a crucial role in urban settings, as they combine functionality, aesthetics, and integration with the natural landscape.
