Secondly, building the concept of the security structure of a cyber-physical system based on the Zero Trust Security approach. Creation of a new secure load transfer structure based on the semiotic approach. \u0000Investigated problem: Information system security problems continue to cause significant costs and damage to organizations. Sustainability requires comprehensive and integrated security platforms that reach customers, whether they work at headquarters, in a branch office, or individually from random touchpoints. \u0000The main scientific results: the concept of a structured protection system with the Zero Trust Security approach has been developed. The structure of the semiotic analysis of the segmentation of the transmitted load on the blocks is proposed. Blocks by signs are subjected to individual analysis. According to the features, the blocks are transformed by the selected representation into an object/groups of objects. Groups for transmission in the load are tagged, have different coding severity (depth), depending on the risk assessment. Groups are transmitted through the network in different ways (paths) – VPN (different ESP), unencrypted tunnel, open access, etc. \u0000This solution improves the throughput of malicious load analysis prior to transmission. The performance overhead for encoding/decoding the load and encapsulating/de-encapsulating during transmission is reduced. The transmission bandwidth is increased. \u0000The area of practical use of the research results: businesses requiring secure access to on-premise resources and mission-critical cloud environments. Organizations using employees in distributed networks. Specialists in the deployment and analysis of the protection of cyber-physical systems. \u0000Innovative technological product: The semiotic security concept extends the zero-trust security model, which focuses on protecting network traffic within and between organizations. This concept uses load traffic segmentation, which combines an advanced analysis and transfer load transformation framework. \u0000This concept provides for integration with other cybersecurity technologies such as endpoint discovery and response (EDR) and security information and event management (SIEM) to provide a more comprehensive security solution. \u0000This solution improves the throughput of malicious load analysis prior to transmission.

In such household combined appliances, the heat released during the implementation of the refrigeration cycle is not immediately removed to the environment, but is transferred to a special heating chamber, while the temperature in the volume of the heating chamber is maintained higher than the air temperature in the room.

The paper looks into Ukrainian DU technology transfer (TT) through a prism of historical premises.

Needless to say, that a technology transfer is a complicated, multi-leveled and multi-players process being impacted and followed with few factors and historically pre-set conditions that constrain its success or failure at the end.
