    Improvement of digital device for suppression of erroneous request by lateral petals of the antenna of air traffic control systems
    (Khmelnytskyi National University, 2022) Hovorushchenko, T.; Yanovitskiy, A.
    This article considers the expansion of the capabilities of digital devices of three-pulse suppression of the request of aircraft responders with side petals in terms of increasing the accuracy of measuring the azimuth of flight of aircraft. In existing devices, the response of aircraft responders is carried out at the time of the boundary crossing by the aircraft of the frequency pattern of the antenna. The directional pattern of the radar systems of the main petal has an angle of 2o-4o in the horizontal plane depending on the type of radar system and the request period of terrestrial radar stations is 500 Hz, and the antenna rotation speed is 10 rpm and the distance between pulses P1 and P3 is 14 μs. The time the aircraft is within the directional pattern of the main petal will be requested 17 times and the same number of responses, which in turn leads to ambiguity in fixing the definition of the aircraft in azimuth, especially over long distances. The response of the aircraft respondent to the request will be answered when approaching the middle of the directional pattern of the antenna of the main lobe, where the highest power of the emitted signal, which will significantly reduce the error of determining the aircraft by azimuth.

    Method of assessing the reputation of a medical institution (as a miner of blockchain)
    (Хмельницький національний університет, 2022) Hovorushchenko, T.; Osyadlyi, V.
    The healthcare sector in Ukraine has long been in need of change, and the many opportunities of blockchaintechnology can help it lead the transformation of this sector and ensure compliance with the requirements of efficiency, safety, noveltyand economic benefits.Blockchain will transform medical enterprises and improve the quality of service, allowing new ecosystems and new business models to develop. Healthcare information stored in the blockchain can change the way clinical information is stored, as wellas how information is shared in the organization, with healthcare partners,payers and, most importantly, patients. Blockchain decentralizes medical information by increasing the availability, efficiency, transparency, and credibility of data, but also requires careful planning to maximize the benefits it brings. With the help ofthe blockchain, users can store important medical data, the authenticity of which can be verified if there is a suspicion of forgery. In addition, cryptographic algorithms can be used to ensure the confidentiality of medical data (for example, an attackerwill not be able to read the text if he stole data). Thus, the current challenge is the need to manage medical data based on blockchain technologies.The reputation of the medical institution (as a blockchain miner) is an important indicator, as the blocks are recorded by verified pre-selected validators and are in fact moderators of the system. It is to determine such validators that the value is not the number of tokens, but reputation, ie the blockchain according to a certain algorithm, taking into account the reputation, choosesa validator who will write the next block. Reputation grows with active life in the blockchain ecosystem and interaction with other participants. The better the reputation -the greater the chance of creating the next block. Therefore, the method of assessing the reputation of a medical institution (as a miner of blockchain), which allows to calculate and assess the reputation of a medical institution, was further developed in the article.Experiments on blockchain-based medical data management using the developed method of assessing the reputation of a medical institution (as a blockchain miner) -experiments to assess the reputation of a medical institution (for example, two different family medicine clinics) -as a blockchain miner.

    Neural-network model of software quality prediction based on quality attributes
    (Khmelnytskyi National University, 2022) Lebiga, M.; Hovorushchenko, T.; Kapustian, M.
    The paper proposes a neural-network model of software quality prediction based on quality attributes. The proposed model differs from the known models, because it provides considering the importance of each quality attribute and their interaction within each software quality characteristic. The artificial neural network (ANN) outputs correspond to the values of software quality characteristics (functional suitability, performance efficiency, usability, reliability, compatibility, security, maintainability, portability). The artificial neural network (ANN) outputs make it possible assessing the total impact of quality attributes on software quality characteristics.

    Overview of the methods and tools for situation identification and decision-making support in the cyberphysical system «Smart House»
    (Хмельницький національний університет, 2022) Hovorushchenko, T.; Aleksov, S.; Talapchuk, S.; Shpylyuk, O.; Magdin, V.
    The technology of a smart house is mostly understood as a system that combines a number of subsystems that provide comfortable living conditions for residents in the room and make it possible to significantly reduce energy costs. A house is called smart if it has a certain computer or control system for managing engineering equipment. "Smart House" should be designed so that all services can be integrated with each other with minimal costs (in terms of finances, time and effort), and their maintenance would be organized in an optimal way.The "Smart House" system should competently allocate resources, reduce operating costs and provide a clear control and management interface. Such an intelligent system should be able to recognize specific planned and emergency situations occurring in the home and respond to them (make decisions) in accordance with the given program. Therefore, today the urgent task is to recognize the situation and support decision-making in the "Smart House" cyber-physical system.The conducted overview of methods and tools for situation identification and decision-making support in the "Smart House" cyber-physical system showed that: in existing solutions, situation recognition occurs only for one of the groups of the system of managed housing functions or does not occur at all; existing solutions provide decision-making support for only one ofthe groups of the system of managed housing functions or do not provide it at all; the available solutions do not provide for the possibility of assessing the sufficiency of information for decision-making in the "Smart House" cyber-physical system.Therefore, there is a need to develop such methods and tools for situation identification and decision-making support in the "Smart House" cyber-physical system, which would: perform situation recognition for all 5 groups of the system of managed housing functions; provide the decision-making support for all 5 groups of the system of managed housing functions; perform an assessment of the sufficiency of information for making all decisions in the "Smart House" cyber-physical system, which will be the focus of the authors' further efforts.

    Rules and method of supporting the decision-making regarding the possibility of extracorporeal fertilization
    (Хмельницький національний університет, 2022) Hnatchuk, Ye.; Hovorushchenko, T.
    Considering the impossibility of applying for the paid services of a lawyer in most medical clinics, the legal correctness of decisions regarding the provision of various medical services can be significantly increased by a decision support system or technology regarding the possibility of providing medical services –atthe expense of providing a conclusion on the possibility or impossibility of providing this or that medical service, taking into account civil legal grounds.The conducted analysis proved that none of the known systems/technologies are intended to support decision-making regarding the possibility of providing the extracorporeal fertilization, taking into account civil legal grounds. Although the use of such cross-disciplinary systems/technologies can significantly increase the correctness of the decision from a legal point of view, protect the doctor and the patient from legal collisions, provide an opportunity for a quick and free check of the presence of all significant conditions from a legal point of view, as well as recommendations for further implementation or non-implementation of extracorporeal fertilization procedures.The article develops rules and method of supporting the decision-making regarding the possibility of extracorporeal fertilization based on the civil legalgrounds, which reflect the peculiarities of decision-making on whether or not to carry out extracorporeal fertilization based on the assessment of the sufficiency of information (compliance with requirements) for such a procedure, ensure adaptation to the specifics of the subject area and is a theoretical basis for the development of a decision-making support system/technology regarding the possibility of providing the extracorporeal fertilization, taking into account civil legal grounds.The developed rules and method ensure: verification of the agreementfor the provision of extracorporeal fertilization services for the fulfillment of all essential conditions for the provision of in vitro fertilization from the point of view of civil legal grounds without the participation of legal experts, which ensures the possibility for medical clinics to comply with the requirements of current civil legislation without paying for the services of hired lawyers; a conclusion on the possibility or impossibility of providing the extracorporeal fertilization from the point of view of the civil legislation of Ukraine.The direction of the authors' future research is the realization of the subsystem of information technology for medical decision-making support taking into account civil legal grounds in the form of web-oriented software based on the developed method of supporting the decision-making regarding the possibility of extracorporeal fertilization taking into account civil legal grounds.
