The possibility of sucralose and lugduname electrochemical determination in beverages has been analyzed for the first time from a theoretical point of view. It has been shown that the electrochemical determination of sucralose and lugduname may be carried out efficiently by an anodic process due to the presence of electroactive groups in both substances despite the hybrid mechanism for lugdunam electrooxidation. The stability analysis of the system from the steady-state formation and maintenance point of view confirms that the neutral or mildly acidic medium is favorable for the determination of both sweeteners
In the work, a study of the design and technological direction of creating a dual-functional non-contact pressure and temperature sensor based on silicon-cholesteric crystal systems was carried out. An optically active environment based on a supramolecular spiral structure is a sensitive element for forming the optical response of a microelectronic label sensor during non-contact monitoring of the state of a physical object using a spectrometer. The optical response of the device provides maximum intensity in the case of interference that corresponds to the Wulff–Bragg condition. The functionality of the sensor is ensured by the conditions for avoiding high electromagnetic interference during optical identification. A hardware and software modules have been created for non-contact monitoring of the state of physical objects, the main part of which is graphical user interface that corresponds to the MVVM architectural design pattern. Visualization of the spectral intensity using the software module was provided by conversion to the RGB model. The algorithm of procedure for calculating the color rendering index is given. In a wide range of light waves, the main parameters' color temperature was defined.
Application of intelligent expert systems for structuring and automation of laboratory activities in the educational process has been analysed. It is shown that combination of teaching materials with cross-references and transitions by the means of expert systems allows educators to make optimal decisions on time, set priorities and prepare more effective laboratory classes. The implementation of expert systems for classification sections of academic disciplines in both engineering and technical sciences and humanities has been discussed. An algorithm for making decisions by an expert system, where the main emphasis is given to laboratory tasks and work with laboratory equipment, is proposed. It is shown how to develop a new expert system which can help university educators prepare remote laboratory work, and also to use of virtual simulators or effective practical training. The proposed expert systems can be used for classifying thematic sections of a wide range of disciplines, including natural sciences, engineering, and humanities. They can be used for preparing new courses and training new educators in different areas. Thus expert systems are described as high-scale software units without restrictions on the depth of the question tree and the number of logical branches of the classifier.
Prolonged exposure to elevated temperatures exceeding 47°C,which can occur during root canal obturation,can cause damage ofboth dental and bonetissues. In orderto study the temperature distribution on the surfaceof the tooth rootatemperature measuring device with cold-junction compensation is proposed. For in vitro measurement of the temperature distribution on the surface of the tooth, 8 thermocouples placed in direct contact with the cementum of the tooth were used.In order to eliminate thecold-junction temperature variations,the temperature equilibration device and RTD wereused. The suggested linear approximation for the thermocouples'conversionfunction providesa nonlinearity relativeerror of less than 0.05%for K-type thermocouples and 0.07% for J-type thermocouples over the temperature range from20 to 60°C.

Метою статті є аналіз ролі інформаційних технологій в освітньому процесі майбутніх медичних фахівців. З’ясовано, що інтенсивний розвиток інформаційно-комунікаційних технологій сприяв появі, удосконаленню та оновленню сервісів медичного обслуговування. Основними тенденціями в галузі охорони здоров’я України за останні роки стали цифровізація, телемедицина, впровадження електронних медичних записів (ЕМЗ), застосування аналітики. Впровадження інформаційних систем у медичну сферу України значно спростили організаційні аспекти роботи відповідних закладів, включаючи системи запису на прийом, електронний реєстр пацієнтів та оброблення облікової і статистичної інформації. Ці тенденції зумовили пошук найефективніших інструментів та підходів до підготовки майбутніх медичних працівників. Сучасні виклики, а також запровадження воєнного стану на території країни зумовили необхідність застосування дистанційної та змішаної форм навчання. У медичних закладах вищої освіти України активно використовуються такі цифрові ресурси, як системи управління навчанням, платформи для створення документів та мультимедійних презентацій, інтерактивні дошки, платформи відеозв’язку тощо. Нові можливості для викладання та навчання в освіті у сфері охорони здоров’я відкривають технології на основі доповненої і віртуальної реальності та штучний інтелект. Використання таких технологій сприяє підвищенню рівня засвоєння матеріалу здобувачами освіти та розвитку в них необхідних професійних навичок. Загалом, інформаційні технології мають значний вплив на освіту у сфері охорони здоров’я в Україні, трансформуючи підходи до передачі знань і розширюючи можливості доступу до різноманітних ресурсів. Стрімкий розвиток цифрових технологій потребує від працівників медичної галузі високого рівня цифрової компете нтності, тому впровадження інформаційних технологій в освіту у сфері охорони здоров’я сприятиме формуванню фахівців, які ефективно використовуватимуть різні інновації у своїй професійній діяльності, що сприятиме вдосконаленню медичної галузі.
The purpose of the article was to analyze the role of information technologies in the educational process of future medical specialists. An analysis of
the latest scientific works was conducted, in which the trends in medicine and medical education were considered, and relevant conclusions were drawn thanks to the method of generalization. It was found that the intensive development of information and communication technologies contributed to the emergence, improvement and renew al of medical services. Digitalization, telemedicine, the introduction of electronic medical records (EMR), and the use of analytics in health care have become the main trends in the field of healthcare in Ukraine in recent years. The implementation of information systems in the medical field of Ukraine significantly simplified the organizational aspects of the work of the relevant іnstitutions, including appointment systems, electronic patient registers and processing of accounting and statistical information. These trends led to the search for the most effective tools and pproaches to the training of future medical professionals. Modern challenges, as well as the implementation of martial law in the country, necessitated the use of distance and mixed forms of education. Digital resources such as learning management systems, platforms for creating documents and multimedia presentations, interactive whiteboards, video communication platforms, etc. are actively used in medical institutions of higher education in Ukraine. Technologies based on augmented reality and virtual reality, as well as artificial intelligence, open up new opportunities for teaching and learning in
medical education. The use of such technologies helps to increase the level of assimilation of the material by the students of education and the development of their necessary professional skills. In general, information technologies have a significant impact on medical education in Ukraine, transforming approaches to knowledge transfer and expanding access to various resources. The rapid development of digital
technologies requires a high level of digital competence from specialists in the medical field. The implementation of information technologies in medical education will contribute to the formation of specialists who will effectively use various innovations in their professional activities, which will contribute to the improvement of the health care industry.
