The work is devoted to the problem of developing the structure of an organic light-emitting diode (OLED) and mixed signal front-end with extended functionality, specifically, in-situ measurement of the current-voltage (I-V) characteristics of the structure directly during their operation. The OLED structure uses long-term thermally activated delayed fluorescence (TADF) of the TPAPm organic film. The measurement of I-V characteristics of OLED structures is carried out on the transient processes of voltage formation in the step-up circuits of the drivers. The OLED front-end is implemented on a programmable system on a PSoC chip of the 5LP Family Cypress Semiconductor Corporation. The results of the work are used for optical MEMS sensors using organic light sources.

Abstract: A full-scale russian-Ukrainian war has been going on for about nine months. Almost every day, Ukrainian cities suffer from enemy raids of missiles and drones, as a result, civilians become victims of hostilities. The prevalence of mine blast injury in these conditions is extremely high. Unfortunately, this type of injury is often accompanied by massive bleeding,which forces to make amendments in a treatment strategy. According to world standards, the first infusion solution for this category of patients should be whole blood, because of its numerous advantages. At the Multidisciplinary Clinical Hospital of Emergency and Intensive Care in Lviv, this strategy has been used almost since the first days of the war for patients of all age groups. In the article, we present a convincing evidence base of the advantages of using whole blood, as well as a clinical case of using whole blood infusion in a pediatric patient.
Резюме: Близько дев’яти місяців на теренах України точиться повномасштабна російсько-українська війна. Майже щодня українські міста потерпають від ворожих нальотів ракет та дронів, внаслідок чого стають жертвами мирні жителі. Мінно-вибухова травма – діагноз, з яким доводиться відтепер працювати постійно. На жаль, даний вид травми часто супроводжується масивною кровотечею, що змушує змінювати тактику надання медичної допомоги. Відповідно до світових стандартів першим інфузійним розчином для даної категорії пацієнтів повинна бути цільна кров, адже вже неодноразово були доведені її численні переваги. У КНП «Перше територіальне медичне об’єднання м. Львова» дана тактика застосовується ледь не з перших днів війни для пацієнтів усіх вікових груп. У статті наводимо переконливу доказову базу переваг використання цільної крові, а також особистий досвід на основі опису клінічного випадку пацієнта з педіатричної групи
The rapid development of modern scientific medicine and practice (development of genetic engineering, coronary angiography, use of microprocessors (microminiature implant in eye retina, 3D-print of implants, prostheses) is connected with the scientific-technical progress in recent years, which gave impetus to introduction of extremely complex treatment and diagnostic methods. The use of high-tech medical equipment requires the implementation of modern sanitary and antiepidemic measures of disinfection and sterilization after each manipulation to prevent in-hospital infection/infectious diseases which are related to the grant of medicare (IHI/IPNMD). Every year in the USA, up to 2 million patients who received medical services are registered with IHI/IPNMD cases. IHI/IPNMD is the cause of increased mortality, disability, lengthens stay period of patients in hospitals, increases the financial burden on both patients and healthcare system. According to WHO data mortality from IHI/IPNMD among adult patients ranges from 18.5% to 29.6% and in countries with low- and middle-income level fluctuate in the range of 8.8%-88.9%. Thus, the vital issue today is to strengthen the control system over IHI/IPNMD at all stages of its spread, namely: early detection of sick persons and carriers among patients and medical personnel, monitoring resistance to antibiotics and control over their use in patients treatment, expanding the range of scientific research in the development of new groups of antibacterial drugs, compliance with the sanitary-epidemic regime in hospitals, including the elaboration of modern disinfectants and sterilization agents.
This article discusses the characteristics of the design of thermoelectric generators (TEGs) for cold climates. Since the thermocouples of thermoelectric batteries are produced from different materials, their major properties are studied. Particular attention is given to nanostructured materials regarding the modern class of thermoelectric materials. Two-, three-, and four-component alloys (metallic glasses) of the Fe-Ni(Cu)-P-B system are chosen based on the experience of thermoelectric thermometry. The close chemical composition of two thermoelectrodes enables their compatibility in thermocouple production and satisfactory thermoelectric efficiency of batteries during long-term operation. The improvement of the thermoelectric battery characteristics related to a unit of mass is evaluated. The materials studied are distinguished by the absence of toxic components harmful to the environment at the manufacturing and operating stages.
Pain is an interdisciplinary problem at the border of medicine, psychology, sociology and economics. Pain syndrome reduces the quality of life of patients, affects work productivity, social adaptation, and in most cases is poorly amenable to treatment. Therefore, a multidisciplinary approach to the diagnosis and treatment of pain syndrome is important, which should take into account the peculiarities of the patient’s perception of pain, the patient’s psycho-emotional state, individual life experience and previous experience of feeling pain, which will make it possible to improve the effectiveness of treatment, reduce the number of used painkillers and, accordingly, improve patient’s quality of life. Based on the analysis of modern literary sources, the article presents an expanded concept of pain, pathogenetic and biochemical mechanisms of its occurrence, approaches to treatment.
