    The article attempts to investigate the relationship of coping strategies and protective mechanisms of the personality of student teachers with different levels of neurotization. It is noted that the presence of effective coping strategies and protective mechanisms of the personality is a condition for successful professional activity of future teachers, as well as somatic and psychological health. The article presents the theoretical and methodological basis of the study, the lack of sophistication and fuzziness of the concepts of psychological defense, neurotization and the state of neurotization, the methods of collecting empirical data are presented. An analysis of the data allowed us to see that more than half of the student teachers have psychosomatic or somatoform diseases against the background of an increased level of mental stress and neurotization. The research made it possible to identify a stable system of psychological defenses and non-adaptive coping strategies among psychology students with a high level of neurotization and substantiate the recommendation for the targeted formation of more mature and adequate adaptation strategies in student teachers of this group.Π’ ΡΡ‚Π°Ρ‚ΡŒΠ΅ прСдпринята ΠΏΠΎΠΏΡ‹Ρ‚ΠΊΠ° ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Ρ‚ΡŒ взаимосвязь ΠΊΠΎΠΏΠΈΠ½Π³-стратСгий ΠΈ Π·Π°Ρ‰ΠΈΡ‚Π½Ρ‹Ρ… ΠΌΠ΅Ρ…Π°Π½ΠΈΠ·ΠΌΠΎΠ² личности студСнтов-ΠΏΠ΅Π΄Π°Π³ΠΎΠ³ΠΎΠ² с Ρ€Π°Π·Π½Ρ‹ΠΌ ΡƒΡ€ΠΎΠ²Π½Π΅ΠΌ Π½Π΅Π²Ρ€ΠΎΡ‚ΠΈΠ·Π°Ρ†ΠΈΠΈ.

    Respiratory diseases persistently lead in the structure of general morbidity in both children and adolescents. Acute respiratory infections are the most common among them. Interest of pediatricians to phytotherapy is not accidental and is due to the fact that it has a mild therapeutic effect, enhances the effectiveness of complex therapy, has few side effects. Of particular interest are herbal remedies containing ivy extract (Hedera helix), the active ingredients are mainly found in ivy leaves, they are biologically active substances: Triterpene saponins, glycosides, also contain carbohydrates, essential oils, steroids, phenolcarboxylic acids, coumarins, flavonoids, carotenoids, tocopherols (vitamin E), B and C vitamins, tannins, phytoncides. Ivy preparations are prescribed as an expectorant in the treatment of infectious and inflammatory diseases of the upper and lower respiratory tract due to their proven multidirectional effects: secretolytic, mucolytic, bronchospasmolytic. They also have anti-inflammatory, reparative, antioxidant effects.This article presents a clinical example of an officinal ivy-based preparation used in the treatment of a 3.5 year old patient diagnosed with acute respiratory viral infection. Temperature increased to 38 Β°C, runny nose; on the second day of illness the temperature remained subfebrile and a dry cough appeared. Nasal vasoconstrictor drops and oral acetylcysteine were prescribed, but there was no relief. On the third day of the illness, against the background of subfebrile temperature, the cough persisted, single dry rales were heard in the lungs, wheezing appeared during physical exertion. Acetylcysteine was withdrawn and replaced by ivy-based drops (16 drops 3 times a day orally after meals in a small amount of water). After 2 days the cough was moist, the sputum was easily expectorated, the wheezing in the lungs was almost gone, there was no more wheezing and the temperature was normal. By the sixth day of treatment the cough was gone and the girl had almost recovered. Nevertheless, Gedelix was continued for another 4 days. Prospective results and detailed study of the effects of herbal preparations on the basis of ivy extracts served as the basis for their recommendation as a complex therapy of cough in children

    Within the framework of an interdisciplinary approach at the intersection of economics and social psychology, an attempt was made to identify the influence of the interaction of economic and socio-psychological factors on the result of a Joint-Stock Company’s activities and readiness for innovation in conditions of unpredictability. The indirectness of ownership affects the accuracy and adequacy of assessing the situation, oneself, and others, predetermines the employees’ sense of stability, underestimation of the role of the consumer, the personal influence of employees on the effectiveness of the organization’s activities and does not contribute to the transition to a marketing organizational culture.Π’ Ρ€Π°ΠΌΠΊΠ°Ρ… мСТдисциплинарного ΠΏΠΎΠ΄Ρ…ΠΎΠ΄Π° Π½Π° стыкС экономики ΠΈ ΡΠΎΡ†ΠΈΠ°Π»ΡŒΠ½ΠΎΠΉ психологии Π±Ρ‹Π»Π° прСдпринята ΠΏΠΎΠΏΡ‹Ρ‚ΠΊΠ° выявлСния влияния взаимодСйствия экономичСских ΠΈ ΡΠΎΡ†ΠΈΠ°Π»ΡŒΠ½ΠΎ-психологичСских Ρ„Π°ΠΊΡ‚ΠΎΡ€ΠΎΠ² Π½Π° Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚ Π΄Π΅ΡΡ‚Π΅Π»ΡŒΠ½ΠΎΡΡ‚ΠΈ Π°ΠΊΡ†ΠΈΠΎΠ½Π΅Ρ€Π½ΠΎΠ³ΠΎ общСства ΠΈ готовности ΠΊ инновациям Π² условиях нСпрСдсказуСмости.

At the same time, the university teachers have a question: what are the skills of real goal-setting and self-organization, as well as the skills of planning and self-control among freshmen students? How can these skills and abilities be activated in the scientific process? The aim of the work is to study the features of self-organization among freshmen students

    Comparative evaluation of the effectiveness of cervical cerclage and use of cervical pessary for correction of isthmico-cervical incompetence during pregnancy

    Get PDF
    For correction of isthmico-cervical incompetence of 141 patients the cervical obstetric pessary was used, cervical cerclage was used, for 71 pregnant woen in control group. The level of preterm birth at <33 weeks in the group, corrected cervical pessary, was 9.9%, which was significantly lower than the 24.5% corrected with cerclage. Cervical pessary has an advantage when it is used in gestation over 20 weeks, when the performance of cerclage is associated with a high risk of or after an unsuccessful attempt of cerclage, has a higher safety profile. The usage of cervical pessary should be considered the first-line therapy among patients with a short cervix according to ultrasound data and the absence of preterm birth history.Для ΠΊΠΎΡ€Ρ€Π΅ΠΊΡ†ΠΈΠΈ ИЦН Ρƒ 141 ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚ΠΊΠΈ основной Π³Ρ€ΡƒΠΏΠΏΡ‹ примСнялся Π°ΠΊΡƒΡˆΠ΅Ρ€ΡΠΊΠΈΠΉ пСссарий, Ρƒ 71 Π±Π΅Ρ€Π΅ΠΌΠ΅Π½Π½ΠΎΠΉ ΠΊΠΎΠ½Ρ‚Ρ€ΠΎΠ»ΡŒΠ½ΠΎΠΉ Π³Ρ€ΡƒΠΏΠΏΡ‹ - сСркляТ шСйки ΠΌΠ°Ρ‚ΠΊΠΈ.

    Optimizing a low-temperature preservation technique for Bacillus anthracis strains

    Get PDF
    The use of pure microbial cultures is associated with the following key challenges: storage, transportation and resuscitation after a long-term preservation. The currently used anthrax vaccines are produced using various strains of Bacillus anthracis. According to the storage passport data, anthrax strains are now stored in 30–40% glycerin solutions, which helps to preserve a sufficient number of viable cells without losses to their pathogenic properties for three years. It is obviously an urgent task to develop a long-term preservation technique for Bacillus anthracis strains. The aim of this study was to optimize a low-temperature preservation method for Bacillus anthracis strains that ensures viability and no losses to biological properties of the pathogen. Two vaccine strains of Bacillus anthracis were selected for the research: i.e. K-STI-79 and 55-VNIIVViM and two cryoprotective media (No. 1 – 15% glycerin solution with 15% glucose solution and No. 2 – 30% neutral glycerin solution in saline solution). At first biological properties of the strains were studied and the number of viable cells was calculated. Later on, the strains were placed into low-temperature preservation facilities, at the temperature of –40 and –70 Β°C. Six months later, the effect of three thawing cycles on viability and biological properties of the agent was tested: i.e. at room temperature (22 Β± 2) Β°C, in a water bath at a temperature of (37 Β± 1) Β°C and in a household refrigerator at a temperature of (6 Β± 2) Β°C. As demonstrated, the best option is to preserve the cells at –70 Β°C and thaw them in a water bath at (37 Β± 1) Β°C. Further research will be focused on duration of the low-temperature preservation that will ensure appropriate viability and biological properties of the pathogen

    The peculiarities of German and French toponymic systems are the result of historical and extralinguistic development. The system of word forming patterns and its structural components are represented as a result of the interaction of languages. It allows to analyse German and French toponyms as subsystems of onymiс vocabulary. Loan formants, which determined social-cultural nature of toponyms, are considered. Special attention is paid to the process of onymization of appellatives. Structural modeling of German and French toponyms is presente
