ВИЯВЛЕННЯ ЛІДЕРСЬКИХ ЯКОСТЕЙ СЕРЕД СТАРШИХ МЕДИЧНИХ СЕСТЕР

Summary. The urgent need to reform Ukraine’s health care system requires a qualitatively new approach to governance at both the state and health care levels. The aim of the study – to analyze the contingent of senior nurses in terms of assessment of leadership qualities and training in the organization and management of the health care system. Materials and Methods. The study involved 25 senior nurses of the municipal institution “Dnipropetrovsk Specialized Clinical Medical Center of Mother and Child named after Prof. M. F. Rudnev” Dnipropetrovsk Regional Council”, who answered the questions of our questionnaire. Results. With the maximum possible amount of points equal to 250, the total average score was (180.32±4.06), which indicates the need for more thorough training of real and potential managers in various aspects of management. Their positions are quite strong in relations with senior management, in matters of strategic management, in general a positive assessment of innovation, in-depth knowledge of professional issues, as well as in the fact that they highly value the teams in which they work. At the same time, they do not always have clear enough criteria for assessing the qualities of specific employees; they clearly do not fully trust and do not always consult with the team, on the one hand, and, on the other hand, do not clearly control its work. Conclusions. The development of leadership skills of senior nurses is the key to improving the efficiency of nursing staff management.Резюме. Нагальна необхідність реформування системи охорони здоров’я України потребує якісно нового підходу до управління як на державному рівні, так і на рівні закладу охорони здоров’я. Мета дослідження – проаналізувати контингент старших медичних сестер з точки зору оцінки лідерських якостей та підготовленості в питаннях організації та управління в системі охорони здоров’я. Матеріали і методи. У дослідженні взяли участь 25 старших медичних сестер комунального закладу «Дніпропетровський спеціалізований клінічний медичний центр матері та дитини імені проф. М. Ф. Руднєва» Дніпропетровської обласної ради», які відповіли на запитання розробленого нами опитувальника. Результати. При максимально можливій сумі балів, що дорівнює 250, сумарний середній бал був 180,32±4,06, що свідчить про необхідність більш ґрунтовної підготовки реальних і потенційних керівників із різних аспектів менеджменту. Їх позиції є досить сильними у відносинах із вищим керівництвом у питаннях стратегічного управління, в цілому позитивній оцінці інновацій, у глибоких знаннях професійних питань, а також в тому, що вони високо цінують колективи, в яких працюють. У той же час не завжди у них є досить чіткі критерії для оцінки якостей конкретних співробітників; вони явно не повністю довіряють і не завжди радяться з колективом, з одного боку, і, з іншого, недостатньо чітко контролюють його роботу. Висновки. Розвиток лідерських якостей старших медичних сестер є запорукою підвищення ефективності управління сестринським персоналом

Computer simulation radiation damages in condensed matters

As part of the cascade-probability method were calculated the energy spectra of primary knocked-out atoms and the concentration of radiation-induced defects in a number of metals irradiated by electrons. As follows from the formulas, the number of Frenkel pairs at a given depth depends on three variables having certain physical meaning: firstly, C[d] (E[a] h) is proportional to the average energy of the considered depth of the PKA (if it is higher, than the greater number of atoms it will displace); secondly is inversely proportional to the path length [lambda]2 for the formation of the PKA (if [lambda][1] is higher than is the smaller the probability of interaction) and thirdly is inversely proportional to E[d]. In this case calculations are in satisfactory agreement with the experimental data (for example, copper and aluminum)

Coupled system of electrons and exciton-polaritons: Screening, dynamical effects, and superconductivity

Bose-Fermi systems such as mixtures of electrons with excitons or exciton-polaritons are extensively discussed as candidates to host a variety of intriguing phenomena, including polaron formation, drag effects, supersolidity, and superconductivity. In this work, assuming the strong-coupling regime between the semiconductor excitons and cavity photons, we develop the many-body theory approach addressing the interplay of different types of interaction among various species in such a mixture, wherein we take into account dynamical density responses of both the Bose-condensed exciton-polaritons and the two-dimensional electron gas inside an optical microcavity. As was anticipated previously, at high enough polariton densities the lower hybrid mode of the system's excitation spectrum acquires a roton minimum, making the system prone to superconducting pairing in the vicinity of the roton instability. We analyze the possibility of polariton-BEC-mediated superconductivity in the electron gas taking into account full momentum and frequency dependence of the gap, as well as in the Eliashberg approach where the momentum dependence is neglected, and in the Bardeen-Cooper-Schrieffer approach that discards the frequency dependence and dynamical effects. Considering the interaction screening in Thomas-Fermi and in random-phase approximations, we estimate the critical temperatures of superconductivity to be not larger than 0.1 K in the vicinity of instability. As possible realizations of the coupled polariton-electron system, semiconductor quantum wells and two-dimensional transition metal dichalcogenides are considered.Comment: 19 pages, 8 figure

Isolation of Soil Thiobacterii and Determination of Their Bio-Oxidation Activity

36 strains of sulfur-oxidizing bacteria were isolated in Southern Kazakhstan soda-saline soils and identified. Screening of strains according bio-oxidation (destruction thiosulfate to sulfate) and enzymatic (Thiosulfate dehydrogenises and thiosulfate reductase) activity was conducted. There were selected modes of aeration and culture conditions (pH, temperature), which provide optimum harvest cells. These strains can be used in bio-melioration technology
