An infrastructure factor in regional competitiveness

This research deals with the role of infrastructure in the development of sustainable and competitive development of the territorial, socio-economic system of the region. Individual components of the regional infrastructure and their contribution to the territories' development are defined. Economic and geographic analysis of the competiveness of the six economic regions in the Republic of Tatarstan is conducted. The analysis is based on comparison of various indicators, which characterize distribution and quality of infrastructure facilities. Spatial habitats with high competitive development potential are defined by further increasing of an agricultural specialization and establishing of vertically and horizontally integrated production structures. They are industrial, economic regions which concentrate the main part of popularity and funds and identify perspective opportunities of economic restructuring. The second group of areas have at most agrarian and industrial specialization, and more often just agrarian as inert sphere of socio- economic space of the region

Influence of psychosocial risk factors on the dynamics of indicators of temporomandibular disorders

Aim. To analyze the influence of psychosocial risk factors on the dynamics of indicators characterizing temporomandibular disorders. Methods. 61 clinical cases of temporomandibular disorders with chronic pain were investigated (18 % of the total number of observations of temporomandibular disorders). Diagnostic criteria of temporomandibular disorders were used: axis II, computed tomography and magnetic resonance imaging of temporomandibular joint. Interviewing method was used for clinical diagnosis of psychological phenomena and testing attitude to the disease, identifying communicative deviations according to R.C. Rogers (2002). Patients were divided into 2 groups: group A - patients with nociceptive pain, social adaptation is not disturbed; group B - patients with neuropathic pain, psychosomatization on the background of mental rigidity. In both groups, an identical treatment regimen was implemented for two years. Statistical processing of the obtained data was carried out using IBM SPSS 21 and included comparison of related groups by Friedman analysis and paired Wilcoxon test, comparison of independent groups by Mann-Whitney-Wilcoxon criterion, and comparison of the qualitative features by contingency tables by Chi-square Pearson. Results. The radiological semiotics of temporomandibular joint in both groups is similar in the structure of nosology. At the beginning of the treatment cycle, the pain intensity and the temporomandibular index are similar. After 2 years of follow-up, patients in group A showed a significantly higher positive response to the therapy compared to patients in group B: pain intensity in group A was 15.36±2.53 and in group B - 37.32±3.45 (p<0.001); depression on the SCL-90-R scale - 0.29±0.04 and 1.12±0.12 (p<0.001), the degree of disability on the GCPS scale - 0.68±0.08 and 1.17±0.10 (p=0.001), temporomandibular index - 0.15±0.01 and 0.23±0.02 (p<0.001), respectively. Conclusion. In patients of group B, affective disorders form the psychosomatic structure of personality and affect the outcome of therapy. When formulating the final diagnosis and planning the treatment in patients with temporomandibular disorders, it is necessary to take into account the psychosocial characteristics of the patient

Research of academic motivation at the stage of forming a threshold level of mastering competences

РІВЕНЬ ГОРМОНІВ СТРЕС-ЛІМІТУЮЧОЇ СИСТЕМИ У ВАГІТНИХ З ПСИХОЕМОЦІЙНИМИ ПОРУШЕННЯМИ, ОБУМОВЛЕНИМИ ТРИВОЖНІСТЮ

Мета дослідження – визначити рівень гормонів стрес-лімітуючої системи у вагітних з урахуванням їх психоемоційного стану. Матеріали та методи. Обстежено 86 жінок у ІІ та на початку ІІІ триместру вагітності. До основної групи включені 60 вагітних із середнім та високим рівнями ситуативної тривожності, а також 26 вагітних із рівнем тривоги 30 балів і нижче, що свідчить про низький рівень СТ (група порівняння). Для оцінки ситуативної тривожності та особистісної тривожності використовували шкалу Ч. Д. Спілбергера, яка адаптована Ю. Л. Ханіним. Кількісну оцінку концентрації гормонів у плазмі крові визначали методом імуноферментного аналізу на апараті «SIRIO S». Для визначення рівня пролактину (Пр) використовували тест-систему Monobind INC (США), кортизолу (К) та інсуліну (Ін) – тест-системи DRG (Німеччина). Рівень ендогенних опіоїдних пептидів (β-ендорфіну) визначали з використанням тест-системи Peninsula Laboratories, LLC (США). Результати дослідження та їх обговорення. Групи дослідження були розділені залежно від рівня СТ. Встановлено, що середній показник СТ у групі порівняння склав (26,3±1,2) бала та був статистично достовірно нижчим (p0,05). Однак розрахунок К/Ін індексу, як маркера стресу, дозволив встановити його статистично достовірне (p0,05) між показниками у вагітних із середньо-високим – 1,2 (0,6; 3,6) нг/мл та низьким – 1,4 (0,7; 3,0) нг/мл рівнями СТ. Вірогідно, це свідчить про відсутність виразного впливу означеного нейропептиду на формування емоційного стану в жінок під час вагітності. Висновки. Оцінка рівня пролактину, як ендогенного анксіолітика, дозволила встановити статистично достовірне (р0,05) та позитивний – із рівнем СТ (r = +0,576, p0,05). Однак визначення К/Ін індексу, як маркера стресу, дозволило встановити його статистично достовірне (p<0,05) переважання в групі вагітних із середньо-високим рівнем, порівнюючи з вагітними, які мали низький рівень СТ
