ОРГАНІЗАЦІЯ НАВЧАЛЬНОГО КУРСУ “ТРАВМАТОЛОГІЯ ТА ОРТОПЕДІЯ” ДЛЯ ІНОЗЕМНИХ СТУДЕНТІВ У БУКОВИНСЬКОМУ ДЕРЖАВНОМУ МЕДИЧНОМУ УНІВЕРСИТЕТІ

The aim of the work – to analyze tutorial process and to improve the quality of education for English speaking students at “Traumatology and Orthopedics” course.The main body. Paper presents analysis of tutorial process on “Taumatology and Orthopedics” students of foreign faculty of Bukovynian State Medical University. Peculiarities of theoretical and practical study were described. It was estimated that main problems are lack of tutorial hours that were given for learning the discipline, the quantity and quality of English textbooks and methodical instructions are very low. Problems with patient’s curation are related with low level of Ukrainian language and big number of students in groups, that complicates individual approach to mastering practical skills. To resolve the abovementioned problems the distant educational course of “Traumatology and Orthopedics” was introduced. Decreasing number of students in the groups and involvement them to participate in urgent duties will improve the level of theoretical and practical knowledge, motivation and enquiring of students in Traumatology and Orthopedics and will make educational process more individually oriented. Another perspective goal is to compile and publish quality English textbooks and handbooks on “Traumatology and Orthopedics”.Conclusions. Significant improvement of theoretical knowledge and developing the “orthopedics focus” can be achieved with application of modern distant internet-based learning technologies that helps students to improve practical skills as well. On the other hand solving number of problems, as preparing and publishing quality textbooks and methodical instructions on “Traumatology and Orthopedics” course in English, improving website of distant learning, decreasing number of students in groups will improve the quality of learning the discipline.Мета роботи – провести аналіз навчального процесу англомовних студентів та покращити якість вивчення травматології та ортопедії.Основна частина. Проведено аналіз навчального процесу з дисципліни “травматологія та ортопедія” студентів іноземного факультету Буковинського державного медичного університету, наведено особливості їх теоретичної і практичної підготовки. Визначено, що основними перешкодами є недостатня кількість навчальних годин, що відводяться для дисципліни, брак навчальної літератури англійською мовою та її якість, труднощі при курації хворих пов’язані з недостатнім знанням української мови іноземцями, велика кількість студентів у групах, що утруднює індивідуальний підхід при проведенні практичних занять. Створення сервера дистанційного навчання й електронного навчального курсу “травматологія та ортопедія” покращило навчальний процес. Зменшення кількості англомовних студентів у групах та залучення їх до ургентних чергувань дозволять значно покращити рівень теоретичної і практичної підготовки, посилити мотивацію і зацікавленість студентів, сприятимуть індивідуальному підходу до їх навчання. Перспективними є також підготовка і видавництво власної навчально-методичної літератури англійською мовою.Висновки. Значного покращення теоретичних знань студентів та розвитку їх ортопедичної спрямованості можна досягти, застосовуючи сучасні технології дистанційного навчання з застосуванням Інтернету, що, у свою чергу, покращить оволодіння студентами практичними навичками. З іншого боку, вирішення ряду проблем, таких, як видавництво якісних підручників та навчально-методичних посібників з травматології та ортопедії англійською мовою, удосконалення веб-сайту дистанційної освіти, зменшення кількості студентів у групах, також значно покращить якість вивчення дисципліни

PREDISPOSING FACTORS AND TREATMENT OF OSTEOARTHRITIS AFTER SURGERIES PERFORMED FOR TIBIAL FRACTURES

Tibial fractures are very common injuries that require surgical management. For many cases, when the fracture involves the joint further complications occur, such as joint stiffness, osteoarthritis, aseptic necrosis of articular surfaces, ankylosis, infection complications, etc. To prevent joint stiffness open reduction and internal fracture fixation is used. That allows better positioning of fracture fragments forming joint surface and improve outcome. The article analyses results of surgical treatment of intraarticular fractures as well as biomechanical factors that are affecting the joint within the healing process and in later outcome period. Various treatment procedures are suggested to prevent development of osteoarthritis or to decrease its severity. The following options are used on all stages of treatment starting since the moment of injury, primary surgical procedures, rehabilitation period, and further non-surgical treatment in the internal medicine department. Important roles are assigned for use of chondroprotective drugs, intraarticular injections of Hyaluronic acid, physiotherapy and physical activity.Tibial fractures are very common injuries that require surgical management.

Parrondo-like behavior in continuous-time random walks with memory

The Continuous-Time Random Walk (CTRW) formalism can be adapted to encompass stochastic processes with memory. In this article we will show how the random combination of two different unbiased CTRWs can give raise to a process with clear drift, if one of them is a CTRW with memory. If one identifies the other one as noise, the effect can be thought as a kind of stochastic resonance. The ultimate origin of this phenomenon is the same of the Parrondo's paradox in game theoryComment: 8 pages, 3 figures, revtex; enlarged and revised versio

Performing total knee replacement in cases with various degrees of bone loss

The paper analyses main factors that effect treatment results of total knee arthroplasties in cases of bone defects, such as a size and types of bone defects, their connection with previous surgeries, existing classification with their benefits and weak points. Authors show various possibilities of surgical treatment of bone defects that can provide better stability for prosthetic devices. The importance of bone grafts is highlighted as their remodeling provides the base for implant stability in late period of outcome

Spin 2 Particle with Anomalous Magnetic Moment in Riemann Space-Time: A Massless Case with the Gauge Symmetry

The most of studies in the theory of spin 2 _field were performed with the use of the 2-nd order equations. The spin 2 particle theory proposed by F.I. Fedorov is based on the first order equations requires a 30-component set of tensors. Besides, by him and coauthors was elaborated a more general theory, which is based on 50-component set of tensors. In the present paper, we consider this more general theory in presence of arbitrary electromagnetic fields and Riemannian space-time backgrounds. First we study the 50-component theory for a massive particle. In this case, there arises the non-minimal interaction with the curved space-time background through the Ricci and Riemann tensors. It is important that the theory under consideration allows for a new massless limit for the spin 2 field. This fact is of special interest, because the conventional Pauli - Fierz theory for the massless field does not possess gauge symmetry in the curved space-time, in particular, in models with the vanishing Ricci tensor. We show that the generalized theory possesses such a gauge symmetry in all space-time models for which the Ricci tensor vanishes

Development of overtraining syndrome: survey of hypotheses

This review presents current summarized knowledge on definition, causes, symptoms and evidence of overtraining syndrome in athletes. Analysis of biochemical, physiological, endocrine, neuronal and mycological parameters, each of which is potentially involved in understanding of the metabolic aspects of overtraining syndrome, is required to study the latter. The development of overtraining syndrome is explained by numerous hypotheses with their own strengths and weaknesses. Each theory is centered around a key parameter, disbalance of which can lead to overtraining during the execution of long-term high intensity training loads. Obviously none of isolated markers can be used for diagnostic purposes. A comprehensive approach to explain overtraining syndrome development is provided by a theory of cytokines

Limits on WWgamma and WWZ Couplings from W Boson Pair Production

The results of a search for W boson pair production in pbar-p collisions at sqrt{s}=1.8 TeV with subsequent decay to emu, ee, and mumu channels are presented. Five candidate events are observed with an expected background of 3.1+-0.4 events for an integrated luminosity of approximately 97 pb^{-1}. Limits on the anomalous couplings are obtained from a maximum likelihood fit of the E_T spectra of the leptons in the candidate events. Assuming identical WWgamma and WWZ couplings, the 95 % C.L. limits are -0.62<Delta_kappa<0.77 (lambda = 0) and -0.53<lambda<0.56 (Delta_kappa = 0) for a form factor scale Lambda = 1.5 TeV.Comment: 10 pages, 1 figure, submitted to Physical Review

Search for Large Extra Dimensions in Dielectron and Diphoton Production

We report a search for effects of large extra spatial dimensions in ppbar collisions at a center-of-mass energy of 1.8 TeV with the DZero detector, using events containing a pair of electrons or photons. The data are in good agreement with the expected background and do not exhibit evidence for large extra dimensions. We set the most restrictive lower limits to date, at the 95% confidence level, on the effective Planck scale between 1.0 TeV and 1.4 TeV for several formalisms and numbers of extra dimensions.Comment: 6 pages, 2 figures, submitted to Phys.

Search for Top Squark Pair Production in the Dielectron Channel

This report describes the first search for top squark pair production in the channel stop_1 stopbar_1 -> b bbar chargino_1 chargino_1 -> ee+jets+MEt using 74.9 +- 8.9 pb^-1 of data collected using the D0 detector. A 95% confidence level upper limit on sigma*B is presented. The limit is above the theoretical expectation for sigma*B for this process, but does show the sensitivity of the current D0 data set to a particular topology for new physics.Comment: Five pages, including three figures, submitted to PRD Brief Report

Direct measurement of the mass difference between top and antitop quarks

We present a direct measurement of the mass difference between top and antitop quarks (dm) in lepton+jets top-antitop final states using the "matrix element" method. The purity of the lepton+jets sample is enhanced for top-antitop events by identifying at least one of the jet as originating from a b quark. The analyzed data correspond to 3.6 fb-1 of proton-antiproton collisions at 1.96 TeV acquired by D0 in Run II of the Fermilab Tevatron Collider. The combination of the e+jets and mu+jets channels yields dm = 0.8 +/- 1.8 (stat) +/- 0.5 (syst) GeV, which is in agreement with the standard model expectation of no mass difference.Comment: submitted to Phys.
