It is generally believed that chronical infections of mucous coat and skin in most cases occur under some quantitative deviations of key cell parameter of immune system and (or) functional insufficiency of separate cells. For example, hemophage. It was established in previous works that local immunity factors in earwax are defined rather distinctly and in some cases their quantitative deviations are associated with clinical manifestations of external otitis. Along with that, information on the immunity factors state at recurrent external otitis is not enough to define the roles of different chains of immune system in pathogenesis of external otitis. For the purpose of expanding the understanding of the external otitis pathogenesis factors and establishment of effective approach to treatment order we studied the state of some system factors of immunity in peripheral blood at patients with external otitis in remission and in process recrudescence.

Introduction: Implant failure is the most frequent complication after sur-gery for large bone defect. Mathematical modelling and finite element method allow and show the mechanical features of the interaction between femoral bone and endoprosthesis after distal femur replacement. The stressedly-deformed condition of the distal femur endoprosthesis depends on the angle of inclination and the length of intramedullary stem and the level of the femoral bone resection. Material and method(s): The finite element method for three-dimensional model of the femur was used. This model was created in the form of 3D object with the reconstitution of anatomical features of the proximal and distal ends of femoral bone. The prototype was the teaching specimen as a freeze-dried native male right femur. The model reproduces of anatomic features of the bone shaft - back crista and antecurvation. There are two parts: the first one (external) had mechanical properties of cortical bone, the second one (internal) had characteristics of trabecular bone and had form of a hollow rod. For further studies distal end of the femur model was removed and bone defect was replaced by implant. Three variants of the model have been developed to study the mechanical features of implant-femur interaction. The models reproduced bone defect replacement by implants with different values of inclination angle between the upper and middle parts of the implant. Investigation of the stressedly-deformed condition was realized under load bearing with 0°, 30°, 60° and 90° of the inclination angles between hip and knee joints load lines. Intramedullary stem lengths were 80, 110 and 140 mm and the lengths of prosthesis body were 96, 196 and 296 mm as well. Result(s) and Conclusion(s): Maximum stresses arise in the intramedullary stem along its entire length and load peak is localized in the base of intramedullary stem. The bone resection stress concentration is observed in 5° inclination angle of intramedullary stem and the endoprosthesis body. The angle between implant body and stem has to be selected individually in the range from 1 to 4 degrees for optimum performance. Stress rate is inversely proportional to the stem lenght. Stress rate is observed in great trochanter zone when the end of the intramedullary stem is in intertrochanteric area. The prosthesis stem should not be shorter than 100 mm. The end of it should not be placed in the intertrochanteric area. Significant increase stress rates in intramedullary stem and femoral shaft are observed with the distal third resection of the femoral bone. Zone of maximum stress rates moves from bone shaft to prosthesis body when level of femur resection is on upper and middle thirds of it. It drives to the overall reduction of stress rates regardless of weigh bearing angle of knee joint.

Urgency of technical inventions in economy grows every year. This article explains the essence of an invention, its novelty, practical significance. A system of managing multiple variable data on consumer product characteristics consists in modeling a list of system sequences that consists of 6 stages. Every stage includes its own stages, operations, and tools of data management, but they are connected and united into an integrated system with a common scheme and have their contribution in the achieved technical result. A technical result of an invention consists in increasing effectiveness, reliability, and accuracy outcome data for situational-strategic of the product program. Coordination of strategic and current programs in order to achieve situational balance between supply and demand will lead to an increase not only economic but also social efficiency.

The role of government is to create an enabling environment across all sectors e.g. health and commerce. This is achieved by policy frameworks, from which emerges legislation and regulation. The same is true for digital transformation. A World Bank report argues that digital revolution needs offline help to realise its potential that include implementing policies that provide an enabling environment for inter alia infrastructure development and the creation of services. Whatever the path that countries and organisations choose towards digital transformation, what is clear is that this is journey that must be embraced sooner rather than later.

Over the entire period of market reforms commodity structure of foreign trade and domestic production structure of Tajikistan has not changed since independence, reflecting the slow progress of structural and economic reforms initiatives. Exports of cotton and aluminum continue to generate about half of GDP and two-thirds of the annual foreign exchange earnings and a quarter of tax revenues. The asymmetry between the country import and export trends experienced in Tajikistan in recent years, tends to increase. Geographical location of Tajikistan and the underdeveloped transport links, coupled with weak regional trade ties strongly influence on the structure of foreign trade.

The ancient settlement of Penjikent is located near the modern city of Panjakent (Sughd Region, Republic of Tajikistan) on the second terrace above the floodplain of the Zeravshan River, in an oasis, bounded from the north and south by two mountain ridges – Turkestan and Zaravshan. This area is very convenient for agriculture, people mastered here since ancient times.

Bio-technical revolution has actually started since the XX century last decade and created a powerful wave of innovative products and services in medicine, agriculture, power engineering, i.e., practically in the majority sectors of the global economy. At the beginning of the XXI century EU has developed “Strategy For Europe On Life Sciences And Biotechnology”, which has become a basis for EU countries to develop their national policies in the sphere of biotechnologies [1]. That document recognizes that after the information revolution and Information-Communication Technologies (ICT) development biotechnologies and life sciences have become the second innovation wave.

‘Miles to go and a lot to achieve’ After completing his MBA in 1985 from one of the top 10 management school IMT Ghaziabad, Sanjeev worked with a few good national and international companies and did quite well there in terms of achievement. He was always a blue-eyed boy of the management as he was rendering good results and adding to profitability. Soon he realised that job was not for him because he never used to like subordination by others. Though he never showed it and it was never reflected in his behaviour or action, there was a hidden desire in the deep recesses of his heart to be ‘on my own and be my own boss’.

Little is known about perceived self-efficacy of preschool teachers, their perceptions of preschool excellence, or the relations between the two. There were three purposes for this research: defining the professional self-efficacy of preschool teachers (PTSE); defining preschool teachers' perception of preschool excellence (PTPPE); and investigating the relationship between the two. Scales for PTPSE and PTPPE were developed especially for this study. Preschool teachers (N = 202) participated during the 2013 school year. Structural Equation Modeling was performed to test the fit between the research model and the obtained data. PTPSE scale (α = 0.91) was comprised of three subscales: pedagogy (α=0.84), organization (α = 0.85) and staff (α = 0.72). The PTPPE scale (α = 0.92) is also composed of three subscales: organization and pedagogy (α = 0.88), staff (α = 0.84) and parents (α = 0.83). The goodness of fit measures were RMSEA = 0.045, CFI = 0.97, NFI = 0.89, df = 173, χ²=242.94, p=.000, showing GFI = 1.4 (<3) as a good fit. Understanding self-efficacy of preschool teachers,preschool excellence and the relations between them could assist policymakers with decisions concerning continuing professional development (in service training) of preschool teachers.
