The purpose of the study is to estimate of probable predictors for the probable predictors of knee joint osteoarthritis progression in X-ray negative stage based on ultrasound examination. The sixty five patients with X-ray negative gonarthritis were selected into the study. Both X-ray and ultrasound examinations were performed for each of the patients (before the study and since one year). The authors determined degeneration of the medial meniscus and articular surfaces roughness had the most degree of sensitivity (91%), and cartilage thickness of medial joint parts (86%). The degenerative changes of the posterior cruciate ligament had the lowest sensitivity (42%), and degeneration in the lateral meniscus (47%). During the regression analysis only two quality indicator such as cartilage thickness of the medial parts, and articular surfaces brought significant contribution to the risk prediction of the osteoarthritis progression (odds ratio=22.7 and 71.4; p=0.018 and 0.002, respectively). The degeneration in the anterior cruciate ligament was not significant for the model (odds ratio= 26,3; p=0.05).

In article the furniture market in modern Russia and the world tendencies connected with this mar-ket is considered. In article modern factors of risks are classified, the main tendencies which negatively influence development of the furniture market during the present period are analysed. In article tendencies of development of the furniture market according to statistical sources are analysed. Indicators of development of the furniture market of Russia during recession are especially revealed. Because envi-ronment plays a significant role in development of an enterprise network in the furniture market, it caused instability of its existence.

The paper presents the results of study of the clinical and functional characteristics of chronic obstructive pulmonary disease III degree. The peculiarities of hormonal status by determining the hormones as cortisol, aldosterone, DHEA-S are revealed. At the correlation determining of hormone levels with clinical signs it was established significantly lower levels of cortisol, aldosterone, and DHEA-S at severe and very severe dyspnea in patients with COPD III degree. The use of low-intensity laser radiation in the treatment of patients with chronic obstructive pulmonary disease improves clinical features and laboratory data on improved hormonal status, including significant increase in cortisol, aldosterone, DHEA-S, and reduces the duration of acute illness and financial expenses in the inpatient treatment of patients, improves the quality of life in patients with chronic obstructive pulmonary disease. Correlation analysis showed the presence of multiple linear relationships between hormone levels and clinical signs. Correlation between levels of cortisol, aldosterone, and DEHA-S with the main clinical laboratory and functional indicators of COPD was defined. It was found that reducing the concentration of hormones is accompanied by varying degrees of severity of the deterioration of clinical, laboratory and functional parameters that determine the severity of the disease. The proposed method of hormone therapy is effective, safe, well tolerated and doesn’t cause side effects. The data on the effectiveness of complex treatment can be used in treatment, clinical examination of the design of programs, prevention and rehabilitation of patients with COPD.

A retrospective analysis was carried out on the basis of epidemiological indicators such as prevalence and incidence for diseases of the musculo-skeletal system and osteoarthritis among residents of Arkhangelsk region and Krasnodar region. The incidence trends to increasing for diseases of bones and joints during the period of 2000-2012 years showed (in the Russian Federation for 13 years of growth was 8%, in the Arkhangelsk Region - 31%, and the Krasnodar Region- 142%). The similar results were obtained in studies for osteoarthritis (in Russia increase by 55% over 13 years for 41% of the Arkhangelsk Region, Krasnodar Region - 46%). Maximum growth indicator prevalence of diseases of the musculo-skeletal system was observed in the Krasnodar region and was 69% and in the Arkhangelsk region - 30%, in Russia on average increase was 26%. For thirteen years also marked increase in the prevalence of osteoarthritis in Russia as a whole and in the Arkhangelsk region and the Krasnodar region. Environmental and climate and geographical features of investigated regions can cause the detected differences.

The article proposes to applyduration and volatility rates, traditionally used to analyse financial risks, to estimate risk indexes of investment projects, and defines these rates’ main advantages.
