THE ANALYSIS OF METHODS OF INFORMATION QUALIFICATION IN INTERNET DURING SOLVING PROBLEMS OF INFORMATION SEARCH
Due to the fact that the Internet stores a large amount of information must be used effective methods of search. The characteristics inherent in job search, are the completeness, reliability and high speed. These characteristics can be achieved with the use of appropriate methods of classification. The article considers several approaches. The cluster method is based on partitioning elements of the set into groups. The distance between the elements is set to metric. Linguistic analysis based on the ability to extract information from the text. The scheme of linguistic processing. Statistical approaches proceed from the specific patterns frequency of the meeting words. Symptom analysis is the study of the morphemic, morphological and syntactic features of words and sentences in the text. Semantic analysis is the analysis of the text concerning the meaning of the words inside it. The combined approach involves the use of several of the above approaches in tandem, series, or parallel, to increase the accuracy of the analysis. Depending on the emerging challenges, will be useful for the appropriate method of classification.

MICROSTRUCTURAL CHANGES OF DENTAL POLYMERIC FILLING MATERIALS BY THE ELECTROMAGNETIC FIELDS FOR ITS PHYSICAL AND MECHANICAL IMPROVEMENT
А.А. Kunin, N.S. Moiseeva, V.M. Popоv
It is well-known that restorative filling materials used for treatment of dental caries consist of various components including synthetic monomers or low-molecular polymers, playing an important role in the formation of the main structure of these materials and characterizing their physical and chemical properties. The necessity of variation and improvement in structural characteristics of polymeric dental filling materials by the electromagnetic fields for its physical and mechanical improvement served as the initiating factor of our research.
According to the research purpose and challenges, we studied the microstructure of fillings and bonding materials, investigated their physical and mechanical properties before and after the electromagnetic field influence.
The obtained data analysis shows the microstructural changes in physical and mechanical properties of polymeric filling materials after the electromagnetic field exposure, including condensation of the material microstructure according to the results of scanning electron microscopy and an increase in their physical and mechanical strength properties.
Keywords: dental polymeric filling materials, electromagnetic field, scanning electron microscopy, physical and mechanical properties, descriptive statistics.

Insomnia is one of the contributing factors for COPD. The study included 28 people with stage II COPD diagnosed with sleep quality disturbances that against the background of traditional therapy of COPD received within 12 months of 4 courses for 14 days melatonin 3 mg 30-40 minutes before bedtime. As a result, significantly improved performance psychological quality scale component life and improved quality of sleep. It was developed to an algorithm specialist tactics in patients with stage II COPD. In view of the findings can suggest the following modification of the algorithm expert tactics. The algorithm includes the first phase of clinical and instrumental examination in accordance with the GOLD criteria and evaluation of the quality of sleep. If the patient has a diagnosis of stage II COPD and sleep index exceeds 9 units, it becomes expedient administration of melatonin 3 mg 1 time per day (14 days) on a background of standard therapy of COPD.
Keywords: COPD, melatonin, insomnia, quality of life, algorithm.
ONE-WAY ANALYSIS OF VARIANCE OF SOME FACTORS INFLUENCE ONTHE SLEEP QUALITY IN COPD AND UNDER MELATONIN ACTION

Оne-way analysis of variance revealed the negative impact of gender, age, duration of disease, nicotine addiction, the number of hospitalizations and the number of exacerbations with an appeal to the person skilled in the year, the level of anxiety and depression, TSHH the quality of sleep in patients with moderate development of chronic obstructive pulmonary disease (COPD). Acceptance of melatonin (the scheme) patients with moderate COPD leads to statistically zanchimomu improving sleep quality, reduce the number of exacerbations with the call of a general practitioner, emergency medical care and hospitalization in the background to improve the psycho-emotional sostoyaniya.Odnako this regimen of melatonin in patients with severe COPD does not lead to effective correction of sleep disorders.

ON THE IMPLEMENTATION OF THE CONCEPT OF RECURSIVE-PARALLEL PROGRAMMING
Mohammad Mohammad Ibrahim, A.V.Danilova
The paper discusses the features of the recursive-parallel programming. Its main advantage is the ability to use the potential parallelism of the algorithm, independent of the original data. Another important advantage – the ability to ensure an effective dynamic load balancing of processor modules (PM) during program execution. Thus an application programmer need not know anything about the number and performance of PM included in the computing system. The only requirement that must be met by program is that in a short time the work must be divided into a sufficient number of independent fragments of the same volume and appropriately decorated. For a fairly wide class of problems splitting the work into two equal (or almost equal) fragment is easy.
