  Today in Russia, unfortunately, the science is one of professions, is far not so popular, as the lawyer, the financier or the programmer. At the same time competitiveness of modern economy depends both on separate scientific and technological achievements, and on technologies of management of an innovation in the various countries. The review of experiences of innovative development is presented in this article abroad in such countries, as the USA, China, Finland and South Korea. Innovative development of these countries conducting economically will be rather interesting to CIS countries where need of such development is an essential task.

The question of system analysis and risk management for public health is important and requires a thorough study. As part of its study on chosen method has been implemented an algorithm for estimating the risk of isolated effects of air pollutants on human health, then conducted a systematic analysis of the results, and management solution put forward to improve the safety and health of Taganrog. Based on the data of automated monitoring system has been established that the risk of adverse effects in humans with daily admission of matter in life is insignificant, and this influence is characterized as acceptable.

  The problem of air quality control is relevant at the present time. There are a lot of different devices and methods of air monitoring. The promising devices for air monitoring are automated air monitoring systems functioning in real time regime. The basic part of such system is a chemical gas sensor. Gas sensors can be combined into the arrays or so called multisensory systems to increase their effectiveness. Sensor arrays using semiconductor sensors based on SiO2CuOx, SiO2SnOxCuOy, SnOxZrOy, silver-polyacrylonitrile thin films made at department of chemistry and ecology have been investigated in this work. As a result of sensors signals processing gas recognition technique has been developed. The recognition of ammonia, nitrogen dioxide, chlorine has been made.

  Stability of sensors on the basis of inorganic oxide materials is one of the primary goals by working out of atmospheric air control devices. In this work long-term stability of a sensor response on the basis of the SiO2SnOxCuOy material to carbon oxide (II) exposure in a range of concentration 1-100 ppm is studied. It is shown that the sensor response differs high stability and reproducibility. Continuous heating within 21 days to working temperature (350°С) influence its value negligibly.

  We have investigated electrical and gas sensitive properties of gas sensor based on carbon nanotubes (CNT) and carbon nanotubes modified by metal oxides (such as tin oxide and silicon oxide).  Also we  have find out that modification of  CNT by  metal oxides helps to  improve film`s adhesion to substrate, decrease electrical resistance, recovery time, working temperature , enhance gas sensitivity in comparison with sensitive elements based  only on CNT or metal oxides. Moreover experimental results showed that properties of composite material depend on concentration correlation of solutions. As a result we can get highest sensitivity of sensor element by choosing optimal relation between concentrations of solutions.

  Technology of fabricating unheated gas sensors based on polyacrylonitrile (PAN) using different temperature and time modes of a two stages IR-pyrolyze is developed for the remote control of the human condition. Gas-sensing elements based on PAN films and cobalt- and copper-containing PAN films are fabricated. Gas sensitive characteristics of the gained samples to CO, Cl2 and CHCl3 in atmospheric conditions are determined. We have found that gas-sensitivity of the samples depends on the composition of the original film-forming solution and on the process parameters of fabricating the film material. Moreover the samples show sensitivity and selectivity at room temperature. The benefits of this study is that films based on PAN and metal-PAN are the most promising material for electronic engineering including gas sensors for the remote monitoring of the human condition.
