Groundwater pollution under the intense of human activities in the Quanzhou coastal area strongly threatens the supply safety of groundwater sources. Based on hydrogeological conditions and the pollution load in this field, the multi-index evaluation method of pollution sources and improved DRASTIC model were employed to assess groundwater pollution risk. The rating and weights of each important factor were determined by expert evaluation method and three-level groundwater pollution risk index were obtained using ARCGIS software. The results show that groundwater pollution risk at the industrial-intensive areas are dominant. So it is necessary for government to control the emmision of pollutant from inducstry in the Quanzhou area.

Groundwater is the principle source of drinking water and protection of groundwater quality is an important issue meets out the increasing population and agricultural practices. The present research an attempt made to develop DRASTIC model to understand the groundwater contamination risk in Ponnaiyar River Basin (PRB), Tamil Nadu, India using geographical information system (GIS). GIS have been shown to be useful tools for assessing groundwater pollution hazard. According to Central Ground Water Board reports the PRB categorized by semi-critical groundwater development. In view of the extensive reliance on this basin, contamination of PRB groundwater became an alarming issue. To assess groundwater contamination risk in the PRB the parameters such as Groundwater depth, Net recharge, Aquifer media, Soil media, Topography, Impact of vadose zone and Hydraulic conductivity were selected. Based on the importance of groundwater contamination all the parameters were assigned to rank and weights. Then all the themes were integrated and classified into five categories such as very low (9.33%), low (26.54%), moderate (34.77%), high (22.38%) and very high (6.98) risk. To validate the DRASTIC model, nitrate concentration was selected and found that it is 81.53% accurate which reflects that, DRASTIC model is appropriate to understand groundwater pollution risk assessment. In the GSB groundwater is contaminated mainly due to extensive use of groundwater extraction for agriculture purpose. Groundwater risk index assessment is an effective tool for groundwater management in the PRB.

The choice of risk assessment procedure is one of the essential stages of efficient structuring of processes on prevention, localization and elimination of the consequences of accidents at main pipeline transport facilities. The authors analyzed themed publications and regulatory documents, governing procedures of risk assessment and forecasting of the consequences of possible accidents, and defined main problems in this area. Procedure for the risk assessment of accidents at main pipeline facilities was developed, the basis of which is the expert evaluation method. The procedure includes the determination of the main criteria for the assessment the probability of accident initiation and development and the evaluation of the severity of its consequences, an expert evaluation of criteria significance, their classification, and creation of a rating for hazardous pipeline sections. The application of the procedure application allows to specify the list of facilities that require high priority forecasting of accidents consequences, thus to optimize the distribution of resources and the overall increase of efficiency in planning while defining forces and special technical devices, necessary for containment and rectification of emergencies. Expert evaluation method application allows considering the specifics of certain enterprises, their technical and technological peculiarities, thereby increasing forecasting accuracy.

The paper presents the main advantages of hydrocarbon-based drilling mud. It is shown that mentioned types of drilling mud are produced both on the mineral and diesel fuel basis and positively impact the overall drilling rate of the wells. Alongside with this, the information on existing complications in the drilling of V and VII horizons of Bulla-deniz field has been generalized, in the context of which improved recipes of drilling mud proposed. Using expert evaluation method, the structural-mechanical and colloid-chemical properties of the drilling mud types have been compared. A new structure for wells of Bulla-deniz field has been offered.

The increasing number of pawnshops working in the shadow economy has been an important problem in Russia for several years. The paper investigates the dynamics of the number of registered pawnshops, the reasons for the toughening of their AML/CFT regulation and analyzes the further development of the industry. Based on the analyzed data, the forecast of the number of registered pawnshops up to 2020 is compiled using the consolidation of the moving average methods and the analytical trend alignment, as well as the expert evaluation method. The main methods of pawnshop activity regulation have been analyzed and an expert evaluation of the effectiveness of their implementation has been carried out. The results obtained during the study allowed the authors to formulate a hypotheses on increasing the effectiveness of the methods under consideration, as well as to offer their methods for regulating the activity of pawnshops in the field of AML/CFT. Keywords: AML/CFT, "gray" pawnshops, non-credit financial organizations, high-risk activities, the Central Bank of the Russian Federation, internal control rules.

Artistic Image

The paper describes the problem of the uncomfortable use of a computer manipulator, based on various ergonomic indicators among users. The analysis of aesthetic and ergonomic parameters in similar product models. Three artistic images of a computer manipulator thematically related to the main function of the designed product were selected. For each artistic image, a conceptual design of the product body was created. Using the method of expert evaluations, design professionals determined the most promising outline solution of the case in terms of aesthetic qualities and compliance with the main function of the product. An experimental prototyping of the design object was carried out using sculptural clay and foam, followed by expert evaluation and refinement of the shape of the body of the product and the location of the components. The result of the study was a mock-up of a computer manipulator with a bionic shape. The object has a spectacular appearance due to the bright image of a stylized fish, and also corresponds to aesthetic and ergonomic parameters.
