SUBSURFACE ARCHITECTURE OF NEOGENE LOWER SARMATIAN STRETAVA FORMATION IN THE SELECTED PARTS OF THE EAST SLOVAKIAN BASIN
Igor Ďuriška

The main aim of this paper is to show the subsurface architecture of the Lower Sarmatian Stretava Formation in the studied areas of Prešov and Trebišov depression which can be used for both paleogeographical studies and estimation of the hydrocarbon potential of this formation. Study is performed in the Schlumberger‘s Petrel seismic interpretation software. The reflexes building Stretava Formation are showing mid to high amplitude and mid to low frequency and are in certain parts of basin discontinuous. The well SP data are showing that several sea transgressions and regressions occurred during the sedimentation of Lower Sarmatian deposits.

RECYCLING OF WASTE CONTAINING TUNGSTEN AND ITS RECOVERY
Klaudia Šándorová

This work deals with the recycling of waste containing tungsten. The importance of this work focuses mainly on the sources of tungsten waste originating from individual industries. The largest share of tungsten consumption is in sintered carbides. As a result, tungsten waste is the largest source of tungsten. The choice of recycling technology depends on the type of tungsten waste, its purity and the desired end products. The individual methods of recycling are analyzed in terms of feedstock and product obtained. The positive effect of the dimensional reduction of waste before the oxidation process in chemical methods has been confirmed. There are also significant processors of waste containing tungsten.

THE PROPOSAL ON EDUCATIONAL THEME PARK FOR LOCAL TOURISM DEVELOPMENT
Dana Tometzová, Barbara Hlavňová, Pavol Rybár

The aim of this paper is to provide new opportunities of geotourism development in areas that are very attractive from the tourist point of view but their infrastructure and superstructure is not developed yet. The paper contained a proposal to create an educational and amusement theme park along with a description of its spatial and functional use. Visualization of theme park was
created by using SketchUp application, in the same way was created also video visualization. The proposal consists of 3D projection hall, playground, exhibition of prehistoric animals, mining exposition and a thermal pool that includes indoor and outdoor section. Proposed educational theme park is designed to improve the local tourism market and stimulate further economic development.

ANALYSIS OF THE PRODUCTION COSTS IN MICRO, SMALL AND MEDIUM-SIZED ENTERPRISES IN SLOVAKIA
Tomáš Pavlik, Martina Vasilková Kmecová, Dominik Tudoš

In the mining industry in Slovakia, we can state that micro enterprises, small and medium-sized enterprises are the largest companies by size category. The sector of small and medium-sized enterprises in Slovakia is experiencing dynamic growth. In the business economy they are more than half of them involved in creating value added, providing jobs for almost three quarters of an active workforce. From this point of view, these enterprises contribute to a great extent to the positive economic development of the landscape and to the competitiveness of Slovak enterprises.
Every activity of mining enterprises belonging to this sector creates direct jobs. They are linked to about three times more jobs in supplier organizations and in service activities. It is therefore very important to keep track of costs and their financial management to keep mining companies and their further progress. Another reason is the fact that the very cause of a business failure is the excessively high costs of the mining companies or their insufficient management. The objective of structural cost analysis in mining enterprises is to point to the kind of costs that are most burdensome for businesses. This article is based on data from the Slovak Republic study carried out at national level from 2013 until 2016 as well as on the costs of mining enterprises processed in the context of cost research for all mining activities of enterprises in the Slovak Republic.

GENERALIZATION OF THE FIRST AND SECOND PROBLEM IN GEODESY
Sebahattin Bektas

We aim to show how to generalization of the first and second problem in geodesy. In this paper we study basic geodetic problems (First and Second problem or Direct and Invers problem) on a triaxial ellipsoid, a rotational ellipsoid and a sphere. When we look at the studies related to the subject, it seems that the solution of the direct and invers geodetic problems with geographical coordinates on the triaxial ellipsoid is very difficult. In order to overcome this difficulty, in this work, we made the direct and invers problem with Cartesian coordinates instead of geographical coordinates. We will also use slope length that directly connects two points instead of the geodesic curve length. We think that our choice is also meaningful at the same time. This is because the geodesic curve lengths can not be measured with the measuring instruments and can not be applied to the ground, while the slope lengths can easily be measured with modern measuring
instruments and can applied to the surface. In addition to we will see how to solve the conversion between the geographical coordinates with Cartesian coordinates or vice versa on triaxial ellipsoid.
