Our paper is result of the research done in a special direction for solving problems of physics by using GeoGebra programme: calculation of centroid. Lots of simulations of physical phenomena from the class of Mechanics can be performed and computational problems can be solved with GeoGebra. GeoGebra offers many commands and one of them is the command “centroid” to calculate the coordinates of the centroid of a polygon but, we have created a new tool to calculate the coordinates of the centroid of a plane region bounded by curves. Our work is part of the passionate work of many GeoGebra users which will result with a very rich fund of GeoGebra virtual tools, examples and experiences that will be worldwidely available for many teachers and practioners.

This paper focused on an experimental works that have been performed to examine the young’s modulus of foamed concrete at elevated temperatures up to 600°C. Foamed concrete of 650 and 1000 kg/m3 density were cast and tested under compression and bending. The experimental results of this study consistently demonstrated that the loss in stiffness for cement based material like foamed concrete at elevated temperatures occurs predominantly after about 95°C, regardless of density. This indicates that the primary mechanism causing stiffness degradation is microcracking, which occurs as water expands and evaporates from the porous body. As expected, reducing the density of LFC reduces its strength and stiffness. However, for LFC of different densities, the normalised strength-temperature and stiffness-temperature relationships are very similar.

Since the 1980s, globalization has led to a rapid increase in the growth of foreign direct investment (FDI) all over the world. Mongolia for more than a decade has been in the process of radical transformation and has taken significant steps to build a market-based economic structure. Foreign Direct Investment plays a very important role in achieving rapid economic growth in the developing countries. This can be achieved by taking advantage of available mobilizing domestic savings, foreign capital, technology transfers, establishment of new premises and favorable foreign policies It is now widely acknowledged that FDI has potential benefits that can accrue to developing countries. This view is mainly based on the neo liberal and development economists. They suggest that FDI is crucial for economic growth as it provides the much needed capital for investment, increases competition in host countries economies, and helps local firms to become more productive by adopting more efficient technology or by investing in human or physical capital [1]. FDI is also said to contribute to growth in a substantive manner because it’s more stable than other forms of capital flows. This paper investigates the key drivers of foreign direct investment (FDI) in Mongolia.

The study of the media culture, the virtual world requires human knowledge and skills analysis of media texts of different levels of complexity. The article explains the technique of analysis of media texts detective-fiction genre as an example of the screen adaptations of A.N.Tolstoy (1883-1945) novel – "The Hyperboloid of Engineer Garin" (1927) in the context of media education. The author believes that the technology fits into the basic range of media education goals of higher education (especially in the training of future cultural studies, art historians, sociologists, linguists, psychologists, teachers).

In the paper differences between sign-oriented representation and symbolic representation are discussed. The study explored perspectives of using symbolization to teach young schoolchildren the mathematical concept. The author recognizes relevant (that allows the proceeding to sign representation) and irrelevant symbolization. The three groups of young schoolchildren (N=49) were taught the mathematical concept of a function using different programs: traditional, employing sign representation and two experimental – based on relevant and irrelevant symbolizations. The experiment demonstrated that symbolic representation can facilitate mastering of the mathematical concept of a function if the content of symbol possesses structural interrelations that could be converted into sign form.

Relevance of the research of modern climate change is beyond all doubts at the moment. Climate is, first of all, a significant share of any country’s resources. Losses due to global climate change can affect virtually all branches of economy and social aspects, including energy production, eco-systems, agriculture, forests, construction, transport, tourism etc. Climate change imposes certain mode of economy, a strategy of economy’s development years ahead. According to forecasts, for example the one of European environmental agency (EEA), one of the first “hostages” of climate change will be winter tourism and alpine skiing resorts. Climate change seriously influences incomes of countries and certain regions located in mountain areas and developing winter sports. Yet, forecasts of climatologists on modern climate change trends are ambiguous and sometimes controversial. For this reason definite scientific and practical interest is raised by research in climate change trends in mountain areas based on mostly state network of meteorological stations.
