The Role, The Importance and the Perspectives of a CEFTA Free Trade Zone

A characteristic of the contemporary world scene is a market that does not recognize traditional, time and geographical limits. Creating new market rules, the economic organizations integrate, and the products and services internationalize and go out of their own locality. The product of this attitude is the opening of the national borders. In this way, the national economies are merging into regional organizations of economic character. In the sphere of globalization of the world economy, there is more and more urgent need for the inclusion into the world economic developments of all countries that are market oriented. The particular is the need for an intensive exchange of goods, services, labor and capital. For all the countries of South-Eastern Europe, including Serbia, the main challenge is to join the European Union. The challenges are primarily in the harmonization of customs and other policies, the institutions, as well as the adjustment of the economies of those countries, mostly in transition, to a liberal market economy principle. Market liberalization brings many benefits to trade, such as the abolition of import and export taxes, free flow of goods and capital, the abolition of monopoly and increasing of competition brings lower prices and higher quality of products and services for final customers. Just CEFTA or Central European Free Trading Agreement, represents an agreement of the Central European free trade agreement. Its main role is to prepare the signatory countries to join the European Union

Main Characteristics and Trends in Contemporary International Economy

For the last hundred years the number of the countries in the world is even quadruplicated, so that from fifty countries then, the number is increased up to about two hundred countries. The countries appear and disappear, some are developing while other are regressing, and thus they have influence on changing the picture of the world`s economy. In this work will be presented the development of the world`s economy, as well as its features, economic status of the countries in the region, the globalization as a challenge for the world`s economy to face, and at the end the comparison of Serbia and its status in the world`s economy on international economic scene

Impact of Global Economic Crisis on Development of Serbia

The global economy is in the middle of across-the-board crisis, which started on real estate market, spreaded through unregulated financial system and led to crisis of credit market and later to crisis of employment. Up today it developed in complex vicious circle, with the price drop of real estates and the growth of unemployment together with the struggle against the crisic of credit market. This crisis spreads equaly to developed as well as to undeveloped countries, and thus didn`t go round Serbia. When economies start to recover, there must not be return to usual way of business. The new national and global strategy is needed which would restore the financial markets and their main function of providing the stable and payable financing of productive investments in real economy. Beside this, there is need to establish the new model of economic development which would be economically effective, socially rightful and ecologically sustainable

Zinc concentration in woody and herbaceous plants at Kosmaj area, Serbia

In the paper, the content of heavy metal (Zn) in plants of Kosmaj area was analyzed. Concentration of Zn was measured at four locations, in vegetative parts - leaves of ten plants (eight of them were woody plants and the other two were herbaceous plants). Results showed that samples of plant material from all locations are not contaminated with heavy metal and, at the same time, the results show lack of Zn at some locations, as well. It is important to emphasize that Zn does not endanger the area of Kosmaj

Iron (fe) content in vegetation cover of the natural protected area Kosmaj, Serbia

This paper analyzes the iron (Fe) content of the vegetation at the beginning of the vegetative cycle for the period 2012/2013. Heavy metal content in the vegetative parts of ten plants (eight types of woody plants and two types of herbs) was analyzed in four locations. Iron (Fe) is a biogenic element present in plants in relatively small quantities. However, its ability to produce chelates, as well as being polyvalent, assorts it into a group of elements which have a significant impact on many physiological and biochemical processes. The analysis of iron content in leaves of woody plants and herbs growing in the natural protected area "Kosmaj" has shown that depending on location the iron concentration, in statistical terms, significantly differs and ranges from A to I in locations 1 and 3, whereas its concentration ranges from A to J in locations 2 and 4

Concentration of heavy metals and stand state of sesille oak (quercus petraea (matt.) Liebl.) On avala mountain (Serbia)

The research of heavy metals contents in soil and leaves of Sessile oak (Quercus petraea (Matt.) Liebl.). Moreover, the paper presents the analysis of the stand state on the Avala Mountain. The Avala area is high-grade protected natural resource located on the territory of Belgrade (Serbia) and its regime of exploitation and protection is clearly defined. It is assumed that the human factor is the primary cause of degradation of the protected areas of Avala. Therefore, the current inadequate stand composition and the impact of traffic pollution can be considered the decisive causes of degradation on mountain, as a natural area under special protection. Determining the degree of loading of soil and plants with heavy metals and the analysis of stand conditions of such valuable protected areas such as the area of Avala, are of great importance, based on the results obtained, to take appropriate timely precautionary measures, in order to preserve, improve nature conservation, the environment in general, and especially health conditions. The research of the contents of heavy metals (Pb, Ni, Fe, Zn i Mn) in soil showed the load of soil especially with Pb and Ni. In third locaction the concentration of Ni (amounting to 7.0 mu g/g) in the plants leaves is significantly higher which indicates the existance of chemical contamination of soil, before all, with this pollutant. The measured concentrations of all examined heavy metals (Pb, Ni, Zn, Mn and Fe) in the leaves of Sessile oak on Avala fall within the maximum allowed values in accordance with the legal regulations in Serbia
