Serbia is traditionally a wine-growing region and it is slowly approaching those countries that have benefited from the development of this type of tourism. The subject of this paper is the analysis of the Trstenik vineyard district, whose wine -growing areas, although within a small municipality in Central Serbia, are one of the largest in the country within the Three Morava Rivers region. The Trstenik vineyard district can take a chance and find its place in this specific tourism market. The aim of the paper is to present all the strengths and opportunities, but also the threats and weaknesses for the development of wine tourism in this wine district. This is presented through SWOT analysis. All the results could be used to make this municipality as wine tourism destination in Serbia.

We report a case of paraneoplastic dermatomyositis associated with metastatic rectal adenocarcinoma and lethal outcome, and suggest a comprehensive evaluation of patients with dermatomyositis older than 50 years in order to exclude or verify the occult malignancy.

' Vilém Flusser 0.0 Premise // Vision Digital vision, Sean Cubitt writes, begins with a withdrawal of the eye. 1 The machine, on which we are ever so increasingly relying for visualising the world, self-evidently, does not and cannot see in the same manner as the eye, and this factual situation determines the status of our now predominant vision. The machine continues to collect, compare and assemble visual data, but the articulating role that the eye performed in the past is now taken over by 1 Sean

In this paper, using simulation in the software OptiSystem 7.4, the FSO (Free Space Optical) system operating at wavelengths of 850 nm, 1315 nm and 1550 nm was observed. The influence of different levels of atmospheric turbulence and link distance on the signal transmission quality was investigated. The Q factor and BER (Bit Error Rate) were used as a measure of quality. The changes of the Q factor depending on the observed system parameters are graphically shown. Eye diagrams and signal spectrum are also given. The analysis of the results shows how the quality of the received signal changes due to different atmospheric phenomena at certain distances from the transmitter.
