In this paper, a new fuzzy-behavior-based algorithm for roundabout intersection management is presented. The algorithm employs cooperative intelligence and includes intelligent vehicles and infrastructure to calculate speed profiles for different vehicles, in order to achieve more comfortable driving profiles, as well to reduce congestion and CO 2 emissions. The algorithm uses adaptive spatio-temporal reservation technique and was tested in MATLAB/Simulink environment. The algorithm is designed to function in different scenarios with both cooperative and non-cooperative vehicles, as well as optional intersection infrastructure. Results have show that using the proposed algorithm different vehicle communication types can be successfully combined in order to increase traffic flow through roundabout intersections.

Every citizen of the Republic of Serbia has another opportunity to invest and increase their income - investment funds. The first funds began its operations shortly after adoption of the Law on Investment Funds in 2006 which provided legal framework for their establishment and doing business. The initial years of business were marked with negative influences as a result of great crisis within world markets. The main reasons for limitation of greater investment of individual investors in investment funds are both low standard and financial status of citizens of Serbia, underdeveloped national economy, underdeveloped financial markets and consequently, low and negligible investment funds' income.

The prospective study, which took place from February 2011 to March 2014, included respondents who were sent for computerized dermoscopy because of non-melanocytic skin tumours. Respondents were divided into 2 groups. The first one, group A (45 respondents), consisted of respondents who had expressed concern about the observed changes in the skin and the desire for examination. The second one, group B (50 respondents) were respondents that did not come for examination due to changes on the skin, but for other reasons, so they had indirectly detected suspicious skin lesions. The aim of this study is to analyse the importance of early suspicion of non-melanocytic malignant skin tumours by specialists in primary and secondary health care. Parameters for comparison were respondents' subjective attitude of non-pigment skin lesions and dermoscopy and/or PH findings. It has been shown that changes in the skin that bleed are sometimes highly suspect of NMSC because group A had 5 such cases and NMSC was detected in 4 cases, and group B had 7 respondents with haemorrhage and there were 4 with NMSC. In group B, out of 12 respondents who said that they had found suspicious skin lesions caused by trauma, there were 8 NMSC, while in group A there were 3 cases, which is a statistically significant difference. In group B, out of 16 respondents who claimed that they had had suspicious skin changes dormant for years, NMSC has been proven in 3 cases, and in group A there was not NMSC which is also a statistically significant difference. It was confirmed that the claims of the respondents are unreliable and that all patients should be addressed to computer dermoscopy, in patients with visible changes that arise even a slightest suspicion of NMSC.

The prospective study, which lasted from February 2011 to March 2014, included respondents who were referred to computerized dermoscopy due to melanocytic skin tumours. The respondents were divided into 2 groups. The first one, group A, (38 respondents) consisted of respondents who had personally expressed concern about the existing pigment changes on the skin and had desire for examination. The second one, group B, (40 respondents) consisted of respondents that did not come for examination due to changes on the skin, but for other reasons, but suspicious skin lesions were indirectly detected. The aim of this study was to analyse the importance of early suspicion of melanocytic malignant skin tumours by specialists of primary and secondary health care Parameters for comparing the results were respondents' subjective attitude to pigmented skin changes, as well as dermoscopy and / or PH finding. There was no statistically significant difference between groups in terms of respondents' attitudes to pigmented skin lesions, i.e. fear of skin changes, the belief that moles should not be touched (operated on), or that pigment changes that they have since birth are not dangerous. Early suspicion of melanoma in Group B resulted in detection of 4 nodular melanoma and 3 superficial spreading melanoma, while in group A there were no malignant skin lesions, which is a statistically highly significant difference. It was confirmed that early suspected melanoma and referring patients to dermoscopic examination had advantages as working principle in any clinic or any specialty.
