Tourism planning is a complex process that includes the involvement of a number of factors during the process of decision-making. Taking into account that any rational planning of tourism should be in line with the principles of sustainable development, which means to preserve the physical and social-geographical attributes of a destination, but at the same time striking a balance with the interests of the local communities, private and public sectors, the use of geographic information systems (GIS) has become an imperative in the process. Tourism is an activity which depends on natural resources, but is also a phenomenon which can have a destructive effect on the natural geographic environment in case of an inadequate access to its planning and development. In addition, during the daily management and operations of tourist facilities, a large number of tourists are a big consumer of energy and water and at the same time produce a significant amount of solid waste, hazardous gases and waste water. These negative impacts of tourism can be prevented or reduced by the application of certain GIS technology in order to achieve sustainable tourism development. This papers main objective is to explore the potential of GIS application in a process of tourism planning and its sustainable development, for the purpose of long-term survival of the tourism destination.

A relatively high number of crashes of vehicles occurs when one vehicle catches up with the other vehicle, so a greater number of traffic and technical expertise is made regarding the circumstances under which these traffic accidents can be prevented. In this work we established the limits of relevant parameters when crashes can be avoided.

The Institute's two goals were the scientific study of crime, on the one hand, and the forensic education of judicial and police personnel, on the other. Due to the influence of its founder, Professor Toma Živanovic, the Institute was provided for, in terms of funding and premises, better than most University institutions. Nonetheless, its scholarly contribution to criminal science was negligible. As regards theoretical approaches, the Institute relied on the anachronistic Lombrosian ideas about the atavistic born criminal, as well as on the contemporary German school of criminal biology. Živanovic's own 'realistic-psychological' theory, which postulated a 'criminal psychological state' (or: 'the criminal soul') as 'the immediate [causal] factor of crime', was never operationalized or empirically tested. The experiments conducted with the Institute's up-to-date and expensive equipment were mostly in the field of electrophysiology, corresponding to the interests of Živanovic's closest collaborator, the Russian-born psychiatrist N.V. Krainsky. The Institute's contribution to the forensic education of police and court personnel may have been more substantial, although no sufficient data on its scope are available. Nothing was preserved of the Institute's laboratory equipment or of its archive.

In this article we considered the extreme temperatures, precipitation and UV-B radiation in Vojvodina region, Serbia. We describe the actual climate conditions for the period 1981−2007 and applied a dynamic downscaling technique using the EBU-POM regional coupled climate model under the SRES-A2 scenario to assess the changes for the period 2021-2100. The results indicate that a warmer and drier climate in the Vojvodina region can be expected at the end of the century. Projection of climate indicates to a strong increase in the mean annual minimum temperatures, and much smaller increase in the mean annual maximum temperatures. The increase of both extreme temperatures is predicted to be the highest in the winter and the lowest in the summer. Mean annual precipitation is projected to increase toward the end of the first half of the 21st century and to decrease for the last 30 years of the 21st century. Precipitation amount will be the highest during the winter and spring. The model simulations show that, by the end of this century, annual mean UV-B dose will recover by 5.2%. Recovery will be faster in the first half of the 21st century and more slowly later on. The UV-B doses recovery is expected to be the highest during the autumn and spring.

This paper investigates current and planned investments in new power plants in Bosnia and Herzegovina and impact of these investments on the energy sector, CO2 emission and internationally committed targets for electricity from renewable sources up to year 2020. Bosnia and Herzegovina possesses strong renewable energy potential, in particular hydro and biomass. However, the majority of energy production is conducted in outdated power plants and based on fossil fuels, resulting in environment pollution. New major investments The Stanari Thermal plant (300 MW) and the investment in Block 7 (450 MW) at the Thermal Plant Tuzla are again focused on fossil fuels. The power sector is also highly dependent on the hydrology as 54% of current capacities are based on large hydro power. In order to investigate how the energy system of Bosnia and Herzegovina will be affected by these investments and hydrology, the EnergyPLAN model was used. Based on the foreseen demand for year 2020 several power plants construction and hydrology scenarios have been modelled to cover a range of possibilities that may occur. This includes export orientation of Stanari plant, impact of wet, dry and average year, delayed construction of Tuzla Block 7, constrained construction of hydro power plants, and retirement of thermal units. It can be concluded that energy system can be significantly affected by delayed investments but in order to comply with renewables targets Bosnia and Herzegovina will need to explore the power production from other renewable energy sources as well.
