Title of article: Laser scanning optimisation process in mountainous terrain
Author: Mária Mrázová
Abstract: Digital terrain model is applicable for many possibilities related to aerial works by use of photogrammetry or laser scanning of the earth’s surface. For the purpose of this research we consider just laser scanning used for work in difficult mountain terrain. The terrain of the Slovak Republic has many high hills and it signifies more complex flight planning, as laser scanning is usually flown in lower heights than photogrammetry. Moreover, as lower height is above terrain than the overlap between subsequent LIDAR strips is also lower. This situation can also lead towards the negative value in extreme instances. This paper also describes the most effective way for flight planning during laser scanning of mountain terrain by comparison of two different technologies from operational and economical point of view.

Title of article: The Genesis and Metamorphoses of Risk
Authors: Tomáš Klieštik, Miloš Birtusz
Abstract: Each business activity and also an individual person face risk every day. But what is risk? People have different attitudes to risk. Natural survival instincts make some people use all possible means to avoid injury or loss. These decisions are not decisions but more of inner instincts of survival. If we move from an individual to an organization, standards and rules become more complex and more formal. When activities become more complex, instinctive and institutional patterns of behaviour forming the basis of personal risk management become inadequate and decisions become more complicated. The theory of risk has been a subject dealt with in many available books by domestic and foreign authors and risk management as such has been a subject of detail research. We can even claim it constitutes an independent part of the theory of economy.
