Title of article: The trend of a number of internet connections in Slovakia and selected European countries
Author: Matej Pechota, Mária Matúšková
Abstract: Nowadays we live in a time, when the number of internet connections are growing as users start sending information mostly via the internet. This article consists of statistics and information about the internet connections in Slovakia and through statistical methods we will calculate if the trend grows or rises in every district of Slovakia. The trend shows us, how important it is to adapt from postal services to new trends and take care about users who want to use postal services in this new way and to demonstrate that the number of internet connections are growing in every country. In this article we will compare statistical data between Slovakia and selected European countries. For more specific results, we should calculate the trend per citizen. The reason is, that we should compare countries where much more citizens live, than in Slovakia. This article focuses on the situation in the Slovak market. It could help to demonstrate how electronic communication and postal services could cooperate.

Authors: Justyna Reut, Jacek Caban, Bożena Widzicka
Abstract: Each industry is characterized that without human factor will not be able to function. This also applies to aviation, which focuses mainly on human labour. This sense of security what provides staff workers, on what the shoulders are the duty of care not to create a hazard before, during and after the flight. On the civil and military airports they employ staff not only flying but also ground handling. These include: auditors, managers flights, technicians, ground handling runway and apron, cargo department employees, firefighters and other emergency services, personnel service to passengers in the terminals, customs, security, and even people like hawkers, law enforcement officers, managers and managers of the various sectors. Each of these professions is responsible for a different aspect of the airport, and is necessary for the proper conduct of flight operations and passenger services and ensuring security. In the largest airports with lots of terminals with dense air traffic performance characteristics of employed people, the variety of tasks, and thus the level of complexity of the operation resemble a small town. In order for it to function efficiently is all you need is a good organization, through which cooperation between all departments of work is smooth and provides quick action in dangerous situations.

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.
