The possibility of involving the general public to DRM implementation is, currently, a frequently discussed topic. In particular, population preparedness for the involvement of the public is questionable and, therefore, the understanding of the conditions that facilitate public preparedness for disasters is decisive. This article presents the results of research that investigates the factors affecting (1) the objective preparedness of the population, as well as (2) the subjective perception of our preparedness for disasters. The statistical analysis discovered that both sides of the public’s preparedness depended especially on their experience with disasters, the awareness of the possible risks and appropriate procedures to solve situations, and the economic potential of the households. The results empha...

The article sets out the theoretical and practical aspects of the lean enterprise. The concept of Lean Production and its main goals are considered. The classical characteristic of the Lean Production concept to the main types of losses is highlighted. The concept of Lean Logistics is proposed as a Lean Production tool. The content of the concept of Lean Logistics is disclosed. The main reasons leading to the occurrence of logistic losses are considered. The analysis of basic tools and methods that can be applied in Lean Logistics. The possibilities of obtaining benefits from Lean Production tools, when applied in a logistics strategy, are considered. Lean Production methods used in logistics are proposed. The economic benefits of implementing Lean Logistics tools are presented. Recommendations for further research are provided.

Many cities in the world are already transforming their ways to be more efficient, greener and also safer. According to our studies, field of safety receives less focus in development strategies than other fields of smart development. However, to create a real Smart City, it is needed to understand the city as a complex environment, with their smart and safe concepts as interconnected parts. This paper deals with interconnected Smart City and Safe City concepts and it presents systems, that are common to both, equal concepts. Systems are divided into layers and features, needed in every system, are further summarized. Number of studied and compared works, dealing with respective systems from various points of view, our own experiences and communication with executives, responsible for smart development of Tampere city resulted in definitions, describing bo...

Pascal compared in his days human knowledge to a sphere, which escalates its surface area with the development of knowledge, thus ever extending the limit with the unknown, which calls for a solution of further, typically serious problems. The third millennium opens before man unexpected possibilities in the field of science and technology and new revolutionary discoveries. However, on the other hand, the human being is facing complex problems of the protection against effects of natural disasters, growing global terrorism, social-economic consequences of financial crises, extensive accounting frauds and, last but not least, attenuation of the natural self-regulation of the environment. The history of the world is the history of disasters occurring to different extents, from earthquakes, floods, global wars, through terrorist attacks and accidents of local importance. Consequences of disasters are frequently considered based on human victims and "visible" material damages. However, new phenomena of the time being should not be forgotten, such as computer viruses, financial crises, large accounting frauds, etc. There are only minimum human victims and direct material damages in these cases, but the events considerably affect the economy in particular countries and their secondary catastrophic consequences exceed limits of continents. Disasters became a part of our life. They are perceived through the mediation of TV screens, print and in certain cases also through personal experience. After 2000, consequences of disasters exert increasing trends. In 2007, the securing company SwissRe recorded total of 335 disasters, where the large portion-42.4%, corresponded to natural ones. Unfortunately, none of the most destructive natural disasters was reflected in the insured damages. Five disasters, most expensive for insurance companies and securing companies, were recorded in Europe and United States.

In the first part of this paper we point out the short description of the phases and the possible use of GIS within these phases and in simulations within crisis management. In the second part we introduce the GIS in the Slovak Republic with focuses on use in crisis management. The third part is giving possibilities of the interconnections among simulation technologies and GIS within crisis management with a focus on the newly built Laboratory of Modelling and Simulation of Crisis Phenomena in Transport and in different environments. Within conclusions we would like to point out the possibilities for further discussions and directions within this interesting and important topic.

Also an experiment on a real technological device can be used as the basic scientific method of research when assessing and evaluating risks in the industrial processes. However, experimenting with technological equipment which uses hazardous substances is very risky and can be the source of an accident, or disaster, e.g. the disaster at the nuclear power plant in Chernobyl in 1986.
