Also the 4th Dimension of the Town - Its Underground Structures - Has Its Risks
Karel Klouda, Stanislav Bradka
Communications - Scientific Letters of the University of Zilina 2008, 10(1):5-9 | DOI: 10.26552/com.C.2008.1.5-9 
The article is devoted to risk assessment of underground structures from the point of view of their existence, operation and human failure (of users and/or operators). Two likely instances of their abuse for disseminating poisonous substances in an urban agglomeration are described. Both possibilities have been scrutinized using either physical simulation or an in-situ experiment. The distribution of agent depending on chosen parameters (agent's imitation, meteorological conditions, etc.) was verified on Prague's Old Town Square model in an aerodynamic tunnel. The in situ experiment with surrogates was performed at underground subway changing station....

Communications - Scientific Letters of the University of Zilina 2008, 10(1):10-15 | DOI: 10.26552/com.C.2008.1.10-15
Major accidents in storage tank farms can result in severe threats for emergency responders, neighbouring population and the environment as it was observed in the case of Buncefield (2005). The numerical modelling of dangerous phenomena is an important tool to support emergency planning for such complicated events. For this purpose, the case study in crude oil tank farm involving selection of reference accident scenario, CFD simulation of tank fire and prediction of delay to boilover was performed. The results were used to review the existing emergency plans and to enhance the tactical preparedness of emergency responders.

Numerous and wide-ranging initiatives are being pursued all over the world today to help pass on a sound natural environment to future generations. Automotive production is one of Slovakian leading industries. Because of urgent priority on protecting the environment, it is inevitable for manufacturers to be engaged in ongoing efforts to develop more environmentally friendly automobiles and a more viable infrastructure for them - one in which provisions for environmental protection, including recycling, constitute an essential part. The Life Cycle Assessment (LCA) is atool for the systematic evaluation of the environmental aspects of aproduct or service...
Risk Analysis - General Approach
Pavel Danihelka, Pavel Polednak
Communications - Scientific Letters of the University of Zilina 2008, 10(1):20-23 | DOI: 10.26552/com.C.2008.1.20-23
The article deals with a general theory of risk analysis and corresponding risk management and provides the overview of the systematic method of risk analysis based on the MADS-MOSAR concept. Risk is represented as aflux of danger and typology of sources of danger, flux mechanism and potential targets are described. Quantification of risk is done as acombination of uncertainty and impact of an unwanted event and risk management is based on safety barriers introduction to overall process described by combination of FTA and ETA, so called "bow-tie diagram".
Modelling in Development of Safety-Related Communication Systems
Karol Rastocny, Maria Franekova
Communications - Scientific Letters of the University of Zilina 2008, 10(1):24-30 | DOI: 10.26552/com.C.2008.1.24-30
The aim of the paper is the use of modelling within development of safety-related communication systems presented in the areas where guaranty of asafety integrity level is required. The basic principles and standards used in the process of safety evaluation in closed transmission systems are summarised in the paper. Dangerous states of the system are mainly caused by systematic failures within aspecification of the system, electromagnetic disturbance and random failures the HW effects. The main part of the paper describes the safety analysis process on the example of the end to end closed transmission system with the use of the fault tree and Markov's chain.

Vladimir Klaban
Communications - Scientific Letters of the University of Zilina 2008, 10(1):31-34 | DOI: 10.26552/com.C.2008.1.31-34
The basis of safety engineering is acceptance, introduction and maintenance of measures aimed at safety in various, mainly technical areas of human activities. Safety is a state during which there is an admissible probability of occurrence of damage to protected interests. Insolvency is a state of incapacity to pay. In the contribution, the specified definitions are developed, their mutual relations are shown and their connection with sustainable development theory and practice is emphasised.

Nowadays in the territory of Slovak republic, the property protection and security systems design lies in realization of requirements following from security requirements specifying details of tangible property protection (Law, Risk Analyze, Internal regulations of the company). In this article, three basic approaches to secure physical protection of property will be introduced. There is directive-oriented, variant-oriented and variable way of physical protection. For the most effective way of protection we can consider the variable way of protection, which allows due to its flexibility designing of the system in such a way, that it best suits requirements,...

Critical Infrastructure Risks
Michail Senovsky, Pavel Senovsky
Communications - Scientific Letters of the University of Zilina 2008, 10(1):54-59 | DOI: 10.26552/com.C.2008.1.54-59
Critical infrastructure can be taken as aphenomenon of recent time. Not only theory but also practice has shown that solving problems of the protection of critical infrastructure, especially ensuring its functionality, is a necessary precondition for the operation of public authorities, services, the viability of aregion, area or country. The first step to protect the critical infrastructure must be the identification of risks endangering the security of single systems or elements. The contribution deals with the problems of searching for and denoting these risks and by looking for their interrelations.

Rail transport plays akey role in transport services within adomestic and international scope. In the scope of social and economic changes and the dynamically developing transport sector, it is the task of railways to analyse and programmatically prepare its management. In the context of European and national traffic policy the strategy of Railways of the Slovak Republic (ZSR - Zeleznice Slovenskej republiky) identifies the need for successful technological and company development in the coming decades. This short paper of ZSR strategy contributes to better knowledge and apositive presentation of the direction of ZSR towards bodies of state administration...
