Summary

The concept of resilience is probably one of the best-known new international concepts, which have gained attention since the economic crisis in 2008. Since then, this global challenge has redirected general focus at all tiers from "faith" in unstoppable progress to more desirable stabilisation and preparedness. Being the major places of globalism, cities across the World have suffered from the crisis. Therefore, they have profoundly embraced the postulates of resilience, transforming them with "urban" footprint-urban resilience. The creation of this significant concept has been in the agenda of many international organisations. However, the concept of urban resilience is still a novelty, with accompanying implementation problems. This is a very important issue in the field of urban design, a part of urbanism very much connected to concrete functioning in situ. This "implementability" of the concept of resilience in urban design is an important issue for Serbia. As a post-socialist country, it has witnessed various problems and general inconsistency. With a strong motive to cope with them, local authorities and institutions often try to directly implement foreign-arisen concepts and knowledge, without any local adaptation. The results of these forceful acts are usually questionable. Therefore, the aim of this paper is to understand how the principles of resilient urban design are tailored and how they are important for Serbian cities. Hence, general urban plans as the main development documents in Serbian cities are researched through the lenses of these principles, with expectations to check if they are ready to make urban design in relevant cities more resistant. The final contribution of the paper is foreseen in the form of guidelines to enforce urban resilience at local level.

: Security and protection demands in tourism industry are very high due to the vulnerability of its infrastructure in light of security challenges and threats. Actual threats appear in the form of endangering the values that compose a train of products and services in tourism – from the moment of buying/selling a package tour, transfer of passengers and luggage to their destination, to stay in hotels and meeting different needs of tourists. This work addresses the criminal, terrorist, and economic threats to hotels. The effects of these and other threats may endanger the foreign investments in tourism industry and the arrival of foreign tourists who, as the newest polls show, prioritize security factor in their selection of tourist destination. The hotel security issue is addressed in light of its preference when selecting tourism supply and services, which is an important indication of competitive advantage.

In recent years, there has been a great development of methodologies, procedures and software tools for quantitative assessment of reliability, efficiency and effectiveness of physical protection systems. Absence of some important input values, as well as missing method to obtain them, is still the most serious problem. This paper is focused on analysis of possibilities how to obtain delay time values in the case of cylinder pin tumbler locks using non-destructive methods of breaking. In the introduction of the article, a proposal of the methodology for testing the mechanical resistance of cylinder pin tumbler locks is elaborated. Consequently, the focus is set on analysis of results obtained during the pilot tests in order to verify the correctness of the proposed methodology. With the tests, it is possible to assess the resulting resistance of cylinder pin tumbler locks also in terms of classification into resistance classes. The pilot testing needs to be implemented mainly due to the lack of a technical standard that processes the issue within the established methodology.
