Fulfilling the requirements for export of metal industry products from Serbia and Bosnia and Herzegovina cross-border area to EU market

Izvoz na tržište Evropske unije podrazumeva slobodan protok ljudi, proizvoda i usluga kao i širok spektar mogućnosti za preduzeća, ali takodje uključuje i niz poteškoća i zahteva koji se u tom cilju moraju ispuniti. Kako je izvoz u EU izazov za preduzeća metalske industrije u Srbiji i Bosni i Hercegovini, u ovo istraživanje je uključeno 20 malih i srednjih preduzeća iz prekogranične oblasti - Sarajevskog i Zlatiborskog okruga, tradicionalno orijentisanih ka izvozu, kako bi se poboljšale aktivnosti vezane za ispunjenje zahteva za izvoz proizvoda metalske industrije iz datih oblasti. Analizirane su statistički značajne razlike uticajnih parametara na ispunjenje zahteva za izvoz proizvoda metalske industrije u prekograničnoj oblasti Srbije i BIH na tržište EU, finansijsko stanje i ulaganje u obuku zaposlenih, primena Direktiva novog pristupa, posedovanje standarda sistema menadžmenta i dr. Rezultati analiza su pokazali da najveći problem u obe regije predstavljaju finansijska sredstva za ispunjenje formalnih zahteva, a izvozna barijera sa najvišom vrednošću u obe regije je nedostatak državne pomoći i podsticaja. Shodno sprovedenom emprijskom istraživanju u radu su date preporuke preduzećima metalske industrije obe regije. Istraživanje ispunjenja zahteva za izvoz proizvoda metalske industrije na tržište EU u prekograničnoj oblasti Srbije i BIH pruža mogućnost da se preduzeća iz datih regija povežu i podstaknu da, kroz primenu i razmenu savremenih znanja i veština, evropskih procedura i standarda, podizanje tehnološkog nivoa i zajedničke promotivne nastupe, postanu konkurentnija.Exporting to European Union market includes free exchange of people, goods and services as well as wide range of opportunities for companies, but also includes many difficulties and requirements which need to be fulfilled. As exporting is a difficult challenge for metal industry companies in Serbia and Bosnia and Herzegovina, this study included 20 small and medium sized companies from cross-border area - Zlatibor and Sarajevo districts, which have traditionally been export oriented, in order to improve activities regarding fulfilling the requirements for export of metal industry products from given regions. Analyses were conducted on statistically significant differences between influential parameters on fulfilling the requirements for export of metal industry products in cross border area of Serbia and BIH to EU market, financial standings and investment in the employee development, implementation of New Approach directives, implementation of management system standards and other. It was found that the largest issue in both Sarajevo and Zlatibor district are financial resources for fulfilling the requirements, while most influential obstacle is lack of government support and incentives. Recommendations are given to metal industry companies in both districts, based on the conducted empirical research. The research on fulfilling requirements for export of metal industry products to the EU market in the cross-border area of Serbia and BIH gives opportunity for companies in those areas to be connected and motivated to become more competitive, by using and exchanging modern knowledge and skills, European procedures and standards, raising the technological level and mutual promotional appearances

ANALYSIS OF TOURIST MOTIFS IN THE FUNCTION OF DEVELOPMENT OF CULTURAL TOURISM IN THE SETTLEMENTS SURROUNDED BY PROTECTED NATURAL RESOURCES

The paper deals with the presence of anthropogenic tourist motifs in the area of the Special Nature Reserve “Carska bara” in the north of Serbia with the following rural settlements taken into consideration: Belo Blato, Ečka, Knićanin, Lukino Selo, Perlez and Stajićevo. The presence of cultural heritage from a group of archaeological sites, works of monumental and artistic features, spatial cultural and historical units, famous places and memorials, folklore heritage, religion and beliefs, language and manifestation values has been recorded in the studied area. The area is well connected with the city centers of this part of Serbia and for the current level of tourism development, it has a satisfactory number of accommodation capacities. After analyzing literature and local cultural offer, it is concluded that for the purpose of attracting more tourists, cultural, that is anthropogenic tourist motifs must be united in the offer with the natural phenomenon Carska bara and its near environment. Together, they can lead to the development of an increasingly popular type of cultural tourism — creative tourism, enchanting tourists the life of the local population, their culture and customs

Risk Based Approach to Integrity Assessment of a Large Spherical Pressure Vessel

The risk based approach has been applied, in its simplest form, i.e. by using the risk matrix to illustrate how the water proof test can shift risk from high to very high level in the case of large spherical pressure vessel (ammonia storage tank). Having in mind the basic definition of risk, being the product of the probability and consequence, and fixing the consequence at the highest level, only probability of unfavourable event (leakage and/or failure) has been evaluated. Toward this end, the failure assessment diagram (FAD) has been used here as another simple engineering tool to estimate probability of the failure, as the function of the position of the operating point, i.e. defming probability as the ratio between the distance of the operating point from the zero point, and the appropriate distance between the point on the limiting curve and zero point. This simple engineering tool to assess structural integrity showed clearly that water proof test is not always recommended, because it disregards possible stable growth of cracks, which might reach critical size for unstable growth, i.e. it does not prove that failure will not happen in future under the same conditions.

Bosnia and Herzegovina's metalworking industry companies barriers to export to EU market

Export of products and services on EU market can bring great benefits, but also sets requirements to companies which are not easy to meet. Metal processing industry today is the main exporter in Bosnia and Herzegovina (BIH). However value of import significantly exceeds value of the export. Therefore, there is a need to increase export to EU market. The aim of this paper is an empirical examination of the export possibilities to EU market, conducted on a sample of 24 metal complex companies in BIH. Obtained results indicate that adequate marketing strategy is a minor influential factor for export to EU market. Also the research shows that a significant number of companies is not familiar with new approach directives, as well as with procedures for conformity assessment. Most of the surveyed companies have an opinion that there is not enough number of adequate laboratories and institutions for export assistance. Also, the lack of capital for export financing in the companies as export barrier is significant. This topic should be further researched, as it is very important for companies' growth and development in BIH
