Tourist destinations around the world are trying to cope with the needs of visitors, which are very susceptible to change. Nowadays, tourists are becoming more sophisticated and knowledgeable; their needs for extensive and diverse experiences increasing. As opposed to the destinations whose tourism development depends on the natural resources that are difficult to influence and whose business is susceptible to the negative impacts of seasonality, destinations of city and cultural tourism have more space to design their offers and contents that can satisfy the needs of travelers of the modern age. Content that can make a destination unique and well known, is the cultural heritage created in the Art Nouveau style. The Vienna secession architectural masterpieces can represent major tourist attractions in some destinations. For example, many attractive tourist cities such as Aveiro, Barcelona, Prague and Hamburg tourists visit just in order to feel and experience these works of art. For this reason, it is very important to point out Art Nouveau as an essential part of the cultural heritage of the destination and enable informing and introducing tourists with this valuable tourism potential. The initial hypothesis of this paper is that Aveiro has authentic cultural heritage in the Art Nouveau style that enriches the tourist offer of the city and that attracts a certain segment of the tourism market. The aim of the paper is to examine the participation and influence of Art Nouveau heritage in the tourism industry of Aveiro.

This paper describes full lab-scale investigation of Middle-Bosnia coals launched to support selection an appropriate combustion technology and to support opti- mization of the boiler design. Tested mix of Middle-Bosnia brown coals is pro- jected coal for new co-generation power plant Kakanj Unit 8 (300-450 MWe), EP B&H electricity utility. The basic coal blend consisting of the coals Ka- kanj:Breza:Zenica at approximate mass ratio of 70:20:10 is low grade brown coal with very high percentage of ash - over 40%. Testing that coal in circulated fluidized bed combustion technique, performed at Ruhr-University Bohum and Doosan Lentjes GmbH, has shown its inconveniency for fluidized bed combustion technology, primarily due to the agglomeration problems. Tests of these coals in PFC (pulverized fuel combustion) technology have been performed in referent laboratory at Faculty of Mechanical Engineering of Sarajevo University, on a lab-scale PFC furnace, to provide reliable data for further analysis. The PFC tests results are fitted well with previously obtained results of the burning similar Bosnian coal blends in the PFC dry bottom furnace technique. Combination of the coals shares, the process temperature and the air combustion distribution for the lowest NOx and SO2 emissions was found in this work, provided that combus- tion efficiency and CO emissions are within very strict criteria, considering spe- cific settlement of lab-scale furnace. Sustainability assessment based on calcula- tion economic and environmental indicators, in combination with Low Cost Planning method, is used for optimization the power plant design. The results of the full lab-scale investigation will help in selection optimal Boiler design, to achieve sustainable energy system with high-efficient and clean combustion tech- nology applied for given coals.

This paper presents a strategy and action plan was implemented in the Federation of Bosnia and Herzegovina within the Ministry of Interior within 5 years. Given are the steps to achieve the strategic objectives.

Introduction: Elderly persons have higher risk for falls, compared to younger population. Although no single risk factor causes all falls, a great deal of risk factors to which an individual is exposed, i.e. osteoporosis, lack of physical activity, impaired vision, usage of drugs, living settings etc, can be treated. Objective: To investigate the risk for falls in elderly patients treated in Family medicine teaching center (ECPM), Primary Health Care Center Banja Luka. Method: This prospective study was conducted in June 2012. The study included 150 patients aged 65 years and older. Patients were chosen randomly. In study were included patients who have visited their family doctors on every of Mondays in June 2012. The Tinetti Gait and Balance Instrument was used to asses the risk for falls. Patients were examined to asses gait and balance according to Tinetti questionnaire, and supplementary questionnaire was created to record data about age, sex, chronic diseases and drugs that patients take. Results: The study included 91 (60.7%) female and 59 (39.3%) male patients. The average age of patients was 74.71 years. 77 (51.3%) were aged 65 to 75 years and 73 (48.7%) were more than 75 years old. Results of Tinetti Gait and Balance Instrument showed that the risk for falls was high in 55 (36.7%), moderate in 31 (20.7%) and low in 64 (42.7%) patients. Conclusion: Approximately, one third of investigated patients had high risk for falls, what indicates that family doctors should be more involved in fall prevention in elderly and in constant educating of older adults and their families.
