cultural and historical heritage, documenting the cultural and historical heritage, laser scanning The primary objective of this paper is to present the characteristics of laser scanning technology in the documentation of cultural and historical heritage objects of complex shapes. Generally speaking, the digital recording of monuments is a complex process that depends highly on the nature of subject as well as on applied surveying methods and processing. The paper describes the geometric documentation of the monument ‘Wounded Lion’, which begins with the collection of data, followed with processing, and concludes with the presentation of the final results. At present, 3D models are frequently used for the dissemination of information about cultural and historical heritage objects, e.g., via web pages in the form of VRML models. However, the creation, publication, and interaction of high-resolution 3D textured models remain rather challenging and difficult tasks. Such models, with a certain level of accuracy, are clearly invaluable tools for applications involving the restoration, maintenance, and monitoring of monuments. The goal of this paper is to explore the process of creating detailed and accurate (to the greatest degree possible) 3D models.

The aim of the study was to determine the presence of risk factors for developing hypertension in the University of Belgrade student population whose faculties do not provide the opportunity to learn about these factors. A cross-sectional study was conducted during November and December 2015 at the Faculty of Mechanical Engineering, the Faculty of Electric Engineering and the Faculty of Law. The respondents filled in a questionnaire, which was approved by the Ethics Committee for bio-medical research from the Faculty of Pharmacy. The study included 487 students. 56.7% were male students. Most of the respondents studied Law (210), followed by Mechanical Engineering (168) and Electrical Engineering (109). 75.8% of respondents consumed salty snacks, while 34.5% of them changed their habits of consuming snacks during the examination period. Fish was consumed less than once a week by 39.8% of the respondents, whereas 19.9% of them consumed candies every day. 63.9% consumed fast food. Energy drinks were not consumed by the majority (52.2%), while 22.4% only consumed them before an exam. The research results indicated the presence of reversible risk factors in the examined student population. In order to prevent the development of hypertension in the elderly population and reduce the number of risk factors present, it is necessary to develop educational programs for proper diet and adequate intake of food groups.
