Lepenski Vir is an archaeological site of extraordinary international significance; an area where exceptional culture and specific art, which took place within organized social and religious life, emerged as unique in Central and South-Eastern Europe (6800-5400 BC, according to the date C14). The methods and complexity of the architecture of these buildings, their sustainability and energy efficiency, as well as the treatment of the associated monumental sculptures, clearly define the stages of settlement over a period of at least two thousand years. Today, it is even possible to say that people in those ancient times were even more instructed in the issues of nature and her whimsicality than we are today. Today, the site is in a natural reserve in an extremely picturesque landscape. During the archaeological excavations of the 1960s, seven prehistoric settlements were unearthed, one after the other. These settlements contain the remains of 67 apparently planned dwellings, fireplaces, tools, instruments, and jewellery. The settlements also contain altars and sculptures, carved out of round limestone pieces that are of artistic and aesthetic, as well as ritual and symbolic importance. The paper elaborates on the harmony of architectural style and natural surroundings that has been considered since the earliest times. Its aim is to analyse Lepenski Vir, one of the most significant archaeological sites in the world, i.e., the technique and the conditions under which it was created. However, as the reality of the subject is quite elusive in today's time, this paper seeks to show the value of the principles on which ancient architecture rests, primarily using natural materials and specific simple forms in design and construction. The reason for this is the inextricable link between man and nature at all times, the very essence of their interconnectedness, as well as the creation of a healthy, aesthetically valuable, and quality living space. Based on these analyses, one specific conceptual solution will be attached, i.e., the proposal of a contemporary interpretation of the ancient Lepenski Vir settlement and houses that can meet the needs of modern man and age, where millennia-old tradition is implemented in contemporary Serbian architecture.

The main goal of soft computing technologies (fuzzy logic, neural networks, fuzzy rule-based systems, data mining techniques…) is to find and describe the structural patterns in the data in order to try to explain connections between data and on their basis create predictive or descriptive models. Integration of these technologies in sensor nodes seems to be a good idea because it can significantly lead to network performances improvements, above all to reduce the energy consumption and enhance the lifetime of the network. The purpose of this paper is to analyze different algorithms in the case of fire confidence determination in order to see which of the methods and parameter values work best for the given problem. Hence, an analysis between different classification algorithms in a case of nominal and numerical d

Personal interests carry a great potential and are usually a drive to act. Therefore they usually point towards the activity of an individual in his interest area. An insight into the position of the interest in sports and recreation among other interests can be obtained by inspecting the interests of 7th grade elementary school students from Sremska Mitrovica and Jagodina. The sample consisted of 736 7th grade elementary school students of both genders. A non-experimental study of the students’ interests was done using a questionnaire that consisted of 5 interest indicators: job preference, self-estimation of affinity, use of free time, direct self-estimation of interests and reaction to key words-stimuli. Each indicator had 30 items that asses 30 interests. A t test was used to inspect the level of interest in sports and recreation. Also, factor analysis was done for each indicator separately. The reason for this approach is that there is no real confirmation that these 5 indicators are well suited for assessing the interests of young persons in the time we live in. Students’ interest in sports and recreation is about 4 on the scale of 1 to 5, on each of the indicators. The data shows that the interest of 7th grade elementary school students in sports and recreation is closely linked to interest in military, these two interests belong to the same factor regardless of the way the interests are assessed, that is, they belong to the same factor on each of the 5 indicators. The interest in adventure belongs to the same factor as the interest in sports and recreation on 4 out of 5 indicators, and interest in humor, interest in travel and hedonistic interest on 3 out of 5 indicators. These results might indicate that the motives for engaging in sports and recreation are unstable, because this composition of relatedness of the interests can be interpreted as the factor of fun. If that is so, these findings alert to the importance of building a system of human values in which the physical education, taken in a broader sense, will have a significant place. A high level of students’ interest in sports and education is a good starting point for reflecting upon the practice in the system of physical education and the system of sports of young persons. However, we must bear in mind the structure of interests. Professionals in the physical education area are obligated by the interests’ value orientation to positively influence the youth.

Evaluation of students in PE class is a complex process that requires detailed planning and grading is an important part of it. This is why the grading criteria need to be clearly defined and a constant approach needs to be developed for their applica¬tion. This paper describes a way to grade the motoric skills of students. Evaluation was conducted on a sample of seventh-grade students of both sexes N=51, male n=27, and female n=24. The tests encompassed tossing a medicine ball, long jump from standing, 30 meter dash, trying to stay in the knuckle, and bouncing a ball off the wall for 15 seconds. The results in the disciplines 30 meter dash, long jump from standing and bouncing a ball off the wall for 15 seconds are laid out here in accordance with the standard deviation of the results for the entire test group (all three seventh-grade classes) while the disciplines tossing a medicine ball and trying to stay in the knuckle were conducted using the formula that encompassed body mass and a corresponding coefficient. The results indicate students’ expected capabilities in motoric skills tests. Disciplines such as 30 meter dash, long jump from standing and bouncing a ball off the wall for 15 seconds can be evaluated in the absolute sense when compared to the appropriate results achieved by other students within the same age group but the disciplines such as tossing a medicine ball and trying to stay in the knuckle require additional measurements. Coefficients introduced into the formulae that are used to compute the results are derived from the standard motoric skills and morphological characteristics tests for the students of both sexes. The evaluation of students’ motoric skills must take into consideration their individual characteristics and model characteristics of the corresponding population that are determined from time to time. This kind of approach adds to a more objective view of students’ motoric skills.

Children aged 4 and 5 have great motor potential. Testing certain motor skills and measuring morphological characteristics are important steps in examining sport development of children. The subject of this paper is assessing motor skills and measuring morphological characteristics of students of sport school Sportomanija in Belgrade. The sample was made up of 16 male examinees aged 4 and 5. The battery of motor tests was composed of the following : deep reach (standing position), standing long jump, 20 metres running, 4x5 metres running, lying into sitting position in 20 seconds. Statistical analysis of results meant correlating results of motor tests and anthropometric measurment. The results show a statistically relevant negative correlation between body mass index (BMI) and long jump results (r=-0,55, p

Being a significant area of human activity, sport has multiple functions. One of the more important functions of sport, especially top sport, is the inventive heuristic function. Creative work, being a process of creating new values, represents a significant possibility for advancement of sport. This paper aims at pointing at the various dimensions of human creative work, at the creative work which can be seen in sport (in a narrow sense) and at the scientific and practical areas which borderline sport. The method of theoretical analysis of different approaches to the phenomenon of creative work , both in general and in sport, was applied in this paper. This area can be systematized according to various criterion : the level of creative work, different fields where it appears, the subjects of creative work - creators etc. Case analysis shows that the field of creative work in sport is widening and deepening constantly. There are different levels of creativity not only in the system of training and competition, but in a wider social context of sport as well. As a process of human spirit and mind the creative work belongs not just to athletes and coaches, but also to all the people and social groups who's creative power manifests itself in sport. The classification of creative work in sport according to various criterion allows for heuristic function of sport to be explained comprehensively and to create an image how do the sparks of human spirit improve the micro cosmos of sport. A thorough classification of creative work in sport allows for a detailed analysis of all the elements of creative work and each of it’s area in sport. In this way the progress in sport , as a consequence of innovations in both competitions and athletes’ training and of everything that goes with those activities, can be guided into the needed direction more easily as well as studied and applied.

This article explores new dimensions of security in the context of postmodernity. The article highlights the influence of postmodernism and postmodernity on security culture and presents necessary measures to mitigate the risks associated with this paradigm. In a society characterized by plurality, relativism, and diversity, security culture must evolve to address new digital challenges. It presents how the concept of the relativization of truth from the perspective of postmodernism can affect the approach to security, highlighting both benefits and challenges. It also examines the impact of globalization and digitization on security, highlighting the need for international cooperation and interdisciplinary strategies. The article emphasizes that promoting digital education, raising awareness, developing collaboration, and implementing technology are crucial in building an adaptable and effective security culture in the face of the challenges of postmodernity.

The accelerated development of media technologies in the last decade has not received an adequate response from society as a whole regarding the implementation of a set of ethical norms and legal regulations. This suggests that the environment in which information is created and disseminated has become distorted, allowing for the proliferation of fake news and the multiplication of populist messages.This article highlights how populist ideologies, amplified by the cultural paradigm of posttruth and fact-free societies, impact security culture by altering the Overton Window. This manipulation of public opinion changes the priorities and directions of security policy. Simultaneously, the article proposes a series of measures to counter fake news and the manipulation of public opinion through populist messages
