Abstract: The paper presents a new algorithm for reflection symmetry detection, which is specialized to detect maximal symmetric patterns in an Earth observation (EO) dataset. First, we stress the particularities that make symmetry detection in EO data different from detection in other geometric sets. The EO data acquisition cannot provide exact pairs of symmetric elements and, therefore, the approximate symmetry must be addressed, which is accomplished by voxelization. Besides this, the EO data symmetric patterns in the top view usually contain the most useful information for further processing and, thus, it suffices to detect symmetries with vertical symmetry planes. The algorithm first extracts the so-called interesting voxels and then finds symmetric pairs of line segments, separately for each horizontal voxel slice. The results with the same symmetry plane are then merged, first in individual slices and then through all the slices. The detected maximal symmetric patterns represent the so-called partial symmetries, which can be further processed to identify global and local symmetries. LiDAR datasets of six urban and natural attractions in Slovenia of different scales and in different voxel resolutions were analyzed in this paper, demonstrating high detection speed and quality of solutions.

Abstract: The fourteenth international biennial conference Criminal Justice and Security in Central and Eastern Europe, organised by the Faculty of Criminal Justice and Security, University of Maribor (UM FCJS) on 12–14 September 2023, is subtitled The United Nations Sustainable Development Goals – Rural and Urban Safety and Security Perspectives and addresses current challenges related to the UN SDGs and the provision of security in local communities. Topics of the conference are related to a research project of the UM FCJS on local safety and security – rural and urban perspectives (2019-20124) based on the UN SDGs that aim at the development of democratic societies trying to achieve seventeen ambitious goals globally. The conference is also a milestone that signifies thirteen years of membership of the UM FCJS in the United Nation’s Academic Impact Network (UNAI). The book of abstracts includes more than sixty abstracts of papers presented at the conference. The main topics of this year’s conference are rural criminology, criminal justice, policing, covid-19, crime, criminality, crime prevention, perception of crime, crime analysis, safety, security, community (oriented) policing, victimology and penology. Thanks for this great academic event go to the programme and organising committees, authors, participants and conference supporters nationally and internationally.

Abstract: The scientific monograph on current topics of tourism development, which is intertwined with the field of health, well-being, and the role of local authorities in planning, implementing, and evaluating policies and practices related to public health issues, offers the reader a systematic theoretical review of scientific literature, as well as case studies of the topics discussed. The content is presented by numerous researchers and experts who are active in Slovenia or other countries of the former Yugoslavia. The topics address current issues in the development of tourism science. The content is multidisciplinary and interconnects various views and concepts that provide an insight into the profession for the needs of further development of the sector.
Keywords: tourism, development, thematic tourism, sport tourism, well-being, public health, the role of local authorities

Abstract: The strategy of the University of Maribor pursues an inclusive, innovative and integrated higher education area that will train active, critically-thinking and responsible citizens, guarantee the quality of education and research, academic integrity, and cultivate concern for sustainable development of society. It stresses the importance of the freedom of research and institutional autonomy, development of lifelong learning, digitalisation and green infrastructure. It follows the orientations of the Rome Ministerial Communiqué of 2020 on the development of higher education in Europe, the Magna Charta Universitatum 2020 principles and the national strategic documents on higher education.
Keywords: organization and connectivity, education, scientific research and art, stimulating working environment, students, internationalisation, development through quality system, involvement in local environment, spatial development, IT support

Abstract: Purpose: This paper deals with the legal regulation of Estonia’s public order from the aspect of local governments. The purpose of the article is to analyse relevant Estonian legislation to help identify problems and make suggestions for improvement. Proposals are intended for the institutions involved in developing legislation in Estonia. Local governments in the country act according to the Constitution of the Republic of Estonia (1992), but still retain enough legal autonomy to decide on local affairs independently of the state government. Methods: The paper is based on an analysis of national legislation. In the legal research, the author pays attention to written sources of law, e.g. the Constitution of the Republic of Estonia (1992), and subsequent legal acts regulating public order. Findings: The main task of local government is to provide public services and improve the quality of the living environment. In Estonia, the principal provider of internal security is the Police and Border Guard Board. It is the responsibility of local government to assist the national structures in fulfilling their duties. On the other hand, the municipalities are required to ensure public order within their territories. The legal power given by parliament to local governments to carry out such activities is insufficient to ensure the law is enforced. Practical Implications: The findings in this paper highlight areas in which the legal regulation could be improved. Originality/Value: Although the legal basis for Estonian municipalities’ operations has been studied carefully, it is necessary to examine issues concerning the links between local governments and public order in detail. The continually changing legislation makes the situation complex to handle. It also provides an opportunity for international comparative analysis with other European Union member states.
