Science is built upon the continuous re-evaluation of evidence and empirical research driven by the desire for success and the fear of failure, while religion is based on the unconditional acceptance of original dogmatic traditions and fundamental principles of belief in God and eternal reward, coupled with the fear of divine punishment. Metaphysics, as the foundation of philosophical scientific thought, examines the nature of reality and existence, asking questions about what exists, why, in which time, space, and causality. Disaster risk management is an exact scientific discipline established on metaphysical examinations of causes and phenomena, along with mathematical models of prediction and consequence analysis. This paper explores the intriguing correlation between the logical relationships of metaphysical principles and disaster risk management. By delving into the philosophical realm of metaphysics, we analyze concepts such as uncertainty, causality, and the nature of reality. Drawing correlative connections, we examine the development of a logical matrix of cause and effect to better understand metaphysical principles that can timely alert decision-makers and improve their risk management strategies. Researching the interconnections of fundamental principles in the domains of risk, impact, and response capacity to crises offers a fresh perspective on addressing uncertainty and making informed decisions in complex situations. Conclusions will be defined using analytical-deductive and synthetic methods, comparing the relationship between metaphysics and applied science within the framework of the multimillennial challenges faced by humanity, from the time of Noah's flood to contemporary crises and approaches to resolving them. The paper will scientifically determine risks, impacts, and capacities for more effective responses to climatic and socio-political crises, challenging the professionalscientific community to proactively offer answers to the question: Can the acceptance and understanding of the 3D logical model of integrated application of metaphysics and risk management contribute to reducing the vulnerability of humankind?

The aim of this research was to systematize the available literature on the types and frequency of locomotor injuries in combat sports. The sample consisted of martial arts athletes (judo, karate, wrestling, boxing and taekwondo) of both sexes, aged 11-49 years. Survey questionnaires and medical reports were used as measuring instruments for assessing injuries in the research. The found data, presented numerically and in percentages, were used for further analysis. The results of this research show that the characteristics of injuries of the locomotor system in martial arts usually do not depend on the sex of the respondents. There is a higher frequency of injuries in competitions and lower in training (except for under-18s). The most common locations of injuries (head and neck, extremities and joints), types of injuries (contusions, bruises and fractures), and severity of injuries (mild, moderate, or severe) depended on the characteristics of martial arts (sports techniques, tactics, physical and mental fitness, etc.). By applying additional methods, by improving physical preparation that is adequately dosed with the improvement of technical and tactical elements, injuries to athletes could be prevented.

In this study, pyrophyllite was used for the first time in the composition of protective refractory coatings together with supplementary waste resources. The proposed refractory coatings are applicable for metallic and non-metallic structures, with the option of using them to protect machinery components in the chemical industry, metallurgy, and mining. Given that pyrophyllite has a low hardness, the goal was to improve the coating's resistance to cavitation erosion by adding 20 wt.% of hard refractory materials, i.e., crushed and micronized waste bricks based on mullite and corundum, respectively. Previous studies have demonstrated that protective coatings using a pyrophyllite filler have refractory qualities but insufficient resistance to cavitation erosion. As a result, the composition of refractory coatings, the preparation techniques, and the coating manufacturing process were altered. This study presents a simple method for combining conventional coatings made of refractory fillers (primary resource: pyrophyllite) with waste materials (mullite brick and corundum brick) used as reinforcement in protective refractory coatings for metal and non-metal structural elements that are highly resistant to cavitation erosion.

When solving real problems, and to make a quality decision, it is necessary to consider a great number of often complex parameters. For these reasons, the development of decision-making process modeling has seen significant growth in recent years, and multi-criteria optimization models have stood out among them as useful for solving complex and conflicting phenomena. Multi-criteria optimization models make it easier for decision-makers to find the optimal solution in situations where there are many different criteria, which can often conflict with each other. The choice of the appropriate method of exploitation of mineral deposits follows the consideration of the problem and the approach to further development, which is primarily the determination of the criteria that influence the choice of the optimal alternative.

Background: The Social Medicine and organization of health is science organized on the application of modern medicine principles in the health care of human groups and nations. The significant difference of social medicine from clinical disciplines is that the clinical medicine deals with problems of individuals and social medicine is devoted to community health and illness of the family, schools and work organizations from population groups to the overall people of one area or country. Public health refers to all organized measures (whether public or private) to prevent disease, promote health and prolong life among the population as a whole. Its activities aim to provide conditions in which people can be healthy and focus on entire populations, not on individual patients or diseases . Objective: The aims of this article are to show, based on the available literature: a) The development of Social medicine and Public health in the World and Bosnia and Herzegovina from the medieval period until the today. b) The most significant historical events that marked the development of Social medicine and Public health with emfesized most important scientists and discoverers with their achievements. Methods: The subject of this study was the development of Social medicine and Public health in the world and in the areas of Bosnia and Herzegovina from the uncient peertiod until today. In order to achieve the set goals, a) Retreival of professional and scientific literature; and b) Search of scientific databases and web pages on the Internet that offer adequate and relevant data and historical facts related to the subject of studies were carried out. Most of the facts are covered in previously published articles by the author of this paper and deposited in the PubMed and PubMed Central databases, as well as in books and monographs by the author of this text. Results and Discussion: Social medicine with the organization of the health care system is the scientific discipline, defined by the huge contents, clear goal and specific methodology. It has been presented flow of socio-medical development and implementation on worldwide during the past. Public health was defined by Charles-Edward A. Winslow, in 1920. as „the science and art of preventing disease, prolonging life, and promoting physical health and efficiency through organized community efforts for the sanitation of the environment, the control of community infections, the education of the individual in principles of personal hygiene, the organization of medical and nursing service for the early diagnosis and preventive treatment of disease, and the development of the social machinery which will ensure to every individual in the community a standard of living adequate for the maintenance of health“. The names of those who are deserved for socio-medical development and its insufficiency on the organization on health system and some specific parts of it. Social medicine, and Public health as sciences and profession had high level among other disciplines, but also as profession per se, specially at the international level. There is huge evidence of numerous projects, books, papers, recognized by indigenous and international audience. Conclusion: The most importants role in organizatiionn and realization of all kind of public health activities and measures at every healthcare protection levels has World Health Organization (WHO) with its brench offices at all continents and all countries in the world. The author described information flow how it was happened during the history of its development.

Here we will focus on two of the four indexed biomedical journals that were published in Sarajevo during wartime conditions in 1992-1995. The first is the Medical Archives, which was founded in 1947 and whose last editor until 1991 was the respected Academician Mirko Grujic, and whose last edited issue remained in storage (then the printing was done on Heidelberg machines and the text was typed using lead letters) and that unprinted issue – the number one volume in 1991 never even came out. Given that the contracts with the strongest index database MEDLINE included the Contract of the Assembly of doctors of Bosnia and Herzegovina (BiH), which at that time was the owner of the journal, and the pause in printing had already been going on for two years, Medline withdrew this journal as well. Numerous correspondences with the main responsible person Mr. Sheldon Kotzin, we received an unexpected consent from the Medline database to try to fill the gap with at least a few double-issues within 6 months, and Medline will meet us and reactivate the depositing of the Medical Archive in Medline. In addition to these facts, I was reminded of the incredible activities related to the preparation and printing of 47 books and monographs out of a total of 98 in B&H in the war period 1992-1995, and their list is in the attached tables. Those war publications were created in various ways. Very important collection of published monographs are printed during wartime written by very famous scientists from Golden Arabic Ages: Ibn Sina, Ibn Haitham, Ibn Rushd, Ibn Nafis, Al Biruni, Ar Razi, which has been forgotten, translated by famous professors Sakir Sikiric and Hamdija Karamehmedovic until 1962. In addition to these facts, I was reminded of the incredible activities related to the preparation and printing of 4 scientific journals out of 8 biomedicine which today indexed journals in Bosnia and Herzegovina. Very important item from wartime was recording documetary movie "Amputation or Reconstruction in Wartime Conditions" recorded by Izet Masic and Zoran Ridjanovic which made in 1994 and showen in Lisbon during MIE '94 Conefernce as one of war miracles. Finaly, during wartime in B&H Avicena organized and published Proceedings of ten scientific meetings held in sieged Sarajevo and all presented papers were published and deposited in PubMed Central database. Total amount of published books and monographs during past thirty years is more than 200, and, also published papers by Avicena during 30 years in four Avicena Publisher's journals have number more than 15,000 papers writen at least by 60,000 authors, from over 50 countries from all continents, and almost a half of them are stored in most influential indexed databases. It is incredible job of one very small publisher from small countriy.

The application of circular economy principles in water supply systems has been increasingly studied recently. Concrete experiments and practical implementations in the industry are being carried out with the aim of cost savings, energy production, and material and energy recovery from wastewater treatment processes. In this context, the aim of this paper is to identify some measures that water utilities can take to enhance sustainability and reduce environmental impact. The paper provides a brief overview of the opportunities for water utilities to act on water, materials, and energy.

The analyzes carried out in this research were performed on meadow and mountain honey samples from Bosnia and Herzegovina. The geographical origin of the analyzed honey samples is the area of Mount Majevica in the Tuzla Canton and the area of Livno, Canton 10, Sarajevo, Sarajevo Canton and Vlašić, Central Bosnia Canton. Honey samples were collected from 8 different localities. During the analysis, all honey samples were up to one year old. With the aim of testing the antioxidant capacity of honey, the polyphenol content and total antioxidant capacity were determined. The total antioxidant capacity of honey was determined by the indirect FRAP (Ferric Reducing Antioxidant Power) method, and the polyphenol content by the Folin-Ciocalteu method. The results showed that there is a significant correlation between the antioxidant capacity of the analyzed honey samples and the content of polyphenols in them. In order to compare the antioxidant activity and polyphenol content of pure honey samples (without additives) with honey mixtures (additions: ginger, garlic, sweet wormwood, propolis), mixtures were prepared for all samples, namely 5 mixtures of honey and ginger; 5 mixtures of honey and garlic, 5 mixtures of honey and sweet wormwood and 3 mixtures of honey and propolis. Analyzing the results, a comparative analysis of the polyphenol content and total antioxidant capacity in honey samples before and after the addition of wormwood, ginger, garlic and propolis was performed, and the influence of the mixture's standing time on the tested parameters was also examined. The results of these analyzes showed that additives to honey significantly affect its antioxidant activity and polyphenol content, and that standing the prepared mixtures can lead to an additional increase or decrease of the tested parameters.

Adhesive bonding is a well-established technique for joining materials. This article deals with the challenges of bonding metals, such as aluminium alloy EN AW-5754. To improve the strength of bonded joints, suitable surface preparation prior to bonding is essential. In this work, the surface of the aluminium alloy using three different epoxy adhesives was subjected to two different methods of surface preparation, such as laser cleaning and sanding by hand with sandpaper. The adhesion properties of the bonded surface were determined by measuring the surface roughness parameters (Ra and Rz) for different surface preparations as well as the mechanical property (tensile lap-shear strength). It was found that the bond strength of the aluminium alloy changed depending on the surface preparation and adhesive used, indicating that using the same adhesive and material with different preparation methods can lead to significant variations in bond strength. Therefore, choosing an appropriate surface preparation method that is suitable for the parts to be bonded and their surface roughness is crucial as it increases the strength of the bonded joints.

The additive technologies such as 3D printing are an important part of all branches of industry, primarily due to the possibility of production parts with complex geometries. The aim of the research presented in this paper is the analyze of joining 3D printed polymer parts with adhesive. Furthermore, the aim of this research is to analyze the strength of lap adhesive joints under different loads. FDM technology, PLA materials and two-component epoxy adhesive were used to fabricate the testing specimens.

This paper aims to present the effects of the MIG welding on the mechanical properties of a buttwelded joint of dissimilar aluminium alloys 2024-T351 and AA 6082-T6. Aluminium alloy 6082 T6 is well weldable by classical fusion welding processes (MIG and TIG), while aluminium alloy 2024-T351 is almost non-weldable. For the welding of these two Al alloys, the MIG welding was used on an 8 mm thick sheet using filler material 4043A (AlSi5) and a mixture of argon and helium as a shielding gas. The influence of MIG welding on the obtained structure and mechanical properties of the welded joint was analyzed. The assessment of the mechanical properties of the welded joint of dissimilar Al alloys was performed by Vickers hardness testing, tensile and bending tests of the welded samples.

In this paper, the variability of morphological (stem height, stem basal diameter, proportion of pith, wood and bark) and wood anatomical characteristics (fiber length, fiber diameter, fiber lumen diamater, double cell-wall thickness, vessel diameter, wood rays width and height) of three Salix alba clones (B-44, 347 and NS 73/6) and one Salix viminalis clone both in the control plot and in the site contaminated with a mixture of heavy metals (As, Cd, Cr, Cu, Ni, Pb) was investigated. The observed results showed that individuals of all four clones had significantly higher average values of stem height and stem basal diameter at the control plot compared to the polluted site. As for the proportion of pith, bark and wood, heavy metals caused an increase in the share of pith and a decrease in the share of bark and wood in all clones with the exception of clone NS 73/6. The analysis of wood fiber dimensions showed that the values of all parameters were higher at the control site with the exception of fiber lumen diameter where higher values were observed for clones B-44 and NS 73/6 at the polluted site. Higher values of vessel diameter were recorded for all clones at the control plot, while wood rays width of all individuals was greater at the contaminated site. Regarding the wood rays height, only Salix viminalis showed higher value at the polluted site. These results confirmed that pollution-induced heavy metal stress significantly altered the morphological and wood anatomical characteristics of all researched clones and that it may affect their utility properties.

We study the significance of the common trusted relay assumption in quantum networks. While most practical implementations of quantum networks rely on trusted devices, the question of security without this assumption has been rarely addressed. Device independent security attempts to minimize the assumptions made on the quantum hardware, entanglement based methods try to avoid relays to the extent possible, and multipath transmission improves robustness and security by enforcing the attacker to conquer more than just a single intermediate node. Common to all these past studies is their focus on the physical layer and direct connections. We describe an attack from the networking and routing layer. Assuming at least one node that is not perfectly tamper-proof, meaning that an attacker has established a foothold to read traffic from the inside, we show how to exploit the eavesdropping detection mechanisms of the quantum key distribution (QKD) devices to cause traffic redirection over the vulnerable node, thus defeating security under the trusted node assumption. We experimentally demonstrate how the attack works on networks of different size and topology, and thereby further substantiate the significance of the trust assumptions for end-to-end security of QKD networks.

The application of conventional electric arc welding in argon protection (TIG welding process) has limited possibilities. These limitations are primarily related to the thickness of the welded material and the need to prepare the groove for their welding. Overcoming these limitations in TIG welding was done by using activating flux, so the procedure was named ATIG (A-TIG) welding. The paper presents the results of research into the application of activating fluxes in welding austenitic stainless steel 316L with a thickness of 6 mm. By using the BC-31 and QuickTIG melters of different chemical bases, we compare the mechanical properties of the welded joints, as well as with the welded joints of the same material obtained using the conventional TIG procedure. The results show that the best mechanical properties are possessed by welded joints realized by the ATIG process using a mixture of activating fluxes BC - 31 (50%) and QuickTIG (50%) (green + white flux).
