Previous research on archaeological skeletal remains in Bosnia and Herzegovina rarely included odontological analysis. The objective of this research was biological profiling through odontological analysis (dental morphological characteristics, estimation of sex and dental age at death) in medieval archaeological skeletal remains samples from Krešića greblje in Paoča (Čitluk municipality, Bosnia and Herzegovina). After the excavations of the archaeological site, odontological analysis was performed before genetic analysis. The sample comprised 22 permanent teeth from 6 individuals. Odontological analysis included odontometric estimation of sex, estimation of age at death by two morphological methods, and an analysis of dental traits and dental pathology. Genetic analysis was used for sex determination. The results of odontological analysis classified all individuals as adults, with estimated age at death 20-25 in one individual, 30-35 in three individuals, 35-45 in one individual, and one individual older than 45 years of age. Odontometric sex estimation was in high concordance with sex determination by genetic analysis, and correctly classified five individuals’ sex (four females and one male). In one individual odontometric sex was assessed as female while genetic analysis revealed male. Morphological dental traits and dental pathology were investigated as well, adding to a better understanding of the odontological characteristics of the medieval population in the area of Bosnia and Herzegovina. Sex and dental age estimation given by odontological analysis provide fast and cost-effective information, and should be performed as an auxiliary before genetic analysis.

<p><strong>Introduction. </strong>The adoption of correct walking patterns is an indicator of the locomotor system readiness to establish optimal interaction between body force and the surface, and the way of creating pressure exerted by the feet during the walking cycle. The aim was to examine how the speed and characteristics of the terrain affect the distribution of force and plantar pressure during the gait of children with different levels of physical activity.</p> <p><strong>Methods.</strong> A prospective comparative study included 150 students aged 11&ndash;12 years and their parents from Banja Luka. According to the protocol, each group of subjects walked at average and maximum speed on flat and 5% inclined terrain. For the purposes of the research, the Physical Activity Questionnaire PAQ-C (The Physical Activity Questionnaire for Older Children), a survey questionnaire for parents, measurement of anthropometric parameters and Zebris strips (Zebris Medical GmbH, Germany) were used for gait analysis.</p> <p><strong>Results.</strong> When walking at maximum speed in inactive subjects, the maximum force on the left (F(148) = 14.878, p &lt; 0.001) and right (F(148) = 8.204, p &lt; 0.001) heel decreased, while in moderately and highly active subjects it grew moderately. In highly active subjects, the highest value of maximum pressure was registered (d = -1.41 for the left leg and d = 1.36 for the right leg). When the slope of the terrain changes in inactive subjects, the maximum force on the front part of both feet decreased (F(148) = 5.043, p = 0.008, d = 0). The influence of terrain characteristics was such that walking on a 5% incline almost as a rule had greater effects on inactive children, while moderately and highly physically active children gave an adequate response when walking on the 5% incline.</p> <p><strong>Conclusion.</strong> Urbanization and new developments in society impose the need to involve children in organized activities so that children acquire the skills and demonstrate the competence they face in their environment.</p>

Introduction Much has been written and spoken about telemedicine since about two decades including an article in this journal at the start of the pandemic. It took a global catastrophe to enforce its usage across the world in various medical specialties. Telemedicine however remains unstructured, unregulated and lacks uniformity. Discussion This article highlights the practical learnings and opinions of the authors who provided over two thousand video consults and asynchronous telemedicine services through the entire pandemic. It includes lessons learnt from emerging economies where pediatric rheumatologists are scarce. Pediatric rheumatology, which relies heavily on history, musculoskeletal and skin examination is aptly suited to exploit telemedicine in its synchronous and asynchronous forms. Pediatric tele rheumatology could temporarily address the shortage and uneven distribution of specialists in vast parts of the globe, besides serving as a method of triage and shared care with the primary physician. Reduction of direct and indirect costs and family/primary physician education are additional benefits. There also exist challenges for all stakeholders and it is important to address the latter. Conclusion The learnings of the pandemic suggest a vital role for telemedicine in the practice of pediatric rheumatology. This is a fertile area for research and consensus building by international and national pediatric societies and issue position statements like some adult bodies already have. The authors speculate a hybrid system of care in the not-so-distant future.

This paper investigates the integration of fuzzy logic and neural networks for disease detection using the Matlab environment. Disease detection is key in medical diagnostics, and the combination of fuzzy logic and neural networks offers an advanced methodology for the analysis and interpretation of medical data. Fuzzy logic is used for modeling and resolving uncertainty in diagnostic processes, while neural networks are applied for indepth processing and analysis of images relevant to disease diagnosis. This paper demonstrates the development and implementation of a simulation system in Matlab, using real medical data and images of organs for the purpose of detecting specific diseases, with a special focus on the application in the diagnosis of kidney diseases. Combining fuzzy logic and neural networks, simulation offers precision and robustness in the diagnosis process, opening the door to advanced medical information systems

Red mud is the main by-product of the production of alumina according to the Bayer process. It is a highly alkaline, brick-red suspension. It is characterized by a diversity of chemical and mineralogical composition. The main elements in red mud are Fe, Al, Si, Ti, Na, Ca, and they account for about 90% of the mass of the mud. In addition to these, a large number of other components can be found in minor quantities. Most elements are present in the form of oxides and hydroxides in various minerals. The demand for aluminum is constantly growing, the amount of discharged red mud is continually increasing. The annual amount of red mud produced globally, is already estimated at 200 million tons, and further growth is expected. High production rates and only minimal and sporadic utilization of red mud have resulted in the accumulation of large quantities of disposed red mud, so that the global red mud stockpile is estimated at more than 5 billion tons. In addition to financial costs, the disposal of red mud also poses certain risks to the environment. For this reason, the safe disposal of red mud is one of the main concerns of all alumina producers. Reducing the amount of red mud that is disposed of, and consequently reducing the risks and costs, requires constant efforts to find procedures for its valorization. The possibilities of valorization of red mud are diverse. It has been shown that red mud can be successfully used in many areas, such as construction, metallurgy, chemical industry, environmental protection, agriculture, etc. Analyzing the patents related to the use of red mud, it can be observed that 12% of the patents refer to the wastewater and waste treatment. The heterogeneous composition of red mud indicates the possibility of its application as a composite sorbent. The application of red mud as a low-cost sorbent has been extensively investigated, and favorable results have been obtained in the sorption of metals and metalloids, radionuclides, phosphates, nitrates, fluorides, dyes and phenols, etc. In order to increase the sorption capacity of red mud and obtain a more environmentally friendly sorbent, various treatment techniques are applied. These treatment techniques can modify the physical and chemical properties, which can lead to a change in alkalinity, specific surface area and porosity, a change in the number of active sorption sites, and its surface charge can also be changed. Modifications of red mud to remove various types of pollutants have shown promising results. Many studies have shown that red mud can be used as an efficient and low-cost sorbent for removing heavy metal cations from solutions, such as Pb2+, Cu2+, Zn2+ , Cd2+, Ni2+, Co2+, Sr2+, Cs2+, as well as for the treatment of waste water and leachate from landfills and mines. During the removal of heavy metals from solutions using red mud, various mass transfer phenomena occur: physical and chemical adsorption, surface precipitation, co-precipitation, ion exchange, precipitation, complexation, hydration, dissolution, etc. Despite the numerous possibilities of application and the benefits that arise from it, we still do not have a significant utilization of red mud.

The level of radio frequency radiation is followed by the growth of the new telecommunication technologies and the needs of the user. In order to prevent increasing of exposure over doses of electromagnetic radiation permitted for the general population, it requires to planing the construction of antenna systems and examine the living as well as working environment in their surroundings. City zones are potentially the most vulnerable on the exposure to high-frequency non-ionizing radiation, described below with examples of sensitive locations in Banja Luka such as the vicinity of schools, kindergartens and the hospital center. Review of data and their analysis in order to determine environment contamination level in the Republic of Srpska with non-ionizing electromagnetic radiation is the primary goal of this study. The measurement methods and theoretical assessment tools used for detection and prediction of these physical pollutants, which tend to grow permanently due to lifestyle, are also presented.

Water is a unique and irreplaceable natural resource of limited quantities and uneven spatial and temporal distribution. All life forms and all human activities are more or less related to water, clearly showing the importance of the relationship with water. It is a necessary resource in households as drinking water, washing and food preparation, in agriculture for irrigation, and in industry it plays an important role in almost all industrial processes. Economic development and urbanization lead, on the one hand, to a large increase in water demand, and on the other hand to the threat to water resources and the aquatic environment. Water can thus become a limiting factor in development, a threat to human health and the sustainability of natural ecosystems. Until recently, there was a centuriesold illusion of water inexhaustibility, and the concept of minimum investments for the purification of used water and water protection in general appeared. Much of the water used is not purified before it is discharged into watercourses and thus pollutes the water mass and reduces the resources of drinking water. Providing enough drinking water is one of the world's most important issues today. Therefore, it is especially important for every society to balance these relations and devise policies and strategies for the regulation, exploitation and protection of water resources.
