Background: The creation of corneal flap is considered to be the most critical part of laser in situ keratomileusis (LASIK) surgery. Currently, flaps can be created with mechanical micorkeratomes or femtosecond lasers. Objective: To analyze and compare flap characteristics created with two different methods for flap creation in Laser in situ keratomileusis (LASIK). Methods: This was a retrospective study. The thickness and morphology of the flap were compared between the two mechanical microkeratomes (group I – Moria M2, group II – Moria SBK One Use Plus) and femtosecond laser (group III – Ziemer Femto LDV). Central flap thickness was measured intraoperatively, while the flap profile was measured with anterior optical coherence tomography at two axes (90° and 180°) and 5 measuring points on the first day, the first week, and one month after the surgery. Results: Central flap thickness was 110.91±15.79 micrometers (µm) (80-164 µm) in group I, 98.08±13.33 µm (65-136 µm) in group II and 103.52±13.89 µm (66-138 µm) in group III. Anterior optical coherence tomography revealed a meniscus-shaped flap in all three groups at both axes (90° and 180°). The least variability in flap thickness was observed in group III (±6 µm). Conclusion: All three methods of flap creation provide good shape and thickness reproducibility. Ziemer Femto LDV femtosecond laser had the least variable flap thickness in a single flap. Mechanical microkeratomes had slightly lower performance.

Spatial structure is the horizontal and vertical arrangement of individual trees. It affects many processes in the stand such as stability, production and regeneration. Stand structure parameters are used to describe spatial structure on experimental plots. The paper presents methods that describe the stand structure through three levels of diversity related to position, species and size. Research has been conducted on two experimental plots from the area of Olovo. Referent trees and their competitors were selected on both experimental plots, and competitors were defined by referent tree distance. The aim of this paper is to describe the spatial structure on experimental plot of European beech (Fagus sylvatica L.) and experimental plot of European beech and Scots pine (Pinus sylvestris L.). Indicators of spatial diversity, dimensional diversity and diversity of tree species have been determined to achieve that aim. For each experimental plots are described: horizontal tree distribution (Poisson Distribution, Clapham's Variance – Mean Ratio and Morisita's Index of Dispersion), diameter differentiation (Diameter Differentiation by Füldner and Dominance Index by Hui et al.), species diversity and structural diversity (Species Profile Index by Pretzsch) and species intermingling (Species Intermingling Index by Füldner). Obtained results show that the stand structure of both experimental plots deviates from random distribution. Dimensional diversity parameters indicate stronger intensity of competition for beech trees. Analysis of species diversity showed that beech trees occur in groups or patches, and the other represented species mix more intensive.

Background: The world was struck with a pandemic accompanied by maybe one of the most popular words out there right now, which is COVID-19. It has affected every aspect of life imaginable, especially in the medical sector particularly in our case dental care. Objective: This study goes on to analyse and assess the impact of COVID-19 on dental care in Bosnia and Herzegovina, varying from the staff, patients, supplies/equipment, and finances. Methods: An online survey and over-the-phone surveys were conducted, bringing in raw information to help with this study. Results: In total there were 10 different dental offices that information was obtained from. About 90% say that the pandemic has affected their patient flow, obviously due to some restrictions and regulations. And 60% say that the cost of PPE has increased since the pandemic started, while 40% said otherwise. Other data can be found in the rest of the study. Conclusion: Entering into the pandemic, dental practices quickly started to realize the seriousness of this situation, changing the way they do normal everyday work to accustom to this “new norm”. During such a problem, both sides have to participate to act upon accordingly to bring health and safety for everyone.

Various viruses can hide within fluid and solid structures and thus successfully cross different distances, causing the spread of viral infections. Analytical modeling of the triple treatment of virus within a small liquid droplet and within a solid porous particle is the basic research polygon of this paper. The three-stage treatment aims to maximize the efficacy of deactivating viruses indoors. In order to achieve this, viruses undergo treatment by infrared heating, ultraviolet deactivation and ionization–electrostatic deactivation by negative ions. When the droplets are treated with infrared heating, incomplete evaporation occurs, reducing their initial diameter by 10 times; an initial diameter of droplets is 0.01 mm, 0.03 mm and 0.05 mm. Thermal inactivation of viruses inside the droplets is almost negligible, due to short exposure time and a maximum temperature of 100 °C. On the other hand, when solid porous particles are heated to a much higher temperature at the same exposure time, this causes significant thermal inactivation of viruses inside them. Reducing the diameter of the droplet (due to evaporation) by 10 times causes a multiple increase in UV-C deactivation of viruses inside the droplets. The effect of UV-C radiation on viruses within solid porous particles is not included in this paper.

‘’Back then, in the Corona…’’ As numbers of the COVID-infected were rising across Bosnia and Herzegovina (BiH), over the summer and into the autumn of 2020, this phrase appeared as a common opening to individual stories and a new temporal reference that replaced “the war” as the major landmark in personal and collective lives. Corona had already become the past, equated with the days of the lockdown, even though more COVID-19 infections came after the lockdown ended. After lockdown, the death...

Length of the primary forest roads in the Federation of BiH is 11.821,00 km that includes the categories of public and forest truck roads. Cantonal Public companies for forest management in the Federation of BiH are responsible for the design, construction and maintenance of forest truck roads. The starting point in the analysis related to forest truck roads is to determine the quality and quantity of the existing forest road network. This paper deals with data for all forest truck roads in the territory of Federation of BiH that in total includes 2.907 forest truck roads. The following data were collected and analysed: pavement type, pavement width, longitudinal slope and traffic load per year per 24 h. The analysis of these elements can serve as the basis for categorizing of forest truck roads into primary, secondary and access roads, as well as starting point in planning process related to the maintenance works and future forest road construction.

Possibilities to use unmanned aerial vehicles (UAVs) are rapidly growing. With the development of battery technologies, communication, navigation, surveillance, and autonomous systems in general, many UAVs are expected to operate at relatively low altitudes. Thus, the problem of UAV noise impact on human health and well-being will be more pronounced. In this paper, we conducted noise measurements of two UAVs of different performance (quadrotor and hexarotor) in flying up and down, hovering, and overflight procedures. Respondents of good hearing who were confirmed by audiogram measurement and had participated in the survey during UAV noise measurement gave their subjective assessments on the UAV noise perception. UAV noise measurements and subjective respondents’ assessments were analysed and related. UAV noise analysis showed that the parameters measured at the same measurement point for the hexarotor were higher than those for the quadrotor in flying up and down and flying-over procedures. Low frequency noise was present in the noise spectrum of both drones. Participants were able to distinguish between the noise of UAVs and had a generally more negative experience with the hexarotor. Regardless of the noise perception, more than 80% of the respondents believe there are more pros than cons for UAV introduction into everyday life.

Background: Carotid endarterectomy (CEA) is an effective and safe treatment of stenosed carotid arteries, and is a preventive operation with well-defined indications. It is associated with a loss of the baroreceptor reflex and postoperatively increased hemodynamic parameters. Objective: The aim of the study was to confirm the sensitivity of baroreceptors and the impact on arterial pressure and heart rate in unilateral and bilateral eversion carotid endarterectomies. Methods: A retrospective study was conducted with 30 patients treated with E-CEA in local anesthesia at the Clinic for cardiovascular surgery from December 2019 to May 2021, due to stenosis of the carotid arteries. Patients were divided into two groups: 15 patients in group A (patients with unilateral E-CEA; 15 patients in group B: patients with bilateral E-CEA). Results: Out of the total of 30 patients included in the research, 15 patients in groups A and B respectively, there were no statistically significant differences in regards to gender (p= 0,245) and preoperative risk factors: smoking (p=0,449); hypertension (p=0,388); diabetes (p= 0,714); hyperlipidemia (p=0.388), coronary disease (p=0.461) and symptomatic stenosis of the carotid arteries (p=0.449). Noted were the statistically significant differences in values of systolic and diastolic pressure on the 3rd postoperative days in patients with bilateral E-CEA (p=0,001; p=0,001), a statistically significant difference in the heart rate was not found in the analyzed groups in the postoperative period (p=0,225; p=0,994). Conclusion: This study identified statistically significant differences in values of systolic and diastolic pressure in the early postoperative period. In his period, early detection and correction of these hemodynamic disorders are needed.

Abstract We are witnessing an increasing frequency of illegal actions and fraud in the business of legal entities, which directly reflects on the quality of information presented in financial statements. Internal audit does not primarily deal with the audit of financial statements, but through verifying the application of accounting policies and procedures it helps to gain reasonable assurance that the financial statements are reliable and that they are presented fairly. The role of internal audit in the fraud detection process is reflected in the fraud risk assessment in the internal audit planning process, and through performing work engagements to detecting them. In this paper, we will present risk assessment techniques, which the internal auditor can apply in quantitative and qualitative assessment of fraud risk, and in identifying priority areas/audit processes. The aim of this paper is to point out the importance of the role of internal audit, through the application of techniques, tools and prescribed responsibilities for risk assessment, in the process of detecting fraud in companies that cause incalculable damage on a daily basis.

Background: Dentine hypersensitivity (DH) is a frequent clinical problem that represents a long-term painful discomfort for the patients, and for the dentists, it represents a diagnostic and therapeutic challenge. Objective: The aim of the research is to verify the effect of the treatment with diode laser SiroLaser Blue (660nm) of DH alone or in combination with different impregnating agents. Methods: Fifty patients were included in this research, separated into five groups. All the patients have been asked to define the level of dentine hypersensitivity using VAS (0-10). The first group was treated with Fluor Protector, the second group after the application of Fluor Protector has undergone irradiation with SiroLaser Blue (660nm), the third group was treated with impregnating agent Vivasens, the fourth group, after the application of impregnating agent Vivasens, has had SiroLaser Blue (660nm) irradiation. The fifth group has just been treated with SiroLaser Blue (660nm). The efficiency of the treatment was checked using VAS for every group immediately after the conducted treatment, after 7 days and 1 month. Results: Our results showed that all of the desensitizing agents used in the research alone or in combination with a diode laser (660nm) have shown a reduction of DH. The difference has been proven statistically significant in mean values by groups and examinations. Vivasens and diode laser irradiation have provided the best results in the review of mean values after the first examination and one month after the treatment of DH (p<0,05). In our research, the application of diode laser alone has not proven superior to other treatment methods that have been used in the research. Conclusion: Vivasens plus diode laser irradiation has provided the best results even after one month since the treatment of DH.

Abstract Abdominal injuries are rare in sports, but even minor traumas may result in potentially life-threatening injuries. The most frequent abdominal injury is abdominal wall contusion, following by blunt injuries of the kidneys and spleen. The cases of blunt abdominal injuries in soccer are rarely reported in the literature. We present a case of a grade IV splenic laceration in a 10-year-old soccer goalkeeper caused by the blunt abdominal trauma sustained during the gameplay. The trauma was successfully treated with a nonoperative management approach.

Background: Mobile pharmacies are special organizational units or infrastructures that serve to supply medicines to remote communities or are stationed on ships or as such exist during war conflicts on the battlefields to provide first aid to the wounded and to provide the necessary medicines. The establishment of mobile pharmacies is regulated by the law of each state and only preparations approved by law can be found in it. There are also regulations for the good storage and warehousing of these drugs. Objective: The aim of this article was to provide an overview of the available literature on the topic “Mobile pharmacies through history”, which shows the development and progress in the structure and function of mobile pharmacies throughout history. Methods: This is an descriptive study based on the searched available literature from the on-line databases regarding to present a historical overview of mobile pharmacies during the most significant war events in Europe and the USA. Results and Discussion: Mobile pharmacies were first mentioned in Egypt and the Roman Empire, but it was not until 1500 that military and ship’s doctors began using them, and wealthy nobles had their own boxes of medicines, which they carried on long voyages. Mobile pharmacies became more and more popular, so in the 18th century, practical manuals on the use of the contents of the box began to be published. The importance of a mobile pharmacy was shown in the wars, where people, before their appearance, died due to the impossibility of providing first aid on the battlefield. The advanced medicine and pharmacy that developed on land, greatly affected the health care at the sea. The constant incidence of infectious diseases, poverty and inadequate nutrition, insecurity of navigation and long voyages are the main reasons why sailors often fell ill and were exposed to injuries at work. A situation like that required that the problem of health protection on ships gets solved in accordance with the then principles of medicine and pharmacy. Conclusion: Authors demonstrated the importance of mobile pharmacies in treating and providing medical protection on boat trips. Regarding the ship’s pharmacies, pharmacists have the role of supplying ships with medicines, conducting training for captains and ship staff, advising shipping companies and captains on equipping ship pharmacies and advising on the preparation of national regulations and national ship pharmacy supply policy.
