Due to its favorable geographical location, natural resources, attractive cultural and historical heritage, internationally recognized events, gastronomy, and status as a still relatively undiscovered destination for the leading emitting tourist markets, Bosnia and Herzegovina has the prerequisites for the successful development of tourism. Therefore, in the first decades of the 21st century, a continuous increase in domestic and foreign tourists was recorded in this country. However, the COVID-19 pandemic had a significant impact on tourism trends in the world and in Bosnia and Herzegovina. The pandemic crisis decreased the number of foreign tourists and tourism remittances. Given the potential of the tourism industry, this study aims to determine how the COVID-19 pandemic has altered trends and spatial patterns of tourism in Bosnia and Herzegovina. The spatiotemporal analysis revealed that this pandemic considerably lowered the size of the tourism industry in this country and affected spatial patterns of tourism flows, but by 2021 and 2022, the industry had already begun to recover. The results of the study provide new insights into tourism trends and the effects of the COVID-19 pandemic on the tourism industry and can serve for future tourism research and development in Bosnia and Herzegovina.

In this study, using the methods of spatial autocorrelation in geographic information systems (GIS), an analysis of the spatial distribution of mortality rates in Bosnia and Herzegovina was performed in order to identify high-risk areas with increased mortality and depopulation. Spatial analysis is based on the calculation of global (Global Moran’s I and Getis-Ord General G) and local (Anselin Local Moran’s I and Getis-Ord Gi*) statistical indices of spatial autocorrelation. The values of global statistical indices confirmed a clustering of high mortality values, while local statistical indices confirmed high mortality rates in the municipalities of northwestern and eastern Bosnia and Herzegovina. Conducted research provides an insight into spatial patterns of demographic processes, while results obtained by this research are significant for demographic development and future spatial demographic research in Bosnia and Herzegovina.

The aim of this research is to analyze the spatial distribution of the population ageing in Bosnia and Herzegovina and identify areas of the country that are particularly vulnerable to negative demographic trends. To achieve the goal of the study, data on the ageing coefficient and ageing index for the period 2013-2020 were used. The geospatial analysis of these indicators was performed using global (Global Moran's I and Getis-Ord General G) and local (Anselin Local Moran's I and Getis-Ord G*) indexes of spatial autocorrelation. The research results confirmed the clustering of both indicators. Ageing coefficient values are clustered in municipalities in western, northwestern, Eastern, and central Bosnia and Herzegovina. Ageing index values are clustered in municipalities in central, western, northwestern, and northeastern Bosnia and Herzegovina. This study provides insight into the research methods of spatial demographic trends and phenomena, and its findings can serve as a basis for future demographic research and development in Bosnia and Herzegovina.

The beginning of the 21st century in the Federation of Bosnia and Herzegovina (henceforth referred to as ?the Federation?) has been characterised by a decrease in the primary-school-age population. As such, the main objective of this work is to define and explain the factors that have influenced the decrease in the primary-school-age population in this part of Bosnia and Herzegovina. The research methodology applied in this work is oriented towards defining the degree of influence of demographic factors on the development of the primary-school-age population in the Federation. By using statistical methods and GIS analysis of statistical data, negative demographic trends were confirmed in the Federation at the end of the 20th and the beginning of the 21st century. These trends included intensive migration, a decrease in the total number of inhabitants, a decrease in the birth rate, an increased mortality rate, a decreased rate of natural population change, and the ageing of the population. Due to adverse economic, social, political, and other circumstances after 1995, population emigration has been intensified, most noticeably within the population aged between 20 and 40. The most important result of the research is the fact that the decrease in the natural population dynamics and intensive emigration are the most significant factors influencing the decrease in the primary-school-age population in the Federation. Such negative demographic trends influence the primary education system adversely. In the future, it will be necessary to plan and implement a population-revitalisation process as part of the federation?s overall population policy.

In this paper the age structure and the ageing population process in Bosnia and Herzegovina in the second half of the 20th century and the beginning of the 21st century is analyzed. The main reasons that caused changes in the age composition of the population and the population ageing in Bosnia and Herzegovina have been researched. The main causes of the population ageing in Bosnia and Herzegovina in the second half of the 20th century were primarily trends in fertility rates and secondarily trends in mortality rates. The economic growth of Bosnia and Herzegovina after World War II conditioned changes in the economic and educational structure of the population and with that the changes in the natural increase rates and migration balance. The war was the main cause of negative demographic changes in Bosnia and Herzegovina in the period from 1992 to 1995, and the post-war adverse socioeconomic, political and other circumstances have been the cause of negative demographic trends after 1995. The aim of this paper is to determine the level of population ageing in Bosnia and Herzegovina and the consequences this process could have on the demographic future of this country.

Introduction: Fractures of the proximal femur and hip are relatively common injuries in adults and common source of morbidity and mortality among the elderly. Many methods have been recommended for the treatment of intertrochanteric fractures. Material and methods: We retrospective analyzed all the patients with fractures of the hip treated with proximal femoral nail antirotation (PFNA) at the Clinic of Orthopedic and Traumatology, University Clinical Centre Tuzla from the first of January 2012 to 31 December 2012 years. The study included 63 patients averaged 73.6±11.9 years (range, 29 to 88 years). Fracture type was classified as intertrochanteric (Arbeitsgemeinschaft für Osteosynthesefragen classification 31.A.1, A.2 and A.3) and subtrochanteric fractures (Seinsheimer classification). Results and discussion: The ratio between the genders female-male was 1.6:1. There was statistically significant difference prevalence of female compared to male patients (p=0.012). There were 31 left and 32 right hip fractured. Low energy trauma was the cause of fractures in 57(90.5%) patients. Averaged waiting time for hospitalization was 3.2±7.5 days (range, 0 to 32 days). 44 patients were admitted the same day upon injuring. The average waiting time for the treatment was 3.6±5.7 days. The ratio between with or without co-existent disease was 4.7:1. During the three months postoperatively with ASA score 3 and 4 six patients died. There were no significant differences in deaths from ASA score 1 and 2 (p=0.52). Reoperation for the treatment of implant or fracture-related complications was required in three (4.7%) patients (infection, reimplantation and extraction). Three patient developed deep vein thrombosis. Statistically significant difference was found in the deaths in the first three months compared to the next three months (p=0.02). We found statistically significant difference between pre-injury and postoperative mobility score (p=0.0001). Conclusion: PFNA is an excellent device for osteosynthesis as it can be easily inserted. Moreover, it provides stable fixation, which allows early full weightbearing mobilization of the patient.

ABSTRACT Introduction: Fracture of the femoral shaft is a common fracture encountered in orthopedic practice. In the 1939, Küntscher introduced the concept of intramedullary nailing for stabilization of long bone fractures. Intramedullary nailing has revolutionized the treatment of fractures. Material and methods: The study included 37 male patients and 13 female patients, averaged 39±20,5 years (range, 16 to 76 years). Results and discussion: There were 31 left femurs and 21 right femurs fractured. 46 fractures were the result of blunt trauma. Low energy trauma was the cause of fractures in six patients, of which five in elderly females. 49 fractures were closed. Healing time given in weeks was 19,36 ± 6,1. The overall healing rate was 93,6%. There were three (6,25%) major complications nonunion. There were one (2%) delayed union, one (2%) rotational malunion and no infection. The shortening of 1 cm were in two patients. Antercurvatum of 10 degrees was found in one patient. There was no statistically significant reduction of a motion in the hip and knee (p<0.05). There was statistically significant in the thigh (knee extensors) muscle weakness (p<0.001). Conclusion: Intramedullary nailing is the treatment of choice for femoral shaft fractures.
