The World Health Organization (WHO) released guidelines for physical activity (PA), sedentary behavior, and sleep for children under 5 years of age in 2019, but there are no reports on the adherence to the guidelines in southeastern Europe. This study aimed to: (i) determine the proportion of preschool children (aged 3-5 years) who met the WHO guidelines and examine the feasibility of the proposed protocol for the SUNRISE study in Bosnia and Herzegovina (B&H), and (ii) define sex-, and urban/rural-living-specifics in movement-behaviors, anthropometrics, gross-motor-skills, fine-motor- skills, and cognitive-skills. The sample comprised 115 preschool children (63 girls and 52 boys), residing in urban (n = 66) and rural areas (n = 49) from B&H. Participants were tested on movement behaviors (PA, sleep time, screen time) by accelerometry and comprehensive questionnaires. Body height, weight, body mass index, executive function, fine-, and gross-motor skill, and cognitive function were also measured. The results showed that PA-, sleep duration-, and screen time guidelines were met by 64%, 74% and 53% of children, respectively, while only 23% of the children met all three guidelines on movement behaviors. Boys exhibited higher PA than girls, but no differences in gross- and fine motor skills and cognitive functioning were recorded between the sexes. Children living in urban and rural environments did not differ in any of the studied variables. Results evidenced preschool children from B&H being in line with other samples globally about study variables. Although PA was higher in boys than in girls it was not translated to differences in motor skills. Further studies on larger samples and other environments are warranted.

The primary goal of this research was to determine the differences in kinematic parameters between the first and second serves in tennis among the elite players of the German league. The sample of respondents in this research consisted of 30 elite male senior players of the German League who have "Leistungklasse" from 1 to 7. The kinematic parameters that were analyzed are: Height of ball impact (KPVUL), Racket speed (KPBRE), Ball speed (KPBLO), The angle at the elbow joint of the arm that hits the ball (KPULZ), Oscillation of the vertical projection of the center of gravity of the body (KPOVP), Jump height (KPVSK), Ball launch height (KPVIL), The point of contact between the ball and the racket "sweetspot" (KPMLR), Ball rotation "Top spin" (KPRLO). The video recording required for kinematic analysis was acquired with two Casio EX-F1 digital cameras at a frequency of 200 images per second. The camera was placed at an angle of 900 in relation to the recording plane, and they were at a distance of 10 m. Space calibration was performed with the help of a calibration frame (200 x 200 cm). We have installed Zepp Tennis Smart Sensor 2.0 in the handle of the Wilson Pro Staff RF97 Autograph racket, using the Zepp Tennis application software. "Kinovea" software was used for service analysis and obtaining kinematic parameters from video recordings. By analyzing the results of the T-test for independent samples, it can be seen that there are statistically significant differences in five of the nine analyzed kinematic parameters : KPBRE – kinematic parameter of racket speed (Sig.=.000), KPBLO – kinematic parameter of ball speed (Sig.=.000), KPULZ – kinematic parameter angle in the elbow joint (Sig.=.000), KPMLR – kinematic parameter point of contact between the ball and the racket (Sig.=.000), as well as a variable KPRLO – kinematic parameter of ball rotation (Sig.=.000). Larger numeric values in variables: KPVUL – kinematic parameter ball impact height, KPOVP – kinematic parameter of oscillation of the vertical projection of the center of gravity of the body, KPVSK – kinematic parameter jump height and KPVIL – kinematic parameter ball impact height, show a difference but it is not enough to be statistically different. Key words: tennis, kinematic analysis, racket speed, Zepp sensor

Today, tourism represents a strong and important economic branch, whether it concerns economically developed and underdeveloped countries as well as developing countries. It can increase employment in almost all countries, regardless of their level of development. Today's moment is marked by pronounced global crises, which again have a strong negative impact on the economic and social aspects of society, both globally and locally. Tourism, due to its characteristics and the positive effects it achieves in the process of realizing all activities in its area, can greatly reduce the percentage of unemployment in local communities. This positive effect of reducing unemployment is reflected in the possibility of employment for all categories of the unemployed, and particularly vulnerable groups of the unemployed such as people with disabilities, women, young people, the long-term unemployed, etc. Encouraging tourism in states or certain regions can have a favourable positive effect on employment within the territory. the same. For countries and regions that have developed tourism and that do not have pronounced problems with unemployment, activities through tourism increase the country's balance of payments as additional income through exports. Underdeveloped regions and countries and developing countries, by increasing activities through tourism, in addition to being an important source of income, realize a particularly important positive effect through the reduction of unemployment rates in them. Many developed countries, among which Austria is the leader, as a highly developed tourist destination for a long time, institutionally, have realized and use the potential offered by tourism to increase employment and actively use it to reduce the unemployment rate. Unfortunately, in our country and its tourist regions, where tourism is often one of the most important economic branches, this has not been done and they still record high rates of unemployment. Tourism in Bosnia and Herzegovina and Sarajevo Canton is a sector that can make a significant contribution to faster economic development. In our country and its regions and cantons, there are great potentials for increasing tourism activities, which will generate a greater number of jobs in tourism as well as tourism-related economic branches. To successfully solve the problem of unemployment in Bosnia and Herzegovina, its regions and cantons, positive experiences of tourism development through selective forms of tourism can be used, also using models of successful experiences from the world and the countries of the European Union. Keywords: tourism, unemployment, selective forms of tourism, European Union unemployment, Sarajevo Canton unemployment.

The World Health Organization (WHO) released guidelines for physical activity, sedentary behav-iour, and sleep for children under 5 years of age in 2019. In response to these guidelines, this study aimed to determine the proportion of preschool children (ages 3-5 years) who met the WHO guidelines. The time spent in physical activity, sedentary behaviour and sleep were objectively measured using accelerometer (ActiGraph wGT3x-BT). Screen time and sleep quality were assessed via parent questionnaire. Focus groups were con-1 ducted with parents and childcare staff to determine the feasibility of the protocol. The results showed that only 23% of the children met all three guidelines, and compliance rates varied for each guideline. The physical activity time guideline was met by 64% of children, the sleep duration guideline was met by 74% of children, and the screen time guideline was met by 53% of children. Only a low proportion of children met the WHO guidelines. The methods and devices used in this pilot study proved to be feasible and this has paved the way to conduct the main SUNRISE study in Bosnia and Herzegovina.

The primary objective of this study is to analyze the self-assessment of the mental and physical health of young women from the effects of programmed recreational activities in a three-month period. The sample is composed of 35 women (20 - 40 years old). For a sample of variables in the assessment of mental and physical health, standardized instruments were used: THE HAD scale - Hospital Anxiety and Depression Scale (for mental health assessment) and EQ thermometer (for physical health assessment) The results of the overall condition of all participants before the start of the experimental procedure, 24 participants had no symptoms of depression, 8 participants had a borderline condition, and 3 participants with depressive disorder. After three months of recreational treatment, 30 of the participants have no symptoms of depression, 3 participants have borderline condition and 2 participants with depressive disorder. When it comes to the self-assessment of anxiety in the initial state, it was noted that 26 participants of the experiment had no signs of anxiety, 6 participants had a borderline state of anxiety, while 3 participants had anxiety disorders, of which 2 participants slightly above the limit state and one participant with a particularly high number of points indicating a more severe state of anxiety. At the end of the experiment, 31 participants had no signs of anxiety, 4 had a borderline state and 1 person with a severe anxiety condition. Before the start of recreational activities, one participant rated their physical health as extremely poor and 3 people rated their health as poor. The largest number of participants before the experiment, 16 of them, rated their physical health slightly above average, 10 women rated their physical health as excellent and 5 women rated themselves the best imaginable physical health. After the experiment, only 4 participants estimated lower and average self-health, above average 6, 20 women claimed to have excellent health and 5 participants in the experiment claimed to be in the best physical health imaginable. Keywords: Women, recreation, self-assessment, depression, anxiety, physical health.

The past decade within Bosnia and Herzegovina and thus in the Sarajevo Canton has shown that tourism has become a significant segment of the economy with a pronounced constant positive growth.

Abstract The security of using applications in cloud services and on the Internet is an important topic in the field of engineering. In this paper, two laboratory tests for data transmission protection, specifically designed for different security analysis techniques, are presented and explained. During lab tests on public Wi-Fi networks from the MIDM (“Man in the Middle”) attacks, various monitoring techniques were applied, using a special lab test scenario with Kali Linux penetration tools by creating an SSH tunnel on an Android mobile device. These test benches allow easy data capturing, and the captured data is processed using available software programs. Expected outcomes, practical improvement and security performance assessment are presented in detail, and considered in terms of their value in security engineering. The aim of this paper is to detect and overcome some of the weaknesses of the application of security protocols in a Wi-Fi network environment.

This study was conducted on a sample of 40 senior and junior male and female karate fighters, chronological ages 18 to 27 from the Tuzla Canton, who are part of the regular training and competition process. The aim of this paper is to determine the differences in the motor reaction speed among the karate players with the same specializations but at different levels of competition, in conditions of fatigue induced by intense physical work in combination with complex visual signalization, which determines certain karate techniques. The study was conducted with the application of sophisticated technologies used in sport that enable the collection of data. The light stimuli was generated by the usage of the RIR 102 reaction meter and the quantitative valorization of the investigated parameters was carried out by a sophisticated kinematic analysis of the videos collected using two high-speed Casio Exilim EX-F1 digital cameras synchronized with the data from the Polar Team heart monitoring system. By processing and analyzing data, it was concluded that fatigue induced by situational conditions such as performing a series of strikes that simultaneously generate muscular, cognitive and sensory strain, produces negative effects on reaction time of the karate players. The intensity of limiting factors grows gradually in function of time, but is manifested differently in relation to the international and state level of competition.

Study aim was to analyze the kinematic parameters of the body of the examinees, without competitive experience in skiing, in order to determine the competitive efficiency. The participants in this research were 23 male students from the Faculty of physical education and sport, aged 22±6 months, who attended the classes in the subject alpine skiing. Examinees were divided into two categories, according to duration of the course run, in order to determine whether there is the differences in body segment parameters during giant slalom turn. Using Independent Samples t-test we see that the examinees differ on a statistically significant level in variables duration of the turn p=0.000, duration of the course run p=0.000 and inclination of the body p=0.030, and that the differences are in favor of faster examinees. The analysis of the results in this research has shown that there is a relation between the measured body segment parameters and duration of the course run, or that the technique of skiing has a direct impact on the competition in alpine skiing.
