This study seeks to test the existence of the crowding-out (orin) hypothesis in a sample of 17 Emerging Europe countries divided in two panels. The study employs a panel autoregressive distributed lag (ARDL) model based on three estimators, Mean Group Estimator (MG), Pooled Mean Group (PMG) and Dynamic Fixed Effect (DFE), in order to evaluate the of stability of short run and long run coefficients using consistently compiled public borrowing and private investment data between 2000 and 2019. The empirical findings of the paper generally confirm the existence of a crowding out effect in both long run and short run in European post-transition countries, and in the long run for European transition countries. More specifically, elasticity of private investment with respect to public debt is greater in the European transition countries than in the European post-transition countries. However, the findings on the crowding out (in) effect of government spending and economic growth on private investment are mixed and conflicting in both the long run and the short run. Accordingly, the study recommends that selected countries should reassess their austerity agendas employed for lowering debt levels, and follow new strategies for managing public debt burden.

The aim of this research is to determine the differences between the aerobic functional abilities of football players from different positions in the team, which should serve as a starting point in planning and monitoring the training process of football players. VO2max, as a basic parameter of functional abilities, was obtained by applying a laboratory progressive test on the treadmill. The sample of respondents was composed of 57 respondents (GOD = 22.47 ± 3.78SD), football players of clubs competing in the first and second leagues of Serbia from the area of Vojvodina, of which 8 goalkeepers, 16 defensive, 17 midfielders and 16 attackers. To test the functional capabilities (oxygen consumption - VOmax), we used a test of progressive continuous load on the treadmill with increasing load per minute through a "breath-by-breath" gas analyzer (Quark PFT ErgoCPET, Cosmed, Italy), which gave data on ventilation and spiroergometric parameters of the subjects by different positions in the team. Anthropometric measures of body weight- (TM) and body height- (TV) were applied to test the morphological characteristics of the subjects. SPSS 20.0 software package was used for data processing. In order to determine the statistically significant differences of the measured variables between football players by positions, a one-factor anova of different groups, the level of statistical significance (p <0.05) was used. The obtained results of maximum oxygen consumption indicated that there is a statistically significant difference in aerobic abilities between goalkeepers and players in other positions, and they are certainly a consequence of the physiological requirements placed before them and the different training process. The highest mean value of VO2 max had midfielders (53.3 ± 1.9 ml / kg / min), followed by attackers (52.9 ± 4.4 ml / kg / min), defensive players (51.8 ± 3, 3 ml / kg / min) while the lowest values were recorded in the goalkeeper (50.5 ± 1.8 ml / kg / min). There is a logical conclusion that the need for running midfielders is the greatest, and the goalkeeper the least, and that the results are the result of training processes and different requirements for individual positions in the team.

In the logistics world, special attention should be given to warehousing systems, cost rationalization, and improvement of all the factors that affect efficiency and contribute to smooth functioning of logistics subsystems. In real time industrial practice, the issue of evaluating and selecting the most appropriate forklift involves a complex decision-making problem that should be formulated through an efficient analytical model. The forklifts efficiency plays a very important role in the company. The forklifts are being used on a daily basis and no logistical processes could be done without them. Therefore, it has been decided to determine their efficiency, which will contribute to the optimization of the process in this logistics subsystem. This study puts forward an integrated forklift selection model using Data Envelopment Analysis (DEA), Full Consistency Method (FUCOM) and Measurement Alternatives and Ranking According to the Compromise Solution (MARCOS) methods. Five input parameters (regular servicing costs, fuel costs, exceptional servicing costs, total number of all minor accidents and damage caused by forklifts) and one output parameter (number of operating hours) were first identified to assess efficiency of eight forklifts in a warehousing system of the Natron-Hayat company using the DEA model. This step allows sorting of efficient forklifts which are subsequently evaluated and ranked using FUCOM and MARCOS methods. A sensitivity analysis is also performed in order to check reliability and accuracy of the results. The findings of this research clearly show that the proposed decision-making model can significantly contribute to all spheres of business applications.

Despite many efforts to diagnose and treat preventable cardiovascular diseases (CVD), more specifically to detect known risk factors, these diseases continue to be the leading cause of morbidity and mortality. Bosnia and Herzegovina belongs among the high-risk countries with standardized death rate (SDR) of 385 per 100 000 inhabitants in 2018. Two leading causes of death are acute myocardial infraction, with rate around 90 deaths per 100 000 inhabitants and stroke with the rate around 80 deaths per 100 000 inhabitants in one year. Both incidents are preventable. Digital interventions are necessary for strengthening of the healthcare system. Benefits of eHealth could be seen in transmission of customized health information for different audiences: transmission of health-event alerts to a specified population group; transmission of health information based on health status or demographics; alerts and reminders to clients; transmission of diagnostic results (or of the availability of results) or even notifications and reminders for appointments, medication adherence, or follow-up services. Successful implementation of digital health requires multidisciplinary approaches, from mass dissemination of recommendations through public health education programs directly in the field, to clinical treatments for patients. All this requires the involvement of numerous actors, from the strategic to the operational level of management within the healthcare system in the country.

The authors present the life and work of prof. dr. Radoslav Živić - Rade who will be remembered as an exceptional pediatrician, professor of lofty pride and morals and a writer who occupies a special place in the contemporary Serbian narrative milieu in which it is difficult to find a prose writer and sensitivity to the meaning of words and the ability to visualize and fruitful grafting in the literary art of Serbia.

Radiological examination methods in the diagnosis of kidney disease, thanks to their objectivity and their capabilities, have taken their place in the diagnosis of urosystems and kidney disease. Radiological methods of examination in the diagnosis of the kidney are numerous and diverse. They are sovereign, dominant and unrivaled. However, the dangers that lurk and threaten in their application, especially ionization and complications from iodine contrast agents, indicate and say that they should be used in strict indications, with well-educated staff and with full protection measures. The aim of this paper is to show and point out the number, variety, advantages and disadvantages of radiological methods of examination in kidney diagnostics. The material and method of work is the experience gained in the profession based on urographic examinations and other radiological methods of examination of the urogenital system, primarily in 18,000 IVUs performed in the period 1994-2021. at the Center for Radiology of the University Medical Center Nis and numerous literal announcements of authors and co-authors written in domestic and foreign journals. The results of the work are shown illustratively, with pictures - nephrocalcinosis, renal cyst, pheochromocytoma, VUR V 0 , kidney tumor, color doppler of the renal artery, a series of native and contrast spiral CT tomograms of the kidney. The development of radiological techniques in recent decades has enriched radiological diagnostics with new diagnostic possibilities. Therefore, we received new radiological images, in which our results are compatible with numerous literal world releases. In conclusion, the authors point out that radiological methods in the diagnosis of kidneys are indispensable and, among other methods of examination, indispensable.
