The aim of this paper is to analyze the relationship between the Fund for Social Security of Military Insurers and the Republic Health Insurance Fund through the aspect of more efficient use of health insurance funds. Analyzing this relationship, the system of health care in the Republic of Serbia and the health insurance system are essentially considered. Taking into account the specifics of the social protection of military insurers, efforts are being made to find out the direction and improvement of relations with the civilian health care system. Only the proactive relationship between the military and the civilian health system and the health insurance system is a condition of better health care for the insured of both funds, as well as more efficient use of health insurance funds. Health protection of the population is one of the most important social priorities and as such it must be given special attention. The right of the individual to health care, but also to other forms of protection, is realized within the framework of social insurance. Health care, and therefore the health insurance system of military insureds, developed in accordance with the specifics related to the military system itself. Fully respecting the autonomy of the said system, the development of insurance in this area evolved along with changes in the prevailing civilian health insurance system. The system of health care and health insurance is one of the most important systems in each country. The efficiency and cost-effectiveness of the functioning of this system is a challenge for every national economy. The goal that needs to be achieved is to achieve the best health care of the nation by means of available health insurance. The system of compulsory health insurance in the Republic of Serbia is implemented through a unique state organization - the Republic Health Insurance Fund. When it comes to health insurance and the protection of civil and military insurers, it is clear that these are two completely separate and independent systems that have a lot of common points and whose mutual cooperation and shared use of resources should lead to positive effects as a whole. The financial aspect, which is especially reflected through the health insurance system, is one of the most important factors because it directly affects the scope and quality of the entire health care system. Considering and analyzing the complexity of the mutual relations between the civilian and military health and social security systems, and consequently the health care system, some of the possible proposals have emerged for improvement of one of the most important aspects of every society - the health of the nation.

As a consequence of the measures taken to remedy the medical problem, there may be a bigger one economically, all over the world. The paper analyzes the consequences of the current economic crisis caused by the COVID-19 virus pandemic. The key economic consequences of the pandemic for companies but also for the economy have been identified. Entrepreneurs, small and medium enterprises, with the smallest liquidity stocks, are expected to feel the greatest consequences of the economic crisis. Taught by the failures of the Great Depression and the relative successes of the crisis in 2008, governments have already announced and launched massive programs to help businesses. At this moment, the supply of liquidity of deficient economic entities is a critical issue. The previous crisis showed that governments have tried and tested mechanisms for supplying liquidity to the financial sector, but transmission mechanisms to end-users were the Achilles' heel of the mechanism. We believe that success in finding adequate channels for the transfer of liquidity to economic entities with a liquidity deficit will be crucial for the character, length, and depth of the crisis. The paper offers a number of proposals for key necessary measures at the state level to overcome the observed economic disruptions. One of them is the request of the regulator, the other is the reaction of the state, but an important part must also come from the company. In addition, the research conducted by the questionnaire method for joint-stock companies from the Western Balkans resulted in a set of measures that serve as a basis for determining the gap in the required and current set of measures taken at the level of an individual organization.The aim of this paper is to point out that in the short term it is possible to stabilize the system through the application of macroeconomic and microeconomic measures.

Recent trends in the development of autonomous vehicles focus on real-time processing of vast amounts of data from various sensors. The data can be acquired using multiple cameras, lidars, ultrasonic sensors, and radars to collect useful information about the state of the traffic and the surroundings. Significant computational power is required to process the data fast enough, and this is even more pronounced in vehicles that not only assist the driver but are capable of fully autonomous driving. This article proposes speed and accuracy improvement of traffic sign detection and recognition in high-definition images, based on focusing on different regions of interest in traffic images. These regions are determined with efficient and parallelized preprocessing of every traffic image, after which convolutional neural network is applied for detection and recognition in parallel on graphics processing units. We employed different “You Only Look Once” (YOLO) architectures as baseline detectors, due to their speed, straightforward architecture, and high accuracy in general object detection tasks. Several preprocessing procedures were proposed, to achieve real-time performance requirement. Our experiments using a large-scale traffic sign dataset show that we can achieve real-time detection in high-definition images with high recognition accuracy.
