2018 № 4 Assessment of financial flows and expenditures in HIV/AIDS infection in Tajikistan
In Tajikistan, despite the measures taken, there are still problems in reducing the spread of the epi-demic and covering the HIV/AIDS prevention and treatment measures related to HIV/ IDS financing. Development of measures to ensure long-term financing of national programs and strategies related to HIV/AIDS response. The need to finance HIV/AIDS programs in the long term until 2020 was developed on the basis of a mathematical model for assessing the epidemic’s development and forecasting. Based on the mathematical model, assessing the development of the HIV/AIDS epidemic shows that in the case of sufficient financing of all basic services within a budget of $129 million for the period until the end of 2020, about 8,360 new cases of infection and the preservation of 101,700 DALYs. Sufficient funding for all basic services related to the prevention and treatment of HIV/AIDS will effectively achieve the goal of preventing the further spread of the HIV / AIDS epidemic by 2030

2021 № 8 Evolution of information systems
In medical organizations, information systems solve the following tasks: the ability to receive and store information, quick access to it and its transmission, the ability to generate various reports, the availability of specialized workplaces of medical workers, etc. Information systems are gradually evolving, turning from a tool capable of solving the simplest management tasks into a tool capable of solving the entire range of management tasks encountered in the practice of a medical organization at all levels of management. The purpose of the study is to describe the four stages of creating information systems, highlight the characteristic features of the functioning of information systems at each stage, as well as highlight the list of the main management tasks that are being developed at the selected stage and ways to solve them. The main attention was paid to the development of information systems of medical organizations working with the children’s population.
Results. The first stage of the development of information systems began with the use of computer technology in the practice of medical organizations and was reduced to the fact that programmers of both medical and third-party organizations began to develop tasks, the totality of which later became known as “creating an information system” of a medical organization. The goal of the second stage is already the transformation of information systems of medical organizations in order to describe production processes in terms of a process approach and implement them in the form of software modules. The third stage of building information systems is the stage of describing the work of a medical organization based on mathematical models in order to justify the optimal solution of the production tasks available in it. The fourth stage of building information systems is the construction of an “information system that implements the functions of an intelligent management system of a medical organization”. The authors of the article give recommendations on the formalization of information available in a medical organization for the purpose of its
effective use by artificial intelligence.
Findings. Thus, an information system is a tool for solving management problems, its development as a tool for solving management problems requires knowledge of management theory, organization theory, process approach in management, methods of multidimensional statistical analysis and modeling methods, languages and modeling methods based on neural networks.
