The article presents a software package that allows to support the design of teaching materials by a teacher of disciplines of the humanities and socio-economic cycle. The problems of the organization of didactic design by a university teacher with the need to compile directly by an expert teacher supporting lecture notes and other methodological materials, including the need to select a number of literary sources taking into account their specifics for different educational tasks and types of educational activities, are presented. The problems of adaptation and development of methodological materials to changes in the ontology of the subject area are discussed, for example, in connection with changing trends in the scientific environment, when established positions are transformed, which creates a problem for the teacher to additionally engage in didactic design and adjust teaching materials. Thus, there is an urgency of automatic analysis of text materials, which will significantly reduce the complexity of this process when developing, making changes and adapting courses of humanitarian and socio-economic orientation. The step-by-step process of transition from the competence-oriented requirements of the subject area to the functional requirements of the information system is analyzed, on the basis of which a decision-making model was formulated that closely imitates the process of didactic design, subject to automation, and allows using software tools to control its logic. The results of the infological and physical design of the system are presented, including a database model and a deployment diagram using an object-oriented modeling language. Methods and tools of software implementation of the application are discussed with justification of the relevance of their choice for the software solution of the task. The results of the system's operation confirm its functional suitability, and the results of testing allow us to judge a significant reduction in the complexity of the didactic design process by the teacher. The developed tool can be widely used both in the development of educational and methodological materials of the main literature, and for the methodological equipment of the organization of independent work of students.

The modern practice of defining administrative-industrial territories has formed the concept of «single-industry towns». Currently, there are many definitions of this phenomenon; however, the common criterion for classifying a town as a single-industry town is that its socio-economic development depends on the activities of one city-forming enterprise or several enterprises in the technological structure that operate within a single production and technological process. Such dependence for settlements with narrow specialization has a negative impact during the crisis situation at the enterprise or its liquidation. The negative consequences include a sharp increase in unemployment (including hidden one), aggravation of social problems, acceleration of population outflow to more developed cities/regions of the region/country, sharply reduced revenues to the local budget, which leads to the impossibility of independent development of the settlement. The problems of single-industry towns in the periods of economic crises are pronounced. Results. This paper has defined the criteria of single-industry towns, approaches to the identification of single-industry towns. In addition, the models and factors contributing to the sustainable socio-economic development of single-industry towns and domestic experience in the modernization of single-industry town settlements are identified.
