The subject of research in the article is the processes and technologies of communication management of infrastructural projects. The possibilities of using blockchain technology in the field of project management are considered. The goal of work: improving the information security of infrastructure projects. The risks of stakeholder communications will be reduced by increasing the security of data access and reducing the time for their processing, which in turn will provide more flexible project management. The tasks of the work: to analyze the current state of development of blockchain technology and conduct a comparative analysis of technology and modern generally accepted management methods, give examples of implementation, determine the advantages of blockchain technology in modern conditions; analyze the benefits of using smart contracts in communication management, apply the smart contract life cycle model in an infrastructure project. Research methods: systems analysis, design approach, structural modeling, instrument Geth, programming language Solidity. The following results were obtained. The main directions of development and implementation of blockchain technology are characterized, examples of the use of blockchain technology in various industries are collected and analyzed, the main advantages and disadvantages of the technology are identified, a comparative analysis of blockchain technology and classical project management methods is carried out, the possibilities of using blockchain technology in the field of project management are described, the main the possibility of implementing reasonable contracts, the advantages and disadvantages of reasonable contracts are identified, the advantages and disadvantages of the instrument of reasonable contracts are analyzed in comparison with the traditional approach. The smart contract life cycle model presents the creation stages, installation to the blockchain contract managing, and contract completion. Provided an example of the smart contract used for the complex financial project, which reduced the risk of project failures. Conclusion. The scientific novelty of the obtained results is in the improvement of the project management life cycle model through the further development of the smart contract model. This allows to increase information security, reduce possible risks and guarantee the implementation of an infrastructure project through the use of blockchain technology in comparison with classical project management methods.

AbstractSince 2020, the tourism industry worldwide has been devastated as a result of the COVID-19 pandemic. Governments across the globe imposed strict national lockdowns in order to curb the spread of the pandemic, with negative effects on tourism. This forced many tourism companies and organizations to turn to virtual reality (VR) to survive. As a consequence, numerous tourism scholars began to question whether VR would replace conventional tourism after COVID-19. The study aims is to address this concern and to determine if VR will be a substitute for conventional tourism or whether it can be considered as a tourism niche. It is a conceptional study which adopts a comparative analysis of conventional tourism models and VR. It uses two popular conventional tourism models, namely N. Leiper’s (1979) tourism system model and R.W. Butler’s (1980) destination life-cycle model. Based on this analysis, this paper suggests that VR will never be a substitute for conventional tourism, but should rather be considered a future tourism niche.

В исследовании определены требования к моделям жизненного цикла организации, позволяющим сформировать адекватную корпоративную систему управления проектами и получить максимальный эффект от ее использования. Выявлены наиболее подходящие для поставленных целей модели жизненного цикла. Определен состав и содержание компонентов корпоративной системы управления проектами на разных стадиях жизненного цикла организации. The application of various life cycle models in the company development is becoming more widespread. When a company realizes at what stage of its life cycle it is, it can adjust its behavior, avoid traps and develop the appropriate strategies. Relevant management decisions are to be made and specific management tools are required at each stage of the organization life cycle. Project management is no exception. A specific set of approaches and methods of project management is essential at each stage of the organization life cycle. A certain level of the project management system development is inherent to each stage of the organization life cycle. The organization life cycle theory and project management were the theoretical and methodological background of the investigation. The study presents the analysis of various models of the organization life cycle according to their features in the process of developing the corporate project management system and its individual components. The requirements to the life cycle model, which allows forming an adequate corporate project management system and get the maximum effect from its application, were determined. The life cycle models that are most suitable for the set goals were identified. These were the Adizes life cycle model and the Chernov model. The requirements for the components of the corporate project management system at different stages of the organization's life cycle were specified. The study found that the implementation of project management system components is most effective in the period from the stage of "youth" to the stage of "aristocracy" in accordance with the model of the Adizes life cycle. It is at these stages that it is essential for the company to introduce the methodology and formalize project and program management processes. The necessity for setting up a full-fledged project management system for the company appears at the stage of “stability” and it is at this stage that it has all the resources required for implementing the system.

RESUMO O objetivo foi analisar as intersecções entre os elementos dos modelos de ciclos de vida dos dados das iniciativas do DCC, DataONE e o CVD-CI. Trata-se de uma pesquisa descritiva, qualitativa e bibliográfica. Verificou-se que há correspondências entre etapas (nem sempre de um para um) dos ciclos de vida dos dados analisados. Foi possível constatar que o CVD-CI condensa várias atividades em uma única etapa, o que pode dificultar a sua aplicabilidade. De uma maneira geral, os modelos propostos ainda carecem de maior detalhamento para poderem ser aplicados diretamente por pesquisadores/curadores.Palavras-chave: Ciclo de Vida dos Dados; Curadoria Digital; Dados científicos; Tecnologia da Informação.ABSTRACT The objective was to analyze the intersections among the data life cycle model elements of the DCC, DataONE and CVD-CI initiatives. It is a descriptive, qualitative and bibliographical research. It was verified that there are correspondences between stages (not always one-to-one) of the analyzed data life cycles. It was possible to verify that the CVD-CI condenses several activities in a single step, which can hinder its applicability. In general, the proposed models still need to be further detailed so that they can be directly applied by researchers/curators.Keywords: Data Life Cycle; Digital Curation; Scientific Data; Information Technology.
