      <title>1. Introduction</title>
      <p>
        The principles of openness pervade the research cycle at all stages and promote cooperation and
exchange of results, leading to systemic changes in the theory and practice of scientific research
implementation [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. Cloud-oriented systems of open science appear as tools for supporting open
research, with the help of which the activity of virtual learning/research teams is ensured [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ]. Access is
provided to a flexibly organized pool of electronic resources, specialized software supplied as a service,
means of support and management of an educational/scientific project, services design, visualization
and presentation of data, statistical processing of results, semantic and syntactic analysis of texts, etc.
      </p>
      <p>
        In the modern information and educational space, cloud-oriented systems of open science are among
the leading trends. These ICTs provide support for such innovative forms of organization as collaborative
learning and research through shared access to the ICT environment and software for solving tasks [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ];
adaptive cloud-oriented data processing systems [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ], in particular, big data [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ]; adaptive cloud-oriented
learning and research platforms deployed based on educational institutions or their units [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ]; scientific
and educational information networks, platforms and infrastructures, in particular, the European Open
Science Cloud (EOSC) [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ]; cloud services and electronic resources for educational and scientific purposes
that are available for use [
        <xref ref-type="bibr" rid="ref8 ref9">8, 9</xref>
        ].
      </p>
      <p>
        In connection with the pandemic situation and then the war in Ukraine, the contacts of teachers
and students were severely limited [
        <xref ref-type="bibr" rid="ref10">10</xref>
        ]. This complicates the preparation of students who come to the
university with weak knowledge, as well as the training of graduates and postgraduates due to the lack
of contact with their teachers and supervisors. In the university, self-study is a typical activity process
[
        <xref ref-type="bibr" rid="ref11">11</xref>
        ]. This creates good prerequisites for the integration of IT in learning in virtual online learning
environments [
        <xref ref-type="bibr" rid="ref12">12</xref>
        ]. In practice, however, there is only general-purpose software and a lack of IT tools
to create personalized learning environments and systems [
        <xref ref-type="bibr" rid="ref13">13</xref>
        ].
      </p>
      <p>In this regard, the study of various tools for the formation of cloud-oriented virtual systems to support
the processes of educational and scientific cooperation falls into the focus of the project’s research “V4
Educational Academic Portal for Integrating IT into Education” (EDUPORT), which is carried out in
2022-2023 with the support of the Visegrad Foundation (Visegrad Fund, https://www.visegradfund.org/),
and member of which are educational and scientific institutions of Slovakia, the Czech Republic, Poland,
Hungary and Ukraine.</p>
      <p>The relevance of the work is due to the need to increase the eficiency and efectiveness of the
development of ICT competence of university teachers due to the broader use of tools and technologies
of open science in the learning process, particularly with the use of cloud-oriented solutions. The
introduction of cloud-oriented systems and services of open science is an essential prerequisite for
improving the qualifications, training and retraining of educational personnel for active professional
activity and self-realization in a high-tech society, the use of innovative methods and teaching tools,
the implementation of innovative forms, methods and approaches to its organization.</p>
      <sec id="sec-1-1">
        <title>1.1. Analysis of recent studies</title>
        <p>
          The principles and conceptual foundations of open science are highlighted in international documents
relating to the features of the formation of the European Research Area, and the concept of open science
[
          <xref ref-type="bibr" rid="ref14 ref15 ref16">14, 15, 16</xref>
          ]. Scientific and methodological issues of creating and developing a cloud-oriented educational
and scientific environment in the context of open science priorities are considered by Lytvynova
[
          <xref ref-type="bibr" rid="ref17">17</xref>
          ], Bykov and Shyshkina [
          <xref ref-type="bibr" rid="ref18">18</xref>
          ]. The question of the formation and development of competencies of
open science is highlighted by Schmidt et al. [
          <xref ref-type="bibr" rid="ref19">19</xref>
          ]. The problem of forming virtual systems of open
science in educational institutions, introducing the principles of open science into teaching and research,
and creating open educational and scientific environments requires further study.
        </p>
        <p>
          Cloud tools have transformed the learning environment, enabling massive data processing, sharing
and reusing research results, greater scalability of computing power, and service-oriented
architecture [
          <xref ref-type="bibr" rid="ref20">20</xref>
          ]. This approach provides open, collaborative, project-oriented learning. The Institute for
Digitalization of Education of the National Academy of Educational Sciences of Ukraine developed
basic approaches to form open education models [
          <xref ref-type="bibr" rid="ref21">21</xref>
          ]. These research results form a theoretical and
methodological foundation for further work in this direction; in particular, it is advisable to use them
in the development of open science systems as a new stage in the implementation of open education
along with the broad implementation and use of these approaches in all areas of the education system.
        </p>
        <p>
          In [
          <xref ref-type="bibr" rid="ref22">22</xref>
          ] the important issues of open science such as mapping and visualization of scientific domains
are considered. The ICT tools of open science such as Bibexel, Pajek, VOSViewer, programmes used for
processing and visualization of bibliographic and bibliometric data are analysed. The implementation
of these tools to support the activities within the framework of the IRNet research network project
shows the relevant tendency.
        </p>
        <p>
          The research methodology aims to implement the general principles of open science, such as open
access, data, research methods, communication, and evaluation [
          <xref ref-type="bibr" rid="ref16">16</xref>
          ]. The cloud-oriented approaches
deliver useful tools for this purpose. The main features of cloud computing are the flexibility and
scalability of IT infrastructure, helping to achieve significantly higher eficiency in training within the
cloud-based learning and research environment [
          <xref ref-type="bibr" rid="ref18 ref23">18, 23</xref>
          ].
        </p>
        <p>
          The scientific and methodological study of the problems of forming a cloud-oriented educational
and scientific environment needs further development in the context of the priorities of open science
[
          <xref ref-type="bibr" rid="ref18 ref24">18, 24</xref>
          ]. In particular, in the aspect of using powerful platforms for storing and processing volumes of
scientific data, as well as flexible selection and scaling of computer capacities. Using cloud platforms
in combination with communication services creates much more opportunities for the functioning of
virtual scientific teams [
          <xref ref-type="bibr" rid="ref25">25</xref>
          ].
        </p>
        <p>Summarizing the experience of using cloud-oriented tools of open science to support the processes of
communication, joint work, adaptive content management, creation and use of electronic resources and
services in the course of educational and scientific cooperation in virtual teams, it can be argued that it
can be useful for further implementation in the domestic educational and scientific space, particularly
in a university teacher education.</p>

        <title>1.2. The research aim</title>
        <p>The work examines the justification and development of the use of cloud-oriented systems of open
science as one of the promising directions of supporting the activity of a virtual research team to
conduct educational and scientific activities of team members.</p>

      <title>2. The research results</title>
      <p>In the information and educational environment, there are new models of the organization of educational
activities, which are based on innovative technological solutions for the design of the environment,
among which the hardware and software of adaptive information and communication networks, and
cloud solutions play a significant role.</p>
      <p>The issue of adapting and adjusting the tools and services of the information technology
educational environment to the needs of users to maximally realize the pedagogical potential of using the
most modern ICT, in particular, cloud-based, to achieve improvement in learning outcomes, as well
as improvement of the process of scientific research activities of teachers, development of joint work
skills, requires the introduction of innovative approaches. These approaches should provide the most
appropriate ways of organizing access to educational software, in particular, based on cloud-oriented
approaches that belong to the leading models of organizing the infrastructure of the educational
environment and also become a catalyst for introducing innovative methods and approaches in educational
practice.</p>
      <p>In this regard, the study of various means and tools for the formation of cloud-oriented virtual
systems of open science to support the processes of international scientific cooperation falls into the
focus of research of the project “V4 Educational Academic Portal for Integrating IT into Education”
(V4 EDUPORT), which is carried out in 2022-2023, and a participant of which, along with educational
and scientific institutions of Slovakia, the Czech Republic, Poland and Hungary, was the Institute
for Digitalization of Education of the National Academy of Educational Sciences of Ukraine, which
represents Ukraine.</p>
      <p>The V4 EDUPORT project aims to combine the knowledge gained in educational and scientific
institutions of the V4 countries to create an educational portal, appropriate IT software and common
infrastructure for creating educational packages and multilingual content for this portal in the blocks
EDU-TUTOR, EDUPACKAGES and EDU-IT (part of EDUPORT will be publicly available, part available
to partners).</p>
      <p>The main result of the EDUPORT project was the creation of a cloud-oriented IT support system
for research activities of a virtual scientific team. The system consists of network ICT infrastructure,
educational software WPadV4 and PIKS channels – online application (PHP/MySQL) – and personal
information and communication system of project participants.</p>
      <p>
        The WPadV4 application software was installed on Windows virtual desktops for ten computers of
researchers and project partners. Although this solution is quite simple since WPads can be created
and used even by individuals with a low level of IT skills, solutions like this have not been considered
before. This is because the WPad application, although a database application, was designed around a
non-relational paradigm; the novelty of this decision is confirmed by the registration of utility model
8787 in the patent ofice [
        <xref ref-type="bibr" rid="ref15">15</xref>
        ]. As a result, knowledge modelling using WPad tables allows you to create
educational and informational solutions to be applied in the teaching and research process.
      </p>
      <p>WPad was developed as a personal IT support tool for research areas such as learning analytics,
digital libraries, overcoming language barriers and computer-supported collaborated learning (CSCL).
Although some CSCL issues can be addressed in terms of ofline collaboration with students (e.g.,
students creating collaborative e-learning material to bridge knowledge gaps), this was also necessary
to address in a study focused on the collaboration of an international teaching team.</p>
      <p>It should be emphasized that WPad is special software that uses simple tables into which the teacher,
researcher, and/or students manually, copy, or automatically paste educational content. The key point
here is that unlike text-based computer files (.doc, .pdf), WPad tables only work with selected content
required for lectures, exercises and self-study. Content is also stored in files (.dbf) that you can use to
transfer information to other WPad files, send, store in the cloud, and create HTML files for eLearning.</p>
      <p>Thus, the implementation of a simple solution is considered, which is based on an interdisciplinary
approach and uses the universal author’s software WPad for modelling the processes of knowledge
management in education and research. The approach is based on the use of WPad tables, in which
only specially selected educational content is inserted, while the most recent studies are characterized
by the use of standard computer files with unselected content. Thus, there is an opportunity to achieve
a higher pedagogical efect. Using this software, participants in the educational process can create,
transfer and consume content faster. In addition, it is a cheap and convenient solution, since the basic
version of WPad only requires Windows and an Internet connection. The presented system should not
be considered as a competition to existing software but as an additional tool for the personal IT support
of teachers and researchers.</p>
      <p>The V4 EDUPORT project aims to combine the knowledge gained in educational and scientific
institutions of the V4 countries to create an educational portal, appropriate IT software and shared
infrastructure to create educational packages and multilingual content for this portal in the blocks
EDU-TUTOR, EDUPACKAGES and EDU-IT (part of EDUPORT will be publicly available, part available
to partners).</p>
      <p>
        Processing of knowledge and context-controlled data tables is performed by the WPadV4 database
application, authored by S. Svetsky [
        <xref ref-type="bibr" rid="ref26">26</xref>
        ]. Because this software is based on the abstraction of metadata
and content, it allows users to process content in a default structure. Thus, the user can create tables of
knowledge to build educational texts and material for lectures and exercises.
      </p>
      <p>The principles and priorities of open science were followed by using a cloud-based learning and
research platform to support collaborative processes. These included communication, information
retrieval, data exploration, sharing of results and methods, and content management, as all required
materials, such as instructional materials, articles, training materials, document collections, etc., are
currently supported and available on the platform. Adaptive content management was supported by
the research tool WPadV4, which was used to process available data based on a robust model. Thus, all
data collected during the study was valid, accessible, compatible and reusable for all partners. It was
supposed to ensure the openness and flexibility of scientific cooperation processes.</p>
      <p>
        In particular, thanks to the involvement of cloud-oriented platforms in the educational process, and
the deployment of various types of corporate cloud services on them, it is possible to create specialized
environments that are mostly focused on solving certain types of problems. For this, there may be
no ready-made publicly available services, while the corporate cloud-oriented environment can be
adapted, configured and oriented to any type of task that arises in the practice of research. It provides
the most expansive opportunities for creating unique authors’ methods and organized systems for
solving particular problems. It will make it possible to achieve positive changes in the implementation
of teachers’ educational and scientific activities, improve its qualitative and quantitative indicators,
and introduce new forms and models of its organization. It is advisable to use such platforms as, for
example, MS Azure, AWS or others [
        <xref ref-type="bibr" rid="ref27 ref28 ref29 ref30">27, 28, 29, 30</xref>
        ] to support the deployment of corporate cloud-oriented
platforms. The experience of their use, in particular, in the project “V4 Educational Academic Portal for
Integrating IT into Education”, shows that it has a positive efect on both learning outcomes and the
development of scientific research, improving the level of their organization, and increasing eficiency.

      <title>3. Conclusions and discussion</title>
      <p>It has been established that thanks to the broader involvement of tools and services of cloud-oriented
platforms as well as various types of corporate cloud services in the educational and scientific process
of institutions of higher education, it is possible to achieve positive changes in the implementation of
this activity, improvement of its qualitative and quantitative indicators. Application of new forms and
models of learning and research activities has a positive efect on both the results of training and the
development of scientific research, improving the level of their organization, and increasing eficiency.</p>
      <p>The training component with WPadV4 software was developed and tested based on a cloud server
deployed on AWS (Amazon Web Services). It paves the way for the development of methods for
deploying educational and scientific components in the learning and research environment of higher
education institutions.</p>
      <p>The main result of the EDUPORT project was the creation of a cloud-oriented IT support system
for research activities of a virtual research team. The system consists of network ICT infrastructure,
educational software WPadV4, methods of creating educational packages and accompanying educational
materials and their multilingual support, and PIKS channels – an online application (PHP/MySQL)
developed to implement personal information and communication systems. It supposes the adjustment
for the learning and research needs of the project team or the learning process. These tools may be
useful to support scientific and educational information networks of open science; communications;
joint work; adaptive content management; and creating and using electronic educational resources in
the process of organizing educational and scientific cooperation in virtual teams. The question of the
selection and integration of services, the study of their various components, and the most appropriate
ways of application in open science systems, the combination of intelligent technologies and network
cloud services is a perspective for further research.</p>
      <p>The cloud-based approach is aimed at development of the systems that are open and flexible. Among
its advantages is the possibility to transform and modify the educational environment if needed. That’s
why the selection and choice of useful learning and research tools need further investigation.</p>
      <p>
        The European Open Science Cloud (EOSC) needs special attention in improving both the content and
technological components of the systematic support of the teacher training process. It is a pan-European
infrastructure that unites electronic resources and services developed within the framework of European
research projects and not only them, classified according to scientific fields and types of activities. The
toolkit posted on the EOSC portal is quite diverse, and the list of services is extensive. The portal
provides clear instructions for registration, navigation, search for services, settings, and access. The
methods of using the services of the European cloud of open science, in particular those developed in
[
        <xref ref-type="bibr" rid="ref24">24</xref>
        ], in the educational and scientific process, require further development and implementation. It is
necessary to provide support to teachers in implementing new practices.
      </p>
      <p>Considering the existence of diferent models of using cloud services, it is worth paying attention to a
balanced choice of the most appropriate solution suitable for each case, for a specific situation, both for
a collective and an individual user. The choice of the SaaS model (software as a service) in this regard
can be justified by the fact that these services are the most accessible. However, they require a thorough
market analysis and a pedagogically balanced choice of a software application, with the help of which
it would be possible to achieve the necessary educational or scientific goals. These tools can be used
both in the activities of an individual teacher and in the individual or collective work of a project team.</p>
      <p>The experience of using cloud-oriented open science tools to support international scientific
cooperation in educational institutions is summarized: communication; joint work; adaptive content
management; supporting the processes of creating and using electronic educational resources in
organizing educational and scientific cooperation in virtual teams. It can be used to further develop open
science systems in the national educational and scientific space.</p>
      <p>The question of the selection and integration of services, the study of their various components,
and the most appropriate ways of application in open science systems, the combination of intelligent
technologies and network cloud services provides a perspective for the further development and
implementation of open science approaches.</p>
