The study considers trends and prospects for developing virtual (augmented) reality and civil transactions in relation to digital property. In jurisprudence, there is a need to determine the legal status of virtual and augmented reality to regulate legal relations in the digital environment. Legal relations using new digital technologies require the creation of new legislative approaches and rules of their legal regulation. The article dwells on the legal status of virtual (augmented) reality and determines the methods of regulating legal relations in the sphere of digital property. The study utilized methods for collecting single and multiple facts in order to identify the main trends in the civil circulation of digital assets, as well as private law methods. The methods of generalization, concreteness, induction and deduction reveal the legal nature and main features of virtual (augmented) reality and digital property. The paper highlights the specifics of virtual reality and civil transactions in relation to digital assets. The research has concluded that the sale, exchange and other actions with digital objects in virtual reality have distinctive features, while digital property has also unique characteristics since it is involved in civil circulation and legal relations.

As a survey-type article, the paper reviews various digital topological utilities from digital covering theory. Digital covering theory has strongly contributed to the calculation of the digital k-fundamental group of both a digital space(a set with k-adjacency or digital k-graph) and a digital product. Furthermore, it has been used in classifying digital spaces, establishing almost Van Kampen theory which is the digital version of van Kampen theorem in algebrate topology, developing the generalized universal covering property, and so forth. Finally, we remark on the digital k-surface structure of a Cartesian product of two simple closed $k_i$-curves in ${\mathbf{Z}}^n$, $i{\in}{1,2}$.

The significance of welding quality cannot be overstated in ensuring the structural integrity of steel constructions. However, welding operations are inherently intricate, influenced by numerous variables. This paper introduces a novel welding digital twin framework grounded in a dynamic knowledge base. This framework serves to visualize the welding procedures and forecast optimal welding parameters. Such insights facilitate informed decision-making by operators, thereby enhancing both the quality and efficiency of welding processes. Furthermore, the study employs the welding of H-beam steel as an example, wherein a digital twin welding model is established, based on which the overall welding quality can be improved.

The article reports the results of an investigation on the practice of providing digital scholarship services at Vietnam National University Ho Chi Minh City, Vietnam. This study is part of an ongoing research project entitled Developing a digital scholarship service framework for universities at Vietnam National University Ho Chi Minh City. It employed a qualitative research approach through in-depth interviews with 31 individuals who are university managers, library managers, lecturers, and postgraduate and undergraduate students from six member universities and Central Library of Vietnam National University Ho Chi Minh City. Research results show that some digital scholarship services have been provided at Vietnam National University Ho Chi Minh City. However, they have not been yet systematically implemented and have not met users' needs. Lack of needed resources such as space, technology infrastructure, human resources, finance, and stakeholder support are among major challenges in developing digital scholarship services. The management of existing digital scholarship services is fragmented without a clear policy for developing digital scholarship and supporting services. The study contributes to the existing knowledge by adding substantially to current understanding of the practice of providing digital scholarship services in Vietnam's universities in the transition period, from state control to autonomy, which has not been much addressed in previous research. Furthermore, this study can be a useful reference for higher education institutions in developing countries regarding implementation of digital scholarship services.

본 논문은 AI(: Artificial Intelligence) 시대에 따른 대학 교양교육으로 디지털 리터러시 교육의 필요성과 방향성에 대해 고찰하였다. 디지털 환경에서 일상적인 문화에 대한 보편적인 교육이 바로 디지털 리터러시라고 볼 수 있으며, 단순히 디지털 기기를 사용할 수 있는 능력이 아니라 디지털 사회의 시민에게 필요한 역량들을 함양하는 것으로 범위가 확장되고 있다. 본 논문에서는 대학 교양 교육과정이 시대적 변화를 반영하여 정보 문해 영역을 강화했지만, 아직 디지털 기기 사용 및 특정 프로그램 활용법을 학습하는 기술적인 측면에 편중되어 있음을 문제점으로 제시하고, 대학의 디지털 리터러시 교육의 방향은 디지털 기기 사용의 기술적·도구적 측면에 국한해서는 안되며, 디지털 기기의 사용으로 인해 발생할 수 있는 사회적 영향을 고려한 디지털 윤리에 중점을 둔 방향으로 이뤄지는 것이 바람직할 것이라고 제안하였다.

This study demonstrates some major traits of digital contents as information, playfulness, individuality, as satisfaction and commitment, user behavior as use intention. To make an empirical analysis the study, it is hypothesized that traits of digital contents, relationship quality, and user behavior. The major finding of this study can be summarized as follows, traits of digital contents are positively affected by satisfaction in relationship quality and use intention. Theoretical implication of this study are as follows. First, users wanted to choice only needed information. Second, users recognized digital contents as a part of life. So, user's ability is very important in this environment. According to this, business related with or interested in digital contents must have developed digital contents in variety aspect. Users must have concerned using digital contents, also.

The main purpose of the study is to determine the main aspects of the problem of socio-economic development in the conditions of the digital economy. The post-industrial era is characterized by the development of the electronic environment and the transition to an information civilization. In this regard, the developed countries of the world pay considerable attention to the development of the digital economy. However, there are a significant number of problems associated with this process. The country cannot be successful in the development of the digital economy in the absence of the necessary legal framework, an economic development strategy based on digital technologies. The research methodology involves the use of several theoretical methods for analyzing and synthesizing information. As a result of the study, the key problems of socio-economic development in the digital economy were characterized.

The manufacturing industry is continuously pursuing advanced technology and smartization as it converges with innovative technology. Improvement of manufacturing productivity is achieved by monitoring, analyzing, and controlling the facilities and processes of the manufacturing site in real time through a network. In this paper, we proposed a new OPC-UA based digital twin model for smart factory facilities. A testbed system for USB flash drive packaging facility was implemented based on the proposed digital twin model and OPC-UA data communication scheme. Through OPC-UA based digital twin model, equipment and process status information is transmitted and received from PLC to monitoring and control 3D digital models and physical models in real time. The usefulness of the developed digital twin testbed system was evaluated through usability test.
