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.

Digital Twin technology is rapidly transforming various industries by providing comprehensive virtual models that replicate physical objects or processes. In the context of agriculture, digital twin can be a game-changer. This technology can help in creating precise simulations of farming scenarios, thereby enabling farmers to make data-driven decisions and optimize farm operations. The potential benefits include improved crop yields, resource efficiency, and environmental sustainability. However, the implementation of digital twin technology in agriculture poses challenges, such as data management issues and the need for robust IoT infrastructure. Despite these hurdles, the future of digital twin in agriculture looks promising, with ongoing research and developments aimed at overcoming these obstacles.

A digital $(k_0,\;k_1)$-homotopy is induced from digital $(k_0,\;k_1)$-continuity with the n kinds of $k_i$-adjacency relations in ${\mathbb{Z}}^n$, $i{\in}\{0,\;1\}$. The k-fundamental group, ${\pi}^k_1(X,\;x_0)$, is derived from the pointed digital k-homotopy, $k{\in}\{3^n-1(n{\geq}2),\;3^n-{\sum}^{r-2}_{k=0}C^n_k2^{n-k}-1(2{\leq}r{\leq}n-1(n{\geq}3)),\;2n(n{\geq}1)\}$. In this paper two kinds of digital 8-pseudotori stemmed from the minimal simple closed 4-curve and the minimal simple closed 8-curve with 8-contractibility or without 8-contractibility, e.g., $DT_8$ and $DT^{\prime}_8$, are introduced and their digital topological properties are studied by the calculation of the k-fundamental groups, $k{\in}\{8,\;32,\;64,\;80\}$.

디지털도서관을 단순한 정보유통 구조의 한 부분으로 정의하지 않고 디지털도서관 그 자체를 자원의 생산, 유통 그리고 재생산을 위한 무형의 가치창출 행위로 인식하였으며 디지털자원의 속성을 해석함으로써 디지털도서관을 설계하였다. 즉, DRM(Digital Resources Management)의 가치를 디지털도서관으로 보았으며 그것을 전통적 도서관의 진화로 인식하였다. 이미 대학도서관들의 오픈액세스 자원생산이 이루어지고 있으며 클라우드 컴퓨팅 환경에서의 도서관 디지털장서 관리와 공유가 가능함을 보여줌으로써 출판이 가미된 디지털도서관의 가능성을 보여주었다.
