2003 년에 정부에서 여러 가지 활동과 2004 년 1월에는 산업자원부에서 'e- Learning 산업발전법' 을 공표함으로써 e- Learning 산업의 앞날이 밝아오고 있다. 하지만 아직은 전통적인 교육보다 e-Learning이 일반적으로 성과나 만족도가 떨어진다는 연구가 지배적이다 [1, 17] 이러한 상황에서 e-Learning을 확산한다는 것은 매우 어렵다. 이것은 e-Learning을 경험하는 학습자들의 만족을 통하여 e-Learning의 확산을 촉진할 수 있는데, 이를 위하여 e-Learning 환경에서 학습자들이 어떠한 요인들로써 만족을 느낄 수 있는지 알아보아야 한다. 학습자의 특성에 따라 만족도에 미치는 요인들을 찾아내어 학습자의 특성에 맞게 관리를 해줌으로써 온라인 환경에서 학습자들을 효과적으로 관리할 수 있어야 한다.

Impact of online social network to cyber community has increased much attention recently. The biggest challenge in fostering a social network is to the extent whether it helps to build human capital network or social community. We propose what critical factors influence the formation of online capital network. The study uses three independent factors as motivation, self disclosure, and interactivity and two dependent factors as knowledge sharing and strengthening relationships to create virtual capital connection. Data collected from 256 university students to test the proposed model. The results of the study shows that all hypothesis are supported except one with strengthening relationship. Implications and limitations of this research are discussed.

음악은 인류의 대표적인 예술로서 오랜 세월동안 사랑을 받아왔다. 그 오래된 세월만큼이나 인류가 만들어온 음악의 수는 방대하다. 방대한 음악이 IT기술의 발달과 인터넷의 확산을 통하여 온라인 음악시장을 형성하였고 음악은 디지털 음원으로 관리되게 되었다. 이러한 디지털 음원을 효과적으로 검색하기 위한 방법은 많이 연구되었다. 그리고 검색을 도와줄 대량의 디지털 음원 자료들을 저장하고 관리하는 기법에 관한 연구가 필요하다. 본 논문에서는 대용량 자료를 처리하는 기술로 관심 받고 있는 하둡을 통하여 이 문제를 연구하였다. 하둡의 맵리듀스, HDFS 그리고 HBase를 이용하여 음악 내용기반검색을 설계하였다. 본 시스템은 음악 검색 시스템을 관리하고 유지하는데 있어서 컴퓨팅자원을 절약함으로써 비용을 절감 효과를 얻을 수 있다.

Online shopping has transformed and rapidly grown the entire market at the forefront of wholesale and retail services as an effective solution to issues such as digital transformation and social distancing policy (COVID-19 pandemic). Small business owners, who form the majority at the center of the online shopping industry, are constantly collecting policy changes and market trend information to overcome these problems and use them for marketing and other sales activities in order to overcome these problems and continue to grow. Objective and refined information that is more closely related to the business is also needed. Therefore, in this paper, through the collection and analysis of big data information, which is the core technology of digital transformation, key variables are set in product classification, sales trends, consumer preferences, and review information of online shopping malls, and a method of using them for competitor comparison analysis and business sustainability evaluation has been prepared and we would like to propose it as a service. If small and medium-sized businesses can benchmark competitors or excellent businesses based on big data and identify market trends and consumer tendencies, they will clearly recognize their level and position in business and voluntarily strive to secure higher competitiveness. In addition, if the sustainable growth of the online shopping mall operator can be confirmed as an indicator, more efficient policy establishment and risk management can be expected because it has an improved measurement method.

Virtualization is a promising approach to consolidating multiple online services onto a smaller number of computing resources. A virtualized server environment allows computing resources to be shared among multiple performance isolated platforms called virtual machines. Through server virtualization software, applications servers are encapsulated into VMs, and deployed with APIs on top generalized pools of CPU and memory resources. Networking and security have been moved to a software abstraction layer that transformed computing, network virtualization. And it paves the way for enterprise to rapidly deploy networking and security for any application by creating the virtual network. Stochastic reward net (SRN) is an extension of stochastic Petri nets which provides compact modeling facilities for system analysis. In this paper, we develop SRN model of network virtualization based on virtual switch. Measures of interest such as switching delay and throughput are considered. These measures are expressed in terms of the expected values of reward rate functions for SRNs. Numerical results are obtained according to the virtual switch capacity and number of active VMs.

In most countries, public libraries have played a role as a hub of knowledge and information, complex culture of local communities, and a third place for meeting and communication. And recent public libraries are focusing on enhancing their core competencies and expanding services using digital technologies to meet the era of digital transformation and the 4th industrial revolution. However, after the COVID-19 pandemic occurred, all public libraries are repeatedly closed, reopened, and partially closed, and all resources are devoted to providing non-contact, digital and online alternative services, and are expected to continue in the future. As a result, future public libraries are bound to face a trilemma in which digital expandability, complex cultural space, and importance as a place of knowledge and information service are conflicting. This study discoursed on the public library trilemma in the post-COVID-19 era and suggested ways to overcome it. The orientation of the future public library is the fusion and harmony of multiplicity and multipurpose, place and space, knowledge & information and complex culture, face-to-face service and remote service. The main body of a public library is not the finger (digital and non-contact), but the moon (knowledge information center).

Recently, the development of information technology (IT) continues to promote the digitalization of archives (valuable records) and has therefore, affected archiving centers. This digitalization is shown to these archiving centers by taking advantages of various digital exhibitions. This study aims to consider why it is necessary to use digital exhibitions in archiving centers. In order to examine the needs of digital exhibitions, this study focuses on some ideas and important roles in digital exhibitions and research cases of online exhibitions applied with digital technology. Consequently, this study derives some values from them. Digital exhibitions held online continuously provide the following; first, a great amount of information about the archives by using hyperlink; second, the ability to recreate the attractive contents of digitalized archives by utilizing virtual reality, which makes the users greatly interested; the third and final thing online digital exhibitions provide is the storytelling it provides, which also serves as an avenue for people to communicate with one another. These processes of communication are also reflected in the story. In addition, they can help publicize not only the archiving center, but also the local community as it promotes cultural and tourism resources.

The purpose of this study is to examine the factors related to learning through analysis of domestic research trends in literacy and to present the direction of literacy education. Research papers from 1993 to February 2022 were collected using RISS. 'Literacy' and 'Education' were used as search keywords, and 200 papers were selected for analysis. As a result of analysis using keyword network analysis, 118 keywords appeared at least three times out of a total of 810 keywords. The order of the keywords with the highest frequency is 'digital literacy', 'media literacy', and 'elementary school'. The following direction was suggested through the analysis results. First, it is required to establish an online teaching and learning resource platform and link it with education policy. Second, it is necessary to set literacy competencies and seek ways to improve competencies. Third, a digital-based convergence education model should be developed. This study is meaningful in that it analyzed the most recent literacy studies and suggested the direction of literacy education.

In order to improve the quality of consumption in senior generation, it is necessary to build trust in the digital consumption environment. However, there are limitations from previous researches on consumption in the digital environment that has mainly focused on Millennial and Z generations. Therefore, this study aims to examine the antecedents of digital consumption trust and to explore the market segments of senior generation created by the dynamics of these antecedents. In addition, in order to provide practical implications, we investigate the difference in the level of perceived digital consumption trust using segmentation. This study, therefore, used 2021 Korea's consumer life index data conducted by the Korea Consumer Agency for general consumers, and only consumer data of 60s and older are extracted for the analysis. As a result, we confirm from the main results that the three antecedents, consumer competency, perceived corporate responsibility, and local community's problem-solving environment, are significant in building the digital consumption trust in the senior generation. It is academically significant in this aspect to look at approaches to improve senior customers' trust in digital consumption circumstances by dividing generations because generations exhibit varying levels of understanding of online consumption or digital consumption conditions. It is academically significant in this aspect to look at approaches to improve senior customers' trust in digital consumption circumstances by dividing generations because generations exhibit varying levels of understanding of online consumption or digital consumption conditions. Additionally, it is proposed as a practical implication that it should be managed so that significant improvements of customers, businesses, and regional public institutions are developed in order to allow the senior consumers to prepare trusted digital consumption circumstances.
