Due to rapid internet supply, the increase of electronic resources including network resources, and the appearance of metadate, there has been a sudden change in cataloguing fields. To deal with rapid changes, the related organizations such as IFLA are organizing the research team and revising rules. This study analyzes current trend of cataloguing digital resources, considering recent matters in regards with the revision of ISBD(ER), AACR2R 2002 edition, MARC 21, Dubin Core, KCR4 etc. This research discusses also the questions of how digital resources are organized; automatic indexing, matadata, and MARC format.

Recently, the central government organizations have changed their Business Management System to the cloud-based On-nara Document 2.0. According to this, the National Archives of Korea is spreading a cloud-based records management system. With the development of digital technology, including cloud computing, preservation and utilization of records must be redesigned continuously to be effective and efficient. It is needed that the process and method of the electronic records management will change from simple digitization of paper-based recording to digital technology. This article offers opinions related to the logical transfer, storage and redundancy elimination of digital objects, machine-readable format, big-data analysis, templates of official documents, and authenticity authentication system based on universally unique identifiers (UUID) and hash value.

The purpose of this study was to investigate high school students' competencies of creativity thinking, critical thinking, communication, collaboration, and digital competence by implementing science fiction STEAM program. Based on the story of 'Fritz Haber' and the 'Garden of Dawn', a STEAM program was developed according to the ADDIE model. In the analysis stage, the purpose of the teaching-learning program using novels was set, and learners and learning environments were analyzed. At the design stage, the novels 'Fritz Harbor' and 'Garden of Dawn' were selected, learning goals were set according to the achievement standards of the curriculum, and learning contents and learning activities were sequenced and designed. In the development stage, teaching and learning materials were developed in a module format, implemented to classes, and evaluated. Pre-test and post-tests were conducted to identify the five major competencies such as creativity thinking, critical thinking, communication, collaboration, digital competence. The collected data was verified by paired t-test using SPSS. The results of the study showed statistically significant results in creative thinking, critical thinking, and digital competency.

After the pandemic, the world has brought about a society that connects to digital content faster. In the performing arts world, technology is also changing the production environment, content, and format of works. In addition, theatre and performances linked to digital media and virtual reality continue to be actively developed and increased. This paper first diagnoses how theater and acting education are meeting consumers(students) in a time when these changes progress rapidly. In the post-COVID-19 era, a crack began in the traditional method of education. We look at the existing problems of traditional education of theatre and acting in detail and look at the points of change from the changes in the virtual world and digital media environment. In conclusion, post-pandemic theater and acting education needs to shift to a consumer-centered paradigm.

The continuous increase in urban population due to migration of mases from rural areas to big cities has set urban water supply under serious stress. Urban water resources face scarcity of available water quantity, which ultimately effects the water supply. It is high time to address this challenging problem by taking appropriate measures for the improvement of water utility services linked with better understanding of demand side management (DSM), which leads to an effective state of water supply governance. We propose a dynamic framework for preventive DSM that results in optimization of water resource management. This paper uses Agent Based Modeling (ABM) with Digital Twin (DT) to model water consumption behavior of a population and consequently forecast water demand. DT creates a digital clone of the system using physical model, sensors, and data analytics to integrate multi-physical quantities. By doing so, the proposed model replicates the physical settings to perform the remote monitoring and controlling jobs on the digital format, whilst offering support in decision making to the relevant authorities.

The advances in communication technology and the popularity of network have rendered the increment of demand and desire to digital contents, and a number of creative digital contents produced. According to the time of compilation and a production of raw data, and manners, the format of digital contents may be variable and there can be existed in many connection information about digital contents. Although there are many metadata for standardizing the digital contents, they do not consider for expressing the connection relation about digital contents. In this paper, we proposed the new metadata for expressing the connection information about digital contents. This metadata is compatible the metadata of dublin core out of international standard of digital contents. Our metadata can express the variable direct or indirect connection relation about digital contents by expanding the relation element of dublin core. Also, our system can provide more useful information since we develop a system for managing connection information of digital contents based on our metadata.

In this paper, we design and implement remote servo motor control system with real-time micro embedded operating system. The system, where controller and camera image grabber are mounted, handles control commands transmitted from a remote PC web browser. A hard real-time servo motor driver running on the real-time micro embedded OS and then a digital control application which confirms precise sampling time intervals is constructed. Frame grabber images transmitted from camera are saved in a image data format to view on remote PC web browser.

PDF(Portable Document Format)와 XML(eXtensible Markup Language). 전자문서의 표준으로 서로 다른 방법론을 갖고 출발한 양 진영의 대결은 여전히 계속되고 있다. 최근 한국어도비시스템즈는 더욱 강력하고 새로운 기능들로 무장한 '애크로뱃(Acrobat)6.0'을 발표하면서 전자문서 시장에 대한 공세를 강화하고 있다. 이에 질세라 XML 진영에서는 ebXML, 로제타넷 등 XML 기반 응용솔루션에 대한 개발 및 영업에 더욱 박차를 가함으로써 부가가치 높이기에 적극적이다.

In this paper, we proposed a system for bit stream wireless communication using audio/video infrared transceiver and implemented a circuit. The proposed transmitter system converted bit stream into analog signal format that is similar to NTSC. Then the analog signal can be transmitted by infrared spatial coupler for A/V signals. And the receiver system recover the bit stream by inverse process of transmitter.
