As online classes started in 2020 due to the COVID-19 outbreak, the use of online content in classes such as e-books, Google tools, and videos has increased. Accordingly, the need for textbooks made by teachers is emerging so that students can learn effectively even in an online environment. In addition, as online classes and student-participatory classes using various online contents expand, teachers are actively using online content-using textbooks as well as book-type textbooks. In other words, it is a time not only to prepare for online classes, but to establish the concept of online textbooks and to think about the system and direction of current textbooks in order to transform into a future education system. Therefore, in this paper, the basic data for establishing the concept of online content utilization textbooks that are currently being introduced have been analyzed and theoretical contents for the development direction of future textbooks to be developed in the future are explored.

In this paper, we propose an efficient dynamic workload balancing strategy which improves the performance of high-performance computing system. The key idea of this dynamic workload balancing strategy is to minimize execution time of each job and to maximize the system throughput by effectively using system resource such as CPU, memory. Also, this strategy dynamically allocates job by considering demanded memory size of executing job and workload status of each node. If an overload node occurs due to allocated job, the proposed scheme migrates job, executing in overload nodes, to another free nodes and reduces the waiting time and execution time of job by balancing workload of each node. Through simulation, we show that the proposed dynamic workload balancing strategy based on CPU, memory improves the performance of high-performance computing system compared to previous strategies.

2010년 이후 대학을 중심으로 앙트러프러너십 교육의 중요성이 강조되면서, 그동안 창업과 기업가정신 관련 프로그램이 양적으로 급격하게 증가하여 왔다. 또한, 부처들이 모여 '대학창업교육 5개년 계획'을 수립하고 추진하며 그 확산은 더욱 빠르게 진행되었다. 하지만 현실은, 앙트러프러너십 전문교수자의 부족, 창업인프라 편중현상으로 인한 교육혜택의 지역편차 심화, 천편일률적이고 파편적인 교육커리큘럼, 그리고 빠른 변화의 스타트업 환경과 속도를 따라잡지 못하는 대학 내부체계 등 앙트러프러너십 교육의 전반적인 문제점이 심각하게 거론되고 있는 상황이다. 이러한 문제들의 해결을 위한 하나의 방편으로 온라인플랫폼을 바탕으로 하는 앙트러프러너십 교육의 질적향상과 양적확산을 통해 문제를 해결하려는 움직임이 일어나고 있다. 이미 해외에서는 대중을 대상으로 온라인플랫폼을 통한 대규모공개수업 MOOC(이하 '무크')가 확산되고 활발히 연구되고 있다. 온라인플랫폼 기반의 앙트러프러너십 교육 또한 비즈니스 범주에서 주요한 위치에 자리를 잡고 있으며, 효과성에도 좋은 결과를 내며 진행되고 있다. 본 논문의 목적은 대규모 개방 온라인교육 수업과정인 무크에 대한 정확한 개념과 구조적 배경의 이해를 통해, 무크 현상의 본질적 가치와 의미를 발견하고 앙트러프러너십 교육에의 적용방법과 기대효과에 대한 고찰을 하였다. 목적한 연구의 진행을 위해 질적연구방법론을 사용하여 최신문헌 검토 및 참여관찰, 심층면담, 이해당사자 인터뷰를 진행하였고, 근거이론을 기반으로 핵심키워드를 도출하여 연구의 전체적인 맥락을 구성하였다.

In a situation where the online learning is expanding due to COVID-19, the current maker education has limitations in applying it to classes. This study is to design the class of online maker education using artificial intelligence tools in elementary school. Also, it is to identify the responses to it and to confirm whether it helps improve the learner's computational thinking and creative problem solving ability. The class was designed by the literature review and redesign of the curriculum. Using interveiw, the responses of instructor and learners were identified. Pre- and post-test using corresponding sample t-test was conducted. As a result, the class consisted of ten steps including empathizing, defining making problems, identifying the characteristics of material and tool, designing algorithms and coding using remixes, etc. For computing thinking and creative problem solving ability, statistically significant difference was found. This study has the significance that practical maker activities using educational artificial intelligence tools in the context of elementary education can be practically applied even in the online environment.

On-Line Lectures are becoming more common due to the MOOK service and the expansion of national policy in Korea. Especially, It is being changed to new remote mixed style from traditional lecture in universities. We propose and implement a remote contents making tool with audio synchronization function based on more with less resources. To implement our proposed algorithm, we design an interactive interface to assign multiple cutting intervals and convert an input video to print a new result. In experimental, we can confirm our algorithm works properly with average performance value 9.3% cpu share ratio and 87mega byte ram usage(CPU 2.60GHz, 820*600 Area).

Online design education, started with the establishment of cyber universities in Korea in 2001, has been operated with the development of online classes for various subjects until present and is predicted to be expanded both quantitatively and qualitatively as the concept of remote education is gradually generalized along with the growth of cyber universities and the development of digital technologies. However, regardless of such quantitative growth and possibility of development, the current online design classes are operating curriculum that is not much different from that of design department at the existing offline universities, while the concepts and roles of design and designer are changing according to the stream of digital times. Moreover, although complex elements are required to be considered since online design education is influenced by digital technological trend as being a form in which digital technology, contents, and design are all combined and advantages and features of online are required to be reflected to the maximum, the reality is different from what has been expected due to many circumstances. Online design education needs to be changed in accordance with the stream of digital times and new online design curriculum suitable for the current of future digital times and online environment are required to be developed and prepared at this moment. Accordingly, this research aims to look into the concepts and roles of design and designer changing in accordance with the stream of digital times by researching the existing literatures as well as the advantages and features of online class and to analyze the current state of curriculum of digital design and related departments at cyber universities in Korea to suggest an improvement direction of curriculum of online design class suitable for the future digital times.
