전자책이란 저작물의 내용을 디지털 데이터로 CD-ROM, DVD 등 기록매체 또는 저장장치에 수록, 유·무선 통신망을 통해 전용 단말기나 컴퓨터로 이용할 수 있는 출판물을 의미한다. 전자책은 다양한 형태로(HTML, PDF, XML) 제작돼 표준이 없어 별도의 단말기를 개발 보급해야하는 문제와 함께 전자책 산업의 중복투자를 발생시켜 활성화에 어려움을 겪어왔다. 2002년 산업자원부 기술표준원은 이러한 문제를 해결하기 위해 상호운용성 등이 뛰어난 XML에 기반한 전자책 문서 표준(EBKS 1.0)안을 국가표준으로 제정하였다. 교육인적자원부에서도 2002년 '교과용 도서에 관한 규정' 을 개정, 주교재와 보완교재의 구분을 폐지해 음반이나 영상, 전자저작물 등을 활용한 전자교과서 및 지도서를 제작할 수 있도록 했다. 이러한 시대흐름에 발맞추어 본 연구에서는 XML Schema를 활용한 중학교 컴퓨터 과목의 전자교과서 문서 표준을 개발해 보고자 한다. EBKS를 비롯한 기존 연구의 대부분은 XML DTD를 이용한 표준 개발이 중심이었으나 DTD가 가진 제한점들로 인해 이미 XML Schema의 사용이 권고되고 있다.

All around the world, numerous scientists have been carried out researches of e-Science to improve performance of computations and accessibility of their experimental flexibilities for a long times. However, they still have been in difficulty securing high-performance computing facilities. In case of Aerodynamics, for example, a single experiment costs a tremendous amount of budget and requires a span of more than 6 months even though researchers have been developed diverse improved mathematical methods as well as relied on advanced computing technologies to reduce runtime and costs. In this paper, we proposed a multiple infrastructure-based scientific workflow environments for engineering education in fields of design optimization of aircraft and demonstrated the superiority. Since it offers diverse kind of computing resources, it can offer elastic resources regardless of the number of tasks for experiments and limitations of spaces. Also, it can improve education efficiency by using this environment to engineering education.

This study examines the digital divide, one of the main issues in digital media environment, in relation with the digital literacy on the perspective of audience welfare. The study explores the current state of audience welfare policy with regard to the issue of digital divide which can be seen as the dark side of this flourishing digital technology society. The barriers and enablers of the digital divide are discussed with the question of how these factors are related with the digital literacy competence of audience. It has been criticized that both the research efforts and the policy implementations on the digital divide had been set within the limitation of physical access to the digital equipment and technology. Recent studies suggested that the digital divide should be viewed in dynamic interaction of a variety of factors such as psychological dispositions, inner attitudes toward digital media, competence and ability of audiences as well as socio-economic status of individuals. Despite the recent inclusive discussion, however, the role of digital literacy in the digital divide remains unexplored. It should be noted that the question of access is not just to do with equipment, but with skills and knowledge that are required to use equipment. This notion suggests an important implication for the digital divide policy establishment. This study proposes a two-stage solution for reducing the digital divide, in which the first stage focuses on physical access and technology education and the second stage on the digital literacy education.

Purpose: This study examines the weight control behavior depending on university students' motives of using social media. Methods: The participants were 447 university students in the Jeonbuk area. Collected data were analyzed using factor analysis, cluster analysis, analysis of variance, and χ² tests with SPSS v. 26.0. Considering the motives of using social media, we investigated the usage of social media, dietary behavior related to social media, and weight control behavior. Results: Using the K-clustering method, the motives to use social media were categorized into three clusters: cluster 1 was the interest-centered group, cluster 2 was the multipurpose information-seeking group, and cluster 3 was the relationship-centered group. Among the various social media sites, YouTube (86.8%), Instagram (76.1%), and Facebook (61.1%) were the most visited by the subjects. The dietary behavior related to social media in cluster 2 was significantly higher than clusters 1 and 3 (p < 0.001). Clusters 1 and 2 showed a significantly higher dissatisfaction with one's weight (p < 0.05) and consequent interest in weight control than cluster 3 (p < 0.001). Cluster 2 used weight control-related information from social media significantly more than other clusters (p < 0.05). Weight control experiences in cluster 1 and 2 were significantly higher than in cluster 3 (p < 0.001). Conclusion: Differences in dietary behavior related to social media and weight control behavior were observed between cluster types of motivation to use social media. Based on the usage motives of university students and their behaviors, we propose that educational programs should be conducted for weight control using social media.

In order to enhance instructional effects of multimedia contents, it is critical to emphasize the importance of interface and the affective aspects of learner characteristics in design processes. The main aim of this research was to assess the needs for evaluating icon design strategies on the basis of children's sensibilities by investigating differences between children and teachers in their sensibilities to the icons used in multimedia contents for elementary education. Some interesting findings were obtained from the research. Children had richer sensibilities to the icons presented in multimedia contents than teachers in terms of the average number of adjectives reflecting sensibilities. Among the children group, children living in urban areas showed richer sensibilities to the contents than those in rural areas. When the frequencies of the use of 5 adjectives commonly used by the two groups were compared, teachers showed positive sensibilities, but children demonstrated some negative sensibilities. Also children demonstrated richer sensibilities to certain contents than teachers. The results of the research indicated the need for evaluating icon design strategies on the basis of children's sensibilities in designing multimedia contents for children.

Web based instruction (WBI) has been widely used thesedays because the web has various advantages for instruction. However, most of current WBI systems do not support various requirements from students. It is because of the lack of research for structural instruction method. This paper presents a new method of WBI and designs an instruction model to support various requirements from students by implementing dynamic WBI system using JSP to solve current WBI problems. The developed WBI system uses multimedia based instructions. The implemented system focused on the practical instruction by providing the functions of listening, homework, and test on web site. For the similar effects as in the classroom, it supports functions of electronic white board and multimedia data which is consisted of high-quality sound and video data with high degree of compression. Furthermore, the system supports that instructors can design a test using three kinds of basic forms, a multiple-choice test, brief-answer test, essay test, and evaluate the tests easily. It also supports easy management for homework, lecture registration, and many school affairs.
