The cyber university, which authoring systems for digital contents using multimedia technologies ate used for its courses, is highlighted to be a promising alternative for the current off-line education system. As the demand for the authoring system is constantly increasing, many systems, which emphasize the developers' convenience only, are currently used. Since the generated digital contents using these systems are failed to draw the learners' active interaction with contents, the new authoring system is expected to be existed. This paper presents, develops, and implements the new contents authoring system by using programing languages and/or software tools based on the storyboard. The presented, developed, and implemented system mimics the face-to-face education in off-line system, induces the users' active interaction with contents, and the effective evaluation system to the users.

This survey is performed to propose the direction of policy development on reading education for Jeollabukdo Office of Education. To do this, this survey asked 239 teachers who are in charge of each school's reading education. The questionnaire is designed to investigate the effectiveness of current support projects from Jeollabukdo Office of Education, current level of schools' reading education and priorities of policy development. The findings of this survey are as follows: The teachers are contented with current support projects. Each school provides an average of 4 reading programs per year. Elementary schools' level of reading education is higher than middle and high schools' level. And more employment of full time reading experts as teacher librarian and the improvement of school libraries are revealed to be more important priorities on the policy development of reading education. Based on these findings, this study proposed maintenance of current support projects, improvement of school libraries, development of specialized policies for elementary schools, enhancement of reading teachers' expertise and preparation of information sharing system as the direction of policy development.

The types of information literacy in school library is classified into usage instruction of school library, reading education, instructional development o4 courseware with school library and integrated instruction of collaboration with school librarian and teacher. A measure of scholastic achievement on information literacy varies in each school. The cause is rely on the absence of librarians who teach information literacy and lack of understanding on the role of school library in information literacy. Nevertheless, we know that the program based on subject teacher is successful in terms of the effectiveness of the program. It demonstrate that if information literacy will be considered as important course in the curriculum for school librarian, the effectiveness of information literacy can be enhanced dramatically. For the purpose some strategies are required. In this paper, propose three strategies, which are integration of information literacy into curriculum of schools, analysis of the curriculums and a practical method for training school librarian.

The authoring systems for digital contents using multimedia technologies ate requested in many fields such as education, medical science, entertainment market e-commerce and etc. Especially, the emergence of cyber universities and the rapid expansion of on-line education market require the effective contents authoring systems, which have various functions to generate the qualified contents. Therefore, many systems arc developed and currently used. However, since the developed systems considered only the developer's convenience, the generated digital contents by using these systems are failed to draw tile users'(or learners') active interaction with contents. That is, since the users just watch the contents like watching a drama or a film, it causes many problems in delivering the contents effectively or in evaluating the users. This paper presents, develops, and implements the new contents authoring system by using programing languages and/or software tools. The presented, developed, and implemented system mimics the face-to-face education in off-line system, induces the users' active interaction with contents, and continuous evaluation to the users.

Concerns related to diversity are important throughout society, especially in the context of expansive globalization. In education, diversity-related issues require careful consideration to ensure social groups that have historically been marginalized benefit from educational opportunities. In this study, we investigated a case from within the United States aimed at addressing diversity issues in schools and discuss the implications of this study in relation to diversity issues in Korea. More specifically, we examined the features of the professional development program designed and implemented by the Smithsonian Science Education Center, as well as survey results from teachers who participated between 2019-2020. Our findings revealed that the program provided participants context specific experiences, space and time to develop an in-depth understandings of the causes of diversity issues and supports to attend to the various perspectives needed to set specific goals and action plans and to examine, refine, and revise their plans. Further, features of the professional development program had meaningful effects on participants' learning experience as they were supported to identify useful proposals and take action to solve their specific diversity issues. The findings from this study offer important implications for designing professional development and organizing supports to address varied current and future diversity issues in Korean school contexts.

A convergence study was conducted to identify effect size, intervention characteristics, and tendency of laughter therapies on depression for Korean older adults. Of the 486 studies searched in 10 databases, 20 studies in the inclusion criteria were selected. The risk of bias was assessed by SIGN's tool, and the data were analyzed using CMA 3.0 software. Overall effect size of laughter therapy on depression of older adults was medium (standardized mean difference [SMD]=-0.57, 95% CI: -0.70~-0.44, p<.001), and heterogeneity was small ($I^2=18%$). Subgroup analysis showed that the effect sizes of institutionalized group, mixed group, 4-6 weeks of duration, and group intervention were higher than the compared groups. Findings of this convergent meta-analysis would be helpful for health professionals to provide more effective laugher therapy sessions. Further replicative studies in long-term care facilities and more randomized controlled trials of laughter therapy are needed.

Turbulent flows around two-dimensional wing sections in ground effect are analysed by incompressible RANS equations and a finite difference method. The Baldwin-Lomax algebraic turbulence model is used to simulate high Reynolds number flows. The main purpose of this study is to clarify the two-dimensional ground effect and its flow characteristics due to different ground boundary conditions, i.e., moving and fixed bottom boundary. As a first step, to validate the present numerical code, the computational result of Clark-Y(t/C 11.7%) is compared with published numerical results and experimental data. Then, NACA4412 section in ground effect is calculated for various ground clearances with two bottom boundary conditions. According to the computational results, the difference in the lift and moment simulated with the two bottom boundary conditions is negligible, but the drag force simulated by the fixed bottom is to some extent smaller than that by the moving bottom. Therefore, it can be concluded that the drag force measured in a wind tunnel with the fixed bottom could be smaller than that with the moving bottom.

The purpose of this study is to verify the moderating effect of the social support (emotional support, informational support, material support, and appraisal support) on the effect of depression of middle-aged women on internet addiction. The 509 samples were selected through an online survey, and the collected data were conducted using the SPSS WIN26.0 program for frequency analysis, descriptive statistics, correlation analysis, and hierarchical regression analysis. As a result of the analysis, depression had a static effect on Internet addiction. Informational support and material support, among the four sub-factors of social support served as a moderator variable in the relationship between depression and Internet addiction. Based on the results, the followings were proposed; It emphasizes differentiated welfare services and interdisciplinary convergence research that are suitable for middle-aged women's characteristics, and suggests the necessity of internet addiction prevention education such as proper usage habits for internet use.
