As digital education progresses, MOOC (Massive Open Online Courses) are increasingly utilized by learners, making research on MOOC learning outcomes a necessary endeavor. In this study, we systematically investigated the impact of audiovisual elements on learning outcomes in MOOC, highlighting the nuanced role these components play in enhancing educational effectiveness. Through a comprehensive survey and rigorous analysis involving descriptive statistics, reliability metrics, and regression techniques, we quantified the influence of text, graphics, color, teacher images, sound effects, background music, and teacher's voice on learner attention, cognitive load, and satisfaction. We discovered that background music and text layout significantly improve engagement and reduce cognitive burden, underscoring their pivotal role in the instructional design of MOOC. We findings contribute new insights to the field of digital education, emphasizing the critical importance of integrating audiovisual elements thoughtfully to foster better learning environments and outcomes. Not only advances academic understanding of multimedia learning impacts but also offers practical guidance for educators and course designers seeking to enhance the efficacy of MOOC.

Reviewing the outcomes of studies on contemporary information science during some periods and identifying the research area exposed in its studies are essential processes to develop the research and theories of information science and to establish the academic identity of information science. This study seeks to provide the some useful methodological approaches for establishing the research area of information science. The methodological approaches to research area of information science are as follows : (1) normative approach by concepts, definitions, and principles of information science, (2) content analysis of text books, (3) content analysis of curricula of graduate courses, (4) content analysis of graduate disserations or treatises, (5) IIS(Institute of Information Scientists)'s criteria for information science, (6) professors' need assessment, (7) interdisciplinary approach, etc. These are the representative types of methodological approach and have an enough validity and effectiveness in their own way. Therefore I think of that those should be integrately applied to establishing the academic identity of information science.

The purpose of this study was to establish a Korean reading ability assessment category based on a reading comprehension theory, and to establish an evaluation framework for Korean reading ability after creating the evaluation factors corresponding to each category through expert Delphi survey. The three levels of reading comprehension that were constructed are the following: language knowledge, text comprehension, and interpretation and comprehension of new ideas and application. This study suggested that constructs of Korean reading assessment reflected reading theory. This study has meaningful consequences which suggest verified constructs through Delphi surveys.

There is a growing interest in convergence. National R & D is also providing various policies and institutional support to promote convergence research. Convergence research, however, does not clearly specify its characteristics at the academic and government levels. This research proceeds with the process of collecting, refining, analyzing, modeling, verifying and visualizing national R & D data through the National Science and Technology Information Service (NTIS). The method is to derive the convergence research characteristics and to derive through text mining, focusing on the unstructured information of national R & D project data. The study confirmed that there was a difference in perception between the definition of converged research and the research site. In order to improve this, the research suggested that convergence among research subjects, collaboration among research topics reflecting various backgrounds and characteristics of researchers, and analysis of characteristics of convergence research using information were suggested in the process of establishing convergence policy.

Purpose - This study investigates research trends by searching for English keywords and abstracts in 1,511 Korean journal articles in the Korea Citation Index from the 2002-2019 period using the term "Port." The study aims to lay the foundation for a more balanced development of port research. Design/methodology - Using abstract and keyword data, we perform frequency analysis and word embedding (Word2vec). A t-SNE plot shows the main keywords extracted using the TextRank algorithm. To analyze which words were used in what context in our two nine-year subperiods (2002-2010 and 2010-2019), we use Scattertext and scaled F-scores. Findings - First, during the 18-year study period, port research has developed through the convergence of diverse academic fields, covering 102 subject areas and 219 journals. Second, our frequency analysis of 4,431 keywords in 1,511 papers shows that the words "Port" (60 times), "Port Competitiveness" (33 times), and "Port Authority" (29 times), among others, are attractive to most researchers. Third, a word embedding analysis identifies the words highly correlated with the top eight keywords and visually shows four different subject clusters in a t-SNE plot. Fourth, we use Scattertext to compare words used in the two research sub-periods. Originality/value - This study is the first to apply abstract and keyword analysis and various text mining techniques to Korean journal articles in port research and thus has important implications. Further in-depth studies should collect a greater variety of textual data and analyze and compare port studies from different countries.

Objectives :The Shishimilu is a clinical treatise, published in 1687 by Qing period doctor, Chensiduo. The purpose of this study is to report the newly discovered Korean translation to the academic world and discuss its significance. Methods : The newly discovered Korean translated version was examined in detail focusing on bibliography and content items. In addition, the time of introduction of the Shishimilu to Joseon was studied philologically. Results : 1. The time of completion was during the period of the Korean Empire. 2. The original text was faithfully translated. 3. The book was rearranged from the original document to make it easier to apply in clinical practice. 4. Experiences of Joseon medicine were reflected, mainly prescriptions. 5. According to documentary evidence, the Shishimilu was first introduced to Korea only in the late 19th century, and was widely distributed during the Japanese colonial period. Conclusions : he Korean translated version of the Shishimilu was the earliest among known Korean translations of Chinese medical texts, and while faithfully translating the original text, the compilation was rearranged to make it easier to apply clinically. In addition, the experience of Joseon medicine was reflected mostly in prescriptions. It could be determined that if contents of the Shishimilu appear in Korean literature whose writing period is unknown, it can be historically verified to have been written after the late 19th century.

This study is the academic work to explore the potential meanings of print advertisements. Linguistic features such as repetition, variation, contrast and phonological structure in the verbal texts of ads can give rise to shades-of-meaning or slight variations in advertising. The language of advertising is not only language in words. It is also a language in images, colors, and pictures. Pictures and words combine to form the advertisement's visual text.. While the words are very important in delivering the sales message, the visual text cannot be ignored in advertisements. Forming part of the visual text is the paralanguage of the ad. Paralanguage is the meaningful behaviour accompanying language, such as voice quality, gestures, facial expressions and touch in speech, and choice of typeface and letter sizes in writing. Foregrounding is the throwing into relief of the linguistic sign against the background of the norms of ordinary language. This paper focuses its discussion on the advertisements within the framework of the paradigmatic and the syntagmatic relationship. The sources of ads have been confined to Malboro. The ads were reselected based on purposive sampling methods.

This study is aiming to structure progressive instructional strategy for development of constructivist-thinking into the beginning stage, developmental stage, and advanced stage, then organize multiple choice, completion, descriptive, and essay problems to be suitable for each stage of the strategy, and finally, to evaluate what effects this instructional strategy has on the students' academic achievements and enhancement of their scientific essay writing skills. The results of the study are as follows. First, lessons applying the strategy for developing constructivist-thinking were more effective in enhancing student' academic achievement than the text book-oriented lecture type lessons. In changes in academic achievement, the test group, for both high and low levels, displayed a higher average than the control group, however, changes in the high level was not statistically significant and changes in the low level students were found to be statistically significant. Second, scientific essay writing skills were found to be effective in all levels of the test group and the averages in both high and low groups of the test group were higher than those of the control group and were also found to be statistically significant.
