It is required that university students acquire information technology in order to adapt to the information society. Therefore, it is inevitable for universities to provide students with an effective curriculum to improve IT fluency. The purpose of this study is to analyze the content of the informatics learning programs in universities in Korea in terms of IT fluency which is defined by National Academy of Science NRC99. Based on the information that the Academy Information Center announced, the content analysis was carried out from September 2010 to June 2011. According to the result of the analysis, 84 of 201 universities provide the informatics education as a mandatory course. 29 of them mainly provide the programs about word processors, spreadsheet, and presentation that are regarded as contemporary skills. These programs cover the fundamental concept, but the contents which require intellectual capabilities are rarely addressed. Moreover, the informatics education has mainly focused on elementary and secondary education. In this sense, it is valid to analyze the contents and current states of the informatics learning programs required in higher education.

In creative society, fluency in technology means the ability to reformulate knowledge, to express oneself creatively and appropriately, to produce and generate information in computer environment. Fluency in technology is essential for mathematics education with a point of constructivist view. In this paper, we study the meaning of fluency in technology, related to mathematics education. For this purpose, we suggest Papert's constructionism as a theoretical background and consider the principle of 'Learning through design' for fluency in technology. And we consider some principles for designing a mathematical microworld and implement a mathematical microworld for fluency in technology. With this microworld, we consider the after-school-program where students have participated a design activity.

The domestic content market has grown continuously. Furthermore, content consumption has rapidly increased in the COVID-19 era. For these reasons, it is necessary to investigate consumer behavior related to content business. This study focuses on content names as a key factor that induces consumers' interest in the content. In particular, this research examines if the conceptual fluency of the content name affects consumers' liking for the content. In addition, it explores the moderating effect of style of information processing (verbalizer vs. visualizer). The results of an experiment shows that the conceptual fluency on the content name is positively influential for liking content. Also, there was a significant interaction effect between verbalizers and conceptual fluency on content name. This study has important findings in terms of content marketing strategies. Above all, it has strong points because this research examines the style of information processing as an important consumer characteristic variable.

In the knowledge based society, it is very important to have an ability to solve problem with knowledge and information. In addition, the number of problems that can not be solved only with existing knowledge are increasing. Therefore, we developed an informatics education program that enhances creative problem solving abilities through systematic collection of information. This program designed to enhance both divergent thinking and convergent thinking. The developed program improves the problem solving ability with learner's internal knowledge as well as new information that is collected from external world. More practical and effective program can be provided through continuous program improvement.

This research aims to develop high-quality generative AI services by overcoming the limitations of existing Retrieval-Augmented Generation (RAG) models and implementing an enhanced graph-based RAG system to improve knowledge-based question answering (QA) systems. While traditional RAG models demonstrate high accuracy and fluency by utilizing retrieved information, their accuracy can be compromised due to the use of pre-loaded knowledge without rework. Additionally, the inability to incorporate real-time data after the RAG configuration leads to a lack of contextual understanding and potential biased information. To address these limitations, this study implements an enhanced RAG system utilizing graph technology. This system is designed to efficiently search and utilize information. In particular, LangGraph is employed to evaluate the reliability of retrieved information and to generate more accurate and improved answers by integrating various information. Furthermore, the specific operation method, key implementation steps, and case studies are presented with implementation code and verification results to enhance understanding of Advanced RAG technology. This research provides practical guidelines for actively implementing enterprise services utilizing Advanced RAG, making it significant.

The STEAM education and the computer science education have become increasingly important with the advert of science technology that enhances the national competitiveness. The purpose of the research is to develop the STEAM education program focused on programming education. I introduced a programming activity utilizing a sensor that can trigger students' interest with relation to other school subject factors. I applied the education program to grade 4-5 students, then compared and analyzed effects of the education program by conducting pretest and posttest regarding the creativity, reasoning skills, and the affective domain in science learning. Overall, the analysis reveals that the STEAM education program developed in this study improved fluency, originality and creativity index of the students' creativity, reasoning skills and scientific attitudes.

Digital citizenship includes an evolving set of knowledge and skills related to effectively and ethically using technology, especially when interacting with other people, information, and media in the online context. As public libraries have long provided access to and training with a variety of technologies, this study explores how digital citizenship has been covered in public library programming to identify potential trends and best practices. A purposive sampling of public library recipients of the American Library Association (ALA) and Information Today Inc.'s Library of the Future Award over the past 11 years (2013-2023) identified 7 case libraries to review. The titles and descriptions of 337 relevant library programs for audiences of school-aged children (5 years old and up) to seniors were collected for a 2-month period from each library's website and analyzed using Ribble & Parks (2019) 9 elements of digital citizenship. The findings suggest that programming related to digital citizenship most often addresses themes connected to digital access and digital fluency through coverage of topics related to computer and technology use. Based on themes and examples from the findings, public libraries are encouraged to expand upon existing programs to integrate all elements of digital citizenship, strive for inclusive and accessible digital citizenship education for all ages, and leverage resources and expertise from relevant stakeholders and community partnerships.
