As 49% of the world's population uses social media platforms, communication and content sharing within social media are becoming more active than ever. In this environmental base, the one-person media market grew rapidly and formed public opinion, creating a new trend called sell-sumer. This study defined new types of influencers by product category by analyzing the subject concentration of the commercial/non-commercial keywords of influencers and the impact of the ratio of commercial postings on sales. It is hoped that influencers working within social media will be helpful to new sales strategies that are transformed into sell-sumers. The method of this study classifies influencers' commercial/non-commercial posts using Python, performs text mining using KoNLPy, and calculates similarity between FastText-based words. As a result, it has been confirmed that the higher the keyword theme concentration of the influencer's commercial posting, the higher the sales. In addition, it was confirmed through the cluster analysis that the influencer types for each product category were classified into four types and that there was a significant difference between groups according to sales. In other words, the implications of this study may suggest empirical solutions of social media sales strategies for influencers working on social media and marketers who want to use them as marketing tools.

is a project for the senior generation with humanistic knowledge to become a mentor and communicate with them to present the wisdom and direction of life to the new generations of mentees based on various life experiences. has been expanding since 2015, starting with the pilot operation in 2014. In general, projects such as these are assessed to establish effectiveness indicators to verify effectiveness and to establish project management and development strategies. However, most of the evaluations have been conducted quantitatively and qualitatively based on the short-term duration of the project. Therefore, in the case of continuous projects such as , especially in the field of culture and arts where long-term effectiveness verification is required, the short-term evaluation is difficult to predict and judge the actual meaningful effects. In this regard, tried to examine the qualitative change of key participants in this project through the 2017 and 2018 image tracking survey. For this purpose, we adopted qualitative research methodology through interview video shooting, field shooting, and value coding as a research method suitable for the research subject. To analyze the results, first, the interview images were transcribed, keywords were extracted, value encoding works were matched with human psychological values, and the theoretical method was used to identify changes and to derive the meaning. In fact, despite the fact that the study conducted in this study was a follow-up survey, it remained a limitation that it analyzed the changed pattern in a rather short time of 2 years. However, this study systemized the specific methodology that researchers should conduct for follow-up and provided the flow of research at the present time when there is hardly a model for follow-up in the field of culture and arts education business in Korea as well as abroad. Significance can be derived from this point. In addition, it can be said that it has great significance in preparing the detailed system and case of comparative analysis methodology through value coding.

This study attempted to identify the life and death reproduced in literary works and present well-aging and well-dying using literary studies that considered Korean literature. Literary works such as poems, novels, and plays recorded between the 13th and 20th centuries covered in 10 literary studies in this study were investigated and analyzed. The survey methods include general and outline sections, literary genre sections, period sections, and keyword review. As a result of the analysis, most of the literature studies corresponded to details including author theory. They were concentrated on the novel and poem, and mainly dealt with 20th century literary works. In addition, the relationship between death, life patterns, well-dying, and well-aging inherent in literary works was identified. It was the concept of a whole set and a subset. In conclusion, this study has a limitation in studying literary works at a specific period. Nevertheless, we examined the nature of well-aging in life as a hope to secure a prospect from Korean literature. And this study recognized the nature of well-dying in death and meaningful death as a rite of passage derived from Korean literature. In the future, it is expected to contribute to the realization of well-dying, well-aging, and application of convergence research in Korean society in the 21st century.

In the light of the researchers' recognition towards the designs of tellers and listeners in storytelling classes, the purpose of this study was to analyze a research trend in Korean Education in which storytelling had been utilized and to suggest a proper direction in the related education and research. The most essential thing in the conceptualization towards storytelling was thought to be 'intercommunication.' Also, it is considered as the most basic conceptual factor who we would regard as 'tellers' and 'listeners' in order to plan and construct Korean language classes. Based on this understanding, this study searched and analyzed total 28 research results, which had been published from 2008 to 2021(May), through an academic searching site, Riss with the keyword "Korean Education Storytelling." The analysis exhibited that the formation of Korean classes utilizing storytelling originated from three kinds of researchers' previous conceptualization towards storytelling.: Writers' storytelling, teachers' storytelling, and learners' storytelling. Among them, the most large portion was devoted to 'leaners' storytelling'; its subcategories were learners' retelling, interpretative storytelling, learners' negotiated storytelling and learners' creative storytelling. This study, according to the classification on conceptualization of storytelling above, categorized the results and discussed the characteristics of each subcategory and their educational implications respectively.
