This study examines current trends and perceptions of veganism and vegan fashion in Korea, China, and the United States. Using big data tools Textom and Ucinet, we conducted cluster analysis between keywords. Further, frequency analysis using keyword extraction and CONCOR analysis obtained the following results. First, the nations' perceptions of veganism and vegan fashion differ significantly. Korea and the United States generally share a similar understanding of vegan fashion. Second, the industrial structures, such as products and businesses, impacted how Korea perceived veganism. Third, owing to its ongoing sociopolitical tensions, the United States views veganism as an ethical consumption method that ties into activism. In contrast, China views veganism as a healthy diet rather than a lifestyle and associates it with Buddhist vegetarianism. This perception is because of their religious history and culinary culture. Fundamentally, this study is meaningful for using big data to extract keywords related to vegan fashion in Korea, China, and the United States. This study deepens our understanding of vegan fashion by comparing perceptions across nations.

ChatGPT, a leader in generative AI, can use natural expressions like humans based on large-scale language models (LLM). The ability to grasp the context of the language and provide more specific answers by algorithms is excellent. It also has high-quality conversation capabilities that have significantly developed from past Chatbot services to the level of human conversation. In addition, it is expected to change the operation method of the tourism industry and improve the service by utilizing ChatGPT, a generative AI in the tourism sector. This study was conducted to explore ChatGPT trends and paradigms in tourism. The results of the study are as follows. First, keywords such as tourism, utilization, creation, technology, service, travel, holding, education, development, news, digital, future, and chatbot were widespread. Second, unlike other keywords, service, education, and Mokpo City data confirmed the results of a high degree of centrality. Third, due to CONCOR analysis, eight keyword clusters highly relevant to ChatGPT in the tourism sector emerged.

This study examines Korean users' attitudes and emotions toward Melon and Spotify, which lead the music streaming market. We used Text Mining, Semantic Network Analysis, TF-IDF, Centrality, CONCOR, and Word2Vec analysis. As a result of the study, MelOn was used in a user's daily life. Based on Melon's advantages of providing various contents, the advantage is judged to have considerable competitiveness beyond the limits of the streaming app. However, the MelOn users had negative emotions such as anger, repulsion, and pressure. On the contrary, in the case of Spotify, users were highly interested in the music content. In particular, interest in foreign music was high, and users were also interested in stock investment. In addition, positive emotions such as interest and pleasure were higher than MelOn users, which could be interpreted as providing attractive services to Korean users. While previous studies have mainly focused on technical or personal factors, this study focuses on consumer reactions (online reviews) according to corporate strategies, and this point is the differentiation from others.

Among eco-friendly energy, solar energy is one of the renewable energy sources that is developing in the spotlight in many countries. In line with this, the Korean government and local governments are carrying out projects to provide subsidies for the distribution of household solar power, raising the spread of household solar power and awareness. However, due to the lack of research on consumer perception of household solar power, this study investigated the perception of household solar power from 2015 to 2022 by setting the central word as solar power. As a result, 2016 had the highest number of collections, and when the top 50 words for each year were analyzed, it was confirmed that words related to the installation and maintenance of household solar power dominated. And through CONCOR analysis, a total of four were derived: solar energy recognition, renewable and eco-friendly energy recognition, solar government policies, solar companies, and perceptions of households. Through emotional analysis, it was confirmed that 2021 had the most positive data. As a result, consumer perception of household solar power is positive based on what was mentioned above, but research on how to use negative opinions on waste control and installation and maintenance should be conducted.

The purpose of this study is to analyze user perceptions of tourism platforms through big data. Data were collected from Naver, Daum, and Google as big data analysis channels. Using semantic network analysis with the keyword 'tourism platform,' a total of 29,265 words were collected. The collection period was set for two years, from August 31, 2021, to August 31, 2023. Keywords were analyzed for connected networks using TexTom and Ucinet programs for social network analysis. Keywords perceived by tourism platform users include 'travel,' 'diverse,' 'online,' 'service,' 'tourists,' 'reservation,' 'provision,' and 'region.' CONCOR analysis revealed four groups: 'platform information,' 'tourism information and products,' 'activation strategies for tourism platforms,' and 'tourism destination market.' This study aims to expand and activate services that meet the needs and preferences of users in the tourism field, as well as platforms tailored to the changing market, based on user perception, current status, and trend data on tourism platforms.

This study analyzes messages from Korean TV debates on the conflict over U.S. beef imports and the process of negotiations over the imports in 2008. The authors have conducted a content analysis and a semantic network analysis by using KrKwic and CONCOR. The data was drawn from nine TV debates aired by three major TV networks in Korea (MBC, KBS, and SBS) from 27 April 27 2008 to 6 July 2008. The results indicate substantial differences in the semantic structure between arguments by the government and those by civic groups. We also investigated the relationship between the terms frequently used by both sides (i.e., the government and civic groups), and the terms used exclusively by one side. There was a gradual increase in the number of terms frequently used by both sides over time, from the formation of the conflict to its escalation to its resolution. The results indicate the possibility of general agreement in conflict situations.

Since delivery food has become a new dietary culture, this study examines consumer awareness through big data analysis. We present the direction of delivery food for healthy eating culture and identify the current state of consumer awareness. Resources for big data analysis were mainly articles written by consumers on various websites; the collection period was divided into before and after COVID-19. Results of the big data analysis revealed that before COVID-19, delivery food was recognized as a limited product as a meal concept, but after COVID-19, it was recognized as a new shopping list and a new product for home parties. This study concludes by suggesting a new direction for healthy eating culture.

With the advent of the post-2020 climate regime, the hydrogen industry is growing rapidly around the world. In order to build the hydrogen economy, it is important to identify social issues related to hydrogen and prepare countermeasures for them. Accordingly, this study conducted a semantic network analysis on hydrogen news from NAVER. As a result of the analysis, the number of hydrogen news in 2020 increased by 4.5 times compared to 2016, and as of 2018, the hydrogen issue has shifted from an environmental aspect to an economic aspect. In addition, although the initial government-led hydrogen industry is expanding to the mobility field such as privately-led fuel cell electric vehicles and hydrogen fuel, terms showing concerns about the safety such as explosions are constantly being exposed. Thus, it is necessary not only to expand the hydrogen ecosystem through the participation of private companies, but also to promote hydrogen safety.

본 연구는 COVID-19 대유행에 의한 우울감과 공원 이용행태의 관계를 온라인상에 게시된 공원 이용에 대한 게시물을 이용하여 분석하고자 하였다. COVID-19 방역이 활발해진 기간 동안 네이버와 다음의 블로그 및 카페에서 '공원'과 '우울'을 포함한 텍스트 데이터를 수집하여 텍스트 마이닝(Text Mining)과 소셜 네트워크(Social Network)분석을 하였다. 연구결과, 우울감을 언급한 공원 이용자는 '보다', '산책/걷다', '먹다'의 이용행태를 주로 보였고, 소통 행태인 '보다'를 중심으로 다른 이용행태들이 연결되는 것으로 나타났다. CONCOR 분석 결과, 소통 행태 및 동적 행태의 군집의 경우, 단일 행태 유형으로 군집이 형성되어, 우울감을 언급한 이용자는 공원을 소통활동과 신체활동을 위한 공간으로 인식하는 경향이 나타났다. COVID-19의 대유행으로 소통활동과 신체활동의 결핍이 증가되었고 공원에서 이를 해소하려는 것으로 해석되었다. 또한 우울감의 발생으로 상대적으로 소극적인 이용행태가 주요한 이용행태로 나타났다. 본 연구결과는 도시민에게 효과적인 공원의 조성 및 관리 계획에 유용할 것으로 판단되었다. 후속 연구에서 COVID-19 대유행과 우울감의 유무를 연계한 공원 이용자의 이용행태 분석이 필요한 것으로 판단되었다.

본 연구의 목적은 2015 개정 중학교 기술·가정 교과서의 키워드를 분석하여 주생활 단원의 핵심개념과 내용구성을 파악하는 것이다. TEXTOM 프로그램으로 교과서의 단어 빈도분석과 네트워크 분석을 실시하였고, UCINET 프로그램으로 중심성과 CONCOR 분석을 하였다. 분석결과는 다음과 같다. 첫째, 주생활 단원의 내용 체계는 '가정생활과 안전' 영역의 '생활문화'와 '안전'으로 구분되어 있다. 둘째, '안전' 단원에서는 실내, 발생, 사용, 소음, 안전사고 순으로 출현빈도가 높으며, 주생활과 안전사고, 예방과 관련된 단어들이 서로 밀접하게 연결되어 있다. '생활문화' 단원은 공간, 주거, 가족, 사용, 주거공간 순으로 출현빈도가 높으며, 키워드 간 연관성도 높게 나타났다. 셋째, '안전' 단원은 실내, 발생, 사용 등이, '생활문화' 단원은 공간, 가족, 주거 등이 영향력 있는 핵심개념으로 나타났다. 넷째, '안전' 단원은 '안전한 주생활', '쾌적한 주거환경'으로, '생활문화' 단원은 '주거공간 구성', '공간 활용', '주거가치관과 생활양식', '주생활 문화'로 구성되어 있다. 이와 같은 결과를 통해 향후 주생활 교육의 방향성과 정체성을 형성하기 위한 기초자료를 제공한다는 점에서 본 연구의 의의가 있다.
