  • This study recognizes that there is a correlation between the movement of the financial market and the sentimental changes of the public participating directly or indirectly in the market, and applies the relationship to investment strategies for stock market. The concerns that market participants have about the economy can be transformed to the search terms that internet users query on search engines, and search volume of a specific term over time can be understood as the economic trend of big data. Under the hypothesis that the time when the economic concerns start increasing precedes the decline in the stock market price and vice versa, this study proposes three investment strategies using casuality between price of domestic stock market and search volume from Naver trends, and verifies the hypothesis. The computational results illustrate the potential that combining extensive behavioral data sets offers for a better understanding of collective human behavior in domestic stock market.

  • This study relates to develop a quantitative method through which promising technology-based business items can be discovered and selected. For this study, we utilized patent trend analysis, technology-industry concordance analysis, and keyword co-occurrence analysis of US patents. By analyzing patent trends and technology-industry concordance, we were able to find out the emerging industry trends : prevalence of bio industry, service industry, and B2C business. From the direct and co-occurrence analysis of newly discovered patent keywords in the year, 2000, 28 promising business item candidates were extracted. Finally, the promising item candidates were prioritized using 4 business attractiveness determinants; market size, product life cycle, degree of the technological innovation, and coincidence with the industry trends. This result implicates that reliable discovery and selection of promising technology-based business items can be performed by a quantitative, objective and low- cost process using knowledge discovery method from patent database instead of peer review.

  • Since the third artificial intelligence boom was triggered by deep learning, it has been 10 years. It is time to analyze and discuss the research trends of deep learning for the stable development of AI. In this regard, this study systematically analyzes the trends of research on deep learning over the past 10 years. We collected research literature on deep learning and performed LDA based topic modeling analysis. We analyzed trends by topic over 10 years. We have also identified differences among the major research countries, China, the United States, South Korea, and United Kingdom. The results of this study will provide insights into research direction on deep learning in the future, and provide implications for the stable development strategy of deep learning.

  • The circumstances of overseas construction market is developing into quite complicated and diversified trends. Construction circumstance is escaping from localization to the open competitions, and from developing countries focused to the resources developing countries. Thus, new strategies for order competitiveness improvement based on our know-hows are required to secure the order volumes. This study has analyzed domestic construction companies' order trends in overseas construction market, and proposed strategic plans through analyzing of Order Causes on overseas construction projects to improve the order competitiveness.

  • Educational technology (ET) and learning sciences (LS) are two related disciplines that have shared interests in studying technologies for advancing human learning. This study conducted a content analysis of articles published in authoritative academic journals, Educational Technology Research and Development (ETR&D) and Journal of the Learning Sciences (JLS) from 2003 to 2012. By selecting and examining 93 issues with 429 articles during this decade with three analytical frameworks, the purpose of this study is to determine research trends precisely and create a scientific communication and theoretical connections for these two disciplines. The illustrated results indicate the dialogue between these two communities has begun yet accompanied by some certain limitations, whereas, they still need be more cooperative and communicational to move towards further integration, so as to contribute to promoting progressive education, learning theory and practice.

  • The purpose of this study is to analyze the research trends in articles on parenting stress published in Korean academic journals. Between 1996 and 2010, 116 articles on parenting stress were published in 16 reliable journals in Korea. This study analyzed research frequency, contents and methodology. Results show that the number of studies has increased during the years. Most studies used methods categorized as quantitative data and cross-sectional surveys. The most frequently used measurement scale was Abidin's Parenting Stress Index. Many were analyze by using regression. The main content of these studies were the factor related to parenting stresses and the relationship between the factors and parenting stress.

  • This study starts with the premise that many problematic situations in modern society can seriously damage personal feelings and that this phenomenon can create anxiety in individuals and society. In order to address such anxiety in individuals and society, we would like to propose measures to heal emotions. Accordingly, 270 research trends related to emotions studied from 2005 to 2020 will be analyzed to establish the direction of future research on emotion healing. As a result of analyzing the trends of healing papers, active healing studies have been conducted since 2010, but reading and writing healing through specific academic societies has been the main focus. Theoretical research accounted for a large portion, and emotional research was steadily conducted. Although healing methods are expanding to various topics, they have not been commercialized as specific methods. As a result, we hope that concrete research to heal individual emotions will be expanded and measures to implement a stable future society will be proposed.

  • Purpose - This study aims to find clues necessary for the direction of leadership development suitable for the current situation by exploring the direction in which leadership has been studied from the perspective of domestic researchers, along with the arrangement of leadership theories studied in various ways. Research design, data, and methodology - A total of 7,425 papers were obtained due to the search, and 5,810 papers with English abstracts were used for analysis. For analysis, word frequency analysis, word clouding, and co-occurrence were confirmed using Python 3.7. In addition, after classifying topics related to research trends through BERTopic and LDA, trends were identified through dynamic topic modeling and OLS regression analysis. Result - As a result of the BERTopic, 14 topics such as 'Leadership management and performance' and 'Sports leadership' were derived. As a result of conducting LDA on 1,976 outliers, five topics were derived. As a result of trend analysis on topics by year, it was confirmed that five topics, such as 'military police leadership' received relative attention. Conclusion - Through the results of this study, a study on the reinterpretation of past leadership studies, a study on LMX with an expanded perspective, and a study on integrated leadership sub-factors of modern leadership theory were proposed.
