  • Google Trends is a useful tool not only for setting search periods, but also for providing search volume to specific countries, regions, and cities. Extant research showed that the big data from Google Trends could be used for an on-line market analysis of opinion sensitive products instead of an on-site survey. This study investigated the market share of tumor necrosis factor-alpha (TNF-α) inhibitor, which is in a great demand pharmaceutical product, based on big data analysis provided by Google Trends. In this case study, the consumer interest data from Google Trends were compared to the actual product sales of Top 3 TNF-α inhibitors (Enbrel, Remicade, and Humira). A correlation analysis and relative gap were analyzed by statistical analysis between sales-based market share and interest-based market share. Besides, in the country-specific analysis, three major countries (USA, Germany, and France) were selected for market share analysis for Top 3 TNF-α inhibitors. As a result, significant correlation and similarity were identified by data analysis. In the case of Remicade's biosimilars, the consumer interest in two biosimilar products (Inflectra and Renflexis) increased after the FDA approval. The analytical data showed that Google Trends is a powerful tool for market share estimation for biosimilars. This study is the first investigation in market share analysis for pharmaceutical products using Google Trends big data, and it shows that global and regional market share analysis and estimation are applicable for the interest-sensitive products.

  • 4차 산업혁명이 등장한 이래로 산업 분야를 비롯한 다양한 분야에서 관련 연구들이 수행되었다. 본 연구에서는 4차 산업혁명에 대한 국내의 연구 동향을 분석하기 위하여 2016년 1월부터 2023년 8월까지 KCI에 수록된 2,115건의 논문을 대상으로 핵심어 분석 및 LDA 알고리즘에 기반한 토픽모델링 분석을 실시하였다. 본 연구의 결과 첫째, 4차 산업혁명 관련 학술 논문이 많이 게재된 학술지는 디지털융복합연구, 인문사회 21, e-비즈니스연구, 학습자중심교과교육연구 등의 순이었다. 둘째, 토픽모델링 분석 결과, '인간과 인공지능', '데이터와 개인정보 관리', '교육과정의 변화', '기업의 변화와 혁신', '교육의 변화와 일자리', '문화예술과 콘텐츠', '정보와 기업의 정책과 대응'의 7개 토픽이 선정되었다. 셋째, 4차 산업혁명과 관련한 공통 연구주제는 '교육과정의 변화', '인간과 인공지능', '문화예술과 콘텐츠'이며, 공통 키워드는 '기업', '정보', '보호', '스마트', '시스템' 등이 있다. 넷째, 연구 전반기(2016-2019)에는 교육 분야의 주제가 상위에 등장했으나 후반기(2020-2023)에는 기업과 스마트, 디지털, 서비스 혁신에 관한 주제들이 상위로 나타났다. 다섯째, 연구 후반기로 가면서 연구 주제들이 보다 구체화되거나 세분화되는 경향을 보였다. 이러한 동향은 코로나 팬데믹 이후 4차 산업혁명 분야의 핵심 기술들이 다양한 산업 분야에 활용됨에 따라 발생하는 사회경제적 변화에 따른 것으로 해석된다. 본 연구의 결과는 4차 산업혁명 분야의 연구 동향 파악과 전략 수립 및 후속 연구에 유용한 정보를 제공할 수 있을 것으로 기대한다.

  • As the development of artificial intelligence (AI) technology spreads to various industrial sectors, diversity in AI utilization rapidly increases, creating rich user experience. In addition, AI is required to solve various social problems through the use of public data. The spread of AI utilization across all sectors will continue, covering such industrial and public demands. This article examines the domestic and international trends in AI utilization technologies and establishes the direction of research and development (R&D), which is highly consistent with Korea's AI policy. ETRI, which leads AI's national R&D, has used its experience to establish AI R&D implementation strategies as well as technology roadmaps for the utilization of AI to improve individual quality of life, continuous growth in society, industrial innovation, and the solutions to public societal problems. In addition, it has derived tasks and implementation strategies for developing AI utilization technologies in 10 major areas including medical services.

  • Since the basic built-in-test, prognostic health management (PHM) has evolved into more sophisticated and complex systems with advanced warning and failure detection devices. Aerospace and military systems, manufacturing equipment, structural monitoring, automotive electronic systems and telecommunication systems are examples of fields in which PHM has been fully utilized. Nowadays, the automotive electronic system has become more sophisticated and increasingly dependent on accurate sensors and reliable microprocessors to perform vehicle control functions which help to detect faults and to predict the remaining useful life of automotive parts. As the complication of automotive system increases, the need for intelligent PHM becomes more significant. Given enormous potential to be developed lays ahead, this paper presents findings and discussions on the trends of automotive PHM research with the expectation to offer opportunity for further improving the current technologies and methods to be applied into more advanced applications.

  • Purpose - The paper analyzes basic indicators characterizing the volume of energy sector activity in the Russian Federation, Privolzhsky Federal district, Republic of Tatarstan. Research design, data, and methodology - The study analyzed data from the Privolzhsky Federal district, specifically, industrial production volume, electricity production, energy consumption, energy-balance data, capital investments, and capital investment structure. An array of data has been investigated in recent years. The dataset's dynamics were analyzed in 1998. Fixed capital investment dynamics were studied in 1946 the figures were converted to a comparable form using the index method. Trends were analyzed using multivariate statistics methods and the Statgraphics software package. Results - Hypothesis 1. There are sectoral disproportions in energy flows,taking into account the volume of electricity production and consumption. Trends in electricity production in general coincide with industrial production volume trends. Energy flows have disparities in individual territorial units, and in general. Hypothesis 2. The degree of sectoral economic stability decreases with insufficient levels of investment in fixed capital energy organizations. Conclusions - Because totalelectricity production is largely determined by fixed capital investments, the study of their trends and patterns will coordinate efforts on investment operations in this area.
