본 연구는 모회사의 뉴스 감성이 자회사의 주가 등락에 영향을 주는지 파악하기 위해 네이버 뉴스를 수집하여 분석하였다. 뉴스의 감성을 처리하기 위해 KoELECTRA를 사용하였으며, 주가 등락 예측 모델로는 LSTM을 사용하였다. sequence size별 예측을 진행했으며 분석 결과, 모회사의 뉴스가 주가 등락에 영향을 끼쳤음을 확인하였다. This study used to KoELECTRA to collect and analyze Naver news to understand whether the sensitivity of parent company news affects the stock price of subsidiaries, and used LSTM as a predictive model of stock price fluctuation. We made predictions by sequence size, and as a result of the analysis, we confirmed that the news of the parnet company affected the stock price.

Objectives This study examined recent domestic and international clinical research trends in Gua sha therapy to suggest future direction for research. Methods We used six domestic and international databases (Research Information Sharing Service, Korean studies Information Service System, Oriental Medicine Advanced Searching Integrated System, PubMed, Embase, Cochrane Library) to select clinical studies with an original text in English or Korean published after 2018. Results Finally, 55 studies were selected. Randomized controlled trials accounted for the largest amount with 42 studies. Instrument assisted soft tissue mobilization was the most frequent term referring to Gua sha. Muscle shortening, limited range of motion, and plantar fasciitis were the most common symptoms, with six cases each. Additionally, there were two studies targeting symptoms other than the musculoskeletal system. Conclusions Additional research is needed on the effects of Gua sha therapy on the back of the lower extremities and hip joints, and research is needed on the possibility of their clinical use for diseases or symptoms other than those of the musculoskeletal system. And standards for the terminology of Gua sha and the types and methods of applied interventions are needed. (J Korean Med Rehabil 2024;34(1):23-38)
