  • With the development of the economy and the improvement of living standards, the hot issues in the subject area have become the main research direction, and the mining of the hot issues in the subject currently has problems such as a large amount of data and a complex algorithm structure. Therefore, in response to this problem, this study proposes a method for extracting hot keywords in scientific journals based on the improved BERT model.It can also provide reference for researchers,and the research method improves the overall similarity measure of the ensemble,introducing compound keyword word density, combining word segmentation, word sense set distance, and density clustering to construct an improved BERT framework, establish a composite keyword heat analysis model based on I-BERT framework.Taking the 14420 articles published in 21 kinds of social science management periodicals collected by CNKI(China National Knowledge Infrastructure) in 2017-2019 as the experimental data, the superiority of the proposed method is verified by the data of word spacing, class spacing, extraction accuracy and recall of hot keywords. In the experimental process of this research, it can be found that the method proposed in this paper has a higher accuracy than other methods in extracting hot keywords, which can ensure the timeliness and accuracy of scientific journals in capturing hot topics in the discipline, and finally pass Use information technology to master popular key words.

  • Information and communication technology (ICT) is increasingly recognized as an important driver of economic growth, innovation, employment and productivity and is widely accepted as a main feature of development. During the last couple of decades, ICT sector became the most innovative service sector that affected the living standards of human beings all over the world. In the beginning of the $21^{st}$ century, some of the Asian countries made reforms in the ICT sector and spent an enormous amount for the progress of this sector. On the other hand, developed countries in the European Union (EU) faced different crises which badly affected the dissemination of this sector. Consequently, EU countries lost their hegemony in the field of information technology and resultantly, some of the emerging Asian countries like China, India, and South Korea got supremacy over the EU in this field. Currently, these countries have a strong IT infrastructure, R&D sector, IT research centers working for the development of ICT. Moreover, this paper investigates reasons for the shifting of the balance of digital power from Europe to Asia.

  • Consumer information influences purchasing behavior; however, less is known about the relationship in the credit market. Credit markets offer consumers a complex array of different products when choosing mortgages. The current study examines whether borrowers search for the very best terms when making major decisions about borrowing money or obtaining credit as well as explores the relation between consumer information seeking and the cost of credit. This study demonstrates the existence of price dispersion between those who made an extensive information seeking and those who did not. When controlling for the proxies of creditworthiness and demographics of the respondents, it is found that those who made a great deal of information seeking tend to have lower mortgage rates than those who made almost no information seeking. This study offers financial educators and policy makers suggestions on how to help consumers make better financial decisions.

  • ChatGPT의 교육적 활용에 대한 관심이 증가하고 있는 시점에서 대학생을 대상으로 ChatGPT에 대한 인식을 알아보는 것은 필요하다. D대학교 2023년도 1학기 '가정생활과 문화', '패션과 미술관', '영화로 만나는 패션' 수강생을 대상으로 인터넷과 대화형 인공지능 사용실태 그리고 수업에서 ChatGPT를 활용한 후 그에 대한 인식을 설문지, 비교분석 보고서, 성찰일지로 살펴보았다. 대학생은 수업을 위한 정보는 주로 인터넷 검색과 논문에서 주로 얻고 있었으며 대화형 인공지능을 이용하는 경우는 아직 미비함을 알 수 있었다. ChatGPT는 대부분 2023년 1학기에 처음 사용하였으며 대화형 인공지능 중 주로 ChatGPT를 사용하였다. ChatGPT는 정보의 정확성과 신뢰도면에서는 조금 부족하나 쉽고 빠르게 상호작용을 하면서 정보를 찾을 수 있어 편리하며 만족도가 높아 앞으로 ChatGPT를 보다 적극적으로 활용할 용의가 있었다. ChatGPT가 교육에 미치는 영향에 대해 학생들은 자기 주도적이며 질문을 통한 문제해결 태도와 정보에 대한 검증과정을 위해 모둠별 토의·토론을 통해 확인하는 협동수업의 과정을 학습자 스스로가 설정하는 것이 긍정적이라고 하였다. 그러나 표절과 저작권, 데이터 편향성, 최신 데이터 학습부족, 정확하지 않거나 잘못된 정보를 생성하는 등의 신뢰를 저하시키는 문제점이 있다는 것을 인식하였으며 이에 대한 보완이 필요하다고 하였다.
