  • The article provides a literary and analytical review in the following areas of search: problems and prerequisites for changes in the field of education, innovations and innovative models in education, the use of new technologies in teaching. A proposal for a business plan and accompanying documentation for a new methodology based on blockchain technologies were developed, to assess the economic efficiency of the project. The main systems of the new model were modeled on the basis of the proposed methodology, to develop a prototype based on the project documentation.

  • The paper investigates investor sentiment's role in boosting Japanese companies to enhance their environmental, social, and corporate governance (ESG) performance. Using ESG scores of 367 firms between 2005 and 2019 from the ASSET4 database, we find that negative sentiment in the previous year, both firm and market level, can be a stimulation for the company's commitments to its ESG activities next year. Notably, the moderating effect of the business sector and economic cycle on the sentiment-ESG inference are detected in our study differentiating between corporate and market sentiment, which have never been reported before. In detail, we discover that the impact of firm-specific sentiment is less pronounced for high-sensitive ESG firms. On the other hand, the driving force of market sentiment on corporate social behaviors weakens when economic recessions happen. Our results are robust after controlling for potential endogeneity issues and using alternative proxies for market sentiment.

  • This study reviews the analysis and characteristics of databases from big data and then establishes representational strategy. Thus, analysis has continued for a long time in the quantity and quality of data, and there are changes in the location of data in the social sciences, past trends and the emergence of big data. The introduction of big data is presented as a prototype of new social science and is a useful practical example that empirically shows the need, basis, and direction of analysis through trend prediction services. Big data provides a future perspective as an important foundation for social change within the framework of basic social sciences.

  • 헌재, 대부분의 여론조사는 전통적 여론 조사 방식을 사용하고 있다. 그러나 이 방식은 온라인 상에서의 여론을 반영하지 못한다는 문제점이 존재한다. 따라서 이를 해결하고 온라인 상에서의 여론을 반영하기 위해, 비정형 뉴스 데이터를 이용한 지지율 분석 방안을 제안하고자 한다. 이 연구에서는 제안 방안을 알아보고 기존의 방식과 비교한 장단점, 시사점, 개선방안 등을 알아봄으로써 새로운 여론조사 방식의 제안을 목적으로 한다.

  • 최근 ICT 산업게는 가상현실에 주목하고 있다. 시공간의 제약을 극복하고 실제 체험하는것과 비슷한 효과를 제공하는 VR 콘텐츠는 향후 유통 분야에도 폭넓은 활용이 예상된다. 대부분의 O2O 서비스에서 사용하고 있는 VR 기술은 단순히 360도 파노라마 형식의 사진을 보여주거나 VR 카메라로 중계 방송을 하는 콘텐츠가 대부분이었다. 따라서 본 논문에서는 3차원 VR 영상 스트리밍 서비스를 이용한 콘텐츠를 O2O 부동산 중개 서비스에 접목하여 360VR 컨텐츠 확장 가능성을 제시하고자 한다.

  • The history of statistics from the mid-seventeenth to the early twentieth century is considered and a scheme of periodization is proposed. In the first period(1650-1750), named 'the age of probability' in this paper, concept of probability emerged, and in the second period(1750-1820), named 'the age of error theory', statistical techniques such as the least square method are developed by astronomers and geodesists. Their techniques are supported theoretically by mathematicians like Laplace and Gauss in that period. The third period(1820-1880) is called 'the age of statistics(as a plural noun)' since statistical data played prominent roles in social sciences such as sociology, psychology. Finally the last period(1880- ), called 'the age of statistics(as a singular noun)', the discipline of statistics came to maturity both in theory and application.
