For the study 131 journal articles taken from three scholarly journals in the field of Economics. Public Administration, and Library and Information Science are selected and all analyses are taken in terms of the material types, the publication place, and the publication year of the papers cited by those journal articles. In result, it was found that the half-life of monographs is 6.76, that of scholarly journal articles 8.07, that of reports 6.49, and that of theses 3.45. Also, the study finds that most researchers in those field, cited more articles published in foreign countries(67.79%) that those published from Korea(32.21%).

  • In this paper, We propose a document thematic words extraction by using principal component analysis(PCA) which is one of the multivariate statistical methods. The proposed PCA model understands the flow of words in the document by using an eigenvalue and an eigenvector, and extracts thematic words. The proposed model is estimated by applying to document summarization. Experimental results using newspaper articles show that the proposed model is superior to the model using either word frequency or information retrieval thesaurus. We expect that the Proposed model can be applied to information retrieval , information extraction and document summarization.

  • Recently, people are using the data analysis in order to follow the new trend in information and communication technology. Media plays an important role to expand the new issue in our society, especially affected to establish social awareness about science and technology. So, We find some major technologies (Machine Learning & Blockchains) of future communication and information based on the 200 news articles through two data analysis methods such as keyword analysis and sentiment analysis.

  • In this paper, we suggest a Coreference Resolution system for Korean using Mention Pair with SVM. The system introduced in this paper, also be able to extract Mention from document which is including automatically tagged name entity information, dependency trees and POS tags. We also built a corpus, including 214 documents with Coreference tags, referencing online news and Wikipedia for training the system and testing the system's performance. The corpus had 14 documents from online news, along with 200 question-and-answer documents from Wikipedia. When we tested the system by corpus, the performance of the system was extracted by MUC-F1 55.68%, B-cube-F1 57.19%, and CEAFE-F1 61.75%.

  • The purpose of this study was to compare the job stress, job satisfaction, turnover intention, and job performance feelings of radiological technologists, physical therapists, and medical laboratory technologists working at university hospitals and general hospitals. The subjects were 114 general practitioners and 217 university hospital workers who are engaged in occupations of radiological technologists, physical therapists, and medical laboratory technologists in the age groups 20-50 years living in Incheon Metropolitan City. Data collection was conducted from April 1, 2017 to April 30, and data analysis was performed using the SPSS/WIN 23 statistical program. There were statistically significant difference in the job stress of medical technician by age, marriage, occupation, hospital size, position, parenting form, employment type, and lunch break. Job stress by occupation was highest in medical laboratory technologists, followed by radiological technologists and physical therapists. Job satisfaction was the highest among physical therapists. followed by radiological technologists and medical laboratory technologists. There were significant differences in age, occupation, parenting form, type of employment, and lunch break according to demographic characteristics. In order to reduce the job stress and job satisfaction of the medical technician working at the hospital, the development of the job environment should be sought and the hospital should also be removed from the authoritarian management system.

Methods: The data for occupational accident compensation insurance coverage and occupational accidents from 2012 to 2017 were analyzed through descriptive statistics. Results: Rates of occupational accident compensation insurance coverage of special-type delivery workers decreased gradually from 43.4% in 2012 to 28.5% in 2016, and 29.0% in 2017. Rates of occupational illnesses death per ten thousand workers increased gradually from 2.1‱ in 2013 to 3.1‱ in 2016, and 8.6‱ in 2017. All occupational illness deaths were due to cerebro-cardiovascular diseases. Road traffic accidents and slips accounted for the largest proportion of occupational accidents. Conclusion: Special-type delivery workers have a high risk of industrial accidents, so it is necessary to raise industrial accident insurance coverage and provide professional and systematic occupational safety and health services.

Considering that the Chinese market plays a pivotal role in the global fashion industry, big data was collected in the most famous and professional fashion network in China, LADYMAX.cn. As a result of text mining and social network analysis, three major changes were identified as the emerging fashion consumption culture in the post-COVID-19 era. First, as a trend in new media consumption, COVID-19 disease and the development of digital technology tended to encourage consumers to put more importance on the relationship between bloggers and fans than previously. Second, as a trend in reward consumption, consumers tended to be rewarded for their hard work to relieve and comfort their high stress caused by spending a long time worrying about the prolonged COVID-19 situation. Third, as a trend in home-economy consumption, consumers tended to prefer homewear and sportswear more because they were spending longer times at home as the social distancing period was prolonged.
