COVID-19, which started in December 2019, has had a great impact on our lives in general, including politics, economy, society, and culture, and activities in sports and arts have also been significantly reduced. In the case of sports, sports for all fields in which ordinary citizens participate were particularly affected, and cases of infection in places closely related to people's lives, such as gyms, table tennis, and badminton clubs, also amplified the social fear of the spread of COVID-19. Therefore, in this study, we analyzed news articles related to sports for all at the time when COVID-19 was first spread, and investigated what issues were emerging and being discussed in the sports for all field under the COVID-19 situation. Specifically, we collected news articles dealt with sports for all issues under the COVID-19 situation from Korea's leading portal news sites and identified key sports for all issues by performing topic modeling on these articles. Through the analysis, we found meaningful issues such as COVID-19 outbreak in sports facilities and support for sports activities. In addition, through wordcloud analysis of these major issues, we visually understood the issues and identified the changes in these issues over time.

The easy payment service is a payment and remittance service that uses a simple authentication method. As online transactions have increased due to COVID-19, the use of an easy payment service is increasing. At the same time, electronic financial industries such as Naver Pay, Kakao Pay, and Toss are diversifying the competition structure of the easy payment market; meanwhile overseas fintech companies PayPal and Alibaba have a unique market share in their own countries, while competition is intensifying in the domestic easy payment market, as there is no unique market share. In this study, the participants in the easy payment market were classified as electronic financial companies, mobile phone manufacturers, and financial companies, and a SWOT analysis was conducted on the representative services in each industry. The analysis examined the user reviews of Google Play Store via a topic modeling analysis, and it employed positive topics as strengths and negative topics as weaknesses. In addition, topic modeling was conducted by dividing news articles into political, economic, social, and technology (PEST) articles to derive the opportunities and threats to easy payment services. Through this research, we intend to confirm the service capabilities of easy payment companies and propose a service activation strategy that allows gaining the upper hand in the market.

The purpose of this study is to diagnose the current status of alternative materials in Korea and to suggest directions and goals for the development of alternative materials. The comprehensive list of national alternative materials and the list of popular and new books were analyzed using the collection evaluation method. Results first the percentage of alternative material collections based on the popular book list for 10 years is 90.1%. The production rate of alternative materials is low in the subjects of 'Language', 'Art' and 'Technology and Science'. Most of the service formats were 'text only daisy'. Second, the CCHR(Common Collection Holding Ratio) and CUI(Collection Uniqueness index) of alternative materials were analyzed using the union catalog. Libraries with a large volume of books have a high proportion of CCHR and CUI. Topics with the highest CCHR are 'Literature' and 'Social Science'. The subjects with the highest collection uniqueness index are 'religion', 'art', and 'language'. Third, the replacement ratio of new books for 3 years is 5.09%. During the same period, the average book purchase rate of public libraries was 8.83%. The average book purchase rate in public libraries is 8.83%, and it is necessary to increase the collection rate of alternative materials based on this ratio.

Information extraction can facilitate the intensive analysis of documents by providing semantic triples which consist of named entities and their relations recognized in the texts. However, most of the research so far has been carried out separately for named entity recognition and relation extraction as individual studies, and as a result, the effective performance evaluation of the entire information extraction systems was not performed properly. This paper introduces two models of end-to-end information extraction that can extract various entity names in clinical records and their relationships in the form of semantic triples, namely pipeline and joint models and compares their performances in depth. The pipeline model consists of an entity recognition sub-system based on bidirectional GRU-CRFs and a relation extraction module using multiple encoding scheme, whereas the joint model was implemented with a single bidirectional GRU-CRFs equipped with multi-head labeling method. In the experiments using i2b2/VA 2010, the performance of the pipeline model was 5.5% (F-measure) higher. In addition, through a comparative experiment with existing state-of-the-art systems using large-scale neural language models and manually constructed features, the objective performance level of the end-to-end models implemented in this paper could be identified properly.

What this study aims is to analyze that how the stories of Prince Hodong are represented in modern historical fictions. The stories have been reproduced in many forms such as TV dramas, films, fictions, plays. It can be depicted that the narratives are indeed national and popular. Interestingly, however, the description of Hodong has not been found in pre-modern documents or fictions. The story began to appear and became popular in 1935 by Yoon Baek Nam. It can be explained that the narratives are the one of the example of the invented tradition since it became visible in modern period. Yoon, Lee Tae Joon, and Yu Chi Jin have constructed the character of Hodong what we are familiar with. Yoon depicted Hodong as a romatic lover with the motif of a lovers suicide. Lee and Yu put a context of nationalism by explaining Nakrang as a Nakrangkun of Hansagun(the four colonies of China). These are pure invention of the writers which cannot be found in The History of Three Kingdoms(三國史記). These characters are closely related with the surrounding of their own society. Yoon shows how the past can be seen as a nostalgic object by modern aesthetic perspective. Lee illustrates the ambiguous thought of a colonial intellectual who (anti)internalizes the ideology of militarism. Yu tries to find the way to recover the muscularity of the nation by re-colouring the memory of the past. These, the representations created in various contexts, make our common knowledges of Prince Hodong nowadays.

Recently, the number of SNS user has rapidly increased due to smart device industry development and also the amount of generated data is exponentially increasing. In the twitter, Text data generated by user is a key issue to research because it involves events, accidents, reputations of products, and brand images. Twitter has become a channel for users to receive and exchange information. An important characteristic of Twitter is its realtime. Earthquakes, floods and suicides event among the various events should be analyzed rapidly for immediately applying to events. It is necessary to collect tweets related to the event in order to analyze the events. But it is difficult to find all tweets related to the event using normal keywords. In order to solve such a mentioned above, this paper proposes A Generation and Matching Method of Normal-Transient Dictionary for realtime topic detection. Normal dictionaries consist of general keywords(event: suicide-death-loop, death, die, hang oneself, etc) related to events. Whereas transient dictionaries consist of transient keywords(event: suicide-names and information of celebrities, information of social issues) related to events. Experimental results show that matching method using two dictionary finds more tweets related to the event than a simple keyword search.

Family films with insight of the society are now recognized as significant texts to communicate with audience from the beginning of the history of film and to reflect various viewpoints on changes of the times and socio-cultural context. In such aspect, the films of Hirokazu Kore-eda are very significant in that they suggest very sharp view on modern society through family narrative. His family narratives not only presented a profound reflection on the modern society and human relations through themes on death, loss, severance, and alienation, but also formed a public sympathy based on success in the box-office numbers despite his heavy subjects. His such achievement is closely related to the format of spatial representation to record 'time' and 'daily life' as well as the family film as a narrative form to draw the meaning of a family. Therefore, this study analyzes the family narrative and the format of spatial representation in the films of Hirokazu Kore-eda, and could find the film form where life and space closely communicate each other to reach the topic. This study, concentrating on the spatial representation and the roles and meanings of formal factors in family narrative, can find its own value in its expansion out of the previous studies which adopted macro perspectives on the trend of the times.

This study investigated the overall perceptions of pre-service school librarian teacher on the current education practicum through semi-structured in-depth interviews and suggested improvements to the educational practicum system. For this purpose, interview data were collected from 28 pre-service school librarian teacher (6 teachers' colleges, 14 taking teaching qualification courses, and 8 graduate school of education) who participated in educational practicum in school libraries, and a research method that combines qualitative analysis techniques with text network analysis was applied. The results of the study showed that pre-service school librarian teacher believe that educational practicum can prepare them for various field experiences and cultivate their ability to cope with situations they will encounter in the future. Through qualitative inquiry, we were able to identify their perceptions of school field practicum as a whole, their perceptions of the school field practicum, and their perceptions of educational service activities. Based on this, to improve the current problems of educational practice, we suggested expanding the period of school internship program, distributing the time, establishing a full-time practice system, having continuous discussions with field teachers, and developing a systematic school field practicum.
