Text data mining ('big data methods') is one of the most widely used approaches during the COVID-19 pandemic. In particular, text data mining on Scopus databases or Web of Science (WoS). Text data mining is widely used to collect literature for later bibliometric analysis, and in the end, it becomes a literature review article. Therefore, in this article, we reveal the trend of publication of literature reviews in Scopus journals from Indonesia, Japan, South Korea, Vietnam, Singapore, and Malaysia. This article describes two essential parts, namely 1) a comparison of international publication trends and subject area of literature review publications, and 2) a comparison of Top 5 for Authors, Affiliation, Source Title, and Collaboration Country.

Recently, with the introduction of social network services, studies that try to make use of them for the various purposes have been actively developed. In order to proceed with the research that takes advantage of social network services, it is necessary to review the relevant literature and to identify trends in researches. However, the researches of social network service since 2007 are massive amount, so to review the huge amount of relevant research literature is a very difficult task. Therefore, in this study, we analyze systematically the tendency of research related to social network service focusing on Twitter. Especially, we use the SLR(Systematic Literature Review) technique for systematic literature survey and analysis. For the literature survey, we select five well-known literature resource sites and 128 studies of literature that are surveyed. In order to identify various research trends, we conduct the survey with two research groups: researches since 2007 and researches since 2011. As a result of the investigation, since 2007, the researches associated with "Application", "User Activity" and "User Content Analysis" main study topics have been mostly carried out. In addition to the result, the trend of secondary study topics in a main study topic, trends in research based on the number of citations and the scale of the experimental data and characteristics of the author are analyzed from a variety of perspectives.

The purpose of this study is to investigate the research trends and the present conditions of real digital texts on "Visual Transformation." For the purpose of this study adopted two different methods: meta analysis and case study. The research trends on visual transformation of digital text were investigated through analyzing the total of 167 literature by means of synthetic meta analysis. Relevant literature was categorized into three types of research: functional, dynamic, and interactional transformation. The type of literature and research methods in each literature were analyzed. The present conditions of real digital texts on visual transformation were investigated by means of case study. The well designed 12 e-learning contents selected and analyzed in terms of the analysis framework which was drawn by the research trends. The results suggested problems as follows in designing e-learning contents. Firstly, there were some cases that did not follow the basic design principles related to typography. Secondly, the content was just provided in each learning steps without consideration of design to enhance text comprehension in many cases. Thirdly, web technology adequately was not applied to design e-learning contents.

The purpose of this article is to take a look into the past twenty years and to evaluate the changes in the organization of the library and the information function during this time period. Academic and special libraries are the ones that have made an impressive progress and innovations to keep pace with a changing environment. New technologies and ideas have brought strong supporters of offering various specialized information services to the library users. The different approaches and experiments to better perform this professional role in the library and in turn, the efforts in the educational institutions to meet the challenges were reviewed through the literature. Much of the literature available regarding the reference and information function deals mainly with the trends in the u. s. libraries. The implications of these trends to Korean libraries and library education are sought in view of our social, economic, and educational circumstances as well as our user behavior.

There are several problems facing our society today that are caused by demographic changes, such as an increase in the ageing population. The rapid increase in the aging population leads to increases in medical costs and a higher demand for care services for the elderly. The needs and burdens associated with elderly care are growing, but the human resources and costs to meet these needs are limited. Welfare technology has been suggested as an effective way to solve the discrepancy between higher welfare needs and limited resources. This study aims to explore the current trends and challenges of using welfare technology related to elderly care through literature review. Practical ways to expand uses of welfare technology are also provided. In order to make effective and practical use of welfare technology, public awareness and education, the cooperation of related organizations, the expansion and utilization of Living Labs, and the development and adoption of welfare technology are required.
