There have been little comprehensive research for studying impact of foreign journals on Korean scientists. The main reason for this is because there was no extensive citation index database of domestic journals for analysis. Korea Institute of Science and Technology Information (KISTI) built the Korea Science Citation Database (KSCD), and have provided Korea Science Citation Index (KSCI) and Korea Journal Citation Reports (KJCR) services. In this article, citing behavior of Korean scientists on foreign journals was examined by using KSCD that covers Korean core journals. This research covers (1) analysis of foreign document types cited, (2) analysis of citation counts of foreign journals by subject and the ratio of citing different disciplines, (3) analysis of language and country of foreign documents cited, (4) analysis of publishers of journals and whether or not journals are listed on global citation index services and (5) analysis for current situation of subscribing to foreign electronic journals in Korea. The results of this research would be useful for establishing strategies for licensing foreign electronic journals and for information services. From this research, immediacy citation rate (average 1.46%), peak-time (average 3.9 years) and half-life (average 8 years) of cited foreign journals were identified. It was also found that Korean scientistis tend to cite journals covered in SCI(E) or SCOPUS, and 90% of cited foreign journals have been licensed by institutions in Korea.

This study examines the way of making use of the science journals sharing with many users, who even do not work for the same institute. It may help to make the information as much as available with minimum financial burden to users. This is needed expecially when we recognize the fact that the amount of information supply is being increased rapidly while the financial environments around us are becoming aggravated.

To improve the international competitiveness of research and academic libraries in Korea, it is essential to review the total amount of domestic information resources in comparison with those of other advanced countries, and then to make their best use. In this study, an attempt is made to estimate the annual budget for collecting foreign knowledge information resources spent by academic and research libraries in Korea. This budget estimate could be used for a basis for setting up the appropriate collection size and the efficient channel for distributing and sharing information resources among academic and research libraries on the governmental level. The total budget for collecting foreign knowledge information resources, including foreign monographs and scholarly journals in print, and the budget for foreign electronic journals, and web databases were estimated for academic libraries and research libraries, respectively, while the budget for international document delivery services was estimated without distinction between the types of libraries.

Nowadays many academic libraries have considered and some have implemented the just-in-time(access) approach to collection development especially of scholarly journals. The adaption of the scholarly electronic journal based on access paradigm has brought a number of advantages and disadvantages to academic libraries. Electronic journals have promised rapid delivery of the latest research to the desktop through the ubiquitous platform of the Internet. But the promise of the e-journal is not yet a reality, and there are many misconceptions about what is actually available today. The objective of this paper is to analyse the probabilities of digital achilles tendon of scholarly journals resulting from a decline of purchase power, absence of selection(evaluation) criteria, superfluities and abuses of impact factor, access paradigm and halo effects, mismatching of demand-supply, md insufficiency in subject gateway functions.

This study aims to research the influences of the discrimination of internet media and one-person media environment, especially, the one-person media creators leading the mobile media that could be accessed and viewed anywhere, on the user attitude and continuous subscription intention. Especially, this study aimed to understand the current situation of one-person media market represented as YouTube, to explore the relationship and ecology between each subject and elements composing the media market, and also to understand the mediating effects of the characteristics of YouTube creators on the relation between contents involvement and user attitude, and the relation between user attitude and subscription intention, and the mediating effects of contents involvement on the relation between characteristics of creators and user attitude. As research methods, first, for the theoretical establishment, this study collected, conducted, and organized the published domestic/foreign theses/journal papers. For the objective validity and verification of the established research model, a survey was conducted targeting adult men and women currently watching YouTube, and then the empirical analysis was performed through the final effective samples. And the results of this study are as follows. First, the playfulness and reliability on the relation between characteristics of creators and contents involvement were not significant while the professionalism was significant. Second, the professionalism on the relation between characteristics of creators and user attitude was not significant while the playfulness and reliability were significant. Third, the relation between contents involvement and user attitude was significant. Fourth, the relation between user attitude and subscription intention was also significant. Also, in the results of verifying the mediating effects of contents involvement, the contents involvement completely mediated the relation between characteristics(playfulness, reliability, and professionalism) of creators and user attitude. And in the conclusion, this study presented the implications and suggestions for further researches in the future.

The purpose of this study is to lay the groundwork for internationalization of domestic journals in the field of Library and Information Sciences (LIS). This study analyzed the characteristics and trends of 7,302 papers from 38 SSCI journals and 768 papers from 4 domestic journals in LIS. Results show the publication and citation counts of domestic journals to be more evenly distributed than those of international journals, which suggests the presence of core international journals. In addition, citation rates and co-authored papers of international journals are shown to be much higher than that of domestic journals, suggesting that international journals publish research papers of higher impact and collaboration.

In this study, models for predicting the popularity of mukbang content on YouTube were proposed, and factors influencing the popularity of mukbang content were identified through post-analysis. To accomplish this, information on 22,223 pieces of content was collected from top mukbang channels in terms of subscribers using APIs and Pretty Scale. Machine learning algorithms such as Random Forest, XGBoost, and LGBM were used to build models for predicting views and likes. The results of SHAP analysis showed that subscriber count had the most significant impact on view prediction models, while the attractiveness of a creator emerged as the most important variable in the likes prediction model. This confirmed that the precursor factors for content views and likes reactions differ. This study holds academic significance in analyzing a large amount of online content and conducting empirical analysis. It also has practical significance as it informs mukbang creators about viewer content consumption trends and provides guidance for producing high-quality, marketable content.

The scholarly communication crisis is not a journals crisis, but rather a broader crisis in information communications. It is the loss of access to the scholarly research literature, as the rising cost of STM journal subscriptions far out-strip academic library budgets. Now, the open access as alternatives to traditional journal subscription model are emerging for STM scholarly information. There are basically three forms for OA strategies : Open Access Journals(OAJ), Author Self Archiving(ASA), Academic Institutional Repositories(AIR). This paper describes the current trends and analyses potentially serious limitations and obstacles or various issues of the OA strategies, including the notion of scholarly information as a public good, myths of free access, author pay model, holder of copyright, etc.
