COVID-19 has been affecting the library, not to mention society as a whole. Especially, there are many changes in the role and service of the university libraries as all the classes of the universities are turned into non-face-to-face and the use of the university libraries is restricted. The changes in users' use of information and communication behavior due to COVID-19 could be an opportunity for new utilization of human and material resources the university libraries have and for the development of services. However, on the contrary, the university libraries could face another crisis if they fail to respond appropriately to current changes. Therefore, it is necessary to grasp, analyze the impact of COVID-19 and plan how to respond. A survey on the effects of COVID-19 and the response of the university libraries and the perceptions of the university libraries found that most university libraries are responding appropriately to COVID-19. However, a survey on the perceptions of the present and future of the university libraries under COVID-19 showed that many survey respondents think COVID-19 would have a negative impact on the university libraries. This means that the changes caused by COVID-19 are causing a crisis and anxiety in the university libraries. Therefore, by working hard together, the university libraries need to present the university libraries' new role, service and direction in the post-COVID-19 era as well as responding to the current situation.

Due to COVID-19, user instruction programs could not be conducted face-to-face, and the sessions have been moved online. The present study attempted to investigate how online user instruction influences the information literacy ability of college students. The study randomly selected college students (N=50) who completed online user instruction sessions and college college students (N=50) who did not complete them among freshment who went to to college in 2020 to measure their information literacy abilities. For this study, a tool for measuring information literacy abilities was developed by referring to several previous studies. The measurement results were analyzed by the independent samples t-test, and significant differences were found between students who completed online user instruction sessions and those who did not. The findings of the study have confirmed that it is effective in enhancing library users' information literacy abilities to provide user instruction online under the COVID-19 situation, and even in post-COVID 19 times, which helps them appropriately utilize the characteristics of digital libraries. The information literacy measurement tool used in the present study was developed to evaluate online information literacy, and thus contributed to the extension of the literature of digital information literacy and user instruction. The present study provided practical implications for how academic libraries will promote information services to cope with environmental changes in which contact-free (untact) services are obliged.

The purpose of this study is to identify the problems of describing bibliographic elements such as edition, impression, and year of publication in the current Cataloging Rules, and to present improvements to the KCR and the KORMARC Format. According to changes in the information technology environment in the library, the level and scope of the cataloging that can be provided to users should be adjusted. As data is diversified and descriptive method of metadata develops, the development of bibliographic elements and the change of the descriptive method are changing the framework of the existing standardization. As a research method, we will examine the concept of edition and impression, examine the transition process of description of edition and impression targeting KCR. And we would like to present the methods of bibliographic description to be added or modified through cataloging examples, and examine the format reflected in KORMARC. This study is intended to be limited to the descriptive form of books. The bibliographic elements of the entry in the library must be fully consistent with the bibliographic elements of the material to be catalogued. This study suggests an improvement to the cataloging rules. First, the edition of the cataloging rules shall describe the edition statement and the impression statement. In addition, the description of the year of publication describes the latest year, not the first year of publication of the edition of the material to be catalogued. The descriptive scope of the year of publication is extended to the month of publication. Second, in the KORMARC format, the description of impression in edition statement is given to the identifier in the 250 field, and is numerically described as the second impression. When presenting the month and year of publication, one identifier in the field 260 describes the year of publication and the other identifier describes the month of publication. The description for the month and year of publication is stated the latest month and year on the title page and the colophon of the publication.

It is not easy for information users to find books that are suitable for them in a knowledge information society. There is a growing need for libraries to break away from traditional services and provide user-tailored recommendation services, but there are few qualitative studies on user satisfaction so far. In this study, a user-customized book recommendation was performed by applying Apriori, a correlation analysis algorithm, and satisfaction factors were analyzed in depth through interviews. The experimental data was the loan data of 100 people who used the most frequently used loan data for 10 years from 2009 to 2019 of the S library in Seoul. The interviewees of the experiment were those who could be interviewed in depth. After the correlation analysis, the concepts and categories derived by analyzing the interview data were 59 concepts, 6 sub-categories, and 2 upper categories, respectively. The upper categories were 'reading' and 'book recommendation service'. In the 'reading' category, there were 16 concepts of motivation for reading, 8 concepts of preferred books, and 12 concepts of expected effects. Also, in the category of 'reading recommendation service', there were 10 'reflection factors', 4 'reflection methods', and 9 'satisfaction factors'.

This study investigates ethical dilemmas of teacher-librarians in their professional practice. Within the framework of "Librarians' Statement of Ethics" by Korean Library Association, the study used the survey and semi-structured interview with teacher-librarians. 259 teacher-librarians responded the survey and 5 teacher-librarians participated the interview. The survey was analyzed using descriptive statistics to find how often teacher-librarians experience ethical dilemmas. The semi-structured interview was transcribed and analyzed to draw the individual cases of teacher-librarians' ethical dilemmas. The results indicate that teacher-librarians experience ethical dilemmas in relation to information access and intellectual freedom most often. It was difficult for teacher-librarians to relate their professional duties with their expertise and that they were not clear on how to avoid copyright issues and how to deal with the balance between users and copyright holders. This study had implications that individual dilemma cases are so context-dependent that teacher-librarians had to make decisions individually. They tried hard to find the balance between protecting students from harmful resources and library ethics. Researchers and practitioners need focus more on finding where the balance is and how teacher-librarians deal with their ethical dilemmas.

The purpose of this study is to propose a book recommendation system that can be used in school libraries. The book recommendation system applies an algorithm based on association rules using DLS lending data and is designed to provide personalized book recommendation services to school library users. For this purpose, association rules based on the Apriori algorithm and betweenness centrality analysis were applied and detailed functions such as descriptive statistics, generation of association rules, student-centered recommendation, and book-centered recommendation were materialized. Subsequently, opinions on the use of the book recommendation system were investigated through in-depth interviews with teacher librarians. As a result of the investigation, opinions on the necessity and difficulty of book recommendation, student responses, differences from existing recommendation methods, utilization methods, and improvements were confirmed and based on this, the following discussions were proposed. First, it is necessary to provide long-term lending data to understand the characteristics of each school. Second, it is necessary to discuss the data integration plan by region or school characteristics. Third, It is necessary to establish a book recommendation system provided by the Comprehensive Support System for Reading Education. Based on the contents proposed in this study, it is expected that various discussions will be made on the application of a personalization recommendation system that can be used in the school library in the future.

The understanding and capability to utilize artificial intelligence (AI) incorporated technology has become a required basic skillset for the people living in today's information age, and various members of the university have also increasingly become aware of the need for AI education. Amidst such shifting societal demands, both domestic and international university libraries have recognized the users' need for educational content centered on AI, but a user-centered service that aims to provide personalized recommendations of digital AI educational content is yet to become available. It is critical while the demand for AI education amongst university students is progressively growing that university libraries acquire a clear understanding of user intention towards an AI educational content recommender system and the potential factors contributing to its success. This study intended to ascertain the factors affecting acceptance of such system, using the Extended Technology Acceptance Model with added variables - innovativeness, self-efficacy, social influence, system quality and task-technology fit - in addition to perceived usefulness, perceived ease of use, and intention to use. Quantitative research was conducted via online research surveys for university students, and quantitative research was conducted through written interviews of university librarians. Results show that all groups, regardless of gender, year, or major, have the intention to use the AI-related Educational Content Recommendation System, with the task suitability factor being the most dominant variant to affect use intention. University librarians have also expressed agreement about the necessity of the recommendation system, and presented budget and content quality issues as realistic restrictions of the aforementioned system.

This study proposed and evaluated electroencephalography (EEG)-based and eye-tracking-based methods to determine relevance by utilizing users' implicit relevance feedback while navigating content in a digital library. For this, EEG/eye-tracking experiments were conducted on 32 participants using video, image, and text data. To assess the usefulness of the proposed methods, deep learning-based artificial intelligence (AI) techniques were used as a competitive benchmark. The evaluation results showed that EEG component-based methods (av_P600 and f_P3b components) demonstrated high classification accuracy in selecting relevant videos and images (faces/emotions). In contrast, AI-based methods, specifically object recognition and natural language processing, showed high classification accuracy for selecting images (objects) and texts (newspaper articles). Finally, guidelines for implementing a digital library interface based on EEG, eye-tracking, and artificial intelligence technologies have been proposed. Specifically, a system model based on implicit relevance feedback has been presented. Moreover, to enhance classification accuracy, methods suitable for each media type have been suggested, including EEG-based, eye-tracking-based, and AI-based approaches.

Even though information in many languages other than English is quickly increasing, English is still playing the role of the lingua franca and being accounted for the largest proportion on the web. Therefore, it is necessary to investigate the key features and differences between "information searching behavior using mother tongue as a search language" and "information searching behavior using English as a search language" of users who are non-mother tongue speakers of English to acquire more diverse and abundant information. This study conducted the experiment on the web searching which is applied in concurrent think-aloud method to examine the information searching behavior and the cognitive process in Korean search and English search through the twenty-four undergraduate students at a private university in South Korea. Based on the qualitative data, this study applied the frequency analysis to web search pattern under search language. As a result, it is active, aggressive and independent information searching behavior in Korean search, while information searching behavior in English search is passive, submissive and dependent. In Korean search, the main features are the query formulation by extract and combine the terms from various sources such as users, tasks and system, the search range adjustment in diverse level, the smooth filtering of the item selection in search engine results pages, the exploration and comparison of many items and the browsing of the overall contents of web pages. Whereas, in English search, the main features are the query formulation by the terms principally extracted from task, the search range adjustment in limitative level, the item selection by rely on the relevance between the items such as categories or links, the repetitive exploring on same item, the browsing of partial contents of web pages and the frequent use of language support tools like dictionaries or translators.

As a way of identifying users' image needs for improved effectiveness of image search, there have been recent research approaches to examine contextual factors in image needs with multiple perspectives. In this line of research, this study examined a total of 70 unsuccessful image searches for the purpose of investigating users' image needs. In order to achieve the purpose of this study, in particular, the characteristics of image needs, contextual factors on image needs, and image queries were investigated. The findings of this study demonstrated that information needs from the failed image searches are categorized primarily into specific and general/nameable categories. More importantly, these information needs are embedded with multiple contextual factors, primarily, task purpose and use purpose. With an analysis of detailed use purposes for image, illustration use was found most in this data set. For query analysis, the type of unique/refined image query was revealed primarily. As the results of this study were found similar to the findings of previous studies, it is possible to characterize the image needs from the failed image searches. In addition, the findings of this study are expected to be useful to the design and service of image retrieval.
