The purpose of this study is to propose AET (Augmented and Extended Topics), a novel method of synthesizing both LDA and BERTopic results, and to analyze the recently published LIS articles as an experimental approach. To achieve the purpose of this study, 55,442 abstracts from 85 LIS journals within the WoS database, which spans from January 2001 to October 2021, were analyzed. AET first constructs a WORD2VEC-based cosine similarity matrix between LDA and BERTopic results, extracts AT (Augmented Topics) by repeating the matrix reordering and segmentation procedures as long as their semantic relations are still valid, and finally determines ET (Extended Topics) by removing any LDA related residual subtopics from the matrix and ordering the rest of them by F₁ (BERTopic topic size rank, Inverse cosine similarity rank). AET, by comparing with the baseline LDA result, shows that AT has effectively concretized the original LDA topic model and ET has discovered new meaningful topics that LDA didn't. When it comes to the qualitative performance evaluation, AT performs better than LDA while ET shows similar performances except in a few cases.

The ultimate Wastes generated after being treated safely and properly were land-filled in Wha Sung Treatment Plant, that of specific hazardous Wastes. There are three kinds of wastes being landfilled, which are sludges, ashes, and solidificated wastes with cement. This research scrutinizes the variations of leachate which originated from landfilled wastes amount to 30,000 ton with analizing the constituent, pH and concentration of wastes once per month since september, 1987. Now, we have some conclusions as followings; 1. The longer retention time of wastes in landfill site and the more quantity of filling-up, the closer pH of leachate to alkalinity. 2. As the quantity of copper and its compounds is over 90 percent of constituents loundfilled wastes, so the copper of leachate goes above treatment criteria. 3. There lis relationship between pH of leachate and eruption of copper and its compounds. The higher pH of leachate, the more secured copper and its compounds. So, we learn that solidificated wastes with cement is more secured than sludges and ashes. 4. The pH and concentration of copper in leachate is low in July and August, this is passing phenomenon which diluted by rainfall in rainy days. 5. The quantities of cadmium and lead of leachate was not over the treatment criteria.

Higher educational institutions face an increasing demand for developing a renewed set of competencies of college students who will live in the knowledge-based society. However, relatively little is known about what constitutes the core competencies that college students need to develop and how we can improve them. Nine categories of core competencies required for college graduates were drawn from the previous research and examples of core competencies developed by other institutions. They are analytic thinking skills, problem-solving skills, communicating skills, collaborative working skills, and etc. A reading guidance course for strengthening core competencies, developed based on the teaching and learning methods was adapted to students of LIS for one semester. Implications of these and related findings are discussed.

User education in academic libraries can be traced back to the beginning of the education for librarianship in late 19th century. Since then, perspectives in library user education and the perceptions of researchers and practitioners have changed due to new technologies. Recent literature in this field illustrates wide variety of concerns and issues of user education in academic libraries. This paper attempts to highlight such issues and perceptions regrading the subject. It suggests that some fundamental features of LIS education require attention. Suggestions are outlined along with the strong recommendations in terms of the importance of critical thinking and reading, user education as a tool of library promotion, and the politics of academic library user education.

In response to the changing needs of users and library services, there is a need to develop a library information science curriculum that reflects such change and to foster competent librarians. Recent studies abroad have emphasized the need for librarians who can apply design thinking methods which is a problem-solving methodology that expansively explores various alternatives and derives results, in response to recent changes and problems occurring in libraries. In this study, in order to understand how design thinking methods can be taught and to understand the perceptions of the students and librarians involved in the course, a case study is conducted of a class that applied design thinking methods and students and librarians have been interviewed who had experience participating in the class. By reflecting on the needs of students and librarians', this study explored new directions of what forms courses can take for future librarians. Based on the results of the analysis, among the different characteristics of design thinking, the value of cooperation, problem-solving ability, flexibility and iteration of design characteristics was considered as the value of a class for LIS students and librarians where design thinking methods were applied. From the findings, the research suggests future directions of creating more structured courses that involve an element of design thinking.

Thisstudy demonstratessoil moisture and evapotranspiration performance using Korea Land Data Assimilation System (KLDAS) under Korea Land Information System (KLIS). Spin-up was repeated 8 times in 2018. In addition, low-resolution and high-resolution meteorological data were generated using meteorological data observed by Korea Meteorological Administration (KMA), Rural Development Administration (RDA), Korea Rural Community Corporation (KRC), Korea Hydro & Nuclear Power Co.,Ltd. (KHNP), Korea Water Resources Corporation (K-water), and Ministry of Environment (ME), and applied to KLDAS. And, to confirm the degree of accuracy improvement of Korea Low spatial resolution (hereafter, K-Low; 0.125°) and Korea High spatial resolution (hereafter, K-High; 0.01°), soil moisture and evapotranspiration to which Modern-Era Retrospective analysis for Research and Applications, version 2 (MERRA-2) and ASOS-Spatial (ASOS-S) used in the previous study were applied were evaluated together. As a result, optimization of the initial boundary condition requires 2 time (58 point), 3 time (6 point), and 6 time (3 point) spin-up for soil moisture. In the case of evapotranspiration, 1 time (58 point) and 2 time (58 point) spin-ups are required. In the case of soil moisture to which MERRA-2, ASOS-S, K-Low, and K-High were applied, the mean of R² were 0.615, 0.601, 0.594, and 0.664, respectively, and in the case of evapotranspiration, the mean of R² were 0.531, 0.495, 0.656, and 0.677, respectively, indicating the accuracy of K-High was rated as the highest. The accuracy of KLDAS can be improved by securing a large number of ground observation data through the results of this study and generating high-resolution grid-type meteorological data. However, if the meteorological condition at each point is not sufficiently taken into account when converting the point data into a grid, the accuracy is rather lowered. For a further study, it is expected that higher quality data can be produced by generating and applying grid-type meteorological data using the parameter setting of IDW or other interpolation techniques.

This paper grasps about various features of the coauthorship network based on the co-author frequency in the Korean LIS Research Community. This issue includes many topics such as changable aspects of coauthorship network, properties of higher cooperative authors groups. This work is mostly analyzed through a bibliographic analysis of articles which is published from 2000 to 2009(10 years) in Korean Library & Information Science major four journals. The results show three major implications. 1) There is a various structural changes of coauthorship network on the change of the co-author frequency. 2) There are 21 research pairs in the higher cooperative authors groups with the co-author frequency more than five. 3) There seems that any subjective relations between the articles which is produced by 21 research pairs were not clearly presents.
