In this study, LD construction cases of overseas libraries were analyzed with focus on published datasets, reused vocabulary, and interlinked external datasets, and based on the analysis results, basic data on LD construction plans of domestic libraries were obtained. As a result of the analysis of 21 library cases, overseas libraries have established a faithful authority LD and conducted new services using published LDs. To this end, overseas libraries collaborated with other libraries and cultural institutions within the region, within the country, and nationally under the leadership of the library, and based on this cooperation, a specialized dataset was published. Overseas libraries used Schema.org to increase the visibility of published LDs, and used BIBFRAME for subdivision of description to define various entities and build LDs based on the defined entities. Overseas libraries have utilized various defined entities to link related information, display results, browse, and download in bulk. Overseas libraries were interested in the continuous up-to-date of interlinked external datasets, and directly utilized external data to reinforce catalog information. In this study, based on the derived implications, points to be considered when issuing LDs by domestic libraries were proposed. The research results can be used as basic data when future domestic libraries plan LD services or upgrade existing services.

Photographic images of the Samseong-version (三省本: Korea's Treasure No. 758-1) and the Gongin-version (空印本: Korea's Treasure No. 758-2) of Nammyeongcheon Hwasangsong Jeungdoga (南明泉和尙頌證道歌: Nanmingquan Song Zhengdaoge) were compared and analyzed to investigate the differences between the two versions. According to a report in 2012 at the time of the designation of the Gongin-version as Korea's treasure, both versions were printed from the same woodblocks. The Gongin-version is presumed to be a later print than the Samseong-version. The two versions are very similar in format and shape of border lines and characters. It is difficult to determine the differences with the naked eye, even for experts. In this study, based on the printing characteristics observed from each version through image analysis, useful evidence to determine whether it was printed using the same or different woodblocks and the order of printing was collected. As a result of careful image comparison and analysis, we concluded that the Samseong- and the Gongin-version were printed from different woodblocks, or possibly different typesetting. It was difficult to agree with the content of the report that the Gongin-version was a later print than the Samseong-version. In addition, it was noted that the Gongin-version print has characteristics quite different from the typical characteristics of woodblock printing seen in the Samseong-version. Additional investigations and follow-up studies on the printing technology used for Gongin-version print and the timing of printing are recommended.

The passive surface wave method measures seismic signals from ambient noises or vibrations of natural phenomena without using an artificial source. Since passive sources are usually in lower frequencies than artificial ones being able to ensure the information on deeper geological structures, the passive surface wave method can investigate deeper geological structures. In the passive method, frequency dispersion curves are obtained after data acquisition, and the dispersion curves are analyzed by assuming 1D-layered earth, which is like the method of active surface wave survey. However, when computing dispersion curves, the passive method first obtains and analyzes coherence curves of received signals from a set of receivers based on spatial autocorrelation. In this review, we explain how passive surface wave methods measure signals, and make data processing and interpretation, before analyzing field application cases.

With the development of the virtual community, the benefits that IT technology provides to people in fields such as healthcare, industry, communication, and culture are increasing, and the quality of life is also improving. Accordingly, there are various malicious attacks targeting the developed network environment. Firewalls and intrusion detection systems exist to detect these attacks in advance, but there is a limit to detecting malicious attacks that are evolving day by day. In order to solve this problem, intrusion detection research using machine learning is being actively conducted, but false positives and false negatives are occurring due to imbalance of the learning dataset. In this paper, a Random Oversampling method is used to solve the unbalance problem of the UNSW-NB15 dataset used for network intrusion detection. And through experiments, we compared and analyzed the accuracy, precision, recall, F1-score, training and prediction time, and hardware resource consumption of the models. Based on this study using the Random Oversampling method, we develop a more efficient network intrusion detection model study using other methods and high-performance models that can solve the unbalanced data problem.

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.

This thesis investigates the meaning of a performer's energy taking into an account of the full bodily engagement as the flow of energy and/or psychophysical readiness focusing specifically on the significance of qualitative bodily transformation. In this contemporary era, the dominance of performer training and its approaches to acting/training has very frequently meant that how to play a character in a textual based approach by emphasizing on interpreting and impersonating the role as real as possible. In this sense, as a performer trainer, from my observation and research findings shows that it is common for the term energy is not to be motivated by what a performer's body needs within a specific moment in specific performance which they are working on. To address the problematic issues, this thesis begins by interrogating the practical meaning of transformation with addressing the principle and process of movement by means of the flow of energy on stage. For a performer, inhabiting/integrating his/her body and mind as oneness and/or unity means s/he sincerely encounter, confront, and therefore listen to his/her body in here and now. Because since the performer's physical appearance completely defined his/her psychological state, no one can play either the past or the future in the moment. In this manner, an appropriate use of energy synonymous with the flow of energy correspondence with the given time and space in which the performer's body informs and initiates movement as necessary action. To be precise, the performer's bodily movement either visible or invisible in a sense of training and rehearsal is perceived as attaining or achieving psychophysical involvement as the full body engagement which enable to make the event happen in the right moment. Here, this thesis argues that the significance of a performer's inner intensity reminds us of the necessity of qualitative transformation on which the performer could discover his/her own mode of awareness as well as a way his/her body function in the given circumstance. From this point of view, this research finding would advocates that the performer's body maintains in the field of energy flow where his/her conscious effort and/or mindfulness disappear. The performer's movement is a manifestation of the whole bodily engagement by means of being as real in that moment rather than representing reality.

At the time of discussing the 2022 revised curriculum, the demand for normalization of information education is increasing. This study was conducted on the case of the information curriculum for the upper elementary grades responding to such needs. For 14 6th grade students of Elementary School B in K Metropolitan City, 4 core areas of the information curriculum, including computing system, data, algorithm & programming, and digital culture, were covered through classes. Cooperative classes were conducted between students by using the cloud-based application according to the class. In addition, it was intended to supplement the curriculum by suggesting ideas for artificial intelligence education area, and to improve the density of research with additional investigation on foreign information education cases. However, the need for independent organization of the information curriculum was strongly confirmed in that the current curriculum for information classes lacked sufficient school hours and had to be operated in combination with other subjects in the form of a project for this case study. It is hoped that this study will serve as a small foundation for the establishment of the information curriculum for the upper elementary grades in the future.

The word library(図書館) is a Japanese translation of the Western library or Bibliothek in the mid-Meiji period. This word has been accepted in Chinese(图书馆), Taiwan(圖書館), Korea(도서관), and Vietnam(Dđồ thư quán), which are Chinese-speaking countries. If so, when and who first introduced the term library to Japan and China? In Japan, the enlightenment thinker Fukuzawa's 『Seiyo Jijo, 1866』 is regarded as the first document to introduce the Western library, and in China, the article published in 『Qing Yi Bao, 1896』 by the reformed thinker Liang Qichao referred to as the first example. Therefore, this study traced and demonstrated the time and person in which the word library appeared, focusing on modern dictionaries, books, translations, papers, and newspaper articles that were introduced in both countries. As a result, the theory of the introduction to Fukuzawa in 1866 is wrong because Western libraries are described in various terms in many diaries and dictionaries, including Motoki's 『An English Japanese Dictionary of the Spoken Language, 1814』. Also, in China, the theory of introduction of Liang Qichao in 1896 is not true because the term library first appeared in Ryu Jeong-dam's 『A Dictionary of Loan Words and Hybrid Words in Chinese, 1884』. In the same context, it is necessary to trace and argue the history of the first use of the term library in Korea and the name of the first library in Korea established by the Busan Branch of the Japan Hongdo Association in 1901.

The construction safety policy of Korea requires safety reviews at design stages, which affect the perceptions and attitudes of the workers toward safety. Despite this heightened social interest in safety, there is no related research in the field of landscape architecture. This study entails a review of the status of landscape construction accidents in Korea and an assessment of landscape engineers' perception of construction safety climate and safety behaviors. A survey of landscape constructors and designers was performed, and the obtained data were statistically analyzed. The results indicate the following: (1) More than half of the accidents which are registered in CSI occurred in apartment houses ordered by the private sector in the type of facility and planting works in the landscaping process; (2) Landscape designers were better aware of safety than landscape constructors. Among them, safety attitude, work risk, work participation, and work pressure were statistically significant; Apart from the statistical significance, landscape designers recognized the importance of safety highly but they tended to have a relatively low perception of specific safety behaviors. (3) Lastly, landscape constructors attributed less importance to safety review during the design stage compared to other items.
