Suk Dang Kim Sangjeong (1722-1788) was one of the Big Three Noron literati of the mid-18th century, and is an author worth taking note of in that he expressed the duty to pursue the Qin-Han gomoon-ron (古文論) more clearly and radically than anyone else. The literary debates that unfolded in the letters he exchanged with Ahn Doje (安道濟) and Sin Daejeon (申大傳) are the clues that may explain the continual development of Qin-Han gomoon-ron within Joseon. His gomoon-ron is a self-reflection of the Dang-Song gomoon-ron that continued as tradition in the Noron literati after Kim Changhyeop (金昌協), and also reflects his literary and periodical confidence. At the same time, he also makes a distinction with Qin-Han gomoon-ron set forth by the Seven Masters literature from the Ming Dynasty (前後七子) in that he takes precautions against plagiarism and emulation. It has rarely been shown that his sentences plagiarize and excessively cite the classics, or that he abstrusely elaborates sentences. He sorted through things of value worth recording and cleanly reenacted them based on the scenes and conversations, further, delivered applicable normative lessons through allegoric writing. This may be discussed as the portions that are possessed by the Qin-Han gomoon-ron that he pursued, and particularly that have the esthetic and contact point of historical prose. Kim Sangjeong's writing pursued the Qin-Han gomoon-ron of a prior era, and though distinguishable from authors of difficult writings, possesses unique characteristics that make it distinct from the Dang-Song gomoon-ron that focuses on argument. The direction of Kim Sangjeong's antiquarianism seeks after imperial loyalty, and is mutually intelligible with the artistic discourse of the Noron Cheongryu literati such as Lee Yunyeong, Kim Sangsuk, Lee Insang, and Hong Naksun who preferred archaeological finds and classical prose. While their literary tastes are a reflection of their conservative worldviews, they may also have been utilized as a foundation supporting their lives which were devoted to literature.

This thesis aims at examining the world of pacification in Zhuzi(朱子)'s Daxuezhangju("大學章句"). He said that it was necessary to understand others through Xiejuzhidao(?矩之道) as Shu(恕) for the completion of pacification. The Shu(恕) in it is not an active one but a passive one. It's because one doesn't need to be very active in order to realize the world of pacification. Too much initiative can rather cause loss. Then Shijing("詩經") was quoted, all of which told about that it should be properly followed to understand others through Xiejuzhidao(?矩之道) as Shu(恕). Zhuzi(朱子) explains the reasons for frugality. The modern society is a capitalistic. Yet, not all kinds of capitalism are right. Think about the trash island on the Pacific Ocean. In Daxuezhangju("大學章句"), frugality is suggested as a good way. As the way of frugality, the most important goal of a king is to get rid of the vassals who exploit people. And at the last part, there's warning that petty and crafty men should be appointed. It says that even when everything has been fulfilled, if a petty and crafty man is appointed to take charge of it, the nation can be lost, so a king must give noble men important positions. The world of pacification in Daxuezhangju("大學章句") has not been studied as much as Gewuzhizhi(格物致知). This thesis is expected to offer the chance for more researches on it.

Research in various academic fields using network analysis techniques has been conducted and grown. This study performed bibliographical analysis and content analysis on a total of 2,187 network analysis papers published in journals from 2003 to 2021. The results showed that the fields of Pedagogy, Interdisciplinary Research, Computer Science, Library and Information Science, Public Administration, and Business Administration were higher in terms of the number of research papers. From the perspective of journal, mega-journals were indicated as the most productive journals. However, when looking at the impact based on the number of citations, the strength of Public Administration, Library and Information Science, and Pedagogy is clearly revealed. The results of the analysis by authors can also confirm the higher impact of Journalism, Public Administration Science, and Library and Information Science. Of the 1,537 authors identified, very few authors are active in research, confirming the need to expand the researcher base. The results of content analysis showed that the weighted and non-directional network was the most common network type with using the research papers as a data set. Generally nodes are expressed as words and links are expressed as relationship. For network analysis, the use of KrKwic, UCINET, NetMiner, and NetDraw is the most prominent.

The earthquakes are the natural disasters that can cause the most serious damage to civil structures. Therefore, various studies are being conducted to secure the safety of structures against earthquakes. Most studies on the safety or mechanism of civil structures during earthquakes are being conducted based on lab scale test, because real structure tests are impossible when considering the scale of civil structures. The scaling factor proposed by Iai is mainly cited, but when applying the scaling factor proposed by Iai, there are many difficulties in selecting the structural members necessary for the production of the lab scale model. This is because when applying the scaling factor proposed by Iai, the scaling factor must be applied to the elastic modulus, which is the material property of the structure. Therefore, a new method based on Iai's 's similarity law for determining scale factor is applied in this study where the material property of real structure is same as that of lab-scale model. Through the results of this study, it is considered that the characteristics of the structure calculated through the lab scale model test can more accurately reflect the characteristics of the real structure.

In this study, a novel antiviral coating method for the air filtration system of subway station was investigated. Using dry aerosol coating process, we developed a high-performance antiviral air filter with spark discharger and carbon brush type ionizer. Silver nanoparticles were produced by a spark discharge generation system with ion injection system and were used as antiviral agents coated onto a medium grade air filter. The pressure drop, filtration efficiency, and antiviral ability of the filter against aerosolized MS2 virus particles as a surrogate of SARS-CoV-2 virus were tested with dust contamination. Dust contamination caused the increase of the filtration efficiency and pressure drop, while the antiviral agents (in this study, silver nanoparticles) coating did not have any significant effect on the filtration efficiency and pressure drop. Using these properties, we suggested a novel method to maximize the antiviral performance of the antiviral air filter that was contaminated by dust particles. Moreover theoretical analysis of antiviral ability with dust contamination and re-coated antiviral agents was carried out using a mathematical model to calculate the time-dependent antiviral effect of the filter under actual conditions of subway station. Our model can be used to apply on antiviral air filtration system of subway station for prevention of pandemic diffusion, and predict the life cycle of an antiviral filter.

The aim of this study was to subdivide and present the units and the standards of knowledge integration in creating the students' integrated knowledge from content knowledge in college writing classes. For these, it analyzed three typical writing textbooks being used in colleges and examined the ways of presentation on forming integrated knowledge by text qualitative analysis methods. The analysis procedure and the presentation followed Creswell's spiral analysis model It is a method model which repeats the procedure from material collection and analysis to presentation circularly. This examination illustrates three dimensions of the units in forming content knowledge. Also, it suggested those should be all treated for the more systematic education: the units of the whole text, the paragraphs, and the sentences. In the next chapter, the standards and contents of knowledge integration were suggested in each process. For the process of knowledge selection, the suitability and the contradictoriness between the text materials and author's thesis were proposed as the standards and contents. For the process of organization and integration, the corresponsive integration, contradictive integration, background integration, synthetic integration were suggested. Finally the procedure knowledge such as correct expression and spelling, source indication were shown for the process of expression and citation. Furthermore, it showed, in terms of expression, the process of paraphrasing frequently practiced in writing textbooks needs to be exercised in the three dimensions including summarization, connection, and interpretation(or transformation). This result, however, calls for the further study about the subdividing processes to enhance the adequateness to writing textbooks in the level of universities and for a more refined syllabus on the systematic knowledge integration. Accordingly, it suggested the tasks mentioned above for further study.

Airworthiness certification is critical, in ensuring the flight safety of military aircraft for development tests and production operations. The MIL-HDBK-516C, latest airworthiness certification document, handles the field of flying qualities in Chapter 6 (flight technology), and refers to specific chapters of MIL-STD-1797B, which is the specification document for developing military aircraft. Since the MIL-STD-1797B released in 2006 by the U.S. Department of Defense is not disclosed to other countries, the Chapter 6 (flight technology) of MIL-HDBK-516B Expanded, the former certification standards pursuant to flying qualities, has to be applied to military aircraft being developed in the Republic of Korea. However the requirements of Chapter 6 of MIL-HDBK-516B Expanded comprise unclear sentences, because of contents from various development specifications. Also, clarification is needed in that the same requirements have to be verified in different criteria. In this paper, the results of this study present an effective verification method, for acquiring the airworthiness certification in field of flying qualities based on MIL-HDBK-516B Expanded.

In this work, virion concentration and its dose changes by HVAC and air cleaners were estimated in a subway station platform to control airborne infection of SARS-CoV-2. Collection efficiencies with particle size were measured for the air filter equipped in a HVAC in one subway station in Daejeon. Indoor PM_2.5 changes according to outdoor PM_2.5 with time were also measured to estimate air infiltration rate in the subway station platform. When infected persons generate virions by 10⁴, 10⁵, 10⁶, 3 × 10⁶ and 5 × 10⁶ h^-1 in a 2,400 m³ volume platform, the concentration and dose were estimated as 9, 92, 275 and 458 virions/m³ and 4, 43, 130 and 217 virions after 1 hour exposure, respectively. The concentration and dose were reduced by 70%, and 64%, respectively by operations of both HVAC (with a flow rate of 16,000 m³/h, MERV 11) and ten air cleaners(with total CADR 10,740 m³/h) compared to those without operation of both HVAC and air cleaners. However, virion dose in the platform was estimated to be too low at the general conditions due to a large space, a high air infiltration (3 h^-1) and a short residence time (usually < 10 mins) in the platform irrespective of the operations of HVAC or air cleaners. HVAC with filters and air cleaners would be more necessary in the concourse or shopping areas in the subway stations to reduce the infection dose from a few hundred to several tens virions in a hour.

This study will analyze the meaning of the signifiant, which occupies an absolute position in Lacanian psychoanalysis, and will prove the slip of meaning and signification that are accompanied together at the same time when the signifiant was utter through the subject. By directly citing the part where Lacan explained signification in his seminars and Écrits, I would like to examine how signifiant is carried out in everyday conversation. In addition, the dialogue that takes place in our discourse has the purposefulness and groundless purposelessness of the signifiant. Understanding this purpose is the core part that Lacanian psychoanalysis aims to pursue, and it discovers the cracks of the hidden meaning in the relationship between the signifiant and the signifiant connected to the next, presenting that the signifiant which arouses unrelenting fantasy of the subject is the practical ruler of body and mind. This thesis is aimed to present the above points mentioned above, and as an alternative to overcome the limitations of the signifiant, the ruler in discourse, this study would like to suggest the autonomy as a subject resisting against "Where it was, I must come into being," pursued by Lacan psychoanalysis.
