Along with the 4th Industrial Revolution, the impact of "unmanned" is affecting all fields around the world, and in particular, in the military sector, "unmanned" is so important that it occupies a part of the main combat system. Recently, the South Korean military is facing a crisis due to the North Korea's UAV incident that invaded our airspace and descended to Seoul. In response, the South Korea military declared its willingness and countermeasures to capture and destroy North Korea's UAV. However, as the technological development of UAV continues and the utilization plan is expanding, the countermeasures for UAV at the current level can be useless. Also, the threat from North Korea is not just UAV. North Korea has practically a nuclear power and is set to conduct its seventh nuclear test, and its missile technology is also being advanced, with 38 arounds of 67 missile tests conducted in 2022 alone. It is also developing five key strategic weapons that can pose a fatal threat to Korea, and North Korea's strong conventional forces are located around the NLL(Northern Limit Line), and the port of Long Range Artillery is facing the Seoul metropolitan area. It is important to respond to North Korea's UAV threats, which are now receiving much attention, but it will be necessary to comprehensively analyze and clearly prioritize North Korea's threats and use a limited budget to respond to them.

With the fourth industrial revolution and the arrival of the New Normal era due to Corona, the importance of Non-contact technologies such as artificial intelligence and big data research has been increasing. Convergent research is being conducted in earnest to keep up with these research trends, but not many studies have been conducted in the area of nuclear research using artificial intelligence and big data-related technologies such as natural language processing and text mining analysis. This study was conducted to confirm the applicability of data science analysis techniques to the field of nuclear research. Furthermore, the study of identifying trends in nuclear spent fuel recognition is critical in terms of being able to determine directions to nuclear industry policies and respond in advance to changes in industrial policies. For those reasons, this study conducted a media trend analysis of pyroprocessing, a spent nuclear fuel treatment technology. We objectively analyze changes in media perception of spent nuclear fuel dry treatment techniques by applying text mining analysis techniques. Text data specializing in Naver's web news articles, including the keywords "Pyroprocessing" and "Sodium Cooled Reactor," were collected through Python code to identify changes in perception over time. The analysis period was set from 2007 to 2020, when the first article was published, and detailed and multi-layered analysis of text data was carried out through analysis methods such as word cloud writing based on frequency analysis, TF-IDF and degree centrality calculation. Analysis of the frequency of the keyword showed that there was a change in media perception of spent nuclear fuel dry treatment technology in the mid-2010s, which was influenced by the Gyeongju earthquake in 2016 and the implementation of the new government's energy conversion policy in 2017. Therefore, trend analysis was conducted based on the corresponding time period, and word frequency analysis, TF-IDF, degree centrality values, and semantic network graphs were derived. Studies show that before the 2010s, media perception of spent nuclear fuel dry treatment technology was diplomatic and positive. However, over time, the frequency of keywords such as "safety", "reexamination", "disposal", and "disassembly" has increased, indicating that the sustainability of spent nuclear fuel dry treatment technology is being seriously considered. It was confirmed that social awareness also changed as spent nuclear fuel dry treatment technology, which was recognized as a political and diplomatic technology, became ambiguous due to changes in domestic policy. This means that domestic policy changes such as nuclear power policy have a greater impact on media perceptions than issues of "spent nuclear fuel processing technology" itself. This seems to be because nuclear policy is a socially more discussed and public-friendly topic than spent nuclear fuel. Therefore, in order to improve social awareness of spent nuclear fuel processing technology, it would be necessary to provide sufficient information about this, and linking it to nuclear policy issues would also be a good idea. In addition, the study highlighted the importance of social science research in nuclear power. It is necessary to apply the social sciences sector widely to the nuclear engineering sector, and considering national policy changes, we could confirm that the nuclear industry would be sustainable. However, this study has limitations that it has applied big data analysis methods only to detailed research areas such as "Pyroprocessing," a spent nuclear fuel dry processing technology. Furthermore, there was no clear basis for the cause of the change in social perception, and only news articles were analyzed to determine social perception. Considering future comments, it is expected that more reliable results will be produced and efficiently used in the field of nuclear policy research if a media trend analysis study on nuclear power is conducted. Recently, the development of uncontact-related technologies such as artificial intelligence and big data research is accelerating in the wake of the recent arrival of the New Normal era caused by corona. Convergence research is being conducted in earnest in various research fields to follow these research trends, but not many studies have been conducted in the nuclear field with artificial intelligence and big data-related technologies such as natural language processing and text mining analysis. The academic significance of this study is that it was possible to confirm the applicability of data science analysis technology in the field of nuclear research. Furthermore, due to the impact of current government energy policies such as nuclear power plant reductions, re-evaluation of spent fuel treatment technology research is undertaken, and key keyword analysis in the field can contribute to future research orientation. It is important to consider the views of others outside, not just the safety technology and engineering integrity of nuclear power, and further reconsider whether it is appropriate to discuss nuclear engineering technology internally. In addition, if multidisciplinary research on nuclear power is carried out, reasonable alternatives can be prepared to maintain the nuclear industry.

Efforts to identify the public's perception of social welfare as an academic discipline have never been conducted in Korea since the establishment of social welfare department in 1947 at Ewha Womans University. Such efforts are very meaningful in identifying directions and tasks to strengthen Korean social welfare as well as in clarifying and promoting our understanding concerning status of the academic discipline. This study attempts to explore and describe the degree of the public's perception in Korea with analyzing data surveyed in 2004 by our interdisciplinary research team. This study develops and uses a questionnaire having a Likert scale format that is composed of 8 points and measures the public's perception in the following dimensions: (1) personal interests on academic discipline; (2) contribution of academic discipline; (3) prospect of academic discipline; (4) importance of academic discipline; (5) expertise of academic discipline; and (6) personal knowledge on academic discipline. To avoid social desirability and promote objectivity with comparative measurement, this study selects ten representative academic disciplines as follows: medicine; physics; biology; social welfare; economics; psychology; sociology; political science; library science; and communication & journalism. This study attempts to identify (1) the degree of the public's perception on ten academic disciplines; (2) the position of social welfare by comparing it with each academic discipline and by comparing mean of social welfare with overall mean of six social science disciplines in the six dimensions; (3) the differences in the public's perceptions of social welfare on six dimensions by the respondents' status factor(high school students, college and graduate students, and citizens) and gender factor by using MANCOVA, and (4) the differences in the public's perceptions of social welfare on six dimensions by major factor(social welfare, social science majors, and natural science majors) and gender factor of college and graduate school students by using MANCOVA. The results of data analysis are as follows: (1) while the 3,319 respondents gave relatively high rating on natural sciences in the dimensions of contribution and expertise, they did the same on social sciences in the dimensions of personal interests and personal knowledge; (2) in overall comparisons, while the 3,319 respondents gave relatively high rating on social welfare in the dimensions of contribution, prospect and importance, they gave the lowest rating on the expertise of social welfare; (3) in the comparisons with social science disciplines, while the 3,319 respondents gave relatively high rating on social welfare in the dimensions of contribution, prospect and importance, they gave the lowest rating on the expertise of social welfare; (4) when analyzing all the respondents, there were differences in the vector of personal interests, contribution, prospect, importance, expertise, and personal knowledge by status factor, gender factor, and interaction effect factor; and (5) when analyzing only the respondents in college and graduate schools, there were differences in the vector of personal interests, contribution, prospect, importance, expertise, and personal knowledge by only major factor and gender factor. The results provide empirical backgrounds for discussing current image, status and major characteristics of social welfare as a discipline in Korea. Indeed, this study provides new meaningful and thoughtful guide for further investigation on the topic. In addition, contributing to clarifying and broadening our understandings about the public's perception on social welfare in Korea, this study discusses the tasks for dealing with expertise issue that is the most vulnerable issue of Korean social welfare discipline and research directions to strengthen and promote social welfare discipline in Korea.

With a view to providing a high-quality policy information service beyond the existing national task service of the national policy information portal (POINT) of the National Library of Korea Sejong, it would be necessary to effectively provide the policy data needed for the implementation of the new national tasks. Accordingly, in this study, an attempt has been made to find a way to connect and develop the BRM-based national tasks and the policy information contents. Towards this end, first, the types of national tasks and the contents of each field and area of the government function's classification system were analyzed, with a focus placed on the 120 national tasks of the new administration. Furthermore, by comparing and analyzing the national tasks of the previous administration and the current information, the contents ought to be reflected for the development of contents related to the national tasks identified. Second, the method for linking and collecting the policy information was sought based on the analysis of the current status of policy information and the national information portal. As a result of the study, first, examining the 1st stage BRM of the national tasks, it turned out that there were 21 tasks for social welfare, 14 for unification and diplomacy, 17 for small and medium-sized businesses in industry and trade, 12 for general public administration, 8 for the economy, taxation and finance, 6 for culture, sports and tourism, science and technology, and education each, 5 for communication, public order and safety each, 4 for health, transportation and logistics, and environment each, 3 for agriculture and forestry, 2 for national defense and regional development each, and 1 for maritime and fisheries each, among others. As for the new administration, it is apparent that science technology and IT are important, and hence, it is necessary to consider such when developing the information services for the core national tasks. Second, to link the database with external organizations, it would be necessary to form a linked operation council, link and collect the information on the national tasks, and link and provide the national task-related information for the POINTs.

The 20th National Congress of the Chinese Communist Party (hereafter referred to as "the 20th National Congress") was under the global spotlight long before it was held for seven days from 16 to 22 October 2022. People wondered whether Xi Jinping would secure a third term as China's leader or whether he would lay the foundations to be in power forever during the third term. In Korea, the press and media questioned whether the event would become the "crowning of Emperor Xi (Xi Huangdi)," whose power rivaled that of the first emperor in China, Shi Hunagdi, and featured the scene where Hu Jintao was forced to leave the venue during the Congress. On the other hand, many Korean academics focused more on how Xi would organize the Politburo and its Standing Committee and whether the outline of his heirs would appear during the event. This tendency in academia in turn worsened the media's concerns. This paper presents a quantitative analysis of the 20th National Congress Report, as opposed to an analysis of Xi's political intentions at the event. The National Congress Report outlines the Party's visions, goals, and strategies for the next five years in politics, economy, society, culture, foreign affairs, and relationship with Taiwan. The authoritative document is rich in narrative and logic and deserves academic study. This research analyzes the 18th, 19th, and 20th Reports by identifying their keywords and regular expressions and checking their frequency and percentage through text-mining methods. This approach enables the quantification and visualization of the significant changes in the Party's sovereign vision over the fifteen years of Xi's rule from 2013 to 2027.

The idea of creating a new International Space Agency (ISA) is only my academic and practical opinion. It is necessary for us to establish ISA as an international organization for the efficient and rapid exploitation of natural resources in the moon, Mars and other celestial bodies. The establishment of ISA as a new international regime is based on the Article 11, 5 and Article 18 of the 1979 Moon Agreement. In order to establish as a preliminary procedure, it needs to make a "Draft for the Convention on the Establishment of an International Space Agency" among the space-faring countries. In this paper, I was examined the domestic space legislation in the United States, Luxembourg, European Space Agency, China, Japan, the Republic of Korea as well as space exploration and planning of the moons, Mars, Asteroids, Venus, Jupiter, Saturn, Titan and Other Celestial Bodies. The creation of an ISA would lead to a strengthening of the cooperation needed essentially by the developed countries towards joint and cooperative undertakings in space and would act as a catalyst for the space exploration and exploitation of the moon, Mars and other celestial bodies. It will be managed effectively and centrally the exploitation and exploitation of space the natural resources, technology, manpower and finances as an independent organization in order to get the benefit of the space developed countries by ISA. It is desirable and necessary for us to establish ISA in order to promote cooperation in space policy, law, science technology and industry among the space developed countries in the near future. The establishment of the ISA will be promoted the international cooperation among the space-faring countries in exploration and exploitations of the natural resources in the moon and other celestial bodies. I would propose the "Draft for the Convention for the Establishment of an International Space Agency." in refering the "Convention for the Establishment of a European Space Agency." This "Draft for the Convention Convention for the Establishment of an ISA" must pass the abovementioned "Draft for the Convention" by two-third majority of Diplomatic Conference in the UNCOPUOS. Finally, a very important point is need that a political drive at the highest level and a solemn statement by heads of state of the space devloped countries including the United Nations for the space exploitation of the medium and long term. It should be noted that this political drive will be necessary not only to set up the organization, but also during a subsequent period. It is desirable and necessary for us to establish the ISA in order to develop the space industry, to strengthen friendly relations and to promote research cooperation among the space-faring countries based on the new ideology and creative ideas. If the heads of the superpowers including the United Nations will be agreed to establish ISA at a summit conference, 1 am sure that it is possible to establish an ISA in the near future.

The purpose of this research is to fill the vacuum created by the tendency of bias towards China among the curators of Korean museums who plan exhibitions focusing on Balhae, and to share with researchers in the countries concerned various supplementary research materials that could deepen their understanding of the history of Balhae. These materials are based on analyses of the details of exhibitions about Balhae held in a particular Russian museum and the characteristics of and changes in the museum's operational policy. Thus, this research focuses mainly on the permanent and special exhibitions held by the Far East History Museum and Reserve, whose collection represents the archaeological achievements of Russia regarding the history of Balhae. The first part of the research focuses on the layout of the exhibitions presented by the museum and the museum's operational policy. It reveals that the museum's permanent exhibitions follow a diachronic arrangement of the local history, while the first and second special exhibitions featured exhibits that were selected from the collections of the Russian Academy of Sciences and arranged according to specific themes. It also examines the museum's policy for operating the exhibitions, focusing on the operational rules, the human resources deployed to run them, and the related educational and PR programs. The second part of the research examines such issues as local politics, economy, education and culture related to the exhibitions on Balhae's history, and connects them to the background and development of the exhibitions. This study reveals that the permanent exhibitions were intended to promote historical awareness of the local area by museum visitors, particularly those who visited the exhibitions while the city was hosting important events such as international summits. It also reveals that the museum's first special exhibition led to the promotion of Korea-Russia cooperation on exchanges in the fields of culture and tourism, whereas the second special exhibition involved no PR efforts or related events, which was probably due to the changes that have occurred in the relationship between Russia and its neighboring countries since then. The final part of the study focuses on the characteristic features of the exhibition narratives, and compares school textbooks on local history and history books for general readers with the contents of the exhibitions. The analysis of the narratives based on the development of time shows that the history of the Mohe (or Malgal) tribes has been combined with that of Balhae, while they are treated separately in school textbooks. As regards political history, the narrative was largely focused on officials in Balhae's central government rather than on Mohe warriors in the border areas. The maps of Balhae presented in the exhibitions highlight the importance of accumulating empirical data. As for the exhibition of material cultures, this study suggests that the museums should obtain more archaeological floral and faunal remains related with agriculture and hunting. It also points out that the narrative on the theme of foreign relations deals with the archaeological relics of Unified Silla together with those of the Turkic tribes. As for the theme of philosophy and culture, the narrative focused on the state ceremonies and rituals of Goguryeo, a theme that has attracted little attention among Korean academic circles and which consequently requires further study. In conclusion, this study is meaningful in that it suggests a number of research topics regarding the development of exhibitions and exhibition narratives about the history of Balhae by a prestigious Russian museum that specializes in this subject.
