The Jija Chongtong Gun, owned by Seokdang Museum of Dong-A University, is a tubedstyle heavy weapon of the battlefield in the mid-Joseon Dynasty and is the second largest firearm after Cheonja Chongtong. The original surface color of the Jija Chongtong Gun was obscured by foreign substances and therefore it was judged that its condition requires the conservation treatment. For stable conservation treatment, gamma ray and X-ray non-destructive transmission surveys was conducted to determine the internal structure and conservation condition. And the component analysis on the material components and surface contaminants of Jija Chongtong Gun was conducted by utilizing the p-XRF component analysis, SEM-EDS component analysis, and XRD analysis. As a result of the gamma-ray and X-ray non-destructive transmission investigation, a large amount of air bubbles was observed inside Jija Chongtong Gun, and the part that appeared to be a chaplet by visual observation was not identified. As a result of gamma-ray and p-XRF component analysis, it was confirmed that Jija Chongtong Gun was bronze made of copper (Cu), tin (Sn), and lead (Pb) alloy. As a result of surface analysis of foreign substances using SEM-EDS, it was confirmed that the main components of white foreign substances were calcium (Ca), sulfur (S), and titanium (Ti). Titanium was presumed to be titanium dioxide (TiO₂), the main component of white correction fluid. The red foreign substance was confirmed to contain barium (Ba) as its main ingredient, and was presumed to be barium sulfate (BaSO₄), an extender pigment in paint. White and red contaminants, mainly composed of titanium and barium, are presumed to have been deposited on the surface in recent years. The yellow foreign substances were confirmed to be aluminum (Al) and silicon (Si), and were presumed to have originated from soil components. As a result of SEM-EDS and XRD component analysis, the white foreign substance was confirmed to be gypsum (CaS). Based on the results of component analysis, surface impurities were removed, stabilization treatment, and strengthening treatment were performed. During the conservation process, unknown inscriptions Woo (右), Byeong (兵), Sang (上), and Yi (二) were discovered through a portable microscope and precise 3D scanning. In addition, the carving method, depth, and width of the inscription were measured. Woo Byeong Sang is located above Happo Fortress in Changwon, and Yi can be identified as the second hill.

This essay seeks to answer the question of how best to understand Korean new religious movements (KNRMs). KNRMs have the characteristics of folk religion, ethno-religion, or popular religion. KNRMs are products of the national consciousness promoted by Korean society during the Late Joseon Dynasty at the turning point of modern Yi-Jing Studies. From the perspective of social evolutionary theory of developmental history, during that period, Joseon (Korea), like China, was faced with a double-edged sword consisting of the strength of tradition and the upheaval of modernity. If the strength of tradition depended on the Yi-Jing Studies to promote national enlightenment toward anti-imperialist aims, then it was equally the case that modernity depended on the sense of urgency to guide the people to secure livelihoods and edification regarding anti-feudalism. In this essay, the KNRMs that appeared during this transition period of Yi-Jing Studies will be a significant focus, and the worldview of Daesoon Thought will be the main focus. As one of the central topics, intensive discussion will be dedicated to the issue of the nature of pre-experientialism (先驗主義) which characterized the Great Opening (開闢). The principles of Daesoon Thought have a religious dimension of realistic awareness that guides the people's lives and edifies them. The process of the Great Opening aims to secure an ontological clock that tracks the Great Itineration of the world toward Daesoon Truth. This in turn as a process establishes the epistemological world of the Reordering Works of Heaven and Earth (天地公事) and reaches the axiological boundary of the future world. The links among the Three Realms is characterized by a pre-experientialist line that experiences the space-time nature of the universe as the Great Opening of the Later World (後天) within the framework of Heaven and Earth. Throughout this course, humans look to enjoy the infinite vitality of the universe from within their own finite vitality. Therefore, Daesoon Thought can overcome perceived reality through pre-experientialist channels such as the Great Opening of the Later World and aim for a state of self-awareness such as the Earthly Paradise. This is an attempt to participate and practice in the actual world rather than pursuing a world of transcendental ideas, and therefore, it tends to be proactive in the world rather than exhibit a passive tendency to be worldliness. In conclusion, the truth of Daesoon Thought, which is characterized by the Great Opening of the Later World, contains a future-oriented outlook that longs for a Nextopia full of hope and promise rather than idealistic fancy towards a Utopia or well-founded dread and disdain towards Dystopia.

This paper investigated the major history and reality of iconological composition for Jagyeongjeon Hall's flowered wall in Gyeongbokgung Palace, which was controversial in terms of preservation and management of cultural heritage. While analyzing the moment and cause of the flowered wall's renovation as it is now, modified or disappeared patterns were identified, and meaningfully misinterpreted congratulatory phrases were reviewed. The research results can be used as meaningful basic data when discussions are made for the restoration of the wall in the future. Jagyeongjeon Hall's flowered wall has reached the present day with large and small changes, but the inflection point that had a significant impact was the Joseon Expo (朝鮮博覽會) held at Gyeongbokgung Palace in 1929. This is because the wall that remained in the Jagyeongjeon Hall area was demolished to build an exhibition hall while preparing for the expo, and it was restored after the end of the event. It is highly likely that the modification or disappearance of the patterns constituting Jagyeongjeon Hall's flowered wall was also due to the restoration process carried out after the expo. There is a view that was transformed into its current state in the process of repair work carried out after the Korean War, but it is difficult to find any meaningful circumstances and evidence. Currently, character patterns known as 'Seongnidori(聖人道理)' are arranged on the inner wall of the section from Gyeongdomun Gate(擎桃門) to Yeogangmun Gate(如岡門), but considering the design form and example, it can be read as 'Seongjasinson(聖子神孫)'. The inner wall of the section from Yeogangmun Gate to Yeonsumun Gate(燕壽門) was originally made in the form of a flowered wall, and the phrases presumed to be 'Gyegyeseungseung(繼繼繩繩)' and 'Cheonse(千世)' were arranged. In the case of the section from Yeonsumun Gate to Hamgyumun Gate(含奎門), the inner wall where the pattern has disappeared is originally composed of geometric and character patterns, and there were also phrases specified as 'Cheonsu(千壽)' and 'Mansemansu(萬世萬壽)'. On the outer wall of the section from Yeonsumun Gate to Hamgyumun Gate, there is a possibility that the phrase known as 'Nakgangmanse(樂彊萬歲)' can be read as 'Cheonsemanse(千歲萬歲)'. In addition, the current outer wall was composed of one drawing board, but in the past, two drawing boards were composed separately.

Sambok (三伏, Three Hottest Days) is the common designation of Chobok (初伏, Early Hot Day), Jungbok (中伏, Middle Hot Day), and Malbok (末伏, Late Hot Day), and widely known to be one of the Korean folk customs. Hence, Sambok is notated in Manseryeok (Ten Thousand-Year Almanac) and in the annual astronomical almanac published by Korea Astronomy and Space Science Institute. In this paper, we investigate the changes of Sambok in Korea based on various documents such as Joseonwangjosilok (朝鮮王朝實錄, Annals of the Joseon Dynasty), Jeungbo-Jakryeoksik (增補作曆式, The Supplement of Manual for Calendar Making), astronomical almanacs, and so forth. According to Jeungbo-Jakryeoksik preserved in Kyujanggak Institute for Korean Studies, Chobok and Jungbok are defined as the third and fourth Gyeongil (庚日, The Day Starting with the Seventh Heavenly Stems in Sexagenary Cycles Assigned to Each Day) after the summer solstice, respectively, and Malbok is the first Gyeongil after Ipchu (Enthronement of Autumn). However, if the summer solstice is Gyeongil, then the third Gyeongil counting from the solstice becomes Chobok. Malbok depends on the time of Ipchu. Ipchu itself becomes Malbok if the time of Ipchu is in the morning, or next Gyeongil becomes Malbok if it is the afternoon. On the other hand, Malbok is defined as Ipchu itself regardless of its time according to Chiljeongbobeob (七政步法, Calculating Method for Sun, Moon, and Five Planets), Chubocheobryeo (推步捷例, Quick Examples for Calendrical Calculations), and so on. To verify the methods used to determine Sambok, we examined the record in the extant almanacs during the period of 1392 to 2100 for which the summer solstice or Ipchu is Gyeongil. As a result, we found a periodicity that if the time of Ipchu is in the morning, in general, the time is in the afternoon after two years and then is back into in the morning after nineteen years, i.e., the 2 + 19 years periodicity. However, we found the 2 + 17 years periodicity in some years. We also found that the Chobok method of Jeungbo-Jakryeoksik has been used since 1712, the thirty-eighth reign of King Sukjong (肅宗). In addition, we supposed that Malbok had been determined by the method like Chubocheobryeo since either 1846, the twelfth reign of King Heonjong (憲宗), or 1867, the fourth reign of King Gojong (高宗). At present, these methods of Sambok are customarily used without any legal basis. We, therefore, think that this study will help conventionalize the method defining Sambok in the future.

Baseball was first introduced in Korea by American Gillette, who was the general manager of the YMCA in the late Joseon Dynasty. There are many discussions about the timing of the first baseball game in Korea, but it has yet to be sorted out. But what is certain is that baseball was introduced directly from the after 1903, when the first Korea YMCA, the Hwang seong Christian Youth Association, was founded. Gillett studied at Springfield YMCA International Training School in the United States from 1900 to 1901. The school is where Gulick worked as a teacher, who actively embraced strong Christianity from Britain and laid the foundation for the YMCA project in the United States. Therefore, Gillett was influenced by this Muscular Christianity, and the reason behind the introduction of baseball in our country is the same Muscular Christianity idea. Gillett, the manager of the YMCA in Korea, has developed various sports projects in Korea based on this Manager idea. It also helped the Korean people, who have been under Japanese colonial rule since 1905, to strengthen their bodies and minds and It helped the independence movement of Koreans. These specific and practical examples are YMCA baseball team active and the 105-member incident.

The material composition of 19 ornaments used for women's hats in the late $19^{th}$ century to $20^{th}$ century, which are kept at National Folk Museum of Korea, was analyzed using SEM-EDS. Sixteen ornaments were composed of $Na_2O$ and PbO, which form adifferent lead glass from those that have been excavated or handed down since ancient times in Korea. The chemical composition analysis has confirmed that two ornaments belong to the mixed alkali glass, while one belongs to the potash glass IIItype. This lead glass is similar in composition to the Japanese craft lead glass that was imported to Joseon during the Japanese colonial era. It is estimated that the lead glass ornaments used in women's hats in the late $19^{th}$ century to $20^{th}$ century were made from raw materials imported from Japan or made from lead glass used for crafts in Japan. This shows that jewelry such as jade and amber, which have been traditionally used in the modern and present ages, have been replaced by craft lead glass imported from Japan.

Korea has the glorious documentary cultural heritage including Annals of the Joseon Dynasty, Memory of the World, from old times. But We had been felt into serious situation, it is very difficult to find some records of late years, through rapid changes of society in modern history. Fortunately, in 1999, "law of archives management in public sector" was enacted but It is some difficult to apply to field. Accordingly, We studied archives laws and record management systems, education systems in Japan and China, neighborhood countries and compared them with Korea's. Life cycle of Gathering, Managing, Using records & archives is reflected in China's archives law, "Dangan" and It is useful to referred to Korea. On the other hand, Japan and Korea's archives law focus on administering and capturing records and archives. In case of Management agency of archives, China has a linear managing system from state to regional agency and Japan and Korea have different system in State and Region. We recommend following items ; reform archives law, status of government archives, professional education and arrangement etc.

Portrait of Sim Huisu is a seventeenth-century Joseon portrait of a meritorious vassal. The National Museum of Korea currently owns two portraits of Sim Huisu, which are the eldest son's family and by the eldest grandson of the family's second eldest son. Both were donated in 1980. Portraits were still in its original mounting, but the supporting silk had been damaged and stained in a flood. Conservation treatment was undertaken to restore the original style, and scientific analysis, such as, X-ray, XRD, XRF and Graff "C" stain, was conducted to study the materials and painting techniques. The support silk was found to be refined fibroin and a plain weave consisting of two weft threads and one warp thread. The lining papers were found to be bamboo fiber paper of first layer in China and Korean traditional mulberry paper in second. Various pigments were identified in the painting, including white lead, cinnabar, atacamite, ink stick, azurite, silver, and gold. The study also confirmed the use of the back painting, with colors such as white ^{White Lead}, green ^Atacamite, orange ^Minium, black ^{Ink Stick}, and yellow ^Dye. Also, it was found that stick ink or dye was used with white lead.

In this study, we tried to reproduce some of the cosmetics from the Joseon period based on the previous analysis of the cosmetics excavated from the tomb of Princess Hwahyup. The two cosmetic powders, the white powder consisting of lead(II) carbonate and talc and the cinnabar-based red powder, were reproduced according to the records from the 6th to the 19th centuries. We also studied the degradation profiles of these reproduced samples by comparison of XRD patterns. Basic lead carbonate of the reproduced white powder turned into lead(II) carbonate, while the reproduced red powder showed different crystalline structure from the excavated cosmetics even after the degradation. Results of the evaluation tests showed that these reproduced cosmetics fell short of the standards set for the modern-day cosmetics, but based on their mixing ratio, the spreadability and oil absorption capacity of some samples of the reproduced white powder were found to be similar to those of the modern cosmetics.
