This paper examines the material culture of the Goryeo-Joseon Period through changes in the design and crafting of the earpick. In Chapter 2, terminology regarding earpicks is presented, and the culture of using earpicks is examined through fragmentary literature of the late Joseon Dynasty. Earpicks were first a personal hygiene tool, and, secondly, they played a symbolic role as a style accessory used by men, analogous to the fan carried by women of the time. In Chapter 3, earpick form are classified by period, and characteristic decorative techniques for each form are examined. During the Goryeo Dynasty, earpicks were sanitary tools, and, according to their form, they were classified into single and complex types. From Unified Silla to Goryeo, there is an angled type of connecting rod, and in the Goryeo period, there appeared earpicks with colorful decorations on the handle, completely forged earpicks with a thin and long shape, and earpicks which were part of multitools. Common decorative techniques include line expression, gold plating, cheophomun on the background, and inlay. Earpicks of the Joseon Dynasty are classified into sanitary tools or ornaments, according to their purpose of use. Sanitary tools are divided into single type and complex type, and earpicks used as ornaments include headdress, norigae, and sunchu. For earpick accessories, headdresses and norigae were used for women, and sunchu was used for men. The decorative techniques of earpicks during the Joseon Dynasty were mainly seen in the headdress earpicks. They were decorated with various colors in the Cloisonné method or bejeweled. Research on everyday tools among crafts is lacking; greater attempts to read the flow of time and approaches to material culture through everyday tools should be made.

The 21st century is as an age of culture, and cultural goods presenting the cultural spirit of one nation should reflect the tradition, culture, and techniques of that nation. The twelve horary signs of the gods are the creatures of our nation's native religion and thought have existed from the unified Silla period to today. Therefore, many things belong to the category of cultural goods, but in this study the guidelines for the design of cultural goods are limited to the characters of the twelve horary signs. For this study concept and classification of cultural goods, Korean traditional formative special qualities, concepts and composite elements, symbolic meanings and special qualities, personifications, and unique images of twelve horary signs of are researched. According to the results of the research guidelines for the design of cultural goods, images of cultural goods, classifications applying to each subject, the formative special qualities of Korean traditions, personifications, and concepts on the development of cultural goods are presented..

A stoneware bottle was recovered from the Incheon Yeongheungdo Shipwreck in 2013. Primary observations showed that this object had a sealed opening and was covered with a foreign material. After it was cleaned via mechanical and chemical methods, wave patterns were observed on the outer surface of the bottle and a yellowish-brown transparent material was found within. In this paper, the process of conserving the stoneware bottle and the analysis conducted on the unknown material found within is explained. The conservation process included steps such as cleaning, desalination and restoration. After of the missing area located at the rim, the original shape of the bottle was made clear. In addition, the unknown inner material was analyzed using FT-IR and GC-MS. Results showed that the material is similar to golden lacquer. It is speculated that the Yeongheungdo Ship had wrecked during the Unified Silla period while carrying a bottle loaded with golden lacquer.

Egg is a food that has been loved from ancient times by people all around the world. It has been called a present from god because its rounded shape was believed to refer to the earth. We found the oldest and most perfectly preserved egg fossil at Chunmachong (天馬) in Kyungju (慶州). We believe that it was used during the period of the Three States or the unified Silla (新羅), and, accordingly, it was a noble food that has been found at the king's grave of the age. Egg, which is called egg of chicken in Korean, was written as egg of chicken (鷄卵), son of chicken (鷄子), bird's egg of chicken (鷄蛋), and round thing of chicken (鷄丸) in the Korean alphabet and Chinese characters. The ancient countries had the following myths about eggs In myths about offspring by egg, they were born as heaven's will to make them god. There were 19 proverbs: 'Hitting a rock with an egg', 'It's like the yellow part of an egg' and 'Even an egg stops when it rolls', etc. According to a theory of divination based on topography, people use eggs when they find a good place. There are 10 proverbs (四字 成語): Dongjiipran (冬至立卵), Nanyeoseoktu (卵與石投) etc. Studies for analysis of egg recipes found in the old literature (cooking, agriculture and fishing, and medical books) in the Chosun Dynasty recorded 36 times where cuisine with egg was mentioned as the main ingredient, 154 times as a sub-ingredient, 79 times as a garnish, and 20 times etc. As a garnish, they were 'finely sliced', 'thin rectangular and the rhombus form', and 'rounded shape'; after grilling they were divided into yellow and white parts. When cooked, they were used in comparison of the size or shape of an object with that of other objects.

This paper is an architectural historical study on Chimi of Hwangnyongsa Temple. In this research, the shape and cross-section of the chimi are reviewed. The results of the study are as follows. The chimi is a form in which the head part facing the maru is omitted, and the upper and lower body are separated. The upper and lower bonds are assembled into a two types of joint throughout the side of the torso, and then bound with an iron strap. Because of the absence of ridge line in the front, and the narrow curved surface which makes the side plate close to the plane, the entire cross-section is triangular, and the rear plate maintains the shape of the chimi. The naerimmaru connected to the side of the chimi has a slope, so it is clear that the chimi was used on the woojingak-jibung(hipped-roof), and the wing part and back of the chimi are erected on the side roof. The height of the yongmaru and chunyeomaru is about the same and the roofing tiles of those are in contact. The roofing tiles of chunyemaru should be cut to fit the angle of the contacting part. The maru is 30 stories high of roofing tiles as a result of the on-board survey. Based on reference on the shape and timing of the production of chimi, the height of chimi, and the maru is believed to have been built before the Unified Silla Period and used in buildings with at least seven-kan frontage. Buildings corresponding to these construction conditions can be seen as Central hall and East hall in Hwangnyongsa temple.

This study investigated seven specimens of lead-glazed paving bricks in order to identify the materialistic characteristics of the lead glaze used for paving bricks during the late Unified Silla period in Korea. The samples were excavated from the Beopgwangsa Temple site, Pohang. As a result of observing the surface and cross-section of the glaze with a microscope, the study confirmed that the lead glaze demonstrates various traits of hydration, which were classified into four layers: Surface layer, hydration layer A, hydration layer B, and green layer. After measuring the composition of each layer with SEM-EDS analysis, the green layer was found to have been less affected by the external environment, which renders it highly reasonable to view the green layer as the original composition of the lead glaze. The green layer is a low-temperature glaze composed mainly of PbO and SiO₂ at a ratio of 8:2, with approximately 2% CuO acting as the main colorant. Comparing the green layer composition with those from Gyeongsang-do, it was confirmed that the mixture ratio of lead glaze materials was similar to other sites such as the Sacheonwangsa Temple site, the Cheonryongsa Temple site, and the Buseoksa Temple site.

Great Dharani Sutra of Undefiled Pure Light (Gwi) (LKH 10703) donated by the family of the late Lee Kun-Hee to the National Museum of Korea in 2021 is a calligraphy album consisting of sixty-two leaves compiled using butterfly binding. It contains Great Dharani Sutra of Undefiled Pure Light, "Record of the Production of Mugujeong Pagoda by the Order of King Munseong," a postscript by Kim Jeonghui, and an appreciation record by Oh Sechang. This paper has revealed that this album is identical to the material that Suematsu Yasukazu introduced in Volume 15 of the journal Cheonggu hakchong in 1934 and that it includes elaborate copies of Great Dharani Sutra of Undefiled Pure Light and "Record of the Production of Mugujeong Pagoda by the Order of King Munseong" on yellow Chinese paper, both of which were excavated from inside the Mugujeong Pagoda at Changnimsa Temple in Gyeongju in 1824. It has also reconfirmed that it is highly probable that the Great Dharani Sutra of Undefiled Pure Light that Jo Byeongsun, the former director of the Seongam Old Books Museum, unveiled in 1998, is a transcription of the original sutra excavated from Mugujeong Pagoda at Changnimsa Temple in Gyeongju. Moreover, it has concluded that the Great Dharani Sutra of Undefiled Pure Light owned by Park Cheolsang is likely to be another example of copying the transcription of the original sutra excavated from the Mugujeong Pagoda at Changnimsa Temple in Gyeongju. In the album of copies donated by the estate of Lee KunHee, six of the Chinese characters promulgated by Empress Wu were used fifteen times in total. Four of the characters of Empress Wu were utilized ten times in the Great Dharani Sutra of Undefiled Pure Light (national treasure, Bulguksa Temple collection) found among the reliquaries from the Three-story Stone Pagoda at Bulguksa Temple in Gyeongju and were also seen in the album of copies donated by the estate of Lee Kun-Hee. The use of the same characters of Empress Wu and other variant characters suggests that both the album of copies donated by the estate of Lee Kun-Hee and the Bulguksa sutra were based on an edition distributed in the Unified Silla Period during the eighth century. Kim Jeonghui confirmed the exchange of calligraphy between Korea and China through studies on bronze and stone epigraphs. He believed that the Great Dharani Sutra of Undefiled Pure Light and "Record of the Production of Mugujeong Pagoda by the Order of King Munseong" excavated from Mugujeong Pagoda at Changnimsa Temple were authentic materials showing the elegant calligraphic styles that prevailed before the Ouyang Xun style. Thus, the album of copies donated by the estate of Lee Kun-Hee holds great historical and artistic significance in that it is a rare example of Kim Jeonghui's evidential study of a transcribed sutra and an original record of the production of a pagoda from the Unified Silla period.

Efforts had been made to eliminate the brittleness unique to cast ironware from 5 BC up until the time that cast ironware became widely used. One of the techniques used to this end was to produce the cast ironware in one kiln and then anneal it in another kiln. This technique condensed or removed the carbon in the structure to eliminate the brittleness of cast ironware and enable forging. To clarify the nature of this technique, this study examined cast ironware made of malleable cast iron, which manifests the characteristics of the annealing technique for cast ironware excavated on the Korean peninsula, based on current steelmaking technology and research results from China and Japan. Results confirmed that all cast ironware made of malleable cast iron had been imported into Korea until the Proto-Three Kingdoms Period. Also, since the Chiljido (Seven-Branched Sword), which is housed at the Ishigami Shrine in Japan, appears to have been produced in the Korean peninsula, it is determined that Baekje in the 4^th century must have possessed such an annealing technique. At that time, however, iron was produced mainly with an iron bloom, and a large amount of forged iron was produced with a steel bloom smelted from an iron bloom. In addition, most of the cast ironware that was used previously, except for cast iron hoes, had been replaced by forged ironware. In other words, this annealing technique was not used frequently until the Three Kingdoms Period. However, it spread broadly during the Unified Silla Period in so much as it was identified in the Jangan-ri remains, which represented the regional hub of iron production and distribution.

This research explored the relationship between the water quality issue of Wolji Pond (Anapji Pond) with the maintenance of the channel flow circulation system. The water supply and drainage system closely related to the circulation system of pond has been reviewed, rather than the existing water supply and drainage system that has been analyzed in previous studies. As a result of reviewing the water supply system, it has been learned that the water supply system on the southeastern shore of Wolji Pond, being the current water supply hole, has been connected to the east side garden facility (landscaping stone, curved waterway, storage facility of water) between the north and south fence and the waterway. This separate facility group seems to have been a subject of the investigation of the eastern side of Wolji Pond, with the landscaping stones having been identified in the 1920's survey drawings. The water supply facility on the southeastern shore, being the suspected water supply hole, seems to have some connection with the granite waterway remaining on the building site of Imhaejeon (臨海殿) on the southern side of Wolji Pond. It is inferred that it provides clean water, seeing that the slope towards the southwestern shore of Wolji Pond becomes lower, the landscaping stones have been placed in the filter area, and it is present in the 1920's survey drawings and the water supply hole survey drawing of 1975. The water drainage facility on the northern shore is composed of five stages. The functions of the wooden waterway and the rectangular stone water catchment facility seem not to be only for the water drainage of Wolji Pond. In light of the points that there are wood plugs in the wooden waterway and that there is a water catchment facility in the final stage, it is judged that the water of Balcheon Stream (撥川) may be charged in reverse according to this setup. Namely, the water could enter and exit in either direction in the water drainage facility on the northern shore It also seems that the supply to the wooden waterway could be opened and shut through the water catchment facility of rectangular stone group as well. The water drainage facility on the western shore is very similar to the water drainage facility on the northern shore, so it is difficult to avoid the belief that it existed during the Silla Dynasty, or it has been produced by imitating the water drainage facility on the northern shore at some future point in time. It seems to have functioned as the water drainage facility for the supply of agricultural water during the Joseon Dynasty. The water supply and drainage facilities in Wolji Pond have been understood as a systematized distribution network that has been intertwined organically with the facility of Donggung Palace, which was the center of the Silla capital. Water has been supplied to each facility group, including Wolji Pond, through this structure; it includes the drainage system connecting to the Namcheon River (南川) through the Balcheon Stream, which was an important canal of the capital center.

The Conservation Science Team of National Museum of Korea has established the data base of lead isotope ratio as the scientific research of bronze patina, which was acquired from conservation process of metal objects, and based on this result, it intends to conduct the research related to the production places of raw material for the bronze objects. As the equipment for analysis of lead isotope ratio of the bronze patina, the thermal ionization mass spectrometer (TIMS) was used. As part of the research, in 2007, the 11 samples of the bronze Patina from the objects, believed to belong to of Nangnang(Lelang), the 6 items of bronze patina from the flower-shaped bronze dishes, belong to Unified Silla period and 4 items from the Goryeo bronze bell were acquired and analyzed the lead isotope ratio. Based on the data of the lead isotope ratio from the galena of Korea, China and Japan, the provenance raw materials were estimated through the comparison of their lead isotope ratios. In the future, the Conservation Science Team of the National Museum of Korea will collect as much bronze patina as possible from the process of conservation treatment of metal objects, and analyze them in order to conduct the study of provenance with the type, period and the region of the objects.
