Wan is a tableware in which boiled rice or soup, side dish are put, and it is a representative model which shows the development of personal tableware. From the establishing period of Hanseong Baekje, the form of wan which is Jung-do Style(中島式) Plain Pottery of previous period Proto-Three Kingdoms Period was succeeded to, but wan is produced and used as a wan baked in the kiln, which is far development of the producing technique including hardness and clay. By and large, the size of $0.3{\sim}0.4{\ell}$ was the majority and the production technique of wan which used carefully selected soft quality clay are largely confirmed to be two methods which are, first, basic method by which on a clay tablet on the rotating table, clay band is accumulated and moulding is finished, and second, the new method which had the same basic moulding as that of basic method but in the last stage takes wan off the rotating table and reverse it to trim the bottom and remove the angle of flat bottom. The former, basic production method is the classical production method since wan of Jung-do Style Plain Pottery and wan was produced and used for all periods of Hanseong Baekje. On the other hand, the latter is the production method obtained through form imitation of China made porcelain flowed into through interchange between Baekje and China, and through comparison with Chinese chronogram material it is estimated to have been produced and used after middle of 4th century. Therefore it can be known that the Baekje people's demand for China made articles was big and imitation pottery was produced and used with Baekje pottery. In addition, bowl with outward mouth are confirmed in multiple number in Lakrang(樂浪) pottery wan and it is assumed that wan was the form produced under the influence.

A stone mold from the Sabi period of Baekje was excavated at the western tombs in Neungsan-ri, Buyeo where there was a recent excavation survey (2016). It was believed and reported that such stone molds were used for copper needles during the early Iron Age; however, a close re-examination of the form revealed that they were used for bifid ornamental hairpins. Given its casting form, the stone mold of Neungsan-ri is estimated to have been used to make bifid ornamental hairpins in a ∩ shape, narrowing down toward the tip. It is considered an artifact of the Goryeo dynasty. The stone used to make the bifid ornamental hairpin mold of Neungsan-ri was chlorite-schist, the principal minerals of which include chlorite, amphibole, and talc. Similar rocks are in nearby Buyeo (Oesan-myeon), Cheongyang, Gongju, and Yesan. They are mainly found between Jiseon-ri, Oesan-myeon, Buyeo, Sucheol-ri, Yesane-up, and Yesan. Nearly 70 bifid ornamental hairpins from the Goryeo dynasty were excavated at Neungsan-ri, Buyeo and the surrounding areas. Among them, the bronze ones excavated from the tombs of Songguk-ri, Buyeo are estimated to have been made using this mold as they closely resemble the Neungsan-ri mold. Stone was likely the preferred material for molds to make bronze artifacts as it was easy to sink a die. Regarding the bifid ornamental hairpin cast excavated in Neungsan-ri, they obtained stones in nearby areas 20~50km from their location, made bronze artifacts, and distributed them to nearby sites during the Goryeo dynasty. These artifacts suggest that the casting technology of using a stone mold was still employed then.

The Gaya Period is the period in which the nations of Gaya had existed in the Gimhae area. The term 'The Period of the Three Nations', which is widely used, is inappropriate because in ancient Korea, Gaya also existed besides Goguryeo, Baekje and Silla. This term should be corrected for the accurate reconstruction of the history of ancient Korea. Of course, the term 'The Gaya Period' cannot replace 'The Period of the Three Nations'. It just means the period in which the nations of Gaya existed. The Gaya Period refers to the period of about 600 years from about the first century, in which several nations of Gaya began to appear in the Gyeongsangnamdo area, through the falls of Daegarak of Kimhae in 532 A.D. and Daegaya of Goryeong in 562. When doing this, there should be no distortion of the original form of the relics. With the application of traditional techniques and excellent relics, it is believed that it helps to create the high added values by putting culture and tourism together with the development of various designs of cultural goods. To suggest possibility of jewelry designs by completing protype from idea scatch.

We applied the seismic method to investigate the site characteristics around the Circular Pond (top diameter 7.3 m, bottom diameter 3 m, and depth 4.78 m) at the Ssangsujung Park within the Gongsansung in Gongju. Previous excavations for the cultural assets beneath the Ssangsujung Park disclosed the assumed site of the Palace of the Beakje Dynasty and the Circular Pond containing the Bakje relics. We demonstrated that the seismic prospecting can be applicable to delineate the underground structure around the cultural properties by the three kinds of seismic approaches: walk-away test, conventional refraction method, and equal-distance refraction survey. The last method which is designed by this work ran detect the I-W variations of seismic velocity in the subsurface medium across the Circular Pond on the basis of the difference of the P-wave arrival times between the 1-m-spacing 24 geophones and the corresponding 24 shots parallel with the geophone profile. From the combined results, prominent three-layer velocity structure is observed around the Circular Pond. The bottom layer is interpreted as the basement rock which is exposed near the Ssangsujung whereas the upper layer with relatively lower velocities is interpreted to be the artificial covering. The basement depth beneath the Circular Pond is deeper than the norhern area. The western basement of Circular Pond has the thicker weaker layer compared with the eastern part. Thus, the middle layer could be constructed as the artificial foundation during the Beakje Dynasty. Consequently, the Kong-sansung Circular Pond is possibly built upwardly rather than digging.

In Bongseon-ri site, the central type and the local type of the Baekje tombs co-exist together. Many swords with ring pommel which to regional leaders in Seocheon the Beekje government granted are excavated from these tombs. These represent that the regional leaders were controlled by the Baekje government gradually. Four swords with ring pommel and one simple sword are investigated metallurgically and we seek what swords have a function of weapon or what sword produce for grave goods. The simple sword is made by solid carburizing technology and quenching of heat treatment so it's possibly used as a weapon. In contrast, four swords with ring pommel has little chance of weapon because the blade of swords consists of microstructure that have low hardness and the back of swords don't have microstructure can absorb the shock. The most identical characteristic of the simple sword and swords with ring pommel is that they are possible to classify clearly into practical/non-practical tools. Additionally, according to non-metallic inclusion analysis result of these swords, w$\ddot{u}$stite and glass phase are found together. Thus, it is able to say that reduction method in low temperature is applied during smelting process.

This article examined the burial type, wooden coffin and its historical significance of Iksan Ssangneung, the royal tombs of Baekje. Ssangneung was found to be the royal tombs of King Mu(武王) and queen through the burial type, wooden coffin, articles such as chinese jade ornaments and the deep relationship between King Mu and Iksan region. The reason of constructing Baekje royal tombs in Iksan region can be examined at many aspects. First, Iksan was a very important place for King Mu. Because Iksan was the basis of his political growth. Also, Iksan was a important geopolitical location in relation with Silla(新羅). For this reason, Iksan was developed in earnest. The construction of major facilities such as royal palace and temples in Iksan suggest the transfer of the capital from Sabi(泗?) or the preparation and partial execution at least. However, the transfer of the capital was not completed. It can be seen as the incomplete city. However, even after King Mu Iksan was maintained as the important region by King Euja(義慈王). It can be seen through the maintenance of great temples such as Jeseoksa(帝釋寺) and Mireuksa(彌勒寺) built at later period of King Mu and royal palace area, even though royal palace had turned into the temple. These inherited consciousness may have been embodied in the act of building royal tombs of King Mu and queen.

Centering around ruins recognized of being relatively early stage related to flat tile and brick, excavated in Silla capital area, the study attempted elementary approach to seek the appearance time of every remain through comparing them from the excavated cases and production methods of Short beating, Medium beating plate, Long beating plate and Stamped-roof tile. Gyeongju began to use the short beating plate made of tile-less plates or tile plate and increased its quantity. That is deemed to be due to efficiency of beating plate making methods, and moreover to be limited only for use in the palace castle and offices. That is, making short beating plates is presumed to be made merely under some definite objectives. Medium beating plate has been spread to the whole country since Silla and Baekje united. Differently from Koguryo and Baekje, Silla had its unique Beating-plates making technology available for mass-production, which was spread to the whole country and resulted in disappearing of Koguryo and Baekje technology. Long beating plate was not nearly founded in Gyeongju area, but flat tile and common tile excavated in Sachunwang Temple site and Samrang Temple 3rd remains are known. In the outskirts of Gyeongju, long beating plate appeared between the latter half of 8C and the beginning of 9C. Until now, different views have raised to appearance of long beating plate of Unified Silla, which is expected to be clarified under the situation excavated by position relations. Stamped-roof title in Gyeongju is estimated as used after the datum point year 679. While in Baekje area, five stems and branches were involved, in Silla area, code or sign was shown much. The difference between two areas would be due to each other factory, and especially the marked contents werenot letters, which means it had been changed from Baekje s existing-methods. That is, it says the production environment changed owing to Silla's merging. And stamped-roof tile was temporarily used in Gyeongju but soon disappeared, which was because Silla beating plates made under cylinder-shaped tile barrel(圓筒瓦桶) and hitting-pressing of Medium beating plate had beenspread to the whole country, so the production technology of Koguryo and Baekje was naturally dismissed. In consequence, the mergence by Silla brought about unification of each nation's special technology.
