Modern metal craft is losing our tradition and personality with simple expressive methods and limited techniques without artistry with the purpose of mass production. In order for development of modern metal craft and to succeed our unique culture, there is a need to consider traditional craft techniques that have been delivered since the ancient. Inlay craft requires high concentration and technology, and it is typical traditional metal craft techniques that show contemporary culture and ideas well. the period of the Three States was the time when inlay technique was introduced the first, and it can be seen in Baekje, Gaya and Silla. Furthermore, when inlay craft is applied for modern metal craft, a possibility was found to grant artistic expression and historical value of our unique artistic expression and historical value. For this purpose, it is expected to establish development of modern metal craft and our unique individuality firmly when continuously seeking practical measures that can accept contemporary crafts and expanding opportunities of education to learn traditional techniques.

The Fourth Industrial Revolution has emerged, and technologies of various industries are being converged, compounded, or clouded computing, mobile, or big data. The emergence of a variety of skills and new jobs to match them is bringing the public out of the education and occupation of traditional metal crafts. In this change, craft education should find and study the education method suitable for the present times, and apply it to the educational field to raise public interest and revival. To this end, we will investigate the cases of education in other industries where new materials or technologies have been introduced, and use them in education of traditional metal craft techniques. In addition, we will investigate various cases and features of 3D printing technology and use it for education in craft techniques that have limited time, space and resources.

In modern life, interior decoration has been transformed into a psychological synergistic effect of space, greatly affecting human sensibility. The main point of view in this paper is to study the discovery of new decorative effects and the possibility of products that can replace imported tiles, which account for more than 60% of the walls of indoor spaces closely related to daily life. The solution is to create point tiles using color glass plaster techniques developed in 2018 and to explore the possibility of decorating art walls to meet consumers' purchasing needs using simulations. The four patterns applied to the a paintbrush, resist printing, cutting technique, and inlaid patterns, and the traditional color development effect of the medium color suited to our sensibilities was studied. In addition, through simulation, art walls and acrylic using color glass styles were also used in the kitchen, living room and empty space of the bathroom. Based on this research, ceramic point tiles with a new perspective will be explored and the interior using walls will be activated.

We investigated the effect of PE film thickness on the modified atmosphere packaging (MAP) deastringency of 'Sanggamdungsi' (Diospyros kaki cv.) astringent persimmon at room temperature ($25^{\circ}C$) and low temperature ($-1^{\circ}C$). The fruits were individually packaged with PE film of which the thickness is 60, 80, 100, 115 or $130{\mu}m$ and stored at room or low ($-1^{\circ}C$) temperature. At room temperature, firmness shows the highest value (23.3-26.5) at $100{\mu}m$ thickness. Top flesh browning and decay was monitored at 20 days after storage, and peel blackening and style-end softening was negligible at optimal thickness. Therefore, optimal film thickness of deastringency at room temperature is $80-100{\mu}m$. At this thickness, the astringency was removed after 5 days and the fruits can be distributed until 10 days after the MAP. At low ($-1^{\circ}C$) temperature, firmness was maintained regardless of film thickness. However, the firmness is higher as the film is thicker. Top flesh browning and decay was not occurred even after 90 days after storage. Peel blackening and style-end softening was monitored at 90 days after storage. Off-flavor was monitored at 115 and $130{\mu}m$ thickness. Therefore, optimal film thickness of deastringency at low ($-1^{\circ}C$) temperature is $80-100{\mu}m$. At this thickness, the astringency was removed after 50 days and the fruits can be distributed until 80 days after the MAP.

Jeollabuk-do is bounded by the sea, and Mahan Baekje culture have been established around a wide plain. Also, in southeastern, it was closed by Gaya kingdom where iron culture was prosperous at that time, a variety of the handles of swords with round pommel is excavated at present. The handles of swords with round pommel is the best amount of excavated objects among the swords with round pommel and producted object for the time. It supposes them to become the foundation of making the decorated swords with round pommel. But, the handles of swords with round pommel that don't have a pattern in handle is indifferent to study because the production method is simple in spite of that the value of archaeological data is sufficient. Therefore, in this study, it examined changed production techniques with the change of times concerning the handles of swords with round pommel of Mahan Baekje Gaya period(before 6C) excavated from Jeollabukdo through using X-rays in order to clarify a variety of production techniques of the handles of swords with round pommel correctly in accordance with a period of production and excavated place. As a result, identified production techniques using X-rays of the handles of swords with round pommel excavated around remains of Mahan Baekje Gaya period shows that production progress improved in order of all-in-one shape, hammer welding shape of the handle of round pommel, and two in body formation in accordance with age. Especially, in two in body shape, it products the handle of round pommel separately, after that it welds the handle of swords and then links the sword blade like a riveting or bottleneck and so on. Despite of improved hammer welding technique, the reason why it didn't utilize is it regards as inlay or gilt will be damaged. And it is judged by using riveting or bottleneck. Also, it appears to techniques of metal craft such as decoration of the handle, decoration of point of sword, inlay, and silver-plating in the period of appearing two in body shape. As clarifying correctly, it provides fundamental database of scientific research about a study of production techniques of handle of swords with round pommel.

In Seongju, Gyengsangbuk-do, the Placenta Chamber (胎室, Taesil) of 18 sons and a son of the crown prince of King Sejong(世宗大王) is located in one place. Taesil refers to the place where the umbilical cord and placenta, which are separated when the baby is born, are placed in a jar made of pottery and stone box and then buried on the ground. The placenta chamber in Seongju has the Buncheong ware (粉靑沙器) cover buried on the ground to protect the baby's placenta. These covers are all hemispherical, with a diameter of more the 20cm. The decorations were made using black and white inlaid techniques only on the outside. The Buncheong ware cover with this shape and pattern has been confirmed only in the placenta chamber in Seongju. This study targets 6 of the Buncheong ware cover whose owners were identified, when and where they were prepared, what the stylistic features and meanings are, and where it was produced. The results of the study are as follows. First, ss a result of reviewing the production background and procurement system of this bowl, it was inferred that it was sourced from Jangheunggo (長興庫) at the central government office, between 1436 and 1439, when the event to bury the placenta of royal members in the ground was the most active. Second, it analyzed the unique features of this cover, such as the shape, pattern, and baked traces. The shape and pattern were compared to the ritual objects contained in the Sejong Silok Oryeui (『世宗實錄』 「五禮」, Five Rites of King Sejong Chronicle) and the lid of the royal placenta jar made in the 15th and 16th centuries. Third, this study suggests that the baking method was based on the shape and location of the traces remaining outside the cover. Finally, the following data were used to estimate the production site: the relationship with the 'Jagiso (磁器所, ceramic workshop) registered in the Sejong Silok Jiriji (『世宗實錄』 「地理志」, Geographical Appendix of King Sejong Chronicle); various records of contribution and dedication about the Buncheong ware made here; and the Buncheong ware and related tools excavated from the kiln site in the area. The place where the Buncheong ware cover was produced is estimated to be the most likely production site for the kiln site in Chunghyo-dong Kiln Site, located in Jeolla-do province by synthesizing the data above.

The staff given with chair to Yi Gyeong-seok, senior official over 70 years old by King Hyeonjong of Joseon Dynasty is representative handcraft of Joseon Dynasty. Results of analysis on the metallic decoration show that the metallic ornament of the end part which is connected to the spade was made by rolling of iron plate and brass plating. The plated part is limited to the ornament of the end part connected to the spade and the plating was not applied to the spade. Brass including 20% zinc was used for the connecting part of guard while brass gilded iron was used for the spade. This suggests that the tone of the connecting part of the guard and the spade was not different for reason of visual harmonization. Potential applied plating method can be amalgam, dippping in molten brass, and brushing but the analysis result suggests that dipping in molten brass method is the most likely accepted method. The brass guard of knife was joined by tin-lead solder. Rivet used to fix the blade was made by pure iron as an optimum material which satisfies flexibility and strength.

This study was carried out to find out some similarities and differences of the ornamental technique and motifs in folk furniture between Denmark and Korea which had quite different background of development of folk furniture as one of a cross-cultural study. Furniture made and used in the 18th and 19th century was investigated in order to eliminate the influence of internationalism in the design area in the 20th century. This study was fulfilled by many study trips all over the districts in Denmark to identify Danish folk furniture as well as literature study. Study trips to folk museums. Insa-dong, Janghanpyung furniture market were done for Korean folk furniture. Characteristics of ornament in Danish folk furniture were as followings; Main materials of the Danish folk furniture were conifers, especially pine tree, as pine was very common and easy to get from their surroundings. The most popular and unique types of decoration in Danish folk furniture was painting. Colors used in painted furniture were very bright and vivid. This might be a reaction to the long and dark winter of Scandinavian countries. Motifs used in Danish folk furniture had been chosen to reflect their surroundings. Flowers, six-angular stars, animals, human figures and Biblical motifs were popular sources of decoration for Danish folk furniture. Characteristics of Korean folk furniture were as followings; Main materials of Korean folk furniture were broad-leaved trees as well as conifers, because of their beautiful wood grain. The Korean ways of decoration were different from Danish ones. The method of painting with bright from Danish ones. The method of painting with bright colors was hardly ever used in Korea, except only in lacquering. The most popular decoration method for Korean folk furniture was revealing the natural wood grain with transparent vegetable oil finish, instead of painting. Metal ornament was unique to Korean folk furniture. therefore a lot of metal ornaments were attached on the furniture. Motifs used in Korean folk furniture were more like symbolic than Danish ones. Korean people tried to express their longings and norms through the motifs, such as longevity, prosperity, good luck, and many sons, etc. Therefore, it was natural for Korean motifs to have special symbolic meanings.

Trade specialization index, import market share, unit value index, market comparative advantage index have been applied to compare the competitiveness of forest products in Korean and European markets for the case of Korea-EU FTA. The results say that no items of non-timber products would show a surge of imports as a result of FTA. Timber products, however, such as non-coniferous plywood, continuously shaped wood (non-coniferous), densified wood, wood wool and flour, other (plywood), other (particle board, 441039)), other (fiberboard), oriented strand board (other), other (particle board, 441090), other (particle board, 441031), Prefabricated buildings of wood, fibreboard (of a density exceeding $0.5g/cm^3$ but not exceeding $0.8g/cm^3$), wooden frames (for paintings, photographs, mirrors or similar objects) and wood marquetry and inlaid wood are expected to increase of their imports by eliminating tariffs. For Korean exports no items of non-timber products have competitiveness in European market. For Korean pyroligneous liquid, which is the only competitive timber product in EU market in terms of MCA and TSI, it is difficult to decide whether it has competitiveness, since the actual exports have taken place occasionally during a period of last five years.
