This study interpreted the chemicals of the pigments and the coloring techniques employed on Youngsan Ritual Ceremony Buddhist Painting through a nondestructive analysis method and a microscopic observation. Based on the interpretation, this study closely examined the chemical properties of the names of the coloring materials specified on the ceremonial writing of the Buddhist painting. It is estimated that lead white was used for the white pigments, orpiment and organic pigment for the yellow pigment, cinnabar/vermilion, minium, red ochre, and red dyes for the red pigments, malachite or atacamite for the green pigments, azurite and indigo for the blue pigments, and ink stick for the black pigments. The pigment names specified on the ceremonial writing are juhong, jungcheong, hayeop, whangdan, and whanggeum, and it was verified that juhong is cinnabar or vermilion, jungcheong is azurite, hayeop is malachite or atacamite, whangdan is minium, and whanggeum is a gold foil.

Morphological characteristics and life cycle of Udea ferrugalis (Hubner) attacking Angelica utilis were studied in 1995 and 1996. Egg of U. ferrugalis was oval-shaped with light-gray. Larva was milk white or light yellow color with 1.50-14.6 mm body length, depending on their developmental stages from 1st to 5th instar. Pupa were deep-brown with 8.2-9.7 mm length. Adults were brown color and body lengths were 10.1 mm and 8.3 mm and wing expanse lengths were 18.5 mm and 16.6mm with female and male, respectively. At 20$^{\circ}$C, each developmently periods was 5.81, 19.0, 3.46 and 1 l.0days with egg, larvae, pre-pupae, and pupae, respectively. Also adult longevitys were 10.13 for female and 9.8 days for male. Average number of egg were 238.5 and 248.8 at 20$^{\circ}$C and 30$^{\circ}$C, respectively. A total of 12 species host plants were identified in the outdoor observation in Chungbuk province.

The aim of this study is to investigate the traditional manufacturing technique of lacquering by comparing and analyzing materials used for wooden lacquerware artifacts with focus on the Joseon dynasty Eugye, and to apply the manufacturing technique to the conservation treatment of the lacquerware. artifacts. This study conducted the documentary survey focusing on "Yongjo Jeongsun Queen Consort Garye Dogam Eugye",and "Jeongjo Gukjang Dogam Eugye." The royal lacquering is roughly classified into three categories-scarlet lacquering, quality black lacquering, and terra rosa lacquering- according to materials used for lacquerware. The bean flour was mostly used for under lacquering of the articles which was offered to the king and in case of other articles, bean flour was used mixed with bone ashes. In some cases, burned pine soot was added to under lacquering. Japanese scarlet lacquering was applied by mixing maechil-main coat, in inverted commas- with Japenese scarlet after lacquering jeonchil-base coat, in inverted commas-. In case of Chinese scarlet lacquering, part of terra rosa was used mixed with red clay. For quality black lacquering, basically jeonchil and maechil were used, but sometimes part of burned pine soot was added. In addition, terra rosa lacquering was applied by basically using terra rosa mixed with red clay. Lastly, gloss was given by using perilla oil. It is expected that the traditional materials and technique examined through both documentary and relic research will contribute to advanced result of the conservation treatment of wooden lacqueringware artifacts.

현대사회의 소비자는 극도의 편리성을 추구하는 경향이 있다. 식품업계에서는 이를 충족시키기 위하여 다양한 형태의 인스턴트 식품을 개발하고 있으며, 이에 따라 식품의 포장용기도 매우 다양해지고, 일회용 식품포장용기의 사용도 급증하고 있다. 일회용 식품포장용기는 그 재질에 따라서 유해물질이 용출되거나 갖가지 형태로 소비자의 건강을 위협하고 있다.(중략)
