A new type of Bi based glass frit was developed for Ag paste in PDP applications and its properties are compared with the commercially used Pb based glass frit. After optimization of the properties of Bi based frits for PDP application such as the softening temperature and the coefficient of thermal expansion (C.T.E), the screen printed electrodes prepared with the Bi based fit contained Ag paste were characterized. In $Bi_2O_3-B_2O_3-Al_2O_3$ glass system with the more than 50% of $Bi_2O_3$, the softening temperature, the thermal expansion coefficient and the line resistivity was 400∼$480^{\circ}C$, 7.31∼$10.02\times 10^{-6}/^{\circ}C$> and 4.1∼4.8$\Omega$ respectively. Properties of the Bi based frits are comparable with the Pb based frits. A printability and an uniformity of the Bi based frits were excellent in screen printed Ag eletrode. The Bi based frit system is an excellent candidate material for Pb free and Alkali free frit in PDP applications.

We investigated the functional characteristics of commercial wood charcoal in Korea and their application as functional raw materials. The areas of analysis were anatomical features, elementary composition, mineral composition, caloric values, anion and far-infrared ray emission, and moisture absorption capacity. Based on the analyses as above mentioned, it is considered that charcoal can be evaluated as functional raw material. In commercial wood charcoal in Korea, there were highly varied depending on manufacturing methods as black charcoal, white charcoal and mechanical charcoal and manufactures for elementary composition, mineral composition, anion emission, far infrared ray emission. Especially, black charcoal showed lower moisture absorption capacity than white charcoal and mechanical charcoal. For charcoal as functional raw material, selective usage are needed based on the analyses of anatomical features, elementary composition, mineral composition, caloric values, anion and far-infrared ray emission, and moisture absorption capacity. Specific charcoal making methods for improving specific functionality, required as functional raw material, are necessary in further research.

과실류의 단맛 결정인자인 유리당의 함량을 계통별로 분석하여 생식 및 가공 식품의 원료로서 오디의 이용성을 높이고 오디의 과실화 촉진을 위한 기초자료를 제공함은 물론 오디 생산용 뽕나무 육종효율을 높이기 위하여 유전자원으로 보존 중인 뽕나무 계통에 대하여 결실 오디를 채취하여 유리당의 조성과 함량을 비교ㆍ분석하였다. 동시에 유리당의 함량이 높은 계통을 선발하여 수량, 과중, 당도 등 과실적 특성을 고려하여 오디생산용 계통으로서의 가능성을 검토하였다. (중략)
