The breadmaking characteristics of composite flour containing 10-50% of buckwheat and wheat, were studied to establish the optimum formula for the development of buckwheat bread. As the proportion of buckwheat flour increased in bread formula, the water absorption and loaf volume decreased, but the loaf weight increased. Buckwheat flour was added to wheat flour at a replacement level of 30% without a large adverse effect on bread quality. As the amount of buckwheat flour increased, crust and crumb color were getting dark. According to the sensory acceptance test, buckwheat bread containing higher bran content were preferred to those with less brain. The sensory quality determined by QDA(Quantitative descriptive analysis) showed as follows: The size of air cells, buckwheat flavor, mustiness, bitter taste, aftertaste, firmness, grittiness, and crumbliness increased, but moistness and springiness decreased in buckwheat breads containing 10-30% replacement levels of buckwheat for wheat flours. The overall quality decreased as the amount of buckwheat flour increased.

Hydrogenated amorphous carbon(a-C:H) films were prepared by PECVD(Plasma enhanced-chemical vapor deposition) method. The films were characterized using various spectroscopic measurements such as Raman scattering, FTIR(Fourier transform infrared) absorption spectroscopy. FRIR absorption reflects only the optically active hydrogen in the a-C:H and, using it together with Raman spectroscopy. The spectral analysis indicated that changes in Raman spectroscopy intensity occurring with increasing substrate temperature 50℃~300℃ were determined to be caused by changes in optically resonant components in the films. Furthermore, a significant correlation was the two crystalline forms of carbon-graphite and -diamond consist of sp² and sp³ bonds, respectively. Significant changes in chemical bonding(sp²/sp³) and micro-structure of hydrogenated amorphous carbon thin films occur as the substrate temperature varies from 50 to 300℃ during.

The purpose of this study was to evaluate the effect of adhesive curing timing on the direction of polymerization shrinkage of light-curing composite resin. In this study, the curing times of adhesive and composite resin were measured by differential scanning calorimeter(DSC). 28 extracted human molars were embedded in clear resin and box-type cavities were prepared. Based on DSC data. the experimental teeth were divided into 4 groups. Group 1: no bond: Group 2: late curing: Group 3: Intermediate curing: Group 4: Early curing. After treating with adhesive, the buccal cavities were filled with Z-100 hybrid composite resin and the lingual ones were filled with AEliteflo flowable composite resin. The depressions at the surface were measured by surface profilometer, then the specimens were embedded in clear resin and sectioned. Impressions were obtained and used to get epoxy resin replicas. The epoxy replicas were gold-coated and observed under SEM. Average Maximum Gap(AMG), Gap Proportion(GP), Average Marginal Index(AMI) were used to compare the shrinkage gap of each group. The results were statistically analyzed using the Kruskal-Wallis One Way ANOVA, Student-Newman-Keuls method. The results of this study were as follows. 1. Average Maximum Gap. Gap Proportion, Average Marginal Index and depression at the surface of Z-100 hybride composite resin were smailer than those of AEliteflo flowable composite resin(P(0.05) 2. When the bonding between composite resin and tooth structure was strong, the shrinkage gap was small, and depression at the surface was deep(P<0.05). 3. In the well-bonded group. light-curing composite resin shrank toward bonded cavity wall. not toward light source. The result suggested that the direction of polumerization shrinkage was affected by the quality of bonding in the dentin-resin interface. The strong was the bonding between composite resin and tooth structure, the smaller was the gap and the deeper was the depression at the surface. Then the flow to compensate the polymerization shrinkage proceeded from surface to bonded cavity wall.
