The purpose of this study is to develop fresh pasta added with superjami, which had a high C3G (cyanidin-3-glucoside). Making fresh pasta with wheat flour and superjami(0, 10, 20, 30, 40%) was done, followed by the mechanical test(moisture content, color value, weight, volume, texture, tension) and the sensory analysis(attribute difference test, preference test). Results are as follows. Moisture content of fresh pasta and cooked pasta was the highest in SP40, and the scores of cooked pasta was much higher than those of fresh pasta. L, a and b value decreased as the ratio of superjami powder. Hardness, chewiness and tension force decreased, while weight, volume, adhesiveness and tension distance increased as the ratio of superjami powder. Attribute difference test showed that color intensity, superjami flavor, savory flavor, superjami taste, savory taste, graininess and after swallow were intense as superjami powder was added. The preference test showed that SP20 containing 20% of superjami powder was the most preferable in flavor, taste, texture and overall quality. Therefore, this was taken as the optimal superjami powder contents for maximizing the overall quality of fresh pasta.

In this study, the traditional takju was manufactured using the finger root, which was recognized as a health functional ingredient, and analyzed the physicochemical and sensory quality characteristics according to the period of fermentation. The pH was significantly low(p<0.05) in all samples until the second day of fermentation, and the pH tended to increase again from the third day of fermentation. The pH value was decreased as the amount of finger root was decreased(p<0.05). The acidity of takju was significantly lower at 0.17~0.21 immediately after fermentation(p<0.05). The acidity of FR0 showed significantly the highest value(p<0.05). The sugar content of takju was significantly increased in all the samples until the 2nd day of fermentation(p<0.05). On the 7th day, it showed the lowest value at $11.01{\sim}12.63^{\circ}Brix$. The sugar content of FR0 was significantly lowest value(p<0.05). The alcohol content of takju was significantly increased as the fermentation proceeded, and the highest value was 11.90~13.50% at 7 days(p<0.05). The alcohol content of RF0 was significantly higher than other samples(p<0.05). As a result of organic acid analysis of finger root takju fermented for 7 days, citric acid(3.35%) showed the highest content of FR3(p<0.05). The content of fructose increased with increasing finger root amount (p<0.05). As a result of sensory evaluation of finger root takju, FR1 and FR2 samples tended to be lower in score than FR0, and FR3 showed the highest score. The overall acceptance value of FR0 was 7.5 and FR3 was 7.57.

This study examines the economic ripple effect on the domestic information security manufacturing and service sectors through input-output analysis. The production inducement coefficient of the manufacturing sector is bigger than the average of whole industry, but that of the service sector is smaller than the average. On the other hand, the service sector is superior to the manufacturing sector in the value added and employment inducement coefficients. Forward and backward linkage effects of manufacturing and service sectors are generally lower than those of the average of whole industry. The information security industry has insignificant contribution to national economy and employment growth overall. In particular, the manufacturing sector records minus contribution to employment growth, which means that a lot of effort for increasing employment must be given further on in the sector.
