This study was conducted to evaluate the physicochemical characteristics, perform a sensory evaluation of glutinous barley gruel after adding Hizikia fusiformis powder to promote consumption, and identify the best ratio and recipe. The gruel was prepared with rice and glutinous barley powder, and various levels (0, 2.5, 5.0, and 7.5%) of H. fusiformis powder. pH, color, viscosity, and spreadability of the gruel were investigated. A sensory evaluation was conducted by 20 panelists in the categories of color, flavor, taste, texture appearance, and overall preference using a 9-point hedonic scale. The viscosity and pH of the gruel increased as H. fusiformis powder content increased, whereas spreadability of the gruel decreased gradually as H. fusiformis powder content increased. As the level of H. fusiformis powder increased, lightness decreased significantly, whereas redness and yellowness increased. Color, bitter taste, and H. fusiformis flavor of the gruel increased significantly as H. fusiformis powder content increased. On the other hand, sweet taste (delicious taste level) and viscosity were not different among the different gruels. The sensory test results indicated that the gruel with 5% H. fusiformis powder had the best overall acceptability. In conclusion, glutinous barley gruel with 5% added H. fusiformis powder was more acceptable than the others.

-This study used general carbon fibers(CF), which can be utilized for a low voltage cable screen, as well as metal-coated carbon fibers(MCF) to make cables and analyzed the properties of electromagnetic effectiveness. Both braid CF and MCF cables with 3,000 strands, 16 spindles, and braid density of 90% or over were adopted. The tape-type MCF specimens were spread into a tape(width: 15mm) using a hot melt to make a cable. The shield effectiveness was measured up to the 1GHz range in accordance with IEC 62153-4-6; braid shielded cables featured a superior shielding effect at 63dB than tape-type shielded cables. That was because the tape-type shielded cable has relatively more gaps and holes between carbon fibers than the braid type, resulting in a more inflow or emission of electromagnetic waves. In the case of braid cables, the characteristics of their electromagnetic waves were enhanced, with higher spindles and higher conductivity of carbon fibers. The shield effectiveness of the MCF shielded cable, however, was lower than that of tin-coated one.
