  • We investigated the quality characteristics of fermented ginseng Yakju produced using different percentage contents and application dates of ginseng. Although the pH of fermented ginseng Yakju was not significantly different among the various treatment groups, the total acidity was changed depending on the percentage of ginseng content. the application date of ginseng did not influence the total acid content. The amount of volatile acids was higher at a 0.2~0.3% content of white or red ginseng than in other treatment groups. The ginsenoside contents of white and red ginseng used for making ginseng Yakju were 3,555.0 and 4,447.4 ppm, respectively. In ginseng Yakju, total ginsenoside contents were detected at very small amounts of <10 ppm. A total of 15 volatile components were detected in ginseng Yakju. Higher levels of methanol were produced at early application dates. In sensory evaluations, the preference for aroma was higher at white ginseng levels of 0.5% and 1.0% than for other treatment groups, and the taste was judged to be best at a white ginseng content of 0.3%. In the red ginseng treatment group, a red ginseng content of 0.3% was most preferred for both aroma and taste. The taste preference for white ginseng was at 4 days after application, while the taste of the red ginseng treated group was good at the beginning of fermentation.

  • It is getting higher the demand on a good sound in a car. Like some other sensory qualities, achieving a good sound is still treated as a black-box followed by the individual taste of tuning engineers. This study aims to define the attributes of a good car audio sound and the assessment factors affecting the sound quality. With a variety of surveys on professional listening groups and car audio installers, 26 most frequently used vocabularies are selected as typical presentations of car audio sound quality. After repetitions of listening tests with deliberately selected test CD, pre-recorded 15 different digital car-recordings, headphones replay system, and three different listening groups, it is proved that there are at least 5 different assessment factors which significantly affect the car audio sound quality. They are high fidelity, spectral balance, tonal accuracy, sound stage and acoustic fault.

  • The properties of Puchu(Allium odorum L.)kimchi prepared with different methods were investigated by measuring organoleptic and microbiological properties up to 43 days at 10$\^{C}$ right after preparation. Five conditions of making Puchukimchi included: the addition of salt (treatment A), soybean sauce (treatment B), soybean sauce and perilla seed powder (treatment C), anchovy sauce (treatment D), anchovy sauce and glutinous rice paste(treatment E). Sensory evaluation showed high scores in the appearance, smell, sour taste, good taste, savory taste, texture, and overall acceptability of Puchukimchi prepared with soybean sauce(treatment B). However, treatment C had the best score in good taste. In the intial stage of fermentation, treatment C had higher total microbial counts than others, but in the final stage, treatment E had higher counts than others. Treatment A had less total microbial counts than others throughout the fermentation. The maximum numbers of lactic acid bacteria in other treatments were in the order of treatments A>B>D. In the final stage of fermentation, treatment B had the least number of lactic acid bacteria composed of Pediococcus, Streptococcus, Leuconostoc and Lactobacillus. Streptococcus reached the maximum level at the 8 th day of fermentation, and the number of Lactobacillus was increased with the lapse of fermentation time.
