  • This study investigated the antioxidant activity and general and sensory properties of soybean curd supplemented with Codium fragile. The yield of soybean curd containing 0%, 20%, and 40% C. fragile was 113.62, 104.09, and 108.06, respectively. Antioxidant activities and pH were significantly increased (P<0.05) depending on the amount of C. fragile supplemented in soybean curd. Compared to that in additive-free soybean curd (control), the amount of crude ash and protein in soybean curd containing 40% C. fragile was significantly decreased (P<0.05) and increased (P<0.05), respectively. We observed a dose-dependent increase (P<0.05) in the hardness and chewiness of soybean curd concomitant with the amount of C. fragile supplemented. In contrast, we observed no significant difference (P>0.05) in soybean curd's cohesiveness between the groups. As determined by sensory evaluation based on seven-point hedonic scale, soybean curd supplemented with 20% C. fragile received an excellent score (6.55) for color. As the same method, we observed that the flavor and overall acceptability significantly increased (P<0.05) in the C. fragile content increased. Taken together, the antioxidant and sensory assays in our study make a compelling case for the practical development of soybean curd supplemented with C. fragile owing to its good antioxidant activities, general properties, and consumer acceptance.

  • Among various kinds of hearing aids which have been developed so far. the conventional air conduction hearing aids have some problems such as the acoustic distortion, an howling effect due to acoustic feedback. Another type of hearing aid. the cochlear implant system can be applied to the profound imparied person. However. it shows the disadvantage that there is no possibility of recovery of the acoustic organ such as ossicle. On the other hand. the implantable middle ear heaving device directly vibratos the ossicular chain and has better sound qualify. good cosmetics for appearance. and wide frequency responses so that it can overcome the defects or the conventional hearing aids. In this paper, a mathematical modeling and a momentum equation derivation of the DET has been performed. For the optimization of the structure dimension generating maximal vibrating force of the DET. the computer simulation using a finite element analysis (FEA) software has been performed. Also. the vibrating transducer has been designed to make the frequency characteristics or the transducer be similar to those of the normal middle ear. Through the experimental results, the measured vibration characteristics of the DET has been evaluated to verify the performance for the application to implantable middle ear hearing devices.

  • In this study, we evaluated the performance of a companding strategy as a preprocessing for speech enhancement and noise reduction. The proposed algorithm is based on two tone suppression that is human's hearing characteristics. This algorithm enhances spectral peak of speech signal and reduces background noise, however it has tradeoff characteristics between speech distortion and noise reduction due to limited channel number and nonlinear block. Therefore, we designed two different companding structures that have relative characteristics of noise reduction and speech distortion and found suitable companding structures by difference of individual speech perception ability in noise environment. Thus we proposed speech perception enhancement of cochlear implant user in noise environment with low SNR. The performance of the proposed algorithm was evaluated through 5 normal hearing listeners using noise band simulation. Improvement of speech perception was observed for all subjects and each subject preferred the different type of companding structure.

  • The performances of speech compression schemes appeared to be dependent on the response profiles to compressed stimuli and the features of individual languages to some extent. Although these response profiles were critical in comparing various compression outcomes, the related data were limited in number for Korean monosyllabic words. From the previous study, data from PNT (Preserving No Trait) compression was selected as a base set for comparison. In this study, the outcomes from PPT (Preserving Pitch Trait) and PTT (Preserving Time Trait) were analyzed under the same condition. Then, the properties of these three widely used representative compression schemes were quantitatively compared in normal hearing adults (N=20) for controlled Korean quintet digit sets (0 through 9). Results showed that PPT compression scheme exhibited the best perceptual performances for the Korean quintet digit sets in the final outcomes (PPT>PTT>PNT). The compression ratios of 50% performances were estimated as about 20%, 42%, and 44% for PPT, PTT, and PNT, respectively. The data indicated the influences of the salient psychoacoustic features of the three representative compressions on perceiving Korean monosyllabic digit words. This controlled procedure with monosyllabic quintet sets can evaluate efficiency and effectiveness of other compression schemes and may also contribute to diagnosing auditory processing disorders and fitting special hearing aids with compression issues.

  • Although Rotoscoping technique has been used for a long time to mimic the natural and smooth motion since the early 20th century, its artistic value was devalued as tricks because it traces the already recorded images. But the fact that the rotoscoping images can cross the boundaries between animation and live action in an infinite integral freedom in the digital era became rather expansive new aesthetic possibilities of representation of the reality. In addition, Jonas Odell's animations such as (2010), (2008), (2006) are good example to prove that the rotoscoping images also can serve as means to enhance its narrative. This study is to analyze how rotoscoping images act as a unique role in relation with the narrative based on the said person's real stories and realistic images. I argue that his animated films constantly contain these three characteristics -Images to mediate Auditory sensitivity as a record of inner metaphysical reality, anonymous images to represent a specific existential character, and images that act as physical representation that holds the physical space/time and related memory. This reveals that rotoscoping images in this digital era went beyond reproduction for natural movements or special type of style. It rather suggests new layers of experience, and acquires new value in animation. I hope that this study could serve as a foundation to rediscover and re-position the value of rotoscoping images as well as good opportunity to introduce very talented swedish animation artist who already received global attention with his unique philosophical and aesthetic style.

  • The objective of this study is to derive key factors of commentaries in classical music concerts with commentaries and to measure the importance of each attribute, thereby presenting the characteristics of commentaries and commentators as well as suggestions to concert planners in terms of composition. In addition, by developing a scale that can measure classical commentary, a questionnaire is provided so that concert planners can plan programs that gathered the opinions of the audience. To this end, the first, second and third rounds of the Delphi survey and AHP were applied to concert planners, musicians (performing artists), and academic experts. A questionnaire was developed based on the results, and the survey was verified by conducting a pilot test with the general audience. The results of this study can be summarized as follows: First, the purpose of commentaries must be focused on arousing the audience's interest rather than on delivering information. Second, commentators must meet the auditory satisfaction of the audience with a good voice and clear pronunciation based on impeccable vocalization. Third, commentaries must be concise, with the commentaries appearing at least five times per concert, each of which must not exceed five minutes. Fourth, as a result of the pilot test, this study derived 14 items to rate commentary skills across four factors: four items for "arousing interest," three items for "delivering information," three items for "favorability," and four items for "expressiveness." Based on these results, the authors of study presented effective implications for concert planning.

  • Chinese cabbage Kimchi is a traditional fermented food and a numerous variety of Kimchies are produced in Korea. Most of Kimchis are produced on a small scale in the home for individual household use and recipes of Kimchis are deeply embedded in the individual cultures. Currently, however, factory-produced Kimchi is becoming popular by industrialization and changes of life style. This study was conducted to find out recipes of traditional Kimchis which are known delicious in Pusan and its environs and to develop a Kimchi with high quality. The characteristics of Kimchi recipes surveyed in Pusan and its environs are as follow: 1) Large amount of red pepper, garlic and anchovy sauce was used, which made Kimchi hot and spicy. 2) Extracts of dried anchovy or shrimp, or pear and onion juice was used to mix red pepper power. 3) Selection of good quality of Chinese cabbage and red pepper was very important step to determine quality of Kimchi. Furthermore, a numerous variety of submaterials added in Kimchi may also contribute to the high quality of Kimchi. 4) Salt concentration of Kimchi was around 2%, which was lower than it was generally known. Through this survey, it was suggested that maintaining low salt content of Chinese cabbage during salting make Kimchi crispy and juicy.
