  • Hearing organs have unique characteristics and have a role in processing external sensory signals. Sensory hair cells and nerve fibers in the organ of Corti can be damaged by various causes and they do not regenerate themselves. Medication used for clinical treatment for the inner ear is limited due to the anatomical structure of the inner ear. Photobiomodulation (PBM) is a therapeutic approach that uses various sources of light and the success of PBM therapy is highly reliant on the parameters of the light sources. The positive effects of PBM have been reported in various clinical fields. This paper summarizes the previously reported research on PBM for the treatment of hearing damage in animal models.

  • The purpose of this study was to replace the highly imported wheat consumption with rice in order to improve the rate of food self-sufficiency. Also, the study focused on the possibility of compounded bread making with rice flour, its taste for the Korean who have westernized eating styles, and the development of rice flour compounded bread as an alternative for wheat allergic people. Therefore, the researcher produced the soaked-rice flour, toasted-rice flour, and Extrusion-Expansion of Rice (E-ER) flour by different processing methods to bake rice wheat bread with the 10~50% mixing proportion. The volume and structure of bread were observed with Scanning Electron Microscope (SEM), and the sensory quality and the baking property were analyzed with a seven-point Likert type scale of Quantitative Descriptive Analysis (QDA). The sensory quality consisted of seven qualities such as color, size and distribution of air cell, flavor, softness, chewing, and overall quality that were evaluated as higher rating showed the better quality. The results of this study are: 1. The volume of the three types of rice wheat bread was almost same or bigger than wheat bread with the 20% of mixed proportion. 2. The size and distribution of air cell of E-ER wheat bread observed by SEM were more evenly distributed that toasted-rice wheat bread. The E-ER wheat bread had soft structure and was relatively similar to wheat flour bread. However, the structure of soaked-rice wheat bread was significantly different to other types of rice wheat bread. The structure of 10% mixed all three types of rice wheat bread was similar and evenly distributed to wheat bread but was bigger and coarser as higher mixing proportion of rice flour. 3. The dark brown color of rice wheat bread showed low sensory quality. 4. Both soaking-rice flour and E-ER flour were able to be mixed with wheat flour up to the 50%, and the seven sensory quality of these wheat bread were better than those of wheat bread. Among the three types of rice flour, toasted-rice wheat bread showed low bread property and sensory quality compared to soaked-rice or E-ER wheat bread. Consequently, this study showed that rice wheat bread that contains 20~30% of rice flour was better than wheat bread in the appropriate volume, seven sensory qualities and bread property.

  • Optimal conditions for processing. of seasoned-dried Pacific saury treated with liquid smoke (T2) were evaluated by physicochemical and microbial experiments and sensory evaluation, comparing with control (seasoning only, C) and treatment I $(0.05\%\;Rosemary\;instead\;of\;liquid\;smoke,\;Tl)$. Two hrs of seasoning time was set, and 23 hrs of drying time was determined in all samples. Finally, T2 product was made by soaking treatments (three times of 1 sec, 8 sec and 1 sec) in $5\%$ (v/v) liquid smoke (Scansmoke PB 2110) after 30 min, 4 hrs and 22 hrs of hot-air drying, respectively. The histamine contents in 3 seasoned-dried products were in a 15.33-26.99 mg/l00g range. The water activities of 3 seasoned-dried products were 0.719-0.735 range, and the pH of T2 was lower than the others. In the comparison of POV and TBA values among products, the TBA values and POV of Tl and T2 were significantly low compared to C, and also the viable cell counts of T2 was relatively lower than those of the others. In the color values, significant changes were not found among products, and in the sensory evaluation for odor, taste and overall acceptance, T2 had relatively higher preference on the whole items.

  • Purpose: This study was to investigate the quality characteristics of wet noodle added with radish juice containing with pulp. Methods: Wet noodles were prepared with different amounts of radish juice (0%, 20%, 40%, 60%, 80%, 100%, w/w) instead of water. Results: As the amount of radish juice was increased, water absorption, volume increasing rate, and turbidity of soup were decreased. Lightness (L) values of uncooked wet noodles and cooked noodles were decreased with the addition of radish juice, while redness (a) and yellowness (b) values had no tendency of increasing or decreasing, regardless of the amount of radish juice. Moreover, lightness, redness, and yellowness values of uncooked noodles were higher than those of cooked noodles. The texture of cooked noodles showed significant differences in hardness and chewiness. It was increased as the amount of radish juice was increased. Their adhesiveness and springiness were lower than those of the control. Appearance, texture, and overall acceptability of sensory evaluation revealed that the noodle added with 80% of radish juice had the highest scores, although there were no differences among noodles added with different amounts of radish juice. Conclusion: In summary, the most desirable blending ratio of radish juice and water for the kneading of wet noodles was 80:20.

  • Purpose: This study was designed to elucidate the energy-utilization patterns for five methods of robo production. Methods: Robo (fried melon cake) was produced using five different methods, and the energy used for each unit operation was calculated using standard equations. The sensory attributes of the products were determined by panelists. Data were analyzed using descriptive analysis and analysis of variance at p < 0.05. Results: The energy demands for processing 2.84 kg of melon seed into robo (fried melon cake) using processes 1 (traditional method), 2, 3, 4, and 5 (improved methods) were 50,599.5, 21,793.6, 20,379.7, 21,842.9, and 20,429.3 kJ, respectively. These are equivalent to energy intensities of 1,7816.7, 7,673.8, 7,175.9, 7,691.2, and 7,193.4 kJ/kg, respectively. For the traditional process, the frying operation consumed the highest energy (21,412.0 kJ), and the mixing operation consumed the lowest energy (675.0 kJ). For the semi-mechanized processes, the molding operation consumed the highest energy (6,120.0 kJ), and the dry milling consumed the lowest energy (14.4 kJ). Conclusions: The energy-consumption patterns were functions of the type of unit operation, the technology involved in the operations, and the size of the equipment used in the whole processing operation. Robo produced via the milling of dried melon seed before oil expression was rated highest with regard to the aroma and taste quality, as well as the overall acceptability of the sensory evaluation, and required the lowest energy consumption. Full mechanization of the process line has potential for further reduction of the energy demand.

  • This study evaluated the effect of vacuum and modified atmosphere (40% $CO_2+60%$ $N_2$, MA) packaging on the chemical composition, physicochemical properties and sensory attributes of chill-stored meat from 10 fallow deer (Dama dama) bucks at 17 to 18 months of age. The animals were hunter-harvested in the forests of north-eastern Poland. During carcass dressing (48 to 54 h post mortem), both musculus longissimus muscles were cut out. Each muscle was divided into seven sections which were allocated to three groups: 0, A, and B. Samples 0 were immediately subjected to laboratory analyses. Samples A were vacuum-packaged, and samples B were packaged in MA. Packaged samples were stored for 7, 14, and 21 days at $2^{\circ}C$. The results of the present study showed that the evaluated packaging systems had no significant effect on the quality of fallow deer meat during chilled storage. However, vacuum-packaged meat samples were characterised by greater drip loss. Vacuum and MA packaging contributed to preserving the desired physicochemical properties and sensory attributes of meat during 21 days of storage. Regardless of the packaging method used, undesirable changes in the colour, water-holding capacity and juiciness of meat, accompanied by tenderness improvement, were observed during chilled storage.

  • These studies were carried out to investigate the quality of green tea processed by different pan-firing hand rolling and to select the best conditions during the procedure of green tea processing the results were as follows. At harvestion tea plant leaf, tea plants had 4 leaves. each leaf size was 7.5 cm'$\square$2.6 cm, and weight of 100 buds 46.6 g. The increase of pan-fired time decreased in the moisture content and yield of green tea. After processing green tea, 5 times pan-fired one had much more contents of total nitrogen (T-N:5.31%), caffeine (2.00%) and total amino acid (T.A.A. : 3,046 mg%) and less content of tannin (13.41%) than the other treatments. but 3 times pan-fired one had the highest contents of vitamin C (204.3 mg%) and chlorophyll (365.0 mg%) among three kinds pan-firing method. Sixteen kinds of free amino acid including theanine as a good taste component of pan-fired green tea were isolated and measured by HPLC. Free amino acid (FAA) contents were in the range of $2,683{\sim}2,925$ mg% and among various pan-firing methods, 5 tims pan-fired one had the highest content of F.A.A. Among these free amino acids, theanine occupied as much as $56.4{\sim}61.3%$ of F.A.A. Lightness, yellowness and redness of 5 times pan-fired green tea were middle value among three different treatments. Besides, it gained the highest score of sensory evaluation among them. These above results suggested that 5 times pan-fired green tea was considered to be the best level as pan-firing times of green tea processing.
