  • This study was carried out to evaluate the quality characteristics of cookies added with various concentrations (0, 1, 3 and 5%) of ginseng leaf powder. The pH of the cookies significantly decreased with increased ginseng leaf powder concentrations (p<0.05), but the density of cookies showed no significant differences. Spread factor, loss rate, and leaving rate of cookies decreased according to the amount of added ginseng leaf powder. The lightness and yellowness of cookies decreased as the concentration of the ginseng leaf powder increased whereas no significant difference in the redness was found with increased ginseng leaf concentration. In the texture analysis, the hardness of the cookies increased according to the concentration of ginseng leaf. DPPH free radical scavenging activity of the cookies significantly increased with increased ginseng leaf concentration (p<0.05). In the sensory evaluation, sensory scores for color, taste and overall acceptability were highest in the 3% ginseng leaf cookies. Thus, our results suggested that the optimum amount of ginseng leaf powder to add to cookies was 3%.

  • The effects of added brown rice flour on the quality characteristic of waffle were investigated. Waffle were prepared by the addition of 0%, 25%, 50%, 75% and 100% of brown rice flour on wheat flour. The weight of waffle with brown rice flour ranged from 103.0~107.0 g and that of the control was 100.0 g. The volume of the waffle prepared by adding brown rice flour were 225.0~303.0 mL and that of the control was 307.5 mL. The weight of the waffle increased with increasing brown rice flour concentration, whereas volume and baking loss decreased. The hardness, chewiness (p<0.05) and springiness decreased with the addition of brown rice flour. The Hunter L values of waffle decreased, whereas a and b values increased with the addition of brown rice flour. The result of the sensory evaluation showed that taste and overall acceptability (p<0.05) was the highest for added brown rice flour.

  • Schwannomas, which originate from Schwann cells in the peripheral nervous system, are slowg-rowing and uncommon benign tumors. Most schwannomas (90%) occur in isolation, and multiple occurrences are a characteristic feature of neurofibromas. Schwannomas of the nose and nasal tip are particularly unusual. Although a few cases of schwannomas of the sinusoidal tract and nasal septum have been reported, schwannomas arising from the nasal dorsum area and tip are extremely rare. Sensory abnormalities are also a very rare symptom. We excised a schwannoma on the nasal dorsum through direct incision and a schwannoma on the nasal tip through open rhinoplasty. No postoperative complications involving recurrence, hematoma, or infection occurred. The possibility of neurological changes should be considered in cases of an abnormality in the peripheral nervous system. Schwannoma must be kept in mind as a possible cause of neurological changes localized to a specific dermatome, and should always be considered in the differential diagnosis of a mass on the nose.

  • The proximate composition, quality characteristics, antioxidant activity, and sensory evaluation scores of yakgwa added with mealworm powder (MP) were examined. MP contained 5.83 wt% moisture, 55.70 wt% crude protein, 35.96 wt% crude fat, 3.70 wt% crude ash, and 2.43 wt% carbohydrate and feature total polyphenol and flavonoid contents of 406.52 mg GAE/100 g and 21.18 mg NE/100 g, respectively. The DPPH and ABTS•+ radical scavenging activities and the reducing power of MP were determined as 90.25%, 44.06%, and 1.74, respectively. Except for moisture and carbohydrate content, the proximate composition of mealworm yakgwa (MY) increased with the amount of MP increased. The pH of the dough increased with the addition of MP, whereas the expansion degree tended to decrease. Sugar content was highest at MP contents of 0 wt% and 12 wt% (FM4 group), and hardness was lowest in the FM4 group. With the increasing MP content, the L, b values and antioxidant activity increased, whereas a value decreased. The sensory evaluation scores for the overall preference, appearance, color, and taste were lowest in the FM4 group. These results suggested that MP contents of 6-9 wt% were optimal for mealworm-based yakgwa.

  • This study investigated the effect of added freeze-dried mulberry fruit juice (FDMJ) (1, 3 and 5%) on the antioxidant activity and fermented characteristic of yogurt during refrigerated storage. A decrease in pH of yogurt and increase in acidity was observed during fermentation. The yogurts with FDMJ exhibited faster rate of pH reduction than control. Initial lactic acid bacteria count of yogurt was 6.49-6.94 Log CFU/g and increased above 9 Log CFU/g in control and 1% in FDMJ yogurt for 24 h. The total polyphenol and anthocyanin content of FDMJ yogurt was higher than that of control due to the presence of phytochemical contents in mulberry. Moreover, antioxidant activity such as DPPH and reducing power was highest 5% FDMJ yogurt. During cold storage, pH decreased or remained constant in all yogurts with values ranging from 4.08 to 4.78 units. In sensory evaluation, the score of 1% FDMJ yogurt was ranked higher when compared with other yogurts. It is proposed that mulberry fruit juice powder can be used to improve sensory evaluation and enhance functionality of yogurt.

  • Nerve conduction study (NCS) is an electrophysiological tool to assess the overall function of cranial and peripheral nervous system, therefore NCS has been diagnostically helpful in the identification and characterization of disorders involving nerve roots, peripheral nerves, muscle and neuromuscular junction, and are frequently accompanied by a needle Electromyography. Furthermore, NCS could provide valuable quantitative and qualitative results into neuromuscular function. Usually, motor, sensory, or mixed nerve studies can be performed with using NCS, stimulating the nerves with the recording electrodes placed over a distal muscle, a cutaneous sensory nerve, or the entire mixed nerve, respectively. And these findings of motor, sensory, and mixed nerve studies often show different and distinct patterns of specific abnormalities indicating the neuromuscular disorders. The purpose of this special article is to review the neurophysiologic usefulness of NCS, to outline the technical factors associated with the performance of NCS, and to demonstrate characteristic NCS changes in the setting of various neuromuscular conditions.

  • The purpose of this study was to investigate the quality characteristics of Bokbunja-Pyun, using various levels of Rubi fruit juice (0%, 4%, 6% and 8%). The chemical composition and physical characteristics of Bokbunja and Bokbunja-Pyun were analyzed and sensory evaluation was conducted. The statistical data analyses were completed using the SPSS program. The chemical components of Bokbunja were moisture 89.2%, sweetness 9.8 Brix%, pH 3.77, citric acid 8.98%, and vitamin C 26mg. The L-value of Bokbunja-Pyun was significantly decreased (p<0.001), but a- and b-values were increased with increasing Rubi fruit juice content (p<0.001). Among the mechanical characteristic, the hardness was the highest on R2 ($470{\pm}82.67$), the adhesiveness on R3 ($-5.00{\pm}1.0$), the cohesiveness on R4 ($99.22{\pm}6.95$) and the gumminess on R1 ($167.9{\pm}49.8$). The springiness was notsignificantly different between these groups. From the sensory evaluation, appearance, hardness, and flavor showed no significant variation, but transparency, elasticity, and overall quality were significantly different between the test groups. It was concluded that the optimum content of added of Rubi fruit juice was 6%, in proportion to the total weight.
