The purpose of this research is to investigate how Japanese speakers perceive and produce Lenis, Aspirated and Fortis consonants in Korean. Identification tasks and production tasks were performed. The error analysis of both task showed that the participants had a significant difficulty in discriminating between Lenis and Aspirated sounds. And it was observed that there was a positive correlation between identification scores and production scores.

Sipyukmiryuki-eum (SYMYKE), Danjacheongpi-tang (DJCPT), Jipae-san Ⅰ (JPS Ⅰ), Jipae-san Ⅱ (JPS Ⅱ), and Chungganhaeul-tang (CGHUT) are representative herb-combined remedies used in traditional Korean medicine for treating breast cancer patients, as mentioned in "Dongeuibogam." In this study, we investigated the total phenolic contents (TPCs) and the anti-oxidant and anti-microbial activities of hot water and 70% ethanol extracts of these herbal prescriptions. Among the five herb-combined remedies, the extraction yields of the hot water extracts and 70% ethanol extracts were the highest in JPS Ⅱ (34.30%) and DJCPT (30.50%), respectively. The TPCs of the hot water extracts from the herb medicines were rich in the order of JPS Ⅰ < CGHUT < JPS Ⅱ < SYMYKE < DJCPT. In addition, the 70% ethanol extracts from the herb medicines were rich in the order of JPS Ⅱ < JPS Ⅰ < CGHUT < SYMYKE < DJCPT. Among them, DJCPT and SYMYKE displayed a strong anti-oxidant capability, which was determined using ferric-reducing anti-oxidant power and scavenging of 2,2'-diphenyl-1-picrylhydrazyl and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonate) cationic radical activity assays. In addition, anti-microbial activities against Staphylococcus aureus and Escherichia coli were stronger in the 70% ethanol extracts than in the hot water extracts. Together, these findings reveal a positive relationship between TPCs and their anti-oxidant activities.

제품의 음질 특성과 관련된 주요 주파수 대역을 파악하기 위해 본 연구에서는 청소기 소리의 주파수 대역을 음성인식에 중요한 주파수 대역인 4개의 대역으로 나누고, 각 대역 성분을 직교배열표에 따라 가감한 16개의 소리를 만들었다 만들어진 소리에 대해 10명을 대상으로 4가지의 표현어로 Semantic Differential Method(SDM)로 주관적 평가를 하여, 청소기음의 주파수 특성과의 상관관계를 살펴보았다. 불쾌한 느낌과 관련이 깊은 주파수 대역은 고주파수 대역이었으며, 성능이 좋은 느낌을 주기 위해서는 저주파수 대역을 증가시키는 것 이 효과적이었다.

The indented geometry for rockwell hardness indenter has been configured by using Confocal Laser Scanning Microscopy (CLSM). For this purpose, the CLSM can be well suited to construct the three-dimensional indented volume from the indented surface by rockwell hardness tester. Furthermore, the height data of HEI(height encoded image) by CLSM must be acquired at first and converted to indented surface later. And the indented surface patterns enable us to predict the indenter shape and volume. This volume can be used to study the rockwell hardness model as a volume parameter. As a result, the technique performed in this study by combining the CLSM with compensation technique is an excellent one to obtain the geometries of indented surfaces over a wide range of surface resolution in a micro scale. And it can be used for micro volume calculation.

In this study, we investigated the antioxidant activities and compared other physiological properties including anti-cancer and antimicrobial effects of several traditional Korean herb-combined remedies such as Gilgyung-tang (GGT), Daihwangmokdan-tang (DHMDT), Sagan-tang (SGT), Socheonryongtang (SCRT), Sihocheonggan-tang (SHCGT), Sipyukmiyuki-eum (SYMYKE) and Hwangheuk-san (HHS), which were recorded in “Dong-eui-bo-gam” for “Ongjeo”. Total phenolic contents of the herb medicines were in a rich order of GGT ＜ SYMYKE ＜ SCRT ＜ SHCGT ＜ DHMDT ＜ SGT ＜ HHS. Among them, HHS appeared highest in superoxide dismutase-like activity, ferric reducing antioxidant power, scavenging of 2,2’-diphenyl-1-picrylhydrazyl, and 2,2’-azinobis(3-ethylbenzothiazoline-6-sulfonate) cationic radical activity. Interestingly, there was a positive relationship between their total phenolic contents and their antioxidant activities. Although all of them showed anti-proliferative activities in human colon cancer HCT-116 cells, HHS was seven times higher than GGT. Antimicrobial activities against Escherichia coli and Helicobacter pylori were revealed only on SGT, SCRT, SYMYKE and HHS. Taken together, these findings reveal the potential use of traditional Korean herbal formulas as functional ingredients in antioxidant and physiological materials.

This study investigated whether Korean learners improve acoustic cue weights to identify Korean lenis and aspirated stops in the direction of native values through perception training that focused on contrasting the stops in various phonetic contexts. Nineteen native Chinese learners of Korean and two native Korean instructors for the perception training participated in the experiment. A training group and a non-training group were divided according to pretest results, and only the training group participated in the training for 5 days. To estimate the perceptual weights of the stop cues, a pretest and a posttest were conducted with stimuli whose stop cues (F0 and VOT) were systematically manipulated. Binary logistic regression analyses were performed on each learner's test results to calculate perceptual β coefficients, which estimate the perceptual weights of the acoustic cues used in identifying the stop contrast. The training group showed a statistically significant increase of 0.451 on average in the posttest for the coefficient values of the F0, which is the primary cue for the stop contrast, whereas the non-training group showed an insignificant increase of 0.246. The patterns of change in the F0 use after training varied considerably among individual learners.

This study was performed to evaluate the effect of Kami-bun-sim-ki-eum on irritable bowel syndrome and to find the factors valuable to diagnosis of symptom-complex of them. Four major sympoms were classified in all 31 paients(female 17, male 14), which was index of abdominal, fecal, autonomic dysfunction, and gastric dysfucton and pain severity score method was used in monitoring with the effect of Kamibun-sim-ki-eum on irritable bowel syndrome before and after adminstration of 2 packs I day for 10 days. We have found that Kami-bun-sim-ki-eum was effective only in female group ,but not in male and only sex factor was recognized significantly among factors to have influenced the effect of Kami-bun-sim-ki-eum. Rate of improvement was mean 61% in female, accompanied with improvement of each symptom after administration. Therefore, we have concluded that Kami-bun-sim-ki-eum can be applyed as one of an choice medicines in treating female irritable bowel syndrone.

Objective: Graves' disease encompasses hyperthyroidism and diffused goiter associated with auto-antibodies to the thyroid stimulating hormone(TSH) receptors. In clinical environment, treatments of Graves' disease have many side effects such as recurrence and hypothyroidism. We've studied the effects of Sipyukmiyukieum on DNA synthesis, cAMP synthesis, and MHC-class II expression of FRTL-5 thyroid cells were studied. Methods: DNA synthesis was investigated by using BrdU staining and cAMP synthesis by ELISA kit, and expression of $interferon-{\gamma}$ activated MHC class II by Flow cytometer. Results: After introduction of Sipyukmiyukieum, significant inhibition of DNA synthesis. cAMP synthesis, and expression of $interferon-{\gamma}$ activated MHC class II of FRTL-5 thyroid cells was observed. Conclusions: Judging from these results, Sipyukmiyukieum has potential as a potent herbal treatment for inhibiting the enlargement of goiter, synthesis of abnormal thyroidal hormones, and autoimmuine responses of Graves' disease.

Objectives : The aim of this study was to evaluate the effects of Punsimgi-eum(fenxingi-yin) in rat model of depression induced by chronic mild stress (CMS). Methods : The change of the consumption of sucrose solution was measured, and the open field test and passive avoidance conditioning test were performed to investigate the anti-depressive effect of Punsimgi-eum(fenxingi-yin). Results : The results were as follows; I. The consumption of sucrose solution was significantly reversed in the test group at 5, 7 and 8 weeks, but there was no significant change in the control group. 2. There was no significant change of body weight after 8 weeks in each group 3. In the open field test, there was significant increase of exploratory activity in the test group. 4. In the passive avoidance test, the test group showed differences in the maintenance of retention from the control group at the 2-week training-testing interval. Conclusions : The present results suggest that Punsimgi-eum(fenxingi-yin) has an anti-depressive effect.
