  • This study attempts to investigate the contribution of prosody to the foreign accent in Chinese speakers' English production by examining the synthesized speech of crossing native and non-native talkers' prosody and segments. For the stimuli of the foreign accent ratings, we transplanted gender-matched native speakers' prosody onto non-native talkers' segments and vice versa, utilizing the TD-PSOLA algorithm. Eight English native listeners participated in judging foreign accent and comprehensibility of the transplanted stimuli. Results showed that the synthesized stimuli were perceived as stronger foreign accent regardless of speakers' proficiency when English speakers' prosody was crossed with Chinese speakers' segments. This suggests that segments contribute more than prosody to native listeners' evaluation of foreign accent. When transplanted with English speakers' segments, Chinese speakers' prosody showed a difference in duration rather than pitch between high and low proficiency such that stronger foreign accent was detected when low proficient Chinese speakers' duration was crossed with English speakers' segments. This indicated that prosody, more specifically duration, plays a role though the prosodic role is not overall as significant as segments. According to the post acoustic analysis, the temporal features contributing to making the duration parameter prominent as opposed to pitch were found out to be speaking rate, pause duration and pause frequency. Finally, foreign accent and comprehensibility showed no significant correlation such that native listeners had no difficulty listening to highly foreign accented speech.

  • We propose a target identification algorithm for visual tracking. Target identification is realized by finding out corresponding line segments to the hypothesized model segments of the target. The key idea is the combination of the Mahalanobis distance with the geometrical relationship between model segments and extracted line segments.

  • This study classifies consumers according to apparel shopping values to find the differences of apparel attributes in accordance to shopping value segments between Korean and Chinese college students. College students from Seoul and Beijing participated in the study and a quota sampling method collected the data. Data from 504 questionnaires is used for the statistical analysis. A factor analysis through, Cronbach's alpha coefficient, ANOVA, and a post-hoc test are conducted. Two factors of apparel shopping values are classified (hedonic shopping values and utilitarian shopping values). Four segments of apparel shopping value were classified (hedonic shopping, low involvement shopping segment, high involvement shopping, and utilitarian shopping). Three factors of apparel attribute are classified (external attributes, internal/aesthetic attributes, and internal/quality attributes). The result indicate that high involvement shopping segments considered all the clothing attributes more importantly than the other three segments. Chinese respondents of hedonic shopping segments and high involvement shopping segments considered advertisements in terms of external attributes, assembly, and fit in terms of internal/quality performance attributes as more important than Koreans. Chinese respondents of low involvement shopping segments also considered assembly and fit in terms of internal/quality performance attributes as more important than Koreans. Korean respondents of utilitarian shopping segments had a special regard for design and color in terms of internal/aesthetic attributes but the Chinese had a special regard for assembly, fit, and ease of maintenance in terms of internal/quality performance attributes.

  • A new algorithm is proposed for the extraction of line segments to construct 3D wire-frame models of building from the high-resolution aerial images. The purpose of this study Is the accurate and effective extraction of line segments, considering the problems such as discordance of lines and blurred edges existing in the conventional methods. Using the edge map extracted from aerial images, chain code tracking of edges was performed. Then, we extract the line segments considering the strength of edges and the direction of them. SUSAN (Smallest Uni-value Segment Assimilating Nucleus) algorithm proposed by Smith was used to extract an edge map. The proposed algorithm consists of 4 steps: removal of the horizontal, vertical and diagonal components of edges to reduce non-candidate point of line segments based on the chain code tracking of the edge map, removal of contiguous points, removal of the same angle points, and the extraction of the start and end points to be line segments. By comparing the proposed algorithm with Boldt algorithm, better results were obtained regarding the extraction of the representative line segments of buildings, having relatively less extraction of unnecessary line segments.

  • The purpose of this study was to investigate change of mechanical energy before and after training of half vinyasa yoga. Thirteen subjects (height: $163.4{\pm}3.9$ cm, body mass: $54.9{\pm}7.3$ kg, age: $20.0{\pm}0.49$ yrs) participated in this experiment. The motions of half vnyasa yoga were captured with Vicon system and parameters were calculated with Visual-3D. After training of half vinyasa yoga, the mechanical energies of body segments were increased and increments of mechanical energies in the lower segments were greater than the upper segments. The phase increments of mechanical energies increased phase 1, phase 2, and phase 3 in order. After training of half vinyasa yoga, phase contributions of body segments were similar before training of half vinyasa yoga. The contribution of mechanical energy on trunk segment in body was the greatest contribution of upper segments; also that of mechanical energy on thigh segment in body was the greatest contribution of lower segments. Before training, the coefficient of correlation between vertical center of gravity (CoGz) and mechanical energy of phase 3 was a -.559, but after training, the coefficient of correlation between CoGz and mechanical energy of phase 2 was a .587. These findings suggest that the training of half vinyasa yoga may be increasing the mechanical energies of body segments.

  • The purpose of this study is to compare the 3-dimensional MR angiography(MRA) with digital subtraction angiography(DSA) for the evaluation of pedal artery. MR angiography was performed using three-dimensional FISP acquisition before, and four sequential acquisitions after the injection of gadolinium(0.2 mmol/kg, 3 ml/sec). MRA was compared with DSA for a correct identification of the arterial segment. Out of 168 segments, 32 segmints were invisible in both MRA and DSA. At the level of ankle, 48 segments were visible in both examinations, and 18 segments were visible only in MRA. In the foot area, 34 segments were visible in MRA, but not in DSA. Three arterial segments were visible only in DSA. 3D MRA is comparable to DSA for the evaluation of pedal artery, thus it gives additional Information for the planning of treatment in lower extremity artery.

  • Effects of IAA on the elongation and cell wall hlysocidase activities were investigated in excised rape (Brassica napus L. cv. Yongdang) hypocotyl segments. IAA promoted the elongation of rape hypocotyl segments. In rape hypocotyls, the first 10-mm segments from the hook exhibited maximal elongation and the capacity of elongation was gradually decreased with increasing distance of each 10-mm from the hook. A good correlation has been obtained between the magnitude of endogenous growth and the activities of $\alpha$, $\beta$-glucosidase and $\alpha$, $\beta$-galactosidase. However, exogenous application of IAA did not seem to enhance the tissue with IAA resulted in acidification of the incubation medium. From these data, we can conclude that IAA seems to enhance elongation of the tissue segments, at least in part, by releasing hydrogen ion into cell wall, some of which may participate in the cell wall extension process, but does not seem to trigger the activation of $\alpha$, $\beta$-glucosidase and $\alpha$, $\beta$-galactosidase.

  • Polyamine titers and the activities of arginine decarboxylase(ADC) and ornithine decarboxylase (ODC), enzymes which catalyze rate-limiting steps in polyamine biosynthesis, were investigated during polar regeneration of Populus leaf segments. The polar regeneration occurred at the basal cut end of Populus leaf segments through cell division around the vascular bundle. In the process of polar regeneration, the titers of putrescine and spermidine increased rapidly but the content of spermine remained constant. The leaf segments were then divided into three separte part ; the proximal, middle and distal. Spermidine titers showed an increase mainly in the proximal parts where polar regeneration occurred. On the other hand, putrescine titers showed an increase in the other two parts. In the course of polar regeneration, the activities of ADC and ODC increased, the ADC activities being higher than those of ODC. However, ODC activity was higher in the proximal part. Therefore, the spermidine contents and ODC activities are suggested to be related to polar regeneration in Populus leaf segments.

  • This pilot study aimed to set up a reasonable method for measuring body segments parameters and finding out some useful body segments parameters to diagnose Sasang constitutions. In this study, we have tried to take a secure effort in measuring and diagnosing of Sasang constitutions based on the consensus among Sasang constitution experts. And we also have tried to find out some useful body segments parameters based on the actual data. We measured 9 clinically meaningful body lengths specified by Sasang constitution experts and analyzed these parameters statistically according to each Sasang constitution. We have found that Taeeumin female's ratio of foot length to height was significantly large and Soyangin's ratio was significantly small, but more data are needed to confirm this finding.

  • Bronchiectasis is an irreversible dilatation that may require surgery for successful treatment. We compared High Resolutional Computed Tomography[HRCT]with Bronchography to access the utility of HRCT in diagnosis and determining the extent of Bronchiectasis. We performed a comparative study of HRCT and Bronchography in 10 consecutive patients who were clinically suspected Bronchiectasis were investigated prospectively during last year.A segment-by-segment analysis of the presence, extent, type of bronchiectasis by Amashita classification was done. In 26 segments, Results of HRCT and Bronchogram were both positve, and 119 segments were both negative.But 15 segments were discorded, in 11 segments in positive bronchogram were negative in HRCT and 4 segments in positive HRCT were negative in bronchogram. The diagnostic concordance rate between 2 modalities was 90.6%[145/160]. So, we will be tried to elevate of concordance rate between 2 modalties and applied HRCT in diagnotic tool for bronchiectasis.
