An increase in speech intelligibility has been found in Clear Speech compared to conversational speech. Clear Speech is defined by decreased articulation rates and increased frequency and length of pauses. The objective of the present study was to investigate improvement in immediate speech intelligibility in 10 patients with Parkinson's disease (age range: 46 to 75 years) using Clear Speech. This experiment has been performed using the Phonatory Aerodynamic System 6600 after the participants read the first sentence of a Sanchaek passage and the "List for Adults 1" in the Sentence Recognition Test (SRT) using casual speech and Clear Speech. Acoustic and aerodynamic parameters that affect speech intelligibility were measured, including mean F0, F0 range, intensity, speaking rate, mean airflow rate, and respiratory rate. In the Sanchaek passage, use of Clear Speech resulted in significant differences in mean F0, F0 range, speaking rate, and respiratory rate, compared with the use of casual speech. In the SRT list, significant differences were seen in mean F0, F0 range, and speaking rate. Based on these findings, it is claimed that speech intelligibility can be affected by adjusting breathing and tone in Clear Speech. Future studies should identify the benefits of Clear Speech through auditory-perceptual studies and evaluate programs that use Clear Speech to increase intelligibility.

Objective : analysis of words related with medical concept and context of paragraphs in Suwen of Huang Di Nei Jing based on concreteness and ideality. Method : First, I extract words having medical concept out of the whole sentence of Huang Di Nei Jing. and classifies them according to the type of medical concept. Second, I classify all sentence of it on the basis of analysing of the words. Result : 1. There are not an interrelationship between the abstract and concrete words from the perspective of cause and effect. Abstract words group are divided into two different parts according to the fundamental character. There are the concept being formed from pure idea and the concept being formed from material idea. The main words composed most important part of the oriental medicine have a combination mode with these two word groups. 2. We have several data about concreteness and ideality of Huang Di Nei Jing. Subjects and contents in provisions are concrete relatively. But the logical basis of sentences is remarkably ideational. Many kinds of abstract words are used dominantly to compose logics of these basis. It confirms that concrete words can not be used to make theories and concepts in Suwen. Conclusion : I analyzed words related with medical concept and context of paragraphs in Suwen of Huang Di Nei Jing based on concreteness and ideality and I found that the concept and logical system of Huang Di Nei Jing in the objective point of view.

An earlier study of the effect of rain found that the capacity of freeway systems was reduced, but did not address the effects of rain on the nature of traffic flows. Indeed, the substantial variation due to the intensity of adverse weather conditions is entirely rational so that its effects must be considered in freeway facility design. However, all of the data in Highway Capacity Manual(HCM) have come from ideal conditions. The primary objective of this study is to investigate the effect of rain on urban freeway traffic flows in Seoul. To do so, the relations between three key traffic variables(flow rates, speed, occupancy), their threshold values between congested and uncontested traffic flow regimes, and speed distribution were investigated. The traffic data from Olympic Expressway in Seoul were obtained from Imagine Detection System (Autoscope) with 30 seconds and 1 minute time periods. The slope of the regression line relating flow to occupancy in the uncongested regime decreases when it is raining. In essence, this result indicates that the average service flow rate (it may be interpreted as a capacity of freeway) is reduced as weather conditions deteriorate. The reduction is in the range between 10 and 20%, which agrees with the range proposed by 1994 US HCM. It is noteworthy that the service flow rates of inner lanes are relatively higher than those of other lanes. The average speed is also reduced in rainy day, but the flow-speed relationship and the threshold values of speed and occupancy (these are called critical speed and critical occupancy) are not very sensitive to the weather conditions.

Authors devised an objective test for nasal resonatory disorders using a vibratory sensor(Piezoelectric receiver) which is relatively cheap. The vibratory sensor was covered with duralumin to eliminate contamination of acoustic sound except a small hole which is attached on ala nasi during the test. Electrical signals front the vibratory sensor and the microphone while the subject is phonating vowel/a/ and nasal consonant /ng/ and phonating 8 syllable sentence /papa/ passage and /mama/ passage were digitized with n 12 bit A/D converter. For the evaluation of the hypernasality, the ratio of /ng/ to /a/ and /mama/ passage to /papa/ passage were used instead of individual values to reduce the observational error. For the evaluation of the hyponasality, the cul-de-sac resonation was induced by obstructing the nasal aperture of the ipsilateral side with the finger. In the normal control group, the ratio of /ng/ to /a/ and /mama/ passage to /papa/ passage was larger than 8. In the hypernasality with nasal emission group. the ratio was decreased markedly(p＜0.01). When the nasal aperture was obstructed with the finger, the vibratory signals of /a/ and /ng/ were increased markedly in the control group and hypernasality group(p＜0.01). However, in the hyponasality group(severe), the increment was minimal. So this system can be used to detect the nasal resonatory disorders objectively and differentiate the hypernasality front hyponasality easily.

Objective: The current study examined whether providing both an actor's eye gaze and emotional expressions can help 10-month-olds interpret a change in the actor's words as a signal to a change in the actor's goal object. Methods: Sixteen 10-month-olds participated in an experiment using the violation-of-expectation paradigm and were compared to 16 10-month-olds in a control condition. The infants in the experimental condition were familiarized to an event in which an actor looks at one of two novel objects, excitingly utters a sentence, "Wow, here's a modi!", and grasps the object. The procedure in the control condition was identical to that of the experimental condition except that the infants heard the sentence without any emotional excitement and the eye gaze of the agent was hidden by a visor. In the following test trial, the infants in both conditions heard the agent changing her word (from modi to papu) and watched her grasping either the same object as before (old-goal event) or the new object (new-goal event). Results: The infants in the experimental condition looked at the old-goal event longer than at the new-goal event, suggesting that they expected the agent to change her goal object when the actor changed her word. However, the infants in the control condition looked at the two events about equally. Conclusion: When both eye gaze and emotional cues were provided, 10-month-olds were able to exploit the agent's verbal information when reasoning about whether the agent would pursue the same goal object as before.

During adolescence the mutational period is characterized by the changes in the laryngeal structure, the length of the vocal cords, and a tone of voice. Usually, adolescents at 15 or 16 reach the voice of adults but the mutational period is sometimes delayed. Therefore, studies on the voice of adolescents between 16 ~ 18 right after the mutational period are required. Accordingly, this paper attempted to provide basic data about the normal standard for patients with voice disorders during this period by evaluating the vocal characteristics of males and females between 16 ~ 18 with an objective device bycomparing and analyzing them by sex and age. The study was conducted on a total of 60 subjects composed of each 10 subjects of each age. The vocal analysis was conducted by MPT (Maximum Phonation Time) measurement, sustained vowels and sentence reading. As for /a/ sustained vowels, fundamental frequency, hereinafter referred to as $F_0$, jitter, shimmer, noise-to-harmonic ratio, hereinafter referred to as NHR were measured by using the Multi-dimensional voice program (MDVP) among the Multi-Speech program of Computerized Speech Lab (Kay Elemetrics). The sentence reading, mean $F_0$, maximum $F_0$ and minimum $F_0$ were measured using the Real-Time Pitch (RTP) Model 5121 among the Multi-Speech program of Computerized Speech Lab (Kay Elemetrics). As a result, according to sex, there were statistically significant differences in $F_0$, jitter, shimmer, mean $F_0$, maximum $F_0$, and minimum $F_0$; and according to age, there were statistically significant differences in MPT. In conclusion, the voice of the adolescents between 16 ~ 18 reached the maturity levels of adults but the voice quality which can be considered on the scale of voice disorders showed transition to the voice of an adult during the mutational period.

Objective : Zhang zhi-cong insisted the theory related to the 'Six-meridian qi transformation', and Zhen xiu-yuan inherited that theory understanding six-meridian disease of "Shang-Han-Lun". This emphasizes that the disease of 'three yin and three yang' in "Shang-Han-Lun" is a disease caused by Six-meridian qi transformation, not a lesion of meridian itself. He said, "If you do not know brightly in the 'Tip, Root and Middle qi', you can not read the "Shang-Han-Lun"." Therefore, in this paper, we examine the interpretation of the "Shang-Han-Lun"by using the theory of 'five circuits and six qi'. Method : First, extract sentences related to 'Tip, Root and Middle qi' from the sentences of "Shang-Han-Lun" Second, the sentence is interpreted through the Zhen xiu-yuan's "Sang han lun qian zhu". Third, the meaning of the sentence is examined and summarized. Result : Zhen xiu-yuan proposed a clear and systematic theory that can understand the meaning of Six-meridian in "Shang-Han-Lun", by utilizing the discipline that 'Tip, Root and Middle qi' Conclusion : The change of 'Tip, Root and Middle qi' is a very central theory that explains the properties of 'Yin and Yang' and mutual correspondence among Korean medicine theories. It also provides basic directions for understanding the changing patterns of disease.

Document summarization is an important task in various areas where the goal is to select a few the most descriptive sentences from a given document as a succinct summary. Even without training data of human labeled summaries, there has been several interesting existing work in the literature that yields reasonable performance. In this paper, within the same unsupervised learning setup, we propose a more principled learning framework for the document summarization task. Specifically we formulate an optimization problem that expresses the requirements of both faithful preservation of the document contents and the summary length constraint. We circumvent the difficult integer programming originating from binary sentence selection via continuous relaxation and the low entropy penalization. We also suggest an efficient convex-concave optimization solver algorithm that guarantees to improve the original objective at every iteration. For several document datasets, we demonstrate that the proposed learning algorithm significantly outperforms the existing approaches.

Background and Objectives : The nasalance score measured by Nasometer is a supplementary data for the perceptually rated nasality by a trained speech pathologist. The nasalance score varies with subjects. The objective of the present study was to examine whether there are differences in nasalance scores as a function of age and sex. Materials and Method : This study used 20 normal chidren aged from 3 to 8 and 40 normal adults aged from 21 to 37(male : female= 1 : 1) as subjects. The nasalance scores were analyzed in 3 different phonetic contests(nasal, /i/ vowel,/a/ vowel) and 4 different sentence lengths(1, 2, 4, 8 syllable). Results : The children had significantly higher nasalance scores in short sentences an the adults. The female subjects had significantly higher nasalance scores in nasal sentences and in short sentences than the male subjects. Conclusion : These results may indicate that sex and age differences should be considered in the interpretation of the nasalance score in nasal sentences or in short sentences.
