Prosody Generation Based on C-ToBI Representation for Text-to-SpeechSeungwon Kim, Yu Zheng, Gary Geunbae Lee, Byeongchang KimProsody modeling is critical in developing text-to-speech (TTS) systems where speech synthesis is used to automatically generate natural speech. In this paper, we present a prosody generation architecture based on Chinese Tone and Break Index (C-ToBI) representation. ToBI is a multi-tier representation system based on linguistic knowledge to transcribe events in an utterance. The TTS system which adopts ToBI as an intermediate representation is known to exhibit higher flexibility, modularity and domain/task portability compared with the direct prosody generation TTS systems. However, the cost of corpus preparation is very expensive for practical-level performance because the ToBI labeled corpus has been manually constructed by many prosody experts and normally requires a large amount of data for accurate statistical prosody modeling. This paper proposes a new method which transcribes the C-ToBI labels automatically in Chinese speech. We model Chinese prosody generation as a classification problem and apply conditional Maximum Entropy (ME) classification to this problem. We empirically verify the usefulness of various natural language and phonology features to make well-integrated features for ME framework.

The protein profile of Synechococcus sp. cyanophage was investigated employing SDS-PAGE. The phage appears to be composed of two major proteins of 97 and 52 kDa and at least seven minor proteins of 70, 65, 60, 40, 35, 28, and 6 kDa. It seems that each subunit is combined to form a multimer although any disulfide bond does not exist in the phage structure. Lytic activity of the phage particle against cell wall was detected around the 52 kDa on renaturing SDS-PAGE using heat-killed Micrococcus luteus cells as substrate. The activity has the optimal pH between 9 and 10, and slightly inhibited by EDTA. Synechococcus sp. cyanophage의 SDS-PAGE 수행 결과 구조단백질은 두 개의 major protein(97 kDa, 52 kDa)과 최소 일곱 개의 minor protein(70 kDa, 65 kDa, 60 kDa, 40 kDa, 35 kDa, 28 kDa, 6 kDa)으로 구성되어 있는 것으로 나타났다. Subunit들은 서로 disulfide bond로 연결되어 있지는 않지만 비공유적 결합으로 multimer를 형성하여 phage particle을 구성하고 있는 것으로 보인다. 또한 heat-killed Micrococcus luteus cell을 기질로 이용한 renaturing SDS-PAGE 방법으로 phage particle내의 세포벽 분해능을 살표본 결과 52 kDa 부근에서 세포벽 분해활성이 발견되었다. 이러한 세포벽 분해활성은 최적 pH가 9~10 사이이며 EDTA에 대한 낮은 저해를 나타내었다.

In this paper, we present a phrase break prediction method using CRF(Conditional Random Fields), which has good performance at classification problems. The phrase break prediction problem was mapped into a classification problem in our research. We trained the CRF using the various linguistic features which was extracted from POS(Part Of Speech) tag, lexicon, length of word, and location of word in the sentences. Combined linguistic features were used in the experiments, and we could collect some linguistic features which generate good performance in the phrase break prediction. From the results of experiments, we can see that the proposed method shows improved performance on previous methods. Additionally, because the linguistic features are independent of each other in our research, the proposed method has higher flexibility than other methods.

A 'pusher syndrome' encompassing postural imbalance and hemi-neglect is believed to aggravate the prognosis of stroke patients. The patients with pusher syndrome show a particular posture that pushing away from the unaffected side of the body. The objective of this study was to investigate associated proprioception, associated neuro-psychological symptoms and characteristics of functional outcome with and without pusher syndrome. The subjects of this study were 58 acute stroke patients who been rehabilitated at two university hospitals in Seoul and Buchun. Data were collected using proprioception test and line bisection test. The ability of ADL was assessed by the Modified Barthel Index, transfer by the Functional Independence Measure, and balance by the Modified Motor Assessment Scale. The results were that significant difference was found in the presence of proprioception, in the incidence of hemineglect and anosognosia, and in the score of ADL, transfer and balance between patients with and without pusher syndrome. Patients without pusher syndrome gained more motor score than patients with pusher syndrome. From improvement of view, patients with pusher syndrome gained the lowest score in ability of transfer. The finding suggest that the patients with pusher syndrome is a poorer functional outcome, be related to proprioception, hemineglect and anosognosia.

Ultrasonic wave technologies have been widely used in ultrasonic washing machines, ultrasonic surgery, ultrasonic welding machines, ultrasonic sensors, and medical instruments. Ultrasonic surgery can be realized through the cavitation effect of ultrasonic waves. In this study, piezoelectric ceramics were manufactured to achieve the optimum design of a piezoelectric vibrator in a handheld generator for ultrasonic surgery. The best specimen showed the excellent piezoelectric properties of kp＝0.624, Qm＝1,531, and $d_{33}=356pC/N$. Numerical modeling based on the finite element method was performed to find the resonance frequency, the anti-resonance frequency, and the displacement properties of the handheld ultrasonic generator. Maximum displacement was observed in the six-step piezoelectric vibrator at $6.36{\mu}m$.

최근 국내외 정세의 변화와 함께 예상하지 못한 테러 등의 극한의 하중의 발생가능성이 증대하고 있다. 또한 국외 건설시장의 활성화와 함께 몇몇 중동국가를 포함하여 정세가 불안정한 국가로의 진출이 잦아지고 있어 신규 또는 기존 사회기반시설 및 건축물의 물리적인 안전성이 많이 요구되고 있다. 따라서 기존의 콘크리트나 강재로는 저항이 불가한 폭발 또는 충격하중의 저항성이 건설재료로서의 중요성이 증가하고 있는 실정이다. 본 연구는 이러한 폭발 및 충격하중에 저항하기 위한 초고성능 강섬유보강 시멘트 복합체를 개발하기 위한 기초연구로서 고혼입량의 강섬유를 우선 도포하고 내부를 충전하기 위한 슬러리의 최적배합의 결정을 위한 연구이다. 이러한 고혼입량의 강섬유의 내부를 충전하기 위한 슬러리의 기초특성을 분석하고자 재료혼입을 변수로 하여 컨시스턴시, 흐름도, J-Fiber Penetration, 블리딩 및 레올로지 특성 및 역학적 특성으로 압축강도와 휨강도를 측정하였다. As political circumstances in oversea countries and Korea varies, the risk of vulnerability from unexpected extreme loading conditions, such as explosions or extreme impacts, also increased. In addition, construction companies in Korea recently have taken chances of overseas expansion to countries where their domestic situations are not in rest. Therefore, the resistance of construction materials for blast or impact loading become taking more consideration from engineering field. This study is a part of the research to develop a high performance fiber reinforced cementitious composite materials with high volume steel fibers and primary purpose of this study is to find an optimum mix proportions of in-fill slurry. In order to accomplish the tasks this study performed experimental investigations on the slurry for consistency, compressive strength, flowability, J-penetration, bleeding and rheology properties as well as mechanical properties, compressive and flexural strength, with respect to different mix proportions.
