This paper investigates that the ambiguity of the boundary between interior space and exterior space in architecture appears universally in history and reveals the various aspects of ambiguous boundary in architecture. The space is formed by the relationship with the surroundings and the boundary of two opposite spaces is apt to be ambiguous according to lots of complex factors. Before Modern Architecture the boundary of interior and exterior space had a tendency to be ambiguous by modifying compositional method of material boundary, that is semi interior-exterior space, the reversion of interior and exterior space and space in space. After Modern Architecture the meaning of physical boundary in space is lost along with dissolution of boundary over the society and the boundary of space comes to be dematerialized by the technology and the change of space perception. The phenomenon of deconstruction in spacial boundary accelerate increasingly according to fluid space, mutually interpenetrated space, visual transparency and adjustment of layers. And contemporary technology is collapsing the meaning itself of space division fundamentally.

The current study reports the results from a cross-modal naming experiment investigating the effects of a prosodic boundary location on the comprehension of ambiguous dative NPs in Korean (Yeongmi-ka Ceonghi-eykey norae-rul pwulecwu-n pwuin-ul ${\cdots}$). The underlined dative NP, Ceonghi-eykey, can temporarily be attached to the embedded rel-marked verb, pwulecwu-n ('sing-rel') or to the matrix verb to appear later. Participants heard sentence fragments manipulated for the location of Intonation Phrase boundary (the biggest prosodic boundary in the model of Seoul Korean) and right after that, had to name visually presented naming targets, which resolve the ambiguity of dative NPs. The prosodic manipulation did not result in difference in naming time, suggesting that the location of a prosodic boundary failed to influence the way Korean listeners interpreted ambiguous dative NPs. Possible reasons for the null effect were discussed.

The prosody can play a crucial role in differentiating ambiguous sentences to correctly reflect their intended syntactic structures. In what way do the speakers in Tokyo and Sendai dialects of Japanese use prosodic elements to differentiate syntactic ambiguities? Acoustic measurement was made of utterances of ambiguous sentences in Japanese to observe prosodic strategies for disambiguation. Materials were sentences of the type ADV-VP1-NP-VP2, ADV-NP1-NP2-VP2, where the ambiguity lies in locative adverbial modification, ADV modifying either VP1 or VP2. For this construction the Japanese create the same ambiguities. After defining the depth of a syntactic boundary, F0 of the phrase before and after the boundary, and duration of the syllable and pause before the boundary were measured. The results show that Tokyo dialects speakers use F0 after syntactic boundary, and Sendai dialects speakers use of the syllable and/or pause before the boundary.

'Boundaries' are divided in various types and expressed in diverse ways. Since the progress of socio-cultural, scientific, technological and ideological changes has been so fast, spaces, including cities and their architecture, are also changing rapidly. It is really hard to catch the general flow of modern architectural situations and the logic behind them since they are very complicated and diverse. It is even more complicated to determine which architectural phases represent the same period and how to provide the accompanying characteristics. Therefore, in this study, the boundary has infinite possibilities. By how to provide the accompanying characteristics. Therefore, in this study, the boundary has infinite possibilities. By reorganizing the structure of the ambiguous boundary and what the ambiguous boundary means itself in the process of thinking of creative designers as well as encompassing spatial design. This study will suggest a formative possibility that can be applied as space.

This experimental study has a goal to explore the perceptual sensitivity to phonetic evidence such as duration, phrase accent, or pause in disambiguation. We argue that the realization of the intonational phrasal boundary at the meaningful grammatical boundary in structurally ambiguous sentences facilitates English native listeners to distinguish the meanings of the ambiguous sentences. Moreover, the duration of the phrase-final syllable, pitch range reset, or phrasal tones also provides listeners with important phonetic evidence in disambiguation. In our perception experiment, however, Korean English learners largely depend on the realization of pause. In the results from the perception experiment, all of the groups showed an increase in the response time from the perception of no pause to pause realization. This means that pause at the phonological phrasal boundary plays a role of facilitator to English native speakers with other prosodic cues such as duration, pitch accent, or phrasal tones, while an absolutely important cue to Korean English learners.

본 논문은 공간 부호화 패턴들을 이용하여 3차원 얼굴 정보를 정확하게 측정하기 위하여 초기 얼굴 패턴 영상으로부터 이미지 패턴을 검출하기 위한 새로운 알고리즘을 제안한다. 획득된 영상이 불균일하거나 패턴의 경계가 명확하지 않으면 패턴을 분할하기가 어렵다. 그리고 누적된 오류로 인하여 코드화가 되지 않는 영역이 발생한다. 본 논문에서는 이러한 요인에 강하고 코드화가 잘 될 수 있도록 FCM 클러스터링 방법을 이용하였다. 패턴 분할을 위하여 클러스터는 2개, 최대 반복횟수는 100, 임계값은 0.00001로 설정하여 실험하였다. 제안된 패턴 분할 방법은 기존 방법들(Otsu, uniform error, standard deviation, Rioter and Calvard, minimum error, Lloyd)에 비해 8-20%의 분할 효율을 향상시켰다.

Cardiac function is evaluated quantitatively using angiographic images via the analysis of the shape change or the heart wall boundaries. To kin with, boundary defection or ESLV(End Systolic Lert Ventricular) and EDLV(End Diastolic Left Ventricular) is essential for the quantitative analysis of cardiac function. The boundary detection methods proposed in the past were almost semi-automatic. Intervention by a knowledgeable human operator was still required Of con, manual tracing of the boundaries is currently used for subsequent analysis and diagnosis. This method would not cut excessive time, labor, and subjectivity associated with manual intervention by a human operator. EDLV images have noncontiguous and ambiguous edge signal on some boundary regions. In this paper, we propose a new method for automated detection of boundaries in noncontiguous and ambiguous EDLV images. The boundary detection scheme which based on a priori knowledge information is divided into two steps. The first step is to detect the candidate edge points of EDLV using ESLV boundaries. The second step is to correct detected boundaries of EDLV using the LV shape. We developed the algorithm of modifying EDLV boundaries defined adaptive modifier. We experimented the method proposed in this paper and compared our proposed method with the manual method in detecting boundaries of EDLV. In the areas within estimated boundaries of EDLV, the percentage of error was about 1.4%. We verified the useflilness and obtained the satisfying results througll the experiments of the proposed method.

Japanese and Turkish are syntactically similar to each other, and there are syntactic structures that become ambiguous in terms of NP's and VP's modified by adjectives and adverbs, respectively. The prosody can play a crucial role in differentiating ambiguous sentences to correctly reflect their intended syntactic structures. In what way do the speakers of Sendai dialect of Japanese and Turkish use prosodic elements to differentiate syntactic ambiguities? Acoustic measurements were made of utterances of ambiguous sentences in Japanese and Turkish to observe prosodic strategies for disambiguation. Materials were sentences of the type ADV-VP1-NP-VP2, ADV-NP1-NP2-VP2, where the ambiguity lies in locative adverbial modification, ADV modifying either VP1 or VP2. For this construction the Japanese and Turkish creates the same ambiguities. In this paper, I look at duration, F0, and pause as observed in their speech and see how each language uses three prosodic elements in disambiguation. The results show that both speakers of Sendai dialect in Japan and those of Ankara dialect in Turky use lengthening of the syllable and/or pause before the boundary.

Mathematical morphology (MM) has been introduced as a powerful tool for studying the geometrical properties of images, MM is a good approach to digital image processing , which is based on the shape feature. The MM operators such as dilation, erosion, closing and opening have been applied successfully to image noise reduction. The MM filters can easily filter the noise when the noise factors are known. However it is very difficult to reduce the noise when images are ambiguous, because the boundary between the noise and object is vague. In this paper, we propose a new method to reduce noise from ambiguous images by using Fuzzy Mathematical Morphology (FMM) operators. Performance evaluation via simulations show that the FMM filters efficiently reduce the image noise. Furthermore, the FMM filters show a good performance compared with the conventional filters.

This experimental study is designed to investigate the acoustic cues produced by English native speakers in order to disambiguate the ambiguous sentences. This study also investigates whether Korean learners of English and English native speakers can perceive the appropriate meanings from the sentences produced with those acoustic cues. In the perception test, English native speakers successfully found out the proper meaning, utilizing the intonational cues, while Korean learners had difficulties in distinguishing the differences in meaning. The break interval was manipulated in order to see whether the pause duration facilitates or interferes with disambiguation. Though phrasing played an important role in disambiguation, the break interval itself did not have influence on it. The result, therefore, suggests that the tonal realization of phrasal accents and boundary tones seem to be more significant than the break interval in the perception of phrasing.
