In this study, we classified adjectives to represent the image of clothing materials as the fundamental process for evaluation of the images on various fabrics and reviewed hierarchy and evaluation dimensions regarding the image of clothing materials. The adjectives to express the image of clothing materials were extracted from Fashion Magazine and Fashion Trend Book The similarity among adjectives was measured by pair-wise comparison without showing fabrics. From the result of the cluster analysis, 87 adjectives were finally extracted through the integrated processing of the adjectives with similar meaning and a close distance. Through the cluster analysis, the hierarchy of the clothing material images was examined. The clothing material images were classified into 12 primary sub-clusters such as ‘feminine', ‘warm', ‘neat', ‘classical', ‘pastoral.' ‘casual', ‘modern'. ‘ambiguous', ‘primitive', masculine', ‘abundant', and ‘arranged'. The dimensions evaluating the clothing material images were also developed using the multi-dimensional scaling method. A 4-dimensions and 8-axes system was established, which is composed of ‘masculine-feminine', ‘new-old', ‘casual-classical', and ‘ambiguous-arranged' images.

We propose a variational segmentation model based on statistical information of intensities in an image. The model consists of both a local region-based energy and a global region-based energy in order to handle misclassification which happens in a typical statistical variational model with an assumption that an image is a mixture of two Gaussian distributions. We find local ambiguous regions where misclassification might happen due to a small difference between two Gaussian distributions. Based on statistical information restricted to the local ambiguous regions, we design a local region-based energy in order to reduce the misclassification. We suggest an algorithm to avoid the difficulty of the Euler-Lagrange equations of the proposed variational model.

To be a good architecture, resident' needs should be defined as possible as definitely. A Multi-family housing is not easy to define of resident' needs, because the user is ambiguous and the needs is multi aspects. Byker housing project have a good approach to define ambiguous and many aspects of residence' need. In this view points, Byker redvelopment project show the process of resident' participation as a new customers, and design process architect with people, in spite of the early 1970s' project in terms of the user participations. This approach of residence participation is a good lesson how to communicate with recidence, how to identify the need, and its design is satisfied in the residence. And its project are discussed with residence how to manage of rehabilitation.

This study examined whether children's peer representations are associated with peer acceptance and whether attributions and goals are related to representations about behavioral responses in ambiguous provocation and conflict situations. The subjects were 119 5th-grade children responded to 4 hypothetical situations. Results indicated that children's positive representations about peer conduct in ambiguous provocations were related to their higher level of peer acceptance, and positive representations about a friend in conflict situations were associated with their perceived positive qualities of friendship. Children's positive attribution and relational goal orientation were associated with relational behavioral responses. Gender differences were found for some goals and behavioral responses, with girls displaying a more relational goal and behavioral response orientation than boys.

Automatic language translation has greatly advanced due to the increased user needs and Information retrieval in WWW. This paper utilizes the integrated knowledge bases of noun and verb networks for automatic translation of ambiguous words in the Korean sentences, through the selectional restriction relation in the sentences. And this paper presents the method to verify validity of Korean noun semantic networks that are used for the construction of the selectional restriction relation by applying the networks to the syntactic and semantic properties Integration of Korean Noun Networks into the SENKOV system will provide the accurate and efficient knowledge bases for the semantic analysis of Korean NLP.

This paper describes an audio source separation that is based on nonnegative matrix factorization (NMF) and expectation maximization (EM). For stable and highperformance separation, an effective auxiliary source separation that extracts source residuals and reprojects them onto proper sources is proposed by taking into account an ambiguous region among sources and a source's refinement. Specifically, an additional NMF (model) is designed for the ambiguous region - whose elements are not easily represented by any existing or predefined NMFs of the sources. The residual signal can be extracted by inserting the aforementioned model into the NMF-EM-based audio separation. Then, it is refined by the weighted parameters of the separation and reprojected onto the separated sources. Experimental results demonstrate that the proposed scheme (outlined above) is more stable and outperforms existing algorithms by, on average, 4.4 dB in terms of the source distortion ratio.

This paper presents a new image segmentation method using fuzzy measures which reflect the local property of an image as well as the global property of an image An image is globally segmented into the crisp region and the ambiguous region in terms of the Index of fuzziness measured over all pixels of an image. The ambiguous region is luther partitioned into background and object in terms of the index of fuzziness computed over the set of neighboring pixels reflecting the local property most. From the experimental results, this method shows the effective ambiguity handling capability in segmenting an image.

Future GNSS signal using BOC modulation brings the advantages of positioning accuracy and multipath rejection. However, the BOC signal has an ambiguous autocorrelation function that complicates the process of acquisition. Three techniques that solve the ambiguous problem are BPSK-like, Sub Carrier Phase Cancellation, and Bump Jumping. In this paper, these methods are implemented by means of a DSP/FPGA board. Moreover, an experiment is conducted to examine and compare the performance of these techniques.

'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.

CMP (Chemical-Mechanical Polishing) is a process in which both chemical and mechanical mechanisms act simultaneously to produce the planarized wafer. CMP process is an extensive usage and continuing high growth rates in the semiconductor industry. The understanding of the process, however, is much slower. The nature of material removal from the wafer is still undefined and ambiguous. Material removal rate according to the slurry flow rate is also undefined and ambiguous. Thus, in this study, the basic mechanism of material removal rate as slurry flow rate is defined in terms of energy supply and energy loss.
