In the Malaysian license plates, alphabets and numerals which are made by plastic, are adhered to a frame as embossing style and occasionally characters in horizontal, vertical directions are aligned with narrow space. So the extraction of character stroke information can be hard in the vehicle images of low illumination intensity. In this paper, Malaysian license plate recognition algorithm for low illumination intensity image is proposed. DoG filtering based character stroke generation method is introduced to derive exact connected components of strokes in the vehicle image of low illumination intensity. After localization of plate by connected component analysis, characters are segmented and recognized. Algorithm is experimented for the 6,046 vehicle images captured in Kuala Lumpur by IR camera without using any special light during day and night. The experimental results show that recognition accuracy of plates is 96.1%.
Community centers have been public facilities for the welfare and conveniences for the residents since 1999. Currently, the numbers of community centers meet the demands in quantity, but they do not satisfy the quality service needs for the improved life style of residents and the activation of local community. Therefore, the purposes of this research are to find out the current status, types and characters of facilities for the quality improvement of community centers. As the research methods, 'home pages of community centers', 'gujung backseo' were used, and '40 case studies' were completed. Case studies were done by observation and research on the actual conditions. The case works were done between July- September in 2008. Followings are the results of the study; 1. Area measurements of the community centers are being increased since 2000. 2. Complex facility types of community centers are mainly public administrative facilities (community center)+public administrative facilities of mixed type. 3. There are three architectural types of community centers: horizontal type, vertical type, mixed type. 4. There are three classified entrance types for the community centers. 5. There are twelve classified facility types for the community centers. Community centers are usually mixed with diverse facilities, especially welfare facilities and cultural facilities. Proper community center types which contain the functional characters and varieties of facilities should be developed, and these active centers should be used conveniently by residents, thus, further study is required in this regard.

In this paper, we propose a Fuzzy Classifier System(FCS) to find a set of fuzzy rules which can carry out the edge detection of a image. The FCS is based on the fuzzy logic system combined with machine learning. Therefore the antecedent and consequent of a classifier in FCS are the same as those of a fuzzy rule. There are two different approaches, Michigan and Pittsburgh approaches, to acquire appropriate fuzzy rules by evolutionary computation. In this paper, we use the Michigan style in which a single fuzzy if-then rule is coded as an individual. Also the FCS employs the Genetic Algorithms to generate new rules and modify rules when performance of the system needs to be improved. The proposed method is evaluated by applying it to the edge detection of a gray-level image that is a pre-processing step of the computer vision. the differences of average gray-level of the each vertical/horizontal arrays of neighborhood pixels are represented into fuzzy sets, and then the center pixel is decided whether it is edge pixel or not using fuzzy if-then rules. We compare the resulting image with a conventional edge image obtained by the other edge detection method such as Sobel edge detection.
The historical exchanges between the Republic of Korea and Japan have broadly occurred, in terms of both political and cultural aspects, from ancient to modern times. Regarding ancient gardening culture, in particular, Asuka developed gardens with the gardening techniques passed down by the Baekje people. The development of the basic form of a garden pond along with its characteristics, established through such exchanges, is suggested by investigating its components through analysis of data from the gardens of Baekje and Asuka. In terms of the garden pond structure, homogeneity was confirmed between Baekje and Asuka, with a linear rectangular form as the basic design. In addition, the vertical construction technique was used by both ancient kingdoms. In terms of the types of stone used in building the shore of the garden pond, Baekje used diverse types such as natural stone, crushed stone, and cut stone. In contrast, rounded river stone was used by Asuka. Regarding the floor of the garden pond, Baekje used soil, which enabled the planting of lotus flowers. In contrast, Asuka used stones to pave pond floors, which made the growth of plants impossible. In terms of layout, Baekje used ornamental stones for pond landscaping, while Asuka used manmade island and water intake facilities in their pond construction. The effects of Baekje's garden culture on Asuka's garden building can be seen from its influence on the form of the garden pond and shore construction style. In terms of the construction of the garden pond's shore with the same stones and the stone flooring, the garden ponds of the Asuka Kingdom reveal technically unified and refined aspects.

We have increasing number of new ponds planned and designed in traditional styles. However, many of the stoneworks at the edges of those new ponds are not the characteristics of our traditional ponds. This study is aiming at surveying and analysing the building techniques of Korean traditional water edges built with stones, by investigating selected ponds in royal palace gardens. This study was conducted through field investigation and literature reviews. Nine ponds from Gyongbok Palace, Changdeok Palace, and Changgyong Palace, which have many well-preserved ponds of various styles, were surveyed. First of all, the building materials (stones), or the kinds and sizes of stones used for the edges of ponds were surveyed. Secondly, construction methods, or the height and techniques of buildings stone walls were surveyed. Major findings were, first, the edges of most ponds constructed with granite Jangdaeseok, usually 120cm-140cm long, and 30cm-40cm thick. The only exceptions were those ponds which seemed to have been influenced by Japanese style. Second, typical pond ages were up-right vertical walls. Granite jangdaeseoks were piled-up 2 stories or up to six stories. Exceptions were Bandoji Pond and Chundangji Pond which had been constructed during latest period(King 'Ghojong' period). Third, heith of stone walls were between 60cm and 220cm. The depth of ponds were about 150cm or less, and the rest of the edge wall height was freeboard. Though the results of this study was not made by precise investigation and actual measurement, they could be fundamental information and data for the traditional styles of the Chosun dynasty Palace. It is believed that continuous researches on this matter will result in important and fundamental data of the establishment of traditional water edges.

A new classification method and recognition algorithms for printed Korean and Chinese character is studied for Korean text which contains both Korean and Chinese characters. The proposed method utilizes structural features of the vertical and horizontal vowel in Korean character. Korean characters are classified into 6 groups. Vowel and consonant are separated by means of different vowel extraction methods applied to each group. Time consuming thinning process is excluded. A modified crossing distance feature is measured to recognize extracted consonant. For Chinese character, an average of stroke crossing number is calculated on every characters, which allows the characters to be classified into several groups. A recognition process is then followed in terms of the stroke crossing number and the black dot rate of character. Classification between Korean and Chinese character was at the rate of 90.5%, and classification rate of Ming-style 2512 Korean characters was 90.0%. The recognition algorithm was applied on 1278 characters. The recognition rate was 92.2%. The densest class after classification of 4585 Chinese characters was found to contain only 124 characters, only 1/40 of total numbers. The recognition rate was 89.2%.
The Xiaolan channel super large bridge is unique in style and with greatest span in the world with a total length of 7686.57 m. The main bridge with spans arranged as 100m+220m+100m is a combined structure composed of prestressed concrete V-shape rigid frame and concrete-filled steel tubular flexible arch. First of all, the author compiles APDL command flow program by using the unit birth-death technique and establishes simulation calculation model in the whole construction process. The creep characteristics of concrete are also taken into account. The force ratio of the suspender, arch and beam is discussed. The authors conduct studies on the three-plate webs's rule of shear stress distribution, the box girder's longitudinal bending normal stress on every construction stage, meanwhile the distribution law of longitudinal bending normal stress and transverse bending normal stress of completed bridge's box girder. Results show that, as a new combined bridge, it is featured by: Girder and arch resist forces together; Moment effects of the structure are mainly presented as compressed arch and tensioned girder; The bridge type brings the girder and arch on resisting forces into full play; Great in vertical stiffness and slender in appearance.

This paper proposes a variance recovery method for character strokes that can be missed in applying the previously proposed color variance approach in text detection of natural scene images. The previous method has a shortcoming of missing the color variance due to the fixed length of horizontal and vertical windows of variance detection when the character strokes are thick or long. Thus, this paper proposes a variance recovery method by using geometric information of bounding boxes of connected components and heuristic knowledge. We have tested the proposed method using various kinds of document-style and natural scene images such as billboards, signboards, etc captured by digital cameras and mobile-phone cameras. And we showed the improved text detection accuracy even in the images of containing large characters.

This study analyzed the style, dimensions, fabric patterns, colors, and fabrics of a traditional Chinese women's dress from the Zhou Dynasty, and reconstructed it in the form of a virtual garment using 3D CLO. Based on ancient flat image data and three-dimensional portrait data, who wore them, how they were worn, and how they were coordinated was analyzed. In order to analyze the size and pattern of the straight Ju Chines dress, data from the excavation report and the tomb owner's anthropometric measurements were combined to infer the wearing condition and organize the sculptural features. Dimensional analysis was carried out using a well-preserved small-scale woven cotton cloth as a restoration model, and the horizontal and vertical dimensions were reasonably estimated using the shape proportioning method. The analysis of the colors and patterns of the fabrics was based on the colors and patterns of the fabrics excavated from Masan Tomb No. 1 during the Eastern Zhou, Qin, and Han periods. Finally, a virtual model was created using data from the excavation report and the age and height information of the owner of the excavated robe, and the pose and size of the virtual model were determined using 3D CLO. Based on the previous research data, the garment was virtually sewn and simulated. The shape, pressure, and strain of the garment in different postures was also compared. Through the research direction of pattern and 3D restoration, this research maximizes the restoration of Chinese traditional women's dress and presents it in a more intuitive, comprehensive, and vivid way.
Interior design has diverse functions and roles according to recent changes in life and cultural style. As the meaning of space varies, the furniture as another element of the space should also be planned and included in the beginning of the project to accomplish its functional role on the finished space and not only be placed. The relationship between Interior space and furniture should be studied and understood at the same realm because they have a complementary relationship. The final destination of design, which is very challenging to accommodate people, the designer needs to approach to the interior space and furniture in a cognitive view. The study of Semiotics views in a knowledgeable and epistemological way every element as a sign and by the relationship of their characters it makes to understand the structure of the signs. Charles Sanders Peirce, a leader of Semiotics in USA, classified the structure of Sign into Representamen, Object and Interpretant to complete the theory which could systematically describe physical characteristic and function of the Sign and its significance in practical use. Peirce stated that all nine types of Sign would be generated if each structure of Sign in combined with three categories of Sign such as Firstness, Secondness, and Thirdness. In this study, based on Peirce's nine types of Sign, the interrelationship between space and furniture in interior design was investigated with examples in Living Space, Office Space, and Commercial Space, respectively. In the category of Representamen, which can be classified into Qualisign, Sinsign, and Legisign, it is a feature of Living Space to be expressed in harmonized and stabilized ways. In Office Space vertical/horizontal elements and open expression are differently showed depending on fields. And splendid and interesting expressions are showed in Commercial Space. In the category of Object, which can be classified into Icon, Index, and Symbol, each function of Sign has distinctly been showed as Symbol in Living Space, Index in Office Space, and Icon in Commercial Space, respectively. In the category of Interpretant, which can be classified into Rheme, Dicisign, and Argument, it was found that space image of Living Space is transferred to human being, Office Space regulates human bing, and Commercial Space binds human being with the space. In conclusion the function of the interior space and the furniture could be explained in another way with re-interpretation of interrelationship among interior space elements in the concept of Semiotics. It is expected that interpretation with Semiotics in interior design will grow to new theory of design.
