2-D shape descriptors, which are vectors representing characteristics of shapes, enable comparison and classification of shapes and are mainly applied to image and 3-D model retrieval. Existing descriptors have limitations that they only describe shapes of single closed contours or lack in precision, making it difficult to be applied to shapes with multiple contours. Therefore, in this paper, we propose a new shape descriptor called Multi-Curvature-Scale Space that can be applied to shapes with multiple contours. Specifically, we represent the topology of the sub-contours in the multi-contour along with Curvature-Scale Space descriptors to represent the shapes of each sub-contours. Also, by allowing the weight of each component to be controlled when computing the distance between descriptors the weight, we deal with ambiguities in measuring similarity between shapes. Results of various experiments that prove the effectiveness of proposed descriptor are presented.

For the purpose of this study is the re-searcher investigated the concept and background of kitsch and the character of Kitsch in the paintings with focus on the Surrealism and Pop Art. In this study it was focused that how the shapes and materials was expressed in the modern fashion. Surrealism in paintings is lead thoughts and art movement to humanism of be-having man and pursuit of mental sub-stance of human beings expressing un-conscious word and transforming image in new way by the methods Automatism and Depaysements. Pop Art in paintings is used to objects common and cheap in the popular con-sumer's society. That is to say Pop Art sublimated con-sumptional culture of mass as art. And this phenomenon is appeared in the modern fashion which have influencedon the shapes and materials in design. Kitsch's character was researched in terms of shapes materials in the modern fashion with focus on the Surrealism and Pop Art and their aspect are summarized as follows: 1. In he aspect of shapes it appears that the shapes in the modern fashion is that of play through the method distor-tion or modification of dress. It was un-derstood that the cause of the dreaming and fantasy in the childhood. In the aspect of materials it apepears that the materials in the modern fashion is that of exagerated-decoration through using of object which is various asses-sories flower doll etc. 2. In the aspect of shapes it appears that the shapes in the modern fashion is that of disharmoney disorder and unsuit-ableness. The major cause of that is be-cause of Antistandard fashion I the aspect of materials it appears that the materials in the modern fashion is that of sarcasm pleasantness. It was reviwed that the major cause of the wit or humor comes from the image of the masses makes use of such as plastic fun-ny picture can coin etc.

A supersonic nozzle specially is one of the important part in a supersonic turbine usually adapted the impulse type, because the flow acceleration in the turbine theoretically is done only in the nozzle. The present study deals with numerical flow analysis to investigate the effect of nozzle shapes on the performance characteristics of a partial admission supersonic turbine. The flow analysis was performed for four different nozzle shapes. The shapes of the nozzles are circular, square, straight rectangular and bent rectangular nozzles. The results of the flow analysis showed that the aerodynamic loss of turbine is highly affected by the nozzle shapes, and the partial admission loss is also highly depended on nozzle shapes. Specially, bent rectangular nozzle had the best performance among the nozzle shapes

Menswear body types are often labeled on garments (to indicate how the garments are designed to fit) with indicators of a size category such as regular, portly, and stout, athletic, or big and tall. A drop (relationships between the chest and waist girths) is related to the fit of a tailored suit. However, current standards are not designed for various drops or body types. There is not enough information of categorizing men's body shapes for the apparel sizing systems. In this article, a set of men's data from SizeUSA sizing survey was analyzed to investigate men's body shapes and drops. Factor analysis and a cluster analysis method were used to categorize men's body shapes. In the results, twenty-five variables were selected through the factor analysis and found four factors: girth factor, height factor, torso girth factor, and slope degree factor. According to the factor and cluster analysis, various body shapes were found: Slim Shape (SS - tall ectomorphy), Heavy Shape (HS - athletic, big & tall, endomorphy and mesomorphy), Slant Inverted Triangle Shape (SITS - regular, slight ectomorphy and slight mesomorphy weight range from normal to slightly overweight), Short Round Top Shape (SRTS - portly and stout, endomorphy). Body shapes were related to fitting categories. SS and HS were related to big & tall fitting category. SITS was related to regular. SRTS was related to portly and stout. Shape 1 (31%) and Shape 2 (26%) were related to current big & tall category. Shape 3 (34%) were related to regular. Shape 4 (9%) were in portly and stout category. ASTM D 6240 standard was the only available standard that presented a regular fitting category. Various drops were found within a same chest size group; however, this study revealed great variances of drops by body shape.

In modal analysis, the mode shape reflects the vibration characteristics of the structure, and thus it is widely performed for finite element model updating and structural health monitoring. Generally, the acceleration-based mode shape is suitable to express the characteristics of structures for the translational vibration; however, it is difficult to represent the rotational mode at boundary conditions. A tilt sensor and gyroscope capable of measuring rotational mode are used to analyze the overall behavior of the structure, but extracting its mode shape is the major challenge under the small vibration always. Herein, we conducted a feasibility study on a multi-mode shape estimating approach utilizing a single physical quantity signal. The basic concept of the proposed method is to receive multi-metric dynamic responses from two sensors and obtain mode shapes through bridge loading test with relatively large deformation. In addition, the linear transformation matrix for estimating two mode shapes is derived, and the mode shape based on the gyro sensor data is obtained by acceleration response using ambient vibration. Because the structure's behavior with respect to translational and rotational mode can be confirmed, the proposed method can obtain the total response of the structure considering boundary conditions. To verify the feasibility of the proposed method, we pre-measured dynamic data acquired from five accelerometers and five gyro sensors in a lab-scale test considering bridge structures, and obtained a linear transformation matrix for estimating the multi-mode shapes. In addition, the mode shapes for two physical quantities could be extracted by using only the acceleration data. Finally, the mode shapes estimated by the proposed method were compared with the mode shapes obtained from the two sensors. This study confirmed the applicability of the multi-mode shape estimation approach for accurate damage assessment using multi-dimensional mode shapes of bridge structures, and can be used to evaluate the behavior of structures under ambient vibration.

This study aims to study mouth shapes suitable to the shapes of Korean consonants and vowels for Korean animations by analyzing the process of English-speaking animation lip-sync based on pre-recording in the United States. A research was conducted to help character animators understand the concept of Korean lip-sync which is done after recording and to introduce minimum, basic mouth shapes required for Korean expressions which can be applied to various characters. In the introduction, this study mentioned the necessity of Korean lip-sync in local animations and introduced the research methods of Korean lip-sync data based on English lip-sync data by laking an American production as an example. In the main subject, this study demonstrated the characteristics and roles of 8 basic mouth shapes required for English pronunciation expressions, left out mouth shapes that are required for English expressions but not for Korean expressions, and in contrast, added mouth shapes required for Korean expressions but not for English expressions. Based on these results, this study made a diagram for the mouth shapes of Korean expressions by laking various examples and made a research on how mouth shapes vary when they are used as consonants, vowels and batchim. In audition, the case study proposed a method to transfer lines to the exposure sheet and a method to arrange mouth shapes according to lip-sync for practical animation production. However, lines from a Korean movie were inevitably used as an example because there has not been any precedents in Korea about animation production with systematic Korean lip-sync data.

Custom-tailored products are meant by the products having various sizes and shapes to meet the customer's different tastes or needs. Thus fabrication of custom-tailored products inherently involves inefficiency. To minimize this inefficiency, a new paradigm is proposed in this work. In this paradigm, different parts are grouped together according to their sizes and shapes. Then, representative shape of each group is derived and it will be used as the work-piece from which the parts in the group are machined. Once a new product is ordered, the optimal work-piece is selected through making similarity comparisons of new product and each representative shape. Then an effective NC tool-path is generated to machine only the different portions between the work-piece and the ordered product. The efficient machining conditions are also derived from this shape difference. By machining only the different portions between the work-piece and the ordered product, it saves time. Similarity comparison starts with the determination of the closest pose between two shapes in consideration. The closest pose is derived by comparing the ray distances while one shape is virtually rotated with respect to the other. Shape similarity value and overall similarity value calculated from ray distances are used for grouping. A prototype system based on the proposed methodology has been implemented and applied to the grouping and machining of the shoe lasts of various shapes and sizes.

The purpose of this study is to measure middle aged men's bodies around the ages of thirty-five through filly-five, whose age-group undergoes drastic changes on their body shapes. Further, body shapes are grouped based on the measurements, and pattern making methods are presented in order to effectively make up for the undesirable body features of middle-aged men. In order to develop patterns fit for middle aged men's body shapes, the regression which reflects physical characteristics was applied for the experimental shirts pattern, instead of comparative patterns which applies the same equation. For the two body types classified above(Bend-forward Type and Lean-back Type), correlation among the factors necessary for pattern design was considered and the regression was formularized accordingly. To validate the regression, the same amount of ease as in the comparative patterns was applied to the chest girth, and reasonable ease to the armhole depth and neck girth. In this way, experimental shirts patterns fit for the body types were developed. After the modification through the wearing test, the experimental shirts pattern was completed as herein.

Survey was conducted on 201 female college students who in at the university to analyze perceptions and satisfaction levels about their body shapes. Results revealed that the Chinese female students recognized that they had broader shoulder angles, bigger breasts and longer calves and legs than Korean female students whereas the Korean female students had larger hip and thigh circumference than Chinese female students. It was found that the Chinese female students had preference for drooping shoulders while the Korean students perceived themselves as thinner and have longer arms, fingers, waist measurement, torso thickness, calves, feet and legs are ideal body shapes. The results of this study show that body weight, height and chest size have a lot of influence on it and the Korean female students were less satisfied their body shape compared with the Chinese female college students. The correlation analysis indicated that body shapes were an important indicator of satisfaction and the thinner the body shape, chest, thigh, waist, finger, arms, the greater the satisfactions.
