  • This research was designed to investigate biomechanical aspects of the evolution based on the hypothesis of dynamic cooperative interactions between the locomotion pattern and the body shape in the evolution of human bipedal walking The musculoskeletal model used in the computer simulation consisted of 12 rigid segments and 26 muscles. The nervous system was represented by 18 rhythmic pattern generators. The genetic algorithm was employed based on the natural selection theory to represent the evolutionary mechanism. Evolutionary strategy was assumed to minimize the cost function that is weighted sum of the energy consumption, the muscular fatigue and the load on the skeletal system. The simulation results showed that repeated manipulations of the genetic algorithm resulted in the change of body shape and locomotion pattern from those of chimpanzee to those of human. It was suggested that improving locomotive efficiency and the load on the musculoskeletal system are feasible factors driving the evolution of the human body shape and the bipedal locomotion pattern. The hypothetical evolution method employed in this study can be a new powerful tool for investigation of the evolution process.

  • In this paper, we present a new shape descriptor, which is named Poisson equation-Fourier-Mellin moment Descriptor. We solve the Poisson equation in the shape area, and use the solution to get feature function, which are then integrated using Fourier-Mellin moment to represent the shape. This method develops the Poisson equation-geometric moment Descriptor proposed by Lena Gorelick, and keeps both advantages of Poisson equation-geometric moment and Fourier-Mellin moment. It is proved better than Poisson equation-geometric moment Descriptor in shape recognition and classification experiments.

  • This thesis attempts to contribute to analyze the methods of pattern grading which is in common fashion in America and Japan and to make the foundation for the basic technique of pattern grading fitting to Korean body shape. There are two types in pattern grading. The results are as follows: 1) The pattern grading according to body shape contains A, B, C, D, F, and G. A is suitable for the bulging part of a body and F is the most suitable for the general part of a body. 2) The pattern grading not depending on body shape has no relation to the quantity of grading in the size of a body but includes silhouettes or design details. The standards of its methods are as follows: a) by the part of body b) by the balance of whole pattern c) by adjusting to the mutual balance of besign details.

  • The purpose of this study is to find the profitable clothes design of middle-aged men by examining visual effects in physical design. The methode of study is experimentation. The sample of this study is people who live in Kwangiu, Korea and 20-50 age's 719. The difference of physical design effect by arrangement, pattern and the shape of body. There are partly resemblance difference in physical design visual effect by the shape of body and clothes design(arrangement and pattern)In weak type, single suit with striped pattern and double suit with check pattern make the upper body look short. Otherwise, double suit with striped pattern have man look tall. In standard type, single arrangement suit with striped pattern make the lower half of body long, so make man look tall. And double arrangement suit with striped pattern have man look tall. The suit without pattern have one's shoulder look wide. In pyknic type, striped pattern make the lower half of one's body look long. But single arrangement with striped pattern have the upper body look big. sing1e suit with striped pattern make lower half of body look long and check pattern make it look short. Totally, arrangement, and pattern are very important clothes due to give an effect on whole visual effect man's suit. Also, these dues were felt differently by each types of body. So, it is confirmed that the type of body is important fluent to make people perceive.

  • Recently, Basic patterns with excellent body fitness and automation availability are required to be developed in order to automate the patterns of women's clothes. In this study, this reference points, reference lines and segments were fixed onto 3D scan data for the lower body the women in their twenties, they were directly spread out to be 2D flat pattern to facilitate development into the design of slacks adhered closely to the human body such as special and highly-functional clothes, and then slacks 2D pattern was developed for the purpose of seeking scientific approach to the development into basic form slacks and 3d emotional pattern. For conversion of 3D pattern into 2D flat pattern, reference points and segments were created by using Rapid Form of 3D shape analysis software, and triangle mesh of the body surface of the created shape was developed with Auto CAD 2005. The correspondence between slacks and human body was examined by the fixation of major reference lines. Specially, the wearing characteristics of slacks were considered by the fixation of side lines in consideration of posture. As a result of using the way of development to constantly maintain the length while 3D triangle mesh is converted into 2D flat mesh, the shape was shown to be excellently reproduced, and the area of flat pattern was increased compared to the shape of parting plane. Also, the sunk-in curve like the brief line of front crotch length needed a cutting line when it was closely adhered, when mesh was overlapped, and the pattern area was smaller compared to the actual shape.

  • The aim of this study is to figure out the preference features on design components of shop facade on the basis of the questionnaire survey on short-term memory and sensory memory of human right after an image experiment. As for a preceding research, this study examined the design features of facade into tangible elements and intangible elements, and also classified them into physical, aesthetical, marketing and symbolic components in detail. And, it extracted 5 representative elements in preceding studies including shape, material, pattern, color and sign, which is the standard of a questionnaire survey and preference analysis. The subjects of the experiment were 30 men and women who were over 20 years old majoring interior design. They were exposed to 20 images with 10 seconds respectively through a video, and were asked to respond the questionnaire promptly. The findings of preference analysis of design components of facade including shape, material, pattern, color and sign are as follows. Firstly, shape was the most interesting and attracting component, and designs applied with shape of objects such as 'web', 'drawer', 'wheel' and 'button' obtained high preference. Secondly, as for material, block, steel, exposed concrete board attracted higher preference as memorable materials than other materials. Material was affected by shape, pattern and color. Thirdly, pattern was the most lasting element. Designed pattern had higher preference than simple pattern. Fourthly, as for color, red and green with strong stimulation and attention attained priority having long lasting memory. Fifthly, when visiting a shop, sign out of 5 elements of shape, material, pattern, color and sign drew attention the most. As for the preference of location of sign, 'center top' was the most noticeable. The findings of this study could be utilized for facade design, and also could be used for commercialization considering highly preferred components, and top preference aspects of such elements. advised that to give an impression to customers is important to make a successful design for sales marketing, which, in turn, would lead customers to revisit the shop.

  • In the apparel industry, the technology has been advanced rapidly. The use of 3D scanning systems fur the capture and measurement of human body is becoming common place. Three dimensional digital image can be used for design, inspection, reproduction of physical objects. The purpose of this study is to develop a method that drafts men's basic bodice pattern from scanned 3D body surface shape data. In order to pursue this purpose the researchers developed pattern drafting algorithm. The 3D scanner used in this study was Cyberware Whole Body Scanner WB-4. The bodice pattern drafting algorithm from 3D body surface shape data developed in this study is as follows. First, convert geometric 3D body surface data to 3D polygonal mesh data. Second, develop algorithm to lay out 3D polygonal patches onto a plane using Auto Lisp program. The polygon meshes are coplanar, and the individual mesh is continuously in contact with next one The bodice front surface shape data in polygonal patches form was lined up in bust and waist levels. The back bodice was drafted by lining up the polygonal mesh in scapula, chest, and waist levels. in the drafts, gaps between polygons were formed into the darts.

  • Countries have different brassiere patterns, and this study produced and compared 3/4 brassiere patterns from different countries to determine the difference in patterns, and to investigate the stress distribution and shape of cross section while wearing brassieres using 3D virtual fitting system. Despite the growing interest in underwear, there is a lack of related books and research on brassiere patterns, which causes the difference in sizes and pattern drafting methods by countries. Thus, research on this is needed. 3D virtual fitting system has been introduced to compare patterns, thereby improving visible effects and reducing the loss in cost caused by underwear pattern fitting test. According to the result of pattern analysis, The Secoli type exhibited the least breast cover rate (14.9 cm), while the largest cover rate was shown in Christina and ESMOD types (17.7 cm). It is believed that the difference in pattern drafting causes the difference in the total length of a brassiere. Furthermore, the Secoli, Moda Burgo, and ESMOD brassieres drafted from basic bodice pattern were found to be longer than the Christina and Han Sunmi brassieres attained from direct pattern drafting. Moreover, the darts' volume of upper and lower cups in Christina and Han Sunmi types was similar in shape. The shapes of cradle drafted from basic bodice pattern were a straight line, while those from direct drafting formed a curved shape. In fitting multiple cross sections, the Secoli, Moda Burgo, and ESMOD brassieres had gaps between the brassieres and the body. Among these, the largest number of gaps was observed in the ESMOD type pattern. This study aimed at performing comparative analysis of various brassieres' pattern drafting types as a basic research for developing a brassiere pattern drafting type.
