  • We study, in this paper, on the decorative design of the Treasure-architectural form for the Silla Buddhist reliquary and this research went through the observation on the Buddhist Reliquaries of the Song-Lim-Sa, the Eastern-Western three floor pagodas in the Kam-Eun-Sa, the three floor pagodas in the Bul-Guk-Sa and the reportedly discovered Nam-Won. The Buddhist reliquaries of these 5 Reliquaries, when compared with those of China and Japan in the same period, they worshiped the Buddhist reliquary as a Buddhist God itself and put them as a part of the architectural decoration, being installed in the construction forms. In the form and the composition of the architecture, we can see those having been designed with very detailed and brightly decorated form. The Buddhist reliquaries in the Song-Lim-Sa and Kam-Eun-Sa, the most important ones in this research, were in a royal palace shape having completely the altar part, interior space part, and the ceiling part, which inform us the whole structure of the architecture in details. In particular, for the case of Kam-Eun-Sa, the columns in the shape of bamboo trees, the expression of the gates, the terrace of double parts formed of word-shape Man, and the statue of a general with superhuman ability in the shrine explain us the description of the Gyun-Bo-Tap-Pum of Lotus Sutra. After all these researches, we conclude that the Buddhist reliquaries in form of the Treasure-architecture represented the architectural style of the same period as a form of industrial arts and we can see that they tried to use all of their highly skilled and talented methods to describe the Buddhist Pure Land.

  • This paper prrsents shape matching of two-dimensional object. This shape matching is applied to two-dimensional simple c10sedcurves represented by polygons. A large number of shape matching procedures have proposed baseed on teh view that shape can be represented by a vector of numerical features, and that this representation can be matched using techniques from statical pattern recognition. The varieties of features that have been extracted from shapes and used to represent them are numerous. But all of these feature-based approches suffer from the shortcoming that the descriptor of a segment of a shape do not ordinarily bear any simple relations hip to the description for the entire shape. We solve the segment matching problem of shape matching, defined as the recognition of a piece of a shape as approximate match to a part of large shape, by using relaxation labeling technique.

  • The purpose of this study was to provide basic data necessary for the development of clothing that can improve the satisfaction of body shape of elderly men by examining subjective characteristics and characteristics of perception type of older men's body shape. Using the Q methodology, I investigated and analyzed the process of formation and main characteristics of subjectivity of various types of recognition that elderly men express about their body shape. There were four types of perception of body shape in elderly men: flat hip and bird legs skinny body, back bent and abdominal obese body, thick neck and upper body development body, forward cervical neck and protruding abdomen obese body. The actual body shape of elderly men was classified according to the bust, waist circumference, hip circumference, and body part angle. But recognition body shape of elderly men was classified by visual factors like the abdomen, the angle of the neck, the inclination of the back, the slope of the waist, and the degree of obesity. It is necessary to consider the trend of silver fashion which is increasing in demand. In addition, it is necessary to develop clothing patterns of comfortable fit through ergonomic study on the physical characteristics of older men. Consideration should be given to the design and pattern that can reduce the difference between the ideal body shape and the body shape recognized by older men.

  • We consider a fuzzy controller corresponding to PI controller. This controller is applied to a controlled object which is a first order lag system with dead time. An antecedent part is divided into 3, 5, and 7 parts ( membership function of triangle shape ), and a consequent part into 3, 5, and 7 parts ( membership function of singleton ). In each combination of an antecedent part and a consequent one. We compare control efficiency under the performance criteria such that the overshoot is kept 20% and the ITAE index is minimized.

  • Objective: The objective of this study was to evaluate the osseointegration of narrow-diameter implant with trapezoid-shape and to evaluate the effect of coronal microthreads on trapezoid-shape narrow-diameter implant. Materials and Methods: The experimental narrow-diameter implants were classified into two groups according to absence or presence of coronal microthreads: trapezoid-shape narrow diameter implant (TN group) and trapezoid-shape narrow-diameter implant with microthreads (TNM group). They were installed alternately in bilateral mandible in three dogs. After 8 weeks, the animals were sacrificed. Resonance frequency analysis, removal torque test, and histometric analysis were performed. Results: Statistically higher implant stability quotient (ISQ) values were observed in TNM group than in TN group at the time of implant installation. However, significant ISQ values difference was not observed between groups at 8 weeks. Both groups showed significantly increased ISQ values at 8 weeks, compared to the time of implant installation. There was no significant difference between groups in removal torque test. Bone-implant contact ratio also showed no significant difference between groups in total and coronal part. Conclusion: Within the limitation of this study, it could be concluded that the trapezoid-shape design on narrow-diameter implant showed successful ossointegration, and the microthreads on coronal part did not result in significant bone-implant contact and biomechanical stability at 8 weeks.

  • This study was designed to examine body shape control and its related factors, including BMI(body mass index), desire for weight control, satisfaction with body shape, dissatisfaction with specific parts of body shape, starting period of concern about body shape, as well as experience, method, result, counsel, effort, expense and knowledge of body shape control. The survey was completed by 180 female university students in Gyeongsanbukdo through a self-administered questionnaire during September and October of 2006. The subjects were assigned to one of three groups based on self-estimated figure: 47.8% of the students estimated their figure as 'normal', while 38.3% of the students estimated themselves as 'thin' and 13.9% of the students as 'fat'. The results were as fellows. The mean age of the subjects was $19.45{\pm}1.67$ with a height and weight of $161.15{\pm}4.99cm$ and $52.63{\pm}10.78\;kg$, respectively. Their self-estimated figure was significantly related to BMI, desire for weight control, satisfaction, dissatisfaction with a specific part, and experience, counsel and effort in body shape control. This research suggests that students need to know how to properly control body shape in health and beauty.

  • Information on movement of objects in videos can be used as an important part in categorizing and separating the contents of a scene. This paper is proposing a shape-based movement-matching algorithm to effectively find the movement of an object in video streams. Information on object movement is extracted from the object boundaries from the input video frames becoming expressed in continuous 2D shape information while individual 2D shape information is converted into a lD shape feature using the shape descriptor. Object movement in video can be found as simply as searching for a word in a text without a separate movement segmentation process using the sequence of the shape descriptor listed according to order. The performance comparison results with the MPEG-7 shape variation descriptor showed that the proposed method can effectively express the movement information of the object and can be applied to movement search and analysis applications.

  • Pavilion is an important landscape installation in the traditional landscaping and a representative facility that organizes space. To interpret and succeed the traditional landscape space, researches on the shape and structure of the traditional pavilion are also needed. However, researches on the style and structure of the traditional pavilion are difficult to be found. Accordingly this study aimed to identify the structural characteristics of roof part that occupied the largest portion in determining the shape of pavilion. Our research findings are as follows. As a result of analyzing 15 traditional Single-room square pavilions whose structure could be identified, it was found that the main building elements that distinguished the type of roof part in the Single-room square were crossbeam, ridge pole, and baluster. Depending on the presence of roofing members, pavilion was classified into five types: crossbeam, crossbeam+ridge pole, crossbeam+baluster, ridge pole, and baluster. In addition, as a result of analyzing the load and joint that worked on crossbeam based on the shape classification of roof part, it was found that in the traditional Single-room square pavilion, crossbeam was designed to play a balancing role between pillar and load. This study is significant in that it attempted to make a close interpretation of the shape of roof part in the pavilion and the role and function of building elements in terms of size, ratio, and load.

  • In recent years, design of an optimal blank shape is very important for sheet metal forming process in the automobile industry because the raw material cost rate is significant part in the automobile industry. With the design of an optimal blank shape, the engineer can protect a blank from an excessive holding force to improve the quality and reduce the ratio of material scrap. Therefore design of an optimal blank shape is inevitable in sheet metal forming process. However, if it causes a complicated shape of blank, it may be difficult to do the blank layout optimally. In this study, we developed software of optimal blank layout connected with the software of optimal blank shape design which was created in the past by the present authors. And by using these softwares, we would like to present the method in order to get optimal utilization ratio easily and precisely within short time for the sequence of works from design to blank layout.
