  • Topology optimization method has a great advantage and capability over a conventional shape optimization technique because it optimizes a topology as well as a shape and size of structure. The purpose of the present study, using topology optimization method with an objective function of minimum compliance as a mechanism of bone remodeling, is to examine which shape factors of femur is strongly related with the curvature of femoral shaft. As is expected, the optimized curvature increased definitely with neck angle among the shape factors and showed a similar trend with the measured curvature to neck angle. Therefore, the topology optimization method can be successfully applied in the analysis of bone remodeling phenomenon in the subsequent studies.

  • Objectives : To research origin of the shape of vital gate(命門) in Yixuerunmen makes us understand more exactly what the author, Li Chan(李梴) thought vital gate shaped. Methods : It's shape described in his book was compared with pictures portraying it in Hua Tuo Xuan Men Nei Zhao Tu(華陀玄門內照圖), one of references of his book. Results : He reasonably modified its passing track, while explaining it according to the paintings in Hua Tuo Xuan Men Nei Zhao Tu. Vital gate, as he thought, was not an real organ like the other five viscera, but a cord or a tube similar to blood vessels. He believed its cord had long connections from pericardium to terminal of urethra, which went through pericardium upward, right kidney downward, right around terminal rectum down-frontward, and urethra in parallel outward. Conclusions : He had consistent understandings for vital gate to penetrate several different viewpoints, as based on pictures in Hua Tuo Xuan Men Nei Zhao Tu.

  • The Euclidean distance is sensitive to the absolute offsets of time sequences, so it is not a suitable similarity measure in terms of shape. In this paper. we propose an indexing scheme for efficient matching and retrieval of time sequences based on the minimum distance. The minimum distance can give a better estimation of similarity in shape between two time sequences. Our indexing scheme can match time sequences of similar shapes irrespective of their vortical positions and guarantees no false dismissals

  • In this paper, we propose a method to search the evidence such as a knife found in the crime scene based on GHT from an image database Such objects like knives are simitar in shape. The proposed method utilizes the small shape differences among objects as much as possible to distinguish an object from similar shaped objects. It consists of the GHT based candidate generation and top-down candidate verification. For the fast generation of the candidate 1ist, the GHT operation is performed un the down sampled edge list. The test results show that it can retrieve the correct object even with a pan of object in reasonable time.

  • Ditylenchus acris was isolated from diseased strawberry plants. Frequently, D. acris and Aphelenchoides fragariae occur together in a strawberry plant. Both species appeared very similar in the shape, length, swimming behavior and causing symptoms, and difficult to distinguish them by a stereomicroscope. But they were easily distinguished under a compound microscope especially by their tail shape, median bulb, vulva position, and bursa.

  • Originally, Gyeongcheonsa pagoda was located in Busosan, Jungyeon-ri, Gwangdeok-myeon, Gaepung-gun, Gyeonggi-do,but it has suffered from being taken out to Japan illegally in 1907 and being returned to Korea in 1918. After returned to Korea, Gyeoncheonsa Pagoda had been neglected and restored in 1960. It had been exhibited outside the Gyeingbokgung Palace after restoration, but many problems were raised. It was taken to pieces in 1995 and it is conservation and restoring today. However, the top of pagoda is necessary to be researched about its archetype because the shapes of stupa in 1902 and in 1960(the shape of pagoda after restoration) are all different from its archetype. According to picture datum in 1902, the top of pagoda was a Korean building type on a 10 layered roof stone. On the other hand, when it was restored in 1960, cement suspected as a anda was taken place between Korean building type and a 10 layered roof stone. Therefore, I am going to examine Restoration of Gyeongcheonsa pagoda in this thesis. When we examine historical records of Geongcheonsa and datum of parts, we can know that the pagoda was established in 1348(Goryeo Dynasty) but it is difficult to know the truth of its establishment and demolition of Gyeongcheonsa-temple. Three ways to restore the top of the pagoda of Gyeoncheonsa Pagoda can be c o n s i d e r e d . First, Korean building type made by metals is located on a 10 layered roof stone, which is same to picture datum in 1902. Second, the shape of and a type, which is similar to the shape when it was restored in 1960's. Also it is similar to Lamapagoda type. Third, to restore the top of pagoda of gabled roof type, which is similar to the top of pagoda of Wongaksagi P agoda. However it is necessaray to exmamine functions about circle grooves hollowed out in a 10 layered roof stone in restoration. Also we need to find out the archetype of dragon sculpture through the dragon claws left on an edge of a 10 layered roof stone.

  • Kinematic and kinetic analysis using 3D Motion Capture system are common, yet there is little in the literature that discuss the relationship and coactivity between muscles during the golf swing. The purpose of this study was to describe the relationship between the employed 16 muscles during golf swing. We could observe 3 muscle patterns such as 'Line' shape, 'L' shape, and 'Loop' shape for the golf swing activity. The 'Line' shape indicates that two muscles act almost perfectly in phase, and the 'L' shape represents that two muscles act in a reciprocating manner(When one is active, the other is quiescent and vice versa). And the 'Loop' shape indicates that two muscles act sequently(After one is active, the other act). In these results, we knew the muscle patterns during golf swing is similar to the patterns during gait. And we presented it was possible to show the consistence of golf swing through the frequency analysis of muscle patterns. We believe that the results potentially useful for the golf players and coaches to analyze their performance.

  • Acjurumpo is one of the most representatives daily outfit of Joseon Dynasty is a clothes which has a characteristic of having creases under the armhole and it has a lot of chance to use on modern clothes design. This study wants to provide a information on traditional clothes to the public and modernize traditional clothes by designing modern women clothes by adapting Acjurumpo, one of Joseon Dynasty's men' daily outfit which is not very well-known to publics as a link of traditional clothes modernization. Acjurumpo's characteristic is usually having a knife-shape collar and having two sup and one sup, but outside sup of having two sup was more common. There were tongsu, duri, as a example of shape of sleeve. For Mu the combinations were different from Acjurum starting with a shape of trapezoid, triangle to big Mu on a body of side line. For Gorum there were two pairs of long and short Gorum, two pairs of short Gorum or one pair of short or long Gorum. Slit of po was on both side or back. Acjurumpo which was adapted on modern clothes, it was usually used on Hanbok companies that used traditional shape or similar shape to design children' clothes. This study designed three summer one-piece and two winter jacket for women clothes adapting Acjurumpo. And it was designed by using modern material adapting Acjurumpo's characteristics, changing knife-shape collar, Acjurum, mu and Gorum. This study expects for popularization of many traditional clothes developed by modern design in future.

  • The deformation behavior of the excavated behind ground due to the displacement shape of retention walls is predicted by numerical analysis, which can be performed using the artificial displacement method with elasto-plastic constitutive model. The displacement shape of the behind ground around the retention wall is similar to the displacement shape of the retention wall. However, far from the retention wall, it changes to the displacement shape of cantilever. The deformation (the settlement, the lateral movement) of the excavated behind ground can be decreased by restraining the upper displacement of the retention wall. The displacement shape of the retention wall due to excavation affects on the plastic failure zone and decreasing zone of stability of the excavated behind ground.
