오늘날에는 신체의 시각적 표현이 다양한 범주에서 보여 지고 있고, 컴퓨터 환경이야말로 개별적인 신체의 환경을 뛰어 넘는 커뮤니케이션의 새로운 형태라 말할 수 있다. 사이버 공간에서 몸의 상호 작용의 한 분야로서 게임에서, 캐릭터의 존재와 역할로 커뮤니케이션이 이루어 질 때, 각 캐릭터의 이상적인 신체 표현은 현실을 뛰어 넘는 극적인 아름다움을 표현 한다. 본 논문에서는 미술작품에 나타난 몸의 이미지 표현 방법과 변화과정을 분석하여, 이상적 인간형의 게임캐릭터 창작에 활용할 수 있는 방법을 모색하여 보았다. 캐릭터 제작 기술의 진보는 이미 한계에 이르렀지만, 그리이스시대 이래 현재까지 확립되어 온 신체비 례에 현대적이면서 미래적인 해석을 가미하여, 개성적이고 아름다운 캐릭터 전형을 창조함에 있어서, 이상적 몸의 이미지를 갖춘 캐릭터 창작방법의 바탕을 제시하였다.

The submerged body near the free surface is disturbed by the 1st and 2nd order wave forces, which results in unstable movements when no control is applied. In this paper, the vertical motions of the submerged body are analyzed, and the time-variant nonlinear system for the vertical motions of the submerged body is transformed to the time-invariant linear system in state space. Next, depth controller of the submerged body is designed by using LQR control, one of the modern optimal control technique. Numerical simulation shows that effective depth controls can be achieved by LQR control.

This paper deals with a new method to derive the Generalized Jacobian Matrix of a space robot. In a conventional method to derive the Generalized Jacobian Matrix, generalized coordinates select Joint angles and a space robot body's position and attitude angle. But, in this paper, we select position and attitude angle of the end-effector or the handled floating object as generalized coordinates. Then, we can derive the Generalized Jacobian Matrix of the system which consists of several space robots and a handled floating object. Moreover control methods operated by only one space robot can be easily extended to the cases of cooperation task by several space robots. Computer simulations show that the Generalized Jacobian Matrix derived here is effective.

Purpose : This study sought to evaluate the dimensional stability of the SITT (Silicone Index Tooth Tray) impression system and to determine whether providing space for wash impression material in SITT is a necessary step in obtaining accurate prostheses. Materials and methods : After mounting metal dies with shoulder and chamfer margins arbitrarily, SITT was fabricated using Blu-mousse$^{(R)}$. To test the dimensional stability of the SITT system for margin design, the shoulder margin and chamfer margin were evaluated. Furthermore, to test the effect of space for wash impression material, 0.5mm space in SITT and zero space in SITT were statistically compared. Results : 1. There was no significant difference between the group with shoulder margin and that with chamfer margin. 2. There was no significant difference between the group with 0.5mm space and that with zero space for wash impression material. Conclusions : Considering the limitations of this study, the dimensional stability of the SITT system did not interfere with the margin design. Space for the wash impression material was also unnecessary.

In the history of art and architecture, there are different characteristics in relationship between light and space. Among them, two characteristics seem to be fundamental : The first is that contrast between light and darkness is more articulated. Direct sunlight penetrates into the dark interior space made by heavy masonry structure. This is generally found in the traditional western religious buildings. The second is that light is mixed with darkness and becomes shade. Shade is different from shadow that is usually perceived as the opposite of light. Sunlight is filtered under through the big horizontal roof and rice paper walls in the traditional far-east Asian architecture and becomes weak ambient light. In this shade, there is no strong contrast between light and darkness. This difference is not only originated from the architectural differences, but also originated from the conceptual differences about light, space, and the world in two cultures. This paper tries to study the philosophical, aesthetical backgrounds as well as case examples in art and architecture of two characteristics. Based on the case studies, this paper aims to analyze the main perceptual structure. Finding the relationship between light, space, and human body by making three dimensional models is the crucial analysis method of this research. Although in real life and experiencing the world, these two characteristics are not clearly separated, comparative study based on different cultures gives opportunity to think of diverse perspectives on light and space.

본 논문에서는 대상이 되는 디지털 캐릭터가 기존 애니메이션 파이프라인에서 사용되는 수준의 복잡한 리깅을 가졌더라도, 해당 리깅의 리깅 공간(Rig-space)에 모션을 리타겟팅 할 수 있는 안정적이고 새로운 리타게팅 방법을 활용한다. 이를 위하여 다양하고 복잡한 방식으로 리깅된 서로 다른 캐릭터의 리깅 공간과 캐릭터 관절값 공간(Joint Parameter Space)간의 상관관계를 분석하고, 원본 모션을 최대한 보존하면서 효율적으로 리타게팅을 수행할 수 있는 비선형적 최적화 기법을 제안한다. 이로 인하여 애니메이터는 모션 캡쳐 등으로 얻어진 원본 모션을 수정할 때, 기존의 키프레이밍 작업과 동일한 리깅 파라미터를 사용할 수 있게 되어 직관적이면서도 빠르고 쉽게 모션을 수정할 수 있게 된다. 이 과정에서 애니메이터가 선호하는 작업 방식을 관찰한 후, 해당 과정을 최적화 과정에 반영함으로써 애니메이터가 수정하기에 매우 용이한 형태의 리타겟팅 결과물을 만들어 낼 수 있다.

As for structural system, which constitutes his construction, there are column inside dimension and span which constitutes plane, and as for constructions for section, there are C.H and slab, and as for constructive factors for envelope, there are window and closing panel of outer wall, and as for opening, there are punching window and wave window. With these constructive parts and opening of envelope, his construction composes volume and mass. The relation of structure and modulor which are shown in his later construction can be divided in two cases that modulor is directly and indirectly adapted for rate and measure calculation of the constructive body. As for indirectly adapted case, we can find it form most of his later construction, it is living place in which human beings life is, and it is adapted mainly for small space. In his construction, he tried to tell human scale and sense of musical rhythm through modulor. In other words, he played sense of space and musical scale by adapting regular and repetitive modulor of opening, and in small space for daily life, he made the size of space into the space which human can perceive. And, if we interpret mudulor in modern meaning, it is an establishment of radius of human act. And, we can make organic and harmonic design of space if we use modulor as origin of human centered measurement calculation, and if we adapt space after dividing by use.

In the digital age, as it is ambiguous to distinguish between the original and a replica, the order of reproduction which is more realistic than the reality is becoming a new cultural order. Before the period when digital paradigm dominates, always the reality has been an object to be copied. But, today is an age of Simulacre where code of digital technology dominates. Such a phenomenon is shown in the construction space without exception Gilles Deleuze who was a representative philosopher of the post-structuralism depicted the concept of Simulacre as an instant 'event' passing by without change in an object or substance. As the result of analyzing what kinds of feature for the concept of event is expressed in the digital space, a diagram itself could be a design process, the digital space with correlation was able to be created through the change in the meaning according to the changing image and my body which was the leading part to form primary space. In such a meaning, this study pays attention to Deleuze's 'Event(Simulacre)' concept. At this transitional period when a new concept of digital space is about to take root, the modern philosophers' theories and the discussions about spatial relativity should be continually studied, along with the development of spacial theories for the modem construction.

Many scientifc applications include manipulation of data points tying in a space. We describe a method, based on sector labeling to generate a space-filling curve for partitioning such given data points. Our method is straightforward and flexible, equipping a one-one correspondence between point-values on the curve and data points in space in more efficient than designated methods found in the literature. It is widely believed that the Hilbert curve achieves the desired properties on linear mappings due to the locality between data points. Therefore we focus on the Hilbert curve since, later on, we identify it as the most suitable for our application. We demonstrate on using our method for the data particles of an n-body simulation that based on Barnes-Hut algorithm.
