애니메이션 캐릭터는 그 표정이나 동작을 강화하기 위해 탄성 원칙이 적용되어 질 수 있다. 이 원칙을 애니메이션에서는 스쿼시와 스트레치라고 부른다. 이 원칙의 적용은 캐릭터에게 무게와 부피의 허상을 제공하며, 애니메이션 동작의 뻣뻣함과 딱딱함을 벗어나, 부드럽고 유연한 동작이 되게 하는 것을 가능하게 한다. 애니메이션에서 인물이나 사물의 동작표현을 실제 세계와 같이 표현하게 되면, 부자연스럽게 보인다. 스쿼시와 스트레치가 없는 어떤 동작이든 딱딱하고 흥미가 없고, 살아있지 않은 것으로 보일 것이다. 이것은 질량, 부피, 중력의 기본 법칙과 함께, 모든 사물의 움직임, 캐릭터의 동작, 대사, 얼굴표정 등에 모두 적용될 수 있다. 무거운 캐릭터는 가벼운 캐릭터 보다 더욱 스쿼시와 스트레치가 강조된다. 이 원칙 이 없이는 어느 동작도 잘 표현되지 않을 것이다. 좋은 애니메이션 움직임이 되려면, 이것은 2D 애니메이션에서 만이 아니라, 모든 형식의 애니메이션에서 널리 적용되어야 한다.

We investigated space establishment and land use of children's parks by studying movement of users in and out of the parks with a questionnaire survey, video and analysis, and then analyzed the characteristics of how the facilities and the space of the parte are used. The results are as follows. First, when considering the character of the facilities of children's parks, entertainment facilities should receive priority followed by those for relaxation and those for convenience. When considering the position of facilities in the parks, because activity spaces may have similar functions to multi-purpose paved spaces, common use of these two spaces should be considered. Entrances and lines of movement should be kept in mind. Second, when considering the surrounding land uses, in case a play facility at a large-sized complex or an elementary school is adjacent, the exercise facilities may be more important, followed by play and rest facilities. In case there is a broad path around the parte, the way in which movement occurs into the central axis should be considered so that the other side of the broad way is not included in the children's play space. Third, proper control of roads adjacent to the parse is needed to protect children from danger.

본 논문은 클라이언트-서버 방식을 사용하는 대규모 1인칭 온라인 슈터 게임(MMOFPS)에서의 네트워크 부하를 줄이기 위한 효율적인 적응적 패킷전송 주기 방법을 제안한다. 플레이어 움직임에 있어서 빠르고 지속적인 변화와 정적이고 선형적인 상태가 다양하게 공존하는 FPS 게임의 특성상 변화의 정도에 따라 서버로의 패킷 전송량을 절약할 수 있는 지점들이 존재하는데, 이를 위해 본 논문에서는 클라이언트가 매 패킷을 전송할 때마다 플레이어의 위치 및 움직임 변수들의 변화량을 측정하여 이를 기반으로 다음번 패킷이 전송되어야 할 시간 간격을 계산한다. 서버 측에서는 받은 패킷의 정보들을 사용하여 다음 패킷이 도착할 때까지의 공백을 메우기 위해 위치 예측을 수행하여 모든 클라이언트에게 브로드캐스팅을 하게 된다. 긴 패킷 전송 간격으로 인한 예측 오차를 줄이기 위하여 전송 간격 최대한계치와 이중 패킷전송 등의 추가적 작업을 수행한다. 결과의 효율성을 보이기 위해 테스트 게임 환경을 구축하여 기존의 고정된 패킷전송 주기 시스템과의 비교분석을 수행하였다.

The performance-art costume is a tool for expression that can dynamically display the intention of a production. The purpose of this study is to examine the whole costume for performance arts targeting musical works, to which were added such elements as music, dance, and drama, among performance arts in several genres. This study aims to consider how the symbol contained in the costume was intended to be expressed by inferring a change in performance costume and character as the stage costume. Accordingly, the following research problems were established in this study. First, Which role does the costume play in performance art? Second, into which types can the performance-art costume be classified depending on the kind of performance art? Third, what is the expressive method for the performance-art costume? To examine the types of performance-art costume, the acting costume, the singing costume, the dancing costume and the rhythmic performance costume were considered. As a result, the performance costume can be seen to have been designed through the effect of a change in color by lighting, through the differentiation of character caused by excessive decoration, through the differentiation in material for free movement, and through symbolic expression.

We describe the development of an interactive aerobic training system using vision-based motion capture and multimedia technology. Unlike the traditional one-way aerobic training on TV, the proposed system allows the virtual trainer to observe and interact with the user in real-time. The system is composed of a web camera connected to a PC watching the user moves. First, the animated character on the screen makes a move, and then instructs the user to follow its movement. The system applies a robust statistical background subtraction method to extract a silhouette of the moving user from the captured video. Subsequently, principal body parts of the extracted silhouette are located using model-based approach. The motion of these body parts is then analyzed and compared with the motion of the animated character. The system provides audio feedback to the user according to the result of the motion comparison. All the animation and video processing run in real-time on a PC-based system with consumer-type camera. This proposed system is a good example of applying vision algorithms and multimedia technology for intelligent interactive home entertainment systems.

본 논문은 동작 포착 장비를 통해 각각 따로 포착된 얼굴과 동작 데이터의 자동 동기화 기술에 대해 다룬다. 광학식 동작 포착 기기를 사용할 때 얼굴 표정과 동작의 포착은 별도로 이루어지는 경우가 많으며, 이 경우 두 데이터 간의 동기화 수행하여야 자연스러운 애니메이션을 만들 수 있다. 본 연구에서는 두 데이터 간의 공통 부분인 목 및 얼굴의 전체적인 움직임 데이터를 기준으로 비선형 시간 변형을 통해 동기화를 수행하는 기법을 제안한다. 연구 결과를 간단한 실험 시나리오에 적용하여 기술의 효과성 여부를 검증하였다.

When one speaks of space in architecture, one immediately thinks of an entity that is an enclosed space. For most people , space is therefore equated with interior space. And in most discussions of architectural space the character of the outside and that of the inside have been strictly differentiated. But architectural space must be construed as a total , integral space. In this way , architectural space can articulate naturality. For example, by reasserting the eloquence of architecture and by graphically characterizing the different parts of the building. Ungers has moved far away from the traditional ideas of a modern movement that preached the homogeneity of all parts. so promoting uniformity and an expressionless monotony. From this perspective comes the purpose of this study which is to present :1. the character and meaning of the boundary that differentiates the outside from the inside of the architecture. 2. the types of the organization of the interior-space and the differences between those types. 3. the new concept of the interior -space through the analysis of the concept "Haus im Haus" that over-comes the polarity of the outside and the inside of ar-chitecture. This result comes from the idea that harmony is a-chieved not by resolving this polarity into one or the other extreme, but by allowing coexistence of both as-pects.

In this paper we describe a motion tracking algorithm for 3D human animation using stereo vision system. This allows us to extract the motion data of the end effectors of human body by following the movement through segmentation process in HIS or RGB color model, and then blob analysis is used to detect robust shape. When two hands or two foots are crossed at any position and become disjointed, an adaptive algorithm is presented to recognize whether it is left or right one. And the real motion is the 3-D coordinate motion. A mono image data is a data of 2D coordinate. This data doesn't acquire distance from a camera. By stereo vision like human vision, we can acquire a data of 3D motion such as left, right motion from bottom and distance of objects from camera. This requests a depth value including x axis and y axis coordinate in mono image for transforming 3D coordinate. This depth value(z axis) is calculated by disparity of stereo vision by using only end-effectors of images. The position of the inner joints is calculated and 3D character can be visualized using inverse kinematics.

In this paper, we have proposed license plate recognition system for multi-national vehicle license plate using geometric features along with hybrid and seven segment pattern vectors. In the proposed system, we suggested to find horizontal and vertical relation after going through preparation process with inputted real-time license plate image of Korea and Japan, and then to classify license plate with using characteristic and geometric information of license plates. It classifies the extracted license plate images into letters and numbers, such as local name, local number, classification character and license consecutive numbers, and recognize license plate of Korea and Japan by applying hybrid and seven segments pattern vectors to classified letter and number region. License plate extraction step of the proposed system uses width and length information along with relative rate of Korean and Japanese license plate. Moreover, it exactly segmentation by letters with using each letter and number position information within license plate region, and recognizes Korean and Japanese license plates by applying hybrid and seven segment pattern vectors, containing characteristics related to letter size and movement within segmented letter area. As the result of testing the proposed system in real experiment, it recognized regardless of external lighting conditions as well as classifying license plates by nations, Korea and Japan. We have developed a system, recognizing regardless of inputted structural character of vehicle licenses and external environment.

This study intends to look into management and architectural space composition of Honjeon during the reign of Sukjong. Also it purposes to inspect how to affect management of the Royal Palace. The study is based on each Binjeon Honjeon Dogam Eugwe between late 17C and 18C. And the data on management of the Royal Palace is based on Joseonwangjosillok and Seungjeongwon Ilgi. Because Sukjong used ChangDeokgung and GyeongDeokgung alternately, Honjeon located at Munjeongjeon of ChangGyeonggung during Sukjong stayed at ChangDeokgung and located at Gyesangdang of GyeongDeokgung during Sukjong stayed at GyeongDeokgung. At that time, often movement of the King modified procedure of moving Honjeon. Between the first year of Hyenjong and the 9th year of Sukjong, architectural space of Honjeon was settled. In 1659, territory of Jeongjeon was settled. Also between 1674 and 1684, Goklimcheong was built. Construction of Goklimcheong is noticeable character. As Munjeongjeon was being used as Honjeon continually, it was recognized as Honjeon. Due to its long utilization as Honjeon, several gonvernment offices were transferred. Also it influenced utilization of Myeongjeongjeon.
