The parameters describing a complete hysteresis loop include pinch force, drift offset, effective stiffness, unloading and reloading trangential stiffness. Analytical equations proposed to quantify the nonlinear, inelastic behavior of reinforced shear walls can be used to predict these parameters as a function of axial load and drift ratio. For example, drift offset, effective stiffness, and first and second unloading and reloading tangential stiffness are calculated using equations obtained from test data for a desired drift ratio or ductility level. Pinch force can also be estimated for a given drift ratio and axial load. The effective virgin stiffness at the first yield and its post yield reduction can be estimated. The load deflection response of flexural reinforced concrete shear walls can now be estimated based on the effective wall stiffness that is a function of axial force and drift ratio.

Parody is credited for one of the forms of artistic presentation, and the utilization has been increasing day by day. However, there is no clear regulation in legislation or case. Parody is usually made without authorization to exploit of original author, so there is a lot of controversy over its infringement of copyright. Constitutional Law guarantees the freedom of expression and that of art, but it protects the author's right as well. So it is important how settle the collision of fundamental rights. It is expected the development of a variety of discussion on parody from the views of the basic value the Constitution pursues and the improvement and development of the culture that is the purpose of Copyright Act.

After analyzing data of 797 Middle and High School students, the results show that those using cognitive reappraisal strategies adjusted better in school life than those using expressive suppression strategies in regards to application of emotional regulation strategies. In gender differences of the application, male students adjusted better when they used cognitive reappraisal strategies in relationship with their teachers and their peers. Female students, on the other hand, adjusted better in relationship with their teachers their peers, and in academics, when using cognitive reappraisal strategies. In school year differences, middle school students who used less of emotional regulation strategies in academics, friendship and student-teacher relations adjusted better in relationship with their peers.

Multi-view video including depth image is necessary to develop a new compression encoding technique for storage and transmission, because of a huge amount of data. Layered depth image is an efficient representation method of multi-view video data. This method makes a data structure that is synthesis of multi-view color and depth image. This efficient method to compress new contents is suggested to use layered depth image representation and to apply for video compression encoding by using 3D warping. This paper proposed enhanced compression method using layered depth image representation and H.264/AVC video coding technology. In experimental results, we confirmed high compression performance and good quality of reconstructed image.

Due to the advancement of technology, there are many attempts trying to extend ways of expressing for using digital media, even in traditional theater. In the performances that were created before '미키쥐의 죽음' directors used videos only for the background, however, in 'A Death of Mickey Rat', trying to avoid the same patterns as the ones from the past creators realized an interactive performance with the balancing combination of videos, performer and sounds. As a result, the theater suggested a possibility of a new progress in creating theater by making a created space called the stage gain more reality and adding the power of interactivity between the media and the performer.

Due to recent developments in smart media, the desire for interaction between humans and computers has increased. In order to satisfy these needs, gesture recognition fields have been actively studied using image processing. In this paper, we propose a method to recognize Chinese hand numeric representation using image processing. The method binarizes an input image based on skin color to extract region of interest and check the number using the angular information of stretched fingers. Our proposed method has 95.83% of recognition rate.

Illustration is the work that brings out objective analyzing nature and things in many direction. Its purpose is to deliver the theme in an effective manner to appeal to the proper audience. Especially for 3 dimensional illustration, it is really important because its creativity can be complicated. Also, 3-D illustration are comprised of many materials and skills, so it is vital that 30D illustration is scientific and practical. In the research I am selecting on illustration that can be used in publishing and advertisements. I intend to give a clear understanding of 3-D illustration to my audience. In order to do that I have suggested an illustration must be developed through creativity strategy. Also through suggesting the condition of effective illustration, I want to help to set systematic and practical strategy of 3-D illustration.

In this paper, we discuss various methods to visualize high dimensional large-scale data and review some issues associated with visualizing this type of data. High-dimensional data can be presented in a 2-dimensional space with a few selected important variables. We can visualize more variables with various aesthetic attributes in graphics or use the projection pursuit method to find an interesting low-dimensional view. For large-scale data, we discuss jittering and alpha blending methods that solve any problem with overlapping points. We also review the R package tabplot, scagnostics, and other R packages for interactive web application with visualization.

본 논문에서는 서로 다른 개수의 정점을 가지는 두 다면체 사이의 점진적 다면체 모델 표현(Progressive Mesh Representation)을 계산하는 휴리스틱 방법을 제시한다. 정점의 개수가 각각 n, k개 인 두 다면체 모델 $M^n$, $M^k$ (n > k)에 대하여 $M^n$에서 서로 다른 k개의 정점을 선택한다. 선택된 k개의 정점을 기준으로 $M^n$의 모든 정점에 대한 클러스터링을 수행하여 k개의 정점군(Vertex Set)을 생성한다. $M^n$을 간략화하여 k개의 정점만을 가지는 모델 $M^{k'}$의 위상정보(Topology)를 $M^k$와 동일하게 유지하기 위하여 $M^n$ 정점군들의 위상정보를 수정한다. 수정 생성된 정점군 내에서 선분병합(Edge Collapse)을 수행하면, 위상정보를 유지하면서 $M^n$에서 $M^k$로 변화하는 점진적 다면체 모델 표현을 얻을 수 있다. $M^{k'}$과 $M^k$의 정점간의 기하학적 위치차이를 선형보간하여 선분병합이 일어날때 마다 반영하면 $M^n$에서 $M^k$로 기하정보를 부드럽게 유지하면서 변화하는 점진적 다면체 모델 표현을 얻을 수 있다. 본 논문의 연구결과는 기존의 DLoD(Discrete Level of Detail)를 지원하는 게임을 CLoD(Continuous Level of Detail)를 지원하는 게임으로 확장하는 등의 다양한 컴퓨터 그래픽스 응용문제에 사용할 수 있다.

In [1], it is shown that a subclass of ETBFs, which are self-dual ETBFs, can be expressed as a weighted average of median subfiltered outputs. In this paper, we extend this result to general ETBFs. In particular, we show that any ETBF can be represented as a weighted average of minimum (or maximum) subfiltered outputs. These representations naturally lead to a subclass of ETBF, called the K-th order ETBF (K-ETBF) that employs only those subfilters whose window sizes are less than or equal to K. By designing K-ETBFs under the mean square error criterion for various values of K and applying them to restore noisy signals, the tradeoff between the performance and the complexity of this class of filters is examined.
