We propose a novel non-photorealistic rendering technique which generates a cutout animation from a video for UCC. Our method consists of four parts. First, we construct an interactive system to build an articulated character. Second, we extract motions from an input video. Third, we transform motions of a character in order to reflect characteristics of cutout animations. Fourth, we render the extracted or transformed components in cutout animation style. We developed a unified system for a user to easily create a cutout animation from an input video and showed the system generated a cutout animation efficiently.

Transverse rib web of orthotropic steel decks is highly susceptible to stress concentration due to out-of-plane and oil canning deformation caused by longitudinal rib distortion. In particular, stress concentrations are observed in the crossing point of longitudinal rib-transverse rib-deck plate, and cutout parts of transverse rib. The main objective of this study is to improve structure performance and to reduce the stress concentration of aforementioned susceptible parts. It is known that the installation of diaphragm alleviates stress concentrations between crossing point ant cutout. The influence of transverse rib placement and cutout width on stress concentrations was thoroughly investigated through numerical analyses. The numerical result showed that diaphragms produce the structural details for improved structure performance, when the transverse rib was placed in the same location with diaphragms. In any case, it is certain that the installation of diaphragms has more advantageous than the case without diaphragms in terms of structure performance of orthotropic steel decks. In this study, the distance ratio($y_i/y_{total}$) is defined as the ratio of the distance($y_{total}$) between the deck plate and longitudinal rib bottom to the distance($y_i$) between the deck plate and crossing point of longitudinal rib-transverse rib in cutout part. It has been found that the optimal distance ratio was 0.85 from the numerical simulation.

This paper purposes to suggest subjects integration method for effective cut-out animation production education activity. So we suggest concrete method to integrate subjects focusing on animation production. We gave cut-out animation production lessons to a group of students. As a result, their degrees of study accomplishment were higher than those of students under a general teaching style. And we conducted a questionnaire survey of participants, they gave an affirmative answer in understanding, satisfaction, participation, interest. With this, we confirmed that the animation production class activity with integrated subjects raised the creative learning ability.

Orthotropic steel decks are manufactured by welding thin plates therefore it is inevitable that there are abundant works of welding process. On connection of transverse rib web, crossing point of longitudinal rib, transverse rib and deck plate and cut-out parts of transverse rib are the significant position of stress concentration phenomenon because of out of plane and oil-caning deformation caused by longitudinal rib distortion with shear force and distortion. In order to reduce the stress concentration phenomenon and improving fatigue performance at the crosing point and cut-out, structural analysis was performed considering the existence of scalop at conection and diaphragm which have same plane with transverse rib placed inside of longitudinal rib. Result o f the analysis show that there are the largest efect of stres concentration reduction when diaphragms are installed without scallop at connection, therefore these detail can improve the fatigue performance of orthotropic steel decks.

스마트폰의 보급이 늘어나면서 스마트폰을 이용한 인터넷 접속량 역시 빠른 속도로 증가하고 있다. 하지만, 스마트폰은 데스크탑 환경에 비해 제한적인 화면 크기를 가지고 있고 따라서 웹 브라우징을 할 때 확대, 축소, 스크롤 등의 작업을 반복적으로 수행해야 하는 단점을 지니고 있다. 이에 본 논문에서는 스케치 기법을 이용하여 사용자가 원하는 브라우징 영역을 지정하고 그 영역 안의 내용들을 분석하여 페이지를 재구성하고 컷아웃으로 화면 중앙에 출력하여 웹 브라우징을 간편화할 수 있는 컷아웃 기반의 브라우징 인터페이스를 제안한다.

We present a sketch-based animation interface that allows novice users to create informative 2D web animation quickly, In this paper, we uses cutouts as a main animated primitive to allow users to quickly create 'cutouts on whiteboard' style animations. Users can freely draw and write, and at the same time they can easily manipulate animated cutouts to create impressive animations, We demonstrate that our system is capable of creating more impressive animations more quickly than sketch-only animation approaches.

It is generally required to use modeling or animation tools for inserting dynamic objects into augmented reality, and this process demands high expertise and complexity. This paper proposes a video object based authoring method that enables augmentation with dynamic video objects without such process. Integrated grab-cut and grow-cut method strips initial area of video target off the existing video clips, and snap-cut method is then applied to track objects' boundaries over frames so as to augment real world with continuous motion frames. Experiment shows video cut-out and authoring results achieved by only a few menu selections and simple correcting sketch.

Orthotropic steel decks are manufactured by welding thin plates therefore it is inevitable that there are abundant works of welding process. On connection of transverse rib web, crossing point of longitudinal rib, transverse rib and deck plate and cut-out parts of transverse rib are the significant position of stress concentration because of out of plane and oil-canning deformation caused by longitudinal rib distortion with shear force and distortion. At the current research, the crossing point where the orthotropic steel decks's effect of improving fatigue performance are high, not placing scallop and diaphragm which have same plane with transverse rib placed inside of longitudinal rib at the same time, the reduce effects of stress concentration at the cut-out section and the crossing are high. Especially the installation of the diaphragm causing great effects based on research results to stress concentration appearance reduce effects at the cut-out section, putting radius of curvature of the diaphragm's top and bottom as a target, as a result of carrying out the parametric analysis an optimal diaphragm form that has great effects in fatigue performance came to a conclusion. Also based on optimal diaphragm form, an advantage of the diaphragm optimal setting position for improvement of the fatigue performance came to a conclusion.
