사실적인 배우의 연기를 데이터로 추출하기 위해 모션캡쳐라는 장비를 이용하는데 추출된 데이터는 여전히 많은 후수정이 필요로 하고 있다. 모션의 보정이나 떨림, 그리고 디테일 수정 외에도 캐릭터들이 가방을 메거나, 물건을 들었다 놨다하는 경우에 모션 데이터들은 오브젝트들과의 실감나는 접촉을 만들기 위해 애니메이팅과 리깅의 작업이 필요하다. 또한 작업물이 게임엔진과 같은 타 소프트웨어로의 이동이 필요한 경우가 많아 작업공정이 복잡하게 되고 있다. 이는 상대적으로 모션캡쳐 데이터를 처리할 수 있는 업체들이 줄어들게 만드는 원인이 되고 있어 최근의 세계적인 영상콘텐츠 시장의 상황과는 대조적인 현상이라 할 수 있다. 이에 사실적인 디지털더블의 구현을 위한 모션캡쳐 데이터 처리 공정을 사례를 통해 효율적인 공정을 제시해보고 현 상황을 분석해 보려하였다.

Image denoising is considered as a key factor for capturing high-quality photos in digital cameras. Thus far, several image denoising methods have been proposed in the past decade. In addition, previous studies either relied on deep learning-based approaches or used the hand-crafted filters. Unfortunately, the previous method mostly emphasized on image denoising regardless of preserving or recovering the detail information in result images. This study proposes an detail extraction network to estimate detail information from a noisy input image. Moreover, the extracted detail information is utilized to enhance the final denoised image. Experimental results demonstrate that the proposed method can outperform the existing works by a subjective measurement.

본 논문에서는 위성 영상과 같은 원격 센싱 영상 등의 저 대비 영상의 화질을 개선하기 위하여 SVD (singular value decomposition)를 이용한 적응적 히스토그램 평활화 기법을 제안한다. 저 대비 영상의 특이값과 히스토그램 평활화 영상의 특이값을 결합하되, 사용자 파라미터를 통해 영상의 화질을 조절할 수 있도록 적응적 화질 개선 기법을 제안한다. 위성 영상을 비롯한 다양한 영상을 대상으로 실험한 결과 제안하는 방법이 기존의 히스토그램 평활화 기법 및 이를 개선한 방법에 비해 GSD (global standard deviation)으로 측정한 객관적 수치 측면에서 우수한 성능을 나타내고, 주관적 화질 측면에서 자연스럽고 영상의 어두운 영역 및 밝은 영역에서의 디테일 보존 성능이 우수함을 확인할 수 있다.

The behavior of the connection for beam-to-column weak axis connection and its details should be identified. Thus, each element is considered a panel zone, and the horizontal stiffener's presence or absence and position in bracket-type welding connection are used as variables to compare the behavior of strong axis connection and weak axis connection. In this study, the strength of connection is calculated by substituting the simple beam-strengthened vertical stiffeners for connection in the presence of horizontal stiffeners. In the absence of horizontal stiffeners, the strength of connection can be calculated using local flange bending strength considering local web yielding strength, web crippling, and web buckling strength. The results of the theoretical analysis and experiments are compared.

This study was to investigate the preference tendency by detail and material preference of summer one-piece dresses for the children, and evaluation standard of children's wear in purchasing one-piece dresses as an object of mothers who have girls as buying representatives of children's wear in order to supply real information of design about the one-piece dresses for the girls in accordance with the consumers' demands. The results of this study revealed that the one-piece dress was favorite one to them in purchasing their summer wear. This study showed tendency that the more the mother's fashion interest was, the more the mother's preference on the one-piece dress was. As to the material preference of one-piece dress, it preferred the natural fiber to the synthetic fiber much, and the preferred customer order in purchasing one-piece dresses for their children was analyzed as activity, material, design collar, and pattern. As to the preference by form factor of one-piece dress, it preferred A-line silhouette in the silhouette, natural waist in the waist position, 5~7cm from the knee in the length of one-piece dress, and flared skirt in shape of skirt. The preference on the collar type was soutien collar, and the preference on the neckline type was round neckline. In addition, the preference on sleeve form was shirtsleeve, and the preference on trimming was lace trimming.

Paul Rudolph's early work in Florida after World War II is a significant example of the regional transformation of typical Modern Architecture through the spatial composition based on the diversity and use of local material and construction methods. Paul Rudolph's concept of a Florida House design is the expression of regional material, construction, and structural system through the spatial extension & connection based on periodical, regional characteristics. The characteristics of the Florida works is the spatial extension & connection design based on the wood structural framework through the various design factors, such as a screen roof, open roof, and internal patio as the spatial extension and link method. Paul Rudolf designed the house using local materials, such as cypress wood and lime block produced near the Florida Area and provided details & technology considering the Florida climate and construction environment. Through studies of Paul Rudolph's Florida works, the Florida Houses can be a prototype of localization, and can be presented as the spatial & technical transformation of design by the historical, cultural, regional background.

Recently, the interest of precast concrete is increased for rapid construction in construction fields. Experimental study about the shear performance of the joint between hollow core slabs which have internal core to reduce their weight was performed. Main test variables were thickness of the topping concrete and existence of the wiremesh. Total 8 specimens including 4 in-plane shear and 4 out of plane shear were tested. Test results were analyzed in terms of cracking load, failure load, failure aspect, stiffness and ductility, and compared its design load to develop optimum design details. Test results indicated that the shear performance of the non-shrinkage mortar specimen was similar to that of 30mm thickness topping concrete specimen, and the effect of wiremesh reinforcement did not affect the failure load or stiffness of the specimens but the increase of ductility. And this paper presents the comparison results of the test results and design load to provide the optimum detail of the joint design between the hollow core slabs.

In this paper, we propose a new framework that can express the detailed movement of liquid sprayed from wet hair or fur. In wet hair, not only the friction and adhesion of the hair but also the movement of the liquid has a distinctive motion compared to the dry hair. However, the recently proposed techniques only considered the contact force and friction of the hair and did not improve the movement of the liquid dispersed in the wet hair. This problem is detrimental to the quality of the result because it does not capture the detailed features expressed in the interaction of hair and liquid. The main point of this paper is to alleviate this problem and improve the quality of the result. As a result, we propose a combining framework that can efficiently express FLIP (Fluid-implicit particle) based fluid simulation and interaction of hair particles. The proposed method expresses the movement of the liquid sprayed in a curved shape which was not expressed in previous studies.

In this study, the general structure of the landscape architecture industry was considered through analysis of advertisements in the landscape architecture magazine, 'Environment & Landscape Architecture', and the transition process and factors of landscape facilities were analyzed. Based on this result, the direction of future landscape facilities and basic data were suggested. When analyzing the advertisements that have been published in 'Environment & Landscape Architecture' for 30 years, outdoor facilities were depicted at a frequency of 1,853 times and among them, rest facilities and convenience facilities were depicted 1,457 times and 378 times, respectively. The reason why outdoor facilities have a far higher advertisement frequency than other landscape facilities is they were highly influenced by the house construction-related government policy, which resulted from the expansion of the rest facility industry along with regional expansion to public design. Moreover, it was found that wood and steel were mainly used to make pergolas and benches, which are rest facilities, and polycarbonate, with high economic efficiency and durability, was used the most as a roofing material for pergolas. This study attempts to explore the tendency of landscape facilities and the changes in the detail of their types by analyzing the stream of landscape facilities diachronically, based on the advertisements published in a representative magazine of landscape architecture.

스포츠웨어는 현대사회의 건강과 여가에 대한 관심으로 단순한 운동복의 수준을 넘어 우리 일상생활의 한 부분으로 점차 정착되고 발전되었다. 특히 현대 패션은 다기능성이 부각된 의류의 수요가 증가되고, 스포츠웨어와 캐주얼웨어의 혼합, 스포츠웨어의 디테일이나 이미지를 도입한 일상복의 확대 등으로 스포츠패션이 두드러지게 나타나고 있다(한은주, 2002). 스포츠웨어의 개념은 미국에서 출발하여 발전되어왔다.(중략)
