Pavilions, follies, and installations provide a place with a new experience beyond that of simple garden architecture. From this point of view, this study tried to analyze the constructs in the Glass House site, which Philip Johnson has built for 50 years. After Chapter 1 Introduction, which summarized the background of the study, Chapter 2 investigated the design background of the landscape and the types of the constructs there. It also, studying literature on pavilions, follies, and installations, defined the basic meanings of them. Chapter 3 identified the features of each construct through the case studies of it, analyzing Johnson's intentions on it. These features are such as the applications of classical follies, the quotations of architectural history, fusion with art, architectural experiments, and the monuments of personal history. In conclusion, this study, finding the site specificity as a common feature of pavilions, follies, and installations, referred to two aspects of this, which are not only physical placeness but also cultural media.

Popular in the 1990s, Western Minimalism declined in popularity in the end of the century while the Oriental Mysticism and the Oriental Minimalism called “Zen Style” appeared. Fusion and Oriental Minimalism, both of which pursue traditional beauty and the essence of functionality and beauty, are combined with Japanese elements. As Oriental Minimalism is oriented towards Japan and China, we should consider the Japanese modernization process. Japan internationalized their own traditional elements after modernization. On the other hand, we only focus on tradition in a view of modernity, Japan developed their own culture whereas we followed the Western influences and trends after our culture and social structure were destroyed because of the civil war. Therefore, the aim of this paper is to find out the possibility of culture variety in interior design from the Japanese samples which modernized their culture in various sights. In other words, I researched and analyzed the expressive trends in Japanese Contemporary interior design, architecture and similarity and difference between Korea and Japan.

In autonomous driving cars, 3D pose estimation can be one of the effective methods to enhance safety control for OOP (Out of Position) passengers. There have been many studies on human pose estimation using a camera. Previous methods, however, have limitations in automotive applications. Due to unexplainable failures, CNN methods are unreliable, and other methods perform poorly. This paper proposes robust real-time multi-human 3D pose estimation architecture in vehicle using monocular RGB camera. Using particle filter, our approach integrates CNN 2D/3D pose measurements with available information in vehicle. Computer simulations were performed to confirm the accuracy and robustness of the proposed algorithm.

Cultural hybridization and global cross-fertilization, begun since the 1990s, mean the hybrid mixture of the low-class popular arts and the high-class fine arts and have found expression in intertextuality by means of the thinking system of de-constructuralist post-modernism. This study was intended to investigate the artistic intertextuality between fashion and art frontiere, especially between such fields as 'animation', 'music', and 'performing arts' and 'fashion', which shows the greatest characteristic of the phenomenon that the non-mainstream culture flows into the mainstream culture. It also aimed to investigate the intertextuality between 'technology' and 'fashion' as the delivery room of the youth culture and copycat culture due to the benefit of technologies since the 20th-century digital revolution. Animation as the neo-pop art with the popular code coming to the forefront in the 21th century integrated high-class fashion and low-class fashion into one through the combination of fashion and humor, and the musical element referring to the social difference of the cultural field and the social strata is becoming the 21th-century fashion icon through its fusion with the pictorial tendency along with the leisure-time life of the non-mainstream strata. In terms of intertextuality in performing arts, fashion style performs an important role in the presentation of performing arts and since the de-construction of the fin-de-ciecle form and its fusion with media have taken place, fashion works become and element of the origin that has an influence on a series of film, dance, dramatic elements and the like. The paradigm of technology made it socially and culturally possible to achieve the architecture of clothing system necessary for fashionable technical clothing by allowing the possibility of imitation, the function of technology to form popular culture. The intertextual tendency in the 21th-century fashion began from the de-constructive phenomenon of existing norms and now takes the multicultural character of surpassing a certain domain or concept. And it positions itself as the total art of spearheading the low-class culture and the non-mainstream culture as the hybrid domain of mainstream and non-mainstream cultures or high-class and low-class cultures.

On ship, especially on large ship, the flexure deformation between Master (M)/Slave (S) Inertial Navigation System (INS) is a key factor which determines the accuracy of the integrated system of M/S INS. In engineering this flexure deformation will be increased with the added ship size. In the M/S INS integrated system, the attitude error between MINS and SINS cannot really reflect the misalignment angle change of SINS due to the flexure deformation. At the same time, the flexure deformation will bring the change of the lever arm size, which further induces the uncertainty of lever arm velocity, resulting in the velocity matching error. To solve this problem, a $H_{\infty}$ algorithm is proposed, in which the attitude and velocity matching error caused by deformation is considered as measurement noise with limited energy, and measurement noise will be restrained by the robustness of $H_{\infty}$ filter. Based on the classical "attitude plus velocity" matching method, the progress of M/S INS information fusion is simulated and compared by using three kinds of schemes, which are known and unknown flexure deformation with standard Kalman filter, and unknown flexure deformation with $H_{\infty}$ filter, respectively. Simulation results indicate that $H_{\infty}$ filter can effectively improve the accuracy of information fusion when flexure deformation is unknown but non-ignorable.

The 4th industrial revolution needs a fusion of artificial intelligence, robotics, the Internet of Things (IoT), edge computing, and other technologies. For the fusion of technologies, cloud computing technology can provide flexible and high-performance computing resources so that cloud computing can be the foundation technology of new emerging services. The emerging services become a global-scale, and require much higher performance, availability, and reliability. Public cloud providers already provide global-scale services. However, their services, costs, performance, and policies are different. Enterprises/ developers to come out with a new inter-operable service are experiencing vendor lock-in problems. Therefore, multi-cloud technology that federatively resolves the limitations of single cloud providers is required. We propose a software platform, denoted as Cloud-Barista. Cloud-Barista is a multi-cloud service common platform for federating multiple clouds. It makes multiple cloud services as a single service. We explain the functional architecture of the proposed platform that consists of several frameworks, and then discuss the main design and implementation issues of each framework. To verify the feasibility of our proposal, we show a demonstration which is to create 18 virtual machines on several cloud providers, combine them as a single resource, and manage it.

Multi-exposure high dynamic range (HDR) image reconstruction, the task of reconstructing an HDR image from multiple low dynamic range (LDR) images in a dynamic scene, often produces ghosting artifacts caused by camera motion and moving objects and also cannot deal with washed-out regions due to over or under-exposures. While there has been many deep-learning-based methods with motion estimation to alleviate these problems, they still have limitations for severely moving scenes. They also require large parameter counts, especially in the case of state-of-the-art methods that employ attention modules. To address these issues, we propose a frequency domain approach based on the idea that the transform domain coefficients inherently involve the global information from whole image pixels to cope with large motions. Specifically we adopt Residual Fast Fourier Transform (RFFT) blocks, which allows for global interactions of pixels. Moreover, we also employ Depthwise Overparametrized convolution (DO-conv) blocks, a convolution in which each input channel is convolved with its own 2D kernel, for faster convergence and performance gains. We call this LFFNet (Lightweight Frequency Fusion Network), and experiments on the benchmarks show reduced ghosting artifacts and improved performance up to 0.6dB tonemapped PSNR compared to recent state-of-the-art methods. Our architecture also requires fewer parameters and converges faster in training.

원격탐사는 넓은 지역을 직접 접촉하지 않고 정보를 취득할 수 있고 다양한 분야에 적용할 수 있음으로써 급속히 발전하게 되었다. 이에 따라 위성의 제원 또한 원격탐사의 발전과 함께 급속한 발전을 이루게 되었다. 이러한 이유로 여러 분야에서 활용에 관한 연구가 활발히 이루어지고 있다. 현재 활용에 관한 연구는 활발히 이루어지고 있지만, 자료처리에 관련된 연구가 부족한 실정이다. 예전보다 인공위성의 제원이 발전하면서 많은 양의 정보 획득이 가능해진 것과 동시에 데이터 크기 또한 매우 커졌다. 이는 과거에 비해 자료의 처리속도가 저하된다는 단점이 존재한다. 따라서 본 논문에서는 병렬 처리의 한 가지 기법인 NVIDIA에서 제공하고 있는 CUDA (Compute Unified Device Architecture) 라이브러리를 활용하여 위성영상 자료처리 성능의 최적화를 목적으로 하고 있다. 본 연구의 순서는 다음과 같다. 다목적실용위성(Korea Multi-Purpose Satellite, KOMPSAT)의 영상을 크기를 기준으로 5가지 Type으로 나눈다. 이렇게 나누어진 영상을 원격탐사 분야의 한 가지 방법인 NDVI (Normalized Difference Vegetation Index)로 구현한다. 이때 CPU (Central Processing Unit, 중앙처리장치) 기반과 GPU (Graphic Processing Unit, 그래픽처리장치) 기반의 두 가지 방법과 상용 소프트웨어인 ArcMap을 이용하여 NDVI를 구현한다. 그리고 동일한 영상 유무를 판단하기 위해 구현된 결과 영상들을 히스토그램과 시각적으로 비교하고 CPU 버전과 GPU 버전의 처리속도를 비교 분석하였다. 연구결과 CPU 버전과 GPU 버전의 결과 영상은 ArcMap으로 구현한 영상과 시각적 그리고 히스토그램 비교를 통해 같은 결과를 나타내어 NDVI 코드는 올바르게 구현되었으며, 처리속도는 CPU보다 GPU가 약 5배 정도 빠른 것으로 확인하였다. 본 연구에서 병렬 처리의 한 기법인 CUDA 라이브러리를 활용하여 위성영상 자료처리 성능을 향상시킬 수 있었으며, 향후 NDVI와 같은 단순한 픽셀 연산 이외에도 다양한 원격탐사 기법의 적용이 필요할 것으로 사료된다.
