New images percolate through human consciousness by the media such as movies, TV programs, and brilliant advertisements. These images reproduce new ' things ' throughout the ' semantic processes ' by those who experience and recognize them. Alvin Toffler describes it as the ' information bomb ' and ' image fragments ' in his talk about the new paradigm of information-oriented era. The increasing number of images and their accelerating rate of appearance imply that images become more momentary, and are evidence that they are transforming entire human life and consciousness. Such awareness means a lot to a designer. Especially, the subject that how modern space-dominating images are related to the structure and materials constituting the space and communicate with human mind will be an important factor in establishing the human-space relationship in the future. Furthermore, the present age overspread with various medium is not the only one privileged of the images that exist within space. They are the results of continuous expansion of existing images, and also process of evolution of space powered by the fusion of images and digital media. Imagified space is a boundary layer of Cyberspace, and the space itself becomes an interface by human recognition and participation. Now, the functional classification of spaces such as ' office, ' ' cafe, ' and ' school ' is meaningless. Whatever it may be, the function of a space is defined by the information it interfaces, and therefore it becomes an interface to information through a large number of images. Based on this idea, we will observe the imagificaiton of space in the form of discussion, and from that, try to understand the phenomenon through the real world examples.

Korea multi-purpose satellite-5 (KOMPSAT-5) is a low earth orbit (LEO) satellite scheduled to be launched in 2010. To satisfy the precision orbit determination (POD) requirement for a high resolution synthetic aperture radar image of KOMPSAT-5, KOMPSAT-5 has atmosphere occultation POD (AOPOD) system which consists of a space-borne dual frequency global positioning system (GPS) receiver and a laser retro reflector array. A space-borne dual frequency GPS receiver on a LEO satellite provides position data for the POD and radio occultation data for scientific applications. This paper describes an overview of AOPOD system and operation concepts of the radio occultation mission in KOMPSAT-5. We showed AOPOD system satisfies the requirements of KOMPSAT-5 in performance and stability.

This study aims to investigate the changing roles of Local Government and the ways to improve the space plan, especially focusing on the Local Government civil service space of Seoul City. Recently, many Local Government have endeavored to get rid of the authoritative images and change themselves to a space featuring cultural functions and efficient performance. Local Government buildings in Seoul City are trying to decorate the inner and outer images through new construction or extension of buildings so as to become more friendly to residents. Such efforts are visualized especially in civil service space. Civil service space represents the whole image and role of the Local Government. In addition, civil service space and resting space, which are frequently used, are correlated and more and more accessible to each other as administrative and civil services are increasing. By integrating and developing such features, civil service space of Local Government that meets the requirements of the new era will be presented.

In this study, we examined chromospheric oscillation signatures in two solar active regions, a limb active region and a sunspot with a light bridge, observed by the Fast Imaging Solar Spectrograph (FISS) of the 1.6m New Solar Telescope (NST) at Big Bear Solar Observatory. The FISS is a slit spectrograph with a fast imaging capability and can observe the solar chromosphere in $H{\alpha}$ and Ca II $8542{\AA}$ bands simultaneously with high spectral resolutions. After dark and flat correction, we compensated for image rotation at the Coude focus and made image alignment. We estimated Doppler shifts over active regions using the bisector method and investigated the temporal and spatial fluctuations of Doppler shifts for some selected cases. And we obtain the power map by using the Lomb-Scargle periodogram technique to examine the oscillation power at different features. Finally, we will discuss our results and implications.

Contemporary design environment is formed with image-centered trend based on pluralism. In this point of view, enterprises' building lobbies are public places containing the equivocal meaning, actively utilizing light as a design element to express the image of enterprises' identifications. Light is an immaterial entity having unlimited possibilities and potentials on space. It also acts as media to activate spaces and create new images in connection with formative elements of space. This study is to figure out how lightings are expressed and affected the formative characteristics of office lobby spaces and activate the specific characteristics of spaces. As a result, we drew conclusions as follows. First, as state-of-the-art technology and media are introduced, light is expressed on spaces as floating, direction, rhythm, silhouette, metaphor and allusion, sense of depth and volume. Second, expressive aspects of light in lobby space are embodiment of light, substantiation of immateriality, standing of materiality from the perspective of spatial aesthetics, and distortion/transformation of shape, pluralism phenomena of space from the perspective of spatial structure. In this way, light on building lobbies which are greatly required design differentiation strategy, specializes space and also integrates all the designs as not only a functional element but also a mental, psychological, formative element. Consequently, light on lobby spaces induces communication between spaces and users, makes formative value of existence in itself, and presents the characteristics of differentiated enterprises' identities.

The Korea Astronomy and Space Science Institute (KASI) is developing three 1.6m optical telescopes with $18k{\times}18k$ mosaic CCD cameras. These telescopes will be installed and operated at Chile, South Africa, and Australia for Korea Micro-lensing Telescope Network (KMTNet) project. The main scientific goal of the project is to discover earth-like extra-solar planets using the gravitational micro-lensing technique. To achieve the goal, each telescope at three sites will continuously monitor the specific region of Galactic bulge with 2.5 minute cadence for five years. Assuming 12 hour observation in maximum for a night, the amount of 200 GB file storage is required for one night observation at one observatory. If we consider the whole project period and the data processing procedure, a few PB class data storage, high-speed network, and high performance computers are essential. In this presentation, we introduce the KMTNet data management plan that handles gigantic data; raw image collecting, image processing, photometry pipeline, database archiving, and backup.

본 작품은 jitter의 multiplex기능을 이용한 디지털 아트작품으로 두 가지 영상의 cross concept를 이용한 인터렉티브 영상 설치 작품이다. 평면스크린이 아닌 형광등을 이용하여 특수 제작한 스크린을 통해, 형광등에 비춰지는 영상과 그 틈새로 벽에 비춰지는 두 가지 영상을 보여주게 된다. 실시간으로 카메라에 의해 받아들여진 관객의 모습과 제작해 놓은 두 가지 영상은 jitter의 multiplex기능에 의한 합성과정을 거쳐 형광등 스크린에만, 또는 벽에만 비춰지게 된다. 한 영상이지만 관객의 모습은 벽과 형광등을 오가며 관객을 혼란에 빠트리게 된다. 제작한 영상과 실시간으로 입력되는 관객의 두 가지 모습은 상반, 또는 병치의 느낌으로 관객에게 다가가게 되며 그것은 인간의 이중성을 표현하게 되는 동시에 물리적인 존재공간과 우리가 느끼는 시각적 공간을 구분하여 서로 다른 지배 문법이 있다는 것을 표현하게 된다. 퍼스펙티브와 환경에 의해 왜곡되는 영상재현의 과정을 보여주기 위해 형광등으로 제작한 스크린과 cross concept의 영상을 제작 사용하였다.

영상을 검색하는 데에는 형태, 색상, 질감 등 여러 가지 특징을 사용 할 수 있다. 그 중 가장 활발한 연구가 이루어지고 있는 분야가 형태 정보와 색상 정보를 이용하는 분야이다. 형태 정보를 이용하는 검색 방법에는 2D 모멘트와 푸리에변환 등의 방법이 유명하다. 또 다른 방법으로는 CSS(Curvature Scale Space)가 있는데, 이는 윤곽선 정보를 이용하여 윤곽선의 굴곡을 2D 그래프로 표현하여 그 그래프의 극대점을 특징 값으로 사용하여 영상을 비교 검색하는 방법이다. 기존 CSS 방법에는 몇 가지 문제점이 있어서 본 논문에서는 기존 방법을 향상시킨 ICSS 방법을 사용하여 영상을 검색한다. 색상 정보를 이용하는 방법에는 RGB 색상정보를 이용하는 방법과 HSI 색상정보를 이용하는 방법 등이 있는데 본 논문에서는 HSI 색상정보를 이용하여 색상 히스토그램으로 표현한 후 영상의 비교 척도로 사용하였다. 영상의 유사도를 측정하는 방법으로는 유클리디언 디스턴스를 주로 사용하는데, 본 논문에서는 정확도와 검색 시간을 단축시키고자 DTW를 사용하여 영상의 유사도를 측정하였고, 유클리디언 디스턴스를 사용했을 때와 비교하여 성능 향상 결과를 보인다.

컴퓨터와 인터넷의 발달로 정보의 형태가 다양화 되어 문서 위주의 자료들로부터 이미지, 오디오, 비디오, 음성 등의 모습으로 혼합되어 가고 있다. 하지만 대부분의 검색은 문서 위주로 하기 때문에 이미지, 오디오, 비디오 등은 파일의 이름이 명확하게 설정되어 있지 않을 경우에는 검색을 할 수 없다. 이러한 문제점을 해결하기 위해 문서가 아닌 내용을 기반으로 검색하는 방법을 내용 기반 검색이라고 한다. 그리고 이미지의 내용을 기반으로 검색하는 방법을 내용 기반 이미지 검색이라고 한다. 본 논문에서는 HSI 컬러 공간, ART2 알고리즘, SOM 알고리즘을 이용한 내용 기반 이미지 검색 방법을 제안한다. 제안하는 방법은 학습 대상을 선정하기 위해 원 영상의 특징을 분할한다. 그리고 사용자가 학습 대상을 선정하도록 하기 위해 분할된 특징을 SOM 알고리즘에 적용하여 비슷한 특징을 가지는 영상들로 군집화 한다. 군집화된 영상들에 대해 사용자가 학습 대상을 선정하여 ART2 알고리즘에 적용하여 학습한다. 제안한 방법을 적용하여 이미지 검색을 실험한 결과 제안된 방법은 하나의 이미지가 여러 개의 키워드를 가질 수 있기 때문에 이미지에 포함된 정보를 효과적으로 검색하는 것을 확인하였다.
