This study is for the characteristic of expression of exhibition presentation in 'The Korean peninsula' which is the Golden Lion Winner at the Venice Biennale in 2014. The Korean peninsula provides two opposite political and economic systems and adaptations of modernism through various multi media images. The curator, Minsuk Cho, presented cinema montage image of Collision for analyzing dynamic exhibition organization and provides the foundation of his theory from Bergson's image and duration to Deleuze's movement-image and time-image which is mentioned from Deleuze's book "cinema 1" and "cinema 2". Furthermore, the Korean peninsula has showed perception-image and affection-image from Eisenstein & Vertov's cinemathology and systemized exhibition presentation. The montage of Collision has maximized the movement from the variety and complexity in a collision and it made difference between information images which are space, time, emotion, intelligence, the tumult between subjectivity and objectivity, fragments from reorganizing itself, and distribution and art images. The limit of montage of Collision's dialectic is not only visual but also space from organic organization but the Korean peninsula overcomes its limit and shows leap of tactile perception and time-reflection from the montage of Collision's dialectic. Therefore, the exhibition of the Korean peninsula presents the conviction of adaptations of modernism.

Three-dimensional high-resolution magnetic resonance imaging (MRI) provides fine-level anatomical information for disease diagnosis. However, there is a limitation in obtaining high resolution due to the long scan time for wide spatial coverage. Therefore, in order to obtain a clear high-resolution(HR) image in a wide spatial coverage, a super-resolution technology that converts a low-resolution(LR) MRI image into a high-resolution is required. In this paper, we propose a super-resolution technique through filter learning based on information on the surrounding gradient information in 3D space from 3D MRI images. In the learning step, the gradient features of each voxel are computed through eigen-decomposition from 3D patch. Based on these features, we get the learned filters that minimize the difference of intensity between pairs of LR and HR images for similar features. In test step, the gradient feature of the patch is obtained for each voxel, and the filter is applied by selecting a filter corresponding to the feature closest to it. As a result of learning 100 T1 brain MRI images of HCP which is publicly opened, we showed that the performance improved by up to about 11% compared to the traditional interpolation method.

Recently, demand for designing own space is increasing as the rapid growth of home furnishing market. However, there is a limitation that it is not easy to compare the style between before construction view and after view. This study aims to translate real image into another style with GAN model learned with interior images. To implement this, first we established style criteria and collected modern, natural, and classic style images, and experimented with ResNet, UNet, Gradient penalty concept to CycleGAN algorithm. As a result of training, model recognize common indoor image elements, such as floor, wall, and furniture, and suitable color, material was converted according to interior style. On the other hand, the form of furniture, ornaments, and detailed pattern expressions are difficult to be recognized by CycleGAN model, and the accuracy lacked. Although UNet converted images more radically than ResNet, it was more stained. The GAN algorithm allowed us to represent results within 2 seconds. Through this, it is possible to quickly and easily visualize and compare the front and after the interior space style to be constructed. Furthermore, this GAN will be available to use in the design rendering include interior.

The purpose of this study is to analyze the collaboration and artification of the Issey Miyake fashion brand and to suggest the best course of artification that can secure the brand's value. The research methods are as follows: i) identifying the companies' strategy and flow through collaboration concepts and examples from Issey Miyake; ii) selecting Issey Miyake fashion brands and carrying out a literature review through websites, articles, and books; and iii) examining prior studies on the relationship between fashion and art. Results are as follows. The exhibition is divided into spaces for brand intangible assets, artistic collaboration with partners, art co-creation, and the aesthetics and tradition of the brand. Using exhibitions to share the artistic work of collaboration partners is expected to positively affect the brand's likability. The exhibit shares art collaborations in display cases for clothes and photographs. Artists and brands appear as an extension of the creative space and convergence design area. The artist's improvisation forms the creative space that communicates with the audience, and the convergence design area is expanded through the unifying organic connection between the various media in the fashion brand. The photographers and brands section displays the nature images of Pleats Please, as well as human and prism garment images. In these images, the viewer can perceive a story in the interplay between the human body and nature.

Linear array imaging sensors are widely used in remote sensing satellites. The final products of an imaging sensor can only be used when they are geometrically, radiometrically, and spectrally calibrated. Therefore, at the first stages of sensor design, a detailed calibration procedure must be carefully planned based on the accuracy requirements. In this paper, focusing on inherent optical distortion, a step-by-step procedure for laboratory geometric calibration of a typical push-broom satellite imaging sensor is simulated. The basis of this work is the simulation of a laboratory procedure in which a linear imager mounted on a rotary table captures images of a pin-hole pattern at different angles. By these images and their corresponding pinhole approximation, the correction function is extracted and applied to the raw images to give the corrected ones. The simulation results illustrate that using this approach, the nonlinear effects of distortion can be minimized and therefore the accuracy of the geometric position of this method on the image screen can be improved to better than the order of sub-pixel. On the other hand, the analyses can be used to proper laboratory facility selection based on the imaging sensor specifications and the accuracy.

In this paper, an automated segmentation algorithm is proposed for MR brain images using T1-weighted, T2-weighted, and PD images complementarily. The proposed segmentation algorithm is composed of 3 step. In the first step, cerebrum images are extracted by putting a cerebrum mask upon the three input images. In the second step, outstanding clusters that represent inner tissues of the cerebrum are chosen among 3-dimensional(3D) clusters. 3D clusters are determined by intersecting densely distributed parts of 2D histogram in the 3D space formed with three optimal scale images. Optimal scale image is made up of applying scale space filtering to each 2D histogram and searching graph structure. Optimal scale image best describes the shape of densely distributed parts of pixels in 2D histogram and searching graph structure. Optimal scale image best describes the shape of densely distributed parts of pixels in 2D histogram. In the final step, cerebrum images are segmented using FCM algorithm with its initial centroid value as the outstanding clusters centroid value. The proposed cluster's centroid accurately. And also can get better segmentation results from the proposed segmentation algorithm with multi spectral analysis than the method of single spectral analysis.

The purpose of this study is to set a relationship between intentional system and spatial orientation, and with space model in the human world to orient yourself is to present the basic spatial concepts. This is composed of parts of intentional system and spatial orientation on the research. Through the study of intentional system which is based on the orientation with Daniel Dennett's, it suggests the space-model that composed with aspects of intentionality and spatial elements. With space-model and judgement of spatial types, it makes relationship confirm between them. Through this process, following the results of this study were derived. First, intentional stance of space is the key for building knowledge and memories about space, and for identifying external environment images which are experienced in the senses of human. Second, changing the meaning from space to place makes horizons of space broader and creates a new sense of space with put the intentional orientation into the space. Third, this study can make confirm what the aspect of the space-schema-elements for orientation in space, serves as the presentation elements. This study leaps an old-view of the architectural customs about spatial orientation, and creates an opportunity to refine the newer concept of space. This concept of space is a basic essential for 'site-selection' and 'spot-catching' as an intentional system for spatial orientation and to establish a relationship with human beings in the world of his own orientation to the concept of space.

Space design in the 21st century has been developed in connection with media more various than ever. In the age of image represented by popular culture, space design connected with media is based on post-reason thoughts constituting the post-modern society, and reflects polysemously and pluralistically changes in the society through the identification of art with life. The movie, which is an image perceived particularly sensibly and the most impractical simulated image among various illusionary media images composing the contemporary society, is growing rapidly in interrelation with various fields of art based on its peculiar nature, and its influence is getting more extensive. The movie manipulates mass society to create what does not exist and restore lost images into new realities through the reproduction of extremely realistic senses, and uses them in establishing virtual realities and creating illusionary images representing the age of simularc. The illusionary expression of the movie produces new meanings through disintegrating existing meanings and recombining them, and expresses popular culture from a position closest to our everyday life. Such an analytical attitude toward the illusionary movie reflecting our society can be a new approach to space design. The present study attempts to suggest the possibility of applying such an illusionary characteristic of the movie as a methodology of space design by utilizing the characteristic as a conceptual language of space design.

We have made a comprehensive statistical study on the coronal mass ejections(CMEs) associated with helmet streamers. A total number of 3810 CMEs observed by SOHO/LASCO coronagraph from 1996 to 2000 have been visually inspected. By comparing their LASCO images and running difference images, we picked out streamer-associated CMEs, which are classified into two sub-groups: Class-A events whose morphological shape seen in the LASCO running difference image is quite similar to that of the pre-existing streamer, and Class-B events whose ejections occurred in a part of the streamer. The former type of CME may be caused by the destabilization of the helmet streamer and the latter type of CME may be related to the eruption of a filament underlying the helmet streamer or narrow CMEs such as streamer puffs. We have examined the distributions of CME speed and acceleration for both classes as well as the correlation between their speed and acceleration. The major results from these investigations are as follows. First, about a quarter of all CMEs are streamer-associated CMEs. Second, their mean speed is 413 km $s^{-1}$ for Class-A events and 371 km $s^{-1}$ for Class-B events. And the fraction of the streamer-associated CMEs decreases with speed. Third, the speed-acceleration diagrams show that there are no correlations between two quantities for both classes and the accelerations are nearly symmetric with respect to zero acceleration line. Fourth, their mean angular width are about $60^{\circ}$, which is similar to that of normal CMEs. Fifth, the fraction of streamer-associated CMEs during the solar minimum is a little larger than that during the solar maximum. Our results show that the kinematic characteristics of streamer-associated CMEs, especially Class-A events, are quite similar to those of quiescent filament-associated CMEs.
