Assuming that different spatial types involves the change of observation time to acquire the spatial information, this study intended to analyze the observation time by interior space types and derive the proper time for spatial evaluation. Coming to the study method, in order to analyze the characteristics of observation time in the image evaluation of interior space by types, it looked into the observation time chosen by the testees during evaluation. The findings of this study are as follows: First, the observation time differed by genders and spatial types: men's average time was longest for modern (93.3 sec.) and natural (89.4 sec.) spaces; women's average time was longest for classic space (110.7 sec.), which was the shortest for men. Second, the intensity of observation time zone differed by spatial types: this finding can imply that different design types require different establishment of observation time for evaluation even if the spatial elements are the same. Third, analyzing the distribution of time zones chosen by most testees showed that men's observation time zones were more intensely distributed than those of women. Fourthly, the observation lime for general space could be derived from the gender-based comparison that excluded the difference by types, but considering that different design types lead to different observation time, it could be seen as proper for evaluation of interior space to establish the difference of observation time by spatial types. Finally, Analysis showed the highest preference to the time '(3)'. However, obtaining information presented is the most highly effective time is '(6). Thus, the preferred time zone is different and effective, according to the results of the analysis.

The film has always reflected the culture of the era based on reality and imagination. The visual effect in the film has mainly played a role of expressing the reality more realistically or recognizing the virtual as reality. This study examines the meaning and the effect of fantasy realism through Oasis of Lee Chang-dong. Fantastic realism has separated the reality from the imaginary space by using a dual meaning tool that affects the time and space in the film and reflects the human desire and desire to see. It was also reproduced in the real world through the medium of pigeons. In addition, it separates visualized space from non-visualized space in film narrative structure, separation of real and unreal space, segregation of consciousness and unconscious space, and separation of reality and reality space into power structure. With the development of technology, the image of the yellow image comes closer to us like reality, which will express the space of unconsciousness that we could not think of.

Recently, space branding has been used as a branding method for many companies because space communication is a way of utilizing space in a wide range of ways. However, generally speaking, communication only focuses on goods and information about brands and does not focus on consumer's stories. The purpose of this study is to present the communication of " Back to Harakenya " in concept of Harakeya as a solution to this problem and confirm its effectiveness through examples. We selected on the range of " cosmetics brand ", " food and beverage brand ", " brand brand " and " fashion brand " which can used as a direct experience as a marketing method, which is a good condition for communication. Based on that, Harakenya selected cases as spaces with the concept of "Back to Harakenya". Previously, Harakenya's concept of "Back to Harakenya" and his designs appears three features. First, it transforms into various being secondly, it generates active imagination and it contains at least as many things as possible. This resulted in the effect that people remember the image with a clear image. Based on this study, We investigated to draw a result of effects through how the design expression is made in the spaces of Space Branding and how the "Back to Harakenya" communication is taking place in the space. Through these studies, the design and communication method of Harakenya's "Back to Harakenya" concept helps us to remember the brand clearly and furthermore, we confirmed that the brand value can be improved.

We have successfully developed the KASI (Korea Astronomy and Space Science Institute) Solar Imaging Spectrograph (KSIS), which has been originally upgraded from the KASI solar spectrograph that was able to record solar spectra for a given slit region and to inspect the response function of narrow band filters. A prototype KSIS was developed in 2004 by using a scanning mirror in front of the spectrograph slit and a SBIG ST-8XE CCD camera. Its main disadvantage is that it took a long time (about 13 minutes) to scan a whole active region. In this work, we have upgraded the KSIS by installing a much faster Dalsa 1M15 CCD camera, which gives a data acquisition time of about 2.5 minutes. The software for KSIS was also improved for the new CCD camera on the basis of component-based development method. We have successfully made a test observation for a simple and small active region (AR10910) using the improved KSIS system. Our observations show that H-alpha images for several wavelengths have typical features in a sunspot as well as a H-alpha centerline image is quite similar to a BBSO H-alpha image, demonstrating the capability of the KSIS system.

In this study, in the field of remote sensing, where the scope of application is rapidly expanding to fields such as land monitoring, disaster prediction, facility safety inspection, and maintenance of cultural properties, monitoring of rural space and surrounding environment using UAV is utilized. It was carried out to verify the possibility, and the following main results were derived. First, the aerial image taken with an unmanned aerial vehicle had a much higher image size and spatial resolution than the aerial image provided by the National Geographic Information Service. It was suitable for analysis due to its high accuracy. Second, the more the number of photographed photos and the more complex the terrain features, the more the point cloud included in the aerial image taken with the UAV was extracted. As the amount of point cloud increases, accurate 3D mapping is possible, For accurate 3D mapping, it is judged that a point cloud acquisition method for difficult-to-photograph parts in the air is required. Third, 3D mapping technology using point cloud is effective for monitoring rural space and rural resources because it enables observation and comparison of parts that cannot be read from general aerial images. Fourth, the digital elevation model(DEM) produced with aerial image taken with an UAV can visually express the altitude and shape of the topography of the study site, so it can be used as data to predict the effects of topographical changes due to changes in rural space. Therefore, it is possible to utilize various results using the data included in the aerial image taken by the UAV. In this study, the superiority of images acquired by UAV was verified by comparison with existing images, and the effect of 3D mapping on rural space monitoring was visually analyzed. If various types of spatial data such as GIS analysis and topographic map production are collected and utilized using data that can be acquired by unmanned aerial vehicles, it is expected to be used as basic data for rural planning to maintain and preserve the rural environment.

Daylighting is the controlled admission of natural light into a space, reducing electric lighting and saving energy. By providing a direct link to the dynamic and perpetually evolving patterns of outdoor illumination, daylighting helps create a visually stimulating and comfort environment for building occupants, while reducing energy costs. Especially, however, glare is the most important factor in daylighting, which is issued by incoming direct sunlight into windows. This study analyzed the discomfort glare on a daylighting window by using Image processing methodology and found a solution to problems with glare source of occupants. There are several ways to evaluate discomfort glare such as UGR (Unified Glare Rating) of CIE, DGI (Daylight Glare Index, Hopkinson, 1972) and VCP (Visual Comfort Probability) of IES. These are used to apply to the relatively little artificial light source and they cannot cover discomfort glare from a real daylighting window. In this regarding, this paper aimed to calculate DGI index of the real daylighting window in a experimental space by using image processing methodology. The variables and outcomes are luminance distribution of non-shading window, effect of venetian blind installed on the window and locations related to position index of DGI.

We have researched the image of different forest species by asking those who use these forests how they feel when enjoying them for their various purposes. We surveyed five different forest areas, these were a pine forest a korean pine forest a cypress forest a broad leafed forest and a mixed forest. We asked 806 people how these forests made them feel and what they thought was the image of these forests. We offered them a choice of 18 pairs of adjectives to describe how they felt. We used the SD Scale and discovered 4 different factors. A feeling of comfort and freshness and a feeling of order and space. There was also a feeling of intimacy with nature. Each forest gave out its own feeling and image. comfort and freshness was felt by those in the pine forest, the korean pine forest, the broad leafed forest and the mixed forest. A Feeling of order and space was felt in the korean pine forest. Intimacy was felt in the pine forest, broad leafed forest and the mixed forest.

Recently, the number of techniques for analyzing medical images has been increasing in computer vision, employing X-ray CT images, ultrasound images, MR images, moire topographic images, etc. Spinal deformity is a serious problem especially for teenagers and medical doctors inspect moire topographic images of their backs visually for the primary screening. If a subject is normal, the moire image is almost symmetric with respect to the middle line of the subject's back, otherwise it shows asymmetric shape. In this paper, an image analysis technique is described for discriminating suspicious cases from normal in human spinal deformity by recognizing asymmetric moire images of human backs. The principal axes which are sensitive to asymmetry of the moire image are extracted at two parts on a subject's back and their angles are evaluated with respect to the detected middle line of the back. The two angles compose a 2-D feature space and inspected cases are divided into two clusters in the space by a linear discriminant function based on the Mahalanobis distance. Given 120 cases, 60 normal and 60 abnormal, the leave-out method was applied for the recognition and 75% recognition rate was achieved.

Automatic change detection based on the vector-to-raster comparison is hard especially in high-resolution image. This paper proposes a method to designate roads in high-resolution image in sequential manner using the information from vector map in which Hough transform is used for reliability. By its linearity, the road of urban areas in a vector map can be easily parameterized. Following some pre-processing to remove undesirable objects, we obtain the edge map of raster image. Then the edge map is transformed to a parameter space to find the selected road from vector map. The comparison is done in the parameter space to find the best matching. The set of parameters of a road from vector map is treated as the constraints to do matching. After designating the road, we may overlay it on the raster image for precise monitoring. The results can be used for detection of changes in road object in a semi-automatic fashion.
