  • Recent complex visual culture is the visual world widely magnified according to the images like image, graphics, photograph, movie, and television, etc. by the development of digital technology. Because it conveys meanings and contents inserting sound and letters, it may have multimedia character conveying and communicating information beyond general language and letters. The vision for various images at that time is inseparably connected with language. And imaginative order of image and vision are composed of special way in culture and history. Language is different in society, culture, and history. Accordingly, if visual experience is communicated with language partially, it is difficult to have university. So, role of linguistic order plays an important role in forming and defining the social and cultural differences among the visual systems. Historically various visual and optical devices with this visual language have influenced a lot. These visual technologies are concrete and physical practice determining a way to get together with the subject and the visible object in the visible world. The visual language is connected with dimension like these symbols of images and the dimension like visual technologies to series of historical physical and institutional practices. It determines social visual mode toward object world in one of visual system. Accordingly, this study is to understand visual language with social and historical character according to the changed concept and characters as development of media technology. And it is to explain it in view of visual language as a dimension of symbol and visual technology of institutional and physical practice. After all, it cannot explain the effect on the function and visual mode of visual technology as its technical element only. It also cannot separate with the practice with coherent discourse and the physical and institutional practice. The possibility, technical element of technology contains, does not realize as it is but the effect is always communicated in the social veins and realized with a restriction.

  • In recent years, mobile phone has experienced an extremely fast evolution. It is equipped with high-quality color displays, high resolution cameras, and real-time accelerated 3D graphics. In addition, some other features are includes GPS sensor and Digital Compass, etc. This evolution advent significantly helps the application developers to use the power of smart-phones, to create a rich environment that offers a wide range of services and exciting possibilities. To date mobile AR in outdoor research there are many popular location-based AR services, such Layar and Wikitude. These systems have big limitation the AR contents hardly overlaid on the real target. Another research is context-based AR services using image recognition and tracking. The AR contents are precisely overlaid on the real target. But the real-time performance is restricted by the retrieval time and hardly implement in large scale area. In our work, we exploit to combine advantages of location-based AR with context-based AR. The system can easily find out surrounding landmarks first and then do the recognition and tracking with them. The proposed system mainly consists of two major parts-landmark browsing module and annotation module. In landmark browsing module, user can view an augmented virtual information (information media), such as text, picture and video on their smart-phone viewfinder, when they pointing out their smart-phone to a certain building or landmark. For this, landmark recognition technique is applied in this work. SURF point-based features are used in the matching process due to their robustness. To ensure the image retrieval and matching processes is fast enough for real time tracking, we exploit the contextual device (GPS and digital compass) information. This is necessary to select the nearest and pointed orientation landmarks from the database. The queried image is only matched with this selected data. Therefore, the speed for matching will be significantly increased. Secondly is the annotation module. Instead of viewing only the augmented information media, user can create virtual annotation based on linked data. Having to know a full knowledge about the landmark, are not necessary required. They can simply look for the appropriate topic by searching it with a keyword in linked data. With this, it helps the system to find out target URI in order to generate correct AR contents. On the other hand, in order to recognize target landmarks, images of selected building or landmark are captured from different angle and distance. This procedure looks like a similar processing of building a connection between the real building and the virtual information existed in the Linked Open Data. In our experiments, search range in the database is reduced by clustering images into groups according to their coordinates. A Grid-base clustering method and user location information are used to restrict the retrieval range. Comparing the existed research using cluster and GPS information the retrieval time is around 70~80ms. Experiment results show our approach the retrieval time reduces to around 18~20ms in average. Therefore the totally processing time is reduced from 490~540ms to 438~480ms. The performance improvement will be more obvious when the database growing. It demonstrates the proposed system is efficient and robust in many cases.

  • Image analyses for sheared joint specimens are performed to study asperity degradation characteristics with respect to the roughness mobilization of rock joints. Four different types of joint specimens, which are made of high-strength gypsum materials, are prepared by replicating the three-dimensional roughness of rock joints. About twenty jointed rock shear tests are performed at various normal stress levels. The characteristic and scale of asperity degradation on the sheared joint specimens are analyzed using the digital image analysis technique. The results show that the asperity degradation characteristic mainly depends on the normal stress level and can be defined by asperity failure and wear. The asperity degradation develops significantly around the peak shear displacement and the average amount of degraded asperities remains constant with further displacement because of new degradation of small scale asperities. The shear strength results using high-strength gypsum materials can not fully represent physical properties of each mineral particles of asperities on the natural rock joint surface. However the results of this quantitative estimation for the relationship between the peak shear displacement and the asperity degradation suggest that the characterization of asperity degradation provides an important insight into mechanical characteristics and shear models of rock joints.

  • 앙드레 꾸레쥬는 자신의 디자인에 건축적 조형미를 표현한 대표적인 디자이너이다. 그의 디자인들은 라인 뿐 아니라 색채, 소재, 액세서리에 이르기까지 건물을 짓듯이 설계, 구성되어 있다. 최근 복식미의 건축적 조형성이 강조되고 있는 것을 감안할 때, 60년대 이미 선구자적인 역할을 하면서 자신의 건축가적인 기호를 유감없이 발휘해온 꾸레쥬를 연구한다는 것은 21세기를 향한 패션의 발전 측면에서 조금이라도 의미가 있지 않을까 생각한다. 본 연구에서는 앙드레 꾸fp쥬가 가장 활발히 활동했던 1974년에서 1970년까지 그의 디자인들을 집중 연구하였는데, 그의 패션디자인에 건축양식의 특징들이 어떻게 나타났는지에 연구의 초점을 맞추었다. 본 연구의 대상으로 사용된 실제의 옷 샘플들은 뉴욕 메트로폴리탄 예술박물관내의 Costume Institute Storage 에 있는 의복과 액세서리들을 직접, 관찰 , 분석한것이고 그 박의 사진들은 패션과 건축에 관한 서적과 잡지, 박물관내의 Slide Library , 그리고 Costume Institute Library Collection에서 발췌 , 비교 연구한 것이다. 일찍이 엔지니어링과 건축을 공부했던 앙드레 꾸레쥬는 50년대의 패션 디자이너의 거장 발렌시아가 밑에서 10년 넘게 일하다가 독립하였는데 그의 디자인 세계는 줄곧 여성들이 입고 편히 활동 할 수 있는 기능성을 강조하면서 단순하고 편안한 의복 구성에 중점을 두었다. 그리고 그는 이러한 자신의 패션 철학과 의복제작 과정들은 현대건물이 갖는 단순성, 기능성의 특징과 일치한다고 믿었다. A. 라인(Line) 앙드레 꾸레쥬는 패션 디자인에서의 비레는 건축에서구조를 쌓아가는 것과 같은 것이라고 생각하고 옷에서의 기본 구성을 기하학적인 라인에 두었다. 그래서 그의 옷들은 A-라인, 사각형, 사다리꼴,,, 등의 분명한 실루엣을 이루고 있는데 이러한 기본라인을 뒷받침이라도 하듯 소매가 아주 짧거나 없는 것이 특징이다. 황금분할이 아닌 1 : 1 구성은 그가 독특하게 사용한 비례방법의 하나인데 그것은 자켓과 스커트의 길이비례, 요크와 몸판간의 면적비례 등에서 잘 나타나고 있다. 그리고 그는 , 의복구성의 비례를 강조하기 위해 사용한 강한 색상의 대비를 현대건물의 인테리어에 빛을 사용하는 것과 같은 이치라고 설명한다. B.색상(Color) 흰색은 그러한 그의 비례강조 의복에 가장 적절한 색으로 사용되었다. 그는 빨강, 오렌지, 녹색, 분홍등 강렬한 원색을 사용하였는데도 불구하고 흰색은 그의 건축양식 발상의 Ideo를 완성시키는 완전한 색이었다. 뜨거운 날씨에 흰색이 가장 기능적인 색인 것처럼 강한 원색 대비를 통해 비례강조를 하면서 동시에 그것을 뒷받침하는 가장 합리적이고 기능적인 색은 흰색이라고 믿었다. C. 소재 (Material) 앙드레 꾸레쥬는 건물을 짓듯이 사람위에 옷을 건축한다고 믿었기 때문에 자연히 둔탁하고 딱딱한 소재가 많이 사용되었다. 비닐, 금속류, 시퀸스처럼 광택나고 투명한 재료 선호는 그 당시 현대 건축에서 선풍적으로 많이 사용되었던 유리, 금속류, 크리스탈 등 비치고 광택나는 건축재료와 일맥상통하는 것이다. 그러한 선국적인 내료 사용결과로 보여진 괴상하고 선정적인 그러면서도 아주 단순한 패션은 미래 지향적인 건축양식 구조의 " Simple", "Plain" 느낌과 정확하게 같은 것이다. 이상과 같이 앙드레 꾸레쥬는 옷을 디자인 했다기 보다는 건축했다. 주목할만한 점은 60년대 말 당시 발표되었던 그의 건축 구조적인 디자인의 특징들이 21세기를 앞둔 90년대에 다시 크게 유행하고있다는 점이다. 꾸레쥬 역시, 최근 자신의 디자인을 통해 건축적 조형미와 미래지향적 이미지를 더욱 강조하고 있는 것을 볼 수있다. 단순하면서 우주공간을 선회하는 듯한 입체적인 라인, 흰색을 비롯한 자연에 가까운 색을 중심으로 하되, 밝은 색조의 하이라이트, 플라스틱, 금속류와 같이 딱딱하고 광택나며 비치는 재료 사용,, 등등이 바로 그것이다. 그리고 이러한 그에 미래 지향적이고 조형적인 디자인들은 앞으로 어떻게 더 모험적인 모습으로 선보일지 우리 모두가 주목할만한 일인 것이다.

  • Changgyeongwon emerged as pleasure grounds following the creation of a museum, zoo and botanical garden in Changgyeonggung Palace during the Japanese colonial period. Pleasure grounds offer space for entertainment and have maintained the image of a paradise apart from reality. This study examined the creation process of pleasure grounds within a royal palace and the following spatial changes. By analyzing the image of Changgyeongwon as an artificial paradise, this study explored its landscape and cultural aspects. Literature reviews on the intention and process showed that the Changgyeongwon pleasure grounds were created as a 'royal garden' for the amusement of Sunjong, as well as 'public pleasure grounds' in the process of colonization. It was one of the first public spaces open to everyone who could afford the entrance fee. The layout of Changgyeongwon was studied by a comparison and analyzation of modern plans and photographs. It was composed of the central museum zone, northern botanical garden zone, and southern zoological garden zone. A conservatory and greenhouse to exhibit and maintain tropical plants were intensively built in the botanical garden zone while an aviary was created on the zoo pond. In the vicinity of the aviary a vivarium was constructed. Museum exhibition facilities included a main building as well as existing buildings, and a western flower garden was created between the buildings. Space for children including a playground and horse-riding course were created in the 1930's. The paradisiacal image and pleasure grounds culture of Changgyeongwon were studied as follows. Firstly, it shows that Changgyeongwon's paradisiacal image where rare animals and exotic plants were open to the public was promoted by the zoo and botanical garden. This led to the creation of new popular leisure activities such as flower appreciation and animal watching. Secondly, Changgyeongwon offered an urban leisure space, symbolizing the 'non-urban nature within the city' where the urban residents could escape from the daily routine. Thirdly, Changgyeongwon was known for its 'fantastic night landscape' by its night opening during the cherry blossom season. This cherry blossom viewing at night sadly degenerated by various shows and drinking, and as a result, an image of a deviant paradise was given to Changgyeongwon. Changgyeongwon contributed to creating a new space with its diverse facilities, and the public embraced the urban culture through experiences of pleasure and entertainment.

  • In this paper, we suggest an application system architecture which provides accurate, fast and efficient automatic gasometer reading function. The system captures gasometer image using mobile device camera, transmits the image to a cloud server on top of private LTE network, and analyzes the image to extract character information of device ID and gas usage amount by selective optical character recognition based on deep learning technology. In general, there are many types of character in an image and optical character recognition technology extracts all character information in an image. But some applications need to ignore non-of-interest types of character and only have to focus on some specific types of characters. For an example of the application, automatic gasometer reading system only need to extract device ID and gas usage amount character information from gasometer images to send bill to users. Non-of-interest character strings, such as device type, manufacturer, manufacturing date, specification and etc., are not valuable information to the application. Thus, the application have to analyze point of interest region and specific types of characters to extract valuable information only. We adopted CNN (Convolutional Neural Network) based object detection and CRNN (Convolutional Recurrent Neural Network) technology for selective optical character recognition which only analyze point of interest region for selective character information extraction. We build up 3 neural networks for the application system. The first is a convolutional neural network which detects point of interest region of gas usage amount and device ID information character strings, the second is another convolutional neural network which transforms spatial information of point of interest region to spatial sequential feature vectors, and the third is bi-directional long short term memory network which converts spatial sequential information to character strings using time-series analysis mapping from feature vectors to character strings. In this research, point of interest character strings are device ID and gas usage amount. Device ID consists of 12 arabic character strings and gas usage amount consists of 4 ~ 5 arabic character strings. All system components are implemented in Amazon Web Service Cloud with Intel Zeon E5-2686 v4 CPU and NVidia TESLA V100 GPU. The system architecture adopts master-lave processing structure for efficient and fast parallel processing coping with about 700,000 requests per day. Mobile device captures gasometer image and transmits to master process in AWS cloud. Master process runs on Intel Zeon CPU and pushes reading request from mobile device to an input queue with FIFO (First In First Out) structure. Slave process consists of 3 types of deep neural networks which conduct character recognition process and runs on NVidia GPU module. Slave process is always polling the input queue to get recognition request. If there are some requests from master process in the input queue, slave process converts the image in the input queue to device ID character string, gas usage amount character string and position information of the strings, returns the information to output queue, and switch to idle mode to poll the input queue. Master process gets final information form the output queue and delivers the information to the mobile device. We used total 27,120 gasometer images for training, validation and testing of 3 types of deep neural network. 22,985 images were used for training and validation, 4,135 images were used for testing. We randomly splitted 22,985 images with 8:2 ratio for training and validation respectively for each training epoch. 4,135 test image were categorized into 5 types (Normal, noise, reflex, scale and slant). Normal data is clean image data, noise means image with noise signal, relfex means image with light reflection in gasometer region, scale means images with small object size due to long-distance capturing and slant means images which is not horizontally flat. Final character string recognition accuracies for device ID and gas usage amount of normal data are 0.960 and 0.864 respectively.

  • With the development of digital technologies, CAID became an essential part in the industrial design process. Creating photo-realistic images from a virtual scene with 3D models is one of the specialized task for CAID users. This task requires a complex interface of setting the positions and the parameters of camera and lights for optimal rendering results. However, the user interface of existing CAID tools are not simple for designers because the task is mostly accomplished in a parameter setting dialogue window. This research address this interface issues, in particular the issues related to lighting, by developing and evaluating TLS(Tangible Lighting Studio) that uses Augmented Reality and Tangible User Interface. The interface of positioning objects and setting parameters become tangible and distributed in the workspace to support more intuitive rendering task. TLS consists of markers, and physical controller, and a see-through HMD(Head Mounted Display). The user can directly control the lighting parameters in the AR workspace. In the evaluation experiment, TLS provide higher effectiveness, efficiency and user satisfaction compared to existing GUI(Graphic User Interface) method. It is expected that the application of TLS can be expanded to photography education and architecture simulation.
