Background and Objectives: Intravascular ultrasound (IVUS) evaluation of coronary artery morphology is based on the lumen and vessel segmentation. This study aimed to develop an automatic segmentation algorithm and validate the performances for measuring quantitative IVUS parameters. Methods: A total of 1,063 patients were randomly assigned, with a ratio of 4:1 to the training and test sets. The independent data set of 111 IVUS pullbacks was obtained to assess the vessel-level performance. The lumen and external elastic membrane (EEM) boundaries were labeled manually in every IVUS frame with a 0.2-mm interval. The Efficient-UNet was utilized for the automatic segmentation of IVUS images. Results: At the frame-level, Efficient-UNet showed a high dice similarity coefficient (DSC, 0.93±0.05) and Jaccard index (JI, 0.87±0.08) for lumen segmentation, and demonstrated a high DSC (0.97±0.03) and JI (0.94±0.04) for EEM segmentation. At the vessel-level, there were close correlations between model-derived vs. experts-measured IVUS parameters; minimal lumen image area (r=0.92), EEM area (r=0.88), lumen volume (r=0.99) and plaque volume (r=0.95). The agreement between model-derived vs. expert-measured minimal lumen area was similarly excellent compared to the experts' agreement. The model-based lumen and EEM segmentation for a 20-mm lesion segment required 13.2 seconds, whereas manual segmentation with a 0.2-mm interval by an expert took 187.5 minutes on average. Conclusions: The deep learning models can accurately and quickly delineate vascular geometry. The artificial intelligence-based methodology may support clinicians' decision-making by real-time application in the catheterization laboratory.

From the study on the relation of O-mi(五味) and Sam-Eum-Sam-Yang(三陰三陽), the conclusion is as follows. The system of Sam-Eum-Sam-Yang(三陰三陽) in human body expresses a kind of inner images[象] of continuous life, that implies many complex view-points, in both inside and out-side according to time flow. Besides, O-mi(五味) is one of very important native properties of all existences, that is accepted from the state they have been located in, and it includes the principles of real nature. Based on understanding of Sam-Eum-Sam-Yang(三陰三陽), when we investigate properties of O-mi(五味) for practical use, the concepts of contraction and extension[收散], softening and hardening[軟堅], and slowing and fastening[緩急], referred in Naegyeong(內經), directly express the images of Sam-Eum-Sam-Yang(三陰三陽).

This paper first introduces the concept of image as a key factor in recognition, and city identity as the dominant image of a region which is commonly possessed by individuals living and working in the region. Then, the new approach toward planning, the notion of self-organization associated with images and positive feedback mechanisms in terms of city vitalization, is discussed. Thirdly, carrying out the case study of a process in which Iida City in Japan has acquired a city identity as a puppet drama town, we present four stages in planning for city identity four stages and discuss the phenomena of city image self-organization. Finally, it is pointed out that multimedia are effective measures for the promotion of self-organization of city images, and that the role of local governments is very important in city planning to support the self-organization of cities.

As library have become changed. Beyond conventional simple functions such as data storing and recording, the functions of modern public libraries are expended to various directions, for example functions of encouraging residents to utilize information and participate in cultural activities and also a function of life-long education, resulting in playing a role as complex space. As the role of public libraries changes into a complex one, spatial planning reflecting this change is required. Spatial arrangements, furniture arrangements and interior images in 12 public libraries in Seoul were analyzed. As a result of the study, it was found that in spatial arrangements, many public libraries linked spaces by functions. Furniture arrangements have been changing from the closed arrangement to the open arrangement. Interior images were identified as static and simple except digital information space. Accordingly, public libraries have became needed to play a proper role of community facilities for local residents by planning furniture arrangements and conducting interior designs taking characteristics of many different users into consideration.

This study was aimed to analyze how images of information society were embodied in contemporary fashion design. To find out images of information society expressed in contemporary fashion design, this paper reviewed the characteristics of information society, and, found out six categories of contemporary fashion design in which the information society was expressed. Cyber environment causes techno style clothing which is characterized by the metallic or lustrous material and mechanical message. And interest in new materials increased significantly. Time-space compression makes the meaning of time and space change, therefore the past, present and future are coexist in the contemporary fashion design. The boundaries has loosed, so, heterogeneous materials and colors are used in fashion design all together. Variety and plurality affect expression of individuality and self-concept. Flexibility increased, so, soft and pliable clothing increased, too. Finally, quality of life is considered as more important value than quantity, so, luxurious look and zen style appear. Also, minimalism which is characterized as simplicity and purity affects the contemporary fashion design.
