무선 센서들의 진보에 따라 환자의 상태를 모니터링 하거나 정보를 저장 후 원거리에 있는 의사들의 진단 제공이 가능하게 되었다. 하지만 환자의 데이터의 양에 비해 의사의 수가 적으므로 환자가 진단을 제공 받는데 시간적인 한계가 있다. 따라서 본 연구에서는 환자의 상태를 1 차적으로 자동 진단하는 시스템을 제안한다. 전체 데이터의 적용을 위해 Circadian rhythm에 기반한 데이터 직접방법을 제안하고 데이터를 효율적으로 분류하기 위해 PSO(Particle Swarm Optimization)을 기반으로 하는 분류화 알고리즘을 적용하여 시스템의 수행속도 향상을 도모하였다.

The purpose of this study is to design appropriate digital tools for the production of makeup designs. In this study, we used a three-dimensional facial avatar simulation program developed by the Electronics and Telecommunications Research. This study is based on the creation of three-dimensional CG digital art of facial avatar makeup, produced by using simulation technology. First, the actual application and the tools for digital-optimization and media features were created, leading to the research and cleanup. Second, the theoretical background was applied to the formative elements of oriental colors in the designing process. Makeup design elements include point, line, surface, color, and texture. In this study, effective makeup design was interpreted to be based on the representation of particular elements, notably the design principles of balance, proportion, rhythm, repetition, emphasis, contrast, harmony, and unity. In Asia, design is based on the visibility of red, blue, black, yellow, and white-the colors of the five elements-and the use of points, lines, and shapes. This study was recently under scrutiny in relations to digital simulation and various three-dimensional designs, in terms of how to take advantage of a wide range of applications, and how to apply the findings through media and the dissemination of basic research. This study applies the characteristics of the limited existing stereoscopic three-dimensional and digital simulation programs in order to take advantage of the empirical research, providing a basis to implement this research in a meaningful way. A follow-up study is needed to extend these findings and theoretical foundation through continuous observation and in-depth technical development and research.

The study intends to seek the creative ideas that can satisfy the needs of individual consumers by rediscovering the modern meaning and the artistic value of geometric ornaments engraved on the backside of Danyugyung, which is a traditional Korean pattern. In terms of the study method, the symbolic meaning and formative characteristics of Danyugyung were determined, and the form of its pattern and the geometric characteristics were analyzed. Based on this, Photoshop and illustrations were used to apply the shapes of Danyugyung and internal patterns to the textile designs, and the results are as follows. Firstly, it was found that Danyugyung was associated with the bronze mirror, which was used from the Bronze Age to the Early Iron Age, and was the product of artistic activities and an object and acted as a shamanistic and authoritative symbol of the ruling parties, which were responsible for the acts related to the spiritual world. Secondly, it was discovered that forms of Danyugyung were classified into Jomungyung and Semungyung in accordance with Forms of Danyugyung (造飾), and the formative features of the geometric ornaments that were engraved in great detail on the backside could be found in the images which change according to the form of the inner patterns. Thirdly, with regard to the development of the textile designs utilizing the shape and inner patterns of Danyugyung based on the formative features, it was could discover that the simple shape of Danyugyung presented a value which can be applied as a unique design factor delivering a visual rhythm by attempting to create various harmonies overlapping lines engraved on the inner patterns and the shapes of Danyugyung. Based on the above-mentioned outcomes, the possibility was confirmed that Danyugyung can be used as a novel motif and as a standard unit of patterns for textile design. With future studies, I would like to utilize the unique and diverse images as pattern motif for textile design.

This study considers the modern expression of oriental esthetics by analyzing the fashion design with the Chinese ink technique based on the concept of Chi-Yun-Sheng-Tung, which was regarded as the best rule of art creation in oriental history. This study was performed by conducting a literature review of related books and advanced studies, and then, collection analysis was done with photos derived from fashion websites (seoulfashionweek.org, chinafashionweek.org, vogue.com, firstview. com) from 2010 S/S to 2016 S/S. A total of 317 fashion photos of designs created using the Chinese ink technique by Korean designers at Seoul Fashion Week and Chinese designers at China Fashion Week were analyzed. The contemporary fashions created with the Chinese ink technique were characterized by, first, the bold brush strokes and natural spreading effects of Chinese ink, second, the emphasis of empty space by taking essential elements, and third, the coexistence of deep Chinese ink colors with modern primary colors. The formativeness of the contemporary fashions created with Chinese ink technique based on Chi-Yun-Sheng-Tung were as follows: first, temperance, pursuing spiritual and minimal expression, second, empty space, making design elements interact and pursue harmony, third, changeable rhythm, symbolizing the growth and variation revealing the power of life, and fourth, vitality, represented in the rhythmical movement of the brush. This study was based on the oriental esthetics inherent in Chi-Yun-Sheng-Tung, and it attempted to analyze contemporary fashion design. The aim was to show the possibility of modern applications to traditional values, and it can be a meaningful case in design planning based on culture.
