Fractal geometry based upon the latest complex theory shows different features of design pattern quite different from the past. It is not yet sure which kind of effects it would bring about in the future, we think that it would help to create various spaces and organic design vision. Therefore we will look into the significances and adaptabilities in space design by studying fractal design principles of today's new model in space design

We present our analysis of a newly discovered galaxy-galaxy gravitational lens system in the First Look Survey (FLS) field. This object shows a highly distorted background galaxy (z=0.245) image by a nearby elliptical galaxy (z=0.08), which can be interpreted as a result of gravitational lensing. We model the lens with elliptical isothermal sphere model, and present the mass and potential distribution of the system.

In order to eliminate position errors existing at the steady state in the motion control of robotic maniprlators, a new fuzzy control algorithm is proposed using three variables, position error, velocity error and integral of position errors as input variables of the fuzzy controller, This controller is applied to the tracking control of robotic manipulators in Cartesian space. Three dimensional look-up table is used to reduce the computational time in rel-time control. Simulation and experimental studies are conducted to evaluate the control performance for the two axis direct drive SCARA robot system.

본 논문에서는 일반적 형태의 고차원 펄스신호에 대한 푸리에 변환을 구하는 새롭고 용이한 방법을 제안한다. 우선 일반적 형태의 부분응답 전송시스템 모델을 수정하여 n-차 펄스신호의 푸리에 해석을 위한 새로운 모델을 설정하고, 그로부터 차수에 대하여 순환적으로 작용하는 대표 관계식을 유도한다. 이러한 대표 관계식으로부터 목록 찾아보기 방식의 푸리에 변환법을 위한 일반적 뼈대공식을 형성시킨다. 이 때, 각각의 찾아보기 목록은 해당 펄스신호의 모든 차수에 대하여 그 푸리에 변환을 뼈대공식으로 구하기 위해 필요한 모든 매개변수를 포함하게 된다. 고차원 펄스 신호에 대한 푸리에 변환과정의 복잡성과 계산량등을 비교하여 볼 때, 본 논문에서 제시하는 방법은 기존의 방법에 비하여 대단히 간단하고 계산시간을 단축시킨다. 특별히 몇몇 펄스의 고차 형태는 매우 좁은 폭을 갖게 되는데, 이는 최근 지대한 관심을 불러 일으키고 있는 극초단 펄스의 형태를 근사화 하며, 본 논문에서 제시하는 방법은 이들에 대하여 진가를 발휘한다.

Purpose : Promoting startups has increased in importance in labor market policies since the economic crisis. In Korea, the Ministry of SMEs and Startups is also seeking to revitalize youth startups and traditional markets by moving young stores into idle spaces in traditional markets through 'Project to Support the Activation of Youth Mall'. Research into startups in traditional markets is very limited. Therefore, this study looks at the differences between the management performance of young merchants and senior merchants, and looks at the impact of the business period. Research design, data and methodology : It was divided into youth startup and senior startup based on the age of 40 and startup and nonstartup. Based on these criteria, the company intends to compare and analyze sales and margin rates by setting the sales and margin rates with the management performance of the startup and senior startups. In particular, to look at the feasibility of government funded projects for young merchants, the company will look at the changes in sales and margin rates of young merchants and senior merchants over the period of operation. In this study, the analysis was based on the raw data of the Statistics of traditional market in 2017, and the ANCOVA was used. Results : First of all, the sales volume of stores operated by young merchants, was higher than those operated by senior merchants. Next, the margin ratio does not differ from that of stores that are for young people and those. These findings suggest that the profit structure of stores in traditional markets is similar between young merchants and senior merchants. Third, if you look at the performance of new startups based on one year of business period in more detail, it turns out that young startups have improved in sales and margin rates since startups, while senior startups have no difference. Conclusions : While it means that management performance can be improved through support for young startups, it suggests that there is a limit to supporting senior startups. Therefore, this research indicates that the government support projects centered on youth can contribute to the revitalization of traditional markets.

본 논문에서는 3차원 동영상의 시간적 중복성과 룩업 테이블을 이용한 효과적인 3차원 동영상 홀로그램 생성방법을 제안한다. 기존의 N-LT를 이용한 홀로그램 생성 기법은 미리 생성된 요소 프린지 패턴을 단순 이동 시켜 물체에 대한 홀로그램을 고속으로 생성할 수 있게 하였다. 하지만, 3차원 동영상 홀로그램의 경우는 정지영상에 대한 홀로그램에 비해 방대한 양으로 인하여 실시간 홀로그램을 생성하는데 많은 시간이 필요하게 되어 실직적인 제한이 있었다. 반면 이러한 3차원 동영상은 인접한 프레임은 유사한 정보를 갖는다는 시간적 중복성을 갖고 있고, 이러한 특성을 동영상 압축에 이용하고 있다. 따라서 본 논문에서는 이러한 3차원 동영상의 시간적 중복성을 이용하여 계산하여야 하는 데이터의 양을 현저하게 줄임으로써 3차원 동영상에 대한 홀로그램을 고속으로 생성할 수 있는 새로운 방법을 제안하고 실험을 통하여 검증하였다.

The purpose of this study was to be inquired inner contemplation of the tattoo expressed in the modern costumes. For this study, related documentaries and pictures or photos were analyzed in terms of the theretical background for the history of tattoo, the relation between tattoo and the modern western costumes. The primary source of pictures or photos are Vogue, Collections, Collezioni, Harper\`s Bazaar, Modain, Model et Mode etc. The human\`s needs of body decoration had constantly pursued on the body and costumes from the first until lately. Especially in the recents, as the tattoo is implicated a dynamic and charming method of all kinds of body decoration, it\`s used a motive of modern western costumes. The original tattoo means a picture, word etc. that was put permanently onto their skin using a needle and coloring matter. But, these days tattoo is an expression of street style for something new in the subculture. The results were as a follows : The inner meaning of tattoo represented in the modern costumes was classified into two categories. First, the tattooing was a very important factor to complete fashion design through the history of modern costumes, and also the elaborate tattoo of the body was displayed unrestricted formativeness as the skinhead\`s tattoo, raceless\`s ambiguity of street style and artistic decoration, because that can be faded easily. Second, Tattoo Look was expressed as tattoo prints of the see-through, elastic textiles in the modern costumes. That is, the tattoo enhanced the effect of dramatic atmosphere other formative arts as well as the modern costumes by Tattoo Look. Similarity, Tattoo Look could be interpreted as the change of the aesthetic consciousness by the influence of the subculture. Accordingly, in the end of a this century, many experimental designers had applied tattoo to modern costumes. So this study will stand as an important clue to foresee the future costume\`s style and change.

This research was started to study how the design identity of an overseas fashion house was formed, changed and connected. For the purpose of the study, Saint Laurent House was selected as the subject of the study, because it began as a couture house and launched the $pr\hat{e}t-\grave{a}-porter$ for the first time among the designer brands, and also contributed to the development of modern women's fashion. Literature survey on related books and papers was performed to study the Saint Laurent House. Then, fashion collection photos of the house from 1962 SS to 2014 SS were collected to analyze and compare the features of the designs. The photos were collected from related books, fashion magazines and internet sites. The results are as follows: The features of Yves Saint Laurent's early designs were contemporarily sensational with their couture tradition. His representative designs including Le Smoking, Pea Coat, Loose Fit Blouse, Safari Look, Jumpsuit, Ethnic Look and Art Look became the signature looks of the Saint Laurent House. His designs expressed the liberation of sex, multi-cultural sensitivity and the fusion of art and fashion. His successor, chief designer Tom Ford designed with strong sensitivity of his own. He dealt with Yves Saint Laurent's design themes and signature looks in sensual as well as trendy and sophisticated way. Stefano Pilati showed the Parisienne chic and elegance. He re-made the legacies of Yves Saint Laurent with his own design style using new materials or cutting technique. Hedi Slimane reinterpreted the signature looks of the house with his rock' n roll mood for young, modern women while reflecting the spirit of Yves Saint Laurent's early stage. In conclusion, the design identity of Saint Laurent House is not just a fixed one. By the subsequent chief designers, the signature items and design spirit of Yves Saint Laurent have been succeeded, reintroduced or changed to be trendy and to reflect the designers' design sensitivity. All of these make and maintain the design identity of the fashion house.

Geometrical figures have been used as artwork motifs from the ancient times to the present day. The area of fashion, being a part of modern art, is also largely influenced by geometry and geometrical shapes are being used as a motif for fashion design now more than ever before. However, studies about geometry in the fashion field are not yet done enough and further research is necessary. This research will therefore investigate the usages of round, square and triangular design in contemporary fashion. The main scope of this research is to look at the type of expression and analyze the intrinsic meanings of these shapes in modern fashion. This research will look profoundly into the general characteristics of these geometrical figures and analyze the effects and uniqueness found in the world collection introduced since 2007. As a result from this study, it was found that round and square objects were perceived in such a straightforward and positive way and these designs, when worn, really completed the final look. On the other hand, the triangular design was used mainly for spatial expansion and was interpreted in a more metaphorical, indirect and abstract way. The intrinsic meaning of round, square and triangle figures in contemporary fashion consists of the informal features that really steps out of the formative clothing structure. The topological changes that is formed from the interactive functions and the wholism that creates a new system through integration of the human body and clothing contains the intrinsic meaning of these geometrical figures. Based on the research results, the method of expression and the characteristics of modern day fashion's geometrical figures was able to be easily understood. This work provides the useful information on the development of fashion design and the extended interpretation of clothing structure.
