Post-modern society leads us to accept diversity and variability instead of pursuit of the absolute truth, beauty or classical value systems, thus leading to hybrid phenomena. The purpose of this study is to analyze characteristics and expressive effects of hybrid expressions through which to provide conceptual bases for interpreting expanded meanings of fashion illustrations that express aesthetic concepts of hybrid culture. Hybrid refers to a condition on which diverse elements are mixed with each other, so any one element can not dominate others. It is often used to create something unique and new by a combination of unprecedented things. Hybrid can be classified into four categories: temporal hybrid, spatial hybrid, morphological hybrid and hybrid of different genres. Temporal hybrid from a combination of past and present in fashion illustration includes temporal blending by repetition and juxtaposition. Spatial hybrid shows itself in the form of inter-penetration and interrelationship by means of projection, overlapping, juxtaposition and multiple space. Morphological hybrid expresses itself through combination of heterogenous forms and restructuring of deformed forms. Hybrid of different genres in fashion illustration applies various graphic elements or photos within the space, and represents blending of arts and daily living. Such hybrid expressions in fashion illustrations reflect the phenomena of diversity and variability of post-modern society. Hybrid expressions in fashion illustrations predict endless possibility of expressing new images through combining various forms or casual elements and can develop toward a new creative technique.

In this study, a space-time transmission scheme is proposed to tackle the limitations of channel estimation with orthogonal pilot information in colocated multiple-input multiple-output systems with several transmitting and receiving antennas. Channel information is obtained using orthogonal pilots. Channel estimation introduces pilot heads required to estimate a channel. This leads to bandwidth insufficiency. As a result, trade-offs exist between the number of pilots required to estimate a channel versus spectral efficiency. The detection of data symbols is performed using the maximum likelihood decoding method as it provides a consistent approach to parameter estimation problems. The moment-generating function of the instantaneous signal-to-noise ratio is used to drive an approximate expression of the symbol error rate for the proposed scheme. Furthermore, the order of diversity is less by one than the number of receiver antennas used in the proposed scheme. The effect of the length of a pilot sequence on the proposed scheme's performance is also investigated.

강원도 지역의 문화예술 콘텐츠 공간의 활성화는 새로운 전기를 맞이하여야 하며 이는 대내외적 변화에 상응하는 새로운 전략적 접근을 필요로 하고 있음을 말한다. 기존의 천혜의 환경적 속성을 바탕으로 하여 전략과 더불어 지속 가능 모델로 자리매김을 하여야만 한다. 그러나 작금의 경제적 불황과 기후 변화의 영향은 성공적인 문화예술 콘텐츠 공간을 구축함에 있어서 더 이상의 선택적 요소가 아니다. 또한 문화예술 콘텐츠 공간의 활성화를 통하여 지역 경제와 사회문화적 파급력을 집성하려면 공간의 다양성과 구체적인 교육 프로그램도 절대적으로 병행하여야만 한다. 지리적 불리함에도 불구하고 영월은 많은 문화예술콘텐츠 공간들을 이미 갖추었고 다른 지역과 다르게 발전적 전략구성을 집행하고 있다. 문화예술 콘텐츠 공간의 중요성을 산업적으로 활용하는 점에서 고무적으로 판단되어지며 본인은 연구의 범위를 영월로 한정하였다. 따라서 영월 지역의 문화예술 콘텐츠 공간을 진단하고 발전을 위한 모델을 연구하고자 한다. 이는 구체적으로 영월지역 뿐만 아니라 기타 지역의 경제적 고용창출과 소득증대, 사회 문화적 영향력을 창출할 것이며 나아가 지역 문화의 현대화와 이미지 개선, 전반적인 삶의 질 향상 등을 형성할 수 있다고 판단되어진다. 방법적으로 세계화를 지향함과 동시에 지역의 문화 예술적 토대를 근거로 하여 영월의 '지붕없는 박물관도시, 영월' 프로젝트 방향을 세방화 패러다임으로 전환해야 한다. 즉 거시적인 세계화 지향의 발전 모델을 수립하기 이전에 지역의 문화예술 콘텐츠 수요를 파악하고 이를 특화한 시스템과 프로그램을 구축하여야 한다. 왜냐하면 영월지역의 문화예술 콘텐츠 공간은 도 시민에게 삶의 장소로서 직결되기 때문이다.

본 논문에서는 공간-주파수 OFDM (SF-OFDM) 전송 다이버시티 기법을 위한 효율적인 심볼 검출 알고리즘이 제안되었다. SF-OFDM 전송 다이버시티 기법에서 부반송파의 수가 적은 경우 부채널간 간섭이 발생하게 되며, 이러한 간섭은 다이버시티 시스템의 성능을 크게 저하시킨다. 제안된 알고리즘은 부채널간 간섭을 병렬 혹은 순차적으로 제거함으로써 기존 알고리즘에 비해 큰 성능 이득을 얻는다. 컴퓨터 모의실험을 통한 비트오류율 (BER) 성능 평가 결과. 두개의 송수신 안테나를 사용하는 경우, $10^{-4}$의 BER에서 약 3 dB의 성능 이득을 얻을 수 있음을 확인하였다. 제안된 알고리즘이 적용된 심볼 검출기는 하드웨어 설계 언어를 통해 설계되었고, $0.18{\mu}m$ 1.8V CMOS 표준 셀 라이브러리를 이용하여 합성되었다. 제시된 하드웨어 구조와 함께 설계된 SF-OFDM-PIC 심볼 검출기는 약 140K개의 논리 게이트로 구성되었고, SF-OFDM-SIC 검출기는 129K개의 논리 게이트로 합성되었다.

This paper presents a structure of the searcher using the space diversity in array antenna system operating in the DS/CDMA signal environments. The new technique exploits the fact that the In-phase and Quadrature components of interferers can respectively be viewed as independent Gaussian noise at each antenna element in most practical CDMA (Code Division Multiple Access) signal environments. The proposed PN acquisition scheme is a single dwell serial PN acquisition system consisting of two stage, that is, the searching stage and the verification stage. The searching stage correlates the received signals with the local PN oscilator for obtaining the synchronous energy at the entire uncertainty region. The verification stage compares the searching energy with the optimal threshold, which is pre-designed in the Lock-Detector, and decides whether the acquisition is successful or fail. In this paper, we analyzed the relationship of both diversity order and the mean acquisition time. In general, It is known that the mean acquisition time decreases significantly as the number of antenna elements increases. But, the enhancement of the performance is saturated in terms of PN acquisition scheme. Therefore, to decrease the mean acquisition time, we must design the optimal array antenna system by considering the operating SNR range of the receiver, the detection probability, and the false alarm probability. The performance of the proposed acquisition scheme is analyzed in frequency-selective Rayleigh fading channels. In this paper, the effect of the number of antenna elements on acquisition scheme is considered in terms of the detection probability, false alarm probability. and the mean acquisition time.

There are many ways to know the social and cultural level of each country. Among them, a theme museum are not only the best place to understand the history, the life style and the culture level. This thesis has the purpose to provide the basic material through analyzing the space composition and the visitor circulation of the theme museum and understanding the relativity of them so that the new theme museums can be designed in the right direction. So I chose the independence museum that opened with in recent 10 years, finally middle & small size's theme museum were selected. The results from the case study are as follow. Firstly, according to a result of analyzing the characteristics of space composition with the ratio of each part's area, space composition of each museum is mainly for the exhibition part, but rarely for the education part. Secondly, theme museums in Jeju have the limit of diversity of circulation method because they have not the free circulation method. Thirdly, the characteristics of space composition is divided into basic type, center-hall enter type, around the center-hall type and guidance type. Fourthly, by analyzing the characteristics of space composition and circulation method of traffic line, it's realized that selective circulation method was applied to basic type and center-hall enter type, and guidance circulation method was applied to around the center-hall type and guidance type.

Discussions on transparency have been being analyzed as variedly as the diversity itself in contemporary architecture. Though it is inappropriate to summarize the discussions into several specific viewpoints, as the notional classifications on transparency are varied according to the points of individual researchers, it can be said that, by approaching with the standpoint of the designers who may have various difficulties in the course of design, the meaning of this thesis lies largely in the fact that it attempted to study the architectural application techniques of transparency notion both through surface aspect which could be said to decide on the appearance of the architecture shape and through, in physical aspects as a combination of space components comprising the inner space, spatial aspect to which architectural techniques of transparency notion are applied. Through these, we conclude as follows. 1. Representation Techniques of Transparency in Surface : Transparency from surface viewpoint could be categorized into 1) emphasis on property-of-matter, 2) lightness of Literal material itself, 3) visual ambivalence, and 4) dematerialized hyper-surface. 2. Representation Techniques of Transparency in Space : In spatial viewpoint, transparency is summarized into sub-viewpoints as 1) straightforward space 2) ambiguous spacer 3) expanded space

The modern society is rapidly changing through the development of computer network technology. By generation a collapse of boundaries between may important social institutions, computer networking has affected culture, economy and the physical environment. Because of this, people face a switchover from a simple society, to a compound society. It will also increase the diversity if society's demand, though, and experience. This change is not an exception in the exhibition space. People are more interested in civilized pastimes and also demand diverse thinking. So as a necessary consequence, the function of museum space Is offended and that there are various attempt to increase information and demand of that space. The purpose of this study is try to find a solution a countermeasure of modern society's mobile situation. Researchers analyzed structural qualities of Hyper-text; non-boundary, interaction and nonlinear and deduce nine kinds of methods to apply in space. Also, Researchers looked at the examples in museum space and derived like this expression way; dynamics, mobility, a non-materiality, continuity, complexity from analysis of expression way.
