The existing multiple modulus-based self-recovering equalization type has not been applied to initial equalization. Instead, it was used for steady-state performance improvement. In this paper, for the self-recovering equalization type that considers the multiple modulus as a desired response, the initial convergence performance was improved by extending the dynamics of the errors using error boosting and their characteristics were analyzed. Error boosting in the proposed method was carried out in proportion to a symbol decision for the equalizer output. Furthermore, having the initial convergence capability by extending the dynamics of errors, it showed excellent performance in the initial convergence rate and steady-state error level. In particular, the proposed method can be applied to the entire process of equalization through a single algorithm; the existing methods of switching over or the selection of other operation modes, such as concurrent operating with other algorithms, are not necessary. The usefulness of the proposed method was verified by simulations performed under the channel conditions with multipath propagation and additional noise, and for performance analysis of self-recovering equalization for high-order signal constellations.

The transformation of sector system in Information and Communications Technology (ICT), a prominent character in sector system, has been paid much attention in innovation theory with rapid change in information technologies and technological environment. In this context, we explore how Sectoral Innovation System (SIS) in ICT has been transformed since 1970 by employing US patent data and Proxy variables which measures the basic elements for SIS and its technological characteristics. By utilizing patent data, it is demonstrated that technological regimes, key links and Schumpeterian patterns of innovation in overall ICT sector have drastically transformed over the last three decades. We also reviewed how changes of knowledge bases and technological characteristics driving forces of dynamics in ICT help heterogeneous agents interact with environmental factors (Industrial structure and institutions), leading to industrial or economic growth and its dynamics in the historical perspective over ICT sector (Telecommunication, Computer and Semiconductor). Consequently, our research shows clearly that Schumpeterian patterns of innovation have shifted from Mark I to Mark II in ICT. Our study also provides a glimpse picture of dynamics patent data.

본 연구는 윌리엄 포사이드(William Forsythe)의 "One Flat Thing Reproduced"를 바르테니에프 펀더멘탈(Bartenieff Fundamentals)을 통해 그의 무용수들이 가지는 특징적인 움직임 패턴을 분석하였다. 본 연구 목적은 윌리엄 포사이드의 대표적인 안무적 특징인 역동성, 강인함과 공간적 조화로움을 가능하게 하는 그의 무용수들이 가지는 특징적인 움직임 패턴을 알아보기 위함이다. 연구결과 윌리엄 포사이드는 호흡을 안무의 요소로 사용하였고, 상-하체분리패턴은 포사이드 움직임의 특징적인 요소로 관찰되었으며, 서포트(Support)가 있는 듀엣(Duet) 움직임에서는 신체반쪽연결패턴을 사용하는 것으로 나타났다. 이는 역동성, 강인함과 공간적 조화로움이 깊은 관련이 있을 것으로 보여 진다. 더 많은 사례를 통해 움직임 패턴을 연구한다면 에너지 표현에 직접 적용 가능한 패턴들을 구체적으로 밝혀내어 안무를 하는데 있어 기초자료로 활용될 수 있을 것으로 예상된다.

This purpose of this study was about the analysis on the dynamic expression of geometric manipulation in interior composition elements. The paradigm of contemporary times became different from paradigm of modern times. The change of paradigm is caused by the side effect of paradigm of pre-times. In the contemporary architectural condition, architecture have a tendency to plural characteristics. This study investigates systemically ‘the DYNAMISM’ as a part of contemporary interior space's feature, based on geometric manipulation in interior composition elements. First of all, the dynamic characteristics of architectural space. The second, relationship between the architecture and geometric manipulation.

The aim of this study is to forecast characteristics of dynamic expression in the architecture design by analyzing characteristics and trends in dynamic expressions of the architecture classified by period. The various architectural trends, even in the transition of new paradigm after collapse of the CIAM, consistently expresses dynamics of architecture. In this study, it regards the inherent characteristics of the architecture design as expression of space organization and modelling and it views dynamic expression is important element of the architecture design. The case study shows that the architecture of passed 50 years, the key element of the dynamic expressions are expression of new technology and expression of one's experience. Also, it shows that the dynamic expressions of architecture in 1990's are expression of new technology which consists of lightness, fragmentation, and symbolism that reflects the trend of arts in 1990's.

The purpose of this study was to investigate how different priorities were among entrepreneurial components influencing upon performance of firm regarding dynamics of textile fashion industry. For research method, 200 questionnaires were distributed to professionals such as entrepreneurs, and managers of textile fashion business. The returned 122 questionnaires were analyzed by regression analysis with SPSS 10.0. The results of this study were as follows: There were significant differences that the most influential component was fund among entrepreneurial components affecting performance of firm, and business idea, and entrepreneur's characteristics in a descending order. But when considering dynamics of textile fashion industry, the most influential component was business idea, and entrepreneur's characteristics, and fund in a descending order.

본 연구는 자원의존이론, 거래비용이론, 관계계약이론 등의 선행연구를 검토하여 관계지향성의 원인과 성과를 밝히고자 하였다. 먼저 구매기업과 공급기업간의 행동적 관계지향요인과 관계지향성 분석을 실시하였다. 행동적 관계지향요인으로는 정보교환, 조화노력, 행동적 규범, 업무결속을 들고, 관계지향성 분석을 위해 군집분석을 실시하였다. 연구표본에는 C지역의 전문건설업체를 대상으로 500부의 설문지를 배포, 그 중 185부를 회수하여, 적합한 설문 140부가 사용되었다. 군집분석결과 관계지향성 집단은 정보교환, 조화 노력, 협동규범 수용, 업무결속이 모두 높게 나타났고, 비관계지향성 집단은 정보교환, 조화노력, 협동규범 수용, 업무결속이 모두 낮게 나타나 기업간의 관계지향성을 의미있는 2개의 집단으로 나눌 수 있었다. 둘째, 기업간 관계지향성의 영향요인으로 환경의 역동성, 대안의 이용가능성, 공급의 중요성, 상호호혜전략, 신뢰성을 검토하였다. 본 연구에서 선정한 관계지향성에 대한 영향요인들이 관계지향집단과 비관계지향집단으로 분류하는데 얼마나 유용하게 이용될 수 있는가를 알아보기 위해 판별분석을 실시하였다. 관계지향집단과 비관계지향집단의 분류에 환경의 역동성, 대안의 이용가능성, 공급의 중요성은 영향이 없는 것으로 나타났으며, 호혜전략, 신뢰성은 의미가 있는 것으로 나타났다. 셋째, 기업간 관계지향성의 성과로서 실현경쟁우위와 관계유지의도를 검토하였다. 관계지향성이 성과에 어떠한 영향을 미치는가를 검증하기 위해 MANOVA(multivariatee analysis of variance)분석을 실시하였다. 실증 결과, 관계 정도가 높은 집단이 관계 정도가 낮은 집단보다 실현 경쟁우위수준을 높게 지각하고 관계를 유지하려는 의도가 높은 것으로 나타났다.
