This research analyzed the space scheme in connection with complexity, one of the new changes in the discount stores, and has a goal of predicting the direction of space scheme in the upcoming complexity era. The research was conducted in the following way. Firstly, this researcher tried to grasp what kinds of changes were required in the overall distribution industry socially and economically. Secondly, the characteristic and situation of discount stores were scrutinized. Thirdly, the domestic stores' complexity status was classified and types of those were elicited. Fourthly, the time-series change and use were analyzed. The result of this analysis reveals that the types of complexity can be divided by location and adjustment to environmental changes. The time-series analysis shows that total operating area, the number of parked cars and the tenant ratio have increased dramatically in 2000 and 2003. And, according to the correlation analysis between factors, the tenant ratio has, a strong correlation with other two factors. Self-complexity takes the basic form of living facilities and complexity with other facilities is combined with other cultural, sales, educational and administrative ones. Mass-complexity is merged with the stadiums, parks or station sites. As you've seen, the concept of complex shopping mall for the realization of one stop shopping and convenience will continue in the days to come. It is desirable that the study on the large-scale shopping spaces will be conducted continually for the preparedness of future life style.

Mass customization is a marketing strategy to meet consumer needs for variation and uniqueness of products. Although there are quite a few studies quantitatively investigated the options provided by mass customization process, scholarly work related to mass customization has provided mixed results on consumer perception of complexity and their responses. The purpose of the study is to derive the factors that influence consumer complexity perception in online apparel mass customization process and consumers' needs to enhance mass customization services. Data were collected by conducting focus group interviews of which 29 participations in 4 groups. The results of the study suggested that consumers perceived complexity through mass customization process due to too many choice options. However, the effect of number of options on respondents' complexity perception was different depending on consumer characteristics such as consumer expertise and fashion involvement, and the characteristics of consumer preference development. Shopping context such as shopping purpose is another moderating factor. This study also suggests that a variety of marketing strategies which can enhance mass customization services affect the relationship between the number of options and consumers' complexity perception. The findings of the study provide academic and managerial implications.

Naval ship design and related other activities can be characterized by the complexity of the interactions among products, activities, and disciplines. Such complexities often result in inferior designs, cost overrun, and late-delivery. Hence there exist tremendous interests in both improving the design process itself and optimizing the interactions among design activities. This paper looks at the complexity of designing naval ships thereby leading to the innovation of current ship design practices using design structure matrix. It can be used to induce the optimal ordering of design activities as well as identify sources of complexities. The method presented here identifies coupled design activities useful for reducing the complexity of naval ship design as well as optimally reordering design activities. This paper recommends the use of design structure matrix method suitable for numerically optimizing the concept design process of naval ship, and reducing cost and time required in designing naval ships by modeling and analyzing the design activities and engineering tasks, defined in systems engineering planning documents.

The research is a correlational study to look for causes and factors relating to the design of written documents (professional reading materials) and identify those relationships that are useful for communication designers. The research specifically targeted the relationships between perception and reader's past experiences and appearance of the written documents. A preliminary survey, such as interviews, discussions, questionnaires and brainstorming sessions are conducted to establish the observable attributes related to perception which are reader's interests, importance of information and written documents complexity. Finally, the research used Structural Equation Model (SEM) to identify significant differences and analyze strong and weak correlations between these attributes. In general, the results of the study shows that the attribute appearances of a written documents with excellent visualizations for information display shows a strong correlation with interests while the attributes importance is weakly correlated with the complexity of the documents.

본 논문에서는 CSD 계수로 표현되는 FIR 필터를 설계하는 방법에 관하여 고찰한다. 먼저, 게이트 수 측면에서 필터의 복잡도를 추정하는 방법을 제시한다. 이 방법을 통하여 최소의 복잡도를 가지면서 요구되는 성능을 만족시키는 필터를 설계할 수 있다. 다음으로 BonsaiG이라는 MILP 프로그램에 근거한 CSD 필터 설계 프로그램을 제시한다. 2가지 예제를 통해 설계된 필터의 게이트 수가 400-600 정도 차이를 나타내고, 이러한 비교를 통해 최적의 필터를 얻을 수 있음을 보인다.

자산의 복잡성을 측정하기 위해 프로그램의 논리적인 복잡도의 측정을 제공하는 척도를 베이스로 하여 각 자산의 특징 값을 표현하고 있는지 평가하는 방법을 사용 한다. 본 연구에서는 소프트웨어 컴포넌트를 기본자산으로 구성하여 표준화된 설계모형을 확보하고, 이를 기반으로 재사용 가능한 확장된 자산을 설계할 경우 자산의 복잡도를 측정하기 위한 방안을 제시하고자 한다. 그러나 우리가 제안하는 자산관리 시스템의 각 자산은 두 가지 영역의 자산을 합성한 복합자산으로 구성되어 있으므로 이 방법만으로는 정확한 측정을 하기 어렵다. 따라서 아키텍처 하부에 저장된 기본 자산의 특성 값을 반영하여야 전체적인 자산의 복잡성을 측정가능하다. 따라서 응집력에 반비례하고 자산연관도안의 각 자산에 대한 연관값의 누적합에 비례하는 합성자산의 복잡성을 측정 가능하다.

상태 궤환 제어기 설계에 있어서 상태 정보에 대한 접근의 제한성 때문에, 출력 궤환 제어기 설계에 대한 많은 연구가 수행되어 왔다. 그럼에도 불구하고 최적의 출력 궤한 제어기 설계는 여전히 풀리지 않은 문제로 남아 있다. 따라서, 기존에 수행되었던 관련한 다양한 고정형 출력 궤한 제어기 설계 연구 결과를 리뷰하고 복잡도와 안정성 관점에서 성능을 평가 비교함으로써 이 분야의 연구의 방향을 찾고자 한다. 또한, 기존 연구에서 제한적인 시스템 구성에서 제시되었던 알고리즘들을 어떤 시스템 구성에서도 적용가능할 수 있도록 리뷰하는 알고리즘을 완벽하게 제공한다. 리뷰하는 알고리즘은 모의 실험을 통해서 안정성 성능과 연산 시간으로 측정된 복잡도를 통하여 비교 평가한다. 모의실험 결과에 따르면, 대수에 의한 제어기 설계 알고리즘[20]이 가장 적은 복잡도를 가지는 반면에 스케링 변환 기반의 선형 행렬 부등식 알고리즘[18]이 대부분의 경우에 고복잡도를 가지고 가장 좋은 성능을 갖음을 확인하였다.

Euler and Navier-Stokes flow analyses for helicopter rotor in hover were performed as low and high fidelity analysis models respectively for the future multidisciplinary design optimization(MDO). These design-oriented analyses possess several attributes such as variable complexity, sensitivity-computation capability and modularity which analysis models involved in MDO are recommended to provide with. To realize PC-based analyses for both fidelity models, reduction of flow domain was made by appling farfield boundary condition based on 3-dimensional point sink with simple momentum theory and also periodic boundary condition in the azimuthal direction. Correlations of thrust, torque and their sensitivities between low and high complexity models were tried to evaluate the applicability of these analysis models in MDO process. It was found that the low-fidelity Euler analysis model predicted inaccurate sensitivity derivatives at relatively high angle of attack.

To develop in the long view, based on context of city, the spatial program change to new spatial program that can be adopt city architectural environment. The new spatial program must have paring lot, open space, community center, which are infra structure for citizen. The needs about flexible space Increase according to complexity of spatial program. The space of absolutism, is made up hierarchy, can't accommodate complexity of spatial program. Therefore, modern architectural spaces are characterized by non-hierarchy. This research is tendency to search special quality of space program that is going complex composition according to change of modern society and modern architecture space, and analyze characteristic of inner space that have non-hierarchy to correspond hereupon.
