The structural optimization has been carried out in the continuous design space or in the discrete design space. Generally, available designs are discrete in design practice. But methods for discrete variables are extremely expensive in computational cost. In order to overcome this weakness, an iterative optimization algorithm was proposed for design in the discrete space, which is called as a sequential algorithm using orthogonal arrays (SOA). We focus to verify the fact that the local solution can be obtained throughout the optimization with this algorithm. The local solution is defined in discrete design space. Then the search space, which is the set of candidate values of each design variables formed by the neighborhood of current design point, is defined. It is verified that a local solution can be founded by moving sequentially the search space. The SOA algorithm has been applied to problems such as truss type structures. Then it is confirmed that a local solution can be obtained using the SOA algorithm

The paper begins with the idea of the society of the continued rooms that building connects architectural space (building interior) and urban open space (urban interior) or countryside/rural open space (territorial interior). It gives an account of, through literature review, a theoretical possibility of integrating not only architecture and urbanism but also architecture and countryside/rural planning. The first site explores the continuously articulated and connected spaces between building interior, urban interior, and territorial interior, in understanding Alberti's analogy, "A house is a little city." (1452) The second site illustrates architecture as an open boundary and a spatial medium which makes building, urban, and territorial interiors connect and makes them continuous. There is an opportunity of reading the continued relations and the continua of spaces. The third site deals with the form of building that architecture creates for building interior (society of rooms) and urban interior (society of urban rooms), and moderates the interiors. The last site clarifies the territorial interior (society of countryside/rural rooms) that constitutes homogeneous spatiality moderated by architecture between building interior and urban interior. The paper discusses the society of the continued interiors(building/urban/territorial interiors) that ought to be a fundamental truth in the field of every project which deals with a unit of space. It logically clarifies the society of the interiors, not isolated and blocked off but multilayered and continued. It comes to the conclusion that the territorial interior should be subsumed under the design field and the society of the continued rooms ought to be considered as a united object of space in the fields of interior architecture/design, architecture, landscape, urbanism and countryside/rural planning. Ultimately, it aims at offering a departing point of discourse and a theoretical foundation for the future studies on urban interior and territorial interior.

The purpose of this study is to analyze the meanings and expressional characteristics of space-time concept in modern architecture. As the architecture spaces reflect and represent the characteristics of times, the meaning and modern expression of space-time concept was studied in the developmental process of space concept on the base of the background of philosophy, science and psychology. At the late 19th century, space concept was changed with relative time-space in philosophy and science and the theory of visual perception. In the beginning of 20th century, space-time concept that combined space with time in the process of image open space expanded movement was developed. In modern architecture, it was expressed as the freedom of movement by open space expanded infinitely and/or abstract space without spacial measure, multiple view point by superimposed and/or polyhedric space and kinetic vision by dynamic and/or continuous space.

Light creates ambiance that affects our impression of space. Before the modern age, the role of light is a religious factor and a primitive state to see. In the modern space design, light is used to achieve the continuous transformation and translation of building's image. Ever-changing space is a flexible corresponding of space to its environment, caused by certain dynamic light. The space turn into some other thing from what it was before, or just changing its character. approaching men and society with different meanings. The purpose of this study is to explore the relation between light(natural and artificial) and ever-changing space through the case study. The impacts of light on ever-changing in today's space design can be summarized as follows. 1) Materialization of light in space design. Nowadays light becomes a form itself. The geometric properties of the space form playa secondary role as compared to the importance assigned to light. 2) Pixelization of space by a light effect. The impacts of digital technology on the space design have come through enhancing the 'pixelization' of the surface from which buildings are made their responsiveness and adaptability to changing needs. The surface with ever-changing lights that blur the boundary of space and expand the image of space.

The purpose of this study is to propose cognitive ecological effects of fractal patterns in space design. This study investigated the perception and cognition problems regarding landscape patterns showing fractal properties from the cognitive perspective instead of the traditional speculative approach. In particular, the researcher has verified that fractal geometry theory and fractal pattern concept provide insight in space aesthetic values and cognitive effects. Research results are as follows. First, most environmentally-friendly fractal urban forms provide cognitive connectivity. In particular, this space provides a positive emotional response and preference to humans and displays self-organized complexity. This study found that such complexity of space form has characteristics corresponding to parallel cognitive structures of the human brain. Simultaneously, the researcher suggests that the fractal landscape pattern is an alternative for stiff and homogenized modern space. Second, fractal patterns provide hierarchical connectivity within the brain through continuous difference and repetition. In particular, self-similarities of fractal patterns administer significant visual grouping and coherence in human perception. It can be determined whether scaling coherence facilitates easier organization in cognitive organization. Third, fractal patterns in space design provide the basic method for achieving the connection between concept, construction, and urban factors. As a result, the researcher has suggested that scale distribution of geometrical factors, such as fractal patterns, an be a design method to connect various space typologies.

The structural optimization have been carried out in the continuous design space or in the discrete design space. Methods fur discrete variables such as genetic algorithms , are extremely expensive in computational cost. In this research, an iterative optimization algorithm using orthogonal arrays is developed for design in discrete space. An orthogonal array is selected on a discrete des inn space and levels are selected from candidate values. Matrix experiments with the orthogonal array are conducted. New results of matrix experiments are obtained with penalty functions leer constraints. A new design is determined from analysis of means(ANOM). An orthogonal array is defined around the new values and matrix experiments are conducted. The final optimum design is found from iterative process. The suggested algorithm has been applied to various problems such as truss and frame type structures. The results are compared with those from a genetic algorithm and discussed.

본 논문에서는 운동량 바이어스 안정화된 인공위성의 능동 미동 제동율 위한 자동 제어기의 설계에 새로운 연속의 스위칭 방정식율 도입한 가변구조 시스댐 이론을 사용하였다. 일반적으로 미동 제동을 갖고 있는 션형화된 다변수 시스템에 가변구조 이론을 적용할 때, 스위칭 이득을 어떻게 결정해야 하는지, 진동 현상과 입력과 상태 궤적에 도달기간을 어떻게 줄여야 하는지 등의 단점을 갖고 있다. 이러한 문제를 해결하기 위해서 본 논문에셔는 슬라이딩 모드를 얻기 위한 불연속의 스위칭 로직 대신에 연속의 스위칭 방정식을 제시하였다. 이 새로운 접근방법은 기존의 가변구조 이론에 의한 방법보다 훨씬 간단하고, 구해진 제어입력이 연속이므로 진동현상이 없으며, 동시에 설계인자를 적절하게 선정하므로써 도달기간을 줄일 수 있게 된다.

When we make a place for people, interior space and exterior space are always connected, each influencing the other. To create a better space or increase the quality of an existing space, it is essential to look at the relationship of inside and outside and their boundaries. Without consideration of the landscape, the building itself gives only limited satisfaction to people. This is an important issue for anyone who deals with space. This study intends to explain the important need for a change in attitude towards our built environment and its intrinsic relationship with its natural context. In the study, I try to find design concepts for integration of inside and outside which have accumulated since early Modernism designers and consider cases with different solutions and approaches that make total design sense when looking at the inside and outside as a whole, then, through observation of the cases, I find 5 design methods(Opening, Continuing, Insulting, Wrapping, Interpreting) in connecting the two spaces and analyze the solutions. The various examples which are shown in each patterns will help us to find ideas for the best solutions of integration of inside and outside. It is true that the idea of integration of inside and outside will increase the quality of our environment and it comes with the current thoughts of ecological and sustainable design. Thereby, I suggest designers to change their manner to continuous and integrated point of view in dealing with built environment.

New simplicity means essential concept that is continuous rather than being concept that do not overcome formal, material functional boundary. Consuming masses, decorative reactionism is possible in infinite resource and continuous plenty. Nowaday situation can not forecast the affirmative future bases on economic performance and practicality, so simplicity esthetics which consisted of minimum things is justified. The purpose of this study is to discuss not the formal and functional simplicity but new simplicity to express the essential thoughts and emotional contents of human life.

The architectural space is the involuntary place where man lives and experiences, and as a 3 dimensional space through the continuous experience with the concept of 4th dimension of time, it provides the observers with the dramatic space imagery. These kinds of space experiences are experienced mentally and perceptively through the physical elements of inner and outer space of the architectural buildings, and this space imagery is created here by all the space composing elemensts of the building. These space experiences are caused by the changing processes of the space characteristics, and the observers perceive the changes in space characteristics. The present building is going with Eco-Architecture. When 2008 sees the building,,Eco-Architecture design which hits appears. There is a possibility of seeing 16 kind types from that place. And From here examined the spatiality which is expressed. These changing processes of inner and outer space, space versus space, and unit space, which are perceived by the observer. It`s way to help in architectural design and wishes.
