Architecture should deviate from euclidean ideas of abstract space while helping to accommodate individual perceptions and experiences of a given space. Concepts for making space should be cognitively processed. The process of gathering information from the environment represents a new spatial concept as expressed in the cognitive structural relationship between the environment and the individual as the subject of architecture. Additionally, the cognitive experience of space is primarily perceived visually, and visual perception is the basis for information-gathering and decision-making. Therefore architecture should be excluded from the conceptual focus on the existing space design rules, being expressed instead in experimental architectural spaces connected to subjective human experience. While some research has been done on this topic regarding architecture, further study is required in the area of interior design. This study proposes the possibility of composing effective living space through an investigation of cognitive space concept theory and expression elements, and includes a case study of Interior architectural spatial analysis.

Recently, for safety of people, there are proposed so many technologies which detect density of people at the specific place or space. The representative technology for crowd density estimation was using image analysis method from CCTV images. However, this method had a weakness which could not be used and which's accuracy was lower at the dark or smog space. Therefore, in this paper, to solve this problem, we proposed a user density estimation system at closed space using high frequency and smart device. The system send inaudible high frequencies to smart devices and it count the smart devices which detect the high frequencies on the space. We tested real-time user density with the proposed system and ten smart devices to evaluate performance. According to the testing results, we confirmed that the proposed system's accuracy was 95% and it was very useful. Thus, because the proposed system could estimate about user density at specific space exactly, it could be useful technology for safety of people and measurement of space use state at indoor space.

최근 실내 공간 내에서의 위치 정보를 이용한 공간정보 서비스가 실외공간에서 제공되는 서 비스만큼 공간정보시스템의 중요한 응용분야로 자리 잡고 있다. 실외 공간과 달리, 실내 공간의 위치 정보는 좌표기반이 아닌, 방 번호와 같은 기호를 기반으로 표현된다. 따라서 실내공간에서 이동객체의 위치를 추적하기 위해서는 이동객체의 현재 위치를 이용하여 좌표정보를 예측하는 것이 아니라, 기호적 추론이 필요하다. 이에 본 논문에서는 RFID센서를 이용하여 이동객체의 위치를 항상 명시적으로 결정할 수 있는 추적가능 실내 기호공간을 위한 프레임웍을 제안한다. 우선, 실내기호공간과 실내기호공간에서의 위치추적에 대한 개념을 소개하고, 추적 가능한 실내 기호공간을 위한 접근성 그래프를 정의한다. 둘째로, RFID 리더기의 배치방법, 추적 가능한 실내기호공간을 위한 접근성 그래프 생성방법과 이를 이용한 위치 추적방법을 제시한다. 마지막으로, 제시한 방법의 유효성을 보이기 위하여 실험결과를 보인다.

Increased internet use under a ubiquitous environment may be called as a great human information space revolution followed by Industrial Revolution. This revolution is exerting its significant influence over all the industry as a whole with speed faster than that of any other times. Along with this trend, if furniture design field that leads living culture should fail to jump on this main stream without noticing it, it may be reduced to a unpopular field some day without any sign of recovery. Under this background, this study is intended to recognize a goal aiming at understanding our rapidly changing living environment and leading our way positively. Currently, our surrounding living environment is immersed in computers here and there and Mark Weiser once defined a system that moves in advance before an action as ubiquitous computing and in this respect, I am going to observe a detailed transformation process of space. First nature of the space may be defined as atoms, a physical space equivalent to a spatial element and Bits space that is untouchable is usually called as 2nd space and a combination of atoms and Bits is an intelligent space - 3rd space - that can be intelligible without touching it and finally, this space is called as a ubiquitous space. This spatial transformation is developed by several changes of living environment and we may call it as living trend or interior design trend. Transformation in terms of social perspective, space structural perspective and digital technique perspective may be enumerated. These transformations were surveyed based on its contents being implemented at a future housing exhibition hosted by 5 construction companies along with fusion of information furniture and furniture depending on each housing space. In conclusion, it could be realized that most of the companies were decorating future space by implementing ubiquitous environment as a success factor of future housing market. It may be meaningful to note once again that under an interior environment, a fusion of furniture and information furniture is required considering interior trend elements.

This article investigates the distributed data storage problem in the space information network (SIN) using distributed fountain codes. Since space nodes in the SIN are resource-limited, in order to reduce energy consumption while improving the storage reliability, an efficient distributed storage based on fountain codes and probabilistic broadcasting (DSFPB) strategy is proposed. In the proposed strategy, source packets are disseminated among the entire network according to probabilistic broadcasting (PBcast), and the final degree distribution is close to the desired robust soliton distribution (RSD), this is benefited from the appropriate packets encoding procedure of the proposed strategy. As presented by the analysis and simulations, the total cost of data dissemination is greatly reduced compared with existing representative strategies, while improving the decoding performance.
