Since the significance of the living room has been stressed as the space for family gathering, the weight of an ornamental console among the living room furniture is being increased. A console is an excellent small-sized furniture to highlight the spatial characteristics by being placed in front of the plane wall, which is left as an empty space or between doors. Therefore, this study aims to defined a console and to understand the issues raised on it by analyzing the domestic and international data that are addressed until today. Meanwhile, various consoles in the market today were analyzed through catalogues, data derived from internet, and literature sources on furniture to conduct the processes of idea sketch, rendering, design confirmation, design draft, and computer rendering (3D). As for the design concept of a console, modern design equipped with practicability and ornamental is adopted in the form of a combined console table and flower vase. In terms of economic feasibility and versatility, the design is developed to allow the console use by removing the glass pipe depending on needs and in case of using a flower vase, small flower can be decorated using a glass pipe for the ornamental effect.

Design sketch of electrical power system, mass, and cost of a new satellite is an inevitable step preceding the full-scale development of the satellite. In this paper, major features of recently developed conceptual design tools of satellites are investigated. And, based on the surveying results, we summarize the conceptual design procedure of satellites. The required electrical power to support the operation of the payload mission determines the size of solar panel and battery. The mass of the integrated system and subsystems is then estimated based on the database of the previously developed satellites. Cost can also be roughly estimated using the database without consideration of complex calculations.

This paper presents an effective and robust leaf image retrieval system based on shape feature. Specifically, we propose an improved MPP algorithm for more effective representation of leaf images and show a new dynamic matching algorithm that basically revises the Nearest Neighbor search to reduce the matching time. In particular, both leaf shape and leaf arrangement can be sketched in the query for better accuracy and efficiency. In the experiment, we compare our proposed method with other methods including Centroid Contour Distance(CCD), Fourier Descriptor, Curvature Scale Space Descriptor(CSSD), Moment Invariants, and MPP. Experimental results on one thousand leaf images show that our approach achieves a better performance than other methods.

The purpose of this study is to suggest methods for the community design through users' behavior study in apartment housing. This study was approached by using both theoretical investigation and empirical research. The theoretical investigation actualized the concept of community design in apartment housing through a literature survey. The empirical survey focused on seeking out a user-oriented design criteria based on the analysis of residents' usage behavior and mental map. The results of this study are as follow: First. regarding the analysis of the residents' attitude toward the share community space(SCS), it was found that the SCS made a sense as community facilities in apartment housing. Second, regarding the SCS through the metal map, it was shown that the sketch map analysis was a useful research method for the community design by actualizing the residents' behavior characteristics. Third. as to the results of analyzing the metal map, it was found that the considered characteristics in recognition of the SCS were related to the liking with the main paths, cross nodes of the moving line, the location of center. and the complexity. In conclusion, the SCS is the main of community design in apartment housing and the above characteristics in recognition are useful as the guidelines in the SCS planning.

Contemporary society is lately going through various changes in social, economic, and cultural aspects due to rapid growth of information and computer technology. The digital revolution generated from the development of network reflects the decentralizing characteristic that connects local and personal interconnections. The following paper is designed to develop a basic understanding of digital architecture and show that digital virtual reality is not accidental phenomenon but it is actually evolved from nature and recreated in cyber space. The relationship between nature and digital architecture will be explained through the background research of how digital architecture was born and how it has been transformed. Also, it is designed to find out modern trends of digital architecture through diagrams and virtual space of hyper architecture and follow up the new phenomena appearing in the field of architecture. It is said that digital architecture is a new trend of architecture created from computer bit but all architecture that has form and shape cannot be independent of nature. Nature is the root of everything and even mechanical abstraction such as 'digital' can find its form in the immanence melted in the pure essence of nature. The research found that the nature approach of digital architecture also needs no more than 5 sequential references to find its genuine sketch as the hypertext theory shows we need only 5 sequential references to prove we are all related. Additionally, the cyber space that is become a general living space and a indispensable factor of digital architecture is a space that has obscurity and more open culture. It represents the characteristics of contemporaries in various aspects of society.

With the rapid progress of location based services, GIS, and ubiquitous computing technologies, the space that we are dealing with is no longer limited to outdoor space but being extended to indoor space. Indoor space has some differences from outdoor space, therefore to provide integrated spaces and seamless services, it is required to establish new theories, data models, and systems. For this reason, ambitious project has been launched last year to establish a theoretical background, develop a core technologies and systems, and provide services of indoor spatial awareness. In this paper, we present an overall sketch on the project and major research topics. First, we present the ISA (indoor spatial awareness) project with its goal and research topics. Second, a simplified 3D spatial model, called prism model, is proposed as a basic data types and operators of indoor spatial DBMS. Third, a indoor feature data model, developed T. Kolbe et al. who is a member of this project team, is introduced in this paper. This model provides a basis for the integration of different spaces.

The Cosmic Microwave Background (CMB) contains a wealth of information about the perturbations in the early universe. Its bispectrum, the Fourier counterpart of three-point correlation functions, is a direct probe of primordial non-Gaussianity predicted by many physically well motivated inflation models. Motivated by the substantial improvement in sensitivity expected from future CMB surveys, we developed a novel bispectrum estimator capable of handling such high-resolution data. Our code, named CMB-BEst, utilises a set of separable basis functions to constrain a wide variety of models simultaneously. Flexibility in the choice of basis enables targeted analysis on highly oscillatory inflation models, which are previously unconstrained due to the numerical and computational challenges involved. We present the results of our thorough validation tests, both internal and against conventional approaches. We provide a proof-of-concept example with Planck satellite data and sketch out the road ahead.

The purpose of this study is to understand the present status of life style and housing demands of residents in Yoing-in and Kwang-Ju in Kyung-Ki province, Korea. Field study methods were carried out practically using participant observation method and open-ended interview method, and the data were gotten by sketch, recording, photograph and memo. As a result, the followings were proposed. First, it was necessary to hide or reduce of the neighborhood's noise or direct view because those people thought the invasion of the privacy problem was very severe. The master planning of the complex method could be an alternative plan for this kind of problems. Second, it was needed to be the planning that could follow up the out-door friendly situations. To achieve this, the in between living space are needed that connected the outside and inside of the house. Third, the planning of the housing space should flexible for each participant's needs of the future. To achieve this, each unit in the suburban housing complexes should be fixed to the each character of the people's various needs.

The purpose of this study was to investigate desirable width / height ratio of enclosed space and to offer basic information for the design of enclosed spaces. The data of this study were gathered from the experiment through simulation. Photographic sampling of 7 campus sites located in Kwanak campus of Seoul National University and slides of perspective drawings of enclosed spaces with various D/H ratio (12, 1, 2, 4, 6, 9, 12)were used for simulation. A response format was made using the method of paired comparison and students from various departments were randomly selected for evaluation. In the method of analysis of data Thurstone's equation of Comparative Judgement was used for calculating preference score. A1so non-linear regression analysis was used for finding out relations between preference and D/H ratio. The other method of data analysis were correlation, Chi - test. And the results were summarized as follows. 1. In sketch simulation the ratio of D/H 4 got the highest preference store. This result suggests that desirable D/H ratio of enclosed space is D/H 4. And at the lower range of D/H ratio, as ratio increases, the preference score increases. At the higher range of D/H ratio, however, as ratio increases, the preference score starts to decrease from the cardinal point of D/H 4. 2. In campus photograph simulation preference is influenced by slope, elevation change of floor, trees, lawn area, familiarity, space arrangement, and exterior shape of building besides D/H ratio. 3. The preference virtue was not significantly affected by order effect. This result suggests that order effect can be ignored in the study of visual preference. 4. There are so many factors related to preference that it is difficult to explore those factors without scientific information based on scientific method. We must carry out study for scientific approach of planning and design based on precise, complete simulation technique.

Recent tendency in modern society for urban design and public space forming it recommended diversity of studies and design development, for the interest in urban design is increasing. In particular, street furniture being one of the important components to construct public space has been researched and developed in aspects of formative and emotional style, broken from the old way of the function-oriented purpose. It could be said that this results from the desire of human pursuing a well-off life, the new value standard regarding design and the life styles in mode. The new development of street furniture could be a creating the value-added source potentially being able to raise community, identity of nation and international competitiveness, beyond the primary purpose, namely the improvement of surrounding environment, and therefore the most of countries in the world are concentrating their life and death on development of design in reality. For this investigation the concept of city design, the basic content analysis of the street furniture and also the contents in the related sectors were reported. In order to develop the bench design, one of the representative items of the street furniture furthermore it was proceeded that basic process for the design like data searching for the object place and the existing case studies. On the basis of this the series of the design development processes such as idea sketch, computer rendering and drawing work were described step by step. The aim of this study is therefore to contribute in compiling the development processes of bench design as a new shape into a data and in utilizing it as a design case study and research material in the related sectors.
