This study is aimed to grasp the spatial characteristics exhibited in the modern housing architecture from the aspect of a geometrical manipulation, which transforms basic geometrical shapes and persue the formative diversity, to identify and verify the various characteristics of spatial structure in modern housing architecture. In this regard, this paper analyze and identify the influences of the void spaces that are created by geometrical manipulations on housing architecture, in terms of morphological and environmental aspects. Theoretical approaches define the concept of geometrical manipulation according to the characteristics of residence and examine the spatial features of void spaces. Additionally, case studies result in the classification of void spaces that are created by geometrical manipulation. Furthermore, to understand environment-friendly characteristics of the void space, the researcher elicited the factors that can affect environment friendly housing from previous studies, and analyzed their correlation between those factors and the void spaces that are classified.

The criterion of 'void space' in this paper is based on the sense of unusual experiences to afford the improvement of the value of cultural life with the sense of Healing. The more chances to spiritual converse with nature and oneself, the higher the value of healing experiences that one has will grow. This analysis has been done on the premises that this is derived from the inner conversation with 'nature' and 'oneself', as well as among 'others'. In other words, while the 'community void' affords programmatic aspect in relations between humans, the 'ecological void', systemic aspect in relations between human and nature, the 'meditation void', the aspect of image in relations between human and human's inside. Jong-soung Kimm and Hyo-sang Seung are Korean architects who have consistently expressed contrastive essential characteristics of the 'void space' in their contemporary works. While the void space of contemporary Korean architectures have shown various external forms, there has been a trace deeply rooted from the absolute and neutral concepts of the masters of Modern architects and 'Madang'of Korean traditional space. The integrated composition in the works of Jong-soung Kimm suggested integrated characters and healing affordances of 'Madang', but it hardly showed the poetic simplicity that could be seen from the image of traditional 'Madang'. On the other hand, the works of Hyo-sang Seung represented the simple and silent image of 'Madang', but showed fragmented characteristics that didn't sufficiently afford the integrated healing functions of 'Madang'.

Purpose: Planning space of the house is important as a universal place to relieve stress of contemporary people. Void space is easy to perform mental and cultural programs in aspect of affording the healing behavior. The "Interface" accommodates healing behaviors through mutual interchange between void space and solid space as the edge of the solid space around void space. This study presents a efficient theory of healing space through combining space theory with the Kitwood's theory of psychiatry used for the art therapy. Methods: Spatial elements based on Kitwood's theory converges towards 2 behavioral elements; Meditation(-), Sense of Community(+). Balancing with reciprocal complement between behaviors of passive and stable "Meditation(-)" and active and released "Sense of Community(+)" was analysed. Results: "Faciliation" can be used in combination with "Flow(+)" as active factor. "Validation" is combined with "Prospect(+,-)", and divides into 2 factor ; "Recognition-Refreshment(-)", "Reaction-Social Exchange(+)". "Holding" is combined with "Refuge(-)" as passive factor. Implications: This study established concept of spatial healing elements in connection with theory of Psychiatry about Alzheimer that is extreme situation of stress. This study is expected to enhance the validity and efficiency in analysis of healing space.

Rem Koolhaas has pursued new architectural approaches breaking with conventional ones. Around the 1990s when large-scale projects occurred with the union of Europe ahead, Koolhaas recognized the limits to the existing methods for responding to such changes. Accordingly, he came to use design methods based on 'congestion' and 'void' as strategical alternatives, which became the moment for him to leap forward from the previous working sphere based in Europe to becoming an architect who would be commissioned a number of large-scale global projects. Therefore, this study intends to investigate his design methods which utilized congestion and void, and to derive spatial characteristics from the projects based on such methods. First of all, the study looked into the historical background, definition and process of congestion and the void as design methods, and analyzed his projects to which such methods were applied by classifying them into the following categories: 1) the void that removes a space of singularity; 2) the void that penetrates space while making a flow; and 3) the void that is formed by vertical extrusion. Then, the characteristics of architectural spaces made in this way were identified as 1)the single-body appearance made by congestion and the following types of space made by the void: 2) the non-uniformly shaped space that looks like floating; 3) the flexible space with various flows and directions; and 4) the space with virtual possibilities that embrace contingent events. This understanding of Rem Koolhaas's design methods which were attempted in various ways at his critical turning point will be the foundation to understand the overall world of his works.

Spatial distribution of void space in concrete materials strongly affects mechanical and physical behaviors. Therefore, the identification of characteristic void distribution helps understand material properties and is essential to estimate the integrity of material performance. The 3D micro CT (X-ray microtomography) is implemented to examine and to quantify the void distribution of a lightweight aggregate concrete using an image analysis technique and probabilistic approach in this study. The binarization and subsequent stacking of 2D cross-sectional images virtually create 3D images of targeting void space. Then, probability distribution functions such as two-point correlation and lineal-path functions are applied for void characterization. The lightweight aggregates embedded within the concrete are individually analyzed to construct the intra-void space. Results shows that the low-order probability functions and the density distribution based on the 3D micro CT images are applicable and useful methodology to characterize spatial distribution of void space and constituents in concrete.

In the one-dimensional thermal-hydraulic (TH) codes, a subcooled boiling model to predict the void fraction profiles in a vertical channel consists of wall heat flux partitioning, the vapor condensation rate, the bubbly-to-slug flow transition criterion, and drift-flux models. Model performance has been investigated in detail, and necessary refinements have been incorporated into the Safety and Performance Analysis Code (SPACE) developed by the Korean nuclear industry for the safety analysis of pressurized water reactors (PWRs). The necessary refinements to models related to pumping factor, net vapor generation (NVG), vapor condensation, and drift-flux velocity were investigated in this study. In particular, a new NVG empirical correlation was also developed using artificial neural network (ANN) techniques. Simulations of a series of subcooled flow boiling experiments at pressures ranging from 1 to 149.9 bar were performed with the refined SPACE code, and reasonable agreement with the experimental data for the void fraction in the vertical channel was obtained. From the root-mean-square (RMS) error analysis for the predicted void fraction in the subcooled boiling region, the results with the refined SPACE code produce the best predictions for the entire pressure range compared to those using the original SPACE and RELAP5 codes.

Exaggerated expressions of contemporary fashion have exceeded historical precedents in volume. The purpose of this study is to understand the aesthetic characteristics of expanded form In contemporary fashion. To take dresses beyond their flat shapes into three-dimensional forms, it was investigated into volume of dresses by using the void and the mass. The void Is rarefied space and the mass is densified space. The void of dresses could be constructed from the boning such as panier and stiff textiles as organza lining. The mass could be constructed from padding. Fold, pleats, twist, and the layering of fabrics show features of both the void and the mass. Contemporary fashion designers relied on the void rather that the mass to make the enormous volume because of the weight of the mass. X-silhouette and the expansion of skirt and sleeve were dominant as the result of accentuating the body with a waistline. However, many of expanded dresses were so voluminous that they obscured the body's outlines. Some forms were strange and shocking. Many designers explored the void and there were a multitude of methods to construct the void: compartments of air, architectural techniques, technical textiles, fold such at origami. The aesthetic consciousness of expanded dresses could be classified into 7 categories, the giant, the dynamic, the deconstructive, the historical, the comedic, the rhythmical, and the technical character.

MVRDV is most important architect as created interesting architectural space in contemporary architecture, and so they applies to the unique theory in their architecture. They used to architectural diagram, program, datascape, density as a design tool. Especially, they have create new architectural space and form in using architectural diagram, program, datascape, density, and void. So, this study is purposed to explain how they use as architectural tool to make composition of it's architectural space and is purpose to explain what is their main concept in architectural space. MVRDV's architectural space has fundamental methodology. That is Datascape on uncertainty and continuity between urban space and architectural space. The former consist in using diagram and architectural program and the latter consist in operating architectural void and inner continuity surface. The conclusion is follows 1. The mode of spacial composition by architectural void is correspond density of city as MVRDV's architectural thinking. 2. The mode of spacial composition by architectural program is ambiguous to the boundary between inner and exterior space by transparency. 3. The mode of spacial composition by architectural diagram make to generate the architectural form and space, through the reinterpretation and relocation of architectural program. 4. The mode of spacial composition inner continuity plane is make relative between site and inner space.
