This study aimed at understanding the spatial characteristics in the Tugendhat house. For this study, it is need to analyze the early plans of the Tugendhat house design process. To analyze this, the study leads to how to effect on the real practice with the process. Therefore, this research investigates the conceptional design process of the house. There are 2 main characteristics of the interior space alternation. One is the closed spatial character on the 2nd floor, the other is the open spatial character on the 1st floor. It clearly shows the severance between interior and exterior on the 2nd floor. Each 2nd floor's space volume uses different materials so that each the space can show the individuality. On the 1st floor, however, it seems the interior is not as much open to the exterior, because the materiality and reflection of the glass, the objet of furniture and wall. In case of 1st floor, it has a complex concept as open and close character, because it is using the proper gardening elements and the relationship between the house and site. The exterior characteristic is separated the house from the ground with the podium and the slope, and this leads to have the discontinuity. The house clearly shows the spatial characteristics of the continuity and discontinuity, it proves that Mies tried to move onto modem architecture as a turning point.

Dwelling refers to a way of being that has to do with a cautious and guarded attitude. What has to be nurtured and preserved is the dweller's relationship with the fourfold of heaven and earth, divinities and mortals. This leads to the fourfold definition that mortals dwell insofar as they save the earth, receive heaven as heaven, await the divinities as divinities, and are capable of death as death. Heidegger sees the thing as the concrescence of what he calls the fourfold of earth, sky, mortals, and divinities. For Heidegger, true being means to be open to the fourfold, to tend the fourfold in its essence. C. Norberg-Schulz takes as his starting point Heidegger's notion of the thing as that in which the fourfold is assembled. The built space must be organized in a way that concrete places are created, places that are characterized by a specific genius loci. This idea refers to life in the warm seclusion of a traditional community, but is much less applicable to the functional networks and relationships that determine life in a modem society. Cacciari thinks that what is worth questioning is in particular the condition of homelessness perceived by Heidegger, and the possible consequences of this situation for architecture. The aim of this paper is to study the meaning of dwelling through Heidegger's concept of dwelling and the interpretations of C. Norberg-Schulz and M. Cacciari about it.

This paper presents a novel K-band (18 GHz) 16-quadrature amplitude modulation (16-QAM) orthogonal frequency-division multiplexing (OFDM)-based $2{\times}2$ line-of-sight multi-input multi-output communication system. The system can deliver 356 Mbps on a 56 MHz channel. Alignment mismatches, such as amplitude and/or phase mismatches, between the transmitter and receiver antennas were examined through hardware experiments. Hardware experimental results revealed that amplitude mismatch is related to antenna size, antenna beam width, and link distance. The proposed system employs an alignment mismatch compensation method. The open-loop architecture of the proposed compensation method is simple and enables facile construction of communication systems. In a digital modem, 16-QAM OFDM with a 512-point fast Fourier transform and (255, 239) Reed-Solomon forward error correction codecs is used. Experimental results show that a bit error rate of $10^{-5}$ is achieved at a signal-to-noise ratio of approximately 18.0 dB.

Recently, ground source heat pump (GSHP) systems have been introduced in many modem buildings which use the annually stable characteristic of underground temperature as one of the renewable energy uses. However, all of GSHP systems cannot achieve high level of energy efficiency and energy-saving, because their performance significantly depends on thermal properties of soil, the condition of groundwater, building loads, etc. In this research, the effect of thermal properties of soil on the performance of GSHP systems has been estimated by a numerical simulation which is coupled with ground heat and water transfer model, ground heat exchanger model and surface heat balance model. The thermal conductivity of soil, the type of soil and the velocity of groundwater flow were used as the calculation parameter in the simulation. A numerical model with a ground heat exchanger was used in the calculation and, their effect on the system performance was estimated through the sensitivity analysis with the developed simulation tool. In the result of simulation, it founds that the faster groundwater flow and the higher heat conductivity the ground has, the more heat exchange rate the system in the site can achieve.

Organic Modernism was inaugurated by Alvar Valto as an alternative plan to the formative limitation of Geometrical Modernism. It began to appear in the 1930s in the fields of Architecture, Furniture, Product Design and so on. It is known that began with organic formative language is closely related to surrealistic artists Andre Breton as well as other artists and sculptors in that era. Such Formative Language formalized a stream of Organic Modernism Furniture Design unique to the regional and cultural characteristics of Scandinavia. After crossing over to America, mass production of Furniture was born and new materials were linked by industrialization. The Characteristics of Organic Formation in Modern Art such as Three -Dimensional, Biological Morphological, Symbolical, Primitive, Fantastical, Non-Realistic, Incidental, Irregular, transmit to Furniture Design. They are as Characteristics especially with Three-Dimensional, Biological Morphological and Symbolical aspects. Histories of Art and design, there are some examples showing mutual Interchange between Functional and Artistic Character. This thesis also clarifies the Formative Relationship that the Furniture designers who pursued Functionality and Mass Production had obtained from Modern Artistic works and the Artists, through the process of comparing and researching the typical Artists and their works.

The concept of time-space to be seen in the modem society has complex features at the points of scientific, philosophical, artistic, religious point of view. It has been brought up at a points of neo centric religious, philosophical view and then after, phenomenal approach and scientific approach were rendered through Newton and Einstein and so many scholar approaches affected the artistic field significantly. With such visual expression, it has affected the paintings for a long time till the 19th century, and then has affected various fields such as photography, film, video, computer, architecture and has currently affected the various space expressive of our daily lives and virtual space of digital. This study is to extract a visual and expressionistic characteristic through historical examination and multi-scholar analysis of time-space concept. Especially, by expanding the previous time and space concept, experimental cases and expressionistic characteristics has come up on the media art that offers various experience and by analyzing the expressionistic characteristics of the time-space concept expressed in media art, it is to extract the basic factors for the diversity of space experience.

In choreography, the relationship between body and space is fundamental. Not only in the performing arts, it is an essential part in space design as well. In this sense, the comparison study between performing arts and space design will have various helpful aspects from which a creative design can be derived. This thesis aims to study spatial characteristics and expression methods in the choreography of performing arts that is dance in this case. The general background study of the relationship between body movement and space design in the modem art and architecture was explained in advance. And then its application in choreography was studied. Two case choreographers were selected: Merce Cunningham and Frederic Flamand. They have unique ways of designing and choreographing the relationship between body movements and stage spaces. This thesis attempts to find the differences as well as common characteristics between the two choreographers in terms of how they relate bodily movements and emotions into the given space.

Reflecting the idea of benevolent royal government of King Jeongjo(鼎俎), the Buyongji(芙蓉池) and Juhamru(宙合樓) of Changdeokgung(昌德宮) are the traditional Korean architecture to represent the Joseon(朝鮮) period. The purposes of this study were to investigate how the Likiron(理氣論), one of the foremost theories of Joseon Confucianism, was applied to the principle of space composition by analyzing Buyongji and Juhamru with Jung's analytical psychology and to provide basic data to utilize the results in modem space planning. The research findings indicate that Buyongji is the space of Ki(氣) to reflect the reality, corresponds to conscious, and represents the Joseon land and people including Chiljeong(七情) And Juhamru is the space of Li(理) with the ideal of benevolent royal government inherited in it and represents unconscious. It also has each building placed which contained the nature of Sadan(四端) along with Gyujanggak and Jewolgwangpunggwak(齊月光風觀) to represent "Self Archetype" that's the core of human mind. Each representing Ki and Li, Buyongji and Juhamru must have worked as a major composition principle of Likilwonronjeokilwonron(理氣二元論的一元論) that could simultaneously satisfy the practice philosophy of reality and ideal among Likiron.
