The purpose of this study was to investigate whether the standard models for rural housing and wooden housing model have performance for hygrothermal and to propose a way of improvement relevant to hygrothermal performance for those models. All of the models to be analyzed were found to have some parts that were absent of stability in terms of performance for hygrothermal. In the process of analyzing the causes and proposing improvement measures, the following conclusions were derived. Fist, The exterior surface of the structure should be composed of a structure with good moisture permeability, and for the interior surface, a variable vapor retarder paper should be applied in consideration of the reverse condensation phenomenon in summer. Second, in terms of performance for hygrothermal, applications of external insulation plaster finish to the exterior wall or of ventilation method using a rafter vent on the roof should be avoided. Third, a rain screen method with a ventilation layer should be applied to the exterior wall, and a method of constructing ventilation layer separated from the insulation layer with a vapor retarder paper should be applied to the roof. Fourth, the application of insulation materials having capillary action, such as wood fiber insulation board or cellulose insulation board, contributes to more stable performance for hygrothermal.

These materials in architecturally glass or metal have weaknesses such as inadequate insulating quality, combustibility and toxic gases in fires substance. However, Autoclaved Lightweight Concrete(ALC) has excellent thermal insulation properties and seem to possess the superb insulating quality as substitute of existing exterior materials. This research is to compare experimentally to the kind of the strength properties of ALC materials which mixed with blast furnace slag pounder and silica fume. For the purpose of increasing the strength, the plastic states of ALC evaluate the physical characteristics as microstructure and strength according to various specific gravity. According to the quicklime quantity the compressive strength is proportionate depend on the absolute dried specific gravity. When not putting in 10% quicklime, the compressive strength appeared most lowly with 14.0MPa. When putting in the quicklime, the strength appeared higher with 15.1MPa. And strength of specimen containing 2.25% silica fume is 15.6MPa increased 10.3% than reference specimen 14.0MPa.

The purpose of this study is to the design tendency expression of contemporary architectural matter, I can find out how the architecture is represented using the surface of building in its autonomy. I study backgrounds of contemporary architectural matter, method and their natures. In this case, i can notice that 'framework-dressing' method formed a objectified tectonic system, while it supplied arts with room that they hold priority to architecture. So it makes me find that contemporary architectural matter resided in relationship complicated between things and events. Also, this study on analyzing spatial effect by the figurative language derived by researching the dadaisme, pop art, kinetic art, video art hit In conclusion, analyzing the recent experiments in the expressive qualities of exterior skin, in their use of materials, methods of construction and visual effects, it can be argued that the new skin is inclusive of times, and has autonomic, constant and tactile features. Base on their immaterial vocabularies - limits, material, mouvement, media - these could be characterized as vibrant plates.

This study has been done to know concretely the designs of traditional American houses in eighteen century and their specific styles based on Deerfiled town and I found out followings. First, the traditional eighteen century houses in Deerfied had a 'L'shape exterior view and a flat facade and the front door made a symmetry with sash windows. A chimney had been installed in the middle of the roof and it usually had a gable with natural materials in a simple manner. Secondly, the most important factor to design houses was a front door and it had been decorated in luxury and in a display. Lastly, the traditional American houses in eighteen century had been greatly influenced not by the that of British which is commonly taken but by the various cultural backgrounds which represented regional characteristics and was rather simple.

The waste glasses among plenty of wastes put out lately is limited in recycling and reusing, and the phenomenon hasn't been improved quite much. And besides, the recycling rate shows the 70.1%, relatively low. These waste glasses is currently used for road pavement materials, interior and exterior decorating materials in architecture, road painting meterials, auxiliary lagging materials for heat-retaining, coldness-retaining and soundproofing, and glass bottles. 30% of waste glasses powder is, however, not reused pratically. Therefore, in this research, we operated some tests including flow of mortar mixed with waste glasses powder, setting time, rheology and compressive strength to utilize waste glasses powder put out in the precess of recycling for admixture for repair mortar. As a result, we've found out that we can utilize waste glasses powder for admixture for repair mortar.

Existing modular research has been mainly focused on S (shelter structure) and I (infill interior finishing material), and considerable research has been conducted, and the results are being proposed. However, in the case of the rest (exterior materials and windows, etc.), existing construction methods and materials are borrowed, and supporting hardware members and insulation materials are constructed on site, which acts as a factor hindering overall shortening of the construction period. That is, since the advantages and characteristics of modularity cannot be utilized in the absence of modular cladding, manufacturing of cladding is required. Therefore, it is necessary to develop a cladding system that can drastically reduce the construction period in factories while considering the structural characteristics of PC modulars.

This study analyzed the characteristics of spatial expression in the Barcelona Pavilion to be based on tectonics. Mies pointed out the image of materiality about the material rather than the process of tectonics using the material, and he also expressed demateriality in the image of each material through the reflection. To be liberated from structural matters, the wall has been introduced. He intended to show the design plan as the independent structural system, however, the wall actually seems to be supporting the roof that shows rather clearly self-contradictory because of the expression of materiality in the material. In terms of architectural elements; wall, roof, column, floor, and so forth, tectonic expression and abstract aesthetics stands face to face, because of hiding the productional process and transforming to line and surface in the image of materiality. The interior of the glass wall seems fairly closed space from the exterior, because materiality and reflection of materials of columns and podium. The character of experiential space is inconsistent and fragmentary because of the splendid images from maternality and reflection on the wall, and collision with the reality and the image the wall reflects, even though the geometrical space of the Pavilion's plan has the mutual penetrability and organic character.

The purpose of this study is create a comparative analysis of the characteristics of various materials which were used on the outer wall of F.L.Wright's works. The research results will be summarized as follows: 1) Wright thought that the outer wall was not just a physical object which divides the space of a house but it includes the image of the total exterior form, as well as, the economical factors of the age. 2) He tried to sublimate architectural image of his own style with the change of time because he recognized difficulties and limitations of traditional materials and economic feasibility. 3) He used nature-friendly material like wood and brick which were used in various methods of his natural architectural concept. 4) Some of Wright's early works were acculturated by classical architectural components such as the column to emphasize verticality of architectural form. The columns play a division role in the face of the outer wall creating a dynamic image and this also controls the amount of light that enters inside the house.
