Technological development are now encouraging new concepts in various fields of design, including material applications. Metal can be considered as the major material that represents modern design and technology since the industrial revolution. The objective of this study was to understand characteristics of metal as design material and various application methods in interior design. This study first examined basic qualities of metal and its history used in architectural design. Secondly, based on three qualities of metal such as physical, chemical, and mechanical the authors have analyzed projects built within recent 10 years regarding aspects of metal qualities, treatments. As results projects that uses a combination of two or more qualities and treatment seem to have a more interesting affects in interior space. Moreover, each affects are related to these four design keyword: visual distortion, de-materialization, hi-technology, and time-concept. The framework developed is hopes to be used as a basic design guideline, where metal is considered not just as a mere interior finish material but as a major creative source and inspiration in interior design.

The advancements of the society aggravate ecological problems, and it is at a point where our living environment is under a serious threat. To resolve such problems, environmental friendly design concepts are evolving through various naming conventions such as conservation of global environment, environmental symbiosis, friendly environmental, nature-friendly, environmental friendly type, green building and eco-construction. Accordingly, in this research, for the purposes of healthy living environmental construction, nature as the subject of its design and highly praised as a new design arena, floral art design theory and its functions, as well as its examples are explored. With the Information available, I was able to confirm that, in interior decorating, floral art design is used as a tool for expressing environmental friendly space, and gradually its necessity and the scope of its application have been broadened. Therefore, utilization of floral art design is to fabricate environmental friendly interior space; and it is expected as a substitute for accomplishing green amenity, and its study should continue for the years to come.

In order to develop urban underground spaces, even microcracks should be reinforced. In this paper, the grouting injection performance for microcracks was investigated considering the viscosity and particle size of the grouting materials, injection pressure, and crack width. There are two types of typical grouting materials used for filling micro-cracks. One is a chemical liquid grouting material which is a solution type and the other is a cementitious grouting material which is a suspension type. The injection performance of the grouting materials for microcracks is generally influenced by the viscosity, and the injection performance of the cementitious grouting material is additionally affected by the particle size. From laboratory tests, the viscosity was calculated inversely to provide a suitable viscosity measurement method for each grouting material. The groutability ratio based on the relationship between the crack width and the particle size was evaluated to estimate the grouting feasibility of the cementitous grouting material through microcracks.

Current methods for lateral thrust calculations are based on the classical formulations of Rankine or Coulomb. However, the previous studies indicate that lateral earth pressures acting on the wall stem, which is the function of deformation parameters of the backfill, are close to the active condition only in the top half of the wall stem and in the lower half of the wall stem, the lateral earth pressures are significantly in excess of the active pressures. This paper presents the compressible inclusion function of EPS which can results in reduction of static earth pressure by accomodating the movement of retained soil. A series of model tests were conducted to evaluate the reduction of static earth pressure using EPS inclusion and determine the optimum stiffness of EPS. Also, field test was conducted to evaluate the reduction of static earth pressure using EPS inclusion. Based on field test it is found that the magnitude of static earth pressure can be reduced about 20% compared with classical active earth pressure.

Generally, an unsaturated condition was not considered to predict the long-term strength and drainage behaviors on compacted road foundations. However, it is logical way to consider the unsaturated condition and hysteresis behavior on road foundations like subbase and subgrade. For more quantitative analysis, rational experimental approach requires proper laboratory tool and material model, and hydraulic properties of pavement geomaterials under unsaturated conditions. In this study, therefore, laboratory data from the soil-water characteristic curve tests were used to predict suction and unsaturated permeability on pavement foundations and the results were analyzed based on the nonlinear fitting model considered. In addition to that, the unsaturated moisture capacity of each material is discussed.

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.

본 연구는 과학적이고 실험적인 접근을 통하여 공간의 비례와 실내음향과의 상관관계를 규명하기 위하여 체적과 마감재료가 같고 비슷한 기본축척의 모델을 중심으로 가로, 세로, 높이의 비율이 다른 4개의 모델에서 각각 SPL, EDT, C, RT, LEF, IACC 등을 측정하여 각 형태의 모델의 값을 비교 분석하였다. 실험결과 잔향은 동일한 체적인 경우 음원으로부터 평균거리가 멀리 위치한 장방형의 형태가 양쪽 측벽 사이의 거리가 넓은 장방형보다 잔향시간이 긴 것으로 나타났다. 음압은 실의 체적이 작고 음원으로부터의 평균거리가 짧은 순서로 큰 반면, 명료도는 잔향의 크기순서에 반대로 분석되었으며 특히 음원으로부터의 직선거리가 짧은 순서로 명료도가 좋게 나타났다. IACC는 양쪽 측벽의 거리가 가장 긴 모델에서 가장 작게 나타났다 그러나, 초기 음장에서는 그 변화가 작게 나타났는데 이것은 IACC가 실의 형태에 장시간 관여하는 지수라는 것을 의미한다.

Nowadays tiles are widely used as architectual material because of their external beauty, solidity with fire-resisting and water-resisting qualities, and convenience for construction, preservation and repairs. Owing to the improvement of living standard and makers scramble for tile markets, we regard tiles as art and culture. Tiles have been developed with technical improvement, based on mutual relation of material and design. The purpose of the third firing is to create high value added as we show artistic merit and decorative effect. For this reason, researches on new material and design have been carried out widely. I made researches whole process from design to printing by means of computer and experiment with color and vetroza of the third firing. I hope that tile makers will share the achievement of university researchers and this paper will be useful for those who are interested in tiles.

This study deals with 'Sachlichkeit' , as essence of materiality that architectural building materials process, which forms the physical basis for actual building. There have beennu merous researches that deals with various elements that compose architecture, but the emphasis seemed to be concentrated on the meta-physical discussion concerning formal concept. An issue on sachlichkeit as materiality does not necessary mean to mention production process of architecture, rather it is aim of this study to seek possibility to find elements that generate architectural form, through interpreting meaning of materials as substructure generator to make architectural possible. Architectural act can be defined as a process where physical material in life is composed into architecture by the hands of architect. Material used in life is composed into architecture by the hands of architect. Material used in this process basically has neutral characteristic, so 'Sachlichkeit'solely depends on the intentions of architects. This study interprets the intention of architects through the frame of modern-basis proposed by Hilberseimer, and a result architecture is defined as an object projected by architect's subjectivity.
