The factors to limit interior circumstance and the expression of the space start In the point how to provide the order in the interior space according to the intention of design. The controlling of the natural and artificial surroundings should be focused by synthesizing and analyzing the condition of circumstance, function, and emotion to provide the comfortable room to a customer in a fitness center. A fitness center aiming at the future requires various function according to it's role depending on the change of the social values. In addition, the fitness center reflecting the various regional culture according to the change of values requires the expansion of the cultural and life space. The characteristics of fitness space like this affects the mental effect of a customer with the color and quality of the materials suitable for the characteristics of grouping, continuity, symbolism, and generation as well as the unification in the total design and the simplicity of maintenance and management. The paper aims to extract factors related to the circumstance plan of the interior and to suggest it's application in the interior design. The design applicable to the circumstance plan of the interior will keep changing according to the social change and the change of the understanding along with the factors. The continuous research on the interior circumstance planning of a fitness center could be approach to develop in a systematic method and the paper will be expected to be a little step toward it.

Buildings' outward appearances, sidewalks, and street lights have long been regarded as important factors identifying the street landscape of a city. On the other hand, the interior spaces of a building have been known to have less correlation with street landscape. This paper, which did not use standardized urban street landscape application methods, attempts, based on an experiment involving Pimatgol, to prove that small changes in interior design influence the street landscapes of cities and even provide new vigorousness. Pimatgol is a type of village that still possesses a traditional Korean lyrical atmosphere. This paper also attempts to, with the use of a physical model and a digital simulation of small changes interior design, such as changes in materials, size of the opening, location of furniture, or a change of lights, uncover positive changes in street landscape. Computer simulation is one of the extraordinarily useful techniques to predict lighting performance, changing interior space and present visual image. As a result, this study can be a valuable guideline for the future streetscape reform project to lead the demanding effects of the interior space.

In this paper, we describe the analysis of interior noise for tilting train that is being developed in Korea. Tilting train is made of composite material to reduce the car body's weight and attached a self-steering system on bogie to improve curving performance. However, the acoustic performance (Transmission Loss) of such material is worse than the materials of conventional train, such as aluminum, steel and so on. Therefore, we measure the transmission loss of side wall / floor of tiling train and predict the interior noise for tilting train using its measuring results

Between multiple components of the building, materials have a direct impact on the environment. For many researchers have proposed guidelines for green design materials. However they didnt provide concrete criteria for selecting materials for selecting materials for achieving green design. From the perspective of this point, this paper proposes. Performance information expressed numerically is the most important factor. The purpose of this study is to provide the specific information about the performance of materials that has been ranked quantitatively. The performance information can be utilited in selecting materials for green design.

The interior materials of the urban subway car in operation are now being changed to new materials that meet the latest law in effect, the fire safety criteria of the urban railway vehicle. It was well known fact that the composite materials, that were applied to last subway car, were weak on the fire. Contrary to this materials, materials in work have good resistance to the fire. On the paper, To investigate the difference of fire safety level on the subway car, cone calorimeter was used to measure the heat release rate and total heat released according to the ISO 5660. A high radiative heat flux of 50kW/m2 was used to burn out all materials and to simulate the condition of fully developed fire case in the tests.

Frankincense resin was applied to Hanji to improve its physical properties. The resin-treated paper showed the increasement of physical properties such as weight, thickness, and density. The highest increasement in weight and density of resin-treated paper were found at 30% treatment concentrations and the largest values of density were $41g/m^2$ Hanji. With the increasement of concentration, the brightness was decreased and transparency was improved. Of the mechanical properties of the paper, the tensile index and burst index showed the improved values. The tear index, however, was decreased. The frankincense resin showed the highest result in the tensile index of resin-treated paper and the basis weight of $41g/m^2$ Hanji. The air resistance of the resin-treated paper got improved with the increase of the concentration and $105g/m^2$ Hanji showed the highest values. The highest improvement in air resistance may make the resin-treated Hanji possible to use for semipermeable materials.

The construction projects are recently having changes in their magnitude and complexity. Therefore, the amount of information created and managed by participants over project phases is enormous and this may cause difficulties in consistent and integrated data management. Because of the change in construction projects, there is a need to apply more logical and systematic ways to deal integrated data management. For the solution to this, BIM(Building Information Modeling), a new paradigm for integrated management of the information over project life-cycle, has been seriously considered. Also, the Korean Public Procurement Service announced that project over 50 billion Korean Won should introduce BIM into procurement starting from 2012. However, the studies and development have lack on studies of applying BIM and managing the data made using BIM in pre-design and maintenance stage. In pre-design stage, the concept of schematic design model is made to support for making major decisions concerning the size, shape and cost of the project. To decide the cost for the building in this stage by making use of BIM, estimating the amount of building materials used for constructing should be preceded. In this study, the pre-design BIM is explained to gain a better understanding of its process, since this paper focused on space programming stage. Finally, the paper suggests the concept process of estimating the amount of materials in building interior finishing from selecting the type for the elements of each space made to support the client for making decisions in space programming stage based on pre-design BIM.

To improve the mechanical properties of Hanji, starches such as maize, konyaku, and wheat powders were added at various concentrations in the manufacturing processes of Hanji. The effect of starches on the physical properties of Hanji was as follows. Filling rates of surface of hanji were increased with the increase of the concentration of starch. Hanji surface were completely filled at the 3.0% konyaku treatment. Konyaku powder showed higher filling rates than maize and wheat powder. The breaking length was increased with the increase of filling rates. Konyaku powder showed the highest breaking length: Tear index of hanji treated with maize and wheat powder were a little improved but that of hanji treated with konyaku powder were a little decreased compared to non-treated hanji. In conclusion, starch treatment showed the increase of the breaking length, but no effect on tear index.
