For the moderns who spend more than 80% of the time inside a building, interior environment became important since it directly affects their health. Recently as noxiousness of the air contaminants of the interior space stood out as well as the above trend, the Ministry of Environment enacted a lawto maintain the interior air quality at certain level of standard in the multi use facility and newly constructed apartment. To make the indoor air clean, removal technology of various contaminants should be developed and interior materials with chemical treatment should be restrained. In other words, selection of interior finish affects indoor air quality from the initial design stage to the construction stage. However, only limited contaminants emission data of building materials are supplied by related companies. There is no average contaminants emission data for overall materials. Moreover, high cost and equipments for one time measurement of VOCs emission of interior finish are the obstacles of active research and data measurement. Therefore, this paper searched the current condition of average VOCs & HCHO emission of various interior finish based on the study requested to research center from the building material company through Stands Test Method for Indoor Air Quality.

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

This study aims by analysing the interior design elements trends of current medium size office buildings in Seoul. The analysing objects are ceiling, floor, wall, and illumination plan of current office buildings. Analysing tools are finishing material and color of each part. Analysing areas are lobby area, deskwork area, conference area, welfare area, public area(rest room, corridor, stair). The interior design elements of lobby shows a lots of different features then the other areas in ceiling, floor, and wall design. Such difference appears at finishing material especially, and the coloring is more splendorous then the other areas. Desk work area and conference area have similar characteristics in finishing materiors and colors, and they usually follow the needs of function. Walfare area shows more splendorous feature then deskwork and conference area, and designed by various materials and colors. Public area also shows very active design concept then past times.

Based on individual characteristics and values, human preference on interior finishing material is various . Finishing materials, however, do not seem to satisfy those characteristics and values. Given the aspects of life style and population classes, finishing materials are an important part of human life and draw much attention . As a result, there is a necessity to study them systematically. This study related finishing materials to tenants, understands the characteristics both of them, and identifies in terrelations between them in order to find out satisfaction and preference which teants have towards their finishing materials. As a result, this study is about design materials preference of tenants in apartment houses for the purpose of improving quality of finishing materials. A practical study method of questionnaire research was used to find out tenant's opinions on components of interior space.

Today aesthetics expression could be a 'Everyday-life Beauty', because today art & design are closely related with a contemporary life. This thesis dealt with a everyday-life and sensitive design which sublimate from everyday-life material to the concept of aesthetics, such a purpose of this thesis establishes a base of everyday-life design through everyday-life aesthetics. This purpose made to pay attention to Japan's aesthetics concept, because Japan has been maintained and developed its own everyday-life aesthetics. Even if Japan doesn't have only everyday-life aesthetics, it is useful that is studies as some kind of a prototype. So this study analyzed about a everyday-life aesthetics and the expression method through the case-study of Japan. According to Yonagi Muneyoshi and Leonard Koren, the Wabi-Sabi has three conceptual characteristics like impermanent, incomplete, and imperfect and six expression characteristics like implication, tranquility, simplicity, coarseness, purity, and association. This study process is as follows. In the first a vocabulary of interior design was derived from three conceptual characteristics and six expression characteristics, and spatial facts was abstracted from it, and then volume, form, and then shape of composition facts of interior space was extracted from it. Finally the expression characteristics of the Wabi-Sabi in interior design was derived from these processes. In conclusion, the expression characteristics of the Wabi-Sabi in interior design is the transitional space through a Shadow, the conversional space through form and material composition, and the copying space through a natural friendship.

Absorptive material arrangement method for effective interior noise control is proposed. Sound field with arbitrary boundary condition is formulated by Kirchhoff-Helmholtz integral equation. A simple example such as a rectangular cavity will present physical meaning between changing boundary condition and control of sound field. The effect of changing boundary condition is expressed in modal admittance. From this formulation. an admittance map is presented. The admittance map is the figure to represent position where absorptive material is attached for effective interior noise control. The admittance map can be assigned to each resonant frequency. There. however, may be common area of those maps. Then, frequency robust arrangement of absorptive material in noise control will be presented.

Interior material covering as the final process of house-building, critically influences not only aesthetic character but also air quality of indoor space. Wall covering today, however, caused a serious social problem because of chemicals contained in the industrial wallpaper and artificial glue. In this context, Korean traditional wall covering of Han-ji can be an alternative model due to it's ecological character. Recently 'Hanok' attracts public attention, since society and people become to appreciate the unique beauty and value of our traditional culture. The values include natural beauty, emotional character, and environment-friendliness. Recognizing this, this paper intended to scrutinize the operating process of Han-ji as an interior finish material. Historical research method was employed, tracing the related articles in old literature and interviewing with the witness of the experienced expert. Thereby, healthier and unique aesthetic indoor environment can be expected to be sustainable along with the rich cultural life of ancestors.

Use of processed timber can help reduce environmental damage and the economic burden of resources (important problems with use of raw timber) and can meet the needs of various fields where the sensibility of raw timber is required. Veneer wood is positioned as a high-value-added product due to its luxury and beauty, and it is used in various fields as a building-related material, such as interior decoration, furniture, flooring, building interior materials, and lumber. Dyeing is necessary to enhance the aesthetic appearance of this pattern and to expand its use. Therefore, in this study, we compared and analyzed the dye ability of oak-patterned materials with reactive dyes, and evaluated their performance as interior materials. As a result, the oak pattern was dyed with 9 kinds of reactive dyes and a comparative analysis was performed. The most suitable conditions are 50℃, 2 hours, and 0.5% o.w.f. In addition, evaluating resilience to daylight, resilience to rubbing, fire resistance, and flame retardance, yielded results suitable for use as an interior material. In this study, the dyeability of veneer dyed under various conditions using reactive dyes was compared and analyzed the performance as an interior material was evaluated.
