  • In this paper, we introduce the concept of fuzzy (r, s)-semi-irresolute mappings on intuitionistic fuzzy topological spaces in Sostak's sense, which is a generalization of the concept of fuzzy semi-irresolute mappings introduced by S. Malakar. The characterizations for the fuzzy (r, s)-semi-irresolute mappings are obtained by terms of semi-interior, semi-${\theta}$-interior, semi-clopen, and regular semi-open.

  • Composite materials were used widely due to merit of light weight, low maintenance cost and easy installation. But it is the cause of enormous casualties to men and properties because of weak about the fire. Particularly, it is more serious in case of subway train installed composite materials. For this reason, experimental comparison has been done fur measuring heat release rate(H.R.R) and smoke production rate(S.P.R) of interior panels of electric motor car using cone calorimeter. A high radiative heat flux of 50kW/㎡ was used to bum out all materials and to simulate the condition of fully developed fire case in the tests. It was observed that Heat Release Rate and Smoke Production Rate curves were dependent on the kinds of the interior materials. From the heat release rate curves, the sustained ignition time, peak heat release rate and total heat release rate were deduced, These data are useful in classifying the materials by calculating two parameters describing the possibility to flashover.

  • The purpose for this study shows general planning direction about showroom which can enhance sales promotion, and corporate image and through buyer negotiation increasing export. We can divide showroom as promotional showroom and institutional showroom as a whole. The results of this research can be summarized as follows : There is no uniformed design plan of display for the P.R of showroom. And they need independent business space. But, there is no attractive factors to fascinate their consumer and thus there is no sufficient service facility, Also, some more effective planning is needed to support their supervisors. I wish to suggest some planning direction on the basis of research problems : We need to divide four space- that is entrance space, display space management space, service space-to allocative effectively space for the purpose of charging product. P.R. We should set up uniformed design policy which can contribute P.R.-that is corporate color, unform . logotype, sign, pamphlet etc.

  • This study suggests experimental designs for interior products utilizing LEDs that are ideal for expressing diversity of light. It also attempts to develop various products by incorporating economic efficiency and diverse colors of LEDs into interior elements. LED door handles offer a range of 6-color LED lighting strips as a safety lighting system, while multi-function furniture (CUBE-scape) consists of LEDs with double-sided emitted lighting on completely transparent track structures. Both products are designed to make interior elements more user-friendly as they make most use of unique effects of LED such as light vibration and changes. Also the combination of plastic material-Technogel$^{\circledR}$, polypropylene, polycarbonate- maximize the LED lighting effect and diversify the designed item selection.

  • 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.

  • The purpose of this study is to examine the interior textile color changes and trends by analyzing the characteristics of interior color hues and tones. Heimtextil in the interior field was selected for color trend analysis from 1996 to 2000. The conclusions of this study are as follows: First, In terms of hue, warm colors like Y, YR, and R were most prominent in all four years. Some new colors, however, emerged with higher frequency. The frequency of GY and B increased in 96/97, GY, BG and PB in 97/98 PB and B in 98/99, and B and PB in 99/2000. Especially between 96/2000, the frequency of PB and B has been increased, although the frequency of GY has been decreased. Over the four years, P, RP, and Neutral showed medium frequency, and G and BG showed low frequency. Gold appeared as an accent color in two years while silver appeared in one year. In summary, warm colors like Y, YR, and R were most prominent in interior color. Second, In terms of tone, p, b, v, and sf were most prominent over the four years. Although 에 and ltg appeared with high frequency n general, a wide variation was presented. The tones such as p, dp, and v appeared with high frequency in the three years of 96/97, 97/98 b and sf in 97/98 ; lt, dk and sf in 98/99. On the other hand, a new trend emerged in 99/2000. In this year, ltg, sf, s, d and dkg appeared with high frequency unlike the other three years. In other words, soft or light tones, such as pale, soft, light, grayish, and deep, and strong tones, such as vivid and bright, appeared with high frequency.
