The use of environmentally friendly finishing materials allows us to create a space where we can feel nature and to have stability and peace in the city center. In this paper, we examined the sensitivity of people to the three café spaces where wooden finishing materials are used in the space elements that change according to people's demands for environmentally friendly space due to pollution of living environment. First, we examined the wood and finishing materials and emotional vocabulary through literature review and previous research. Second, the values of L ^*, a ^*, b^* and sR, sG and sB values were extracted by using a line spectrophotometer (Ci6X). Third, we conducted a 7 - point scale questionnaire based on the extracted 13 pairs of emotional vocabulary. Using SPSS 21, frequency analysis by descriptive statistics, crossover analysis by visiting purpose and intention, and emotional lexical factor analysis were performed. Through the study, the following points were found. First, CB (The Coffee Bean), SB (Starbucks) and HS (Hollys Coffee) showed differences in CB (65%), SB (40%) and HS (37%) in the spatial analysis. Second, CB gave color similar to the color of wall and furniture wood, but HS changed the color or brightness of wood finishing color of furniture. HS or SB showed favorable use of wood color scheme. Third, SB (26.3%) and HS (19.7%) were selected by taste. Fourth, there were differences in the items of CB, 'local-exotic' and SB 'dark-bright' in the factor value. The use of wood finishing materials differed in the atmosphere evaluation depending on the spatial factors and the color of the furniture. However, in this study, there are many factors that are insufficient in the accuracy of the ratio of the applied wood finishing material to the space element and the amount of the survey. If we further study the evaluation of emotional image according to the ratio of wood finishing materials, we think that it is necessary to study now that interest in environmentally friendly is increasing.

본 연구에서는 프라이머 도포 여 부 및 압축강도수준 그리고 바닥 마감재 시공재령에 따른 주차장용 바닥 마감재 부착성능을 평가하였다. 또한 현행 KS 기준에서는 바닥 마감재 부착성능을 모르타르 공시체를 활용하여 평가하도록 제안하고 있지만, 실제 현장에서 바닥 마감재는 콘크리트 상부면에 시공되기 때문에 바탕면 변화에 따른 부착성능을 추가변수로 계획하여 평가를 진행하였다. 모르타르는 현행기준에서 제안하고 있는 배합표에 준하여 제작하였으며, 콘크리트 설계기준강도는 18, 30, 50 MPa로 계획하였다. 프라이머는 모르타르 및 콘크리트 재령 28일 변수에 따라 바닥 마감재와 함께 도포되었으며, KS 기준에 준하여 바닥 마감재 재령 일에 따라 부착성능을 평가하였다. 변수에 따른 부착성능 평가결과 바닥 마감재 재령이 경과함에 따라 바닥 마감재 부착성능은 향상되는 것으로 나타났으며, 압축강도가 높아짐에 따라 바닥 마감재 부착성능 또한 향상되는 것으로 나타났다. 이는 파괴양상을 고려하였을 때 콘크리트 쪼갬 인장강도의 영향을 받은 것으로 판단된다. 프라이머 도포에 따른 부착성능은 유사한 것으로 나타났으며, 프라이머의 사용은 부착강도에 문제없이 콘크리트 표면의 내구성을 향상시킬 수 있을 것으로 판단된다. 또한 콘크리트 및 모르타르 바탕면의 부착강도 특성을 비교한 결과 바닥재의 부착강도는 구성재료 보다 압축강도에 큰 영향을 받는 것으로 나타났다. 따라서 현행 KS 기준의 모르타르 바탕면 실험체의 부착강도를 근거로 실제현장의 부착강도를 예측할 수 있을 것으로 판단된다.

The biocompatibility and the fatigue strength of Co-Cr-Mo alloy are excellent, so it is used well for the material of artificial joints. The head of artificial joint needs mirror surface for reduction of abrasive resistance. Mirror finishing of Co-Cr-Mo alloy with geometrically defined single crystal diamond cutting tools is handicapped by micro chipping of tool edge. In general, it is said that the micro chipping of diamond tool is caused by work hardening of Co-Cr-Mo alloy for the cut. In the present research, mirror finishing of Co-Cr-Mo alloy by applying ultrasonic elliptical vibration cutting was carried out. The experimental results show that the micro chipping of diamond tool was suppressed and the tool wear was remarkably reduced as compared with the ordinary diamond cutting without elliptical vibration motion. It was confirmed that the good mirror surface of maximum surface roughness of 25 nmP-V was obtained for the cutting length of about 14 m. It is expected that mirror finishing of Co-Cr-Mo alloy can be achieved by applying ultrasonic elliptical vibration cutting practically.

To find out the effect of burn out print finishing for better quality of fabric, examined processing which could make less damages on the fiber because the biggest problem is remained fibers damage after burn out print finishing. Fiber damage examined to the condition of finishing material NaHSO$_4$and H$_2$SO$_4$, 3~10min., 100~13$0^{\circ}C$, glycerin. The fiber damages evaluated the break strength and the surface condition by SEM. Among satin, pile fabric which remained fiber is silk, warp knitted fabric which remained fiber is polyester, the fibers damage level were warp knitted fabric$0^{\circ}C$, glycerin and for 6 minutes by NaHSO$_4$. When carbonized by 20%. 50% and 70% to express textile design, carbonizing rate was not effect on the fiber damage very much. There was almost no damages with glycerine, and almost no damages during 3~6minutes fixation time, 10$0^{\circ}C$ steaming heat fixation by NaHSO$_4$and H$_2$SO$_4$. Without glycerine, there were damage by hydrolysis on polyesters surface and the fiver was broken by fixation time.

An internal finishing process by the application of magnetic abrasive machining has been developed as a new technology to obtain a fine inner surface of pipe. In this paper, a slurry circulation system was designed and manufactured. Its finishing characteristics was experimently investigated by various effective factors such as dry, water flow, oil flow with a slurry. From the experimental results, it was found that the materal removal and surface roughness were good in oil flow with slurry. The slurry circulation system is effective on the internal finishing of non-ferromagnetic pipe(SUS304).

The purpose of this study was to understand the current trend with regard to the material of jeans and the making method of jeans pattern and the characteristics of washing processing through the overall production status of jeans in casual brands and to offer the basic data for producing the high efficient jeans. The results were as follows. According to the survey of production status of jeans in casual brands, the fabric mixture was highest in the order of non-stretch denim 100% cotton, stretch denim cotton/spandex mix and denim with $1{\sim}2%$ weft direction spandex mix. The most frequently used processing method for denim was in the order of normal finishing, mercerization finishing, soft finishing and pigment finishing. The most frequently used method of washing finishing for jeans was in the order of forming by embossing washing, bio stone washing, normal washing, bio washing, and bio stone bleach washing. The average shrinkage was higher on waist circumference and pants length of warp direction rather than hips circumference, thigh circumference, hem circumference of weft direction.

The purpose of this study is to examine the advertisements of eco-friendly interior products and finishing materials in 3 interior design magazines which have been published for 4 years since 2002: to identify specific types of the products and materials that consumers can choose and to analyze their special ingredients which have functions and effectiveness related to health. Literature review and content analysis on the advertisements were employed. The results are as follows: The amount of advertisements has been continuously increasing due to the public concerns on well-being and finishing material types absolutely took the greatest proportion (92.8%) among them. Floor coverings, wall papers, and paints are the big 3 materials in the finishing material advertisements. The frequently mentioned health-related ingredients in them were charcoal, natural jade, nanosilver, yellow soil and quartz porphyry, And their main functions were emission of negative ions and ultra infrared. However, it's not easy to find their scientific test results on health. Objective guidelines are needed for the right selection of interior products and materials to maintain healthy interior environment.
