  • Textile fabrication affected by consumer and selected by fashion designer. The textile fabrication has been made not only by introducing the newly developed fiber but also by modifying the existing textile materials to impart sensibility to them. Consumers choose but to their sensibility of textile material and fashion trend. On purpose in this research is find out have influence on textile image. Wool fabrics have been in use from early age in northern Europe. Recognition of the role of the morphological structure, surface properties, chemical composition, acid-base characteristics in the chemical treatment of wool led to quantum advances in the fields of setting, shrink-resisting, chemical modification, and internal fiber cross-linking. Mechanical finishing to develop the handle, drape, and surface characteristics of the fabric is at least as important as chemical or wet finishing. Result showed that to have variety sensibility and trend theme in wool fabrics are tweed, venetian, serge, gabardine and melton.

  • The factors influencing the floor impact sound insulation include floor finishing materials, shock absorbing floors (slabs included), and ceiling structures. The ceilings of the apartment houses, currently built in Korea, are set up with lower parts of slabs and paper finishing, or with double floors for protecting against floor impact sounds in order to improve the sound insulating performance. The most common the method of ceiling structure construction consists of 'wood boarded frames + Gypsum boards + ceiling papers', which is called the wood boarded frame method. This study aimed to measures and evaluates floor impact sound insulation by which the ceiling space are widened according to suppression system is added in apartment house ceiling structure.

  • Recently, in circumstantial situation it is recommended positively to utilize of EIFS(Exterior Insulating and Finishing System) as energy policy for economizing energy. But internal EPS insulators of EIFS are exterior panel of high fire risk, because of constituting of flammable materials to be fragile in fire. In this study, fire risk is assessed by experiment Con Calorimeter test and SBI(Single Burning Item) test. As the result of experiment, Con Calorimeter tests do not reach to capability standard of internal incombustible grade, and are assessed as low grade in SBI incombustible grade. Because EIPS is exterior material in buildings with high fire risk in spite of good efficiency, it is required rapidly to take measures to meet situation through various studies(for instance, adjusting law regulation, etc.) in the future.

  • Many studies about carbonation experiments which result in deterioration of the Reinforced Concrete(from now on RC) structure have being done by now. But most of the studies are about RC itself without thinking of finishing materials. So in this study, we experimented to know restrain-effects which each finishing material has for carbonation. On the basis of experiments, we estimated velocity coefficient for carbonation. We want to show basis data about how much each surface-finish has a restrain-performance against carbonation.

  • New forward slip model has been developed for the precise prediction of rolling speed in the hot strip finishing mill. Besides those influential factors such as neutral point, work roll diameter, friction coefficient, bite angle and the thickness at each side of entry and delivery of the rolls, roll torque was specifically taken into account in this study. To consider the effect of width change on forward slip, calibration factors obtained from rolling torque has been added to new prediction model and refining method has also been developed to reduce the speed unbalance between adjacent stands. The application of the new model showed a good agreement in rolling speeds between the predictions and the actual measurements, and the standard deviation of prediction error has also been significantly reduced.

  • In modern times, due to the centralized urban structure, the interval between buildings is narrow and the increase of the heat island phenomenon due to the accumulation of the structure is becoming a social problem. In order to solve these problems, various materials for reducing the surface temperature of buildings are under study. Particularly, in the case of a wall part which is a part directly affected by the outside air of the building, it is a main structural part for determining the room temperature. The purpose of this study was to develop a material that can improve the thermal environment performance of the building by evaluating the temperature control performance of the exterior finishing material using the heat reflecting material as a method for controlling the temperature of the outer wall finishing material.

  • The thermal fatigue and wear properties of high speed steel roll which was recently developed were investigated by observing microstructure, by measuring mechanical and physical properties, by conducting thermal fatigue testing, and by measuring the amount of wear in actual mill. High speed steel roll had better thermal fatigue testing, and by measuring the amount of wear in actual mill. High speed steel roll had better thermal fatigue life than high chromium iron roll, which was due to lower carbide content, higher strength, and higher thermal conductivity. The amount of wear of high speed steel roll was nearly the same as that of high chromium iron roll in the first finishing stand, which was due to the oxide formation on the roll surface. However, in the third finishing stand, the wear resistance of high speed steel roll was 2~3 times as good as that of high chromium iron roll because the former had higher hardness at high temperature.

  • Recently, a bed company's product has detected a certain level of radon or higher, making it a popular search word on portal sites. Because of this problem, people are becoming more interested in radon. The government plans to support the establishment of a radon alert system for households through a radon concentration survey of 10,000 households. The use of palm charcoal as an indoor finishing material will reduce the risk of lung cancer through radon reduction. The experiment used a method of replacing palm activated carbon with blast furnace slag, and the adsorption performance of radon tends to increase as the replacement rate of palm activated carbon increases.

  • In order to improve wear and fatigue resistance of the structural materials, especially cold work roller for 304 stainless steel, an eco-super-finishing and surface hardening treatment using ultrasonic vibration energy was developed and applied to the SKD-ll roller. The eco-super-finishing machine was designed and fabricated by DesignMecha Co, by its own technology. It was observed that the surface roughness, hardness and residual stress were changed from $Ra{\;}={\;}O.25\mu\textrm{m}$, Hv=710 and ${\sigma}$={\;}+400{\;}MPa{\;}to{\;}Ra{\;}={\;}0.165\mu\textrm{m}$, Hv = 1200 and ${\sigma}=-610$ MPa after 20 KHz micro-cold forging, which means almost equal to the 300 % improvement of life-time.
