다중이용시설에서 많이 사용중인 바닥마감재를 대상으로 연소가스의 독성을 NES 713의 방법에 의해 평가하였다. 또한, 공기가 공급되지 않는 밀폐된 공간에서의 연소시 각 시료에 따라 발생할 수 있는 유독성가스를 가스분석기를 이용하여 시간변화에 따라 연속적으로 측정하여 비교·분석함으로서 화재 시 내포하고 있는 바닥마감재의 위험성을 평가하였다. NES 713 방법에 의한 각 제품의 유독가스의 독성지수를 살펴본 결과 2～9.7의 값을 갖고 있으며, 화재시 유독가스에 의한 매우 큰 위험성을 내포하고 있다.

A silicone softner (SS-5), a permanent press (PP) finish, was prepared by blending silicone oil KF-96 (as a lubricating component) and beef tallow hardened oil (as a softening component) which was synthesized from fatty polyamide salts. The prepared SS-5 and the PP finishing resin were applied to PP finishing cotton cloth and P/C gingham sample by one-bath method. The properties such as crease recovery, tear strength, and bending resistance were tested. The samples treated with SS-5 and PP finishing resin showed improved properties when comparing with the untreated ones, with the ones treated only with PP finishing resin, with ones treated with commercial PP finishing softners and PP finishing resin. The grades of fabric samples treated with 3% SS-5 were fifth grade in the bending resistance test.

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.

Purpose: This study was on the economic feasibility of BIPV system, focused on comparison with construction cost of BAPV system depend on roof finishing materials, and to suggest basic data on the construction cost. Method: Construction cost of BAPV system was calculated, by selecting asphalt single, flat type roof tile, color steel plate, titanium zinc plate as roof finishing material of residential building and by sum up each cost for roof finishing construction and cost for 3kWp-volumed PV module installation. Also, the economic feasibility was analysed quantitatively by comparing the cost for BIPV system construction, installing same volumed PV module instead of roof finishing materials. Result: 1. By installing BIPV system instead of the roof finishing material, the cost of construction falls ; about 19% in case of the titanium zinc plate, which is the most expensive, and about 11% in case of the color steel plate. 2. Reducing amount of the construction cost gets larger because of installing BIPV module instead of the roof finishing material, as the construction cost for roof finishing material gets higher ; therefore, it is more economical than BAPV system in terms of whole cost of construction.

공동주택의 경우 사람의 실거주 및 코어시험 시 일어나는 분진 및 소음 등으로 인하여 비파괴검사를 진행하기 어려워 공용부 및 지하 주차장에서 매번 점검이 이루어지며, 저가 수주로 인한 콘크리트 면의 실험이 아닌 마감재 위에서 실험을 진행하여 부실점검이 발생할 수 밖에 없는 실정이다. 또한 강도 추정을 위한 제안식들은 시험조건과 환경의 차이에 따라 변동폭이 크고, 동일한 측정값을 나타내더라도 제안식 마다 그 편차가 커 정확한 강도 추정이 어려워 사용에 어려움을 겪고 있는 실정이다. 이에 공동주택에 주로 사용되는 마감재를 선정하여 마감재를 제거하지 않고 직접 마감재에 비파괴검사법을 활용하여 마감재 종류에 따른 콘크리트 압축강도 비교 평가를 하고자 한다. 마감재 종류에 따른 초음파속도법을 이용한 콘크리트 추정압축강도 신뢰도 평과 결과는 다음과 같다. 초음파속도법을 통해 도출된 추정압축강도와 압축강도의 오차율은 21.83% ~58.89%로 광범위한 변동폭을 보이며. 추정압축강도에 대한 마감재 유무의 영향은 미비한 것으로 나타났다. 이에 마감재 종류를 더 선정하여 마감재 유무에 따른 초음파속도법 연구가 필요하며 신뢰도를 높일 수 있는 추정기법 연구가 필요하다.

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, another method of magnetic abrasive machining in which the N and S magnetic poles are feed and a workpiece is rotated only is tried in a fine-pipe, and its finishing characteristics is experimently investigated by various effective factors such as feeding amplitude. From the experimental results, it is found that the feed effects of magnetic poles on the finishing characteristics are large in internal finishing.

The finishing process for dies and molds is an important process because it has influence on final quality of products. And it is difficult to automatize finishing process so that the process has depended on expert's skill until now. However, recently a study on development of die automatic finishing machine has been progressed, and actually this machine is applied to fabrication of die. But the research about tooling system is not enough and finishing tool must have high machining efficiency and adaptability of curved surface. So, this study investigated the application of conductive elastic tool which is composed of metal-resin bonded pellet and elastic backing material. The metal-resin bonded pellet is used to finish the surface by conventional mechanical grinding or electro-chemial grinding method. And elastic backing material is used to follow the curved surface. So conductive elastic tool has long lifetime, uniform removal rate and adaptability of curved surface.

In this study, it is experimented to find factors effecting surface roughness using the system of experiments. in the mirror surface finishing system. (1) The film feed and oscillation frequency in $40{\mu}m$ abrasive film, grinding speed in $30{\mu}m$, and machining time in $15{\mu}m$15 are the main factors effecting the surface roughness. (2) Applying the optimal finishing condition to $40{\mu}m$, $30{\mu}m$, $15{\mu}m$ abrasive finishing film in sequence, it is possible to obtian about Ra 10 nm surface roughness on SM45C workpiece. (3) Application of the system of experments to the micro abrasive grain film finishing was very effective method in the extraction of main factor and optimal condition.

Lubricating softner(SOS-2) for permanent press(PP) finish was prepared by blending water, beef tallow hardened oil for improving softness, and the emulsion which was synthesized from N-hexadecanoyl-N,N'-bis(2-hexadecamidoethyl)amine as a softening component and silicone oil KF-96 as a lubricating component. The prepared SOS-2 and the PP finishing resin were applied to PP finishing cotton broad cloth and P/C gingham samples using one bath method. The properties such as tear strength, crease recovery, bending resistance test were tested. The samples treated with SOS-2 and PP finishing resin have improved properties, compared with nontreated samples, those treated only with PP finishing resin, those treated with commercial PP finishing softners and PP finishing resin.

Indoor air quality has attracted great attention in recent years and thus the importance of managing finishing materials in terms of pollutant source control is being emphasized. Managing the finishing material at the design stage maximizes the efficiency of IAQ control at the following construction stage. However, there are insufficient investigations on the application of a specific finishing material management process, a database management system or a finishing material management process network. As a result, the main purposes of this study comprise comprehensive evaluation of IAQ performance from the selected finishing materials and auxiliary materials, application of the material management system basing on the types and characteristics of toxic substances generated from the indoor finishing materials, investigation of IAQ evaluation standard, and the overall IAQ evaluation method for the design parts. The result of this study will be the basic data to construct DBMS for management of finishing materials with respect to IAQ.
