Recently, prepackaged-type surface preparation materials using redispersible polymer powders are widely used for interior and exterior finishing in the construction work. The purpose of this study is to evaluate the performance and the quality of prepackaged-type surface preparation materials using a VA/E/MMA terpolymer powder. Surface preparation materials using a VA/E/MMA terpolymer powder were prepared with shrinkage reducing agent contents of 0, 4 % and cellulose fiber contents of 0, 0.5, 1.0 %, and tested for drying shrinkage, strengths, adhesion in tension, crack and impact resistance, water absorption, permeability. As a result, prepackaged-type surface preparation materials show outstanding performance depending on the shrinkage reducing agent and cellulose fiber contents.

The indoor air quality of modern people who work indoors more than 80 percent a day has also become a very important factor in their lives. But most indoor air quality is highly polluted due to energy conservation and lack of ventilation. This can lead to pneumonia, asthma and even lung cancer, which can be fatal to children, the elderly and the elderly. Indoor pollutants are caused by boards, wallpaper, paint, etc. used in interior By producing indoor finishing materials using active alumina gel, which is used as dehumidifier, indoor pollutants will be reduced and the possibility of developing respiratory diseases and lung cancer will be reduced.

한국유행색산업협회에서는 1997년 국내 패션업계를 비롯하여 디자인 전반에서 사용할 수 있는 활용색 모음 제작인 COS칼라시스템을 개발하였다. 본 연구는 이 COS 칼라 시스템이 실내디자인 분야에 있어 활용될 수 있는지를 실내마감재 측색을 통해 실증적으로 검증해 보고자 하였다. 또한 실내 디자인 분야에서 표준화된 상용색 표집으로서 활용될 수 있도록 실내색채 중 COS에 포함시켜야 할 색채의 범위를 제안하고자 하였다. 실내마감재의 측색결과, 목재나 석재 등의 자연소재에서 나타나는 YR 및 Y계열의 고명도, 저채도의 색들이 많이 나타났는데, COS는 이러한 계통의 다양한 색들을 포함하고 있지 않았다. 반면, NCS는 천연 소재 및 그 대용품에서 볼 수 있는 색들을 매우 다양하게 포함하고 있어 COS에 비해 실내 색채를 표현하기에 용이했다. 그러므로 COS가 섬유패션분야 뿐만 아니라 실내디자인 분야에서 환경색채를 계획, 평가하고자 할 때 유용한 도구로 활용되기 위해서는 실내 색채의 범위를 모두 포함한 환경색채용 COS가 추가로 개발되어야 할 것이다. COS에 포함되어 있지 않은 색들을 NCS 체계로 파악하여 색상, 명도, 채도 순으로 나열하여 보면, 색상의 경우 노랑색 계열(Y, YR), 녹색계열(GY), 청색계열(PB, B, BG) 등이 많았으며, 명도의 경우에는 6-9.5와 같이 밝고, 채도에 있어서는 1-4 정도의 저채도의 색채가 유난히 부족하였다. 이와 같이 실내디자인 분야에서는 다양한 실내색채들이 추가로 파악되었으며, 이러한 범위의 색들을 앞으로의 COS에 추가되어야 할 색채의 범위로 제안하였다.

Modular construction is attracting attention as the solution of recent problems in construction site. Such as lack of construction workforce, increasing labor costs, work delay due to extreme weather events and strengthening government regulations. However, despite the many advantages, Modular construction has not been activated dueto high construction costs compared to other construction methods. Accordingly, the object of this study is priority derivation of prefabricated house cost reduction factors and use as basic research data. For research performance, we have analyzed the blueprint and bill of quantities of a modular construction based public dormitory which was built in 2013. In result, the proportion of modular construction and on-site construction is 66% and 34%, and the construction cost proportion by activity was devided in to construction(79%), machinery(7%), electricity(5%) and civil(9%). Among these results in order to reduce costs, interior finishing(19.4) steel-frame(16.9%), metal works(13.5%), RC(11.8%), joinery(7.3%) is the order requires focused management.

The purpose of this study is to conduct a comparative analysis between Korea and the United States of the supply process of unit modular housing at both the factory production phase and the transportation and lifting phase, as part of an attempt to invigorate the unit modular housing market in Korea. Unlike the practice in the United States, one of Korea's unique characteristics is that the floor is constructed with reinforced concrete and hot water heating system. To do this, the wet method in Korea is used that includes concrete placement, curing and constructing hot water floor heating system at the factory production phase, which results in a longer production time and also requires the lifting of heavier loads. In the United States, interior and exterior finishing works of modular housing are performed by different companies, and the distance between the unit module factory and the construction site is quite far. This kind of dualized production structure may cause confusion when it comes to schedule management, procurement management, and stock management. Moreover, problems caused by external environmental factors such as wind and rainfall were reported in the course of long-distance transportation. The results of this case comparison are expected to provide fundamental data that will reduce the amount of trial and error in the unit module production, transportation and lifting work in Korea, which has a comparatively small number of unit modular housing cases.

This study attempted to identify the characteristics of chair design from furniture company, $K{\ddot{a}}llemo$, the furniture manufacturer in Sweden manufacturing mostly the limited edition of art furniture on the basis of the unique management philosophy. There are 12 artists manufactured chairs for $K{\ddot{a}}llemo$. Of them, this study selected 4 artists-Sigurdur Gustafsson, John Kandell, Komplot Design, Mats Theselius-who designed at least more than three chairs. Total 25 chairs were analyzed; 6 from Sigurdur Gustafsson, 8 from John Kandell, 3 from Komplot Design and 8 from Mats Theselius. The chair structure was divided into three parts, seat, back and structure and analyzed by material, color, type of legs and finishing. The following results were derived from the study. First, $K{\ddot{a}}llemo$ secured the regular customers who want to possess the chairs as the artistic works by continuing the small quantity mass-production system insisting that the maximum quantity of production is 360 pieces and the minimum quantity is 33 pieces. Second, the sufficient time and cost were invested in the initial phase of design. This approach seems to be deviated from the traditional business system that has to create the revenue at a glance, but ultimately induces the commercial success by exponentially increasing the revenue through the creation of various product lines. Third, $K{\ddot{a}}llemo$ provides the space that the artists who work for $K{\ddot{a}}llemo$ can sufficiently enjoy the mental composure and luxury required for the designers by strictly selecting the artists and providing the best environment for enabling the creative activities that look like the pure art area. This study enables the further analysis and research on other collections of $K{\ddot{a}}llemo$ that mass-produces the chairs on the basis of the unique philosophy in the world as well as in Sweden using more various kinds of analysis frameworks.

BIM은 단일모델을 이용해 다양한 시나리오로 활용 가능하다는 이점이 있다. BIM 모델을 통해 2D 도면을 자동으로 추출하는 점도 그 중의 하나이나, 이를 실무에서 그대로 활용하기에는 현실적으로 어려움이 따른다. 건축 상세도면은 실내재료 마감 및 복잡한 시공방법을 표현할 뿐 아니라 공사비 산정에 있어 매우 중요한 요소이다. 하지만 이를 BIM 환경에서 표현하는 공통적인 규칙이나 약속이 없고, 설계사별로 같은 의미의 상세도면을 각기 다른 형태로 보유하고 있어 건설산업차원에서의 정보공유 및 교환을 어렵게 한다. 따라서 본 연구에서는 건축 상세도면의 BIM 활용을 위해 부분상세 정보를 체계화하는 방법을 제시하고, BIM 라이브러리와 어떻게 연계되어 수량 및 공사비 산정의 기초자료로 활용되는지 파악한다. 본 연구는 건축 설계자가 설계 업무 진행시 BIM 라이브러리를 통하여 부분상세정보를 확인하고 단가정보, 자재정보 등과 연계되어 수량 및 공사비를 산출하는데 활용될 수 있다. 또한 BIM 라이브러리-기술콘텐츠 연계기술로 인해 BIM기반의 설계효율과 프로세스를 개선해 중소설계사무소의 효율적인 BIM 활용에 도움이 될 것이다.
