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.

With evolution in the production environment of the textile industry, the need for non-water-based dyeing technologies and eco-friendly process facilities in the dyeing and processing stages has increased. In recent years, supercritical fluid dyes have been developed and commercialized in Europe, centering on this demand. However, so far, such dyes have been mainly applied in the processing of PET fibers. Basic research has mainly involved investigation of dyeing by supercritical carbon dioxide or solubility of such dyes, and more in-depth research should be continuously carried out. In this review, we describe the types and characteristics of supercritical fluids that exhibit specific properties at pressures and temperatures over the critical point. In addition, the state of the art in the dyeing and processing technology using supercritical fluids and associated, processing problems, environmental regulation, and wastewater treatment issues are described in detail. We hope this review can contribute to the supercritical fluid technology being further developed as an environment friendly dyeing processing method. Furthermore, we expect that the technique can be used as a means of ensuring different, high-quality dyed products.

The stylobate for expanding the external stage area was the most frequently installed installment out of the installments installed for royal court ceremonies. The stylobate was installed for various ceremonies such as funeral rites, ancestral rites, customary formalities, state examination, feasts for celebrating a honored guest of the court, queen's silkworm cultivating ceremony, heir appointment, the presentation of honorary titles for the king or queen in honor of their merits, and entertainment of foreign dignitaries. The exact period stylobates came to be used for the play stage. The stylobate consists of the 紅座板, 屯太木, 竹欄間, 足木, and the 層橋. Depending on the 足木, the substructure of the stylobate, the stylobate could be divided into the 長足木, 中足木, 短足木, 平足木 type. The detail structure of the stylobate changed in form from the jokmok and duntaemok that appeared until the time of King Seonjo, into the 長屯太木, 短屯太木, and the 短短屯太木 during the time of King Heonjong. With the introduction of the 中足木, materials began to become more segmented and the structure stronger. According to existing records, while the height of the stylobate was not significantly high prior to King Seonjo's reign, the 十四層雲橋 and the 十三層層橋 introduced during the time of Emperor Gojong was designed to reflect his rank in external ceremonies while the eight story step bridge was exhibited in internal ceremonies to reflect the rank of Queen Mother Sinjeong. From here, we can deduce that the fourteen and thirteen story cloud bridges representing the king was of a higher grade than the eight story step bridge which represented the queen mother. Finishing by adding boards to the lower part of the stylobates began to appear in the time of King Seonjo. During King Heonjong's reign, the lower finish became gentrified with a thin board called 修粧板, and yeomupan 廉隅板 for decorating the edges of the stylobates were installed. Such style of finishing the lower part of the stylobate with boards mostly appeared in elaborate feasts 進饌 and celebrations 進宴 within the royal court 內宴. The stylobates appeared to have served not only practical purposes such as expanding the stage area, but also as installments which realize the authority and prestige of the royal crown. They were installed according to the purpose of the ceremony and the rank of the participant. In short, stylobates became established during King Seonjo's reign, became segmented and gentrified during King Heonjong's reign, and began to take height variations during Emperor Gojong's reign to reflect the rank and authority of the king and queen mother. As such, it can be considered another characteristic of Joseon Dynasty architecture.
