Considering the established research about the characteristics of traditional expression in a contemporary korean architecture, there are two critical problems. the one is that the extent of a case is limited to a public building and a large exhibition building. the other is that the angle of research focus on the viewpoint of specific a level. To settle these problems and supplement a established research, this study is to investigate and analyze the characteristics of popular traditional expression in small commercial buildings. In A viewpoint on the expansion of a case and a various angle, A small commercial buildings is selected as a case. because it is felt that the populace's taste vis-a-vis traditional expression. To investigate and analyze, A main analytic criterion is follows. 1) A expressional method on traditional architectural form 2) A expressional aspect by architectural element 3) A expressional aspect in architectural material 4) A expressional aspect in architectural structure. In consequence we can find out the following results in the process of analysis. 1) In expressional method on traditional architectural form, the traditional expression is represented as the imitation and transformation of a traditional folk house forms, and the embodiment of traditional image 2) In expressional aspect by architectural element, the traditional expression elements is mainly represented at a straw roof and a mud-plastered wall 3) the traditional expression material is mainly straw, timber, small wood boards and mud 4) In expressional aspect in architectural structure, the traditional expression is represented from the viewpoint of decorative expression.

In the study the documents in Ryu Hee-Choon's diary (Miahm-Ilgicho) from Oct. 29th 1575 to Feb. 9th 1577, for Kaeg-Chung(客聽) are arranged and analized. Ryu, Hee-Choon (Mi-ahm) was a civil minister in the era of Myung-Jong to Sun-Jo of the Chosun dinasty. This study would be one of the basal material for actually inquiring into the character of houses for the gentry in the late 16th century. Above all, the significance of this is that it study could show the details of the architectural economy, the organization of architectural society and the process of the supply of architectural material at that time. Craftsmen devoting themselves to this work are carpenters, artisans making roof titles, roofers and artisans constructing walls. And the content that are craftsmen of monks(僧匠), artisans of commoners(私匠) and slaves belong to government(官奴) is noticeable thing. In this construction work, monks in temples of the region and laboures commandeered by the government office are mainly mobilized. Except of them, private slaves and commoners mobilized by government office also devoted themselves to this work. But, it required more research whether this aspect could be the general character of the construction work of the gentry in the late 16th century. Architectural material, in the case of wood was cut and transported mostly from islands like Jin-do by labourers commandeered by the head officer of the region and monks. Superintendents seemed to come be non-specialists of noble families of the ruling class. So, it is thought that they managed mainly the manpower supply and administration. And some architectural ironworks, much provisions and marine products for labourers and craftsmen were proided by the government office of the region. This could be understood in the same context as above that goverment office of the region contributed to commandeering labourers and supplying architectural material in some degree. Carpenters and roofers took wages that is, about 7.7 pils(匹) of cotton cloth for each carpenter and 5 pils of cotton cloth and some provisions for each roofer. This would be a noticeable thing for researching wages of craftsmen at that time

The starting point of this study is the concerning of simple behavioral pattern that whoever enters the inner space with taking off his shoes should go out from the position where he laid his shoes. The using of Ondol (floor heating room) and Maru (lifted wood floor) had changed the architectural space from chair-sitting to floor-sitting space, and it also made the behavior of taking off the shoes at the entrance of building and stepping on the lifted floor. This simple behavior has possibility to make lots of changes to the culture of architectural design. With this noticeable point, this paper is talking about the cultural feature of Korean traditional architecture, especially about the influence of tanking off and putting on shoes. The matter of shoes has changed diverse aspects of building and layout planning. It maximized the difference between front and rear part of building and characterized the lateral extension of Korean traditional house. The ritual space also had evolved from chair-sitting to floor-sitting space according to the type of ritual behavioral pattern. The change on the single building level had influenced on the layout planning of architectural complex. For examples, the parallel layout of ChangDeok-gung palace and the long sequential process to the main pavilion of Buddhist temple are the result of the matter of shoes. And NuGak(樓閣), the double-storied pavilion, on the axis of entering sequence's node is one of the unique planning elements that makes possible to go through the building without taking off the shoes and also makes upper level space for staying. In short, Korean traditional architecture that has the chair-sitting spatial origin of the East Asian cultural sphere has pursued new architectural issues and planning methods according to evolution to the floor-sitting culture.

The reduction of the energy consumption in papermaking process become more important issue because of the regulation of green house gas (GHG) emission. Since more than half of energy for papermaking process is consumed during drying process, the increase of the drying efficiency would be very important solution for saving energy and reduction of GHG emission. The improvement of drying efficiency could be very difficult for the liner board mill because the liner board are usually made of recycled paper, OCC (old corrugated container). The short fiber and fines originated the OCC lead to compact sheet structure and delay the water flow out during wet pressing process and drying process. The application of lignocellulose spacer could provide more loose wet sheet structure and result in the higher drainage rate and the improved drying efficiency. In this study, the effects of the application of lignocellulose spacer to the liner board mill were evaluated based on the mill trial. In order to overcome the common disadvantage of the spacer, the loss of strength properties, the spacer was pretreated with amphoteric polyelectrolyte during mill trial. The results showed the application of pretreated spacer improved the drying efficiency by reducing steam consumption. And the loss in the strength properties by the spacer could be supplemented by the pretreatment.

Formaldehyde(HCHO) and total volatile organic compounds(VOCs) can cause adverse health effects to the building occupants and may contribute to symptoms of 'Sick Building Syndrome'. These chemical contaminants are emitted from furnishings and electronic equipments as well as building materials. The purpose of this study is to measure and analyze VOCs and HCHO emission concentration from furnitures composed of wood materials including various chemicals by the large chamber method. This paper presents experiment results on the emission concentration of TVOCs and HCHO released from furnitures, such as bed, kitchen, sofa and table by a large chamber($24m^3$). The temperature and air humidity in the chamber are controlled to $25{\pm}1{\circ}C$ and $50{\pm}5%$ for this experiment. When the air change rate is $0.5hr^{-1}$, the background concentrations within the large chamber are below $50{\mu}g/m^3$ for TVOC, $5{\mu}g/m^3$ for HCHO and individual VOCs. The study is investigated the characterization of the chemical emission TVOC and HCHO concentrations and unknown VOCs from 6 furnitures.

Korean traditional architecture has been carried out in the manner that it harmonized surrounding natural environments and never disturbed them in the scale which did not overwhelm the nature, based on the view of architecture predicated on Yin Yang School. The exposed grain of the wood like pillar, hinge and house rafte, the linear expression of the construction material and the formation between the window and door monopolizing the front side presented a harmony with the nature showing the linear structure. Furthermore the ceiling is low due to the sit life style thanks to the ondol (Korean under-floor heating system and the furniture was made in simple manner to utilize the space as large as possible, for the interior was narrow and close, and also the furniture placing in the middle of the room was movably manufactured to improve the room space. Like this Korean traditional furniture was close associated with the low height and simplicity and harmonized with the blank of the wall accordingly, and it characterized linear & planar natural beauty focusing on the simple and refined unique beauty, because it was made in a good harmony with the interior utensils. This study has presented that the organic characteristics of Korean traditional aesthetic of architecture and the natural beauty being intrinsic in traditional furniture have a mutual relation on the basis of not only the visual recognition, also the aesthetic of naturalism made of the natural material, the constructional naivety as a frame method and the linear & planar formative beauty shown in appearance.

본 연구는 이동식 정자의 설계시공방법을 살펴보고자 문헌분석을 통해 조영 배경과 입지와 향의 설정, 규모와 구성, 재료, 시공방법 등을 분석함으로써 다음과 같은 결과를 도출하였다. 첫째, 이동식 정자는 곳곳에 펼쳐진 경승을 두루 유람하기 위해 고안된 정자로 산수를 즐기는 경험을 바탕으로 자신의 집을 소유하고 정자를 경영하는 것보다 이상적인 삶을 추구하는 방식이 반영된 창작물이었다. 둘째, 이동식 정자의 조영은 계절별, 시기별 경관을 때와 장소의 제한 없이 감상하고자 하는 의도로 조성되었으며. 풍류를 즐기기 위한 도구를 매번 옮겨야 하는 번거로움을 해소하고자 고안되었다. 셋째, 이동식 정자는 경관을 조망하기 용이한 곳을 향하여 입지와 향이 결정되며, 대부분 소규모로 조성되어 그 안에서 경관을 감상하거나, 바둑, 작시, 탄금 등을 위한 공간을 구분하였다. 또한 목재를 주로 사용하고, 하중을 저감시키기 위해 대나무나 짚, 유둔, 면포 등 가벼운 소재로 지붕과 벽면을 구성하였다. 시공방식은 결합과 해체가 용이하도록 하는 결구기법이 주로 사용되었으며, 선박이나 수레 상부에 정자를 조성할 경우에는 일반 정자의 목구조식 시공이 이루어졌다. 넷째, 일반 정자와 이동식 정자의 설계시공 특성을 비교해보면 이동식 정자는 조영목적상 경관의 관람이 용이하여 입지와 향의 설정에 제한이 없으나, 기동력을 고려하고, 구조적으로 하중을 견디기 위한 방안이 마련되어야 하며, 정자로서의 기능과 형태를 만족시켜야 하기 때문에 보다 엄격한 제도와 기법이 요구되었다.

본 연구는 조경전문잡지인 '환경과 조경'의 광고 내용 분석을 통해 조경산업의 전반적인 구조를 알아보고 조경시설물의 변화 및 요인을 분석하였다. 이를 바탕으로 향후 조경시설물 행보의 방향제시 및 기초자료로 제시하고자 하였다. '환경과 조경' 창간호부터 30년 간 게재된 광고를 분석한 결과 옥외시설물이 1,853회의 빈도수를 보이고 있으며 이중 휴게시설이 1,475회, 편익시설이 378회로 나타났다. 옥외시설물의 광고 빈도수가 다른 조경시설물에 비해 월등히 광고 빈도가 높은 이유에는 주택건설 관련 정부정책의 영향을 많이 받았으며, 공공디자인으로의 업역 확장과 더불어 휴게시설물 시장의 확대에 연유함을 알 수 있었다. 또한 휴게시설물의 주요 재료에는 퍼걸러와 벤치 모두 목재와 철재가 대부분을 차지하고 있었으며 퍼걸러의 경우 지붕재의 종류로 경제적 측면과 내구성 측면을 고려한 폴리카보네이트가 가장 많이 사용되었다. 조경분야의 대표 잡지에 실린 광고를 대상으로 조경시설물의 흐름을 통시적으로 분석하여 시대별 동향, 시설물 유형별 디테일 변화를 파악하고자 하였다.
