It is not uncommon in Korea to see the structure and function of a garden remain intact as well as its form. Yi Cheon-bo's Historic House (Gyeonggi-do Cultural Heritage Item No. 55), located in Sang-myeon, Gapyeong-gun, Gyeonggi-do, is considered an example of very valuable garden heritage, although its family history, location, and remaining buildings and natural cultural assets are not fully intact. Along with Yi Cheon-bo's Historic House, this study attempted to explore the possibility of restoration of the forest houses and gardens by highlighting the high value of Yi Cheon-bo's Historic House through research into the typical layout of private households in northern Gyeonggi Province and Gapyeong County, comparative review of aerial photographs from 1954, and interviews with those involved. The results of the study are as follows: In this study, the presence of Banggye-dongmun and Bansukam in the Banggyecheon area, where the location of the garden was well-preserved, was examined across the landscape of the outer garden, while the location of Yi Cheon-bo's Historic House, the appearance of feng shui, and the viewing axis were considered. Also, the appearance of the lost main house was inferred from the arrangement and shape of the Sarangchae and Haengrangchae that remain in the original garden, and the asymmetry of the Sarangchae Numaru and the hapgak shape on the side of the roof. In addition, the three tablets (Pyeonaeks) of Sanggodang (尙古堂), Bangyejeongsa (磻溪精舍), and Okgyeongsanbang (玉聲山房) were used to infer the landscape, use, and symbolism of the men's quarters. Also, a survey was conducted on the trees that existed or existed in the high prices. Incidentally, it was confirmed that information on boards and cultural properties of Yeonha-ri juniper (Gyeonggi-do Monument No. 61) was recorded to a much lesser extent than the actual required standard, and the juniper trees remaining in the front of Haengrangchae should also be re-evaluated after speculation. On the other hand, as a result of estimating the original shape as a way of pursuing completeness of the garden through restoration of the lost women's quarters and shrine, it is estimated that the main house was placed in the form of a '口' or a 'be warped 口' on the right (north) side of the men's quarters. By synthesizing these results, a restoration alternative for Yi Cheon-bo's Historic House was suggested.

Asan Oeam village is a town that has been formed since about 500 years ago. It is a folk village centered on Yean Lee and designated as National Folk Cultural Property No. 236. However, the original shape of the thatch, which has regional characteristics, is disappearing. Therefore, I want to study the architectural characteristics of the house which is well preserved in the original shape. The Genjaegotaek is located in the center of the Oeam village. The composition of the house consists of a Munganchae, Salangchae, Anchae, Sadang. The Anchae is an 'ㄱ' shaped house, and it is shaped like a 'ㅁ' which is opened by facing. The wide yard in front of the Salangchae is made of strangely shaped rocks, a hundred-year-old pine, old pagodas, ponds, pavilion. Outside the main gate, there is an 'ㅡ' shape thatch on the west. The Galabjib of Geonjaegotaek is a servant house, and the shape is a ㄱ type. The plane remained well in its original shape, thatch is consisting of a kitchen-room-daecheong maru-room. A Galabjib of Geonjaegotaek can not represent all the thatch of a Oeam village. However, it is expected that this study will be used as a basic data when the study by the thatch in this area is conducted through the analysis of the type.

The paper studies on the site and space composition of Lee Ha-Bock's traditional thatched roof house. The house is located at a site with back to the mountain and facing the water and the rear and front mountains formulate a shape of Myungeonhyung(a sleeping dog figure) with HyungGug theory of Pungsu. The house has ㄱ shaped Anchae, ㅡ shaped Sarangchae and Gwangchae. Those are formulate ㅁ lay out followed the land form. Through the research I found the house shows a typical traditional farmhouse in the middle of Korea of Josen period. Nowadays there are many large Giwajip(tile roofed house) of Josen period is remained but only a few thatched-roof house is lived. In this situation, the house has considerable architectural values as a traditional thatched roof house.

To enhance the nutritional quality of the Soboru bread, a dietary fibers extracted from Kombu was added into wheat flour in the amounts of 0, 1, 3, and 5% and the quality of the baked products was characterized. The inherent water holding capacity of the added dietary fibers raised weight of the bread while specific volume and density values were decreased at the same time. Increasing the amount of dietary fiber resulted in the decreased setback time of the raw materials in amylogram. The lower textural hardness of the dietary fiber-enriched bread after one-day storage at room temperature could be attributed to the retarded retrogradation of the starch. Darkened surface of the bread as indicated by the Hunter colorimetric values and the accompanied change in flavor did not significantly influence the sensory evaluation of the products. Judging from texture, taste and overall acceptability of the product, recommended substitution level for the dietary fiber in Soboru bread was 3% or less. Increased intake of the dietary fibers, accompained with more use of seaweed, was expected through the suggested functional bread.

Vibration isolation equipments are mostly required in precise measurement and manufacturing system. Among all the vibration isolation system, air-spring is the most widely used equipment because of low resonant frequency and high damping ratio. In this study, Takagi-Sugeno fuzzy method is used to design an active vibration isolation system using air-spring, and compared the fuzzy method with passive control method and PID control method. Due to the non-linearity characteristics of air-spring, fuzzy controller was verified to be the most effective both in simulation and experiment.

Vibration isolation tables are mostly required in precise measurement and manufacturing system. Among the vibration isolation tables, an air spring is the most favorable equipment because of low resonant frequency and high damping ratio. However, it is difficult to design the air spring with the required stiffness and damping ratio. Futhermore, whenever conventional active control methods are applied to the air spring, it may be difficult to obtain effective control performance due to high nonlinearity of air spring. In this paper, the optimal design of the air spring is performed using genetic algorithm to bring out low resonant frequency and high damping ratio. Also, active control of the vibration isolation table with 3-DOF model is proposed using the adaptive control method. Through experiments, optimal design is shown to be effective. And performance of the proposed control method is verified to be better than those of the passive control method and the conventional active control methods.

'Movement System' is made of the interaction of user and architectural spaces related to each other in order. 'Movement' meant in movement system is possible only in the status of user and architectural space together. Movement created and disappeared by the user is not subordinated to the existing architectural space but becomes the main element of formating movement system. It is required that movement conception applied to architecture should be derived from the essence of movement and this study presents the movement system. To explain the formating process of movement system, A. N. Whitehead's process philosophy theory is at the basis and transformed in architectural aspects. On basis of these theoretical backgrounds, the process of making movement system can be explained. There are unit movement, unit object, and elements for movement process as the basic requirements for movement system, each unit is apprehended by individual operation and the nexus is composed by associative operation of apprehended units. This nexus becomes the object of a new subject and forms multiple nexus. Relation of unit movement and unit object and nexus are apprehended as the continuation and extensive continuum is made. At that time, movement with multiple phases set inbetween systems and extended multiplied. Through above study, movement system is applied to Korean traditional houses.

In recent days, vibration isolation system is mostly required in precise measurement and manufacturing system to reduce vibration due to external disturbances and internal actuators. Among all the vibration isolation systems, air spring is widely used because of its low resonant frequency and high damping ratio. In this study, we first analyze the passive air-spring system using leveling valve, and then design the active vibration isolation system. Because the non-linearity of pneumatic characteristics, we try to design the fuzzy controller which is better than PID controller at complex and non-linear system, and then compare them both in experiment and simulation.
