Recently, railway has been pointed to the efficiency of transportation, rapid transit, and comfortable train ride. the construction of railway near the downtown area and station building are increasing for maximization of utilization and convenience. but the heavy of transportation and rapid transit lead to increase noise and vibration. the noise and vibration of railway may cause the civil appeal, decline in the serviceability and insufficiency of environmental standard. Therefore, the solution to avoid environmental matters becomes one of the most important factor in constructing railway. In this study, floating slab system which is one of the solution to avoid noise and vibration in railway has been introduced, and the concept of preliminary design and vibration absorber of floating slab system according to the isolator has been introduced.

The wooden pagoda sites which have been confirmed in Baekjae's former territory so far have flattened surface of the earth or foundation pert made by digging up the earth. In particular, the latter is found more often in the pagoda sites of Baekjae, which is essential and absolutely necessary because of the characteristics of pagoda structure. The wooden pagoda sites with foundation part made by digging up the earth under the stylobate are found at Yongjeongli ruined temple site of Woongjin area, and at Neung-sa temple site, Wangheung-sa temple site, Geumgang-sa temple site, and Mireuk-sa temple site of Sabi period. They are also observed at Hwanglyong-sa nine-storied wooden pagoda of Shilla and at Biin five-storied stone pagoda of early Goryeo. They are important data improving that the construction technologies of Baekjae continued to be applied to build stone or wooden pagodas, transcending time and space. Recently, the site assumed as a wood pagoda site of Hanseong area was examined in Gyeongdang sect ion of Pungnap mud fortification. If this is proved to be a real wooden pagoda site, this digging-up construction technology of foundation part ann be concluded to be a traditional engineering technology of Baekjae which was frequently used from Hanseong period to Sabi period. On the other hand, this digging-up construction technology of foundation part has been found only at pagoda sites and main building sites of temple ruins, and it helps examine their symbolism.

Balhae(698~926) was the ancient state which opened the Nambuk-guk period with the Unified Silla. But Balhae architecture began to included in the history of Korean architecture only about 15 years ago, such as the books written by Yun Jang-seop or Ju Nam-cheol. I discussed four issues related to Balhae architecture in this paper. First, I criticized the excavation report of 24 stones remains at Jiangdong in Duhua city, and I asserted the ondol site belonged to different period. Second, I also interpreted that the building found on the tombs no.13 and no.14, in the Longhai burial area in Helong city must be a wooden stupa. Third, Balhae played some important roles in the history of ondol. It developed Koguryeo ondol in terms of structure, gave an opportunity to the ruling class to adopt ondol for the first time, and passed the heating system down to the Jurchen, the ancestor of the modern Manchurian. Fourth, the Russian-Korean joint research team excavated seven building sites in Koksharovka 1 fortress from Russian territory these four years, and it is reasonable to assume the fortress was the center of Anbyeon-bu, one of 15 local government districts in Balhae. I guess this buildings were the royal shrine built by resisters after the fall of Balhae, and the vessel stands found there must be used for ancestral memorial ceremony inside them.

The core strategy of transit oriented development (TOD) is to promote high density mixed land use around railway stations. Case studies in advanced countries show that provision of policies for comprehensive maintenance of pedestrian facilities around railway station spheres is being pursued with efficacy. In spite of the importance placed on integrated pedestrian maintenance, domestic construction of integrated pedestrian infrastructure around railway station spheres lacks direction. Thus, there is a clear need for an evaluation standard that can provide the foundation for judgments on TOD improvement. This research proposes a network model that consolidates the interior of the station as well as its surrounding areas to determine the ease of pedestrian flow for effective TOD evaluation. The model considers the railway station and surrounding areas as an assembled network of pedestrian flow. The path chosen by the pedestrian is defined as the optimal degree of inconvenience, and expands on Wardrop's User Equilibrium (1952). To assess the various circumstances that arise on pedestrian facilities including congestion of the pedestrian pathway, constrained elevator capacity, and wait at the crosswalk, a variational inequality based pedestrian equilibrium distribution model is introduced.

The purpose of this study was to understand changes in Seoul's downtown planning from the 1960s to 1990s. The approach was examined by classifying its formation process though urban conservation. The effects of modernization and urbanization on Seoul's downtown planning were as follows. In the 1960s, Seoul attempted to decentralize urban functions due to excessive population. In the 1970s, a policy to diversify urban functions according to Gangnam development was enacted. In the 1980s, the existing downtown declined, and the sub-downtown grew with changing urban functions. In the 1990s, the identity of the existing downtown was recognized through the Seoul Memorial Project. This study also analyzed downtown planning efforts concerned with urban conservation. First, the physical aspects of existing buildings and street facilities were maintained. Second, the spatial aspects for the maintenance of surrounding areas were proposed. Fourth, the social aspects for accessibility by Seoul citizens was improved. This analysis demonstrates the concept of urban conservation based on physical-spatial-social aspects.

Studies and reports on buddhist temples in Goryeo dynasty are rarely In the present situation. At this point of time new excavational reports and historic records offer many materials to understand a architecture in Goryeo period. Especially, temple site have various transitions, it is of great value to study. This article attempted a restorative study of a location, function, spacial arrangement, structure, building age is based on a measure and transition of temple layout that is based on the excavational result and related historic documents about Godal temple site in Yeoju. Gadal temple site was a representative Zen buddhist temple in Goryeo Dynasty. It was difficult of access by watercourse because it was located in an inland in the upper Han River. Archaeological research and historical records has reveals that the temple was constructed with a minium of four levels[six terms]. We could recognized the central site of temple and buildings were constantly established, enovated or collapsed. It has went through many transition according as it encountered new sects and doctrines. Also it should perform various functions and overcome given conditions. Ultimately it let see greater diversity in the spacial composition, and layout. That is to say it were planed several separate areas, each was consisted of main buildings, once again was integrated into one temple.

This article intends to shed a light on the British architect Arthur S. Dixon (1856-1929). He is largely regarded as a pioneer of the English Art and Craft Movement, yet his works are not widely known nor carefully studied. In search of Dixon's architectural characteristics, this paper examined three notable buildings that he designed at the turn of the nineteenth century; Birmingham Guildhall, St. Andrews church and St. Basil's Church. These buildings were erected relatively early in his career as an architect, although he never fully immersed into the profession due to his commitment in family business management. His architectural design shows unique qualities of Art and Craft movement in terms of use of material, spatial arrangement, techniques, and craftsmanship while employing Romanesque as most relevant historic style for ecclesiastical purposes.

Ijidang(二止堂) is a private village school (seodang, 書堂) established in Okcheon, north Chungcheong province where Jungbong Jo, Heon(重峯 趙憲, 1544-1592 AD) had trained for his sound mind and body(yusangcheo, 遊賞處). Jo, Heon was a notable Neo-Confucian scholar of the Kiho School and also a righteous general leading soldiers in Joseon Dynasty. According to Ijidanggi(二止堂記), Ijidang was constructed to honor Jo, Heon and to train local talents in 1647 with the support of Song, Si-yeol(宋時烈, 1607-1689 AD),a representative scholar belong to Kiho School and other local Confucian scholars. Ijidang currently consists of Main Body(本體) in the middle along with the East(Dong-lu 東樓) and the West Pavilions(Seo-lu 西樓) attached to each side. The Main Body and the Dong-lu firstly constructed were to give lectures and to rest within. Ijidang has undergone several changes in its form so far. The surrounding nearby Ijidang shows characteristics of the Confucian architecture for training(J eong-sa, 精舍) and the building itself was to be built in a scenic place apart from the secular world in which scholars stayed, cultivated their body and mind or taught disciples within. The lecture space of Ijidang is positioned next to the main hall(Dae-cheong 大廳) unlike other typical forms of a three-bay building(samganjije 三間之制) at that period. West lu, a two-story building added afterwards in the early 18th century representing characteristics of the Gate Pavilion(Mullu, 門樓) of Neo-Confucian Academies(Seo-won, 書院) in Joseon Dynasty was typically located where the entrance and the ground floor of the main building are visible simultaneously.

A hundred wooden foundation piles were found underground during reconstruction for Heungreamun after removing ex-Chosunchongdokbu (ex-Government General of Chosun) building, which was built in 1916, at Kyungbok Palace in Seoul. It is known that larch piles had been collected from the Yaru area near Mt. Baekdu (Changbai). in North Korea. We examined 15 piles for identification of the species and their tree-ring structure. The species is identified as Larix gmelini by microscopic observation. Average diameter of the piles was 27 cm and average age 103 years. We obtained 151 year tree-ring chronology. However, we could not date the exact cutting years because there was no reference chronology yet. When we can obtain chronologies from living trees near the Yaru area, we could make a absolute and longer chronology for studying past history and environments around Mt. Baekdu.

The purpose of this study is a suggestion which is a way for preservation and management the Jongmyo landscape based on its landscape visibility and land use. To do this, we had done a field investigation and a literature examination. The investigations are as following; we researched current application which for changing the actual condition near the Jongmyo. According to this research site could notice that landscape visibility can be affected by not only the height of building the Jongmyo. The visibility can be affected by photograph's undulation, too. Furthermore, we notice that even some building are located far from the view point and view corridor, it can be a factor which decrease the quality of the landscape visibility. Finally, we can propose how to make way for conservation and management by through restrict land use which based on changing the actual condition, landscape visibility and land use around the cultural assets.
