The tradition of architecture in the East and the West are different in many ways. One of the basic cause of such difference, however, is the different ways of perception of space and time. This paper aims to identify the attitude of perception of space and time in the cultures of the East and the West, and its influence on architecture. Degrees of importance placed on either space or time, as well as the modes of perception of space and time are discussed in relation to architecture. Basically, the architecture of the West seems to be more spatially oriented than the East, and this have much to do with the fact that the tradition of Western architecture is visually oriented. On the other hand, East Asian architecture have been more conscious on bodily feeling and its movement in architecture. Spatial units of traditional Eastern architecture, are arranged in such a way in which man can experience the change of space that is supposed to be organized to form a sequential message. Thus, in the East, temporal dimension is more deliberately included in the course of architectural experience compared to the cases of the West. Although it is not easy to attempt any kind of value judgment on such aspects, it is necessary to understand how the different perception of space and time influenced architectural outcome, especially when one wants to understand the cultural cause that have made the architectures of the East and the West very different. Such understanding is particularly important in East Asia where their future of architecture depends much on how they harmonize the Eastern and Western background which are already built up as two cultural structure in their consciousness to be able to create more desirable architecture for themselves.

This paper presents experimental results on the behaviour and ultimate load of fifteen pipes and six roof panels made of ferrocement. Additional results from three roof panels, carried out by others, are also compared with this research results. OPC cement, natural sand and galvanised iron wire mesh were used for the construction of 20 mm thick specimens. The pipe length was 2 m and roof panel length was 2.1 m. The main variables studied were the number of wire mesh layers which were 1, 2, 3, 4 and 6 layers, the inner pipe diameter which were 105, 210 and 315 mm, cross sectional shape of the panel which were channel and box sections and the depth of the edge beam which were 95 mm and 50 mm. All specimens were simply supported and tested for pure bending with test span of 600 mm at mid-span. Tests revealed that increasing the number of wire mesh layers increases the flexural strength and stiffness. Increasing the pipe diameter or depth of edge beam of the panel increases the cracking and ultimate moments. The change in the pipe diameter led to larger effect on ultimate moment than the effect of change in the number of wire mesh layers. The box section showed behaviour and strength similar to that of the channel with same depth and number of wire mesh layers.

This study explores changes of industrial scales and building activities in the semi-industrial area of Seoul's Seong-su, responding to the shifts of industrial structures and policies in the Korean society. The purpose of this study is to investigate patterns of construction activities of factory buildings in the Seong-su semi-industrial area by analyzing changes in industrial facilities. As a result of the analysis, the change of the factory building area come out from the recent survey implies the possibility of entrepreneurial inflow as much and the new constructions and some remodeling cases which are characterized by complexity seem to correspond to the industrial structure. However, it is unreasonable to believe that this phenomenon is a mainstream movement involving small-scale factory buildings and companies. This is because there are aspects that are not included in this movement, such as changing the use of buildings without accompanying physical changes. On the other hand, compared to various movements of individual companies in response to the industrial structure, the physical plan suggests a limited alternative centering on the floor area ratio and the building area ratio. This means that the efforts to attract and grow the power of knowledge based-industry through the designation of the Industrial Development Promotion District in part of the case sites, overlook the natural change through remodeling and reuse of existing buildings. In addition, considering the fact that the production space of industrial use can be greatly influenced by the behavior of users compared to general buildings such as residential and commercial, it is necessary to pay attention to various phenomena occurring in the area more locally than the uniform supply policy. Based on these findings, this study contributes to illuminate the legal system related to building act in the Seong-su semi-industrial area and the potential direction of architectural suggestions in related policies and researches.

Although Changgyeong-gung was devastgated by Japanease invasion in 1592, it was restored during the reign of Gwanghaegun, had remembered of early Joseon danasty's architecturural order. It was destroyed several times by fire after that but was rebuilt immedieately. There are Donggol-do and Donggol-dohyeong, so we can fine the change of architectures in Changgyeong-gung. Jibbokheon(集福軒) and Yeongchunheon(迎春軒) are marked in another location and architectures in Donggon-do and Donggon-dohyeong. The reason has been known that it was rebuilt after the fire in 1830. As a result of reviewing the record of birth of crown prince Sado and movement of coffin of King Jeong-jo in funeral ceremony, it was confirmed that notation of Jibbokheon and Yeongchunhyeon was misprinted. In particular, Yeongchunheon confirmed the possibility that the existing building was built by extending it while applying the asymmetrical building with four-purlins structure method during the reign of King Jeongjo, and that it was reconstructed by moving Yeonyeonghap when it was destroyed by fire 1830. And although now Jibbokheon and Yeongchunhyeon(延英閤) are connected, nothern part of Jibbokheon did not burn in the fire, so it was judged that original architectural plan were maintained until now. The current building north of Jibbokheon was built before 1695 (21st year of King Sukjong), which was first identified in the Gunggeolji(宮闕志), and there is a possibility that it may have been a part of Janggyeongmun(長慶門) inner corridor built before 1633. The present building north of Jibbokheon has great architectural significance in that it maintains the structural method of the early Joseon Dynasty which was often applied to buildings with a small scale of inner palace.

Urban campus, one of the main urban facilities, is the representative place that is struggling with 'gridlock'. Due to privatization of space among different departments and space shortages, gridlock has been occurring as a result. The urban campus trying to solve this problem by changing the quality of space, especially the structure of the shared space, which is expected to be the solution to the grid lock problem. The main purpose of this study is to investigate the structural change in the university's shared space based on paradigm transition. The theoretical consideration is to analyze the spatial characteristics of university shared space that appear at different stages through a new perspective that compares the gridlock phenomenon and the shared paradigm. The framework of the analysis of the shared space, which has recently been restructured, is classified into the spatial characteristics of collaborative space, the creative space, and the common/complex space. In addition, these spatial characteristics are again analyzed through the division of legislative facility classification, management governance subject, area, building location and layout, exposure to the outside as well as the analysis of student and staff entry and exit, sharing structure of site and space, and the classification of program characteristics. The results are as follows: The restructured space is systemized so that the management governance of each space would be connected to each other to share information and space. Furthermore, the spatial boundary between colleges or between campus spaces are not only physically, but categorically clear. The restructured space has semi (or in-between)-spatial characteristics such as the intersection in inside and outside of the pedestrian's circulation and the mixture of programs. This study could serve as principal references in presenting the systematic analysis of directions of the shared spatial structure for the urban campus where new educational space is required due to the changes in the university system.

Problems of under-sized dams (small dams with large basin area) could get worse under the global warming condition. This study evaluates the possible change of these problems with the Namgang Dam, an under-sized dam in Korea. For this purpose, first, this study simulates the dam inflow data using a rainfall-runoff model, which are then used as input for the reservoir operation. As a result, daily dam storage, dam release, and dam water supply are derived and compared for both past observed period (1973~2022) and future simulated period (2006~2099) based on the global warming scenarios. Summarizing the results are as follows. First, the inflow rate in the future is expected to be increased significantly. The maximum inflow could be twice of that observed in the past. As a result, it is also expected that the frequency of the water level reaching the high level is increasing. Also, the amount and frequency of dam release are to be increased in the future period. More seriously, this increase is expected to be concentrated on rather extreme cases with large dam release volume. Simply, the condition for flood protection in the downstream of the Namgang Dam is becoming worse and worse. Ironically, the severity of water shortage problem is also expected to become much worse. As the most extreme case, the frequency of no water supply was zero in the observed period, but in the future period, it becomes once every five years. Both the maximum consecutive shortage days and the total shortage volume are expected to become more than twice in the future period. To prevent or mitigate this coming problem of an under-sized dam, the only countermeasure at this moment seems to be its redevelopment. Simply a bigger dam with larger dam reservoir can handle this adverse effect more easily.

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.
