A plaza represents the identity of a city, and that reveals a plaza's importance. Gwanghwamun Plaza and Seoul Plaza are two representative plazas where the citizens can freely express their opinions. Many major plazas in the center of Seoul were built under the Japanese occupation. Among these, the plaza of Joseon Bank has different characteristics than Gwanghwamun Plaza and Seoul Plaza. Even though this plaza was built in the center of the commercial, administrational, and cultural district during the Japanese colonial period, the research on this plaza has been limited. This study was conducted to verify the features of this plaza by analyzing its construction and transformation during the Japanese colonial period. The study's results outline how the plaza was constructed by the Japanese administration. The intention of the government is shown by the fact that it purchased land parcels and held a design competition. In the 1910s, the government purchased seven parcels of land during the expansion of roads as the place for the plaza. During the late 1930s, the government accepted a traffic circle to regulate the traffic and eliminate the conflict between crossing movements. In 1939, a fountain was built in the plaza's center, and its design was selected through a design competition. It was planned as a square, but gradually turned into a rotary. Furthermore, the plaza was a landmark and symbol of the power and modernity of Japan. As the main modal point of public transportation, the plaza became surrounded with largescale Western-style buildings, commercial advertising, and neon signs. The plaza became a place where people could experience the modern city. These spectacular displays showed that Japanese imperialism was perceived as a strange and peculiar landscape to the majority of Korean citizens. This study investigates the history and characteristics of the plaza, focusing on its beginning as well as the transformation of its form. As to the limitations of the study, it does not consider political and economic contexts within the transformation of Seoul and in relation to this plaza. Instead, that research remains for a future study.

Recently the function of a department store has changed to the concept of a multi-functional center because of the alternative stores such as discount stores, home shopping, and internet shopping. This means that the front plaza of a department store is not a personal or private space any more, but a public space. This study focuses on the special character of public space through the classification and preference types of department store front plazas. The major results of this study can be summarized as follows: (1) Components of front plaza of department store are classified by three factors. The first factor, named "space limit", has 14 elements ; the second, named "space decoration" has 16 elements ; third, named "activity", has 2 elements. The first preferred element is easily- used and easily- serviced wide space. The second preferred element is the equipment that is placed linearly along the street. The third preferred element is cultural events. (2) The comparison between the frequency and preference shows that the plazas could not satisfy the user-needs. (3) Preference factors of front plazas were examined to three characters such as familiarity, peculiarity, and openness. Familiarity, peculiarity, openness have a positive correlation in all types. Peculiarity especially influences the other two space - preference factors.

This study examines the spatial structure of Jeju-eupseong (Town-castle) in the Joseon Dynasty. The spatial structure of Jeju-eupseong has distinctive features and regional characteristics that are substantially different from typical eupseong in inland regions. This is mainly attributed to the geographical characteristics of the island and the administrative system with strengthened military functions. Jeju-eupseong displays a distinctive layout of major buildings and road system with a plaza located in its center in comparison with the ones found in inland regions. Gwandeokjeong Plaza in Jeju-eupseong served as the center of Jeju's politics, administration, and culture during the Joseon Dynasty, and it, in the modernization period, has become an open public space in the heart of Old Downtown used for community gatherings. Therefore, this study aims to explore the historical background and distinctive spatial structure of Jeju-eupseong in comparison with eupseong in other parts of Korea. Moreover, the study examines the characteristics of Gwandeokjeong as a plaza that has not been dealt with in other studies of eupseong.

Public spaces in the cities are social and economic resources to maintain sustainable urban revitalization. As an importance of public spaces is getting increased, many cities focus on public space management and introduce their own management system. NYC Plaza Program is one of the public space management systems in USA and it was designed in order to transform underused roads and streets into pedestrian public spaces throughout the New York City. Plaza management system works with private organizations' participation as NYC Department of Transportation empowers selected private organizations to the right of management and assists their efforts. In this study, we focused on how the plazas are managed by private sectors and seek to find out characteristics of types of management methods based on landuse(residential, commercial and openspace) status around plazas. We analyzed 61 plazas that generated by NYC Plaza Program with three major conditions of management system including organization, fund and activities. There are three major findings from the analysis. 1)In most residential surrounded plazas, resident-initiative organizations manage small scaled fund and activities meanwhile public agencies support their management. 2)BID is a dominant tool in the commercial surrounded plazas. BID provides with secured fund, mid-sized activities and a broad network with commercial facilities. 3)Openspace-surrounded types are usually using supports of exiting organizations and fund system.

We review here research and development progress achieved in US Plasma Chamber technology roughly over the last decade. In particular, we focus on two major programs carried out in the US: the APEX project (1998-2003) and the US ITER TBM activities (2003-present). The APEX project grew out of the US fusion program emphasis in the late 1990s on more fundamental science and innovation. APEX was commissioned to investigate novel technology concepts for achieving high power density and high temperature reactor coolants. In particular, the idea of liquid walls and the related research is described here, with some detailed examples of liquid metal and molten salt magnetohydrodynamic and free surface effects on flow control and heat transfer. The ongoing US ITER Test Blanket Module (TBM) program is also described, where the current first wall/blanket concepts being considered are the dual coolant lead lithium concept and the solid breeder helium cooled concepts, both using ferritic steel structures. The research described for these concepts includes both thermofluid MHD issues for the liquid metal coolant in the DCLL, and thermomechanical issues for ceramic breeder packed pebble beds in the solid breeder concept. Finally, future directions for ongoing research in these areas are described.

The fast and competitive urbanization has accelerated unbalanced land utilization and housing, thereby producing large number of decaying areas and socially disadvantaged population, while generally promoted citizen's quality of life. Since rental housing policy, therefore, has emerged as a major important issue to solve these ever increasing problems, new concepts in leading examples need to be explored to stimulate creative ideas for future housing improvement. The purpose of this research is to extract successful factors of a leading rental housing 'Manhattan Plaza' in New York city, expecting useful implications for housing improvement in Korea. Field visit and in-depth interview for data collection and qualitative approach for analysis were carried out. As results, its successful sustainability and fame were found to be attributable to following concepts, such as, socially integrative mix of diverse residents, residents' participation in management, privacy respect administration, considerate planning and design features of physical environment. The latter, especially, were prominent in peripheral spaces, indoor and outdoor community spaces, and private spaces. Based on the results, suggestions were made for future Korean rental housing development.

This landscape design proposal was presented to a design competition for the New Government Buildings of Dalseong-gun which was held by the municipal authority of Dalseong-gun in June, 2002. The site is located at 1313 Gumpo-ri, Nongong-eup, Dalseong-gun, Daegu Metropolitan City and has an area of 50,000$m^2$. The judging criteria for the landscape design set by the Dalseong-gun could be articulated as follows : an environmentally friendly design which respects the surrounding n a locale which functions as a community center of Dalseong-gun, a resting place for the welfare of its employees and visitors, and finally a place with diverse landscape elements reflecting the individual identity of each facility. The main design concepts of this project could be summarized as follows : an environmentally friendly design which respects and utilizes the existing natural landscape resources, a design which features a harmony of nature with architecture and exterior space with interior space, and a design which balances esthetic form and practical function. This design consists of four major outdoor spaces ; the lawn, the entry plaza, a pine grove, and a deck area on the third floor. The multi-purpose lawn area near the main entrance area can be used for flea markets, outdoor weddings, and picnics for its neighbors. The adjacent plaza and parking lots can be unified as one space in case of large events. The entry plaza has three axes. Each of them represents the Assembly, the Administration, and the Culture. A big circle in the paving pattern unifies the three individual axes. A group of Zelkova trees was introduced to reflect local flavor. The existing pine grove was preserved as a symbolic 'park' for the Gumpo district. The outdoor amphitheatre within the grove was introduced by utilizing the existing topography, The flow of 'nature'on the deck area was designed to connect Mt. Gumkae with the 'city'. It is a comfortable resting place for its employees and visitors.
