The urban form of Korean cities significantly changed in the late Chosun dynasty. The influence of commercial development was the main cause of these changes. Commerce became a important function of existing cities, and the new type of commercial towns emerged at the important spots of traffic routes. In both cases streets became dominant element of urban form. Mainly commercial buildings aggregated along the streets, and to obtain higher land use intensity shape of lots became narrow and deep. Koyang(高陽) shows the most significant example of this new type of lot and lot pattern. Approximately 30 narrow and deep type of lots lined on each side of street forming about 390 meters long linear commercial town. Similar examples were found at the outside of south gate of Suwon(水原), Nuwon(樓院), and Pangyo(板橋).

From the early 1980's, when Chinese government decided to take an Open-Policy. Chinese society faced a new turning point to be changed from traditional-society to modern-society. As a result her outstanding phenomena of civilization is to be seen in many points, like the oid styled traditional street is rapidly replaced by the modernized high-rise buildings. Like the other cities in China, Beijing(北京) also is on the step of modernization, and it's changing speed is faster time by time. In this paper, I'll discuss about Beijing's policy of reservation of Old castles(古城), some problems what they have though the procedure of China's Movement of Old Castle Reservation(古城保護運動). And through this case study, I'd like to focus on the way how we solve some problems what we have now concerning to the reservation and development of traditional cities.

This study evaluates collapse probabilities of structures which are designed according to a domestic seismic design code, KBC2009. In evaluating their collapse probabilities, to do this, probabilistic distribution models for seismic hazard and structural capacity are required. In this paper, eight major cities in Korea are selected and the demand probabilistic distribution of each city is obtained from the uniform seismic hazard. The probabilistic distribution for the structural capacity is assumed to follow a underlying design philosophy implicitly defined in ASCE 7-10. With the assumptions, the structural collapse probability in 50 years is evaluated based on the concept of a risk integral. This paper then defines an mean value of the collapse probabilities in 50 years of the selected major cities as the target risk. Risk-targeted spectral accelerations are finally suggested by modifying a current mapped spectral acceleration to meet the target risk.

According to the complexity and the pluralism of the modern cities, they are changing themselves into the multinoded and social - classless urban environments. The sudden drift of population to the cities is giving rise to the serious environmental problems, and the rapid increase of recreational needs among the citizen is changing the urban society into a leisure - oriented one. In order to coping with the abrupt change in the social and natural urban environments, the various fields of urban society should be co - ordinated. The study uses the green - city concept to get solves the incongruity of urban structure in Chonju City. The existing open space maps were drawn up by the various techniques such as the analysis of the topographic maps and collected data, the interpretation of the aero-photographs and the reconnaissance of site. The authors suggested the existing condition, and the problems and potentials of open space elements in Chonju City through the analysis of the existing condition maps. After synthesizing the contents of analysis, the 7u(hors established an exclusive open space system for Chonju City.

As modern cities have become more developed by making factories and modern industries, the countryside areas were confront with civilization compare than before. Actually, heavy traffic, air pollution, and increasing land price in the cities caused by such a big problem. And people who want to live in countryside try to find house in the context, but it is not easy to satisfy their desire for living. This article deals a way of living, by utilizing Club House, and using natural area more to have a good life during the retirement time, and spending wonderful time at the weekends. Our recommend is providing a countryside village and Second House around the Golf Club for the people who want to spend their leisure time comfortably and taking rest.

The purpose of this study is to develop an underground Building. Population tends to concentrate in large cities. In result, the cities lacks housings. Underground space may be a attractive space by being able to gain alternative energy and get a cheap site, protect environment at the same time. The earth or ground is a useful medium for a long-term heat source and storage of it's heat. Also the underground space has the status of stabilization, the lower heating load and the similar heat transfer coefficient of the inside wall surface comparing to that of residential space. Utilization of underground space has many advantages to cope with lack of building sites and energy conservation, etc. As a result, it is expected to provide a useful information for the practical use of Underground building.

Recently, the structural design code has been changed and every buildings, which have more than three floors or wider area than 1,000m2, should be designed to be able to resist earthquakes. However, most structural engineers are working in some big cities and this physical distance would set a barrier between structural engineers and architects. As a result, most row-rise buildings in small cities are designed and constructed without structural design or the consulting by structural engineers. The purpose of this research is to develop an web-based structural design environment in which structural design and consulting can be performed efficiently through on-line communication without off-line meetings or documents. In addition to the on-line communication, the system has a integrated structural design module which supports all the process of structural design and can increases the productivity of structural design work.

After the historic opening of the first section of KTX(Korea Train eXpress), it has been made changes three times in a plan to pass through cities of Daejeon, Daegu in the construction of the high speed train's second section(underground${\to}$ on ground${\to}$ under ground${\to}$ on ground). Thereafter, it has been repeatedly argued that the plan to pass through underground caused many problems such as prevention of an accident in tunnel, the difficulty of maintainence, the disadvantage of passengers' moving line. Thus construction on ground plan is coming up again with relation to the interest among local people. There have been lots of national budget loss, construction period delay in this project and people hardly trust policies about national project and nor do engineers. It will be presented that the railway line which is accorded with the characteristics of region, an agreement with local communities about national project, the reasonable procedure to determine how to pass through cities, resolve the conflict among neighborhood, and the role of engineers.

According to 'Metropolitan Traffic Network Plan' announced in 2001, radial railways which connect Seoul with satellite cities around Seoul appear gradually. And followed by this, social demand for circular metropolitan railways that can connect the radial railways horizontally is increasing. But existing plans about circular metropolitan railways has limits to propose only passing cities of the railways. If there is no detailed guideline for circular metropolitan railways, the each railway for circular line will be constructed individually and then it will be not effective circular railways totally. Additionally that railway project will be easily interrupted by popular complaints. Therefore "The basic plan for circular metropolitan railways" is needful to guide a right direction for circular metropolitan railways. In this paper, rough track diagram of 'node' station for circular metropolitan railways is proposed. It is essential part of the basic plan. If the track diagram of a node is publicized in advance and individually lines of circular metropolitan railways is enforced to followed it, all lines will has rich circular functionality. Finally, effective circular metropolitan railways can be built.

The fire department has one of the most important role as public resources of response to disasters in the aspect of supply and the adequate distribution of resources of response is essential, but the distribution of the response capability to disaster of fire department does not reflect the regional hazard vulnerability and hazard risks. Researchers performed database process with simple mapping based on the regional fire disaster response capability and the regional hazard vulnerability and hazard risks. The cities and towns are divided to four types each, total eight types and relative threat ratios are extracted from every type. The fire disaster response capability was extracted from number of firemen and fire vehicles in defined region. The distribution of the fire disaster response capability was inadequate and not matching to relative threat especially in small cities and some types of towns. The regional relative threat and resources should be analyzed by more delicate mapping and software development in the future.
