Since the 1990’s cellular automata urban models have been effective tools to study spontaneous land use change and urban growth and to understand various alternative spatial futures. This research uses the cellular automata urban model Metoronamica to simulate urban growth of Seoul Metropolitan Area up until 2030. In order to consider diverse determinants of urban growth and to see alternative futures, it designs three scenarios such as business as usual, deregulation of greenbelts, and introduction of new high speed rail system GTX and then conducts simulation for each scenario. This study showed a way of understanding urban growth process and of planning support with a dynamic urban growth simulation model. Spontaneous growth without any further investment or regulation is likely to result in continuing leapfrog development. Deregulation of greenbelt could absorb spontaneous growth in further part of the SMA but it would harm previously protected areas near Seoul city. Introduction of GTX would promote polycentric urban structure and mitigates dispersed development pattern. Although the study considered a limited number of scenarios and factors, it brought meaningful implications for the future growth of the SMA.

In this study, the locational features of Namhansanseong(南漢山城) and its temporary palace(行宮) will be clarified with the view of Feng shui. Namhansanseong was a fortress which had rough topographic condition. And the temporary palace that was located in the fortress was the place for King InJo to command the army at the Manchu war of 1636. The location of Namhansanseong and its temporary palace was selected by Feng shui. Especially, several features of Feng shui were applied to the location of temporary palace. However it did not appear the best condition of Feng shui. Because of the limitation that the palace should have located in inner fortress, there was no room to consider sufficient plots. The place on which the palace was built was the best condition among the inner fortress plots. For this reason, the temporary palace was constructed as an royal office rather than a palace that was its own purpose.

A co-working partnership approach among various stakeholders and organizations in neighbourhood regeneration has been emphasized to respond effectively to social, economic, and physical problems in declining neighbourhoods. This study aims to find implications for urban regeneration partnerships building a collaborative governance in neighbourhood regeneration. This study explores the process of establishing a partnership to deliver the ‘Angel Village Festival’ which is one of urban regeneration programmes for the Jeonju test-bed. The festival was suggested from a cultural asset called ‘a faceless angel’. Through the process of preparing and implementing the festival, a coworking network with a range of partners has been organized and developed. The partnership was originally designed to be representative of local communities and developed to involve partners from the public sector, the private sector, and the civic sector. The partnership centered at the governance structure for the on-going development of the festival. Based on this case study, the partnership approach in neighbourhood regeneration is expected to facilitate effective responses to challenges, trust building, and capacity building for local communities.

We examine the relationship between consumer sentiment and residential housing price. Using Vector Autoregressive (VAR) model, we derive a determinant model on sentiment index with macro economics variables. Results indicate that the sentiment index is affected by price of Cheonsei, consumer price index, housing construction and exchange rate. After decomposing sentiment index into rational (explained by macro economic variables) and irrational (unexplained residual) component, we find that both rational and irrational component has influenced housing price index. We adopt the BDS test to reduce a possible bias from omitted variables in which we strengthen the robustness on decomposing rational and irrational component. Additionally, impulse response test suggests that change in rational and irrational sentiment has asymmetric effect on residential housing market.

This paper analyzes yearly variation of the air passenger travel volume for domestic routes connecting major airports in Korea. Using aggregated statistical data, yearly variation of the air passenger travel volume is analyzed. The paper includes some descriptive statistical analyses on time-series data for domestic routes connecting major airports. The analysis is conducted on the period between the year 2002 and 2011. Furthermore, some direct air travel demand models are developed by panel regression analysis for finding factors affecting air passenger travel volume of each domestic route connecting major airports. Finally, some analytical results are summarized, and policy implications are discussed. The analytical results are summarized as follows. First, it is found that the air passenger travel volume for domestic routes connecting major airports, excluding Jeju and Incheon International Airport, is decreased between the year 2002 and 2011. Secondly, it is found that populations of origin and destination are the most important factors affecting air passenger travel volume.

The study of development control of foreign countries says that planning system, regulation system, review and permission process are useful for performing land use control effectively. The U.S. development control system has detail specific regulations for each land use, while Germany has B-plan (detailed district plan) and British has various review and permission processes in their development controls. On the one hand, Korea has actually the system mixing the three, it seems to have a zonning system though. The characteristic of Korean development control system gives confusion to officials and causes disorder in its development control. However, Korean development control system will expect to go to the planning system or the review and permission process, due to changing the circumstances in planning and improving the requirements of deregulation of land use system. Thus, it is very important to readjust the planning system and to improve the review and permission process in Korea. The opinions of experts about the time to transform into that kind of controlling development system are different. However, the time may be expected when the development demand decreases and the increase rate of population declines.

Water shortage estimation by drought frequencies is an important factor for establishment of efficient water resources development and management planning. However, the research on the method to estimate water shortage by drought frequencies based on water supply and demand is not enough and it is necessary to establish a methodical approach. In this research, the way to estimate the water shortage based on drought frequency in the process of national water plan is studied. Firstly, the effect of water supply capacity of agricultural reservoir on water shortage is analyzed in the frequency of droughts over 20 years. In addition, the way to calculate water shortage based on drought frequency for each sub-watershed is examined. As a result, water shortage has increased if water supply capacity of agricultural reservoir is not considered and this can be mostly observed in Geum River basin. Also, it is confirmed that improvements of the existing method for estimating the water shortage of national water plan is required. The results of this study can be used as useful information for water resources planning and management of the central and local governments in the future.
