With old housing being renovated in both the Gatdui and Daean areas, of the Gyeongju downtown area, this study was carried out to examine the implications of various renewal approaches in a city that is rich in both history and culture. The study included a physical survey of the areas under construction as well as a questionnaire given to residents to analyse their level of satisfaction with and requirements for housing and their preferring housing types. The study also analysed renewal patterns among the residents were analysed by examining the ways in which particular renovations had been performed. The findings showed that both governmental authorities and private parties need to be involved and work together if such renewals are to be successful. In recent years there have been regular conflicts between those in favor of development and those in favor of preserving the historic and cultural resources of the city. At times the city identity has been neglected by residents. In the future, it will be necessary to take both development conditions and the residents' economic situations into consideration when making decisions about renewal and to consider a wide range of methods for rearranging housing patterns, with the goal of transforming housing renovation into a broader program of social rearrangement for the purpose of improving social patterns in the city.

With both Gatdui and Daean areas, under construction for upgrading the old housing in Gyeongju downtown area, this study was carried out to find out implications of upgrading methods in a historical and cultural city, by using a physical survey in the areas and life survey among their residents, as well as by analysing the level of their satisfaction with and requirement for housing and their preferring housing type. The upgrading patterns of residents were analysed by examining cases constructed newly in the manner of upgrading. The findings showed that it is required for both existing authorities and private parties to assume roles and responsibilities for upgrading the old housing while recently there have been continuous conflicts between development and preservation of the historic and cultural resources within the city and even the city identity also has been neglected by residents. In addition, it is necessary to take development conditions and resident's economic situation into consideration and introduce a wide range of methods for rearrangement, by turning the importance of housing upgrading to social rearrangement for the purpose of positive alternation.

This study aims to analyze characteristics of residents' housing life-style targeting Gatdui area and Daean area where the housing environment improvement project is carried out in the form of rehabilitation housing renewal program of old residence of the downtown area in Kyungju. This is in order to examine realistic problems of the method of residential improvement project, where residents' voluntary participation and preferences are low for low-income residents by seeking the methods of rehabilitation which correspond with the fundamental objective of the housing environment improvement project for low-income residents in urban areas. Based on the survey, we analyzed residents' satisfaction level with the current way of living and preferred ways of living and the planar pattern of houses in surveyed areas, and examined the housing environment improvement methods for residents living in the urban slam areas and perception of subjects. Survey analysis used statistics program SPSS14.0. As a result, of it, it was found that residents in surveyed areas were relatively satisfied with the current way of living but in the preferred housing life-style, they were demanding some change. This paper is significant in that it aims at change in paradigm of improvement of residential areas through renewal of urban deteriorated residence that characteristics of changing living space are compromised depending on living habitude left, and changing life style, and it proposes the directions of the housing environment improvement plan in the future.

In Apr. 2004, the 1st phase of Gyeongbu high speed railroad line was opened between Seoul and Busan, and this new high speed railroad service has increased the customers' satisfaction index and railroad passengers' profit. Moreover, at the end of year 2010 the 2nd phase of Gyeongbu high speed railroad line will be open, and the journey time between Seoul and Busan will be shortened and the new high speed railroad service will be expanded to Gyeongju & Ulsan area. This study will introduce the operation of connection service between new stations and downtown to the 2nd phase Gyeongbu high speed railroad station (Gyeongju, Ulsan station), and analyze the effects of connection service using connection demand analysis and also economic effects. This kind of connection service will contribute to the increase of passengers' satisfaction index and high speed railroad revenue.

This study aims to conduct a depth analysis of motivation and value of local residents and tourists based on means-end chain theory. The sampling of the study was conducted on local residents living near downtown area of Gyeong-ju City, and tourists through soft laddering and hard laddering methods. A mutual correlation model in relation with Hierarchical Value Map (HVM) for each group by conducting the analysis of factor loading (attributes, consequences, value) and cognitive structure (the correlations among attributes, consequences and value) was proposed and the comparisons of HVM for each group was also conducted. The structured questionnaires using Association Pattern Technique (APT) of hard laddering were utilized to analyze the means and end of value chain structures in terms of the attributes, consequences, value of Gyeong-ju Ancient Tombs. The findings propose that local residents are visiting Ancient Tombs Gyeong-ju City Center for 'Rest and take a walk' as the means, which results in 'Relieving stress' and eventually leads to the 'Improvement of historic and cultural cultivation' as the end. On the other hand, tourists also 'Rest and take a walk' as the mean, which also leads to 'Relieving stress'. However, unlike local residents, it eventually leads to 'Self-reflection and healing' as the end. It is expected that the findings of this study not only recommend us to consider preserving and managing cultural heritages and value of ancient tombs in developing "Ancient Tomb Park in Gyoneg-ju City Center" but also provides baseline data for the establishment of reasonable plans of utilizing tombs, historical and cultural heritages.

Recent earthquakes in Gyeongju and Pohang have raised interest in liquefaction in South Korea. Liquefaction, which is a phenomenon that excessive pore pressure is generated and the shear strength of soil is decreased by repeated loads such as earthquakes, causes severe problems such as ground subsidence and overturning of structures. Therefore, it is necessary to identify and prepare for the possibility of liquefaction in advance. In general, the possibility of liquefaction is quantitatively assessed using the Liquefaction Potential Index (LPI), but it takes a lot of time and effort for performing site response analysis which is essential for the liquefaction evaluation. In this study, a simple method to evaluate the liquefaction potential without executing the site response analysis in a downtown area with a lot of borehole data was proposed. In this simple method, the correlation between the average shear wave velocity of the target location ground and the LPI divided by thickness of liquefiable layer was established. And the applicable correlation equation for various rock outcrop accelerations were derived. Using the 104 boreholes information in Seoul, the correlation equation between LPI and the shear wave velocity (ground water level: 0m, 1m, 2m, 3m) is obtained and the possibility of liquefaction occurrence in Seoul and Gyeongju is evaluated. The applicability of the proposed simple method was verified by comparing the LPI values calculated from the correlation equation and the LPI values derived using the existing site response analysis. Finally, the distribution map of LPI calculated from the correlation was drawn using Kriging, a geostatistical technique.
