This study aims to investigate the changes in the occupational structure of employment in Korea during the last three decades, in which have transformed from industrialized economy to knowledge-based economy very rapidly as well as having experiences of both IMF and financial crisis. For this purpose, we analyze the trends occupational distribution and the socio-demographic characteristics of the occupational structure of employment since 1980. By applying correspondence analysis of Multidimensional Scaling(MDS) methods, we examine the inter-relationships between the employed persons by occupation and their characteristics such as gender, age group, educational attainment, industry, region. We found the occupational structure of Korea has been changed dramatically with the socio-economic transformations during the last four decades. In particular, the occupational (job) structure has been highered in general. However, it has also been dualized extremely into two groups, one is the specialized-skilled-white color jobs and the other is the simple-unskilled-blue color jobs. The results of this study could be utilized as the importation basis for the provision of labour supply and employment policy plan at the national level as well as at the local level.

This study investigates the time-space characteristics of the road traffic flows in Seoul and the relationship with land use patterns. For the purpose, we analyze the road traffic data collected at 118 observation sites over Seoul City area since 1993. We examine the time-trend of the annual average traffic flows per day during the last fourteen years. Three different trends are revealed: rapid increase during the time period between 1993 and 1997, maintenance same level after sharp decrease between year 1997 and 1998, and gradual decrease after sharp decrease between year 2003 and 2004. The spatial distribution patterns of road traffic flows have also been changed significantly during the period. The traffic flows in the urban center have been declined gradually, while the traffic flows in the boundary area and southern CBDs have increased dramatically. In order to examine the relationship with the changes in the land-use patterns and road traffic flows, we analyze the changes in the spatial distribution patterns of population and industries. We developed three multiple linear regression models to test the relationships between the changes in the land-use variables and road traffic flows.

The purpose of this research seeks to analyze the spatial variations in the sex age structure which have been shown to exist within the study atrea, the Kyonggi province in Korea. In this study it is desired to use the Age Structure Index developed by Coulson in order to describe thi sex age structure of each of 186 tracts that comprise the tracted portion of the Kyonggi province. The mechanics of computing the Age Structure Index are found in the equation describing a linear least squares trend line: y=a+bx. For each census tract, the percentage of the population in each age group(y) was plotted against the middle age of each age group(x). The a is a constant representing the value of y, when x equals zero. The b is the regression coefficient and is a measure of the angle of the slope of the least squares trend line. Thus the value of b is the Age Structure Index for each census tract. The major results of this investigation can be summarized as follows: The spatial distributions of sex age structures in the Kyonggi province are far from random. They have exhibited great regularity with the yonger sex age structures near Seoul and a sharp decline to the older sex age structures out in all derections towards rural region. The results of this investigation should have important general significance for the study of the Kyonggi province Age Structure Index is a flexible, operational definition shich allows sex age structure to be measured, mapped, and incorporated in a wide variety of methods of statistical analysis. Futurer, it has been demonstrated that sex age structure varies spatially within Seoul metropolitan finge and that this variation is relagfed to many other attributes of the population. Especially, Age Structure Index is strongly related to the variables-rate of population growth rate. density, rate of numbers of manufacturing, land price. At the same time, considerably more research is needed before a genmeral body of knowlege concerning sex age structure can be developed.

The ultimate goal of urban regeneration is the economic development and activation of region. In order to continue to management the urban regeneration projects and to achieve a goal, we should look at the recognition of people visiting the place. This recognition is represented as a place attachment. Place attachment is the realizing means for local activation by inducing a lot of attention and a visit to place. Accordingly, this study was selected the Jungang-dong in Cheongju as a case study and measured awareness of the physical environment and activity programs. Based on the survey, this study analyzed the impacts of awareness of urban regeneration project on place attachment by carrying out multiple regression analysis. According to the analytical results, Visitors formed an place attachment called 'I want to stay here longer' and 'I will miss here if this place has changed'. However, visitors are unable to form an place attachment called 'Here is a distinctive place'. Finally, this study suggests the direction of urban regeneration projects to reflect the physical environment and activities programs at the same time and form the rich psychology of visitors.

Land suitability assessment(LSA) is a useful method to assess land characteristics according to its physical, locational, and environmental characteristics, and then to classify it into several categories based on its usability and the necessity for conservation. Therefore, the credibility of this assessment result depends on the rationality of assessment method such as computation of suitability values and the criteria of ranking the land grade. This study focused on identifying problems in current LSA method by critically reviewing it, and aimed to suggest a suitable method for the assessment of land suitability. As a alternative method in this study, linear transformation method was used for scoring factors instead of critical values and the weight for each assessment factor. and all values of those factors were added to produce comprehensive suitability values. Those values were ordered and categorizied with suitability level based on the ratio of square measure. After comparing existing LSA method to the suggested alternative method, it is concluded that the alternative method was more suitable to assess the characteristics of lands than existing LSA method. This method was also suitable to represent the characteristics of various assessment factors. Field survey using satellite image clearly revealed the suitability of the alternative method compared to an existing method of land assessment. Furthermore, the alternative method of grading the land suitability improves the problem of using standardiZiation method and gives more flexibility, which makes this method very rational.

This study looks into existing discussion about the entry time and the geographical criteria point of 'Ho-Nam' as a place name. And discusses the reason which the geographical criteria point is not clear with emphasis on the possibility of the geographical range change of place name. The result is as follows. Firstly, the regional criteria of 'Ho-Nam' is Kum-River if we consider direction and the role as a regional barrier among the existing offered criteria. Secondary, the criteria of Ho-Nam and Ho-Seo might be different each other. A place name of Ho-Nam had appeared before Chosun period as a geographical concept and changed to the cultural concept during Chosun period. And Ho-Seo was established in Chosun period. But 'Ho-Nam=Jeon-la Province' and 'Ho-Seo=Chung-cheong Province' is established during Chosun period as a cultural concept. Thirdly, the geographical range of Ho-Nam of Go-Ryeo period and Chosun period were different each other. Fourthly, the criteria of Ho-Nam may be the Han-River if we consider the entry time and geographical range change.

In this study, the spatio-temporal characteristics of summer extreme precipitation events in the Republic of Korea are examined based on the daily precipitation data observed at approximately 360 sites of both Automatic Weather Station (AWS) and Automated Synoptic Observation System (ASOS) networks by the Korea Meteorological Administration for the recent decade(2002~2011). During the summer Changma period(late June~mid July), both the frequency of extreme precipitation events exceeding 80mm of daily precipitation and their decadal maximum values are greatest at most of weather stations. In contrast, during the Changma pause period (late July~early August), these patterns are observed only in the northern regions of Geyeonggi province and western Kangwon province as such patterns are detected around Mt. Sobaek and Mt. Halla as well as in the southern regions of Geyeonggi province and western Kangwon province during the late Changma period (mid August~early September) due to north-south oscillation of the Changma front. Investigation of their regional patterns confirms that not only migration of the Changma front but also topological components in response to the advection of moistures such as elevation and aspect of major mountain ridges are detrimental to spatio-temporal patterns of extreme precipitation events. These results indicate that each local administration needs differentiated strategies to mitigate the potential damages by extreme precipitation events due to the spatiotemporal heterogeneity of their frequency and intensity during each Changma period.

In this study, long-term changes in means and extreme events of precipitation during summer rainy period called Changma (late June~early September) are examined based on rainfall data observed by Chukwooki during Joseon Dynasty (1777~1907) and by modern rain-gauge onward (1908~2015) in Seoul, Korea. Also, characterizations of the relevant changes in synoptic climate fields in East Asia are made by the examination of the NCEP-NCAR reanalysis I data. Analyses of 239-year time series of precipitation data demonstrate that the total precipitation as well as their inter-annual variability during the entire Changma period (late June~early September) has increased in the late 20th century and onward. Notably, since the early 1990s the means and extreme events during the summer Changma period (late June~mid-July) and Changma break period (late July~early August) has significantly increased, resulting in less clear demarcations of sub-Changma periods. In this regard, comparisons of synoptic climate fields before and after the early 1990s reveal that in recent decades the subtropical high pressure has expanded in the warmer Pacific as the advection of high-latitude air masses toward East Asia was enhanced due to more active northerly wind vector around the high pressure departure core over Mongolia. Consequently, it is suggested that the enhancement of rising motions due to more active confluence of the two different air masses along the northwestern borders of the Pacific might lead to the increases of the means and extreme events of Changma precipitation in Seoul in recent decades.

This paper analyzes the pubic nature of New Genre Public Arts. It is very sensitive to the social issues and supports democracy and communities with the diverse civic participation. Therefore, it is be widely known without doubt that new genre public arts is more public in nature compared to the previous public arts. This research observes the practices of new genre public art and focuses on the problems of the revealing nature of new genre public art through the analysis of the interrelations among government, artists, and the residents by through observation on the , Seoul City Gallery project from October 2008 to January 2009. The implementation of the project is divided into three constituent parts: local government for funding, artists for planning and implementing, and residents. Local government supports and commands the public art works to create more competitive and harmonious city. Artists emphasize the revitalization of community and take the residents as the passive objects of enlightenment. Whereas, the residents hope to use the funds to improve economic conditions. Artists accept the top-down commands of government, whereas residents tend to passively participate and become objects for enlightenment by artists, after all, might be alienated by the project. These kinds of communications and relationships raise the issue of the possibility of failure of public arts projects.

Resident's attitude and evaluation about local or urban development policies is a major factor in the process of the regional and urban 1)tanning and its practices. Therefore there are numerous studies pointing to analysis about the evaluation of the urban development policies. The purpose of this paper is concerned on the residents'cognitions, attitudes and evaluation about of urban development policy of Sunchon City in South Korea. Research area, Suncgon city, has been served as a central place of eastern Chollanamdo since 1920 and now functions as economic and commercial leading city of Kwangyang-bay area. In addition, Sunchon city is fastly growned with the influence of national development policy including the establishment of major industrial estates and the construction of container port in Kwangyang-bay area. In the overall cognition and evaluation about the quality of life of Sunchon city, most people are satisfied with the quality of life of urban living comparing with near cities such as Kwangyang and Yosu city. In particular, the level of satisfaction about education, transportation, natural environment are relatively higher than economic condition and living facilities. Most of residents have positive attitude and evaluation about the image of future urban development, and prefer to culture and education city in urban function of Sunchon city. Therefore, in order to function as a central city of Kwangyang-bay area. Sunchon city have to adopt new urban development policy including such as reconstruction of urban spatial structure, strengthening of culture and education functions, and the related facilities, restructuring of regional industrial structure. and expansion of commercial and shopping facilities.
