In this paper, we examine how the market potential affects wages in the regions of Korea. Following Fallah et al.(2011), we construct a panel data set spanning from 2013 to 2020. After removing the characteristics that do not vary by region, changes in average wages were analyzed using a fixed effects model. Controlling for such region-specific characteristics as human capital, industrial structure, and population, the impact of market potential on wages was analyzed by first examining the entire group of cities in Korea, followed by just metropolitan areas and then small cities only. The regional wages are seen to increase across the board when the market potential improves. It was also found that, when the market potential increases, the resulting wage hike of small cities tends to be greater than that of large metropolitan areas.

This study aims to identify the mechanism of the dark side of social capital in traditional markets in rural areas and explain its impact on market members and commercial districts. As a result of qualitative analysis of interview data for merchants and visitors, the dark side of social capital in the traditional market appears in the form of exclusion, organized corruption, and in-group bonds. The dark side of social capital destroys trust and disconnects communication among the merchants and the members of merchant associations, which in turn changes the thoughts and behaviors of members and negatively affects the members and the commercial district. This study interprets the effects on the attitudes and behaviors of members through the framework of the dark side of social capital. It provides a new perspective on the impact of social capital on changes in rural areas, such as urban-to-rural migration and population decline, by attempting to interpret the attitudes and behaviors of members through the dark side of social capital.

Population distribution in urban space varies with transportation flow changing along time of day. Transportation flow is directly affected by the activities of urbanites and the distribution of related facilities, since the flow is the result of moving to the point where the facilities associated with their activities are located. It is thus necessary to analyze the spatio-temporal characteristics of the urban population distribution by integrating the distribution of activity spaces related to the daily life of urbanites and the flow of transportation. The purpose of this study is to analyze the population distribution in urban space with daily and weekly time bases using the building database and T-card database in the city of Seoul, which is rich in information on land use and transportation flow. For a time-based analysis that is difficult to grasp by general statistical techniques, a four-dimensional visualization method combining time and space using a Java program is devised. Dynamic visualization in the four-dimensional space and time allows intuitive analysis and makes it possible to understand more effectively the spatio-temporal characteristics of population distribution. For this purpose, buildings are classified into three activity groups: residential, working, and commercial according to their purpose, and the number of passengers traveling to and from each stop site of bus and subway networks in the T-card database for one week is calculated in one-minute increments, Visualizing these and integrating transportation and land use, we analyze spatio-temporal characteristics of the population distribution in Seoul. As a result, it is found that the population distribution of Seoul displays distinct spatio-temporal characteristics according to land use. In particular, there is a clear difference in the population distribution pattern along the time axis according to the mixed aspects of working, commercial, and residential activities. The results of this study can be very useful for transportation and location planning of city facilities.

Destination choice analysis is an important issue of transportation demand research. The current study analyses the influential factors for university students' trip destination choice. The university students differ from other population groups in many aspects. The study is concerned with shopping, leisure and amusement purposes of trips, other than obligatory trips such as going to school. University students' daily life differs from those of employees and middle and high school students in the sense that a lot of flexible activities are mixed with fixed activities such as work and school attending. A multinomial logit analysis investigates the significance of the impact of a set of variables including residential location, gender and income of the university student. The results show that these variables affect the destination choice of shopping, leisure and amusement. The analysis also provides interesting interpretation of the relationships of the variables with the location choices, which are particularly relevant to the university students.

Provincial boundary regions need differentiated strategies from non-provincial boundary regions because they form multilayered regional networks with boundary cites and provinces. This paper aims to analyze the attributions of provincial boundary regions' regional networks in the dimensions of commuters, companies, and government and to explore their political strategies. At commuters level, Okcheon, a case study area, forms the strongest regional networks with Daejeon and does not have any regional network with Honam region. At companies level, it forms the regional network with Daejeon, Gyeonggi, and Chungbuk, and with Daejeon(Donggu, Daedukgu), and Gyeonggi(Bucheon) at government level. This paper suggests the following conclusive policies. First, provincial boundary regions should be postulated as the new policy targets. Second, Population and Housing Census should be constructed pan-regionally as the base data of regional network studies. Lastly, cooperation system among local government of the provincial boundary regions should be constructed.

This study aimed to examine the characteristics and types of reformation of local administrative districts in a metropolitan area, focused on the experiences of Japan, where municipal mergers were carried out extensively over the last ten years. Local administrative districts substantially have spatial characteristics. Therefore, the reformation of local administrative districts should be followed by a detailed analysis of the characteristics of the local area. Unlike other regions, the metropolitan area of Japan shows discriminative characteristics of finance, population and centrality. In addition, there are many types of regional context within a metropolitan area. These could be categorized by finance, population, centrality and basic industry. In conclusion, I revealed that municipal mergers could be categorized by their background and process and many issues were contained in each category. It had a meaning that municipal mergers had characteristics that expanded the regional inequality. Therefore, different approaches considering regional characteristics would be required for a municipal merger to be a useful way for regional development.

Integration of GIS data and human expert knowledge into digital image processing has long been acknowledged as a necessity to improve remote sensing image analysis. We propose inductive machine learning algorithm for GIS data integration and rule-based classification method for land cover classification. Proposed method is tested with a land cover classification of a Landsat ETM+ multispectral image and GIS data layers including elevation, aspect, slope, distance to water bodies, distance to road network, and population density. Decision trees and production rules for land cover classification are generated by C5.0 inductive machine learning algorithm with 350 stratified random point samples. Production rules are used for land cover classification integrated with unsupervised ISODATA classification. Result shows that GIS data layers such as elevation, distance to water bodies and population density can be effectively integrated for rule-based image classification. Intuitive production rules generated by inductive machine learning are easy to understand. Proposed method demonstrates how various GIS data layers can be integrated with remotely sensed imagery in a framework of knowledge base construction to improve land cover classification.

After the unification of Three Kingdoms, Silla Dynasty had been on the prosperity with continuous population growth during approximately 120 years. However, Unified Silla Dynasty experienced 11 times of famine and bad year by frequent droughts during 50 years since the late 8th century, and these caused to political, economic and social changes. It is evident that Silla Dynasty slowly declined by the droughts and famines, although ancient records described as still on glory days. Since then, national power of Unified Silla Dynasty was abruptly weakened by migration of residents, and 9 times of rebellion or revolt occurred during 50 years in the late 9th century. As a result, political and social agitations reached the maximum. These led to the collapse of the Unified Silla Dynasty, and King Gyeongsoon handed over the dynasty to King Wanggeon, a founder of Goryeo Dynasty. These resulted from the 500-year-cycle droughts and human activities that seriously devastated the vegetations by using trees as an energy source for hundreds of thousands people during several centuries. The devastation of vegetation destroyed farm lands and led to large changes in river and groundwater systems, and eventually, increased damages by droughts.

Establishments of wholesale of recycling materials are located in the region where an amount of recyclable wastes generated as artery industry developed and the region of rather many population. And they are located not in underpopulated area as noxious facilities, but located in the non-residential area of many population regions in the whole country. Also, establishments of recycling of metal wastes and scrap, and non-metal wastes and scrap are mainly located in the peripheral region of metropolitan cities, regional centered cities, and adjacent regions of industrial area, because of high coefficient of localization, and agglomerated effects of production. The factor influencing the location of recycling industries is deeply connected with the location of wholesale of recycling materials, and thus, the transportation costs to carry recycling materials from supplied regions to plants are important but population is not so important.
