Land privatization in Mongolia has resulted many urban problems such as relatively high land price and high concentration of population in Ulaanbaatar city. The purpose of this study is to analyze the changes of the land privatization policy in Mongolia from 2003 to 2013 and their influences on Ulaanbaatar by analyzing online news articles. The followings are the results of this study. First, the low rate of land privatization by lack of understanding at every phase has led to the extension of period of privatization and the revision of land law. Second, land privatization has resulted in land conflicts and urban environmental issues in Ulaanbaatar city. The latter was caused by urban sprawl which stemmed from the accelerated population concentration. Furthermore, the population concentration in Ulaanbaatar has extended the Ger area, which has led to the shortage of land for privatization and land and air pollution since the area has no urban infrastructure for living. Also it brought up the necessity of urban planning for administration planning. Lastly, the urban problems in Ulaanbaatar have been accelerated by irregular operation of land privatization due to bribe and overlapped privatization.

This study examines the relationship between land use mix and pedestrian volume using the 2009 Pedestrian Activity Survey in Seoul, Korea. Focusing on the various types of land use mix, this study identifies the most influential combinations of land use mix that have significant associations with higher pedestrian volume. The results are as follows. First, pedestrian volume is more likely to be higher in the commercial areas including sales facilities or traditional market facilities rather than residential areas. Second, if all things are equal, the total floor areas of neighborhood-level commercial facilities are positively associated with pedestrian volume. The total floor areas of office facilities also show a positive association with pedestrian volume. Third, this study identifies the combination of residential use with neighborhood-level commercial facilities, retail facilities, offices, and other facilities as the strongest land use mix that is associated with higher pedestrian volume. However, retail facilities such as big-box stores and department stores do not show a positive association with pedestrian volume. We assume that these facilities are more likely to be associated with cars rather than walking. This study contributes to public policies that tend to promote walking activities with mixed land use strategies in the mega-cities. Future studies need to address the best combinations of land use mix for walking activities in the context of local land use conditions.

Zoning system intends to derive the land use in the desired direction through various regulatory actions, or restrict certain land use. In order to reap the effective behavior control as a means to achieve the objectives of zoning, land users should be able to easily understand the details of behavior control. This study attempt to organize the details of behavior control clearly from the perspective of the users or consumers. Major findings of the study are presented as follows. First, The elements of the behavior control are largely classified as the expression of subject to regulations, the regulations of appearance and the administrative regulations. Second, The types for separated three regulatory element are analyzed. Finally, based on the derived typology, the framework for behavior controls of each zoning is established to understand the details of behavior control easily. This framework has the advantage that allows you to understand the contents of the regulations by clearly indicating the elements of the behavior control.

The purpose of this study to examine the relationship between leisure trip on weekday and the personal characteristics and neighborhood built environment in Seoul. We analyzed the characteristics of the weekday leisure trip, and identified the difference of characteristics with the trip origin being classified into home and office. This study used [2010 household travel diary survey in the Seoul metropolitan Area]. The results of this study are summarized as follows. First, The average travel time for leisure trip was around 30 minutes, and leisure trip distance was average 3.5㎞. Second, the leisure trip distance from a office was longer than that from home. But, travel time for leisure trip from a office was shorter than that from home. While the rate of using a car and railroad from a office was higher, the rate of walking and using a bus from home was higher. Third, factors influencing weekday leisure trip included availability of a car, type of house, income, land use mix, type of trip origin, travel mode choice, and accessibility. Fourth, there was a difference between factors influencing leisure travel from a office and home. There were more factors influencing the travel departing from residence than those from a office. This study suggests that, weekday leisure travel in Seoul, there was a significant relationship between the leisure travel time and distance according to urban physical environments.

As a response to the problems of urban sprawl, scholars have suggested New Urbanism and Smart Growth strategies. Among the various components of the land use strategies, mixed land use development has gained increasing attention. However, the effect of mixed-land use has been relatively less investigated. Particularly, little is known about whether housing demanders really want to live in a neighborhood with mixed-land use. In order to identify preferences of the housing demanders on mixed-land use, we attempt to explore the relationship between mixed-land use and housing prices. To do so, we employ the two-stage least square (2SLS) estimator with instrumental variables to account for the endogeneity between mixed-land use and housing prices. Our findings clearly show that the effects of mixed land use on apartment and general housing prices are different. Specifically, mixed land use decreases apartment prices, whereas it increases general housing prices. The results suggest important policy implications that mixed land use policy should be differentiated by the two different housing types such as apartment and general housing.

This study analyzed profitability in pros and cons of owners about Garibong Urban Redevelopment District. Logistic Regression Model was performed as step 1 to analyze determinants that affect pros and cons, and a data-mining technique called decision tree analysis (CRT) was done as step 2 to investigate the decision tree structure. As a result of analysis, factors that affect pros and cons of owners were found to be residential location as personal characteristic, rent income, property and share of expense as economic characteristics, and building use as physical characteristic. On the contrary, age and physical characteristics such as land area, frontage condition and aged building did not show effects. Among determinants analyzed, change of residential location had greatest influence on change of decision, and owners placed priority on payment of additional share of expense when deciding pros and cons. Summarizing the results, whereas criteria for designation of urban redevelopment districts are physical factors such as deterioration and frontage condition, owners made project decision based on residential and economic characteristics. Many redevelopment districts were designated without consideration on characteristics preferred by owners.

The purpose of this study is to identify a relationship between sensible temperature in summer and land cover type. Through this, it is possible to form strategies for land use and urban planning which can reduce sensible temperature in summer. To achieve this, multiple regression analyses were conducted based on 80 of the automatic weather station (AWS) point of atmospheric temperature, sensible temperature, and land cover at a radius of 500 m around the AWS point. The heat index was used for measuring sensible temperature. Moreover, considering that abnormally high summer temperature phenomena such as tropical nights have different characteristics depending on the time of the day, air temperature and sensible temperature in daytime and night time were studied separately. The results of the analysis showed that an increase in green area was effective in lowering both atmospheric and sensible temperature. Unlike atmospheric temperature, for lowering sensible temperature in summer nights, a decrease in transportation area was more efficient than an increase in green area. On the other hand, for atmospheric and sensible temperatures during summer days, it is efficient to not just keep expanding green areas, but to also have large and nearby patches of non-urban area.

This study examines the association between neighborhood environment and walking satisfaction using the Seoul Survey 2013. We use the multi-level models that examine the impacts of neighborhood environment on walking satisfaction, controlling for household and neighborhood effects. Analysis results indicate that demographic and socioeconomic characteristics are very important variables for walking satisfaction. Regarding neighborhood environments, subjectively measured neighborhood environment variables such as crime risk, noise, air pollution, parking problem and other neighborhood environment variables are statistically significant factors of neighborhood walking satisfaction. In particular, walking safety and amenity variables are very important for pedestrians’ walking satisfaction. Some neighborhood physical environment variables such as railway or highway pass are also significant. Such border vacuum variables show negative associations with walking satisfaction. Lastly, land use and road network variables do not show any statistical significance to the level of pedestrian’s walking satisfaction. We summarize key findings and discuss policy implications to improve neighborhood walking satisfaction in Seoul, Korea.
