    Suitability Analysis of Optimal PM Monitoring Stations Using Kernel Density Function and PCA

    Jeong, Jong Chul | 2020, 105() | pp.3~14 | number of Cited : 0
    Abstract PDF
    For optimal new PM(Particulate Matter) monitoring locations, it is important to consider the spatial distribution between monitoring station and user along with the accessibility. This study used spatial analysis to analyze the shortest distance among the centers of administrative dong and PM monitoring stations to show the influence of PM monitoring stations. In addition, this research suggested the new PM monitoring location through distance analysis and kernel density estimation of PM monitoring stations and public facilities such as community service center. This study proposed the method to select new PM monitoring station from an area outside the scope of the existing PM monitoring station, without showing redundancy with the existing network. Then the principal component analysis was performed in order to determine the priority PM monitoring stations that have a higher value for environment variables and kernel density estimation related to PM. The new PM monitoring stations suggested in this study will provide the more improved PM measured value service for users than the conventional PM monitoring network.

    Characteristics of Child Friendly City Planning of Germany and Their Implications for Korea

    Lee Sunju | Kim, Sung Gil | Frank Eckardt | 2020, 105() | pp.15~30 | number of Cited : 0
    Abstract PDF
    Currently, ninety-six local governments in Korea are participating in UNICEF’s Child Friendly City (CFC) project. UNICEF emphasizes the role of urban planning to realize a CFC; however, Korea only focuses on the welfare of a CFC. This study aims to identify the characteristics of Germany’s CFC initiative and to consider the implications for establishing a CFC in Korea. A literature review was used in this research to evaluate the importance of a CFC. Herein, we suggest three implications based on the German CFC initiative to establish a domestic CFC. First, there is a need for the government to develop appropriate urban planning techniques. Second, it is necessary to consider the rights of child participation, legally. Third, a CFC initiative needs to be divided into “child friendly city planning” and “youth friendly city planning.” The suggestions of this study will become the key factors to establish a child-friendly environment in Korea in the near future.

    Comparison of Production-Based Emissions and Consumption-Based Emissions of Particulate Matter in Northeast Asia

    Moon Seung-woon | 2020, 105() | pp.31~48 | number of Cited : 0
    Abstract PDF
    This study assesses the consumption-based PM emission, and compares production-based accounting and consumption- based accounting of trade and embodied PM for three Northeast Asia countries - Korea, China, and Japan. The result shows that 22.00% of Japna’s and 36.02% of Korea’s consumption-based PM emission are generated in China. In other words, China is the largest emitter of PM, but much of PM emissions of China come from consumption in Korea and Japan. In addition, the Chinese industry has a higher pollution intensity than the Korean and Japanese industries, suggesting that the Pollution haven hypothesis has been proven. Consumption-based accounting can quantify the responsibilities of Korea and Japan for PM generated in China, and this results can be considered in cross-border negotiations for abatement of PM. Abating PM in Northeast Asia requires cross-border cooperation, and consumption-based accounting can provide important scientific evidence. The results of this study may provide appropriateness and basic material for international cooperation.

    A Study on the Estimation of Impact by High-Speed Railway Surcharge Considering Marginal Cost and Demand

    Lee, Jonghoon | Shon Eui-Young | 2020, 105() | pp.49~64 | number of Cited : 0
    Abstract PDF
    In 2015, the Honam High-Speed Rail opened and the Korean High-Speed Rail was completed. High-speed rail was expanded and demand continued to grow. Railroads require a lot of investment and operating costs. However, in the case of South Korea, high-speed rail fares are calculated based on government policy. For these reasons, high-speed rail operating losses are higher than operating income, and debt continues to grow. These issues are likely to be passed on to the social burden, and it is time to consider different ways to secure high-speed rail alternatives and financial health. In this research, we proposed a method to improve traffic efficiency, focusing on the on-demand distribution of high-speed trains through demand analysis of high-speed trains and conversion to alternatives. We used Ramsey pricing to provide 15% and 30% surcharge for demanding weekend users. As a result, it was confirmed that the efficiency could be improved by switching demand to other means.

    Comparison of Survival Rate in Food Service Industry between Growing Commercial Districts and Declining Commercial Districts of Seoul

    LEE DONG HYUN | Lee Jae Kyung | Cheon SangHyun | 2020, 105() | pp.65~84 | number of Cited : 1
    Abstract PDF
    Commercial districts grow and decline for a variety of reasons, such as urban redevelopment and gentrification, over time, which affect the survival of commercial facilities in the districts When analyzing the survival and the closing of commercial facilities in commercial districts, one should consider temporal changes of the commercial districts : growth and decline. This research analyzes and compares the survival and the closing of commercial facilities that are located in differing types of commercial districts that experience growth vs. decline , focusing on the restaurant industry in Seoul. To this end, we classify growing- and declining- commercial districts based on the Commercial area Vitality Index. Second, we analyze the difference in survival rates by the types of commercial districts. The results of this study are as follows. First, we divided Seoul into five types of commercial districts based on the Commercial area Vitality Index . Second, comparing the survival functions of commercial facilities operating in the differing types of commercial area, we confirmed that the restaurant industry has the highest survival rate in areas where commercial activities are active and have become stronger over time.

    Impact of Local Air Pollution on Electric Vehicle Adoption in Korea

    Park, Jiyoung | Kim Ja In | 2020, 105() | pp.85~100 | number of Cited : 0
    Abstract PDF
    Promoting policies on eco-friendly cars is a major policy tool to reduce air pollution in cities. This study analyzed the consumer’s purchase intention on electric vehicles and how air quality problems such as particulate matters affect their purchase intention using ordered logit model from a survey with 918 drivers in Korea. The results show that major factors that significantly affect the purchase intention on electric vehicles are the interest in new technologies, the concerns on environmental problems issues, and the awareness of characteristics of electric vehicles. Especially regarding air quality issues, consumers who are more interested in climate change or environmental pollution are more likely to purchase electric vehicles as they recognize the importance of activating electric vehicles as a solution to particulate matter. In order to spread electric vehicles in the future, it is important to actively promote electric vehicles that can improve consumer awareness of eco-friendly electric vehicles and to make technical and policy efforts to improve the eco-friendly nature of electric vehicles such as expanding renewable energy.

    A Fundamental Study for Urban Canopy Layer Analysis and Application: Focusing on Seoul Metropolitan Area Urban Weather Service Domain

    Seung Man An | Do-Hyoung Kim | Seon-Ok Hong and 1other persons | 2020, 105() | pp.101~120 | number of Cited : 0
    Abstract PDF
    The purpose of this study is to perform Seoul Metropolitan Area (SMA) urban weather service domain building cluster analysis in the urban canopy modelling framework and to develop urban building cluster management application. Major results show SMA urban weather service model domain(7,114㎢) covers 7% of the national territory, 1/5 buildings in the nation located, which has 1/3 of the national building total volume area. We found a relation between urban canopy parameters (UCPs) with land use zone type and urban temperature such as LST. Quantile 5 class roughness length group mean LST showed a gradual increase as building clusters become higher but most high group showed about 0.5℃ decreased value. In addition, we found South-North directional frontal area fraction shows 10 % higher value than East-West, which is mainly due to the unique Korean apartment culture and residential preference. Building cluster study is important for major urban issues such as climate change adaptation, air quality, revitalization, green new deal, smart eco-city. Hence, as a further project, we propose building cluster-based vertical information (indicator) development and monitoring development study should follow.

    The Effects of High-Tech Specialization on Intra-Regional Changesin Income and Poverty

    Kim, Chanyong | Jae Won Kim | Up Lim | 2020, 105() | pp.121~144 | number of Cited : 0
    Abstract PDF
    This study aims to examine the effects of high-tech industries on dynamic changes in regional income and poverty using a regional-level data from the Local Area Labour Force Survey from 2010 to 2015. High-tech industries often considered as a potent driver of complex inequality by class and gender. Thus, this study empirically analyzes the role of high-tech industries on the wage growth of workers with high- and low-levels of educational attainment and changes in poverty rate. The empirical analysis is based on the regional-level data from the Local Area Labour Force Survey. Results show that the benefits from the specialization of high-tech manufacturing industries are insufficient to increase the wage earnings of the disadvantaged labor groups and reduce the poverty rate. On the other hand, a high proportion of employees in high-tech service industries positively affects the wages of low-skilled workers and poverty reduction. This study presents challenges for policymakers who are interested in linking local economic growth with disadvantaged groups.

    Analysis Method of Disorderly Land Use behavior in Non-Urban Area:Focused on Land Use Diffusion and Mixture

    Kim Seong Hee | Kim Dongkun | 2020, 105() | pp.145~164 | number of Cited : 0
    Abstract PDF
    In order to manage land use in non-urban areas, a method of measuring the degree of disorderly development must first be provided. In this study, the index measuring the spatial distribution of land use and the index measuring the mixing degree of land use were reviewed. Also, as a complementary technique to the existing methodology, the method of comparing and analyzing the characteristics of the surrounding land use of the land where development took place was newly proposed. According to the case analysis of Hwaseong City, the land use diffusion and the mixed measurement index show differences between areas. In particular, a graph that was analyzed in conjunction with Moran’s I, which means the degree of land use diffusion, and LUMI (Land Use Mixture Index) shows that which areas are concerned about disorderly development. The analysis of land use characteristics in the surrounding areas indicated deviations by land use purpose and region. Basically, residential facilities and factories tended to be separated, but Bongdam-eup and Paltan-myeon tended to be adjacent. These areas are relatively more likely to face disorderly development problem. This Analysis methodology will help establish policies for managing non-urban areas, such as development permit criteria or site selection for growth management plan.

    Using mobile Big Data in Permitting the River Space Use: Focus on Encroachment of Convenience Facilities in the Water-Friendly Space

    Jongso Lee | Lee Sangeun | 2020, 105() | pp.165~176 | number of Cited : 0
    Abstract PDF
    Governments have designated and operated water-friendly spaces in rivers in order to offer opportunities for refreshment and leisure to citizens. However, there are difficulties in providing convenience facilities for those spaces, mainly because of a conservative tradition related to the river space use permit. In this regard, this study present a novel method to estimate the adequate number of toilets and parking lots, as examples of convenience facilities, which citizens have often asked to provide. This study suggests two-steps approach: first, estimating statistically the rough number of convenience facilities from the key design variable, i.e., number of visitors; second, adjusting the number based on auxiliary design variables, i.e., areas of spaces and per capita visiting distance. Moreover it is found that mobile big data could be a good data source for building the statistical equation and investigating design variables for each water-friendly space. Finally, it describes a need for further studies and importance of managers’ and practitioners’ participation in improving the proposed method.

    Assessing the Economic Value of Water-friendly Space by Contingent Valuation Method and Mobile Bigdata Analysis

    Oh MyoungJin | Shin Jungwoo | Lee Sangeun and 1other persons | 2020, 105() | pp.177~194 | number of Cited : 0
    Abstract PDF
    Water-friendly spaces in national river are designated places by the Government to provide rest and leisure to public. For efficient designation, maintenance, and management of them, it is necessary to calculate the economic value of each water-friendly space. This study calculated the economic value of 297 water-friendly spaces nationwide by combining the number of actual visitors derived from Mobile Bigdata analysis and the willingness-to-pay(WTP) of each household derived by the survey conducted for this study and contingent valuation method. The estimated result for annual WTP per household for the neighborhood-type was 9,774 KRW and 5,806 KRW, and for the community hub-type, it was 8,452 KRW and 5,398 KRW, within and outside the local administrative boundary respectively. By combining this result and the number of visitors of each water-friendly space derived from the Mobile Bigdata analysis, the median annual economic benefit for each water-friendly space was calculated as 33.7M KRW for the community hub-type and 21.1M KRW for neighborhood-type.

    A Study on the Establishment Process and Cultural Role of Gunsanjwa during the Japanese Colonial Period

    Kim Namseok | 2020, 105() | pp.195~214 | number of Cited : 0
    Abstract PDF
    Gunsanjwa is a theater established in Gunsan during the Japanese colonial period, and was a representative local theater that grew up with the floating population and commercial capital of Gunsan. Since Gunsanjwa was a theater located in an area separate from the Gyeongbu Line railway, there were many disadvantages in supplying and distributing theater/movie/performance content. However, Gunsanjwa was a theater where it was possible to perform tours to Honam(Jeollado), and it also had a relative advantage that it could be occupied exclusively if it aimed for the route(the western part of Korea). As a result, Gunsanjwa was able to operate as a theater that attracted attention from the early days. In order to study Gunsanjwa, it is necessary to understand not only the aspect of the theater, but also the geographical situation, the size of the city, and the transportation network(railway network) at the time. In order to examine the reality and characteristics of Gunsanjwa, this study aimed to synthesize data on maps, newspaper articles, performance photos, and related persons at the time. In addition, this study attempted to analyze the location, scale, facilities, managers, and performance contents of Gunsanjwa based on this.
