The purpose of this study was to examine the role of consumers' self-image and pursued-image of clothes on the clothing purchase decision making according to the location. Data were obtained from a questionnaire filled out by 575 women living in Seoul and Jechon. For data comparative analysis, paired t-test, t-test, factor analysis and multiple regression analysis were used. The results of this study are as follows: 1. There were significant differences in self-image and pursued-image in terms of clothing purchases between women who live in Seoul and Jechon residents. 2. Demographic variables influenced to the self-image and pursued-image of clothes factor. Among them, size of the city was the most important factor which influence to the clothing purchase behavior. 3. Self-image, pursued-image of clothes, problem recognition and evaluative criteria factors significantly differed between Seoul and Jechon residents. In two cities, problem recognition factor which was arisen by external stimulus and all of the evaluative criteria factors showed significant differences. 4. When the cities were partitioned by size(large and small city), the influence of self-image and pursued-image of clothes on the clothing purchase behavior showed different phases. Generally, self image and pursued-image of clothes were more important to various problem recognition and evaluative criteria factors in large city(i.e. Seoul) than in small city(i.e. Jechon). However economic rational factor was the exception.

$PM_{2.5}$ samples were collected from December 2005 through November 2007 in two cities including Chuncheon and Seoul in order to investigate the characteristics of carbonaceous aerosol. The average $PM_{2.5}$ concentration in Seoul ($43.2{\mu}g/m^3$) was approximately 1.2 times higher than that measured in Chuncheon ($36.1{\mu}g/m^3$), however there was no statistical difference on $PM_{2.5}$ concentration between those two cities. Backward trajectories were passing through Seoul area before arriving Chuncheon for about half of the samples, and $PM_{2.5}$ largely increased in Chuncheon when back-trajectories originated from Seoul area. Total carbon (TC) was calculated as sum of OC and EC, contributing 20.5% and 29.2% to total $PM_{2.5}$ mass in Chuncheon and Seoul, respectively. The average ratio of secondary organic carbon (SOC) to total OC was 40% at both sites, and the highest SOC concentration was observed in summer probably due to enhanced volatilization of organic species and active photochemical reaction. J value was calculated to determine if acidic condition affected the increase of secondary organic carbon. In both Chuncheon and Seoul SOC/OC ratios were fairly enhanced when J<100% of acidic condition.

The internal structure of gateway city is to be influenced by the external relations. The purpose of this study is to examine the transportation impacts on the spatial characteristics of gateway cities in the Geum River basin, Korea. The changes of the transportation is classified by the commodity, the rice flow, and the functions of the gateway are examined in Gunsan-Si and Ganggyeong-Eup. Major findings of the study are as follows. First, the water and land transports in the gateways are connected or not. In the flow of the rice, the Gunsan gateway is connected, while the Ganggyeong is not. The difference is reflected in the location of the port and railway station. In the flow of marine products and salt, the Ganggyeong gateway is connected, while the Gunsan is not. Second, there had been separated or not in the location of the ports of the marine products and the rice. They are separated in the Gunsan, while not separated in the Ganggyeong. The results imply that there are to be difference between the two ports after the gateway of rice.

Objectives: The purpose of this study was to provide policy directions for air pollution reduction by analyzing the variation in the characteristics of air contaminants around the Gyeonggi Province area. Methods: The data used in the study was obtained from air quality monitoring stations operated by the Gyeonggi Provincial Government. The target area was the air quality management area of the Gyeonggi Province region. Results: The concentration of $PM_{10}$ (particles measuring $10{\mu}m$ or less) in 2009 was $60{\mu}g/m^3$, which has been reduced by about 2.7% per year after improvement countermeasures were emplaced. The air pollution control policy was especially more effective for coarse particulate matter (CPM, $PM_{10-2.5}$). The improvement of $NO_2$ pollution was generally very low, especially in cities which had considerable automobile traffic. The concentration of $SO_2$ pollution was rapidly improved in industrial areas, but did not show any difference for multiple and general cities. The predicted concentration of $PM_{10}$ for 2014 based on the trend over 2001-2009 was $53.4{\mu}g/m^3$, which fails to meet the target concentration of $40{\mu}g/m^3$. The predicted concentration of $NO_2$ shows a very low probability of achieving the target concentration of 22 ppb, and thus the current improvement of air quality has proven unsatisfactory. Conclusion: Air pollution control policy should be enforced according to regional pollution characteristics in order to obtain maximum effectiveness in improvement.

The purpose of the study is to analyze and to clearly put more understanding on the current LED sky screen structures located not only in some cities of Korea but also in those of other countries which have been running the large-scaled LED sky screen, which is also called the LED canopy. In addition, this research is to also focus on the availability or possibility of the social role for the large-scaled LED sky screen to make great contributions to the local economic development of the relevant cities which are currently running their large-scaled LED sky screens, in terms of facility, contents and strategy, respectively. For this research, 4 large-scaled LED sky screens located in both domestic and foreign countries such as Suzhou Sky Screen in Suzhou city of China, Fremont Street Experience VIVA VISION in Las Vegas of the States, the Palace Sky Screen in Beijing of China, and Yeosu Expo Digital Gallery Sky Screen in Yeosu city of Korea, respectively, have intensively been dealt with for research, in terms of the features of their facility aspects.

The development of Korean urban geography can be divided into several stages including initial stage, transition stage, and maturation stage. If this trend persists, it can be expected that it would turn into the matured stage. This paper intended to recall the research trends from 1960 to 2012, focusing on 686 papers and 177 books published during the last 62 years, and investigated by research areas, study regions, methodologies, and journals in relation to urban geography. Although increasing number of urban geographers has made mutual relationship more complex and diverse, no signs of school formation have yet been seen in Korean urban geography. Large portions of papers have concerned about Seoul Metropolitan Region for their study regions. There have been diversified trends of oversea studies away from the US cities to other cities in various countries. Also, quantitative studies have been increasing their weight since the 2000s. Moreover, articles on the Journal of the Korean Urban Geographical Society have been far surpassed in its number.

This study aims to find the association between community scales and perceived community family-friendliness among parents with young children. Communities were identified into three groups: metropolitan, small and medium-sized cities and rural, according to the degree of urbanization. The data were drawn from a sample of 1,038 parents who had at least one pre-school child. The data were analyzed by frequencies, means, GIS, ANOVA, and multiple regressions. This study compared the level of community family-friendliness both at the 'dong' and 'si' levels after controlling for the individual and household characteristics of the respondents. The findings of this study are as follows. First, after controlling for individual and household factors, the level of perceived community family-friendliness differed by the community scales. The parents in the small and medium-sized cities had higher scores on community family-friendliness than their counterparts in metropolitan communities. And parents in rural communities received had lower scores in community family-friendliness than those in metropolitan communities. The results also showed similar patterns for the 'dong' and 'si' models. While job and housing type were associated with the perceived family-friendliness of the community, other characteristics such as sex, age, educational level, monthly household income and home ownership were not.

This study uses a continuous autoregressive (CAR) model to analyze daily average temperature in six Korean metropolitan cities. Data period is Jan. 1, 1954 to Dec. 31, 2010 covering 57 years. Using a relative long time series reveals that the linear time trend components are all statistically significant in the six cities, which was not shown in previous studies. Particularly the plus sign of its coefficient implies the effect on Korea of the global warming. Unit-root test results are that the temperature time series are stationary without unit-root. It turns out that CAR(3) is suitable for stochastic component of the daily temperature. Since developing suitable continuous stochastic model of the underlying weather related variables is crucial in pricing the weather derivatives, the results in this study will likely prove useful in further future studies on pricing weather derivatives.

The use of technical proposal tendering has been expanding recently with the aim of effecting cost reduction, quality enhancement, technological development and value realization centered on multifunctional administrative cities, innovation cities, and the Yongsan relocation project. In line with the increasing interest towards life cycle cost improvement measures as an important evaluation category concerning technical proposal tendering, efforts in preparing measures that can execute the security of credibility and objective evaluation concerning architectural life cycle cost are being made. However, problems such as lack of applicable cases of design development and detail design, distortion of initial construction costs concerning the original plan, combination of constant price and current price, the ambiguity of the calculation standards between tendering corporations, inaccuracy of terms, and insufficient compositional formats concerning life cycle improvement measures are being cited. Accordingly, this study sought to propose a measure to improve the compositional guidelines, format, and standards so that a systematic life cycle cost evaluation can be executed for the reliable distinction of each participating corporation, enhanced credibility and objective evaluation of the life cycle cost improvement measure for technical proposals.

The purpose of this paper is to conceptualize the brand of tourism resources and examine the effects of brand equity on brand loyalty focusing on the brand of tourism resources in cities and counties level. To this end, we reviewed the literatures and analysed 410 surveys from the 8 provinces. The results show that brand awareness and brand image of tourism resources have significant effects on brand preference, and brand awareness, image and preference have effects on brand loyalty measured by revisit and recommendation intention. However the one of most important results is the brand equity(awareness, image, preference) has partially significant effects on brand loyalty under the effects of visitor's satisfaction. Additionally, the positive effect of brand awareness on brand image is examined. More specific results and implications are provided.
