The aim of this study is to analyze the general satisfaction of the commercial areas near Cheonan central bus terminal and the rail-station and to extract various environmental factors of the city center which give effect to the user satisfaction of commercial area. As the result of the analyses, the environmental factors of the city center make a difference between the commercial areas of Cheonan central bus terminal and of the station in the aspects of user satisfaction. The user satisfaction of the commercial areas is appeared highest in 'comfort of walking environments' and 'convenience of commerce business transaction' which were environmental factors of the city center. For reactivation of the commercial area near Cheonan rail-station are needed improvement of walking environments and relocation of facilities as complex mall and bank etc.

In regard to the growth and development of Innocity from improvements in Innocity settlement environment, this research examines the level of satisfaction of Innocity settlement environment to propose a political implications. We deduced the main cause of settlement environment satisfaction by performing logistic regression on the public institution employees level of satisfaction in respect to 4 Innocity characteristics?six physical properties, three social properties, five facility properties, three economical properties?and three general questions. As a result, the greatest factor of settlement environment was physical properties, such as natural environment and scenery, residential environment, availability of diverse uses in the surrounding area, and access to public transportation. In addition, social characteristics (relationships with neighbors), and facilities (availability of industrial, research and educational facilities) were also significant. This research provided political implications for future Innocity settlement environment improvements despite limiting factors such as residents' perception and limited surveyed sites.

This study aims to provide primary data for R&D on rollator-walking frame through researching the usability test of the rollator-walking frame and the effect of rollator-walking frames on the lives of senior citizens. This study surveyed 60 senior citizens living in Sungnam City in South Korea. As the result of the usability test, we can find users' dissatisfaction with the folding, weight, shape of backrest and material of chair. The survey shows that the frequency of outdoor activity is mostly increased by the convenience of product. However, the inconvenience while using facilities, such as elevators or public transportations, gave a significant impact on the decrease in going out experiences. Therefore, for better outside lifestyle of senior citizens, it is important to improve the function of the product, however, we need to make improvement of urban infrastructure.

This study aims to analyze the spatial patterns of intellectual property across various regions through an in-depth analysis of intellectual property trends and their influential factors. While there's an overall upsurge in intellectual property applications in the Seoul metropolitan areas, a more detailed inspection reveals divergent patterns based on the type of intellectual property - with patent rights primarily increasing in certain non-Seoul areas and trademark rights seeing a rise predominantly within Seoul. Our findings also suggest that the growth in intellectual property applications correlates positively with improvements in public transportation accessibility, expansion of knowledge-based service industries, and a rise in large enterprises, although the relationships vary by intellectual property type. These results indicate the significant influence of geographical factors and industrial structures on knowledge-generation activities, thereby suggesting a need for region-specific policies to bolster these capacities.

The world's major cities operate public rental bicycle systems to complement the existing problems of public transport in the city. Disclosing the rental history data in Daejeon has opened new analytical possibilities. In this paper, we proposed a method to analyze the data using the visualization. We found a positional feature of the station according to the bicycle usage. In addition, we examined the bicycle usage patterns according to the time/day/month. On the other hand, the usage patterns between each of the bicycle stations were identified through a path analysis. The specific objectives were identified through each stop destination ratio analysis. Based on these data, we suggest a direction of Daejeon public bicycle rental system development.

This paper analyzes factors affecting rail transit ridership at urban rail stations of the Daegu Metropolitan City in 2011. Rail transit ridership is analyzed by dividing weekdays and weekends in order that their differences may be observed. The data used in this study includes various explanatory variables, such as floor area which was collected from building ledger and GIS cadastral map, number of bus routes(line) possible to transfer from urban rail transit, number of students enrolled in middle and high schools, and universities located in access areas of rail transit. For this study, multiple regression models are estimated including various explanatory variables affecting rail transit ridership of weekdays and weekends. From the study, the number of statistically significant explanatory variables and the relative effect of each variable are shown to be different between weekdays and weekends.

Seoul Metropolitan Urban Railroad has an undecided route that does not estimate the passenger transportation route. For this reason, the fare of the urban railroad is calculated by the assumption that passengers pass through the minimum distance. Therefore, if a transfer station on the urban railroad is added, the trip shortest distance could be decreased and the fare also reduced. In this study, this phenomenon defines the fare paradox(Shin, 2022) and estimates the impact of the fare paradox by opening the GTX-A. For this purpose, a scenario before and after the opening of the GTX-A has been established, and an additional fare has been estimated by proportional planning of the Seoul Metropolitan Integrated Distance Based Fare Policy. Fare Paradox was analyzed to about 0.024 % of daily income. It is expected to be used as a plan to determine a rate policy, such as the establishment of a GTX-A, B, C, D, and a light rail line.

The purpose of this study is to analyze city's built environment that have influence on residents' health in the 40 small and medium-sized cities. In the study, landuse, urban form and facility accessibility of cities and other socio-demographic variables were used as explanatory variables, and a statistical analysis was carried out by applying multi-level analysis. Analysis shows that a high level of population density lower the obesity, and a high level of landuse-mix have a positive effect on EQ-5D & hypertension. In terms of urban form and facility accessibility, residents show a high level of obesity in an environment where roads are closely connected and access to bus service is bad. Finally, as more access to open space have a positive effect on EQ-5D. Therefore, landuse-mix, access to public transportation and open space should be used for planning factors to make a health improvement plan in cities.

This paper explores key factors affecting taxi travel using global positioning system(GPS) data in Seoul, Korea, considering spatial dependence. We first analyzed the travel characteristics of taxis such as average travel time, average travel distance, and spatial distribution of taxi trips according to the time of the day and the day of the week. As a result, it is found that the most taxi trips were generated during the morning peak time (8 a.m. to 9 a.m.) and after the midnight (until 1 a.m.) on weekdays. The average travel distance and travel time for taxi trips were 5.9 km and 13 minutes, respectively. This implies that taxis are mainly used for short-distance travel and as an alternative to public transit after midnight in a large city. In addition, we identified that taxi trips were spatially correlated at the traffic analysis zone(TAZ) level through the Moran's I test. Thus, spatial regression models (spatial-lagged and spatial-error models) for taxi trips were developed, accounting for socio-demographics (such as the number of households, the number of elderly people, female ratio to the total population, and the number of vehicles), transportation services (such as the number of subway stations and bus stops), and land-use characteristics (such as population density, employment density, and residential areas) as explanatory variables. The model results indicate that these variables are significantly associated with taxi trips.
