This study analyzed the time-varying relationship between the housing trading market and housing jeonse market. As a result of the time-varying Granger causality test, the causality of the jeonse price on the sales price was clear in the mid-1990s, and it was analyzed that there was causality after 2010. The causality of the sales price to the jeonse price was observed at some point in the 1990s, but what was commonly observed in all models was analyzed after the 2000s. After 2010, the analysis showed that there was bidirectional causality between the sales price and the jeonse price. As a result of the analysis of the time-varying impulse response function between the sales price and jeonse price, there was confirmation that the shock of the increase in the sales price was generally induced by a reaction to an increase in the jeonse price during the previous period, and that this impact differed depending on the time period. On the other hand, jeonse price leading to increased shocks on sale price was not found before 2000, and while this influence intensified after 2010, there was confirmation that the impact was greatest around 2020.

This study analyzes cases of culture-led urban regeneration as applied to the functional and spatial transitions of port cities. It explores the relationship between ports and urban growth, and connects urban design theories together to investigate the emergence of culture-based urban regeneration. It establishes an analytical framework by synthesizing prior research on local assets, urban regeneration, and waterfront redevelopment. As a case study, the waterfront renewal projects of Granville Island in Vancouver and HafenCity in Hamburg are analyzed based on port city attributes and urban design perspectives. According to the results of the analysis, these port city regeneration projects converted restricted port spaces into open public spaces. Waterfront regeneration of port cities focused on the spatial transition into public space, thereby sharing and consuming the intangible cultural values surrounding the waterfront. It differs from the traditional use of port areas, which was production-based — mainly concerning physical production and the economy — and closed to civilian access. Both cities have improved accessibility to their declining post-industrial port areas, transforming them into public spaces that produce and consume cultural capital. Granville Island successfully revitalized its industrial hinterland into a hub of culture and entertainment with high accessibility for citizens. HafenCity transformed the dilapidated dock and warehouse areas of the port into a high-density mixed-use area with waterfront cultural resources. This research presents a distinctive approach from existing studies that focus on hierarchical structures and waterfront developments in port hinterlands, offering valuable insight

Particulate matter (PM10) that threatens human health has now become a social disaster. The urban form and physical characteristics are important factors that determine the dispersion of air pollutants. The aim of this paper is to explain the relationship building coverage ratios and the concentration of PM10 in urban street canyons where the concentration of PM10 is high. For this study, ENVI-met software was used after setting alternatives according to the change in the building coverage ratios and aspect ratio. Multiple regression analysis was performed with the concentration of PM10 as a dependent variable, building coverage ratios as an independent variable, and wind direction, wind speed, and air temperature as control variables. As a result, it was found that the concentration of PM10 increased as the building coverage ratios of the street canyons increased. This study suggests the change of the concentration of PM10 according to the building coverage ratios in street canyons and suggests that building coverage ratios should be considered in urban design.
