The purpose of this paper is to examine the effect of management policy by looking at changes in land fragmentation in non-urban areas. This study defines and analyzes the phenomena of land fragmentation and sprawl in non-urban areas, which are critical in the policy. We have examined changes in land patterns before and after the period when the Segmentation of Control areas policy was enforced. We selected Hwaseong City as the subject of the research and then focused on the Used-Areas, one of the seven categories in the Land Cover Maps of 2001, 2007, 2009, and 2014, to examine the changes in land-cover fragmentation patterns. Fragstats program was used to quantitatively analyze the fragmentation pattern of land. Through a literature review, we selected seven indices related to (1) the size and the number of land patches, (2) the patch shape and complexity, and (3) the isolation and connection caused by fragmentation. Quantitative values were used to investigate the changes in value before and after 2008. The indices related to the size and the number of the land patches in the Used-Areas show that there were more subdivisions and smaller developments after 2008 than before. The shapes of patches became more complex after the policy period but one thing to note is that the values don’t have a dynamic range. The values of the indices related to isolation and connectivity indicate that more patches were isolated and had less connection in 2009–2014 than in 2001–2007. These results show that sporadic development of small scale has continued to occur even after the implementation of the Segmentation of Control areas policy.

This study aims to empirically assess the effects of heat-wave adaptation policies on the incidence of heat-related illnesses. The study period is the summer of 2018, in which the temperature in South Korea reached a record high. We tested the four generalized linear models, including the Poisson, negative binomial, zero-inflated Poisson, and zero-inflated negative binomial regressions. After fitting these with the heat-related patients count data, we selected the zero-inflated negative binomial analysis for its superior goodness-of-fit. The results suggested that temperature increment is associated with the number of patients with heat-related symptoms regardless of whether or not a heat warning went off. Further, the empirical results demonstrated that the increase of both urban forests and cooling shelters in residential areas are associated with lower incidences of heat-related illnesses. Given that climate change is expected to increase the intensity and duration of heat waves, it is necessary to establish better systems for both weather prediction and information delivery in implementing heat warnings. Furthermore, this study suggests that green land use planning and heat-illness prevention programs could be viable measures for preventing adverse effects on human health from extreme weather events.

The shutdown of the Gaeseong Industrial District in February 2016 caused huge losses for Strategic Investment Companies( SICs) which invested in North Korea. SICs were forced to obey the sudden shutdown decision of the government. Even though they were not at fault, they didn't get adequate compensation for damages. Hence, SICs have failed to trust the government. As a result, financial institutions, as well as SICs, perceive that the inter- Korean economic co-operation is an unreliable business. In this situation, an attempt has been made to find an appropriate investment structure in North Korea. Real estate investment trusts(REITs) can be an attractive financial vehicle to prevent investment loss. Also, REITs can be a readily acceptable model because REITs do not require North Korea to greatly change its laws and institutions. The following steps can be undertaken: SICs invest loaned funds in REITs and provide financial institutions with stocks as the collateral. REITs make a lease agreement with the North Korean authorities, build factories, and rent those factories to local subsidiaries established by SICs. If the inter-Korean relationship worsens, SICs will ask the Inter-Korean Cooperation Fund to buy the stocks of the REITs of their own. SICs repay the loans with the stock sale price. Moreover, the investment structure using REITs will provide the creditors with a means of payback by auctioning off the stocks of the REITs. Therefore, it can be seen that REITs are reliable investment vehicles that promote investment activation and fund-raising from the investors’ point of view.

This study explores the wider economic effects of transport infrastructure investment and provides empirical evidence regarding their magnitude and patterns at the micro level, using Seoul and the Seoul region as cases. Based on the classification of the economic effects of transport infrastructure investment presented by Venables, the study focuses on three aspects of economic performance: productivity, employment, and land values. Specifically, three analyses have been carried out to determine the wider economic effects of transport infrastructure investment and its user benefits. For each of these analyses, a separate empirical strategy was developed, with various spatial and instrument variables created and regression models developed. A range of accessibility indicators was also constructed to capture changes in accessibility resulting from transport infrastructure investment. It is found that transport-induced agglomeration effects are positive in the Seoul region, and their magnitude is in the range of elasticities reported in previous studies. I also found that transport infrastructure investment leads to an increase in a firm’s productivity through the mechanism of agglomeration. The second analysis shows that transport-induced labour accessibility is one of the key determinants of job growth, with relative accessibility having greater effects than absolute accessibility in the Seoul region. The third analysis shows that rail transit investment has not only resulted in a reduction in travel costs, but also generated wider economic benefits, such as increased employment opportunities. The magnitude and pattern of the effect of rail transit investment differs across different types of land uses and benefits vary with the distance to a rail station. The overarching conclusion is that well-designed transport infrastructure investment generates wider economic benefits in addition to the user benefits. Therefore, transport infrastructure investment should be considered as a planning tool to address various urban and regional issues and strategy for economic revitalisation.
