After the Great East Japan Earthquake 2010, earthquakes of magnitude 5.0 or higher occurred in Gyeongju and Pohang, shocking the public, and residents near the epicenter suffered great confusion and inconvenience in evacuating due to the unannounced earthquake. In the case of open spaces, such as parks and green areas, disaster prevention capabilities shall be established that can be used as a place of evacuation in the event of a disaster. But in Korea, which is perceived as relatively safe from natural disasters, most of them perform only basic functions such as rest, entertainment and health care. Therefore, It will analyze the status of the open space in Pohang, which was severely damaged by the earthquake, and conduct a survey on citizens who have had evacuation experience in the event of the actual Pohang earthquake, to analyze whether the open space served as a shelter in the event of a disaster, and suggest supplementary measures. In addition, the study highlighted the disaster prevention function when establishing the park green area policy in Pohang, suggesting and proving that the park green area is an essential urban infrastructure to protect the lives and safety of citizens in the event of a disaster.

Technological innovation is crucial to the long-term survival of firm, regions and country. Among various factors that affect a product innovation, a substantial body of literature have highlighted the contribution of networks to product innovation in large-sized firms as well as small- and medium-sized firms. However, although the role and importance of networks driving product innovation by firm size are different, researchers that have investigated the relationship among innovation, networks and firm size are very few. In this study, we empirically analyze the effects of networks on product innovative outputs in manufacturing firms using negative-binomial regression model. Regression analysis is conducted separately for manufacturing firms by firm size and we use the 2010 Korea Innovation Survey data. Moreover, we explore the spatial structure of product innovation networks across regions using social network analysis. As a result of analysis, networks have a positive effect on product innovative outputs in large- and small-sized firms. In large and small firms, product innovation networks are mainly concentrated in Seoul, Gyeonggi and Gyeongnam, while Jeju and Gangwon are alienated from the network.

The heat wave is already a serious natural disaster that has been selected as a major threat to the world by 2020 at the World Economic Forum. As a result, a amount of public funds have been invested for the purpose of countering the heat wave, but it is not reasonable since it has not been closely reviewed for its effectiveness. In this study, Daegu Metropolitan City was set as a pilot system, and among the various heat wave measures, especially focused on the heat wave vulnerable class support project, we analysed using System Dynamic method how the pattern of occurrence of heat sickness, which can be seen as the effect of the policy, changes as the rate of support for the vulnerable class fluctuates. In addition, in terms of the complex prescription of the policy, we also examined the effect of the mixed prescription for the support policies for the vulnerable groups and eco-friendly policies. As a result of the analysis, strengthening the support for the vulnerable groups was confirmed to reduce the number of patients with thermal diseases, and to increase the GRDP and revitalize the local economy. High synergies are expected when supporting eco-friendly policies such as fossil energy reduction along with supporting the vulnerable groups in the heat wave. It is expected that the results of this study will be utilized as a basis for determining the priority of the heat wave countermeasures, thereby contributing to improving the efficiency of the heat wave countermeasures.
