This study aims to explore regional risk assessment based on the probability of disaster. The analysis also attempts to generate the safety index of regional disaster events, which stochastically follows Poisson distribution. In this article, traffic accidents, natural disasters and fires are chosen as the main disasters of Korea. Multidimensional scaling(MDS) method are used to differentiate the analysis results visually. It can be said from the analysis results that the probability distribution on regional disaster risk has dramatically changed over the past forty years and reflects various aspects of regional safety environments. The results also support that local governments will have to effectively cope with the main disasters in terms of regional-specific risk management.

This paper aims to explore how development collides with safety value pinpointing the dynamic relationship between economic growth and safety value in Australian coastal cities. Also the research attempts to draw some implications from Australian cases with the urban development in coastal cities, which may be applicable to the coastal development in South Korea. When it comes to urban development and safety in Australian coast, risk-based land use zoning, PAR strategy and guidelines for urban development in coastal cities are introduced. The results of case studies also support that the consensus among stakeholders should be built before the application of new regulations and guidelines.

본 연구는 물을 둘러싼 지역사회의 인식을 ‘물문화’로 정의하고, 강원도와 경기도를 대상으로 지역에 따른 문화양식의 차이를 실증분석 하였다. 분석방법은 토픽모델링과 감성분석 등 물문화 관련 뉴스를 살펴보는 미디어 빅데이터 분석 방법론을 적용하였다. 분석결과 강원도는 자연주의자, 경기도는 성장론자의 문화행태가 두드러진 것으로 나타났다. 한편, 공통적으로 재난주의자와 지역주의자 행태들이 나타나지만, 내용적 측면에서 지역에 따라 관심영역이 차이를 보이는 것으로 나타났다. This paper aims to examine the social perception gap between regions in terms of water culture. In this study, regional community’s perception of water would be operationally defined as water culture. Gangwon and Gyeonggi are selected as two regions. Big data-based analysis are employed as a methodology, which provides media analysis based on newspaper database. The results of this study presents that Gangwon holds environment oriented perception (naturalism), while Gyeonggi has growth oriented perception. The study results also show that disaster oriented perception and region oriented perception vary considerably in topics and regions.

This article attempts to examine the social amplification of risk information with the case of Gyeongju earthquake. There have been few researches on risk information using Big Data, even though many articles have dealt with social amplification of risk. This paper employs big-data based analysis as a methodology. The results present that‘aftershock’ is set up as a main keyword of risk amplification according to the keyword networking analysis. It also shows that the most critical issues of risk information is ‘damages’ and ‘government response’. It implies that the increase and amplification of social risk could be attributed to the inadequate government responses.

This article aims to explore path dependency and social amplification of risk in terms of particulate matter air pollution management of governments. Path dependency explains the tendency of a traditional preference to continue even if better alternatives are available. In this paper, it has been offered as an alternative analytical tool for air pollution management policy of levels of government. A key finding of path dependence in air pollution policy of governments is a property of lock-in effects by historical events. Social amplification of risk framework (SARF) is employed as a another analytic tool for a risk communication of particulate matter air pollution policy by governments. It attempt to tackles negative portrayal of air pollution events interacted with psychological, social, institutional, and cultural processes in ways that amplify perceptions of risk. There is now considerable evidence that risk intensification phenomena have occurred in particulate matter air pollution issue for the past decades.

This paper aims to examine whether or not there has been any significant evolution in such presumption of the relationship between industrial revolution and the environmental issues in terms of time trends. It focuses on how the presumed relationship, which is reflected in the newspaper articles, has changed over the last hundred years (1920~2017). The research employs a big data based approach as a methodology to examine the perception on the relationship from media reports. The results show that the concept of industrial revolution has been changed from material into non-material, while the term of economy have been emphasized. It is particularly interesting that the negative aspect of environmental issues such as pollution and contamination have shifted into the positive aspect of that such as technology and change. The results of this research also support that there will be some possibilities of mutual advancement of industry and environment in the future society.

도시화와 재해피해 그리고 경제성장에 관한 지수분해분석

최충익(Choi, Choongik) 대한국토·도시계획학회 2014 國土計劃 Vol.49 No.3

This paper aims to explore the dynamic relationship among urbanization, disaster damages and economic growth. Also the analysis attempts to figure out spatio-temporal patterns of disaster damages in terms of socioeconomic factors: GDP and population. In terms of methodological approach, this study tackles the spatio-temporal characteristics of regional disaster damage through the index decomposition analysis based on I=PAT equations. There have been many studies on the decomposition to quantify the impact of different factors on the change of energy consumption. However, there are hardly any attempts to decompose natural disaster damages, which may be regarded as environmental impacts of IPAT. The outcome and methodology of this article may make a contribution to the deep implications and wide applications in understanding the characteristics of regional disaster damages in developing countries in comparison with developed countries.

포스트 코로나 시대 부동산시장의 전망과 과제

본 논문은 코로나19가 부동산 시장에 미친 영향과 포스트 코로나 시대 부동산 시장의 변화와 대응방안에 대한 시사점을 도출하고 있다. 본 연구는 코로나19 팬데믹이 부동산 시장에 큰 영향을 미쳤으며, 소비자 선호도, 행동, 경제적 요인에 변화를 일으켜 주거용, 상업용, 소매용 부동산을 포함한 다양한 부문에 영향을 미쳤음에 착안한다. 연구 결과, 부동산 시장이 팬데믹의 영향에 따라 도전과 기회가 발생하는 새로운 현실에 적응하고 있음을 확인할 수 있었다. 주거용 부동산 시장은 주택 구매자들이 공간, 프라이버시, 원격 근무와 온라인 교육을 수용할 수 있는 기능을 우선시하면서 교외 및 외곽 지역으로 이동하고 있었다. 상업용 및 소매용 부동산 시장은 기업들이 원격 근무와 소비자 행동의 변화에 적응하면서 어려움을 겪는 것으로 나타났다. 본 연구결과는 전 세계 포스트 코로나 시대부동산 시장이 소비자와 기업 모두의 변화하는 요구를 충족하기 위해 계속 진화해야 함을 시사한다. This article aims to explore the impact of COVID-19 on the real estate market and the changes necessary to navigate the post-pandemic world. The COVID-19 pandemic has significantly impacted the real estate market, causing changes in consumer preferences, behaviors, and economic factors that have affected various sectors, including residential, commercial, and retail properties. As a result, the industry has had to adapt to a new reality, with challenges and opportunities arising in response to the pandemic's effects. The residential real estate market has seen a shift towards suburban and rural areas, with homebuyers prioritizing space, privacy, and features that accommodate remote work and virtual schooling. Meanwhile, commercial and retail properties have faced challenges as businesses adapt to remote work and changes in consumer behavior. This paper supports that as the world transitions into a post-pandemic era, the real estate industry must continue to evolve to meet the changing needs of consumers and businesses alike.
