This study is a case study that applied 'UNDRR's Urban Disaster Resilience Scorecard', an evaluation tool necessary for Incheon Metropolitan City to be certified as an international safe city. I would like to present an example that the results derived from this scorecard contributed to the Incheon Metropolitan City Disaster Reduction Plan. Of course, the Disaster Resilience Scorecard can't provide a way to improve the resilience of every disaster facing the city. However, it is to find the weakness of the resilience that the city faces, and to propose a solution to reduce the city's disaster risk. This is to help practitioners to recognize the disaster risks that Incheon Metropolitan City faces. In addition, the solution recommended by UNDRR was suggested to provide resilience in areas vulnerable to disasters. It was confirmed that this process can contribute to improving the disaster resilience of Incheon Metropolitan City. UNDRR has been spreading 'Climate Change, Disaster-resistant City Creation Campaign', aka MCR (Making Cities Resilient) Campaign, to cities all over the world since 2010 to reduce global cities' disasters. By applying the disaster relief guidelines adopted by UNDRR, governments, local governments, and neighboring cities are encouraged to collaborate. As a result of this study, Incheon Metropolitan city's UN Urban Resilience Scorecard was evaluated as a strong resilience field by obtaining scores of 4 or more (4.3~5.0) in 5 of 10 essentials; 1. Prepare organization for disaster resilience and prepare for implementation, 4. Strong resilience Urban development and design pursuit, 5. Preservation of natural cushions to enhance the protection provided by natural ecosystems, 9. Ensure effective disaster preparedness and response, 10. Rapid restoration and better reconstruction. On the other hand, in the other five fields, scores of less than 4 (3.20~3.85) were obtained and evaluated as weak resilience field; 2. Analyze, understand and utilize current and future risk scenarios, 3. Strengthen financial capacity for resilience, 6. Strengthen institutional capacity for resilience, 7. Understanding and strengthening social competence for resilience, 8. Strengthen resilience of infrastructure. In addition, through this study, the risk factors faced by Incheon Metropolitan City could be identified by priority, resilience improvement measures to minimize disaster risks, urban safety-based urban development plans, available disaster reduction resources, and integrated disasters. Measures were prepared.

This study investigated the impact of abandoned channel restoration on fish habitat using the physical habitat simulation. The study area is a 1.2 km long reach of the Cheongmi-cheon stream. In the study area, the restoration of the abandoned channel was carried out from July 2012 to December 2105. Physical habitat simulations were carried out for both cases before and after the restoration. The River2D model and habitat suitability curve were used for hydraulic and habitat simulations, respectively. Zacco platypus, which is a dominant fish species in the study area, was selected as target fish for the physical habitat simulation. Hydraulic simulations were carried out before and after restoration for various discharges. Then, composite suitability index and weighted usable area were calculated before and after restoration and changes in the physical habitat of Zacco platypus were discussed. Simulation results indicated that the abandoned channel restoration is effective in creating fish habitat and mitigating the degradation of fish habitat from the high flow condition.

Today, computer graphics have moved into spotlight within many related fields. The use of computer graphics in many fields as well as in design is now universalized. More than ever, those fields which utilize virtual reality are being vigorously researched and are rapidly progressing. Many advanced countries are obtaining positive results, allowing the world to learn about their culture and history by using virtual reality techniques for the restoration of cultural property. Above all, the West has utilized the diversity of the CAVE system which could best express the artificial system among virtual reality systems. However, in Korea this technology remains in its early stages of development. Moreover, the field, digital restoration of cultural property, which will be discussed in this study, hasn't yet been explored. Accordingly, this study presents the way of digitally restoring cultural property based on the CAVE through the empirical research and suggests the significance and possibility of digitally restoring cultural properly in the CAVE system. For them, this study processes the digitally restoring of Pulguksa Temple and Sokkuram and refers to the limitation and the future study following the investigation of CAVE and the introduction of applicable examples in abroad.

Nowadays, the progress of high technology in modern society provides humankind with the opportunity to obtain diverse information easily and quickly. Among those rapidly progressing fields of high technology, digital media field has the ability to substitute for the multimedia information society by being applied to many related fields and daily life. Specifically, the concern and enthusiasm for the restoration of cultural property has risen. So, effective methods are required to decide on the preservation, restoration and academic value of cultural property. Among these, image processing technology using computers has been introduced. The restoration of cultural property using this technique has been studied vigorously in many advanced countries because this would allow us to restore damaged parts without destroying the original asset. However, in Korea, though we have numerous examples of cultural property with recorded history, research related to the items has scarcely been conducted. Accordingly, this study focuses on the investigation of virtual reality and the techniques applicable to restoring cultural property in addition to suggesting the significance and possibility of digitally restoring cultural property following the introduction of applicable examples both domestically and abroad.

River works for water utilization have substantially altered the natural flow regime, and it has resulted in deformation of healthy river ecosystems. In Korea, river restoration projects have conducted actively since 1990's. Major purposes of the river restoration are the rehabilitation of modified river channel, improvement of water quality, and creation of aquatic habitats as well as recreational spaces using natural material for river work. However, there have been little interests about the restoration of flow regime which influences to most aspects of river ecosystems. The restoration of natural flow regime has received much attention in preservation of aquatic ecosystems. It should be needed to explore the relationship between flow regime and river ecosystems, and the restoring flow regime is essential. This paper introduce the concept of environmental flow through the interrelation between flow regime and river ecosystem. It provides rolls of flow regime and addresses the method of establishing target flow regime using the RVA(Range of Variability Approach) that suggested by Richter et al.(1997) through analysis of altered flow pattern case of Han river basin.

The cadastral boundary points which cadastral surveyor presented on the ground by conducting cadastral surveying represents the limits of land ownership and give binding force and determination power. However the land disputes have increased these days mainly due to cadastral registration errors, surveying errors and land owners recognition error. In these cases, the cadastral survey interests try to find solution by either a administrative procedures by appealing civil complaint or border determination litigation through court. The neighboring residents and related organization have difficulties in resolving the civil complaints. In this study cadastral surveying and cadastral boundary determination process has been reviewed and the results of cadastral surveying screening by Central Cadastre Committee from 2016 to 2021 have been classified. The outcomes of this research will be used for cadastral surveying and contribute for reducing land disputes and improve reliablity of cadastral surveying.
