Natural disaster has been hard to prevent the occurrence of itself, thus in order to reduce the economic damages and loss casualties, it is important to be prepared in cases that the disasters should occur in advance. Interest of the related project to prevent various natural disasters has been grown along with an investment in Korea. Along with this movement, when investments related to natural disaster prevention projects were built on, the post evaluation that can verify the ripple effects of those investments on the community should be emerging as an essential task. For evaluating the effects of public investment projects such as natural disaster prevention projects in this study, the related researches would continue through qualitative analyses, for example, cost-benefit analysis. Even the qualitative analysis alone cannot fully explain the effects of those projects, the diverse methods of analyzing and evaluating those effects might not have been presented in those fields. For the post evaluation of natural disaster prevention projects through the qualitative analysis, this study derived subjects that had effects on the post evaluation of natural disaster prevention projects. Also, employing the structural equation modeling (SEM), the causation between post evaluation subjects and the effects of projects were quantitatively analyzed, and the weighting factors of evaluation items were calculated respectively. Based on these results, post evaluation index formula was proposed for the natural disaster prevention projects in Korea.

The purpose of this study is to suggest some effective ways to implement the regeneration projects for the zones vulnerable to natural disasters which have been delayed due to shortage of the financial resources, and thereby complete the disaster prevention projects as early as possible and thus secure the financial resources for the projects continuously. For this purpose, the researcher reviewed the statutory grounds and designation procedures or the zones vulnerable to natural disasters, and thereupon, examined and analyzed the regeneration projects being implemented in Gyeonggi-do in view of contents by zone, history of damages, annual investment plans and financial resources for investments. In addition, the researcher examined the criteria for reserve of the disaster management fund and its uses and investigated the fund sources and expenditures and thereby, addressed the problems of the statutory reserve and suggested their solutions. All in all, the researcher suggested that the disaster management fund should be invested in regeneration projects for the zones vulnerable to natural disasters in order to remove the disaster risks earlier and that the uses of the fund should be adequately deregulated with a reserve fund ceiling system to secure the financial resources for the disaster prevention projects continuously.

Due to natural disasters such as heavy rain that occurred in the metropolitan area in August 2022, human casualties and property damage are increasing. Accordingly, the government is making efforts to respond to natural disasters, but due to the absence of related standards and standardized standards, problems such as increased construction costs and deterioration in construction quality for disaster prevention facility maintenance projects are occurring. Accordingly, a rough construction cost estimation module was developed and applied to 25 new pumping stations in Korea. As a result of the analysis, the accuracy of the rough construction cost derived through the module recorded 70% of the detailed design cost, which is 4% higher than the previously used rough construction cost accuracy of 66% by the Ministry of Environment. Accordingly, it is expected that the efficiency of the disaster prevention project can be increased if the developed module is used to calculate the rough construction cost for storm and flood disaster prevention in the future.

Disasters that occur most frequently in rural areas are drought, flood, damages from wind and cold weather. In order to overcome the damage caused by natural disasters, various projects related to safety and disaster prevention. However, Government-centered disaster recovery operating system showed difficulties to utilize the natural scenery and ecological environment of rural villages. So the participation of the residents is necessary. Therefore, this study aims to find a more effective disaster recovery direction by suggesting the application method, Inhabitant-friendly improving a village environment contents in Rural Disaster Villages, for continuous disaster management. The research methods were literature analysis, interviews, and expert discussion. As a result, it was found that the rural disaster village environmental improvement facilities, inhabitant-friendly recovery system, and inhabitant-friendly village environment contents and suggests a application method of inhabitant-friendly village environment contents. The research will be used as basic data when preparing a guide for improving the environment for residents in rural villages.

The rapid increase in the number of climate disasters combined with the scale of change and the diversification of natural disasters require a radical solution. In particular, the urban space is more complex, therefore we need to establish measures for disaster response and how to react to damaged infrastructure based on the phenomenon of an increase in the urban population and the impermeable layer being extended. The social problems related to the economic burden of land purchase and the securing of a disaster prevention system can be solved simultaneously by introducing the park system for disaster reduction into the public land of the green space in the city. The local government has recently adapted diverse systems of disaster mitigation and carried out pioneer projects according to the guidelines for the construction of the urban park for disaster prevention published by the Ministry of Land, Infrastructure and Transport. The purpose of this study is to propose a composition model for neighborhood parks to prevent disaster through urban green spaces which has the functions of water management and biotope conservation. The result of this study will contribute to utilize the climate change adaptation model for living area neighborhood parks in the existing urban structure.

As the procedure of the close examination of disaster impact at the initial stage of the beginning of development plans, the newly extablished Pre Disaster Impact Assessment Review Deliberation (PDIARD) system which have been introduced through the revision of the Natural Disaster Countermeasure Act-revised at August, 2005 is enforced for the purpose of the disaster prevention which caused during a development projects. From that time down to this day, the PDIARD system have been reviewed about 6,000 cases totally. However, the current the PDIARD system at the uppermost limit in the aspect of every Acts and operational problems is in need of sustaining supplementation at the present situation. To cope with this operational remedy related to the PDIARD system, this study deals in 3 major concerns. First, it is required to fix a criterion in detail because of a wide range of the subject plans of deliberation. Second, there is some ambiguity according to the area or length of the subjected administrative and development plans. So it should be excepted of the targeted plans which has few probability in disaster potential or vulnerability. Finally, the subjected plans need to be added as to the continuous urbanization and industrialization and the enactment or revision of the Acts related. This study focuses on the investigation and analysis to find out the improvement way about the main problem pending of the PDIARD system, consequently suggests a effective remedy and new categories, including future directions and detailed plans for operation.

As a future clean substitute energy, the Gas hydrate development projects are world widely carried out to prepare the shortage of petroleum and natural gas resources. The OIIP of gas hydrate is estimated approximately 10 Trillion LNG equivalent ton and it reaches almost the amount of 5 thousand years use for the world people. To develop the commercial production technology, several research projects like Malik and Alaska project have been carried by several advanced countries and teams, but nobody have succeeded it yet due to the technical problems and the high risks. The technologies developed up to now for the hydrate production are categorized to four methods, such as depressurization method, thermal recovery method, inhibitor injection method and replacement method. As these methods are highly related to the costs and the environmental problems, many other researches including the safety, environment and disaster prevention are actively fulfilled as well.

Recently, a great number of natural disasters have more frequently happened than the past. The National Emergency Management Agency of Korea has made preparation for the integrated management system of steep slope lands. There is information based on the steep slope inspection sheets and the underground spatial information related to the prevention against steep slope disasters. Nevertheless, building a complete DB System to prevent the hazards and secure the safeties should be urgently dealt with. It is mainly because the information of the National Disaster Management System is restricted to the text-based brief data. Therefore, the purpose of this study is to suggest the method as to building steep slope DB system for disaster prevention and maximizing the availabilities. This study shows the way of building a web-based DB system having its root in the steep slope inspection sheets. The method of establishing the ideal DB system that has liaisons between the Ministry of Land, Infrastructure and Transport and the National Emergency Management Agency is discussed in this study. Furthermore the optimization of DB utilization will assist the various integrated steep slope management systems based on U-IT which are ongoing projects.

Natural stream disasters due to a localized torrential and flash flood has occurring in a small stream especially un-implemented small stream. The survey results during ten years from 2001 to 2010 show that the small stream implementation projects (SSIPs) expenses is increasing with the damages is generally decreasing with variableness in which SSIPs is contributing to disaster prevention in a small stream. This study develop guideline for the selection of SSIPs to support high risk stream at first and save the small streams located on the mountainous area, prevention area and agricultural area which streams have no implementation effects. Developed sub items in guideline are evaluated by stream data collected from 212 small streams where it is proved that sub distance of each item are well arranged by normal distribution. This SSIPs is useful for selecting high risk small stream at first to maximize disaster risk reduction with minimum SSIPs expenses. Also, this SSIPs is used for leading to save small stream on the upstream to minimize flood damages on the down stream with selection a SSIP purchasing agricultural land for preparing flood plane.
