The 14 cities and guns within Gangwon-do were divided into three regions (urban-rural-integrated type, urban type, and ruralcoastal type), and local voluntary disaster prevention organizations in those regions were surveyed as sample groups. As a result, the urban-rural-integrated type and the urban type were found to be lower than the rural-coastal type in all domains including recognition of disaster crisis, evacuation guidance, preparation of voluntary evacuation, maintenance of disaster prevention system, surveillance & guard, and information delivery. In particular, three types had higher information delivery but considerably lower preparation of voluntary evacuation. As for information delivery, foundations for rapid delivery of disaster information due to establishment and extension of systems for forecasting and warning of local governments were prepared, but as for preparation of voluntary evacuation, it is needed not only to perform consistent training and promotion for preparation for disasters for residents to accurately understand status of disasters but to take measures to secure safe places for evacuation beforehand.

Recently, the aviation leisure business has been legislated, and related industries have become active base with increasing the light sports aircraft within the legislation system. However, in the light sports aircraft safety problem, it is often mentioned that the flight is in violation of the regulations, the lack of safety consciousness of the operator and lack of ability, and the personal operators have a risk of accident of light aircraft such as insufficient safety management and poor maintenance. At present, the maintenance of light sports aircraft is carried out by the A & P mechanic in accordance with the relevant laws and regulations, but it is difficult to say that it is equipped with qualification and expertise. It is not a legal issue to undertake light sports aircraft maintenance work on the regulation system. However, the problem of reliability and appropriateness is constantly being raised because airplanes, light sports aircraft, and ultra-light vehicle are classified and serviced in a legal method. Although legal and institutional frameworks for light sports aircraft are separated, much of it is stipulated in the aviation law provisions. Light sports aircraft maintenance work also follows the current aircraft maintenance system. In the United States, Europe, and Australia where General Aviation developed, legal and institutional devices related to maintenance of light aircraft were introduced, and specialized maintenance tasks are covered in the light aircraft mechanics system. As a result of analysis of domestic and foreign laws and regulations, it is necessary to introduce the qualification system for maintenance of light aircraft. In advanced aviation countries such as the United States, Europe, and Australia, a light sports aircraft repairman system is installed to perform safety management. This is to cope with changes in the operating environment of the new light sports aircraft. This study does not suggest the need for a light aircraft repairman system. From the viewpoint of the legal system, the examination of the relevant laws and regulations revealed that the supplementary part of the system is necessary. It is also require that the necessity of introduction is raised in comparison with overseas cases. Based on these results, it is necessary to introduce the system into the light aircraft repairman system, and suggestions for how to improve it are suggested.

Along with green growth era in the 21st century and with the increasing economic, social, and cultural stabilization, people expect absolute freedom from the drought and flood and long for ecological exchange in the waterfront as a part of the living base at the same time. In order to match the changes in social demand, the focus on the river management policy urgently requires a comprehensive river management that considers the nature's environmental and ecological aspects as well as a new disaster prevention approach that grows out of existing simple flood prevention. Therefore, this thesis provides feasible solutions by suggesting the following findings to maintain and manage rivers to be harmonized with the natural environment considering disaster prevention aspects. It is necessary to change the river management policy and integrated river basin management, to control the river management lead by the central government and to promote close-to-nature river management approach for environmentally sound and sustainable development.

The development of weapon systems (or components) is hindered by the number of tests due to the limited development period and cost, which reduces the scale of accumulated data related to failures. Nevertheless, because a large amount of failure data and maintenance details during the operational period are managed by computerized data, the cause of failure of weapon systems (or components) can be analyzed using the data. On the other hand, analyzing the failure and maintenance details of various weapon systems is difficult because of the variation among groups and companies, and details of the cause of failure are described as unstructured text data. Fortunately, the recent developments of big data processing technology, machine learning algorithm, and improved HW computation ability have supported major research into various methods for processing the above unstructured data. In this paper, unstructured data related to the failure / maintenance of defense weapon systems (or components) is presented by applying doc2vec, a machine learning technique, to analyze the failure cases.

Flood discharge capacity in a dam downstream reach has been decreased after dam construction because of the river cross section reduction impacted by farm lands, sand-bars and parking lots, etc. in river flood plains. Those obstacles being in the river inside areas have caused negative influences to the dam operation policy. Therefore, the dam downstream river improvement work associated with the dam operation improvement plan is under construction for removing reduction factors on the dam effective storage, assuring flood safety in the dam downstream river and incrementing dam operation benefits. But the project has issued some problems such as project feasibility, economic evaluation, cost allocation and benefit share, etc. Since a dam enterpriser has not committed such kind of project before, it is necessary to set up an objective analysis process and a quantitative financial valuation. This study examines the measurable economic benefits and the cost allocation of the project for the fairness between benefit owners (central government and water electricity enterprisers). As a result, the total economic benefit from 3 dams (Imha, Daechung and Youngdam Dam) accounts for 14.41 Billion Won/year. The financial valuation of K-water as a project enterpriser is approximately estimated at 40% of the total value and the government is 60%.
