The national parks of South Korea take up an area of 6,726 ㎢, which accounts for 6.7% of the national land. They are national conservation areas with their area made up of 59.1% of land (3,972.6 ㎢) and 40.9% of seawaters (2,753.7 ㎢). And in 2019, the national parks are classified by type into 17 mountainous, 4 maritime or coastal, and 1 historical site. Here, the maritime or coastal nation parks are lately spotlighted as landmarks in maritime tourism. However, the area of the maritime or coastal national parks is continuously dwindling due to conflicts between the residents in the parks and Korea national park service, the continued pressure with respect to the regional tourism development and private investments, and the abolition of parks in relation to allegedly breached private properties. This study identifies the issues with the operation and management of national parks as caused by the abolition of parks and the reduction of areas, and goes from there to do research with the aim of suggesting an institutionalized improvement plan with a view to more useful operation and management of the maritime or coastal national parks. As a result, the natural resources in the sea and on land should be surveyed again to establish the standard for use-specific zoning and reorganize the park areas in adjusting the national park areas. Second, the use-specific districts need to be reviewed for their reorganization that meets the designation requirements by focusing on the characteristics of the different national parks with a view to ensuring reasonable natural conservation in the maritime or coastal national parks. Third, various support facilities for residents such as public path, lodgings, and rentals need to be created to reduce the conflicts between Korea national park service and those who live in the parks.

In order to preserve beautiful coastal areas landscapes of Jeju Island's the landscape resource, Jeju Special Self-Governing Province is dedicated to protecting the landscape through legal regulations and deliberations. However, the Coastal Landscape of Jeju Island was continuously damaged by due to increased tourist and high development pressure. Based on buildings along the Coastal Road in Aeowal of Jeju Island, this study focused on Management Status of Coastal Areas Landscapes through the Analysis of Building Landscape Elements. As a result, 1) It was effective to limit the use and scale of buildings through legal regulations such as Use zoning. 2) The result of analysis on the physical landscape elements of buildings showed some of the them have the damage values despite passing the review of Architecture Committee. Therefore Landscape Policies required institutional maintenance. 3) As physical landscape Elements of buildings is a minimum quantitation criterion of not less than 1.5 for D/H, or less than a factor of $27^{\circ}$ for angle of elevation and not less than 7.8m for elevation blockage ratio was presented as a criterion for preventing damage to the minimum Coastal Landscape.

Earthquake-induced disasters are often more severe in locations with soft soils than firm soils or rocks due to differences in ground motion amplification. On a regional scale, such differences can be estimated by spatially predicting subsurface soil thickness over the entire target area. In general, soil deposits are generally deeper in coastal or riverside areas than in inland regions. In this study, a coastal metropolitan area, Incheon, was selected to assess site effects and provide information on seismic hazards. Spatial prediction of geotechnical layers was performed for the entire study area within the GIS framework. Approximately 7,000 existing borehole drilling data in the Incheon area were gathered and archived into the GIS Database (DB). In addition, surface geotechnical data were acquired from a walkover survey. Based on the built geotechnical DB, spatial zoning maps of site-specific seismic response parameters were created and presented for use in a regional seismic strategy. Site response parameters were performed to determine site coefficients for seismic design over the entire target area and compared with each other. Site classifications and subsequent seismic zoning were assigned based on site coefficients. From this seismic zonation case study in Incheon, we verified that geotechnical GIS-DB can create spatial zoning maps of site-specific seismic response parameters that are useful for seismic hazard mitigation particularly in coastal metropolitan areas.

The purpose of this study is to propose new systems for improvement of coastal landscape management in Busan area. The coastal landscape management systems in Busan are divided into urban planning sector, coastal management sector and environmental preservation sector without any comprehensive lay or integrated management system. These findings indicate that the coastal landscape is in need of integrated management in the form of coastal management rather than urban planning because coastal landscape os different from urban landscape by nature. The coastal landcape management ordinance which is based on the Coastal Management Ant should be established and the special zoning system for costal landscape management is to be set up under this ordinance. Then the comprehensive landscape plan for Busan coastal area and the design guidelines for each zone are mandatory. Also Busan city government and the district office must have a responsible department, experts and coastal landscape review committees.

In coastal residential communities, especially along the coastline, flooding is a frequent natural hazard that impacts the area. To reduce the adverse effects of flooding, it is recommended to elevate coastal buildings to a certain safe level. However, post storm damage assessment has revealed severe damages sustained by elevated buildings' components such as roofs, walls, and floors. By elevating a structure and creating air gap underneath the floor, the wind velocity increases and the aerodynamics change. This results in varying wind loading and pressure distribution that are different from their slab on grade counterparts. To fill the current knowledge gap, a large-scale aerodynamic wind testing was conducted at the Wall of Wind experimental facility to evaluate the wind pressure distribution over the surfaces of a low-rise gable roof single-story elevated house. The study considered three different stilt heights. This paper presents the observed changes in local and area averaged peak pressure coefficients for the building surfaces of the studied cases. The aerodynamics of the elevated structures are explained. Comparisons are done with ASCE 7-16 and AS/NZS 1170.2 wind loading standards. For the floor surface, the study suggests a wind pressure zoning and pressure coefficients for each stilt height.

Prognostic characteristics of hypothetical tsunamis in the East Sea are further discussed based on numerical simulations using linear long wave theory than the last paper(Choi et al). As for choice of source zones, we used 28 cases based on fault parameters of hypothetical earthquakes and 76 cases based on simple initial surface shapes of tsunamigenic earthquakes selected by the seismic gap theory. As a result, the wave heights along the whole coastline adjacent to the East See of tsunamis due to these hypothetical earthquake are presented. Analyses also lead us to conclude that the selection of geographical zones with low risk of tsunamis can be used as a tool for coastal disaster mitigation planning.
