The purpose of this study was to obtain information about the type of drones suitable for the management of entrants and entrants of islands in the marine national park. The research sites were 25 islands in the Hallyeohaesang National Park. The target islands were divided into three zones, and were investigated with different types of drones. The survey period was from October to November, 2019. As a result of the operation of drone airframe, drone with fixed wings was found to be favorable for the management of marine parks in medium and long distances compared to other types, but stopping flights for broadcasting was found to be unsuitable. Drone with rotational wings was found to be suitable for image acquisition and broadcasting through close flight. However, it was deemed suitable for short and medium distance flights because of the fast battery consumption. In the case of helicopter rotorcraft drone, image acquisition and broadcasting were possible, but noise and vibration caused by propellers were disadvantageous. The number of entrants to the islands totaled 410 and the main act was fishing. The proportion of entrants to the islands in Area A was higher than that of other areas, and thus it was deemed more necessary to manage the area. Broadcasting was found to have had a positive effect on the management of fishers.

This study evaluated the efficacy of information and self-interpretive media that provide information on park environment using self-administered visitor survey to the Dadohaehaesang National Park, Korea. Excluding missing and unreliable responses, 205 valid responses were used for the analysis. Socioeconomic status and visiting behavior of the visitors to the Dadohaehaesang National Park were similar to those to other Korean national parks. Results showed that, of the self-interpretive media, 'Information board of park use and resources' were most frequently used (87.7%), followed by 'Interpretive label of woody plant,' and 'Bulletin boards for information and enlightenment.' 'Guided interpretation' was used less than 40% of the visitors. Visitors also highly rated the importance of the media (higher than 4.0 on average out of 5 point Liker scale question). The average performance rate was 3.82, suggesting that visitors were satisfied on the self-interpretive media. Visitors responded that 'Information board of park use and resources' and 'Bulletin boards for information and enlightenment' were not useful and, therefore, should be amended and managed to improve the self-interpretability of the media.

A total of 10 islands (Kumodo and Komundo in Yeosu City; Oinarodo in Goheung County; Chongsando, Soando, and Pogildo in Wando County; Chodo in Jindo County; Uido, Huksando, and Hongdo in Shinan County) were surveyed to confirm distribution of naturalized plants from June 2006 to December 2008. A total of 100 naturalized plants taxa from 25 families were recorded. The highest number of naturalized plant species (82 taxa) was recorded on Oinarodo, while the lowest number was recorded on Hongdo (42 taxa) and on Uido (34 taxa). A total of 26 naturalized species taxa (such as Dactylis glomerata, Lolium perenne, Bromus unioloides, Rumex obtusifolius, Chenopodium album, Phytolacca americana, Barbarea vulgaris, Lepidium apetalum, Robinia pseudo-acacia, Trifolium repens, Erigeron annuus, Erigeron canadensis, Senecio vulgaris, Xanthium strumarium) was recorded in all study areas. Distribution of naturalized plants were categorized into 7 habitat types based on ecological traits: afforested land, beach, port, and vacant land, road boundary, road cut and slope area, waste arable land, landfill area, and wetland. Systematic management is required to conserve unique landscape, species diversity, vegetation and ecosystem of Dadohae National Park. In order to manage the naturalized plants in Dadohae National Park, basic surveys are most needed to understand distribution and dispersal of naturalized plants communities based on ecological features of each habitat type.

The purpose of this study was to evaluate the area adjustment criteria and methods of the feasibility study of national park plans by applying them to Hallyeohaesang National Park. As a result of the ecological-based assessment used to identify the adjustment target areas, the ecological-based assessment Grades I and II that can be considered for inclusion were analyzed as 10.0% and 40.4%, respectively. Grade V, which can be considered for release, was 9.9%. As a result of the inclusion and release suitability assessment, the area subject to inclusion was 35.150 km² (3.669 km² on land and 31.481 km² at sea), and the area subject to release was 0.071 km² on land. When local governments and residents request the release of a park area for public interest or convenience, the release can be considered as long as the total area does not change, which is called a mutual exchange. The release area determined by mutual exchange was 10.386 km². It was 146 times the area determined by the suitability assessment for release. Matching the areas released by the mutual exchange with the ecological-based assessment, 70.6% (7.321 km²) was in Grades I and II, which can never be released. As a result, it was determined that the area adjustment of the feasibility study of Hallyeohaesang National Park was based on a very limited application of the results of the ecological-based assessment or the release suitability assessment. Also, mutual exchange was the key to area adjustment of the feasibility studies of national parks.

The objective of this study is to develop quantitative criteria for setting reasonable standards and regulations for building heights in collective facility districts inside national parks or those connected to their borders. Heights of all building sin collective facility districts were simulated in order to determine heights of ridge lines of sight passing the upper parts of buildings from a main view point. Where a facility's zone is located at the inside or boundary of inland mountainous national parks, and there are coastal type national parks with mountains in the background, the study recommended assigning the maximum allowable height of a building as 8.82m if national park authorities intend to preserve the ridges at three-tenths the height of a mountain. It amounts to 3 or 3.5 stories when it is converted into the number of floors. It is desirable to apply this standard to accommodations like a hotel except lodge or cottage as the maximum allowable height of a building. Nevertheless, when there aren't back mountainous areas among coastal-type national parks, there is a need for applying a separate standard. If an equal and uniform standard is applied to all collective facility districts, it becomes difficult to address local differences when managing landscape. There must be flexibility when applying a standard, depending on variables such as location of view points, differences in the methods of selection of view points, and differences in view angles, etc. Thus, there is a need for different landscape management strategies that address the unique natural environment of different zones.
