  • The natural resources of Jeju are recognized as the new regional image of that clean island. Reflecting these trends, this study is initiated to develop a textile design with the motive of persimmon, a natural resource of Jeju, and to apply it to infant's and children's clothes. Its purpose is to highlight the image of persimmon, a traditional dye, as a regional signature for Jeju. Product development procedure included, understanding the use of persimmon for fashion products, analyzing Infants' and Children's designer collections over the last three seasons (focused on 2014S/S, 2015S/S, and 2016S/S), and surveying the Children's Clothes market for persimmon dyeing in Jeju. The conclusion was that, the natural resources of Jeju are highly valuable, and should be applied to textile design and apparel products for children. Utilizing Jeju persimmon was actively studied, but, the market for the Jeju persimmon natural - dyeing products is extremely limited. Moreover, the apparel products for infants and children represent old-fashioned styles, despite their higher prices. Therefore, using the formative characteristics of persimmon for each theme was suggested for development of patterns for textile design. Pattern designs were expressed using textured textile screen-printing, embroidery and $appliqu{\acute{e}}$ for infants' and children's clothes. In this study, a total of 10 items were prepared as apparel products for infants and children. All items were designed considering mix-and-match, potential, with each other or with regular mass-market products. These results are expected to contribute to highlighting the unique image of Jeju and to help promote fashion culture products.

  • This study was conducted to lay the foundation for considering the qualitative aspects of environmental resources by calculating the weight of each environmental resource to calculate the total amount of environmental resources in Jeju. By comparing and analyzing the results of the expert survey conducted in 2011 and the results of the expert survey conducted in 2011 and 2022, changes in experts' perceptions and implications over time were derived. In addition, based on the results of the recent survey, the weight according to the relative importance was calculated to lay the foundation for calculating the total amount of environmental resources in Jeju. The results of this study are expected to provide basic data necessary for the successful institutionalization of the total environmental resource system by providing a scientific basis for the calculation of the total environmental resource. As a result of comparing the survey conducted in 2011 to the survey conducted in 2022 to establish a total environmental resource management plan in Jeju Special Self-Governing Province, there was a difference in the relative importance of the environmental resource category. Although the ranking between categories did not change, it was confirmed that the relative importance of the natural and local resource environment decreased and the relative importance of the living environment field increased significantly. Over time, the importance of plants and wildlife increased, the importance of landscapes and topographic geology decreased, the importance of wetlands and caves increased, and the importance of Gotjawal, natural monuments, and cultural history decreased. In the living environment category, the importance of water pollution increased significantly, and in the humanities and social environment category, the importance of population increased and the importance of industry decreased. It is judged that most changes in item importance are largely influenced by changes in the background of the times and overall perception. It was confirmed that the importance of plants, wildlife, wetlands, and caves with relatively high awareness and the importance of water pollution, which is emerging as a regional problem, have all increased significantly due to structural problems of population age.

  • This study examines the changes in environmental resource perception and residential areas on Jeju Island. This study focuses on Jeju Island, which has prepared a legal framework for the total amount of environmental resources. The study identifies Jeju residents and non-provincial citizens, analyzes the differences between them, and suggests the future direction of the total amount system for environmental resources. This study aims to provide essential data necessary for successfully implementing the assigned environmental resources. This will contribute to sustainable growth and preserving valuable environmental resources in an era where environmental importance is increasing. The findings indicate that both Jeju residents and non-provincial citizens are satisfied with the current environmental resources on the island. However, when comparing past and current environmental resources, Jeju residents generally indicated lower satisfaction over time, whereas non-provincial citizens perceived an improvement over time. While overall satisfaction with the natural and local environment remains high, there is a notable increase in perception regarding the ecological value of plants, wildlife, wetlands, and Gotjawal areas compared to the past. These findings emphasize the importance of incorporating these high-priority components into the total environmental resource system for future consideration.

  • Stonewall in Jeju has been regarded as the one of the most esthetic landscape in rural regions. In addition, they have been played as a useful facility to protect houses or crops from strong winds, but also to indicate the boundary of ownership. In the recent research, stonewall has been appointed as the one of important components in rural landscape. Thus, stonewall in Jeju retains intrinsic and real value by many usages in rural regions. However, in spite of it's value, stonewall has been abandoned without any concerns and political measures. Now stonewall is urgently needed to be dealt by a certain political measure for protection. Therefore, the depth of concerns and systematic management measures for protection should be discussed and made, otherwise the destruction of these natural valuable structures will be continued. In this sense, the purpose of this paper, first of all, is to examine the status of stonewall in jeju. And then, with the result of this examination, political measures and suggestions to protect stonewall are proposed. Several areas such as Sungsan, Sinchon, and so on in Jeju are selected as the sample areas for this study, and examination are carried with a wide range of literature reviews and the GIS technology for data collection and analyses.

  • Jeju island has an area of $1,810km^2$ and is considered the largest island in South Korea. In Jeju Island the average annual precipitation is 1,957mm. About 54% of precipitation is estimated to be lost due to evapo-transpiration and direct runoff, and the remainder is recharged. Historically springs and puddles were the island's primary sources of water. However, after 1970 all sectors, including the urban and industrial sectors depended solely on groundwater as their water resource. As vast amount of water is being recharged the Island has many springs, especially near the coastlines. Historlcally, spring of Jeju Island formed village and make it possible to continue a life. Also it produces many values such as the spring related story, culture, tourism and ecosystems. Especially, the naturally rare phenomenon that about 900 springs appear over the whole area of Jeju Island makes it possible to call it as a natural heritage. As a result of this most springs have either been destroyed or been in the state of neglect. In some cases it has been observed that springs were preserved by nature, however majority of the cases saw springs losing their own nature as a result of abandonment. It was recorded that there were 911 springs in Jeju Island with most of them being distributed along the coast, which consequently increases their susceptibility to seawater intrusion. The objective of this study is therefore to analyze Eco-cultural and Engineering characteristics about springs in the island, highlighting its past utilization and reestablishing its potential as a source of spring.

  • To use mountain ginseng adventitious roots (MGAR), which is superior in functionality compared to ginseng, and to mass produce raw materials as a functional cosmetic material, the antioxidant and cosmeceutical activities of the extracts of MGAR at different ethanol concentrations (0, 20, 40, 60 and 80%) were compared and analyzed. At first, different ethanol concentrations were compared to determine the best solvent for the extraction of phenolic compounds from MGAR. An 80% ethanol extract with 10.07 mg of gallic acid equivalents/g sample and 0.94 mg of quercetin equivalents/g sample was the best solvent in the extraction of phenolic compounds. However, the 60% ethanol extract had the highest antioxidant activity, evident by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, Trolox equivalent antioxidant capacity (35.01 mM Trolox/g sample) and ferric reducing antioxidant power (460.94 mM $FeSO_4/g$ sample). However, the inhibitory activities of the 80% ethanol extract from the MGAR against tyrosinase and elastase were higher than those of the other extracts. The results of this study show that the extract of MGAR can be used as an easily accessible source of natural antioxidant and as a possible cosmetic ingredient in the cosmeceutical industry. However, the components responsible for the antioxidant and cosmeceutical activities of the MGAR extracts are currently unclear. Therefore, it is suggested that further studies should be carried out to isolate and identify the antioxidant and cosmeceutical components in MGAR.
