This study develops textile designs and cultural fashion products with the image of 'Youngguchunhwa', which means the beautiful spring flowers of Jeju. Historical literature was reviewed to emphasize the authenticity of Halla Mountain and Youngguchunhwa. Consumers' responses to Halla Mountain, Baengnokdam, and Royal Azalea related to Youngguchunhwa were evaluated along with photos of Halla Mountain and Youngguchunhwa images upload on Internet during the last 2 years. The results of consumer survey and photo analysis confirmed the consumers' high preference and high association with the image of Jeju. The full-blown Royal Azaleas in the Seonjakjiwat field of Halla Mountain were used as motifs for the development of Jeju cultural products as a representative landscape showing the beautiful spring of Jeju. Six types of textile designs were developed by the repeated arrangement of the basic patterns of Halla Mountain, Baengnokdam, and Royal Azalea. Ladies' apparels products, children's wear, bags and cushions were made using oxford cotton fabrics printed with the textile designs. We suggest how pattern designs of the Youngguchunhwa image could be applicable and used for the development of other kinds of Jeju tourism souvenirs.

Though numerous drilling has been performed in Jeju Island for development of ground water, the wells are mostly located along the coast lines or at low altitude area, and can hardly be found on the mid-mountain area. Two-dimensional magnetotelluric (MT) surveys have been carried out to cover the lack of geological Informal ion on the mid-mountain area and to figure out any possible structures or evidences for deep geothermal energy remained. Two-dimensional (2-D) inversion of MT data for four survey lines surrounding the Halla mountain show a thick layer having around 10 ohm-m in the depth of a few hundred meters throughout the survey area, which can be considered as the unconsol idated sedimentary layer. And they also show a conductive anomaly extending to more than 2km depth at the central part of each survey lines, which can possibly be related with old volcanic activities during the formation of Halla Mt.. Further seological/geophysical investigations should be followed.

The objective of this study was to investigate the possibility of seeding methods for quarry rehabilitation. To achieve the objective, the experiment was designed for rehabilitation of quarry with seed mixing types (woody type and herbaceous type) and forest topsoil. Seeds and seeding materials were applied to the quarry slope using hydroseeding measures. The study was conducted in limestone quarry (Lafarge Halla Cement Inc.) near Baekdu Daegan Mountain System at Okke, Kanwon-do. The experimental seedbed was set in 2007 and field investigation was carried out from 2007 to 2010. As the result of experiment, it was found that the early-phase pattern for surveyed species to establish was affected by the soil mixture types. The mixture type of herbaceous seeds resulted in the higher plant coverage than the woody seeds. The application of forest topsoil showed a potential increase the plant diversity, but it was affected by mixing seeds. Naturally-emerged species as Alnus hirsuta, Quercus mongolica will be useful for rehabilitation at the quarry and damaged slopes.

Background: The recent, decline in Black-berry Magnolia Vine (Schisandra repanda; BMV) native to Jeju Island, Korea, has raised concerns about the causes of this decline. We investigated the native environment of S. repanda and evaluated its propagation through cuttings to provide preliminary data for its restoration in Jeju Island. Methods and Results: The native environment of the BMV in the Hallasan National Park was surveyed and the climatic variables (temperature and humidity) were analyzed. The effects of the sex of the donor plant (male/female) type of cutting (softwood/hardwood), and treatment with a plant growth regulator (indole-3-butylic acid/rootone) on the rooting of BMV were investigated. Additinallly, the rooting rate, root count, and root length, as well as temperature and humidity were measured in the vinyl moist chambers. BMV was observed in 63 plants distributed from 567 m to 1,364 m above sea level of the Hallasan National Park. In the cutting experiment, the rooting rate was 71.9%, and it was higer in female plants (75.0%) than in male plants (68.8%). Conclusions: The mass propagation of BMV through cuttings valuable for its restoration as without such safeguard measures, the population could face extinction within a few decades.

This work aims to select the potentially vulnerable plant species against climate change at alpine and subalpine belts of Mts. Sorak, Jiri, and Halla, from central, southern, southern insular high mountains of the Korean Peninsula, respectively. The selection of global warming related vulnerable plants were performed by adapting various criteria, such as flora, endemicity, rarity, floristically specific and valuable species, species composition at mountain summits, horizontal and vertical ranges of individual species, and their distributional pattern in the Korean Peninsula. Line and quadrat field surveys along the major trails from all directions at height above 1,500 meters above sea level of Mts, Sorak, Jiri and Halla were conducted each year during spring, summer, and autumn from 2010 to 2011. Based upon above mentioned eight criteria, high level of climate change related potentially vulnerable arboral plants, such as Rhododendron aureum, Taxus caespitosa, Pinus pumila, Oplopanax elatus, Vaccinium uliginosum, and Thuja koraiensis are noticed from at subalpine belt of Mt. Sorak. Species of Abies koreana, Rhododendron tschonoskii, Oplopanax elatus, Taxus cuspidata, Picea jezoensis, and Juniperus chinensis var. sargentii belong to climate change concerned vulnerable species at subalpine belt of Mt. Jiri. High level of climate change related species vulnerability is found at alpine and subalpine belts of Mt. Halla from Diapensia lapponica var. obovata, Salix blinii, Empetrum nigrum var. japonicum, Vaccinium uliginosum, Juniperus chinensis var. sargentii, Taxus cuspidata, Rhamnus taquetii, Abies koreana, Hugeria japonica, Prunus buergeriana, and Berberis amurensis var. quelpartensis. Countermeasures to save the global warming vulnerable plants in situ are required.
