Bangseonmun(訪仙門) is the attractive spots where Shinseon(神仙: Taoist hermit) ideas that makes Mt. Younju(瀛洲山) or the current Mt. Halla mystique has still remained and situated at Hancheon(漢川) Valley. Bangseonmun, which is known as 'Landscape Setting Here($L_{SH}$)' of Youngguchunhwa(瀛丘春花), which is one of ten famous spots in Youngjusipkyung(瀛洲十景), and Deulreonggui refer to 'the gate to the place where Shinseon is living.' It is described as the path to Mt. Youngju for Shinseon and the boundary between the mundane world and the world beyond the mundane. The old scholars at Mt. Halla entered the gate and met Shinseon, carving the word or picture of Bangseonmun, Whanseonmun, Wuseondae or Deungyounggu so as to structure the enchanting image on Bangseonmun. It is the poetic expression of the taste for the arts, breaking from the troublesome mundane world and riding the white deer to become the Shinseon, the desire for the ideal world in Taoism, and the identity of four famous scenic spots of Bangseonmun. Besides its enchanting meaning and the locational value of Bangseonmun, geological features of the valley and river and ecological value prove its unique value as a natural scenic beauty. Not to mention the locational identity and enchanting meaning of the poets carved in Meeaegak of Bangseonmun and the scenic view of 'Youngguchunhwa' as the subject of 10 famous scenes of Youngju, it is the place for communing with nature with the natural beauty of Bangseonmun Valley. As the cultural place for being together with Jeju people, it simultaneously shows the typical model as a scenic spot in our living. Viewing the scenic value and standard from the aspect of the Cultural Properties Protection Law, Bangseonmun Valley in Jeju must be the typical place and space that meet the requirements to become scenic sites.

Hiking trails in Mt Jiri, and Mt Halla, National Park have been examined in terms of their degrading factors. The trails are deteriorated by natural erosion processes as well as human trampling. Trail deterioration is classified into tread lowering, sidewall retreat, path widening and divergence based upon a place where erosional processes occur. Tread lowering and sidewall retreat is generally produced by natural erosion factors, whereas path widening and divergence is generated by human trampling. Rainwash is the most contributing process to tread lowering. By contrast, several processes such as rainwash, needle ice action, deflation, tree falling and animal activity play a major role in sidewall retreat according to physical conditions of a hiking trail. Path widening and divergence could be classified by a factor producing human trampling. There are lots of cases related to rainwash such as the tree root, gravel, and bedrock, exposed by a surface flow lowering a tread and the riser produced by tread scouring. A puddle of rainwater on a flat tread and a fallen tree of Abies koreana in a forest region are also major factors to cause path widening and divergence. A paved tread with stones encourages a hiker to walk out of a trail. Taking a shortcut also results in path widening and divergence without a factor giving a hiker inconvenience on a trail.

The god of water, Baltara (Bhadra: in the northern part of India), Tammola Around 563-483, he came to Tamra with 900 Arhats (BC483-AD1105, during the reign of King Sukjong of Goryeo, the kingdom of Tamra became Hangun-hyeon in Goryeo). It is the spread of Buddhism through the world's most sacred water (Heiligkeit, one of the four elements water, fire, air, and earth) and the world's largest Arhat The reverse of Halla, appendix: to find the stone statue of Buddha at Seogo Temple in Jeonju, Hwangbangsan. Since ancient times, Jeju people have called Truth Mt. that Mt. Halla protects against typhoons blowing from the south. It looks like it has been hardened by fire. On the coming day, the greatest breath of Venerable Baltara in Jeju is Olle Road No. 1 from Siheung-ri, Seongsanpo to No. 26 Gujwa-myeon Jongdal-ri. It is the Oval Jeju "Road Way" that clearly shows "the beginning is the end, and the end is the beginning" of Cheonbugyeong.

The study was performed to understand the actual vegetation by using the phytosociological method on the Ambrosia artemisiifolia var. elatior community group in Jeju Island. The flora was composed of 48 families, 156 genera, 200 species, 28 varieties, 2 forma or 230 taxa. The Ambrosia artemisiifolia var. elatior community group vegetation was classified into two communities and one association; Erigeron annuus - Conyza sumatrensis, Bromus tectorum - Bidens pilosa, Setaria viridis - Eleusine indica community and Lactuco indicae - Humuletum japonicae association. Ambrosia artemisiifolia var. elatior community group was wide from the coastal areas up to the elevation of 1500 meter on Young sil of Mt. Halla. The highest dominance of the Ambrosia artemisiifolia var. elatior is 345 meter which is located near Seoneheul-ri Jocheon-eup, on the other hand the lowest one is located 1020 meter near Young-sil of Mt. Halla.

The rainwater samples were collected from the 1100 Site of Mt. Halla and Cheju city during the period of March in 1997 to August in 1998, and the major soluble ions were analyzed. The confidence of analytical data was confirmed by using the comparison methods such as ino-balance, electric conductivity and acid fraction, all of which correlation coefficients were above 0.94. The ionic strengths lower than $10^{-4}$ M, the basis for the pure rainwater, were found in 47% and 38% at 1100 Site and Cheju city, respectively. The precipitations in Cheju city were more influenced by the oceanic effect than those in 1100 Site. The acidity contribution was mainly by $SO_4^{2-}$ and $NO_3^-$ in both areas, and the organic acids have contributed to the acidity with only 5~7%. The neutralization factors by $NH_3$ were about 46% at both 1100 site and Cheju city, whereas those by $CaCO_3$ were 11% and 15% at 1100 site and Cheju city respectively, and the free acidity were both about 35% in average. From the MSA analysis, it was found that the air in Cheju island has been influenced by the pollution from the other areas. The sources of the rainwater components in 1100 Site and Cheju city were also studied with a factor analyzing way, and the most probable factors were found to be anthropotgenic, oceanic, and soil-sourced. The results of multiple regression analysis have shown that $SO_4^{2-}$ was dissolved mostly in the form of $H_2SO_4, CaSO_4 and (NH_4)_2SO_4$, and $NO_3^-$ was in the form of $HNO_3, Ca(NO_3)_2 and NH_4NO_3$.

Somatic embryos were induced through embryogenic callus derived from immature zygotic embryo culture of native Prunus yedoensis in Mt. Halla and regenerated into plantlets successfully. Embryogenic callus was induced most effectively on MS medium with 1.0 mg/L 2, 4-D and 0.1 mg/L BAP at an efficiency of approximately 60% using 45 day-old zygotic embryos after full blooming. Globular somatic embryos were induced from embryogenic callus on MS medium with 1.0 mg/L 2, 4-D and 0.1 mg/L BAP and these globular embryos developed to heart-shaped and cotyledonary embryos on hormone-free MS medium. Normal somatic embryos germinated 49% on 1/2 MS medium and the plants regenerated from the somatic embryos were morphologically normal.

A survey of subalpine zone (altitude is 1, 440-1, 700m) in Mt. Halla, was conducted using 37 sampling plots of l00$m^2$ size. The classification by TWINSPAN and RA. DCA ordination were applied to the study area in order to classify them based on woody plants and environmental variables. And to investigate vegetation deterioration by livestock's and user's impact on subalpine zone, seventeen plots were set up. By TWINSPAN techniques, the plant community were divided into five groups by the altitude. The dividing groups are Abies koreana-Taxus cuspidata community, Rhododendron yedoense var. poukhanense-Rh. mucronulatum var. ciliatum-Sasa quelpaertensis community, Ilex crenata- Elaeagnus umbellata-S. quelpaertensis community, Rh. yedoense var. poukhallense-Juniperus chinensis var. sargentii-Rh. mucronulatum var. ciliatum community and Empetrum nigrum var. japonicum-J. chinensis var. sargentii community. The species divirsity of plant community were decreased severely by livestock's and user's impact.

Background: The Northern Hemisphere forest ecosystem is a major sink for atmospheric carbon dioxide, and the subalpine zone stores large amounts of carbon; however, their magnitude and distribution of stored carbon are still unclear. Results: To clarify the carbon distribution and carbon budget in the subalpine zone at volcanic Jeju Island, Korea, we report the C stock and changes therein owing to vegetation form, litter production, forest floor, and soil, and soil respiration between 2014 and 2016, for three subalpine forest ecosystems, namely, Abies koreana forest, Taxus cuspidata forest, and Juniperus chinensis var. sargentii forest. Organic carbon distribution of vegetation and NPP were bigger in the A. koreana forest than in the other two forests. However, the amount of soil organic carbon distribution was the highest in the J. chinensis var. sargentii forest. Compared to the amount of organic carbon distribution (AOCD) of aboveground vegetation (57.15 t C ha^-1) on the subalpine-alpine forest in India, AOCD of vegetation in the subalpine forest in Mt. Halla was below 50%, but AOCD of soil in Mt. Halla was higher. We also compared our results of organic carbon budget in subalpine forest at volcanic island with data synthesized from subalpine forests in various countries. Conclusions: The subalpine forest is a carbon reservoir that stores a large amount of organic carbon in the forest soils and is expected to provide a high level of ecosystem services.

We investigated seasonal photosynthetic capacity and water use efficiency changes of Korean fir (Abies koreana Wils.) trees located at three sites around the peak of Mt. Halla, Witseorum, Youngsil and Jindallebat. At each sites, we chose healthy and declining individuals to examine the differences of physiological characteristics between them. Net photosynthetic capacity in $15^{\circ}C$ were lower than those of $20^{\circ}C$ and $25^{\circ}C$. The difference of net photosynthetic capacity between healthy and damaged trees was clear in June and August but damaged trees recovered with passing of the time. There was no difference between healthy and damaged trees in September on photosynthetic rate. Generally, water use efficiency (WUE) of damaged trees was higher than healthy trees.

The current study aims to classify types of traditional fur Garments in Jeju into Dusik(hat), dress, Jokui(socks) and accessaries, and examine characteristics of them through demonstrative study focusing on collections of museums in Jeju. Dusik is a kind of hat for protection against the cold, and there are badger leather Gamtaes and cow hair Beonggeojis(fur hats). Especially leather gamtae was used to protect against the cold when people hunted roe deers in Mt. Halla. Beonggeoji was producted in the form of felt with fine hair collected coat-shedding of cows and dogs in spring, therefore it was too warm and practical to be damaged from storm or pressure. Fur coat is a general name of dress made of leather without hair. It is a kind of clothes with a hat worn while taking care of horses and cows. Also people wore dog leather topcoats and cow leather topcoats when they hunted in Mt. Halla. As for Jokui, there are leather Beoseon(socks) made of cow leather, leather shoes in the form of straw shoes, and leather Balle embracing the low half of the body warmly. Accessaries include a rectangular cow leather bag for storing an iron piece for making fire. These traditional fur robs in Jeju not only have practicality for protection against the cold, but also symbolized richness by using leathers of badgers, roe deers, etc. that were previous during that times. Also they used partially cut leather for decoration at the edge.
