This study was conducted to obtain the basic information about Siberia Musk Deer (Moschus moschiferus), and to establish a conservation area for the replacement of Siberia Musk Deer into Mt. Odea National Park, South Korea. We analyzed the main habitat for Siberia Musk Deer restoration in Mt. Odae National Park, Korea. We recorded Siberia Musk Deers' field signs (i.e., bedding sites, feeding areas, feces and tracks), and habitat variables such as nearest distance to the watercourse, trails, slope, aspect, forest type and land cover etc. from Dec. 2004 to Aug. 2007 in Mt. Jiri, Mt. Seorak, and Demilitarized Zone (DMZ). Rocky areas, ridges, mixed coniferous forest (Red pine and Mongolian oak), southern and southeastern slope, elevation of above 800m, and distance from watercourse shorter than 300m etc. were dominant habitat types of Siberia Musk Deer. Based on the significant habitat types, a proper conservation plan should be prepared for the restoration of habitats in order to reintroduce, and to increase the population of Siberia Musk Deer in Mt. Odea National Park, South Korea. Small population size, and limited ecological data are the major constraints for the establishment of conservation areas. Furthermore, other anthropogenic factors including human activities, poaching, and residential area around the park caused the difficulties to qualify as a conservation area. For the successful establishment of conservation area in the future, it is recommended to conduct a comprehensive ecological research, and to survey human disturbances including their impacts on the habitats of Siberia Musk Deer in the Mt. Odea National Park.

This study was conducted to investigated woody species community classification and understory vegetation characteristics of Abies nephrolepis forest in Mt. Gyebang and Mt. Odae designated as Protected Area for Forest Genetic Resource Conservation and National Park. Vascular plants were surveyed as following; 55 family, 148 species, 3 sub species, 14 variety, 2 form 167 taxa. As an analysis of the species estimator of Jackknife 1, 29 survey plots could be representative of vegetation in study site. Results of the woody species, 3 communities were divided by cluster analysis(A=Abies nephrolepis-Tilia amurensis, B=Betula ermanii-Abies nephrolepis, C=Quercus mongolica-Abies nephrolepis). Using MRPP-test, there were significant differences between the communities indicating analysis of the appropriate group classification(p<0.01). The basal area and altitude were analyzed by negative relationship for NMS ordination. By analyzing plexus diagram of woody species, Acer pseudosieboldianum is strong associated with Quercus mongolica and Rhododendron schlippenbachii. Magnolia sieboldii is strong associated with Acer pictum subsp. mono etc.

The outbreaks of blast, bacterial blight and viral diseases have been increasing in early maturing rice cultivating areas in the central northern regions, recently. As the occurrence of sudden insects pests and disasters increases due to global climate warming, it is urgent to develop a variety of disaster-tolerant, high-quality varieties in response. This study was carried out to elucidate the characteristics of early-maturing, high-quality and multiple disease resistant rice variety, Cheolweon109 that was adapted to cultivation in the mid-mountainous regions of the central northern regions. Cheolweon109 was derived from a cross between Suweon546, medium maturing variety, and Sangju44 which is early maturing and resistant to blast, bacterial blight and rice stripe virus. The heading date of Cheolweon109 was July 30, 3 days later than Odae. The culm length of Cheolweon109 was 79 cm, which was about 5 cm taller than Odae, and the ripening ratio was 85.1%, which was 10% higher than that of Odae. This variety had 5.54 MT/ha of milled rice productivity, which was 99% of the Odae. Although Cheolweon109 was tall, it was strong against lodging. It was strong against bacterial blight (K1, K2, K3 race), rice stripe virus, and the pre-harvest sprouting which rate was 2.4%. The appearance of the grains of rice was clean, the glossiness was 70.6, and the head rice ratio was 95.3% high. Because Cheolweon109 had superior disease resistance, disaster resistance, and high quality than Odae, it was expected that can be used to expand the diversity of early maturing and high-quality rice varieties in central northern regions.

The successional status and potential natural vegetation were examined in a mixed broadleaved-Abies forest located at Mt, Odae National Park. The examination was based on the subsequent process of generation replacement by understory saplings for the dominant canopy trees within 88 $5m{\times}50m$ belt transects. The transition matrix model, which was modified from mathematical theory of Markov chain, was employed to analyze the successional status of the study forest. The model suggests that the study forest is still seral, and it is considered to be more than 700 years away from the steady state or climax in terms of species composition. The simulations predict a remarkable decrease in the proportion of species composition of the present dominant Quercus mongolica and Tilia amurensi.s from current 28% and 13% to less than 3% and 5%, respectively, at the steady state. On the contrary, the proportions of Abies holophylla, Acer pseudo-sieboldianum, Carpinus cordata, and Pinus koraiensis will increase at the steady state. The ratio of mixture between deciduous and coniferous trees will be gradually changed from current 6.5 : 3.5 to 5.0 : 5.0 at equilibrium. Discussion for the problems of Quercus mongolica in successional status noted that the species behaved as a mid-successional dominant, not a climax species in the study forest. The hypothesis and sensitivity of the transition matrix model were also discussed to evaluate the applicability to the real situation. The overall results indicated that the present dynamics of the forest must reflect the seral state due to previous disturbance mainly by hyman related interference.

The purpose of this research was to propose policy directions for the design and construction of nature-friendly park facilities (PF) in national parks. In order to do that, nature-friendliness evaluation indicators(NEIs) used in green building rating systems and related articles were reviewed. After the initial literature review was complete, NEIs for park facilities based on location, design, construction, operation, and management sectors were developed. Data was obtained through a questionnaire completed by 79 managers at 19 national parks in Korea in 2008. The answers were analyzed using descriptive statistical methods, a t-test, a multi-dimensional analysis, and a factor analysis. This research found that: 1) The results indicated that based on relative weight calculation, the location condition was evaluated as the most important; 2) The evaluation results regarding the degree of nature-friendliness of park facilities showed that location condition was ranked higher than design and construction--in addition, the evaluated values of indicators related to energy efficiency were ranked the lowest; 3) the level of nature-friendliness of shelter was given the highest level, but resting facility was the lowest level; 4) Overall, park facilities at Mt. Seorak, Mt. Odae, and Taean Coast national parks showed high levels of nature-friendliness. But park facilities at Mt. Gyeongju and Mt. Songni national parks showed low levels of nature-friendliness. The results of this research shall contribute to the establishment of tailor-made management policies, the development of detailed guidelines for increased energy efficiency and visitor satisfaction, and the preservation of ecosystems and natural resources in Korea's national parks.

This study aims to compare and analyze the environment of natural parks and Ulleung island using the plant taxa classified by five degrees based on their distributional ranges. The scores differentially given based on the importance of each degree; taxa belonging to the fifth degree are given to 20 scores each, fourth 10, third 5, second 3.3, and first 2.5, respectively. The total assessed scores were ranked as Mt. Halla, Seorak, Jiri, Deokyu, Is. Ulleung, Mt. Sobaek, Odae, Palgong, Chink, Taebaek, Songni, Juwang, Gaya, Duryun, Gaeryong, Bukhan, Naebyeon, Worak, Naejang, Cheongryang, Naeyeon, Myeongii, Jokye, Mudeung, Wolchul, Geumo, Juheul, Biseul, Hwangmae, Jangan, Seonun, Moak, Seonam, Chilgap, and Gibaek, in order, respectively. It is suggested that the natural environments assessing more than 1,000 of total scores such as Mt. Halla and Mt. Deokyu are regarded as the most excellent ones, and those between 700 to 1,000 of total scores such as Is. Ulleung and Mt. Odae are regarded as relatively excellent ones. Natural parks scored between 500 to 700 such as Mt. Palgong and Mt. Gaya are regarded as good ones and parks scored between 300 to 500 such as Mt. Duryun and Mt. Mudeung are regarded as normal ones. The area assessed less than 300 of total scores such as Mt. Wolchul and Mt. Gibaek are regarded as the most inferior ones. The total scores of the national parks are generally higher than those of the provincial and county parks. In addition, Ulleung island has a total of 882.9 scores. Therefore, according to the IUCN the Ulleung island should be included in the criterion of the preservative model of natural ecosystem, suggested by Ministry of Environment. At the same time, Ulleung island should be included to the superior model of natural scenery resources by its uniqueness of topography, geography and natural environments. Ulleung island is assessed as having relatively excellent natural environments as compared with other national parks, suggesting that the island should be designated as a new national park.

Pholiota sp. were collected from the forest of Kangwon province (Mt. Samak, Mt. Odae and Kangwon National University Forest Experimentation) from the early of August to the end of October 1997. Among these fungi, Poliota adiposa was selected for culture experiment because it is suitable for edible mushroom. The Optimal temperature for the mycelial growth of Pholiota adiposa was in the range of $28^{\circ}C$ while that of fruit body formation was $15{\pm}1^{\circ}C$. Brown sugar as carbon source and soybean flour as nitrogen source were good for mycelial growth in commercial liquid culture. The fruit bodies of Pholiota adiposa were artifitially produced on plastic bottle including poplar sawdust and rice bran (4:1).
