We investigated 12 plots using Herles` diversity of structure feature calculation method, which is based on the Shannon Weaver Index for estimation of species diversity. This study sought to facilitate a more systematic understanding of the structure of the forest stands in the Korean fir natural forest in Naeseorak. Although the change in the forest structure is dependent on the change in phase, factors of the natural forest were confirmed by associating individual structure features. As shown in the results of diversity of structure features, the diversity of the structure of the fir tree natural forest in Naeseorak was relatively low. The association between species diversity and overall factors (diversity) related with the change in the structure was found to be weak. The association between the number of trees and the diversity of forest structure stands was moderate, showing that the higher the number of trees, the less diverse the forest structure is. In most of the investigated plots, stem volume and volume of dead tree were associated with the height of natural regeneration, but these were not associated with other factors. Height of natural regeneration was found to be correlated to stand density, crown area and crown class, whereas tree height and BHD did not have any association with other factors. Overall, the results of the investigation are helpful in understanding the change in the structure of Korean fir natural forest. Further investigation with more plots is required.

Paraffin wax is used for mask and bath in skin care and medical therapy. In this study, optimal temperature and skin improvement effect of paraffin wax such as stimulation of micro blood circulation and removal of sebum and keratin was investigated in women in the 20`s. Paraffin wax was spread first 5 layers and 10 layers at 50~55oC on inner wrist to observe potential temperature. Second 5 layers paraffin wax mask were applied twice/week in 4 weeks on dry facial skin of 7 women. Content of moisture and sebum were measured, and pore amount/size, skin surface temperature and skin improvement of keratin remove and texture were observed. In the result, potential temperature of paraffin wax was revealed in 5 layers at 52~53oC. After 8 times application of paraffin wax mask, moisture and sebum content were increased to 6.0% and to 12~19% before application. Face surface temperature were significantly increased to 3.7oC, and fine and large pores were significantly decreased to 234.6 pieces and to 69.7 pieces before application(p<0.05). Removal of keratin and crusts, improvement of skin texture and ton were observed after paraffin wax mask application. In conclusion, paraffin wax mask could have not only thermal effect but also deep cleansing effect and may be very useful in skin care.
내설악 전나무림 천연갱신과 임분특성 -전나무 자연림에서 천연갱신에 대한 개념적 고찰을 중심으로-

전나무의 천연갱신 형태를 임분의 특성과 연관하여 내설악 길골 총 30지역에서 조사하였다. 임학적 의미의 천연갱신은 주로 예전에 인공적 교란이 있었던 곳에서 나타나며 자연림의 특성이 강할수록 오히려 의미를 상실한다. 이것은 인공적 교란이 천연갱신에 더 나은 환경조건을 제공하기 때문으로 보인다. 이와는 달리 자연림에서 갱신단계는 인공림처럼 명확할 수 없고 잠시 나타났다 사라지는 상태이며 세대교체는 임분구조 변화의 일부라는 표현이 적합하다. 특히 patch dynamic이 임분구조를 결정하고 주 구성수종이 음수인 전나무 자연림에서는 인공림에서 사용되는 천연갱신 개념은 원천적으로 의미를 상실할 것으로 보인다. We surveyed the total 30 sites in Gilgol, Nae Sorak for the patterns of the natural regeneration of the korean fir in connection with the characteristic of the stand. The natural regeneration in a forestrical meaning is not found in natural forest but mainly in the anthropogenically already disturbed area. It may be inferred from this fact that the anthropogenic disturbance can give more better condition for a natural regeneration. The regeneration phase in the natural forest is not so distinctive as the artificial forest, and shows itself transiently. And it may be also said that a shift in generation is only a part of the change of the stand phase. The concept of the natural regeneration will lose its meaning, in so far as the patch dynamic determines the phase of the stand, and the main tree species are shade-tolerant abies.

Safety of passengers in the Korean High Speed Train, KHST, was evaluated under the different accident scenarios. Preliminary occupant analysis has been performed based on the TGV-K train seat characteristics. The influence of the vehicle deceleration and passenger type, seating positions, effectiveness of compartmentalization have been evaluated in terms of occupant injury criteria. This study is the final result of the occupant analysis of KHST project at 1st stage 3rd year.

The convention industry, a very high economic value-added industry, is an environment-friendly field of the tourism industry and is recognized as having high potential for further gaining its importance in the future. This study analyzes and examines on the cultural tourism Outcomes of Gyeong-Ju·An-Dong. And discovering problem of system from evaluation, there is ultimate purpose though wish to contribute in development of cultural tourism of Gyeong-Ju·An-Dong. Therefore, the purpose of this study is as following. First, I wish to find key performance indicators to display cultural tourism of Gyeong-Ju·An-Dong in financial performance measurement and non-financial performance measurement. Second, decide key performance indicators` importance to use AHP method. Third, develop model that can estimate cultural tourism of Gyeong-Ju·An-Dong`s competitive power through Fuzzy Set Theory. Fourth, do empirical analysis about cultural tourism of Gyeong-Ju·An-Dong through developed model.
