To investigate the structure and the conservation strategy of Nature Ecosystem Preservation Area, 65 plots(10m$\times$10m) set up with random sampling method were surveyed. five group -Larix leptolepis Community, Quercus mongolica-Fraxinus rhynchophylla Community, Fraxinus rhynchophylla-Quercus mongolica community. Quercus mongolica-Acer pseudo-sieboldianum community, Quercus mongolica community were classified by cluster analysis. High positive correlations was proved between Quercus mongolica and Sorbus of alnifolia, Acer Mono, Lonicera praeflorens, Sorbus commixta ; Acer mono and Lonicera praeflorens, Sorbus commixta ; Maackia amurensis and Acer triflorum ; Fraxinus rhynchophylla and Betula davurica ; Lonicera praeflorens and Cornus controversa, Sorbus commixta ; Acer triflorum and Rhamnus toshinoi ; Pyrus ussuriensis and Prunus padus ; Cornuscontroversa, and Sorbus commixta, and high negative corrlations was proved between Quercus mongolica and Larix leptolepis, Carpinus cordata ; Tilia amurensis and Larix leptolepis, Morus bombycis. Species diversity(H' ) of investigated groups were ranged 0.4443~1.2036.

A hierarchical representation scheme for planar curves, MBO-tree, is proposed in this paper, which provides natural approximation and efficient localization. MBO-tree is based on the Douglas-Peucker algorithm (iterative end-point fit algorithm), but approximation errors that are stored with corresponding points in MBO-tree nodes and are used for abstraction measures are adjusted by force to eliminate unnatural approximation. The error adjusting is just making the approximation error of a node in a MBO-tree to be less than or equal to that of its parent. In point of localization, the bounding area of a curve is represented with a minimum bounding octangle (MBO), which can enclose the curve more compactly compared with those of other hierarchical schemes, such as the strip tree, the arc tree and the HAL tree. The MBO satisfies the hierarchical inclusion property that is useful for hierarchical geometrical operations, such as the point-inclusion test and the polygon intersection test. Through several experiments, we found that the proposed scheme was able to approximate more naturally and to localize more effectively.

In this study, intention type was assigned to determine appropriate conservation and use of the Baekdudaegan Protection Area. To determine intention type, 84 indices were integrated into 7 types: the Natural Environment Protection District, Natural Scenic District, Agriculture and Forestry Promotion District, Living Environment Protection District, Education/Culture/Arts Promotion District, Recreation/Tourism Promotion District, and Disaster Management District. Intention types were decided by comparing the occupying proportion of the intention types for each watershed segment in which the Seoraksan, Taebaeksan, and Sockrisan region boundaries were included. Weight values were applied to each of the seven intention types because each type did not play an equal role in the target regions. Most regions were classified as Natural Environment Protection intention types because the Baekdudaegan area is regulated with strong forestry and environmental protection acts; thus, the weight values related to nature protection were higher than those for other types. To supplement the results from this study, additional research is needed to determine the intention type and weight for each region, and it will also be necessary to integrate sociocultural factors and field survey data.

현재 호남지역에 사상 유례없는 폭설이 내려 피해를 입은 지역들은 거의 회생불능 상태에 빠져 있다. 이에 피해를 입은 지역들은 특별재난지역 선포를 요구하고 있고 정부는 선포기준과 타 지역과의 형평성을 고려해 특별재난지역 선포에 난색을 표하고 있다. 더욱 문제가 되는 것은 자연재해로 인한 피해가 발생 할때 마다 정부와 피해 지역민들은 재해 복구에 대한 이견 차이로 사회 · 경제적 비용이 낭비되고 있다는 점이다. 이에 이번호에서는 우리나라 농업재해 대책의 현주소를 알아보고 이를 해결할 수 있는 대책은 없는지 살펴보고자 한다.

지방자치단체는 지방자치제 실시이후로 많은 지역축제가 개최되어 왔으나, 대부분의 소재가 특산물와 자연환경을 소재로하여 개최되었다. 다른 요소들보다 지역축제의 소재를 찾기 쉬운 점에서 눈에 보이는 소재를 이용했다고 볼 수 있지만, 지역축제를 개최하는 데 있어 소재에 대한 중요성이나 파급효과에 대한 심도있는 자기 지역만의 특색있는 소재를 찾는 노력에서는 문제점을 지적하지 않을 수 없다. 자기 지역을 대표할 수 있고, 다른 지역에서 흉내낼 수 없는 자기 고장만의 소재만이 관광객을 지속적으로 유치할 수 있는 유인요소가 될 것이기 때문이다. 따라서, 본 연구에서는 문학작품과 관련된 소재를 개발하고, 관광객을 유치할 수 있는 방안을 제시하는 데 목적이 있다.

I. 서론 아시아 대륙의 동북쪽 변두리 그것도 뒤에는 대륙을 짊어지고 앞에는 넓은 바다를 안고있는 동북아시아의 생활환경을 살펴본다. II. 역사환경 1. 동북아시아권에 속하고 있는 지역들은 모두가 그 나라들의 변두리 지역이다. 2. 이 지역들은 여태까지 방치되고 있던 불모지이다. 3. 이 지방들은 정치체제들은 각각 다르나 주로 자연에 의존하면서 살아온 지역들이다. 4. 이 지역들은 식민지.미개지로 여태까지 개발되지 못한 지역이므로 새로운 개발 계획으로 서로 권역을 형성하여야 하는 지역들이다.(중략)

What distinguishes Impression Liu Sanjie, directed by Zhang yimou from other stage performances lies in its use of space. Firstly, it breaks the regular way of performing in a limited theater space but instead, impression Liu sanjie bases the stage activities on the real nature scenery. Secondly, it promotes the local culture by combining the unique color effect of the particular nature scenery with its use of the scenery's natural space, with an aesthetic precision. In another word, Impression Liu Sanjie is not a simple performance set on the natural scenery but more of a promotion to the local culture, through the concept of "environment friend" between human and nature, which is brought by mixing the unique color of natural scenery and its natural space. This research analyzes the Impression Liu Sanjie's use of space basing on Proxemics by Edward T Hall. Impression Liu Sanjie adapts its character from a folk tale, employs the form of natural scenery performance, and at the same time to the largest extent throughout its creating process respects the local culture and its natural space. As a result, the performance presents the idea of "environmentally friendly".

In this study, the efficiency of natural attenuation was evaluated through the hydrogeological characteristics such as monitoring and analyses, tracer tests, chemical composition analysis of the groundwater at a military site contaminated by petroleum hydrocarbon in korea. Also, based on the results, the natural attenuation rate by distance and the expressed biodegradation capacity(EBC) was evaluated. The regression slope of -0.0248($K/V_x$) and bulk attenuation rate of $1.7{\times}10^{-3}/day$ were calculated respectively. The range of total expressed biodegradation capacity(EBC) of BTEX was shown from 9.1 mg/L to 10.0 mg/L(average 9.7 mg/L). It was confirmed that the denitrification which was expressed about 63.6% in the total EBC is the largest influence redox process. Consequently, the biodegradation capacity is considered to be sufficient for remediation in the BTEX average concentration of 1.326 mg/L.
