정부와 민간이 대단위 택지 개발사업을 추진하면서 그 지역의 기후조건 및 자연환경 등을 충분히 고려하지 못하고 획일적이고 평면적인 단지를 조성함으로써 대도시의 대단위 아파트 지역에서 여름철, 강한 일사량과 약한 풍속으로 인한 일시적인 역전현상 및 열섬효과로 인하여 주변지역에서 배출된 대기오염물질들의 확산을 저해하는 요인이 되고 있다. 또한 대단위 아파트 단지조성 시에 도로와 아파트 대형건물의 배치 등 기류이동을 고려하지 않고 건설하므로 주위의 오염물질이 풍향 및 풍속에 따라 단지 내에 정체하여 건물의 실내로 들어가 또 다른 실내오염을 야기 시키게 된다.

The remains of the Bronze Age in Chuncheon region are mostly distributed on the floodplain. The floodplain in this region is made up mainly of natural levee that is high in height and is not flooded with water. The natural levee has very advantageous conditions in agriculture compared with other places. There is a high possibility that people in Chuncheon region during the Bronze Age inhabited on the floodplain and engaged in agriculture. Considering the geomorphic features and soil of natural levee, it is believed that the agriculture centered on dry-field farming was done in this region at that time.

In this paper, a new meshfree technique which improves the numerical integration accuracy is introduced. This new method called thc Petrov-Galerkin natural clement method(PG-NEM) by authors is based on the Voronoi diagram and the Delaunay triangulation which is based on the same concept used lot conventional natural clement method called the Bubnov-Galerkin natural element method(BG-NEM). But, unlike the BG-NEM, the test basis function is differently chosen, based on the concept of Petrov-Galerkin, such that its support coincides exactly with a regular integration region in background mesh. Therefore, it is expected that the proposed technique ensures the remarkably improved numerical integration accuracy in comparison with the BG-NEM.

과거 치수적 목적에 의해 진행하던 하천정비방식이 최근에 친환경적 개념의 정비방식으로 전환되면서 하천환경개선에 대한 관심과 공감대가 증가되고 있다. 일부 지자체를 중심으로 하천살리기 운동을 비롯해 하천의 환경기능을 개선하려는 노력이 진행중이며 전국적으로 자연형 하천정비 또는 친환경적 하천복원 등의 사업이 활발히 시행되고 있다. 자연형 하천정비 개념의 도입이후 많은 하천에 다양한 자연형 호안공법이 시공되어 가고 있는 상황에서 보다 적합한 호안공법의 적용을 위해서는 하천의 환경특성을 고려할 필요가 있다. 이는 대상 하천이 지니는 특성에 적합한 호안공법을 선정하는 데 선결되어야 할 문제이며, 적용 호안이 시공 이후 하천환경과 얼마나 조화를 이루는가를 담보할 수 있는 방안이라 할 수 있다. 따라서 본 연구에서는 상기의 조건을 만족시킬 수 있는 호안에 대한 평가를 위해서 광주천을 대상으로 하여 호안에 대한 평가를 실시하였다. 대상하천인 광주천은 광주시를 관통하는 도시하천으로, 현재 자연형 하천정화사업을 시행하고 있으며 2009년에 완공될 예정이다. 광주천의 호안에 대한 평가를 위해 수리적 안정성, 식생의 건전성과 경관/심미성 및 생태성을 포함한 평가방식을 개발하고, 개발된 기법을 광주천에 적용하여 하천공사 전후의 호안을 평가하고 그 결과를 비교함으로서 호안평가 방법을 확립하는 것이 본 연구의 목적이다.

The number of campers has been consistently growing thanks to the introduction of a five-day work week and the time increase for a leisure. Thus, many types of facilities for camping are constructed. For instance, there are gravel camp site, which is called crushed stone, and normal soil camp site in case of private camp sites. The amount of natural background radiation, measured from site to site, was analyzed. The value of soil camp site was lower than that of crushed stone camp site. And the amount of natural background radiation from normal camp site was also lower than that from the artificial shade made by tarp. Consequently, it is noted that normal soil camp site with the plenty of woods should be chosen for camping place in order to avoid natural background radiation.

With the increase in leisure life, the population of ski resorts is rapidly increasing. The activity at the ski resort is likely to receive a direct chance of natural sunlight or space ray. Because it is located in the mountains where altitude exists. As a general rule, it is widely known that the higher the elevation rate, the more increasing the natural radiation dose. However, the natural radiation dose rate for the ski slopes has not been reported yet. Various ski resorts exist in Korea, but this study had chose 4 ski resorts to measure the natural dose of natural radiation. As a result, the natural radiation dose for the ski slope was measured at a relatively high dose of ordinary living areas. However, the level of natural radiation dose was not worrisome. It is recommended to wear ski wear or goggles to minimize natural radiation exposure at the ski slopes.

River plays an important role both to nature and people. Also considering the limitation of land and water resources coupled with the continuous urbanization and industrialization of Korea, the effective river management becomes more and more important. The evaluation units consisted of main 3 factors(13 detail factors) are classified 5 grade and 5 scores system. The survey area was divided and selected by 5 zones in Musim-cheon river. The final result of evaluation for 5 Zone is good near natural river following next order; 1 (4.07), 2 (3.56), 5 (3.4), 4 (3.1) and 3 Zone(2.6 score) On this condition, the main purpose of this study was to apply GIS(geographic information system) spatial analysis for evaluation method of river naturalness in order to promote the river management and the process of ecological restoration of river corridors.

어저귀는 사료용 곡물 수입시 혼입되어 사료작물 포장 중 옥수수밭에서 많이 발생된다. 효과적인 방제법은 토양처리제와 경엽처리제로 처리하여 밀도를 줄여나가는 것이다.
