The purpose of this research is to establish location models for public service facilities considering efficiency as well as equity. And it suggests the method of spatial evaluation reflected the real world. Finally, this research is applied to the analysis on the optimum location of cultural facilities in Geumsan. This research adopts the expert survey for site selection factors and applys AHP for the relative weights. Secondly, it assorts the urban area by satellite image for the spatial analysis on the real world. Next, it adopts the Location-Allocation Model for the location evaluation and embodies the unequal population distribution according to the location model establishment. Finally, it conducts the more specific spatial analysis reflected the real world through the two methods applications; both spatial analysis(Grid analysis) and Network analysis.

최근 홍수기 유량측정방법은 기존 봉부자를 이용한 접촉식 측정방법에서 영상촬영, 레이더 등 첨단기술을 이용한 비접촉식 표면유속 측정방법으로 변화하고 있다. 비접촉식 측정방법은 각 기술마다 표면유속 측정방법의 차이가 있으나 평균유속환산계수를 적용하여 평균유속을 산정하는 공통적인 과정을 수행한다. 평균유속환산계수는 하천의 각 횡측선 수심-유속분포를 일반적인 분포로 가정하고 표면유속에 0.85를 곱하여 평균유속을 산정한다(Rantz, 1982). 그러나 하천의 측정위치 및 흐름특성에 따라 유속분포가 변화하기 때문에 국내외 많은 연구에서 환산계수의 범위를 0.72에서 1.72까지 제시한 바 있다. 따라서 환산계수 0.85의 일률적인 적용은 실제 유량과 측정 유량의 차이가 발생할 수 있어 측정조건의 적절한 환산계수 산정이 필요하다. 본 연구에서는 20년, 21년 금강의 지류인 봉황천에 위치한 금산군(황풍교) 관측소에서 전자파표면유속계를 이용해 측정한 표면유속과 ADCP를 이용하여 동시 측정한 평균유속의 비교를 통해 환산계수를 산정하였다. 또한 금강 본류의 금산군(제원대교) 관측소에서 저중수위에서 ADCP를 이용하여 측정한 평균유속 분포와 고수위에서 전자파표면유속계로 측정한 표면유속과의 경향성 검토를 통해 평균유속환산계수를 산정하였다. 본 연구에서는 지점의 평균유속환산계수를 단일 값으로 산정하였지만, 추후 하천 흐름특성의 변화를 고려한 평균유속환산계수 산정 기법 개발을 통해 보다 정확한 홍수량을 산정할 수 있을 것으로 판단된다.

The research was carried out to investigate the contamination of stream water by the acid mine drainage originated from the abandoned coal mines and coal waste rock in Keumsan, Chungnam. The pH, sulfate and chemical compositions in the stream water were analyzed. At the polluted sites, the pH of stream water was the strong acid, ranging from 3.46 to 4.29. The pH shows negative correlations with sulfate, manganese, copper, zinc, iron and magnesium concentrations. Sulfate concentrations of the polluted stream water, 236.73-310.53mg/l, had 10 times more than those of the non-polluted stream water. The concentrations of heavy metals, Mn and Fe, in the polluted water were 0.56 - 0.83mg/l and 5.89 - 10.58mg/l, respectively. The Mn concentrations were 20 times higher than those of the non-polluted stream water. Compared with those in the non-polluted stream water, the Mg and Ca concentrations in the polluted stream water were high because of leaching from rock and soil to water by the acidifications. Calculated AMDI(Acid Mine Drainage Index) values are low in the polluted stream water, relative to those of the non-polluted water.

Gravity changes due to variations of groundwater level were measured at a ground water monitoring well, which is located at Kum-san, Korea, from November 2008 to September 2009 using Portable Earth Tide (PET) gravimeter. Groundwater level was monitored simultaneously with gravity observations. To extract gravity information from groundwater, we reduced gravity effect from atmospheric surface pressure, earth tides and its loading effect, polar motion and meter drift. In addition, in June 4, 2009, there was a pumping test at he observation well, and groundwater level and gravity variations were observed together successfully. Observation of gravity along with groundwater level is potentially useful for monitoring of aquifer water mass balance and water resources.

The methodology introduces the establishment of a regional ginseng information system, which combines a ginseng database and GIS functionalities. The use of a database and GIS in the execution of ginseng studies may be expressed as shown in Kumsan-Gun. The process from defining a high-quality ginseng problem to providing advice and suggestions for solution of the problem is carried out through five steps: a) data collection and retrieval of data from a database; b) processing of data and preparing model input using a GIS; c) running a high quality-ginseng model; d) interpretation of model output using GIS; e) visualization and translation of study results for discussion with involved parties and advice to principals. In ginseng management it is necessary to deal efficiently and adequately with occurring ginseng situation and problems. This requires the availability of a ginseng information system based on a GIS in Kumsan-Gun, which provides up-to-date information which is quickly accessible and easy to process.

This study aimed at analyze the Regional Information of Geumsan-gun, Chung-Nam, Korea. The study area, the Geumsan-gun, is located in $35^{\circ}57'{\sim}36^{\circ}17'N$, $127^{\circ}19'{\sim}127^{\circ}39'E$. The Landforms, and Drainage network were analyzed from topographical maps on 1:25,000 & 1:50,000 and field survey. The Climate, Population, Economy, Transportation and etc. were analyzed from regional statistics. The results are as follows: The Centripetal forces of unit areas are not powerful because Geumsan-gun located contiguity with Daejeon metropolitan city. The accessibility of Geumsangun is good and is available for a site of specialized agriculture area.

하천의 본류와 지류가 만나는 합류부 흐름특성은 단일 하천에 비하여 수위, 유속, 경사, 유량 등 복잡한 수리학적 특성이 나타나게 된다. 특히, 홍수기 큰 호우사상이 발생하는 경우 본류와 지류에서 유입되는 각 유량의 크기에 따라 수위에 영향을 미치고 지류와 본류에 배수(back water)가 발생한다. 이러한 배수영향은 합류부 유량 산정에 있어서 매우 복잡한 요소로 작용한다. 일반적인 단일 하천에서는 수위가 증가하면 유량이 증가하여 수위관측소 수위 자료를 기반한 수위-유량관계곡선식을 이용하여 유량을 산정한다. 그러나 합류부에서는 배수영향으로 인하여 수위가 증가하더라도 수면경사가 완만해져 수위-유량관계곡선식 변수인 수위를 이용한 방법으로는 유량산정에 어려움이 있다. 따라서 조석 및 배수 영향 등 고리형 수위-유량관계가 발생하는 하천에서는 ADCP를 이용한 자동유량계측 방법을 채택하고 있다. 그러나 자동유량계측 시설을 설치하기 위해서는 고가의 비용이 발생하기 때문에 경제적 측면만 본다면 주요 지점이 아닌 모든 합류부에 설치하는 것은 어려움이 많다. 금강에 위치한 영동군(양강교) 관측소의 경우 하류 약 400m 우안측에서 유입되는 영동천의 영향으로 호우사상이 발생 할 경우 배수영향으로 고수위에서 상류 금산군(제원대교) 관측소와 첨두유량의 도달시간 및 유량 크기에서 역전이 발생한다. 본 연구에서는 이러한 문제를 해결하기 위한 초기 단계로서 영동군(양강교) 관측소가 위치한 금강과 영동군(초강교) 관측소가 위치한 영동천이 만나는 합류부에 수위계를 설치하였다. 호우사상별 유출에 따른 본류와 지류의 수면경사를 분석하여 배수영향이 시작되는 수위와 수위 상승으로 배수영향이 미미해지는 수위를 분석하여 배수영향 특성을 검토하였다. 이러한 분석은 기존 배수조건에서 왜곡된 유량 자료를 생산하는 수위-유량관계곡선식의 문제점을 개선하여 앞으로 정확한 유량산정 방법을 제시할 것으로 판단된다. 이러한 분석을 통하여 추후 합류부에서 배수영향 조건의 고리형 수위-유량관계곡선식 매개변수로 수위 외에도 수면경사를 고려한 수위-유량관계곡선식을 개발하는데 목적이 있다.

In order to examine the natural distribution variations between groups of the Stewartia koreana, the leaf form characteristics of the investigation sites were analyzed by each group. As a result, the Mt. Kumsan group showed a smaller value in leaf length, width, area, and the number of veins, but not in the petiole length and serration number. Among each character, the coefficient of variation(CV) of the characters excluding petiole length and leaf area was in a comparatively narrow range, from 11.6~17.4%. On the other hand, the CV of petiole length and leaf area between the groups was 34.9% and 28.4% respectively. The CV of these characters within the group was also extraordinary- petiole length showed 29.5~42% and leaf area showed 27.7~40.7%. Also, the simple correlation analysis between 12 leaf characteristics showed that the correlation between leaf width and leaf area was high (r=0.975). The correlations between leaf length and leaf area, between leaf length and leaf width were 0.971 and 0.969, respectively. A negative correlation between angle of leaf base and ratio of leaf length to leaf width was discovered (r= -0.843), meaning that the ratio of leaf length to leaf width decreases as angle of leaf base increases. A cluster analysis was enforced among leaf characteristics of the selected group as a standard on the similarity of quantitative, qualitative measurements. The results showed that at a 0.4 distance level, the subjects could be classified into 4 groups. Group 1 was the Mt. Jogyesan and Mt. Kayasan group, group 2 was Mt. Paegunsan, group 3 was Mt. Unmunsan and Mt. Mudungsan, and group 4 was Mt. Kumsan. At a distance level of 0.6, the subjects were classified into two groups. Group 1 was the Mt. Ktimsan group and group 2 was Mt. Mudungsan, Unmunsan, Paegunsan, Kayasan, and Cogyesan. Especially the Mt. Kumsan group had the smallest value in the leaf characteristics of leaf length, width, area, and the number of veins, showing an obvious difference from the other five groups. There were five principal components that had a meaningful eigenvalue over 1.0 among the 12 extracted components. The explanatory power of the top two main components (leaf length and width) on the total variation was 52.7%. The explanatory power was 91.3% when all 5 main components were included.
