본 연구는 전형적인 비도시 유역인 화옹유역을 대상으로 토지이용과 인구 및 축산의 사육두수를 이용하여 수질항목과의 상관분석을 실시하였다. 화옹담수호로 유입되는 3개의 주요하천의 수질을 평가한 결과 남양천의 N1과 N2지점과 어은천의 E3지점이 특별한 관리가 필요한 것으로 평가되었으며, 이 지점에 설치중인 하수처리장이 완공될 경우 화옹담수호로 유입되는 하천수질개선과 담수호로 유입되는 부하량이 상당히 감소할 것으로 판단된다. 토지이용과 하천수질과의 상관성 분석결과 주거지역의 경우 양의 상관관계를 보였는데, 생활하수의 유입이 직접적인 원인인 것으로 판단되었다. 비도시 유역에서는 형성된 주거지역의 정화조의 정비와 하수처리장 신설, 하수관거 정비 등의 관리가 필요하며, 본 연구지역과같이 하구담수호가 위치한 지역에서는 더욱 중요하고 간척지토지이용에서도 고려해야 하는 사안이다. 논의 경우에는 수질항목들과 유의성을 갖는 음의 상관관계를 나타내었는데, 논은 오염물질을 배출하는 측면보다 하천생태에 좋은 영향을 미치는 것으로 평가되었다. 인구와 수질과의 상관분석결과 낮은 상관성을 나타내었으며, 단위면적당 인구수로 분석했을 때에는 비교한 결과 높은 상관계수를 나타내었다. 따라서 인구수로 유역의 오염물질 배출을 평가하기 보다는 밀도를 고려해서 평가하는 것이 합리적이다. 축산의 경우는 단위면적당 오염원을 고려하여 평가한 경우 사육두수로 평가하는 것 보다 합리적인 결론을 보였으나 상관성은 높지 않았다. 본 연구는 토지이용과 인구와 축산 등 오염원자료를 이용하여 수질항목간의 상관성을 분석한 결과이며 비도시 유역의 오염부하특성을 이해하는데 도움을 주며, 유역특성이 유사한 지역에서는 본 연구와 유사한 방법으로 유역내 오염원 특성을 파악하여 합리적인 관리계획을 세우는데 응용할 수 있을 것으로 판단된다.

서울시의 대기오염을 지속적으로 모니터링하기 위해, 그동안 환경부는 운영하고 있는 대기오염 측정망을 지속적으로 발전시켜왔다. 측정되는 대기오염 물질 중 미세먼지는 인체에 상당한 영향을 미치는데, 우리나라의 오염도는 OECD 국가 중에서도 두 번째로 높은 편이다. 따라서 본 연구에서는 측정된 미세먼지 농도 자료를 이용하여 서울시의 미세먼지 분포도를 PM10과 PM2.5에 대해 작성하고, 미세먼지 농도의 분포에 영향을 미칠 것으로 예상되는 공간적인 요인들과의 관계를 조사하였다. 반경 500m의 원을 포함하는 헥사곤을 기준단위로 하여 서울 전역을 구획화하고 보간법 중 거리반비례기법을 이용하여 미세먼지 농도분포도를 작성하였다. 출, 퇴근 시간대의 미세먼지 농도분포를 지역별로 분석하고, 토지이용도 및 교통량과의 관계를 분석하였다. 분석결과, PM10과 PM2.5의 농도분포는 지역별, 시간대별로 각기 다른 패턴을 나타내었고, 토지이용형태 측면에서는 상업지역 및 교통지역의 면적이 미세먼지 농도분포와 높은 관련성을 보였으며, 녹지의 유무도 농도의 분포 변화에 관계가 있는 것으로 판단되었다. 추후 세부적인 토지이용도 및 녹지분포도 등을 통하여 상관관계를 분석하면 미세먼지의 농도에 영향을 미치는 지역 수준에서의 공간요소를 밝히는데 도움이 될 것으로 기대된다.

The purpose of this study is to suggest diagnosis indicators and checklist for urban regeneration projects by Korea Land & Housing Corporation(LH). There are already deprivation indices in the Urban Regeneration Act but not any additional guidelines in the practical aspect. In order to use the diagnosis indicators, the central government should supply more specific checklist to the actors in the regeneration field. The key actor of many stakeholders is LH as an operator and implementer in the regeneration projects. So far, LH has developed housing and cities and there haven't been any obvious changes to realize public benefit in the deteriorated area. From now on, It has to plan, implement, and manage a lot of regeneration projects entirely. Therefore, It is necessary to develope and apply the diagnosis indicators and checklist based on projects. This paper came up with the 6 factors related with LH business field : housing, urban infrastructure, public service, private service, environment, and smart city. For these, 32 diagnosis indicators and 72 checklists were selected that can include both physical and qualitative indicators. These can be used not only for the selection of regeneration projects but also for the process monitoring such as planning and implementation.

The remote monitoring system of water salinity was assessed in Wando reclaimed land lake during a farming season in 2009. Increasing of water salinity in this lake used to bring about salt damage on rice plant occasionally. At the early stage of the rice growing period, rice growth was not damaged due to enough rainfall with more than 120 mm from the mid-May to the first ten days of June. Data collection using on-site water salinity measuring sensors every 2 hours and real-time transmission in system were carried out for the experiment. We compared the transmitted values from the sensor system with water sample values collected and analyzed by a local technical office. Salt concentrations measured by sensor in real-time monitoring system were available data. The regression equation between rainfall and water salinity was presented as (water salinity after rainfall) = $0.621{\times}$(water salinity before rainfall)${\times}exp(-0.0139{\times}rainfall)$, ($r^2=0.579$, p<0.01). It is suggested that the system is useful for stable farming in the area where farmer use water in reclaimed lakes as an irrigation source.

Converting the agricultural land-use of rice field to upland has been increasingly conducted as farmers encourages themselves to grow higher value-added crops on rice fields under the policy support. Comparing to rice field, Upland shows different characteristic of discharge due to the slope, scale, and shape of field and characteristics of rainfall event. In this study, we designed the experiment fields reflecting flat-upland characteristics with different land scale, and tried to collect the discharge and load data. Soybeans and corn were selected as target crops considering the possibility of large-scale cultivation and crop demand. The cultivation was conducted during the growth period in 2019 with 3 different field scales. Hence, we have collected the discharge data from 17 rainfall events and the load data for 8 rainfall events. As a result, the magnitude of rainfall events and the discharge duration were found to have a strong positive correlation and field discharge occurred during the period by 55% to 83% of rainfall duration. Besides we found other relationships and characteristics of rainfall event, discharge, and pollutant load and also pointed out that continuous monitoring and more data are required to derive statistically significant results. Compared with slope-field monitoring data obtained from the precedent research, the runoff ratio of the flat-fields was significantly lower than slope-fields. Overall the discharge in the slop and flat-fields shows appreciably different characteristics so that the related researches need to be further conducted to reasonably assess environmental impact of agricultural activities at flat-field.

The Earth, along with its major components - land, atmosphere, and oceans, is at the core of the global environmental system. Changes in any component of the Earth thus strongly affect the global and regional environment. With the advent of the new century, many important decisions on agricultural, industrial, societal and political problems will depend upon the Earth's environment. Monitoring the Earth is thus important to capture any sign from the Earth which might be related to the environmental change. (omitted)

Considering the risk management, there are many examples and various studies for the corporation risk. However, I have never seen the project risk management that applied a construction site for practical approach. Therefore, I have developed a chart (I-Chart) for the project risk management, and also built a model (I-Chart scenario analysis) that I could use. I applied this model to container yard reclaimed land in harbor construction with approaching of geotechnical engineering.

It is important to analyze the seasonal change profiles of land cover type in large scale for establishing preservation strategy and environmental monitoring. Because the NOAA-AVHRR data sets provide global data with high temporal resolution, it is suitable for the land cover classification of the large area. The objectives of this study were to classify land cover of Korea, to investigate the phenological profiles of land cover. The NOAA-AVHRR data from Jan. 1998 to Dec. 1998 were received by Korea Ocean Research & Development Institute(KORDI) and were used for this study. The NDVI data were produced from this data. And monthly maximum value composite data were made for reducing cloud effect and temporal classification. And the data were classified using the method of supervised classification. To label the land cover classes, they were classified again using generalized vegetation map and Landsat-TM classified image. And the profiles of each class was analyzed according to each month. Results of this study can be summarized as follows. First, it was verified that the use of vegetation map and TM classified map was available to obtain the temporal class labeling with NOAA-AVHRR. Second, phenological characteristics of plant communities of Korea using NOAA-AVHRR was identified. Third, NDVI of North Korea is lower on Summer than that of South Korea. And finally, Forest cover is higher than another cover types. Broadleaf forest is highest on may. Outline of covertype profiles was investigated.
