  • Increasing concern for the environment in Korea has led to the demand that major policies and large-scale development projects be subjected to detailed impact assessment. This paper reports on the state of data related to the prediction of the environmental impact (EIA) to emphasize the importance of data quality. Environmental impact statements (EIS) consulted with the Ministry of Environment of Korea were analyzed from 1981 through 1992. Many of assessors used existing data and collected supplementary data from field survey. Most of the results of EIA are presented directly or summarized on maps and as graphics. For the national purpose, large source of quality-controlled data such as atmospheric data have been developed, However, there are the deficiency in data to analyze the impact of human activity, and data gaps and incompatibilities among systems. Consequently, the development of data bank systems including computer database and remotely-sensed satellite data is required to improve the quality of data which are relevant to EIA. The data bank system should be organized meaningfully in minimum time with a least cost, and measurement standards must be made explicit. Geographical information systems (GIS) are applicable to the graphic presentation or to the impact prediction model.

  • Oceanic pycnocline depth is usually obtained from in situ measurements. As ocean internal waves occur on and propagate along oceanic pycnocline, it is possible to estimate the depth remotely. This paper presents a method for retrieving pycnocline depth from synthetic aperture radar (SAR) imagery where internal waves are visible. This model is constructed by combining a two-layer ocean model and a nonlinear internal wave model. It is also assumed that the observed groups of internal wave packets on SAR imagery are generated by local semidiurnal tides. Case study in East China Sea shows a good agreement with in situ CTD data.

  • This study was conducted as a preliminary study for the mitigation of acid rain which has been a serious environmental problem in both regional and global scales. In this study, sulfur dioxide emission was estimated at city and gun(county) level. Also, this study represents the estimated sulfur dioxide emission with using a geographical information system which includes administrative boundaries. The results of this study are expected to serve as a sulfur dioxide emission mitigation policy guidance and a basis of a future emission model and a comprehensive global warming model. Moreover, thanks to the geographical information system, the results are also expected to help carrying out clear policy goals and setting up sulfur dioxide emission mitigation measures in regional environmental planning processes, which currently have been implemented in some cities and counties in Korea.

  • The integrated supply chain of business partners for e-Commerce in cyber space is defined as Logistics Chain if the cooperative activities are logistics-related. Logistics Chain could be managed effectively and efficiently by cooperative technologies of logistics chain execution. In this paper, we propose a routing and scheduling algorithm based on the Tabu search by adding geographical information into existing constraint for pick-up and delivery process to minimize service time and cost in logistics chain. And, we also consider an uncertainty processing for the tracing of moving object to control pick-up and delivery vehicles based on GPS/GIS/ITS. Uncertainty processing is required to minimize amount of telecommunication and database on vehicles tracing. Finally, we describe the Logistics Chain Execution (LCE) system to perform plan and control activities for postal logistics chain. To evaluate practical effects of the routing and scheduling system, we perform a pretest for the performance of the tabu search algorithm. And then we compare our result with the result of the pick-up and delivery routing plan generated manually by postmen.

  • Slope failures during heavy rainfall have resulted in death of life and economic loss. In recent years, the research on slope damage assessment using Geographical Information System(GIS) has been actively carried out by researchers of several goverment organizations and schools. The researchers in Highway and Transportation Technology Institute (HTTI) of Korea Highway Corporation has developed the GIS database(DB), including highway, rainfalls, soil or rock geometry, types of damage, etc. and have been working on the damage assessment of highway slopes. The DB has been established and summarized in two different ways, such as highway routes and administrative districts. Grid of rainfall intensity generated by maximum rainfalls of each administrative district has been devloped. It shows good correlation of slope damage with heavy rainfalls. Most of damaged slopes were found in the amount of 100 mm to 300 mm rainfalls.

  • 유역에서의 수질관리를 수행함에 있어 비점오염원의 관리는 매우 중요하면서 복잡한 경우가 많다. 비점오염원의 관리에서 가장 우선시 되는 것은 토사 유출량의 관리이다. 이는 주로 농경지에서 유출되는 토사와 그에 흡착된 인(phosphorous)을 관리하는 것이다. 이 연구에서는 전라남도 화순군에 위치하고 주암호의 상류에 해당되는 외남천 유역의 유출량과 토사 유출량을 공간분포형 모델을 이용해 모의하였다. 또한 필터스트립의 저감 효과를 분석하기 위해 GIS(Geographic Information System) 데이터를 이용하여 필터스트립을 모의하고 공간분포형 모델의 특성을 이용하여 토사 유출량이 심각한 지역의 공간분포를 파악하고 필터스트립의 저감 효과를 시각적으로 나타내었다. 토사 유출량이 가장 심한 소유역에 필터스트립을 설치한 결과 유출수와 토사 유출량이 각각 17.2%와 46.4%가 감소되는 것으로 예측되었다.

  • MARPOL (Maritime Pollution Treaty) 부속서 (Annex VI) 경우 대기오염 규제 내용이며, 최근 선박 배기가스 배출규제 강화 목적 개정됨에 따라 관련 규정을 충족하기 위한 적극적인 조치가 요구된다. 예를 들어 Sulfur Dioxide (SOx, 황산화물) 경우 2020년 기준 전 세계 해역 내 운항하는 선박은 황 함유량 0.5% 기준의 배출 요구 기준을 충족해야 한다. 배출규제 해역 지정 시 해당 해역 선박 배기가스 배출량 계산 산정 기준 확립이 필요함에 따라 대기환경에 대한 종합적인 분석이 필수적으로 요구된다. 본 연구에서는 황산화물 배출량 산출 방법론으로써 그리드 셀 내 선박 점유시간을 계산한다. 점유시간이 길수록 선박 통항 및 배기가스 배출이 밀집되어 있음을 의미한다. 밀집도 분석에 더불어 선박의 특성이 반영된 시간당 배출량을 적용하여 배출 공간 인벤토리를 구축하였으며 분석 결과를 GIS (Geographical Information System) 환경에서 공간 지도로 시각화하였다. 기존 국내 황산화물 배출규제 해역의 효과 평가에 더불어 외항 범위까지 규제 확대 시나리오확립 후 비교 평가를 통하여 배출량 감소 효과를 정량적으로 확인하였다.

  • Seismic movements have varying effects on structures based on characteristics of local site. During an earthquake, weak soils are susceptible to damage due to amplified wave amplitudes. Soil-structure interaction issue has garnered increased attention in Türkiye, after devastating earthquakes in Kocaeli Gölcük (1999), Izmir (2020), Kahramanmaraş Pazarcık and Elbistan (2023). Consequently, liquefaction potential has been investigated in detail for different regions of Türkiye, mainly with available field test results. Çankırı, a city located close to North Anatolian Fault, is mainly built on alluvium, which is prone to liquefaction. However, no study on liquefaction hazard has been conducted thus far. In this study, groundwater level map, SPT map, and liquefaction risk map have been generated using Geographical Information System (GIS) for the Buğday Pazarı District of Çankırı province. Site investigations studies previously performed for 47 parcels (76 boreholes) were used within the scope of this study. The liquefaction assessment was conducted using Seed and Idriss's (1971) simplified method and the visualization of areas susceptible to liquefaction risk has been accomplished. The results of this study have been compared with the City Council's precautionary map which is currently in use. As a result of this study, it is recommended that minimum depth of boreholes in the region should be at least 30m and adequate number of laboratory tests particularly in liquefiable areas should be performed. Another important recommendation for the region is that detailed investigation should be performed by local authorities since findings of this study differ from currently used precautionary map.
