This study analyzes interrelationship with air pollution quality and land use patterns using GIS. The relationship can be obtained via three steps: (1) making out air pollution map from air pollution information of study area, (2) dividing land use patterns into residential area, commercial area, industrial area, traffic concentrated area, and non-polluted area, and (3) spatial overlaying analysis of GIS. Moreover, through analyzing air pollution quality by land use patterns, pollution sources can be identified. The results also coincide with the characteristics of conventional air pollution finding. More detailed analyses using articulated on site air pollution quality measurement databases are needed to correctly identify the pollution sources through finding interrelationship with land use patterns and air pollution Quality using GIS. The developed method can help trace the path of pollution sources and plan urban land use projects.

It can be important framework data to monitor the change of land-use pattern of river boundary in design and management of river. This study analyzed the change of land-use pattern of Gab- and Yudeung River using time-series aerial images. To do this, we carried out radiation and geometric correction of image, and estimated land-use changes in inland and floodplain. As the analysis of inland, the ratio of residential, commercial, industrial, educational and public area, that is urbanized element, increases, but that of agricultural area shows a decline on the basis of 1990. Also, Minimum Distance Method, which is a kind of supervised classification method, is applied to extract water-body and sand bar layer in floodplain. As the analysis of land-use, the ratio of level-upped riverside land and water-body increases, but that of sand bar decreases. These time-series land use information can be important decision making data to evaluate the urbanization of river boundary, and especially it gives us goodness in river development project such as the composition of ecological habitat.

The purpose of this study was to carry out land use suitability analysis of Seoul Metropolitan City based on ecopolis planning concept or environmentally sound and sustainable development. Objectives of the analyses were to save energy by increasing urban density and allocating urban land use types near to public transportation system, to increase food producing capacity by restoring fertile agricultural lands, and to enhance urban ecosystem by expanding and networking parks and green spaces. This study has two phases. First, the land use suitability analyses for commercial, industrial, residential, agricultural, and green spaces were carried out. Second, required urban land use .types were allocated based on ESSD concept. Two alternative land use plans were developed based on two population sizes:existing population of 11million and 4.4million derived by the application of ermergy theory of T. Odum.

Multi-temporal approaches using sequential data acquired over multiple years are essential for satisfactory discrimination between many land-cover classes whose signatures exhibit seasonal trends. At any particular time, the response of several classes may be indistinguishable. A harmonic model that can represent seasonal variability is characterized by four components: mean level, frequency, phase and amplitude. The trigonometric components of the harmonic function inherently contain temporal information about changes in land-cover characteristics. Using the estimates which are obtained from sequential images through spectral analysis, seasonal periodicity can be incorporates into multi-temporal classification. The Normalized Difference Vegetation Index (NDVI) was computed for one week composites of the Advanced Very High Resolution Radiometer (AVHRR) imagery over the Korean peninsula for 1996 ～ 2000 using a dynamic technique. Land-cover types were then classified both with the estimated harmonic components using an unsupervised classification approach based on a hierarchical clustering algorithm. The results of the classification using the harmonic components show that the new approach is potentially very effective for identifying land-cover types by the analysis of its multi-temporal behavior.

Despite the longing for democracy of most people, Myanmar has missed opportunities for social and economic development by military dictatorship. However, since 2010, the civilian government has gained new opportunities for reform. After turning to economic reform, developed countries such as the US and EU lifted the economic sanctions that they had taken in the past. As a result, it is growing rapidly compared to neighboring countries due to attracting foreign capital, tariff benefits on export items, and expansion of industrial infrastructure. Despite the increased investment value due to economic growth and democratization, the complex and customary land system of Myanmar must be an uneasy factor in securing stable land rights when entering overseas markets. Therefore, this study sought the method of securing the land rights in the development project through the analysis of the foreign investment system in Myanmar and the investigation of joint development cases. The results of this study are as follows. First, the acquisition of land use rights at the early stage of development can be considered through the foreign investment system. Under the Foreign Investment Law and Myanmar Investment Law, the land can be used for up to 70 years, and Under the Special Economic Zone Law, the land can be used for up to 75 years. Second, in relation to land compensation, it is required to establish a detailed resettlement plan for the indigenous people as the difficulty of land acquisition is expected due to the recent democratization trend and strengthening the voice of residents. Third, land use at the operational stage can be achieved by leasing the land from developers, and this will be the most realistic plan at present. In other words, the developer can directly develop the land created under the Foreign Investment Law and the Special Economic Zone Law, or Sub-lease and transfer the land use right to a third party.

Soil moisture is significantly related to crop growth and plays an important role in irrigation management. To predict soil moisture, various process-based model has been developed and used in the world. Various models (Land surface model) may have different performance depending on the model parameters and structures that causes the different model output for the same modeling condition. In this study, the three land surface models (Noah Land Surface Model, Soil Water Atmosphere Plant, Community Land Model) were used to compare the model performance (soil moisture prediction) and develop the multi-model simulation. At first, the genetic algorithm was used to estimate the optimal soil parameters for each model, and the parameters were used to predict soil moisture in the study area. Then, we used the multi-model approach based on Bayesian model averaging (BMA). The results derived from this approach showed a better match to the measurements than the results from the original single land surface model. In addition, identifying the strengths and weaknesses of the single model and utilizing multi-model methods can help to increase the accuracy of soil moisture prediction.

Ba Ria - Vung Tau province in Southern Vietnam is one of the fastest economic growing areas in the country, characterized by the rapid port and industrial development along the Thi Vai river. The socio-economic situation of the area has generally been improved; however, its part of the local inhabitants has not gained benefits from the changes. 35 surface water samples and 25 sediment samples were analysed with the interpretation of the SPOT images for 1995 and 2005. The data showed that rapid port and industrial development have resulted in significant losses of mangroves and agriculture land. The surface water was seriously polluted, particularly in terms of organic materials and suspended solids. It contained high and increasing oil concentrations. The river sediment was saline and slightly alkaline. It was heavily reduced, organic-rich, and contaminated with oil and heavy metals (Cu, Pb, and Cr).
