Abstract: Today when the amount of waste increases and its fractions vary, establishing the integrated waste management system based on recycling, reuse and re-circulation technologies in terms of stabilization, minimization and recycling of waste is a crucial issue to properly solve in the environmental protection in the case study city (Pyongyang), as urban poplluation, production and consumption increase. Therefore this paper conducted the analysis for the amount of waste generation per fraction, its trend and treatment in the case study city, which is one of the primary issue to rationally improve solid waste management and successfully perform strategic waste management planning. Based on the analysis for disposals of solid waste generated in the case city, 50.2% of total amount of waste is recycled and reused, 0.3% is incinerated and 49.5% is landfilled. Percentage of recycling and reuse of industrial waste is high with 76.3%, but for household waste is low with 26.5%.

Abstract: Urban sprawl or sprawl is phenomenon attached to urbanization, which increases corresponding to the speed of urbanization. Sprawl happens when city central facilities become overloaded and even stronger if there is implementation of the policy of decentralized development from urban planners and government. Ho Chi Minh city central facilities is overloaded because of high density of population, which is the reason Ho Chi Minh city government implements decentralized development policies and decentralized urban planning project. Even through, there are lots of decentralized urban planning and support policies but there is still lack of research about urban sprawl, especially about transportation network of sprawling area like Phuoc Kien Commune. Applying research, scientific observation and analysis, summary methods, this research main purpose is pointing out the change of transportation of Phuoc Kien Commune, which is the most affected by Ho Chi Minh city urbanization and urban sprawl. Moreover, this research is the framework research for further research about transportation network transition affected by urban sprawl and urbanization in future.

Abstract: Landslide hazard maps are important for risk management and land-use planning in mountainous countries such as Korea. The aim of this study was to produce and evaluate a shallow landslide hazard map using a physically based slope stability model coupling with hydrological models in Mt Umyeon, South Korea. The incorporation of a rainfall frequency–duration relationship of heavy rainfall into the assessment of landslide hazard provides a practical way to include climate information into the estimation of shallow landslide hazard. A GIS-based landslide inventory map of 146 landslide locations was prepared using data from previous reports, aerial photographic interpretation, and extensive field work. And this landslide inventory was used to document sites of instability and to provide a test of model performance by comparing observed landslide locations with model predictions. A combined approach of Quasi-dynamic wetness (QDWI) and infinite slope model was used to prepare landslide hazard maps of different durations i.e. considering 17hr duration with average rainfall intensity (case I), 15hr duration with average rainfall intensity (case II) and the last 2hr duration and average intensity added in case II (case III). The results of the analysis were verified using the landslide location data. Receiver operating curve was used to compare all cases. The case III shows satisfactory agreement between hazard map and the existing data on landslide locations with 82.2% accuracy of the model. The results of this study can therefore be used to mitigate landslide-induced hazards and to plan land-use.
