General Description of the Research Project	This scientific feasibility study aims to solve the social problem where only 16% of people in rural areas of the Kingdom of Cambodia can access to safe drinking water by utilizing the Japanese technology for improving the quality of water with UV-LEDs which have been developed in Nagoya University and Mie University. To solve this problem, major concern which hinders the UV-LEDs to be put into effect in society are their high price and low output power (mW/JPY). Therefore, Nagoya University and Mie University will develop fundamental technologies for realizing high-power UV-LEDs. At the same time, the study aims to identify the other problems in the region by conducting on-site verification projects in cooperation with LED manufacturers, and so forth. Furthermore, the study aims to identify local needs by conducting field surveys with local government agencies as well as manufacturers and agencies of the water sterilizers. The Royal University of Phnom Penh as the focal point, the governmental institutions, the water suppliers, and NPOs in Cambodia will cooperate with Nagoya University and Mie University. This study will clarify the solutions to solve the regional problems and the local needs pertain to the development of water sterilizers utilizing UV-LEDs in rural areas of Cambodia.
