To develop efficient control program against Japanese pine sawyer (JPS). Monochamus alternatus Hope, laboratory bioassay using 7 insecticides, and the residual effects of fog-machine treatment and ultra-low-volume spray by helicopter of fenitrothion induced 100% mortality 4 days after exposure (DAE), and exposure for 4 minutes did that 2 DAE. Even the periods when they were alive, they did not feed on treated P. densiflora shoots. All the topical applications of the fenitrothion on elytra, head, mouth, tarsus, and ventral parts show 100% mortality. The residual effect of fog-machine treatment of fenitrothion was very effective against JPS adults. When the adults were inoculated on the treated shoots at the 1st day of treatment with 50,000 and 5,000 ppm solution of fenitrothion, the LT_(100) was only 1 day; even at the 11th day it was only 3 days. The residual efficacy of ultra-low-volume spray with helicopter lasted longer than that of fog-machine treatment. When the JPS adults were inoculated on the sprayed shoots even at the 10th day of the spray with 60,240, 5,000 and 1,000 ppm, the LT_(100) was only a day.

This study is to investigate the micro hydropower by discharge water of Jeju sewage treatment plant located in Jeju city and Dongbu sewage treatment plant located in Seogwipo city, Jejudo. The flow rate is applied at 1.11m³/sec in Jeju and 0.157m³/sec in Dongbu, which are the average 95 day flow rated for the recent 3 years. The net head is 5.21m in Jeju and 12.41m in Dongbu which are hight between discharge flow chamber and the location of hydraulic turbine installation. Therefore, the quantitiy of electric of power generation is estimated to be 42.97kW in Jeju and 14.6kW in Dongbu. The monthly quantity of electric generation is 28.23MW in Jeju and 9.46MW in Dongbu. Also the yearly quantity of electric generation is 338.7MW in Jeju and 113.53MW in Dongbu. The type of hydraulic turbine recommends a crossflow or a tubular in Jeju and an inline-type hydraulic turbine in Dongbu.
