  • There is an increasing emphasis on science teaching in inclusion education setting, but still few research and practice in science education field including science teacher training course as well. It is well known that teaching efficacy of teacher is an important factor to influence teaching behavior and students' learning, but it is hard to find related studies about self-efficacy on teaching science for the disabled students. In this study pre-service science teachers' self-efficacy on science teaching for the disabled students was investigated and analyzed. For this a questionnaire consisted of 3 sub-scale like learning efficacy scale, teaching efficacy scale, and outcome expectancy scale was enacted to 97 pre-service science teachers. As a result, pre-service science teachers showed relatively low efficacy in teaching but showed positive learning efficacy and outcome expectancy. There was no meaningful difference in distribution of efficacy belief by gender, however the experience of teaching science for the disabled students made difference in outcome expectancy. From this study the implication for science teacher training course was inferred to meet the needs for science education in inclusion setting.

  • This study was conducted to determine Seasonal Occurrence, soybean damage and control efficacy of bean bug, Riptortus clavatus Thunberg at soybean field in Honam province. Occurrence of R. clavatus varied at seeding times with annual difference. The peak occurrence of R. clavatus was appeared at late of August for late May seeding and middle of September for middle June seeding. There was difference in the peak occurrence of R. clavatus due to different growing stages affected by different weather conditions though soybean was seeded at same time. If the rate of soybean seed damage area by R. clavatus sucking increases, the germinating rate was greatly decreased. If the rate of soybean seed damage area is above 50 percent, in particular, the germinating rate was very low with 2 percent. Control efficacy against R. clavatus was the highest with $91\%$ at 3 times treatment of insecticide at $R_4$ (full pod stage) + $R_5$ (Beginning seed stage) +$R_6$ (full seed stage) of soybean growing stages in field.

  • This paper presents an active position control of a single-rod cylinder system featuring an electrorheological(ER) fluid-based valve. The ER fluid consisting of silicone oil and chemically treated particles is firstly composed and its Bingham property is tested as a function of imposed electric field. A multi-channel plate type of ER valve is then designed and manufactured on the basis of the field-dependent Bingham model. Performance test of the ER valve is undertaken by evaluating pressure drop with respect to the number of electrode as well as the intensity of the electric field. Subsequently, the ER valve-cylinder system is constructed and its governing equation of motion is derived. A neural control scheme for position control of the cylinder is formulated by incorporating proportional-plus-derivative(PD) controller and implemented. Experimental results of both regulating and tracking control responses are presented in order to demonstrate the efficacy of the proposed ER valve-cylinder control system.

  • In case of field weakening region torque is directly affected by flux. In this region the flux reference is decreased inversely proportional to the rotor speed. As the flux is decreased the magnetizing inductance is normally increased. The increased magnetizing inductance limited voltage for controlling current. In this paper, measuring q axis voltage in field weakening region magnetizing inductance in flux calculating can be readjusted. Computer simulation and experiment results demonstrate the efficacy of the proposed method. Proposed algorithm is expected to the application of the adjustable drive system in the spinning and weaving field.
