Researchers found that the teachers’ self-efficacy can help to promote the constructivist approaches of engaged teaching learning activities such as group works and better classroom management. However, few studies have focused particularly on examining science teachers’ self-efficacy on student engagement but not toward three dimensions of behavioral, cognitive and emotional engagement of learning. In this sense the major goal of this study was to develop a reliable, valid, and efficient...

방열장치가 간단해지거나 전력용량을 증가할 수 있게 되었으며 열발산이 곤란한 monolithic I.C.화에 유용하도록 하였다. A method on minimizing the power dissipation in the control element of a series D.C. voltage regutator is devised. An additional control circuit which reduces the average voltage drop across the control element according to increasing the load current is attached :o the trial phase controlled pre-regulator system. It is verified that the power dissipation in the control element is...

Porcine reproductive and respiratory syndrome virus (PRRSV) RNA load in sera and tissues during acute phase of infection was evaluated using a PCR- based quantitative assay. More than 80% of infected pigs (21/25) showed the peak level of viral RNA concentrations in serum (up to 8.6 x 10(8) copies/ml) at day 5 postinfection (PI), and started to clear the virus from the systemic circulation thereafter. Regression analysis using the viral RNA concentrations in sera obtained from days 5 to 14 PI...

Early warning services for crop diseases are valuable when they provide timely forecasts that farmers can utilize to inform their disease management decisions. In South Korea, collaborative disease controls that utilize unmanned aerial vehicles are commonly performed for most rice paddies. However, such controls could benefit from seasonal disease early warnings with a lead time of a few months. As a first step to establish a seasonal disease early warning service using seasonal climate...

simplified equilibrium model for enzymatic reactions was applied to obtain a temperature function for asymptote parameter (A) of logistic model. For the position (B) and the rate (k) parameters, a reciprocal model was used to calculate the respective temperature functions. The nonlinear logistic model described successfully the response of appressorium formation to the combined effects of temperature and wetness period. Especially the temperature function for asymptote parameter A reflected the...

Phosphorylation is a major post-translational modification of proteins that regulate diverse signal transduction pathways in eukaryotic cells. 14-3-3 proteins are regulatory proteins that bind to target proteins in a phosphorylation-dependent manner and have been shown to play an important role in plant growth and development, primary metabolism, and signal transduction. Because phosphorylation plays a critical role in signal transduction pathways to trigger plant immunity, involvement of 14-3-3...
