Ⅰ. 개요
1980년대 이후의 인지심리학 내의 언어심리학에서도 Chomsky 언어학의 개념, 관점, 강조점들의 일부는 계속 살아 있다.
심적 구조와 규칙 및 창조적 생산성의 개념들은 인지심리학에서 언어뿐만 아니라 인지 전반의 특성으로서 수용되고 있다. 언어능력과 수행의 구분도 암묵적으로 인정되고
Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma

This research has conducted to analyze the main reasons that affected the high rate of suicide in Korea. It firstly was assumed to be affected by the remarkable economic growth in Korea which led the Korea to the 11th economic power country in the world. However, as a result of the regression analysis, the rapid economic growth was not the principal reason of the increase in suicide

(57) Abstract: PURPOSE: A safety device for pedestrians walking on a pedestrian crossing is provided to provide safety to pedestrians by automatically opening the pedestrian crossing during walking signal and by blocking the pedestrian crossing during stop signal to prevent the pedestrians illegal crossing. CONSTITUTION: A safety device for pedestrians walking
AbstractThe main topic of our project is to design a personal transportation that better accommodates the environment. Since Korean mothers are experiencing difficulties with using baby transportation in metropolitan areas, our team resolved to construct a baby stroller that is compatible with the Korean mass transportation system. Our final concept is composed of a stroller that single-hande
the growth of a particular crystallographic direction. Among the shapes whi- ch can be obtained, rod-like gold nanostructures have been observer or synthesized using various chemical approaches. In this paper, we report the successful aspect ratio control of gold nanorods by the seed-mediated method, along with an improvement in the yield. Two major parameters were controlled to optimize the grow
In this project, solutions to second order linear recurrence equations with constant coeffi- cients have been investigated. We have used generating functions to derive the general solution to the homogeneous equation and we show that in general the particular solution is complicated to find. By limiting the right hand side (RHS) in the equation to a polynomial-exponential family of functions we c

⑴ What is biofilter?
- Technology processed gas pollutants by biological methods, immobilized on porous carrier by the metabolic activity of microorganisms decompose into harmless substances
- Depending on the configuration and operation of the device, it can classify as Biofilter, Biological Trikling Filter, Bioscrubber and Air Lift Bioreactor
Example of use of Biof
as follows. Insertion loss at 2.25 GHz is 2.28 dB. Insertion loss at 2.75 GHz is 2.33 dB. Attenuation at 2 GHz is 32.75 dB. Attenuation at 2.5 GHz is 44.35 dB. Attenuation at 4 GHJz is 50.74 dB. And the number of ripple in passband in 4. Except for attenuation in passband, the other results are satisfied with required specifications. Attenuation in passband of required specifications is 0.5 dB
