This study proposed uttering differences of adverbs according to the adverb placement among acoustic parameters, such as vowel duration, intensity, and F0 produced by 26 Korean speakers and 20 American speakers. This study mainly suggested four interesting findings: First, the duration and intensity of the vowels were strengthened when following the adverb to verb than following the adverb to nouns in both groups. Second, the vowel duration of adverbs in the final position of sentences was longer than in other types in both groups. Third, F0 of the vowel was strengthened when following the adverb of verbs than following the adverb of nouns produced by Korean speakers while American speakers relied more on the duration and intensity of vowels. Lastly, the closer the bond between the adverb and the verb, the more inverse the degree of reinforcement in the duration and intensity of the vowel.

In this paper, several methods for image reconstruction were investigated, such as simple back-projection method, inverse radon method and filtered back projection method, which would be effectively applicable to reconstruct the images from SPECT(Single Photon Emission Computed Tomography). Also, the optimum low-pass filter for filtered back-projection method was designed through the variation of cut-off frequency in Hamming filter. The experimental results involved followings: 1) the effective removal of the star effect and the noise in reconstructed images by using the designed filters. 2) the satisfactory images reconstructed by the filtered back-projection scheme. 3) the difference between expected cut-off frequency by simulation and chosen one by subjective evaluation with most meaningful diagnostics. It was shown that the optimal cut-off frequency should be not consistent in all images but varied according to the condition of projection such as SNR(signal to noise ratio) and operation factors determining radioisotope dosage, radio-pharmaceuticals, acquisition collection time.

본 연구는 담수직파재배 중 무논골뿌림재배의 재배기술향상을 목적으로 연구 하였던 바 구체적인 연구대상으로 조생종, 중생종, 주만생종의 3가지 품종을 잡초방제 등을 시험, 고찰한 결과를 요약하면 다음과 같다. 1. 종자의 까락은 입모율에 장해가 되므로 파종시 반드시 제거시켜야만 임모율의 향상을 꾀할 수 있다. 2. 증수를 위해서는 파종량을 10a당 3-5kg으로 파종하는 것이 적당하다. 3. 골의 깊이에 따라서 도복과 수량에 영향을 미치므로 골의 깊이를 2-4cm 정도로 한다. 4. 파종 후 초기에 담수가 중요하며 너무 깊은 담수는 종자를 한쪽으로 몰리게 하여 출아에 영향을 미치므로 얕게 담수하고 중간낙수는 2-3회 반드시 실시하여 벼의 활착을 높인다. 5. 시비량이 너무 많을 경우 도복이 증가함으로 표준시비량을 시비하고 질소는 기비 40%, 5엽기 30%, 유수형성기 30%로 분시한다. 6. 제초제는 노난매를 파종 후 40일에 300g을 체계 처리하여 방제효과를 높이고 잔존량이 많으면 증기제초제를 처리한다.
