초기치에서 발생되어지는 비트의 소비를 저주파영역에서의 부호화하는 과정을 없애고, 각 대역별 임계값을 통해, 비 트정렬시 LIS에서 발생되어 질 수 있는 비트 소비를 줄일 수 있었다. 그리고 마지막 단계로 허프만 코딩을 적용하여 압축효율을 향상시켰다. 실험 결과를 통해, 특히 낮은 비트율에 대해서 비트율의 향상을 가져오게 되어 전송시에 있어 서 더욱 점진적이고 프로그레시브한 전송을 가능하게 되었다.

본 연구는 대구시의 4월 평균기온자료에 대해 간섭모형을 적용하여 온도변화의 양상이 어떠했는지를 분석하고 향후의 기온 변화를 예측해 보았다. 본 연구에서는 현재까지의 도시별 이산화탄소 배출량 변화를 정량적으로 추정하기 어려운 이유로 간섭의 시점을 시계열상에 나타난 시점으로 선정하였고 그 결과 간섭시점은 크게 1947년과 1970년인 것으로 나타나고 있다. 미래의 이산화탄소 배출량이 어떻게 변할 것인가에 따라 그 결과는 많이 달라지겠지만 만약 이산화탄소 배
