This paper investigates the EEG waveform distortions caused by the transient responses of various types of signal conditioning filters, which are generally introduced for automated analysis of EEG. This study explicitly simulates the filter responses to the typical EEG waveform models, and compares the distortions. The filter distortion effects are also illustrated with the experiments on real EEG signals.

바이오 인포매틱스(bioinformatics) 분야 중 한 분야인 셀 기반 분석(cell-based assay) 시스템 구축의 필요성이 최근 대두되고 있다. 특정 시약 또는 시험 물질을 셀 세포에 투여했을 때 시간 축 변화에 따라 변화하는 세포의 변화를 감지하기 위해서 세포 영상의 영역 분할이 선행되어야 한다. 본 논문에서는 전체 영상에 대하여 셀 공통 영역을 추출하고, 추출된 공통영역을 스네이크(snake) 기법을 이용하여 세포 영역을 분할하는 방법을 제안하고자 한다.

As a society has developed, much concern has been put on appearances of people with development of economy. Accordingly malocclusion patients have been increasing. With this trend, it has become very important to investigate patients characteristics so as to cure the patients effectively. This study investigated 724 malocclusion patients who had been examined diagmosed and recorded well at Chong-a Dental Hospital for 5 years from 1994 to 1998. The results are as follows ; 1) The total number of orthodontic patients in 1998 increased about 79% than in 1994, and female orthodontic patients(68.1%) were more than male ones(31.9%). 2) Age distribution has shown more than 19 year-old group being the largest(48.9%) 3) Distributions in the types of malocclusion according to the Angle's classification have shown 42.5% for class I division, 21.5% for class II division, 35.9% for class III division, being class I division the largest. 4) 50.1% of the total patients were from Kang-nam Gu, So-cho Gu, and Song-pa Gu.

(Allyloxy)methyl-Crown Ethers have been used as metal cation carriers in a bulk liquid membrane system. Competitive transports by the AMDT18C6 and the AM18C6 are selective for Pd(Ⅱ) ion and Pb(Ⅱ) ion over other transition metal cations respectively. Studies of complexations of (Allyloxy)methyl-Crown Ethers with metal cations have been carried out by titration calorimetry and potentiometry.
