김종규 대불대학교 1996 論文集 Vol.2 No.1
Hyang-ga had not been made an artistic motive. Hyang-ga have a purpose to come true hopes. But a part of ancient legacy made from need of actual life has today a value as an aesthetic subject. It is that Hyang-ga have literary beauty as a lyric. Becouse Hyang-ga have an aesthetic as a literary production. The principal element of literary from lies at the way of expression and the most specific gravity of rthetorics to from expressions of a lyric is a metaphor. So this study considers the course how the metaphor of Hyang-ga should originate and develop.

We present a method that can recognize face images using independent component analysis that is used mainly for blind sources separation in signal processing. We assumed that a face image can be expressed as the sum of a set of statistically independent feature images, which was obtained by using independent component analysis. Face recognition was peformed by projecting the input image to the feature image space and then by comparing its projection components with those of stored reference images. We carried out face recognition experiments with a database that consists of various varied face images (total 400 varied facial images collected from 10 per person) and compared the performance of our method with that of the eigenface method based on principal component analysis. The presented method gave better results of recognition rate than the eigenface method did, and showed robustness to the random noise added in the input facial images. 신호처리 분야에서 미지의 신호원 분리에 주로 응용되는 독립 성분 분석법을 이용하여 얼굴인식을 할 수 있는 한 방식을 제안하였다. 하나의 얼굴영상 자체가 통계적으로 서로 독립인 어떤 미지의 특징영상의 합으로 표현될 수 있다고 가정하고 이 특징영상을 독립성분분석을 이용하여 구한 후, 새로운 얼굴이나 변화된 얼굴을 특징영상의 공간에 투영시켜 투영된 성분을 기준 얼굴영상과 비교하는 방법으로 인식을 수행하였다. 변화가 심한 여러 얼굴영상으로 구성된 데이터베이스(한 사람 당 10개씩의 변화된 400개의 얼굴 영상)에 대해 얼굴인식 실험을 수행하였고 또한 주성분 분석에 기초한 고유얼굴을 이용한 인식률과 비교 분석하였다. 제안된 방식은 주성분 분석법에 비해 높은 인식률을 제공하며, 특히 입력 얼굴 영상에 첨가되는 랜덤 잡음에 대단히 강한 특성을 갖는다.

Inadequate food handling and poor hand hygiene play a major role in the occurrence of foodborne diseases. The objective of this study was to find out if the level of microbial contamination on the hands of food preparers varies by time during their working period. This study focused on the contamination of aerobic plate count,total and fecal coliforms, Escherichia coli, Staphylococcus aureus, and Salmonella spp. Sampling from left hand and right hand of twenty food preparers was done with glove-juice method at every two hours during their work. Microbiological testing was conducted according to the Food Code of Korea. The microbiological load on the hands was changed over time. Samples taken from their hands before work and at 8 hours showed higher levels of bacteria than those taken at 2, 4, and 6 hours during work and/or after work (p < 0.05). The contamination levels of microorganisms were consistently higher in right hand than in left hand. Poor hand hygiene practices were indicated by the positive results for total and fecal coliforms, E. coli, S. aureus, and Salmonella spp. on the hands of some food preparers. This study indicates food preparers' hands can be a vehicle of pathogen during their work. The results of this study emphasize the importance of hand hygiene education and training targeting the food preparers.
