시간 스케일러빌리티를 이용한 MPEG-4 FGS 비디오 부호화 기법
김종욱,이배호 전남대학교 전자통신기술연구소 2002 전자통신기술논문지 Vol.5 No.1
The paper shows MPEG-4 FGS(Fine Granularity Scalability) using the scalable video encoding technique that is adapted by MPEG-4 standard and a scheme to improve its efficiency. MPEG-4 FGS is the encoding technique that has the good flexibility for various property of devices and bandwidth variation over the internet. To improve MPEG-4 FGS coding efficiency, we applied an encoding technique with temporal scalability. In other words, the base layer is encoded with the same technique as the typical MPEG-4 FGS and the enhancement layer is encoded by adding temporal scalability property In test results, we could know that had better coding efficiency in the case of adding temporal scalability for the enhancement layer.
국내시유 중 Ascorbic Acid의 함량변화에 관한 연구
김종욱,윤여창 한국낙농학회 1986 韓國酪農學會誌 Vol.8 No.1
本 實驗은 市乳 貯藏中 UHT乳와 HTST乳, 包藏容器, 螢光 照射에 따른 asorbic acid의 含量變化를 調査한 實驗으로 結果를 要約하면 다음과 같다. 1. UHT乳의 ascorbic acid 含量은 HTST乳에 비해 21% 낮았다. 2. Ascorbic acid와 酸素含量은 10日 동안 貯藏中 조금씩 減少하였다. 3. 7日 동안 貯藏中에 jiro pack에 있어서 ascorbic acid와 酸素 減少率은 polyethylene pack과 carton pack에 있어서 보다 높았다. 그러나 tetra pack에 있어서 ascorbic acid와 酸素의 含量은 7日째부터 13日째의 貯藏期間中에 각각 15%씩 減少되었다. 4. 400 Lux 螢光에 노출된 투명한 유리병에 담긴 市乳의 ascorbic acid와 酸素含量은 24時間 貯藏中에 각각 88%와 24.7%로 급속히 減少되었다. This experiment was carried out to investigate the changes in the content of ascorbic acid in domestic market milks that was treated with UHT and HTST method, fluorescent light, and that filled different packaging containers during storage. 1. The content of ascorbic acid in UHT milk was 21% lower than that of ascorbic acid in HTST milk. 2. The content of ascorbic acid and oxygen decreased little by little during the 10 days of storage. 3. Decrease rate of ascorbic acid and oxygen in Jiro pack was higher than that of ascorbic acid and oxygen in Polyethylene pack and Carton pack during the 7 days of storage. However, the content of ascorbic acid and oxygen in Tetra pak decreased about 15% respectively from the 7th day to the 13th day. 4. The content of ascorbic acid and oxygen in clear glass bottles exposed to 400 Lux. fluorescent light decreased rapidly about 88% and 24.7% respectively during 24 hours.
포크너의 「헛간방화」 : 애브너 스놉스의"초라하지만 의식(儀式)적인 폭력행위"의 의미
김종욱 한국현대영미소설학회 2002 현대영미소설 Vol.9 No.1
This article is a study of the meaning of Abner's violence, 'barn burning', in the context of the southern history of the 1930s. It has been acknowledged that the regional history of the South provides a useful tool for understanding Faulkner's works, and this short story can be read as an example that shows the close relations between history and his literature; the contemporary social circumstances being one of the most efficient means of catching up with the work. This article focuses on the violent arsonic action of Abner Snopes, a sharecropper and a patriarch of a family. That is, though it appears that he is a furious and anti-social figure and eventually the cause of the psychological conflict of his innocent son, his violence can be seen as a desperate expression of the will to survival of a class which faces 'crisis' in the social and economical shift. Just as his habitual shabby fire made during their numerous movings is "ceremonial", his repeated arsons can be "ceremonial" and powerless protest against the society which doesn't allow the poor and weak to sustain humane life. And his desperateness is made 'extreme' because it is witnessed through the innocent eyes of his youngest son, Sarty, who is of all senses and instincts without any tool to understand the larger picture of the society surrounding him and his family. Trying to keep up with the social changes through a character, Abner Snopes, Faulkner senses the contradiction inherent in Southern history. In that sense, the work can be read as the text about the possibility of change in the American South.
