본 논문에서는 주어진 상세배치의 배선밀집도를 예측하고, 배선밀집도가 높은 지역을 효과적으로 해결하는 새로운 알고리즘을 소개한다. 제안된 기법의 특징은 다음과 같다. 첫째, 특정지역을 관통하는 넷이 많아 그 지역의 배선밀집도가 높을 경우 관통하는 넷에 연결된 셀들을 효과적으로 찾아내어 그들의 위치를 조정함으로써 배선밀집도를 완화시킨다. 둘째, 리플이동 (ripple movement) 기법을 이용하여 셀들을 이동함으로써 배선길이를 희생시키지 않으면서 배선밀집도를 완화시킨다. 셋째, 셀의 이동에 따른 배선밀집도의 변화 및 배선길이의 변화를 효과적으로 추적할 수 있도록 증분 자료구조 (incremental data structure)를 사용하였기 때문에 실시간으로 변화되는 상황에 적합한 셀 선택이 이루어지며, 실행시간도 매우 빠른 장점이 있다. 마지막으로, 본 논문에서는 MST 넷 모델을 사용하여 배선밀집도를 예측하지만 제안한 기법은 특정 넷 모델에 상관없이 적용할 수 있다. 특히 실제 라우터로부터 배선정보를 얻을 수 있다면, 배선밀집도는 더욱 효과적으로 해결될 수 있다. 제안된 기법을 이용한 실험결과는 배선길이를 희생하지 않으면서 배선밀집도를 매우 효과적으로 개선할 수 있음을 보여준다. This paper describes a new effective algorithm to estimate routing congestion and to resolve highly congested regions for a given detailed placement. The major features of the proposed technique can be summarized as follows. Firstly, if there are congested regions due to some nets which pass through the regions it can determine which cells affect those congested spots seriously and moves some of them to resolve congestion effectively. Secondly, since the proposed technique uses the ripple movement technique to move cells it resolves congestion without sacrificing wire length. Thirdly, we use an efficient incremental data structure to trace the changes in congestion and wire length as cells move. Hence, selection of cells to move could be very accurate and fast in the course of iteration. Finally, although an MST net model is used to resolve congestion in this paper, proposed technique can be work with any net model. Particularly, if proposed technique can obtain routing information from a real router, congestion can be resolved more effectively. Experimental results show that the proposed technique can resolve congestion effectively and efficiently without sacrificing wire length.

다종 위성 자료를 활용한 해수면온도(SST) 합성기법 개발 연구

오은경,양찬수,Oh, Eun-Kyung,Yang, Chan-Su 해양환경안전학회 2011 海洋環境安全學會誌 Vol.17 No.3

본 연구는 다종 위성 자료를 활용한 해수면온도 합성 기법에 대한 연구이다. 현재 많은 연구자들이 사용하고 있는 NGSST 알고리듬은 위성에 따른 정확도를 고려하지 않고 시 공간 상관도만을 계산하여 해당 픽셀의 값을 추정한다. 본 연구에서는 위성 센서별로 가지고 있는 정확도를 추가로 고려한 해수면온도 합성기법을 제안하고 기존 알고리듬과의 비교를 수행하였다. 합성장을 산출하는데 사용된 센서는 적외 센서인 MODIS, AVHRR 그리고 마이크로파 센서인 AMSR-E를 사용하였고, 2011년 4월 4일을 기준으로 5 km의 공간해상도를 갖는 일일 해수면 온도 합성장을 비교하였다. 부이와의 비교 결과, 기존 방법(NGSST Method)과 제안 방법(New Method)에 의한 표준편차는 각각 $0.15^{\circ}C$와 $0.12^{\circ}C$이었다. 또한 기존 방법보다 제안 방법에 의한 해수면온도 값은 연안을 제외한 대부분의 해역에서 다소 높게 산출이 되었다. 현 단계에서 정량적인 평가는 어렵지만, 본 연구를 통하여 해수면온도 합성기법에 대한 연구 방향이 제시되었다고 판단된다. This study introduces a technique to merge three different sea surface temperature(SST) data obtained from multi-satellite sensors. NGSST algorithm, the most popular method of related society, estimates a center pixel of target SST using temporal and spatial correlations, excluding SST accuracies according to sensing methods or properties of satellites. We suggest a merging method of SST to consider the accuracy by satellite or sensor with a comparison with NGSST method. The data used for a merged daily SST with spatial resolution of 5 km was applied from three different satellite sensors such as MODIS, AVHRR and AMSR-E from April 2 to 4, 2011 around the southern coast of Korea. Results of the comparisons showed that the new method is higher than the NGSST method and its STDEV represents a comparatively low value. In future we are planning to compare and analyze the datasets during the daytime as well as nighttime over total cycle of the day.

In coastal areas that are affected by continuous, seasonal or occasional pollution sources, bivalves accumulate biological contaminants such as pathogenic bacteria. We investigated the effect of natural seawater relaying and electrolyzed seawater depuration on the bacteriological quality of artificially contaminated oysters Crassostrea gigas and short-necked clams Ruditapes philippinarum to suggest an alternative method of shellfish sanitation control.When artificially contaminated oysters and short-necked clams (fecal coliform level 1,700 MPN/100 g) were relayed into a sea area of safe bacteriological water quality, the fecal coliform level dropped to below 110 MPN/100 g after 1 day. The bacteriological quality of oysters and short-necked clams that are contaminated at a fecal coliform level of 1,700 MPN/100 g could be improved, and become appropriate for raw consumption by a single day relay under proper environmental conditions. When artificially contaminated oysters (fecal coliform level 330 MPN/100 g) were depurated with electrolyzed seawater, 94% of fecal coliform was eliminated after 12 h and fecal coliform was undetectable after 24 h. After 24 h depuration with electrolyzed seawater, the fecal coliform level of short-necked clams with initial fecal coliform of 2,400 MPN/100 g was below 20 MPN/100 g. However, the fecal coliform level of short-necked clams with initial fecal coliform of 17,000 MPN/100 g was relatively high, at 790 MPN/100 g, even after 24 h of depuration with electrolyzed seawater, because of the repeated cycle of excretion and accumulation of fecal coliform in shellfish tissue under the closed depuration environment. Such natural seawater relaying and electrolyzed seawater depuration can be restrictively applied to improve or secure the bacteriological quality of oysters and short-necked clams in accordance with safety levels for bivalves for raw consumption.

The purpose of this study is to measure the effect of group art therapy program in improving child``s emotional quotient in the poor family. The design of this study is pretest-post test control group design. The independent variable was group art therapy and the dependent variable was emotional quotient. The subjects was 12 persons of 4 grade to 6 grade of elementary school students from M-Gong bu bang in Daejeon. Among subjects, 6 persons were placed in the experimental group and 6 persons in the control group which doesn``t participate in group art therapy. To perform this study the group art therapy program is carried out 1~2 session for a week and the whole sessions are 15. Each session being allocated 60 minutes. The instrument of measurement used in this study is EQ-test and KHTP test and the program of group art therapies that the presenter of this thesis developed. M(mean), SD(standard deviation) to analyze data collected by EQ test. Sub-areas of each measurement have 5 areas, which are : perception of emotion, expression of emotion, empathy, regulation of emotion and utilization of emotion. The conclusions of this study were as follows: The experimental group``s emotional quotient was significantly increased than the control group did after the group art therapy sessions. The levels of perception of emotion was statistically significant between the pre-test and post-test. From these conclusions, it is suggested that group art therapy has positive effect in child``s emotional quotient in the poor family.

야샤르 케말의 「빈보아신화(Binboga Efsanesi)」에 나타난 노마디즘 연구

오은경 ( Eun Kyung Oh ) 한국외국어대학교 중동연구소 2008 중동연구 Vol.27 No.2

In this article, we review the nomadism of Turkish writer Yasar Kemal through his novel, "Binboga Efsanesi". Namely that nomadism is not a way which looks only for central and transcendental values. It is a way to live with creation by asking things of life. This is the exact way to be a nomadic subject. Also, it is something possible to achieve through behavior, by "becoming". Yasar Kemal shows how the desire of the Turkmen nomads for deterritorialization was frustrated by a national apparatus. The deterritorialized desire of the nomads to escape from the nation or possessiveness clashes against a lifestyle of possessions and accumulated wealth. In his novel Kemal explains his nomadism by showing the conflicts between nomadic people and the nation. At a same time he represents the others, he speaks in the name of nomads who were excluded and oppressed in the modern period. This trial of his is a slice of the politics of formation. This novel shows that the creativity and voluntary expression of life as a nomadic subject will endure in spite of the national apparatus, and that deterritorialization can be a form of formation which will continue forever.
