This study was carried out to analyze the disparities of basic living infrastructure between Guns(rural counties), and between Eups/Myuns(rural districts) in Jeollanam-do province. For the purpose of this study, dimensions of regional disparity in basic living structure were measured by 3 components ; road, public water service and sewage disposal. By utilizing the published statistics, this study has examined 8 Guns(counties) containing Eup and Myon in Jeollanam-do province which can represent 4 different rural areal types, respectively, i,e. mountainous, semi-mountainous, flat and seashore areas. The data acquisition time of this study is fixed on end of 2009 year in order for possible collections of the most recent published statistics. It presents evidence on the magnitude and evolution of discussion of regional disparities between Guns(counties), and between Eup & Myon, and between Myons in Jeollanam-do province even though infrastructure provision level of Jeollanam-do rural areas are much more improved than the past. Concludingly, the existing disparities in this area is meaningful and so, it should be seriously reconsidered when deciding local government's budget allocation priority.

This study compared the differences between the Dendranthema boreale and Dendranthema indicum in their habitat, soil adaptability, species composition and community structure in Korea. More D. boreale distributed than D. indicum to in the place where high elevation and on the surface of low degree slope. Both D. boreale and D. indicum growed well in south-east direction of the slope. The soil pH of D. boreale and D. indicum was 6.1 and 7.1, respectively. Ca, Mg, Na and organic matter content of the soil of D. boreale habitat was significantly lower than that of the D. indicum habitat. There were 102 and 88 taxa, in D. boreale and D. indicum habitat, respectively. Both species generally distributed along with herbs than along with trees. The important species found in D. boreale habitat were Artemisia princeps (57.1%) and Humulus japonicus (33.3%), and the D. indicum habitat were Miscanthus sinensis (42.9%) and Lonicera japonica (38.1%). The D. boreale group was classified into Artemisia princeps, Crepidiastrum denticulatum, Miscanthus sinensis, Humulus japonicus, Pueraria lobata, Lespedeza bicolor, Lonicera japonica and Rubus crataegifolius community. The D. indicum group was classified into Artemisia capillaris, Peucedanum japonicum, Boehmeria pannosa, Pinus thunbergii, Lonicera japonica, Quercus acutissima and Robinia pseudoacacia community. There is a large difference bewteen D. boreale and D. indicum in their habitat, soil adaptability, species composition and community structure.

This text was analyzed and investigated the vegetation and floristic composition by cluster analysis and classification of phytosociological method, to evaluate the species composition, habitat environment and community structure of Liriope platyphylla and Liriope spicata group in Korea. The southeast slope gradient of the habitat of L. platyphylla and L. spicata was 6.7 to 8.4%, and the habitat altitude of L. platyphylla (41.0 m), L. spicata (114.9 m) was different. Habitat distribution of L. spicata was broader than L. platyphylla. Appearing plants of L. platyphylla and L. spicata group was 58 taxa, 99 taxa, respectively, and Coverage of tree layer was 87.5%, 92.5% respectively. In genus Liriope group, the highest appearing frequency of plant grow in the moist valley as Quercus serrata. Thus, plants of genus Liriope growth was better in moist shade. The vegetation of L. platyphylla group was classified into Quercus serrata community, Castanopsis sieboldii community, Pinus densiflora community and Pinus thunbergii community, and the Liriope spicata group was classified into Quercus serrata community, Quercus alien community, Quercus acutissima community, Prunus verecunda community, Robinia pseudoacacia community, Pinus densiflora community and Pinus thunbergii community. In genus Liriope group, Quercus serrata and Pinus densiflora communities was the closest the similarities.

웹캠은 영상 데이터의 전송시간을 줄이기 위해 메모리 정렬은 고려하지 않는다. 메모리 정렬이 되지 않은 영상 데이터는 GPU에서 처리하기 부적합하며 고속의 영상처리를 위해서는 GPU에서 메모리 최적화가 가능한 색상 형식으로 변환되어야 한다. 본 논문은 웹캠 영상의 색상 형식 변환을 NVIDIA CUDA를 이용하여 가속하는 최적화 기법을 제안한다. 메모리 접근과 쓰레드 구성에 대한 최적화를 진행하였고, 제안하는 구조의 성능 측정과 최적화 정도를 분석하기 위해 GPU 메모리와 연산의 성능을 제한하여 실험하였다. 그 결과 최적화 방법에 따라 최대 68% 이상 성능이 향상됐다.

This study was undertaken to develop a technique of discrimination using SSR makers in boxthorn cultivars.Forty one boxthorn cultivars, which were collected from Korea and China, were evaluated by 10 SSR markers. Total of 61alleles were detected, ranging from 3 to 13 with an average of 6.1 alleles per locus. The averages of gene diversity and PICvalues were 0.482 and 0.428, with a range from 0.25 (GB-LCM-022 and GB-LCM-087) to 0.83 (GB-LCM-167) and from0.24 (GB-LCM-022 and GB-LCM-087) to 0.81 (GB-LCM-167), respectively. Five markers out of 10 markers, GB-LCM-022, GB-LCM-075, GB-LCM-104, GB-LCM-167 and GB-LCM-217, were selected as key markers for discrimination inboxthorn cultivars. All of boxthorn cultivars were individually distinguished by the combination of five SSR markers.

텍스처 매핑(texture mapping)은 실감 있는 영상을 만들기 위해 3차원 그래픽스 칩에서 사용되는 기술이다. 이 방식 중 이중선형 필터링 모드(bilinear filtering mode)에서는 1개의 픽셀(pixel)을 처리하기 위해 4개의 텍셀(texture element: texel)에 접근이 요구된다. 본 논문에서는 텍스처의 접근패턴을 분석하여 동시에 4개의 텍셀을 접근할 수 있는 고성능 텍스처 캐시의 구조를 제시하였다. 3차원 게임인 퀘이크3(Quake 3)와 언리얼 토너먼트 2004(Unreal Tournament 2004)의 텍스처 접근 추출파일을 이용한 시뮬레이션 결과로 성능평가를 하였으며, 제시한 텍스처 캐시의 구조는 물리적인 크기가 8KBytes 이하인 경우 콜은 성능을 갖게 됨을 분석하였다.
