최근 UCC를 중심으로 동영상 데이터에 대해 사람들의 관심이 증가하고 있다. 따라서 동영상 데이터의 내용-기반 검색을 지원하는 효율적인 색인 기법이 요구된다. 그러나 Hybrid Spill-Tree를 제외한 대부분의 색인 기법들은 대용량의 고차원 데이터를 다루는데 비효율적이다. 본 논문에서는 동영상 데이터의 내용-기반 검색을 지원하기 위한 효율적인 고차원 색인 기법을 제안한다. 제안하는 고차원 색인 기법은 기존 Hybrid Spill-Tree을 기반으로 새롭게 제안하는 클러스터링 방법과 시그니쳐를 이용한 데이터 저장 방법을 결합하여...

클러스터링은 유사한 데이터 포인트들을 그룹으로 묶어 데이터를 분석하는데 유용하다. 본 논문에서는 기존의 K-means 알고리즘과 비교해 고차원 대규모 데이터에 대해서 효율적으로 동작하는 K-means 알고리즘을 제안한다. 제안된 알고리즘들은 점간 거리 정보와 휴면 군집을 이용해 불필요한 거리계산을 줄인다. 제안된 알고리즘은 기존의 연구의 제안된 알고리즘에 비해 공간을 적게 쓰면서 동시에 빠르다. 실제 고차원 데이터 실험을 통해서 제안된 알고리즘의 효율성을 보였다.

This study was conducted to measure the difference in levels of cerebral metabolites in the right and left hemispheres, gray (GM) and white matter (WM), imaging planes, and anatomical regions of healthy dogs to establish normal variations. Eight male Beagle dogs (1 to 4 years of age; mean age, 2 years) with no evidence of neurologic disease were studied. Using the multi-voxel technique on a 1.5 Tesla magnetic resonance imaging scanner, metabolite values (N-acetyl aspartate [NAA], choline [Cho],...

Virus-like particles (VLPs) composed of the truncated capsid protein of swine hepatitis E virus (HEV) were developed and immune responses of mice immunized with the VLPs were evaluated. IgG titers specific for the capsid protein of swine HEV were significantly higher for all groups of mice immunized with the VLPs than those of the negative control mice. Splenocytes from mice immunized with the VLPs also produced significantly greater quantities of interferon (IFN)-γ than interleukin (IL)-4 and...

The present study was undertaken to evaluate porous hydroxyapatite (HAp), the powder of which was prepared by a novel aqueous solution combustion technique, as a bone substitute in healing bone defects in vivo, as assessed by radiologic and histopathologic methods, oxytetracycline labeling, and angiogenic features in Bengal goat. Bone defects were created in the diaphysis of the radius and either not filled (group I) or filled with a HAp strut (group II). The radiologic study in group II showed...

This study examined the suitability of a nuclear imaging technique using 99mTc-tetrofosmin as an agent to assess the heart functions of healthy micropigs. The mean age of the pigs was 360 days (male), and the mean body weight was 35.3 kg ranging from 34.5-36 kg. There were no significant perfusion defects in any of the reconstructed images. Gated single-photon emission computed tomography imaging can be used to calculate the ventricular volume and ejection fraction (EF). In this case, an EF of...

Activation of Toll-like receptor-4 (TLR-4) in articular chondrocytes increases the catabolic compartment and leads to matrix degradation during the development of osteoarthritis. In this study, we determined the proteomic and genomic alterations in human chondrocytes during lipopolysaccharide (LPS)-induced inflammation to elucidate the underlying mechanisms and consequences of TLR-4 activation. Human chondrocytes were cultured with LPS for 12, 24,and 36 h to induce TLR-4 activation. The...

Adult hippocampal dentate granule neurons are generated from neural stem cells (NSCs) in the mammalian brain, and the fate specification of adult NSCs is precisely controlled by the local niches and environment, such as the subventricular zone (SVZ), dentate gyrus (DG), and Toll-like receptors (TLRs). Epigallocatechin-3-gallate (EGCG) is the main polyphenolic flavonoid in green tea that has neuroprotective activities, but there is no clear understanding of the role of EGCG in adult neurogenesis...

This study was designed to examine the effects of histamine on gastric motility and its specific receptor in the circular smooth muscle of the human gastric corpus. Histamine mainly produced tonic relaxation in a concentration-dependent and reversible manner, although histamine enhanced contractility in a minor portion of tissues tested. Histamine-induced tonic relaxation was nerve-insensitive because pretreatment with nerve blockers cocktail (NBC) did not inhibit relaxation. Additionally, K+...

Naphthyridine compounds are important, because they exhibit various biological activities including anticancer, antimicrobial, and anti-inflammatory activity. Some naphthyridines have antimitotic effects or demonstrate anticancer activity by inhibiting topoisomerase II. These compounds have been investigated as potential anticancer agents, and several compounds are now part of clinical trials. A series of naphthyridine derivatives were evaluated for their in vitro cytotoxic activities against...
