본 연구는 지리정보시스템과 원격탐사자료를 이용하여 도시공간구조를 파악하는데 목적이 있다. 특히 본 연구는 거대도시와 중소도시의 중간규모인 대도시의 공간구조를 대구광역시와 그 주변지역을 단위로 하는 대구광역권을 사례지역으로 선정하였다. 도시구조는 인구 및 직업밀도를 기준으로 분석하였다. 이 분석을 위하여 1995, 2000, 2005년도의 Landsat TM 5 위성영상자료를 지리정보시스템과 연계하여 피복분석을 통하여 활용되었다. 공간구조는 인구밀도와 직업밀도의 거리조락함수를 추정함으로써 파악되었다. 분석결과... -

큰 입사각을 가진 탄성파 반사법과 굴절법 자료의 분석은 지각 규모의 구조 연구에서 중요한 역할을 한다. 그러나, 관측된 자료로부터 적합한 속도 구조 모델을 바로 얻는 것은 상당히 어려운 일이며, 지각 구조 분석은 본질적으로 비선형 문제이기 때문에 구조 모델을 단계적으로 향상 시켜야만 한다. 광각 지각 구조 모델링에는 위상식별과 시행착오 전진 모델링과 같은 몇 가지 주관적인 과정들이 있다. 광각 자료 분석에서 이러한 주관적인 과정들은 결과 모델들의 유일성과 신뢰성을 감소시키기 때문에, 분석절차에서 주관성을... -

primary, secondary, and tertiary structure and the prediction of post-translational modifications of NSP4 from diarrheic and non-diarrheic piglets revealed no apparent differences. Sequence analysis indicated that nsp4 genes have a multi-phyletic evolutionary origin and exhibit species independent genetic diversity. The results emphasize the evolution of the E9 nsp4 genotype from the E1 genotype and suggest that the diarrhea-inducing capability of porcine RVs may not be exclusively linked to its... -

Three-dimensional quantitative structure-activity relationship (3D-QSAR) analysis was performed to build highly reliable and predictive CoMSIA models with cross-validated q2 values of 0.816 and 0.702, respectively. Our results suggest that long alkyl chains and a 1R, 2R configuration of the propyl group are important for the cytotoxic activities of arylpropyl sulfonamides. Moreover, the introduction of small hydrophobic groups in the... -

B13 analogues are being considered as therapeutic agents for cancer cells, since B13 is a ceramide analogue and inhibits ceramidase to promote apoptosis in cancer cells. B13 sulfonamides are assumed to have biological activity similar to B13, since they are made by bioisosterically substituting the carboxyl moiety of B13 with sulfone group. Twenty B13 sulfonamides were evaluated for their in vitro cytotoxicities against human colon cancer HT-29 and lung cancer A549 cell lines using MTT assays.... -

molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA). We obtained highly reliable and predictive CoMSIA models with cross-validated q2 values of 0.707 and 0.753 and CoMSIA contour maps to show the structural requirements for potent activity. These data suggest that the amide group of B13 could be replaced by thiourea, that the stereochemistry of 1,3-propandiol may not be essential for activity and that long alkyl chains increase cytotoxicity. -

into three groups with significant subpopulation differentiation. The results indicated moderate genetic variation within and no clear geographic or genetic structure between the studied populations, implying moderate gene flow can play an important role in differentiation and distri- bution of genetic diversity among populations. Several factors have shaped the genetic structure and diversity of AMV: selection, recombination/reassortment, gene flow, and random processes such as founder effects. -

Isotropic pitch-based fibers produced from coal tar pitch with the melt-blowing method were carbonized at temperatures ranging from 800 to 1600oC to investigate their crystalline structure and physical properties as a function of the carbonization temperature. The in-plane crystallite size (La) of the carbonized pitch fiber from X-ray diffraction increased monotonously by increasing the carbonization temperature resulting in a gradual increase in the electrical conductivity from 169 to 3800... -

Taguchi’s experimental design was employed in the melt spinning of molten mesophase pitch to produce carbon fibers. The textures of the obtained carbon fibers were radial with varied crack angles, as observed by scanning electron microscopy and polarized optical imaging. The diameter, crack angle, preferred orientation, and tensile modulus of the produced samples were examined to investigate the influence of four spinning variables. The relative importance of the variables has been emphasized...
