  • Analysis techniques using stereo-photos of object is used widely in close-range-photogrammetry field. but, there is difficulty to use metric camera for specialist. In this study, stereo images were acquired using metric camera and general digital camera about slide in Youngdong area. And they were generated two DEMs based metric camera and digital camera. And it was analyzed the correlation of two DEMs. Therefore, in research that was presented effectiveness of digital camera take the place of metric camera for slope analysis.

  • The most cultural heritages are composed of piled multi-block systems which are vulnerable to earthquakes. The stone of low height tends to slide when the excitation such as earthquake is applied and this sliding motion has effects on the whole response of the structure. In this study, analytical method of sliding motion of the piled multi-block systems considering horizontal rotation is developed and compared with shaking table test results. It is shown that the nonlinear analysis of sliding motion of multi-block system leads to satisfactory results.

  • 근접장 광학 현미경에 사용되는 다양한 탐침 중 가장 널리 사용되는 근접장 탐침은 잡아끌거나 식각하는 방식으로 첨단부를 뽀족하게 한 후 수십 내지 수백 나노미터 직경의 개구 만을 남겨두고 금속 코팅한 광섬유 탐침이다. 하지만 이렇게 제작되는 광섬유 탐침에는 뽀족한 기하학적인 모양과 깨지기 쉬운 재질 특성으로 인하여 내구성이 떨어지고 작은 개구 각도로 인하여 광 전달율이 매우낮으며 탐침을 근접장 영역에 진입시킨 후 시료와 탐침 간의 거리를 유지시키기 위해서 매우 복잡한 거리 유지 장치가 필요하다는 단점들이 있다. (중략)

  • 최근 들어 단일 양자점이나 단일 분자에 대한 분광 연구가 매우 관심을 끌고 있는데, 이는 미세구조 물질의 근본 물성을 밝히고자 하는 물리적인 관점뿐만 아니라 이를 실제적으로 이용하려는 실용적인 관점에서도 매우 중요한 주제이기 때문이다. 그러나 단일 양자점이나 단일 분자의 분광을 위해서는 공간적인 분해능이 우수할 뿐만 아니라 그 계에서 나오는 매우 미약한 광 신호를 검출하여야 하는 고도의 기술이 필요하다. (중략)

  • 근접장 측정에서 가장 많이 쓰이는 근접장 광섬유 탐침은 몇가지 단점을 가지고 있다. 단점 중 하나는 광 전달율이 매우 낮다는 점이다. 전형적으로 근접장 광섬유 탐침의 aperture가 100nm일때 빛이 통과할 때의 광 전달율은 $10^{-5}$만큼 떨어진다. 그리고 sample과 probe간의 수십 nm의 근접장거리를 유지하기 위해 복잡한 장치가 필요하다는 점이다. 이러한 단점을 보완하여 본 연구실에서는 근접장 측정에서 핵심이 되는 근접장 광섬유 탐침의 새로운 개념인 나노 탐침 제작을 연구하였다. (중략)

  • 전기 전자 소자를 제작하는 방법으로 Langmuir-Boldgett(LB)법이 많은 관심을 받고 있다. 수면위에 형성된 단분자막을 압축 또는 확장하면, 분자가 배향하는 과정에서 맥스웰 변위전류(MDC)가 흐른다. MDC는 전속밀도의 변화에 기인해서 흐르므로 MDC를 측정하는 것에 의해 분자의 동적 거동 관찰할 수 있다. 단분자막을 압축하는 속도와 분자면적은 서로 선형적인 관계를 갖고 있다. 본 연구에서는 압축속도를 30, 40, 50mm/min으로 달리하여 단분자막의 동적 거동을 관찰하였으며 LB법을 이용하여 Arachidic acid 단분자를 slide glass 위에 Y-type으로 9$\sim$21층의 다층막을 누적하여 Au/Arachidic acid/Al 소자를 제작하였다. 또한 Metal-Insulator-Metal(MIM) 소자의 I-V 특성을 측정하여 전극간의 거리가 커질수록 절연특성이 좋아짐을 확인하였다.

  • This study was undertaken to investigate the direct effect of three different kinds of steroid to Trichophyton(T.) mentagrophytes growth in vitro. A loopful of T. mentagrophytes was inoculated into Sabouraud's media and Sabouraud's media containing various concentrations of dexamethasone (0.04%-0.00004%) prednisolone (0.25%-0.00025%), triamcinolone acetonide (0.2%-0.0002%), Sabouraud's media containing imidazole nitrate (econasole nitrate) 10 micro gm. per cc. of media, and Sabouraud's media containing econazole nitrate $10{\mu}g$ per cc. of media of various dexamethasone concentrations (0.04%-0.00004%). After inoculation they were left for two weeks at room temparature and the colony diameter were compared between Sabouraud's media and Sabouraud's media containing various concentrations, of three different steroids, Sabouraud's media containing econazole nitrate and Sabouraud's media containing econazole nitrate of various dexamethasone concentrations. For complementary study, hanging slide culture were done between Sabouraud's media and Sabouraud's media containing various dexamethasone concentrations to compare the degree of branching of hyphae and sporulation serially. The study results were as follows: 1. There is no significant difference in growth rate of T. mentcgrophytes between Sabouraud's media and Sabouraud's media containing various concentrations of three different steroids. 2. There is no significant difference in growth rate of T. metagrophytes between Sabouraud's media containing econazole nitrate 10 micro gm per cc. of media and Sabouraud's media containing econazole nitrate 10 micro gm per cc. of media of various dexamethasone concentrations. 3. In hanging slide culture, there is no significant difference in branching of hyphae and sporulation between Sabouraud's media and Sabouraud's media containing various dexamethasone concentrations.

  • Unlike most bacteria, Treponema pallidum subspecies cannot be readily isolated or sustained in cell culture for numerous generations. In korea, two non treponemal tests are currently considered as standard; the VDRL slide test and RPR card test. These tests are based on an antigen composed of an alcoholic solution containing measured amount of cardiolipin, cholesterol, and sufficient purified lecithin to produce reactivity. The nontreponemal reagin tests measure immunoglobulin M (IgM) and IgG to lipoidal material released from damaged host cells as well as to lipoprotein-like material and possibly by cardiolipin released from the treponemes. The object of the evaluation was to evaluate the performance of the Mediace RPR kit on the automated biochemistry analyzer system as a method for screen method of syphilis as well as to identify BFP possibility. For evaluation of routine screening test, a total 2,380 specimens tested by Mediace RPR from 28th Oct, 2007 to 22th Feb, 2008. For evaluation of BFP possiblility, we measured samples which have potential BFP reaction in Syphilis test such as ANA (anti-nuclear antibody) positive (135 samples), CRP (C-reactive protein) positive (100 samples), RF (Rheumatoid factor) positive (26 samples), and other potential BFP cases (17 samples) including total 278 samples. These samples were tested quantitative test Mediace RPR with Hitachi 7600 P module. For comparison with current manual test, VDRL slide test were performed. Of these 2380 specimens, 2350 were negative, 30 were positive, and one were positive with TPHA. Both methods agreed for 2356 (98.9%) samples. Of the 30 samples showed positive results over 1.0 R.U, 6 samples showed positive results with VDRL test. Of these 6 samples, 1 samples showed positive with TPHA test. The combination of the Automated Biochemistry analyzer and VDRL test for retest can be increase efficiency of syphilis screening test.

  • 유기발광물질 $Alq_3$(alumina quinoline)의 단일박막을 열 증착(thermal evaporation)방법에 의하여 실리콘(c-Si)기판과 슬라이드유리(slide glass) 기판위에 제작하였다. 박막 제작 후 가변입사각운광타원계(VASE : Variable Angle Spectroscopic Ellipsometer)를 사용하여 1.50~5.0 eV 광 에너지 영역에서 타원 각(ellipsometry angle) ${\Delta}$, ${\Psi}$를 측정하였다. 이 측정결과들을 Jellison Modine 분산관계식을 사용하여 최적맞춤하고, 매개변수들을 구하여 박막의 광학상수인 굴절계수와 소광계수를 결정하였다. 결정한 광학상수의 정확성올 확인하기 위하여 투과율을 전산 시늉하고, 흡수계수(absorption coefficient)와 분광광도계로 측정한 흡광도(absorbance)의 스펙트럼 비교로 분석의 정확성을 확인하였다.

  • A study of occlusal relationship and TMJ dysfunction, parafunctional relationship and TMJ dysfunction using PRI was investigated in 23 dental students without history of being treated, ranging from 19 to 24 years old. The author used Denar Pantronic and D5-A articulator to study above. The obtained results were as follows : 1. Distribution of PRI in experimental subjects was as follows. None 13%, Slight 43%, Moderate 40%, Severe 4% Prevalance of TMJ Dysfunction was 87% 2. PRI scores of occlusal group Aoi (less than 5 in Helkimo occlusion/articulation index) was $11.72\pm2.32$ , those of occlusal group Boi (more than 5 in Helkimo occlusion/articulation index) 23.0 $\pm$ 8.06. There was a significant difference between group Aoi and group Boi(P<0.01) 3. PRI scores of occlusal group Ald (no eccentric interference, less than 0.5mm in lateral shift of slide in centric) was 12.0 $\pm$ 2.49, those of occlusal group Bld(no eccentric interference, less than 0.5mm in lateral shift of slide in centric) 24.5$\pm$5.33 There was a significant difference between group Ald and group Bld(P<0.05) 4. Prevalance of parafunction subjects(%) was 65.2%. 5. PRI scores of parafunction group was 21.6 $\pm$ 9.48, those of nonparafunctional group 18.7 $\pm$ 9.06. There was not significant difference between parafunctional group and nonparafunctional group(P>0.1)
