Purpose: Testing for autoantibodies to extractable nuclear antigens (ENAs) plays an important role in the diagnosis and managementof systemic rheumatic disease. Currently, no gold standard tests are available for detecting anti-ENAs. To address this gap, weaimed to identify an assay that exhibits satisfactory diagnostic performance in the detection of five common anti-ENAs by comparingtwo commonly used assays, an automated fluorescent enzyme immunoassay (FEIA) and a microplate ELISA assay. Materials and Methods: Sera from 100 patients with systemic rheumatic disease were collected and assayed with FEIA and microplateELISA to detect anti-ENAs. Statistical analyses were performed to check the agreement rate between the two platformsusing kappa coefficients. Analytical sensitivity and specificity for each assay were calculated. Results: The concordance rates between ELISA and FEIA ranged from 89% for anti-RNP to 97% for anti-Scl-70, and the kappa coefficientsof the two assays were in the range of 0.44 to 0.82. Between the two assays, a significant difference in sensitivity and specificitywas seen only for anti-Sm and anti-RNP, respectively. Conclusion: In this study, FEIA and ELISA showed comparable efficiency for detecting anti-ENAs.

Recently, 3D seismic imaging techniques have been highlighted with increasing international demands on the discovery of new oil fields as well as the site characterization and CO2 monitoring in carbon capture and storage. Because 3D seismic data can be distorted by various types of seismic anisotropy, a 3D anisotropic seismic imaging technique is required. In this study, we explain the geological reasons for seismic anisotropy and the influence of seismic anisotropy on 3D seismic data. Then, we introduce international research trends in anisotropic seismic imaging depending on seismic modeling, full-waveform inversion, and reverse-time migration. Finally, we introduce the current status and future trends in Korean 3D anisotropic seismic imaging technology. 최근 3차원 탄성파 영상화 기술이 신규 유전 개발과 이산화탄소 지중저장소 탐사 및 모니터링에 대한 국제 사회의 수요가 증가함에 따라 큰 주목을 받고 있다. 3차원 탄성파 탐사자료는 다양한 형태의 탄성파 이방성에 의해 왜곡될 수 있기 때문에 이를 고려할 수 있는 이방성 탄성파 영상화 기술이요구된다. 본 총설에서는 다양한 형태의 탄성파 이방성의 원인과 탐사 자료에 미치는 영향을 설명하고, 모델링, 완전파형역산, 역시간 구조보정 기술을 중심으로 이방성 영상화 기술 개발 동향을 소개한다. 마지막으로 3차원 이방성 탄성파 영상화 기술의 국내 개발 현황과 앞으로의 전망을 소개한다.

PURPOSE. The purpose of this study was to assess the impact of the core materials, thickness and fabrication methods of veneering porcelain on prosthesis fracture in the porcelain fused to metal and the porcelain veneered zirconia. MATERIALS AND METHODS. Forty nickel-chrome alloy cores and 40 zirconia cores were made. Half of each core group was 0.5 mm-in thickness and the other half was 1.0 mm-in thickness. Thus, there were four groups with 20 cores/group. Each group was divided into two subgroups with two different veneering methods (conventional powder/liquid layering technique and the heat-pressing technique). Tensile strength was measured using the biaxial flexural strength test based on the ISO standard 6872:2008 and Weibull analysis was conducted. Factors influencing fracture strength were analyzed through three-way ANOVA (α≤.05) and the influence of core thickness and veneering method in each core materials was assessed using two-way ANOVA (α≤.05). RESULTS. The biaxial flexural strength test showed that the fabrication method of veneering porcelain has the largest impact on the fracture strength followed by the core thickness and the core material. In the metal groups, both the core thickness and the fabrication method of the veneering porcelain significantly influenced on the fracture strength, while only the fabrication method affected the fracture strength in the zirconia groups. CONCLUSION. The fabrication method is more influential to the strength of a prosthesis compared to the core character determined by material and thickness of the core.
