    Master본 연구에서는 설명 문장 생성을 통한 해석 가능한 시각적 질의응답 모델과 학습 방법을 소개한다. 설명 문장은 시각적 질의응답 모델이 응답을 예측하는 데에 적절한 이미지 및 질문 정보의 논리적인 연결과 정답 추론 과정이 함의되어있을 것으로 기대된다. 이를 바탕으로, 시각적 질의응답 예측과 그에 대한 설명 문장 생성을 동시에 수행하는 모델을 제시하고, 여러가지 학습 기술을 통해 학습하고 검증함으로써, 설명 문장 생성과 질의응답 예측 두 가지 과정 사이에 주고받는 상호작용에 대해 분석한다. 그리고 이러한 상호작용을 적극적으로 활용할 수 있는 보다 개선된 시각적 질의응답 모델을 제안하고, 모델의 학습 결과를 바탕으로 설명 문장의 특성을 활용하여 시각적 질의응답 추론 과정을 개선함으로써 시각적 질의응답 모델을 더욱 발전시킬 수 있는 방향을 논의한다

    Performance comparison and evaluation of interferon-gamma assay kit for bovine tuberculosis diagnosis

    In Korea, bovine tuberculosis (bTB) is a representative zoonotic disease that causes considerable economic loss. In determining the positive bTB, the ELISA method for examining the amount of interferon- gamma (IFN-γ) is included in Koreas diagnostic standard method. Recently, commercially available BIONOTE TB-Feron ELISA Plus (TB-Feron Plus) that detects IFN-γ has been introduced. However, since the scientific basis for the performance is limited, we evaluated performance by comparing it with the results of another IFN-γ ELISA assay kit (BOVIGAM Ⓡ ) certified by Office International des Epizooties. In our research, 42 positive blood samples preliminarily tested with a tuberculin skin test and/or BOVIGAM Ⓡ and 54 negative blood samples collected from three bTB free farms were subjected to IFN-γ assay using the TB-Feron Plus and the BOVIGAM Ⓡ , respectively. The result shows that the sensitivity, specificity and accuracy were 81.0% (34/42), 100% (54/54), 91.7% (88/96) in TB-Feron Plus kit and 78.6% (33/42), 100% (54/54), 90.6% (87/96) in BOVIGAM Ⓡ kit, respectively. Moreover, the overall accordance percentage of the two kits was 99.0% (95/96) and there was almost perfect agreement between two assays (Kappa=0.977, P<0.0001). Furthermore, additional studies confirmed that elevated lymphocyte numbers in blood did not interfere with the results of the TB-Feron Plus kit. And, delayed time from sampling to culture decreased the optical density (OD) value. Therefore, we concluded that the TBFeron Plus kit was not inferior to BOVIGAM Ⓡ in performance. High lymphocyte numbers in blood did not impact on TB-Feron Plus results, while delayed time before culture interfered with OD value.N
