The purpose of this study is to design an artificial intelligence classification model using an AI education platform, and an AI·science convergence program that can be applied to elementary education with the AI classification model. First, an AI classification model was created that has been trained with image data of four representative rock types in the elementary science curriculum. With a recognition rate of 89.1% for the rock samples, it can be fully utilized in the classroom. Based on it, a six-hour-program was developed for elemontary school education. This program was developed based on the 2015 Science Curriculum and the artificial intelligence area of the Standard Model of Next-generation Software Education, and was reviewed by three elementary science education experts and three software education experts to ensure feasibility. The program is easy to be applied to classrooms and will meet the expectations of improving students’ science core competencies and artificial intelligence performance expectation on the Standard Model of Next-generation Software Education.

마이크로 컴퓨터는 산업적으로 대형기기와 사람을 연결해 주어 생산정보, 설계정보등의 처리 및 생산공정상의 공정제어장치의 중추적 역할을 담당하고 있다. 앞으로의 하드웨어(hardware) 소 프트웨어(software)의 경향이 더욱 낮은 가격으로 많은 처리 \ulcorner력을 갖는 추세이므로 이의 적 절한 응용분야를 택하여 개발하면 고도화된 신기술로 생산성이 향상될 것이다. 우리나라에서도 생산성 향상 및 국제 경쟁력 향상을 위해 마이크로 프로세서의 적절한 응용이 불가피하다. 이에 본 해설은 마이크로 프로세서의 기본적 개념과 이의 산업적 응용에 대하여 간단히 서술하고자 한다.

Porcine epidemic diarrhea (PED) is a highly contagious enteric swine disease. The large economic impact of PED on the swine industry worldwide has made the development of an effective PED vaccine a necessity. S0, a truncated region of the PEDporcine epidemic diarrhea virus (PEDV) spike protein, has been suggested as a candidate antigen for PED subunit vaccines; however, poor solubility problems when the protein is expressed in Escherichia coli, and the inherent problems of subunit vaccines, such as low immunogenicity, remain. Flagellin has been widely used as a fusion partner to enhance the immunogenicity and solubility of many difficult-to-express proteins; however, the conjugation effect of flagellin varies depending on the target antigen or the position of the fusion placement. Here, we conjugated flagellin, Vibrio vulnificus FlaB, to the N- and C-termini of S0 and evaluated the ability of the fusion to enhance the solubility and immunogenicity of S0. Flagellin conjugation in the presence of the trigger factor chaperone tig greatly improved the solubility of the fusion protein (~up to 99 %) regardless of its conjugation position. Of importance, flagellin conjugated to the N-terminus of S0 significantly enhanced S0-specific humoral immune responses compared to other recombinant antigens in Balb/c mice. The mechanism of this phenomenon was investigated through in vitro and in vivo studies. These findings provide important information for the development of a novel PED vaccine and flagellin-based immunotherapeutics.
